The paper deals with mesh-connected massively parallel systems aaected by failures. The complexity of a local diagnostic procedure, based on new deenitions of the local k-diagnosability and the r-fault-tolerance, is analysed. It depends on distances between individual fault clusters and on fault cluster diameters. In particular cases the minimum distance between fault clusters can be enlarged o...

Directed hypergraphs are used to model networks whose nodes are connected by directed buses. We study in this paper two parameters related to the fault-tolerance of directed bus networks: the connectivity and the fault-diameter of directed hypergraphs. Some bounds are given for those parameters. As a consequence, we obtain that de Bruijn-Kautz directed hypergraphs and, more generally, iterated ...

Abstract Purpose To examine the association of maternal bone markers [sclerostin, soluble receptor activator nuclear factor-?B ligand (sRANKL), osteocalcin, 25-hydroxyvitamin D3] with fetal intra-abdominal and subcutaneous adipose tissue deposition birthweight during normal pregnancy. Methods One hundred pregnant women (aged 30.4 ± 5.6 years, mean SD) prepregnancy body mass index = 24.1 4.6 kg/...

Drought has a serious impact on agriculture worldwide. A plant's ability to adapt to rhizosphere drought stress requires reprogramming of root growth and development. Although physiological studies have documented the root adaption for tolerance to the drought stress, underlying molecular mechanisms is still incomplete, which is essential for crop engineering. Here, we identified OsNAC6-mediate...

In 1978, Chvátal and Thomassen proved that every 2-edge-connected graph with diameter 2 has an orientation with diameter at most 6. They also gave general bounds on the smallest value f(d) such that every 2-edge-connected graph G with diameter d has an orientation with diameter at most f(d). For d = 3, their general bounds reduce to 8 ≤ f(3) ≤ 24. We improve these bounds to 9 ≤ f(3) ≤ 11.

Abstract It is important to evaluate nitrogen use efficiency and tolerance of trees in order improve their productivity. In this study, both were evaluated for 338 Populus deltoides genotypes from six provenances. The plants cultured under normal (750 μM NH 4 NO 3 ) low (5 conditions months. Growth, chlorophyll content glutamine synthetase activity each genotype measured. Under nitrogen, height...

An interconnection network should be fault tolerant, because practical communication networks are exposed to failures of network components. Both failures of nodes and failures of connections between them happen and it is desirable that a network is robust in the sense that a limited number of failures does not break down the whole system. A lot of work has been done on various aspects of netwo...

A fundamental challenge in data centers is how to design distinguished networking topology for efficiently interconnecting a large number of servers. This paper studies the design of Data Center Networking (DCN) from the aspect of the degree/diameter problem, which determines desirable DCNs that support the largest number of servers given maximum server degree and given diameter. More specifica...

We present a new approach for producing elastomeric optical fibers with an behaviour corresponding to few-mode fiber. Different have been produced by first fabricating thermoplastic polyurethane preforms and subsequently drawing them. The fiber attenuation has measured the cut-back technique bending transmission tolerance evaluated. potential assessed through two basic experiments in order high...
