We describe protocols for the fabrication of microfluidic devices in plastics using a number of different embossing masters. Masters were fabricated by deep reactive ion etching (DRIE) of silicon (100), wet etching of silicon (100) and (110), and SU-8 processing. Structures embossed into a cyclo-olefin polymer were characterized in terms of the quality of pattern transfer as well as of the surf...

Aiming at the problem of virtual reality and data processing algorithm online video packaging, one transmission scheme uses TILES in HEVC to block then applies MP4Box pack generate a DASH stream. A method is proposed process same panoramic with different quality. By designing new index measure complexity coding tree unit, this predicts depth unit by using spatial correlation video, skipping unn...

Abstract We introduce Dehn invariants as a useful tool in the study of the inflation of quasiperiodic space tilings. The tilings by “golden tetrahedra” are considered. We discuss how the Dehn invariants can be applied to the study of inflation properties of the six golden tetrahedra. We also use geometry of the faces of the golden tetrahedra to analyze their inflation properties. We give the in...

In this paper we formalize the concept of square tiles with colored corners, a new kind of tiles closely related to Wang tiles. We construct aperiodic sets of square tiles with colored corners and several new aperiodic sets of Wang tiles using isomorphisms between tilings. The smallest aperiodic set of square tiles with colored corners we have created consists of 44 tiles over 6 colors.

Proactive tile-based video streaming can avoid motion-to-photon latency of wireless virtual reality (VR) by computing and delivering the predicted tiles to be requested before playback. All existing works either focus on designing predictors or allocating communications resources. Yet latency, successively executed prediction, communication, tasks should accomplished within a predetermined time...

We present an active tile assembly model which extends Winfree’s abstract tile assembly model [31] to tiles that are capable of transmitting and receiving binding site activation signals. In addition, we introduce a mathematical framework to address self-similarity and recursion within the model. The model is applied to show a recursive assembly of an archetypal self-similar aperiodic tiling kn...

In this paper we explore the relation between Wang Tiles and Schonfinkel Combinators in order to investigate Functional Combinators as an programming language for Self-assembly and DNA computing. We show: How any combinatorial program can be expressed in terms of Wang Tiles, and again, how any computation of the program fits into a grid of tiles of a suitable finite, tile set, and finally, how ...

In periodontal practice, root coverage after marginal soft tissue recession requires daily clinical decisions. Numerous longitudinal human studies have been presented to support the efficacy and predictability of different mucogingival surgical techniques for root coverage. Over the years, root coverage procedure using the subepithelial connective tissue graft with variations has emerged as the...

We discuss the potential merits of using the diffraction of light to detect dimensional variations of microand nano-fluidic components embossed in transparent thermoplastic polymers. We describe one particular scheme for measuring the depths of an array of approximately micron-depth, parallel embossed channels. The component to be measured is placed in contact with a row of nine phase-relief ho...
