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 PHYSICS RESULTS AT CDF [PDF]

open access: yesFundamental Interactions, 2006
The most recent results on top quark physics at CDF are reported. Measurements of cross-section and mass are presented, and the status of single top quark production searches are discussed. The results obtained from probing various top quark properties are also presented.

Phenomenology of a light gluon resonance in top-physics at Tevatron and LHC [PDF]

open access: yes, 2011
We present a phenomenological analysis of the recent Tevatron results on the $ t\overline t $ forward-backward asymmetry and invariant-mass spectrum assuming a new contribution from an s-channel gluon resonance with a mass in the range from 700 to 2500 ...

Inclusive and differential cross section measurements of single top quark production in association with a Z boson in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
Inclusive and differential cross sections of single top quark production in association with a Z boson are measured in proton-proton collisions at a center-of-mass energy of 13 TeV with a data sample corresponding to an integrated luminosity of 138 fb −1

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.

Implications of the CDF $t\bar{t}$ forward–backward asymmetry for boosted top physics [PDF]

open access: yes, 2011
New physics at a high scale Λ can affect top-related observables at O ( 1 / Λ 2 ) via the interference of effective four quark operators with the SM amplitude.

Measurement of the top quark pole mass using t t ¯ $$ \textrm{t}\overline{\textrm{t}} $$ +jet events in the dilepton final state in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2023
A measurement of the top quark pole mass m t pole $$ {m}_{\textrm{t}}^{\textrm{pole}} $$ in events where a top quark-antiquark pair ( t t ¯ $$ \textrm{t}\overline{\textrm{t}} $$ ) is produced in association with at least one additional jet ( t t ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Full quantum tomography of top quark decays [PDF]

open access: yesPhysics Letters B
Quantum tomography in high-energy physics processes has usually been restricted to the spin degrees of freedom. We address the case of top quark decays $t \to W b$, in which the orbital angular momentum ($L$) and the spins of $W$ and $b$ are intertwined ...

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.
