15 compounds, including two new ones crepidatuols A (1) and B (2) were isolated from the stems of Dendrobium crepidatum. The planar structures of these compounds were elucidated by spectroscopic methods (NMR, MS, UV, and IR) and comparison with those from literatures. 10 compounds were send for enhancing activities on nerve growth factor (NGF) medicated neurite outgrowth in PC12 cells and the results indicated that crepidatuol A (1), confusarin and 3-(2-acetoxy-5-methoxy)-phenylpropanol showed enhancing activities at the concentration of 10.0 µM.

Measurement-Device-Independent Quantum Key Distribution over Untrustful Metropolitan Network

Quantum cryptography holds the promise to establish an information-theoretically secure global network. All field tests of metropolitan-scale quantum networks to date are based on trusted relays. The security critically relies on the accountability of the trusted relays, which will break down if the relay is dishonest or compromised. Here, we construct a measurement-device-independent quantum key distribution (MDIQKD) network in a star topology over a 200-square-kilometer metropolitan area, which is secure against untrustful relays and against all detection attacks. In the field test, our system continuously runs through one week with a secure key rate 10 times larger than previous results. Our results demonstrate that the MDIQKD network, combining the best of both worlds-security and practicality, constitutes an appealing solution to secure metropolitan communications.

“…Vernazza et al (1981) have already shown that A&A 539, A49 (2012) dominant chromospheric coolants are hydrogen, plus singly ionized calcium and magnesium. For prominences, calcium losses were computed by Zhang & Fang (1987), who found them to be negligible compared to hydrogen for some specific models. Because this contradicts the results found in the chromosphere, we recompute here the calcium losses in prominences, using the most up-to-date radiative transfer models (Gouttebroze & Heinzel 2002).…”

Aims. We reconsider the question which kinetic temperatures can lead to prominence configurations that are in radiative equilibrium. We compare these temperatures to those from other calculations. Methods. For this purpose we solved the full non-LTE radiative-transfer problem for a gas consisting of hydrogen, helium and calcium. We used simple isobaric 1D slabs and began with isothermal models. Then we solved the radiative-relaxation problem and determined the radiative-equilibrium conditions within the whole slab. Results. By adding the calcium radiative losses, we found that these equilibrium temperatures are considerably lower than those obtained for a pure hydrogen gas. This is because the newly calculated CaII line losses appear to play a significant role in the energy balance, similar to chromospheric conditions. The equilibrium temperatures obtained span the range between 4400−9500 K, depending on the gas pressure and slab thickness.
