Classification of chromosome segregation errors in cancer.
Abnormal chromosome segregation at mitosis is one way by which neoplastic cells accumulate the many genetic abnormalities required for tumour development. In this paper, a straightforward morphology-based classification of chromosome segregation errors in cancer is suggested. This classification distinguishes between abnormalities in spindle symmetry (spindle multipolarity, size-asymmetry of ana-t

Time delay between symptom and surgery in patients with carotid artery stenosis.
Andgren S, Sjöberg L, Norrving B, Lindgren A. Time delay between symptom and surgery in patients with carotid artery stenosis. Acta Neurol Scand: DOI: 10.1111/j.1600-0404.2010.01478.x. © 2011 John Wiley & Sons A/S. Objectives - Many severe strokes are preceded by warning signs such as a transient ischemic attack or stroke with minor deficits. Carotid endarterectomy (CEA) of a symptomatic carot
Classification of paroxysmal and persistent atrial fibrillation in ambulatory ECG recordings
The problem of classifying short atrial fibrillatory segments in ambulatory ECG recordings as being either paroxysmal or persistent is addressed by investigating a robust approach to signal characterization. The method comprises preprocessing, estimation of the dominant atrial frequency for the purpose of controlling the subbands of a filter bank, and computation of the relative subband (harmonics
Direct and inverse scattering in the time domain for a dissipative wave equation. Part 1: Scattering operators
This is the first part of a series of papers devoted to direct and inverse scattering of transient waves in lossy inhomogeneous media. The medium is assumed to be stratified, i.e., it varies only with depth. The wave propagation is modeled in an electromagnetic case with spatially varying permittivity and conductivity. The objective in this first paper is to analyze properties of the scattering op

Double-edge-triggered D-flip-flop for high speed CMOS circuits
Two circuits are proposed for double edge-triggered D flip-flops (DETDFFs). A DETDFF responds to both edges of the clock pulse. As compared with positive or negative edge-triggered flip-flops, a DETDFF has advantages in terms of power dissipation and speed. Delay figures for these circuits are measured by simulation. It is shown that these circuits are faster and have lower transistor counts than

Words that go together well: developing test formats for measuring learner knowledge of English collocations
This paper describes the development of two test formats, COLLEX and COLLMATCH, measuring receptive recognition knowledge of English verb +NP collocations, and reports findings from pilots and initial test administrations involving Swedish upper-secondaryschool and university level learners. Administrations of the test formats produced highly reliable scores and the performance of native speakers
