In the past few years, several articles have been devoted to the study of molecular computing based on DNA in order to implement algorithms for solving some NP-complete problems and simulate logic gates in silicon-based computers. A great deal of effort has been made on using DNA to implement simple logic gates, such as simple 1-bit comparators and simple adders, or to solve NP-complete problem...

We discuss a new method for realizing number-resolving and non-demolition photo detectors by strong coupling of light to individual single photon emitters, which act as strong optical nonlinearities. As a specific application we show how these elements can be integrated into an error-proof Bell state analyzer, whose efficiency exceeds the best possible performance with linear optics even for a ...

We consider time slot interchangers (TSIs) which are built from 2×2 exchange switches and delays and which are useful for time division multiplexed (TDM) systems in telecommunications and pipelined systems such as time multiplexed optical multiprocessors. We formulate a general method for constructing TSIs based on multistage interconnection networks in the space domain via space-to-time mappin...

The separation of circulating tumor cells from the bloodstream with high purity plays a crucial role in treatment cancer. Design and fabrication cell sorters based on numerical models can lead to optimized terms throughput, purity, size. Based model, symmetric sharp corner microchannel was developed this study achieve more compact sorter high-purity output. Sharp corners generate centrifugal in...

One of the most frequent operations performed on database is searching. To perform this operation we have different kinds of searching algorithms, some of which are Binary Search, Linear Search, Quadratic search[1], but these and all other searching algorithms work only on data, which are previously sorted. An efficient algorithm is required in order to make the searching algorithm fast and eff...

Measuring the state of a quantum system is a fundamental process in quantum mechanics and plays an essential role in quantum information and quantum technologies. One method to measure a quantum observable is to sort the system in different spatial modes according to the measured value, followed by single-particle detectors on each mode. Examples of quantum sorters are polarizing beam-splitters...

Cell sorting of viable biological specimens has become widespread in laboratories involved in basic and clinical research. As these samples can contain infectious agents, precautions to protect instrument operators and the environment from hazards arising from the use of sorters are paramount. This unit presents a revised and updated version of the biosafety guidelines for sorting of unfixed ce...

The comparator is a very basic and useful arithmetic component of digital systems. An individual, compact, high-performance, good cost-benefit ratio comparator core plays an important role on almost all hardware sorters. The study proposes a tine cost-performance ratio comparator design. Based on modified 1’s complement principle and conditional sum adder scheme, the proposed design has small t...
