Predicting Parametric Influence of Resistance Spot Welding Process Parameters on Tensile Shear Load Using Optimization Technique
Authors: K Vignesh 
Published: July 2022

Abstract
The stainless steels such as Austenitic Stainless Steel (ASS) and Duplex Stainless Steel (DSS) are joined to optimize the Resistance Spot Welding (RSW) process parameters and predict the parametric influence on the response of Tensile Shear Load (TSL). The Response Surface Methodology (RSM) is an optimization technique which is used for optimizing the process parameters on TSL and with the help of these results a satisfactory quadratic mathematical model has been developed to predict the response. The optimal parameters and their levels are found and reported as follows: welding current = 9 kA, welding time = 0.18 seconds and electrode tip radius = 3 mm. The actual and predicted values of TSL for the optimized parameters are 17.6 kN and 17.9 kN respectively. The developed quadratic model is efficiently predicted the response with an average error percentage of 2.18. The significant and insignificant terms in the models has been identified by 95% confidence level using ‘p’ test. The insignificant terms are removed from the model and the ANOVA table is formulated only with the significant terms. Significance or effect of each term in the ANOVA table is identified by calculating the percentage of contribution and noticed that welding current has the highest significance (46%) on TSL. The macroscopic examination confirmed that the nugget is initially formed in DSS side due to its higher thermal conductivity and resistivity. The tensile shear-strain graphs are observed with the percentage of elongation varies from the minimum of 5.18 to the maximum of 8.57 which confirm the ductile failure.

Abstract
Decrease the risk of being killed and increase the food intake is an important feature of the foraging behavior of most animals. In general, foragers are vulnerable and the ability to trade-off benefits (food quantity) against costs (risk of being killed) may provide a considerable ecological advantage. Despite the increasing number of studies, the effects of food quantity and risk signals on resource selection in eusocial insect is not well understood. Here, we investigated the combination of distinct levels of food quantity and risk signals on resource selection of a Neotropical termite, Nasutitermes corniger (Termitidae: Nasutitermitinae). Manipulative bioassays with binary and multiple choices were conducted over time to check the recruitment of termite groups among resources containing different levels of food quantity and risk signals. Overall, the quantity of food resource was more important than the risk signals during the resource selection by N. corniger groups. However, termites were able to perceive the risk choosing resource with high benefits (high amount of food) and low costs (low risk signal) when it was conducted multiple bioassays with empty arenas. This work contributes to a better understanding of habitat use by termite species. Furthermore, it shows for the first time the combined effects of food quantity and risk signals on resource selection of an important ecological and economic termite species.

Abstract
Micronodular thymoma with lymphoid stroma is a rare thymic neoplasm characterized by discrete nodules of epithelial tumor cells separated by abundant lymphoid stroma. The genetic features of micronodular thymoma with lymphoid stroma remain largely unexplored. Owing to the interference of abundant intra-tumoral non-neoplastic lymphoid cells, a highly sensitive approach is necessary to study the genetic changes in these tumors. In this study, we applied a highly sensitive next-generation sequencing assay using molecular barcoding Ion AmpliSeq HD technology to study the most commonly mutated genes in thymomas, including GTF2I, HRAS, NRAS, KRAS, and TP53. A total of 12 cases of micronodular thymomas with lymphoid stroma were tested, and 2 cases also had areas of type A thymoma in their tumor bed. Two micronodular thymic carcinomas with lymphoid stroma, a histological mimic of micronodular thymoma, were also included for comparison. Recurrent GTF2I p.L424H mutations were found in all cases of micronodular thymoma with lymphoid stroma but not in micronodular thymic carcinomas. In addition, 3 cases of micronodular thymoma with lymphoid stroma also had concomitant HRAS and/or KRAS mutations. Our study shows that GTF2I p.L424H mutation is a constant genetic feature in micronodular thymoma with lymphoid stroma. This finding strongly suggests micronodular thymoma with lymphoid stroma is closely related to type A and type AB thymomas as they all share GTF2I p.L424H mutations.

Abstract
Background: Seattle Veterinary Outreach, a nonprofit organization providing free and sliding scale veterinary services to those experiencing homelessness and low-income residents of the Seattle Washington Puget Sound area, began operations in 2019. A key premise of the organization is that offering veterinary services creates a trusting relationship with pet owners that fosters guiding human clients toward obtaining services for their own health and wellbeing.1 Pet owners face significant barriers to obtaining care for themselves due to the lack of pet-friendly housing, shelter, and medical care clinics.2Methods: To support this vision, SVO partners with human care service providers to co-locate, allowing for pet-friendly access to needed services. Up until now, the decision about partners has been made based on immediate needs, circumstances, and availability. The purpose of this study was to develop a data-driven process that would assist in identifying the type of human care services needed, create a ranking system to assist in securing these services, and identify partners that can co-locate with SVO mobile clinics to address human care needs. Relying on data collected by SVO staff and volunteers and incorporating attributes of potential partners into the discussion, a data-driven process for partner outreach was created. Results: A new process was created that is currently in use and will be incorporated into staff responsibilities.Conclusion: The new process offers an opportunity to ensure that the needs of pet owners are being best served.
Stabilization of nonlinear PMSG-based wind energy conversion system via coupling memory sampled-data control with a membership function-dependent $ H_{\infty} $-approach
Authors: Yesudhas Anto Anbarasu , Joo Young Hoon 
Published: July 2022

Abstract
This study presents the coupling memory sampled-data control (CMSDC) design for the Takagi-Sugeno (T-S) fuzzy system that solves the stabilization issue of a surface-mounted permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS). A fuzzy CMSDC scheme that includes the sampled-data control (SDC) and memory sampled-data control (MSDC) is designed by employing a Bernoulli distribution order. Meanwhile, the membership function-dependent (MFD) H∞ performance index is presented, mitigating the continuous-time fuzzy system's disturbances. Then, by using Lyapunov-Krasovski functional with MFD $H_\infty$ performance index, data of sampling pattern and a constant signal transmission delay, sufficient conditions are derived. These sufficient conditions are linear matrix inequalities (LMIs), ensuring the global asymptotic stability of PMSG-based WECS under the designed control technique. Besides, the proposed method is demonstrated by a numerical simulation implemented on the PMSG-based WECS. Finally, Rossler's system demonstrates the effectiveness and superiority of the proposed method.

Published: July 2022

Abstract
Background: In the past decade, Brazil has significantly reduced the prevalence of schistosomiasis through a combined effort of early treatment of infected people, expansion of basic sanitation infrastructure and educational measures. Despite these efforts, in some areas, prevalence of schistosomiasis exceeds 20% of the school population, who lack knowledge of the risks of the disease. Action can be taken in schools to empower this population about their health condition. This paper describes the role of the teacher as a multiplier of knowledge about schistosomiasis and proposes two different approaches to training these teachers.Methods: This study used mixed methods to evaluate training of teachers and educational intervention with those teachers’ pupils. Two training courses, each of 40 hours of face-to-face activity, were offered to 19 teachers. The courses included classroom activities and laboratory and field work. After the training, the teachers conducted activities on schistosomiasis with their pupils. These activities involved constructing educational materials and cultural productions. The pupils’ knowledge about the disease was evaluated before the activities and 12 months later. The teachers’ acceptance and perceptions were assessed through structured interviews and subsequent thematic analysis. Infection status for Schistosoma mansoni was also assessed using the Kato Katz stool test.Results: The parasitological study showed 31.6% of the teachers and 21.4% of the pupils to be positive for S. mansoni. The teachers’ knowledge of important aspects of schistosomiasis transmission and prevention was fragmented and incorrect. The teachers’ knowledge changed significantly after the training and they were strongly accepting of the pedagogical methods used during the training. The level of their pupils’ knowledge about the disease had increased significantly. However, most pupils responded that, even after the educational activities, they still had contact with the city’s contaminated waters.Conclusions: The results of this study underline the importance of schools and teachers as partners in controlling and eliminating schistosomiasis. Teacher training on the disease significantly increases their pupils’ knowledge, reflecting empowerment with regard to local health conditions.

Published: July 2022

Abstract
The inherent nonlinear magnetization dynamics in spintronic devices makes them suitable candidates for neuromorphic hardware. Among spintronic devices, spin torque oscillators such as spin-toque oscillators and spin Hall oscillators have shown the capability to perform recognition tasks. In this paper, we demonstrate that the magnetization dynamics of a single spin Hall oscillator can be nonlinearly transformed by harnessing input pulse streams and can be utilized for classification tasks. The spin Hall oscillator utilizes the microwave spectral characteristics of its magnetization dynamics for processing a binary data input. The spectral change due to the nonlinear magnetization dynamics assists in real time feature extraction and classification of 4-bit binary digits. The performance is tested for the classification of the standard MNIST handwritten digit data set and achieved an accuracy of 83.1%. Our results suggest that modulating time driven input data can generate diverse magnetization dynamics in the spin Hall oscillator, which is suitable for temporal or sequential information processing.

Published: July 2022

Abstract
Local food has gained popularity and has become one of the important core elements in the food and tourism industry to market many tourism destinations around the world. Many studies have found that selling and serving local food, enables tourists to get connected to the local culture as well as the culinary taste and practice of people who live in a particular place or country. In the efforts of destination marketing by promoting local food as part of tourism experiences, proper planning and understanding on specific dishes or meals are vital and are often emphasized by relevant food and tourism related authorities. Moreover, the choice and selection of specific local dishes or meals provide tourists with a better understanding on the type of food and experience that they will encounter when traveling to a particular place or country. However, this exercise will at the same time, prevent the potential of some local foods to be discovered due to the idea of promoting only local foods that have commercial and marketable values in the eyes of tourists rather than to educate tourists on all of the authentic food traditions which is part of the identity of the local people. Unfamiliarity with certain local dishes and/or meals prior to traveling to a tourism destination may be unappealing to some tourists. Thus, the food and tourism marketers as well as relevant stakeholders should make careful considerations of their choice of dishes and meals to speak and represent the local food as part of the identity of a place or country. This study, delves into the concept of the unfamiliarity or bizarre local food as a highlight of food and tourism destinations, specifically discussing on the possibilities of bizarre local foods (i.e. dishes and/or meals) of Terengganu that have been ignored or gotten less attention in promoting food tourism experiences for Terengganu, Malaysia.

Abstract
Background: Pseudobulbar affect (PBA), referring to exaggerated or inappropriate episodes of laughing and/or crying without an apparent motivating stimulus, has been mainly attributed to bilateral degeneration of corticobulbar tracts. We aimed at exploring brain functional connectivity (FC) correlates of PBA in patients with amyotrophic lateral sclerosis (ALS), the most common motor neuron disease, frequently associated with PBA.Methods: Resting state functional MRI (RS-fMRI) independent component (ICA) and seed-based analyses and voxel-based morphometry (VBM) whole-brain analysis were performed on 27 ALS patients (13 with PBA; 14 without PBA) and 26 healthy controls (HC), for investigating functional and structural abnormalities in ALS patients compared to HC and in patients with PBA compared to patients without PBA.Results: Between-patient analysis revealed different FC patterns, especially regarding decreased FC in several areas of cognitive (default mode, frontoparietal, salience) and sensory-motor networks in patients with PBA compared to those without PBA. However, no significant differences were found in gray matter atrophy. Seed-based analysis showed increased FC between middle cerebellar peduncles and posterior cingulate cortex and decreased FC between middle cerebellar peduncles and left middle frontal gyrus in patients with PBA compared to patients without PBA. Conclusions: Our findings suggest that some alterations of fronto-tempo-parietal-cerebellar circuits could be related to PBA in ALS. In particular, the abnormal FC between cerebellum and posterior cingulate cortex and left middle frontal gyrus in patients with PBA compared to patients without PBA highlights a crucial role of the cerebellum in regulating emotion expression in patients with ALS.
Observing flow of He II with unsupervised machine learning

Published: July 2022

Abstract
Time dependent observations of point-to-point correlations of the velocity vector field (structure functions) are necessary to model and understand fluid flow around complex objects. Using thermal gradients, we observed fluid flow by recording fluorescence of \({He}_{2}^{*}\) excimers produced by neutron capture throughout a ~ cm3 volume. Because the photon emitted by an excited excimer is unlikely to be recorded by the camera, the techniques of particle tracking (PTV) and particle imaging (PIV) velocimetry cannot be applied to extract information from the fluorescence of individual excimers. Therefore, we applied an unsupervised machine learning algorithm to identify light from ensembles of excimers (clusters) and then tracked the centroids of the clusters using a particle displacement determination algorithm developed for PTV.

Accessing the relative performance of fast molecular dating methods for phylogenomic data
Authors: Costa Fernanda P. , Schrago Carlos G. , Mello Beatriz 
Published: July 2022

Abstract
Due to advances in genome sequencing techniques, there was a significant growth of phylogenomic datasets. This massive amount of data represents a computational challenge for molecular dating with the Bayesian approach that relax the assumption of rate constancy. To overcome these issues, over the last few decades, rapid molecular dating methods have been proposed. However, comparative evaluation of their relative performances on empirical data sets is lacking. We analyzed 23 empirical phylogenomic datasets to investigate the performance of two commonly employed fast dating methodologies, the penalized likelihood (PL), implemented in treePL, and the relative rate framework (RRF), implemented in RelTime. They were compared to Bayesian analysis under the same models and calibration settings. We found that the RRF was computationally faster and generally provided node age estimates statistically equivalent to Bayesian divergence times. Furthermore, contrasted to Bayesian dating, PL time estimates were excessively precise. To approximate Bayesian approaches, RelTime is an efficient method with significantly lower computational demand, being up to more than 100 times faster than treePL. Thus, to alleviate the computational burden of Bayesian divergence time inference in the era of massive genomic data, molecular dating can be facilitated using the RRF, so that evolutionary hypotheses can be tested more quickly and efficiently.

Abstract
This study aimed to evaluate the performance of the Novel electro-oxidation unit for the disinfection of wastewater from technoeconomic point of view. The cell was fabricated based on patent design with a total volume of 3L containing nine electrodes (6graphite and 3stainless steel) with cylindrical shape and connected to DC power supply. Determination of optimum operating parameters were investigated in batch mode on synthetic wastewater through studying effect of contact time, current density(CD), total dissolved solids concentration(TDS) and bacterial density. Also, continuous mode experiment was studied on real wastewater from agricultural drain and secondary wastewater treatment plant. The results of batch mode revealed that the optimum operational conditions that achieved the complete removal E.coli was at contact time of 5 minutes, TDS = 2000 mg/L and CD = 4mA/Cm2. Application of these conditions on the continuous mode experiment indicated the complete removal of all bacterial indicators after 5 minutes in the drainage wastewater and after 2 minutes in the secondary treated wastewater. The physico-chemical characterization indicated also, no formation of chlorine by products in the process. The electrical consumption was calculated in the continuous mode and found to be 0.5 kWh/m3 with operational cost about 0.06 $/m3 including cost of adding chemicals to increase the TDS. This proved that this novel electro-oxidation unite is cost effective for disinfection of wastewater and complete removal bacterial pollutants than other conventional treatment methods.

Abstract
We report a 47-year-old male patient who presented with irregular fever, chills, fatigue, body aches, and an occasional cough while traveling between Fujian and Hebei, China in 2020. Due to delayed molecular diagnosis, he was laboratory confirmed in 2021 by reverse transcription PCR and gene sequencing which confirmed that he was infected with thrombocytopenia syndrome virus (SFTSV). Extension of molecular diagnosis on SFTSV is one of the best strategies in response to the virus epidemic.
