Atlantic Ocean circulation jump-start world
2019/10/18
A key question for climate scientists in recent years has been whether the Atlantic Ocean's main circulation system is slowing down, a development that could have dramatic consequences for Europe and ...
Temperature Dependence of Electron Transfer to the M-Side Bacteriopheophytin in Rhodobacter capsulatus Reaction Centers
hydrogenation fatty acids stereoselectivity kinetics
2016/5/25
Subpicosecond time-resolved absorption measurements at 77 K on two reaction center (RC) mutants of Rhodobacter capsulatus are reported. In the D(LL) mutant the D helix of the M subunit has been substi...
High Yield of M-Side Electron Transfer in Mutants of Rhodobacter Capsulatus Reaction Centers Lacking the L-Side Bacteriopheophytin
Rhodobacter capsulatus Pheophytins Detergents Spectrum Analysis Oxidation-Reduction Mutation Plasmids Amino Acid Sequence Molecular Sequence Data Histidine
2016/5/24
We present studies on a series of photosynthetic reaction center (RC) mutants created in the background of the Rhodobacter capsulatus D(LL) mutant, in which the D helix of the M subunit has been subst...
Mg Coordination by Amino Acid Side Chains is Not Required for Assembly and Function of the Special Pair in Bacterial Photosynthetic Reaction Centers
Amino Acids Fourier Analysis Light-Harvesting Protein Complexes Magnesium xidation-Reduction Photosynthetic Reaction Center Complex Proteins Spectrometry,Fluorescence Spectrum Analysis, Raman
2016/5/23
A conserved histidine serves as the axial ligand to the Mg of bacteriochlorophylls in the photosynthetic reaction center (RC) and many other photosynthetic systems. The histidine axial ligands to each...

2015/9/8
The Albano Lake is the deepest volcanic lake among the volcanoes located in the Italian peninsula.
It belongs to the Colli Albani volcanic complex whose last largest eruptions are dated back to about...
Supply-Side Ecology and the Response of Zooplankton to Climate-Driven Changes in North Atlantic Ocean Circulation
Response of Zooplankton Supply-Side Ecology
2015/7/29
Recent findings from oceanographic field studies conducted on both sides of the North Atlantic have dramatically altered our view of how zooplankton populations respond to climate-driven changes in oc...

2012/4/17
A new applicable wiretap channel with separated side information is considered here which consist of a sender, a legitimate receiver and a wiretapper. In the considered scenario, the links from the tr...
Self-injection-locked magnetron as an active ring resonator side coupled to a waveguide with a delayed feedback loop
delayed feedback loop Self-injection-locked
2011/8/26
The theoretical analysis and numerical simulations of the magnetron operation with a feedback loop were performed assuming that the delay of the electromagnetic wave propagating in the loop is constan...
Abstract: We analyze conformal blocks with multiple (semi-)degenerate field insertions in Liouville/Toda conformal field theories an show that their vector space is fully reproduced by the four-dimens...
Paraxial theory of sum-frequency generation by side-walk alignment and phase-matching in uniaxial crystals
