Streaming now a days have been of great use when comes to Social Media. Streaming of data have made it easy for Companies to understand the pros and cons of their product. Streaming acts as a survey now a days which a few years ago were done by a team of individual using pen and papers. In order to collect and process the streaming data from various streaming sites to produce an analytical report that helps to get a clear pictorial representation of events, the assets of streaming process generates a huge volume of real time data mainly referred to as “Big Data.” In order to aggregate, store and analyses the streaming data that are being generated Day-By-Day we get into the concept of Hadoop and Flume Technologies, API that helps to collect data from Twitter/other streaming sites by using “#” tag/Keywords. Tweets by the News channel and retweets by the public are being collected.

The determinants of the strategies to be employed by video streaming sites are application (mobile devices or web browsers) and container of the video application. They affect video streaming network characteristics, which is often the traffic flow, and its quality. It is against this background that studies on streaming strategies suggested the need to investigate and identify the relationship between buffer time, video stream protocol, packet speed and size, upload time, and waiting period, specifically to aid network administrative support in case of network traffic bottlenecks. In view of this, this study investigates the network characteristics of YouTube and Vimeo, using experimental methodology, and involving WireShark as network analyzer. Google Chrome and Firefox are the web browsers employed, while packet size, protocols, packet interval, TCP window size and accumulation ratio are the metrics. Short ON-OFF, Long ON-OFF, and No ON-OFF cycles are the three streaming strategies identified. It is further shown that both Vimeo and YouTube employ these strategies but the choice depends on the container of the video streamed.

Live streaming is one of the modern methods that allows sellers to create, transmit, or broadcast some content on the internet in real-time, and it has been used by many small individual merchants. Understanding how live streaming contributes to online consumption is becoming increasingly important in social commerce as the live-streaming industry has grown more and more popular. However, the number of studies on live streaming is still quite limited in Vietnam. Therefore, this research will look at the mechanism that enables live streaming to boost customer trust in streamers. Using PLS-SEM on a sample of 360 respondents who viewed selling live streams on social network sites in Vietnam, we discovered that other members' endorsement, value similarity, hedonic value, and utilitarian value contribute to good para-social interaction. Next, utilitarian and hedonic values, streamer product expertise, and para-social interaction all positively affect trust in the streamers. The findings could help live-streaming sellers better understand their social interactions with viewers, resulting in increased customer trust. Doi: 10.28991/ESJ-2023-07-03-06 Full Text: PDF

Online technology and streaming video have the potential to generate tremendous interest and motivation in ESL/EFL students. Unfortunately, as the basis for a task-based language teaching (TBLT) program, such technology often places students in a passive position and limits inter-student communication. This paper describes a successful TBLT course at Tokyo’s Meiji University, and explores some of the methodology for exploiting the motivational potential of streaming video sites, while ensuring that students use the target language both productively and receptively.

✓ Treatment of brain tumors by intra-arterial (IA) chemotherapy is occasionally complicated by sites of focal toxicity in the brain and retina. A possible cause of focal toxicity is non-uniform drug delivery due to intravascular drug streaming. To investigate this phenomenon in vivo, the authors examined the distribution of drug delivery after internal carotid artery (ICA) infusion in rhesus monkeys. Carbon-14 (14C)-labeled iodoantipyrine was delivered into the ICA of eight monkeys at slow infusion rates (1% to 2% of ICA flow) or at fast infusion rates (20% of ICA flow) combined with additional techniques to promote mixing with ICA blood. Two monkeys received intravenous (IV) 14C-antipyrine. Uniformity of delivery was assessed by comparing high-to-low ratios of isotope concentration in four brain regions evaluated by quantitative autoradiography. There was striking non-uniformity of drug delivery in the slow IA infusion group, with as much as 13-fold differences in drug concentration in anatomically contiguous areas. The values of high-to-low concentration ratios (mean ± standard deviation) in individual autoradiographic planes were: 1) frontoparietal cortex: slow IA infusion 4.54 ± 2.07, fast IA infusion 1.71 ± 0.31, IV infusion 1.30 ± 0.174; 2) frontoparietal white matter: slow IA infusion 2.94 ± 1.45, fast IA infusion 1.59 ± 0.41, IV infusion 1.34 ± 0.21; 3) temporal cortex: slow IA infusion 5.43 ± 3.57, fast IA infusion 1.69 ± 0.24, IV infusion 1.67 ± 0.25; 4) basal ganglia: slow IA infusion 3.6 ± 2.9, fast IA infusion 1.18 ± 0.10, IV infusion 1.09 ± 0.04. Differences between concentration ratios after slow IA and fast IA infusion are significant (p < 0.01); those between fast IA and IV infusion are not significant. Intra-arterial drug administration at infusion rates analogous to those currently used clinically results in drug streaming with markedly heterogeneous drug deposition in the perfused hemisphere. This may cause suboptimal drug levels in the tumor, and toxic levels at sites within the perfused hemisphere. This effect can be abrogated by techniques that eliminate drug streaming.

ABSTRACT Models of the decoupling of baryons and photons during the recombination epoch predict the existence of a large-scale velocity offset between baryons and dark matter at later times, the so-called streaming velocity. In this paper, we use high resolution numerical simulations to investigate the impact of this streaming velocity on the spin and shape distributions of high-redshift minihaloes, the formation sites of the earliest generation of stars. We find that the presence of a streaming velocity has a negligible effect on the spin and shape of the dark matter component of the minihaloes. However, it strongly affects the behaviour of the gas component. The most probable spin parameter increases from ∼0.03 in the absence of streaming to ∼0.15 for a run with a streaming velocity of three times σrms, corresponding to 1.4 km s−1 at redshift z = 15. The gas within the minihaloes becomes increasingly less spherical and more oblate as the streaming velocity increases, with dense clumps being found at larger distances from the halo centre. The impact of the streaming velocity is also mass-dependent: less massive objects are influenced more strongly, on account of their shallower potential wells. The number of haloes in which gas cooling and runaway gravitational collapse occurs decreases substantially as the streaming velocity increases. However, the spin and shape distributions of gas that does manage to cool and collapse are insensitive to the value of the streaming velocity and we therefore do not expect the properties of the stars that formed from this collapsed gas to depend on the value of the streaming velocity. The spin and shape of this central gas clump are uncorrelated with the same properties measured on the scale of the halo as a whole.

Streszczenie:

Federated learning is a decentralized learning framework where participating sites are engaged in a tight collaboration, forcing them into symmetric sharing and the agreement in terms of data samples, feature spaces, model types and architectures, privacy settings, and training processes. We propose PubSub-ML, Publish-Subscribe for Machine Learning, as a solution in a loose collaboration setting where each site maintains local autonomy on these decisions. In PubSub-ML, each site is either a publisher or a subscriber or both. The publishers publish differentially private machine learning models and the subscribers subscribe to published models in order to construct customized models for local use, essentially benefiting from other sites' data by distilling knowledge from publishers' models while respecting data privacy. The term “model streaming” comes from the extension of PubSub-ML to decentralized data streams with concept drift. Our extensive empirical evaluation shows that PubSub-ML outperforms federated learning methods by a significant margin.

Big Data constituting from the information shared in the various social network sites have great relevance for research to be applied in diverse fields like marketing, politics, health or disaster management. Social network sites like Facebook and Twitter are now extensively used for conducting business, marketing products and services and collecting opinions and feedbacks regarding the same. Since data gathered from these sites regarding a product/brand are up-to-date and are mostly supplied voluntarily, it tends to be more realistic, massive and reflects the general public opinion. Its analysis on real time can lead to accurate insights and responding to the results sooner is undoubtedly advantageous than responding later. In this paper, a cloud based system for real time targeted advertising based on tweet sentiment analysis is designed and implemented using the big data processing engine Apache Spark, utilizing its streaming library. Application is meant to promote cross selling and provide better customer support.

In the emerging scholarship on live-streaming sites, the role of gender has been relatively overlooked. This article aims to address this oversight by capturing the controversial rise of nüzhubo (Chinese for ‘female casters’) in the Chinese live-streaming platform, Douyu. Through ethnographic research on Douyu over 2 years, we have witnessed female performers who – motivated by both entrepreneurial spirit and creative agency – have embraced new forms of performative practices in, and around, video game commentary cultures. We begin with a brief contextualizing the gendered nature of media in the history of Chinese video sites and how theories around gender – especially gender performativity – might be adapted. While acknowledging the homogenizing effect of the term nüzhubo, we focus on two performers on Douyu – Hani9 and Nvliu – that are challenging conventional nüzhubo tropes. We argue for a situated notion of gender performativity that also engages with the platform-specific social, cultural and technical infrastructures – ‘platformativity’ to use Thomas Lamarre’s word.

Purpose – -- The purpose of this paper is to provide a selected list of free and subscription web resources for film and television (screen) studies. Design/methodology/approach -- Reference sources on film and other media studies were located, evaluated, and selected. The list is divided into four broad research categories; research databases and film catalogs (subscription products); film and television catalogs/databases (gratis); historical film streaming sites; and film studies portal sites. Findings -- There are a wide variety of resources available online that users can freely access as well as robust subscription products currently available to libraries to support research in film and television studies. Students and scholars can use both free and fee-based sites for film catalogs, film studies journal indexes, streaming video content, and other information and analysis on visual media. Originality/value -- There has not been a bibliographic list of online film studies resources undertaken since 2005, and many new web resources as well as databases have emerged in the field. The annotated list of resources in this study seeks to supplement and update what has been previously discussed in the LIS literature on web-based reference sources available for libraries supporting film and television studies.

Cytoplasmic dynein functions at several sites during mitosis; however, the basis of targeting to each site remains unclear. Tandem mass spectrometry analysis of mitotic dynein revealed a phosphorylation site in the dynein intermediate chains (ICs) that mediates binding to kinetochores. IC phosphorylation directs binding to zw10 rather than dynactin, and this interaction is needed for kinetochore dynein localization. Phosphodynein associates with kinetochores from nuclear envelope breakdown to metaphase, but bioriented microtubule (MT) attachment and chromosome alignment induce IC dephosphorylation. IC dephosphorylation stimulates binding to dynactin and poleward streaming. MT depolymerization, release of kinetochore tension, and a PP1-γ mutant each inhibited IC dephosphorylation, leading to the retention of phosphodynein at kinetochores and reduced poleward streaming. The depletion of kinetochore dynactin by moderate levels of p50(dynamitin) expression disrupted the ability of dynein to remove checkpoint proteins by streaming at metaphase but not other aspects of kinetochore dynein activity. Together, these results suggest a new model for localization of kinetochore dynein and the contribution of kinetochore dynactin.

The closure of illegal movie streaming sites IndoXXI has been a trending topic on Twitter at the end of 2019. The reaction of netizens on Twitter shows positive and negative sentiments. Until now, there have been many studies in the field of Sentiment Analysis using data in the form of Tweets from Twitter users. In sentiment analysis research, there are so many method used, and Naïve Bayes is one of it, because it is very simple and efficient. The method has advantages and disadvantages. Naïve Bayes is so sensitive in feature selection. Too many features not only increase calculation time but also reduce classification accuracy. In order to solve the disadvantages and increase the performance of the Naïve Bayes classifier, this method often being combined with many kind of feature selection methods. This research aims to classify tweets into positive and negative using the Naïve Bayes classifier combined with the Genetic Algorithm. The accuracy of Naïve Bayes before using the combination of feature selection methods reaches 79.55%. While after using feature selection methods, which is the Genetic Algorithm, accuracy increased up to 88.64%. The accuracy improved by up to 9.09%.

The large amount of bandwidth and other resources required to deliver streaming media limits the number of concurrent users. We propose a virtual active network (VAN) architecture for streaming media data delivery over wide area networks. In the proposed architecture, cooperating proxies support multiplexing and delivery of live streaming media. The hierarchical delivery structure is dynamically adjusted based on user population distribution, usage patterns, and network conditions. The proposed system architecture provides (1) reliable and high quality live streaming media delivery; (2) lower server resource requirements at the content provider sites; (3) reduced inter-ISP traffic; (4) application level routing for rapid deployment; and (5) cost-effective media data delivery. To deal with one characteristics of live broadcasting events, burst traffic at the beginning of the events, our system features a unique function that dynamically clusters multiple proxy servers to form a server farm to handle a large number of user login events when needed. Experimental results show that the proposed VAN architecture consistently delivers reliable live data streams using resources within 10 percent of the theoretically possible lower bound. The experimental results also show the effectiveness of our load balance algorithms to handle various user patterns, server capacity, and network congestion events.

P2P video streaming combining SVC and MDC In this paper we propose and evaluate a combined SVC-MDC (Scalable Video Coding & Multiple Description Video Coding) video coding scheme for Peer-to-Peer (P2P) video multicast. The proposed scheme is based on a full cooperation established between the peer sites, which contribute their upload capacity during video distribution. The source site splits the video content into many small blocks and assigns each block to a single peer for redistribution. Our solution is implemented in a fully meshed P2P network in which peers are connected to each other via UDP (User Datagram Protocol) links. The video content is encoded by using the Scalable Video Coding (SVC) method. We present a flow control mechanism that allows us to optimize dynamically the overall throughput and to automatically adjust video quality for each peer. Thus, peers with different upload capacity receive different video quality. We also combine the SVC method with Multiple Description Coding (MDC) to alleviate the packet loss problem. We implemented and tested this approach in the PlanetLab infrastructure. The obtained results show that our solution achieves good performance and remarkable video quality in the presence of packet loss.

Many academic library Web sites offer online “tours” to provide basic orientation of their collections and services. However, these tours are often merely photos, floor plans, or written descriptions. In 1999, the library at California State University, Fullerton sought to improve its own Web site orientation, by using more engaging Web technologies; namely, streaming video and interactive tutorials. A project of videotaping a full‐motion, narrated tour of the library, and then placing it on the Web site as streaming video segments, was undertaken. Additionally, interactive tutorials – quizzes written in JavaScript so as to “reply” to user prompts – were added.

Background. Due to significant emergency department overcrowding, some hospitals implemented a system of directing certain patients who were deemed not in need of emergency care to other facilities called triage away. Pathways were developed as ways to stream patient from emergency departments to primary healthcare who is presenting with less urgent or nonurgent conditions. Thus, the purpose of this study was to explore the pathways (process) for streaming patients from emergency department to primary healthcare at three different sites across Western Region of Saudi Arabia and to identify the streaming criteria and guidance. Materials and Methods. This study used a qualitative observational design. Data were collected through an unstructured observational approach, with an in-depth case study observation involving three emergency departments in the Western Region. Data were collected over three months until data saturated and recorded in the form of filed notes. Results. The results of this study explored that all CTAS-5 were streamed away either (off-site) or (on-site) from emergency department. The average of the sorting/triage cases were around 200 to 250 per shift, and about third to half of them were streamed to Primary Health Centre or Urgent Care Clinic. The total streamed patients were ranging from 50 to 60 per shift, which mean 15–20 case per hour. The study highlighted many factors that influence the practice and decision of streaming. Conclusions. In general, the term “streaming” was not as widely known among emergency clinicians, as was the term “triage.” However, streaming was performed as an evidence-based practice, and clinicians routinely acted to direct patients based on hospital policies. Although, in one hospital, some nurses hack the system to manage the flow of patients based on their intuition. In contrast, the nurses in another hospital emphasised the importance of experience and confidence in streaming improvement.

In the rapid technological development, physical boundaries have begun to disappear. The internet has created a ‘free culture’. In addition, the era is challenging the copyright concept along with the emergence of ‘digital copyright’. It has become the main commodity of Over-the-Top services providing means of communication and entertainment through the internet. Content streaming service like Netflix uses films, as well as other cinematographic works, as its main commodities. OTT Streaming media helps to protect copyright holders' rights that previously have been violated by illegal streaming sites on the internet. Unfortunately, it also raises a new question: how digital copyright-objects can be protected in this kind of service. Without physical form, copyright object can be distributed easily on the internet, and it may lead to right violations. To answer this problem, the authors aim to describe the digital copyright protection on OTT Streaming Content Media in Indonesia and compare them to the 1998 Digital Millennium Copyright Act (DMCA) of the United States of America using a descriptive-analytical approach. This study employed a normative juridical approach with secondary data. The results of this study indicate that digital copyright protection in Indonesia is still centered on conventional copyright objects, and a sui generis law is needed to provide better protection for digital copyright objects.

Recent studies have shown that auditory scene analysis involves distributed neural sites below, in, and beyond the auditory cortex (AC). However, it remains unclear what role each site plays and how they interact in the formation and selection of auditory percepts. We addressed this issue through perceptual multistability phenomena, namely, spontaneous perceptual switching in auditory streaming (AS) for a sequence of repeated triplet tones, and perceptual changes for a repeated word, known as verbal transformations (VTs). An event-related fMRI analysis revealed brain activity timelocked to perceptual switching in the cerebellum for AS, in frontal areas for VT, and the AC and thalamus for both. The results suggest that motor-based prediction, produced by neural networks outside the auditory system, plays essential roles in the segmentation of acoustic sequences both in AS and VT. The frequency of perceptual switching was determined by a balance between the activation of two sites, which are proposed to be involved in exploring novel perceptual organization and stabilizing current perceptual organization. The effect of the gene polymorphism of catechol- O -methyltransferase (COMT) on individual variations in switching frequency suggests that the balance of exploration and stabilization is modulated by catecholamines such as dopamine and noradrenalin. These mechanisms would support the noteworthy flexibility of auditory scene analysis.

We constructed three observation sites in northeastern Japan (Honjo, Kyowa, and Sennan) with condenser-type large plate electrodes (4 × 4 m2) as sensors supported 4 m above the ground and with pairs of reference electrodes buried vertically at 0.5 m and 2.5 m depth (with a ground velocity sensor at Sennan only). Electrical signals of an earthquake (M6.3) in northeastern Japan were detected simultaneously with seismic waves. Their waveforms were damped oscillations, with greatly differing signal amplitudes among sites. Good positive correlation was found between the amplitudes of signals detected by all electrodes. We propose a signal generation model: seismic acceleration vertically shook pore water in the topsoil, generating the vertical streaming potential between the upper unsaturated water zone and the lower saturated water zone. Maximum electric earth potential difference was observed when one electrode was in the saturated water zone, and the other was within the unsaturated water zone, but not when the electrodes were in the saturated water zone. The streaming potential formed a charge on the ground surface, generating a vertical atmospheric electric field. The large plate electrode detected electric signals related to electric potential differences between the electrode and the ground surface.

At present, most of medical facilities are using PACS (Picture Archiving and Communication System) to manage various medical images. PACS is a medical image management system and the main purpose of PACS is to replace conventional film with digital images and to allow medical professionals to view digital photographs or images of diagnostic tests, interpretations and related data simultaneously from multiple sites. In the paper we further propose a Cloud image data platform which is suitable for managing medical images. This platform collaborates with PACS in medical facilities and it immediately delivers images captured by equipment via parallel connection to remote server in form of parallel streaming. Taking advantage of parallel streaming technology, we have solved the medical resources sharing problem and problem caused at delivering and storing consecutive high resolution image files. Patients who are to be transferred to other medical facilities will no longer re-do all examinations. This saves medical resources and physician’s precious time. Our experiments shows our parallel streaming delivering platform improves the transmission efficiency on LAN (Local Area Network), TANet (Taiwan Academic Network) and home-group network by 45.6％, 49.4％, and 8.1％ respectively in comparison with conventional single server system using FTP transmission.

In mesophyll cells of the aquatic angiosperm Vallisneria gigantea, bundles of microfilaments (MFs) serve as tracks for the rotational streaming of the cytoplasm, which occurs along the two longer side walls and the two shorter end walls. The stationary organization of these bundles has been shown to depend on the association of the bundles with the plasma membrane at the end walls. To identify the sites of such association, the effects of cytochalasin B (CB) on the configuration of the bundles of MFs were examined. In the case of the side walls, MFs were completely disrupted after treatment with CB at 100 micrograms/ml for 24 hours. By contrast, in the case of the end walls, a number of partially disrupted MFs remained even after 48 hours of treatment. After removal of CB, a completely normal arrangement of bundles of MFs was once again evident within 24 hours after a rather complicated process of reassembly. When reassembly had been completed, the direction of cytoplasmic streaming was reversed only in a small fraction of the treated cells, suggesting that bundles of MFs are anchored and stabilized at the end walls of each cell and that the polarity of reorganized bundles and, therefore, the direction of the cytoplasmic streaming is determined in a manner that depends on the original polarity of MFs that remained in spite of the disruptive action of CB. By contrast, the direction of reinitiated cytoplasmic streaming was reversed in 50% of cells in which the bundles of MFs had been completely disrupted by exogenously applied trypsin prior treatment with CB.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract Recent observations of protoplanetary disks (PPDs) at submillimeter wavelengths have revealed the ubiquity of annular substructures that are indicative of pebble-sized dust particles trapped in turbulent ringlike gas pressure bumps. This major paradigm shift also challenges the leading theory of planetesimal formation from such pebbles by means of the streaming instability, which operates in a pressure gradient and can be suppressed by turbulence. Here, we conduct 3D local shearing box nonideal magnetohydrodynamic simulations of dust trapping in enforced gas pressure bumps, including dust backreaction. Under a moderate level of turbulence generated by the magnetorotational instability with ambipolar diffusion, which is suitable for outer disk conditions, we achieve quasi-steady states of dust trapping balanced by turbulent diffusion. We find strong dust clumping in all simulations near the gas pressure maxima, reaching a maximum density well above the threshold for triggering gravitational collapse to form planetesimals. A strong pressure bump concentrates dust particles toward the bump’s center. With a weak pressure bump, dust can also concentrate in secondary filaments off the bump’s center, due to dust backreaction, but strong clumping still occurs mainly in the primary ring around the bump’s center. Our results reveal dust-trapping rings to be robust locations for planetesimal formation in outer PPDs, while they may possess diverse observational properties.

This special issue of Television and New Media showcases current research on informal media production and distribution networks. Situated partly or wholly outside regulated, consolidated, and policy-governed audiovisual industries, the networks studied here include video circuits in West Africa, new media infrastructures in the Caribbean, user-driven streaming sites, and transnational VHS piracy. Together, these accounts provide glimpses of what may be best described as an interlocking set of informal media economies: zones of unmeasured and unevenly regulated media production and exchange, which articulate with conventional media systems in unpredictable ways.

Virtual tours using drones enhance the experience the users perceive from a place with cultural interest. Drones equipped with 360o cameras perform real-time video streaming of the cultural sites. The user preferences about each monument type should be considered in order to decide the appropriate flying route for the drone. This article describes a scheme for supporting personalized real-time virtual tours at sites with cultural interest using drones. The user preferences are modeled using the MPEG-21 and the MPEG-7 standards, while Web Ontology Language (OWL) ontologies are used for metadata structure and semantics. The Metadata-Aware Analytic Network Process (MANP) algorithm is proposed in order to weigh the user preferences for each monument type. Subsequently, the Trapezoidal Fuzzy Topsis for Heritage Route Selection (TFT-HRS) algorithm ranks the candidate heritage routes. Finally, after each virtual tour, the user preferences metadata are updated in order in order the scheme to continuously learn about the user preferences.

The purpose of the present research study was to assess the attitudes of college youth towards social networking sites and utilising other services such as YouTube etc. as tools for education. The sample for the study were selected randomly and included 180 college youth studying in Government Degree colleges of Jammu, India. Data were collected through survey method and self-prepared tool which was used to assess the attitude of college youth towards social networking sites and other services as a tool for education. Findings revealed that YouTube is used by a large number of users as compared to WhatsApp and Facebook. Majority of the undergraduate youth are using YouTube videos, WhatsApp messenger and LinkedIn for viewing and sharing educational content. It was also found that male college youth used more of LinkedIn and Twitter, while female college youth used more of Facebook, WhatsApp and YouTube. In addition to this, the study shows that no significant differences exist in the attitude and perceived impact of male and female students at the undergraduate level. However, they have equally shown positive and favourable attitude towards social networking.

At the periphery of the human placenta, trophoblast attaches to the uterine wall. The tissue interface contains many anchoring sites, with cytotrophoblast columns that form bridges between the overlying extraembryonic (villous) mesenchyme and the maternal decidual stroma beneath. From the periphery of these columns, large numbers of trophoblast cells detach, migrate through the decidua and eventually colonize and transform maternal arteries. In this way the placenta increases and gives priority to the maternal blood supply to the conceptus. We have shown that when early villous tissue is explanted on a collagen gel in serum-free medium, anchoring-site morphogenesis occurs. Thus, in the presence of placental mesenchyme but in the absence of maternal cells, contact with a permissive extracellular matrix (ECM) is necessary and sufficient for cytotrophoblast column development. Proliferation of trophoblast occurs, followed by differentiation into a columnar cell phenotype in which cells remain attached to one another and to the ECM. At this stage, interaction between fibronectin and integrin α5β1 at the cell surface stabilizes the column and the cells remain as a contiguous multilayered sheet. However, the addition of serum-free conditioned medium from first-trimester placental fibroblasts stimulates cytotrophoblast to detach from the distal column and migrate in streams across the ECM. The removal of insulin-like growth factor I (IGF-I) from the fibroblast medium decreases streaming activity, whereas the addition of exogenous IGF-I (10 ng/ml) to serum-free medium produces a streaming phenotype. In contrast, transforming growth factor β1 (10 ng/ml) maintains the cells in a tight sheet. These results suggest the possibility of a paracrine interaction between villous mesenchyme and cytotrophoblast in anchoring sites to stimulate the infiltration of the maternal ECM by trophoblast. Such a mechanism would be self-limiting because the signal diminishes with distance from the placenta.

The health crisis caused by the coronavirus (COVID-19) pandemic created an unprecedented social situation. In the most critical moments, tourism activities were cancelled or reduced to their minimum operation, creating an extreme situation of separation of a country’s heritage from residents and tourists. The objective of this work is to propose new options and strategies to reconnect the public with heritage under any circumstance and, at the same time, offer tourism services in healthy, secure conditions. Thus, live-streaming experiences of online interpretative tourist guidance were developed in heritage spaces; those visits were led by real guide-interpreters in a real environment and transmitted for remote visitors. We have called this visiting model the “Avatar Tourist Visit”. It is based on tools associated with Heritage Interpretation, Interpersonal Communication, Filmmaking and Audio-Visual Language, and Information and Communication Technologies. The methodological development of this tool was based on Design Sciences Research as the creation of a new procedure was pursued. The result is a sustainable, immersive, interactive, inclusive, unique, and resilient tourism product designed not only for times of crisis but also to connect the public with heritage at all times and ensure universal access to it. In addition, this activity constitutes a marketable experience as a specialized and customizable tourist product.

But until now in the Indonesian media industry, especially Metro TV, media convergence has notimplemented an effective system. Media industries affiliated with a group (Media Group) operate independentlyof each other with little coordination. Broadcast media industry in Indonesia is still reluctant to switch to digital broadcasting due to the high costs of replacing the analog broadcasting.

Rhodaminylated (R)-phalloidin microinjected into Paramecium tetraurelia cells at a final concentration of greater than or equal to 20 micrograms/ml produces considerable functional and structural changes. F-actin bundles (with 20 micrograms/ml phalloidin within 15 min) are formed, which subsequently (greater than 30 min) are sequestered into autophagic vacuoles; simultaneously, the originally intense fluorescence of a narrow cortical layer becomes more and more diminished. When such microinjected cells are processed for electron microscopy, they display concomitant ultrastructural alterations, namely, the formation of transcellular bundles of 5-7 nm-thick filaments, which subsequently appear in autophagosomes, as well as a considerable reduction of filamentous materials in the cortex. This, in turn, entails a considerable restructuring of the cortex, enabling free access of various structural components to the cortex. Higher doses of R-phalloidin abolish cytoplasmic streaming (e.g., 50 micrograms/ml after 20-30 min); although the cells may survive, new secretory organelles (trichocysts) are no longer docked to the cell membrane. In contrast, exocytosis of docked trichocysts (as well as subsequent membrane resealing and retrieval) is not impaired under any conditions. Cortical F-actin may account for the cytoplasmic streaming that may normally guarantee the delivery of new trichocysts to free docking sites at the cell membrane. When docking is inhibited by high R-phalloidin doses, excess free trichocysts are sequestered into autophagosomes (crinophagy). One of the most sensitive cell functions is food vacuole formation (assayed by prelabeling with India ink), which correlates with the presence of R-phalloidin labeling in the cytostomal region and around food vacuoles. The main conclusions from this work are that filamentous actin may be involved in structuring of the cortex and in cytoplasmic streaming, and may therefore influence the formation, and possibly the transcellular transport (cyclosis), of food vacuoles, as well as the docking of trichocysts, whereas it does not play a role in exocytosis per se or in the steps immediately following.

In the most recent wave of struggles a changed logic of activism is evident (Dyer-Witheford, 2015). Research on this wave has often emphasised the interactions of the digital (through online forms of activism, communication, and coordination) with the embodied (in assemblies, spatial occupations, and face-to-face encounters) (Gerbaudo, 2012). Although gender has been considered in regard to these struggles (Herrera, 2014) feminist concerns over social reproduction – concerns which have also been central to the contemporary epoch of struggle (Brown, et al, 2013) – have been largely neglected. Social reproduction refers to the capacities of populations to reproduce themselves and through this to reproduce the material basis of the economy (Bezanson and Luxton, 2006; Federici, 2012). It is a site wherein human beings and capital compete for the reproduction of living bodies, and contemporary social movements have become ground zero for such socially reproductive contestations (Thorburn, 2015). Within contemporary movements, struggles over social reproduction are increasingly channelled through digital networks as well as embodied practices. This digital-embodied convergence opens up strengths and weaknesses in the contemporary epoch of social/political contestation. In this paper I seek to explicate how alternative feminist modes of social reproduction emerge through digital networks in contemporary social movements and compare this digital social reproduction to more embodied forms also witnessed. Using a case study of Concordia University Television’s live streaming of Quebec’s 2012 student strike, as well as the live streaming initiatives in the anti-police brutality protests in Ferguson and Baltimore 2015, this paper will suggest future horizons of digital and embodied activism around social reproduction focused on media forms within social movements. Based on ethnographic research, including participant observation and interviews, I argue that the practices and projects of live streaming can expand forms of social reproduction autonomous from both the state and capital. The digital practices of social reproduction emerging in contemporary struggles can contribute to circumventing power while at the same time constituting sites of resistance within and beyond social and political contestations.

The infection process of basidiospores of the cowpea rust fungus (Uromyces vignae) was studied on living host (Vigna sinensis) and nonhost (Vicia faba) leaves using light microscopy with differential interference contrast optics. During the first 8 h, fungal development was similar on host and on nonhost leaves. Penetration and production of intraepidermal vesicles occurred in nonhost cells 4 h earlier than in host cells. Penetration frequency was also higher in nonhost leaves. These results suggest that the cuticle of the cowpea plant delays basidiospore infection. Both host and nonhost cells produced cytoplasmic aggregates during appressorium formation and again, a few hours later, during penetration of the epidermal cell wall. Cytoplasmic aggregates were also observed in cells adjacent to a collapsing cell. Papillae were observed at most infection sites in both host and nonhost cells. The nuclei of infected cells migrated towards the penetration site in both plant–pathogen combinations. Nuclear size increased considerably only in the nonhost epidermis and decreased again markedly after cell collapse. In the nonhost cells, three types of defence reactions occurred during or after formation of the intraepidermal vesicle. First, following the halt of cytoplasmic streaming, the cytoplasm of the invaded cell either contracted or disintegrated into granules. Alternatively, the cytoplasm continued streaming but darkly pigmented material encased the fungal infection structure. Key words: basidiospore, broad bean (Vicia faba), cowpea (Vigna sinensis), cowpea rust fungus (Uromyces vignae), hypersensitivity, nonhost resistance.

Since the pandemic outbreak, the Netherlands has been repeatedly gripped by protests over successive restrictions. Protesters were often characterized by aggression and violence, so they had to be demobilized to restore order to the streets. In some cases, the police were forced to use coercive measures. Nonetheless, the November 2021 protest in Rotterdam caused considerable controversy. During the demonstration, gunshots were fired at demonstrators for the first time in a dozen years. This article aims to attribute the strategy of police action during the Rotterdam protests to one of the two models determined by McPhail, Schweingruber, and McCarthy and operationalized by Rak. The study draws on qualitative source analysis and the content analysis technique. The most opinion-forming Dutch news sites, both Dutch- and English-language, were used as sources. These sources were supported by international news sites and channels on the streaming service YouTube. Additionally, the Rotterdam police’s Twitter account and the official politie.nl website were analyzed. A theoretically grounded hypothesis was posited that: during the Rotterdam protests in November 2021, the police, due to the dynamic development of the rally, used a model closer to an escalated force. However, it did not occur in its pure form.

Social media sites employ various approaches to track feelings, including diagnosing neurological problems, including fear, in people or assessing a population public sentiment. One essential obstacle for automatic emotion recognition principles is variable with fluctuating limitations, language, and interpretation shifts. Therefore, in this paper, a deep learning-based emotion recognition (DL-EM) system has been proposed to describe the various relational effects in emotional groups. A soft classification method is suggested to quantify the tendency and allocate a message to each emotional class. A supervised framework for emotions in text streaming messages is developed and tested. Two of the major activities are offline teaching assignments and interactive emotion classification techniques. The first challenge offers templates in text responses to describe sentiment. The second activity includes implementing a two-stage framework to identify live broadcasts of text messages for dedicated emotion monitoring.

Ultrasonic vibration has been applied to various molten metal processes owing to the functions of (a) improvement in wettability, (b) liquid adhesion at a vibrating end surface and (c) sono-solidification such as grain refinement. The present study is focused on the sono-solidification with acoustic cavitaion in hypereutectic Al-18mass%Si alloy. There appears an equilibrium microstructure composed of primary silicon and coupled eutectic -Al/Si phases in Al-18mass%Si alloy, however, non-equilibrium -Al grains develop along with the equilibrium phases through the sono-solidification. During the sono-solidification of Al-18mass%Si alloy, non-equilibrium -Al grains are recognized in the molten metal close to the ultrasonic radiator just before reaching the eutectic temperature of 577 oC in addition to the refined primary silicon particles. The appearance of -Al grains is understood through acoustic cavitation: ultrasound in molten Al-Si alloys exhibits two outstanding behaviors of cavitation bubbling and acoustic streaming. Firstly the de-coupled eutectic reaction, which is recognized in the solidified eutectic Al-Si alloy with severe stirring, causes divorced -Al grains by the acoustic streaming with cavitation. Secondly it is expected that high pressure of over 1 GPa generated by the collapse of cavitaion babbles leads to not only an increase in the eutectic temperature, but also higher silicon content at the eutectic point in Al-Si alloy. Consequently, non-equilibrium -Al grains are nucleated at collapsed cavitaion bubble sites, and they are characterized by higher silicon content compared with that of primary -Al grains in hypoeutectic Al-7masst%Si alloy.

Background Emergency care is facing a steadily rising demand. In response, hospitals have implemented new models of care that locate general practitioners in or alongside the emergency department. Objectives We aimed to explore the effects of general practitioners working in or alongside the emergency department on patient care, the primary care and acute hospital team, and the wider system, as well as to determine the differential effects of different service models. Design This was a mixed-methods study in three work packages. Work package A classified current models of general practitioners working in or alongside the emergency department in England. We interviewed national and local leaders, staff and patients to identify the hypotheses underpinning these services. Work package B used a retrospective analysis of routinely available data. Outcome measures included waiting times, admission rates, reattendances, mortality and the number of patient attendances. We explored potential cost savings. Work package C was a detailed mixed-methods case study in 10 sites. We collected and synthesised qualitative and quantitative data from non-participant observations, interviews and a workforce survey. Patients and the public were involved throughout the development, delivery and dissemination of the study. Results High-level goals were shared between national policy-makers and local leads; however, there was disagreement about the anticipated effects. We identified eight domains of influence: performance against the 4-hour target, use of investigations, hospital admissions, patient outcome and experience, service access, workforce recruitment and retention, workforce behaviour and experience, and resource use. General practitioners working in or alongside the emergency department were associated with a very slight reduction in the rate of reattendance within 7 days; however, the clinical significance of this was judged to be negligible. For all other indicators, there was no effect on performance or outcomes. However, there was a substantial degree of heterogeneity in these findings. This is explained by the considerable variation observed in our case study sites, and the sensitivity of service implementation to local factors. The effects on the workforce were complex; they were often positive for emergency department doctors and general practitioners, but less so for nursing staff. The patient-streaming process generated stress and conflict for emergency department nurses and general practitioners. Patients and carers were understanding of general practitioners working in or alongside the emergency department. We found no evidence that staff concerns regarding the potential to create additional demand were justified. Any possible cost savings associated with reduced reattendances were heavily outweighed by the cost of the service. Limitations The reliability of our data sources varied and we were unable to complete our quantitative analysis entirely as planned. Participation in interviews and at case study sites was voluntary. Conclusions Service implementation was highly subject to local context and micro-level influences. Key success factors were interprofessional working, staffing and training, streaming, and infrastructure and support. Future work Further research should study the longer-term effects of these services, clinician attitudes to risk and the implementation of streaming. Additional work should also examine the system effects of national policy initiatives, develop methodologies to support rapid service evaluation and study the relationship between primary and secondary care.

Learning outcomes The learning outcomes of this case are product innovation, the importance of consumer insights and data in marketing and the role of consumer insights in brand revival. Case overview/synopsis This case study is a fascinating look into how the shift from music compact disc (CDs) to streaming has completely changed consumer behavior. This change in attitude led many music labels down one of two paths as follows: shutting down the business or embracing new business models. The case study aims to bring out essential learning from a company, Saregama, that was on the verge of shutting down because of the losses incurred with the shift in consumer behavior from buying music CDs to streaming music for free on every smart device. This shift led most record companies to become shuttered. However, not all were as fortunate as Saregama, who threaded its way toward profitability. This case analyzes how Saregama turned from a loss-making business unit into a profit center by launching a breakthrough product backed by innovative thinking and strong consumer research. The researcher opted for secondary research based on reports from Deloitte and McKinsey & Company and other credible sources to understand the music streaming market in India. The study also includes excerpts from the interview of Vikram Mehra (MD of Saregama India Ltd.) to various media houses and customer reviews on e-commerce sites. Complexity academic level The case is relevant for learners studying for an undergraduate or graduate program and for discussions for modules such as marketing management and international marketing with a focus on product development and strategy. Applicability the case will provide the following exposure to the learners: the difference between corporate and marketing objectives; Using frameworks such as valuable, rare, inimitable, and organization and SAP-LAP to understand the rationale behind strategic decisions; An understanding of the importance of listening to consumers; Using the right marketing elements such as segmentation, targeting and positioning and marketing mix for a competitive marketing strategy.

We studied five young healthy volunteers who performed a "damage protocol" consisting of 240 (24 sets x 10 repetitions/set) maximal isokinetic eccentric muscle contractions (30°/s) on each leg one week apart. Biopsies were taken from the vastus lateralis on two occasions. Two biopsies were taken from within the same muscle 24 h following the damage protocol. On a second occasion a single biopsy was taken from the contralateral leg at 24 h following the same damage protocol. Biopsies at all three sites showed Z-band disruption, much greater (i.e., ∼14-fold) than is typically observed in resting biopsies, with no significant differences (ANOVA) according to site location (within legs or between legs). The within-leg coefficient of variation (CV) was, however, 41 ± 30%, and the between-leg CVs were 57 ± 36% and 68 ± 36%. Macrophage cells were also detected within the muscle, and cell numbers were not statistically different between biopsy sites. However, the within-biopsy CV = 52 ± 19% and the between-biopsy CVs of 34 ± 24% and 48 ± 27%. We conclude that eccentric contraction-induced Z-band streaming and inflammatory cell response, as detected in muscle biopsy samples from humans, is highly variable with a CV of 40-70%. Key words: muscle damage; eccentric exercise; biopsy; coefficient of variation

It has been suggested that successively presented sounds that are perceived as separate auditory streams are represented by separate populations of neurons. Mostly, spectral separation in different peripheral filters has been identified as the cue for segregation. However, stream segregation based on temporal cues is also possible without spectral separation. Here we present sequences of ABA- triplet stimuli providing only temporal cues to neurons in the European starling auditory forebrain. A and B sounds (125 ms duration) were harmonic complexes (fundamentals 100, 200, or 400 Hz; center frequency and bandwidth chosen to fit the neurons' tuning characteristic) with identical amplitude spectra but different phase relations between components (cosine, alternating, or random phase) and presented at different rates. Differences in both rate responses and temporal response patterns of the neurons when stimulated with harmonic complexes with different phase relations provide first evidence for a mechanism allowing a separate neural representation of such stimuli. Recording sites responding >1 kHz showed enhanced rate and temporal differences compared with those responding at lower frequencies. These results demonstrate a neural correlate of streaming by temporal cues due to the variation of phase that shows striking parallels to observations in previous psychophysical studies.

With advances in data collection and generation technologies, environments that produce data streams is more and more. In recent years, the network application is further universal and the applications of a single data stream transfer toward a multi-node distributed data streams, such as sensor network, network monitoring, web log analysis and the credit card transaction data of multiple sites. These data is not only real-time, continuous and large scale, but also distributed. How to manage and analyze large dynamic datasets is an important subject that researchers are faced with. In view of the situation, it presented the formalization description of homogeneous and heterogeneous distributed data stream in this paper, analyzed advantages and disadvantages of the centralized stream processing architecture and distributed streaming processing architecture, discussed the recent progress in distributed data stream classification algorithm, summed up the problems and challenges faced by the distributed data stream mining, and possible future research directions.

Social network sites like Twitter enable the creation of virtual environments where online communities are formed around specific topics. Lately, due to their increasing success, these platforms are turning out to be effective for electronic word–of–mouth communication since they can be used as another means to spread information and build a network of contacts. In this paper, Twitter is used as a proxy to measure social capital in the electronics and ICT cluster, one of the 22 clusters integrated in the Basque cluster policy. Tweets were extracted through REST and Streaming API and later on studied using Social Network Analysis, both from the static and dynamic perspective. Above all, I highlight a strong correlation at the structural and relational level, intra and inter dimensionally. The social and organizational proximity may explain the tighter relationships among affiliates, where the association that rules the cluster and other firms play an important role.

Our study analyzed the impacts of the Korean Wave on agricultural food export in Korea using a single-country gravity model. The empirical model is applied to the trade data from 2005 to 2019 for 153 countries. We added the Korean Wave as a proxy variable by collecting Korean content service exports, which include music, dramas, and movies available on streaming sites and online video services, reflecting the recent shift in media platforms. We split the data into country groups and use the Poisson Pseudo Maximum Likelihood (PPML) to solve zero-trade data. Our findings show that the Korean Wave has a impact on both agricultural products and processed foods. Specifically, agricultural products are strongly influenced by the Korean Wave in Asia, while processed foods are influenced by more diverse continents. This suggests that the Korean Wave has a significant effect on agricultural food exports. We believe our study will be used as a fundamental study to prepare measures to increase agricultural exports through analysis by country.

Este estudo teve como objetivo analisar a imagem da profissão secretarial transmitida pelos dramas sul-coreanos. A pesquisa se classifica na abordagem qualitativa e é caracterizada como descritiva e exploratória, tendo sido utilizado o método de Análise Fílmica no drama “O que há de errado com a secretária Kim?”, selecionado através do Rakuten Viki, um dos maiores sites de streaming global de produções do Leste da Ásia. Como resultado foi identificado que os dramas sul-coreanos têm transmitido uma imagem secretarial com um bom perfil profissional, através de personagens maduras que executam amplamente as atividades secretariais no que diz respeito ao planejamento, organização e execução de reuniões, viagens e eventos. Muitos dos estereótipos que acometem a profissão secretarial não foram identificados no drama analisado, dessa forma, embora o estereótipo de relacionamento entre chefe e secretaria seja muito trabalhado no drama, a personagem secretarial vem sendo construída e transmitida de forma a valorizar a profissão.
