The maximal subgroups of the classical groups in dimension 13, 14 and 15 [PDF]

open access: yes, 2015
One might easily argue that the Classification of Finite Simple Groups is one of the most important theorems of group theory. Given that any finite group can be deconstructed into its simple composition factors, it is of great importance to have a ...

Orthogonal bases of Brauer symmetry classes of tensors for groups having cyclic support on non-linear Brauer characters [PDF]

open access: yes, 2016
This paper provides some properties of Brauer symmetry classes of tensors. A dimension formula is derived for the orbital subspaces in the Brauer symmetry classes of tensors corresponding to the irreducible Brauer characters of the groups whose non ...

Symmetric Presentations of Coxeter Groups [PDF]

open access: yes, 2011
We apply the techniques of symmetric generation to establish the standard presentations of the finite simply laced irreducible finite Coxeter groups, that is, the Coxeter groups of types An, Dn and En, and show that these are naturally arrived at purely ...

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.

Quadratic forms and Brauer groups

open access: yes, 2020
The Clifford algebras provide a connection between the study of quadratic forms and the Brauer group. We explain how a bound for the u-invariant of a field can be given purely in terms of certain period-index bounds for the Brauer group. We survey some

Brauer groups of singular del Pezzo surfaces [PDF]

open access: yes, 2013
We describe the effect of rational singularities on the Brauer group of a surface, and compute the Brauer groups of all singular del Pezzo surfaces over an algebraically closed field.FWN – Publicaties zonder aanstelling Universiteit ...

A bioinspired catalytic nanoplatform for ferroptosis‐immunotherapy synergy in metastatic cancer

open access: yesBMEMat, EarlyView.
The bioinspired nanoplatform MnMSN@MnP‐PEG co‐delivers manganese peroxidase and manganese ions to synergistically induce immunogenic ferroptosis and activate the cGAS‐STING pathway, eliciting potent antitumor immunity against primary and metastatic tumors.

Animal empathy reconsidered: a multidimensional profile account

open access: yesBiological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)
