Anhangueridae is the most common pterosaur group in the Araripe Basin, particularly in the Romualdo Formation. Here we describe a previously unreported specimen from the Museu de Ciências da Terra (Rio de Janeiro, Brazil), MCT.R.1491, consisting of a partial lower jaw associated...

The genus Cereus (Cactaceae), widely distributed across arid and semi-arid environments of South America, exhibits adaptive capacity that is partly associated with proteins involved in lipid metabolism and stress responses, such as non-specific lipid transfer proteins (nsLTPs). A...

Abstract Esterases are a class of enzymes that catalyze the hydrolysis of carboxylic ester bonds and are widely utilized in the food, pharmaceutical, and detergent industries. In this study, we report the identification and comprehensive characterization of a novel esterase (TbEs...

New Laws, Old Habits: Intelligence Reform Failure in Brazil
Third-wave democracies have adopted the standard toolkit of intelligence reform—new legal frameworks, meritocratic recruitment, and parliamentary oversight—yet domestic surveillance and political instrumentalization persist. We advance an underexplored variable to explain this ga...

A Review of Molecular Representations in Quantum Machine Learning
This review synthesizes state-of-the-art quantum machine learning (QML) techniques for molecular modeling, focusing on strategies designed to overcome the limitations of Noisy Intermediate-Scale Quantum (NISQ) hardware. A central challenge is the encoding of high-dimensional chem...

Electrical excitation selects electrothermal hysteretic operating regimes in VO$$_2$$ devices
Abstract Vanadium dioxide (VO $$_2$$ ) exhibits a sharp metal–insulator transition accompanied by intrinsic thermal hysteresis, enabling rich nonlinear electro–thermal dynamics and a broad range of device functionalities. In VO $$_2$$ devices, electrical hysteresis is commonly in...

Cognitive Functional Therapy for Plantar Heel Pain: A Case Series
BACKGROUND: Plantar heel pain is a prevalent musculoskeletal condition frequently associated with persistent pain, disability, and biopsychosocial contributors. Although guideline-based care has evolved, management often remains centered on passive and tissue-focused strategies,...

Abstract Cardiac arrhythmias are associated with structural and electrical remodeling processes that generate heterogeneous arrhythmogenic substrates characterized by low-voltage areas and abnormal conduction. Although electroanatomical voltage mapping is widely used for substrat...

Unintentional islanding is defined as the condition in which a section of the power grid continues to be energized by distributed generators after disconnection from the utility grid, for example, due to a fault. This situation remains a significant protection challenge in microg...

Stable Black Strings from Warped Backgrounds
A bstract We show that spacetime curvature alone can classically stabilize black strings. Working within a consistent five-dimensional dilaton-gravity system with a flat brane, we find that sufficiently large black strings are classically stable when they extend from the brane to...

Background: Angiostrongylus cantonensis is a neurotropic nematode recognized as the leading cause of eosinophilic meningitis worldwide. Despite its growing medical importance, therapeutic options for angiostrongyliasis remain limited, highlighting the need for new anthelmintic ag...

Abstract Phenothiazines are widely studied as closed-shell photosensitizers; however, their open-shell oxidized forms remain largely unexplored in photochemical contexts. Here, we investigate the photophysics and reactivity of the radical cation of 10H-phenothiazine (PHT•+) using...

Learning aligned EEG representations with subject-specific encoders
Cross-subject EEG decoding promises more training data, but it also exposes neural networks to strong inter-subject distribution shifts. We study whether task supervision and architecture alone can learn subject-aligned representations. We replace a shared EEG encoder with subjec...

A mechanistic approach about oxidative, mutagenic, and cytotoxic effects of an organotellurane
Abstract Organotellurium (OTe) compounds have pharmacological properties, including leishmanicidal, antimalarial, and antifungal activities. Herein, we assessed cytotoxicity effects of OTe RF07 in a panel of tumor cell lines, as well as its oxidative, toxicity, and hemolytic acti...

Ten years after: a review of squidpop assays to test predation in aquatic habitats
Ten years have passed since the introduction of a standardized methodology for measuring consumption rates by animals in aquatic environments, known as “squidpops”. Its low-cost, easy-to-implement design made it an alternative for studies aiming to compare consumption rates acros...

ABSTRACT Three forested dispersal corridors have been proposed within the diagonal of open/dry landscapes in South America and the relative importance of each one has been the subject of debate for forest organisms. We analysed the biogeographical history of three snake genera (...

Insects display adaptive diversity in their secretory systems, which mediate ecological interactions ranging from defence to adhesion. Within Diptera, the co-occurrence of silk and venom represents a rare functional combination. Here, we integrate multi-species transcriptomics, c...

PhotocatalyticHydrogen Production from CellobioseUsing TiO2@Pt(0.5) Immobilized Photocatalyst
Abstract Photocatalytic reforming of biomass-derived carbohydrates is a potentially promising route for sustainable hydrogen production under mild conditions. In this work, we investigated the photocatalytic reforming of cellobiose using TiO2@Pt(0.5) immobilized on a glass plate...
