Background: Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, different animal species have been implicated as possible intermediate hosts that could facilitate the transmission of the virus between species. The detection of these hosts has intensified, reporting wild, zoo, farm, and pet animals. The goal of this study was to determine the seroprevalence of anti-SARS-CoV-2 immunoglobulins (IgG) in domestic dogs and cats and its epidemiological association with the frequency of coronavirus disease 2019 (COVID-19) patients in Villavicencio, Colombia.

Methods: 300 dogs and 135 cats were randomly selected in a two-stage distribution by clusters according to COVID-19 cases (positive RT-qPCR for SARS-CoV-2) within the human population distributed within the eight communes of Villavicencio. Indirect enzyme-linked immunosorbent assay (ELISA) technique was applied in order to determine anti-SARS-CoV-2 IgG in sera samples. Kernel density estimation was used to compare the prevalence of COVID-19 cases with the seropositivity of dogs and cats.

Results: The overall seroprevalence of anti-SARS-CoV-2 IgG was 4.6% (95% CI=3.2-7.4). In canines, 3.67% (95% CI=2.1-6.4) and felines 6.67% (95% CI=3.6-12.18). Kernel density estimation indicated that seropositive cases were concentrated in the southwest region of the city. There was a positive association between SARS-CoV-2 seropositivity in pet animals and their habitat in Commune 2 (adjusted OR=5.84; 95% CI=1.1-30.88). Spearman's correlation coefficients were weakly positive (p=0.32) between the ratio of COVID-19 cases in November 2020 and the results for domestic dogs and cats from the eight communes of Villavicencio.

Conclusions: In the present research cats were more susceptible to SARS-CoV-2 infection than dogs. This study provides the first positive results of anti-SARS-CoV-2 ELISA serological tests in domestic dogs and cats in Colombia with information about the virus transmission dynamics in Latin America during the COVID-19 pandemic.
Relationship between green space near schools with physical activity and body mass index in portuguese adolescents
Authors: Melo Juliana , Ribeiro Ana Isabel , Pizarro Andreia Isabel , Santos Maria Paula
Published: March 2023

Our aim was to determine the relationship between urban green spaces (UGS) number and greenness amount close to school with physical activity (PA) and body mass index (BMI) of adolescents. Participants (n = 194, aged 13–18 years) were recruited in 75 public secondary schools in the Porto Metropolitan Area. We used a self administered questionnaire to obtain information on height, weight, age and sex. PA levels were assessed using accelerometers. UGS number and greenness amount were measured using network buffers by 300, 500, 1000 and 1500 meters around each school, through geographic information system and normalized difference vegetation index (NDVI), respectively. Multilevel regressions were fitted to each green indicator individually. Multilevel models without adjustment showed a direct relationship between PA and NDVI [B = 118.14; 95%CI: 20.71, 215.57] and inverse relationship between PA and UGS number [B = -5.95; 95%CI: -10.06, -1.83] at 300 meters. Multilevel models with adjustment for socioeconomic deprivation showed a direct relationship between BMI and NDVI [B = 83.41; 95%CI: 30.84, 135.98] at 500 meters and a direct relationship between BMI and NDVI [B = 61.68; 95%CI: 3.07, 120.29] at 1000 meters. The present investigation does not support the idea that UGS number and the NDVI close to school promote PA and metabolic health in adolescents, as the results proved to be inconsistent and dependent on the distance threshold used to define geographic proximity.

Published: March 2023

Chest pain and dyspnoea are among the most common complaints seen in the emergency room and each symptom calls for a broad differential diagnosis. Large hiatal hernias are infrequent, but they can lead to atypical symptoms mimicking different cardiovascular, pulmonary and neoplastic diseases. We present two cases of older patients with an apparent left atrial mass on transthoracic echocardiography, which was subsequently identified as hiatal hernia by other imaging modalities. A multidisciplinary team with multimodality imaging is necessary for diagnostic work-up of chest pain and dyspnoea of non-cardiac origin and especially for a suspected mass compressing the heart, causing chest discomfort.

Published: March 2023

Two-photon excited fluorescence microscopy is a widely-employed imaging technique that enables the noninvasive study of biological specimens in three dimensions with sub-micrometer resolution. Here, we report an assessment of a gain-managed nonlinear (GMN) fiber amplifier for multiphoton microscopy. This recently-developed source delivers 58-nJ and 33-fs pulses at 31-MHz repetition rate. We show that the GMN amplifier enables high-quality deep-tissue imaging, and furthermore that the broad spectral bandwidth of the GMN amplifier can be exploited for superior spectral resolution when imaging multiple distinct fluorophores.

The analysis of phyllosphere microbiomes traditionally relied on DNA extracted from whole leaves. To investigate the microbial communities on the adaxial (upper) and abaxial (lower) leaf surfaces, swabs were collected from both surfaces of two garden plants, Rhapis excelsa and Cordyline fruticosa. Samples were collected at noon and midnight and at five different locations to investigate if the phyllosphere microbial communities change with time and location. The abaxial surface of Rhapis excelsa and Cordyline fruticosa had fewer bacteria in contrast to its adaxial counterpart. This observation was consistent between noon and midnight and across five different locations. Our co-occurrence network analysis further showed that bacteria were found almost exclusively on the adaxial surface while only a small group of leaf blotch fungi thrived on the abaxial surface. There are higher densities of stomata on the abaxial surface and these openings are vulnerable ports of entry into the plant host. While one might argue about the settling of dust particles and microorganisms on the adaxial surface, we detected differences in reactive chemical activities and microstructures between the adaxial and abaxial surfaces. Our results further suggest that both plant species deploy different defence strategies to deter invading pathogens on the abaxial surface. We hypothesize that chemical and mechanical defence strategies evolved independently for harnessing and controlling phyllosphere microbiomes. Our findings have also advanced our understanding that the abaxial leaf surface is distinct from the adaxial surface and that the reduced microbial diversity is likely a consequence of plant-microbe interactions.

This retrospective observational study aimed to gain a better understanding of the protective duration of prior SARS-CoV-2 infection against reinfection. The objectives were two-fold: to assess the durability of immunity to SARS-CoV-2 reinfection among initially unvaccinated individuals with previous SARS-CoV-2 infection, and to evaluate the crude SARS-CoV-2 reinfection rate and associated risk factors. During the pandemic era time period from February 29, 2020, through April 30, 2021, 144,678,382 individuals with SARS-CoV-2 molecular diagnostic or antibody test results were studied. Rates of reinfection among index-positive individuals were compared to rates of infection among index-negative individuals. Factors associated with reinfection were evaluated using multivariable logistic regression. For both objectives, the outcome was a subsequent positive molecular diagnostic test result. Consistent with prior findings, the risk of reinfection among index-positive individuals was 87% lower than the risk of infection among index-negative individuals. The duration of protection against reinfection was stable over the median 5 months and up to 1-year follow-up interval. Factors associated with an increased reinfection risk included older age, comorbid immunologic conditions, and living in congregate care settings; healthcare workers had a decreased reinfection risk. This large US population-based study suggests that infection induced immunity is durable for variants circulating pre-Delta predominance.
A hybrid security system for drones based on ICMetric technology
Authors: Alheeti Khattab M. Ali , Khaled Alarfaj Fawaz , Alreshoodi Mohammed , Almusallam Naif , Al Dosary Duaa
Published: March 2023

Recently, the number of drones has increased, and drones’ illegal and malicious use has become prevalent. The dangerous and wasteful effects are substantial, and the probability of attacks is very high. Therefore, an anomaly detection and protection system are needed. This paper aims to design and implement an intelligent anomaly detection system for the security of unmanned aerial vehicles (UAVs)/drones. The proposed system is heavily based on utilizing ICMetric technology to exploit low-level device features for detection. This technology extracts the accelerometer and gyroscope sensors’ bias to create a unique number known as the ICMetric number. Hence, ICMetric numbers represent additional features integrated into the dataset used to detect drones. This study performs the classification using a deep neural network (DNN). The experimental results prove that the proposed system achieves high levels of detection and performance metrics.

Published: March 2023

Background

One of the longest-standing treatments to prevent delayed cerebral infarction (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH) remains raising the blood pressure to a certain level of mean arterial pressure. This may require high doses of norepinephrine, which has been associated with severe end organ damage. With this study, we aimed to investigate the effects of norepinephrine on the incidence of DCI in a clinical setting.

Methods

We conducted a retrospective evaluation of patients with aSAH admitted to our institution between November 2018 and March 2021. Potential risk factors for DCI were analyzed and significant predictors were assessed by means of a logistic regression analysis to account for potential confounders.

Results

In this study, 104 patients were included. Hereof, 39 (38%) showed radiologic signs of DCI between day three and 14 post-intervention. These patients had more frequent vasospasms (n = 37 vs. 30, p = 0.022), a higher Hunt & Hess score (3 ± 2 vs. 2 ± 1, p = 0.004), a lower initial Glasgow Coma Scale score (9 ± 5 vs. 12 ± 4, p = 0.003) and received a higher median norepinephrine dose (20,356μg vs. 6,508μg, p < 0.001). A logistic regression analysis revealed that only high-dose norepinephrine administration (OR 2.84, CI 1.56–7.8) and vasospasm (OR 3.07, CI 1.2–7.84) appeared to be significant independent risk factors for DCI.

Conclusion

Our results indicate a significant association between higher dose norepinephrine administration and the occurrence of DCI. Future research including greater sample sizes and a prospective setting will be necessary to further investigate the relationship.
Media ecology and change communication: Similarities, differences and opportunities for real-world synergies
Authors: Cheyunski Fred
Published: March 2023

A Media Ecology/Formal Cause Communication Model appears to have parallels with strategic/change communication offering means of exploring different but related areas of study and practice. Particularly, change communication continues to be critical in technology adoption whereas media ecology concerns ‘confronting technopoly’ and countering the surrender of culture to technology. A ‘change curve’, has had its own origins and part in the change communication process. However, media ecology’s particular communication focus appears based on maintaining human values in the face of such change. This article attends to the elements of change communication and technopoly confrontation through a review of related references. It discusses learning found in comparing strengths and opportunities. It suggests combining/reinterpreting pertinent processes for pursuing real-world synergies. Finally, the article proposes ‘remediating media’ process use proceeding in the aftermath of COVID-19 and international conflict.
Tupi or not Tupi, that is the question of the media: Contributions of Amerindian thought for a media ecology research agenda
Authors: Michelis Marina
Published: March 2023

This article discusses how the communicative ecologies and aesthetic interventions shared by Indigenous peoples through digital media add new perspectives to the study of media ecology. The aim is to think of ways to develop a research agenda that understands the key interactive levels that make up this communicative ecology in its complexity, in order to avoid the critical closures regarding the use of technologies and the political thinking about technique. As a starting point for this discussion, we will make connections between Brazilian cultural aesthetics, Indigenous ethnology and media studies.
From ‘Ouvert Oeuvre: Openings’
Authors: Karasick Adeena , Lehrer Warren
Published: March 2023

Inscribing what Levinas might call ‘espace vital’ (the space we can survive), ‘Ouvert Oeuvre: Openings’, (written/composed by Adeena Karasick and visualized/designed by Warren Lehrer), is an ecstatically wrought, never quite post-COVID-19 celebration/exploration of openings. It tracks the pain of openings read through socio-economic, geographic and bodily space. Employing fragmentation, layered language and sonic wordplay, these excerpts explore a range of intralingual etymologies of the word ‘opening’, laced with post-consumerist ironic and erotic language, theoretical discourse, philosophical and Kabbalistic aphorisms, ‘Ouvert Oeuvre: Openings’ foregrounds language as a material, physical organism of hope – highlighting the concept of opening as an ever-swirling palimpsest of spectral voices, textures, whispers and codes transporting us through passion, politics and pleasure as we negotiate loss and light. The full volume is forthcoming from Lavender Ink Press, Spring 2023.

Authors: Perez-Arbulu Jon
Published: March 2023

Gaur egungo eta etorkizuneko teknologien garapenean giltzarri dira material magnetikoak. NdFeB imanak trantsizio energetikorako material garrantzitsuak dira, sorgailu eta motor elektrikoetan erabiltzen dira eta. Tresna elektroniko askok ere, ordenagailuak edo smartphoneak adibidez, NdFeB imanak dituzte barnean. Kritikoak diren elementu kimikoak dituzten arren, lur arraroak kasu, material hauek dira gaur egun merkatu handiena duten imanak, energi produktu altuena ere baitute. Iman hauetako gehienak hauts-metalurgia bidez ekoizten dira, fase likido bitarteko sinterizazioa erabiliz. Prozesu honetan banda-galdaketa, ehoketa, orientazioa, sinterizazioa eta suberaketa dira eman beharreko pausoak puntako materialak lortzeko. Materialon bereizgarriak dira ale tamaina fina, oxigeno maila oso baxua, partikulen orientazio egokia eta mikroegitura homogeneoa.

Published: March 2023

Arku elektrikoa etengailuetan gertatzen den efektua da. Etengailuaren kontaktuak bata bestetik aldentzen direnean, etengailutik pasatzen den korronte elektrikoa kontaktuetatik etengailuaren gas isolatzailera pasatzen da, eta hau ionizatuz, bertan arku elektrikoa sortzen da. Arku elektrikoak efektu ez-desiragarriak sor ditzake etengailuetan; beraz, efektu horiek murrizteko asmoz, lan honen helburu nagusia hidrogenoaren baliagarritasuna aztertzea da etengailuaren gas isolatzaile modura. Horretarako, Navier-Stokesen ekuazioak eta Bolumen Finituen Metodoa (ingelesez, Finite Volume Method, FVM) oinarritzat hartuz, simulazio Magnetohidrodinamikoak (ingelesez, Magnetohydrodynamics, MHD) definitu dira ANSYS CFX programaren bitartez. Hala, arku elektrikoaren prozesuan oinarrizkoak diren aldagaiak kalkulatu dira, hala nola, tentsioa, tenperatura eta presioa. Emaitza horiek airea isolatzaile modura darabilten etengailuetan lortutakoekin alderatuz, hidrogenoa simulatutako aplikaziorako gas egokia den ala ez ondorioztatuko da.
Euskal haur eta gazteen biodibertsitate-alfabetatzea: kezka iturri bat
Authors: Barrutia Oihana , Pedrera Oier , Díez José Ramón
Published: March 2023

Larrialdi klimatikoarekin batera, biodibertsitatearen galera da gaur egungo krisialdi globalaren adierazle kezkagarrienetariko bat. Horri aurre egiteko, giltzarri dira biodibertsitatearekiko jarrera eta harekin erlazionatutako ezagutza. Izan ere, nekez kontserbatuko da ezagutzen ez dena. Gaur egungo haur eta gazteek, etorkizuneko helduek, alegia, hartu beharko dituzte erabakiak larrialdi honen inguruan. Hala, beharrezkoa da gazte hauen biodibertsitate-ezagutza ikertzea hezkuntza-estrategia egokiak diseinatu ahal izateko. Lan honetan, gaur egungo Hego Euskal Herriko haur eta gazteen (11/12-16/17 urte-bitartea) espezie-alfabetatze maila diagnostikatzen duten ikerketen emaitzak aztertu dira. Zehazki, ikasleek espezieez duten «ezagutza zabala» (identifikazioa eta izendapena) aztertzen duten lanak arakatu dira. Lanok iradokitzen dutenez, oso apala da etorkizuneko belaunaldiek bertoko espezieez duten ezagutza, eta hedatuta dago haien artean landareekiko itsutasuna. Bestalde, animalia karismatiko eta etxekotutako landareetarako isuria dute, eta animalien artean ugaztunak dituzte ezagunenak, alde batera utzita animalia talde mehatxatuenak (anfibioak, esaterako) edo bioaniztasun handikoak (ornogabeak, oro har). Landareen kasuan, loredunen ugaritasun eta erakargarritasuna dela-eta, haiek dituzte batez ere gogoan, gramineoak ahaztuta. Emaitzek agerian uzten dute, era berean, haur eta gazteen bizilekua zenbat eta txikiagoa edo landatarragoa izan, espezie autoktono gehiago identifikatu eta aipatzen dituztela. Ondorioz, argi azaleratu da biodibertsitatearen hezkuntza halabeharrez naturarekin harremanetan eta zientzia-praktikak erabiliz irakastearen beharra, irakasleen formakuntza gako delarik bide horretan.

Orden público durante la primavera de 1936 en la provincia de Murcia
Authors: Rabal García Jose Luis
Published: March 2023

La inestabilidad de la primavera de 1936 es una cuestión histórica que sigue suscitando interés, ya que se vincula con el origen de la Guerra Civil. Debemos analizar cuantitativa y cualitativamente la violencia y el orden público en la provincia de Murcia durante este período con el fin de comprender su dinámica, sus autores y consecuencias. Se han estudiado las fuentes históricas, destacando los documentos de archivo y la bibliografía, contrastándolas para que su estudio en conjunto supla las carencias individuales. Como conclusión, los desórdenes murcianos fueron de una intensidad similar a la de la situación general en España, la responsabilidad de la violencia se repartió equitativamente entre las organizaciones izquierdistas y derechistas y las autoridades no se caracterizaron en general por su pasividad, con algunas excepciones poco claras.

A hub-and-spoke model of geometric concepts
Authors: Valente Mario B.
Published: March 2023

The cognitive basis of geometry is still poorly understood, even the ‘simpler’ issue of what kind of representation of geometric objects we have. In this work, we set forward a tentative model of the neural representation of geometric objects for the case of the pure geometry of Euclid. To arrive at a coherent model, we found it necessary to consider earlier forms of geometry. We start by developing models of the neural representation of the geometric figures of ancient Greek practical geometry. Then, we propose a related model for the earliest form of pure geometry – that of Hippocrates of Chios. Finally, we develop the model of the neural representation of the geometric objects of Euclidean geometry. The models are based on the hub-and-spoke theory. In our view, the existence of specific models opens the possibility of addressing the relationship between geometric figures and geometric objects, in a novel way, in terms of their neural representation.

Del análisis realizado podemos concluir que estos programas favorecen la empleabilidad del colectivo, bajo un modelo integral de intervención que trasciende a la intermediación, abarcando acciones planificadas desde la formación para el empleo hasta el acceso a la vivienda. Se observa, además, su consolidación dentro de la estrategia de atención a la discapacidad en este territorio y su orientación hacia el logro de un nuevo modelo de centros de día, orientados a la capacitación profesional de las personas con discapacidad intelectual, con el objetivo de lograr un nuevo rol social que contribuya a su proyecto de vida.
Growth-stimulating and antioxidant effects of vanillic acid on healthy broiler chickens
Authors: Duskaev Galimzhan , Kurilkina Marina , Zavyalov Oleg
Published: March 2023

Background and Aim: Phytobiotics are a safe alternative to feed antibiotics in industrial poultry farming that increases productivity by stimulating various digestive enzymes to reduce the number of pathogenic microorganisms in the intestines and improve antioxidant status and immune response. This study aimed to evaluate the effect of vanillic acid in its pure form and in combination with gamma lactone on weight growth and the physiological parameters of broiler chickens.

Materials and Methods: The studies were performed on 120 Arbor Acres broiler chickens (7 days old) that were randomly divided into four groups with five replicates (cages) and six birds per replicate. The control group was fed the basal diet (BD) only. Group I was fed the BD + gamma lactone (average dose 0.07 mL/animal/day). Group II was fed the BD + vanillic acid (average dose 0.07 mL/animal/day). Group III was fed the BD + gamma lactone + vanillic acid in a 1:1 ratio (average dose 0.07 mL/body/day). Live weight of broiler chickens for all group was assessed at the end of each period (age of 7, 14, 21, 28, 35, 42 days). At the end of the experiment (on day 42), 10 broilers with an average live weight were selected for blood sampling from the axillary vein.

Results: The results showed a growth-promoting effect of vanillic acid when fed with a diet free of synthetic antioxidants. Groups I and II had increased live weights throughout the entire experiment and a significant increase at the end of the experiment (8.2%–8.5%; p ≤ 0.05) compared to the control group. Toxic effects were not found in the biochemical blood serum analyses of Groups II and III. The metabolic processes in the experimental groups were intensified, especially in the enzyme associated with amino acid metabolism (gamma-glutamyl transferase) in Groups I and III (p ≤ 0.05). Vanillic acid, whether fed alone or in combination with gamma lactone, exhibited high antioxidant activities, protected cells from oxidative damage by inducing total antioxidant, catalase, and superoxide dismutase activities (p ≤ 0.05), and reduced the level of malondialdehyde (p ≤ 0.05) measured. No significant changes in the morphological blood parameters were found.

Conclusion: The use of vanillic acid alone and in combination with gamma lactone increases the digestive enzyme activities in blood plasma, increases body weight, and has a positive effect on lipid metabolism and the antioxidant status of broiler chickens. These findings indicate the significant potential use of vanillic acid and gamma lactone in poultry due to their antioxidant properties.

Keywords: antioxidant status, Arbor Acres cross, blood, broiler chickens, feeding, gamma lactone, productivity, vanillic acid.
Effects of the selection process on malondialdehyde, catalase, superoxide dismutase levels, and the performance of gilts under tropical environmental conditions
Authors: Okafor Prester Chuka John , Homwong Nitipong
Published: March 2023

Background and Aim: Gilt selection has the propensity to improve reproductive performance and promote longevity. However, the impact of this process on oxidative stress biomarker levels remains to be unraveled under tropical conditions. This study aimed to determine the effect of management processes during gilt selection on serum malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD) levels, and the performance of replacement gilts under tropical environmental conditions. Materials and Methods: Two groups of 90 crossbred gilts (mean age: 9.72 ± 0.097 weeks) were selected 2 weeks apart, allotted to six pens of 30, and raised in an open barn with shaded roofs. Following their respective entry weeks, gilts in groups one and two were subjected separately to three subsequent selection processes (involving movements, handling, and examination of structural and reproductive traits) at weeks 12, 17, and 24 in the replacement barn. Grower, finisher, and gestation diets were supplied ad libitum for 25 weeks. Environmental temperature (°C), humidity (%), and light (lux) were recorded. Malondialdehyde, CAT, and SOD levels were assayed using blood samples collected on day 1 of experiment (PRE), and at week 24 in replacement barn (POST). Results: Feed intake, weight gain, and percent selected at week 24 were 1.89 versus 1.90 kg/day, 0.81 versus 0.76 kg/day, and 75.23% versus 64.45% for groups one and two, respectively. Sickness, death, slow growth, leg, and reproductive problems caused 24.76% versus 35.55% of removals in groups one and two, respectively. Serum biomarkers were insignificant at PRE but were elevated at POST, with mean values of 14.25 versus 13.84 uM, 5.10 versus 3.26 nmol/min/mL, and p < 0.05, and 1.13 versus 1.68 U/mL and p < 0.05 for MDA, CAT, and SOD in groups one and two, respectively. Conclusion: The impact of the selection process was meager compared to the adverse effect of high environmental temperatures. The management and selection of replacement gilts in an uncontrolled environmental temperature increase the risk of oxidative stress, especially in tropical regions. Keywords: antioxidant, gilt, oxidative, stress, tropical.

Authors: Mokhtar Zulaikha
Published: March 2023

The river is a highly dynamic environment and active ecosystem, human and industrial activity on its banks have an impact on it. Hence, continuous monitoring of industrial wastewater discharges is necessary to ensure environmentally sound waterways. Industries in Malaysia are increasing, and the number of polluted and slightly polluted rivers is also alarming. This brings up the main goal of this article, which is to describe the concept and categorisation considering the urgent need to improve Malaysia's river water quality and the industrial sectors role as a contributor to river pollution. The structure of this paper represents the argument on the essential issues of the field of study which is river pollution and compliance of industries with the focus area on Industrial Effluent Regulation 2009 (IER 2009) being observed. The purpose of this review is to provide better understanding to readers on the various concepts of rating parameters in measuring environmental compliances with industrial effluent discharges. The main idea in mind is to identify the themes in measuring compliances discussed in literatures and concludes with discussion on how the proposed compliance rating parameters should be selected with regards of research finding and documents review. The literature research identified four topics related to compliance of industrial effluent discharge: regulatory standard, policy, testing/laboratory requirements, and consent requirement. Plant operation, community empowerment, environmental risk and emergency planning, regulatory and environmental audit are rating criteria that are frequently covered in the papers that are being used to monitor compliance.
Development of a Smart Mental Health Support System
Authors: Hassan Nazmul
Published: March 2023

We know that many people suffer from depression, anxiety, stress, hypertension, and many more mental illnesses in this pandemic situation. As a result, the condition of their mental health is getting bad to worse. However, very few of them can consult a psychiatrist, therapist, or professional who'll guide them properly to get rid of their problems. Keeping that in mind, we came up with an idea to build an intelligent web app that will help people suffering from mental health but not consult a doctor/psychiatrist. This system allows professionals to check and follow up on their patients from remote areas. Both patients and professionals can communicate through audio, video, voice, and text messages. Users, as a patient, can also directly search for professional psychiatrists/ doctors or consultants and request appointments through the app to get guidelines. Professionals can check patients' history, review appointments, accept them, schedule them, and provide guidelines for improvement. Patients will also have the facility to get a quick in-app therapy to improve their mindset if they feel they're not okay, which includes breathing exercise, some cardio exercise, a short audio clip on a motivational story, and a feature that will allow expressing user's hidden thoughts or some words they can share with our live chat agent. This system can play a significant role in the life of the people who are introverts, shy from sharing their mental health issues, and the people who don't have the opportunity to consult a mental health professional from their position directly. The overall system has been tested in a lab environment to ensure the best user experience, including a very user-friendly interface. It shows more efficiency in its service to help people countrywide who are suffering from mental illness.
Factors affecting Covid-19-Associated Cardiovascular Morbidity and Mortality In Older Adults
Authors: Moyambo Zack

Serious intense respiratory disorder coronavirus 2 (SARS-CoV-2) taints have cells taking after authoritative with the cell surface ACE2 receptors, subsequently driving to coronavirus illness 2019 (COVID-19). SARS-CoV-2 causes viral pneumonia with extra extrapulmonary appearances and major complications, counting intense myocardial harm, arrhythmia, and stun primarily in elderly patients. Besides, patients with existing cardiovascular comorbidities, such as hypertension and coronary heart malady, have a more regrettable clinical result taking after compression of the viral sickness. A striking include of COVID-19 pandemics is the tall rate of fatalities in progressed matured patients: this could be due to the predominance of slightness and cardiovascular illness increment with age due to endothelial brokenness and misfortune of endogenous cardioprotective components. ​​In spite of the fact that exploratory prove on this point is still at its earliest stages, the point of this position paper is to hypothesize and talk about more suggestive cellular and atomic instruments whereby SARS-CoV-2 may lead to hindering results to the cardiovascular framework. We are going center on maturing, cytokine storm, NLRP3/inflammasome, hypoxemia, and discuss contamination, which is an rising cardiovascular hazard calculate associated with rapid urbanization and globalization. We are going at last examine the affect of clinically accessible CV drugs on the clinical course of COVID-19 patients. Understanding the part played by SARS-CoV2 on the CV framework is in fact required to induce encourage experiences into COVID-19 pathogenesis and to plan a restorative methodology of cardio-protection for slight patients.
Classical Bivalent Logic as a Particular Case of Canonical Fuzzy Logic
Authors: Skliar Osvaldo , Gapper Sherry , Monge Ricardo E.
Published: March 2023

A review is presented of the correspondence existing in both classical bivalent logic (BL) and canonical fuzzy logic (CFL) between each law or tautology in propositional calculus and a law in set theory. The latter law consists of the equality of a) a set whose structure is isomorphic to the law considered in propositional calculus and b) the universal set. In addition to the operations of CFL considered previously by the authors, initial attention is given to the operations with infinite sets by considering two of them: the union of sets and the intersection of sets. Attention is also given to how propositional calculus in BL can be considered a particular case of propositional calculus in CFL, and how the theory of classical sets can be considered a particular case of the theory of fuzzy sets according to CFL.
Comparative study of state space averaging and PWM with extra element theorem techniques for complex cascaded DC-DC Buck converter
Authors: Shete Sangeeta , Joshi Prasad
Published: March 2023

Until now, most commonly used state space averaging and PWM techniques have been applied to different converter topologies and their advantages and disadvantages were stated. However, the superiority of an analytical technique was not justified based on a parametric comparison of these techniques for the same converter topology. Hence, in this paper, first time a comparative evaluation of two commonly used modelling techniques for fourth order converter is presented. The first approach makes use of a state-space averaging of the converter and is based on analytical manipulations using different state representations of the converter. The second approach is based on PWM switch modelling with an extra element theorem and consists of topological manipulations. The two modelling techniques are applied to the same complex cascaded DC-DC Buck converter and a transfer function is obtained. These techniques are compared for different features and the study concludes that state space modelling technique is systematic and less complicated than PWM switch modelling with an extra element theorem for a higher order converter.
3D CNN hand pose estimation with end-to-end hierarchical model and physical constraints from depth images
Authors: Xu Zhengze , Zhang Wenjun
Published: March 2023

Previous studies are mainly focused on the works that depth image is treated as flat image, and then depth data tends to be mapped as gray values during the convolution processing and features extraction. To address this issue, an approach of 3D CNN hand pose estimation with end-to-end hierarchical model and physical constraints is proposed. After reconstruction of 3D space structure of hand from depth image, 3D model is converted into voxel grid for further hand pose estimation by 3D CNN. The 3D CNN method makes improvements by embedding end-to-end hierarchical model and constraints algorithm into the networks, resulting to train at fast convergence rate and avoid unrealistic hand pose. According to the experimental results, it reaches 87.98% of mean accuracy and 8.82 mm of mean absolute error (MAE) for all 21 joints within 24 ms at the inference time, which consistently outperforms several well-known gesture recognition algorithms.
