China's sex ratio imbalance and the surplus of males have received a great deal of attention, but measures of the extent of the marriage squeeze do not take into account the marital status of population. In this paper, we devise an index of the marriage squeeze for the never-married population and use it to project the male marriage squeeze from 2000 to 2060. From the predicted population and n...

Hand velocity and acceleration are coherent with magnetoencephalographic (MEG) signals recorded from the contralateral primary sensorimotor (SM1) cortex. To learn more of this interaction, we compared the coupling of MEG signals with four hand-action-related peripheral signals: acceleration, pressure, force, and electromyogram (EMG). Fifteen subjects performed self-paced repetitive hand-action ...

Abstra t. This paper analyzes the ombined e e t of slip velo ity and transverse roughness on the performan e of a Jenkins model based ferro uid lubriation of a squeeze lm in urved rough annular plates. The slip model of Beavers and Joseph has been invoked to evaluate the e e t of slip velo ity. In order to nd the e e t of surfa e roughness the sto hasti averaging model of Christensen and Tonder...

Natural lung surfactant contains less than 40% disaturated phospholipids, mainly dipalmitoylphosphatidylcholine (DPPC). The mechanism by which lung surfactant achieves very low near-zero surface tensions, well below its equilibrium value, is not fully understood. To date, the low surface tension of lung surfactant is usually explained by a squeeze-out model which predicts that upon film compres...

In these experiments, two plates were grasped between the thumb and forefinger and squeezed together along a linear track. An electromechanical system presented a constant resistance force during the squeeze up to a predetermined location on the track, whereupon the force effectively went to infinity (simulating a wall) or to zero (simulating a cliff). The task of the subject was to discriminat...

OBJECTIVE To investigate anorectal function in women patients with systemic sclerosis (SSc), with and without lower gastrointestinal symptoms. METHODS Anorectal manometry was performed in 16 patients with SSc: six with no or minimal bowel symptoms, seven with constipation, and three with diarrhoea and faecal incontinence. Eleven healthy women acted as control subjects. Pressure data were reco...

The paper summarises the results of laboratory testing of three commercially available magnetorheological (MR) fluids operated in the oscillatory squeeze mode. Tested fluids include the Basonetic 204 and Basonetic 4035 (BASF) and MRF-122EG (Lord Corporation). The oscillatory squeeze mode produces large forces at small displacements. This feature may be well utilised in fabrication of new MR dev...

Triple-differential cross sections for neutrons from high-multiplicity La-La collisions at 250 and 400 MeV per nucleon and Nb-Nb collisions at 400 MeV per nucleon were measured at several polar angles as a function of the azimuthal angle with respect to the reaction plane of the collision. The reaction plane was determined by a transverse-velocity method with the capability of identifying charg...
