Rhythmic Training Improves Temporal Anticipation and Adaptation Abilities in Children With Hearing Loss During Verbal Interaction
Authors: Hidalgo Céline , Pesnot-Lerousseau Jacques , Marquis Patrick , Roman Stéphane , Schön Daniele 
Published: August 2019

Purpose
In this study, we investigate temporal adaptation capacities of children with normal hearing and children with cochlear implants and/or hearing aids during verbal exchange. We also address the question of the efficiency of a rhythmic training on temporal adaptation during speech interaction in children with hearing loss.

Method
We recorded electroencephalogram data in children while they named pictures delivered on a screen, in alternation with a virtual partner. We manipulated the virtual partner's speech rate (fast vs. slow) and the regularity of alternation (regular vs. irregular). The group of children with normal hearing was tested once, and the group of children with hearing loss was tested twice: once after 30 min of auditory training and once after 30 min of rhythmic training.

Results
Both groups of children adjusted their speech rate to that of the virtual partner and were sensitive to the regularity of alternation with a less accurate performance following irregular turns. Moreover, irregular turns elicited a negative event-related potential in both groups, showing a detection of temporal deviancy. Notably, the amplitude of this negative component positively correlated with accuracy in the alternation task. In children with hearing loss, the effect was more pronounced and long-lasting following rhythmic training compared with auditory training.

Conclusion
These results are discussed in terms of temporal adaptation abilities in speech interaction and suggest the use of rhythmic training to improve these skills of children with hearing loss.

For the chirp scaling algorithm of synthetic aperture radar imaging, an efficient transmission of a large volume of data is indispensable. Prior to imaging, there is a requirement for appropriate pre‐processing of the echo signal by digital down conversion (DDC). The DDC module has to remove the carrier, having an appropriate filtering processing and down‐sampling processing. No matter what imaging mode is chosen, such as the stripmap mode, spotlight mode, and sliding spotlight, the needs of the whole imaging system are matched by setting a series of configurations about this pre‐processing module and this transmission module. The system‐on‐a‐programmable‐chip constituted by the Advanced RISC Machine and field programmable gate array (FPGA) is the perfect experimental platform to test the performance of this system. Some of the algorithms, which are more feasible for this specific project for pre‐processing in Maltab, were transplanted to FPGA using the VHSIC Hardware Description Language for functional verification. Finally, the processing results in Matlab were compared with this system to find the difference. At the same time, the time that elapsed from the 2 GB original data entering the system to the time the processed results were completely returned to the PC was also counted.

For the first time, the effects of adding hydrazine solution to tin‐oxide sol–gel to be used as an electrode in high‐performance supercapacitors have been studied. The mixed solution has been spin‐coated on stainless steel foils as substrates followed by exposing to hydrogen plasma treatment. The results show the effectiveness of adding hydrazine to tin‐oxide sol–gel, compared to pure tin‐oxide sol–gel. The electrochemical tests such as cyclic‐voltammetry and charge–discharge characteristics have been conducted, and the findings demonstrate the favourable contribution of adding hydrazine in increasing the capacitance of the supercapacitor. The physical properties of the tin‐oxide material have been analysed by means of FESEM, XRD, TEM, FT‐IR spectroscopy and Raman spectroscopy to have a better understanding of preparation procedure and better insight in material synthesis. The electrochemical tests demonstrate a high capacitance of 18 mF/cm2 for the sample treated with hydrazine during the sol–gel processing which is around 40% higher than the merely prepared tin‐oxide sample. The measured values for the capacitance versus rate show a rather linear correlation between these parameters, further corroborating an electric‐double layer‐based performance for such devices.

Published: August 2019

Residuary quinoline is a potential risk for human health in the environment, and the adsorption process is an effective way to remove this residual antibiotic. In this work, a very common guar gum was carbonised to guar gum derived carbon, which demonstrated a rich porous structure and high Brunauer–Emmett–Teller surface area (990 m2 g−1) that endowed the quinoline antibiotic with a fast adsorption rate and excellent adsorption capacity. The nonlinear fitting parameters of the adsorption isotherm indicate that the Langmuir model can accurately represent the adsorption behaviour with a maximum adsorption capacity of 425 mg g−1. The guar gum derived carbon shows great potential for the removal of antibiotics such as quinoline and other contaminants in contaminated water.
Maximum parsimony analysis of the effect of the environment on the evolution of galaxies
Authors: Fraix-Burnet Didier , D’Onofrio Mauro , Marziani Paola 
Published: August 2019

Context. Galaxy evolution and the effect of the environment are most often studied using scaling relations or regression analyses around a given property. However, these approaches do not take into account the complexity of the physics of the galaxies and their diversity.
Aims. We here investigate the effect of the cluster environment on the evolution of galaxies through multivariate, unsupervised classification and phylogenetic analyses applied to two relatively large samples from the Wide-field Nearby Galaxy-cluster Survey (WINGS), one of cluster members and one of field galaxies (2624 and 1476 objects, respectively).
Methods. These samples are the largest ones ever analysed with a phylogenetic approach in astrophysics. To be able to use the maximum parsimony (cladistics) method, we first performed a pre-clustering in 300 clusters with a hierarchical clustering technique, before applying it to these pre-clusters. All these computations used seven parameters: B − V, log(Re), nV, ⟨μ⟩e, Hβ, D4000, and log(M*).
Results. We have obtained a tree for the combined samples and do not find different evolutionary paths for cluster and field galaxies. However, the cluster galaxies seem to have accelerated evolution in the sense that they are statistically more diversified from a primitive common ancestor. The separate analyses show a hint of a slightly more regular evolution of the variables for the cluster galaxies, which may indicate they are more homogeneous compared to field galaxies in the sense that the groups of the latter appear to have more specific properties. On the tree for the cluster galaxies, there is a separate branch that gathers rejuvenated or stripped-off groups of galaxies. This branch is clearly visible on the colour-magnitude diagram, going back from the red sequence towards the blue one. On this diagram, the distribution and the evolutionary paths of galaxies are strikingly different for the two samples. Globally, we do not find any dominant variable able to explain either the groups or the tree structures. Rather, co-evolution appears everywhere, and could depend itself on environment or mass.
Conclusions. This study is another demonstration that unsupervised machine learning is able to go beyond simple scaling relations by taking into account several properties together. The phylogenetic approach is invaluable in tracing the evolutionary scenarios and projecting them onto any bivariate diagram without any a priori modelling. Our WINGS galaxies are all at low redshift, and we now need to go to higher redshfits to find more primitive galaxies and complete the map of the evolutionary paths of present day galaxies.
Postoperatives Ergebnis bei Diskopathien des Hundes in
Abhängigkeit von Rasse, Lokalisation und Erfahrung des Chirurgen: 1113
Fälle

Published: August 2019

Zusammenfassung
Gegenstand und Ziel Der Bandscheibenvorfall (BSV) ist eine häufige
neurologische Erkrankung bei Hunden, der in vielen Fällen chirurgisch behandelt
werden kann. Retrospektiv sollten bei solchen Patienten mögliche
Einflussfaktoren wie Signalement, Lokalisation oder Schweregrad des BSV sowie
Erfahrung des Operateurs auf das langfristige Behandlungsergebnis eruiert
werden.
Material und Methoden Die Auswertung umfasste die Daten von 1113 Hunden,
die von Januar 2008 bis Juli 2013 an einem oder mehreren Bandscheibenvorfällen
operiert worden waren.
Ergebnisse Hunde chondrodystropher (CD) Rassen mit einer Disposition wie
Dackel, Jack Russell Terrier und Französische Bulldogge erkrankten deutlich
früher an BSV als Hunde nicht chondrodystropher (NCD) Rassen mit signifikanten
rassespezifischen Unterschieden hinsichtlich Lokalisation und neurologischem
Schweregrad. Intakte Rüden waren überproportional häufiger betroffen, während
das Gewicht der Patienten nicht mit dem Auftreten eines BSV korrelierte. Der
neurologische Schweregrad und die Lokalisation des BSV, nicht aber die
Hunderasse oder der Erfahrungsgrad des Operateurs beeinflussten das
postoperative Behandlungsergebnis.
Schlussfolgerung und klinische Relevanz CD-Rassen erkrankten häufiger an
einem BSV als NCD-Rassen mit Französischen Bulldoggen als jüngsten Patienten.
Die meisten Vorfälle traten in der BWS (Peak in Th12/13) auf, die wenigsten in
der HWS mit rassespezifischen Unterschieden: Beagle erkrankten vorwiegend in der
HWS, Hunde kleiner NCD-Rassen, Dackel und Jack Russell Terrier in der BWS und
Französische Bulldoggen sowie Hunde großer NCD-Rassen in der LWS. Ungünstig für
das klinische Behandlungsresultat waren ein höherer neurologischer Schweregrad
und ein BSV in der BWS: Kleine NCD mit BSV Grad IV in der BWS hatten die längste
Rekonvaleszenz, während Französische Bulldoggen mit dem selben Grad in der LWS
schneller wieder lauffähig waren.

application, passage time and reisolation

Published: August 2019

Abstract
Objective This study determined the passage time and phage propagation
time of a salmonella specific phage, Felix O1, in bearded dragons, based on
reisolation from cloacal swabs and faecal samples following oral administration,
as a possible tool for reducing the zoonotic risk of salmonella from pet
reptiles. An application scheme for this phage in bearded dragons was
developed.
Material and methods Ten healthy bearded dragons (Pogona vitticeps)
were used in the study. The pH tolerance of the phage was tested and drugs were
used to evaluate their influence on the gastric pH of the reptiles. After pH
adjustment, the phage was administered orally for 12 consecutive days. Over
60 days, swabs were taken from the cloaca and examined for the presence of
phages using culture and PCR. Furthermore, faecal samples were collected for
phage quantification.
Results Felix O1 displayed no activity at pH below 2.8. A calcium- and
magnesium carbonate buffer induced an appropriate gastric pH increase for
30 minutes. Phages were reisolated for up to 24 days (mean shedding: 19 days)
after last administration. Titres between 105 and 107
plaque forming units/g faeces were detected. The animals did not show any
clinical signs related to phage application.
Conclusion and clinical relevance The study provides first results on oral
administration, passage time, and reisolation of a phage in reptiles. It could
be shown that the phage was able to replicate in the intestine, and was shed for
a prolonged period and therefore could potentially contribute to a reduction of
salmonella shedding.
Femoral Cementation in Knee Arthroplasty—A Comparison of Three Cementing Techniques in a Sawbone Model Using the ATTUNE Knee

Published: August 2019

AbstractFemoral component loosening is a rare but severe complication in total knee arthroplasty. Former studies have repeatedly demonstrated radiolucent lines behind the ventral and dorsal anchoring shields of the femoral components, which has led us to investigate this matter further. Therefore, three different cementing techniques were tested in a group of nine Sawbone samples each. These differed in the amount of cement applied on the femoral component as well as in the pressure application. Computed tomography was performed to evaluate and classify the cement penetration into the bone adjacent to the prosthesis according to the zones defined by the Knee Society scoring system. The results show significantly deeper cement penetration in all zones when a pressurizer is used. In the other two groups, no significant difference in the dorsal bevel cement penetration was noted. Additionally, no difference in ventral and dorsal cement penetrations (Zones 1 and 4) was delineated. In contrast, there was a significant difference in both the ventral bevel (Zone 2) as well as the distal anchoring surface (Zones 5–7). The use of a pressurizer results in greater cement penetration into all anchoring areas. Completely covering the component back surface results in a significantly higher penetration, which is mainly due to differences in volume. These data show significantly improved cementation results when using a pressurizer. Whether this improves the biomechanical properties and ultimately the revision rate requires further investigation.

AbstractThe purpose of this study was to analyze the effect of obesity and other clinical factors on the outcome of meniscal allograft transplantation (MAT) with transosseous fixation. A retrospective cohort study was performed on patients who underwent a MAT between 2002 and 2017. All the participants had a minimum follow-up period of 24 months. The variables assessed were age at the time of the transplant, side, sex, transplanted meniscus (lateral/medial), body mass index (BMI), smoking status, and previous surgeries. Lysholm, Tegner, and International Knee Documentation Committee (IKDC) test outcomes, and patient satisfaction were recorded. Image assessment was performed using plain standing X-rays and a follow-up magnetic resonance imaging scan. Thirty-five patients fulfilled the inclusion criteria. The mean follow-up time was of 75.7 standard deviation (SD) 43.4 months. Patients with a BMI ≥ 30 underwent medial meniscal transplants (88.9 vs. 42.3%, p = 0.022, respectively) more frequently. Obese patients had a significantly lower IKDC (48.6 SD 19.9 vs. 61.7 SD 13.1, p = 0.038, power: 57.5%) and Lysholm (60.3 SD 19.2 vs. 79.4 SD 14.3, p = 0.004, power: 88.7%) scores compared with nonobese patients. The satisfaction and Tegner scores were also lower in obese patients (55.6 vs. 80.7%, p = 0.136, and 2.8 SD 1.0 vs. 4.0 SD 1.9, p = 0.104, respectively); however, these differences were not statistically significant. Obese patients had higher rates of meniscal transplant failure compared with nonobese patients (adjusted hazard ratio: 11.8 [95% confidence interval: 1.5–91.4]). No differences were observed between obese and nonobese patients regarding age, sex, side, smoking status, and follow-up time. In this study, a BMI ≥ 30 kg/m2 resulted in higher MAT failure rates. Nonobese patients had better knee functional results compared with obese individuals.

Published: August 2019

AbstractThe purpose of this study was to analyse swimmers’ perceptual judgements of a simulated time‐to‐contact task in freestyle swimming relays.The study sample consisted of 31 national‐level swimmers of both genders (n = 18 males, 17.22 ± 1.95 yrs.; n = 13 females, 14.61 ± .76 yrs.). Participants were asked to watch two videos corresponding to the last course of a given swimmer during a competition of 4 × 100 m and 4 × 200 m freestyle events. These videos were presented with temporal occlusion correspondent to predetermined approaching distances (7.5, 5.0, and 2.5 m). Participants were required to simulate a typical position in standby for exiting the block and estimate the time‐to‐contact of the incoming swimmer by pressing a switch. A Wilcoxon test was performed to determine differences between time‐to‐contact and real contact time.The results showed that estimation of time‐to‐contact was generally lower than real contact time at all approaching distances (with occlusion) and for both genders (p < .05), except at a 7.5‐m distance in the men's 4 × 200 m (p = .744; r = .09) and at 5.0 m in both the 4 × 100 m and 4 × 200 m for the female group (p = .279, r = .22 for 4 × 100 m; p = .2453, r = .17 for 4 × 200 m). The larger variation (Δ) between estimation and real contact time was found at a 7.5 m occlusion distance in the female 4 × 100 m (p < .001; r = .82).Swimmers tend to underestimate the time‐to‐contact of the incoming swimmer, in the context of a simulated relay race. Taken together, these results highlight the importance of perceptual abilities development in swimmers to optimize their technique and effectiveness during relay starts.

Abstract
A time-delayed response of individual living organisms to information exchanged within flocks or swarms leads to the emergence of complex collective behaviors. A recent experimental setup by (Khadka et al 2018 Nat. Commun.
9 3864), employing synthetic microswimmers, allows to emulate and study such behavior in a controlled way, in the lab. Motivated by these experiments, we study a system of N Brownian particles interacting via a retarded harmonic interaction. For

, we characterize its collective behavior analytically, by solving the pertinent stochastic delay-differential equations, and for N > 3 by Brownian dynamics simulations. The particles form molecule-like non-equilibrium structures which become unstable with increasing number of particles, delay time, and interaction strength. We evaluate the entropy and information fluxes maintaining these structures and, to quantitatively characterize their stability, develop an approximate time-dependent transition-state theory to characterize transitions between different isomers of the molecules. For completeness, we include a comprehensive discussion of the analytical solution procedure for systems of linear stochastic delay differential equations in finite dimension, and new results for covariance and time-correlation matrices.

Published: August 2019

Abstract
Wepropose a scheme realizing topological insulators and quantized pumps for magnon excitations, based on strongly-interacting two-component ultracold atoms trapped in optical superlattices. Specifically, we show how to engineer the Su–Schrieffer–Heeger model for magnons using state-independent superlattices, and the Rice-Mele model using state-dependent superlattices. We describe realistic experimental protocols to detect the topological signatures of magnon excitations in these two models. In particular, we show that the non-equilibrium dynamics of a single magnon can be exploited to directly detect topological winding numbers and phase transitions. We also describe how topological (quantized) pumps can be realized with magnons, and study how this phenomenon depends on the initial magnon state preparation. Our study opens a new avenue for exploring magnonic topological phases of matter and their potential applications in the context of topological magnon transport.
Realistic sub-Rayleigh imaging with phase-sensitive measurements

Published: August 2019

Abstract
As the separation between two emitters is decreased below the Rayleigh limit, the information that can be gained about their separation using traditional imaging techniques, photon counting in the image plane, reduces to nil. Assuming the sources are of equal intensity, Rayleigh’s ‘curse’ can be alleviated by making phase-sensitive measurements in the image plane. However, with unequal and unknown intensities the curse returns regardless of the measurement, though the ideal scheme would still outperform image plane counting (IPC), i.e. recording intensities on a screen. We analyze the limits of the super-resolved position localization by inversion of coherence along an edge (SPLICE) phase measurement scheme as the intensity imbalance between the emitters grows. We find that SPLICE still outperforms IPC for moderately disparate intensities. For larger intensity imbalances we propose a hybrid of IPC and SPLICE, which we call ‘adapted SPLICE’, requiring only simple modifications. Using Monte Carlo simulation, we identify regions (emitter brightness, separation, intensity imbalance) where it is advantageous to use SPLICE over IPC, and when to switch to the adapted SPLICE measurement. We find that adapted SPLICE can outperform IPC for large intensity imbalances, e.g. 10 000:1, with the advantage growing with greater disparity between the two intensities. Finally, we also propose additional phase measurements for estimating the statistical moments of more complex source distributions. Our results are promising for implementing phase measurements in sub-Rayleigh imaging tasks such as exoplanet detection.
