We present the dynamic formulations for sliding beams that are deployed or retrieved through prismatic joints. The beams can undergo large deformation, large overall motion, with shear deformation accounted for. Until recently, the sliding beam problem has been tackled mostly under small deformation assumptions, or under quasi-static motion. Here we employ geometrically-exact beam theory. Two t...

Expression patterns of the shell matrix protein genes MSI31 and MSI60 in the pearl sac epithelium were examined by in situ hybridization 38 days after implantation, and related to pearl quality. A pearl sac that produced a nacreous pearl showed very weak expression of MSI31 and strong expression of MSI60. A pearl sac, which yielded a prismatic pearl, strongly expressed MSI31 and very weakly exp...

We report major advances in the analysis of synchrotron 3D datasets acquired from human healthy and carious dental enamel. Synchrotron tomographic data for three samples a non-carious reference tooth sample were collected with voxel size 325 nm total volume 815.4 × 685.4 μm3. The results compared conventional X-ray tomography, optical microscopy, focused ion beam-scanning electron microscopy. C...

Abstract We define, for each quasisyntomic ring R (in the sense of Bhatt et al., Publ. Math. IHES 129 (2019), 199–310), a category $\mathrm {DM}^{\mathrm {adm}}(R)$ admissible prismatic Dieudonné crystals over and functor from p -divisible groups to . prove that this is an antiequivalence. Our main cohomological tool formalism recently developed by Scholze.

Molecular dynamic simulations were performed for ice I(h) with a free surface by using four water models, SPC/E, TIP4P, TIP4P/Ice, and TIP4P/2005. The behavior of the basal plane, the primary prismatic plane, and of the secondary prismatic plane when exposed to vacuum was analyzed. We observe the formation of a thin liquid layer at the ice surface at temperatures below the melting point for all...

The testing of mode III and mixed mode failure is every so often encountered in the dedicated literature of mechanical characterization of brittle and quasi-brittle materials. In this work, the application of the mixed strain displacement ε − u finite element formulation to three examples involving skew notched beams is presented. The use of this FE technology is effective in problems involving...

Control of soft-bodied systems is challenging, as the absence of rigidity typically implies distributed deformations and infinite degrees-of-freedom. In this paper, we demonstrate closedloop control of three elastomer beams that vary in bending stiffness. The most stiff beam is comprised of a single prismatic structure made from a single elastomer. In the next beam, increased flexibility is int...

In situ resource utilization (ISRU) and automation are necessary. The logical first step of intention is to focus on our neighbor, the Moon, first. This work aims expand knowledge lunar aggregate simulant (LAS) based ilmenite rock, which available in Central Europe. Prismatic mortar samples were prepared standard sand LAS. measurements conducted using several different destructive (DT) strength...
