A universal deviation inequality for random polytopes [PDF]

open access: yesarXiv, 2013
We consider the convex hull of a finite sample of i.i.d. points uniformly distributed in a convex body in $\R^d$, $d\geq 2$. We prove an exponential deviation inequality, which leads to rate optimal upper bounds on all the moments of the missing volume of the convex hull, uniformly over all convex bodies of $\R^d$, with no restriction on their volume ...

High‐Fidelity Computational Microscopy via Feature‐Domain Phase Retrieval

open access: yesAdvanced Science, EarlyView.
An innovative phase retrieval framework, termed FD‐PR, is uniquely established in the image's feature domain through the feature‐extracted, physical‐driven regression with interfaces for combining physics and image processing constraints. FD‐PR takes advantage of invariance components of an image against presences of model mismatch and uncertainty ...

Cyclo‐N9−: a Novel 5/6 Fused Polynitrogen Anion for High Energy Density Materials

open access: yesAdvanced Science, EarlyView.
This study presents a novel 5/6 fused polynitrogen anion, cyclo‐N9−, which is assembled with four cations to form energetic salts. The computational results reveal that the energy densities and detonation performances of these systems are far superior, even surpassing those of CL‐20.

On strong asymptotic uniform smoothness and convexity [PDF]

open access: yesarXiv, 2017
We introduce the notions of strong asymptotic uniform smoothness and convexity. We show that the injective tensor product of strongly asymptotically uniformly smooth spaces is asymptotically uniformly smooth. This applies in particular to uniformly smooth spaces admitting a monotone FDD, extending a result by Dilworth, Kutzarova, Randrianarivony ...

Uncover Hidden Physical Information of Soft Matter by Observing Large Deformation

open access: yesAdvanced Science, EarlyView.
Detecting internal abnormalities in soft matter remains challenging due to its heterogeneous nature. This study introduces a method that infers hidden physical properties by matching observed deformation with simulation through parallel Bayesian optimization.

Neuroimaging for differential diagnosis of transient neurological attacks

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background Rapid yet comprehensive neuroimaging protocols are required for patients with suspected acute stroke. However, stroke mimics can account for approximately one in five clinically diagnosed acute ischemic strokes and the rate of thrombolyzed mimics can be as high as 17%.

Weak convergence theorem for Passty type asymptotically nonexpansive mappings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
In this paper, we prove a convergence theorem for Passty type asymptotically nonexpansive mappings in a uniformly convex Banach space with Fréchet-differentiable norm.

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids

open access: yesAdvanced Science, EarlyView.
This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for
