We consider a continuous-time optimization method based on dynamical system, where massive particle starting at rest moves in the conservative force field generated by objective function, without any kind of friction. formulate restart criterion mean dissipation kinetic energy, and we prove global convergence result for strongly-convex functions. Using Symplectic Euler discretization scheme, ob...

According to data in the literature, the adaptive mechanisms occuring in the surgically aquired single kidney (SK) compared to those occurring in the congenital single kidney, seem to be compl...

In order to argue effectively one must have a grasp of both the normative strength of the inferences that come into play and the effect that the proposed inferences will have on the audience. In this paper we describe a program, NAG (Nice Argument Generator), that attempts to generate arguments that are both persuasive and correct. To do so NAG incorporates two models: a normative model, for ju...

The possible production of a heat-stable enterotoxin (Vc-H-ST) by Vibrio cholerae non-O1 serogroup Hakata was investigated, and the purified Vc-H-ST was characterized. It has a unique amino acid sequence, LIDCCEICCNPACFGCLN. This sequence is quite similar to that of the heat-stable enterotoxin (NAG-ST) produced by V. cholerae non-O1 except for one amino acid (leucine) residue excess at the N te...

During crystallization screenings of commercially available hydrolytic enzymes, the new, hexagonal crystal form of CAL-B, has been discovered and hereby reported. The NAG molecules, which were closing the glycosylation site in the orthorhombic form, in hexagonal structure make the glycosylation site open. It is unknown whether the opening and closing of the glycosylation site by the 'lid' NAG m...

We introduce a minimal stochastic lattice model for the column relative humidity (R) in tropics, which incorporates convective moistening, horizontal transport and subsidence drying. The probability of convection occurring location increases with R, based on Tropical Rainfall Measuring Mission observations, providing positive feedback that could lead to aggregation. show simple reproduces many ...

It is not clear if panic disorder (PD) and agoraphobia are variants of the same disorder or distinct diseases. A laboratory test could help resolve this issue. Research has shown that levels of the urinary lysosomal enzyme N-acetyl-beta-glusosaminidase (NAG) differ between patients with various psychiatric disorders. This study examined whether NAG levels would be similar in PD and agoraphobia,...

Microbial colonization and biofilm formation on the surface of implant devices may cause peri-implantitis and lead to bone loss. The aim of this study was to develop a novel antibacterial titanium implant surface and to test its biological performance. In a previous study, we demonstrated that titanium plates deposited by nanosilver acquired antibacterial activity to Staphylococcus aureus and E...

A novel chitin-degrading aerobe, Chitinibacter tainanensis, was isolated from a soil sample from southern Taiwan, and was proved to produce N-acetyl glucosamine (NAG). Chitin degrading factors (CDFs) were proposed to be the critical factors to degrade chitin in this work. When C. tainanensis was incubated with chitin, CDFs were induced and chitin was converted to NAG. CDFs were found to be loca...
