The problem of designing robust and noise-insensitive PI controllers for pressure-sensor based combustion-timing control was studied through simulation. Different primary reference fuels (PRF) and operating conditions were studied. The simulations were done using a physics-based, control-oriented model with an empirical ignition-delay correlation. It was found that the controllable region, in-betwThe problem of designing robust and noise-insensitive PI controllers for pressure-sensor based combustion-timing control was studied through simulation.

BB rats lose >50% of their islet sympathetic nerve terminals soon after diabetes onset, markedly impairing the glucagon response to activation of these nerves. In this study, we sought evidence that this degree of disease-induced nerve terminal damage affected their neuronal cell bodies. Increased galanin expression was used as a marker of the change of phenotype that occurs in neuronal cell bodie

Human type 1 diabetes mellitus (T1DM) arises through autoimmune destruction of pancreatic β cells and is modeled in many respects by the lymphopenic and spontaneously diabetic BioBreeding (BB) DRlyp-lyp rat Previously, preonset expression profiling of whole DRlyp-lyp pancreatic lymph nodes (PLN) revealed innate immune activity, specifically that of mast cells and eosinophils. Furthermore, we obser

The question of registering two images (or image volumes) acquired with different modalities, and thus exhibiting different contrast, at different positions is addressed based on an extension of global digital image (or volume) correlation. A specific comparison metric is introduced allowing the signature of the different phases to be related. A first solution consists of a Gaussian mixture to des

Hydroquinones are important mediators of electron transfer reactions in soils with a capability to reduce Fe(III) minerals and molecular oxygen, and thereby generating Fenton chemistry reagents. This study focused on 2,6-dimethoxy hydroquinone (2,6-DMHQ), an analogue to a common fungal metabolite, and its reaction with ferrihydrite and goethite under variable pH and oxygen concentrations. Combined

The focus of this article is on public–private partnerships (PPPs). The aim is to both theoretically and empirically illustrate PPP agency problems in four PPP stages, as well as to identify potentially relevant solutions to the agency problems. The study employed a longitudinal case study of one PPP in a municipality in southern Sweden. Through an analysis based on interviews, observations, and d

This paper shows how sustainable and smart strategies can be implemented in cities and how these strategies influence, and are influenced by, performance measurement systems. Drawing upon the Foucauldian notion of governmentality, the authors present the case of Gothenburg in Sweden, where they interviewed the key actors involved in a new sustainability strategy. Translating strategy into performa

OBJECTIVE - Ketosis-prone diabetes (KPD) is an emerging, heterogeneous syndrome. A sound classification scheme for KPD is essential to guide clinical practice and pathophysiologic studies. Four schemes have been used and are based on immunologic criteria, immunologic criteria and insulin requirement, BMI, and immunologic criteria and β-cell function (Aβ classification). The aim of the present stud

Hsu–Kasami–Chien (HKC) are a class of cyclic codes that can correct either burst or random errors. This paper studies the maximum burst-correcting capability of HKC codes. A necessary and sufficient condition for a b- burst-correcting cyclic HKC code is given and simplified as a generalized one for Fire codes. An upper bound on the burstcorrecting capability of HKC codes is derived, which improves

The smaller isoform of glutamate decarboxylase (GAD65) is a major autoantigen in type 1 diabetes (TID). Its hydrophobic character requires detergent to keep the protein in solution, which complicates studies of antigen processing and presentation. In this study an attempt was made to replace detergent with human serum albumin (HSA) for in vitro antigen presentation. Different preparations of recom

OBJECTIVE - Ketosis-prone diabetes (KPD) comprises four subgroups based on the presence or absence of β-cell autoantibodies (A+ or A-) and β-cell functional reserve (β + or β-). Genetic factors could contribute to their distinctive phenotypes. Our aim was to specify the role of HLA class II alleles associated with susceptibility or resistance to autoimmune type 1 diabetes in determining KPD phenot

This dissertation focuses on how to use prototyping as a method for developing models in Management Accounting and Control Systems, a field in Business Administration. It combines three emerging theories: prototyping, Activity Based Costing (ABC) and the Balanced Scorecard (BSc). Prototyping is an alternative to the traditional systems development method. In prototyping end-users play an important

The possible importance of virus infections before the development of islet autoimmunity and then for the appearance of clinical type 1 diabetes is reviewed. There is a lack of specific data on the role of virus to induce islet autoimmunity. There is also a paucity of data to demonstrate that virus infections may contribute to an accelerated disease process resulting in clinical onset of type 1 di

OBJECTIVE - Inflammatory mediators associated with type 1 diabetes are dilute and difficult to measure in the periphery, necessitating development of more sensitive and informative biomarkers for studying diabetogenic mechanisms, assessing preonset risk, and monitoring therapeutic interventions. RESEARCH DESIGN AND METHODS - We previously utilized a novel bioassay in which human type 1 diabetes se

Rodents homozygous for autosomal leptin receptor gene mutations not only become obese, insulin resistant, and hyperleptinemic but also develop a dysregulated immune system. Using marker-assisted breeding to introgress the Koletsky rat leptin receptor mutant (lepr-/lepr-), we developed a novel congenic BBDR.lepr-/lepr- rat line to study the development of obesity and type 2 diabetes (T2D) in the Bi

Distributed algorithms for solving coupled semidefinite programs (SDPs) commonly require many iterations to converge. They also put high computational demand on the computational agents. In this paper we show that in case the coupled problem has an inherent tree structure, it is possible to devise an efficient distributed algorithm for solving such problems. The proposed algorithm relies on predic

Background: The widely expressed protein chorein fosters activation of the phosphoinositide 3 kinase (PI3K) pathway thus supporting cell survival. Loss of function mutations of the chorein encoding gene VPS13A (vacuolar protein sorting-associated protein 13A) causes chorea-acanthocytosis (ChAc), a neurodegenerative disorder paralleled by deformations of erythrocytes. In mice, genetic knockout of c

Background: Type 1 diabetes (T1D) in both humans and BioBreeding (BB) rats is an autoimmune disease that results in complete destruction of islets and insulin dependency for life. Glucagon-like peptide 1 (GLP-1) promotes β cell proliferation and neogenesis and has a potent insulinotropic effect. We hypothesized that the expression of GLP-1 before disease onset would increase islet mass, delay diab
