The Influence of Audit Evidence Framing on Auditors’ Judgment
Authors: Vinson Jeremy M. , Pike Byron J. , Chui Lawrence , Zhou Mingjun
Published: August 2023

Framing effects are a phenomenon where individuals respond differently to equivalent information presented in a positive or negative manner. Whether framing effects within audit evidence affect auditor judgment is unknown. We conduct a simulated client inquiry experiment to investigate whether the framing of an inquiry evidence item (positive versus negative) and the timing of the frame within the inquiry evidence series (at the beginning versus end) influences auditor judgment. More consistent with attribute framing than belief-adjustment predictions, our findings suggest a primacy effect where participants who receive a positive frame at the beginning of the inquiry are less likely to change their initial assessments of misstatement than participants who receive a “neutral” perspective (i.e., both positive and negative frames simultaneously). Our results imply that positively framed initial evidence, relative to other settings, may constrain auditors’ consideration of subsequent evidence when making judgments about the account in question.

ELPR: A New Measure of Capital Adequacy for Commercial Banks
Authors: Lee Charles M. C. , Wang Yanruo , Zhong Qinlin
Published: August 2023

We develop and evaluate an accounting-based Loan Portfolio Risk (LPR) variable that captures time-varying contagion effects in default risk for a portfolio of bank loans. Our results show that an Equity-to-LPR ratio (ELPR) is additive in predicting bank failure up to five years in advance, after controlling for all the capital adequacy, asset quality, management experience, earnings, liquidity, and sensitivity to market risks (CAMELS) variables as well as other fundamental-based bank risk measures from prior studies. Further, we find that publicly listed banks with higher ELPR have lower market-implied costs of capital, especially under market stress conditions. We conclude that ELPR captures key aspects of bank risk that are missing in current Basel Committee risk-weighted-asset calculations.

Application of Fuzzy Analytic Hierarchy Process (FAHP) to Improve Precision and Certainty on Safety Conformity Evaluation in a Bottling Plant
Authors: Sawyerr Babatunde Alade , Fasina Ebun , Adedeji Wasiu Oyediran , Martins Shedrach Aliakwe , Rajan John , Oke Sunday Ayoola
Published: August 2023

With the bottling plant facing safety impacts, the commitment toward zero levels of accidents needs to be evaluated. However, the perception and measurement of safety conformity by the safety manager that is subjected to imprecision and uncertainty are hardly evaluated correctly with the present dominant approach of using crisp numeric values. This article presents a fuzzy analytic hierarchy process (FAHP) approach to reduce the imprecision and uncertainty in the safety conformity multicriteria decision-making results. The method establishes and selects the best safety conformity factors in alignment with different criteria within the segments of a Nigerian bottling plant. The fuzzy synthetic extent concerning each alternative, the degree of possibility, prioritizing weights, and the choice of the best criterion were judged based on the maximum weight in the FAHP evaluation process. The average weight criterion was used to distinguish the best from the worst units within each segment. The results reveal the criteria weights as 0.4937 for haulage drillers (warehouse), 0.3038 for palletizers (manufacturing corridor), 0.3333 for syrup mixers/lab technicians for quality assurance, and no choice of the best parameter for the fleet workshop. However, the highest weight for the contractors is 0.3201, which is for contractor 1. To compare the best and worst criteria in the present study and a literature source, the optimal criteria choices of safety conformity conflicted in all the segments. The principal difference between the present method and the analytic hierarchy process approach is integrating fuzzy application to the analytical hierarchy process to provide a more accurate safety conformity assessment, yielding reliable and informative results representing the vagueness of the bottling process decision-making process. This unique approach provides an opportunity for the production workers to work more collaboratively towards attaining new solutions to the uncertainty and imprecision problem in safety conformity for the bottling plant.
Emotion Detection Research: A Systematic Review Focuses on Data Type, Classifier Algorithm, and Experimental Methods
Authors: Destyanto Twin Yoshua R.
Published: August 2023

There is a lot of research being done on detecting human emotions. Emotion detection models are developed based on physiological data. With the development of low-cost wearable devices that measure human physiological data such as brain activity, heart rate, and skin conductivity, this research can be conducted in developing countries like Southeast Asia. However, as far as the author's research is concerned, a literature review has yet to be found on how this research on emotion detection was carried out in Southeast Asia. Therefore, this study aimed to conduct a systematic review of emotion detection research in Southeast Asia, focusing on the selection of physiological data, classification methods, and how the experiment was conducted according to the number of participants and duration. Using PRISMA guidelines, 22 SCOPUS-indexed journal articles and proceedings were reviewed. The review found that physiological data were dominated by brain activity data with the Muse Headband, followed by heart rate and skin conductivity collected with various wristbands, from around 5-31 participants, for 8 minutes to 7 weeks. Classification analysis applies machine learning, deep learning, and traditional statistics. The experiments were conducted primarily in sitting and standing positions, conditioned environments (for developing research), and unconditioned environments (applied research). This review concluded that future research opportunities exist regarding other data types, data labeling methods, and broader applications. These reviews will contribute to the enrichment of ideas and the development of emotion recognition research in Southeast Asian countries in the future.
Business Intelligence for Decision Support System for Replenishment Policy in Mining Industry
Authors: Seto Franklin Chandra Pragnyono , Daryanto Yosef , Diar Astanti Ririn
Published: August 2023

The mining industry has unique characteristics in the sense that usually, the plant is located in a remote area while the headquarters are located in an urban area. These conditions pose challenges for the industry related to coordination within companies. This coordination is very important, especially in relation to the decision-making that must be carried out by the company. One of the important managerial decisions is related to the replenishment policy. To make replenishment decisions, companies need past data, such as biodiesel consumption rate, and current data, such as current stock and storage capacity, where the source of those data is in the plant. Often, decisions must be taken quickly because they have impacts on the continuousness of production operations at the plant. However, the remote location and shipping routes across rivers have created new challenges in the flow of goods and services supply because the shipment depends on the tides of the river. This research proposes a business intelligence system that collects, sorts, and visualizes data, then analyzes the replenishment decision to support decision-making in the mining industry. The system uses Microsoft Power BI software which is integrated with the company’s ERP system. To illustrate the applicability of the proposed system, it is applied to a coal mining company, especially in relation to the replenishment policy of biofuel. The result of this study indicates that the proposed system can work. In addition, it can reduce decision-making time by 220.65%.

Authors: Bakun Oksana , Yuzko Oleksandr
Published: August 2023

The aim of our study was to examine the expression NLRP3-inﬂ ammasome and some indices in the blood of women with endometriosis- associated infertility using assisted reproductive technologies with included probiotic.Material and methods: For the purpose of the research we examined 30 infertile women. Control group consisted of 10 women with tubal infertility due to an inﬂ ammatory process in the anamnesis, in whom, as a result of a complex clinical and laboratory examination, no other diseases were detected and in terms of their health they could be equated with practically healthy women (age from 21 to 42 years, the average age was 29.75 years) and who did not take probiotic. The main group consists from 20 women with external genital endometriosis were included in assisted reproductive technologies. Patients from main group took probiotic 1 tablet twice a day with 10Ч109 Lactobacillus during 1 month in complex preparation (treatment) before assisted reproductive technologies. The indices of NLRP3-inﬂ ammasome determined before and after preparation. The study was performed in Bukovinian State Medical University and Centre of Reproductive Medicine. The primary infertility incidence was signiﬁ cantly higher in patients from main group. To analyze the expression of the NLPP3-inﬂ ammasome gene and determine the relative normalized expression of mRNA NLPP3-inﬂ ammasome, we used the polymerase chain reaction with reverse transcription in real time (RT-PCR). The object for molecular genetic studies by the RT-PCR method was the fraction of mononuclear cells isolated from the whole blood of patients with endometriosis. The value of p (authenticity diﬀ erence) was determined by Student’s table- Fischer. Diﬀ erences between contrasting averages were considered signiﬁ cant at p <0.05.Results and discussion: Analyzed the results of our research stated that in main group expression of NLRP3-inﬂ ammasome was 24.43, which is signiﬁ cantly higher than after preparation (0,70 accordingly). In control group expression of NLRP-3-inﬂ ammasome was 0.54.Expression of NLRP3-inﬂ ammasome increased in patients before preparation more than 34 times compare with patients after preparation accordingly.Conclusions. Consequently, after using probiotic, the increased level of NLRP3-inﬂ ammasome sharply decreases, indicating the eﬀ ectiveness and the possibility of use in the program for assisted reproductive technologies preparation.

In-depth basic data detection device based on Internet of Things technology
Authors: Xie Shanyi , Zhang Ziying , Cheng Chen , Wang Jian , Lian Chen
Published: August 2023

Due to the limited computing power of the perception layer of the Internet of Things (IoT), the ability to analyse and process the collected complex object information data is insufficient, and it is also difficult to complete the storage of a large amount of collected data. Through convolutional neural network-simple recurrent unit (CNN-SRU) deep learning, we preprocess a large amount of complex data in the perception layer. The data collected by the perception layer are first transmitted to the CNN for simple category screening and analysis, and then they reach the SRU link, which is updated and optimised again, to improve the integrity and accuracy of IoT information collection. The results show that the accuracy of gated recurrent unit (GRU), long–short-term memory (LSTM) and SRU algorithms shows a downward trend under the three error evaluation standards of root mean squared error (RMSE), mean absolute error (MAE) and relative error (RE), from 0.034 to 0.015, 0.028 to 0.012 and 0.024 to 0.013, respectively; in terms of training time. The SRU algorithm is increased by 54.52%; the maximum SRU in terms of data storage is increased to 33.22%; and the maximum SRU reduction in data mining energy consumption is 11.45%. This meets the requirements of IoT applications in big data mining.
Differences between journal and conference in computer science: a bibliometric view based on Bayesian network
Authors: Sun Mingyue , Yue Mingliang , Ma Tingcan
Published: August 2023

Purpose

This paper aims to investigate the differences between conference papers and journal papers in the field of computer science based on Bayesian network.

Design/methodology/approach

This paper investigated the differences between conference papers and journal papers in the field of computer science based on Bayesian network, a knowledge-representative framework that can model relationships among all variables in the network. We defined the variables required for Bayesian networks modeling, calculated the values of each variable based Aminer dataset (a literature data set in the field of computer science), learned the Bayesian network and derived some findings based on network inference.

Findings

The study found that conferences are more attractive to senior scholars, the academic impact of conference papers is slightly higher than journal papers, and it is uncertain whether conference papers are more innovative than journal papers.

Research limitations

The study was limited to the field of computer science and employed Aminer dataset as the sample. Further studies involving more diverse datasets and different fields could provide a more complete picture of the matter.

Practical implications

By demonstrating that Bayesian networks can effectively analyze issues in Scientometrics, the study offers valuable insights that may enhance researchers’ understanding of the differences between journal and conference in computer science.

Originality/value

Academic conferences play a crucial role in facilitating scholarly exchange and knowledge dissemination within the field of computer science. Several studies have been conducted to examine the distinctions between conference papers and journal papers in terms of various factors, such as authors, citations, h-index and others. Those studies were carried out from different (independent) perspectives, lacking a systematic examination of the connections and interactions between multiple perspectives. This paper supplements this deficiency based on Bayesian network modeling.
Editorial board publication strategy and acceptance rates in Turkish national journals
Authors: Tutuncu Lokman
Published: August 2023

Purpose

This study takes advantage of newly released journal metrics to investigate whether local journals with more qualified boards have lower acceptance rates, based on data from 219 Turkish national journals and 2,367 editorial board members.

Design/methodology/approach

This study argues that journal editors can signal their scholarly quality by publishing in reputable journals. Conversely, editors publishing inside articles in affiliated national journals would send negative signals. The research predicts that high (low) quality editorial boards will conduct more (less) selective evaluation and their journals will have lower (higher) acceptance rates. Based on the publication strategy of editors, four measures of board quality are defined: Number of board inside publications per editor (INSIDER), number of board Social Sciences Citation Index publications per editor (SSCI), inside-to-SSCI article ratio (ISRA), and board citation per editor (CITATION). Predictions are tested by correlation and regression analysis.

Findings

Low-quality board proxies (INSIDER, ISRA) are positively, and high-quality board proxies (SSCI, CITATION) are negatively associated with acceptance rates. Further, we find that receiving a larger number of submissions, greater women representation on boards, and Web of Science and Scopus (WOSS) coverage are associated with lower acceptance rates. Acceptance rates for journals range from 12% to 91%, with an average of 54% and a median of 53%. Law journals have significantly higher average acceptance rate (68%) than other journals, while WOSS journals have the lowest (43%). Findings indicate some of the highest acceptance rates in Social Sciences literature, including competitive Business and Economics journals that traditionally have low acceptance rates.

Limitations

Research relies on local context to define publication strategy of editors. Findings may not be generalizable to mainstream journals and core science countries where emphasis on research quality is stronger and editorial selection is based on scientific merit.

Practical implications

Results offer useful insights into editorial management of national journals and allow us to make sense of local editorial practices. The importance of scientific merit for selection to national journal editorial boards is particularly highlighted for sound editorial evaluation of submitted manuscripts.

Originality/value

This is the first attempt to document a significant relation between acceptance rates and editorial board publication behavior.
Cowboy epistemology: Rural school and district leadership for diversity and social justice
Authors: Holmes William T
Published: August 2023

This qualitative study focuses on the intersectionality of race and rurality by looking at the responses of Wyoming principals and superintendents to the issues of diversity and social justice within Wyoming. The responses are presented and analyzed through a new framework called Cowboy Epistemology, and the Cultural Competency Continuum (Lindsey et al., 2009). It appears that despite double-digit increases in diversity between 2010 and 2018, some Wyoming school and district administrators continue to demonstrate actions and practices congruent with the demographic divide, cultural homophily, and Whiteness along with cultural worldviews that suggest a failure to: (1) value diversity, (2) engage political organizations and individuals in a manner that advocates for the needs of diverse students, (3) implement multicultural instruction beyond superficial means, and (4) engage the community in tolerance for others who are different from the traditional White Wyoming ranching, conservative, materials extraction, isolationist way of life. While outliers and standards for social justice and diversity exist in Wyoming among and for administrators, more needs to be done to prepare and train administrators to engage in culturally proficient and sustaining instructional leadership so that administrators can serve all students, engage in community leadership, and resist the negative influences of Cowboy Epistemology, demographic divide, cultural homophily, and Whiteness. Chief among the more needs to be done for Wyoming administrators is the adoption of culturally responsive school and culturally sustaining instructional leadership practices and training on the culturally proficient continuum.
Annealing effect on the structural and optoelectronic properties of Cu-Cr-O thin films deposited by reactive magnetron sputtering using a single CuCr target
Authors: Tsai Du-Cheng , Chen Erh-Chiang , Huang Yen-Lin , Shieu Fuh-Sheng , Chang Zue-Chin
Published: August 2023

The aim of this study is to explore the structural and optoelectronic properties of Cu-Cr-O thin films when processed by the magnetron sputtering method using a single equimolar CuCr alloy target. These films were then post-annealed in a controlled Ar atmosphere at 500°C to 800°C for 2 h. The as-deposited Cu-Cr-O thin film consisted of an amorphous phase and exhibited extremely poor optoelectronic properties. After annealing was conducted at 500°C, monoclinic CuO and spinel CuCr2O4 phases were simultaneously formed in the film. Upon increasing the annealing temperature to 600°C, the CuCr2O4 phase reacted completely with the CuO phase and transformed into the delafossite CuCrO2 phase, possessing optimal optoelectronic performance. It has an electrical resistivity of 41 Ω-cm and a light transmittance of 49.5%, making it suitable for p-type transparent conducting electrodes. A further increase in annealing temperature resulted in larger grains and greater surface roughness and void density, which, in turn, degraded the optoelectronic performance.
Systematic Review of Environmental and Psychosocial Risk Factors associated with Attention Deficit Hyperactivity Disorder, Oppositional Defiant Disorder, and Conduct Disorder in Children and Adolescents
Authors: Elbagir Rasha , Faisal Mohd , O’Hanharan Susan
Published: August 2023

Background

In the majority of cases, attention deficit hyperactivity disorder (ADHD) is accompanied by one or more comorbid disorders, with the oppositional defiant disorder (ODD) being one of the most frequently diagnosed comorbid disorders. There is a lack of systematic reviews addressing the evidence for an association between the independent environmental and psychosocial risk factors associated with ADHD, ODD, and Conduct Disorder (CD).

Objective

This study aims to determine the link between ADHD and ODD/CD, specifically in terms of the most up-to-date environmental and psychosocial risk factors in the development of these illnesses.

Results

Eleven studies were included in this systematic review. Among these, ten studies involved environmental risk factors, and only one involved socioeconomic risk factors as exposure. Of the ten studies highlighting the environmental risk factors, six studies reported perinatal risk factors, three reported Atopic diseases as exposure measures, and one involved exposure to energy and coffee drinks. We have found that the most common risk factors associated with ADHD, ODD and CD in Europe and North America were Perinatal risk factors. In contrast, the risk factors of Atopic diseases were more common in Asia.

Conclusions

Most of the studies included in our systematic review fall within the scope of environmental risk factors were perinatal risk factors and atopic diseases are the most common risk factors. However, only one article highlighted the association of socioeconomic risk factors as an exposure. Our review results suggest the need for more research focused on psychosocial risk factors for ADHD and comorbid ODD/CD. Further research is required with the primary objective of investigating this association in greater depth and examining the possible mechanisms at varying levels is needed.
Control of iron stress in water-saturated tidal land using ameliorant and its impact on rice productivity
Authors: Wahyuni Lestari  , Ghulamahdi Munif , Purwono
Published: August 2023

Fe stress is a problem in swamp lands that reduces the growth and yield of rice. Providing various types of ameliorants and selecting rice varieties are considered an effort to obtain high rice productivity in tidal land. The research aimed to study the effect of various ameliorants on rice growth and production, and to obtain high productivity of tolerant variety to iron stress at different locations of tidal land. The research was conducted in Karya Bakti Village (1°10'34.8" S and 104°09’31.1” E), Rantau Rasau, East Tanjung Jabung, Jambi. This study adopted a split-plot design with different types and doses of ameliorant as the main plots and several rice varieties as the subplots with three replications. The results showed that the application of ameliorant rice husk ash, coconut husk ash, empty bunch oil palm compost, and goat manure stimulated vegetative and generative growth. Meanwhile, the Inpari 16 Pasundan variety was proven to have better growth and higher production as described through plant height, fresh weight of shoots and roots, dry weight of shoots and roots, root length, number of productive tillers, number of grains per panicle, 1,000 grain weight, and harvested dry grain. The highest rice production was in the Inpari 16 Pasundan variety, 9.3 tons ha-1 (low-Fe) and 7.6 tons ha-1 (high-Fe). The combination of rice husk ash (0.25 tons ha-1) + coconut husk ash (0.25 tons ha-1) + empty bunch oil palm compost (0.75 tons ha-1) + goat manure (0.75 tons ha-1) was the best combination to increase rice productivity. Inpari 16 Pasundan is considered a tolerant variety on tidal land with high-Fe stress. The interaction between ameliorants and varieties was significant on plant height at ages 2 and 4 weeks after planting at low-Fe, number of productive tillers at high-Fe, root length at low-Fe and high-Fe, 1,000-grain weight, and number of grains per panicle at low-Fe, and harvested dry grain at low-Fe and high-Fe.

Published: August 2023

This study reviews the search for the links between sustainable development and human security issues. It explains the integration of human security and sustainable development. It focuses on human security issues in Iraq including:  political security, social security, environmental security, economic security, food security, water security as well as terrorist threats. One of the most important requirements for achieving sustainable development is providing a safe and stable environment based on social justice, respect for human rights and guaranteeing a decent life for all people. The UN agenda 2030 comprises 17 sustainable development goals to achieve better and more sustainable future for humanity such as,  no poverty, zero hunger, quality education, good health and well-being, clean water and sanitation, gender equality, economic growth, clean energy industry, peace and justice. The study assumes that human security issues are considered major obstacles to achieving sustainable development in this country. Iraq cannot achieve sustainable development goals without ensuring human security and promoting human-centered development in order to guarantee stability, equality and the right of the next generations in life.
The Political Path of Copts in Egypt after 2011
Authors: Dr. Nasser kadhim Khalaf
Published: August 2023

The Coptic Church monopolized the religious and political representation of the Copts since the establishment of the Egyptian state. It withdrew from direct involvement in the political sphere during the presidency of Hosni Mubarak, characterized by a close relationship between the Church and the political regime, especially in times of perceived common threats. Consequently, the Church often supported the regime to safeguard against potential risks that might arise if the regime were to fall. In this context, Mubarak's regime used Islamist elements to intimidate the Copts, while justifying its actions by claiming that the secular political system had become sectarian. Consequently, Mubarak's regime closed its doors to Coptic representation within his party.

The January 25th, 2011 revolution provided an opportunity for the Copts to act more freely in the political climate. However, this newfound democracy had its challenges, as it witnessed the mobilization and substantial participation of Islamist groups, such as the Muslim Brotherhood, utilizing their organizational capacity. Through this religious polarization, the Islamists succeeded in winning elections, leading to the presidential victory of Mohamed Morsi.

The Muslim Brotherhood failed to alleviate the Copts' concerns about religious freedom and their marginalization in state institutions. Moreover, some Brotherhood leaders and their allies adopted a sectarian rhetoric against the Copts, which had negative consequences on the overall political direction of the Brotherhood. This ultimately led to their downfall, paving the way for a new era of governance in Egypt.

Thermal Control Investigations on Separation Zone of Ceramic Thermal Protection System
Authors: Huang Jie , Dai Zhen
Published: August 2023

Ceramic thermal protection system (TPS) is bonded to the skin of a hypersonic vehicle through a strain isolation pad, and the separation of the TPS will affect the safety of the vehicle. In this paper, the aeroheating of the separation zone for the ceramic TPS is studied and compared with that of the intact TPS. The intact TPS mainly considers the aeroheating of the gap. The heat flux increases sharply in both the gap and separation zone, especially on the windward wall. The difference of peak heat flux between the windward and leeward walls in the separation zone is much larger than that in the gap, and the heat flux away from the gap and separation zone gradually returns to the normal heat flux of the TPS. The heat flux in the gap only exists in the small zone of the upper part, whereas that in the separation zone is widely distributed on the side walls. The heat flux on the bottom of the gap approaches zero, whereas that of the separation zone is high in the middle and low at ends, and the heat flux in the middle reaches 55% of the normal heat flux of the TPS. In addition, an analysis of influencing factors is conducted.
Trajectory Analysis of the Hayabusa2 Capsule from a Single Airborne Observation
Authors: Zander Fabian , Buttsworth David R. , Birch Byrenn , Payne Allan
Published: August 2023

The reentry trajectory of the Hayabusa2 capsule has been measured using a single video stream captured during the Australian Airborne Observation of the Hayabusa2 capsule. A new analysis methodology was required, and developed, to enable the trajectory to be determined from a single viewpoint. The method developed used the star-field background visible in the video stream, combined with the aircraft Global Positioning System data, to establish lines of sight along which the capsule was measured in time. A set of common sense criteria including altitude and velocity limits were then used to exclude impossible trajectories. The remaining trajectories were then examined and evaluated using a least-squares fitting routine to analyze candidate ballistic trajectories. The trajectories were ranked based on the fit parameter, enabling the determination of the single most likely trajectory and a family of most probable trajectories. The most probable Hayabusa2 capsule trajectory inferred from the measurements passed 10 km west of Coober Pedy and traveled at a heading of 150 deg. Evaluation of other highly probable trajectories showed they all passed Coober Pedy at a similar distance; however, they tended toward a slightly higher heading, approaching 155 deg. The distance between the measurement aircraft and the capsule remained relatively constant at approximately 180 km throughout the measurement period. This work demonstrates a new method for determining the trajectory of an object measured with a star-field background. Importantly, we have used this to establish the Hayabusa2 reentry capsule trajectory, and hence the distance from our aircraft, which will allow the detailed analysis of our spectral data.

Two-Way Blade Modeling Method for Structural Redesign of Compressor Blades
Authors: Kojtych Solène , Audet Charles , Batailly Alain
Published: August 2023

Over the past few years, stringent environmental requirements and the need for increased overall efficiency have forced designers to bring turbomachine components closer to their operating limits. To address lifespan issues, costly redesign operations are thus unavoidable. These operations face many roadblocks, especially when they are triggered by nonlinear phenomena for which there exists no design guidelines. For aircraft engine blades, the handling of nonlinear structural interactions is a major challenge. This works proposes a proof of concept for the redesign of compressor blades undergoing structural contact interactions at the blade-tip/casing interface. The redesign process involves the modeling of an existing input blade, followed by a shape update based on an iterative optimization algorithm. A two-way modeling method is proposed to parameterize the input blade and generate a computer-aided design model from blade parameters describing several conical blade sections. The fidelity of the parameterized blade with respect to the input blade is assessed for the NASA blades rotor 37 and rotor 67. A high fidelity is observed with respect to geometric and dynamic characteristics. The modeling method is fully compatible with an iterative redesign process: it is applied to the redesign of rotor 37 to increase its robustness to contact interactions.

In this paper, we deal with both the static and dynamic behavior of uniform beams with uncertain boundary conditions. Uncertainty in spring constants is modeled as intervals, with specified lower and upper bounds. It is demonstrated that the classical interval analysis may lead to overestimation in the natural frequencies. A method is suggested to overcome the overestimation and obtain sharp bounds.
Deep Learning Closure of the Navier–Stokes Equations for Transition-Continuum Flows

The predictive accuracy of the Navier–Stokes equations is known to degrade at the limits of the continuum assumption, thereby necessitating expensive and approximate solutions to the Boltzmann equation. While tractable in one spatial dimension, their high dimensionality increases the computational challenge of multidimensional, multiphysical Boltzmann calculations. It is therefore desirable to augment the Navier–Stokes equations for accuracy under these conditions. We present an application of a deep learning method to extend the validity of the Navier–Stokes equations to transition-continuum flows. The technique encodes the missing physics via a neural network, which is trained to reduce the error between the Navier–Stokes and Boltzmann solutions. While standard DL methods can be considered ad hoc due to the absence of underlying physical laws, at least in the sense that the systems are not governed by known partial differential equations, the DL framework leverages the a priori known Boltzmann physics while ensuring that the trained model is consistent with the Navier–Stokes equations. The online training procedure solves adjoint equations, constructed using algorithmic differentiation, which efficiently provide the gradient of the loss function with respect to the learnable parameters. The model is trained and applied to predict stationary, one-dimensional shock thickness in low-pressure argon.

With the rapid development of vacuum tube transport technology, there is increased interest in understanding the behavior of the heat transfer of rarefied gas in a vacuum tube. Currently, most empirical correlations of forced convection heat transfer are conducted at the standard atmospheric pressure, so many correlations are not applicable to conditions below the atmospheric pressure. To investigate the heat transfer property under low-pressure conditions, the forced convection between isothermal plate and air in a low-pressure environment is numerically simulated. The results show that the traditional correlation of the forced convection heat transfer between the isothermal plate and gases is different from the actual results at low pressure, and the correlation is completely invalid when the pressure is lower than 0.2 kPa. Based on the data of numerical calculation, a modified correlation of forced convection heat transfer between an isothermal plate and gases under low pressure is proposed. The correlation coefficient [Formula: see text] is greater than 0.99, and the fitting error is less than 10% at the 95% confidence level. The change of heat transfer depends on the Reynolds number in the pressure range of 0.2–100 kPa, but the effect of Reynolds number is weakened and the effect of pressure is strengthened when the pressure is below 0.2 kPa.
What’s in a Name? Introducing Movement Science Media: The JOSPT Community’s Guide to Quality Musculoskeletal Rehabilitation Content
Authors: Bennett Rob , Ardern Clare L.
Published: August 2023

SYNOPSIS: The Journal of Orthopaedic & Sports Physical Therapy was first published in the summer of 1979 by the Orthopaedic and Sports Sections of the American Physical Therapy Association. The journal’s mission was to publish scientifically rigorous content and promote its application to movement-related health. In 1979, we were focused solely on 1 journal, and the publishing organization shared the journal’s name. In the decades since, our organization has grown such that it now publishes 3 peer-reviewed journals and provides plenty of additional resources to help the musculoskeletal rehabilitation community translate quality research to quality practice. We are pleased to reintroduce ourselves as Movement Science Media. We aspire to deliver your one-stop shop for trustworthy content—helping you stay informed about the latest in musculoskeletal rehabilitation.

Sivil Toplum Kuruluşlarının Afet Yönetimindeki Rolü: 6 Şubat Depremi Hatay Örneği
Authors: DURUEL Mehmet
Published: August 2023

İnsan hayatının kaçınılmaz gerçeklerinden birisi de afetlerdir. Depremler de doğal afetler içerisinde yıkıcı etkisi en yüksek olan hadiselerin başında gelmektedir. Yol açtığı can kayıplarının yanı sıra maddi ve manevi hasarların telafisi son derece güçtür. Öngörülemez olması, risk azaltma ve toplumsal bilinç geliştirme ile dirençli kent inşasının geniş zaman ve yüksek maliyetler gerektirmesi depreme karşı önlem almayı önemli ölçüde zorlaştırmaktadır. Diğer yandan deprem hadisesinin yaşanması durumunda aramak kurtarma faaliyetleri, acil sağlık hizmetleri, barınma, beslenme, ısınma ve giyim ile enkaz kaldırma faaliyetleri çok hızlı ve kapsamlı müdahaleyi zorunlu kılmaktadır. Özellikle altın saatler olarak ifade edilen ilk 72 saat arama kurtarma faaliyetleri bakımından hayati öneme sahiptir. On bir ili, yüzbinlerce binayı, milyonlarca insanı doğrudan etkileyen 6 Şubat depremlerinde acil müdahale için devlet imkânlarının yetersiz kaldığı bir gerçektir. Ancak şunu da kabul etmek gerekir ki böylesi devasa bir felaket karşısında dünyada hiçbir devletin zamanında acil müdahalede bulunmasının imkânsızlığı da bir başka gerçektir. Bu nedenle kamu kaynaklarının yanı sıra ulusal ve uluslararası kurum ve Sivil Toplum Kuruluşları ile gönüllülerin de desteğine ihtiyaç duyulmuştur. Nitekim depremin ilk gününden itibaren sivil toplum kuruluşları bölgeye hareket etmiş ve kendi faaliyet alanları ile ilgili depremzedeler destek olmaya çalışmışlardır. Bu çalışmada Hatay bölgesinde 6 Şubat 2023 tarihinde meydana gelen depremde Sivil Toplum Kuruluşlarının faaliyetleri ve depremden zarar gören bölge insanları için geliştirdikleri politika ve çözümlerler değerlendirilmiştir. Değerlendirme vaka analizine dayandırılmıştır. Bu kapsamda nitel araştırma tekniklerinden mülakat yöntemi tercih edilmiştir. Bu yöntem ile sahadan doğrudan alınan bilgiler sistematik bir şekilde sınıflandırılmakta, doğruluk ve güvenilirliği test edildikten sonra işlenmektedir. Çalışmada deprem öncesi, deprem sırası ve deprem sonrası süreçler olmak üzere üç aşama değerlendirilmeye alınmış ve tüm bu aşamalarda Sivil toplum kuruluşlarının deprem bölgesi olan Hatay’daki faaliyetleri, destek, deneyim ve öngörüleri tüm yönleriyle ele alınmıştır.
Expansion of Bond Dissociation Prediction with Machine Learning to Medicinally and Environmentally Relevant Chemical Space

Bond dissociation energetics underpin the thermodynamics of chemical transformations where bonds are broken or formed and can also be used to predict reaction rates and selectivities. Current machine learning (ML) models to predict bond dissociation energy (BDE) are largely limited in their elemental coverage to hydrogen and the second-row elements. This has restricted the applicability of ML-derived BDE predictions, particularly for molecules of medicinal relevance, since the heteroatoms S, Cl, F, P, Br, and I are commonly found in approved pharmaceuticals. Atmospherically and environmentally relevant molecules containing multiple halogen atoms have been similarly inaccessible. In this study, we considerably expand the size, elemental composition, and bond types of an extensive BDE database and train a new ML BDE model that includes C, H, N, O, S, Cl, F, P, Br, and I. We curate a new quantum chemical dataset of 531,244 unique zero-point energy inclusive homolytic dissociations of organic compounds. We investigate accuracy for out-of-sample molecules and implement iterative training and testing cycles during model development to improve the model accuracy. Improvements in predictive accuracy were achieved for datasets of pharmaceutically relevant molecules containing multiple C(sp2)–halogen bonds from 5.7 to 0.8 kcal mol-1 and polyhaloalkyl compounds with multiple C(sp3)–halogen bonds from 2.7 to 1.2 kcal mol-1 through the targeted augmentation of training data by as little as eight additional molecules. Our updated and expanded model (ALFABET) achieves a mean absolute error of 0.6 kcal mol-1 for both enthalpies and free energies compared to the quantum chemical ground truth. The graph-based representations utilized here outperform traditional cheminformatics features such as radial fingerprints, and there is no discernible improvement in accuracy by including more expensive QM-derived parameters, such as optimized bond lengths. Finally, we illustrate high accuracy in external prediction tasks for large halogenated natural products, pharmaceutically-relevant halogenated molecules, atmospherically-important halocarbons, and polyfluoroalkyl substances related to environmental toxicity.
