Fragmentation of metastable SF(6)(-*) ions formed in low energy electron attachment to SF(6) has been investigated. The dissociation reaction SF(6)(-*)-->SF(5) (-)+F has been observed approximately 1.5-3.4 micros and approximately 17-32 micros after electron attachment in a time-of-flight and a double focusing two sector field mass spectrometer, respectively. Metastable dissociation is observed...

BACKGROUND To identify a correlation between the submandibular fossa (SF) visibility and mandibular canal (MC) cortication on panoramic image and the depth of SF measured on CBCT and also correlation between the depth of SF and vertical and horizontal location of MC on CBCT. MATERIAL AND METHODS 500 CBCT scans and panoramic radiographs were evaluated. SF depth types were classified as type I ...

Trapping of electrons in stacking fault SF interface states may lower the energy of a SF more than it costs to form the SF. This “electronic stress” driving force for SF expansion is evaluated for single and double stacking faults in 4H-SiC in terms of a two-dimensional free-electron density of states model based on first-principles calculations. In contrast with previous work, which claimed th...

BACKGROUND The SF-36 and SF-12 summary scores were derived using an uncorrelated (orthogonal) factor solution. We estimate SF-36 and SF-12 summary scores using a correlated (oblique) physical and mental health factor model. METHODS We administered the SF-36 to 7,093 patients who received medical care from an independent association of 48 physician groups in the western United States. Correlat...

Steroidogenic factor 1 (SF-1 or NR5A1) is a nuclear receptor that controls adrenogenital cell growth and differentiation. Adrenogenital primordial cells from SF-1 knockout mice die of apoptosis, but the mechanism by which SF-1 regulates cell survival is not entirely clear. Besides functioning in the nucleus, SF-1 also resides in the centrosome and controls centrosome homeostasis. Here, we show ...

and Applied Analysis 3 Definition 2.1. Given F,G ∈ Mnm and an indeterminate s ∈ F, the matrix pencil sF−G is called regular when m n and det sF −G / 0 where 0 is the zero element of M 1,F . In any other case, the pencil is called singular. In this paper, as we are going to see in the next paragraph, we consider the case that the pencil is singular. The next definition is very important, since t...

OBJECTIVES We aimed to develop and validate Kinyarwanda versions of Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ) and Short-Form Nepean Dyspepsia Index (SF-NDI) to measure the frequency and severity of dyspepsia and associated quality-of-life impact in Rwanda. SETTING A single, tertiary care centre in Rwanda. PARTICIPANTS 200 consecutive Kinyarwanda-speaking patients referred to endosco...

BACKGROUND Although stent fracture (SF) after sirolimus-eluting stent (SES) implantation has been recognized as one of the predisposing factors of in-stent restenosis, it remains uncertain whether SF can increase the risk of major adverse cardiac events (MACE), especially beyond 1 year after SES implantation. The aim of this study was to assess the impact of SF relative to non-SF on 4-year clin...
