Inequalities for general mixed affine surface areas [PDF]
Journal of London Mathematics Society, 85 (2012) 101-120, 2011 Several general mixed affine surface areas are introduced. We prove some important properties, such as, affine invariance, for these general mixed affine surface areas. We also establish new Alexandrov-Fenchel type inequalities, Santal\'{o}-type inequalities, and affine isoperimetric inequalities for these general mixed affine surface areas.

Frontiers in Immunology, 2018 Effector and memory CD8 T cells have an intrinsic difference in the way they must approach antigen; effector cells need to address the pathogen at hand and therefore favor outgrowth of only high-affinity clones. In contrast, the memory pool benefits from

Journal of Combinatorial Theory, Series A, 1995 AbstractLet P be a projective space and consider a geometric hyperplane H of the Grassmannian of k-dimensional subspaces of P, where k is some integer. We give a diagram-theoretic characterization of the affine Grassmann geometry of all the subspaces of P containing or contained in a member of the complement of H.

Prevalent and persistent new-onset autoantibodies in mild to severe COVID-19
Nature CommunicationsAutoantibodies have been shown to be implied in COVID-19 but the emerging autoantibody repertoire remains largely unexplored. We investigated the new-onset autoantibody repertoire in 525 healthcare workers and hospitalized COVID-19 patients at five time ...

Affine twist deformation of a sphere with holes [PDF]
Geom Dedicata (2016) 182:249--262, 2015 In this paper, we introduce a new parameter, the affine twist parameter for the affine deformation of a sphere with holes. We show that the affine deformation space can be parametrized by Margulis invariants and affine twist parameters. The affine twist parameter is canonically regarded as a correspondence to the Fenchel-Nielsen twist parameter in ...

Arthur Ransome and Dmitri Mitrokhin: Translating the Russian Folktale
Journal of Language and Education, 2016 This paper focuses on Arthur Ransome’s and Dmitri Mitrokhin’ s collaboration in translating the Russian folktales. Old Peter’s Russian Tales (1916), Ransome’ s first serious (and sustained) success, was the translation product of his early sojourns in ...

Biological and immunochemical properties of polyreactive immunoglobulins [PDF]
The Ukrainian Biochemical Journal, 2015 A previously unknown phenomenon of acquired polyreactivity of serum immunoglobulins, which were subject to the effect of concentrated solutions of chaotropic ions, such as KSCN (3.0-5.0 M), low/high pH (pH 2.2-3.0), or heating to 58-60 °C, was originally

Affine differential geometry and affine rotation surfaces: algebraic surfaces invariant under non-Euclidean affine rotations [PDF]
arXiv, 2018 Affine rotation surfaces are a generalization of the well-known surfaces of revolution. Affine rotation surfaces arise naturally within the framework of affine differential geometry, a field started by Blaschke in the first decades of the past century.
