X-ray ptychography is often implemented for nanoimaging at synchrotron radiation sources and extensions are being developed to make experiments faster. This work is on multi-beam ptychography with Fresnel zone plates that have a small lateral separation, enabling the imaging of an extended field of view without increasing exposure time. Sectional zone inversion is implemented for coding respective
An overview of optical techniques for environmental monitoring is presented. Range-resolved measurements of atmospheric pollutants can be performed using the differential absorption lidar technique. Fluorescence lidar allows assessment of vegetation status and also the conditions of the facades of historical buildings. Diode lasers provide particularly realistic schemes for atmospheric gas analysi
ObjectivesPeople with serious illness approaching end of life often end up in emergency and hospital care, frequently against expressed preferences. Consequently, oncology trials record care days as a measure of treatment burden called “time toxicity.” However, this measure ignores the diminishing marginal utility of time: that the value of a day is higher when fewer remain. We aimed to incorporat
A study is presented of the impact on science data from extremely large telescopes of a transformation of wavelength base for optimization of actuator architecture from 2 200 to 1250 nm. From the optical path difference (OPD) data for Euro50, we transform to E-ELT OPDs. We compute the corresponding power spectrum, in which we simulate a higher actuator density via high-pass filtering to convert fr
Between 1991 and 1994 the number of beds in the surgical clinic at a central hospital in Southern Sweden was cut back by almost 50%. To develop the nursing care and to control the effects of the budgetary cuts, an intervention, including nursing care development, of an organization that would secure continuity in the nurse-patient relationship, individually planned care and quality assurance for a
In the pulp and paper industry, about 5 Mt/y chemithermomechanical pulp (CTMP) are produced globally from softwood chips for production of carton board grades. For tailor making CTMP for this purpose, wood chips are impregnated with aqueous sodium sulphite for sulphonation of the wood lignin. When lignin is sulphonated, the defibration of wood into pulp becomes more selective, resulting in enhance
This paper estimates a "Grossman" model of demand for health. We measure health status on a 0 (dead) to 1 (full health) cardinal scale by the rating scale method and the time trade-off method. We also use a categorical measure of overall health status commonly used in quality of life measurements. To estimate the demand for health equations, the Tobit technique is used for the rating scale and tim
To meet complex needs in persons and families within specialist palliative care, care team members are expected to work together in performing a comprehensive assessment of patient needs. Team type (how integrated team members work) and team maturity (group development) have been identified as components in team effectiveness and productivity. The aim of the study reported in this paper was to ide
Today, innovation is a key word for many universities, as it constitutes an important part of most universities’ public and scientific interaction with society. Many universities are striving to increase the number of innovations spun out. At many universities, innovations are thought of as being sprung from research projects and generated by researchers. However, Sandström (2014) claims that whil
In this paper, we investigate the importance of taking frequency-dependent temporal phenomena into account in audio coding. We do this in the context of sinusoidal modeling of audio signals by applying amplitude modulation to the sinusoidal components. Traditionally, audio coders use a fixed time-segmentation for all frequencies despite that it is well-known that the time-frequency resolution of t
Popular Abstract in Swedish Multikonjugerad Adaptiv Optik för Astronomiska Teleskop 1. Atmosfärisk turbulens Allt sedan man på 1600-talet började bruka optiska instrument inom astronomin, för att understödja det mänskliga ögat då man beskådade stjärnhimlen, har astronomer strävat efter att bygga allt större och bättre teleskop för att kunna se längre ut i rymden och skönja allt ljussvagare objekt.This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future. The first part is an introductory exposition on atmospheric turbulence, adaptive optics (AO) and MCAO, esta
Popular Abstract in Swedish Människor (och andra arter) har en grundläggande förmåga att anpassa sig till och lära sig hur omgivningen är strukturerad. Ofta lär vi oss struktur indirekt, utan att direkt och avsiktligt studera strukturen ifråga. Klassiska vardagsexempel på tämligen oavsiktlig strukturinlärning är språkinlärning, utveckling av musikaliska preferenser, inlärning av sociala regler, ocPeople can become sensitive to the general structure of different parts of the environment, often without studying that general structure directly, but through being incidentally exposed to instances that conform to the structure. When such learning proceeds unintentionally and gives rise to knowledge that is difficult to verbalize it is often referred to as implicit learning. One of the most comm
Duplicative horizontal gene transfer may bring two previously separated homologous genes together, which may raise questions about the interplay between the gene products. One such gene pair is the “native” PgiC1 and “foreign” PgiC2 in the perennial grass Festuca ovina. Both PgiC1 and PgiC2 encode cytosolic phosphoglucose isomerase, a dimeric enzyme whose proper binding is functionally essential.
