Published: September 2020

Quoi de commun entre un marionnettiste et une doctorante en physique, un couple de clowns et une physico-chimiste des matériaux, une vidéaste et un hydrodynamicien ? Une passion commune pour les films, bulles et mousses de savon, et une volonté tenace de construire l’interface artscience pour que les deux parties en retirent des idées fructueuses.
Un atelier « Spectacle vivant et sciences » a réuni des artistes et des chercheurs en octobre 2017, et à nouveau en novembre 2019 au Laboratoire de Physique des Solides, à l’Université Paris-Saclay.

Frühes interdisziplinäres Assessment zur Sekundärprävention chronischer Schmerzen
Authors: Kaiser Ulrike , Lindena Gabriele ,   PAIN2020
Published: September 2020

ZusammenfassungSchmerz ist ein multikausales biopsychosoziales Phänomen. Das bedeutet für eine angemessene Versorgung ein entsprechendes interdisziplinäres Vorgehen in Diagnostik und Therapie. Faktoren, die bei bestehenden Schmerzen zu einer Chronifizierung beitragen können, sollten frühzeitig im Versorgungsalltag berücksichtigt werden. Dafür sind sektorenübergreifende Vernetzungen sowie interdisziplinäre Versorgungsangebote von großer Bedeutung.
COVID-19-assoziierte Pneumonie trotz persistierend negativen PCR-Tests aus oropharyngealen Abstrichen
Authors: Hornuss D. , Laubner K. , Monasterio C. , Thimme R. , Wagner D. 
Published: September 2020

Zusammenfassung
Anamnese und klinischer Befund Ein 46-jähriger Bauarbeiter stellte sich bei seit ca. 7 Tagen bestehender Infektsymptomatik mit Fieber und teilweise produktivem Husten sowie 2-maliger orthotstatischer Synkope in der Notaufnahme vor. Ambulant war bereits eine orale antibiotische Therapie über 5 Tage mit Sultamicillin durch den Hausarzt eingeleitet worden, die zu keiner Beschwerdebesserung führte. In der klinischen Untersuchung zeigten sich hypertone Blutdruckwerte bei bekannter arterieller Hypertonie, ansonsten unauffällige Vitalparameter sowie pulmonal feinblasige Rasselgeräusche links basal.
Untersuchungen und Diagnose Laborchemisch präsentierten sich erhöhte Werte für LDH sowie pro-BNP und CRP bei normwertigen Leukozyten und normwertigem Procalcitonin. Bei Verdacht auf Pneumonie wurde zunächst ein konventionelles Röntgenbild der Lunge durchgeführt, das laterale Verschattungen in beiden Lungen zeigte, verdächtig auf eine atypische Pneumonie. Bei initial negativem Rachenabstrich trotz typischer klinischer, radiologischer und laborchemischer Konstellation erfolgte ein erneuter tiefer Rachenabstrich auf SARS-CoV-2, welcher ebenfalls negativ ausfiel. In der nachgeschalteten CT-Untersuchung des Thorax zeigten sich für COVID-19 typische bipulmonale laterale milchglasartige Infiltrate, woraufhin ein dritter Rachenabstrich durchgeführt wurde, der erneut negativ blieb. Nach Asservierung und PCR-Analyse von Sputum konnte schließlich der Nachweis von SARS-CoV-2 erbracht und die Diagnose einer COVID-19-assoziierten Pneumonie gesichert werden.
Therapie und Verlauf Es erfolgte die stationäre Aufnahme zur Infekt- und Synkopen-Abklärung. Bei zunächst noch ausstehendem Ergebnis des Rachenabstrichs auf SARS-CoV-2 wurde der Patient prophylaktisch isoliert. Bei Verdacht auf eine mögliche bakteriell-superinfizierte Pneumonie wurde eine intravenöse antibiotische Therapie mit Ampicillin/Sulbactam eingeleitet, welche nach 3 Tagen bei fehlenden Hinweisen auf bakterielle Erreger beendet wurde. Nach Diagnosesicherung erfolgte bei bereits eingetretener klinischer Rekonvaleszenz keine antivirale Therapie. Der Patient wurde 17 Tage nach initialem Symptombeginn ohne weitere Quarantäne-Auflagen nach Hause entlassen.
Folgerung Die Kasuistik beschreibt einen Fall von COVID-19, bei dem trotz typischer klinischer Symptomatik sowie typischen radiologischen und laborchemischen Befunden ein Virusnachweis in mehrfach korrekt durchgeführten tiefen Rachenabstrichen nicht möglich war. Erst eine Sputum-Analyse erbrachte den Nachweis der viralen RNA und sicherte die Diagnose. Bei begründetem klinischem Verdacht auf COVID-19 sollte daher bei negativen Rachenabstrichen zum sicheren Ausschluss eine Analyse von tiefen Atemwegssekreten (Sputum, bronchoalveoläre Lavage, Trachealsekret) oder Stuhl erfolgen.

Published: September 2020

AbstractObjective To study the molecular basis of human coagulation factor XII (FXII) deficiency in a Chinese family.Methods Routine blood coagulation indexes were detected by a one-stage clotting method, whereas FXII antigen was detected by enzyme linked immunosorbent assay. DNA sequencing was applied to find mutations in the F12 gene. Bioinformatics and conservative analyses were performed to analyze possible effects of the mutation.Results The proband had significantly prolonged activated partial thromboplastin time (141.9 seconds), and her FXII clotting activity was decreased to 5%. Genetic analysis revealed that the propositus carried a heterozygous missense mutation c.797G > A in exon 8 resulting in Cys247Tyr and deletion mutation c.809_811delACA in exon 9 resulting in 252delAsn. Bioinformatics results indicated that the mutation had affected the function of the protein.Conclusion The c.797G > A heterozygous missense variation and the c.809_811delACA heterozygous deletion variation are associated with decreased FXII levels in this family, of which c.797G > A is first reported in the world.

Published: September 2020

AbstractLanguage barriers have been reported to have a detrimental effect on various
outcomes in paediatric care, such as therapy adherence, and may even cause
medical treatment errors. To address this issue, we developed a set of 63 cards
with which a wide range of specific messages can be conveyed nonverbally in a
clinical context. The conceptualization of the tool involved multiple phases. In
Study 1, we held a workshop with 11 children and adolescents between 8 and 19
years that had received treatment for oncological conditions to gain an
understanding of the specific challenges. In Study 2, we presented a first
prototype to 3 children and 14 adults; participants were asked to rate the cards
on multiple dimensions. Based on information from the previous trials, we
developed a second prototype and asked 10 children and 7 adults to rate the
cards on multiple dimensions. In this multidisciplinary approach in addition to
our experts of clinical psychology we involved patient advocators and graphic
designers in the process to achieve high feasibility and comprehensibility;
based on the workshop, expert consensus surveys, data gathered in evaluation,
all prototypes and the final card set were developed in close collaboration.
Participants had little difficulty interpreting the cards and rated the
information content as adequate. Importantly, a majority of participants
indicated that they would keep using the tool during their stay at the hospital.
Overall, the evaluation implied high acceptance and usability. The final card
set is a promising communication tool in clinical paediatric settings with
various language barriers. Further research should address how patient outcomes
are impacted by using the tool.

Published: September 2020

Objective The aim of this study is to compare neonatal mortality and morbidity in multiple and singleton preterm/very low birthweight (PT/VLBW) multiethnic Asian infants.Study Design Cohort study of 676 singleton and 299 multiple PT/VLBW infants born between 2008 and 2012 at KK Women's and Children's Hospital, the largest tertiary perinatal center in Singapore with further stratification by gestational ages 23 to 25 (Group 1), 26 to 28 (Group 2), and ≥29 (Group 3) weeks. Outcome measures included predischarge mortality and major neonatal morbidity.Results Overall survival to discharge was comparable for singletons 611/676 (90%) and multiples 273/299 (91%). Use of assisted reproductive technologies (47 vs. 4%), antenatal steroids (80 vs. 68%), and delivery by cesarean section (84 vs. 62%) were significantly higher (p < 0.001) in multiples while pregnancy induced hypertension (8.7 vs. 31.6%, p < 0.001) and maternal chorioamnionitis (31 vs. 41%, p < 0.01) were seen less commonly compared with singleton pregnancies. Survival was comparable between singletons and multiples except for a lower survival in multiples in Group 2 (81.7 vs. 92.4%, p = 0.007). Major neonatal morbidities were comparable for multiples and singletons in the overall cohort. Presence of hemodynamically significant patent ductus arteriosus (HsPDA) requiring treatment (88.9 vs. 72.5%), air leaks (33 vs. 14.6%, p = 0.02), NEC (30 vs. 14.6%, p = 0.04), and composite morbidity (86 vs. 66%, p = 0.031) were significantly higher in multiples in Group 1. A significantly higher incidence of HsPDA (68.1 vs. 52.4%, p = 0.008) was also observed in multiples in Group 2. Multiple pregnancy was not an independent predictor of an adverse outcome on regression analysis (OR: 0.685, 95% confidence interval: 0.629–2.02) even in GA ≤25 weeks.Conclusion Neonatal mortality and morbidity were comparable in our cohort of PT/VLBW singletons and multiple births, but preterm multiple births ≤25 weeks had a higher incidence of neonatal morbidity.Key Points
Homeostatic mechanisms regulate distinct aspects of cortical circuit dynamics
Authors: Wu Yue Kris , Hengen Keith B. , Turrigiano Gina G. , Gjorgjieva Julijana 
Published: September 2020

Significance
Despite decades of intense studies on homeostasis, network properties undergoing homeostatic regulation remain elusive. Furthermore, whether diverse forms of homeostatic plasticity are simply redundant or serve distinct functions is unclear. Here, our data show that functional correlations are subject to homeostatic regulation, both in terms of average amplitude and their structure. A computational model demonstrates that synaptic scaling is essential for the restoration of correlations and network structure, whereas intrinsic plasticity is crucial for the recovery of firing rates after perturbations, suggesting that synaptic scaling and intrinsic plasticity distinctly contribute to homeostatic regulation.
Tunable layered composites based on magnetoactive elastomers and piezopolymer for sensors and energy harvesting devices
Authors: Makarova L A , Alekhina Yu A , Isaev D A , Khairullin M F , Perov N S 
Published: September 2020

Abstract
The novel layered structures comprising piezoelectric polymer and magnetoactive elastomer (MAE) were developed and investigated. The influence of iron particles content in the elastomeric layer, its thickness and Young’s modulus of silicone on the multiferroic properties of the structures were analyzed. The investigation included the experimental and numerical characterization of the magnetoelectric effect. The giant values of bending deformations of MAEs in the external gradient magnetic field led to giant values of induced voltage (up to nearly 650 mV) in the composite. The displacement of ferromagnetic particles inside the elastomeric matrix under gradient magnetic field became the main basis for numerical modelling. The molecular dynamic method, ‘virtual springs’ method and Verlet algorithm were used to obtain the results of the numerical experiment. The energy transformation and magnetic field response in the novel composite allow it to be used in sensors and energy-harvesting devices.
Full-space polarization-regulated lightwave steering via single-layer metasurfaces
Authors: Yang Hui , Xie Zhenwei , Zhou Zhangyu , Yuan Xiaocong 
Published: September 2020

Abstract
Metasurfaces can offer unprecedented superiority in manipulating the wavefront of electromagnetic waves and have attracted much attention around the world. However, to date, most of the metasurfaces reported only operate in either transmission or reflection space, leaving half of the space unexplored. Here we propose a general scheme for designing full-space polarization-regulated wavefront steering via single-layer metasurfaces. Specifically, the designed metasurface can change its functionality and working space (from transmission space to reflection space and vice versa) by varying the incident polarization. For a proof of concept, we demonstrate numerically two full-space polarization-regulated metasurfaces. As incident x-polarized light changes to y-polarized light, the functionality of two devices is switched from a reflected metalens and an Airy bean generator to a transmitted focusing vortex generator and a metalens, respectively. Here the design strategy is generalized and can be adapted to design other polarization-regulated meta-devices at other wavelengths. In regard to wavefront control, these results significantly expand the scope of metasurfaces, providing new possibilities to develop full-space multifunctional meta-devices.
The luminosity constraint in the era of precision solar physics
Authors: Vescovi Diego , Mascaretti Carlo , Vissani Francesco , Piersanti Luciano , Straniero Oscar 
Published: September 2020

Abstract
The luminosity constraint is a very precise relationship linking the power released by the Sun as photons and the solar neutrino fluxes. Such a relation, which is a direct consequence of the physical processes controlling the production and the transport of energy in the solar interior, is of great importance for the studies of solar neutrinos and has a special role for the search of neutrinos from the CNO cycle, whose first detection with a 5σ significance has been recently announced by the Borexino collaboration. Here we revise the luminosity constraint, discussing and validating its underlying hypotheses, in the light of latest solar neutrino and luminosity measurements. We generalize the current formulation of the luminosity constraint relation so that it can be easily used in future analysis of solar neutrino data, and we provide a specific application showing the link between CNO and pp neutrino fluxes.

Published: September 2020

Abstract
High spin states in 104Pd were populated via 94Zr(13C, 3nγ) fusion-evaporation reaction at a beam energy of 55 MeV. The Indian National Gamma Array was utilized to detect the de-exciting γ-rays. Lifetimes of states in the negative parity bands have been determined using the Doppler shift attenuation method. The present lifetime results suggest a moderate quadrupole deformation (β
2 ≈ 0.2) for the negative parity bands. The Woods–Saxon total Routhian surface calculations have also been carried out which predicted a similar deformation for these bands. In addition, lifetimes of states in the positive parity band have also been determined. Present results found in agreement with the earlier reported values of lifetimes and hence agreed with the antimagnetic rotational character of the band as interpreted earlier.

Published: September 2020

Abstract
A reliable data-driven tool condition monitoring system is more and more promising for cutting down on machine downtime and economic losses. However, traditional methods are not able to address machining big data because of low model generalizability and laborious feature extraction by hand. In this paper, a novel deep learning model, named multi-frequency-band deep convolution neural network (MFB-DCNN), is proposed to handle machining big data and to monitor tool condition. First, samples are enlarged and a three-layer wavelet package decomposition is applied to obtain wavelet coefficients in different frequency bands. Then, the multi-frequency-band feature extraction structure based on a deep convolution neural network structure is introduced and utilized for sensitive feature extraction from these coefficients. The extracted features are fed into full connection layers to predict tool wear conditions. After this, milling experiments are conducted for signal acquisition and model construction. A series of hyperparameter selection experiments is designed for optimization of the proposed MFB-DCNN model. Finally, the prediction performance of typical models is evaluated and compared with that of the proposed model. The results show that the proposed model has outstanding generalizability and higher prediction performance, and a well designed structure can remedy the absence of complicated feature engineering.

Published: September 2020

Abstract

In-situ monitoring of soft soil strength development is of great significance in artificial ground freezing (AGF) projects. It can not only help engineers estimate the soil freeze-thaw status, but also provide useful data for predicting and controlling the concurrent adverse effects which may cause serious engineering accidents. As a useful nondestructive testing method, the electromechanical impedance (EMI) method has already been extensively employed in a wide range of monitoring applications. In this research, the applicability of the EMI method was extended to monitoring the soil freeze-thaw process and the strength development for the first time. Through the experimental research, a lead zirconate titanate transducer was adopted to measure the changes in the conductance signature during the freeze-thaw process. Furthermore, the lateral and vertical shifts of the resonance peak in the electromechanical spectra and three statistic indices were employed as indicators for the quantitative evaluation of the unconfined compressive strength of the soil specimen. The experimental results verified the effectiveness and reliability of the proposed method in monitoring the soil compressive strength development. This method will have broad prospects in in-situ monitoring of the soil strength development in AGF projects.
Unusual effects of nanowire-nanowire junctions on the persistent photoconductivity in SnO2 nanowire network devices
Authors: Costa I M , de Araújo E P , Arantes A N , Zaghete M A , Chiquito A J 
Published: September 2020

Abstract
The persistent photoconductivity (PPC) effect is a commonly observed behavior in SnO2 nanostructures. Here we described and studied this effect through a comparative study, based on measurements of electronic transport using network as well as single devices built from SnO2 nanowires under different experimental conditions. At room temperature, the PPC effect was observed to be more accentuated in single nanowire devices. It was found that nanowire-nanowire junctions play a fundamental role in the device behavior: the decay time of nanowire network (τ = 52 s) is about three orders of magnitude lower than those of single nanowire (τ = 4.57 × 104 s). Additionally, it was confirmed that the PPC effect was directly related to the amount of oxygen present in the environment and it is destroyed with increasing temperature. Furthermore, the PPC effect was interpreted based on the surface effect that depends on the capture/emission of electrons by the surface states.
A first-principles study of Janus monolayer TiSSe and VSSe as anode materials in alkali metal ion batteries
Authors: Xiong Fen , Chen Yue 
Published: September 2020

Abstract
Anode materials play an important role in the performance of rechargeable batteries and have been attracting much research interest. In this work, we have investigated the electrochemical properties of two-dimensional (2D) Janus MSSe (M = Ti or V) for potential applications as anode materials in alkali metal ion batteries from density functional theory (DFT), following the recent successful synthesis of 2D Janus MoSSe. Our DFT calculations suggest that 2D Janus TiSSe and VSSe are stable in the 1T phase and 1H phase, respectively. It is found that alkali metal atoms X (X = Li, Na or K) can be stably adsorbed on the surfaces of Janus MSSe, and have low diffusion energy barriers. Additionally, small volume changes are observed in Janus MSSe after the adsorption of alkali metal atoms. It is predicted that the MSSe-2X systems have low open circuit voltages and high capacities. Our results suggest that 2D Janus TiSSe and VSSe are potential anode materials for alkali metal ion batteries.
Hard template synthesis of 2D porous Co3O4 nanosheets with graphene oxide for H2O2 sensing
Authors: Zhang Xinmeng , Zhao Yuanxiao , Huang Shuohan , Wu Yuanting , Mao Zixuan , Wang Xiufeng 
Published: September 2020

Abstract
In this work, we used graphene oxide (GO) as a template that was removed by calcination to finally successfully prepare Co3O4 with 2D porous nanostructure. The results show that 2D porous structure Co3O4 nanosheets were only prepared at pH = 2. After electrochemical tests, the as-prepared Co3O4 nanosheets showed electrochemical properties that are highly suitable for H2O2 detection, such as high current response, short response time (less than 3 s), wide linear range (0.388–44.156 mM), low limit of detection (2.33 μM) and high sensitivity (0.0891 mA mM−1 cm−2). These excellent properties are mainly due to GO, as a 2D template, which connects Co3O4 nanoparticles to each other on a 2D plane, preventing the agglomeration of Co3O4 nanoparticles. The abundant pores between Co3O4 nanoparticles can greatly increase the reaction between the nanoparticles and H2O2 molecules.

Published: September 2020

Abstract
Two-dimensional layered metal chalcogenides (LMCs) are widely used in battery anode materials, energy conversion, and semiconductor devices, because of their high energy storage characteristics, high thermoelectric characteristics, and large electron mobility. SnSe2 as a kind of LMC has strong nonlinear optical characteristics. However, its research on dissipative system dynamics as a saturable absorber has not been studied. In this work, we obtained SnSe2 nanosheets using lithium ion intercalation and we reported a passively mode-locked fiber laser with SnSe2 as a saturable absorber to achieve the dissipative soliton in a dissipative system. Due to the high third-order nonlinearity of SnSe2, the evolution of square wave pulses from 2 to 16 ns was obtained in a fiber ring cavity. Through adjusting the polarization state, the evolution phenomenon of soliton rain, the soliton rain phenomenon with a spectrum of dual-wavelengths, and a bound state harmonic phenomenon with a frequency of 313 MHz were obtained. Therefore, the strong nonlinear fiber laser based on SnSe2 provides a good platform for study the pulsation, explosion, rainfall and other phenomena.
