description: We present a short review of our results on the collectivity and the suppression pattern of charmed mesons in heavy-ion collisions based on the microscopic Hadron-String Dynamics (HSD) transport approach for different scenarios of charm interactions with the surrounding matter - the 'comover' dissociation by mesons with further recreation by D+Dbar channels and 'pre-hadronic' interaction scenarios. While at SPS energies the hadronic 'comover' absorption scenario is found to be compatible with the experimental data, the dynamics of c and cbar quarks at RHIC are dominated by partonic or 'pre-hadronic' interactions in the strongly coupled quark-gluon plasma stage and cannot be modeled by pure hadronic interactions. We find that the collective flow of charm in the purely hadronic scenario appears compatible with the data at SPS energies but underestimates the data at top RHIC energies. Thus, the large elliptic flow v2 of D mesons and the low R_AA(pT) of J/Psi seen experimentally at RHIC have to be attributed to early interactions of non-hadronic degrees of freedom. Simultaneously, we observe that non-hadronic interactions are mandatory in order to describe the narrowing of the J/Psi rapidity distribution from p+p to central Au+Au collisions at the top RHIC energy. We demonstrate additionally that the strong quenching of high-pT J/Psi's in central Au+Au collisions indicates that a fraction of final J/Psi mesons is created by a coalescence mechanism close to the phase boundary.

description: Phase sensitive amplifiers (PSAs) have the potential to empower substantial advances in emerging generations of optical communication systems as well as classical and quantum on-chip signal processing. The core building block of a PSA is a nonlinear medium. While the second-order nonlinearity ($χ^{(2)}$) is stronger than the third-order nonlinearity ($χ^{(3)}$), it is used less often in semiconductors for parametric amplification owing to the challenges of effectively phase matching the interacting waves as well as two-photon absorption of the pump. In this work, we demonstrate the successful design, fabrication, and characterization of the first $χ^{(2)}$-based semiconductor PSA using an efficient phase matching approach and a pulsed pump, based on an aluminium gallium arsenide (AlGaAs) waveguide platform. Non-centrosymmetric semiconductors such as AlGaAs offer appreciable $χ^{(2)}$. Such waveguides also achieve more than one order of magnitude greater pump field confinement when compared to other materials with large $χ^{(2)}$ such as Periodically Poled Lithium Niobate (PPLN). Our AlGaAs PSA achieves an on-chip in-phase gain, a sensitivity of 0.005 photons per pulse, and approaches theoretical minimal noise figure (NF) of 0~dB. With the capability of operating on signal states with sub-single photons per pulse, our PSA could usher in a new era of on-chip quantum circuits.

description: The generalized Gerasimov-Drell-Hearn sum rule is evaluated for the contribution of single pion production on the deuteron by explicit integration up to an energy of 1.5 GeV for both coherent and incoherent production. As elementary $γ^* N\toπN$ amplitude the MAID2003 model has been used. For incoherent production final state interaction is included in the final $NN$ and $πN$ subsystems. The resulting contribution to the generalized transverse GDH sum rule is considerably smaller than the negative contribution from the disintegration channel $d(e,e')np$ which dominates the sum rule at low $Q^2$.

We take the ratio of the muon-track to shower-like events, R, as the realistic quantity that can be measured in the neutrino telescopes. We take into account several sources of uncertainties that enter the analysis. We then examine to what extent the deviation of the initial flavor composition from w_e:w_μ:w_τ=1:2:0 can be tested.

description: The long standing problem of inexplicably short spin relaxation in carbon nanotubes (CNTs) is examined. The curvature-mediated spin-orbital interaction is shown to induce fluctuating electron spin precession causing efficient relaxation in a manner analogous to the Dyakonov-Perel mechanism. Our calculation estimates longitudinal (spin-flip) and transversal (decoherence) relaxation times as short as 150 ps and 110 ps at room temperature, respectively, along with a pronounced anisotropic dependence. Interference of electrons originating from different valleys can lead to even faster dephasing. The results can help clarify the measured data, resolving discrepancies in the literature.

description: We present the dynamic propensity distribution as an explicit measure of the degree to which the dynamics in a liquid over the time scale of structural relaxation is determined by the initial configuration. We then examine, for a binary mixture of soft discs in two dimensions, the correlation between the spatial distribution of propensity and that of two localmeasures of configuration structure: the local composition and local free volume. While the small particles dominate the high propensity population,we find no strong correlation between either the local composition or the local free volume and the propensity. It is argued that this is a generic failure of purely local structural measures to capture the inherently non-local character of collective behaviour.

Two aspects of C-4 plants : 1. effects of light intensity on photosynthesis : 2. A nitrogen-fixing association
Creators: name: Hart, Alan Leedham
Publisher: name: University of British Columbia
Year: 2010

description: Part 1 concerns the effect of light intensity on the leaves of Gomphrena globosa, a C-4 plant. Plants were grown under three light intensities. The structure and function of the photosynthetic apparatus of newly matured leaves were examined by a number of techniques. These were electron microscopy, infra-red fluorescence photomicrography, dye (TNBT) reduction and ¹⁴CO₂ feedings. Contrary to conclusions from the literature, light intensity did not affect the membrane configuration of the chioroplasts. Metabolite levels seemed to vary with light intensity. With respect to its photosynthetic properties G. globosa seems to occupy an intermediate position in a range of other C-4 plants. Part 2 describes some aspects of the relationship between a grass, Paspalum notatum, and a bacterium, Asotobacter paspali which is found mainly on the root surface of the grass. These organisms form a nitrogen fixing association in South-Eastern and Central Brazil. Both were studied separately because of the difficulty of establishing the association in the laboratory. An apparatus was built in which photosynthesis and root function of P. notatum could be monitored. ¹⁴CO₂ was fed to the leaves and ¹⁴C appearing in the roots and root exudate was analyzed. P. notatum appears to exude sufficient substrate to support nitrogen fixation by A. paspali but the amount and nature of exudate proved difficult to ascertain. The association is found in acid soils but nitrogen fixation by A. paspali is inhibited by low pH. It was found that roots of P. notatum were able to neutralize increases in acidity in their environment. A low pH inhibited N₂[C₂H₂]-fixing activity of A. paspali grown in continuous culture at high and low concentrations of carbohydrate and oxygen. Other nitrogen fixing bacteria, e.g. Beijerinckia spp and Derxia gummosa, are found in relatively low numbers in the rhizosphere of P. notatum. Nitrogen fixation by A. paspali may be less prone to oxygen inhibition than it is in these other bacteria, thus allowing A. paspali to compete more efficiently for carbohydrate. It seems that A. paspali lives with P. notatum because of the favourable pH that is maintained in the root environment. The carbohydrate and oxygen concentration are probably also favourable for nitrogen fixation. How can the association be easily established in the laboratory? Before further research can be done, a way must be found to answer this question.

description: Sulfate transporters (SULTRs) are responsible for the absorption and transport of sulfate in higher plants. They also play a key role in plant growth, development and abiotic stress responses. However, the SULTR gene family in common bean (Phaseolus vulgaris L.) is still not well studied. In this study, 15 PvSULTRs were identified. Phylogenetic analysis divided the PvSULTR genes into four subgroups. Cis-regulatory element analysis of the promoter sequence of the PvSULTR genes showed that many cis-regulatory elements were related to hormone and environmental stresses. Collinearity analysis showed that two PvSULTR gene pairs are duplicated in common bean. Tissue-specific expression analysis of the 15 PvSULTR genes showed different expression patterns in various tissues. Furthermore, real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) analysis showed that PvSULTR1/2/7 genes displayed specific responses to CdCl2 and HgCl2 stresses, whereas PvSULTR11/12 were explicitly induced by NaCl and HgCl2 stresses. These results suggest that PvSULTR family members might function under different mechanisms in response to specific metal stress. This study provides the basis for elucidating the functional diversity of PvSULTR gene family and reveals its role in metal stress response in common bean.

description: We report the observation of the baryonic B-decay B0bar -> Lambda_c^+ antiproton K^- pi^+, excluding contributions from the decay B0bar -> Lambda_c^+ anti-Lambda K^-. Using a data sample of 467*10^6 BBbar pairs collected with the BABAR detector at the PEP-II storage ring at SLAC, the measured branching fraction is (4.33 +/- 0.82_stat +/- 0.33_syst +/- 1.13_Lambda_c^+)*10^-5. In addition we find evidence for the resonant decay B0bar -> Sigma_c(2455)^++ antiproton K^- and determine its branching fraction to be (1.11 +/- 0.30_stat +/- 0.09_syst +/- 0.29_Lambda_c^+)*10^-5. The errors are statistical, systematic, and due to the uncertainty in the Lambda_c^+ branching fraction. For the resonant decay B0bar -> Lambda_c^+ antiproton K^*0 we obtain an upper limit of 2.42*10^-5 at 90% confidence level.

description: We report on the triggered generation of indistinguishable photons by solid-state single-photon sources in two separate cryogenic laser scanning microscopes. Organic fluorescent molecules were used as emitters and investigated by means of high resolution laser spectroscopy. Continuous-wave photon correlation measurements on individual molecules proved the isolation of single quantum systems. By using frequency selective pulsed excitation of the molecule and efficient spectral filtering of its emission, we produced triggered Fourier-limited single photons. In a further step, local electric fields were applied to match the emission wavelengths of two different molecules via Stark effect. Identical single photons are indispensible for the realization of various quantum information processing schemes proposed. The solid-state approach presented here prepares the way towards the integration of multiple bright sources of single photons on a single chip.

description: We calculate the conductance through strongly correlated T-shaped molecular or quantum dot systems under the influence of phonons. The system is modelled by the extended Anderson-Holstein Hamiltonian. The finite-U mean-field slave boson approach is used to study many-body effects. Phonons influence both interference and correlations. Depending on the dot unperturbed energy and the strength of electron-phonon interaction the system is occupied by a different number of electrons which effectively interact with each other repulsively or attractively. This leads together with the interference effects to different spin or charge Fano-Kondo effects

description: Zn(CN)2 is known to have an isotropic negative thermal expansion (NTE) coefficient (about -51 x 10-6 K-1) over 10-370 K that is twice as large as that of ZrW2O8. We have measured the pressure dependence of the phonon spectra up to 30 meV from a polycrystalline sample of Zn(CN)2 at pressures of 0, 0.3, 1.9 and 2.8 kbar at temperatures of 165 and 225 K. The measurements enabled us to estimate the energy dependence of the ratios Gamma/B (Gamma are Gruneisen parameters as a function of phonon energy Ei at ambient pressure and B is the bulk modulus), which reflect the anharmonicity of phonons. We conclude that the phonon modes of low energy below 15 meV play an important role in the understanding of the NTE behavior in Zn(CN)2 and the measured anharmonicity can quantitatively explain the NTE.

Towards computer-based analysis of clinical electroencephalograms
Creators: name: Doyle, Daniel John
Publisher: name: University of British Columbia
Year: 2010

description: Two approaches to the automatic analysis of clinical electroencephalograms (EEGs) are considered with a view towards classifying clin ical EEGs as normal or abnormal. The first approach examines the variability of various EEG features in a population of astronaut candidates known to be free of neurological disorders by constructing histograms of these features; unclassified EEGs of subjects in the same age group are examined by comparison of their feature values to the histograms of this neurologically normal group. The second approach employs the techniques of automatic pattern recognition for classification of clinical EEGs. A set of 57 EEG records designated normal or abnormal by clinical electro-encephalographers are used to evaluate pattern recognition systems based on stepwise discriminant analysis. In particular, the efficacy of using various feature sets in such pattern recognition systems is evaluated in terms of estimated classification error probabilities (Pe). The results of the study suggest a potential for the development of satisfactory automatic systems for the classification of clinical EEGs.

description: The atmosphere of Venus remains mysterious, with many outstanding chemical connundra. These include: the unexpected presence of ~10 ppm O2 in the cloud layers; an unknown composition of large particles in the lower cloud layers; and hard to explain measured vertical abundance profiles of SO2 and H2O. We propose a new hypothesis for the chemistry in the clouds that largely addresses all of the above anomalies. We include ammonia (NH3), a key component that has been tentatively detected both by the Venera 8 and Pioneer Venus probes. NH3 dissolves in some of the sulfuric acid cloud droplets, effectively neutralizing the acid and trapping dissolved SO2 as ammonium sulfite salts. This trapping of SO2 in the clouds together with the release of SO2 below the clouds as the droplets settle out to higher temperatures, explains the vertical SO2 abundance anomaly. A consequence of the presence of NH3 is that some Venus cloud droplets must be semi-solid ammonium salt slurries, with a pH~1, which matches Earth acidophile environments, rather than concentrated sulfuric acid. The source of NH3 is unknown, but could involve biological production; if so, then the most energy-efficient NH3-producing reaction also creates O2, explaining the detection of O2 in the cloud layers. Our model therefore predicts that the clouds are more habitable than previously thought, and may be inhabited. Unlike prior atmospheric models, ours does not require forced chemical constraints to match the data. Our hypothesis, guided by existing observations, can be tested by new Venus in situ measurements.

description: Axion electrodynamics in condensed matter could emerge from the formation of charge density waves (CDWs) in Weyl semimetals. (TaSe$_4$)$_2$I was proposed to be the first material platform for realizing axionic CDW that may host topological defects with one-dimensional in-gap modes. The real-space modulation of the CDW phase and the existence of in-gap modes remain elusive. Here, we present a comprehensive scanning tunneling microscopic and spectroscopic study of a CDW on a (TaSe$_4$)$_2$I (110) surface. The tunneling spectroscopic measurements reveal a CDW gap of $\sim 200$ meV, in good agreement with prior studies, while the spectroscopy of CDW edge dislocation shows no indication of in-gap states. The bias-dependent scanning tunneling microscopy images indicate that the CDW in(TaSe$_4$)$_2$I is dominated by a large periodic lattice distortion instead of charge modulation, suggesting a non-Peierls mechanism of the CDW instability.

description: Sufficient dimension reduction methods often require stringent conditions on the joint distribution of the predictor, or, when such conditions are not satisfied, rely on marginal transformation or reweighting to fulfill them approximately. For example, a typical dimension reduction method would require the predictor to have elliptical or even multivariate normal distribution. In this paper, we reformulate the commonly used dimension reduction methods, via the notion of "central solution space," so as to circumvent the requirements of such strong assumptions, while at the same time preserve the desirable properties of the classical methods, such as $\sqrt{n}$-consistency and asymptotic normality. Imposing elliptical distributions or even stronger assumptions on predictors is often considered as the necessary tradeoff for overcoming the "curse of dimensionality," but the development of this paper shows that this need not be the case. The new methods will be compared with existing methods by simulation and applied to a data set.

description: The performance of HITRAN 2020 and 2016 databases on calculating radiative heat transfer of H2O and CO2 was evaluated in this study. The main spectral bands and lines contributing to the discrepancy in accuracy between the HITRAN 2020 and 2016 databases were determined. For the calculation of radiation of H2O, the HITRAN 2020 database showed higher accuracy than the HITRAN 2016 database in the isothermal/homogeneous cases. The maximum relative error of radiative heat flux of the HITRAN 2020 was reduced by 3.93%, due to the addition of 157, 165, 110 and 121 spectral lines in the 3425–3450 cm−1, 3600–3625 cm−1, 3950–3975 cm−1 and 4050–4075 cm−1 wavebands, respectively. Whereas, for the isothermal/homogeneous CO2, the difference of the average relative error in radiative source calculated by the HITRAN 2020 and 2016 databases was less than 0.1%. For the air and oxy-fuel combustion cases, the HITRAN 2020 showed a better performance than the HITRAN 2016 on predicting radiative heat transfer. The maximum relative error of radiative heat flux of the HITRAN 2020 was reduced by 4.32%. This was mainly ascribed to the increase in the number of the spectral lines of H2O in the HITRAN 2020 in the wavebands of 3425–3450 cm−1, 3600–3625 cm−1, 3950–3975 cm−1 and 4050–4075 cm−1 at high temperatures.

description: We examine current numerical relativity computations of gravitational waves, which typically determine the asymptotic waves at infinity by extrapolation from finite (small) radii. Using simulations of a black hole binary with accurate wave extraction at $r=1000M$, we show that extrapolations from the near-zone are self-consistent in approximating measurements at this radius, although with a somewhat reduced accuracy. We verify that $ψ_4$ is the dominant asymptotic contribution to the gravitational energy (as required by the peeling theorem) but point out that gauge effects may complicate the interpretation of the other Weyl components.

description: For EEG-based drowsiness recognition, it is desirable to use subject-independent recognition since conducting calibration on each subject is time-consuming. In this paper, we propose a novel Convolutional Neural Network (CNN)-Long Short-Term Memory (LSTM) model for subject-independent drowsiness recognition from single-channel EEG signals. Different from existing deep learning models that are mostly treated as black-box classifiers, the proposed model can explain its decisions for each input sample by revealing which parts of the sample contain important features identified by the model for classification. This is achieved by a visualization technique by taking advantage of the hidden states output by the LSTM layer. Results show that the model achieves an average accuracy of 72.97% on 11 subjects for leave-one-out subject-independent drowsiness recognition on a public dataset, which is higher than the conventional baseline methods of 55.42%-69.27%, and state-of-the-art deep learning methods. Visualization results show that the model has discovered meaningful patterns of EEG signals related to different mental states across different subjects.

description: According to Pixton, there are Morse-Smale diffeomorphisms of the 3-sphere which have no energy function, that is a Lyapunov function whose critical points are all periodic points of the diffeomorphism. We introduce the concept of quasi-energy function for a Morse-Smale diffeomorphism as a Lyapunov function with the least number of critical points and construct a quasi-energy function for any diffeomorphism from some class of Morse-Smale diffeomorphisms on the 3-sphere.

description: In the last two decades and beyond is robustly developed a line of investigation and critical-literary-musical theater around the opera librettos. A field that is growing and going through specialized education or more minute explorations, including pedagogical and educational reflection. Even today we discuss a lot about the identity of opera librettos, and the author has touched on some innovative aspects that emerged during the Romanticism, such as, for example, civil, political and ideological issues (themes still very present). He deals with major authors, such as Giuseppe Verdi, stressing the educational, political and cultural value of their works and textbooks on.

description: This work is motivated by the pervasive use of method invocations in object-oriented (OO) programs, and indeed their prevalence in patches of OO-program bugs. We propose a generate-and-validate repair technique, called ELIXIR designed to be able to generate such patches. ELIXIR aggressively uses method calls, on par with local variables, fields, or constants, to construct more expressive repair-expressions, that go into synthesizing patches. The ensuing enlargement of the repair space, on account of the wider use of method calls, is effectively tackled by using a machine-learnt model to rank concrete repairs. The machine-learnt model relies on four features derived from the program context, i.e., the code surrounding the potential repair location, and the bug report. We implement ELIXIR and evaluate it on two datasets, the popular Defects4J dataset and a new dataset Bugs.jar created by us, and against 2 baseline versions of our technique, and 5 other techniques representing the state of the art in program repair. Our evaluation shows that ELIXIR is able to increase the number of correctly repaired bugs in Defects4J by 85% (from 14 to 26) and by 57% in Bugs.jar (from 14 to 22), while also significantly out-performing other state-of-the-art repair techniques including ACS, HD-Repair, NOPOL, PAR, and jGenProg.

description: Fish scale hydroxyapatite (FS-HAP) has been used as an efficient catalyst for the synthesis of 3-amino-1H-pyrazolo[1,2-b]phthalazine-2-carboxamide derivatives via the one-pot, three-component cyclocondensation reactions of aromatic aldehydes with cyanoacetamide and phthalhydrazide under solvent-free condition. FS-HAP has been characterized by FT-IR, XRD, SEM and EDS techniques. The synthesized compounds were evaluated for their in vitro antibacterial activity against gram-positive (Bacillus cereus, Bacillus aryabhattai, Bacillus megaterium, Staphylococcus aureus) and gram-negative (Serratia marcescens, Bacillus Pseudomonas putida, Escherichia coli, Enterobacter cloacae) bacteria. Tetracycline and erythromycin were used as standard antibiotics in this investigation. In the present protocol, we have achieved remarkable yields of the product in shorter reaction time and the catalyst was easily recovered and reused.

description: We have found the exact (factorized) ground state of a general class of ferrimagnets in the presence of a magnetic field which covers the frustrated, anisotropic and long range interactions for arbitrary dimensional space. In particular cases, our model represents the bond-alternating, ferromagnet-antiferromagnet and also homogeneous spin $s$ model. The factorized ground state is a product of single particle kets on a bipartite lattice composed of two different spins ($ρ, σ$). The spin waves analysis around the exact ground state show two branch of excitations which is the origin of two dynamics of the model. The signature of these dynamics is addressed as a peak and a broaden bump in the specific heat.

Direct Photon-Hadron Correlations Measured with PHENIX
Creators: name: Connors, Megan
Publisher: name: arXiv
Year: 2009
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Direct photon-hadron correlations greatly improve our ability to perform jet tomography in heavy-ion collisions because the momentum of the direct photon can be used to constrain the initial momentum of the opposing jet. By comparing the spectrum of away-side hadrons observed in heavy ion collisions to the spectrum seen in nucleon collisions we can quantify the medium modification to the fragmentation function due to energy loss of the away-side parton. High $p_{T}$ direct photon-hadron correlations have been measured with the PHENIX detector using a statistical subtraction method to remove the photon contribution from meson decays. The increased integrated luminosity in the most recent Au+Au RHIC run at $\sqrt{s_{NN}}$ = 200 GeV provides substantially improved statistical precision and enhances the kinematic reach. These measurements are compared to PHENIX p+p results and several theoretical models of energy loss. In addition, we compare direct photon-hadron and $π^{0}$-hadron correlations.
