A Survey for Satellites of Venus

open access: yes, 2009
We present a systematic survey for satellites of Venus using the Baade-Magellan 6.5 meter telescope and IMACS wide-field CCD imager at Las Campanas observatory in Chile.

The prognostic value of the Dandel's index in patients undergoing tricuspid transcatheter edge‐to‐edge repair

open access: yesEuropean Journal of Heart Failure, EarlyView.
Load adaptation indices and concepts. An adapted RV in response to overload increases wall thickness to normalize wall stress and preserve function and morphology. If hemodynamic overload is sustained, it can progress to a maladaptive state and lead eventually to heart failure. CI, cardiac index; Ees, ventricular elastance; Ea, arterial elastance; MPAP,

On the sources of the night side ionosphere of Venus

open access: yesGeofísica Internacional, 1978
Se presenta una descripción general de las características de la ionósfera nocturna en Venus y del medio magnético y plasmático en su estela. Se sugiere que el carácter variable de la ionósfera nocturna, es debido en parte, a condiciones de asimetría y ...

Regional tectonic analysis of Venus equatorial highlands and comparison with Earth-based Magellan radar images [PDF]

open access: yes
Research on regional tectonic analysis of Venus equatorial highlands and comparison with earth-based and Magellan radar images is presented. Over the past two years, the tectonic analysis of Venus performed centered on global properties of the planet, in

Anomalous CuCrP2S6/WSe2 interface enabled two‐dimensional programmable homojunction for self‐powered photodetection and complex optoelectronic logics

open access: yesInfoMat, EarlyView.
Ferroelectric materials hold great potential for modulating two‐dimensional (2D) materials to achieve electrically tunable homojunctions (ETH). Here, we introduce a novel 2D ETH device based on the anomalous interfacial effect between 2D layered ferroelectric CuCrP2S6 and ambipolar WSe2.

Five foundational tools for managing metadata from the USDA Long‐Term Agroecosystem Research (LTAR) Network

open access: yesJournal of Environmental Quality, EarlyView.
Abstract The United States Department of Agriculture Long‐Term Agroecosystem Research (LTAR) Network comprises 19 sites and has collectively produced nearly one petabyte of data. Data include time‐series measurements, remotely sensed imagery, and high‐throughput environmental data from field and laboratory instrumentation.
