abstract r. ficaria is an invasive perennial and tuberous roots weed. the most important means of its reproduction and dispersion are tubers. in order to study the effect of droughty and freezing on germination of lesser celandine tubers, two experiments were conducted at weed science laboratory of faculty of agriculture ferdowsi university of mashhad in 2008. the experiment was a completely ra...

A B S T R A C T This survey presents the concept of Big Data. Firstly, a definition and the features of Big Data are given. Secondly, the different steps for Big Data data processing and the main problems encountered in big data management are described. Next, a general overview of an architecture for handling it is depicted. Then, the problem of merging Big Data architecture in an already exis...

Thus, f is big O of g if f is bounded above by a constant multiple of g. Intuitively, f(n) = O(g(n)) means that f grows no faster than g as the index n grows. For example, the function f(n) = n2 is big O of the function g(n) = n3, while it is not true that g is big O of f in this case. Every function is big O of itself. The requirement that the inequality in the above definition of big O hold f...

Until recently, Clostridium difficile phages were limited to Myoviruses and Siphoviruses of medium genome length (32-57 kb). Here we report the finding of phiCD5763, a Siphovirus with a large extrachromosomal circular genome (132.5 kb, 172 ORFs) and a large capsid (205.6 ± 25.6 nm in diameter) infecting MLST Clade 1 strains of C. difficile. Two subgroups of big phage genomes similar to phiCD576...

This editorial paper provides an overview of the Buildings Special Issue (SI), dedicated to topic “Applications (Big) Data Analysis in A/E/C” (where A/E/C stands for architecture, engineering, and construction) academic papers it includes [...]

We consider the inverse mean curvature flow in RobertsonWalker spacetimes that satisfy the Einstein equations and have a big crunch singularity and prove that under natural conditions the rescaled inverse mean curvature flow provides a smooth transition from big crunch to big bang. We also construct an example showing that in general the transition flow is only of class C.

in this paper a discrete big bang-big crunch algorithm is applied to optimal design of reinforced concrete planar frames under the gravity and lateral loads. optimization is based on aci 318-08 code. columns are assumed to resist axial loads and bending moments, while beams resist only bending moments. second-order effects are also considered for the compression members, and columns are checked...
