Advanced Multipurpose Spectroscopic Nanobio‐Device for Concurrent Lab‐on‐a‐Chip Label‐Free Separation and Detection of Extracellular Vesicles as Key‐Biomarkers for Point‐of‐Care Cardiovascular Disease Diagnostics

open access: yesAdvanced Healthcare Materials, EarlyView.
AIMSPec‐LoC is a novel lab‐on‐a‐chip platform integrating size‐based extracellular vesicle (EVs) separation with label‐free Raman spectroscopy and AI‐powered classification via SKiNET. This high‐throughput, portable system enables real‐time, multiplexed molecular fingerprinting of EVs from biofluids, offering transformative potential for early, non ...

Seeing inside the Body Using Wearable Sensing and Imaging Technologies

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores wearable technologies for noninvasive internal health monitoring. It categorizes approaches into indirect sensing (e.g., bioelectrical and biochemical signals) and direct imaging (e.g., wearable ultrasound and EIT), highlighting multimodal integration and system‐level innovation toward personalized, continuous healthcare.

The underdoped-overdoped transition in YBa_2Cu_3O_x

open access: yes, 2000
Oxygen doping in metallic YBa_2Cu_3O_x induces quadrupolar "alpha-ortho'', and breathing "beta-ortho" deformations of the CuO_2 planes. Breathing beta-ortho deformations favour hybridizations of the pd sigma Cu3d_x^2-y^2 - O2p_x,y with the pd pi Cu3d_x,z,

Dysfunctional breathing: a review of the literature and proposal for classification

open access: yesEuropean Respiratory Review, 2016
Dysfunctional breathing is a term describing breathing disorders where chronic changes in breathing pattern result in dyspnoea and other symptoms in the absence or in excess of the magnitude of physiological respiratory or cardiac disease.

Advancing from MOFs and COFs to Functional Macroscopic Porous Constructs

open access: yesAdvanced Materials, EarlyView.
This review study investigates the recent progress and methodologies for manufacturing metal–organic framework (MOF) or covalent–organic framework (COF)‐based 3D structured macroscopic porous constructs with high structural integrity, providing the possibility to control their porosity across dimensions.

Vibrational Aspects of the SU(2) Skyrmion

open access: yes, 1993
We treat the Skyrme model with the breathing mode in a situation involving two quartic terms. It is seen that there is a new limit for large $e$ due to the breathing mode not found in the usual rotating hedgehog.Comment: 15 pages, ADP-93-206 ...
