description: Infectious diseases are considered major threats to biodiversity, however strategies to mitigate their impacts in the natural world are scarce and largely unsuccessful. Chytridiomycosis is responsible for the decline of hundreds of amphibian species worldwide, but an effective disease management strategy that could be applied across natural habitats is still lacking. In general amphibian larvae can be easily captured, offering opportunities to ascertain the impact of altering the abundance of hosts, considered to be a key parameter affecting the severity of the disease. Here, we report the results of two experiments to investigate how altering host abundance affects infection intensity in amphibian populations of a montane area of Central Spain suffering from lethal amphibian chytridiomycosis. Our laboratory-based experiment supported the conclusion that varying density had a significant effect on infection intensity when salamander larvae were housed at low densities. Our field experiment showed that reducing the abundance of salamander larvae in the field also had a significant, but weak, impact on infection the following year, but only when removals were extreme. While this suggests adjusting host abundance as a mitigation strategy to reduce infection intensity could be useful, our evidence suggests only heavy culling efforts will succeed, which may run contrary to objectives for conservation.

description: Heterogeneous nature of real networks implies that different edges play different roles in network structure and functions, and thus to identify significant edges is of high value in both theoretical studies and practical applications. We propose the so-called second-order neighborhood (SN) index to quantify an edge's significance in a network. We compare SN index with many other benchmark methods based on 15 real networks via edge percolation. Results show that the proposed SN index outperforms other well-known methods.

The main differences are outlined and the consequences of imposing beta-stability in these models are discussed.

description: Presented is a characterization of travel speed on any roadway segment based on probe vehicle position data. Most of the characterization is based position data obtained from GPS receivers because of their high precision and their increasing availability. Comparison is also made to Qualcomm’s Automatic Satellite Position Reporting (QASPR) system because of its long history (10+ years) of extensive use by the long-haul trucking industry. Described is the use of these data in conjunction with digital map representations of roadways with particular reference to ALK’s digital map database of North America. Two examples of the use of probe vehicle based GPS data to ascertain and monitor speed on roadway segments are presented. One is a demonstration of the monitoring of the speed performance of the various road segments that make up the Québec-Windsor corridor. Extensive GPS data from the first half of 2008 characterize the speed performance of the corridor by day-of-week and time-of-day. The second example also uses GPS probe vehicle data to assign a median speed , by direction, to all 31 million arcs of ALK’s digital map database of North America. Examples of that assignment are displayed in geographic bandwidth charts and a generic example of a fastest route computed based on the assigned median speeds is presented.

description: Presented is an analysis of a large volume of readily available loop detector based traffic data for the Los Angeles and Ventura Counties. The data suggests that the daily temporal variation of congestion along any directional road segment can be characterized quite well by a 10-parameter function. The function is shown to be suitable for use in the classification of road segments, such as having morning but no afternoon or evening congestion, as well as for the purpose of improving real-time forecasts of congestion ahead for use in generating dynamic real-time minimum estimated time-of-arrival turn-by- turn navigation instructions. Automation of the process allows for the characterization of all of the Los Angeles and Ventura Counties and can be applied to any metropolitan area having similar data. Several interactive and dynamic visualization tools using Google Earth are also developed and presented.

description: We investigate the resonant two-magnon Raman scattering in two-dimensional (2D) Mott insulators by using a half-filled 2D Hubbard model in the strong coupling limit. By performing numerical diagonalization calculations for small clusters, we find that the Raman intensity is enhanced when the incoming photon energy is not near the optical absorption edge but well above it, being consistent with experimental data. The absence of resonance near the gap edge is associated with the presence of background spins, while photoexcited states for resonance are found to be characterized by the charge degree of freedom. The resonance mechanism is different from those proposed previously.

description: The three-dimensional abelian Higgs model has been argued to be dual to a scalar field theory with a global U(1) symmetry. We show that this duality, together with the scaling and universality hypotheses, implies a scaling law for the magnetic permeablity chi_m near the line of second order phase transition: chi_m ~ t^nu, where t is the deviation from the critical line and nu ~ 0.67 is a critical exponent of the O(2) universality class. We also show that exactly on the critical lines, the dependence of magnetic induction on external magnetic field is quadratic, with a proportionality coefficient depending only on the gauge coupling. These predictions provide a way for testing the duality conjecture on the lattice in the Coulomb phase and at the phase transion.

description: The derivation of effective spin models describing the low energy magnetic properties of undoped CuO_2-planes is reinvestigated. Our study aims at a quantitative determination of the parameters of effective spin models from those of a multi-band model and is supposed to be relevant to the analysis of recent improved experimental data on the spin wave spectrum of La_2CuO_4. Starting from a conventional three-band model we determine the exchange couplings for the nearest and next-nearest neighbor Heisenberg exchange as well as for 4- and 6-spin exchange terms via a direct perturbation expansion up to 12th (14th for the 4-spin term) order with respect to the copper-oxygen hopping t_pd. Our results demonstrate that this perturbation expansion does not converge for hopping parameters of the relevant size. Well behaved extrapolations of the couplings are derived, however, in terms of Pade approximants. In order to check the significance of these results from the direct perturbation expansion we employ the Zhang-Rice reformulation of the three band model in terms of hybridizing oxygen Wannier orbitals centered at copper ion sites. In the Wannier notation the perturbation expansion is reorganized by an exact treatment of the strong site-diagonal hybridization. The perturbation expansion with respect to the weak intersite hybridizations is calculated up to 4th order for the Heisenberg coupling and up to 6th order for the 4-spin coupling. It shows excellent convergence and the results are in agreement with the Pade approximants of the direct expansion. The relevance of the 4-spin coupling as the leading correction to the nearest neighbor Heisenberg model is emphasized.

description: Abstract: Background: Crossover designs are commonly utilised in randomised controlled trials investigating treatments for long-term chronic illnesses. One problem with this design is its inherent repeated measures necessitate the availability of an estimate of the within-person standard deviation (SD) to perform a sample size calculation, which may be rarely available at the design stage of a trial. Interim sample size re-estimation designs can be used to help alleviate this issue by adapting the sample size mid-way through the trial, using accrued information in a statistically robust way. Methods: The AIM HY-INFORM study is part of the Informative Markers in Hypertension (AIM HY) Programme and comprises two crossover trials, each with a planned recruitment of 600 participants. The objective of the study is to test whether blood pressure response to first line antihypertensive treatment depends on ethnicity. An interim analysis is planned to reassess the assumptions of the planned sample size for the study. The aims of this paper are: (1) to provide a formula for sample size re-estimation in both crossover trials; and (2) to present a simulation study of the planned interim analysis to investigate alternative within-person SDs to that assumed. Results: The AIM HY-INFORM protocol sample size calculation fixes the within-person SD to be 8 mmHg, giving > 90% power for a primary treatment effect of 4 mmHg. Using the method developed here and simulating the interim sample size reassessment, if we were to see a larger within-person SD of 9 mmHg at interim, 640 participants for 90% power 90% of the time in the three-period three-treatment design would be required. Similarly, in the four-period four-treatment crossover design, 602 participants would be required. Conclusions: The formulas presented here provide a method for re-estimating the sample size in crossover trials. In the context of the AIM HY-INFORM study, simulating the interim analysis allows us to explore the results of a possible increase in the within-person SD from that assumed. Simulations show that without increasing the planned sample size of 600 participants, we can reasonably still expect to achieve 80% power with a small increase in the within-person SD from that assumed.

description: Summary of miRNA expression profiles shuffling effects. ROC analysis was performed to evaluate the performance of F6 and F4d variables, computed with simulated miRNA profiles, in distinguishing enriched/underrepresented genes in AGO2 or GW182-IP samples. Each panel reports the AUC values obtained with simulated variables. Each boxplot refers to AUC values obtained with a specific set of simulations, where the expression profile of a set of miRNAs was shuffled. The boxplot in the center was obtained by shuffling all miRNAs. The boxplots from the center to the right refer to simulations where all the miRNAs were shuffled with the exception of n top expressed miRNAs, n increasing in the right direction. The boxplots from the center to the left refer to simulations where all the miRNAs were shuffled with the exception of n low expressed miRNAs, n increasing in the left direction. The green horizontal line defines the AUC value obtained with the original miRNA expression profile. Boxplots are colored in red if less than 5% of the simulations reach the AUC original value, green otherwise. This file contains the following simulation results: A. Simulated F6 variable distinguishing AGO2 enriched vs underrepresented genes. B. Simulated F6 variable distinguishing GW182 enriched vs underrepresented genes. C. Simulated F4d variable distinguishing AGO2 enriched vs underrepresented genes. D. Simulated F6&F4d SVM model distinguishing AGO2 enriched vs underrepresented genes. (PDF 555 kb)

 Remarks. Pixell (1913: 78) reported Hydroides dipoma (as Eupomatus spinosus) from Suez. Zibrowius (1973b: 36) commented on the species’ disjunctive distribution, from the length of the south east Atlantic coast, without additional records from the Mediterranean or from the Indian Ocean or Red Sea; and with a single Indo-West-Pacific location, Suez. We agree with him that it is likely that the record at Suez is due to a ship-borne introduction. We have not enumerated Hydroides dipoma among the species reported from the Canal. However, due to the proximity of Suez to the southern opening of the canal, we would not be surprised if it were to be found in the canal.

description: Current accepted tools in risk assessment include techniques such as Fault and Event Tree analysis to predict the level of safety risk. To date, use of these tools at Grade Crossings has been limited and analysis has reverted to safety performance statistics to correlate results. There has been a missing link in modeling to be able to provide meaningful estimates of safety risk. Until now practitioners have been unable to use factors such as sighting, conspicuity, train speed, and human behavior characteristics within their numerical techniques. Working for Network Rail, the Railway operation company in the United Kingdom (UK) Halcrow has been using theoretical techniques to quantify safety risk at grade crossings. During this work we have applied a new tool in modeling safety risk, the Event Window. Using this concept, we have been able to relate variables such as sighting, user perception and predict human error against a timeline. The nearer a moving train to a grade crossing the less likely a user will cross in error. The advantage of this technique is that it takes into account the one common factor in past accidents, how users incorrectly judge train speed. In this paper we shall address the following questions: 􀂃 What is the benefit of quantifying the safety risk at a grade crossing? 􀂃 How do these risk assessments help organizations responsible for risk at grade crossings discharge their duties? 􀂃 What is the quality or usefulness of different types of evidence in building up these models? 􀂃 How can we improve on existing risk assessment techniques to make more informed and location specific decisions on grade crossing safety? 􀂃 How does the Event Window assist us in predicting safety risk?

description: Asymmetric nuclear matter at sub-saturation densities is shown to present only one type of instabilities. The associated order parameter is dominated by the isoscalar density and so the transition is of liquid-gas type. The instability goes in the direction of a restoration of the isospin symmetry leading to a fractionation phenomenon. These conclusions are model independent since they can be related to the general form of the asymmetry energy. They are illustrated using density functional approaches.

We then present a novel approach to adaptively choose target-oriented deceptive trajectories to deceive humans for multiple interactions. Additionally, we propose a new metric to evaluate deception on data collected from the users when interacting with the mobile robot simulator. We performed a user study to test our proposed adaptive deceptive algorithm, which shows that our algorithm deceives humans even for multiple interactions and it is more effective than random choice of deceptive strategies.

description: Aus Perspektive der Rechtsextremismusforschung wird Rassismus idR lediglich als Teil eines rechten Weltbildes einbezogen, jedoch nicht als Machtverhältnis. Umgekehrt wird aus Perspektive der Rassismusforschung Rechtsextremismus als Ausdruck von Rassismus verhandelt und ebenfalls nicht theoretisch miteinbezogen. Diese Studie wirft daher die Frage auf, wie Rassismus in rechten Diskursen strukturiert ist und versucht als Arbeit der politikwissenschaftlichen Rechtsextremismusforschung Rassismus als Machtverhältnis zu beleuchten und die beiden Forschungsgebiete somit anzunähern und eine Verhältnisbestimmung von Rassismus und Rechtsextremismus vorzunehmen. Gegenstand der Arbeit ist die Analyse von Rassismus in rechten Diskursen anhand von Berichterstattung in einschlägigen rechten Medien (JUNGE FREIHEIT, Sezession und COMPACT Magazin) zwischen 2015 und 2020. Möglich wird diese forschungsschwerpunkteübergreifende Analyse durch die Nutzung des poststrukturalistischen „What is the problem represented to be?“ (WPR) Ansatz von Carol Bacchi. Der ursprünglich aus der Politikfeldforschung stammende Ansatz ermöglicht, nicht nur durch sein offenes Analysekonzept die Anwendung auf anderen Gebieten, sondern erlaubt es durch die Orientierung an den Arbeiten Foucaults, insbesondere Machtverhältnisse und deren Auswirkungen im Diskurs zu fokussieren. Die Studie macht dabei vor allem deutlich, das Rassismus tragendes Element rechter Diskurse ist. Ohne ihn können existenzielle Teile der Diskurse nicht aufrechterhalten werden. Zentral für den Erhalt rechter Diskurse sind darüber hinaus Leerstellen in den Diskursen selbst. So müssen etwa Begriffe wie Rassismus und Rechtsextremismus in den rechten Diskursen zum Erhalt selbiger, inhaltsleer verbleiben. Ebenso kommt Verschwörungserzählungen und Krisennarrativen eine besondere Bedeutung zu, da sie als Klammern fungieren und verschiedene Aspekte rechter Diskurse miteinander verbinden können und/oder in der Lage sind Widersprüche zu überbrücken.

description: Incommensurate structures can be described by the Frenkel Kontorova model. Aubry has shown that, at a critical value K_c of the coupling of the harmonic chain to an incommensurate periodic potential, the system displays the analyticity breaking transition between a sliding and pinned state. The ground state equations coincide with the standard map in non-linear dynamics, with smooth or chaotic orbits below and above K_c respectively. For the standard map, Greene and MacKay have calculated the value K_c=.971635. Conversely, evaluations based on the analyticity breaking of the modulation function have been performed for high commensurate approximants. Here we show how the modulation function of the infinite system can be calculated without using approximants but by Taylor expansions of increasing order. This approach leads to a value K_c'=.97978, implying the existence of a golden invariant circle up to K_c' > K_c.

description: The difference in heating or cooling to power ratio between required demands for district networks and the proposed tri-generation system is the most challenging issue of the system configuration and design. In this work, an adjustable, novel tri-generation system driven by geothermal resources is proposed to supply the thermal energies of a specific district network depending on ambient temperature in Germany. The tri-generation system is a combination of a modified absorption refrigeration cycle and a Kalina cycle using NH3-H2O mixture as a working fluid for the whole tri-generation system. A sensitive analysis of off-design conditions is carried out to study the effect of operational parameters on the system performances prior to optimizing its performance. The simulation show that the system is able to cover required heating and cooling demands. The optimization is applied considering the maximum exergy efficiency (scenario 1) and minimum total exergy destruction rate (scenario 2). The optimization results show that the maximum mean exergy efficiency in scenario 1 is achieved as 44.67% at the expense of 14.52% increase in the total exergy destruction rate in scenario 2. The minimum mean total exergy destruction rate in scenario 2 is calculated as 2980 kW at the expense of 8.32% decrease in the exergy efficiency in scenario 1.

description: Atlantic tarpon Megalops atlanticus (hereafter referred to as tarpon) is a popular and economically important inshore sport fish in Puerto Rico, and the pursuit of this species by local anglers and tourists contributes to the economy. This species is managed as a no-take fishery, which aims to preserve populations by catching and releasing fish that would otherwise be subjected to harvest and removal from the population. The approach assumes minimal mortality and/or reduced fitness of released fish, yet the process of angling can produce many sub-lethal side effects or direct mortality. In this study, charter angling for tarpon in the San Juan lagoon system in Puerto Rico was examined to determine post-release mortality.

description: Motivated by lower cost per ton-mile, U.S. Class I railroads have been replacing 263,000-pound GVW (gross vehicle weight) covered hopper cars (primarily used to haul grain) capable of handling 100 tons with 286,000-pound GVW cars that can handle 111 tons. Since the quality of track on shortline railroads is generally less than that of Class I railroads, it is likely that increasing use of heavy axle load (HAL) cars will have a greater impact on shortlines. If light density rail lines are not upgraded to handle HAL cars, the percentage of the grain car fleet that can move on shortlines will decline, possibly threatening the long-term viability of these railroads. If shortline railroads are abandoned it could have negative consequences for U.S. rural communities. The objectives are to document the shift from 263,000-pound rail cars to 286,000-pound cars by Class I railroads, and to measure the number of route miles and bridges that will require upgrading to handle the HAL rail cars (for a sample of Kansas shortlines). Other objectives include estimation of which branchlines are likely to be upgraded and which will likely be abandoned based on rate of return on investment analysis. The study also measured the road damage cost to state highways if upgrading to handle HAL cars does not occur and shortlines (or parts of shortlines) are abandoned. Analysis revealed that the total cost to upgrade 1,583 miles of mainline track and 1,352 bridges of five Kansas shortline railroads was estimated to be $308.7 million. None of the shortlines in the analysis can earn an adequate rate of return on upgrading track and bridge investment : given their current traffic densities and other characteristics. If the shortline railroads in the study are abandoned, the annual road damage costs in Kansas will increase by over $58 million.

description: It is known that beyond $2 \otimes 2$ and $2 \otimes 3$ dimensional quantum systems, Peres-Hordecki criterion is no longer sufficient as an entanglement detection criterion as there are entangled states with both positive and negative partial transpose (PPT and NPT). Further, it is also true that all PPT entangled states are bound entangled states. However, in the class of NPT states, there can exist bound entangled states as well as free entangled states. All free/useful/distillable entanglement is a part of the class of NPT entangled states. In this article, we ask the question that given an NPT entangled state in $3 \otimes3$ dimensional system as a resource, how much entanglement can we broadcast so that resource still remains NPT. We have chosen $3 \otimes 3$ system as a first step to understand broadcasting of NPT states in higher dimensional systems. In particular, we find out the range of broadcasting of NPT entanglement for Two parameter Class of States (TPCS) and Isotropic States (IS). Interestingly, as a derivative of this process we are also able to locate the existence of absolute PPT states (ABPPT) in $3 \otimes 3$ dimensional system. Here we implement the strategy of broadcasting through approximate cloning operations.

description: Abstract: A rigorous proof is presented of the boundedness of the entanglement entropy of a block of spins for the ground state of the one-dimensional quantum Ising model with sufficiently strong transverse field. This is proved by a refinement of the stochastic geometric arguments in the earlier work by Grimmett et al. (J Stat Phys 131:305–339, 2008). The proof utilises a transformation to a model of classical probability called the continuum random-cluster model. Our method of proof is fairly robust, and applies also to certain disordered systems.

description: The fundamental principles of electrodynamics allow an electron carrying both electric monopole (charge) and magnetic dipole (spin) but prohibit its magnetic counterpart. Recently it was predicted that the magnetic "monopoles" carrying emergent magnetic charges in spin ice systems can induce electric dipoles. The inspiring prediction offers a novel way to study magnetic monopole excitations and magnetoelectric coupling. However, no clear example has been identified up to now. Here, we report the experimental evidence for electric dipoles induced by magnetic monopoles in spin frustrated Tb2Ti2O7. The magnetic field applied to pyrochlore Tb2Ti2O7 along [111] direction, brings out a "3-in-1-out" magnetic monopole configuration, and then induces a subtle structural phase transition at Hc~2.3 T. The transition is evidenced by the non-linear phonon splitting under magnetic fields and the anomalous crystal-field excitations of Tb3+ ions. The observations consistently point to the displacement of the oxygen O" anions along [111] axis which gives rise to the formation of electric dipoles. The finding demonstrates that the scenario of magnetic monopole having both magnetic charge and electric dipole is realized in Tb2Ti2O7 and sheds light into the coupling between electricity and magnetism of magnetic monopoles in spin frustrated systems.

description: Interferometers offer multiple methods for studying microlensing events and determining the properties of the lenses. We investigate the study of microlensing events with optical interferometers, focusing on narrow-angle astrometry, visibility, and closure phase. After introducing the basics of microlensing and interferometry, we derive expressions for the signals in each of these three channels. For various forecasts of the instrumental performance, we discuss which method provides the best means of measuring the lens angular Einstein radius theta_E, a prerequisite for determining the lens mass. If the upcoming generation of large-aperture, AO-corrected long baseline interferometers (e.g. VLTI, Keck, OHANA) perform as well as expected, theta_E may be determined with signal-to-noise greater than 10 for all bright events. We estimate that roughly a dozen events per year will be sufficiciently bright and have long enough durations to allow the measurement of the lens mass and distance from the ground. We also consider the prospects for a VLTI survey of all bright lensing events using a Fisher matrix analysis, and find that even without individual masses, interesting constraints may be placed on the bulge mass function, although large numbers of events would be required.

description: We investigate the dynamics of a fluid of dipolar hard spheres in its liquid and glassy phase, with emphasis on the microscopic time or frequency regime. This system shows rather different glass transition scenarios related to its rich equilibrium behavior which ranges from a simple hard sphere fluid to a long range ferroelectric orientational order. In the liquid phase close to the ideal glass transition line and in the glassy regime a medium range orientational order occurs leading to a softening of an orientational mode. To investigate the role of this mode we use the molecular mode-coupling equations to calculate the spectra $ϕ_{lm}^{\prime \prime}(q,ω)$ and $χ_{lm}''(q,ω)$. In the center of mass spectra $ ϕ_{00}''(q,ω)$ and $χ_{00}''(q,ω)$ we found besides a high frequency peak at $ω_{hf}$ a peak at $ω_{op}$, about one decade below $ω_{hf}$. $ω_{op}$ has almost no $q$-dependence and exhibits an ``isotope'' effect $ω_{op}\propto I^{-1/2}$, with $I$ the moment of inertia. We give evidence that the existence of this peak is related to the occurrence of the medium ranged orientational order. It is shown that some of these feature also exist for schematic mode coupling models.

description: The main objective of NANORIGO (NANOtechnology RIsk GOvernance) is to develop and
 implement a transparent, transdisciplinary and science-based Risk Governance Framework
 (RGF) for managing possible nanotechnology risks regarding social, environmental and
 economic benefits. A new risk management approach is formed based on available
 high-quality data and advanced scientific tools developed for industry and regulators’
 decision-making, and on communication with all stakeholders (regulators, industries,
 politicians, the civil society). The RGF will use a life-cycle perspective and integrate available
 knowledge on ethical, social, environmental, and economic concerns into a user-friendly
 format that can be easily adapted and transferred into regulation for hazard, exposure and
 risk assessment and management of nanomaterials. It will consist of: (i) risk management
 strategies based on reinforced tools for guidance and decision-making developed for risk
 assessment, (ii) validated methodologies to identify potential hazard and exposure, and (iii) a
 web-based information and communication platform to facilitate access to good quality data
 and a clear risk understanding of stakeholders, and their valuable feedback. The NANORIGO
 work plan consists of 7 work packages covering all major risk governance aspects. Finally, a
 self-sustained European Risk Governance Council (ERGC) will be established and
 implemented by NANORIGO and all relevant stakeholders, and embedded in relevant
 international structures, in close cooperation with the International Risk Governance Center
 (IRGC). Case studies will demonstrate the sustainability of solutions and their consistent
 integration into regulatory applications under real conditions. For the first time, all
 stakeholders will be brought together under a common “umbrella” to share and integrate
 the most appropriate governance tools, frameworks and plans for future scientific and
 regulatory research and to foster consistency of management approaches in the EU and
 synergies internationally.
