description: In this work we combine two distinct machine learning methodologies, sequential Monte Carlo and Bayesian experimental design, and apply them to the problem of inferring the dynamical parameters of a quantum system. We design the algorithm with practicality in mind by including parameters that control trade-offs between the requirements on computational and experimental resources. The algorithm can be implemented online (during experimental data collection), avoiding the need for storage and post-processing. Most importantly, our algorithm is capable of learning Hamiltonian parameters even when the parameters change from experiment-to-experiment, and also when additional noise processes are present and unknown. The algorithm also numerically estimates the Cramer-Rao lower bound, certifying its own performance.

description: It is often assumed that few- and many-body systems can be accurately described by considering only pairwise two-body interactions of the constituents. We illustrate that three- and higher-body forces enter naturally in effective field theories and are especially prominent in strongly interacting quantum systems. We focus on three-body forces and discuss examples from atomic and nuclear physics. In particular, we highlight the importance and the challenges of three-nucleon forces for nuclear structure and reactions, including applications to astrophysics and fundamental symmetries.

description: We present a catalog of 1964 isolated, compact neutral hydrogen clouds from the Galactic Arecibo L-Band Feed Array Survey Data Release One (GALFA-HI DR1). The clouds were identified by a custom machine-vision algorithm utilizing Difference of Gaussian kernels to search for clouds smaller than 20'. The clouds have velocities typically between |VLSR| = 20-400 km/s, linewidths of 2.5-35 km/s, and column densities ranging from 1 - 35 x 10^18 cm^-2. The distances to the clouds in this catalog may cover several orders of magnitude, so the masses may range from less than a Solar mass for clouds within the Galactic disc, to greater than 10^4 Solar Masses for HVCs at the tip of the Magellanic Stream. To search for trends, we separate the catalog into five populations based on position, velocity, and linewidth: high velocity clouds (HVCs); galaxy candidates; cold low velocity clouds (LVCs); warm, low positive-velocity clouds in the third Galactic Quadrant; and the remaining warm LVCs. The observed HVCs are found to be associated with previously-identified HVC complexes. We do not observe a large population of isolated clouds at high velocities as some models predict. We see evidence for distinct histories at low velocities in detecting populations of clouds corotating with the Galactic disc and a set of clouds that is not corotating.

Non-barotropic linear Rossby wave instability in three-dimensional disks

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Astrophysical disks with localized radial structure, such as protoplanetary disks containing dead zones or gaps due to disk-planet interaction, may be subject to the non-axisymmetric Rossby wave instability (RWI) that lead to vortex-formation. The linear instability has recently been demonstrated in three-dimensional (3D) barotropic disks. It is the purpose of this study to generalize the 3D linear problem to include an energy equation, thereby accounting for baroclinity in three-dimensions. Linear stability calculations are presented for radially structured, vertically stratified, geometrically-thin disks with non-uniform entropy distribution in both directions. Polytropic equilibria are considered but adiabatic perturbations assumed. The unperturbed disk has a localized radial density bump making it susceptible to the RWI. The linearized fluid equations are solved numerically as a partial differential equation eigenvalue problem. Emphasis on the ease of method implementation is given. It is found that when the polytropic index is fixed and adiabatic index increased, non-uniform entropy has negligible effect on the RWI growth rate, but pressure and density perturbation magnitudes near a pressure enhancement increases away from the midplane. The associated meridional flow is also qualitatively changed from homentropic calculations. Meridional vortical motion is identified in the nonhomentropic linear solution, as well as in a nonlinear global hydrodynamic simulation of the RWI in an initially isothermal disk evolved adiabatically. Numerical results suggest buoyancy forces play an important role in the internal flow of Rossby vortices.

description: Utilizing the integral expression of Coulomb's Law to determine the electric potential from a continuous charge distribution is a canonical exercise in Electricity and Magnetism (E&M). In this study, we use both think-aloud interviews and responses to traditional exam questions to investigate student difficulties with this topic at the upper-division level. Leveraging a theoretical framework for the use of mathematics in physics, we discuss how students activate, construct, execute and reflect on the integral form of Coulomb's Law when solving problems with continuous charge distributions. We present evidence that junior-level E&M students have difficulty mapping physical systems onto the mathematical expression for the Coulomb potential. Common challenges include difficulty expressing the difference vector in appropriate coordinates as well as determining expressions for the differential charge element and limits of integration for a specific charge distribution. We discuss possible implications of these findings for future research directions and instructional strategies.

description: We study the stability of solution branches for the Lichnerowicz-York equation at moment of time symmetry with constant unscaled energy density. We prove that the weak-field lower branch of solutions is stable whilst the upper branch of strong-field solutions is unstable. The existence of unstable solutions is interesting since a theorem by Sattinger proves that the sub-super solution monotone iteration method only gives stable solutions.

The influence of orbital dynamics, shape and tides on the obliquity of Mercury

description: Earth-based radar observations of the rotational dynamics of Mercury (Margot et al. 2012) combined with the determination of its gravity field by MESSENGER (Smith et al. 2012) give clues on the internal structure of Mercury, in particular its polar moment of inertia C, deduced from the obliquity (2.04 +/- 0.08) arcmin. The dynamics of the obliquity of Mercury is a very-long term motion (a few hundreds of kyrs), based on the regressional motion of Mercury's orbital ascending node. This paper, following the study of Noyelles & D'Hoedt (2012), aims at first giving initial conditions at any time and for any values of the internal structure parameters for numerical simulations, and at using them to estimate the influence of usually neglected parameters on the obliquity, like J3, the Love number k2 and the secular variations of the orbital elements. We use for that averaged representations of the orbital and rotational motions of Mercury, suitable for long-term studies. We find that J3 should alter the obliquity by 250 milli-arcsec, the tides by 100 milli-arcsec, and the secular variations of the orbital elements by 10 milli-arcsec over 20 years. The resulting value of C could be at the most changed from 0.346mR^2 to 0.345mR^2.

description: We study higher dimensional models with magnetic fluxes, which can be derived from superstring theory. We study mass spectrum and wavefunctions of massless and massive modes for spinor, scalar and vector fields. We compute the 3-point couplings and higher order couplings among massless modes and massive modes in 4D low-energy effective field theory. These couplings have non-trivial behaviors, because wavefunctions of massless and massive modes are non-trivial.

description: Die Neubautätigkeit von Einfamilienhäusern liegt in Deutschland seit rund 10 Jahren konstant bei ca. 85.000 Fertigstellungen pro Jahr. Informationen wie viel davon in Innenentwicklung realisiert werden, liegen bislang nicht vor; es muss aber davon ausgegangen werden, dass ein wesentlicher Teil als Außenentwicklung auf Freiflächen und landwirtschaftlich genutzten Flächen stattfindet und damit unvermindert zur Flächenneuinanspruchnahme beiträgt. Während in den dynamisch wachsenden Großstadtregionen hohe Preise zunehmend die Realisierung von Geschosswohnungsbau auch im Stadtumland und damit eine effiziente Flächennutzung begünstigen, ist in den ländlicheren Gebieten mit weniger angespannten Boden- und Wohnungsmärkten nach wie vor eine hohe Flächeninanspruchnahme zu beobachten. Im vorliegenden Beitrag werden Ergebnisse des Forschungsprojekts „Trends und Tendenzen der Siedlungsentwicklung und deren Auswirkungen auf das Erreichen der flächenpolitischen Ziele des Bundes“ vorgestellt, in dem die Wohnbauflächenentwicklung im Rahmen eines Fallstudien-Ansatzes quantitativ und qualitativ analysiert wurde. Als regionale Fallstudien werden die Stadt-Land-Regionen Deggendorf, Minden/Nienburg, Wolfsburg, Magdeburg und Dresden untersucht. Einfamilienhausgebiete werden mithilfe eines Ansatzes zur Siedlungsstrukturanalyse, der eine Klassifizierung des Gebäudetyps erlaubt, in Kombination mit topographischen Daten zu mehreren Zeitständen, identifiziert. Als zentrales Ergebnis werden eine kleinräumige Auswertung der von 2006-2019 außerhalb des bestehenden Siedlungszusammenhangs neu hinzugekommenen Flächen für Wohnnutzung und eine Charakterisierung der Neubaugebiete hinsichtlich durchschnittlicher Größe, Dichte und räumlicher Verteilung vorgestellt. Mithilfe von Interviews in den Fallregionen werden Handlungsmuster der angebots- und nachfrageseitigen Akteure identifiziert, die zur Entwicklung von Einfamilienhausgebieten beitragen. Der Vortrag fokussiert auf die empirischen Ergebnisse des Projekts. Im ebenfalls am DFNS stattfindenden Workshop „Flächenneuinanspruchnahme durch Einfamilienhausgebiete – Akteure und Handlungs­muster verstehen, Flächen sparen“, werden darauf aufbauend Handlungsempfehlungen und Instrumente diskutieren, die dazu beitragen die Siedlungsentwicklung in Räumen mit entspannten Wohnungsmärkten flächensparender zu gestalten und ein Umdenken hin zur Bestands- und Innenentwicklung zu unterstützen.

description: We clarify questions related to the convergence of the OPE and conformal block decomposition in unitary Conformal Field Theories (for any number of spacetime dimensions). In particular, we explain why these expansions are convergent in a finite region. We also show that the convergence is exponentially fast, in the sense that the operators of dimension above Delta contribute to correlation functions at most exp(-a Delta). Here the constant a>0 depends on the positions of operator insertions and we compute it explicitly.

description: The COVID-19 pandemic has prompted governments across the world to take unprecedented responses in an attempt to contain the spread of the new coronavirus – colloquially known as lockdowns. Adopting a contextually situated approach on the lockdown measures and powers in a cross-country analysis of Turkey, the United Kingdom and Germany, this paper pursues two arguments: First, it finds that the expansion of executive power during the COVID-19 pandemic is a common problem across different regime types and constitutional settlements. Based on this finding, the paper then contends that the expansion of executive power is informed and shaped by endogenous dynamics. Even when the executive branch does not appear motivated to pursue the augmentation of executive power in the beginning, a number of mutually reinforcing processes and dynamics may lead to rule them assertively, to assume more prerogative powers and to further undermine the accountability mechanisms. Such processes and dynamics include: (1) the nature of the threat and the technocratic manifestations of the COVID-19 emergency which both required unprecedented responses and affected different branches of government differently; (2) the ‘rally-around-the-flag’ high public support towards governments and political leaders which provided incentives to take even far-reaching pandemic measures, and (3) the failing authority of the World Health Organization in managing and coordinating the global risks posed by the COVID-19 pandemic which stoked nationalist pandemic responses. The findings of the paper suggest that the conventional (constitutional) theory in health emergencies underwent a reinvention to the detriment of institutional checks and balances, parliamentary supervision and judicial independence during the COVID-19 pandemic. Considering the endogeneity of the crisis, and the fact that an era of emergencies is set to bear down on us, there is alarming signals that executive over-reach will become more prevalent in future health emergencies.

description: Future large water Cherenkov and scintillator detectors have been proposed for measurements of long baseline neutrino oscillations, proton decay, supernova and solar neutrinos. To ensure cost-effectiveness and optimize scientific reach, one of the critical requirements for such detectors are large-area, high performance photomultiplier tubes (PMTs). One candidate for such a device is the Hamamatsu R11780, a 12" PMT that is available in both standard and high quantum efficiency versions. Measurements of the single photoelectron response characteristics, relative efficiencies of the standard and high quantum efficiency versions, a preliminary measurement of the absolute quantum efficiency of the standard quantum efficiency version, and a two-dimensional scan of the relative efficiency across the photocathode surface are presented in this paper. All single photoelectron investigations were made using a Cherenkov light source at room temperature at a gain of 1*10^7. These results show that the R11780 PMT is a excellent candidate for such large optical detectors, including the peak-to-valley ratios greater than 2, transit time spreads around 1.3 ns, and late-pulsing probabilities less than 5%.

description: Recently, the ATLAS and CMS detectors have discovered a bosonic particle which, to a reasonable degree of statistical uncertainty, fits the profile of the Standard Model Higgs. One obvious implication is that models which predict a significant departure from Standard Model phenomenology, such as large exotic (e.g., invisible) Higgs decay or mixing with a hidden sector scalar, are already ruled out. This observation threatens the viability of electroweak baryogenesis, which favors, for example, a lighter Higgs and a Higgs coupled to or mixed with light scalars. To assess the broad impact of these constraints, we propose a scheme for classifying models of the electroweak phase transition and impose constraints on a class-by-class basis. We find that models, such as the MSSM, which rely on thermal loop effects are severely constrained by the measurement of a 125 GeV Higgs. Models which rely on tree-level effects from a light singlet are also restricted by invisible decay and mixing constraints. Moreover, we find that the parametric region favored by electroweak baryogenesis often coincides with an enhanced symmetry point with a distinctive phenomenological character. In particular, enhancements arising through an approximate continuous symmetry are phenomenologically disfavored, in contrast with enhancements from discrete symmetries. We also comment on the excess of diphoton events observed by ATLAS and CMS. We note that although Higgs portal models can accommodate both enhanced diphoton decay and a strongly first order electroweak phase transition, the former favors a negative Higgs portal coupling whereas the latter favors a positive one, and therefore these two constraints are at tension with one another.

Flächenbedarfe der Politik der Bundesregierung und Umgang mit Flächennutzungskonkurrenzen
Creators: name: Burchardi, Jan-Erik
Publisher: name: Zenodo
Year: 2023
Subjects: DFNS 2023

description: Der Koalitionsvertrag enthält zahlreiche Zielvorgaben, deren Umsetzung die Nutzung von Flächen voraussetzt. Der vorgesehene Ausbau der Erneuerbaren Energien braucht Flächen für Windkraft, Agri-Photovoltaik und Freiflächenphotovoltaik, aber auch für den dazugehörigen Ausbau der erforderlichen Infrastrukturen. Das Bündnis bezahlbarer Wohnraum erarbeitet Vorschläge für Maßnahmen, mit denen das Ziel, 400.000 neue Wohnungen pro Jahr zu bauen, umgesetzt werden kann. Der Ausbau der Verkehrsinfrastruktur bedarf Flächen für Straßen- und Schienenprojekte. Wälder sollen erneuert werden und die Biodiversität soll mehr Schutzflächen bekommen. Und nicht zuletzt haben der russische Angriffskrieg gegen die Ukraine und dessen Auswirkungen auf die Versorgungslage mit bestimmten Lebensmitteln, wie Weizen und Sonnenblumenöl, deutlich gemacht, dass wir – auch in Deutschland – ausreichend Flächen für die Lebensmittelversorgung benötigen. Neben diesen neuen Ausbauzielen hat die Bundesregierung das Ziel aus der deutschen Nachhaltigkeitsstrategie, die Flächenneuinanspruchnahme bis 2030 auf 30 ha/Tag zu senken, im Koalitionsvertrag erneut bekräftigt. Während finanzwirksame neue Maßnahmen jedoch oftmals unter dem Vorbehalt der verfügbaren Haushaltsmittel stehen, fehlt im Bereich der Flächennutzung ein entsprechend wirkender politischer „Vorbehalt der verfügbaren Flächen“. Stattdessen werden die neuen Maßnahmen per Gesetz als prioritär und im Interesse der öffentlichen Sicherheit in der Abwägungshierarchie hochgestuft. Der Vortrag analysiert im ersten Teil, wie sich die von der Bundesregierung geplanten Maßnahmen auf die Flächennutzung in Deutschland auswirken könnten und ob sich trotzdem das 30 ha/Tag-Ziel erreichen lässt. Dabei wird es auch um bestehende Erkenntnislücken hinsichtlich der Flächenabschätzung, beispielsweise im Bereich der Ausgleichs- und Kompensationsflächen, gehen. Im zweiten Teil geht der Vortrag der Frage nach, ob und mit welchen Hebeln Flächennutzungskonkurrenzen entschärft und das 30 ha/Tag-Ziel eingehalten werden könnte. Dabei soll insbesondere untersucht werden, welche Nutzungen sinnvoll kombiniert und damit ohne zusätzlichen Flächenbedarf umgesetzt werden können. Abschließend sollen außerdem Überlegungen zu einem neuen planungs- und genehmigungsrechtlichen Grundsatz der „Mehrfachnutzung vor Einfachnutzung“ vorgestellt werden.
Sustainable Dairy Farming: Evaluating the Economic Impacts of Greenhouse Gas Mitigation Strategies Using Simulation Models

description: The dairy industry's commitment to achieving net zero greenhouse gas (GHG) emissions by 2050 has placed significant pressure on dairy farms, as emissions from field-to-farm gate account for the majority (78%–83%) of total emissions. This research employed the Integrated Farm System Management (IFSM) software modeling tool using Life Cycle Analysis (LCA) methodology to analyze field-to-farm gate emissions associated with various mitigation options across five heterogeneous dairy farms. A total of 70 economic models were estimated with the goal of informing stakeholders and policymakers on maintaining dairy farm economic viability while reducing GHG emissions. The IFSM modeling indicates that dairy farms have multiple mitigation options available, with the most significant reduction in GHG emissions achieved through adding pasture grazing and changing feed requirements with carbon footprint reductions from 2.7% to 26.7%. When employed alongside anaerobic digestion (AD) systems, these mitigation options resulted in a reduction in emissions ranging from 16.0% to 37.3%, albeit with a corresponding decrease in return to management (RTM) of 0.4% to 14.8%. In contrast, the most profitable approaches without utilizing AD systems, such as the use of larger Holsteins for increased milk production or increased cropland utilization, were found to yield higher profits ranging from 1.3% to 19.5% but showed a limited reduction in the carbon footprint of milk by 0.0% to 6.7%. Results demonstrate that the largest consistent increase in dairy farm profitability did not result in significant reductions in the carbon footprint of milk, and the largest mitigation options did not provide a guarantee of being cost-neutral or better.

description: Features in the primordial scalar power spectrum provide a possible roadway to describe the outliers at the low multipoles in the WMAP data. Apart from the CMB angular power spectrum, these features can also alter the matter power spectrum and, thereby, the formation of the large scale structure. Carrying out a complete numerical analysis, we investigate the effects of primordial features on the formation rates of the halos. We consider a few different inflationary models that lead to features in the scalar power spectrum and an improved fit to the CMB data, and analyze the corresponding imprints on the formation of halos. Performing a Markov Chain Monte Carlo analysis with the WMAP seven year data and the SDSS halo power spectrum from LRG DR7 for the models of our interest, we arrive at the parameter space of the models allowed by the data. We illustrate that, inflationary potentials, such as the quadratic potential with sinusoidal modulations and the axion monodromy model, which generate certain repeated, oscillatory features in the inflationary perturbation spectrum, do not induce a substantial difference in the number density of halos at their best fit values, when compared with, say, a nearly scale invariant spectrum as is generated by the standard quadratic potential. However, we find that the number density and the formation rates of halos change by about 13-22% for halo masses ranging over 10^4-10^14 solar mass, for potential parameters that lie within 2-sigma around the best fit values arrived at from the aforesaid joint constraints. We briefly discuss the implications of our results.

description: Many human-related activities show power-law decaying interevent time distribution with exponents usually varying between 1 and 2. We study a simple task-queuing model, which produces bursty time series due to the nontrivial dynamics of the task list. The model is characterised by a priority distribution as an input parameter, which describes the choice procedure from the list. We give exact results on the asymptotic behaviour of the model and we show that the interevent time distribution is power-law decaying for any kind of input distributions that remain normalizable in the infinite list limit, with exponents tunable between 1 and 2. The model satisfies a scaling law between the exponents of interevent time distribution (alpha) and autocorrelation function (beta): alpha + beta = 2. This law is general for renewal processes with power-law decaying interevent time distribution. We conclude that slowly decaying autocorrelation function indicates long-range dependency only if the scaling law is violated.

title: Molecular Evidence for the Export of Terrigenous Organic Matter to the North Gulf of Mexico by Solid-State 13C NMR and Fourier Transform Ion Cyclotron Resonance Mass Spectrometry of Humic Acids

description: Marine organic matter is mainly believed to originate from autochthonous organic matter, while terrigenous organic matter is assumed to be largely degraded prior to reaching the open ocean or more recently replaced by marine organic matter via a stripping process. Sediment samples along a transect extending from the Mississippi River Birdsfoot Delta to the Mississippi Canyon on the Louisiana continental shelf were examined by advanced analytical techniques, electrospray ionization coupled to a 12T Fourier transform ion cyclotron resonance mass spectrometer (ESI-FTICR-MS) and quantitative solid-state multiple cross polarization magic angle spinning (multi-CPMAS) 13C NMR in an effort to understand the source and export of terrigenous organic matter to the Gulf of Mexico. Both NMR and mass spectral data indicate that condensed aromatics (CA) and carboxyl-containing aliphatic molecules (CCAM) are present at the mouth of the river, we suggest a high contribution from terrigenous soil-like organic matter. With seaward progression, CA mass spectral peak magnitudes diminish by 15% and, correspondingly, 30% of integrated NMR peak areas. In contrast, mass spectral and NMR CCAM peaks grow by 7 and 13% respectively. These trends suggest that data collected from this investigation using humic acid extracts shows molecular evidence of terrigenous organic matter deposited in offshore sediments.

description: In this Letter we study the effects of the Modified Uncertainty Principle as proposed in Ali et al. (2009) [5] in simple quantum mechanical systems and study its thermodynamic properties. We have assumed that the quantum particles follow Maxwell-Boltzmann statistics with no spin. We compare our results with the results found in the GUP and polymer quantum mechanical frameworks. Interestingly we find that the corrected thermodynamic entities are exactly same compared to the polymer results but the length scale considered has a theoretically different origin. Hence we express the need of further study for an investigation whether these two approaches are conceptually connected in the fundamental level.

Europäischer Investitionsschutz vor dem Aus?

description: Anfang März 2018 entschied der EuGH, dass Schiedsgerichte, die über unionsinterne bilaterale Investitionsschutzabkommen urteilen, nicht mit der „Autonomie der Unionsrechtsordnung“ vereinbar sind. Er begründete dies insbesondere mit der fehlenden „Gerichtsqualität“ eines Schiedsgerichts und der daraus resultierenden fehlenden Vorlageberechtigung i. S. v. Art. 267 AEUV. Der folgende Beitrag geht nun der Frage nach, ob dieses Grundsatzurteil auch Schiedsgerichte betrifft, die auf dem Übereinkommen zur Beilegung von Investitionsstreitigkeiten zwischen Staaten und den Angehörigen anderer Staaten beruhen und insofern vom internationalen Zentrum zur Beilegung von Investitionsstreitigkeiten (ICSID) administriert werden. In the beginning of March 2018 the European Court of Justice decided that arbitral tribunals, which rule over European bilateral investment treaties, are not compatible with EU law. The court mainly reasoned its decision with the missing competence of an arbitral tribunal to bring a case in front of the European Court of Justice according to Art. 267 AEUV. The following paper discusses the question, whether the decision of the European Court of Justice also affects arbitral tribunals which are based on the Convention on the Settlement of Investment Disputes between States and Nationals of other States and thus administered by the International Center for the Settlement of Investment Disputes (ICSID).

description: Charge transfer between metal nanoparticles and the supported TiO2 surface is primarily important for catalytic applications as it greatly affects the catalytic activity and the thermal stability of the deposited nanoparticles on the surface. Herein, a systematic spin-polarized density functional calculation is performed to evaluate the adsorption, diffusion, and charge state of several transition metal monomers on both stoichiometric and reduced rutile TiO2 (110) surface. The role of oxygen vacancy (Ov) with its accompanying excess electrons in influencing the activation of the monomers is examined. For pristine reduced surface, our hybrid functional calculation shows that only a small portion (around 5%) of the excess electrons occupy the topmost surface, which are mainly delocalized at the second nearest and third nearest fivefold coordinated Ti (Ti5c) atoms. The small amounts of excess electrons populating at the Ti5c atoms can be transferred to strongly electronegative adsorbates like Au and Pt thus enabling a moderate adsorption, whereas no stable adsorption at the Ti5c site is found for other less electronegative TM adatoms(Ag, Cu, Fe, Co, Ni and Pd) on the reduced surface and for all the adatoms on stoichiometric surface. This finding clarify the origin of the experimental observation of the adsorption of O2 and CO molecules at Ti5c sites in connection with charge transfer. In addition, the spatial redistribution of the excess electrons at Ti5c sites around the Ov upon the adsorption of the monomers is thoroughly examined. Our finding of an accumulation of excess electrons at the Ti5c sites around the monomers explains the critical role of the perimeter interface of the deposited nanoparticles in promoting the adsorption and activation of reactants observed in experiments.

Kleinteilige Entwicklungspotenziale im unbeplanten Innenbereich – ein automatisiertes Verfahren zur Baurechtsabschätzung nach § 34 BauGB

description: Angesichts der anhaltenden Wohnraum-Knappheit in vielen deutschen Wachstumsregionen ist die Frage nach den verbleibenden baulichen Entwicklungspotenzialen in den betroffenen Gemeinden von großer Bedeutung. Neben den Potenzialen, die eine aktive gemeindliche Planung erfordern, können Potenziale im unbeplanten Innenbereich nach § 34 BauGB bestehen.
 Obwohl mitunter ein großer Teil der baulichen Aktivitäten auf dieses Gebiet entfällt, sind die Kenntnisse über das zur Verfügung stehende Potenzial und die Dynamik dort meist sehr begrenzt. Dies erschwert das Aufzeigen quantitativer Szenarien zur langfristigen Wohnraumversorgung und kann problematisch sein, wenn planungsrelevante Entwicklungen nicht oder erst spät erkannt werden. Eine systematische „händische“ Baurechtserfassung größerer Gebiete ist aufgrund des Aufwands in der Regel nicht möglich. Eine Alternative sind geodatenbasierte Ansätze, die das Baurecht automatisiert abschätzen.
 Die vorliegende Publikation stellt einen solchen Ansatz am Beispiel der Stadt München vor. Die Landeshauptstadt München befindet sich seit mehr als 20 Jahren in einer Wachstumsphase und hat heute knapp 1,6 Mio. Einwohner*innen. Der unbeplante Innenbereich macht etwa ein Drittel der gesamten Stadtfläche aus. Das neu entwickelte Verfahren setzt auf einem Geoinformationssystem auf und überführt die gesetzlichen Regelungen in einen formellen Computer-Algorithmus. Jedes Flurstück wird als rechtlicher Rahmen für eine Entwicklung einzeln betrachtet. Je Betrachtungs-Flurstück identifiziert der Algorithmus mögliche Bezugsfall-Flurstücke auf Grundlage fest definierter Kriterien. Ist unter den möglichen Bezugsfällen ein Flurstück mit einer größeren Geschossfläche zu finden, geht der Algorithmus davon aus, dass diese auch auf dem Betrachtungs-Flurstück baurechtskonform umsetzbar ist. Aus der Differenz der aktuellen Geschossfläche zur Geschossfläche des Bezugsfalls ergibt sich das Baurechtspotenzial.
 Ein Abgleich des so berechneten Baurechts mit einer Stichprobe von „händisch“ ausgewerteten Flurstücken zeigt eine gute Übereinstimmung in Gebieten mit Ein- und Mehrfamilienhäusern und in Gründerzeitvierteln. Das vorgestellte Verfahren bietet eine gute Ersteinschätzung und kann in aggregierter Form allein oder in Kombination mit anderen Daten wertvolle Erkenntnisse für eine vorausschauende Stadtentwicklungsplanung liefern.
