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.

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.

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.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Anomalies in bottom from new physics in top

open access: yesPhysics Letters B, 2018
We analyze the possibility to accommodate current b→sℓ+ℓ− anomalies with TeV-scale mediators that couple to right-handed top quarks and muons, contributing to b→sℓ+ℓ− at the one-loop level.

Measurement of single top-quark production in the s-channel in proton–proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A measurement of single top-quark production in the s-channel is performed in proton–proton collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the CERN Large Hadron Collider.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

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 ...
