SIMS, GDS.

The Geriatric Depression Scale (GDS).

WHY: Depression is common in late life, effecting nearly five million of the 31 million Americans aged 65 and older. Both major and minor depression are reported in 13% of community dwelling older adults, 24% of older medical outpatients and 43% of both acute care and nursing home dwelling older adults. Contrary to popular belief, depression is not a natural part of aging. Depression is often r...

Sims Speculum Examination

Sims Speculum Examination is an important skill for medical students and doctors. This article presents a comprehensive, concise and evidence-based approach to the use of the Sims Speculum which is consistent with The Principles of Clinical Examination [1]. We describe the signs of pelvic organ prolapse and based on a review of the literature, the precision and accuracy of these signs is discus...

The Schreier-Sims algorithm

A base and strong generating set provides an effective computer representation for a permutation group. This representation helps us to calculate the group order, list the group elements, generate random elements, test for group membership and store group elements efficiently. Knowledge of a base and strong generating set essentially reduces these tasks to the calculation of certain orbits. Giv...

TOF-SIMS in Cosmochemistry

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was introduced into cosmochemistry about a decade ago. Major advantages of TOF-SIMS compared to other ion microprobe techniques are (a) parallel detection of all secondary ions with one polarity in a single measurement – both polarities in subsequent analyses, (b) high lateral resolution, (c) sufficient mass resolution for separation of ...
