    Bennett Based Balanced Butterfly Linkage, Deployable Linkage with Inherent Balance

    No full text
    In this paper it is shown how a 2-DoF inherently force balanced spatial deployable Butterfly Linkage is found consisting of four entangled similar Bennett linkages moving synchronously and with the common center of mass in the central joint. This linkage is derived from the Grand 4R Four-Bar Based Inherently Balanced Linkage Architecture by selecting a planar linkage with four entangled similar 4R four-bar linkages to which the Bennett conditions are applied. The inherent balance conditions are calculated, which are independent of the Bennett angles, and a CAD-model of the linkage is presented.Accepted Author ManuscriptMechatronic Systems Desig

    Like It Is Episode #225 -- Interview with Lerone Bennett, Jr.

    No full text
    This episode of Like It Is features an interview with historian and author Lerone Bennett, who discusses the resilience of Black culture and the ongoing struggle against racism and systemic oppression. Bennett highlights how Black Americans have historically faced setbacks, such as during Reconstruction and post-Civil Rights gains, emphasizing the importance of unity and collective action. He stresses that despite cultural deprivation, Black people have retained core traits that sustain their survival. Bennett also advocates for recognizing the significance of history and roots to understand identity and progress, and calls for continuous efforts to build community, cohesion, and activism to combat racism and inequality

    Nanospring behaviour of ankyrin repeats

    No full text
    Ankyrin repeats are an amino-acid motif believed to function in protein recognition; they are present in tandem copies in diverse proteins in nearly all phyla(1). Ankyrin repeats contain antiparallel alpha-helices that can stack to form a superhelical spiral(2). Visual inspection of the extrapolated structure of 24 ankyrin-R repeats(2) indicates the possibility of spring-like behaviour of the putative superhelix. Moreover, stacks of 17-29 ankyrin repeats in the cytoplasmic domains of transient receptor potential (TRP) channels have been identified as candidates for a spring that gates mechanoreceptors in hair cells as well as in Drosophila bristles(3-5). Here we report that tandem ankyrin repeats exhibit tertiary-structure-based elasticity and behave as a linear and fully reversible spring in single-molecule measurements by atomic force microscopy. We also observe an unexpected ability of unfolded repeats to generate force during refolding, and report the first direct measurement of the refolding force of a protein domain. Thus, we show that one of the most common amino-acid motifs has spring properties that could be important in mechanotransduction and in the design of nanodevices.
