Towards Sustainable Transport: An Analysis of Urban Mobility in Hyderabad, Telangana Using Uber Movement Data
Authors: Kuchu Jayasree , Tatipamula Srinivas , Ankam Chandrakanth , Birukuri Navyashanthi
Published: February 2025

Cities worldwide face traffic congestion, challenging sustainable development and requiring insight into its dynamics, dispersion, and stability. Effective traffic management is pivotal for fostering sustainable urban mobility and enhancing quality of life. Leveraging Uber movement data, this study examines travel times and speeds across Hyderabad over a four-year span from 2016 to 2019. Congestion and friction indices from travel time matrices, along with network analysis, gauge urban accessibility, revealing similar magnitudes of Congestion and Travel Time Delay Transition Indices for inbound and outbound traffic within specific intervals. Notably, there is an inverse proportional relationship between these two indices. The Congestion Index values indicate that most zones experience significant traffic jams, while the Travel Time Delay Transition Index was calculated to affirm its inverse relationship with the Congestion Index. Employing fractal geometry, the study delves into the spatial complexity of the network and its correlation with urban growth parameters, contributing to sustainable urban planning efforts. Furthermore, the fractal dimension value obtained from the Mass-Radius method is 1.6955, with a correlation coefficient of 0.99, indicating a high degree of linearity between the road network and friction index. Results underscore the intricate interplay between traffic congestion, macroeconomic factors, and urban form, highlighting the imperative of integrating sustainability principles into transportation policies. By leveraging readily available Uber movement data, this research provides a comprehensive assessment of citywide traffic conditions, offering valuable insights for crafting sustainable transportation management strategies aimed at mitigating congestion and promoting equitable access to mobility.
Muon Mass Model - Theoretical Masses of Tau-Lepton, u- and d-quarks in Simplified Models - General Approach to Calculate Elementary Particle Masses
Authors:   Independent Researcher, Belarus, Ragin Pavel Viacheslavovich
Published: February 2025

Numerical values of masses of elementary particles are one of the most fundamental and oldest unsolved problems (the
Higgs mechanism does not explain them). In the model presented here for the first time, the theoretical mass of a “heavy
electron”, muon, is calculated as 206.7 (±2.5) electron masses, which is 100.0% (±1.2%) of the experimental value of
206.7682827(46). The result is obtained through 100 iterations of the algorithm, which uses random numbers (from
the π sequence) to represent the uncertainty of the coordinates of interacting muon substructures. Muon is considered
a structure of interconnected nodes - identical deformable balls - and contains, in contrast to a single node as a 1storder structure (and a 1st generation particle, electron) - a layer of 12 nodes surrounding it, thus forming a 2nd-order
structure, which also looks like a ball but on a smaller scale. The simplest attraction forces are modelled between the
nodes, inversely proportional to the square of the distance, in equilibrium with repulsion forces arising from a relation
analogous to the Heisenberg uncertainty formula. The energy-mass of the muon turns out to be equal to the total useful
energy released during the structure’s formation - the collapse of 13 nodes initially separated at infinity. We finish with
discussing the tauon’s, u- and d-quarks’ masses in simplified cases, showing the generality of our approach. Some
implications for future theoretical work are also given.

Effectiveness of Coffee Plant Extracts and Green Nanoparticles for Mosquito Control of the Dengue Vector Aedes aegypti: A Comprehensive Review
Authors: Abdulwahab Yousef , Al-Shmery Mohammed , Ahmad Ahyar , Wahid Isra , Taba Paulina
Published: February 2025

This comprehensive review examines the efficacy and environmental impact of coffee plant extracts and green nanoparticles as biocontrol agents for mosquitoes. Mosquitoes pose a significant public health threat by transmitting diseases such as malaria, dengue, Zika, and yellow fever. However, the use of insecticides for mosquito control raises concerns about the development of resistance and environmental and human health impacts. As an alternative, biocontrol strategies that utilize natural predators, parasites, and pathogens have gained attention. Coffee plant extracts have shown larvicidal, ovicidal, and repellent properties against mosquitoes, whereas green nanoparticles, particularly copper and silver nanoparticles, exhibit insecticidal activity. These alternatives offer advantages such as environmental friendliness, reduced resistance risks, and targeted mosquito species control while minimizing harm to non-target organisms. However, challenges exist in the mass production and distribution of biocontrol agents as well as their susceptibility to environmental factors. Ongoing research is aimed at developing more effective biocontrol agents for mosquito-borne disease prevention. This review provides valuable insights into the potential of coffee plant extracts and green nanoparticles for mosquito control, their efficacy, and the environmental considerations associated with their use.

Management of Vicharchika (Atopic Dermatitis): A Case Study
Authors: Gaikwad Ishwari Sanjay , Deshmukh Sourabh
Published: February 2025

All skin illnesses are categorized as Kushta Roga in Ayurveda. They are divided into two categories: Maha Kushta (major skin illnesses) and Kshudra Kushta (minor skin disorders). Eczema, or Atopic Dermatitis, is typified by xerosis and pruritus, featuring ill-defined patches of erythema and scaling. In its acute phase, eczema may manifest as vesicular and exudative, while the chronic phase is marked by hyperpigmentation and lichenification. Excoriations commonly occur, akin to the development of stretch marks. The clinical presentation of atopic dermatitis bears similarities to other forms of eczema, such as contact eczema, on an individual lesion level. Acute eczema is characterized by a vivid red infiltration with edema, vesicles, exudation, and crusting, whereas the subacute and chronic phases are dominated by lichenification, excoriations, papules, and nodules. The diagnostic approach incorporates factors like distribution and patient-specific characteristics. Acute eczema is precipitated by exposure to irritants or allergens, with the involvement of inflammatory mediators like prostaglandins and helper T cells. Clinical manifestations include redness, scaling, edema, exudation, crusting, and pruritus. Despite advancements in dermatology, specific treatments for eczema remain elusive in modern science, with antihistamines and topical steroids standing as the sole efficacious interventions. In the realm of Ayurveda, Shodhan and Shaman Aushadhis constitute the cornerstone of treatment for Vicharchika, aligning with a holistic approach to address both the root cause and symptoms of the condition.

Published: February 2025

The Australian Group on Antimicrobial Resistance (AGAR) performs regular period-prevalence studies to monitor changes in antimicrobial resistance in selected enteric gram-negative pathogens. From 1 January 2023 to 31 December 2023, a total of 57 hospitals across Australia participated in the Australian Gram-negative Surveillance Outcome Program (GnSOP). The 2023 survey tested 10,453 isolates, comprising Enterobacterales (9,503; 90.9%), P. aeruginosa (806; 7.7%) and Acinetobacter species (144; 1.4%), using commercial automated methods. The results were analysed using European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints (January 2024). Key resistances reported are to the third-generation cephalosporin ceftriaxone in 12.9% of Escherichia coli and in 6.9% of Klebsiella pneumoniae complex isolates. Resistance rates to ciprofloxacin were 14.5% for E. coli; 7.8% for the K. pneumoniae complex; 3.2% for the Enterobacter cloacae complex; and 7.6% for P. aeruginosa. Resistance rates to piperacillin-tazobactam were 6.0%; 9.4%; 23.3%; and 13.7% for the same four species/complexes, respectively. Thirty Enterobacterales isolates from 30 patients were shown to harbour a carbapenemase gene: ten with a blaNDM gene (blaNDM-1 [4], blaNDM-5 [4], blaNDM-7 [2]); nine with a blaOXA-48-like gene (blaOXA-244 [4], blaOXA-48 [2], blaOXA-181 [1], blaOXA-232 [1], blaOXA-484 [1]); eight with blaIMP-4; two with blaNDM-5 + a blaOXA-181-like gene; and one with blaKPC-2 + blaNDM-5 + blaOXA-181. Transmissible carbapenemase genes were also detected in two Acinetobacter baumannii complex isolates (blaOXA-23; blaOXA-23 + blaOXA-58 + blaIMP-4) and one P. aeruginosa (blaIMP-4).

This study analyses diploid and hydrostatic-pressure-induced triploid brook trout (Salvelinus fontinalis) sampled from a fish farm before (360 days post-hatch, d.p.h.) and during the normal time of sexual maturation for pan-sized market fish (555 and 667 d.p.h.). Biometric indices and slaughtering traits of examples of both ploidy levels were compared and their genomic heterozygosity and gonadal development were evaluated to assess the possible link between these two parameters and growth performance. At 555 d.p.h., triploids – irrespective of sex – had greater carcass yield than their diploid conspecifics. At 667 d.p.h., all triploids (females, males and intersex fish) were significantly larger and heavier and had far lower gonadosomatic indices than their diploid conspecifics; however, in terms of carcass and fillet yields these differences were not as notable. Delayed gonadal growth in triploids was confirmed. Microsatellite analysis at five polymorphic loci suggest that triploids could have higher levels of heterozygosity than their diploid counterparts, a trend in multilocus heterozygosity that was consistent in all three age groups. Nevertheless, the link between heterozygosity and body weight was inconclusive. Suppressed gonadal development seems to be more probable explanation for the improved growth performance of triploids. Remarkable occurrence of intersex fish in triploids at both 555 and 667 d.p.h suggests that intersexes can commonly arise from artificial triploidization in brook trout. External appearance, biometric indices and slaughtering traits of triploid intersex were highly similar to that of triploid females.

The structure of loess is an important physical property indicator. Just like grain size, moisture content and density, it also affects the physical and mechanical properties of loess. Based on the definition of the constitutive degree index, the definition of structural parameters was redefined. And conventional triaxial shear tests were conducted on undisturbed soil samples and remolded soil samples with different moisture contents and different dry densities. Firstly, the deformation characteristics and strength changes of the soil samples were analyzed. Then, based on the definition of structural parameters, the structural change laws of the soil were analyzed. Finally, the relationships between the structural properties and soil moisture, grain size and density were analyzed, thereby verifying that the newly proposed definitions of the structural parameters are reasonable.
Neuron-to-glia and glia-to-glia signaling directs critical period experience-dependent synapse pruning
Authors: Nelson Nichalas , Miller Vanessa , Broadie Kendal
Published: February 2025

Experience-dependent glial synapse pruning plays a pivotal role in sculpting brain circuit connectivity during early-life critical periods of development. Recent advances suggest a layered cascade of intercellular communication between neurons and glial phagocytes orchestrates this precise, targeted synapse elimination. We focus here on studies from the powerful Drosophila forward genetic model, with reference to complementary findings from mouse work. We present both neuron-to-glia and glia-to-glia intercellular signaling pathways directing experience-dependent glial synapse pruning. We discuss a putative hierarchy of secreted long-distance cues and cell surface short-distance cues that act to sequentially orchestrate glia activation, infiltration, target recognition, engulfment, and then phagocytosis for synapse pruning. Ligand-receptor partners mediating these stages in different contexts are discussed from recent Drosophila and mouse studies. Signaling cues include phospholipids, small neurotransmitters, insulin-like peptides, and proteins. Conserved receptors for these ligands are discussed, together with mechanisms where the receptor identity remains unknown. Potential mechanisms are proposed for the tight temporal-restriction of heightened experience-dependent glial synapse elimination during early-life critical periods, as well as potential means to re-open such plasticity at maturity.

For successful colonization, pathogenic bacteria need to adapt their metabolism and virulence functions to challenging environments within their mammalian hosts that are frequently characterized by low oxygen (O2) tensions. Upon oral ingestion, the human pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium) is exposed to changing O2 and pH levels. Low concentrations of O2, which can enhance the virulence of enteroinvasive pathogens, facilitate the expression of the type three secretion system (T3SS-1) encoded by the Salmonella pathogenicity island 1 (SPI-1) that is critical for enteroinvasion and pathogenicity of S. Typhimurium. To study the impact of key environmental cues of the intestine when Salmonella encounter enterocytes, we established an in vitro growth model, which allows shifting the concentration of O2 from 0.5% to 11% and the pH from 5.9 to 7.4 in the presence of acetate and the alternative electron acceptor nitrate. Compared to normoxia, hypoxia elevated the expression of SPI-1 genes encoding T3SS-1 translocators and effectors, which resulted in higher invasion and effector translocation in epithelial cells. While hypoxia and pH shift only marginally altered the gene expression of SPI-1 regulators, including the SPI-1 repressor hilE, hypoxia and pH shift completely incapacitated HilE in a post-translational manner, ultimately promoting SPI-1 activity. From these findings, we conclude that O2-dependent HilE function allows for ultrasensitive adaptation of SPI-1 activity in environments with varying O2 availability such as the intestinal tract.
Ischemia with no obstructed coronary arteries and microvascular testing procedures: a review of utility, pharmacotherapy, and current challenges

Ischemia with no obstructive coronary arteries (INOCA) is an increasingly recognized condition in patients presenting with angina and positive stress tests but without significant coronary artery stenosis. This review addresses the pathophysiology, diagnostic approaches, and management strategies associated with INOCA, emphasizing epicardial coronary spasms and coronary microvascular dysfunction (CMD) as underlying mechanisms and myocardial bridging (MB) as a risk factor. Diagnostic modalities include both non-invasive techniques and invasive procedures, such as acetylcholine provocation testing, to differentiate vasospasm from microvascular causes. The paper discusses a potential interference between vasodilators used in trans-radial access and coronary spasm testing. Long-term management approaches for INOCA patients, including pharmacologic therapies and lifestyle interventions, are reviewed.

Published: February 2025

Purpose

Abdominal aortic calcification (AAC) is related to inflammation and nutritional status. The Naples prognostic score (NPS) is an innovative biological marker capable of reflecting systemic inflammation and nutritional status. This research seeks to investigate the correlation of NPS with severe abdominal aortic calcification (SAAC).

Methods

The research evaluated data obtained from the National Health and Nutrition Examination Survey (NHANES) conducted between 2013 and 2014. The variables were filtered utilizing the Least Absolute Shrinkage and Selection Operator (LASSO) regression. Weighted logistic regression models were employed to examine the association of NPS with SAAC. The predictive value of NPS for the risk of SAAC was assessed utilizing the receiver operating characteristic (ROC) curve. A subgroup analysis was conducted to assess the strength and reliability of the research findings.

Results

The research encompassed 2,854 participants, among whom 303 (11.87%) exhibited SAAC. The outcomes of multivariate weighted logistic regression revealed that participants with a NPS of 3–4 points was positively correlated with SAAC in comparison to the control group [odds ratio (OR) = 2.07, 95% confidence interval (95%CI): 1.17–3.67]. The area under the curve (AUC) for predicting the risk of SAAC using NPS was 0.635. The subgroup analysis results indicated that there was no significant difference noted in the association of NPS with SAAC across various population subgroups.

Conclusion

A positive association of NPS with SAAC has been observed in this research. This study offers valuable insights into the prevention and diagnosis of SAAC. Future longitudinal studies are warranted to confirm causative relationships and assess the role of NPS in clinical decision-making for SAAC.
Acceptance of a mental health app (JoyPopTM) for postsecondary students: a prospective evaluation using the UTAUT2

Published: February 2025

Introduction

Mental health (MH) smartphone applications (MH apps) can support the increasing MH needs of postsecondary students and mitigate barriers to accessing support. Evaluating MH app acceptance using technology acceptance models is recommended to improve student engagement with MH apps. The JoyPopTM app was designed to improve youth resilience and emotion regulation. The JoyPopTM app is associated with improved student MH, but its acceptance has yet to be evaluated quantitatively. The present study used the Unified Theory of Acceptance and Use of Technology (UTAUT2) to evaluate and examine constructs and moderators influencing the acceptance (i.e., behavioural intention) and use of the JoyPopTM app.

Method

Participants were 183 postsecondary students attending a Canadian University who used the app for one week and completed measures before and after using the app. Relationships posited by the UTAUT2 were tested using partial least squares structural equation modelling (PLS-SEM).

Results

Most participants accepted the JoyPopTM app. The UTAUT2 model explained substantial variance in behavioural intention and app use. Performance expectancy, hedonic motivation, and facilitating conditions predicted behavioural intention, and behavioural intention and facilitating conditions predicted app use. Age moderated the association between facilitating conditions and behavioural intention. Experience moderated the relationship between performance expectancy, hedonic motivation, and social influence on behavioural intention.

Discussion

Results provide insight into factors influencing the acceptance of the JoyPopTM app and its ability to engage students. Results also provide valuable insights for evaluating and optimally designing MH apps.
