Clusters of eigenvalues for the magnetic Laplacian with Robin condition

We study the Schrödinger operator with a constant magnetic field in the exterior of a compact domain in Euclidean space. Functions in the domain of the operator are subject to a boundary condition of the third type (a magnetic Robin condition). In addition to the Landau levels, we obtain that the spectrum of this operator consists of clusters of eigenvalues around the Landau levels and that they d

An : In vitro evaluation of fibrinogen and gelatin containing cryogels as dermal regeneration scaffolds

Macroporous cryogels containing mixtures of two key components of the dermal extracellular matrix, fibrinogen and collagen-derived gelatin, were evaluated for use as dermal tissue regeneration scaffolds. The infiltration of human dermal fibroblasts into these matrices was quantitatively assessed in vitro using a combination of cell culture and confocal laser scanning microscopy. The extent of cell

Local Labour, Cosmopolitan Toil : Geo-Cultural Dynamics in Swedish Working-Class Fiction

In the renowned and epoch-making working-class novels from the Swedish 1930s, claims for social and economic justice reflect a local struggle with distinctly national and cosmopolitan significance. Generally, these novels can be described as having local characters and settings, national narrative perspectives, and cosmopolitan plots, but a closer look reveals a much more varied picture. There is,

Mid-infrared pumped laser-induced thermal grating spectroscopy for detection of acetylene in the visible spectral range

We present mid-infrared laser-induced thermal grating spectroscopy (IR-LITGS) using excitation radiation around 3 μm generated by a simple broadband optical parametric oscillator (OPO). Acetylene as a typical small hydrocarbon molecule is used as an example target species. A mid-infrared broadband OPO pumped by the fundamental output of a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser was

Emlen funnel experiments revisited : methods update for studying compass orientation in songbirds

Migratory songbirds carry an inherited capacity to migrate several thousand kilometers each year crossing continental landmasses and barriers between distant breeding sites and wintering areas. How individual songbirds manage with extreme precision to find their way is still largely unknown. The functional characteristics of biological compasses used by songbird migrants has mainly been investigat

Exome Genotyping Identifies Pleiotropic Variants Associated with Red Blood Cell Traits

Red blood cell (RBC) traits are important heritable clinical biomarkers and modifiers of disease severity. To identify coding genetic variants associated with these traits, we conducted meta-analyses of seven RBC phenotypes in 130,273 multi-ethnic individuals from studies genotyped on an exome array. After conditional analyses and replication in 27,480 independent individuals, we identified 16 new

Care and services at home for persons with dementia. Structure, process, and outcomes.

The overall aim of this thesis was to investigate formal care and services at home, regarding structure, process, and outcomes, for persons with dementia (aged 65+ years) at risk of nursing home admission. Availability and utilization of formal care and services at home for persons with dementia, from diagnosis to end-of-life stage, in eight European countries was described in study I. A mapping f

The Gaia mission : Science, organization and present status

The ESA space astrometry mission Gaia will measure the positions, parallaxes and proper motions of the 1 billion brightest stars on the sky. Expected accuracies are in the 725 as range down to 15 mag and sub-mas accuracies at the faint limit (20 mag). The astrometric data are complemented by low-resolution spectrophotometric data in the 3301000 nm wavelength range and, for the brighter stars, radi

Baseline trabecular bone and its relation to incident radiographic knee osteoarthritis and increase in joint space narrowing score : directional fractal signature analysis in the MOST study

Purpose To explore the association of baseline trabecular bone structure with incident tibiofemoral (TF) osteoarthritis (OA) and with increase in joint space narrowing (JSN) score. Methods The Multicenter Osteoarthritis Study (MOST) includes subjects with or at risk for knee OA. Knee radiographs were scored for Kellgren–Lawrence (KL) grade and JSN at baseline, 30, 60 and 84 months. Knees (KL ≤ 1)

A 15-Gb/s wireless on-off keying link

Bit-error rate measurements for ON-OFF keying modulation at multigigabit per second rates over a V-band wireless link are presented. Serial data-rates from 2.5 to 20 Gb/s were studied for a 231-1 bit random sequence. Error-free data transfer over a 0.3-m link was achieved at up to 10 Gb/s. Acceptable bit-error rates,

Accurate prediction tools in prostate cancer require consistent assessment of included variables

Objective: The aim of this study was to create a preoperative prediction model predicting extraprostatic tumour growth in men with clinically organ-confined disease from a prospectively collected Swedish cohort. Materials and methods: The study used data from 3386 men in the prospective multi-centre Laparoscopic Prostatectomy Robot Open (LAPPRO) trial, with 14 participating urological departments.

Activity and migratory flights of individual free-flying songbirds throughout the annual cycle : Method and first case study

We describe a method and device (< 1.2 g) for recording, processing and storing data about activity and location of individuals of free-living songbirds throughout the annual cycle. Activity level was determined every five minutes from five 100 ms samples of accelerometer data with 5 s between the sampling events. Activity levels were stored on an hourly basis throughout the annual cycle, allowing

High-Precision Low-Power Wireless Nodes' Synchronization via Decentralized Control

Time synchronization is crucial for wireless sensor networks (WSNs), where operations often rely on time ordering of events. WSNs are deployed in different scenarios, and therefore their timing requirements are often related to the peculiar characteristics of the specific environment they have to act in. Synchronization is anyway always an issue: transactional applications need monotonicity of the
