This review summarizes the models that researchers use to represent the conformations and dynamics of cytoskeletal and DNA filaments. It focuses on models that address individual filaments in continuous space. Conformation models include the freely jointed, Gaussian, angle-biased chain (ABC), and wormlike chain (WLC) models, of which the first three bend at discrete joints and the last bends co...

OBJECTIVES To assess the additional detection rate (ADR) of within-patient comparisons of Narrow band imaging (NBI) and white light cystoscopy (WLC) for non-muscle invasive bladder cancer (NMIBC) detection and compare the impact of NBI and WLC on bladder cancer recurrence risk. METHODS We searched relevant studies from PubMed, Embase, Medline, Web of Science and the Cochrane Library database ...

Today, we o perate in a networked world, where organizations frequently resort to offshoring, such that work gets accomplished by a globally distributed workforce, whether inside or outside the organizational boundaries. Much of the past research on offshoring has focused on economic rationale and benefits as well as risks associated with offshoring. Offshoring leverages human capital in differ...

OBJECTIVE To evaluate the efficacy of narrow band imaging (NBI) cystoscopy associated with bipolar plasma vaporization (BPV) in cases of large nonmuscle-invasive bladder tumors (NMIBTs) compared with white light cystoscopy (WLC) and monopolar transurethral resection of bladder tumors (TURBTs). METHODS A total of 220 cases with ≥ 1 bladder tumor >3 cm determined by abdominal ultrasonography, c...

We introduce a biologically motivated dynamical principle of sequential memory which is based on winnerless competition (WLC) of event images. This mechanism is implemented in a two-layer neural model of sequential spatial memory. We present the learning dynamics which leads to the formation of a WLC network. After learning, the system is capable of associative retrieval of prerecorded sequence...
