Periodontitis is a systemic and chronic inflammatory disease associated with multiple physical conditions. Distress and depression are other problems affecting the progression of periodontitis. However, the causal relationship between depression and periodontitis has not been adequately investigated. This aim of this study was to determine the association between periodontitis and the subsequen...

The classical Eulerian polynomials are defined by setting An(t) = ∑ σ∈Sn t = n ∑ k=1 An,kt k where An,k is the number of permutations of length n with k − 1 descents. Let An(t, q) = ∑ π∈Sn t 1+des(π)qinv(π) be the inv q-analogue of the classical Eulerian polynomials whose generating function is well known: ∑ n>0 uAn(t, q) [n]q! = 1 1− t ∑ k>1 (1− t)kuk [k]q! . (0.1) In this paper we consider pe...

For the first time, crystal structures of new quaternary compounds were studied by powder method. They crystallize in tetragonal system, Sp.Gr. I-4, structural type CuIn2Te3Cl, with cell parameters: AgGa2Se3Cl (a = 5.9789(3) Å, c 10.8592(7) Å), AgGa2Se3Br 5.9767(3) 10.8558(7) Å). From analysis structure it was found that researched belong to semiconductors general formula AІВІІІ2XVI3YVII (AІ – ...

We give an anecdotal discussion of the problem of searching for polynomials with all roots on the unit circle, whose coefficients are rational numbers subject to certain congruence conditions. We illustrate with an example from a calculation in p-adic cohomology made by Abbott, Kedlaya, and Roe, in which (using an implementation developed with Andre Wibisono) we recover the zeta function of a s...

gnasi Rius uan José Villanueva omputer Vision Center and niversidad Autònoma de Barcelona ellaterra, Barcelona, Spain Abstract. Though it is the first step of a real video surveillance application, detection has received less attention than tracking in research on video surveillance. We show, however, that the majority of errors in the tracking task are due to wrong detection. We show this by e...

Methodologies and algorithms are presented for the secure cooperation of a team of autonomous mobile underwater sensors, connected through an acoustic communication network, within surveillance and patrolling applications. In particular, the work proposes a cooperative algorithm in which the mobile underwater sensors (installed on Autonomous Underwater Vehicles-AUVs) respond to simple local rul...

Cultivation of perennials such as Miscanthus x giganteus Greef et Deuter (Mis) combines the provision ecosystem services and generation additional carbon sources for farming. The potential Mis based fertilisers, regarding immobilisation inorganic nitrogen (N) build-up soil organic matter (SOM), was tested in a field trial. Therefore, crop rotation winter barley (Hordeum vulgare L.), mustard (Si...

Adequate fertility combined with effective weed management is important in maximizing corn (Zea mays L.) grain yield. Corn uptake of nitrogen (N) is dependent upon many factors including weed species and density and the rate and formulation of applied N fertilizer. Understanding interactions among corn, applied N, and weeds is important in developing management strategies. Field studies were co...
