L'CO/LFIR Relations with CO Rotational Ladders of Galaxies Across the Herschel SPIRE Archive

We present a catalog of all CO (J=4-3 through J=13-12)), [CI], [NII] lines available from extragalactic spectra from the Herschel SPIRE Fourier Transform Spectrometer (FTS) archive combined with observations of the low-J CO lines from the literature and from the Arizona Radio Observatory. This work examines the relationships between LFIR, L'CO, and LCO/LCO(1-0). We also present a new method for estimating probability distribution functions (PDFs) from marginal signal-to-noise ratio Herschel} FTS spectra, which takes into account the instrumental "ringing" and the resulting highly correlated nature of the spectra. The slopes of log(LFIR) vs. log(L'CO) are linear for all mid- to high-J CO lines and slightly sublinear if restricted to (U)LIRGs. The mid- to high-J CO luminosity relative to CO J=1-0 increases with increasing LFIR, indicating higher excitement of the molecular gas, though these ratios do not exceed ~ 180. For a given bin in LFIR, the luminosities relative to CO J=1-0 remain relatively flat from J=6-5 through J=13-12, across three orders of magnitude of LFIR. A single component theoretical photon-dominated region (PDR) model cannot match these flat SLED shapes, though combinations of PDR models with mechanical heating added qualitatively match the shapes, indicating the need for further comprehensive modeling of the excitation processes of warm molecular gas in nearby galaxies.Comment: 17 pages, 4 figures (including appendix), accepted by ApJ.

Systemic enzyme therapy in chronic venous disease: a review

Chronic venous disease (CVD), a sequel of venous insufficiency, has great medical and socioeconomic impact. Varicose veins and venous ulcer are amongst its commonest manifestations. In CVD, incompetent valves, weakened vascular walls, venous hypertension and increased permeability of venous walls lead to the release of proinflammatory mediators like tumor necrosis factor (TNF)-α, interleukin (IL)-1β, reactive oxygen species (R.O.S.), and reactive nitrogen species (R.N.S.) in the venous milieu. Pharmacotherapy with nonsteroidal anti-inflammatory drugs (NSAIDs) is often used to relieve pain caused by venous disease. However, there is a need for therapies that target the microcirculatory disorders and act on chronic inflammatory processes. Systemic enzyme therapy (SET), with orally administered combination of proteolytic enzymes- trypsin, bromelain, and flavonoid rutoside, has been used since decades for their anti-inflammatory, analgesic, anti-edematous, antithrombotic and antioxidant properties. This review discusses the various relevant pharmacodynamic properties demonstrated by the ingredients, followed by clinical studies of SET, which have demonstrated benefit in both subjective and objective parameters. These studies indicate that SET has good efficacy, tolerability and holds great promise to improve the quality of life of a patient with CVD.  

A Three Dimensional Lattice of Ion Traps

We propose an ion trap configuration such that individual traps can be stacked together in a three dimensional simple cubic arrangement. The isolated trap as well as the extended array of ion traps are characterized for different locations in the lattice, illustrating the robustness of the lattice of traps concept. Ease in the addressing of ions at each lattice site, individually or simultaneously, makes this system naturally suitable for a number of experiments. Application of this trap to precision spectroscopy, quantum information processing and the study of few particle interacting system are discussed.Comment: 4 pages, 4 Figures.

Social Ecological Climate Resilience Project - 2016

Prepared for: North Central Climate Science Center, Fort Collins, Colorado.February 2017.Includes bibliographical references.Climate change is already having impacts on nature, ecosystem services and people in southwestern Colorado and is likely to further alter our natural landscapes in the coming decades. Understanding the potential changes and developing adaptation strategies can help ensure that natural landscapes and human communities remain healthy in the face of a changing climate. An interdisciplinary team consisting of social, ecological and climate scientists developed an innovative climate planning framework and worked with the Social‐Ecological Climate Resilience Project (SECR) and other stakeholders in Colorado’s San Juan River watershed to develop adaptation strategies for two significant landscapes, pinyon juniper woodlands and seeps, springs, and wetland resources under three climate scenarios between 2035 and 2050. This report summarizes the planning framework and results for the pinyon‐juniper landscape (the seeps, springs and wetlands results will be provided separately). This framework can be utilized to develop strategies for other landscapes at local, state, and national scales. Diagrams, narrative scenarios, and maps that depict climate scenarios and the social‐ecological responses help us portray the climate impact in the face of an uncertain future. Interviews and focus group workshops with agency staff and stakeholders who are users of public lands identified several important opportunities to improve the adaptation planning process for developing strategies that meet both social and ecological needs. Planning techniques that include or directly relate to specific resources, such as water and forage, or to activities, such as recreation or grazing, provide avenues for engaging diverse stakeholders into the process. Utilizing the scenarios to understand the impacts to our social and ecological landscapes, three overarching landscape‐scale adaptation strategies were developed. Each of these strategies has a suite of potential actions required to reach a desired future condition. The three key strategies are: 1) identify and protect persistent ecosystems as refugia, 2) proactively manage for resilience, and 3) accept, assist, and allow for transformation in non‐climate refugia sites. If the framework and strategies from this project are adopted by the local community, including land managers, owners, and users, the climate change impacts can be reduced, allowing for a more sustainable human and natural landscape

Mid-J CO Emission in Nearby Seyfert Galaxies

We study for the first time the complete sub-millimeter spectra (450 GHz to 1550 GHz) of a sample of nearby active galaxies observed with the SPIRE Fourier Transform Spectrometer (SPIRE/FTS) onboard Herschel. The CO ladder (from Jup = 4 to 12) is the most prominent spectral feature in this range. These CO lines probe warm molecular gas that can be heated by ultraviolet photons, shocks, or X-rays originated in the active galactic nucleus or in young star-forming regions. In these proceedings we investigate the physical origin of the CO emission using the averaged CO spectral line energy distribution (SLED) of six Seyfert galaxies. We use a radiative transfer model assuming an isothermal homogeneous medium to estimate the molecular gas conditions. We also compare this CO SLED with the predictions of photon and X-ray dominated region (PDR and XDR) models.Comment: Proceedings of the Torus Workshop 2012 held at the University of Texas at San Antonio, 5-7 December 2012.
