Effects of oropharyngeal neuromuscular stimulation on the volumetric enlarged and reduced tongue base in minipigs

The Anatomical Record, EarlyView.
Abstract Hypoglossal nerve or tongue protruding muscle stimulation is a current treatment option for obstructive sleep apnea. Thus, the present study analyzed 3D deformations of the volumetric enlarged and reduced tongue base upon oropharyngeal neuromuscular stimulation.

Elliptic Fourier analysis as a tool for the taxonomic identification of isolated theropod pedal phalanges

The Anatomical Record, EarlyView.
Abstract Studies of Upper Cretaceous deposits in North America have provided invaluable insights into the continental ecosystems of this time. Theropod (Saurischia, Dinosauria) pedal phalanges are commonplace in these deposits but can be difficult to identify at a finer taxonomic resolution.

Multivariate measures of skewness and kurtosis for skew-elliptical distributions

Communications in Statistics - Theory and Methods
This article examines eight measures of skewness and the Mardia measure of kurtosis for skew-elliptical distributions. Multivariate measures of skewness considered include Mardia, Malkovich-Afifi, Isogai, Song, Balakrishnan-Brito-Quiroz, Móri-Rohatgi-Székely, Kollo, and Srivastava measures.

Exact Skewness-Kurtosis Tests for Multivariate Normality and Goodness-of-Fit in Multivariate Regressions with Application to Asset Pricing Models [PDF]

, 2003
We study the problem of testing the error distribution in a multivariate linear regression (MLR) model. The tests are functions of appropriately standardized multivariate least squares residuals whose distribution is invariant to the unknown cross ...

Computed Tomography‐Based Morphometric Analysis Reveals Intercondylar Notch Stenosis and Osteophytes Are Associated With Anterior Cruciate Ligament Injury

Arthroscopy, EarlyView.
Purpose To quantitatively assess intercondylar notch morphometrics using 3‐dimensional computed tomography reconstruction, evaluate their association with anterior cruciate ligament (ACL) injury in Asian populations, and investigate the prevalence of osteophytes in patients with ACL injury.

A Flexible Bayesian Semi-Parametric Multivariate Mixed-Effect Model Framework for Skewed Longitudinal Data

Mathematics
While existing mixed-effects models address multivariate outcomes, nonlinearity, or non-normality separately, their joint integration remains limited in medical research.

Van Zwet ordering and the Ferreira-Steel family of skewed distributions [PDF]

There are several procedures to construct a skewed distribution. One of these procedures is based on a symmetric distribution that will be distorted by a skewed distribution defined on (0; 1). This proposal stems from Arellano-Valle et al.

Deep Immunophenotyping Reveals Distinct Immune Signatures in Axial Spondyloarthritis and Psoriatic Arthritis

Arthritis &Rheumatology, Accepted Article.
Objective Axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) are overlapping yet distinct conditions within the spondyloarthritis (SpA) spectrum. As divergent immunophenotypes may influence disease course and therapeutic response, we compared immune cell subsets, cytokine profiles, and inflammatory mediators.

Dynamic Density Forecasts for Multivariate Asset Returns [PDF]

We propose a simple and flexible framework for forecasting the joint density of asset returns. The multinormal distribution is augmented with a polynomial in (time-varying) non-central co-moments of assets.
