One-Block CYRCA is an automated procedure for identifying multiple-block alignments from single block queries (http://bioinfo.weizmann.ac.il/blocks/OneCYRCA). It is based on the LAMA and CYRCA block-to-block alignment methods. The procedure identifies whether the query blocks can form new multiple-block alignments (block sets) with blocks from a database or join pre-existing database block sets...

Despite the fact that we evidently have very good block ciphers at hand today, some fundamental questions on their security are still unsolved. One such fundamental problem is to precisely assess the security of a given block cipher with respect to linear cryptanalysis. In by far most of the cases we have to make (clearly wrong) assumptions, e.g., assume independent round-keys. Besides being un...

Security mechanisms to protect our systems and data from malicious adversaries have become essential. Strong encryption algorithms are an important building block of these solutions. However, each application has its own requirements and it is not always possible to find a cipher that meets them all. This work compares unrolled combinatorial hardware implementations of six lightweight block cip...

We address the problem of finding the minimal number of block interchanges required to transform a duplicated unilinear genome into a single tandem duplicated unilinear genome. We provide a formula for the distance as well as a polynomial time algorithm for the sorting problem. This is the revised and extended version of [8].

An iterative block decision feedback equalizer (IB-DFE) for single carrier modulation is proposed. Filtering operations are implemented by discrete Fourier transforms (DFTs) which yield a reduced computationals complexity, for both filter design and signal processing, when compared to existing DFEs. Moreover, the new IB-DFE allows to cancel, besides postcursors, also the precursors of the iters...

The aim of this study was to investigate the anesthetic effect and risk of epinephrine for subcutaneous single injection digital block. Either 3.0 mL 1.0% Lidocaine or a 3.0 mL 1.0% Lidocaine with (1 : 100,000) epinephrine was injected into the subcutaneous space at the middle point of the palmar digital crease of the 18 middle fingers of 9 healthy volunteers. The SpO(2) of the fingers decrease...
