Japanese beetle (Popillia japonica Newman) is an emerging silk-feeding insect found in fields in the lower Corn Belt and Midsouthern United States. Studies were conducted in 2010 and 2011 to evaluate how silk clipping in corn affects pollination and yield parameters. Manually clipping silks once daily had modest effects on yield parameters. Sustained clipping by either manually clipping silks t...

In adaptive dynamic programming, neurocontrol and reinforcement learning, the objective is for an agent to learn to choose actions so as to minimise a total cost function. In this paper we show that when discretized time is used to model the motion of the agent, it can be very important to do “clipping” on the motion of the agent in the final time step of the trajectory. By clipping we mean tha...

OBJECTIVE The presence of a cerebral aneurysm remnant after surgical clipping is associated with a risk of regrowth or rupture. For these recurred aneurysms, coil embolization can be considered as a treatment option. We retrospectively reviewed cases of ruptured or regrown aneurysms after clipping treated by endovascular coil embolization. MATERIALS AND METHODS We conducted a retrospective re...

OBJECTIVE Although surgical techniques for clipping paraclinoid aneurysms have evolved significantly in recent times, direct microsurgical clipping of large and giant paraclinoid aneurysms remains a formidable surgical challenge. We review here our surgical experiences in direct surgical clipping of large and giant paraclinoid aneurysms, especially in dealing with anterior clinoidectomy, distal...

Development of communication systems allows people to easily record and distribute their speech. The clipping-noise, however, degrades the sound quality in the speech recording when gain level of input signals is excessive in the maximum range of an amplitude. In this case, it is necessary to suppress the clippingnoise in the observed speech for improving its sound quality. Although a linear pr...

AIM Surgical outcome for giant intracranial aneurysms (GIA) is suboptimal. Reasons for higher complication rates in large and GIA surgery are the occlusion of perforators or parent arteries during aneurysm clipping, or prolonged temporary occlusion of main arteries. In this article, results of clipping of large and GIAs of anterior circulation are presented. MATERIAL AND METHODS Ten patients ...

Polygon clipping is an important operation that computers execute all the time. An algorithm that clips a polygon is rather complex. Each edge of the polygon must be tested against each edge of the clipping window, usually a rectangle. As a result, new edges may be added, and existing edges may be discarded, retained, or divided. Multiple polygons may result from clipping a single polygon. Afte...

High peak-to-average power ratio is a major problem that is inherent in all multicarrier communication systems. Clipping the high-peak power samples introduces (extra) clipping noise, which degrades the system performance in terms of bit-error rate (BER). Measuring BER usually requires a very long simulation time, as clipping occurs very rarely. In this letter, we propose a method called clippi...

This paper describes an algorithm for clipping of m-dimensional objects that intersect a compact n-dimensional rectangular area. The new algorithm is an extension of a method for line clipping in three dimensions. Motivated by the need for efficient algorithms for example when comparing three-dimensional (3-D) images to each other, our method allows for the incremental computation of the subset...

BACKGROUND AND PURPOSE We have previously reported the difference in length of stay and hospital charges for patients with cerebral aneurysms treated with either clipping or coiling at our institution. We now report an analysis of the same comparison at a national level conducted using the Nationwide Inpatient Sample database. METHODS We obtained the Nationwide Inpatient Sample from the Healt...
