ABSTRACT In absence of sufficient data, structured expert judgment is a suitable method to estimate uncertain quantities. While such methods are well established for individual variables, eliciting their dependence in a structured manner is a less explored field of research.

Debiasing piecewise deterministic Markov process samplers using couplings
Abstract Monte Carlo methods—such as Markov chain Monte Carlo (MCMC) and piecewise deterministic Markov process (PDMP) samplers—provide asymptotically exact estimators of expectations under a target distribution. There is growing interest in alternatives to this asymptotic regime, in particular in constructing estimators that are exact in the limit of ...

Is every product system concrete?
Abstract Is every product system of Hilbert spaces over a semigroup P$P$ concrete, that is, isomorphic to the product system of an E0$E_0$‐semigroup over P$P$? The answer is no if P$P$ is discrete, cancellative and does not embed in a group. However, we show that the answer is yes for a reasonable class of semigroups.

The necessity of motoric engagement in enhancing route memory
Abstract The relative contribution of decision‐making and motor engagement at encoding, on route memory, was examined using virtual reality (VR). During encoding, participants explored 12 virtual environments for 40 s each. Navigation strategy during encoding was manipulated within‐subjects.

Developments in Functional Regression Model for Network Structured Data
ABSTRACT In this paper, we propose a Network‐Weighted Functional Regression (NWFR) model, an extension of Spatially Weighted Functional Regression (SWFR) to functional data defined on network‐structured settings. To assess predictive uncertainty, we develop a functional conformal prediction procedure that yields a distribution‐free prediction interval ...

Abundant Neighborhoods, Two‐Sided Markets, and Maximal Matchings
ABSTRACT I introduce a new graph‐theoretic property called abundant neighborhoods. This property is motivated by studying the thickness of economic markets. A vertex is, roughly, guaranteed to match if and only if it has an abundant neighborhood.

Stability of Interdiction Strategies in Quickest Flow Networks
ABSTRACT Many, if not all, societies have experienced natural disasters, public protests, traffic congestion, and the smuggling of dangerous goods, among other similar events. Such decision‐making and managerial problems can be studied using a game‐theoretic approach on specific networks.

A Gaussian Process Regression IV Model for PV Outdoor Data
Each electrical performance measure of PV modules needs to be considered in the context of dynamically changing outdoor conditions. In this paper, we introduce a statistical model based on Gaussian process regressions designed to analyze PV outdoor data aiming to utilize all available information.

Incorporating Causality Into Deep Learning Architectures to Improve Flash Drought Forecasts
Abstract Soil moisture flash droughts present challenges to agriculture and ecosystems, leading to widespread socioeconomic impacts. Predicting and providing early warnings for these events remains difficult. We propose a novel deep learning framework, the ResAttCauRec model, which integrates an attention mechanism and additional causal information ...

Searching for Universality of Turbulence in the Earth's Magnetosphere
Abstract Turbulence in space plasmas remains a fundamental challenge, and Earth's magnetosphere (MSP) offers a natural laboratory for its study. Using high‐resolution magnetic field data from the Magnetospheric Multiscale (MMS) mission, we extend a stochastic Markovian framework to analyze turbulence across 10 diverse magnetospheric regions, including ...
