Advanced Science, EarlyView.Safe and precise bioorthogonal therapy of tumors was achieved by an ultrasound‐responsive heterostructured nanoreactor with on‐demand catalytic activity. Under piezoelectric catalysis, the system undergoes reversible Pd2+/Pd0 redox cycling, concurrently enabling spatiotemporally controlled prodrug activation and self‐terminating catalytic dose ...

A geometric proof of a theorem on antiregularity of generalized quadrangles [PDF]
, 2012 A geometric proof is given in terms of Laguerre geometry of the theorem of Bagchi, Brouwer and Wilbrink, which states that if a generalized quadrangle of order s > 1 has an antiregular point then all of its points are antiregular.

Phase‐Dependent Oxygen Defect Energetics in Epitaxial NbN/AlN/NbN Films
Advanced Science, EarlyView.Phase dependent oxygen defect energetics in epitaxial δ‐NbN/AlN/δ‐NbN and β‐Nb2N/AlN/β‐Nb2N trilayers. Atomic‐scale analysis and first‐principles calculations reveal distinct oxygen incorporation pathways across NbN polymorphs. Layer resolved defect formation energies show that O is energetically more favorable within δ‐NbN electrodes, whereas in β ...

Monomial graphs and generalized quadrangles
Finite Fields and Their Applications, 2012 In this paper, the author proves the nonexistence of certain generalized quadrangles of order \((s,s)\), with \(s\) an odd prime power. This is achieved by considering the graph of points and lines far away from a flag of such a quadrangle, identifying the point and line sets with 3-dimensional vector space over \(\mathrm{GF}(s)\), coordinatizing, and ...

Generalized Quadrangles and the Higman-Sims Technique
European Journal of Combinatorics, 1981 Let S be a generalized quadrangle of order (s, t). Let O = {x1, ..., xq} be a set of points of S, q ≥ 2, and put b1 equal to the number of points (≠x1) of O that are collinear with xi,b¯=∑bi/q. Suppose Δ = Δ1+ ⋯ + Δf is a partition of some set Δ of tangent lines to O satisfying the following: f ≥ 2; for 1, i ≤ i ≤ f, each point of O is on θ lines in Δi;

Neuromorphic Devices and Computing for Sensing, Memory, and Control
Advanced Science, EarlyView.This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Advanced Science, EarlyView.Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.

Topology in generalized quadrangles
Topology and its Applications, 1990 The study of topological generalized quadrangles, in particular 3- dimensional generalized quadrangles, was first taken up by \textit{M. Forst} [Mitt. Math. Semin. Gießen 147, 65-129 (1981; Zbl 0478.51013)]. The authors resume this subject and lay the basis for the study of topological generalized quadrangles in general dimension.

Advanced Science, EarlyView.Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Design Rules for Quantitative Control of Intragrain Planar Defects in Halide Perovskites
Advanced Science, EarlyView.Dose‐budgeted electron microscopy reveals the design rules governing intragrain planar defects in halide perovskites: {112}t ferroelastic twins proliferate with increasing tetragonality and grain size, whereas {111}c twins and stacking faults emerge as the lattice approaches cubic symmetry.
