Global analysis of charm mixing parameters and determination of the CKM angle $γ$

We present an updated global analysis of beauty decays sensitive to the angle $γ$ of the Cabibbo-Kobayashi-Maskawa matrix and of $D$-meson mixing data in the framework of approximate universality, in which CP violation in $D-\overline{D}$ mixing is described in terms of two universal weak phases corresponding to dispersive and absorptive contributions.

Quark-hadron duality violations and higher-order 1/m b corrections in inclusive semileptonic B decays

Journal of High Energy Physics
The theoretical description and data for inclusive semileptonic B decays have reached incredible precision. This motivated us to re-animate the discussion of possible Quark-Hadron Duality violations.

Rest-activity rhythms and cardiovascular events in cardiovascular–kidney–metabolic syndrome: evidence from two nationwide cohorts

American Journal of Preventive Cardiology
Background: Circadian rest–activity rhythm (CRAR) is a modifiable determinant of metabolic and cardiovascular health, yet its role in cardiovascular events and mortality among individuals with cardiovascular–kidney–metabolic (CKM) syndrome remains ...

Outcomes of 39 Canine Eyes Treated With Combined Endoscopic Cyclophotocoagulation and Ahmed Valve Gonioimplantation for Glaucoma

Veterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Purpose To evaluate the long‐term (> 1 year) outcomes of vision and intraocular pressure (IOP) control in dogs with glaucoma undergoing combined endoscopic cyclophotocoagulation (ECP) and Ahmed valve gonioimplantation (AVG). Methods Medical records between 2020 and 2025 were reviewed. Outcomes evaluated included IOP control (< 25 mmHg), vision

Mapping quark-level kinematics to hadrons in a new hybrid model of semileptonic B meson decays

Journal of High Energy Physics
The need to map parton-level processes to color-neutral hadrons in a way that respects quark-hadron duality arises in several areas of physics, including in the semileptonic decays of B mesons.

Why CKM and PMNS Angles Are Not Free Parameters

Why CKM and PMNS Angles Are Not Free Parameters A Geometric Rigidity Principle within the Temporal Theory of the Universe (TTU) In the Standard Model, the CKM and PMNS mixing matrices are introduced as independent empirical inputs, a "free‑angle paradigm" that lacks a dynamical explanation.
