description: We present 1998 HST observations of M87 which yield the first single-epoch optical and radio-optical spectral index images of the jet at $0.15''$ resolution. We find $ \approx 0.67$, comparable to previous measurements, and $ \approx 0.9$ ($F_ν\propto ν^{-α}$), slightly flatter than previous workers. Reasons for this discrepancy are discussed. These observations reveal a large variety of spectral slopes. Bright knots exhibit flatter spectra than interknot regions. The flattest spectra ($α_o \sim 0.5-0.6$; comparable to or flatter than $α_{ro}$) are found in two inner jet knots (D-East and HST-1) which contain the fastest superluminal components. In knots A, B and C, $α_o$ and $α_{ro}$ are essentially anti-correlated. Near the flux maxima of knots HST-1 and F, changes in $α_{ro}$ lag changes in $α_o$, but in knots D and E, the opposite relationship is observed. This is further evidence that radio and optical emissions in the M87 jet come from substantially different physical regions. The delays observed in the inner jet are consistent with localized particle acceleration, with $t_{acc} << t_{cool}$ for optically emitting electrons in knots HST-1 and F, and $t_{acc} \sim t_{cool}$ for optically emitting electrons in knots D and E. Synchrotron models yield $ν_B \gsim 10^{16}$ Hz for knots D, A and B, and somewhat lower values, $ν_B \sim 10^{15}- 10^{16}$ Hz, in other regions. If X-ray emissions from knots A, B and D are co-spatial with optical and radio emission, we can strongly rule out the ``continuous injection'' model. Because of the short lifetimes of X-ray synchrotron emitting particles, the X-ray emission likely fills volumes much smaller than the optical emission regions.

description: Nonreciprocal circuit elements form an integral part of modern measurement and communication systems. Mathematically they require breaking of time-reversal symmetry, typically achieved using magnetic materials and more recently using the quantum Hall effect, parametric permittivity modulation or Josephson nonlinearities. Here, we demonstrate an on-chip magnetic-free circulator based on reservoir engineered optomechanical interactions. Directional circulation is achieved with controlled phase-sensitive interference of six distinct electro-mechanical signal conversion paths. The presented circulator is compact, its silicon-on-insulator platform is compatible with both superconducting qubits and silicon photonics, and its noise performance is close to the quantum limit. With a high dynamic range, a tunable bandwidth of up to 30 MHz and an in-situ reconfigurability as beam splitter or wavelength converter, it could pave the way for superconducting qubit processors with integrated and multiplexed on-chip signal processing and readout.

description: No abstracts are to be cited without prior reference to the author.International coordinated trawl surveys have been carried out in the Baltic Sea in quarter 1 and 4 since 2001 which use standardized gear types (small and larger version) and allocation of hauls based on agreed procedures. These surveys replaced the former national surveys where national gears were used and which were concentrated in quarter 1 and not internationally coordinated. The total number of hauls increased to about 190 in mean in quarter 4 and to about 300 fishing stations in quarter 1 in mean between 2002 and 2007. The new method of allocating the hauls guaranteed a good coverage of the total distribution area independent of the total number of planned stations. The catch per hour in units of the large standard gear by length intervals and age groups were used to study the distribution patterns of cod and flounder and to analyze the used stratification of the Baltic Sea during the Baltic International Trawl Surveys. Stratification of the Baltic Sea, which is optimal for all length groups of cod and flounder, does not exist because the highest densities of small and large cod and flounder were located in areas, which only partly overlapped. The correlation coefficients between the CPUE values of different length groups were low due to the patchy distribution of the different length groups of cod and flounder. Significant changes of the horizontal distributions are possible from survey to survey. The studies suggest that the depth stratification, which is a compromise to estimate stock indices based on BITS, can be used for the surveys in quarter 1 and 4. Nevertheless, the quality of the stock indices can probably be improved by the extension or intensification of the surveys into waters shallower than 20 m and by the use of larger strata, which enclose the areas with similar distribution patterns of CPUE values

description: Large scale real number computation is an essential ingredient in several modern mathematical proofs. Because such lengthy computations cannot be verified by hand, some mathematicians want to use software proof assistants to verify the correctness of these proofs. This paper develops a new implementation of the constructive real numbers and elementary functions for such proofs by using the monad properties of the completion operation on metric spaces. Bishop and Bridges's notion of regular sequences is generalized to, what I call, regular functions which form the completion of any metric space. Using the monad operations, continuous functions on length spaces (a common subclass of metric spaces) are created by lifting continuous functions on the original space. A prototype Haskell implementation has been created. I believe that this approach yields a real number library that is reasonably efficient for computation, and still simple enough to easily verify its correctness.

description: Existing block-diagonal representation researches mainly focuses on casting block-diagonal regularization on training data, while only little attention is dedicated to concurrently learning both block-diagonal representations of training and test data. In this paper, we propose a discriminative block-diagonal low-rank representation (BDLRR) method for recognition. In particular, the elaborate BDLRR is formulated as a joint optimization problem of shrinking the unfavorable representation from off-block-diagonal elements and strengthening the compact block-diagonal representation under the semi-supervised framework of low-rank representation. To this end, we first impose penalty constraints on the negative representation to eliminate the correlation between different classes such that the incoherence criterion of the extra-class representation is boosted. Moreover, a constructed subspace model is developed to enhance the self-expressive power of training samples and further build the representation bridge between the training and test samples, such that the coherence of the learned intra-class representation is consistently heightened. Finally, the resulting optimization problem is solved elegantly by employing an alternative optimization strategy, and a simple recognition algorithm on the learned representation is utilized for final prediction. Extensive experimental results demonstrate that the proposed method achieves superb recognition results on four face image datasets, three character datasets, and the fifteen scene multi-categories dataset. It not only shows superior potential on image recognition but also outperforms state-of-the-art methods.

description: We elucidate the interplay between gauge and supersymmetry anomalies in six-dimensional $N=1$ supergravity with generalized couplings between tensor and vector multiplets. We derive the structure of the five-dimensional supergravity resulting from the $S_1$ reduction of these models and give the constraints on Chern-Simons couplings that follow from duality to $M$ theory compactified on a Calabi-Yau threefold. The duality is supported only on a restricted class of Calabi-Yau threefolds and requires a special type of intersection form. We derive five-dimensional central-charge formulas and discuss briefly the associated phase transitions. Finally, we exhibit connections with $F$-theory compactifications on Calabi-Yau manifolds that admit elliptic fibrations. This analysis suggests that $F$ theory unifies Type-$IIb$ three-branes and $M$-theory five-branes.

description: To understand the conditions that produce white-light (WL) enhancements in solar flares, a statistical analysis of visible continuum data as observed by Hinode/Solar Optical Telescope (SOT) was performed. In this study, approximately 100 flare events from M- and X-class flares were selected. The time period during which the data were recorded spans from January 2011 to February 2016. Of these events, approximately half are classified as white-light flares (WLFs), whereas the remaining events do not show any enhancements of the visible continuum (non-WLF; NWL). In order to determine the existence of WL emission, running difference images of not only the Hinode/SOT WL (G-band, blue, green, and red filter) data but also the Solar Dynamics Observatory/Helioseismic and Magnetic Imager continuum data are used. A comparison between these two groups of WL data in terms of duration, temperature, emission measure of GOES soft X-rays, distance between EUV flare ribbons, strength of hard X-rays, and photospheric magnetic field strength was undertaken. In this statistical study, WLF events are characterized by a shorter time-scale and shorter ribbon distance compared with NWL events. From the scatter plots of the duration of soft X-rays and the energy of non-thermal electrons, a clear distinction between WLF and NWL events can be made. It is found that the precipitation of large amounts of accelerated electrons within a short time period plays a key role in generating WL enhancements. Finally, it was demonstrated that the coronal magnetic field strength in the flare region is one of the most important factors that allow the individual identification of WLF events from NWL events.

description: Liquid state nuclear magnetic resonance (NMR) techniques have produced some spectacular successes in the construction of small quantum computers, and NMR is currently by far the leading technology for quantum computation. There are, however, a number of significant problems with any attempt to scale up the technology to produce computers of any useful size. While it is probable that some of these will be successfully sidestepped during the next few years, it is unlikely that they will all be solved; thus current liquid state NMR techniques are unlikely to provide a viable technology for practical quantum computation.

description: We analyze and compare the angular deviations for an optical beam reflected by and transmitted through a dielectric triangular prism. The analytic expressions derived for the angular deviations hold for arbitrary incidence angles. For incidence approaching the internal and external Brewster angles, the angular deviations transverse magnetic waves present the same behavior leading to the well-known giant Goos-Haenchen angular shift. For incidence near the critical angle a new region of large shift is seen both for transverse magnetic and transverse electric waves. While a direct measuring procedure is better in the vicinity of the Brewster region, a weak measurement breaks off the giant Goos-Haenchen effect, preserving the amplification in the critical region. We discuss under which conditions it is possible to optimize the amplification and we also determine when a weak measurement is preferred to a direct measuring procedure.

description: No abstracts are to be cited without prior reference to the author.Cod and sprat constitute much of the fish biomass in and catches from the Baltic Sea. Both species reproduce in pelagic offshore areas, and, therefore, are subjected to similar environmental conditions at least to a certain extent. The eastern Baltic cod stock is biologically distinct from the western Baltic one, and it is managed as a separate unit. Sprat is regarded as a single stock, and it is assessed and managed accordingly. In the Baltic proper, a number of local herring stocks can be distinguished based on spawning areas, otolith shape, and maturation or growth rates. However, these populations have been merged into one Central Baltic Stock (CBH, SD 25-29+32) for assessment and management purposes. The only exception to this is the Gulf of Riga herring (GoRH), which is assessed and managed separately.

description: The entropic moments of the probability density of a quantum system in position and momentum spaces describe not only some fundamental and/or experimentally accessible quantities of the system, but also the entropic uncertainty measures of Rényi type which allow one to find the most relevant mathematical formalizations of the position-momentum Heisenberg's uncertainty principle, the entropic uncertainty relations. It is known that the solution of difficult three-dimensional problems can be very well approximated by a series development in $1/D$ in similar systems with a non-standard dimensionality $D$; moreover, several physical quantities of numerous atomic and molecular systems have been numerically shown to have values in the large-$D$ limit comparable to the corresponding ones provided by the three-dimensional numerical self-consistent field methods. The $D$-dimensional hydrogenic atom is the main prototype of the physics of multidimensional many-electron systems. In this work we rigorously determine the leading term of the Rényi entropies of the $D$-dimensional hydrogenic atom at the limit of large $D$. As a byproduct, we show that our results saturate the known position-momentum Rényi-entropy-based uncertainty relations.

description: No abstracts are to be cited without prior reference to the author.Abstract - Eutrophication is the most serious challenge for the Baltic Sea environmental policy. However, the impacts of eutrophication on the Baltic food web are currently not fully understood. Here, we studied the ecosystem effects of changing nutrient (N and P) conditions with the Ecopath with Ecosim -software (EwE). Unlike previous studies, the entire Baltic Sea is now covered with spatial resolution (2D) and the impact of currents, salinity, bottom hypoxia and differential fish nursery sites are specified. The food web model is based on Baltic Sea data from year 1996 and contains over 30 functional groups including the most important commercial fish species, cod (Gadus morhua), herring (Clupea harengus membras) and sprat (Sprattus sprattus). Already 5 and 10 percent modelled reductions in nutrient inputs were found to impact the entire food web and this impact increased almost linearly with increased reductions. In general, a 10 percent decrease in N reduced biomasses more than a simultaneous 5 percent reduction in the input of both nutrients. The groups most influenced were spring and summer phytoplankton with maximum mean biomass decreases of 9 and 4 percent, respectively, with a 10 percent reduction in both N and P. Cyanobacteria biomasses decreased only with reductions in P. Reductions in fish biomasses were smaller than the ones in primary production. However, a clear response to food availability was detected. The impact of nutrient reductions was spatially variable.

description: The Alpine Fault, located in the South Island, New Zealand, is a subject of intense geological study due to its potential to trigger large earthquakes. It encompasses a complex system with the interplay of mechanics, thermodynamics, and ﬂuid. Gaining insights into these systems not only enhances our understanding of the fault but also holds the potential to guide risk mitigation eﬀorts.The damage extent and fracture networks within the metamorphic rock mass adjacent to the fault can be eﬀectively characterized by seismic anisotropy, an elastic property of rock, where seismic waves travel at diﬀerent speeds with variation directions. This thesis presents a comprehensive exploration of seismic anisotropy in the hanging wall immediately adjacent to the principal slip zone of the Alpine Fault in New Zealand. Leveraging the borehole seismic data from a unique scientiﬁc drilling project and advanced numerical modeling techniques, the ultimate goal is to invert and parameterize the bulk seismic anisotropy.Motivated by these challenges, the thesis undertakes several key initiatives: The ﬁrst eﬀort focuses on gaining a comprehensive understanding of an innovative method for seismic measurement: Distributed Acoustic Sensing (DAS) – examining its operational principles, factors inﬂuencing observed wavelets, and how it contrasts with traditional point sensors for accurate interpretation. Subsequently, the research introduces the implementation of an open-source seismic wave solver designed for modeling elastic wave propagation in complicated anisotropic media. This solver is further optimized for computational eﬃciency with its performance rigorously benchmarked.With this preparedness, the inversion is further facilitated by high-performance computing (HPC) and a deep-learning algorithm speciﬁcally designed for automatically picking transit times. The inverted bulk elastic constants, compared to the intact rock, reveal 28% to 35% reductions in qP-wave velocity, characterizing the damage due to mesoscale fracture. Further analysis sheds light on the existence of orthogonal fracture sets and an intricate geometrical arrangement that agree with the previous borehole image log. This represents an advancement in our ability to characterize and understand the geologic processes with seismic anisotropy.

description: In nuclei with valence nucleons are say identical nucleons and say these nucleons occupy several-$j$ orbits, then it is possible to consider pair creation operator $S_+$ to be a sum of the single-$j$ shell pair creation operators $S_+(j)$ with arbitrary phases, $S_+=\sum_j α_j S_+(j); α_j=\pm 1$. In this situation, it is possible to define multi-orbit or generalized seniority that corresponds to the quasi-spin $SU(2)$ algebra generated by $S_+$, $S_-=(S_+)^\dagger$ and $S_0=(\hat{n} -Ω)/2$ operators; $\hat{n}$ is number operator and $Ω=[\sum_j (2j+1)]/2$. There are now multiple pairing quasi-spin $SU(2)$ algebras. Also, the $α_j$'s and the generators of the corresponding generalized seniority generating sympletic algebras $Sp(2Ω)$ in $U(2Ω) \supset Sp(2Ω)$ have one-to-one correspondence. Using these, derived are the special seniority selection rules for electromagnetic transitions. A particular choice for $α_j$'s as advocated by Arvieu and Moszkowski (AM) in the past gives pairing Hamiltonians having maximum correlation with well known effective interactions. The various results derived for identical fermion systems are shown to extend to identical boson systems with the bosons occupying several-$\ell$ orbits as for example in $sd$, $sp$, $sdg$ and $sdpf$ IBM's. The quasi-spin algebra here is $SU(1,1)$ and the generalized seniority quantum number is generated by $SO(2Ω)$ in $U(2Ω) \supset SO(2Ω)$. The different $SO(2Ω)$ algebras here will be important in the study of quantum phase transitions and order-chaos transitions in nuclei.

description: While the role of the free energy barrier during nucleation is a text-book subject the importance of the kinetic factor is frequently underestimated. We obtained both quantities from molecular dynamics (MD) simulations for the pure Ni and B2 phases in the Ni50Al50 and Cu50Zr50 alloys. The free-energy barrier was found to be higher in Ni but the nucleation rate is much lower in the Ni50Al50 alloy which was attributed to the ordered nature of the B2 phase. Since the Cu50Zr50 B2 phase can has even smaller fraction of the anti-site defects its nucleation is never observed in the MD simulation.

To derive the mass fraction, we relate FGS 3 fringe scanning observations of the science target to a reference frame provided by fringe tracking observations of a surrounding star field. We obtain an absolute parallax $π_{abs} = 98.0 \pm 0.4$ milliseconds of arc, yielding ${\cal M}_A = 0.379 \pm 0.005{\cal M}_{\sun}$ and ${\cal M}_B= 0.192 \pm 0.003 {\cal M}_{\sun}$, high quality component masses with errors of only 1.5%.

description: This paper is based on and advocates the trend in software engineering of extending the use of software patterns as means of structuring solutions to software development problems (be they motivated by best practice or by company interests and policies). The paper argues that, on the one hand, this development requires tools for automatic organisation, retrieval and explanation of software patterns. On the other hand, that the existence of such tools itself will facilitate the further development and employment of patterns in the software development process. The paper analyses existing pattern representations and concludes that they are inadequate for the kind of automation intended here. Adopting a standpoint similar to that taken in the semantic web, the paper proposes that feasible solutions can be built on the basis of ontological representations.

A New RSOS Restriction of the Zhiber-Mikhailov-Shabat Model and $Φ_{(1,5)}$ Perturbations of Nonunitary Minimal Models

description: The RSOS restriction of the Zhiber-Mikhailov-Shabat (ZMS) model is investigated. It is shown that in addition to the usual RSOS restriction, corresponding to $Φ_{(1,2)}$ and $Φ_{(2,1)}$ perturbations of minimal CFT, there is another one which yields $Φ_{(1,5)}$ perturbations of non-unitary minimal models. The new RSOS restriction is carried out and the particular case of the minimal models ${\cal M}_{(3,10)}$, ${\cal M}_{(3,14)}$ and ${\cal M}_{(3,16)}$ is discussed in detail. In the first two cases, while the mass spectra of the two RSOS restrictions are the same, the bootstrap systems and the detailed amplitudes are different. In the third case, even the spectra of the two RSOS restrictions are different. In addition, for ${\cal M}_{(3,10)}$ an interpretation in terms of the tensor product of two copies of ${\cal M}_{(2,5)}$ is given.
description: several typos corrected; error in (3,14) S-matrix found and corrected; the introductory section on RSOS restriction is rewritten. The exposition is changed at some points to improve clarity and reference to 'duality' is avoided

description: No abstracts are to be cited without prior reference to the author.The Estuary and Gulf of St. Lawrence (EGSL) represents one of the largest and most productive estuarine/marine ecosystems in Canada and in the world. However, the EGSL ecosystem is affected by a wide variety of human activities that pose significant threats to its integrity and the sustainable use of its resources. These include fisheries, navigation, mariculture activities, coastal development, recreational use (including marine mammal observation), climate change, and several land–based activities that occur along the EGSL shores and in coastal and upstream rivers and tributaries, including industrial and municipal activities, agriculture, and river damming (for water level control and hydropower). In 2005, the Government of Canada initiated the Oceans Action Plan (OAP) in order to implement an ecosystem-based management approach for five Large Ocean Management Areas (LOMAs), including the Estuary and Gulf of St. Lawrence. This presentation provides an overview of the EGSL ecosystem structure and functioning, as well as its human pressures, through a summary of the scientific tools that were developed within this initiative. As well, a brief description of governance approaches currently being developed in the area to implement these tools is also provided.

description: Designing and developing a millimetre-wave(mmWave) based mobile Radio Access Technology (RAT) in the 6-100 GHz frequency range is a fundamental component in the standardization of the new 5G radio interface, recently kicked off by 3GPP. Such component, herein called the new mmWave RAT, will not only enable extreme mobile broadband (eMBB) services,but also support UHD/3D streaming, offer immersive applications and ultra-responsive cloud services to provide an outstanding Quality of Experience (QoE) to the mobile users. The main objective of this paper is to develop the network architectural elements and functions that will enable tight integration of mmWave technology into the overall 5G radio access network (RAN). A broad range of topics addressing mobile architecture and network functionalities will be covered-starting with the architectural facets of network slicing, multiconnectivity and cells clustering, to more functional elements of initial access, mobility, radio resource management (RRM) and self-backhauling. The intention of the concepts presented here is to lay foundation for future studies towards the first commercial implementation of the mmWave RAT above 6 GHz.

Uncertainty quantification for complex systems with very high dimensional response using Grassmann manifold variations

description: This paper addresses uncertainty quantification (UQ) for problems where scalar (or low-dimensional vector) response quantities are insufficient and, instead, full-field (very high-dimensional) responses are of interest. To do so, an adaptive stochastic simulation-based methodology is introduced that refines the probability space based on Grassmann manifold variations. The proposed method has a multi-element character discretizing the probability space into simplex elements using a Delaunay triangulation. For every simplex, the high-dimensional solutions corresponding to its vertices (sample points) are projected onto the Grassmann manifold. The pairwise distances between these points are calculated using appropriately defined metrics and the elements with large total distance are sub-sampled and refined. As a result, regions of the probability space that produce significant changes in the full-field solution are accurately resolved. An added benefit is that an approximation of the solution within each element can be obtained by interpolation on the Grassmann manifold without the need to develop a mathematical surrogate model. The method is applied to study the probability of shear band formation in a bulk metallic glass using the shear transformation zone theory.

description: The pressure shifts of the $3s4s^3S_1 \to 3s3p^3P_{0,1,2}$ transition of magnesium atoms immersed in superfluid helium have been measured at $(1.3\pm0.1 )$K between saturated vapour pressure and $24 $bar. The wavelength is blue shifted linearly by $(0.07\pm0.01) \frac{nm}{bar}$. This value can be satisfactorily described in the framework of the standard bubble model.

Hydrogen loss and its improved retention in hydrogen plasma treated a-SiNx:H films: ERDA study with 100 MeV Ag7+ ions

description: Hydrogen loss from a-SiNx:H films under irradiation with 100 MeV Ag7+ ions using elastic recoil detection analysis (ERDA) experiments is reported. The results are explained under the basic assumptions of the molecular recombination model. The ERDA hydrogen counts are composed of two distinct hydrogen desorption processes, limited by rapid molecular diffusion in the initial stages of irradiation, and as the fluence progresses a slow process limited by diffusion of atomic hydrogen takes over. Which of the aforesaid processes dominates, is determined by the continuously evolving Hydrogen concentration within the films. The ERDA measurements were also carried out for films treated with low temperature (300 degrees centigrade) hydrogen plasma annealing (HPA). The HPA treated films show an improved diffusion of atomic hydrogen, resulting from healing of weak bonds and passivation of dangling bonds. Further, upon HPA, films also show evolution of hydrogen with significantly higher counts, at advanced fluences, relative to the as-deposited films. These results indicate the potential of HPA towards improved H retention in a-SiNx:H films. The study distinguishes clearly the presence of two diffusion processes in a-SiNx:H whose diffusion rates differ by an order of magnitude, with hydrogen radicals not being able to diffuse beyond ~1 nm from the point of their creation. The results are very relevant for the passivation applications of a-SiNx:H

description: No abstracts are to be cited without prior reference to the author.The coastal resources are exploited by the small scale fisheries, by definition a low investment fishery, characterized by a large number of small boats that use diverse fishing gears and disembarking ports. This fleet seeks to capture fresh product of high commercial value. On the other hand, marine recreational fishing is also a cause of exploitation of the coastal zone, since angling is a popular activity. Recreational fishing is basically an open access activity, considered different from professional/commercial fisheries because they are not subject to the market economic forces.

description: We simulate the stresses induced by temperature changes in a putative hard layer near the surface of comet 67P/Churyumov--Gerasimenko with a thermo-viscoelastic model. Such a layer could be formed by the recondensation or sintering of water ice (and dust grains), as suggested by laboratory experiments and computer simulations, and would explain the high compressive strength encountered by experiments on board the Philae lander. Changes in temperature from seasonal insolation variation penetrate into the comet's surface to depths controlled by the thermal inertia, causing the material to expand and contract. Modelling this with a Maxwellian viscoelastic response on a spherical nucleus, we show that a hard, icy layer with similar properties to Martian permafrost will experience high stresses: up to tens of MPa, which exceed its material strength (a few MPa), down to depths of centimetres to a metre. The stress distribution with latitude is confirmed qualitatively when taking into account the comet's complex shape but neglecting thermal inertia. Stress is found to be comparable to the material strength everywhere for sufficient thermal inertia ($\gtrsim50$ J m$^{-2}$ K$^{-1}$ s$^{-1/2}$) and ice content ($\gtrsim 45\%$ at the equator). In this case, stresses penetrate to a typical depth of $\sim0.25$ m, consistent with the detection of metre-scale thermal contraction crack polygons all over the comet. Thermal fracturing may be an important erosion process on cometary surfaces which breaks down material and weakens cliffs.

description: No abstracts are to be cited without prior reference to the author.The study of the biomass size distribution has become an important tool for confronting aquatic ecosystem complexity. However, it is necessary to analyze the relationship between the parameters/variables that reflect the structure and function of taxonomically described communities with the parameters of normalized biomass size spectra (NBSS). Here, based on the generation of virtual communities and a dynamic predator-prey model, we simulated biomass trajectories over time in size-dependent communities with different network topologies. The analysis is focused on the relationship between the NBSS parameters and the following topological variables of virtual ecological networks: connectance, functional response, predator interference, metabolic types (invertebrates, ectothermic vertebrates), carrying capacity, initial species richness, number of basal species, and the slope of the relationship between trophic level and body size (slopeTL-BS). The simulations show that the NBSS slopes fit with the theoretical expected values for steady-state systems and with empirical NBSS reported for several aquatic ecosystems. The slope of the NBSS is related to the number of size classes and to the slopeTLBS. The simulations also show that a low number of size-classes or a slopeTL-BS closer to zero generates an increment in the range of possible values for the NBSS slope. The predator/prey ratio plays a critical role in the linear patterns observed in the NBSS. The presence of a Type II functional response generates instability, with non chaotic limited cycles, in the species abundance of the virtual community. The simulation of topological changes in virtual ecological networks shows a clear conservative trend in the NBSS.

description: Воспроизводится аргументация, согласно которой такие понятия классической теории истории, как «исторический процесс» и «логика исторического процесса», сегодня требуют если не полного отбрасывания, то радикальной ревизии и переосмысления. С опорой на концепции П. Вена кратко намечены принципы альтернативного исторического дискурса, в котором указанные понятия сохраняются лишь локально, но не глобально, и приведены их конкретные примеры.
