Brownian Web and Oriented Percolation: Density Bounds [PDF]

open access: yes, 2011
In a recent work, we proved that under diffusive scaling, the collection of rightmost infinite open paths in a supercritical oriented percolation configuration on the space-time lattice Z^2 converges in distribution to the Brownian web.

Design Optimization of a Variable Stiffness Robotic Gripper with Passive Restoration Fabricated by Multimaterial 3D Printing

open access: yesAdvanced Robotics Research, EarlyView.
A multimaterial robotic gripper fabricated via multimaterial 3D printing integrates conductive thermopolymer joints with flexible elastomeric components. Joule heating enables precise joint‐level stiffness modulation, enhanced by embedded temperature sensors, passive shape restoration, and active cooling, enabling versatile manipulation capabilities ...

A Novel Separation Technique of Flexural Loading-Induced Acoustic Emission Sources in Railway Prestressed Concrete Sleepers

open access: yesIEEE Access, 2019
This study determines the effectiveness and suitability of acoustic emission in order to monitor the structural health condition of railway pre-stressed concrete sleepers since the acoustic emission sensing provides effective means for detecting cracking

Extensions between Cohen-Macaulay modules of Grassmannian cluster categories

open access: yes, 2016
In this paper we study extensions between Cohen-Macaulay modules for algebras arising in the categorifications of Grassmannian cluster algebras. We prove that rank 1 modules are periodic, and we give explicit formulas for the computation of the period ...

Water‐Mediated 1,7‐Palladium Aryl‐to‐Aryl Migration in an Unusual Aryne Trimerization Enables the Synthesis of Multihelicenes with Profoundly Hindered Stereogenic Axes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

Archaeological Investigations at the Wade (GC-38) and Estes (GC-49) Sites in the Sabine River Basin, Gregg County, Texas [PDF]

open access: yes, 2014
Buddy C. Jones conducted extensive archaeological investigations in the 1950s and 1960s at many sites in the mid-Sabine River basin of East Texas, especially on Caddo sites of various ages in Gregg, Harrison, and Rusk counties. However, that work has not

Effective target arrangement in a deterministic scale-free graph

open access: yes, 2010
We study the random walk problem on a deterministic scale-free network, in the presence of a set of static, identical targets; due to the strong inhomogeneity of the underlying structure the mean first-passage time (MFPT), meant as a measure of transport

Obtaining Orthogonal Thermal Conductivity Components from Anisotropic Thin Films Using the Pseudo Steady‐State 3ω Method

open access: yesAdvanced Theory and Simulations, EarlyView.
Measurement of thin film thermal conductivity is challenging for isotropic materials, but is even more so for films with anisotropic in‐plane properties. This work establishes the pseudo steady‐state 3ω technique as a suitable method to extract orthogonal in‐plane thermal conductivity components from thin films. Abstract Directional characterization of
