description: Code search is an important and frequent activity for developers using computational notebooks (e.g., Jupyter). The flexibility of notebooks brings challenges for effective code search, where classic search interfaces for traditional software code may be limited. In this paper, we propose, NBSearch, a novel system that supports semantic code search in notebook collections and interactive visual exploration of search results. NBSearch leverages advanced machine learning models to enable natural language search queries and intuitive visualizations to present complicated intra- and inter-notebook relationships in the returned results. We developed NBSearch through an iterative participatory design process with two experts from a large software company. We evaluated the models with a series of experiments and the whole system with a controlled user study. The results indicate the feasibility of our analytical pipeline and the effectiveness of NBSearch to support code search in large notebook collections.

Effects of early dark energy on strong cluster lensing

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use the semi-analytic method developed by Fedeli et al. for computing strong-lensing optical depths to study the statistics of gravitational arcs in four dark-energy cosmologies. Specifically, we focus on models with early dark energy and compare them to more conventional models. Merger trees are constructed for the cluster population because strong cluster lensing is amplified by factors of two to three during mergers. We find that the optical depth for gravitational arcs in the early dark-energy models is increased by up to a factor of about 3 compared to the other models because of the modified dynamics of cluster formation. In particular, the probability for gravitational arcs in high-redshift clusters is considerably increased, which may offer an explanation for the unexpectedly high lensing efficiency of distant clusters.

description: An improved description for nonlinear plasma wakefields with phase velocities near the speed of light is presented and compared against fully kinetic particle-in-cell simulations. These wakefields are excited by intense particle beams or lasers pushing plasma electrons radially outward, creating an ion bubble surrounded by a sheath of electrons characterized by the source term $S \equiv -\frac{1}{en_p}(ρ-J_z/c)$ where $ρ$ and $J_z$ are the charge and axial current densities. Previously, the sheath source term was described phenomenologically with a positive-definite function, resulting in a positive definite wake potential. In reality, the wake potential is negative at the rear of the ion column which is important for self-injection and accurate beam loading models. To account for this, we introduce a multi-sheath model in which the source term, $S$, of the plasma wake can be negative in regions outside the ion bubble. Using this model, we obtain a new expression for the wake potential and a modified differential equation for the bubble radius. Numerical results obtained from these equations are validated against particle-in-cell simulations for unloaded and loaded wakes. The new model provides accurate predictions of the shape and duration of trailing bunch current profiles that flatten plasma wakefields. It is also used to design a trailing bunch for a desired longitudinally varying loaded wakefield. We present beam loading results for laser wakefields and discuss how the model can be improved for laser drivers in future work. Finally, we discuss differences between the predictions of the multi- and single-sheath models for beam loading.

description: Graphene is a two-dimensional carbon material with a honeycomb lattice and Dirac-like low-energy excitations. When Zeeman and spin-orbit interactions are neglected its Landau levels are four-fold degenerate, explaining the $4 e^2/h$ separation between quantized Hall conductivity values seen in recent experiments. In this paper we derive a criterion for the occurrence of interaction-driven quantum Hall effects near intermediate integer values of $e^2/h$ due to charge gaps in broken symmetry states.

Fourier method in the determination of rotational velocities in OB stars

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We present a comprehensive study that applies the Fourier transform to a sample of O and early B-type stars (either dwarfs, giants, or supergiants) to determine their projected rotational velocities, compare with previous values obtained with other methods, and seek for evidence of extra broadening in the spectral lines The Fourier technique, extensively used in the study of cooler stars, has remained only marginally applied for the case of early-type stars. The comparison of \vsini values obtained through the \ft and \fwhm methods shows that the \fwhm technique must be used with care in the analysis of OB giants and supergiants, and when it is applied to \ion{He}{i} lines. Contrarily, the \ft method appears to be a powerful tool to derive reliable projected rotational velocities, and separate the effect of rotation from other broadening mechanisms present in these stars. The analysis of the sample of OB stars shows that while dwarfs and giants display a broad range of projected rotational velocities, from less than 30 up to 450 \kms, supergiants have in general values close to or below 100 \kms. The analysis has also definitely shown that while the effect of extra broadening is negligible in OB dwarfs, it is clearly present in supergiants. When examining the behavior of the projected rotational velocities with the stellar parameters and across the HR diagram, we conclude, in agreement with previous researchers, that the rotational velocity should decrease when the stars evolve. On the contrary, macroturbulence may be constant, resulting therefore in an increasing importance as compared to rotation when the stars evolve.

Syntheses, vibrational and solution studies of niobium(V) and tantalum(V) fluoride fluorosulfates
Creators: name: Zhang, Dingliang
Publisher: name: University of British Columbia
Year: 2010

description: A one-step metal oxidation/ligand redistribution reaction was developed to synthesize niobium(V) and tantalum(V) fluoride fluorosulfates according to the equation: (5-n)M + nMF₅ + excess S₂0₆F₂ ⇢ 5MF[formula omitted](S0₃F)₅-[formula omitted] Five compounds, Nb₂F₉(S0₃F), NbF₄(S0₃F), NbF₃(S0₃F)₂, TaF₄(S0₃F), and TaF₃(S0₃F)₂, were isolated as colorless viscous liquids in pure form. Nb₂F₉(S0₃F) appears to be unstable, and disproportionates into solid [NbF₅]₄ and liquid NbF₄(S0₃F) on long standing. Ta₂F₉(S0₃F) cannot be synthesized in this manner. The attempted isolation of compounds with higher fluorosulfate content, MF[formula omitted](S0₃F)₅-[formula omitted] (M=Nb, Ta; n<3), was not successful. Raman and infrared spectra of the isolated compounds, MF[formula omitted](S0₃F)₅-[formula omitted] (M=Nb, Ta; n≥3), are interpreted in terms of associated structures with approximately octahedral coordination of niobium or tantalum by fluorides and fluorosulfate groups. Bidentate fluorosulfate groups, presumably bridging, are found in all these derivatives. In NbF₃(S0₃F)₂ and TaF₃(S0₃F)₂ both monodentate and bidentate fluorosulfate groups are found. Bridging fluorines are suggested for liquid Nb₂F₉(S0₉F) and, to a lesser extent, NbF₄(S0₃F) and TaF₄(S0₃F) as well. Tentative assignments of the vibrational bands are discussed. The behavior of the stable compounds, MFn(S0₃F)₅-[formula omitted] (M=Nb, Ta; n=2, 3), in HS0₃F was investigated by conductometric studies. At low Lewis acid concentrations, the results show that TaF₃(S0₃F)₂ is a weak Lewis acid in HS0₃F and that NbF₃(S0₃F)₂, NbF₄(S0₃F) and TaF₄(S0₃F) behave as very weak electrolytes and poor S0₃Fˉ acceptors. Conductivities of these solutions in HS0₃F follow the order: TaF₃(S0₃F)₂ » NbF₃(S0₃F)₂ > TaF₄(S0₃F) > NbF₄(S0₃F) . The general trend previously reported for HS0₃F/SbF₅/S0₃ and HS0₃F/AsF₅/S0₃ systems is valid for HS0₃F/NbF[formula omitted](S0₃F)₅-[formula omitted] and HS0₃F/TaF[formula omitted](S0₃F)₅-[fomula omitted] systems, i.e., the more fluorines replaced by fluorosulfate groups, the stronger the resulting superacid. At high Lewis acid concentrations, viscous and highly conducting liquids are present. For the conductivities of the neat liquids, the following order was observed: NbF₃(S0₃F)₂ > TaF₃(S0₃F)₂ > NbF₄(S0₃F) > TaF₄(S0₃F).

description: Double perovskite iridates $A_2$ZnIrO$_6$ ($A$ = alkaline or lanthanide) show complex magnetic behaviors ranging from weak ferromagnetism to successive antiferromagnetic transitions. Here we report the static ($dc$) and dynamic ($ac$) magnetic susceptibility, and neutron powder diffraction measurements for $A$ = La and Nd compounds to elucidate the magnetic ground state. Below 10~K, the $A$ = La compound is best described as canted iridium moments in an antiferromagnet arrangement with a propagation vector \textbf{k} = 0 and a net ferromagnetic component along the $c$-axis. On the other hand, Nd$_2$ZnIrO$_6$ is described well as an antiferromagnet with a propagation vector \textbf{k} = (1/2~1/2~0) below $T_\mathrm{N} \sim$ 17 K. Scattering from both the Nd and Ir magnetic sublattices were required to describe the data and both were found to lie almost completely within the $ab$-plane. $Dc$ susceptibility revealed a bifurcation between the zero-field-cooled and field-cooled curves below $\sim$13 K in Nd$_2$ZnIrO$_6$. A glassy state was ruled out by $ac$ susceptibility but detailed magnetic isotherms revealed the opening of the loop below 13~K. These results suggest a delicate balance exists between the Dzyaloshinskii-Moriya, crystal field schemes, and $d$-$f$ interaction in this series of compounds.

We extend the notion of asymptotic iteration method to solve the 2 \times 2 matrix Hamiltonians. On a particular case, eigenvalues of the Rabi and Rashba Hamiltonians are computed. The method presented here reproduces a number of earlier results in a natural way as well as leads to a novel findings. Possible generalizations of the method are also suggested.

description: We show that the conductance $G$ of molecular tunnel junctions wherein the charge transport is dominated by a single energy level can be expressed in closed analytic form which is exact and valid at arbitrary temperature $T$ and model parameter values. On this basis, we show that the single-step tunneling mechanism is compatible with a continuous thermal transition from a weakly $T$-dependent $G$ at low $T$ (Sommerfeld regime) to a nearly exponential $1/T$-dependent $G$ at high $T$ (Arrhenius-like regime). We predict that this Sommerfeld-Arrhenius transition can be observed in real molecular junctions % (e.g., based on perylene diimide) and can be continuously tuned, e.g., via mechanical stretching.

description: We study higher order corrections to extremal black holes/black string in five dimensions. These higher order corrections are due to supersymmetric completion of R**2 term in five dimensions. By making use of the results we extend the notion of very special geometry when higher derivative terms are also taken into account. This can be used to make a connection between total bundle space of near horizon wrapped M2's and wrapped M5's in the presence of higher order corrections. We also show how the corrected geometry removes the singularity of a small black hole.

Glass transition in fullerenes: mode-coupling theory predictions

name: Voigtmann, Th.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We report idealized mode-coupling theory results for the glass transition of ensembles of model fullerenes interacting via phenomenological two-body potentials. Transition lines are found for C60, C70 and C96 in the temperature-density plane. We argue that the observed glass-transition behavior is indicative of kinetic arrest that is strongly driven by the inter-particle attraction in addition to excluded-volume repulsion. In this respect, these systems differ from most standard glass-forming liquids. They feature arrest that occurs at lower densities and that is stronger than would be expected for repulsion-dominated hard-sphere-like or Lennard-Jones-like systems. The influence of attraction increases with increasing the number of carbon atoms per molecule. However, unrealistically large fullerenes would be needed to yield behavior reminiscent of recently investigated model colloids with strong short-ranged attraction (glass-glass transitions and logarithmic decay of time-correlation functions).

description: Hyperplanes of the form x_j = x_i + c are called affinographic. For an affinographic hyperplane arrangement in R^n, such as the Shi arrangement, we study the function f(M) that counts integral points in [1,M]^n that do not lie in any hyperplane of the arrangement. We show that f(M) is a piecewise polynomial function of positive integers M, composed of terms that appear gradually as M increases. Our approach is to convert the problem to one of counting integral proper colorations of a rooted integral gain graph. An application is to interval coloring in which the interval of available colors for vertex v_i has the form [(h_i)+1,M]. A related problem takes colors modulo M; the number of proper modular colorations is a different piecewise polynomial that for large M becomes the characteristic polynomial of the arrangement (by which means Athanasiadis previously obtained that polynomial). We also study this function for all positive moduli.

C-QUEB: Canadian Questionnaire of language use and exposure in bilingual preschool-aged children
Creators: MacLeod, Andrea A.N.
Publisher: name: University of Alberta Library
Year: 2021

The C-QUEB is a questionnaire developed in our lab that aims to describe the language use and exposure of bilingual preschool-aged children.  We administer this questionnaire as a structured interview with one of the child’s caregivers.  The questionnaire asks about the child’s first language(s), the language(s) caregivers use with their child, the language(s) their child uses with them, and the age at which the child began to be exposed to each language. The age when significant exposure begins is framed as when children were regularly exposed to the language by a formative adult, thus passive exposure through TV was not sufficient. Caregiver are asked to estimate the amount of exposure their child currently received in each language on an average weekday and weekend day and to do so across the child's different contexts (e.g., home, daycare, school) and different caregivers (e.g., mother, father, babysitters, daycare workers). We standardized the duration of a day to reflect a 12-hour day.  We have developed a worksheet to guide the calculation of the duration of exposure to each language and the current language exposure.  While we capture exposure from siblings, we have not used this information in the calculation of exposure to each language by significant adults.  This questionnaire could be adapted to school-aged children by including questions about language use with peers and in community activities (e.g., sports, clubs, etc.).

description: In order to probe nanostructures on a surface we present a microscope based on the quantum recurrence phenomena. A cloud of atoms bounces off an atomic mirror connected to a cantilever and exhibits quantum recurrences. The times at which the recurrences occur depend on the initial height of the bouncing atoms above the atomic mirror, and vary following the structures on the surface under investigation. The microscope has inherent advantages over existing techniques of scanning tunneling microscope and atomic force microscope. Presently available experimental technology makes it possible to develop the device in the laboratory.

description: This paper proposes a novel linear prediction coding-based data aug-mentation method for children's low and zero resource dialect ASR. The data augmentation procedure consists of perturbing the formant peaks of the LPC spectrum during LPC analysis and reconstruction. The method is evaluated on two novel children's speech datasets with one containing California English from the Southern CaliforniaArea and the other containing a mix of Southern American English and African American English from the Atlanta, Georgia area. We test the proposed method in training both an HMM-DNN system and an end-to-end system to show model-robustness and demonstrate that the algorithm improves ASR performance, especially for zero resource dialect children's task, as compared to common data augmentation methods such as VTLP, Speed Perturbation, and SpecAugment.

Kinetic studies of the reaction of gallium arsenide with molecular chlorine and iodine

description: The GaAs/Cl₂ reaction has been studied at pressures of Cl₂ between 0.10 and 9.0 Torr, and in the temperature range from 90 to 110°C whereas the GaAs/I₂ reaction has been investigated at four temperatures between 270 and 330°C with the I₂ pressure being varied between 0.10 and 1.25 Ton. Both reactions show a linear dependence on the etchant gas pressure in the low pressure region, however, the dependence become nonlinear in the high pressure range. In the case of the Cl₂ reaction, the non linearity was found to be due to the occurrence of a reaction that was half order with respect to the pressure of Cl₂. This behavior was found to be consistent with a "reversible dissociative adsorption" mechanism proposed in earlier studies of the Cl₂ and Br₂ etching of silicon. This mechanism involves the physisorption of the halogen molecule on the semiconductor surface followed by the dissociation of the molecule into chemisorbed atoms, and finally the reaction of these atoms with the surface to yield gaseous products. The first and the half order rate constant for both reactions were determined and represented in the form of the following Arrhenius equations: ...[more text]

description: We have used the field stars from the open cluster survey BOCCE, to study three low-latitude fields imaged with the Canada-France-Hawaii telescope (CFHT), with the aim of better understanding the Galactic structure in those directions. Due to the deep and accurate photometry in these fields, they provide a powerful discriminant among Galactic structure models. In the present paper we discuss if a canonical star count model, expressed in terms of thin and thick disc radial scales, thick disc normalization and reddening distribution, can explain the observed CMDs. Disc and thick disc are described with double exponentials, the spheroid is represented with a De Vaucouleurs density law. In order to assess the fit quality of a particular set of parameters, the colour distribution and luminosity function of synthetic photometry is compared to that of target stars selected from the blue sequence of the observed colour-magnitude diagrams. Through a Kolmogorov-Smirnov test we find that the classical decomposition halo-thin/thick disc is sufficient to reproduce the observations--no additional population is strictly necessary. In terms of solutions common to all three fields, we have found a thick disc scale length that is equal to (or slightly longer than) the thin disc scale.

description: Tactoids are spindle shaped-droplets of a uniaxial nematic phase suspended in the co-existing isotropic phase. They are found in dispersions of a wide variety of elongated colloidal particles, including actin, fd virus, carbon nanotubes, vanadium peroxide and chitin nanocrystals. Recent experiments on tactoids of chitin nanocrystals in water show that electric fields can very strongly elongate tactoids even though the dielectric properties of the co-existing isotropic and nematic phases differ only subtly. We develop a model for partially bipolar tactoids, where the degree of bipolarness of the director field is free to adjust to optimize the sum of the elastic, surface and Coulomb energies of the system. By means of a combination of a scaling analysis and a numerical study, we investigate the elongation and director field's behavior of the tactoids as a function of their size, the strength of the electric field, the surface tension, anchoring strength, the elastic constants and the electric susceptibility anisotropy. We find that tactoids cannot elongate significantly due to an external electric field, unless the director field is bipolar or quasi bipolar and is somehow frozen in the field-free configuration. Presuming that this is the case, we find reasonable agreement with experimental data.

description: We report a measurement of the time-dependent CP-asymmetry parameters $\cal S$ and $\cal C$ in color-suppressed $B^0 \to D^{(*)0} h^0$ decays, where $h^0$ is a $π^0$, $η$, or $ω$ meson, and the $D^0$ decays to one of the CP eigenstates $K^+K^-$, $K_Sπ^0$, or $K_Sω$. The data sample consists of $383\times 10^{6}$ $Υ(4S)\to B\bar{B}$ decays collected with the BABAR detector at the PEP-II asymmetric-energy $B$-factory at SLAC. The results are ${\cal S}= -0.56 \pm 0.23 \pm 0.05$ and ${\cal C}= -0.23\pm 0.16\pm 0.04$, where the first error is statistical and the second is systematic.

description: Quality of Service (QoS) is now regarded as a requirement for all networks in managing resources like bandwidth and avoidance of network impairments like packet loss, jitter, and delay. Media transfer or streaming would be virtually impossible if QoS parameters were not used even if the streaming protocols were perfectly designed. QoS Scheduling classes help in network traffic optimization and the priority management of packets. This paper presents an analysis of QoS scheduling classes using video traffic in a MANET. The main objective was to identify a scheduling class that provides better QoS for video streaming. A simulation was conducted using NetSim and results were analyzed according to throughput, jitter, and delay. The overall results showed that extended real-time Polling Service (ertPS) outperformed the other classes. ertPS has hybrid features of both real-time Polling Service (rtPS) and Unsolicited Grant Service(UGS) hence the enhanced performance. It is recommended that ertPS scheduling class should be used in MANET where QoS consideration is utmost particularly in multimedia streaming applications.

description: A local equilibrium approach for the kinetics of a simplified protein folding model, whose equilibrium thermodynamics is exactly solvable, was developed in [M. Zamparo and A. Pelizzola, Phys. Rev. Lett. 97, 068106 (2006)]. Important properties of this approach are (i) the free energy decreases with time, (ii) the exact equilibrium is recovered in the infinite time limit, (iii) the equilibration rate is an upper bound of the exact one and (iv) computational complexity is polynomial in the number of variables. Moreover, (v) this method is equivalent to another approximate approach to the kinetics: the path probability method. In this paper we give detailed rigorous proofs for the above results.

Optimal Power Allocation for Distributed Detection over MIMO Channels in Wireless Sensor Networks

description: In distributed detection systems with wireless sensor networks, the communication between sensors and a fusion center is not perfect due to interference and limited transmitter power at the sensors to combat noise at the fusion center's receiver. The problem of optimizing detection performance with such imperfect communication brings a new challenge to distributed detection. In this paper, sensors are assumed to have independent but nonidentically distributed observations, and a multi-input/multi-output (MIMO) channel model is included to account for imperfect communication between the sensors and the fusion center. The J-divergence between the distributions of the detection statistic under different hypotheses is used as a performance criterion in order to provide a tractable analysis. Optimizing the performance (in terms of the J-divergence) with individual and total transmitter power constraints on the sensors is studied, and the corresponding power allocation scheme is provided. It is interesting to see that the proposed power allocation is a tradeoff between two factors, the communication channel quality and the local decision quality. For the case with orthogonal channels under certain conditions, the power allocation can be solved by a weighted water-filling algorithm. Simulations show that, to achieve the same performance, the proposed power allocation in certain cases only consumes as little as 25 percent of the total power used by an equal power allocation scheme.

The manual inspection of machine tool components and the manual end-of-line check of products are labor-intensive tasks in industrial applications that companies often want to automate. To automate classification processes and develop reliable and robust machine learning-based classification and wear prognostics models, one needs real-world datasets to train and test the models.

description: Highly supercritical strings (c much greater than 15) with a time-like linear dilaton provide a large class of solutions to string theory, in which closed string tachyon condensation is under control (and follows the worldsheet renormalization group flow). In this note we analyze the late-time stability of such backgrounds, including transitions between them. The large friction introduced by the rolling dilaton and the rapid decrease of the string coupling suppress the back-reaction of naive instabilities. In particular, although the graviton, dilaton, and other light fields have negative effective mass squared in the linear dilaton background, the decaying string coupling ensures that their condensation does not cause large back-reaction. Similarly, the copious particles produced in transitions between highly supercritical theories do not back-react significantly on the solution. We discuss these features also in a somewhat more general class of time-dependent backgrounds with stable late-time asymptotics.

description: Objective To investigate the association between expression level of VHL in pathological tissue and outcomes of platinum-based chemotherapy in non-small cell lung cancer (NSCLC) patients. Methods The pathological samples of NSCLC patients were obtained for immunohistochemical staining to evaluate the expression level of VHL. Furthermore, their clinical data were collected and prognosis was traced by phone. The correlation between gene expression level and the hematotoxicity was evaluated by chi-square test. The influence of VHL expression level on the risk of hematotoxicity was tested by logistic regression model. The survival curve was plotted by Kaplan-Meier method and the survival rate between the two groups was compared by log-rank test. Results A total of 110 NSCLC patients were enrolled in this study, the median follow-up time of these patients was 27.5 months. In the whole group, 31 patients had died by the last date of follow-up to get their survival information (Nov.10,2020), with a median survival time of 24.3 months. Though immunohistochemical analysis,we found that 59 patients(53.6%) had weak expression level of VHL or lack of expression in their tumor tissues,while 51 patients(46.4%) presented moderate or high expression. We found that the patients with weak expression of VHL in their carcinoma tissue or lack of expression had more opportunities to occur neutropenia after platinum-based chemotherapy(OR=0.264,95%CI=0.085-0.818,P-value=0.021).And the expression level of VHL was correlated with OS(Logrank test：P-value= 0.007，HR= 4.219,95%CI: 1.75-10.174, P-value=0.001), while not related with DFS(Logrank test：P-value=0.256，HR= 1.334,95%CI:0.642-2.769, P-value=0.440). Conclusion The expression level of VHL gene in pathological tissue is related with Granulocytosis and leukocytotoxicity after platinum-based chemotherapy in NSCLC patients. It can be used as a biomarker to predict the risk of neutropenia and the prognosis of NSCLC patients.

description: The dynamics of the 4-body problem allows for two binary collisions to occur simultaneously. It is known that in the collinear 4-body problem this simultaneous binary collision (SBC) can be block-regularised, but that the resulting block map is only $C^{8/3}$ differentiable. In this paper, it is proved that the $C^{8/3}$ differentiability persists for the SBC in the planar 4-body problem. The proof uses several geometric tools, namely, blow-up, normal forms, dynamics near normally hyperbolic manifolds of equilibrium points, and Dulac maps.
