Piezo1‐mediated unfolded protein response in goblet cells regulates intestinal mucus barrier homeostasis through the Ca2+–IRE1α–XBP1 pathway

Clinical and Translational Medicine, Volume 16, Issue 11, November 2026.
This study demonstrates that activation of Piezo1 channels in goblet cells by intestinal mechanical stimulation modulates ER calcium homeostasis via calcium ion (Ca2+) flux, which in turn regulates Mucin2 production and synthesis through the IRE1α‐XBP1. Intraperitoneal administration of Yoda1 alleviates mucus barrier impairment in DSS/WAS‐treated mice.

A New Approach in Designing Multi-Layer Frequency Selective Surfaces based on Tuning Pole-Zeros of Individual Layers [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2015
In this paper, a new approach (not new technique) is introduced for designing frequency selective surfaces (FSSs). We try to compose the desired frequency response using the frequency response of each constituent FSS.

Advances in High‐Temperature Microwave‐Absorbing Materials With Rare Metals: Preparations, Classifications, and Strategies

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT High‐temperature microwave‐absorbing materials (HTMAMs) are vital for the electromagnetic stealth of hypersonic aircraft and aerospace engines. Traditional carbon‐based or magnetic‐based absorbers suffer from oxidation, Curie‐temperature limitations, and impedance mismatch under extreme conditions.

Perovskite‐Based Catalysts for the Oxygen Evolution Reaction: Synthesis, Device Relevant Performance, and Scale‐Up Strategies

Small, Volume 22, Issue 61, 2 November 2026.
Perovskites are emerging as catalysts for acidic oxygen evolution in proton exchange membrane water electrolyzers. This manuscript focuses on catalyst behavior under device‐relevant conditions, highlighting surface reconstruction, elemental utilization, and membrane electrode assembly performance. By linking materials design with electrolyzer operation,

New Constraints on the Lunar Crust and Upper Mantle From Multiple Geophysical Data Sets

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Determining the crust–mantle boundary of the Moon has been an important topic in lunar interior studies. However, strong seismic scattering in the lunar subsurface has made it challenging to identify clear crustal reflections or converted seismic phases.

Tunable antenna radome based on graphene frequency selective surface

AIP Advances, 2017
In this paper, a graphene-based frequency selective surface (FSS) is proposed. The proposed FSS exhibits a tunable bandpass filtering characteristic due to the alterable conductivity of the graphene strips which is controlled by chemical potential. Based
