In this paper we propose a structured doubling algorithm (SDA) for the computation of the minimal nonnegative solutions to the nonsymmetric algebraic Riccati equation (NARE) and its dual equation simultaneously, for a singular case. Similar to the Newton’s method we establish a global and linear convergence for SDA under the singular condition, using only elementary matrix theory. Numerical exp...

We say that a mechanism is harmless if no student can ever misreport his preferences so that he does not hurt but someone else. We consider a large class of rules which includes the Boston, the agent-proposing deferred acceptance, and the school-proposing deferred acceptance mechanisms (sDA). In this large class, the sDA happens to the unique harmless mechanism. We next provide two axiomatic ch...

Solar photovoltaic power generation has become the focus of world energy market. However, weak continuity and variability solar data severely increase grid operating pressure. Therefore, it is necessary to propose a new refined targeted forecasting method broaden channels. In this paper, hybrid model (KM-SDA-ABWO-RBF) based on radial basis function neural networks (RBFNNs), adaptive black widow...

In this paper, a new lifting-based shape-direction-adapti discrete wavelet transform (SDA-DWT) which can be used for arbitraril shaped segments is proposed. The SDA-DWT contains three major techniques: the lifting-based DWT, the adaptive directional technique, and the concept of object-based compression in MPEG-4. With SDA-DWT, the number of transformed coefficients is equal to the number of pi...

The link between mental representation (MREP) structures and motor performance has been evidenced for a great variety of movement skills, but not for the human gait. Therefore the present study sought to investigate the cognitive memory structures underlying the human gait in young and older adults. In a first experiment, gait parameters at comfortable gait speed (OptoGait) were compared with g...

The consumption of EPA and DHA has been associated with reduced risk for cardiovascular disease morbidity and mortality. Mean intakes of EPA and DHA in the United States and elsewhere are below levels recommended by health authorities. The main non-marine source of dietary (n-3) fatty acids (α-linolenic acid) is poorly converted to EPA in humans. Stearidonic acid (SDA) is a non-marine fatty aci...

OBJECTIVES The aim of this survey was to determine how a sample of dentists working in general dental practice in the UK sought to restore the mouths of patients who had shortened dental arches (SDAs). STUDY DESIGN A survey was conducted over a period of six months on four commercial dental laboratories. Cases of SDAs comprising the anterior teeth and 2 to 4 premolars were examined; dental pr...

Histidine kinases are used extensively in prokaryotes to monitor and respond to changes in cellular and environmental conditions. In Bacillus subtilis, sporulation-specific gene expression is controlled by a histidine kinase phosphorelay that culminates in phosphorylation of the Spo0A transcription factor. Sda provides a developmental checkpoint by inhibiting this phosphorelay in response to DN...

The Shortened Dental Arch (SDA) concept introduced as early as 1981 by Kayser and was accepted by a great majority of dentists but not widely practiced. The SDA comprising anterior and premolar teeth in general fulfill the requirements of a functional dentition. Patients’ needs and demands vary much and should be individually assessed but the SDA concept deserves to be included in all treatment...

Abstract A trivial case in input–output structural decomposition analysis is a of product variables, or factors, where one factor an inverse—typically, Leontief inverse—of sum other factors. There may be dozens and hundreds such factors that describe the changes subsets technical coefficients. The existing literature offers ambiguous guidance this case. solution consistent with index number the...
