Transportation of diffuse random measures on $\mathbb{R}^d$ [PDF]

arXiv, 2021
We consider two jointly stationary and ergodic random measures $\xi$ and $\eta$ on $\mathbb{R}^d$ with equal finite intensities, assuming $\xi$ to be diffuse. An allocation is a random mapping taking $\mathbb{R}^d$ to $\mathbb{R}^d\cup\{\infty\}$ in a translation invariant way. We construct allocations transporting the diffuse $\xi$ to arbitrary $\eta$,

Variance Allocation and Shapley Value

, 2017
Motivated by the problem of utility allocation in a portfolio under a Markowitz mean-variance choice paradigm, we propose an allocation criterion for the variance of the sum of $n$ possibly dependent random variables.

Open‐source deep‐learning models for segmentation of normal structures for prostatic and gynecological high‐dose‐rate brachytherapy: Comparison of architectures

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The use of deep learning‐based auto‐contouring algorithms in various treatment planning services is increasingly common. There is a notable deficit of commercially or publicly available models trained on large or diverse datasets containing high‐dose‐rate (HDR) brachytherapy treatment scans, leading to poor performance on images ...

Music Interventions in Hyperacute and Acute Stroke Patients: A Randomized Controlled Pilot Feasibility Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Music interventions have been shown to have beneficial effects on hemodynamic parameters, pain, and anxiety in various medical settings. However, music interventions in the setting of acute stroke have not been studied. The objective of this trial was to perform a pilot feasibility study of music interventions in the setting of acute

Random-allocation and urn models

Journal of Applied Probability, 2004
We review some urn and random-allocation models, mostly using probability generating function (PGF) methods. We begin by formulating a basic problem which can be thought of as either an urn or a random-allocation model; a PGF solution to it is outlined.

Combination Therapy With Vigabatrin and Prednisolone Versus Vigabatrin Alone for Infantile Spasms

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The study evaluated the effectiveness of combination therapy with vigabatrin and prednisolone versus vigabatrin alone for treating infantile epileptic spasms syndrome (IESS). Methods This single‐center, single‐blind, randomized trial enrolled infants aged 2–14 months with new‐onset IESS, randomly assigned them (1:1) to receive either

On the efficiency and optimality of random allocations

Journal of Mathematical Analysis and Applications, 1985
AbstractAllocations in a random economy described by an integrably bounded, closed and convex valued, measurable consumption multifunction and a monotone, continuous utility function are studied. The notions of efficiency and optimality of allocations are introduced and compared.

A Limit Theorem for Random Allocations

Journal of Mathematics Research, 2012
A limit theorem is presented for random allocations. For a fixed period we allocate $m$ balls into $N$ boxes. We repeat the experiment throughout $n$ periods. Let $p_q$ denote the probability that we do not place more than $q$ balls  into any of the $N$ boxes during any of the $n$ repetitions. The limit of $p_q$ is determined when $m,n,N \to \infty$.

Home‐Based Tele‐tDCS in Amyotrophic Lateral Sclerosis: Feasibility, Safety, and Preliminary Efficacy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options. Transcranial direct current stimulation (tDCS) shows promise as a neuromodulatory intervention in various neurological disorders, but its application in ALS, particularly in a remote, home‐based format, remains underexplored.

Differential allocation by female zebrafish (Danio rerio) to different-sized males--an example in a fish species lacking parental care. [PDF]

PLoS ONE, 2012
Organisms allocate resources to reproduction in response to the costs and benefits of current and future reproductive opportunities. According to the differential allocation hypothesis, females allocate more resources to high-quality males.
