Grassland managements can affect carbon (C) and nitrogen (N) storage in grassland ecosystems with consequent feedbacks to climate change. We investigated the impacts of compound fertilization and clipping on grass biomass, plant and soil (0-20 cm depth) C, N storage, plant and soil C: N ratios, soil microbial activity and diversity, and C, N sequestration rates in grassland in situ in the Natio...

Aims Land use management affects plant carbon (C) supply and soil environments and hence alters soil nitrogen (N) dynamics, with consequent feedbacks to terrestrial ecosystem productivity. The objective of this study was to better identify mechanisms by which land-use management (clipping and shading) regulates soil N in a tallgrass prairie, OK, USA. Methods We conducted 1-year clipping and sha...

BACKGROUND AND PURPOSE The effects of aneurysm treatment modality (clipping or coiling) on the incidence of cerebral vasospasm and infarction after subarachnoid hemorrhage have not been clearly defined. We hypothesized that there may be a difference in angiographic and clinical vasospasm, cerebral infarction, and clinical outcome between patients undergoing clipping compared to coiling. METHO...

Multi-layer interleave-division multiple access (IDM/IDMA) inherently exhibits a large peak-to-average power ratio (PAPR). Correspondingly, the power amplifier has to operate with a large back-off, which reduces the power efficiency. Clipping at the transmitter side is an efficient and simple method to reduce the PAPR, but causes nonlinear in-band distortions and sometimes out-of-band radiation...

In an Orthogonal Frequency Division Multiplexing (OFDM) systems, the Peak to Average power Ratio (PAR) is high. The clipping signal scheme is a useful and simple method to reduce the PAR. However, it introduces additional noise that degrades the systems performance. We propose an oversampling scheme to deal with the received signal in order to reduce the clipping noise by using finite impulse r...

Objective: Pre-operative endoscopic clipping for determining the resection line in patients with early gastric cancer (EGC) has been used safely, and its efficacy has been demonstrated. However, the optimal timing of endoscopic clipping for determining the resection line in EGC patients undergoing laparoscopy-assisted distal gastrectomy (LADG) has not been investigated. Methods: A retrospective...

BACKGROUND AND PURPOSE Age might differentially affect outcomes in patients treated for unruptured cerebral aneurysms with surgical clipping versus endovascular coil therapy. We evaluated a large administrative database to determine the effect of age on outcomes in patients treated for unruptured cerebral aneurysm. METHODS Using the National Inpatient Sample, we evaluated morbidity (discharge...

Highly advanced optical equipment enables endoscopic surgery to be performed in neurosurgery. We developed an angle-type rigid endoscope having an angled shaft, and has performed endoscope-assisted surgery in neck clipping of 50 cerebral aneurysms. Anatomical study concerning the perforating branch was made through a pterional approach using 3 cadavers. By using endoscope, we can observe the po...
