Self-clotting method improves cell block preparation

Self-motion improves head direction cell tuning.

Head direction (HD) cells respond when an animal faces a particular direction in the environment and form the basis for the animal's perceived directional heading. When an animal moves through its environment, accurate updating of the HD signal is required to reflect the current heading, but the cells still maintain a representation of HD even when the animal is motionless. This finding suggest...

Sacrificial-post templating method for block copolymer self-assembly.

A sacrificial-post templating method is presented for directing block copolymer self-assembly to form nanostructures consisting of monolayers and bilayers of microdomains. In this approach, the topographical post template is removed after self-assembly and therefore is not incorporated into the final microdomain pattern. Arrays of nanoscale holes of different shapes and symmetries, including me...

Preparation and self-assembly behavior of polystyrene-block-poly (dimethylaminoethyl methacrylate) amphiphilic block copolymer using atom transfer radical polymerization

Asymmetric and semi-symmetric amphiphilic diblock copolymers polystyrene-block-poly (dimethylaminoethyl methacrylate) (PS-b-PDMAEMA) with the same PS block length of 62 repeat units and quite short (3 repeat units) or equivalent (47 repeat units) length of PDMAEMA have been prepared simply by varying the ratio of the bromine-terminated macroinitiator polystyrene (PS-Br) to DMAEMA using atom tra...

A self-checking cell logic block for fault tolerant FPGAs

This paper proposes a self-checking Cell Logic Block (CLB) that can be used as building block for on-line testable FPGAs. The proposed cell consists, basically, of a 4 input Look-UpTable @UT) and a D FlipFlop. The CLB is designed using pass-transistor-based multiplerers, either to select the output of the Cinput Lm, or to select signals from other CLBs. The proposed CLB architecture is characte...
