The regulation of the expression of the rus operon, proposed to encode an electron transfer chain from the outer to the inner membrane in the obligate acidophilic chemolithoautroph Acidithiobacillus ferrooxidans, has been studied at the RNA and protein levels. As observed by Northern hybridization, real-time PCR and reverse transcription analyses, this operon was more highly expressed in ferrou...

We present a non-deterministic circuit decomposition technique for approximating an arbitrary single-qubit unitary to within distance that requires significantly fewer non-Clifford gates than deterministic decomposition techniques. We develop “Repeat-Until-Success” (RUS) circuits and characterize unitaries that can be exactly represented as an RUS circuit. Our RUS circuits operate by conditioni...

Posttraumatic radioulnar synostosis (RUS) is a rare event following forearm fractures. Consequences are disabling for patients who suffer from functional limitation in forearm pronosupination. Distal RUS are even more rare and more difficult to treat because of high recurrence rates. The patient we describe in this paper came to our attention with a double distal RUS recurrence and a Darrach pr...

PURPOSE New algorithms are proposed to improve the validity, accuracy and practicality of automatic bone age assessment (ABAA). MATERIALS AND METHODS The concept of object-based region of interest (ROI) was proposed. Thirteen RUS (including radius, ulna and short finger bones) ROIs and seven carpal ROIs were appointed respectively according to Tanner-Whitehouse (TW3) method. Five features inc...

Recently, it was shown that Repeat-Until-Success (RUS) circuits can achieve a 2.5 times reduction in expected depth over ancilla-free techniques for single-qubit unitary decomposition. However, the previously best-known algorithm to synthesize RUS circuits requires exponential classical runtime. In this work we present an algorithm to synthesize an RUS circuit to approximate any given singlequb...

The Reduction-under-Substitution Lemma (RuS), due to van Daalen [Daa80], provides an answer to the following question concerning the lambda calculus: given a reductionM [x := L] N , what can we say about the contribution of the substitution to the result N . It is related to a not very well-known lemma that was conjectured by Barendregt in the early 70’s, addressing the similar question as to t...

The set of programs written in a small subset of pure Prolog called US is shown to accept exactly the class of regular languages. The language US contains only unary predicates and unary function symbols. Also, a subset of US called RUS is shown to be equivalent to US in its ability in accepting the class of regular languages. Every clause in RUS contains at most one function symbol in the head...

In the crystal structure of the title compound, C(39)H(54)BCl(2)P, the phospho-rus atom is coordinated by a dichloro-phenyl-borane unit. The substituted biphenyl group and the two cyclo-hexyl groups at the phospho-rus atom are arranged in such a way to avoid steric crowding in the mol-ecule as far as possible.
