description: Többéves kutatómunkánk eredményei alapján – jelen tanulmányban – az elméleti összefüggések tisztázásával definiáljuk a forgótőke, az idényszerűen jelentkező forgóeszközök, a forgóbefektetés, a nettó forgótőke, működő tőke és ezekkel összefüggésben a forgótőke-menedzsment fogalmakat. A forgótőke-menedzsment nem egyéb, mint a termelési folyamat gazdaságtana. Mint diszciplína, a termelési folyamat gazdasági vetületét veszi alapul, a körforgás elemeivel és a forgótőkével való gazdálkodás – készletgazdálkodás, a vállalat kereskedelmi, hitelezési politikája, a pénzeszközökkel való gazdálkodás –, valamint a kapcsolódó finanszírozási döntések állnak vizsgálódásának középpontjában. --------------------------------------------------- Those literary sources dealing with such topics as the interpretation of working capital in the context of corporate financing strategies, the related financial indices, and the methodology of calculating all these, could be considered neither poor, nor unified. Several problems arise from the shortcomings of defining the concepts of working capital, net working capital, working (operational) capital, the circulation of current assets and working capital management, etc., which gives the theoretical basis and their vocational tenability, the controversial interpretation and the unclearness of the related methodological questions. On the other hand, the root of the problems can be found in the unclearness of the theoretical contexts, in the deficiency and vocational tenability of the defining of the related concepts, categories. We define the concepts of working capital, net working capital, working (operating) capital based on the results of our several years’ research work. We prove the theoretical basis of the concepts and open up the causal connections and the interactions of the different elements. We prove that the correction of the related financial indices can not be considered apart from the interpretation of the theoretical contexts.

description: Nyolc mezőgazdasági vállalkozás utóbbi hat évben közzétett éves beszámolója, valamint a jogi szabályozás vizsgálata alapján megállapítható, hogy elméleti és gyakorlati szempontból is van különbség a számviteli és a pénzügyi eredménykategóriák között. A számítások elvégzéséhez szükséges információkat, adatokat az éves és az egyszerűsített éves beszámoló is tartalmazza. Az adatok összegyűjtéséhez, csoportosításához az agrárközgazdászoknak nincsen szüksége számviteli alapismeretekre, elég, ha tudják az éves beszámolókat olvasni, ami minden gazdasági területen dolgozó vezetőtől, kutatótól jogosan elvárható. --------------------------------------- Our study of the financial statements of eight agricultural enterprises for the past six years and the applicable legal regulations has shown that there is a difference between accounting profit and financial profit both in terms of theory and practice. The information required for the calculations are disclosed in both the annual financial statements and the simplified annual financial statements. Agro-economists do not need any basic accounting skills to collect and sort the data. It is enough to be able to understand such annual financial statements, which can be reasonably expected from any manager or researcher working in any economic field.

description: A tanulmányban bemutatott takarmányárak és a pulykahús-előállítás jövedelme közötti rendkívül szoros kapcsolat elgondolkodtató, mert a takarmány – mint a legfontosabb inputtényező – árának változása vállalatcsoportok átrendeződését eredményezheti. A takarmányárak fokozatos és lassú ütemű emelkedése ugyan különböző költséggazdálkodási eszközökkel egy bizonyos pontig ellensúlyozható, de a jelen tanulmányban vizsgált időtartam alatt két ízben is tapasztalt rendkívül drasztikus mértékű takarmányár-emelkedés által okozott hatások kivédésére az ágazat szereplőinek nincsen eszköze. Amennyiben a jövőben is előfordulnak hasonló mértékű takarmányáremelkedések, akkor azok vállalati csődökkel kísért szerkezeti átrendeződést is okozhatnak az ágazatban. ---------------------------------------------- The very strong relationship between feedstuff prices and the profits from turkey meat production, demonstrated in the paper, should make one think, because changes in the price of feedstuffs – the primary input for the industry – may cause reorganisation of groups of companies. Although the gradual, slow increase of feedstuff prices can be set off by various cost management practices up to a certain limit, the industry players do not have any way to fend off the extremely drastic increases in feedstuff prices which were seen on two occasions in the period covered by the study. Should feedstuff prices increase at similar rates in the future, they may cause bankruptcies and a structural reorganisation in the industry.

description: We present X-ray and optical observations of a new transient X-ray source in M31 first detected 23-May-2004 at R.A.=00:43:09.940 +/- 0.65'', Dec.=41:23:32.49 +/- 0.66''. The X-ray lightcurve shows two peaks separated by several months, reminiscent of many Galactic X-ray novae. The location and X-ray spectrum of the source suggest it is a low mass X-ray binary (LMXB). Follow-up HST ACS observations of the location both during and after the outburst provide a high-confidence detection of variability for one star within the X-ray position error ellipse. This star has $Δ$B ~ 1 mag, and there is only a ~1% chance of finding such a variable in the error ellipse. We consider this star a good candidate for the optical counterpart of the X-ray source. The luminosity of this candidate provides a prediction for the orbital period of the system of 2.3$^{+3.7}_{-1.2}$ days.

description: Building Management Systems (BMS) are crucial in the drive towards smart sustainable cities. This is due to the fact that they have been effective in significantly reducing the energy consumption of buildings. A typical BMS is composed of smart devices that communicate with one another in order to achieve their purpose. However, the heterogeneity of these devices and their associated meta-data impede the deployment of solutions that depend on the interactions among these devices. Nonetheless, automatically inferring the semantics of these devices using data-driven methods provides an ideal solution to the problems brought about by this heterogeneity. In this paper, we undertake a multi-dimensional study to address the problem of inferring the semantics of IoT devices using machine learning models. Using two datasets with over 67 million data points collected from IoT devices, we developed discriminative models that produced competitive results. Particularly, our study highlights the potential of Image Encoded Time Series (IETS) as a robust alternative to statistical feature-based inference methods. Leveraging just a fraction of the data required by feature-based methods, our evaluations show that this encoding competes with and even outperforms traditional methods in many cases.

description: We propose a mechanism for high critical temperature (T_c) in the coexistent phase of superconducting- (SC) and antiferromagnetic (AF) CuO_2 planes in multilayered cuprates. The Josephson coupling between the SC planes separated by an AF insulator (Mott insulator) is calculated perturbatively up to the fourth order in terms of the hopping integral between adjacent CuO_2 planes. It is shown that the AF exchange splitting in the AF plane suppresses the so-called pi-Josephson coupling, and the long-ranged 0-Josephson coupling leads to coexistence with a rather high value of T_c.

description: Kérdőíves felmérésünkből megállapítható, hogy a válaszadók főfoglalkozásként végzik tevékenységüket, de mindenképpen tartanak mellette más – többnyire hagyományos – haszonállatot is. Többen jól felismerték a lehetőséget – a fajta jellegéből, látványosságából adódóan – falusi turizmus létrehozására. A háztáji termékfeldolgozással, annak törvényi szabályozása miatt nem foglalkoznak, pedig az ízvilág megismertetése a fogyasztókkal remekül beilleszthető a vendégfogadásba. Jelenleg értékesítési nehézségekkel küzdenek a termelők. Ha történik is eladás, akkor is kizárólag belföldre, pedig ezzekkel a termékekkel a külföldi piacokat is meg lehetne célozni, kihasználva ezzel hazánk komparatív előnyeit. -------------------------------------------------------- Our questionnaire-based survey found that respondents were pursuing their activities as a primary activity, but they all kept other livestock as well (usually also native species). Several respondents had realized the potential for rural tourism, arising from the spectacular appearance of the variety. They were not engaged in home food processing due to the relevant legislation, even though introducing the related flavours could comprise an ideal component of tourism. Producers are currently having issues selling their products. Even products which are sold are sold only on the domestic market, even though this product could be taken to foreign markets, making use of Hungary’s potential comparative advantages.

description: We show that turbulent dynamics that arise in simulations of the three-dimensional Navier--Stokes equations in a triply-periodic domain under sinusoidal forcing can be described as transient visits to the neighborhoods of unstable time-periodic solutions. Based on this description, we reduce the original system with more than $10^5$ degrees of freedom to a 17-node Markov chain where each node corresponds to the neighborhood of a periodic orbit. The model accurately reproduces long-term averages of the system's observables as weighted sums over the periodic orbits.

description: Synthetic approaches for modification of negative photochromes of hydroxytricyanopyrrole (HTCP) series were described for the first time. The first and fifth positions of the pyrrole ring were directly functionalized but hydroxyl group of the 2-vinyl-phenol fragment and the butadienetricarbonitrile (BDTC) moiety, which are necessary for the photochromic reaction were untouched. These results are the starting point for wide research in the field of directed synthesis of nitrile rich negative photochromes with tunable physicochemical characteristics.

description: Spin valve nanopillars are reversed via the mechanism of spin momentum transfer using current pulses applied perpendicular to the film plane of the device. The applied pulses were varied in amplitude from 1.8 mA to 7.8 mA, and varied in duration within the range of 100 ps to 200 ns. The probability of device reversal is measured as a function of the pulse duration for each pulse amplitude. The reciprocal pulse duration required for 95% reversal probability is linearly related to the pulse current amplitude for currents exceeding 1.9 mA. For this device, 1.9 mA marks the crossover between dynamic reversal at larger currents and reversal by thermal activation for smaller currents.

description: Az RFID egyedjelölési technológia kiépítését megelőző felmérések elvégzésekor meghatározásra került a jelölés egyedsűrűsége, valamint az RFID alapú egyedjelölési rendszer kiépítése során felmerülő költségtényezők. A tanulmány alapján megállapítható, hogy pecsenyekacsák esetében az állomány minimum 11-12%-át, hízott kacsáknál minimum 14-15%-át, pecsenyelibáknál minimum 12-13%-át, hízott libáknál minimum 14-15%-át kellene megjelölni a reprezentatív mintaelemszám elérése érdekében. A költségkalkuláció eredményei szerint a jelölés egyedsűrűségének függvényében a bevezetés évében 198-199 Ft többletköltséget jelentene egyedenként a rádiófrekvencián alapuló nyomon követési rendszer bevezetése, a példánkban említett vállalkozás számára. A rendszer bevezetését követően viszont már csak egy alacsonyabb pótlási költséggel (4000 Ft/termelési ciklus) kalkulálhat a vállalkozás. Bár többletbefektetést igényel egy ilyen rendszer kiépítése, de a 2011-ben életbe lépő Jogszabályban Foglalt Gazdálkodási Követelményeknek (JFGK – „C” csomag) való megfelelést elősegítené, ha sor kerülne a rádiófrekvencián alapuló azonosítás alkalmazására. ---------------------------------------------------- Prior to installing the RFID bird identification technology, the proportion of poultry to be tagged, as well as the costs of installing the RFID bird identification system were assessed. The paper concludes that to achieve a representative sample, the minimum percentage of animals to be tagged is 11-12% in the event of ducks for roasting, 14-15% for fattened ducks, 12-13% for geese for roasting, and 14-15% for fattened geese. It was calculated that – depending on the proportion of the animal to be tagged – introduction of RFID tracking would cost the company used in the example HUF 198-199 per animal in the initial year. In the subsequent years, however, only a lower replacement cost is incurred (HUF 4000 / production cycle). Although installing a similar system requires extra investment, the application of RFID identification would facilitate compliance with the Statutory Management Requirements (SMR – Package C) that become effective in 2011.
Crossing the divide : closing the cognitive and affective gaps that prevent successful reading in the upper elementary years
Creators: name: Lenters, Kimberly Ann
Publisher: name: University of British Columbia
Year: 2009

description: Significant numbers of children experience reading difficulty in the intermediate school years. Inexperience with expository text may partially explain this difficulty. While much of the extant research has focussed on the delivery of effective early interventions, investigation of efficacious practices with intermediate level struggling readers continues to require investigation. A case study that documents a research-based intervention with two struggling intermediate students is presented in this thesis. It explores a methodology that combines decoding and comprehension strategy instruction with fluency training, primarily utilizing expository text from children's popular literature. The strong positive results obtained are thought to be linked to the balancing of skill and strategy instruction with affective considerations. Phonological core deficits appear to have been addressed through oral repeated reading preceded by listening-previewing and accompanied by a "switched-on" self-monitoring for comprehension strategy. The findings suggest harmful effects may occur with some struggling readers from the use of fluency training that employs unengaging text and emphasizes speed over accuracy, expression and construction of meaning.
Is PSR J0726-2612 a dim isolated neutron star progenitor?

description: The rotational properties and X-ray luminosity of PSR J0726-2612 are close to those of dim isolated neutron stars (XDINs). It was proposed that the source could be the first XDIN with observable pulsed radio emission. We have investigated the long-term evolution of the source to test this possibility in the fallback disc model. Reasonable model curves that can account for the evolution of PSR J0726-2612 consistently with its radio pulsar property are similar to those of high-B radio pulsars with dipole field strength $B_0 \sim$ a few $\times 10^{12}~$G at the pole of the star. In the same model, XDINs are estimated to have relatively weak fields ($B_0 \lesssim 10^{12}~$G) locating them well below the pulsar death line. From the simulations, we estimate that PSR J0726-2612 is at an age of $t \sim 5 \times 10^4~$yr, and will achieve the rotational properties of a normal radio pulsar within $\sim 10^5~$yr, rather than the XDIN properties.

Megállapítható, hogy az előhasi üszőktől született borjak növendékállományon belül történő elszámolásának hatása vagyont és eredményt csökkentő tételként jelentkezik. Azt, hogy az elszámolásban keletkező különbözet milyen arányban jelenik meg vagyont és eredményt csökkentő tételként, azt a korosbítás gyakorlata is jelentősen befolyásolja. Ha az állományt már az első korcsoport után szétválasztják, akkor nagyobb hányad kompenzálja a tejre jutó költségnövekedést és kisebb lesz a vagyoncsökkenés. ------------------------------------------------------ This study focuses on how recording of calves in accordance with the accounting act affects net costs, profit/loss and the undertaking’s assets. It is found that recording calves born of cow in first calf as part of the young stock lowers assets and profit. The ratio to which the difference from such posting affects assets and profit is greatly influenced by age grouping practices. If stock are separated after the first age group, a larger portion sets off increased milk costs and there is a smaller reduction in assets.

description: We present a quantum extension of a version of Sanov's theorem focussing on a hypothesis testing aspect of the theorem: There exists a sequence of typical subspaces for a given set $Ψ$ of stationary quantum product states asymptotically separating them from another fixed stationary product state. Analogously to the classical case, the exponential separating rate is equal to the infimum of the quantum relative entropy with respect to the quantum reference state over the set $Ψ$. However, while in the classical case the separating subsets can be chosen universal, in the sense that they depend only on the chosen set of i.i.d. processes, in the quantum case the choice of the separating subspaces depends additionally on the reference state.

description: We consider the question of whether solutions of Klein--Gordon equations on asymptotically Anti-de Sitter spacetimes can be uniquely continued from the conformal boundary. Positive answers were first given by the second author with G. Holzegel, under suitable assumptions on the boundary geometry and with boundary data imposed over a sufficiently long timespan. The key step was to establish Carleman estimates for Klein--Gordon operators near the conformal boundary. In this article, we further improve upon the above-mentioned results. First, we establish new Carleman estimates---and hence new unique continuation results---for Klein--Gordon equations on a larger class of spacetimes, in particular with more general boundary geometries. Second, we argue for the optimality, in many respects, of our assumptions by connecting them to trajectories of null geodesics near the conformal boundary; these geodesics play a crucial role in the construction of counterexamples to unique continuation. Finally, we develop a new covariant formalism that will be useful---both presently and more generally beyond this article---for treating tensorial objects with asymptotic limits at the conformal boundary.

description: Near-infrared spectra of four QSOs located at $z>6$ are obtained with the OH-airglow suppressor mounted on the Subaru telescope. The FeII/MgII emission-line ratios of these QSOs are examined by the same fitting algorithm as in our previous study of $z<5.3$ QSOs. The fitting results show that two out of the four $z>6$ QSOs have significant FeII emission in their rest-UV spectra, while the other two have almost no FeII features. We also applied our fitting algorithm to more than 10,000 SDSS QSOs and found two trends in the distribution of FeII/MgII against redshift: (1) the upper envelope of the FeII/MgII distribution at $z>3$ shows a probable declination toward high redshift, and (2) the median distribution settles into lower ratios at $z\sim 1.5$ with small scatter compared to the other redshift. We discuss an Fe/Mg abundance evolution of QSOs with a substantial contribution from the diverse nature of the broad-line regions in high-redshift QSOs.

description: We consider the equilibrium thermal state of photons and determine the mean number and number variance of squeezed coherent photons. We use an integral representation for electro-magnetic radiation applicable both to systems in equilibrium and to systems in nonequilibrium to determine the spectral function of the radiation. The system considered is in thermal equilibrium and we find that the squeezed coherent photons are at a higher temperature than the photons themselves. Also, as expected, the mean number of squeezed coherent photons is greater than that of photons.

description: A mezőgazdasági vállalkozásokban jelentős kockázat az árkockázat. Fedezeti ügyletekkel aktív kockázatkezelést folytató gazdálkodók száma jelentősen elmarad a nemzetközi átlagtól. Az árutőzsde hatékony működése szükséges ahhoz, hogy megfelelő határidős ügyletekkel az árkockázat eliminálható legyen. A hatékonysági vizsgálatok igazolták a gyenge szintű tőkepiaci hatékonyság meglétét, így a hazai határidős piac ebből a szempontból alkalmas a hatékony kockázatmenedzsmentre. Ugyanakkor a hatékonyság rendre elmarad a fejlettebb azonnali részvénypiaci szekciótól. A piaci likviditás és párhuzamosan a piaci hatékonyság jelentősen növelhető lenne, amennyiben a mezőgazdasági vállalkozások megismernék, megértenék a határidős piacokban lévő kockázatmérséklési lehetőségeket. ----------------------------------------------------------- The second highest risk factor for agricultural enterprises is the price risk. Hedge transactions for agricultural risk management remarkably less used than in Western Europe or in the USA. Efficient operation of the commodity exchange is essential for eliminating price risk. The results confirm the weak form of the market efficiency, which means that – from this point of view – the market is applicable to the eligible risk management, albeit the level of efficiency is lower than the more developed equity exchange. The liquidity and the efficiency of the market could be improved by agricultural enterprises which are aware of and capable of using ways to mitigate risks.

description: Novel hysteretic effects are reported in magneto-transport experiments on lateral quantum devices. The effects are characterized by two vastly different relaxation times (minutes and days). It is shown that the observed phenomena are related to long-lived eddy currents. This is confirmed by torsion-balance magnetometry measurements of the same 2-dimensional electron gas (2DEG) material. These observations show that the induced quantum Hall potential at the edges of the 2DEG reservoirs influences transport through the devices, and have important consequences for the magneto-transport of all lateral quantum devices.

description: We present a comparative study of inflation in two theories of quadratic gravity with {\it gauged} scale symmetry: 1) the original Weyl quadratic gravity and 2) the theory defined by a similar action but in the Palatini approach obtained by replacing the Weyl connection by its Palatini counterpart. These theories have different vectorial non-metricity induced by the gauge field ($w_μ$) of this symmetry. Both theories have a novel spontaneous breaking of gauged scale symmetry, in the absence of matter, where the necessary scalar field is not added ad-hoc to this purpose but is of geometric origin and part of the quadratic action. The Einstein-Proca action (of $w_μ$), Planck scale and metricity emerge in the broken phase after $w_μ$ acquires mass (Stueckelberg mechanism), then decouples. In the presence of matter ($ϕ_1$), non-minimally coupled, the scalar potential is similar in both theories up to couplings and field rescaling. For small field values the potential is Higgs-like while for large fields inflation is possible. Due to their $R^2$ term, both theories have a small tensor-to-scalar ratio ($r\sim 10^{-3}$), larger in Palatini case. For a fixed spectral index $n_s$, reducing the non-minimal coupling ($ξ_1$) increases $r$ which in Weyl theory is bounded from above by that of Starobinsky inflation. For a small enough $ξ_1\leq 10^{-3}$, unlike the Palatini version, Weyl theory gives a dependence $r(n_s)$ similar to that in Starobinsky inflation, while also protecting $r$ against higher dimensional operators corrections.

Present Evidence for Intermediate Mass Black Holes in ULXs and Future Prospects
Creators: name: Miller, J. M.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In a number of the most luminous ULXs (L ~ 1 E+40 erg/s) in nearby galaxies, observations with XMM-Newton and Chandra are revealing evidence which suggests that these ULXs may harbor intermediate-mass black holes (IMBHs). The detection of accretion disk spectral components with temperatures 5-10 times lower than the temperatures observed in stellar-mass black hole binaries near to their Eddington limit may be particularly compelling evidence for IMBH primaries, since T ~ M^(-1/4) for disks around black holes. In some sources, X-ray timing diagnostics also hint at IMBHs. Evidence for IMBHs in a subset of the most luminous ULXs, a discussion of the robustness of this evidence and alternatives to the IMBH interpretation, and prospects for better determining the nature of these sources in the future, are presented in this work.

description: We examine, in a model independent way, the sensitivity of a Linear Collider to the couplings of a light Higgs boson to gauge bosons. Including the possibility of CP violation, we construct several observables that probe the different anomalous couplings possible. For an intermediate mass Higgs, a collider operating at a center of mass energy of 500 GeV and with an integrated luminosity of 500 fb$^{-1}$ is shown to be able to constrain the $ZZH$ vertex at the few per cent level, and with even higher sensitivity in certain directions. However, the lack of sufficient number of observables as well as contamination from the $ZZH$ vertex limits the precision with which the $WWH$ coupling can be measured.

Radio synchrotron spectra for a leaky box approximation
Creators: name: Kaiser, Christian R.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The synchrotron emission observed from many astrophysical objects is commonly modelled to arise from relativistic electrons in an emission region occupied by a spatially homogeneous, but tangled magnetic field. However, we know that magnetic fields embedded in ionised gases tend to form flux ropes interspersed with regions of much lower magnetic field strengths. Here we develop a full description of the evolution of the energy distribution of relativistic electrons in a plasma divided into two distinct regions with different strengths of the magnetic field. Electrons are able to continuously leak from the low-field region into the high-field region. The model becomes fully analytic for physically reasonable assumptions. We show that such a leaky box model produces two distinct breaks in the electron energy distributions which give rise to three breaks in the resulting synchrotron spectrum. The spectral slopes in between the breaks are in general not constant and thus allow for significant curvature of the spectrum. These spectra are consistent with spatially resolved observations of the radio spectra of the lobes of radio galaxies. The exact form of the spectra depends on the adopted diffusion rate. The leaky box model significantly extends the time over which synchrotron emission can be detected at a given frequency compared to the usually assumed case of homogeneous magnetic fields. The spectral ages inferred for the electron population from standard techniques for the leaky box model are considerably younger than their real age.

description: A vizsgált két szövetkezetnél és egy Zrt.-nél a földterületek nagyarányú csökkenését munkaerő-létszámcsökkenés kísérte. A pályát elhagyni kényszerültek jelentős, mintegy 30 százaléka tartósan munkanélkülivé vált, a többiek pedig más szektorokban (ipari, szolgáltatói) helyezkedtek el. A vezetők, illetve a dolgozók körében végzett kérdőíves és mélyinterjús felméréseink szerint a korösszetétel kedvezőtlen képet mutat: a dolgozói kollektíva napjainkra túlságosan elöregedett. A jövedelemviszonyokat figyelembe véve a gazdaságok egyre kevésbé vonzóak a fiatal agrárértelmiségiek számára. A fiatalabb munkavállalók szinte kivétel nélkül kevesellték a bérüket. Az iskolázottságot vizsgálva elmondható, hogy a férfiak körében alacsonyabb, a nőknél több a magasabb végzettséggel (érettségi, felsőfokú) rendelkezők aránya. A megkérdezett dolgozók elégedettek a munkakörülményeikkel, szeretnek az üzemekben dolgozni, és hosszú távon sem kívánnak munkahelyet váltani. --------------------------------------------------------------- Transformation of the two co-operatives studied and conversion of a co-operative into a company limited by shares was accompanied by a great reduction in land size as well as in staff size. A significant portion (approximately 30%) of the people who were forced to leave their jobs became permanently unemployed, while others found work in other sectors (industry, services). Our questionnaire and interview-based survey of the senior staff and employees outlined an unfavourable composition in terms of age: staff are in general rather aged. Due to income considerations, farms are less and less attractive for young agricultural white-collar workers. Nearly all young employees said they were paid too little. As for qualifications, it was found that the ratio of individuals with higher qualification (secondary school-leaving diploma, tertiary degree) was lower for en and higher for women. The employees we asked were satisfied with their work conditions, liked working in the plants and were not planning to find another job on the long term.

description: We develop a method to prove almost global stability of stochastic differential equations in the sense that almost every initial point (with respect to the Lebesgue measure) is asymptotically attracted to the origin with unit probability. The method can be viewed as a dual to Lyapunov's second method for stochastic differential equations and extends the deterministic result in [A. Rantzer, Syst. Contr. Lett., 42 (2001), pp. 161--168]. The result can also be used in certain cases to find stabilizing controllers for stochastic nonlinear systems using convex optimization. The main technical tool is the theory of stochastic flows of diffeomorphisms.

description: For any tangle $T$ (up to isotopy) and integer $k\geq 1$ we construct a group $F(T)$ (up to isomorphism). It is the fundamental group of the configuration space of $k$ points in a horizontal plane avoiding the tangle, provided the tangle is in what we call Heegaard position. This is analogous to the first half of Lawrence's homology construction of braid group representations. We briefly discuss the second half: homology groups of $F(T)$.

description: Napjainkban a világgazdaság egyik legfontosabb megoldásra váró problémája, hogy hogyan előzhető meg újabb globális pénzügyi és gazdasági válságok kialakulása, illetve léteznek-e olyan módszerek, eszközök, amelyek segítségével a már kialakult válságok hatásai, következményei mérsékelhetők. A módszerek, eszközök részben már rendelkezésre állnak, melyek közül célszerű kiemelni a konszern számvitel módszertanát, mert segítségével elkészíthető konszolidált éves beszámolót. E konszolidált éves beszámoló ugyanis alkalmas arra, hogy a konszerntagok közötti belső kapcsolatokból adódó halmozódásokat kiszűrve előmozdítsa a vállalatcsoportok reális megítélését. Segítségével elkerülhetővé válhat a – válság kialakulásában nagymértékben szerepet játszó – jogi, pénzügyi számviteli technikai elszámolásokon alapuló vagyon- és jövedelemhalmozódás kimutatása. ----------------------------------------------------- One of the most important pending issue in world economy today is finding a way to prevent future global economic and financial crises, as well as finding ways and tools to mitigate the effects and consequences of a crisis which has already occurred. Some methods and tools are already available – one which should be highlighted is holding accounting methodology and the consolidated annual reports prepared this way. Such consolidated annual reports facilitate realistic evaluation of the groups of undertakings by screening out accumulation resulting from internal transactions between members of the same group. They can help avoid results indicating accumulation of assets and revenues, derived from legal, financial and accounting technical reports, i.e. results which play an important role in the occurrence of crises.

description: The article analyzes the historical aspect of the formation of computer modeling as one of the perspective directions of educational process development. The notion of "system of computer modeling", conceptual model of system of computer modeling (SCMod), its components (mathematical, animation, graphic, strategic), functions, principles and purposes of use are grounded. The features of the organization of students work using SCMod, individual and group work, the formation of subject competencies are described; the aspect of students' motivation to learning is considered. It is established that educational institutions can use SCMod at different levels and stages of training and in different contexts, which consist of interrelated physical, social, cultural and technological aspects. It is determined that the use of SCMod in general secondary school would increase the capacity of teachers to improve the training of students in natural and mathematical subjects and contribute to the individualization of the learning process, in order to meet the pace, educational interests and capabilities of each particular student. It is substantiated that the use of SCMod in the study of natural-mathematical subjects contributes to the formation of subject competencies, develops the skills of analysis and decision-making, increases the level of digital communication, develops vigilance, raises the level of knowledge, increases the duration of attention of students. Further research requires the justification of the process of forming students' competencies in natural-mathematical subjects and designing cognitive tasks using SCMod.

description: We present a brief summary of exact results on the non-perturbative effective superpotential of N=1 supersymmetric gauge theories based on generalized Konishi anomaly equations. In particular we consider theories with classical gauge groups and chiral matter in two-index tensor representations. All these theories can be embedded into theories with unitary gauge group and adjoint matter. This embedding can be used to derive expressions for the exact non-perturbative superpotential in terms of the 1/N expansion of the free energy of the related matrix models.
