Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Natural Qubit Matrix of Primary Elements of Matter

open access: yesMATEC Web of Conferences, 2018
The arithmetic limits of natural bit calculations are strictly established. The natural quantum metric system has been developed. Only seven scaling units that generate thirteen invariant values are necessary and sufficient for an accurate estimation and

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Invariant mass reconstruction of heavy gauge bosons decaying to $$\tau $$ τ leptons using machine learning techniques

open access: yesEuropean Physical Journal C: Particles and Fields
Many analyses are performed by the LHC experiments to search for heavy gauge bosons, which appear in several new physics models. The invariant mass reconstruction of heavy gauge bosons is difficult when they decay to $$\tau $$ τ leptons due to missing ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Search for periodic signals in the dielectron and diphoton invariant mass spectra using 139 fb −1 of pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for physics beyond the Standard Model inducing periodic signals in the dielectron and diphoton invariant mass spectra is presented using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. Novel

W+Jets at CDF: Evidence for Top Quarks

open access: yes, 2011
Recently, an anomaly of W+jets events at large invariant masses has been reported by CDF. Many interpretations as physics beyond the Standard Model are being offered.

Dual DSR [PDF]

open access: yes, 2011
We develop the physics of dual kappa Poincare algebra, which we will call dual DSR. First, we show that the dual kappa Poincare algebra is isomorphic to de Sitter algebra and its spactime is essentially de Sitter spacetime.

Approximate Constancy of Adiabatic Invariants in Plasma Physics [PDF]

open access: yesProgress of Theoretical Physics, 1962
The interaction representation for classical mechanics starting from an operational formulation of the same is presented. General criteria to be satisfied by a slowly time-dependent Hamiltonian in order to possess adiabatic invariants of the m-th order are given.
