Flowers In A Wasteland 2

This piece represents abstracted flowers thriving in a wasteland. Though the flowers are difficult to make out, the viewer can still distinguish each flower through the hazy blur of a landscape

Substance Use Disorder Treatment Decision Aid for Adults in Chittenden County Vermont

Substance Abuse Disorders (SUDs) are a prevalent public health concern in both the national and local arena resulting in millions of dollars in pubic health costs and loss of life. Navigating the treatment options available in Chittenden County can be time consuming, difficult, and delay treatment. In order to help guide adult patients and their families in Chittenden County along their journey towards recovery from SUDs, a treatment decision aid was developed for choosing the right level of care.https://scholarworks.uvm.edu/fmclerk/1500/thumbnail.jp

Nordic Himalaya Research Network (NHRN) First Inaugural Meeting

On May 7, 2018, the inaugural meeting for the newly established Nordic Himalaya Research Network was held at the Department of Cross-Cultural and Regional Studies at the University of Copenhagen

Algebraic Structure of Lepton and Quark Flavor Invariants and CP Violation

Lepton and quark flavor invariants are studied, both in the Standard Model with a dimension five Majorana neutrino mass operator, and in the seesaw model. The ring of invariants in the lepton sector is highly non-trivial, with non-linear relations among the basic invariants. The invariants are classified for the Standard Model with two and three generations, and for the seesaw model with two generations, and the Hilbert series is computed. The seesaw model with three generations proved computationally too difficult for a complete solution. We give an invariant definition of the CP-violating angle theta in the electroweak sector

Baryon Exotics in the Quark Model, the Skyrme Model and QCD

We identify the quantum numbers of baryon exotics in the Quark Model, the Skyrme Model and QCD, and show that they agree for arbitrary colors and flavors. We define exoticness, E, which can be used to classify the states. The exotic baryons include the recently discovered qqqq qbar pentaquarks (E=1), as well as exotic baryons with additional q qbar pairs (E >=1). The mass formula for non-exotic and exotic baryons is given as an expansion in 1/N, and allows one to relate the moment of inertia of the Skyrme soliton to the mass of a constituent quark

A Spatially Explicit Census Reveals Population Structure and Recruitment Patterns for a Narrowly Endemic Pine, Pinus torreyana

We conducted a census of the rare pine, Pinus torreyana ssp.  torreyana, in order to determine: a) what is the population size and is it stable, growing or declining; b) what is the spatial variation in population structure; c) what is the spatial patterning of trees in different life stages; and, d) what environmental factors are related to seedling recruitment?  Trees were classified into four stages classes: adult (160 cm tall with cones); sub-adult (160 cm without cones); saplings (30-160 cm), and seedlings (30 cm).  Stem diameter was measured for adults and sub-adults, and height for saplings and seedlings.  Stands were defined by spatial clustering of the tree map.  Univariate and bivariate point pattern analyses were used to explore spatial patterns for adult and juvenile trees and identify potential stand development processes such as density dependence, dispersal limitations, and patchy recruitment.  Logistic regression was used to analyze seedling establishment and survival in relation to environmental variables derived from digital maps.  We expected to find little or no recruitment based on earlier studies.  Instead, 5422 trees were mapped and measured, and tree size had “reverse J-shaped†distribution suggestive of a recruiting population.  However, population structure was variable among stands.  The predominant spatial pattern detected for adult and juvenile trees was clustering at lag distances 10 m.  Bivariate pattern analysis did not suggest repulsion between adult and juvenile size classes.  Seedlings tended to be found close to adults and on certain soil types.  Taken together, this suggests that the clustered patterns resulting from patchy recruitment and survival of juveniles persist over time.
