description: The bar formation is still an open problem in modern astrophysics. In this paper we present numerical simulation performed with the aim of analyzing the growth of the bar instability inside stellar-gaseous disks, where the star formation is triggered, and a central black hole is present. The aim of this paper is to point out the impact of such a central massive black hole on the growth of the bar. We use N-body-SPH simulations of the same isolated disk-to-halo mass systems harboring black holes with different initial masses and different energy feedback on the surrounding gas. We compare the results of these simulations with the one of the same disk without black hole in its center. We make the same comparison (disk with and without black hole) for a stellar disk in a fully cosmological scenario. A stellar bar, lasting 10 Gyrs, is present in all our simulations. The central black hole mass has in general a mild effect on the ellipticity of the bar but it is never able to destroy it. The black holes grow in different way according their initial mass and their feedback efficiency, the final values of the velocity dispersions and of the black hole masses are near to the phenomenological constraints.

description: The ALHAMBRA survey aims to cover 4 square degrees using a system of 20 contiguous, equal width, medium-band filters spanning the range 3500 A to 9700 A plus the standard JHKs filters. Here we analyze deep near-IR number counts of one of our fields (ALH08) for which we have a relatively large area (0.5 square degrees) and faint photometry (J=22.4, H=21.3 and K=20.0 at the 50% of recovery efficiency for point-like sources). We find that the logarithmic gradient of the galaxy counts undergoes a distinct change to a flatter slope in each band: from 0.44 at [17.0, 18.5] to 0.34 at [19.5, 22.0] for the J band; for the H band 0.46 at [15.5, 18.0] to 0.36 at [19.0, 21.0], and in Ks the change is from 0.53 in the range [15.0, 17.0] to 0.33 in the interval [18.0, 20.0]. These observations together with faint optical counts are used to constrain models that include density and luminosity evolution of the local type-dependent luminosity functions. Our models imply a decline in the space density of evolved early-type galaxies with increasing redshift, such that only 30% - 50% of the bulk of the present day red-ellipticals was already in place at z~1.

description: Data on the status of and changes in land use, i.e. on the use of soils and land areas by humans, represent a central basis for fact-based policy advice and research as well as various monitoring and evaluation tasks at the Thünen Institute. Accordingly, the Thünen Institute has broad expertise in the collection, management, processing and analysis of land use data for Germany. Against the background of current and future requirements as well as the dynamic development with regard to the type and quantity of data on land use, this working paper maps the status quo of the relevant work at the Thünen Institute and develops guidelines for an overall concept for land use data management. The focus is on the use of open land and forest areas in Germany. However, data in the land use area of settlement and transport are also considered. First, the needs and requirements that have developed for the processing of land use data at Thünen Institute in recent years are presented. This is followed in Chapter 2 by a description of the data held and processed at the Thünen Institute. Chapter 3 describes the available technical and human resources as well as the existing organisational structures. Chapter 4 describes the current tasks and the upcoming challenges. Finally, a perspective for further work with land use data at the Thünen Institute is described and outlined in a roadmap.

description: We present a new framework to detect various types of variable objects within massive astronomical time-series data. Assuming that the dominant population of objects is non-variable, we find outliers from this population by using a non-parametric Bayesian clustering algorithm based on an infinite GaussianMixtureModel (GMM) and the Dirichlet Process. The algorithm extracts information from a given dataset, which is described by six variability indices. The GMM uses those variability indices to recover clusters that are described by six-dimensional multivariate Gaussian distributions, allowing our approach to consider the sampling pattern of time-series data, systematic biases, the number of data points for each light curve, and photometric quality. Using the Northern Sky Variability Survey data, we test our approach and prove that the infinite GMM is useful at detecting variable objects, while providing statistical inference estimation that suppresses false detection. The proposed approach will be effective in the exploration of future surveys such as GAIA, Pan-Starrs, and LSST, which will produce massive time-series data.

description: We study a quasi-two-dimensional monolayer of granular rods fluidized by a spatially and temporally homogeneous upflow of air. By tracking the position and orientation of the particles, we characterize the dynamics of the system with sufficient resolution to observe ballistic motion at the shortest time scales. Particle anisotropy gives rise to dynamical anisotropy and superdiffusive dynamics parallel to the rod's long axis, causing the parallel and perpendicular mean squared displacements to become diffusive on different timescales. The distributions of free times and free paths between collisions deviate from exponential behavior, underscoring the non-thermal character of the particle motion. The dynamics show evidence of rotational-translational coupling similar to that of an anisotropic Brownian particle. We model rotational-translation coupling in the single-particle dynamics with a modified Langevin model using non-thermal noise sources. This suggests a phenomenological approach to thinking about collections of self-propelling particles in terms of enhanced memory effects.
An investigation into the relationship between moon phases and precipitation maximums in British Columbia
Creators: name: Emery, Frank Thomas
Publisher: name: University of British Columbia
Year: 2012

description: The correlations between moon phases and precipitation maximums were investigated for selected stations in British Columbia in order to determine if they existed for: (a) individual stations; (b) grouped stations; (c) annual occurrences; (d) seasonal occurrences; and (e) geographic areas. The analysis consisted of a graphical presentation and a statistical test for randomness. Graphs of annual and seasonal moving totals for grouped and Individual stations were prepared. They were analyzed for peaks in the configuration of the graphs and for annual and seasonal components through the use of the X2p test. It is apparent from this study that there is a relationship between moon phases and precipitation maximums for grouped stations and individual stations in British Columbia. The evidence for the annual components of "lunar" precipitation for the individual stations shows, statistically, that the distributions are non-random and, graphically, that peaks are visible. Moreover, a shift of the peaks with latitude is discernible for the stations of British Columbia and it is suggested that this shift exists on a global scale. The evidence for the seasonal components of "lunar" precipitation for the individual stations is not as conclusive, either statistically or graphically. The seasonal graphs show peaks but the test for randomness yields inconsistent results.
From Elastic Continua to Space-time

description: Since the early days of the theory of electromagnetism and of gravity the idea of space, then space-time, as a sort of physical continuum hovered the scientific community. Actually general relativity shows the strong similarity that exists between the geometrical properties of space-time and the ones of a strained elastic continuum. The bridge between geometry and the elastic potential, as well in three as in three plus one dimensions, is the strain tensor, read as the non-trivial part of the metric tensor. On the basis of this remark and exploiting appropriate multidimensional embeddings, it is possible to build a full theory of space-time, allowing to account for the accelerated expansion of the universe. How this can be obtained is the content of the paper. The theory fits the cosmic accelerated expansion data from type Ia supernovae better than the Lambda-CDM model.

description: Being the only energy sector where emissions are still at 1990 levels, the German transportation sector requires rapid decarbonization to achieve ambitious climate targets. Policy makers need to put the framework in place which enables and supports this transition. This work analyzes which policy areas should be targeted considering interactions with and implications for the entire energy system. The Global Energy System Model (GENeSYS-MOD) is used to compute 400 sensitivities which showcase the effectiveness of specific transport and energy system related policies. Shifting transportation demand to less energy and emission intensive modes or avoiding it in the first place shows the strongest effect on a number of key metrics. Primary energy consumption, emissions, and fleet size can all be reduced through a combination of electrification and shift towards public transport and long-distance trains. Carbon prices also showcase significant effects while further affecting the other energy sectors. The results suggest that in the intermediate term, modal shift and demand reduction can help with reducing transportation related emissions, while carbon prices are effective after 2040.

The work presented probes into the effects of the European emissions’ trading system on innovation, and the development of the Chinese wind power industry. Notable is also an analysis of people at Portuguese universities revealing lesser knowledge of renewable energy technologies but a more positive attitude towards this among women – and vice versa among men. EnergyPLAN-based energy systems analyses with cases from Iran and Serbia are presented, and different indicators for energy systems analyses are deliberated in a Mexican context. Marine energy developments in Columbia, the United Kingdom, Canada and Denmark are discussed with a focus on siting and barriers. Also, barriers against solar energy exploitation in Indonesia are explored as are barriers against energy savings in Nigeria.

Year: 2021

description: The offshore wind energy sector is showing a growing interest because the increment of global energy demand and the commitment to reduce the CO2 emissions. The need to identify new wind offshore areas have motivated the development of methods where several quantitative and qualitative factors are considered. Then, this study reviewed these factors to establish a priority order to know when they could be analyzed within 3 main stages (pre-feasibility, feasibility and final decision). As a result, this research organized tha main factors in the 3 stages and performed a pre-feasibility analysis for assessing potential offshore areas considering technical-environmental features such as spatial classification, temporal variability (magnitude and direction) and geographical restrictions. The Colombian Caribbean coast was selected as study case, and 3 areas were identified according to their wind climate variability, in which 10 locations showed high potential for developing offshore wind projects. The north and central zone of the Colombian Caribbean coast were identified as the most suitable areas with mean annual wind-speed over 10 m/s with low magnitude and direction variability, two factors considered extremely important for the wind power generation.

description: Despite high expectations for the sector, most marine energy technologies remain in the research and development, or at best demonstration, phase. The industry is in a period of stagnation, and requires new approaches to overcome the challenges that inhibit widespread deployment. Small-scale initiatives have proven to be a successful means of developing other renewable technologies but their role in supporting marine energy is not well researched. This paper provides a review of the barriers and opportunities presented by different policy landscapes, financial support mechanisms, markets, key actors, and wider regulatory and governance issues. Semi-structured interviews with marine energy stakeholders from the UK, Canada and Denmark were used to explore the role of small-scale marine energy projects, and were supplemented by interviews with the general public in England. This showed that while marine energy is appropriately scalable for local projects, financing remains a major hurdle. Discretionary local authority finance, as well as other novel options such as crowdfunding, tends to be relatively modest, supporting the argument for small-scale projects. A market for smaller devices exists, particularly for remote communities currently dependent on expensive energy from oil-fired generators. There remains a significant role for small-scale projects in testing the technology, contributing to reductions in cost and environmental risk. Current processes for environmental impact assessment can present a significant hurdle for small projects, but proportionate, adaptive assessments are evolving. Finally, community ownership and public participation have the potential to increase advocacy for the industry, with multi-actor partnerships presenting a positive way forward.

The consequences of this dependence are studied in more detail for the case of nonlinear magneto-optical rotation in the Faraday geometry (an effect requiring the creation and detection of rank-two polarization in the ground state) with alkali atoms. Analytic formulas for the optical rotation signal under various experimental conditions are presented.

description: When an open system of classical point particles interacting by Newtonian gravity collapses and relaxes violently, an arbitrary amount of energy may in principle be carried away by particles which escape to infinity. We investigate here, using numerical simulations, how this released energy and other related quantities (notably the binding energy and size of the virialized structure) depends on the initial conditions, for the one parameter family of starting configurations given by randomly distributing N cold particles in a spherical volume. Previous studies have established that the minimal size reached by the system scales approximately as N^{-1/3}, a behaviour which follows trivially when the growth of perturbations (which regularize the singularity of the cold collapse in the infinite N limit) are assumed to be unaffected by the boundaries. Our study shows that the energy ejected grows approximately in proportion to N^{1/3}, while the fraction of the initial mass ejected grows only very slowly with N, approximately logarithmically, in the range of N simulated. We examine in detail the mechanism of this mass and energy ejection, showing explicitly that it arises from the interplay of the growth of perturbations with the finite size of the system. A net lag of particles compared to their uniform spherical collapse trajectories develops first at the boundaries and then propagates into the volume during the collapse. Particles in the outer shells are then ejected as they scatter through the time dependent potential of an already re-expanding central core. Using modified initial configurations we explore the importance of fluctuations at different scales, and discreteness (i.e. non-Vlasov) effects in the dynamics.

description: Abstract Global energy demand is increased due to industrial development. Currently, fossil fuels, with more than 85%, are the most prominent source of energy in Iran, and their consumption has been raised, but it has destructive impacts on the environment and human health. This study aims to model and techno-economically assess renewable energy heating for replacing natural gas in Qazvin city. The natural gas domestic demand was quantified, followed by consumption forecasting for 15 years. Six different scenarios were investigated to assess renewables’ potential to meet the city heat demand for the next 15years. The study uncovers that the best practice scenario can reduce natural gas consumption and increase renewable energies share. Finally, the proposed scenario was analyzed economically and environmentally. Results revealed that the return on investment would occur in 3 years by exporting the saved natural gas. Also, Iran can reduce CO2 emissions by about 1 million tons by the year 2029.

description: We present an analytical model for jets in Fanaroff & Riley Class I (FRI) radio galaxies, in which an initially laminar, relativistic flow is surrounded by a shear layer. We apply the appropriate conservation laws to constrain the jet parameters, starting the model where the radio emission is observed to brighten abruptly. We assume that the laminar flow fills the jet there and that pressure balance with the surroundings is maintained from that point outwards. Entrainment continuously injects new material into the jet and forms a shear layer, which contains material from both the environment and the laminar core. The shear layer expands rapidly with distance until finally the core disappears, and all of the material is mixed into the shear layer. Beyond this point, the shear layer expands in a cone and decelerates smoothly. We apply our model to the well-observed FRI source 3C31 and show that there is a self-consistent solution. We derive the jet power, together with the variations of mass flux and and entrainment rate with distance from the nucleus. The predicted variation of bulk velocity with distance in the outer parts of the jets is in good agreement with model fits to VLA observations. Our prediction for the shape of the laminar core can be tested with higher-resolution imaging.

description: Countries with emerging economies face a significant challenge when developing strategies to move towards a low emission energy system and keep their economies growing. The power System plays a crucial role in these strategies and by the correct measurement of its sustainability is possible to identify which alternative improves sustainability the most. This article proposes indicators for the evaluation and assessment of the sustainability of Mexican Power System planning scenarios put forward by two government administrations with a study horizon to 2030. The scenarios are characterized by the program of additions and retirements of generating capacity along the period of 2019 to 2030, and eventually, optimal dispatch was obtained to accomplish the hourly demand. Sustainability indicators were developed and calculated to evaluate the energy security, energy equity and environmental sustainability dimensions. Subsequently the indicators were fed to the Position Vector of Minimum Regret Analysis as multicriteria decision analysis. By analysing the results, it is highlighted that the expansion of power grid capacity, as well as the hourly availability of hydro plants improve the sustainability of the Mexican Power System. The comparison between both scenarios’ performance, based on the Energy Trilemma, indicates that the current government’s planning is slightly more sustainable.

Massive gravitational waves from the Cosmic Defect theory

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The Cosmic Defect theory (CD), which is presented elsewhere in this conference, introduces in the standard Einstein-Hilbert Lagrangian an elastic term accounting for the strain of space-time viewed as a four-dimensional physical continuum. In this framework the Ricci scalar acts as the kinetical term of the strain field whose potential is represented by the additional terms. Here we are presenting the linearised version of the theory in order to analyze its implications in the weak field limit. First we discuss the recovery of the Newtonian limit. We find that the typical static weak field limit imposes a constraint on the values of the two parameters (Lame coefficients) of the theory. Once the constraint has been implemented, the typical gravitational potential turns out to be Yukawa-like. The value for the Yukawa parameter is consistent with the constraints coming from the experimental data at the Solar system and galactic scales. We then come to the propagating solutions of the linearised Einstein equations in vacuo, i.e. to gravitational waves. Here, analogously with other alternative or extended theories of gravity, the presence of the strain field produces massive waves, where massive (in this completely classical context) means subluminal. Furthermore longitudinal polarization modes are allowed too, thus lending, in principle, a way for discriminating these waves from the plane GR ones.

description: This article aims to assess the impact of a specific regulation, namely the European Union emission trading system (EU-ETS), on the Eco-Innovation (EI) activities of the companies, to assess its effectiveness in changing the companies’ environmental behavior. It also intendsto empirically examine whether the EU-ETS and its ‘stringency’ are significantly related to EI, taking into account both the internal and external factors that might be correlated with EI. To this end, we develop a cross-sectional framework using the Community Innovation Survey (CIS) data and by creating a stringency indicator for the period between 2012-2014 for 13 European countries. We found that the EU-ETS has limited and some controversial effects. Furthermore, technology policies emerge as an important element of the policy mix complementing climate policy. Based on our findings, we make recommendations for policymakers on how to improve the existing policy mix.

Evaluation of China’s policy for wind power development from the new structural economics perspective
Creators: name: Brusiło, Paweł
Publisher: name: International Journal of Sustainable Energy Planning and Management
Year: 2021

description: The Chinese energy transition, as a shift from fossil fuels to renewable energy sources, involves the dynamic growth of wind power’s importance in a national energy mix. The development of the wind power industry in this country is intertwined with the implemented policies that translated to the significant increase in energy generation from this power source and the growth of trade volumes of wind power products. This research aims to review and analyse the China's policy that impacted wind power development in 2000-2019. The author aims to evaluate the efficiency of implemented policies and strategies from the perspective of the new structural economics assumptions and the revealed comparative advantage of the Chinese wind energy products. In addition to the review of scientific literature and policy documents, as well as analysis of the relevant trade and energy indicators, the method applied in this research is a calculation of the Revealed Comparative Advantage (RCA) index. The results provide pieces of evidence that despite the substantial development of the Chinese wind power industry on a national scale, this country still has not revealed a comparative advantage globally. However, the results also suggest that the Chinese wind power industry is on the right track to achieve export specialisation soon. Furthermore, the China's policy for wind power development matches the new structural economics assumptions. The presented insight into studied industry blazes the trail for other countries, which consider following the Chinese development path by shaping the growth of leading-edge industries and the energy transition process throughout various state interventions.

Magnons, their Solitonic Avatars and the Pohlmeyer Reduction

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the solitons of the symmetric space sine-Gordon theories that arise once the Pohlmeyer reduction has been imposed on a sigma model with the symmetric space as target. Under this map the solitons arise as giant magnons that are relevant to string theory in the context of the AdS/CFT correspondence. In particular, we consider the cases S^n, CP^n and SU(n) in some detail. We clarify the construction of the charges carried by the solitons and also address the possible Lagrangian formulations of the symmetric space sine-Gordon theories. We show that the dressing, or Backlund, transformation naturally produces solitons directly in both the sigma model and the symmetric space sine-Gordon equations without the need to explicitly map from one to the other. In particular, we obtain a new magnon solution in CP^3. We show that the dressing method does not produce the more general "dyonic" solutions which involve non-trivial motion of the collective coordinates carried by the solitons.

template for promoting energy conservation in Nigeria’s residential sector

description: Energy conservation is an all-encompassing principle (building economics, behavioural, technological and educational) whose cumulative effects can result to improvement in energy access, energy availability and sufficiency, quality of life and retractive impacts on climate change and reduction in carbon footprint of a country. With the current global realities of COVID-19 pandemic, energy conservation has become one of the systemic resilience strategies necessary to manage dwindling energy supplies and financial shocks. However, as simplistic as it sounds, energy conservation as a behaviour of household consumers is a complex phenomenon that has persisted throughout the century. While strategic policies and long-term planning have promoted and re-orient consumers in some developed and developing countries towards energy conservation behaviour, there is no paradigm shift from energy wastage to energy conservation among consumers in Nigeria’s residential sector. This paper therefore discusses the factors that constrains energy conservation among household electricity consumers, unearths precursors and enablers of energy conservation with peculiar appeal to Nigeria. Policy implications and strategies of entrenching energy conservation culture are also outlined.

description: We report on a successful, simultaneous observation and modeling of the sub-millimeter to near-infrared flare emission of the Sgr A* counterpart associated with the super-massive black hole at the Galactic center. Our modeling is based on simultaneous observations that have been carried out on 03 June, 2008 using the NACO adaptive optics (AO) instrument at the ESO VLT and the LABOCA bolometer at the APEX telescope. Inspection and modeling of the light curves show that the sub-mm follows the NIR emission with a delay of 1.5+/-0.5 hours. We explain the flare emission delay by an adiabatic expansion of the source components.

Women vs Men: Who performs better on Energy Literacy?
Creators: name: Martins, Ana
Publisher: name: International Journal of Sustainable Energy Planning and Management

description: Energy literacy is seen as one of the most powerful tools, available to ordinary people, to contribute to a more sustainable world. Since women tend to be considered the main caregivers, due to their maternal instinct, being generally more attentive, more altruistic, and more concerned with the future of their children, are women more involved in the transition to a more sustainable future? To answer this question, we seek to assess the literacy levels of Portuguese university members and explore the differences between men and women. Using the Heteroskedastic Ordered Probit, we found that women tend to have lower levels of knowledge about energy, but a more positive and sustainable attitude and behavior.

description: Inflationary cosmology is successful in explaining a number of outstanding cosmological issues including the flatness, the horizon and the relic issues. More spectacular is the experimental confirmation of the structure as arose from the inflationary quantum fluctuations. However, the physics in the inflationary era is unclear. Polarization observations of Cosmic Microwave Background (CMB) missions may detect the tensor mode effects of inflationary gravitational waves (GWs) and give an energy scale of inflation. To probe the inflationary physics, direct observation of gravitational waves generated in the inflationary era is needed. In this essay, we advocate that the direct observation of these GWs with sensitivity Omega-gw down to 10**(-23) is possible using present projected technology development if foreground could be separated.

The discontinuous nature of chromospheric activity evolution

description: Chromospheric activity has been thought to decay smoothly with time and, hence, to be a viable age indicator. Measurements in solar type stars in open clusters seem to point to a different conclusion: chromospheric activity undergoes a fast transition from Hyades level to that of the Sun after about 1 Gyr of main--sequence lifetime and any decaying trend before or after this transition must be much less significant than the short term variations.
