We present a simple and robust technique to retrieve the phase of ultrashort laser pulses, based on a chirped mirror and glass wedges compressor. It uses the compression system itself as a diagnostic tool, thereby making unnecessary the use of complementary diagnostic tools. We used this technique to compress and characterize 7.1 fs laser pulses from an ultrafast laser oscillator. (C)2011 Optical
Inspired by the works of Michel Foucault and Erling Sandmo, this article explores contemporary discourses of military violence against civilians from a genealogical perspective. The purpose is to shed light on the historicity of certain structures of knowledge, thoughts, politics and ethics that are fundamental for the ways in which military violence against civilians is put into words, interprete
Abstract Health studies have repeatedly used air temperature (Ta), sometimes adjusted for humidity, when analyzing the impact of weather on mortality. The aim of this study is to highlight the importance of mean radiant temperature (Tmrt) and its impact on heat related mortality. Tmrt is an essential meteorological parameter that influences the thermal comfort (heat load) of humans. It is useful w
A low-diversity Early Jurassic flora preserved in floodbasin siltstones of the Marburg Subgroup at Inverleigh Quarry in the Clarence-Moreton Basin, eastern Australia, is dominated by Allocladus helgei Jansson sp. nov., a conifer with denticulate leaves tentatively attributed to Araucariaceae. The assemblage also includes Rintoulia variabilis and Caytoniales, (Caytonia cucullata McLoughlin sp. nov.
Using fluorescence super-resolution microscopy we studied simultaneous spectral, spatial localization, and blinking behavior of individual 1D J-aggregates. Excitons migrating 100 nm are funneled to a trap appearing as an additional red-shifted blinking fluorescence band. We propose that the trap is a Frenkel exciton state formed much below the main exciton band edge due to an environmentally induc
The cross section for ep -> eb (b) over barX in photoproduction is measured with the H1 detector at the ep-collider HERA. The decay channel b (b) over bar -> eeX' is selected by identifying the semi-electronic decays of the b-quarks. The total production cross section is measured in the kinematic range given by the photon virtuality Q(2) <= 1 GeV2, the inelasticity 0.05 <= y <= 0.65 and the pseudo
Global climate change increases heat loads in urban areas causing health and productivity risks for millions of people. Inhabitants in tropical and subtropical urban areas are at especial risk due to high population density, already high temperatures, and temperature increases due to climate change. Air conditioning is growing rapidly, especially in South and South-East Asia due to income growth a
Authors such as Dryzek, Gough and Meadowcroft have indicated that social-democratic welfare states could be in a better position to deal with development of the ‘green’ or ‘eco’state, and the intersection of social and environmental policies, than conservative or liberal welfare regimes (synergy hypothesis). However, this hypothesis has as yet not been examined in comparative empirical research. B
Sexual conflict has been proposed to be a mediator of speciation but recent theoretical work, as well as empirical studies, suggests that sexual conflict may also be able to prevent speciation and to preserve genetic polymorphism within a species. Here, we develop a population genetic model and study the effects of sexual conflict in a polymorphic population. The morphs mate assortatively based on
Conditions experienced during embryonic development can have lasting effects, even carrying across generations. Most evidence for transgenerational effects comes from studies of female mammals, with much less known about egg-laying organisms or paternally-mediated effects. Here we show that offspring sex can be affected by the incubation temperature its father experiences years earlier. We incubat
Abstract in Undetermined Background: The performance of glaucoma diagnostic systems could be conceivably improved by the integration of functional and structural test measurements that provide relevant and complementary information for reaching a diagnosis. The purpose of this study was to investigate the performance of data fusion methods and techniques for simple combination of Standard Automate
Popular Abstract in Swedish Alzheimers sjukdom (eng. Alzheimer’s disease, AD) är den vanligaste orsaken till de- mens. Demens innebär en permanent sänkning av intellektuella förmågor som påverkar individen påtagligt i vardagen. Förekomsten av demenssjukdomar ökar betydligt efter 65 års ålder. AD är en långsamt progredierande sjukdom, som oftast börjar med försämrat närminne. Redan idag är AD en beBackground: Alzheimer’s disease (AD) is the most common cause of dementia. In order to have effect of future disease-modifying therapies for AD, the disease must be identified early, before the patients have developed dementia. Many patients with Mild Cognitive Impairment (MCI) have prodromal AD, but other causes for the syndrome are common. No diagnostic method can identify AD in patients with MC
A resonant enhancement of the water-(1)H relaxation rate at three distinct frequencies in the range 0.5-3MHz has been observed in a variety of aqueous biological systems. These so-called quadrupole (Q) peaks have been linked to a dipolar flip-flop polarization transfer from (1)H nuclei to rapidly relaxing amide (14)N nuclei in rotationally immobilized proteins. While the Q-peak frequencies conform
The so-called New Passive in Icelandic takes the form 'it was elected us' (or, e.g., 'then was elected us', without an expletive), instead of the standard passive form 'we were elected'. It has neither A-movement to subject nor acc-to-nom conversion, which are otherwise diagnostic of the canonical passive in Icelandic and related languages. Some researchers have argued that "passive" is in fact a

The question of who appropriates the economic rents created by resources and capabilities has remained largely unresolved in strategic management. The aim of this paper is to highlight the problem established strategic management theory faces in explaining value appropriation, and to propose a framework that addresses how R&C affect bargaining power and value appropriation. While resource-base
