Analyse de l’impact potentiel du mécanisme de règlement des différends entre les investisseurs et les États de l’Accord économique et commercial global sur l’environnement au Canada
Creators: name: Babou, Winnie
Publisher: name: My University
Year: 2016

description: Cette étude aborde la problématique du libre-échange à l’heure de la mondialisation. Plus précisément, elle s’intéresse à l’impact potentiel du mécanisme de règlement des différends entre investisseurs et États de l’AECG sur l’environnement. L’enjeu de cet accord est celui du mécanisme de règlement des différends qui pose le problème de la capacité des États signataires de réglementer et de poursuivre des objectifs légitimes de politique publique, incluant la protection de la santé, de la sécurité ou encore de l’environnement. Plusieurs auteurs soutiennent à ce sujet que le mécanisme de règlement des différends a une influence négative sur les États. Ces derniers disposent de moins en moins de marge de manoeuvre pour mener à bien leurs objectifs d’intérêt public lorsqu’ils sont soumis au mécanisme de règlement des différends entre investisseurs et États (en anglais, ISDS) et cela au profit des investisseurs étrangers. Les facteurs explicatifs exposés dans la littérature spécialisée – qui vont de la nature des relations entre les parties aux différents accords de libre-échange et d’investissement aux dispositions relatives au mécanisme ISDS – permettent de mieux cerner le contenu de l’AECG et de vérifier que la souveraineté des États est bien respectée en matière de politique publique de santé ou d’environnement. L’objectif de ce mémoire est le suivant : déterminer la place des considérations environnementales dans l’AECG afin de préserver la capacité des États parties à l’accord à mettre en place des politiques publiques dans ce domaine. Le mémoire défend l’idée que le mécanisme de règlement des différends soumettait par le passé les acteurs politiques à un défi, celui de maintenir la capacité des États à mettre en place des politiques publiques dans ce domaine sans toutefois brimer le droit des investisseurs étrangers. Aujourd’hui au contraire, les partenaires de l’AECG ont su éditer cet ordre juridique où les acteurs étatiques devront composer avec la réalité du changement climatique et valider le degré de leurs actions pour un développement plus durable. Pour ce faire, la recherche emprunte une démarche interprétative axée sur une analyse de la logique interne des textes entourant les dispositions du chapitre de l’investissement ainsi que celui de l’environnement de l’AECG. L’analyse révèle par conséquent une prise en compte sans précédent des considérations environnementales, mais qui pourrait toutefois être améliorée pour protéger davantage le droit des États à légiférer et réglementer en matière d’environnement. Elle indique cependant quelle pourrait être la meilleure approche à suivre pour adresser ces limites. MOTS CLÉS : ISDS, AECG, Investisseurs-États, environnement, politiques publiques,

description: We propose a practical and efficient method for adding security to network-attached disks (NADs). In contrast to previous work, our design requires no changes to the data layout on disk, minimal changes to existing NADs, and only small changes to the standard protocol for accessing remote block-based devices. Thus, existing NAD file systems and storage-management software could incorporate our scheme very easily. Our design enforces security using the well-known idea of self-describing capabilities, with two novel features that limit the need for memory on secure NADs: a scheme to manage revocations based on capability groups, and a replay-detection method using Bloom filters. We have implemented a prototype NAD file system, called Snapdragon, that incorporates our ideas. We evaluated Snapdragon's performance and scalability. The overhead of access control is small: latency for reads and writes increases by less than 0.5 ms (5%), while bandwidth decreases by up to 16%. The aggregate throughput scales linearly with the number of NADs (up to 7 in our experiments).

description: The scattering-matrix for planar Yang-Mills with N=4 supersymmetry relies on the assumption that integrability holds to all orders in perturbation theory. In this note we define a map from the spectral variables x^{\pm}, parameterizing the long-range magnon momenta, to couplings in a two-dimensional Ising model. Under this map integrability of planar N=4 Yang-Mills becomes equivalent to the Yang-Baxter equation for the two-dimensional Ising model, and the long-range variables x^{\pm} translate into the entries of the Ising transfer matrices. We explore the Ising correlation length which equals the inverse magnon momentum in the small momentum limit. The critical regime is thus reached for vanishing magnon momentum. We also discuss the meaning of the Kramers-Wannier duality transformation on the gauge theory, together with that of the Ising model critical points.

description: This study investigates the effects of higher dimensions on the observable properties of Schwarzschild-Tangherlini black holes, focusing on the photonsphere, shadow radius, deflection angles, and quasinormal modes (QNMs). By extending classical methods with Physics-Informed Neural Networks (PINNs), the research examines how increasing dimensionality alters these properties, causing shadow size reduction, weaker deflection angles, and shifts in QNM frequencies. The findings suggest that as black holes increase in dimensionality, their gravitational influence diminishes, particularly affecting light deflection and the stability of photon orbits. Through both weak and strong deflection analyses, this study indicates the need for ultrasensitive technology to detect these higher-dimensional signatures. Remarks on the observational data constraints currently favor four-dimensional spacetime; however, the exploration of additional dimensions remains vital in advancing models of quantum gravity. This work provides a theoretical framework for understanding black hole behavior in higher dimensions, potentially informing future astrophysical observations.

description: Using the Bardeen tunneling method with first-principles wave functions, computations are made of the tunneling current in graphene / hexagonal-boron-nitride / graphene (G/h-BN/G) vertical structures. Detailed comparison with prior experimental results is made, focusing on the magnitude of the achievable tunnel current. With inclusion of the effects of translational and rotational misalignment of the graphene and the h-BN, predicted currents are found to be about 15x larger than experimental values. A reduction in this discrepancy, to a factor of 2.5x, is achieved by utilizing a realistic size for the band gap of the h-BN, hence affecting the exponential decay constant for the tunneling.

description: Excerpt from the Preface: The scope of this bibliography is delineated in the table of contents. The section of comprehensive references on the pre-Columbian agriculture of the American Indian is of special interest to the general reader. The section on the centers of advanced agricultural development supplies references for the research worker who wishes to know about the methods used by the Indian in terrace farming, irrigation, conservation, and other evidences of progress beyond primitive cultivation. The section on the particular crops domesticated and raised by the Indian will, it is hoped, be helpful to the scientist in carrying on research incident to the history and improvement of these crops. The section on the agriculture of the reservations in the United States provides selected references on recent and present-day problems of irrigation, conservation, forestry, and land use. The sections on food and medicinal plants used by the Indian are of similar import for the scientist who seeks new sources of food and drugs. In view of the fact that the Indians constitute a large share of the populations of the New World countries other than the United States and Canada, the bibliography may also contribute to a better understanding of the culture of these countries and therefore to closer relations between North and South America.

description: We investigate the reflectionlessness and invisibility properties in the transverse electric (TE) mode solution of a linear homogeneous optical system which comprises the $\mathcal{PT}$-symmetric structures covered by graphene sheets. We derive analytic expressions, indicate roles of each parameter governing optical system with graphene and justify that optimal conditions of these parameters give rise to broadband and wide angle invisibility. Presence of graphene turns out to shift the invisible wavelength range and to reduce the required gain amount considerably, based on its chemical potential and temperature. We substantiate that our results yield broadband reflectionless and invisible configurations for realistic materials of small refractive indices, usually around $η= 1$, and of small thickness sizes with graphene sheets of rather small temperatures and chemical potentials. Finally, we demonstrate that pure $\mathcal{PT}$-symmetric graphene yields invisibility at small temperatures and chemical potentials.

description: Spherical harmonics are a favorable technique for 3D representation, employing a frequency-based approach through the spherical harmonic transform (SHT). Typically, SHT is performed using equiangular sampling grids. However, these grids are non-uniform on spherical surfaces and exhibit local anisotropy, a common limitation in existing spherical harmonic decomposition methods. This paper proposes a 3D representation method using Fibonacci Spherical Harmonics (FSH3D). We introduce a spherical Fibonacci grid (SFG), which is more uniform than equiangular grids for SHT in the frequency domain. Our method employs analytical weights for SHT on SFG, effectively assigning sampling errors to spherical harmonic degrees higher than the recovered band-limited function. This provides a novel solution for spherical harmonic transformation on non-equiangular grids. The key advantages of our FSH3D method include: 1) With the same number of sampling points, SFG captures more features without bias compared to equiangular grids; 2) The root mean square error of 32-degree spherical harmonic coefficients is reduced by approximately 34.6% for SFG compared to equiangular grids; and 3) FSH3D offers more stable frequency domain representations, especially for rotating functions. FSH3D enhances the stability of frequency domain representations under rotational transformations. Its application in 3D shape reconstruction and 3D shape classification results in more accurate and robust representations.

description: The experimental search for the chiral magnetic effect in heavy-ion collisions is based on charge dependent correlations between emitted particles. Recently, a sensitive observable comparing event-by-event distributions of the charge splitting projected on the directions along and perpendicular to the direction of the elliptic flow has been proposed. The results of a 3+1-dimensional hydrodynamic model show that the preliminary experimental data of the STAR Collaboration can be explained as due to background effects, such as resonance decays and local charge conservation in the particle production. A related observable based on the third order harmonic flow is proposed to further investigate such background effects in charge dependent correlations.

description: When it comes to the current debate on skills and employment in Canada, however, it may be the "unknown knowns" that are most important. We have oceans of reports and statistics but if their findings are not synthesized, research can't guide policy and won't tell new graduates much about the labour market of today, or how to prepare for the future. So what happened when 16 teams of researchers working across the country took a look at the existing research on skills and labour markets? Here is some of what they discovered: 1. Canada is unlikely to face a generalized shortage of skilled labour now or in the coming decades, despite an aging population and the changing skill requirements of many occupations. Our labour force continues to expand due in part to longer work lives, while important groups of workers (youth, aboriginal, persons with disabilities, skilled immigrants) are significantly "under-utilized" in the labour market. As in the past, future skills gaps are likely to be cyclical and focused on particular industries and regions.
A JOURNEY TO AUTHENTICITY: An Autoethnography of Compulsive Excoriation (Skin Picking) Disorder
Creators: name: Grodinsky, Allison Morin
Publisher: name: My University
Year: 2022

description: Compulsive excoriation (skin picking) disorder (CSPD) is an underrecognized mental illness that affects 2-5% of the population. This autoethnography aims to bridge the gap in qualitative research pertaining to CSPD. The research question asks: How can a deeper understanding of compulsive excoriation (skin picking) disorder be achieved through the exploration of a lived experience? The objectives were 1) to raise awareness, consolidate knowledge and disprove misconceptions about CSPD; 2) to embark on an emancipatory journey to authenticity; 3) to critically analyze the sociopolitical dynamics inherent in the experience of living with a mental illness in modern-day Western society. These objectives were achieved through the writing and subsequent analyzing of a chronological multilayered autoethnographic account of my lived experience with CSPD. The autoethnographic methodology provides unique access to a deeper understanding of the complexity and paradoxes intrinsic to the day-to-day circumstances of those with CSPD. Based on my analysis, two tables were created with a vision of generating awareness and contributing strategies. The first table can serve as a tool for those living with CSPD. The second table presents strategies for health professionals, loved ones and the public on how to support those living with CSPD. The sociopolitical influence of an immense pressure to succeed, beauty standards, the stigma of mental illness and the intricacies of obtaining mental health diagnoses were discussed in relation to their impact on individuals’ lived experience of CSPD.

description: How to make a model of a non-Fermi-liquid metal with efficient current dissipation is a long-standing problem. Results from holographic duality suggest a framework where local critical fermionic degrees of freedom provide both a source of decoherence for the Landau quasiparticle, and a sink for its momentum. This leads us to study a Kondo lattice type model with SYK models in place of the spin impurities. We find evidence for a stable phase at intermediate couplings.

description: The subject of time-band-limiting, originating in signal processing, is dominated by the miracle that a naturally appearing integral operator admits a commuting differential one allowing for a numerically efficient way to compute its eigenfunctions. Bispectrality is an effort to dig into the reasons behind this miracle and goes back to joint work with H. Duistermaat. This search has revealed unexpected connections with several parts of mathematics, including integrable systems. Here we consider a matrix valued version of bispectrality and give a general condition under which we can display a constructive and simple way to obtain the commuting differential operator. Furthermore, we build an operator that commutes with both the time-limiting operator and the band-limiting operators.

description: We present a concise review of the physics of ultra-cold dipolar gases, based mainly on the theoretical developments in our own group. First, we discuss shortly weakly interacting ultra-cold trapped dipolar gases. Dipolar Bose-Einstein condensates exhibit non-standard instabilities and the physics of both Bose and Fermi dipolar gases depends on the trap geometry. We focus then the second part of the paper on strongly correlated dipolar gases and discuss ultra-cold dipolar gases in optical lattices. Such gases exhibit a spectacular richness of quantum phases and metastable states, which may perhaps be used as quantum memories. We comment shortly on the possibility of superchemistry aiming at the creation of dipolar heteronuclear molecules in lattices. Finally, we turn to ultra-cold dipolar gases in artificial magnetic fields, and consider rotating dipolar gases, that provide in our opinion the best option towards the realization of the fractional quantum Hall effect and quantum Wigner crystals.

description: In these notes we review and further explore the Lie enveloping algebra of a post-Lie algebra. From a Hopf algebra point of view, one of the central results, which will be recalled in detail, is the existence of a second Hopf algebra structure. By comparing group-like elements in suitable completions of these two Hopf algebras, we derive a particular map which we dub post-Lie Magnus expansion. These results are then considered in the case of Semenov-Tian-Shansky's double Lie algebra, where a post-Lie algebra is defined in terms of solutions of modified classical Yang-Baxter equation. In this context, we prove a factorization theorem for group-like elements. An explicit exponential solution of the corresponding Lie bracket flow is presented, which is based on the aforementioned post-Lie Magnus expansion.

description: Ru has been considered a candidate to replace Cu-based interconnects in VLSI circuits. Here, a methodology is proposed to predict the resistivity of (Ru) interconnects. First, the dependence of the Ru thin film resistivity on the film thickness is modeled by the semiclassical Mayadas-Shatzkes (MS) approach. The fitting parameters thus obtained are then used as input in a modified MS model for nanowires to calculate wire resistivities. Predicted experimental resistivities agreed within about 10%. The results further indicate that grain boundary scattering was the dominant scattering mechanism in scaled Ru interconnects.

The properties are expressed using a variation of PCTL, the Probabilistic Computation Tree Logic. We present a general model of stochastic discrete event systems, which encompasses both discrete-time and continuous-time processes, and we provide a semantics for PCTL interpreted over this model. Our presentation is both a generalization of and an improvement over some recent work by Sen et al. on probabilistic verification of 'black-box' systems."

description: We discuss some of the key open questions regarding the formation and evolution of globular clusters (GCs) during galaxy formation and assembly within a cosmological framework. The current state-of-the-art for both observations and simulations is described, and we briefly mention directions for future research. The oldest GCs have ages $\ge$ 12.5 Gyr and formed around the time of reionisation. Resolved colour-magnitude diagrams of Milky Way GCs and direct imaging of lensed proto-GCs at z $\sim$ 6 with JWST promise further insight. Globular clusters are known to host multiple populations of stars with variations in their chemical abundances. Recently, such multiple populations have been detected in $\sim$2 Gyr old compact, massive star clusters. This suggests a common, single pathway for the formation of GCs at high and low redshift. The shape of the initial mass function for GCs remains unknown, however for massive galaxies a power-law mass function is favoured. Significant progress has been made recently modelling GC formation in the context of galaxy formation, with success in reproducing many of the observed GC-galaxy scaling relations.

description: We study non-Markovianity in the exact dynamics of two two-level atoms in a resonant cavity. We find a critical behavior in the form of a Markovian to non-Markovian transition at a finite interatomic distance and a discontinuity in the limit of infinitely close atoms. Actually, in this highly correlated regime, we find that non-Markovianity always arises if the system size exceeds a critical threshold. To this end, a non-singular, additive non-Markovian measure with appropriate asymptotic behavior is formulated. These results show how inter-subsystem distance and system size can act as precise controls for modulating memory effects in multipartite open quantum systems.

Pandémie, médias sociaux et influenceurs : Implications pour la santé mentale des adolescentes
Creators: name: Ngemba, Mwana Samba Sybelle-Tanya

Year: 2023

description: Dans la société moderne, on constate que les médias sociaux sont devenus des outils incontournables dans le quotidien de la jeunesse et cela sur différentes facettes de leur vie. En effet, les réseaux sociaux semblent, aujourd’hui, jouer un rôle non négligeable dans l’éducation des jeunes dans leur parcours de construction identitaire, depuis les années 2000. Au Canada, l’arrivée de la pandémie COVID-19 a été favorable à la surutilisation d’Internet dans les foyers. En effet, l’exposition et le dévoilement de soi sur les réseaux sociaux à travers l’imitation des différents modèles qu’on y trouve ont pris des proportions importantes, principalement chez les jeunes filles qui sont identifiées comme étant la population la plus à risque d’en subir les conséquences négatives. De plus, ce phénomène apparait aujourd’hui chez les chercheurs comme un souci d’être qui va au-delà du paraitre. L’influence des technologies numériques sur les adolescentes durant le confinement demeure un sujet peu abordé dans la littérature scientifique. La présente recherche théorique permet de comprendre comment et en quoi cette culture numérique façonne et modifie l’identité des adolescentes, en plus d’influencer sur le développement de l’estime de soi, des troubles alimentaires et des troubles de l’image corporelle. C’est la raison pour laquelle ce mémoire s’intéresse à la question suivante : en temps de pandémie et de confinement, quels rôles la surutilisation des réseaux sociaux et l’exposition aux influenceurs ont-ils joués sur le bien-être mental des adolescentes? Ainsi, les cadres théoriques des comparaisons sociales (Festinger, 1954) et des relations parasociales (Horton et Wohl,1956) ont été mobilisés afin de mieux situer l’influence de ce phénomène et de son rôle sur la jeunesse. Méthodologiquement, cette recherche s’inscrit dans une approche qualitative à caractère inductif. L’analyse thématique d’un large corpus d’écrits a permis de mettre en lumière trois facteurs qui ont joué un rôle significatif dans le maintien d’un mauvais état de bien-être mental chez les adolescentes à savoir : 1) la mise en place du confinement, 2) la présence et la notoriété des influenceurs sur les réseaux sociaux, ainsi que 3) l’apparition de différents enjeux de surutilisation des médias sociaux.

description: Objective: To quantify food/beverage advertising on television in Montreal (Quebec), to estimate and characterize children’s exposure and to examine trends over time. Design: Television food advertising data were licensed for nineteen food categories and eighteen stations for May 2011, 2016 and 2019. The frequency of advertisements and the average number viewed per child aged 2–11 years overall, by food category and by station type (i.e. youth-appealing (n 3) and generalist (n 15) stations) were determined. The percent change in advertising frequency and exposure between May 2011 and 2019 was calculated. Setting: Montreal, Quebec, Canada. Participants: This study used media data and did not directly involve human participants. Results: The total number of television advertisements increased by 11 % between May 2011 (n 41 084) and May 2019 (n 45 406); however, exposure to food/beverage advertisements decreased by 53 %, going from 226 ads/child in May 2011 to 107 ads/child in May 2019. Overall, the most advertised food categories in both May 2011 and 2019 were fast food (29·8 % and 39·2 %, respectively) followed by chocolate (14·2 %) in 2011 and savory snacks (9·7 %) in 2019. In May 2019, children were predominantly exposed to unhealthy food categories such as fast food (41·3 % of exposure), savory snacks (7·5 %), chocolate (5·0 %) and regular soft drinks (4·5 %), and most (89·3 %) of their total exposure occurred on generalist television stations. Conclusion: Despite Quebec’s restrictions on commercial advertising directed to children under 13 years, Quebecois children are still frequently exposed to unhealthy food advertising on television. Government should tighten restrictions to protect children from this exposure.
Expansion schemes for gravitational clustering: computing two-point and three-point functions

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We describe various expansion schemes that can be used to study gravitational clustering. Obtained from the equations of motion or their path-integral formulation, they provide several perturbative expansions that are organized in different fashion or involve different partial resummations. We focus on the two-point and three-point correlation functions, but these methods also apply to all higher-order correlation and response functions. We present the general formalism, which holds for the gravitational dynamics as well as for similar models, such as the Zeldovich dynamics, that obey similar hydrodynamical equations of motion with a quadratic nonlinearity. We give our explicit analytical results up to one-loop order for the simpler Zeldovich dynamics. For the gravitational dynamics, we compare our one-loop numerical results with numerical simulations. We check that the standard perturbation theory is recovered from the path integral by expanding over Feynman's diagrams. However, the latter expansion is organized in a different fashion and it contains some UV divergences that cancel out as we sum all diagrams of a given order. Resummation schemes modify the scaling of tree and one-loop diagrams, which exhibit the same scaling over the linear power spectrum (contrary to the standard expansion). However, they do not significantly improve over standard perturbation theory for the bispectrum, unless one uses accurate two-point functions (e.g. a fit to the nonlinear power spectrum from simulations). Extending the range of validity to smaller scales, to reach the range described by phenomenological models, seems to require at least two-loop diagrams.

description: Donor spins in silicon are some of the most promising qubits for upcoming solid-state quantum technologies. The nuclear spins of phosphorus donors in enriched silicon have among the longest coherence times of any solid-state system as well as simultaneous qubit initialization, manipulation and readout fidelities near ~99.9%. Here we characterize the phosphorus in silicon system in the regime of "zero" magnetic field, where a singlet-triplet spin clock transition can be accessed, using laser spectroscopy and magnetic resonance methods. We show the system can be optically hyperpolarized and has ~10 s Hahn echo coherence times, even at Earth's magnetic field and below.

description: Purpose: This paper describes women's opinions of the attributes of the ideal body image program to inform the design, development, and implementation of future programs for those diagnosed with breast cancer. Methods: Deductive-inductive content analysis of semi-structured interviews with 26 women diagnosed with breast cancer (mean age = 55.96 years; mean time since diagnosis = 2.79 years) was performed. Findings: Participants' opinions regarding the ideal body image program are summarized into five themes, mapping the where (community-based, hospital-based, or online), when (across the cancer continuum or at specific points), how (peer-led programs, professional help, events, presentations/workshops, resources, support groups), what (self-care, counseling and education for one self, education for others, support for addressing sexuality/sexual health concerns, and concealing treatment-related changes), and who (team approach or delivered by women, health professionals, make-up artists). Conclusion: This study provides useful data on what women believe are the attributes of the ideal body image program, which can contribute to efforts aimed at developing and delivering body image programs for women diagnosed with breast cancer that prioritize their needs and preferences.

description: We combine the gravitational-wave measurement of the effective distance to the binary neutron star merger GW170817, the redshift of its host galaxy NGC 4993, and the latest Hubble constant measurement from the Dark Energy Survey to constrain the inclination between the orbital angular momentum of the binary and the line of sight to $18 \pm 8$ degrees (less than 28 degrees at 90% confidence). This provides a complementary constraint on models of potential afterglow observations.

Subjects: Land Economics/Use

description: Excerpts from the Introduction: This bibliography has been compiled as a companion volume to the Bibliography on Land Settlement, issued in 1934 by the United States Department of Agriculture as Miscellaneous Publication 172. It contains selected references to the literature on the economic aspects of land utilization and land policy in the United States and in foreign countries, published for the most part during the period 1918-36. Relatively few references to the early land policies of the United States and of the individual States have been included, mainly because a bibliography on this subject is in preparation by the Bureau of Agricultural Economics. In the case of foreign countries a greater number of references have been included to material which antedates 1918, because they provide what seems to be an essential background to the more modern literature on the subject. The bibliography is limited to references on land utilization in its broader economic aspects; and much of the literature on special phases of the subject, such as farm management, urban land uses, etc., has been omitted. Only a few references on such subjects as soils and soil erosion, forest shelterbelts, general economic planning, regional planning, and forests and afforestation have been included. Many references to land settlement and resettlement, subsistence homesteads, and agrarian reform are included to supplement those contained in the earlier Bibliography on Land Settlement.

description: A single-arm feasibility trial was conducted to explore rural-living young adult cancer survivors' physical activity, fruit and vegetable consumption, and motivational processes underlying any behavior changes during a telehealth behavior change intervention grounded in self-determination theory. Participants (n = 7; 85.7% female; Mage = 33.9, range = 28-37) met with a health coach once a week for 60 min for 12 weeks. Participants completed pre- and post-intervention surveys that assessed their behaviors, basic psychological needs satisfaction, and behavioral regulations. Participants also completed a semi-structured interview post-intervention. Quantitative results indicate behavioral outcomes, basic psychological needs satisfaction, and behavioral regulations increased from pre- to post-intervention. Five themes provide context for the observed increases. Results provide preliminary evidence that motivation for physical activity and fruit and vegetable consumption may be facilitated by a one-on-one telehealth intervention among rural-living young adult cancer survivors. Large scale studies are needed to determine effectiveness of the intervention and identify mechanisms underpinning behavioral outcomes.

description: We present a compiler algorithm called Bit Value, which can discover both unused and constant bits in dusty-deck C programs. Bit-Value uses forward and backward dataflow analyses, generalizing constant-folding and dead-code detection at the bit-level. This algorithm enables compiler optimizations which target special processor architectures for computing on non-standard bitwidths. Using this algorithm we show that up to 31% of the computed bytes are thrown away (for programs from SpecINT95 and Mediabench). A compiler for reconfigurable hardware uses this algorithm to achieve substantial reductions (up to 20-fold) in the size of the synthesized circuits.

description: The dynamics of processes of antimony desorption was investigated on the singular and vicinal GaSb(001) surface by RHEED method. The role of the terraces edges was determined during antimony evaporation in Langmuir desorption mode. It is shown that the structural transition (2x5) -> (1x3) is a complex of two transitions - order -> disorder and disorder -> order. The influence of the degree of surface miscut from the singular face on the dimension of the transition (2x5) -> DO was studied. The activation energies of structural transitions ex(2x5) -> (2x5), (2x5) -> DO and DO -> (1x3) on singular and vicinal faces GaSb(001) were determined.

Deliverable No. 5.2 Strengths and limitations of state-of-the-art weather and climate prediction systems

description: This document provides an overview of predictive capacity over the Arctic and mid- latitudes of current state-of-the-art prediction systems ranging from numerical weather prediction (NWP) to seasonal time scales. The assessment is mainly based on forecasting systems and climate models contributing to the APPLICATE project. This deliverable therefore provides a thorough evaluation of the forecast models included in the WP5 stream 1 experiments, and a baseline for future improvements to current systems resulting from developments in the framework of the project. Beyond commonly used verification metrics for the evaluation of weather and climate predictions, illustrations of current systems predictive capacity are shown by focusing on specific phenomena and case studies (e.g. extreme rainfall on Svalbard). With the perspective of providing useful and reliable forecasts for potential end-users, some skill evaluations on more user-relevant metrics were included. Results on the weather prediction time scales show the impact of horizontal resolution in better representing precipitation extremes, although some weaknesses remain in a 2.5 km resolution configuration for the Svalbard case study examined in this deliverable. More generally, high resolution limited area models show added value with respect to global models depending on the parameter and region of interest. At the medium range (5 days), the evaluation of the European Centre for Medium- range Weather Forecasts (ECMWF) forecasts over 1990-present for geopotential height at 500 hPa shows that these have been steadily improving over the Arctic, at the same rate as the Northern Hemisphere in general. Skill and biases are found to vary according to the region and season of interest. Seasonal re-forecasts over a common 1993-2014 period were evaluated for both atmospheric and sea ice concentration fields. The skill of the systems is quite limited, consistent with previous works. For sea ice, forecast performance for boreal summer seems to depend quite strongly on systematic errors which appear in some systems from the initialization time step. This deliverable also presents results from a statistical forecasting framework, using HighResMIP model simulations to evaluate lagged predictability of sea ice volume with sea ice volume and area as predictors. It appears from the results presented that sea ice area does not add much additional predictability to the information provided by sea ice volume.
