Poincaré-Type Inequalities for the Composite Operator in L𝒜-Averaging Domains

Abstract and Applied Analysis, 2014
We first establish the local Poincaré inequality with L𝒜-averaging domains for the composition of the sharp maximal operator and potential operator, applied to the nonhomogenous A-harmonic equation.

Entropic formulation of the uncertainty principle for the number and annihilation operators

, 2011
An entropic approach to formulating uncertainty relations for the number-annihilation pair is considered. We construct some normal operator that traces the annihilation operator as well as commuting quadratures with a complete system of common ...

CONVERSES OF JENSEN'S OPERATOR INEQUALITY

, 2010
We give a generalization of converses of Jensen's operator inequality for fields of positive linear mappings $(\phi_t)_{; ; t \in T}; ; $ such that $\int_T \phi_t(1) d\mu(t) = k 1$ for some positive scalar k.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Flipping the Switch: MeCP2‐Mediated Lactylation Rewires Microglial Metabolism and Inflammation via the HK2/mTOR Axis in Poststroke Neuroinflammation

Advanced Science, EarlyView.
Stroke‐induced lactate accumulation promotes p300‐mediated lactylation of methyl‐CpG binding protein 2 (MeCP2) at lysine 210, which reprograms microglial metabolism toward glycolysis and activates the hexokinase 2 (HK2)/mTOR axis. This cascade promotes proinflammatory responses and impairs neurofunctional outcomes.

Variational-Like Inequality Problem Involving Generalized Cayley Operator

Axioms, 2021
This article deals with the study of a variational-like inequality problem which involves the generalized Cayley operator. We compare our problem with a fixed point equation, and based on it we construct an iterative algorithm to obtain the solution of ...

Spectral inequality and resolvent estimate for the bi-Laplace operator [PDF]

Journal of the European Mathematical Society (Print), 2015
On a compact Riemannian manifold with boundary, we prove a spectral inequality for the bi-Laplace operator in the case of so-called "clamped" boundary conditions , that is, homogeneous Dirichlet and Neumann conditions simultaneously.

Single‐Target Pairing System (StarPair) for Large‐Scale Interrogation of Cell–Cell Interactions

Advanced Science, EarlyView.
This work presents a single‐target pairing system, StarPair, enabling cell–cell interaction studies by target combination in droplets. StarPair offers superior pairing efficiencies over 95% and operation frequencies of 105 pairs per 9.5 h for two‐target pairing, allowing large‐scale interrogation of immune cell‐cancer cell interactions and precise ...

Generalized Gram–Hadamard inequality [PDF]

, 2010
We generalize the classical Gram determinant inequality. Our generalization follows from the boundedness of the antisymmetric tensor product operator.

Geometric operator inequalities

Linear Algebra and its Applications, 1997
In a given \(C^*\)-algebra there are several interesting subsets (e.g., the set of idempotent elements, the set of selfadjoint invertible elements, the set of nilpotent elements of a given order, the similarity and unitary orbits of elements etc.) that have a differentiable structure and in which the length of curves is measured by means of a Finsler ...
