We proposed and analyzed implementation of the single-qutrit quantum gates based on stimulated Raman adiabatic passage (STIRAP) between magnetic sublevels in atoms coupled by pulsed laser fields. This technique requires only the control of the relative phase of the driving fields but do not involve any dynamical or geometrical phases, which make it independent of the other interaction details: ...

Today, the use of CMOS technology for the manufacture of electronic ICs has faced many limitations. Many alternatives to CMOS technology are offered and made every day. Quantum-dot cellular automata (QCA) is one of the most widely used. QCA gates and circuits have many advantages including small size, low power consumption and high speed. On the other hand, using special digital gates called re...

Natural genetic circuits enable cells to make sophisticated digital decisions. Building equally complex synthetic circuits in eukaryotes remains difficult, however, because commonly used components leak transcriptionally, do not arbitrarily interconnect or do not have digital responses. Here, we designed dCas9-Mxi1-based NOR gates in Saccharomyces cerevisiae that allow arbitrary connectivity an...

rockfill dams are accounted as useful measures in watershed management projects. how-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures however; there is no general relationship to estimate the sediment transport rat...

background: it is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. in the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. materials and methods: in this study 60 units of packed red cells were examined before and after pa...

The current study investigated factors related to specific phobia domains and differences in patterns among African American and Caucasian American adults. Subjects were 100 African Americans and 121 Caucasian Americans who completed the Fear Survey Schedule--Second Edition (FSS-II). Fears related to specific phobia domains were first examined, with frequencies differing between African America...

We prove an embedding theorem that says a convex body can pass through a triangular hole∆ if and only if the convex body can be congruently embedded in a right triangular prism with base ∆. Combining this with a known result on congruent embeddings of a regular tetrahedron in a triangular prism, we show that a regular tetrahedron with unit edge can pass through an equilateral triangular hole in...

We construct the exchange gate with small elementary gates on the space of qudits, which consist of three controlled shift gates and three ”reverse” gates. This is a natural extension of the qubit case. We also consider a similar subject on the Fock space, but in this case we meet with some different situation. However we can construct the exchange gate by making use of generalized coherent ope...

A framework for concurrent, object-oriented natural language parsing is introduced. The underlying grammar model is fully lexicalized, headdriven, dependency-oriented, and structured along multiple inheritance hierarchies. The computation model relies upon the actor paradigm, with concurrency entering through asynchronous message passing. Protocols for establishing basic dependency relations an...

We argue for a performance-based design of natural language grammars and their associated parsers in order to meet the constraints imposed by real-world NLP. Our approach incorporates declarative and procedural knowledge about language and language use within an object-oriented specification framework. We discuss several messagepassing protocols for parsing and provide reasons for sacrificing c...
