Coding for Cryptographic Security Enhancement Using Stopping Sets [PDF]

IEEE Transactions on Information Forensics and Security, 2011
In this paper we discuss the ability of channel codes to enhance cryptographic secrecy. Toward that end, we present the secrecy metric of degrees of freedom in an attacker's knowledge of the cryptogram, which is similar to equivocation. Using this notion of secrecy, we show how a specific practical channel coding system can be used to hide information ...

Genetic algorithm efficiency improvement in the course of set cover problem solution

Advanced Engineering Research, 2019
Introduction. Practical tasks (location of service points, creation of microcircuits, scheduling, etc.) often require an exact or approximate to exact solution at a large dimension.

Pathwise inequalities for local time : applications to skorokhod embeddings and optimal stopping [PDF]

, 2007
We develop a class of pathwise inequalities of the form H(B-t) >= M-t + F(L-t), where B-t is Brownian motion, L-t its local time at zero and M-t a local martingale.

Limited Gradient Descent: Learning With Noisy Labels

IEEE Access, 2019
Label noise may affect the generalization of classifiers, and the effective learning of main patterns from samples with noisy labels is an important challenge.

Improved Sequential Stopping Rule for Monte Carlo Simulation [PDF]

, 2008
This letter presents an improved result on the negative-binomial Monte Carlo technique analyzed in a previous paper (L. Mendo and J. M. Hernando, ``A simple sequential stopping rule for Monte Carlo simulation,'' IEEE Trans. Commun., vol. 54, no.

An efficient, scalable, and adaptable framework for solving generic systems of level-set PDEs

Frontiers in Neuroinformatics, 2013
In the last decade, level-set methods have been actively developed for applications in image registration, segmentation, tracking, and reconstruction. However, the development of a wide variety of level-set PDEs and their numerical discretization schemes,

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Robust Invariant Set Design for Reliable Stopping in Adaptive Cruise Control via Model Predictive Control

IEEE Access
Adaptive cruise control (ACC) systems are critical for ensuring safe and efficient operation in autonomous vehicles, especially in scenarios requiring precise stopping, such as approaching traffic lights or handling emergency braking.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
