Using Quantum Confinement to Uniquely Identify Devices.

Modern technology unintentionally provides resources that enable the trust of everyday interactions to be undermined. Some authentication schemes address this issue using devices that give a unique output in response to a challenge. These signatures are generated by hard-to-predict physical responses derived from structural characteristics, which lend themselves to two different architectures, known as unique objects (UNOs) and physically unclonable functions (PUFs).

A preliminary study into stress in palliative care: optimism, self-efficacy and social support.

Caring for the terminally ill is a demanding, but rewarding area of health care. Stressors unique to this working environment--dealing with patient death rather than cure, and supporting entire family units, for example--put caregivers at risk from stress related illness. This study investigated the buffering effects of optimism, self-efficacy and social support against two measures of stress within the palliative setting.
