Gaussian mixture model (GMM)-based predictive coding of line spectral frequencies (LSFs) has gained wide acceptance. In such coders, each mixture of a GMM can be interpreted as defining a linear predictive transform coder. In this paper, we use Kalman filtering principles to model each of these linear predictive transform coders to present GMM Kalman predictive coding. In particular, we show how s

Using magnetic relaxation dispersion (MRD), we have previously shown that the four internal water molecules in bovine pancreatic trypsin inhibitor (BPTI) exchange with bulk water on time scales between 10(-8) and 10(-4) s at room temperature. Because this exchange is controlled by the protein structure, internal water molecules can be used to probe rare conformational fluctuations. Here, we report

The breast cancer-associated gene Di12 encodes a novel protein, which was found overexpressed in invasive ductal carcinomas of the breast. In experiments designed to assess the role of the Di12 gene in oncogenesis, the overexpression of 339 N-terminal amino acids of this gene in NIH3T3 cells resulted in cellular transformation and in vivo tumorigenesis. NIH3T3-Di12 tumor cell growth was partly rev

Chronic venous ulcers are characterized by chronic inflammation. Heme and iron, originating from blood cell hemolysis as well as extravascular necrosis, have been implicated as important pathogenic factors due to their promotion of oxidative stress. It was recently reported that the plasma and tissue protein alpha1-microglobulin is involved in heme metabolism. The protein binds heme, and a carboxy

The effects of sulfate anions on the uptake of Pb(II) onto goethite were investigated at the molecular level using in situ Pb L-III-EXAFS and ATR-FTIR spectroscopies. Macroscopic uptake data show that Pb uptake can be enhanced by at least 30% at pH 5 in the presence of 3.16 mM sulfate and that sulfate uptake at pH 7 can be enhanced by more than a factor of 3 in the presence of 1.0 mM Pb. Consisten

Software inspections are regarded as an important technique to detect faults throughout the software development process. The individual preparation phase of software inspections has enlarged its focus from only comprehension to also include fault searching. Hence, reading techniques to support the reviewers on fault detection are needed. Usage-based reading (UBR) is a reading technique, which foc

To examine a putative role for neuronal nitric oxide synthase (nNOS) in early vertebrate development we investigated nNOS mRNA expression and cGMP production during development of the zebrafish Danio rerio. The nNOS mRNA expression in the central nervous system (CNS) and periphery showed a distinct spatio-temporal pattern in developing zebrafish embryo and young larvae. nNOS mRNA expression was fi

The maximum concentration of water-insoluble solids (WIS) in simultaneous saccharification and fermentation (SSF) is restricted due to inhibition of the enzymes and the yeast, as well as mass transport problems caused by the viscosity of the pretreated material. However, the higher the concentration of WIS during SSF the less energy is needed in the subsequent distillation and evaporation steps. I

Electronic commerce is expected to influence a wide range of supply chain systems and thus lead to unidentified environmental impacts. Current studies discussing the impacts have the problem common in that they arrive either at conflicting or un-generalisable results. This article addresses the issue of methodology and proposes an assessment model for the resolution of this problem. Some important

The loss of beta cells in type 1 diabetes is the consequence of a T cell-dependent autoimmune attack. Autoantibodies against GAD65 (Mr 65.000 isoform of glutamic acid decarboxylase), IA-2 (insulinoma-associated protein IA-2) or insulin, alone or in combination, predict disease. Preclinical studies in spontaneously diabetic rodents suggest that immunomodulation with autoantigens might alter the cou

Objectives: We undertook an international, multicenter study to describe the clinical picture and to estimate the bleeding risk in a group of obligatory carriers of type 3 von Willebrand disease (VWD). Patients and methods: Obligatory carriers (OC) of type 3 VWD were identified by the presence of offspring with type 3 VWD or by being an offspring of a type 3 patient. Normal controls were age- and

A resonator system has been fabricated directly on a pre-processed CMOS chip. The system is to be used for high sensitivity mass sensing applications in air and vacuum. The resonator system, corresponding of a cantilever and structures for electrostatic actuation and capacitive read-out, have been defined by electron beam lithography on top of a charge and radiation sensitive CMOS layer in predefi

Digital feedback suppression (DFS) enables users of hearing instruments (HI) to benefit from amplification levels that normally would provoke whistling or poor sound quality. A standardized test for the measurement of DFS benefit is not available. This paper proposes and evaluates an objective method for assessment of extra feedback-free amplification (headroom) provided by a given DFS. It is show

The unique morphology of the toes of the great crested grebe (Podiceps cristatus), which are asymmetrically lobed with a narrower skin flap on the lateral side of the toe, enables these birds to swim very efficiently. Here we study video recordings of a diving grebe and stroboscopic pictures of its moving feet and conclude that the bird uses a hydrodynamically lift-based foot (power) stroke to pro

The dust detector system onboard Galileo has recoding dust impacts incircumjovian space since the spacecraft was injected into a bound orbitabout Jupiter in December 1995. This is the sixth in a series of papersdedicated to presenting Galileo and Ulysses dust data. We present datafrom the Galileo dust instrument for the period January to December 1996when the spacecraft completed four orbits about

OBJECTIVE: This study assessed the role of cholesterol-rich membrane regions, including caveolae, in the regulation of arterial contractility. Methods and Results- Rat tail artery devoid of endothelium was treated with the cholesterol acceptor methyl-beta-cyclodextrin, and the effects on force and Ca2+ handling were evaluated. In cholesterol-depleted preparations, the force responses to alpha1-adr

This paper shows how discontinuities in the process of drug delivery enable but also underdetermine the isolation of a culprit in adverse medication events. A case example illustrates how we are forced to abandon conceptualizations of blame that assume a dichotomy (either culpable or not), and shift instead to a more nuanced version that estimates the degree to which an actor desired, generated, o
