SmB6, a well-known Kondo insulator, exhibits a transport anomaly at low temperature. This anomaly is usually attributed to states within the hybridization gap. Recent theoretical work and transport measurements suggest that these in-gap states could be ascribed to topological surface states, which would make SmB6 the first realization of topological Kondo(More)
C-repeat/dehydration-responsive element binding factor (CBF) plays important roles in cold response network in plants. Here, one member of CBF coding gene family in trifoliate orange (Poncirus trifoliata), designated as PtCBF, was isolated. Semi-quantitative reverse transcription-polymerase chain reactions showed up-regulation of PtCBF not only under low(More)
Mining frequent subgraphs is a basic activity that plays an important role in mining graph data. In this paper an algorithm is proposed to find frequent subgraphs in a single large graph that has applications such as protein interactions, social networks, web interactions. One of the key operations required by any frequent subgraph discovery algorithm is to(More)
A biometric system which uses a single trait is unable to meet the required security levels. Authentication based on multi-biometrics is an emerging trend these days. This paper deals with the biometric authentication system which integrates face and voice biometrics. The system requests the user for an audio sample and an image of his face. The fusion of(More)
Iris recognition is most precise and consistent biometric identification system accessible in the current situation. The demand for an accurate biometric system that provides dependable identification and verification of an individual has increased over the years. A biometric system that provides reliable and accurate identification of an individual is an(More)
In this paper, a new hybrid conjugate gradient method is proposed for solving unconstrained optimization problems. The parameter β k is computed as a convex combination of β F R k and β * k algorithms, i.e. β N k = (1 − θ k)β F R k + θ k β * k. The parameter θ k is computed in such a way so that the direction corresponding to the conjugate gradient(More)
