Introduction: Simultaneous acquisition of EEG and functional MRI (fMRI) data has proven to be a powerful technique to investigate the location and dynamics of epileptiform networks associated with interictal epileptic discharges (IED). However, in most analyses for IED, EEG dominates fMRI, i.e. the EEG determines the onsets of the IED events in the general linear model (GLM) fMRI analysis (1, 2...

M e t h o d s Data sources: PubMed and the Cochrane Library. Study selection and assessment: Randomized controlled trials (RCTs) that compared β-blockers as first-line treatment with placebo, no treatment, or other antihypertensive drugs in patients with primary hypertension, and evaluated all-cause mortality, cardiovascular morbidity, or both. Subgroup analyses were conducted for nonatenolol β...

in this paper, we study the notion of solvable $l$-subgroup of an $l$-group and provide its level subset characterization and this justifies the suitability of this extension. throughout this work, we have used normality of an $l$-subgroup of an $l$-group in the sense of wu rather than liu.

suppose that $h$ is a subgroup of $g$‎, ‎then $h$ is said to be‎ ‎$s$-permutable in $g$‎, ‎if $h$ permutes with every sylow subgroup of‎ ‎$g$‎. ‎if $hp=ph$ hold for every sylow subgroup $p$ of $g$ with $(|p|‎, ‎|h|)=1$)‎, ‎then $h$ is called an $s$-semipermutable subgroup of $g$‎. ‎in this paper‎, ‎we say that $h$ is partially $s$-embedded in $g$ if‎ ‎$g$ has a normal subgroup $t$ such that $ht...

The chiral hypermaps with at most four hyperfaces were classified in [A. Breda d’Azevedo and R. Nedela,Chiral hypermaps with few hyperfaces, Math. Slovaca, 53 (2003), n.2, 107–128]. It arises from this classification that all chiral hypermaps are “canonical metacyclic”, that is, the one-step rotation about a hypervertex, or about a hyperedge, or about a hyperface, generates a normal subgroup in...

The EPDiff equation for geodesic flow on the diffeomorphisms admits a remarkable ansatz for its singular solutions, called “diffeons.” Because this solution ansatz is a momentum map, the diffeons evolve according to canonical Hamiltonian equations. We examine diffeon solutions on Einstein spaces that are “mostly” symmetric, i.e., whose quotient by a subgroup of the isometry group is 1-dimension...

This meta-analysis aimed to compare the short- and long-term outcomes in patients undergoing combined coronary endarterectomy and coronary artery bypass grafting (CE + CABG) versus isolated CABG, and particularly to examine subgroup patients with high-risk profile and patients with diffuse disease in the left anterior descending artery (LAD).Studies published between January 1, 1970 and May 31,...

For any finite graph Γ and any field K of characteristic unequal to 2 we construct an algebraic variety X over K whose K-points parameterise K-Lie algebras generated by extremal elements, corresponding to the vertices of the graph, with prescribed commutation relations, corresponding to the non-edges. After that, we study the case where Γ is a connected, simply laced Dynkin diagram of finite or...

Given a group-invariant quasi-free state on the algebra of canonical commutation relations (CCR), we show how group averaging techniques can be used to obtain a symmetry reduced CCR algebra and reduced quasi-free state. When the group is compact this method of symmetry reduction leads to standard results which can be obtained using other methods. When the group is non-compact the group averagin...

The canonical height ĥ on an abelian variety A defined over a global field k is an object of fundamental importance in the study of the arithmetic of A. For many applications it is required to compute ĥ(P ) for a given point P ∈ A(k). For instance, given generators of a subgroup of the Mordell-Weil group A(k) of finite index, this is necessary for most known approaches to the computation of gen...
