Local large deviation principles are established in dimensions d \ 3 for the super Brownian motion with random immigration X + t , where the immigration rate is governed by the trajectory of another super-Brownian motion +. The speed function is t for d \ 4 and t 1/2 for d=3, compared with the existing results, the interesting phenomenon happened in d=4… (More)
Moderate deviation principles are established in dimensions d ≥ 3 for the super Brownian motion with random immigration X t , where the immigration rate is governed by the trajectory of another super-Brownian motion. It fills in the gap between the central limit theorem and the large deviation principles for this model which obtained by Hong & Li (1999) and… (More)
The occupation time of a super Brownian motion with immigration governed by the trajectory of another super-Brownian motion is considered, a large deviation principle is obtained for dimension d ≥ 7.
BACKGROUND Microsurgery is a common treatment of brainstem tumors. However, misdirection, vascular damage, nerves injuries, paralysis, even death are all well-known complications, and the risk of adverse events is more likely in less experienced operators. This study was aimed to validate the accuracy of multimodal neuronavigation during microsurgery… (More)
OBJECTIVE To explore and analyze the influencing factors of facial nerve function retainment after microsurgery resection of acoustic neurinoma. METHODS Retrospective analysis of our hospital 105 acoustic neuroma cases from October, 2006 to January 2012, in the group all patients were treated with suboccipital sigmoid sinus approach to acoustic neuroma… (More)
Malignant peripheral nerve sheath tumors (MPNSTs) are very rare soft tissue sarcomas, usually arising from somatic soft tissues or peripheral nerves. Primary MPNST of the cerebellopontine angle is extremely rare, with only a single case reported so far. Here, we report an unusual case of MPNST in cerebellopontine angle in a 25-year-old man presented with… (More)
OBJECTIVE We performed a meta-analysis of reported series of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) for non-communicating hydrocephalus to determine whether comparisons between the outcomes in ETV and VPS approaches are valid. METHODS Online databases were searched for articles reporting quantifiable outcome data… (More)
A quenched central limit theorem is derived for the super-Brownian motion with super-Brownian immigration, in dimension d ≥ 4. At the critical dimension d = 4, the quenched and annealed fluctuations are of the same order but are not equal.
