Development of an active fly-by-wire flight control system

A summary of the YF-16 flight control system is presented. The basic functions of the flight control system are discussed, as well as the unique features such as Relaxed Static Longitudinal Stability (RSS), Fly By Wire (FBW), and Side Stick Pilot's Controller (SSC). In addition, the basic philosophy behind the selection of the flight control system functions and unique features is discussed

Physics of the Pseudogap State: Spin-Charge Locking

The properties of the pseudogap phase above Tc of the high-Tc cuprate superconductors are described by showing that the Anderson-Nambu SU(2) spinors of an RVB spin gap 'lock' to those of the electron charge system because of the resulting improvement of kinetic energy. This enormously extends the range of the vortex liquid state in these materials. As a result it is not clear that the spinons are ever truly deconfined. A heuristic description of the electrodynamics of this pseudogap-vortex liquid state is proposed.Comment: Submitted to Phys Rev Letter

Cognitive appraisals, emotional reactions, and their associations with three forms of peer-victimization

Victimized students’ cognitive appraisals (perceived threat, control) are related to emotional reactions. Furthermore, psychosocial wellbeing is differentially associated with form of victimization (direct vs. indirect), suggesting that emotional reactions to direct and indirect victimization may also differ. The present study therefore evaluated appraisals and emotional reactions within the context of verbal, physical, and indirect victimization experiences, testing a mediational model which considers appraisals to mediate the effect of victimization upon emotional reaction. Participants were 146 students (44% male) aged 10-13 years attending mainstream schools in Scotland (UK). Self-report measures assessed peer-victimization (physical, verbal, indirect), appraisal (control, threat) and emotional reaction (anger, sadness). All forms of victimization were positively associated with both emotions. Threat appraisals were positively associated with all forms of victimization and control appraisals were negatively associated with physical victimization. The relationships between appraisals and emotions varied according to victimization type. The effects of victimization upon emotions were not mediated via appraisals. These results extend our understanding of the relationships between victimization and affect
