A Polycyclic Quotient Algorithm

open access: yesJournal of Symbolic Computation, 1997
AbstractThis paper describes a generalization of the Gröbner basis method to the integral group ring of a polycyclic group. A polycyclic quotient algorithm is developed using this method. SupposeGis a group given by a finite presentation andG(n)is thenth term in the derived series ofG. A polycyclic quotient algorithm computes the quotientG/G(n)if it is

Rest‐activity rhythm phenotypes in adults with epilepsy and intellectual disability

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Rest‐activity rhythms (RARs) are perturbed in many forms of neuropsychiatric illness. In this study, we applied wrist actigraphy to describe RAR perturbations in intellectually disabled adults with epilepsy (“E + ID”), using a cross‐sectional case–control design.

Dynamic electro‐clinical features in Guanidinoacetate N‐methyltransferase deficiency: A familial case series

open access: yesEpilepsia Open, EarlyView.
Abstract Guanidinoacetate N‐methyltransferase deficiency is an inborn error of creatine metabolism, responsible for the absent conversion of guanidinoacetic acid into creatine, resulting in cerebral creatine deficit. It could present a variety of symptoms such as neurodevelopmental delay, epilepsy, movement disorder (ataxia, dystonia, and chorea), and ...

Heavy Metal Bioaccumulation in Solanum torvum (Sw.) (Turkey Berry) From the Bono and Ahafo Regions: Nutritional Potential and Toxicological Risks

open access: yesFood Safety and Health, EarlyView.
ABSTRACT Heavy metal contamination of agricultural soils and subsequent bioaccumulation in food crops poses significant public health concerns, particularly in mining regions. This study investigated heavy metal concentrations in turkey berry (Solanum torvum) fruits and associated soils from three locations in Ghana's mining belt, evaluated soil ...
