Abstract Understanding island biodiversity requires studying the processes driving its assembly and examining how these processes vary over time, across lineages, and across different islands. The DAISIE (Dynamic Assembly of Island biota through Speciation, Immigration, and Extin...

The extreme diversity of retinal amacrine cells has deep evolutionary roots
Amacrine cells (ACs) comprise a heterogeneous class of inhibitory neurons in the vertebrate retina, exhibiting morphological and functional complexity rivaling that of cortical interneurons. Here, we integrate single-cell and single-nucleus transcriptomic atlases from 24 vertebra...

Background Wheezing, a symptom reflecting bronchial obstruction, is frequently reported in preterm-born infants. No objective and reliable tool is available to assert this diagnosis with minimal patient cooperation. Nocturnal tidal breathing measurements by impedance pneumography...

Contrasting seasonal roles of external forcing and internal variability in East Asian temperature
How to reliably separate external forcing (EXF) and internal variability (IV) components of regional temperature variation is of critical importance in East Asia. We implement here an EOF-based semi-empirical framework to avoid spurious teleconnections often present with conventi...

Accelerating charging dynamics of electric double-layer capacitors
Electric double-layer capacitors (EDLCs), consisting of an ionic fluid between two metallic electrodes, are electrochemical energy storage devices complementary to batteries, allowing for a faster charge/discharge. The charging dynamics in response to a voltage step features a va...

Abstract The induction part of intermolecular interaction energy describes the effect of the mutual polarization of subsystems. Low-order induction effects can be reasonably described by symmetry-adapted perturbation theory (SAPT), but the capture of important higher-order polari...

Thermohaline gradients and frontal regimes in the northwestern Tropical Atlantic
Abstract. At the edge of the Amazon River plume, stirring by the North Brazil Current (NBC) and its eddies creates sharp surface thermohaline gradients on scales of O(1–100) km. This study provides a comprehensive picture of these gradients and fronts associated with the region's...

Abstract Propagating waves on the ocean surface can be represented as a stochastic process whose statistics are characterized by a spectrum. This paper reviews methods for measuring the wave spectrum and related quantities. Observations begin by sensing fluid dynamical properties...

Abstract Introduction Recent proteomic studies have identified both established and novel proteins in genetic frontotemporal lobar degeneration (FTLD). However, it remains unclear at what point in the disease these proteins deviate from normal levels and how their trajectories re...

Abstract Hematopoietic cell transplantation, cellular and gene therapies, and (CAR)-T cells have revolutionized outcomes in hematologic disorders. However, major disparities persist in their availability, accessibility, and affordability, particularly in low- and middle-income co...

<ns5:p> We present a genome assembly from a specimen of <ns5:italic>Rhynchopelta concentrica</ns5:italic> (peltospirid gastropod; Mollusca; Gastropoda; Neomphalida; Peltospiridae). The genome sequence has a total length of 716.07 megabases. Most of the assembly (92.08%) is scaffo...

Termites play a crucial role in forming major tropical soils: insights from a deep Ferralsol
Abstract Soil bioturbation is increasingly recognized as a key driver of pedogenesis in tropical ecosystems, influencing above- and below-ground biodiversity, nutrient cycling, and aggregate stability across different spatial and temporal scales. This ecological process may play...

Background/Objectives: Medication safety is a critical concern in older adults due to age-related vulnerability, multimorbidity, and polypharmacy. Pro Re Nata (PRN, “as needed”) prescribing is common in geriatric care but may be interpreted inconsistently across healthcare profes...

Investigating a Devonian vertebrate assemblage with synchrotron microtomography of coprolites
Abstract Fossilised faeces (coprolites) are a unique source of information as they record palaeontological evidence of animal behaviour (autecology) as well as interactions between extinct organisms and their environment (synecology). Four samples bearing coprolites found in a ne...

Nuclear activities and interactome of the NS5 protein of tick-borne encephalitis virus
Orthoflaviviruses are RNA viruses responsible for significant diseases in humans, domesticated animals, and wildlife. Their NS5 protein is central in viral replication, functioning both as an RNA-dependent RNA polymerase and a methyltransferase, while also modulating cellular pro...

Abstract Frailty, defined by multisystem physiological decline and heightened vulnerability to stressors, is typically associated with aging and chronic disease. However, its relevance in apparently healthy individuals remains poorly understood. Identifying frailty in this popula...

Background: Mastoid and epitympanic obliteration has become a widely used technique in cholesteatoma surgery to reduce postoperative recurrence. However, recurrent disease still occurs in some patients, and the anatomical sites and mechanisms of recurrence after obliteration rema...

Recurrent pregnancy loss (RPL) is a multifactorial condition, with over 50% of cases remaining unexplained. The absence of therapeutic consensus raises questions regarding referral for assisted reproductive technology (ART). To evaluate live birth rates and predictors of success...

Validation and Spin of the Bright Part of Gaia DR2 and DR3
ABSTRACT The Gaia Data Release 3 (DR3) is an important step in the realization of the future Gaia reference frame. Ideally, across G magnitudes from 3 to 21, the Gaia DR2 and DR3 objects with their positions (, ) and proper motions (, ) should be expressed in a nonrotating refere...

Marine microalgae obtain essential sulfur through energetically costly, assimilatory reduction of sea-salt sulfate, so the ability for osmotrophic incorporation of reduced sulfur would confer them adaptability in energy-limiting conditions. Dimethylsulfoniopropionate (DMSP) is a...
