In this work, the problem of designing feedback controllers for the rejection of narrow-band disturbances is considered. The design technique proposed herein is based upon the overparameterization of a nominal minimum-variance controller, which is designed by means of an ARMA model of a sinusoid in noise. The extra degrees of freedom so introduced are used to improve the robustness of the nominal
In her work on virtue ethics Rosalind Hursthouse has formulated an Aristotelian criterion of rightness that understands rightness in terms of what the virtuous person would do. It is argued here that this kind of criterion does not allow enough room for the category of the supererogatory and that right and wrong should rather be understood in terms of the characteristic behavior of decent persons.
Objective-Treatment strategies for squamous cell carcinoma of the head and neck (SCCHN) are based on the TNM classification. Biological markers that can predict the response to therapy have so far not been introduced. The objective of this study was to investigate cyclin D1 deregulation relative to sensitivity to cisplatin. Material and Methods-This was a laboratory study of 23 established Univers
Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy i
AIMS/HYPOTHESIS: The metabolic syndrome is a cluster of factors contributing to increased risk of cardiovascular disease and type 2 diabetes but unifying mechanisms have not been identified. Our aim was to study whether common variations in 17 genes previously associated with type 2 diabetes or components of the metabolic syndrome and variants in nine genes with inconsistent association with at le
Gaia is an ESA space astrometry mission due for launch in 2011-12. We describe part of the work carried out in the Gaia Data Processing and Analysis Consortium, namely the Astrometric Global Iterative Solution (AGIS) currently being implemented at the European Space Astronomy Center (ESAC) in Spain and largely based on algorithms developed at Lund Observatory. Some provisional results based on sim
The implicit assumption of many scientific and regulatory frameworks that ecosystems impacted by human pressures may be reverted to their original condition by suppressing the pressure was tested using coastal eutrophication. The response to nutrient abatement of four thoroughly studied coastal ecosystems that received increased nutrient inputs between the 1970s and the 1980s showed that the traje
It was recently proposed to use variational functionals based on manybody perturbation theory for the calculation of the total energies of many-electron systems. The accuracy of such functionals depends on the degree of sophistication of the underlying perturbation expansions. The energy functionals are variational in the sense that they can be evaluated at rather crude approximations to their ind
The authors review the work of G.D. Forney, Jr., on the algebraic structure of convolutional encoders upon which some new results regarding minimal convolutional encoders rest. An example is given of a basic convolutional encoding matrix whose number of abstract states is minimal over all equivalent encoding matrices. However, this encoding matrix can be realized with a minimal number of memory el
Scand J Caring Sci; 2009 Utilization of medical healthcare among people receiving long-term care at home or in special accommodation Aim: To investigate the utilization of medical healthcare, hospital care and outpatient care, during a 1-year period in relation to informal care, multimorbidity, functional status and health complaints and to long-term care at home or in special accommodation among
PURPOSE: To evaluate the long-term results of a prospective, longitudinal case series of untreated, traumatic triangular fibrocartilage complex (TFCC) tears found in displaced distal radial fractures. METHODS: Between 1995 and 1997, 51 patients (24 men, 27 women; age, 20-57 y) with a displaced distal radius fracture had wrist arthroscopy to identify associated injuries. Forty-three patients had c
The international legal framework regulating the problem of human trafficking contains the presumption that the return of victims of human trafficking to their countries of origin is the standard resolution for their cases. However, victims might have legitimate reasons for not wanting to go back. For those victims, resort to the legal framework of the European Convention on Human Rights could be
Moraxella catarrhalisis a human respiratory pathogen that causes acute otitis media in children and is associated with exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD). The first step inM. catarrhaliscolonization is adherence to the mucosa, epithelial cells, and extracellular matrix (ECM). The objective of this study was to evaluate the role ofM. catarrhalisint
The gene for Vitreoscilla hemoglobin (VHb) has been introduced and expressed in Nicotiana tabaccum (tobacco). Transgenic tobacco plants expressing VHb exhibited enhanced growth, on average 80-100% more dry weight after 35 days of growth compared to wild-type controls. Furthermore, germination time is reduced from 6-8 days for wild-type tobacco to 3-4 days and the growth phase from germination to f
AIMS: To evaluate the long-term clinical and economic outcomes associated with insulin detemir and neutral protamine hagedorn (NPH) insulin in combination with mealtime insulin aspart in patients with type 1 diabetes in Sweden, based on data from a two-year, multi-national, open-label, randomized, controlled trial.METHODS: Insulin detemir was associated with significant improvements in glycaemic c
