An Analysis of Tropical Transport: Influence of the Quasi-biennial Oscillation [PDF]

, 1997
An analysis of over 4 years of Upper Atmosphere Research Satellite (UARS) measurements of CH4, HF, O3, and zonal wind are used to study the influence of the quasi-biennial oscillation (QBO) on constituent transport in the tropics.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...

Deep Caries Management: EFCD‐ESE‐ORCA S3‐Level Clinical Practice Guideline

International Endodontic Journal, EarlyView.
ABSTRACT Objective To develop an evidence‐based S3‐level clinical practice guideline for the management of deep and extremely deep caries in vital permanent teeth. Methods An evidence‐based medical guideline based on systematically searched and appraised evidence as well as a structured consensus (S3‐level) was jointly developed by the European ...

DIRECTION FINDING OF HF SIGNALS SCATTERED BY IONOSPHERIC IRREGULARITIES USING SMALL SIZE ANTENNA

Radio Physics and Radio Astronomy, 2016
Purpose: A modification of the Doppler Interferometry Technique is suggested to enable estimating angles of arrival of comparatively broadband HF signals scattered by random irregularities of the ionospheric plasma with the use of small-size near ...

A Numerical Study of the Effects of Density Contrast on Flow, Turbulence, and Mixing at the Negro/Solimoes Confluence, Brazil

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

The Role of Inspiratory Muscle Strength in Functional Capacity and Left Atrial Strain in Patients With Heart Failure With Mildly Reduced and Preserved Ejection Fraction

Clinical Cardiology, Volume 49, Issue 4, April 2026.
In patients with HFpEF and HFmrEF, maximal inspiratory pressure is independently associated with exercise capacity, including peak oxygen uptake and 6‐minute walk distance, as well as left atrial reservoir strain. These findings highlight inspiratory muscle strength as a relevant functional determinant of exercise intolerance, independent of age and ...

Revolutionizing Heart Failure Management With Artificial Intelligence: A Narrative Review of Diagnostic, Prognostic, and Therapeutic Innovations

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aims Heart failure (HF) remains a major global health burden, affecting over 64 million individuals worldwide. Early detection and optimal management are often limited by subjective interpretation of diagnostic tests and variable clinical expertise. Artificial intelligence (AI) has emerged as a transformative technology that can
