The H-force number of a hamiltonian graph G is the smallest number k with the property that there exists a set W ⊆ V (G) with |W | = k such that each cycle passing through all vertices of W is a hamiltonian cycle. In this paper, we determine the H-force numbers of generalized dodecahedra.

Human cervical cancer HeLa cells have functional mitochondria. Recent studies have suggested that mitochondrial metabolism plays an essential role in tumor cell proliferation. Nevertheless, how cells coordinate mitochondrial dynamics and cell cycle progression remains to be clarified. To investigate the relationship between mitochondrial function and cell cycle regulation, the mitochondrial gen...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

Minimum cycle bases of product graphs can in most situations be constructed from minimum cycle bases of the factors together with a suitable collection of triangles and/or quadrangles determined by the product operation. Here we give an explicit construction for the lexicographic product G ◦ H that generalizes results by Berger and Jaradat to the case that H is not connected.

In this letter, we summarize initial results showing how solar cycle variations of the thermosphere modify the composition and intensity of ion upflows at high geomagnetic latitudes. Using an improved version of the one-dimensional hydrodynamic polar wind model developed by Gombosi et al. (1985), we obtain H + and O + vertical flow profiles using different thermospheric states corresponding to ...

In the random k-uniform hypergraph H (k) n,p of order n, each possible k-tuple appears independently with probability p. A loose Hamilton cycle is a cycle of order n in which every pair of consecutive edges intersects in a single vertex. It was shown by Frieze that if p ≥ c(log n)/n2 for some absolute constant c > 0, then a.a.s. H (3) n,p contains a loose Hamilton cycle, provided that n is divi...

Let H be a connected subgraph of graph G. An H-factor G is spanning whose components are isomorphic to H. Given set mutually non-isomorphic graphs, uniform H-factorization partition the edges into H-factors for some H∈H. In this article, we give complete solution existence problem H-factorizations Kn−I (the obtained by removing 1-factor from Kn) H={Ch,S(Ch)}, where Ch cycle length an even integ...

OBJECTIVE Major depression is associated to altered hypothalamic-pituitary function. Stress is linked to elevated cortisol as well as menstrual cycle disturbance; however, there is no known relationship between depression and menstrual cycle disruption. The aim of this study was to investigate changes of growth hormone (GH) secretion during the menstrual cycle in normal and depressed women. D...

Here, we prepared LiMn0.8Fe0.2PO4 microspheres with an open three-dimensional nanoporous structure by a facile ion-exchange solvothermal method. The micro/nano-structured material exhibits an ultralong cycle life, and retains a reversible capacity of 105 mA h g(-1) after 1000 cycles at 5 C, corresponding to the capacity retention of 94.0% and only 0.0068 mA h g(-1) loss per cycle.

BACKGROUND Anthracycline cardiotoxicity is increased by the contemporaneous administration of trastuzumab. The mechanism by which it occurs is as yet unknown. The aim of this study was to evaluate whether trastuzumab modifies the pharmacokinetics of epirubicin and its metabolites. PATIENTS AND METHODS Women with HER2-positive metastatic breast cancer were treated with epirubicin 75 mg/m(2) i....
