Perceptual binding occurs independently beyond early neural adaptation stages in human color cone pathways
Authors: Matias Francisca C. , Castelhano João , Castelo-Branco Miguel 
Published: September 2023

Abstract
Color perception entails competing temporal context mechanisms such as adaptation versus memory persistence1. Perceptual dynamics in color cone pathways can be studied using the phenomenon of hysteresis, well-known in the framework of physical dynamical systems. It postulates analogous mechanisms: a) visual persistence defining positive hysteresis b) adaptation or habituation (negative hysteresis). Adaptation causes early perceptual switches to competing states. We investigated competition between these mechanisms in human color cone pathways. Color adaptation occurs within early visual pathways up to V4, involved in local scene analysis, but it is unknown if they underlie global perceptual binding of visual elements2. We tested if the neural locus of perceptual binding occurs at visual and memory stages beyond the locus of color adaptation, using a dynamic color matching task in cone contrast space, along Blue-Yellow (S-(L + M) and Green-Red processing channels (L-M). Simple vs Compound stimuli required or not holistic perceptual binding, under visual or memory-guided conditions. Adaptation (negative hysteresis) dominated for the former condition, was stored in memory, but vanished when binding was required either in vision or memory. In sum, cone pathway adaptation mechanisms dominate in early vision, while perceptual binding occurs at a second stage as predicted by the feature integration theory.
Study on damage evaluation using cavitation-bubble collapsing time
Authors: Kawashima Hiroyuki , Kogawa Hiroyuki , Tanaka Nobuatsu , Futakawa Masatoshi 
Published: September 2023

Abstract
Cavitation bubbles grow and collapse due to impulsive pressure change in liquids and the damage could be imposed on the interfaces between liquid and solid walls. Liquid heavy metals are applied as high-intensity spallation neutron sources, e.g., mercury targets in SNS (spallation neutron source in ORNL) and MLF/J-PARC, etc. The cavitation damage gets to be one of crucial issues from the viewpoint of structural integrity, i.e., durability under high power operation. The relationship between the dynamic behavior of cavitation bubbles and the local impact which generated at the cavitation collapse and causes the damage was systematically investigated using the direct visualization technique with a high-speed camera and electric spark thermal loading technique under water as comparing with the numerical simulation based on the Keller-Miksis equation. The results show a linear correlation between the impact energy of cavitation bubble collapse and the volume change of the bubble. In addition, this volume change can be evaluated from the collapsing time of the cavitation bubble. The collapsing time furthermore can be derived from the cavitation bubble development time using the simplified equation, and the local impact and damage due to cavitation collapse can be qualitatively estimated from bubble collapsing time.

Published: September 2023

Abstract
With Jacobi Elliptic Functions (JEF) we obtain soliton solutions of wave motion in lattices composed of particles interacting by nonlinear forces. The interaction in lattices is between the nearest-neighbors with realistic Morse potential gaps. This yields soliton solutions both in continuum and discrete lattices as depicted.
Patterns of childhood cancer mortality in Hungary since the turn of the millennium, including the two years of the COVID-19 pandemic
Authors: Németh Kristóf , Nyári Tibor András , Lantos Tamás 
Published: September 2023

Abstract
Background: During the COVID-19 period health care had to be cut back which may also have affected the numbers and patterns of childhood cancer deaths in Hungary. We aimed to analyse the pattern of childhood cancer mortality among children under 15 years in Hungary. Death rates were compared during the periods 2020–2021 (pandemic) and 2001–2019 (non-pandemic). In addition, cyclical trends were examined.
Methods: Mortality data were obtained from the nationwide population register. Monthly deaths were investigated using Walter–Elwood and Poisson regression methods.
Results: Overall, 14,931 childhood deaths (1,092 from cancers) were registered between 2001-2021. The cancer mortality risk was significantly higher among boys than girls. Furthermore, this risk was significantly lower in older age groups (5–14 years) than in the under-5 group (IRR = 0.816; 95% CI: 0.756–0.879; p < 0.001). A significantly decreasing trend was detected for yearly childhood cancer mortality rates with an annual IRR of 0.976 (95% CI: 0.966–0.986; p < 0.001). This tendency was not influenced by the pandemic. However, different patterns of seasonal variation were revealed in childhood cancer mortality rates during 2020–2021 and 2001–2019.
Conclusions: Although the annual trend in childhood cancer mortality was not affected by
the coronavirus pandemic, there was a significant change in the pattern of childhood cancer mortality during the pandemic and non-pandemic period in Hungary. The seasonal variation of monthly childhood cancer mortality rates suggests that environmental factors play an important role in the aetiology of childhood cancer deaths.

Published: September 2023

Abstract
Data on the interactions between the order Psittaciformes and the anthropogenic environment are still insufficient and have not been systematized, especially in the Neotropical region. This is despite the fact that cities are the everyday territory shared by these birds and the vast majority of those of us who study them. As a consequence of this coexistence, the volume of accumulated knowledge is probably significantly greater than the formal scientific contributions on the subject. In this survey, information was compiled on the wild parrots inhabiting cities in the Southern Cone of South America, based on surveys with key informants. The results obtained highlighted the presence of a large number of parrots species that form part of the urban avifauna of the region, between 67% to 90% of the total number of species of the order cited for each territory evaluated. The greatest species richness and the number of breeding species was associated with the large cities located in middle and low latitudes. We confirmed breeding within the cities for more than 40% of the species mentioned. Seventy-five per cent of the species reported are native to the study area, the rest originating from other regions of South America or other continents. Quarter of the reported species are considered threatened and almost 50% have declining populations. Urban parrots represent a challenge in the search for urban models compatible with biodiversity conservation, in the designing of innovative conservation strategies that respond to the new challenges posed by a constantly growing human population.

Published: September 2023

Abstract
Global warming leads to changes in distribution of species across the globe. Himalayan altitudinal gradients are one of the most susceptible ecosystems to varying climatic drivers and predicting distribution of species on this rugged topography in future climate seeks attention in terms of both ecological and economic importance. Western Himalayan states of Himachal Pradesh and Uttarakhand shelter one-tenth of world’s known higher-altitude plant species. Rhododendron arboreum, the most widely distributed tree in Himalayas, was studied for its distribution in future climate. Ensemble models were employed to predict distribution by 2070 in Representative Concentration Pathways (RCP) 4.5 and RCP 6.0 scenarios. Altitudinal shift was studied by incorporating spatial measures, considering minimum horizontal distance the species can move. Centroidal shift was estimated in terms of both direction and magnitude, and altitudinal analysis was performed at centroidal shift. Results showed that, Himalayan locations in RCP 4.5 scenario would get warmer than RCP 6.0 scenario, and species is just as likely to shift upwards (higher elevations in RCP 4.5 scenario) as downward (lower elevations in RCP 6.0 scenario) despite consistent warming across the study area. Highest suitable elevation range for the species presence is likely to be ~ 2100m in current scenario, 2200m – 2400m in RCP 4.5 scenario, and 1800m – 2100m in RCP 6.0 scenario. Temperate zone of Himalayas may turn out as the most suitable zone for R. arboreum and species is likely to move in Northwest direction with a horizontal distance of 60km and 25km in RCP 4.5 and RCP 6.0 scenarios, respectively.
Dimensional Considerations in the Evaluation and Design of Energy Dissipaters
Authors: Rakhio Allah 
Published: September 2023

Abstract
This paper presents an experimental and simulation-based investigation into the force characteristics of rubber ball-based energy dissipaters. The study focuses on exploring the dimensional considerations in energy dissipation, where rubber balls serve as a medium to control vibrations. The paper scrutinizes the force properties through various approaches, including filling ratio, rotor speed, dissipater dimensions, and ball size. The results indicate that the size of the rubber balls significantly improves the performance of the energy dissipater, suggesting that larger balls enhance its effectiveness. Additionally, enhancing the filling ratio and the dimensions of the energy dissipater results in greater force. To supplement the experimental findings, a numerical simulation technique based on the discrete element analysis method is employed for an exhaustive quantitative and qualitative analysis of the energy dissipater. The close correlation observed between the experimental and simulation results confirms the accuracy of the proposed model, especially for large-scale energy dissipation systems.
Modeling customer portfolios in competitive B2B service markets to evaluate the relationship between loyalty and customer attractiveness
Authors: Tsai Ming‑Chih , Merkert Rico , Wu Andy 
Published: September 2023

Abstract
In competitive B2B service markets, customer loyalty may be a necessary but not sufficient condition for achieving firm profitability. Assuming this, we design a portfolio analysis approach with a novel four-quadrant taxonomy to evaluate the relationship between loyalty and customer attractiveness. Employing an attractiveness matrix and stepwise stratification analysis, we evaluate 158,639 transactions associated with 616 business customers of a Taiwanese global freight forwarder. Our results indicate that in this competitive B2B service market, customers in the “pure loyalty” and “profitable disloyalty” segments accounted for 6% and 19% of customers, respectively. Customers with “pure loyalty” supported long-term profits through relational attractiveness, and those with “profitable disloyalty” supported short-term profits through transactional attractiveness. The largest group of customers (34%) exhibited “spurious loyalty” with low transactional value, and they are therefore less attractive from a firm value generation perspective. As traditional customer classification methods suffer from time lags and do not account for competition effects, our approach (using short-term observations around attractiveness and profitable loyalty) offers service suppliers aiming to enhance their profitability a tool to quickly identify segment customer portfolios and reveal distinctive characteristics of “golden customers”.
An Improved Multi innovation Adaptive Robust Dual Kalman Filter Algorithm for Estimating Battery State
Authors: guan zhe , Yang FaZhi , Yu Taohua , An AiMing 
Published: September 2023

Abstract
In response to the inaccurate estimation of State of Charge (SOC) in current power battery management systems, and considering that SOC may be subject to offset constraints from State of Health (SOH) when estimated separately. A method combining adaptive robust Kalman filtering with multiple innovation theories and online identification of dual Kalman filtering parameters is proposed. This control method is based on adaptive robust Kalman control. It corrects the estimated values using multiple innovation values and Kalman gains at different times. Dual Kalman filtering is used for online parameter identification and joint estimation of battery health status, which increases the amount of error information and provides an optimized method for accurate estimation of SOC and SOH. To verify the rationality of the algorithm, a second-order RC equivalent circuit model is used to characterize the dynamic characteristics of the battery, and experimental verification is carried out under different operating conditions. The experimental results show that the average error of SOC under three operating conditions: UDDS, FUDS, and US06 is 0.56\%, 0.31\%, and 1.23\%, respectively. The estimated error of SOH after stabilization is less than 1.73\%. The estimation error is the lowest among the five estimation algorithms. The proposed algorithm has been verified to have good accuracy and convergence. The multi-innovation adaptive robust dual Kalman filtering algorithm provides a theoretical basis for accurate state estimation and widespread application of lithium batteries.
Quark stars in the pure pseudo-Wigner phase

Published: September 2023

Abstract
In this paper, we take a different scenario of a pure quark star which is completely composed of quarks in the pseudo-Wigner phase. The equation of state (EOS) of deconfined quark stars is studied in the framework of the two-flavor NJL model, and the self-consistent mean field approximation is employed by introducing a parameter α combining the original Lagrangian and the Fierz-transformed Lagrangian, LR = (1 − α)L + αLF, to measure the weights of different interaction channels. We assume deconfinement phase transition happens along with the chiral phase transition. Thus, due to the lack of description of confinement in the NJL model, the vacuum pressure is set to confine quarks at low densities, which is the pressure corresponding to the critical point of chiral phase transition. We find that deconfined quark stars can reach over two-solar-mass, and the bag constant therefore shifts from (130 MeV)4 to (150 MeV)4 as α grows. In addition, the tidal deformability Λ is found to range from 253 to 482 along with the decrease of α, which satisfies the astronomical constraint of Λ < 800 for 1.4-solar-mass neutron stars.

Published: September 2023

Abstract
The heat shielding and thermal stability capability of ceramic fillers brings it to the forefront for utilisation in polymer composites for thermally variable applications. The present work focusses to study the physical, mechanical and thermal behaviour of ceramic filler (SiC) in glass fiber reinforced hybrid polymer composites. During the investigation, different weight percentages of SiC filler (0–40 with step of 5) was added with glass fiber epoxy composites. The tensile, flexural, impact strength, hardness of both types of the composites were determined. The experimental results indicate varied rate of deterioration of tensile and flexural strength of the hybrid composites with respect to the SiC filler content. However, the impact strength and hardness of the composites enhanced due to the incorporation of SiC ceramic fillers. Further thermogravimetric analysis and thermal conductivity test was performed to study the effect of ceramic filler and glass fiber on the thermal behaviour of the developed composites. The experimental thermal conductivity values of composites were compared with those of analytical models. The inclusion of SiC ceramic filler enhanced the thermal stability and conductivity of epoxy-based composites. However, the hybridization of SiC filler with glass fiber further improved the thermal properties of the composites. The microscopic analysis of the developed composites was carried out to ascertain deformation mechanisms of under tensile, flexural and impact loading.

Abstract
Introduction:
People who inject drugs (PWIDs) living with HIV face high levels of stigma, violence, and rape due to their risky lifestyles, potentially facilitating the spread of HIV. This study assessed the level and type of stigma and violence among PWIDs attending Heartland Alliance in Akwa Ibom State and their coping mechanisms.
Methods
This descriptive cross-sectional study of 442 PWIDs receiving care at four one-stop shops in the state was conducted using mixed methods. Quantitative data were collected through pretested structured questionnaires and an adopted stigma scale, administered by trained research assistants using Computer Assisted Personal Interviewer (CAPI). For qualitative data, one focus group discussion (FGD) was held at each site with 8–10 purposively selected PWIDs, and transcripts were analysed thematically.
Results
Most respondents were male (78%) with a mean age of 32.7 ± 7 years. Pentazocine use was common (52%), and 18% shared needles, with 15% sharing blood after injections among friends. More than half (58%) missed more than one dose of ARVs in the past week. Perceived stigma (59%) was more common than internal stigma (18%), with predictors being student status, non-disclosure of HIV status, and non-adherence to treatment. PWIDs Physical violence (47.5%) and verbal abuse (37.1%) were prevalent among PWIDs. Female PWIDs had a ninefold higher risk of rape. Coping mechanisms included isolation, increased substance use, battle readiness, and positive reframing.
Conclusion
PWIDs face significant levels of stigma, violence, and non-adherence, jeopardising treatment outcomes and perpetuating STI, HIV, and blood-borne infection transmission. Establishing harm-reduction programs is essential to address these vulnerabilities and the consequences associated with drug use.
On the linear structure of the interlaced Alfvén vortices in the tail of Uranus at solstice.
Authors: Pantellini Filippo 
Published: September 2023

Abstract

Incompressible vortex flow are observed in a large variety of astrophysical plasmas such as the convection zone and the atmosphere of stars, in astrophysical jets in stellar winds and in planetary magnetospheres. More specifically, magnetohydrodynamic (MHD) simulations have shown that two large scale interlaced Alfvénic vortices structure the magnetic tail of Uranus at solstice time. Assuming identical vortices, we compute the general linear structure of the flow near their centers within the frame of ideal MHD. We then use the analytic results to interpret and qualify the vortices observed in a 3D MHD simulation of a fast rotating Uranus-type planet.

Published: September 2023

Abstract
This paper presents an enhanced framework that combines Symbolic Genetic Algorithm (SGA) with Long-Short Term Memory Neural Network (LSTM) for predicting cross-sectional price returns using fundamental indicators of 4,500 listed stocks in China. The study addresses the challenges posed by fundamental indicators resembling smart beta factors in efficient markets and the low frequency of fundamental indicator updates for deep learning models (DNN). The proposed DNN framework incorporates data augmentation and feature selection techniques, resulting in significant improvements in Rank Information coefficient (Rank IC) and IC information ratio (ICIR) by 1,128% and 5,360% for fundamental driven data. Additionally, a rule-based strategy based on the hybrid SGA-LSTM model outperforms major Chinese stock indexes, generating impressive average annualized excess returns compared to the CSI 300 and CSI 500 indexes. These findings highlight the effectiveness of LSTM with SGA in optimizing cross-sectional stock return predictions based on fundamental indicators, providing valuable insights for financial professionals..
Comparative anuran diversity and abundance in sprayed and unsprayed transplanted rice crop fields
Authors: SINGH SHELLY , SINGH RAJWINDER 
Published: September 2023

Abstract
Agriculture intensification and management practises is a significant threat to biodiversity. However, changed habitats such as irrigated rice fields could offer as potential refuges for some anurans species. This study examined diversity and abundance of anurans in transplanted rice crop fields under sprayed and unsprayed conditions. Six anuran species were recorded from transplanted rice crop fields (D. melanostictus, D. stomaticus, E. cyanophlyctis, E. adolfi, F. limnocharisi and H. tigerinus) with patchy occurrence of E. adolfi. However, 36.03–37.93% increase in anuran population was recorded in unsprayed as compared to sprayed transplanted rice crop fields. Total mean population in unsprayed fields was 37.05% higher as compared to sprayed fields. Increase in body weight of males (2.96–14.21%) was more than females (3.87–11.17%) in unsprayed than sprayed fields.A positive correlation was found between amphibian population with atmospheric temperature (˚C), mean relative humidity (%), rainfall (mm), soil pH, soil OC except for soil EC. The study suggests rice agroecosystems, in partnership with neighboring natural aquatic and terrestrial habitats with no use of pesticides can serve as a sanctuary for anuran biodiversity.
