description: Cocoa production in Côte d’Ivoire is generally based on “full sun” crops. However, the presence of traditional agroforestry systems based on cocoa (AFSc) has been highlighted in several regions including the Centre and Centre-West. This study aimed to provide information on the financial profitability and the potential economic value of simple, mixed and complex AFSc types identified in central Côte d’Ivoire. A socio-economic survey and direct observations carried out among farmers with these AFSc types, revealed an annual average cocoa production of 207.7 kgha−1 (i.e. US$323.9). This income does not vary significantly from one type to another. Fruit species associated with cocoa trees yield an average of US$32.39 ha-1yr-1. This fruit contribution is more important in simple AFSc than in the two other types. Considering the profitability of cocoa trees and associated species, no system is more profitable than the other. However, the potential economic value of the stored carbon and the other benefits that the complex AFSc type provides to farmers make this type more efficient and sustainable than the two others considering ecosystem services. We therefore recommend that payment for ecosystems services be considered if one would like to promote complex cocoa agroforestry systems in the study areas.

description: Electric transport and scanning tunneling spectrum (STS) have been investigated on polycrystalline samples of the new superconductor Bi4O4S3. A weak insulating behavior in the resistive curve has been induced in the normal state when the superconductivity is suppressed by applying a magnetic field. Interestingly, a kink appears on the temperature dependence of resistivity near 4 K at all high magnetic fields above 1 T when the bulk superconductivity is completely suppressed. This kink associated with the upper critical field as well as the wide range of excess conductance at low field and high temperature are explained as the possible evidence of strong superconducting fluctuation. From the tunneling spectra, a superconducting gap of about 3 meV is frequently observed yielding a ratio of 2Δ/(kB*Tc) ~ 16.6. This value is much larger than the one predicted by the BCS theory in the weak coupling regime (2Δ/(kB*Tc) ~ 3.53), which suggests the strong coupling superconductivity in the present system. Furthermore, the gapped feature persists on the spectra until 14 K in the STS measurement, which suggests a prominent fluctuation region of superconductivity. Such superconducting fluctuation can survive at very high magnetic fields, which are far beyond the critical fields for bulk superconductivity as inferred both from electric transport and tunneling measurements.

title: THE LINKS BETWEEN GULF OF MEXICO SEAFLOOR CHARACTERISTICS AND PETROLEUM HYDROCARBONS FOLLOWING THE DEEPWATER HORIZON OIL SPILL
Creators: name: Schindler, Kimberly
Publisher: name: University of Kentucky Libraries
Year: 2019

description: The Gulf of Mexico (GoMx) is among the most productive regions for offshore oil and natural gas recovery. In 2010, the Deepwater Horizon (DWH) drilling rig exploded, burned for three days, sank, and released over 4 million barrels of oil in the subsequent 84 days before it was capped. Some oil was buoyant enough to float to the ocean surface, where some was removed via a myriad techniques. Importantly, a plume of oil remained suspended in the water column at approximately 1,100 m water depth, where it drove a marine snow event, and deposited large quantities of oil on the seafloor.

The northern GoMx seafloor is complex and dynamic. Submarine canyons, mounds, channels, and salt domes dominate the seafloor along the continental slope surrounding the DWH well. Using high-resolution bathymetric data, variables derived to characterize the seafloor (water depth, distance, slope, and aspect), and spatial relationships between seafloor stations and the DWH well, relationships between concentrations, fluxes and inventories of polycyclic aromatic hydrocarbons, and other seafloor variables were hypothesized to be statistically significantly related. The most significant seafloor characteristic to predict distributions was water depth, followed by distance, relative aspect, and slope.

description:

Gli studi sociali non hanno mai elaborato una metodologia condivisa e anche per questo non riescono a svolgere il loro ruolo di coordinamento delle riflessioni sull’intreccio tra aspetti economici e politico giuridici della moderna società complessa. Anche per questa mancanza di coordinamento, il dibattito pubblico si frammenta e si sbilancia sull’'inevitabile superficialità dei mass media e dei social.  Il volume sostiene che l’antica tradizione tecnica del diritto può validamente contribuire allo studio della socialità, aggiungendo all’interpretazione del dato normativo quella del dato sociale. Il testo propone una metodologia di studio sociale in cui anche il diritto può facilmente calarsi, e che offre anche spunti utili ai giuristi come tecnici, essi riguardano il rapporto tra diritto e politica, giudizio di fatto, interpretazione, discrezionalità, autotutela amministrativa e rimedi contro il suo cattivo esercizio.

description: Objectif. Suite aux deux cas confirmés d’infection à Mycobacterium chimaera identifiés en 2015, une recherche rétrospective de cas après un acte de chirurgie cardiaque sous circulation extracorporelle (CEC) et une enquête sur les pratiques liées aux matériels de CEC en France ont été mises en œuvre. Méthode. L’enquête a ciblé les établissements de santé (ES) qui pratiquent des actes de chirurgie cardiaque sous CEC en France. Les informations recueillies par questionnaire portaient sur la période du 1er janvier 2015 au 31 juin 2017. Résultats. Parmi les 61 services de chirurgie cardiaque sollicités, 56 (92%) ont participé à l’enquête. Aucun établissement n’a déclaré de cas d’infection invasive à M. chimaera depuis 2015. L’utilisation, pour la CEC, de 227 générateurs thermiques (GT) a été déclarée par les ES participants, soit 5,8 GT pour 1 000 interventions par an. Les recommandations des fabricants relatives à l’entretien des GT étaient appliquées par une minorité d’établissements (7%). Les contrôles microbiologiques de l’eau des GT ont montré que 56% d’entre eux étaient contaminés par des bactéries usuelles et 23% par des mycobactéries du complexe Mycobacterium avium. Conclusion. Les ES n’ont pas identifié de nouveau cas d’infection à M. chimaera mais la contamination des GT était importante. Les difficultés rencontrées par les ES dans la mise en œuvre des recommandations des fabricants pour l’entretien et le contrôle microbiologique des GT suggèrent la nécessité de recommandations nationales pour améliorer les pratiques d’entretien des matériels de CEC.

description: There has been a lot of research interest in modified gravity theories which utilise the Vainshtein mechanism to recover standard general relativity in regions with high matter density, such as the Dvali-Gabadadze-Porrati and Galileon models. The strong nonlinearity in the field equations of these theories implies that accurate theoretical predictions could only be made using high-resolution cosmological simulations. Previously, such simulations were usually done on regular meshes, which limits both their performance and the accuracy. In this paper, we report the development of a new algorithm and code, based on ECOSMOG, that uses adaptive mesh refinements to improve the efficiency and precision in simulating the models with Vainshtein mechanism. We have made various code tests against the numerical reliability, and found consistency with previous simulations. We also studied the velocity field in the self-accelerating branch of the DGP model. The code, parallelised using MPI, is suitable for large cosmological simulations of Galileon-type modified gravity theories.

description: In open chaotic systems the number of long-lived resonance states obeys a fractal Weyl law, which depends on the fractal dimension of the chaotic saddle. We study the generic case of a mixed phase space with regular and chaotic dynamics. We find a hierarchy of fractal Weyl laws, one for each region of the hierarchical decomposition of the chaotic phase-space component. This is based on our observation of hierarchical resonance states localizing on these regions. Numerically this is verified for the standard map and a hierarchical model system.

description: Un outil d’évaluation, permettant d’identifier le risque infectieux encouru par les patients exposés aux différentes pratiques de soins et de hiérarchiser les actions correctives à mener, a été créé et utilisé dans notre CHU. Méthode. Le respect des bonnes pratiques d’hygiène a été évalué par audits d’observation directe pour différents items, avec des grilles standardisées. La gravité pour le patient des conséquences de la non-conformité a été cotée a priori par l’hygiéniste. Les fréquences de non-conformité ont été recueillies lors des audits. La criticité (gravité x fréquence) ainsi observée a été présentée sur une carte des risques ou « heatmap ». Résultats. Depuis 2014, ce programme a été déployé dans toutes les unités d’hospitalisation de chirurgie et de médecine du CHU. Les pratiques relatives aux soins complexes étaient généralement maîtrisées mais les précautions standard étaient peu respectées. Un diagnostic « hygiène » a été établi à partir des tableaux de criticité et les résultats rapidement restitués aux unités concernées. Des réajustements immédiats ont été mis en place suite à une formation ciblée sur les points critiques ou non acceptables. Les résultats par spécialité ainsi qu’à l’échelle de l’établissement ont également été obtenus, ce qui a permis de disposer d’un indicateur de l’application des bonnes pratiques d’hygiène à l’échelle du CHU et de déceler les critères pour lesquels mener prioritairement des actions d’amélioration. Conclusion. Cet outil, simple à déployer et à analyser, paraît utilisable dans tout établissement de santé. Il constitue une aide pour choisir les actions d’amélioration prioritaires. Les résultats obtenus pourraient constituer un indicateur qualité.

description: We bootstrap the all-loop dynamic S-matrix for the homogeneous psu(1,1|2)^2 spin-chain believed to correspond to the discretization of the massive modes of string theory on AdS_3 x S^3 x T^4. The S-matrix is the tensor product of two copies of the su(1|1)^2 invariant S-matrix constructed recently for the d(2,1;alpha)^2 chain, and depends on two antisymmetric dressing phases. We write down the crossing equations that these phases have to satisfy. Furthermore, we present the corresponding Bethe Ansatz, which differs from the one previously conjectured, and discuss how our construction matches several recent perturbative calculations.

description: To understand the origin of bursty dynamics in natural and social processes we provide a general analysis framework, in which the temporal process is decomposed into sub-processes and then the bursts in sub-processes, called contextual bursts, are combined to collective bursts in the original process. For the combination of sub-processes, it is required to consider the distribution of different contexts over the original process. Based on minimal assumptions for inter-event time statistics, we present a theoretical analysis for the relationship between contextual and collective inter-event time distributions. Our analysis framework helps to exploit contextual information available in decomposable bursty dynamics.

description: The motion of particles in random potentials occurs in several natural phenomena ranging from the mobility of organelles within a biological cell to the diffusion of stars within a galaxy. A Brownian particle moving in the random optical potential associated to a speckle, i.e., a complex interference pattern generated by the scattering of coherent light by a random medium, provides an ideal mesoscopic model system to study such phenomena. Here, we derive a theory for the motion of a Brownian particle in a speckle and, in particular, we identify its universal characteristic timescale levering on the universal properties of speckles. This theoretical insight permits us to identify several interesting unexplored phenomena and applications. As an example of the former, we show the possibility of tuning anomalous diffusion continuously from subdiffusion to superdiffusion. As an example of the latter, we show the possibility of harnessing the speckle memory effect to perform some basic deterministic optical manipulation tasks such as guiding and sorting by employing random speckles, which might broaden the perspectives of optical manipulation for real-life applications by providing a simple and cost-effective technique.

description: We present a catalog covering 1.62 deg^2 of the COSMOS/UltraVISTA field with PSF-matched photometry in 30 photometric bands. The catalog covers the wavelength range 0.15um - 24um including the available GALEX, Subaru, CFHT, VISTA and Spitzer data. Catalog sources have been selected from the DR1 UltraVISTA Ks band imaging that reaches a depth of K_{s,tot} = 23.4 AB (90% completeness). The PSF-matched catalog is generated using position-dependent PSFs ensuring accurate colors across the entire field. Also included is a catalog of photometric redshifts (z_phot) for all galaxies computed with the EAZY code. Comparison with spectroscopy from the zCOSMOS 10k bright sample shows that up to z ~ 1.5 the z_phot are accurate to dz/(1 + z) = 0.013, with a catastrophic outlier fraction of only 1.6%. The z_phot also show good agreement with the z_phot from the NEWFIRM Medium Band Survey (NMBS) out to z ~ 3. A catalog of stellar masses and stellar population parameters for galaxies determined using the FAST spectral energy distribution fitting code is provided for all galaxies. Also included are rest-frame U-V and V-J colors, L_2800 and L_IR. The UVJ color-color diagram confirms that the galaxy bi-modality is well-established out to z ~ 2. Star-forming galaxies also obey a star forming "main sequence" out to z ~ 2.5, and this sequence evolves in a manner consistent with previous measurements. The COSMOS/UltraVISTA Ks-selected catalog covers a unique parameter space in both depth, area, and multi-wavelength coverage and promises to be a useful tool for studying the growth of the galaxy population out to z ~ 3 - 4.

Species abundances and lifetimes: from neutral to niche-stabilized communities
Creators: name: Pigolotti, Simone
name: Cencini, Massimo
Publisher: name: arXiv
Year: 2013
Subjects: subject: Populations and Evolution (q-bio.PE)

description: We study a stochastic community model able to interpolate from a neutral regime to a niche partitioned regime upon varying a single parameter tuning the intensity of niche stabilization, namely the difference between intraspecific and interspecific competition. By means of a self-consistent approach, we obtain an analytical expression for the species abundance distribution, in excellent agreement with stochastic simulations of the model. In the neutral limit, the Fisher log-series is recovered, while upon increasing the stabilization strength the species abundance distribution develops a maximum for species at intermediate abundances, corresponding to the emergence of a carrying capacity. Numerical studies of species extinction-time distribution show that niche-stabilization strongly affects also the dynamical properties of the system by increasing the average species lifetimes, while suppressing their fluctuations. The results are discussed in view of the niche-neutral debate and of their potential relevance to field data.

For the displaced, single-mode squeezed and two-mode squeezed harmonic oscillators, we derive the exact, closed-form expressions for their energies and wave functions. For the $k$th-order harmonic generation with $k\geq 3$, our result indicates that it does not have eigenfunctions and is thus ill-defined in the Bargmann-Hilbert space.

description: Most studies in the social sciences are designed to answer distinct research questions. However, the range of topics covered in a survey or interview may also include areas relevant to fields of research not primarily targeted by the scientists conducting the study. The study “Health behavior and Injuries in School Age” (GUS) presents such a case. Its primary goal was to identify causes of injuries in students in secondary education schools. However, with around 80 questions per student-questionnaire including different aspects of the personality, family environment, academic performance and social situation of the respondents, it provides a valuable asset for researchers from different disciplines and with various research interests.
 The data was collected by the Research Centre of Demographic Change (Forschungszentrum Demografischer Wandel, FZDW) at the Frankfurt University of Applied Sciences as a panel survey over the course of six annual waves from 2014 to 2020. The dataset is available for re-use at the Research Data Center at the Leibniz Institute for Educational Trajectories (Forschungsdatenzentrum, RDC LIfBi) and contains information from over 40,000 questionnaires. It also includes data from the heads of schools and the interviewers present during the classroom surveys.
 The presentation gives insights into the methods and field work of the GUS study and serves as an introduction into working with the data and documentation materials. It especially highlights the research potentials with a focus on topics relevant for educational research. Important variables both surveyed and generated are presented and examples of possible analyses are given.

description: We analyze the BPS solutions of minimal supergravity coupled to an anti-self-dual tensor multiplet in six dimensions and find solutions that fluctuate non-trivially as a function of two variables. We consider families of solutions coming from KKM monopoles fibered over Gibbons-Hawking metrics or, equivalently, non-trivial T^2 fibrations over an R3 base. We find smooth microstate geometries that depend upon many functions of one variable, but each such function depends upon a different direction inside the T^2 so that the complete solution depends non-trivially upon the whole T^2 . We comment on the implications of our results for the construction of a general superstratum.

description: We study multi-hadron systems with a single heavy quark (charm or bottom) in the limit of heavy quark mass. The spin degeneracy of the states with quantum numbers $(j+1/2)^{P}$ and $(j-1/2)^{P}$ for $j \neq 0$, known in a normal hadron, can be generalized to multi-hadron systems. The spin degeneracy is the universal phenomena for any multi-hadron systems with a single heavy quark, irrespective of their internal structures, including compact multi-quarks, hadronic molecules and exotic nuclei. We demonstrate the spin degeneracy in the hadronic systems formed by a heavy hadron effective theory; $P^{(\ast)}N$ states with a $P^{(\ast)}=\bar{D}^{(\ast)}$, $B^{(\ast)}$ meson and a nucleon $N$, and a $P^{(\ast)}$ meson in nuclear matter.

High-Efficiency Lucky Imaging

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: Lucky Imaging is now an established observing procedure that delivers near diffraction-limited images in the visible on ground-based telescopes up to ~2.5 m in diameter. Combined with low order adaptive optics it can deliver resolution several times better than that of the Hubble Space Telescope. Many images are taken at high speed as atmospheric turbulent effects appear static on these short timescales. The sharpest images are selected, shifted and added to give a much higher resolution than is normally possible in ground-based long exposure time observations. The method is relatively inefficient as a significant fraction of the frames are discarded because of their relatively poor quality. This paper shows that a new Lucky Imaging processing method involving selection in Fourier space can substantially improve the selection percentages. The results show that high resolution images with a large isoplanatic patch size may be obtained routinely both with conventional Lucky Imaging and with the new Lucky Fourier method. Other methods of improving the sensitivity of the method to faint reference stars are also described.

Year: 2023

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to test the relative influences of gender and partisan frames in the abortion rights issue. Respondents were assigned to one of three conditions based on gender and political party identification: a control condition stating that recent state bills have worked to restrict abortion, a gender condition which frames these bills as a gender debate, and a partisanship condition that frames the bills as a partisan debate. Following treatment, respondents were asked to rate the importance of the issue of abortion to them. A total of 2,118 respondents participated. Respondents were also asked to rate their perceived political efficacy around the abortion issue, level of gender discrimination in today’s society, and how well their party represents their views on abortion. This allowed for comparison of responses across frames.

We continue studying an inflationary model, in which before the slow roll inflation the universe is in a contracting phase, and fit the model with the Planck data. It is showed that this model may generate not only the power deficit at low-l, but also a large hemispherical power asymmetry in CMB. We also discuss the implication of the result to the eternal inflation scenario.

We have determined the spectral types of both components (L8+/-1, for the primary, agreeing with the discovery paper; T1.5+/-2 for the secondary, which was lacking spectroscopic type determination in the discovery paper) and, for the first time, their radial velocities (V_rad~23.1, 19.5 km/s) using optical spectra obtained at the Southern African Large Telescope (SALT) and other facilities located at the South African Astronomical Observatory (SAAO). The relative radial velocity of the two components is smaller than the range of orbital velocities for theoretically predicted masses, implying that they form a gravitationally bound system. We report resolved near-infrared JHK_S photometry from the IRSF telescope at the SAAO which yields colors consistent with the spectroscopically derived spectral types. The available kinematic and photometric information excludes the possibility that the object belongs to any of the known nearby young moving groups or associations. Simultaneous optical polarimetry observations taken at the SAAO 1.9-m give a non-detection with an upper limit of 0.07%. For the given spectral types and absolute magnitudes, 1Gyr theoretical models predict masses of 0.04--0.05 M_odot for the primary, and 0.03--0.05 M_odot for the secondary.

description: A solid state electronic nanodevice is an intrinsically open quantum system, exchanging both energy with the host material and carriers with connected reservoirs. Its out-of-equilibrium behavior is determined by a non-trivial interplay between electronic dissipation and decoherence induced by inelastic processes within the device, and the coupling of the latter to metallic electrodes. We propose a unified description, based on the density matrix formalism, that accounts for both these aspects, enabling to predict various steady-state as well as ultrafast nonequilibrium phenomena, nowadays experimentally accessible. More specifically, we derive a generalized density-matrix equation, particularly suitable for the design and optimization of a wide class of electronic and optoelectronic quantum devices. The power and flexibility of this approach is demonstrated with the application to a photoexcited triple-barrier nanodevice.

description: Context: New trial data and drug regimens that have become available in the last 2
years warrant an update to guidelines for antiretroviral therapy (ART) in human immunodeficiency
virus (HIV)–infected adults in resource-rich settings.
Objective: To provide current recommendations for the treatment of adult HIV infection
with ART and use of laboratory-monitoring tools. Guidelines include when to
start therapy and with what drugs, monitoring for response and toxic effects, special
considerations in therapy, and managing antiretroviral failure.
Data Sources, Study Selection, and Data Extraction: Data that had been published
or presented in abstract form at scientific conferences in the past 2 years were systematically
searched and reviewed by an International Antiviral Society–USA panel. The
panel reviewed available evidence and formed recommendations by full panel consensus.
Data Synthesis: Treatment is recommended for all adults with HIV infection; the strength
of the recommendation and the quality of the evidence increase with decreasing CD4
cell count and the presence of certain concurrent conditions. Recommended initial regimens
include 2 nucleoside reverse transcriptase inhibitors (tenofovir/emtricitabine or abacavir/
lamivudine) plus a nonnucleoside reverse transcriptase inhibitor (efavirenz), a ritonavirboosted
protease inhibitor (atazanavir or darunavir), or an integrase strand transfer inhibitor
(raltegravir). Alternatives in each class are recommended for patients with or at risk of
certain concurrent conditions. CD4 cell count and HIV-1 RNA level should be monitored,
as should engagement in care, ART adherence, HIV drug resistance, and quality-of-care
indicators. Reasons for regimen switching include virologic, immunologic, or clinical failure
and drug toxicity or intolerance. Confirmed treatment failure should be addressed
promptly and multiple factors considered.
Conclusion: New recommendations for HIV patient care include offering ART to all
patients regardless of CD4 cell count, changes in therapeutic options, and modifications
in the timing and choice of ART in the setting of opportunistic illnesses such as
cryptococcal disease and tuberculosis.
Thermally driven surface winds in the tropics
Publisher: name: Climate Impacts Group
Year: 1998

An integrated study is performed to examine the response of the atmosphere to a largescale, elevated heat source in the tropics. Special emphasis is placed on the surface winds in response to the heating.The vertical structure of the low-level atmospheric response to an elevated large-scale, low-frequency heat source in the tropics is first explored using the tidal approach. The projections of heating onto the meridional eigenfunctions on an equatorial beta-plane show that, at low frequencies, the forced response is mainly supported by the continuous modes with moderate large negative equivalent depth. The total response is vertically uniform below the heating in an atmosphere with only Newtonian cooling.To further investigate the thermally forced response in the presence of both thermal and momentum damping, the linearized equations are decomposed into a set of shallow water equations using the vertical eigenfunctions in a vertically semi-infinite domain. The results show that the three-dimensional structure of the forced response is closely tied to the vertical structure of the heating, and the forced signals driven by deep heating propagate faster in the horizontal than those driven by shallow heating.The zonal decay scale in a shallow water system is proportional to the inverse of the square root of the product of the Rayleigh friction rate and the Newtonian cooling rate. Hence, in both the Rayleigh-friction-dominant case and the Newtonian-cooling-dominant case, the solutions are essentially zonally uniform in a zonally cyclic domain. However, since the characteristic meridional scale, which is the equatorial radius of deformation multiplied by the fourth root of the Prandtl number, is very large for the Rayleigh-friction-dominant case, the forced response can extend far outside the heating latitudes. Contrast to that, in the Newtonian-cooling-dominant case, the characteristic meridional scale is very small and the forced response is confined to the heating latitudes.The vertical structure of thermally driven circulation is significantly affected by the nature of dissipation. Newtonian cooling homogenizes the atmospheric motion in the vertical, and a strong vertically uniform wind is found below the heating. When Rayleigh friction dominates, the circulation driven by the heat source is confined to the layer where the heat source is located.Finally, the numerical solutions from a primitive-equation model confirm the previous analytical results.
Markov model studies of the El Nino-Southern Oscillation
Publisher: name: Climate Impacts Group
Year: 1999

Aspects of the El Nino-Southern Oscillation are investigated using statistical models derived from observational data sets of surface and subsurface temperature in the tropical Pacific Ocean. Topics examined include: the existence of a seasonal cycle in the unforced internal dynamics of the sea surface temperature (SST) anomaly field; useful forecasting information contained in the subsurface temperature anomalies not reflected in SST; Geographical patterns of SST anomaly and subsurface temperature anomaly that lead to highest growth of SST anomaly in a given period of time.Annual variation in the Markov model is sought using various tests. It is determined with a high degree of certainty that the seasonal transition matrices are not season-interchangeable, indicating that the internal dynamics are not annually constant. A numerical model representation of ENSO should therefore include a seasonal cycle in the internal (unforced) dynamics. The forecast skill of a Markov model derived form SST anomalies alone is compared to the skill of a Markov model derived from surface plus subsurface temperature anomalies. The Markov model that includes the subsurface information possesses increased forecast skill at all lead times. The second principal component of heat content anomaly, which appears to contribute information on the transition phase between warm and cold ENSO events, is the primary contributor to the improvement in skill. The skill added by including subsurface information, although robust, is not shown to be statistically significant.The qualitative structure of the empirically derived optimal initial and final patterns of SST and subsurface temperature anomaly are found to be fairly robust. The optimal final pattern of both SST and heat content anomaly is identical to the respective fields during the peak of an ENSO event. Skill of forecasts of Nino indices using only the projection of the SST anomaly state onto the t -month SST optimal pattern nearly matches the skill of forecasts by the full empirically-derived model, which indicates that a sizeable fraction of ENSO forecast skill is captured by resolving the ENSO mode at the forecast start time.

description: We compare three analytical prescriptions for merger times available from the literature to simulations of isolated mergers. We probe three different redshifts, and several halo concentrations, mass ratios, orbital circularities and orbital energies of the satellite. We find that prescriptions available in the literature significantly under-predict long timescales for mergers at high redshift. We argue that these results have not been highlighted previously either because the evolution of halo concentration of satellite galaxies has been neglected (in previous isolated merger simulations), or because long merger times and mergers with high initial orbital circularities are under-represented (for prescriptions based on cosmological simulations). Motivated by the evolution of halo concentration at fixed mass, an explicit dependence on redshift added as t_merger,modified(z) = (1+z)^0.44 t_merger to the prescription based on isolated mergers gives a significant improvement in the predicted merger times up to ~20 t_dyn in the redshift range 0

Regional Climate and Hydrologic Change in the Northern U.S. Rockies and Pacific Northwest: Internally Consistent Projections of Future Climate for Resource Management
Publisher: name: Climate Impacts Group
Year: 2011

Planning for the effects of climate change on natural resources often requires detailed projections of future climate at finer spatial scales consistent with the processes managers typically consider. While it is numerically possible to produce downscaled climate at very fine scales (< 5km), accurate estimation at these scales is difficult and less certain without very detailed local information. Both the absence of a sufficiently dense network of long-term climate observations and the presence of local factors such as topography and land surface feedbacks from vegetation and snowpack contribute to the uncertainties of localized projections. To meet the needs of managers for developing adaptation strategies, vulnerability assessments, climate impacts assessments, and specific resource modeling at landscape scales, we downscaled projections from the coarser scales of global climate models (GCMs) to more local scales. The R1/R6 project was designed primarily to provide climate information consistent with manager requests and to create a basis for more detailed work or for a more comprehensive approach to downscaling and regional climate modeling. The objectives of this project were to: Develop consistent historical and future downscaled climate and hydrologic data and projections using the same methodology for several major river basins in the western United States, Columbia, upper Missouri, upper Colorado, and Great Basins, and Summarize that information with the needs of the funding agencies in mind, including descriptions of where to get the information, methods, results, uses of and uncertainties associated with the data and projections.
title: Déchets hospitaliers : peut-on réaliser des économies en « déclassant » certains Dasri en DADM ?

description: Né d’une collaboration entre l’équipe opérationnelle d’hygiène hospitalière (EOHH) et la direction du centre hospitalier (CH) de Cholet, le projet de diminuer le tonnage des déchets d’activités de soins à risque infectieux (Dasri) de ce CH s’appuie sur la réflexion d’un groupe de travail régional concernant le risque infectieux lié aux déchets. En accord avec la réglementation en vigueur, ce projet consiste à éliminer certains Dasri, pouvant comporter des liquides biologiques sans risque d’écoulement, vers la filière déchets assimilés aux déchets ménagers (DADM). Une cartographie des risques simplifiée du circuit DADM a été réalisée par l’EOHH, inspirée d’une analyse des modes de défaillance du circuit Dasri, de leurs effets, et de leur criticité. Puis, s’appuyant sur les conclusions du groupe de travail, une nouvelle règle de tri simple a été instaurée : en cas de risque d’écoulement de liquide biologique, l’évacuation en filière Dasri est nécessaire, sinon l’évacuation s’effectue vers la filière DADM. Afin de sécuriser le circuit DADM, un plan de maîtrise a proposé 12 actions correctives. Suite à la mise en place de cette nouvelle règle de tri en juin 2016 et à l’approche globale de la problématique des déchets toutes catégories confondues, le poste de dépense des DADM et Dasri a diminué de 144 000 euros entre 2015 et 2017. Ce projet est transposable à d’autres établissements de santé.
