The cerebral aneurysm 'clip scissoring' phenomenon resulting from clip blade twisting is an unpredictable surgical complication. Additionally, incomplete clipping resulting from the presence of an atherosclerotic wall in the neck of the aneurysm can also cause unforeseen problems. Here, the authors present an unusual case of incomplete clipping of a large, atheromatous aneurysm resulting from c...

Scissoring of the cerebral aneurysm clip blades is a rare but potentially devastating complication of clipping surgery and results in aneurysm neck injury inducing rupture and/or cerebral infarction. Scissoring has been reported using titanium straight clips. Here we present two unusual cases of crossing of the blades of titanium bayonet clips by a scissors-like mechanism during surgery. The pr...

Scissoring in thick bars suppresses buckling behavior in serpentine traces that have thicknesses greater than their widths, as detailed in a systematic set of analytical and experimental studies. Scissoring in thick copper traces enables elastic stretchability as large as ≈350%, corresponding to a sixfold improvement over previously reported values for thin geometries (≈60%).

Many algorithms and tools exist for the segmentation of 3D meshes. However, they are labor intensive and lack the simplicity of 2D image segmentation systems, limiting them to a small set of expert users. This paper introduces a new segmentation tool which aims for accurate and flexible interactive mesh segmentation, yet maintains an easy-to-use interface suitable for novices and experienced us...

This paper presents an intelligent scissoring operator for meshes. Unlike common approaches that segment a mesh using clustering schemes, we introduce a method that concentrates on the contours for cutting. Our approach is based on the minima rule and part salience theory from cognitive theory. The minima rule states that human perception usually divides a surface into parts along the concave d...

A Vaska-type complex carrying a ferrocene-appended diphosphine ligand was developed as a prototype of autonomous molecular machines that is able to undergo continuous scissoring motion in the presence of diphenylphosphoryl azide and aldehyde.

Automatic license plate recognition (ALPR) system for vehicles is a challenging area of research due to its importance to a wide range of commercial applications. The first and the most important stage for any ALPR system is the localization of the license plate within the image captured by a camera. In this paper proposed approach is present. It has considered the Indian number plates, where r...

Long titanium aneurysm clips have recently been released. In the present study, comparative study of long titanium and cobalt alloy clips was performed. Two kinds of Sugita long clips (straight clips of 25- and 35-mm blade length) made of titanium and cobalt alloys were tested by measuring the closing force, the anti-scissoring torque, and the maximum opening width. There were some differences ...

Binary and tertiary mixture of o~-tocophenol, cholesterol and dimyristoylphosphatidylcholine in the form of multilamellar liposomes were investigated by Fourier Transform Infrared and visible spectroscopy. Results of the FTIR and turbidity experiments indicate that aT decreases or diminishes the effect of cholesterol on the frequency and the bandwidth of the C-H stretching, CH 2 scissoring and ...
