CoLM2S: Contrastive self‐supervised learning on attributed multiplex graph network with multi‐scale information
Authors: Han Beibei , Wei Yingmei , Wang Qingyong , Wan Shanshan 
Published: February 2023

AbstractContrastive self‐supervised representation learning on attributed graph networks with Graph Neural Networks has attracted considerable research interest recently. However, there are still two challenges. First, most of the real‐word system are multiple relations, where entities are linked by different types of relations, and each relation is a view of the graph network. Second, the rich multi‐scale information (structure‐level and feature‐level) of the graph network can be seen as self‐supervised signals, which are not fully exploited. A novel contrastive self‐supervised representation learning framework on attributed multiplex graph networks with multi‐scale (named CoLM

S) information is presented in this study. It mainly contains two components: intra‐relation contrast learning and inter‐relation contrastive learning. Specifically, the contrastive self‐supervised representation learning framework on attributed single‐layer graph networks with multi‐scale information (CoLMS) framework with the graph convolutional network as encoder to capture the intra‐relation information with multi‐scale structure‐level and feature‐level self‐supervised signals is introduced first. The structure‐level information includes the edge structure and sub‐graph structure, and the feature‐level information represents the output of different graph convolutional layer. Second, according to the consensus assumption among inter‐relations, the CoLM2S framework is proposed to jointly learn various graph relations in attributed multiplex graph network to achieve global consensus node embedding. The proposed method can fully distil the graph information. Extensive experiments on unsupervised node clustering and graph visualisation tasks demonstrate the effectiveness of our methods, and it outperforms existing competitive baselines.
Accuracy analysis of farmer behaviour based on big data and efficient video transmission: A convolutional neural network approach
Authors: Qi Qi , Huo Hongmei 
Published: February 2023

AbstractThe behaviour analysis of farmers is very important to gradually improve the sustainable production capacity of the land and promote the economics reasonable increasement. How to effectively extract video features and identify human behaviour is a current research hotspot. In this paper, the authors propose a convolutional neural network model based on the deformable convolution including a residual module and an attention module. The model fuses and encodes video spatial features on the time axis and extracts semantic information. The authors combine the attention mechanism to extract local and global features in the video, which are used to calculate spatial features and micro‐motion features, respectively. Temporal attention mechanism fuses each micro‐motion feature of video to extract higher‐level semantic features of motion. Next, the authors describe their proposed model based on deep learning. First, the authors introduce a video frame sampling method based on the TRN algorithm. Second, they design a feature extraction and fusion model based on the ResNet model and the attention mechanism that extract local and global features in videos. Finally, the authors classify and identify the extracted video features through the classifier. The authors’ approach shows comparable performance on publicly available datasets.

Published: January 2023

AbstractA novel nanotextured Ni@Cu material embedded electro-microflow reactor with minimal electrode distance has been employed to synthesize biphenyls via the construction of a new C–C bond. The reported protocol is devoid of noble metals and involves co-reductant/oxidant-free conditions in a fast manner for the synthesis of substituted/unsubstituted biphenyl systems. The electro-reactor volume was optimized for gram-scale biphenyl synthesis and further extended for an integrated total process system reducing the tedious downstream process by selective removal of unwanted chemicals/solvent. The continuous microflow synthesis of daclatasvir has now been accomplished with a good yield.
Investigating the Mechanism of the Catalytic Intramolecular Aza-Wittig Reaction Involved in the Synthesis of 2-Methylbenzothiazole from the Perspective of Bonding Evolution Theory
Authors: Adjieufack Abel Idrice , Champagne Benoît , Liégeois Vincent 
Published: January 2023

AbstractBonding evolution theory has been used at the density functional theory level [ωB97X-D exchange-correlation functional, 6-311G(d,p) basis set, and solvent (toluene) effects with polarizable continuum model] to unravel the reaction mechanism of the intramolecular aza-Wittig reaction of 2-(acetylthio)phenyl isocyanate (1) catalyzed by 3-methyl-1-phenyl-2-phospholene 1-oxide (2) to form 2-methylbenzothiazole (3). The reaction involves four steps (transition states) corresponding to (1) the formation of a cycloadduct (O–C then P–N bonds), (2) a decarboxylation leading to the formation of an iminophosphorane, and (3) an intramolecular [2+2] cycloaddition (N–C then P–O bonds) followed by (4) a retro [2+2] cycloaddition (cleavage of the P–N then O–C bonds) to get the product and regenerate the catalyst. Step 1 is the rate-determining step with an activation Gibbs free enthalpy of 21 kcal mol–1 and it is favored with respect to a competitive pathway leading to the formation of another cycloadduct (P–C then O–N bonds). The whole reaction is exergonic with a Gibbs free energy decrease of 31 kcal mol–1, associated with the liberation of a CO2 molecule and the formation of the aromatic benzothiazole. Following the scale of Domingo, the successive steps of the reaction have a polar nature.

Abstract
Objectives The aim of this study was to determine the value of immune expression of p63 and cyclin D1 in the prediction of lymphovascular invasion (LVI) and perineural invasion (PNI) in oral squamous cell carcinoma (OSCC).
Materials and Methods Clinical and histopathologic features of 65 subjects with histologically confirmed OSCC were collected. Tissue microarray blocks representing all subjects were prepared for the immunohistochemical quantification of the nuclear expression of p63 and cyclin D1 using immune ratio plugin of image J software. Image analysis was performed by two independent pathologists. Independent samples t-test, analysis of variance, and receiver operating characteristic curve tests were used for statistical analysis. The level of significance was set at p≤ 0.05.
Results The optimum cutoff value for the prediction of LVI for p63 and cyclin D1 was found to be 100 and 93.2, respectively, while the optimum cutoff value for the prediction of PNI for p63 and cyclin D1 was found to be 95.9 and 94, respectively. p63 and cyclin D1 expression correlated with several clinicopathologic features of the studied population. p63 expression was a significant predictor of moderate/poorly differentiated OSCC compared with well-differentiated OSCC. A parallel combination of positive p63 and cyclin D1 increased the specificity of predicting LVI from 89.1% and 67.4% for either p63 or cyclin D1, respectively, to 93.5% with a positive predictive value of 92.5%. Similarly, the parallel combination of the two markers raised the specificity of predicting PNI from 70% and 77.5% for either p63 or cyclin D1, respectively, to 90% with a positive predictive value of 86.3%.
Conclusion Combined overexpression of nuclear markers p63 and cyclin D1 can be considered as a valuable independent predictor of LVI and PNI, and hence tumor progression, in OSCC.
Neoadjuvant Treatment for Rectal Cancer and Nonoperative Management/Total Neoadjuvant Therapy
Authors: Edwards-Murphy Amy , Neary Peter 
Published: February 2023

AbstractTreatment of locally advanced rectal cancer remains one of the most challenging in colorectal surgery. It has had an evolving landscape over the past three decades. This review describes the introduction of total neoadjuvant therapy—a term aimed to describe an approach where both systemic chemotherapy and chemoradiation are administered in the preoperative setting. This novel strategy has come to the fore with the strength of well-documented results of recent trials. Its implementation has begun globally, but long-term outcomes and data analysis to identify optimal schedules are eagerly awaited.
Evaluation of the i10-Index in Plastic Surgery Research and its Correlation with Altmetric Attention Scores and Traditional Author Bibliometrics: An Evaluation of a Single Journal
Authors: Shiah Eric , Heiman Adee J. , Ricci Joseph A. 
Published: February 2023

Abstract
Background Although the Hirsch index (H-index) has become one of the most accepted measures of scholarly output, its limitations have led to the proposition of newer alternative metrics. The i10-index, notable for being easy to calculate and free to access, has potential, given its association with the power and ubiquity of Google. This study aims to evaluate the utility of the i10-index for plastic surgery research by examining its relationship with author bibliometrics and article metrics, including the H-index and Altmetric Attention Score (AAS).
Methods Article metrics were extracted from articles published in the highest impact plastic surgery journal, Plastic and Reconstructive Surgery, over a 2-year period (2017–2019). Senior author bibliometrics, including i10-index and H5-index, were obtained from Web of Science. Correlation analysis was performed using Spearman's rank correlation coefficient (rs).
Results A total of 1,668 articles were published and 971 included. Senior author i10-index measurements demonstrated moderate correlation with times emailed (rs = 0.47), and weak correlations with H5-index, total publications, and sum of times cited with and without self-citations. The H5-index correlated very strongly with total publications (rs = 0.91) and sum of times cited (both rs = 0.97), moderately with average citations per item (rs = 0.66) and times emailed (rs = 0.41), and weakly with number of citations by posts, AAS, and times tweeted.
Conclusions Although the i10 strongly correlates with the H5-index, it fails to prove superior to the H5-index in predicting the impact of specific research studies in the field of plastic surgery.
Definition, Documentation, and Classification of Complications in Pediatric Surgical Literature—A Plea for Standardization
Authors: Madadi-Sanjani Omid , Brendel Julia , Kuebler Joachim F. , Ure Benno M. 
Published: January 2023

AbstractSeverity grading systems for complications in surgical patients have been used since 1992. An increasing assessment of these instruments in pediatric surgery is also noticed, without their validation in children. To analyze the current practice, we performed a literature review with focus on the assessment and grading of complications. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies reporting on postoperative complications as a primary or secondary endpoint using a severity grading system were included. Definition for simple adverse events, classification systems used, and the time horizon of postoperative documentation were analyzed. A total of 566 articles were screened, of which 36 met the inclusion criteria. About 86.1% of the papers were retrospective and 13.9% prospective analyses. None of the studies were prospective-randomized trials. Twenty (55.6%) studies did not include a definition of adverse events, whereas the remaining 16 (44.4%) showed variations in their definitions. All studies applied the Clavien-Dindo classification, whereas five (13.9%) additionally used the Comprehensive Complication Index. One study compared alternative grading instruments with the Clavien-Dindo classification, without demonstrating the superiority of any classification in pediatric surgery. Twenty-two studies (61.1%) did not report the time horizon of perioperative complication documentation, while 8 studies (22.2%) used 30 days and 6 studies (16.7%) used 3 months of postoperative documentation. Definition and classification of postoperative complications are inconsistent in the pediatric surgical literature. Establishment of a standardized protocol is mandatory to accurately compare outcome data.

Published: January 2023

AbstractIntroduction In the health care environment, a huge volume of data is produced on a daily basis. However, the processes of collecting, storing, sharing, analyzing, and reporting health data usually face with numerous challenges that lead to producing incomplete, inaccurate, and untimely data. As a result, data quality issues have received more attention than before.Objective The purpose of this article is to provide an insight into the data quality definitions, dimensions, and assessment methodologies.Methods In this article, a scoping literature review approach was used to describe and summarize the main concepts related to data quality and data quality assessment methodologies. Search terms were selected to find the relevant articles published between January 1, 2012 and September 31, 2022. The retrieved articles were then reviewed and the results were reported narratively.Results In total, 23 papers were included in the study. According to the results, data quality dimensions were various and different methodologies were used to assess them. Most studies used quantitative methods to measure data quality dimensions either in paper-based or computer-based medical records. Only two studies investigated respondents' opinions about data quality.Conclusion In health care, high-quality data not only are important for patient care, but also are vital for improving quality of health care services and better decision making. Therefore, using technical and nontechnical solutions as well as constant assessment and supervision is suggested to improve data quality.
A vibrational action spectroscopic study of the Renner–Teller- and spin–orbit-affected cyanoacetylene radical cation HC3N+

Published: January 2023

The linear radical cation of cyanoacetylene, HC3N+ (2Π), is not only of astrophysical interest, being the, so far undetected, cationic counterpart of the abundant cyanoaceteylene, but also of fundamental spectroscopic interest due to its strong spin–orbit and Renner–Teller interactions. Here, we present the first broadband vibrational action spectroscopic investigation of this ion through the infrared pre-dissociation (IRPD) method using a Ne tag. Experiments have been performed using the FELion cryogenic ion-trap instrument in combination with the FELIX free-electron lasers and a Laservision optical parametric oscillator/optical parametric amplifier system. The vibronic splitting patterns of the three interacting bending modes (ν5, ν6, ν7), ranging from 180 to 1600 cm−1, could be fully resolved revealing several bands that were previously unobserved. The associated Renner–Teller and intermode coupling constants have been determined by fitting an effective Hamiltonian to the experimental data, and the obtained spectroscopic constants are in reasonable agreement with previous photoelectron spectroscopy (PES) studies and ab initio calculations on the HC3N+ ion. The influence of the attached Ne atom on the infrared spectrum has been investigated by ab initio calculations at the RCCSD(T)-F12a level of theory, which strongly indicates that the discrepancies between the IRPD and PES data are a result of the effects of the Ne attachment.
Explicitness and implicitness of discourse relations in a multilingual discourse bank
Authors: Mendes Amália , Zeyrek Deniz , Oles̆kevic̆ienė Giedrė 
Published: January 2023

Abstract
Proposals such as continuity and causality-by-default relate the level of expectedness of a relation to its
linguistic marking as an explicit or implicit relation. We investigate these two proposals with regard to the English transcripts
of six TED Talks and their Lithuanian, Portuguese and Turkish translations in the TED-Multilingual Discourse Bank (TED-MDB),
annotated for discourse relations, following the Penn Discourse Treebank style of annotation. Our data shows that the
discontinuous relations contrast and concession are indeed frequently explicit in all languages. But continuous
relations show differences per relation and language. For instance, cause is frequently conveyed implicitly in English
and Portuguese, but not in Lithuanian and Turkish. We explore temporal continuity by analysing whether the forward-order sense
result is more frequently implicit than the backward-order reason. The hypothesis is confirmed by English
and Portuguese, but not Lithuanian and Turkish. However, in Turkish, the arguments of the backward-order relation reason
are frequently presented by the reversed order of arguments, retaining the linear order of events even in the presence of the
connective. The causality-by-default hypothesis is not confirmed, as cause is not the most frequent implicit relation in
the four languages.
Continuity in discourse relations
Authors: Das Debopam , Egg Markus 
Published: January 2023

Abstract
Continuity and discontinuity (maintaining or shifting deictic centres across segments) are important aspects of
discourse relations. Yet they have been attributed to these relations in very different ways. This calls for an analysis of
individual instances of discourse relations with respect to their continuity dimensions. To this end, we operationalise Givón’s (1993) continuity dimensions (time, space, reference, action,
perspective, modality, and speech act), decomposing them into distinctive features that allow a
consistent and accurate classification of the continuity dimensions in discourse relation tokens. This inventory was applied to
five representative relation types (causal, contrastive, conditional, elaboration, and
temporal) from the RST Discourse Treebank (Carlson & Marcu 2001). We
found that relations can simultaneously be more continuous for some dimensions but more discontinuous for others. What is more,
discourse relations typically vary widely in different continuity dimensions and thus cannot be described as fully continuous or
discontinuous, neither on the level of the entire relation type nor for one of its particular dimensions. Using examples of
causal, conditional, and contrastive relations, we also illustrate how the results of our analysis
can be used to verify hypotheses about correlations between continuity and discourse relations.

AbstractReadingis a unique interactional practice in the drag queen community. It refers to leveling witty and often cutthroat mock insults at fellow drag queens, with an aim ofthrowing shade. In this paper, I examine the discourse of the ‘reading challenge’, a staple ofRuPaul’s Drag Race(RPDR), an internationally popular drag queen reality TV show (2009–). In the first part, I review central concepts surrounding drag performance and the phenomenon ofRPDRand summarize relevant sociolinguistic literature about drag queen speech and the practice ofreading. In the second part, I describe theRPDR reading challengeas a unique discursive genre and analyse its performative structure, themes, and most prominent strategies that queens use to construct felicitous reads and throw shade. The analysis demonstrates that this genre relies on camp language and highly ritualized, repetitive, and recontextualized performance of reading, framed by requirements of mass-consumed reality TV.
Mathematics, relevance theory and the situated cognition paradigm
Authors: McCallum Kate 
Published: February 2023

AbstractMathematics is a highly specialised arena of human endeavour, one in which complex notations are invented and are subjected to complex and involved manipulations in the course of everyday work. What part do these writing practices play in mathematical communication, and how can we understand their use in the mathematical world in relation to theories of communication and cognition? To answer this, I examine in detail an excerpt from a research meeting in which communicative board-writing practices can be observed, and attempt to explain the observed exchanges with reference to relevance theory (a cognitivist theory of pragmatics), in combination with the situated cognition paradigm. Successful communication in the excerpt appears well described by the notion of metacognitive acquaintance, as described inSperber & Wilson (2015), especially when a situated view of cognition is adopted. Though this example is taken from a relatively informal face-to-face communicative situation, characteristics of such situations extend even into formal written mathematics, since even the technical terminology developed in the course of the meeting includes details that may provide readers with a kind of access to the mathematicians’ cognitive processes.

AbstractParticipation in experimental studies can be conceptualized as Goffmanian frames, i.e. a set of rules which include the fact the experimenter will be observing participant behavior through (the recording of) the experiment. This study is focused on frame breaches in 16 video- and audio-recorded dyadic conversations taking place in an experimental setting. Our main conclusion is that the experimental frame is conceptualized by participants as including constraints that go beyond non-experimental interactions, and in particular the need to mitigate frame breaches, which are seen as face-threatening. Analyses revealed that participants only broke the research frame after they completed the task they were assigned by the researcher, and that breaches did not necessarily correspond to changes in key. Insights gained in relation to face and mitigation are discussed, as well as the participants’ need to determine their next steps once the research purpose has been perceived complete.
