The movement of unconsolidated materials near the Earth’s surface is often driven by disturbances that occur at a range of spatial and temporal scales. The nature of these disturbances ranges from highly variable, such as tree turnover, to periodic and predictable, such as frost heave or creep. To explore the effect of probabilistic disturbances on surface processes, we formulated a granular cr...

Five biopsy specimens of morphologically normal human breast tissues, obtained from the margins of five benign human breast tumors, were processed into slices (4.0 x 4.0 x 0.1 mm) and transplanted s.c. dorsally (eight to ten slices/mouse) into forty-three 6- to 8-week-old female BALB/c athymic nude mice. Each individual human breast tissue specimen was transplanted into seven to ten mice. After...

BACKGROUND The purpose of this study is to investigate the clinical effectiveness of staging radioactive particle implantation guided by computed tomography (CT) and fiber-optic bronchoscopy in treating cancerous large airway stenosis. METHODS A total of 102 patients were included; 57 had undergone staging radioactive particle implantation guided by CT and fiber bronchoscopy and 45 did not. P...

Lead (Pb) is a known nephrotoxic element. Recently we have proved that subcellular Ca2+ redistribution is involved in Pb-induced apoptosis in primary cultures of rat proximal tubular (rPT) cells, but the underlying mechanism remains to be elucidated. Firstly, data showed that Pb triggers endoplasmic reticulum (ER) stress response in rPT cells, as evidenced by the elevations of ER stress markers...

Residual pleural thickening (RPT) develops in some patients after metapneumonic pleural effusion (MPE). Our aim was to identify factors that predict the development of RPT by retrospectively analyzing patients with MPE secondary to bacterial pneumonia in our practice from 1992 through April 1997. Patients were assigned to groups based on the presence or not of RPT (> 10 mm) three months or more...

Lead (Pb) is a known nephrotoxicant that causes damage to proximal tubular cells. Autophagy has an important protective role in various renal injuries, but the role of autophagy in Pb-elicited nephrotoxicity remains largely unknown. In this study, Pb promoted the accumulation of autophagosomes in primary rat proximal tubular (rPT) cells, and subsequent findings revealed that this autophagosome ...

This article presents a novel approach for a real-time person tracking system based on particle filters that use different visual streams. Due to the difficulty of detecting a person from a top view, a new architecture is presented that integrates different vision streams by means of a Sigma-Pi network. A short-term memory mechanism enhances the tracking robustness. Experimental results show th...

Penelitian ini bertujuan untuk menguji secara empiris pengaruh mekanisme corporate governance terhadap Related Party Transaction. Mekanisme Corporate Governance terbagi menjadi variabel Kepemilikan Institusional, Manajerial, Komisaris Independen, Komite Audit. Variabel Transaction ditentukan berdasarkan Disclosure dan Besaran RPT yang diukur dengan RPTAL. Data digunakan dalam penelitian merupak...
