A Morse index theorem for elliptic operators on bounded domains [PDF]
, 2015 Given a selfadjoint, elliptic operator $L$, one would like to know how the spectrum changes as the spatial domain $\Omega \subset \mathbb{R}^d$ is deformed.

Characterization of ultradifferentiable test functions defined by weight matrices in terms of their Fourier transform [PDF]
, 2016 We prove that functions with compact support in non-quasianalytic classes of Roumieu-type and of Beurling-type defined by a weight matrix with some mild regularity conditions can be characterized by the decay properties of their Fourier transform.

Scanpath Regularity as an Index of Reading Comprehension
Scientific Studies of Reading, 2022 Purpose: Recent research on the potential of using eye-tracking to measure reading comprehension ability suggests that the relationship between standard eye-tracking measures and reading comprehension is influenced by differences in task demands between comprehension assessments.

A semi-quantitative method to denote generic physical activity phenotypes from long-term accelerometer data--the ATLAS index. [PDF]
PLoS ONE, 2013 BACKGROUND: Physical activity is inversely correlated to morbidity and mortality risk. Large cohort studies use wearable accelerometer devices to measure physical activity objectively, providing data potentially relevant to identify different activity ...

Lower bound for the regularity index of fat points
, 2016 The problem to find an upper bound for the regularity index of fat points has been dealt with by many authors. In this paper we give a lower bound for the regularity index of fat points.

Activity Monitoring with a Wrist-Worn, Accelerometer-Based Device
Micromachines, 2018 This study condenses huge amount of raw data measured from a MEMS accelerometer-based, wrist-worn device on different levels of physical activities (PAs) for subjects wearing the device 24 h a day continuously.

Complete intersection vanishing ideals on degenerate tori over finite fields
, 2012 We study the complete intersection property and the algebraic invariants (index of regularity, degree) of vanishing ideals on degenerate tori over finite fields.
