A linearized baroclinic, spectral-in-time tidal inverse model has been developed for assimilation of surface currents from coast-based high-frequency (HF) radars. Representer functions obtained as a part of the generalized inverse solution show that for superinertial flows information from the surface velocity measurements propagates to depth along wave characteristics, allowing internal...
Statistical hypothesis testing has been widely criticized by ecologists in recent
years. I review some of the more persistent criticisms of P values and argue that most stem
from misunderstandings or incorrect interpretations, rather than from intrinsic shortcomings
of the P value. I show that P values are intimately linked...
The olfactory bulb contains the first synaptic relay in the olfactory pathway, the sensory system in which odorants are detected enabling these chemical stimuli to be transformed into electrical signals and, ultimately, the perception of odor. Acid-sensing ion channels (ASICs), a family of proton-gated cation channels, are widely expressed in...
