Neural net simulations of human event parsing are described. A recurrent net was used to simulate data collected from human subjects watching short videotaped event sequences. In one simulation, the net was trained on one-half of a taped sequence with the other half of the sequence being used to test transfer performance. In another simulation, the net was(More)
How can the components of visual comprehension be characterized as brain activity? Making sense of a dynamic visual world involves perceiving streams of activity as discrete units such as eating breakfast or walking the dog. In order to parse activity into distinct events, the brain relies on both the perceptual (bottom-up) data available in the stimulus as(More)
Scale-free networks (SFN) arise from simple growth processes, which can encourage efficient, centralized and fault tolerant communication (1). Recently its been shown that stable network hub structure is governed by a phase transition at exponents (>2.0) causing a dramatic change in network structure including a loss of global connectivity, an increasing(More)

Creating new scaffolds for cells is critical to the development of new tissue engineering techniques. In this work, the synthesis of new polypeptide systems is discussed. These systems are intended for the formation of hydrogels which can then be used as cell substrates. Attempts at using the clickable synthetic polypeptide poly(ypropargyl L-glutamate)(More)
Background: Heart failure (HF) is the primary cause of hospitalizations and readmissions to a hospital within 30 days of initial discharge. In 2010 HF cost an estimated $39.2 billion in health care services, lost productivity and medications. Optimizing outpatient care is vital to effectively manage this patient population. Objective: The purpose of this(More)
