Molecular dynamics (MD) simulations offer a way to explore the conformational state space of large, biologically relevant molecules. Our sampling method, called “concurrent adaptive sampling” (CAS), utilizes MD simulations by letting a number of “walkers” adaptively explore the state space in consecutive steps. Walkers start in one conformational state, execute a short MD simulation and thus en...

In this paper, we propose two efficient statistical sampling techniques for estimating the total power consumption of large hierarchical circuits. We first show that, due to the characteristic of sampling efficiency in Monte Carlo simulation, granularity of samples is an important issue in achieving high overall efficiency. The proposed techniques perform sampling both temporally (across differ...

Medical and social sciences demand sampling techniques which are robust, reliable, replicable and give samples with the least bias. Majority of the applications of sampling use randomized sampling, albeit with stratification where applicable to lower the bias. The randomized technique is not consistent, and may provide different samples each time, and the different samples themselves may not be...

A novel technique for sampling clock recovery in a wideband networking waveform of a software defined radio is proposed. Sampling clock recovery is very important in wideband networking radio operation as it directly affects the Medium Access adaptive time slot switching rate. The proposed Sampling clock recovery algorithm consists of three stages. In the first stage, Sampling Clock Offset (SCO...

Among the three major components of a closed birth interval, waiting time to conception can somehow be managed with effective contraceptives while gestation is universally constant in its duration; the duration of postpartum amenorrhoea (PPA) varies in complex nature. The present study aimed to investigate the proximate factors influencing the duration of PPA. A community-based, cross-sectional...

BACKGROUND Low bone mineral density (BMD) is a public health issue in Saudi Arabia. This study measured the prevalence and factors associated with low BMD in Saudi women in Riyadh, Saudi Arabia. METHODS A cross sectional study using two stage cluster sampling technique was conducted in Riyadh, 2009. Thirty clusters, each comprising of 300 houses were randomly chosen and from each cluster 38-4...

Low- and middle-income countries have a higher burden of fatal and non-fatal injuries. The lack of evidence-based information hampers efforts for injury prevention. The aim of this study was to calculate non-fatal injury incidence rates and to investigate causes and risk factors for non-fatal injuries in Khartoum state. Information was gathered in a community-based survey using a stratified two...

Multi-processor system-on-chip (MPSoC) simulators are many orders of magnitude slower than the hardware they simulate due to increasing architectural complexity. In this paper, we propose a new application sampling technique to accelerate the simulation of MPSoC design space exploration (DSE). The proposed technique dynamically combines simultaneously executed phases, thus generating a sampling...
