Age classification based on computer vision has widespread applications. Most of previous works only utilize texture feature or use contour and texture feature separately. In this paper, we proposed an age classification system that integrate contour and texture information. Besides, we improve the traditional Local Binary Pattern(LBP) feature extraction method and get pure texture feature. Sup...

Distributed systems designed to serve clients across the world often make use of geo-replication to attain low latency and high availability. Conflict-free Replicated Data Types (CRDTs) allow the design of predictable multi-master replication and support eventual consistency of replicas that are allowed to transiently diverge. CRDTs come in two flavors: state-based, where a state is changed loc...

The enantiospecific desorption kinetics of R- and S-propylene oxide (PO) from a Cu(100) surface modified by enantiomerically pure D- or L-lysine have been studied using temperature programmed desorption. These experiments have used R- or S-PO as the chiral probe for study of enantiospecific adsorption on Cu(100) surfaces modified with D- or L-lysine. This chiral probe/modifier/Cu system manifes...

This article looks into the concept of Buddha-nature in Maṇi bka’ ’bum, a revealed text (gter ma) ascribed to ancient Tibetan king Srong bstan sgam po, who is considered an incarnation Bodhisattva Avalokiteśvara, tutelary deity Tibet. There are two main technical terms that designate this text. One well-known bde bar gshegs pa’i snying used express idea all sentient beings have Buddha-nature, w...

Microbial degradation of the chiral 2-phenylbutyric acid (2-PBA), a metabolite of surfactant linear alkylbenzene sulfonates (LAS), was investigated using both racemic and enantiomer-pure compounds together with quantitative stereoselective analyses. A pure culture of bacteria, identified as Xanthobacter flavus strain PA1 isolated from the mangrove sediment of Hong Kong Mai Po Nature Reserve, wa...

In addition to the previously studied Zn(2+), low concentrations (about 0.5 mM) of Be(2+), Ba(2+), Cd(2+), Ni(2+), Cu(2+), Pt(4+) and, outstandingly, 0.5 microM of UO(2) (2+), potentiate the twitch of frog sartorius and toe muscles by prolonging the active state of contraction. The degree of potentiation is a roughly S-shaped function of p(metal(2+)), suggesting that each metal binds to a ligan...
