Quasi-periodic oscillations and reflection feature evolution in 4U 1630-47 observed with Insight-HXMT
The Galactic black hole (BH) X-ray binary 4U 1630-47 went into a new outburst in 2021 after $\sim$ 600 days from its 2020 outburst. We perform a detailed analysis of quasi-periodic oscillations and spectral evolutions during its 2021 outburst based on \textit{Insight}-HXMT observations. The main science aims to study the reflection features evolution of this accreting black hole using the observations of detecting quasi-periodic oscillations (QPOs) and quasi-regular modulations (QRMs). The QPOs…

Rovibrational computations for He$_2^+$ X$^+\ Σ_\mathrm{u}^+$ including non-adiabatic, relativistic and QED corrections
We report the potential energy curve, the diagonal Born-Oppenheimer, non-adiabatic mass, relativistic, and leading-order QED corrections for the ground electronic state of the helium dimer cation; the higher-order QED and finite-nuclear size effects are also estimated. The computations are carried out with an improved error control and over a much broader configuration range compared to earlier work [D. Ferenc, V. I. Korobov, and E. Mátyus, Phys. Rev. Lett. 125, 213001 (2020)]. As a result, al…

Last leg on our brief history of NLP (so far) is the advent of large language models with GPT-3 in 2020 and the introduction of learning from the prompt (aka few-shot learning).

Enhancing air-shower observations: Results from an IceCube Surface Array Prototype Station
The Surface Array Enhancement of the IceCube Neutrino Observatory is set to equip the existing surface cosmic-ray array of ice-Cherenkov detectors, IceTop, with radio antennas and scintillation detectors. This can lower the energy threshold of detection and increase the measurement accuracy of IceTop. The antenna readout uses a multiplicity trigger from the scintillation detectors. A fully functioning prototype station of the enhancement was deployed at the South Pole in 2020 and upgraded in 20…

A note on multi-transitivity in non-autonomous discrete systems
This paper is concerned with some stronger forms of transitivity in non-autonomous discrete systems$(f_{ 1,\infty})$ generated by a uniformly convergent sequence of continuous self maps. Firstly, we present two counterexamples to show that Theorem 3.1 obtained by Salman and Das in [Multi-transitivity in nonautonomous discrete systems Topol. Appl. 278(2020)107237] is not true. Then, we introduce and study mildly mixing in non-autonomous discrete systems, which is stronger than mixing. We obtain …
