Multiple cranial nerve neuropathies, microcephaly, neurological degeneration, and “fork and bracket sign” in the MRI: A distinct syndrome
Authors: Mégarbané André , Dorison Nathalie , Rodriguez Diana , Tamraz Jean 
Published: July 2010

AbstractWe report on two sibs with an elongated face with reduced expression, microcephaly, strabismus, wide philtrum, mild joint laxity, thumb sign, bilateral foot drop, and fixed pes cavus, absent tendinous reflexes, an unsteady gait, quick fatigue, slightly diminished limb muscle strength more pronounced distally, abnormalities of cranial nerves III, IV, VII, and most probably VI, and slowness in ideation. Previously unknown findings referred to as the “fork sign” at the pontine level and the “bracket sign” at the mesencephalic level were documented by magnetic resonance imaging. Differential diagnoses and the possibility of a hitherto unreported syndrome are discussed. © 2010 Wiley‐Liss, Inc.
Run‐to‐Run Optimization of Fed‐Batch Fermentation for Ethanol Production
Authors: Huang W.‐H. , Shieh G. S. , Wang F.‐S. 
Published: July 2010

AbstractA two‐stage design approach is introduced to determine the optimal feed rate, fed glucose concentration and fermentation time to maximize ethanol productivity by using Saccharomyces diastaticus LORRE 316. The first stage is applied to determine a kinetic model using batch time‐series data. Two runs were carried out in the second stage to achieve the maximum ethanol production rate for the fed‐batch fermentation process. The computational results from the kinetic model using batch and fed‐batch time‐series data are in better agreement with the fed‐batch experiments than those from the kinetic model using batch time‐series data. For cross‐validation, an extra fed‐batch experiment with constant feed rate was carried out for comparison with the optimal fed‐batch result. According to the experimental results, this optimal approach was able to improve productivity by at least 12.56 % compared with that using the constant feed rate.
Mesomorphic Hydrogen‐Bonded Complexes of Complementary Semiperfluorinated Components
Authors: Kohlmeier Alexandra , Janietz Dietmar 
Published: July 2010

Abstract2,4‐Diamino‐6‐phenyl‐1,3,5‐triazines carrying one or two semiperfluorinated chains at the phenyl substituent have been investigated in binary mixtures with partially fluorinated benzoic acids by polarizing microscopy, differential scanning calorimetry, and X‐ray diffraction. The number and positions of the fluorinated tails of the acid component were systematically modified. Equimolar mixtures of the triazines with the aromatic acids form discrete hydrogen‐bonded heterodimers with an elongated central core. Mesomorphic properties are observed only if at least three terminal fluoroalkyl chains are grafted to the hydrogen‐bonded rigid core. The dimeric supermolecules exhibit columnar mesophases with rectangular or oblique two‐dimensional lattice symmetry or bicontinuous cubic phases. The mesophases of the dimers are ribbon phases resulting from the collapse of smectic layers. Thereby, the phase type is defined by the number and positions of the fluorinated tails of the two components. Docking of two or three equivalents of two‐chain benzoic acids to the diaminotriazine core leads to the formation of cylindrical aggregates, which organize into hexagonal columnar phases, whereas 1:2 and 1:3 mixtures of the two‐chain triazine with a three‐chain fluorinated aromatic acid display micellar cubic phases.

Abstract2,6‐Bis(1,2,3‐triazol‐4‐yl)pyridine (btp) ligands with substitution patterns ranging from strongly electron‐donating to strongly electron‐accepting groups, readily prepared by means of Cu‐catalyzed 1,3‐dipolar cycloaddition (the “click” reaction), were investigated with regard to their complexation behavior, and the properties of the resulting transition‐metal compounds were compared. Metal–btp complexes of 1:1 stoichiometry, that is, [Ru(btp)Cl2(dmso)] and [Zn(btp)Br2], could be isolated and were crystallographically characterized: they display octahedral and trigonal‐bipyramidal coordination geometries, respectively, and exhibit high aggregation tendencies due to efficient π–π stacking leading to low solubilities. Metal–btp complexes of 1:2 stoichiometry, that is, [Fe(btp)2]2+ and [Ru(btp)2]2+, could also be synthesized and their metal centers show the expected octahedral coordination spheres. The iron compounds exhibit quite a complex magnetic behavior in the solid state including spin crossover near room temperature, and hysteresis and locking into high‐spin states on tempering at 400 K, depending on the substituents on the btp ligands. Cyclic voltammetry studies of [Ru(btp)2]2+ reveal strong modulation of the oxidation potentials by more than 0.6 V and a clear linear correlation to the Hammett constant (σpara) of the substituent at the pyridine core. Isothermal titration calorimetry was used to measure the thermodynamics of the FeII–btp complexation process and enabled accurate determination of the complexation enthalpies, which display a linear relationship with the σpara values for the terminal phenyl substituents. Detailed NMR spectroscopic studies finally revealed that in the case of FeII complexation, dynamics are rapid for all investigated btp derivatives in acetonitrile, while replacing FeII by RuII or changing the solvent to dichloromethane effectively slows down ligand exchange. The results nicely demonstrate the utility of substituent parameters, originally developed for linear free‐energy relationships to explain reactivity in organic reactions, in coordination chemistry, and to illustrate the potential to custom‐design btp ligands and complexes thereof with predictable properties. The fast equilibration of the [Fe(btp)2]2+ complexes together with their tunable stability and interesting magnetic properties should enable the design of dynamic metallosupramolecular materials with advantageous properties.
Slow Magnetic Relaxation from Hard‐Axis Metal Ions in Tetranuclear Single‐Molecule Magnets

Published: July 2010

AbstractWe report the synthesis of the novel heterometallic complex [Fe3Cr(L)2(dpm)6]⋅Et2O (Fe3CrPh) (Hdpm=dipivaloylmethane, H3L=2‐hydroxymethyl‐2‐phenylpropane‐1,3‐diol), obtained by replacing the central iron(III) atom by a chromium(III) ion in an Fe4 propeller‐like single‐molecule magnet (SMM). Structural and analytical data, high‐frequency EPR (HF‐EPR) and magnetic studies indicate that the compound is a solid solution of chromium‐centred Fe3Cr (S=6) and Fe4 (S=5) species in an 84:16 ratio. Although SMM behaviour is retained, the |D| parameter is considerably reduced as compared with the corresponding tetra‐iron(III) propeller (D=−0.179 vs. −0.418 cm−1), and results in a lower energy barrier for magnetisation reversal (Ueff/kB=7.0 vs. 15.6 K). The origin of magnetic anisotropy in Fe3CrPh has been fully elucidated by preparing its Cr‐ and Fe‐doped Ga4 analogues, which contain chromium(III) in the central position (c) and iron(III) in two magnetically distinct peripheral sites (p1 and p2). According to HF‐EPR spectra, the Cr and Fe dopants have hard‐axis anisotropies with Dc=0.470(5) cm−1, Ec=0.029(1) cm−1, Dp1=0.710(5) cm−1, Ep1=0.077(3) cm−1, Dp2=0.602(5) cm−1, and Ep2=0.101(3) cm−1. Inspection of projection coefficients shows that contributions from dipolar interactions and from the central chromium(III) ion cancel out almost exactly. As a consequence, the easy‐axis anisotropy of Fe3CrPh is entirely due to the peripheral, hard‐axis‐type iron(III) ions, the anisotropy tensors of which are necessarily orthogonal to the threefold molecular axis. A similar contribution from peripheral ions is expected to rule the magnetic anisotropy in the tetra‐iron(III) complexes currently under investigation in the field of molecular spintronics.

Published: July 2010

AbstractRecent experiments in LHD have demonstrated reactor‐relevant high β plasmas. The high beta state with the volume averaged beta of 5 % has been maintained for longer than 100 times the energy confinement time without any disastrous instability. Accumulated data and extended knowledge is a firm basis for a reactor assessment as well as comprehensive physics understanding of high β plasmas. This article addresses highlighted issues from the latest experimental observations in the LHD experiment, which are related to reconfirmation of gaps in non‐dimensional parameters, characteristics of growth of MHD instabilities, effects of stochastic magnetic field and resonant magnetic perturbation, and transport associated with a resistive interchange mode (© 2010 WILEY‐VCH Verlag GmbH & Co.

AbstractDynamic magnetic configuration scan experiments have been conducted in order to investigate the influence of the rotational transform on plasma rotation, radial electric field and turbulence. The main magnetic resonances (7/4 and 5/3 in this work) make a positive contribution to the local radial electric field, which depends on the plasma density and plasma radius. A local reduction in the level of density fluctuations due to the influence of low order rational surfaces is also observed. These results could explain local transport changes associated to low order rational surfaces observed in TJ‐II ECH plasmas (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractIn Heliotron J, low magnetic shear configuration, instabilities with frequency chirping in the frequency range of Alfvén eigenmodes have been observed in tangentially injected neutral beam plasmas. These modes are induced by energetic‐particle driven magnetohydrodynamic (MHD) instabilities such as global Alfvén eigenmode or energetic particle mode. A hybrid directional Langmuir probe system has been installed into Heliotron J to investigate the response of fast‐ion fluxes to the MHD modes. A high coherent response of the ion flux to the bursting modes has been observed not only by the co‐directed probe but also by the counter‐directed one. A linear correlation between the response of the co‐directed ion flux and the mode amplitude has been found. The radial profile of the response of the co‐directed ions has decreased with the minor radius and has not been obtained significantly outside last closed flux surface. These results indicate that the fast‐ion response is due to a resonant convective oscillation. The ion flux response of the counter‐directed probe has appeared in the growth phase of the mode burst. Its phase relation is different from that of co‐directed one and magnetic probe located at the Heliotron J vacuum vessel. Two candidates of the detected ion flux of the counter‐directed probe have been discussed (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractA core density collapse (CDC) phenomenon is a rapid collapse events observed in super dense core (SDC) plasma with internal diffusion barrier (IDB) in the Large Helical Device (LHD). By CDC, the central beta is decreased by up to 50%. The collapse starts from the edge region of the plasma. CDCs appear with plasma parameters where the high–n ballooning modes are unstable at ϱ ∼ 0.8. With less collisional conditions, m = 1 type oscillations are observed with similar beta profile. The origin of the m = 1 oscillations is not clarified (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
