Modeling soft robots that move on surfaces is challenging from a variety of perspectives. A recent formulation by Bergou et al. rod theory exploits new developments in discrete differential geometry offers an attractive, numerically efficient avenue to help overcome some these challenges. Their example elastic theory. In this article, we consider planar version al.'s and, with the works Lagrange's equations motion for constrained systems particles, show how it can be used model are composed...

Motivated by problems of pursuit and evasion in coordinated multi-agent systems, we present a model pursuit, herding for three agents: single pursuer, e.g. bear, chooses target point along the line connecting two evaders, mother caribou her calf, each choose strategy that trades off herding. The is based on feedback control constant speed steered particles plane. Dynamics over reduced set shape variables are defined. Parallel-motion equilibria studied, with stability analysis analytic...
Abstract Major disturbances can temporarily remove factors that otherwise constrain population abundance and distribution. During such windows of relaxed top‐down and/or bottom‐up control, ungulate populations grow rapidly, eventually leading to resource depletion density‐dependent expansion into less‐preferred habitats. Although many studies have explored the demographic outcomes ecological impacts these processes, fewer examined individual‐level mechanisms by which they occur. We...

A wide variety of highly substituted lactam containing peptidomimetic scaffolds are prepared by solid-phase synthesis from a single, versatile class resin-bound aldehyde intermediates (1). These include monocyclics 3, bicyclics 4, tricyclics 5, and tetracyclics 6. The key intermediate 1 is readily synthesized natural or unnatural α-amino acids. synthetic procedures permit the construction large diversity substitution patterns for ready use in combinatorial chemistry. In every case, release...

Remote amide bonds in simple N-acyl amino acid or peptide derivatives 1 can be surprisingly unstable hydrolytically, affording, solution, variable amounts of 3 under mild acidic conditions, such as trifluoroacetic acid/water mixtures at room temperature. This observation has important implications for the synthesis this class compounds, which includes N-terminal-acylated peptides.
