Manifold embedding for curve registration

We focus on the problem of finding a good representative of a sample of random curves warped from a common pattern f. We first prove that such a problem can be moved onto a manifold framework. Then, we propose an estimation of the common pattern f based on an approximated geodesic distance on a suitable manifold. We then compare the proposed method to more classical methods

Type 1 diabetes

Type 1 diabetes is a chronic autoimmune disease characterised by insulin deficiency and resultant hyperglycaemia. Knowledge of type 1 diabetes has rapidly increased over the past 25 years, resulting in a broad understanding about many aspects of the disease, including its genetics, epidemiology, immune and β-cell phenotypes, and disease burden. Interventions to preserve β cells have been tested, and several methods to improve clinical disease management have been assessed. However, wide gaps still exist in our understanding of type 1 diabetes and our ability to standardise clinical care and decrease disease-associated complications and burden. This Seminar gives an overview of the current understanding of the disease and potential future directions for research and care

Partial containment control over signed graphs

In this paper, we deal with the containment control problem in presence of antagonistic interactions. In particular, we focus on the cases in which it is not possible to contain the entire network due to a constrained number of control signals. In this scenario, we study the problem of selecting the nodes where control signals have to be injected to maximize the number of contained nodes. Leveraging graph condensations, we find a suboptimal and computationally efficient solution to this problem, which can be implemented by solving an integer linear problem. The effectiveness of the selection strategy is illustrated through representative simulations.Comment: 6 pages, 3 figures, accepted for presentation at the 2019 European Control Conference (ECC19), Naples, Ital

The Enigmatic Culture of Business Alliances

The market and economic significances of business alliances are high, but so too are their failure rates. In an attempt to expand on the organizational knowledge regarding such failures (or successes) this paper identifies potential variables that may influence the ultimate success of such ventures. Absorptive and relational capabilities of organizations may be good indicators of alliance compatibility, depending on the size and nature of the industry. The central goal of this paper is to lay out variables and potential tools of measurement for AIQ and RIQ (AIQ = Absorptive Organizational Intelligence Quotient; RIQ = Relational Organizational Intelligence Quotient). Absorptive IQ and Relational IQ can be broken down into measurable components and a better understanding of what constitutes best partners may be formulated

A Phylogenetic Analysis of the Genus Fragaria (Strawberry) Using Intron-Containing Sequence from the ADH-1 Gene

The genus Fragaria encompasses species at ploidy levels ranging from diploid to decaploid. The cultivated strawberry, Fragaria×ananassa, and its two immediate progenitors, F. chiloensis and F. virginiana, are octoploids. To elucidate the ancestries of these octoploid species, we performed a phylogenetic analysis using intron-containing sequences of the nuclear ADH-1 gene from 39 germplasm accessions representing nineteen Fragaria species and one outgroup species, Dasiphora fruticosa. All trees from Maximum Parsimony and Maximum Likelihood analyses showed two major clades, Clade A and Clade B. Each of the sampled octoploids contributed alleles to both major clades. All octoploid-derived alleles in Clade A clustered with alleles of diploid F. vesca, with the exception of one octoploid allele that clustered with the alleles of diploid F. mandshurica. All octoploid-derived alleles in clade B clustered with the alleles of only one diploid species, F. iinumae. When gaps encoded as binary characters were included in the Maximum Parsimony analysis, tree resolution was improved with the addition of six nodes, and the bootstrap support was generally higher, rising above the 50% threshold for an additional nine branches. These results, coupled with the congruence of the sequence data and the coded gap data, validate and encourage the employment of sequence sets containing gaps for phylogenetic analysis. Our phylogenetic conclusions, based upon sequence data from the ADH-1 gene located on F. vesca linkage group II, complement and generally agree with those obtained from analyses of protein-encoding genes GBSSI-2 and DHAR located on F. vesca linkage groups V and VII, respectively, but differ from a previous study that utilized rDNA sequences and did not detect the ancestral role of F. iinumae

Training Army Judge Advocates to Advise Commanders as Operational Law Attorneys

Today, U.S. Army commanders and the military lawyers assigned to advise them—Army Judge Advocates—find themselves operating in areas of extreme legal complexity, where nuanced political and strategic implications are often at the forefront, and where “black letter law” is rarely sufficient to render competent advice. Through formal training at The Judge Advocate General’s Legal Center and School, observance of the lessons learned by other Judge Advocates collected by the Center for Law and Military Operations, and hands-on training at Combat Training Centers, Army Judge Advocates are prepared to address the ever-increasing operational demands of the commanders who rely on their advice

Varieties of service economies in Europe

This paper identifies the varieties and dynamics of service economies in Europe, analysing the role of knowledge base and innovative efforts and their evolution across time and countries. Results based on aggregated macroeconomic data indicate that there is no convergence trend towards a single service economy model. Moreover, different service economies models can be associated with institutional and welfare state diversity. When analysing a comprehensive set of indicators at a disaggregated level a more detailed pattern of service economies emerges. The structural composition of countries plays a prominent role, while heterogeneity is driven by uneven knowledge bases and innovative efforts

Established and emerging biomarkers for the prediction of type 1 diabetes: a systematic review

Type 1 diabetes (T1D) is an autoimmune disease with a prolonged and variable latent period that culminates in the destruction of pancreatic β-cells and the development of hyperglycemia. There is a need for diagnostic biomarkers to detect more accurately detect individuals with prediabetes to expedite targeting for prevention and intervention strategies. To assess the current ability to predict the insidious development of T1D, we conducted a comprehensive systematic review for established and prospective predictive markers of T1D using the Medline, OVID, and EMBASE databases. Resulting citations were screened for relevance to subject. Our research generated five major categories of markers that are either currently used or forthcoming: genetic, autoantibodies, risk score quantification, cellular immunity, and β-cell function. The current standard used to assess T1D onset or predisposition focuses on autoimmune pathology and disease-associated autoantibodies. Research studies in general go beyond autoantibody screening and assess genetic predisposition, and quantitate risk of developing disease based on additional factors. However, there are few currently used techniques that assess the root of T1D: β-cell destruction. Thus, novel techniques are discussed with the potential to gauge degrees of β-cell stress and failure via protein, RNA, and DNA analyses

Comprehensive User Engagement Sites (CUES) in Philadelphia: A Constructive Proposal

This paper is a study about Philadelphia’s comprehensive user engagement sites (CUESs) as the authors address and examine issues related to the upcoming implementation of a CUES while seeking solutions for its disputed questions and plans. Beginning with the federal drug schedules, the authors visit some of the medical and public health issues vis-à-vis safe injection facilities (SIFs). Insite, a successful Canadian SIF, has been thoroughly researched as it represents a paradigm for which a Philadelphia CUES can expand upon. Also, the existing criticisms against SIFs are revisited while critically unpackaged and responded to in favor of the establishment. In the main section, the authors propose the layout and services of the upcoming CUES, much of which would be in congruent to Vancouver’s Insite. On the other hand, the CUES would be distinct from Insite, as the authors emphasize, in that it will offer an information center run by individuals in recovery and place additional emphasis on early education for young healthcare professionals by providing them a platform to work at the site. The paper will also briefly investigate the implementation of a CUES site under an ethical scope of the Harm Reduction Theory. Lastly, the authors recommend some strategic plans that the Philadelphia City government may consider employing at this crucial stage

The Relationship of Worry About Hypoglycemia With Diabetes-specific and Typical Youth Behavior Among Emerging Adults With Type 1 Diabetes

PURPOSE: Little is known about the relationship of worry about hypoglycemia with diabetes-specific and typical youth behaviors among emerging adults with type 1 diabetes. This study's purpose was to examine the relationship among worry about hypoglycemia, diabetes management, and glycemic control within the context of alcohol use, hypoglycemia-related weight control behaviors, depressive symptoms, and impulse control among emerging adults with type 1 diabetes. RESEARCH DESIGN AND METHODS: The sample was 181 emerging adults with type 1 diabetes who were part of a larger study. Path analysis was used to test associations among worry about hypoglycemia, diabetes management, hypoglycemia-related weight control behaviors (WCB), alcohol use, impulse control, depressive symptoms, and glycemic control. RESULTS: Path model fit and modification indices suggested that a feedback loop between worry about hypoglycemia and diabetes management should be incorporated into the original model. Youth with fewer depressive symptoms reported fewer hypoglycemia-related WCB and less worry about hypoglycemia; those with higher impulse control had less alcohol use and better diabetes management; those with lower alcohol use had more worry about hypoglycemia; and better glycemic control was associated with better diabetes management. CONCLUSIONS: Health care professionals need to understand how multiple factors related to worry about hypoglycemia and diabetes management interact in emerging adults. In the context of depressive symptoms, impulse control, alcohol use, and hypoglycemia-related WCB, the path model results suggest several potential avenues for intervening to improve glycemic control in emerging adults
