Measure‐valued processes for energy markets
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Electromyographic Assessment of Sleep Bruxism in Patients With Periodontitis: A Case–Control Study
ABSTRACT Objective The relationship between periodontitis and bruxism has always been a matter of debate. The aim of the present paper is to investigate the association between advanced stages of periodontitis (Stage III/IV) and the intensity and duration of sleep bruxism events, measured as bruxism work index (BWI) and bruxism time index (BTI) through

Spatial depth for data in metric spaces
Abstract We propose a novel measure of statistical depth, the metric spatial depth, for data residing in an arbitrary metric space. The measure assigns high (low) values for points located near (far away from) the bulk of the data distribution, allowing quantifying their centrality/outlyingness.

A Short Note On M-Symmetric Hyperelliptic Riemann Surfaces
We provide an argument, based on Schottky groups, of a result due to B. Maskit which states a necessary and sufficient condition for the double oriented cover of a planar compact Klein surface of algebraic genus at least two to be a hyperelliptic Riemann

Elementary students' argumentative and explanatory mathematical writing about fractions
Abstract Mathematical writing (MW) is an important yet underutilized form of mathematics discourse. Given the lack of attention to MW, there are few resources to support the implementation and assessment of MW. This study responds to the lack of resources by describing a MW unit focused on fractions that was implemented during a summer school program ...
