This paper examines the use of gradient based methods for extremum seeking control of possibly infinite-dimensional dynamic nonlinear systems with general attractors within a periodic sampled-data framework. First, discrete-time gradient descent method is considered and semi-global practical asymptotic stability with respect to an ultimate bound is shown. Next, under the more complicated setting w
(Schagatay E, Lodin-Sundstrom A. Abrahamsson E. Underwater working times in two groups of traditional apnea divers in Asia: the Ama and the Bajau. Diving and Hyperbaric Medicine. 2011;41(1):27-30.) Introduction: Traditional apnea diving for sea harvesting for a living continues in some communities in Asia, the outcome being dependent on the total underwater working time. We studied dive and surfac
To estimate the production of external ectomycorrhizal mycelia (EMM) in Norway spruce forests with varying nitrogen (N) and phosphorus (P) levels, and to relate this to the N retention capacity of ectomycorrhizal fungi (EMF) and N leaching. Seasonal changes in EMF production (in ingrowth mesh bags) and soil water N (in suction lysimeters) were analyzed after fertilization with N or N combined with
This special issue of Professions & Professionalism seeks to explain the transition of occupations from non-professions to professions and the conditions and causes that generate professions (i.e., the bases of professionalization). Empirically, we use the histories of the Swedish professions, positing that these histories have several close similarities (and, of course, differences) with thos
Granular GaAs(MnAs) layers with different Mn concentration and various layer thickness were grown by MBE method and subjected to annealing at 500A degrees C under ambient and enhanced hydrostatic pressure. Distinct influence of hydrostatic pressure applied during annealing on strain state of layers as well as on hexagonal MnAs inclusions was found. Pressure induced strain of inclusions is related
Increased PDGFRA signaling is an essential pathogenic factor in many subtypes of gliomas. In this context the cell surface expression of PDGFRA is an important determinant of ligand sensing in the glioma microenvironment. However, the regulation of spatial distribution of PDGFRA in glioma cells remains poorly characterized. Here, we report that cell surface PDGFRA expression in gliomas is negative
In this paper, a novel detection scheme for the monitoring of insect ecosystems is presented. Our method is based on the remote acquisition of passive sunlight scattering by two insect species. Procedures to identify rare events in remote dark-field spectroscopy are explained. We further demonstrate how to reduce the spectral representation, and how to discriminate between sexes, using a hierarchi
This thesis investigates Swedish intonation patterns and their interaction with word accent realisation in various pragmatic conditions, using German as a reference language. The point of departure is the wide-spread assumption that Swedish, as a language with a tonal word accent distinction, has a considerably smaller repertoire of nuclear intonation contours than German and other so-called inton
Our knowledge about acute promyelocytic leukemia (APL) patients is mainly based on data from clinical trials, whereas population-based information is scarce. We studied APL patients diagnosed between 1997 and 2006 in the population-based Swedish Adult Acute Leukemia Registry. Of a total of 3897 acute leukemia cases, 3205 (82%) had non-APL acute myeloid leukemia (AML) and 105 (2.7%) had APL. The in
Mammography screening can reduce breast cancer mortality. The aim of the present study was to investigate non-attendance in mammography screening in relation to different aspects of a women's social network, attitudes and cancer in close relations.
Immunocytochemistry for transactive response binding protein-43 (TDP43) was assessed in the granular cell layer of the dentate gyrus in 250 cases displaying hippocampal pathology identified by haematoxylin-eosin staining. 18%, nearly one in five displayed TDP43 immunoreactive pathology in the granular cell layer of hippocampus. This percentage increased to 43% when only subjects with hippocampal p
There is an increasing amount of data suggesting that there are inherent epidemiological and pathophysiological, as well as psychosocial differences between men and women with heart failure (HF). These differences may be so profound that they warrant differences in management and treatment. Furthermore women have been greatly underrepresented in clinical HF treatment trials. The major aim of the s
Popular Abstract in Swedish Prostatacancer är en mycket vanlig form av cancer, och det har visats att cirka hälften av alla män över 70 år har tumör i prostata. Prostatacancer är ofta en latent form av cancer, vilket innebär att den sällan ger kliniska symtom förrän i ett framskridet stadium. Sedan PSA testet började användas på 90-talet har antalet diagnostiserade fall av prostatacancer blivit alProstate cancer is currently the most common form of cancer in Sweden. Currently, the only biomarker used in the clinic is serum PSA, and there is a great need for new biomarkers that may increase the diagnostic and prognostic information so that better predictions can be made, and treatment may be tailored. Here, we have investigated two proposed biomarkers microseminoprotein-β (MSMB) and cystein
Gas chromatography (GC) and mass spectrometry (MS) were used to determine the stereoisomeric compositions of 6,10,14-trimethylpentadecan-2-ol and 6,10,14-trimethylpentadecan-2-one in wing extracts from 17 Bicyclus butterfly species from different regions of Africa. All samples were purified using solid phase extraction (SPE). Since some species contained both alcohol and ketone, these were separat
This article describes Monte Carlo computer simulations comparing the performances of a conventional neutron three axis spectrometer (TAS) and a micro-TAS, a mu TAS, designed to be as compact as seems practical. The simulations show that the mu TAS delivers performance (intensity at equal resolution) equivalent to that of a normal TAS. The mu TAS should be very cheap to build and a "farm" of sever

This is a short account of Danish history from the viking age until 1658. The Skåne provinces, lost to Sweden in 1658, have often been abscent in Danish histories, and in Sweden, their Danish history is also often forgotten. This books gives them place within a traditional narrative of Danish history.
