Rules, regulations, and payment policies were changed to allow extensive use of telecommunications technology in lieu of in-person clinical visits to protect health care personnel and patients throughout the country from the risk of disease trans...

We resolve a 1983 question of Serre by constructing curves with many points of every genus over every finite field. More precisely, we show that for every prime power q there is a positive constant cq with the following property: for every integer g ≥ 0, there is a genus-g curve over Fq with at least cqg rational points over Fq. Moreover, we show that there exists a positive constant d such tha...

A self-con rming equilibrium is the answer to the following question: what are the possible limiting outcomes of purposeful interactions among a collection of adaptive agents, each of whom averages past data to approximate moments of the conditional probability distributions of interest? If outcomes converge, a Law of Large Numbers implies that agents' beliefs about conditional moments become c...

Even when provided with feedback after every movement, adaptation levels off before biases are completely removed. Incomplete adaptation has recently been attributed to forgetting: the adaptation is already partially forgotten by the time the next movement is made. Here we test whether this idea is correct. If so, the final level of adaptation is determined by a balance between learning and for...

This paper presents a system for a shared virtual experience which was developed within a student project. The main idea is to have two or more persons at different locations, who can interact with each other in the same virtual environment. In order to realize this idea every person is motion-captured and wears a head-mounted display (HMD). The virtual environment is rendered with the Unity ga...
