IOP Conference Series: Materials Science and Engineering, 2020 Abstract The radiation pattern is an important parameter of the antenna performance. This parameter needs to be measured not only accurately but also as fast as possible. For this purpose, the automatic measurement system has been developed.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

PLANAR BOWTIE ANTENNA WITH A RECONFIGURABLE RADIATION PATTERN
Progress In Electromagnetics Research C, 2012 This paper presents a novel planar antenna with a reconflgurable radiation pattern. The proposed layout consists of N ‚ 2 monospaced planar bowtie antennas selected one by one by means of a pair of PIN diodes. Experimental results referring to the case of N = 2 and N = 4 are reported and discussed demonstrating the feasibility and efiectiveness of the ...

FEBS Open Bio, EarlyView.TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Effect of terahertz irradiation on DNA damage repair in living cells
FEBS Open Bio, EarlyView.We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Synthesis of flat‐top beampatterns based on simple polynomial transforms of Gaussian excitations
IET Microwaves, Antennas & Propagation, 2023 In the design of antenna arrays which require fast and robust flat‐top beam synthesis, computationally efficient methods are preferred. This feature is usually met by analytical techniques or simple optimisation procedures. On the other hand, in the flat‐
