Beyond goniometry: 3D digital twinning of droplets from a single image

Droplet, EarlyView.
We present a method to produce physics‐informed three‐dimensional digital twins of droplets from a single image for wettability analyses. We validate the method with goniometry and demonstrate its capabilities with advancing‐receding contact angle measurements, irregularly shaped droplets, and multi‐droplet systems, indicating strong potential for in ...

Comparing different stimulus configurations for population receptive field mapping in human fMRI

Frontiers in Human Neuroscience, 2015
Population receptive field (pRF) mapping is a widely used approach to measuring aggregate human visual receptive field properties by recording non-invasive signals using functional MRI.

Ultra Wide Swath Imaging With Multi-Channel SAR Systems [PDF]

, 2008
Multi-channel radar systems allow for overcoming the inherent limitation of conventional synthetic aperture radar (SAR). An example is the combination of digital beamforming on receive in elevation with multi-aperture SAR signal reconstruction in azimuth

Agility of vortex-based nanocontact spin torque oscillators

, 2009
We study the agility of current-tunable oscillators based on a magnetic vortex orbiting around a point contact in spin-valves. Theory predicts frequency-tuning by currents occurs at constant orbital radius, so an exceptional agility is anticipated.

Additives Promote Divergent Reactivity in Photolytic Deoxygenation and Lactonization Reactions of Cobalt Alkoxycarbonyls

European Journal of Organic Chemistry, EarlyView.
We report a carbonylation‐homolysis process to access acyl radicals that can undergo decarboxylation or cyclization onto tethered alkenes. In both cases, ligands and additives are shown to influence the outcome to give saturated or unsaturated products, in some cases with isomerization of the initial products.

Time-domain stability of parametric synchronization in a spin-torque nano-oscillator based on a magnetic tunnel junction

, 2017
We report on a time-domain study of parametric synchronization in a magnetic tunnel junction based spin torque nano-oscillator (STNO). Time-domain measurements of the instantaneous frequency ($f_{i}$) of a parametrically synchronized STNO show random ...

Path finding strategies in scale-free networks

, 2002
We numerically investigate the scale-free network model of Barab{\'a}si and Albert [A. L. Barab{\'a}si and R. Albert, Science {\bf 286}, 509 (1999)] through the use of various path finding strategies.

Antibacterial Activity of Fresh and Autoclaved Platelet‐Rich Fibrin on Pseudomonas aeruginosa: An In Vitro Study

Journal of Clinical Laboratory Analysis, EarlyView.
This in vitro study compared the antibacterial effects of fresh and autoclaved platelet‐rich fibrin (PRF) on Pseudomonas aeruginosa (P. aeruginosa). Using standardized methodologies, that is, disk diffusion, colony‐forming unit assays, and scanning electron microscopy, this study reported that both fresh and autoclaved PRF exhibit antibacterial effects

Implications of "peak oil" for atmospheric CO2 and climate

, 2007
Unconstrained CO2 emission from fossil fuel burning has been the dominant cause of observed anthropogenic global warming. The amounts of "proven" and potential fossil fuel reserves are uncertain and debated.
