 The ultimate aim of field courses should be to enable students to work autonomously in the field. Student- and problem-centered approaches to learning in the field afford students much autonomy, but unlike in the more traditional show-and-tell approach, independent projects have so far required that students spend a significant amount of time working in the field without access to supervision. Unless students are competent enough to experience proficiency and a feeling of controlling the quality of their own work, such autonomy is detrimental to student motivation. We developed a knowledge-based tutoring system, the Utrecht Companion to the Earth, that allows an integrated asynchronous online supervision of students’ field activities. In other words, the student’s smartphone or tablet becomes their just-in-time field instructor. The system allows us to make available learning materials in different formats, such as infographics, checklists, quizzes, or knowledge clips. These materials are presented on a cartographic background that can be toggled between a topographic and geological map. The intended outcome of adopting our system in field courses is a richer learning environment in which students learn more, achieve higher-order learning outcomes, and experience feelings of proficiency by having a more productive interaction with earth structures and materials. The learning materials meet the immediate need of a student exactly when it arises allowing them to acquire knowledge and skills. Face-to-face time in the field with an instructor can then be used to achieve higher-order learning outcomes, focusing not on acquiring knowledge, but on gaining insight and understanding.

description: In this paper we analyze the effect of the bulk-mediated excursions (BME) of reactive species on the long-time behavior of the catalytic Langmuir-Hinshelwood-like A + B \to 0 reactions in systems in which a catalytic plane (CP) is in contact with liquid phase, containg concentrations of reactive particles. Such BME result from repeated particles desorption from the CP, subsequent diffusion in the liquid phase and eventual readsorption on the CP away from the intial detachment point. This process which leads to an effective superdiffusive transport along the CP. We consider both "batch" reactions, in which all particles of reactive species were initially adsorbed onto the CP, and reactions followed by a steady inflow of particles onto the CP. We show that for "batch" reactions the BME provide an effective mixing channel and here the mean-field-type behavior emerges. On contrary, for reaction followed by a steady inflow of particles, we observe essential departures from the mean-field behavior and find that the mixing effect of the BME is insufficient to restore chemical equilibrium. We show that a steady-state is established as t \to \infty, in which the limiting value of the mean coverages of the CP depends on the particles' diffusion coefficient in the bulk liquid phase and the spatial distributions of adsorbed particles are strongly correlated. Moreover, we show that the relaxation to such a steady-state is described by a power-law function of time, in contrast to the exponential time-dependence describing the approach to equilibrium in perfectly stirred systems.

description: Firm location decisions are typically influenced by economic, demographic, environmental, and social factors. This research extends the current literature by investigating the factors thought to influence the total number of manufacturing firms within a given region. Given the large number of regions without any manufacturing firms, a double hurdle model is employed to account for excess zeros. The results suggest that there are certain industry input variables, such as population and education that make a region an attractive or unattractive location for a particular manufacturing firm.
Did Proximity to Ports Have Any Bearing on Urban Growth between 1970 and 2000?

description: The major goal of the research presented here is to test the usefulness of a different way of conceptualizing broad regions of the United States. The census regions are often used to group MSAs for various types of studies. The alternative regions are defined based on access to ocean, Great Lakes, or river ports. The usefulness of this set of regions is compared to that of the census regions using both a dummy variable approach and an index of disparity approach. This paper presents a statistical test of the hypothesis that access to port facilities could and did positively influence urban growth between 1970 and 1990. The rationale for the hypothesis is that the expansion of trade resulting from the North American Free Trade Association, various steps accomplished under GATT and the WTO, and the United States' leading role as a free trade advocate has increased the advantage of expanding economic activity in coastal regions.

description: Utrecht University, the Netherlands, The Netherlands

 In order to improve student learning during lectures on location, students can be actively engaged by giving short class-exercises. Class exercises are just one of the many ways of making lectures more interactive. A good source of inspiration regarding interactive lectures is formed by the quick start-up guides presented at https://serc.carleton.edu/onramps/index.html (NSF funded project). I have ample experience with class exercises in a Structural Geology and Tectonics course I teach at Utrecht University. This is a 3rd year bachelor’s degree course with 20–40 participants. I typically give two class exercises per lecture hour. They always have a well-defined aim and task, and take about 3–10 minutes each. The exercises bring back the attention of students, re-emphasize a topic that I have just talked about, and give the students a chance to directly apply a concept, equation, or technique. The exercises may include a quick calculation, making a measurement, reading a graph, or interpreting a (seismic) section or rock (micro)structure. Course evaluations show that students very much appreciate the interactive nature of the lectures induced by the class exercises. They feel engaged and later revisit the exercises in preparation for exams. In my experience, class exercises are not widely used as a useful teaching strategy, which is a regrettable since they are easy to implement and form a cost-effective way to make classic lectures more effective for students in terms of reaching learning outcomes.

description: The lack of consistent, reliable data on interregional trade and interindustry transactions hampers complete analysis of regional models. This study implements and tests interindustry transaction flows in a national system of economic regions derived from an interregional accounting framework and initial information on interregional shipments. The method used to construct an interregional Commodity by Industry Flow matrix for the United States involves the construction of single-state SAMs. The interregional flows connecting states are estimated using a method based on the Commodity Flow Survey data published by the Bureau of Transportation Statistics, which adjusts the estimated interregional SAM to insure the integrity of intraregional and system-wide, national accounts. This paper presents the results of exercises testing the validity of the resulting interregional trade-flow data using, among other data sources, the CFS itself, the FAFD and S&P/DRI regional estimates. The model is tested is a US interregional framework describing flows within and among the 50 states and the District of Colombia.

description: The interstellar medium is a multi-phase, magnetized, and highly turbulent medium. In this paper, we address both theoretical and observational aspects of plasma turbulence in the interstellar medium. We successively consider radio wave propagation through a plasma and radio polarized emission. For each, we first provide a theoretical framework in the form of a few basic equations, which enable us to define useful diagnostic tools of plasma turbulence; we then show how these tools have been utilized to detect and interpret observational signatures of plasma turbulence, and what astronomers have learned from them regarding the nature, the sources, and the dissipation of turbulence in the interstellar medium.

A twin convolutional neural network (CNN) architecture is designed and it is fed with the received pilot signals to estimate both direct and cascaded channels. In a multi-user scenario, each user has access to the CNN to estimate its own channel. The performance of the proposed DL approach is evaluated and compared with state-of-the-art DL-based techniques and its superior performance is demonstrated.

description: We present a combined experimental and theoretical study of submonolayer heteroepitaxial growth of Ag on Si(111)-7x7 at temperatures from 420 K to 550 K when Ag atoms can easily diffuse on the surface and the reconstruction 7x7 remains stable. STM measurements for coverages from 0.05 ML to 0.6 ML show that there is an excess of smallest islands (each of them fills up just one half-unit cell - HUC) in all stages of growth. Formation of 2D wetting layer proceeds by continuous nucleation of the smallest islands in the proximity of larger 2D islands (extended over several HUCs) and following coalescence with them. Such a growth scenario is verified by kinetic Monte Carlo simulation which uses a coarse-grained model based on a limited capacity of HUC and a mechanism which increases nucleation probability in a neighbourhood of already saturated HUCs (correlated nucleation). The model provides a good fit for experimental dependences of the relative number of Ag-occupied HUCs and the preference in occupation of faulted HUCs on temperature and amount of deposited Ag. Parameters obtained for the hopping of Ag adatoms between HUCs agree with those reported earlier for initial stages of growth. The model provides two new parameters - maximum number of Ag atoms inside HUC, and on HUC boundary.

description: We analyze the ground-state energy, local spin correlation, impurity spin polarization, impurity-induced magnetization, and corresponding zero-field susceptibilities of the symmetric single-impurity Kondo model on a tight-binding chain with bandwidth $W=2{\cal D}$ and coupling strength $J_{\rm K}$. We compare perturbative results and variational upper bounds from Yosida, Gutzwiller, and first-order Lanczos wave functions to the numerically exact data obtained from the Density-Matrix Renormalization Group (DMRG) and from the Numerical Renormalization Group (NRG) methods. The Gutzwiller variational approach becomes exact in the strong-coupling limit and reproduces the ground-state properties from DMRG and NRG for large couplings. We calculate the impurity spin polarization and its susceptibility in the presence of magnetic fields that are applied globally/locally to the impurity spin. The Yosida wave function provides qualitatively correct results in the weak-coupling limit. In DMRG, chains with about $10^3$ sites are large enough to describe the susceptibilities down to $J_{\rm K}/{\cal D}\approx 0.5$. For smaller Kondo couplings, only the NRG provides reliable results for a general host-electron density of states $ρ_0(ε)$. To compare with results from Bethe Ansatz, we study the impurity-induced magnetization and zero-field susceptibility. For small Kondo couplings, the zero-field susceptibilities at zero temperature approach $χ_0(J_{\rm K}\ll {\cal D})/(gμ_{\rm B})^2\approx \exp[1/(ρ_0(0)J_{\rm K})]/(2C{\cal D}\sqrt{πe ρ_0(0)J_{\rm K}})$, where $\ln(C)$ is the regularized first inverse moment of the density of states. Using NRG, we determine the universal sub-leading corrections up to second order in $ρ_0(0)J_{\rm K}$.

description: The Geneva evolutionary code has been modified to study the advanced stages (Ne, O, Si burnings) of rotating massive stars. Here we present the results of four 20 solar mass stars at solar metallicity with initial rotational velocities of 0, 100, 200 and 300 km/s in order to show the crucial role of rotation in stellar evolution. As already known, rotation increases mass loss and core masses (Meynet and Maeder 2000). A fast rotating 20 solar mass star has the same central evolution as a non-rotating 26 solar mass star. Rotation also increases strongly net total metal yields. Furthermore, rotation changes the SN type so that more SNIb are predicted (see Meynet and Maeder 2003 and N. Prantzos and S. Boissier 2003). Finally, SN1987A-like supernovae progenitor colour can be explained in a single rotating star scenario.

description: We report quantum Monte Carlo (stochastic series expansion) results for the transition from a Mott insulator to a dimerized Peierls insulating state in a half-filled, 1D extended Hubbard model coupled to optical bond phonons. Using electron-electron (e-e) interaction parameters corresponding approximately to polyacetylene, we show that the Mott-Peierls transition occurs at a finite value of the electron-phonon (e-ph) coupling. We discuss several different criteria for detecting the transition and show that they give consistent results. We calculate the critical e-ph coupling as a function of the bare phonon frequency and also investigate the sensitivity of the critical coupling to the strength of the e-e interaction. In the limit of strong e-e couplings, we map the model to a spin-Peierls chain and compare the phase boundary with previous results for the spin-Peierls transition. We point out effects of a nonlinear spin-phonon coupling neglected in the mapping to the spin-Peierls model.

description: We study a nonlocal theory that combines both the Pseudo quantum electrodynamics (PQED) and Chern-Simons actions among two-dimensional electrons. In the static limit, we conclude that the competition of these two interactions yields a Coulomb potential with a screened electric charge given by $e^2/(1+θ^2)$, where $θ$ is the dimensionless Chern-Simons parameter. This could be useful for describing the substrate interaction with two-dimensional materials and the doping dependence of the dielectric constant in graphene. In the dynamical limit, we calculate the effective current-current action of the model considering Dirac electrons. We show that this resembles the electromagnetic and statistical interactions, but with two different overall constants, given by $e^2/(1+θ^2)$ and $e^2θ/(1+θ^2)$. Therefore, the $θ$-parameter does not provide a topological mass for the Gauge field in PQED, which is a relevant difference in comparison with quantum electrodynamics. Thereafter, we apply the one-loop perturbation theory in our model. Within this approach, we calculate the electron self-energy, the electron renormalized mass, the corrected gauge-field propagator, and the renormalized Fermi velocity for both high- and low-speed limits, using the renormalization group. In particular, we obtain a maximum value of the renormalized mass for $θ\approx 0.36$. This behavior is an important signature of the model and relations with doping control of band gap size are also discussed in the conclusions.

description: We measured the far infrared reflectivity of two superconducting Pr(2-x)Ce(x)CuO(4) films above and below Tc. The reflectivity in the superconducting state increases and the optical conductivity drops at low energies, in agreement with the opening of a (possibly) anisotropic superconducting gap. The maximum energy of the gap scales roughly with Tc as 2 Delta_{max} / kB Tc ~ 4.7. We determined absolute values of the penetration depth at 5 K as lambda_{ab} = (3300 +/- 700) A for x = 0.15 and lambda_{ab} = (2000 +/- 300) A for x = 0.17. A spectral weight analysis shows that the Ferrell-Glover-Tinkham sum rule is satisfied at conventional low energy scales \~ 4 Delta_{max}.

description: For all n > 0 there is a homomorphism from the smooth concordance group of knots in dimension 2n + 1 to an algebraically defined group called the rational algebraic concordance group. This algebraic concordance group splits as a direct sum of groups indexed by polynomials. For n > 1 the homomorphism is injective. This leads to what is called a primary decomposition theorem for knot concordance. In the classical dimension, the kernel of this homomorphism includes the smooth concordance group of topologically slice knots, and Jae Choon Cha has begun studying possible primary decompositions of this subgroup. Here we will show that primary decompositions of a strong type cannot exist. In more detail, it is shown that there exists a topologically slice knot K for which there is a factorization of its Alexander polynomial as f(t)g(t), where f(t) and g(t) are relatively prime and each is the Alexander polynomial of a topologically slice knot, but K is not smoothly concordant to any connected sum of a pair of knots with Alexander polynomials f(t) and g(t).

title: Fractures, fluids and hypogenic karsts: key features in carbonate reservoirs and aquifers

 Karsts have been documented in a large number of hydrocarbon reservoirs but their origin has generally been attributed to meteoric processes. In the last years, however, it has been increasingly recognized that many of them have a hypogenic origin which implies that the CO2 and/or H2S responsible for carbonate dissolution come from deep sources transport being favoured by upward flow of hot fluids. These cavities can be meter to few tens of meters large, therefore being below the resolution power of seismic studies; they are often associated with large dolomitized bodies and the occurrence of silicified rocks, as well as the presence of exotic minerals such as barite. Similar features are being identified in carbonate successions targeted for geothermal heat extraction. Tools are needed to predict the distribution and geometry of these karsts and, eventually to implement them in reservoir simulators. In this contribution we report on the extensive work we have performed in caves developed in Neoproterozoic, generally tight carbonates of the Salitre Formation (Irece basin, Bahia state, Brazil). Integrating portable LiDAR modelling with structural and petrographic study we we propose a model for the development of these large-scale dissolution features. Fluids responsible for the formation of the hypogenic caves were expelled from the base of the Braziliano orogeny and/or during subsequent exhumation and experienced long-range migration towards the foreland along regional aquifers. Once flow encountered steep features such as strike-slip or thrust faults, hot aggressive fluids started moving upward along the fault zone and/or related fracture corridors. If upward flow became prevented by the presence of an impermeable layers, fluids were compelled to flow laterally along high permeability layers. Permeability changes in the carbonates we have analysed are essentially related to changes in fracture density. The lateral flow and associated cooling of chemically aggressive fluids caused widespread speleogenesis and, roughly at the same time, deposition of silica. Geometry and dimensions of cave passages are controlled by a complex interplay between the ability of flow to bring acids to the carbonate wall and retrieve the reaction products and the reaction kinetics. The direction of passage was influenced by fracture sets, but their spacing is related to intrinsic flow processes rather than to the spacing of the fractures themselves. Our model has a general value and is applicable not only to foredeep settings but also in rifted continental margin were regional flow takes place and is often intercepted by steep faults.

description: Electron spin polarizations of 32% are obtained in a GaAs quantum well via electrical injection through a reverse-biased Fe/AlGaAs Schottky contact. An analysis of the transport data using the Rowell criteria demonstrates that single step tunneling is the dominant transport mechanism. The current-voltage data show a clear zero-bias anomaly and phonon signatures corresponding to the GaAs-like and AlAs-like longitudinal-optical phonon modes of the AlGaAs barrier, providing further evidence for tunneling. These results provide experimental confirmation of several theoretical analyses indicating that tunneling enables significant spin injection from a metal into a semiconductor.

description: A non-standing character of directly imaged spin-waves in confined micron-sized ultrathin permalloy (Ni\textsubscript{80}Fe\textsubscript{20}) structures is reported along with evidence of the possibility to alter the observed state by modifications to the sample geometry. Using micromagnetic simulations the presence of the spin-wave modes excited in the permalloy stripes along with the quasi-uniform modes were calculated. The predicted spin-waves were imaged in direct space using time resolved scanning transmission X-ray microscopy, combined with a ferromagnetic resonance excitation scheme (STXM-FMR). STXM-FMR measurements revealed a non-standing character of the spin-waves. Also it was shown by micromagnetic simulations and confirmed with STXM-FMR results that the observed character of the spin-waves can be influenced by the local magnetic fields in different sample geometries.

description: We show that the definition of proper time for Weyl-invariant space-times given by Perlick naturally extends to spaces with arbitrary non-metricity. We then discuss the relation between this generalized proper time and the Ehlers-Pirani-Schild definition of time when there is arbitrary non-metricity. Then we show how this generalized proper time suffers from a second clock effect. Assuming that muons are a device to measure this proper time, we constrain the non-metricity tensor on Earth's surface and then elaborate on the feasibility of such assumption.

description: We study the behavior of several joint residence times of N independent Brownian particles in a disc of radius $R$ in two dimensions. We consider: (i) the time T_N(t) spent by all N particles simultaneously in the disc within the time interval [0,t]; (ii) the time T_N^{(m)}(t) which at least m out of N particles spend together in the disc within the time interval [0,t]; and (iii) the time {\tilde T}_N^{(m)}(t) which exactly m out of N particles spend together in the disc within the time interval [0,t]. We obtain very simple exact expressions for the expectations of these three residence times in the limit t\to\infty.

How Much and When Do We Need Higher-order Information in Hypergraphs? A Case Study on Hyperedge Prediction

description: Hypergraphs provide a natural way of representing group relations, whose complexity motivates an extensive array of prior work to adopt some form of abstraction and simplification of higher-order interactions. However, the following question has yet to be addressed: How much abstraction of group interactions is sufficient in solving a hypergraph task, and how different such results become across datasets? This question, if properly answered, provides a useful engineering guideline on how to trade off between complexity and accuracy of solving a downstream task. To this end, we propose a method of incrementally representing group interactions using a notion of n-projected graph whose accumulation contains information on up to n-way interactions, and quantify the accuracy of solving a task as n grows for various datasets. As a downstream task, we consider hyperedge prediction, an extension of link prediction, which is a canonical task for evaluating graph models. Through experiments on 15 real-world datasets, we draw the following messages: (a) Diminishing returns: small n is enough to achieve accuracy comparable with near-perfect approximations, (b) Troubleshooter: as the task becomes more challenging, larger n brings more benefit, and (c) Irreducibility: datasets whose pairwise interactions do not tell much about higher-order interactions lose much accuracy when reduced to pairwise abstractions.
Thermopower in Andreev interferometers

description: We examine the thermopower Q of a mesoscopic normal-metal (N) wire in contact to superconducting (S) segments and show that even with electron-hole symmetry, Q may become finite due to the presence of supercurrents. Moreover, we show how the dominant part of Q can be directly related to the equilibrium supercurrents in the structure. We also discuss the thermopower arising due to an anomalous kinetic coefficient which is finite in the presence of supercurrent and in some situations gives the dominant contribution. In general, a finite thermopower appears both between the N reservoirs and the superconductors, and between the N reservoirs themselves. The latter, however, strongly depends on the geometrical symmetry of the structure. The paper includes a detailed analytical derivation of the results and an exact numerical solution of the quasiclassical equations in a few sample geometries.

description: We carefully analyse the contribution to the oscillations of a metallic gravitational antenna due to the interaction between the electrons of the bar and the incoming gravitational wave. To this end, we first derive the total microscopic Hamiltonian of the wave-antenna system and then compute the contribution to the attenuation factor due to the electron-graviton interaction. As compared to the ordinary damping factor, which is due to the electron viscosity, this term turns out to be totally negligible. This result confirms that the only relevant mechanism for the interaction of a gravitational wave with a metallic antenna is its direct coupling with the bar normal modes.
