Unipolarity of the Solar Magnetic Field in Equatorial Coronal Holes

The Astrophysical Journal
A study of the unbalanced magnetic polarity distribution of 70 coronal holes was performed. Data from the Helioseismic and Magnetic Imager were used to examine the photospheric line-of-sight magnetic field ( B _LOS ) beneath these coronal holes.

Sympatho‐Excitation in Pulmonary Hypertension: The Potential Role of Pulmonary Arterial Baroreceptors: An Acute Physiologic Intervention Study

Respirology, EarlyView.
Pulmonary arterial baroreceptors reflexively stimulate sympathetic nerve activity (SNA) in response to elevated pulmonary artery pressure and distension. In pulmonary hypertension patients, changes in muscle SNA were proportional to changes in pulmonary haemodynamics following nebulised iloprost.

Effect of Stimulus Duration on the Electrogustometric Threshold

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Electrogustometry (EGM)—the psychophysical measurement of human taste function by the application of weak electric currents to taste bud fields—has proved useful in clinical and research settings. Although EGM detection thresholds have been reported to be sensitive to stimulus duration, studies differ on this point and have not been ...

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

High Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.
