Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.

ON THE THEORY OF BRAID GROUPS

Russian Academy of Sciences. Sbornik Mathematics, 1993
Let \(V\) be a set of (finite) words in an alphabet of variables ranging over elements of a group \(G\). The subgroup \(V(G)\) of the group \(G\) generated by all values of words from \(V\) is called the verbal subgroup defined by the set \(V\). The width of the subgroup \(V(G)\) is defined to be the minimal number \(m \in \mathbb{N} \cup \{+\infty\}\)

A Theory of Bayesian Groups

Noûs, 2017
AbstractA group is often construed as one agent with its own probabilistic beliefs (credences), which are obtained by aggregating those of the individuals, for instance through averaging. In their celebrated “Groupthink”, Russell et al. (2015) require group credences to undergo Bayesian revision whenever new information is learnt, i.e., whenever ...

The Theory of Proportionality as an Abstraction of Group Theory

Mathematische Annalen, 1955
Die Verff. zeigen, daß die Permutation \(\sigma\) der Elemente der Gruppe \(G\) dann und nur dann dem Holomorph von \(G\) angehört, wenn \(\sigma\) die Proportionalitätsrelation \(ab^{-1}=cd^{-1}\) invariant läßt. Weiter geben Verff. eine axiomatische Charakterisierung dieser vierstelligen Proportionalitätsrelation.

The theory of s-groups

Rendiconti del Circolo Matematico di Palermo, 1980
An investigation into an algebraic system with a single binary operation, called a skew-group, based on axioms of associativity; skew-commutativity (x+y+z=x+z+y); right identity; and left inverse. Definitions are given for left coset, quotient skew-group, homorphism, kernel, and subnormal skew-subgroup.
