Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Top-quark physics at the CLIC electron-positron linear collider

open access: yesJournal of High Energy Physics, 2019
The Compact Linear Collider (CLIC) is a proposed future high-luminosity linear electron-positron collider operating at three energy stages, with nominal centre-of-mass energies s $$ \sqrt{s} $$ = 380 GeV, 1.5 TeV, and 3 TeV.

Search for leptonic charge asymmetry in t t ¯ W $$ t\overline{t}W $$ production in final states with three leptons at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2023
A search for the leptonic charge asymmetry ( A c ℓ $$ {A}_{\textrm{c}}^{\ell } $$ ) of top-quark-antiquark pair production in association with a W boson ( t t ¯ W $$ t\overline{t}W $$ ) is presented.

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+.

TOP QUARK PHYSICS AT THE TEVATRON [PDF]

open access: yesInternational Journal of Modern Physics A, 2013
The heaviest known elementary particle, the top quark, was discovered in 1995 by the CDF and D0 collaborations at the Tevatron proton–antiproton collider at Fermilab. Since its discovery, a large program was set in motion by the CDF and D0 collaborations to characterize the production and decay properties of top quarks, and investigate their potential ...

Effective Field Theory for Top Quark Physics [PDF]

open access: yes, 2010
Physics beyond the standard model can affect top-quark physics indirectly. We describe the effective field theory approach to describing such physics, and contrast it with the vertex-function approach that has been pursued previously.

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.

Energy-peak based method to measure top quark mass via B-hadron decay lengths

open access: yesJournal of High Energy Physics, 2023
We develop a method for the determination of the top quark mass using the distribution of the decay length of the B-hadrons originating from its decay. This technique is based on our earlier observation regarding the location of the peak of the b quark ...
