A Toolkit for Optimizing Fish Passage Barrier Mitigation Actions

Optimizing the removal of small fish passage barriers

Removing small artificial barriers that hinder upstream migrations of fish is a major problem in riparian habitat restoration. Because of budgetary limitations, it is necessary to prioritize barrier removal and repair decisions. These have usually been based on scoring and ranking procedures, which, although simple to use, can be very inefficient in terms of increasing the amount of accessible ...

hyp: A Toolkit for Representing, Manipulating, and Optimizing Hypergraphs

We present hyp, an open-source toolkit for the representation, manipulation, and optimization of weighted directed hypergraphs. hyp provides compose, project, invert functionality, k-best path algorithms, the inside and outside algorithms, and more. Finite-state machines are modeled as a special case of directed hypergraphs. hyp consists of a C++ API, as well as a command line tool, and is avai...

A collusion mitigation scheme for reputation systems

Reputation management systems are in wide-spread use to regulate collaborations in cooperative systems. Collusion is one of the most destructive malicious behaviors in which colluders seek to affect a reputation management system in an unfair manner. Many reputation systems are vulnerable to collusion, and some model-specific mitigation methods are proposed to combat collusion. Detection of col...

Protein dynamics and enzymatic chemical barrier passage.

After many decades of investigation, the manner in which enzymes increase the rate of chemical reactions, at times by a factor of 10(17) compared to the rate of the corresponding solution phase reaction, is still opaque. A topic of significant discussion in the literature of the past 5-10 years has been the importance of protein dynamics in this process. This Feature Article will discuss the au...
