We introduce the notion of vertex operator superalgebra with enhanced conformal structure, which is a refinement of the notion of vertex operator superalgebra. We exhibit several examples, including a particular one which is self-dual, and whose full symmetry group is a direct product of a cyclic group of order seven with the sporadic simple group of Rudvalis. We thus obtain an analogue of Mons...

We study monomial flocks of quadratic cones of PG(3, q), with emphasis on the case where the flock is semifield, providing some nonexistence and some uniqueness results. In addition, we give a computer-free proof of the existence of the sporadic semifield flock of the quadratic cone of PG(3, 35) (and hence of the sporadic translation ovoid of Q(4, 35)), and relate that flock to the sporadic sim...

OBJECTIVE The objective of this study was to assess the association between colorectal neoplasia and sporadic duodenal adenoma. METHODS A retrospective case control study was conducted using the databases of two major teaching hospitals in Western Australia. The frequency of colorectal neoplasia in patients with sporadic duodenal adenomas was compared with that in a control group of patients ...

The incidence of congenital heart defects (CHDs) reaches 1% all newborns. Of particular importance is the group without a family history and chromosomal disorders, which makes up>80% CHDs. These can be designated as sporadic CHDs, their etiology pathogenesis continue to studied. Aim. To study association cytokine Toll-like receptor (TLR) genes with CHDs in children. Material methods. We exam...

We used [11C]dihydrotetrabenazine, a new ligand for the type 2 vesicular monoamine transporter (VMAT2), with positron emission tomography to study striatal monoaminergic presynaptic terminals in 4 patients with multiple system atrophy, 8 with sporadic olivopontocerebellar atrophy, and 9 normal control subjects. Specific binding in the striatum was significantly reduced in the multiple system at...

BACKGROUND Congenital heart disease (CHD) is the most common birth abnormality, especially for sporadic CHD. However, the etiology of sporadic CHD is largely unknown. NKX2-5, the earliest sign of cardiac progenitor cell differentiation, plays a key role in cardiac morphogenesis, and the mutation of this gene can cause sporadic CHD. PURPOSE To investigate the association of genetic variations ...

Mutations in the Wilms' tumor suppressor gene (WT1) can lead to syndromic forms of steroid-resistant nephrotic syndrome (SRNS) such as Denys-Drash or Frasier syndrome and can cause isolated SRNS. A mutation within WT1 is a frequent cause of sporadic isolated SRNS in girls. In a worldwide cohort of girls, the rate of occurrence was 10.8%. Previous reports have indicated that in Chinese girls, th...

To classify the finite dimensional pointed Hopf algebras with G = McL we obtain the representatives of conjugacy classes of G and all character tables of centralizers of these representatives by means of software GAP. 2000 Mathematics Subject Classification: 16W30,20D06 keywords: GAP, Hopf algebra, sporadic simple group, character. 0. Introduction This article is to contribute to the classifica...
