Sensor fusion for 3D+T motion detection and target tracking

This paper addresses the problem of motion analysis performed from digital data captured by a network of motion sensors scattered over a field of interest where 3D+T motion analysis is per- formed. Motion analysis, as referred here for digital signals, proceeds through consecutive steps of detection, motion-oriented classification, parameter estimation and tracking. The scheme proposed in this paper is relevant to applications that can be found in medicine, earth science, surveillance and defense. The major challenges involved in the feasibility of this network are as follows: signal sampling from a sensor network, photodetection and optimal strategy for cope with energy harvesting and wireless communication capabilities. The motion sensors implement wireless communications to some gateway or data sink that relays the collected information to a remote central station. Motion sensors are assigned to catch motion with high sensitive sparsely distributed sensors and to build the trajectories. Other sensors can be added to the system for specific purpose like video camera. Video cameras are assigned to catch high resolution images or videos with densely and regularly distributed sensors to perform pattern classification and recognition. The central station implements the motion analysis algorithm. Motion analysis is performed as a dual control referring to both an accurate model based on theoretical mechanics and an adaptive learning system based on a supervised neural network. This paper describes the effective components of the system which are namely the sensor layer, the telecommunication layer, and the application layer.
Comparative Study of Mechanical and Electrical Characteristics of High-Strength and Conventional Electrical Steel for EV Traction High-Speed Multilayer IPMSM Using Rare-Earth Free PM

In this article, the electrical and mechanical characteristics of multilayer interior permanent magnet synchronous motors (ML-IPMSMs) using ferrite permanent magnets (PMs) are compared when driven at high speeds with respect to the type of electrical steel. In high-speed operation, the mechanical and electrical characteristics of ML-IPMSMs vary depending on the number of PM layers, PM shape, number of bridges, and bridge thickness. In addition, ferrite PMs have a lower coercive force than neodymium (Nd) PMs; therefore, irreversible demagnetization (ID) must be considered, and it is affected by the number of PM layers and PM shape of ML-IPMSMs. Thus, when designing a multilayer IPMSM using ferrite PMs for electric vehicle (EV) traction, all characteristics should be considered. Compared to conventional electrical steel (CES), high-strength electrical steel (HSES) offers advantages in mechanical properties, allowing for greater flexibility in ML shape. Consequently, it is possible to design a shape with improved electrical performance when compared to CES by adjusting the ML shape. In this article, all characteristics of each ML-IPMSM using HSES and CES are reviewed via finite element analysis (FEA), and the benefits of HSES-applied motors for high-speed driving motors are presented. To verify the validity of the review content in this article, experiments are conducted on the manufactured motor, and FEA results are compared with the test results.
Reproductive and sexual health concerns
in HIV-positive youth, aged 15 to 24 years

Introduction: Recognition of reproductive and sexual needs of HIV-positive youth provides health planners and policy-makers with required information to take practical measures in addressing this challenge. Therefore, this study targeted at explaining the reproductive and sexual health concerns of HIV-positive youth. Material and methods: The present descriptive qualitative study was performed using content analysis approach. To collect data, in-depth semi-structured personal interviews were conducted in a calm and private environment. As a result, 19 interviews were done among 17 HIV-positive young people, aged 15 to 24 years (11 girls and 6 boys). Data were analyzed using MAXQDA software, version 12. Results: Followed by analyzing the content of interviews, focusing on the reproductive-sexual health concerns of HIV-positive youth, five categories and 16 sub-categories were obtained. Categories included mental disorders, social exclusion, sexual problems, physical problems, and lack of optimal health services. Conclusions: Patients’ psychological, physical, and sexual problems, along with incomplete awareness of their reproductive and sexual issues, can cause irreparable personal and social health consequences. In this manner, the reproductive and sexual needs of young people should be considered, and more practical interventions are required in this field
Positive dependence of thermal conductivity on temperature in GeTe/Bi2Te3 superlattices: the contribution of electronic and particle wave lattice thermal conductivity

Temperature-dependent thermal conductivity of phase-change material, GeTe/Bi2Te3 superlattices, has been investigated in the temperature range of 40–300 K. We have found that thermal conductivity increases with increasing temperature, which is contrary to the common results indicated by other works. In this paper, two possible mechanisms are suggested for this result. One is that the thermal conductivity is affected by the thermal boundary resistance at the interfaces between layers, and the other considers the factor of electronic thermal conductivity in the partially coherent regime which is based on the very wave-particle duality of phonons. Finally, the periodic thickness dependence of the thermal conductivity in GeTe/Bi2Te3 superlattices have been measured at room temperature, and the results indicate the main contribution of electron in the total thermal conductivity and the partially coherent regime of phonon. Thus we believe that the second explanation is more reasonable. The work here deepens the understanding of basic mechanisms of thermal transport in phase-change superlattices, and is instructive in modeling and simulation of phase change memories.
Analysis of Cytotoxic and Antitumor Potential of Passiflora quadrangularis

ABSTRACT The cytotoxicity of ethanolic extract of Passiflora quadrangularis (PQ) leaves was analyzed on cancer cell lines by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Antitumor effect was analyzed on mouse solid and ascites tumor models. The phytochemical profile of the extract was analyzed by liquid chromatography-mass spectrometry (LC-MS). Apoptosis and cell cycle were analyzed by fluorescence resonance energy transfer (FRET) and flow cytometry. PQ exhibited cytotoxicity on Dalton’s lymphoma ascites (DLA) and Ehrlich’s ascites carcinoma cells with IC50 of 9.4 and 9.2 μg mL−1 and anti-proliferative effect on breast (MCF7) and colorectal (HCT116) cancer cell lines with IC50 of 166.5 and 107.09 μg mL−1, respectively. The extract did not show toxicity in normal rat intestinal cells IEC6 and murine macrophage cells RAW264.7. In ascites tumor model, the mean survival days of the animals increased to 25 ± 4.30 d in the treated group compared to untreated (21.2 ± 2.68 d). In DLA-induced solid model, the tumor weight decreased to 1.6 ± 0.9 g from 4.5 ± 0.58 g by treatment with 400 mg kg−1 b.w. extract. LC-MS analysis revealed the presence of genistein, kaempferol, isovitexin, and quercetin that are known for anticancer potential. The acute toxicity in mice revealed that PQ is nontoxic. FRET and flow cytometry analysis indicated an induction of apoptosis in PQ-treated cells
Forests of Fear: Illegal Logging, Criminalization, and Violence in the Carpathian Mountains

In this article we explore the twisted consequences of the worldwide turn toward prohibitive policies and criminalization in conservation. We argue that tackling environmental challenges with legal repertoires that are coercive and punitive in nature increases criminalization and produces insidious and overt forms of violence. Tough-on-crime measures aimed at curbing illegal logging advance social vulnerabilities, further marginalizing already disenfranchised rural populations. Also, such measures trigger the formation of a culture of patronage, secrecy, fear, and anger, which facilitates the rise of forest violence. Transformations of forest use under increasingly harsh regimes of conservation have been documented worldwide, but these processes in Eastern Europe have received far less scholarly attention. Here we explore forest criminalization in Romania after it became a member state of the European Union, looking at different groups of alleged wrongdoers: petty community users, local forestry businessmen, and forestry officers. Drawing on interviews with forestry and conservation actors, media analysis, and ethnographic research of communities for which illegal logging was an everyday reality, we show how criminalization escalated into insidious forms of violence and the deepening of rural vulnerabilities.
Benefits of early transplantation in patients with chronic renal failure undergoing coronary revascularization

Objective: This study aimed to evaluate the effectiveness of post-revascularization surgery in reducing future cardiac events among kidney transplant candidates. Additionally, the role of non-invasive diagnostic techniques and the use of coronary angiography in determining the prognosis of patients scheduled for kidney transplantation were examined. Material and Methods: A retrospective analysis was conducted on 202 renal transplant recipients who underwent their first coronary revascularization procedure after initiating renal replacement therapy between January 2021 and December 2021. Demographic data collected included patient age, sex, race, duration of prior end-stage renal disease, and primary renal diagnosis. Results: The study population consisted of 120 men and 82 women, with a mean age of 56.9 years. Diabetes mellitus (DM) and hypertension (HT) were present in 58.4% and 89.6% of the patients, respectively. Coronary angiography was performed in 30% of patients considered at risk. The median graft rejection time was 145 days according to Kaplan-Meier analysis. Discussion: Coronary artery disease (CAD) has a significant negative impact on the pre-, intra-, and post-transplant survival of patients with chronic kidney disease. Myocardial revascularization is recommended in selected patients with unstable cardiac symptoms or chronic kidney disease, providing long-term survival benefits. Collaborative decision-making between cardiologists and nephrologists is crucial to provide optimal care for this high-risk patient population. Lifestyle modifications, risk factor control, and careful patient selection for myocardial revascularization are key in managing coronary artery disease in chronic kidney disease patients. Conclusion: Managing coronary artery disease in chronic kidney disease patients, especially those who are candidates for kidney transplantation, requires a comprehensive approach. Optimal treatment strategies should consider the intricate relationship between cardiovascular and renal factors. Collaborative care involving cardiologists, nephrologists, and transplant specialists, as well as a focus on both myocardial revascularization and medical therapy, can lead to improved outcomes. Further research is needed to refine treatment guidelines and strategies for this high-risk patient population.
Robust semiglobal swarm tracking of coupled harmonic oscillators with input saturation and external disturbance

The robust semiglobal swarm tracking problem of N coupled harmonic oscillators and 1 actual leader with input saturation and external disturbance on a directed communication topology is considered, in which the N coupled harmonic oscillators are referred to followers. First, the low‐and‐high gain feedback technique is introduced to construct a relative state‐dependent control algorithm. Then, an observer‐based control algorithm is designed based on the low‐and‐high gain feedback technique and the high‐gain observer design methodology. Sufficient conditions are derived to guarantee robust semiglobal swarm tracking for state‐feedback control and output‐feedback control, respectively. Numerical simulations are finally provided to verify the theoretic results.
Content frequency and shape features based on CBIR: application to colour images

Due to the diversity of the image content, we propose in this study a new technique for content-based image retrieval to characterise the image. In this scenario, all images are characterised by their frequency content and their shape information. Indeed, using the high-resolution spectral analysis methods, especially the 2-D estimation of signal parameters via rotational invariance techniques, we extract from the image its content frequency and with the angular radial transform its shape information to construct a new vector descriptor. The experimental results applied to the Coil_100 database show the effectiveness and the robustness of our approach compared with the method based on the shame information only, and the precision average can be reached as 74.49%.

Bu çalışmada, başlangıç seviyesi keman eğitiminde kullanmak amacıyla keman öğrenenlere çalma performanslarıyla ilgili bir geri dönüt sağlayacak karmaşık spektral fark yöntemi tabanlı bir otomatik müzik transkripsiyon sistemi önerilmiştir. Ayrıca, önerilen müzik transkripsiyon sistemine dayalı ve kemandaki temel etütlerden olan dört boş tel, sol majör arpej ve sol majör dizi notalarını tespit eden Matlab yazılım tabanlı bir kullanıcı arayüzü gerçekleştirilmiştir. Önerilen sistemin performans analizi için iPad tablet tabanlı profesyonel kayıt sistemi kullanarak sekiz katılımcıdan elde edilmiş bir ses kayıt veri seti oluşturulmuştur. Önerilen sistemin keman ses kayıtlarının analizini doğru yapabilmesi için müzik parçasının kendisini oluşturan notalara uygun bölütlenmesi, bunun için de notaların başlangıç zamanının doğru bir şekilde tespit edilmesi gerekmektedir. Piyano ve gitar gibi diğer müzik çalgı seslerine kıyasla, keman sesinin nota başlangıç zamanı tespiti, sahip olduğu zarf karakteristiği nedeniyle daha zordur. Önerilen çalışmada nota başlangıç zamanı tespiti için karmaşık spektral fark yöntemi kullanılmaktadır. Daha sonra, çıkarılan bölüte hızlı Fourier dönüşümü uygulanarak keman sesinin notası ve oktavı belirlenecek şekilde bölütün temel frekansı bulunmaktadır. Ayrıca, geliştirilen arayüz üzerinde süre ve gürlük analizleri de yapılabilmektedir. Kıyaslamalı sonuçlar, önerilen sistemin önemli müzik analiz yazılımları olan MIRtoolbox ve Essentia’daki yöntemlere göre daha başarılı performans sergilediğini göstermektedir.
Improving the accuracy of identifying the lognormal curve in the Johnson system

Abstract Multiple estimation methods provide discriminants to determine curves in the Johnson (1949) system, but few studies have been conducted to explore their accuracy. In this study, a simulation study was implemented to determine whether three discriminants can discriminate the types of Johnson curves correctly. The results show these discriminants failed to identify the lognormal curve in the system. The receiver operating characteristic curves and the Youden index (Youden 1950) were used to find the optimal cutoff points for these discriminants to identify the lognormal curve more precisely. A new discriminant was also proposed for the moment method (Johnson 1949) in this study.
On the different models describing the equilibrium shape of an erythrocyte

As one of the most important types of blood cells in all vertebrate, the study of the equilibrium shape of erythrocytes is of great importance for the understanding of physicochemical and mechanical properties. The present paper is a summary of the existing models and methods to describe the shape of a red blood cell. Starting with the simplest known model – the one based on the Cassini ovals and finishing with the general shape equation for axisymmetric fluid membranes, we compare each model with a set of experimental data. The aim is to classify the models and give suggestions when and for what purpose they can be used, as for example in analytical studies of interactions between the erythrocytes, diagnostics based on shape distribution, experimental study through light scattering etc.
Integrating Life Skills Learning and Teaching Support Materials into Teachers’ Teaching Strategies

This paper investigated the integration of Learning and Teaching Support Materials (LTSM) into teachers’ teaching strategies to mediate teaching and learning in Life Skills Grade 3 Foundation Phase classrooms. The aim was to understand teachers’ teaching strategies integrating LTSMs to mediate teaching and learning. The South African National Policy Guidelines for LTSMs require teachers to be mediators of teaching to improve the quality of results. This paper was informed by Engestrom’s Cultural Historical Activity Theory, whose strength lies in its ability to enable researchers to understand learning as the complex result of tool-mediated interactions. The study used a qualitative methodology with an interpretive perspective. In order to gather and analyse data, semi-structured interviews, structured observation, and documents were used. Three Life Skills teachers were chosen using a purposeful sample process, and they were interviewed and observed in action. Themes that were formed from the subsidiary questions and coded for convenience referencing served as the guide for the data analysis under the guidance of content analysis. Findings revealed that teachers demonstrate a lack of learning and teaching support materials and a lack of professional development to integrate strategies during lesson presentations. The researchers concluded that there is an imperative need for Life Skills teachers to integrate LTSMs in their teaching strategies to guarantee access and support to the delivery of quality education. The authors recommend that the Department of Education should develop and equip Life Skills teachers to integrate LTSMs into their teaching strategies. Keywords: Learning and teaching support materials, Life Skills, Mediate, Teaching.

Artificial-Neural-Network-Based Autonomous Demand Response Controller for Thermostatically Controlled Loads

Thermostatically controlled loads (TCLs) possess an inherent potential for demand-side management (DSM). Space heating (SH) demands offer added flexibility due to their heat-storing capability and fast response times that may be unnoticed, but it has significant value for DSM. In this article, a communication-free demand response (DR) controller has been presented that harnesses the heat-storing capacity of residential buildings by utilizing TCLs. The proposed controller addresses customer voltage violations, comfort constraints, and energy savings. The DR controller attempts to control the TCLs by relying on voltage and voltage-to-load sensitivity. By deploying an artificial-neural-network-based model, the proposed control scheme ensures that the SH loads connected at spatially distributed nodes in the power system participate fairly to mitigate the residential grid voltage violations. Simulation results verify the proposed controller's performance to revamp the system voltage profiles while maintaining the desired comfort of end users. The controller is successfully tested with distributed generation integration, system reconfiguration, severe ambient temperature, and noise in the measured signals.
An expander system of high stable laser beam for cesium atomic fountain clocks

The preparation of cold atoms sample has a strict requirement for cooling lasers characteristics such as power stability, polarization, collimation, uniformity and verticality. This work implements a design of an expander system of high stable laser beam for the cold atom preparation. The cooling laser characteristics can be adjusted by the design, and the use of non-magnetic materials to avoid the magnetic field on the impact of cold atom. The cold atom sample with the number of 2×108 and temperature of 5μk was obtained by expander system. The result meets the requirements of the preparation of cold atoms for cesium atomic fountain clocks.
Effect analysis of land-use pattern with landscape metrics on an urban heat island

Abstract. In order to explore the effect of land uses on urban heat island (UHI), the correlation between land-use pattern and land surface temperature (LST) is quantitatively analyzed separately in the urban and suburban areas. In the case of the Changsha–Zhuzhou–Xiangtan city group of China, the LST is retrieved by the Landsat-5 TM image acquired on September 2009, and the land-use composition and configuration are described by five landscape metrics: the percentage of landscape, edge density, mean patch area, the mean Euclidean nearest-neighbor distance, and Shannon’s evenness index. Pearson’s correlation coefficients and an ordinary least squares multiple linear regression model are utilized to evaluate the correlation between each landscape metric and LST, respectively, and to select the optimal combination of landscape metrics to describe the LST at an optimal scale in the whole and the urban/suburban parts of the study area. According to the conclusions, it is suggested that, in order to restrain the aggravating UHI and its influence, all land uses should be reasonably distributed, and the proportion of critical land-use types should be optimized.
