description: We reinvestigate effects of neutrino oscillations on the production of 7Li and 11B in core-collapse supernovae (SNe). During the propagation of neutrinos from the proto-neutron star, their flavors change and the neutrino reaction rates for spallation of 12C and 4He are affected. In this work corrected neutrino spallation cross sections for 4He and 12C are adopted. Initial abundances involving heavy s-nuclei and other physical conditions are derived in a new calculation of the SN 1987A progenitor in which effects of the progenitor metallicity are included. A dependence of the SN nucleosynthesis and final yields of 7Li and 11B on the neutrino mass hierarchy are shown in several stellar locations. In the normal hierarchy case, the charged current reaction rates of electron neutrinos are enhanced, and yields of proton-rich nuclei, along with 7Be and 11C, are increased. In the inverted hierarchy case, the charged current reaction rates of electron antineutrinos are enhanced, and yields of neutron-rich nuclei, along with 7Li and 11B, are increased. We find that variation of the metallicity modifies the yields of 7Li, 7Be, 11B, and 11C. This effect is caused by changes in the neutron abundance during SN nucleosynthesis. Therefore, accurate calculations of Li and B production in SNe should take into account the metallicity of progenitor stars.

The Speaker's Need for Asking Questions
Creators: name: Athanasiadou, Angeliki
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1993

description: Research on questions has shown that in the majοrity of cases the meaning of questions has been linked with the speaker's request for information. So, in many contexts one asks a question in order to elicit an informative answer. This fact may point tο the prototyρical character of information questions and all the other types have a peripheral status. If the prototypical type is 'request for information', what is the status of all the other tyρes? How do they relate to the prototype and to each other? And why should questions be approached in terms of networks of relationships? The purpose of this paper is to construct a network of the category of questions. The structure of this category is effected through the examination of the various speech events. Depending οn the knowledge, the intentions, the beliefs and the needs of the speakers, conceptual entities are identified and they are structured according to differences in meaning. The links between the various types of questίons will be pointed out through paths of meaning extension and the conceptual processes exhibited in the speaker’s need of asking questions will be analysed.

description: No abstracts are to be cited without prior reference to the author.In the Barents Sea, bottom fish species are harvested by both bottom trawls and longlines. Despite the similar main target fish species for these gears (cod, haddock, halibut) they differ in selectivity. The species and length composition of catches by trawls and longlines is dissimilar. Because of this, fisheries by bottom trawl and longline have a diverse impact on separate fish stocks and the whole Barents Sea fish fauna. Some fish stocks of the Barents Sea are difficult to access by longlining although they are successfully fished by trawling; in contrast, longlines can be used to target fish species that are present in trawls as a bycatch. In fishery both gears intensively affect the bottom biotope and the biocenoses having formed there. A trawl is an active gear towed at the bottom, whereas a longline lies passively on the ground; therefore a trawl undoubtedly has a greater negative impact on bottom biocenoses. However, unlike a longline, a trawl does not have the disadvantage of catching birds. The paper gives a comparative analysis of the impact of bottom trawling and longlining in the Barents Sea on separate elements of its ecosystem. The effect of those gears on bottom biocenoses, fish stocks, and bird communities was analysed.

description: One of the main challenges of deep learning tools is their inability to capture model uncertainty. While Bayesian deep learning can be used to tackle the problem, Bayesian neural networks often require more time and computational power to train than deterministic networks. Our work explores whether fully Bayesian networks are needed to successfully capture model uncertainty. We vary the number and position of Bayesian layers in a network and compare their performance on active learning with the MNIST dataset. We found that we can fully capture the model uncertainty by using only a few Bayesian layers near the output of the network, combining the advantages of deterministic and Bayesian networks.
Auger Recombination in Semiconductor Quantum Wells

description: The principal mechanisms of Auger recombination of nonequilibrium carriers in semiconductor heterostructures with quantum wells are investigated. It is shown for the first time that there exist three fundamentally different Auger recombination mechanisms of (i) thresholdless, (ii) quasi-threshold, and (iii) threshold types. The rate of the thresholdless Auger process depends on temperature only slightly. The rate of the quasi-threshold Auger process depends on temperature exponentially. However, its threshold energy essentially varies with quantum well width and is close to zero for narrow quantum wells. It is shown that the thresholdless and the quasi-threshold Auger processes dominate in narrow quantum wells, while the threshold and the quasi-threshold processes prevail in wide quantum wells. The limiting case of a three-dimensional (3D)Auger process is reached for infinitely wide quantum wells. The critical quantum well width is found at which the quasi-threshold and threshold Auger processes merge into a single 3D Auger process. Also studied is phonon-assisted Auger recombination in quantum wells. It is shown that for narrow quantum wells the act of phonon emission becomes resonant, which in turn increases substantially the coefficient of phonon-assisted Auger recombination. Conditions are found under which the direct Auger process dominates over the phonon-assisted Auger recombination at various temperatures and quantum well widths.

description: Here we present a novel approach to control magnetic interactions in atomic-scale nanowires. Our ab initio calculations demonstrate the possibility to tune magnetic properties of Fe nanowires formed on vicinal Cu surfaces. Both intrawire and interwire magnetic exchange parameters are extracted from DFT calculations. This study suggests that the effective interwire magnetic exchange parameters exhibit Ruderman--Kittel--Kasuya--Yosida-like (RKKY) oscillations as a function of Fe interwire separation. The choice of vicinal Cu surface offers possibilities for controlling the magnetic coupling. Furthermore, an anisotropic Heisenberg model was used in Monte Carlo simulations to examine the stability of these magnetic configurations at finite temperature. The predicted critical temperatures of the Fe nanowires on Cu(422) and Cu(533) surfaces are well-above room temperature.

description: It is shown that if a generalized definition of gauge invariance is used, gauge invariant effective stress-energy tensors for gravitational waves and other gravitational perturbations can be defined in a much larger variety of circumstances than has previously been possible. In particular it is no longer necessary to average the stress-energy tensor over a region of spacetime which is larger in scale than the wavelengths of the waves and it is no longer necessary to restrict attention to high frequency gravitational waves.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Long‐term dynamics of spring‐spawning herring and northeast Arctic cod recruitment is reported to be in line with the several main Arctic climatic indices, such as Arctic air surface temperature (Arctic dT) and mean temperature of 200‐m water column along the “Kola Meridian” section (Kola meridian dT). Variation in the herring stock recruitment is shown to be correlate with the Arctic dT and Kola meridian dT dynamics, although the cod recruitment follows these indices with a 8‐ to 10year lag. The Russian Arctic and Antarctic Research Institute (AARI) reports that for the last 100 years Arctic dT has displayed some 60‐year regular fluctuations with maxima in the 1940s and 2000s, and suggests a descending trend in the Arctic dT in the most recent 10–20 years. Thus, in the next 10 years, commercial herring stocks are likely to decrease, whereas the cod commercial stocks are likely to increase. The walleye pollock fishable biomass in the Bering Sea for the past 35 years was shown to vary in line with the PDO (Pacific Decadal Oscillation), the main temperature index of the North Pacific. In particular, higher values of the walleye pollock fishable biomass were attributed to positive PDO anomalies, whereas the lower values of biomass were characteristic of negative PDO anomalies. Analysing both PDO and solar activity dynamics for the past 100 years, a negative PDO trend in the North Pacific may be forecast. Therefore, a gradual decrease in the fishable walleye pollock biomass is likely to take place in the next 10–20 years in the Bering Sea.

description: We present a formalism to obtain equilibrium configurations of uniformly rotating fluid in the second post-Newtonian approximation of general relativity. In our formalism, we need to solve 29 Poisson equations, but their source terms decrease rapidly enough at the external region of the matter(i.e., at worst $O(r^{-4})$). Hence these Poisson equations can be solved accurately as the boundary value problem using standard numerical methods.This formalism will be useful to obtain nonaxisymmetric uniformly rotating equilibrium configurations such as synchronized binary neutron stars just before merging and the Jacobi ellipsoid.

description: The physics of low-energy quasi-particle excitations in disordered d-wave superconductors is a subject of ongoing intensive research. Over the last decade, a variety of conceptually and methodologically different approaches to the problem have been developed. Unfortunately, many of these theories contradict each other, and the current literature displays a lack of consensus on even the most basic physical observables. Adopting a symmetry-oriented approach, the present paper attempts to identify the origin of the disagreement between various previous approaches, and to develop a coherent theoretical description of the different low-energy regimes realized in weakly disordered d-wave superconductors. We show that, depending on the presence or absence of time-reversal invariance and the microscopic nature of the impurities, the system falls into one of four different symmetry classes. By employing a field-theoretical formalism, we derive effective descriptions of these universal regimes as descendants of a common parent field theory of Wess-Zumino-Novikov-Witten type. As well as describing the properties of each universal regime, we analyse a number of physically relevant crossover scenarios, and discuss reasons for the disagreement between previous results. We also touch upon other aspects of the phenomenology of the d-wave superconductor such as quasi-particle localization properties, the spin quantum Hall effect, and the quasi-particle physics of the disordered vortex lattice.

Modelling the Process of Literary Translation; Testing the Model to Destruction
Creators: name: Bell, Roger
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1993

description: Although, in recent years, substantial advances have been made in translation theory - particularly in the modelling of the process itself - it still seems to be axiomatic that the literary text contains language which is so dramatically different from 'ordinary language' and, therefore, so inherently difficult that it is the acid test of the 'good translator'. At its most extreme, this attitude resolves itself into the assertion that the differences and dίfficulties are so great that such texts cannot be translated at all. Given that there are in existence texts which purport to be translatίons of literary texts, the question arίses 'What are these texts?' (i.e. how can such texts be distinguished from other texts? ) and, linked to that, 'How are they produced?' (i.e. how can we model the process?) This paper charts the progress of modifying an existing general model of translation to make it suitable for the descriptiοn and explanation of the process of literary translation. In essence, this involves an approach which assumes that the literary text should be treated in the same way as the non-literary; the source text should be subjected to a rigorοus stylίstic analysis as a major part of the reading stage and, once translated, treated in the same way as any other sample text in the same genre in the target language. The implementation of this proposal requires, it is argued, additional sophistication to be built into the existing process model; particularly, though not exclusively, at the stylistic/pragmatic stages of analysis and synthesis. The resultant model will (ideally) demonstrate how current insights from linguistics can illuminate the process of literary translation and proνide linguists, critics and translators with a common language for sharing their expertise and experience.

We consider the effects of electronic disorder and of a strongly anisotropic tunneling matrix element, and show that in real materials they will likely obscure the ~1/r asymptotic tail in the zero-bias tunneling conductance expected from the straightforward semiclassical analysis. We also give a prediction for the tunneling conductance anisotropy around the vortex core and establish a connection to the structure of the tunneling matrix element.

Linguistic Information and Processing Components: What is modular?
Creators: name: Danks, Joseph H.
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1993

description: Discourse and texts contain many different types of information for the comprehender tο use in constructing a representation of what the speaker or writer intended -- auditory/visual, phonological/orthographic, lexical, syntactic, semantic, pragmatic, and propositional content. How does the comprehender (listener or reader) use these different types of information tο construct a representation of what the discourse or text means? Α common assumption, in particular as represented in the modularity hypothesis, is that for each type of information there is a cognitive processing component dedicated to processing that type of information. An alternative analysis assumes that processing components are specified in functional terms, that is, in terms of the requirements of the processing tasks to be completed by the comprehender. Processing components are needed to perceive speech sounds or print, tο access information about words, tο determine sentence meanings, and to construct a representation of what the discourse οr text means. These components may use more than one type of information from the linguistic signal to complete their respective tasks. Behavioral data from reading comprehension tasks support breaking the one- to-one mapping between types of linguistic information and cognitive processing components. The same linguistic information is encoded differently across languages and aΙters how it is processed, thus supporting the separation of linguistic information types from processing components.

description: No abstracts are to be cited without prior reference to the author.Population connectivity (i.e. exchange of individuals) is an essential characteristic of species, which affects their resilience to external pressures, including climate change and anthropogenic impacts. Spatial structuring and population differentiation of key species in the diverse continental shelf, slope, and open ocean environments across the North Atlantic are critical foundations for ecosystem approaches to fishery management. Use of a standard measure of connectivity, such as DNA sequence divergence of the mitochondrial cytochrome oxidase I (COI) barcode gene, allows comparisons of patterns of connectivity among species and over time. In this study, patterns and pathways of gene flow are characterized and compared for ecologically important North Atlantic species of copepods (e.g. Calanus, Pseudocalanus, Clausocalanus) and euphausiids (e.g. Meganyctiphanes norvegica, Stylocheiron spp.) based on COI sequence variation. Results are discussed for the effects of life history and behaviour, biogeographical distribution, impacts of past climate effects (e.g. bottlenecks with glaciation), and possible responses to recent environmental changes. Future research directions include exploring conceptual and statistical approaches to using population connectivity in the context of ecosystem approaches to fishery management.

We do this by solving a tangentially-smoothed version of Euler's equations in Lagrangian coordinates which satisfies uniform energy estimates as the smoothing parameter goes to zero. The main technical tools are delicate energy estimates and optimal elliptic estimates in terms of boundary regularity, for the Dirichlet problem and Green's function.

description: We present an experimental study of segregation of granular matter in a quasi-two dimensional silo emptying out of an orifice. Size separation is observed when multi-sized particles are used with the larger particles found in the center of the silo in the region of fastest flow. We use imaging to study the flow inside the silo and quantitatively measure the concentration profiles of bi-disperse beads as a function of position and time. The angle of the surface is given by the angle of repose of the particles, and the flow occurs in a few layers only near the top of this inclined surface. The flowing region becomes deeper near the center of the silo and is confined to a parabolic region centered at the orifice which is approximately described by the kinematic model. The experimental evidence suggests that the segregation occurs on the surface and not in the flow deep inside the silo where velocity gradients also are present. We report the time development of the concentrations of the bi-disperse particles as a function of size ratios, flow rate, and the ratio of initial mixture. The qualitative aspects of the observed phenomena may be explained by a void filling model of segregation.

description: We show that static sources coupled to a massless scalar field in Schwarzschild spacetime give rise to emission and absorption of zero-energy particles due to the presence of Hawking radiation. This is in complete analogy with the description of the bremsstrahlung by a uniformly accelerated charge from the coaccelerated observers' point of view. The response rate of the source is found to coincide with that in Minkowski spacetime as a function of its proper acceleration. This result may be viewed as restoration of the equivalence principle by the Hawking effect.

description: In a novel approach to quantum dynamics, we apply the tools of recurrence network analysis to the dynamics of the quantum mechanical expectation values of observables. We construct and analyse $ε$-recurrence networks from the time-series data of the mean photon number in a model tripartite quantum system governed by a nonlinear Hamiltonian. The role played by the intensity-dependent field-atom coupling in the dynamics is investigated. Interesting features emerge as a function of a parameter characterising this intensity-dependent coupling in both the short-time and the long-time dynamics. In particular, we examine the manner in which standard measures of network theory such as the average path length, the link density and the clustering coefficient depend on this parameter.

description: In this paper we present and verify the non-linear simulation of an aspherical adaptive lens based on a piezo-glass sandwich membrane with combined bending and buckling actuation. To predict the full non-linear piezoelectric behavior, we measured the non-linear charge coefficient, hysteresis and creep effects of the piezo material and inserted them into the FEM model using a virtual electric field. We further included and discussed the fabrication parameters -- glue layers and thermal stress -- and their variations. To verify our simulations, we fabricated and measured a set of lenses with different geometries, where we found good agreement and show that their qualitative behavior is also well described by a simple analytical model. We finally discuss the effects of the geometry on the electric response and find, e.g., an increased focal power range from $\pm 4.5$ to $\pm 9\, \mathrm{m}^{-1}$ when changing the aperture from $14$ to $10\, \mathrm{mm}$.

On the so Called "Agentive" Nominals in English and their Counterparts in Mod Greek

description: The term "Agentive" which is used tο cover such derived nomimal as builder, maker, diver and their Modern Greek counterparts ktistis, kataskevastis, δitis is just a misnomer. Α more promising approach tο the formation of the nominals in question should involve specific reference tο the Argument Structure of the verb from which these nominals are derived: οnly external arguments can be matched with the _er/_tis affixes. However, in the case of English nominals, but definitely not in the case of their counterparts in Mod Greek, it is possible το externalize an internal argument in the Lexicon and thus form derived nominals that refer tο a Theme (formerly internal) argument, e.g. best seller, poetry reader, which refer to a book that is sold and a book that is read, respectively rather than to someone who sells or reads books, that is in English _er nominals may not refer tο the entity that carries οut the action expressed by the verb. This may reflect a basic difference between English and Mod Greek: the former language has more argument externalization possibilities than the latter language either via syntax or through the lexicon.

description: We investigate the response of multi-walled carbon nanotubes to mechanical strain applied with an Atomic Force Microscope (AFM) probe. We find that in some samples, changes in the contact resistance dominate the measured resistance change. In others, strain large enough to fracture the tube can be applied without a significant change in the contact resistance. In this case we observe that enough force is applied to break the tube without any change in resistance until the tube fails. We have also manipulated the ends of the broken tube back in contact with each other, re-establishing a finite resistance. We observe that in this broken configuration the resistance of the sample is tunable to values 15-350 kW greater than prior to breaking.

description: No abstracts are to be cited without prior reference to the author.Recent studies suggest that climate variability may act in the marine environment from the bottomup, via primary and secondary productivities or from the top‐down through controls on key predator populations, potentially inducing substantial, wide‐ranging, and complex responses both within and among communities. Given the potential profound and varied effects of climate variability on the biomass, age structure, and growth rates of fish in the Northeast Atlantic ecosystems (namely, within the Azores region, where commercial fisheries constitute a strong economic regional revenue), a detailed description and understanding of climate patterns, processes, and impacts became critical for developing better fish management strategies in the region. In this study we use 15 years of demersal fish cruise surveys and relate Pagellus bogaraveo (a commercial fish species of the Azores) abundance indices with North Atlantic Oscillation (NAO) seasonal indices for the same period of time. Preliminary results are encouraging and demonstrate positive and significant correlation between the fish abundance and the atmospheric indices. This work raised new scientific questions and challenges by integrating for the first time in the Azores, expertise from scientists from different fields (physical/biological oceanographers and fishery biologists), in an attempt to describe, explain, and establish climate–ecosystem relationships for the region.

description: We report improved masses, radii, and densities for four planets in two bright M-dwarf systems, K2-3 and GJ3470, derived from a combination of new radial velocity and transit observations. Supplementing K2 photometry with follow-up Spitzer transit observations refined the transit ephemerides of K2-3 b, c, and d by over a factor of 10. We analyze ground-based photometry from the Evryscope and Fairborn Observatory to determine the characteristic stellar activity timescales for our Gaussian Process fit, including the stellar rotation period and activity region decay timescale. The stellar rotation signals for both stars are evident in the radial velocity data and are included in our fit using a Gaussian process trained on the photometry. We find the masses of K2-3 b, K2-3 c and GJ3470 b to be 6.48$^{+0.99}_{-0.93}$, 2.14$^{+1.08}_{-1.04}$, and 12.58$^{+1.31}_{-1.28}$ M$_\oplus$ respectively. K2-3 d was not significantly detected and has a 3-$σ$ upper limit of 2.80 M$_\oplus$. These two systems are training cases for future TESS systems; due to the low planet densities ($ρ$ $

description: It has recently been suggested that the Standard Model Higgs boson could act as the inflaton while minimally coupled to gravity - given that the gravity sector is extended with an $αR^2$ term and the underlying theory of gravity is of Palatini, rather than metric, type. In this paper, we revisit the idea and correct some shortcomings in earlier studies. We find that in this setup the Higgs can indeed act as the inflaton and that the tree-level predictions of the model for the spectral index and the tensor-to-scalar ratio are $n_s\simeq 0.941$, $r\simeq 0.3/(1+10^{-8}α)$, respectively, for a typical number of e-folds, $N=50$, between horizon exit of the pivot scale $k=0.05\, {\rm Mpc}^{-1}$ and the end of inflation. Even though the tensor-to-scalar ratio is suppressed compared to the usual minimally coupled case and can be made compatible with data for large enough $α$, the result for $n_s$ is in severe tension with the Planck results. We briefly discuss extensions of the model.

description: No abstracts are to be cited without prior reference to the author.Analysis of oscillations in meteorological and oceanographic parameters in the Northwest Atlantic (NWA) in the last 50 years revealed three periods in their development. The first one lasted from the end of the 1950s to the end of the 1970s–beginning of 1980s; the second one from beginning of the 1980s to the mid‐1990s and the third one from the mid‐1990s to today, which is to be completed soon. These periods and their sequence appear in the many‐years trend of the North Atlantic Oscillation (NAO) index, in temperature variations at the surface and near bottom on the NWA shelf, in the volume of the cold intermediate layer, in the variability of ice‐covered areas, and in shifts of hydrological fronts along the meridian. These variations in environmental conditions are well‐coordinated with oscillations in the abundance and stocks of generations in some economically important fish of NWA (Greenland halibut, redfish, cod, thorny skate, Atlantic mackerel, herring). Here we present diagrams of water temperature changes, NAO indices, the dynamics of the localization of oceanic fronts, and oscillations in fish abundance.
