Signatures of hermitian forms and "prime ideals" of Witt groups

open access: yes, 2015
In this paper a further study is made of $H$-signatures of hermitian forms, introduced previously by the authors. It is shown that a tuple of reference forms $H$ may be replaced by a single form and that the $H$-signature is invariant under Morita ...

Sequelae of child maltreatment: Umbrella synthesis of 148 meta‐analyses on the mental health correlates

open access: yesJCPP Advances, EarlyView.
Our umbrella synthesis found strong, often equivalent, associations between child maltreatment and all examined mental health difficulties. Different types of maltreatment appear to have comparably negative effects on mental health. If replicated, these findings may cause us to reconsider conventional wisdom that suggests some forms of CM are less ...

On the Structure of Weyl-Type, Witt-Type, and Non-Associative Algebras over Expolynomial Rings

open access: yesMathematics
This paper introduces a generalized class of Weyl-type, Witt-type, and non-associative algebras constructed over an exponential–polynomial (expolynomial) framework.

Effects of Deep Brain Stimulation on Adductor Laryngeal Dystonia

open access: yesThe Laryngoscope, EarlyView.
This study evaluated how globus pallidus interna (GPi) versus ventral intermediate nucleus (VIM) deep brain stimulation (DBS) affects objective voice measures in patients with adductor laryngeal dystonia. GPi‐DBS was associated with greater improvements in voicing, voice breaks, and intensity modulation, while VIM‐DBS showed greater improvement in ...

Witt’s Hyperbola Is Both Predicted and Observed to Pass Close to the Lensing Galaxies in Quadruple Quasars

open access: yesThe Astrophysical Journal
When a rectangular hyperbola is constructed from the image positions of a quadruply lensed quasar, as proposed by Witt, it passes very close to the lensing galaxy. The median measured perpendicular offset between the observed light center of the lens and

Witt ring localized

open access: yes, 2020
The rings of $p$-typical Witt vectors are interpreted as spaces of vanishing cycles for some perverse sheaves over a disc. This allows to "localize"\ an isomorphism emerging in Drinfeld's theory of prismatization [Dr], Prop. 3.5.1, namely to express it as "an integral"\ of a standard exact triangle on the disc.

Harrison's Witt Ring of a Generalized Valuation Ring [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
The purpose of this paper is to determine the relations between H ( R ) H(R) (Harrison’s Witt ring given by generators and relations over a generalized valuation ring R R ) and W ( K ) W(K) (classical Witt ring of inner product spaces over ...

Exploring Suicide Prevention Gatekeeper Interventions for Schools: A Scoping Review

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT Background Among teenagers and young adults, suicide represents a significant public health challenge. Schools are critical for suicide prevention due to the significant time adolescents spend there. Gatekeeper training (GKT) has shown promise in increasing awareness and knowledge, but its implementation‑relevant characteristics and contextual

Quantum Drinfeld Hecke Algebras

open access: yes, 2013
We consider finite groups acting on quantum (or skew) polynomial rings. Deformations of the semidirect product of the quantum polynomial ring with the acting group extend symplectic reflection algebras and graded Hecke algebras to the quantum setting ...
