description: We present the result of a decomposition of the 2dFGRS galaxy overdensity field into an orthonormal basis of spherical harmonics and spherical Bessel functions. Galaxies are expected to directly follow the bulk motion of the density field on large scales, so the absolute amplitude of the observed large-scale redshift-space distortions caused by this motion is expected to be independent of galaxy properties. By splitting the overdensity field into radial and angular components, we linearly model the observed distortion and obtain the cosmological constraint Omega_m^{0.6} sigma_8=0.46+/-0.06. The amplitude of the linear redshift-space distortions relative to the galaxy overdensity field is dependent on galaxy properties and, for L_* galaxies at redshift z=0, we measure beta(L_*,0)=0.58+/-0.08, and the amplitude of the overdensity fluctuations b(L_*,0) sigma_8=0.79+/-0.03, marginalising over the power spectrum shape parameters. Assuming a fixed power spectrum shape consistent with the full Fourier analysis produces very similar parameter constraints.

description: The super-Kamiokande collaboration have used multi-ring events to discriminate between the $ν_μ--> ν_τ$ and $ν_μ--> ν_s$ solutions to the atmospheric neutrino anomaly. We show that the effect of systematic uncertainties in cross sections are so significant that the usefulness of multi-ring data to distinguish between these two solutions is doubtful.

description: Energy requirement increases rapidly in agriculture due to the increase in mechanization. The aim of the present study is to evaluate the energy use efficiency of silage maize under three different tillage practices (conventional, reduced, no-tillage) combined with four different irrigation levels (full and three deficit irrigations). The no-tillage and reduced tillage practices provided savings in input energy at the rate of 17.4 and 9.1%, respectively compared to the conventional tillage. The highest silage yields in all irrigation levels were obtained in the no-tillage practice. Therefore, in full and deficit irrigated silage maize, the highest energy ratio, energy productivity and net energy and the lowest specific energy values were manifested in the no-tillage practice. Energy rates in the no-tillage practice were higher by 34.2 and 22.9% than the conventional and the reduced tillage practices, respectively. Moreover, the direct and non-renewable energy requirements were the lowest in the no-tillage practice. In conclusion, the fully-irrigated no-tillage practice can be recommended to obtain the highest energy use ratio and productivity. However, no-tillage irrigated with up to 50% less water amount could be a better alternative for areas with a water shortage by improving the energy use ratio with better water and fuel savings.

Material examined.
Bulgaria • 2 ♂♂, 1 ♀, Pirin Mountains, Hut Kamenitsa, 1800 m a. s. l., 15. 06. 1988, P. Beron leg.
Taxonomic notes.
Observations under the microscope of the studied material have shown several previously unknown features not mentioned in its original description (Condé 1956, 1966). The antennae have 27 antennomeres in a 3.8 mm female, and 25 in 3.95 mm and 4.2 mm males. The apical antennomere has four simple spheroidal olfactory chemoreceptors on the cupuliform organ. A large bacilliform sensillum is present on the third antennomere in tergal position (between b-c macrosetae). Notal tergites bear microdenticles, and the clothing setae are either smooth or have a distal tiny barb (Fig. 7 a). The marginal setae are slightly longer and thicker than clothing setae, with a few bars on distal half to two-thirds. The pronotal macrosetae have a few thin tiny barbs on the distal half, with the longest lp macrosetae with one or two thin tiny barbs at the distal position. No trochanteral setae were observed in any of the specimens studied.
The male urosternite I (Fig. 7 b) features slightly spherical appendages, each with an apical field containing ≤ 40 glandular a 1 setae; a continuous posterior field of ~ ≤ 240 g 1 glandular setae arranged in 7–9 rows.
Remarks.
New record for Bulgaria.
Habitat and distribution.
A soil-dwelling species that inhabits high altitudes. It is known from two localities in the Austrian Alps (Condé 1954, 1966) and a single locality in the Pirin Mountains of Bulgaria.

description: Here we report our discovery of a band of blue luminescence (BL) in the Red Rectangle (RR) nebula. This enigmatic proto-planetary nebula is also one of the brightest known sources of extended red emission as well as of unidentified infra-red (UIR) band emissions. The spectrum of this newly discovered BL is most likely fluorescence from small neutral polycyclic aromatic hydrocarbon (PAH) molecules. PAH molecules are thought to be widely present in many interstellar and circumstellar environments in our galaxy as well as in other galaxies, and are considered likely carriers of the UIR-band emission. However, no specific PAH molecule has yet been identified in a source outside the solar system, as the set of mid-infra-red emission features attributed to these molecules between the wavelengths of 3.3 micron and 16.4 micron is largely insensitive to molecular sizes. In contrast, near-UV/blue fluorescence of PAHs is more specific as to size, structure, and charge state of a PAH molecule. If the carriers of this near-UV/blue fluorescence are PAHs, they are most likely neutral PAH molecules consisting of 3-4 aromatic rings such as anthracene (C14H10) and pyrene (C16H10). These small PAHs would then be the largest molecules specifically identified in the interstellar medium.

description: Trade of agricultural and food products on world market is protected by very rigid standards in order to protect health and welfare of consumers, animals and plans, consistent to number of international agreement. Standards can be often used as screen for imposing nontariff barriers with the purpose to preserve economic interest of companies from developed countries. In this process export from undeveloped countries usually is seriously damaged. Relevant economic literature is discussing role of World trade organisation with special emphasis on negotiations on international level, partly neglecting role of other forms of provisions that can also have strong influence on quality and structure of foreign trade of agricultural and food products. This paper provides an overview of raise and development of private food safety and quality standards and analysis their increasing role on international trade of agricultural and food products. Most countries, especially those on low level of development, evaluate process of outspreading and richness of standards as an obstacle for export increase. Paper therefore explains positive effects that standards can have on international trade of agricultural and food products.

description: We study the optical reflectivity of three-dimensional (3D) photonic band gap crystals with increasing thickness. The crystals consist of GaAs plates with nanorod arrays that are assembled by an advanced stacking method into high-quality 3D woodpile structures. We observe intense and broad reflectivity peak with stop bands that correspond to a broad gap in the photonic band structures. The maximum reflectivity quickly reaches high values even for a few crystal layers. Remarkably, the bandwidth of the stop bands hardly decreases with increasing crystal thickness, in good agreement with FDTD simulations. This behavior differs remarkably from the large changes observed earlier in weakly interacting 3D photonic crystals. The nearly constant bandwidth and high reflectivity are rationalized by multiple Bragg interference that occurs in strongly interacting photonic band gap crystals, whereby the incident light scatters from multiple reciprocal lattice vectors simultaneously, in particular from oblique ones that are parallel to a longer crystal dimension and thus experience hardly any finite size effects. Our new insights have favorable consequences for the application of 3D photonic band gap crystals, notably since even thin structures reveal the full band gap functionality, including devices that shield quantum bits from vacuum fluctuations.

description: Continuous spectroscopic measurements of a strongly driven superconducting qubit by means of a high-quality tank circuit (a linear detector) are under study. Output functions of the detector, namely, a spectrum of voltage fluctuations and an impedance, are expressed in terms of the qubit spectrum and magnetic susceptibility. The nonequilibrium spectrum of the current fluctuations in the qubit loop and the linear response function of the driven qubit coupled to a heat bath are calculated with Bloch-Redfield and rotating wave approximations. Backaction effects of the qubit on the tank and the tank on the qubit are analyzed quantitatively. We show that the voltage spectrum of the tank provides detailed information about a frequency and a decay rate of Rabi oscillations in the qubit. It is found that both an efficiency of spectroscopic measurement and measurement-induced decoherence of the qubit demonstrate a resonant behaviour as the Rabi frequency approaches the resonant frequency of the tank. We determine conditions when the spectroscopic observation of the Rabi oscillations in the flux qubit with the tank circuit can be considered as a weak continuous quantum measurement.

description: In the large momentum transfer limit, generalized parton distributions can be calculated through a QCD factorization theorem which involves perturbatively-calculable hard kernels and light-cone parton distribution amplitudes of hadrons. We illustrate this through the $H_q(x,ξ,t)$ distribution for the pion and proton, presenting the hard kernels at leading order. As a result, experimental data on the generalized parton distributions in this regime can be used to determine the functional form of the parton distribution amplitudes which has thus far been quite challenging to obtain. Our result can also be used as a constraint in phenomenological GPD parametrizations.

Cause + Effect : Rendering the Invisible

Publisher: name: The University of British Columbia

description: Architecture is inherently political and has the potential to be used as a form of agency for those affected by conflicts. The most affected populations of both environmental and human conflict are the millions of displaced people globally. These groups are hosted in other countries in varying conditions, from host families to tent shelters in refugee camps. The establishment of refugee camps are often adjacent or at a distance from major cities or along International borders. The birth of a refugee camp is based on pure necessity and creates a problematic condition for transitioning into permanent settlements. Unfortunately, many refugee camps arise in areas of internal conflict or zones of environmental risk. The advancement of design tools and technology allow Architects to investigate areas of severe conflict or are inaccessible for field studies to provide site-specific humanitarian design proposals. Host countries of refugee populations are responsible for their treatment. Considering this, the project studies the political complexities of Lebanon as a host country of Syrian refugees. Their national policies are clear tools of geo-political control and create unsafe living conditins for this vulnerable population seeking refuge in their country. As a designer, we have the capacity to create linkages between different sources of information or render the invisible forces that effect built environments. The project uses this research scenerio of informal Syrian refugee camps in Lebanon, to provide an example as to how foreign designers can highlight complex issues and use our skills to create more responsive immediate design strategies.
Cross-field chaotic transport of electrons by ExB electron drift instability in Hall thruster

description: A model calculation is presented to characterize the anomalous cross-field transport of electrons in a Hall thruster geometry. The anomalous nature of the transport is attributed to the chaotic dynamics of the electrons arising from their interaction with fluctuating unstable electrostatic fields of the electron cyclotron drift instability that is endemic in these devices. Electrons gain energy from these background waves leading to a significant increase in their temperature along the perpendicular direction $T_\perp / T_\parallel \sim 4$ and an enhanced cross-field electron transport along the thruster axial direction. It is shown that the wave-particle interaction induces a mean velocity of the electrons along the axial direction, which is of the same order of magnitude as seen in experimental observations.

description: We review and extend earlier work that uses the AdS/CFT correspondence to relate the black hole-black string transition of gravitational theories on a circle to a phase transition in maximally supersymmetric 1+1-dimensional SU(N) gauge theories at large N, again compactified on a circle. We perform gravity calculations to determine a likely phase diagram for the strongly coupled gauge theory. We then directly study the phase structure of the same gauge theory, now at weak 't Hooft coupling. In the interesting temperature regime for the phase transition, we may reduce the 1+1-dimensional theory to a 0+1-dimensional bosonic theory, which we solve using Monte Carlo methods. We find strong evidence that the weakly coupled gauge theory also exhibits a black hole-black string like phase transition in the large N limit. We demonstrate that a simple Landau-Ginzburg like model describes the behaviour near the phase transition remarkably well. The weak coupling transition appears to be close to the cusp between a first order and a second order transition.

description: We propose the RES-NOVA project which will hunt neutrinos from core-collapse supernovae (SN) via coherent elastic neutrino-nucleus scattering (CE$ν$NS) using an array of archaeological lead (Pb) based cryogenic detectors. The high CE$ν$NS cross-section on Pb and the ultra-high radiopurity of archaeological Pb enable the operation of a high statistics experiment equally sensitive to all neutrino flavors with reduced detector dimensions in comparison with existing Neutrino Observatories, and easy scalability to larger detector volumes. RES-NOVA is planned to operate according to three phases with increasing detector volumes: (60 cm)$^3$, (140 cm)$^3$, and ultimately 15$\times$(140 cm)$^3$. It will be sensitive to SN bursts up to Andromeda with 5$σ$ sensitivity with already existing technologies and will have excellent energy resolution with $1$ keV threshold. Within our Galaxy, it will be possible to discriminate core-collapse SNe from black hole forming collapses with no ambiguity even in the first phase of RES-NOVA. The average neutrino energy of all flavors, the SN neutrino light curve, and the total energy emitted in neutrinos can potentially be constrained with a precision of few $\%$ in the final detector phase. RES-NOVA will be sensitive to flavor-blind neutrinos from the diffuse SN neutrino background with an exposure of $620$ ton $\cdot$ y. The proposed RES-NOVA project has the potential to lay down the foundations for a new generation of neutrino telescopes, while relying on a very simple technological setup

title: Supporting the Discoverability of Open Educational Resources: on the Scent of a Hidden Treasury
Creators: name: Cortinovis, Renato Mario
Publisher: name: The Open University
Year: 2020

description: Open Educational Resources (OERs), now available in large numbers, have a considerable potential to improve many aspects of society, yet one of the factors limiting this positive impact is the difficulty to discover them. This thesis investigates and proposes strategies to better support educators in discovering OERs. The literature suggests that the effectiveness of existing search systems, including for OER discovery, could be improved by supporting users, such as teachers, in carrying out more exploratory search activities closer to their existing methods of working. Hence, a preliminary taxonomy of OER-related search tasks was produced, based on an analysis of the literature, interpreted through Information Foraging Theory. This taxonomy was empirically evaluated to preliminarily identify a set of search tasks that involve finding other OERs similar to one that has already been identified, a process that is generally referred to as Query By Example (QBE). Following the Design Science Research methodology, three prototypes to support as well as to refine those tasks were iteratively designed, implemented, and evaluated involving an increasing number of educators in usability oriented studies. The resulting high-level and domain-oriented blended search/recommendation strategy transparently replicates Google searches in specialized networks, and identifies similar resources with a QBE strategy. It makes use of a domain-oriented similarity metric based on shared alignments to educational standards, and clusters results in expandable classes of comparable degrees of similarity. The summative evaluation shows that educators do appreciate this strategy because it is exploratory and – balancing similarity and diversity – it supports their high-level tasks, such as lesson planning and personalization of education. Finally, potential barriers and opportunities for the uptake of OER discovery tools were investigated in a structured interview study with experts from the OER field. Identified issues included how to work across multiple OER portals, variability in the use of metadata and how to align with the working practices of teachers. The findings of the thesis can be used to inform the research and development of methods and tools for OER discovery as well as their deployment to serve the needs of educators.

description: The effectiveness of plant–soil synergies is largely modulated by interaction between cultivar and rhizosphere microbiome. We evaluated the agronomic performance of six durum wheat cultivars, in two semi-arid locations in Tunisia that differed in their irrigation water salinity: S1 (6 dS m−1) and S2 (12 dS m−1). The two-consecutive-year field experiments assessed the effects of the microbial biomass carbon (MBC), leaf phosphorus (LP) and rhizosphere phosphorus (P) on the grain yield (GY) and yield components at tillering and flowering stages. Overall, in saline conditions, cultivars differed in above- and below-ground traits, particularly, with tolerant cultivars presenting relatively greater MBC, P and LP. Furthermore, in S2, GY positively correlated with MBC (r = 0.69), LP (r = 0.80) and P (r = 0.79). Additionally, in S2, MBC positively correlated with P (r = 0.87) and LP (r = 0.85) at flowering. This result was further confirmed by multiple linear regression (step-wise) analysis, which revealed that MBC and LP were the determinant components of GY variability under S2. The present study demonstrates that LP and soil P are mandatory for improving the management of durum wheat. Salinity tolerance was largely affected by the cultivars’ rhizosphere MBC.

description: A supervised feedforward artificial neural network (ANN) trained with backpropagation algorithms, along with multiple linear regression (MLR) model, was applied to predict the biological yield (BY) of grass pea. For this purpose, a four-year study (2008–2012) was carried out under rainfed conditions in three dryland stations in Iran, and a panel of 12 grass pea genotypes were evaluated for agronomic and phonologic characters. Stepwise regression (SWR) and principal component analysis (PCA) were employed to evaluate 15 input parameters. To discover the optimum ANN structure, different training algorithms, transfer functions, number of hidden layers and neuron in each layer were studied and optimized using Taguchi’s method. The multilayer perceptron (MLP) model with tangent sigmoid (tagsig) transfer function, Levenberg–Marquardt learning algorithm, and two hidden layers was identified as the best model to predict the BY of the grass pea. The sensitivity analysis of inputs revealed that seed yield (SY) followed by thousand seed weight (TSW) and number of days to maturity (NDM), respectively, were the most influential factors in predicting BY in both models. According to the adjusted ANN model, early flowering genotypes with long maturity and high TSW should be considered as the best model for enhancing BY in breeding programs.

description: We introduce the First Light And Reionisation Epoch Simulations (FLARES), a suite of zoom simulations using the EAGLE model. We resimulate a range of overdensities during the Epoch of Reionisation (EoR) in order to build composite distribution functions, as well as explore the environmental dependence of galaxy formation and evolution during this critical period of galaxy assembly. The regions are selected from a large $(3.2 \;\mathrm{cGpc})^{3}$ parent volume, based on their overdensity within a sphere of radius $14\,h^{-1}\;\mathrm{cMpc}$. We then resimulate with full hydrodynamics, and employ a novel weighting scheme that allows the construction of composite distribution functions that are representative of the full parent volume. This significantly extends the dynamic range compared to smaller volume periodic simulations. We present an analysis of the galaxy stellar mass function (GSMF), the star formation rate distribution function (SFRF) and the star forming sequence (SFS) predicted by \flares, and compare to a number of observational and model constraints. We also analyse the environmental dependence over an unprecedented range of overdensity. Both the GSMF and the SFRF exhibit a clear double-Schechter form, up to the highest redshifts ($z = 10$). We also find no environmental dependence of the SFS normalisation. The increased dynamic range probed by FLARES will allow us to make predictions for a number of large area surveys that will probe the EoR in coming years, such as WFIRST and Euclid.

description: Control State money expenditure, especially in developed countries, is democratic heritage based on principles that, through accredited and unbiased institutions, citizens have the possibility to get insight into all aspects of taxpayers’ money expenditure. In that sense, public expenditure supervision represents an activity directed towards decrease in the costs of functioning of the state and its entities. State supervision comprises three segments, as follows: control, inspection, and state audit. Control is continuous every day supervision by state employees, usually internal. Inspection is additional external control by the state. State audit has the function of public expenditure inspection. It evaluates how economical, efficient, and effective state budget institutions are. In this text, we deal with the most significant aspects of public finance supervision through:internal control, internal state audit, and administrative, accounting-court and parliamentary control. All these forms intertwine thus creating one integrating supervision system of public finance, with one clear goal – decrease in public expenditure and less expensive state.

description: We analytically prove that the existence of the delta-function singularity in the chirally-odd twist-3 distribution $e(x)$ of the nucleon is inseparably connected with the nonvanishing quark condensate as a signal of the spontaneous chiral symmetry breaking of the QCD vacuum. This singularity in $e(x)$, which would be observed as a sizable violation of the 1st moment sum rule, is then interpreted as giving a very rare case that the nontrivial vacuum structure of QCD manifests in an observable of a localized QCD excitation, i.e. the nucleon.

description: Impact of price changes and income changes in the intensity of demand, and thus the Company is not the same and is not equal for all companies in different market structures. The aim of the empirical research of elasticity of demand and its impact on the income of companies in different market structures is that, using different economic methods obtain relevant information about the tested categories, based on which companies can plan their economic development. However, regardless of all the difficulties of theoretical and practical nature, the analysis of the concept of flexibility some scientific circles, aim of this work is just to show the theoretical role and importance of the concept of elasticity of demand on the formation of the income of companies in full and limited competition, monopoly and oligopoly. The company's business policy, among other things must take into account changes in the sales and income that occur because of the effect of price changes on the changes in the amount of sales products. Coeffcient elasticity of demand is especially important for the policy of price because the company provide the basic elements for planning and realization of the maximum total revenue.

description: This work analyses two novels by the Afro-American novelist Toni Morrison by employing critical tools from diverse fields such as structuralism, narratology, psychoanalysis and philosophy. The Introduction posits some problems in relation to the analysis of the concepts of race and gender from a feminia perspective. Chapter 1 is dedicated to story and memory in Beloved. Chapter 2 analyses narration and the ‘jazzy’ prose style Jazz, Chapter 3 is an interpretation of the time-space and power concepts as discussed by Heidegger, Foucault, and Bakhtin. The conclusion summarises in short the dissertation.
Stochastic Allen-Cahn Equation with Logarithmic Potential

description: We prove existence and uniqueness of a solution for the stochastic Allen-Cahn equation with logarithmic potential and multiplicative Wiener noise, under homogeneous Neumann boundary condition. The existence of a solution is obtained in the variational sense by means of an approximated equation involving a Yosida regularization of the nonlinearity. The noise is assumed to vanish at the extremal points of the physical relevant domain and to satisfy a suitable Lipschitz-continuity property, allowing to prove uniform estimates of the approximated solution. The passage to the limit is then carried out and continuous dependence on the initial datum of the solution is verified. Under an additional assumption, the existence of an analytically strong solution is proved. Finally, estimates for the derivatives of the logarithmic potential are derived, in view of the study of an optimal control problem associated to the stochastic Allen-Cahn equation.

description: The poly-γ-glutamic acid super-absorbent polymer (γ-PGA SAP) is an environmentally friendly material. Five different γ-PGA SAPs contents based on weight, including 0% (CK), 0.05% (T1), 0.10% (T2), 0.15% (T3), and 0.20% (T4), were added to the soil in this study. The results showed that cumulative infiltration decreased by 32.4% (T1), 39.2% (T2), 51.0% (T3), and 52.0% (T4) at 90 min and the field capacity was increased by 18.7% (T1), 26.0% (T2), 37.8% (T3), and 58.3% (T4) compared with the CK. The cumulative evaporation of the different treatments with γ-PGA SAPs was 17.1% (T1), 23.5% (T2), 24.4% (T3), and 25.3% (T4) higher than that of the CK at the end of the evaporation experiment. The evaporation experiment lasted 96 h (CK), 132 h (T1), 144 h (T2), 180 h (T3), and 312 h (T4) to progress from field capacity to a soil water content of 10%. Adding γ-PGA SAPs to the soil significantly increase the water-stable aggregate content below 0.25 mm when the γ-PGA SAP addition exceeded 0.10%. So reasonable utilization of γ-PGA SAP can improve water use efficiency and improve soil structure in semi-arid areas.

description: Graduate education plays a pivotal role in fostering intellectual advancement, personal growth, and societal development. While traditionally valued for academic rigor and career preparation, this study explored the deeper, often overlooked joy that graduate students derive from their academic journeys. Employing a qualitative-descriptive research design, the study focused on the lived experiences of Master of Arts in Nursing (MAN) students through semi-structured interviews with twelve purposively selected participants. Content analysis revealed four emergent themes that encapsulated the essence of joy in graduate education: (1) Intellectual Expansion and Curiosity, (2) Personal Growth and Self-Discovery, (3) Academic and Professional Milestones, and (4) Community and Collaborative Learning. Participants shared how their educational experiences fostered critical thinking, built resilience, affirmed their scholarly identity, and cultivated meaningful academic relationships. These narratives highlight the multifaceted benefits of graduate education beyond measurable outputs, emphasizing the importance of emotional fulfillment and intellectual engagement. The findings advocate for institutional policies that promote a holistic and supportive academic environment through mentorship, well-being initiatives, research opportunities, and inclusive learning communities. As global education systems evolve to meet complex societal demands, understanding and nurturing the intrinsic joys of learning can enhance student satisfaction, motivation, and success. This study calls for a reimagining of graduate education as a transformative experience that not only equips learners with professional competencies but also ignites lifelong curiosity, purpose, and connection.
