Published: May 2022

In this paper, the hydrodynamic modeling and parameter identification of the RobDact, a bionic underwater vehicle inspired by Dactylopteridae, are carried out based on computational fluid dynamics (CFD) and force measurement experiment. Firstly, the paper briefly describes the RobDact, then establishes the kinematics model and rigid body dynamics model of the RobDact according to the hydrodynamic force and moment equations. Through CFD simulations, the hydrodynamic force of the RobDact at different speeds is obtained, and then, the hydrodynamic model parameters are identified. Furthermore, the measurement platform is developed to obtain the relationship between the thrust generated by the RobDact and the input fluctuation parameters. Finally, by combining the rigid body dynamics model and the fin thrust mapping model, the hydrodynamic model of the RobDact at different motion states is constructed.

Radiofrequency (RF) catheter ablation has emerged as an effective alternative for the treatment of atrial fibrillation (AF), but ablation lesions will result in swelling and hematoma of local surrounding tissue, triggering inflammatory cell infiltration and increased release of inflammatory cytokines. Some studies have shown that the inflammatory response may be related to the early occurrence of AF. The most direct way to inhibit perioperative inflammation is to use anti-inflammatory drugs such as glucocorticoids. Here, we prepared polylactic-co-glycolic acid (PLGA) nanoparticles loaded with budesonide (BUD) and delivered them through irrigation of saline during the onset of ablation. Local high temperature promoted local rupture of PLGA nanoparticles, releasing BUD, and produced a timely and effective local myocardial anti-inflammatory effect, resulting in the reduction of acute hematoma and inflammatory cell infiltration and the enhancement of ablation effect. Nanoparticles would also infiltrate into the local myocardium and gradually release BUD ingredients to produce a continuous anti-inflammatory effect in the next few days. This resulted in a decrease in the level of inflammatory cytokine IL-6 and an increase of anti-inflammatory cytokine IL-10. This study explored an extraordinary drug delivery strategy to reduce ablation-related inflammation, which may prevent early recurrence of AF.

Published: May 2022

Research Question: What is the current status of self-efficacy beliefs towards research and research utilization (RU) of University of Santo Tomas Faculty of Medicine and Surgery (UST-FMS) graduates who had Clinical Epidemiology in their basic medical education curriculum? Significance of the Study: There is an increase in research and RU trends globally as adherence to practice based on evidence results in improved patient outcomes. Limited studies are available in describing research and RU of Filipino physicians and there is no study available specific for UST-FMS graduates. Objectives: The study aims to describe self-efficacy beliefs towards research and RU of UST-FMS graduates’ batches 2012-2016 who had Clinical Epidemiology in their basic medical education. Study Design: A single-center, quantitative descriptive survey design was used. Methodology: Participants were graduates of UST-FMS batches 2012-2016, currently working at the University of Santo Tomas Hospital. Evidence-based Practice Confidence Scale (EPIC scale) and Edmonton Research Orientation Survey (EROS) were used to assess the research and RU of the participants gathered through snowball sampling. Statistical Analysis: Descriptive statistics such as means and standard deviations were used to analyze the EPIC and EROS scores. Results: The UST-FMS graduates value research and are generally confident in their ability to participate in evidence-based medicine. However, they rarely conduct research and have a low understanding of statistics. Conclusion: The self-efficacy beliefs of UST-FMS graduates towards research and RU may be attributed to several factors. Clinical epidemiology as a subject may be improved by adding more lectures on statistics while hospitals should create avenues to support the conduct of research.

Introduction: The bacille Calmette-Guerin (BCG) vaccine is used for the prevention of tuberculosis (TB) worldwide. Evidence reports a much lower incidence of COVID-19 in TB-endemic areas implying a possible protective mechanism of BCG in countries with mandated BCG policies. The objective of the study is to synthesize and critically evaluate the effectiveness of national BCG vaccination policies in reducing infection and severity of COVID-19 in their native population. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a comprehensive search using pre-identified keywords will be done in PubMed, Cochrane, HERDIN Plus, WPRIM, Web of Science and EBSCO databases. After the initial selection of studies based on eligibility criteria, methodological appraisal will be conducted using the Joanna Briggs Institute appraisal instruments and an adapted quality assessment checklist for ecologic studies. Relevant data will be extracted and synthesized including reporting descriptive and inferential statistics to interpret results. Results: The study will generate a systematic review synthesizing evidence regarding the effects of BCG in curtailing the spread of the COVID-19 pandemic. Discussion: The battle against the COVID-19 pandemic is far from over, and as such, further studies must be undertaken to verify the evidence behind initial strategies in battling it. This includes the use of BCG in decreasing COVID-19 incidence and mortality. The results of the review can ultimately guide health authorities and policy makers create evidence-based decisions regarding BCG vaccination policies and clinical trials related to COVID-19 control and prevention.

Telemedicine has been an emerging method for delivering healthcare services due to the challenges brought by the COVID-19 pandemic. This descriptive quantitative correlational study is aimed at assessing the knowledge, attitudes and perceptions (KAP), and their relationship among adults aged 18-34 without prior experience in the use of telemedicine in Manila, Philippines during the COVID-19 pandemic. The study had 322 eligible respondents who answered an online survey questionnaire of three parts that asked for their socio-demographic profile, KAP on telemedicine. Descriptive statistics, profile analysis and Spearman’s rho were utilized as statistical tools. The respondents’ knowledge was on an average to low level, and attitude and perception towards telemedicine were both neutral. Results showed no significant difference between the KAP of the respondents when analyzed according to socio-demographic variables. Knowledge and attitude have a weak positive linear relationship while knowledge and perception have a moderate positive linear relationship. A strong positive linear relationship was indicated between attitude and perception. A positive attitude can be attributed to a positive perception towards telemedicine but both do not consequently come from high knowledge levels of it.

INTELECTO GERAL
Authors: Marques Rodrigo Moreno
Published: May 2022

No trecho dos Grundrisse, conhecido como Fragmento sobre as máquinas, Marx discute o papel do conhecimento coletivo, que ele chama de intelecto geral, em processos de produção da grande indústria, onde a automação industrial tende a expulsar do processo de trabalho o único agente capaz de criar valor: o trabalhador. Nesse exercício de reflexão, Marx imagina que essa contradição poderia abalar as bases do modo de produção capitalista e abrir uma janela para sua superação. O intelecto geral de Marx é o ponto de partida do artigo, que tem como objetivos: (i) analisar a controversa hipótese acerca do intelecto geral que Marx registra nos Grundrisse; (ii) apresentar a origem da expressão intelecto geral, que data do começo do século XIX, décadas antes do seu registro nesse manuscrito; e (iii) revelar como Marx supera aquela interpretação alguns anos depois, ao expor suas conclusões sobre o papel da ciência e da técnica nos processos de produção capitalistas. Este artigo estabelece uma interlocução com algumas reflexões de Matteo Pasquinelli e Michael Heinrich, entre outros autores, em confronto com os escritos que Marx nos legou.

Published: May 2022

Purpose Respiratory motion during positron emission tomography (PET) scans can be a major detriment to image quality in oncological imaging, leading to loss of quantification accuracy and false negative findings. The impact of motion on lesion quantification and detectability can be assessed using anthropomorphic phantoms with realistic anatomy representation and motion modelling. In this work we design and build such a phantom, with careful consideration of system requirements and detailed force analysis.

Methods: We start from a previously-developed anatomically-accurate shell of a human torso and add elastic lungs with a highly controllable actuation mechanism which replicates the physics of breathing. The space outside the lungs is filled with a radioactive water solution. To maintain anatomical accuracy in the torso and realistic gamma ray attenuation, all motion mechanisms and actuators are positioned outside of the phantom compartment. The actuation mechanism can produce a plethora of custom respiratory waveforms with breathing rates up to 25 breaths per minute and tidal volumes up to 1200mL.

Results: Several tests were performed to validate the performance of the phantom assembly, in which the phantom was filled with water and given respiratory waveforms to execute. All parts demonstrated nominal performance. Force requirements were not exceeded and no leaks were detected, although continued use of the phantom is required to evaluate wear. The respiratory motion was determined to be within a reasonable realistic range.

Conclusions: The full mechanical design is described in this paper, as well as a software application with graphical user interface which was developed to plan and visualize respiratory patterns. Both are available open source and linked in this paper. The developed phantom will facilitate future work in evaluating the impact of respiratory motion on lesion quantification and detectability.
Overview of Fundamental Frequency Sensorless Algorithms for AC Motors: a Unified Perspective
Authors: Chen Jiahao , Yuan Xin , Blaabjerg Frede , Lee Christopher H. T.
Published: May 2022

This paper uses active flux concept to review fundamental frequency sensorless algorithms for both induction and permanent magnet motors in one framework. Fundamentally, sensorless torque estimation can be directly solved using voltage model (VM) estimator, or indirectly solved using current model (CM) estimator. The latter turns the torque estimation problem into a speed estimation problem. The stator flux in VM and the d-axis angle in CM are deemed as the two sets of original states for sensorless drive. Through change of states, the direct torque estimation can be realized via observer designs; whereas the speed dependency of the unknown state (e.g., active flux and emf) gives rise to a class of speed estimation methods, known as model reference adaptive system (MRAS). The idea of a general speed observer is proposed to summarize various separate speed estimation methods needed for direct torque estimation. It is suggested to adopt inherently sensorless designs such that two-way coupling between torque estimation and speed estimation is avoided. For induction motors, it turns out the unmodelled voltage in the active flux dynamics reveals current flowing in rotor bars and can be further modelled, for which the solutions to regeneration instability problem are discussed, and change of states is recommended to attain global stability. Finally discussed are the results of slow reversal test, where local weak observability of ac motors can be potentially preserved.
Risk Assessment of Post-Fault Temporary Overvoltage Using Generalized Short-Circuit Ratio
Authors: Xin Huanhai , liu xinyu , Zheng Di , Chen Dong , Zhou Yuhan , Marshall Benjamin
Published: May 2022

Temporary overvoltage (TOV) is becoming one challenge for the integration of significant power electronics resources into a power system. To adequately assess the risk of TOV in a Multi-Infeed Power Electronic System (MIPES), a comprehensive methodology is proposed in this paper. The paper starts with analyzing the mechanism of TOV, which reveals that TOV is dominated by excessive reactive power resulting from control lagging of converters. Then, the principle of estimating the level of TOV for a Voltage Source Converter (VSC) connecting to an infinite bus is introduced. After that, a methodology based on the concept of generalized short-circuit ratio for overvoltage (gSCR-TOV) is introduced to quantify the risk of TOV in a MIPES. To localize the weakest node, the weighted sensitivity matrix is proposed to pinpoint the bus subject to highest TOV in a MIPES. Finally, case studies of EMT time-domain simulations are carried out and verifies the effectiveness of the proposed methodologies.
An Area-variant Type MEMS Capacitive Sensor Based on A Novel Bionic Swallow Structure for High Sensitive Nano-indentation Measurement
Authors: Gao Wendi
Published: May 2022

 In this paper, a high sensitive area-variant type MEMS capacitive sensor was proposed for nano-indentation measurement. The proposed bionic swallow structure processed a high mechanical sensitivity without influences from the load coupling effect. Six comb arrays were optimized and integrated into the proposed sensor with a novel comb sensing configuration for eliminating electrostatic interferences resulting from multiple combs and maintaining compact chip size. Based on the proposed micro-machined process, comb arrays have been fabricated with great consistency, which exhibited a static differential output of 0.0554 pF. The fabricated sensor has been characterized with rigid glass cube and AFM cantilevers, and the measured force sensitivity can reach 98.54 aF/nN for a larger measurement range of 142 µN with a linearity of 0.9996. The fabricated sensor also exhibited a high resolution of 0.9819 nN, indicating its great feasibility in nano-indentation measurement at the sub-nano-Newton level.  
Beyond-Cell Communications via HAPS-RIS

Published: May 2022

 The ever-increasing number of users and new services in urban regions can lead terrestrial base stations (BSs) to become overloaded and, consequently, some users to go unserved. Compounding this, users in urban areas can face severe shadowing and blockages, which means that some users do not receive a desired quality of service (QoS). Motivated by the energy and cost benefits of reconfigurable intelligent surfaces (RIS) and the advantages of high altitude platform stations (HAPS), including their wide footprint and strong line-of-sight (LoS) links, we propose a solution to service the stranded users using the RISaided HAPS. More specifically, we propose to service the stranded users by a dedicated control station (CS) via a HAPS equipped with RIS (HAPS-RIS). Through this approach, users are not restricted from being serviced by the cell they belong to; hence, we refer to this approach as beyond-cell communication. As we demonstrate in this paper, beyond-cell communication works in tandem with legacy terrestrial networks to support uncovered or unserved users. Optimal transmit power and RIS unit assignment strategies for the users based on different network objectives are introduced. Numerical results demonstrate the benefits of the proposed beyond-cell communication approach. Moreover, the results provide insights into the different optimization objectives and their interplay with minimum quality-of-service (QoS) and network resources, such as transmit power and the number of reflectors. 
CPM Olympics: Development of Scenarios for Benchmarking in Networked and Autonomous Driving

Published: May 2022

The Cyber-Physical Mobility (CPM) Remote project provides web-based access to a simulation service and the CPM Lab itself, which is provided by the Chair of Embedded Software at RWTH Aachen University. With this approach, users no longer need special hardware, software, or physical access to use the simulation tool and the CPM Lab. This reduces the effort required to participate in research compared to the conventional simulation and lab setup. CPM Remote already offers uniform hardware by outsourcing the simulation to our Chair’s servers and uniform software through the computer simulation of the CPM Lab. This paper proposes extending the CPM Remote framework by a set of formalized problems and a unified evaluation method. These benchmarks detect whether the vehicles have successfully passed through the scenario and evaluate the quality of the driven trajectories. We compiled the extracted scenarios into an event, the CPM Olympics. Thus, CPM Remote now has a fully defined stack for the objective comparison of algorithms for networked and autonomous driving

Self-driving laboratories receive increasing acceptance as they are used in research and education. For research, they mainly serve as a platform on which algorithms can be tested under realistic conditions before getting deployed into the real world. In education, they can add value by creating a reference to reality as they o er an application for theoretical knowledge. In combination with the fact that practical work is well appreciated among students, such setup helps to motivate and thus enhance the learning experience. However, not every institution has the capabilities to create a self-driving lab on its own. Instead, open-source and remotely accessible laboratories, like our Cyber-Physical Mobility Lab (CPM Lab) can be used to engage with the domain of networked and autonomous vehicles. By means of two of our courses, we demonstrate the capabilities of the CPM Lab. These two courses can either be used as groundwork to develop own lectures in this domain, or used directly since the course materials are open-source.

The concept of structure engineering has been proposed for the exploration of the next generation of radiation detectors with improved performance. A Time Of Flight Positron Emission Tomography (TOF-PET) scanner with heterostructured scintillators with a pixel size of 3.0×3.1×15 mm3 was simulated. The heterostructures consisted of alternating layers of BGO as a dense material with high stopping power and plastic as a fast light emitter. Using the GATE simulation toolkit, a detector time resolution was calculated as a function of the deposited and shared energy in both materials on an event-by-event basis. We saw that while sensitivity was reduced to 32% for 100 µm thick plastic layers and 52% for 50 µm, the CTR distribution improved to 204±49 ps and 220±41 ps respectively, compared to 276±9 ps for bulk BGO. We divided the events into three groups based on their CTR and modeled them with different Gaussian TOF kernels. On a NEMA IQ phantom, the heterostructures had better contrast recovery in early iterations, while on the other hand, BGO achieved a better Contrast-to-Noise Ratio (CNR) after the 10th - 15th iteration due to the higher sensitivity. The developed simulation and reconstruction methods constitute new tools for evaluating different detector designs with complex time responses.

Published: May 2022

In this paper, we bring forward the use of the recently developed Signature Transform as a way to measure the similarity between image distributions and provide detailed acquaintance and extensive evaluations. We are the first to pioneer RMSE and MAE Signature, along with log-signature as an alternative to measure GAN convergence, a problem that has been extensively studied. We are also forerunners to introduce analytical measures based on statistics to study the goodness of fit of the GAN sample distribution that are both efficient and effective. Current GAN measures involve lots of computation normally done at the GPU and are very time consuming. In contrast, we diminish the computation time to the order of seconds and computation is done at the CPU achieving the same level of goodness. Lastly, a PCA adaptive t-SNE approach, which is novel in this context, is also proposed for data visualization.

This project work deals with the investigating and analysis of failure modes in 16A switch. The objective of this project is to increase the lifespan of the switches and to operate safer in high voltages. Mainly in water heater, due to fluctuation or over loading reasons, heat is produced in the switch terminals, and this causes the failure effects in electric switch components. Therefore, to avoid or reduce the switch internal components failure, this work is carried out. Different approaches are initiated to measure the switch failure reduction effects, such as, analyzing the effects by cooling paint coating used to decrease the heat effect and measuring the temperature reduction value. From the inference of the results, the suggestions to avoid the effects of 16 A switch damages have been provided.

ABSTRACT

Background: Diabetic Peripheral Neuropathy (DPN) is one of the type 2 Diabetes Melitus (T2DM) complication, which may lead to diabetic foot ulcer and lower extremity amputation. Inflammation plays a role in the pathogenesis of this type 2 DM complication. Recent studies showed neutrophyl-lymphocyte ratio (NLR) is a potential inflammation marker. Early screening for neuropathy is an important part of the medical rehabilitation management of this condition.

Material and methods: This study uses data analysis independent sample T-2 test with a significant (p<0.05). This study is a analytic observation cross-sectional study with type 2 diabetic male subjects, screened with Michigan Neuropathy Screening Instrument then divided into 2 groups, with DPN group (11 subjects) and without DPN group (7 subjects). This was followed with complete blood count laboratory testing (neutrophyl and lymphocyte level) and NCS to measure distal latency, amplitudo, and NCV of the tibial, peroneal, and suralnerve on both lower extremities.

Result: There were 18 subjects in this study. Independent T-2 test showed that there was no significant difference in neutrophils (p=0.679), lymphocytes (p=0.127), and NLR (p=0.190) in the DM group without or with neuropathy. NCS showed that there were significant differences on the amplitude of the three nerves peroneal (p=0.003), tibial (p=0.017), sural (p=0.033), also in NCV of peroneal (p=0.001) and tibial (p=0.008). There were no significant differences found on the three distal latency of peroneal (p=0.074), tibial (p=0.151), sural(p=0.294), and NCV of sural (p=0.262).

Conclusions: This study shows that there is no significant difference in NLR on both groups. There were significant differences in the amplitude of the three peroneal, tibial, and sural nerves and the conduction velocity of the peroneal and tibial nerves. However, there was no significant difference in the distal latency of the threeperoneal, tibial, sural, and the NCV of the sural nerves.Keywords: diabetes melitus, diabetic peripheral neuropathy, nerve conduction studies, neutrophyl-lymphocyte ratio, rehabilitation management.

The Kazakh sheep is native to China. The breed has many advantages, including its size, hardiness, and good meat production, it has the economic disadvantage of having a low reproductive rate. Inhibin-α (INHα) regulates the synthesis and secretion of follicle-stimulating hormone (FSH) and could feasibly be used to boost reproduction in the Kazakh sheep. However, the current methods of INHα preparation are both costly and time-consuming. Here, we investigated the effects of INHα on Kazakh sheep reproductive performance by immunization with INHα and analyzing the subsequent changes in reproductive hormone levels and blood biochemical indices. An anti-INHα polyclonal antibody was raised in camel. It and a recombinant INHα protein were used to immunize groups of adult Kazakh sheep in anestrus. Reproductive hormones (FSH, luteinizing hormone [LH], progesterone [P4], and estradiol [E2]) were measured by ELISA, together with the measurement of changes in INH levels and blood physiological and biochemical indicators. The blood levels of LH and P4 in the sheep immunized with the camel anti-INHα polyclonal antibody (group A) did not differ significantly from those in the recombinant INHα protein (group B) and the control group (group C) (P ＞0.05). FSH and E2 levels in group A were significantly higher than the controls (P <0.05) and the INH concentrations were significantly lower than those in group C (P <0.05). There were no abnormalities in the blood biochemical indices in groups A, B, and C.In conclusion, immune INHα preparations significantly affected the blood reproductive hormone levels of Kazakh sheep. This technique has potential application for improving the reproductive performance in these sheep and is also relevant for future research into the development of an INHα vaccine.
