Contrast‐Induced Acute Kidney Injury in Patients on SGLT2 inhibitors Undergoing Percutaneous Coronary Interventions: A Propensity-Matched Analysis
Authors: Hua Rui , Ding Ning , Guo Hanqing , Wu Yue , Yuan Zuyi , Li Ting
Published: March 2022

Background
Contrast-induced acute kidney injury (CI-AKI) is a common complication of patients undergoing percutaneous coronary intervention (PCI). Sodium-glucose cotransporter-2 (SGLT2) inhibitors are new medications that improve cardiovascular and renal outcomes in patients. Data regarding the influence of SGLT2 inhibitor on the CI-AKI incidence and renal outcomes of patients undergoing PCI are limited. The aim of this study was to examine the real-world risk of CI-AKI in SGLT2 inhibitor users undergoing PCI.
Methods
We used longitudinal data from the medical records of First Affiliated Hospital of Xi’an Jiaotong University. We selected SGLT inhibitor users and nonusers (patients with T2D without SGLT2 inhibitor prescription) undergoing PCI. We determined CI-AKI by the ESUR (European Society of Urogenital Radiology, ESUR) and KDIGO (Kidney Disease: Improving Global Outcomes) definition (AKIKDIGO). We performed 1:1 nearest-neighbor propensity matching and calculated unadjusted odds ratios (ORs) and adjusted ORs (aORs; accounting for covariates poorly balanced) for AKI in primary and sensitivity analyses. We compared the renal function indicators in users and nonusers at 24h, 48h and 72h post-PCI.
Results
We identified 242 SGLT2 inhibitor users and 242 nonusers in the cohort. The unadjusted odds ratios of CI-AKIESUR were 63% lower in users (OR 0.37 [95% CI 0.18–0.68]; P = 0.01), which was unchanged (aOR 0.37 [95% CI 0.19–0.67]; P < 0.01) post adjustment. These estimates did not qualitatively change across several sensitivity analyses. There was no significant difference in urea nitrogen, creatinine, and eGFR values ​​between the two groups before PCI, as well as at 24h, while the creatinine (48h and 72h post-PCI) and CyC (24h and 48h post-PCI) were significantly lower than those in the nonuser group (P < 0.05).
Conclusions
Our findings do not suggest an increased risk of CI-AKI associated with SGLT2 inhibitor use in CAD patients with T2D undergoing PCI.

Oxidative stress and disturbances of mitochondria function in the brain have been recognized to play a crucial role in the pathophysiological mechanism of Alzheimer’s Disease (AD). However, little is known about these changes at an early age of AD, which could be crucial for therapeutic strategy for the disease. In this study, we used biochemical, and quantitative polymerase chain reaction for determination of expression of genes encoding enzymes related to the antioxidative defence including Sirtuins (Sirts) and DNA-bound poly (ADP-ribose) polymerases (PARPs). Moreover, expression of genes related to mitochondrial dynamic, biogenesis and function in the brain cortex of 3- and 6-month-old FVB mice with London mutation (V7171) was analysed and compared with mice without transgene. Results indicated significant decreases in mRNA expression encoding SOD2, Sirt1 and PARP1 in the 3-month-old AD Tg mice and an increase in expression of PARP-1 in the 6-month-old AD Tg. Although levels of mRNA encoding subunits of mitochondrial respiratory complexes (I-III) were negligible altered, there was upregulation of gene encoding subunit of complex IV and proteins related to mitochondria biogenesis and dynamic, such as the Neuronal Respiratory Factors (NRF1) and NRF2, Opa1, Fis1, and Drp1 in the AD mice. Our data indicate downregulation of genes related to antioxidation and activation of genes encoding mitochondrial biogenesis and fission / fusion at early age of the AD mice. The ability to identify changes in gene expression for Sirt1, SOD2, Fis1 and Drp1 at an early age suggest potential therapeutic targets for retarding the pathological progression in AD.

Published: March 2022

The rapid adoption of online technologies to deliver postsecondary education amid the COVID-19 pandemic has highlighted the potential for online learning, as well as important equity gaps to be addressed. For over ten years, McMaster University has delivered graduate global health education through a blended-learning approach. In partnership with universities in the Netherlands, India, Thailand, Norway, Colombia, and Sudan, experts from across the Consortium deliver lectures online to students around the world. As the Consortium has expanded, we have reflected on how artificial intelligence can be harnessed to integrate multilingual group work into course offerings, challenging the dominant use of English as the principal language of instruction in global health education. In 2020, two courses were piloted with small groups of students from Canada and Colombia using machine translation supported by bilingual tutors. Students met weekly via video conferencing software, speaking in English and Spanish and relying on machine translation software to transcribe and translate for group members. Our experience as tutors and instructors in these multilingual groups highlights the potential for machine translation to bridge language divides, while also underscoring the limitations of currently available technology. Further research is needed to investigate the potential for machine translation in facilitating multilingual online education as a pathway to more equitable and inclusive online learning environments.
Spatial and temporal scale-dependence of the strength of migratory connectivity in a North American passerine
Authors: Sharp Andrew , Rushing Clark , Contina Andrea , Ruiz-Gutierrez Viviana , Sillett Scott , Bridge Eli , Besozzi Elizabeth , Muller John , Kelly Jeff , Given Aaron
Published: March 2022

Background
Migratory connectivity describes the extent to which portions of a migratory population that are spatially associated during one stage of the annual cycle remain associated during other stages of the annual cycle. The strength of migratory connectivity may vary spatially across a species’ range and temporally as individuals move through stages of their annual cycle. Few studies have quantified this spatial and temporal variation in the strength of migratory connectivity within a single species.
Methods
We investigated spatial and temporal variation in the strength of migratory connectivity in Painted Buntings (Passerina ciris), a small migratory bird that, uniquely among North American songbirds, breeds in disjunct eastern and western populations. Using tracking data from 113 individuals sampled at eleven breeding sites across the species’ breeding distribution, we quantified the strength of connectivity at multiple spatial and temporal scales.
Results
We found strong breeding-to-winter connectivity at the range-wide scale, with interior and eastern Painted Buntings remaining separate throughout the annual cycle, but weak connectivity within populations, with individuals from different regions of both populations mixing extensively on the wintering ground. Despite weak breeding-to-winter connectivity within populations, the interior population displayed strong breeding-to-molting connectivity, with birds from different breeding sites showing distinct migratory strategies during the molting period.
Conclusion
These results demonstrate the extent to which the strength of migratory connectivity can vary across both space and time within a single species and underscore the importance of careful sampling design when quantifying this metric. Because inferences about the strength of connectivity can be sensitive to when and where sampling occurs, there is an urgent need for continued focus on study design regarding migratory connectivity.
Risk Level Assessment of Typhoon Hazard based on Aversion Utility
Authors: Liu Guilin , Nong Xiuxiu , Kou Yi , Wu Fang , Yu Pubing
Published: March 2022

In the context of climate change where natural disasters are frequent, assessing disaster risk can provide great help for relevant risk decisions. Based on the loss expectation theory, this paper proposes a method for quantitatively assessing typhoon disaster risk. In particular, the probability of typhoon occurrence is calculated by fitting the best structure function of the samples to the joint distribution of wave height, water increase, and wind speed. The loss expectation is then expressed as the product of the typhoon occurrence probability and the aversion utility loss, which is used to quantify the loss result of a typhoon disaster. In addition, a risk level map is created using the theory of aversion utility, with the direct economic loss rate and the proportion of disaster-affected population as indicators. The calculation results show that the absolute loss value considering the aversion utility is slightly higher than the product of the probability and the loss value, indicating that the new model reflects the social group's aversion to typhoon disaster risk. The diagram of risk level zoning showed that, excluding typhoon No.1306 Rumbia, the risk level assessments of the remaining typhoons, in accordance with affected population and direct economic loss, were basically consistent. This evaluation model, the outcomes of which can serve as a foundation and reference for certain risk assessment and decision-making, has some feasibility and practicability.

Published: March 2022

(Background) Incidence of adenocarcinoma of the esophagogastric junction (AEG) is increasing in Japan as well as Western Country. However, there is no consensus on treatment strategy. The purpose of this study was to determine the optimal range of resection and lymph node dissection for Siewert type II AEG and to develop a strategy for treatment that includes adjuvant therapy to improve the survival rate. (Methods)We retrospectively investigate 88 cases of advanced AEG in patients who underwent surgery with lymph node dissection with 52 cases of superficial AEG, 23 of whom underwent endoscopic treatment (endoscopic mucosal resection [EMR] or endoscopic submucosal dissection [ESD]), and 29 of whom underwent surgery with lymph node dissection. (Results) The optimal lymph nodes to resect for advanced AEG were No. 110, 1, 2, 3, 7,11. According to area of actual lymph node metastasis, lymphadenectomy of lymph nodes 1, 2, 3, 7, and 11 was sufficient to improve survival of patients with superficial AEG. The 5-year overall survival rates were 88% for patients treated with ESD, 78% for those with superficial AEG who under-went surgery, and 24% for those with advanced AEG (p = 0.011). There were no differences in survival between patients who received postoperative adjuvant therapy with S-1 for advanced AEG and those who received surgery alone (p = 0.5192).(Conclusion) Although surgical procedures of superficial and locally advanced AEG are standardized, the role of adjuvant therapy for AEG is still controversial. We recommend nab-paclitaxel plus radiotherapy for advanced AEG as neoadjuvant therapy.

Published: March 2022

Purpose
To observe and statistic the probability of presence and the anatomy of the vessel arising via the inferior margin of the pancreas and traveling within the transverse mesocolon, and analyze its clinical significance.
Methods
Patients who underwent surgery for transverse colon cancer or descending colon cancer from January 2020 to November 2021 and a non-specific cadaver were included in this study. We observed and recorded intraoperatively for the probability of presence and the anatomy of the vessel arising via the inferior margin of the pancreas and traveling within the transverse mesocolon. And its property was determined by tissue slice.
Results
A total of 84 patients were included, of whom 72 (85.7%) patients could observe intraoperatively the vessel which was confirmed by tissue slice. The vessel was also observed in a nonspecific cadaver. Originating from transverse pancreatic artery, often one, sometimes two, rarely three vessels arising via the inferior margin of pancreas, supplied the left transverse colon. Artery and vein parallel ran, and it was difficult to separate them due to their small diameter, but the vessel may thicken under certain conditions, increasing blood supply.
Conclusion
The vessel, which is not yet reported and named in the literature, can be called the subpancreatic transverse colon vessel, which has a high probability of presence in humans and may be of great significance to human physiological anatomy, surgery, and oncology, and deserves recognition and attention from surgeons.
Raindrop size distribution and rainfall attenuation modeling in central Africa
Authors: NTANGUEN Patrick Herve
Published: March 2022

Raindrop sizes were measured in Douala, Cameroon ( 4o03'N, 9o42'E) using a Parsivel disdrometer. The data obtained are used for the analysis of the drop size distribution (DSD) and specific rain attenuation modeling in the 5-150 GHz frequency range. The Lognormal and gamma distribution models are employed using the method of moments estimation, considering the third, fourth, and sixth-order moments. The parameter fits for the two DSD models proposed here for different values of rain rates are investigated. The specific rainfall attenuation using the Douala DSD models is compared to the ITU-R models in vertical and horizontal polarisation and models for some countries with different climates such as semi-arid, tropical, and subtropical in Africa. The comparison with the ITU-R model shows significant differences occurring at high frequency with both high and low rainfall rates. The comparison with other regions of Africa also shows that Douala is characterized by equatorial climate, and Durban characterized by subtropical climate show similar rainfall attenuation characteristics at operating frequency range 10≤ f ≤150 GHz, especially at a lower rain rate. At a higher rain rate, specific rain attenuation at Douala is always higher than in other African locations. The proposed models are very important for the determination of rainfall attenuation for terrestrial and satellite systems.
Nivolumab Plus Ipilimumab with Chemotherapy for Advanced Non-Small-Cell Lung Cancer：A Cost-effectiveness Analysis.
Authors: Zhu Youwen , Liu Kun , Peng Libo
Published: March 2022

Introduction: The CheckMate 9LA trial indicated that nivolumab plus ipilimumab with two cycles of chemotherapy improve overall survival for advanced non-small-cell lung cancer (NSCLC). However, the high cost of immunotherapy, we assessed the cost-effectiveness of nivolumab plus ipil::umab with two cycles of chemotherapy in the first-line setting for treatment of patients with advanced NSCLC from the United States (US) payers’ perspective. Methods: A comprehensive Markov model was developed to evaluate cost and effectiveness of nivolumab plus ipilimumab with two cycles of chemotherapy in first-line therapy for advanced NSCLC. We estimated life years (LYs), quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs). Then, one-way and probabilistic sensitivity analyses were performed. Additional subgroup analyses were considered. Results: Nivolumab plus ipilimumab with two cycles of chemotherapy resulted in additional 0.18 QALYs (1.41 LYs) and corresponding incremental costs $163,319, resulting an ICER of $203,638 per QALY versus chemotherapy alone. The most influential factor to this model was the body weight. Probabilistic sensitivity analysis showed there was 30.5% probability that nivolumab plus ipilimumab with two cycles of chemotherapy was cost-effective at WTP values of $150,000 per QALY in the US. Subgroup analyses demonstrated that nivolumab plus ipilimumab with two cycles of chemotherapy was more cost-effective for patients with central nervous system (CNS) metastase. Conclusion: From the perspective of the US payer, nivolumab plus ipilimumab with two cycles of chemotherapy is not a cost-effective option as first-line treatment with for patients with advanced NSCLC at a WTP threshold of $150,000 per QALY.

Authors: Ambaw Maranata Dawit
Published: March 2022

Background
Genitourinary fistula is one of a public health importance in low- and middle-income countries. It causes multiple health adversities. Mainly, lack of timely and appropriate intervention such as cesarean section causes genitourinary fistula. Nevertheless, iatrogenic genitourinary fistula is a result of medical error during obstetric and gynecological surgery such as while cesarean section and hysterectomy. This study examined the trend of iatrogenic genitourinary fistula, major surgical procedures leading to iatrogenic fistula and its risk factors.
Methods
a facility based cross sectional study design was deployed. The respondents were included retrospectively using their medical history from January 2005 to December 2019 at Addis Ababa fistula hospital, Addis Ababa, Ethiopia. Data was analyzed using SPSS version 20.0 software. Annual percent change and average annual percent change were calculated using joinpoint regression analysis on joinpoint regression program version 4.8.0.1. Bivariate and multivariable regression model was also undertaken to implore the important risk factors for iatrogenic genitourinary fistula.
Results
Total 9229 fistula patients treated in the hospital. Of which 643(6.96%) and 8,586(93.03%) referred iatrogenic genitourinary fistula and obstetric fistula cases, respectively. The mean age of iatrogenic genitourinary fistula patients was 30.02 (± 4.63 SD) years, ranged 17–45 years. Among the iatrogenic genitourinary fistula cases, 341(53%) were caused by cesarean section. Other causes were errors while repairing ruptured uterus 131(20.4), during undertaking hysterectomy for ruptured uterus 78(12.1%), and while gynecological hysterectomy 93(14.5%). From 2005 to 2019, there was a significant rising trend in iatrogenic genitourinary fistula (1.55–52.9%, p < 0.001). Average annual percent change from 2005 to 2019 was 13.2% (95% CI: 7.7, 18.9). Statistically significant risk factors for iatrogenic genitourinary fistula were history of obstetric or gynecologic surgery, type of institution where the surgery conducted, and parity.
Conclusion
The trend of IGF substantially increased while the OF declined over 2005 to 2019 period. Patient safety and quality surgical procedure on pelvic surgeries is paramount important. The study also revealed that CS was the most frequent surgery resulting IGF followed by repairing ruptured uterus, hysterectomy for ruptured uterus and gynecologic hysterectomy.
Production of the Final Score Tables of the Soccer Tournaments using Functional Programming
Authors: Milani Muhammed
Published: March 2022

In sports tournaments, several teams compete with each other, and in the end, it will rank according to the final table of competitions. The results from the tournament will form the final tables. Because each match can obtain different results, a tournament can achieve different final tables. This article presents a systematic method for generating all possible scenarios for the final tables that a football tournament can achieve. In this research, we have only used the teams' results to produce the final tables, and other issues such as the number of goals scored or the goal difference have not been addressed. The proposed recursive method is suitable for functional programming and implemented using Haskell programming Language.

Published: March 2022

Predatory stink bugs are important biological control agents in agricultural and forest crops. The use of these natural enemies by companies, growers and research centers has been an important tactic to control caterpillar pest outbreaks. Podisus nigrispinus (Dallas) and Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) were kept for 24, 36, or 48 hours without food, and the time taken by theses predators for the first attack and to kill a sixth-instar Thyrinteina arnobia (Stoll) (Lepidoptera: Geometridae) larvae, as well as the number of attacks during four-hour period were evaluated. The starving periods that the predators were subjected to affect the time for the first attack and also the number of attacks. Podisus nigrispinus and B. tabidus attacked faster when kept for 36 and 48 hours without food, respectively. The time taken for the first attack was similar for all periods for both predators, but B. tabidus was faster than P. nigrispinus during all periods. Brontocoris tabibus’ constant feeding on the plant may explain its attack efficiency and capacity for controlling of the T. arnobia caterpillar, because water obtained during phytophagy is important for the process of extra-oral digestion of Asopinae predators.

Published: March 2022

Purpose Current diagnosis and treatment in psychiatry are heavily depends patients’ reports and clinician judgement, thus are sensitive to memory and subjectivity biases. On the other hand, a growing effort in developing objective markers in psychiatry may be a way to face all these challenges. Vocal acoustic features have been recently studied as objective measures, with the advantages of being accessible, inexpensive, non-invasive and remotely performed. Method The main objective of this work is to propose a methodology to support the diagnosis of major depressive disorder, bipolar disorder, schizophrenia, and generalized anxiety disorder using vocal acoustic analysis and machine learning. Seventy-eight individuals over 18 years old were recruited into five groups: 28 participants with major depressive disorder; 20 patients with schizophrenia; 15 patients with bipolar disorder; 4 patients with generalized anxiety disorder; and 12 healthy controls. ResultsRecordings were submitted to a vocal feature extraction algorithm, and to experiments using different machine learning classification techniques. Random Forests with 300 trees achieved the greatest classification performance (75.27% for accuracy, 69.08% for kappa, 75.30% for sensitivity, and 93.80% for specificity) for the simultaneous detection of major depressive disorder, schizophrenia, bipolar disorder and generalized anxiety disorder.ConclusionAs changes in vocal patterns have been reported in several mental disorders and appear to correlate with illness severity, vocal acoustic features have shown to be promising markers, with the advantages of being abundant, inexpensive, non-invasive and remotely performed. The results provided by our proposed solution support the feasibility of a computational method based on vocal parameters for assisting clinicians in patient triage and diagnosis in psychiatry.As the main contribution of this work, we present the intelligent system composed of the support vector machine and the time and frequency characteristics of the audio, which works as a digital biomarker to support the diagnosis of mental disorders in the context of psychiatric emergency.

Published: March 2022

As an improved form of fuzzy sets (FSs), spherical fuzzy sets (SFSs) could provide decision makers (DMs) with more free space to express their preference information. In this article, we first develop some Hamacher power aggregation operators (HPAOs) under the SFSs by power operators and Hamacher operators, including spherical fuzzy Hamacher power average (SFHPA) operator, spherical fuzzy Hamacher power geometric (SFHPG) operator, spherical fuzzy Hamacher power weighted average (SFHPWA) operator, spherical fuzzy Hamacher power weighted geometric (SFHPWG) operator, spherical fuzzy Hamacher power ordered weighted average (SFHPOWA) operator, spherical fuzzy Hamacher power ordered weighted geometric (SFHPOWG) operator, spherical fuzzy Hamacher power hybrid average (SFHPHA) operator and spherical fuzzy Hamacher power hybrid geometric (SFHPHG) operator. At the same time, some properties of the proposed operators are shown, and the relationships between these operators and existing operators are discussed. Furthermore, a novel spherical fuzzy entropy measure is introduced to calculate unknown attribute weights. Then, some novel multiple attribute group decision making (MAGDM) methods are established by the proposed operators as well as entropy measure under the SFSs. Lastly, the practicability of the presented methods is verified with a numerical case. Moreover, sensitivity analysis and further comparation with existing methods to demonstrate the availability and superiority of the developed methods.

Published: March 2022

A Caatinga é o bioma predominante do semiárido brasileiro e o número de áreas degradadas em seus ecossistemas vem crescendo a cada dia. Dos componentes funcionais desses ecossistemas, a produção de matéria orgânica e a reciclagem dessa matéria ainda merecem ser objetos de investigação, uma vez que elas podem refletir funcionalidade e estabilidade do ecossistema, degradação ambiental e aptidão agrícola de seus solos. Utilizando-se de caixas coletoras e de sacolas de náilon (litter bags), foram determinadas a produção e a decomposição de serrapilheira ao longo de transects, em uma área de Caatinga estruturalmente e funcionalmente preservada e outra degradada. A pesquisa teve início em 01/09/2012 e final em 06/01/2013, no Município de Cajazeirinha-PB, Brazil. Os dados foram submetidos a uma análise estatística não paramétrica, utilizando-se o teste de Kruskal Wallis, a 5% de probabilidade. A produção de serrapilheira foi maior na área preservada do que na área degradada, tendo sido as frações representadas pelas folhas, maiores do que as frações representadas pelos galhos e estas, por sua vez, maiores do que as frações representadas pelas estruturas reprodutivas, em ambas as áreas. Tanto a produção quanto a decomposição da serrapilheira variaram bastante durante os meses avaliados em função da irregularidade das chuvas, uma vez que este fator influencia positivamente os mecanismos fisiológicos das espécies vegetais e a atividade decompositora dos micro-organismos do solo. Das frações de serrapilheira, àquela representada pelas folhas foi a que mais incorporou-se ao solo durante a decomposição. Os resultados preliminares permitem concluir que a estrutura vegetacional de uma área preservada tem relação direta com sua funcionalidade. Ela contribui mais para a transferência de nutrientes da vegetação para o solo, reflete maior produtividade primária, regula o fluxo de energia e a ciclagem de nutrientes e confere maior homeostase ao ecossistema.
Quasiparticle disintegration in fermionic superfluids
Authors: Van Loon Senne , Tempere Jacques , Kurkjian Hadrien
Published: March 2022

We study the fermionic quasiparticle spectrum in a zero-temperature
superfluid Fermi gas, and in particular how it is modified by different
disintegration processes. On top of the disintegration by emission of a
collective boson (1\to21→2,
subject of a previous study, PRL , 073404), we consider here
disintegration events where three quasiparticles are emitted
(1\to31→3).
We show that both disintegration processes are described by a
tt-matrix
self-energy (as well as some highly off-resonant vacuum processes), and
we characterize the associated disintegration continua. At strong
coupling, we show that the quasiparticle spectrum is heavily distorted
near the 1\to31→3
disintegration threshold. Near the dispersion minimum, where the
quasiparticles remain well-defined, the main effect of the off-shell
disintegration processes is to shift the location of the minimum by a
value that corresponds to the Hartree shift in the BCS limit. With our
approximation of the self-energy, the correction to the energy gap with
respect to the mean-field result however remains small, in contrast with
experimental measurements.

Published: March 2022

In Indonesia, where most business organizations are family-owned, culture influences family employees’ behavior. Filial piety, or honoring the seniors, is considered a significant cultural value that motivates the family employees to be committed to the business. This study aims to test the effect of filial piety on identity alignment, career interest alignment, and affective commitment. Quantitative analysis is conducted to test the hypotheses of this study using purposive sampling based on questionnaire survey responses from 270 junior family business employees. The study employs Partial Least Square-Structural Equation Modelling (PLS-SEM) analysis with the SmartPLS software to test the hypotheses. The test result shows that: 1) filial piety has a positive effect on identity alignment and career interest alignment, 2) identity alignment has a positive effect on affective commitment, and 3) career interest alignment has a positive effect on affective commitment. The study illustrates how filial piety affects junior family employee behavior, an issue that has not been addressed before in Asian family business studies.

Published: March 2022

Dil öğretimi, belli bir sistematik yapı çerçevesinde gerçekleştirilerek öğrenici dört temel beceriyle de desteklendiği takdirde başarılı bir sonuç elde edilebilir. Özellikle de yabancı dil öğretiminde bu sistematik yapı daha büyük bir önem kazanır. Bu yapının da homojen bir şekilde sağlanabileceği temel materyal ders kitaplarıdır. Bu nedenle ders kitaplarının içeriği oluşturulurken büyük bir özen ve dikkat gösterilmesi gerekir. Yabancı dil öğretimi kitaplarında içerik oluşturulurken, metinler ve etkinlikler hazırlanırken kültür aktarımının da sağlanmasına dikkat edilmesi gerekmektedir. Bu bağlamda söz konusu ders kitaplarında hem dili öğretmek hem hedef dilin kültürünü tanıtmak hem de kaynak kültürle hedef kültür arasında etkileşimi sağlayabilmek için en önemli aracın metinler olduğunu söylemek mümkündür. Özellikle yazınsal metinler bu etkileşimi sağlayan önemli araçlardır. Yazınsal metin ifadesiyle masal, efsane, hikâye, mesnevi, şiir, fıkra, roman gibi Türk edebiyatının birçok dönemini kapsayan metinler akla gelmektedir.

BLS quarterly estimates of labor productivity, or output per hour worked, are revised as more data become available and seasonal factors are updated. BLS publishes three regularly scheduled estimates of labor productivity growth: the preliminary estimates, the first revised estimates, and the second revised estimates. Most of the revisions result from updates to source data. This article analyzes revisions to the preliminary and first revised estimates relative to the second revised estimates and describes the new BLS methodology for constructing intervals that better informs data users about the likely size of future revisions. As part of our analysis, we identify the sources of revisions and determine whether systematic patterns exist that could be exploited to construct intervals. We find no evidence of such trends or systematic patterns.

Sidoharjo village has natural resources that can be used to increase the community welfare. The village government has formed BUMDes in an effort to improve the welfare of the community. However, the BUMDes has not yet played an optimal role in community empowerment. There is no synergy between the activities of the village government, business actors, and BUMDes so that the management of resources has not had an impact on improving the welfare of village communities. The solution offered in Community Service activities is identification and mapping the potential natural resources in Sidoharjo. The result of this activity can be used as source data to plan new business unit in BUMDes. Thus it is hoped that BUMDes can emerge as one of the new economic forces based on local potential in Sidoharjo Village. Mapping the natural resource of the village begins with a number of discussions with village officials, tourism awareness groups, and businesses to get preliminary data on existing problems. Then the survey is carried out in several stages to get the latest data on the potential of existing resources. The results of the activities in the form of village potential manuscripts and also tourism potential videos are expected to be used as preliminary data for planning the development of new business units under the management of BUMDes so that the utilization of natural resource potential is more optimal. It is hoped that this will drive the economy in Sidoharjo Village, which has an impact on improving community welfare.

Abstract: cardiac arrhythmia is a heart condition in which there will be irregularity of the heart beat. This project aims to detect and classify arrhythmia into 14 different variants. Mainly there are two types of cardiac Arrythmia-Tachycardia in which heart rhythm will beat with a rate of more than 100 beats per minute. Bradycardia in which heart rhythm will be slow with a rate below 60 beats per minute. IN this work we use the several machine algorithms like SVM , random forest many other algorithms ,we will try get the highest accuracy by using different machine learning tools in three steps we can do the prediction of the cardiac arrhythmia, we will train the data by using different machine learning algorithms In the second stage upload the model into our Arduino and start predicting real ECG signal which get from the ECG sensor we are using, then the proposed system will send the signal and the prediction results to the mobile application and it stores it on the cloud for the easy access by the user or doctor Keywords: Cardiac Arrythmia, Tachycardia, Bradycardia, ECG sensor, Machine Learning
Corporeality (BR): A Weakly-supervised Object Detection Approach with 3D Shape-guided Label Enhancement
Authors: Mondal Bidisha
Published: March 2022

Abstract: This paper, proposes a weakly-supervised approach for three-dimensional object detection, which makes it possible to train a strong three-dimensional detector with position-level based annotations (i.e. an- notations pertaining to the centre of an object). In an attempt to rectify this information loss from box annotations to object centres, the proposed method, named Corporeality (referred to as BR in short in image and tabular representations) makes use of synthetic three-dimensional shapes to convert weak labels into completely annotated virtual scenes as stronger supervision, and then in turn utilizes these perfect virtual labels to complement and refine the original set of labels. The process involves the assemblage of three-dimensional shapes into physically reasonable virtual scenes according to the coarse scene layout extracted from position-level based annotations previously. Then we go back to reality by applying a virtual-to-real do-main adaptation function, which refines the weak labels along with supervising the three-dimensional detector’s training with the virtual scenes. This paper further proposes a more challenging benchmark for three-dimensional object detection with more diverse object sizes to better emphasize the potential of Corporeality. With an investment of a meagre 5% labelling labour, Corporeality was able to perform competitively when compared with some of the popular fully-supervised approaches out there, widely used with ScanNet datasets.
