Cutting Down Damages Awards in Timber Trespass Cases

The Alaska Supreme Court recently heard two cases addressing damages awards for timber trespass claims. Both cases, Wiersum v. Harder and Chung v. Park , emphasized the difficulty of obtaining restoration damages and the close scrutiny given to the size of the damages award itself. This Note explores the history of timber trespass and the current method by which courts determine the appropriate damages award. The Note also proposes a possible alternative to the current reticence toward restoration damages in which the plaintiff may elect to receive restoration damages but would be required to use those damages to restore their trees

Impact of tether cutting on onboard navigation during the Tethered Satellite Mission-1

The first Tethered Satellite System mission (TSS-1) is manifested for Shuttle Flight STS-44 in January of 1991. The TSS mission presents a new challenge to engineers, requiring advanced guidance, navigation and control concepts. Current NASA flight rules require that the navigational state of the Orbiter at deorbit burn be known to an accuracy of 20 nautical miles. Response of the Shuttle crew to this contingency may involve cutting the tether prior to a complete retrieval. The degradation of the navigational state accuracy as modelled by Shuttle navigation system is examined. Responses to the loss of communication scenario are proposed for two cases. The first case examines navigational performance during a nominal attitude profile. The second case is identical to the first, with the inclusion of modelled tether electrodynamical forces. Comparisons of trajectories propagated from the onboard navigational state vector and a reference ephemeris state vector were performed, with the tether cut simulated at various points during the mission. Additionally, updates to the onboard navigational state via ground uplinks were provided prior to the assumed loss of communication. Through these comparisons, the onboard navigation state error was determined. Alternative responses result from efforts to minimize this error during the various phases of TSS-1 deployment. These results demonstrated existing NASA flight rules could be violated by cutting the tether, and suggests reponses to a loss of communications contingency to maintain a more accurate navigational state

Green Bank Telescope Observations of 3He+: HII Regions

During the era of primordial nucleosynthesis the light elements 2H, 3He, 4He, and 7Li were produced in significant amounts and these abundances have since been modified primarily by stars. Observations of 3He+ in HII regions located throughout the Milky Way disk reveal very little variation in the 3He/H abundance ratio---the "3He Plateau"---indicating that the net effect of 3He production in stars is negligible. This is in contrast to much higher 3He/H abundance ratios found in some planetary nebulae. This discrepancy is known as the "3He Problem". Stellar evolution models that include thermohaline mixing can resolve the 3He Problem by drastically reducing the net 3He production in most stars. These models predict a small negative 3He/H abundance gradient across the Galactic disk. Here we use the Green Bank Telescope to observe 3He+ in five HII regions with high accuracy to confirm the predictions of stellar and Galactic chemical evolution models that include thermohaline mixing. We detect 3He+ in all the sources and derive the 3He+/H+ abundance ratio using model HII regions and the numerical radiative transfer code NEBULA. The over 35 radio recombination lines (RRLs) that are simultaneously observed, together with the 3He+ transition provide stringent constraints for these models. We apply an ionization correction using observations of 4He RRLs. We determine a 3He/H abundance gradient as a function of Galactocentric radius of -0.116 +/- 0.022 x 10-5, consistent with stellar evolution models including thermohaline mixing that predict a small net contribution of 3He from solar mass stars.Comment: Accepted for publication in A

Reparable Harm: Assessing and Addressing Disparities Faced by Boys and Men of Color in California

The California Endowment commissioned this report to highlight the most glaring inequities in socioeconomics, health, safety, and education faced by African-American and Latino men and boys in the state. In addition to presenting the statistics on these indicators, the authors outline a framework for addressing the disparities at the individual, community, and macro levels

Band Distributions for Quantum Chaos on the Torus

Band distributions (BDs) are introduced describing quantization in a toral phase space. A BD is the uniform average of an eigenstate phase-space probability distribution over a band of toral boundary conditions. A general explicit expression for the Wigner BD is obtained. It is shown that the Wigner functions for {\em all} of the band eigenstates can be reproduced from the Wigner BD. Also, BDs are shown to be closer to classical distributions than eigenstate distributions. Generalized BDs, associated with sets of adjacent bands, are used to extend in a natural way the Chern-index characterization of the classical-quantum correspondence on the torus to arbitrary rational values of the scaled Planck constant.Comment: 12 REVTEX page

Does a Simple Lattice Protein Exhibit Self-Organized Criticality?

There are many unanswered questions when it comes to protein folding. These questions are interesting because the tertiary structure of proteins determines its functionality in living organisms. How do proteins consistently reach their final tertiary structure from the primary sequence of amino acids? What explains the complexity of tertiary structures? Our research uses a simple hydrophobic-polar lattice-bound computational model to investigate self-organized criticality as a possible mechanism for generating complexity in protein folding and protein tertiary structures
