NAND flash memory based storage devices use Flash Translation Layer (FTL) to translate logical addresses of I/O requests to corresponding flash memory addresses. Mobile storage devices typically have RAM with constrained size, thus lack in memory to keep the whole mapping table. Therefore, mapping tables are partially retrieved from NAND flash on demand, causing random-read performance degradat...

In the hierarchical phrase based (HPB) translation model, in addition to hierarchical phrase pairs extracted from bi-text, glue rules are used to perform serial combination of phrases. However, this basic method for combining phrases is not sufficient for phrase reordering. In this paper, we extend the HPB model with maximum entropy based bracketing transduction grammar (BTG), which provides co...

Zeolites as solid acid materials have played important roles in industrial catalysis. The attempts to obtain new zeolite framework structures and related chemical compositions never stopped, may expand the application thereof. Using renewable bioderived molecules starting feedstocks would be of great help building a more circular carbon cycle. However, zeolites only shown limited efficiency con...

Hiperplasia Prostática Benigna (HPB) é a doença mais comum entre homens idosos com sintomas do trato urinário inferior (MCVARY, 2006). Sobre sua fisiopatologia, bem conhecido e relatado o papel função dos andrógenos fatores de crescimento no início da progressão HPB. Além desses componentes, inflamação; principalmente crônica, vem ganhando destaque como possível fator importante, influente prós...

BACKGROUND Patients with prolonged length of hospital stay (LOS) not only increase their risks of nosocomial infections but also deny other patients access to inpatient care. Hepatobiliary (HPB) malignancies have some of highest incidences in East and Southeast Asia and the management of patients undergoing HPB surgeries have yet to be standardized. With improved neurosurgery techniques for int...

OBJECTIVE Dysphagia aortica describes swallowing difficulty caused by external compression from a tortuous or aneurysmal aorta. We present 5 cases in which dysphagia to solids accompanied a localised high pressure barrier (HPB) on manometry suggestive of dysphagia aortica, and explore other investigation modalities useful to confirm the diagnosis. METHODS Four females and 1 male with a median...

Histamine-producing bacteria (HPB) such as Photobacterium phosphoreum and Raoultella planticola possess histidine decarboxylase (HDC), which converts histidine into histamine. Histamine fish poisoning (HFP) is attributable to the ingestion of fish containing high levels of histamine produced by HPB. Because freezing greatly decreases the histamine-producing ability of HPB, especially of P. phos...

Purpose. To investigate clinical results on bleb-related endophthalmitis (BRE) after trabeculectomy treated with pars plana vitrectomy (PPV) and to evaluate influence factors for visual prognosis. Methods. Investigating medical records retrospectively, BRE was defined as an endophthalmitis induced by bleb infection. A total of 2018 eyes of 1225 patients who had trabeculectomy between December 2...
