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 Healthc...

Microsurgical clipping remains a durable treatment for intracranial aneurysms. Despite the low rate of re-treatment, recurrence of subarachnoid hemorrhage is 3% within the first 10 years. This may be caused by rupture of a recurrent or residual aneurysm at the clip site or by rupture of another untreated aneurysm. We investigated the natural history of aneurysms treated with microsurgical clipp...

Abstract Studies investigating the effect of aboveground herbivory on plants often use clipping to simulate effects herbivores, for practical reasons. However, herbivore movements and transfer oral secretions during may cause a different response in plant physiology morphology compared clipping. While studies have real vs. biomass production, physiology, shoot morphology, no study has such root...

BACKGROUND AND PURPOSE Both endovascular and surgical options are available for treatment of unruptured cerebral aneurysms. We conducted a study to determine the costs versus Medicare reimbursement for hospitalization of these patients, which is important information for understanding the economic impact of these patients on hospitals. MATERIALS AND METHODS Using the NIS, we identified hospit...

We investigate iterative receive algorithms for orthogonal frequency division multiplexing (OFDM) transmission affected by clipping at the transmit power amplifier (PA). One algorithm aims at minimizing the Euclidean distance to the received sequence, while the other reconstructs the clipping noise. Both methods significantly reduce the BER compared to simple zero forcing, even for severe clipp...

BACKGROUND Unruptured saccular intracranial aneurysm (SIA) is associated with an increased prevalence of migraine, but it is unclear whether this is altered by clipping of the aneurysm. The aim of our study was to determine whether remission rate of migraine and other recurrent headaches was greater in patients with SIA after clipping than in controls. METHODS We prospectively studied 87 SIA ...

in this experiment 144 hy-line (w36) laying hens, 65 to 77 weeks of age were separated into 4 treatments with 3 replicates (12 birds per replicate) in a completely randomized design experiment. the grass clipping wastes incorporated into a complete formulated layer diet, consisting on a corn and soybean based diet, were 0, 1.5, 3.0 and 4.5% in 1 to 4 experimental groups. the results showed that...

Peak to Average Power Ratio (PAPR) is one of most detrimental aspects in any wireless communication system using multicarrier modulation technique like OFDM, which cause power degradation and spectral spreading. Due to the simplest way for PAPR reduction, clipping technique has been proposed and seems to be promising for use in commercial system. In this paper, we mainly focus on Amplitude clip...

In this issue of JMB, Rajendar and Lucius report a study of themechanism of polypeptide translocation catalyzed by the Escherichia coli ClpA enzyme—the motor component of the ATP-dependent protease, ClpAP. ATP-dependent proteases play important roles in protein turnover and share a common architecture across organisms. ClpAP is composed of the hexameric AAA+ motor protein ClpA and the tetradeca...

A 45-year-old woman presented with kissing aneurysms located at the junctions of the internal carotid artery and the duplicate anterior choroidal arteries manifesting as acute subarachnoid hemorrhage. The aneurysms were clipped during temporary occlusion of the internal carotid artery. Surgery for kissing aneurysms requires special consideration including analysis of the anatomical relationship...
