BACKGROUND AND PURPOSE Patients with carotid-cavernous fistula (CCF) may undergo direct or indirect shunting. Ultrasonography has value that is complementary to angiography in the assessment and follow-up of these patients. The aim of this study was to characterize findings provided by carotid duplex sonography (CDS) and transcranial color-coded duplex sonography (TCCD) in patients with differe...

The Bloom filter—or, more generally, an approximate membership query data structure (AMQ)— maintains a compact, probabilistic representation of a set S of keys from a universeU . An AMQ supports lookup, and possibly insert and delete operations. If x ∈ S, then lookup(x) returns “present.” If x 6∈ S, then, lookup(x) may return “present” with probability at most ε, where ε is a tunable false-posi...

Abstract To estimate the phase velocity using array observations of microtremors, some algorithms for estimation include constraints on shape, such as equilateral triangles or placement receivers a circle, in order to reduce error velocity. In present study, direct technique is introduced records obtained through an with arbitrary shape based complex coherency function (CCF), where CCF defined ...

BACKGROUND While there is much data on cardiac problems of adults, there is a limited statistical data available to evaluate the magnitude of the cardiac problems in children in Pakistan. Many of these children present with recurrent chest infections and congestive cardiac failure (CCF), and are managed by general practitioners. A careful search for underlying cardiac problems and awareness abo...

Continuous-cover forestry (CCF) has been recognized for the production of multiple ecosystem services, and is seen as an alternative to clear-cut forestry (CF). Despite the increasing interest, it is still not well described how CCF would affect the carbon balance and the resulting climate benefit from the forest in relation to CF. This study compares carbon balances of CF and CCF, applied as t...

Embolization of a carotid cavernous fistula (CCF) by means of a detachable balloon is an established method for treating CCFs while preserving a patent parent internal carotid artery (ICA). However, failure to embolize the CCF may occur on a few occasions, such as when the balloon cannot pass through the fistula into the cavernous sinus by blood flow, or when the inflated balloon in the caverno...

OBJECTIVE To evaluate heart failure in patients with pneumonia. SETTING The paediatric wards of a tertiary hospital in Nigeria. SUBJECTS One hundred and four patients were studied. RESULTS The mean age was 10.3 ± 11.0 months and 53(51.0%) were males. Of the 104, 41(39.4%) also had Congestive Cardiac Failure (CCF). All 41(100%) patients with CCF compared to 38 of 63 (60.3%) with pneumonia ...

The investigation of the static and dynamic structural properties of colloidal systems relies on techniques capable of atomic resolution in real space and femtosecond resolution in time. Recently, the cross-correlation function (CCF) analysis of both X-rays and electron diffraction patterns from dilute and dense aggregates has demonstrated the ability to retrieve information on the sample's loc...

The effects of widespread conifer afforestation on the acidity of lakes and streams in the acid sensitive uplands of the UK has been researched extensively and has contributed to the development and implementation of national forest management guidelines (e.g. Forest and Water Guidelines; Forestry Commission, 1993). However, a recent policy document (Woodlands for Wales; National Assembly for W...
