We study the percolation properties of graph partitioning on random regular graphs with N vertices of degree k. Optimal graph partitioning is directly related to optimal attack and immunization of complex networks. We find that for any partitioning process (even if nonoptimal) that partitions the graph into essentially equal sized connected components (clusters), the system undergoes a percolat...

The atmospheric oxidation of aromatic compounds is an important source of secondary organic aerosol (SOA) in urban areas. The oxidation of aromatics depends strongly on the levels of nitrogen oxides (NOx). However, details of the mechanisms by which oxidation occurs have only recently been elucidated. Xu et al. (2015) developed an updated version of the gas-phase Caltech Atmospheric Chemistry M...

For autonomous artificial decision-makers to solve realistic tasks, they need to deal with searching through large state and action spaces under time pressure. We study the problem of planning in such domains and show how structured representations of the environment’s dynamics can help partition the action space into a set of equivalence classes at run time. The partitioned action space is the...

Aqueous two-phase systems allow for the unequal distribution of proteins and other molecules in water-rich solutions containing phase separating polymers or surfactants. One approach to improve the partitioning properties of recombinant proteins is to produce the proteins as fused to certain peptide tags. However, the rational design of such tags has proven difficult since it involves a comprom...

Lightweight, age-hardenable aluminum alloys are attracting increasing attention as a means to reduce vehicle mass and improve fuel economy. To accelerate the adoption of these alloys, knowledge of the complex precipitation processes that underlie their primary strengthening mechanism is essential. Here we employ a combination of atom-probe tomography (APT), differential scanning calorimetry (DS...

In this paper, we investigate the optimal assignment problem of cells in PCS (Personal Communication Service) to switches in a wireless ATM network. Given cells and switches on an ATM network (whose locations are fixed and known), the problem is grouping cells into clusters and assigning these clusters to the switches in an optimum manner. This problem is modeled as a complex integer programmin...

Lipid analogues carrying three nitrilotriacetic acid (tris-NTA) head groups were developed for the selective targeting of His-tagged proteins into liquid ordered (lo ) or liquid disordered (ld ) lipid phases. Strong partitioning into the lo phase of His-tagged proteins bound to tris-NTA conjugated to saturated alkyl chains (tris-NTA DODA) was achieved, while tris-NTA conjugated to an unsaturate...
