An ordered structure is called o-minimalistic if it has all the first-order features of an o-minimal structure. In this paper, we concentrate on a well-known fragment DCTC (Definable Completeness/Type Completeness) and generalize o-minimal properties to this more general situation (dimension theory, monotonicity, Hardy structures, quasi-cell decomposition) upon replacing finiteness by discreten...

the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...

UNLABELLED The purpose of this study was to determine whether tumor necrosis factor (TNF) contributes to airway hyperresponsiveness (AHR) and migration of polymorphonuclear leukocytes (PMN) into the airways following exposure to ozone (O(3)). Wild-type mice, TNF p55 or p75 receptor knockout mice (p55 TNFR -/- and p75 TNFR -/-), as well as double receptor knockout mice (p55/p75 TNFR -/-), were e...

In this paper we provide algorithms faster thanO(2) for several NP-complete dominationtype problems. More precisely, we provide: • an algorithm for CAPACITATED DOMINATING SET that solves it in O(1.89), • a branch-and-reducealgorithm solving LARGEST IRREDUNDANT SET inO(1.9657) time, • and a simple iterative-DFS algorithm for SMALLEST INCLUSION-MAXIMAL IRREDUNDANT SET that solves it in O(1.999956...

The chemical synthesis of a series of mucin-type oligosaccharide fragments 1-7 containing an α-linked aminopropyl spacer ready for glycoarray attachment is reported. A highly convergent and stereoselective strategy that employs two different orthogonal protected galactosamine building blocks was used to access all of the targets. A tandem deprotection sequence, that did not require chromatograp...

Mucins and mucin-type glycoproteins, collectively referred to as mucin-type O-glycans, are implicated in many important biological functions and pathological conditions, including malignancy. Presently, there is no reliable method to measure the total mucin-type O-glycans of a sample, which may contain one or more of these macromolecules of unknown structures. We report the development of an im...

We present a new optical spectroscopic study of the O-type binary HD 165052 based on highand intermediate-resolution CCD observations. We re-investigated the spectral classification of the binary components, obtaining spectral types of O6.5V and O7.5V for the primary and secondary, respectively, finding that both stars display weak C iii λ5696 emission in their spectra. We also determined a rad...

Recent studies of massive O-type stars present clear evidences of inhomogeneous and clumped winds. O-type (H-rich) central stars of planetary nebulae (CSPNs) are in some ways the low mass–low luminosity analogous of those massive stars. In this contribution, we present preliminary results of our on-going multi-wavelength (FUV, UV and optical) study of the winds of Galactic CSPNs. Particular emp...

We present an analysis of two recently discovered, very hot hydrogen-deficient post-AGB stars of spectral type O(He), namely HS 1522+6615 and HS 2209+8229, by means of state-of-the-art NLTE model atmospheres based on new optical, UV, and X-ray observations. In the spectra of HS 1522+6615 we discovered a variability of the O VI λ 5290Å line complex on a time scale of few days. We also report on ...
