A Review of Ga₂O₃ Heterojunctions for Deep‐UV Photodetection: Current Progress, Methodologies, and Challenges

Advanced Electronic Materials, Volume 11, Issue 9, June 2025.
This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges

Cloud and Star Formation in Spiral Arms

, 2014
We present the results from simulations of GMC formation in spiral galaxies. First we discuss cloud formation by cloud-cloud collisions, and gravitational instabilities, arguing that the former is prevalent at lower galactic surface densities and the ...

In Vitro Validation of Pulsed Electromagnetic Field (PEMF) as an Effective Countermeasure Against Inflammatory‐Mediated Intervertebral Disc Degeneration

JOR SPINE, Volume 8, Issue 2, June 2025.
ABSTRACT Background Intervertebral disc (IVD) degeneration (IDD) is the main contributor to chronic low back pain (LBP), the leading cause of disability worldwide, with a significant impact on the quality of life and health of common people. The etiology of IDD is still unclear, but it has been largely demonstrated the crucial role of inflammation and ...

Soft band X/K luminosity ratios in late-type galaxies and constraints on the population of supersoft X-ray sources

, 2010
We study X-ray to K-band luminosity ratios (L_X/L_K) of late-type galaxies in the 0.3-0.7 keV energy range. From the Chandra archive, we selected nine spiral and three irregular galaxies with point source detection sensitivity better than 5 x 10^36 erg/s

Plant‐Based Mycetoma Inhibitors Targeting the 50S Ribosomal Protein of Nocardia brasiliensis: In Silico Approach

ChemistrySelect, Volume 10, Issue 21, June 4, 2025.
In‐silico drug discovery pipeline for Mycetoma caused by Nocardia brasiliensis. A library of 1034 phytocompounds was screened to identify potent inhibitors, with Parviflorone F showing strong binding and stability against the 50S ribosomal unit. Molecular dynamics confirmed its inhibitory potential, offering a promising therapeutic candidate.

Temporal Dynamics With and Without a Nervous System: Plant Physiology, Communication, and Movement

Cognitive Science, Volume 49, Issue 6, June 2025.
Abstract The concept of time has long been the subject of complex philosophical reflections and scientific research, which have interpreted it differently based on the starting question, context, and level of analysis of the system under investigation.

Unique starch biosynthesis pathways in wild rice revealed by multi‐omics analyses

Plant Biotechnology Journal, Volume 23, Issue 6, Page 2429-2445, June 2025.
Summary Australian wild rice species (AWS) possess unique starch properties characterized by a slow digestibility rate. However, the genomic and transcriptomic variations of starch‐synthesis‐related genes (SSRGs) influencing starch physiochemical properties in AWS remain unclear.

Spiral arm crossings inferred from ridges in Gaia stellar velocity distributions

, 2018
The solar neighborhood contains disc stars that have recently crossed spiral arms in the Galaxy. We propose that boundaries in local velocity distributions separate stars that have recently crossed or been perturbed by a particular arm from those that ...

Nuclear Spirals as Signatures of Supermassive Black Holes

, 2004
Recent high resolution images of spiral galaxies show wide varieties of features including nuclear spirals in the central parts. Some of the galaxies show grand-design nuclear spirals.
