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 teaching a foreign language (fl), some cultural specificities (defined under the rubric of ‘little-c culture’) may totally conflict with the cultural norms of the learners’ first language (l1). to prevent such imminent problems, this paper recommended that the fl syllabus be designed in a way so as to equip learners with an intimate knowledge of the target language culture, and that language...

Rural ethnic cultural archives have great potential in serving rural revitalization. Big data technology improves the application ability of big by improving “processing ability”, and constructs a “big + management” mechanism, which can give more convenient play to value archives. Starting from problems existing construction informatization talents digitization system, this paper puts forward i...
