Time-dependent quantum scattering in 2+1 dimensional gravity

, 1995
The propagation of a localized wave packet in the conical space-time created by a pointlike massive source in 2+1 dimensional gravity is analyzed. The scattering amplitude is determined and shown to be finite along the classical scattering directions due

Asymptotically Scattered Spaces

, 2012
We define thin and asymptotically scattered metric spaces as asymptotic counterparts of discrete and scattered metric spaces respectively. We characterize asymptotically scattered spaces in terms of prohibited subspaces, and classify thin metric spaces up to coarse equivalence. We introduce the types of asymptotically scattered spaces and construct the

Scattered spaces and selections

Topology and its Applications, 2017
Let \(\mathcal{F}(X)\) be the space that consists of all non-empty, closed subsets of \(X\) endowed with the Vietoris topology. The author starts with a brief discussion of continuous zero-selections. After that it is proven that a crowded space \(X\) with a continuous selection for \(\mathcal{F}(X)\) always contains a copy of the rational numbers ...

Predicting Epileptogenic Tubers in Patients With Tuberous Sclerosis Complex Using a Fusion Model Integrating Lesion Network Mapping and Machine Learning

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate localization of epileptogenic tubers (ETs) in patients with tuberous sclerosis complex (TSC) is essential but challenging, as these tubers lack distinct pathological or genetic markers to differentiate them from other cortical tubers.

A Relativistic Formula for the Multiple Scattering of Photons

The Astrophysical Journal Letters
We have discovered analytical expressions for the probability density function (PDF) of photons that are multiply scattered in relativistic flows, under the assumption of isotropic and inelastic scattering.

Deep tissue space-gated microscopy via acousto-optic interaction

Nature Communications, 2020
In ideal diffraction-limited optical microscopy imaging depth is limited by the multiply scattered wave. Here, the authors present a space gating method, based on an acoustic focus in the object plane and reconstruction using only the acousto-optically ...

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Charge superradiance on charged BTZ black holes

European Physical Journal C: Particles and Fields
We study superradiant scattering for a charged scalar field subject to Robin (mixed) boundary conditions on a charged BTZ black hole background. Scalar field modes having a real frequency do not exhibit superradiant scattering, independent of the ...

The scattering of small bodies in planetary systems: constraints on the possible orbits of cometary material

, 2011
The scattering of small bodies by planets is an important dynamical process in planetary systems. We present an analytical model to describe this process using the simplifying assumption that each particle's dynamics is dominated by a single planet at a ...

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.
