A color-digit Stroop task shows numerical influence on numerosity processing
Authors: Hershman Ronen , Beckmann‏ Lisa , Keha Eldad , Wagner Michael , Kaufmann Liane , Henik Avishai
Published: September 2024

The numerical Stroop task involves presenting participants with two digits that differ in physical size and numerical value and asking them to report which digit had the larger size or value while ignoring the other dimension. Previous studies show that participants have difficulty ignoring the irrelevant dimension and thus have implications on the automaticity of numerical processing. The present study investigates the automatic influence of numerical value on numerosity processing in a novel Stroop-like task. In two experiments, participants were presented with digits made of colored stripes and asked to identify the number of different colors. In both experiments, interference and facilitation effects were found, supporting the automaticity of symbolic number processing and its influence on numerosity processing. These findings expand upon previous research on numerical as well as counting Stroop tasks, and have potential implications for studying interference and basic numerical processing in children and clinical populations.

FACTORS CONTRIBUTING TO EMPLOYEES’ COMMITMENT AND ITS IMPLICATION ON ORGANIZATIONAL OWNERSHIP BEHAVIOUR: EVIDENCE FROM 5 SELECTED PRIVATE HIGHER LEARNING INSTITUTIONS IN RWANDA
Authors: UMUMARARUNGU CHRISTINE KAPITA , BAZUBAGIRA APPOLINE KABERA
Published: September 2024

The study assessed factors contributing to employees’ commitment and its implication on Organizational Ownership Behaviour in Rwanda considering Private Higher Learning Institutions (HLIs) as case study. The aim of the research was to examine factors contributing to employees’ commitment as well as the dimensions of employees’ commitment and Organization Ownership Behaviour. Data was collected from 5 Private HLIs with a sample of 24 employees in each which makes a total number of 120 respondents. The findings revealed that employees’ commitment is grounded on a combination of different factors namely employees’ involvement in decision making, open communication, organizational culture, work environment and career growth opportunities. The results highlighted that HLIs do not put more emphasis on enhancing various dimensions of employees’ commitment. It was also revealed that 47.6% of respondents are not proud of their work place, 44.5% work due to lack of alternative employment opportunities which affect their level of performance. From selected HLIs, 36.1% avowed that they do not feel concerned with problems of employing organizations. The study concluded that HLIs lack proper management of employees as key players of academic excellence. It was found out that there is lack of emphasis on employees’ commitment factors which in turn lead to Organization Ownership Behaviour. It has been proved that if employers take care of their employees, they will in turn satisfy the organization customers’ needs. The study recommends Private HLIs effectively manage employees so that they may successfully accomplish their duties and responsibilities. This would lead towards better employees’ performance and good quality of education.

Enhancing Breast Cancer Diagnosis Through Clustering: A Study of KMeans, Agglomerative, and Gaussian Mixture Models
Authors: Suryawanshi Nikhil Sanjay
Published: September 2024

In the evolving landscape of medical data analysis, clustering techniques play a pivotal role, particularly in deciphering intricate patterns within datasets, such as those linked to cancer diagnostics. With the continuous expansion and increasing complexity of healthcare data, there is a growing demand for effective clustering algorithms capable of extracting significant insights. Current trends underscore the necessity of carefully selecting the most appropriate clustering method to improve both the accuracy and interpretability of analytical results. In this paper, we conduct a comprehensive comparison of three prominent clustering algorithms - KMeans, Agglomerative Clustering, and Gaussian Mixture Model (GMM) - applied to a breast cancer dataset comprising features from Fine Needle Aspirates (FNA) of breast masses. Following a thorough preprocessing and scaling of the features, we assess the performance of these clustering techniques using the Silhouette Score, Calinski-Harabasz Score, and Davies- Bouldin Score. The findings reveal that KMeans provides superior cluster separation and clarity relative to the other algorithms. This research emphasizes the critical role of algorithm selection based on specific dataset attributes and evaluation metrics, aiming to enhance the accuracy of clustering outcomes in breast cancer classification.

In today's landscape, safeguarding sensitive data is crucial for Organizations, but navigating data protection regulations and ensuring compliance is increasingly challenging. This research project explores Organizations' hurdles in achieving data protection compliance, offering insights to develop more effective strategies. A survey via Google Forms gathered insights from data protection experts and professionals, revealing key challenges such as difficulty understanding complex regulations, limited resources, and obstacles in implementing compliance measures. The study also reviewed the existing data protection regulatory framework and relevant literature, uncovering a common theme of confusion and a gap between regulatory requirements and practical application across Organizations. The research recognises that data protection extends beyond regulatory compliance, reflecting the evolving expectations of individuals and customers regarding the ethical handling of their data. This underscores the importance of data protection as both a legal and ethical responsibility closely tied to organisational reputation and public trust. The findings highlight the need for more precise, accessible guidelines and support mechanisms to bridge the gap between regulatory demands and organisational implementation. By addressing these challenges, Organizations can strengthen their data protection measures, foster trust, and ensure the security of sensitive information.

Studying Binary Formation under Dynamical Friction Using Hill’s Problem
Authors: Dodici Mark , Tremaine Scott
Published: September 2024

Using the equations of motion from Hill’s problem, with added accelerations for different forms of dynamical friction, we provide the (to-date) broadest scale-free study of friction-driven binary formation in gaseous disks and stellar clusters. We focus mainly on binary formation between stellar-mass black holes in active galactic nuclei (AGNs), considering both gas dynamical friction (GDF) from AGN disks and stellar dynamical friction (SDF) from the nuclear star cluster. We first find simple, dimensionless friction coefficients that approximate the effects of standard models for GDF and SDF. We perform extensive simulations of Hill’s problem under such friction, and we present a picture of binary formation through encounters between single stars on nearby orbits, as a function of friction parameter, eccentricity, and inclination. Notably, we find that the local binary formation rate is a linear function of the friction coefficient so long as the friction is weak. Due to the dimensionless nature of our model problem, our findings are generalizable to binary formation at all scales (e.g., intermediate-mass black holes in a star cluster, planetesimals in a gaseous disk).

Published: September 2024

We present the observational evidence of the existence of a double-decker filament channel (FC) by using observations in extreme ultraviolet and Hα wavelengths. For both FCs, the east foot-point roots in the active region (AR), while the west one roots in the remote quiet region. The bottom FC (FC1) appears as intermittent filaments. Within the AR, the FC1 appears as an S-shaped filament (F1), which consisted of two J-shaped filaments (F1S/F1N for the south/north one). For the upper one (FC2), only the east part is filled with dark plasma and visible as a small filament (F2). Its east foot-point roots around the junction of F1S and F1N. Initially, due to the recurrent reconnections, F1N and F1S link to each other and form a new filament (F3) thread by thread. Meanwhile, the heated plasma, which appears as brightening features, flows from the east foot-point of F2 to the west, and becomes invisible about 1.1 × 105 km away. The failed eruption of F1S is triggered by the reconnection, which appears as the brightening threads changing their configuration from crossed to quasiparallel in between the F1S and F3, and is confined by the upper magnetic field. Associated with the eruption, the distant invisible plasma becomes visible as a brightening feature. It continuously flows to the remote foot-point, and becomes invisible before reaching it. The brightening plasma flow outlines the skeleton of FC2 gradually. The observations show the existence of a double-decker FC, as a magnetic structure, before they appear as a brightening/dark feature when fully filled with hot/cool plasma.

Published: September 2024

The LHS 6343 system consists of a resolved M-dwarf binary with an evolved, negligibly irradiated brown dwarf (BD), LHS 6343 C, orbiting the primary star. Such BD eclipsing binaries present rare and unique opportunities to calibrate substellar evolutionary and atmosphere models since mass, radius, temperature, and luminosity can be directly measured. We update this BD’s mass (62.6 ± 2.2 M
Jup) and radius (0.788 ± 0.043 R
Jup) using empirical stellar relations and a Gaia Data Release 3 distance. We use Hubble Space Telescope/Wide Field Camera 3 (WFC3) observations of an LHS 6343 C secondary eclipse to obtain a near-IR emission spectrum, which matches to a spectral type of T1.5 ± 1. We combine this spectrum with existing Kepler and Spitzer/IRAC secondary-eclipse photometry to perform atmospheric characterization using the ATMO-2020, Sonora-Bobcat, and BT-Settl model grids. ATMO-2020 models with strong nonequilibrium chemistry yield the best fit to observations across all modeled bandpasses while predicting physical parameters consistent with Gaia-dependent analogs. BT-Settl predicts values slightly more consistent with such analogs but offers a significantly poorer fit to the WFC3 spectrum. Finally, we obtain a semi-empirical measurement of LHS 6343 C’s apparent luminosity by integrating its observed and modeled spectral energy distribution. Applying knowledge of the system’s distance yields a bolometric luminosity of log(L
bol/L
☉) = −4.77 ± 0.03 and, applying the Stefan–Boltzmann law for the known radius, an effective temperature of 1303 ± 29 K. We also use the ATMO-2020 and Sonora-Bobcat evolutionary model grids to infer an age for LHS 6343 C of

UVIT Survey of the Host Galaxies of Active Galactic Nuclei. I. Star Formation Scenarios
Authors: Nandi Payel , Stalin C. S. , Dam Poulomi , Saikia D. J.
Published: September 2024

Circumnuclear star formation (SF) is generally seen in galaxies hosting active galactic nuclei (AGN); however, the connection between the AGN activity and SF in them is less well understood. To explore this connection on scales of a few tens of parsecs to a few tens of kiloparsecs and larger, we carried out an investigation of SF in seven Seyfert-type AGN and one low-ionization nuclear emission-line region galaxy, using observations with the Ultraviolet Imaging Telescope on board AstroSat in the near-ultraviolet (2000–3000 Å) and far-ultraviolet (1300−1800 Å) bands. A total of 1742 star-forming regions were identified, having size scales of 0.010–63.642 kpc2. Considering all the galaxies, we found a positive correlation between their total surface density of SF (ΣSFR) and extinction. For five galaxies, namely NGC 1365, NGC 4051, NGC 4321, NGC 5033, and NGC 6814, we found a gradual decrease of both extinction and ΣSFR from the centre to the outer regions. Four sources are found to lie in the main sequence of star-forming galaxies, and the other four lie away from it. We found the ratio of the star formation rate (SFR) in the nuclear region to the total SFR to be positively correlated with the Eddington ratio. This points to the influence of AGN in enhancing the SF characteristics of the hosts. However, the impact is dominant only in the central nuclear region and has no significant effect on the larger scales probed in this work.
A Spatial Uniformity Check of Gaia DR3 Photometry and BP/RP Spectra
Authors: Huang 黄 Bowen 博闻 , Yuan 苑 Haibo 海波 , Xiao 肖 Kai 凯
Published: September 2024

Gaia DR3 photometry and Blue Photometer (BP) and Red Photometer (RP) spectra have been widely used as reference in photometric calibrations. In this work, we check the spatial uniformity of Gaia DR3 photometry and BP/RP spectra by comparing the BP, RP, and G-band photometry with the synthetic ones from the BP/RP spectra. The discrepancies have a small dispersion of 1.07, 0.55, and 1.02 mmag for the BP, RP, and G bands, respectively. However, the discrepancies exhibit obvious spatial patterns, which are clearly associated with Gaia’s scanning law. The patterns observed in the BP and G bands are similar, with discrepancies between photometry and spectra being more pronounced in these bands compared to the RP band. A further independent test with the Dark Energy Survey DR2 photometry reveals that the spatial patterns are more likely attributed to the Gaia DR3 BP/RP spectra, particularly in the BP band. On one hand, our results confirm the high spatial uniformity of Gaia data at the mmag level. On the other hand, our results suggest that the spatial uniformity of Gaia DR3 BP/RP spectra is not as good as that of Gaia DR3 photometry, and could be further improved in the future.
Critical aortic stenosis presenting as recurrent bleeding per rectum, a case report and review of literature
Authors: Venkatesh A. , Raghuram A.R. , Kumar A.M.
Published: September 2024

Introduction: Heyde syndrome is a multisystem disorder characterized by the triad of aortic stenosis, acquired coagulopathy (von Willebrand syndrome type 2A) and gastrointestinal angiodysplasia. The diagnosis of Heyde syndrome in adults is challenging because of high frequency of aortic stenosis and gastrointestinal angiodysplasia. Clinical suspicion is therefore essential for diagnosis. Case Presentation: We present the case of a male with recurrent hospital admissions and transfusions for anemia post bleeding per rectum who was diagnosed to have Heyde’s syndrome. The patient was managed with aortic valve replacement and coronary artery bypass surgery involving left anterior descending artery. He remained symptom free 1 year after appropriate therapy. Conclusions: The management of aortic stenosis in patients with Heyde syndrome results in resolution of anemia. Hence, treatment decisions are based on correct identification.
A single centre retrospective study on balloon assisted technique in transcatheter closure of large atrial septal defects
Authors: Logesh M.R. , Speedie A. , George O.K. , Alex A.G. , Karuppusamy R.
Published: September 2024

Background: Data on balloon-assisted techniques (BAT) for transcatheter closure (TCC) of ostium secundum atrial septal defect (ASD-II) is scarce. The objective was to study the outcomes of the balloon-assisted technique (BAT) for transcatheter closure (TCC) of ostium secundum atrial septal defect. A single-centre retrospective study of patients with ostium secundum ASD who underwent balloon-assisted TCC. Results: This study included 36 patients. Thirty-three out of 36 patients with ASD-II and complex morphological features underwent successful BAT TCC. Our cohort of patients had a high prevalence of inadequate/floppy Aortic (90%), Posterior (40%) and Superior/Right upper pulmonary vein (25%) rims. Procedural success was defined as stable device position on post-procedure echocardiogram at 24-48 hours with no residual shunt. BAT was successful in 33 out of 36 patients (91.6%). The mean ASD size with BAT success was 27 mm. BAT was unsuccessful in 3 out of 36 patients. The combined deficiency and floppy nature of the Aortic, Superior, and Posterior rims was the reason for the failure of the Balloon-assisted technique along with the large size of ASD-II. BAT-failed patients were referred for emergent surgical device retrieval and closure of the atrial septal defect. No procedure-related mortality was encountered. Conclusions: Balloon-assisted device closure of ASD had a 90% success rate. BAT is a safe and effective technique in patients with large ASD-II. This technique enables controlled device delivery and alignment when conventional techniques fail.
Bifurcation and optimal harvesting analysis of a discrete-time predator–prey model with fear and prey refuge effects
Authors: Liu Jie , Wang Qinglong , Cao Xuyang , Yu Ting
Published: September 2024

In this contribution, the complicated dynamical behaviors and optimal harvesting policy of a discrete-time predator–prey model with fear and refuge effects are formulated. Both the fear and prey refuge effects refer to an interaction between predator and prey. In the first place, the existence and local stability of three fixed points of proposed model are investigated by virtue of our methodology, that is, the eigenvalues of the Jacobian matrix. One step further, it is worth mentioning that the model undergoes flip bifurcation (i.e., period–doubling bifurcation) and Neimark–Sacker bifurcation at the interior fixed point by the utilization of bifurcation theory and center manifold theory. Also, optimal harvesting strategy is investigated, and the expressions of optimal harvesting efforts are determined. Two examples, in the end, are put forward to prove that they are consistent with the previous theoretical results.

Published: September 2024

In applied and computational mathematics, quaternions are fundamental in representing three-dimensional rotations. However, specific types of quaternionic linear matrix equations remain few explored. This study introduces new quaternionic linear matrix equations and their necessary and sufficient conditions for solvability. We employ a methodology involving lemmas and ranks of coefficient matrices to develop a novel algorithm. This algorithm is validated through numerical examples, showing its applications in advanced fields. In control theory, these equations are used for analyzing control systems, particularly for spacecraft attitude control in aerospace engineering and for control of arms in robotics. In quantum computing, quaternionic equations model quantum gates and transformations, which are important for algorithms and error correction, contributing to the development of fault-tolerant quantum computers. In signal processing, these equations enhance multidimensional signal filtering and noise reduction, with applications in color image processing and radar signal analysis. We extend our study to include cases of $ \eta $-Hermitian and i-Hermitian solutions. Our work represents an advancement in applied mathematics, providing computational methods for solving quaternionic matrix equations and expanding their practical applications.

To improve the quality of photovoltaic (PV) data and power prediction accuracy, a PV power prediction method based on neighborhood rough set and Pearson correlation coefficient (NRS-PCC) feature selection and multi-scale convolutional neural networks and long short-term memory (CNN-LSTM) network is proposed. We first calculate the correlation between different PV features based on PCC and select strongly correlated features to cross-multiply to get the fusion features to enrich the data source. Then, dimensionality reduction of the fusion features by NRS. Finally, correlation analysis based on PCC on the dimensionality reduction of the fusion features to screen out the effective features. Furthermore, a multi-scale CNN-LSTM is designed to predict PV power. The output vectors of different convolutional layers are first fused to extract multi-scale features, then the features of different scales are spliced as the input of the LSTM network, and finally, the LSTM network performs regression prediction. The effectiveness of the proposed method is verified on a real PV power dataset.
A INDÚSTRIA DE JOGOS ELETRÔNICOS NO BRASIL: UMA BREVE HISTÓRIA E SUAS IMPLICAÇÕES NA ATUALIDADE

Published: September 2024

A indústria de jogos eletrônicos é uma das que mais se destaca em âmbito global, devido ao seu potencial de arrecadação e ao mercado consumidor, que no ano de 2023 alcançou 3,3 bilhões de pessoas. Mas, esse ramo produtivo não foi difundido de maneira homogênea, com uma grande diferença entre os países capitalistas centrais e os países periféricos. Isto posto, o objetivo precípuo da pesquisa é analisar como foi o processo de consolidação da indústria de jogos eletrônicos no Brasil e os seus desdobramentos, sobretudo na atualidade. A metodologia da pesquisa é quali-quantitativa e consiste na revisão bibliográfica dos processos centrais, com destaque para a história dos games, e também na coleta e posterior sistematização de dados e indicadores referentes a algumas variáveis dessa indústria. Os resultados mostram que apesar do expressivo consumo de jogos eletrônicos, as desenvolvedoras brasileiras enfrentam adversidades na produção, a exemplo da elevada tributação e as ausências de políticas governamentais de incentivo e de cursos de capacitação. Esses problemas existiam no final do século XX e permanecem nos dias de hoje. Contudo, em abril de 2024, foi votado e aprovado na Câmara dos Deputados, o Projeto de Lei (PL) 2.796/2021, que tenciona reverter esse cenário.
HDAC6 Deletion Decreases Pristane-induced Inflammation

Systemic lupus erythematosus is an autoimmune disease characterized by excessive inflammation and production of pathogenic Abs. Histone deacetylase 6 (HDAC6) is a class IIb histone deacetylase. It has been reported that selective HDAC6 inhibition decreases inflammation in lupus mouse models. In this study, sex- and age-matched wild-type (WT) and HDAC6−/− mice on the C57BL/6 background were administered 0.5 ml of pristane or PBS i.p. at 8–12 wk of age and were euthanized 10 d later. At sacrifice, body weight and spleen weight were measured, sera were collected, and splenocytes and peritoneal cells were harvested for flow cytometry. We found pristane administration increased the spleen weight with no difference between WT and HDAC6−/− mice. Pristane administration promoted the population of CD11b+Ly6C++ inflammatory monocytes and CD11b+Ly6G+ neutrophils. Peritoneal recruitment of these inflammatory monocytes and neutrophils was significantly decreased in HDAC6−/− mice compared with the WT mice. Flow cytometry results showed that the number of CD69+ T and B cells was increased in HDAC6−/− mice. Pristane administration also induced the IFN signature genes as determined by RT-qPCR. Furthermore, IFN signature genes were not affected in HDAC6−/− mice compared with the WT mice. In vitro studies in J774A.1 cells revealed that the selective HDAC6 inhibitor (ACY-738) increased acetylation of NF-κB while increasing Stat1 phosphorylation, which resulted in inducible NO synthase production in LPS/IFN-γ–stimulated cells. Taken together, these results demonstrate that although HDAC6 inhibition may inhibit some inflammatory pathways, others remain unaffected.

Bruton tyrosine kinase (BTK) is a kinase expressed by various immune cells and is often activated under proinflammatory states. Although the majority of BTK-related research has historically focused on B cells, understanding the role of BTK in non-B cell populations is critical given myeloid cells also express BTK at comparable levels. In this study, we investigated and compared how BTK inhibition in human and murine myeloid cells alters cell phenotype and function. All experiments were performed using two BTK inhibitors (evobrutinib and tolebrutinib) that are currently in late-stage clinical trials for the treatment of multiple sclerosis. Assays were performed to assess the impact of BTK inhibition on cytokine and microRNA expression, phagocytic capacity, and cellular metabolism. In all cells, both evobrutinib and tolebrutinib significantly decreased phosphorylated BTK and LPS-induced cytokine release. BTK inhibition also significantly decreased the oxygen consumption rate and extracellular acidification rate in myeloid cells, and significantly decreased phagocytosis in murine-derived cells, but not human macrophages. To further elucidate the mechanism, we also investigated the expression of microRNAs known to impact the function of myeloid cells. BTK inhibition resulted in an altered microRNA expression profile (i.e., decreased miR-155-5p and increased miR-223-3p), which is consistent with a decreased proinflammatory myeloid cell phenotype. In summary, these results provide further insights into the mechanism of action of BTK inhibitors in the context of immune-related diseases, while also highlighting important species-specific and cell-specific differences that should be considered when interpreting and comparing results between preclinical and human studies.
