Design of three-bit binary to gray converter based on metal-insulator-metal plasmonic waveguides.

Using the finite element method and COMSOL version 5.5, a three-bit binary to gray converter with three plasmonic substructures and five input and three output ports was designed. Using a 520 ×200 metal-insulator-metal plasmonic structure, the plasmonic converter was developed.

Experiences of family caregivers of people with spinal cord injury at the neurosurgical units of the Komfo Anokye Teaching Hospital, Ghana.

Background: Spinal cord injury (SCI) often leaves affected persons with a lifelong demand for care. As a result, the effect of the condition goes beyond the injured person to affect family members and significant others who have to adjust their lives to provide care and support. However, little is known about the experiences of these family caregivers regarding the care of people with SCI in Ghana.
