description: Here we describe 41 brachiopod species belonging to the orders Productida, Orthotetida, Orthida, Rhynchonellida, Athyridida, Spiriferida, Spiriferinida, and Terebratulida coming from the Guadalupian lower-middle part of the Pamuçak Formation at Çürük Dað, Antalya (Western Taurus, Turkey). Associated conodonts are also reported and illustrated. The brachiopod taxa are either pedicle attached genera, with one genus also stabilized by penetration of its elongate umbo, or free living concavo-convex semi-infaunal genera; this indicates that the energy of the environment was never very high, as in settings just below the fair weather wave-base or in a back-reef, more protected inner platform. The brachiopods from the Pamuçak Formation are very similar to the Wordian fauna of southeastern Oman, and they are similar to the Guadalupian assemblages of Chios, North Iran, South Thailand, and Salt Range. In comparison they share only a few taxa with the Guadalupian faunas of Central Afghanistan and Karakorum. Therefore the biotic affinity of the Guadalupian brachiopods of the Pamuçak Formation is clearly peri-Gondwanan. The brachiopod record at Çürük Dað has implications for understanding the pattern of the end-Guadalupian (pre-Lopingian) biotic crisis. The pre-Lopingian crisis assemblages are quite diverse and nearly totally consist of Guadalupian genera and species except for a single Lopingian incomer. Their stratigraphic range terminates rather abruptly and the following 120 metres of shallow water limestones are barren of brachiopods, after which there is the first occurrence of Lopingian brachiopod taxa, which show a much lower biodiversity.  This pattern is different from that observed in South China and it shows that the end-Guadalupian crisis is not only characterized by taxonomic selectivity, but also by a strong local control on the extinction/recovery pattern of some groups.

description: Multi-dimensional entangled states have been proven to be more powerful in some quantum information process. In this paper, down-converted photons from spontaneous parametric down conversion(SPDC) are used to engineer multi-dimensional entangled states. A kind of multi-degree multi-dimensional Greenberger-Horne-Zeilinger(GHZ) state can also be generated. The hyper-entangled photons, which are entangled in energy-time, polarization and orbital angular momentum (OAM), is proved to be useful to increase the dimension of systems and investigate higher-dimensional entangled states.

description: We show that the phase space of three-dimensional gravity contains two layers of dualities: between diffeomorphisms and a notion of "dual diffeomorphisms" on the one hand, and between first order curvature and torsion on the other hand. This is most elegantly revealed and understood when studying the most general Lorentz-invariant first order theory in connection and triad variables, described by the so-called Mielke-Baekler Lagrangian. By analyzing the quasi-local symmetries of this theory in the covariant phase space formalism, we show that in each sector of the torsion/curvature duality there exists a well-defined notion of dual diffeomorphism, which furthermore follows uniquely from the Sugawara construction. Together with the usual diffeomorphisms, these duals form at finite distance, without any boundary conditions, and for any sign of the cosmological constant, a centreless double Virasoro algebra which in the flat case reduces to the BMS$_3$ algebra. These algebras can then be centrally-extended via the twisted Sugawara construction. This shows that the celebrated results about asymptotic symmetry algebras are actually generic features of three-dimensional gravity at any finite distance. They are however only revealed when working in first order connection and triad variables, and a priori inaccessible from Chern-Simons theory. As a bonus, we study the second order equations of motion of the Mielke-Baekler model, as well as the on-shell Lagrangian. This reveals the duality between Riemannian metric and teleparallel gravity, and a new candidate theory for three-dimensional massive gravity which we call teleparallel topologically massive gravity.

description: The Transiting Exoplanet Survey Satellite (TESS) has now been operational for a little over two years, covering the Northern and the Southern hemispheres once. The TESS team processes the downlinked data using the Science Processing Operations Center pipeline and Quick Look pipeline to generate alerts for follow-up. Combined with other efforts from the community, over two thousand planet candidates have been found of which tens have been confirmed as planets. We present our pipeline, Nigraha, that is complementary to these approaches. Nigraha uses a combination of transit finding, supervised machine learning, and detailed vetting to identify with high confidence a few planet candidates that were missed by prior searches. In particular, we identify high signal to noise ratio (SNR) shallow transits that may represent more Earth-like planets. In the spirit of open data exploration we provide details of our pipeline, release our supervised machine learning model and code as open source, and make public the 38 candidates we have found in seven sectors. The model can easily be run on other sectors as is. As part of future work we outline ways to increase the yield by strengthening some of the steps where we have been conservative and discarded objects for lack of a datum or two.

description: Throughout its first part this paper deals with the legal interest as a fundamental element of admissibility as to exercise an administrative appeal during the administrative process. Two are the questions to be answered and they refer to cases in which legal interest actually exists and cases which lead to its loss. Relevantly, special forms of legal interest are listed, according to the subject of the administrative act and the legal good which the act affects. In the second part of the paper, the forms of petition in lines of communal and international law are compared to the administrative appeals foreseen by the Greek legislation and the similarity in the ways that the legal interest operates throughout the different legal systems is investigated.

description: The Y_0.5Ca_0.5BaCo_4O_7 compound exhibits four magnetic anomalies at the temperatures 387, 281, 52, and 14 K; all anomalies show characteristics typical for spin freezing into disordered states: frequency dependent transition temperature in the AC magnetic susceptibility together with relaxation of thermoremnant magnetization. Y_0.5Ca_0.5BaCo_4O_7 is a semiconductor with a small band-gap of 0.17 eV concluded from four-point conductivity measurements and the conductivity is proportional to T^(-3/4), suggesting an electron hopping mechanism involving Co^(2+) and Co^(3+) ions; at higher temperatures, double-exchange is the proposed reason for the strong magnetic interaction. At lower temperatures, super-exchange interactions start to compete with the double-exchange for domination and this competition together with geometrical frustrations in the structure are responsible for magnetic disorder down to 2 K. Covalence between Co and O is also discussed as additional reason for the strong magnetic interactions.

description: We investigate the renormalization group theory of generalized multi-vertex sine-Gordon model by employing the dimensional regularization method and also the Wilson renormalization group method. The vertex interaction is given by $\cos(k_j\cdot ϕ)$ where $k_j$ ($j=1,2,\cdots,M$) are momentum vectors and $ϕ$ is an $N$-component scalar field. The beta functions are calculated for the sine-Gordon model with multi cosine interactions. The second-order correction in the renormalization procedure is given by the two-point scattering amplitude for tachyon scattering. We show that new vertex interaction with momentum vector $k_{\ell}$ is generated from two vertex interactions with vectors $k_i$ and $k_j$ when $k_i$ and $k_j$ meet the condition $k_{\ell}=k_i\pm k_j$ called the triangle condition. Further condition $k_i\cdot k_j=\pm 1/2$ is required within the dimensional regularization method. The renormalization group equations form a set of closed equations when $\{k_j\}$ form an equilateral triangle for $N=2$ or a regular tetrahedron for $N=3$. The Wilsonian renormalization group method gives qualitatively the same result for beta functions.

description: At linear colliders, the e+e- luminosity is limited by beam-collision effects, which determine the required emittances of beams in damping rings (DRs). While in gamma-gamma collisions at the photon collider, these effects are absent, and so smaller emittances are desirable. In present damping rings designs, nominal DR parameters correspond to those required for e+e- collisions. In this note, I would like to stress once again that as soon as we plan the photon-collider mode of ILC operation, the damping-ring emittances are dictated by the photon-collider requirements--namely, they should be as small as possible. This can be achieved by adding more wigglers to the DRs; the incremental cost is easily justified by a considerable potential improvement of the gamma-gamma luminosity. No expert analysis exists as of yet, but it seems realistic to obtain a factor five increase of the gamma-gamma luminosity compared to the ``nominal'' DR design.

Working with peasants: reconsidering representations of the Maya
Creators: name: Porter, Wendy Lee
Publisher: name: University of British Columbia
Year: 2009

description: Claiming a post-1960 "revolution" in Maya studies, Mayanists have seemingly relegated the era between 1924 and 1960 (the culture-historical period in Americanist archaeology) to the methodological past, arguing that with the advent of the "New Archaeology" and substantial decipherment of the ancient Maya writing system, the misconceptions and misunderstandings of pre-1960's Mayanists have now been corrected. In reconsidering representations of the Maya produced between 1924 and 1960,1 investigate the origins and development of an objectivist model of the ancient Maya, the so-called "Morley-Thompson" model, that still persists despite both contradictory evidence in the archaeological record, and Mayanists'claims that the model has been abandoned. This study investigates the consequences of the intense and intimate interactions between Mayanists and Maya working together in the field. This interdependence of Mayanists and the Maya embodied the canonical model's inequitable distributions of power, and mirrored another layer of hierarchic power. I contend that Mayanists' interventions in pan-American identity formation explored the fears and desires of a U.S. middle class whose government sought to establish, then consolidate its economic and political hegemony in the hemisphere. I suggest that Mayanists' often ambiguous and even paradoxical representations, ostensibly of the ancient Maya, reflected ambivalence toward an indigenous group that appeared both extraordinarily like, and disturbingly unlike, popular conceptions of a U.S. national "character." I argue that Maya studies, beginning in 1924, developed a powerful trajectory based in ambiguous feelings of recognition, desire and fear of the American indigenous Other that was processed and articulated through Mayanists' representations. I argue, moreover, that the conditions that contributed to Mayanists' canonical claim for an ancient Maya class hierarchy also remain in force, embedded in Mayanists' motivations for the relationships they cultivate with the contemporary Maya when they undertake the work of representing the ancient Maya.

description: We show how phasing between tandem bioinspired fins flapping at high-stroke amplitudes modulates rear fin thrust production and wake characteristics. Load cell thrust measurements show that the rear fin generates 25% more thrust than the front fin when it lags the latter by a quarter cycle, and performs 8% worse when it leads the front fin by the same amount. The flow interactions between the fins responsible for these observations are analyzed using two-dimensional particle image velocimetry measurements and three-dimensional computational fluid dynamics simulations. Distributions of velocity elucidate variations in the effective flow induced on the rear fin for different phase offsets. Vortex structure interactions and particle rakes reveal the contributions of the leading- and trailing-edge vortices shed by the front fin in modulating the suction at the rear fin leading edge. Furthermore, the wake structure far downstream of the fins changes in its coherence, axial and radial extents for the different phase offsets. These findings are relevant for the design and performance optimization of various unmanned underwater vehicles that utilize such tandem systems.

description: In this graphic presentation, I summarize the main steps that led to the isolation and purification from human leukaemia cells of oncogenic microbial entities that share some of the concepts and features that apply to Mimiviruses infecting amoeba.

Like Mimiviruses, these human microbial agents have a gigantic size, a mega-genome and retain the Gram stain. However, distinct from environmental giant viruses, they display a unique mammalian retroviral nature, carry multiple oncogenes and induce tumours formation in mice, after three weeks post infection.

This human microorganism is not an archetypal oncogenic virus, with few proteins, but an infectious, self governing MICROBIAL CELL-LIKE ENTITY, with hundreds of proteins, carrying in its large mega-genome a transforming arsenal of multiple oncogenes.

We are facing a sort of small autonomous infectious cell, a simplified version of its eukaryotic counterparts, specialized in carcinogenesis.

The discovery of this microbial entity with an acute transformation mechanism and infecting humans suggests that the number of cancer of infectious origin would be even greater than what is supposed.

 This breakthrough might open the door to a preventive vaccine against cancer, offering the possibility to target an entire shuttling system of oncogenes and not just a solitary molecule involved in carcinogenesis.

description: We propose and test a fairly simple idea that could account for the blazar sequence: all jets are launched with similar energy per baryon, independently of their power. For instance, flat-spectrum radio quasars (FSRQs), the most powerful jets, manage to accelerate to high bulk Lorentz factor, as observed in the radio. As a result, the emission region will have a rather modest magnetization which will induce a steep particle spectra therein and a rather steep emission spectra in the gamma-rays; particularly in the \textit{Fermi}-LAT band. For the weaker jets, namely BL Lacertae objects (BL Lacs), the opposite holds true; i.e., the jet does not achieve a very high bulk Lorentz factor, leading to more magnetic energy available for non-thermal particle acceleration and harder emission spectra. Moreover, this model requires but a handful of parameters. By means of numerical simulations we have accomplished to reproduce the spectral energy distributions and light-curves from fiducial sources following the aforementioned model. With the a complete evolution of the broadband spectra we were able to study in detail the spectral features at any particular frequency band at any given stage. Finally numerical results are compared and contrasted with observations.

description: The properties of toroidal hyperheavy even-even nuclei and the role of toroidal shell structure are extensively studied within covariant density functional theory. The general trends in the evolution of toroidal shapes in the $Z\approx 130-180$ region of nuclear chart are established for the first time. These nuclei are stable with respect of breathing deformations. The most compact fat toroidal nuclei are located in the $Z\approx 136, N\approx 206$ region of nuclear chart, but thin toroidal nuclei become dominant with increasing proton number and on moving towards proton and neutron drip lines. The role of toroidal shell structure, its regularity, supershell structure, shell gaps as well as the role of different groups of the pairs of the orbitals in its formation are investigated in detail. The lowest in energy solutions at axial symmetry are characterized either by large shell gaps or low density of the single-particle states in the vicinity of the Fermi level in at least one of the subsystems (proton or neutron). Related quantum shell effects are expected to act against the instabilities in breathing and sausage deformations for these subsystems. The investigation with large set of covariant energy density functionals reveals that substantial proton $Z=154$ and 186 and neutron $N=228$, 308 and 406 spherical shell gaps exist in all functionals. The nuclei in the vicinity of the combination of these particle numbers form the islands of stability of spherical hyperheavy nuclei. The study suggests that the $N=210$ toroidal shell gap plays a substantial role in the stabilization of fat toroidal nuclei.

Οι επιγραφές της παλαιοχριστιστιανικής περιόδου εμφανίζουν διαφοροποιήσεις όσον αφορά στις μετρικές εφαρμογές που ακολουθούνται βάσει των οποίων μπορούν να ενταχθούν σε δύο ομάδες. Οι ομάδες αυτές αντιπροσωπεύουν δύο στάδια μιας εξελικτικής πορείας του τρόπου εφαρμογής του δακτυλικού εξαμέτρου. Στις επιγραφές που εντάσσουμε στην πρώτη ομάδα(4ος-τέλη 5ου αιώνα)παρατηρείται μεγάλη ελαστικότητα στις εφαρμογές του μετρικού συστήματος, αντίθετα με ότι συμβαίνει στις επιγραφές της δεύτερης ομάδας, όπου ακολουθούνται οι αυστηροί κανόνες που εισήγαγε στα τέλη του 5ου αιώνα ο Νούνος από την Πανόπολη.

description: The study of the use of the dactylic exametre has contributed to the definition of criteria on their dating methods. The palaeochristianic period inscriptions appear to differ regarding their metric applications. These differencies have led to the creation of two groups of inscriptions, which represent two stages in the evolutionary course of the first group(4th-late 5th century) we can observe a looser method of applying the metric system. On the contrary the inscriptions of the second group follow the strict tules that first Nonnos from Panopolis introduced during the last decades of the 5th century. There are no inscriptions composed during the 7th and the 8th century in dactylic verse. The use of this metre appears again in the 9th century and remains during the post byzantine period. Though, the evolutionary course has stopped, and most of today's existing examples of these periods are unsuccesful immitations of older patterns.

description: The interplay of nonclassical light and surface plasmons has attracted considerable attention due to fundamental interests and potential applications. To gain more insight into the quantum nature of the photon-surface-plasmon coupling, time-resolved detection of the interaction is invaluable. Here we demonstrate the time-resolved detection of photon-surface-plasmon coupling by exploiting single and entangled photons with long coherence time to excite single optical plasmons. We examine the nonclassical correlation between the single photons and single optical plasmons in such systems using the time-resolved Cauchy-Schwarz inequality. We also realize single optical plasmons with programmable temporal wavepacket by manipulating the waveform of incident single photons. The time-resolved detection and coherent control of single optical plasmons offer new opportunities to study and control the light-matter interaction at the nanoscale.

description: Saliency methods are used extensively to highlight the importance of input features in model predictions. These methods are mostly used in vision and language tasks, and their applications to time series data is relatively unexplored. In this paper, we set out to extensively compare the performance of various saliency-based interpretability methods across diverse neural architectures, including Recurrent Neural Network, Temporal Convolutional Networks, and Transformers in a new benchmark of synthetic time series data. We propose and report multiple metrics to empirically evaluate the performance of saliency methods for detecting feature importance over time using both precision (i.e., whether identified features contain meaningful signals) and recall (i.e., the number of features with signal identified as important). Through several experiments, we show that (i) in general, network architectures and saliency methods fail to reliably and accurately identify feature importance over time in time series data, (ii) this failure is mainly due to the conflation of time and feature domains, and (iii) the quality of saliency maps can be improved substantially by using our proposed two-step temporal saliency rescaling (TSR) approach that first calculates the importance of each time step before calculating the importance of each feature at a time step.

description: Η εισαγωγή των υπερήχων για την προπαρασκευή ανάστροφης κοιλότητας δημιούργησε νέα δεδομένα στην περιακρορριζική χειρουργική. Ο σκοπός της παρούσας ερευνητικής μελέτης είναι η in vitro αξιολόγηση τριών τεχνικών προπαρασκευής κοιλότητας για ανάστροφη έμφραξη. Χρησιμοποιήθηκαν 45 πρόσθια μονόριζα δόντια, άνω και κάτω γνάθου, ενδοδοντικά θεραπευμένα, τα οποία χωρίστηκαν σε τρεις ομάδες, των 15 δοντιών. Στην ομάδα Α οι προπαρασκευές πραγματοποιήθηκαν με στρογγύλη εγγλυφίδα Νο1 προσαρμοσμένη σε μικροχειρολαβή χαμηλών ταχυτήτων, στην ομάδα Β με ρύγχος υπερήχων ανοξείδωτου χάλυβα με διαμάντι στο κοπτικό άκρο και στην ομάδα Γ με ρύγχος υπερήχων ανοξείδωτου χάλυβα χωρίς διαμάντι στο κοπτικό άκρο. Η παρατήρηση έγινε με ηλεκτρονικό μικροσκόπιο σάρωσης (SEM) ύστερα από την δημιουργία αντιγράφων. Συγκρίθηκαν οι επιφάνειες των ακρορριζίων πριν και μετά την προπαρασκευή ανάστροφης κοιλότητας και αξιολογήθηκε ο αριθμός και το είδος των ρωγμών, η δημιουργία μικροανωμαλιών στα όρια των ανάστροφων κοιλοτήτων, καθώς και η επιφάνεια των εμφρακτικών υλικών μετά την εκτομή του ακρορριζικού τμήματος της ρίζας. Δεν βρέθηκαν στατιστικά σημαντικές διαφορές ανάμεσα στις τρεις τεχνικές, όσον αφορά τον αριθμό και το είδος των ρωγμών και των μικροανωμαλιών. Παρατηρήθηκαν μικροκενά ανάμεσα στα εμφρακτικά υλικά και τα τοιχώματα της οδοντίνης σε ορισμένα δείγματα.
description: The introduction of ultrasonics in root-end cavity preparation has brought new prospects in periapical surgery. The purpose of this study was the in vitro evaluation of three different root-end preparation techniques. 45 single-rooted anterior teeth, endodontically treated, were divided into three groups. Each group included 15 teeth. Group A was performed with a round bur No1 adapted in a slow-speed micro-handpiece, group B with a diamond-coated stainless steel ultrasonic tip and group C with a smooth stainless steel ultrasonic tip. Teeth were examined under scanning electron microscope (SEM) after replicas preparation of the specimens. The apical surfaces were compared before and after the root-end preparation. The number, the type of cracks and the marginal quality of the retrograde cavities were evaluated. The surface of root filling materials after root-end resection was also examined. There were no statistically significant differences in treatment results related to the number and the type of cracks, and the marginal chipping. Gaps were noted between the root filling materials and the walls of the root canal in few specimens.

description: The propagation by continuous time quantum walks (CTQWs) on one-dimensional lattices shows structures in the transition probabilities between different sites reminiscent of quantum carpets. For a system with periodic boundary conditions, we calculate the transition probabilities for a CTQW by diagonalizing the transfer matrix and by a Bloch function ansatz. Remarkably, the results obtained for the Bloch function ansatz can be related to results from (discrete) generalized coined quantum walks. Furthermore, we show that here the first revival time turns out to be larger than for quantum carpets.

description: We studied the period-K magnitude (P-K) relations of nearby Mira and Mira-like variables with relatively good Hipparcos parallaxes. They form at least two prominent sequences on the P-K plane, corresponding to the sequences C (Mira variables pulsating in the fundamental mode) and C'(Mira variables pulsating in the 1st overtone mode), that were found in the LMC. As a part of an ongoing study to see the differences between the Mira variables pulsating in the fundamental and the 1st overtone mode, we searched for SiO masers in the nearby variables on the sequences C' and C using the Nobeyama 45m radio telescope. We observed 28 selected nearby Mira and Mira-like variables without previous maser observations, and found 3 new emitters. The observational result shows that there is few or no SiO maser emitters pulsating in the 1st overtone mode.

description: Two structures in the all-particle energy spectrum of cosmic rays, the knee at 4 PeV and the second knee around 400 PeV are proposed to be explained by a phenomenological model, the poly gonato model, connecting direct and indirect measurements. Within this approach the knee is caused by a successive cut-off of the flux for individual elements starting with protons at 4.5 PeV. The second knee is interpreted as the end of the stable nuclei of the periodic table. To check some key features of this model calculations of the cosmic ray energy spectrum and the propagation path length at energies from 10^14 to 10^19 eV have been performed within the framework of a combined approach based on the diffusion model of cosmic rays and a direct simulation of charged-particle trajectories in the Galaxy.

description: Early wildfire detection is of paramount importance to avoid as much damage as possible to the environment, properties, and lives. Deep Learning (DL) models that can leverage both visible and infrared information have the potential to display state-of-the-art performance, with lower false-positive rates than existing techniques. However, most DL-based image fusion methods have not been evaluated in the domain of fire imagery. Additionally, to the best of our knowledge, no publicly available dataset contains visible-infrared fused fire images. There is a growing interest in DL-based image fusion techniques due to their reduced complexity. Due to the latter, we select three state-of-the-art, DL-based image fusion techniques and evaluate them for the specific task of fire image fusion. We compare the performance of these methods on selected metrics. Finally, we also present an extension to one of the said methods, that we called FIRe-GAN, that improves the generation of artificial infrared images and fused ones on selected metrics.

Comparison of structurally related peptides in their antimicrobial and anti-endotoxic activity
Creators: name: Gough Scott, Monisha
Publisher: name: University of British Columbia
Year: 2009

description: Sepsis, a serious problem in the developed world, is often associated with Gram negative bacteria. Their pathogenesis is in part related to the release of an outer membrane component, endotoxin. There is great interest in the development of an anti-endotoxin due to the lack of an effective therapy. In this study a series of α-helical cationic peptides, based on hybrids of the moth peptide cecropin and the bee peptide melittin was created using as the parent peptides, MBI-27 and MBI-28. MBI-27 and MBI-28 had already been shown to have antimicrobial and anti-endotoxin activity. From these two peptides along with CP26 and CP29 (more amphipathic in nature), a series of 31 variants with small amino acid changes were designed. The antimicrobial activity of the peptides was studied by MIC determination, killing assays and inner membrane permeabilization studies. The peptides were also tested for their ability to bind LPS and block production of IL-6 and TNF by LPS-stimulated macrophages. Changes made to the variant peptides did not improve upon the antimicrobial activity of MBI-28. Many of the peptides lost Gram-positive activity and some of the peptides lost all antimicrobial activity. The addition of Mg²+ had a partial inhibitory effect on the killing of E. coli and P. aeruginosa by CP26 and MBI-28 as well as inhibiting inner membrane permeabilization of E.coli by CP26. The peptides were found to be non-toxic to the macrophage cells under the conditions tested. The peptides were found to inhibit TNF production measured by the L cell assay (bio-active TNF) to a larger extent than that tested by ELISA, although the trends were generally the same. The peptide effect on IL-6 production was very similar to that seen with the TNF ELISA data. The peptides that were good antimicrobials and had high binding affinity for E.coli LPS also were able to inhibit production of IL-6 and TNF by LPS-stimulated macrophages. Some of the peptides that had no antimicrobial activity and higher LPS binding affinities were not as effective in preventing production of cytokines although this was not always the case. There are a large number of factors involved in what makes a good peptide; length and charge but not hydrophobicity of the peptides were found to play a role.

A multiwavelength study of the remnant of nova GK Persei

description: We present new observations of the nebular remnant of the old nova GK Persei 1901, in the optical using the 2m HCT and at low radio frequencies using the GMRT. The evolution of the nova remnant indicates shock interaction with the ambient medium, especially in the southwest quadrant. Application of a simple model for the shock and its evolution to determine the time dependence of the radius of the shell in the southwest quadrant indicates that the shell is now expanding into an ambient medium that has a lower density compared to the density of the ambient medium ahead of the shock in 1987.There are indications of a recent interaction of the nova remnant with the ambient medium in the northeast quadrant also. The nova remnant of GK Per is detected at all the observed radio frequencies and is of similar extent as the optical remnant. Putting together our radio observations with VLA archival data on GK Per from 1997, we obtain three interesting results: 1. The spectrum above 1.4 GHz follows a power law with an index -0.7 and below 1.4 GHz follows a power law with an index ~ -0.85. This could be due to the presence of at least two populations of electrons dominating the global emission at different frequencies. 2. We record an annual secular decrease of 2.1% in the flux density of the nova remnant at 1.4 and 4.9 GHz between 1984 and 1997 which has left the spectral index unchanged at -0.7. No such decrease is observed in the flux densities below 1 GHz. 3. We record an increase in the flux density at 0.33 GHz compared to the previous estimate in 1987. We conclude that the remnant of nova GK Per is similar to supernova remnants and in particular, to the young supernova remnant Cas A.

description: A specific concept of structural model is used as a background for discussing the structurality of its parameterization. Conditions for a structural model to be also causal are examined. Difficulties and pitfalls arising from the parameterization are analyzed. In particular, pitfalls when considering alternative parameterizations of a same model are shown to have lead to ungrounded conclusions in the literature.
Discussion of observationally equivalent models related to different economic mechanisms are used to make clear the connection between an economicall meaningful  parameterization and an economically meaningful decomposition of a complex model. The design of economic policy is used for drawing some practical implications of the proposed analysis.
title: К вопросу о методах изучения массовой литературы (анализируя эпизоды из романов А.Бушкова и П.Молитвина)

description: Предлагается метод анализа массовых текстов, основанный на сопоставлении коммерчески успешной и неуспешной массовой литературы. Для этого применяется сравнительный анализ сопоставимых эпизодов из успешных и провальных книг, построенных в одном жанровом каноне. Подобный анализ позволяет увидеть, как успешные массовые авторы усложняют текст, оставаясь в рамках тех же шаблонов, что и их конкуренты. В качестве иллюстрации метода приводится сопоставительный анализ эпизодов из романа А.А.Бушкова «Летающие острова» и романа П.В.Молитвина «Дорога дорог». Демонстрируется, что более успешный автор — Бушков — в отличие от конкурента, не доводит до предела героизацию героя; поддерживает более высокий событийный темп; в большей степени стимулирует воображение читателя; не «объясняет» читателю, какие эмоции нужно испытывать, а стремится вызвать их; а также усложняет саспенсовую структуру, синхронизируя время чтения со временем в изображенном мире. Представляется, подобный анализ позволяет увидеть, что коммерчески успешная массовая литература может быть сложно устроенной, но сложность эта кроется не в области, привычной для литературы первого ряда (сложная мотивная и философская система, эксперименты с формой и др.), но в области приемов, направленных на удержание читательского внимания в конкретный момент времени.
