Advanced Functional Materials, EarlyView.InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...

Laws of the iterated logarithm for iterated perturbed random walks
Modern Stochastics: Theory and ApplicationsLet ${({\xi _{k}},{\eta _{k}})_{k\ge 1}}$ be independent identically distributed random vectors with arbitrarily dependent positive components and ${T_{k}}:={\xi _{1}}+\cdots +{\xi _{k-1}}+{\eta _{k}}$ for $k\in \mathbb{N}$. The random sequence ${({T_{k}}

Phenomenological picture of fluctuations in branching random walks
, 2014 We propose a picture of the fluctuations in branching random walks, which leads to predictions for the distribution of a random variable that characterizes the position of the bulk of the particles.

New Insights into the Multifractal Formalism of Branching Random Walks on Galton–Watson Tree
MathematicsIn the present work, we consider three branching random walk SnZ(t),Z∈{X,Y,Φ} on a supercritical random Galton–Watson tree ∂T. We compute the Hausdorff and packing dimensions of the level set Eχ(α,β)=t∈∂T:limn→∞SnX(t)SnY(t)=αandlimn→∞SnY(t)n=β, where ∂T ...

Fluid Forces Control Structural Remodeling of Blind‐Ended Lymphatic Microvessels
Advanced Healthcare Materials, EarlyView.Using innovative microfluidic biofabrication with fluid mechanical insights, we recapitulated the blind‐ended microanatomy and physiological drainage properties of capillary lymphatics. Our results reveal the interrelationship between intra‐ and extraluminal regions of lymphatic vessels due to flow‐induced sprouting and morphological changes that ...

Branching random walk in random environment on trees
Stochastic Processes and their Applications, 2003 The authors consider a supercritical branching random walk on a rooted tree with random environment, the special attention being paid to the case where both the branching and the step transition parameters are random quantities. For this model criteria of recurrence (strong recurrence) and transience (strong transience) are presented.

Branching structure within random walk [PDF]
SCIENTIA SINICA Mathematica, 2019 Random walk is one of the most classical stochastic processes. It has been extensively studied by using analysis methods such as the probability generating function, and there are abundant research results about it. The intrinsic branching structure within the (nearest-neighborhood) random walk, which can be obtained by decomposing the path of the walk,
