description: The charge $F_1(0)$ and the magnetic $F_2(0)$ form factors of heavy charged leptons have been shown in the framework of the perturbation theory to have imaginary part. The imaginary parts of the form factors for muon and tau lepton have been calculated at the two-loop level in the Standard Model. The effects where these imaginary parts could manifest themselves are discussed.

description: Pairwise comparisons are used in a wide variety of decision situations where the importance of alternatives should be measured on a numerical scale. One popular method to derive the priorities is based on the right eigenvector of a multiplicative pairwise comparison matrix. We consider two monotonicity axioms in this setting. First, increasing an arbitrary entry of a pairwise comparison matrix is not allowed to result in a counter-intuitive rank reversal, that is, the favoured alternative in the corresponding row cannot be ranked lower than any other alternative if this was not the case before the change (rank monotonicity). Second, the same modification should not decrease the normalised weight of the favoured alternative (weight monotonicity). Both properties are satisfied by the geometric mean method but violated by the eigenvector method. The axioms do not uniquely determine the geometric mean. The relationship between the two monotonicity properties and the Saaty inconsistency index are investigated for the eigenvector method via simulations. Even though their violation turns out not to be a usual problem even for heavily inconsistent matrices, all decision-makers should be informed about the possible occurrence of such unexpected consequences of increasing a matrix entry.

description: O presente artigo visa analisar o índice de conforto térmico nos ambientes naturalmente ventilados da Escola Estadual Conselheiro Crispiniano, antigo Ginásio de Guarulhos (1960), projetado pelos arquitetos João Batista Vilanova Artigas e Carlos Cascaldi. Ao longo das décadas, a escola sofreu modificações significativas dentro do lote onde está implantado e em seu entorno, porém manteve suas aberturas originais como única fonte de ventilação natural. Para tal análise, dois modelos de um recorte representativo do edifício foram elaborados a fim de simular momentos diferentes, o as built (1962) e o as is (2021). Os modelos e os dados necessários foram inseridos no programa Energyplus, com base no modelo adaptativo constante na ASHRAE 55-2017. Os resultados mostraram que os índices de conforto térmico mudaram no cenário atual, sendo que, com exceção dos meses de fevereiro e março, o modelo as is apresenta um desempenho inferior ao as built.

description: A simple model for the nonlinear collective transport of interacting particles in a random medium with strong disorder is introduced and analyzed. A finite threshold for the driving force divides the behavior into two regimes characterized by the presence or absence of a steady-state particle current. Below this threshold, transient motion is found in response to an increase in the force, while above threshold the flow approaches a steady state with motion only on a network of channels which is sparse near threshold. Some of the critical behavior near threshold is analyzed via mean field theory, and analytic results on the statistics of the moving phase are derived. Many of the results should apply, at least qualitatively, to the motion of magnetic bubble arrays and to the driven motion of vortices in thin film superconductors when the randomness is strong enough to destroy the tendencies to lattice order even on short length scales. Various history dependent phenomena are also discussed.

description: We have developed a series expansion method for calculating the uniform magnetization, M, as a function of the applied field h for Heisenberg systems at T=0. The method involves introducing Ising anisotropy along the z-axis together with an applied uniform field along the x-axis. On extrapolation to the isotropic limit, one recovers the magnetization for the Heisenberg system with an applied field along the x-axis. This method circumvents the difficulties in developing perturbation theory associated with the commuting nature of the uniform field. The results developed for two-chain ladders appropriate for the material Cu_2(C_5H_{12}N_2)_2Cl_4 are in good agreement with the experimental data. In addition, uniform susceptibility is calculated by high temperature expansions and also compared with the experimental data.

description: What is the upper limit of the mass of the neutralino dark matter whose thermal relic is consistent with the observation? If the neutralino dark matter and colored sparticles are extremely degenerated in mass, with a mass difference less than the QCD scale, the dark matter annihilation is significantly increased and enjoys the "second freeze-out" after the QCD phase transition. In this case, the neutralino dark matter with a mass much greater than 100 TeV can realize the correct dark matter abundance. We study the dark matter abundance and its detection in the case of such highly degenerated mass spectrum of the neutralino dark matter and colored supersymmetric particles.

 General features. The body is elongated oval shaped. Tentacles are wanting. The color of dorsal surface is brownish (Fig. 2a). The length can reach 40 mm. Tentacular and cerebral eyes form two anterior symmetric clusters. The formers are larger and more posterior than cerebral eyes (Fig. 2b). Ventral surface is white and transparent. The ruffled pharynx is visible and shows 12 to 16 lateral folds.
 Reproductive apparatus. Testes are mainly ventral and dispersed between digestive ramifications. They form a small follicles enwrapped each one by e basal membrane. Each testis contains different stages of germs cells (Fig. 2f). Ovaries are less numerous and located mainly in dorsal parenchyma. The seminal vesicle occurs just behind pharyngeal cavity. The main feature of copulatory apparatus is the presence of brown line located in the last third of body which correspond to the cuticularized cirrus. A comb-shaped corrugated surface is present between the two genital pores (Fig. 2c). Two vas deferens lie in both sides of pharynx enter the oval shaped seminal vesicle located behind the pharyngeal cavity. The seminal vesicle is close to ventral wall and communicates with a tubular prostatic vesicle of interpolated type. This vesicle have internal lining provided with radial folds and characterized by a very thick muscular wall consisting of an external layer of longitudinal fibres and a well-developed internal layer of circular fibers. The prostatic vesicle is connected to the eversible cirrus armed with sclerotized spines (Fig. 2d, e).
The vagina is formed by three sections, the vagina externa, the vagina media, and the vagina interna. The former is narrow. The second is known as shell chamber and receive secretions of shell glands. The vagina interna receive the uteri filled with eggs (Fig. 2g).
 Habitat. Four specimens of Echinoplana celerrima were collected from a depth of 20 m. All specimens were found to be associated with the very abundant tunicate Ciona intestinalis. Other associated animals are presented by the sea urchin Paracentrotus lividus (Lamarck, 1816) and the starfish Asterina gibbosa (Pennant, 1777).

Cross Section Fluctuations of Photon Projectile in Generalized Vector Meson Dominance Model

description: We explain that the generalized vector meson dominance (GVMD) model is successful in describing hard high energy processes because it contains expected in QCD Color Coherent Phenomena. Within the model, which reproduces Bjorken scaling and nuclear shadowing for deep inelastic processes, we calculate $P_γ(σ,Q^2)$, the probability for the photon to interact with a target with the cross section $σ$. We find that within the GVMD model the virtual photon has two main components: the ''hard'' one with the small cross section of the order of $1/Q^2$ and the high probability and the ''soft'' one with a typical hadronic cross section with the probability suppressed by the factor of $1/Q^2$. Thus the GVDM model produces $P_γ(σ,Q^2)$ similar to that within the parton model and suggests the conspiracy between hard and soft QCD at $Q^2 > 1$ GeV$^2$. We study the limit $σ\to 0$ and show, that $P_γ(σ,Q^2) \propto 1/ σ$ in both GVMD model and QCD. Thus similarly to the parton model the GVMD model predicts the Color Transparency phenomenon. This is an indirect indication that Bjorken scaling, Color Transparency and shadowing in nuclei in DIS are closely related.

Multifidelity Approximate Bayesian Computation

Subjects: subject: Computation (stat.CO)

description: A vital stage in the mathematical modelling of real-world systems is to calibrate a model's parameters to observed data. Likelihood-free parameter inference methods, such as Approximate Bayesian Computation, build Monte Carlo samples of the uncertain parameter distribution by comparing the data with large numbers of model simulations. However, the computational expense of generating these simulations forms a significant bottleneck in the practical application of such methods. We identify how simulations of cheap, low-fidelity models have been used separately in two complementary ways to reduce the computational expense of building these samples, at the cost of introducing additional variance to the resulting parameter estimates. We explore how these approaches can be unified so that cost and benefit are optimally balanced, and we characterise the optimal choice of how often to simulate from cheap, low-fidelity models in place of expensive, high-fidelity models in Monte Carlo ABC algorithms. The resulting early accept/reject multifidelity ABC algorithm that we propose is shown to give improved performance over existing multifidelity and high-fidelity approaches.

description: In many embedded systems, for instance, in the automotive, avionic, or robotics domain, critical functionalities are implemented via chains of communicating recurrent tasks. To ensure safety and correctness of such systems, guarantees on the reaction time, that is, the delay between a cause (e.g., an external activity or reading of a sensor) and the corresponding effect, must be provided. Current approaches focus on the maximum reaction time, considering the worst-case system behavior. However, in many scenarios, probabilistic guarantees on the reaction time are sufficient. That is, it is sufficient to provide a guarantee that the reaction does not exceed a certain threshold with (at least) a certain probability. This work provides such probabilistic guarantees on the reaction time, considering two types of randomness: response time randomness and failure probabilities. To the best of our knowledge, this is the first work that defines and analyzes probabilistic reaction time for cause-effect chains based on sporadic tasks.

description: Comparing various microscopic theories of rotating superconductors to the conclusions of thermodynamic considerations, we traced their marked difference to the question of how some thermodynamic quantities (the electrostatic and chemical potentials) are related to more microscopic ones: The electron's the work function, mean-field potential and Fermi energy -- certainly a question of general import. After the correct identification is established, the relativistic correction for the London Moment is shown to vanish, with the obvious contribution from the Fermi velocity being compensated by other contributions such as electrostatics and interactions.

description: We address the problem of two-variable causal inference without intervention. This task is to infer an existing causal relation between two random variables, i.e. $X \rightarrow Y$ or $Y \rightarrow X$ , from purely observational data. As the option to modify a potential cause is not given in many situations only structural properties of the data can be used to solve this ill-posed problem. We briefly review a number of state-of-the-art methods for this, including very recent ones. A novel inference method is introduced, Bayesian Causal Inference (BCI), which assumes a generative Bayesian hierarchical model to pursue the strategy of Bayesian model selection. In the adopted model the distribution of the cause variable is given by a Poisson lognormal distribution, which allows to explicitly regard the discrete nature of datasets, correlations in the parameter spaces, as well as the variance of probability densities on logarithmic scales. We assume Fourier diagonal Field covariance operators. The model itself is restricted to use cases where a direct causal relation $X \rightarrow Y$ has to be decided against a relation $Y \rightarrow X$ , therefore we compare it other methods for this exact problem setting. The generative model assumed provides synthetic causal data for benchmarking our model in comparison to existing State-of-the-art models, namely LiNGAM , ANM-HSIC , ANM-MML , IGCI and CGNN . We explore how well the above methods perform in case of high noise settings, strongly discretized data and very sparse data. BCI performs generally reliable with synthetic data as well as with the real world TCEP benchmark set, with an accuracy comparable to state-of-the-art algorithms. We discuss directions for the future development of BCI .

description: We construct the Carrollian equivalent of the relativistic energy--momentum tensor, based on variation of the action with respect to the elementary fields of the Carrollian geometry. We prove that, exactly like in the relativistic case, it satisfies conservation equations that are imposed by general Carrollian covariance. In the flat case we recover the usual non-symmetric energy--momentum tensor obtained using Nœther procedure. We show how Carrollian conservation equations emerge taking the ultra-relativistic limit of the relativistic ones. We introduce Carrollian Killing vectors and build associated conserved charges. We finally apply our results to asymptotically flat gravity, where we interpret the boundary equations of motion as ultra-relativistic Carrollian conservation laws, and observe that the surface charges obtained through covariant phase-space formalism match the ones we defined earlier.

description: Solid dispersions are a promising approach to enhance the dissolution of poorly water-soluble drugs. Solid crystalline formulations show a fast drug dissolution and a high thermodynamic stability. To understand the mechanisms leading to the faster dissolution of solid crystalline formulations, physical mixtures of the poorly soluble drugs celecoxib, naproxen and phenytoin were investigated in the flow through cell (apparatus 4). The effect of drug load, hydrodynamics in the flow through cell and particle size reduction in co-milled physical mixtures were studied. A carrier-and drug-enabled dissolution could be distinguished. Below a certain drug load, the limit of drug load, carrier-enabled dissolution occurred, and above this value, the drug defined the dissolution rate. For a carrier-enabled behavior, the dissolution kinetics can be divided into a first fast phase, a second slow phase and a transition phase in between. This study contributes to the understanding of the dissolution mechanism in solid crystalline formulations and is thereby valuable for the process and formulation development.

description: We present a numerical study of double-diffusive convection characterized by a stratification unstable to thermal convection while at the same time a mean molecular weight (or solute concentration) difference between top and bottom counteracts this instability. Convective zones can form in this case either by the stratification being locally unstable to the combined action of both temperature and solute gradients or by another process, the oscillatory double-diffusive convective instability, which is triggered by the faster molecular diffusivity of heat in comparison with that one of the solute. We discuss successive layer formation for this problem in the case of an instantaneously heated bottom (plate) which forms a first layer with an interface that becomes temporarily unstable and triggers the formation of further, secondary layers. We consider both the case of a Prandtl number typical for water (oceanographic scenario) and of a low Prandtl number (giant planet scenario). We discuss the impact of a Couette like shear on the flow and in particular on layer formation for different shear rates. Additional layers form due to the oscillatory double-diffusive convective instability, as is observed for some cases. We also test the physical model underlying our numerical experiments by recovering experimental results of layer formation obtained in laboratory setups.

description: A minimal SO(10) Higgs structure involving a single adjoint field along with spinors, vectors and singlets has been shown to break the SO(10) gauge symmetry to the standard model while stabilizing the F-flat directions and solving the doublet-triplet splitting problem naturally. With this minimal set of Higgs fields, we show how to construct quark and lepton mass matrices which explain well the many features of the observed spectrum, including the Georgi-Jarlskog mass relations. A large mixing of the muon- and tau-neutrinos results naturally as observed in the atmospheric neutrino data. A particular model relying on a family symmetry has been constructed which realizes the desired mass matrices.

 General features. The worm is of elongated oval shape rounded anteriorly and tiped posteriorly. The dorsal surface is smooth brownish (Fig. 3a). Tubular pharynx is located in the second fourth of body. Usually, the animal protrudes its pharynx as a reaction to fixation. Marginal eyes form a semi circle band located in the anterior part of body (Fig. 3b). Cerebral eyes are larger than marginal ones and form two clusters included in the semi circle formed by the marginal eyes (Fig. 3b). The ventral surface is whitish transparent and shows the tubular muscular pharynx, two genital pores and a well developed sucker located 1mm behind female genital pore.
 Ecol. Mont., 9, 2016, 1-9 Reproductive apparatus. Testes are numerous and are scattered mainly in ventral parenchyma more than dorsal one. The ovaries are bigger in size and lie more or less dorsally. The male gonopore leads to a horizontal male antrum housing the pointed strong stylet (Fig. 3d, e). The usual eosinophilous granulations indicatives of prostatic secretions are observed in the wall around the stylet supported by small penis papillae (Fig. 3e). The latter receive the ejaculatory duct from seminal vesicle and the two prostatic ducts from paired free prostatic vesicles (accessory vesicles) (Fig. 3c). The two vesicles are round muscular bodies with narrow lumen and muscularized wall formed by circular fibres (Fig. 3c).
The main feature of the female genital apparatus is the presence of cement pouch characteristic of sub-order Cotylea (Fig. 3 f). The vagina is oriented vertically and it is connected with two uteri. The sucker is well developed and lies 1 mm behind female genital pore (Fig. 3e).
 Habitat. The single specimen of Prosthiostomum siphunculus was found creeping on a stone from a depth of 29m. The associated fauna included the sea urchin Paracentrotus lividus, the sea cucumber Holothuria (Roweothuria) polii (Delle Chiaje, 1824) and the polychaete Protula tubularia (Montagu, 1803)

description: Manual count of mitotic figures, which is determined in the tumor region with the highest mitotic activity, is a key parameter of most tumor grading schemes. It can be, however, strongly dependent on the area selection due to uneven mitotic figure distribution in the tumor section.We aimed to assess the question, how significantly the area selection could impact the mitotic count, which has a known high inter-rater disagreement. On a data set of 32 whole slide images of H&E-stained canine cutaneous mast cell tumor, fully annotated for mitotic figures, we asked eight veterinary pathologists (five board-certified, three in training) to select a field of interest for the mitotic count. To assess the potential difference on the mitotic count, we compared the mitotic count of the selected regions to the overall distribution on the slide.Additionally, we evaluated three deep learning-based methods for the assessment of highest mitotic density: In one approach, the model would directly try to predict the mitotic count for the presented image patches as a regression task. The second method aims at deriving a segmentation mask for mitotic figures, which is then used to obtain a mitotic density. Finally, we evaluated a two-stage object-detection pipeline based on state-of-the-art architectures to identify individual mitotic figures. We found that the predictions by all models were, on average, better than those of the experts. The two-stage object detector performed best and outperformed most of the human pathologists on the majority of tumor cases. The correlation between the predicted and the ground truth mitotic count was also best for this approach (0.963 to 0.979). Further, we found considerable differences in position selection between pathologists, which could partially explain the high variance that has been reported for the manual mitotic count.

description: Nitriles are versatile and highly desired chemical intermediates for a range of products. Their economic large-scale production requires highly efficient and selective synthesis. The nickel- catalyzed hydrocyanation of C=C double bonds provides such selective and 100% atom-economical access to nitriles, but the catalysts hitherto lack activity and longevity. Yet, the literature focusing on increased catalytic activity or optimized operational procedures is scarce, at the least. Here, we present a thorough investigation and optimization of operational procedures using a commercially available diphosphite ligand and styrene as a model substrate. This led us to achieve a TOF20 of more than 300,000 h−1.

Corrections to the universal behavior of the Coulomb-blockade peak splitting for quantum dots separated by a finite barrier

description: Building upon earlier work on the relation between the dimensionless interdot channel conductance g and the fractional Coulomb-blockade peak splitting f for two electrostatically equivalent dots, we calculate the leading correction that results from an interdot tunneling barrier that is not a delta-function but, rather, has a finite height V and a nonzero width xi and can be approximated as parabolic near its peak. We develop a new treatment of the problem for g much less than 1 that starts from the single-particle eigenstates for the full coupled-dot system. The finiteness of the barrier leads to a small upward shift of the f-versus-g curve at small values of g. The shift is a consequence of the fact that the tunneling matrix elements vary exponentially with the energies of the states connected. Therefore, when g is small, it can pay to tunnel to intermediate states with single-particle energies above the barrier height V. The correction to the zero-width behavior does not affect agreement with recent experimental results but may be important in future experiments.

description: The chaotic mixing by random two-body interactions of many-electron Fock states in a confined geometry is investigated numerically and compared with analytical predictions. Two distinct regimes are found in the dependence of the inverse participation ratio in Fock space I on the dimensionless conductance of the quantum dot g and the excitation energy E. In both regimes I>>1, but only the small-g regime is described by the golden rule. The crossover region is characterized by a maximum in a scaling function that becomes more pronounced with increasing excitation energy. The scaling parameter that governs the transition is (E/g)ln g.

description: Since 2019, the Mason Library's Center for Research & Writing provides library research services and writing tutoring to undergraduate students and instructors across the curriculum. Staffed by twelve to fifteen undergraduate Research & Writing Tutors, they teach workshops in classes on library research and writing topics, meet one-on-one with students for consultations, staff the drop-in Research & Writing Help Desk, and participate in continuous professional development and training. With only three faculty librarians staffing our library serving 2700 undergraduates and over 300 instructors, the Research & Writing Tutors are essential to providing front-line library services. Adopting a peer-to-peer model has significantly altered the way library services are provided, service data is gathered, and the ways librarians work with students and faculty. In this presentation I'll answer the most commonly asked questions about our fully integrated service model. I'll share specifics about the curriculum in our training course, Tutoring Research & Writing, and our journey trying various models of training before we developed the course in 2019. Pulling from information and library science literature, writing center studies, information literacy, and composition studies students in the course are encouraged to consider the integration between research and writing processes and to develop their skills to help other students with research and writing. While concepts of privacy and confidentiality, and working with all learners has always been included in our training, increasingly, our curriculum focuses on developing skills such as boundary setting and assertiveness, supporting students in distress, and working with neurodiverse students and universal design principles. This presentation offers library administration, librarians, and writing center professionals ideas for beginning to integrate services and an example curriculum for training of undergraduate peer tutors of research and writing. Participants will consider pros and cons of the model and what may or may not work at their institution.

description: Model discrimination identifies a mathematical model that usefully explains and predicts a given system's behaviour. Researchers will often have several models, i.e. hypotheses, about an underlying system mechanism, but insufficient experimental data to discriminate between the models, i.e. discard inaccurate models. Given rival mathematical models and an initial experimental data set, optimal design of experiments suggests maximally informative experimental observations that maximise a design criterion weighted by prediction uncertainty. The model uncertainty requires gradients, which may not be readily available for black-box models. This paper (i) proposes a new design criterion using the Jensen-Rényi divergence, and (ii) develops a novel method replacing black-box models with Gaussian process surrogates. Using the surrogates, we marginalise out the model parameters with approximate inference. Results show these contributions working well for both classical and new test instances. We also (iii) introduce and discuss GPdoemd, the open-source implementation of the Gaussian process surrogate method.
Langevin Simulations of Two Dimensional Vortex Fluctuations: Anomalous Dynamics and a New $IV$-exponent

description: The dynamics of two dimensional (2D) vortex fluctuations are investigated through simulations of the 2D Coulomb gas model in which vortices are represented by soft disks with logarithmic interactions. The simulations trongly support a recent suggestion that 2D vortex fluctuations obey an intrinsic anomalous dynamics manifested in a long range 1/t-tail in the vortex correlations. A new non-linear IV-exponent a, which is different from the commonly used AHNS exponent, a_AHNS and is given by a = 2a_AHNS - 3, is confirmed by the simulations. The results are discussed in the context of earlier simulations, experiments and a phenomenological description.

description: While the demand as well as interest for long-term preservation and open access to research data is growing, ensuring this is a challenge shared across the scientific community. Researchers find themselves often confronted with questions such as: Where can I find or publish research data? Which possibilities and responsibilities do I have if I want to make my own data available? And how do I find a repository that best fits my data and needs?

Charlotte Neidiger from the Karlsruhe Institute of Technology (KIT) will present one tool to tackle this challenge in the form of the "re3data" service, a global registry of research data repositories across all academic disciplines that promotes a culture of sharing, increased access and better visibility of research data. The talk will highlight the service's foundational principles, functionality and usage, as well as provide tips and tricks for efficient utilization.
