Optimal deep learning activity recognition pipeline using animal bio‐logging data
Methods in Ecology and Evolution, EarlyView.Abstract Animal activity recognition using supervised machine learning on bio‐logging data has revolutionized behavioural studies on wildlife and livestock over the past decade. These studies' analytic pipelines differ substantially though, being based on various sensors, features, algorithms and hyperparameter values, which has caused suboptimal or ...

Acta Physica Polonica B Proceedings Supplement, 2017 We discuss cold dense QCD by examining constraints from neutron stars, nuclear experiments, and QCD calculations at low and high baryon density. The two solar mass constraint and suggestive small radii (10~13 km) of neutron stars constrain the strength of hadron-quark matter phase transitions.

On-shelļ methods for perturbative QCD [PDF]
, 2006 We present new on-shell techniques for the calculation of colour ordered helicity amplitudes in QCD. We review the methods of on-shell recursion and the MHV rules before applying them to tree-level processes within the Standard Model.

The high-energy limit of perturbative QCD: Theory and phenomenology [PDF]
, 2022 After a brief introduction of formal and phenomenological progresses in the study of the high-energy limit of perturbative QCD, we present arguments supporting the statement that the inclusive emission of Higgs bosons or heavy-flavored hadrons acts as ...

Decay-protected superconducting qubit with fast control enabled by integrated on-chip filters
Communications PhysicsAchieving fast gates and long coherence times for superconducting qubits presents challenges, typically requiring either a stronger coupling of the drive line or an excessively strong microwave signal to the qubit.

A matrix model for QCD: QCD color is mixed [PDF]
International Journal of Modern Physics A, 2015 We use general arguments to show that colored QCD states when restricted to gauge invariant local observables are mixed. This result has important implications for confinement: a pure colorless state can never evolve into two colored states by unitary evolution. Furthermore, the mean energy in such a mixed colored state is infinite.
