PKCζ and JNK signaling regulate radiation-induced compensatory proliferation in parotid salivary glands.

PLoS ONE, 2019
Radiotherapy is a common treatment option for head and neck cancer patients; however, the surrounding healthy salivary glands are often incidentally irradiated during the process.

Quantum fields during black hole formation: how good an approximation is the Unruh state?

Journal of High Energy Physics, 2018
We study the quantum effects of a test Klein-Gordon field in a Vaidya space-time consisting of a collapsing null shell that forms a Schwazschild black hole, by explicitly obtaining, in a (1 + 1)-dimensional model, the Wightman function, the renormalised ...

Scanning circular array with null constraints onthe radiation pattern

Electronics Letters, 1996
The authors examine the problem of using a circular antenna array to scan a given radiation pattern over an angular sector of the array plane, while satisfying null constraints at prescribed directions of interference. We solve the problem using an algorithm based on the discrete Fourier transform.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Null-like constraints in the Einstein–Hilbert action and their cosmological implications

Physics Letters B
Motivated by the fact that radiation propagates along null trajectories, we introduce a geometric constraint into the Einstein–Hilbert action via the method of Lagrange multipliers.

Null infinity as an open Hamiltonian system

Journal of High Energy Physics, 2021
When a system emits gravitational radiation, the Bondi mass decreases. If the Bondi energy is Hamiltonian, it can thus only be a time-dependent Hamiltonian. In this paper, we show that the Bondi energy can be understood as a time-dependent Hamiltonian on

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

Advanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

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

Journal 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.
