title: Le shadowing pour recueillir le vécu des usagers et améliorer la qualité des soins : une expérimentation régionale
Creators: name: Van Straaten, Perrine
Publisher: name: Health & Co
Year: 2019

description: L’expérience des patients est aujourd’hui reconnue comme une dimension de la qualité des soins. Sa définition proposée par le Picker Institute est claire et acceptée. Malgré cette reconnaissance, le recueil de l’expérience des patients en France est très limité et présent essentiellement à travers le questionnaire e-Satis de la Haute Autorité de santé, adressé aux patients ayant séjourné plus de 48h dans un établissement de santé MCO. Ce questionnaire a pour objectif principal le recueil de la satisfaction des patients et dans une moindre mesure de leur expérience. Le shadowing, est une méthode de recueil de l’expérience des patients en temps réel afin d’identifier les actions qui permettent d’améliorer le vécu des patients sur un parcours donné. L’objectif de ce travail était d’évaluer la faisabilité et l’intérêt du shadowing dans des établissements volontaires sanitaires et en Ehpad de la région Auvergne Rhône Alpes. Cette expérimentation a été conduite dans 15 établissements sanitaires et 6 Ehpad. Elle a démontré la faisabilité et l’intérêt du shadowing dans de nombreuses spécialités, en ambulatoire aussi bien qu’en court et long séjour en secteur sanitaire ainsi qu’Ehpad. Les intérêts principaux du shadowing étaient l’implication des patients/résidents en tant que partenaire des soignants pour l’amélioration de la qualité des soins, la prise de conscience par les soignants de la perspective patient/résident et l’identification d’actions concrètes pour améliorer l’expérience de nombreux patients. L’expérimentation a fait émerger le besoin de disposer d’une méthodologie simple et claire. Ainsi le Ceppraal a rédigé un guide et un kit-outil de la méthode « Amppati » (Amélioration du parcours vécu par le patient et son entourage) disponibles en accès libre sur le site internet du Ceppraal.

description: Diffuse and translucent molecular clouds fill a vast majority of the interstellar space in the galactic disk being thus the most typical objects of the Interstellar Medium (ISM). Recent advances in observational techniques of modern optical and ultraviolet spectroscopy led to detection of many features of atomic and molecular origin in spectra of such clouds. Molecular spectra of heteronuclear diatomic molecules, ie. OH, OH+, CH CH+, CN, NH, CO play an important role in understanding chemistry and physical conditions in environments they do populate. A historical review of astronomical observations of interstellar molecules is presented. Recent results based on visual and ultraviolet observations of molecular features in spectra of reddened, early type OB-stars are presented and discussed. Appearance of vibrational-rotational spectra with observed transitions based on high-quality spectra, are also presented. Relations between column densities of heteronuclear diatomics (based on the recommended oscillator strengths) and intensities of diffuse interstellar bands (DIBs) are also presented and discussed.

description: Objectif. Les indicateurs liés aux escarres sont considérés comme particulièrement pertinents pour évaluer la qualité des soins hospitaliers. Cependant, nous avons trouvé quelques exemples dans la littérature sur la manière dont ces indicateurs pouvaient être suivis et utilisés au niveau d’un hôpital. Cette étude présente les résultats de notre enquête sur la prévalence institutionnelle des escarres ainsi que la façon dont ces résultats ont été utilisés pour orienter nos actions d’amélioration de la qualité. Conception de l’étude, contexte et participants. Cette enquête transversale menée dans notre institution entre juin et septembre 2014 a recueilli ses données dans les dossiers des patients et par observation directe. Ont été inclus tous les patients hospitalisés présents un jour donné dans les services de médecine, chirurgie, psychiatrie, rééducation, urgences et soins intensifs. Mesures principales du résultat. La prévalence des escarres et le degré d’observance pour les surfaces de soutien ont été estimés pour tout l’hôpital et pour chaque service. Résultats. En tout, 1 353 patients hospitalisés dans 37 services ont été inclus dans notre analyse. Le taux global était de 5,5% (IC95[4,3-6,8]) pour la prévalence brute des escarres acquises à l’hôpital et de 89% (IC95[87,6-90,9]) pour l’observance en matière de surfaces de soutien. Les courbes en entonnoir ont montré l’hétérogénéité de ces mesures dans les services hospitaliers. Parmi les 37 services, trois avaient un taux de prévalence standardisé supérieur à la valeur moyenne +2 écarts-types (ET) et cinq avaient des taux d’observance inférieurs à la valeur moyenne -2 ET. Conclusion. L’identification d’une hétérogénéité au niveau des services en matière de prévalence d’escarres et d’observance des surfaces de soutien peut alors être utilisée pour orienter les actions locales d’amélioration de la qualité.

description: We determine numerically the single-particle and the two-particle spectrum of the three-state quantum Potts model on a lattice by using the density matrix renormalization group method, and extract information on the asymptotic (small momentum) S-matrix of the quasiparticles. The low energy part of the finite size spectrum can be understood in terms of a simple effective model introduced in a previous work, and is consistent with an asymptotic S-matrix of an exchange form below a momentum scale p*. This scale appears to vanish faster than the Compton scale, mc, as one approaches the critical point, suggesting that a dangerously irrelevant operator may be responsible for the behaviour observed on the lattice.
title: Analyse des risques liés à la prescription : que nous apprennent les interventions pharmaceutiques ?
Creators: name: Malki, Myriam
Publisher: name: Health & Co
Year: 2019

description: L’étape de la prescription médicale est rarement prise en compte dans les analyses de risques. Peut-être du fait d’une moindre sensibilisation des médecins, mais probablement aussi du fait de l’analyse pharmaceutique. En effet les problèmes détectés lors de cette analyse ne sont pas déclarés par exemple en évènements indésirables, et apparaissent donc peu dans les bilans classiques de gestion des risques. L’objectif de ce travail est de réaliser une analyse de risque lors de la prescription à partir des interventions pharmaceutiques (IP), et d’évaluer leur efficacité sur ces risques potentiels. Matériels et méthodes : un groupe de travail composé de médecins, de pharmaciens et d’internes, d’un préparateur et d’un ingénieur qualité a été constitué dans notre établissement comportant des services de santé mentale et de neurosciences. Du 13/06/2016 au 24/07/2016, les IP ont été relevées et analysées par le groupe de travail. Des actions préventives et correctrices ont été proposées. Résultats : 43 scénarios dangereux ont été identifiés : 10 de criticité 3, 21 de criticité 2 et 12 de criticité 1. La validation pharmaceutique permet une diminution de 50% du nombre de scénarios de criticité inacceptable. Les principales actions proposées par le groupe de travail sont : une sensibilisation des prescripteurs sur les risques de torsades de pointe liés à des médicaments ciblés pour l’établissement, une sensibilisation sur les risques de diminution du seuil épileptogène, sur l’importance de la relecture de leur prescription pour détecter notamment les erreurs d’unités, et le rappel sur des méthodes de prescriptions dans le logiciel. Discussion-Conclusion : ce travail a permis une première évaluation des risques potentiels liés à la prescription. Il sera à renforcer par l’inclusion d’autres éléments que les IP (conditions de travail, connaissances des médecins…) pour élargir l’analyse et proposer de nouvelles actions.

description: We discuss decoherence in discrete-time quantum walks in terms of a phenomenological model that distinguishes spin and spatial decoherence. We identify the dominating mechanisms that affect quantum-walk experiments realized with neutral atoms walking in an optical lattice. From the measured spatial distributions, we determine with good precision the amount of decoherence per step, which provides a quantitative indication of the quality of our quantum walks. In particular, we find that spin decoherence is the main mechanism responsible for the loss of coherence in our experiment. We also find that the sole observation of ballistic-instead of diffusive-expansion in position space is not a good indicator of the range of coherent delocalization. We provide further physical insight by distinguishing the effects of short- and long-time spin dephasing mechanisms. We introduce the concept of coherence length in the discrete-time quantum walk, which quantifies the range of spatial coherences. Unexpectedly, we find that quasi-stationary dephasing does not modify the local properties of the quantum walk, but instead affects spatial coherences. For a visual representation of decoherence phenomena in phase space, we have developed a formalism based on a discrete analogue of the Wigner function. We show that the effects of spin and spatial decoherence differ dramatically in momentum space.

description: The goals throughout aviation history were/are: 1.) Further / Faster / Higher. 2.) Improved Economics. 3.) Sustainability.

Aviation is growing quity steadily with 5 % per year, but self-set goals by various aviation organizations to limit carbon emissions are unlikely to be met (in 2020, in 2050, ...) and carbon offset schemes will not be fully in place in 2020.

Carbon offset schemes only make limited sense and are debatable.

Unconventional aircraft configurations (here: BWA, BWB) do not show an overall benefit and will not be a solutions to aviation‘s future.

Conventional configurations questioning established design rules and requirements show much potential!

It is important to come early to a conclusion about which aviation fuels should be used together (not just one) to meet demand. Candidates are: a) remaining fossile kerosene, b) hydrogen, c) drop in fuel from Power-to-Liquid.

Undersøgelsen viste, at ca. 11 procent af de planlagte timer i folkeskolen afholdes af en vikar. Størstedelen af disse vikartimer dækkes af en vikar uden en kvalifikationsgivende uddannelse.
Undervisningsministeriet, KL og Skolelederforeningen har bedt VIVE om at perspektivere denne undersøgelse ved at kigge på:
1.Hvordan vikarundervisning kan defineres
2.Hvordan skolerne og kommunerne registrerer og følger op på underviserfravær og brugen af vikarer
3.Årsagerne til underviserfravær, og hvordan skolerne dækker fraværet med vikarer
4.Skolernes og kommunernes forudsætninger for og positive erfaringer med vikardækning.
VIVE har undersøgt årsagerne til lærerfravær, hvem og hvordan lærernes timer dækkes i deres fravær, og hvordan lærerfravær og brugen af vikarer defineres og registreres.

description: This paper reports very-long-baseline interferometry observations of the radio-loud broad absorption line (BAL) quasar J1020+4320 at 1.7, 2.3, 6.7, and 8.4 GHz using the Japanese VLBI network (JVN) and European VLBI network (EVN). The radio morphology is compact with a size of ~10 pc. The convex radio spectrum is stable over the last decade; an observed peak frequency of 3.2 GHz is equivalent to 9.5 GHz in the rest frame, suggesting an age of the order of ~100 years as a radio source, according to an observed correlation between linear size and peak frequency of compact steep spectrum (CSS) and giga-hertz peaked spectrum (GPS) radio sources. A low-frequency radio excess suggests relic of past jet activity. J1020+4320 may be one of the quasars with recurrent and short-lived jet activity during a BAL-outflowing phase.

description: Sparsity has been recently introduced in cosmology for weak-lensing and CMB data analysis for different applications such as denoising, component separation or inpainting (i.e. filling the missing data or the mask). Although it gives very nice numerical results, CMB sparse inpainting has been severely criticized by top researchers in cosmology, based on arguments derived from a Bayesian perspective. Trying to understand their point of view, we realize that interpreting a regularization penalty term as a prior in a Bayesian framework can lead to erroneous conclusions. This paper is by no means against the Bayesian approach, which has proven to be very useful for many applications, but warns about a Bayesian-only interpretation in data analysis, which can be misleading in some cases.

description: We verify that SU(N)_{{}_{TC}}\otimes SU(3)_{{}_{L}}\otimes U(1)_{{}_{X}} models, where the gauge symmetry breaking is totally dynamical and promoted by the non-Abelian technicolor (TC) group and the strong Abelian interactions, are quite constrained by the LHC data. The theory contains a T quark self-energy involving the mixing between the neutral gauge bosons, which introduces the coupling between the light and heavy composite scalar bosons of the model. We determine the lightest scalar boson mass for these models from an effective action for composite operators, assuming details about the dynamics of the strong interaction theories. Comparing the value of this mass with the ATLAS and CMS observation of a new boson with a mass M_ϕ \sim 125GeV and considering the lower bound determined by the LHC Collaborations on the heavy neutral gauge boson (Z^\prime) present in these models, we can establish constraints on the possible models. For example, if SU(N)_{{}_{TC}}\equiv SU(2)_{{}_{TC}}, with technifermions in the fundamental representation, the model barely survives the confrontation with the LHC data.

description: We examine the electron-ion streaming instabilities driven by drift velocities of the order of the electron thermal velocity in a nonmagnetized plasma by one-dimensional electrostatic particle-in-cell code which adopts an ion-to-electron mass ratio of 1600. An initial state is set up where the ion bulk speed is zero while the electrons drift relative to ions, and where electrons are much hotter. We examine in detail four runs where drift velocity is systematically varied from lower than to larger than the electron thermal velocity. In all runs the Langmuir waves with Doppler-shifted frequencies dominate early on when streaming instabilities are too weak to discern. And then intense ion-acoustic waves or Buneman instabilities appear, which tend to be accompanied by localized electron and ion beams. Ion-acoustic modes and Buneman modes co-exist in the system when the initial drift velocity is just over the electron thermal speed. Beam modes are excited when the localized beams with large enough velocities appear. In the developed stage of instabilities, the direction in which density depressions propagate is always opposite to that of the localized ion beams. When the initial drift velocity is close to the electron thermal speed, categorizing the relevant instabilities is not easy, and one needs to examine in detail the wave dispersion diagrams at various stages of the evolution of the system.

description: Medical clinical studies about paired body parts often involve stratified bilateral data. The correlation between responses from paired parts should be taken into account to avoid biased or misleading results. This paper aims to test if the relative risk ratios across strata are equal under the optimal algorithms. Based on different algorithms, we obtain the desired global and constrained maximum likelihood estimations (MLEs). Three asymptotic test statistics (i.e. TL, TSC and TW) are proposed. Monte Carlo simulations are conducted to evaluate the performance of these algorithms with respect to mean square errors of MLEs and convergence rate. The empirical results show Fisher scoring algorithm is usually better than other methods since it has effective convergence rate for global MLEs, and makes mean-square error lower for constrained MLEs. Three test statistics are compared in terms of type I error rate (TIE) and power. Among these statistics, TSC is recommended according to its robust TIEs and satisfactory power.

description: We report on the spin properties of bright polariton solitons supported by an external pump to compensate losses. We observe robust circularly polarised solitons when a circularly polarised pump is applied, a result attributed to phase synchronisation between nondegenerate TE and TM polarised polariton modes at high momenta. For the case of a linearly polarised pump either s+ or s- circularly polarised bright solitons can be switched on in a controlled way by a s+ or s- writing beam respectively. This feature arises directly from the widely differing interaction strengths between co- and cross-circularly polarised polaritons. In the case of orthogonally linearly polarised pump and writing beams, the soliton emission on average is found to be unpolarised, suggesting strong spatial evolution of the soliton polarisation, a conclusion supported by polarisation correlation measurements. The observed results are in agreement with theory, which predicts stable circularly polarised solitons and unstable linearly polarised solitons resulting in spatial evolution of their polarisation.

description: A study of mu-tau conversion via the deep inelastic scattering process μN -> τX, with N a nucleon, is performed taking into account the effects from both spin-0 and spin-1 unparticles with lepton flavor violating (LFV) couplings. This process has attracted attention in the past as it may be at the reach of a future neutrino or muon factory. For the model parameters, we use the most recent constraints on the unparticle LFV couplings from the experimental limits on the muon anomalous magnetic moment and the LFV decay τ-> 3μ, whereas for the unparticle scale Λ_U and scale dimension d_U we use the bounds obtained from the search for mono-jets plus missing transverse energy at the LHC. The μN -> τX cross section is analyzed when the target is a proton and it is found that the unparticle effects can be larger than the contribution from Higgs exchange in the minimal supersymmetric standard model. We also analyze the behavior of the angular and energy distributions of the emitted tau lepton, which could be used to disentangle among distinct new physics contributions. It is found that, for a beam with an intensity of 10^20 muons with an energy around 50 GeV on a 10^2 gr/cm^2 mass target annually, there would be about 10^2-10^3 μN -> τX events per year. The potential background is discussed briefly.

description: We investigate both experimentally and theoretically disorder-induced damping of Bloch oscillations of Bose-Einstein condensates in optical lattices. The spatially inhomogeneous force responsible for the damping is realized by a combination of a disordered optical and a magnetic gradient potential. We show that the inhomogeneity of this force results in a broadening of the quasimomentum spectrum, which in turn causes damping of the centre-of-mass oscillation. We quantitatively compare the obtained damping rates to the simulations using the Gross-Pitaevskii equation. Our results are relevant for high precision experiments on very small forces, which require the observation of a large number of oscillation cycles.

description: We present de Haas-van Alphen (dHvA) measurements on high-mobility two-dimensional electron systems formed in modulation-doped SiSiGe (100) quantum wells and demonstrate directly the manifestation of the valley splitting in the magnetization. We resolve sawtoothlike magnetization oscillations at even filling factors which reflect the Landau quantization and the spin splitting of Landau levels in the electronic energy spectrum. At odd filling factors we observe the lifting of the valley degeneracy in Si at high magnetic field. The magnetization is a thermodynamic quantity that at low temperature reflects the ground-state energy of the interacting electron system. We can thus determine quantitatively the energetic splitting of the two occupied conduction-band valleys directly from the oscillation amplitude. Both valley and spin splitting are found to be enhanced by electron-electron interactions. The energy gap due to valley splitting is found to be ≥0.8meV at high perpendicular field B. From studies in tilted magnetic fields we find that the valley splitting is governed solely by B. From the spin splitting we recalculate an enhanced g factor g*=2.9 at ν=2 including the influence of disorder. This is significantly larger than the band-structure g factor of 2 in Si. We have successfully applied the coincidence technique for the dHvA effect and thus obtained a complementary means to determine the g factor. It yields a constant value g*≅3.2 for filling factors ν≥10. A detailed analysis of the magnetization traces enabled us also to determine quantitatively the residual level broadening Γ in this high-mobility SiSiGe system. We obtain a small value of Γ=0.15meV×B[T]12 for the SiSiGe heterostructure of 200000cm2(Vs) mobility at 0.3K. © 2005 The American Physical Society.

description: Pearson's chi-squared test is widely used to test the goodness of fit between categorical data and a given discrete distribution function. When the number of sets of the categorical data, say k, is a fixed integer, Pearson's chi-squared test statistic converges in distribution to a chi-squared distribution with k−1 degrees of freedom when the sample size n goes to infinity. In real applications, the number k often changes with n and may be even much larger than n. By using the martingale techniques, we prove that Pearson's chi-squared test statistic converges to the normal under quite general conditions. We also propose a new test statistic which is more powerful than chi-squared test statistic based on our simulation study. A real application to lottery data is provided to illustrate our methodology.

description: We investigate de Sitter solutions of N= 1 supergravity with an F-term scalar potential near a no-scale Minkowski point, as they may in particular arise from flux compactifications in string theory. We show that a large class of such solutions has a universal tachyon with η≤−43 at positive vacuum energies, thus forbidding meta-stable de Sitter vacua and slow-roll inflation. The tachyon aligns with the sgoldstino in the Minkowski limit, whereas the sgoldstino itself is generically stable in the de Sitter vacuum due to mass mixing effects. We specify necessary conditions for the superpotential and the Kähler potential to avoid the instability. Our result may also help to explain why the program of classical de Sitter hunting has remained unsuccessful, while constructions involving instantons or non-geometric fluxes have led to various examples of meta-stable de Sitter vacua.

description: Estimating the optimal treatment regime based on individual patient characteristics has been a topic of discussion in many forums. Advanced computational power has added momentum to this discussion over the last two decades and practitioners have been advocating the use of new methods in determining the best treatment. Treatments that are geared toward the ‘best’ outcome for a patient based on his/her genetic markers and characteristics are of high importance. In this article, we develop an approach to predict the optimal personalized treatment based on observational data. We have used inverse probability of treatment weighted machine learning methods to obtain score functions to predict the optimal treatment. Extensive simulation studies showed that our proposed method has desirable performance in selecting the optimal treatment. We provided a case study to examine the Statin use on cognitive function to illustrate the use of our proposed method.

description: We present a highly stable bow-tie power enhancement cavity for critical second harmonic generation (SHG) into the UV using a Brewster-cut β-BaB2O4 (BBO) nonlinear crystal. The cavity geometry is suitable for all UV wavelengths reachable with BBO and can be modified to accommodate anti-reflection coated crystals, extending its applicability to the entire wavelength range accessible with non-linear frequency conversion. The cavity is length-stabilized using a fast general purpose digital PI controller based on the open source STEMlab 125-14 (formerly Red Pitaya) system acting on a mirror mounted on a fast piezo actuator. We observe 130 h uninterrupted operation without decay in output power at 313 nm. The robustness of the system has been confirmed by exposing it to accelerations of up to 1 g with less than 10% in-lock output power variations. Furthermore, the cavity can withstand 30 min of acceleration exposure at a level of 3 grms without substantial change in the SHG output power, demonstrating that the design is suitable for transportable setups. © 2018 Author(s).

description: We obtain a nonsmooth extension of Noether's symmetry theorem for variational problems with delayed arguments. The result is proved to be valid in the class of Lipschitz functions, as long as the delayed Euler-Lagrange extremals are restricted to those that satisfy the DuBois-Reymond necessary optimality condition. The important case of delayed variational problems with higher-order derivatives is considered as well.

description: We investigate the evolution of Bose-Einstein condensates falling under gravity and bouncing off a mirror formed by a far-detuned sheet of light. After reflection, the atomic density profile develops splitting and interference structures which depend on the drop height, on the strength of the light sheet, as well as on the initial mean field energy and size of the condensate. We compare experimental results with simulations of the Gross-Pitaevski equation. A comparison with the behavior of bouncing thermal clouds allows us to identify quantum features specific for condensates. © 1999 The American Physical Society.
title: Évaluation d’un programme de formation initiale interprofessionnelle par la simulation : le parcours de soins périnatal de l’éclampsie

description: Objectif. La collaboration interprofessionnelle devient un enjeu majeur pour la formation initiale et continue des professionnels de santé. Les comportements qu’elle sous-tend ne sont pas naturels et la simulation est un moyen important pour promouvoir ce changement de culture. Le présent travail décrit la construction et la mise en œuvre d’un programme de simulation durant une journée complète, centrée sur une situation obstétricale (éclampsie) et envisageant, par quatre scénarios successifs et leurs débriefings associés, des situations interprofessionnelles distinctes mais complémentaires. Matériel et méthodes. Quatre scénarios successifs, chacun suivi d’un débriefing spécifique, ont été mis au point par un groupe de travail interprofessionnel. Une thématique obstétricale commune mais éclairant les différents aspects de la prise en charge médicale (urgences et situations de crise maternelle et néonatale, transmission interprofessionnelle, relation soignants et patient/famille) a été choisie. Les personnels impliqués dans la formation relevaient de tous les métiers rencontrés en obstétrique. Un questionnaire en fin de journée évaluait la formation selon les niveaux 1 à 3 de Kirkpatrick (réaction, apprentissage et comportement) en utilisant des échelles de Likert. Résultats. L’interprofessionnalité et, notamment, le débriefing commun des sessions ont enrichi les échanges et le partage d’information dans le groupe. Pour les participants, cette formation aura un impact positif sur leur activité professionnelle. Discussion. Cet exemple souligne la faisabilité de la mise en œuvre d’une formation interprofessionnelle pour des professionnels de santé travaillant dans une activité médicale dans laquelle les situations de crise sont fréquentes et la collaboration entre les membres de l’équipe, essentielle pour améliorer les pratiques et les résultats des soins.

description: Bark beetle outbreaks are responsible for the loss of large areas of forests and in recent years they appear to be increasing in frequency and magnitude as a result of climate change. The aim of this study is to develop a new standardized methodology for the automatic detection of the degree of damage on single fir trees caused by bark beetle attacks using a simple GIS-based model. The classification approach is based on the degree of tree canopy defoliation observed (white pixels) in the UAV-acquired very high resolution RGB orthophotos. We defined six degrees (categories) of damage (healthy, four infested levels and dead) based on the ratio of white pixel to the total number of pixels of a given tree canopy. Category 1: <2.5% (no defoliation); Category 2: 2.5–10% (very low defoliation); Category 3: 10–25% (low defoliation); Category 4: 25–50% (medium defoliation); Category 5: 50–75% (high defoliation), and finally Category 6: >75% (dead). The definition of “white pixel” is crucial, since light conditions during image acquisition drastically affect pixel values. Thus, whiteness was defined as the ratio of red pixel value to the blue pixel value of every single pixel in relation to the ratio of the mean red and mean blue value of the whole orthomosaic. The results show that in an area of 4 ha, out of the 1376 trees, 277 were healthy, 948 were infested (Cat 2, 628; Cat 3, 244; Cat 4, 64; Cat 5, 12), and 151 were dead (Cat 6). The validation led to an average precision of 62%, with Cat 1 and Cat 6 reaching a precision of 73% and 94%, respectively. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

description: We investigate decoupling, one of the most important primitives in quantum Shannon theory, by replacing the uniformly distributed random unitaries commonly used to achieve the protocol, with repeated applications of random unitaries diagonal in the Pauli-Z and -X bases. This strategy was recently shown to achieve an approximate unitary 2-design after a number of repetitions of the process, which implies that the strategy gradually achieves decoupling. Here, we prove that even fewer repetitions of the process achieve decoupling at the same rate as that with the uniform ones, showing that rather imprecise approximations of unitary 2-designs are sufficient for decoupling. We also briefly discuss efficient implementations of them and implications of our decoupling theorem to coherent state merging and relative thermalisation.
