mer-Triaqua(1,10-phenanthroline-κ2 N,N′)(sulfato-κO)magnesium(II)
In the title compound, [Mg(SO4)(C12H8N2)(H2O)3], the MgII centre exhibits a slightly distorted octahedral coordination environment defined by two N atoms from a 1,10-phenanthroline molecule, one O atom from a sulfate dianion and three meridionally arranged O atoms from coordinated water molecules. The crystal structure involves intra- and intermolecular O—H⋯O hydrogen bonds
Historical Review about Research on “Bonghan System” in China
The meridian-collateral theory is the theoretical basis of acupuncture-moxibustion therapy. Professor Bonghan Kim, a professor of the Pyongyang Medical University of the Democratic People’s Republic of Korea, claimed that he found the anatomical structure of meridian-collaterals, named Bonghan corpuscles (BHCs) and Bonghan ducts (BHDs) system or primo vascular system (PVS), in 1962. From 1963 to 1965, researchers from our institute conducted a series of comparative anatomical experiments, trying to reproduce the so-called BHC- and BHD-like structures in different strains of animals. In the present paper, the authors introduced their research findings about BHC- and BHD-like structures in the young rabbit’s umbilicus including its external appearance, ectoplasm and endoplasm, and about strip-like and node-like objects in the blood vessels and lymph vessels near the larger abdominal and cervical blood vessels and chromaffin tissue in the back wall of the rabbit’s abdominal cavity and between the bilateral kidneys. In spite of existence of the BHC- and BHD-like structures in the rabbit, there has been no proved evidence for their association with the meridian-collateral system described in acupuncture medicine. In the present historical review, the authors also make a discussion about the significance of those findings
General formalism of Hamiltonians for realizing a prescribed evolution of a qubit
We investigate the inverse problem concerning the evolution of a qubit
system, specifically we consider how one can establish the Hamiltonians that
account for the evolution of a qubit along a prescribed path in the projected
Hilbert space. For a given path, there are infinite Hamiltonians which can
realize the same evolution. A general form of the Hamiltonians is constructed
in which one may select the desired one for implementing a prescribed
evolution. This scheme can be generalized to higher dimensional systems.Comment: 6 page
