Healthcare occupancy data as an early warning indicator of infectious disease surges in São Paulo

Early detection of infectious disease surges is critical for effective public health response, yet traditional surveillance systems often suffer from delayed reporting. Here, we investigate whether passively collected occupancy data from healthcare facilities can act as an early...

Why do high-temperature gas mixtures exhibit nearly ideal behavior even at high pressures? A statistical-mechanical perspective on the Haber–Bosch process

Abstract The ideal gas approximation is usually associated with low-pressure conditions, while high pressures are generally expected to lead to significant deviations from ideality. However, the behavior of many chemically relevant systems remains nearly ideal even at high pressu...

Construction and characterisation of the DarkSide-20k veto silicon photo-multiplier tiles

Abstract Silicon photo-multipliers (SiPMs) are state-of-the-art sensors capable of detecting a single photoelectron under cryogenic conditions, with potentially lower radioactivity than widely used photomultiplier tubes. The DarkSide-20k experiment, designed to perform direct dar...

Time-varying formation control via output feedback for multi-agent systems over switching networks with hidden Markov dynamics

This paper addresses time-varying formation control for a class of multi-agent systems. In particular, distributed static output control laws are designed for homogeneous discrete-time linear multi-agent systems whose network topologies switch according to an unknown Markov chain...

Tail-Dependent Price Escalation Risk in Road Projects: A Hybrid LSTM-Gumbel Copula Model for Probabilistic Contingency Estimation

Abstract Road and bridge projects are exposed to escalation in key construction inputs such as diesel, cement, structural steel, and construction steel, where common shocks can generate jointly adverse price movements and weaken fixed-percentage contingency practices. Prior const...

A comprehensive survey of cryptic molluscs associated with autonomous reef monitoring structures (ARMS) in Trindade Island (South Atlantic)

Cryptic biodiversity in marine ecosystems remains largely underestimated due to the inherent difficulty of sampling organisms inhabiting reef microhabitats without causing significant environmental disturbance. This knowledge gap is particularly evident on highly isolated Brazili...

Adherence, motivational factors, and injury rates in runners using minimalist vs. conventional shoes: A cross-sectional study of 4719 Brazilian runners

Background In the early 2010s, a movement advocating a more natural running style, such as running in minimalist shoes, emerged. However, little is known about runners' adherence to these shoes, interest in them, and injury rates associated with them. Objective To investigate adh...

HLA-DRB1 Polymorphisms Modulate the Dynamic Compatibility between the Presentation of EBNA1400–413 and MBP85–99

Abstract Multiple sclerosis (MS) shows a strong genetic association with HLA-DRB1 alleles and a consistent epidemiological association with Epstein–Barr virus (EBV) infection. However, it remains unclear how HLA-DRB1 polymorphisms modulate the presentation of autoantigens and vir...

(±)-Nigronetides A−D and Nigronetides E−H, Complex Polyketides Produced by the Marine-Derived Fungus Nigrograna sp. M13

Abstract (±)-Nigronetides A−D (1−4) and nigronetides E−H (5−8), polyketides with complex carbon skeletons, were isolated from cultures of the marine-derived fungus Nigrograna sp. M13, presenting three novel carbon skeletons. While the planar structures and relative configuration...

Definitions and functions of moral emotions within developmental psychology: a scoping review

Abstract Background Moral psychology has traditionally emphasized moral reasoning; however, increasing attention has been directed toward moral emotions and their role in children’s moral development. This shift has been accompanied by conceptual ambiguity regarding how moral emo...

Stacked enviromic–genomic models improve prediction of genotype performance in new environments

Abstract Genotype-by-environment interaction is a major challenge for breeding programs, limiting the predictive ability of genomic selection in untested environments. We propose a Stacked Generalization framework that integrates linear mixed models (factor analytic and genomic b...

Geochemical fingerprints and tectonic setting of the Late Palaeozoic marginal basin of the Bariloche Complex (SW Gondwana), North Patagonian Andes of Argentina

The understanding of the Late Palaeozoic evolution of the south-western Gondwana margin is limited due to a lack of outcrops and data. New insights were achieved by fieldwork, petrographic characterization and geochemical fingerprinting on metasedimentary and interlayered metabas...

Six Minute Walk Test and Clinical Outcomes in Pediatric Heart Transplant Candidates

Abstract Heart transplantation is the main therapeutic option for children and adolescents with cardiomyopathies (CM) and congenital heart disease (CHD) who progress to advanced heart failure. However, longitudinal data on functional capacity in pediatric transplant candidates re...

Descriptive Histological and Histomorphometrical Comparison of Four Xenogeneic and Synthetic Bone Blocks for Mandibular Onlay Augmentation in Rabbits

Background: This exploratory study provided a primarily descriptive comparison of two xenogeneic and two synthetic blocks for mandibular onlay augmentation in rabbits. Methods: Twelve rabbits received bilateral block grafts, providing 24 sites allocated to Bio-Oss® Block, SP-Bloc...

Enforced aqueous carbonation of heterogeneous cementitious waste fines: CO 2 uptake and performance as supplementary cementitious materials in Portland cement

Enforced carbonation of cementitious wastes is a strategy to mitigate CO2 emissions and generate reactive supplementary cementitious materials (SCMs), yet few studies have analyzed real sources. In this study, three heterogeneous wastes were investigated: hardened cement paste (H...

The above- and below-ground root-to-shoot ratio in urban trees – a ground penetrating radar assessment

Abstract Urban trees are renowned for providing fundamental ecosystem services that stem from their proper development in cities. However, the urban environment poses significant challenges for trees, including impairments from the above- and below-ground grey infrastructure. Imp...

Implications of self-medication among socially vulnerable older adults in the COVID-19 era (2021–2023)

Self-medication is a public health issue, exacerbated by limited healthcare access and the search for quick relief. In Brazil, resource shortages and the COVID-19 pandemic have intensified this behavior, leading to the indiscriminate use of medications among older adults in socia...

Nesting in human-made versus natural cavities affects colony demography and nest architecture in an urban-adapted Neotropical stingless bee

Abstract Habitat loss and urbanisation create challenging environments for many bee species, but some show a remarkable ability to adapt to urban environments, e.g. by nesting in buildings and foraging in gardens or parks. Little is currently known about the consequences of livin...

How common is alcohol use disorder in posttraumatic stress disorder? A systematic review, meta‐analysis, and moderator analysis

BACKGROUND AND OBJECTIVES: Comorbidity between posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) complicates care, yet reported prevalence varies widely across settings and methods. We estimated AUD prevalence among adults with PTSD and identified sources of var...

Multifunctional NaNbO3: Photocatalytic Degradation of Methylene Blue and Intrinsic Antimicrobial Activity against Enterococcus faecalis and Candida albicans

Abstract In this paper, sodium niobate (NaNbO3) was synthesized by the microwave-assisted hydrothermal method at 150 °C for 70 min, followed by calcination at 550 °C for 2 h. X-ray diffraction revealed the coexistence of orthorhombic P21ma and Pbma phases, while scanning electron...
