Multi‐Scaled Cellulosic Nanonetworks from Tunicates
Advanced Functional Materials, EarlyView.Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Low-dimensional lonely branching random walks die out [PDF]
arXiv, 2017 The lonely branching random walks on ${\mathbb Z}^d$ is an interacting particle system where each particle moves as an independent random walk and undergoes critical binary branching when it is alone. We show that if the symmetrized walk is recurrent, lonely branching random walks die out locally.

Precise upper deviation estimates for the maximum of a branching random walk [PDF]
Electron. J. Probab. 30: 1-30 (2025)We consider the precise upper large deviations estimates for the maximal displacement of a branching random walk. In addition, we obtain a description of the extremal process of the branching random walk conditioned on this large deviations event. This introduces a family of point measure playing a role similar to the decoration measures introduced in [

Branching random walk in random environment on trees
Stochastic Processes and their Applications, 2003 AbstractWe study a supercritical branching random walk on a rooted tree with random environment. We are interested in the case where both the branching and the step transition parameters are random quantities. Criteria of (strong) recurrence and (strong) transience are presented for this model.

Coalescing-Branching Random Walks on Graphs [PDF]
ACM Transactions on Parallel Computing, 2013 We study a distributed randomized information propagation mechanism in networks we call the coalescing-branching random walk (cobra walk, for short). A cobra walk is a generalization of the well-studied “standard” random walk, and is useful in modeling and understanding the Susceptible-Infected- Susceptible (SIS ...

Advanced Functional Materials, EarlyView.Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).

Spreading speeds in reducible multitype branching random walk
, 2012 This paper gives conditions for the rightmost particle in the $n$th generation of a multitype branching random walk to have a speed, in the sense that its location divided by n converges to a constant as n goes to infinity. Furthermore, a formula for the

On the critical branching random walk II: Branching capacity and branching recurrence [PDF]
arXiv, 2016 We continue our study of critical branching random walk and branching capacity. In this paper we introduce branching recurrence and branching transience and prove an analogous version of Wiener's Test.

Oxidized Carbon Nanoparticles Enhance Cellular Energetics With Application to Injured Brain
Advanced Healthcare Materials, Volume 14, Issue 8, March 25, 2025.Oxidized carbon nanozymes (OCNs) that catalyze the dismutation of superoxide radical and oxidation of reduced nicotinamide adenine dinucleotide (NADH) to NAD+ promote glycolytic and mitochondrial energy metabolism under impaired conditions observed in traumatic brain injury with hemorrhage.
