The Dade group of a fusion system. [PDF]

open access: yes, 2009
We define the notion of the Dade group of a fusion system and show that some of the gluing and detection results for Dade groups of finite p-groups due to Bouc and Thévenaz in [S. Bouc and J. Thévenaz. Gluing torsion endo-permutation modules. (Preprint.)]

An efficient high dimensional quantum Schur transform [PDF]

open access: yesQuantum, 2019
The Schur transform is a unitary operator that block diagonalizes the action of the symmetric and unitary groups on an $n$ fold tensor product $V^{\otimes n}$ of a vector space $V$ of dimension $d$.

Endo-permutation modules as sources of simple modules. [PDF]

open access: yes, 2003
The source of a simple $kG$-module, for a finite $p$-solvable group $G$ and an algebraically closed field $k$ of prime characteristic $p$, is an endo-permutation module (see~\cite{Pu1} or~\cite{Th}). L.

The Dade group of a metacyclic $p$-group. [PDF]

open access: yes, 2003
The Dade group $D(P)$ of a finite $p$-group $P$, formed by equivalence classes of endo-permutation modules, is a finitely generated abelian group. Its torsion-free rank equals the number of conjugacy classes of non-cyclic subgroups of $P$ and it is ...

Topics in computational group theory : primitive permutation groups and matrix group normalisers [PDF]

open access: yes, 2012
Part I of this thesis presents methods for finding the primitive permutation groups of degree d, where 2500 ≤ d < 4096, using the O'Nan-Scott Theorem and Aschbacher's theorem. Tables of the groups G are given for each O'Nan-Scott class.

Minimal and random generation of permutation and matrix groups [PDF]

open access: yes, 2012
We prove explicit bounds on the numbers of elements needed to generate various types of finite permutation groups and finite completely reducible matrix groups, and present examples to show that they are sharp in all cases.

Implementing a Class of Permutation Tests: The coin Package [PDF]

open access: yes, 2007
The R package coin implements a unified approach to permutation tests providing a huge class of independence tests for nominal, ordered, numeric, and censored data as well as multivariate data at mixed scales.

Permutation inference for the general linear model [PDF]

open access: yes, 2014
Permutation methods can provide exact control of false positives and allow the use of non-standard statistics, making only weak assumptions about the data.

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

Abatacept for Prophylaxis of Acute and Chronic Graft‐Versus‐Host‐Disease in Children Undergoing Allogeneic Hematopoietic Stem Cell Transplantation—A Systematic Review and Meta‐Analysis of Cohort Studies

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.
