On the Ubiquity and Physical Nature of Fe ix 17.1 nm Moss
The Astrophysical JournalThe spongy Fe ix 17.1 nm fine structure known as “moss” was first detected inside active region (AR) plages and has been widely interpreted as representing the transition region of the overlying hot coronal loops.

Can Thermal Nonequilibrium Explain Coronal Loops? [PDF]
, 2010 Any successful model of coronal loops must explain a number of observed properties. For warm (approx. 1 MK) loops, these include: 1. excess density, 2. flat temperature profile, 3. super-hydrostatic scale height, 4. unstructured intensity profile, and 5.

Advanced Science, EarlyView.RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

Spatiotemporal Low First Ionization Potential Abundance: A Catalyst for Coronal Condensation
The Astrophysical JournalRadiative losses play a critical role in the cooling of plasmas. When chromospheric plasma is sufficiently heated, it can flow into coronal loops, which subsequently cool down due to radiation. From observations, we infer that this cooling does not occur

The Astrophysical Journal, 2002 A controversy over the temperature distribution of coronal loops has arisen recently because different investigators using different techniques have obtained very different answers. Analysis of Solar and Heliospheric Observatory (SOHO) Extreme ultraviolet Imaging Telescope (EIT) and Transition Region and Coronal Explorer (TRACE) data using narrowband ...

Advanced Science, EarlyView.Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

Hypothalamic POMC Neurons Gate the Fear‐Feeding Trade‐Off
Advanced Science, EarlyView.Hungry animals must continually arbitrate between feeding and defensive behaviors when confronted with potential threats. We show that hypothalamic POMC neurons engage CRH‐expressing stress circuits and downstream hormonal responses to coordinate this behavioral selection between competing behaviors.
