Known and unknown behaviors of three nonlinear systems are described in this paper. The power harvesting project is mentioned where the power generation mat using piezoelectric elements was experimented and demonstrated in Tokyo station of Japan Railways east (JR-east) company in 2006 and 2008 respectively. The commuters and passengers generate electric power by passing the power generation mat...

The purpose of this review is to characterize the preoperative assessment of meniscal allograft transplantation (MAT) candidates, to detail MAT surgical techniques, and to evaluate current clinical outcome data on MAT. The MAT candidate is typically less than 50 years old and has a history of knee injury, previous meniscus surgery, and persistent pain. Physical exam generally reveals knee pain ...

We read the article by Dutta et al on “Leptospirosis An Overview” with interest.1 The problem in utilizing microscopic agglutination test (MAT) has been highlighted and we shall discuss briefly the current status of MAT. MAT is considered the gold standard test for diagnosis of leptospirosis. It has unsurpassed specificity, but its sensitivity is low compared to ELISA/SAT (Slide agglutination t...

UNLABELLED Microbes can produce molecular hydrogen (H2) via fermentation, dinitrogen fixation, or direct photolysis, yet the H2 dynamics in cyanobacterial communities has only been explored in a few natural systems and mostly in the laboratory. In this study, we investigated the diel in situ H2 dynamics in a hot spring microbial mat, where various ecotypes of unicellular cyanobacteria (Synechoc...

This paper presents an algorithm for generating the Medial Axis Transform (MAT) of 3D objects with free form boundaries that are obtained by extrusion along a line or revolution about an axis. The algorithm proposed uses the exact representation of the part and generates an approximate rational spline description (to within a defined tolerance) of the MAT. The algorithm uses the 2D MAT of the p...

BACKGROUND Subsurface fluids from deep-sea hydrocarbon seeps undergo methane- and sulfur-cycling microbial transformations near the sediment surface. Hydrocarbon seep habitats are naturally patchy, with a mosaic of active seep sediments and non-seep sediments. Microbial community shifts and changing activity patterns on small spatial scales from seep to non-seep sediment remain to be examined i...

Let A be a well-formed formula of first-order modal logic whose only free variable is x. We shall use the following abbreviations: Mat(A) for (x)[OA * 0~A] Form(A) for (x)[DA vD-i] Ban(A) for ((x)DA) v ((x)U~A) Pred(A) for Form(A) v Mat(A). We read Mat(A), FormjA), and Ban(A) respectively as: "A is material", "A is formal", and "A is banal"; Pred(A) is the assertion of the Principle of Predica-...

We investigated the mechanism of nitric oxide (NO) action on hepatic methionine adenosyltransferase (MAT) activity using S-nitrosoglutathione (GSNO) as NO donor. Hepatic MAT plays an essential role in the metabolism of methionine, converting this amino acid into S-adenosylmethionine. Hepatic MAT exists in two oligomeric states: as a tetramer (MAT I) and as a dimer (MAT III) of the same subunit....

The Guerrero Negro (GN) hypersaline microbial mats have become one focus for biogeochemical studies of stratified ecosystems. The GN mats are found beneath several of a series of ponds of increasing salinity that make up a solar saltern fed from Pacific Ocean water pumped from the Laguna Ojo de Liebre near GN, Baja California Sur, Mexico. Molecular surveys of the laminated photosynthetic microb...
