Radial-velocity measurements of subdwarf B stars [PDF]
, 2011 Subdwarf B (sdB) stars are hot, subluminous stars which are thought to be core-helium burning with thin hydrogen envelopes. The mechanism by which these stars lose their envelopes has been controversial, but it has been argued that binary star ...

Radial solutions of Lane-Emden-Fowler equations with Pucci's extremal operators
Bruno Pini Mathematical Analysis Seminar, 2019 We report on some recent results obtained for positive radial solutions of Lane-Emden-Fowler type equations with Pucci's operators as principal parts.

Radial functions and maximal estimates for radial solutions to the Schrodinger equation
Tsukuba Journal of Mathematics, 1998 The author establishes the following estimate for radial functions \(f\): If \(2\leq q\leq 8/3\), \(\alpha= q(2n-1)/4-n\), then \[ \Biggl(\int_{\mathbb{R}^n}| S^*f(x)|^q| x|^\alpha dx\Biggr)^{1/q}\leq C\| f\|_{H_{1/4}}, \] where the maximal functions \(S^*f\) is defined by \[ S^*f(x)= \sup_ ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

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 ...

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 ...

Blade row interaction in radial turbomachines [PDF]
, 1999 A computational study has been performed to investigate the effects of blade row interaction on the performance of radial turbomachines, which was motivated by the need to improve our understanding of the blade row interaction phenomena for further ...
