description: It is often presumed, that life evolves relatively fast on planets with clement conditions, at least in its basic forms, and that extended periods of habitability are subsequently needed for the evolution of higher life forms. Many planets are however expected to be only transiently habitable. On a large set of otherwise suitable planets life will therefore just not have the time to develop on its own to a complexity level as it did arise on earth with the cambrian explosion. The equivalent of a cambrian explosion may however have the chance to unfold on transiently habitable planets if it would be possible to fast forward evolution by 3-4 billion years (with respect to terrestrial timescales). We argue here, that this is indeed possible when seeding the candidate planet with the microbial lifeforms, bacteria and unicellular eukaryotes alike, characterizing earth before the cambrian explosion. An interstellar mission of this kind, denoted the `Genesis project', could be carried out by a relatively low-cost robotic microcraft equipped with a on-board gene laboratory for the in situ synthesis of the microbes. We review here our current understanding of the processes determining the timescales shaping the geo-evolution of an earth-like planet, the prospect of finding Genesis candidate planets and selected issues regarding the mission layout. Discussing the ethical aspects connected with a Genesis mission, which would be expressively not for human benefit, we will also touch the risk that a biosphere incompatibility may arise in the wake of an eventual manned exploration of a second earth.

description: Suburbanisierung ist der Prozess, der die Stadtentwicklung in Deutschland im 20. Jahrhundert dominiert hat. Auch wenn in den letzten Jahren eine Abschwächung der Suburbanisierung bei gleichzeitiger neuer Attraktivität der Kernstädte als Wohnstandort zu beobachten ist, zeigt sich, dass sich die mit Suburbanisierungsprozessen verbundenen planerischen Herausforderungen damit keineswegs von selbst lösen. Diese Arbeit zeigt auf, an welchen Stellschrauben neue Gegenstrategien zur Begrenzung der Suburbanisierung ansetzen können. Die Suburbanisierung ist als emergenter Prozess nicht das Ergebnis räumlicher Planung, sondern das Resultat unzähliger Einzelentscheidungen einer Vielzahl an Akteuren, die in einem komplexen Wirkungszusammenhang stehen, aber in ihrer Gänze von niemandem bewusst gesteuert werden. Ansätze zur Begrenzung der Suburbanisierung müssen daher bei den Entscheidungslogiken der handelnden Akteure ansetzen. Die Arbeit greift eine wesentliche Akteursgruppe in Suburbanisierungsprozessen, die Stadt-Umland-Wanderer, heraus und zielt darauf ab, aus einer handlungstheoretischen Mikroperspektive zu einem tiefergreifenderen Verständnis der Entscheidungs- und Handlungslogiken der Stadt-Umland-Wanderer bei der Wohnstandortwahl beizutragen. Die Arbeit gibt methodische Empfehlungen, wie sich der Entscheidungsprozess der Stadt-Umland-Wanderer bei der Wohnstandortwahl in standardisierten Wanderungsmotivstudien angemessen erheben lässt und leistet auf der Grundlage einer quantitativen sowie einer qualitativen Wanderungsmotivuntersuchung für vier Fallregionen (Köln, Leipzig, Magdeburg und Münster) einen empirischen Beitrag zu drei Forschungslücken: einer regional vergleichenden Analyse der Muster und Motive der Stadt-Umland-Wanderung, Informations- und Wahrnehmungslücken der Stadt-Umland-Wanderer bei der Wohnstandortwahl sowie der Identifizierung durch städtische Gegenstrategien beeinflussbarer Stadt-Umland-Wanderer. Abschließend werden, auf den analytischen Erkenntnissen aufbauend, grundsätzliche planerische Schlussfolgerungen zur Begrenzung von Suburbanisierungsprozessen gezogen.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: The goal of this article is to review the progress of three-electron spin qubits from their inception to the state of the art. We direct the main focus towards the resonant exchange (RX) qubit and the exchange-only qubit, but we also discuss other qubit implementations using three electron spins. For each three-spin qubit we describe the qubit model, the physical realization, the implementations of single-qubit operations, as well as the read-out and initialization schemes. Two-qubit gates and decoherence properties are discussed for the RX qubit and the exchange-only qubit, thereby, completing the list of requirements for a viable candidate qubit implementation for quantum computation. We start with describing the full system of three electrons in a triple quantum dot, then discuss the charge-stability diagram and restrict ourselves to the relevant subsystem, introduce the qubit states, and discuss important transitions to other charge states. Introducing the various qubit implementations, we begin with the exchange-only qubit, followed by the spin-charge qubit, the hybrid qubit, and the RX qubit, discussing for each the single-qubit operations, read-out, and initialization methods, whereas the main focus will be on the RX qubit, whose single-qubit operations are realized by driving the qubit at its resonant frequency in the microwave range similar to electron spin resonance. Two different types of two-qubit operations are presented for the exchange-only and the RX qubit which can be divided into short-ranged and long-ranged interactions. Both of these interaction types can be expected to be necessary in a large-scale quantum computer. We also take into account the decoherence of the qubit through the influence of magnetic noise as well as dephasing due to charge noise.

description: In this article we propose a new test for additivity in nonparametric quantile regression with a high dimensional predictor. Asymptotic normality of the corresponding test statistic (after appropriate standardization) is established under the null hypothesis, local and fixed alternatives. We also propose a bootstrap procedure which can be used to improve the approximation of the nominal level for moderate sample sizes. The methodology is also illustrated by means of a small simulation study, and a data example is analyzed.

description: The Precision IceCube Next Generation Upgrade (PINGU) is a proposed low-energy in-fill extension to the IceCube Neutrino Observatory. With detection technology modeled closely on the successful IceCube example, PINGU will provide a 6Mton effective mass for neutrino detection with an energy threshold of a few GeV. With an unprecedented sample of over 60,000 atmospheric neutrinos per year in this energy range, PINGU will make highly competitive measurements of neutrino oscillation parameters in an energy range over an order of magnitude higher than long-baseline neutrino beam experiments. PINGU will measure the mixing parameters $θ_{\rm 23}$ and $Δm^2_{\rm 32}$, including the octant of $θ_{\rm 23}$ for a wide range of values, and determine the neutrino mass ordering at $3σ$ median significance within 4 years of operation. PINGU's high precision measurement of the rate of ${ν_τ}$ appearance will provide essential tests of the unitarity of the $3\times 3$ PMNS neutrino mixing matrix. PINGU will also improve the sensitivity of searches for low mass dark matter in the Sun, use neutrino tomography to directly probe the composition of the Earth's core, and improve IceCube's sensitivity to neutrinos from Galactic supernovae. Reoptimization of the PINGU design has permitted substantial reduction in both cost and logistical requirements while delivering performance nearly identical to configurations previously studied. This document summarizes the results of detailed studies described in a more comprehensive document to be released soon.

description: Recently Weyl fermions have attracted increasing interest in condensed matter physics due to their rich phenomenology originated from their nontrivial monopole charges. Here we present a theory of real Dirac points that can be understood as real monopoles in momentum space, serving as a real generalization of Weyl fermions with the reality being endowed by the $PT$ symmetry. The real counterparts of topological features of Weyl semimetals, such as Nielsen-Ninomiya no-go theorem, $2$D sub topological insulators and Fermi arcs, are studied in the $PT$ symmetric Dirac semimetals, and the underlying reality-dependent topological structures are discussed. In particular, we construct a minimal model of the real Dirac semimetals based on recently proposed cold atom experiments and quantum materials about $PT$ symmetric Dirac nodal line semimetals.

description: In this work, we investigate the implications of the Integrated Galaxy-wide stellar Initial Mass Function (IGIMF) approach in the framework of the semi-analytic model GAEA (GAlaxy Evolution and Assembly), which features a detailed treatment of chemical enrichment and stellar feedback. The IGIMF provides an analytic description of the dependence of the stellar IMF shape on the rate of star formation in galaxies. We find that our model with a universal IMF predicts a rather flat [$α$/Fe]-stellar mass relation. The model assuming the IGIMF, instead, is able to reproduce the observed increase of $α$-enhancement with stellar mass, in agreement with previous studies. This is mainly due to the fact that massive galaxies are characterized by larger star formation rates at high-redshift, leading to stronger $α$-enhancement with respect to low-mass galaxies. At the same time, the IGIMF hypothesis does not affect significantly the trend for shorter star formation timescales for more massive galaxies. We argue that in the IGIMF scenario the [$α$/Fe] ratios are good tracers of the highest star formation events. The final stellar masses and mass-to-light-ratio of our model massive galaxies are larger than those estimated from the synthetic photometry assuming a universal IMF, providing a self-consistent interpretation of similar recent results, based on dynamical analysis of local early type galaxies.

description: Background: Tuberculosis (TB) and cancer are two major public health problems associated with significant morbidity and mortality. TB is one of the major causes of death amongst infectious diseases and it is estimated that one-third of the human population is infected with Mycobacterium tuberculosis .The burden of cancer is increasing globally. Co morbid conditions influence the survival of cancer patients. Objectives: The objective of this study is to evaluate the burden of pulmonary TB/Rf resistance Tb,co morbid disease and associated risk factors among patients with all types of malignancies visiting the oncology unit of Tikur Anbessa Hospital Methods: A Cross sectional study was performed in Tikur Anbessa Specialized Hospital from May 2017 to April 2018. Convenience sampling methods was used. Sputum sample was collected from all patients with malignancy that had cough. The sputum was treated with NaOH and isopropanol at a ratio of 2:1then added in to cartridge for Xpert test. Smear was prepared for conventional microscopy. Results: A total of 206 patients with cancer were enrolled. Of these patients, 82 were male. Median age was 49 years, and range was from 18 to 80 years. 76 (36.9%) patients diagnosed with lung cancers; 20 (9.7%) had breast cancer; 18(8.7%) had hematologic malignancy; 17 (8.2%) patients had thyroid cancer; 15(7.3%) had Cervical ca; 13 (6.3%) esophageal cancer 11 (5.3%), colon cancer 9 (4.4%) Adenocarcinoma 8(3.9%) patients with Nasoparyngial cancer 7 (3.4%) had gastric cancer; 7(3.4%) and 12(5.8%) pancreatic carcinoma. During the study period, 6 patients developed tuberculosis .The prevalence rate of tuberculosis in the general population was 192 per 100,000 p, and the prevalence rate tuberculosis in the population with diagnosed malignancies was 2912 per 100,000 p. Conclusion and recommendation: Patient with anti cancer treatment was more likely to develop tuberculosis than a patient without treatment. Patients on chemotherapy or on steroid for longer period of time (6-11months) are in more risk than who had for 24 months and more or not taken at all. Recognition, timely prevention and control of tuberculosis and associated factors may reduce morbidity and mortality in malignant patients.

description: We consider a one-dimensional diffusion whose drift contains a deterministic periodic signal with unknown periodicity $T$ and carrying some unknown $d$-dimensional shape parameter $θ$. We prove Local Asymptotic Normality (LAN) jointly in $θ$ and $T$ for the statistical experiment arising from continuous observation of this diffusion. The local scale turns out to be $n^{-1/2}$ for the shape parameter and $n^{-3/2}$ for the periodicity which generalizes known results about LAN when either $θ$ or $T$ is assumed to be known.

description: We apply a recently advocated simulation scheme that employs a local order-parameter pinning field to study quantum critical phenomena in the two-dimensional square-lattice bilayer quantum Heisenberg model. Using a world-line quantum Monte Carlo approach, we show that for this model, the pinning-field approach allows to locate the quantum critical point over a wide range of pinning-field strengths. However, the identification of the quantum critical scaling behavior is found to be hard since the pinning field introduces strong corrections to scaling. In order to further elucidate the scaling behavior in this situation, we also study an improved classical lattice model in the three-dimensional Ising universality class by means of Monte Carlo simulations on large lattice sizes, which allow us to employ refined finite-size scaling considerations. A renormalization group analysis exhibits the presence of an important crossover effect from the zero pinning-field to a critical adsorption fixed point. In line with field-theoretical results, we find that at the critical adsorption fixed point the short-distance expansion of the order-parameter profile exhibits a new universal critical exponent. This result also implies the presence of slowly decaying scaling corrections, which we analyze in detail.

description: Diarrhea is a common complication and manifestation of HIV/AIDS, occurring in almost 90% of HIV/AIDS infections both in adults and children in developing countries like Ethiopia. Salmonella and Shigella infections are major global public health problems causing mild to severe forms of intestinal tract infection and diarrhea; Intestinal parasites are also additional burden in developing countries. Objective: To determine the prevalence of intestinal parasites, Salmonella and Shigella Species and their antimicrobial susceptibility pattern among HIV infected and non-infected patients with diarrhea in selected health facilities, Dessie town, Northeast Amhara Regional State. Methods: Health facility based cross sectional study was conducted at Dessie Referral Hospital, Dessie Health Center and Banbua wuha Health Center from January 2018 to April 2018. A total of 354 HIV infected and non-infected diarrheic outpatients were included using convenient sampling technique. Data on socio-demographic and clinical characteristics were collected using interview that employed structured questionnaire. Freshly voided stool specimen was used for investigate intestinal parasite, culturing and antimicrobial susceptibility testing. Data was entered and analyzed using SPSS software version 22 (IBM). Results: Among 354 study participants, 112 were HIV infected and 242 were non HIV infected with diarrhea. The prevalence of Intestinal parasite and Bacterial infection among HIV infected was 26(23.2%) and 8(7.1%), respectively. Of the bacterial isolates, Salmonella accounts 6(5.4%) followed by Shigella 2(1.8%) among bacterial isolates. Moreover, the most prevalent parasite was C. parvum 9(8%), E. histolytica/dispar 8(7.1%), 4(3.6%) and 1(0.9%) co-infection of C. parvum and C. catananyesis. The bacterial isolates from diarrheal patients were 100% susceptible to Ceftriaxone 95.4% susceptible to Ciprofloxacin However, the isolates 100% resistant to Ampicillin and Amoxicillin. Conclusion: High prevalence of enteric pathogens and high resistance of isolates to commonly prescribed antibiotics were observed from HIV infected and non-infected patients. Therefore, Prevention methods should be given attention to reduce the infection rate and AST should be practiced in the health facilities to select appropriate antimicrobial agent and prevent emergence of drug resistant bacteria.

description: Master equations of Lindblad type have attained prominent status in the fields of quantum optics and quantum information since they are guaranteed to satisfy fundamental notions of quantum dynamics such as complete positivity. When Lindblad operators are used to describe thermal reservoirs in contact with an open quantum system, the fundamental laws of thermodynamics and the fluctuation-dissipation theorem provide additional mandatory criteria. We show several examples of innocent-looking Lindblad operators which have questionable properties in this regard. Compatibility criteria between Hamiltonian and Lindblad terms as well as consequences of their violation are discussed. An alternative stochastic approach to dissipative quantum dynamics is outlined and illustrated through a harmonic-chain model for which the approach of local Lindblad operators fails.

description: The four-dimensional effective theory for type IIB warped flux compactifications proposed in [1] is completed by taking into account the backreaction of the Kähler moduli on the three-form fluxes. The only required modification consists in a flux-dependent contribution to the chiral fields parametrising the Kähler moduli. The resulting supersymmetric effective theory satisfies the no-scale condition and consistently combines previous partial results present in the literature. Similar results hold for M-theory warped compactifications on Calabi-Yau fourfolds, whose effective field theory and Kähler potential are also discussed.

description: We demonstrate continuous measurement and coherent control of the collective spin of an atomic ensemble undergoing Larmor precession in a high-finesse optical cavity. The coupling of the precessing spin to the cavity field yields phenomena similar to those observed in cavity optomechanics, including cavity amplification, damping, and optical spring shifts. These effects arise from autonomous optical feedback onto the atomic spin dynamics, conditioned by the cavity spectrum. We use this feedback to stabilize the spin in either its high- or low-energy state, where, in equilibrium with measurement back-action heating, it achieves a steady-state temperature, indicated by an asymmetry between the Stokes and anti-Stokes scattering rates. For sufficiently large Larmor frequency, such feedback stabilizes the spin ensemble in a nearly pure quantum state, in spite of continuous measurement by the cavity field.

description: We study the Bose-Einstein condensation of a finite size pion gas subject to the influence of a magnetic field. We find the expressions for the critical chemical potential and temperature for the onset of condensation. We show that for values of the external magnetic flux larger than the elemental flux, the critical temperature is larger than the one obtained by considering only finite size effects. We use experimentally reported values of pion source sizes and multiplicities at LHC energies to show that if the magnetic flux, produced initially in peripheral heavy-ion collision, is at least partially preserved up to the hadronic phase, the combined finite size and magnetic field effects give rise to a critical temperature above the kinetic freeze-out temperature. We discuss the implications for the evolution of the pion system created in relativistic heavy-ion collisions.

description: In 1969 Leighton developed a quasi-1D mathematical model of the solar dynamo, building upon the phenomenological scenario of Babcock(1961). Here we present a modification and extension of Leighton's model. Using the axisymmetric component of the magnetic field, we consider the radial field component at the solar surface and the radially integrated toroidal magnetic flux in the convection zone, both as functions of latitude. No assumptions are made with regard to the radial location of the toroidal flux. The model includes the effects of turbulent diffusion at the surface and in the convection zone, poleward meridional flow at the surface and an equatorward return flow affecting the toroidal flux, latitudinal differential rotation and the near-surface layer of radial rotational shear, downward convective pumping of magnetic flux in the shear layer, and flux emergence in the form of tilted bipolar magnetic regions. While the parameters relevant for the transport of the surface field are taken from observations, the model condenses the unknown properties of magnetic field and flow in the convection zone into a few free parameters (turbulent diffusivity, effective return flow, amplitude of the source term, and a parameter describing the effective radial shear). Comparison with the results of two-dimensional flux transport dynamo codes shows that the model captures the essential features of these simulations. We carry out a parameter study over the four-dimensional parameter space and identify the parameter ranges that provide solar-like solutions. Dipole parity is always preferred and solutions with periods around 22 years and a correct phase difference between flux emergence in low latitudes and the strength of the polar fields are found for a return flow speed around 2~m/s, turbulent diffusivity <80~km^2/s, and dynamo excitation not too far above the threshold (linear growth rate <0.1/yr).

description: Cold atomic ensembles and spinor Bose-Einstein condensates (BECs) are potential candidates for quantum memories as they have long coherence times and can be coherently controlled. Unlike most candidates for quantum memories which are genuine or effective single particle systems, in atomic ensembles the quantum information is stored as a spin coherent state involving a very large number of atoms. A typical task with such ensembles is to drive the state towards a particular quantum state. While such quantum control methods are well-developed for qubit systems, it is a non-trivial task to extend quantum control methods to the many-particle case. The objective of this work is to deterministically steer an arbitrary state of the atomic ensemble into a desired spin coherent state. To this end, we design our control law using stochastic stability theory, the quantum filtering theorem, and phase contrast imaging. We apply our control laws to different axes and show that it is possible to manipulate the atoms into different target states.

Haldane linearisation done right: Solving the nonlinear recombination equation the easy way

description: The nonlinear recombination equation from population genetics has a long history and is notoriously difficult to solve, both in continuous and in discrete time. This is particularly so if one aims at full generality, thus also including degenerate parameter cases. Due to recent progress for the continuous time case via the identification of an underlying stochastic fragmentation process, it became clear that a direct general solution at the level of the corresponding ODE itself should also be possible. This paper shows how to do it, and how to extend the approach to the discrete-time case as well.

description: The role of electronic correlation effects for a realistic description of the electronic properties of LaAlO3/SrTiO3 heterostructures as covered by the on-site Coulomb repulsion within the GGA+U approach is investigated. Performing a systematic variation of the values of the Coulomb parameters applied to the Ti 3d and La 4f orbitals we put previous suggestions to include a large value for the La 4f states into perspective. Furthermore, our calculations provide deeper insight into the band gap landscape in the space spanned by these Coulomb parameters and the resulting complex interference effects. In addition, we identify important correlations between the local Coulomb interaction within the La 4f shell, the band gap, and the atomic displacements at the interface. In particular, these on-site Coulomb interactions influence buckling within the LaO interface layer, which via its strong coupling to the electrostatic potential in the LAO overlayer causes considerable shifts of the electronic states at the surface and eventually controls the band gap.

description: A nonzero electric dipole moment (EDM) of the neutron, proton, deuteron or helion, in fact, of any finite system necessarily involves the breaking of a symmetry, either by the presence of external fields (i.e. electric fields leading to the case of induced EDMs) or explicitly by the breaking of the discrete parity and time-reflection symmetries in the case of permanent EDMs. We discuss two theorems describing these phenomena and report about the cosmological motivation for an existence of CP breaking beyond what is generated by the Kobayashi-Maskawa mechanism in the Standard Model and what this might imply for the permanent electric dipole moments of the nucleon and light nuclei by estimating a window of opportunity for physics beyond what is currently known. Recent - and in the case of the deuteron even unpublished - results for the relevant matrix elements of nuclear EDM operators are presented and the relevance for disentangling underlying New Physics sources are discussed.

description: We extend the continuous-time interaction-expansion quantum Monte Carlo method with respect to measuring observables for fermion-boson lattice models. Using generating functionals, we express expectation values involving boson operators, which are not directly accessible because simulations are done in terms of a purely fermionic action, as integrals over fermionic correlation functions. We also demonstrate that certain observables can be inferred directly from the vertex distribution, and present efficient estimators for the total energy and the phonon propagator of the Holstein model. Furthermore, we generalize the covariance estimator of the fidelity susceptibility, an unbiased diagnostic for phase transitions, to the case of retarded interactions. The new estimators are applied to half-filled spinless and spinful Holstein models in one dimension. The observed renormalization of the phonon mode across the Peierls transition in the spinless model suggests a soft-mode transition in the adiabatic regime. The critical point is associated with a minimum in the phonon kinetic energy and a maximum in the fidelity susceptibility.

description: We investigate the dependence of nonabelian T-duality on various identification of the group of target space isometries of nonlinear sigma models with its orbits, i.e. with respect to the location of the group unit on manifolds invariant under the isometry group. We show that T-duals constructed by isometry groups of dimension less than the dimension of the (pseudo)riemannian manifold may depend not only on the initial metric but also on the choice of manifolds defining positions of group units on each of the submanifold invariant under the isometry group. We investigate whether this dependence can be compensated by coordinate transformation.
