Processing Visual Temporal Information and Its Relationship to Psychometric Intelligence
Authors: Haldemann Judith , Stauffer Corinne , Troche Stefan , Rammsayer Thomas
Published: October 2011

According to previous studies there is a well-established functional relationship between temporal resolution power (TRP), assessed by auditory psychophysical timing tasks, and psychometric intelligence. Here we investigated whether the relationship between psychometric intelligence and temporal information processing can be also observed in the visual modality. For this purpose, performance on four visual psychophysical timing tasks (duration discrimination with filled and empty intervals, temporal generalization, and rhythm perception) was examined and related to performance on a psychometric test of intelligence. Correlational analyses indicated a reliable positive association between performance on each of the four temporal tasks and psychometric intelligence. Structural equation modeling suggested that performance on the four tasks can be assigned to one latent variable, referred to as TRP, which explained 16.5% of variance of psychometric intelligence. Findings indicate that the functional relationship previously observed between auditory temporal processing and psychometric intelligence can be generalized to the visual modality.

RIG‐I detects cytosolic viral dsRNA with 5′ triphosphates (5′‐ppp‐dsRNA), thereby initiating an antiviral innate immune response. Here we report the crystal structure of superfamily 2 (SF2) ATPase domain of RIG‐I in complex with a nucleotide analogue. RIG‐I SF2 comprises two RecA‐like domains 1A and 2A and a helical insertion domain 2B, which together form a ‘C’‐shaped structure. Domains 1A and 2A are maintained in a ‘signal‐off’ state with an inactive ATP hydrolysis site by an intriguing helical arm. By mutational analysis, we show surface motifs that are critical for dsRNA‐stimulated ATPase activity, indicating that dsRNA induces a structural movement that brings domains 1A and 2A/B together to form an active ATPase site. The structure also indicates that the regulatory domain is close to the end of the helical arm, where it is well positioned to recruit 5′‐ppp‐dsRNA to the SF2 domain. Overall, our results indicate that the activation of RIG‐I occurs through an RNA‐ and ATP‐driven structural switch in the SF2 domain.

HAPE (high-altitude pulmonary oedema) is characterized by pulmonary hypertension, vasoconstriction and an imbalance in oxygen-sensing redox switches. Excess ROS (reactive oxygen species) contribute to endothelial damage under hypobaric hypoxia, hence the oxidative-stress-related genes CYBA (cytochrome b−245 α polypeptide) and GSTP1 (glutathione transferase Pi 1) are potential candidate genes for HAPE. In the present study, we investigated the polymorphisms −930A/G and H72Y (C/T) of CYBA and I105V (A/G) and A114V (C/T) of GSTP1, individually and in combination, in 150 HAPE-p (HAPE patients), 180 HAPE-r (HAPE-resistant lowland natives) and 180 HLs (healthy highland natives). 8-Iso-PGF2α (8-iso-prostaglandin F2α) levels were determined in plasma and were correlated with individual alleles, genotype, haplotype and gene–gene interactions. The relative expression of CYBA and GSTP1 were determined in peripheral blood leucocytes. The genotype distribution of −930A/G, H72Y (C/T) and I105V (A/G) differed significantly in HAPE-p compared with HAPE-r and HLs (P≤0.01). The haplotypes G-C of −930A/G and H72Y (C/T) in CYBA and G-C and G-T of I105V (A/G) and A114V (C/T) in GSTP1 were over-represented in HAPE-p; in contrast, haplotypes A-T of −930A/G and H72Y (C/T) in CYBA and A-C of I105V (A/G) and A114V (C/T) in GSTP1 were over-represented in HAPE-r and HLs. 8-Iso-PGF2α levels were significantly higher in HAPE-p and in HLs than in HAPE-r (P=2.2×10−16 and 1.2×10−14 respectively) and the expression of CYBA and GSTP1 varied differentially (P<0.05). Regression analysis showed that the risk alleles G, C, G and T of −930A/G, H72Y (C/T), I105V (A/G) and A114V (C/T) were associated with increased 8-iso-PGF2α levels (P<0.05). Interaction between the two genes revealed over-representation of most of the risk-allele-associated genotype combinations in HAPE-p and protective-allele-associated genotype combinations in HLs. In conclusion, the risk alleles of CYBA and GSTP1, their haplotypes and gene–gene interactions are associated with imbalanced oxidative stress and, thereby, with high-altitude adaptation and mal-adaptation.
Harmonic modulation behavior in lead lanthanum zirconate titanate ceramics
Authors: Georges Sabat Ribal
Published: October 2011

The transmission of light through a lead lanthanum zirconate titanate ceramic film, having a relaxor ferroelectric composition of (9.5/65/35), exhibited a Fabry-Pérot interference pattern. Upon the application of an electric field, the transmitted irradiance was modulated at both the first and second harmonic frequencies to that of the applied field. Large changes were observed in the optical path difference within the material due to a combination of the electrostrictive and quadratic electro-optic effects. A theoretical model was developed to obtain harmonic expressions for the Fabry-Pérot transmitted irradiance, and it was successfully fitted to the experimental results.
Energy dissipation in non-isothermal molecular dynamics simulations of confined liquids under shear
Authors: Berro Hassan , Fillot Nicolas , Vergne Philippe , Tokumasu Takashi , Ohara Taku , Kikugawa Gota
Published: October 2011

Energy is commonly dissipated in molecular dynamics simulations by using a thermostat. In non-isothermal shear simulations of confined liquids, the choice of the thermostat is very delicate. We show in this paper that under certain conditions, the use of classical thermostats can lead to an erroneous description of the dynamics in the confined system. This occurs when a critical shear rate is surpassed as the thermo-viscous effects become prominent. In this high-shear-high-dissipation regime, advanced dissipation methods including a novel one are introduced and compared. The MD results show that the physical modeling of both the accommodation of the surface temperature to liquid heating and the heat conduction through the confining solids is essential. The novel method offers several advantages on existing ones including computational efficiency and easiness of application for complex systems.
A general and efficient Monte Carlo method for sampling intramolecular degrees of freedom of branched and cyclic molecules
Authors: Shah Jindal K. , Maginn Edward J.
Published: October 2011

A simple and easily implemented Monte Carlo algorithm is described which enables configurational-bias sampling of molecules containing branch points and rings with endocyclic and exocyclic atoms. The method overcomes well-known problems associated with sequential configurational-bias sampling methods. A “reservoir” or “library” of fragments are generated with known probability distributions dependent on stiff intramolecular degrees of freedom. Configurational-bias moves assemble the fragments into whole molecules using the energy associated with the remaining degrees of freedom. The methods for generating the fragments are validated on models of propane, isobutane, neopentane, cyclohexane, and methylcyclohexane. It is shown how the sampling method is implemented in the Gibbs ensemble, and validation studies are performed in which the liquid coexistence curves of propane, isobutane, and 2,2-dimethylhexane are computed and shown to agree with accepted values. The method is general and can be used to sample conformational space for molecules of arbitrary complexity in both open and closed statistical mechanical ensembles.
Temperature dependence of the Landau-Placzek ratio in glass forming liquids
Authors: Popova V. A. , Surovtsev N. V.
Published: October 2011

Here, we studied Rayleigh-Brillouin light scattering in ten different glass-forming liquids (α-picoline, toluene, o-toluidine, ethanol, salol, glycerol, dibutyl phthalate, o-terphenyl, propylene carbonate, and propylene glycol). For each of these liquids it was found that the Landau-Placzek ratio is in a good agreement with the theory at high temperatures and significantly exceeds the theoretical prediction below a certain temperature. Transition between the two temperature regimes occurs near TA, where TA is crossover point from an Arrhenius-like to a non-Arrhenius behavior for the α-relaxation time dependence on temperature. Increase of the Landau-Placzek ratio relative to the theoretical prediction below TA seems to be the universal feature of glass-formers. We suggest that formation of locally favored structures in liquids below TA causes observed excess of the Landau-Placzek ratio.

Published: October 2011

Gallium metal under the freezing point was observed to maintain its liquid state by dispersing silica nanoparticles of a given particle size and concentration. Though the freezing point of pure gallium is 302.9 K, the liquid gallium maintained its supercooling state at 276-277 K for more than 400 days by dispersing 1.0 wt. % of silica nanoparticles (10 nm in size). Extended x-ray absorption fine structure analysis shows that the supercooled gallium liquid has a β-Ga-like feature, and the nearest neighboring atom distance is 0.1 Å larger than that of pure liquid gallium. This method opens the way to use liquid gallium as a promising fluid carrier in energy conversion devices.
Phase diagram of the uniaxial and biaxial soft–core Gay–Berne model
Authors: Berardi Roberto , Lintuvuori Juho S. , Wilson Mark R. , Zannoni Claudio
Published: October 2011

Classical molecular dynamics simulations have been used to explore the phase diagrams for a family of attractive–repulsive soft–core Gay–Berne models [R. Berardi, C. Zannoni, J. S. Lintuvuori, and M. R. Wilson, J. Chem. Phys. 131, 174107 (2009)] and determine the effect of particle softness, i.e., of a moderately repulsive short–range interaction, on the order parameters and phase behaviour of model systems of uniaxial and biaxial ellipsoidal particles. We have found that isotropic, uniaxial, and biaxial nematic and smectic phases are obtained for the model. Extensive calculations of the nematic region of the phase diagram show that endowing mesogenic particles with such soft repulsive interactions affect the stability range of the nematic phases, and in the case of phase biaxiality it also shifts it to lower temperatures. For colloidal particles, stabilised by surface functionalisation, (e.g., with polymer chains), we suggest that it should be possible to tune liquid crystal behaviour to increase the range of stability of uniaxial and biaxial phases (by varying solvent quality). We calculate second virial coefficients and show that they are a useful means of characterising the change in effective softness for such systems. For thermotropic liquid crystals, the introduction of softness in the interactions between mesogens with overall biaxial shape (e.g., through appropriate conformational flexibility) could provide a pathway for the actual chemical synthesis of stable room–temperature biaxial nematics.

Authors: Wu Xin , Chen Sihai , Chen Wei , Yang Minghui , Fu Wen
Published: October 2011

A large angle and high linearity two-dimensional laser scanner with an in-house ingenious deflection angle detecting system is developed based on voice coil actuators direct driving mechanism. The specially designed voice coil actuators make the steering mirror moving at a sufficiently large angle. Frequency sweep method based on virtual instruments is employed to achieve the natural frequency of the laser scanner. The response shows that the performance of the laser scanner is limited by the mechanical resonances. The closed-loop controller based on mathematical model is used to reduce the oscillation of the laser scanner at resonance frequency. To design a qualified controller, the model of the laser scanner is set up. The transfer function of the model is identified with MATLAB according to the tested data. After introducing of the controller, the nonlinearity decreases from 13.75% to 2.67% at 50 Hz. The laser scanner also has other advantages such as large deflection mirror, small mechanical structure, and high scanning speed.

Authors: Zubek Mariusz , Dampc Marcin , Linert Ireneusz , Neumann Tomasz
Published: October 2011

Electronic states of tetrahydrofuran molecules were studied in the excitation energy range 5.5–10 eV using the technique of electron energy loss spectroscopy in the gas phase. Excitation from the two conformations, C2 and Cs, of the ground state of the molecule are observed in the measured energy loss spectra. The vertical excitation energies of the 3(no3s) triplet state from the C2 and Cs conformations of the ground state of the molecule are determined to be 6.03 ± 0.02 and 6.25 ± 0.02 eV, respectively. The singlet-triplet energy splitting for the no3s configuration is determined to be 0.31 eV. It is also found that excitation from the Cs conformation of the ground state has a higher cross section than that from the C2 conformation.
Perturbation theory for multipolar discrete fluids
Authors: Benavides Ana L. , Gámez Francisco
Published: October 2011

An analytical expression for the Helmholtz free energy of discrete multipolar potentials as a function of density, temperature, and intermolecular parameters is obtained as an extension of the multipolar square-well perturbation theory [A. L. Benavides, Y. Guevara, and F. del Río, Physica A 202, 420 (1994)10.1016/0378-4371(94)90469-3]. The presented procedure is suitable for the description of a more general intermolecular potential model taking into account the overlap and dispersion forces through a discrete potential represented by a sequence of square-shoulders and wells, as well as electrostatic interactions. The main advantage of this approach is that since the Helmholtz free energy is given as an explicit expression in terms of the intermolecular parameters characterizing the interaction, the properties of interest can be easily obtained through usual thermodynamic relations. Besides, since a great variety of discretized potentials can be used with this equation of state, its applicability is very vast. By varying the intermolecular parameters, some illustrative cases are considered, and their phase diagrams are tested against available simulation data. It is found that this theoretical approach is able to reproduce qualitatively and quantitatively well the vapor-liquid equilibrium of the chosen potentials with different multipole moment of varied strengths, except in the critical region.
Nanoscale ferroelectric switching behavior at charged domain boundaries studied by angle-resolved piezoresponse force microscopy
Authors: Park Moonkyu , Hong Seungbum , Kim Jiyoon , Hong Jongin , No Kwangsoo
Published: October 2011

We investigated the effect of charged domain boundaries (CDBs) on the coercive voltage (Vc) in polycrystalline Pb(Zr0.25Ti0.75)O3 (PZT) thin films using angle-resolved piezoresponse force microscopy (AR-PFM). By using the AR-PFM technique, we could observe the detailed domain structure with various degrees of CDBs including neutral domain boundaries in the PZT thin films. We found that the Vc increases at CDBs induced by polarization discontinuities. We attribute the change in Vc to the built-in field created by uncompensated polarization charges at the CDBs in the PZT thin films.

We report on the achievement of high density (In,Ga)As self-assembled quantum dots on GaP substrate with a good homogeneity. Good structural and electronic properties have been achieved, as revealed by room temperature photoluminescence measurements and by comparison to both InAs/GaAs and InAs/InP materials reference systems. This is supported by atomistic calculations where the indium incorporation in InGaAs/GaP quantum structures is found to enhance both the type-I bandlineup and direct bandgap properties. The photoluminescence temperature dependence of the bandgap evidences the quantum confinement effects. Our results provide a valid framework to implement silicon optical devices based on InGaAs/GaP nanostructures.

Published: October 2011

We report the construction of two dimensional molecular dipole dot arrays with tunable dipole density via self-assembly of binary molecular system of dipolar molecule of chloroaluminium phthalocyanine (ClAlPc) with copper hexadecafluorophthalocyanine (F16CuPc) on graphite surface, as revealed by in situ low-temperature scanning tunneling microscopy experiments. The formation of multiple intermolecular C−H…F−C hydrogen bondings between the periphery F atoms on F16CuPc and H atoms on neighboring ClAlPc molecules can ensure structural rigidity and stability for potential applications in molecular nanodevices.
Subwavelength slow-light waveguides based on a plasmonic analogue of electromagnetically induced transparency
Authors: Huang Yin , Min Changjun , Veronis Georgios
Published: October 2011

We introduce a plasmonic waveguide system, based on a plasmonic analogue of electromagnetically induced transparency, which supports a subwavelength slow-light mode, and exhibits a small group velocity dispersion. The system consists of a periodic array of two metal-dielectric-metal (MDM) stub resonators side-coupled to a MDM waveguide. Decreasing the frequency spacing between the two resonances increases the slowdown factor and decreases the bandwidth of the slow-light band. We also show that there is a trade-off between the slowdown factor and the propagation length of the slow-light mode.

Published: October 2011

We report the demonstration of a one-dimensional waveguide for terahertz quantum-cascade (QC) lasers, which acts as a leaky-wave antenna and tailors laser radiation in one dimension to a directional beam. This scheme adapts microwave transmission-line metamaterial concepts to a planar structure realized in terahertz metal-metal waveguide technology. The active leaky-wave antenna is fed by a master oscillator QC-laser with a mode that propagates with an effective phase index smaller than unity, such that it radiates in the surface direction. The direction of emission of main beam is governed by the antenna dispersion characteristic. 25° of beam steering is observed as the lasing frequency of the QC-laser is varied from 2.65–2.81 THz.
Log-normal distribution of single molecule fluorescence bursts in micro/nano-fluidic channels
Authors: Kish Lazar L. , Kameoka Jun , Granqvist Claes G. , Kish Laszlo B.
Published: October 2011

The width and shape of photon burst histograms pose significant limitations to the identification of single molecules in micro/nano-fluidic channels, and the nature of these histograms is not fully understood. To reach a deeper understanding, we performed computer simulations based on a Gaussian beam intensity profile with various fluidic channel diameters and assuming (1) a deterministic (noise-free) case, (2) photon emission/absorption noise, and (3) photon noise with diffusion. Photon noise in narrow channels yields a Gaussian burst distribution while additional strong diffusion produces skewed histograms. We use the fluctuating residence time picture [J. Söderlund et al., Phys. Rev. Lett. 80, 2386 (1998)] and conclude that the skewness of the photon number distribution is caused by the longitudinal diffusive component of the motion of the molecules as they traverse the laser beam. In the case of strong diffusion in narrow channels, this effect leads to a log-normal distribution. We show that the same effect can transform the separate peaks of the photon burst histograms of multiple molecule mixtures into a single log-normal shape.
