Relic abundance of dark matter is investigated in the framework of universal extra dimension models with right-handed neutrinos. These models are free from the serious Kaluza-Klein (KK) graviton problem that the original universal extra dimension model has. The first KK particle of the right-handed neutrino is a candidate for dark matter in this framework, and its relic abundance is determined ...

The KK/Ta mouse strain serves as a suitable polygenic model for human type 2 diabetes. Using 93 microsatellite markers in 208 KK/Ta x (BALB/c x KK/Ta)F1 male backcross mice, we carried out a genome-wide linkage analysis of KK/Ta alleles contributing to type 2 diabetes and related phenotypes, such as obesity and dyslipidemia. We identified three major chromosomal intervals significantly contribu...

We show how methods from K-theory of operator algebras can be applied in a completely algebraic setting to define a bivariant, M∞-stable, homotopy-invariant, excisive Ktheory of algebras over a fixed unital ground ring H, (A, B) 7→ kk∗(A, B), which is universal in the sense that it maps uniquely to any other such theory. It turns out kk is related to C. Weibel’s homotopy algebraic K-theory, KH....

Two different BALB/c anti-CBA (H-2k)monoclonal antibodies that bind to Kk and Dk antigens blocked Tc cell-mediated lysis of L929 (Kk, Dk) target cells, but with quite different specificity. One antibody (30R3) powerfully blocked Kk-specific lysis mediated by alloreactive or Kk-restricted Tc cells immune to ectromelia, Sendai, or influenza viruses. The other antibody (27R9) blocked these anti-Kk...

BACKGROUND The new Diagnostic and Statistical Manual of Mental Disorders (fifth edition, DSM-5) redefined the boundaries of autism as a spectrum. It has been reported that the number of schoolchildren with undiagnosed developmental disorders (DDs) has risen in Japan. Such children referred to as kininaru-kodomo (KK, "children of concern") by healthcare professionals fall into a gray area. There...

An asymmetric thick domain wall solution with de Sitter (dS) expansion in five dimensions can be constructed from a symmetric one by using a same scalar (kink) with different potentials. In this paper, by presenting the mass-independent potentials of Kaluza–Klein (KK) modes in the corresponding Schrödinger equations, we investigate the localization and mass spectra of various bulk matter fields...

In extensions of the standard model (SM) with d extra dimensions at the TeV scale the virtual exchange of Kaluza-Klein (KK) excitations of the gauge bosons gives contributions that change the SM relations between electroweak observables. These corrections are finite only for d = 1; for d ≥ 2 the infinite tower of KK modes gives a divergent contribution that has to be regularized introducing a c...

The K region of H-2 controls the Tc cell response to vaccinia-Db. The Kb, Kd, and Kq alleles allow good Tc cell responses against vaccinia-Db. In contrast, the presence of Kk in H-2 recombinants 2R (Kk,Db) and 4R (Kk,Db) or in F1 hybrids greatly reduces the anti-vaccinia-Db response. The defect does not lie in antigen presentation, as infected 4R cells can stimulate anti-vaccinia-Db Tc cells in...

A graph G is Ramsey for H if every two-colouring of the edges of G contains a monochromatic copy of H. Two graphs H and H ′ are Ramsey-equivalent if every graph G is Ramsey for H if and only if it is Ramsey for H ′. In this paper, we study the problem of determining which graphs are Ramsey-equivalent to the complete graph Kk. A famous theorem of Nešetřil and Rödl implies that any graph H which ...
