Authors: BADDAL Buket , BOSTANCI Aysegul , SÜER Kaya
Published: September 2023

Aseptic meningitis caused by Varicella-Zoster virus (VZV) is a rare phenomenon in the healthy population. Immunocompromised patients are predominantly affected by viral reactivation, characterized by rash and neurological symptoms, and meningitis as a rare complication. Herein, we report two cases of VZV meningitis in adult patients without rash and fever over a 4-month period. The first case was an immunocompetent 37-year-old male who presented with persistent headache, agitation and unclear speech. The second case was an immunocompromised 76-year-old male who was admitted to the emergency department with confusion, disorientation, dizziness, loss of consciousness, pain in the lower left extremities and difficulty in walking. Cerebrospinal fluid (CSF) analysis in both patients revealed a high leukocyte cell count with 97% lymphocytes. CSF gram staining and culture were negative. CSF polymerase chain reaction (PCR) analysis indicated VZV infection. Both patients were administered acyclovir for 14 days and were discharged without any neurological sequela. This case report series highlight the presentation of VZV as aseptic meningitis in both immunocompetent and immunocompromised patients without the typical clinical symptoms and should always be considered by the clinicians.

Objective: This study aimed to investigate the effects of DPP-4 inhibitors on kidney function in type 2 diabetes mellitus patients with stages 3-5 chronic kidney disease, focusing on estimated glomerular filtration rate and proteinuria.

Methods: This is a retrospective case-control design, and data were collected from a single hospital's software and the Turkish Ministry of Health's National Data Tracking System. Diabetic patients with T2DM and CKD stages 3-5 were included, with dipeptidyl peptidase-4 inhibitor users (n=118) and non-users (n=48) forming the intervention and control groups, respectively. Baseline demographics, clinical characteristics, and outcomes were compared between groups.

Results: At baseline, both groups demonstrated similar age, gender distribution, body mass index, and eGFR. Over a 12-month follow-up, while slight improvements in eGFR were observed in the intervention group and minor reductions in the control group, these changes did not reach statistical significance (p>0.05). Proteinuria showed a stable trend in the intervention group, whereas a significant increase was noted in the control group (p=0.035). Age significantly correlated with eGFR (p

O reconhecimento de pessoas, enquanto meio de prova, é recorrente aos procedimentos investigatórios, sejam eles, de natureza comum ou militar. Senão, um dos mais usuais, pois, presta-se a firmar a autoria delitiva e a comprovação da materialidade dos fatos. Assim, desta maneira, encontra-se normatizado no Código de Processo Penal e, no seu congênere Castrense, o Código de Processo Penal Militar. Até a pouco, a Corte Superior e a doutrina consideravam estas regras processuais como mera orientação e recomendação, bem por isso, sua inobservância não acarretava a nulidade do reconhecimento, pois mantinha a prova como válida. Recentemente, houve significativa mudança de rumo, dado a julgamentos do Superior Tribunal de Justiça, agora, àquelas regras processuais são requisitos mínimos, do contrário, a prova é nula. Vale salientar que tal prova recorre da memória da vítima e/ou testemunha, a qual, pode sofrer interferências ambientais e de contexto e, por isso, sua captação e absorção resta variável e pode se enfraquecer com o tempo, de sua sorte, recomenda-se a produção, cronologicamente elencando, o mais próximo possível dos fatos, ou seja, no processo investigativo. Mas, negligências procedimentais levaram a erros judiciais, motivo desta inflexão e, após, estudos de grupo de trabalho do Conselho Nacional de Justiça (CNJ), firmou-se a Resolução nº 484/2022. Inobstante às considerações de sua origem, vê-se que tal instituto não conflita com a legislação, mas sim, busca elevar o grau de confiabilidade da prova. Resta, agora, considerar em que medida tal Resolução incide nos feitos processuais da Polícia Militar do Paraná e, ao fim, propor uma maneira de pacificar o tema para evitar nulidade dos atos de reconhecimento de pessoas.
PENGARUH RASIO L/D ANTARA LAPISAN MORTAR GEOPOLIMER BERBAHAN DASAR FLY ASH TERHADAP KUAT TEKAN BETON DENGAN SEAWATER CURING
Authors: Nastiti Syahidah Fani
Published: September 2023

ABSTRAK

The performance and durability of concrete in construction is essential to maintain the sustainability and protection of the material. Particularly in construction in marine environments, the attack of aggressive chemical compounds can affect concrete and accelerate deterioration. This research aims to improve the performance and durability of concrete in construction in marine environments by using additional protection methods such as Surface Applied Protection. One of the materials used is geopolymer mortar that uses fly ash as a base material. This study shows that geopolymer mortar contributes positively to the compressive strength and durability of concrete. The thickness of the geopolymer mortar layer affected the mechanical properties of the concrete, and 4 cm thick gave the highest compressive strength results. The addition of geopolymer mortar needs to be adjusted to the compressive strength of the concrete and pay attention to the layer thickness for optimal results.

Технологические схемы очистки дождевых и талых сточных вод были разработаны в 1960–1980-х годах и на сегодняшний день не всегда эффективны. На очистных сооружениях аэропортов, предприятий жилищно-коммунального хозяйства, железнодорожного транспорта и других объектов компания успешно применяет усовершенствованную технологию очистки сточных вод, используя оборудование собственного производства. В отличие от традиционной схемы, в очистных сооружениях применяется метод динамической сепарации стоков, т. е. одновременное отделение нефтепродуктов и взвешенных веществ из воды.

Developed in 1960–1980s process flow schemes for the purification of rainfall and snow-melt waters are not always effective nowadays. At the treatment facilities of airports, housing and public utilities, railway transport, etc., the company successfully applies advanced wastewater treatment technology using equipment of its own production. Instead of the traditional scheme, the treatment facilities use the method of dynamic separation of wastewater, i. e., the simultaneous separation of oil products and suspended solids.

The volume of waste will continue to increase with increasing time, population, and economic growth in a city, district, or province. The city of Jayapura, as the center of the economy of the land of Papua, is the same way. The Koya Koso TPA management system for Jayapura City is currently landfill control, where the waste that has been collected at the TPA is stockpiled using layers of soil so that the piles are increasing in number day by day and causing problems including air pollution by methane gas, CO2, and other gases and limited land, thereby reducing the age of TPA Koya Koso Jayapura City. This study aims to determine the potential content of methane gas by modeling it using Landgem software and the potential capacity of electrical energy that can be generated. The results showed that the potential content of methane gas generated from Landgem modeling is 13,134,026 m3/year, or 8,762 tons/year, resulting in a potential capacity of electrical energy of 2,797.22 kW, or 2.8 MW.
Commercial Electric Vehicle Fleets Participating in Ancillary Services Markets: A Stochastic Analysist o Inform Rate Modifications
Authors: Owens James , Schittekatte Tim , Gençer Emre
Published: September 2023

Vehicle-to-grid (V2G) has massive potential to make transportation decarbonization more economically attractive while bolstering the broader power system. Here we discuss how traditional electricity retail rate design can render the business case of commercial fleet electrification in the United States less attractive by disincentivizing V2G participation. We tackle this issue bottom-up by introducing a high-resolution stochastic model to examine tariffs' impacts on charging and frequency regulation bidding for a delivery fleet housed at a large warehouse. Using data from California for the rate design and frequency regulation prices, we show that absent a rate redesign, opportunities for both fleets and the grid are missed out. We propose a rate modification: demand charge relaxation during off-peak, overnight hours. This enables fleets to shift additional load share to overnight hours and substantially increase ancillary service revenues, with no impact expected on the local grid cost driver, i.e., the coincident peak load. Applying this change to a Pacific Gas and Electric tariff, we observe daily regulation capacity bids of ~5 MW and operational savings of 7.5% and 20.6% for a 20 EV and 60 EV fleets, respectively. Savings are driven by capacity revenues for smaller fleets and deferred demand charges for larger fleets.
Traffic-Aware Optimal Multi-Beam Resource Allocation in 5G Networks Impaired by Rain and Foliage

Published: September 2023

In this work, we investigate a novel framework for a traffic-aware multi-beam optimal resource allocation to serve fixed home users distributed over a geographical area in the presence of rain and foliage. The fixed home users in the geographical area of interest are served by small-cell next-generation node B (gNB) via multiple beams generated simultaneously by the uniform planar array (UPA) installed at the gNB. In this regard, we present a framework to compute the optimal coverage radius of the gNB to satisfy the desired quality of service (QoS) requirements of the users. We also derive the closed-form expression for the optimum coverage radius of the gNB, considering free space and foliage attenuation scenarios. We propose a graphical methodology to compute the optimal radius of gNB in free space propagation, rain, and foliage attenuation. Further, based on the location information of the users, we determine the optimal location of the gNB by leveraging the unsupervised machine learning (ML) framework. Finally, we investigate a non-linear programming (NLP)-based technique for allocating optimal power and bandwidth to each beam, constrained by total power and bandwidth availability at the gNB. The optimal beam resource allocation (power and bandwidth) strategy ensures that the requested data rate (traffic demand) is satisfied for each user served by each beam. The simulation results demonstrate the effectiveness of our proposed methodology to ensure high QoS for a larger number of users in the presence of rain and foliage as compared to genetic algorithm and surrogate optimization

Crowdsourced Estimation of Collective Just Noticeable Difference for Compressed Video with Flicker Test and QUEST+
Authors: Jenadeleh Mohsen , Hamzaoui Raouf , Reips Ulf-Dietrich , Saupe Dietmar
Published: September 2023

The concept of video-wise just noticeable difference (JND) was recently proposed to determine the lowest bitrate at which a source video can be compressed without perceptible quality loss with a given probability.

This bitrate is usually obtained from an estimate of the satisfied used ratio (SUR) at each bitrate, respectively encoding quality parameter. The SUR is the probability that the distortion corresponding to this bitrate is not noticeable. Commonly, the SUR is computed experimentally by estimating the subjective JND threshold of each subject using binary search, fitting a distribution model to the collected data, and creating the complementary cumulative distribution function of the distribution. The subjective tests consist of paired comparisons between the source video and compressed versions. However, we show that this approach typically over- or underestimates the SUR.

To address this shortcoming, we directly estimate the SUR function by considering the entire population as a collective observer. Our method randomly chooses the subject for each paired comparison and uses a state-of-the-art Bayesian adaptive psychometric method (QUEST+) to select the compressed video in the paired comparison.

Our simulations show that this collective method yields more accurate SUR results with fewer comparisons.

We also provide a subjective experiment to assess the JND and SUR for compressed video. In the paired comparisons, we apply a flicker test that compares a video that interleaves the source video and its compressed version with the source video. Analysis of the subjective data revealed that the flicker test provides on average higher sensitivity and precision in the assessment of the JND threshold than the usual test that compares compressed versions with the source video. 

Using crowdsourcing and the proposed approach, we build a JND dataset for 45 source video sequences that are encoded with both  advanced video coding (AVC) and versatile video coding (VVC) at all available quantization parameters.  Our dataset is available at http://database.mmsp-kn.de/flickervidset-database.html.

We present our findings on the utilization of a high permittivity dielectric, RESURF, in β-Ga2O3 trench Schottky barrier diodes. Our research demonstrates the achievement of ultra-low reverse leakage current in both small -scale and large-scale devices, with a breakdown voltage exceeding 1kV, thanks to the high-k RESURF technology. Furthermore, we assess the switching performance of these large-area devices and illustrate their competitive standing when compared to state-of-the-art commercial SiC devices. Additionally, we provide evidence of the superior thermal stability exhibited by high-k trench devices in comparison to SiC devices.
An Autoencoder with Convolutional Neural Network for Surface Defect Detection on Cast Components
Authors: Chamberland Olivia , Reckzin Mark , Hashim Hashim A
Published: September 2023

There is unrealized potential in using automation to alleviate the visual inspection associated with non-destructive testing in manufacturing facilities. The identification of defects during the production can help avoid substantial manufacturing errors by indicating that preventative maintenance should be introduced. The use of an autoencoder for this application reduces the need to generate datasets for various defect types, instead only one training dataset would be needed. To address this, this paper proposes a Convolution Neural Network (CNN) autoencoder approach to detect surface defects on cast components during the production. The proposed method categorizes the data into damaged and undamaged components by clustering based on the loss associated with the reconstructed image. The average F1-score and accuracy from retraining the model 10 times was 89.14% and 88.52% respectively. Although previous studies have obtained higher metrics, they have focused their efforts on supervised training techniques where as this research proposes an unsupervised training method with results comparable to the previous studies.
A Benchmark of Integrated Magnetometers and Magnetic Gradiometers
Authors: Close Gael
Published: September 2023

This survey paper compiles and benchmarks the performance of integrated magnetic sensors, in terms of their noise and full-scale magnetic field. In total, we collected performance metrics of 31 sensors realized in various technologies. For each sensor, we derived a noise model to estimate the noise under the same conditions. We obtained a comprehensive benchmark with a focus on integrated devices. We also measured the noise spectrum of 11 of those sensors to confirm our noise model. Given that for many emerging applications, such as tactile, current, torque and biomagnetic sensing, the signal of interest is the field gradient to reject magnetic stray fields, we extended the benchmark to gradiometers. We developed a low-noise measurement setup and a low-field gradient (full scale: 10 μT/mm) generation setup to characterize magnetic gradiometers in this regime. The paper discusses the key sensor trade-off between precision and range, and summarizes the technology trends graphically on a trade-off curve, providing broad insight. This paper has been ACCEPTED for publication in IEEE Access.
RSSNet: A Fine-tuned Deep Learning Network for Robotic Surgical-tool Segmentation
Authors: Janjua Muhammad Sadaqat , Ali Hussam , Farooq Qaisar
Published: September 2023

Robotics have significantly transformed surgical practices by improving precision and minimizing invasiveness. Accurate segmentation is crucial to the surgical systems, which remains challenging due to the complex and diverse nature of surgical scenarios and equipment. This paper presents a more robust architecture, the Robotic Surgical-tool Segmentation Network (RSSNet), to enhance the accuracy metrics of surgical-tool segmentation in robot-assisted surgery. The proposed RSSNet model combines the power of Atrous Spatial Pyramid Pooling (ASPP) with the efficiency of average pooling parameter to extract fine details through multiscale manifold convolution kernels for accurate segmentation of diverse-scale instruments. The proposed method outperformed the base U-Net architecture for the enhancement to segment biomedical images with surgical toolsets with intricate details. The model was rigorously tested on three primary datasets, Kvasir-Instrument and EndoVis 2017 & 2018, demonstrating robustness and versatility. An ablation study further confirmed the effectiveness of each component in the model architecture, particularly for generalizability. This study offers an effective, and high-performance low-end solution for surgical tool segmentation, an essential step toward fully autonomous robotic surgeries. Compared with the U-Net baseline method, our proposed method improved the Dice coefficient (DSC) by 5.93% and the mIoU by 6.84% due to multi-scale kernel processing with different dilation rates. While juxtaposed with the best model yet, i.e., Surg_Net, the DSC of the proposed method increased by 1.01%, and mIoU by 1.04%.

have many mechanisms for antibiotic resistance and their ability to produce biofilm and gain

various genes through integrons, that will lead to difficult treatment. Consequently, the acquisition

of the mecA gene made it more virulent and resistant to antibiotics, and this indicates that the

spread of these bacteria in human and animal communities besides health institutions and their

frequent transmission between these communities may have a problem of dealing with it.

Published: September 2023

In response to the COVID-19 pandemic, the South African government enforced a strict lockdown during March and April 2020. Strategies to assist people with maintaining physical activity (PA) became important, and online fitness communities (OFC) offered virtual assistance. This study aimed to investigate the benefits of participating in OFC on physical and mental health during lockdown level 5 in South Africa. The study utilised an online survey which included the Godin Leisure-Time Questionnaire. Participants maintained PA before and during lockdown (n=335; p=0.5). However, significant declines in PA were reported for those who did not find an OFC helpful in achieving exercise goals (p=0.004), nor motivating in pursuing fitness (p=0.001), and not helpful in alleviating perceived feelings of depression and/or anxiety (p=0.001). Participants who indicated that lockdown positively impacted motivation and that OFC were motivating in achieving fitness goals showed a significant improvement in PA (p=0.003). The proven effectiveness of OFC should encourage all health and fitness practitioners to integrate them for current and future use.

The study aimed to determine the participation patterns in active recreation of undergraduate students at a South African university and to what degree they experience leisure boredom. A once-off cross-sectional design consisting of a sample of 581 students was used. Questions related to demographic information, participation frequency, participation format and leisure boredom were included. There were statistically significant differences between the gender groups’ participation frequencies in netball (p=0.010) and social dancing (p=0.044). There were statistically significant differences between all racial groups’ leisure boredom (p=0.000). Medium to large practical significant differences were found between Indian/Asian and Coloured (d=0.9), Coloured and White (d=0.7), and Indian/Asian students and African students (d=0.6). Statistically significant differences (p=0.017) for leisure boredom were found in the total sample for all three accommodation types. Most students prefer to participate on their own or with their friends sharing the same interests, but not all on-campus activities cater to individual participation. This could be because students are more likely to choose activities that provide social opportunities, with the social factor as the second highest-rated motivational factor for active recreation participation.

As doenças sexualmente transmissíveis (DSTs) representam um desafio global de saúde pública, exigindo abordagens multifacetadas para diagnóstico e tratamento eficazes. A atuação multiprofissional desempenha um papel fundamental na gestão abrangente dessas doenças, abordando aspectos clínicos, sociais e de saúde pública. Este estudo tem como objetivo realizar uma revisão integrativa da literatura para investigar e sintetizar a contribuição da atuação multiprofissional no diagnóstico e tratamento de DSTs, destacando os benefícios e desafios desse enfoque. A metodologia empregada neste estudo é a revisão integrativa da literatura, que consiste na busca sistemática e na análise crítica de estudos relevantes. Foram consultadas bases de dados eletrônicas, como PubMed, Scopus e Google Scholar, utilizando palavras-chave relacionadas ao tema. Foram incluídos estudos publicados no período de 2010 a 2022 que abordassem a atuação multiprofissional no contexto de DSTs. A atuação multiprofissional no diagnóstico e tratamento de DSTs emerge como uma abordagem eficaz e abrangente. Profissionais de saúde, incluindo médicos, enfermeiros, psicólogos, assistentes sociais e educadores, desempenham papéis complementares na prevenção, diagnóstico precoce, aconselhamento e tratamento das DSTs. Essa abordagem multidisciplinar ajuda a reduzir a disseminação das DSTs, promover a adesão ao tratamento e melhorar a qualidade de vida dos pacientes. No entanto, desafios, como a integração de serviços e a superação de estigmas, também são evidentes. O trabalho conjunto e a formação interprofissional são essenciais para otimizar os resultados.

Published: September 2023

Immunomodulation constitutes a crucial part of individual organisms’ defense systems. Moreover, the utilization of plant-based natural products as herbal medicine for immunomodulation has garnered significant interest. Herein, we examined the immunomodulatory potentials of active phytocompounds extracted from Withania somnifera and Aloe barbadensis by employing ADMET screening, network pharmacology, and molecular docking techniques. This study follows the paradigm in drug discovery, which has shifted from a “one-target, one-drug” mode to a “network-target, multiple-component-therapeutics” mode. Phyto compounds sourced from W. somnifera and A. barbadensis were mined from online databases, including Dr. Duke’s Phytochemical Ethnobotanical Database. After screening these active compounds, their potential targets were predicted through in silico ADMET property prediction models. Network pharmacology was utilized to establish a “compound-protein/gene-disease” network and reveal the regulatory mechanism of small molecules in a high-throughput manner through STRING, Cytohubba plugin in Cytoscape, and the g: Profiler software. A molecular docking simulation was performed to examine the binding affinity between the selected hub targets and bioactives. The findings showed that phytocompounds derived from the W. somnifera and A. barbadensis exhibit immunomodulatory effects by inhibiting specific protein targets, notably AKT1, HCK, JAK2, PDPK1, KIT, and IL2. Molecular docking analysis further revealed the potential of withanolide G, somniferine, and somniferanolide as promising immunomodulatory compounds against HCK, JAK2, and PDPK1 proteins, which are involved in multiple myeloma pathways, encompassing the PI3K-Akt signaling pathway, NOD-like receptor signaling pathway, and Toll-like receptor signaling pathway. In conclusion, these compounds are recommended for further in vivo and in vitro investigations to ascertain their potential as treatments for multiple myeloma.

Yüksək temperatur, təzyiq və kimyəvi aktiv mühitində işləyən neft-mədən və neft-emalı avadanlıqlarının boru xətlərində qısa istismar müddətindən sonra nasazlıqlar müşahidə olunur. Bu boru xətlərinin daxili səthində intensiv korroziya prosesi, yeyilmələr və çatlar əmələ gəlir və onlar sıradan çıxır. Boruları korroziya və digər təsirlərdən qorumaq məqsədi ilə onların daxilinə silisium örtüklər çəkirlər. Lakin bir müddətdən sonra örtükdə mikroçatlar yaranır. Bu mikroçatlar vaxtında aşkar edilmədikdə makroçatlara çevrilir. Boru örtüyündə çatların təyin edilməsi əsasən elektroqığılcım defektoskopu ilə yerinə yetirilir. Müasir tipli defektoskoplar yalnız makroçatları təyin edir və onun yerləşdiyi koordinatları aşkar etmək imkanı verir. Mövzunun aktuallığı onunla izah olunur ki, müasir dövrdə bir çox boru kəmərləri istehsal və istismar zamanı sıradan çıxaraq böyük iqtisadi itgilərlə nəticələnir. Belə hallarda defektləri vaxtından əvvəl aşkar etmədikdə yaranan mikroçatlar makroçatlara çevrilərək sıradan çıxar. Yaranan mikroçatları vaxtında aşkar etmək və onun həndəsi parametrlərini təyin etməklə borunun istismar müddətini artırmaq məqsədəuyğundur. Tədqiqatın predmeti mikrokontrolerlə idarə olunan təkmilləşdirilmiş elektroqığılcım defektoskop qurğusudur. Bu defektoskopda sınaq gərginliyinin qiyməti 40 KV-a qədər artırılaraq 0.3-1.5 mm ölçüdə olan mikroçatları aşkar etmək imkanı verir. Həmçinin “Mikroçatların təyini” adlı proqram təminatı vasitəsi ilə boru daxilində mövcud olan mikoçatların qrafiki təsvirini almaq və operatora boruda yaranmış mikroçatın dərinliyi, eni və uzunluğu haqqında dəqiq məlumat vermək mümkündür. “Socar” və “Xəzər Boru Örtükləri” zavodunda aparılmış tədqiqatlar nəticəsində göstərilmiş proqram təminatı vasitəsi ilə mikrçatların həndəsi parametrləri və yerləşmə koordinatları təyin olunmuşdur. Məqalədə mikroçatlarin diaqnostika prosesinin proqram təminatinın işləmə prinsipi və alqoritmi təsvir olunmuşdur. Beləliklə aprılmış tədqiqat nəticəsində örtüklü boruların daxilində yaranan mikroçatlar erkən aşkar olunmaqla boruların istismar müddəti və etibarlığı 2-2.5 dəfə artmışdı.

Məlumdur ki, müasir dövrün artan tələbatlarının ödənilməsi üçün plastik məmulatlardan istifadə getdikcə genişlənir. Bu plastik kütlələrə ən geniş yayılmış misal polietilen və polipropilendir. Bu da onlar əsasında hazırlanan məmulatlar tərəfindən yer üzərində yüksək miqdarda tullantı əmələ gətirilməsi ilə nəticələnir. Bu səbəblə, onlar əsasında polimer qarışıqların alınması və müvafiq tətbiq sahələrinin müəyyənləşdirilməsi məsələsi çox aktualdır.
Üzərində çalışılmış mövzu istiqamətində polietilen və polipropilen əsasında hər ikisinin müxtəlif miqdar nisbətlərinə uyğun olaraq həlledici mühitində polimer qarışıqlar hazırlanmış, o cümlədən, qamma şüalanmaya məruz qoyulmuş və alınmış nümunələr ultrabənövşəyi-görünən spektroskopiya üsulu ilə xarakterizə edilmişdir. Absorbsiya spektrlərinin müşahidəsi əsasında müvafiq qarışıqlara uyğun maksimumlar təyin edilmiş və əldə edilmiş göstəricilər əsasında hər qarışığa məxsus bir sıra optiki xassələr, o cümlədən, Tauc düsturundan istifadə etməklə qadağan olunmuş zonanın enerjisi təyin edilmiş və müqayisələr aparılmışdır. Bunun üçün absorbsiya spektrləri əsasında elektronun enerjisi üçün qrafik qurulmuş və alınan əyrinin pik nöqtəsinin absis oxundan kəsdiyi hissə qadağan olunmuş zonanın enerjisinin qiyməti kimi götürülmüşdür.
