zipper braced frames are an innovative bracing system for steel structures. conventional inverted-v-braced frames exhibit a design problem arising from the unbalanced vertical force generated by the lower story braces when one of them buckles. this adverse effect can be mitigated by adding zipper columns or vertical members connecting the intersection points of the braces above the first floor....

Zipper codes are a framework for describing spatially-coupled product-like codes. Many well-known codes, such as staircase and braided block subsumed into this framework. New types of tiled diagonal delayed zipper introduced along with their software simulation results. Stall patterns that can arise in iterative decoding analyzed, giving means error floor estimation.

DNA origami structures represent an exciting class of materials for use in a wide range biotechnological applications. This study reports the design, production, and characterization “zipper” structure, which contains nine pH-responsive locks. Each lock consists two parts that are attached to zipper’s opposite arms: hairpin single-stranded able form triplex through Hoogsteen base pairing. The s...

The meeting materials from the 3rd Annual Meeting of the International Society for the Prevention of Tobacco Induced Diseases are available as a zip drive in additional file 1 which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

At the merging point, vehicles on the main road must reduce their velocity to avoid slow merging vehicles from a branch road, which leads to a traffic jam. Some researchers point out the effectiveness of a zipper merging pattern for improving the traffic near the merging point. In this study, the authors discuss the effectiveness of a zipper merging pattern using cellular automata simulation. F...

Homeobox genes are present in both plants and animals. Homeobox-leucine zipper genes, however, have been identified thus far only in the small mustard plant Arabidopsis thaliana. This observation suggests that homeobox-leucine zipper genes evolved after the divergence of plants and animals, perhaps to mediate specific regulatory events. To better understand this gene family, we isolated several...

We propose Zipper, a compact representation of incidence and adjacency for manifold triangle meshes with fixed connectivity. Zipper uses on average only 6 bits per triangle, can be constructed in linear space and time, and supports all standard randomaccess and mesh traversal operators in constant time. Similarly to the previously proposed LR (Laced Ring) approach, the Zipper construction reord...

BACKGROUND It is poorly understood how hyperpolarization-activated cyclic nucleotide-gated channels (HCNs) function. RESULTS We have identified a leucine zipper in the S5 segment of HCNs, regulating hyperpolarization-activated and instantaneous current components. CONCLUSION The leucine zipper is essential for HCN channel gating. SIGNIFICANCE The identification and functional characteriza...
