Differentially Fed, Wideband Dual-Polarized Filtering Dielectric Resonator Patch Antenna Using a Sequentially Rotated Shorting Coupling Structure

Photonics
A wideband dual-polarized dielectric resonator antenna (DRA) with gain-filtering response was proposed in this paper. First, a differentially fed, low-profile crossed-DRA was used to obtain orthogonal polarizations with two resonant modes.

Mannan oligosaccharide requires functional ETC and TLR for biological radiation protection to normal cells

BMC Cell Biology, 2018
Background Low LET Ionizing radiation is known to alter intracellular redox balance by inducing free radical generation, which may cause oxidative modification of various cellular biomolecules. The extent of biomolecule-modifications/ damages and changes

Null placing in radiation patterns by shaping antenna edges

Electronics Letters, 1972
A simple null-placing technique is given by the shaping of antenna edges in the form of a step at the critical point of radiation. The E plane pattern of a pyramidal horn is used as an example, for which theoretical and measured results are given.

Sub‐Diffraction Nanolithography of Halide Perovskite via Reversible All‐Optical Crystallization–Decomposition

Advanced Materials, EarlyView.
A reversible, all‐optical modulation strategy enables resist‐free, sub‐diffraction nanolithography of halide perovskite films. Leveraging 800 nm fs laser‐induced crystallization and 365 nm laser driven decomposition, reconfigurable patterning achieves feature sizes down to 93.5 nm. This chemistry‐free approach offers dynamic control over optoelectronic

GlyCAM1 negatively regulates monocyte entry into the optic nerve head and contributes to radiation-based protection in glaucoma

Journal of Neuroinflammation, 2017
Background We previously reported a profound long-term neuroprotection subsequent to a single radiation-therapy in the DBA/2J mouse model of glaucoma.

RB expression confers sensitivity to CDK4/6 inhibitor–mediated radiosensitization across breast cancer subtypes

JCI Insight, 2022
Standard radiation therapy (RT) does not reliably provide locoregional control for women with multinode-positive breast cancer and triple-negative breast cancer (TNBC).

Revisiting Vaidya Horizons

Galaxies, 2014
In this study, we located and compared different types of horizons in the spherically symmetric Vaidya solution. The horizons we found were trapping horizons, which can be null, timelike, or spacelike, null surfaces with constant area change and also ...
