Deep Learning for Detecting Dental Plaque and Gingivitis From Oral Photographs: A Systematic Review

Community Dentistry and Oral Epidemiology, Volume 53, Issue 6, Page 617-632, December 2025.
ABSTRACT Objectives This systematic review aimed to evaluate the performance of deep learning (DL) models in detecting dental plaque and gingivitis from red, green, and blue (RGB) intraoral photographs. Methods A comprehensive literature search was conducted across Medline, Scopus, Embase, and Web of Science databases up to January 31, 2025.

Fresh Activity in Old Systems: Radio AGN in Fossil Groups of Galaxies

, 2012
We present the first systematic 1.4 GHz Very Large Array radio continuum survey of fossil galaxy group candidates. These are virialized systems believed to have assembled over a gigayear in the past through the merging of galaxy group members into a ...

A translated utopia: Embodied communication, media ideologies, and Star Trek's Universal Translator

Journal of Linguistic Anthropology, Volume 35, Issue 3, December 2025.
Abstract This paper uses Star Trek's “Universal Translator” (UT) as a point of departure for considering the imagined future of mediated linguistic interactions and of contact across difference. Although such a technology does not exist, taking its potentialities seriously as folkloric devices allows for an exploration of ideologies relating to ...

Constraining Annihilating Dark Matter Using the Multifrequency Radio Flux Profiles of the M33 Galaxy

The Astrophysical Journal
Radio data can give stringent constraints for annihilating dark matter. In general, radio observations can detect very accurate radio flux density with high resolution and different frequencies for nearby galaxies.

Climate Emergency and Different Ways to Fail? The Fermi Paradox, the Simulation Hypothesis, Agency and Hope

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.
ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest the problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

A Linearly Polarized Merger Shock Down to 550 MHz: A uGMRT Study of the Merging Cluster A746

The Astrophysical Journal
Radio relics, arc-like polarized sources with highly aligned magnetic fields, are typically found on the outskirts of merging galaxy clusters. The magnetoionic media responsible for the significant coherence observed in radio relics remain poorly ...

On the connection between giant radio halos and cluster mergers

, 2010
The frequently observed association between giant radio halos and merging galaxy clusters has driven present theoretical models of non-thermal emission from galaxy clusters, which are based on the idea that the energy dissipated during cluster-cluster ...

The simplicity of physical laws

Noûs, Volume 59, Issue 4, Page 957-987, December 2025.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

3D Localization of FRB 20190425A for Its Potential Host Galaxy and Implications

The Astrophysical Journal
Fast radio bursts (FRBs) are high-energy, short-duration phenomena in radio astronomy. Identifying their host galaxies can provide insights into their mysterious origins. In this paper, we introduce a novel approach to identifying potential host galaxies

RAD@home Citizen Science Discovery of Two Spiral Galaxies Where the 30–220 kpc Radio Lobes Are Possibly Shaped by Ram Pressure Stripping

Galaxies
We report the RAD@home citizen science discovery of two rare spiral-host radio galaxies (NGC 3898 and WISEA J221656.57-132042434.1 or RAD-“Thumbs up” galaxy), both exhibiting asymmetric radio lobes extending over 30 to 220 kiloparsec scales. We present a
