Post-translational modifications (PTMs) of histone proteins play a fundamental role in regulation of DNA-templated processes. There is also growing evidence that proteolytic cleavage of histone N-terminal tails, known as histone clipping, influences nucleosome dynamics and functional properties. Using top-down and middle-down protein analysis by mass spectrometry, we report histone H2B and H3 N...

Volume clipping is a useful aid for exploring volumetric datasets. To maximize the effectiveness of this technique, the clipping geometry should be flexibly specified and the resulting images should not contain artifacts due to the clipping techniques. We present an improvement to an existing illumination model for volume clipping to allow sharp edges in the data to stay visible. These sharp ed...

OBJECTIVE To evaluate the clinical outcome of coil embolization for unruptured intracranial aneurysm (UIA) with oculomotor nerve palsy (ONP) compared with surgical clipping. METHODS A total of 19 patients presented with ONP caused by UIAs between Jan 2004 and June 2008. Ten patients underwent coil embolization and nine patients surgical clipping. The following parameters were retrospectively ...

OFDM combined with TDM (OFDM/TDM) can be used to reduce a high peak-to-average power ratio (PAPR) of OFDM, but the PAPR reduction is not sufficient. To further reduce the PAPR, an amplitude clipping can be applied. In this letter, we investigate the effect of clipping on OFDM/TDM with and without channel coding. It is shown that amplitude clipped OFDM/TDM has an advantage over clipped OFDM with...

MATERIALS AND METHODS: Hospitalizations for clipping or coiling of unruptured cerebral aneurysms from 2001 to 2008 were identified by cross-matching ICD codes for the diagnosis of unruptured aneurysm (437.3) with procedural codes for clipping (39.51) or coiling (39.52, 39.79, or 39.72) of cerebral aneurysms and excluding all patients with a diagnosis of subarachnoid hemorrhage (430) and intrace...

Dual-purpose barley and wheat production is a valuable resource to fill feed gaps grain production, but availability at drought heat stress conditions still not clearly studied. Two experiments were conducted semi-controlled green house determine biomass vegetative stages, chlorophyll content yield. Experiment 1 consists of four clipping treatments on wheat, i.e. one, two, three times un-clippi...

Orthogonal Frequency Division Multiplexing with Offset Quadrature Amplitude Modulation (OFDM/OQAM) signal has high peak-to-average power ratio (PAPR) problem. It not only affects the distortion in High Power Amplifier (HPA) but also results bit error (BER) degradation. In this paper an improved algorithm based on Clipping and Compressed Sensing (CS) is proposed. The transmitter uses clipping to...
