Persistent, long‐lived, stationary sites of excessive mantle melting are called hotspots. Hotspots leave volcanic trails on lithospheric plates passing across them. The global constellation of fixed hotspots thus forms a convenient frame of reference for plate motions, through the orientations and age distributions of volcanic trails left by these melting...

The discovery of a brilliant-blue color upon the introduction of Mn³⁺
to the trigonal-bipyramidal (TBP) sites in YInO₃ has led to a search for other hosts
for Mn³⁺ in TBP coordination. An obvious choice would be YAlO₃. This compound,
which has only been prepared through a citrate precursor route, has...

We demonstrate a four-channel on-chip true-time-delay module based on a photonic crystal waveguide array. Using the photonic crystal taper to minimize the coupling loss, the delay lines with 1-3 mm long photonic crystal waveguides can operate up to a group index n(g) similar to ~23 without significant loss. The large...
Severe infection by the endemic myxozoan parasite, Ceratonova (synonym, Ceratomyxa) shasta, has been associated with declines in and impaired recovery efforts of populations of fall-run Chinook Salmon Oncorhynchus tshawytscha in the Klamath River, California. The parasite has a complex life cycle involving a polychaete worm host as well as a...
Forest surveys provide critical information for many diverse interests. Data are often collected from samples, and from these samples, maps of resources and estimates of aerial totals or averages are required. In this paper, two approaches for mapping and estimating totals; the spatial linear model (SLM) and k-NN (k-Nearest Neighbor)...
Production of Kþ mesons in charged-current νμ interactions on plastic scintillator (CH) is measured using MINERvA exposed to the low-energy NuMI beam at Fermilab. Timing information is used to isolate a sample of 885 charged-current events containing a stopping Kþ which decays at rest. The differential cross section in Kþ...
We consider issues of equality and efficiency in two different school funding systems - a state-level system in Michigan and a foundation system in Ohio. Unlike Ohio, the Michigan system restricts districts from generating property or income tax revenue to fund operating expenditures. In both states, districts fund capital expenditures...
We present new age determinations, derived from ⁴⁰Ar–³⁹Ar incremental heating experiments, for basaltic lava flows from the Mandla lobe, located on the eastern margin of the main Deccan volcanic province, some ~ 1000 km from the Western Ghats escarpment. The most reliable estimates of crystallization ages come from 5 plateau...
The nonexponential phosphorescence decay of a highly folded form of poly-riboadenylic acid (poly rA) with noncovalently bound dye is explained by a novel application of a well-known theory of electronic excitation transfer based on the Förster mechanism. This theory, originally used to describe singlet-singlet energy transfer from donor molecules to...
Internal waves of depression were observed propagating
along‐shelf and into northern Monterey Bay, California
(CA) on the inner shelf. These waves had amplitudes
approximately equal to the thermocline depth (∼4 m), and
were unstable to shear and mix the thermocline. Isopycnal
gradient spectra showed that the wave packets lead to...
Recent literature has investigated whether the welfare gains from environmental taxation are
larger or smaller in a second-best setting than in a first-best setting. This question has mainly
been addressed indirectly, by asking whether the second-best optimal environmental tax is higher
or lower than the first-best Pigouvian rate. Even this...
For more than 35 years we have known that the accuracy of DNA replication is controlled in
large part by the relative concentrations of the four canonical deoxyribonucleoside 5'-triphosphates (dNTPs) at the replisome. Since this field was last reviewed, about eight years ago,
there has been increased understanding of the...
In macromolecular X-ray crystallography, typical data sets have substantial multiplicity. This can be used to calculate the consistency of repeated measurements and thereby assess data quality. Recently, the properties of a correlation coefficient, CC[subscript 1/2], that can be used for this purpose were characterized and it was shown that CC[subscript...
Bulk aerodynamic formulas are applied to meteorological data from low-altitude aircraft flights to observational estimates of the subgrid enhancement of momentum, sensible heat, and latent heat the atmospheric–oceanic boundary in light wind, fair weather conditions during TOGA COARE Global Atmosphere Coupled Ocean–Atmosphere Response Experiment). Here, subgrid enhancement the contributions of...
The activation method has been used to measure the cross sections for radiative capture of neutrons by all isotopes of stable Ce (mass numbers 136, 138, 140, and 142). Both the thermal cross sections and the resonance integrals have been determined from separate irradiations with thermal and epithermal neutrons, wherever...
Intelligent air traffic flow management is one of the fundamental challenges facing the Federal Aviation Administration (FAA) today. FAA estimates put weather, routing decisions and airport condition induced delays at 1,682,700 h in 2007 (FAA OPSNET Data, US Department of Transportation website, http://www.faa.gov/data_statistics/), resulting in a staggering economic loss of...
Observations of the scale-dependent turbulent fluxes, variances, and the bulk transfer parameterization for sensible heat above, within, and beneath a tall closed Douglas-fir canopy in very weak winds are examined. The daytime sub-canopy vertical velocity spectra exhibit a double-peak structure with peaks at timescales of 0.8 s and 51.2 s....
