Ultrafast supercontinuum generation in gas-filled waveguides is an enabling technology for many intriguing applications ranging from attosecond metrology towards biophotonics,with the amount of spectral broadening crucially depending on the pulse dispersion of the propagating *** this study,we show that structural resonances in a gas-filled antiresonant hollow core optical fiber provide an additional degree of freedom in dispersion engineering,which enables the generation of more than three octaves of broadband light that ranges from deep UV wavelengths to near *** observation relies on the introduction of a geometric-induced resonance in the spectral vicinity of the ultrafast pump laser,outperforming gas dispersion and yielding a unique dispersion profile independent of core size,which is highly relevant for scaling input *** a krypton-filled fiber,we observe spectral broadening from 200 nm to 1.7μm at an output energy of B 23μJ within a single optical mode across the entire spectral *** show that the frequency generation results from an accelerated fission process of solitonlike waveforms in a non-adiabatic dispersion regime associated with the emission of multiple phase-matched Cherenkov radiations on both sides of the *** effect,along with the dispersion tuning and scaling capabilities of the fiber geometry,enables coherent ultra-broadband and high-energy sources,which range from the UV to the mid‐infrared spectral range.

Background: Cardiovascular rehabilitation in Germany traditionally is offered as inpatient service often located far from patient’s residence, and ambulatory rehabilitation still represents a minority. The German Registry of Ambulatory Cardiac Rehabilitation (KARREE) was designed to contribute to rehabilitation quality assurance and to evaluate clinical characteristics of patients participating in ambulatory rehabilitation centers. Methods: In four ambulatory rehabilitation centers 2989 patients were consecutively registered from 2008 to 2011 and evaluated with respect to social status, cardiovascular diagnoses and risk factors, psychological status, medication and short term clinical and social outcome. Results: Most patients referred to the ambulatory cardiac rehabilitation had an acute cardiovascular event, with patients after acute coronary syndrome representing the majority (59.9%). Female were strongly underrepresented (16.7%). Patient’s clinical characteristics varied with the age groups evaluated ( 70 years). Whereas the reported physical inactivity, overweight and cigarette smoking was declining with age, diabetes and hypertension significantly increased. Furthermore the reported and evaluated psychosocial stress was declining with age. Regarding the group of patients still employed, 43.5 % were estimated as fit for work directly at the end of the rehabilitation program, whereas a stepwise reintegration into employment was performed in 16.7%. The majority of patients were transferred to ambulatory heart groups or other forms of after care for stabilizing regular physical activity. Conclusions: The large variation of the characteristics of patients participating cardiac rehabilitation underscore the need of an individualized approach for a successful implementation of secondary prevention and reintegration of these patients into their social life.

The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,plays an important role in various analyses performed at the Large Hadron Collider,as Standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced *** paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collaboration,using √s=13 TeV proton–proton collision data with an integrated luminosity of 140 fb^(-1) collected by the ATLAS *** taggers with high performances in rejecting jets from gluon over jets from quarks are studied:one tagger is based on requirements on the number of inner-detector tracks associated with the jet,and the other combines several jet substructure observables using a boosted decision tree.A method is established to determine the quark/gluon fraction in data,by using quark/gluon-enriched subsamples defined by the jet *** in tagging efficiency between data and simulation are provided for jets with transverse momentum between 500 GeV and 2 TeV and for multiple tagger working points.
