In [L2], the author studied universal equations for genus-2 Gromov-Witten invariants given in [Ge1] and [BP] using quantum product on the big phase space. Among other results, the author proved that for manifolds with semisimple quantum cohomology, the genus-2 Gromov-Witten potential function F2 is uniquely determined by known genus-2 universal equations. Moreover, an explicit formula for F2 wa...

The Big Bang-Big Crunch (BB–BC) method is a relatively new meta-heuristic algorithm which inspired by one of the theories of the evolution of universe. In the BB–BC optimization algorithm, firstly random points are produced in the Big Bang phase then these points are shrunk to a single representative point via a center of mass or minimal cost approach in the Big Crunch phase. In this paper, the...

purpose: to assess parameters that had a capability of influencing the rate of big bubble formation during deep anterior lamellar keratoplasty (dalk) in keratoconus. methods: a total of 290 consecutive eyes from 257 patients with keratoconus that underwent dalk using the big-bubble technique were enrolled. the influence of patient age and sex, family history of keratoconus, history of contact l...

phytoplasmal big bud is one of the important diseases of tomato (lycopersicon esculentum) in the world. the disease has been reported from iranian provinces of bushehr, isfahan, fars, khorasane razavi and ardabil. during a summer surrvey in 2010, symptoms of big bud disease was observed in tomato fields of dorood area in lorestan province. characteristic symptoms of the disease were small thick...

BACKGROUND Atrial fibrillation (AF) is associated with inflammation and endothelial dysfunction. However, the association between inflammation (as indexed by high-sensitivity C-reactive protein, hs-CRP) and endothelial function [as indexed by big endothelin-1 (ET-1)] in AF patients remains unclear. METHODS We enrolled 128 patients with lone AF, among which 83 had paroxysmal AF, and 45 had per...

conclusions over-expression of the synthetic cpc/β protein in the bacterial system (escherichia coli bl-21) showed that e. coli can be used as a basis for further research to produce this desired protein in large quantities. results the sds-page analysis and dot blotting confirmed the production of recombinant c-pc/β in the bacterial expression system. over-expression of cpcb gene was optimized...

The paper presents an extension of the geometric quantization procedure to integrable, big-isotropic structures. We obtain a generalization of the cohomology integrality condition, we discuss geometric structures on the total space of the corresponding principal circle bundle and we extend the notion of a polarization. 1 Big-isotropic structures Weak-Hamiltonian functions belong to the framewor...

Context: Big Data Cybersecurity Analytics is increasingly becoming an important area of research and practice aimed at protecting networks, computers, and data from unauthorized access by analysing security event data using big data tools and technologies. Whilst a plethora of Big Data Cybersecurity Analytic Systems have been reported in the literature, there is a lack of a systematic and compr...
