Nucleosome positioning is an important process required for proper genome packing and its accessibility to execute the genetic program in a cell-specific, timely manner. In the recent years hundreds of papers have been devoted to the bioinformatics, physics and biology of nucleosome positioning. The purpose of this review is to cover a practical aspect of this field, namely, to provide a guide ...

Transcription factors canonically bind nucleosome-free DNA, making the positioning of nucleosomes within regulatory regions crucial to the regulation of gene expression. Using the assay of transposase accessible chromatin (ATAC-seq), we observe a highly structured pattern of DNA fragment lengths and positions around nucleosomes in Saccharomyces cerevisiae, and use this distinctive two-dimension...

Applications of vision-based remotely operated robotic systems range from planetary exploration to hazardous waste remediation. For space applications, where communication time lags are large, the target selection and robot positioning tasks may be performed sequentially, differing from conventional telerobotic maneuvers. For these point-and-move systems, the desired target must be defined in t...

Context-aware computing is an emerging computing paradigm that can provide new or improved services by exploiting user context information. In this paper, we present a wireless-localarea-network-based (WLAN-based) indoor positioning technology. The wireless device deploys a positiondetermination model to gather location information from collected WLAN signals. A model-based signal distribution ...

The past decade has witnessed substantial research on methods for indoor Wi-Fi positioning. While much effort has gone into achieving high positioning accuracy and easing fingerprint collection, it is our contention that the general problem is not sufficiently well understood, thus preventing deployments and their usage by applications to become more widespread. Based on our own and published e...

The size and shape of the treatment fields applied in radiotherapy account for uncertainties in the daily set-up of the patients during the treatment. We investigated the accuracy of daily patient positioning in the bellyboard pelvic radiotherapy in order to find out the magnitude of the patients movement during the treatment. Translational as well as rotational movements of the patients are ex...

Consumers have been spoiled by the quality of Halal products available on the market. However, existing literature has lacked recognition for consumer Halal cosmetic products. Therefore, this study enhances the body of knowledge about consumer attitude and intention to purchase Halal cosmetic products. Specifically, this article will discuss the moderating effect positioning has on attitude wit...

concerning the population growth and urban development, significant growth in the rate of personal car usage has caused more transportation and thus growth in occupying the street areas for parking vehicles. this has caused much transporting problems and traffic. hence concerning the parking issue is crucial in traffic and municipal management.the important issue is the suitable place for the p...

Extended Kalman Filter (EKF) algorithm is widely used in GPS positioning and velocity measurement. As for EKF algorithm, the approximate initial position of the receiver is indispensable; otherwise the time consumption of the first positioning is too high because of the filter’s low convergence rate. A modified EKF algorithm named delayed update EKF (DU-EKF) algorithm for GPS point dynamic posi...

This paper estimates the effect of presentation of information on financial markets, using a natural experiment in prominent “front page” positioning of news on the Bloomberg terminal. The front page and non-front page articles are indistinguishable by either algorithmic analysis or by the target audience of active finance professionals. Front page positioning induces 280% higher trading volume...
