By extending the approach of Berry and Robnik, the limiting level spacing distribution of a system consisting of infinitely many independent components is investigated. The limiting level spacing distribution is characterized by a single monotonically increasing function mu(S) of the level spacing S. Three cases are distinguished: (1) Poissonian if mu(+ infinity)=0, (2) Poissonian for large S, ...

BACKGROUND The distribution of birth intervals can be used to draw attention to important characteristics of dynamics of fertility process. The main objective of this paper is to examine the effects of socioeconomic, demographic and proximate determinants on the length of birth intervals of women of Bangladesh and also to see whether the effects are changed over the years. METHODS Birth inter...

Block volumes are generally estimated by analyzing the discontinuity spacing measurements obtained either from the scan lines placed over the rock exposures or the borehole cores. Discontinuity spacing measurements made at the Mesozoic limestone quarries in Karaburun Peninsula were used to estimate the average block volumes that could be produced from them using the suggested methods in the lit...

We present a unified analysis of finite element methods for problems with prescribed moving boundaries. In particular, we study an abstract parabolic problem posed on a moving domain with prescribed evolution, discretized in space with a finite element space that is associated with a moving mesh that conforms to the domain at all times. The moving mesh is assumed to evolve smoothly in time, exc...

The spacing effect describes the robust phenomenon whereby memory is enhanced when learning events are distributed, instead of being presented in succession. We investigated the effect of spacing on children's memory and category induction. Three-year-old children were presented with two tasks, a memory task and a category induction task. In the memory task, identical instances of an object wer...

For an inductive power transfer system, high quality factor means that the system can obtain large theoretical transmission efficiency. In this paper, a method of coil optimization in limited space to improve for series-series compensated is presented. High be achieved by determining optimal number turns with equal turn spacing coil, and then optimizing distance between adjacent turn. The resul...

Two main difficulties for the accurate direction of arrival (DOA) estimation in a distributed sensor system are grating lobes and synchronization. Different from traditional phased array based on single carrier frequency, this paper designs novel architecture using dual frequency measurements. Both two frequencies combined transmitted simultaneously proposed architecture. Instead f1 method, sep...

The proper orientation and lateral spacing of antibody molecules are a crucial element for an on-chip immunoassay in which the antibody or its antigen-binding fragments are immobilized on a solid surface. We covalently immobilized a modified protein G (Cys-protein G: protein G with only an N-terminal cysteine) on a dendron-coated surface to control its orientation and lateral spacing simultaneo...

Combinatorial transcription factor (TF) binding is essential for cell-type-specific gene regulation. However, much remains to be learned about the mechanisms of TF interactions, including to what extent constrained spacing and orientation of interacting TFs are critical for regulatory element activity. To examine the relative prevalence of the 'enhanceosome' versus the 'TF collective' model of ...
