Cosmological bounds on large extra dimensions from non-thermal production of Kaluza-Klein modes

open access: yes, 2003
The existing cosmological constraints on theories with large extra dimensions rely on the thermal production of the Kaluza-Klein modes of gravitons and radions in the early Universe.

Some universal features of the effective string picture of pure gauge theories

open access: yes, 1992
The effective string describing the large distance behaviour of the quark sources of gauge field theories in the confining phase in D=3 or D=4 space-time dimensions can be formulated, in the infrared limit, as a suitable 2D conformal field theory on ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Light scalars on cosmological backgrounds

open access: yesJournal of High Energy Physics, 2018
We study the behaviour of a light quartically self-interacting scalar field ϕ on curved backgrounds that may be described with the cosmological equation state parameter w.

Breaking down the laughter: an exploration into the linguistic dimensions in stand-up comedy ratings

open access: yesBMC Psychology
Despite the pervasive influence of humor in society, comprehensive quantitative studies exploring its dimensions and societal reception are scarce. This study advances the field by analyzing stand-up comedy specials, linking linguistic elements to humor ...

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

open access: yesFEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Liouville theory: an introduction to rigorous approaches

open access: yesJournal of High Energy Physics
In recent years, a surprisingly direct and simple rigorous understanding of quantum Liouville theory has developed. We aim here to make this material more accessible to physicists working on quantum field theory.

Nonperturbative bounds on scattering of massive scalar particles in d ≥ 2

open access: yesJournal of High Energy Physics, 2022
We study two-to-two scattering amplitudes of a scalar particle of mass m. For simplicity, we assume the presence of ℤ2 symmetry and that the particle is ℤ2 odd.
