We present the first polynomial-time approximation schemes (PTASes)
for the following subset-connectivity problems in edge-weighted graphs of
bounded genus: Steiner tree, low-connectivity survivable-network design,
and subset TSP. The schemes run...

Escape from parasites in their native range is one of many mechanisms that can contribute to the success of an invasive
species. Gnathiid isopods are blood-feeding ectoparasites that infest a wide range of fish hosts, mostly in coral reef...

A process-based forest growth model, 3-PG (Physiological Principles Predicting
Growth), parameterized with values of soil properties constrained by satellite-derived
estimates of maximum leaf area index (LAI[subscript max]), was run for...

We consider flow-structure interactions modeled by a modified wave equation coupled at an interface with equations of nonlinear elasticity. Both subsonic and supersonic flow velocities are treated with Neumann type flow conditions, and a novel...

Amplification was regarded, since the early days of quantum theory, as a mysterious ingredient that
endows quantum microstates with macroscopic consequences, key to the “collapse of the wave packet,”
and a way to avoid embarrassing problems...

OBJECTIVE: To establish a statewide network to detect, control, and prevent the spread of carbapenem-resistant Enterobacteriaceae (CRE)
in a region with a low incidence of CRE infection.
DESIGN: Implementation of the Drug Resistant Organism...

Easier access to X-ray microtomography (lCT) facilities has provided much new insight from
high-resolution imaging for various problems in porous media research. Pore space analysis with respect to
functional properties usually requires...

For the past six years in which overwintering mortality of honey bee colonies has been surveyed in the USA, estimates of colony loss have
fluctuated around one-third of the national population. Here we report on the losses for the 2012-2013...

Hop Pests and Their Control: A Report of the Control of the Hop Red Spider and Other Closely Related Problems During the Season of 1940 was written by H.E. Morrison (Assistant in Entomology) and J.D. Vertrees (Research Fellow for the Dow Chemical...

We construct uncountably many simply connected open
3-manifolds with genus one ends homeomorphic to the Cantor set.
Each constructed manifold has the property that any self homeomorphism of the manifold (which necessarily extends to a...

After contamination of soil in Japan due to the Fukushima Daiichi accident, there has been an increased interest in remediation of radiologically contaminated land. This study investigated the efficacy of a new biological remediation technology...

The influence of media size upon the effective removal
of organic waste from a liquid substrate was studied by the
use of three experimental trickling filters under a set
of uniform operating conditions. The range of experiments
involved hydraulic...

The Weather Radar Set An/CPS-9 at McCulloch Peak,
Oregon, provided data of changes in radar precipitation
echo patterns in the vicinity of Marys Peak. Echo heights
studied from data collected on 14 March 1963 averaged nearly
the same upwind,...

Data were taken, following irradiation exposure to
100r and 300r cumulative dose, on 89 rabbits of three
breeds that vary greatly in body size. Hematological,
intestinal motility, and ear vascularity examinations
were performed. Least square...
