The Anatomical Record, Volume 309, Issue 11, Page 3375-3396, November 2026.Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Multivariate analysis of variance with fewer observations than the dimension
In this article, we consider the problem of testing a linear hypothesis in a multivariate linear regression model which includes the case of testing the equality of mean vectors of several multivariate normal populations with common covariance matrix ...

Non-stationary Variance and Volatility Causality [PDF]
This paper aims to describe bias estimates when non-stationary variance is not detected. We first present a theoretical multivariate GARCH model with structural changes in variance. Then we describe the non-stationary variance and Volatility Causality in

Dyslexia, Volume 32, Issue 4, November 2026.ABSTRACT The present study examined neurocognitive differences in visual word processing between children with reading difficulties (RD) and chronological‐age‐matched controls (CA) using event‐related potentials (ERPs) during a lexical decision task. Participants were Grade 3 and Grade 6 children (ages 7.6–12.1 years) who were required to discriminate ...

It is well known that the best equivariant estimator of the variance covariance matrix of the multivariate normal distribution with respect to the full affine group of transformation is not even minimax. Some minimax estimators have been proposed.

Classical and robust methods of MANOVA analysis
, 2019 Daudzdimensiju dispersiju analīze (MANOVA) tiek pielietota situācijās, kad tiek mērīti vairāki mainīgie katrai eksperimentālai vienībai. Darbā aplūkota teorija par klasisko MANOVA metodi un robusto MANOVA metodi, to pieņēmumiem un pielietojumiem.

International Journal of Eating Disorders, Volume 59, Issue 11, Page 2543-2548, November 2026.ABSTRACT Objective Available studies comparing clinical features in treatment‐seeking adults with avoidant/restrictive food intake disorder (ARFID) to anorexia nervosa (AN) often do not distinguish between AN‐restricting (AN‐R) and AN‐binge‐eating/purging (AN‐B/P) subtypes, rely on retrospective ARFID diagnoses, and include unequal group sizes.

Ecology and Evolution, Volume 16, Issue 11, November 2026.Recent appearance of a mixed species outbreak of coral‐eating crown‐of‐thorns sea stars Acanthaster cf. solaris and the lesser‐known Acanthaster brevispinus in the tropical to subtropical transition zone in eastern Australia have caused management concern due to the potential of hybridisation.

Ecology and Evolution, Volume 16, Issue 11, November 2026.Small mammals in hot climates depend on shelter to survive high daytime temperatures. We show that rufous bettongs construct grass nests that cut daytime temperature extremes by more than 20°C, and that this buffering holds wherever they build, including in the open.

Infant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 6, November 2026.Abstract Maternal representations of the child begin forming during pregnancy and evolve through interactions with the baby. Research suggests that prenatal representations may have a more stable impact on parenting than postnatal representations, but their long‐term impact remains unclear.
