Published: September 2022

The background of this research is that there are still many Islamic educations in Indonesia that have not actualized the moral education contained in the source of Islamic teachings, namely the Koran. So this study aims to analyze the moral education contained in Surah Al-Hujurat/49 and connect it with moral education with Islamic educational institutions. The results of this study are expected to add new perspectives in order to apply them to the world of Islamic education contained in the Koran. The results of this study indicate that: 1) There is moral education in Surah Al-Hujurat, namely: First, moral education to Allah includes loving Allah more than loving anyone else by using Allah's word in the Qur'an as a guide and guidance in life, carrying out all his commands. and always leave His prohibitions and ask forgiveness from Allah swt. Second, moral education to the Apostle, namely giving birth to an attitude of gentle speech when together with the Apostle, and imitating his attitudes in doing in everyday life. Third, the moral education of fellow human beings, namely, all fellow human beings must always be kind in responding to information, resolve disputes between Muslims, and are not allowed to call with bad names and find fault with others.

This is the additional part to the already submitted paper "The PRODUCTION and TRANSITION of ENERGY from the SOURCES to EM WAVES. DECODING the PLANCK CONSTANT. The MEANING of SYSTEM’S MASS, and the TRANSITION of ENERGY, NOT MASS" FRAGMENTS from my NEXT BOOK CHAPTER 2. MATTER – MASS and its PROPERTIES: WEIGHT, VELOCITY and ENERGY
Authors: VAYNSHTEYN RITA
Published: September 2022

In order to solve the problem of motion, it is necessary to separate the concept of mass from the concept of weight and decide when the mass bears weight. There isn’t any weight within any system: pressure due to the spatial volume of the systems exists, but the weight is absent. In the own outer space of any celestial body, any freely falling body acquires an acceleration of space and gets the weight relative to the acceleration of that space, if we neglect the presence of atmosphere. Forces never generate alone but only in their interaction. A motion of two relative units of matter interacts with a definite force.We can use such notions as a space and time only as a result of the motion. Space and time are interconnected entities and they make sense according to a certain motion of the matter only.

CNN-Based Optical Character Recognition for Isolated Printed Gujarati Characters and Handwritten Numerals
Authors: Suthar Sanket B. , Thakkar Amit R.
Published: September 2022

Optical character recognition (OCR) technologies have made significant progress in the field of language recognition. Gujarati is a more difficult language to recognize compared to other languages because of curves, close loops, the inclusion of modifiers, and the presence of joint characters. So great effort has been laid into the literature for Gujarati OCR. Recently deep learning-based CNN models are applied to develop OCR for different languages but Convolutional Neural Networks (CNN) models are not yet giving a satisfactory performance to recognize Gujarati characters. So, this paper proposes a revolutionary Gujarati printed characters and numerals recognition CNN models. CNN-PGC (CNN for - Printed Gujarati Character) and CNN-HGC (CNN for - Handwritten Gujarati Character) are two optimally configured Convolutional Neural Networks (CNNs) presented in this research for printed Gujarati base characters and handwritten numbers, respectively. Concerning particular performance indicators, the suggested work's performance is evaluated and proven against that of other traditional models and with the latest baseline methods. Experimental analysis has been carried out on well-segmented newly generated Gujarati base characters and numerals dataset which includes 36 consonants, 13 vowels, and 10 handwritten numerals. Variation in the database is also taken into consideration during experiments like size, skew, noise blue, etc. Even in the presence of printing irregularities, writing irregularities, and degradations the proposed method achieves a 98.08% recognition rate for print characters and a 95.24 % recognition rate for handwritten numerals which is better than other existing models.

Cloud-Computing offers high performance solution to solve complex engineering and scientific tasks by deploying resources at geo-diverse locations. With the large-scale demand of scientific and engineering jobs, huge number of cloud data centres needs to be constructed to fulfil the requirement of the jobs. The extensive use of cloud data centres leads to increases in cost as well as energy consumption. In this paper, an agent based Cost-Effective Energy Efficient scheduling algorithm, namely, CEEE has been proposed. To establish the effectiveness of the proposed algorithm, simulation is performed on CloudSim environment. The proposed algorithm is compared with state of art scheduling algorithms namely, Randam and MaxUtil. The experimental results demonstrates that CEEE algorithm is capable of refining energy efficiency with reduced cost. The proposed algorithm outperforms the prevailing algorithms in terms of energy consumption, resource utilization, number of hosts in sleep mode and completion time.

Exercise-induced bronchoconstriction in university field hockey athletes: Prevalence, sex differences, and associations with dyspnea symptoms
Authors: Needham Robert S. , Sharpe Graham R. , Williams Neil C. , Lester Paul A. , Johnson Michael A.
Published: September 2022

Introduction

Exercise-induced bronchoconstriction (EIB) is a prevalent condition in athletes. EIB screening studies identify many athletes with undiagnosed EIB. Moreover, there is a poor relationship between EIB and dyspnea symptoms recalled from memory.

Purpose

This study investigated: (I) the prevalence of EIB in British university field hockey athletes; (II) the effect of sex and diagnostic criteria on EIB prevalence; and (III) the association between EIB and contemporaneous dyspnea symptoms.

Methods

52 field hockey athletes (age: 20 ± 2 years; height: 173 ± 9 cm; body mass: 72 ± 10 kg; male = 31; female = 22) completed a eucapnic voluntary hyperpnea (EVH) test with multi-dimensional dyspnea scores measured 3–10 mins post-EVH. A test was deemed positive (EIB+) if a fall index (FI) ≥10% in FEV1 occurred at two consecutive time points post-test (FIATS). Two further criteria were used to assess the effect of diagnostic criteria on prevalence: FI≥10%, determined by a pre-to-post-EVH fall in FEV1 of ≥10% at any single time-point; and FI≥10%−NORM calculated as FI≥10% but with the fall in FEV1 normalized to the mean ventilation achieved during EVH.

Results

EIB prevalence was 19% and greater in males (30%) than females (5%). In EIB+ athletes, 66% did not have a previous diagnosis of EIB or asthma and were untreated. Prevalence was significantly influenced by diagnostic criteria (P = 0.002) ranging from 19% (FIATS) to 38% (FI≥10%−NORM). Dyspnea symptoms were higher in EIB+ athletes (P ≤ 0.031), produced significant area under the curve for receive operator characteristics (AUC ≥ 0.778, P ≤ 0.011) and had high negative prediction values (≥96%).

Conclusion

Overall, 19% of university field hockey athletes had EIB, and most were previously undiagnosed and untreated. EVH test diagnostic criteria significantly influences prevalence rates, thus future studies should adopt the ATS criteria (FIATS). Contemporaneous dyspnea symptoms were associated with bronchoconstriction and had high negative prediction values. Therefore, contemporaneous dyspnea scores may provide a useful tool in excluding a diagnosis of EIB.
Carrier-free supramolecular nanoassemblies of pure LSD1 inhibitor for effective anti-tumor therapy
Authors: Li Boao , Zhang Xiangyu , Li Jibin
Published: September 2022

The LSD1 protein is an oxidase that regulates protein methylation, which regulates gene expression and triggers tumors. Previously, inhibiting LSD1 has been found to be an effective treatment strategy for opposing tumors caused by overexpression of LSD1. Our recent study found that compound 17i was a suitable LSD1 inhibitor with potential anti-tumor activity. However, its extremely insoluble nature limits further validation of its anti-tumor activity at the clinical level. In this study, a unique carrier-free supramolecular nanoassemblies of pure compound 17i is expected to enhance therapeutic efficacy. Aqueous-insoluble compound 17i was mixed with a small quantity of DSPE-PEG2000 into an organic solvent and was prepared as nanoassemblies in water via the one-step nanoprecipitation method. The 17i nanoassemblies have a similar effect on its cytotoxicity when compared with 17i solution in vitro. Importantly, the PEGylated 17i nanoassemblies exhibit significant superiorities over 17i solutions in therapeutic efficiency, anti-tumor immune response and systemic toxicity in BALB/c mice bearing CT-26 colorectal tumors. We envision that the fabrication of pure drug nanoassemblies offers an efficient platform for reforming the undesirable characteristics of drug-like compounds to potentiate the anti-tumor therapeutic effect.

Published: September 2022

Abstract: A mixed-dimensional V2CTx/Ti3C2Tx composite interlayer was successfully prepared to tackle severe polysulfide (LiPS) shuttling and sluggish sulfur redox kinetics for high-performance lithium–sulfur batteries. In the unique nanoarchitecture, two-dimensional Ti3C2Tx nanosheets served as a stable skeleton with superb electronic conductivity, good mechanical strength, and high polysulfide adsorption, whereas one-dimensional V2CTx nanorods played a crucial role in chemisorbing LiPSs and catalyzing the conversion of LiPSs due to their high polarity and electrocatalysis. With the synergistic effect of V2CTx and Ti3C2Tx composite nanostructures, the cells with the mixed-dimensional V2CTx/Ti3C2Tx composite interlayer showed an impressive long-term cycling stability and small capacity decay rate of 0.062% per cycle over 600 cycles at 1 C and exhibited an outstanding rate capability of 935.3 mAh·g−1 at 2 C.
Superwetting membrane-based strategy for high-flux enrichment of ethanol from ethanol/water mixture
Authors: Wei Zhongwei , Zhang Shaoqing , Chang Li , Liu Hongliang , Jiang Lei
Published: September 2022

Ethanol, which can be scalable produced from fermented plant materials, is a promising candidate to gasoline as the next-generation liquid fuel. As an energy-efficient alternative to distillation, membrane-based strategies including pervaporation and reverse osmosis have been developed to recover ethanol from fermentation broths. However, these approaches suffer the drawback of low separation flux. Herein, we report a superwetting membrane system to enrich ethanol from water in a high-flux manner. By synergistically regulating surface energy of the solid porous membrane and hydration between an additive inorganic potassium salt and water, concentrated ethanol can rapidly wetting and permeate the porous membrane, with the salt solution being blocked. Using this newly developed superwetting membrane system, we can achieve fast enrichment of ethanol from water, with flux of two orders magnitude higher than that of pervaporation and reverse osmosis membranes.
Criteria for differentiating left bundle branch pacing and left ventricular septal pacing: A systematic review
Authors: Zhu Kailun , Li Linlin , Liu Jianghai , Chang Dong , Li Qiang
Published: September 2022

Background

As a novel physiological pacing technique, left bundle branch pacing (LBBP) can preserve the left ventricular (LV) electrical and mechanical synchronization by directly capturing left bundle branch (LBB). Approximately 60–90% of LBBP were confirmed to have captured LBB during implantation, implying that up to one-third of LBBP is actually left ventricular septal pacing (LVSP). LBB capture is critical for distinguishing LBBP from LVSP.

Methods and results

A total of 15 articles were included in the analysis by searching PubMed, EMBASE, Web of Science, and the Cochrane Library database till August 2022. Comparisons of paced QRS duration between LVSP and LBBP have not been uniformly concluded, but the stimulus artifact to LV activation time in lead V5 or V6 (Stim-LVAT) was shorter in LBBP than LVSP in all studies. Stim-LVAT was used to determine LBB capture with a sensitivity of 76–95.2% and specificity of 78.8–100%, which varied across patient populations.

Conclusion

The output-dependent QRS transition from non-selective LBBP to selective LBBP or LVSP is direct evidence of LBB capture. LBB potential combined with short Stim-LVAT can predict LBB capture better. Personalized criteria rather than a fixed value of Stim-LVAT are necessary to confirm LBB capture in different populations, especially in patients with LBB block or heart failure.

Published: September 2022

Objectives

We aimed to evaluate the feasibility of left ventricular electroanatomical mapping to choose between left bundle branch area pacing (LBBAP) or coronary venous pacing (CVP).

Background

There are several ways to achieve left ventricular activation in cardiac resynchronization therapy (CRT): LBBAP and CVP are two possible methods of delivering CRT. However, the criteria for choosing the best approach remains unknown.

Methods

A total of 71 patients with heart failure, reduced ejection fraction, and left bundle branch block (LBBB) were recruited, of which 38 patients underwent the three-dimensional electroanatomical mapping of the left ventricle to accurately assess whether the left bundle branch was blocked and the block level, while the remaining 33 patients were not mapped. Patients with true LBBB achieved CRT by LBBAP, while patients with pseudo-LBBB achieved CRT by CVP. After a mean follow-up of 6 months and 1 year, the QRS duration and transthoracic echocardiography, including mechanical synchrony indices, were evaluated.

Results

Twenty-five patients with true LBBB received LBBAP, while 13 without true LBBB received CVP. Seventeen patients received LBBAP, and 16 patients received CVP without mapping. Paced QRS duration after the implantation of LBBAP and CVP was significantly narrower in the mapping subgroup compared to the non-mapping subgroup. A significant increase in post-implantation left ventricular ejection fraction was observed in patients with LBBAP or CVP, and the mapping subgroup were better than the non-mapping subgroup. After a 12-month follow-up, atrioventricular, intraventricular, and biventricular synchronization were significantly improved in the mapping subgroup compared to non-mapping groups in both LBBAP and CVP.

Conclusion

In our study, three-dimensional electroanatomical mapping was used to choose LBBAP or CVP for heart failure patients, which proved feasible, with better cardiac resynchronization in the long-term follow-up. Therefore, three-dimensional electroanatomical mapping before CRT appears to be a reliable method for heart failure patients with LBBB who are indicated for CRT.
The role of gender in providing expert advice on cyber conflict and artificial intelligence for military personnel
Authors: Fisher Kelly
Published: September 2022

This article draws upon original qualitative interview data with Norwegian male and female cyberengineer cadets at the Norwegian Cyber Defense Academy, who could in the future be working with AI-enabled systems in a variety of positions throughout the Norwegian military. The interviews explored how these cadets feel they as cyberengineers will be perceived in their future positions in the military, what challenges they feel they may face, and how gender may play a role in this. Different cyberengineers expressed concern about being able to communicate the cyber domain to their non-technology specialist colleagues due to the increasing complexity of new technologies. Gender appeared to be playing a role in this concern as the women interviewed expressed specific concerns that they feel as women, that they do not fit the stereotype of who is a cyberengineer, while some of the men felt that as cyberengineers they were seen as embodying a nerd masculinity, and that these gendered perceptions has implications for how they feel others perceive their competence levels. The findings from this article highlights gendered hierarchies in the military and the need for military institutions to focus on developing communication skills among those working with cyber operations. As the role of cyber is expected to grow in military operations, cyberengineers will need to find ways of communicating effectively with non-specialists—especially as complex AI-enabled systems are introduced. Finally, this paper argues the need for military institutions to take gender into account for this training and need for gender-sensitive policies.

Published: September 2022

The influence of teachers’ commitment and burnout on student learning outcomes and their performance requires astute research to identify the antecedent factors of these two variables. Commitment and burnout are peremptorily related to the positive and negative aspects of performance, respectively. Most of the previous research showed inconsistency; therefore, a new assay is needed to produce more convincing findings. This study aims to identify the antecedent variables of teachers’ commitment and job burnout by using meaning at work as a mediating variable. Based on the convenience sampling technique, 304 respondents were selected among the teachers in private primary and secondary education levels in the East Kalimantan Province, Indonesia. A structural equation model (SEM) was used in the data analysis. The results showed that school support, self-actualization, and meaning at work were antecedent variables for teachers’ commitment and burnout. The meaning at work also mediates the relationship between school support and self-actualization. Meanwhile, the remaining four mediating roles were not proven in this research. These findings offer a framework for principals to increase commitment and reduce teachers’ burnout by increasing school support and self-actualization through meaning at work.

Published: September 2022

Technology-based supports offer promise for helping elementary school teachers implement Tier 2 interventions to address challenging student behavior. The Daily Report Card Online (DRCO) platform is a cloud-based web application designed to support teachers’ adoption and implementation of a high-quality daily report card (DRC) intervention through the use of professional development resources, guided intervention design workflows, algorithm-based decision-making tools, and real-time progress monitoring. We examined teacher adoption, adaptation, and implementation of a DRC intervention when using the DRCO platform with support from a consultant during the 2021–2022 school year. Participants were 29 teachers, 20 of whom used the DRCO to implement a DRC with a student (n = 20). The most frequently chosen target behaviors were student interruptions, non-compliance, and work completion. When using the DRCO platform, teachers achieved several procedures that align with evidence-based guidelines (e.g., screening, baseline tracking, setting achievable goals, tracking behaviors over time). However, goal criterion changes and shaping procedures were used less often than expected. Despite the option to track behaviors solely with technology, 60% of teachers tracked student behaviors via paper methods (e.g., printed the DRC card, used sticky notes). Adaptations were made by 40% teachers; however, all adaptations involved modifying printed materials to be more student-friendly (e.g., add clipart to the DRC) and did not change the guiding principles of the intervention. Tau-effect sizes for academic and behavioral target behaviors on the DRC showed small to moderate change over time and change in target behaviors showed some association with change in global teacher ratings. Lastly, we identified associations between teacher characteristics and adoption and implementation, as well as associations between implementation and student outcomes.

Published: September 2022

Polycystic ovary syndrome is an endocrinopathy that mainly affects adolescent girls and young women of childbearing age. In girls, the presence of clinical and biochemical symptoms of hyperandrogenism should be particularly considered. The role of vitamin D deficiency in insulin resistance, inflammation, dyslipidemia, and obesity, i.e. in diseases associated with PCOS, has been investigated, which may suggest its involvement in the pathophysiology of the syndrome. Leptin has been shown to stimulate the formation of FGF23 in bones. There is a relationship between the incidence of dyslipidemia, adipose tissue mass and the concentration of fibroblast growth factor 23. The main aim of the presented research project is to assess the concentration of vitamin D, calcium, and selected hormones as well as the concentration of adipokines (leptin) in girls diagnosed with polycystic ovary syndrome.

Materials and methods

The study included a population of 85 girls and young women aged 14 to 22 years. The study group included 37 girls who were diagnosed with polycystic ovary syndrome according to the modified Rotterdam’s criteria. The control group consisted of 48 completely healthy girls. In the first stage of the study participants were required to answer background questions. Next, anthropometric measurements were performed. The laboratory tests assessed: leptin, FGF23, FSH, SHGB, total testosterone, DHEA-S, 25-OH-D3, PTH, calcium, androstadiene, AMH, glucose, insulin.

Results

The vitamin D level in the group with polycystic ovary syndrome was lower than in the control group, but there was no statistically significant difference. The level of anti-Müllerian hormone was significantly higher in the group of girls diagnosed with PCOS compared to the control group. Statistically significant differences between both groups were also noted in the HOMA-IR value. The concentration of calcium, parathyroid hormone, FGF23 and leptin in the study and control groups showed no statistically significant difference.

Conclusions

In the studied group of girls with PCOS, no correlation between the level of vitamin D and selected parameters such as: AMH leptin, HOMA-IR and FGF23 was confirmed. On this basis, it can be assumed that additional vitamin D supplementation would not reduce the symptoms of polycystic ovary syndrome.

Published: September 2022

As the lifeline of energy supply for various offshore projects, accurately evaluating and predicting the operation status of submarine cables are the foundation for the reliable operation of energy systems. Based on fully mining the dynamic and static characteristics of submarine cable operation and maintenance data, this paper proposes a submarine cable operation status prediction method based on a convolutional neural network—bidirectional gated recurrent unit (CNN-BiGRU) integrating attention mechanism. Firstly, the evaluation index system of the submarine cable operation status is established by considering three key influencing factors including online monitoring, routine inspection, and static test. Then, the operation condition evaluation model for submarine cable is constructed based on the cooperative game theory and the multi-level variable weight evaluation. Finally, the CNN-BiGRU combined neural network model integrating the attention mechanism is established, and the historical operation data and condition quantification results (health value) are used as input characteristic parameters to predict the evolution trend of the operation status of the submarine cable. The case study shows that the proposed method can effectively predict the operation status of submarine cables, and the root mean square error of the prediction is as low as 1.36%, which demonstrates the superior performance compared with the back propagation (BP) neural network, CNN, long short-term memory (LSTM), CNN-LSTM, and other algorithms.
Analysis of fuel performance under normal operation conditions of MicroURANUS: Micro long-life lead-bismuth-cooled fast reactor
Authors: Mun Jiwon , Kim Hyeong-Jin , Ryu Ho Jin
Published: September 2022

An innovative ultra-long-life lead-bismuth eutectic (LBE)-cooled fast reactor called MicroURANUS has been designed to prevent severe accidents. It utilizes the remarkable natural circulation capability of the LBE coolant. Furthermore, it can be operated at 60 MWth without refueling for 30 effective full-power years (EFPY). In this study, the thermal and mechanical performance of the highest linear power rod of MicroURANUS was evaluated by modifying the fuel performance code FRAPCON-4.0, which is the normal operation fuel performance code for light water reactors (LWRs). A plutonium generation model was added to consider changes in the physical properties of the UO2 fuel. Furthermore, mechanical and oxidation models of 15–15Ti were added, and the coolant models were modified for liquid metal. According to the unique design of MicroURANUS, a maximum low linear power density of 12.5 kW/m ensures that the highest linear power rod can operate below the safety limit. A low fuel temperature provides a large safety margin for fuel melting, as well as low-pressure build-up fission gas release. In addition, low inlet and outlet coolant temperatures of 250 and 350°C cause the cladding to display a low degree of swelling (a maximum diametral strain of 1.5%) while maintaining high mechanical integrity with negligible cumulative damage fraction (CDF). The modified fuel performance code for lead-cooled fast reactors exhibited the capability to be utilized for fuel performance evaluation and design feedback of MicroURANUS.

The pump performance at various flow rates obtained numerically are compared with the theoretically results. The deterioration in pump performance at various flow rates were investigated to find the losses associated with the design of the pump components. The stage-wise performance analysis revealed the hydraulic losses associated with the second-stage impeller due to highly swirled flow exiting from the first stage twin-volute. The fluid exiting the twin-volute have a high circumferential velocity than its radial component leading to a high pre-swirl at the inlet of stage 2 impeller. In order to regulate the high pre-swirl, baffle plates were installed at the exit of the twin-volute. Three baffle plate configurations were studied and their effects on the pump performances were compared. The vertical configuration improved the pump efficiency by 1.36% and head by 6.04% while the horizontal configuration improved them by 2.42% and 5.96% respectively. The 4-plate baffle configuration improved the pump performance by only a small margin. The installation of the baffle plates also improved the stage performances in both design and off-design conditions. The horizontally installed baffle plates were then tested at various angles. The plates installed at 300° clock-wise increased the pump head by 9.08% and efficiency by 3.87%. A comprehensive analysis of the flow physics inside the pump are also presented.

This study focuses on exploring the relationship between industrial intelligence and capacity utilization based on the perspective of green development. Based on a fixed effect model, using data from the International Federation of Robotics (IFR) and China’s A-share listed enterprises from 2011 to 2019, this study empirically analyzes the influence of industrial intelligence on enterprises’ capacity utilization. The benchmark regression results reveal that industrial intelligence has a negative effect on enterprises’ capacity utilization. The results are robust to several econometric concerns. Moreover, mechanism analysis indicates that industrial intelligence affects enterprises’ capacity utilization through the productivity effect, the green innovation effect, and the scale expansion effect. When considering the heterogeneity at regional levels, we find that enterprises in the central and western regions are more affected by industrial intelligence. Our findings provide guidance to enterprises and policymakers in addressing industrial overcapacity and green development issues in China.

Mining provides basic materials and energy for human life and supports economic and social prosperity and development. The decoupling of mining carbon emissions from economic development is an important way of achieving China’s carbon peaking and carbon neutrality goals. This study uses the Tapio decoupling model to measure the relationship between China’s economic development and carbon emissions from 2001 to 2018. It analyzes the overall industry as well as its subdivisions and identifies the factors driving carbon emissions with help from the improved Kaya identity and LMDI decomposition models. The results show that, except for the unstable situation in the oil and natural gas mining industry, the other mining divisions have attained strong decoupling and have become stable, showing a continuous positive trend. On the whole, the mining product smelting and processing industry has achieved a major transformation, moving from negative decoupling to weak decoupling, but there are great differences between different sub-sectors. The overall consumption of China’s mining products, and the incremental carbon emissions have continued to decline, while economic development has shifted from inefficient expansion to high-quality economic development, although without reaching the ideal state. The economic factor and energy intensity effects are the key factors in increasing and restraining carbon emissions, respectively, and their influence should not be ignored. This study aims to provide a decision-making basis for China’s mining industry, that it might carry out carbon emission reduction planning, and promote the clean and efficient construction of the industry and the green and high-quality development of the economy.

Chemical industry is an important pillar industry of China’s economy with high energy consumption and carbon emissions. In the context of “peaking carbon emissions and carbon neutrality” target in China, it is imperative for the chemical industry to reduce carbon emissions. Based on literature on carbon emission reduction path and the analysis of the development status of chemical industry, this paper identifies the opportunities and challenges of carbon emission reduction in the chemical industry and proposes several feasible paths for China’s chemical industry to achieve carbon neutrality.

Complex genetic and phenotypic relationships are theorized to link different fitness components but revealing the correlations occurring among disparate traits requires large datasets of pedigreed populations. In particular, the association between traits beneficial to social dominance with health and fitness could be antagonistic, because of trade-offs, or positive, because of greater resource acquisition by dominant individuals. Studies investigating these relationships found some empirical evidence in support of both theories, mainly using multiple trait models (MTM). However, if a trait giving a social advantage is suspected to affect the expression of other traits, MTM could provide some bias, that structural equation models (SEM) could highlight. We used Aosta Chestnut-Black Pied cattle to investigate whether the fighting ability of cows (the capability of winning social dominance interactions) is genetically correlated with health and fitness traits. We ran both MTM and SEM using a Gibbs sampling algorithm to disentangle the possible causal effects of fighting ability from the genetic correlations that this trait shares with other traits: individual milk yield, somatic cells (representing mammary health), fertility, and longevity. We found antagonistic genetic correlations, similar under both approaches, for fighting ability vs. milk, somatic cells, and fertility, Accordingly, we found only a slight causal effects of fighting ability on these traits (–0.012 to 0.059 in standardized value). However, we found genetic correlations opposite in sign between fighting ability and longevity under MTM (0.237) and SEM (–0.183), suggesting a strong causal effect (0.386 standardized) of fighting ability on longevity. In other words, MTM found a positive correlation between longevity and fighting ability, while SEM found a negative correlation. The explanation could be that for economic reasons dominant cows are kept in this population for longer, thus attaining greater longevity: using MTM, the economic importance of competitions probably covers the true genetic correlation among traits. This artificially simulates a natural situation where an antagonistic genetic correlation between longevity and fighting ability appears positive under MTM due to a non-genetic advantage obtained by the best fighters. The use of SEM to properly assess the relationships among traits is suggested in both evolutionary studies and animal breeding.

Non-obstructive azoospermia (NOA) is a severe factor of male infertility; it affects approximately 1% of the global male population and accounts for 40% of male infertility cases. However, the majority of NOA cases remain idiopathic. This is the first study using whole-exome sequencing (WES) to identify a novel missense mutation in the DND1 gene (c.212A>C, p. E71A) from a Pakistani family, that includes three males with NOA. This mutation is predicted to cause DND1 protein misfolding and weaken the DND1 interaction with NANOS2, a significant regulator in primordial germ cell development. Our study identified a DND1 pathogenic mutation in NOA patients and highlighted its critical role in male fertility in humans.

Tandem mass spectrometry (MS/MS) has been developed as one of the most important diagnostic platforms for the early detection and screening of inherited metabolic disorders (IMDs). To determine the disease spectrum and genetic characteristics of IMDs in Suqian city of Jiangsu province in the northern Chinese population, dried blood spots from 2,04,604 newborns, were assessed for IMDs by MS/MS from January 2016 to November 2020. Suspected positive patients were diagnosed through next-generation sequencing (NGS) and validated by Sanger sequencing. One hundred patients with IMDs were diagnosed, resulting in an overall incidence of 1/2,046, of which 56 (1/3,653), 22 (1/9,300), and 22 (1/9,300) were confirmed amino acids disorders (AAs), organic acids disorders (OAs), fatty acid oxidation disorders (FAODs) positive cases, respectively. The highest incidence of IMDs is phenylalanine hydroxylase deficiency (PAHD) (45 cases), with a total incidence of 1:4,546. Hot spot mutations in phenylalanine hydroxylase (PAH)-related genes are c.158G > A (24.44%), c.728G > A (16.67%), c.611A > G (7.78%), and c.331C>T (7.78%). The related hot spot mutation of the MMACHC gene is c.609G > A (45.45%). Short-chain acyl-CoA dehydrogenase deficiency (SCAD)-related ACADS gene hotspot mutations are c.164C > T (33.33%) and c.1031A > G (33.33%). Our work indicated that the overall incidence of IMDs is high, and the mutations in PAH, ACADS, and MMACHC genes are the leading causes of IMDs in Suqian city. The incidence of AAs in Suqian city is higher than in other Chinese areas. The disease spectrum and genetic backgrounds were elucidated, contributing to the treatment and prenatal genetic counseling of these disorders in this region.
