We study the small speed of light expansion general relativity, utilizing modern perspective on non-Lorentzian geometry. This is an around ultra-local Carroll limit, in which cones close up. To this end, we first rewrite Einstein-Hilbert action pre-ultra-local variables, closely related to 3+1 decomposition relativity. At leading order expansion, these variables yield geometry and resulting des...

We characterise Lie groups with bi-invariant bargmannian, galilean or carrollian structures. Localising at the identity, we show that algebras ad-invariant structures are actually determined by same data: a metric algebra skew-symmetric derivation. This is data defining one-dimensional double extension of and, indeed, bargmannian coincide such extensions, containing as an ideal and projecting t...

Carroll symmetry is a very powerful characteristic of generic null surfaces, as it replaces the usual Poincar\'e algebra with vanishing speed light version thereof. These symmetries have found universal applications in physics manifolds they arise diverse situations ranging from black hole horizons to condensed matter systems Fermi velocities. In this work, we concentrate on fermions living two...

Purpose – The purpose of this paper is to investigate the perceptions of the roles, responsibilities and basic characteristics of audit committees (ACs) in the current business environment in China, from the perspectives of investors/creditors, independent directors (AC members), company officers and auditors. Design/methodology/approach – The study is conducted through a questionnaire survey o...

This investigation consisted of a job analysis of 6 National Collegiate Athletic Association Division I-A strength and conditioning coaches (SCC). All the subjects in the study were primarily responsible for providing strength and conditioning services to their institution's football programs. The procedures used for the gathering of data consisted of 3 questionnaires and a semi-structured inte...

BACKGROUND Gender roles influence men's attitudes towards reproductive health, and society might assume that reproductive health issues, fertility and family planning are women's responsibilities. Moreover, literature shows that men have insufficient knowledge about reproductive health matters and some misconceptions about modern contraceptive practices. OBJECTIVES The aim of the study was to...
