We present calculations for attosecond atomic delays in the photoionization of noble-gas atoms based on the full two-color two-photon random-phase approximation with exchange in both the length and velocity gauge. Gauge-invariant atomic delays are demonstrated for the complete set of diagrams. The results are used to investigate the validity of the common assumption that the measured atomic delays

AIMS: The present study sought to determine predictors for success and outcomes of patients who underwent cardiac implantable electronic devices (CIED) extraction indicated for systemic or local CIED related infection in particular where complete lead removal could not be achieved.METHODS AND RESULTS: ESC-EORP ELECTRa (European Lead Extraction ConTRolled Registry) is a European prospective lead ex

The purpose of this paper is to describe how Chinese national adolescent mental health policy is translated into local plans and practice by means of the theoretical perspective of the policy triangle. Document analysis of national, provincial andlocal policy documents and semi-structured interviews with local policy actors were performed. National policies were implemented by a top-down process.

Discussions of the sky in the Brontës’ works have tended to limit themselves to the weather, making Jane Eyre and Wuthering Heights seem very similar to one another in this regard. If, however, attention instead turns to the sky as a spatial phenomenon, there is a considerable difference between the two novels, symptomatic of a greater difference in the possibility of personal freedom. Thus, while

Transfusion-related acute lung injury (TRALI) is a life-threatening complication of acute respiratory distress occurring within 6 hours of blood transfusion. TRALI is one of the leading causes of transfusion-related fatalities and specific therapies are unavailable. Neutrophils are recognized as the major pathogenic cells, whereas T regulatory cells and dendritic cells appear to be important for p

The level of extracellular calcium has been demonstrated to regulate important physiological processes like cell growth and apoptosis. We demonstrate that in the bladder cancer cell line RT4, an increased extracellular calcium level induces apoptosis and that the HER1 receptor functions as a cell survival factor and delays apoptosis. After 12 h of calcium treatment (10 mM) apoptosis was detected i

Increased expression of the epidermal growth factor (EGF) receptors, HER1 and HER2 are related to poor prognosis in most cancers studied. Recently, a high expression of the two remaining receptors of the EGF system, HER3 and HER4 has been related to a favourable prognosis. However, prognostic significance of HER1 and HER2 receptors in bladder cancer is controversial and the effect of the expressio

In this essay it is argued that Bergman deviated from his highly critical depictions of bourgeois life in the films of the 1960s and 1970s, from Persona (1966) to the television series Scenes from a Marriage (1973), in Fanny and Alexander (1982), his final contribution to films made for the cinema. Bergman himself came from an upper-class bourgeois background, and by his own account he did not tak

Erfarenheterna från de amerikanska delstater som legaliserat cannabis visar att brottsligheten i princip inte påverkats alls. Forskningen visar också att insatser mot narkotikamarknaderna inte säkert skulle minska våldet. För att bekämpa gängvåldet bör insatserna i stället riktas mot våldet i sig, skriver forskarna Manne Gerell, Björn Johnson och Petter Karlsson.

What makes a business model successful? In this book the roots of business models are traced to the concept of the “business idea” which was popularized by researchers in the 1960s and 1970s. The business idea stresses the importance of conformance between the market and the product system, as well as between the product system and the internal features of the firm.A distinguishing feature of the

A measurement of W± boson production in Pb+Pb collisions at sNN=5.02Te is reported using data recorded by the ATLAS experiment at the LHC in 2015, corresponding to a total integrated luminosity of 0.49nb-1. The W± bosons are reconstructed in the electron or muon leptonic decay channels. Production yields of leptonically decaying W± bosons, normalised by the total number of minimum-bias events and

The production cross-sections for W± and Z bosons are measured using ATLAS data corresponding to an integrated luminosity of 4.0 pb- 1 collected at a centre-of-mass energy s=2.76 TeV. The decay channels W→ ℓν and Z→ ℓℓ are used, where ℓ can be an electron or a muon. The cross-sections are presented for a fiducial region defined by the detector acceptance and are also extrapolated to the full phase

Most pathogens can infect a number of different host species, but host species often differ considerably in susceptibility to a given pathogen. In the case of zoonotic pathogens, natural hosts typically present little or no disease symptoms, while humans and other “spill-over” hosts often present severe symptoms. Differences in susceptibility do not only occur between natural and non-natural hosts
