Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Moving-Object Tracking Algorithm Based on PCA-SIFT and Optimization for Underground Coal Mines
In view of the complex and changeable environment in underground coal mines, an improved algorithm based on the principal component analysis-scale invariant feature transform (PCA-SIFT) and mean shift is proposed to address the issues for which existing ...

Amenable Groups and Invariant Means
The problem of nonuniqueness of invariant finitely additive probability measures on \(S^ n\) is naturally linked to amenability properties. The general question was raised by J. Rosenblatt. Whereas by set theoretical arguments nonuniqueness was established for nilpotent and solvable groups, the author makes use of analytical methods to prove that for ...

On the range of an invariant mean [PDF]
Introduction. Let S be a discrete semigroup, m(S) the space of bounded real functions on S with the usual sup. norm, and m(S)* the conjugate Banach space of m(S). An element b e m(S)* is a mean if O(f) >0 whenever f>0 and #(1) =1, where 1 denotes also the constant one function on S.

Left mean-ergodicity, fixed points, and invariant means
Recently Lau [15] generalized a result of Yeadon [25]. In the present paper we generalize Yeadon's result in another direction recasting it as a theorem of ergodic type.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Majorisation ordering of measures invariant under transformations of the interval
PhDMajorisation is a partial ordering that can be applied to the set of probability measures on the unit interval I = [0, 1). Its defining property is that one measure μ majorises another measure , written μ , if R I fdμ R I fd for every ...
