description: Magyarországon az 1990-es évektől kezdve az egyes régiók, kistérségek közötti fejlettségbeli különbségek növekedtek, a kormányzati intézkedések nem voltak képesek ezt ellensúlyozni. A 174 magyarországi kistérségből a 33 leghátrányosabb helyzetűben él a lakosság egytizede. Ezek elhelyezkedését belső és külső perifériális állapot jellemzi. Helyzetük javítását az általunk megalkotott szociális zöldenergia program szolgálhatná, melynek gazdasági és társadalmi hatásai főként a legkedvezőtlenebb helyzetű társadalmi csoportokat segíthetnék. Az általunk kidolgozott magyar zöldenergia program forgatókönyve három változatban tartalmazza a gazdasági, társadalmi jellemzőket, valamint ezek költségvetési hatását. Ezek lokális fejlesztő hatására az energiapiaci fejlemények tükrében hosszú távon és növekvő mértékben lehet számítani. ------------------------------------------ Ever since the 1990s, discrepancies between regions and micro-regions have increased, despite governmental attempts to achieve a uniform level of development. In Hungary, one-tenth of the population lives in the 33 most disadvantaged micro-regions out of the 174. They are usually located peripherally, both internally and externally. The social green energy programme we have developed could improve the situation of these micro-regions. Social and economic benefits from the programme would help the most disadvantaged layers of society the most. Our green energy programme scenario described three versions of the economic and social parameters and their budgetary effects. Considering developments in the energy market, the programme would provide increasing impetus to local development for a long time to come.

description: It is shown theoretically that Bose condensation of spin-degenerated exciton-polaritons results in spontaneous buildup of the linear polarization in emission spectra of semiconductor microcavities. The linear polarization degree is a good order parameter for the polariton Bose condensation. If spin-degeneracy is lifted, an elliptically polarized light is emitted by the polariton condensate. The main axis of the ellipse rotates in time due to self-induced Larmor precession of the polariton condensate pseudospin. The polarization decay time is governed by the dephasing induced by the polariton-polariton interaction and strongly depends on the statistics of the condensed state.

description: We present an ab initio stochastic method for calculating thermal properties of a trapped, 1D Bose-gas covering the whole range from weak to strong interactions. Discretization of the problem results in a Bose-Hubbard-like Hamiltonian, whose imaginary time evolution is made computationally accessible by stochastic factorization of the kinetic energy. To achieve convergence for low enough temperatures such that quantum fluctuations are essential, the stochastic factorization is generalized to blocks, and ideas from density-matrix renormalization are employed. We compare our numerical results for density and first-order correlations with analytic predictions.

Thermodynamic uncertainty relation for systems with unidirectional transitions

description: We derive a thermodynamic uncertainty relation (TUR) for systems with unidirectional transitions. The uncertainty relation involves a mixture of thermodynamic and dynamic terms. Namely, the entropy production from bidirectional transitions, and the net flux of unidirectional transitions. The derivation does not assume a steady-state, and the results apply equally well to transient processes with arbitrary initial conditions. As every bidirectional transition can also be seen as a pair of separate unidirectional ones, our approach is equipped with an inherent degree of freedom. Thus, for any given system, an ensemble of valid TURs can be derived. However, we find that choosing a representation that best matches the systems dynamics over the observation time will yield a TUR with a tighter bound on fluctuations. More precisely, we show a bidirectional representation should be replaced by a unidirectional one when the entropy production associated with the transitions between two states is larger than the sum of the net fluxes between them. Thus, in addition to offering TURs for systems where such relations were previously unavailable, the results presented herein also provide a systematic method to improve TUR bounds via physically motivated replacement of bidirectional transitions with pairs of unidirectional transitions. The power of our approach and its implementation are demonstrated on a model for random walk with stochastic resetting and on the Michaelis-Menten model of enzymatic catalysis.

Validation of the synactive theory of development : are body movements in preterm infants signs of stress?
Creators: name: Holsti, Liisa
Publisher: name: University of British Columbia
Year: 2009

description: The synactive theory of development, a widely used theory which has revolutionalized the assessment and treatment of preterm infants in the NICU, consists of five principles which are applied through a model of care. This model, the Newborn Individualized Developmental Care and Assessment Program® (NIDCAP) directs developmental specialists to interpret preterm infant movements either as stress or stability cues. However, limited empirical validation of this dualistic classification system has been reported. The primary aim of this dissertation is to examine the validity of the NIDCAP® by studying the motor reactions of preterm infants in response to a continuum of stressor intensities which range from no stimulus to a painful stimulus. First, along with other valid biobehavioural measures of pain and in infants at 32 weeks corrected gestational age (GA), I examine the frequency of NIDCAP® movements during blood collection. Then, in a within subjects cross-over study (random order), I compare preterm infant biobehavioural pain reactions to responses during a tactile procedure. The secondary aim is to increase the accuracy and specificity of preterm infant pain assessment by determining whether NIDCAP® behaviours are reliable pain indicators and whether these indicators distinguish between pain and stress responses. Of the 26 NIDCAP® stress cues, 14 movements (flex arms and legs, extend arms and legs, hand on face, finger splay, fisting, salute, yawn, sit on air, frown, tongue extension, air plane, eye floating) are associated with intrusive and painful procedures. Finger splay, fisting and hand on face are particularly salient stress cues in infants born at earlier GA (< 30 weeks). Contrary to the NIDCAP®, twitches decrease during the stressor phases in both studies. In addition, in response to painful and tactile procedures, preterm infant body movements are often exaggerated, whereas facial responses are dampened. In conclusion, the dualistic classification of the NIDCAP® needs revision; it also should incorporate alternative explanations of preterm infant movements. The use of body movements as stress response indicators is promising; however, facial reactivity the most specific behavioural pain indicator in preterm infants. Future research is needed to refine further the measurement of stress responses in this vulnerable population.

Tidal fragmentation as the origin of 1I/2017 U1 ('Oumuamua)

description: The first discovered interstellar object (ISO), `Oumuamua (1I/2017 U1) shows a dry and rocky surface, an unusually elongated short-to-long axis ratio $c/a \lesssim 1/6$, a low velocity relative to the local standard of rest ($\sim 10$ km s$^{-1}$), non-gravitational accelerations, and tumbles on a few hours timescale. The inferred number density ($\sim 3.5 \times 10^{13} - 2 \times 10^{15}$ pc$^{-3}$) for a population of asteroidal ISOs outnumbers cometary ISOs by $\geq 10^3$, in contrast to the much lower ratio ($\lesssim 10^{-2}$) of rocky/icy Kuiper belt objects. Although some scenarios can cause the ejection of asteroidal ISOs, a unified formation theory has yet to comprehensively link all `Oumuamua's puzzling characteristics and to account for the population. Here we show by numerical simulations that `Oumuamua-like ISOs can be prolifically produced through extensive tidal fragmentation and ejected during close encounters of their volatile-rich parent bodies with their host stars. Material strength enhanced by the intensive heating during periastron passages enables the emergence of extremely elongated triaxial ISOs with shape $c/a \lesssim 1/10$, sizes $a \sim 100$ m, and rocky surfaces. Although volatiles with low sublimation temperature (such as CO) are concurrently depleted, H$_2$O buried under surfaces is preserved in these ISOs, providing an outgassing source without measurable cometary activities for `Oumuamua's non-gravitational accelerations during its passage through the inner Solar System. We infer that the progenitors of `Oumuamua-like ISOs may be km-sized long-period comets from Oort clouds, km-sized residual planetesimals from debris disks, or planet-size bodies at a few AU, orbiting around low-mass main-sequence stars or white dwarfs. These provide abundant reservoirs to account for `Oumuamua's occurrence rate.

description: Using a ``wall'' of quark point sources, we invert the chirally improved Dirac operator to create an ``incoherent'' collection of quark propagators which originate from all spatial points of the source time slice. The lowest-order NRQCD approximation is used to create heavy-quark propagators from the same wall source. However, since the numerical cost involved in computing such heavy-quark propagators is low, we are able to use a number of source gauge paths to establish coherence between the heavy and light quarks at several spatial separations. The resulting collection of heavy-light meson correlators is analyzed to extract the corresponding mass spectrum.

description: Recently, with the development of deep learning, end-to-end neural network architectures have been increasingly applied to condition monitoring signals. They have demonstrated superior performance for fault detection and classification, in particular using convolutional neural networks. Even more recently, an extension of the concept of convolution to the concept of kervolution has been proposed with some promising results in image classification tasks. In this paper, we explore the potential of kervolutional neural networks applied to time series data. We demonstrate that using a mixture of convolutional and kervolutional layers improves the model performance. The mixed model is first applied to a classification task in time series, as a benchmark dataset. Subsequently, the proposed mixed architecture is used to detect anomalies in time series data recorded by accelerometers on helicopters. We propose a residual-based anomaly detection approach using a temporal auto-encoder. We demonstrate that mixing kervolutional with convolutional layers in the encoder is more sensitive to variations in the input data and is able to detect anomalous time series in a better way.

description: We apply the $C^*$-algebraic formalism of topological T-duality due to Mathai and Rosenberg to a broad class of topological spaces that include the torus bundles appearing in string theory compactifications with duality twists, such as nilmanifolds, as well as many other examples. We develop a simple procedure in this setting for constructing the T-duals starting from a commutative $C^*$-algebra with an action of ${\mathbb R}^n$. We treat the general class of almost abelian solvmanifolds in arbitrary dimension in detail, where we provide necessary and sufficient criteria for the existence of classical T-duals in terms of purely group theoretic data, and compute them explicitly as continuous-trace algebras with non-trivial Dixmier-Douady classes. We prove that any such solvmanifold has a topological T-dual given by a $C^*$-algebra bundle of noncommutative tori, which we also compute explicitly. The monodromy of the original torus bundle becomes a Morita equivalence among the fiber algebras, so that these $C^*$-algebras rigorously describe the T-folds from non-geometric string theory.

description: The filled skutterudite compound SmOs_{4}Sb_{12} was prepared in single crystal form and characterized. The SmOs_{4}Sb_{12} crystals have the LaFe_{4}P_{12}-type structure with lattice parameter a = 9.3085 Angstroms. Specific heat measurements indicate a large electronic specific heat coefficient of ~880 mJ/mol K^{2}, from which an enhanced effective mass m^{*} ~ 170 m_{e} is estimated. The specific heat data also suggest crystalline electric field (CEF) splitting of the Sm^{3+} J = 5/2 multiplet into a Gamma_{7} doublet ground state and a Gamma_{8} quartet excited state separated by 37 K. Electrical resistivity rho(T) measurements reveal a decrease in rho(T) below ~50 K that is consistent with CEF splitting of ~33 K between a Gamma_(7) doublet ground state and Gamma_{8} quartet excited state. Specific heat and magnetic susceptibility measurements display a possible weak ferromagnetic transition at ~2.6 K, which could be an intrinsic property of SmOs_4Sb_{12} or possibly due to an unknown impurity phase.

description: This deliverable is the contribution from Task 6.1 of Aquarius project (Aqua Research Infrastructure Services for the health and protection of our unique, oceans, seas and freshwater ecosystems)
The task 6.1 is included in WP6 on Data Management and Open Science Practices towards serving the targets of the Mission ‘Restore our Ocean and Waters by 2030’, the European Partnership ‘A climate neutral, sustainable and productive Blue Economy’ and associated initiatives and projects. The main aims of WP6 are;
 - Ensure TA project researchers benefit from Copernicus, GEOSS, EMODnet and the European Digital Twin of the Ocean (DTO) initiatives, while making their TA project results available for these initiatives;
 - Plan, develop and operate a federated data management and analytical system for supporting the implementation of an Open Data Strategy; this system will give FAIR access to new data, data products, and scientific knowledge, derived from the TA projects, through a common AQUARIUS Dataflow Dashboard.
This task T6.1 involves analyzing data gaps and data availability. This analysis will aid in formulating the TA Calls for proposals and selecting proposals for each TA call by identifying the most useful and relevant data to collect for each lighthouse region. It is composed of:
 - Analysing knowledge targets of the Mission ‘Restore our Ocean and Waters by 2030’, the European Partnership ‘A climate neutral, sustainable and productive Blue Economy’, the ‘Marine Strategy Framework Directive’ and the ‘Green Deal’.
 - Reviewing existing and known data availability for European waters in RIs, EMODnet, Copernicus, and beyond, for supporting research into the knowledge targets, identifying data gaps that might be included as targets in the TA project Calls.

description: A galgahévízi ökoprojekt gondolata a 80-as évek második felére tekint vissza, majd fokozatosan valósul meg 1989-től kezdődően. Az első lépést a faluban szervezett népfőiskola jelentette, melynek keretében a helyi lakosok ismerkedtek a fenntartható jövővel, majd megalakult a „Galgafarm” Első Magyar Organikus Mezőgazdasági Szövetkezet, amely tevékenységét 1998 óta pénzügyileg is eredményesen folytatja, megteremtve 40-45 család megélhetését. A Galgafarmon tájgazdálkodás folyik, s 50-60 család számára önellátást valósítanak meg élelmiszer-feldolgozó üzemeikben, de termékeiket nyers és feldolgozott formában értékesítik is. Fontos szerepet játszik az épülő galgahévízi ökofalu, mint lakó- és élettér. Minden tevékenység, – az ökofalu is – a természettel való harmóniára törekszik, mindenekelőtt a napenergia maximális hasznosításával, az energiatakarékossággal, az ökológiai lábnyom mérséklése ér¬dekében. Mindez olyan körülmények között valósul meg, amelyek nem kedveznek a fenntarthatóság helyi megvalósításának. ---------------------------------------- The idea of an ecological project in Galgahévíz was born in the second half of the eighties, and was realised gradually, starting in 1989. The very first step was organising an open college in the village, whereby local inhabitants were introduced to the concept of a sustainable future. The Galgafarm First Organic Agricultural Cooperative was then established. Since 1998, the cooperative has been a profitable venture and has enabled 40-45 families to make their living. Galgafarm is engaged in area-specific agriculture. Its food processing plants allow 50-60 families to feed themselves, while both unprocessed and processed products being also commercially sold. The ecovillage being built in Galgahévíz is an important living and community space. All activities in the life of the ecovillage are designed to be environmentally compatible, especially through the utilisation of solar energy to the highest possible degree and through the reduction of energy consumption, in order to reduce the inhabitants’ ecological footprint. All this is being done in a setting where conditions are not favourable for realising sustainability on a local level.

description: We study projective schemes arising from eigenvectors of tensors, called eigenschemes. After some general results, we give a birational description of the variety parametrizing eigenschemes of general ternary symmetric tensors and we compute its dimension. Moreover, we characterize the locus of triples of homogeneous polynomials defining the eigenscheme of a ternary symmetric tensor. Our results allow us to implement algorithms to check whether a given set of points is the eigenscheme of a symmetric tensor, and to reconstruct the tensor. Finally, we give a geometric characterization of all reduced zero-dimensional eigenschemes. The techniques we use rely both on classical and modern complex projective algebraic geometry.
description: The title has been slightly modified. We added two algorithms, testing whether a given configuration of points in the plane is the eigenscheme of some tensor, and reconstructing a tensor from its eigenpoints

description: Magyarországon is teret hódít a biomassza villamos energia termelésére történő felhasználása. A tanulmány Magyarországon képződő szőlővenyige és fanyesedék biomassza-erőművi beszállításának lehetőségeivel foglalkozik. 2009-ben már öt hazai nagyerőműben tüzelnek a környező erdőgazdaságokból származó alapanyagot. Magyarországon rendkívül sok az energetikai célra hasznosítható szőlővenyige és fanyesedék, ami nem kerül hasznosításra, holott ezek erőművi beszállítása – számításaink alapján – 45 km-es szállítási távolság alatt már gazdaságos lehet. A tanulmány hangsúlyozza, hogy az említett melléktermékek erőművi eltüzelése – csekély jövedelemtermelő képessége miatt – jövedelemszerzés helyett inkább a „felesleges” melléktermékektől való megszabadulást, az elhelyezési és megsemmisítési problémák megoldását jelenti, mely költségcsökkenést eredményezhet az egyes gazdaságokban. A szerzők megállapítása szerint a biomasszát mint mellékterméket hasznosító gazdák és települések összefogása ez esetben is elengedhetetlen az erőművekkel szembeni megfelelő alkupozíció kiharcolásához. ------------------------------------------ The production of electricity from biomass is spreading in Hungary as well. This paper looks at the possibilities of supplying vine cane and wood cuttings produced in Hungary to biomass power plants. In 2009, five large Hungarian power plants already use raw material from the nearby managed forests. An extremely large quantity of vine cane and wood cuttings are produced in Hungary which are suitable – but not used – for electricity production, even though our calculations indicate that such supply could be economical if the distance to cover is less than 45 km. Our paper points out that as burning such by-products in a power plant has little potential for profitability, such use could instead serve to enable farms to get rid of the ‘surplus’ by-products and to resolve issues of disposal and destruction. Some farms could achieve a reduction of their costs this way. The authors have found that cooperation between farmers and communities utilising biomass as a by-product is again essential if they are to step up as a viable negotiating partner of the power plants.

description: A mezőgazdasági vállalkozások felszámolásának kedvezőtlen káros hatásai a társadalom széles rétegeit érintik. A kutatás célja az agrárvállalkozások felszámolásához vezető okok elemzése 17 felszámolásra került mezőgazdasági gazdálkodó szervezetben, hogy a tanulságok előmozdítsák a fizetésképtelenség megelőzését és kezelését. A vizsgált vállalkozásokban a likviditási gyorsráta, a saját tőke aránya és az eladósodottság mutatószámainak figyelemmel kísérése a fizetésképtelenség elkerülését segíthette volna. Megállapítható továbbá, hogy alacsony saját tőkével a mezőgazdasági termelés hosszú távon nem folytatható, ezért szükséges, hogy a befektetők a termelés jellegének megfelelő jegyzett tőkével alapítsanak vállalkozást, mert a hitelek felvétele nem pótolja, csupán kiegészíti a saját forrást. A bajba jutott vállalkozásokban a felszámolás megelőzhető, amennyiben a válsághelyzetet időben észlelik, és válságkezelő eszközöket alkalmaznak a vezetők. ------------------------------------------ Negative consequences of the liquidation of agricultural businesses affect large groups of the population. This paper analyses the causes of liquidation in 17 liquidated agricultural businesses in order to derive lessons which may help prevent and address insolvency in others. Monitoring the company’s indices on quick liquidity, own equity ratio and indices of indebtedness can help prevent insolvency. It was also found that on the long term, agricultural operations cannot be conducted with a low level of own equity. Therefore any company established by the investors must have issued capital appropriate for the nature of the agricultural operations, as loans can only be used in addition to, and not instead of own funds. If a business is already in trouble, liquidation may be prevented if the crisis is identified in time and if the managers apply crisis management measures.
Narratives of identity : a poststructural analysis of three deaf women’s life stories

description: This study explored the influence of hearing loss on identity. Phrased in constructionist terms, the research questions guiding this study were how do culturally Deaf women perceive the influence of hearing loss as they construct their identities? And how do they incorporate, resist, and/or reject various cultural discourses as they go about the creative act of constructing their identities? The participants were three adult women with prelingual hearing losses. All three participants were raised in hearing-oriented environments where auditory/oral communication was used and as adults identified as culturally Deaf. A collaborative narrative method was used and in-depth interviews that elicited life stories were conducted with the participants. Sign language was used during the interviews. The interviews were videotaped, then interpreted to spoken English by the researcher, and then subsequently transcribed. The research interviews provided rich, descriptive data that were used to create a narrative summary of each participant's life story. The researcher collaborated with each participant around the representation of her life story in narrative form. The narrative summaries illustrate the complex, textured, and multilayered ways in which each of the participants constructed identity in their life stories, where identities competed, co-existed, and overlapped. In addition, drawing on poststructural ideas the researcher analyzed four cultural discourses at work in the participants' narratives: discourses of normalcy, discourses of difference, discourses of passing, and Deaf cultural discourses. It was found that a binary relationship existed between discourses of normalcy and discourses of difference leading to the construction of identities based on opposites. These identities were positioned in a binary relationship where one side of the binary was privileged and the opposite was "othered", e.g., hearing/deaf, and Deaf/deaf. However, the poststructural narrative analysis demonstrated that these categories were not fixed, but rather, that hearing status was a complex, unstable identity category, reflecting shifting identities and positionalities. The findings are discussed in relation to empirical literature on deafness and identity. The study concludes with suggestions for professionals, with a discussion of methodological implications, and with a discussion of future research possibilities.
Impact of positivity and complete positivity on accessibility of Markovian dynamics

description: We consider a two-dimensional quantum control system evolving under an entropy-increasing irreversible dynamics in the semigroup form. Considering a phenomenological approach to the dynamics, we show that the accessibility property of the system depends on whether its evolution is assumed to be positive or completely positive. In particular, we characterize the family of maps having different accessibility and show the impact of that property on observable quantities by means of a simple physical model.

description: Measurement schemes of Majorana zero modes (MZMs) based on quantum dots (QDs) are of current interest as they provide a scalable platform for topological quantum computation. In a coupled qubit-QD setup we calculate the dependence of the charge of the QD and its differential capacitance on experimentally tunable parameters for both 2-MZM and 4-MZM measurements. We quantify the effect of noise on the measurement visibility by considering $1/f$ noise in detuning, tunneling amplitudes or phase. We find that on- or close-to-resonance measurements are generally preferable and predict, using conservative noise estimates, that noise coupling to the QDs is not a limitation to high-fidelity measurements of topological qubits.

description: We calculate the cross section of J/psi plus prompt-photon inclusive production in gamma gamma collisions at next-to-leading order within the factorization formalism of nonrelativistic quantum chromodynamics (NRQCD) focusing on direct photoproduction. Apart from direct J/psi production, we also include the feed-down from directly-produced chi_{cJ} and psi' mesons. We discuss the analytical calculation, in particular the treatment of the various types of singularities and the NRQCD operator renormalization, in some detail. We present theoretical predictions for the future e^+e^- linear collider TESLA, taking into account both brems- and beamstrahlung.

description: We analyse TESS photometry of DMPP-1 (HD 38677; TIC 66560666), a nearby F8V star hosting hot super-Earth planets and a warm Neptune. Using the Transit Least Squares algorithm and other methods we find a transit signal at $P=3.2854^{+0.0032}_{-0.0025}$ d with depth 87$^{+25}_{-30}$ ppm and false alarm probability 1.6%. This is shallower than hitherto published TESS discoveries. The 3.285 d signal is recovered for several, but not all, methods for detrending stellar astrophysical variability. Further observations are needed to improve the significance of the detection. If this transit were due to an Earth-like rocky planet it would have been detected in the RV data, but it is not. The TESS data cover seven individual transits, one of which is consistent with zero depth. The insolation of the putative planet is $990 {\rm S_{\oplus}}$, typical of fluxes experienced by the three known catastrophically disintegrating exoplanets (CDEs). The transits can be self-consistently attributed to a CDE with a mass below the RV detection threshold. We searched for transits of the known RV planets, finding null results and detection thresholds of $< 100$ ppm, which we quantify for each. The DMPP-1 planetary system was discovered as a consequence of circumstellar gas attributed to ablation of hot planets. The RV planets may have been ablated to near-pure iron cores. We place limits on the orbital inclinations of the RV planets where the expected transit depth exceeds the detection threshold. If the 3.2854 day transit detection is confirmed, e.g. with CHEOPS photometry, DMPP-1 would be a first-rate target for JWST spectroscopy.

description: The `O-rich AGB sequence' is a sequence of colours describing the location of O-rich AGB stars in the IRAS two-colour diagram [12]--[25] vs [25]--[60]. We propose an evolutionary scenario for this sequence in which all stars, independent of their progenitor mass, start the AGB phase in the blue part of the `O-rich AGB sequence' and then evolve toward redder colors, although only the more massive stars would reach the very end of the `O-rich AGB sequence'. The sources located in the blue part of the sequence are mainly Mira variables, whose mean period is increasing with the IRAS colours. Most of them will evolve into O-rich Type II (and III) Planetary Nebulae. Part of the stars located in the red part of the sequence will change their chemical composition from O-rich to C-rich during their evolution in the AGB phase, and might evolve into C-rich Type II Planetary Nebulae. Hot bottom burning may prevent the conversion to carbon stars of the rest of sources located in the red part of the sequence and they will end up as N-rich Type I Planetary Nebulae.
