Abstract
Optimizing Resistance spot welding (RSW), often used as a time and cost-effective process in many industrial sectors, is very time-consuming due to the obscurity inherent within process with numerous interconnected welding parameters. Small changes in values will give effect to the quality of welds which actually can be easily analysed using application tool. Unfortunately, existing software to optimize the parameters are expensive, licensed and inflexible which makes small industries and research centres refused to acquire. In this study, application tool using open-sourced and customized algorithm based on artificial neural networks (ANN) was developed to enable better, fast, cheap and practical predictions of major parameters such as welding time, current and electrode force on tensile shear load bearing capacity (TSLBC) and weld quality classifications (WQC). A supervised learning algorithm implemented in standard backpropagation neural network gradient descent (GD), stochastic gradient descent (SGD) and Levenberg-Marquardt (LM) was constructed using TensorFlow with Spyder IDE in python language. All the display and calculation processes are developed and compiled in the form of graphical user interface (GUI) using Qt designer and PyQt5. The standalone capability was created with customized icon by using Pyinstaller to enable a self-execution in windows platform. Results showed that this low-cost application tool Q-Check based on ANN models can predict with 80% training and 20% test set on TSLBC with an accuracy of 87.220%, 92.865% and 93.670% for GD, SGD and LM algorithms respectively while on WQC 62.5% for GD and 75% for both SGD and LM. It is also expected that tool with flexible GUI can be widely used and enhanced by practitioner with minimum knowledge in the domain.

Abstract
Objective: To compare the effectiveness of the slider, tensioner neurodynamic mobilization techniques and stretching exercises on pain, ROM, and functional disability in patients with chronic discogenic sciatica.Design: A pre-test post-test three-armed comparative study designSetting: Outpatient clinics, faculty of physical therapy, Kafrelsheikh UniversityParticipants: 36 patients with unilateral chronic discogenic sciatica were randomly allocated into three equal groups: Group (A) slider neurodynamic mobilization Group (B) tensioner neurodynamic mobilizationGroup (C) stretching exercises of back extensors, hamstrings, and gastrocnemius musclesTreatment was given three sessions per week for two weeks.Outcome measures: all patients were examined by Visual Analogue scale (VAS) for pain intensity, Modified-Modified Schober test (MMST) for lumbar flexion ROM, Goniometer for hip flexion and knee extension ROM, and Oswestry Disability Index (ODI) for functional assessment. Results: there were no statistically significant differences between groups at baseline (p<0.05). There were statistically significant differences in the slider and tensioner groups compared to the stretching group for all variables. Furthermore, statistically significant differences were found in the slider technique as compared to the tensioner technique regarding ROM of lumbar flexion (p = 0.03), hip flexion (p = 0.004), and knee extension (p = 0.005). Conclusion: Slider and tensioner neurodynamic mobilization techniques are more effective than stretching exercises in terms of reducing pain, increasing ROM, and improving function. Slider technique is more effective in ROM improvement.

Abstract
Purpose: Our aim was to explore potential risk factors for Preterm birth (PTB) that had been associated with the patient's obstetric history and which had not been previously examined in depth.Methods: Retrospective analysis of all women who had their first, term, singleton delivery and their second delivery, between 2013 and 2020. Obstetrical and neonatal outcomes, including the rate of preterm birth in the following delivery, were compared among three different groups, based on complications occurring the first pregnancy: emergency end second stage cesarean, large for gestational age neonate and delivery which required a uterine and/or cervical revision. Results: There were 233 women of whom 77 underwent emergency end second stage cesarean delivery and 156 who underwent elective CD in their first delivery at term, with no difference in the rate of PTB between the two groups in the subsequent delivery (3.9% vs. 3.21%, p<0.72). There were 396 women with infants weighing more than 3.8kg and 5,136 women with infants weighing less than 3.8kg, in their first term delivery. These two groups did not differ in the rate of PTB in their subsequent delivery (1.52% vs. 2.94%, p<0.1). Finally, there were 298 women who underwent uterine and/or cervical revision who were compared to 5,234 women without these procedures, in their first term delivery. Again, there was no difference between these groups in the rate of PTB in the subsequent delivery (2.35% vs. 2.87%, p<0.72). Conclusion: Risk factors examined in our analysis did not emerge as risk factors for PTB.

Abstract
Background
Identification of frailty is crucial to guide patient care for the elderly. The Clinical Frailty Scale (CFS) is a reliable, synthesis and clinical judgment-based tool. However, a validated Chinese version of CFS (CFS-C) is lacking. The aim of this study is to describe the translation process of CFS into traditional Chinese and to evaluate its reliability and validity in a geriatric study population in Taiwan.
Methods
This cross-sectional study recruited 221 geriatric outpatients aged 65 years or older at a medical center in Taipei, Taiwan. The Chinese version of CFS was produced following Brislin’s translation model. Weighted kappa for agreement and Kendall’s tau for correlation were used to assess inter-rater reliability (a subgroup of 52 outpatients) between geriatricians and one research assistant, and validity tests (221 outpatients) by comparing CFS-C with Fried frailty phenotype and Frailty Index based on Comprehensive Geriatric Assessment (FI-CGA). Correlation between CFS-C and other geriatric conditions were also assessed.
Results
The inter-rater reliability revealed moderate agreement (weighted kappa = 0.60) and strong correlation (Kendall’s tau = 0.67). For criterion validity, CFS-C categorisation showed fair agreement (weighted kappa = 0.37) and significant correlation (Kendall’s tau = 0.46) with Fried frailty phenotype, and higher agreement (weighted kappa = 0.51) and correlation (Kendall’s tau = 0.63) with FI-CGA categorisation. CFS-C was significantly correlated with various geriatric assessments, including functional disability, physical performance, hand grip, comorbidity, cognition, depression, and nutrition status. No significant correlation was found between CFS-C and appendicular muscle mass.
Conclusions
The CFS-C demonstrated acceptable validity and reliability in Chinese older adults in Taiwan. Development of CFS-C enhanced consistency and accuracy of frailty assessment, both in research and clinical practice.

Published: March 2022

Abstract
Facial expressions in non-human animals are closely linked to their internal affective states , with the majority of empirical work focusing on facial shape changes associated with pain. However, existing tools for facial expression analysis are prone to human subjectivity and bias, and in many cases also require special expertise and training. This paper presents the first comparative study of two different paths towards automatizing pain recognition in facial images of domestic short haired cats (n = 29), captured during ovariohysterectomy at different time points corresponding to varying intensities of pain. One approach is based on convolutional neural networks (ResNet50), while the other – on machine learning models based on geometric landmarks analysis inspired by species specific Facial Action Coding Systems (i.e. catFACS). Both types of approaches reach comparable accuracy of above 72%, indicating their potential usefulness as a basis for automating cat pain detection from images.

Authors: Kumari Ranjana , Tomar V. K. , Sharma Ankit 
Published: March 2022

Abstract
A compact semi-hexagonal-shaped MIMO antenna loaded with a planar SRR (split-ring resonator) structure is presented for Terahertz applications. The single radiating element consists of a semi-hexagonal shape metallic patch loaded with SRR-CC (Split ring ResonatorConnected C shape) metamaterial unit cell to enhance the impedance bandwidth as well as gain of the proposed antenna. The proposed antenna element can be easily extended into two-port and four-port MIMO antenna configurations. Four radiating elements of the proposed antenna are printed on 122.4*122.4 um 2 quartz substrate having a thickness of 10 um. The radiating elements are placed orthogonally to achieve high isolation and miniaturization in the MIMO system. The proposed antenna exhibits super-wide impedance bandwidth (S 11 ≤ -10dB) in the range of 0.9–10.1 THz (with fractional bandwidth of 168% at f 0 =5.5 THz) while isolation of antenna is more than 20 dB in the whole operating band. The peak gain of the antenna is 7.51dBi with more than 95% radiation efficiency in the entire band. The stable radiation pattern, high gain, high radiation efficiency, and good diversity performance of the proposed antenna make it suitable for many THz applications such as breast cancer detection, sugar measurement, drug detection.

Published: March 2022

Abstract
Absorptive capacity has emerged as one of the most important concepts in the field of strategic management. It has been seen as an essential factor in forming innovation capability. However, the result may differ without the presence of knowledge management. This study discusses knowledge management’s role as a mediating variable to the relationships between types of absorptive capacity and innovation capability. We focused the research on young professionals, hence we gathered data from 180 alumni of Business Administration major who already have sufficient working experience to observe their knowledge management, absorptive capacity, and innovation capability. We used path analysis methodology with SmartPLS software as an assisting tool. Our result shows that realized absorptive capacity has a significant effect on innovation capability with the mediating role of knowledge management.

Abstract
Since the first alert launched by the World Health Organization (5 January, 2020), COVID-19 has been spreading out to almost 200 countries and territories. As of January 23, 2022, in total, over 346 million confirmed cases and over 5.5 million deaths have been reported worldwide. This causes massive losses in the economy and jobs globally and confining about 58% of the global population. In this paper, we introduce SenWave, a novel sentimental analysis work using 106+ million collected tweets and Weibo messages to evaluate the global rise and falls of sentiments during the COVID-19 pandemic. To make a fine-grained analysis on the feeling when we face this global health crisis, we annotate 10K tweets in English and 10K tweets in Arabic in 10 categories, including optimistic, thankful, empathetic, pessimistic, anxious, sad, annoyed, denial, official report, and joking. We then utilize an integrated transformer framework, called simpletransformer, to conduct multi-label sentimental classification by fine-tuning the pre-trained language model on the labeled data. Meanwhile, in order for a more complete analysis, we also translate the annotated English tweets into different languages (Spanish, Italian, and French) to generated training data for building sentiment analysis models for these languages. We provide detailed analysis and interesting discoveries on how the emotions evolve overtime. SenWave thus reveals the sentiment of global conversation in six different languages on COVID-19 (covering English, Spanish, French, Italian, Arabic and Chinese), followed the spread of the epidemic. The conversation showed a remarkably similar pattern of rapid rise and slow decline over time across all nations, as well as on special topics like the herd immunity strategies, to which the global conversation reacts strongly negatively. Overall, SenWave shows that optimistic and positive sentiments increased over time, foretelling a desire to seek, together, a reset for an improved COVID-19 world. We share the dataset with public to help other social impact studies of Covid-19, and fine-grained sentimental analysis tasks.

Abstract
Background: Vitamin D insufficiency or deficiency is associated with an altered microbiota in older men. However, the relationship between the gut microbiota and 25-hydroxyvitamin D (25(OH)D) levels remains unknown in postmenopausal women. In this study, fecal microbiota profiles for 88 postmenopausal women in the high 25(OH)D (HVD) group (n=44) and the low 25(OH)D (LVD) group (n=44) were determined. An integrated 16S rRNA gene sequencing and liquid chromatography–mass spectrometry (LC–MS)-based metabolomics approach was applied to explore the association of serum 25(OH)D levels with the gut microbiota and fecal metabolic phenotype. Adjustments were made using several statistical models for potential confounding variables identified from the literature. Results: The results demonstrated that the community diversity estimated by the Observe, Chao1 and ACE indexes was significantly lower in the LVD group than in the HVD group. Additionally, two kinds of characteristic differences in the microflora were analyzed in the HVD group, and ten kinds of characteristic differences in the microflora were analyzed in the LVD group. We observed that some bacteria belonging to the genera Bifidobacterium, Bacillus, F0332 and Gemella, were enriched in the LVD group, as were other genera, including Lachnoclostridium, UC5_1_2E3, Ruminococcus_gnavus_group and un_f_Lachnospiraceae. Christensenellaceae, Eggerthellaceae and Cloacibacillus were enriched in the HVD group. The L-pyroglutamic acid, inosine, and L-homocysteic acid levels were higher in the HVD group and were negatively correlated with the 1,2-benzenedicarboxylic acid and cholic acid metabolic levels. Conclusions: These observations provide a better understanding of the relationships between serum 25(OH)D levels and the fecal microbiota and metabolites in postmenopausal women.

Published: March 2022

Abstract
Corn straw incorporation in soil has been regarded as an environment-friendly approach for straw utilization. However, the straw incorporation has been a challenge under a cold and dry climate due to a slow decomposition. This field study was to use a novel approach to incorporate corn straw into soil during fall season with plastic film cover, in an effort to enhance the straw degradation. Two-year field experiments were conducted in Northeast China to investigate the effects of four treatments: including 1) straw incorporation with film cover; 2) straw incorporation only; 3) film cover only; and 4) control, on soil properties and corn growth. Soils and corn plants were collected during the growing season and analyzed for soil temperature and moisture, straw degradation, corn biomass, grain yield, and water use efficiency. Results indicated that straw incorporation with film cover increased grain yield by 53% as compared to straw incorporation only and by 102% to control, but did not significantly differ from film cover only. The straw decomposition under film cover was 20% faster, significantly higher than that of the straw incorporation only treatment. In all cases, soil water content before planting, corn water uptake, and corn water use efficiency under straw incorporation with film cover were significantly higher than straw incorporation only and control, but did not significantly differ from film cover only. Surface film cover resulted in 10-day earlier corn tasseling in compared to treatments without film cover. This field study demonstrated that straw incorporation with film cover would enhance straw degradation in soil, improve soil properties, and increase corn yield and water use efficiency, which could be potentially used as the sustainable soil management practice in Northeast China.
Mais Médicos Program and Human Capital in Argentina: Brain Drain in the Health Sector?
Authors: González Fernando Antonio Ignacio , Cantero Lara Sofía , Szyszko Pablo Ariel , Bys Joel Heman 
Published: March 2022

Abstract
The Mais Médicos program (2013) tried to attract physicians to rural and peripheral areas of Brazil based on the international immigration of these professionals. Its creation generated widespread concern in the border areas of Argentina due to the potential brain drain (emigration of qualified professionals) in the health sector. In this paper we provide evidence on this topic. The identification strategy exploits the plausibly exogenous timing in the implementation of the program and the different levels of proximity of the Argentine provinces with respect to Brazil. The results suggest that, despite the widespread belief of a brain drain towards Brazil, the availability of physicians did not show a significant reduction, after the program, in the border areas. This is robust against multiple checks and placebos. From a territorial equity perspective, there is no evidence that the creation of the program has contributed to widening regional disparities in Argentina (i.e. fewer physicians in the poorest region).

Abstract
Purpose
To investigate the correlation between homocysteine, coagulation function indexes and breast cancer risk and clinicopathological characteristics.
Methods
From January 2018 to December 2018, coagulation function test results and clinicopathological data from 369 female breast cancer patients were collected. 183 women with benign breast disease were selected as the control group. Results: The levels of HCY, Fbg and D-D in the peripheral blood of breast cancer patients were higher than those of the control group (P < 0.05); PT, AT-Ⅲ, PC, F-VIII, and α2-AP were lower (P < 0.05). Concentrating on different menstruation status, serum levels of AT-Ⅲ, PC and α2-AP in menopausal patients were lower than those in the control group (P < 0.05); HCY, Fbg and D-D in postmenopausal patients were higher than those in the control group (P < 0.05), while the PT, F-VIII and α2-AP were lower than those of the control group (P < 0.05). The levels of HCY, Fbg, AT-Ⅲ, PC, α2-AP, FDP, and D-D are higher in T2-T4 breast cancer patients than in Tis-T1 breast cancer patients, PT and ATPP levels are higher in Tis-T1 breast cancer patients; Fbg, AT-Ⅲ, α2-AP levels are increased in breast cancer patients with lymph node metastasis. Among premenopausal breast cancer patients, HCY, Fbg, and D-D levels were increased in patients with T2-T4 stage (P < 0.05); Fbg, AT-Ⅲ, and α2-AP levels were increased in patients with lymph node metastasis (P < 0.05). In postmenopausal patients, the levels of PT (SEC), AT-Ⅲ, PC, α2-AP, FDP, and D-D in the T2-T4 stage are higher than those in the Tis-T1 stage, and the levels of AT-Ⅲ and α2-AP in the lymph node metastasis increased in the number of patients (P < 0.05). The abnormal rate of HCY and PT in the triple-negative patients was higher than that in the Luminal A + B group and the HER-2 overexpression group. The abnormal rate of Fbg in the HER-2 overexpression patients was higher than that in the Luminal A + B group and the triple-negative group (P < 0.05).
Conclusions
Homocysteine and abnormal blood coagulation are related to the risk of breast cancer, and tumor size, lymph node metastasis and molecular typing in breast cancer patients.
