More intense issues such as racing age, medication, track surfaces, and breeding can be better addressed in subsequent articles after the nature of the horse and the implications of racetrack confinement are addressed.
Coombs said senior military officers tracked his confinement because they feared bad publicity.
"The use of solitary tracks directly with the rise in mass incarceration," says Jean Casella, co-director of Solitary Watch, a watchdog group that tracks solitary confinement in the US.
Runway confinements are the next category.
For velocity quantification and tracking in 2D confinement, cell nuclei were stained with 200 ng/ml of Hoechst for 15 min at 37°C and cells were imaged every 2 min using a Zeiss AxioObserver microscope equipped with a 10× objective.
The agency does not track the cost of solitary confinement, but experts say the practice can triple the cost and can be hundreds of times more expensive than alternatives like using electronic ankle bracelets.
The former N.F.L lineman Dana Stubblefield received two years of probation; the former Olympic cyclist Tammy Thomas was given five years of probation and six months of home confinement; and the track coach Trevor Graham received five years of probation and a year of home confinement.
"If ICE is no longer tracking the use of solitary confinement or no longer requiring that people who are in mental health crisis are checked on every 15 minutes, that can kill," said Carl Takei, an attorney with the American Civil Liberties Union's National Prison Project.
Tracks were then quantified for number, speed, length, duration, displacement and confinement ratio (defined as the quotient of track length and track displacement).
The radius of confinement (rconf) of a track is defined to be the magnitude of the radius of the smallest circle that encloses all points in that track.
Tracking each eigenmode, the instability lines under confinement effects are derived in closed forms.
