Quantifying gravity wave momentum fluxes with mesosphere temperature mappers and correlative instrumentation

An Advanced Mesosphere Temperature Mapper and other instruments at the Arctic Lidar Observatory for Middle Atmosphere Research in Norway (69.3°N) and at Logan and Bear Lake Observatory in Utah (42°N) are used to demonstrate a...

Atmospheric Gravity Waves
Atmospheric predictability from sub-seasonal to seasonal time scales and climate variability are both influenced critically by gravity waves (GW). The quality of regional and global numerical models relies on thorough...
Joint analysis of gravitational-wave and electromagnetic data of mergers

On 2017 August 17, Advanced LIGO and Virgo observed GW170817, the first gravitational-wave (GW) signal from a binary neutron star merger. It was followed by a short-duration gamma-ray burst, GRB 170817A, and by a non-thermal...

Sensitivity of Mountain Wave Drag Estimates on Separation Methods and Proposed Improvements

Internal gravity waves (GWs) are ubiquitous in the atmosphere, making significant contributions to the mesoscale motions. Since the majority of their spectrum is unresolved in global circulation models, their effects need to...

Stratospheric Gravity Waves as a Proxy for Hurricane Intensification

We conducted simulations with a 4-km resolution for Hurricane Joaquin in 2015 using the weather research and forecast (WRF) model. The model data are used to study stratospheric gravity waves (GWs) generated by the hurricane...

Maximum tension
JD Barrow, GW Gibbons
Feb 17, 2015
We discuss various examples and ramifications of the conjecture that there exists a maximum force (or tension) in general relativistic systems. We contrast this situation with that in Newtonian gravity, where no maximum force...
Prospects for policy advances in science and technology in the Gulf Arab States
Science, technology, engineering and mathematics (STEM) policies in the Gulf Arab States are as diverse as the individual economies and political processes that characterize its member states. During the past decade, a number of...
Anatomy of a Slow Merger
C Hamilton, RR Rafikov
Nov 02, 2022
Abstract The dozens of compact object mergers detected by LIGO/Virgo raise a key theoretical question: how do initially wide binaries shrink sufficiently quickly that they are able...
Probing the speed of gravity with LVK, LISA, and joint observations
Ian Harry, Johannes Noller
Nov 09, 2022
AbstractTheories of dark energy that affect the speed of gravitational waves $$c_{\textrm{GW}}$$
Fetal eye movements on magnetic resonance imaging.
OBJECTIVES: Eye movements are the physical expression of upper fetal brainstem function. Our aim was to identify and differentiate specific types of fetal eye movement patterns using dynamic MRI sequences. Their occurrence as...
Cognitive impairment in Parkinson's disease
BACKGROUND: The quality of life (QoL) of informal caregivers of people with Parkinson's disease (PD) (PwP) can be affected by the caring role. Because of cognitive symptoms and diminished activities of daily living, in addition...
Evolution of genome fragility enables microbial division of labor.
Division of labor can evolve when social groups benefit from the functional specialization of its members. Recently, a novel means of coordinating the division of labor was found in the antibiotic-producing bacterium...
