Colorectal cancer is among the most lethal of malignancies, due to its propensity to metastatic spread and multifactorial-chemoresistance. The latter property supports the need to identify novel therapeutic approaches for the treatment of colorectal cancer. MicroRNAs are endogenous non-coding small RNA molecules that function as post-transcriptional regulators of gene expression. Recently, prog...

Using a simple model with bimodal dynamics, we investigate the intra- and inter-system entrainment of the two different time scales involved in the chaotic oscillations. The transition between mode-locked and mode-unlocked chaos is analyzed for a single system. For coupled oscillators, we demonstrate full and partial synchronization patterns depending on the adjustment between the fast and slow...

Abstract Dual recycling, the combination of the interferometric techniques of power and signal recycling, allows the improvement of the shot noise limited sensitivity of interferometric gravitational wave detectors. GEO 600 is the first km-scale gravitational wave detector using dual recycling. The hardware installation is completed and dual recycling has become a great challenge in terms of co...

We report on the experimental observation of coherence enhancement of noise-induced intermittency in a semiconductor laser subject to optical injection from another laser at the boundary of the frequency-locking regime. The intermittent switches between locked and unlocked states occur more regularly at a certain value of the injecting laser pump current. A shape of probability distribution of ...

Identifying dual role electrode materials capable of storing both lithium and sodium are thought to be highly relevant, as these materials could find potential applications simultaneously in lithium and sodium ion batteries. In this regard, the concept of dual alkali storage is demonstrated in Fe(3)O(4) anode material undergoing conversion reaction. To enable improved storage, a rational active...

The title compound, C(16)H(19)N(3)O(2), exhibits a trans geometry about the N=N double bond in the triazene unit in the solid state, and individual mol-ecules are close to planar with r.m.s. deviations from planarity of 0.065 Å and 0.242 Å for the two independent molecules in the asymmetric unit. Distinct inter-molecular N-H⋯N hydrogen bonds lead to the formation of dimers with an R(2) (2)(8) g...

We have implemented the hardware of a prototype Phase-Locked Loop (PLL) system in Instrumentaion and Informatics Research Laboratory, Department of Electronics Science, Gauhati University, Assam, India for communication systems. The system is tested using Digital Storage Oscilloscope (DSO) (Model: Tektronix TDS 1012B; 1GS/Sec). We also simulate the system using Circuit Maker’s Berkeley SPICE3f5...

We propose Lavinia, a censorship resistant publishing system that incentivizes document storage through the use of an anonymous, distributed, time-locked payment system. This has the advantage of allowing the publisher to decide whether a document is worth storing, and for how long, instead of relying on public interest or an appointed editorial board. We give a description of related work in c...

A method used to obtain frequencies in precise ratios of 2/3 and 1/3 of the pump is described as a possible way to extend the usable range of octave-spanning optical frequency combs for frequency metrology applications. The divider is based on a selfphase locked optical parametric oscillation in a doubly resonant semi-monolithic optical cavity containing a dual-grating periodically poled lithiu...
