Integer overflow is a common vulnerability in Ethereum Smart Contracts (ESCs) and often causes huge economic losses. contracts cannot be changed once it deployed on the blockchain thus demand further testing. Mutation testing fault-based method that can effectively improve sufficiency of test for smart contracts. However, existing methods efficiently perform mutation specifically integer ESCs. ...

Embryonic stem cells (ESCs) are originally derived from the ICM of blastocysts and are characterized by their ability to self-renew and their pluripotencies. Only a few reports have been published on ESC isolations and line establishment in animals, even fewer in horses. However, it is still important to isolate equine ESCs for animal biotechnology and therapeutic applications. In the present s...

objective: nuclear transfer-embryonic stem cells (nt-escs) are genetically identical to the donor’s cells; provide a renewable source of tissue for replacement, and therefore, decrease the risk of immune rejection. trichostatin a (tsa) as a histone deacetylase inhibitor (hdaci) plays an important role in the reorganization of the genome and epigenetic changes. in this study, we examined whether...

La finalidad de este estudio fue someter a prueba cuatro modelos jerárquicos multinivel para explicar el logro en matemáticas alumnos mexicanos la PISA 2012. Se incluyeron como predictores ocho variables Oportunidades Aprendizaje (OTL) (tres índices Prácticas enseñanza y cinco Calidad enseñanza), control: Sostenimiento escuela, Nivel escolar, Índice estatus social, económico cultural (ESCS) Pro...

embryonic stem cells (escs) are derived from the inner cell mass (icm) of blastocyst and differentiate into all three embryonic germ layers: ectoderm, endoderm, and mesoderm. in this study, escs are derived from hand made cloning (hmg) blastocysts and their efficiencies compared to escs derived from in vitro fertilization (ivf) embryos. feeder layer was used for escs culture, and culture medium...

Objective Genetic and morphologic similarities between mouse embryonic stem cell (ESCs) and Primordial Germ Cell (PGCs) make it difficult to distinguish the two cell types in in vitro differentiation. Using the expression of specific markers of germ cells that are not expressed or expressed at low levels in ESCs, can help recognizing in vitro differentiated cells MaterialsAndMethods In this stu...

High-energy incoming photons can be absorbed and concluded to generate Hot Carriers. In normal solar cells, these carriers are scattered by electron–electron electron-lattice mechanisms rapidly lose extra energy approach conduction band edge. This event plus other loss cause that the efficiency of cells limited 33% theoretically. If one makes possibility for extracted rapidly, before scattering...

Abstract Despite its widespread trajectory and global presence, studies on Economic Social Councils (ESCs) are not frequent. Thus, this study aims to review the existing scientific literature institution identify main thematic nuclei, agreements, discrepancies, detect research gaps outline future lines. Based application of PRISMA Protocol, three emerging nuclei ESCs have been detected: factors...
