Stochastic control system parameter identifiability

The parameter identification problem of general discrete time, nonlinear, multiple input/multiple output dynamic systems with Gaussian white distributed measurement errors is considered. The knowledge of the system parameterization was assumed to be known. Concepts of local parameter identifiability and local constrained maximum likelihood parameter identifiability were established. A set of sufficient conditions for the existence of a region of parameter identifiability was derived. A computation procedure employing interval arithmetic was provided for finding the regions of parameter identifiability. If the vector of the true parameters is locally constrained maximum likelihood (CML) identifiable, then with probability one, the vector of true parameters is a unique maximal point of the maximum likelihood function in the region of parameter identifiability and the constrained maximum likelihood estimation sequence will converge to the vector of true parameters

Attraktivität ist nicht alles: Eine regressionsanalytische Untersuchung produkt- und testimonialbasierter Determinanten konsumrelevanten Verhaltens

Die Werbewirkungsforschung belegt, dass sowohl die Attraktivität der Person, die ein Produkt bewirbt (Testimonial) (vgl. Halliwell & Dittmar, 2004), als auch das Ausmaß an Identifikation des Konsumenten mit diesem Testimonial (vgl. Basil, 1996), relevante Determinanten der Werbewirksamkeit sind. Bislang nicht systematisch untersucht ist hingegen, in welchem Ausmaß beide Variablen im Bereich der Laien-Testimonials (d.h. typische Produktnutzer) bei gleichzeitiger Berücksichtigung jeweils bedeutsam sind. Unter Verwendung eines experimentellen between-subjects Designs (N =480), bei dem auf Printanzeigen neben der Produktkategorie auch die Attraktivität und das Geschlecht des Testimonials manipuliert wurden, belegt eine multiple Regressionsanalyse, dass nur Identifikation, nicht aber Attraktivität zusätzlich zu zentralen kaufrelevanten Einstellungskomponenten (z. B. Bewertung der Produktqualität) einen signifikanten inkrementellen Vorhersagewert hinsichtlich kaufrelevanten Verhaltens aufweist. Dies deutet somit darauf hin, dass einem attraktiven Laien-Testimonial gegebenenfalls eines vorzuziehen ist, welches möglicherweise sogar etwas weniger attraktiv ist, jedoch dem Betrachter Identifikationsmöglichkeiten bietet

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Indiana Medical Resident’s Knowledge of Surrogate Decision Making Laws

Introduction During the care of incapacitated patients, physicians, and medical residents discuss treatment options and gain consent to treat through healthcare surrogates. The purpose of this study is to ascertain medical residents’ knowledge of healthcare consent laws, application during clinical practice, and appraise the education residents received regarding surrogate decision making laws. Methods Beginning in February of 2018, 35 of 113 medical residents working with patients within Indiana completed a survey. The survey explored medical residents’ knowledge of health care surrogate consent laws utilized in Indiana hospitals and Veterans Affairs (VA) hospitals via clinical vignettes. Results Only 22.9% of medical residents knew the default state law in Indiana did not have a hierarchy for settling disputes among surrogates. Medical residents correctly identified which family members could participate in medical decisions 86% of the time. Under the Veterans Affairs surrogate law, medical residents correctly identified appropriate family members or friends 50% of the time and incorrectly acknowledged the chief decision makers during a dispute 30% of the time. All medical residents report only having little or some knowledge of surrogate decision making laws with only 43% having remembered receiving surrogate decision making training during their residency. Conclusions These findings demonstrate that medical residents lack understanding of surrogate decision making laws. In order to ensure medical decisions are made by the appropriate surrogates and patient autonomy is upheld, an educational intervention is required to train medical residents about surrogate decision making laws and how they are used in clinical practice

Regulation of mammalian gastrin/CCK receptor (CCK2R) expression in vitro and in vivo

The gastrin/CCK receptor (CCK2R) mediates the physiological functions of gastrin in the stomach, including stimulation of acid secretion and cellular proliferation and migration, but little is known about the factors that regulate its expression. We identified endogenous CCK2R expression in several cell lines and used luciferase promoter–reporter constructs to define the minimal promoter required for transcription in human gastric adenocarcinoma, AGS, and rat gastric mucosa, RGM1, cells. Consensus binding sites for SP1, C/EBP and GATA were essential for activity. Following serum withdrawal from RGM1 and AR42J cells, endogenous CCK2R mRNA abundance and the activity of a CCK2R promoter–reporter construct were significantly elevated. Transcription of CCK2R was also increased in AGS-GR and RGM1 cells by gastrin through mechanisms partly dependent upon protein kinase C (PKC) and mitogen/extracellular signal-regulated kinase (MEK). Gastrin significantly increased endogenous CCK2R expression in RGM1 cells, and CCK2R protein expression was elevated in the stomach of hypergastrinaemic animals. In mice with cryoulcers in the acid-secreting mucosa, CCK2R expression increased progressively in the regenerating mucosa adjacent to the ulcer repair margin, evident at 6 days postinjury and maximal at 13 days. De novo expression of CCK2R was observed in the submucosa beneath the repairing ulcer crater 6–9 days postinjury. Many of the cells in mucosa and submucosa that expressed CCK2R in response to cryoinjury were identified as myofibroblasts, since they coexpressed vimentin and smooth muscle α-actin but not desmin. The data suggest that increased CCK2R expression might influence the outcome of epithelial inflammation or injury and that the response may be mediated in part by myofibroblasts
