Ocean Energy: Using the Ocean's Tides, Waves, and Heat to Generate Electricity [PDF]

open access: yes, 2006
Key facts: - The oceans' tides, waves, current, and heat can be used to generate electricity. These resources are renewable, because the moon's gravity drives tides, and winds create waves.

Aqueous Lithium Hydroxide Chemistry Based on Hierarchically Assembled Hydrogenated Borophene/Cobalt‐Nickel Compounds for Rechargeable High‐Performance Supercapattery

open access: yesAdvanced Energy Materials, EarlyView.
Aqueous lithium‐ion storage has been demonstrated using a hierarchically assembled hydrogenated borophene/cobalt‐nickel compound as a supercapattery electrode. Reducible hydrogenated borophene generates undercoordinated oxygen, which is redox‐active for lithiation and hydrogenation during the discharging process following the lithium hydroxide ...

On the orbit of the short-period exoplanet WASP-19b

open access: yes, 2011
WASP-19b has the shortest orbital period of any known exoplanet, orbiting at only 1.2 times the Roche tidal radius. By observing the Rossiter-McLaughlin effect we show that WASP-19b's orbit is aligned, with lambda = 4.6 +/- 5.2 degrees.

The Short Rotation Period of Hi'iaka, Haumea's Largest Satellite [PDF]

open access: yes, 2016
Hi'iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysis, we have identified the rotation period of Hi'iaka to be ~9.8 hrs ...

Climate Change Agricultural Comparative Advantage and the US Trade Balance

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

Health disparities in chronic liver disease

open access: yesHepatology, EarlyView., 2022
Abstract The syndemic of hazardous alcohol consumption, opioid use, and obesity has led to important changes in liver disease epidemiology that have exacerbated health disparities. Health disparities occur when plausibly avoidable health differences are experienced by socially disadvantaged populations.

Tidal Evolution of Close-in Extra-Solar Planets

open access: yes, 2008
The distribution of eccentricities e of extra-solar planets with semi-major axes a > 0.2 AU is very uniform, and values for e are relatively large, averaging 0.3 and broadly distributed up to near 1.

Laparoscopic Colorectal Surgery in the Era of Robotics: Evolution, Eclipse, or Equilibrium?

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Minimally invasive colorectal surgery has undergone a remarkable transformation over the past three decades. Laparoscopy, once viewed with skepticism, is now firmly established as a standard approach, supported by robust randomized trials demonstrating oncologic safety and improved recovery compared to open surgery.
