description: Astronomers have proposed a number of mechanisms to produce supernova explosions. Although many of these mechanisms are now not considered primary engines behind supernovae, they do produce transients that will be observed by upcoming ground-based surveys and NASA satellites. Here we present the first radiation-hydrodynamics calculations of the spectra and light curves from three of these "failed" supernovae: supernovae with considerable fallback, accretion induced collapse of white dwarfs, and energetic helium flashes (also known as type .Ia supernovae).

Factors involved in the predator-prey relationship of rainbow trout (Salmo gairdneri Richardson) and redside shiners (Richardsonius balteatus (Richardson)) in Paul Lake, British Columbia
Creators: name: Crossman, Edwin John

description: The role of such factors as distribution and movements of predator (Salmo gairdneri) and prey (Richardsonius balteatus), the activity involved in predation and the contribution of prey to the diet of the predator were studied in order to answer where, when, how and to what extent trout preyed on shiners. Data for 1955 and 1956 are compared with data for years when trout alone inhabited the lake. Predation became significant in 1950, approximately five years after the introduction of the prey species and has increased steadily, especially in trout over 10 inches in length, since that time. Movements of shiners in Paul Lake are complex and tend to bring this species into contact with trout during July, August and September. At this time shiners constitute over 90 percent of the diet of trout over 14 inches in length and lesser volumes in smaller trout. Trout under six inches in length prey on shiners to an insignificant degree. In winter shiners form a negligible part of the diet of trout of all sizes. Movement patterns seem to indicate that these two species might be separated in winter, and as a result predation is almost nil. It is inferred from the study that predation by trout is not a control of the number of shiners in the lake. The growth rate of trout under eight inches in length is still depressed as a result of competition with shiners for food. The contribution of shiners through predation, to the diet of larger trout, appears to have elevated the growth rate of trout eight to twelve inches in length, somewhat above that for years when trout alone inhabited the lake. The casual rather than causative nature of this predator-prey interaction is compared with the more stylized, obligate relationships of predator and prey in models of predation in the published literature. This relationship between rainbow trout and redside shiners is also discussed as it applies to management of lakes in which "sport fish" and "coarse fish" exist together.

description: Material samples are a vital output of the scientific endeavour. They underpin research in the Earth, Space, and Environmental Sciences, and are a necessary component of ensuring the transparency and reproducibility of such research. While there has been a lot of discussion in recent years about the openness and FAIRness of data, code, methods, and so on, material samples have been much less under the spotlight. The lack of focus on material samples is in part due to them being unique as a research output, in the sense that they are inherently physical and thus they are mostly transported and managed by human beings rather than machines; it is rather more straightforward to archive and share both information about an output—and the output itself—for something that is already a digital object. However, it is for this reason that materials samples must be made more FAIR and treated as first-class citizens of Open Science. To do this, one needs to connect the physical and digital worlds. IGSN IDs enable these connections to be made. The IGSN ID is a globally unique and persistent identifier (PID) specifically for labelling material samples themselves (i.e., they are for neither images nor data about a sample). Functionally a Digital Object Identifier (DOI) registered under DataCite services, the IGSN ID can be applied to all types of material samples coming from any discipline. Not only can IGSN IDs be used to identify individual material samples that currently exist in a repository, museum, or otherwise, but they can also be registered At the aggregate level for sample collections. For the sites from which the samples are taken. For ephemeral samples. Importantly, in all cases, when registering an IGSN IDs, one must supply metadata in the DataCite Metadata Schema, as well as create landing pages that supply additional, disciplinary, user-focussed information about the collection, site, or (sub)sample. Hence, by registering a PID for a physical object, it is given a permanently resolvable URI to a findable and accessible digital footprint, and through the provision of rich metadata, enables its interoperability and reusability. Sharing of associated data is also possible within the metadata, and one may even include the potential for relocation of a sample itself for reuse. This presentation briefly introduced the IGSN ID and the partnership between DataCite and the IGSN e.V. to transfer the IGSN PID infrastructure under DataCite DOI services. It will mainly highlight practical use cases of IGSN IDs, including what is needed to include them in the sample workflow. It will also talk about efforts to better support IGSN IDs and sample metadata within the DataCite Metadata Schema.

description: Double neutron stars are one of the most promizing sources for terrestrial gravitational wave interferometers. For actual interferometers and their planned upgrades, the probability of having a signal present in the data is small, but as the sensitivity improves, the detection rate increases and the waveforms may start to overlap, creating a confusion background, ultimately limiting the capabilities of future detectors. The third generation Einstein Telescope, with an horizon of $z > 1$ and very low frequency ``seismic wall'' may be affected by such confusion noise. At a minimum, careful data analysis will be require to separate signals which will appear confused. This result should be borne in mind when designing highly advanced future instruments.

description: We measure the strength, frequency, and timescale of tidally triggered star formation at redshift z=0.08-0.38 in a spectroscopically complete sample of galaxy pairs drawn from the magnitude-limited redshift survey of 9,825 Smithsonian Hectospec Lensing Survey (SHELS) galaxies with R<20.3. To examine the evidence for tidal triggering, we identify a volume-limited sample of major (|ΔM_R|<1.75, corresponding to mass ratio >1/5) pair galaxies with $M_R < -20.8 in the redshift range z=0.08-0.31. The size and completeness of the spectroscopic survey allows us to focus on regions of low local density. The spectrophotometric calibration enables the use of the 4000 Ang break (D_n4000), the Hαspecific star formation rate (SSFR_{Hα}), and population models to characterize the galaxies. We show that D_n4000 is a useful population classification tool; it closely tracks the identification of emission line galaxies. The sample of major pair galaxies in regions of low local density with low D_n4000 demonstrates the expected anti-correlation between pair-wise projected separation and a set of star formation indicators explored in previous studies. We measure the frequency of triggered star formation by comparing the SSFR_{Hα} in the volume-limited sample in regions of low local density: 32 +/-7% of the major pair galaxies have SSFR_{Hα} at least double the median rate of the unpaired field galaxies. Comparison of stellar population models for pair and for unpaired field galaxies implies a timescale for triggered star formation of ~300-400 Myr.

Impurity-induced bound states in iron-based superconductors with s-wave cos(kx)cos(ky) pairing symmetry

description: Using both the self-consistent Bogoliubov-de Gennes formulation and non-self-consistent T-matrix approach, we perform a comprehensive investigation of the in-gap bound states induced by a localized single impurity in iron-based superconductors. We focus on studying signatures associated with the unconventional sign-changed s-wave pairing symmetry. For a non-magnetic impurity, we find that there are two in-gap bounds, symmetric with respect to zero energy, only in the sign changed s-wave pairing state, not in the sign-unchanged s-wave state, due to the existence of non-trivial Andreev bound states caused by the sign change. For a magnetic impurity, we find that due to the breakdown of the local time-reversal symmetry, there exist only bound state solutions (with orbital degeneracy) carrying one of the electron-spin polarizations around the impurity. As increasing the scattering strength, the system undergoes a quantum phase transition (level crossing) from a spin-unpolarized ground state to a spin-polarized one. While the results for the magnetic impurity are qualitatively similar in both the sign-changed and sign-unchanged s-wave superconducting states, the bound states in the first case are more robust and there is no $π$ phase shift of the SC gap near the impurity in the strong scattering regime.

Improved equations for eccentricity generation in hierarchical triple systems

description: In a series of papers, we developed a technique for estimating the inner eccentricity in hierarchical triple systems, with the inner orbit being initially circular. However, for certain combinations of the masses and the orbital elements, the secular part of the solution failed. In the present paper, we derive a new solution for the secular part of the inner eccentricity, which corrects the previous weakness. The derivation applies to hierarchical triple systems with coplanar and initially circular orbits. The new formula is tested numerically by integrating the full equations of motion for systems with mass ratios from 10^(-3) to 10^(3). We also present more numerical results for short term eccentricity evolution, in order to get a better picture of the behaviour of the inner eccentricity.

description: Quark Gluon Plasma transport coefficients for heavy quarks and quark-antiquark pairs are computed through an extension of the results obtained for a hot QED plasma by describing the heavy-quark propagation in the eikonal approximation and by weighting the gauge field configurations with the Hard Thermal Loop effective action. It is shown that such a model allows to correctly reproduce, at leading logarithmic accuracy, the results obtained by other independent approaches. The results are then inserted into a relativistic Langevin equation allowing to follow the evolution of the heavy-quark momentum spectra. Our numerical findings are also compared with the ones obtained in a strongly-coupled scenario, namely with the transport coefficients predicted (though with some limitations and ambiguities) by the AdS/CFT correspondence.

description: Loschmidt echo (LE) is a measure of reversibility and sensitivity to perturbations of quantum evolutions. For weak perturbations its decay rate is given by the width of the local density of states (LDOS). When the perturbation is strong enough, it has been shown in chaotic systems that its decay is dictated by the classical Lyapunov exponent. However, several recent studies have shown an unexpected non-uniform decay rate as a function of the perturbation strength instead of that Lyapunov decay. Here we study the systematic behavior of this regime in perturbed cat maps. We show that some perturbations produce coherent oscillations in the width of LDOS that imprint clear signals of the perturbation in LE decay. We also show that if the perturbation acts in a small region of phase space (local perturbation) the effect is magnified and the decay is given by the width of the LDOS.

While our half-lattice results are formulated in terms of matrix-valued Weyl-Titchmarsh functions, our full-lattice results involve the diagonal and main off-diagonal Green's matrices. We also develop the basics of Weyl-Titchmarsh theory for CMV operators with matrix-valued Verblunsky coefficients as this is of independent interest and an essential ingredient in proving the corresponding Borg-Marchenko-type uniqueness theorems.

description: We introduce new formulations of aperiodicity and cofinality for finitely aligned higher-rank graphs Λ, and prove that C*(Λ) is simple if and only if Λis aperiodic and cofinal. The main advantage of our versions of aperiodicity and cofinality over existing ones is that ours are stated in terms of finite paths. To prove our main result, we first characterise each of aperiodicity and cofinality of Λin terms of the ideal structure of C*(Λ). In an appendix we show how our new cofinality condition simplifies in a number of special cases which have been treated previously in the literature; even in these settings, our results are new.

description: This brief highlights the need to prepare pre-service teachers (PSTs) to effectively teach computer science (CS) at the K–6 level. In response to Alabama’s Computer Science Bill (Act 2019-389), Auburn University developed a CS education course for PSTs in early childhood, elementary, and special education programs. Survey data from nearly 200 PSTs show that while over 84% support the state policy, many initially lacked confidence in their CS knowledge and teaching ability. However, after completing the required course, PSTs reported significant gains in both knowledge and confidence, and a more positive perception of CS education. These findings emphasize the importance of integrating CS training into teacher preparation programs and the need for continued policy support to ensure all students benefit from early exposure to CS.

description: In response to the call for a science of science policy, we discuss the contribution of indicators at the macro-level of nations from a scientometric perspective. In addition to global trends such as the rise of China, one can relate percentages of world share of publications to government expenditure in academic research. The marginal costs of improving one's share are increasing over time. Countries differ considerably in terms of the efficiency of turning (financial) input into bibliometrically measurable output. Both funding schemes and disciplinary portfolios differ among countries. A price per paper can nevertheless be estimated. The percentages of GDP spent on academic research in different nations are significantly correlated to historical contingencies such as the percentage of researchers in the population. The institutional dynamics make strategic objectives such as the Lisbon objective of the EU--that is, spending 3% of GDP for R&D in 2010--unrealistic.

description: We examined doping effect of 3d transition metal elements (TM: Cr, Mn, Co, Ni, and Cu) at the Fe site of a quaternary fluoroarsenide CaFeAsF, an analogue of 1111-type parent compound LaFeAsO. The anomaly at ~120 K observed in resistivity (rho) vs. temperature (T) plot for the parent compound is suppressed by the doping of each TM element. Furthermore, Co- and Ni-doping (CaFe1-xTMxAsF, TM = Co, Ni) induces superconductivity with a transition temperature maximized at the nominal x = 0.10 for Co (22 K) and at x = 0.05 for Ni (12 K). These optimal doping levels may be understood by considering that Ni2+(3d8) adds double electrons to the FeAs layers compared with Co2+ (3d7). Increased x for Co or Ni breaks the superconductivity while metallic nature drho/dT > 0 is still kept. These observations indicate that Co and Ni work as electron donors. In contrast, neither of Cr, Mn nor Cu-doping induce superconductivity, yielding drho/dT < 0 in the below the rho-T anomaly temperature, indicating that these transition metal ions act as scattering centers. The two different behavior of TM replacing the Fe site is discussed in relation to the changes in the lattice constants with the doping.

The components of predation as revealed by a study of predation by small mammals of Neodiprion sertifer (Geoff.)
Creators: name: Holling, Crawford Stanley
Publisher: name: University of British Columbia
Year: 2012

description: The basic components and subsidiary factors comprising predation have been demonstrated in field and laboratory studies that analyzed the predation by small mammals of the European pine sawfly, Neodiprion sertifer (Geoff.). Predation was restricted to the cocoon stage of the insect and only three species of small mammals were important predators -- Sorex cinereus cinereus Kerr, Blarina brevicauda talpoides Gapper, and Peromyscus maniculatus bairdii Hoy and Kennicott. The characteristics of the prey and of the field conditions were so simple that prey density and predator density were the only variables affecting predation. There were two basic responses to changes in prey density: the functional response, where the number of cocoons consumed per predator changed and the numerical response, where the density of predators changed. These responses differed for the three different predators. When the two basic responses were combined to reveal the relation between per cent predation and prey density, predation increased initially with increase in prey density (concurrent density dependence) and thereafter decreased (inverse density dependence). The forms of these peaked predation curves was different for each species of predator, for they reached different maxima and peaked at different prey densities. The functional and numerical responses are the basic components of predation. Laboratory experiments, however, showed that subsidiary factors can exert an effect through these responses. Prey characteristics, by altering the strength of stimulus from prey, can change both the functional and numerical responses. Similarly, increase in the number or palatability of alternate foods can decrease the functional response and increase the numerical response. A hypothetical predator - prey model showed that under certain conditions the peaked type of predation can regulate the numbers of a prey and can damp oscillations of prey numbers. The scheme of predation revealed in this study can explain all types of predation and types of parasitism as well. It seems, however, that there are four major types of predation conceivable, each type having different functional and numerical responses.

Un gruppo di ricercatori polacchi e inglesi ha dimostrato che, stando ai calcoli teorici, un sistema che subisce accelerazioni sufficientemente elevate potrebbe misurare tempi di decadimento variabili per alcune particelle elementari. Questo metterebbe in crisi la possibilità di misurare il reale scorrere del tempo
Strong correlation effects in single-wall carbon nanotubes
Creators: name: Carr, Sam T.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We present an overview of strong correlations in single-wall carbon nanotubes, and an introduction to the techniques used to study them theoretically. We concentrate on zigzag nanotubes, although universality dictates that much ofthe theory can also be applied to armchair or chiral nanotubes. We show how interaction effects lead to exotic low energy properties and discuss future directions for studies on correlation effects in nanotubes.

description: The sociological domain is different from the psychological one insofar as meaning can be communicated at the supra-individual level (Schutz, 1932; Luhmann, 1984). The computation of anticipatory systems enables us to distinguish between these domains in terms of weakly and strongly anticipatory systems with a structural coupling between them (Maturana, 1978). Anticipatory systems have been defined as systems which entertain models of themselves (Rosen, 1985). The model provides meaning to the modeled system from the perspective of hindsight, that is, by advancing along the time axis towards possible future states. Strongly anticipatory systems construct their own future states (Dubois, 1998a and b). The dynamics of weak and strong anticipations can be simulated as incursion and hyper-incursion, respectively. Hyper-incursion generates "horizons of meaning" (Husserl, 1929) among which choices have to be made by incursive agency.

Rigorous proof of slightly nonlinear Jeans instability in the expanding Newtonian universe

description: Due to the nonlinearity of the Euler{Poisson equations, it is possible that the nonlinear Jeans instability may lead to a faster density growing rate than the rate in the standard theory of linearized Jeans instability, which motivates us to study the nonlinear Jeans instability. The aim of this article is to develop a method proving the Jeans instability for slightly nonlinear Euler-Poisson equations in the expanding Newtonian universe. The standard proofs of the Jeans instability rely on the Fourier analysis. However, it is difficult to generalize Fourier method to a nonlinear setting, and thus there is no result in the nonlinear analysis of Jeans instability. We firstly develop a non-Fourier-based method to reprove the linearized Jeans instability in the expanding Newtonian universe. Secondly, we generalize this idea to a slightly nonlinear case. This method relies on the Cauchy problem of the Fuchsian system due to the recent developments of this system in mathematics. The fully nonlinear Jeans instability for the Euler-Poisson and Einstein-Euler equations are in progress.
