Event-by-Event Fluctuations of Particle Ratios in Heavy-Ion Collisions

open access: yes, 2006
We study event-by-event dynamical fluctuations of various particle ratios at different energies. We assume that particle production in final state is due to chemical equilibrium processes.

The apo LETM1 F‐EF‐hand adopts a closed conformation that underlies a multi‐modal sensory role in mitochondria

open access: yesFEBS Letters, EarlyView.
We present the first solution structure of the Ca2+‐depleted LETM1 F‐EF‐hand through a D676A/N678A Ca2+ binding‐deficient mutant, revealing a closed hydrophobic cleft caused by a unique F1‐helix pivot. The apo LETM1 F‐EF‐hand exhibits regiospecific hot and cold unfolding, sensitivity to physiological pH changes and potential for promiscuous heterotypic

Multiplicity-dependent production of Σ(1385) ± and Ξ(1530)0 in pp collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics
The production yields of the Σ(1385) ± and Ξ(1530)0 resonances are measured in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with ALICE. The measurements are performed as a function of the charged-particle multiplicity ⟨dN ch /dη⟩, which is related to the ...

A search for new resonances in multiple final states with a high transverse momentum Z boson in s $$ \sqrt{s} $$ = 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A generic search for resonances is performed with events containing a Z boson with transverse momentum greater than 100 GeV, decaying into e + e − or μ + μ − . The analysed data collected with the ATLAS detector in proton-proton collisions at a centre-of-

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Light-flavor particle production in high-multiplicity pp collisions at s $$ \sqrt{\textrm{s}} $$ = 13 TeV as a function of transverse spherocity

open access: yesJournal of High Energy Physics
Results on the transverse spherocity dependence of light-flavor particle production (π, K, p, ϕ, K*0, K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ , Λ, Ξ) at midrapidity in high-multiplicity pp collisions at s $$ \sqrt{s} $$ = 13 TeV were obtained with the ...

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

Investigating strangeness enhancement with multiplicity in pp collisions using angular correlations

open access: yesJournal of High Energy Physics
A study of strange hadron production associated with hard scattering processes and with the underlying event is conducted to investigate the origin of the enhanced production of strange hadrons in small collision systems characterised by large charged ...

Parametric Resonance in an Expanding Universe [PDF]

open access: yes, 1997
Parametric resonance has been discussed as a mechanism for copious particle production following inflation. Here we present a simple and intuitive calculational method for estimating the efficiency of parametric amplification as a function of parameters.

Understanding and measuring mechanical signals in the tumor stroma

open access: yesFEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...
