Deep learning in the detection of early inflammatory signs in rheumatoid arthritis

Y. -X. Li

In this study, we have developed a series of models and methods for quantifying inflammation, predicting future RA development, interpreting DL models, aggregating information to reach population-level conclusions, and combining all these methods to discover potential new imaging biomarkers that contribute to …

Spectral localisers and aperiodic topological phases in noncommutative geometry

Y. -X. Li

The dissertation offers new tools and insights to computation and modelling of topological phases, with an emphasis on the aperiodic setting. The first part develops an abstract mathematical framework for computing topological invariants of quantum systems using finite spectral data, and provides …

Qcombo: A Python Package for Automated Commutator Calculations of Quantum Many-Body Operators

L. H. Chen, Y. -X. Li, H. Hergert, J. M. Yao

qcombo is a Python package for the symbolic evaluation of commutators between general quantum many-body operators expressed in normal-ordered form using the generalized Wick theorem. The package provides an automated and systematic framework for generating the corresponding algebraic expressions, significantly reducing the …

Cross Section Measurements of $\bar{n}p \rightarrow K^{+}K^{-}π^{+}(π^{0})$ via Antineutrons Produced by $J/ψ\to p π^{-} \bar{n}$ Decays

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Based on a novel method for producing antineutrons via $J/ψ$ decays, we report a study of $\bar{n}p$ inelastic scattering into final states containing kaons. The analysis uses $(10087\pm44)\times 10^6$ $J/ψ$ events collected at the BESIII detector operating at the BEPCII storage ring. …

Search for the decay $B^+ \rightarrow K^+τ^+τ^-$ using data from the Belle and Belle II experiments

Belle, Belle Collaborations, :, M. Abumusabh et autres

We report a search for the rare decay $B^{+} \rightarrow K^{+} τ^{+} τ^{-}$ using $1.2 \times 10^9$ $Υ(4S)$ mesons produced near threshold in electron-positron collisions and collected by the Belle and Belle~II experiments. We fully reconstruct the hadronic decay of one $B$ …

$B$-jet fragmentation with $B^{\pm} \to J/ψK^{\pm}$ decays in $\sqrt{s} = 13$ TeV $pp$ collisions at LHCb

LHCb Collaboration, R. Aaij, A. S. W. Abdelmotteleb, C. Abellan Beteta et autres

The collinear and transverse-momentum-dependent jet fragmentation function and the radial profile for $B^{\pm}$ mesons in jets are measured. The $B^{\pm}$ mesons are reconstructed through the $J/ψ(\to μ^{+} μ^{-}) K^{\pm}$ decay channel using proton-proton collision data collected during 2016-2018 with the LHCb detector …

Scintillation light calibrations, systematic uncertainties, and triggering efficiency in the MicroBooNE detector

MicroBooNE collaboration, P. Abratenko, D. Andrade Aldana, L. Arellano et autres

Scintillation light, produced alongside ionisation charge from particle interactions, plays a critical role in liquid argon time projection chamber (LArTPC) detectors. A detailed understanding of its production and detection mechanisms is essential for robust calibration, systematic uncertainty evaluation, and physics analysis. This …

Search for the radiative decays $D^0\to γ\bar K_1(1270)^0$ and $D^+\to γK_1(1270)^+$

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

A search for the radiative decays $D^0\to γ\bar K_1(1270)^0$ and $D^+\to γK_1(1270)^+$ is conducted using $20.3~\mathrm{fb}^{-1}$ of $e^+e^-$ annihilation data collected at the center-of-mass energy $\sqrt{s}=3.773$ GeV by the BESIII detector operating at the BEPCII collider. No significant signals are observed, and …

The full evolution of the type-C QPO in MAXI J1348-630 revealed by Insight-HXMT

X. -L. Wang, Z. Yan, F. -G. Xie, J. -F. Wang et autres

Based on abundant data from Insight-HXMT, we conducted a detailed analysis of type-C quasi-periodic oscillations (QPOs) in the black hole X-ray binary MAXI J1348-630. Type-C QPOs were intensively detected over a broad energy band, with frequencies ranging from 0.24 to 10.3 Hz, …

Measurement of CP asymmetry in D0 → KS0KS0 decays with Run 3 data

R. Aaij, A. S. W. Abdelmotteleb, C. Abellan Beteta, F. Abudinén et autres

A measurement of CP asymmetry in D0 → KS0KS0 decays is reported, based on a data sample of proton-proton collisions collected with the LHCb detector in 2024 at a centre-of-mass energy of 13.6 TeV , corresponding to an integrated luminosity of 6.2 …

All-sky Searches for Continuous Gravitational Waves from Isolated Neutron Stars in the Data from the First Part of the Fourth LIGO-Virgo-KAGRA Observing Run

A. Abac, I. Abouelfettouh, F. Acernese, K. Ackley et autres

Gravitational waves can be gravitationally lensed by massive objects along their path. Depending on the lens mass and the lens--source geometry, this can lead to the observation of a single distorted signal or multiple repeated events with the same frequency evolution. We …
