We have demonstrated that tubulin-GTP subunits can react with microtubule ends containing subunits with E-site-bound GDP. This observation can be taken to rule out a previous interpretation of a biphasic dependence of the rate for subunit flux into microtubules on the subunit concentration, which is based upon an assumption that GTP is required to be present in subunits at microtubule ends in o...

Manipulation is an important issue for both developed and emerging stock markets. Many efforts have been made to detect manipulation in stock markets. However, it is still an open problem to identify the fraudulent traders, especially when they collude with each other. In this paper, we focus on the problem of identifying the anomalous traders using the transaction data of eight manipulated sto...

We have measured low field dc and low frequency ac magnetic properties of high quality magnetite single crystals with continuously reading high resolution SQUID magnetometer in a temperature range of 5 – 150 K. In these data several features can be observed: the anisotropy point around 130 K, Verwey transition near 122 K, glass-like transition around 40 K and finally anomalous magnetic behaviou...

The thermodynamics of a disordered planar vortex array is studied numerically using a new polynomial algorithm which circumvents slow glassy dynamics. Close to the glass transition, the anomalous vortex displacement is found to agree well with the prediction of the renormalization-group theory. Interesting behaviors such as the universal statistics of magnetic susceptibility variations are obse...

this paper investigated the effects of combining fibers with self-consolidating concrete (scc). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (pps) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. all plans were subjected to fresh concrete tests. for mechanical behavior of...

In order to protect vital data in today’s internet environment and prevent misuse, especially insider abuse by valid users, we propose a novel two-step detecting approach to distinguish potential misuse behaviour (namely anomalous user behaviour) from normal behaviour. First, we capture the access patterns of users by using association rules. Then, based on the patterns and users’ sequential be...

The iron-based oxypnictide superconductor SmFeAsO0.8F0.2 was synthesized under high-pressure and investigated by measuring dc magnetic susceptibility. zero-field cooled (ZFC) susceptibility confirmed the bulk superconductivity of sample with a critical temperature Tc = 50 K significant jump in magnetization at 4.3 K, usually attributed to antiferromagnetic ordering Sm3+ ions this system. Since ...

We present a self-consistent calculation of anomalous second-harmonic generation in glass optical fibers. Quantum interference between multiphoton absorption processes leads to asymmetric photoelectric emission from defects, creating a spatially periodic space-charge electric field. The second harmonic is found to grow exponentially along the fiber, then saturate to a maximum value proportional...
