Using x-ray photoelectron spectroscopy, thermal desorption spectroscopy, and scanning tunneling microscopy, we show that upon keV Xe+ irradiation of graphene on Ir(111), Xe atoms are trapped under the graphene. Upon annealing, aggregation of Xe leads to graphene bulges and blisters. The efficient trapping is an unexpected and remarkable phenomenon given the absence of chemical binding of Xe to Ir
In this review, we summarize a series of experimental studies of the swelling of zwitterionic lamellar phospholipid and phospholipid-cholesterol systems using a novel double twin calorimeter. With this method, one can obtain simultaneous measures of the partial molar free energy and the partial molar enthalpy, and the experimental studies thus provide a complete thermodynamic characterization of t
Intra--arterial thrombolysis has become the most important minimal--invasive treatment option to treat acute lower limb ischemia. Although hemorrhagic stroke is a dreaded complication, it is considered beneficial to many fragile and elderly patients where vascular surgery is not an option. This review outlines current results after intra--arterial thrombolysis with low dose recombinant tissue plas
Diverse physiological processes are regulated differentially by Ca2+ oscillations through the common regulatory hub calmodulin. The capacity of calmodulin to combine specificity with promiscuity remains to be resolved. Here we propose a mechanism based on the molecular properties of calmodulin, its two domains with separate Ca2+ binding affinities, and target exchange rates that depend on both tar
Based on the Constructal Theory, parallel-flow and counterflow microchannels heat sinks with bifurcations are put forward to manage the temperature nonuniformity and further reduce the temperature of microchannel heat sinks bottom plates. Several models with different lengths of bifurcations are designed, and the corresponding laminar fluid flow and heat transfer of all models have been investigat
With rising concentrations of both atmospheric carbon dioxide (CO2) and tropospheric ozone (O-3), it is important to better understand the interacting effects of these two trace gases on plant physiology affecting land-atmosphere gas exchange. We investigated the effect of growth under elevated CO2 and O-3, singly and in combination, on the primary short-term stomatal response to CO2 concentration
The aim of this short article is to question the archaeological classification of the Neolithic archaeological cultures, and to raise questions about how to understand the fragmentary material culture in terms of social agency and cultural expression. e settlement of Jonstorp in southern Sweden as a case of the south Scandinavian Pitted Ware complex presents theoretical and methodological implicat
We discuss new diffractive mechanism of central exclusive production of W+W- pairs in proton-proton collisions at the LHC. We include diagrams with intermediate virtual Higgs boson as well as quark box diagrams. Several observables related to this process are calculated. Predictions for the total cross section and differential distributions in W-boson rapidity and transverse momentum as well as WW
Strong field laser-matter interaction is intrinsically a sub-cycle phenomenon, which is clearly illustrated by the generation of attosecond pulses through the high-order harmonic process. Therefore, to control strong field processes the structure of the field driving the generation has to be controlled on a sub-cycle level. One approach is to use phase stabilized few-cycle driving pulses and vary
In 2013, the Large Hadron Collider provided proton-lead and lead-proton collisions at the center-of-mass energy per nucleon pair root s(NN) = 5.02 TeV. Van der Meer scans were performed for both configurations of colliding beams, and the cross section was measured for two reference processes, based on particle detection by the T0 and V0 detectors, with pseudo-rapidity coverage 4.6 < eta < 4.9, -3.
Photography is a recognized medium to spread information about atrocities and to raise awareness about human rights issues. Photography is also widely used by political actors and social move- ments to construct an image of themselves and their causes. The political potential of photography is closely connected to the role of the visual in the public. The language of photography is at the same tim
This thesis presents experimental results on the development and optimization of novel and highly compact sources of beams of fast ions, relativistic electrons and coherent x-rays, driven by intense laser-plasma interactions. The rapid development of high-power, short-pulse laser systems have made available peak powers reaching the petawatt regime and focused intensities reaching 10^21 W/cm2. Whe
Popular Abstract in Swedish I avhandlingen presenteras nya teoretiska och experimentella metoder för att analysera spridning av elektromagnetiska vågor, framförallt med fokus på antenner och trådlös kommunikation. Oavsett det handlar om radio- och TV-sändningar, mobiltelefoni, trådlösa datornätverk, eller radar, så är antenner oumbärliga; de är nämligen länken mellan de elektromagnetiska vågorna oSum rules and physical limitations within electromagnetic theory and antenna theory have received significant attention in the last few years. However, the derivations are often relying on application specific and sometimes unsupported assumptions, and therefore a mathematically rigorous and generally applicable approach seems timely. Such an approach is presented in this thesis, along with exampl
Background: Increasing evidence about the high social and economic costs of poor mental health has contributed to a growing recognition of the need for health promotion interventions in mental health services. In spite of this, little empirical research has been performed investigating patients' attitudes to health promotion interventions. Aims: The aim of the present study was to investigate diff
