RECOVERING 21CM MONOPOLE SIGNALS WITHOUT SMOOTHNESS

Recovering 21cm Monopole Signals Without Smoothness

We expect the monopole signal at the lowest frequencies below $100,$MHz to be composed to two components: the deep Rayleigh-Jeans tail of the cosmic microwave background and two distinct features: the dark ages trough at $sim 17,$MHz and the cosmic dawn trough at $sim 75,$Mhz.These are hidden under orders of magnitude brighter foregrounds whose emi

From theory to practice: translating the concept of cognitive resilience to novel therapeutic targets that maintain cognition in aging adults

While the concept of cognitive resilience is well-established it has not been defined in a way that can be measured.This has been an impediment to studying its underlying biology and to developing instruments for its clinical assessment.This perspective highlights recent work that has quantified the expression of cortical proteins associated with c
