Observation of e + e − → ηψ(2S) at center-of-mass energies from 4.236 to 4.600 GeV

open access: yesJournal of High Energy Physics, 2021
Using a total of 5.25 fb −1 of e + e − collision data with center-of-mass energies from 4.236 to 4.600 GeV, we report the first observation of the process e + e − → ηψ(2S) with a statistical significance of 4.9 standard deviations.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Evidence for Planck-scale resonant particle production during inflation from the CMB power spectrum [PDF]

open access: yesThe Fourteenth Marcel Grossmann Meeting, 2017
The power spectrum of the cosmic microwave background from both the {\it Planck} and {\it WMAP} data exhibits a slight dip for multipoles in the range of $l= 10-30$. We show that such a dip could be the result of the resonant creation of massive particles that couple to the inflaton field.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Production of Dark Sector Particles via Resonant Positron Annihilation on Atomic Electrons

open access: yesPhysical Review Letters
Resonant positron annihilation on atomic electrons provides a powerful method to search for light new particles coupled to e+e−. Reliable estimates of production rates require a detailed characterization of electron momentum distributions. We describe a general method that harnesses the target material Compton profile to properly include electron ...

Choroid Plexus Enlargement and USPIO‐Based Inflammatory Feature in Cerebral Small Vessel Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The choroid plexus (CP) is a key component of the blood–cerebrospinal fluid barrier (BCSFB), but its mechanism of action in cerebral small vessel disease (CSVD) remains unclear. This study investigated CP volume (CPV) alterations and their association with conventional imaging markers in CSVD and explored the underlying role of ...

Measurement of e + e − → ωη′ cross sections at s $$ \sqrt{s} $$ = 2.000 to 3.080 GeV

open access: yesJournal of High Energy Physics
We measured the Born cross sections for the process e + e − → ωη′ at 22 center-of-mass energies from 2.000 to 3.080 GeV with the BESIII detector at the BEPCII collider. We observed a resonant structure with a statistical significance of 9.6σ.
