This paper establishes new results regarding control problems for parametrized families of pairs ( 'systems') {(A(x), B(x)),xeX}, where A(x) is an n x n and B(x) is an n x m real matrix for each x (with n,m fixed integers), and the parameter x belongs to a manifold X. To be found is a new parametrized family {K(x),x~X} such that a given design criterion is satisfied by the closed-loop matrix A(...

OBJECTIVES To determine patient preferences and cost differences between home-based and hospital-based chemotherapy. DESIGN Randomised crossover trial. SETTING A tertiary cancer hospital in Melbourne, Victoria. PARTICIPANTS 20 patients who required chemotherapy suitable for administration at home. INTERVENTIONS Patients were assigned at random to receive their first chemotherapy treatme...

The accuracy of the SPACETRACK General Perturbations program over short periods is evaluated for a number of cases. They show that oscillatory terms resulting from drag perturbations contribute heavily to errors at low altitudes, and that these terms must be eliminated if the first order theory is to be used for high accuracy in these circumstances. It appears that the evaluation technique empl...

In a previous paper, Bhaduri and Whelan (2008), we presented a simple model of hedge fund liquidity. That paper explored the fact that not being able to pull one’s money out of an investment instantaneously at a fair price can have a powerful impact on the portfolio. Real world examples include the 1993 Metallgesellschaft debacle (Smithson, 1998) and the recent difficulties experienced by the B...

We present an approach to invariant matching. In this approach, an object or a pattern is invariantly represented by an object-centered description called an attributed relational structure (ARS) embedding invariant properties and relations between the primitives of the pattern such as line segments and points. Noise eeect is taken into account such that a scene can consist of noisy sub-parts o...

INCE the original observation of STURTEVANT (1919) a large body of data has accumulated substantiating the contention that, in Drosophila melanogaster females, inversion heterozygosity in one part of the genome increases the frequency of recombination in the remainder of the genome. This effect has been demonstrated for spontaneous meiotic crossing over (see, for instance, SCHULTZ and REDFIELD ...

urveillance of over-the-counter (OTC) pharmaceutical sales may someday be used to give public health offi cials an early warning about developing public health conditions. To acquire confi dence in this surveillance, it is necessary to establish fi rmly that OTC sales may be used to predict changes in clinical conditions with a useful time lead. This article reports the magnitude of correlation...

2014 Absorption measurements performed by means of photoacoustic absorption (PAA)-technique in wedge-shaped TiO2’ Ta2O5, and ZrO2 single-layer films at 03BB = 488 nm, 515 nm, and 647 nm permit a separate determination of bulk and interface absorption, respectively. For TiO2 and Ta2O5 films investigated the filmsubstrate interface absorption Afs dominates over the air-film interface absorption A...

During the recent debt crisis in Europe, policy makers responded to the controversy surrounding CDS by implementing a series of policies that banned CDS trading. Sambalaibat (2014) documents that a temporary CDS ban increased bond market liquidity but a permanent ban instead decreased bond market liquidity. To explain these patterns, I build a search-theoretic model of OTC bond and CDS markets ...
