The aim of the paper is to apply the software tool Perseus to modelling of epistemic interactions. We focus on the issue of agents’ knowledge acquisition, using a logical puzzle in which agents increase their knowledge about hats they wear. In the paper, first we present a model of epistemic interactions, which allows to resolve the hats puzzle. Then, the model is used to build the problem’s sp...

This paper is focused on the incorporation of recent techniques for multi-layer perceptron (MLP) based feature extraction in Temporal Pattern (TRAP) and Hidden Activation TRAP (HATS) feature extraction scheme. The TRAP scheme has been origin of various MLP-based features some of which are now indivisible part of state-of-the-art LVCSR systems. The modifications which brought most improvement – ...

We investigate derandomizations of digital good randomized auctions. We propose a general derandomization method which can be used to show that for every random auction there exists a deterministic auction having asymptotically the same revenue. In addition, we construct an explicit optimal deterministic auction for bi-valued auctions.

Histone acetylation is one of the vital reversible modifications of chromatin structure that regulates gene expression in eukaryotes. Histone acetyltransferases (HATs) and histone deacetylases (HDACs) maintain the homeostasis of histone acetylation. Studies in Arabidopsis have revealed that HATs are involved in plant responses to various stresses including light, temperature, salt and ABA. Drou...

Network security deals with two types of communities black hats and white hats. The era of security has come when the white hats are not only interested in defending the networks but are keen to make fool of the black hats. Looking at the other side of the mirror, the black hats have also evolved new methods of breaching the security. The work in this paper is based on implementation of low-int...

In this study, we have investigated genome-wide occurrence of Histone Acetyltransferases (HATs) in genomes of Mus musculus and Danio rerio on the basis of presence of HAT domain. Our study identified a group of proteins that lacks characteristic features of known HAT families, relatively smaller in size and has no other associated domains. Most of the proteins in this unclassified group are Cam...
