The real Fatou conjecture (AM-144)

CERN Document Server

Graczyk, Jacek

2014-01-01

In 1920, Pierre Fatou expressed the conjecture that--except for special cases--all critical points of a rational map of the Riemann sphere tend to periodic orbits under iteration. This conjecture remains the main open problem in the dynamics of iterated maps. For the logistic family x- ax(1-x), it can be interpreted to mean that for a dense set of parameters ""a,"" an attracting periodic orbit exists. The same question appears naturally in science, where the logistic family is used to construct models in physics, ecology, and economics. In this book, Jacek Graczyk and Grzegorz Swiatek provi

Considering the quantum effects of diffraction and the collective screening effects, the potential of test charge in semiclassical plasmas is derived. It is generalized exponential screened Coulomb potential. Using the Ritz variational method incorporating this potential, the effects of semiclassical plasma on the energy levels and radiative transitions are investigated systematically, taking highly charged H-like ion as an example. The Debye plasma model is also employed for comparison purposes. Comparisons and analysis are made between these two sets of results and the differences are discussed.

Q and A. Poland's progress on the road to new nuclear

Energy Technology Data Exchange (ETDEWEB)

Kraev, Kamen [NucNet, Brussels (Belgium)

2017-06-15

Conflicting reports have emerged from Poland about plans for its first reactors. Professor Grzegorz Wrochna of the Polish National Centre for Nuclear Research says the programme is on track and a business model is expected soon. The previous government's programme calls for 6 GW in two locations. The government recently published a strategy for responsible development which calls for the nuclear programme to be sped up. However, no capacity figures were included. The industry should not be bound by a rigid number. In time, maybe we will speak of 4 GW or 12 GW, but it will depend on market needs and financial possibilities. The biggest risks do not come from cancellation or public opinion. They come from delays.

Continuous-Time Random Walk with multi-step memory: an application to market dynamics

Science.gov (United States)

Gubiec, Tomasz; Kutner, Ryszard

2017-11-01

An extended version of the Continuous-Time Random Walk (CTRW) model with memory is herein developed. This memory involves the dependence between arbitrary number of successive jumps of the process while waiting times between jumps are considered as i.i.d. random variables. This dependence was established analyzing empirical histograms for the stochastic process of a single share price on a market within the high frequency time scale. Then, it was justified theoretically by considering bid-ask bounce mechanism containing some delay characteristic for any double-auction market. Our model appeared exactly analytically solvable. Therefore, it enables a direct comparison of its predictions with their empirical counterparts, for instance, with empirical velocity autocorrelation function. Thus, the present research significantly extends capabilities of the CTRW formalism.

On the continuing relevance of Mandelbrot's non-ergodic fractional renewal models of 1963 to 1967

Watkins, Nicholas W.

2017-12-01

The problem of "1/f" noise has been with us for about a century. Because it is so often framed in Fourier spectral language, the most famous solutions have tended to be the stationary long range dependent (LRD) models such as Mandelbrot's fractional Gaussian noise. In view of the increasing importance to physics of non-ergodic fractional renewal models, and their links to the CTRW, I present preliminary results of my research into the history of Mandelbrot's very little known work in that area from 1963 to 1967. I speculate about how the lack of awareness of this work in the physics and statistics communities may have affected the development of complexity science, and I discuss the differences between the Hurst effect, "1/f" noise and LRD, concepts which are often treated as equivalent.

Optical oscillator strengths of the valence-shell excitations of atoms and molecules determined by the dipole ( γ,γ) method

The dipole (γ,γ) method, which is the inelastic X-ray scattering operated at a negligibly small momentum transfer, has been developed to determine the absolute optical oscillator strengths of the valence-shell excitations of atoms and molecules. This new method is free from the line saturation effect, and its Bethe-Born conversion factor varies much more slowly with the excitation energy than that of the dipole (e, e) method. Thus the dipole (γ,γ) method provides a reliable approach to obtain the benchmark optical oscillator strengths of the valence-shell excitations for gaseous atoms and molecules. In this paper, we give a review of the dipole (γ,γ) method and some recent measurements of absolute optical oscillator strengths of gaseous atoms and molecules.

1998-04-01

The significance of Kapuscinski's work lies partly in the way in which it juxtaposes and interrelates various modes, thereby challenging fixed, monologic ways of viewing events. As a result of this, his writing evades easy definitions and conclusive categorisation. Finally, one of the most striking aspects of Kapuscinki's work lies in the way in which it provides a dramatic reflection of the interface between the fantastic and reality and between the surreal, the postmodern and journalistic realism.

Saddlepoint approximation to the distribution of the total distance of the continuous time random walk

Science.gov (United States)

Gatto, Riccardo

2017-12-01

This article considers the random walk over Rp, with p ≥ 2, where a given particle starts at the origin and moves stepwise with uniformly distributed step directions and step lengths following a common distribution. Step directions and step lengths are independent. The case where the number of steps of the particle is fixed and the more general case where it follows an independent continuous time inhomogeneous counting process are considered. Saddlepoint approximations to the distribution of the distance from the position of the particle to the origin are provided. Despite the p-dimensional nature of the random walk, the computations of the saddlepoint approximations are one-dimensional and thus simple. Explicit formulae are derived with dimension p = 3: for uniformly and exponentially distributed step lengths, for fixed and for Poisson distributed number of steps. In these situations, the high accuracy of the saddlepoint approximations is illustrated by numerical comparisons with Monte Carlo simulation.

A fractional reaction-diffusion description of supply and demand

Science.gov (United States)

Benzaquen, Michael; Bouchaud, Jean-Philippe

2018-02-01

We suggest that the broad distribution of time scales in financial markets could be a crucial ingredient to reproduce realistic price dynamics in stylised Agent-Based Models. We propose a fractional reaction-diffusion model for the dynamics of latent liquidity in financial markets, where agents are very heterogeneous in terms of their characteristic frequencies. Several features of our model are amenable to an exact analytical treatment. We find in particular that the impact is a concave function of the transacted volume (aka the "square-root impact law"), as in the normal diffusion limit. However, the impact kernel decays as t-β with β = 1/2 in the diffusive case, which is inconsistent with market efficiency. In the sub-diffusive case the decay exponent β takes any value in [0, 1/2], and can be tuned to match the empirical value β ≈ 1/4. Numerical simulations confirm our theoretical results. Several extensions of the model are suggested.

MCDF calculations of Auger cascade processes

Science.gov (United States)

Beerwerth, Randolf; Fritzsche, Stephan

2017-10-01

We model the multiple ionization of near-neutral core-excited atoms where a cascade of Auger processes leads to the emission of several electrons. We utilize the multiconfiguration Dirac-Fock (MCDF) method to generate approximate wave functions for all fine-structure levels and to account for all decays between them. This approach allows to compute electron spectra, the population of final-states and ion yields, that are accessible in many experiments. Furthermore, our approach is based on the configuration interaction method. A careful treatment of correlation between electronic configurations enables one to model three-electron processes such as an Auger decay that is accompanied by an additional shake-up transition. Here, this model is applied to the triple ionization of atomic cadmium, where we show that the decay of inner-shell 4p holes to triply-charged final states is purely due to the shake-up transition of valence 5s electrons.

Along the German Autobahnen, a truck carrying 20 tonnes of copper is on its way to Poland. The metal has already made a short tour of Europe, yet the drive across the high-speed highway is only the beginning of its transformation into CERN’s next linear accelerator, LINAC4.   Grzegorz Wrochna (left), director of the Andrzej Soltan Institute for Nuclear Studies (IPJ), and Rolf Heuer (right), CERN DG, sign the framework agreement between the two institutes. By the summer of 2012, the PI-Mode Structures (PIMS) will be constructed and completely installed in the LINAC4 tunnel. The PIMS cavities are the final accelerating structures needed for LINAC4, and have been designed to accelerate protons from 100 to 160MeV. While the first cavity was built entirely at CERN, construction of the remaining cavities has become a larger, multi-national operation.

Asymptotic densities from the modified Montroll-Weiss equation for coupled CTRWs

Aghion, Erez; Kessler, David A.; Barkai, Eli

2018-01-01

We examine the bi-scaling behavior of Lévy walks with nonlinear coupling, where χ, the particle displacement during each step, is coupled to the duration of the step, τ, by χ τβ. An example of such a process is regular Lévy walks, where β = 1. In recent years such processes were shown to be highly useful for analysis of a class of Langevin dynamics, in particular a system of Sisyphus laser-cooled atoms in an optical lattice, where β = 3/2. We discuss the well-known decoupling approximation used to describe the central part of the particles' position distribution, and use the recently introduced infinite-covariant density approach to study the large fluctuations. Since the density of the step displacements is fat-tailed, the last travel event must be treated with care for the latter. This effect requires a modification of the Montroll-Weiss equation, an equation which has proved important for the analysis of many microscopic models.

The Spanish mysticism in paintings by artists from the Fine Arts Academy in Krakow at the turn of the 21st century

Full Text Available During the last two decades the works of teachers from the Painting Department of the Academy of Fine Arts in Krakow: Grzegorz Bednarski, Katarzyna Makieła-Organisty, Janusz Matuszewski, Mirosław Sikorski, Edyta Sobieraj, Zbigniew Sprycha or Wojciech Szybist reveal traces of inspiration by the Spanish Golden Age. In this respect, paintings by Krakow artists stand out against other works of contemporary art both in Poland and globally. Their art should be discussed in the context of early modern meditatio mortis and tenebristic „baroqueism”, to which the artists themselves readily admit. The point of departure (frequently referred to as homage are mystic visions, portraits by El Greco, Francisco de Zurbarán’s bodegóns or eschatological „death hieroglyphics” by Juan de Valdés Léal. References to works by the Iberian masters are accompanied by links to Carmelite writings or Jesuit mystics. Formal and ideological analysis also allows us to ask a question of the possibility of presenting the „mystic theology” described by St. Theresa of the Infant Jesus, St. John of the Cross or St. Ignatius of Loyola in contemporary religious paintings.

A trend of steady decline in gastric cancer incidence rates is the effect of the increased standards of hygiene, conscious nutrition, and Helicobacter pylori eradication, which together constitute primary prevention. Avoidance of gastric cancer remains a priority. However, patients with higher risk should be screened for early detection and chemoprevention. Surgical resection enhanced by standardized lymphadenectomy remains the gold standard in gastric cancer therapy. This review briefly summarizes the most important aspects of gastric cancers, which include epidemiology, risk factors, classification, diagnosis, prevention, and treatment. The paper is mostly addressed to physicians who are interested in updating the state of art concerning gastric carcinoma from easily accessible and credible source.

Deformed barchans under alternating flows: Flume experiments and comparison with barchan dunes within Proctor Crater, Mars

Taniguchi, Keisuke; Endo, Noritaka

2007-10-01

It is generally considered that barchans, isolated crescentic-shaped dunes, develop where wind is unidirectional and the available sand is insufficient to cover the entire dune field; however, Bishop [Bishop, M.A., 2001. Seasonal variation of crescentic dune morphology and morphometry, Strzelecki Simpson desert, Australia. Earth Surface Process and Landforms 26, 783 791.] observed barchans that developed in areas where winds blow seasonally in opposite directions and described a peculiar deformation feature, the “rear slipface,” that is not found in ordinary barchans. Barchans under such bidirectional flows are poorly understood, and it is necessary to study barchans that formed under many different flow conditions. We conducted flume experiments to investigate the deformation of barchans under alternating water flow, and observed new deformation features in addition to rear slipfaces. We conclude that the deformation of barchans can be categorized into four types, one of which shows morphologies similar to barchans within Proctor Crater, Mars. The deformation type depends on the strength of the reverse flow relative to the forward flow and the absolute velocity of the forward flow. Comparison of our results with barchan dunes within Proctor Crater enable us to qualitatively estimate the wind strength and direction related to dune formation on Mars. These results are in agreement with those of Fenton et al. [Fenton, L.K., Toigo, A.D., Richardson, M.I., 2005. Aeolian processes in Proctor Crater on Mars: Mesoscale modeling of dune-forming winds.

In this article, we describe a case of a 34-year-old woman with diagnosis of schizophrenia with persistent moderate negative and cognitive symptoms, a participant of the Polish Sarcosine Study (PULSAR treated with olanzapine (25 mg per day and venlafaxine (75 mg per day. During ten weeks of sarcosine administration (2 g per day the patient’s activity and mood improved, but in the following 2 weeks, the patient reported decreased need for sleep, elevated mood, libido and general activity. We diagnosed drug-induced hypomania and recommended decreasing the daily dose of venlafaxine to 37.5 mg per day, which resulted in normalization of mood and activity in about 1 week. After this change, activity and mood remained stable and better than before adding sarcosine, and subsequent depressive symptoms were not noted. We describe here the second case report where sarcosine induced important affect changes when added to antidepressive and antipsychotic treatment, which supports the hypothesis of clinically important glutamate–serotonin interaction.Keywords: MNDA receptor, glutamatergic system, serotoninergic system

Dysfunction of the glutamatergic system plays an important role in the pathogenesis of schizophrenia. Therefore, glutamatergic agents such as N-methyl-D-aspartate receptor co-agonists (ie, glycine, D-cycloserine and glycine transporter type 1 inhibitors (eg, sarcosine are studied for their efficacy in ameliorating negative and cognitive symptomatology in patients with schizophrenia. We report the case of a 23-year-old schizophrenic patient treated with quetiapine and citalopram, who was offered concomitant sarcosine treatment. After obtaining an informed consent, we started administration of 2 g of sarcosine per day to treat persistent negative and cognitive symptoms. The patient's activity and mood improved within 2 weeks, but in the following 2 weeks the patient reported increased drive, activity, libido, unpleasant inner tension, and irritability. We ruled out hypomania and decided to decrease the daily dose of sarcosine to 1 g, which resulted in reduction of drive and irritability. Activity and mood improved compared with his state before adding sarcosine. We suggest a sarcosine dose between 1 g and 2 g per day with an initial dose of 2 g, but if side effects occur, the dose should be decreased to 1 g per day. We would like to emphasize the clinically important glutamate-serotonin interaction during concomitant use of sarcosine, citalopram, and quetiapine in our patient, which may lead to serious discomfort.Keywords: schizophrenia, glutamatergic system, serotoninergic system, sarcosine, NMDA receptor, dose finding

We have constructed a collisional-radiative (CR) model for W27+ ions including 226 configurations with n ≤ 9 and ł ≤ 5 for spectroscopic diagnostics. We newly include recombination processes in the model and this is the first result of extreme ultraviolet spectrum calculated for recombining plasma component. Calculated spectra in 40-70 Å range in ionizing and recombining plasma components show similar 3 strong lines and 1 line weak in recombining plasma component at 45-50 Å and many weak lines at 50-65 Å for both components. Recombination processes do not contribute much to the spectrum at around 60 Å for W27+ ion. Dielectronic satellite lines are also minor contribution to the spectrum of recombining plasma component. Dielectronic recombination (DR) rate coefficient from W28+ to W27+ ions is also calculated with the same atomic data in the CR model. We found that larger set of energy levels including many autoionizing states gave larger DR rate coefficients but our rate agree within factor 6 with other works at electron temperature around 1 keV in which W27+ and W28+ ions are usually observed in plasmas.

Direct and inverse problems in dispersive time-of-flight photocurrent revisited

2017-10-01

Using the fact that the continuous time random walk (CTRW) scheme is a random process subordinated to a simple random walk under the operational time given by the number of steps taken by the walker up to a given time, we revisit the problem of strongly dispersive transport in disordered media, which first lead Scher and Montroll to introducing the power law waiting time distributions. Using a subordination approach permits to disentangle the complexity of the problem, separating the solution of the boundary value problem (which is solved on the level of normal diffusive transport) from the influence of the waiting times, which allows for the solution of the direct problem in the whole time domain (including short times, out of reach of the initial approach), and simplifying strongly the analysis of the inverse problem. This analysis shows that the current traces do not contain information sufficient for unique restoration of the waiting time probability densities, but define a single-parametric family of functions that can be restored, all leading to the same photocurrent forms. The members of the family have the power-law tails which differ only by a prefactor, but may look astonishingly different at their body. The same applies to the multiple trapping model, mathematically equivalent to a special limiting case of CTRW.

Using the Monte Carlo simulation, we investigate a memory-impaired self-avoiding walk on a square lattice in which a random walker marks each of sites visited with a given probability p and makes a random walk avoiding the marked sites. Namely, p = 0 and p = 1 correspond to the simple random walk and the self-avoiding walk, respectively. When p> 0, there is a finite probability that the walker is trapped. We show that the trap time distribution can well be fitted by Stacy's Weibull distribution b(a/b){a+1}/{b}[Γ({a+1}/{b})]-1x^a\\exp(-a/bx^b)} where a and b are fitting parameters depending on p. We also find that the mean trap time diverges at p = 0 as p- α with α = 1.89. In order to produce sufficient number of long walks, we exploit the pivot algorithm and obtain the mean square displacement and its Flory exponent ν(p) as functions of p. We find that the exponent determined for 1000 step walks interpolates both limits ν(0) for the simple random walk and ν(1) for the self-avoiding walk as [ ν(p) - ν(0) ] / [ ν(1) - ν(0) ] = pβ with β = 0.388 when p ≪ 0.1 and β = 0.0822 when p ≫ 0.1.

Both endorphins excess and deficiency were postulated. CGRP is probably involved in dopaminergic transmission. The aim of this study was the evaluation of beta-endorphin (BE and CGRP blood concentrations before and after treatment of severe schizophrenia. Methods: Seventy patients treated with various antipsychotics, with severe symptoms of schizophrenia (51 with positive symptoms, 19 with negative symptoms, 15 first-degree relatives, and 44 healthy controls were included in the study. BE and CGRP blood concentrations were measured during patients severe schizophrenia and in their stable mental state after treatment. The results were compared with relatives and controls. Results: BE and CGRP concentrations in patients with negative symptoms were higher than in relatives and in controls. BE levels in patients with positive symptoms were lower than in patients with negative symptoms (P<0.0000 and controls (P<0.0006. No significant changes in CGRP concentration were found in patient samples. CGRP levels in these samples were independent of treatment, but they were significantly higher than in relatives and controls. After the treatment, BE level decreased in patients with negative symptoms (P<0.0001 and increased in patients with positive symptoms (P<0.0000. No differences in BE concentration between patients in stable mental state, their relatives, and controls were found. Conclusion: Effective antipsychotic treatment results in “normalization” of BE level. Specific changes in BE concentration could be involved in dopaminergic transmission and related to some symptoms of schizophrenia. Keywords

Full Text Available Phantasm of the Righteous and Agnieszka Holland’s film "In Darkness" The text analyses Agnieszka Holland’s film In Darkness against the background of the Polish discourse on the Righteous. The devices of this discourse are reconstructed on the basis of two documentary films: The Righteous by Ryszard Gontarz and Janusz Kidawa (1968 and The Story of the Kowalski by Arkadiusz Gołębiowski and Maciej Pawlicki (2009. The basic devices distinguished in the narrative of the Righteous are the following: 1. a symmetry between the Jewish and Polish suffering 2. lack of Jews’ gratefulness and solidarity (“we demonstrated solidarity as far as the sacrifice of life but they…”; 3. treating the Righteous as pars pro toto of the community (they become the proof of the “national character” of Poles; the motif of “the Righteous-anti-Semite”; 4. a conviction about Polish helplessness; 5. marginalisation of the Polish aggression against Jews (a viewpoint that apparently “the scum is everywhere” and the simultaneously expressed accusations that the victims were involved in the Holocaust themselves. Holland is not aware of the discursive mechanisms accumulating around the undertaken subject or the correlated stakes of the common imagination. Therefore, many fragments of In Darkness easily succumb to being captured by the prevailing, and in fact anti-Semitic, clichés of understanding the history. In effect, the phenomenon of unwanted comeback of phantasms occurs in reference to a narrative developed as an antidote for such.

“The Word for Mercy” in the Church Slavonic Translation of the Second Half of the 17th Century and Its Polish Original: Realia Interpretation

Tatiana V. Pentkovskaya

2017-12-01

Full Text Available “The Word for Mercy” was considered to be an original essay, written by Epiphanius Slavinetsky or Euthymius Chudovsky. In fact, it is a translation of Piotr Skarga’s cognominal sermon. The Church Slavonic translation is an example of the so-called inter-confessional rendering of the Polish original that shows its adaptation to the Orthodox tradition and to Russian historical and cultural specificity. The present paper analyses the problems of realia interpretation in the Church Slavonic translation of the Polish source. A distinctive feature of the translation is the elimination of specific signs of the Polish origin of the text. The translator pretends that a translated text is an original composition. To achieve this goal, he changes or omits the names of the Western saints. As markers indicating its place within the Byzantine tradition, he uses Greek lexical borrowings. Making a choice between lexical equivalents for transmission of the foreign realia, the translator probably uses multilingual lexicons such as the Thesaurus Polono-Latino-Graecus by Grzegorz Knapiusz and the Trilingual Lexicon by Epiphanius Slavinetsky. Very similar methods characterize the works of Simeon of Polotsk. Thus, it was not only the practice of the Chudov Monastery bookmen, but also Muscovite prevailing practice. “The Word for Mercy” is a unique example of adaptation of the Western ideas of state charity to the Russian situation in the second half of the 17th century. The ideological changes in the translation give this sermon features of the socio-legal project that is the hallmark of Early Modern times.

Pan Kiehot Güntera Grassa w serii przekładowej. Naśladowanie, wyobraźnia, tłumaczenie

Full Text Available Pan Kiehot by Günter Grass is one of many literary incarnations of Cervantes’s Don Quijote. Grass created his hero in a double manner: the character exists in the poem Pan Kiehot, published in Gleisdreieck in 1960, and a fragment of a chapter in The Tin Drum, the novel published in 1959. The poem has been translated six times into Polish, by Jan Koprowski, Krzysztof Karasek, Bolesław Fac, Zdzisław Jaskuła, Wojciech Woźniak and Ryszard Sobieszczański, whereas The Tin Drum, only once, by Sławomir Błaut. The article analyses all the translations into Polish, as well as the translation into Kashubian by Jan Trepczyk, in the context of the notion of translation series and textualisation series, proposed by Marta Skwara, and with reference to theorists of quixotism, such as Arne Melberg, Josè Ortega y Gasset and Michel Foucault, as well as to German and Polish critics of Grass’s work. The author draws conclusions about the challenge of a different form of interpretation, multiplied interpretation, which is facing the reader of a translation or textualisation series. Every translator who works on a text that has been translated before, must face various anxieties: “the anxiety of influence”, which is often coupled by horror vacui, and fear of imperfect rendition of source-texts meanings (as described by Jerzy Jarniewicz. Thanks to translation series, and works that constitute textualisation series together with translations, Grass’s Pan Kiehot is inscribed in entirely new interpretative framework: each new translation, thus, constitutes a challenge for the translator and for the imagination of a reader of the series.

Two new genera and five new species of Mugadina-like small grass cicadas (Hemiptera: Cicadidae: Cicadettini) from Central and Eastern Australia: comparative morphology, songs, behaviour and distributions.

Moulds (2012) established the genus Mugadina for two small cicadas, M. marshalli (Distant) and M. emma (Goding and Froggatt), both grass inhabiting species known from Queensland and New South Wales. Both species are notable for their relatively simple 'ticking' songs. Moulds further noted that there were at least two superficially similar genera of cicadas, but each with different genitalia. This paper describes two new genera of small (9-15 mm body lengths) and distinctive grass cicadas with genitalia that are very similar to those of Mugadina, but possess clear morphological, colour and calling song differences. The new genera are: Heremusina n. gen. with two known species namely H. udeoecetes n. sp. and H. pipatio n. sp.; the second new genus is Xeropsalta n. gen., containing four known species, X. thomsoni n. sp., X. aridula n. sp., X. rattrayi n. sp., and X. festiva n. comb. Heremusina n. gen. species are described from the Alice Springs area of Northern Territory and the Cloncurry area of northwest Queensland, from arid to semi arid habitats. The Xeropsalta n. gen. species are described from western, southwest and central Queensland, and from the Simpson and Strzelecki Deserts in northeastern South Australia and northwestern New South Wales, respectively, all locations in very arid to arid habitats, but close to seasonal (often irregular) rivers and lakes. X. festiva n. comb. occurs in semi arid habitats in southern and southeastern Australia.        Detailed taxonomic descriptions are provided of the new species, together with distributions, habitats, and the calling songs. The Heremusina species emit songs with short repetitive buzzing echemes, the echeme durations differing between each species. The Xeropsalta songs are notable for their complexity, containing multiple elements with rapid changes of amplitudes and temporal structures, rather atypical of the songs of most small grass dwelling cicadas.

Theropod Fauna from Southern Australia Indicates High Polar Diversity and Climate-Driven Dinosaur Provinciality

Benson, Roger B. J.; Rich, Thomas H.; Vickers-Rich, Patricia; Hall, Mike

2012-01-01

The Early Cretaceous fauna of Victoria, Australia, provides unique data on the composition of high latitude southern hemisphere dinosaurs. We describe and review theropod dinosaur postcranial remains from the Aptian–Albian Otway and Strzelecki groups, based on at least 37 isolated bones, and more than 90 teeth from the Flat Rocks locality. Several specimens of medium- and large-bodied individuals (estimated up to ∼8.5 metres long) represent allosauroids. Tyrannosauroids are represented by elements indicating medium body sizes (∼3 metres long), likely including the holotype femur of Timimus hermani, and a single cervical vertebra represents a juvenile spinosaurid. Single specimens representing medium- and small-bodied theropods may be referrable to Ceratosauria, Ornithomimosauria, a basal coelurosaur, and at least three taxa within Maniraptora. Thus, nine theropod taxa may have been present. Alternatively, four distinct dorsal vertebrae indicate a minimum of four taxa. However, because most taxa are known from single bones, it is likely that small-bodied theropod diversity remains underestimated. The high abundance of allosauroids and basal coelurosaurs (including tyrannosauroids and possibly ornithomimosaurs), and the relative rarity of ceratosaurs, is strikingly dissimilar to penecontemporaneous dinosaur faunas of Africa and South America, which represent an arid, lower-latitude biome. Similarities between dinosaur faunas of Victoria and the northern continents concern the proportional representatation of higher clades, and may result from the prevailing temperate–polar climate of Australia, especially at high latitudes in Victoria, which is similar to the predominant warm–temperate climate of Laurasia, but distinct from the arid climate zone that covered extensive areas of Gondwana. Most dinosaur groups probably attained a near-cosmopolitan distribution in the Jurassic, prior to fragmentation of the Pangaean supercontinent, and some aspects of the

Design and development of the ITER divertor VUV spectrometer have been performed from the year 1998, and it is planned to be installed in the year 2027. Currently, the design of the ITER divertor VUV spectrometer is in the phase of detail design. It is optimized for monitoring of chord-integrated VUV signals from divertor plasmas, chosen to contain representative lines emission from the tungsten as the divertor material, and other impurities. Impurity emission from overall divertor plasmas is collimated through the relay optics onto the entrance slit of a VUV spectrometer with working wavelength range of 14.6-32 nm. To validate the design of the ITER divertor VUV spectrometer, two sets of VUV spectrometers have been developed and tested at KSTAR tokamak. One set of spectrometer without the field mirror employs a survey spectrometer with the wavelength ranging from 14.6 nm to 32 nm, and it provides the same optical specification as the spectrometer part of the ITER divertor VUV spectrometer system. The other spectrometer with the wavelength range of 5-25 nm consists of a commercial spectrometer with a concave grating, and the relay mirrors with the same geometry as the relay mirrors of the ITER divertor VUV spectrometer. From test of these prototypes, alignment method using backward laser illumination could be verified. To validate the feasibility of tungsten emission measurement, furthermore, the tungsten powder was injected in KSTAR plasmas, and the preliminary result could be obtained successfully with regard to the evaluation of photon throughput.

Bambino covers the years 1945–1981, but also contains flashbacksto pre-war memory of Stettin and to the suppressed experiences of the new post-war inhabitants, as well as ‘flash-forwards’ to post-1989, post-communist reality; Ku słońcu covers 1981 to the first decade of 2000s. It will show how the novels portray these transformations through the experience primarily of women (but not only — in Bambino, through the main protagonists: Ula (formerly Ulrike, Anna and Marysia, and through that of the hidden narrator Magda (Marysia’s daughter born in the same year as the author, Iwasiów, 1963; and in Ku słońcu, primarily through the experience of Magda herself, as well as through that of two generations of ‘feminist’ academics: Małgorzata and Sylwia (in which it is hard not to perceive the personal experience of the author, though she is at pains to emphasize elsewhere that her work is a collective biography of the city, not so much of herself. The analysis follows Katarzyna Chmielewska’s supposition that contemporary Polish fiction dealing with the past ‘constantly oscillates between memory and genealogy’, and that it raises raw issues not yet addressed by historians; it also derives inspiration from the new ‘postdependency’ studiesproposed by Hanna Gosk and Ryszard Nycz. It also attempts to capture the specific nature of Iwasiów’s use of language, her style of feminism, her method of portraying place, and the connections in her prose between place and memory.

The purpose of this case study was to document the evolution of the gait pattern of a child with severe ITW using the Gillette Gait Index before and after the third and sixth weeks, a nonsurgical treatment program and then every 3 months to 1 year from the start of the treatment. This is significant because the case study shows that a nonsurgical treatment program can be an alternative treatment method for children with severe ITW.Case description: The case study involved a 5-year-old boy diagnosed with severe ITW. An orthopedist recommended a surgical treatment, but his parents refused to provide consent.Intervention: The subject participated in a 12-week nonsurgical treatment program that used tone-inhibiting casts (TICs combined with physiotherapy based on neurodevelopmental treatment principles. The treatment protocol included the following: 1 precast preparation; 2 TICs with treatment; and 3 post-cast treatment to improve the gait pattern.Outcomes: After treatment with TICs, the range of motion of ankle dorsiflexion during stance had increased, resulting in an almost normalized gait. The patient stopped toe walking for at least 1 year.Discussion: This study demonstrates that nonsurgical treatment should be considered first, with surgical options reserved for resistant cases; however, further research is required given the current lack of knowledge

The heavy solid line shows ULXs with black-hole accretors, the dashed line ULXs with neutron-star accretors, and the solid line the total. [Wiktorowicz et al. 2017]No Exotic Objects NeededWiktorowicz and collaborators performed a massive suite of simulations made possible by donated computer time from the Universe@Home project to examine how 20 million binary systems evolve into X-ray binaries. They then determined the number and nature of the ones that could appear as ULXs to us. The authors results show that the vast majority of the observed population of ULXs can be accounted for with super-Eddington compact binaries, without needing to invoke intermediate-mass black holes.Wiktorowicz and collaborators demonstrate that in environments with short star-formation bursts, black-hole accretors are the most common ULX source in the early periods after the burst, but neutron-star accretors dominate the ULX population after a few 100 Myr. In the case of prolonged and continuous star formation, neutron-star accretors dominate ULXs if the environment is solar metallicity, whereas black-hole accretors dominate in low-metallicity environments.The authors results present very clear and testable relations between the companion and donor star evolutionary stage and the age of the system, which we will hopefully be able to use to test this model with future observations of ULXs.CitationGrzegorz Wiktorowicz et al 2017 Ap

In one patient, mild pruritus was observed. Oxycodone did not evoke other AEs. Plasma concentrations of oxycodone while preserving analgesia were >2.9 ng/mL. Noroxycodone concentrations in plasma did not guarantee analgesic effect.Conclusion: The administration of epidural oxycodone at a dose of 5 mg prolongs the analgesia period to ~10 hours in patients after THA. Oxycodone may evoke pruritus. A 5 mg dose of oxycodone hydrochloride used in an epidural blockade seems to be a safe drug in patients

However, the benefits of an additional computed tomography (aCT performed over the next days after iv-thrombolysis have not been determined.Methods: We retrospectively screened 287 Caucasian patients with ischemic stroke who were consecutively treated with iv-thrombolysis from 2008 to 2012. The results of computed tomography performed on the second (control computed tomography and seventh (aCT day after iv-thrombolysis were compared in 274 patients (95.5%; 13 subjects (4.5%, who died before the seventh day from admission were excluded from the analysis.Results: aCTs revealed a higher incidence of HT than control computed tomographies (14.2% vs 6.6%; P=0.003. Patients with HT in aCT showed higher median of National Institutes of Health Stroke Scale score on admission than those without HT (13.0 vs 10.0; P=0.01 and higher presence of ischemic changes >1/3 middle cerebral artery territory (66.7% vs 35.2%; P<0.01. Correlations between presence of HT in aCT and National Institutes of Health Stroke Scale score on admission (rpbi 0.15; P<0.01, and the ischemic changes >1/3 middle cerebral artery (phi=0.03 existed, and the presence of HT in aCT was associated with 3-month mortality (phi=0.03.Conclusion: aCT after iv-thrombolysis enables higher detection of HT, which is related to higher 3-month mortality. Thus, patients with severe middle cerebral artery infarction may benefit from aCT in the decision-making process on the secondary prophylaxis. Keywords: ischemic stroke, iv

This paper presents coadministration of local anesthetic (LA via paravertebral blockade (PVB as the alternative to an unsuccessful subcutaneous fentanyl pain control in a 71-year old cancer patient with pathological fracture of femoral neck, bone metastases, and contraindications to morphine. Bupivacaine in continuous infusion (0.25%, 5 mL · hour-1 or in boluses (10 mL of 0.125%–0.5% solution, used for lumbar PVB, resulted in pain relief, decreased demand for opioids, and led to better social interactions. The factors contributing to an increased risk of systemic toxicity from LA in the patient were: renal impairment; heart failure; hypoalbuminemia; hypocalcemia; and a complex therapy with possible drug–drug interactions. These factors were taken into consideration during treatment. Bupivacaine’s side effects were absent. Coadministered drugs could mask LA’s toxicity. Elevated plasma α1-acid glycoprotein levels were a protective factor. To evaluate the benefit-risk ratio of the PVB treatment in boluses and in constant infusion, bupivacaine serum levels were determined and the drug plasma half-lives were calculated. Bupivacaine’s elimination was slower when administered in constant infusion than in boluses (t½ = 7.80 hours versus 2.64 hours. Total drug serum concentrations remained within the safe

Patients and methods: The study was a multicenter, randomized, double-blind, and placebo-controlled trial. Altogether, 376 women were assessed for eligibility, and signed informed consent. One hundred and sixty eligible women with abnormal, also called intermediate, vaginal microflora, as indicated by a Nugent score of 4–6 and pH >4.5 and zero or low Lactobacillus count, were randomized. Each participant was examined four times during the study. Women were randomly allocated to receive either the probiotic preparation inVag®, or a placebo (one capsule for seven consecutive days vaginally. The product inVag includes the probiotic strains Lactobacillus fermentum 57A, Lactobacillus plantarum 57B, and Lactobacillus gasseri 57C. We took vaginal swabs during visits I, III, and IV to determine the presence and abundance of bacteria from the Lactobacillus genus, measure the pH, and estimate the Nugent score. Drug safety evaluation was based on analysis of the types and occurrence of adverse events. Results: Administration of inVag contributed to a significant decrease (between visits in both vaginal pH (P<0.05 and Nugent score (P<0.05, and a significant increase in the abundance of Lactobacillus between visit I and visits III and IV (P<0.05.

The aim of our research was to analyze nutritional behaviors for the assessment of the risk of orthorexia. The authors developed a questionnaire in which 981 respondents participated and used it as a research method. Both men and women ate mostly 4–5 meals per day (46.30% women versus 34.74% men; however, more men than women ate 1–2 meals daily (18.95% men versus 7.9% women. Both place of birth and field of study did not differ in terms of the number of meals. Moreover, it was observed that the number of meals per day was correlated with the declared time spent on planning a diet. People who ate over 3 meals per day more often indicates that they spent >3 h per day on planning their diet in comparison with people who ate only 1–2 meals. Only 17.6% of the respondents declared that they most often ate meals in a company of someone, whereas 45.3% indicated that there was no rule. The remaining 37.1% of the respondents most often consumed their meals alone. Almost twice as many men as women never paid attention to the qualitative composition of nutrition. Women followed a slimming diet more often than men (20.3% versus 5.8% and this indicated >4 attempts of losing weight

Successful management of severe cancer pain may require invasive treatment. However, a patient's refusal of an invasive procedure necessitates that clinicians consider alternative options. Objective: Intrathecal bupivacaine delivery as a viable treatment of intractable pain is well documented. There are no data on rectal bupivacaine use in cancer patients or in the treatment of cancer tenesmoid pain. This study aims to demonstrate that bupivacaine administered rectally could be a step in between the current treatment options for intractable cancer pain (conventional/conservative analgesia or invasive procedures, and to evaluate the effect of the mode of administration (intrathecal versus rectal on the bupivacaine plasma concentration.Cases: We present two Caucasian, elderly inpatients admitted to hospice due to intractable rectal/tenesmoid pain.

A short intensive course in pottery handcraft was also offered to us in the Skansen. Hiking in the rocky labyrinth of Szczeliniec (please try to pronounce this name describing a magnificent cliffed hill with creviced rocks) was also a great adventure. This was followed by a ride on the serpentine Road of a Hundred Turns. And there was another event strongly supported by the local authorities. Two special tutorials on energy research and fusion for young scholars and the general public attracted nearly 200 people. The School was financially supported by the International Centre for Dense Magnetised Plasmas at IPPLM, European Commission, International Atomic Energy Agency, Vienna (Austria), the Abdus Salam International Centre for Theoretical Physics, Trieste (Italy) and the US Department of Energy. We would like to thank cordially our sponsors. Their financial support made it possible for a number of students and teachers to come to Kudowa Zdrój. We are very grateful to Dr Adam Ziembinski, the director of the spa in Kudowa, and his staff for the immense hospitality during our stay. We wish to thank Mr Czeslaw Krecichwost, the mayor of Kudowa Zdrój, for his strong support and interest in the School and help in organizing the lectures for scholars and residents of the region. And our most cordial thanks and gratitude go to Mr Ryszard Panfil for his great kindness, inexhaustible energy and organizational efficiency that helped all of us to enjoy the meeting.

Full Text Available Linguistic Tools in an Extreme Situation. Stanisław Lem’s Fantastic Worlds Built with Words The present issue of "Colloquia Humanistica" contains Professor Ryszard Handke's two last essays, until now unpublished. They belong together and deal with the works of Stanisław Lem, namely with the creation of a sui generis dictionary of this outstanding sci-fi writer. Handke highlights the coming of a new age in the evolution of the genre, already foreshadowed in Lem's early novels. This new sci-fi abandons uncritical beliefs in the power of science leading man to the conquest of cosmos and to a perfection of Earth's civilization. In Handke's analysis, in his first essay discussing "Astronauts" and "Magellan's Nebula," and in the second devoted to "Eden," Lem's evolution starts from a blind faith in the Marxist progress of civilization based on materialistic technocracy and moves towards an increasingly open polemic with this point of view, clearly demonstrating the beginning of doubts or of caution against an excessive faith in progress. The author of the essays is principally interested in the linguistic layer of the novels, the sci-fi terminology designating phenomena, objects or equipments from the imagined future. Handke analyzes the world reflected in the language and attempts to assemble a corpus invented by Lem in order to create an illusion of the future. The language seen from the perspective of the two texts remains a meaningful platform, but not a transparent one. This is where the space of the author's game with the readers begins, the space of inter-textual, cultural references, where the mentioned earlier naiveté of the older science fiction breaks down and an element of doubt, surprise, or irony surfaces frequently. The use of concrete linguistic means is conditioned by the creation of a world displaying a clearly determined character that borrows its particularities from the linguistic image of a fictional quasi-reality.

The Corinnidae of the western Pacific are revised. The formerly sparassid genus Anchognatha Thorell, 1881, and the gnaphosid genus Battalus Karsch, 1878, are transferred to the Castianeirinae. The Corinninae include only the introduced Creugas gulosus Thorell, 1878 and Medmassa christae sp. nov. from the northern Torres Strait islands. Medmassa pallipes (L. Koch, 1873) and Medmassa pusilla Simon, 1896 are newly synonymised with Creugas gulosus. The Castianeirinae from the Western Pacific including Australia includes Battalus Karsch, 1878, Copa Simon, 1886, Leichhardteus Raven & Baehr, 2013, Nyssus Walckenaer, 1805, Poecilipta Simon, 1897, and eight new genera: Disnyssus gen. nov., Iridonyssus gen. nov., Kolora gen. nov., Leptopicia gen. nov., Melanesotypus gen. nov., Nucastia gen. nov., Ozcopa gen. nov. and Ticopa gen. nov. Battalus includes B. adamparsonsi sp. nov., B. baehrae sp. nov., B. bidgemia sp. nov., B. byrneae sp. nov., B. diadens sp. nov., B. helenstarkae sp. nov., B. microspinosus sp. nov., B. rugosus sp. nov., B. spinipes Karsch, 1878, B. wallum sp. nov., B. zuytdorp sp. nov. and B. semiflavus (Simon, 1896), new combination (transferred from Medmassa). Copa, an otherwise African and Sri Lankan genus, includes C. kabana sp. nov. Disnyssus gen. nov. includes D. helenmirrenae sp. nov. and D. judidenchae sp. nov. Iridonyssus gen. nov. includes I. auripilosus sp. nov., I. formicans sp. nov., I. kohouti sp. nov. and I. leucostaurus sp. nov. Kolora gen. nov. includes K. cushingae sp. nov., K. cooloola sp. nov. and K. lynneae sp. nov., and K. sauverubens (Simon, 1896) new combination (transferred from Corinnomma Karsch, 1880). Leichhardteus includes Leichhardteus yagan sp. nov., Leichhardteus evschlingeri sp. nov., Leichhardteus strzelecki sp. nov., as well as eight recently described species. Leptopicia gen. nov. includes only Methesis bimaculata (Simon, 1896) new combination (transferred from Methesis Simon, 1896). Melanesotypus guadal gen. et sp. nov. is

Stellar students win fantastic prizes

will meet astronomers and be present during a night of observations. Learning that they won, the team was enthusiastic: "We are very pleased to hear this fantastic news and are looking forward to the trip!" Another winner was Marta Kotarba, with her teacher Grzegorz Sęk, from the school IV Liceum Ogólnokształcące im. Tadeusza Kościuszki, Poland. Her prize is a trip to the Hispano-German Astronomical Observatory of Calar Alto in Almeria, Spain, kindly donated by the Spanish Council for Scientific Research. Marta's project "Galaxy Zoo and I" tells how she joined the website "Galaxy Zoo" to study galaxies and help astronomical researchers understand the structure of the Universe. Galaxy Zoo volunteers classify galaxies into different types, such as spiral or elliptical - a task much more easily done by humans than computers. Marta explains that the project "is like an adventure to me. Galaxy Zoo gives me abilities to enlarge my knowledge about the Universe and to gain new skills." Her winning entry also shows how anyone can get involved in the world of real astronomical research, simply by using the Internet. A third winner, of a trip to Königsleiten Observatory in Austria, is Andreia Nascimento with her teacher Leonor Cabral, from Escola Secundária da Cidadela in Portugal. Her project, on "Hunting for Open Star Clusters" near young stars, used data from the robotic Faulkes Telescope in Hawaii, which is used for research-based science education. "Catch a Star" also includes an artwork competition, for which students created artwork with an astronomical theme. This competition, through which students can get involved with astronomy even outside of science classes, has become increasingly popular, with over one thousand entries this year from around the world. Not only were prizes awarded by public votes in a web gallery, but special prizes were awarded by Garry Harwood, a Fellow and life member of the International Association of Astronomy Artists. Harwood said: "It

Cel pracy: Istotnym problemem badawczym jest wpływ poszczególnych zabiegów fizykalnych na konkretną grupę mięśniową. Dzięki badaniom za pomocą EMG możemy skutecznie ocenić skutki terapii po zastosowaniu prądów TENS średniej częstotliwości. Celem pracy była analiza  z wykorzystaniem EMG, wpływu prądów TENS średniej częstotliwości na czynność bioelektryczną mięśni prostowników nadgarstka. Wyniki badań własnych: Szczegółowe wyniki przeprowadzonych badań przedstawiono w tabelach i zilustrowano wykresami. Materiał i metoda: W badaniach uczestniczyło 19 osób, które nie zgłosiły większych dolegliwości ze strony badanej grupy mięśniowej. W grupie badawczej uczestniczy zarówno kobiety jak i mężczyźni. Głównym narzędziem badawczym, które pozwoliło na analizę badań był pomiar za pomocą EMG,  gdzie została oceniona czynność bioelektryczna (rónica potencjałów mięśni w spoczynku, podczas skurczu koncentrycznego w ruchu zgięcia grzbietowego nadgarstka oraz wykonanie próby maksymalnego skurczu dowolnego MVC. Analiza zapisu EMG mięśnia prostownika promieniowego nadgarstka oraz prostownika łokciowego nadgarstka wykazała spadek częstotliwości wyładowań bioelektrycznych mięśnia pod wpływem działania prądów TENS średniej częstotliwości.
