Bubble-wall velocity in local thermal equilibrium: hydrodynamical simulations vs analytical treatment

Journal of High Energy Physics
We perform real-time hydrodynamical simulations of the growth of bubbles formed during cosmological first-order phase transitions under the assumption of local thermal equilibrium.

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

FEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

Exploring the Quantum Universe: Pathways to Innovation and Discovery in Particle Physics [PDF]

, 2023
Particle physics studies the smallest constituents of our vast and complex universe. At such small scales, the fundamental principles of quantum physics prevail.

Non-linearities in cosmological bubble wall dynamics

Journal of High Energy Physics
A precise modelling of the dynamics of bubbles nucleated during first-order phase transitions in the early Universe is pivotal for a quantitative determination of various cosmic relics, including the stochastic background of gravitational waves.

Bubble nucleation and quantum initial conditions in classical statistical simulations

Journal of High Energy Physics, 2022
Classical-statistical lattice simulations provide a useful approximation to out-of-equilibrium quantum field theory, but only for systems exhibiting large occupation numbers, and only for phenomena that are not intrinsically quantum mechanical in nature.

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

Molecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Topics in Theoretical Particle Physics and Cosmology beyond the Standard Model [PDF]

, 2006
We review our understanding of spin-1 and spin-2 massless particles as mediators of long-range forces. We discuss how a quantum description of such particles that is compatible with Lorentz covariance leads to gauge invariance, a mathematical redundancy

Bubble friction in symmetry-restoring transitions

Journal of High Energy Physics
In standard (symmetry-breaking) first-order phase transitions, the frictional pressure on expanding bubble walls can be dominated by transition radiation — the emission of a gauge boson with phase-dependent masses as particles present in the thermal ...

USP7 inhibits FOXO1 activity in chronic lymphocytic leukaemia cells enhancing cell survival

Molecular Oncology, EarlyView.
CLL cells rely on BCR‐mediated signalling for survival and proliferation in part through suppression of FOXO1. FOXO1 activity is regulated by a plethora of post‐translational modifications including phosphorylation and ubiquitination. We demonstrated that dual inhibition of BCR signalling and the deubiquitinase USP7 activates FOXO1, modulating its ...

From friction scaling to an efficient method for estimating bubble wall velocity

Journal of High Energy Physics
We present a unified description of first-order cosmological phase transition dynamics that links the phenomenological friction model employed in hydrodynamic simulations to the microscopic treatment based on Boltzmann equations. We derive an approximate
