description: In the setting of high-dimensional linear models with Gaussian noise, we investigate the possibility of confidence statements connected to model selection. Although there exist numerous procedures for adaptive point estimation, the construction of adaptive confidence regions is severely limited (cf. Li, 1989). The present paper sheds new light on this gap. We develop exact and adaptive confidence sets for the best approximating model in terms of risk. Our construction is based on a multiscale procedure and a particular coupling argument. Utilizing exponential inequalities for noncentral $chi^2$--distributions, we show that the risk and quadratic loss of all models within our confidence region are uniformly bounded by the minimal risk times a factor close to one.

description: We consider an integrable model describing an Anderson-like impurity coupled to an open $t$--$J$ chain. Both the hybridization (i.e. its coupling to bulk chain) and the local spectrum can be controlled without breaking the integrability of the model. As the hybridization is varied, holon and spinon bound states appear in the many body ground state. Based on the exact solution we study the state of the impurity and its contribution to thermodynamic quantities as a function of an applied magnetic field. Kondo behaviour in the magnetic response of the impurity can be observed provided that its parameters have been adjusted properly to the energy scales of the holon and spinon excitations of the one-dimensional bulk.

description: The decoupling of the eta meson from the nucleon, as recently deduced from analyzing \bar p p collisions and eta photoproduction off the proton at threshold, is shown to provide an argument against the octet Goldstone boson nature of the eta meson. This argument concerns the structure of the strong isoscalar axial vector current. A vanishing eta-N coupling means a vanishing contribution of the eta-pole term to the hypercharge nucleon axial vector current. Therefore, no partial conservation of the latter can be achieved. This new situation invalidates the octet Goldberger--Treiman relation for the eta-N coupling constant that is indicative of the octet Goldstone boson nature of the eta meson. In such a case there is no longer a compelling reason for the standard belief that the eta meson should be coupled to the hadronic vacuum through the hypercharge axial vector current. Rather, it will be coupled to it as any ordinary neutral pseudoscalar meson via the neutral axial vector current of the electroweak theory. As a result of the suggested universal structure of the weak and strong neutral axial vector currents the eta meson satisfies the strange analog of the Goldberger-Treiman relation so that it acquires features of a strange Goldstone boson. Hence the eta-NN vertex constant appears proportional to $Δs$, the fraction of nucleon spin carried by the strange quark sea, thus explaining its suppression naturally.

description: This paper describes an interdisciplinary project: the design and fabrication of temporary HVAC diffusers for the University of Louisiana Lafayette School of Architecture and Design to decrease and distribute air supply across the studio environment. To begin the design process, we charged the students to record data measuring the air velocity around the existing diffusers using an anemometer, creating a grid of yarn to located points in space. In addition to collecting the numerical data, the student observed the movement of the lengths of yarn in response to the airflow. Once the students could visualize the movement of the air, they hypothesized on how best to control the air. Several designs provided variations on ductwork typology, featuring perforations or shaping flanges to distribute the air. By contrast, three designs employed rudders or fins and waterfall-like shelf structures to create spouts, conceiving of the air as a fluid. With a task to spread and slow the air, these solutions were destined to be most successful. The project acts as a case study on data collection, research, and design for environmental factors. Students learned how to frame a research question, follow an organized practice of data collection and analysis, relate that data to industry-established standards, hypothesize about solutions through prototyping, test those solutions through digital analysis, and then verify hypotheses through empirical collection of data once their design was installed. This methodology allowed students to relate benchmarks established by ASHRAE’s standards for comfort to the qualitative experience of their own design. Additionally, this project serves as an example of cross-disciplinary research, and provides a model for college initiated grant development, specifically tailored to STEM.

description: In this work we study in a general view slow rotating planets as Venus or Titan which present superrotating winds in their atmospheres. We are interested in understanding what mechanisms are candidates to be sources of net angular momentum to generate this kind of dynamics. In particular, in the case of Venus, in its atmosphere around an altitude of 100 Km relative to the surface, there exists winds that perform a full rotation around the planet in four terrestrial days, whereas the venusian day is equivalent to 243 terrestrial ones. This phenomenon called superrotation is known since many decades. However, its origin and behaviour is not completely understood. In this article we analise and ponderate the importance of different effects to generate this dynamics.
Weak gravity conjecture in the asymptotical dS and AdS background

description: The cosmological observations provide a strong evidence that there is a positive cosmological constant in our universe and thus the spacetime is asymptotical de Sitter space. The conjecture of gravity as the weakest force in the asymptotical dS space leads to a lower bound on the U(1) gauge coupling $g$, or equivalently, the positive cosmological constant gets an upper bound $ρ_V \leq g^2 M_p^4$ in order that the U(1) gauge theory can survive in four dimensions. This result has a simple explanation in string theory, i.e. the string scale $\sqrt{α'}$ should not be greater than the size of the cosmic horizon. Our proposal in string theory can be generalized to U(N) gauge theory and gives a guideline to the microscopic explanation of the de Sitter entropy. The similar results are also obtained in the asymptotical anti-de Sitter space.

description: We show how to define a dynamical topological invariant for general one-dimensional topological systems after a quantum quench. Focusing on two-band topological insulators, we demonstrate that the reduced momentum-time manifold can be viewed as a series of submanifold $S^2$, and thus we are able to define a dynamical topological invariant on each of the sphere. We also unveil the intrinsic relation between the dynamical topological invariant and the difference of topological invariant of the initial and final static Hamiltonian. By considering some concrete examples, we illustrate the calculation of the dynamical topological invariant and its geometrical meaning explicitly.

description: In this paper, we explore how the contextual ambiguity of a search can affect a keyword’s performance. The context of consumer search is often unobserved and the prediction of it can be nontrivial. Consumer search contexts may vary even when consumers are searching for the same keyword. Due to the ambiguity of a keyword, a large portion of the ads displayed may fall outside a particular consumer’s interest, potentially leading to low click-through rates on search engines. In our study, we propose an automatic way of examining keyword contextual ambiguity based on probabilistic topic models from machine learning and computational linguistics. We quantify the effect of contextual ambiguity on keyword click-through performance using a hierarchical Bayesian model that allows for topic-specific effect and nonlinear position effect. We validate our study using a novel dataset from a major search engine that contains information on consumer click activities for 12,790 distinct keywords across multiple product categories from over 4.6 million impressions. We find that consumer click behaviors vary significant across keywords, and keyword category and the contextual ambiguity of the keywords significantly affect such variation. Specifically, higher contextual ambiguity can lead to a higher click-through rate (CTR) on top-positioned ads, but the CTR tends to decay faster with position. Therefore, the overall effect of contextual ambiguity on CTR varies across positions. Our study has the potential to help advertisers design keyword portfolios and bidding strategy by extracting contextual ambiguity and other semantic characteristics of keywords based on large-scale analytics from unstructured data. It can also help search engines improve the quality of displayed ads in response to a consumer search query.

Microscopic analysis of quadrupole collective motion in Cr-Fe nuclei: I. Renormalization of collective states and interacting-boson-model parameters

description: We present a new method by which wavefunctions with simple structure are renormalized so as to contain more complicated structure. This method, called $H^n$-cooling method, is applied to the study of the quadrupole collective motion of $^{56}$Fe, $^{54}$Cr, $^{58}$Fe and $^{56}$Cr. The shell-model wavefunctions of lowest-lying states of these nuclei are well treated by this method. By using the wavefunctions obtained via the $H^n$-cooling method, IBM-2 parameters are derived from a realistic shell-model hamiltonian and transition operators. The Majorana interaction becomes sizably repulsive, primarily as an effect of the renormalization. The bosonic E2 effective-charges are enhanced due to the renormalization, while a quenching occurs in the M1 and M3 parameters for proton bosons. It is shown that the $χ$ parameters take similar values in the hamiltonian and in the E2 operator.

Reduction of the field theory to a point particle framework yields a non-linear harmonic oscillator, which is a special case of similar models studied before in \cite{car}. The connection with noncommutative geometry is also established.

description: Electric generation of spin current via spin Hall effect is of great interest as it allows an efficient manipulation of magnetization in spintronic devices. Theoretically, spin current can be also created by a temperature gradient, which is known as spin Nernst effect. Here, we report spin Nernst effect-induced transverse magnetoresistance in ferromagnet (FM)/non-magnetic heavy metal (HM) bilayers. We observe that the magnitude of transverse magnetoresistance (i.e., planar Nernst signal) in FM/HM bilayers is significantly modified by HM and its thickness. This strong dependence of transverse magnetoresistance on HM evidences the spin Nernst effect in HM; the generation of thermally-induced spin current in HM and its subsequent reflection at the FM/HM interface. Our analysis of transverse magnetoresistance shows that the spin Nernst angles of W and Pt have the opposite sign to their spin Hall angles. Moreover, our estimate implies that the magnitude of the spin Nernst angle would be comparable to that of the spin Hall angle, suggesting an efficient generation of spin current by the spin Nernst effect.

description: Analyses of Impediments to Fair Housing (AIs) are Federally-mandated studies intended to develop an agenda for remedies to structural and operational barriers to fair housing in the U.S. There are few existing evaluations of AI quality, and there is little understanding of how AI results influence fair housing policy. We have developed an evaluation instrument that determines the extent to which AIs meet statutory requirements and use appropriate data and methods. We have applied this instrument to a small national sample of AIs using multiple readers. We find that while there is broad agreement across readers as to whether specific questions are addressed or not, there is considerable variation regarding more detailed measurements of AI quality. Nevertheless, the evaluation instrument appears to provide reliable measures of AI quality across topic areas. This research will enable jurisdictions that perform AIs to develop well-defined quality metrics and to address unique local characteristics.

Non-linearity arises from the electron-lattice interaction and it enables the formation of a variety of stable solitons such as bright solitons, breathers and rogue waves, all of them presenting well defined spin projection onto the molecule axis. A thorough study of the soliton solutions is presented and discussed.

description: Previous research at Carnegie Mellon University introduced a systematic method for public participation in risk ranking. The method has been tested successfully with participants from the United States using school risks and environmental risks. To explore the viability of the method in another cultural setting, it was tested with Chinese participants, because previous research has shown that Americans and Chinese differ substantially along many dimensions of cognition and social organization relevant to decision making. Using 10 environmental hazards based on current environmental regulatory programs in a Chinese city as the risk domain, 5 groups of 8-9 participants ranked the hazards using both holistic and multiattribute approaches. Resulting judgment patterns for the Chinese participants were consistent with those observed in previous studies with Americans, providing additional evidence for the robustness of the method. Risk rankings from the holistic and multiattribute approaches were reasonably consistent, both for individuals and for groups. Explicit and implicit measures indicated that participants were satisfied with the procedures and resulting rankings. Results for Chinese participants were compared with previous results for Americans to look for cultural effects involving risk perception, deference to technical expertise and quantitative analysis, deference to senior group members, adherence to groups’ rankings because of collectivism, and skepticism toward public participation in policy making. Although there were some hints of cultural differences, no cultural effect had a substantial effect on measures of the method’s validity or replicability. Because the Carnegie Mellon method offers a scientifically sound and measured approach to legitimate public involvement, it may be attractive to Chinese leaders as they respond to growing demand for public participation in risk-management policy.

description: The characterization of small samples of cold bosonic atoms in rotating microtraps has recently attracted increasing interest due to the possibility to deal with a few number of particles per site in optical lattices. We analyze the evolution of ground state structures as the rotational frequency $Ω$ increases. Various kinds of ordered structures are observed. For $N<10$ atoms, the standard scenario, valid for large sytems, is absent, and only gradually recovered as $N$ increases. The vortex contribution to the total angular momentum $L$ as a function of $Ω$ ceases to be an increasing function of $Ω$, as observed in experiments of Chevy {\it et al.} (Phys. Rev. Lett. 85, 2223 (2000)). Instead, for small $N$, it exhibits a sequence of peaks showing wide minima at the values of $Ω$, where no vortices appear.

description: We present a new version of our racetrack inflation scenario which, unlike our original proposal, is based on an explicit compactification of type IIB string theory: the Calabi-Yau manifold P^4_[1,1,1,6,9]. The axion-dilaton and all complex structure moduli are stabilized by fluxes. The remaining 2 Kahler moduli are stabilized by a nonperturbative superpotential, which has been explicitly computed. For this model we identify situations for which a linear combination of the axionic parts of the two Kahler moduli acts as an inflaton. As in our previous scenario, inflation begins at a saddle point of the scalar potential and proceeds as an eternal topological inflation. For a certain range of inflationary parameters, we obtain the COBE-normalized spectrum of metric perturbations and an inflationary scale of M = 3 x 10^{14} GeV. We discuss possible changes of parameters of our model and argue that anthropic considerations favor those parameters that lead to a nearly flat spectrum of inflationary perturbations, which in our case is characterized by the spectral index n_s = 0.95.

Although still ongoing, their study has already yielded several lessons worth sharing. The authors consider how making sense of the violence seen on video is no simple task. They conclude that to understand videos of police violence they needed to turn to courts of law rather than directly analysing videos of police violence. In this sense, their research led to an investigation of investigations.

description: We present a spatially-resolved ultraviolet spectrum of a non-radiative shock front in the Cygnus Loop, obtained with the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope (HST). The spectrum covers the wavelength range 1118 - 1716 angstroms, with an effective spectral resolution of ~12 angstroms. The 0.1" spatial resolution of these data provides a huge improvement over earlier ultraviolet spectra, allowing us to study the spatial distribution of high ionization line emission directly behind the shock front. We are able to isolate individual shock features in our spectrum by comparing the STIS spectrum with a WFPC2 H-alpha image of the region. Isolating the brightest shock tangency, we identify lines of NV, CIV, HeII, OV, OIV] and SiIV, and NIV] as well as the hydrogen 2-photon continuum. The NV line peaks about 0.3" behind the CIV and HeII emission and is spatially broader. Also, the observed line ratios of CIV and HeII to NV are higher in our bright shock spectrum than in previous observations of the same filament obtained through much larger apertures, indicating that there must be a more widely distributed component of the NV emission. We calculate shock models and show that the observed separation between the CIV and NV emission zones and observed line intensities constrain the combinations of shock velocity and pre-shock density that are allowed.

Inverted regions induced by geometric constraints on a classical encounter-controlled binary reaction

description: The efficiency of an encounter-controlled two-channel reaction between two independently-mobile reactants on a lattice is characterized by the mean number $\rt$ of steps to reaction. The two reactants are distinguished by their mass with the "light" walker performing a jump to a nearest-neighbor site in each time step, while the "heavy" walker hops only with a probability $p$; we associate $p$ with the "temperature" of the system. Lattices subject to periodic and to confining boundary conditions are considered. For periodic lattices, depending on the initial state, the reaction time either falls off monotonically with $p$ or displays a local minimum with respect to $p$; occurrence of the latter signals a regime where the efficiency of the reaction effectively decreases with increasing temperature. Such behavior disappears if the jump probability of the light walker falls below a characteristic threshold value. In lattices subject to confining boundary conditions, the behavior is more complex. Depending on the initial conditions, the reaction time as a function of $p$ may increase monotonically, decrease monotonically, display a single maximum or even a maximum and minimum. These inverted regions are a consequence of a strictly classical interplay between excluded volume effects implicit in the specification of the two reaction channels, and the system's dimensionality and spatial extent. Our results highlight situations where the description of an encounter-controlled reactive event cannot be described by a single, effective diffusion coefficient. We also distinguish between the inversion region identified here and the Marcus inverted region which arises in electron transfer reactions.

Under trace class perturbation the channel scattering matrices are calculated. Using Feshbach's optical potential it is shown that for a given spectral parameter the channel scattering matrices can be recovered either from a dissipative or from a Lax-Phillips scattering theory.

description: Jackson queuing networks have a lot of practical applications, mainly in services and technologic devices. For the first case, an example are the healthcare networks and, for the second, the computation and telecommunications networks. Evidently the time that a customer - a person, a job, a message … – spends in this kind of systems, its sojourn time[1], is an important measure of its performance, among others. In this work, the practical statistical known results about the sojourn time of a customer, in a Jackson network, distribution are collected and presented. And an emphasis is set on the numerical methods applicable to compute the distribution function and the moments.

Estimation of Monotone Treatment Effects in Network Experiments

description: Randomized experiments on social networks are a trending research topic. Such experiments pose statistical challenges due to the possibility of interference between units. We propose a new method for estimating attributable treatment effects under interference. The method does not require partial interference, but instead uses an identifying assumption that is similar to requiring nonnegative treatment effects. Pre-treatment network observations can be used to customize the test statistic, so as to increase power without making assumptions on the data generating process. The inversion of the test statistic is a combinatorial optimization problem which has a tractable relaxation, yielding conservative estimates of the attributable effect.

Stochastic variational method with noncentral forces

Publisher: name: arXiv
Year: 1996
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: This paper extends the application of the stochastic variational method to noncentral interactions. Several examples are presented for three- and four-nucleon systems with realistic nuclear forces. The correlated Gaussians easily cope with the strong short range repulsion of the potential and the stochastic variational method efficiently selects the most important spin, isospin and orbital angular momentum components of the wave function. The examples confirm the usefulness and accuracy of the method.

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.

Structural properties of linear probabilistic constraints

description: The paper provides a structural analysis of the feasible set defined by linear probabilistic constraints. Emphasis is laid on single (individual) probabilistic constraints. A classical convexity result by Van de Panne/Popp and Kataoka is extended to a broader class of distributions and to more general functions of the decision vector. The range of probability levels for which convexity can be expected is exactly identified. Apart from convexity, also nontriviality and compactness of thefeasible set are precisely characterized at the same time. The relation between feasible sets with negative and nonnegative right-hand side is revealed. Finally, an existence result is formulated for the more difficult case of joint probabilistic constraints.

description: In this article the authors aim to understand the specificity of violence against Black women in Brazilian politics through the analysis of testimonies of Black politicians in different administrative positions and various regions of Brazil. Adopting the “Violence Against Women in Politics” (VAWIP) analytical model developed by Mona Lena Krook, the goal of this approach is to highlight the forms that this violence takes in the Brazilian context when gender and race intersect. In doing so, the article pursues two objectives. First, it offers an overview of violence against Black women in Brazilian politics, demonstrating how this phenomenon manifests itself in the analysis of these cases. Second, it observes how the testimonies of Black women politicians go beyond the analytical model proposed by Mona Lena Krook (2020), thus accounting for the intersectional specificities of political violence.

description: We give a physical derivation of generalized Kahler geometry. Starting from a supersymmetric nonlinear sigma model, we rederive and explain the results of Gualtieri regarding the equivalence between generalized Kahler geometry and the bi-hermitean geometry of Gates-Hull-Rocek. When cast in the language of supersymmetric sigma models, this relation maps precisely to that between the Lagrangian and the Hamiltonian formalisms. We also discuss topological twist in this context.

description: We present new simulations of decaying hydromagnetic turbulence for a relativistic equation of state relevant to the early universe. We compare helical and nonhelical cases either with kinetically or magnetically dominated initial fields. Both kinetic and magnetic initial helicities lead to maximally helical magnetic fields after some time, but with different temporal decay laws. Both are relevant to the early universe, although no mechanisms have yet been identified that produce magnetic helicity with strengths comparable to the big bang nucleosynthesis limit at scales comparable to the Hubble horizon at the electroweak phase transition. Nonhelical magnetically dominated fields could still produce picoGauss magnetic fields under most optimistic conditions. Only helical magnetic fields can potentially have nanoGauss strengths at scales up to 30 kpc today.
