Year: 2021

description: Pandemia COVID-19 już od ponad roku kształtuje codzienność w wymiarach globalnym i lokalnym. Wpływ pandemii na określone fragmenty rzeczywistości, w tym funkcjonowanie wszystkich grup wiekowych, społecznych, zawodowych i innych, jest coraz silniejszy. Coraz więcej osób potrzebuje zróżnicowanych form pomocy i wsparcia. W tekście zaprezentowano wyniki pilotażowych badań dotyczących funkcjonowania wolontariuszy oraz organizacji i instytucji społecznych. Szczególna uwaga skupiona jest na ludziach i ich pracy w czasie pandemii, na wskazane trudności i sposoby przełamywania lęku przed wspieraniem drugiego człowieka w wyjątkowej sytuacji. Omawiam też możliwości rozwoju idei pracy wspierającej drugiego człowieka, oparte na codziennej solidarności i zmieniającej dotychczasowy styl wolontariatu.

description: A careful functional treatment of quantum scattering is given using Schwinger's dynamical principle which involves a functional differentiation operation applied to a generating functional written in closed form. For long range interactions, such as for the Coulomb one, it is shown that this expression may be used to obtain explicitly the asymptotic "free" modified Green function near the energy shell.

description: Globalizacja jest procesem wpływającym na każdą sferę życia społecznego, a także życia osobistego. Szczególną ewolucję można zaobserwować w obszarze pracy i edukacji, które przeszły wiele zmian pod wpływem czynników globalizacji. Edukacja jest tą gałęzią, która w ogromnym stopniu pokazuje obraz i funkcjonowanie innych gałęzi życia społecznego. Proces edukacji w dobie globalizacji znacznie różni się od dotychczas funkcjonującego systemu edukacji. W dobie globalizacji edukacja staje się procesem trwającym przez całe życie, wykorzystującym do swego przekazu najnowsze osiągnięcia techniczne i technologiczne. Dzięki temu rynek edukacji, a co się z tym wiąże, rynek pracy w najbliższej przyszłości mogą stać się najszybciej rozwijającymi się rynkami. Rozwój naszego kraju i jego konkurencyjność oparte są na edukacji i poziomie nauczyciela. Procesy globalizacji wymagają przygotowywania nowego, innego obywatela, który będzie mógł przystosować się do społecznych, kulturalnych i ekonomicznych przemian. Nie żyjemy w próżni, od nowoczesnej edukacji wymaga się, aby przygotowała człowieka, który będzie obywatelem świata, nie tylko Europy. Globalizacja zmusza ludzi nie tylko do rozszerzenia posiadanych kompetencji, lecz także do tego, aby stali się bardziej odporni na zmiany i życie w niepewności.

description: The thermal spin-wave distribution in a Ni81Fe19 stripe with an asymmetric transverse domain wall has been investigated using Brillouin light scattering microscopy. Clear evidence has been found that the existence of the domain wall influences the spin-wave distribution of the thermal modes. The thermal spin-wave modes are quantized due to the confinement in radial direction. They vanish near the domain wall and a new mode evolves inside this complex domain wall structure. This effect is attributed to a change of the effective internal field in the domain wall region. The experimental results agree well with static and dynamic micromagnetic simulations.

description: We present ${\tt nimbus}$ : a hierarchical Bayesian framework to infer the intrinsic luminosity parameters of kilonovae (KNe) associated with gravitational-wave (GW) events, based purely on non-detections. This framework makes use of GW 3-D distance information and electromagnetic upper limits from multiple surveys for multiple events, and self-consistently accounts for finite sky-coverage and probability of astrophysical origin. The framework is agnostic to the brightness evolution assumed and can account for multiple electromagnetic passbands simultaneously. Our analyses highlight the importance of accounting for model selection effects, especially in the context of non-detections. We show our methodology using a simple, two-parameter linear brightness model, taking the follow-up of GW190425 with the Zwicky Transient Facility (ZTF) as a single-event test case for two different prior choices of model parameters -- (i) uniform/uninformative priors and (ii) astrophysical priors based on surrogate models of Monte Carlo radiative transfer simulations of KNe. We present results under the assumption that the KN is within the searched region to demonstrate functionality and the importance of prior choice. Our results show consistency with ${\tt simsurvey}$ -- an astronomical survey simulation tool used previously in the literature to constrain the population of KNe. While our results based on uniform priors strongly constrain the parameter space, those based on astrophysical priors are largely uninformative, highlighting the need for deeper constraints. Future studies with multiple events having electromagnetic follow-up from multiple surveys should make it possible to constrain the KN population further.

description: We combine Bethe Ansatz and field theory methods to study the longitudinal dynamical structure factor S^{zz}(q,omega) for the anisotropic spin-1/2 chain in the gapless regime. Using bosonization, we derive a low energy effective model, including the leading irrelevant operators (band curvature terms) which account for boson decay processes. The coupling constants of the effective model for finite anisotropy and finite magnetic field are determined exactly by comparison with corrections to thermodynamic quantities calculated by Bethe Ansatz. We show that a good approximation for the shape of the on-shell peak of S^{zz}(q,omega) in the interacting case is obtained by rescaling the result for free fermions by certain coefficients extracted from the effective Hamiltonian. In particular, the width of the on-shell peak is argued to scale like delta omega_{q} ~ q^2 and this prediction is shown to agree with the width of the two-particle continuum at finite fields calculated from the Bethe Ansatz equations. An exception to the q^2 scaling is found at finite field and large anisotropy parameter (near the isotropic point). We also present the calculation of the high-frequency tail of S^{zz}(q,ω) in the region delta omega_{q}<< omega-vq << J using finite-order perturbation theory in the band curvature terms. Both the width of the on-shell peak and the high-frequency tail are compared with S^{zz}(q,omega) calculated by Bethe Ansatz for finite chains using determinant expressions for the form factors and excellent agreement is obtained. Finally, the accuracy of the form factors is checked against the exact first moment sum rule and the static structure factor calculated by Density Matrix Renormalization Group (DMRG).

Defining the Gothic in Italy : the Cistercians of San Galgano and civic architecture in Siena 1250-1350

description: The art and architecture of late medieval Siena is often described as "Gothic", especially vis-a-vis Florence; yet the issue of "what is Gothic" remains sparsely examined in Sienese architecture. For instance, the long tradition of nationalistic scholarship has preempted inquiry into the relationship between the nearby Cistercian abbey of San Galgano and stylistic developments in Sienese architecture, both ecclesiastic and civic. It is in civic architecture that the imprint of Cistercian forms can most clearly be recognized in Siena, and thus I focus on the relationship between San Galgano, the communal government of Siena, and the resultant architectural interchanges. I explore the connection between Burgundian forms and a nascent civic aesthetic, and I investigate why the city of Siena chose to turn to a foreign-derived, rurally-based order of monks for architectural guidance. I suggest that a grafting of local building practices and Cistercian style took place at the abbey of San Galgano, in effect translating Burgundian principles of design into a native idiom. A similar translation occurred when the regionally informed Cistercian architecture of San Galgano was transformed into Sienese civic structures, during the late thirteenth and early fourteenth centuries. The clearest evidence of this transformation occurs in the communal water sources or fonti. The fonti--built in the heyday of Siena's political power, in the latter half of the Duecento--in turn may have provided a model for future civic construction. Many of these projects were seemingly supervised by the monks of San Galgano, who had taken on key roles within Siena's government. What had occurred with the Cistercians in their monastic communities was a translation of an ecclesiastic style--the Gothic--into something more institutional and utilitarian. The Sienese may have perceived the functional, modular, and visually unifying potentialities inherent in Cistercian architecture, qualities that could easily be merged into the local idiom. I suggest that the architectural possibilities of the Burgundian form of the Gothic were amply evident to the Sienese, and that Cistercian principles of design were incorporated, far more than has previously been discussed, throughout the architectural fabric of medieval Siena
Calabi-Bernstein results for maximal surfaces in Lorentzian product spaces

description: In this paper we establish new Calabi-Bernstein results for maximal surfaces immersed into a Lorentzian product space of the form $M^2\times\mathbb{R}_1$, where $M^2$ is a connected Riemannian surface and $M^2\times\mathbb{R}_1$ is endowed with the Lorentzian metric $=_{M}-dt^2$. In particular, when $M$ is a Riemannian surface with non-negative Gaussian curvature $K_M$, we prove that any complete maximal surface in $M^2\times\mathbb{R}_1$ must be totally geodesic. Besides, if $M$ is non-flat we conclude that it must be a slice $M\times\{t_0\}$, $t_0\in\mathbb{R}$ (here by "complete" it is meant, as usual, that the induced Riemannian metric on the maximal surface from the ambient Lorentzian metric is complete). We prove that the same happens if the maximal surface is complete with respect to the metric induced from the Riemannian product $M^2\times\mathbb{R}$. This allows us to give also a non-parametric version of the Calabi-Bernstein theorem for entire maximal graphs in $M^2\times\mathbb{R}_1$, under the same assumptions on $K_M$. Moreover, we also construct counterexamples which show that our Calabi-Bernstein results are no longer true without the hypothesis $K_M\geq 0$. These examples are constructed via a duality result between minimal and maximal graphs.

description: We present a broadband map of polarized diffuse emission at 167-198 MHz developed from data from the Murchison Widefield Array (MWA). The map is designed to improve visibility simulation and precision calibration for 21 cm Epoch of Reionization (EoR) experiments. It covers a large swath - 11,000 sq. deg. - of the Southern Hemisphere sky in all four Stokes parameters and captures emission on angular scales of 1 to 9 degrees. The band-averaged diffuse structure is predominantly unpolarized but has significant linearly polarized structure near RA = 0 h. We evaluate the accuracy of the map by combining it with the GLEAM catalog and simulating an observation from the MWA, demonstrating that the accuracy of the short baselines (6.1-50 wavelengths) now approaches the accuracy of the longer baselines typically used for EoR calibration. We discuss how to use the map for visibility simulation for a variety of interferometric arrays. The map has potential to improve calibration accuracy for experiments such as the Hydrogen Epoch of Reionization Array (HERA) and the forthcoming Square Kilometre Array (SKA) as well as the MWA.

description: Heavy fermion compounds exhibiting a ferromagnetic quantum critical point have attracted considerable interest. Common to two known cases, i.e., CeRh$_6$Ge$_4$ and YbNi$_4$P$_2$, is that the 4f moments reside along chains with a large inter-chain distance, exhibiting strong magnetic anisotropy that was proposed to be vital for the ferromagnetic quantum criticality. Here we report an angle-resolved photoemission study on CeRh6Ge4, where we observe sharp momentum-dependent 4f bands and clear bending of the conduction bands near the Fermi level, indicating considerable hybridization between conduction and 4f electrons. The extracted hybridization strength is anisotropic in momentum space and is obviously stronger along the Ce chain direction. The hybridized 4f bands persist up to high temperatures, and the evolution of their intensity shows clear band dependence. Our results provide spectroscopic evidence for anisotropic hybridization between conduction and 4f electrons in CeRh$_6$Ge$_4$, which could be important for understanding the electronic origin of the ferromagnetic quantum criticality.
The use of headings and text organization as aids to recall of expository prose in grade 5 through 10 with an emphasis on grades 9 and 10

Publisher: name: University of British Columbia

description: This study investigated the effects of headings and text organization on grade 5 through 10 students' written recall of expository prose passages written in a classification/description mode. Emphasis was placed on the results from students in grades 9 and 10. This study was a component of a three part study. The other two parallel studies emphasized grades 5 and 6 (Stables, 1985) and 7 and 8 (King, 1985). Each subject read and recalled two passages: one written at his or her grade level and one written at a low readability level. Performance on the written recalls from passages with headings and without headings was examined on the basis of the number of superordinate and subordinate ideas recalled, the superordinate and subordinate organization, and the format. Developmental trends were investigated by including the data from the two parallel studies (Stables, 1985; King, 1985). There was some evidence that headings had a significant effect on the number of superordinate ideas recalled from a passage of low readability. Some significant differences indicated negative effects by headings. The majority of differences, however, were not significant. Developmental trends in grades 5 through 10 were noted in the number of ideas recalled on a low readability passage and the format used on the written recalls. Implications for instruction and suggestions for further research are discussed.

description: Artificial intelligence (AI) techniques for image-based segmentation have garnered much attention in recent years. Convolutional neural networks (CNNs) have shown impressive results and potential towards fully automated segmentation in medical imaging, and particularly PET imaging. To cope with the limited access to annotated data needed in supervised AI methods, given tedious and prone-to-error manual delineations, semi-supervised and unsupervised AI techniques have also been explored for segmentation of tumors or normal organs in single and bi-modality scans. This work provides a review of existing AI techniques for segmentation tasks and the evaluation criteria for translational AI-based segmentation efforts towards routine adoption in clinical workflows.

Najważniejsze jest dobro dziecka, czyli władza rodzicielska przed i po rozwodzie

description: Celem podjętego tematu było wyjaśnienie terminów: władza rodzicielska, rozwód, małżeństwo. Po przeprowadzonej analizie tych pojęć autorka skupiła swoją uwagę na wpływie rozwodu i rozstania rodziców na psychikę i społeczne funkcjonowanie dziecka. Rozwód to zjawisko coraz częściej spotykane w polskim społeczeństwie, władza rodzicielska po rozwodzie nadal przysługuje obojgu rodzicom. Sąd przy orzekaniu rozwodu oraz ustalaniu władzy rodzicielskiej kieruje się przede wszystkim nadrzędnym dobrem dziecka. Powstaje pytanie: jak na ten proces reaguje dziecko, jakie skutki zachodzą w jego psychice, a w efekcie w jego społecznym funkcjonowaniu? Dziecko na każdym etapie swojego rozwoju, począwszy od narodzin do okresu dojrzewania, w różny sposób przeżywa rozstanie rodziców. Bardzo często obwinia siebie za rozpad rodziny, staje się agresywne wobec kolegów i koleżanek. Rozwód doprowadza do zaburzenia funkcjonowania dziecka w społeczeństwie, m.in. poprzez opóźnienie w nauce, nadużywanie środków odurzajacych, psychoaktywnych. Na skutek rozwodu rodziców ma zaburzone wzorce związku, co często skutkuje problemami w założeniu przez niego swojej własnej rodziny i prawidłowym jej funkcjonowaniu.

description: The generalized traveling salesman problem (GTSP) is an extension of the well-known traveling salesman problem. In GTSP, we are given a partition of cities into groups and we are required to find a minimum length tour that includes exactly one city from each group. The aim of this paper is to present a problem reduction algorithm that deletes redundant vertices and edges, preserving the optimal solution. The algorithm's running time is O(N^3) in the worst case, but it is significantly faster in practice. The algorithm has reduced the problem size by 15-20% on average in our experiments and this has decreased the solution time by 10-60% for each of the considered solvers.

description: HIP 41378 f is a temperate $9.2\pm0.1 R_{\oplus}$ planet with period of 542.08 days and an extremely low density of $0.09\pm0.02$ g cm$^{-3}$. It transits the bright star HIP 41378 (V=8.93), making it an exciting target for atmospheric characterization including transmission spectroscopy. HIP 41378 was monitored photometrically between the dates of 2019 November 19 and November 28. We detected a transit of HIP 41378 f with NGTS, just the third transit ever detected for this planet, which confirms the orbital period. This is also the first ground-based detection of a transit of HIP 41378 f. Additional ground-based photometry was also obtained and used to constrain the time of the transit. The transit was measured to occur 1.50 hours earlier than predicted. We use an analytic transit timing variation (TTV) model to show the observed TTV can be explained by interactions between HIP 41378 e and HIP 41378 f. Using our TTV model, we predict the epochs of future transits of HIP 41378 f, with derived transit centres of T$_{C,4} = 2459355.087^{+0.031}_{-0.022}$ (May 2021) and T$_{C,5} = 2459897.078^{+0.114}_{-0.060}$ (Nov 2022).

The acquisition of the English system of pronominalization by adult second language learners
Creators: name: Takagaki, Bob
Publisher: name: University of British Columbia
Year: 2010

description: The study presented in this paper is a second language study of the acquisition of the English system of pronominalization by adult learners of English. It is a partial replication of Ingram and Shaw's (1981) first language acquisition study on the same topic. One hundred and eighty four subjects and twenty control subjects were administered a written task that involved making anaphoric assignments to pronouns in thirty five test sentences, representing seven different sentence construction types. Analysis of the data indicated that the two syntactic constraints of precedence and dominance played major roles in the anaphoric assignments made by all subjects. In addition, these two syntactic constraints were instrumental in delineating developmental stages in the acquisition process. A comparison of the response patterns displayed by the present study's subjects and those displayed by Ingram, and Shaw's subjects revealed a number of differences. These differences suggested that the acquisition process was not invariant and highly sequential in nature, but dynamic and highly creative, allowing a great deal of latitude in terms of the processing strategies employed.

description: Low dimensional ferroelectrics are highly desired for applications and full of exotic physics. Here a functionalized MXene Hf$_2$CF$_2$ monolayer is theoretically studied, which manifests a nonpolar to polar transition upon moderate biaxial compressive strain. Accompanying this structural transition, a metal-semiconductor transition occurs. The in-plane shift of unilateral fluorine layer leads to a polarization pointing out-of-plane. Such ferroelectricity is unconventional, similar to the recently-proposed interlayer-sliding ferroelectricity but not identical. Due to its specific hexapetalous potential energy profile, the possible ferroelectric switching paths and domain walls are nontrivial, which are mediated via the metallic paraelectric state. In this sense, the metallic walls can be manipulated by reshaping the ferroelectric domains.

description: A non-perturbative formalism is developed that simplifies the understanding of self-forces and self-torques acting on extended scalar charges in curved spacetimes. Laws of motion are locally derived using momenta generated by a set of generalized Killing fields. Self-interactions that may be interpreted as arising from the details of a body's internal structure are shown to have very simple geometric and physical interpretations. Certain modifications to the usual definition for a center-of-mass are identified that significantly simplify the motions of charges with strong self-fields. A derivation is also provided for a generalized form of the Detweiler-Whiting axiom that pointlike charges should react only to the so-called regular component of their self-field. Standard results are shown to be recovered for sufficiently small charge distributions.

A topos for algebraic quantum theory

description: The aim of this paper is to relate algebraic quantum mechanics to topos theory, so as to construct new foundations for quantum logic and quantum spaces. Motivated by Bohr's idea that the empirical content of quantum physics is accessible only through classical physics, we show how a C*-algebra of observables A induces a topos T(A) in which the amalgamation of all of its commutative subalgebras comprises a single commutative C*-algebra. According to the constructive Gelfand duality theorem of Banaschewski and Mulvey, the latter has an internal spectrum S(A) in T(A), which in our approach plays the role of a quantum phase space of the system. Thus we associate a locale (which is the topos-theoretical notion of a space and which intrinsically carries the intuitionistic logical structure of a Heyting algebra) to a C*-algebra (which is the noncommutative notion of a space). In this setting, states on A become probability measures (more precisely, valuations) on S(A), and self-adjoint elements of A define continuous functions (more precisely, locale maps) from S(A) to Scott's interval domain. Noting that open subsets of S(A) correspond to propositions about the system, the pairing map that assigns a (generalized) truth value to a state and a proposition assumes an extremely simple categorical form. Formulated in this way, the quantum theory defined by A is essentially turned into a classical theory, internal to the topos T(A).

Non-Gaussianity test for discriminating gravitational wave backgrounds around 0.1-1Hz

description: We propose a non-Gaussianity test for gravitational wave backgrounds by combining data streams of multiple detectors. This simple method allows us to check whether a detected background is "smooth" enough to be consistent with an inflation-type background, or is contaminated by individually undetectable weak burst signals. The proposed test would be quite useful for the Big Bang Observer or DECIGO whose primary target is a background from inflation at 0.1-1Hz where gravitational wave bursts from supernovae of population III stars might become a troublesome foreground.

Dialektyka paradygmatu głębi i powierzchowności – potrzeba głębszych relacji i pogłębionej edukacji – w perspektywie personalizmu uniwersalistycznego

description: Człowiek jako istota myśląca, duchowa zawsze pragnie czegoś więcej, głębiej, wyżej. Dzięki temu poznawał świat, tworzył wynalazki, rozwijał siebie w wymiarze indywidualnym, społecznym i kulturowym. Równocześnie jakieś potężne przyspieszenie, będące naturalną konsekwencją tejże wynalazczości spowodowało, że coraz częściej to „głębiej” przeradzało się w jakieś dziwne „płycej”. Wiele osób bije na alarm, że powierzchowność myślenia, relacji i ostatecznie życia degraduje człowieka jako człowieka, jako osobę, jako kogoś poszukującego sensu i głębi życia (V. Frankl). Dlatego wyczuwa się coraz powszechniejszą potrzebę wzmacniania i pogłębiania realnych relacji interpersonalnych i zarazem edukacji, która będzie człowiekowi pomagać bardziej być, a nie tylko mieć. Personalizm uniwersalistyczny, gdzie szczególnie mocno promuje się człowieka jako osobę, kogoś wyjątkowego i zarazem wspólnotę osób, może być wielkim kołem ratunkowym dla zagrożonego człowieczeństwa, aby człowiek – osoba odzyskiwał swoją głębię i blask.

description: We have observed the central region of the IR-dark cloud filament associated with IRAS 18507+0121 at millimeter wavelengths in CO(1-0), 13CO(1-0), and C18O(1-0) line emission and with the Spitzer Space Telescope at mid-IR wavelengths. Five massive outflows from two cloud cores were discovered. Three outflows are centered on or near an Ultracompact HII region (G34.4+0.23) while the remaining two outflows originate from the millimeter core G34.4+0.23 MM. Modeling of the SEDs of the mid-IR sources identified 31 young stellar objects in the filament with a combined stellar mass of ~127 +/- 27 Msun. An additional 22 sources were identified as probable cluster members based on the presence of strong 24 micron emission. The total star formation efficiency in the G34.4 cloud filament is estimated to be ~7% while the massive and intermediate mass star formation efficiency in the entire cloud filament is estimated to be roughly 2%. A comparison of the gravitational binding energy with the outflow kinetic energy suggests that the compact core containing G34.4+0.23 MM is being destroyed by its molecular outflows whereas the outflows associated with more massive core surrounding the G34.4 UC HII region are not likely to totally disrupt the cloud. Additionally, a qualitative evaluation of the region appears to suggest that stars in this region may have formed in two stages: first lower mass stars formed and then, a few Myrs later, the more massive stars began to form.

Interplay between Bonding and Magnetism in the Adsorption of NO on Rh Clusters

description: We have studied the adsorption of NO on small Rh clusters, containing one to five atoms, using density functional theory in both spin-polarized and non-spin-polarized forms. We find that NO bonds more strongly to Rh clusters than it does to Rh(100) or Rh(111); however, it also quenches the magnetism of the clusters. This (local) effect results in reducing the magnitude of the adsorption energy, and also washes out the clear size-dependent trend observed in the non-magnetic case. Our results illustrate the competition present between the tendencies to bond and to magnetize, in small clusters.

Theory of Thermal Conductivity on Excitonic Insulator

description: We study the thermal conductivity in the excitonic insulator using a simple quasi one-dimensional two-band model consisting of electron and hole bands with the Coulomb interactions between these bands. Based on the linear response theory within a mean-field scheme, we develop a method to identify the contributions to thermal conductivity driven by excitonic insulator. It is found that there is an additional heat current operator owing to the excitonic phase transition, and that it gives contributions to thermal conductivity which are not expressed in the form of Sommerfeld-Bethe relations written in the form of an imaginary-time derivative of the electric current operator. Finally, we discuss the relationship between the newly-found additional contribution and the heat current carried by excitons.

Normalized least-squares estimation in time-varying ARCH models

description: We investigate the time-varying ARCH (tvARCH) process. It is shown that it can be used to describe the slow decay of the sample autocorrelations of the squared returns often observed in financial time series, which warrants the further study of parameter estimation methods for the model. Since the parameters are changing over time, a successful estimator needs to perform well for small samples. We propose a kernel normalized-least-squares (kernel-NLS) estimator which has a closed form, and thus outperforms the previously proposed kernel quasi-maximum likelihood (kernel-QML) estimator for small samples. The kernel-NLS estimator is simple, works under mild moment assumptions and avoids some of the parameter space restrictions imposed by the kernel-QML estimator. Theoretical evidence shows that the kernel-NLS estimator has the same rate of convergence as the kernel-QML estimator. Due to the kernel-NLS estimator's ease of computation, computationally intensive procedures can be used. A prediction-based cross-validation method is proposed for selecting the bandwidth of the kernel-NLS estimator. Also, we use a residual-based bootstrap scheme to bootstrap the tvARCH process. The bootstrap sample is used to obtain pointwise confidence intervals for the kernel-NLS estimator. It is shown that distributions of the estimator using the bootstrap and the ``true'' tvARCH estimator asymptotically coincide. We illustrate our estimation method on a variety of currency exchange and stock index data for which we obtain both good fits to the data and accurate forecasts.

The role of model bias for prediction skill and methods to constrain it
Creators: name: Counillon Francois
Publisher: name: Zenodo
Year: 2019

description: The very large bias in earth system model will not dramatically change as resolution is increasing or more physical process are included. These biases are the biggest challenge of climate prediction as data assimilation methods are assuming (wrongly) them to be unbiased. Furthermore, these models have too many parameters to be tuned and data are lacking for parameter estimation, with even the most advanced scheme only achieving moderate success. A different approach is to generate a new model (a supermodel) that is based on an ensemble of imperfect models. In super-modelling, the imperfect models are first connected in run time, so that they synchronize, using a set of coefficients or weights that controls their attractor strength. Second, it is possible to estimate the weight so that the supermodel match best key observations (e.g. bias, rmse, kurtosis, …). The optimal weights are then fixed. The new supermodel can be used for climate prediction meaning that it can assimilate data and provide a forecast as before but it will have reduced bias and improved agreement with observations.

There are different ways to achieve synchronisation: directly combining the tendencies of the different models or by nudging their states; by using every permutation of inter-model attractions or by attracting each to a weighted mean. The simplest scheme is the centralised scheme, where the mean state of each individual model is attracted to the weighted mean of the imperfect models. We first show that the approach can be successful with Lorentz 63 and we present then the result from a first super earth system model that connects three state-of-the-art earth system models. Because the models have different native coordinates and resolutions, we use data assimilation (the ensemble optimal interpolation) to propagate the information of the weighted mean to each individual model and its respective grid. We show that in most locations the system can achieve synchronisation and despite using equal weights as a first test, we are able to reduce the bias in the imperfect models.
