Non-universal $Z'$ from Fluxed GUTs

open access: yes, 2017
We make a first systematic study of non-universal TeV scale neutral gauge bosons $Z'$ arising naturally from a class of F-theory inspired models broken via $SU(5)$ by flux.

Dermoscopic evaluation of normal canine skin with a handheld dermoscope

open access: yesVeterinary Dermatology, Volume 36, Issue 5, Page 593-601, October 2025.
Background – Dermoscopy is a noninvasive diagnostic tool that provides a magnified view of skin structures. While dermoscopy is described for certain canine dermatological diseases, large‐scale studies evaluating normal skin are lacking. Hypothesis/Objective – This study aimed to correlate dermoscopic findings with histopathological results in healthy ...

Testing Newtonian Gravity with AAOmega: Mass-To-Light Profiles and Metallicity Calibrations From 47 Tuc and M55

open access: yes, 2009
Globular clusters are an important test bed for Newtonian gravity in the weak-acceleration regime, which is vital to our understanding of the nature of the gravitational interaction.

A wide-field photometric survey for extratidal tails around five metal-poor globular clusters in the Galactic halo

open access: yes, 2009
Wide-field deep gri images obtained with the Megacam of the Canada-France-Hawaii Telescope (CFHT) are used to investigate the spatial configuration of stars around five metal-poor globular cluster M15, M30, M53, NGC 5053, and NGC 5466, in a field-of-view

CHEMICAL ABUNDANCES IN NGC 5024 (M53): A MOSTLY FIRST GENERATION GLOBULAR CLUSTER

open access: yesThe Astrophysical Journal, 2016
ABSTRACT We present the Fe, Ca, Ti, Ni, Ba, Na, and O abundances for a sample of 53 red giant branch stars in the globular cluster (GC) NGC 5024 (M53). The abundances were measured from high signal-to-noise medium resolution spectra collected with the Hydra multi-object spectrograph on the Wisconsin–Indiana–Yale–NOAO 3.5 m telescope. M53

Persistence of Ancestral KhoeSan Mitochondrial Patterns in Contemporary South African Populations

open access: yesAnnals of Human Genetics, Volume 89, Issue 4, Page 195-207, July 2025.
Abstract Introduction Southern Africa has been inhabited by hunter‐gatherers for at least 20,000 years and has received diverse immigration flows in the last 2000 years. The original inhabitants have interacted with the pastoralist migrants from Eastern Africa (∼2000 ybp), followed by the southern Bantu migration arriving some 1000 ybp, and more ...

On hypercharge flux and exotics in F-theory GUTs [PDF]

open access: yes, 2010
We study SU(5) Grand Unified Theories within a local framework in F-theory with multiple extra U(1) symmetries arising from a small monodromy group. The use of hypercharge flux for doublet-triplet splitting implies massless exotics in the spectrum that ...

Metabolite‐Based Network Pharmacology, Molecular Docking, and Dynamics Simulations to Preliminarily Verify Treating Diabetic Encephalopathy Effect of Kuwanon G

open access: yesFood Science &Nutrition, Volume 13, Issue 6, June 2025.
This study investigates the neuroprotective effects of Kuwanon G (KWG) against diabetic encephalopathy (DE) by characterizing its metabolic profile and therapeutic mechanisms. Using UHPLC‐Q‐TOF‐MS, network pharmacology, molecular docking, and dynamics simulations, 56 metabolites were identified, with nine showing high intestinal absorption and ...

Hydromethylthionine sustains truncated tau‐dependent inflammation‐lowering effects in mouse brain

open access: yesThe FEBS Journal, Volume 292, Issue 10, Page 2602-2623, May 2025.
Hydromethylthionine (HMT) is an inhibitor of tau protein aggregation, but one that appears to be affected in subjects already receiving symptomatic treatments for dementia, such as memantine. We found that HMT decreased both tau aggregation and neuroinflammation in transgenic mice in a manner that was unaffected by memantine.
