description: In this paper we demonstrate that radiation patterns could cause flow-like behaviour without any reference to hydrodynamic description. For that purpose we use a statistical ensemble of radiating dipoles, motivated by the investigation of the equivalent photon yield produced by decelerating charges. For the elliptic asymmetry factor we find a reasonable agreement with experimental data.

description: Detection models trained by one party (including server) may face severe performance degradation when distributed to other users (clients). Federated learning can enable multi-party collaborative learning without leaking client data. In this paper, we focus on a special cross-domain scenario in which the server has large-scale labeled data and multiple clients only have a small amount of labeled data; meanwhile, there exist differences in data distributions among the clients. In this case, traditional federated learning methods can't help a client learn both the global knowledge of all participants and its own unique knowledge. To make up for this limitation, we propose a cross-domain federated object detection framework, named FedOD. The proposed framework first performs the federated training to obtain a public global aggregated model through multi-teacher distillation, and sends the aggregated model back to each client for fine-tuning its personalized local model. After a few rounds of communication, on each client we can perform weighted ensemble inference on the public global model and the personalized local model. We establish a federated object detection dataset which has significant background differences and instance differences based on multiple public autonomous driving datasets, and then conduct extensive experiments on the dataset. The experimental results validate the effectiveness of the proposed method.

description: Correlated oxides and related heterostructures are intriguing for developing future multifunctional devices by exploiting their exotic properties, but their integration with other materials, especially on Si-based platforms, is challenging. Here, van der Waals heterostructures of La$_{0.7}$Sr$_{0.3}$MnO$_3$ (LSMO), a correlated manganite perovskite, and MoS$_2$ are demonstrated on Si substrates with multiple functions. To overcome the problems due to the incompatible growth process, technologies involving freestanding LSMO membranes and van der Waals force-mediated transfer are used to fabricate the LSMO-MoS$_2$ heterostructures. The LSMO-MoS$_2$ heterostructures exhibit a gate-tunable rectifying behavior, based on which metal-semiconductor field-effect transistors (MESFETs) with on-off ratios of over 104 can be achieved. The LSMO-MoS$_2$ heterostructures can function as photodiodes displaying considerable open-circuit voltages and photocurrents. In addition, the colossal magnetoresistance of LSMO endows the LSMO-MoS$_2$ heterostructures with an electrically tunable magnetoresponse at room temperature. This work not only proves the applicability of the LSMO-MoS$_2$ heterostructure devices on Si-based platform but also demonstrates a paradigm to create multifunctional heterostructures from materials with disparate properties.

description: Math word problem solver requires both precise relation reasoning about quantities in the text and reliable generation for the diverse equation. Current sequence-to-tree or relation extraction methods regard this only from a fixed view, struggling to simultaneously handle complex semantics and diverse equations. However, human solving naturally involves two consistent reasoning views: top-down and bottom-up, just as math equations also can be expressed in multiple equivalent forms: pre-order and post-order. We propose a multi-view consistent contrastive learning for a more complete semantics-to-equation mapping. The entire process is decoupled into two independent but consistent views: top-down decomposition and bottom-up construction, and the two reasoning views are aligned in multi-granularity for consistency, enhancing global generation and precise reasoning. Experiments on multiple datasets across two languages show our approach significantly outperforms the existing baselines, especially on complex problems. We also show after consistent alignment, multi-view can absorb the merits of both views and generate more diverse results consistent with the mathematical laws.

Anomalously large relaxation times in dissipative lattice models beyond the non-Hermitian skin effect

description: We show for generic quantum non-Hermitian tight-binding models that relaxation timescales of local observables are not controlled by the localization length $ξ_{\rm loc}$ associated with the non-Hermitian skin effect, contrary to popular belief. Instead, interference between eigenvectors effectively makes the extreme localization of modes largely irrelevant to relaxation; this is ultimately a consequence of causality and locality. Focusing on the paradigmatic Hatano-Nelson model, we demonstrate that there exists instead a much larger length scale $ξ_{\rm prop}$ which controls the rate of decay towards the steady state. Further, varying $ξ_{\rm prop}$ can lead to anomalously large relaxation times that scale with system size, or to the expected behavior where the dissipative gap correctly predicts the rate of decay. Our work highlights an important aspect of the non-Hermitian skin effect: the exceptional sensitivity to boundary conditions here necessarily takes a finite amount of time to manifest itself.

description: Представлены результаты прикладных исследований по получению трехслойного металломатричного структурного композита в разных температурных условиях сварки давлением. В эксперименте показана возможность использования в качестве упрочняющего элемента структурного слоя титанового сплава Ti–6Al–4V с нанокристаллической структурой. Металлографические исследования показали, что при получения композита при температуре 900 °С в упрочняющем элементе наблюдается рост зерен до микрокристаллических размеров. С понижением температуры до температуры 700 °С изменение размера зерен в упрочняющем элементе не обнаружено, хотя размер зерен a-фазы незначительно подрос по сравнению с исходным. Описаны геометрические изменения микропор в зоне твердофазного соединения, динамика роста и пространственного расположения зерен. Результатами механических испытаний на растяжение подтверждено, что прочность композита, полученного при температуре 700 °С, может превосходить прочность композита, полученного при температуре 900 °С. Изучена схема разрушения композита в зоне твердофазного соединения при испытании на растяжение при комнатной температуре. Выделены три этапа разрушения и проанализированы характер и механизм разрушения композита. Результаты механических испытаний композитного материала показали, что его механическое поведение зависит от температуры сварки. Отмечено, что разрушение начинается под действием главных напряжений, развиваясь по нормали к ним. В частности, было отмечено, что при достижении менее прочного, но более пластичного слоя в композите наблюдается резкий рост пластических деформаций, что оказывает тормозящее действие на развитие трещины, которая при этом меняет траекторию распространения.

description: This article proposes a cognitive mechanism of humour of general applicability, not restricted to verbal communication. It is indebted to Raskin's concept of script overlap, and conforms to the incongruity-resolution theoretical framework, but it is built on the notion of constraint, an abstract correspondence between sets of data. Under this view, script overlap is an outcome of a more abstractly described phenomenon, constraint overlap. The important concept of the overlooked argument is introduced to characterise the two overlapping constraints -- overt and covert. Their inputs and outputs are not directly encoded in utterances, but implicated by them, and their overlap results in another overlap at the level of the communicated utterances, that the incongruity reveals. Our hypothesis assumes as a given that the evocation of such constraints is a cognitive effect of the inferential process by which a hearer interprets utterances. We base this assumption on Hofstadter's theory of analogy-making as the essence of human thought. By substituting "stimuli" of any kind for "utterances" in this model, we obtain a mechanism as easily applicable to non-verbal communication -- slapstick, cartoons -- and we propose it describes the necessary and sufficient conditions for a communicative act in any modality to carry humour.

description: Current object detectors typically have a feature pyramid (FP) module for multi-level feature fusion (MFF) which aims to mitigate the gap between features from different levels and form a comprehensive object representation to achieve better detection performance. However, they usually require heavy cross-level connections or iterative refinement to obtain better MFF result, making them complicated in structure and inefficient in computation. To address these issues, we propose a novel and efficient context modeling mechanism that can help existing FPs deliver better MFF results while reducing the computational costs effectively. In particular, we introduce a novel insight that comprehensive contexts can be decomposed and condensed into two types of representations for higher efficiency. The two representations include a locally concentrated representation and a globally summarized representation, where the former focuses on extracting context cues from nearby areas while the latter extracts key representations of the whole image scene as global context cues. By collecting the condensed contexts, we employ a Transformer decoder to investigate the relations between them and each local feature from the FP and then refine the MFF results accordingly. As a result, we obtain a simple and light-weight Transformer-based Context Condensation (TCC) module, which can boost various FPs and lower their computational costs simultaneously. Extensive experimental results on the challenging MS COCO dataset show that TCC is compatible to four representative FPs and consistently improves their detection accuracy by up to 7.8 % in terms of average precision and reduce their complexities by up to around 20% in terms of GFLOPs, helping them achieve state-of-the-art performance more efficiently. Code will be released.

description: We review our current understanding on the outer envelope structures of massive stars based on three dimensional (3D) radiation hydrodynamic simulations. We briefly summarize the fundamental issues to construct hydrostatic one dimensional (1D) stellar evolution models when stellar luminosity approaches the Eddington value. Radiation hydrodynamic simulations in 3D covering the mass range from $13M_{\odot}$ to $80M_{\odot}$ always find a dynamic envelope structure with the time-averaged radial profiles matching 1D models with an adjusted mixing length parameter when convection is subsonic. Supersonic turbulence and episodic mass loss are generally found in 3D models when stellar luminosity is super-Eddington locally due to the opacity peaks and convection is inefficient. Turbulent pressure plays an important role in supporting the outer envelope, which makes the photosphere more extended than predictions from 1D models. Massive star lightcurves are always found to vary with a characteristic timescale consistent with the thermal time scale at the location of the iron opacity peak. The amplitude of the variability as well as the power spectrum can explain the commonly observed stochastic low frequency variability of mass stars observed by TESS over a wide range of parameters in the HR diagram. The 3D simulations can also explain the ubiquitous macro-turbulence that is needed for spectroscopic fitting in massive stars. Implications of the 3D simulations for improving 1D stellar evolution models are also discussed.

description: Automatic car damage detection has attracted significant attention in the car insurance business. However, due to the lack of high-quality and publicly available datasets, we can hardly learn a feasible model for car damage detection. To this end, we contribute with Car Damage Detection (CarDD), the first public large-scale dataset designed for vision-based car damage detection and segmentation. Our CarDD contains 4,000 highresolution car damage images with over 9,000 well-annotated instances of six damage categories. We detail the image collection, selection, and annotation processes, and present a statistical dataset analysis. Furthermore, we conduct extensive experiments on CarDD with state-of-the-art deep methods for different tasks and provide comprehensive analyses to highlight the specialty of car damage detection. CarDD dataset and the source code are available at https://cardd-ustc.github.io.

We obtain the density of zero roots, surface energies and elementary excitations in different regimes of model parameters. Due to the competition of various interactions, the surface energy and excited spectrum show many different pictures from those of the Heisenberg spin chain.

description: Isolated quantum systems follow the unitary evolution, which guarantees the full many body state always keeps a constant entropy as its initial one. In comparison, the local subsystems exhibit relaxation behavior and evolve towards certain steady states, which is called the local relaxation. Here we consider the local dynamics of finite many body system with Ising interaction. In both strong and weak coupling situations, the local observables exhibit similar relaxation behavior as the macroscopic thermodynamics; due to the finite size effect, recurrence appears after a certain typical time. Especially, we find that the total correlation of this system approximately exhibits a monotonic increasing envelope in both strong and weak coupling cases, which corresponds to the irreversible entropy production in the standard macroscopic thermodynamics. Moreover, the possible maximum of such total correlation calculated under proper constraints also coincides well with the exact result of time dependent evolution.

description: We investigate theoretically how the proximity effect in superconductor/ferromagnet hybrid structures with intrinsic spin-orbit coupling manifests in the density of states and critical temperature. To describe a general scenario, we allow for both Rashba and Dresselhaus type spin-orbit coupling. Our results are obtained via the quasiclassical theory of superconductivity, extended to include spin-orbit coupling in the Usadel equation and Kupriyanov--Lukichev boundary conditions. Unlike previous works, we have derived a Riccati parametrization of the Usadel equation with spin-orbit coupling which allows us to address the full proximity regime. First, we consider the density of states in both SF bilayers and SFS trilayers, where the spectroscopic features in the latter case are sensitive to the phase difference between the two superconductors. We find that the presence of spin-orbit coupling leaves clear spectroscopic fingerprints in the density of states due to its role in creating spin-triplet Cooper pairs. Unlike SF and SFS structures without spin-orbit coupling, the density of states in the present case depends strongly on the direction of magnetization. We show that the spin-orbit coupling can stabilize singlet superconductivity even in the presence of a strong exchange field $h \gg Δ$. This leads to the possibility of a magnetically tunable minigap: changing the direction of the exchange field opens and closes the minigap. We also determine how the critical temperature $T_c$ of an SF bilayer is affected by spin-orbit coupling and demonstrate that one can achieve a spin-valve effect with a single ferromagnet. We find that $T_c$ displays highly non-monotonic behavior both as a function of the magnetization direction and the type and direction of the spin-orbit coupling, offering a new way to exert control over the superconductivity of proximity structures.

After that, a series of benchmark experiments are presented to evaluate the performance of the GREB-ISM in long-term mean state and transition simulations. Last but not least, we applied the GREB-ISM to understand the importance and relevant physics of climate-ice sheet feedback by using a series of sensitivity experiments.

description: Millimetre-wave observations represent an important tool for Cosmology studies. The Line Intensity Mapping (LIM) technique has been proposed to map in three dimensions the specific intensity due to line (e.g. [CII], CO) emission, for example from the primordial galaxies, as a function of redshift. Hyper-spectral integrated devices have the potential to replace the current Fourier transform, or the planned Fabry-Perot-based instruments operating at millimetre and sub-millimetre wavelengths. The aim is to perform hyper-spectral mapping, with a spectral resolution R= 100-1000, over large, i.e. thousands of beams, instantaneous patches of the Sky. The innovative integrated device that we have developed allows avoiding moving parts, complicated and/or dispersive optics or tunable filters to be operated at cryogenic temperatures. The prototype hyper-spectral focal plane is sensitive in the 75-90GHz range and contains nineteen horns for sixteen spectral-imaging channels, each selecting a frequency band of about 0.1GHz. For each channel a conical horn antenna, coupled to a planar superconducting resonant absorber made of thin aluminium, collects the radiation. A capacitively coupled titanium-aluminium bilayer Lumped Element Kinetic Inductance Detector (LEKID) is then in charge of dissipating and sensing the super-current established in the resonant absorber. The prototype is fabricated with only two photo-lithography steps over a commercial mono-crystalline sapphire substrate. It exhibits a spectral resolution of about 800. The optical noise equivalent power of the best channels is in the observational relevant 4E-17W/sqrt(Hz) range. The average sensitivity of all the channels is around 1E-16W/sqrt(Hz). The device, as expected from 3-D simulations, is polarisation-sensitive, paving the way to spectro-polarimetry measurements over very large instantaneous field-of-views.

Computations of shock-wave/boundary layer interactions over fins in turbulent flow

Subjects: Aerospace engineering not elsewhere classified

description: High speed flows in engineering applications are often characterized by shock-wave/boundary layer interactions (SWBLI) and three-dimensional flows. This thesis aims to study commonly employed turbulence models in the context of configurations featuring SWBLI and 3D flows. Computational Fluid Dynamics (CFD) simulations of flow over a 20 degree isentropic compression curved fin were performed, and the results were compared with published experimental data. Two variations of the Spalart-Allmaras (SA) turbulence model, and two variations of the Menter Shear Stress Transport (SST) turbulence model were tested, and their ability to predict mean flow data was compared. All four models predict the correct flow structure, but the SA models display higher error in predicting Pitot pressure in the curved fin 3D boundary layer. CFD simulations of flow over a sharp fin were performed using the same four turbulence models, and mean flow data were compared to published experimental and computational data. Simulated flow profiles showed good accuracy in the regions away from the shock structure, but did not accurately predict flow in the supersonic regions in the vicinity of the shock wave. Time-accurate IDDES simulations of both configurations were performed, and neither configuration showed any deviation from the steady state solution.

description: The development of bilingual dictionaries to medieval translations presents diverse difficulties. These result from two types of philological circumstances: a) the asymmetry between the source language and the target language; and b) the varying available sources of both the original and translated texts. In particular, the full critical edition of Tihova of Constantine of Preslav's Uchitel'noe evangelie ('Didactic Gospel') gives a relatively good idea of the Old Church Slavonic translation but not of its Greek source text. This is due to the fact that Cramer's edition of the catenae - used as the parallel text in it - is based on several codices whose text does not fully coincide with the Slavonic. This leads to the addition of the newly-discovered parallels from Byzantine manuscripts and John Chrysostom's homilies. Our approach to these issues is a step-wise process with two main goals: a) to facilitate the philological annotation of input data and b) to consider the manifestations of the mentioned challenges, first, separately in order to simplify their resolution, and, then, in their combination. We demonstrate how we model various types of asymmetric translation correlates and the variability resulting from the pluralism of sources. We also demonstrate how all these constructions are being modelled and processed into the final indices. Our approach is designed with generalisation in mind and is intended to be applicable also for other translations from Greek into Old Church Slavonic.

description: Two-dimensional (2D) materials have received extensive research attentions over the past two decades due to their intriguing physical properties (such as the ultrahigh mobility and strong light-matter interaction at atomic thickness) and a broad range of potential applications (especially in the fields of electronics and optoelectronics). The growth of single-crystal 2D materials is the prerequisite to realize 2D-based high-performance applications. In this review, we aim to provide an in-depth analysis of the state-of-the-art technology for the growth and applications of 2D materials, with particular emphasis on single crystals. We first summarize the major growth strategies for monolayer 2D single crystals. Following that, we discuss the growth of multilayer single crystals, including the control of thickness, stacking sequence, and heterostructure composition. Then we highlight the exploration of 2D single crystals in electronic and optoelectronic devices. Finally, a perspective is given to outline the research opportunities and the remaining challenges in this field.

description: Körner introduced the notion of graph entropy in 1973 as the minimal code rate of a natural coding problem where not all pairs of letters can be distinguished in the alphabet. Later it turned out that it can be expressed as the solution of a minimization problem over the so-called vertex-packing polytope. In this paper we generalize this notion to graphons. We show that the analogous minimization problem provides an upper bound for graphon entropy. We also give a lower bound in the shape of a maximization problem. The main result of the paper is that for most graphons these two bounds actually coincide and hence precisely determine the entropy in question. Furthermore, graphon entropy has a nice connection to the fractional chromatic number and the fractional clique number.
Facebook 'Regulation': a process not a text
Creators: name: Andrews, Leighton
Publisher: name: Zenodo

description: Discussions of platform governance frequently focus on issues of platform liability and online harm to the exclusion of other issues; perpetuate the myth that ‘the internet’ is unregulated; reinforce the same internet exceptionalism as the Silicon Valley companies themselves; and, by adopting the language of governance rather than regulation, diminish the role of the state. Over the last three years, UK governments, lawmakers and regulators, with expert advice, have contributed to the development of a broader range of regulatory concerns and options, leading to an emergent political economy of advertiser-funded platforms. These politicians and regulators have engaged in a process of sense-making, building their discursive capacity in a range of technical and novel issues. Studying an ‘actually existing’ regulatory process as it emerges enables us to look afresh at concepts of platform regulation and governance. This working paper has a particular focus on the regulatory approach to Facebook, which is presented as a case study. But it engages more widely with the issues of platform regulation through a careful interpretive analysis of official documentation from the UK government, regulatory and parliamentary bodies, and company reports. The regulatory process uncovered builds on existing regulatory frameworks and illustrates that platform regulation is a process, not a finished text.

description: Many recent numerical studies have argued that cosmic rays (CRs) from supernovae (SNe) or active galactic nuclei (AGN) could play a crucial role in galaxy formation, in particular by establishing a CR-pressure dominated circum-galactic medium (CGM). But explicit CR-magneto-hydrodynamics (CR-MHD) remains computationally expensive, and it is not clear whether those results can be applied to simulations that do not explicitly treat magnetic fields or resolved ISM phase structure. We therefore present an intentionally extremely-simplified sub-grid model for CRs, which attempts to capture the key qualitative behaviors of greatest interest for those interested in simulations or semi-analytic models including some approximate CR effects on galactic (>kpc) scales, while imposing negligible computational overhead. The model is numerically akin to some recently-developed sub-grid models for radiative feedback, and allows for a simple constant parameterization of the CR diffusivity and/or streaming speed; it allows for an arbitrary distribution of sources (proportional to black hole accretion rates or star-particle SNe rates or gas/galaxy star formation rates), and interpolates between the limits where CRs escape the galaxies with negligible losses and those where CRs lose most of their energy catastrophically before escape (relevant in e.g. starburst galaxies). The numerical equations are solved trivially alongside gravity in most codes. We compare this to explicit CR-MHD simulations and discuss where the (many) sub-grid approximations break down, and what drives the major sources of uncertainty.

description: A morph is a combination of two separate facial images and contains identity information of two different people. When used in an identity document, both people can be authenticated by a biometric Face Recognition (FR) system. Morphs can be generated using either a landmark-based approach or approaches based on deep learning such as Generative Adversarial Networks (GAN). In a recent paper, we introduced a \emph{worst-case} upper bound on how challenging morphing attacks can be for an FR system. The closer morphs are to this upper bound, the bigger the challenge they pose to FR. We introduced an approach with which it was possible to generate morphs that approximate this upper bound for a known FR system (white box), but not for unknown (black box) FR systems. In this paper, we introduce a morph generation method that can approximate worst-case morphs even when the FR system is not known. A key contribution is that we include the goal of generating difficult morphs \emph{during} training. Our method is based on Adversarially Learned Inference (ALI) and uses concepts from Wasserstein GANs trained with Gradient Penalty, which were introduced to stabilise the training of GANs. We include these concepts to achieve similar improvement in training stability and call the resulting method Wasserstein ALI (WALI). We finetune WALI using loss functions designed specifically to improve the ability to manipulate identity information in facial images and show how it can generate morphs that are more challenging for FR systems than landmark- or GAN-based morphs. We also show how our findings can be used to improve MIPGAN, an existing StyleGAN-based morph generator.

description: The patent realizes ISO 14040 for LCA (Life Cycle Assessment) to calculate primarily a descent
insurance premium. There are other ecological, bio- monitor, marketing and Connoisseur lab actions.
The patent evolves fishery from an agriculture Odyssey to an industrial and quality business.
The platform has various tanks, pods, water pillows, geotextile lakes on the ground or floated. These are interconnected with sampling, volumetric, monitoring hardware and
software advices. Fishermen follow a specific rule that says “fish effluents generated in one tank
is food for another fish or sea food in another tank”. Then according to their own analysis of the
basic concept they propose water interchange form another tank. Technically the invention uses an YPSILON conjunction, a custom multiplexor and a bidirectional pumping station
to transfer water around the fishery.

description: Face recognition systems are widely deployed for biometric authentication. Despite this, it is well-known that, without any safeguards, face recognition systems are highly vulnerable to presentation attacks. In response to this security issue, several promising methods for detecting presentation attacks have been proposed which show high performance on existing benchmarks. However, an ongoing challenge is the generalization of presentation attack detection methods to unseen and new attack types. To this end, we propose a new T-shirt Face Presentation Attack (TFPA) database of 1,608 T-shirt attacks using 100 unique presentation attack instruments. In an extensive evaluation, we show that this type of attack can compromise the security of face recognition systems and that some state-of-the-art attack detection mechanisms trained on popular benchmarks fail to robustly generalize to the new attacks. Further, we propose three new methods for detecting T-shirt attack images, one which relies on the statistical differences between depth maps of bona fide images and T-shirt attacks, an anomaly detection approach trained on features only extracted from bona fide RGB images, and a fusion approach which achieves competitive detection performance.
LONG- AND SHORT-TERM OXYGEN DYNAMICS IN MYSTERY BASIN, A FLORIDA BAY BASIN
Creators: name: Rok, Adam

description: Recent phytoplankton blooms, seagrass die-offs and major storms have significantly altered benthic communities and nutrient element cycling in Florida Bay. Central Florida Bay, where numerous small basins isolated by shallow shoals are located, has experienced many of these disturbances. New insights about the dynamics of this system were obtained through the quantification of temporal variability in physical and biogeochemical processes in Mystery Basin. Time-series measurements of dissolved oxygen concentration distributions, sediment oxygen demand, current speed and direction and meteorological data show a system that features dramatic daily oxygen fluctuations (70 µM a day). Regular day time supersaturation leads to net out gassing of oxygen and night time sub-saturation leads to diffusion of oxygen into the basin, with the average being a slightly net positive source of oxygen.  Longer term fluctuations in oxygen appear to be controlled by Basin water temperatures, which themselves are dominated by atmospheric conditions.

description: Les erreurs médicamenteuses involontaires peuvent entraîner de nombreuses conséquences néfastes sur le patient, mais également sur le professionnel de santé qui en commet. Ces événements indésirables risquent d’impacter de manière importante la sphère biopsychosociale de l’infirmière, tant au niveau personnel que professionnel. Le soignant impliqué dans cet incident sera ainsi décrit comme « seconde victime ». Bien souvent, l’erreur involontaire tient d’une combinaison de différents facteurs favorables à la survenue de cette dernière. Toutefois, du fait de la culture du perfectionnisme et du blâme dans les soins, c’est la responsabilité individuelle de l’infirmière autrice de l’erreur qui est mise en cause.

Publisher: name: No Publisher Supplied
Year: 2022

description: Purpose of Project:There are challenges in reducing the amount of waste anesthetic gas released into the environment, but some changes are within the clinical practitioner's grasp. A point of emphasis for this project was that during pediatric intubation, shutting off fresh gas flows instead of the vaporizer, would help reduce the exposure of anesthetic gas into the environment. A broader goal of the project was to create more environmentally conscious anesthesia providers who makes clinical practice decisions based on the patient’s well-being as well as the potential environmental consequences.Methodology:A PSA video was created and made available on YouTube illustrating the pros and cons of this recommendation by using dry ice vapor in the anesthesia circuit to simulate fresh gas flow. A pre and post-test survey was given to participants to ascertain if watching the PSA had any effect on their reported knowledge base as well as their willingness to change their practice due to the information obtained.Results:Results of the pre- and post-test survey showed 69 responses where there was a statistically significant willingness to change anesthetic practice (Z = -2.274, p = 0.023), using the Wilcoxon signed-rank test. Implications for Practice: The positive correlation between showing the PSA video of the effects of anesthetic gases on the environment and the willingness to change anesthetic practice regarding fresh gas flows and pediatric intubation, shows that it is possible for a clinical practice change.

description: La dépression du post-partum (DPP) survient après la naissance d’un enfant ettouche entre 10 et 20% des femmes ainsi que 10% des hommes. La DPP est peu connuedans la société et le nombre de personnes qui en souffrent est largement sous-estimé. Le faitque les hommes puissent, eux-aussi, être atteint de DPP est probablement l’aspect le plustabou et l’un des moins visibles de cette maladie. Pour beaucoup, la naissance d’un enfant estvue comme l’une des plus belles périodes de la vie. L'écart entre les attentes concernant laparentalité et la réalité éprouvante à laquelle les parents doivent faire face est conséquent.
