Continuously wavelength-tunable high harmonic generation via soliton dynamics
, 2017 We report generation of high harmonics in a gas-jet pumped by pulses self-compressed in a He-filled hollow-core photonic crystal fiber through the soliton effect. The gas-jet is placed directly at the fiber output.

On harmonic and asymptotically harmonic Finsler manifolds
Annals of the Alexandru Ioan Cuza University - MathematicsIn the present paper we introduce and investigate some types of harmonic Finsler manifolds and find out the interrelation between them. We give some characterizations of such spaces in terms of the Finsler mean curvature of geodesic spheres and the Finsler Laplacian of the distance function induced by the Finsler metric.

Advanced Functional Materials, EarlyView.Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

Advanced Functional Materials, EarlyView.A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Reed Selection and Sound Quality of an Alto Saxophone
International Scholastic Journal of Science, 2016 To investigate the relationship between reed stiffness and sound quality, the same note (concert Bb)was played on an alto saxophone with six different reeds (1.5, 2, 2.5, 3, 3.5, and 4). The relative amplitudes of the first four harmonics for each of the

Harmonization: Consumer Protection
, 2014 This contribution gives an overview of law and economic works on consumer protection. It does so by taking three complementary angles: (1) assessing harmonization efforts regarding consumer protection in Europe, (2) presenting selected topics of substantive consumer law, and (3) analyzing the European consumer law enforcement from an economic point of ...
