Quantum phase transition for the BEC-BCS crossover in condensed matter physics and CPT violation in elementary particle physics [PDF]

, 2004
We discuss the quantum phase transition that separates a vacuum state with fully gapped fermion spectrum from a vacuum state with topologically protected Fermi points (gap nodes).

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Strip-based Scintillation Detector for Dual-readout High-granularity Calorimetry [PDF]

EPJ Web of Conferences
New calorimeter technology is being developed for future collider experiments. We are developing a calorimeter that integrates two technologies, a high-granularity calorimeter and a dual-readout calorimeter, and has high time resolution at a picosecond ...

Berberine–cinnamic acid co‐crystal effect in ameliorating hyperlipidemia might be regulated through the PI3K/AKT/mTOR/SREBP‐1 signaling pathway

FEBS Open Bio, EarlyView.
Berberine–cinnamic acid co‐crystal (BBR‐CA) inhibits the phosphorylation of the phosphatidylinositol 3‐kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway, suppressing the transfer of pre‐sterol regulatory element‐binding proteins‐1 (SREBP‐1) from the endoplasmic reticulum to the nucleus. This results in a decrease in the expression level of

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Texture zero neutrino models and their connection with resonant leptogenesis

Nuclear Physics B, 2018
Within the low scale resonant leptogenesis scenario, the cosmological CP asymmetry may arise by radiative corrections through the charged lepton Yukawa couplings.

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

FEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Spontaneous CP breaking in a QCD-like theory

Journal of High Energy Physics
We examine the phase structure of a QCD-like theory at θ ¯ $$ \overline{\theta} $$ = π obtained from supersymmetric SU(N) QCD perturbed by a small amount of supersymmetry breaking via anomaly mediation (AMSB QCD). The spectrum of this theory matches that

TMDlib2 and TMDplotter: a platform for 3D hadron structure studies

European Physical Journal C: Particles and Fields, 2021
A common library, TMDlib2, for Transverse-Momentum-Dependent distributions (TMDs) and unintegrated parton distributions (uPDFs) is described, which allows for easy access of commonly used TMDs and uPDFs, providing a three-dimensional (3D) picture of the ...

Introducing an innovative approach of teaching the Standard Model of particle physics at high school

Journal of Physics: Conference Series, 2019
The role that is assigned to elementary particle physics in high school education differs all over the world. Even within a single country like Germany there are major differences in the depth of discussion.
