description: We study the problem of critical adsorption of piecewise directed random walks on a boundary of fractal lattices that belong to the Sierpinski gasket family. By applying the exact real space renormalization group method, we calculate the crossover exponent $ϕ$, associated with the number of adsorbed steps, for the complete fractal family. We demonstrate that our results are very close to the results obtained for ordinary self-avoiding walk, and discuss the asymptotic behaviour of $ϕ$ at the fractal to Euclidean lattice crossover.

description: We propose a measurement set-up for detecting quantum noise over a wide frequency range using inelastic transitions in a tunable two-level system as a detector. The frequency-resolving detector consists of a double quantum dot which is capacitively coupled to the leads of a nearby mesoscopic conductor. The inelastic current through the double quantum dot is calculated in response to equilibrium and non-equilibrium current fluctuations in the nearby conductor, including vacuum fluctuations at very low temperatures. As a specific example, the fluctuations across a quantum point contact are discussed.

description: We analyze the decay processes of ${\bf B}_c \to {\bf B}_n M$ with the $SU(3)_F$ flavor symmetry and spin-dependent amplitudes, where ${\bf B}_c({\bf B}_n)$ and $M$ are the anti-triplet charmed (octet) baryon and nonet meson states, respectively. In the $SU(3)_F$ approach, it is the first time that the decay rates and up-down asymmetries are fully and systematically studied without neglecting the ${\cal O}(\overline{15})$ contributions of the color anti-symmetric parts in the effective Hamiltonian. Our results of the up-down asymmetries based on $SU(3)_F$ are quite different from the previous theoretical values in the literature. In particular, we find that the up-down symmetry of $ α(Λ_c^+\to Ξ^0 K^+)_{SU(3)} = 0.94^{+0.06}_{-0.11}$, which is consistent with the recent experimental data of $0.77\pm0.78$ by the BESIII Collaboration, but predicted to be zero in the literature. We also examine the $K_S^0-K_L^0$ asymmetries between the decays of ${\bf B}_c \to {\bf B}_n K_S^0$ and ${\bf B}_c \to {\bf B}_n K_L^0$ with both Cabibbo-allowed and doubly Cabibbo-suppressed transitions.

description: No abstracts are to be cited without prior reference to the author.Crustaceans are an important resource in the Azores. The crab Cancer bellianus is almost considered a virgin stock, being punctually captured during spring and summer on two islands. However, effort has been made by fishers to develop a targeted commercial fishery. Information published up till now has been scarce and has been related to certain aspects of the biology and abundance of the species. This work aimed to characterize the actual fishery, summarize key biological information, assess the potential yield of the resource, and discuss management issues before the development of the fishery. The crabs were caught with traps at depths between 100 and 600 m. Traps were baited using various species, including sardine (Sardina pilchardus), congro (Conger conger), and dolphinfish (Coryphaena hippurus). In all, 5345 crabs (1423 males and 3737 females) were sampled. Sizes ranged from 7 to 290 mm carapace width (CW). The highest abundance occurred at depths from 300 to 500 m. Females were relatively more abundant at depths of 300400 m and males relatively more abundant at depths of 500–600 m. Only two ovigerous females were caught during September and October. The distribution area of the resource includes coastal areas and seamounts around the Azores EEZ. The species habitat was mapped and potential fishing areas around the EEZ highlighted. The estimated potential yield of the resource suggests that it would not support an industrial fishery. Thus, artisanal fisheries on a community‐based management system around the islands are suggested and discussed.
Universal scaling of the self-field critical current in superconductors: from sub-nanometre to millimetre size

description: Universal scaling behaviour in superconductors has significantly elucidated fluctuation and phase transition phenomena in these materials. However, universal behaviour for the most practical property, the critical current, was not contemplated because prevailing models invoke nucleation and migration of flux vortices. Such migration depends critically on pinning, and the detailed microstructure naturally differs from one material to another, even within a single material. Through microstructural engineering there have been ongoing improvements in the field-dependent critical current, thus illustrating its nonuniversal behaviour. But here we demonstrate the universal size scaling of the self-field critical current for any superconductor, of any symmetry, geometry or band multiplicity. Key to our analysis is the huge range of sample dimensions, from single-atomic-layer to mm-scale. These have widely variable microstructure with transition temperatures ranging from 1.2 K to the current record, 203 K. In all cases the critical current is governed by a fundamental surface current density limit given by the relevant critical field divided by the penetration depth.

description: No abstracts are to be cited without prior reference to the author.The systematic mapping of the marine benthic habitat and its biological communities requires very specialized oceanographic instrumentation. The use of remotely operated vehicle (ROV) video images should provided high‐resolution megafaunal abundance and biodiversity information. In March 2011, two gas pipelines were inspected with ROVs in the Strait of Gibraltar area. We had the opportunity of participate in the survey as observers and the online video footage shows high coral colonization of the gas pipes. So we asked the gas company for the video files because we considered that it could give very useful information about the Strait of Gibraltar sea ground and some idea about its habitats. Although the main objective of the survey was inspection of the two gas pipelines that link the Spanish and Moroccan coasts, this study presents another approach for seabed habitat mapping based on an integrated analysis of the video recordings from three cameras on the ROV performed in the Strait of Gibraltar. These pipes should be considered as 45km transects which should be analysed related to their environmental features. The habitats should be primarily distinguished on several bases such as biological associations, water depth, sediment type, current strength, and also north–south axis. Another approach that may be taken into account is local‐scale anthropogenic disturbance such as lost fishing gear and garbage that appears all over the gas pipes, which act as a barrier on the marine bottom. This study demonstrates the possibilities of using high‐quality civil engineering information for scientific purposes.

The question of concord and/or non-concord between such co-referring elements in evaluative right-dislocated constructions is interpreted as an indication of the various differentiations in the speaker’s referential and attitudinal perspective upon already established discourse referents.

description: We show that Ce- and Yb-based Kondo-lattice ferromagnets order mainly along the magnetically hard direction of the ground state Kramers doublet determined by crystalline electric field (CEF). Here we argue that this peculiar phenomenon, that was believed to be rare, is instead the standard case. Moreover, it seems to be independent on the Curie temperature $T_\mathrm{C}$, crystalline structure, size of the ordered moment and type of ground state wave function. On the other hand, all these systems show the Kondo coherence maximum in the temperature dependence of the resistivity just above $T_\mathrm{C}$ which indicates a Kondo temperature of a few Kelvin. An important role of fluctuations is indicated by the non-mean-field like transition in specific heat measurements as well as by the suppression of this effect by a strong Ising-like anisotropy. We discuss possible theoretical scenarios.

description: The aim of the paper is to determine the distinct discourse-building roles of so and it, in their predicate- and proposition-anaphoric guise. Is the choice between them determined by the syntactic or semantic nature of their 'antecedent', or of the context in which the choice between them is to be made? Or do they in fact themselves determine their 'antecedent' (or at least superimpose upon it a characteristically distinctive interpretation)? I shall argue for the latter analysis, indicating a range of factors (of a mainly semantic nature) which co-determine both the choice between these two anaphors, and their full utterance-level interpretation. A wide range of attested and constructed examples will be presented as the basis for the discussion.

The effect of adiabatic losses on spectra of stationary jets and the origin of soft radio spectra of accreting black-hole sources

description: It has been suggested that adiabatic energy losses are not effective in stationary jets, where the jet expansion is not associated with net work. Here, we study jet solutions without them, assuming that adiabatic losses are balanced by electron reacceleration. The absence of effective adiabatic losses makes electron advection along the jet an important process, and we solve the electron kinetic equation including that process. We find analytical solutions for the case of conical jets with advection and synchrotron losses. We show that accounting for adiabatic losses in the case of sources showing soft partially self-absorbed spectra with the spectral index of $α<0$ in the radio-to-IR regime requires deposition of large amounts of energy at large distances in the jet. On the other hand, such spectra can be accounted for by advection of electrons in the jet. We compare our results to the quiescent spectrum of the blazar Mrk 421. We find its soft radio-IR spectrum can be fitted either by a model without adiabatic losses and advection of electrons or by one with adiabatic losses, but the latter requires injection of a very large power at large distances.

At the late stage of the spinodal decomposition process, particles significantly slow down the domain growth, in qualitative agreement with earlier experimental data.

description: No abstracts are to be cited without prior reference to the author.Synthesis of a multi‐decade time‐series of ichthyoplankton and environmental data from the Gulf of Alaska (GOA) reveal synchronies and similarities in abundance trends and links to environmental variables that reflect life‐history and ecological variation among species, particularly during early ontogeny. Similarities in response to environmental forcing are apparent when there are similarities in early life‐history exposure to the environment. A pilot study on selected fish species in the GOA illustrates the utility of incorporating multiple early life‐history characteristics into a comparative analysis of environmental exposure–response coupling among marine fish populations. Ordination by principal component analysis of a matrix of species by reproductive and early life‐history attributes resulted in a wide distribution of species along three primary early life‐history gradients. These gradients are synonymous with the quantity of egg and larval production, the phenology of egg and larval production, and the ubiquity of larvae, the latter representing the temporal and spatial “spread” of larvae. From this analysis, a conceptual model is proposed for GOA fish species early life‐history representing trade‐offs in adaptation to prevailing environmental conditions, and associated risk and resilience factors that set the initial recruitment response to environmental forcing. The working hypothesis for this ongoing research is that we can utilize similarities in reproductive and early life‐history characteristics among species to identify: (i) ecologically determined species groups that are predisposed to respond to environmental forcing during early life in similar ways, and (ii) plausible environmental predictors of recruitment variation.

description: We investigate the process of nuclear excitation via a two-photon electron transition (NETP) for the case of the doubly charged thorium. The theory of the NETP process has been devised originally for heavy helium-like ions. In this work, we study this process in the nuclear clock isotope $^{229}$Th in the $2+$ charge state. For this purpose, we employ a combination of configuration interaction and many-body perturbation theory to calculate the probability of NETP in resonance approximation. The experimental scenario we propose for the excitation of the low lying isomeric state in $^{229}$Th is a circular process starting with a two-step pumping stage followed by NETP. The ideal intermediate steps in this process depend on the supposed energy $\hbarω_N$ of the nuclear isomeric state. For each of these energies, the best initial state for NETP is calculated. Special focus is put on the most recent experimental results for $\hbarω_N$.

description: A new event mixing constraint, namely invariant-mass/energy hierarchy correspondence (IMEHC) cut, is introduced for the low-multiplicity event mixing technique for the purpose of measuring Bose-Einstein correlations (BEC) in exclusive reactions with $ππX$ final state particles.The mixing cut is relevant to the hierarchy of the invariant mass of $πX$ system and two bosons energy hierarchy. Numerical tests are performed to check the validity of the new mixing method. As long as the measurements of BEC parameters $r_0$ and $λ_2$ are considered, this new mixing method is effective to observe BEC effects and the systematic bias of $r_0$ and $λ_2$ are smaller than the previously proposed mixing cut.

Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.Recent work suggests that recruitment of larvae and juveniles is affected by traits of organisms such as body size. We propose an integrative framework to study recruitment that incorporates organism traits. The main argument is that mortality should be affected by the product of population density and body size, which defines the amount of resources consumed by recruits. This amount defines the level of mortality owing to resource limitation. We apply this model to the recruitment of the barnacle Semibalanus balanoides from two different shores. In both shores postsettlement survival is better explained by models based on density and operculum area as a trait than by models based on density alone. Operculum area, a trait that does not respond plastically to changes in barnacle density, is a better predictor than basal area that responds to density. Survival follows a sigmoid function with a threshold at 30–40% of percentage cover. In future these models may incorporate physiological processes and evaluate the role of metabolism on recruitment patterns, facilitating the study of recruitment from the perspective of oceanographic‐ and climaterelated processes, such as match–mismatch and temperature increase. More generally, we emphasize the need to develop a theory of recruitment integrating individual variability to processes operating at the population level.

description: The vortex configurations in the Bose-Einstein condensate of the mixture of two different spin states |F=1,m_f=-1> and |2,1> of ^{87}Rb atoms corresponding to the recent experiments by Matthews et. al. (Phys. Rev. Lett. 83, 2498 (1999)) are considered in the framework of the Thomas-Fermi approximation as functions of N_2/N_1, where N_1 is the number of atoms in the state |1,-1> and N_2 - in the state |2,1>. It is shown that for nonrotating condensates the configuration with the |1,-1> fluid forming the shell about the |2,1> fluid (configuration "a") has lower energy than the opposite configuration (configuration "b") for all values of N_2/N_1. When the |1,-1> fluid has net angular momentum and forms an equatorial ring around the resting central condensate |2,1>, the total energy of the system is higher than the ground energy, but the configuration "a" has lower energy than the configuration "b" for all N_2/N_1. On the other hand, when the |2> fluid has the net angular momentum, for the lowest value of the angular momentum \hbar l (l=1) there is the range of the ratio N_2/N_1 where the configuration "b" has lower energy than the configuration "a". For higher values of the angular momentum the configuration "b" is stable for all values of N_2/N_1.

description: No abstracts are to be cited without prior reference to the author.Northeast Arctic haddock is characterized by wide-range fluctuations in the year-class strength. The effect of spawning stock size on the year-class strength for the entire period did not exceed 4.6%. Mortality-survival ratio during early life of this population proved to be much more dependent on the ambient conditions than on the parental stock abundance. To describe the quality of environment during early ontogeny of the population the year-class survival index was established as the ratio of abundance of 3-year olds to the spawning stock biomass in the year of the generation birth. The analysis of multi-year variability in survival factors allowed for establishing three recurrent types of conditions, namely, favorable, moderate and unfavorable. The influence of the spawning stock size within each type of conditions constituted 83.4, 53.8, and 28.9%, respectively, and it was described by the regression equations with the correspondent determination coefficients of 0.73, 0.63, and 0.41. The survival of NEA haddock depends to a great extent on water temperature conditions, which, in turn, are determined by the large-scale atmospheric patterns over the North Atlantic. There is a strong positive relationship of survival indices of haddock with duration of warm season and dates of its beginning and end in the year of spawning. This allows forecasting the three year olds abundance at the known SSB three years in advance.

description: In this paper, we study fixed points of N-point gravitational lenses. We use complex form of lens mapping to study fixed points. Complex form has an advantage over coordinate one because we can describe N-point gravitational lens by system of two equation in coordinate form and we can describe it by one equation in complex form. We can easily transform the equation, which describe N-point gravitational lens, into polynomial equation that is convenient to use for our research. In our work, we present lens mapping as a linear combination of two mapping: complex analytical and identity mapping. Analytical mapping is specified by analytical function (deflection function). We studied necessary and sufficient conditions for the existence of deflection function and proved some theorems. Deflection function is analytical, rational, its zeroes are fixed points of lens mapping and their number is from 1 to N-1, poles of deflection function are coordinates of point masses, all poles are simple, the residues at the poles are equal to the value of point masses.\\ We used Gauss-Lucas theorem and proved that all fixed points of lens mapping are in the convex polygon. Vertices of the polygon consist of point masses. We proved theorem that can be used to find all fixed point of lens mapping. On the basis of the above, we conclude that one-point gravitational lens has no fixed points, 2-point lens has only 1 fixed point, 3-point lens has 1 or 2 fixed points. Also we present expressions to calculate fixed points in 2-point and 3-point gravitational lenses. We present some examples of parametrization of point masses and distribution of fixed points for this parametrization.

description: Membrane technology is playing an important role in the separation of magnesium and lithium from brines, and high Li/Mg selectivity in membrane separation is constantly pursued. However, it has been found that there is always a selectivity variation when using individual salts to replace the salt mixture as the feed, implying that the interference mechanism of mixed cations remains unclear. Herein, by using covalent organic frameworks as an example, we investigate the ion transport behaviours through nanopores with the mixed and individual feeding of LiCl and MgCl2 via molecular dynamics simulations. There is an evident reduced Li/Mg selectivity while the mixed-salt feed is applied. It is revealed that Li+ interacts strongly with pore-wall atoms while Mg2+ with water molecules. Consequently, Mg2+ tends to flow with water molecules while Li+ is prone to adsorb to the pore wall. The presence of Mg2+ inside nanopores will bring down water flux and seriously reduce the transport of Li+ inside nanopores. The advantage of pre-adsorbing for Li+, which promotes the Li/Mg selectivity, is completely balanced out, thus reducing selectivity. Our results also suggest that impeding the entrance of Mg2+ into membranes will avoid the selectivity drop not only because of the sieving effecting.

description: The interlayer magnetoresistance of layered metals in a tilted magnetic field is calculated for two distinct models for the interlayer transport. The first model involves coherent interlayer transport and makes use of results of semi-classical or Bloch-Boltzmann transport theory. The second model involves weakly incoherent interlayer transport where the electron is scattered many times within a layer before tunneling into the next layer. The results are relevant to the interpretation of experiments on angular-dependent magnetoresistance oscillations (AMRO) in quasi-one- and quasi-two-dimensional metals. We find that the dependence of the magnetoresistance on the direction of the magnetic field is identical for both models except when the field is almost parallel to the layers. An important implication of this result is that a three-dimensional Fermi surface is not necessary for the observation of the Yamaji and Danner oscillations seen in quasi-two- and quasi-one-dimensional metals, respectively. A universal expression is given for the dependence of the resistance at AMRO maxima and minima on the magnetic field and scattering time (and thus the temperature). We point out three distinctive features of coherent interlayer transport: (i) a beat frequency in the magnetic oscillations of quasi-two-dimensional systems, (ii) a peak in the angular-dependent magnetoresistance when the field is sufficiently large and parallel to the layers, and (iii) a crossover from a linear to a quadratic field dependence for the magnetoresistance when the field is parallel to the layers. Properties (i) and (ii) are compared with published experimental data for a range of quasi-two-dimensional organic metals and for Sr2RuO4.

description: We study polaron excitations induced by an impurity interacting with a two-dimensional $p+ip$ Fermi superfluid. As the Fermi-Fermi pairing interaction is tuned, the background Fermi superfluid undergoes a topological phase transition. We show that such a transition is accompanied by a discontinuity in the second derivative of the polaron energy, regardless of the impurity-fermion interaction. We also identify a polaron to trimer crossover when the Fermi superfluid is in the strongly interacting, thus topologically trivial, regime. However, the trimer state is metastable against the molecular state where the impurity binds a Bogoliubov quasiparticle from the Fermi superfluid. By comparing the polaron to molecule transition in our system with that of an impurity in a noninteracting Fermi sea, we find that pairing interactions in the background Fermi superfluid effectively facilitate the impurity-fermion binding. Our results suggest the possibility of using the impurity as a probe for detecting topological phase transitions in the background; they also reveal interesting competitions between various many-body states in the system.

On Because Causality in Scientific Discourse
Creators: name: Sidiropoulou, Maria
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1991

description: Because is used for intentional transmission of causal information in discourse. In scientific writing, it is widely used connecting propositions which exhibit relations of ‘logical inference’ between them. Its use can, thus, be described in terms of underlying semantic / pragmatic structures rather than syntactic ones. In this paper, semantic and pragmatic considerations concerning because connections are discussed and the use of the connective in scientific discourse is commented upon.

description: No abstracts are to be cited without prior reference to the author.Dispersal of fish larvae into unfavourable areas may be devastating for early life stage survival and recruitment. In highly dynamic upwelling environments, such as the northwest African region, it is critical to understand the magnitude of offshore larval transport. This upwelling system remains still largely unstudied in terms of early life‐history stages of fish, even for the most commercial species (European sardine and anchovy). In this work, we describe for the first time the entire larval fish community present in the area in spring, identifying a coastal and an oceanic larval assemblage. Our spring sampling identified two filament–eddy complexes between Cape Juby and Cape Bojador. The interaction of these mesoscale structures not only influenced the distribution of neritic species, but also oceanic species. Neritic larvae (sardine, anchovy, mackerel) were retained by the upwelling front, located some 100 km offshore. The interaction between the anticyclonic and the cyclonic eddy may then work as a mechanism to return the larvae to the African coast. On the other hand, oceanic species were present at nearly all sampling stations, although there were accumulations observed in a northern area near the shelf break (enhanced by the cyclonic eddy) and southern area owing to the interaction of the southern filament–anticyclonic eddy complex. Consequences of larval dispersal for survival and recruitment for the relevant species are discussed in the light of the results.

Supplementary material from Anisotropic residual stresses in arteries

description: The paper provides a deepened insight into the role of anisotropy in the analysis of residual stresses in arteries. Residual deformations are modelled following Holzapfel and Ogden (Holzapfel and Ogden 2010, J. R. Soc. Interface 7, 787–799. (doi:10.1098/rsif.2009.0357)), which is based on extensive experimental data on human abdominal aortas (Holzapfel et al. 2007, Ann. Biomed. Eng. 35, 530–545. (doi:10.1007/s10439-006-9252-z)) and accounts for both circumferential and axial residual deformations of the individual layers of arteries—intima, media and adventitia. Each layer exhibits distinctive nonlinear and anisotropic mechanical behaviour originating from its unique microstructure; therefore, we use the most general form of strain-energy function (Holzapfel et al. 2015, J. R. Soc. Interface 12, 20150188. (doi:10.1098/rsif.2015.0188)) to derive residual stresses for each layer individually. Finally, the systematic experimental data (Niestrawska et al. 2016, J. R. Soc. Interface 13, 20160620. (doi:10.1098/rsif.2016.0620)) on both mechanical and structural properties of the different layers of the human abdominal aorta facilitate our discussion on (i) the importance of anisotropy in modelling residual stresses; (ii) the variability of residual stresses within the same class of tissue, the abdominal aorta; (iii) the limitations of conventional opening angle method to account for complex residual deformations; and (iv) the effect of residual stresses on the loaded configuration of the aorta mimicking in vivo conditions.

description: We report resonant x-ray scattering studies of charge and orbital order in Pr_{1-x}Ca_{x}MnO_3 with x=0.4 and 0.5. Below the ordering temperature, T_O=245 K, the charge and orbital order intensities follow the same temperature dependence, including an increase at the antiferromagnetic ordering temperature, T_N. High resolution measurements reveal, however, that long range orbital order is never achieved. Rather, an orbital domain state is formed. Above T_O, the charge order fluctuations are more highly correlated than the orbital fluctuations. Similar phenomenology is observed in a magnetic field. We conclude that the charge order drives the orbital order at the transition.

description: Nanoparticles with their specific properties newly have drawn a great deal of attention of researchers [1-3]Yttrium iron Garnet magnetic nanoparticles (YIG-NPs) are promising materials with novel applications in microwave, spintronics, magnonics, and magneto-optical devices. However, achieving stable and remarkable magnetic YIG-NPs has been remaining as a great challenge. In this paper, synthesized YIG-NPs by modifying co-precipitation (MCP) method is reported. Structural and magnetic properties of final products are compared to those of the materials prepared by citrate-nitrate (CN) method. Smaller crystals and particle size have been found by MCP method comparing to that of synthesized by CN method. Using a relatively low annealing temperatures for both sets of samples (~700 °C), the final YIG samples prepared by MCP method show more structural purity than those made by CN method. Higher saturation magnetization (Ms) and lower coercivity (Hc) are observed in MCP YIG sample (23.23 emu/g 36 and 30.1 Oe) than the CN prepared YIG sample (16.43 emu/g and 44.95 Oe). The Curie temperature is measured to be 569 °C for the MCP YIG sample determined from set of Ms measurement at different temperatures ranging from 80-600 K. These findings lead to significant improvement in quality of synthesized (synthetic methods) of YIG-NPs.

description: We analyze the possibility of black holes pair creation induced by three dimensional wormholes. Although this spacetime configuration is nowadays hard to suppose, it can be very important in the early universe, when the wormhole spacetime foam representation can be meaningful. We compare our approach with the no-boundary prescription of Hartle-Hawking.
