Spectroscopic Interpretation: The High Vibrations of CDBrClF

We extract the dynamics implicit in an algebraic fitted model Hamiltonian for the deuterium chromophore's vibrational motion in the molecule CDBrClF. The original model has 4 degrees of freedom, three positions and one representing interbond couplings. A conserved polyad allows in a semiclassical approach the reduction to 3 degrees of freedom. For most quantum states we can identify the underlying motion that when quantized gives the said state. Most of the classifications, identifications and assignments are done by visual inspection of the already available wave function semiclassically transformed from the number representation to a representation on the reduced dimension toroidal configuration space corresponding to the classical action and angle variables. The concentration of the wave function density to lower dimensional subsets centered on idealized simple lower dimensional organizing structures and the behavior of the phase along such organizing centers already reveals the atomic motion. Extremely little computational work is needed.Comment: 23 pages, 6 figures. Accepted for publication in J. Chem. Phy

Local Ecological Knowledge and Chronic Disease in the Fort McDermitt Paiute-Shoshone Tribe

The relationship between chronic disease and traditional knowledge is little understood within indigenous populations of North America. I hypothesize that individuals with higher levels of local ecological knowledge (LEK) will observe lower frequencies of chronic disease and better health outcomes. Health data will be compared to LEK within a subsample (n=31) of individuals residing within the Fort McDermitt Paiute-Shoshone Reservation in Nevada and Oregon. Individual level health data on diabetes mellitus (type 2), pre-diabetes, BMI, chronic heart disease, and hypertension is measured directly by the investigator or self-reported. LEK level data is taken from expert interviews, subject interviews, surveys, and direct observation. LEK data is comprised of species identification, acquisition, and utilization. LEK data regards an individual’s level of species knowledge, identification, utilization, acquisition, and preparation of wild floral and faunal species incorporated within the diet and medicinal remedies. The results show that individuals with higher levels of LEK display lower occurrence of the chronic diseases stated previously and their predictors. These results have implications that the promotion of traditional culture within indigenous societies alleviates the negative health effects of chronic disease. It can further be argued that the adaptive strategies associated with LEK provide a prescriptive analog for health behaviors within greater American society

Self-Consistent Measurement and State Tomography of an Exchange-Only Spin Qubit

We report initialization, complete electrical control, and single-shot readout of an exchange-only spin qubit. Full control via the exchange interaction is fast, yielding a demonstrated 75 qubit rotations in under 2 ns. Measurement and state tomography are performed using a maximum-likelihood estimator method, allowing decoherence, leakage out of the qubit state space, and measurement fidelity to be quantified. The methods developed here are generally applicable to systems with state leakage, noisy measurements, and non-orthogonal control axes.Comment: contains Supplementary Informatio

Coherent photonuclear reactions for isotope transmutation

Coherent photonuclear isotope transmutation (CPIT) produces exclusively radioactive isotopes (RIs) by coherent photonuclear reactions via E1 giant resonances. Photons to be used are medium energy photons produced by laser photons backscattered off GeV electrons. The cross sections are as large as 0.2 - 0.6 b, being independent of individual nuclides. A large fraction of photons is effectively used for the photonuclear reactions, while the scattered GeV electrons remain in the storage ring to be re-used. CPIT with medium energy photons provides specific/desired RIs with the high rate and the high density for nuclear science, molecular biology and for nuclear medicines.Comment: 8 pages, 2 figure

Rare-earth coordination polymers with multimodal luminescence on the nano-, micro-, and milli-second time scales

We present a coordination polymer based on rare-earth metal centers and carboxylated 4,4′-diphenyl-2,2′-bipyridine ligands. We investigate Y$^{3+}$, Lu$^{3+}$, Eu$^{3+}$, and a statistical mixture of Y$^{3+}$ with Eu$^{3+}$ as metal centers. When Y$^{3+}$ or Lu$^{3+}$ is exclusively present in the coordination polymer, biluminescence from the ligand is observed: violet emission from the singlet state (417 nm, 0.9 ns lifetime) and orange emission from the triplet state (585 nm, 76 ms (Y$^{3+}$) and 31 ms (Lu$^{3+}$)). When Eu$^{3+}$ is present in a statistical mixture with Y$^{3+}$, red emission from the Eu$^{3+}$ (611 nm, ∼500μs) is observed in addition to the ligand emissions. We demonstrate that this multi-mode emission is enabled by the immobility of singlet and triplet states on the ligand. Eu$^{3+}$ only receives energy from adjacent ligands. Meanwhile, in the broad inhomogeneous distribution of ligand energies, higher energy states favor singlet emission, whereas faster intersystem crossing in the more stabilized ligands enhances their contribution to triplet emission
