Let G be a countable discrete group. Call two subgroups H1 and H2 of G commensurable if H1 ∩H2 has finite index in both H1 and H2. We say that an action of G on a discrete set X has noncommensurable stabilizers if the stabilizers of any two distinct points of X are not commensurable. We prove in this paper that the action of the mapping class group on the complex of curves has noncommensurable ...

A webpage with 376 objects of size 1 KB each. A webpage with 10 objects of size 435 KB each. A webpage with 136 objects of size 1 KB to 620 KB each. ● Page load times (PLTs) over h2 are lower than PLTs over h1, because in the case of h1 with 6 TCP connections the server can send at most 6 objects in parallel. ● Whereas in the case of h2 with many streams multiplexed onto single connection, the ...

Given two graphs H1 and H2, a graph is (H1,H2)-free if it contains no induced subgraph isomorphic to or H2. Let Pt be the path on t vertices. A bull obtained from triangle with disjoint pendant edges. In this paper, we show that there are finitely many 5-vertex-critical (P5, bull)-free graphs.

We study some problems pertaining to the tournament equilibrium set (τ for short). A tournament H is a τ-retentive tournament if there is a tournament T which has a minimal τ-retentive set R such that T [R] is isomorphic to H. We study τ-retentive tournaments and achieve many significant results. In particular, we prove that there are no τretentive tournaments of size 4, only 2 non-isomorphic τ...

The problem of mixed H2/H1 control is considered for a class of uncertain discrete-time nonlinear stochastic systems. The nonlinearities are described by statistical means of the stochastic variables and the uncertainties are represented by deterministic norm-bounded parameter perturbations. The mixed H2/H1 control problem is formulated in terms of the notion of exponentially mean-square quadra...

Axoplasmic vesicles that translocate on isolated microtubules in an ATP-dependent manner have an associated ATP-binding polypeptide with a previously estimated relative molecular mass of 292 kD (Gilbert, S. P., and R. D. Sloboda. 1986. J. Cell Biol. 103:947-956). Here, data are presented showing that this polypeptide (designated H1) and another high molecular mass polypeptide (H2) can be isolat...

The objective of the study was to investigate the relationship between health and production traits in chickens. The data were obtained from a closed, fully pedigreed, commercial broiler line. Records included measurements of body weight (BW), residual feed intake (RFI), percent breast meat (PBM), and two health traits (H1 and H2) from 13,665 birds and 1,524 hens with progeny records. Productio...

Induction of the B7 family molecules by 12-O-tetradecanoyl phorbol 13-acetate (TPA) has been reported, however, the mechanism by which TPA up-regulates these molecules remains poorly understood. In this study, the expression of B7-DC, -H1, -H2, and -H3 in response to TPA was markedly induced in K562 cells. TPA also induced activation of ERK, p38 mitogen-activated protein kinase (MAPK), JNK, pho...

BACKGROUND The human asialoglycoprotein receptor (ASGPR) is composed of two polypeptides, designated H1 and H2. While variants of H2 have been known for decades, the existence of H1 variants has never been reported. PRINCIPAL FINDINGS We identified two splice variants of ASGPR H1 transcripts, designated H1a and H1b, in human liver tissues and hepatoma cells. Molecular cloning of ASGPR H1 vari...
