Restoring joint homeostasis: A dynamically adaptive meniscal scaffold prevents osteoarthritis by replicating native biomechanics

open access: yesBMEMat, EarlyView.
This work establishes a paradigm shift from static structural mimicry to dynamic functional replication. By restoring the native “compression‐to‐tension” mechanism, the scaffold ensures robust mechanical stability and superior chondroprotection.

New type of horn based on variable metasurface

open access: yes, 2011
This paper demonstrates the design and the analysis of a novel type of horn antennas with a potentially higher directivity. The idea is to replace one plate of an H-plane horn antenna with a plate that has specially designed surface impedance.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Monoclonal Antibodies; Detection Tools for Wheat Alpha‐Amylase Proteins

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Expression of alpha‐amylase proteins during germination or other physiological events may lower grain soundness and have a negative impact on end‐use quality. The objective of the current study was to validate two new monoclonal peptide antibodies for wheat alpha‐amylases and describe alpha‐amylase expression in ...

A configuration to double the gain of pyramidal horn antenna using single layer frequency selective surface

open access: yesIET Microwaves, Antennas & Propagation
A gain enhancement technique in pyramidal horn antenna using a slot type band pass frequency selective surface (FSS) is presented. The horn antenna without FSS has achieved a measured gain of 10.5 dBi at 10 GHz, while the antenna with the single layer ...

Equivalent Circuit of a Quadraxial Feed for Ultra-Wide Bandwidth Quadruple-Ridged Flared Horn Antennas [Elektronisk resurs]

open access: yes, 2015
An equivalent circuit model of a quadraxial feed for ultra-wide bandwidth quadruple-ridged flared horn (QRFH) antennas is presented. The circuit is synthesised by only 3 unknowns and achieves an accurate input impedance for a wide range of dimensions ...

The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO

open access: yesCarbon Energy, EarlyView.
In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...

An integrated finite element-mode matching-plane wave expansion code for horn antenna analysis

open access: yes, 2001
A fully automatic code for analysing horn antennas is here presented. The code exploits Finite Elements where geometry complexity requires it, while Mode Matching is used where applicable.
