Advanced Functional Materials, EarlyView.Herein, an RBC membrane‐derived nanoparticle (CMN‐ICG) is engineered to efficiently deliver a sonosensitizing agent, indocyanine green (ICG), for sonotherapy of hepatocellular carcinoma (HCC). CMN‐ICG exhibits excellent cytocompatibility, significantly enhances hepatocyte uptake, and produces excessive reactive oxygen species (ROS) upon ultrasound ...

Dynamic Limits on Planar Libration-Orbit Coupling Around an Oblate Primary
, 2012 This paper explores the dynamic properties of the planar system of an ellipsoidal satellite in an equatorial orbit about an oblate primary. In particular, we investigate the conditions for which the satellite is bound in librational motion or when the ...

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Advanced Functional Materials, EarlyView.Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Gravitational Lenses With More Than Four Images: I. Classification of Caustics
, 2000 We study the problem of gravitational lensing by an isothermal elliptical density galaxy in the presence of a tidal perturbation. When the perturbation is fairly strong and oriented near the galaxy's minor axis, the lens can produce image configurations ...

Advanced Functional Materials, EarlyView.Applying a high electric field to a doped organic semiconductor heats up the charge carrier distribution beyond the lattice temperature, enhancing conductivity. It is shown that the associated effective temperature can be used to extract the effective localization length, which is a characteristic length scale of charge transport and provides ...

Improved Bounds and Containing Ellipsoids in Karmarkar's Linear Programming Algorithm [PDF]
Mathematics of Operations Research, 1988 Karmarkar's projective algorithm for linear programming provides not only primal solutions but dual solutions giving bounds on the optimal value. Here we show how improved bounds can be obtained at the expense of solving a two-dimensional linear programming problem at every iteration, and also how an ellipsoid containing all dual optimal solutions can

Extended Ellipsoidal Outer‐Bounding Set‐Membership Estimation for Nonlinear Discrete‐Time Systems with Unknown‐but‐Bounded Disturbances [PDF]
Discrete Dynamics in Nature and Society, 2016 This paper develops an extended ellipsoidal outer‐bounding set‐membership estimation (EEOB‐SME) algorithm with high accuracy and efficiency for nonlinear discrete‐time systems under unknown‐but‐bounded (UBB) disturbances. The EEOB‐SME linearizes the first‐order terms about the current state estimations and bounds the linearization errors by ellipsoids ...

Advanced Functional Materials, EarlyView.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

A Comparison of Stealthy Sensor Attacks on Control Systems
, 2017 As more attention is paid to security in the context of control systems and as attacks occur to real control systems throughout the world, it has become clear that some of the most nefarious attacks are those that evade detection.

Lower and upper bounds for chord power integrals of ellipsoids [PDF]
Applied Mathematical Sciences, 2014 First we discuss dierent representations of chord power integrals Ip(K) of any order p 0 for convex bodies K R d with inner points. Second we derive closed-term expressions of Ip(E(a)) for an ellipsoid E(a) with semi-axes a = (a1;:::;ad) in terms of the support function of E(a) and prove upper and lower bounds expressed by the volume and the mean ...
