We report vibrational information of both the first electronically excited state and the ground
cationic state of jet-cooled triphenylene via the techniques of resonantly enhanced multiphoton
ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The first excited
electronic state S₁ of the neutral molecule is of A₁' symmetry and...
We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[a]pyrene (BaP) via resonantly enhanced multiphoton ionization (REMPI). Our analysis concentrates on the vibrational modes of the first excited state (S₁) and those of the ground cationic state (D₀). Similar to pyrene, another peri-condensed polycyclic aromatic hydrocarbon we have investigated, the...
We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[h]quinoline (BhQ) via resonantly enhanced multiphoton ionization (REMPI) through the first electronically excited state S₁. From the simulated REMPI spectra with and without Herzberg–Teller coupling, we conclude that vibronic coupling plays a minor but observable role in the electronic excitation to...
Joseph Reddeford Walker conducted
a party of men across the Sierra Nevada to the
Pacific coast of California in 1833. Previous
interpretations of the portion of the route
from Humboldt Sink, Nevada, to the San Joaquin
River, California, are not satisfactory. A
body of descriptions of the terrain traversed
exists...
Just as Pirsig’s (Pirsig, R.M. 1974. Zen and the Art of Motorcycle Maintenance. William Morrow and Company, New York. 412pp.) account of his motorcycle adventure explores the dichotomy of holistic and reductionistic philosophies, so too does a short course in chainsaw safety and tree felling incorporate these seemingly disparate viewpoints...

The zebrafish (Danio rerio) is emerging as a new important species for studying brain mechanisms and its deficits. Focusing on selected CNS disorders (brain cancer, epilepsy and anxiety) and using them as examples, we discuss the value of zebrafish models in translational neuroscience, and their contribution to neuroimaging, circuit-level and...
Cytokinins are a group of plant hormones mediating cell division and
differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly
metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion
have been studied extensively. Zeatin metabolic enzymes may be utilized in studying the
regulation of...
The Horseshoe Gulch area includes 16 square miles in the
Eastern Paleozoic Belt of the Klamath Mountains geologic province
north of Callahan, California. Fossiliferous Late Ordovician and
Silurian limestones and unfossiliferous greywackes, arkoses, shales,
mudstones, schists, and phyllites, and other terrigenous clastic
rocks are exposed in a broad fault zone...

We tested closure between in situ radiometric and absorption coefficient measurements by using a nearly backscattering-independent remote-sensing reflectance model that employs the remote-sensing reflectance at three wavelengths. We show that only a small error is introduced into the closure model when the proper functional relationships of f/Q and the backscattering...

This study investigated how lidar-derived vegetation indices, disturbance history from Landsat time series (LTS)
imagery, plot location accuracy, and plot size influenced accuracy of statistical spatial models (nearest-neighbor
imputation maps) of forest vegetation composition and structure. Nearest-neighbor (NN) imputation maps were
developed for 539,000 ha in the central Oregon Cascades,...

Tree invasions have been documented throughout Northern Hemisphere high elevation meadows, as well as globally in many grass and forb-dominated ecosystems. Tree invasions are often associated with large-scale changes in climate or disturbance regimes, but are fundamentally driven by regeneration processes influenced by interactions between climatic, topographic, and biotic factors...

Forests play a critical role sequestering atmospheric carbon dioxide, partially offsetting greenhouse gas emissions, and thereby mitigating climate change. Forest management, natural disturbances, and the fate of carbon in wood products strongly influence carbon sequestration and emissions in the forest sector. Government policies, carbon offset and trading programs, and sustainable...

Forest carbon (C) density varies tremendously across space due to the inherent heterogeneity of forest ecosystems. Variation of forest C density is especially pronounced in mountainous terrain, where environmental gradients are compressed and vary at multiple spatial scales. Additionally, the influence of environmental gradients may vary with forest age and...

Nonlinear optical processes can be described as multiphoton scattering events in terms of high order perturbation theory. The standard procedure for quantitative calculation of high order terms is to impose a steady state condition on the perturbative radiation fields. In the present work, this condition will be lifted, and explicit...
