In the nucleolus the U3 snoRNA is recruited to the 80S pre-rRNA processing complex in the dense fibrillar component (DFC). The U3 snoRNA is found throughout the nucleolus and has been proposed to move with the preribosomes to the granular component (GC). In contrast, the localization of other RNAs, such as the U8 snoRNA, is restricted to the DFC. Here we show that the incorporation of the U3 sn...

In this paper, we develop a scalable VLSI architecture employing a two-channel quadrature mirror filter (QMF) lattice for the one-dimensional (1-D) discrete wavelet transform (DWT). We begin with the development of systematic scheduling, which determines the filtering instants of each resolution level, on the basis of a binary tree. Then input–output relation between lattices of the QMF bank is...

We investigate the performance of First-In, FirstOut (FIFO) queues over wireless networks. We characterize the stability region of a general scenario where an arbitrary number of FIFO queues, which are served by a wireless medium, are shared by an arbitrary number of flows. In general, the stability region of this system is non-convex. Thus, we develop a convex inner-bound on the stability regi...

In response to the call for candidates issued by the National Institute for Standards and Technologies (the Advanced Encryption Standard project) the Ecole Normale Sup erieure proposed a candidate called DFC as for \Decorrelated Fast Cipher", based on the decorrelation technique that provides provable security against several classes of attacks (in particular the basic version of Biham and Sham...

In this paper, we consider feedback control that stabilizes unstable periodic orbits (UPOs) of chaotic discrete-time systems. First, we show that there exists a strong necessary condition for stabilization of the UPOs when we use delayed feedback control (DFC) that is known as one of useful methods for controlling chaotic systems. The condition is similar to that in the xed point stabilization ...

Engagement of persons living with dementia in public consultations is central to the development dementia-friendly communities (DFC). However, due a lack resources and expertise how support their involvement, are not always involved processes for planning implementation DFC initiatives. To better understand methods that facilitate engagement consultations, we evaluated consultation Canadian ini...
