description: The progress in our understanding of several aspects of turbulent Rayleigh-Benard convection is reviewed. The focus is on the question of how the Nusselt number and the Reynolds number depend on the Rayleigh number Ra and the Prandtl number Pr, and on how the thicknesses of the thermal and the kinetic boundary layers scale with Ra and Pr. Non-Oberbeck-Boussinesq effects and the dynamics of the large-scale convection-roll are addressed as well. The review ends with a list of challenges for future research on the turbulent Rayleigh-Benard system.

description: The InterPED project aims to revolutionize the concept of Positive Energy Districts (PEDs) by fostering energy sector integration, demand-side flexibility, and citizen engagement while maximizing the use of renewable energy sources (RES). This deliverable, D3.3: Project Requirements, Platform Architecture, and KPIs, outlines the methodologies, requirements, and architectural principles necessary for achieving these goals, providing a strong foundation for subsequent development and deployment phases.

The report highlights a five-step methodology for designing the InterPED platform, focusing on PED analysis, KPI definition, service development, tool integration, and platform interoperability. The platform architecture emphasizes compliance with leading frameworks like SGAM (Smart Grid Architecture Model) and COSMAG, ensuring modularity, scalability, and interoperability. Additionally, it integrates emerging technologies such as cloud-based microservices, real-time analytics, and OpenAPI standards to support robust energy solutions.

Four diverse pilot sites in Spain, the UK, Switzerland, and Romania serve as testbeds for validating the platform's feasibility across varied geographies and energy systems. Each pilot addresses unique objectives, such as optimizing energy self-consumption, enabling life cycle cost analysis, and fostering active community participation in demand response strategies.

The platform's key innovations include a modular architecture supporting real-time data ingestion and analytics, cross-vector optimization for energy management, and tools for user-centric engagement. Over 35 Key Performance Indicators (KPIs) were defined to evaluate technical, financial, environmental, and social impacts, ensuring a comprehensive assessment framework.

By integrating lessons from prior EU projects and aligning with international energy standards, this deliverable sets the stage for the development of an interoperable, scalable, and sustainable energy ecosystem that facilitates the transition to decarbonized PEDs.

This document serves as a cornerstone for subsequent technical development and validation efforts, paving the way for widespread adoption of PED concepts across Europe and beyond.

description: Based on measurements of nonlinear second sound resonances in a high-quality resonator, we have observed a steady-state wave energy cascade in He II involving a flux of energy through the spectral range towards high frequencies. We show that the energy balance in the wave system is nonlocal in K-space and that the frequency scales of energy pumping and dissipation are widely separated. The wave amplitude distribution follows a power law over a wide range of frequencies. Numerical computations yield results in agreement with the experimental observations. We suggest that second sound cascades of this kind may be useful for model studies of acoustic turbulence.

description: We report on the selectivity to spin in a drag measurement. This selectivity to spin causes deep minima in the magnetodrag at odd filling factors for matched electron densities at magnetic fields and temperatures at which the bare spin energy is only one tenth of the temperature. For mismatched densities the selectivity causes a 1/B periodic oscillation, such that negative minima in the drag are observed whenever the majority spins at the Fermi energies of the two-dimensional electron gases are antiparallel, and positive maxima whenever the majority spins at the Fermi energies are parallel.
Transport Equation Approach to Calculations of Hadamard Green functions and non-coincident DeWitt coefficients

description: Building on an insight due to Avramidi, we provide a system of transport equations for determining key fundamental bi-tensors, including derivatives of the world-function, σ(x,x'), the square root of the Van Vleck determinant, Δ^{1/2}(x,x'), and the tail-term, V(x,x'), appearing in the Hadamard form of the Green function. These bi-tensors are central to a broad range of problems from radiation reaction to quantum field theory in curved spacetime and quantum gravity. Their transport equations may be used either in a semi-recursive approach to determining their covariant Taylor series expansions, or as the basis of numerical calculations. To illustrate the power of the semi-recursive approach, we present an implementation in \textsl{Mathematica} which computes very high order covariant series expansions of these objects. Using this code, a moderate laptop can, for example, calculate the coincidence limit a_7(x,x) and V(x,x') to order (σ^a)^{20} in a matter of minutes. Results may be output in either a compact notation or in xTensor form. In a second application of the approach, we present a scheme for numerically integrating the transport equations as a system of coupled ordinary differential equations. As an example application of the scheme, we integrate along null geodesics to solve for V(x,x') in Nariai and Schwarzschild spacetimes.

description: Let $G$ be a connected compact Lie group, and let $M$ be a connected Hamiltonian $G$-manifold with equivariant moment map $ϕ$. We prove that if there is a simply connected orbit $G\cdot x$, then $π_1(M)\congπ_1(M/G)$; if additionally $ϕ$ is proper, then $π_1(M)\congπ_1(ϕ^{-1}(G\cdot a))$, where $a=ϕ(x)$. We also prove that if a maximal torus of $G$ has a fixed point $x$, then $π_1(M)\congπ_1(M/K)$, where $K$ is any connected subgroup of $G$; if additionally $ϕ$ is proper, then $π_1(M)\congπ_1(ϕ^{-1}(G\cdot a))\congπ_1(ϕ^{-1}(a))$, where $a=ϕ(x)$. Furthermore, we prove that if $ϕ$ is proper, then $π_1\big(M/\Gh\big)\congπ_1\big(ϕ^{-1}(G\cdot a)/\Gh\big)$ for all $a\inϕ(M)$, where $\Gh$ is any connected subgroup of $G$ which contains the identity component of each stabilizer group. In particular, $π_1(M/G)\congπ_1(ϕ^{-1}(G\cdot a)/G)$ for all $a\inϕ(M)$.

The Posterior Distribution of sin(i) Values For Exoplanets With M_T sin(i) Determined From Radial Velocity Data

description: Radial velocity (RV) observations of an exoplanet system giving a value of M_T sin(i) condition (i.e. give information about) not only the planet's true mass M_T but also the value of sin(i) (where i is the orbital inclination angle). Thus the value of sin(i) for a system with any particular observed value of M_T sin(i) cannot be assumed to be drawn randomly from a uniform distribution between zero and unity (corresponding to an isotropic i distribution). The actual distribution from which it is drawn depends on the intrinsic distribution of M_T for the exoplanet population being studied. We give a simple Bayesian derivation of this relationship and apply it to several "toy models" for the (currently unknown) intrinsic distribution of M_T. The results show that the effect can be an important one. For example, even for simple power-law distributions of M_T, the median value of sin(i) in an observed RV sample can vary between 0.25 and 0.71 (as compared to the 0.5 value for an isotropic i distribution) for indices of the power-law in the quite plausible range between -2 and -0.5, respectively. Over the same range of indicies, the 95% confidence upper bound on M_T ranges from 4.5 to 400 times larger than M_T sin(i), respectively, due to sin(i) uncertainty alone. More complex, but still simple and plausible, distributions of M_T yield still more complicated and less intuitive $sin(i)$ distributions. In particular, if the M_T distribution contains any characteristic mass scale M_c, the sin(i) distribution will depend on the ratio of M_T sin(i) to $M_c$, often in a non-trivial way. Our qualitative conclusion is that RV studies of exoplanets, both individual objects and statistical samples, should regard the sin(i) factor as more than a "numerical constant of order unity" with simple and well understood statistical properties.

Entrepreneurship Education and Career Paths: Evidence From An Entrepreneurship Centre

Subjects: subject: 150304 Entrepreneurship
subject: FOS: Economics and business

description: Entrepreneurship education (EE) has become increasingly important for universities. As part of a programme equipping students with the capabilities to start and develop businesses, alongside a broader portfolio of workplace skills, EE is seen as critical at individual and collective levels. Despite these objectives, both models and mediums of EE have seen increased debate, particularly as the entrepreneurship agenda migrates beyond the business school. One prevalent question for EE is which method of delivery is most effective in creating entrepreneurial outcomes. The absence of longitudinal analysis following students’ entrepreneurial careers beyond immediate graduation limits understanding of what types of EE work. Similarly, limitations in the form of EE - formal vs non-formal, focused vs blended - considered in much discussion prevents broader comparative understanding. This working paper sets out a framework and methodology for analysis to address some of these extant gaps. Positioning EE as part of an entrepreneurship centre (EC) model, delivering blended support across an institution via formal and non-formal means, it examines the progress and destination of students engaged with the EC and the blend of EE in which they participate during their studies. The proposed analysis will make three contributions toward EE debates; adding important longitudinal data to evidence on entrepreneurial outcomes, conducting a broader analysis of the effect of different modes of EE, and discussing the value and benefits of an EC model in delivering EE.

description: In the first part of the paper it is shown, that in the case of specific initial conditions, solutions of the Cauchy problem for linearized Boltzmann equation have exponential damping when time tends to infinity. In the second part of the paper exact analytic solution of spatially homogeneous linearized Boltzmann equation is built by the use of discrete Laplace transform. The result may be useful in research tasks inside the area of applied rarefied gas dynamics.

Sumset and inverse sumset theorems for Shannon entropy

description: Let $G = (G,+)$ be an additive group. The sumset theory of Plünnecke and Ruzsa gives several relations between the size of sumsets $A+B$ of finite sets $A, B$, and related objects such as iterated sumsets $kA$ and difference sets $A-B$, while the inverse sumset theory of Freiman, Ruzsa, and others characterises those finite sets $A$ for which $A+A$ is small. In this paper we establish analogous results in which the finite set $A \subset G$ is replaced by a discrete random variable $X$ taking values in $G$, and the cardinality $|A|$ is replaced by the Shannon entropy $\mathrm{Ent}(X)$. In particular, we classify the random variable $X$ which have small doubling in the sense that $\mathrm{Ent}(X_1+X_2) = \mathrm{Ent}(X)+O(1)$ when $X_1,X_2$ are independent copies of $X$, by showing that they factorise as $X = U+Z$ where $U$ is uniformly distributed on a coset progression of bounded rank, and $\mathrm{Ent}(Z) = O(1)$. When $G$ is torsion-free, we also establish the sharp lower bound $\mathrm{Ent}(X+X) \geq \mathrm{Ent}(X) + {1/2} \log 2 - o(1)$, where $o(1)$ goes to zero as $\mathrm{Ent}(X) \to \infty$.

description: In this article we exploit the Bhattacharyya statistical divergence to determine the similarity of probability distributions of quantum observables. After brief review of useful characteristics of the Bhattacharyya divergence we apply it to determine the similarity of probability distributions of two non-commuting observables. An explicit expression for the Bhattacharyya statistical divergence is found for the case of two observables which are the x- and z-components of the angular momentum of a spin-1/2 system. Finally, a note is given of application of the considered statistical divergence to the specific physical measurement.

Notes on SUSY and R-Symmetry Breaking in Wess-Zumino Models

description: We study aspects of Wess-Zumino models related to SUSY and R-symmetry breaking at tree-level. We present a recipe for constructing a wide class of tree-level SUSY and R-breaking models. We also deduce a general property shared by all tree-level SUSY breaking models that has broad application to model building. In particular, it explains why many models of direct gauge mediation have anomalously light gauginos (even if the R-symmetry is broken spontaneously by an order one amount). This suggests new approaches to dynamical SUSY breaking which can generate large enough gaugino masses.

Sustainable performance of bottled water firms in Ethiopia:
Creators: name: Jebel Ababulgu, Geda

Publisher: name: Visions for Sustainability
Year: 2024

description: Due to growing awareness of the negative environmental effects associated with the bottled water industry, there is increased pressure from customers, the government, and stakeholders for firms to adopt green supply chain management (GSCM) practices. These practices aim to minimize environmental consequences while enhancing social and economic performance. However, GSCM and sustainable development are still in their early stages of practice, particularly in Ethiopia where research investigations are limited. This study examines the impact of GSCM practices on environmental, economic, and social performance in the bottled water manufacturing industry in Ethiopia. A survey of 323 managers reveals that GSCM practices have a positive impact on all three dimensions of sustainability performance: environmental, social, and economic. However, the specific impact of each practice varies. All five GSCM practices improve the environmental performance of firms. Some practices also improve other dimensions of sustainability performance. For example, internal environmental management and cooperation with customers significantly improve social performance, but not economic performance. On the other hand, investment recovery improves economic performance. However, eco-design and green purchasing do not have a significant impact on economic or social performance. The findings of this study have theoretical implications and practical insights regarding sustainable performance for managers.

Contracting exceptional divisors by the Kähler-Ricci flow

description: We give a criterion under which a solution g(t) of the Kahler-Ricci flow contracts exceptional divisors on a compact manifold and can be uniquely continued on a new manifold. As t tends to the singular time T from each direction, we prove convergence of g(t) in the sense of Gromov-Hausdorff and smooth convergence away from the exceptional divisors. We call this behavior for the Kahler-Ricci flow a canonical surgical contraction. In particular, our results show that the Kahler-Ricci flow on a projective algebraic surface will perform a sequence of canonical surgical contractions until, in finite time, either the minimal model is obtained, or the volume of the manifold tends to zero.

Resonances and Twist in Volume-Preserving Mappings

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: The phase space of an integrable, volume-preserving map with one action and $d$ angles is foliated by a one-parameter family of $d$-dimensional invariant tori. Perturbations of such a system may lead to chaotic dynamics and transport. We show that near a rank-one, resonant torus these mappings can be reduced to volume-preserving "standard maps." These have twist only when the image of the frequency map crosses the resonance curve transversely. We show that these maps can be approximated---using averaging theory---by the usual area-preserving twist or nontwist standard maps. The twist condition appropriate for the volume-preserving setting is shown to be distinct from the nondegeneracy condition used in (volume-preserving) KAM theory.

description: dc magnetization and 31^P spin lattice relaxation rate in the polycrystalline sample of LaCoPO suggest a spin fluctuation dominated ferromagnetically ordered state. Moreover, NMR data clearly indicate a crossover from 2D to 3D spin fluctuations across T_C. In contrast to isotropic hyperfine field, H_hf at the 31^P site in LaFePO, H_hf is anisotropic in LaCoPO. The data of spin lattice relaxation rate also exhibit anisotropic spin fluctuation. The anisotropy vanishes near T_C.

Un recente studio pubblicato su The Astrophysical Journal dimostra che, col passare del tempo, le galassie massicce non aumentano di dimensioni come ritenuto in passato.

description: We study the free decay of capillary turbulence on the charged surface of liquid hydrogen. We find that decay begins from the high frequency end of the spectral range, while most of the energy remains localized at low frequencies. The apparent discrepancy with the self-similar theory of nonstationary wave turbulent processes is accounted for in terms of a quasi-adiabatic decay wherein fast nonlinear wave interactions redistribute energy between frequency scales in the presence of finite damping at all frequencies. Numerical calculations based on this idea agree well with experimental data.
