Exploring an Affective and Responsive Virtual Environment to Improve Remote Learning
Authors: Qi Jianing , Tang Hao , Zhu Zhigang
Published: March 2023

Online classes are typically conducted by using video conferencing software such as Zoom, Microsoft Teams, and Google Meet. Research has identified drawbacks of online learning, such as “Zoom fatigue”, characterized by distractions and lack of engagement. This study presents the CUNY Affective and Responsive Virtual Environment (CARVE) Hub, a novel virtual reality hub that uses a facial emotion classification model to generate emojis for affective and informal responsive interaction in a 3D virtual classroom setting. A web-based machine learning model is employed for facial emotion classification, enabling students to communicate four basic emotions live through automated web camera capture in a virtual classroom without activating their cameras. The experiment is conducted in undergraduate classes on both Zoom and CARVE, and the results of a survey indicate that students have a positive perception of interactions in the proposed virtual classroom compared with Zoom. Correlations between automated emojis and interactions are also observed. This study discusses potential explanations for the improved interactions, including a decrease in pressure on students when they are not showing faces. In addition, video panels in traditional remote classrooms may be useful for communication but not for interaction. Students favor features in virtual reality, such as spatial audio and the ability to move around, with collaboration being identified as the most helpful feature.

Authors: Xie Hongyu , Liu Guangzhu , Chen Zelin , Xu Xintong , Wei Chong
Published: March 2023

This study aims to explore a preparation method based on a combination of melting and ultrasound to produce a Ga2O3/ZnO (GZ) spherical composite with a snake raspberry structure for the degradation of methyl orange at room temperature in dark. The catalyst exists in the form of a (GZ) composite and an anhydrous ethanol mixture after the ultrasonic treatment of premelted GaZn liquid metal alloy in anhydrous ethanol. The degradation activity of the catalyst was evaluated according to the amount of catalyst, alloy extraction temperature, acid–base environment, and inorganic salt ions. A transmission electron microscope (TEM) was used to confirm that the material was Ga2O3 coated with ZnO, with a structure similar to that of snakeberry. The electron paramagnetic resonance (EPR) and a series of free radical inhibition experiments demonstrated that ·O2− is produced during the ultrasonic preparation of the catalyst and plays an important role in the degradation process after adding MO. The removal rate of MO reached 99.75% at 3 min. Three possible degradation pathways were proposed based on the intermediates produced during the degradation process, which were identified by liquid chromatography–mass spectrometry (LC–MS). The results of this study may provide a new choice for the degradation of organic pollutants.

Published: March 2023

The rapid expansion of economic activities in Egypt’s Central Eastern Desert has resulted in poorly coordinated groundwater development, having a negative impact on the resource. This study was conducted to assess the hydrochemical characteristics of the different aquifers in the Central Eastern Desert, with an emphasis on the impact of seawater intrusion and groundwater quality for different purposes. A total of 21 groundwater samples were collected representing the three main aquifers (Eocene Carbonate, Nubian Sandstone, and Fractured Basement) in the Central Eastern Desert, and analyzed for major ions and trace elements. The majority of the samples had electrical conductivity values that exceeded the salinity limit for natural water. Groundwater saline load is primarily influenced by sodium, calcium, chloride, and sulfate concentrations. The groundwater in the Central Eastern Desert mainly consists of Na-Cl, Ca-Cl, and Na-SO4 water-types. Saltwater intrusion and water-rock interactions via cation exchange and minerals weathering are the primary controlling factors of groundwater hydrochemistry. The high salinity of this groundwater renders it unsuitable for irrigation or consumption. Additionally, it is unfit for domestic use based on total hardness values. Furthermore, the Al, Cd, Fe, Mn, and Ni concentrations in the investigated groundwater exceed the allowable limits for human consumption. Proper mitigation measures and adaptation strategies are required for groundwater sustainability in the Central Eastern Desert.

The heavy metals concentration in algae can be used as a bioindicator of the pollution of an ecosystem. In the present study, we determined the levels of the elements Fe, Pb, Cu, and Zn in chlorophyta of the species Cladophora, Spirogyra, Chara, and Zygnema. The samples were collected in February of 2021 in three different locations in Algeria (Dar El Chioukh lake, Oued Mellah, and Oued Boucedira). Our results showed that all four algae species accumulated high levels of heavy metals in surface water, with concentrations ranging from 3.14 to 5600 mg/kg. The Pb levels in all four species exceeded the recommended standard set by the International Atomic Energy Agency (IAEA) of 0.574 mg/kg, with the highest concentration of 50.85 mg/kg recorded in Cladophora at the first location. Similarly, Fe and Cu levels were found to be above the recommended standard, with maximum concentrations of 5600 mg/kg and 82.5 mg/kg, respectively. On the other hand, Zn levels were found to be lower than the standard of 128 mg/kg, with the highest concentration of 47.5 mg/kg recorded in Spirogyra at the third location. The results of the principal component analysis (PCA) confirmed that the heavy metal pollution of these waters was of anthropogenic origin, likely stemming from urban, industrial, and agricultural activities.

Published: March 2023

For the poor working conditions of tractors, single-motor drive tractors usually choose a motor with large parameters, which leads to the lower efficiency of the motor under low-load conditions. Taking a wheeled tractor of YTO as the research object, a driving scheme of a dual-motor electric tractor was proposed, and the main components of the tractor electric drive system were matched. Based on MATLAB/Simulink, the electric tractor drive system model was established. On the premise of meeting the dynamic needs of the tractor, an optimization model was established with the tractor power consumption as the optimization goal and the power distribution coefficient of dual motors as the decision variable. The optimization model was solved by a genetic algorithm. The driving characteristics of the optimized electric tractor and the original tractor, as well as the instantaneous power consumption and total power consumption of the tractor before and after optimization, are compared and analyzed. The results show that the traction efficiency of the optimized electric tractor is about 2.7% higher than that of the original tractor, and the total power consumption of the electric tractor before and after optimization is reduced by 8.2%. The power performance and economy of the tractor after parameter matching and optimization are significantly improved.

This article aims to find solutions for banking services in providing credit to Micro, Small and Medium Enterprises (MSMEs) in Indonesia which are focused on guarantees. The research method used is mixed methods or a combined method of quantitative and qualitative approaches, where both complement each other so that accurate data can be obtained. This article concludes that there are several internal policies from banks in providing credit either guaranteed or unsecured. The government and business actors are trying and jointly looking for a way out so that the country's economic condition remains stable. In the process, it was unexpected that the MSME sector was the only one that could survive even in a state of economic crisis. MSMEs are proven to make a positive contribution to the formation of the Gross Domestic Product (GDP) and also employment. With these facts, the Government through Financial Institutions such as Banking, cooperates in obtaining capital for MSME actors to develop their businesses through credit loans. The solution obtained for MSME actors is that banking institutions will provide credit loans with and or without collateral. For the security aspect for capital lending institutions in terms of unsecured loans, banking institutions will implement an insurance system that works with third parties, where there will be a premium at each stage of payment.

Published: March 2023

A popular investment that is in great demand among investors is stocked. Stocks are another type of financial instrument offering returns but carrying a higher risk level. Price time series are more difficult to manage than return time series. To equip investors with the knowledge to forecast future stock prices, mathematical models can be used to simulate stock price fluctuations. The time series method, especially the Integrated Moving Average (IMA) model, is a model that can be used to observe changes in stock prices. The Integrated Moving Average (IMA) model will be used in this study to simulate stock returns. The Integrated Moving Average (IMA) model is a Moving Average model that is carried out with a differencing process or an Autoregressive Integrated Moving Average model with a value of Autoregressive being zero. This study uses secondary data simulations from secondary sources, such as data on daily business stock prices for one year, to conduct a literature review and test experiments. The Integrated Moving Average (IMA) model is used in data processing, especially to test the differencing data process. The results obtained are the IMA (1,1) model with the following equation Zˆt = Zt-1 + 0, 5782at-1, which can be used to anticipate future stock returns. Based on these results, it is expected that investors can predict the value of shares within a certain period of time.

Near-ring is a generalization of ring. In ring theory, let R be a ring over addition and multiplication operation with unity element and G be a commutative group under addition operation. Then G together with scalar multiplication of R and holds several axioms called module over ring. Let N be a near-ring, here we can construct the module over near-ring called near-module. We have three definitions of module over near-ring, such that, near-module, modified near-module, and strong near-module. Then we showed that strong near-module can be constructed into strong near-module factor as well as module factor in G. Furthermore, we generalized the fundamental theorem of homomorphism in module over ring to strong near-module over strong near-ring.

Произведена оценка задержек в IP-ориентированных сетях общего доступа, представлена концептуальная мо­дель IP-ориентированной сети. Анализ задержек пакетов IPTD произведен на исследуемом участке сети как в восходящей, так и в нисходящей ветви аналитическими методами. Средняя задержка для систем массового обслуживания определена с помощью приближенной формулы Крамера/Лангенбаха-Бельца, при этом принято, что интервалы между поступлением заявок во входном потоке нисходящей ветви подчиняются классическому распределению Парето, а на восходящую ветвь действует пуассоновский поток. Имитационные модели нисходящей и восходящей ветвей для случая анализа сегмента GPON разработаны в среде имитационного моделирования GPSS World. В результате численных исследований аналитических мо­делей и обработки результатов имитационных моделей были получены семейства кривых зависимостей средней задержки и ее среднеквадратического отклонения от параметров распределений интервалов во входном потоке для всех исследуемых видов трафика и фаз обслуживания для рассматриваемого примера GPON.

Estimation of delays in IP-oriented public access networks was calculated, a conceptual model of an IP-oriented network is presented. Analysis of IPTD packet delays was carried out on the studied section of the network both in the ascending and descending branches by analytical methods. The average delay for the queuing systems is determined using the approximate Cramer/Langenbach-Beltz formula, it is assumed that the intervals between the arrival of requests in the input stream of the descending branch obey the classical Pareto distribution, and the Poisson flow acts on the ascending branch. Simulation models of the downstream and upstream branches for the case of GPON segment analysis were developed in the GPSS World simulation environment. As a result of numerical studies of analytical models and processing of the results of simulation models, families of curves of dependencies of the average delay and its standard deviation from the parameters of the distributions of intervals in the input stream for all types of traffic and service phases for the considered GPON example were obtained.

Authors: Badea Nicolae , Voncilă Ion , Codreanu Laurenţiu
Published: March 2023

The paper is dealing with modelling and simulation of running principle of shunt type active power filter. It is possible to highlight the running of the active filter as a result of correlation of power supply voltage, the power outage on filter coil and converter input voltage. The mathematical equations for filter running were implemented into the PSIM software, both with instantaneous variables without DC voltage control and Vdc voltage control in the (dq) coordinate system. The numerical simulations performed without DC voltage control have shown a Vdc voltage overgrown. Vdc voltage control is taking off this inconvenience and allows harmonics balance putting in a filter current in phase opposition with the harmonic current of nonlinear load. By numerical simulation of varable voltage power supply of the nonlinear customer it was highlighted existence of an optimal area of THDi thanks to correlation between grid voltage, coil and converter input voltage. Choosing and dimensioning of three phase coil of power circuit of SAPF has a decisive influence on the voltage range of adjustment of nonlinear customer and implicit on THDi grid current.
Features of Design of Medical Electronic Devices

Published: March 2023

The design features of medical electronic devices are considered. It is shown that the development of medical electronics is not an easy task and the designer must be prepared to face problems and regulations that are more strict than for household appliances, due to the fact that the failure of these devices to work properly can lead to tragic consequences, up to death. A number of difficulties that arise in the process of designing medical equipment is shown, which is presented in the form of a hierarchy of decisions. The main standards for designing devices of such type are given, among which there are IEC-60601-1-1 and IEC-60601-1-2 that deserve special attention, since compliance with their requirements is crucial for certification and release to the market of manufactured equipment. The use of a risk management matrix is proposed, which is used to provide quantitative indicators for each possible risk associated with a medical device in any mode of operation and possible malfunction.
Alguns gêneros e subgêneros de Laelapidae (Acari: Mesostigmata) associados com roedores e revalidados por meio de taxonomia numérica
Authors: Botelho José R. , Linardi Pedro M. , Maria Mário de
Published: March 2023

Samples of Laelapidae collected from wild and commensal rodents in Belo Horizonte, State of Minas Gerais, Brazil, and comprising nine operating taxonomic units were phenetically analyzed by using 44 characters of female mites. A phenogram indicated three clusters, with Androlaelaps rotundus (Fonseca, 1935) more closely related to Laelaps Koch, 1839 and Echinolaelaps Ewing, 1929 than to Androlaelaps foxi (Fonseca, 1957) and Androlaelaps fahrenholzi (Berlese, 1911). Systematic changes proposed as a result of this study include the revalidation of the genus Eubrachylaelaps Ewing, 1929 to include A. rotundus; the recognition of Echinolaelaps as a subgenus of Laelaps; at least, the division of the genus Androlaelaps Berlese, 1903 into two subgenera: Androlaelaps to include A. foxi and Haemolaelaps Berlese 1910 to include A. fahrenholzi.
Genetic differentiation and diversity of natural populations of Cryptocarya spp. (Lauraceae) from the Brazilian Atlantic rain forest
Authors: De Moraes Pedro L. R. , Monteiro Reinaldo , Vencovsky Roland
Published: March 2023

The genetic variability and structure of ten populations of Cryptocarya spp. (Lauraceae) were investigated by means of isozymes. Leaf samples of adult individuals of C. aschersoniana, C. moschata, and Cryptocarya sp., from two regions of São Paulo state, Brazil, were collected. Seeds from 35 families of C. moschata and juveniles of three populations from diaspores dispersed by “muriquis”, Brachyteles arachnoides (Primates - Cebidae), were also collected. From twenty loci analysed, the expected average heterozygosity of progenies, juveniles, and adults of C. moschata was respectively 0.313, 0.227, and 0.351, whereas it was 0.258 and 0.393 for C. aschersoniana and Cryptocarya sp., respectively. Results indicated that a greater variability occurred within populations for all categories analysed. For adult populations of C. moschata, the divergence obtained through GST estimates suggests the existence of significant genetic drift and/or natural selection effects between regions. The level of gene differentiation (GST = 0.107) was relatively high, and comparable to what would be expected for groups of plants having a half-sib family structure in a single generation. For juvenile populations, the genetic differentiation was also high (GST = 0.084). This could be explained by differential feeding behaviour of “muriquis” within their home range, allied to the distance among sites of seed dispersion. Nei’s average genetic distance (D) between pairs of C. moschata adult populations was 0.07, indicating again a pronounced genetic differentiation. Present values obtained from isozymes support morphological and wood anatomy evidences that C. moschata and C. aschersoniana are closely related species.

Published: March 2023

This work compares the nest distributions of the six most abundant species of stingless bees among three habitat types (structured, recovering and depleted forest) within a fragment of Atlantic Rain Forest: Tetragonisca angustula, Nannotrigona punctata, Partamona helleri, Scaptotrigona xanthotricha, Plebeia sp.n. and Scaptotrigona tubiba. The nests of these species represented, respectively, 31%, 12%, 9%, 7%, 6% and 5% of all stingless bees’ nests (n=137) found within an area of 11,3 ha. The frequency of nests found in each habitat and substratum type varied significantly among the six species. S. xanthotricha and S. tubiba were found to nest only in tree holes within structured forest, while T. angustula, P. helleri and Plebeia sp.n. were found in all three habitats. P. helleri was abundant in depleted forest, where it build partially exposed nests in manmade structures, frequently in association with termites. T. angustula and Plebeia sp. n. were the most abundant species in the recovering forest, nesting in tight association with the fast growing and dominant tree Tapirira guianensis. Simplification of forest structure in the recovering habitat clearly favors the population expansion of T. angustula. N. punctata occupies living trees in structured forest and artificial cavities in depleted habitat, where it is the most abundant nesting species. The unexpected absence of N. punctata in the recovering forest was partially attributed to exploitative competition with T. angustula.
Background matching and evolution of cryptic colours of selected passerines in deciduous woodlands
Authors: Bursell Jens , Dyck Jan
Published: March 2023

Most drab plumage colours are probably cryptic. Crypsis (camouflage) occurs when the colour of a significant part of the plumage is similar to the colour of a significant part of the background against which the prey bird may be detected by a potential predator. In this study we compare back colours of tits and associated species with colour backgrounds in their habitat during a four-month period in winter. We test the hypothesis that in some of the species back colour is similar to one of the background colours. In addition to colour backgrounds, microhabitats and tree species were also recorded. Great Tit Parus major, Nuthatch Sitta europea and Treecreeper Certhia familiaris showed distinct preferences for different colour backgrounds, reflecting their choice of microhabitats and tree species. The data suggest that in the Great Tit the olive-moss green back colour has evolved as crypsis for foraging close to the base of tree trunks, where most of the moss is found. The bluish-grey back colour of the Nuthatch is suggested to have evolved as crypsis against greyish beech trunks and branches. Similarly the brown back colour of the Treecreeper is suggested to have evolved as crypsis against pale brown- greyish brown bark surfaces. The possibility that the grey back colour of the Marsh Tit Parus palustris has evolved as crypsis against greyish branches is discussed. For the Blue Tit Parus caeruleus it is suggested that the green back colour has evolved as crypsis against leaves during summer; thus no background matching of the back occurs in winter. For the black back colour of the Longtailed Tit Aegithalos caudatos no background matching can be suggested. The study demonstrates that it is possible to quantify background colours for fouraging birds in the wild as seen by a human observer on the ground. It is proposed that these observations are also representative for a hunting Sparrowhawk Accipiter nisus, even though differences in observing height and possible differences in spectral visual range may present difficulties.

Predation on vertebrates by Neotropical passerine birds
Authors: Lopes Leonardo E. , Fernandes Alexandre M. , Marini Miguel Â.
Published: March 2023

We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs. Eighteen samples (0.3%) presented evidence of predation on vertebrates. Our bibliographic survey also provided records of 203 passerine species preying upon vertebrates, mainly frogs and lizards. Our data suggest that vertebrate predation by passerines is relatively uncommon in the Neotropics and not characteristic of any family. On the other hand, although rare, the ability to prey on vertebrates seems to be widely distributed among Neotropical passerines, which may respond opportunistically to the stimulus of a potential food item.

This study aims: (1) to determine the effect of crude extract of durian seeds on weed control in oil palm plantations, (2) to determine the effect of the herbicide oxyfluogen 240 g/L which is effective on weed control in oil palm plantations, (3) to determine the effect of interaction of crude extract of durian seeds and oxyfluogen herbicide on weeds in oil palm plantations. The method used in this study was a randomized block design with a factorial pattern. The first factor was durian seed extract (D) with a concentration consisting of 4 levels, namely: control (D0), 100 ml/L (D1), 200 ml/L (D2), 400 ml/L (D3). The second factor is the herbicide oxyfluogen (O) with a concentration consisting of 4 levels, namely: control (o0), 1 ml/L (O1), 2 ml/L (O2), 3 ml/L (O3). From these 2 factors, 16 treatments were obtained with 2 replications, and the number of samples was 32 sample plots, plot area 1 m2, distance between replicates 1 m from 2 factors. The results of data analysis showed that administration of durian seed extract and administration of oxyfluogen had a very significant effect on the percentage of weed mortality in oil palm plantations, but the interaction had no significant effect on the first week and second week after application. The best treatment was the application of a combination of 400 ml/L of durian seed extract with 3 ml/L of oxyfluogen which killed the highest weeds around 81% after two weeks of application. Durian seed extract has potential as a bioherbicide, which can be used as an alternative technique in weed control systems in oil palm plantations.

This study aimed to describe the development of types of fishing gear in the waters of the east coast of Sumatra from Belawan Waters to Serdang Bedagai Waters and to examine the perceptions of fishers based on the social characteristics of fishers towards environmentally friendly fishing gear based on the Code of Conduct for Responsible Fisheries (CCRF). The method used in this research is descriptive research using the survey method. The population in this study were fishers based in Belawan and Serdang Bedagai waters and using traps and gill nets, as many as 6943 people, with the simple sampling method or slovin method, the results of the sample count were 100 people from the population. Based on eight categories (CCRF) to understand fishers' perceptions of environmentally friendly fishing gear, including the level of selectivity, biodiversity, ecological diversity, not destroying habitat, the safety of fishers and consumers, based on social conditions, based on biodiversity, and based on fish quality, the level of very understanding is 13.2 %, understand 25.2%, neutral 26.7%, don't understand 23.3% and don't understand 11.4%. This study results indicate that the respondents, in general, have begun to realize environmentally friendly fishing gear based on the CCRF.

Electroencephalography (EEG) offers a wide range of uses in a variety of industries. Low SNR (signal to noise ratios), nevertheless, limit EEG applicability. EEG noise is caused by a variety of artifacts and numerous strategies have already been developed to identify and eliminate these inconsistencies. Various methods differ from merely identifying and discarding artifact ridden segments to isolating the EEG signal's noise content. With an emphasis on the previous half decade, we discuss a range of contemporary and traditional strategies for EEG data artifact recognition and removal. We assess the approaches' merits and drawbacks before proposing potential prospects for the area.

Authors: Singh Chhina Gurpreet , Gupta Namit , Naina Naina , Batra Pranjali
Published: March 2023

AIM : The study aimed to nd the link between the fat deposition in pancreas and liver and metabolic syndrome. METHODOLOGY : It was a
cross sectional study . 50 patients with ultrasonographic evidence of fatty pancreas were included and were evaluated for the presence of fatty liver
on ultrasonography and were assessed for the presence of metabolic syndrome. RESULTS: Metabolic syndrome was detected in 62% of patients
of Non alcoholic fatty pancreas disease (NAFPD). The overall prevalence of fatty liver was 72% in patients with NAFPD. The presence of fatty
liver in the studied patients increased the number of parameters of metabolic syndrome. It was statistically signicant (p=0.043). CONCLUSION:
NAFPD is closely related to metabolic syndrome and fatty liver
OSSEODENSIFICATION CONCEPT IN IMPLANT DENTISTRY

Published: March 2023

Implant success is evaluated on the basis of the stability gained at the junction of the bone to the implant. The stability needed for the successful
future outcomes are of two types, i.e., primary stability which is acquired while placing the implant and secondary stability acquired by
osseointegration. At present a new idea of Osseodensication has been established for the preparing the osteotomy site for the insertion of the
implant. It is a bone non-extraction technique for osteotomy site preparation. There is a low plastic deformation of bone caused by rolling plus
sliding contact with osteotomes or densifying burs which have utes to densify bone as it drills into it and expand osteotomy site. This technique
permits bone preservation along with its condensation by compaction autografting of bone through osteotomy site preparation resulting in
enhanced peri-implant bone density, healing and mechanical stability as well as minimised micromotion of the implant. This clinical approach is
valuable at the sites where there is anatomic paucity of the bone
TRU-CUT ISOLATED PAROTID METASTASIS FROM RENAL CELL CARCINOMA: AN UNUSUAL PRESENTATION AND REVIEW OF LITERATURE
Authors: Irshad Bhat Fibah , Faisal Masood Pirzada , Mushtaq Humaira
Published: March 2023

Background: Renal cell carcinoma with isolated metastasis to the parotid gland is extremely rare. Slow growth, low level of suspicion and
negative Fine needle aspiration cytology (FNAC) often delay the diagnosis. A high level of suspicion of metastatic disease from a specic site is
important, otherwise can be missed for a benign swelling leading to delayed treatment and poorer prognosis. A 59-year-old Case presentation:
male presented with a swelling in the right preauricular area 5 years post right radical nephrectomy for right renal cell carcinoma (RCC). The
examination was suggestive of a benign swelling. FNAC was done twice, which was inconclusive. A Tru-cut biopsy of the lesion revealed
metastatic RCC. MRI revealed a dumbbell type of tumor extending deep into the gland and encasing vessels. PET-CT was negative for metastasis
to the rest of the body. The patient received targeted therapy followed by radiation therapy with imaging showing non-progression of the disease.
Conclusion: Metastatic disease should be considered whenever a parotid mass is detected in patients with an RCC history. Examination ndings
can be misleading; hence dedicated imaging is critical. Small parotid metastasis can be cured with surgery. A combination of chemotherapy and
radiation therapy can palliate the unresectable disease.

Published: March 2023

 The proposed EMG data acquisition band, which utilizes seven electrodes, has the potential to revolutionize gesture recognition. Unlike conventional EMG data acquisition methods that necessitate skin preparation and can cause skin irritation or adverse reactions, this band is inexpensive, user-friendly, and capable of capturing high-quality EMG signals. Our study evaluated the performance of the proposed EMG band by comparing it with established techniques on eight healthy subjects, and the results revealed that it achieved comparable or significantly better performance in terms of classification accuracy. This suggests that our EMG data acquisition band has significant practical applications, particularly in prosthetic hand control, where real-time processing is critical. Moreover, The proposed feature extraction method based on spectral moments also exhibited significant improvements in terms of classification accuracy, class separability, and processing time, making it a promising alternative for gesture recognition applications. Additionally, the proposed feature set was computationally efficient, with a maximum computation time of 250.209 milliseconds, making it suitable for real-time prosthetic hand control. 
Deterministic Decoupling of Global Features for Data Analysis
Authors: Martínez-Enríquez Eduardo , González Maria del Mar , Portilla Javier
Published: March 2023

 We introduce a method for deterministic decoupling of global features with application to data analysis. We propose a new formalism that is based on defining transformations on submanifolds, by following trajectories along the features’ gradients. Through these transformations, we define a type of normalization that, we demonstrate, allows for decoupling differentiable features. We apply this to sampling moments, obtaining a quasi-analytic solution for the orthokurtosis, a normalized version of the kurtosis that is not just decoupled from mean and variance, but also from skewness. We also apply the proposed method, up to sixth-order moments, in the original data domain and at the output of a filter bank, to regression and texture classification problems, consistently obtaining strong improvements in performance as compared to using classical (non-decoupled) features
