Abstract Magnetic singularities known as Bloch points (BPs) present a fundamental challenge for micromagnetic theory, which is based on the assumption of a fixed magnetization vector length. Due to the divergence of the ...

Graphene layers are known to stack in two stable configurations, namely, ABA or ABC stacking, with drastically distinct electronic properties. Unlike the ABA stacking, little has been done to experimentally investigate t...

The central theme of cavity quantum electrodynamics is the coupling of a single optical mode with a single matter excitation, leading to a doublet of cavity polaritons which govern the optical properties of the coupled s...

A systematic analysis of defect textures in faceted nanoparticles with polygonal configurations embedded in a nematic matrix is performed using the Landau de Gennes model, homeotropic strong anchoring in a square domain...

Cave 338 is a high-altitude prehistoric site located at 2,235 m a. s.l. in the eastern Pyrenees (Queralbs, Girona, NE Iberian Peninsula). Excavated between 2021 and 2023, the site preserves an exceptional and well-strati...

Abstract The European Commission requested the EFSA Panel on Plant Health (PLH) to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, ...

This widely distributed, demersal species is associated with rocky bottoms and kelp forests. It is discarded as bycatch in trawl fisheries, but this is not expected to be driving population declines approaching a Near Th...

Chagas disease caused by the protozoan parasite Trypanosoma cruzi is endemic in 21 Latin American countries and the southern United States and now is spreading into several other countries due to migration. Despite the e...

Objective Children and young people (CYP) presenting in mental health crisis to acute paediatric settings represent a growing clinical and system-level challenge. These environments, primarily designed for physical healt...

Abstract A total of 277 rufous-collared sparrows, Zonotrichia capensis Müller, 1776 (Emberizidae), were examined for external parasites. The birds were captured using mist nets in seven locations in northern and central...

Abstract The aim of this study was to assess the association between the distance to the nearest feces, the type of substrate to be studied (feces, soil, grass), and whether a given area was licensed or not with the pres...

Abstract Parasite species are important components of biodiversity, as they provide valuable information about host health, evolutionary relationships, population structures, trophic interactions, the existence of enviro...

The objective of this study is to evaluate the ectoparasites and helminths of the white-crested elaenia, Elaenia albiceps chilensis. Feather mites Anisophyllodes elaeniae, Trouessartia elaeniae, and Analges sp. were dete...

This rocky, intertidal species has a relatively small range, but is common and abundant. There are no known major threats at this time; therefore, it is listed as Least Concern. Fil: Buratti, C.. Instituto Nacional de In...

Abstract Background Although trimodal prehabilitation programs have demonstrated clinical benefits in oncologic surgery, evidence regarding their financial sustainability in public health systems of middle-income countri...

Objective: We aimed to characterise the liver tissue bacterial metataxonomic signature in two independent cohorts of patients with biopsy-proven non-alcoholic fatty liver disease (NAFLD) diagnosis, as differences in the ...

Heavy metal soil contamination is one of the most serious environmental problems, considering both their persistence and progressive accumulation which makes possible the transference to other systems, and could potentia...

Damos a conocer los avances obtenidos en las investigaciones de Arqueología histórica que desarrollamos sobre la batalla de Olivera, Partido de Luján, y el sitio arqueológico existente en el lugar. Este evento enfren...

Chronic hypertension is a major risk factor for preeclampsia (PE), associated with significant maternal and neonatal morbidity. We previously demonstrated that pregnant stroke-prone spontaneously hypertensive rats (SHRSP...

Este artículo informa sobre el desenfardelamiento de un fardo funerario costeño que data de la época Inca. El fardo, el cual fue excavado en el sitio de Rinconada Alta, ubicado en el valle del Rímac, abunda en indume...

It has been recently claimed that cosmologies with time dependent speed of light might solve some of the problems of the standard cosmological scenario, as well as inflationary scenarios. In this letter we show that most...

We fit the BOOMERANG, MAXIMA and COBE/DMR measurements of the cosmic microwave background anisotropy in spatially flat cosmological models where departures from standard recombination of the primeval plasma are parametri...

We consider astronomical and local bounds on the time variation of fundamental constants to test some generic Kaluza-Klein–like models and some particular cases of Beckenstein theory. Bounds on the free parameters of t...

A new method for automatic indexing and retrieval is described. The approach is to take advantage of implicit higher-order structure in the association of terms with documents (“semantic structure”) in order to impro...
