Freezing of gait is a complex, heterogeneous, and highly variable phenomenon whose pathophysiology and neural signature remains enigmatic. Evidence suggests that freezing is associated with impairments across cognitive, motor and affective domains; however, most research to date has focused on investigating one axis of freezing of gait in isolation. This has led to inconsistent findings and a r...
Considerable efforts have been made to identify changes of brain synaptic plasticity associated with fear conditioning. However, for both clinical applications and our fundamental understanding of memory processes, it appears also necessary to investigate synaptic plasticity related to extinction. We previously showed that extinction of freezing to a tone conditioned stimulus (CS; previously pa...
Other recent laboratory measurements for aqueous ammonium sulfate and sulfuric acid solutions show considerable variability in freezing point temperatures – much more than is predicted by the widely-used translated melting-point curve (TMPC) idea of Koop et al. (2000). This paper reports on results from laboratory measurements of homogeneous ice nucleation in aqueous droplets containing two com...
Abstract. Soil freeze–thaw processes play a fundamental role in the hydrology, geomorphology, ecology, thermodynamics, and soil chemistry of cold regions' landscapes. In understanding these processes, temperature is used as proxy to represent partitioning ice water content via freezing characteristic curve (SFCC). This mathematical construct relates specific for particular soil. SFCCs depend on...
