Collective phases in overdamped magnetic self-propelled spherocylinders

We study the collective dynamics of self-propelled spherocylinders carrying magnetic dipole moments in two dimensions. Magnetic interactions are modeled as two opposite monopoles ± Q separated by a distance ℓ along the particle orientation axis, an idealized dumbbell model that r...

Trophic position structures physiological trade-offs between metabolic and detoxification pathways in sympatric passerines

Abstract Resource use links ecological context to organismal performance, yet whether dietary breadth or trophic position is more closely associated with physiological state in wild birds remains unclear. We used a natural trophic gradient in a sympatric passerine assemblage to t...

Cognitive vergence and pupil response during oddball task are associated with Alzheimer´s disease cerebrospinal fluid neurodegenerative biomarkers

Alzheimer’s disease (AD) can be diagnosed using cerebrospinal fluid (CSF) biomarkers reflecting amyloid and tau pathology. However, they provide no information about functional network status. We aimed to determine whether CSF biomarkers (Aβ42, p-Tau, t-Tau, and Aβ42/p-Tau ratio)...

Coastal streetlights shape intertidal sessile community abundance and are associated with altered post-disturbance recovery in urban rocky shores

Coastal urban environments concentrate high levels of artificial light at night (ALAN), yet how persistent light pollution interacts with urban habitat conditions to shape intertidal community structure remains poorly understood. Here, we combined field surveys on natural rocky p...

Removing the fine print: Disclosure, standardized products, and consumer outcomes

Hidden fees can distort consumer decision-making. In response, regulators historically have (a) improved disclosure to make fees more salient or (b) standardized products to restrict what fees can be charged. We use Chilean administrative data and a multi-stage natural experiment...

Cognitive vergence and pupillary responses as functional oculomotor signatures to differentiate AT(N) biological profiles in older adults with mild cognitive impairment

Abstract The locus coeruleus (LC), the earliest site of tau accumulation in Alzheimer’s disease, directly influences pupillary and vergence oculomotor systems. Whether task-evoked oculomotor dynamics can non-invasively differentiate AT(N) profiles, A+T+ (biological Alzheimer’s di...

A framework to compare the performance of spatial disaggregation methods of statistical climate downscaling in South America

Study region Chile and South America. Study focus Climate change is simulated at a coarse scale with General Circulation Models. Impact and regional studies require downscaling to increase spatial resolution. Several downscaling methods exist, but most studies do not analyze or c...

Optimal Public Sector Premium, Talent Misallocation, and Aggregate Productivity: Evidence From Egypt

ABSTRACT We develop a tractable general equilibrium model to quantify the long‐run aggregate productivity gains from adjusting the public‐sector premium and the size of the public sector to their productivity‐maximizing levels. The model incorporates an endogenous choice between...

Robustness of Regionally Derived, Short-Duration Rainfall Depth-Duration-Frequency Estimates to the Choice of Minimum Interevent Time: Evidence across Climates, Rain Gauge Densities, and Regionalization Approaches

Abstract The choice of minimum interevent time (MIT)—a criterion used to discern independent events from a continuous rainfall record—can affect the resulting partial duration series (PDS) and depth-duration-frequency values (DDFs). However, the mechanisms by which MIT choice aff...

Local supplier rescue and relayable liquidity

This article develops a model of sequential supplier rescue in rooted supply trees. An active customer can meet a direct supplier’s fixed activation requirement, but relationship-specific support cannot finance more remote suppliers. Activation instead releases the supplier’s own...

Latin American Studies and Irish Studies: reflections on the representation of Latin America in the writing of James Joyce

Why should those of us working in Irish Studies care about the research, conclusions, and insights emerging from the field of Latin American Studies? Through a reading of James Joyce’s Finnegans Wake in dialogue with previous scholarship on Dubliners and Ulysses, this article arg...
