Durian (Durio zibethinus Murr.) is one of tropic fruits that has varian taste depending on the places their production. Nias Island, well known as durian production place in North Sumatera. The information about it’s was less studied and now day we need to analyze variant especially Island. aim this research genetic diversity Island with Random Amplified Polymorphic DNA (RAPD). Ten shoots colle...

BACKGROUND Leisure time physical activity (LTPA) is generally associated with favorable cardiovascular health outcomes, while occupational physical activity (OPA) shows less clear, or even opposite, cardiovascular effects. This apparent paradox is not sufficiently understood, but differences in temporal patterns of OPA and LTPA have been suggested as one explanation. Our aim was to investigate ...

The efficient separation of ilmenite is a difficult problem in minerals flotation. For this issue, α-aminooctyl phosphinic acid (APA) was developed as selective collector to separate ilmenite. flotation test result showed that APA more for improving recovery compared with octylphosphonic (OPA). Adsorption, ZETA and FTIR measurements proved the chemical interaction between surface stronger than ...

A chip-level optical beam steerer is an inevitable choice for next-generation light detection and ranging (LiDAR). The research on phased array (OPA) the most intriguing. However, complexity of control calibration speed limit full potential as number channels increases. In this paper, improved stochastic parallel gradient-descent algorithm combined with Nesterov accelerated gradient method (NSP...

We propose a method to enhance bipartite and tripartite entanglement in cavity magnomechanics using an optical parametric amplifier (OPA). analyze this system identified regimes where different types of are enhanced. show that proper choice phase the leads enhancement entanglements. Moreover, is also significantly enhanced presence OPA. The OPA not only enhances strength but increases domain ov...

The notions of density, thinness, residue and ideal in a free monoid can all be expressed in terms of the infix order. Guided by these definitions we introduce the same notions with respect to arbitrary binary relations. We then investigate properties of these generalized notions and explore the connection to the theory of codes. We show that, under certain assumptions about the relation, densi...

There are more than 15 million college students in the US alone. Academic advising for courses and scholarships is typically performed by human advisors, bringing an immense managerial workload to faculty members, as well as other staff at universities. This paper reports and discusses the development of two educational expert systems at a private international university. The first expert syst...
