Renormalization and Scale Evolution of the Soft-Quark Soft Function [PDF]
, 2020 Soft functions defined in terms of matrix elements of soft fields dressed by Wilson lines are central components of factorization theorems for cross sections and decay rates in collider and heavy-quark physics. While in many cases the relevant soft functions are defined in terms of gluon operators, at subleading order in power counting soft functions ...

Next-to-leading power two-loop soft functions for the Drell-Yan process at threshold [PDF]
, 2021 We calculate the generalized soft functions at $\mathcal{O}(\alpha_s^2)$ at next-to-leading power accuracy for the Drell-Yan process at threshold. The operator definitions of these objects contain explicit insertions of soft gauge and matter fields, giving rise to a dependence on additional convolution variables with respect to the leading power result.

Rigid-Soft Interactive Learning for Robust Grasping [PDF]
, 2020 Inspired by widely used soft fingers on grasping, we propose a method of rigid-soft interactive learning, aiming at reducing the time of data collection. In this paper, we classify the interaction categories into Rigid-Rigid, Rigid-Soft, Soft-Rigid according to the interaction surface between grippers and target objects.

Soft Power Determinants in the World and Implications for China
The Copenhagen Journal of Asian Studies, 2020 Statistical tests are here conducted on two explanations of soft power. One is Joseph Nye's argument that political values, foreign policy and cultural appeals shape soft power, and the other is the positive peace argument which suggests a significant ...

States Soft Power Utilization in the Twenty-First Century: Pros and Cons from the Nigerian Perspective [PDF]
Journal of Public Administration and Development Alternatives, 2020 This article analyses the challenges that Nigeria is confronted with in regard to its potential and utilization of soft power. The utilization of soft power among state actors has become a dominant feature in international relations. The expensive nature

Record volumetric activities of oxygen electroreduction in partly packing graphene/AgTCNQ electrodes
Carbon Trends, 2023 Volumetric activity is the key to success in many space-constrained electrochemical devices. However, the state-of-the-art volumetric activities for oxygen electroreduction to hydrogen peroxide only achieve up to 30.8 mg cm−3 h−1. This is attributable to

On Power Suppressed Operators and Gauge Invariance in SCET [PDF]
, 2003 The form of collinear gauge invariance for power suppressed operators in the soft-collinear effective theory is discussed. Using a field redefinition we show that it is possible to make any power suppressed ultrasoft-collinear operators invariant under ...

Nature of the Soft Spectral Component in the X-ray Pulsars SMC X-1 and LMC X-4 [PDF]
, 2002 We present here the results of an investigation of the pulse averaged and pulse phase resolved energy spectra of two high luminosity accretion powered X-ray pulsars SMC X-1 and LMC X-4 made with ASCA. The phase averaged energy spectra definitely show the

A Physical Model for the X-ray Time Lags of Narrow Line Seyfert Type 1 Active Galactic Nuclei [PDF]
, 2014 We study the origin of the soft X-ray excess seen in the 'simple' Narrow Line Seyfert 1 galaxy PG1244+026 using all available spectral-timing information. This object shows the standard switch between soft leading the hard band on long timescales, to the opposite behaviour on short timescales.
