In this paper we present sufficient conditions for the existence of a bounded real rational unit in H∞ to exactly interpolate to points in the right half plane (RHP). It is shown that these sufficient conditions are equivalent to the necessary and sufficient conditions for the existence of a bounded real irrational unit in H∞ to interpolate to points in the RHP, as initially described by Tannen...

Rose hip powder (RHP) alleviates osteoarthritis (OA) due to its anti-inflammatory and cartilage-protective properties. Substances contained in RHP might contribute to its clinical efficacy. The activity of two RHP (i.e., RH-A, from the whole fruit, RH-B, from fruits without seeds) was investigated in human peripheral blood leukocytes (PBL) and primary chondrocytes (NHAC-kn). RH-A and RH-B dimin...

AIMS The present study aimed to compare the surgical outcomes of patients receiving laparoscopic reversal of Hartmann's procedure (RHP) with those receiving open surgery. METHODS Records of all patients with RHP performed in our unit (including laparoscopic and open surgery) between 2000 and 2012 were retrieved. Data were retrospectively reviewed and compared. RESULTS Eighty-two RHPs were p...

Contest theory predicts the evolution of a stable mixture of different strategies for fighting. Here, we investigate the possibility that stable between-individual differences in startle-response durations influence fighting ability or 'resource-holding potential' (RHP) in the beadlet sea anemone, Actinia equina. Both winners and losers showed significant repeatability of pre-fight startle-resp...

Asymmetries in competitive ability can determine the outcome of social interactions in animals and are often expressed through differences in sexual traits. Competitive ability (resource holding potential, RHP), trait expression and ultimately reproductive success may vary with an individual's age or experience. In some species, reproductively mature males delay acquisition of some adult traits...

Positive-strand RNA viruses replicate their genomes on membranes with virus-induced rearrangements such as single- or double-membrane vesicles, but the mechanisms of such rearrangements, including the role of host proteins, are poorly understood. Brome mosaic virus (BMV) RNA synthesis occurs in ≈70 nm, negatively curved endoplasmic reticulum (ER) membrane invaginations induced by multifunctiona...

The presence of right half plane (RHP) zeros in the transfer function relating the base torque to the tip position has long been the source of diiculty in noncollocated control of a Single Flexible Link (SFL). In this paper, we suggest an alternative noncollocated measurement called the virtual angle of rotation. We then show the following. a) The tranfer function with this output does not have...

A non-communicating rudimentary horn is an uncommon site for ectopic pregnancy. Rudimentary horn pregnancy (RHP) is a rare entity but associated with grave clinical consequences. Majority of these cases if not detected timely end up in uterine rupture and present as an obstetrical emergency. We present this case of a 32-year-old, third gravida with a 12 weeks live gestation in the right rudimen...

Abstract We investigate a Riemann–Hilbert problem (RHP), whose solution corresponds to group of q -orthogonal polynomials studied earlier by Ismail et al . Using RHP theory we determine new asymptotic results in the limit as degree approach infinity. The formulation also enables us obtain further properties. In particular, consider how class and their behaviours change under translations -discr...

The theory of (Muckenhoupt) weights arises in many areas of analysis, for example in connection with bounds for singular integrals and maximal functions on weighted spaces. We prove that a certain averaging process gives a method for constructing Ap weights from a measurably varying family of dyadic Ap weights. This averaging process is suggested by the relationship between the Ap weight class ...
