We investigate 3D Yang-Mills theory coupled to an adjoint scalar, which can be regarded as a zeroth order approximation in (de)constructing 4D Yang-Mills theory. We develop a new algorithm to obtain the renormalized Hamiltonian with the Karabali-Nair

A series of 4-amino-5-chloro-2-methoxy-N-(piperidin-4-ylmethyl)benzamides with a polar substituent group at the 1-position of the piperidine ring was synthesized and evaluated for its effect on gastrointestinal motility. The benzoyl, phenylsulfonyl,

Rho-associated coiled-coil-forming protein kinase (ROCK) is pivotally involved in invasion by tumor cells and their evolution to metastasis. We have developed a novel inhibitor of ROCK, Wf-536 [(+)-(R)-4-(1-aminoethyl)-N-(4-pyridyl) benzamide monohyd

This paper describes a method of predicting the degradation in safety and determining the optimum time and degree of strengthening for existing concrete bridges. Degradation in safety is predicted by using a degradation curve based on material tests

The probability of the presence of stacking faults in the β-form single crystals of syndiotactic polystyrene, which were grown isothermally from a dilute solution at a temperature ranging from 150 to 210 °C, was estimated from the mean half-breadth

Isotactic polypropylene (iPP) was crystallized from solution on a uniaxially-oriented iPP film. Small-angle x-ray scattering patterns obtained from the sample showed two perpendicularly crossed lameliae 9.3 nm thick that overgrew flat-on and edge-on
