Abstract:
Abstract This article presents the results of a study in which students in a graduate translation technologies course post-edited a text they had previously translated earlier in the semester without using machine translation (MT). The results show that post-editing allowed students with performance levels below, at, and just above an established median to improve the quality of their translation products, while students with performances well above the median actually experienced a decrease in quality. Nevertheless, the post-edited products and post-editing performances of the latter remained superior to those of the former. The study shows how different translators experienced gains or not in quality by accepting different aspects of MT output and how the accepted output relates to their human renditions. It also tracks whether their post-edits were necessary and correct and how they relate to their human renditions. Tracking such behaviors attempts to provide a more holistic view of how post-editing might be qualitatively advantageous or disadvantageous.

Abstract:
Many approaches have recently been proposed to detect irregular scene text and achieved promising results. However, their localization results may not well satisfy the following text recognition part mainly because of two reasons: 1) recognizing arbitrary shaped text is still a challenging task, and 2) prevalent non-trainable pipeline strategies between text detection and text recognition will lead to suboptimal performances. To handle this incompatibility problem, in this paper we propose an end-to-end trainable text spotting approach named Text Perceptron. Concretely, Text Perceptron first employs an efficient segmentation-based text detector that learns the latent text reading order and boundary information. Then a novel Shape Transform Module (abbr. STM) is designed to transform the detected feature regions into regular morphologies without extra parameters. It unites text detection and the following recognition part into a whole framework, and helps the whole network achieve global optimization. Experiments show that our method achieves competitive performance on two standard text benchmarks, i.e., ICDAR 2013 and ICDAR 2015, and also obviously outperforms existing methods on irregular text benchmarks SCUT-CTW1500 and Total-Text.

Abstract:
While the difference between a dramatic production and a literary text is obvious in theory, the distinction blurs when we attempt to enfold historical performances into theatre history. For we, lacking personal encounter with a long-past performance's signifiers or its audience reception, are left with no alternative other than to explore that event in terms of its still-extant literary text. This barrier remains to be overcome by those who would canonize any particular theatrical Performance.

Full text
Abstract:
Integrated speaking tasks requiring test takers to read and/or listen to stimulus texts and to incorporate their content into oral performances are now used in large-scale, high-stakes tests, including the TOEFL iBT. These tasks require test takers to identify, select, and combine relevant source text information to recognize key relationships between source text ideas, and to organize and transform information. Despite being central to evaluations of validity, relationships between stimulus content, task demands, and the oral discourse produced by test takers are yet to be empirically scrutinized to an adequate degree. In this study, we focus on a TOEFL iBT reading–listening–speaking task, applying discourse analytic measures developed by Frost, Elder and Wigglesworth (2012) to 120 oral performances to examine (a) the integration of source text ideas by test takers across three proficiency levels, and (b) the appropriateness of content-related criteria in the TOEFL integrated speaking rubric. We then combine analyses of these aspects of performances with a qualitative analysis of the generic structure and semantic profiles of stimulus texts to explore relationships between stimulus text properties and oral performances. Findings suggest that the extent to which content-related rating scale criteria distinguish between proficiency levels is contingent on stimulus text properties, with important implications for construct definitions and task design.

Full text
Abstract:
If written texts usually involve some kind of performative dimension, oral performances also entail the constitution of a text. American linguistic anthropology uses the term ‘entextualization’ for the process by which stretches of spoken discourse are detached from their immediate context and rendered repeatable and thus transmissible. In African oral poetry there are entextualizing strategies which involve rendering discourse object-like: by making it the focus of exegesis, or by presenting it as quotable, thus foregrounding the perception that these words pre-existed their present moment of utterance and could continue to exist after it. However, African oral praise poetry is also highly dynamic. Text is not consolidated in order to constitute it as an unchanging monument, but rather so that it can be re-activated in a new context of utterance, where it has an effectual engagement and dialogic force. Thus the performative and the entextualizing dimension can be seen to be inseparable and mutually dependent.

Abstract:
This study investigates the effect of different unit cells on the mechanical performance of porous implant. Three shapes of unit cells (Diamond 30(DO30), Octet truss 30(OT30), and Rhombic dodecahedron 30(RD30)) were selected, which have the same relative density. Corresponding models of single pore (SP), repeating pores (RP) and porous implant (PI) were created. Using finite element methodology, mechanical performances of three classes of models under the conditions of pressure and torsion were simulated based on the same static load (SP: 50[Formula: see text]N, 0.125[Formula: see text]N[Formula: see text]m; RP: 200[Formula: see text]N, 0.5[Formula: see text]N[Formula: see text]m; PI: 200[Formula: see text]N, 0.5[Formula: see text]N[Formula: see text]m), respectively. Results demonstrated that RP showed consistent mechanical performances with SP: OT30 displayed the lowest stresses, displacements, and strains under the conditions of pressure and torsion, and conversely DO30 always resulted in the highest magnitudes. For the case of PI, mechanical performances were different from SP and RP: implant with shape of RD30 resulted in the lowest stress (275.2[Formula: see text]MPa) under the condition of pressure, but displacement (2.236e[Formula: see text]002[Formula: see text]mm) and strain (3.050e[Formula: see text]003) of OT30 were the largest; under the condition of torsion, stress sequence was same as SP and RP, but DO30 provided the highest strain (2.437e[Formula: see text]003), RD30 displayed the largest displacement (1.508e[Formula: see text]002[Formula: see text]mm). Unit cell influences mechanical performance of porous implant directly, and the implant outline and incomplete structure may also affect it. It could not select pore simply by the right type of unit cell, and surface area is an important parameter as well as pore size.

Abstract:
Based in anthropology (Cole & Knowles, 2001), life history inquiry into literature emphasizes deep understandings of literary characters that are expressed through dramatic performance. For teachers or teacher-educators, life histories offer a powerful teaching strategy. Life histories support locating readers in a particular pattern or “grammar” of events, situations, and goals while also revealing the subjective worlds of characters who are involved in such events. In an undergraduate Honors Literacies course, life histories performances in response to the young adult novel, The Skin I’m In(Flake, 1998), enabled examinations of the complex interaction of characters, their lives, and particular contexts.

Through the focus of historical inquiry into the monthly performances of Austin Ballet Theatre in Austin, Texas, a local amateur company, at the Armadillo World Headquarters, a psychedelic and “outlaw country” music hall, from 1972–1980, this paper explores an example of dance phenomena surviving outside of normative discursive support through the textual mediation provided by specific newspaper reviewers. The frequency and unique nature of these ballet performances created the circumstances that generated a more open, reciprocal, and diachronic conversation between the participants involving dance and text—a conversation that generated functioning narratives of identity.

Abstract:
Human Computer Interaction (HCI) researches the use of computer technology mainly focused on the interfaces between human users and computers. Expression of emotion comprises of challenging style as it is produced with plaint text and short messaging language as well. This research paper investigates on the overview of emotion recognition from various texts and expresses the emotion detection methodologies applying Machine Learning Approach (MLA). This paper recommends resolving the problem of feature meagerness, and largely improving the emotion recognition presentation from short texts by achieving the three aims: (I) The representing short texts along with word cluster features, (II) Presenting a narrative word clustering algorithm, and (iii) Making use of a new feature weighting scheme of the Emotion classification. Experiments were performed for the classifying the emotions with different features and weighting schemes, on the openly available dataset. We have used the word clusters in place of unigrams as features, the micro-averages of accuracy have been found to be enhanced by more than three percentage, which suggests that the overall accuracy value of the text emotion classifier has been improved. All the macro-averages were enhanced by more than one percentage, which suggests that the word cluster feature can advance the generalization potential of the emotion classifier. The experimental results suggest that the text words cluster features and the proposed weighting scheme can moderately resolve the problems of the emotion recognition performance and the feature sparseness.

Full text
Abstract:
The paper deals with different forms of the performance text, still a new phenomenon in contemporary theatre, which requires new instruments for its analysis. The structural transformation of the written text into the performance, including the role of the spectator in it, confirms the fact that the performance text does not simply mean a new kind of the written text – and even less a new type of theatre text, but rather an essentially changed hypertext. Instead, the performance text could also be called an open text of the performance, in the sense that it requires spectators to become its active co-writers. Can we, therefore, define the performance text as a scenic écriture, collective writing, hypertext, stretch text, or even écriture corporelle? Furthermore, how can it be translated from stage to page to be preserved for future studies? The performance text is impossible without its author(s). Therefore, the paper deals with the performances of The Wooster Group, Motus, René Pollesch, Joris Lacoste, Milo Rau and Oliver Frljić, who are all constantly producing performance texts with their actors, without separating the process of writing from directing.

Abstract:
Steganography is one of the categories in information hiding that is implemented to conceal the hidden message to ensure it cannot be recognized by human vision. This paper focuses on steganography implementation in text domain namely text steganography. Text steganography consists of two groups, which are word-rule based and feature-based techniques. This paper analysed these two categories of text steganography based on effectiveness and security evaluation because the effectiveness is critically important in order to determine that technique has the appropriate quality. Meanwhile, the security is important due to the intensity performance in securing the hidden message. The main goal of this paper is to review the evaluation of text steganography in terms of effectiveness and security that have been developed by previous research efforts. It is anticipated that this paper will identify the performance of text steganography based on effectiveness and security measurement.

Abstract:
As part of growing efforts to understand factors affecting c-test this study aims to investigate the effect of text authenticity on the performance of Iranian EFL students in a C-Test. The C-Test is an integrative testing instrument that measures overall language competence, very much like the cloze test. In this study the rule of two has been applied: “the second half of every second word has been deleted, beginning with the second word of the second sentence; the first and last sentences are left intact” (Katona and Dornyei 1993: 35). The research involves 60 college students in their third year, majoring in English Literature at Ershad-Damavand College. This group were randomly selected applying multi-stage sampling. Since the present study intended to investigate the role of two different formats, i.e. authentic and inauthentic texts (text translated from Persian into English), two different tailored C-Tests were made to measure and compare the performances of the participants. Two C-Tests, one with Authentic Text and the other, with Inauthentic Text were administered to this homogenized group comprising 30 subjects. The findings of this study suggest that authenticity has an effect on the performance of learners in c-tests and we should control this variable while devising a c-test.

The electrochemical performances of Y-NiOHS with difference Y-doped mole ratios (Y:[Formula: see text]%, 0.5%, 1%Y-NiOHS) were characterized by cyclic voltammetry (CV), constant current charge–discharge test (GCD) and AC impedance test (EIS). The results of CV show that 0.5%Y-NiOHS in 5[Formula: see text]mV/s scan rate can achieve the maximum capacity of 320.92[Formula: see text]F/g. The results of GCD show that the capacity of 0.5%Y-NiOHS is 226.2[Formula: see text]F/g at 0.5[Formula: see text]A/g discharge current density and the 1000 charge–discharge cycles after the capacitance retention rate is 85%. The electrochemical performance of 0.5%Y-NiOHS are better than NiOHS and NiO powder.

Full text
Abstract:
This article addresses the key role of performance space in mediating between cultural locations. It discusses two Portuguese performances of Shakespeare where audiences were invited to become part of the performance and the ways in which this dehierarchization of the performance space framed a cross-cultural encounter between a globalized text and a localized performance context. In Teatro Oficina’s 2012 King Lear, both audience and performers sat around a large table in a production which reflected upon questions of individual and collective responsibility in Shakespearean tragedy and in the wider political sphere. In the middle of this performance space hung a large cube onto which the translated text was projected, setting up a spatial tension between text and performance that also foregrounded the translocation of the Shakespearean text to a Portuguese performance context. In Tiago Rodrigues’ 2013 By Heart, ten members of the audience were invited onstage to learn Shakespeare’s Sonnet 30 “by heart and not by brain.”1 In doing so, Rodrigues emphasized the cultural embeddedness of Shakespearean texts in a wider European cultural context and operated a subtle shift from texts to performance as a privileged repository for the cultural memory of Shakespeare. The article explores how these spatial shifts signaled the possibility of enabling cross-cultural identifications with Shakespeare through performance.

Abstract:
Objectives: This study will evaluate the results of parameters measured during a treadmill exercise test to predict marathon performances. Methods: We studied 171 Chinese recreational athletes who participated in marathons or half-marathons (42.2[Formula: see text]k or 21.1[Formula: see text]k, respectively) between October 2016 and December 2017. The participants completed a survey that included questions about demographics and training, and they underwent a treadmill exercise test according to the Bruce protocol. The number of years in training, mean weekly hours of training, mean weekly training volume, and performance time in subsequent marathon events were recorded and analyzed in this study. Results: The total exercise times achieved on the treadmill test were significantly longer for men compared to women ([Formula: see text]). The performance times in the half-marathons were significantly shorter for men compared to women ([Formula: see text]). Training volume was the only independent predictor of total exercise time on the treadmill and performance time in marathons and half-marathons (all [Formula: see text]). The value of the total exercise time on the treadmill to predict performance times in half-marathons ([Formula: see text]) was superior to full marathons ([Formula: see text]) and significantly better in study subjects aged 30–39 years ([Formula: see text], [Formula: see text]) and 40–49 years ([Formula: see text], [Formula: see text]) compared to study subjects aged 20–29 years and 50–59 years. The percentage of decrease in the maximal heart rate (MHR) at the end of one minute of recovery time was negatively correlated with performance times in marathons. Conclusions: The total exercise time achieved during an exhaustive treadmill exercise test and percentage of decrease in the MHR at the end of one minute of recovery time are accessible parameters that can help athletes manage their expectations and adjust their training plans. A large study that includes additional countries is needed to confirm the value of treadmill exercise test results for predicting marathon performance.

Abstract:
Enhancing the catalytic activity of manganese oxide in oxygen reduction reaction (ORR) is a key issue for its large-scale application in metal-air fuel cells. Ag-doped [Formula: see text]-MnO2 nanowires without Ag or Ag2O have been successfully synthesized via a facile hydrothermal method, and the changes in both the structure and electrochemical catalytic performances after Ag doping are investigated. Compared with the pristine [Formula: see text]-MnO2, the as-prepared Ag-doped MnO2 exhibits a significantly enhanced catalytic activity in both ORR and Mg-air fuel cell application. With Ag/Mn ratio of 1:25, Ag-doped MnO2 exhibits a typical 4e-reaction pathway and presents a 163 mV higher half-wave potential than that of the pristine [Formula: see text]-MnO2. Furthermore, it demonstrates a power density of 75.1[Formula: see text]mW[Formula: see text]cm[Formula: see text] at current density of 134.5[Formula: see text]mA[Formula: see text]cm[Formula: see text] in the Mg-air fuel cells. The enhanced ORR performances are considered to be contributed from the activation of surface lattice oxygen, the improvement in conductivity and the increase in oxygen vacancies of [Formula: see text]-MnO2. These findings provide new understanding for developing high-performance manganese oxide catalysts.

Electrodes of rationally designed composite nanostructures can offer many opportunities for the enhanced performance in electrochemical energy storage. This paper attempts to illustrate the design and production of NiMoO4/polypyrrole core–shell nanostructures on nickel foam to be used in supercapacitor via a facile hydrothermal and electrodeposition process. It has been verified that this novel nanoscale morphology has outstanding capacitive performances. While employed as electrodes in supercapacitors, the composite nanostructures showed remarkable electrochemical performances with a great areal capacitance (3.2[Formula: see text]F/cm2 at a current density of 5[Formula: see text]mA/cm2), and a significant cycle stability (80% capacitance retention after 1000 cycles). The above results reveal that the composite nanostructures may be a likely electrode material for high-performance electrochemical capacitors.

Abstract:
The paper focuses on poetry-based video performances conducted by the participants of the “Creative Youths Seminar” (CYS), which was founded in 1995. Adaptability is one of the most essential features of all seminar clusters. It leads to constant transformations in a general program and within poetry performance laboratory (existing as a part of CYS since 2015) in particular, due to socio-cultural and political context. In 2020, because of the quarantine restrictions, CYS for the first time changed its regular face-to-face form to a remoteone and took place online. Live performance cluster transformed into a three-day marathon of video performances. During that time 24 participants made over 70 video performances that lasted for more than 100 minutes in total (there was a record number in every category of a CYS performance cluster). Nearly half of the performances were poetry-based. Almost a third part was based on the poems by Ukrainian Futurist writers Oleksa Vlyzko, Mykhail Semenko, Oleksa Slisarenko, Andrii Chuzhyi, Geo Shkurupii, and Yulian Shpol. The article analyzes five poetry-based video performances that refer to the poems by Geo Shkurupii as pretexts: “A Talk with a Future Self ” by Yaroslav Boruta, “I Want to Be a Furniture” by Vladyslava Demianchuk (Dadi), “Oh Little Boy” by Natalia Matsybok-Starodub, “Czech Scotch Tape” by Iryna Pavlenko (Ira Pamiatai), and “The Future of Cherry Orchards” by Viktoriia Feshchuk. The pretexts, poetry performance texts (if any), and their intermedial connections with video performances have been examined. The researcher concludes that poetry-based performances let the artists not only experience the text traditionally but also ‘live through the text’, or, in other words, create a personal physical experience of the pretext and offer the audience another perspective on the pretext with the help of non-literary media.

Meanwhile, three-dimensional graphene networks (3DGNs) are employed to provide a fast transport channel for photo-induced electrons. The morphology is analyzed by SEM, TEM, XRD and Raman spectrum, and the photovoltaic performances are recorded to reveal the specific functions of MOF and 3DGNs. The synergy between MOF, 3DGNs and TiO2 is achieved by adjusting their mass fraction. Moreover, the average size of MOF exerts a significant influence on the resulting properties resulting from the scattering ability to incident light. After corresponding optimizing, the short circuit current, open circuit voltaic, fill factor and energy conversion efficiency reach 20.5[Formula: see text]mAcm[Formula: see text], 680[Formula: see text]mV, 0.619% and 8.63%.

Abstract:
The relationships between verbal and mathematical performances were examined in 60 children (26 girls and 34 boys, mean age = 9.1 yr, SD = 0.3) for scores on standard school tests. Scores for numerical problem solving appeared to correlate mainly with verbal performances such as text comprehension ( r = 0.65, p < .05) and knowledge of vocabulary ( r = 0.61, p < .05) among linguistic performances. Such results suggest that the dichotomy between verbal and numerical cognitive abilities, commonly involved in pedagogical approaches, is an ambiguous notion for the analysis of problem-solving performance.

This Introduction to a special issue on “The Sacramental Text Reconsidered” provides a brief genealogy of the practice of describing texts, performances, and poetics as sacramental, eucharistic, and incarnational. It also offers a critique and clarification of such reading practices by differentiating between the real divine presence theologically understood to dwell in a proper sacrament and the “disincarnation” enacted by sacramentally laden literary texts and performances. Drawing on the writings of Emmanuel Levinas, Rowan Williams, and St. Paul, I demonstrate the disincarnate as a poetic of ritual and oblation in an extended reading of Herbert’s poetry.

Abstract:
Science texts use various text features and multiple representations to communicate meaning to their readers. English science texts are challenging for elementary-level English as a foreign language (EFL) learners in Taiwan because they are familiar with reading language-controlled texts from textbooks. Teaching students to make use of various text features and visual representations will help them achieve a more successful science text reading experience. In this study, 27 Grade 6 Taiwanese students were instructed in science text reading strategies that included understanding text features, creating imagery, and using visual representations. Before and after the instruction, they took an English reading and writing test. Their eye movements during science text reading were recorded before and after the instruction to more fully understand their visual attention while reading English science texts. Eye movement performances such as number of fixations, mean fixation duration, and saccade size were examined. The findings showed that although the participants’ English reading and writing performance improved in the post-test, they focussed more on the written language than the visuals in both tests. More visual representation reading strategies should therefore be taught to help young EFL students read and learn from science texts.

Abstract:
AbstractThis article presents silhouette–attraction (Sil–Att), a simple and effective method for text clustering, which is based on two main concepts: the silhouette coefficient and the idea of attraction. The combination of both principles allows us to obtain a general technique that can be used either as a boosting method, which improves results of other clustering algorithms, or as an independent clustering algorithm. The experimental work shows that Sil–Att is able to obtain high-quality results on text corpora with very different characteristics. Furthermore, its stable performance on all the considered corpora is indicative that it is a very robust method. This is a very interesting positive aspect of Sil–Att with respect to the other algorithms used in the experiments, whose performances heavily depend on specific characteristics of the corpora being considered.

Supplementary Run Rules are applied to increase the power of the standard Shewhart [Formula: see text] chart for detecting small shift. The performance of this chart is usually evaluated under the assumption of known parameters. However, in practice, the process parameters are rarely known and, usually estimated from an in-control Phase I data set. In this paper, we evaluate (using a Markov Chain model) the performances of the Run Rules [Formula: see text] chart when the process parameters are estimated, and compare them when the process parameters are assumed known. We draw the conclusion that these performances are quite different when the number of samples used during the phase I is small and we suggest new chart parameters in order to overcome this problem.

Effects of reaction times (2–8[Formula: see text]h) on crystallinity and electrochemical performances of Fe3O4 were investigated. Samples were analyzed by X-ray diffraction, infrared spectroscopy, N2 adsorption–desorption, scanning electron microscope, galvanostatic charge/discharge, and cyclic voltammetry. Results showed that the crystallinity of Fe3O4 was increased with hydrothermal time, and the sample prepared at 2[Formula: see text]h displayed amorphous structure with small grain size and large surface area of 165.0[Formula: see text]m2[Formula: see text]g[Formula: see text]. The sample exhibited typical pseudocapacitive behavior with capacitance of 383.2[Formula: see text]F[Formula: see text]g[Formula: see text] at 0.5 Ag[Formula: see text] in Na2SO3 electrolyte. After 2000 cycles, the capacitance retention of Fe3O4 at 2[Formula: see text]h was recorded as 83.6%, much higher than 26.3% for sample at 8[Formula: see text]h. It indicated that hydrothermal method was an effective approach to obtain amorphous Fe3O4, implying the potential application for preparing metal oxide electrode for supercapacitors.

Abstract:
Nature language inference (NLI) task is a predictive task of determining the inference relationship of a pair of natural language sentences. With the increasing popularity of NLI, many state-of-the-art predictive models have been proposed with impressive performances. However, several works have noticed the statistical irregularities in the collected NLI data set that may result in an over-estimated performance of these models and proposed remedies. In this paper, we further investigate the statistical irregularities, what we refer as confounding factors, of the NLI data sets. With the belief that some NLI labels should preserve under swapping operations, we propose a simple yet effective way (swapping the two text fragments) of evaluating the NLI predictive models that naturally mitigate the observed problems. Further, we continue to train the predictive models with our swapping manner and propose to use the deviation of the model’s evaluation performances under different percentages of training text fragments to be swapped to describe the robustness of a predictive model. Our evaluation metrics leads to some interesting understandings of recent published NLI methods. Finally, we also apply the swapping operation on NLI models to see the effectiveness of this straightforward method in mitigating the confounding factor problems in training generic sentence embeddings for other NLP transfer tasks.

Abstract:
This paper deals with the corporeality of a performance and its place in the process of the emergence of meaning, following a case study of a Serbian theatrical piece Vox Dei – Civil Disobedience. Performance is constituted by bodies brought together by a certain purpose and temporal and spatial coordinates, and it is more and more often now decoded by the feedback loop performers and participants form in specific kinds of spatiality. Artistic corporeality defies objectivization, therefore the relational aesthetics is needed instead of an idealistic one to investigate the materiality of these performances. Using this theoretical framework, the analysis of the two different performances of the same dramatic text from the recent Serbian political theater production will tend to examine the nature of political potential of bodily co-presence in artistically and socially different environments and its implications for the semioticity of the given embodied text.

Abstract:
Nowadays, dealing with imbalanced data represents a great challenge in data mining as well as in machine learning task. In this investigation, we are interested in the problem of class imbalance in Authorship Attribution (AA) task, with specific application on Arabic text data. This article proposes a new hybrid approach based on Principal Components Analysis (PCA) and Synthetic Minority Over-sampling Technique (SMOTE), which considerably improve the performances of authorship attribution on imbalanced data. The used dataset contains 7 Arabic books written by 7 different scholars, which are segmented into text segments of the same size, with an average length of 2900 words per text. The obtained results of our experiments show that the proposed approach using the SMO-SVM classifier, presents high performance in terms of authorship attribution accuracy (100%), especially with starting character-bigrams. In addition, the proposed method appears quite interesting by improving the AA performances in imbalanced datasets, mainly with function words.

We found that Br incorporation in an I/Cl-based structure dramatically improved the charge transport within the perovskite layer. The average efficiency of the planar device was 13.6% with a minimal standard deviation of [Formula: see text] 1.53% and best efficiency as high as 15.13% was achieved. Moreover, the device showed superior stability over 20 days with little degradation [Formula: see text]9% when stored under ambient conditions, indicating the outstanding performances of planar heterojunction solar cells based on this material.

Abstract:
In recent years, Deep Learning methods have become very popular in classification tasks for Natural Language Processing (NLP); this is mainly due to their ability to reach high performances by relying on very simple input representations, i.e., raw tokens. One of the drawbacks of deep architectures is the large amount of annotated data required for an effective training. Usually, in Machine Learning this problem is mitigated by the usage of semi-supervised methods or, more recently, by using Transfer Learning, in the context of deep architectures. One recent promising method to enable semi-supervised learning in deep architectures has been formalized within Semi-Supervised Generative Adversarial Networks (SS-GANs) in the context of Computer Vision. In this paper, we adopt the SS-GAN framework to enable semi-supervised learning in the context of NLP. We demonstrate how an SS-GAN can boost the performances of simple architectures when operating in expressive low-dimensional embeddings; these are derived by combining the unsupervised approximation of linguistic Reproducing Kernel Hilbert Spaces and the so-called Universal Sentence Encoders. We experimentally evaluate the proposed approach over a semantic classification task, i.e., Question Classification, by considering different sizes of training material and different numbers of target classes. By applying such adversarial schema to a simple Multi-Layer Perceptron, a classifier trained over a subset derived from 1% of the original training material achieves 92% of accuracy. Moreover, when considering a complex classification schema, e.g., involving 50 classes, the proposed method outperforms state-of-the-art alternatives such as BERT.

Abstract:
Fabrication of Nanogenerators (NGs) using Electrospun polyvinylidene fluoride (PVDF) nanofibers for sensing and energy harvesting applications is a trending research due to its flexibility, biocompatibility, low-cost, etc. Different electrode materials, polymer composites had been proposed to increase the energy output. However, the contact area between the electrode material and nanofiber mat which helps to conduct more piezoelectric charges to the electrode surface are still unexplored especially at nanoscale level. In this paper, authors have proposed the use of low-cost carbon conductive paint to increase the contact area between the electrode and nanofiber mat. The electrode material is coated with conductive paint and the NG was fabricated with that electrode to compare the performances with conventional NG. Piezoelectric performance of the proposed NG has increased substantially as it generates an open circuit voltage [Formula: see text]) of 4.5[Formula: see text]V and short circuit current [Formula: see text]) of 25[Formula: see text]nA, whereas the conventional NG can only produce 1.6 [Formula: see text]) and 1.5[Formula: see text]nA [Formula: see text]).

This paper presents the design of a 60[Formula: see text]GHz-band LNA intended for the 63.72–65.88[Formula: see text]GHz frequency range (channel-4 of the 60[Formula: see text]GHz band). The LNA is designed in a 65-nm CMOS technology and the design methodology is based on a constant-current-density biasing scheme. Prior to designing the LNA, a detailed investigation into the transistor and passives performances at millimeter-wave (MMW) frequencies is carried out. It is shown that biasing the transistors for an optimum noise figure performance does not degrade their power gain significantly. Furthermore, three potential inductive transmission line candidates, based on coplanar waveguide (CPW) and microstrip line (MSL) structures, have been considered to realize the MMW interconnects. Electromagnetic (EM) simulations have been performed to design and compare the performances of these inductive lines. It is shown that the inductive quality factor of a CPW-based inductive transmission line ([Formula: see text] is more than 3.4 times higher than its MSL counterpart @ 65[Formula: see text]GHz. A CPW structure, with an optimized ground-equalizing metal strip density to achieve the highest inductive quality factor, is therefore a preferred choice for the design of MMW interconnects, compared to an MSL. The LNA achieves a measured forward gain of [Formula: see text][Formula: see text]dB with good input and output impedance matching of better than [Formula: see text][Formula: see text]dB in the desired frequency range. Covering a chip area of 1256[Formula: see text][Formula: see text]m[Formula: see text]m including the pads, the LNA dissipates a power of only 16.2[Formula: see text]mW.

Abstract:
LaFeO3/NiO modified g-C3N4 nanosheets (L-N/CNS) were synthesized by a two-step method. HRTEM results showed that an intimate contact between LaFeO3, NiO and N-CNS was successfully established. Ninety percent of phenol was degraded within 120[Formula: see text]min, and the hydrogen evolution rate of 171.2[Formula: see text][Formula: see text]mol[Formula: see text]h[Formula: see text][Formula: see text]g[Formula: see text] was obtained over the L-N/CNS heterojunctions under the visible-light irradiation. It was higher than that of g-C3N4 nanosheets, NiO modified g-C3N4 and LaFeO3/g-C3N4. The[Formula: see text][Formula: see text][Formula: see text]O[Formula: see text] radicals acted the crucial role in the photocatalytic degradation reaction. EIS, PL and time-resolved fluorescence spectra demonstrated that L-N/CNS possessed the highest charge separation efficiency. The intimate contact between LaFeO3, NiO and g-C3N4 nanosheets promoted the separation and transfer of photo-induced electron–hole pairs and consequently prolonged the exciton lifetime, and implied more photo-induced electrons could be probably involved in the photocatalytic reactions on the surface of photocatalysts. Thus, the visible-light driven photocatalytic performances of L-N/CNS were effective. This work provided a feasible method to design and construct heterostructures for the exploitation of solar energy.

Results showed that regardless of the subjects' prior training and experience, the most efficient and effective task performances were obtained through a combination of audio and graphics media; an effect which can be further enhanced by the addition of redundant task instructions in textual form. The practical applications and theoretical implications of these findings are discussed.

Interlinked carbon nanoflakes have dual roles not only as a highly conductive matrix to host sulfur, but also act as blocking barriers to suppress the shuttle effect of intermediate polysulfides.

Abstract:
Abstract Taking off from the Media Talk approach, this paper examines the communicative work of a Swedish sports webcast football show, Superlive, as an emerging form of web-based media format called Web-TV. This analysis is situated in a context in which broadcasting is going through fundamental changes, and broadcasters are rethinking their content in order to face the challenges arriving with recent decades’ technological developments, and especially the fact that television is no longer restricted to being broadcast but can be distributed through the web and be received on PCs, tablets and mobile phones. In this ‘post-broadcasting era’ producers are searching for new ways of reaching audiences through creating new forms of audience address. Superlive is a good example of these changes and how broadcasters now explore the possibilities of producing television exclusively for the Web. The analysis shows that what is taking place in Superlive is clearly in contrast to the performances one could expect in the conventional broadcast. Through the participants’ favoring of an interactional style characterized by informality and spontaneity, this show situates itself as backstage to the conventional forms of airings. As a result, this discursive space implies an interactional orientation to “co-presence” with the audience.

Abstract:
A series of Ag3PO4/BiOCOOH composite photocatalysts have been successfully synthesized by a simple in situ ion precipitation method. The crystallinity, morphology, microstructure, composition and optical property were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), energy dispersive spectrum (EDS), Fourier transform infrared spectrometer (FT-IR), X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance spectrophotometer (DRS). The as-prepared catalysts exhibited excellent photocatalytic activity for the degradation of RhB and MB under visible light irradiation, the 2:1 Ag3PO4/BiOCOOH exhibited the best photocatalytic activity. By adding different free radical scavengers, the catalytic mechanism was discussed. In the process of degradation of RhB, holes (h[Formula: see text] is the main active species, [Formula: see text]O[Formula: see text] played a certain active role, [Formula: see text]OH played a small role. In the process of degradation MB, holes (h[Formula: see text] is the main active species too, [Formula: see text]O[Formula: see text] also played a certain active role, [Formula: see text]OH almost does not work.

Abstract:
The task of summarization can be categorized into two methods, extractive and abstractive. Extractive summarization selects the salient sentences from the original document to form a summary while abstractive summarization interprets the original document and generates the summary in its own words. The task of generating a summary, whether extractive or abstractive, has been studied with different approaches in the literature, including statistical-, graph-, and deep learning-based approaches. Deep learning has achieved promising performances in comparison to the classical approaches, and with the advancement of different neural architectures such as the attention network (commonly known as the transformer), there are potential areas of improvement for the summarization task. The introduction of transformer architecture and its encoder model “BERT” produced an improved performance in downstream tasks in NLP. BERT is a bidirectional encoder representation from a transformer modeled as a stack of encoders. There are different sizes for BERT, such as BERT-base with 12 encoders and BERT-larger with 24 encoders, but we focus on the BERT-base for the purpose of this study. The objective of this paper is to produce a study on the performance of variants of BERT-based models on text summarization through a series of experiments, and propose “SqueezeBERTSum”, a trained summarization model fine-tuned with the SqueezeBERT encoder variant, which achieved competitive ROUGE scores retaining the BERTSum baseline model performance by 98%, with 49% fewer trainable parameters.

Abstract:
The defects induced by a spike rapid thermal annealing (RTA) process in crystalline silicon (c-Si) solar cells were investigated by the photoluminescence (PL) technique and the transmission electron microscopy (TEM), respectively. Dislocation defects were found to form in the near-surface junction region of the monocrystalline Si solar cell after a spike RTA process was performed at 1100[Formula: see text]C. Photo J–V characteristics were measured on the Si solar cell before and after the spike RTA treatments to reveal the effects of defects on the Si cell performances. In addition, the Silvaco device simulation program was used to study the effects of defects density on the cell performances by fitting the experimental data of RTA-treated cells. The results demonstrate that there was an obvious degradation in the Si solar cell performances when the defect density after the spike RTA treatment was above [Formula: see text][Formula: see text]cm[Formula: see text].
