In various statistical mechanical models, introduction of a metric into space of prameters gives a new perspective to the phase structure. In this paper, the scalar curvature R of this metric for a one dimensional four-state complex spin model is calculated. It is shown that this parameter has a similar behaviour to the Ising and Potts models.
introduction: it is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. orexin plays an important role in modulation of pain and stress. considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.we evaluated the involvement of ...
In this paper, I want to review theoretical models of two social phenomena: the dynamics of an applauding audience and the collective motion of people in a stadium forming a La Ola wave. In particular, I want to stress how phase transitions occur in these theoretical models and how these transitions emerge macroscopically.
torting the helical structure of the phase) and the nematic phase develops when the equilibrium pitch of the cholesteric phase becomes larger than the sample thick ness. This transition is first order and can easily be observed when approaching a smectic phase, because the cholesteric pitch diverges at this transition. In this way, it is possible to observe the growth of the cholesteric phase ...
introduction: the nucleus paragigantocellularis lateralis (lpgi) is involved in the descending pain modulation. the neurostreoid, 17β-estradiol found in the pgi nucleus and modulates nociception by binding to estrogen receptors and also by allosteric interaction with nmda receptors. in this study, the role of nmda receptors in the 17β-estradiol-induced pain modulation was investigated by assess...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections.Chitosan polyelectrolyte complex...
