Tri-unification: a separate SU(5) for each fermion family

Journal of High Energy Physics
In this paper we discuss SU(5)3 with cyclic symmetry as a possible grand unified theory (GUT). The basic idea of such a tri-unification is that there is a separate SU(5) for each fermion family, with the light Higgs doublet(s) arising from the third ...

Autonomous Implants

Advanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Radiative mass mechanism: addressing the flavour hierarchy and strong CP puzzle

Journal of High Energy Physics
We propose a class of models based on the parity invariant Left-Right Symmetric Model (LRSM), which incorporates the mechanism of radiative generation of fermion masses while simultaneously possessing the solution to the Strong CP problem.

Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

Advanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

The Standard Model quark/lepton masses and the Cabibbo-Kobayashi-Maskawa mixing in an SU(8) theory

Journal of High Energy Physics
The observed Standard Model (SM) quark/lepton mass hierarchies and the Cabibbo-Kobayashi-Maskawa (CKM) mixing pattern are described in an SU(8) theory through its realistic symmetry breaking pattern with three intermediate stages, which rely on a set of ...

NLO Corrections to lepton pair production beyond the Standard Model at hadron colliders

, 2005
We consider lepton pair production at a hadron collider in a class of effective theories with the relevant operators being four-fermion contact interaction.

Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

Advanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.

Intracellular Monitoring of Luminescent Ag2S Nanoparticles in Fibroblasts

Advanced Optical Materials, EarlyView.
This study investigates the long‐term luminescence behavior of Ag2S quantum dots (AS QDs) with three surface ligands (DTDTPA, 11MUA, PEG) in fibroblasts over 9 days. AS‐PEG showed stable uptake and enhanced NIR‐II emission, while others decreased due to oxidative stress.

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...
