Les fondateurs du secteur et l’investissement du travail dans la cité
Authors: Bydlowski Sarah 
Published: July 2022

La création du secteur a d’emblée pour objectif la lutte contre l’enfermement asilaire, l’insertion des patients dans la cité. Il s’agit aussi de faire front contre l’illettrisme, les inégalités sociales et toute ségrégation. La psychiatrie publique se met ainsi à la portée du malade, dans un mouvement liant indissociablement traitement et prévention.L’application de la psychanalyse à l’enfant modifie radicalement les conceptions psychopathologiques de ses troubles et l’action thérapeutique entreprise. Dans cette perspective, le symptôme ne prend sens qu’en tenant compte, tant de l’environnement que de la personnalité et des modalités relationnelles de l’enfant, autrement dit de la réalité psychique de l’enfant en interaction avec les réalités psychiques de ceux qui l’entourent.Pour les fondateurs du secteur, il s’agit de permettre à la fois de sensibiliser ceux qui s’occupent d’enfants à leurs besoins et à leurs difficultés, de connaître et de traiter précocement les enfants dont l’état constitue un risque pour leur avenir. L’idée est que les relations engagées avec le professionnel de terrain permettront des identifications réciproques, un plaisir partagé, autour de situations parfois inextricables. Le psychiatre qui voit des enfants en difficulté se trouve confronté à des problèmes sociaux, politiques et économiques qu’il ne maîtrise pas, mais avec lesquels il doit travailler. Il s’agit d’aller sur place, sur le lieu de l’école, d’observer, en collaboration avec les maîtres, les élèves, nos patients, dans une perspective préventive.

Published: July 2022

We present an experimental investigation of methylammonium lead tribromide single crystals in the orthorhombic, tetragonal, and cubic phases based on inelastic and deep inelastic neutron scattering experiments. We show how the average hydrogen nuclear kinetic energy, mainly affected by zero-point vibrational energies, shows differences larger compared to the changes simply related to temperature effects when moving from one phase to another. In particular, the Gaussian contribution to the average nuclear kinetic energy is larger in the tetragonal phase compared to the cubic and orthorhombic ones. Moreover, we find that the vibrational densities of states of MAPbBr3 single crystals in the orthorhombic phase are compatible with previously reported results on powder samples, and that the only vibrational modes that show slightly different frequencies compared to MAPbI3 are those in the energy range between 100 and 300 cm−1, related to librational/rotational modes. As these shifts are of about 10 cm−1 and do not affect any higher-energy vibrational mode, we conclude that the zero-point energies and average nuclear kinetic energies in the two-hybrid organic/inorganic perovskites are expected to be approximately the same within a harmonic framework.

Abstract
This paper describes fabrication of a laminated film vibrator that uses an ultra-thin micro-electric mechanical system (MEMS) and the effect of lamination on the actuator. The thickness of the ultra-thin MEMS actuator fabricated by ultra-thin MEMS technology was 7.26 µm, making it especially flexible. The vibrator was actuated by applying voltage on a lead zirconate titanate (PZT) thin film. Then, we applied a lamination method to package the actuator. However, the lamination structure influenced the mechanical characteristics of the vibrator. Therefore, we evaluated the effect of the lamination structure on the static and dynamic characteristics of the laminated film vibrator. Four types of laminated film vibrators with different layer structures were prepared, and their displacements and velocity were measured when DC and AC voltages were applied. The maximum displacement of the cantilevers constructed from the laminated film vibrator (PZT: 11 mm × 11 mm) was 113.3 µm at 40 V DC. This result is in good agreement with the calculated result. Furthermore, the dynamic characteristics from both the experimental and simulated results confirmed that the resonant frequency of the laminated film vibrator depends on the film structure. This means the dynamic characteristics can be adjusted to suit the application. Applications of this laminated film actuator include use as a flexible hybrid electronics haptic device for monitoring vital signs.

Abstract
Gallium oxide (Ga2O3) is a representative of ultra-wide bandgap semiconductors, with a band gap of about 4.9 eV. In addition to a large dielectric constant and excellent physical and chemical stability, Ga2O3 has a theoretical breakdown electric field strength of more than 8 MV cm−1, which is 27 times more than that of Si and about twice as large as that of SiC and GaN. It is guaranteed that Ga2O3 has irreplaceable applications in ultra-high-power (1–10 kW) electronic devices. Unfortunately, due to the difficulty of p-type doping of Ga2O3, the full Ga2O3-based bipolar devices face more difficulties, and the unipolar Ga2O3 power Schottky diodes are feasible, but substantial progress has been made in recent years. In this article, we review the advanced progress and important achievements of the state-of-the-art Ga2O3-based power Schottky barrier diodes, and provide staged guidance for the further development of Ga2O3 power devices. Multiple types of device architectures, including basic structure, edge terminal processing, field-plated, trench and heterojunction p–n structure, will be discussed in detail.

Published: July 2022

Abstract
Cold atmospheric plasma induces various dose-dependent effects on living cells, from proliferation to necrosis. These effects are of interest in the field of therapeutic flexible endoscopy, although implementing an effective plasma delivery system represents a technical challenge. This work studies the impact of critical parameters on plume intensity, delivered reactive species (RS), and current administered to the target for the use of plasma in endoscopy. A 2 m long dielectric barrier discharge plasma jet was studied upon nano-pulsed high voltage excitation to increase plasma reactivity. The peak voltage, gas gap, pulse repetition frequency, and pulse width were varied while the power dissipated by the system and the optical emissions (with imaging and spectrometry) were measured. Two configurations were compared: the first one with the plume exiting freely in air, and the second one with the plume impinging an electrical equivalent of the human body. Finally, the current flowing through the capillary was measured at regular intervals along the tube with a Rogowski coil. Results show that (a) a conductive target increases the ratio of RS produced over the dissipated power, (b) increasing the pulse repetition frequency does not improve the RS production per pulse (e.g. through a synergetic, memory effect), (c) increasing the pulse width does not influence RS production but increases the dissipated power, and (d) current linearly leaks through the tube walls, and leaks are lower with nano-pulsed compared to sinusoidal excitation. Reactance and capacitance values of the system are analyzed based on the electrical equivalent circuit approach. Finally, displacement and discharge currents are discussed to bring power dissipation mechanisms to light and compare them between configurations. The conclusions drawn are important for the future design of safe and effective endoscopic plasma devices.
Investigation of empirical heat capacity in hot-rotating A ∼ 200 nuclei

Published: July 2022

Abstract
The empirical heat capacities of some hot-rotating A ∼ 200 nuclei (184Re, 200Tl, 211Po, and 212At) have been investigated by combining the angular-momentum dependent back-shifted Fermi gas (BSFG) model of nuclear level density (NLD) with the experimental NLD data extracted from the neutron-evaporation spectra at the average total angular momentum ⟨J⟩ = 12 ℏ. The parameters of the BSFG are obtained by fitting its NLD to the corresponding measured data using an advanced package of program modeling (CPM) provided by Python feature of IBM decision optimization CPLEX. The results obtained show that the shell correction plays an important role in the formation of empirical S-shaped heat capacity, which serves as a fingerprint for the pairing phase transition in finite nuclear systems. The 184Re nucleus, which is deformed and has small shell correction, exhibits a weaker S-shaped heat capacity than the remaining three spherical 200Tl, 211Po, and 212At nuclei that have large shell effects. This result contrasts with that recently predicted by the microscopic exact pairing plus independent-particle model at finite temperature (EP + IPM), in which the S-shaped heat capacity was predicted in 184Re only. This discrepancy between the heat capacities obtained within the BSFG and EP + IPM models suggests that an NLD model capable of well describing the experimental data while also having intrinsic and as complete as possible physical interpretations is still required in order to provide the exact description of nuclear thermodynamic quantities. In addition, more experimental NLD data in other mass and higher energy regions are also demanded.
The Pierre Auger exotic events and axion quark nuggets
Authors: Zhitnitsky Ariel 
Published: July 2022

Abstract
The Pierre Auger observatory have reported (Abreu et al 2021 PoS ICRC2021 p 395; Colalillo 2019 EPJ Web Conf.
197 03003; Colalillo 2017 PoS ICRC2017 p 314) observation of several exotic cosmic ray (CR)-like events which apparently related to thunderstorms. These events are much larger in size than conventional CR events, and they have very distinct timing features. A possible nature of the observed phenomenon is still a matter of active research and debates as many unusual features of these exotic events (EEs) are hard to explain. In particular, the frequency of appearance of these EEs is very low (less than 2 events yr−1), in huge contrast with a typical rate of a conventional lightning strikes in the area. We propose that the observed EEs can be explained within the so-called axion quark nugget (AQN) dark matter model. The idea is that the AQNs may trigger and initiate a special and unique class of lightning strikes during a thunderstorm as a result of ionization of the atmospheric molecules along its path. The corresponding AQN-induced lighting flashes may show some specific features not shared by typical and much more frequent conventional flashes. We support this proposal by demonstrating that the observations (Abreu et al 2021 PoS ICRC2021 p 395; Colalillo 2019 EPJ Web Conf.
197 03003; Colalillo 2017 PoS ICRC2017 p 314), including the frequency of appearance and time duration are consistent with observations. We also comment on possible relation of AUGER EEs with the Telescope Array bursts and the terrestrial gamma ray flashes. We list a number of features of the AQN-induced EEs (such as specific radio pulses synchronized with these events) which can be directly tested by future experiments. We also suggest to use distributed acoustic sensing instruments to detect the acoustic pulses which must be synchronized with AUGER EEs.

Published: July 2022

Abstract
With the advancement toward commercialization of quantum dots (QDs) in the field of lighting and display, improving the performance of Cd-free QDs and related quantum dot light-emitting diodes (QLEDs) becomes necessary. Thus far, the performance of ZnTeSe- and InP-based blue and red QLEDs has been significantly improved by optimizing QDs emitting materials and device structure. However, as one of the three primary color sources, the performance of green InP-based QLEDs still lags behind that of blue and red Cd-free QLEDs. Herein, this review discusses the latest progress of green InP-based emitting materials and corresponding QLEDs, covering the engineering of InP core, the optimization of nanostructure and surface ligands of core/shell QDs, as well as the majorization of device architecture and carrier transport materials. Finally, some challenges and possible development directions of green InP-based QDs and related QLEDs are also identified, which may speed up the commercialization process of Cd-free QDs and corresponding QLEDs.
Derivation and analysis of a phase field crystal model for a mixture of active and passive particles
Authors: Vrugt Michael te , Holl Max Philipp , Koch Aron , Wittkowski Raphael , Thiele Uwe 
Published: July 2022

Abstract
We discuss an active phase field crystal (PFC) model that describes a mixture of active and passive particles. First, a microscopic derivation from dynamical density functional theory is presented that includes a systematic treatment of the relevant orientational degrees of freedom. Of particular interest is the construction of the nonlinear and coupling terms. This allows for interesting insights into the microscopic justification of phenomenological constructions used in PFC models for active particles and mixtures, the approximations required for obtaining them, and possible generalizations. Second, the derived model is investigated using linear stability analysis and nonlinear methods. It is found that the model allows for a rich nonlinear behavior with states ranging from steady periodic and localized states to various time-periodic states. The latter include standing, traveling, and modulated waves corresponding to spatially periodic and localized traveling, wiggling, and alternating peak patterns and their combinations.

Published: July 2022

Abstract
In diffraction experiments, natural gratings often create uncommon diffraction patterns compared with those resulting from manufactured gratings. This study analyzed a unique diffraction pattern obtained by a grating from a flying termite wing. A ring-like diffraction pattern was formed because of the grating morphology from a flying termite wing, which consisted of horizontal- and vertical-structured slits. The mechanism of diffraction pattern formation is also provided. The distance between slits was measured using digital microscope images and a diffraction experiment, with the results coming to an agreement. Using this grating in a diffraction experiment can help educators provide an alternative diffraction experiment that supports students in studying the topic in a more complex manner.
Neumann and Dirichlet boundary conditions for the one-dimensional wave equation
Authors: Williams Hollis 
Published: July 2022

Abstract
The notion of a boundary condition is typically considered to be somewhat advanced and not suitable to be introduced in high school level physics. In this article, we give a simple visual demonstration of the difference between Dirichlet and Neumann boundary conditions for a string which oscillates according to the one-dimensional wave equation. The classical Dirichlet problem for a vibrating string in the plane is mathematically deep, but we will avoid the mathematical issues here and only focus on some key physical points which are relevant for understanding how waves propagate along strings.

Abstract

Objective. To assess the performance and added value of processing complete digital endoscopic video sequences for the automatic recognition of stone morphological features during a standard-of-care intra-operative session.Approach. A computer-aided video classifier was developed to predict in-situ the morphology of stone using an intra-operative digital endoscopic video acquired in a clinical setting. Using dedicated artificial intelligence (AI) networks, the proposed pipeline selects adequate frames in steady sequences of the video, ensures the presence of (potentially fragmented) stones and predicts the stone morphologies on a frame-by-frame basis. The automatic endoscopic stone recognition (A-ESR) is subsequently carried out by mixing all collected morphological observations.Main results. The proposed technique was evaluated on pure (i.e. include one morphology) and mixed (i.e. include at least two morphologies) stones involving ‘Ia/Calcium Oxalate Monohydrate’ (COM), ‘IIb/Calcium Oxalate Dihydrate’ (COD) and ‘IIIb/Uric Acid’ (UA) morphologies. The gold standard ESR was provided by a trained endo-urologist and confirmed by microscopy and infra-red spectroscopy. For the AI-training, 585 static images were collected (349 and 236 observations of stone surface and section, respectively) and used. Using the proposed video classifier, 71 digital endoscopic videos were analyzed: 50 exhibited only one morphological type and 21 displayed two. Taken together, both pure and mixed stone types yielded a mean diagnostic performances as follows: balanced accuracy = [88 ± 6] (min = 81)%, sensitivity = [80 ± 13] (min = 69)%, specificity = [95 ± 2] (min = 92)%, precision = [78 ± 12] (min = 62)% and F1-score = [78 ± 7] (min = 69)%.Significance. These results demonstrate that AI applied on digital endoscopic video sequences is a promising tool for collecting morphological information during the time-course of the stone fragmentation process without resorting to any human intervention for stone delineation or the selection of adequate steady frames.

Published: July 2022

Abstract

Objective. Automated cell nuclei segmentation is vital for the histopathological diagnosis of cancer. However, nuclei segmentation from ‘hematoxylin and eosin’ (HE) stained ‘whole slide images’ (WSIs) remains a challenge due to noise-induced intensity variations and uneven staining. The goal of this paper is to propose a novel deep learning model for accurately segmenting the nuclei in HE-stained WSIs. Approach. We introduce FEEDNet, a novel encoder-decoder network that uses LSTM units and ‘feature enhancement blocks’ (FE-blocks). Our proposed FE-block avoids the loss of location information incurred by pooling layers by concatenating the downsampled version of the original image to preserve pixel intensities. FEEDNet uses an LSTM unit to capture multi-channel representations compactly. Secondly, for datasets that provide class information, we train a multiclass segmentation model, which generates masks corresponding to each class at the output. Using this information, we generate more accurate binary masks than that generated by conventional binary segmentation models. Main results. We have thoroughly evaluated FEEDNet on CoNSeP, Kumar, and CPM-17 datasets. FEEDNet achieves the best value of PQ (panoptic quality) on CoNSeP and CPM-17 datasets and the second best value of PQ on the Kumar dataset. The 32-bit floating-point version of FEEDNet has a model size of 64.90 MB. With INT8 quantization, the model size reduces to only 16.51 MB, with a negligible loss in predictive performance on Kumar and CPM-17 datasets and a minor loss on the CoNSeP dataset. Significance. Our proposed idea of generalized class-aware binary segmentation is shown to be accurate on a variety of datasets. FEEDNet has a smaller model size than the previous nuclei segmentation networks, which makes it suitable for execution on memory-constrained edge devices. The state-of-the-art predictive performance of FEEDNet makes it the most preferred network. The source code can be obtained from https://github.com/CandleLabAI/FEEDNet.
Performance evaluation of piezo sensors with respect to accelerometers for 3D modal analysis of structures
Authors: Aulakh Dattar Singh , Bhalla Suresh 
Published: July 2022

Abstract
Strain modal analysis, as a new domain in the health monitoring field, needs to be studied in depth for experimental modal testing. Towards this purpose, this paper experimentally investigates the efficacy of piezo sensors for structural identification for structural health monitoring under different excitations applicable to large-scale structures. The piezo sensors are evaluated against industry-standard accelerometers by experimental modal testing of a scaled-down model of a pedestrian foot over bridge. The model is excited under the impact hammer, electro-dynamic shaker-based sweep and random excitations, and pedestrian motion (PM)-based low-amplitude excitations. Piezo sensors are found to be capable of capturing the modal parameters (modal frequencies, damping ratios and mode shape vector) under all the excitations with excellent correlation with respect to accelerometer-based parameters. However, some modes are missed under the shaker and PM-based excitations compared to the impact hammer-based excitations for both accelerometers and piezo sensors. Modal parameters of lower modes are successfully extracted under low-level pedestrian excitations, the most efficient type of excitation acting in operational conditions. High modal assurance criteria values between the strain and the displacement mode shapes establish the piezo sensors as effective for strain-based vibration testing and structural identification.
