Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Distribution of Eigenvalues in Multivariate Statistical Analysis
The Annals of Statistics, 1983 Ten invariant multivariate testing problems involving the real, complex, or quaternion structure of covariance matrices are considered. In each problem the maximal invariant statistic and its distribution are described, as well as the maximum likelihood estimators and likelihood ratio test statistics.

Layer‐Dependent Antiferromagnetic Chern and Axion Insulating States in UOTe
Advanced Science, EarlyView.Layer‐dependent topological phases are identified in the van der Waals antiferromagnet UOTe. Ab initio calculations reveal bilayer UOTe as a rare example of high‐temperature antiferromagnetic Chern insulator with quantized Hall conductivity and near‐zero net magnetization, while odd‐layer films exhibit axion‐insulator‐like behavior with quantized spin ...

First eigenvalues of geometric operators under the Yamabe flow
, 2018 Suppose $(M,g_0)$ is a compact Riemannian manifold without boundary of dimension $n\geq 3$. Using the Yamabe flow, we obtain estimate for the first nonzero eigenvalue of the Laplacian of $g_0$ with negative scalar curvature in terms of the Yamabe metric ...

Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices
Advanced Science, EarlyView.This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

Semiconducting THO‐C3N Monolayers for Ultrahigh Anisotropic Carrier Mobility
Advanced Science, EarlyView.A precise site‐specific N‐doping strategy that drives a secondary electronic transition in net W is proposed, enabling the electronic properties transition from metal to Dirac semimetal and ultimately to semiconductor. The obtained THO‐C3N‐2 and THO‐C3N‐3 semiconductors exhibit high carrier mobilities and pronounced mobility anisotropy, with THO‐C3N‐2 ...
