description: Many physical, chemical, and biological systems depend on the first passage time (FPT) of a diffusive searcher to a target. Typically, this FPT is much slower than the characteristic diffusion timescale. For example, this is the case if the target is small (the narrow escape problem) or if the searcher must escape a potential well. However, many systems depend on the first time a searcher finds the target out of a large group of searchers, which is the so-called extreme FPT. Since this extreme FPT vanishes in the limit of many searchers, the prohibitively slow FPTs of diffusive search can be negated by deploying enough searchers. However, the notion of "enough searchers" is poorly understood. How can one determine if a system is in the slow regime (dominated by small targets or a deep potential, for example) or the fast regime (dominated by many searchers)? How can one estimate the extreme FPT in these different regimes? In this paper, we answer these questions by deriving conditions which ensure that a system is in either regime and finding approximations of the full distribution and all the moments of the extreme FPT in these regimes. Our analysis reveals the critical effect that initial searcher distribution and target reactivity can have on extreme FPTs.

description: The concentration of greenhouse gases in the atmosphere has grown mainly as a result of human activity in the world. Anthropogenic CO2 emission accounts for around three-fourths of global GHG emissions. Furthermore, the development of greenhouse gas emissions is extremely associated with global warming. Approximately one-third of the global atmospheric methane emissions come from agricultural activities. In the agricultural production process, irrational activities such as inappropriate land use, the excessive application of pesticides and chemical fertilizers may lead to the release of high amounts of GHG emissions, which affect harmfully the environment. In addition, the intensity of agriculture-related factors of climate change might vary over countries and continents. The objective of the research is to explore the main agricultural-related determinants of climate change focusing on livestock farming, crop production, land use, enteric fermentation, manure management, synthetic fertilizers along with the geographical and cultural background of the pollution. The analysis was carried out on a global sample, representing the world economy.

Basidiome resupinate, whitish, adnate, very thin, margin abrupt. Hyphal system monomitic, hyphae hyaline, with clamps. Hymenium a dense palisade of basidia, gloeocystidia, and lamprocystidia. Gloeocystidia abundant, tubular, often with a rooted base, few with an apical schizopapilla, 40–60 × 8–10 µm, distinctly thick-walled except at the apex, walls thickened up to 3 µm, with oleose contents. Lamprocystidia conical, mostly 25–35 × 10–15 µm, encrustation and basal part hyaline, less abundant than gleocystidia. Basidia clavate, 25–30 × 6–8 µm, with four sterigmata, with a basal clamp. Basidiospores cylindrical to suballantoid, 6.5–8 × 2.5–3 µm, smooth, hyaline, IKI- (Fig. 11).
 The species is characterized above all by the thick-walled gloeocystidia, often rooted at the base. The lamprocystidia, presence of clamps, and suballantoid basidiospores are also diagnostic. It is morphologically closely related to Peniophora crassitunicata Boidin, Lanq. & Gilles that differs in having much larger gloeocystidia and slightly smaller basidiospores. Martínez & Nakasone (2011) reported Peniophora crassitunicata from Uruguay. Peniophora bonariensis was recorded from northern Argentina (Gómez & Loewenbaum 1976) and Guadeloupe (Boidin et al. 1991).

description: Rural water/sewer facilities generate private investment and public funds, and increase the property tax base. But the average urban water/sewer facility, which costs only about one-third more than the average rural facility, creates about twice the amount of permanent jobs, induces three times more private investment, leverages twice as much in public funds, and adds three times more to the local property tax base. This difference may be due to greater aggregate infrastructure in urban than in small rural communities.

description: We consider the out-of-equilibrium (quasi-) particle number distributions of the Higgs and W-fields during electroweak tachyonic preheating. We model this process by a fast quench, and perform classical real-time lattice simulations in the SU(2)-Higgs model in three dimensions. We discuss how to define particle numbers and effective energies using two-point functions in Coulomb and unitary gauge, and consider some of the associated problems. After an initial exponential growth in effective particle numbers, the system stabilises, allowing us to extract effective masses, temperatures and chemical potentials for the particles.

description: Theoretically the legislation of Medical Assistance in Dying, hereafter MAiD, ensures all Canadians can exercise their right to die. In reality, the new politics around death provides nothing remotely resembling autonomy in dying in either the procedural or personal sense. Scripting death proposes autonomous architecture. Through assisted dying, it renders death as an anticipated event. When one actively makes death instead of let die, dying becomes a liberating process of choice and control.

description: The strength and vertical distribution of atmospheric turbulence is a key factor determining the performance of optical and infrared telescopes, with and without adaptive optics. Yet, this remains challenging to measure. We describe a new technique using a sequence of short-exposure images of a star field, obtained with a small telescope. Differential motion between all pairs of star images is used to compute the structure functions of longitudinal and transverse wavefront tilt for a range of angular separations. These are compared with theoretical predictions of simple turbulence models by means of a Markov-Chain Monte-Carlo optimization. The method is able to estimate the turbulence profile in the lower atmosphere, the total and free-atmosphere seeing, and the outer scale. We present results of Monte-Carlo simulations used to verify the technique, and show some examples using data from the second AST3 telescope at Dome A in Antarctica.

description: In the current study, a novel and facile selective colorimetric approach was developed by Eriochrome Black T (EBT) for naked-eye detection and determination of nickel (Ni2+) and cyanide (CN−) ions in H2O/DMSO (9:1, v/v) media. The chemosensing behaviour of EBT has been indicated through UV-Vis absorbance spectra, visual colour changes, and FTIR spectra. First, EBT could selectively identify Ni2+ over other competitive cation in 90% aqueous media and then, the resulting EBT-Ni2+complex was successfully applied for selective colorimetric recognition of CN− based on azo-hydrazone tautomeric skeletons. The detection limit of EBT towards Ni2+ and CN− were calculated to be 0.06 µmol L−1 and 0.15 µmol L−1, respectively. These consequences represent an innovative type of nimble chemosensor for manifold target ions using simple colorimetric and sequential detection. When operated by chemical ions Ni2+ and CN− can act as an absorbance switch, distinguishing a multi-addressable system. In addition, INVERTER (INV) and INHIBIT (INH) logic gates at different wavelengths and a keypad lock were created by applying chemical ions Ni2+ and CN− as two inputs and an absorption mode at 541 nm as an output on the basis of suitable chemical stimuli.

description: We study a three-dimensional chiral second order topological insulator (SOTI) subject to a magnetic field. Via its gauge field, the applied magnetic field influences the electronic motion on the lattice, and via the Zeeman effect, the field influences the electronic spin. We compare two approaches to the problem: an effective surface theory, and a full lattice calculation. The surface theory predicts a massive Dirac spectrum on each of the gapped surfaces, giving rise to Landau levels once the surfaces are pierced by magnetic flux. The surface theory qualitatively agrees with our lattice calculations, accurately predicting the surface gap as well as the spin and orbital components of the states at the edges of the surface Dirac bands. In the context of the lattice theory, we calculate the spectrum with and without magnetic field and find a deviation from the surface theory when a gauge field is applied. The energy of the lowest-lying Landau level is found closer to zero than is predicted by the surface theory, which leads to an observable magnetotransport signature: inside the surface gap, there exist different energy regions where either one or two chiral hinge modes propagate in either direction, quantizing the differential conductance to either one or two conductance quanta.

description: Coumarin derivatives are used in a wide range of applications, such as optoelectronics, photovoltaics and dye lasers. Therefore they have attracted significant research interest. In this regard, novel coumarin dye molecules were synthesised and characterised by spectroscopic techniques. The synthesised dyes were studied for optical (linear and nonlinear), frontier molecular orbital analysis (using cyclic voltammetry and DFT calculations) and the current-voltage (I-V) studies for photosensitization behaviour on TiO2 nanoparticles. The TiO2 nanoparticles were synthesised by the sol-gel method and characterised by XRD, EDAX and SEM analysis. The results showed that the dye molecules possess good light-absorbing capability with a high molar absorption coefficient and also exhibited the good nonlinear optical (NLO) response. Moreover, the I-V characteristics suggest the efficacy of synthesised dyes for photovoltaic applications.

description: Of all private U.S. agricultural land, Whites account for 96 percent of the owners, 97 percent of the value, and 98 percent of the acres. Nonetheless, four minority groups (Blacks, American Indians, Asians, and Hispanics) own over 25 million acres of agricultural land, valued at over $44 billion, which has wide-ranging consequences for the social, economic, cultural, and political life of minority communities in rural America. This article presents the most recent national data available on the racial and ethnic dimensions of agricultural land ownership in the United States, based largely on USDA’s Agricultural Economics and Land Ownership Survey of 1999.

description: What do researchers need from archives? What do archives need from researchers? These questions cover two types of researchers that encounter data archives: data creators and data reusers. These groups have different needs and it is archives that mediate between them. The role of an archive for creators is to support them in producing quality data, metadata and documentation and to facilitate wide and multipurpose data dissemination. By supporting multipurpose reuse to the fullest extent possible, archives help realise the value of public investment in academic research. This paper discusses the optimisation of research data management training and support for research data creators and data dissemination and long-term preservation for social science data archives. It outlines the GESIS plan to create a research data management and archive training centre for the cessda-ERIC European research area, to cater for both data supply and data demand. The training centre will look to ensure excellence in the creation and long-term preservation of reusable data in the cessda-ERIC area, contribute to promoting and adaptating standards in research data management and promote data availability and reuse. Finaly, the centre will provide and coordinate training on technologies and tools used by data professionals.

description: In recent years, there have been many reports on the presence of organic compounds in different compartments of the aquatic environment. The subject of our research was the development of a new method for the determination of selected organic micropollutants and their transformation products in wastewater samples. A rapid and sensitive ultra-high performance liquid chromatographic method coupled with tandem mass spectrometry has been developed and used for the separation and determination of 1H-benzotriazole, imidacloprid and clarithromycin in wastewater samples. The analytes were separated on a ZORBAX SB-C3 column with a gradient elution within 3.0 min. The analytes were isolated from wastewater samples by solid-phase extraction. Extraction was carried out on the Oasis HLB cartridges and methanol:acetone (1:1, v/v) was used for elution. The working ranges of the developed method were 1–100 ng L−1. The recovery ranged from 62% to 102% and intra- and inter-day precision was lower than 13% for all analytes. Finally, the optimised method was applied for the determination of the organic micropollutants in wastewater samples: (artificial) raw wastewater, wastewater treated using aerated activated sludge method and wastewater from an Upper Silesia wastewater treatment plant. In addition, transformation products of the analytes in the treated wastewater samples were tentatively identified.

description: The composition of sugarcane vinasse varies according to the substrate of alcoholic fermentation, e.g. if it is sugarcane juice and/or molasses. Regardless of the origin, the main organic compounds found in sugarcane vinasse are organic acids, alcohols and a low amount of carbohydrates. To access the organic composition of such wastewater, the present paper describes a high-performance liquid chromatography (HPLC) separation method coupled to a Refractive Index Detector (RID) in order to quantify the organic acids (C1 to C6) and alcohols in sugarcane vinasse. The analysed substances were acetic acid, butyric acid, caproic acid, citric acid, lactic acid, propionic acid, succinic acid, valeric acid, butanol, ethanol, glycerol and methanol. A validation study of the method was performed taking into account the matrix effect exerted by vinasse samples in natura. In conclusion, it was proved that the method is suitable for assessing the organic composition of vinasse: able to separate 12 analytes, with excellent linearity (R2 > 0.999), with adequate working ranges, high precision (recovery ranging from 83% to 102%), and low matrix effects (<5%).

description: We present the results of mid-infrared nulling interferometric observations of the main-sequence star alpha Lyr (Vega) using the 6.5 m MMT with its adaptive secondary mirror. From the observations at 10.6 microns, we find that there is no resolved emission from the circumstellar environment (at separations greater than 0.8 AU) above 2.1% (3 sigma limit) of the level of the stellar photospheric emission. Thus, we are able to place an upper limit on the density of dust in the inner system of 650 times that of our own solar system's zodiacal cloud. This limit is roughly 2.8 times better than those determined with photometric excess observations such as those by IRAS. Comparison with far-infrared observations by IRAS shows that the density of warm dust in the inner system (< 30 AU) is significantly lower than cold dust at larger separations. We consider two scenarios for grain removal, the sublimation of ice grains and the presence of a planetary mass "sweeper." We find that if sublimation of ice grains is the only removal process, a large fraction (> 80%) of the material in the outer system is ice.

Type species.
Apiocephalus punctipennis Gahan, 1898.
Redescription.
Head prolonged, markedly narrowed behind eyes; eyes prominent, coarsely faceted. Antennae longer than body; scape long and curved, thickened apically; antennomere 3 approximately equal in length to antennomere 4 but distinctly shorter than antennomere 5; antennomeres 5–10 gradually decreasing in length. Pronotum strongly narrowed anteriorly, constricted before apex, with two developed lateral spines; disc provided with four protuberances, of which the anterior two are before middle, low, and the posterior two are after middle, strongly ridged. Elytra much broader than pronotum, with sides subparallel in basal two-thirds, thence converging more strongly towards apices which are truncate. Male metatarsomere 1 approximately as long as metatarsomere 2 and 3 combined.
Distribution.
Kenya, India, China (new country record).
Remarks.
This genus was first found in “ British East Africa ” (now part of Kenya). The second species was discovered in northern India. The third species, to be described below, comes from central China. This scattered distribution suggests that the genus exhibits a continental distribution pattern. It also indicates that with further research, additional new taxa may be discovered across the continents of Africa, Europe and Asia.

description: We propose a diagnostic for finite temperature topological order using `topological entanglement negativity', the long-range component of a mixed-state entanglement measure. As a demonstration, we study the toric code model in $d$ spatial dimension for $d$=2,3,4, and find that when topological order survives thermal fluctuations, it possesses a non-zero topological entanglement negativity, whose value is equal to the topological entanglement entropy at zero temperature. Furthermore, we show that the Gibbs state of 2D and 3D toric code at any non-zero temperature, and that of 4D toric code above a certain critical temperature, can be expressed as a convex combination of short-range entangled pure states, consistent with the absence of topological order.

description: We investigate the low-energy properties of antiferromagnetic quantum XXZ spin chains with couplings following two-letter aperiodic sequences, by an adaptation of the Ma-Dasgupta-Hu renormalization-group method. For a given aperiodic sequence, we argue that in the easy-plane anisotropy regime, intermediate between the XX and Heisenberg limits, the general scaling form of the thermodynamic properties is essentially given by the exactly known XX behavior, providing a classification of the effects of aperiodicity on XXZ chains. As representative illustrations, we present analytical and numerical results for the low-temperature thermodynamics and the ground-state correlations for couplings following the Fibonacci quasiperiodic structure and a binary Rudin-Shapiro sequence, whose geometrical fluctuations are similar to those induced by randomness.

description: Scenarios in which the knee of the cosmic ray spectrum depends on the particle rigidities usually predict that the cosmic ray composition becomes heavier above the knee and have associated a change in the spectral slope of each individual nuclear component which is steeper than the change ($Δα\simeq 0.3$) observed in the total spectrum. We show that this implies that the very high energy ($E_ν>10^{14}$ eV) diffuse neutrino fluxes produced by cosmic rays hitting the atmosphere or colliding with the interstellar medium in the Galaxy will be significantly suppressed, making their detection harder but also reducing the background for the search of other (more challenging) astrophysical neutrino sources.

description: Anomalous subdiffusion characterizes transport in diverse physical systems and is especially prevalent inside biological cells. In cell biology, the prevailing model for chemical activation rates has recently changed from the first passage time (FPT) of a single searcher to the FPT of the fastest searcher out of many searchers to reach a target, which is called an extreme statistic or extreme FPT. In this paper, we investigate extreme statistics of searchers which move by anomalous subdiffusion. We model subdiffusion by a fractional Fokker-Planck equation involving the Riemann-Liouville fractional derivative. We prove an explicit and very general formula for every moment of subdiffusive extreme FPTs and approximate their full probability distribution. While the mean FPT of a single subdiffusive searcher is infinite, the fastest subdiffusive searcher out of many subdiffusive searchers typically has a finite mean FPT. In fact, we prove the counterintuitive result that extreme FPTs of subdiffusion are faster than extreme FPTs of normal diffusion. Mathematically, we employ a stochastic representation involving a random time change of a standard Ito drift-diffusion according to the trajectory of the first crossing time inverse of a Levy subordinator. A key step in our analysis is generalizing Varadhan's formula from large deviation theory to the case of subdiffusion, which yields the short-time distribution of subdiffusion in terms of a certain geodesic distance.

Data Management Training to Support Faculty Research Needs: Lessons Learned
Creators: name: Womack, Ryan
Publisher: name: Zenodo
Year: 2012

description: To build the skills of its Data Team, the Rutgers University Libraries have developed an internal Research Data Management course. The RUresearch Data Team brings together subject librarians, metadata librarians, and the technical staff working with the RUresearch data portal. The goal of the course is to instill in all team members a baseline knowledge of all aspects of data management necessary to support faculty's research data needs. The entire team meets together approximately monthly for a two hour class. In between class sessions, group homework assignments and discussion reinforce the concepts. The class modules cover these topics and more: the data model; metadata; controlled vocabularies, ontologies, and linked data; data preservation and reuse; the data lifecycle; use cases; designing a research portal; and workflow management. The presentation will present the findings from interviews of course participants and instructors that explore their reactions to the course. What do subject librarians without prior exposure to data issues take away from it? How does learning about the data needs of researchers affect technical staff? What lessons did the Libraries learn from running such a course? This presentation will provide the answers.

description: The composition of sugarcane vinasse varies according to the substrate of alcoholic fermentation, e.g. if it is sugarcane juice and/or molasses. Regardless of the origin, the main organic compounds found in sugarcane vinasse are organic acids, alcohols and a low amount of carbohydrates. To access the organic composition of such wastewater, the present paper describes a high-performance liquid chromatography (HPLC) separation method coupled to a Refractive Index Detector (RID) in order to quantify the organic acids (C1 to C6) and alcohols in sugarcane vinasse. The analysed substances were acetic acid, butyric acid, caproic acid, citric acid, lactic acid, propionic acid, succinic acid, valeric acid, butanol, ethanol, glycerol and methanol. A validation study of the method was performed taking into account the matrix effect exerted by vinasse samples in natura. In conclusion, it was proved that the method is suitable for assessing the organic composition of vinasse: able to separate 12 analytes, with excellent linearity (R2 > 0.999), with adequate working ranges, high precision (recovery ranging from 83% to 102%), and low matrix effects (<5%).

description: We present a covariant description of non-vacuum static spherically symmetric spacetimes in $f(R)$ gravity applying the (1+1+2) covariant formalism. The propagation equations are then used to derive a covariant and dimensionless form of the Tolman-Oppenheimer-Volkoff (TOV) equations. We then give a solution strategy to these equations and obtain some new exact solutions for the particular case $f(R)=R+αR^{2}$, which have the correct thermodynamic properties for standard matter.

description: We consider two coupled generic quantum dots, each modelled by a simple potential which allows the derivation of an analytical expression for the inter-dot Foerster coupling, in the dipole-dipole approximation. We investigate the energy level behaviour of this coupled two-dot system under the influence of an external applied electric field and predict the presence of anticrossings in the optical spectra due to the Foerster interaction.

description: China’s trade with the United States has boomed since the 1980s. China exports a number of products such as apparel, furniture, and plastics that compete with products manufactured in rural America. However, many of China’s most important exports, like footwear and toys, are not widely produced in rural America. China’s exports of products like footwear and toys benefit rural U.S. consumers by keeping prices low. China’s growing economy is creating market opportunities for rural U.S. producers of oilseeds, grain, meat, machinery, and equipment.

description: Computable Information Density (CID), the ratio of the length of a losslessly compressed data file to that of the uncompressed file, is a measure of order and correlation in both equilibrium and nonequilibrium systems. Here we show that correlation lengths can be obtained by decimation - thinning a configuration by sampling data at increasing intervals and recalculating the CID. When the sampling interval is larger than the system's correlation length, the data becomes incompressible. The correlation length and its critical exponents are thus accessible with no a-priori knowledge of an order parameter or even the nature of the ordering. The correlation length measured in this way agrees well with that computed from the decay of two-point correlation functions $g_{2}(r)$ when they exist. But the CID reveals the correlation length and its scaling even when $g_{2}(r)$ has no structure, as we demonstrate by "cloaking" the data with a Rudin-Shapiro sequence.

description: It is important to conduct a research on Empowerment Model of Removed Society Caused by Nipah Dam Development through partnership program in Sampang-Madura, since this dam uses around 357.073 ha spread into 7 villages. It causes many people must be removed from their houses and they have no land anymore. The condition of society is in poor condition, refers to low education (only in third class in Elementary school) and low income. From this phenomenon, it is important to find a good solution in society empowerment program. This research was conducted for three years from 2006 – 2008. There are many methods in this research. Implementation and review of empowerment model used method of participatory action research. Further, to come out with participatory partnership model, researcher used participatory rural appraisal by conducting focus group discussion. Then, the researcher tabulate, analyze and interpret the data. Results of a three-year-research are model of community empowerment around Nipah Dam, concept of partnership network and model of development small and medium enterprise and cooperative. Summaries of the research are: (a) Empowerment model needs Local human resources skill (b) Effective empowerment model needs good coordination of all parties, has certain purpose and continous socialization, capable assistances and facilitators, and also a clear program in order it is easily understood, (c) partnership network needs coordination between goverment, university, NGOs and stakeholder Recommendations of the research are : (a) it is needed the availability of partnership network from distric, sub distric and village level, (b) it is needed a clearly role sharing between goverment, univesity, NGOs and stakeholder (c) it is needed the improvement local product competitiveness.
