The stability properties of a fairly general diserete-time adaptive control scheme are analyzed. Sufficient conditions forL^{\infty}stability in the presence of disturbances are given. The stability results are used to prove convergence of the process outputs in the disturbance-free case, without requiring any a priori stability assumption.

Popular Abstract in Swedish Den horisontella segregeringen på grund av kön är idag den största på arbetsmarknaden; betydligt större än bland annat segregering på grund av etnicitet. Trots att vi kommit långt med arbetet för jämställdhet, tenderar män och kvinnor fortfarande att välja olika typer av utbildningar och yrken. Dessa tendenser finns redan i gymnasieskolan, där det råder könsdominans inoGender remains a key predictor of vocational choice. The present thesis aimed to investigate three social psychological barriers to nontraditional career choice. Study Ӏ showed that threats to gender identity may lead to more gender-typical occupational preferences among adolescents. The results suggested a unique effect of gender identity threat, as a control threat did not have the same effect.

BACKGROUND: Many studies have indicated that colon and rectal cancers differ in etiology and histology. OBJECTIVE: The aim of this study was to investigate whether the associations of colon and rectal cancers with any other (discordant) cancer were site specific. DESIGN: A novel approach was implemented in which cancer risks were analyzed in families with increasing numbers of family members diagn

We present the microscopic model for collective effects, built on string–string interactions (string shoving and rope hadronization), recently implemented in the PYTHIA8 and DIPSY event generators. Rope hadronization is shown to give a good description of strangeness enhancement across pp, pA and AA collision systems, while string shoving qualitatively describes the ridge observed in pp collisions

Scholars continue to debate whether economic development affects regime type. This article argues that a clear relationship exists between development and the electoral component of democracy, but not – or at least less so – between development and other components of broader understandings of democracy. This is so because development enhances the power resources of citizens and elections provide

To identify genetic variants associated with diabetic retinopathy (DR), we performed a large multiethnic genome-wide association study. Discovery included eight European cohorts (n = 3,246) and seven African American cohorts (n = 2,611). We meta-analyzed across cohorts using inverse-variance weighting, with and without liability threshold modeling of glycemic control and duration of diabetes. Vari

Dorsoventrality in leaves has been shown to depend on the pre-patterned expression of KANADI and HD-ZIPIII genes within the plant shoot apical meristem (SAM). However, it has also been proposed that asymmetric auxin levels within initiating leaves help establish leaf polarity, based in part on observations of the DII auxin sensor. By analyzing and quantifying the expression of the R2D2 auxin senso

Background Norwood surgery provides a palliative surgical option for hypoplastic left heart syndrome and has been available in Sweden since 1993. The practice of prenatal ultrasound screening was gradually implemented in the same era, resulting in an increased prenatal detection rate. Our primary aims were to study changes in the incidence of live births, prenatal detection rate, and the terminati

Charles Bonnet syndrome (CBS) is characterised by recurrent, complex and vivid visual hallucinations in the absence of cognitive dysfunction. Individuals with CBS usually maintain insight into the unreal nature of their hallucinatory experiences. There is a strong association between CBS and acquired visual loss and the most commonly described ocular pathology is age-related macular degeneration.

BACKGROUND: During recent years, stepwise approaches to health checks have been advanced as an alternative to general health checks. In 2013, we set up the Early Detection and Prevention project (Tidlig Opsporing og Forebyggelse, TOF) to develop a stepwise approach aimed at patients at high or moderate risk of a chronic disease. A novel feature was the use of a personal digital mailbox for recruit

Glycoproteins represent a group of important biomarkers for cancer and other life-threatening diseases. Selective detection of specific glycoproteins is an important step for early diagnosis. Traditional glycoprotein assays are mostly based on lectins, antibodies, and enzymes, biochemical reagents that are costly and require special cold chain storage and distribution. To address the shortcomings
