Potential Barrier Classification by Short-Time Measurement

, 2006
We investigate the short-time dynamics of a delta-function potential barrier on an initially confined wave-packet. There are mainly two conclusions: A) At short times the probability density of the first particles that passed through the barrier is ...

Celiac Disease Monocytes Induce a Barrier Defect in Intestinal Epithelial Cells [PDF]

, 2019
Intestinal epithelial barrier function in celiac disease (CeD) patients is altered. However, the mechanism underlying this effect is not fully understood.

Claudin-1 decrease impacts epidermal barrier function in atopic dermatitis lesions dose-dependently

Scientific Reports, 2020
The transmembrane protein claudin-1 is a major component of epidermal tight junctions (TJs), which create a dynamic paracellular barrier in the epidermis. Claudin-1 downregulation has been linked to atopic dermatitis (AD) pathogenesis but variable levels

Hierarchical Contrastive Representation for Accurate Evaluation of Rehabilitation Exercises via Multi-View Skeletal Representations

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Rehabilitation training is essential for the recovery of patients with conditions such as stroke and Parkinson’s disease. However, traditional skeletal-based assessments often fail to capture the subtle movement qualities necessary for ...

The influence of Akkermansia muciniphila on intestinal barrier function

Gut Pathogens
Intestinal barriers play a crucial role in human physiology, both in homeostatic and pathological conditions. Disruption of the intestinal barrier is a significant factor in the pathogenesis of gastrointestinal inflammatory diseases, such as inflammatory

Random barrier double-well model for resistive switching in tunnel barriers [PDF]

, 2011
The resistive switching phenomenon in MgO-based tunnel junctions is attributed to the effect of charged defects inside the barrier. The presence of electron traps in the MgO barrier, that can be filled and emptied, locally modifies the conductance of the

Hypoxia-enhanced Blood-Brain Barrier Chip recapitulates human barrier function and shuttling of drugs and antibodies

Nature Communications, 2019
The high selectivity of the human blood-brain barrier (BBB) restricts delivery of many pharmaceuticals and therapeutic antibodies to the central nervous system.

Commensal Microbiota Regulates Skin Barrier Function And Repair Via Signaling Through The Aryl Hydrocarbon Receptor

bioRxiv, 2020
The epidermis forms a barrier that defends the body from desiccation and entry of harmful substances, while sensing and integrating environmental signals. The tightly orchestrated cellular changes required for the proper formation and maintenance of this

Cooperative evolution with reward-based heterogeneous tax in spatial public goods games

iScience
Summary: In recent years, incorporating tax mechanisms into evolutionary game theory has become a popular research focus. However, previous studies often failed to simultaneously consider the coexistence of heterogeneity in tax collection and ...
