Abstract:

When technology is scaling down, reliability and power issues are arise in the intercommunication of System on Chip (SoC). The intercommunication links are suffers with various noise sources like crosstalk, temperature variation and voltage deflection which lead to communication link failure. To get reliable system, the strong error detection and correction codes are required. In this proposed work, Crosstalk avoidance code detects and corrects of one bit error, two bit error and some of three bit errors. The Hybrid Automatic Re-transmission Request is also used when the CAC detects the burst error of three. Apart from this, the Low Power Codes are used to get low power consumption using Bus Invert (BI) technique in proposed work. The LPC code reduces the power consumption of interconnection wires using reducing switching activity. The performance of proposed work evaluated in Xilinx 14.7 in Vertex-6 Field Programmable Gated Array (FPGA) device. The proposed work is calculated of power consumption of codec module and interconnection wire, delay of CAC and LPC code and link swing voltage. This work provides 11.7% improvement in power consumption and presents high reliability than JTEC. The energy dissipation of wires in the proposed work is decreased 23.5% than un-coded schemes.

Abstract:

In this paper we formalize a combinatorial object for describing link diagrams called a Planar Diagram Code (PD-Code). PD-codes are used by the KnotTheory Mathematica package developed by Bar-Natan et al. We present the set of PD-codes as a standalone object and discuss its relationship with link diagrams. We give an explicit algorithm for reconstructing a knot diagram on a surface from a PD-code. We also discuss the intrinsic symmetries of PD-codes (i.e. invertibility and chirality). The moves analogous to the Reidemeister moves are also explored, and we show that the given set of PD-codes modulo these combinatorial Reidemeister moves is equivalent to classical link theory.

Abstract:

Due to recent advancements in big data, connection technologies, and smart devices, our environment is transforming into an “Internet of Everything” (IoE) environment. These smart devices can obtain new or special functions by reprogramming: upgrade their soft systems through receiving new version of program codes. However, bulk codes dissemination suffers from large delay, energy consumption, and number of retransmissions because of the unreliability of wireless links. In this paper, a delay-aware program dissemination (DAPD) scheme is proposed to disseminate program codes with fast, reliable, and energy-efficient style. We observe that although total energy is limited in wireless sensor network, there exists residual energy in nodes deployed far from the base station. Therefore, DAPD scheme improves the performance of bulk codes dissemination through the following two aspects. (1) Due to the fact that a high transmitting power can significantly improve the quality of wireless links, transmitting power of sensors with more residual energy is enhanced to improve link quality. (2) Due to the fact that performance of correlated dissemination tends to degrade in a highly dynamic environment, link correlation is autonomously updated in DAPD during codes dissemination to maintain improvements brought by correlated dissemination. Theoretical analysis and experimental results show that, compared with previous work, DAPD scheme improves the dissemination performance in terms of completion time, transmission cost, and the efficiency of energy utilization.

Abstract:

Free space optical (FSO) communication systems provide wireless line of sight connectivity in the unlicensed spectrum, and wireless optical communication achieves higher data rates compared to their radio frequency (RF) counterparts. FSO systems are particularly attractive for last mile access problem by bridging fiber optic backbone connectivity to RF access networks. To cope with this practical deployment scenario, there has been increasing attention to the so-called dual-hop (RF/FSO) systems where RF transmission is used at a hop followed by FSO transmission to another. In this article, we study the performance of cooperative transmission systems using a mixed RF-FSO DF (decode and forward) relay using error-correcting codes including QC-LDPC codes at the relay level. The FSO link is modeled by the gamma-gamma distribution, and the RF link is modeled by the Additive White Gaussian Noise (AWGN) model. Another innovation in this article is the use of cooperative systems using a mixed FSO/RF DF relay using quasicyclic low-density parity check (QC-LDPC) codes at the relay level. We also use the space-coupled low-density parity check (SC-LDPC) codes on the same scheme to show its importance in cooperative optical transmission but also in hybrid RF/FSO transmission. The latter will be compared with QC-LDPC codes. The use of mixed RF/FSO cooperative transmission systems can improve the reliability and transmission of information in networks. The results demonstrate an improvement in the performance of the cooperative RF/FSO DF system based on QC-LDPC and SC-LDPC codes compared to RF/FSO systems without the use of codes, but also to the DF systems proposed in the existing literature.

Abstract:

Abstract Introduction Quick Response codes, or “QR” codes, are used widely in China—for mobile payment, marketing, public transportation, and various other applications. In this study, we examined the content of websites linked from QR codes on cigarette packs collected in China. Aims and Methods In February 2017, 738 unique cigarette packs were collected from five Chinese cities (Beijing, Guangzhou, Shanghai, Kunming, and Chengdu) using a systematic protocol. Cigarette packs were coded for presence of QR codes on packaging. Packs containing QR codes were then scanned using the WeChat app. Websites sourced from QR codes were coded for required verification, website type, age- and health-related statements, engagement strategies, and marketing appeals. Results From the sample of 738 unique packs, 109 packs (14.8%) had a QR code on the packaging. The QR codes were linked to 24 unique websites of which 23 could be analyzed. All 23 unique websites were either brand-specific or social media websites; none focused on health or quit information. Of the 23 websites, only three (13.0%) websites had age-restricted site access and just six (26.1%) had any mention of health-related risks associated with product usage. Engagement strategies and/or marketing appeals were found on 20 (87.0%) websites. Conclusions The Chinese tobacco industry uses QR codes on cigarette packaging to link to web-based marketing content including social media recruitment, contests and giveaways, and product advertisement. It is important to understand where packs send consumers online and what messages they receive, and to consider QR codes on packaging when drafting policy. Implications Scanning QR codes in China is a commonplace activity. The authors are aware of no published studies on the role QR codes play on the marketing of cigarette packs, in China or elsewhere. This study demonstrates QR codes on cigarette packs can expose users and nonusers to cigarette marketing on interactive websites and protobacco social media pages, mostly without restrictive access or health warnings. This is an area that health authorities can consider regulating, given that this is a channel through which the tobacco industry can communicate with current and potential consumers.

Abstract:

Free Space Optics (FSO) links are affected by several impairments: optical turbulence, scattering, absorption, and pointing. In particular, atmospheric optical turbulence generates optical power fluctuations at the receiver that can degrade communications with fading events, especially in high data rate links. Innovative solutions require an improvement of FSO link performances, together with testing models and appropriate channel codes. In this paper, we describe a high-resolution time-correlated channel model able to predict random temporal fluctuations of optical signal irradiance caused by optical turbulence. Concerning the same channel, we also report simulation results on the error mitigation performance of Luby Transform, Raptor, and RaptorQ codes.

Abstract:

Background: Multiple studies have questioned the validity of clinical codes in hospital administrative data. We examined variability in reporting a postoperative ileus (POI). Objective: We aimed to analyse sources of coding variations to understand how clinical coding professionals arrive at POI coding decisions and to verify existing knowledge that current clinical coding practices lack standardised applications of regulatory guidelines. Method: Two medical records (cases 1 and 2) were provided to 15 clinical coders employed by a midsize nonprofit hospital in the northwest region of the United States. After coding these cases, the study participants completed a survey, reported on the application of guidelines, and participated in a focus group led by a health information management regulatory compliance expert. Results: Only 5 of the 15 clinical coders correctly indicated no POI complication in case 1 where the physician documentation did not establish a link between the POI as a complication of care and the surgery. In contrast, 13 of the 15 study participants correctly coded case 2, which included clear physician documentation and contained the clinical parameters for the coding of the POI as a complication of care. Clinical coder education, credentials, certifications, and experience did not relate to the coding performance. The clinical coders inconsistently prioritised coding rules and valued experience more than education. Conclusion and implications: The application of International Classification of Diseases, Ninth Revision, Clinical Modification; coding conventions; Centers for Medicare and Medicaid Services coding guidelines; and American Hospital Association coding clinic advice was subject to the clinical coders’ interpretation; they perceived them as conflicting guidance. Their reliance on subjective experience in dealing with this conflicting guidance may limit the accuracy of reporting outcomes of clinical performance.

Abstract:

In this paper, one-generator binary quasi-cyclic (QC) codes are explored by statistical tools derived from design of experiments. A connection between a structured cyclic class of statistical designs, k-circulant supersaturated designs and QC codes is given. The mathematical structure of the later codes is explored and a link between complementary dual binary QC codes and E(s2)-optimal k-circulant supersaturated designs is established. Moreover, binary QC codes of rate 1/3, 1/4, 1/5, 1/6 and 1/7 are found by utilizing a genetic algorithm. Our approach is based on a search for good or best codes that attain the current best-known lower bounds on the minimum distance of linear codes, formulated as a combinatorial optimization problem. Surveying previous results, it is shown, that our codes reach the current best-known lower bounds on the minimum distance of linear codes with the same parameters.

Abstract:

The flexible manipulator is widely used in space robots, robot arm, and manufacturing industries that produce micro-scale products. This study aims to formulate the equation of motion of a flexible single-link manipulator system that moves translationally and rotationally and to develop computational codes with finite element methods in performing dynamic simulation on the vibration of the flexible manipulator system. The system of the single-link flexible manipulator (SLFM) consists of the aluminum beam as a flexible link, clamp part to hold the link, DC motor to rotate drive shaft, a trajectory to transfer link in translational motion, and servo motor to rotate link. Computational codes in time history response (THR) and Fast Fourier Transform (FFT) processing were developed to identify the dynamic behavior of the link. The finite element-method and Newmark-beta are used in simulating the SLFM. Simulation using the finite element method has displayed dynamic behavior through a graph of FFT on free vibration and THR graph on forced vibration by the excitation force due to the translational and rotational motions of the system. In the simulation of free vibration, the natural frequency of the system is 8.3 [Hz].

Abstract:

In certain applications the user has to cope with some random packet erasures due, e.g., to deep fading conditions on wireless links, or to congestion on wired networks. In other applications, the user has to cope with a pure wireless link, in which all packets are available to him, even if seriously corrupted. The ARQ/FEC schemes already studied and presented in the literature are well optimized only for one of these two applications. In a previous work, the authors aimed at bridging this gap, giving a design method for obtaining hybrid ARQ schemes that perform well in both conditions, i.e., at the presence of packet erasures and packet fading. This scheme uses a channel coding system based on partially-systematic periodically punctured turbo codes. Since the computation of the transfer function and, consequently, the union bound on the Bit or Frame Error Rate of a partiallysystematic punctured turbo code becomes highly intensive as the interleaver size and the puncturing period increase, in this work a simplified and more efficient method to calculate the most significant terms of the average distance spectrum of the turbo encoder is proposed and validated.

Abstract:

In 1994 a squared two-dimensional barcode was invented by Toyota Company which changed and speed up the concept of tracking and identification. They chose its name QR which stands for Quick Response code. Quick Response codes can convey data such as show a geographical location, make a phone call, link to a simple text, link to a website or template email, access to a portable document format (PDF), display an image, link and download a specific application on a mobile device or Wi-Fi login. Academic journal leaders should notice that QR code as a unique shaped matrix code is increasingly being used by prestigious publishers and scientific journals. But has been ignored by eastern scientific journals and academic institutes for many years. As the author checked all English Iranian journals, no Iranian academic publication or publisher has and uses QR code or even barcode on their websites or on their journal covers till 16 Dec 2019. In this review, the author aimed to explore the use of QR codes specifically for academic publications, identify perceptions towards their use and any information that has been encountered during implementation.

Abstract:

This paper examines the link between the design codes, good design and the prevention of field failures. There are many design codes for the fatigue design of welds. They contain many differences influenced by the history of particular industries. Engineering may not be well served by these codes since on one hand they are normally conservative, thus creating excessively heavy structures. On the other hand the design codes often do not include the most important factors in the life expectancy of a weld namely the weld procedure, the quality of the weld and environmental effects. The paper concludes that a thorough review and unification of the industry design codes is overdue. The issue of manufacture of welds has to be put at the centre of the consideration of fatigue design.

Full text

Abstract:

Conventional neural networks try to solve the problem of object recognition in a single step by building a stimulus — response system that codes its result as cell activities. We take a different approach assuming that recognition is an active process with temporal dynamics and results in an ordered state. We present a structure of neuronal layers, interconnected by dynamic links (von der Malsburg, 1985 Berichte der Bunsengesellschaft für Physikalische Chemie89 703 – 710) that solves the correspondence problem between two images and thus constitutes an important building block for a model of recognition. Images as well as stored models are represented as Gabor pyramids. This allows the dynamics to proceed from coarse to fine scale and reduces the sequential processing time inherent in the concept. Invariance under background changes is also made possible. On the lowest frequency level, a single blob of activity moves across the image and model layer, respectively. Dynamic links between these layers are initialised to the (highly ambiguous) feature similarities. Links grow or decline according to a combination of feature similarity and correlated activation. This enforces correct neighbourhood relationships in addition to feature similarity. On the higher levels the established correspondences are refined by several blobs in parallel. We present an improved version of the dynamical system proposed by Würtz [1995 Multilayer Dynamic Link Networks for Establishing Image Point Correspondences and Visual Object Recognition (Thun, Frankfurt a.M.: Harri Deutsch)] and show, with examples of human faces, that it evolves from an unordered link distribution to any ordered state where only corresponding point pairs are connected by strong links. Correspondences between sample points are population-coded by a set of neighbouring links.

We define a generalization of virtual links to arbitrary dimensions by extending the geometric definition due to Carter et al. We show that many homotopy type invariants for classical links extend to invariants of virtual links. We also define generalizations of virtual link diagrams and Gauss codes to represent virtual links, and use such diagrams to construct a combinatorial biquandle invariant for virtual [Formula: see text]-links. In the case of [Formula: see text]-links, we also explore generalizations of Fox–Milnor movies to the virtual case. In addition, we discuss definitions extending the notion of welded links to higher dimensions.

Abstract:

The article describes an innovative method of volumetric assessment and certification of oil-contaminated land plots, which allows us to give an accurate assessment of the volume content of some limiting factors (in this work we considered such factors as oil pollution, chloride concentration and pH). This technique involves building 3D models, tabular systematization of concentrations and volumes of oil pollution, and improving the certification of the above-mentioned areas using special QR codes and parcel codes created by us. The method described by us makes it easier and at the same time increases the objectivity of certification of oil-contaminated land plots, reflects the qualitative and quantitative volume-time parameters of plots, increases the convenience, efficiency and reliability of accounting, data transmission and storage. To speed up the processing of information, we suggest using new forms of its representation (parcel codes). Parcel codes are an intermediate link for creating QR codes.

Abstract:

Abstract Medicare will continue to increase its efforts to cut spending through aggressive review of claims and the use of new fraud and abuse regulations. Providers must be especially careful to provide correct procedure codes that define precisely what services have been provided and accurate diagnosis codes that link those procedures or tests to an appropriate diagnosis. Medicare reimbursement rules for clinical laboratory procedures are explained, including the proper use of procedure and diagnosis codes. Coding and payment for new automated test panels are discussed, as well as the economic consequences of using smaller panels. Medicare coverage requirements, including medical necessity, are described, as well as the proper use of advance beneficiary notices and the Medicare appeals process.

Abstract:

There is justification for a simulation model for assessing channel level protocols. The effect of the data link layer protocol parameters on the data transfer function is analyzed. The data link protocol parameters have been specified and split into two categories, which are customizable and not configurable. In the work, parameters such as the acceptable information frame size are related in detail to the tunable data link protocol parameter; service personnel format; time-out value; unconfirmed frame window size, etc. That nominal data transfer rate, error-correcting codes used, etc. are non-configurable parameters.

Abstract:

One of the most difficult and under-examined issues in the ethics research of developing countries is whether the establishment of codes of ethics in public service organizations leads to employees’ organizational commitment. This study investigates the link between codes of ethics and organizational commitment, as well as its three dimensions of affective, normative and continuance commitment, in Ghanaian public service organizations. Correlational, regression and descriptive statistics were used to study 228 participants conveniently sampled from selected public service organizations within the Greater Accra Region of Ghana. Empirical evidence showed that codes of ethics significantly and positively predicted employees’ organizational commitment, as well as the three dimensions of the affective, normative and continuance commitment of employees. Points for practitioners Codes are intended to educate the general public, and employees in particular, about the mission of an organization, to foster a good ethical climate, and to provide guidance for resolving ethical problems in an organization. To ensure employee commitment to the organization, the codes should be effectively implemented, well communicated and strictly enforced with impartiality; otherwise, the codes will appear merely as ‘cosmetic dressing’ to the organization.

In this paper, our main objective is to find out the necessary and sufficient conditions for a cyclic code of arbitrary length over the ring of four elements [Formula: see text] [Formula: see text] to be a reversible cyclic code. We also obtain the structure of cyclic DNA codes of odd length over the ring [Formula: see text], which plays an important role in Computational Biology. Furthermore, we establish a direct link between the elements of ring [Formula: see text] and 64 codons used in the amino acids of living organisms by introducing a Gray map from [Formula: see text] to [Formula: see text]. Among others, binary images of cyclic codes over [Formula: see text] are also investigated. As applications, some cyclic DNA codes over [Formula: see text] using the Gray map are provided.

Abstract:

To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level – more abstract than that used to capture natural phenomena but less abstract than what is traditionally used to study high-level cognitive processes such as reasoning. At this “embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements.

Full text

Abstract:

Hearing and feeling both rely upon the transduction of physical events into frequency-based neural codes, suggesting that the auditory system may be intimately related to the somatosensory system. In this study, we provide evidence that the neural substrates for audition and somatosensation are anatomically linked. Using diffusion tensor imaging with both deterministic and probabilistic tractography to measure white matter connectivity, we show that there are extensive connections between the primary auditory cortex and the primary and secondary somatosensory regions in human cerebral cortex. We further show that these cross-connections are diminished between auditory and primary somatosensory cortex and exaggerated between auditory and secondary somatosensory cortex in the lesioned hemisphere of a patient (SR) with acquired auditory-tactile synesthesia, in whom sounds alone produce bodily sensations. These results provide an anatomical basis for multisensory interactions between audition and somatosensation and suggest that cross-talk between these regions may explain why some sounds, such as nails screeching down a chalkboard or an audible mosquito, can induce feelings of touch, especially on the left half of patient SR.

Abstract:

Abstract This text argues that a number of recent works of contemporary art have developed an anthropomorphised code to signal “humanness.” Primary within this code is representations of labour, which the artworks connect to mimetic or realist stylisation as well as to the history of image production and often specifically Western art-making. It elaborates this thesis with regards to recent videos by Pierre Huyghe and Sidsel Meineche Hansen, and at a critique of social media labour in a lecture-performance by Jesse Darling, which all draw a link between human and non-human subjectivities and economic productivity. In focusing on different examples of nonhuman likenesses, the text also uses primatology to suggest that the colonial relationship between labour and species and racial hierarchies continues to colour representations of labour today.

Abstract. The metric EISL (Equivalent Isotropic Sensitivity Level) describing the effective sensitivity level usable at the air interface of a mobile or a basestation is used to compare mobile communication systems either based on time division or code division multiple access in terms of coverage and emission characteristics. It turns out that systems that organize the multiple access by different codes rather than different timeslots run at less emission and offer greater coverage.

Abstract:

IntroductionStandard Occupational Classification (SOC) codes can link work exposure data to individual health outcomes, but manually assigning job codes is laborious. We tested two recently developed automatic coding programs.MethodsWe entered self-reported job titles and industry from two existing cohorts into two publicly available autocoding programs, the NIOSH Industry and Occupation Computerized Coding System (NIOCCS) and the Standardized Occupation Coding for Computer-assisted Epidemiological Research (SOCcer), and assessed agreement between autocodes and manual coding. We also assessed agreement of several exposure values (from the Occupational Information Network, O*NET) linked by manual SOC codes versus those linked by autocodes, in order to examine how differences in coding might affect exposure assignments in general population cohort studies.ResultsNIOCCS produced SOC codes for the majority of subjects (Cohort 1: 85%; Cohort 2: 79%). The level of detail for these codes varied slightly; 6-digit SOC codes (detailed occupations) were available for 84% and 76% of cohorts A and B respectively. Comparison to manual codes showed strong agreement at the major group level (kappa=0.8 for both cohorts) and weaker agreement at the 6-digit level (kappa ≥0.4 and 0.6). SOCcer produced 6-digit SOC codes for all subjects with good agreement at the 2-digit level (kappa ≥0.6 and 0.7) and slightly lower at the 6-digit level (kappa ≥0.3 and 0.4). Agreement for O*NET exposures was very high for most comparisons within both cohorts for both programs (many ICCs>0.8).ConclusionBoth autocoding programs can be reliable tools to aid in assigning SOC codes that represent broad industry levels, with less agreement at finer levels of job codes. Given the availability of large public datasets with job information but no other work exposure data, autocoding of jobs provides exciting opportunities for analyzing work-related health outcomes in future studies.

Abstract:

Voltage-gated calcium channels (VGCC) are key to many biological functions. Entry of Ca2+into cells is essential for initiating or modulating important processes such as secretion, cell motility, and gene transcription. In the retina and other neural tissues, one of the major roles of Ca2+-entry is to stimulate or regulate exocytosis of synaptic vesicles, without which synaptic transmission is impaired. This review will address the special properties of one L-type VGCC,CaV1.4, with particular emphasis on its role in transmission of visual signals from rod and cone photoreceptors (hereafter called “photoreceptors,” to the exclusion of intrinsically photoreceptive retinal ganglion cells) to the second-order retinal neurons, and the pathological effects of mutations in theCACNA1Fgene which codes for the pore-formingα1Fsubunit ofCaV1.4.

Abstract:

The v-akt oncogene codes for a 105-kilodalton fusion phosphoprotein containing Gag sequences at its amino terminus. Sequence analysis of v-akt and biochemical characterization of its product revealed that it codes for a protein kinase C-related serine-threonine kinase whose cellular homolog is expressed in most tissues, with the highest amount found in thymus. Although Akt is a serine-threonine kinase, part of its regulatory region is similar to the Src homology-2 domain, a structural motif characteristic of cytoplasmic tyrosine kinases that functions in protein-protein interactions. This suggests that Akt may form a functional link between tyrosine and serine-threonine phosphorylation pathways.

Abstract:

e24117 Background: The EORTC Item Library is an online, interactive platform comprised of 950 distinct questions (items) from 67 different EORTC patient-reported outcome (PRO) questionnaires, covering a range of symptomatic toxicities, types of functioning, and impact on quality of life. These PROs provide a patient-centred perspective, complementing clinician adverse event (AE) reporting using classifications like the CTCAE. In order to summarize the coverage of symptomatic toxicities and facilitate the identification of items through use of a standardized framework, a mapping study was carried out, aimed at creating a coding system to classify EORTC items according to the CTCAE and link them to corresponding AEs. Methods: All items were searched for within the CTCAE (v5.0) using a deductive approach. Items were coded as linked if they were described within an AE’s title, description, or grading. Items not suitable for CTCAE coding were inductively assigned a descriptive classification. Descriptive classifications were also applied along with CTCAE codes when they provided additional information. Symptoms described in EORTC items but not located in the CTCAE were coded as missing and additional codes were assigned to highlight EORTC items capturing multiple underlying issues and diagnosis only CTCAE codes. Two raters independently coded 249 items and agreement was calculated. The remaining 701 items were coded by one rater and verified by the second, with a third introduced to discuss any discrepancies until a consensus was reached. Results: Agreement for raters following independent coding was 77.9% for at least one AE per item. In total, 625 (65.8%) items were linked to 208 different AEs. Fatigue was the most commonly linked AE, representing 4.9% of linked AEs. The majority of linked items were associated with one (65.6%) or two (23.5%) AEs, with some linked to three or more (10.9%). Multiple linkage resulted from different symptoms relating to the same issue/diagnosis or one symptom relating to multiple diagnoses. Two symptoms captured by six EORTC items but not found in the CTCAE were identified: bowel urgency and tenesmus. Seven descriptive non-CTCAE classifications emerged, with most of these covering the emotional impact of symptom, diagnosis, or treatment (33.6%) and information/satisfaction with care (31.7%). Nineteen items (2%) were linked to multiple underlying issues, and 43 (4.5%) to diagnosis only CTCAE codes. Conclusions: The EORTC Item Library provides extensive coverage of CTCAE symptomatic toxicities, along with other issues that are important to cancer patients, including emotional well-being and satisfaction with care services. Classifying symptomatic PRO items following the CTCAE clinical framework may facilitate future PRO selection and use in clinical trials and routine care.

For links in eccentrically braced frames (EBFs), today’s design codes requirement of the flange width-thickness ratio is strict on high-strength steels, which eliminate a number of rolled wide-flange shape from use in EBFs. For this reason, building models using ANSYS program and control procedures for the previous tests to verify the correctness, and then design the specimens. This paper applies unidirectional load and cyclic load on the finite element models respectively. Through the calculation of the inelastic rotation which the link beams reach after the relaxation of the flange width-thickness ratio, the paper analyses the influences on the performance of the three tapes of links by the flange width-thickness ratio.

Abstract:

A classifier of QR-codes, which are used in light industry and are divided into static, dynamic, combined is developed in this work. Static QR codes can be digital, text or symbolic. Digital QR-codes are divided into subspecies: product code, product price, manufacturer code, date and other numerical designations. Text QR-codes are divided into subtypes: product name, product description, manufacturer and other text designations. Symbolic QR-codes are divided into subtypes: special symbols, formatting symbols and other marking symbols. Combined together, several types of QR codes form a combined code. Frequently static and dynamic QR codes are combined. Dynamic QR codes can only be combined. Based on the survey data, we can assume that the most important are the four main ways to use the QR-code are: “Outdoor advertising”, “Code on goods”, “Electronic ticket” and “Discount code”. Other ways to use a QR code, according to experts, have a much lower impact in terms of application. These include: “Invitation to social networks”, “Tourism”, “Banking”, “Company logo”, “Clothing and accessories”, “Tattoos”. This opinion of experts is typical only for Ukraine, because according to foreign studies, tattooing a QR-code on the human body is quite often met. Taking into account the results of the study, a label for products was made using a QR-code, which contains a link to the site TKSHV – Market. On the site it is possible to get acquainted in more detail with the products made at the department, to provide consumers with information about them. From the site it is possible to go to the Telegram-channel, where it is convenient to ask additional questions, see the process of creating a QR-code and more. It is also planned to create other channels on social networks, such as Instagram, Facebook, Viber. This will allow the consumer to use a more convenient social network.

Abstract:

AbstractThe present study intends to examine the link between clothes and cultural identities in Jhumpa Lahiri’s “Hema and Kaushik” (2008). It will argue that Lahiri explores her protagonists’ cultural displacement through their items of clothing. We want to suggest that the protagonists’ clothes are employed in each narrative as signifiers for the characters’ cultural identities. The study will further show that each item of clothing could be loaded with the ideological signification of two separate cultures. In other words, it aims to demonstrate how ideology imposes its values, beliefs, and consequently its dominance through the dress codes each defines for its subjects. Moreover, it intends to suggest that the link between clothing and identity is most visible and intense in the case of female immigrant characters rather than men. Drawing on Luptan’s structure of the Cinderella line, we will explore Lahiri’s protagonists’ cultural transformation from simple ethnic girls to stylish American ladies through their items of clothing. The study will conclude that the “Cinderella line” does not work in Lahiri’s realistic stories the way it does in fairy tales and romance fiction.
