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.

We propose the formation of LEED patterns using a highly convergent beam forming a probe of nanometer dimensions. A reflection rocking curve may then be recorded in many diffraction orders simultaneously. Multiple scattering calculations show that the intensity variations within these rocking curves is as sensitive to the parameters describing the surface dipole layer as conventional I/V scans....
