Undulating compression and multistage relaxation in a granular column consisting of dust particles or glass beads

open access: yesPhysical Review Research, 2021
For fundamentally characterizing the effect of hierarchical structure in granular matter, a set of compression-relaxation tests for dust particles and glass beads confined in a cylindrical cell was performed.

The Physics of ALICE HLT Trigger Modes [PDF]

open access: yes, 2002
We discuss different physics cases, mainly of the ALICE TPC, such as pile-up, jets in pp and PbPb, Bottonium and Charmonium spectroscopy, and there corresponding demands on the ALICE High Level Trigger (HLT) System.

On compressive radial tidal forces

open access: yes, 2007
Radial tidal forces can be compressive instead of disruptive, a possibility that is frequently overlooked in high level physics courses. For example, radial tidal compression can emerge in extended stellar systems containing a smaller stellar cluster ...

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

A New Fourth Order Compression Dependent Equation of State

open access: yesEast European Journal of Physics
This study introduces a new first- to fourth-order exponential equation of state (EOS) to enhance accuracy across varying compression levels. The proposed exponential EOS is compared to the widely used fourth-order Birch-Murnaghan EOS, and it not only ...

Physics-based and data-driven modeling for stability evaluation of buried structures in natural clays

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
This study presents a hybrid framework to predict stability solutions of buried structures under active trapdoor conditions in natural clays with anisotropy and heterogeneity by combining physics-based and data-driven modeling.

A constrained random-force model for weakly bending semiflexible polymers

open access: yes, 2011
The random-force (Larkin) model of a directed elastic string subject to quenched random forces in the transverse directions has been a paradigm in the statistical physics of disordered systems. In this brief note, we investigate a modified version of the

Compressible flow with vacuum and physical singularity [PDF]

open access: yesMethods and Applications of Analysis, 2000
The first part is devoted to the study of Euler equations in one space dimension, in the compressible, isentropic, vacuum case with damping. The vacuum boundary is said to be physical if in a small neighborhood of the boundary \(0

A Review of the Melting Curves of Transition Metals at High Pressures Using Static Compression Techniques

open access: yesCrystals, 2021
The accurate determination of melting curves for transition metals is an intense topic within high pressure research, both because of the technical challenges included as well as the controversial data obtained from various experiments.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...
