AKG‐VO: Adaptive Keyframe Generation Method for Improving Visual Odometry in Autonomous Vehicles
Advanced Intelligent Systems, EarlyView.An adaptive keyframe generation method for pose estimation is proposed, incorporating optical flow‐based interframe gap estimation and video frame interpolation techniques. By limiting interframe gaps, meaningful keyframes are generated to enhance tracking reliability.

Next Generation Modeling of Glioblastoma Progression: Diffusing Through Time and Brain
Annalen der Physik, EarlyView.Glioblastoma (GBM) is a fatal brain tumor that will inevitably recur following surgical resection. Early mathematical tumor growth models used the reaction‐diffusion equation to describe the proliferation and invasion of tumor spread. However, with increasingly advanced neuroimaging technology, diffusion tensor imaging data has more recently been ...

Critical System Size for the Recovery of Topological Zero Modes in Finite Non‐Hermitian Systems
Annalen der Physik, EarlyView.A generalized non‐Hermitian SSH model on a topolectrical circuit reveals size‐dependent topological zero modes. Non‐Hermiticity enables exact zero‐admittance edge states at a critical system size, tunable via asymmetric coupling and gain/loss. Large impedance peaks signal these modes, offering insights for designing robust topological devices with ...

ChemistryEurope, EarlyView.Reacting 1‐hydridosilatrane with triphenylcarbenium hexachloridoantimonate in acetonitrile solution and in the presence of 4‐dimethylaminopyridine combines the world of silatranes with the world of carbenes, giving an unprecedented carbene‐type antimony pentachloride complex. This finding offers a new playground for exciting new chemistry.

The Feynman-Kitaev computer's clock: bias, gaps, idling and pulse tuning
, 2018 We present a collection of results about the clock in Feynman's computer construction and Kitaev's Local Hamiltonian problem. First, by analyzing the spectra of quantum walks on a line with varying endpoint terms, we find a better lower bound on the gap ...

Chemistry–Methods, EarlyView.Expanded porphyrins, with their flexible structures and rich redox chemistry, offer a powerful platform to explore how aromaticity shapes molecular properties. This review introduces a multidimensional framework to quantify Hückel and Möbius aromaticity and examines its impact on the spectroscopic behavior across redox‐ and topology‐controlled expanded

Sharp commutator estimates of all order for Coulomb and Riesz modulated energies
Communications on Pure and Applied Mathematics, EarlyView.Abstract We prove functional inequalities in any dimension controlling the iterated derivatives along a transport of the Coulomb or super‐Coulomb Riesz modulated energy in terms of the modulated energy itself. This modulated energy was introduced by the second author and collaborators in the study of mean‐field limits and statistical mechanics of ...

Isospectral deformations of the Dirac operator [PDF]
, 2013 We give more details about an integrable system in which the Dirac operator D=d+d^* on a finite simple graph G or Riemannian manifold M is deformed using a Hamiltonian system D'=[B,h(D)] with B=d-d^* + i b. The deformed operator D(t) = d(t) + b(t) + d(t)^
