description: We generalize the $N_F=2$ Schwinger model on the lattice by adding a charged scalar field. In this so-called $χUϕ_2$ model the scalar field shields the fermion charge, and a neutral fermion, acquiring mass dynamically, is present in the spectrum. We study numerically the mass of this fermion at various large fixed values of the gauge coupling by varying the effective four-fermion coupling, and find an indication that its scaling behavior is the same as that of the fermion mass in the chiral Gross-Neveu model. This suggests that the $χUϕ_2$ model is in the same universality class as the Gross-Neveu model, and thus renormalizable and asymptotic free at arbitrary strong gauge coupling.

description: Morphological variation is the outward manifestation of development and provides fodder for adaptive evolution. Because of this contingency, evolution is often thought to be biased by developmental processes and functional interactions among structures, which are statistically detectable through forms of covariance among traits. This can take the form of substructures of integrated traits, termed modules, which together comprise patterns of variational modularity. While modularity is essential to an understanding of evolutionary potential, biologists currently have little understanding of its genetic basis and its temporal dynamics over generations. To address these open questions, we compared patterns of craniofacial modularity among laboratory strains, defined mutant lines and a wild population of zebrafish (Danio rerio). Our findings suggest that relatively simple genetic changes can have profound effects on covariance, without greatly affecting craniofacial shape. Moreover, we show that instead of completely deconstructing the covariance structure among sets of traits, mutations cause shifts among seemingly latent patterns of modularity suggesting that the skull may be predisposed towards a limited number of phenotypes. This new insight may serve to greatly increase the evolvability of a population by providing a range of ‘preset’ patterns of modularity that can appear readily and allow for rapid evolution.

description: Coffee table books are filled with them: the clichés of Havana as "frozen in time", scented with "nostalgia for a bygone era". At first sight, the city's unique combination of urban design and architectural styles suggest a tension between the island's various historical and political periods. At second glance, the tension lessens into what is a mostly complimentary relationship between patterns, designs, and vision. That is, a city made rich by its combination of continuous innovation and historic preservation. The result is an avant-garde, mostly European (compact, pedestrian, grid-based), urban planning agenda with many assets and challenges to its name. This photo essay aims to: examine how Havana’s colonial history created the city’s basic modern grid street pattern, compact block structure; identify what elements make Havana's urban character different from that of other major Latin American cities; observe current projects as outlined by the New Master Plan; and, finally identify challenges ahead. By covering these points, the essay sets out to challenge the “frozen in time” perception of Havana by replacing it with one of a unique and historically rich city on the brink of major changes.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: One-dimensional spinless Bose and Fermi gases with contact interactions have the close interrelation via Girardeau's Bose-Fermi mapping, leading to the correspondences in their energy spectra and thermodynamics. However, correlation functions are in general not identical between these systems. We derive in both systems the exact universal relations for correlation functions, which hold for any energy eigenstate and any statistical ensemble of the eigenstates with or without a trapping potential. These relations include the large-momentum behaviors of static structure factors and of momentum distributions as well as energy relations, which connect the sums of kinetic and interaction energies to the momentum distributions. The relations involve two- and three-body contacts, which are the integrals of local pair and triad correlations, respectively. We clarify how the relations for bosons and fermions differ and are connected with each other. In particular, we find that the three-body contact makes no contribution to the bosonic energy relation, but it plays a crucial role in the fermionic one. In addition, we compute the exact momentum distribution for any number of fermions in the unitary limit.

description: We classify finitely generated, residually finite automorphism-induced HNN-extensions in terms of the residual separability of a single associated subgroup. This classification provides a method to construct automorphism-induced HNN-extensions which are not residually finite. We prove that this method can never yield a "new" counter-example to Gromov's conjecture on the residual finiteness of hyperbolic groups.

description: The aim of this review is to summarize the current state ofknowledge on process research regarding common factorsin psychotherapy of obsessive-compulsive disorders (OCD).A systematic literature search of medical and psychologicalpublications since 2000 was conducted. Only 8 publicationsfulfilled our inclusion criteria: being a psychotherapy study,investigating potential mediators of change, and respectingthe time line issue. Most of them focused on potential cognitive factors. The change of dysfunctional obsessive beliefs, particularly perfectionism and certainty beliefs, seemsto be important for a successful reduction of OCD symptoms.Patient adherence also seems to play a certain role asa mediator. Concerning the effect of depression, the analysisleaves us with inconsistent results regarding the directionand extent of the found effect. Exploring ‘complexity’as a potential change factor of the therapy process, 1 studyfound the steepest change gradient before an interventionwith exposure-reaction management took place. Case formulation and avoidance did not turn out to be mediators of change. Overall, the limited number of available studies,their focus on different constructs, and their often contradictory results show the need for meaningful, longitudinal research in the field of OCD.

description: We study $M$-alternating Hamilton paths and $M$-alternating Hamilton cycles in a simple connected graph $G$ on $ν$ vertices with a perfect matching $M$. Let $G$ be a bipartite graph, we prove that if for any two vertices $x$ and $y$ in different parts of $G$, $d(x)+d(y)\geq ν/2+2$, then $G$ has an $M$-alternating Hamilton cycle. For general graphs, a condition for the existence of an $M$-alternating Hamilton path starting and ending with edges in $M$ is put forward. Then we prove that if $κ(G)\geqν/2$, where $κ(G)$ denotes the connectivity of $G$, then $G$ has an $M$-alternating Hamilton cycle or belongs to one class of exceptional graphs. Lou and Yu \cite{LY} have proved that every $k$-extendable graph $H$ with $k\geqν/4$ is bipartite or satisfies $κ(H)\geq 2k$. Combining this result with those we obtain we prove the existence of $M$-alternating Hamilton cycles in $H$.

description: We report the discovery of an X-ray transient, observed in outburst with XMM-Newton on March 20, 2003, and with position 18h12m27.8s, -18 12 34 (J2000, approximate positional error 2"). No known source is present at this position and the source was not detected during published ROSAT or ASCA observations of that region. However, the source may be associated with 1H1812-182 detected by HEAO 1, although the error bars on the HEAO 1 position are very large and the two sources could also be unrelated. Therefore, we name the source XMMU J181227.8-181234. Initially, the source was not detected using the All-Sky Monitor (ASM) on-board the Rossi X-ray Timing Explorer, however, reprocessing of the ASM data shows that the source was in fact detected and it was active for about 50 days. The X-ray spectrum of this transient is fitted equally well by an absorbed power-law (with a spectral index of 2.5) or multi-colour disk blackbody model (with kT ~ 2 keV), where we find that the source is highly absorbed. We detect an unabsorbed 0.5-10 keV flux in the range (2-5)E-9 ergs cm^{-2} s^{-1}, which at a distance of 8 kpc corresponds to a 0.5-10 keV luminosity of (1-4)E37 ergs s^{-1}. No pulsations were detected by timing analysis. A colour-colour diagram from ASM data of different accreting objects suggests that the transient is a high-mass X-ray binary, as is also suggested by the high absorption compared to the average interstellar value in the direction of the source. However, the power-law spectral index is far more typical of a low-mass X-ray binary. Thus, we are unable to conclusively identify the nature of the transient. We also report on three sources first detected by the ASCA Galactic Plane Survey that are close to this transient.

description: We calculate the electromagnetic fields generated in small systems by using a multiphase transport (AMPT) model. Compared to $A+A$ collisions, we find that the absolute electric and magnetic fields are not small in $p$+Au and $d$+Au collisions at energies available at the BNL Relativistic Heavy Ion Collider and in $p$+Pb collisions at energies available at the CERN Large Hadron Collider. We study the centrality dependencies and the spatial distributions of electromagnetic fields. We further investigate the azimuthal fluctuations of the magnetic field and its correlation with the fluctuating geometry using event-by-event simulations. We find that the azimuthal correlation $\left\langle \cos2(Ψ_B - Ψ_{2}) \right\rangle$ between the magnetic field direction and the second harmonic participant plane is almost zero in small systems with high multiplicities, but not in those with low multiplicities. This indicates that the charge azimuthal correlation, $\left\langle \cos(ϕ_α+ϕ_β - 2Ψ_{RP}) \right\rangle$, is not a valid probe to study the chiral magnetic effect (CME) in small systems with high multiplicities. However, we suggest searching for possible CME effects in small systems with low multiplicities.

description: We analyze the chiral Schwinger model on an infinite lattice using the continuum definition of the fermion determinant and a linear interpolation of the lattice gauge fields. For non-compact and Wilson formulation of the gauge field action it is proven that the effective lattice model is Osterwalder-Schrader positive, which is a sufficient condition for the reconstruction of a physical Hilbert space from the model defined on a Euclidean lattice. For the non-compact model we furthermore establish the existence of critical points where the corresponding continuum theory can be reconstructed. We show that the continuum limit for the two-point functions of field strength and chiral densities can be controlled analytically. The article ends with some remarks on fermionic observables.

description: We give a derivation for the indirect interaction between two magnetic dipoles induced by the quantized electromagnetic field. It turns out that the interaction between permanent dipoles directly returns to the classical form; the interaction between transition dipoles does not directly return to the classical result, yet returns in the short-distance limit. In a finite volume, the field modes are highly discrete, and both the permanent and transition dipole-dipole interactions are changed. For transition dipoles, the changing mechanism is similar with the Purcell effect, since only a few number of nearly resonant modes take effect in the interaction mediation; for permanent dipoles, the correction comes from the boundary effect: if the dipoles are placed close to the boundary, the influence is strong, otherwise, their interaction does not change too much from the free space case.

Identification of new long-lived particle states using deep neural networks
Creators: name: Komm, Matthias
Publisher: name: Zenodo
Year: 2019

description: We present preliminary studies of a deep neural network (DNN) "tagger" that is trained to identify the presence of displaced jets arising from the decays of new long-lived particle (LLP) states in data recorded by the CMS detector at the CERN LHC. Particle-level candidates, as well as secondary vertex information, are refined through the use of convolutional neural networks (CNNs) before being combined with high-level engineered variables via a dense neural network. The LLP lifetime is a parameter of the neural network model, which allows for hypothesis testing over several orders of magnitude in lifetime, from ctau = 1 um to 10 m. The network training is performed by streaming ROOT trees containing O(100M) jets directly into the TensorFlow queue and threading system. This custom workflow allows a flexible selection of input features and the asynchronous preprocessing of data, such as the resampling and shuffling of batches on the CPU, in parallel to training on the GPU. Domain adaptation is performed with CMS control region data to ensure that MC simulation can be used to accurately model candidate signal events in data. The technical implementation, architecture, workflows, and potential applications are described. We will demonstrate the tagger performance as evaluated with both MC simulation and control region data. Preliminary studies also demonstrate the potential for a universal, model-independent performance for a broad range of signal model hypotheses, such as long-lived resonances.

description: The von Neumann entropy density of a block of n spins is proved to be non-zero for large n in the non-equilibrium steady state of the XY chain constructed by coupling a finite cutout of the chain to the two infinite parts to its left and right which act as thermal reservoirs at different temperatures. Moreover, the non-equilibrium density is shown to be strictly greater than the density in thermal equilibrium.
A Hamilton-Jacobi theory for implicit differential systems

description: In this paper, we propose a geometric Hamilton-Jacobi theory for systems of implicit differential equations. In particular, we are interested in implicit Hamiltonian systems, described in terms of Lagrangian submanifolds of $TT^*Q$ generated by Morse families. The implicit character implies the nonexistence of a Hamiltonian function describing the dynamics. This fact is here amended by a generating family of Morse functions which plays the role of a Hamiltonian. A Hamilton--Jacobi equation is obtained with the aid of this generating family of functions. To conclude, we apply our results to singular Lagrangians by employing the construction of special symplectic structures.

The unitarity requirement on spinning particles, known as Higuchi bound, plays a crucial role for the size of the observable signal.

description: Increasing technology uptake in the nonprofit sector will allow nonprofit organizations and social workers to provide more effective services through improved work processes. The following paper will discuss how these processes (service delivery, fundraising, and outreach) are carried out in the nonprofit sector given the current technology landscape in nonprofits. I will provide background information about innovations such as cloud computing systems, social media, and mobile technologies that should be incorporated into the nonprofit sector in order to improve the quality of services and work processes. An overview of the barriers that nonprofits face, such as lack of knowledge, lack of resources, and demands by funders, will explain the challenges accompanying increased technology uptake. The final section provides a method to overcome obstacles, allowing the optimal integration of technology into the nonprofit sector.

description: We study a fermionic dark matter model in which the interaction of the dark and visible sectors is mediated by Higgs portal type couplings. Specifically, we consider the mixing of a dark sector scalar with the scalars of a Two Higgs Doublet Model extension of the Standard Model. Given that scalar exchange will result in a spin-independent dark matter-nucleon scattering cross section, such a model is potentially subject to stringent direct detection constraints. Moreover, the addition of new charged scalars introduce non-trivial flavour constraints. Nonetheless, this model allows more freedom than a standard Higgs portal scenario involving a single Higgs doublet, and much of the interesting parameter space is not well approximated by a Simplified Model with a single scalar mediator. We perform a detailed parameter scan to determine the mass and coupling parameters which satisfy direct detection, flavour, precision electroweak, stability, and perturbativity constraints, while still producing the correct relic density through thermal freezeout.

description: Santiago de Compostela has been a pilgrimage site for centuries. It was founded due to the discovery of the tomb of St. James (Santiago), whose remains are said to lie inside the city’s famous cathedral. Compostela is, nonetheless, a modest city of around 100,000 inhabitants, with a small but consolidated historic centre, and is the cultural and political centre of Galicia. It is the capital of the autonomic community of northwest Spain.
With the objective of projecting Galicia as a centre of culture and knowledge on the world stage, the Xunta de Galicia (Council of Galicia) approved the construction of a monumental building complex over the top of Monte Gaiás, a hill that dominates Santiago and its surrounding topography. Construction began in 2001, supervised by architect Peter Eisenman, and the structure is still incomplete. The project has provoked a great deal of controversy, transcending all sectors of Gallegan and Spanish society. It has become an enormous expenditure for a Gallegan economy that is still one of the most traditional and modest in Spain. The controversy is especially sensitive given that Spain is already enduring a profound economic crisis. Critics say the project lacks clear purpose, without a sense of mission for the uses of the new buildings. This is especially so when contrasted to the historic centre of the city, a complete success in terms of public space habitability and economic solvency (due to tourism). One can only ask: Why, in front of such an exemplary model of small-scale, high-impact development, promoting long-term, ‘small-dose’ growth, is a complex built that opposes all the values of the community and city it represents? Haven’t the Gallegans learnt from their millenary past and their strong cultural heritage? It is becoming more evident, with time, that the City of Culture (Ciudad de la Cultura), the new development, is an example of what should not be done in the fields of urban and social development, at least in the context into which it has been inserted.
The Beauty Ideal: The Effects Of European Standards Of Beauty On Black Women
Creators: Bryant, Susan L.
Publisher: name: Columbia University
Year: 2013
Subjects: Social service

description: Black women are particularly vulnerable to the effects of European standards of beauty, because these standards emphasize skin colors and hair types that exclude many black women, especially those of darker skin. Using a social work lens, this article explores the black woman ’s internalization of European beauty standards through family, peers, the media, and society, and the related outcomes of this internalization on self-perception, academic achievement, sexual behavior, employment, marital status, and mental health. A review of the research indicates that European standards of beauty can have damaging effects on the life trajectories of black women, especially those with dark skin, primarily in the form of internalized self-hatred. Suggestions are made for social work practitioners to address the effects of these internalized European beauty standards among black women through programming and clinical practice.

description: It is well established that different factors affect milk composition in cows and that milk composition, in turn, affect both technological and nutritional qualities. In this respect the comprehension of the metabolic variability of milk composition in relation to the lactation time as well as to the genetic background may be of paramount importance for the agri-food industries. In the present study we investigated the variations of the metabolic profiles during lactation in milks obtained from Friesian and autochthonous races from Northern Italy by 1H NMR metabolomics. Furthermore, the external factors influencing the milk composition were minimized: the cows were breeded in the same farm, were fed with the same diet and were paired for the lactation interval and lactation stage. Our results showed a difference in milk composition between races and in relation to late lactation. The PLS-DA analysis permitted to distinguish the Friesian and autochthonous cow milks at the investigated different lactation times. Interestingly, the metabolites significantly involved into the discrimination between races appeared to be also technological property parameters, highlighting the importance of maintaining the biodiversity of cow breeds. Therefore, NMR-based metabolomics of milk could represent an informative tool to identify metabolites involved in milk quality both from a nutritional and industrial perspective.

description: In a previous publication, we have presented a model for the photoproduction of $\mathrm{J/}ψ$ vector mesons off protons, where the proton structure in the impact-parameter plane is described by an energy-dependent hot-spot profile. Here we extend this model to study the photonuclear production of $\mathrm{J/}ψ$ vector mesons in coherent and incoherent interactions of heavy nuclei. We study two methods to extend the model to the nuclear case: using the standard Glauber-Gribov formalism and using geometric scaling to obtain the nuclear saturation scale. We find that the incoherent cross section changes sizably with the inclusion of subnucleonic hot spots, and that this change is energy dependent. We propose to search for this behavior by measuring the ratio of the incoherent to coherent cross section at different energies. We compare the results of our model to results from RHIC and from the Run 1 at the LHC finding a satisfactory agreement. We also present predictions for the LHC at the new energies reached in Run 2. The predictions include $\mathrm{J/}ψ$ production in ultra-peripheral collisions, as well as the recently observed photonuclear production in peripheral collisions.

description: The use of IPv6 on the general internet continues to grow. Several Broadband/Mobile-phone companies, such as T-Mobile in the USA and BT/EE in the UK, now use IPv6-only networking with connectivity to the IPv4 legacy world enabled by the use of NAT64/DNS64/464XLAT. Large companies, such as Facebook, use IPv6-only networking within their internal networks, there being good management and performance reasons for this. The transition of WLCG central and storage services to dual-stack IPv4/IPv6 is progressing well, thus enabling the use of IPv6-only CPU resources as agreed by the WLCG Management Board and presented by us at earlier CHEP conferences. During the last year, the HEPiX IPv6 working group has not only been chasing and supporting the transition to dual-stack services, but has also been encouraging network monitoring providers to allow for filtering of plots by the IP protocol used. We have investigated and fixed the reasons for the use of IPv4 between two dual-stack endpoints when IPv6 should be preferred. We present this work and the tests that have been made of IPv6-only CPU showing the successful use of IPv6 protocols in accessing WLCG services. The dual-stack deployment does however result in a networking environment which is much more complex than when using just IPv6. Some services, e.g. the EOS storage system at CERN, are using IPv6-only for internal communication, where possible. The group is investigating the removal of the IPv4 protocol in more places. We will present the areas where this could be useful and possible and suggest a timetable for being able to turn off IPv4 in this way.
The Public And The Profession’s Perception Of Social Work
Creators: Olin, Jeffrey

Year: 2013
Subjects: Social service

description: The social work profession has long been concerned about its mission and perception. The two interests go hand in hand, because to have an effect on how we as social workers are viewed, we must be self-aware about who we are and what we do. This paper will address how social work periodically reflects upon and re-assesses its purpose because of internal considerations, such as the profession ’s ethics, and external forces, including the job market and public perception. Some of the research conducted over the years into public perception of social work  as well as that of our clients  will be presented and compared. In addition, I review how the media have portrayed the field, and how we as professionals have marketed ourselves. Finally, some suggestions will be offered, which can be applied at various levels, including direct practice, program development and evaluation, administration, and branding of the profession as a whole.
Suicide And Soul Wound: Stress, Coping, And Culture In The American Indian And Alaska Native Youth Context

description: Suicide, the second leading cause of death for American Indian and Alaska Native (AI) youth ages 15 to 24, raises a critical issue for social work research and practice. This paper argues that AI youth suicide is a contemporary manifestation of “soul wound” and expands the definition of soul wound to include present stressors and coping mechanisms for youth that are characterized by a legacy of colonization and cultural oppression. While AI youth come from diverse communities, this paper will demonstrate the importance of examining youth suicide as part of the overall AI experience in the United States. Using an indigenist stress process model framework, it will subsequently examine four forms of stressors informed by the marginalization of the AI population: psychological strains of historical trauma, environmental stressors, quotidian stressors arising from socio-economic factors, and adversity from personal and relational role conflicts. AI youth mediate these stressors through coping mechanisms around social support and collective mastery. This paper will conclude with a call to develop an anti-oppressive, culturally relevant social work practice that supports meaningful identity development and collective efficacy.

description: In this paper we are concerned with the existence of invariant tori in nearly integrable Hamiltonian systems \begin{equation*} H=h(y)+f(x,y,t), \end{equation*} where $y\in D\subseteq\mathbb{R}^n$ with $D$ being a closed bounded domain, $x\in \mathbb{T}^n$, $f(x,y,t)$ is a real analytic almost periodic function in $t$ with the frequency ${ω}=(\cdots,{ω}_λ,\cdots)_{λ\in \mathbb{Z}}\in \mathbb{R}^{\mathbb{Z}}$. As an application, we will prove the existence of almost periodic solutions and the boundedness of all solutions for the second order differential equations with superquadratic potentials depending almost periodically on time.

The Intersection of Corporate Social Responsibility and the Non-Profit Industrial Complex Exploitative Child Labor in Côte d'Ivoire's Chocolate Industry

description: This article examines the role of the chocolate industry in the exploitation of children on cocoa farms in Côte d'Ivoire. Under the guise of corporate social responsibility (CSR), the chocolate industry has used its power in the United States to shape policy and program-level initiatives to address the worst forms of child labor, while protecting its business interests and disregarding poverty as the root cause of the problem. The non-profit industrial complex (NPIC) limits the ability of international non-governmental organizations (INGOs) to effectively implement programs that address poverty. The increasing CSR funding to INGOs prevents them from holding the chocolate industry accountable. Further, this article discusses the unique contribution of the social work profession in creating the social and structural change required to mitigate the negative consequences of the relationship between CSR and the NPIC.
Intimate Partner Violence: Restorative Justice and Trauma-informed Care

description: The social work profession is positioned to play a critical role in redefining services for responsible parties in intimate partner violence. The traditional approaches to intimate partner violence services, which focus on confrontational rehabilitation rather than therapy, are due to undergo a shift. Models of trauma-informed care and restorative justice are promising alternatives for responsible parties and harmed parties alike. By building on the transformative work advocates have already done around intimate partner violence for harmed parties and focusing on the inclusion of the diverse identities of those we serve, we can begin to form a nuanced response to a nuanced social issue. From trauma-informed care, we can learn to make space for the personal trauma histories of survivors as well as those who have harmed them. From restorative justice, we can learn about techniques that have helped bring a sense of justice and healing to individuals, families, and communities affected by intimate partner violence, including those who have perpetrated that violence.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We study ghost-free multimetric theories for $(N+1)$ tensor fields with a coupling to matter and maximal global symmetry group $S_N\times(Z_2)^N$. Their mass spectra contain a massless mode, the graviton, and $N$ massive spin-2 modes. One of the massive modes is distinct by being the heaviest, the remaining $(N-1)$ massive modes are simply identical copies of each other. All relevant physics can therefore be understood from the case $N=2$. Focussing on this case, we compute the full perturbative action up to cubic order and derive several features that hold to all orders in perturbation theory. The lighter massive mode does not couple to matter and neither of the massive modes decay into massless gravitons. We propose the lighter massive particle as a candidate for dark matter and investigate its phenomenology in the parameter region where the matter coupling is dominated by the massless graviton. The relic density of massive spin-2 can originate from a freeze-in mechanism or from gravitational particle production, giving rise to two different dark matter scenarios. The allowed parameter regions are very different from those in scenarios with only one massive spin-2 field and more accessible to experiments.

description: We propose a machine-learning method for evaluating the potential barrier governing atomic transport based on the preferential selection of dominant points for the atomic transport. The proposed method generates numerous random samples of the entire potential energy surface (PES) from a probabilistic Gaussian process model of the PES, which enables defining the likelihood of the dominant points. The robustness and efficiency of the method are demonstrated on a dozen model cases for proton diffusion in oxides, in comparison with a conventional nudge elastic band method.
