BACKGROUND Publication and selective outcome reporting bias are a threat to the validity of systematic reviews. Extensive searching for additional trials in prospective trial registers could reduce this problem. We have evaluated how authors of Cochrane systematic reviews currently make use of trial registers as an additional source for the identification of potentially eligible trials. METHO...

Sequential networks contain combinational logic blocks separated by registers. Application of combinational logic minimization techniques to the separate logic blocks results in improvement that is restricted by the placement of the registers; information about logical dependencies between blocks separated by registers is not utilized. Temporarily moving all the registers to the periphery of a ...

The snapshot object is an important tool for constructing wait-free asynchronous algorithms. We relate the snapshot object to the lattice agreement decision problem. It is shown that any algorithm for solving lattice agreement can be transformed into an implementation of a snapshot object. The overhead cost of this transformation is only a linear number of operations on atomic single-writer mul...

D rummond (2011) eloquently illustrates the Janus-head of MIS using a vivisection of risk registers, noting how, although risk registers are commonly used, they often fail. Drummond finds two root causes for their failure (1) the fog of risk and (2) the surplus reality of risk registers. Drummond first notes that risk registers compile information about the future of the world and the possible ...

The innovative Intel® HyperFlexTM FPGA Architecture features a “registers everywhere” design that includes ubiquitous retiming and pipelining registers, called Hyper-Registers. These Hyper-Registers are available in every routing wire on the device. Combined with the new Intel Quartus® Prime Hyper-Aware design flow, these Hyper-Registers allow designers to break the performance barrier, achievi...

Feedback with Carry Shift Registers (FCSRs) are a promising alternative to LFSRs for the design of stream ciphers. Most of the FCSR-based stream ciphers use a Galois representation. In this case, the control of a single bit leads to the control of the feedback values. This particular property was exploited to break most of the existing proposals. Recently, a new representation for FCSR automata...

In [3], we have introduced vectorial conception of FCSR’s in Fibonacci mode. This conception allows us to easily analyze FCSR’s over binary finite fields F2n for n ≥ 2. In [4], we describe and study the corresponding Galois mode and use it to design a new stream cipher. In this paper, we introduce the Ring mode for vectorial FCSR, explain the analysis of such Feedback registers and illustrate w...

This article presents some new results concerning two algebraic attacks against the F-FCSR constructions proposed in [2]. We focus on the parameters of the stream ciphers proposed that permit to mount algebraic attacks when using the IV mode. The complexity obtained for the first attack described here is 2 binary instructions using 2 known IV values for the construction F-FCSR-SF1. All the prop...

Lexical bundles are frequent word combinations that commonly appear in different registers. They have been the subject of much research in the area of corpus linguistics during the last decade. While most previous studies of bundles have mainly focused on variations in the use of these word combinations across different registers and a number of disciplines, not much research has been done to e...
