Although it is known vocal fold adduction is achieved through laryngeal muscle activation, it is still unclear how interaction between individual laryngeal muscle activations affects vocal fold adduction and vocal fold stiffness, both of which are important factors determining vocal fold vibration and the resulting voice quality. In this study, a three-dimensional (3D) finite element model was ...

We investigate the competition between granular mixing and segregation in a sphere rotating and rocking on two orthogonal axes. Operation corresponds to the continuous-flow regime and the flow within the sphere is three-dimensional and time-periodic. Experimental results are organized in a frequency/amplitude phase diagram showing modes of segregation (band formation/no axial bands); segregated...

Mechanically driven mobile artificial mothers effectively prevented the development of stereotyped body-rocking in rhesus monkeys. Monkeys were maternally separated at birth and assigned to 2 groups. Both groups were placed with surrogates, identical in construction except that for 1 group the surrogate was in motion 50% of the time from 0500 hours to 2400 hours each day, and for the other grou...

We report on the deaths of two infants aged 10 1/2 and 11 weeks who were found face down in the angle between the base and side of their frame-suspended rocking cradles. Locking pins designed to prevent tilting of the cradles were not in place in either case. Investigation of the two cradles associated with the infant deaths and six other similar rocking cradles available for purchase in South ...

The new Lcica RM 2165 automatic, heavy-duty microtome has an advanced step motor that permits an exact specimen feed and reproducible sectioning results. Features include 70 mm vertical stroke length, unique step trim function, and programmable specimen retraction. Technical features include a handwheel rocking sectioning mode; the motorized specimen feed can be linked to change the handwheel t...

Individuals with autism spectrum disorders (ASDs) have significant visuomotor processing deficits, atypical motoric behavior, and often substantial problems connecting socially. We suggest that the perceptual, attentional, and adaptive timing deficiencies associated with autism might directly impact the ability to become a socially connected unit with others. Using a rocking chair paradigm prev...

Complacency and a coronavirus variant help to explain why the country, once pandemic success story, couldn’t withstand surge now rocking South America.

The presence of left ventricular (LV) dyssynchrony in heart failure patients has been largely associated with improved outcome and LV reverse remodelling after cardiac resynchronization therapy (CRT). However, definition of LV dyssynchrony remains controversial. While current guidelines include QRS duration (.120 ms) and morphology [left bundle branch block (LBBB) vs. non-LBBB] as marker of LV ...
