description: We investigate how the coherent spreading of the center of mass wave function of a particle, such as an atom, molecule or ion, affects the particle's interaction with fields such as the electromagnetic field or a phonon field, in view also of possible applications to emerging quantum technologies. To this end, we develop a suitably generalized Unruh-deWitt model for the interaction between a delocalizing first quantized particle and a second quantized field. We study how the coherent spreading of the center of mass wave function of the particle affects emission and absorption rates and we find, in particular, that in the case of a supersonic coherent spreading in a medium, there should occur Cherenkov-like emissions, along with the excitation of the particle.

description: In this study, we report a facile method to prepare magnetic zeolitic imidazolate framework-7@graphene oxide (mag-ZIF-7@GO) composites with the assistance of polydopamine. Moreover, their potential for extracting fungicides from environmental water and soil samples is evaluated. Combining ZIF units and GO layers synergistically enhances the preconcentration of fungicides. A sensitive magnetic solid-phase extraction method based on mag-ZIF-7@GO coupled to LC-MS is developed to determine seven fungicides (pyrimethanil, triadimenol, flutriafol, tebuconazole, hexaconazole, diniconazole and bitertanol) as a function of optimised salt concentration, pH, extraction time, and desorption time. Under optimal conditions, the method exhibits good linearity, repeatability, and reproducibility. The limits of detection and limits of quantification for the seven fungicides are 0.58–2.38 ng/L and 1.95–7.94 ng/L, respectively. Furthermore, the proposed method is applied to determine trace fungicides in environmental water and soil samples, with recoveries of 81.8–96.7%, 87.2–96.3%, and 82.4–93.4% for pond water, river water, and soil, respectively. Therefore, this method has great potential for trace analysis of pollutants in complex environmental matrices.
Resistance Noise Near to Electrical Breakdown: Steady State of Random Networks as a Function of the Bias

description: A short review is presented of a recently developed computational approach which allows the study of the resistance noise over the full range of bias values, from the linear regime up to electrical breakdown. Resistance noise is described in terms of two competing processes in a random resistor network. The two processes are thermally activated and driven by an electrical bias. In the linear regime, a scaling relation has been found between the relative variance of resistance fluctuations and the average resistance. The value of the critical exponent is significantly higher than that associated with 1/f noise. In the nonlinear regime, occurring when the bias overcomes the threshold value, the relative variance of resistance fluctuations scales with the bias. Two regions can be identified in this regime: a moderate bias region and a pre-breakdown one. In the first region, the scaling exponent has been found independent of the values of the model parameters and of the bias conditions. A strong nonlinearity emerges in the pre-breakdown region which is also characterized by non-Gaussian noise. The results compare well with measurements of electrical breakdown in composites and with electromigration experiments in metallic lines.

description: Funding agencies increasingly require detailed plans for data management, sharing, and archiving during the grant submission process. Researchers may lack the knowledge required to design and implement a feasible plan for long term storage and secondary analysis of their data, such as technical specifications, metadata standards, and archival challenges pertinent to the types of data they will collect. Librarians, information specialists, and grants compliance administrators in university settings are the natural partners of these researchers; however, these partners may also lack the necessary expertise in managing the data lifecycle. This paper will report the extent to which programs in schools of library and information science (LIS) are formally preparing students for positions in data curation and data librarianship. The results of a content analysis (currently in progress) of North American LIS program websites (iSchools caucus members and American Library Association-accredited programs) will be presented. This presentation will offer a comprehensive snapshot of the courses, certifications, tracks of study, centers/institutes, and grant-funded initiatives that are currently available to those who wish to work in data curation, in the hopes of initiating a conversation about the skills and knowledge needed by data professionals and how LIS programs can help to prepare them.

description: Arresting the decline of mangrove forests and mainstreaming people‟s participation in their management provided the rationale for community-based mangrove rehabilitation in the Philippines. Mangrove rehabilitation aims to re-establish habitat and functions that have been lost. In the context of coastal resource management, the risk that typhoons could alter socioeconomic and institutional goals of communitybased mangrove rehabilitation and the dearth of information on impacts of typhoon on such goals and combined income-asset shocks on households presents a great challenge. This paper analyzed the economic effects of typhoon and its impact on community-based mangrove rehabilitation community in the coastal municipality of Malinao, southeastern Luzon. Key informant interview, household and mangrove transect surveys were used in data gathering. Valuation of damaged crops and lost assets were used in quantifying direct economic effects. A time-one, time-two comparison technique was used in quantifying impacts. The results showed the direct damage on crops was highest in rice. The damage on physical assets was highest in fishing gears. The damage on livestock was highest in small animals. The cost of repair was highest for concrete houses, although native houses had the highest proportion of damage. Total direct damage cost valued at PhP 24.33 million justifies public investment in disaster risk management. Per capita damage cost at PhP 12,581 equivalent to 3-month household income shortfall can derail early recovery. The indirect social impacts increased access on social services as window of opportunities brought by the disaster event but are ad hoc in nature. The old mangrove forest population was very slightly impacted but the reforested mangrove was dramatically reduced. Most of the institutional performances in resource management and livelihood sustainability plans were negatively impacted. Livelihood projects with live production assets were more vulnerable and incurred heavy losses from typhoon. The typhoon resulted to very minimal gains on overall natural resource management goals posting slight positive changes on stakeholders influence on mangrove resource management, control over resources, collective decision-making, and knowledge. Coping mechanisms and implications for disaster mitigation and sustainable management were discussed.

description: El objetivo de este trabajo fue, en primer lugar, analizar la evolución de la competitividad del sector arrocero, medido a través del volumen de recursos financieros que transfiere hacia otros sectores de la economía En segundo lugar, se procuró estimar el resultado económico resultante de un paquete tecnológico a ser aplicado en un marco de intensificación de la producción, co:nsiderando la sostenibilidad ambiental del cultivo. No obstante su muy alta capacidad competitiva, la cadena arrocera no es neutral a los efectos de las políticas públicas. En los últimos años se viene observando un importante deterioro en la competitividad del sector. Los costos de producción han venido sufriendo un importante incremento, fundamentalmente los no transables (salarios y cargas sociales). afectando no solo la rentabilidad del negocio sino también su capacidad contributiva a la economía nacional. Para que el sector cumpla con la cuota de aporte que le requiere la sociedad. la rentabilidad del negocio debe ser una condición necesaria ya que su competitividad no es infinita. El sector debe poder seguir creciendo en forma sostenible, desde el punto de vista económico, social y ambiental. La investigación ha venido mostrando que aun con la tecnología actual se puede intensificar la producción y mejorar la ecuación económica, mejorando incluso el desempeño de los principales indicadores ambientales. Los resultados de este estudio sugieren que una mejora en la combinación de insumas y prácticas de manejo a nivel de chacra puede marcar la diferencia entre obtener un resultado positivo o negativo.

description: El Instituto Nacional de Investigación Agropecuaria (INIA), los molinos integrantes de la Gremial de Molinos Arroceros (GMA) y la empresa Coopar S.A., y la Asociación de Cultivadores de Arroz (ACA), vienen ejecutando en conjunto, desde 2013, el proyecto "Rompiendo el techo de rendimiento del cultivo de arroz'' (ANII ALI_1_2012_1_3507). El objetivo general del mismo es generar tecnologías y prácticas de manejo integrado del cultivo que permitan incrementar al menos 10% la productividad, respecto a la obtenida con la tecnología actualmente utilizada por los productores pertenecientes al quintil superior de rendimiento. Uno de los objetivos específicos (OE N°3) del proyecto plantea la generación de una propuesta económicamente viable de manejo integrado del cultivo de arroz para aumentar la productividad respecto a la obtenida por los productores del quintil superior. El objetivo del presente trabajo apunta en ese sentido. Como reza su título, intenta ponerle los primeros números a las propuestas tecnológicas que surgen del referido proyecto. Debido a las restricciones de tiempo del proyecto RTR los trabajos de validación se realizaron solamente para una zafra (2016/17). Esto implica que las conclusiones deben tomarse con la precaución debida. De todos modos, surgen elementos que ameritan ser destacados. Los resultados obtenidos parecen confirmar que una profunda revisión en la estructura de costos a nivel de chacra puede ser la diferencia entre obtener un resultado económico y financiero positivo o negativo. Es posible seguir trabajando en procura de lograr una mejor combinación en el uso de los insumos. A partir de la tecnología disponible, aún es posible lograr ajustes que permitan romper los techos actuales de rendimiento.

description: The increase and profusion of flavors of data librarianship, in the forms of service, management, curation and visualization have left many of the current data librarians wondering: what's the difference? Did the name of the profession get coopted to something brand new? Or are these "new breed" data librarians remixing or rebranding skills that social science data librarians have acquired through time? Or does the proliferation and change of descriptions actually signal a maturation of the profession? In this paper we will analyze position descriptions from job ads for data-related positions (largely in the US Canada) from the last 4 years, present some in-depth case studies of data librarians in various forms, map the positions in their organizational contexts, and submit some suggestions for future job description language and content to the IASSIST audience for scrutiny and reflection.

description: The direct detection of particle dark matter through its scattering with nucleons is of fundamental importance to understand the nature of DM. In this work, we propose that the high-energy neutrino detectors like IceCube can be used to uniquely probe the DM-nucleon cross-section for high-energy DM of $\sim$ PeV, up-scattered by the high-energy cosmic rays. We derive for the first time strong constraints on the DM-nucleon cross-section down to $\sim 10^{-32}$ cm$^2$ at this energy scale for sub-GeV DM candidates. Such independent probe at energy scale far exceeding other existing direct detection experiments can therefore provide useful insights complementary to other searches.

description: A novel colorimetric probe based on the bromopyrogallol red (BPR) for the sequential detection of Bi3+ and C2O42− was designed. The presence of Bi3+ led to a distinct naked-eye colour change in DMSO/H2O (1:3, v/v) media. The detection limit of BPR for Bi3+ was down to nanomolar concentration (1.17 nmol L−1). Also, the sensing ability of BPR for Bi3+ was successfully carried out in bismuth tablet and urine sample. Moreover, the resulting BPR-Bi3+ complex acted as an efficient colorimetric chemosensor for C2O42− via a colour change. Therefore, chemosensor BPR-Bi3+ can illustrate the ability to determine C2O42- up to 0.15 µmol L−1, selectively. Notably, the absorbance changes of BPR upon the addition of Bi3+ and C2O42− were utilised as AND and NAND logic gates operating at the molecular level with Bi3+and C2O42− as chemical inputs and the absorbance signal as the output. The chemical inputs of Bi3+ and C2O42- in a sequential system produce an output which mimics the operation of a security keypad lock. This study provides a practical application for the sensing of C2O42− ions in vegetable and urine samples by the construction of the supramolecular system.
Subtle Sensations : Restoration Within A Vibrational Boundary

description: The unseen world connects humans to the cosmos and the earth. The invisible forces that exist around us have the capability to affect our physical, visible and energetic, unseen bodies. Because of synthetic frequencies emitting from the obscene number of contemporary technologies, an individual’s energetic body becomes scrambled. The body then has difficulties to self-regulate and maintain healthy functions, resulting in depression, insomnia, and diseases that manifest themselves physically. Therefore, Subtle Sensations encourages people to remove themselves from harmful short and fast synthetic frequencies found primarily in urban settings and bond with the beneficial long and slow frequencies of vegetation, fungi, and crystals by collecting their voices through bio-sonification and then experiencing their cymatic patterns. This in turn allows individuals to communicate with other Beings while becoming more aligned with the Schumann Resonance: Earth’s natural frequency that many people have seemingly become out of synch with. Utilizing principles of reiki, Subtle Sensations proposes a Frequency Theatre that will inspire an architecture that promotes a healthier metaphysical body of an individual and strengthens an individual’s connection to the seen-and-unseen earth.

Year: 2012

description: The landscape of research, resources, involved organizations, and services related to social science data has developed quite differently in the USA and in Germany in the last few decades. For instance, while established (even if still developing) in the USA, the role of a designated "data librarian" in the academic/research environment is something quite new in Germany; while the federal statistical system in the USA is based on the activities of several dozen individual agencies, Germany has a single Federal Statistical Office, along with at least equally important central statistical offices for each of its states; and the practice of conducting a nationwide census of the population is established and largely unchallenged in the USA, but was so controversial in (West) Germany in the 1980s that it would not be undertaken again until 2011. Meanwhile, the ideas and challenges of sharing research data, planning for its management, providing curation services and persistent identifiers at appropriate levels for social science datasets, and developing and sharing best practices increasingly cross national boundaries and provide increasing opportunities for collaboration - between people and institutions in these two nations, and well beyond.

description: We present a procedure inspired by dense coding, which enables a highly efficient transmission of information of a continuous nature. The procedure requires the sender and the recipient to share a maximally entangled state. We deal with the concrete problem of aligning reference frames or trihedra by means of a quantum system. We find the optimal covariant measurement and compute the corresponding average error, which has a remarkably simple close form. The connection of this procedure with that of estimating unitary transformations on qubits is briefly discussed.

description: The concept of quantum complexity has far-reaching implications spanning theoretical computer science, quantum many-body physics, and high energy physics. The quantum complexity of a unitary transformation or quantum state is defined as the size of the shortest quantum computation that executes the unitary or prepares the state. It is reasonable to expect that the complexity of a quantum state governed by a chaotic many-body Hamiltonian grows linearly with time for a time that is exponential in the system size; however, because it is hard to rule out a short-cut that improves the efficiency of a computation, it is notoriously difficult to derive lower bounds on quantum complexity for particular unitaries or states without making additional assumptions. To go further, one may study more generic models of complexity growth. We provide a rigorous connection between complexity growth and unitary $k$-designs, ensembles which capture the randomness of the unitary group. This connection allows us to leverage existing results about design growth to draw conclusions about the growth of complexity. We prove that local random quantum circuits generate unitary transformations whose complexity grows linearly for a long time, mirroring the behavior one expects in chaotic quantum systems and verifying conjectures by Brown and Susskind. Moreover, our results apply under a strong definition of quantum complexity based on optimal distinguishing measurements.

description: This paper analyzed the impact of economic slowdown on rice consumption in Asia using a partial equilibrium model following the assumptions of a decline in income and constant world oil prices. Simulation results suggested that with a 5% drop in real per capita GDP and constant world oil prices, rice consumption in Asia would increase. However, the overall increase in rice consumption due to decline in income is pulled down by positive income elasticity in Bangladesh, Cambodia, Myanmar, Pakistan and the Philippines.

description: We present a new ground-based visual transmission spectrum of the hot Jupiter WASP-43b, obtained as part of the ACCESS Survey. The spectrum was derived from four transits observed between 2015 and 2018, with combined wavelength coverage between 5,300 Å-9,000 Å and an average photometric precision of 708 ppm in 230 Å bins. We perform an atmospheric retrieval of our transmission spectrum combined with literature HST/WFC3 observations to search for the presence of clouds/hazes as well as Na, K, H$α$, and $\rm H_2O$ planetary absorption and stellar spot contamination over a combined spectral range of 5,318 Å-16,420 Å. We do not detect a statistically significant presence of Na I or K I alkali lines, or H$α$ in the atmosphere of WASP-43b. We find that the observed transmission spectrum can be best explained by a combination of heterogeneities on the photosphere of the host star and a clear planetary atmosphere with $\rm H_2O$. This model yields a log-evidence of $8.26\pm0.42$ higher than a flat (featureless) spectrum. In particular, the observations marginally favor the presence of large, low-contrast spots over the four ACCESS transit epochs with an average covering fraction $f_\text{het} = 0.27^{+0.42}_{-0.16}$ and temperature contrast $ΔT = 132\text{ K} \pm 132\text{ K}$. Within the planet's atmosphere, we recover a log $\rm H_2O$ volume mixing ratio of $-2.78^{+1.38}_{-1.47}$, which is consistent with previous $\rm H_2O$ abundance determinations for this planet.

description: For most applications, zirconia (ZrO2) is doped with yttria. Doping leads to the stabilization of the tetragonal or cubic phase, and increased oxygen ion conductivity. Most previous surface studies of yttria-doped zirconia were plagued by impurities, however. We have studied doping of pure, 5-monolayer ZrO2 films on Rh(111) by x-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy (STM), and low-energy electron diffraction (LEED). STM and LEED show that the tetragonal phase is stabilized by unexpectedly low dopant concentrations, 0.5 mol% Y2O3, even when the films are essentially fully oxidized (as evidenced by XPS core level shifts). XPS also shows Y segregation to the surface with an estimated segregation enthalpy of $-23 \pm 4$\,kJ/mol.

description: We analyse the anisotropy of the cosmic microwave background (CMB) in hyperbolic universes possessing a non-trivial topology with a fundamental cell having an infinitely long horn. The aim of this paper is twofold. On the one hand, we show that the horned topology does not lead to a flat spot in the CMB sky maps in the direction of the horn as stated in the literature. On the other hand, we demonstrate that a horned topology having a finite volume could explain the suppression of the lower multipoles in the CMB anisotropy as observed by COBE and WMAP.

description: We estimate whether there are productivity gains from ultrafast broadband (UFB) adoption and whether any gains are higher when firms undertake complementary organisational investments. Using an IV strategy based on proximity to schools (that were targeted in the UFB roll-out), we find that the average effect of UFB adoption on employment and (labour and multifactor) productivity is insignificantly different from zero, even for firms in industries where we might expect the returns to UFB to be relatively high. Conversely, we find that firms making concurrent investments in organisational capital specifically for the purpose of getting more from their ICTs appear to experience higher productivity growth, at least in first-difference specifications. Firms making these joint (UFB-organisational) investment decisions are significantly more likely to report other positive outcomes from their ICT investments, consistent with the identified relationship with productivity being causal.

description: Statistical knowledge is one of the main competences of next generation specialists. One by one country declared statistical education as a national priority and launched programs to improve teaching and training in data understanding and analysis. Universities play a leading role. Following other countries Russian university community is working to enhance statistical education. First step is to compose modern statistical information infrastructure. The core is databases designed and maintained under the Moscow State University-based Information System RUSSIA The databases keep social and economic indicators at regional and local levels with annual and monthly update and are complimented by graphics- and map-based data visualization. System and comparative analysis tools are accomplished. Tutorials are implemented to train users. The first one is available to assist in evidence-based investigations in public administration. Work underway is on public administration domain ontology to integrate statistical indicators and analytical publications. The databases are available for free to all RF universities, colleges, think tanks, academic institutes, NGO, public libraries, specialists and citizens and serve for statistical culture dissemination in Russian society. The resource is of special value for local level powers - Russian national statistical agency Rosstat has only 3 years ago started to publish local level data. The UIS RUSSIA databases provide for more developed analytical services.

description: Herein, ultrasonic-assisted liquid phase micro-extraction in tandem with dispersive µ-solid-phase extraction was utilised for the determination of atrazine at µg L−1 concentration levels. Initially, a liquid phase micro-extraction based on dispersion of organic solvent was used for the rapid extraction of atrazine from aqueous solution followed by the extraction organic solvent effectively collected from the solution by using C-18-magnetic nanoparticles without any requirement to centrifugation step. After the elution of the extracted targets from the magnetic nanoparticles, atrazine concentration was monitored by high-performance liquid chromatography with Ultraviolet detector at µg L−1 level. The influencial parameters in the pre-concentration step were as follows: pH of solution, magnetic-based sorbent amount (mg) and 1-octanol volume (µL). Additionally, the selected data for the factors produced by the Box-Behnken design were: pH of sample: 9.0, sorbent amount: 22 mg and the extraction solvent volume: 36 µL. Relative standard deviations under the optimised conditions by the hybrid mentioned extraction method was determined to be <7% and the method detection limit for atrazine was calculated to be 0.3 µg L−1. Limit of quantification was calculated to be 0.8 µg/L for the studied analyte.
The Orbit, Mass, and Albedo of Transneptunian Binary 1999 RZ253

description: We have observed 1999 RZ253 with the Hubble Space Telescope at seven separate epochs and have fit an orbit to the observed relative positions of this binary. Two orbital solutions have been identified that differ primarily in the inclination of the orbit plane. The best fit corresponds to an orbital period, P=46.263 +0.006/-0.074 days, semimajor axis a=4,660 +/-170 km and orbital eccentricity e=0.460 +/-0.013 corresponding to a system mass m=3.7 +/-0.4 x10^18 kg. For a density of rho = 1000 kg m^-3 the albedo at 477 nm is p = 0.12 +/-0.01, significantly higher than has been commonly assumed for objects in the Kuiper Belt. Multicolor, multiepoch photometry shows this pair to have colors typical for the Kuiper belt with a spectral gradient of 0.35 per 100 nm in the range between 475 and 775 nm. Photometric variations at the four epochs we observed were as large as 12 +/-3% but the sampling is insufficient to confirm the existence of a lightcurve.

Next-to-leading order QCD calculations with parton showers II: soft singularities
Creators: name: Soper, Davison E.
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Programs that calculate observables in quantum chromodynamics at next-to-leading order typically generate events that consist of partons rather than hadrons -- and just a few partons at that. These programs would be much more useful if the few partons were turned into parton showers, which could be given to one of the Monte Carlo event generators to produce hadron showers. In a previous paper, we have seen how to generate parton showers related to the final state collinear singularities of the perturbative calculation for the example of e+ + e- --> 3 jets. This paper discusses the treatment of the soft singularities.

description: We present ISM and CGM metallicities for 25 absorption systems associated with isolated star-forming galaxies (=0.28) with 9.417.2) reside along the minor axis. This suggest N(HI) could be a useful indicator of accretion/outflows. We conclude that CGM is not well mixed, given the range of galaxy-CGM metallicities, and that metallicity at low redshift might not be a good tracer of CGM processes. Furthermore we should replace integrated line-of-sight, single phase, metallicities with multi-phase, cloud-cloud metallicities, which could be more indicative of the physical processes within the CGM.

description: Studies on the economics of agricultural production in organic farms are carried out on a small scale but deliver important information about the situation of organic agricultural producers. The aim of this paper is to examine the economic and production results of organic farms cultivating winter wheat and winter rye in relation to the results of conventional farms (by way of case study). The paper used actual accounting data collected in the Agrokoszty system and Polish FADN and direct interviews with organic farmers. For detailed comparison of the economic results the methodology of calculating gross margin was used. When compared to conventional farms, the winter wheat and winter rye production results were weaker in organic farms, and a lower yield of grain was demonstrated. The selling price of organic grain was more favourable only for winter wheat. The surveyed farmers indicate the will to continue organic production. However, it is necessary to develop the organic product market and for further financial support for this production sector.

description: Public safety power shutoffs (PSPS) are a common pre-emptive measure to reduce wildfire risk due to power system equipment. System operators use PSPS to de-energize electric grid elements that are either prone to failure or located in regions at a high risk of experiencing a wildfire. Successful power system operation during PSPS involves coordination across different time scales. Adjustments to generator commitments and transmission line de-energizations occur at day-ahead intervals while adjustments to load servicing occur at hourly intervals. Generator commitments and operational decisions have to be made under uncertainty in electric grid demand and wildfire potential forecasts. This paper presents deterministic and two-stage mean-CVaR stochastic frameworks to show how the likelihood of large wildfires near transmission lines affects generator commitment and transmission line de-energization strategies. The optimal costs of commitment, operation, and lost load on the IEEE 14-bus test system are compared to the costs generated from prior optimal power shut-off (OPS) formulations. The proposed mean-CVaR stochastic program generates less total expected costs evaluated with respect to higher demand scenarios than costs generated by risk-neutral and deterministic methods.
