We study geometric limits of convex-cocompact cyclic subgroups the rank 1 groups SO_0(1, k+1) and SU(1, k+1). construct examples sequences such G that converge algebraically whose limit strictly contains algebraic limit, thus generalizing example first described by Jorgensen for SO_0(1,3). also give necessary sufficient conditions a subgroup to arise as sequence subgroups. then discuss generali...

In this paper we study the connections between cyclic presentations of groups and branched cyclic coverings of (1, 1)-knots. In particular , we prove that every n-fold strongly-cyclic branched covering of a (1, 1)-knot admits a cyclic presentation for the fundamental group encoded by a Heegaard diagram of genus n.

objective: endothelium is a selective and permeable membrane for transferring nutrients and vital components to arterial wall. endothelial damage might lead to altered biological function of endothelium and clinical consequences such as atherosclerosis. blood pressure pulse always exerts circumferential tension to the arterial wall. hence, such tension together with other loads, play important ...

in this study, a researching program is conducted by cyclic triaxial test to determine the post-cyclic behavior of bushehr carbonate sand retrieved from the north of the persian gulf, under anisotropic consolidation at 200 kpa confining pressure. the article compares the post-cyclic monotonic strength and excess pore water pressures generated after the test with the pre-cyclic monotonic results...

Cyclic AMP and cyclic GMP were released into the growth medium of mycelia of Neurospora crassa wild-type strains St.L.74A and Em5297a and by white collar-1 and white collar-2 mutant strains. After growth for 6 days at 18 degrees C, there were 2.19 (St.L.74A), 5.83 (Em5297a), 1.38 (white collar-1), and 1.10 (white collar-2) nanomoles of cyclic AMP per gram dry weight of mycelia in the growth med...

abstract: this paper presents the results of pullout tests on uniaxial geogrid embedded in silica sand under monotonic and cyclic pullout forces. the new testing device as a recently developed automated pullout test device for soil-geogrid strength and deformation behavior investigation is capable of applying load/displacement controlled monotonic/cyclic forces at different rates/frequencies an...

Results of an experimental investigation of the seismic performance of prefabricated column-footing connections are presented. Tests were conducted on six 1/4-scale prefabricated column specimens inserted into prefabricated footings in two Groups. Group-1 consisted of four specimens, which were tested under constant axial load and cyclic inelastic lateral displacements. The remaining two specim...

Let A be the path algebra of a Dynkin quiver Q over finite field, and P category projective A-modules. Denote by C1(P) 1-cyclic complexes P, n˜+ vector space spanned isomorphism classes indecomposable non-acyclic objects in C1(P). In this paper, we prove existence Hall polynomials C1(P), then establish relationship between numbers for therein those Using evaluated at 1, define Lie bracket commu...
