Little is known about mixing in the abyssal equatorial oceans in spite of its inferred importance for upwelling dense water. Here we present full-depth microstructure turbulence profiles obtained in the equatorial Pacific that show evidence for intense wind-generated abyssal mixing. Mixing was intensified over the bottom 700 m where the...

Modeling of slope flow circulations in idealized axisymmetric craters is used to understand (1) the large surface pressure amplitude observed in Gale Crater by the Rover Environmental Monitoring Station and (2) the shallow convective boundary layer (CBL) suggested by Curiosity imagery. Air temperatures vary within craters with greater amplitudes than...

The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Continental precipitation not routed to the oceans as runoff returns to the atmosphere
as evapotranspiration. Partitioning this evapotranspiration flux into interception, transpiration,
soil evaporation, and surface water evaporation is difficult using traditional hydrological
methods yet critical for understanding the water cycle and linked ecological processes. We
combined two large-scale flux-partitioning...

OBJECTIVES:
The specific objectives of the present study were to 1) evaluate the rate of hemorrhage-related complications across a large number of feline pedicle tie procedures and 2) evaluate for a difference in surgical time between traditional pedicle double-ligation and pedicle tie procedures.
METHODS:
In the initial phase of the...
PURPOSE/OBJECTIVE: Disability identity involves affirming one’s status as a person with a
disability and incorporating this group membership into one’s identity. It is associated with well-being
in populations of people with disabilities, but its relationship with depression and anxiety
in multiple sclerosis (MS) has yet to be examined. It was...
We have measured voltage-current characteristics for YBa₂Cu₃O₇ thin films in magnetic fields from 5
T to ambient, including some in the millitesla range. In all cases, the resistivity —current density isotherms
can be separated into two classes: those which exhibit upward curvature, and have constant
resistivity at low currents, and...
Silica bodies in short cell epidermal leaf cells of the Early Cretaceous Programinis laminatus (Poales) in Burmese amber are characterized. The great majority are rondels and elongated quadrates aligned horizontally in relation to the leaf axis. Rondel types include circular, elliptical, oblong, long and short forms. Quadrate types include short...
The piezoelectric fatigue behavior of Pb-free ceramics based on solid solutions of Bi(Zn₀.₅Ti₀.₅)O₃-(Bi₀.5K₀.₅)TiO₃-(Bi₀.₅Na₀.₅)TiO₃ was characterized at 50 kV/cm after 10⁶ bipolar cycles. Ferroelectric compositions containing 2.5% Bi(Zn₀.₅Ti₀.₅)O₃ exhibited only minor losses in maximum strain (~10%). In compositions with 5% Bi(Zn₀.₅Ti₀.₅)O₃ that exhibit large electric field-induced strains, the electromechanical strain actually...
SnS is a potential earth-abundant photovoltaic (PV) material. Employing both theory and experiment to assess the PV relevant properties of SnS, we clarify on whether SnS has an indirect or direct band gap and what is the minority carrier effective mass as a function of the film orientation. SnS has...
