In this account the authors’ latest results in C–C coupling catalysis are reviewed. First, an efficient catalytic system for the Kumada–Tamao–Corriu coupling reaction based on NHC-phosphine (NHC = N-heterocyclic carbene) nickel complexes is presented. Then the use of palladium complexes of chiral ferrocenyl NHC-phosphines in the asymmetric Suzuki–Miyaura coupling reaction is reported. High cata...

It is shown that at a 100 TeV muon collider the synchrotron radiation in the ring will determine the minimum horizontal emittance. In all ee storage ring the horizontal emittance is determined by quantum nature of the synchrotron radiation. Emission of photons in regions with non-zero dispersion leads to growth of the horizontal emittance while the average energy loss leads to the cooling. As t...

As we have reported at the last SRF Workshop two years ago, staged transition of the Cornell Electron Storage Ring (CESR) RF System from normal conducting to superconducting was completed in September 1999 with installation of the fourth superconducting B-cell cavity [1]. Since that time the last cavity has been commissioned and RF system has operated stably providing CESR beams with up to 1.13...

The cardinal symptom of acute encephalopathy is impairment consciousness onset during the course an infectious disease, with duration and severity meeting defined criteria. Acute consists multiple syndromes such as necrotizing encephalopathy, biphasic seizures late reduced diffusion clinically mild encephalitis/encephalopathy reversible splenial lesion. Among these syndromes, there are both sim...

Optically active -arylalkylamines are an important class of compounds that are widely used in organic and pharmaceutical synthesis, and much effort has been made to develop efficient asymmetric synthetic methods for them.[1] Asymmetric catalytic hydrogenation of enamides, initiated by Kagan et al. ,[2] provides a direct and convenient route to chiral amine derivatives. However, many well-known ...

BACKGROUND & AIMS It remains unknown what the prevalence of minimal hepatic encephalopathy is in Taiwan, a highly endemic country for chronic viral hepatitis infection. It is also unclear whether abnormal serum cytokine levels can be indicative of the presence of minimal hepatic encephalopathy. We aimed to standardize the tests of psychometric hepatic encephalopathy score and predictive value o...

We compute and investigate four types of imprint of a stochastic background of primordial magnetic fields (PMFs) on the cosmic microwave background (CMB) anisotropies: the impact of PMFs on the CMB temperature and polarization spectra, which is related to their contribution to cosmological perturbations; the effect on CMB polarization induced by Faraday rotation; the impact of PMFs on the ioniz...
