It is now generally recognized that sensor-fusion is the best approach to the accurate construction of environmentmaps by a sensor-equippedmobile robot. Typically, range data collectedwith a range sensor is combined with the reflectance data obtained from one or more cameras mounted on the robot. In much of the past work on sensor fusion in hierarchical approaches to map construction, the fusio...

This paper is a discussion of the relationship between learning and forgetting. An analysis of the economics of learning is carried out and it is argued that knowledge can sometimes have a negative value. A series of experiments involving a program which learns to traverse state spaces is described. It is shown that most of the knowledge acquired is of negative value even though it is correct a...

Despite the wide range of resources that traverse social networks, social exchange research has focused on only a narrow subset. Notably, prior social exchange research has not considered resources like inforesources

Strava is a popular GPS-based cycling application. Using data gathered from this application, I predict the duration of time used by particular riders at specific times to traverse a 2-mile route along Mission Bay in San

Dupilumab blocks the shared receptor component of IL-4/IL-13, key and central drivers type 2 inflammation. In patients with asthma or CRSwNP, a transient increase in eosinophils was observed dupilumab treatment which declined over time rarely clinical consequence. The effect on blood assessed across indications. Median (95% CI) percent change from baseline measured dupilumab-treated uncontrolle...

Planetary surface mobility has to date been limited to benign locations. If rover systems could be developed for more challenging terrain, e.g., sloped and irregularly featured areas, then planetary science opportunities would be greatly expanded. We have in the last several years carried out a related program of R&D that involves new concepts in reconfigurable mobility and on-board adaptive co...

Plasmodium sporozoites are deposited in the host skin by Anopheles mosquitoes. The parasites migrate from the dermis to the liver, where they invade hepatocytes through a moving junction (MJ) to form a replicative parasitophorous vacuole (PV). Malaria sporozoites need to traverse cells during progression through host tissues, a process requiring parasite perforin-like protein 1 (PLP1). We find ...
