Simultaneous mesoscopic and two-photon imaging of neuronal activity in cortical circuits. [PDF]

open access: yes, 2020
Spontaneous and sensory-evoked activity propagates across varying spatial scales in the mammalian cortex, but technical challenges have limited conceptual links between the function of local neuronal circuits and brain-wide network dynamics. We present a

Flexible conformable hydrophobized surfaces for turbulent flow drag reduction [PDF]

open access: yes, 2015
In recent years extensive work has been focused onto using superhydrophobic surfaces for drag reduction applications. Superhydrophobic surfaces retain a gas layer, called a plastron, when submerged underwater in the Cassie-Baxter state with water in ...

Myocardial perfusion mapping with intra‐arterial spin labeling: Optimization of the labeling efficiency

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Intra‐arterial spin labeling (iASL) applies a labeling pulse from a transmit coil at the tip of the catheter for regional myocardial perfusion measurements during MR‐guided catheterizations. This study investigates the labeling efficiency of catheter‐mounted coils under varying conditions to enable robust iASL measurements. Methods The

Visualisation of latent fingerprint on wild bird eggshells by alternate light sources following superglue fuming [PDF]

open access: yes, 2015
The theft of the eggs of endangered or protected species of bird, and subsequent reduction in wildlife population, is a significant problem worldwide. Detection rates are comparatively low towards this type of crime and fingerprinting of egg shells is ...

Multi‐Walled Carbon Nanotube Reinforced Polyacrylamide‐Acrylic Acid Nanocomposite Hydrogels With Superior Mechanical and Tribological Performance as Focal Cartilage Substitute

open access: yesPolymer Engineering &Science, EarlyView.
ABSTRACT Though mimicking cartilage's structure, hydrogels often present weak mechanical performance, which limits their use in cartilage repair. Here, nanocomposite hydrogel was synthesized by incorporating multi‐walled carbon nanotubes (CNTs) into a covalently bonded polyacrylamide/polyacrylic acid (PAAm/PAAc) hydrogel. Fourier transform infrared and
