Advanced Science, EarlyView.As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Modular inequalities for the Calderón operator
Tohoku Mathematical Journal, 2000 The authors study increasing functions \(P,Q: [0,\infty )\rightarrow [0,\infty )\). Let \(S\) be the Calderón operator defined on positive decreasing functions, then they prove modular inequalities \(\int P(Sf)\leq C\int Q(f)\). The results are used to obtain weak type interpolation theorems for modular spaces.

Algebraic reflexivity of isometry groups and automorphism groups of some operator structures [PDF]
, 2013 We establish the algebraic re exivity of three isometry groups of operator structures: The group of all surjective isometries on the unitary group, the group of all surjective isometries on the set of all positive invertible operators equipped with ...

A Reconfigurable Memristive Spiking Neuron Enabling Advanced Neuromorphic Computing
Advanced Science, EarlyView.Pek Jun Tiw and co‐workers develop a reconfigurable memristive neuron that can exhibit four spiking behaviors with freely tunable spike train parameters. The neuron supports multiplexed spike encoding of multiple pieces of information. It also supports advanced neural network strategies, such as neural heterogeneity and dynamic mode switching ...

Linear Algebra and its Applications, 2000 \textit{F. Hansen} [Proc. Am. Math. Soc. 125, No. 7, 2093-2102 (1997; Zbl 0870.47013)] gave a characterization of operator convex functions in terms of Jensen's operator inequality. Following investigations by \textit{S. Friedland} and \textit{M. Katz} [Linear Algebra Appl. 85, 185-190 (1987; Zbl 0612.15010)], the author presents a simple proof of this

Antieigenvalue inequalities in operator theory [PDF]
International Journal of Mathematics and Mathematical Sciences, 2004 We will prove some inequalities among trigonometric quantities of two and three operators. In particular, we will establish an inequality among joint trigonometric quantities of two operators and trigonometric quantities of each operator. As a corollary, we will find an upper bound and a lower bound for the total joint antieigenvalue of two positive ...

Structural Divergence Between the Moltbook AI‐Agent Network and Human Social Networks
Advanced Science, EarlyView.Analysis of the Moltbook AI‐agent network reveals a striking combination of familiar global scaling and distinct internal organization. Attention is highly concentrated, reciprocity is limited, connected triads are suppressed, and communities are strongly modular.

Advanced Science, EarlyView.This study systematically assessed the global burden and temporal trends of EOTBL cancer in individuals aged 15–49 years. Smoking, ambient particulate matter pollution, and secondhand smoke remain dominant risk factors. Countries within the same Human Development Index (HDI) category exhibit distinct epidemiological trajectories, underscoring the need ...
