Understanding resurgence and restlessness at calderas: insights from climatic vs post-climatic eruptive compositions with particular reference to Toba, Sumatra

Creator:: Bowers, Jade M., de Silva, Shanaka L., and Mucek, Adonara E.
Abstract:: Although calderas and the caldera cycle are well studied, the relationship between caldera-forming eruptions and post-caldera volcanism is poorly understood. The chemical characteristics of the erupted products suggest that two end member compositions are involved during resurgence: (1) remnant magma of similar composition to the magma of the climactic eruption;...

Universal interaction-driven gap in metallic carbon nanotubes

Creator:: Senger, Mitchell J., McCulley, Daniel R., Lotfizadeh, Neda, Deshpande, Vikram V., and Minot, Ethan D.
Abstract:: Suspended metallic carbon nanotubes (m-CNTs) exhibit a remarkably large transport gap that can exceed 100 meV. Both experiment and theory suggest that strong electron-electron interactions play a crucial role in generating this electronic structure. To further understand this strongly-interacting system, we have performed electronic measurements of suspended m-CNTs with known...

Dielectric Engineering Boosts the Efficiency of Carbon Nanotube Photodiodes

Creator:: Senger, Mitchell J., Kefayati, Ali, Bertoni, Andrea, Perebeinos, Vasili, and Minot, Ethan D.
Abstract:: Carbon nanotube (CNT) photodiodes are a promising system for high-efficiency photocurrent generation due to the strong Coulomb interactions that can drive carrier multiplication. If the Coulomb interactions are too strong, however, exciton formation can hamper photocurrent generation. Here, we explore, experimentally and theoretically, the effect of the environmental dielectric constant...

Two-phase flow regimes of condensing R-134a at low mass flux in rectangular microchannels

Creator:: Vanderputten, Michael A., Jacob, Tabeel A., Sattar, Maria, Ali, Nouman, and Fronk, Brian M.
Abstract:: Qualitative two-phase flow regime data are obtained from high-speed visualization of condensing flows of R-134a at mass fluxes from 75 to 150 kg m−2 s−1 and quality from 0.1 to 0.8 in square microchannels (DH = 0.84 mm) cooled from a single side. Superheated R-134a is distributed into multiple parallel microchannels and then partially condensed, using...

Evaluating the size and extent of paleolakes in central Tibet during the late Pleistocene

Creator:: Shi, Xuhua, Furlong, Kevin P., Kirby, Eric, Meng, Kai, Marrero, Shasta, Gosse, John, Wang, Erchie, and Phillips, Fred
Abstract:: Subhorizontal lake shorelines allow a geodynamic test of the size and extent of a hypothesized paleolake in central Tibet, the East Qiangtang Lake (EQL), during the last interglacial period (marine isotope stage (MIS) 5e). Reconstructions based on relict lake deposits suggest that the EQL would have been ~400 m deep...

eDNA as a tool for identifying freshwater species in sustainable forestry: A critical review and potential future applications

Creator:: Coble, Ashley A., Flinders, Camille A., Homyack, Jessica A., Penaluna, Brooke E., Cronn, Richard C., and Weitemier, Kevin
Abstract:: Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...

Measuring Anti-Müllerian Hormone Concentrations to Determine Reproductive Status in Female Rabbits

Creator:: Meeker, Alissa R.
Abstract:: There are over two million pet rabbits in the United States. Many rabbits are obtained as adults from pet stores and humane societies. Pet rabbit owners may elect to perform ovariohysterectomy (spay) surgeries on female rabbits to prevent unwanted pregnancies as well as to eliminate the possibility of reproductive disorders...

Estimating effects of arsenic exposure during pregnancy on perinatal outcomes in a Bangladeshi cohort

Creator:: Kile, Molly L., Cardenas, Andres, Rodrigues, Ema, Mazumdar, Maitreyi, Dobson, Christine, Golam, Mostofa, Quamruzzaman, Quazi, Rahman, Mahmudar, and Christiani, David C.
Abstract:: BACKGROUND: The relationship between arsenic and birth weight is not well understood. OBJECTIVE: To evaluate the causal relationship between prenatal arsenic exposure and birth weight considering the potential mediation effects of gestational age (GA) and maternal weight gain (MWG) during pregnancy using structural equation models (SEMs). METHODS: A prospectively enrolled...

Abstract:: The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...

The Viability of Container-Based Sanitation as a Tool for Sanitation Coverage in Urban Haiti

Creator:: VanRiper, Froggi Ramona
Abstract:: Haiti is far from achieving the UN goal of sanitation access for all; 20% Haitians have no sanitation access, and less than 0.1% of urban excreta is safely managed. Container-Based Sanitation (CBS) may be a key tool for achieving equitable sanitation coverage in Haiti’s cities. CBS is a sanitation strategy...
