The Bicircular Problem (BCP) is a periodic time dependent perturbation of the Earth-Moon Restricted Three-Body that includes direct gravitational effect Sun. In this paper we use BCP to study existence Halo-like orbits around \(L_2\) in system taking into account By means computing families 2D invariant tori, show there are at least two different quasi-periodic \(L_2\).

Business Continuity Planning (BCP) is essential to the success and continued operation of organizations, it directly impacts business performance. Good BCP helps institutions prepare for unexpected disasters crises, enabling them continue operations in event such incidents. plays a critical role performance organizations. By establishing robust BCP, organizations can minimize disruptions, ensur...

BACKGROUND Although certain HBV mutations are known to affect the expression of Hepatitis e antigen, their association with HBV viral level or clinical outcomes is less clear. OBJECTIVES We evaluated associations between different mutations in the Basal Core promoter (BCP) and Pre-core (PC) regions of HBV genome and subsequent changes in HBV viral DNA level over seven years in a population of...

The pathogenesis of nonalcoholic steatohepatitis (NASH) is not fully understood, but many studies have suggested that oxidative stress plays a key role. The methionine- and choline-deficient diet (MCD) administration model can reproduce histopathological features of human NASH and is widely used for investigating NASH. C57BL/6J mice have been used in many studies, but strain differences in path...

The aim of this study was to evaluate the effect of porous biphasic calcium phosphate (BCP) scaffolds on the proliferation and osteoblastic differentiation of human periodontal ligament cells (hPDLCs) in the presence and absence of osteogenic inducer (L-ascorbic acid, dexamethasone and β-glycerophosphate). The cell growth within the scaffolds in the absence of osteogenic inducers was studied by...

BACKGROUND Current air quality standards for particulate matter (PM) use the PM mass concentration [PM with aerodynamic diameters ≤ 10 μm (PM(10)) or ≤ 2.5 μm (PM(2.5))] as a metric. It has been suggested that particles from combustion sources are more relevant to human health than are particles from other sources, but the impact of policies directed at reducing PM from combustion processes is ...

A photo-crosslinked polystyrene (PS) thin film is investigated as a potential guiding sub-layer for polystyrene-block-poly (methyl methacrylate) block copolymer (BCP) cylindrical nanopattern formation via topographic directed self-assembly (DSA). When compared to a non-crosslinked PS brush sub-layer, the photo-crosslinked PS sub-layer provided longer correlation lengths of the BCP nanostructure...

Boolean Constraint Propagation (BCP) is recognized as one of the most useful technique for efficient satisfiability checking. In this paper a new extension of the scope of boolean constraint propagation is proposed. It makes an original use of BCP to achieve further reduction of boolean formulas. Considering the implication graph generated by the constraint propagation process as a resolution t...

This paper proposes new algorithms for the Binate Covering Problem (BCP), a well-known restriction of Boolean Optimization. Binate Covering finds application in many areas of Computer Science and Engineering. In Artificial Intelligence, BCP can be used for computing minimum-size prime implicants of Boolean functions, of interest in Automated Reasoning and Non-Monotonic Reasoning. Binate Coverin...

The Cu(II)- and Co(II)-binding properties of two peptides, designed on the basis of the active site sequence and structure of the blue copper protein plastocyanin, are explored. Peptide BCP-A, Ac-Trp-(Gly)(3)-Ser-Tyr-Cys-Ser-Pro-His-Gln-Gly-Ala-Gly-Met-(Gly )(3)-His-(Gly)(2)-Lys-CONH(2), conserves the Cu-binding loop of plastocyanin containing three of the four copper ligands and has a flexible...
