Tile-based self-assembly is a model of “algorithmic crystal growth” in which square “tiles” represent molecules that bind to each other via specific and variable-strength bonds on their four sides, driven by random mixing in solution but constrained by the local binding rules of the tile bonds. In the late 1990s, Erik Winfree introduced a discrete mathematical model of DNA tile assembly called ...

OIl August 4, 1906, I resected tile left tibial diaphysis of a girl aged fourteen years for sarcoma diagnosed clinically and radiologically (Figs. I and 2). Tile segment excised was replaced by a graft of equal length from tile fibula, the soft tissue attacilments of which were disturbed as little as possible durillg mobilisation in order to preserve tile blood supply. My reason for undertaking...

The two-by-two dot centering model enables predicting the spectral reflectance of color halftones and does not depend on a specific halftoning algorithm. It requires measuring the reflectances of a large number of two-by-two calibration tile patterns. Spectral measurement of hundreds or thousands of tile patterns is cumbersome and time consuming. In order to limit the number of measurements, we...

We introduce a domain-specific language (DSL) for creating sets of tile types for simulations of the abstract Tile Assembly Model. The language defines objects known as tile templates, which represent related groups of tiles, and a small number of basic operations on tile templates that help to eliminate the error-prone drudgery of enumerating such tile types manually or with low-level construc...

We use the abstract tile assembly model of Winfree [6], which models the aggregation of monomers called tiles that attach one at a time to a growing structure, starting from a single seed tile, in which bonds (“glues”) on the tile are specific (glues only stick to glues of the same type on other tiles) and cooperative (so that multiple weak glues are necessary to attach a tile). The general ide...

A content-based tile retrieval system based on the underlying multispectral Markov random field representation is introduced. Single tiles are represented by our approved textural features derived from especially efficient Markovian statistics and supplemented with Local Binary Patterns (LBP) features representing occasional tile inhomogeneities. Markovian features are on top of that also invar...

This paper investigates the impact of proper tile size selection on the power the power consumption for tile-based processors. We refer to this investigation as a tile granularity study. This is accomplished by distilling the architectural cost of tiles with different computational widths into a system metric we call the Granularity Indicator (GI). The GI is then compared against the bisection ...

We describe R&D results on optical properties of a scintillating tile//ber system for the SDC barrel electromagnetic calorimeter. The tile//ber system uses a wavelength shifting ber to readout the signal of a scintillating plate (tile) and a clear ber to transmit the signal to a phototube. In the SDC calorimeter design, four of tile//ber systems are grouped as a 22 tile package so that the gap ...
