Abstract We investigated the effect of the electronic confinement potential on the electron–LO-phonon (el–LO-ph) interaction energy in a quantum well by using the variational method. In this work, the el–LO-ph interaction energy in the infinite (I) and finite (F) square potential quantum wells (SPQW) is calculated as a function of the well-width for all four different confined-optical-phonon (COP) models. The result shows that the el-LO-ph interaction energy in a quantum well is affected strongly by the electronic confinement potential for all four COP models. Except for the Ridley-Babiker mod

Fuchs found phenomena that when high voltage is applied to deionized water filled in two contacted beakers, a floating water bridge forms spontaneously. In this paper, we examined flow direction of water bridge and what effects the addition of electrolytes such as NaCl, NaOH, and to the floating water bridge would give. We found that ionization degree reduced the length of water bridge though insoluble electrolyte had no effect on the length of water bridge.

Abstract Nanometals, i.e., metals structured at the nanoscale, have gained increasing attention due to their excellent electronic applications. In the context of improving the electrical properties of nanometals, this study investigates the effect of phonon scattering, surface boundaries and grain boundaries on the electrical properties of magnesium (Mg) and palladium (Pd). An approximate equation is derived from the solution of the Boltzmann electron distribution equation by the Fuchs-Sondheimer and Mayadas-Shatzkes models, which takes into account the resistivity of the metal, as well as the

Abstract:

The thickness dependence of the Berreman effect for naturally grown oxide films on chrome is analyzed theoretically and experimentally. The shift of the spectral position of the Berreman minimum can be described by the Fuchs–Kliewer theory of virtual modes. Both the absorption and the shift of the position can be used for thickness determination. The experimental results compared with calculated values based on different optical constants for Cr2O3 indicate their influence on the position and the absorption of the Berreeman minimum.

The Monte Carlo method is used to study the effect of boundary scattering on the temperature dependent part of the resistivity of thin metal films. A computational scheme is used that realistically simulates electron scattering mechanisms in the semi-classical context. As a test of the accuracy of the method, comparison is made between the present method at absolute zero (impurity and boundary scattering only) and the analytical results of Fuchs, which rely on the relaxation time approximation (RTA).

Anomalous resistivity enhancement increases with decreasing both the periodicity and the modulated ratio, but is insensitive to the number of bilayers. Accounting for the effects of grain bounda

Fuchs endothelial corneal dystrophy (FECD) is a bilateral, hereditary syndrome characterized by progressive irreversible injury in the corneal endothelium; it is the most frequent cause for corneal transplantation worldwide.

The stimulation of the adenosine A2A receptor (A2Ar) inhibits oxidative stress, reduces inflammation and modulates apoptosis.

Abstract:

Fuchs’ endothelial corneal dystrophy (FECD) is a bilateral disease of the cornea caused by gradual loss of corneal endothelial cells. Late-onset FECD is strongly associated with the CTG18.1 trinucleotide repeat expansion in the Transcription Factor 4 gene (TCF4), which forms RNA nuclear foci in corneal endothelial cells. To date, 46 RefSeq transcripts of TCF4 are annotated by the National Center of Biotechnology information (NCBI), however the effect of the CTG18.1 expansion on expression of alternative TCF4 transcripts is not completely understood. To investigate this, we used droplet digital

Abstract:

During severe heat shock, which known to interrupt both splicing of RNA transcripts and nucleocytoplasmic transport, it is to be expected that the substructure of heterogeneous nuclear ribonucleoproteins (hnRNP) is altered in some way. Recently, we have shown that such a stress actually induces rapid alterations at the level of individual proteins (Lutz, Y., M. Jacob, and J.-P. Fuchs. 1988 Exp. Cell Res. 175:109-124). Here we report further investigations on two related 72.5-74-kD hnRNP proteins whose behavior is also rapidly modified by a heat shock at 45 degrees C, whereas no effect is obser

Abstract:

Mo(001) and Mo(011) layers with thickness d = 4–400 nm are sputter-deposited onto MgO(001) and α-Al2O3(112¯0) substrates and their resistivity is measured in situ and ex situ at room temperature and 77 K in order to quantify the resistivity size effect. Both Mo(001) and Mo(011) layers are epitaxial single crystals and exhibit a resistivity increase with decreasing d due to electron surface scattering that is well described by the classical Fuchs and Sondheimer model. Data fitting yields room temperature effective electron mean free paths λ*= 14.4 ± 0.3 and 11.7 ± 0.3 nm, respectively, indicati

Regulation of VWF multimer distribution is critical for its physiological function. In human plasma, VWF multimer gels reveal species of various multimeric sizes with flanking satellite bands (triplets). The faster and slower migrating bands encompassing a VWF multimer lack one N-terminal fragment or possess an additional N-terminal fragment, respectively. Defects in VWF secretion, impaired assembly of multimers, or increased proteolysis can cause von Willebran

Ceralasertib has demonstrated encouraging clinical benefits in patients with non-small cell lung cancer who were resistant to PD1/PDL1 treatment. Using different pre-clinical mouse tumor models, we found that antitumor effect of ceralasertib was dependent on CD8 T cells. In fact, depletion of CD8 cells abrogated therapeutic effect of the ATRi. Ceralasertib treatment caused pleotropic effect in TME. It improved the function of T cells, depleted tumor associated macrophage

Platinum-liquid electrolyte interfaces are one of the most studied in electrochemistry. Still, until very recently, knowledge of the interfacial changes during platinum oxidation and reduction remained elusive. This information is crucial for any electrochemical applications in which platinum is used as a catalyst as it allows its more economical utilization. For instance, if excursions to destructive higher anodic potentials are avoided in proton exchange membrane fuel cell (PEMFCs) cathodes, significantly lower platinum amounts can be used, still providing the required long-term operation.
