Abstract We propose a model explaining the origin of transient/episodic jets in black hole X-ray binaries, which they are caused by transitions from collimated, strongly magnetized jet to wide, uncollimated outflow. The change occurs when accretion flow leaves magnetically choked state due an increase rate for weakly varying magnetic flux. formed powerful then detaches its base, and propagates ...

background and objective: different mechanisms may lead to the development of soft tissue tumor-like lesions in the oral cavity. many of these lesions can be identified as specific entities on the basis of their histopathological features and are divided into fibrous, vascular, and giant cell types. the purpose of this study was to establish the relative prevalence of the different histopatholo...

introduction: peripheral reactive lesions of soft tissue are common oral lesions that dentists face during routine examinations. diagnosis and development of a treatment plan is difficult if dentists are not aware of the prevalence and clinical symptoms of these lesions. the frequency of these lesions differs across various populations. the aim of this study was to determine the frequency and d...

in this paper, the concept of {sl local base with  stratifiedstructure} in $i$-topological vector spaces is introduced. weprove that every $i$-topological vector space has a balanced localbase with stratified structure. furthermore, a newcharacterization of $i$-topological vector spaces by means of thelocal base with stratified structure is given.

The anatomical characteristics of the culms and culm bases ssanggol- min-bamboo, which are mutated species Phyllostachys bambusoides, were investigated using optical microscopy to understand material properties. vascular bundles in both type I. There a few abnormal base ssanggol-bamboo, more developed fiber inner part min-bamboo. A wavy surface was observed pith cavity ssanggol-bamboo culms. In...

some of the adamantane properties were calculated in this study. chemical shift, free energy ofsolvation, free energy of cavity formation, henry's law constant, and other properties ofadamantane in dry phase, three solvents and three temperatures have been calculated with abinitio method base on density functional theory (dft) at b3lyp/6-31g, b31yp/6-31g*, b3lyp/6-31+g* and b3lyp/6-31++g** leve...

This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavity injection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage. The complexities and principles of cavity layout design as well as various dependencies in injection mould design are introduced. The knowledge in cavity layout design is ...

BACKGROUND Primary nasal natural killer (NK)/T-cell lymphoma is the most common cellular subtype seen in nasal lymphomas. It is rare in the Western population but occurs more frequently in Asia, South America, and Mexico. The purpose of this study was to describe the computed tomography (CT) and magnetic resonance (MR) imaging findings of primary nasal NK/T-cell lymphoma. METHODS During the p...
