We show that the standard perfect fluid paradigm is not necessarily a valid description of a curved space steady state gravitational source. Simply by virtue of not being flat, curved space geometries have to possess intrinsic length scales, and such length scales can affect the fluid structure. For modes of wavelength of order or greater than such scales eikonalized geometrical optics cannot a...

A computational study was previously carried out to analyze DNA sequences that are known to position histone octamers at single translational sites. A conserved pattern of intrinsic DNA curvature was uncovered that was proposed to direct the formation of nucleosomes to unique positions. The pattern consists of two regions of curved DNA separated by preferred lengths of non-curved DNA. In the pr...

Abstract: The vibration analysis of horizontally curved beams is generally led to higher order shape functions using direct finite element method, resulting in more time-consuming computation process. In this paper, the weak-form mixed finite element method was used to reduce the order of shape functions. The shape functions were first considered linear which did not provide adequate accuracy....

Systems of particles interacting through a screened Coulomb potential of the Debye-Yukawa form are considered. The pressure is obtained from the stress tensor of the field corresponding to the Yukawa interaction, by a suitable statistical average. This approach is especially appropriate for systems living in a curved space. In a curved space, a self contribution to the pressure appears, and it ...

In this paper we discuss our work on plan management in the Autominder cognitive orthotic system. Autominder is being designed as part of an initiative on the development of robotic assistants for the elderly. Autominder stores and updates user plans, tracks their execution via input from robot sensors, and provides carefully chosen and timed reminders of the activities to be performed. It will...

This paper describes a novel encoding for sequential numeric planning into the problem of determining the satisfiability of a logical theory T . We introduce a novel technique, orthogonal to existing work aiming at producing more succinct encodings that enables the theory solver to roll up an unbounded yet finite number of instances of an action into a single plan step, greatly reducing the hor...

In this paper, we present an explicit form of highorder mixed Rao–Wilton–Glisson basis functions for electromagnetic (EM) simulation of curved conductor surfaces. Basis functions for combinations of curved triangular and quadrilateral patches can be used. Several applications of EM simulations in multilayered media, such as three-dimensional discontinuities in very large scale integration desig...
