    The archaeoacoustics of San Vitale, Ravenna

    No full text
    This research tests and assesses whether sixth-century social and cultural dynamics can be archaeologically identified by including the study of acoustics in the context of extant Late Antique Christian architecture, namely the centrally planned domed octagonal church of San Vitale at Ravenna. Implementing a holistic archaeological research strategy that includes human sensory perception of acoustical phenomena is the best approach to unravelling the complexities of social and cultural mechanisms operating in the sixth-century Mediterranean basin. The methods and issues of Archaeoacoustics are critiqued and developed in order to comment on the intentionality of acoustic attributes in sixth-century ecclesiastical architecture.The space syntax of San Vitale has been considered for isovists at key locations during the liturgical procession and sequence of the Mass celebration. These are compared with mapped areas of perceiving the acoustic characteristics of Clarity and Reverberation Time. Combining the visual and acoustic analysis of San Vitale, with a better understanding of its date and construction phases, the physical geometry and temporal logic of the church are discussed in relation to the reflexive exchange of influence between Ravenna, Milan and Constantinople. It is posited that liturgical and musical time and tempo is materially expressed in the evident and conceptual substance of San Vitale, a suggestion that offers a springboard for future study and debate

    Retracted. ERK and the F-box protein betaTRCP target STAT1 for degradation

    No full text
    This article has been withdrawn by Paul A. Townsend, Richard A. Knight, Sean P. Barry, David S. Latchman, and Anastasis Stephanou. An investigation at University College London determined that a duplicated blot in Fig. 1, A and B, the GAPDH blot is the same, flipped horizontally. The withdrawing authors sincerely apologize to the scientific community for any confusion or adverse consequences resulting from the publication of the article. Original Abstract:The transcription factor STAT1 has roles in development, homeostasis, cellular differentiation, and apoptosis and has been postulated to function as a tumor suppressor. STAT1 is activated by tyrosine or serine phosphorylation in response to specific cytokines or following a variety of stress-induced stimuli. STAT1 activity is carefully regulated to prevent sustained STAT1-mediated transcription, although the molecular mechanisms involved in the modulation of STAT1 stability are poorly understood. Here we show that activated STAT1 is degraded at the proteasome by a mechanism involving the F-box E3 ligase, SCF(betaTRCP). Active p42/p44 MAPK-ERK phosphorylates STAT1 on serine 727 and targets it for proteasomal degradation. SCF(betaTRCP) binds wild-type STAT1 but not the nonphosphorylatable mutant STAT1(S727A). Moreover, silencing betaTRCP expression or pharmacological inhibition of ERK activity stabilized STAT1 expression. These data suggest that constitutively active ERK may inappropriately degrade STAT1, with loss of its pro-apoptotic and tumor suppressor functions

    Newton's Laws

    No full text
    Authored and curated by David P. Stern, this series of web pages, part of "From Stargazers to Starships," describes Newton's three laws of motion and the two concepts on which they are based, force and inertia. The author breaks down the page in this fashion: the concept of force, motion against outside resistance, and motion with significant resistance. The author also provides additional links for further study on the life of Issac Newton. A lesson plan for instructors is also provided
