description: I present a brief review of the existing models for particle multiplicity evaluation in heavy ion collisions which are at our disposal in the form of Monte Carlo simulators. Models are classified according to the physical mechanisms with which they try to describe the different stages of a high-energy collision between heavy nuclei. A comparison of predictions, as available at the beginning of year 2000, for multiplicities in central AuAu collisions at the BNL Relativistic Heavy Ion Collider (RHIC) and PbPb collisions at the CERN Large Hadron Collider (LHC) is provided.

description: The article describes the changes that have taken place in the domestic and global rapeseed market in the first years after the Polish accession to the EU (2004-2007) and subsequent years (2008-2012), compared with the period before accession (2000-2003). The assessment of these changes were carried out on the basis of average annual data for selected period. It has been shown that the Polish accession to the EU and EU policy on biofuels and renewable energy and increased the rate of development of production, processing and trade of rape and products of its processing. Poland has become a part of the global market and, therefore, fluctuations of domestic rapeseed prices are significantly affected by changes in oilseed prices on the European and American commodity markets. / Synopsis. Celem artykułu było przedstawienie zmian jakie nastąpiły na krajowym i światowym rynku rzepaku w pierwszych latach po akcesji Polski do UE (lata 2004-2007) i w kolejnych (lata 2008-2012), w porównaniu z okresem przed akcesją (lata 2000-2003). Ocenę tych zmian przeprowadzono na podstawie danych średniorocznych dla wybranych okresów. Wykazano, że wejście Polski do UE i polityka Unii w zakresie produkcji biopaliw i energii odnawialnej zdynamizowały rozwoju produkcji, przetwórstwa i handlu rzepakiem i produktami jego przerobu. Polska stała się częścią rynku globalnego i dlatego na wzrosty i spadki cen rzepaku na rynku krajowym znaczący wpływ mają zmiany cen surowców oleistych, które następują na europejskich, a także amerykańskich giełdach.

description: We present an analysis of seasonal cycle of the last 50 years of records of surface temperature in Italy. We consider two data sets which synthesize the surface temperature fields of Northern and Southern Italy. Such data sets consist of records of daily maximum and minimum temperature. We compute the best estimate of the seasonal cycle of the variables considered by adopting the cyclograms' technique. We observe that in general the minimum temperature cycle lags behind the maximum temperature cycle, and that the cycles of the Southern Italy temperatures records lag behind the corresponding cycles referring to Northern Italy. All seasonal cycles lag considerably behind the solar cycle. The amplitude and phase of the seasonal cycles do not show any statistically significant trend in the time interval considered.

description: The recently released IEEE 802.15.6 standard specifies several physical (PHY) layer and medium access control (MAC) layer protocols for variety of medical and non-medical applications of Wireless Body Area Networks (WBAN). The most suitable way for enhancing network performance is to be the choice of different MAC and PHY parameters based on quality of service (QoS) requirements of different applications. The impact of different MAC and PHY parameters on the network performance and the trade-off relationship between the parameters are essential to overcome the limitations of exiting carrier sense multiple access with collision avoidance (CSMA/CA) scheme of IEEE 802.15.6 standard. To address this issue, we develop a Markov chain-based analytical model of IEEE 802.15.6 CSMA/CA for all user priorities (UPs) and apply this general model to different network scenarios to investigate the effects of the packet arrival rate, channel condition, payload size, access phase length, access mechanism and number of nodes on the performance parameters viz. reliability, normalized throughput, energy consumption and average access delay. Moreover, we conclude the effectiveness of different access phases, access mechanisms and user priorities of intra-WBAN.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

These master integrals are relevant for the QCD corrections to H to V*V* (where V = W, Z) and for two-loop studies of the triple gluon (and quark-gluon) vertex. We employ the differential equation technique to provide series expansions in epsilon for the various master integrals. The results are analytic and contain a new class of two-dimensional harmonic polylogarithms.

Earthquake-induced hazards in mountain regions: a review of case histories from Central Asia -- an inaugural lecture to the society

Subjects: subject: Geophysics (physics.geo-ph)

description: This paper presents a summary of the main trigger factors of earthquake-induced landslides as well as a review of case histories of major landslide-triggering earthquake events in Central Asia. The Kainama earth-flow case history of 2005 is added to document possible mid-term effects of smaller earthquakes. These events show that in the Central Asian Mountains, two types of seismically triggered mass movements may have particularly disastrous effects: massive long runout rockslides and medium-sized earth flows made of loess -- or a mixture of both. These types of mass movements also significantly contributed to the largest natural catastrophe of the last century in Central Asian mountain regions: the 1949 Khait earthquake.The high impact potential of these types of mass movements is further pointed out through comparison with two worldwide known events, the 1920 Haiyuan (China) and the 1976 Peru earthquake.Case studies had been carried out on rockslides, debris slumps and earth flows triggered by the above-mentioned Kemin and Suusamyr earthquakes as well as other smaller seismic shocks in the Kyrgyz Tien Shan. Many of the investigated landslides had known a complex failure history before final collapse. To better assess the short- to long-term effects of earthquakes on slopes, landslides need to be surveyed more intensively, over mid- and long-terms.
Magnetohydrostatic modeling of AR11768 based on a SUNRISE/IMaX vector magnetogram

description: Context. High resolution magnetic field measurements are routinely done only in the solar photosphere. Higher layers like the chromosphere and corona can be modeled by extrapolating the photospheric magnetic field upward. In the solar corona, plasma forces can be neglected and the Lorentz force vanishes. This is not the case in the upper photosphere and chromosphere where magnetic and non-magnetic forces are equally important. One way to deal with this problem is to compute the plasma and magnetic field self-consistently with a magnetohydrostatic (MHS) model. Aims. We aim to derive the magnetic field, plasma pressure and density of AR11768 by applying the newly developed extrapolation technique to the SUNRISE/IMaX data. Methods. An optimization method is used for the MHS modeling. The initial conditions consist of a nonlinear force-free field (NLFFF) and a gravity-stratified atmosphere. Results. In the non-force-free layer, which is spatially resolved by the new code, Lorentz forces are effectively balanced by the gas pressure gradient force and the gravity force. The pressure and density are depleted in strong field regions, which is consistent with observations. Denser plasma, however, is also observed at some parts of the active region edges. In the chromosphere, the fibril-like plasma structures trace the magnetic field nicely. Bright points in SUNRISE/SuFI 3000 {$Å$} images are often accompanied by the plasma pressure and electric current concentrations. In addition, the average of angle between MHS field lines and the selected chromospheric fibrils is $11.8^\circ$, which is smaller than those computed from the NLFFF model ($15.7^\circ$) and linear MHS model ($20.9^\circ$). This indicates that the MHS solution provides a better representation of the magnetic field in the chromosphere.

description: Jet quenching studies play a prominent role in our current understanding of ultra-relativistic heavy ion collisions. In this review I first present the available formalism to compute medium-induced gluon radiation. Then I discuss its effect on single particle spectra, with dedicated attention to the case of the radiating parton being a massive quark. Next I examine more differential observables like jet shapes and multiplicities, and the consequences of flow on radiative energy loss. I conclude with some remarks.

description: Young stars accrete mass and angular momentum from their circumstellar disks. Some of them also drive outflows, which can be distinguished in optical forbidden emission lines (FELs). We analyze a sample of binary T Tauri stars observed with long-slit spectroscopy by the Hubble Space Telescope (HST), searching for spatially resolved outflows. We detect resolved [O I] emission in two cases out of twenty one. In DF Tau we resolve high and medium velocity outflows in a jet and counterjet out to 60 au. The outflows are accelerated within the inner 12 au and retain a constant speed thereafter. In UY Aur, we detect a blue- and a red-shifted outflow from UY Aur A, as well as a blue-shifted jet from UY Aur B. All of these features have been seen in [Fe II] with data taken ten years apart indicating that the underlying outflow pattern is stable on these timescales.

description: Milk production and procurement in Poland and UE-15 show a clear seasonal fluctuations which are determined by the distribution of calving and feeding regimes. The seasonal fluctuations are transferred on the consequent stages of the food chain and also have got numerous microeconomic implications. A decomposition of time series makes possible differentiation of seasonal fluctuations analysis and measurement of patterns. In Poland over the period of 2001-2013 the largest seasonal variability featured exports of dairy products and milk supply (deliveries) to the dairy industry. On the other hand procurement prices were much less volatile because to a large extent they were dependent upon changes in the situation on international market as well as upon stochastic factors. Over the concerned period the seasonal fluctuations on the dairy market have diminished. / Synopsis. Produkcja i skup mleka w Polsce i UE-15 wykazują wyraźne wahania sezonowe, które są determinowane rozkładem wycieleń i systemem żywienia. Wahania sezonowe podaży surowca przenoszą się na kolejne etapy łańcucha marketingowego oraz mają wiele skutków mikroekonomicznych. Dekompozycja szeregów czasowych umożliwia wyodrębnienie wahań sezonowych, analizę i pomiar prawidłowości. W Polsce w latach 2001-2013 największą zmiennością sezonową charakteryzował się eksport produktów mleczarskich oraz dostawy mleka do przemysłu, a najmniejszą ceny skupu, które w znacznym stopniu zleżały od wahań koniunkturalnych na międzynarodowym rynku i losowych. Wahania sezonowe na rynku mleka ewoluowały w czasie i analizowanym okresie uległy znacznemu zmniejszeniu.

description: Over the period of 2011-2012 the scope of economic activities in many Member States decreased. As a result of that the demand for food declined. The situation on labour market deteriorated - unemployment increased and employment went down. The rate of household income growth diminished. An upward trend in food prices in real terms was continued in 2012 corresponding to the previous year. Such developments were driven by negative consumer attitudes, which was reflected in their purchases decisions. In 2011 annual expenditure on food (in real terms) in the EU-27 averaged 0,6% down on the previous year. In 2012 the expenditure declined further which seems to be confirmed with the figures on retail sales. In 2012 as compared with 2011 the retail sales of food, beverages and tobacco at constant prices were 0,9% down and 1,3% down in the euro zone. In 2011, in the countries where household incomes have risen the most – demand for food is also the largest increased. / Synopsis. W 2012 r. dynamika PKB była ujemna i wyniosła w UE-27 -0,3%. Pogorszyła się sytuacja na rynku pracy. Zharmonizowana średnioroczna stopa bezrobocia w UE w 2012 r. ukształtowała się na poziomie 10,6%. Spowolnieniu uległa dynamika dochodów ludności. W 2012 r. utrzymała się, obserwowana w roku poprzednim, tendencja realnego drożenia żywności. Zjawiska te były związane ze słabymi nastrojami konsumentów, co znalazło odzwierciedlenie w decyzjach zakupowych. W 2011 r., w UE-27 przeciętne roczne wydatki realne na żywność w sektorze gospodarstw domowych były o 0,6% mniejsze niż w roku poprzednim, w którym wzrosły o 2,0%. W 2012 r. w porównaniu z 2011 r. w UE-27 uległy one dalszej redukcji. Potwierdzają to dane o sprzedaży detalicznej. W 2012 r., w porównaniu z 2011 r. w UE-27 spadek sprzedaży detalicznej żywności, napojów i tytoniu, w cenach stałych, wyniósł 0,9% , a w strefie euro 1,3% i był większy, niż sprzedaży ogółem. W 2011 r., w krajach w których dochody ludności wzrosły najbardziej, nastąpił największy wzrost popytu na żywność.

description: Membrane systems are a biologically-inspired computational model based on the structure of biological cells and the way chemicals interact and traverse their membranes. Although their dynamics are described by rules, encoding membrane systems into rewriting logic is not straightforward due to its complex control mechanisms. Multiple alternatives have been proposed in the literature and implemented in the Maude specification language. The recent release of the Maude strategy language and its associated strategy-aware model checker allow specifying these systems more easily, so that they become executable and verifiable for free. An easily-extensible interactive environment transforms membrane specifications into rewrite theories controlled by appropriate strategies, and allows simulating and verifying membrane computations by means of them.

description: Motivated by some well-known results in the phase space description of quantum optics and quantum information theory, we aim to describe the formalism of quantum field theory by explicitly considering the holomorphic representation for a scalar field within the deformation quantization program. Notably, the symbol of a symmetric ordered operator in terms of holomorphic variables may be straightforwardly obtained by the quantum field analogue of the Husimi distribution associated with a normal ordered operator. This relation also allows establishing a $c$-equivalence between the Moyal and the normal star-products. In addition, by writing the density operator in terms of coherent states we are able to directly introduce a series representation of the Wigner functional distribution which may be convenient in order to calculate probability distributions of quantum field observables without performing formal phase space integrals at all.

Interconnect driver design for long wires in field-programmable gate arrays
Creators: name: Lee, Edmund
Publisher: name: University of British Columbia
Year: 2010

description: Designers of field-programmable gate arrays (FPGAs) are always striving to improve the performance of their designs. As they migrate to newer process technologies in search of higher speeds, the challenge of interconnect delay grows larger. For an FPGA, this challenge is crucial since most FPGA implementations use many long wires. A common technique used to reduce interconnect delay is repeater insertion. Recent work has shown that FPGA interconnect delay can be improved by using unidirectional wires with a single driver at only one end of a wire. With this change, it is now possible to consider interconnect optimization techniques such as repeater insertion. In this work, a technique to construct switch driver circuit designs is developed. Using this method, it is possible to determine the driver sizing, spacing and the number of stages of the circuit design. A computer-aided design model of the new circuit designs is developed to assess the impact they have on the delay performance of FPGAs. Results indicate that, by using the presented circuit design technique, the critical path can be reduced by 19% for short wires, and up to 40% for longer wires.

description: Bound states of the neutron-deficient, near-dripline nucleus $^{36}$Ca were populated in two-neutron removal from the ground state of $^{38}$Ca, a direct reaction sensitive to the single-particle configurations and couplings of the removed neutrons in the projectile wave function. Final-state exclusive cross sections for the formation of $^{36}$Ca and the corresponding longitudinal momentum distributions, both determined through the combination of particle and $γ$-ray spectroscopy, are compared to predictions combining eikonal reaction theory and shell-model two-nucleon amplitudes from the USDB, USDC, and ZBM2 effective interactions. The final-state cross-section ratio $σ(2^+_1)/σ(0^+)$ shows particular sensitivity and is approximately reproduced only with the two-nucleon amplitudes from the ZBM2 effective interaction that includes proton cross-shell excitations into the $pf$ shell. Characterizing the proton $pf$-shell occupancy locally and schematically, an increase of the $sd$-$pf$ shell gap by $250$ keV yields an improved description of this cross-section ratio and simultaneously enables a reproduction of the $B(E2;0^+_1\to2^+_1)$ excitation strength of $^{36}$Ca. This highlights an important aspect if a new shell-model effective interaction for the region was to be developed on the quest to model the neutron-deficient Ca isotopes and surrounding nuclei whose structure is impacted by proton cross-shell excitations.

description: Raspberries become an important part of Polish export offer. International trade of fresh raspberries is however, limited due to their vulnerability to damages. Consequently the international trade involves mostly countries in the neighborhood. The main part of raspberries sales falls on frozen fruits. Frozen raspberries production in Poland is developed very well. That is why our country increases its share in the global market. An article has aimed to analyze the changes in harvest and global trade of raspberries. Main global exporters and producers of fresh raspberries will be identified, as well as the receivers of frozen raspberries. Furthermore the polish position on the global market will be described, with pointing out the main competitors of our country. / Synopsis. Maliny stają się istotną ofertą eksportową Polski. Międzynarodowy handel świeżymi owocami jest jednak ograniczany przez ich trwałość i przeważnie odbywa się pomiędzy krajami blisko siebie położonymi. Większa część obrotów malinami przypada na ich mrożonki. Ta grupa produktów jest silną stroną naszego kraju. Dzięki temu Polska systematycznie zdobywa coraz większy udział w rynku. Artykuł ma na celu przeanalizowanie zmian zachodzących w zbiorach i obrotach malinami na świecie. Zidentyfikowani zostaną główni eksporterzy oraz odbiorcy tych owoców jak i wytwarzanych z nich mrożonek. Ponadto określona zostanie pozycja Polski na rynku światowym i unijnym ze wskazaniem najważniejszych konkurentów naszego kraju.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Inclusive cross-sections for gluon jet production are studied numerically in the perturbative QCD pomeron model for pA and central AA collisions at high energies. Two forms for the inclusive cross-sections, with and without emission from the triple pomeron vertex, are compared. The difference was found to reduce to a numerical factor 0.7-0.8 for momenta below the saturation momentum Q_s. Above Q_s no difference was found at all. For pA collisions the jet spectrum was found to be \sim A^{0.7} at momenta below Q_s and \sim A^{0.9} above it. For central AA collisions it was found to be \sim A below Q_s and \sim A^{1.1} above it. At large momenta k the spectrum goes like 1/k^{2.7 - 3.3} flattenung with energy.

description: In the reflective Maude specification language, based on rewriting logic, a strategy language has been introduced to control rule rewriting while avoiding complex and verbose metalevel programs. However, just as multiple levels of reflection are required for some metaprogramming tasks, reflective manipulation and generation of strategies are convenient in multiple situations. Some examples of reflective strategy transformations are presented, which implement special forms of evaluation or extend the strategy language while preserving its advantages.

description: A Finsler space is said to be geodesically reversible if each oriented geodesic can be reparametrized as a geodesic with the reverse orientation. A reversible Finsler space is geodesically reversible, but the converse need not be true. In this note, building on recent work of LeBrun and Mason, it is shown that a geodesically reversible Finsler metric of constant flag curvature on the 2-sphere is necessarily projectively flat. As a corollary, using a previous result of the author, it is shown that a reversible Finsler metric of constant flag curvature on the 2-sphere is necessarily a Riemannian metric of constant Gauss curvature, thus settling a long-standing problem in Finsler geometry.

"Moving towards Sustainable Cities" A study on the Municipal Budgeting process for Sustainable Urban Active Transport
Creators: name: Yogeshwari Rohit*

Publisher: name: Zenodo
Year: 2025
Subjects: Municipal Budgeting, Sustainable Transport Systems, Policy Framework, Active Mobility

description: Abstract: A municipal budget is a process of allocation of funds that acts as a benchmark to control fiscal operations which can serve as a guiding tool for the operations of the municipalities and municipal corporations. Furthermore, the budgeting process can assess the appropriateness of funding the various development projects and implementation of national or state-level schemes and policies at a level. Currently, in many of the developed countries across the globe, the promotion of local government for the management of urban development has been taking place. This shift in the paradigm of local governance is being emphasized to empower the urban local bodies and distribute power between the central and the state in the context of a broader interest in decentralization. This paper tries to understand the various processes through which different municipal corporations and municipalities formulate the annual session budgeting plans and their implementation in the transportation sector through the plethora of innovative projects. It tries to create an understanding of the municipal budgeting processes of various ULBs of different Indian cities and a comparative analysis made by assessing the funding and jurisdiction over the decision-making processes in an effort to provide greater devolution to the state and local representative bodies. The understanding gained would then be utilized to formulate a basic generalized framework of municipal budgeting in the urban transport field of the selected cities for the study to fulfil a variety of Sustainable Goals, specifically Sustainable Goal 11.
Entanglement transitions as a probe of quasiparticles and quantum thermalization

description: We introduce a diagnostic for quantum thermalization based on mixed-state entanglement. Specifically, given a pure state on a tripartite system $ABC$, we study the scaling of entanglement negativity between $A$ and $B$. For representative states of self-thermalizing systems, either eigenstates or states obtained by a long-time evolution of product states, negativity shows a sharp transition from an area-law scaling to a volume-law scaling when the subsystem volume fraction is tuned across a finite critical value. In contrast, for a system with quasiparticles, it exhibits a volume-law scaling irrespective of the subsystem fraction. For many-body localized systems, the same quantity shows an area-law scaling for eigenstates, and volume-law scaling for long-time evolved product states, irrespective of the subsystem fraction. We provide a combination of numerical observations and analytical arguments in support of our conjecture. Along the way, we prove and utilize a `continuity bound' for negativity: we bound the difference in negativity for two density matrices in terms of the Hilbert-Schmidt norm of their difference.
