description: Der Anteil von Kindern, die eine Privatschule besuchen, hat sich seit Beginn der 1990er Jahre fast verdoppelt: Mittlerweile gehen gut neun Prozent aller SchülerInnen in Deutschland auf eine Privatschule. In Ostdeutschland liegt ihr Anteil mit etwas mehr als zehn Prozent inzwischen über dem Anteil in Westdeutschland (knapp neun Prozent). Wie dieser Bericht auf Basis von Daten des Sozio-oekonomischen Panels (SOEP) zeigt, spielt die Bildung der Eltern sowohl in west- als auch in ostdeutschen Bundesländern eine immer größere Rolle für die Privatschulnutzung. In Ostdeutschland gehen gut 23 Prozent aller SchülerInnen aus Akademikerelternhäusern auf eine Privatschule, in Westdeutschland knapp 17 Prozent – rund 20 beziehungsweise 13 Prozentpunkte mehr als 1995. In Ostdeutschland werden auch mit Blick auf die Haushaltseinkommen die Unterschiede in der Privatschulnutzung immer größer. Die soziale Segregation zwischen den privaten und öffentlichen Schulen hat über die Zeit also deutlich zugenommen. Um dem entgegenzuwirken, sind unterschiedliche Maßnahmen denkbar. Mehr Bundesländer als bisher könnten zum Beispiel das Schulgeld begrenzen und eine konkrete Einkommensstaffelung vorschreiben. Zudem könnten Maßnahmen ergriffen werden, die öffentliche Schulen für Familien mit einer höheren Bildung wieder attraktiver machen.

description: Majorana Fermions, strange particles that are their own antiparticles, were predicted in 1937 and have been sought after ever since. In condensed matter they are predicted to exist as vortex core or edge excitations in certain exotic superconductors. These are topological superconductors whose order parameter phase winds non-trivially in momentum space. In recent years, a new and promising route for realizing topological superconductors has opened due to advances in the field of topological insulators. Current proposals are based on semiconductor heterostructures, where spin-orbit coupled bands are split by a band gap or Zeeman field and superconductivity is induced by proximity to a conventional superconductor. Topological superconductivity is obtained in the interface layer. The proposed heterostructures typically include two or three layers of different materials. In the current work we propose a device based on materials with inherent spin-orbit coupling and an intrinsic tendency for superconductivity, eliminating the need for a separate superconducting layer. We study a lattice model that includes spin-orbit coupling as well as on-site and nearest neighbor interaction. Within this model we show that topological superconductivity is possible in certain regions of parameter space. These regions of non-trivial topology can be understood as a nodeless superconductor with d-wave symmetry which, due to the spin-orbit coupling, acquires an extra phase twist of $2π$.

description: The next-to-leading order analysis of the cross section of hadronic gluino pair production close to threshold is presented. Within the framework of non-relativistic QCD a significant enhancement compared to fixed order perturbation theory is observed which originates from the characteristic remnant of the 1S peak below the nominal pair threshold. This enhancement is similar to the corresponding one for top production. However, as a consequence of the larger colour factor of the QCD potential the effect is significantly enhanced. The analysis includes all colour configurations of S-wave gluino pairs, i.e. singlet, symmetric and antisymmetric octet, decuplet and twenty-seven representation. Matching coefficients involving real and virtual radiation are separately evaluated for all colour and spin configurations and initial states. We concentrate on the case of gluino decay rates comparable to the gluino binding energy. The non-relativistic dynamics of the gluino pair is solved by calculating the Green's function in NLO. Numerical results for the Large Hadron Collider at sqrt(s)=14 TeV and 7 TeV are presented for various characteristic scenarios.

Impossibility of the Efimov effect for p-wave interactions

description: Whether the Efimov effect is possible, in principle, for p-wave or higher partial-wave interactions is a fundamental question. Recently, there has been a claim that three nonrelativistic particles with resonant p-wave interactions exhibit the Efimov effect. We point out that the assumed p-wave scattering amplitude inevitably causes a negative probability. This indicates that the Efimov states found there cannot be realized in physical situations. We also restate our previous argument that the Efimov effect, defined as an infinite tower of universal bound states characterized by discrete scale invariance, is impossible for p-wave or higher partial-wave interactions.

description: By introducing diffeomorphism and local Lorentz gauge invariant holonomy fields, we study in the recent article [S.-S. Xue, Phys. Rev. D82 (2010) 064039] the quantum Einstein-Cartan gravity in the framework of Regge calculus. On the basis of strong coupling expansion, mean-field approximation and dynamical equations satisfied by holonomy fields, we present in this Letter calculations and discussions to show the phase structure of the quantum Einstein-Cartan gravity, (i) the order phase: long-range condensations of holonomy fields in strong gauge couplings; (ii) the disorder phase: short-range fluctuations of holonomy fields in weak gauge couplings. According to the competition of the activation energy of holonomy fields and their entropy, we give a simple estimate of the possible ultra-violet critical point and correlation length for the second-order phase transition from the order phase to disorder one. At this critical point, we discuss whether the continuum field theory of quantum Einstein-Cartan gravity can be possibly approached when the macroscopic correlation length of holonomy field condensations is much larger than the Planck length.

description: Die Jahre des überdurchschnittlichen Wachstums der deutschen Wirtschaft sind vorbei – unter dem Strich steht sie aber weiterhin nicht schlecht da. Zwar wird das hiesige Bruttoinlandsprodukt in diesem Jahr mit 1,5 Prozent deutlich weniger zunehmen als noch zu Jahresbeginn erwartet. Sorgen vor einer unmittelbar bevorstehenden Rezession dürften angesichts einer robusten Auslandsnachfrage und des anhaltenden Beschäftigungsaufbaus aber der Einschätzung weichen, dass sich nach Jahren des überdurchschnittlichen Wachstums das Tempo der deutschen Wirtschaft normalisiert. Der allmähliche Abbau der gut ausgelasteten Kapazitäten geht mit geringeren Zuwächsen des Bruttoinlandsprodukts einher; dies wird kurzfristig aber noch durch Nachholeffekte in der Automobilindustrie nach den Produktions- und Auslieferungsproblemen und durch die finanzpolitischen Einkommensschübe zum Jahresbeginn 2019 – Stichwort Sozialversicherungsbeiträge – überlagert werden.

description: Im dritten Quartal hat sich der globale Aufschwung etwas abgeschwächt, während die Abwärtsrisiken bis zuletzt zugenommen haben. Das DIW Berlin prognostiziert – nahezu unverändert – eine Expansion der weltwirtschaftlichen Produktion in Höhe von 4,3 Prozent für das Jahr 2018 und von 3,9 Prozent für 2019. Im Jahr 2020 wird sich die globale konjunkturelle Dynamik mit 3,6 Prozent abermals leicht verlangsamen. In einigen Ländern trugen Sonderfaktoren zur wirtschaftlichen Abschwächung bei. In den großen entwickelten Volkswirtschaften bleibt der private Konsum aufgrund der guten Arbeitsmarktlage die Hauptstütze der Konjunktur. Dagegen leiden die Investitionen der Unternehmen und der Außenhandel zunehmend unter den derzeit großen politischen Unwägbarkeiten. Brexit und Italien-Krise bergen Risiken für die Investitionen sowie den Konsum, und im Falle einer Eskalation des Handelsstreits besteht auch die Gefahr einer weltwirtschaftlichen Rezession. Die Geldpolitik dürfte global vorerst expansiv ausgerichtet bleiben. Von der Finanzpolitik sind keine nennenswerten Stimuli mehr zu erwarten, zumal die staatlichen Maßnahmen in den USA im Prognosezeitraum auslaufen.

description: We report the first results of a long term program aiming to provide accurate independent estimates of the Hubble constant (H0) using the L-sigma distance estimator for Giant extragalactic HII regions (GEHR) and HII galaxies. We have used VLT and Subaru high dispersion spectroscopic observations of a local sample of HII galaxies, identified in the SDSS DR7 catalogue in order to re-define and improve the L(Hbeta)-sigma distance indicator and to determine the Hubble constant. To this end we utilized as local calibration or `anchor' of this correlation, GEHR in nearby galaxies which have accurate distance measurements determined via primary indicators. Using our best sample of 69 nearby HII galaxies and 23 GEHR in 9 galaxies we obtain H0=74.3 +- 3.1 (statistical) +- 2.9 (systematic) km /s Mpc, in excellent agreement with, and independently confirming, the most recent SNe Ia based results.

description: Abstract
Studies on housing and settlements have been widely conducted in various countries, with varying focuses. This research uses a policy perspective with a research focus on the Study of Permanent Housing Development for Earthquake-Affected Communities in Cianjur Regency. A magnitude 5.2 earthquake shook the Cianjur region on Monday, November 21, 2022. The Cianjur earthquake caused hundreds of casualties, people's homes were destroyed, and not a few roads were cracked because they were not strong enough to withstand the shock. The Metereology, Climatology and Geophysics Agency (BMKG) revealed that the earthquake originated from the movement of the Cugenang fault. Reporting from the Instagram account of the Regional Disaster Management Agency (BPBD) of Cianjur Regency, as many as 593 people were seriously injured and 114,683 residents were forced to evacuate. As for other damage data, BPBD recorded 16 sub-districts consisting of 169 affected villages. Housing and Settlement Infrastructure Development Policy for Earthquake-Affected Communities in Cianjur Regency includes using post-disaster rehabilitation and reconstruction activities as a means to build communities and stimulate the social and economic life of the community with the principles of sustainable development and disaster risk reduction. In residential relocation, environmental infrastructure and public and social facilities are still needed.

description: In diesem Wochenbericht wird zunächst eine Bestandsaufnahme aktueller Entwicklungen auf dem globalen Rohölmarkt vorgenommen. Marktdaten weisen darauf hin, dass der Ölmarkt trotz der US-Sanktionen gegen iranische Ölexporte derzeit gut versorgt ist. Insbesondere die weiter expandierende US-Schieferölförderung sorgt für Zuwächse auf der Angebotsseite. Mithilfe von Simulationsrechnungen wird zudem ein Ausblick auf mögliche kurzfristige Ölpreiseffekte in Folge der Iran-Sanktionen gegeben. Demnach wäre bei voller Wirksamkeit der Sanktionen im Jahr 2019 ein Preisanstieg von weniger als 20 US-Dollar pro Fass Rohöl zu erwarten. Der Preiseffekt ist geringer, falls z. B. die USA ihre Schieferölförderung kurzfristig ausweiten oder die Sanktionen nur unvollständig durchgesetzt werden können. Weitere angebots- und nachfrageseitige Unsicherheiten, die im Modell nicht abgebildet werden, könnten jedoch zu stärkeren Preiseffekten führen. Unabhängig von kurzfristigen Preisentwicklungen stellt sich längerfristig die Herausforderung, den globalen Ölverbrauch mit den Klimaschutzzielen in Einklang zu bringen.

description: Eine häufig geäußerte Kritik im digitalen Zeitalter ist, dass zu viel Macht in den Händen weniger Einzelner liegt. Eine demokratische und am Gemeinwohl ausgerichtete kommunikative Infrastruktur, vor allem auf sozialen Plattformen, steht den Geschäftsmodellen großer kommerzieller Plattformen fundamental entgegen. In der Diskussion um gemeinwohlorientierte Alternativen gewinnt deshalb das sogenannte Fediverse zunehmend an Relevanz. Der Begriff Fediverse setzt sich aus den englischen Wörtern „federation“ und „universe“ zusammen und bezeichnet einen Zusammenschluss föderierter, sozialer Netzwerke und anderer Online-Dienste, die alle unabhängig, aber miteinander kompatibel sind. 

Dezentrale Kommunikationsräume versprechen die dominanten Machtverhältnisse aufzubrechen. Entscheidungen über technische Ausgestaltung, Nutzer:innenmanagement und Inhaltsmoderation werden auf eine Vielzahl von Instanzen und deren jeweilige Betreiber:innen verteilt und folgen nicht mehr primär gewinnorientierten Logiken. Der Fokus soll wieder auf Kommunikation und Interkation gerichtet werden, statt die Gewinnmaximierung der Plattformökonomie voranzutreiben.

description: We have studied the electronic properties in aperiodic graphene superlattices of Thue-Morse sequence. Although the structure is aperiodic, an unusual Dirac point (DP) does exist and its location is exactly at the position of the zero-averaged wave number (zero-$\bar{k})$. Furthermore, the zero-$\bar{k}$ gap associated with the DP is robust against the lattice constants and the incident angles, and multi-DPs can appear under the suitable conditions. A resultant controllability of electron transport in Thue-Morse sequence is predicted, which may facilitate the development of many graphene-based electronics.

description: In the frame work of a nuclear overlap model, we estimate the number of nucleon and quark participants in proton-proton, proton-nucleus and nucleus-nucleus collisions. We observe the number of nucleon ($N_{N-part}$)-normalized enhancement of multi-strange particles which show a monotonic increase with centrality, turns out to be a centrality independent scaling behavior when normalized to number of constituent quarks participating in the collision ($N_{q-part}$). In addition, we observe that the $N_{q-part}$-normalized enhancement, when further normalized to the strangeness content, shows a strangeness independent scaling behavior. This holds good at top RHIC energy. However, the corresponding SPS data show a weak $N_{q-part}$-scaling with strangeness scaling being violated at top SPS energy. This scaling at RHIC indicates that the partonic degrees of freedom playing an important role in the production of multi-strange particles. Top SPS energy, in view of the above observations, shows a co-existence of hadronic and partonic phases. We give a comparison of data with HIJING, AMPT and UrQMD models to understand the particle production dynamics at different energies.

description: Das aktuelle Regelwerk zur Bankenregulierung erlaubt ein Risikogewicht von null für EU-Staatsanleihen. Seit der europäischen Verschuldungskrise wird verstärkt über die Aufhebung des Eigenkapitalprivilegs gestritten, weil die Nullgewichtung als ein Grund für die engen Verbindungen zwischen den Risiken von Staaten und Banken gesehen wird. Dieser Bericht analysiert die Entwicklung des Home Bias – also der Neigung der europäischen Großbanken, überproportional in Staatsanleihen des Heimatlandes zu investieren – für Deutschland, Frankreich, das Vereinigte Königreich, Italien und Spanien. Außerdem wird der potentielle Eigenkapitalbedarf für den Fall der Abschaffung der Nullgewichtung von Staatsanleihen bestimmt. Es zeigt sich, dass der Home Bias in den letzten vier Jahren bei vielen europäischen Großbanken zugenommen hat. Auf den zusätzlichen Eigenkapitalbedarf wirkt sich der Home Bias nur bei spanischen und italienischen Banken aus, da deren Heimatstaaten eine vergleichsweise schwache Ratingnote haben. Die Abschätzung des zusätzlichen Eigenkapitalbedarfs im Falle der Aufhebung des Eigenkapitalprivilegs zeigt für die italienischen Banken mit 11,5 Milliarden Euro den höchsten Kapitalbedarf an, gefolgt von den spanischen Banken mit 9,5 Milliarden Euro. Damit würde die Abschaffung des Eigenkapitalprivilegs die Finanzierung der Staatsschulden in Italien und Spanien deutlich erschweren. Es wäre daher empfehlenswert, die Risikogewichtung für Staatsanleihen erst nach der Stabilisierung der Staatsverschuldung einzuführen. Gleichzeitig sollten Maßnahmen ergriffen werden, die es den Banken erleichtern, ihren Home Bias abzubauen und ihr Staatsanleihenportfolio besser zu diversifizieren

By including a fugacity $t$ on some suitable bonds, one interpolates between the triangular lattice (t=1) and the square lattice (t=0). The wave function is known to be a massive $\mathbb Z_2$ topological liquid for $t>0$ whereas it is a gapless critical state at t=0. We mainly consider two geometries for the subsystem: that of a semi-infinite cylinder, and the disk-like setup proposed by Kitaev and Preskill [Phys. Rev. Lett. 96, 110404 (2006)]. In the cylinder case, the entropies contain an extensive term -- proportional to the length of the boundary -- and a universal sub-leading constant $s_n(t)$. Fitting these cylinder data (up to a perimeter of L=32 sites) provides $s_n$ with a very high numerical accuracy ($10^{-9}$ at t=1 and $10^{-6}$ at $t=0.5$). In the topological $\mathbb{Z}_2$ liquid phase we find $s_n(t>0)=-\ln 2$, independent of the fugacity $t$ and the Rényi parameter $n$. At t=0 we recover a previously known result, $s_n(t=0)=-(1/2)\ln(n)/(n-1)$ for $n<1$ and $s_n(t=0)=-\ln(2)/(n-1)$ for $n>1$. In the disk-like geometry -- designed to get rid of the boundary contributions -- we find an entropy $s^{\rm KP}_n(t>0)=-\ln 2$ in the whole massive phase whatever $n>0$, in agreement with the result of Flammia {\it et al.} [Phys. Rev. Lett. 103, 261601 (2009)]. Some results for the gapless limit $R^{\rm KP}_n(t\to 0)$ are discussed.

Diversity and evolution of single-stranded DNA viruses in marine environments

description: Viruses are the most abundant and genetically diverse life forms in the biosphere. By infecting specific subsets of microbial communities, they influence community composition, thereby affecting nutrient and energy cycling. Single-stranded (ss) DNA viruses are major pathogens of plants and animals that have been well studied for years due to their economic and human-health effects. Recent advances in metagenomics show that marine ssDNA viruses are widespread in marine and freshwater environments, but their diversity and evolutionary relationships remain relatively unexplored. This dissertation focuses on characterizing the diversity and evolutionary relationships among marine ssDNA viruses. First, metagenomic data were gathered and analyzed to assess the genetic diversity of ssDNA viruses, leading to the identification 129 genetically distinct groups of ssDNA viruses that had no recognizable similarity to each other or to other sequenced viruses. Each group was represented by at least one complete genome, with most falling into 11 well-defined groups. Comparison and phylogenetic analysis of sequences from marine and terrestrial viruses indicate that ssDNA viruses share a common origin and that terrestrial viruses likely co-evolved with their hosts when they transitioned from the ocean to the land. The second part focused on one particular subfamily of viruses, the Gokushovirinae (family Microviridae) to understand their relationship with the environment. Five complete genomes were assembled and primers were designed to amplify a fragment of the major capsid protein to look at the distribution of gokushoviruses in various marine environments. Phylogenetic analysis revealed that most sequences were distantly related to those from cultured representatives, falling into many new distinct evolutionary groups. Finally, a protocol for fluorescence in situ hybridization was developed to observe cells infected by gokushoviruses. The results presented in this dissertation greatly expand the known sequence space for ssDNA, nearly doubling the number of complete available genomes, and revealing much greater genetic richness than previously though. The vast diversity of ssDNA viruses in the sea and their similarity with viruses infecting eukaryotes is consistent with their role as significant pathogens of marine phytoplankton and microzooplankton.

description: We construct gauge theory of SU(3)xSU(2)xU(1) by spectral cover from F-theory and ask how the Standard Model is extended under minimal assumptions on Higgs sector. For the requirement on different numbers between Higgs pairs and matter generations (respectively one and three) distinguished by R-parity, we choose a universal G-flux obeying SO(10) but slightly breaking E_6 unification relation. This condition forces distinction between up and down Higgs fields, suppression of proton decay operators up to dimension five, and existence and dynamics of a singlet related to mu-parameter.

Grassmannian Differential Limited Feedback for Interference Alignment

description: Channel state information (CSI) in the interference channel can be used to precode, align, and reduce the dimension of interference at the receivers, to achieve the channel's maximum multiplexing gain, through what is known as interference alignment. Most interference alignment algorithms require knowledge of all the interfering channels to compute the alignment precoders. CSI, considered available at the receivers, can be shared with the transmitters via limited feedback. When alignment is done by coding over frequency extensions in a single antenna system, the required CSI lies on the Grassmannian manifold and its structure can be exploited in feedback. Unfortunately, the number of channels to be shared grows with the square of the number of users, creating too much overhead with conventional feedback methods. This paper proposes Grassmannian differential feedback to reduce feedback overhead by exploiting both the channel's temporal correlation and Grassmannian structure. The performance of the proposed algorithm is characterized both analytically and numerically as a function of channel length, mobility, and the number of feedback bits. The main conclusions are that the proposed feedback strategy allows interference alignment to perform well over a wide range of Doppler spreads, and to approach perfect CSI performance in slowly varying channels. Numerical results highlight the trade-off between the frequency of feedback and the accuracy of individual feedback updates.
