A generalized version of the TROSY experiment allows the spin-state selective editing of the four multiplet components of N–H cross peaks of amide groups in proteins into four different subspectra, with no penalty in sensitivity. An improvement by Î2 in sensitivity results, if only two of the four multiplet components are selected. Use of the experiment for the measurement of JHN coupling const...

The synthesis and characterization of some new binuclear copper (II) complexes, based on the use of large, pyrole-containing macrocycles, the so called "expanded porphyrins", [Cu2(macrocycle)]+4 is described. Electron Spin Resonance (ESR) studies indicate a weak "half-field line", which is characteristic of the Cu(II)-Cu(II) dimer, is observed at about 1600G. The obser...

The principle of maximum entropy production (MEP) is the subject of considerable academic study, but has yet to become remarkable for its practical applications. A tale is told of an instance in which a spin-off from consideration of an MEP-constrained climate model at least led to re-consideration of the very practical issue of water-vapour feedback in climate change. Further, and on a more-or...

a Experiments with X-half-filter elements allow the separation of the resonances from protons bound and unbound to a spin X into different subspectra. This Communication presents a modified half-filter element where the filter delay is simultaneously used for chemical shift labeling and scalar coupling evolution in a semiconstant time experiment. The filter element is demonstrated with a H NOES...

For academic spin-offs I analyze the length of the time period between the founder’s leaving of academia and the establishment of her firm. A duration analysis reveals that a longer time-lag is caused by the necessity of assembling complementary skills, either by acquisition by a single founder or by searching for suitable teammembers. Furthermore, new ventures are established faster if there h...

The multiplequantum (MQ) evolution of anisotropic spin systems with four to eight coupled protons is analyzed using a computer for the basic three-pulse sequence. MQ intensities are first investigated as a function of preparation time. The concept of timeindependent intensities is then introduced, and an algorithm for efficient computation of these quantities is described. A correlation between...

objective: social anxiety disorder (sad) is defined as a constant fear of being embarrassed or negatively evaluated in social situations or while doing activities in the presence of others. several studies have examined the role of certain variables that might predict response to treatment and may affect treatment outcome. the purpose of this study was to identify predictive variables of change...

In the fabrication of silica films by sol-gel synthesis, the role of various catalysts is systematically examined. The precursor solutions were made by mixing tetraethylorthosilicate (TEOS), ethanol and water in the molar ratio of 1 : 2 : 2. The spin coated films were thermally treated at various temperatures, and characterised using ellipsometry, molecular probe ellipsometry (MPE), infrared sp...

Zeeman splitting of the ground state of single impurities in the quantum wells of resonant tunneling heterostructures is reported. We determine the absolute magnitude of the effective magnetic spin splitting factor g∗ ⊥ for a single impurity in a 44 Å Al0.27Ga0.73As/GaAs/Al0.27Ga0.73As quantum well to be 0.28 ± 0.02. This system also allows for independent measurement of the electron tunneling ...

The number of installations of the Spin model checking tool is steadily increasing. There are well over two thousand installations today, divided roughly evenly over academic and industrial sites. The tool itself also continues to evolve; it has more than doubled in size, and hopefully at least equally so in functionality, since it was rst distributed in early 1991. The tool runs on most standa...
