Parallel Force Feedback Device Design With Constant Jacobian Matrix and Net Weight Fully Balanced

Abstract Force feedback devices offer realistic and intuitive feedback to operators, and achieving higher accuracy and transparency has been a prominent research focus in this field. However, errors in real-time force or position calculations are inevitable, which can have adverse effects on the accuracy of the equipment. This article presents the design of a parallel mechanism that incorporates a constant force and velocity mapping relationship based on the type synthesis of the constant Jacobian matrix. Specifically, the mechanism maintains a fixed direction of force applied to the operating platform by the drive pair, which is mounted on the fixed platform in each limb, irrespective of position changes. This unique feature enables the mechanism to achieve a complete net weight balance. The implementation method is detailed in this article, which involves adding appropriate counterweights to achieve a balance between the weight of the connecting rod and the overall gravity of the operating platform. Furthermore, the optimization of structural parameters helps to improve the performance of the developed prototype. The proposed design scheme not only addresses the fundamental reduction of errors caused by real-time force and position mapping solving but also enhances operational transparency. Finally, simulation and experimental tests are conducted to validate the proposed theory.

Relationship of Body Composition and PMS Symptoms: A Systematic Review

Aims: Recent studies show that body composition is one of the most important factors in the menstrual cycle. The purpose of this study is to investigate more comprehensively the effect of body composition and anthropometric indicators on the symptoms of premenstrual syndrome (PMS). Materials and Methods: This study is a secondary study that is considered a systematic review according to the implementation method. The statistical population is all the studies that have dealt with the issue of the effect of anthropometric indicators on PMS from different aspects. Results: The final synthesis was performed on 7 articles after screening the studies. The synthesis of articles related to the relationship between anthropometric indicators on PMS showed that 47.8% of women in the world have PMS, with the highest prevalence being reported in Iran at 98%. Studies have shown that the incidence of PMS, increased appetite, and weight gain in women with a BMI greater than 25 kg / m2 is more common. Weight gain causes endocrine disorders that lead secretion of more sex hormones in obese or overweight women, which in turn leads to the symptoms of PMS. Studies have shown a direct and significant relationship between PMS symptoms waist circumference (WC), waist-to-height ratio (WTHR), and waist-to-hip ratio (WHR), which according to the results, more central fat mass in women causes more severe symptoms of this syndrome. Also, studies showed that the risk of depression and anxiety in women with PMS with a higher BMI and body fat mass is higher. Conclusion: Weight control and improvement of eating habits, can be effective in reducing the incidence of PMS symptoms. Furthermore, the high prevalence of PMS in studies requires further investigation and principled interventions with regard to physical and mental factors in this period.

Penerapan Inovasi Teknologi dalam Meningkatkan Hasil Tangkapan Ikan bagi Nelayan di KUB Bugel

Service activities were conducted in the Bugel Peni II and III Joint Business Group (KUB) in Bugel Village, Kulonprogo Regency. Fishermen who join this group often do not get maximum catches because they face various obstacles, such as limited technology and unpredictable weather conditions. This community service aims to provide portable FAD innovations and determine the success of using portable FADs in fishermen's catches. Portable FADs are proposed for this service activity to provide a solution to minimize losses due to these obstacles. Portable FADs are an innovation that stimulates fish behavioral responses using sound waves with a specific frequency on an attractor, developing from the concept of conventional FADs. The implementation method begins with outreach to fishermen in the Bugel Peni II and III Joint Business Group (KUB) regarding the concept and benefits of portable FADs. Practical training was carried out on the installation and use of these tools and education regarding their positive impact on fish catches. In addition, data collection was carried out through direct observations in the field to understand fish responses to portable FADs. The positive impact of this service activity is that the application of portable FADs provides in-depth insight into the urgency of using technology to increase fish catches by fishermen. Apart from that, this service activity also provides important insight regarding the natural factors fishermen face in implementing portable FADs, such as weather uncertainty, increasingly scarce fish resources, and natural conditions, namely high waves, which are the main obstacles in achieving the expected results.

Cooperative Spacing Control of Vehicle Platoon via Relative Output Feedback Considering Analog Fading Networks

ABSTRACTThe influence of analog fading channels on platoon control performance is studied via relative output feedback. The main goal is to determine the existence of a distributed output feedback controller capable of achieving mean square stability (MSS) for the underlying vehicle platoon systems over analog fading channels. First, the conditions, closely associated with the statistical characteristics of fading channels, for achieving platoon MSS are derived for three cases: undirected information flow (UIF) topology with identical fading channels, balanced directed information flow (BDIF) topology with identical fading channels, and general information flow topology (IFT) with nonidentical fading channels, respectively. These conditions explicitly reveal how the statistical characteristics of fading channels and IFT jointly affect vehicular stability. Second, in order to mitigate the impact of fading channels on platoon MSS, some feasible dynamic observer‐based controllers by using the relative output feedback, are proposed for each one of the former two situations by solving the corresponding modified Riccati inequalities (MRIs); and in the last situation, by employing edge Laplacian to model the vehicle platoon dynamics, a sufficient condition based on the solution of an LMI, and a feasible state‐based controller based on the solution of an MRI, are provided. Finally, simulations are carried out to compare three distinct fading channels, namely the Nakagami channel, Rician channel, and Rayleigh channel. The outcomes substantiate the superior and effective performance of the implemented control methods in guaranteeing the platoon MSS.

Scalable solutions for global health: the SalivaDirect model

The COVID-19 pandemic caught the world unprepared. Large-scale testing efforts were urgently needed, and diagnostic strategies had to rapidly evolve in response to unprecedented worldwide demand. However, the rollout of diagnostic testing and screening for SARS-CoV-2 was often impeded by logistical challenges, including regulatory delays, workforce shortages, laboratory bottlenecks, and supply chain disruptions. Recognizing these hurdles early on, we developed a testing approach that supported frequent, repeat testing, particularly as communities reopened. We hypothesized and experimentally demonstrated that saliva was a suitable specimen for the detection of SARS-CoV-2. This finding was advanced into the development of open-source, extraction-free reverse transcription polymerase chain reaction protocols using readily available, “off-the-shelf” reagents and equipment for the direct detection of SARS-CoV-2 in saliva (“SalivaDirect’’). Working with the US Food and Drug Administration (FDA), we established a novel regulatory framework wherein the FDA granted Emergency Use Authorization to Yale University to offer the SalivaDirect test protocol to high-complexity diagnostic laboratories (as designated by the Clinical Laboratory Improvement Amendments) with quality oversight provided by Yale. This grew into a network of more than 200 labs across the United States that, as of May 2024, resulted in over 6.5 million SARS-CoV-2 tests. By making the protocol flexible and open-source, laboratories were able to rapidly and economically scale testing using a simple, self-collected saliva specimen. Additionally, fostering a national network of laboratories enabled real-time exchanges, problem solving, and the development of community best practices. Preparing for the next pandemic, or simply the next seasonal epidemic, the SalivaDirect model of deploying a readily available, expandable solution and accompanying network provides a proven method for the successful implementation of pathogen testing in the United States and globally.

Comparing the effects of oral sucrose and kangaroo mother care on selected physiological variables and pain resulting from venipuncture in premature newborns admitted to neonatal intensive care units

BackgroundPremature newborns admitted to neonatal intensive care units (NICUs) undergo numerous painful interventions during care and treatment. The purpose of this study was to compare the effects of using sucrose and kangaroo mother care by on selected physiological variables and pain resulting from venipuncture in premature infants admitted to NICUs affiliated with Shiraz University of Medical Sciences.MethodsThis clinical trial included premature infants admitted to 2 NICUs. The sample size consisted of 66 neonates, with 22 newborns in each group. Randomization was performed using the block allocation method. Data collection involved a demographic questionnaire, the neonatal infant pain scale, and a pulse oximetry device. Friedman, Kruskal–Wallis, and Dunn’s post hoc tests employed for data analysis, with a significance level of P < 0.05.ResultsThe use of oral sucrose and kangaroo care demonstrated significant differences in breathing rate, heart rate, and average arterial blood oxygen saturation during and after venipuncture (P < 0.05). Oral sucrose was found to be significantly more effective than kangaroo care. Neonates under kangaroo care exhibited more regular heart rates compared to the other group (P < 0.05). The utilization of oral sucrose and kangaroo care had varying effects on the average pain score resulting from venipuncture in premature neonates (P < 0.05).ConclusionsBoth methods proved effective in reducing pain and improving physiological variables.

Risk Analysis Of Musculoskeletal Disorders (MSDs) Of The Material Handling Process In Waste Processing Operators Using The Rapid Whole Body Assessment Method

: Businesses should never stop trying to include every employee in their operations and never skimp on safety precautions. One of the safety methods in the worker-centered approach implementation is the significance of ergonomics. Typically, material handling phases in production processes include physical labor that demands a lot of operator effort. Handling objects by hand raises the possibility of workplace mishaps, which can lead to musculoskeletal injuries. This study focuses on the different labor postures used for gathering, transferring, and positioning waste as well as the manual handling of waste items up to the shredding area. This study evaluates work postures that may result in symptoms of musculoskeletal diseases using the Rapid Entire Body Assessment (REBA) technique. There are three steps in this process. Prior to lowering the waste bucket to the designated place, gather the trash first, then hoist and carry it till it reaches the mechanical area. Three grades 9, 2, and 6 were obtained from the analysis utilizing the REBA (Rapid Entire Body Assessment) approach. Based on these findings, the first stage has to be improved right away. Thus, in order to meet the improvement objective, we created a telescopic reach that enables employees to change the height a device that aids in bettering workers' posture while picking up trash.

Evaluating OSPE as a Formative Assessment Tool for Medical Students

Introduction. Objective structured practical examination (OSPE) is a globally recognized and widely implemented assessment method used for evaluating students in practical examinations. It requires examinees to complete various tasks within a set time frame, each assessed against predetermined criteria designed to measure practical skills and attitudes. This study aimed to assess the effectiveness of the OSPE as a tool for internal assessment in the subject of Anatomy for first-year MBBS students, comparing its performance against the traditional practical examination (TPE) method. Methods. In this prospective study, an OSPE tool specific to Anatomy was developed and validated for face and content to ensure that the OSPE stations were standardized and well-constructed. The part-leaving test covered the Thorax and Brain chapters using both the TPE and OSPE methods. A Bland-Altman plot was employed to assess the agreement between the quantitative assessments of both methods. Additionally, a 5-point Likert scale was utilized to gauge the perceptions of both students and faculty members regarding the assessment methods. Results. The analysis revealed a significant difference between the scores obtained from OSPE and TPE. The intraclass correlation coefficients for reliability between TPE and OSPE were 0.81 for the Thorax chapter and 0.84 for the Brain chapter. Additionally, the Bland-Altman plots illustrating the scores from both assessment methods indicated low bias and no definite pattern. While no significant outliers were identified for the Brain part, the Thorax part exhibited outliers at a rate of 6.43%, suggesting the presence of low-impact erratic variables. The Chi-square test for student perceptions yielded significant results for the entire questionnaire. In contrast, faculty perceptions showed significant results for all questions except for two. Conclusions. Due to the high intraclass correlation coefficients between TPE and OSPE and the absence of bias, systematic errors, and erratic variables, OSPE is a promising assessment tool. Students perceived that OSPE decreased the chances of failure and that the questions asked in OSPE were more relevant compared to the traditional method. Faculty members also noted that OSPE provided reasonably high transparency and decreased subjective bias compared to TPE. Considering these factors, it can be concluded that OSPE is a viable potential tool to replace TSE.

Elucidating proper framework for determination of threading dislocation densities in semiconductor films: a comprehensive study based on Ge/Si(001)

Abstract Method of deducing threading dislocation densities (TDDs) from X-ray diffraction (XRD) peak widths has been reevaluated based on crystallography theories, and Ge/Si heteroepitaxial structures were taken as model materials for investigation. The procedure was tailored in accordance with the specific designs of modern XRD systems to minimize instrumental interference, while practical characteristics of heteroepitaxial films was also considered to avoid intrinsic errors. TDDs of samples grown with different epitaxy methods were investigated by using the newly implemented XRD method as well as etch pit density (EPD) method, and satisfactory agreement has been achieved among 3 independently calculated sets of TDD results: two from XRD and one from EPD. Those values were further corroborated by cross-sectional TEM analysis. Key considerations that are of scientific and technical importance in TDD studies were also discussed in detail. The current work has provided not only the most up-to-date elucidation on obtaining TDD values in semiconductor epitaxial films, but also insight into the long-existing ambiguity in TDD calculation methods, which will be helpful for future studies of defect density characterizations on various material systems.&amp;#xD;

Ultrasonic A-Scan Signals Data Augmentation Using Electromechanical System Modelling to Enhance Cataract Classification Methods

The use of artificial intelligence in diverse diagnosis areas has significantly increased in the past few years because of the advantages it represents in clinical routine. Among the diverse diagnostic techniques, the use of ultrasounds is often preferred because of their simplicity, low cost, non-invasiveness, and non-ionizing characteristic. However, obtaining an adequate number of patients and data for training and testing machine learning models is challenging. To overcome this limitation, a novel approach is proposed for simulating data produced by ultrasonic diagnostic devices. The implemented method was based on a clinical prototype for eye cataract diagnosis, although the method can be extended to other applications as well. The proposed model encompasses the electric-to-acoustic signal conversion in the ultrasonic transducer, the wave propagation through the biological medium, and the subsequent acoustic-to-electric signal conversion in the transducer. Electrical modelling of the transducer was performed using a two-port network approach, while the acoustic wave propagation was modelled by using the k-Wave MATLAB toolbox. It was verified that the holistic modelling approach enabled the generation of synthetic data augmentation, presenting high similarity with real data.

Bridging length and time scales in predictive simulations of thermo-mechanical processes

Abstract This work introduces a theoretical formulation and develops numerical methods for finite element implementation of the formulation so as to extend the Concurrent Atomistic-Continuum (CAC) method for modeling and simulation of finite-temperature materials processes. With significantly reduced degrees of freedom, the CAC simulations are shown to reproduce the results of atomically resolved molecular dynamics simulations for phonon density of states, velocity distributions, equilibrium temperature field of the underlying atomistic model, and also the density, type, and structure of dislocations formed during the kinetic processes of heteroepitaxy. This work also demonstrates the need of a mesoscale tool for simulations of heteroepitaxy, as well as the unique advantage of the CAC method in simulation of the defect formation processes during heteroepitaxy.

Penetration rates of behavioral health consultants targeting cardiovascular disease and associated modifiable risk factors among military health care beneficiaries.

Targeting cardiovascular disease (CVD) and its associated risk factors is important not only in the general population, but also among those served by the military health care system. The primary care behavioral health model of integrating behavioral health consultants (BHCs) into a primary care setting is one method for enhancing how these modifiable risk factors are addressed; however, it is unknown how often BHCs are used to target those with biopsychosocial factors contributing to CVD and those with diagnosed CVD. The present study evaluated what percentage of primary care patients with diagnosed CVD risk factors (i.e., tobacco use, obesity, and depression) or diagnosed CVD were referred to BHCs. Data were drawn from electronic health records of U.S. military primary care clinics over the 3-year period from January 2017 to December 2019. A total of 1,321,072 unique individuals were included. Among the sample, 37.1% were active duty, 40.6% were married, 43.8% were female, and 30.9% were between 45 and 64 years old. The study revealed penetration rates of 1.5% (8,577 of 583,659 patients) for patients diagnosed with CVD, 5.3% (10,286 of 192,566 patients) of those demonstrating tobacco use, 3.4% (8,765 of 256,852 patients) of those demonstrating obesity, and 20.0% (31,125 of 155,656 patients) of those diagnosed with depression. These findings suggest that BHCs are underutilized for targeting CVD and some associated risk factors in military primary care clinics. Research should explore whether these findings replicate in other health care systems and implement methods to improve BHC utilization. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

AI-Enabled Multi-Mode Electronic Information Innovation Practice Teaching Reform Prediction and Exploration in Application-Oriented Universities

In view of professional learning and practical training in traditional electronic information education of application-oriented universities, this paper constructs electronic information–innovation practice teaching reform (EI-IPTR).In this scheme, by an integrating artificial intelligence (AI)-enabled curriculum with a multi-mode integrated platform and open-style module, big data-based comprehensive education resources are optimally configured.

Thus, it accurately evaluates them for teachers to efficiently manage their teaching process in accordance with their aptitude. The teaching reform practice verifies that the AI-enabled big data optimization of teaching reform has a better effect by the above multi-mode innovation. It exhibits an obvious improvement in the quantity and quality of students’ professional knowledge, personal ability, teamwork, and innovative practice. It is also in accordance with the independent completion of practical course teaching in the analysis of big education data. In addition, it realizes high-quality practical teaching by combining multi-mode, multi-level, and open discipline foundations together with efficient, professional skills.

Single Cell VDJ Sequencing of Normal and Malignant B and T Cells.

Recent developments in single cell sequencing technologies enable researchers to examine heterogeneity of cell types and subclusters even deeper. First assays were only available for transcriptome analysis of up to 10,000 cells, but nowadays up to 60,000 cells or even more can be analyzed. Whereas initially only analysis of mRNA expression was possible, currently single cell methods multiplied, with extension of assays for examination of surface molecule expression, DNA accessibility (ATAC-seq), antigen specificity, and B or T cell receptor repertoires. Also, spatial transcriptomics or CRISPR screenings, augmenting classical CRISPR/Cas9 screens by combining them with transcriptomic data at single cell level, can be evaluated. The composition of B and T cell clones-of malignant cells in lymphomas and leukemia, as well as of infiltrating B or T cell clones in other types of cancer-is especially important in tumor research, as these clones may give valuable hints for tumor development and control. This chapter presents detailed methods for implementation and analysis of single cell B and/or T cell receptor repertoire sequencing on the Chromium system from 10× Genomics and the Rhapsody™ system from BD Bioscience.

Is implementation science a science? Not yet.

Getting the science right for implementation is critical for making the processes for improving outcomes more predictable and effective in global public health. Unfortunately, "implementation science" has become a catchphrase for ideas, assumptions, and findings concerning the science to service gap and how to close it. The purpose of this paper is to explore the dimensions of a "science of implementation" that meets the definitions of a science and is focused on implementation variables (i.e., purposeful processes to put innovations into effect so that intended benefits can be realized). A science of implementation is important for accomplishing the goals related to improving the health and well-being of populations around the world. Much of public health involves interaction-based interventions. In a typology of science, interaction-based interventions are created by specifying the nature of certain exchanges between and among individual people or groups. The complexity of developing interaction-based independent variables requires meeting benchmarks for fidelity to assure the presence and strength of implementation independent variables. The paper presents information related to the following tenets: (1) A science of implementation is based on if-then predictions. Science is cumulative. As predictions are made, tested, and elaborated, the facts accumulate to form the knowledge base for science and practice. (2) Implementation variables are interaction-based inventions and, therefore, must be created and established so the specific set of activities related to implementation can be studied. (3) A science of implementation is based on theory that organizes facts, leads to testable predictions, and is modified or discarded based on outcomes. (4) A science of interaction-based implementation depends on frequent measures of independent and dependent variables specific to implementation methods and outcomes. Two examples illustrate the implications for theory, research, and practice. The paper advocates a paradigm shift to a new mental model that values fidelity over tailoring, has one size fits all as a goal, and is concerned with the function of evidence rather than the form of evidence based on RCTs. Global health fundamentally requires scaling implementation capacity so that effective innovations can be used as intended and with good effect to achieve population benefits.
