Where do Clinical Language Models Break Down? A Critical Behavioural Exploration of the ClinicalBERT Deep Transformer Model
Authors: MacLean Alexander , Wong Alexander
Published: February 2021

The introduction of Bidirectional Encoder Representations from Transformers (BERT) was a major breakthrough for transfer learning in natural language processing, enabling state-of-the-art performance across a large variety of complex language understanding tasks. In the realm of clinical language modeling, the advent of BERT led to the creation of ClinicalBERT, a state-of-the-art deep transformer model pretrained on a wealth of patient clinical notes to facilitate for downstream predictive tasks in the clinical domain. While ClinicalBERT has been widely leveraged by the research community as the foundation for building clinical domain-specific predictive models given its overall improved performance in the Medical Natural Language inference (MedNLI) challenge compared to the seminal BERT model, the fine-grained behaviour and intricacies of this popular clinical language model has not been well-studied. Without this deeper understanding, it is very challenging to understand where ClinicalBERT does well given its additional exposure to clinical knowledge, where it doesn't, and where it can be improved in a meaningful manner. Motivated to garner a deeper understanding, this study presents a critical behaviour exploration of the ClinicalBERT deep transformer model using MedNLI challenge dataset to better understanding the following intricacies: 1) decision-making similarities between ClinicalBERT and BERT (leverage a new metric we introduce called Model Alignment), 2) where ClinicalBERT holds advantages over BERT given its clinical knowledge exposure, and 3) where ClinicalBERT struggles when compared to BERT. The insights gained about the behaviour of ClinicalBERT will help guide towards new directions for designing and training clinical language models in a way that not only addresses the remaining gaps and facilitates for further improvements in clinical language understanding performance, but also highlights the limitation and boundaries of use for such models.
Seeing the Forest from the Trees: A Novel Deep Learning-Driven Aggregate Embedding for Group-Level Analysis of Public Health Data
Authors: MacLean Alexander , Yang Yang , Chen Helen , Wong Alexander
Published: February 2021

In the years since the COMPASS dataset initiative was begun, many important research questions have been investigated using its large amount of health information pertaining to high school students across Canada, with findings guiding many decisions made by policy makers [1]. However, to use traditional statistical methods, specific data points must be selected by researchers to include in the analysis, leading to possible unexpected relationships and connections across the study's 280 data points being missed. As well, most analysis is done on a per-student basis, while policies are often implemented at the school level, so understanding behaviours across a school's population can make it easier for school decision makers to interpret findings. Motivated by these goals, this study introduces a novel deep learning-driven aggregate embedding method to determine group-level representations for individual schools from student-level survey responses based on architecture introduced in Variational Autoencoders [2]. This study aims to produce a method which allows for new patterns to be identified in the COMPASS data and for the resulting embedded representations to be applied in future analysis.
Temporally Consistent Edge-Informed Video Super-Resolution (Edge-VSR)
Authors: Singh Ayush , Ebrahimi Mehran
Published: February 2021

Resolution enhancement of a given video sequence is known as video super-resolution. We propose an end-to-end trainable video super-resolution method as an extension of the recently developed edge-informed single image super-resolution algorithm. A two-stage adversarial-based convolutional neural network that incorporates temporal information along with the current frame's structural information will be used. The edge information in each frame along with optical flow technique for motion estimation among frames will be applied. Promising results on validation datasets will be presented.
Rectification Based Single-Shot Structured Light for Accurate and Dense 3D Reconstruction
Authors: Farsangi Sina , Naiel Mohamed A. , Lamm Mark , Fieguth Paul
Published: February 2021

Structured Light (SL) patterns generated based on pseudo-random arrays are widely used for single-shot 3D reconstruction using projector-camera systems. These SL images consist of a set of tags with different appearances, where these patterns will be projected on a target surface, then captured by a camera and decoded. The precision of localizing these tags from captured camera images affects the quality of the pixel-correspondences between the projector and the camera, and consequently that of the derived 3D shape. In this paper, we incorporate a quadrilateral representation for the detected SL tags that allows the construction of robust and accurate pixel-correspondences and the application of a spatial rectification module that leads to high tag classification accuracy. When applying the proposed method to single-shot 3D reconstruction, we show the effectiveness of this method over a baseline in estimating denser and more accurate 3D point-clouds.
Constraints for Time-Multiplexed Structured Light with a Hand-held Camera
Authors: Ghavam Sepehr , Post Matthew , Naiel Mohamed A. , Lamm Mark , Fieguth Paul
Published: February 2021

Multi-frame structured light in projector-camera systems affords high-density and non-contact methods of 3D surface reconstruction. However, they have strict setup constraints which can become expensive and time-consuming. Here, we investigate the conditions under which a projective homography can be used to compensate for small perturbations in pose caused by a hand-held camera. We synthesize data using a pinhole camera model and use it to determine the average 2D reprojection error per point correspondence. This error map is grouped into regions with specified upper-bounds to classify which regions produce sufficiently minimal error to be considered feasible for a structured-light projector-camera system with a hand-held camera. Empirical results demonstrate that a sub-pixel reprojection accuracy is achievable with a feasible geometric constraints
Evaluation of Solving Methods for the Fundamental Matrix Computation
Authors: Arnold Katherine , Naiel Mohamed A. , Lamm Mark , Fieguth Paul
Published: February 2021

Solving the fundamental matrix is a key step in many image calibration and 3D reconstruction systems. The goal of this paper is to study the performance of non-linear solvers for estimating the fundamental matrix in projector-camera calibration. To prevent measurements errors from distorting our understanding, synthetic data are created from ground-truth camera and projector parameters and then used for the assessment of four nonlinear solving strategies.
A 2-Level Iterated Tabu Search Algorithm for the Quadratic Assignment Problem
Authors: Misevičius Alfonsas , Kuznecovaitė (Verenė) Dovilė
Published: February 2021

In this paper, a 2-level iterated tabu search (ITS) algorithm for the solution of the quadratic assignment problem (QAP) is considered. The novelty of the proposed ITS algorithm is that the solution mutation procedures are incorporated within the algorithm, which enable to diversify the search process and eliminate the search stagnation, thus increasing the algorithm’s efficiency. In the computational experiments, the algorithm is examined with various implemented variants of the mutation procedures using the QAP test (sample) instances from the library of the QAP instances – QAPLIB. The results of these experiments demonstrate how the different mutation procedures affect and possibly improve the overall performance of the ITS algorithm.

Various diseases, such as glaucoma, hypertension, diabetic retinopathy, macular degeneration, etc., can be diagnosed by changes and anomalies of vesssels and optical disk. For semantic segmentation convolutional neural networks, especially U-Net architecture, are well suited. Recently a number of U-Net modifications have been developed that deliver excellent performance results.
Developmental and family considerations in internet use disorder taxonomy. Commentary on: How to overcome taxonomical problems in the study of Internet use disorders and what to do with “smartphone addiction”? (Montag et al., 2020)
Authors: Browne Dillon T. , May Shealyn S. , Colucci Laura , Rumpf Hans-Jurgen
Published: February 2021

Montag, Wegmann, Sariyska, Demetrovics, and Brand (2019) propose an important framework surrounding the taxonomy of problematic internet usage, with particular applications to disentangling the role of mobile and other handheld devices versus stationary platforms. This is a critical contribution, as organizational frameworks have begun to move past “whether” there is disordered internet use, and towards better understanding the complex and multifaceted ways in which internet usage can be related to psychological maladjustment. In the present commentary, we encourage authors to extend this framework by incorporating developmental complexities. Montag and colleagues' (2019) contribution is discussed with reference to children and families, including: (1) the conceptualization of problematic internet usage and associated behaviors across the early years, (2) the types of internet use and devices that are most salient for young users, (3) the embedding of children's internet consumption within the context of a broader pattern of family media usage, and (4) the construct of behavioral addictions in pediatric populations. Recommendations for science and practice are briefly discussed.

Background and aims

Some online gamers may encounter difficulties in controlling their gaming behavior. Previous studies have demonstrated beneficial effects of transcranial direct current stimulation (tDCS) on various kinds of addiction. This study investigated the effects of tDCS on addictive behavior and regional cerebral metabolic rate of glucose (rCMRglu) in problematic online gamers.

Methods

Problematic online gamers were randomized and received 12 sessions of either active (n = 13) or sham tDCS (n = 13) to the dorsolateral prefrontal cortex over 4 weeks (anode F3/cathode F4, 2 mA for 30 min, 3 sessions per week). Participants underwent brain 18F-fluoro-2-deoxyglucose positron emission tomography scans and completed questionnaires including the Internet Addiction Test (IAT), Brief Self-Control Scale (BSCS), and Behavioral Inhibition System/Behavioral Activation System scales (BIS/BAS) at the baseline and 4-week follow-up.

Results

Significant decreases in time spent on gaming (P = 0.005), BIS (P = 0.03), BAS-fun seeking (P = 0.04), and BAS-reward responsiveness (P = 0.01), and increases in BSCS (P = 0.03) were found in the active tDCS group, while decreases in IAT were shown in both groups (P < 0.001). Group-by-time interaction effects were not significant for these measures. Increases in BSCS scores were correlated with decreases in IAT scores in the active group (β = −0.85, P < 0.001). rCMRglu in the left putamen, pallidum, and insula was increased in the active group compared to the sham group (P for interaction < 0.001).

Discussion and conclusions

tDCS may be beneficial for problematic online gaming potentially through changes in self-control, motivation, and striatal/insular metabolism. Further larger studies with longer follow-up period are warranted to confirm our findings.

Logoterapia e Teologia: uma hipótese autotranscendente para o aconselhamento pastoral junto às pessoas com tendências suicidas
Authors: Da Silva Vardilei Ribeiro , De Paula Blanches
Published: February 2021

As diferenças sociais, o desemprego, os preconceitos, a violência e tantas outras questões afetam as mais diferentes pessoas e as afetam de maneiras diferentes, tendo em vista a singularidade de cada um. É nessa sociedade complexa que o Aconselhamento Pastoral se apresenta como campo de atuação para pastoras, pastores, leigas e leigos juntamente as pessoas que sofrem e se deparam com o vazio existencial. Apesar da sua relevância, o Aconselhamento Pastoral como uma das áreas da Teologia Prática, carece de maiores subsídios para lidar com o ser humano em crise e em especial aqueles que constantemente são afligidos pelas ideações suicidas. A logoterapia se apresenta, nesse sentido, como área de conhecimento que em sua epistemologia oferece significativas contribuições para a Teologia.
Anjos, Demônios e Transtornos Mentais: os desafios do aconselhamento pastoral no contexto Pentecostal
Authors: Herbes Nilton Eliseu , Da Silva Borges Dainel
Published: February 2021

Este artigo tem por objetivo analisar alguns dos principais fatores empíricos encontrados no axioma dos transtornos mentais. Ele busca expor a respeito das dificuldades do Aconselhamento Pastoral no contexto Pentecostal. Este trabalho é fruto de uma investigação bibliográfica e qualitativa disponível na internet nos últimos 16 anos. Como critérios de busca foi estabelecido dois filtros para esta seleção: o primeiro por meio da indicação do termo em questão, e o segundo por palavras que indicam a temática no resumo dos artigos. A partir da análise e leituras consultadas foi possível apontar que: no Brasil, existe um avanço dos transtornos mentais, ao mesmo tempo que uma eclosão Pentecostal. Isso lança questões a respeito de como podemos ter uma visão mais holística para as dificuldades inerentes às questões da saúde mental no Aconselhamento Pastoral no âmbito das comunidades Pentecostais. No contexto Pentecostal, há grandes dificuldades de a pessoa receber orientação eficaz quando o Aconselhamento se aproxima dos transtornos mentais. Olhando o ser humano de forma holística, a saúde do ser humano vai encontrar integralidade em todas as áreas da sua vida, seja ela física, espiritual e da sua alma.

Published: February 2021

The article is devoted to the analysis and evaluation of mechanisms of ecological and economic regulation of railway transport in the conditions of technological development in the interests of their improvement. It is indicated that Russia has developed a system of methods of environmental and economic regulation of railway transport. Attention is drawn to the insufficient effectiveness and efficiency of the current system of environmental and economic regulation mechanisms to encourage railway transport entities to technological modernization. The authors indicate the need to develop a comprehensive approach to the analysis and evaluation of mechanisms, taking into account their interdependence, dependence on internal and external factors, risks of technological development of the transport industry, and the impact of each mechanism on the environment. The article proposes to analyze and evaluate the mechanisms of environmental and economic regulation of railway transport based on the analysis and assessment of their contribution to the goals and objectives of state environmental policy at all levels (national, regional, industry, object). To analyze and evaluate the mechanisms of environmental and economic regulation of railway transport in the interests of implementing the state environmental policy in the context of technological development, an algorithm and indicator for analysis and evaluation are proposed. The authors draw attention to an important element of the analysis and evaluation of the mechanisms of environmental and economic regulation of railway transport-an assessment of the environmental and economic effects of the introduction and use of mechanisms. An algorithm and indicator for evaluating the integral ecological and economic effect of the introduction and use of mechanisms of ecological and economic regulation of railway transport are proposed. The proposed approach is aimed at improving the system of mechanisms for environmental and economic regulation of railway transport, taking into account the environmental imperative of technological development of the economy. The article is based on the results of research work on the topic No. 7280-20 «Improving the mechanisms of environmental and economic regulation of the turnover of fecal waste of railway transport», performed by the authors in 2020.

Mobile cross-platform app development tools
Authors: Nedyak Anton , Rudzeyt Oleg , Zainetdinov Artem , Ragulin Petr
Published: February 2021

This article discusses the existing popular tools for mobile cross-platform application development. It is contrasted with the so – called native application development-when applications are created using the tools provided by the development companies of the respective platforms. Google provides a tool like Android Studio for its Android mobile operating system. The main programming languages used to create applications for this platform are Java and Kotlin. Apple, in turn, offers developers such an integrated development environment as XCode, in which development is carried out using the Swift programming language. The authors reviewed some of the most popular tools for cross-platform development, such as React Native, Xamarin and Flutter. React Native is a product developed by the company Facebook. It inherits the main technological aspects from another framework from Facebook-React. Programming here is conducted in the JavaScript language. React Native is suitable for web developers who have worked with React before and now want to try their hand at developing mobile applications. Xamarin is a framework supported by Microsoft. It provides tools for creating cross-platform applications for the iOS and Android mobile operating systems. This framework is bundled with Microsoft Visual Studio as a downloadable component. What is typical for a Microsoft product, here the C# programming language is used for development. This is a significant advantage of the Xamarin framework: during the creation of a mobile application, developers can use all the important and convenient features of this programming language. Flutter is a tool developed by Google to create apps for Android and iOS using a single code base. Unlike other popular solutions, Flutter is not a framework: it is a set of software development tools that contains everything you need to create cross-platform applications. It includes a visualization engine, ready-made widgets, and tools for working with the command line. The main programming language here is Dart. In the course of studying these tools, the authors made the following conclusions: tools for cross-platform development are an excellent solution if you need to create an application that does not require high performance: displaying information received from the server, simple local information processors, such as applications for social networks, online stores, organizer applications. These tools are not suitable for creating applications that require computing resources.
Yield and profitability of flooded rice genotypes in relation to nitrogen doses and phosphorus and potassium application

Published: February 2021

ABSTRACT The use of hybrid genotypes is a good alternative for increasing the flooded rice yield. However, there is a need for validation of the fertilizer management under different edaphoclimatic conditions and its greater profitability. This study aimed to evaluate the grain yield and profitability of rice hybrids in relation to N doses and fertilization with P and K. Five hybrid cultivars and the conventional IRGA 424 CL cultivar combined with four N doses (0, 100, 150 and 200 kg ha-1) were evaluated, all with fixed doses of 90 kg ha-1 of P2O5 and 150 kg ha-1 of K2O, besides an additional treatment without the addition of fertilizers. The N application increases, on average, by 10 and 35 % the flooded rice yield in years with favorable and unfavorable climatic conditions, respectively. Regardless of the year and genotype, the highest yields are obtained with doses of N between 106 and 200 kg ha-1, with the most profitable dose being the 150 kg ha-1 one (22 % higher than for the absence of N). The hybrids produce an average of 20 % more grains than the IRGA 424 CL cultivar, increasing the profitability by 18 %. In soil with adequate P and K availability, there is no increase in yield due to the application of these nutrients. However, in deficient soil, the fertilization with P and K increases the grain yield by 21 %.

Published: February 2021

ABSTRACT The bur gherkin cultivation is predominantly carried out without a staking system, but problems such as the "white belly" and fruit rot occur in this system. This study aimed to evaluate staking systems for bur gherkin plants. The experimental design was randomized blocks, with five treatments (no staking, agricultural netting staking, Mexican staking, vertical ribbon with total secondary stem thinning and vertical ribbon with alternate secondary stem thinning) and four replicates. The fresh mass and number of fruits per plant, fruit length and average diameter, number and fresh mass of fruits with white belly per plant, fresh mass per fruit and total yield were evaluated, as well as the economic indicators gross income, net income, rate of return and profitability index. For all the staking systems, the incidence of fruits with white belly was lower. The agricultural netting (43.75 t ha-1), Mexican (35.94 t ha-1) and vertical ribbon with alternate secondary stem thinning (22.24 t ha-1) systems promoted yields superior to that for no staking. The best economic indicator (US$ 21,031.46 ha-1) was observed for the agricultural netting staking, which is the most recommended for the bur gherkin cultivation.

Abstract Livestock in the Amazon has grown significantly and, although neosporosis in cattle has been reported worldwide, there is no information about N. caninum in production systems in the state of Amazonas. The objective of this study was to determine the prevalence of anti-Neospora caninum antibodies in cattle, their spatial distribution and the risk factors associated with N. caninum infection in the state of Amazonas. Questionnaires were applied to farmers to assess risk factors associated with N. caninum infection. Blood samples were collected from 1,073 animals on 47 farms in 33 municipalities in the four Amazonian subpopulations. IgG anti-N.caninum antibodies were detected by the indirect fluorescence test, with a general prevalence of 30.2%, being seropositive in 43 farms (91.5%), with prevalence ranging from 2.2% to 69.2%. The highest number of high density points was found in subpopulation 3 (municipality of Apuí and other municipalities on the Madeira River and affluent). It was concluded that N. caninum is present with high seroprevalence values, when compared to other cattle producing states in the Amazon region of Brazil. The identified factors can be used as risk indicators so that control measures can be implemented to prevent infection by N. caninum in these herds.

Abstract Visceral leishmaniasis is a widely distributed zoonosis and canine infection is an important indicator of risk for the occurrence of the disease in humans. The goal of this analysis was to study the spatial clustering of canine leishmaniasis (CL) in the municipality of Santa Luzia, state of Paraíba. For this, 749 samples of canine plasma were tested using three serological tests. The dog was considered positive if it reacted in two serological tests. The location of the residences was performed with a Global Positioning System receiver (GPS Garmin® eTrex 30), and used to perform georeferencing and spatial analysis. The prevalence of CL was 15.49% and it was observed that most cases of the urban area were concentrated in the Frei Damião neighborhood, on the outskirts of the city, where a high-risk cluster for the occurrence of the disease was formed (p = 0.02; RR = 2.48). No statistically significant cluster was observed in rural areas. CL is widely distributed in the municipality of Santa Luzia in a heterogeneous manner and with a tendency to urbanization. The areas identified with high prevalence and highest risk should be prioritized to maximize the efficiency of the Visceral Leishmaniasis Surveillance and Control Program and minimize the chance of new canine and human cases.

A tradução gênica é um processo que muitos estudantes do ensino médio têm dificuldade em entender e compreender, por tratar-se de um mecanismo dinâmico, complexo, de nível molecular e imperceptível aos sentidos, tornando-se abstrato e geralmente as representações em imagens estáticas dos livros didáticos e a sua abordagem são ineficientes para a compreensão. Desta forma, o objetivo deste trabalho foi avaliar o potencial didático que representações externas podem desempenhar no ensino e aprendizagem de “Síntese Proteica” por meio de uma oficina pedagógica. Participaram da oficina quarenta estudantes de uma escola pública. Os dados foram organizados e interpretados de acordo com uma análise qualitativa de conteúdo, na qual foram avaliados os conceitos predominantes, os ganhos conceituais e o tipo de interação promovida pela oficina na compreensão do tema. Os resultados indicaram que a oficina contribuiu para a melhoria (ou construção) de um modelo metal de síntese de proteínas pelos estudantes, fornecendo uma representação simbólica do processo por meio de interações guiadas. Essas interações, podem promover uma melhor aprendizagem.

In pastures subjected to stockpiling, the tiller population goes through an intense process of self-thinning, hindering the recruitment of new tillers in the subsequent season. We evaluated different pasture management strategies in late winter in an attempt to modify tiller recruitment during spring. Urochloa brizantha cv. Marandu was maintained at 4 different levels (heights) of stockpiled pasture at the end of winter: short (15.1 cm), medium (23.2 cm), tall (31.4 cm) and tall/mown (31.3 cm, mown to 8 cm). In October (early spring), the short and tall/mown pastures had a tiller appearance rate (TAR) and a population stability index (PSI) superior (P<0.05) to that of the tall pasture. During the remainder of the growing season, these characteristics (TAR and PSI) were similar for all pastures. Tiller survival rate (TSR) was also highest (P<0.05) in short pasture in early spring. TAR values were highest in early spring and these tillers persisted throughout the growing season. When stockpiling Marandu palisadegrass pasture during spring it is important to have it short at the end of winter to ensure early and intense tillering in spring. If pasture is tall at the end of winter mowing at this time before spelling is advantageous.

The study evaluated chemical composition, fermentation profile, microbial population and dry matter recovery of silages made from mixtures of palisade grass (Urochloa brizantha cv. Marandu) and forage peanut (Arachis pintoi cv. Belmonte). The experiment was conducted and analyzed in a complete randomized factorial design using 5 levels of each forage (0, 25, 50, 75 and 100% on a fresh matter basis), with and without microbial inoculant and 3 replications. The crude protein concentration increased linearly (P<0.05) and fiber concentration decreased linearly (P<0.05) as forage peanut level in silage increased. There was a positive quadratic effect (without inoculant) and positive linear effect (with inoculant) on lactic acid concentration (P<0.05) and a positive quadratic effect (P<0.05) on lactic acid bacteria population with increasing forage peanut levels in silage. The main effects of the addition of forage peanut to palisade grass at ensiling were improvement in the chemical composition and fermentation profile of the grass silage. We recommend adding 25–75% forage peanut to palisade grass prior to ensiling to improve the quality of the resulting silage but there is little merit in adding microbial inoculant to the forage at ensiling. Feeding studies with animals would verify potential benefits in production from inclusion of legume with grass at ensiling, while studies with addition of energy sources at ensiling would determine any further benefits to be achieved in silage quality.

The demand for high-quality forages is increasing in tropical regions, and could be filled with legume species of the genus Grona, which have good nutritive value. In this study, a comparison of the forage production and nutritive value of 10 accessions of Grona spp. was carried out in the field at Danzhou, Hainan from 2016 to 2018. Yield, plant height, survival rate, leaf:stem ratio and concentrations of crude protein, crude fiber, crude fat (ether extract), nitrogen free extract, crude ash, calcium and phosphorus were measured. Results showed that Grona strigillosa (syn. Desmodium strigillosum) cv. Reyan No. 27 and G. heterocarpa subsp. ovalifolia (syn. Desmodium ovalifolium) cv. Maquenque displayed the best performance, owing to their 261.3% and 235.6% higher dry matter yields, respectively, compared with the Control germplasm, G. heterocarpa subsp. ovalifolia cv. Reyan No. 16 in 2018. Cultivar Maquenque had a higher survival rate than the Control (P<0.05). Regarding nutritive value, cv. Reyan No. 27 exhibited higher crude fat and crude fiber but lower Ca concentrations than the Control (P<0.05). Based on PCA ranking, we concluded that cvv. Maquenque and Reyan No. 27 could be used as suitable candidate materials for livestock production in tropical regions of China. Further studies on their tannin concentrations and their acceptability by animals are needed before practical recommendations can be made.
