Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

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+.

Offline data processing system of the BESIII experiment

open access: yesEuropean Physical Journal C: Particles and Fields
The BESIII experiment has been operating since 2009 and has received several upgrades, to study the $$\tau $$ τ -charm physics utilizing the BEPCII accelerator. The BEPCII is a double-ring multi-bunch collider with a luminosity of $$1 \times 10^{33} \, {\

Measurement of e+e − → K+K − π 0 cross section and observation of a resonant structure

open access: yesJournal of High Energy Physics, 2022
Based on e + e − collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e + e − → K + K − π 0.

Strongly Coupled Plasmas in High-Energy Physics

open access: yes, 2003
One of the main activities in high-energy and nuclear physics is the search for the so-called quark-gluon plasma, a new state of matter which should have existed a few microseconds after the Big Bang.

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 e + e − → ωπ + π − cross section at s $$ \sqrt{s} $$ = 2.000 to 3.080 GeV

open access: yesJournal of High Energy Physics, 2023
A partial wave analysis on the process e + e − → ωπ + π − is performed using 647 pb −1 of data sample collected by using the BESIII detector operating at the BEPCII storage ring at center-of-mass (c.m.) energies from 2.000 GeV to 3.080 GeV.

Development of an automatic calibration system for beam position monitor

open access: yesHe jishu, 2022
BackgroundBeam position monitor (BPM) is an important beam measurement component of accelerators, and it generally needs to be calibrated before online operating. High energy photon source (HEPS) and upgrade of Beijing electron positron collider (BEPCII)

Energy peaks: a high energy physics outlook

open access: yes, 2017
Energy distributions of decay products carry information on the kinematics of the decay in ways that are at the same time straightforward and quite hidden.
