The problem of constructing polynomials with all coefficients 1 or −1 and large merit factor (equivalently with small L norm on the unit circle) arises naturally in complex analysis, condensed matter physics, and digital communications engineering. Most known constructions arise (sometimes in a subtle way) from difference sets, in particular from Paley and Singer difference sets. We consider th...

We consider a class of mean field games in which the agents interact through both their states and controls, we focus on situations generic agent tries to adjust her speed (control) an average (the is made neighborhood state space). In such cases, monotonicity assumptions that are frequently theory do not hold, uniqueness cannot be expected general. Such model lead systems forward-backward nonl...

MOTIVATION Since the protein structure database has been growing very rapidly in recent years, the development of efficient methods for searching for similar structures is very important. RESULTS This paper presents a novel method for searching for similar fragments of proteins. In this method, a hash vector (a vector of real numbers) is associated with each fixed-length fragment of three-dim...

Background. It is well known that overarm throwing is one of the most performed activities in the handball. Shoulder and glenohumeral injuries incidence are high in handball because of both pass, and shooting activity was executed repeatedly in high angular speed. Objectives. This study set out to investigate the usefulness of inexpensive commercial inertial movement sensors for prediction of ...

many graph theoretical parameters have been used to describe the vulnerability of communication networks, including toughness, binding number, rate of disruption, neighbor-connectivity, integrity, mean integrity, edgeconnectivity vector, l-connectivity and tenacity. in this paper we discuss integrity and its properties in vulnerability calculation. the integrity of a graph g, i(g), is defined t...

In this study, we aimed at studying the benefit of Urtica dioica root extract in the management of allergic rhinitis. In a randomized double blind clinical trial, 74 patients with the signs and symptoms of allergic rhinitis and a positive skin prick test were randomly divided into 2 groups. The study group was treated with routine allergic rhinitis treatment and Nettle root extract (Urtidin®, B...
