Finite codimensional invariant subspaces in Hilbert spaces of analytic functions

Let $\scr H$ denote a Hilbert space consisting of functions analytic on a bounded, open, connected subset $\Omega$ of the complex plane. Given certain natural hypotheses on $\scr H$, the author characterizes the finite-codimensional subspaces of $\scr H$ that are invariant under multiplication by $z$, showing that all such subspaces have the form $(p\scr H)^-$, where $p$ is a polynomial whose zero

Mobile Phones and Politics in China - From Texting to Mobilizing

The penetration of mobile phones in Chinese daily life has made collective actions easier to organize and challenged government censorship. Highlighting this new form of communication, the following essay shows how the traditional mass media’s role as gatekeeper is waning.

Microseminoprotein-Beta Expression in Different Stages of Prostate Cancer.

Microseminoprotein-beta (MSMB, MSMB) is an abundant secretory protein contributed by the prostate, and is implicated as a prostate cancer (PC) biomarker based on observations of its lower expression in cancerous cells compared with benign prostate epithelium. However, as the current literature on MSMB is inconsistent, we assessed the expression of MSMB at the protein and mRNA levels in a comprehen

Assessment of right ventricular volumes and ejection fraction by echocardiography: from geometric approximations to realistic shapes.

Right ventricular volumes and ejection fraction are challenging to assess by echocardiography, but are well established as functional and prognostic parameters. Three-dimensional (3D) echocardiography has become widespread and relatively easy to use, making calculation of these parameters feasible in the large majority of patients. We review past attempts to estimate right ventricular volumes, cur

Pressure at the Bowel Surface during Topical Negative Pressure Therapy of the Open Abdomen: An Experimental Study in a Porcine Model.

BACKGROUND: Topical negative pressure (TNP) therapy is increasingly used in open abdomen management. It is not known to what extent this pressure propagates through the dressing to the bowel surface, potentially increasing the risk of bowel fistula formation. The present study in a porcine model was designed to evaluate pressure propagation. METHODS: A commercially available TNP therapy system (AB

Development of an Automatic Reduction Tool for Chemical Mechanisms and an Optimized Sparse Matrix Solver for Systems of Differential and Algebraic Equations

Abstract An N-Heptane mechanism and a Methane/Propane mechanism have been reduced by an Automatic Reduction Tool (ART) and simulated with two different solver combinations, which solve the set of ordinary differential equations governing the time evolution of the species simultaneously with solving algebraic equations for species that can be considered to be in quasi steady state. The most succes

Subjective emotions, political implications: Thinking through tensions and contradictions in feminist knowledge production

Based on an ongoing research project in which we explore practices, strategies andvisions within feminist activism in a Swedish context, this paper emerges from experiencesduring fieldwork with feminist activist groups. Focusing on tensions and contradictionsencountered during fieldwork, this article problematizes the social and emotional dimen-sions of research. Through a discussion of our intera

Measurement properties of the Arnetz and Hasson stress questionnaire in Swedish university freshmen.

BACKGROUND: The aim of this study was to evaluate the measurement properties of the Arnetz and Hasson seven-item stress questionnaire in order to select high-risk freshmen for a stress and alcohol intervention research project. METHODS: Two complete cohorts of university freshmen at two universities were asked to participate in an intervention study. All subjects responded to seven Visual Analogue

Psychosocial work conditions, unemployment and health locus of control: A population-based study.

AIMS: To investigate the association between psychosocial work conditions, unemployment and lack of belief in the possibility of influencing one's own health. Design/setting/participants/measurements: The 2000 public health survey in Scania is a cross-sectional postal questionnaire study with a 59% participation rate. In total, 5180 persons aged 18-64 years who belonged to the workforce and the un

A spectral analysis is made of a Schrodinger operator with zero-range potential of a one- or two-dimensional lattice in the resonances of an isolated atom and the spectral properties of the crystal is established

Sustainability of exercise-induced increases in bone density and skeletal structure.

BACKGROUND: The prevalence of osteoporosis with related fragility fractures has increased during the last decades. As physical activity influences the skeleton in a beneficial way, exercise may hypothetically be used as a prophylactic tool against osteoporosis. OBJECTIVE: This review evaluates if exercise-induced skeletal benefits achieved during growth remain in a long-term perspective. DESIGN: P
