Macrophage derived VEGF regulates macrophage senescence to inhibit radiation-induced dermatitis [PDF]
Journal of Translational MedicineBackground Macrophages are essential for maintaining tissue homeostasis and accelerating the repair processes; however, their functionality can be severely compromised in pathological conditions such as radiation-induced dermatitis.

Unequally-spaced slot strategy for radiation null reduction in single SIW-embedded antenna element [PDF]
Scientific ReportsThe incorporation of higher-order modes (HOMs) can substantially augment the antenna gain and bandwidth, but this improvement is typically accompanied by compromised radiation performance including radiation nulls and higher side lobe levels.

A Dual-Polarized Bandwidth Enhanced Filtering Dipole Antenna Design for 5G
IEEE Access, 2023 The present study proposes a dual-polarized bandwidth-enhanced filtering specialized dipole antenna design for 5G by employing a wide printed dipole, filtering resonators, a reflector surface, and specially designed balun structures. Such a configuration

Noncommutative Derivation of the Planck's Radiation Law
Revista Brasileira de Ensino de Física, 2023 The Planck's radiation law for the black body radiation spectrum was capable to explain the experimentally-measured black body spectrum. In order to get this result, Planck proposed his radiation law in a two-fold way: 1) by an ad hoc modification of the

Extreme Electron Acceleration with Fixed Radiation Energy
Entropy, 2022 We examine the extreme situation of radiation from an electron that is asymptotically accelerated to the speed of light, resulting in finite emission energy.

Removing broadside null of symmetric long‐slot antennas by using a coating layer
IET Microwaves, Antennas & Propagation, 2021 This study presents a new concept in the design of symmetric long‐slot leaky‐wave antennas. Theoretically, a radiation null in the broadside direction of these antennas exists.

Mechanism of the X-ray and Soft Gamma-ray Emissions from the High Magnetic Field Pulsar: PSR B1509-58 [PDF]
Journal of Astronomy and Space Sciences, 2013 We use the outer gap model to explain the spectrum and the energy dependent light curves of the X-ray and soft γ-ray radiations of the spin-down powered pulsar PSR B1509-58.

Design of a Cylindrical Crossed Dipole Phased Array Antenna for Weather Surveillance Radars
IEEE Open Journal of Antennas and Propagation, 2021 We present a cylindrical dual-polarization phased array antenna for weather surveillance radars that features high isolation, matched copolar beams, low sidelobe levels, and adaptive null steering.
