description: We extend the perturbative double copy between radiating classical sources in gauge theory and gravity to the case of spinning particles. We construct, to linear order in spins, perturbative radiating solutions to the classical Yang-Mills equations sourced by a set of interacting color charges with chromomagnetic dipole spin couplings. Using a color-to-kinematics replacement rule proposed earlier by one of the authors, these solutions map onto radiation in a theory of interacting particles coupled to massless fields that include the graviton, a scalar (dilaton) $ϕ$ and the Kalb-Ramond axion field $B_{μν}$. Consistency of the double copy imposes constraints on the parameters of the theory on both the gauge and gravity sides of the correspondence. In particular, the color charges carry a chromomagnetic interaction which, in $d=4$, corresponds to a gyromagnetic ratio equal to Dirac's value $g=2$. The color-to-kinematics map implies that on the gravity side, the bulk theory of the fields $(ϕ,g_{μν},B_{μν})$ has interactions which match those of $d$-dimensional `string gravity,' as is the case both in the BCJ double copy of pure gauge theory scattering amplitudes and the KLT relations between the tree-level $S$-matrix elements of open and closed string theory.

description: La casa editorial El Tiempo desea conocer la estratificación socioeconómica de sus clientes del segmento impreso en Bogotá, partiendo solo de las direcciones, para esto se hizo la exploración y tratamiento de la EMB21, como insumo para determinar el ingreso promedio de los habitantes de la zona urbana; el proceso comprende: el manejo de faltantes, la normalización por logaritmo natural, el trabajo con muestreo estratificado usando factor de expansión, el tratamiento de los datos atípicos y el manejo de expresiones regulares; dando como resultado una tabla de ingresos por estrato (1 al 6) y UPZ para Bogotá. Luego, se hicieron cruces geoespaciales de las UPZ y las manzanas estratificadas, para obtener la cartografía de Bogotá en estratos residenciales, que luego de integrarse con la salida anterior proporcionan información estimada de ingresos para cada una de las manzanas de Bogotá. Haciendo uso de estos datos se desarrolló en Python una herramienta analítica, que georreferencia las direcciones ingresadas, mediante el API de ArcGIS y devuelve para cada una de las direcciones la geolocalización, junto con información enriquecida de la EMB21, brindando así un poderoso instrumento para estimar ingresos, segmentar clientes, ofrecer campañas dirigidas, tomar decisiones basadas en datos, entre otros usos.
description: La casa editorial El Tiempo wants to know the socioeconomic stratification of its clients in the printed segment in Bogota, having just the addresses, for this, the exploration and treatment of the EMB21 was made, as an input to determine the average income of the urban area population; the process includes: missing data handling, normalization by natural logarithm, stratified sampling work using the expansion factor, atypical data and regular expressions treatment; resulting in an income table by social strata (1 to 6) and UPZ for Bogotá. Next, UPZ geospatial crosses and social strata blocks were used to obtain Bogota's cartography by residential social strata, which after integrating with the previous output, provide estimated income information for each of Bogota's blocks. Using these data, an analytical tool was developed in Python, which receives a series of addresses from Bogota, georeferencing them using ArcGIS API and returns the geolocation for each of the addresses, in combination with enriched information from the EMB21, as a result, a powerful tool was provided to estimate incomes, segment customers, offer targeted campaigns, make decisions based on data, among other uses.

description: In some applications there arises the need of a spatially distributed description of a physical quantity inside a device coupled to a circuit. Then, the in-space discretised system of partial differential equations is coupled to the system of equations describing the circuit (Modified Nodal Analysis) which yields a system of Differential Algebraic Equations (DAEs). This paper deals with the differential index analysis of such coupled systems. For that, a new generalised inductance-like element is defined. The index of the DAEs obtained from a circuit containing such an element is then related to the topological characteristics of the circuit's underlying graph. Field/circuit coupling is performed when circuits are simulated containing elements described by Maxwell's equations. The index of such systems with two different types of magnetoquasistatic formulations (A* and T-$Ω$) is then deduced by showing that the spatial discretisations in both cases lead to an inductance-like element.

description: To get insights into the functions of metallothionein (MT) in plant response to multiple stresses, expressions of 10 rice MT genes (OsMTs) and 7 Arabidopsis MT genes (AtMTs) were comprehensively analyzed under combined heavy metal and salt stress. OsMT1a, OsMT1b, OsMT1c, OsMT1g, and OsMT2a were increased by different heavy metals. Notably, ABA remarkably increased OsMT4 up to 80-fold. Combined salt and heavy metals (Cd, Pb, Cu) synergistically increased OsMT1a, OsMT1c, and OsMT1g, whereas combined salt and H2O2 or ABA synergistically increased OsMT1a and OsMT4. Heavy metals decreased AtMT1c, AtMT2b, and AtMT3 but cold or ABA increased AtMT1a, AtMT1c, and AtMT2a. AtMT4a was markedly increased by salt stress. Combined salt and other stresses (Pb, Cd, H2O2) synergistically increased AtMT4a. Taken together, these findings suggest that MTs in monocot and dicot respond differently to combined stresses, which provides a valuable basis to further determine the roles of MTs in broad stress tolerance. MTs in monocot and dicot respond differently to single stress or combined salt and heavy metal, which provides information to generate plants with broad stress tolerance.

description: This paper investigates the impact monetary policy shocks have on housing markets in Canada using both national and city level data. The data which includes spans the period of 1999-2016 includes house prices, housing starts and residential investment as housing market variables. This study uses a structural VAR model and a Bayesian process to generate impulse response functions for the national economy. National level monetary policy shocks identified through this process are used in projection method estimate the impact on regional housing markets of Vancouver, Calgary, Winnipeg, Toronto, Ottawa, Montreal and Halifax. The results suggest that house prices in Calgary may respond to monetary policy shocks but beyond this finding, the results fail to identify any prominent national or regional responses to monetary policy shocks.
Do temperature surprise shocks in urban Canada lead to inflationary pressures?

description: As the consequences of changing temperatures unfold with increasing severity in Canada, understanding the impact of climate change is critical. So far, no consensus has been reached on the magnitude or direction of the effects of temperature shocks. Using monthly data at the census metropolitan area (CMA) level, I create a novel Canadian shock series of the weighted average surprise of extreme temperature realizations in each quarter. I isolate the unexpected component of these weather events by controlling for the adjustments of expectations over time. My empirical analysis provides evidence that adverse temperature shocks lead to mostly deflationary pressures on the Canadian economy. These pressures are persistent, and primarily driven by cold shocks.

description: The design and optimization of the Electromagnetic Calorimeter (ECAL) are crucial for the Circular Electron Positron Collider (CEPC) project, a proposed future Higgs/Z factory. Following the reference design of the International Large Detector (ILD), a set of silicon-tungsten sampling ECAL geometries are implemented into the Geant4 simulation, whose performance is then scanned using Arbor algorithm. At single particle level, the photon energy response at different ECAL longitudinal structures is analyzed. At bi-particle sample, the separation performance with different ECAL transverse cell sizes is investigated and parametrized. The overall performance is characterized by a set of physics benchmarks, including $ννH$ events where Higgs boson decays into a pair of photons (EM objects) or gluons (jets) and $Z\toτ^+τ^-$ events. Based on these results, we proposed an optimized ECAL geometry for the CEPC project.

description: Over the last decades, bilateral trade agreements (BTAs) have increased considerably in number and economic relevance. Notably, such agreements substantially affect global trade, since the reorganization of flows of goods and services has prominent impacts on the contracting countries' economies, but also on other parties that are (directly or indirectly) engaged in trade with these countries. Here, we empirically study the effect of BTAs on the input-output linkages between the contractual parties' national economic sectors by defining a new measure of Trade Interconnectedness (TI), which describes the relative importance of direct and indirect production linkages between the two countries in the international trade network. By analyzing its time evolution for each pair of trade agreement partners, we demonstrate that while most BTAs are succeeded by an increase in TI between the contractors, there are some notable exceptions. In particular, comparing the trade profiles of China and the United States (US), we find indications that both countries have been pursuing fundamentally different objectives and strategies related to the negotiation of BTAs.

description: The efficacy of STING (stimulator of interferon genes) agonists is due to various factors, primarily inefficient intracellular delivery, low/lack of endogenous STING expression in many tumours, and a complex balance between tumour control and progression. Here we report a universal STING mimic (uniSTING) based on a polymeric architecture. UniSTING activates STING signalling in a range of mouse and human cell types, independent of endogenous STING expression, and selectively stimulates tumour control IRF3/IFN-I pathways, but not tumour progression NF-κB pathways. Intratumoural or systemic injection of uniSTING-mRNA via lipid nanoparticles (LNPs) results in potent antitumour efficacy across established and advanced metastatic tumour models, including triple-negative breast cancer, lung cancer, melanoma and orthotopic/metastatic liver malignancies. Furthermore, uniSTING displays an effective antitumour response superior to 2′3′-cGAMP and ADU-S100. By favouring IRF3/IFN-I activity over the proinflammatory NF-κB signalling pathway, uniSTING promotes dendritic cell maturation and antigen-specific CD8+ T-cell responses. Extracellular vesicles released from uniSTING-treated tumour cells further sensitize dendritic cells via exosome-containing miRNAs that reduced the immunosuppressive Wnt2b, and a combination of LNP-uniSTING-mRNA with α-Wnt2b antibodies synergistically inhibits tumour growth and prolongs animal survival. Collectively, these results demonstrate the LNP-mediated delivery of uniSTING-mRNA as a strategy to overcome the current STING therapeutic barriers, particularly for the treatment of multiple cancer types in which STING is downregulated or absent.

description: Purpose: Previous investigations revealed influences of irradiation up to 2.0 Gy on the cytokine secretion profile of inflammatory, peritoneal mouse macrophages (pMФ). This raised the question if those alterations impact on dendritic cells and consecutive T-cell responses. Further, the impact of irradiation directly on pMФ capacity to induce T-cell responses was analyzed. Materials and Methods: pMФ were LPS-activated, irradiated and the expression of activation markers was assessed. Treated pMФ were co-incubated with T-cells to investigate proliferation. To verify modulating properties of pMФ supernatants isolated 24 h after irradiation, bone marrow-derived dendritic cells (BMDC) were co-incubated with supernatants and activation markers as well as the BMDC-induced proliferation of T-cells were measured. Results: pMФ showed a highly significantly decreased MHCII expression within a dose range from 0.7 to 2.0 Gy. Further, the proliferation rate of CD4+ T-cells was decreased after co-incubation with in particular 2.0 Gy irradiated pMФ. The co-incubation of BMDC with supernatants of activated, irradiated pMФ significantly reduced the CD40 expression, but did not impact on the BMDC-derived induction of T-cell proliferation. Conclusions: Inflammatory macrophages being exposed to irradiation have the potential to modulate consecutive adaptive immune reactions. But supernatants of irradiated macrophages do not influence the DC-mediated induction of T cell proliferation.

Markers of Economic Modernization and the Overexploitation of Fish Stocks
Creators: name: Zanette, Eric
Publisher: name: My University
Year: 2020

description: This paper investigates how the levels of trade openness, credit market access and the strength of property rights affect the level of overfishing within a state’s Exclusive Economic Zone. A comparison is made between Erhardt (2018), who explores how overfishing is affected by trade openness and strength of property rights, and Noack and Costello (2019), who explore how overfishing is affected by access to credit markets and the strength of property rights. We use a dynamic linear fixed effect model and by including all relevant variables we test both papers for omitted variable bias. We find that the individual effects of increased property rights and access to credit markets decreases and increases levels of overfishing respectively while trade openness had no effect. This points to a degree of omitted variable bias in Erhardt’s results as he concludes that increased trade openness decreases overfishing. The interaction terms of these variables are further explored through the use of marginal analysis.

description: Este artículo analiza los criterios para el reconocimiento del desplazamiento forzado por proyectos de desarrollo minero en comunidades étnicas y su relación con la reparación integral. En la normatividad colombiana existe un vacío frente a esta problemática. Dicha falta de reconocimiento lleva a que figuras como la reubicación, implementada para mitigar los daños causados por los proyectos de desarrollo, no resulte efectiva, ni suficiente, para la protección de la población vulnerada. El presente análisis se realizará a partir del estudio de caso de las comunidades negras afectadas por la explotación de la mina El Cerrejón, con base en dos sentencias de la Corte Constitucional, en las cuales se estudia el impacto de los procesos de reasentamiento de estas comunidades. Por último, se examinará cómo la reparación integral puede ser una garantía aplicable para los procesos donde se configura el desplazamiento forzado inducido por proyectos de desarrollo minero.
description: This article aims to analyze the criteria for the recognition of forced displaced population by mining projects in ethnic population and its relation with integral reparation. There is a legal gap in Colombia regarding this problem. The lack of recognition means that figures such as relocation, implemented to mitigate the damages caused by development projects, are not effective and inadequate for the protection of population. This analysis is based on a study case of the black communities affected by the exploitation of the Cerrejón mine, based on two decisions of the Constitucional Court, where the impact of the resettlement processes of these communities has been studied. Finally, the article will examine how integral reparation could be a guarantee for forced displaced population induced by development projects.

Legalization of Recreational Marijuana in Canada: Implications from Provinces’ Price Difference
Creators: name: Bouga Ela, Michelle
Publisher: name: My University
Year: 2018

description: Due to the positive and negative returns that may come with marijuana legalization, it is of prime importance to assess the interdependence that might be generated at the provincial level. Specifically, how can the provincial price difference affect the level of consumption and violent criminal code violations within each province and in neighboring regions. So, investigating whether there is a spatial dependence that might generate spillover effects will reveal how can a province and/or its neighbors benefits from the price difference or to which extend it can be prejudicial. I analyzed the effect of variations in price of medical and non-medical marijuana in thirteen Canadian provinces including territories from 2011 to 2016 using panel data with 65 observations. The results although sensitive to alternative specifications and models, showed a constant pattern. On one hand, an increase in the price of medical marijuana increases the demand for non-medical marijuana in neighboring areas whereas, an increase in the price of non-medical marijuana reduces its demand in neighboring provinces. Thus, the variable non-medical cannabis does not exhibit the expected bootlegging behavior. On the other hand, the variation in one element of justice namely total violent criminal code violations is very sensitive to the functional form of the variables. While the logarithmic specification did not capture any spatial dependence in the variables, the percentage change modelling showed that an increase in the price of medical marijuana in one region leads to an increase in the total transgressions in neighboring regions whereas, an increase in the price of non-medical marijuana in one area decreases the number of violent criminal code violations in neighboring areas. These results on quantity demanded of non-medical marijuana and total violent criminal code violations complement each other.

We develop a multi-binned sensitivity measure and use it to estimate the sensitivity for the entire range of $N$ masses, spanning the standard and merged prompt signals, displaced vertices and the invisible $N$ region. The estimated sensitivity of the LHC with 300/fb integrated luminosity ranges from 5 to beyond 7 TeV, while the future 33(100) TeV collider's reach with 3/ab extends to 12(26) TeV.

description: This research aimed at evaluating the safety, and the type, level and prevalence of mycotoxins in grain sorghum of four sub-Saharan African (SSA) countries (Burkina Faso, Ethiopia, Mali and Sudan). A multi-analyte LC-MS/MS method for quantification of 23 mycotoxins (nivalenol, deoxynivalenol, fusarenon X, neosolaniol, 3-acetyl deoxynivalenol, 15-acetyl deoxynivalenol, diacetoxyscirpenol, roquefortine C, HT-2 toxin, alternariol, T-2 toxin, FB1, FB2, FB3, zearalenone, aflatoxin G1, aflatoxin G2, aflatoxin B1, aflatoxin B2, sterigmatocystin, OTA, altenuene, alternariol monomethylether) was applied to different sorghum matrices. Of the 1533 analysed samples, 33% were contaminated with at least one of the following mycotoxins: aflatoxins, fumonisins, sterigmatocystin, Alternaria toxins, OTA and zearalenone. Country of origin, colour, source and collection period of sorghum samples significantly influenced the type, level and prevalence of mycotoxins. Sterigmatocystin (15%), fumonisins (17%) and aflatoxins (13%) were the most prevalent. FB1 (274 ± 585 µg/kg) had the highest mean concentration followed by FB2 (214 ± 308 µg/kg) while diacetoxyscirpenol (8.12 ± 19.2 µg/kg) and HT-2 (11.9 ± 0.00 µg/kg) had the lowest concentrations. Neosolaniol, fusarenon-X, 3-acetyl deoxynivalenol, 15-acetyl deoxynivalenol, T-2 toxin, nivalenol and roquefortine C were not detected in any of the samples. Sudan had the lowest prevalence and mean concentration of all mycotoxins. Pink sorghum had the highest concentrations of fumonisins and aflatoxins. Mycotoxins from Aspergillus spp. and Alternaria spp. are the mycotoxins of concern in SSA grain sorghum with regard to prevalence, concentration and possible health risk from exposure. Based on the performed risk characterisation, daily consumption of sorghum containing aflatoxins, alternariol, alternariol monomethyl ether, sterigmatocystin and OTA could result in exceeding the established health-based guidance values for these toxins.

description: Quantum walks with long-range steps $R^{-γ}$ ($R$ being the distance between sites) on a discrete line behave in similar ways for all $γ\geq2$. This is in contrast to classical random walks, which for $γ>3$ belong to a different universality class than for $γ\leq 3$. We show that the average probabilities to be at the initial site after time $t$ as well as the mean square displacements are of the same functional form for quantum walks with $γ=2$, 4, and with nearest neighbor steps. We interpolate this result to arbitrary $γ\geq2$.

description: The present day spectrum of the extragalactic background light (EBL) in UV, optical and IR wavelengths is the integral result of multiple astrophysical processes going on throughout the evolution of the Universe. The relevant processes include star formation, stellar evolution, light absorption and emission by the cosmic dust. The properties of these processes are known with uncertainties which contribute to the EBL spectrum precision. In the present paper we develop a numerical model of the EBL spectrum while maintaining the explicit dependence on the astrophysical parameters involved. We constructed a Markov Chain in the parameter space by using the likelihood function built with the up-to-date upper and lower bounds on the EBL intensity. The posterior distributions built with the Markov Chain Monte Carlo method are used to determine an allowed range of the individual parameters of the model. Consequently, the star formation rate multiplication factor is constrained in the range $1.01 < C_{\mbox{sfr}} < 1.69$ at $68\%$ C.L. The method also results in the bounds on the lifetime, radius, dust particle density and opacity of the molecular clouds that have large ambiguity otherwise. It is shown that there is a reasonable agreement between the model and the intensity bounds while the astrophysical parameters of the best fit model are close to their estimates from literature.

The Arts and Culture Sector in Major Canadian Census Metropolitan Areas: Is its Workforce as Diverse as the Population it Serves?
Creators: name: Nguyen, Anh Thi
Publisher: name: My University
Year: 2018

description: This research paper studies the workforce diversity in the arts and culture sector in the four largest Canadian Census Metropolitan Areas (CMAs) in 2011, namely Toronto, Vancouver, Montreal, and Ottawa-Gatineau. It uses the National Household Survey (NHS) 2011 to examine the degree to which cultural occupations are inclusive of females, immigrants, visible minorities, and Aboriginals. The analysis shows that the cultural labour force in all four CMAs is not as diverse as the population it serves and all of these four designated groups are poorly remunerated compared to their counterparts. Although all levels of government have adopted many initiatives to respond to this situation, the literature shows that many issues still exist in the current cultural funding policies and cultural planning. Based on the findings of this study, a set of recommendations is proposed in order to equip policymakers to act and to improve the situation. Lastly, the paper emphasizes that diversity does not automatically transfer into success. Managing diversity - how we value and promote diversity - is key to enjoying its invaluable benefits. However, increasing representation of these disadvantaged groups is the first important step, which is a prerequisite for any further improvement.

description: Parity games have important practical applications in formal verification and synthesis, especially to solve the model-checking problem of the modal mu-calculus. They are also interesting from the theory perspective, as they are widely believed to admit a polynomial solution, but so far no such algorithm is known. In recent years, a number of new algorithms and improvements to existing algorithms have been proposed. We implement a new and easy to extend tool Oink, which is a high-performance implementation of modern parity game algorithms. We further present a comprehensive empirical evaluation of modern parity game algorithms and solvers, both on real world benchmarks and randomly generated games. Our experiments show that our new tool Oink outperforms the current state-of-the-art.

description: In the framework of WZW-like open superstring field theory (SSFT) including the Ramond (R) sector whose action was constructed by Kunitomo and Okawa, we truncate the string fields in both the Neveu-Schwarz (NS) and R sectors up to the lowest massless level and obtain the ten-dimensional super Yang-Mills (SYM) action with bosonic extra term by explicit calculation of the SSFT action. Furthermore, we compute a contribution from the massive part up to the lowest order and find that the bosonic extra term is canceled and instead a fermionic extra term appears, which can be interpreted as a string correction to the SYM action. This calculation is an extension to the R sector of the earlier work by Berkovits and Schnabl in the NS sector. We also study gauge transformation, equation of motion, and spacetime supersymmetry transformation of the massless component fields induced from those of string fields.

description: Mediante un trabajo de campo etnográfico de observador participante realizado en el municipio de Boyacá, interactuando con los propios protagonistas el autor se aproxima a la fiesta y devoción de San Isidro Labrador en el municipio de Boyacá en el departamento de Boyacá Colombia. El culto al santo y la expectativa de que él pueda intervenir en las lluvias y el sol para fertilizar los campos y tener buenos frutos es sólo un aspecto. ¿Sirve el culto para pacificar la lucha de clases entre el campesino jornalero desposeído y los patrones dueños de la tierra y de los medios de producción? El campesino asume una deuda con Dios, con la naturaleza, con el Santo patrón de los labriegos y la agricultura, la bondad de Dios, del santo, del patrón genera una acreencia que nunca podrá pagar. El estudio de la economía campesina por parte de la antropología, para el caso de Colombia, se abre como un campo promisorio para la investigación dadas las diferencias en el desarrollo desigual en las regiones y la convivencia no siempre pacífica de diferentes grupos étnicos y socioeconómicos en disputa del territorio y sus recursos.
description: Through an ethnographic fieldwork of participating observer carried out in the municipality of Boyacá, interacting with the protagonists themselves, the author approaches the festival and devotion of San Isidro Labrador in the municipality of Boyacá in the department of Boyacá Colombia. The cult of the saint and the expectation that he can intervene in the rains and the sun to fertilize the fields and have good fruits is only one aspect. Does worship serve to pacify the class struggle between the dispossessed peasant laborer and the bosses who own the land and the means of production? The peasant assumes a debt with God, with nature, with the patron saint of farmers and agriculture, the goodness of God, of the saint, of the patron generates an accretion that he can never pay. The study of peasant economics by anthropology, in the case of Colombia, opens up as a promising field for research given the differences in unequal development in the regions and the not always peaceful coexistence of different ethnic and socioeconomic groups in dispute of the territory and its resources.
Isotropic-Nematic Phase Transitions in Gravitational Systems II: Higher Order Multipoles

description: The gravitational interaction among bodies orbiting in a spherical potential leads to the rapid relaxation of the orbital planes' distribution, a process called vector resonant relaxation. We examine the statistical equilibrium of this process for a system of bodies with similar semimajor axes and eccentricities. We extend the previous model of Roupas et al. (2017) by accounting for the multipole moments beyond the quadrupole, which dominate the interaction for radially overlapping orbits. Nevertheless, we find no qualitative differences between the behavior of the system with respect to the model restricted to the quadrupole interaction. The equilibrium distribution resembles a counterrotating disk at low temperature and a spherical structure at high temperature. The system exhibits a first order phase transition between the disk and the spherical phase in the canonical ensemble if the total angular momentum is below a critical value. We find that the phase transition erases the high order multipoles, i.e. small-scale structure in angular momentum space, most efficiently. The system admits a maximum entropy and a maximum energy, which lead to the existence of negative temperature equilibria.

Multi-Variate EEG Analysis as a Novel Tool to Examine Brain Responses to Naturalistic Music Stimuli

description: Note onsets in music are acoustic landmarks providing auditory cues that underlie the perception of more complex phenomena such as beat, rhythm, and meter. For naturalistic ongoing sounds a detailed view on the neural representation of onset structure is hard to obtain, since, typically, stimulus-related EEG signatures are derived by averaging a high number of identical stimulus presentations. Here, we propose a novel multivariate regression-based method extracting onset-related brain responses from the ongoing EEG. We analyse EEG recordings of nine subjects who passively listened to stimuli from various sound categories encompassing simple tone sequences, full-length romantic piano pieces and natural (non-music) soundscapes. The regression approach reduces the 61-channel EEG to one time course optimally reflecting note onsets. The neural signatures derived by this procedure indeed resemble canonical onset-related ERPs, such as the N1-P2 complex. This EEG projection was then utilized to determine the Cortico-Acoustic Correlation (CACor), a measure of synchronization between EEG signal and stimulus. We demonstrate that a significant CACor (i) can be detected in an individual listener's EEG of a single presentation of a full-length complex naturalistic music stimulus, and (ii) it co-varies with the stimuli’s average magnitudes of sharpness, spectral centroid, and rhythmic complexity. In particular, the subset of stimuli eliciting a strong CACor also produces strongly coordinated tension ratings obtained from an independent listener group in a separate behavioral experiment. Thus musical features that lead to a marked physiological reflection of tone onsets also contribute to perceived tension in music.

description: Si no me falla la memoria, conocí a Manuel Aragón en junio de 1984. Acababa de regresar a España tras una estancia de nueve meses en Roma, donde recalé gracias a una beca para ampliar estudios en el Instituto Jurídico Español que tenía su sede en la capital italiana. Mi intención era incorporarme como profesor contratado al seminario de Derecho Político de la Facultad de Valladolid, en la que me había licenciado dos años antes. Paloma Biglino, que ya impartía docencia como profesora de Derecho Constitucional en esas fechas, me sugirió que concertase una entrevista con Manuel Aragón, quien ocupaba desde 1981 la cátedra en la Universidad de Valladolid y era al mismo tiempo director del Centro de Estudios Constitucionales.
Undergraduate Ancillaries in the Economics Department at the University of North Carolina at Chapel Hill

description: The Economics Department at the University of North Carolina at Chapel Hill (UNC) has had a long-term commitment to offering extra-curricular opportunities for undergraduate students to enhance their learning beyond the classroom. These opportunities include research, problem-solving, leadership development, Undergraduate Learning Assistance (ULA), peer tutoring, and networking events, among others. Given the Economics program’s substantial size within UNC’s College of Arts and Sciences—with over 1400 declared or intended majors in recent years—it is important to structure the activities in a manner that accommodates students’ diverse interests as well as their time constraints. In this paper, we introduce these different activities and discuss their scope, skill objectives, and time commitment. The benefits to students include opportunities for community, networking, exposure, application, teamwork, presentation, analysis, and research. We also discuss several challenges a department faces to successfully offer these diverse opportunities.
Rotational and fine structure of open-shell molecules in nearly degenerate electronic states

description: An effective Hamiltonian without symmetry restriction has been developed to model the rotational and fine structure of two nearly degenerate electronic states of an open-shell molecule. In addition to the rotational Hamiltonian for an asymmetric top, this spectroscopic model includes energy separation between the two states due to difference potential and zero-point energy difference, as well as the spin-orbit (SO), Coriolis, and electron spin-molecular rotation (SR) interactions. Hamiltonian matrices are computed using orbitally and fully symmetrized case (a) and case (b) basis sets. Intensity formulae and selection rules for rotational transitions between a pair of nearly degenerate states and a nondegenerate state have also been derived using all four basis sets. It is demonstrated using real examples of free radicals that the fine structure of a single electronic state can be simulated with either a SR tensor or a combination of SO and Coriolis constants. The related molecular constants can be determined precisely only when all interacting levels are simulated simultaneously. The present study suggests that analysis of rotational and fine structure can provide quantitative insights into vibronic interactions and related effects.
