We construct an effective Lagrangian for new strong interactions at the LHC, including as a first step the two lightest triplets of spin-1 resonances. Our parametrization is general enough to allow for previously unstudied spectrum and couplings. Among available frameworks to describe the spin-1 sector, we rely on an extra-dimensional description. Our approach limits the number of parameters ye...

The extent to which plant populations are seed vs. establishment limited can be understood by quantifying the recruitment function, describing the number of seedlings that establish as a function of the number of seeds added. Here, we derive a general equation for the recruitment function based on a mechanistic model describing how the availability of safe sites (sites suitable for germination ...

  Objective: For the assessment of primary arch form, different methods have been used including qualitative classifications, inter-canine and inter-molar widths and quantitative and numerical methods using mathematical models. The purpose of this study was to compare the validity and reliability of Cast Analyzer X Iranian software with those of Curve Expert Professional version 1.1 for arch fo...

We describe parameterized complexity classes by means of classical complexity theory and descriptive complexity theory. For every classical complexity class we introduce a parameterized analogue in a natural way. In particular, the analogue of polynomial time is the class of all fixed-parameter tractable problems. We develop a basic complexity theory for the parameterized analogues of classical...

The architecture of cloud applications differs from traditional software architectures mainly regarding their basic architectural elements, the services, the metadata about the services for expressing information related to quality parameters and pricing models, and the constraints over the applications and the used services. This paper presents Cloud-ADL, a seamless extension of the ACME ADL t...

Automatically generating textual descriptions of numerical data is a particularly useful task with the explosion of accessible online information. A textual description allows people to absorb key features more easily, especially when there are large amounts of data involved. Some work has been done in automatically generating text from data; e.g. Mittal et al. [1995] and Robin and McKeown [199...

• Let L be a set of locations. • Let F ⊂ L be a set of potential facility locations. • Let C ⊂ L be a set of clients (cities). • Let c : L × L → R ∀i, j ∈ L be a distance function. Alternatively think of the function as describing the cost of assigning city j to facility i. • Let f : F → R ∀i ∈ F be a cost function describing the cost of opening a facility at i. • Let φ : C → F ∀j ∈ C be an ass...

This study makes use of the Tsallis entropy to predict the shear stress distribution. Given a definition of the Tsallis entropy, it is maximized by using the probability density function, which then is used to attain a novel shear stress equation. This is then employed for calculating the shear stress distribution in rectangular channels in different aspect ratios and finally, for viability, th...

Thermal quenching is a known and important effect which should be taken into account in studying thermoluminescence (TL) phenomenon. This effect causes the probability of non-radiative recombinations to be increased with raising temperature in TL process. This article deals with changes of the TL glow curve of LiF:Mg, Ti (TLD-100) with heating rate. It was observed that the main dosimetry peak ...

The twisting function describing nonstandard (super-Jordanian) quantum deformation of osp(1|2) is given in explicite closed form. The quantum coproducts and universal R-matrix are presented. The non-uniqueness of twisting function as well as two real forms of deformed osp(1|2) superalgebras are considered. One real quantum osp(1|2) superalgebra is interpreted as describing the κ-deformation of ...
