description: Enhanced transmissions through a gold film with arrays of subwavelength holes are theoretically studied, employing the rigid full vectorial three dimensional finite difference time domain method. Influence of air-holes shape to the transmission is firstly studied, which confirms two different resonances attributing to the enhanced transmission: the localized waveguide resonance and periodic surface plasmon resonances. For the film coated with dielectric layers, calculated results show that in the wavelength region of interest the localized waveguide resonant mode attributes to sensing rather than the periodic gold-glass surface plasmon mode. Although the detected peak is fairly broad and the shift is not too pronounced, we emphasize the contribution for sensing from the localized waveguide resonant mode, which may opens up new ways to design surface plasmon based sensors.

description: We present UVES/VLT observations of the nearby flare star CN Leo covering the Wing-Ford FeH band near 1mu with high spectral resolution. Some of the FeH absorption lines in this band are magnetically sensitive and allow a measurement of the mean magnetic flux on CN Leo. Our observations, covering three nights separated by 48 hours each, allow a clear detection of a mean magnetic field of Bf~2.2kG. The differential flux measurements show a night-to-night variability with extremely high significance. Finally, our data strongly suggest magnetic flux variability on time scales as low as 6 hours in line with chromospheric variability.

The Energy Cascade from Warm Dark Matter Decays

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use a set of Monte Carlo simulations to follow the cascade produced by a primary electron of energy E_in in the intergalactic medium. We choose E_in=3-10 keV as expected from the decay of one of the most popular Warm Dark Matter (WDM) candidates, sterile neutrinos. Our simulation takes into account processes previously neglected such as free-free interactions with ions and recombinations and uses the best available cross sections for collisional ionizations and excitations with H and He and for electron-electron collisions. We precisely derive the fraction of the primary electron energy that heats the gas, ionizes atoms and produces line and continuum photons as a function of the ionization fraction. Handy fitting formulae for all the above energy depositions are provided. By keeping track of the individual photons we can distinguish between photons in the Ly-alpha resonance and those with energy E < 10.2 eV that do not interact further with gas. This separation is important because a Ly-alpha background can heat or cool the gas depending on the nature of the photons, and can have effects on the 21 cm radiation emitted by neutral H, which will probably become detectable at z > 6 in the near future by the next generation radio interferometers.

$L\sp p$-$L\sp q$ regularity of Fourier integral operators with caustics

Publisher: name: arXiv

Subjects: subject: Analysis of PDEs (math.AP)

description: The caustics of Fourier integral operators are defined as caustics of the corresponding Schwartz kernels (Lagrangian distributions on $X\times Y$). The caustic set $Σ(C)$ of the canonical relation $C$ is characterized as the set of points where the rank of the projection $π:C\to X\times Y$ is smaller than its maximal value, $dim(X\times Y)-1$. We derive the $L\sp p(Y)\to L\sp q(X)$ estimates on Fourier integral operators with caustics of corank 1 (such as caustics of type $A\sb{m+1}$, $m\in\N$). For the values of $p$ and $q$ outside of certain neighborhood of the line of duality, $q=p'$, the $L\sp p\to L\sp q$ estimates are proved to be caustics-insensitive. We apply our results to the analysis of the blow-up of the estimates on the half-wave operator just before the geodesic flow forms caustics.

description: We measure the Ly$α$ escape fraction of 935 [OIII]-emitting galaxies between $1.9 < z < 2.35$ by comparing stacked spectra from the Hubble Space Telescope/WFC3's near-IR grism to corresponding stacks from the Hobby Eberly Telescope Dark Energy Experiment's Internal Data Release 2. By measuring the stacks' H$β$ to Ly$α$ ratios, we determine the Ly$α$ escape fraction as a function of stellar mass, star formation rate, internal reddening, size, and [OIII]/H$β$ ratio. We show that the escape fraction of Ly$α$ correlates with a number of parameters, such as galaxy size, star formation rate, and nebular excitation. However, we also demonstrate that most of these relations are indirect, and the primary variables that control the escape of Ly$α$ are likely stellar mass and internal extinction. Overall, the escape of Ly$α$ declines from $\gtrsim 18\%$ in galaxies with $\log M/M_{\odot} \lesssim 9$ to $\lesssim 1\%$ for systems with $\log M/M_{\odot} \gtrsim 10$, with the sample's mean escape fraction being $6.0^{+0.6\%}_{-0.5\%}$.

Critical Point of an Interacting Two-Dimensional Atomic Bose Gas

description: We have measured the critical atom number in an array of harmonically trapped two-dimensional (2D) Bose gases of rubidium atoms at different temperatures. We found this number to be about five times higher than predicted by the semi-classical theory of Bose-Einstein condensation (BEC) in the ideal gas. This demonstrates that the conventional BEC picture is inapplicable in an interacting 2D atomic gas, in sharp contrast to the three-dimensional case. A simple heuristic model based on the Berezinskii-Kosterlitz-Thouless theory of 2D superfluidity and the local density approximation accounts well for our experimental results.

3D reconstruction

description: This deliverable will report on the set of tools for 3D modelling of the human anatomy and 3D registration from intra-operative (i.e. endoscopic images) and pre-operative data (e.g. MRI scans). The 3D reconstruction of the anatomy will be carried out by exploiting the most advanced 3D vision techniques, including stereo and multi-view geometry, Simultaneous Location and Mapping (SLAM)
 and non-rigid structure-from-motion. In this document we will present all the work that has been performed during the SARAS project to allow the system to automatically generate a 3D map of the anatomical environment. With respect to standard 3D reconstruction applications, our scenario presents specific challenges that make the problem extreme. First of all the structures (i.e. organs) we are interested in reconstruct are highly
 deformable, with no reliable dynamical models available in advance. Furthermore, the anatomical structures are connected to each other by means of fat, vessels and connective tissues with high variability in mechanical properties, which makes the behaviour of these connections unpredictable. Lastly, the variability of shape, dimensions and appearance of these structures is extremely high, so to make impossible to use a prototype model to be used for the majority of the subjects as prior
 knowledge.
 In the rest of this document we will provide details and discussions about all the main phases involved in this task, including system calibration, multiple view geometrical reconstruction and integration with the robot kinematics.
 In Section 2 we present all the technical aspects related to the calibration of the vision system, both in terms of camera calibration and camera-robot calibration to make the results of 3D reconstruction of the anatomical environment available in an appropriate reference frame, i.e. registered with the robotic arms operating in that workspace.
 The 3D reconstruction of the anatomy, including point cloud triangulation and structure from motion is presented in Section 3; monocular SLAM and 3D registration with respect to the a priori 3D map is detailed in Section 4.
 With respect to the original description of this deliverable available in the Grant Agreement, we decided to drop the automatic map update section. After receiving constructive feedbacks from medical doctors: a dynamical registration of a pre-operative map would become useless after only a few minutes due to the ever-changing nature of the anatomical scenario. We comment on this
 point in Section 5.
 Following the SARAS vision, in this work we only used available technologies (i.e. instruments) already certified and available as medical devices. Despite that, in Section 6 we discuss new technologies that can be useful in this task and their potential implementation into our project.

description: Numerical integration is a classical problem emerging in many fields of science. Multivariate integration cannot be approached with classical methods due to the exponential growth of the number of quadrature nodes. We propose a method to overcome this problem. Tensor-train decomposition of a tensor approximating the integrand is constructed and used to evaluate a multivariate quadrature formula. We show how to deal with singularities in the integration domain and conduct theoretical analysis of the integration accuracy. The reference open-source implementation is provided.

Numerical Simulation of Vortex-Induced Vibration With Bistable Springs : Consistency with the Equilibrium Constraint

description: We present results from 2-D numerical simulations based on Immersed Boundary Method of a cylinder in uniform fluid flow attached to bistable springs undergoing Vortex-Induced Vibrations (VIV). The elastic spring potential for the bistable springs, consisting of 2 potential wells, is defined by the spacing between the potential minima and the depth of the potential wells. We perform simulations of VIV with linear spring, as well as bistable springs with two different inter-well separations, over a wide range of reduced velocity. As expected, large oscillation amplitudes correspond to lock-in of the lift force with the natural frequency of the spring-mass system. The range of reduced velocity over which lock-in occurs is significantly higher for VIV with bistable springs compared to VIV with linear springs, although the maximum possible amplitude appears to be independent of the spring type. For VIV with bistable springs, the cylinder undergoes double-well oscillations in the lock-in regime. Range of reduced velocity over which lock-in occurs increases when the inter-well distance is reduced. The vortex shedding patterns and amplitude trends look similar at the same equivalent reduced velocity for the different springs. The results here are consistent with our prior theory, in which we propose a new "Equilibrium-Constraint (EC)" based on average kinetic energy budget of the structure. For a given spring potential, the intersection of natural frequency curves with the EC curve yields the possible range of reduced velocities over which lock-in should occur. Our numerical simulations show a collapse of the amplitude-versus-structure frequency data for all the simulations onto roughly the same curve, thus supporting the existence of the EC, and providing an explanation for the trends in the VIV oscillations.
description: 37 pages. The present study provides fundamental insights into VIV characteristics of bistable springs, which may be useful for designing broadband energy harvesters

description: The main result of the paper is a new representation for the Weyl Lagrangian (massless Dirac Lagrangian). As the dynamical variable we use the coframe, i.e. an orthonormal tetrad of covector fields. We write down a simple Lagrangian - wedge product of axial torsion with a lightlike element of the coframe - and show that variation of the resulting action with respect to the coframe produces the Weyl equation. The advantage of our approach is that it does not require the use of spinors, Pauli matrices or covariant differentiation. The only geometric concepts we use are those of a metric, differential form, wedge product and exterior derivative. Our result assigns a variational meaning to the tetrad representation of the Weyl equation suggested by J.B.Griffiths and R.A.Newing.

The effect of preceptorship on role transition of novice staff nurses
Creators: name: MacDonald, Bernadette
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the effect of a preceptorship program on role transition of novice staff nurses. A quasi-experimental, control group pretest post-test, design was used. Thirty-four novice staff nurses participated in the study; 20 in the preceptorship (experimental) group, and 14 in the traditional orientation (control) group. Three research hypotheses were investigated to determine whether novice staff nurses who participated in a preceptorship orientation program would: (1) demonstrate easier role transition, (2) report a higher level of job performance, and (3) demonstrate less role deprivation, than those novice staff nurses who participated in a traditional orientation program. Role transition was measured using the Six Dimension Scale of Nursing Performance (Schwirian, 1978) and the Nursing Role Conception Scale (Corwin, 1961). Participants completed the two scales during the first week of the orientation or preceptorship programs and again one-month later. Results indicated no significant differences (p<0.05) between the groups on either the Nursing Role Conception Scale or the Six Dimension Scale of Nursing Performance.
On the numerical accuracy in finite-volume methods to accurately capture turbulence in compressible flows

Year: 2021

description: The goal of the present paper is to understand the impact of numerical schemes for the reconstruction of data at cell faces in finite-volume methods, and to assess their interaction with the quadrature rule used to compute the average over the cell volume. Here, third-, fifth- and seventh-order WENO-Z schemes are investigated. On a problem with a smooth solution, the theoretical order of convergence rate for each method is retrieved, and changing the order of the reconstruction at cell faces does not impact the results, whereas for a shock-driven problem all the methods collapse to first-order. Study of the decay of compressible homogeneous isotropic turbulence reveals that using a high-order quadrature rule to compute the average over a finite volume cell does not improve the spectral accuracy and that all methods present a second-order convergence rate. However the choice of the numerical method to reconstruct data at cell faces is found to be critical to correctly capture turbulent spectra. In the context of simulations with finite-volume methods of practical flows encountered in engineering applications, it becomes apparent that an efficient strategy is to perform the average integration with a low-order quadrature rule on a fine mesh resolution, whereas high-order schemes should be used to reconstruct data at cell faces.

description: In this article, we calculate the scalar form-factors $f_{ππ}(Q^2)$ and $f_{KK}(Q^2)$ in the framework of the light-cone QCD sum rules approach. The numerical value of the $f_{ππ}(Q^2)$ changes quickly with variation of $Q^2$ near zero momentum transfer, while the $f_{KK}(Q^2)$ has rather good behavior at small momentum transfer. The value $f_{KK}(0) =2.21^{+0.35}_{-0.19} GeV$ is compatible with the result from the leading order chiral perturbation theory. At large momentum transfer with $Q^2> 6GeV^2$, the form-factor $f_{ππ}(Q^2)$ takes up the asymptotic behavior $\frac{1}{Q^2}$ approximately, while the $f_{KK}(Q^2)$ decreases more quickly than $\frac{1}{Q^2}$.

description: Tubulysins are natural anticancer molecules that directly bind and inhibit tubulin polymerization in actively dividing cells leading to apoptosis and cell death. Structurally, tubulysins are linear tetrapeptides, constituted by a natural amino acid (Ile) and three non-canonical amino acids (Mep, Tuv, and Tup). Herein, we report a convenient strategy for the practical synthesis of tubuvaline fragment of tubulysin natural products. In this approach, we describe the regioselective ring opening of a chiral aziridine 7 with vinyl Grignard reagent to obtain (R)-tert-butyl(2-methylhex-5-en-3-yl)(tosyl)carbamate 8 which was further subjected to Sharpless asymmetric dihydroxylation with AD-mix-β resulting in the formation of (2 R,4R)-4-((tert-butoxycarbonyl)amino)-2-(methoxymethoxy)-5-methylhexanoic acid 3 that was finally transformed to tubuvaline by heterocyclization.

The method exemplifies a photonic version of Sisyphus cooling, in which the matter-dressed cavity extracts energy from the particles and discharges it to the external field as a result of sudden transitions between two stable states.

description: An unprecedented method for the synthesis of 2-(prop-2-yn-1-ylidene)-2,3-dihydro-1,4-thiazepines from N-(2,4-pentadiynyl) β-enaminones is reported. Upon treatment with Lawesson’s reagent, N-(2,4-pentadiynyl) β-enaminones were thionated to furnish N-(2,4-pentadiynyl) β-enaminothiones, which immediately underwent 7-exo-dig cyclization to generate 2-(prop-2-yn-1-ylidene)-2,3-dihydro-1,4-thiazepines in one-pot. A general trend was observed for various N-(2,4-pentadiynyl) β-enaminones and cyclization proceeded with broad functional group tolerance. This operationally easy method may provide quick access to a library of functionalized 1,4-thiazepines in the field of pharmaceutical chemistry.

description: On February 6, 2016 at 21:07:19 UT, a very bright fireball was seen over the eastern part of Denmark. The weather was cloudy over eastern Denmark, but many people saw the sky light up-even in the heavily illuminated Copenhagen. Two hundred and thirty three reports of the associated sound and light phenomena were received by the Danish fireball network. We have formed a consortium to describe the meteorite and the circumstances of the fall and the results are presented in this paper. The first fragment of the meteorite was found the day after the fall, and in the following weeks, a total of 11 fragments with a total weight of 8982 g were found. The meteorite is an unbrecciated, weakly shocked (S2), ordinary H chondrite of petrologic type 5/6 (Bouvier et al. 2017). The concentration of the cosmogenic radionuclides suggests that the preatmospheric radius was rather small ~20 cm. The cosmic ray exposure age of Ejby (83 +/- 11 Ma) is the highest of an H chondrite and the second highest age for an ordinary chondrite. Using the preatmospheric orbit of the Ejby meteoroid (Spurny et al. 2017) locations of the recovered fragments, and wind data from the date of the fall, we have modeled the dark flight (below 18 km) of the fragments. The recovery location of the largest fragment can only be explained if aerodynamic effects during the dark flight phase are included. The recovery location of all other fragments are consistent with the dark flight modeling.

The influence of gas expulsion and initial mass-segregation on the stellar mass-function of globular star clusters

description: Recently de Marchi, Paresce & Pulone (2007) studied a sample of twenty globular clusters and found that all clusters with high concentrations have steep stellar mass-functions while clusters with low concentration have comparatively shallow mass-functions. No globular clusters were found with a flat mass-function and high concentration. This seems curious since more concentrated star clusters are believed to be dynamically more evolved and should have lost more low-mass stars via evaporation, which would result in a shallower mass-function in the low-mass part. We show that this effect can be explained by residual-gas expulsion from initially mass-segregated star clusters, and is enhanced further through unresolved binaries. If gas expulsion is the correct mechanism to produce the observed trend, then observation of these parameters would allow to constrain cluster starting conditions such as star formation efficiency and the time-scale of gas expulsion.

description: Recent observations of the HDO/H$_2$O ratio toward protostars in isolated and clustered environments show an apparent dichotomy, where isolated sources show higher D/H ratios than clustered counterparts. Establishing which physical and chemical processes create this differentiation can provide insights into the chemical evolution of water during star formation and the chemical diversity during the star formation process and in young planetary systems. Methods: The evolution of water is modeled using 3D physicochemical models of a dynamic star-forming environment. The physical evolution during the protostellar collapse is described by tracer particles from a 3D MHD simulation of a molecular cloud region. Each particle trajectory is post-processed using RADMC-3D to calculate the temperature and radiation field. The chemical evolution is simulated using a three-phase grain-surface chemistry model and the results are compared with interferometric observations of H$_2$O, HDO, and D$_2$O in hot corinos toward low-mass protostars. Results: The physicochemical model reproduces the observed HDO/H$_2$O and D$_2$O/HDO ratios in hot corinos, but shows no correlation with cloud environment for similar identical conditions. The observed dichotomy in water D/H ratios requires variation in the initial conditions (e.g., the duration and temperature of the prestellar phase). Reproducing the observed D/H ratios in hot corinos requires a prestellar phase duration $t\sim$1-3 Myr and temperatures in the range $T \sim$ 10-20 K prior to collapse. This work demonstrates that the observed differentiation between clustered and isolated protostars stems from differences in the molecular cloud or prestellar core conditions and does not arise during the protostellar collapse itself.

description: The choice of free parameters in network models is subjective, since it depends on what topological properties are being monitored. However, we show that the Maximum Likelihood (ML) principle indicates a unique, statistically rigorous parameter choice, associated to a well defined topological feature. We then find that, if the ML condition is incompatible with the built-in parameter choice, network models turn out to be intrinsically ill-defined or biased. To overcome this problem, we construct a class of safely unbiased models. We also propose an extension of these results that leads to the fascinating possibility to extract, only from topological data, the `hidden variables' underlying network organization, making them `no more hidden'. We test our method on the World Trade Web data, where we recover the empirical Gross Domestic Product using only topological information.

surgeon action detection

description: This document aims at describing the progress made by the SARAS project under Task 6.1 (Online surgeon action recognition), part of WorkPackage 6, which concerns the detection and recognition in real time of what actions the main surgeon performs using standard laparoscopic tools, either manually or in tele-operation via a da Vinci master robot available at University of Verona.
 The input to this component of SARAS is the video streaming in from the available laparoscopic camera. Its output is, for each video frame, a number of bounding boxes showing where the various actions of interest are taking place, with attached scores (produced by a neural network) for each action class.
Symmetry implies independence

description: Given a quantum system consisting of many parts, we show that symmetry of the system's state, i.e., invariance under swappings of the subsystems, implies that almost all of its parts are virtually identical and independent of each other. This result generalises de Finetti's classical representation theorem for infinitely exchangeable sequences of random variables as well as its quantum-mechanical analogue. It has applications in various areas of physics as well as information theory and cryptography. For example, in experimental physics, one typically collects data by running a certain experiment many times, assuming that the individual runs are mutually independent. Our result can be used to justify this assumption.

description: Graph neural networks (GNNs) have achieved tremendous success on multiple graph-based learning tasks by fusing network structure and node features. Modern GNN models are built upon iterative aggregation of neighbor's/proximity features by message passing. Its prediction performance has been shown to be strongly bounded by assortative mixing in the graph, a key property wherein nodes with similar attributes mix/connect with each other. We observe that real world networks exhibit heterogeneous or diverse mixing patterns and the conventional global measurement of assortativity, such as global assortativity coefficient, may not be a representative statistic in quantifying this mixing. We adopt a generalized concept, node-level assortativity, one that is based at the node level to better represent the diverse patterns and accurately quantify the learnability of GNNs. We find that the prediction performance of a wide range of GNN models is highly correlated with the node level assortativity. To break this limit, in this work, we focus on transforming the input graph into a computation graph which contains both proximity and structural information as distinct type of edges. The resulted multi-relational graph has an enhanced level of assortativity and, more importantly, preserves rich information from the original graph. We then propose to run GNNs on this computation graph and show that adaptively choosing between structure and proximity leads to improved performance under diverse mixing. Empirically, we show the benefits of adopting our transformation framework for semi-supervised node classification task on a variety of real world graph learning benchmarks.

description: Two approaches to the synthesis of 2-(2-oxo-5-aryl-1,2-dihydro-3H-pyrrol-3-ylidene)malononitriles (DCAA-pyrroles 1) were implemented. The first one was based on the transformation of 4-oxobutane-1,1,2,2-tetracarbonitriles 2 by the action of morpholine. The second approach was based on the reaction between protected form of 4-oxobutane-1,1,2,2-tetracarbonitriles 2 namely 2,7-dioxabicyclo[3.2.1]octane-4,4,5-tricarbonitriles 3 and morpholine. This approach involving sequential furan and pyran ring-opening of the 2,7-dioxabicyclo[3.2.1]octane moiety with further pyrrole ring-closure, resulted in a smoother formation of DCAA-pyrroles 1. The optical absorption properties of DCAA-pyrroles 1 were studied for the first time. The absorption maxima were observed in the range of 506–545 nm showing positive solvatochromism and dependence on the substituent in aryl moiety.

description: A quantum wire is fabricated on (001)-GaAs at the intersection of two overgrown cleaves. The wire is contacted at each end to n+ GaAs layers via two-dimensional (2D) leads. A sidegate controls the density of the wire revealing conductance quantization. The step height is strongly reduced from 2e^2/h due to the 2D-lead series resistance. We characterize the 2D density and mobility for both cleave facets with four-point measurements. The density on the first facet is modulated by the substrate potential, depleting a 2um wide strip that defines the wire length. Micro-photoluminescence shows an extra peak consistent with 1D electron states at the corner.
