In this paper, the notion of βS∗−compactness is introduced in L−fuzzy topological spaces based on S∗−compactness. A βS∗−compactness L-fuzzy set is S∗−compactness and also β−compactness. Some of its properties are discussed. We give some characterizations of βS∗−compactness in terms of pre-open, regular open and semi-open L−fuzzy set. It is proved that βS∗−compactness is a good extension of β−co...

Suppose that λ − T is left-invertible in L(H) for all λ ∈ Ω, where Ω is an open subset of the complex plane. Then an operator-valued function L(λ) is a left resolvent of T in Ω if and only if T has an extension T̃ , the resolvent of which is a dilation of L(λ) of a particular form. Generalized resolvents exist on every open set U , with U included in the regular domain of T . This implies a form...

It is known by A. Loi and R. Piergallini that a closed, oriented, smooth 3manifold is Stein fillable if and only if it has a positive open book decomposition. In the present paper we will show that for every link L in a Stein fillable 3-manifold there exists an additional knot L to L such that the link L ∪ L is the binding of a positive open book decomposition of the Stein fillable 3-manifold. ...

BACKGROUND Although clinical studies of the high-flow nasal cannula (HFNC) and its effect on positive end-expiratory pressure (PEEP) have been done, the washout effect has not been well evaluated. Therefore, we made an experimental respiratory model to evaluate the respiratory physiological effect of HFNC. METHODS An airway model was made by a 3D printer using the craniocervical 3D-CT data of...

tio2 nanoparticles were synthesized by modified sol—gel method using pure room temperature ionic liquid(rtil) 2-hydroxyethylammonium formate as a reaction medium. the structure and morphology of tio2nanoparticles were characterized with x-ray powder diffraction (xrd), bet surface analysis and scanningelectron microscopy (sem). tio2 nanoparticles were synthesized in open and closed vessels. the ...

Raspberries composed of various varieties, are popular ingredients of daily diet with highly distinguished biological activities. In this study, a comparative investigation was conducted on various chemical potential of methanol extracts from Rubus loganobaccus L. leaf parts cultured in greenhouse and open-field. Biochemical activity of the extracts obtained from the field cul...

the goal of this study was to determine the effects of the l-type calcium channel blockers verapamil and diltiazem on the currents of voltage-gated potassium channel (fkv1.4δn), an n-terminal-deleted mutant of the ferret kv1.4 potassium channel. measurements were made using a two electrode voltage clamp technique with channels expressed stably in xenopus oocytes. the fkv1.4δn currents displayed...

BACKGROUND In patients with open neural tube defects, the incidence of scoliosis and requirement for spinal fusions are increased. Historically, there has been no standardized measurement of vertebral morphometry in these patients. However, anecdotally, patients with open neural tube defects have a more medially oriented lumbar pedicle trajectory than the average population. METHODS A single-...
