description: Large parts of the existing natural gas distribution networks must be decommissioned due to the decarbonization of the heat supply. However, there are neither regulatory nor economic incentives for the gas network operators to do so and delaying the decommissioning could be expensive for the remaining customers. This Weekly Report analyzes to what extent municipalities can partially decommission the natural gas infrastructure with the help of municipal heat planning and by re-municipalizing the gas industry. This study also outlines the challenges associated with these instruments. Accordingly, re-municipalization does not necessarily result in the gas networks being decommissioned faster, a fact that remains unconsidered in the existing heat plans. Furthermore, the current regulatory framework, which is based on cost efficiency and the obligation to connect, makes decommissioning more difficult. In addition, the municipalities have a financial incentive to continue generating revenue from gas, partially because alternative income sources for funding public services are unavailable. Thus, the regulation must be adjusted and the federal and state governments must provide more support for the municipalities in organizing the partial decommissioning of the natural gas infrastructure.

description: The gender care gap, i.e., the difference between the amount of unpaid care work—such as childcare and housework—performed between men and women is comparatively high in Germany: Women take on much more unpaid care work than men. This gap increases consistently when starting a family. At the beginning of the coronavirus pandemic in 2020, many feared that the gender care gap may grow even larger. In fact, empirical analyses show that gender differences in care work did increase in young families at the beginning of the pandemic, as primarily women took on the extra childcare work brought on by closures of daycare facilities and schools. However, using data from the family panel pairfam, this Weekly Report shows that the gender care gap has since returned to its—albeit still high—pre-pandemic level. If policymakers want to effectively combat gender inequalities on the labor market, they should focus more on the unequal division of care work and dismantle existing barriers preventing a more equal division. This could be done by, for example, increasing the period of parental leave earmarked to fathers, and reforming minijobs and Ehegattensplitting, i.e., the joint taxation of married couples with full income splitting.

description: Countries increasingly form alliances to collectively impose sanctions. However, the resulting impact of such coordination remains unclear. Analyzing the 2014 wave of sanctions against Russia over 400,000 simulations with a quantitative trade model, this report demonstrates that multilateral cooperation through coalitions simultaneously reduced domestic welfare losses incurred from sanctions and intensified welfare losses imposed on Russia. Results also reveal significant disparities within the coalition, with Russia sanctions placing relatively high economic costs on Baltic nations that can be mitigated through a burden-sharing program. Hypothetical cooperation by emerging economies like China is also shown to substantially raise the force of sanctions against Russia

description: In many European countries, men and women differ significantly in the amount of informal care work they provide for relatives, with women acting as caregivers far more frequently than men. This difference, known as the gender care gap, varies considerably between European countries, with Germany somewhere in the middle of the distribution. This Weekly Report analyzes the institutional, societal, and labor market factors that are related to the gender care gap across European countries. The results show that the gap is smaller in countries that spend more on the formal care system. In addition, they show that the gender care gap tends to be larger in countries that exhibit high gender inequality and high inequality in labor market participation between men and women. Thus, the results emphasize that the gender pay gap correlates with government investments in health care, the care system, and the labor market structure. To reduce the gender care gap, expenditure on formal care should be increased to relieve informal caregivers and improve the quality of care in professional facilities. At the same time, policymakers should use tax and family policy incentives to increase women’s workforce participation so that paid work and care work are more evenly distributed.

description: Patterns of human mobility and settlement are connected to the evolution of a society and the processes of urbanisation and industrialisation. Urbanization, rural-urban migration and settlement are important aspects in China's profound social change and economic reforms in recent decades. Due to its decades-long institutional constraints, the majority of rural-urban migrants prefer temporary migration or circular migration to permanent settlement if the household registration status is concerned. Research on China's internal migration to date have mainly focused on the role of institutional constraints on people's mobility and settlement. This thesis provides a new perspective in understanding migrants' settlement intentions and patterns, which is centred on migrants' settlement strategies in the context of economic transition and hukou reforms. The thesis examines how migrants intend to achieve permanent settlement by bypassing or overcoming hukou constraints. Based on the data from the 'Migrant Survey of Ningbo' conducted in 2014 and the 'Migrant Dynamics Monitoring Survey' conducted in 2013, this thesis found that the economic transition and hukou reforms provided migrants with opportunities to obtain full citizenship that is separated from their hukou status, which broadened the channels of achieving permanent settlement (Chapter 2). Particularly, the marketisation of the urban labour market improved migrants' socio-economic status and granted them with improved employment conditions, and therefore increasing the likelihood of their settling permanently and successfully via obtaining permanent residence, transferring their hukou status or owning local housing at the destination (Chapter 3). In addition, the urban housing market provided migrants with opportunities to achieve permanent settlement without having to transfer their hukou status. A new concept of 'de facto permanent settlement intention' was introduced to understand the diverse channels of permanent settlement based on the relaxed hukou constraints and the rise of urban housing market (Chapter 4). Further, regional differences in hukou premiums affected settlement intentions. Regions with high 'hukou premium' and quality social benefit entitlements were highly attractive to migrants, even though governments at all levels try to encourage migrants to permanently move to small- to -median cities (Chapter 5). The results of this study extend the application of migration theory in a society where profound social changes and rapid economic growth have been taking place in recent decades. The results provide a better understanding of migration and settlement decision making, which could inform policy formulation in the future.

Subjects: subject: Sovereign debt
subject: Sovereign debt crises and defaults
subject: haircuts

description: Many sovereign defaults have occurred worldwide over the past 200 years. An analysis of 321 sovereign debt restructurings since 1815 shows that foreign private and institutional investor losses were 43 percent on average. Notably, beginning in the 1970s, several debt exchanges have increasingly been required to resolve a default. To understand this new phenomenon better, this Weekly Report looks at total creditor losses across all restructurings during a default spell. Instead of focusing on each individual restructuring, the cumulative haircut adds up all losses across a default spell. These calculations show that debt crises with serial restructurings resulted in greater overall losses for creditors than a major one-off restructuring. The results conclude that it makes sense to perform a debt sustainability analysis independently and in a timely manner when determining the size of a haircut. This could lessen debt restructurings with shallow haircuts that do not manage to bring countries back to their sustainable debt path.

Our first contribution is an extension of $c_Γ(k,l)$ to signed graphs, for which we obtain an inclusion--exclusion formula and several special evaluations giving rise, e.g., to polynomials that encode balanced subgraphs. Our second goal is to derive combinatorial reciprocity theorems for $c_Γ(k,l)$ and its signed-graph analogues, reminiscent of Stanley's reciprocity theorem linking chromatic polynomials to acyclic orientations.

Generalized distance and applications in protein folding
Creators: name: Mohazab, Ali Reza
Publisher: name: University of British Columbia
Year: 2013

description: The Euclidean distance, D, between two points is generalized to the distance between strings or polymers. The problem is of great mathematical beauty and very rich in structure even for the simplest of cases. The necessary and sufficient conditions for finding minimal distance transformations are presented. Locally minimal solutions for one-link and two-link chains are discussed, and the large N limit of a polymer is studied. Applications of D to protein folding and structural alignment are explored, in particular for finding minimal folding pathways. Non-crossing constraints and the resulting untangling moves in folding pathways are discussed as well. It is observed that, compared to the total distance, these extra untangling moves constitute a small fraction of the total movement. The resulting extra distance from untangling movements (Dnx ) are used to distinguish different protein classes, e.g. knotted proteins from unknotted proteins. By studying the ensembles of untangling moves, dominant folding pathways are constructed for three proteins, in particular a knotted protein. Finally, applications of D, and related metrics to protein folding rate prediction are discussed. It is seen that distance metrics are good at predicting the folding rates of 3-state folders.
Thermal signatures of tether-cutting reconnections in pre-eruption coronal flux ropes: hot central voids in coronal cavities

Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Using a 3D MHD simulation, we model the quasi-static evolution and the onset of eruption of a coronal flux rope. The simulation begins with a twisted flux rope emerging at the lower boundary and pushing into a pre-existing coronal potential arcade field. At a chosen time the emergence is stopped with the lower boundary taken to be rigid. Then the coronal flux rope settles into a quasi-static rise phase during which an underlying, central sigmoid-shaped current layer forms along the so called hyperbolic flux tube (HFT), a generalization of the X-line configuration. Reconnections in the dissipating current layer effectively add twisted flux to the flux rope and thus allow it to rise quasi-statically, even though the magnetic energy is decreasing as the system relaxes. We examine the thermal features produced by the current layer formation and the associated "tether-cutting" reconnections as a result of heating and field aligned thermal conduction. It is found that a central hot, low-density channel containing reconnected, twisted flux threading under the flux rope axis forms on top of the central current layer. When viewed in the line of sight roughly aligned with the hot channel (which is roughly along the neutral line), the central current layer appears as a high-density vertical column with upward extensions as a "U" shaped dense shell enclosing a central hot, low-density void. Such thermal features have been observed within coronal prominence cavities. Our MHD simulation suggests that they are the signatures of the development of the HFT topology and the associated tether-cutting reconnections, and that the central void grows and rises with the reconnections, until the flux rope reaches the critical height for the onset of the torus instability and dynamic eruption ensues.

description: A search for pair-produced scalar particles decaying to a four-jet final state is presented. The analysis is performed using an integrated luminosity of 34 pb^-1 recorded by the ATLAS detector in 2010. No deviation from the Standard Model is observed. For a scalar mass of 100 GeV (190 GeV) the limit on the scalar gluon pair production cross section at 95% confidence level is 1 nb (0.28 nb). When these results are interpreted as mass limits, scalar-gluons (hyperpions) with masses of 100 to 185 GeV (100 to 155 GeV) are excluded at 95% confidence level with the exception of a mass window of width about 5 GeV (15 GeV) around 140 GeV.

description: The energy transition is a major challenge for both Germany and France. This Weekly Report provides an overview of the short- and long-term goals as well as current developments and trends in France’s energy and climate policy. It reveals that France is largely on track with its greenhouse gases targets and is also making good progress on installing heat pumps. However, its expansion of renewable energy capacities is falling short. Differences in the energy policies of France and Germany are most apparent in the power sector: While France is prioritizing nuclear power, Germany is relying heavily on renewable energy. For France to achieve its climate goals, it will have to expand renewable energy faster. One challenge faced by both countries is their planned electrification of mobility and space heating.

We prove that under diffusive rescaling of space-time, energy fluctuations diffuse and evolve following an infinite dimensional linear stochastic differential equation driven by the linearized heat equation. We also give variational expressions for the thermal diffusivity and some upper and lower bounds.

description: The recent up to 2fb^{-1} of data from the ATLAS and CMS experiments at the CERN Large Hadron Collider at 7TeV put an upper bound on the production cross section of a Higgs-like particle. We translate the results of the H -> WW -> l nu l nu and H -> gamma gamma as well as the combined analysis by the ATLAS and CMS into an allowed region for the Kaluza-Klein (KK) mass M_{KK} and the Higgs mass $M_H$ for all the known Universal Extra Dimension (UED) models in five and six dimensions. Our bound is insensitive to the detailed KK mass splitting and mixing and hence complementary to all other known signatures.

description: The number of women serving on the executive boards of large companies in Germany once again increased in 2023: Around 18 percent (153 of 875) of executive board members at the 200 largest companies were women as of late fall 2023, two percentage points higher than in 2022. Thus, growth has slightly picked up again. In some of the groups of companies analyzed, the figure was even higher. Around 23 percent of executive board members at the DAX 40 companies, for example, are women. The largest banks and insurance companies, which in the past years have lagged considerably behind other private sector companies and companies with government-owned shares, managed to catch up a bit. In many places, this growth is due to the fact that companies have appointed a woman to their executive board for the first time. Beyond that, there is currently not much progress. In addition, the number of women holding the position of CEO has decreased in many groups of companies. More commitment is needed from companies, both internally (e.g., from the supervisory board) and externally (e.g., from investors) to achieve gender parity in senior leadership positions.

description: Critical phenomena can show unusual phase diagrams when defined in complex network topologies. The case of classical phase transitions such as the classical Ising model and the percolation transition has been studied extensively in the last decade. Here we show that the phase diagram of the Bose-Hubbard model, an exclusively quantum mechanical phase transition, also changes significantly when defined on random scale-free networks. We present a mean-field calculation of the model in annealed networks and we show that when the second moment of the average degree diverges the Mott-insulator phase disappears in the thermodynamic limit. Moreover we study the model on quenched networks and we show that the Mott-insulator phase disappears in the thermodynamic limit as long as the maximal eigenvalue of the adjacency matrix diverges. Finally we study the phase diagram of the model on Apollonian scale-free networks that can be embedded in 2 dimensions showing the extension of the results also to this case.

description: Supersymmetric models with extended electroweak gauge groups have the potential to enhance the Higgs quartic interaction through nondecoupling D-terms. We consider the D-term enhancement effect in a vector top partner model, where the quadratic divergence to the Higgs mass from the virtual top quark is canceled by its corresponding spin-1 superpartners. We are going to show that the model can predict a Higgs mass beyond the LEP bound, and is consistent with the precision electroweak constraints.

Eterotopia, tecnica di straniamento: luoghi e figure del soggetto in Foucault e Lévi-strauss

Year: 2013
Subjects: Foucault; Lévi-Strauss; eterotopia; diversità culturale

description: Questa ricerca, attraverso alcune letture incrociate di Michel Foucault e di Claude Lévi-Strauss, mette in luce l’attualità di due grandi pensatori che pongono al centro delle loro teorie il tema della distanza, dell’altro da sé e del ritorno a sé per comprendere il ruolo del soggetto nella civiltà occidentale. Al di là delle rilevanti differenze che li contraddistinguono, Foucault e Lévi-Strauss percorrono due cammini teorici volti a decostruire il rapporto tra verità e soggetto nella civiltà occidentale adottando una prospettiva della distanza e dell’allontanamento da sé, quali tecniche per comprendere se stessi. Da una parte il concetto foucaultiano di eterotopia, in quanto «spazio assolutamente altro», permette di comprendere i meccanismi attraverso i quali ci si proietta in un altrove senza luogo preciso per localizzare se stessi. Il campo dell’etnologia, sarà dunque letto attraverso la lente foucaultiana, quale «eterotopologia», o scienza eterotopica, per eccellenza. Dall’altra, questo concetto sarà analizzato alla luce di quello che Lévi-Strauss ha definito nel saggio sui Tre umanesimi una «tecnica dello straniamento», ovvero un metodo che permette di pensare se stessi grazie al confronto con l’Altro, con culture di altri luoghi ed altri tempi: per conoscere il soggetto che è l’uomo, non si può non prescindere da un lavoro di continui raffronti e paragoni tra diverse società nel tempo e nello spazio.

description: High construction prices and worsened financing conditions are weighing on the construction industry, especially build-ing construction. Despite a nominal increase of six percent in construction expenses in 2023, it decreased by just over one percent in inflation-adjusted terms. In 2024, the nominal construction volume is likely to contract by around 3.5 percent, declining for the first time since the financial crisis due to falling construction prices. Residential construction in particular experienced a sharp decline in 2023 and will continue on this downward trend more strongly in 2024. Renovation and modernization activity is less affected than new construction. The situation will stabilize by 2025. The prospect of constructing 400,000 new residences annually is thus becoming increasingly out of reach. Only civil engineering is stabilizing the construction industry overall; it is likely to expand in both 2024 and 2025. The different growth prospects of the sectors require restructuring in the construction industry. In particular, capacities freed up in new residential construction should be utilized in the energy-efficient renovation of private and public buildings. Policy makers should actively support this restructuring. In addition, they should provide clarity about the subsidy programs for energy-efficient building renovation and residential unit construction. At the same time, it is important to maintain focus on the new housing construction target.

description: Most climate and energy scenarios created by international organizations and researchers include a considerable expansion of nuclear energy. In the IPCC Sixth Assessment Report, for example, nuclear energy increases from a current 3,000 terawatt hours on average to over 6,000 terawatt hours in 2050 and to over 12,000 terawatt hours in 2100. This doubling and quadrupling of nuclear energy production by 2050 and 2100 is contradictory to the technical and economic realities: At no point have newly built nuclear energy plants ever been competitive, nor will they become so in the foreseeable future. This contradiction, referred to here as the nuclear energy scenario paradox, can be explained by a series of politico- economic, institutional, and geopolitical factors. In particular, the close relationship between the military and commercial uses of nuclear energy as well as the interest of the nuclear industry and its organizations in self-preservation play a role. The assumptions and model logic of the scenarios must be critically scrutinized. There is the risk that considerable public and private funds will be invested in developing technologies for the commercial use of nuclear energy despite the fact that other technologies are expected to offer a significantly better cost-performance ratio with fewer economic, technical, and military risks. In light of the urgency of climate change mitigation, continuing to channel personnel and financial resources into nuclear energy is problematic.

description: It has been more than 30 years since 1983 when the floating exchange rate regime was introduced in Australia. The floating exchange rate is widely considered to bring benefits to the Australian economy through its role as a shock absorber. The present project investigates how the movement of the exchange rate affects Australian GDP and employment in the post-float era. The study’s results demonstrate that the impact from a one-standard-deviation unanticipated real exchange rate shock tends to cause more sectoral shifts on Australian GDP and employment growth rather than aggregate disturbances in the short run. We find that shock impacts are statistically insignificant on aggregate GDP growth and employment growth. At the industrial level, the extent of such shock impacts is largely based on the trade-exposure characteristics of industries. Finally, the results confirm that the floating exchange rate behaves as a shock absorber in the short run.

description: The unequal distribution of labor income in Germany is a hotly debated topic among policymakers and the general public alike. However, the relevant data for calculating the distribution is usually available with a delay of sometimes over two years. Accordingly, previous studies have only been about the past, not the current, distribution. Generally, the current development of the income distribution as well as the effects of current economic policy measures remain oblique. That is where DIW Berlin comes in: A new forecast model is making it possible to make statements about the current state of inequality in the monthly gross labor income of employees. To do so, a number of macroeconomic labor market variables, such as the share of people in short-time work as well as gross wages and salaries in various economic sectors, are combined with household-level data from the Socio-Economic Panel (SOEP). The calculations in this Weekly Report show that the forecast quality of the model is high. Thus, for the first time, insights into a longer period following the coronavirus pandemic can be gained: Following declining inequality up until 2021, primarily between 2010 and 2020, the new DIW Berlin model forecasts an interruption in the trend in 2022 and 2023. Overall, labor income inequality is predicted to have increased slightly over the course of the economic recovery following the pandemic and will be somewhat higher in 2023.

description: We investigate static properties of laser-driven, ultracold Rydberg atoms confined to one- and two-dimensional uniform lattices in the limit of vanishing laser coupling. The spectral structure of square lattices is compared to those of linear chains and similarities as well as differences are pointed out. Furthermore, we employ a method based on elements of graph theory to numerically determine the laser detuning-dependent ground states of various lattice geometries. Ground states for chains as well as square and rectangular lattices are provided and discussed.

subject: competition policy

description: The sharp rise in electricity prices has led to a discussion on possible subsidies for companies in the form of an industrial power tariff. The subsidies should help companies remain internationally competitive and prevent them from relocating overseas. Although German electricity prices for (industrial) firms are around the European average due to many tax exemptions, they are significantly higher compared to other non-European countries. Simulations using price increases of different magnitudes show that only a small share of companies would face major price increases compared to their value added. Moreover, there is considerable heterogeneity between the sectors. For example, the industrial gases or aluminum production sectors would be much more affected than other sectors. Thus, a large-scale industrial electricity price subsidy does not seem to be very effective. Selective relief for certain sectors may be problematic under competition law and may need to be granted well beyond the temporary nature of the subsidy.

Ultimate generalization of Noether's theorem in the realm of Hamiltonian point dynamics

description: Noether's theorem in the realm of point dynamics establishes the correlation of a constant of motion of a Hamilton-Lagrange system with a particular symmetry transformation that preserves the form of the action functional. Although usually derived in the Lagrangian formalism, the natural context for deriving Noether's theorem for first-order Lagrangian systems is the Hamiltonian formalism. The reason is that the class of transformations that leave the action functional invariant coincides with the class of canonical transformations. As a result, any invariant of a Hamiltonian system can be correlated with a symmetry transformation simply by means of the canonical transformation rules. As this holds for any invariant, we thereby obtain the most general representation of Noether's theorem. In order to allow for symmetry mappings that include a transformation of time, we must refer to the extended Hamiltonian formalism. This formalism enables us to define generating functions of canonical transformations that also map time and energy in addition to the conventional mappings of canonical space and momentum variables. As an example for the generalized Noether theorem, a manifest representation of the symmetry transformation is derived that corresponds to the Runge-Lenz invariant of the Kepler system.

description: Replacing fossil fuels with renewable energy sources is one cornerstone of the energy transition. In certain sectors, green hydrogen will play an important role in the future, as is envisioned in the revised National Hydrogen Strategy recently presented by the German Federal Government. This Weekly Report discusses important changes in this strategy compared to the first National Hydrogen Strategy from 2020. It focuses on the analysis of the hydrogen quantities planned for 2030, which can likely only be realized with significant effort. In addition, it is uncertain how large the remaining share of non-green hydrogen would be. Green hydrogen imports are of particular significance and must be secured early on. It is now important to implement the strategy in a timely and consistent fashion. In this context, focus should remain on the areas of application that are required from an energy system perspective and for which direct electrification, which is more energy efficient, is not possible, especially in industry as well as aviation and shipping.
