Bijections between noncrossing and nonnesting partitions for classical reflection groups [PDF]

Discrete Mathematics & Theoretical Computer Science, 2009
We present $\textit{type preserving}$ bijections between noncrossing and nonnesting partitions for all classical reflection groups, answering a question of Athanasiadis and Reiner. The bijections for the abstract Coxeter types $B$, $C$ and $D$ are new in

Submaximal factorizations of a Coxeter element in complex reflection groups [PDF]

Discrete Mathematics & Theoretical Computer Science, 2011
When $W$ is a finite reflection group, the noncrossing partition lattice $NC(W)$ of type $W$ is a very rich combinatorial object, extending the notion of noncrossing partitions of an $n$-gon.

The Brownian Castle

Communications on Pure and Applied Mathematics, Volume 76, Issue 10, Page 2693-2764, October 2023., 2023
Abstract We introduce a 1+1‐dimensional temperature‐dependent model such that the classical ballistic deposition model is recovered as its zero‐temperature limit. Its ∞‐temperature version, which we refer to as the 0‐Ballistic Deposition (0‐BD) model, is a randomly evolving interface which, surprisingly enough, does not belong to either the Edwards ...

An innovative operation‐time‐space network for solving different logistic problems with capacity and time constraints

Networks, Volume 78, Issue 3, Page 350-367, October 2021., 2021
Abstract This work describes an innovative operation‐time‐space network that can be easily adapted to model different logistic problems involving time and space decisions. In the recent literature, different time‐space networks have been proposed to deal with specific requirements of problems arising in the logistic and transportation fields.

Adjusted Extreme Conditional Quantile Autoregression with Application to Risk Measurement

Journal of Probability and Statistics, Volume 2021, Issue 1, 2021., 2021
In this paper, we propose an extreme conditional quantile estimator. Derivation of the estimator is based on extreme quantile autoregression. A noncrossing restriction is added during estimation to avert possible quantile crossing. Consistency of the estimator is derived, and simulation results to support its validity are also presented.

Dynamic Path Flow Estimation Using Automatic Vehicle Identification and Probe Vehicle Trajectory Data: A 3D Convolutional Neural Network Model

Journal of Advanced Transportation, Volume 2021, Issue 1, 2021., 2021
Dynamic path flows, referring to the number of vehicles that choose each path in a network over time, are generally estimated with the partial observations as the input. The automatic vehicle identification (AVI) system and probe vehicle trajectories are now popular and can provide rich and complementary trip information, but the data fusion was rarely

Low‐Refractive Index Layers in Organic Light‐Emitting Diodes via Electrospray Deposition for Enhanced Outcoupling Efficiencies

Advanced Engineering Materials, Volume 22, Issue 5, May 2020., 2020
Nanoporous and conductive hole‐transport layers (HTLs) with a reduced effective refractive index are realized using the simple method of electrospray deposition. Optical simulations for devices incorporating such layers suggest a more efficient light extraction. Based on simulation, devices with a reduced refractive index HTL are fabricated and yield a

Analysis of Hydraulic Fracture Propagation Using a Mixed Mode and a Uniaxial Strain Model considering Geomechanical Properties in a Naturally Fractured Shale Reservoir

Geofluids, Volume 2020, Issue 1, 2020., 2020
This study proposes a hydraulic fracture propagation model with a mixed mode comprising opening and sliding modes to describe a complex fracture network in a naturally fractured shale gas formation. We combine the fracture propagation model with the mixed mode and the uniaxial strain model with tectonic impacts to calculate the stress distribution ...
