A Linear‐to‐Linear Cross‐Polarization Conversion q‐BIC Metasurface for Transmission Mode Mid‐Infrared Spectral Filtering

open access: yesLaser &Photonics Reviews, EarlyView.
Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...

Enhanced Dielectric Properties of In + Ta Co-Doped TiO2 Ceramics Synthesized via a Green Egg White Route: Low-Temperature Sintering and Microstructural Insights

open access: yesSci
Giant dielectric oxides are attractive for next-generation capacitors and related applications, but their practical use is limited by high loss tangent (tanδ), strong temperature dependence of dielectric permittivity (ε′), and the need for energy ...

Contribution of the Ade Resistance-Nodulation-Cell Division-Type Efflux Pumps to Fitness and Pathogenesis of Acinetobacter baumannii

open access: yesmBio, 2016
Overexpression of chromosomal resistance-nodulation-cell division (RND)-type efflux systems with broad substrate specificity contributes to multidrug resistance (MDR) in Acinetobacter baumannii.

Low Frequency of Dementia with Lewy Bodies Diagnosis in a Colombian Memory Clinic

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background The global burden of dementia is increasing, particularly in low‐ and middle‐income countries. Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia but remains underreported and frequently misdiagnosed. Its prevalence in Latin America is largely unknown.

Dynamics of Nerve Conduction Studies in Patients With Guillain–Barré Syndrome

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims The value of electrodiagnostic subtyping of Guillain–Barré syndrome (GBS) is still debated. This study aimed to determine the diagnostic yield, timing, and changes of the electrodiagnostic subtyping in patients with GBS in serial nerve conduction studies (NCS).

CUPID pre-CDR

open access: yes, 2019
CUPID is a proposed future tonne-scale bolometric neutrinoless double beta decay ($0 $) experiment to probe the Majorana nature of neutrinos and discover Lepton Number Violation in the so-called inverted hierarchy region of the neutrino mass. CUPID will be built on experience, expertise and lessons learned in CUORE, and will exploit the current ...

Was malthus right? a var analysis of economic and demographic interactions in pre-industrial England [PDF]

open access: yes, 2006
This paper shows that the interaction between economic and demographic variables in England before the onset of modern economic growth did not fit some crucial assumptions of the Malthusian model. I estimated a vector autoregression for data on fertility,

Lions as Bone Accumulators? Exploring Multi‐Predator Contributions to the Olduvai Carnivore Site (OCS) (Tanzania) Through AI and Metric Analyses

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...

Short IQCODE as a screening tool for MCI and dementia: preliminary results

open access: yesDementia & Neuropsychologia
Reaching a diagnosis may be difficult in the initial stages of dementia, especially in low educated individuals, when informant reports may be useful. Objectives: To compare the sensitivity and specificity of the IQCODE against cognitive tests applied in

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...
