Perhaps it is unacademic to start with the word “perhaps.” Doing so implies uncertainty, a “mortal sin” for academia that demands precision and decisive action.The however, real. Ac...

In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...

Epigenetic strategies control the orderly acquisition and maintenance of neuronal traits. A complex network of transcriptional repressors and co-repressors mediates gene specificity for these strategies. In this issue of Cell, a study by Ballas and coworkers (Ballas et al., 2005) provides insight into the early lineage commitment events during neurogenesis. This study demonstrates that regulati...

Rest has been examined only sporadically in the nursing literature, primarily as a physiological need closely related to sleep. The article describes the concept of rest from a variety of perspectives and lays the foundation for further analysis. Themes of physical, mental, and spiritual components of rest emerge as the concept is explored. Further analysis of the concept of rest in both health...

Rest is a health-related phenomenon. Researchers have explored the phenomenon of rest, but further concept development is recommended. The aim of my study was to develop and describe a concept of rest, from interviews with a total of 63 participants about their lived experiences of rest. I performed the developing process in two stages: first with descriptive phenomenology and second with a her...
