The article attempts to systematize the key factors of development domestic tourism industry. influence external and internal on growth or, conversely, shrinking tourist market is determined. that have greatest impact current state international national are considered. And also contributing overcoming crisis in industry identified.

Two polymorphic types and are said to be bicoercible if there is a coercion from to and conversely. We give a complete equational axiomatization of bicoercible types and prove that the relation of bicoercibility is decidable.

To evaluate the utility of the CT bronchus sign in making a choice between transbronchial biopsy (TBB) and transthoracic needle aspiration (TTNA) as the first diagnostic procedure in a patient with a solitary pulmonary nodule (SPN), we reviewed the results of TBB and TTNA in 26 patients who had a bronchogenic carcinoma less than 3 cm, studied with thin-section CT. The patients were divided into...

The finite model property of the equational fragment of the theory of Kleene algebras is a consequence of Kozen’s [3] completeness theorem. We show that, conversely, this completeness theorem can be proved assuming the finite model property of this fragment.

Two-step verification does not imply two-factor authentication. Conversely, two-factor authentication may not require two-step verification. With ubiquitous bio-sensors, we can strive for one-step two-factor authentication for wearable computing applications.

Proving the chaoticity of some dynamical systems is equivalent to solving the hardest problems in mathematics. Conversely, classical physical systems may "compute the hard or even the incomputable" by measuring observables which correspond to computationally hard or even incomputable problems.

Optical sensor arrays typically require a large set of chemically responsive colorants to enhance discrimination capability. Conversely, we have proven that by using multiple concentrations of one indicator, the discrimination of various analytes could be realized.

The coordinate projective line over a field is seen as a groupoid with a further ‘projection’ structure. We investigate conversely to what extent such an, abstractly given, groupoid may be coordinatized by a suitable field constructed out of the geometry.

We consider the metric transformation of measure spaces/pyramids. clarify conditions to obtain convergence sequence transformed spaces from that original sequence, and, conversely, respectively. As an application, we prove spheres and projective with standard Riemannian distance converge a Gaussian space Hopf quotient space, respectively, as dimension diverges infinity.
