Enterprise portals collect and synthesise information from various systems to deliver personalised and highly relevant information to users. Enterprise portals’ design and applications are widely discussed in the literature; however, the implications of portal design in a global networked environment have barely been explored. This paper aims to highlight the challenges of enterprise portals fo...

This paper outlines a method to use (compressed) flipbooks of textures to represent portals in 3D models. A portal is a generalization of windows and doors. It connects two adjacent cells (or rooms). This method accelerates portal visibility culling by reducing the depth of portal sequences to one. Each portal of the current cell that is some distance away from the viewpoint is rendered as a te...

Portal vein tumor thrombus is a frequent, challenging complication in hepatocellular carcinoma. Hepatocellular carcinoma patients with portal vein tumor thrombus may show worse liver function, less treatment tolerance and worse prognosis than patients without portal vein tumor thrombus, and they may be at higher risk of comorbidity related to portal hypertension. Western and some Asian guidelin...

With the large volume of electronic portal images acquired and stringent time constraints, it is no longer feasible to follow the convention whereby the radiation oncologist reviews and approves or rejects all portals. For that purpose we have developed a portal image classifier based on the fuzzy k-nearest neighbour (k-NN) algorithm. Each portal image is represented by a feature vector that co...

Repair of the posterior superior labrum usually involves placing an anchor posterior to the biceps attachment through an anterior-superior or Wilmington portal. Access to the posterior-superior labrum can be accomplished by establishing a portal medial to the posterior viewing portal. The initial posterior arthroscopic viewing portal is established slightly lateral to a traditional position to ...

DNA enters the herpes simplex virus capsid by way of a ring-shaped structure called the portal. Each capsid contains a single portal, located at a unique capsid vertex, that is composed of 12 UL6 protein molecules. The position of the portal requires that capsid formation take place in such a way that a portal is incorporated into one of the 12 capsid vertices and excluded from all other locati...

Portal vein branching anomaly occurs due to aberration of normal anastomotic patterns and involution of vitelline veins during development of portal vein. Anatomical knowledge of portal vein and its branching pattern is important for hepatobiliary surgeon and gastrointestinal intervention radiologist. We are reporting a case of absence of portal vein bifurcation showing single main intrahepatic...

OBJECTIVE The objective of this study was to determine the sequential CT findings of controlled hepatocellular carcinoma (HCC) with main portal vein (MPV) thrombosis with the use of transcatheter arterial chemoembolization and additional intra-arterial cisplatin infusion. MATERIALS AND METHODS From January 2004 to September 2006, 138 patients with HCC invading MPV were referred to the angiogr...

Cirrhosis of the liver is by far the most common cause of portal hypertension in the western world. Portal hypertension is a frequent clinical syndrome, defined by a pathological increase in the portal venous pressure. When the portal pressure gradient (the difference between pressures in the portal and the inferior vena cava veins: normal value below 6 mmHg) increases above 10-12 mmHg, complic...

Introduction The 2012 National Strategy for Biosurveillance1 calls for improved integration, synchronization, and coordination of national biosurveillance activities and acknowledges the benefits of collective knowledge through sharing and receiving of biosurveillance information via strengthened partnerships amongst international, federal, state, local, tribal, territorial, private sector, non...
