A splitting criterion for vector bundles on blowing ups of the plane
, 2008 Let $f_s: X_s \to {\bf {P}}^2$ be the blowing-up of $s$ distinct points and $E$ a vector bundle on $X_s$. Here we give a cohomological criterio which is equivalent to $E \cong f_s^\ast (A)$ with $A$ a direct sum of line bundles. We also some cohomological characterizations of very particular rank 2 vector bundles on ${\bf {P}}^2$.

Advanced Science, EarlyView.MeO‐2PACz‐functionalized MXene nanosheets create a thermally conductive buried interface in inverted perovskite solar cells. The interface improves heat spreading, suppresses defects and ion migration, and strengthens charge extraction, extending T80 at 65°C from 141 to 687 h while maintaining competitive efficiency.

Electronic Journal of Differential Equations, 2012 In this article, we study the blow-up of strong solutions to the magneto-micropolar (MMP) fluid equations in $mathbb{R}^3$. It is proved that if the gradient field of velocity satisfies $$ abla uin L^{2/(2-r)}(0,T;dot{X}_r(mathbb{R}^3))quad hbox ...

A blow-up criterion for the compressible liquid crystals system
, 2010 In this paper, we establish a blow-up criterion for the compressible liquid crystals equations in terms of the gradient of the velocity only, similar to the Beale-Kato-Majda criterion \cite{majda} for ideal incompressible flows and the criterion obtained by Huang and Xin \cite{xin2} for the compressible Navier-Stokes equations.

Advanced Science, EarlyView.Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.
