Underground pipelines are widely applied in the so-called lifeline engineerings. It shows according to seismic surveys that the damage from soil liquefaction to underground pipelines was the most serious, whose failures were mainly in the form of pipeline uplifting. In the present study, dynamic centrifuge model tests were conducted to study the uplifting behaviors of shallow-buried pipeline su...

George D. Ricco is a doctoral student in Purdue University's School of Engineering Education. He previously received an M.S. in earth and planetary sciences studying geospatial imaging and a M.S. in physics studying high-pressure, high-temperature FT-IR spectroscopy in heavy water, both from the University of California, Santa Cruz. He has a B.S.E. in engineering physics with a concentration in...

It is important to provide a representation method of gene regulatory networks which realizes the intuitions of biologists while keeping the universality in its computational ability. In this paper, we propose a method to exploit hybrid Petri net (HPN) for representing gene regulatory networks. The HPN is an extension of Petri nets which have been used to represent many kinds of systems includi...

Lime system has a chemical composition CaO, which is known as thermodynamically stable. The purpose here is to explore further possible phases under pressure, by means of variable-composition ab initio evolutionary algorithm. The present investigation shows surprisingly new stable compounds of lime. At ambient pressure we predict, in addition to CaO, CaO2 as new thermodynamically stable compoun...

One of key factors affecting the effective application of tissue engineering is the development of scaffolds, which provide the physical support for adhesion and expansion of cells that can regenerate the lost of diseased tissue. Recently, several scaffolds consisting of synthetic materials or substance derived from natural tissue, such as poly(lactic acid) (PLA) (1), poly(glycolic acid) (PGA) ...

Calphad description at high pressure is a very important topic. Several models have been proposed in the literature. The model by Lu et al. (X.-G. Lu, M. Selleby and B. Sundman, Comput. Coupling Phase Diagr. Thermochem., 29 (2005) 49-55) convenient many aspects. But it has criticized for giving unphysical extrapolations certain conditions. We show that this indeed suitable if additional constra...

Advances in materials science and engineering have played a central role the development of classical computers will undoubtedly be critical propelling maturation quantum information technologies. In approaches to computation based on superconducting circuits, as one goes from bulk functional devices, amorphous films non-equilibrium excitations — electronic phononic are introduced, leading diss...
