Published: September 2024

Esta investigación tiene como objetivo analizar la interrelación entre el espacio urbano y la vulnerabilidad socioambiental del sector “El Negrital”, Portoviejo, Manabí, Ecuador. A través de un enfoque metodológico mixto, que incorporó tanto la investigación bibliográfica como la investigación de campo, se reveló una estrecha conexión entre la calidad de vida de los residentes y las deficiencias en la provisión de servicios básicos, la infraestructura vial y la escasez de espacios verdes. Estas carencias han generado un entorno urbano vulnerable, exponiendo a la comunidad a riesgos y limitando sus oportunidades. Los resultados obtenidos evidencian la urgencia de una intervención integral que busque reducir las desigualdades socioespaciales y fortalecer la resiliencia del sector. Se propone un plan de acción que promueve la creación de un entorno urbano más sostenible y equitativo, mediante la mejora de la infraestructura, la diversificación de los usos del suelo y la generación de espacios verdes, con la finalidad de garantizar una mejor calidad de vida para los habitantes de "El Negrital" y contribuir a un desarrollo urbano más justo y equilibrado.

Los resultados destacan claramente la existencia de vulnerabilidades socioambientales relacionadas con el estado deficiente del espacio urbano. Estas deficiencias se reflejan en la percepción de los residentes y se asocian con la falta de servicios básicos, equipamientos inadecuados, falta de mantenimiento del espacio público, ausencia de mobiliario urbano y áreas de esparcimiento insuficientes.

Published: September 2024

предложен улучшенный способ шумоподавления двумерного изображения, основанный на вейвлет-преобразовании и сверточной нейронной сети, позволяющий подавить данные случайного шума, создаваемого внешними или внутренними факторами, снижая резкость изображений с беспилотных летательных аппаратов (БПЛА). Действительный сигнал отличается от шума после вейвлет-преобразования, и преобразованный сигнал служит входными данными нейронной сети. Глубокая нейронная сеть используется для непосредственного изучения характеристик шума на изображении, связанных с вейвлет-областью, что позволяет точно и адаптивно оценивать уровень и распределение шума. Сверточная нейронная сеть удаляет шум из сигнала с помощью чистого сигнала, который использует как эталонный в качестве отмеченных данных. Полученные изображения, несущие шум, разложены с использованием 2D-вейвлетов, ранжируя разложенные высокочастотные и низкочастотные коэффициенты, чтобы сформировать набор данных. Результаты моделирования показывают, что предложенный метод обеспечивает более высокую производительность шумоподавления с точки зрения пикового отношения сигнал/шум и среднеквадратической ошибки по сравнению с методами, использующими только нейронные сети. Представлен анализ влияния количества слоев сверточной нейронной сети на эффективность удаления шума нейронной сетью на основе вейвлет-преобразования
this article proposes an improved method for noise reduction of a two-dimensional image based on wavelet transform and a convolutional neural network,which allows suppressing random noise data generated by external or internal factors, reducingthe sharpness of images from unmanned aerial vehicles (UAVs). The actual signal differs from the noise after the wavelet transform and the transformed signal serves as input datato the neural network. A deep neural network is used to directly study the noise characteristicsin an image associated with the wavelet domain, which allows accurate and adaptive assessment of the noise level and distribution.A convolutional neural network removes noise froma signal using a pure signal, which it uses as a reference as marked data. The resulting noise-carrying imagesare decomposed using 2D wavelets, ranking the decomposedhigh-frequency and low-frequency coefficients to forma dataset. The simulation results show thatthe proposed method provides higher noise reduction performance in terms of peak signal-to-noise ratio and RMS error compared with methods using only neural networks. The analysis of the influence of the number of layersof a convolutional neural network on the efficiency of noise removalby a neural network basedon a wavelet transform is presented

Abstract
We present Crab X-ray polarization measurements using Imaging X-Ray Polarimetry Explorer (IXPE) data with a total exposure of 300 ks, three times more than the initial 2022 discovery paper. Polarization is detected in three times more pulsar phase bins, revealing an S-shaped +40° polarization angle sweep in the main pulse and >1σ departures from the OPTIMA optical polarization in both pulses, suggesting different radiation mechanisms or sites for the polarized emission at the two wavebands. Our polarization map of the inner nebula reveals a toroidal magnetic field, as seen in prior IXPE analyses. Along the southern jet, the magnetic field orientation relative to the jet axis changes from perpendicular to parallel and the polarization degree decreases by ∼6%. These observations may be explained by kink instabilities along the jet or a collision with a dense, jet-deflecting medium at the tip. Using spectropolarimetric analysis, we find asymmetric polarization in the four quadrants of the inner nebula, as expected for a toroidal field geometry, and a spatial correlation between polarization degree and photon index.
On the Cosmic Variance of the Merger Rate Density of Binary Neutron Stars
Authors: Chen Zhiwei , Lu Youjun , Wang Jie , Jiang Zhen , Chu Qingbo , Ma Xianghao 
Published: September 2024

Abstract
The cosmic variance on the star formation history may lead to bias in the merger rate density estimation of binary neutron star (BNS) mergers by compact binary population synthesis. In this paper, we take advantage of the large box size of the Millennium Simulation combined with the semianalytic galaxy formation model GABE and the parameterized population binary star evolution model to examine how much effect the cosmic variance will introduce on the estimation of the merger rate density of BNS mergers. We find that for subbox sizes of 100 and 200 Mpc, the variance of merger rate density σ

R
/R at different redshifts is about 23%–35% and 13%–20%, respectively. On the one hand, as for the variance of the detection rate on BNS mergers with the current LIGO–Virgo–KAGRA (LVK) detector network, this value is very small at ≲10%, which indicates ignoring the cosmic variance is reasonable for estimating the merger rate density from current LVK observations. On the other hand, with next-generation gravitational wave detectors, it is possible to localize BNS mergers within subboxes possessing a length of 40 Mpc for a source redshift z

s
< 0.2. In such a small box, the cosmic variance of the merger rate density is significant, i.e., the value of σ

R
/R is about ∼55%. This hints that estimating the merger rate density of BNS in different sky areas may provide useful information on the cosmic variance.
Caught in the Act: Observations of the Double-mode RR Lyrae V338 Boo during the Disappearance of a Pulsation Mode

Abstract
New results on the behavior of the double-mode RR Lyrae V338 Boo are presented. The Transiting Exoplanet Survey Satellite (TESS) observed this star again in 2022, and an observing campaign of the American Association of Variable Star Observers (AAVSO) was completed after the TESS observations as a follow-up. We find that the first overtone pulsation mode in this star completely disappears during the TESS observing window. This mode reappears at the end of the TESS observations, and the AAVSO observing campaign shows that in the months that followed, the first overtone mode was not only present but was the dominant mode of pulsation. This star, and potentially others like it, could hold the key to finally solving the mystery of the Blazhko effect in RR Lyrae.

Published: September 2024

Purpose
In dementia family caregiving, caregiver psychopathology has been frequently identified as a possible risk factor for the use of physically abusive, psychologically abusive, and neglectful behaviors toward care recipients. Yet, the mechanistic role of psychopathology in the use of these behaviors is not understood. The purpose of the current study is to determine the role of caregiver mental health in their daily risk of engaging in physically and psychologically aggressive and neglectful behaviors toward their care recipient with dementia.

Method

We used an intensive longitudinal design to survey family caregivers daily over 21 days. Using generalized linear mixed models, we evaluated the differential impact of caregivers' (
N
= 453) experience of major depression and generalized anxiety disorders measured at baseline versus 9,513 daily ratings of depressive and anxiety symptom severity, and interactions across levels, on the daily odds of engaging in physically abusive, psychologically abusive, and neglectful behaviors.

Results
Caregivers with clinically significant depression or anxiety at baseline had higher daily odds of engaging in each type of abusive and neglectful behavior. Worsened depressive symptoms (compared to individuals' average across all days) on a given day were associated with increased odds of engaging in psychologically and physically aggressive behaviors on the same day. Worsened anxiety symptoms on a given day were associated with increased odds of psychologically aggressive and neglectful behaviors.

Conclusion

A key finding was lack of a significant interaction effect between depression and anxiety disorders and mental health symptomology on the daily odds of engaging in abusive and neglectful behaviors. This finding indicates that daily depressive and anxiety symptoms are generalizable intervention targets across the family caregiver population and do not only increase risk among family caregivers with depressive and anxiety disorders.

Feasibility of a Culture-Based Multicomponent Cognitive Training Program for Older Adults With Dementia
Authors: Chen Ming-Hsin , Yu Ching-Len , Chang Su-Hsien 
Published: September 2024

Purpose
To understand whether a culture-based multicomponent cognitive training program is feasible and tolerable for persons with dementia (PWD) in day care centers in Taiwan, and to examine the effectiveness of a 16-week program in preventing declines in cognitive function and self-care, as well as the development of depressed mood and behavioral problems.

Method

This study was a 4-month cluster randomized controlled trial. PWD (
N
= 56) who met sample selection criteria were recruited from five day care centers and assigned to the experimental or comparison group. Participants in the experimental group received a series of culture-based multicomponent cognitive training activities via research assistants and day care center caregivers for 16 weeks. Participants in the comparison group received usual daily activities. Time attending activities and degree of participation were used as criteria for determining feasibility and tolerability of the program.

Results
Results confirmed the feasibility of culture-based multicomponent cognitive training activities if the activities were guided by caregivers. Results also showed participants in the experimental group had statistically significant improvements in cognitive function. Activities of daily living performance, depressed mood, and behavioral problems showed non-significant improvements.

Conclusion

The current study suggests that this program can assist PWD in preventing declines in self-care and the development of behavioral and psychological problems, and improve their cognitive function. Further research with a larger sample size and staff training should be considered to test the effectiveness of this program. [

Authors: Nsele Nhlanhla W. , Mathobela Kegomoditswe P. , Radebe Siyabonga P. , Thembane Nokukhanya 
Published: September 2024

Background: Antibiotic resistance is a significant public health challenge, exacerbated by resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA).Aim: This study investigates the synergistic antibacterial effects of Psidium guajava aqueous extract combined with procaine penicillin against MRSA, methicillin-sensitive S. aureus (MSSA) and Enterococcus faecalis.Setting: In-vitro study conducted under controlled laboratory settings at the Mangosuthu University of Technology, Department of Biomedical Sciences, Kwa-Zulu Natal, South Africa.Methods: Psidium guajava leaves were collected and prepared according to the German Homeopathic Pharmacopoeia, while procaine penicillin was diluted for testing. The combination treatment was evaluated using the Kirby–Bauer Antimicrobial Sensitivity Test and Minimum Inhibitory Concentration (MIC) assays.Results: Results showed that the combination of P. guajava extract and procaine penicillin significantly enhanced the antibacterial activity against MRSA, as evidenced by larger zones of inhibition and lower MIC values compared to P. guajava extract and procaine penicillin on their own. However, no significant difference was observed against MSSA and E. faecalis.Conclusion: The findings suggest that P. guajava extract could potentiate the efficacy of procaine penicillin against MRSA, providing a potential alternative strategy to combat antibiotic-resistant bacteria.Contribution: The study revealed that P. guajava aqueous extract enhances the antibacterial efficacy of procaine penicillin specifically against MRSA, suggesting a potential alternative treatment strategy for antibiotic-resistant infections, validated through robust methods and highlighting the need for further research to understand the mechanisms and clinical applications.
Multiscale implicit frequency selective network for single‐image dehazing
Authors: Wang Zhibo , Jia Jia , Min Jeongik 
Published: September 2024

AbstractImage dehazing is aimed to reconstruct a clear latent image from a degraded image affected by haze. Although vision transformers have achieved impressive success in various computer vision tasks, the limitations in scale and quality of available datasets have hindered the transformer effectiveness for image dehazing. Thus, convolutional neural networks (CNNs) remain the mainstream approach for image dehazing, offering robust performance and adaptability. We further explore the potential of CNNs in image dehazing by proposing a multiscale implicit frequency selection network (MIFSN). The proposed MIFSN enhances multiscale representation learning based on U‐shaped networks. As hazy and clear images considerably differ in high‐frequency components, we introduce an implicit frequency selection module to amplify high‐frequency components of features and generate candidate feature maps. Implicit frequency selection attention is then used to emphasize and merge beneficial frequency components. Results from extensive experiments on synthetic and real‐world datasets demonstrate the superior performance of MIFSN for image dehazing.
