description: We present first heavenly equation of Plebański in a two-component evolutionary form and obtain Lagrangian and Hamiltonian representations of this system. We study all point symmetries of the two-component system and, using the inverse Noether theorem in the Hamiltonian form, obtain all the integrals of motion corresponding to each variational (Noether) symmetry. We derive two linearly independent recursion operators for symmetries of this system related by a discrete symmetry of both the two-component system and its symmetry condition. Acting by these operators on the first Hamiltonian operator $J_0$ we obtain second and third Hamiltonian operators. However, we were not able to find Hamiltonian densities corresponding to the latter two operators. Therefore, we construct two recursion operators, which are either even or odd, respectively, under the above-mentioned discrete symmetry. Acting with them on $J_0$, we generate another two Hamiltonian operators $J_+$ and $J_-$ and find the corresponding Hamiltonian densities, thus obtaining second and third Hamiltonian representations for the first heavenly equation in a two-component form. Using P. Olver's theory of the functional multi-vectors, we check that the linear combination of $J_0$, $J_+$ and $J_-$ with arbitrary constant coefficients satisfies Jacobi identities. Since their skew symmetry is obvious, these three operators are compatible Hamiltonian operators and hence we obtain a tri-Hamiltonian representation of the first heavenly equation. Our well-founded conjecture applied here is that P. Olver's method works fine for nonlocal operators and our proof of the Jacobi identities and bi-Hamiltonian structures crucially depends on the validity of this conjecture.
description: Some text overlap with our paper arXiv:1510.03666 is caused by our use here of basically the same method for discovering the Hamiltonian and bi-Hamiltonian structures of the equation, but the equation considered here and the results are totally different from arXiv:1510.03666

description: En 2016, la Haute Autorité de santé, l’Agence nationale pour l’amélioration des conditions de travail et la Direction générale de l’offre de soins mettent en place 12 « clusters sociaux qualité de vie au travail » (QVT) qui vont rassembler 79 établissements de santé volontaires. L’objectif est de les accompagner dans la mise en œuvre d’une démarche QVT afin de leur permettre de soutenir une articulation effective entre la qualité de vie au travail et la qualité des soins. La QVT a pour condition la capacité des salariés à s’exprimer et à agir sur le contenu de leur travail. Des séances de réflexion collectives sont organisées par groupes de représentants de 7 ou 8 établissements (durant lesquelles les participants se forment et échangent sur leurs avancées respectives), en alternance avec des journées « individuelles » sur site (au cours desquelles l’antenne régionale de l’Anact accompagne les professionnels dans la mise en œuvre de leur démarche). Une évaluation qualitative a été menée en 2017 auprès de 10 établissements. L’objectif était de comprendre comment les acteurs avaient trouvé les moyens d’assurer la continuité d’une démarche QVT, de la mise en place du trinôme participant aux clusters jusqu’à l’action effective sur le contenu du travail. Au vu de l’exemple d’une démarche QVT dans un centre hospitalier et de l’évaluation des 10 cas, 3 leviers nous semblent importants pour lier qualité de vie au travail et qualité du travail : le dépassement des conflits interpersonnels ou hiérarchiques, la définition d’un problème commun intéressant les acteurs et l’engagement de la direction.

A 750 GeV graviton from holographic composite dark sectors

description: We show that the 750 GeV di-photon excess can be interpreted as a spin-2 resonance arising from a strongly interacting dark sector featuring some departure from conformality. This spin-2 resonance has negligible couplings to the SM particles, with the exception of the SM gauge bosons which mediate between the two sectors. We have explicitly studied the collider constraints as well as some theoretical bounds in a holographic five dimensional model with a warp factor that deviates from AdS$_5$. In particular, we have shown that it is not possible to decouple the vector resonances arising from the strong sector while explaining the di-photon anomaly and keeping the five dimensional gravity theory under perturbative control. However, vector resonances with masses around the TeV scale can be present while all experimental constraints are met.

description: We present a universal characterization scheme for chimera states applicable to both numerical and experimental data sets. The scheme is based on two correlation measures that enable a meaningful definition of chimera states as well as their classification into three categories: stationary, turbulent and breathing. In addition, these categories can be further subdivided according to the time-stationarity of these two measures. We demonstrate that this approach both is consistent with previously recognized chimera states and enables us to classify states as chimeras which have not been categorized as such before. Furthermore, the scheme allows for a qualitative and quantitative comparison of experimental chimeras with chimeras obtained through numerical simulations.

description: Genitourinary syndrome of menopause (GSM) is a new term for a condition more renowned as atrophic vaginitis. It is used to describe a variety of menopausal symptoms and signs that are related to the physical changes of the vulva, vagina and lower urinary tract. The etiology of GSM is secondary to decreased levels of endogenous estrogens and represents a common but underreported condition. Currently Intra-Vaginal application of oestrogen has been considered an effective treatment of atrophic vaginitis.Recently, PRP has becoming popular as a non-operative treatment option for GSM symptoms.Our study focuses on the use platelet rich plasma for the treatment of GSM as it has natural mechanisms of cell regeneration and requires less frequent dosing and have better compliance when compared to estrogen creams. Purpose of the study is to compare the effectiveness of intra vaginal estrogen cream with intravaginal PRP in treatment of GSM.

description: We investigate the magnetization processes of a standard Ginzburg-Landau model for chiral p-wave superconducting states in an applied magnetic field. We find that the phase diagram is dominated by triangular lattices of doubly quantized vortices. Only in close vicinity to the upper critical field, the lattice starts to dissociate into a structure of single-quanta vortices. The degeneracy between states with opposite chirality is broken in a nonzero field. If the magnetization starts with an energetically unfavorable chirality, the process of chirality-inversion induced by the external magnetic field results in the formation of a sequence of metastable states with characteristic magnetic signatures that can be probed by standard experimental techniques.

description: The value of psychological well-being is an important post-pandemic discourse of covid-19. The impact of this pandemic caused the psychological well-being index of Malaysians at a moderate level with an overall score of 7.2. In this regard, various initiatives at the global level to control the sustainability of psychological well-being through psychospiritual approaches are actively pursued by various parties. Among them are Mindfulness Meditation, Ayurveda, Yoga and other non-Muslim psychospiritual approaches. Thus, the purpose of this study is to analyse the concept of psychospiritual in the Qur'an as a control mechanism for psychological well-being. Based on a qualitative method with a thematic content analysis approach, this study found that the concept of psychospiritual in the Quran is holistic. The concepts of iṭmi’nān al-qulūb (peace of mind) and al-Sakīnah (tranquillity) which are discussed twenty times in the Qur’an are part of the core underlying the Qur’an-based psychospiritual approach. A combination of understanding about it is found to be able to control and stabilise the mind or emotions. In conclusion, the concept of psychospiritual in the Qur’an is significant and deserves to be dignified as part of the complementary mechanism of psychological well-being control.

description: Observations of exoplanet atmospheres have revealed the presence of cloud particles in their atmospheres. 3D modelling of cloud formation in atmospheres of extrasolar planets coupled to the atmospheric dynamics has long been a challenge. We investigate the thermo-hydrodynamic properties of cloud formation processes in the atmospheres of hot Jupiter exoplanets. We simulate the dynamic atmosphere of HD 189733b with a 3D model that couples 3D radiative-hydrodynamics with a kinetic, microphysical mineral cloud formation module designed for RHD/GCM exoplanet atmosphere simulations. Our simulation includes the feedback effects of cloud advection and settling, gas phase element advection and depletion/replenishment and the radiative effects of cloud opacity. We model the cloud particles as a mix of mineral materials which change in size and composition as they travel through atmospheric thermo-chemical environments. All local cloud properties such as number density, grain size and material composition are time-dependently calculated. Gas phase element depletion as a result of cloud formation is included in the model. In-situ \textit{effective medium theory} and Mie theory is applied to calculate the wavelength dependent opacity of the cloud component. We present a 3D cloud structure of a chemically complex, gaseous atmosphere of the hot Jupiter HD 189733b. Mean cloud particle sizes are typically sub-micron (0.01-0.5 $μ$m) at pressures less than 1 bar with hotter equatorial regions containing the smallest grains. Denser cloud structures occur near terminator regions and deeper ($\sim$ 1 bar) atmospheric layers. Silicate materials such as MgSiO$_{3}$[s] are found to be abundant at mid-high latitudes, while TiO$_{2}$[s] and SiO$_{2}$[s] dominate the equatorial regions.

description: Angular momentum distribution and its redistribution are of crucial importance in formation and evolution of circumstellar disks. Many molecular line observations toward young stellar objects indicate that radial distributions of the specific angular momentum $j$ are more or less universal. In small scales, typically $R\lesssim$ 100 AU, the specific angular momenta distribute like $j\propto r^{1/2}$, indicating existence of rotationally supported disk. In outer regions, $R\gtrsim$ 5000 AU, $j$ increases as the radius increases and the slope is steeper than unity, which is supposed to reflect the original angular momentum distributions in the maternal molecular clouds. And lastly there is a connecting region, 100 AU $\lesssim R \lesssim$ 5000 AU, in which $j$-distribution looks almost flat. While this is often interpreted as a consequence of conservation of the specific angular momentum, it actually is insufficient and requires a stronger condition that the initial distribution of $j$ must be spatially uniform. However, this requirement is unrealistic and inconsistent with observations. In this work, we propose a simple alternative explanation; the flat $j$ profile is produced by strong prolongation due to the large velocity gradient in the accreting flow no matter what the initial $j$ distribution is. We provide a simple analytic model for gravitational collapse of molecular clouds. This model can be used to estimate ages of protostars based solely on the observed rotation profile. We demonstrate its validity in comparison with hydrodynamic simulations, and apply the model to young stellar objects such as L1527 IRS, TMC-1A and B335.

description: Contexte et objectif. En 2015, lors de la visite de certification au centre hospitalier de Valenciennes, la Haute Autorité de santé a émis une recommandation sur la thématique du management de la prise en charge du patient en endoscopie, car l’activité d’endoscopie est répartie entre plusieurs zones géographiques et concerne plusieurs spécialités sans approche transversale homogène. Il a donc été nécessaire de développer une organisation institutionnelle pluridisciplinaire pour mettre en œuvre une politique qualité et sécurité dédiée. Méthode. Un groupe de travail composé d’experts et de professionnels de terrain s’est réuni trimestriellement. Un plan d’actions, basé sur la déclinaison opérationnelle de la politique de l’établissement selon le principe du Plan, Do, Check, Act (planifier, faire, vérifier, agir), a été défini. Il inclut formation, formalisation des circuits, mise en place d’une gestion documentaire associée, évaluation des processus, définition et suivi d’indicateurs, analyse des évènements indésirables associés aux soins… Résultats. Après 4 ans d’existence, le groupe « endoscopie » est connu et reconnu institutionnellement, car les travaux menés sont réalistes et effectifs. En effet, l’expérience a permis de développer une organisation apprenante au bénéfice de la qualité et de la sécurité de la prise en charge, avec un tableau de responsabilité de chaque acteur de processus validé, une gestion électronique des documents dédiée, une formation reconnue dans le dispositif de développement professionnel continu… Et les résultats ont été exemplaires puisque les différents audits observationnels des processus montrent un progrès marqué d’année en année, 100% des professionnels sont habilités et le tableau de bord d’indicateurs est géré et analysé. La maturité du projet ne fait plus débat. Conclusion. Ce projet a atteint son deuxième cycle de vie, avec de nouveaux axes de progression. La prochaine évolution est la transposition de ce schéma de travail à notre groupement hospitalier d’appartenance, composé de 12 établissements.

description: We propose a function-based temporal pooling method that captures the latent structure of the video sequence data - e.g. how frame-level features evolve over time in a video. We show how the parameters of a function that has been fit to the video data can serve as a robust new video representation. As a specific example, we learn a pooling function via ranking machines. By learning to rank the frame-level features of a video in chronological order, we obtain a new representation that captures the video-wide temporal dynamics of a video, suitable for action recognition. Other than ranking functions, we explore different parametric models that could also explain the temporal changes in videos. The proposed functional pooling methods, and rank pooling in particular, is easy to interpret and implement, fast to compute and effective in recognizing a wide variety of actions. We evaluate our method on various benchmarks for generic action, fine-grained action and gesture recognition. Results show that rank pooling brings an absolute improvement of 7-10 average pooling baseline. At the same time, rank pooling is compatible with and complementary to several appearance and local motion based methods and features, such as improved trajectories and deep learning features.

description: With this thesis we try to highlight the human body as a protagonist in the work of Anna Komnene Alexiad. More specifically, we will deal with all those incidents where the human body occupied the first place in the narration of the events. The harsh conditions of war and long-term tensions created problems for humans, causing injuries and illnesses. At the same time, at this point we are also concerned with the course of medical science during the 12th century and how Anna Komnene could have access to medical knowledge and education. Her love for the members of her family and admiration for the protagonists of the events led her to many descriptions of them, starting from their external features, with an emphasis on the physique of the protagonists and ending with the description of the character and personality, as she was particularly interested in the man behind the warriors. Finally, the scenes in which emotions are externalized with the movements of the body, face and gestures were highlighted, thus making the body the protagonist of the story

In this article, an experiment is designed to measure the lifetime of o-Ps, giving a result of 3.1 ns. A PSD parameter based on photon emission time distribution (PETD) was constructed to discriminate e$^+$/e$^-$. Finally, the application of e$^+$/e$^-$ discrimination in the JUNO experiment is shown. It helps suppress $^{8}$He/$^{9}$Li backgrounds and improves the sensitivity by 0.6 in $χ^2$ analysis with an assumption of $σ$=1 ns PMT Transit Time Spread, which will bring a smearing effect to the PETD.

description: For the performance and stability of liquid propellant rocket engines, injector behavior is of utmost importance. A major problem is achieving an effective chemical reaction and a highly efficient homogeneous mixture of fuels with a minimum chamber length. These processes are also crucial in many other modern combustion systems such as chemical industrial plants, heating systems, and engines, which lead to extremely high requirements for the injection equipment. This article presents a concept for an injection system based on the application of different porous materials and oxidizer injectors. The system has been designed based on DLR Lampoldshausen\'s heritage within porous injection technologies and its possible future use at the DLR LUMEN Technology Demonstrator. The setup has been successfully implemented and operated under sub-to-supercritical pressure conditions (tested from 35 to 65 bar), with respect to the critical pressure of oxygen, using the penta-injector research combustor. Optical investigations of the nearinjector combustion and flow field behavior for different penta-injector elements were conducted. Fuel was injected through a metallic mesh (Rigimesh) or sinter bronze (CA-100). As for the oxygen injector, three different variations were tested: a conventional axial injector, a pentagon pattern riffling injector, and a helical swirl injector. The latter two were manufactured using Additive Layering Manufacturing (ALM).

description: We derive analytic formula for electric and magnetic fields produced by a moving charged particle in a conducting medium with the electric conductivity $σ$ and the chiral magnetic conductivity $σ_χ$. We use the Green function method and assume that $σ_χ$ is much smaller than $σ$. The compact algebraic expressions for electric and magnetic fields without any integrals are obtained. They recover the Lienard-Wiechert formula at vanishing conductivities. Exact numerical solutions are also found for any values of $σ$ and $σ_χ$ and are compared to analytic results. Both numerical and analytic results agree very well for the scale of high energy heavy ion collisions. The space-time profiles of electromagnetic fields in non-central Au+Au collisions have been calculated based on these analytic formula as well as exact numerical solutions.

description: We study the statistics of increments in record values in a time series $\{x_0=0,x_1, x_2, \ldots, x_n\}$ generated by the positions of a random walk (discrete time, continuous space) of duration $n$ steps. For arbitrary jump length distribution, including Lévy flights, we show that the distribution of the record increment becomes stationary, i.e., independent of $n$ for large $n$, and compute it explicitly for a wide class of jump distributions. In addition, we compute exactly the probability $Q(n)$ that the record increments decrease monotonically up to step $n$. Remarkably, $Q(n)$ is universal (i..e., independent of the jump distribution) for each $n$, decaying as $Q(n) \sim {\cal A}/\sqrt{n}$ for large $n$, with a universal amplitude ${\cal A} = e/\sqrtπ = 1.53362\ldots$.

description: The performance and stability of liquid rocket engines heavily rely on the behavior of the injector. Achieving an effective chemical reaction and highly efficient homogeneous fuel mixture within a minimal chamber length is a major challenge. This requirement extends to various modem combustion systems such as chemical industrial plants, heating systems, and engines, placing extreme demands on injection equipment. This article presents a concept for a Swirler injector for the oxidizer that utilizes helical swirlers with different angles, lengths, and positions within the injector. The design of this system draws on the DLR Lampoldshausen\'s expertise in porous injection technologies, with potential future applications in the DLR LUMEN Technology Demonstrator. To evaluate the performance of the system, tests were conducted at the Water Test Laboratory at DLR Lampoldshausen using water as a simulation of liquid oxygen (LOX) behavior at various pressures (ranging from Oto 20 bar). High-speed cameras (Chronos CR21-l.0-16C) were employed for shadowgraphy imaging to visualize the spray angle at the injector post orifice and study atomization. Pressure measurements were taken using static pressure sensors at the LOX-Dome and directly before the swirler to assess the influence of pressure loss caused by the swirler in relation to the raw surface condition of the 3D-printed injector. The helical swirlers were differentiated based on the swirler angle (15, 30, and 45 degrees), swirler length (full tum/ 360 degrees or half tum/ 180 degrees), and swirler position (entry, middle, and exit) within the injector.

description: Traditional hybrid rocket fuel can improve fuel combustion efficiency through structural design which is conducive to aerodynamic enhancement of regression rate. However, complex structure increases the difficulty of fuel structure forming, hindering the scientific research and engineering application verification of fuel charge with heterogeneous and topological structure in the hybrid rocket. 3D printing is used to manufacture hybrid rocket fuel grains with a special mesh structure to improve combustion performance. \\\\!hen analyzing the gas-phase and solid-phase combustion characteristics of acrylonitrilebutadiene-styrene (ABS) fuel with a single-hole mesh structure, the penetrative combustion phenomenon of 3D printed structural fuel was first discovered, and the minimum print infill density of fuel charge axisymmetric ring disintegration caused by penetrative combustion was determined. The results show that penetrative combustion can effectively increase the regression rate.
