Identification of neural firing patterns, frequency and temporal coding mechanisms in individual aortic baroreceptors

open access: yesFrontiers in Computational Neuroscience, 2015
In rabbit depressor nerve fibers, an on-off firing pattern, period-1 firing, and integer multiple firing with quiescent state were observed as the static pressure level was increased. A bursting pattern with bursts at the systolic phase of blood pressure,

Coronal plasmas on the sun and nearby stars [PDF]

open access: yes
The current understanding of the quiescent, or non-flaring, microwave emission from solar active regions is summarized. The thermal radiation mechanisms that account for most of the quiescent emission is reviewed, while it is also pointed out that ...

The X-ray quiescence of Swift J195509.6+261406 (GRB 070610): an optical bursting X-ray binary? [PDF]

open access: yes, 2011
We report on a 63ks Chandra observation of the X-ray transient Swift J195509.6+261406 discovered as the afterglow of what was first believed to be a long duration Gamma-Ray Burst (GRB 070610).

Opportunities for Multiscale Pattern Modulation with Temporally Arrested Breath Figures

open access: yesAdvanced Materials Interfaces, EarlyView.
This works presents the temporally arrested breath figure methodology and its opportunities for pattern modulation. Through thermodynamic and photochemical phase change handles, this method uses drop‐wise condensation as a dynamic template for fast, accessible and scalable micropatterning.

Pattern Formation in Non‐Equilibrium Architected Materials

open access: yesAdvanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Herpesviral lytic gene functions render the viral genome susceptible to novel editing by CRISPR/Cas9

open access: yeseLife, 2019
Herpes simplex virus (HSV) establishes lifelong latent infection and can cause serious human disease, but current antiviral therapies target lytic but not latent infection.

Quiescent current sensor circuits in digital VLSI CMOS testing

open access: yesElectronics Letters, 1990
Many integrated circuit processing defects may cause changes in the value of the quiescent power supply current. Not all of these changes are detectable using classical functional testing techniques. Testing techniques based on the quiescent power supply current inspection have been reported to be efficient in the detection of a wide set of well known ...

Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,

A “Wait-and-See” Approach to Quiescent Single-System Langerhans Cell Histiocytosis to Spare Children From Chemotherapy

open access: yesFrontiers in Pediatrics, 2020
Background: Langerhans Cell Histiocytosis (LCH) is a childhood disorder of histiocytes that is generally treated with systemic chemotherapy. Spontaneous resolution has been previously reported in Single System LCH (SS-LCH), which is less aggressive than ...
