Direct Visual Servoing (DVS) considers pixel brightness directly as input of robot control. Recent DVS variants consider image processing smoothing or frequency domain transforms, resulting in large convergence domains. This letter proposes to defocus optically smooth images without processing. The Defocus-based shows domains competing with the state-of-the-art, larger some challenging cases, f...

Quantum secure data transfer is an important topic for quantum cyber security. We propose a scheme to realize in the basis of direct communication (QSDC). In this proposal, transmitted encoded pulse shape single optical qubit, which emitted from trapped atom owned by sender and received receiver with another atom. The encoding process can be implemented high fidelity controlling time-dependent ...

Planning based on propositional SAT(isfiability) is a powerful approach to computing step-optimal plans given a parallel execution semantics. In this setting: (i) a solution plan must be minimal in the number of plan steps required, and (ii) non-conflicting actions can be executed instantaneously in parallel at a plan step. Underlying SAT-based approaches is the invocation of a decision procedu...

background: ataxia with oculomotor apraxia type 1 (aoa1) shows early onset with autosomal recessive inheritance and is caused by a mutation in the aprataxin (aptx) gene encoding for the aptx protein. methods: in this study, a 7-year-old girl born of a first-cousin consanguineous marriage was described with early-onset progressive ataxia and aoa, with increased cholesterol concentration and decr...
