Periodicities of 15 cyclic sections of the Cisco Group are tested through gamma and spectral analyses. The sections are composed of marine and nonmarine carbonate and siliciclastic rocks deposited on the Eastern Shelf, north-central Texas, in Late Pennsylvanian and Early Permian time. Gamma analysis generates facies-dependent thickness–time conversion factors (g’s) to construct g-corrected time...

BACKGROUND Altered septal curvature and left ventricular (LV) geometry secondary to right ventricular (RV) dilation render two-dimensional assessment of LV mechanics difficult in repaired tetralogy of Fallot (TOF) patients. The novel three-dimensional (3D) speckle tracking echocardiography enables comprehensive evaluation of true 3D LV mechanics. METHODS AND RESULTS Seventy-six patients aged ...

Fifty-two B cell non-Hodgkin's lymphomas, in which the diagnosis was based on immunological, cytochemical, and ultrastructural studies, were characterised by morphometry on plastic-embedded tissue sections. Parameters studied were: nuclear size, cytoplasmic area, cytoplasm to nucleus ratio, nuclear contour index, nucleolar size, location of nucleoli within the nucleus, as expressed by relative ...

A recent study showed that posterior circulation plaques have a greater capacity for positive remodeling in a non-Asian population. We aimed to investigate if the features of plaques in the middle cerebral artery (MCA) were different from those in the basilar artery (BA) in a northern Chinese population. We retrospectively analysed the records of 71 consecutive patients with acute ischemic stro...

BACKGROUND Abnormalities in right ventricular function are known to occur in patients with pulmonary arterial hypertension. OBJECTIVE Test the hypothesis that chronic elevation in pulmonary artery systolic pressure delays mechanical activation of the right ventricle, termed dyssynchrony, and is associated with both symptoms and right ventricular dysfunction. METHODS Fifty-two patients (mean...

We measured two- and three-line spatial interval and alignment thresholds for a wide range of separations and eccentricities. In order to avoid confounding the role of separation and eccentricity, the test lines were presented on iso-eccentric arcs, with radii between 0.625 and 10 deg. The iso-eccentric paradigm allows separation to be varied over a large range while holding eccentricity consta...

Topological indices are mathematical descriptors for molecular structures. These used to describe physico-chemical properties such as solubility, shape and weight. In this paper, we present distance-based topological Wiener index hyper-Wiener by using Hosoya polynomial inverse graphs associated with finite cyclic group. Also, have found eccentricity based of

Using the characteristic property of chordal graphs that they are the intersection graphs of subtrees of a tree, Erich Prisner showed that every chordal graph admits an eccentricity 2approximating spanning tree. That is, every chordal graph G has a spanning tree T such that eccT (v) − eccG(v) ≤ 2 for every vertex v, where eccG(v) (eccT (v)) is the eccentricity of a vertex v in G (in T , respect...
