Abstract
Polycystic ovary syndrome (PCOS) is a ubiquitous reproductive condition with triggering hallmarks such as glucose intolerance, hyperandrogenism, and dyslipidemia. Despite the existence of various PCOS animal models, an ideal model which could encompass all PCOS-specific phenotype is of dire need. Dehydroepiandrosterone (DHEA) induced PCOS rats are frequently employed; though, determining the superior model among pubertal and prepubertal rats, incorporation of high fat diet (HFD), and their sustainability remains uncertain. This study aims to examine the age factor, impact of HFD, and DHEA regimen in model development. Prepubertal and pubertal Sprague–Dawley rats were subcutaneously injected with DHEA (6 mg/kg and 60 mg/kg/day, respectively) with and without HFD up to 21 days. Serum testosterone, glucose, lipid profile, ovary morphology, and estrous cycle were evaluated. Following 21 days of treatment with DHEA, pubertal PCOS rats exhibited better reproductive phenotype than prepubertal rats. However, there was no significant difference in the lipid profile. Accordingly, both the age-group rats were concomitantly treated with DHEA and HFD for additional 3 weeks on alternate day basis after model development. The persistence of reproductive and metabolic features on treatment withdrawal were also simultaneously investigated by alienating the rats into continuous and stop dosing groups. The DHEA + HFD and DHEA treated pubertal rats in continuous dosing group showed significant PCOS features (p < 0.05) compared to stop dosing, prepubertal, and control groups. To conclude, continual dosing with DHEA on alternate days for 3 weeks is necessary to sustain metabolic and reproductive phenotypes of PCOS.

AbstractIncreasing of plastic waste threatening ecosystems globally, this experimental work investigates recycled plastics as sustainable aggregate replacements in pervious concrete. Pervious concrete allows water passage but has installation/maintenance difficulty due to high weight. This research addresses the lack of eco-friendly lightweight pervious solutions by assessing physical and mechanical performance of mixes with 100% recycled plastic and traditional aggregate percentages. Density reduced 12% using a 100% plastic aggregate mix, achieving 1358 kg/m3 with compressive strength of 3.92 MPa, adequate for non-structural applications. A 7.8% decrease in water absorption versus conventional pervious concrete signifies retained porosity and permeability despite the plastic aggregates. Though early material limitations increase costs over 199.32%, recycled plastics show viability as effective, sustainable substitutes for natural aggregates in lightweight pervious concrete. With further availability and affordability improvements, these recyclable mixes can enable significantly greener construction practices. Findings provide key insights on balancing structural requirements, eco-friendliness and water infiltration capacity in plastic-based lightweight pervious concrete for broader adoption. The research examines the mechanical and durability characteristics of Light-Weight Pervious Concrete (LWPC) composed entirely of plastic aggregate. It also investigates the economic viability and potential for sustainable urban applications. The cost assessment reveals long-term environmental advantages, even though the initial expenses are higher. Additionally, the study considers an eco-friendly approach that combines plant growth with pervious concrete to promote greater sustainability.
Understanding happiness and academic procrastination among professional students
Authors: Rasool Insha , Ganai M. Y. , Dar Mohammad Amin 
Published: November 2024

AbstractThis study examines the role of happiness in academic procrastination among professional students and explores the impact of student type (senior vs. junior) and residence (rural vs. urban) on procrastination behaviors. The sample consisted of 896 professional undergraduate students selected using a stratified sampling technique, with 481 (54%) classified as seniors and 415 (46%) as juniors. Data were collected through a structured questionnaire and analyzed using multivariate analysis of variance (MANOVA) and regression analysis. The research reveals that happiness explains 40% of the variance in academic procrastination, underscoring its significant influence. The findings show that while student type affects procrastination levels, it does not significantly impact happiness. Residence and the interaction between student type and residence have negligible effects on both happiness and procrastination. These results suggest that emotional well-being is a crucial factor in mitigating procrastination, with happiness playing a more substantial role than demographic factors such as seniority and geographical location. The significance of this study lies in its challenge to traditional views that emphasize demographic characteristics in educational interventions. By demonstrating the critical role of happiness in reducing procrastination, the study highlights the importance of focusing on emotional well-being to enhance academic performance. The premise is that internal emotional factors, rather than external demographics, have a greater impact on procrastination behaviors, suggesting that fostering happiness among students could be a more effective strategy in addressing academic procrastination.
Numerical framework for the development of atmosphere-breathing electric propulsion for Earth and Mars atmosphere
Authors: Pessina Valentina , Smirnova Maria , Schein Jochen 
Published: November 2024

AbstractAtmosphere-breathing electric propulsion systems provide a competitive advantage for the lower orbit altitudes since the propellant is collected directly from the atmosphere. The effectiveness of this technology depends on crucial aspects such as the collection and compression performance characterization, as well as the drag estimation and compensation. In the first part of this study, the lower Mars and Earth atmospheric characterization is derived based on current models and mission data. This characterization is a reliable dataset for the boundary conditions for the simulations carried out in the second part of this study. The proposed computational framework based on the Direct Simulation Monte Carlo method aims to investigate the collection and compression performances and to estimate the drag. The numerical comparison with a literature case validates the numerical setup presented in this study. The effect of different gas-surface interaction models is investigated by comparing the results yielded by the Maxwellian model (fully specular and partially diffuse reflection) and the Cercignani-Lampis-Lord model. Since the intermolecular collisions can become more relevant at the inlet of the ionization stage, both the variable hard and variable soft sphere models are briefly examined, as well as the inclusion of gas-phase reactions. Finally, the simulation results of the two cases for the low Mars orbit (150 and 140 km) are compared to the Earth case (180 km).
Inequality Challenged and Restored
Authors: Ericsson Peter , Winton Patrik 
Published: November 2024

In the 1710s, under pressure from an ongoing war, Sweden’s absolute king, Charles XII, implemented a number of fiscal and monetary measures that displayed a disdain for traditional privileges and carried a potential for social change. Taxation was made progressive and credit became more important to finance the war. Liquidity was radically expanded, most significantly by the release of very large amounts of fiat coins. Following the death of Charles XII in November 1718, there was a political reaction against the war policies and the fiscal and monetary measures were reversed, resulting in the dismantling of royal absolutism and a partial government default. This study consists of two parts. In the first, we investigate the impact of the war policy and the monetary measures of Charles XII’s regime on the social redistribution of resources in Swedish society, especially in the years 1715 to 1718. In the second, we focus on how the socioeconomic changes were addressed by political agents between the death of Charles XII and the default of 1719. Our results show that the fiat money permeated the economy and reached all social groups, and that in some locations its distribution upset the prevailing social order. Peasants and other low-ranking groups were targeted by the partial default, which largely deprived them of their monetary assets.
Irrational rotations and

Abstract
We study a skew product transformation associated to an irrational rotation of the circle

$[0,1]/\sim $

. This skew product keeps track of the number of times an orbit of the rotation lands in the two complementary intervals of

$\{0,1/2\}$

in the circle. We show that under certain conditions on the continued fraction expansion of the irrational number defining the rotation, the skew product transformation has certain dense orbits. This is in spite of the presence of numerous non-dense orbits. We use this to construct laminations on infinite type surfaces with exotic properties. In particular, we show that for every infinite type surface with an isolated planar end, there is an infinite clique of

$2$

-filling rays based at that end. These

$2$

-filling rays are relevant to Bavard and Walker’s loop graphs.
In the Name of Integrity? Anticorruption Discourse of Brazilian Operation Lava Jato
Authors: Grangeia Mario Luis , Thijm Joris Alberdingk 
Published: November 2024

Abstract
This article identifies four frames of corruption in the discourse of three leaders of Operation Lava Jato, also known in English as Operation Car Wash, a large-scale Brazilian anticorruption operation (2014–2021). These frames are inequality, hidden pact, backwardness, and chronic disease. The frames were identified by analyzing a wide set of press interviews, opinion articles, and books by two prosecutors and one judge whose work has revealed scandals involving the state oil company Petrobras. The operation had a major impact on politics and the economy and left a controversial legacy. We noticed a contradiction between one frame invoking judicial activism (inequality) and three frames focusing on specific techniques that appeal to a more conventional view on the judiciary’s role (hidden pact, backwardness, and chronic disease). Furthermore, even when scholars were still largely positive about the operation, the discourse showed signs of judicial activism. This analysis contributes to the debate on Lava Jato and judicial activism by focusing on discourse rather than action.

AbstractUnderstanding the water use of drought-tolerant crops of the drought-prone Mediterranean regions is important for sustainable agriculture. The aim of this study was to evaluate the yield and yield responses of amaranth (Amaranthus hybridus L.) to different irrigation strategies conducted in 2019 and 2020 under Mediterranean climatic conditions using surface drip (SD) and subsurface drip (SSD) systems. Strategies investigated were: regulated deficit irrigation (RDI), conventional deficit irrigation (DI25, DI50, DI75), full irrigation (FI) and rainfed treatment. The highest grain yield was observed in FI treatments; RDI treatments produced 5% lower grain yield than the FI treatments, although the RDI treatments resulted in water savings of 23 and 21% for SD and SSD systems, respectively. DI treatments resulted in lower leaf water potential (LWP) and higher crop water-stress index (CWSI) compared to FI in both systems values. The results showed that optimum irrigation conditions to obtain the highest amaranth grain yields were associated with an LWP of −1.0 MPa and an average CWSI of about 0.25. The FI treatments under SSD systems had the highest grain production, followed by FI under SD and RDI under both the drip systems. Under SD and SSD systems, RDI saved 23 and 21% water, respectively, and produced a yield statistically comparable to that of FI. The SSD methods generated higher net income than SD. From these results it can be concluded that both RDI and DI75 could be a good alternative to FI under the conditions of water scarcity in the Mediterranean region.

AbstractA growth monitoring study (0–7 day of age) was conducted involving 87, one-day old Ross 308 male broilers to evaluate organ weights, bone parameters and ileal transcriptomic profile of broiler chicks as influenced by day 7 bodyweight (BW) grouping. The chicks were raised in a deep-litter house under common controlled environmental conditions and commercial starter diet. Chicks were grouped on day 7 into two distinct BW, super performer (SP) and under performer (UP) with bodyweights >260, and <200 g respectively. Results revealed that the SP chicks had significantly higher bone ash, sodium (Na), phosphorus (P) and rubidium (Rb) concentrations compared to the UP chicks on D7. In contrast, the UP chicks had significantly higher tibial cadmium (Cd), caesium (Cs) and lead (Pb) compared to the SP group; the UP chicks also had proportionally heavier relative gizzard weight than the SP chicks. The ileal transcriptomic data revealed differentially expressed genes (DEG) between the two groups of chicks, with 150 upregulated and 83 down-regulated genes with a fold change of ≥1.25 or ≤ 1.25 in the SP chicks relative to the UP chicks. Furthermore, functional annotation and pathway analysis revealed that some of these DEG were involved in various pathways including calcium signalling, Wnt signalling, cytokine-cytokine receptor interaction and mucin type O-glycan biosynthesis. This study revealed that chicks of the same breed and of uniform environmental and diet management exhibited differences in digestive organ weights, tibial bone characteristics and ileal gene expression that may be related to BW.

Abstract
Clinostomids are a group of digeneans in which substantial diversity has been recently discovered, with some metacercariae specific to their fish hosts. Genetic analysis has been instrumental in elucidating species diversity within this genus. Recently, seven COI lineages were reported in Argentina, along with three metacercarial morphotypes lacking molecular data. Two of these were found parasitising Rivulidae fishes. The discovery of Clinostomum metacercariae in Trigonectes aplocheiloides and Titanolebias monstrosus from temporary ponds in the western Chacoan region allowed us to redescribe the metacercariae previously identified by other authors and provide the first sequences of this lineage. The morphology of the metacercariae in both hosts matched previously reported descriptions. Genetic analysis clustered the new lineage with Clinostomum detruncatum, Clinostomum sp. 7, Clinostomum L1, and Clinostomum CRA. This discovery leaves only two morphological records of metacercariae to be characterised using DNA sequencing: one in another Rivulidae (Neofundulus paraguayensis) and one in a Loricaridae (Hypostomus sp.). The present results represent the eighth clinostomid lineage sequenced from Argentina, highlighting the extensive diversity in South America and the many lineages yet to be described or identified, considering that only one of these lineages is formally described based on adult specimens found in the heron Ardea cocoi.
Balanced Multi-UAV path planning for persistent monitoring
Authors: Zhan Xinru , Chen Yang , Chen Xi , Zhang Wenhao 
Published: November 2024

Abstract
In scenarios such as environmental data collection and traffic monitoring, timely responses to real-time situations are facilitated by persistently accessing nodes with revisiting constraints using unmanned aerial vehicles (UAVs). However, imbalanced task allocation may pose risks to the safety of UAVs and potentially lead to failures in monitoring tasks. For instance, continuous visits to nodes without replenishment may damage UAV batteries, while delays in recharging could result in missing task deadlines, ultimately causing task failures. Therefore, this study investigates the problem of achieving balanced multi-UAV path planning for persistent monitoring tasks, which has not been previously researched according to the authors’ knowledge. The main contribution of this study is the proposal of two novel indicators to assist in balancing task allocation regarding multi-UAV path planning for persistent monitoring. One of the indicators is namely the waiting factor, which reflects the urgency of a task node waiting to be accessed, and the other is the difficulty level which is introduced to measure the difficulty of tasks undertaken by a UAV. By minimizing differences in difficulty level among UAVs, we can ensure equilibrium in task allocation. For a single UAV, the ant colony initialized genetic algorithm (ACIGA) has been proposed to plan its path and obtain its difficulty level. For multiple UAVs, the K-means clustering algorithm has been improved based on difficulty levels to achieve balanced task allocation. Simulation experiments demonstrated that the difficulty level could effectively reflect the difficulty of tasks and that the proposed algorithms could enable UAVs to achieve balanced task allocation.

Abstract
SARS-CoV-2 transmission dynamics within households involving children are complex. We examined the association between paediatric index case (PIC) age and subsequent household SARS-CoV-2 transmission among cases reported to the Minnesota Department of Health between March 2021 and February 2022. In our primary analysis, we used logistic regression to estimate odds ratios adjusted for race/ethnicity, sex, geographic region, and disease severity among households with an unvaccinated PIC. We performed a secondary analysis among households where the PIC was eligible for vaccination adjusting for the same covariates plus time since the last vaccination. Both analyses were stratified by variant wave. During the Alpha wave, PICs of all age groups had similar odds of subsequent transmission. During Delta and Omicron waves, PICs aged 16–17 had higher odds of subsequent transmission than PICs aged 0–4 (Delta OR, 1.32; [95% CI, 1.16–1.51], Omicron OR, 4.21; [95% CI, 3.25–5.45]). In the secondary analysis, unvaccinated PICs had higher odds of subsequent transmission than vaccinated PICs (Delta OR 2.89 [95% CI, 2.18–3.84], Omicron OR 1.35 [95% CI, 1.21–1.50]). Enhanced preventative measures, especially for 12–17-year-olds, may limit SARS-CoV-2 transmission within households involving children.
Global well-posedness and uniform boundedness of 2D urban crime models with nonlinear advection enhancement
Authors: Jiang Wenjing , Wang Qi 
Published: November 2024

Abstract
We study the global well-posedness and uniform boundedness of a two-dimensional reaction–advection–diffusion system with nonlinear advection. This strongly coupled system of nonlinear partial differential equations represents the continuum of a 2D lattice model designed to describe residential burglary, where each location is characterised by a tractability value that varies in both space and time. We show that the model with sublinear advection enhancement is globally well-posed, with a unique solution that is classical and uniformly bounded in time. Our results provide valuable insights into the development of urban crime models with nonlinear advection enhancements, making them suitable for broader applications, including nonlocal or heterogeneous near-repeat victimisation effects.

Summary
In the Anthropocene, recognising nature’s role in human well-being is pivotal for biodiversity conservation. Despite their significance, knowledge gaps persist regarding ecosystem services, even for well-studied species like vultures. Our study focuses on the Griffon Vulture Gyps fulvus in Sardinia, Italy, exploring their cultural and regulating services, including carcass disposal and resulting greenhouse gas (GHG) mitigation. Through surveys of natural reserve visitors and data on carcass provision and GHG emissions, we assess public perception, economic value, and environmental impacts associated with vultures. The public perception of Griffon Vultures is predominantly positive, with a strong acknowledgment of their role in disease prevention and carcass disposal, highlighting their contribution to regulation services. Furthermore, vultures are widely recognised as a key element characterising the agropastoral landscapes of Sardinia, underscoring their cultural importance. The economic evaluation, through willingness to pay for vulture-watching and photography opportunities, indicates a significant appreciation of these birds, with almost three-quarters of respondents willing to pay an entrance fee at vulture observation sites. We also show that supplanting the disposal role of vultures at studied feeding sites (during 2017–2022) would result in the emission of 96 tons of CO2 equivalent, which highlights the critical role of vultures in climate mitigation. This study not only sheds light on the ecological and cultural significance of Griffon Vultures in Sardinia but also underscores the economic and environmental benefits of their conservation. It emphasises the need for continued efforts in vulture conservation, integrating ecological, cultural, and economic perspectives to foster a sustainable coexistence between humans and wildlife.
