description: In this work we report the calculation of the total cross section for pion-production by the dispersion of neutrinos on nucleons. We use a consistent formalism for the intermediate resonance states of spin $3/2$ , taking care on the conditions imposed by the invariance on contact transformations and using the Sachs parametrization for the form factors. In addition, we incorporate states in the second resonance region up to 1.6 GeV and implement different approaches for all the dressed resonance propagators. In addition to the $Δ$(1232), we include the N$^*$(1440),N$^*$(1535)and N$^*$(1520) resonance contributions, and it is shown that this inclusion improve the description of the total cross section regards a model where only the $Δ$(1230) resonance is considered. Also results for antineutrinos are properly described.

Crossover from the vortex state to the Fulde-Ferrell-Larkin-Ovchinnikov state in quasi-two-dimensional superconductors

description: We examine the coexistence of the vortex state and the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state in quasi-two-dimensional type-II superconductors and the crossover from the coexistence state to the pure FFLO state when the Maki parameter αincreases. The pure FFLO state, characterized by finite center-of-mass momenta q \ne 0 of Cooper pairs occurs in the two-dimensional limit, when the magnetic field is parallel to the conductive plane. The vectors q are determined from the Fermi-surface structure and pairing anisotropy, and become finite below a temperature T^*. In quasi-two-dimensions, because of the orbital pair-breaking effect, the coexistence state characterized by (n,q//) occurs, where n and q// denote the Landau level index of the vortex state and the wave number of the additional FFLO modulation along the magnetic field. We obtain the αdependence of the upper critical field by numerical calculations. The upper critical field exhibits a cascade curve in the H-T phase diagram. It is analytically shown that n diverges in the two-dimensional limit α\to \infty below T^*. In this limit, the upper critical field equation of the coexistence state is reduced to that of the FFLO state. A relation between n of the coexistence state and q_{\perp} of the pure FFLO state is obtained, where q_{\perp} denotes the component of q perpendicular to the magnetic field. It is found that the pure FFLO state is nothing but the vortex state with infinitely large n as is known in two-dimensional superconductors in a tilted magnetic field. The vortex state with large n can be regarded as the FFLO state with non-zero q_{\perp} in three dimensions.

description: In this study the results of redistribution of forces for bolt connections are presented. The main attention is focused to the shear forces in the bolt, creating a bending moment on the beam supports. Analyzing that can reveal patterns of behavior of the connection depending on the load and the number of bolts. Accounting compliance units can reduce the number of materials used and make design process more detail. Thus, the main objective of this research was a more detailed study of compliance in the design process in order to apply the acquired knowledge into practice.

description: We study the thermal expansion of chains formed by self-assembly of magnetic colloidal particles in a magnetic field. Using video-microscopy, complete positional data of all the particles of the chains is obtained. By changing the ionic strength of the solution and the applied magnetic field, the interaction potential can be tuned. We analyze the thermal expansion of the chain using a simple model of a one dimensional anharmonic crystal of finite size.

description: We present results from the first cosmological simulations which study the onset of primordial, metal-free (population III), cosmic star formation and the transition to the present-day, metal-rich star formation (population II-I), including molecular (H$_2$, HD, etc.) evolution, tracing the injection of metals by supernovæ into the surrounding intergalactic medium and following the change in the initial stellar mass function (IMF) according to the metallicity of the corresponding stellar population. Our investigation addresses the role of a wide variety of parameters (critical metallicity for the transition, IMF slope and range, SN/pair-instability SN metal yields, star formation threshold, resolution, etc.) on the metal-enrichment history and the associated transition in the star formation mode. All simulations present common trends. Metal enrichment is very patchy, with rare, unpolluted regions surviving at all redshifts, inducing the simultaneous presence of metal-free and metal-rich star formation regimes. As a result of the rapid pollution within high-density regions due to the first SN/pair-instability SN, local metallicity is quickly boosted above the critical metallicity for the transition. The population III regime lasts for a very short period during the first stages of star formation ($\sim 10^7\,\rm yr$), and its average contribution to the total star formation rate density drops rapidly below $\sim 10^{-3}-10^{-2}$.

description: We here present a systematic study on the concept of ecological niche. Ecological niche has been described in various ways; from habitat to role and from biotope to hypervolume. Although it has many different definitions, it remains one of the most fundamental concepts in Ecology. Our aim is to implement the Research Weaving framework on a large body of literature, relevant to the ecological niche in order to illustrate how this concept evolved since its introduction in the early 20th century. We analysed over 29,000 publications using systematic maps and bibliometric webs. Our synthesis consisted of 8 components: phylogeny, type/validity, temporal trends, spatial patterns, contents, terms, authors, citations. We used bibliometric analyses, quantitative analyses of publication metadata and text mining algorithms. This integrative presentation of the development of the ecological niche concept provides an overview of how dynamics changed over time. It also allows us to detect knowledge gaps, while presenting a systematic summary of existing knowledge. To our knowledge, this is one of the first projects that implements the research weaving framework using exclusively automated processes.

Characterizing black hole variability with nonlinear methods: the case of the X-ray Nova 4U 1543-47

description: We investigate the possible nonlinear variability properties of the black hole X-ray nova 4U1543-47 to complement the temporal studies based on linear techniques, and to search for signs of nonlinearity in Galactic black hole (GBH) light curves. First, we apply the weighted scaling index method (WSIM) to characterize the X-ray variability properties of 4U1543-47 in different spectral states during the 2002 outburst. Second, we use surrogate data to investigate whether the variability is nonlinear in any of the different spectral states. The main findings can be summarized as follows. The mean weighted scaling index appears to be able to parametrize uniquely the temporal variability properties of this GBH: the 3 different spectral states of the 2002 outburst of 4U1543-47 are characterized by different and well constrained values. The search for nonlinearity reveals that the variability is linear in all light curves with the notable exception of the very high state. Our results imply that we can use the WSIM to assign a single number, namely the mean weighted scaling index, to a light curve, and in this way discriminate among the different spectral states of a source. The detection of nonlinearity in the VHS, that is characterized by the presence of most prominent QPOs, suggests that intrinsically linear models which have been proposed to account for the low frequency QPOs in GBHs may be ruled out (abridged).

description: We describe here recent inelastic neutron scattering experiments on the heavy fermion compound URu2Si2 realized in order to clarify the nature of the hidden order (HO) phase which occurs below T_0 = 17.5 K at ambient pressure. The choice was to measure at a given pressure P where the system will go, by lowering the temperature, successively from paramagnetic (PM) to HO and then to antiferromagnetic phase (AF). Furthermore, in order to verify the selection of the pressure, a macroscopic detection of the phase transitions was also achieved in situ via its thermal expansion response detected by a strain gauge glued on the crystal. Just above P_x = 0.5 GPa, where the ground state switches from HO to AF, the Q_0 = (1, 0, 0) excitation disappears while the excitation at the incommensurate wavevector Q_1 = (1.4, 0, 0) remains. Thus, the Q_0 = (1, 0, 0) excitation is intrinsic only in the HO phase. This result is reinforced by studies where now pressure and magnetic field $H$ can be used as tuning variable. Above P_x, the AF phase at low temperature is destroyed by a magnetic field larger than H_AF (collapse of the AF Q_0 = (1, 0, 0) Bragg reflection). The field reentrance of the HO phase is demonstrated by the reappearance of its characteristic Q_0 = (1, 0, 0) excitation. The recovery of a PM phase will only be achieved far above H_AF at H_M approx 35 T. To determine the P-H-T phase diagram of URu2Si2, macroscopic measurements of the thermal expansion were realized with a strain gauge. The reentrant magnetic field increases strongly with pressure. Finally, to investigate the interplay between superconductivity (SC) and spin dynamics, new inelastic neutron scattering experiments are reported down to 0.4 K, far below the superconducting critical temperature T_SC approx 1.3 K as measured on our crystal by diamagnetic shielding.

description: For soft continuum arms, visual servoing is a popular control strategy that relies on visual feedback to close the control loop. However, robust visual servoing is challenging as it requires reliable feature extraction from the image, accurate control models and sensors to perceive the shape of the arm, both of which can be hard to implement in a soft robot. This letter circumvents these challenges by presenting a deep neural network-based method to perform smooth and robust 3D positioning tasks on a soft arm by visual servoing using a camera mounted at the distal end of the arm. A convolutional neural network is trained to predict the actuations required to achieve the desired pose in a structured environment. Integrated and modular approaches for estimating the actuations from the image are proposed and are experimentally compared. A proportional control law is implemented to reduce the error between the desired and current image as seen by the camera. The model together with the proportional feedback control makes the described approach robust to several variations such as new targets, lighting, loads, and diminution of the soft arm. Furthermore, the model lends itself to be transferred to a new environment with minimal effort.

A Shrinking Path for Bicycles
Creators: name: Wang, Qiuning
Publisher: name: The University of British Columbia

description: Beijing formerly had a strong tradition of cycling that exceeded many other Chinese cities in both ownership and ridership. Over the past two decades, however, this tradition has been on a shrinking path. During the mid 1980s, when China was called the ―Kingdom of Bicycle‖, Beijing had a biking population of over eight million (Sit, 1996a), with 62.7% of all trips being made by bicycle (BTRC, 2011). By 2000, despite bicycle ownership remaining high, only 38.7% of all trips were made by bicycle, this number dropping even lower to 16.7% of all trips in 2010 (BTRC, 2011). What were the factors that made cycling so popular in the past and what deters it currently? Through a historical review and an analysis of the national and local statistical data, my research aims to (1) provide an overview of the cycling history in Beijing; (2) identify and analyze the major factors which have influenced bicycle use in different periods; and (3) propose policy recommendations based on the improved understanding about the determinants of bicycle use in Beijing. This research covers a historical time frame of a century, which are categorized into four periods representing different stages of bicycle use in Beijing: (1) the early adoption of bicycle use from 1910 to 1949; (2) the period of steady growth in bicycle use from 1950 to 1978; (3) the period of rapid growth in bicycle use from 1979 to the 1990s; and (4) the period of decline in bicycle use from the 1990s to current day. Among various factors contributing to the rise and fall of bicycle use in Beijing, four of them have been identified as having the greatest impact: policy and regulation, built environment, the bicycle industry, and social-economic conditions. Through the investigation of these factors using a mixed method approach, the research reveals the following conclusions: (1) the historically inherited grid street network and the low height, high-density housing form contains fundamental features amenable to cycling; (2) the integration of non-motorized modes to the road network in the pre-and-early reform period, a growing bicycle industry and the moderately increased income pre-1990 were the major contributing factors to the thriving bicycle use in the 1980s and 1990s; (3) the launch of the National Automobile Industry Policy in 1994 had a detrimental impact on bicycle use and marked the beginning of a dramatic decline in bicycle use in Beijing; (4) the city‘s current transportation planning not only lacks a real interest in sustaining the tradition of cycling in Beijing, but also lacks a clear target and an integrated approach of reviving the bicycle use among its citizens; and (5) the strong existing bicycle industry, the remaining high level of bicycle ownership iii among Beijing residents, and the generous road network in the city provide concrete grounds for a more progressive bicycle planning policy.

description: In Ba(Fe0.95Co0.05)2As2 all of the 75As NMR intensity at the paramagnetic resonance position vanishes abruptly below Tonset(SDW)=56 K, indicating that magnetic (spin density wave) order is present in all of the sample volume, despite bulk superconductivity below Tc=15 K. The two phases thus coexist homogeneously at the microscopic scale. In Ba0.6K0.4Fe2As2, on the other hand, the signal loss below Tonset(SDW)~75 K is not complete, revealing that magnetic order is bound to finite-size areas of the sample, while the remaining NMR signal shows a clear superconducting response below Tc=37 K. Thus, the two phases are not homogeneously mixed, at least for this potassium concentration. For both samples, spatial electronic and/or magnetic inhomogeneity is shown to characterize the NMR properties in the normal state.

description: Meta-analyses are costly to conduct, often impossible to reanalyze, and outdated as soon as a new study emerges. How can we lower these hurdles, make data more accessible to researchers, and transform meta-analyses into a living resource? MetaLab (https://metalab.stanford.edu/) is an interactive platform that hosts community-augmented meta-analyses in the field of developmental psychology. On MetaLab, community members can contribute full datasets or update existing meta-analyses. To ensure that new records comply with our format and to make automatic processing possible, we provide a validator using a graphical user interface (GUI). This greatly facilitates the continuous growth of MetaLab and ensures that data contributors can almost instantly benefit from the rich infrastructure we provide. To allow an even broader range of researchers to leverage meta-analytic data, our interactive visualization and power analysis tools allow exploring meta-analytic datasets and planning future experiments using the best evidence available. We will provide a tour of these tools to demonstrate how contributing, updating, and exploring a meta-analysis is greatly facilitated through our GUI.

description: The utilisation of automated classification tools from the field of Natural Language Processing (NLP) can massively decrease the amount of time required for the article screening stage of evidence synthesis. To achieve high accuracy, models often require huge volumes of ‘gold-standard’ labelled training data, which can be expensive and time-consuming to produce. As a result, ‘transfer learning’, in which NLP models, pre-trained on large corpora, are downloaded and finetuned on a smaller number of hand-labelled texts, is an increasingly popular method for achieving high-performance text classification. The availability of state-of-the-art transformer models via the open source ‘hugging face’ library has also improved the accessibility of this approach. However, materials outlining how to make use of such resources in R are limited. At ESMARCONF 2022, I will introduce and demonstrate how transfer learning can be carried out in R and seamlessly integrated with data collection from academic databases and internet sources.
Relativistic Suppression of Black Hole Recoils

description: Numerical-relativity simulations indicate that the black hole produced in a binary merger can recoil with a velocity up to v_max ~ 4,000 km/s with respect to the center of mass of the initial binary. This challenges the paradigm that most galaxies form through hierarchical mergers, yet retain supermassive black holes at their centers despite having escape velocities much less than v_max. Interaction with a circumbinary disk can align the binary black hole spins with their orbital angular momentum, reducing the recoil velocity of the final black hole produced in the subsequent merger. However, the effectiveness of this alignment depends on highly uncertain accretion flows near the binary black holes. In this Letter, we show that if the spin S_1 of the more massive binary black hole is even partially aligned with the orbital angular momentum L, relativistic spin precession on sub-parsec scales can align the binary black hole spins with each other. This alignment significantly reduces the recoil velocity even in the absence of gas. For example, if the angle between S_1 and L at large separations is 10 degrees while the second spin S_2 is isotropically distributed, the spin alignment discussed in this paper reduces the median recoil from 864 km/s to 273 km/s for maximally spinning black holes with a mass ratio of 9/11. This reduction will greatly increase the fraction of galaxies retaining their supermassive black holes.

Galactic center gamma-ray production by cosmic rays from stellar winds and Sgr A East

description: The High Energy Stereoscopic System (HESS), the Major Atmospheric Gamma-ray Imaging Cherenkov Telescope (MAGIC), and the Very Energetic Radiation Imaging Telescope Array System (VERITAS) have observed diffuse gamma-ray emission strongly correlated with the central molecular zone in the Galactic center. The most accepted scenario to generate this emission is via a hadronic interaction between cosmic rays (CRs) and ambient gas, where CRs are accelerated from a central and continuous source of 1 PeV protons (PeVatron). We explore the influence of the three-dimensional (3D) shape of the central molecular zone on the indirect observation of the CR energy density via gamma-ray detection. We simulated synthetic gamma-ray maps using a CR diffusion model with spherical injection, one isotropic diffusion coefficient, no advection, and mono-energetic particles of 1 PeV. Also, we used two different 3D gas distributions considering the observed gas column density, both with and without an inner cavity. We find that when using a persistent CR source, a disk-like gas distribution is needed to reproduce the existing CR indirect observations. This is in agreement with the continuous gas distribution implied by some dynamical models and studies based on the comparison of emission and absorption molecular lines. However, it contradicts several models of the central molecular zone, which imply that this structure has a significant inner cavity. This tension can be reconciled by an additional, impulsive CR injection. If the central molecular zone has a cavity, a composite CR population, coming from the stellar winds of the Wolf-Rayet stars in the central 0.5 pc and the supernova Sgr A East, produces a good match to the observed gamma-ray morphology in the Galactic center.
