Published: August 2020

Résumé
Cette étude propose une analyse de la particule additive aussi en français L2 d’apprenants avancés ayant
l’allemand comme L1. En nous basant sur un corpus de récits oraux, élicités à l’aide d’une histoire en images, nous étudierons l’expression
des liens additifs aux niveaux du répertoire lexical, de la syntaxe et de la structure informationnelle. Il sera montré que les apprenants
manifestent non seulement une forte tendance à se servir de la particule aussi afin d’exprimer les relations additives,
mais qu’ils sont en outre très enclins à marquer par des procédés syntaxiques les caractéristiques de la structure informationnelle lorsque
l’élément auquel aussi est associé, son domaine d’application (DdA), représente un topique contrastif
(« contrastive topic »). Ces caractéristiques de la production en L2 sont interprétées comme le résultat des efforts
fournis par les apprenants pour construire une narration cohérente en surface, grâce à des moyens explicites qui présentent un avantage
procédural d’un point de vue cognitif.
L’émergence du figement dans la production langagière précoce
Authors: Yaiche Sameh , Maillochon Isabelle , Bassano Dominique 
Published: August 2020

RésuméMalgré l’importance prise par le thème du figement dans la recherche récente, l’étude de la production des séquences figées ou semi-figées au tout début du langage reste encore très peu développée. Le présent article examine l’émergence du figement chez l’enfant en adoptant une approche comparative inter langues. L’étude se base sur les corpus longitudinaux de production spontanée de deux enfants, l’un francophone et l’autre arabophone tunisien, enregistrés entre 18 et 42 mois. L’objectif est d’identifier les unités complexes, de les caractériser et d’en évaluer l’importance dans la production précoce en fonction de la langue en acquisition. Les résultats montrent, malgré les profondes différences structurales opposant les langues examinées, de très nettes tendances communes que l’on peut considérer comme des caractéristiques générales du développement du figement. L’étude fait apparaître aussi des particularités dans le développement des deux enfants, tant au plan des variables générales que du lexique simple et du lexique figé, particularités que nous discutons à la lumière du contraste typologique français/arabe.
The stability for an inverse problem of bottom recovering in water-waves
Authors: Lecaros R , López-Ríos J , Ortega J H , Zamorano S 
Published: August 2020

Abstract
In this article we deal with a class of geometric inverse problem for bottom detection by one single measurement on the free surface in water-waves. We found upper and lower bounds for the size of the region enclosed between two different bottoms, in terms of Neumann and/or Dirichlet data on the free surface. Starting from the general water-waves system in bounded domains with side walls, we manage to formulate the problem in terms of the Dirichlet to Neumann operator and thus, as an elliptic problem in a bounded domain with Neumann homogeneous condition on the rigid boundary. Then we study the properties of the Dirichlet to Neumann map and analyze the called method of size estimation.
A plane wave theory of photoionization using the dipole acceleration form: predictions concerning circular dichroism in photoelectron angular distributions at high energies
Authors: Suzuki Yoshi-Ichi 
Published: August 2020

Abstract
Photoelectron angular distributions for randomly oriented atoms and molecules are characterized by the linear and circular dichroic parameters β and b
1, respectively. In the region where the photoelectron kinetic energy is several 100 eV, the values of b
1 and β are expected to be constants. In this study, we show that β for all hydrogen atom orbitals other than s orbitals approach values between 0 to 0.5 at the high-energy limit in the nonrelativistic dipole approximation and that the values can be obtained by the plane wave approximation using the dipole acceleration form. These limiting values are smaller than the widely accepted values for molecules. We discuss the implications of this result for the circular dichroism in photoelectron angular distributions of linear molecules.
Optomechanically tuned Fano resonance and slow light in a quadratically coupled optomechanical system with membranes
Authors: Wang Xiao-Yun , Si Liu-Gang , Lu Xiao-Hu , Wu Ying 
Published: August 2020

Abstract
Realizing and controlling a Fano resonance is of fundamental significance in physics and may find applications in optical switching and sensitivity-enhanced biochemical sensing. Here we present a practicable scheme to realize Fano resonance and slow light in a quadratically coupled optomechanical system with membranes. It is shown that Fano resonance generation is precisely controlled by changing the frequency detuning between the cavity field and the control field in the quadratically coupled optomechanical system, while additional membrane inside the system can considerably establish a tunable switch between a single Fano resonance and double Fano resonances. In particular, the asymmetric line shape and the number of Fano resonance can be well tuned by the reflectivity of the membranes, the wavelength of the control field and the environment temperature. Furthermore, it is also shown that the slow light effects of the transmitted probe field can be obtained under two-phonon resonance condition and the group delay of the transmitted probe field can be adjusted by the frequency and power of the control field. Our scheme may help to achieve the practical application of Fano resonances relevant to the nonlinear optics.
Interpretations of cosmic expansion: anchoring conceptions and
misconceptions
Authors: Pössel M 
Published: August 2020

Abstract
Teaching cosmology at the undergraduate or high school level requires
simplifications and analogies, and inevitably brings the teacher into contact
with at least one of the pedagogical interpretations of the expanding Universe.
The by far most popular interpretation holds that galaxies in an expanding
Universe are stationary, while space itself expands and thus causes the growing
distances that characterize cosmic expansion. The alternative relativistic
explosion interpretation regards cosmic expansion as a pattern of (relativistic)
galaxy motion. The aim of this article is to discuss the two competing
interpretations from the perspective of potential student preconceptions, taking
into account both beneficial anchoring conceptions and potentially harmful
preconceptions that can lead to misconceptions.
Pulse decomposition analysis in photoplethysmography imaging
Authors: Fleischhauer Vincent , Ruprecht Nora , Sorelli Michele , Bocchi Leonardo , Zaunseder Sebastian 
Published: August 2020

Abstract

Objective: Photoplethysmography imaging (PPGI) has gained immense attention over the last few years but only a few works have addressed morphological analysis so far. Pulse wave decomposition (PWD), i.e. the decomposition of a pulse wave by a varying number of kernels, allows for such analyses. This work investigates the applicability of PWD algorithms in the context of PPGI. Approach: We used simulated and experimental data to compare various PWD algorithms from the literature regarding their robustness against noise and motion artifacts while preserving morphological information as well as regarding their ability to reveal physiological changes by PPGI. Main results: Our experiments prove that algorithms that combine Gamma and Gaussian distributions outperform other choices. Further, algorithms with two kernels exhibit the highest robustness against noise and motion artifacts (improvement in

of 14.09 %) while preserving the morphology similarly to algorithms using more kernels. Lastly, we showed that PWD can reveal physiological changes upon distal stimuli by PPGI. Significance: This work proves the feasibility of pulse decomposition analysis in PPGI, particularly for algorithms with a low number of kernels, and opens up novel applications for PPGI. Not only for PPGI but for future research on PWD in general, our findings have importance as they elucidate differences between PWD algorithms and emphasize the importance of using initial values. To support such future research, we have released the algorithms and simulated data to the public.
Cold atmospheric single plasma jet for RONS delivery on large biological surfaces
Authors: Omran Azadeh Valinataj , Busco Giovanni , Ridou Loïck , Dozias Sébastien , Grillon Catherine , Pouvesle Jean-Michel , Robert Eric 
Published: August 2020

Abstract
Several attempts have been made to deliver reactive oxygen and nitrogen species (RONS) produced by non-thermal plasma onto large surfaces in a controllable way compatible with skin treatments. In this paper, the effect of pulse frequency, in the range 0.5–20 kHz, on the discharge behavior was studied on skin tissue models to evaluate potential treatment changes. This has been done through electrical characterization, visualization of the helium flow (by Schlieren technique), produced plasma jet modifications (ICCD imaging) and RONS measurements. The results show that, in addition to its well known important role in the production of the chemical species, the applied discharge frequency plays a very significant role in the size of the treated surface. An enhancement of NO*, OH* and O* production in the gas phase at the higher frequency is reported and assigned to the stronger mixing of the helium flow with ambient air. The efficacy of plasma jet on transporting RONS on/into agarose gel and pig skin has been evaluated. The distribution of the reactive species on the target, or passing through, is strongly dependent on the discharge frequency and consequently induces pH variations. The present study supports a new way for enlarging the treated surface by using a simple jet at high frequency in the 20 kHz range, leading, with appropriate gas flow and distance to target, to conditions of RONS production that are compatible with potential uses for biomedical or cosmetic applications.
Interface-engineering enhanced light emission from Si/Ge quantum dots
Authors: Ji Zhi-Min , Luo Jun-Wei , Li Shu-Shen 
Published: August 2020

Abstract
Si quantum dots (QDs) have a significant improvement in luminous efficiency compared with bulk Si, achieved by alleviating the forbiddance of no-phonon Γ–Γ radiative transition determined by the law of momentum conservation. Two divergent mechanisms have been proposed to account for the breakdown of momentum conservation in Si QDs, one is due to the space-confinement-induced spread of k-space wave functions associated with Heisenberg uncertainty principle Δr · Δk > 1/2, and the other is due to the interface-effect-induced intervalley mixing between indirect and direct bandgap states. Both mechanisms could cause a small overlap of the electron and hole wave functions in k-space and make vertical transitions allowed, which leads to the zero-phonon light emission. In this work, we unravel the hierarchical relationship between these two primary mechanisms in the process of zero-phonon light emission from indirect bandgap QDs, by performing semiempirical pseudopotential calculation including many-body interaction on the room-temperature luminescent properties of a series of Si, Ge, and Ge/Si core/shell QDs. We show that the space confinement mechanism is dominant in both Si and Ge indirect bandgap QDs, and the interface-induced intervalley coupling mechanism plays a minor role. While in Ge/Si core/shell QDs, the interface-induced intervalley coupling mechanism has a more pronounced contribution to enhanced light emission, implying one can further enhance light emission via engineering interface based on the intervalley coupling mechanism. Given this, we further engineer the Ge QD interface by bringing four motifs of Si/Ge multiple layers from previously inverse designed Si/Ge superlattices and core/shell nanowires for light emitters. We show that two out of four motifs always give rise to two orders of magnitude enhancement in light emission relative to the Ge and Si QDs. We demonstrate that the interface engineering can enhance light emission in indirect bandgap QDs substantially and regulate the intervalley coupling mechanism as the primary factor over the space confinement mechanism in breaking the momentum conservation law.
Half-quantum vortices on c-axis domain walls in chiral p-wave superconductors
Authors: Etter Sarah B , Huang Wen , Sigrist Manfred 
Published: August 2020

Abstract
Chiral superconductors are two-fold degenerate and domains of opposite chirality can form, separated by domain walls. There are indications of such domain formation in the quasi two-dimensional putative chiral p-wave superconductor Sr2RuO4, yet no experiment has explicitly resolved individual domains in this material. In this work, c-axis domain walls lying parallel to the layers in chiral p-wave superconductors are explored from a theoretical point of view. First, using both a phenomenological Ginzburg–Landau and a quasiclassical Bogoliubov-de Gennes approach, a consistent qualitative description of the domain wall structure is obtained. While these domains are decoupled in the isotropic limit, there is a finite coupling in anisotropic systems and the domain wall can be treated as an effective Josephson junction. In the second part, the formation and structure of half-quantum vortices on such c-axis domain walls are discussed.
Calibrating spectrometers for measurements of the spectral irradiance caused by solar radiation
Authors: Schinke Carsten , Pollex Hendrik , Hinken David , Wolf Martin , Bothe Karsten , Kröger Ingo , Nevas Saulius , Winter Stefan 
Published: August 2020

Abstract
Measuring the spectral irradiance of solar radiation is required in many fields of science and technology. In this work, we present an in-depth discussion of the measuring procedure and required corrections for such measurements. We also describe our measurement uncertainty analysis, which is based on a Monte-Carlo procedure in accordance with the Guide to the expression of uncertainty in measurement (JCGM, Paris, 2008). For this purpose, fifteen uncertainty sources are identified, analyzed and described analytically. As a specific application example, we describe the instrumentation and procedure for determining the spectral irradiance of a solar simulator at the ISO/IEC 17 025 accredited solar cell calibration laboratory ISFH CalTeC and the corresponding measurement uncertainty analysis. Moreover, we provide a Python implementation for this calculation along with the paper. We show that for state-of-the-art instrumentation, significant uncertainty contributions arise from the reference lamp (primary calibration standard), stray light and signal-to-noise ratio. If sharp spectral features are present (which is common, e.g. for Xenon lamps), spectral bandwidth and wavelength uncertainty also contribute significantly to the overall uncertainty.
Single-shot incoherent color digital holographic microscopy system with static polarization-sensitive optical elements
Authors: Tahara Tatsuki , Ito Tomoyoshi , Ichihashi Yasuyuki , Oi Ryutaro 
Published: August 2020

Abstract
We propose a digital holographic microscope for the single-shot multicolor three-dimensional (3D) image sensing of specimens illuminated by spatially and temporally incoherent white light. The proposed microscope exploits self-interference, single-shot phase-shifting incoherent digital holography, a polarization-imaging color image sensor, and static polarization-sensitive optical elements to generate two object waves with different curvature radii. The microscope does not require any spatial light modulator or a beam splitter, and can be constructed with a compact single-path optical setup. The color holographic 3D motion picture recording of spatially and temporally incoherent white light at a speed of 10 fps order is experimentally demonstrated with the proposed microscope.
Invited Commentary: Sibling-Comparison Designs, Are They Worth the Effort?
Authors: Frisell Thomas 
Published: August 2020

AbstractIn this issue of the Journal, von Ehrenstein et al. (Am J Epidemiol. 2021;190(5):728–737) add to the large and growing literature on the potentially causal association between prenatal exposure to maternal smoking and neuropsychiatric health. In addition to statewide, prospectively collected data, a particular strength was their ability to perform a sibling-comparison design, contrasting the rate of autism spectrum disorder in siblings discordantly exposed to maternal smoking. Unfortunately, the estimate from the sibling pairs could neither confirm nor refute the conclusions based on the full cohort. Interpretation was hampered by broad confidence limits, and even had power been higher, the authors acknowledge a range of potential biases that would have made it difficult to draw any firm conclusions from a similarity or difference in the sibling-pair estimate and estimate from the full cohort. Was the addition of the sibling comparison actually worth the effort? In this commentary, I will briefly summarize the benefits and limitations of this design, and, with some caveats, argue that its inclusion in the study by von Ehrenstein et al. was indeed a strength and not just an ornamentation.
The optimal discovery procedure for significance analysis of general gene expression studies
Authors: Bass Andrew J , Storey John D 
Published: August 2020

Abstract

Motivation
Analysis of biological data often involves the simultaneous testing of thousands of genes. This requires two key steps: the ranking of genes and the selection of important genes based on a significance threshold. One such testing procedure, called the optimal discovery procedure (ODP), leverages information across different tests to provide an optimal ranking of genes. This approach can lead to substantial improvements in statistical power compared to other methods. However, current applications of the ODP have only been established for simple study designs using microarray technology. Here, we extend this work to the analysis of complex study designs and RNA-sequencing studies.

Results
We apply our extended framework to a static RNA-sequencing study, a longitudinal study, an independent sampling time-series study,and an independent sampling dose–response study. Our method shows improved performance compared to other testing procedures, finding more differentially expressed genes and increasing power for enrichment analysis. Thus, the extended ODP enables a favorable significance analysis of genome-wide gene expression studies.

Finite-time analysis of vector autoregressive models under linear restrictions
Authors: Zheng Yao , Cheng Guang 
Published: August 2020

Summary
This paper develops a unified finite-time theory for the ordinary least squares estimation of possibly unstable and even slightly explosive vector autoregressive models under linear restrictions, with the applicable region $\rho(A)\leqslant 1+c/n$, where $\rho(A)$ is the spectral radius of the transition matrix $A$ in the var(1) representation, $n$ is the time horizon and $c&gt;0$ is a universal constant. The linear restriction framework encompasses various existing models such as banded/network vector autoregressive models. We show that the restrictions reduce the error bounds via not only the reduced dimensionality, but also a scale factor resembling the asymptotic covariance matrix of the estimator in the fixed-dimensional set-up: as long as the model is correctly specified, this scale factor is decreasing in the number of restrictions. It is revealed that the phase transition from slow to fast error rate regimes is determined by the smallest singular value of $A$, a measure of the least excitable mode of the system. The minimax lower bounds are derived across different regimes. The developed non-asymptotic theory not only bridges the theoretical gap between stable and unstable regimes, but precisely characterizes the effect of restrictions and its interplay with model parameters. Simulations support our theoretical results.

Published: August 2020

Abstract
A clarification is given regarding recent polemic over our original published study. The author of this polemic has claimed a few issues about the computations and data listed in our work such as choosing the wrong temperature unit and the incorrect calculation of molar heat of vaporization. Here it is elaborated the complete data and computations that are not included in the original paper, and list out also the parameters, which may be the source of difference in reported molar heat of vaporization through inverse gas chromatography methods and other conventional methods. It is showed that there are no wrong calculations or reports of molar heat of vaporization in our published paper.
Attributable Length of Stay, Mortality Risk, and Costs of Bacterial Health Care–Associated Infections in Australia: A Retrospective Case-cohort Study
Authors: Lee X J , Stewardson A J , Worth L J , Graves N , Wozniak T M 
Published: August 2020

Abstract

Background
Unbiased estimates of the health and economic impacts of health care–associated infections (HAIs) are scarce and focus largely on patients with bloodstream infections (BSIs). We sought to estimate the hospital length of stay (LOS), mortality rate, and costs of HAIs and the differential effects on patients with an antimicrobial-resistant infection.

Methods
We conducted a multisite, retrospective case-cohort of all acute-care hospital admissions with a positive culture of 1 of the 5 organisms of interest (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, or Enterococcus faecium) from 1 January 2012 through 30 December 2016. Data linkage was used to generate a data set of statewide hospital admissions and pathology data. Patients with bloodstream, urinary, or respiratory tract infections were included in the analysis and matched to a sample of uninfected patients. We used multistate survival models to generate LOS, and logistic regression to derive mortality estimates.

Results
We matched 20 390 cases to 75 635 uninfected control patients. The overall incidence of infections due to the 5 studied organisms was 116.9 cases per 100 000 patient days, with E. coli urinary tract infections (UTIs) contributing the largest proportion (51 cases per 100 000 patient days). The impact of a UTI on LOS was moderate across the 5 studied pathogens. Resistance significantly increased LOS for patients with third-generation cephalosporin-resistant K. pneumoniae BSIs (extra 4.6 days) and methicillin-resistant S. aureus BSIs (extra 2.9 days). Consequently, the health-care costs of these infections were higher, compared to corresponding drug-sensitive strains.

Conclusions
The health burden remains highest for BSIs; however, UTIs and respiratory tract infections contributed most to the health-care system expenditure.
