Auth kind ias: same SAML attr API as auth kind xsuaa for easier migration Changed Removed and integrated former ctx-auth middleware into cds.auth middleware cds.log: cds.env.log.format = 'plain'|'json' allows to configure which built-in formatter is used. Defaults to json in production...
Moreover, the problem may also go deeper than that: Although intuitively such "average" hedge ratios converge to certain "expected hedge ratio", the way the model is implemented may fail. Namely, every time series has only one volatility estimate, which is an average volatility over time. ...
[36] who showed the Molecules 2016, 21, 401 11 of 17 The nanomorphology of CdS during the solvothermal synthesis is controlled by the thermodynamics and kinetics during the nucleation and growth of nanocrystals which in turn are determined by the temperature and the water/thiourea ratio used in...
CCD imagers typically require high driving voltages, which leads to high power consumption. Since the switching power is proportional to the frequency, it is more difficult to achieve high operation speeds. As an alternative, CMOS-type burst mode imagers first convert photogenerated charges into ...
Second, the fluorescent QDs have a large surface-to-volume ratio, which is favorable for modifying the surface with biomolecules to achieve better biocompatibility, low toxicity, and a higher quantum yield (QY) [9]. As can be seen from previous references [10,11], the QD surface often ...
Among the nanostructures studied for efficient CdS photocatalysts, monodimensional structures such as nanorods, nanowires, or nanofibers are reported to be beneficial for photoactivity because of the confinement effects along their radial dimension which favors a better charge carrier separation. These mono...
