Published: October 2023

Abstract
To solve the problem of severe physical resource depletion in cloud data centers, a virtual machine placement method based on an improved sparrow search algorithm is proposed. Firstly, Chebyshev chaotic mapping and Levy flight disturbance strategy are integrated into the sparrow search algorithm to improve the allocation of population resources in the search space and increase the diversity of population search. In addition, a mapping encoding scheme is designed to map the virtual machine placement scheme into continuous position information, Finally, a cloud data center resource consumption model was established with the objective function of maximizing the utilization efficiency of physical machine resources. The simulation results show that this method has better performance in virtual machine migration and physical resource utilization, and the Service Level Agreement (SLA) violation rate is basically stable.

Abstract
Wastewater containing heavy metal ions poses great harm to human health and the environment. The adsorption materials used in traditional adsorption methods, such as starch and cellulose, are prone to hydrolysis, causing secondary pollution to water bodies. Nylon@Fe3O4@PAA adsorption material is obtained by using nylon as a substrate, activating nylon with sodium carbonate/hydrochloric acid, depositing a Fe3O4 magnetic layer by coprecipitation, and grafting polyacrylic acid. The adsorption material is used to explore the effects of different conditions (adsorption material dosage, Cu2+ concentration, pH value, and adsorption time) on the adsorption efficiency, adsorption capacity, and total adsorption amount of copper ions through changing the adsorption conditions. The research results showed that the adsorption material dosage is 18.75 mg (suspension solution with a concentration of 62.5 mg/mL is added with 300 µL), the concentration of Cu2+ solution is 20.48 mg/L, the adsorption time is 60 min, and the pH value is 9. The optimal adsorption efficiency is 82.29%, the optimal adsorption capacity is 154.87mg/g, and the optimal total adsorption amount is 343.91 mg. After fitting thermodynamic and kinetic equations, the adsorption process of nylon@Fe3O4@PAA for Cu2+ ions dominated by chemical adsorption, with good adsorption rate and adsorption performance.

Abstract

Fuzzy c-means (FCM) is an effective clustering algorithm, which has been successfully applied on many real-world applications. Although, FCM and its improvements have achieved considerable performance however, most of the FCM-based methods consider equal importance for all features and neglect the feature weights in the clustering processes. To deal with this issue, in this paper, two methods called Local Feature Weighting FCM method (LFWFCM) is proposed and Robust Local Feature Weighting FCM (RLFWFCM) are proposed. RLFWFCM employs a non-Euclidian and robust metric in its process to overcome the presence of noise or outliers in data. Also pure mathematical analyses are provided to show the convergence properties of these methods. Also, these methods have been applied on the Hadoop platform by mapping reduction programming method. To assess the effectiveness of these methods, several experiments are performed on both real-world and synthetic datasets. The obtained results demonstrate the effectiveness of the proposed methods in comparison with some baseline and state-of-the-art clustering methods.

Abstract

IBS/CAPP in South Korea is home to multiple active axion search experiments using cavity haloscopes that operate within the frequency range of 1-6 GHz. The haloscopes convert axions to photons, resulting in an output power of about 10-24 to 10-22 W. To detect such a small signal amidst noise, quantum-limited noise amplifiers and ultra-low-temperature environment (∼10 mK) are required for all critical read-out components to minimize noise from all of active and passive lossy components. Additionally, operating at low dissipation levels is necessary to maintain the haloscope and amplifier at a temperature of 25-40 mK. Our primary objective is to achieve the highest possible scanning-frequency speed, which includes the time for maintenance and system calibration.
For the CAPP-MAX flagship experiment, we achieved a record speed of 3 MHz/day for the DFSZ-level axion sensitivity during uninterrupting measurements. This paper presents the development and operation of low-noise amplifiers for five haloscope experiments targeting different frequency ranges and provides design, operational, and performance details of the amplifiers.

Authors: Abdullah Arshad Mohammad 
Published: October 2023

Abstract
Background: Vegetables play a crucial role in human nutrition, forming a significant part of our daily diet. Nevertheless, the consumption of vegetables stands out as a primary pathway for the transmission of intestinal parasites to humans.
Objective: The objective of this study was to explore the presence of parasitic helminths responsible for contaminating vegetables in Duhok city, Kurdistan Region of Iraq.
Methods: In the present study, spanning from June 2021 to August 2021, which 126 samples of fresh vegetables, including Coriander, Dill, Lettuce, Pepper, Parsley, and Radish were collected from various places in Duhok city. These samples underwent microscopic examination to investigate the presence of parasites.
Results: The study revealed that 15.9% of the vegetables were contaminated with parasitic helminths, but there was no significant difference between the contaminated and non-contaminated vegetables, as indicated by a p-value of 0.628. Three varieties of parasitic helminths were identified in the vegetable samples, namely Ascaris lumbricoides (7.9%), Enterobius vermicularis(6.3%), and Hymenolepis nana (2.4%). The highest incidence of parasitic helminths contamination was observed in Parsley (23.8%) and Lettuce (20%), while Pepper showed a lower contamination rate of 4.8%.
Conclusion:This study has revealed a moderate rate of contamination of fresh vegetables with parasitic helminths. This contamination can potentially serve as a significant factor in the transmission of pathogenic intestinal parasites.

Published: October 2023

The rise of construction projects and population growth, followed by the expansion of industry and any other sectors such as housing estate, offices, and transportation, can lead to not only economic growth but also negative impacts such as air pollution, including nitrogen dioxide (NO2) pollutants. According to KEP-45/MENLH/10/1997, air pollution can be determined by The Pollutant Standards Index (PSI). The statistical analysis result employing the multivariate ANOVA test with the Anderson-Darling method showed the impact of NO2 concentrations on four location points over two years. Meanwhile, the data result of PSI revealed a high level of ambient air NO2 in Lampung Barat Regency, particularly at the monitoring point of offices. On the other hand, in Way Kanan Regency, the level of ambient air NO2 tends to be safe and secure at the monitoring point of industry and transportation. The factor of sampling location and technique (stage 1: dry season, stage 2: rainy season) did not give a significant effect on the NO2 level due to a p-value ≥ 0,05. However, the sampling point (of monitoring) influenced the NO2 level for p-value ≤ 0,05 in Lampung Barat and Way Kanan Regency in 2019-2020 which was still claimed as safe and secure based on PP No. 41 in the Year 1999, which sets the required limit at 100 g/m3.

Published: October 2023

Abstract

Fresh water is vital for the survival of life. Rivers are the primary source of freshwater supply. However, over the past few decades, challenges concerning the sustainability of rivers and maintaining their water quality have become countless. Due to rapid and unrestrained advancements, the river ecosystem becomes imbalanced. To assess and predict water quality from the real data collected, it becomes necessary to devise ways to interpret and analyze the data efficiently. The present work deals with the development of a water quality index based on a fuzzy approach for predicting the water quality of the river Yamuna. The most contaminated stretch of the river through Delhi has been taken up for this study. The proposed methodology is elementary, simple, effective, and flexible in assimilating uncertainties involved in complex water management problems. The suggested index involves the most dominant parameters and can act as a practical tool for routine water quality assessment. The outcomes of the study give pronounced facts to water authorities about the awful condition of the river Yamuna in Delhi.

Abstract:
We have reviewed the potential use of bioactive peptides in the treatment of gastrointestinal (GI)
malignancies, which are a significant cause of morbidity and mortality globally. Conventional therapies, such
as surgery, chemotherapy, and radiotherapy, are associated with numerous side effects that may lead to longterm
complications. Bioactive peptides are short-chain amino acids that can be extracted from natural sources
or synthesized, and they have various potential health benefits, including anti-inflammatory, anti-hypertensive,
antioxidant, antimicrobial, and anti-cancer properties. Bioactive peptides can be acquired from animal or plant
sources, and can be classified based on their function, such as ACE-inhibiting, antimicrobial, and electrolyte-
regulating peptides. Recent studies have demonstrated the promising role of bioactive peptides in tumor
suppression, especially when combined with conventional therapies. In this study, we have reviewed the beneficial
properties of bioactive peptides and their role in suppressing tumor activity. The mechanisms of bioactive
peptides in tumor suppression are discussed. We have further reviewed the findings of preclinical and clinical
studies that have investigated the application of bioactive peptides in the treatment of GI cancers. This review
highlights the potential use of bioactive peptides as a promising treatment method for GI malignancies to
increase the quality of life of GI cancer patients.

Published: October 2023

Abstract:
Plants have been used since the earliest times to manage various diseases, and many
of these plants are being used as conventional remedies for various disorders today. Biologically
active ingredients isolated from medicinal plants and extracts are receiving a lot of attention these days, partly because modern-day medication has a lot of side effects and somewhat because
pathogenic microorganisms are becoming more resistant to antibiotics and many other treatments. Artemisia is the broadly dispersed genus of the family Asteraceae and encompasses almost five hundred species. Amongst these species, Artemisia absinthium L. is a familiar herb
called Wormwood in English and Urdu, generally known as Afsanteen. In history, this species
was recognized as important, and in old Europe, it was called “the most important master
against all exhaustion”. A. absinthium has various benefits in treating pathological conditions
such as gastric problems, fever, inflammation, and urinary disorders. The official European medicine uses A. absinthium in both allopathy and homeopathy. The herb was used to treat bladder
diseases, anemia, helminthiasis, insomnia, fever, and trouble healing wounds and to treat gastrointestinal disorders in Asian and European traditional medicine. Mono and sesquiterpenes are the
major pharmacologically active constituents of A. absinthium. Wormwood is a valuable resource
of chemically new constituents and requires comprehensive screening approaches to emphasize
the phytoconstituents and pharmacological actions at the molecular level. The core focus of this
review is to provide complete information about the scientific evidence-based pharmacological
activities, traditional uses, and phytoconstituents from A. absinthium. The collation of literature
has been done by using references from main databases such as PubMed, Research gate, Scopes,
Science Direct, Google Scholar, Chemical Abstracts, Phytochemical and Ethnobotanical Databases, Medicinal and Aromatic Plants Abstracts, classical books, and pharmacopeias.

Rabies is a viral, lethal, and zoonotic disease with worldwide distribution, primarily transmitted through bites from infected dogs and bats. The Biosafety Laboratory (LSE-LANASEVE) of the Animal Health Service of Costa Rica (SENASA) serves as the national reference laboratory for diagnosing rabies in humans and animals. Since regional laboratories lack the equipment for the direct fluorescent antibody test (FAT), we evaluated the rapid immunochromatographic diagnostic test (RIDT) from BioNote, employing FAT as a reference, to improve rabies diagnosis. We analyzed 193 brain tissue samples between 2014 and 2019. Out of these, 174 came from species that RIDT has been validated for: bovines (162), dogs (10), and raccoons (2). The rest were from unvalidated species, including horses (7), humans (1), and others. Among the 174 validated samples, 26 bovine samples were positive for both RIDT and FAT. Reviewing all 193 samples, 28 were positive and 165 negative using both methods. Two horse samples presented inconsistencies, being positive on FAT but negative on RIDT; these were subsequently verified as false negatives by RT-PCR. RIDT exhibited a sensitivity of 94 % (CI95, 83.9-102.3), specificity of 100 %, positive predictive value (PPV) of 100 %, and negative predictive value (NPV) of 99 % (CI95, 97.1-100.5). RIDT has demonstrated reliability in quickly diagnosing rabies for validated species. We advise its application in SENASA's regional laboratories for those particular species. If there's uncertainty, samples should be sent to LSE-LANASEVE for FAT or RT-PCR confirmation.
Genetic, virological, infectious, and pharmacological risk factors for CD4<sup>+</sup> T-cell regeneration failure in HIV-infected subjects receiving ART
Authors: Saidakova E. V. 
Published: October 2023

In 10 to 40% of HIV-infected patients being adherent to highly active antiretroviral therapy (HAART), viral load suppression is not accompanied by a significant increase in the number of CD4+ T-lymphocytes. This phenomenon, known as immunological non-response to treatment, is associated with a high risk of developing AIDS-associated and non-AIDS-associated diseases, as well as premature death. The bases of immunological non-response to HAART are poorly understood, while information on the risk factors for its development is scattered.The aim of the present review is to organize data on non-immune-system risk factors for the development of immunological nonresponse to HAART.Materials and methods. Electronic searching using PubMed, Science Direct, and Scopus were conducted.Results and discussion. The database search delivered information on genetic, virological, infectious, and pharmacological risk factors for the development of immunological non-response to HAART. Each factor contribution might be substantially different. Still, none of them can be considered a trigger mechanism for this phenomenon.Conclusion. Immunological non-response to HAART is a polyetiological condition. Apparently, this phenomenon is based on normally imperceptible immune system features or defects, which manifest during the CD4+ T-cell regeneration.

Published: October 2023

Adolescent and young adults (AYAs) belong to a unique category of
patients diagnosed with acute lymphoblastic leukemia (ALL) who have
better outcomes when treated with pediatric-inspired regimens.
Bloodstream infections (BSIs) is a leading cause of treatment-related
mortality in ALL patients. However, the epidemiology and prognostic
characteristics of BSIs in ALL patients with AYAs remain unclear. In
this study, we analyzed the epidemiology and prognostic factors of AYAs
and compared the similarities and differences between younger and older
adult patients with BSIs. We analyzed the clinical data of three
comprehensive hospitals in Hunan Province, China, from January 2010 to
August 2021. In this study, the clinical characteristics and pathogen
distributions of AYAs patients were similar to those of adult ALL
patients. Extended-spectrum beta-lactamase(ESBL)-producing bacteria were
more commonly found in AYAs than in children (32.8% vs. 16.4%,
P=0.09). Regarding prognostic factors, the length of hospitalization
(>14 days) and renal inadequacy (creatinine≥177μmoI/L) were
risk factors for 30-day mortality in AYAs with BSIs. In our study, AYAs
patients with BSIs showed clinical characteristics and pathogen
distributions similar to those of adult patients, but were quite
different from those of children.

Authors: Benítez Guadarrama Juan Pedro 
Published: October 2023

En la actualidad el uso de aplicaciones móviles y simuladores juegan un papel muy importante en el proceso educativo, pues permiten desarrollar estrategias, habilidades y actitudes en las personas que lo utilizan y dan oportunidad de mejora para el proceso de capacitación. Por ello, el objetivo de esta investigación fue desarrollar un proceso de capacitación para mipymes que implemente el uso de aplicaciones móviles en entornos virtuales para fortalecer su estructura administrativa y financiera. Para el estudio se aplicó la metodología DCIERC, y se realizó un estudio cualitativo, descriptivo, de corte transversal. Los resultados muestran que el proceso de capacitación y el uso de la tecnología móvil con escenarios virtuales preconfigurados pueden mejorar el desempeño de las mipymes durante sus operaciones reales.
Se infiere, además, que la metodología DCIERC durante la capacitación es un recurso viable, ya que se observa que al contener la teoría y legalidad sobre las actividades o funciones preconfiguradas desarrolladas antes y durante la práctica real fortalecen el aprendizaje y contribuyen al proceso efectivo de capacitación. Esto se debe a que el emprendedor puede aplicar sus conocimientos empíricos o previos relacionándolos con lo aprendido y lo transpone en un conocimiento efectivo. De esta manera evita incurrir en errores, pues puede evaluar el desempeño de los emprendedores para conocer las discrepancias teóricas y prácticas en el momento de la aplicación de sus conocimientos en las actividades. Además, al hacer una retroalimentación del análisis de la evaluación en su integración promueve la mejora continua y los objetivos empresariales.
Realidad y Representación en Habermas y Rorty
Authors: Galán Vélez Francisco Vicente 
Published: October 2023

El artículo analiza la postura que Habermas llamó realismo sin representacionismo, cuyo fundamento es el pragmatismo kantiano y el naturalismo débil. Habermas otorga a la acción cotidiana el papel que Kant asigna a las condiciones trascendentales. Asume el giro lingüístico, pero evita una interpretación contextualista de la razón como Rorty, para quien el anti-representacionalismo es necesariamente anti-realista. Para Habermas nuestros aprendizajes continúan el proceso evolutivo, y suponen una realidad independiente y común a todas las formas de vida, aunque no debemos identificar esta realidad con ninguna conceptualización de ella. El artículo cuestiona si este realismo ofrece una diferencia significativa con el pragmatismo de Rorty.

Published: October 2023

Aplikasi Fiber Reinforcement Polimer (FRP) sebagai tulangan menjadi salah satu inovasi baru untuk sistem beton bertulang. FRP atau serat berpolimer merupakan material dengan sifat elastis dan mempunyai kuat tarik yang lebih tinggi dibandingkan baja. Selain mempunyai kelebihan sifat mekanika, FRP juga memiliki sifat tahan korosi, dan sifat non-magnetik, yang dapat memperlambat deteriorasi material akibat lingkungan. Pemodelan balok bertulangan FRP secara numeris dengan finite element perlu dibuat untuk menggantikan pengujian ekseperimental. Dalam penelitian ini dilakukan pemodelan elemen balok lentur dengan perangkat lunak ABAQUS CAE. Dimensi balok 150 mm x 100 mm, panjang 2400 mm dengan tulangan memanjang jenis glass fiber reinforcement polimer (GFRP) tekan dan tarik masing - masing 2D10 dan sengkang D4-100 dengan pembebanan statik four point loading. Dalam pemodelan digunakan interaksi perfect bond antara GFRP dan beton sekelilingnya. Untuk validasi pemodelan, kurva beban - defleksi hasil pemodelan dibandingkan dengan kurva beban – defleksi hasil pengujian eksperimental sebelumnya. Hasil model tervalidasi relatif baik dibandingkan hasil eksperimental. Dengan hasil pemodelan yang sudah tervalidasi, beban maksimum model numerik dibandingkan dengan analisis kapasitas lentur nominal SNI 8970 : 2021 sehingga didapatkan rasio perbandingan kapasitas nominal dan beban maksimum model numerik. Diagram beban-defleksi di awal sangat dekat, dengan selisih beban ultimit pada model dengan hasil pengujian lentur balok 12,1%. Perbandingan kapasitas lentur nominal bertulangan GFRP berdasarkan SNI 8970:2021 dan beban maksimum model numerik diperoleh 0,5, aman digunakan sebagai acuan perencanaan balok beton bertulangan.
