Against the background of a variety polarized optical applications, great number polarization-sensitive photodetectors based on anisotropic two-dimensional (2D) materials and their heterojunctions have been proposed. However, low polarization ratio (PR), describing response sensitivity angle incident light, is still demanding to be solved. In this work, we demonstrate van der Waals (vdW) Schott...

We present a branching ratio measurement for the beta decay of neutral Cascade hyperon, 0 ! + e e , using the KTeV detector at Fermilab. We used the principal decay mode of 0 ! 0 where ! p , as the ux normalization mode. The status of the measurement of the ratio of the axial-vector to vector coupling (g1/f1) for the Cascade beta decay will also be discussed. Furthermore, we present the prelimi...

A reanalysis of unpolarized electron-proton elastic scattering data is done in terms of the electric to magnetic form factor squared ratio. This observable is in principle more robust against experimental correlations and global normalizations. The present analysis shows indeed that it is a useful quantity that contains reliable and coherent information. The comparison with the ratio extracted ...

Programmed cell death (apoptosis) is primarily mediated by Fas ligand (FasL; CD95L) and the Fas receptor (Fas; CD95). In this study, FasL was detected by immunohistochemical analysis in 85% of breast carcinomas and 14% of fibroadenomas randomly chosen, indicating that high expression of FasL might play a role in tumor pathology. FasL and Fas levels as well as FasL:Fas ratios were further ascert...

The Bayes factor is commonly used for assessing the evidence for or against a given hypothesis H0 : θ ∈ Θ0, where Θ0 is a subset of the parameter space. In this paper we discuss the Bayes factor and various issues associated with its use. A Bayes factor is seen to be intimately connected with a relative belief ratio which provides a somewhat simpler approach to assessing the evidence in favor o...

Disequilibrium between bone-forming osteoblasts and bone-resorbing osteoclasts is central to many bone diseases. Here, we show that dysregulated expression of translationally controlled isoforms of CCAAT/enhancer-binding protein beta (C/EBPbeta) differentially affect bone mass. Alternative translation initiation that is controlled by the mammalian target of rapamycin (mTOR) pathway generates lo...
