Means of Employing Radiation Nulls in Filtennas: A Review

open access: yesIEEE Access
In this paper, methods for improving frequency selectivity in filter antennas by employing controllable radiation nulls (RN) are reviewed. Radiation nulls in the Gain graph help in improving the rejection of out-of-band frequencies.

Macrophage derived VEGF regulates macrophage senescence to inhibit radiation-induced dermatitis [PDF]

open access: yesJournal of Translational Medicine
Background 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.

Radiation Hardened NULL Convention Logic Asynchronous Circuit Design

open access: yesJournal of Low Power Electronics and Applications, 2015
This paper proposes a radiation hardened NULL Convention Logic (NCL) architecture that can recover from a single event latchup (SEL) or single event upset (SEU) fault without deadlock or any data loss.

Inference under outcome misclassification in health risk models using a simulation study with a validation dataset [PDF]

open access: yesScientific Reports
Death certificates are commonly used in epidemiological studies investigating the relationship between exposure and health outcomes. It is known that death certificates may misclassify the underlying causes of death, and it is commonly understood that if

A Dual-Polarized Bandwidth Enhanced Filtering Dipole Antenna Design for 5G

open access: yesIEEE 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

Scoping the characteristics and benefits of a connected double-null configuration for power exhaust in EU-DEMO

open access: yesNuclear Materials and Energy, 2021
A double-null configuration is being considered for the EU-DEMO, due to its potential benefits for power exhaust arising from the use of two active divertors and magnetically disconnected low- and high-field sides.

Null radiation zone at the LHC [PDF]

open access: yesPhysical Review D, 2013
The null radiation zone theorem states that, when special kinematical conditions are satisfied, all the helicity amplitudes of a parton-level subprocess where a vector current is emitted vanish due to destructive interference among different diagrams. We study the manifestation of the theorem in $pp$ collisions at the $\sqrt{s}=8$ TeV LHC.

Noncommutative Derivation of the Planck's Radiation Law

open access: yesRevista 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

Two Classes of Solutions of Null Electromagnetic Radiation [PDF]

open access: yesProgress of Theoretical Physics, 1972
2) con­ ditions so that the null field under investigation may be said to be generated by matter free electromagnetic radiation. The line element in both cases has been chosen to be such that one of the coordinate axes (say, x 1 axis) is along the null direction or in other words gn = 0.
