Compactness of the Complex Green Operator on C1 Pseudoconvex Boundaries in Stein Manifolds
MathematicsWe study compactness for the complex Green operator Gq associated with the Kohn Laplacian □b on boundaries of pseudoconvex domains in Stein manifolds. Let Ω⋐X be a bounded pseudoconvex domain in a Stein manifold X of complex dimension n with C1 boundary.

Local Squeezing Casting Influence on the Compactness of AlSi10Mg Alloy Castings [PDF]
Metalurgija, 2007 The aim of the local squeezing casting process examination has been to eliminate the hot spot i.e. the place of potential formation of shrinkage porosity. The influence of variation of process parameters on the density i.e.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Dual Toeplitz Operators on Bounded Symmetric Domains
MathematicsWe give some characterizations of dual Toeplitz operators acting on the orthogonal complement of the Bergman space over bounded symmetric domains. Our main result characterizes those finite sums of products of Toeplitz operators that are themselves dual ...

Compact and weakly compact multiplications on C^∗-algebras
Annales Academiae Scientiarum Fennicae Series A I Mathematica, 1989 As proved by \textit{K. Vala} in [Ann. Acad. Sci. Fenn. Ser. A I 351, 9 p. (1964; Zbl 0132.098)], the linear operator \(X\mapsto SXT\), with \(S, T, X\) bounded operators on some Hilbert space \(H\), is compact on \(B(H)\) if and only if both S and T are compact operators (provided \(S\neq 0\) and \(T\neq 0)\).

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Impact of urban spatial compactness on air pollution in China
Frontiers in Environmental ScienceAs China’s urbanization advances, it is necessary to explore the path of reducing air pollution from the perspective of urban spatial compactness. We established a dataset containing Landcover data, PM2.5 surface annual average concentration data, urban ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

MathematicsIn this paper, we establish sufficient conditions for the pre-compactness of sets in the global Morrey-type spaces GMpθw(·). Our main result is the compactness of the commutators of the Riesz potential b,Iα in global Morrey-type spaces from GMp1θ1w1 ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.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.
