Inbreeding depression is a widespread phenomenon of central importance to agriculture, medicine, conservation biology and evolutionary biology. Although the population genetic principles of inbreeding depression are well understood, we know little about its functional genomic causes. To provide insight into the molecular interplay between intrinsic stress responses, inbreeding depression and te...

Aim This research study explored the lived experiences of adults diagnosed with Coronary Artery Disease (CAD) when exposed to a prolonged period of extreme cold. Design This research study utilized descriptive qualitative research design. Methods Face-to-face interview sessions with audio recording were conducted. There were 30 informants who participated in the study. Descriptive phenomeno...

The LHC cryodipoles are composed of an evacuated cryostat and a cold mass, which is cooled by superfluid helium at 1.9 K. To obey constraints imposed by beam dynamics the particle beams must be centered within the mechanical axis of the dipole with a sub-millimeter accuracy. This requires in turn that the relative displacements between the cryostat and the cold mass must be monitored with accur...

We carried out an ALMA survey of 15 confirmed or candidate low-mass (<0.2 M ) members of the TW Hya Association (TWA) with the goal of detecting molecular gas in the form of CO emission, as well as of providing constraints on continuum emission due to cold dust. Our targets have spectral types of M4-L0 and hence represent the extreme low end of the TWA’s mass function. Our ALMA survey has yield...

[1] Observations show that the upper 2 km of the subtropical North Atlantic Ocean cooled throughout 2010 and remained cold until at least December 2011. We show that these cold anomalies are partly driven by anomalous air-sea exchange during the cold winters of 2009/2010 and 2010/2011 and, more surprisingly, by extreme interannual variability in the ocean's northward heat transport at 26.5°N. T...

During an unusual cold-water event in January 2010, reefs along the Florida Reef Tract suffered extensive coral mortality, especially in shallow reef habitats in close proximity to shore and with connections to coastal bays. The threatened staghorn coral, Acropora cervicornis, is the focus of propagation and restoration activities in Florida and one of the species that exhibited high susceptibi...

We monitored behavioral responses of cold-acclimated hatchling painted turtles (Chrysemys picta ) indigenous to Nebraska and hatchling snapping turtles (Chelydra serpentina ) indigenous to Nebraska and Arkansas during cooling (0.18C/min) to temperatures as low as ÿ198C. All turtles made exploratory movements during cooling and locomotion occurred at temperatures as low as ÿ2 to ÿ48C, but C. pic...

The cold extremes along with record snowfalls in North America (NA) have attracted great concern for decades. In this study, we select 23 wintertime northwestern NA (NWNA) from 1981 to 2018 and find a significant weakening trend of their integrated yearly intensities. Strong northerlies advections over NWNA associated the events are driven by intensified southward Beaufort anticyclone at lower ...

Infant rats cycle rapidly between periods of high muscle tone (indicative of wakefulness) and periods of atonia (indicative of sleep). Here, the influence of air temperature on sleep in 8-day-old rats was examined by testing pups at thermoneutrality (35 degrees C) and during moderate (28 degrees C) and extreme (20 degrees C) cold challenge; also, pups were tested 1, 4, and 8 hr after infusion o...
