The human has two relaxins, termed H1 and H2, both of which are biologically active and co-expressed in the decidua, placenta and prostate; in the corpus luteum, the main source of circulating relaxin, only the H2 form is expressed. The reasons for this differential expression of the relaxin genes are unknown. The possibility that their 3'-untranslated regions (UTRs) contribute to this differen...

To obtain a contradiction, suppose that there is a cycle; this implies that so that there are q ≥ 2 different governments H1, . . . ,Hq such that φ (Hj) = Hj+1 for all 1 ≤ j < q, and φ (Hq) = H1. Without loss of generality, let H1 be the least competent of these governments. Take H = φ (H2) (if q > 2 then H = H3 and if q = 2 then H = H1). As φ is a political equilibrium, Vi (H) > Vi (H2) holds ...

Given bipartite graphs H1 and H2, the bipartite Ramsey number b(H1;H2) is the smallest integer b such that any subgraph G of the complete bipartite graph Kb,b, either G contains a copy of H1 or its complement relative to Kb,b contains a copy of H2. It is known that b(K2,2;K2,2) = 5, b(K2,3;K2,3) = 9, b(K2,4;K2,4) = 14 and b(K3,3;K3,3) = 17. In this paper we study the case H1 being even cycles a...

A graph is (H1,H2)-free for a pair of graphsH1, H2 if it contains no induced subgraph isomorphic toH1 orH2. In 2001, Král’, Kratochvíl, Tuza, and Woeginger initiated a study into the complexity of Colouring for (H1,H2)free graphs. Since then, others have tried to complete their study, but many cases remain open. We focus on those (H1,H2)-free graphs where H2 is H1, the complement of H1. As thes...

The glottal open quotient (OQ) is often associated with the amplitude of the first source harmonic relative to the second (H1*H2*), which is assumed to be one cause of a change in vocal quality along a breathy-to-pressed continuum. The association between OQ and H1*-H2* was investigated in a group of 5 human subjects and also in a computational voice production simulation. The simulation incorp...

For simplicity, we adopt the following rules: n denotes an element of N, X, X1 denote sets, r, p denote real numbers, s, x0, x1, x2 denote real numbers, S, T denote real normed spaces, f , f1, f2 denote partial functions from R to the carrier of S, s1 denotes a sequence of real numbers, and Y denotes a subset of R. The following propositions are true: (1) Let s2 be a sequence of real numbers an...

We prove higher integrability and differentiability results for local minimizers u: R2 ⊃ Ω → RM , M ≥ 1, of the splitting-type energy Ω[h1(|∂1u|) + h2(|∂2u|)] dx. Here h1, h2 are rather general N -functions and no relation between h1 and h2 is required. The methods also apply to local minimizers u: R2 ⊃ Ω → R2 of the functional ∫ Ω[h1(|div u|) + h2(|ε(u)|)] dx so that we can include some varian...

Lateral mobility studies comparing native and mutated membrane proteins, combined with treatments that alter clathrin lattice structure, can measure membrane protein-coated pit interactions in intact cells (Fire, E., Zwart, D., Roth, M. G., and Henis, Y. I. (1991) J. Cell Biol. 115, 1585-1594). We applied this approach to study the interactions of the H1 and H2 human asialoglycoprotein receptor...
