The behavior of droplets trapped in geometric structures is essential to droplet manipulation applications such as for droplet transport. Here we show that directional droplet movement can be realized by a V-shaped groove with the movement direction controlled by adjusting the surface wettability of the groove inner wall and the cross sectional angle of the groove. Experiments and analyses show...

With groove we mean the subjective experience of wanting to move rhythmically when listening to music. Previous research has indicated that physical properties of the sound signal contribute to groove as opposed to mere association due to previous exposure, for example. Here, a number of quantitative descriptors of rhythmic and temporal properties were derived from the audio signal by means of ...

To elucidate the possible role of structural waters in stabilizing bent DNA, various conformations of AT-containing decamers, (A5T5)2 and A10:T10, were studied by Monte Carlo simulations. The duplexes were constrained to reproduce the NMR inter-proton distances for the A-tracts at two temperatures: ~5° and ~35°C. Analysis of the water shell structures revealed a strong correlation between the g...

PURPOSE Groove pancreatitis is a rare specific form of chronic pancreatitis that extends into the anatomical area between the pancreatic head, the duodenum, and the common bile duct, which are referred to as the groove areas. We present the diagnostic modalities, pathological features and clinical outcomes of a series of symptomatic patients with groove pancreatitis who underwent pancreaticoduo...

BACKGROUND There is a lack of evidence on the relationship between prematurity and palatal abnormalities. The aim of this study was to evaluate the incidence of palatal groove, the associated factors and the persistence time in preterm infants from birth to 24 months of age. METHODS The children's data, medical history and eating habits were collected using a questionnaire answered by the leg...

The crystal structure of a B-type DNA hexanucleotide duplex complexed with the porphyrin molecule nickel-[tetra-N-methyl-pyridyl] porphyrin has been solved by multiwavelength anomalous diffraction phasing and refined to an R factor of 11.5% at a resolution of 0.9 A. The structure has been solved and refined as two crystallographically independent duplexes, stacked end to end. Contrary to expect...

This experiment explored the effects of controlled manipulations of three parameters of tactile gratings, groove width (1.07-2.53 mm), contact force (30-90 g), and scanning speed (40-120 mm/s), on the responses of cells in second somatosensory cortex (SII) of awake monkeys that were performing a groove-width classification task with passively presented stimuli. A previous experiment involving a...

Slowed gait in patients with Parkinson's disease (PD) can be improved when patients synchronize footsteps to isochronous metronome cues, but limited retention of such improvements suggest that permanent cueing regimes are needed for long-term improvements. If so, music might make permanent cueing regimes more pleasant, improving adherence; however, music cueing requires patients to synchronize ...
