A Note on Flips in Diagonal Rectangulations

Rectangulations are partitions of a square into axis-aligned rectangles. A number of results provide bijections between combinatorial equivalence classes of rectangulations and families of pattern-avoiding permutations. Other results deal with local changes involving a single edge of a rectangulation, referred to as flips, edge rotations, or edge pivoting. Such operations induce a graph on equivalence classes of rectangulations, related to so-called flip graphs on triangulations and other families of geometric partitions. In this note, we consider a family of flip operations on the equivalence classes of diagonal rectangulations, and their interpretation as transpositions in the associated Baxter permutations, avoiding the vincular patterns { 3{14}2, 2{41}3 }. This complements results from Law and Reading (JCTA, 2012) and provides a complete characterization of flip operations on diagonal rectangulations, in both geometric and combinatorial terms

Oral Health Intervention: A Multifaceted Approach to Improve Oral Health Care during Pregnancy

Introduction: Early Childhood Caries (ECC) is the most common chronic disease of childhood Mothers’ oral health status is a strong predictor of the oral health status of their children 2009: Vermont spends $2.7 million treating children ages 0-5 with Early Childhood Caries 2012: Vermont lifts the$495 Medicaid cap on reimbursement for a woman’s dental care during pregnancy and up to 60 days after delivery American College of Obstetrics and Gynecology (ACOG) Guidelines on prenatal dental care are published 2013: 74% of surveyed Vermont providers treating pregnant women are unaware of the Medicaid change 82% of these providers are not using guidelines to assess oral health during pregnancy Objective: To improve prenatal dental referral rates from obstetric providers by facilitating Vermont-specific implementation of ACOG guidelineshttps://scholarworks.uvm.edu/comphp_gallery/1212/thumbnail.jp

Optimizing ethanol and bioelectricity production in sugarcane biorefineries in Brazil

In sugarcane biorefineries, the lignocellulosic portion of the sugarcane biomass (i.e. bagasse and cane trash) can be used as fuel for electricity production and/or feedstock for second generation (2G) ethanol. This study presents a techno-economic analysis of upgraded sugarcane biorefineries in Brazil, aiming at utilizing surplus bagasse and cane trash for electricity and/or ethanol production. The study investigates the trade-off on sugarcane biomass use for energy production: bioelectricity versus 2G ethanol production. The BeWhere mixed integer and spatially explicit model is used for evaluating the choice of technological options. Different scenarios are developed to find the optimal utilization of sugarcane biomass. The study finds that energy prices, type of electricity substituted, biofuel support and carbon tax, investment costs, and conversion efficiencies are the major factors influencing the technological choice. At the existing market and technological conditions applied in the upgraded biorefineries, 300 PJy^12G ethanol could be optimally produced and exported to the EU, which corresponds to 2.5% of total transport fuel demand in the EU. This study provides a methodological framework on how to optimize the alternative use of agricultural residues and industrial co-products for energy production in agro-industrie
