We discuss joint work with B. Hughes, S. Weinberger and B. Williams [7] on some examples of stratified spaces with two strata. We will describe the structure of neighborhoods of the lower stratum in the whole space in general and give some specific calculations when the lower stratum is a circle. Using some known K-theory calculations we produce examples where the neighborhood “improves” under ...

We construct some non-essential H-closed epireflections of W, the category of archimedean l-groups with weak order unit, that are not comparable with any known H-closed epireflections of W other than the divisible hull and the epicompletion. In preparation, we show that the free objects in any Hclosed epireflective subcategory of W must be closed under composition (see section 2 for a precise d...

An experimental investigation was carried out to study mixed convection heat transfer from Al2O3-water nanofluid inside a vertical, W-shaped, copper-tube with uniform wall temperature. The tests covered different ranges of some involved parameters including Reynolds number, temperature and particles volume fraction. The results showed that the rate of heat transfer coefficient improved with Rey...

Mathematical models of complex objects in the form interval difference equations are built on basis obtained experimental data within limits inductive approach. At same time, interpretation physical properties object base such model is enough. A method transformation a mathematical differential was proposed article. The based formulas for representing values function at node grid Taylor series ...

Marginal Fisher Analysis (MFA) is a novel dimensionality reduction algorithm. However, the two nearest neighborhood parameters are difficult to select when constructing graphs. In this paper, we propose a nonparametric method called Marginal Discriminant Projection (MDP) which can solves the problem of parameters selection in MFA. Experiment on several benchmark datasets demonstrated the effect...

New DNA sequencing technology implemented in the GS 20 sequencer reduces cost and time in exchange for lower accuracy. DNA sequencing errors negatively impact downstream applications and therefore accurate base calls and error probabilities are invaluable to researchers. This paper applies a graphical model to the base calling problem in context of the GS 20 sequencer. This model integrates sig...

In Rough Set Theory, dependency in the knowledge base is an important aspect when drawing inferences about the world. Rough set (inexact set) is defined by using a fixed binary relation (equivalence relation, tolerance relation, similarity relation, etc) to analyze vague, imprecise, inexact problems, which satisfy many interesting properties. The neighborhood based rough set theory is an extens...

For a compact monotonically normal space X we prove: (1) X has a dense set of points with a well-ordered neighborhood base (and so X is co-absolute with a compact orderable space); (2) each point of X has a well-ordered neighborhood πbase (answering a question of Arhangel’skii); (3) X is hereditarily paracompact iff X has countable tightness. In the process we introduce weak-tightness, a notion...

a suitable emulgel formulation of piroxicam was prepared and its percutaneous permeation was investigated using wistar rat skin and diffusion cell technique. the concentrations of the drug in receptor phase of diffusion cells were measured using hplc method. the effect of three types of penetration enhancers (myrj 52, cineol and transcutol p) with different concentrations on transdermal permeat...

We report here nearly complete genome sequence of Inhangapi virus (INHV) strain BEAR177325, which was isolated from a pool of sandflies (Lutzomyia flaviscutellata) in the Utinga neighborhood, Belém (01º28´S 48°27'W), State of Pará, Brazil, in 1969. The genome of this virus showed similarity with members belonging to the family Rhabdoviridae.
