The coupled lateral–torsional stochastic response of an asymmetric one-storey base isolated building to earthquake excitation is presented. The stochastic model of the 1940 El-Centro earthquake, which preserves the non-stationary evolution of the amplitude and frequency content of the ground acceleration, is used as earthquake excitation. The base isolator consists of an array of elastomeric be...

Introduction Otosclerosis is a disease that causes bone resorption and deposition in the auditory structures, leading to deafness. Many studies have evaluated the histopathology of the stapes footplate in this disease (osteoblasts, osteoclasts, vascular proliferation, fibroblasts, and histiocytes), but we found no studies in the literature involving the histology of the superstructure of the st...

Order-disorder-order phase transitions in the clathrate-I Ba8Cu16P30 were induced and controlled by aliovalent substitutions of Zn into the framework. Unaltered Ba8Cu16P30 crystallizes in an ordered orthorhombic (Pbcn) clathrate-I superstructure that maintains complete segregation of metal and phosphorus atoms over 23 different crystallographic positions in the clathrate framework. The driving ...

At present, box-girder superstructures are commonly used in coastal bridges, and their hydrodynamic performance under extreme waves such as tsunamis has attracted a lot of attention. There is lack research focusing on the effect lateral restraining stiffness wave condition. In this paper, two-dimensional numerical model based RANS equation SST k-? turbulence established. Combined with dynamic m...

The new design of the accelerating structures for TESLA, the so-called superstructures composed out of several multicell cavities, is studied. Here a superstructure is composed out of four seven-cell superconducting resonators, e.g. in total 28 coupled cells. A central question is the filling characteristic of the superstructure since each is fed by one coupler only. The filling and the beam lo...

Rotating packed bed (RPB), a novel apparatus involving process intensification (PI), has been successfully used in the chemical industry in recent decades. In this paper, we establish a connection between process integration and process intensification for which we propose a superstructure involving a RPB and a packed bed (PB) in order to determine the optimal integrated design. We describe mod...

We report here a fast-photon-mode reversible handedness inversion of a self-organized helical superstructure (i.e., a cholesteric liquid crystal phase) using photoisomerizable chiral cyclic dopants. The two light-driven cyclic azobenzenophanes with axial chirality show photochemically reversible trans to cis isomerization in solution without undergoing thermal or photoinduced racemization. As c...

Any modern approach to a Marxist theory of culture must begin by considering the proposition of a determining base and a determined superstructure. From a strictly theoretical point of view this is not, in fact, where we might choose to begin.1 It would be in many ways preferable if we could begin from a proposition which originally was equally central, equally authentic: namely the proposition...

This paper presents a nonlinearly parameterized controller for the adaptive control of base-isolated buildings subjected to a set of near-fault earthquakes. The control scheme is based on discrete direct adaptive control, wherein the system response is minimized under parameter uncertainties. Stable tuning laws for the controller parameters are derived using the Lyapunov approach. The controlle...

Disordered and uniform (2√3 × 2√3)R30° superstructures of fullerenes on the Au(111) surface have been studied using scanning tunneling microscopy and spectroscopy. It is shown that the deposition and growth process of a fullerene monolayer on the Au(111) surface determine the resulting superstructure. The supply of thermal energy is of importance for the activation of a Au vacancy forming proce...
