Critical Metallicity and Fine-Structure Emission of Primordial Gas Enriched by the First Stars

description: The influence of the first stars on the formation of second-generation objects at high redshift may be determined, in part, by their metal enrichment of surrounding gas. At a critical metallicity, Zcrit, primordial gas cools more efficiently by fine-structure lines of CII (157.74 um), OI (63.18 um, 145.5 um), SiII (34.8 um), and FeII (25.99 um, 35.35 um) than by HI or H2 emission. This cooling may alter the process of fragmentation into smaller units. We study the time-dependent cooling of primordial gas enriched by heavy elements from early massive stars, particularly O, Si, and Fe. We define Zcrit as the point when the total cooling rate by metals plus H2 equals the adiabatic compressional heating. We explore two metallicity scenarios: (1) a single metallicity for all heavy elements; (2) individual metallicities (Z_C, Z_O, Z_Si, Z_Fe) from theoretical supernova yields. For dense gas [n > 10^3 cm^(-3)] with metals in relative solar abundances, fragmentation occurs at Zcrit ~ 10^(-3.5) Z_sun. However, for lower density gas, [n = 1-100 cm^(-3)], particularly in halos enriched in Si, O, and Fe, we find Zcrit = 0.1-1% Zsun. The critical metallicity approaches a minimum value at high-n set by efficient LTE cooling, with thermalized level populations of fine-structure states and H2 rotational states (J = 2 and J = 3). Primordial clouds of 10^8 Msun at 200K are detectable in redshifted fine-structure lines, with far-infrared fluxes between 10^-22 and 10^-21 W/m^2. For metallicities Z_O = 10^(-3) and molecular fractions f(H2) = 10^(-3) the fine-structure emission lines of OI, SiII, and FeII could be 10^2 - 10^3 times stronger than the H2 rotational lines at 28.22 um (J = 2-0) and 17.03 um (J = 3-1).

Dispersion cancellation in a quantum interferometer with independent single photons

description: A key technique to perform a proper quantum information processing is to get a high visibility quantum interference between independent single photons. One of the crucial elements that affects the quantum interference is a group velocity dispersion that occurs when the single photons pass through a dispersive medium. We theoretically and experimentally demonstrate that an effect of group velocity dispersion on the two-photon interference can be cancelled if two independent single photons experience the same amount of pulse broadening. This dispersion cancellation effect can be generalized to a multi-path linear interferometer with multiple independent single photons. As multi-path quantum interferometers are at the heart of quantum communication, photonic quantum computing, and boson sampling applications, our work should find wide applicability in quantum information science.

A total of 86 onchocercid specimens (48 sequences from this study with 38 sequences from 38 species from Lefoulon et al. [2]) were analysed. Filaria latala was used as the outgroup. The topology was inferred using Maximum Likelihood, under the general time reversible model, including invariant sites and gamma distribution (GTR+I+Γ). Nodes are associated with bootstrap values based on 1000 replicates. The onchocercid subfamilies are indicated by color: blue for Onchocercinae, dark green for Dirofilariinae, purple for Splendidofilariinae, yellow for Waltonellinae. Although the cox1 gene is not informative enough for deeper phylogenies it is for species level phylogenies and onchocercid clades described in Lefoulon et al. [2] are identifiable, especially ONC5 to which belong the new sequences.

description: This paper analyses the economics of biofuel production and the implications that the accelerating growth in biofuel production in many countries could have on agricultural markets. It shows that production costs of ethanol and biodiesel differ significantly across countries and feedstock crops. These costs often exceed those of fossil fuels. In consequence, the economics of biofuel production depends on public support in most countries. Similarly, land requirements for crops required to enable significant shares of biofuel production in transport fuel consumption are shown to be substantial in many countries given current technologies. An expected growth in biofuel production is, therefore, likely to have a significant increasing impact on world prices for sugar, cereals and oilseeds beyond what is caused by higher crude oil prices alone. The paper points out a number of policy issues that require attention and further analysis to facilitate a fuller discussion of biofuel policies.

description: Smart home devices have brought us many benefits such as advanced security, convenience, and entertainment. However, these devices also have made unintended consequences like giving ultimate power for devices' owners over their intimate partners in the same household which might lead to tech-facilitated domestic abuse (tech-abuse) as recent research has shown. In this paper, we systematize findings on tech-abuse in smart homes. We show that domestic abuse and Intimate Partner Violence (IPV) in smart homes is more effective and less risky for abusers. Victims find it more harmful and more challenging to protect themselves from. We articulate a comprehensive analysis of all the phases of abuse in smart homes and categorize risks and needs in each phase. Technical analysis of current smart home technologies is conducted to shed light upon their limitations. We also summarize recent recommendations to combat tech-abuse in smart homes and focus on their potentials and shortcomings. Unsurprisingly, we find that many recommendations conflict with each other due to a lack of understanding of phases of abuse in smart homes. Desirable properties to design abuse-resistant smart home devices are proposed for all the phases of abuse. The research community benefits from our analysis and recommendations to move forward with a focus on filling the blind spots of existing smart home devices' safety measures and building appropriate safety measures that consider tech-abuse threats in smart homes.

description: The results of a current study point out the macroeconomic effects associated with the use and production of renewable resources (NAWARO) in Germany. It focuses on the direct and indirect employment effects in the NAWARO market segments biofuels, energy/electricity, chemical commodities and materials. Supply quantities of renewable resources and agricultural area in Germany required by the industrial production in the different market segments and associated employment effects in the German agricultural sector are also analyzed. Above all, if Germany succeeds to be a lead market in certain NAWARO market segments while retaining agricultural and industrial value chains in Germany considerable employment potentials emerge.

description: A Fourier-based Library of Unbounded Poisson Solvers (FLUPS) for 2D and 3D homogeneous distributed grids is presented. It is designed to handle every possible combination of periodic, symmetric, semi-unbounded and fully unbounded boundary conditions for the Poisson equation on rectangular domains with uniform resolution. FLUPS leverages a dedicated implementation of 3D Fourier transforms to solve the Poisson equation using Green's functions, in a fast and memory-efficient way. Several Green's functions are available, optionally with explicit regularization, spectral truncation, or using lattice Green's functions, and provide verified convergence orders from 2 to spectral-like. The algorithm depends on the FFTW library to perform 1D transforms, while Message Passing Interface (MPI) communications enable the required remapping of data in memory. For the latter operation, a first available implementation resorts to the standard all-to-all routines. A second implementation, featuring non-blocking and persistent point-to-point communications, is however shown to be more efficient in a majority of cases and especially while taking advantage of the shared memory parallelism with OpenMP. The scalability of the algorithm, aimed at massively parallel architectures, is demonstrated up to 73 720 cores. The results obtained with three different supercomputers show that the weak efficiency remains above 40\% and the strong efficiency above 30% when the number of cores is multiplied by 16, for typical problems. These figures are slightly better than those expected from a third party 3D Fast Fourier Transform (FFT) tool, with which a 20% longer execution time was also measured on average.

description: In this article the profitability of the bioethanol production in Germany is analysed under consideration of the international competition. Therefore, the production costs of bioethanol from wheat and beet in Germany as well as from sugar cane and corn in other representative countries are compared. Based on this, the competitiveness of imported as well as domestic bioethanol against gasoline on the German market are analyzed and the maximum payable feedstock price for sugar beet is calculated. The calculations lead to the result, that, despite the implemented mandatory blending, further cost reductions for the production of bioethanol in Germany are required in order to achieve competitiveness against imports, whereas the utilization of bioethanol is independent of the crude oil price within the targets of the mandatory blending scheme.

description: I propose that self-duality in quantum phase-space provides the criteria for the selection of the quantum gravity vacuum. The evidence for this assertion arises from two independent considerations. The first is the phenomenological success of the free fermionic heterotic-string models, which are constructed in the vicinity of the self-dual point under T-duality. The relation between the free fermionic models and the underlying Z2 X Z2 toroidal orbifolds is discussed. Recent analysis revealed that the Z2 X Z2 free fermionic orbifolds utilize an asymmetric shift in the reduction to three generations, which indicates that the untwisted geometrical moduli are fixed near the self-dual point. The second consideration arises from the recent formulation of quantum mechanics from an equivalence postulate and its relation to phase-space duality. In this context it is demonstrated that the trivial state, with V(q)=E=0, is identified with the self-dual state under phase-space duality. These observations suggest a more general mathematical principle in operation. In physical systems that exhibit a duality structure, the self-dual states under the given duality transformations correspond to critical points.

description: Accurate rotation estimation is at the heart of robot perception tasks such as visual odometry and object pose estimation. Deep neural networks have provided a new way to perform these tasks, and the choice of rotation representation is an important part of network design. In this work, we present a novel symmetric matrix representation of the 3D rotation group, SO(3), with two important properties that make it particularly suitable for learned models: (1) it satisfies a smoothness property that improves convergence and generalization when regressing large rotation targets, and (2) it encodes a symmetric Bingham belief over the space of unit quaternions, permitting the training of uncertainty-aware models. We empirically validate the benefits of our formulation by training deep neural rotation regressors on two data modalities. First, we use synthetic point-cloud data to show that our representation leads to superior predictive accuracy over existing representations for arbitrary rotation targets. Second, we use image data collected onboard ground and aerial vehicles to demonstrate that our representation is amenable to an effective out-of-distribution (OOD) rejection technique that significantly improves the robustness of rotation estimates to unseen environmental effects and corrupted input images, without requiring the use of an explicit likelihood loss, stochastic sampling, or an auxiliary classifier. This capability is key for safety-critical applications where detecting novel inputs can prevent catastrophic failure of learned models.

description: In the outskirts of the intracluster medium (ICM) in galaxy clusters, the temperature decreases with radius. Due to the weakly collisional nature of the plasma, these regions are susceptible to the magneto-thermal instability (MTI), which can sustain turbulence and provide turbulent pressure support in the ICM. This instability arises due to heat conduction directed along the magnetic field, with a heat conductivity which is normally assumed to be given by the Spitzer value. Recent numerical studies of the ion mirror and the electron whistler instability using particle-in-cell codes have shown that microscale instabilities can lead to a reduced value for the heat conductivity in the ICM. This could in turn influence the efficiency with which the MTI drives turbulence. In this paper we investigate the influence of reduced heat transport on the nonlinear evolution of the MTI. We study plane-parallel, initially static atmospheres and employ a subgrid model that mimics the influence of the mirror instability on the heat conductivity. We use this subgrid model to assess the effect of microscales on the large scale dynamics of the ICM. We find that the nonlinear saturation of the MTI is surprisingly robust in our simulations. Over a factor of $\sim 10^3$ in the thermal-to-magnetic pressure ratio and collisionality we find at most modest changes to the saturation of the MTI with respect to reference simulations where heat transport is unsuppressed.

description: The production potential for bio-energy sources of the EU agriculture is quantified. In doing so, set-aside land and rededication of land for other purposes are considered. Furthermore, the simplifying hypothetical assumption is made that on the one hand in the case of subsidized surplus production beyond food self-sufficiency could be used as technical potential for the production of energy plants and on the other hand in deficit situations for typical agricultural products in the EU as e.g. grain crops, rape seed, sunflowers the production of food would have priority. On the base of these assumptions the changes in the food consumption as well as increasing yield and efficiency in agricultural production are balanced. The estimates of the potential result for Germany in 2020 at up to 7 mill. hectares agricultural land and for the EU-27 depending on the policy scenario adopted between 19 and 51 mill. hectares.

description: We suggest that the decay modes of kaons with a pion and a pionium ($π^+π^-$ atom) in the final state can constitute a not yet considered background to the very rare decay $K\toπν\barν$. In fact, a part of pioniums may escape the decay region before decaying into two $π^0$s (or to $π^0π^0γ$ in the case of excited pionium). To illustrate the importance of this background, we show that it may even explain, under some assumptions, the unexpected $K_L$ decay events that appeared in the KOTO experiment.

description: The amendment of the Renewable Energy Sources Act (EEG) in 2004 has established an attractive support of using renewable resources for energy production, which since then has fuelled a rapid expansion of the competitive cropping of energy maize. The regionalised agricultural sector model RAUMIS was applied to calculate expected energy maize production as well as impacts on agricultural land use, production and income. Accordingly, the energy maize acreage rises up to about 1.8 mill hectares in the long run leading to substantial land use changes. The produced energy maize for biogas and power generation respectively is sufficient to provide circa 9% of the current German total electricity generation. In regard to the costs for the current consumer which amount to 4.4 bn € per year compared to electricity on the basis of fossil resources as well as the long term commitment to this specific power generation technology it is strongly recommended to review the measures set out in the EEG with respect to its efficiency to achieve the pursued objectives.

description: We perform a joint BAO and RSD analysis using the eBOSS DR16 LRG and ELG samples in the redshift range of $z\in[0.6,1.1]$, and detect a RSD signal from the cross power spectrum at a $\sim4σ$ confidence level, i.e., $fσ_8=0.317\pm0.080$ at $z_{\rm eff}=0.77$. Based on the chained power spectrum, which is a new development in this work to mitigate the angular systematics, we measurement the BAO distances and growth rate simultaneously at two effective redshifts, namely, $D_{\rm M}/r_{\rm d} \ (z=0.70)=17.96\pm0.51, \ D_{\rm H}/r_{\rm d} \ (z=0.70)=21.22\pm1.20, \ fσ_8 \ (z=0.70) =0.43\pm0.05$, and $D_{\rm M}/r_{\rm d} \ (z=0.845)=18.90\pm0.78, \ D_{\rm H}/r_{\rm d} \ (z=0.845)=20.91\pm2.86, \ fσ_8 \ (z=0.845) =0.30\pm0.08$. Combined with BAO measurements including those from the eBOSS DR16 QSO and Lyman-$α$ sample, our measurement has raised the significance level of a nonzero $Ω_{\rm Λ}$ to $\sim11σ$.

description: [Resumen]

Cornelia Hahn Oberlander ha sido una profesional polifacética que ha explorado diferentes caminos para desarrollar la Arquitectura del Paisaje. Uno de ellos ha sido el diseño de los espacios de juego. 

Las influencias del entorno durante su infancia, el continuo contacto con la naturaleza y sus referentes familiares construyen una personalidad fuerte que durante sus estudios en Harvard se empapará y conectará con un pensamiento conceptual y una expresión moderna que reafirmará sus intenciones. 

En estos primeros años, trabajando en comunidad e interviniendo en pequeños parques de barrio, nacen sus hijos y es durante su primera infancia cuando se dedica a construir espacios de juego. 

Este trabajo trata de conectar la infancia de Cornelia con la de sus hijos y con la de los niños que juegan en sus parques, poniendo en valor el espacio de juego como un elemento fundamental para el desarrollo de las ciudades y de la sociedad. 

 

[Abstract]

Cornelia Hahn Oberlander has been a versatile professional who has explored different lines to develop Landscape Architecture. One of them has been the design of the play spaces. 

The infl uences of her atmosphere during her childhood, the continuous contact with nature and her family references build a strong personality that during her studies at Harvard will be soaked and connected with a conceptual thought and a modern expression that will reaffi rm her intentions. 

In these early years, working in community and intervening in small neighborhood playgrounds, her children are born and it is during her early childhood that she dedicates herself to construct play spaces. 

This work tries to connect Cornelia’s childhood with that of her children and with that of the children who play in her playgrounds, valuing the play space as a fundamental element for the development of the cities and the society.

description: We study transport through a one-dimensional quantum wire of correlated fermions connected to semi-infinite leads. The wire contains either a single impurity or two barriers, the latter allowing for resonant tunneling. In the leads the fermions are assumed to be non-interacting. The wire is described by a microscopic lattice model. Using the functional renormalization group we calculate the linear conductance for wires of mesoscopic length and for all relevant temperature scales. For a single impurity, either strong or weak, we find power-law behavior as a function of temperature. In addition, we can describe the complete crossover from the weak- to the strong-impurity limit. For two barriers, depending on the parameters of the enclosed quantum dot, we find temperature regimes in which the conductance follows power-laws with "universal" exponents as well as non-universal behavior. Our approach leads to a comprehensive picture of resonant tunneling. We compare our results with those of alternative approaches.

description: The dramatic rise in world food prices since 2007 has commanded the world’s attention. However, in recent months, world food prices have fallen almost as rapidly as they had risen in late 2007 and early 2008, yet as is demonstrated in this report, domestic food price levels in many eastern and southern African markets are not closely tracking world prices. Fertilizer prices remain at unprecedentedly high levels and may have a critical influence on future food production levels in the region. Against this backdrop, there is an urgent need for information about how the current food situation is unfolding in the region, the immediate policy response options, and the longer-term challenges and opportunities. This study has three objectives: 1) to examine the impact of recent world food price changes on domestic maize and fertilizer prices in the region; 2) to assess possible changes in cropping patterns, national food production, and consumers’ access to food in light of these price movements; and 3) to consider the implications for policy and program response by governments, donors, and the private sector.
Bootstrap resampling as a tool for radio-interferometric imaging fidelity assessment

description: We report on a numerical evaluation of the statistical bootstrap as a technique for radio-interferometric imaging fidelity assessment. The development of a fidelity assessment technique is an important scientific prerequisite for automated pipeline reduction of data from modern radio interferometers. We evaluate the statistical performance of two bootstrap methods, the model-based bootstrap and subsample bootstrap, against a Monte Carlo parametric simulation, using interferometric polarization calibration and imaging as the representative problem under study. We find both statistical resampling techniques to be viable approaches to radio-interferometric imaging fidelity assessment which merit further investigation. We also report on the development and implementation of a new self-calibration algorithm for radio-interferometric polarimetry which makes no approximations for the polarization source model.

description: This working paper synthesizes the theoretical and empirical literature on the use of cash transfers in response to food crisis situations, with particular attention to their use in situations that are exacerbated by volatile, often inflationary, commodity prices. The paper is designed for policymakers who are wondering if cash transfers might be an appropriate instrument in the context of 2008’s unstable commodity prices for both food and energy, but are unfamiliar with the literature and discussions surrounding the cash vs. food debate. After defining some key terms and presenting a brief review of the theory behind cash transfer use, the paper synthesizes evidence from studies that have evaluated past cash transfer programs. While the focus is on examples from Sub-Saharan Africa (primarily Malawi, Mozambique, Zambia, Kenya), there are also valuable lessons incorporated from other regions of the world.

description: The accelerated digitalisation of society along with technological evolution have extended the geographical span of cyber-physical systems. Two main threats have made the reliable and real-time control of these systems challenging: (i) uncertainty in the communication infrastructure induced by scale, and heterogeneity of the environment and devices; and (ii) targeted attacks maliciously worsening the impact of the above-mentioned communication uncertainties, disrupting the correctness of real-time applications. This paper addresses those challenges by showing how to build distributed protocols that provide both real-time with practical performance, and scalability in the presence of network faults and attacks, in probabilistic synchronous environments. We provide a suite of real-time Byzantine protocols, which we prove correct, starting from a reliable broadcast protocol, called PISTIS, up to atomic broadcast and consensus. This suite simplifies the construction of powerful distributed and decentralized monitoring and control applications, including state-machine replication. Extensive empirical simulations showcase PISTIS's robustness, latency, and scalability. For example, PISTIS can withstand message loss (and delay) rates up to 50% in systems with 49 nodes and provides bounded delivery latencies in the order of a few milliseconds.

description: We describe a method to estimate the mass distribution of a gravitational lens and the position of the sources from combined strong and weak lensing data. The algorithm combines weak and strong lensing data in a unified way producing a solution which is valid in both the weak and strong lensing regimes. We study how the result depends on the relative weighting of the weak and strong lensing data and on choice of basis to represent the mass distribution. We find that combining weak and strong lensing information has two major advantages: it eliminates the need for priors and/or regularization schemes for the intrinsic size of the background galaxies (this assumption was needed in previous strong lensing algorithms) and it corrects for biases in the recovered mass in the outer regions where the strong lensing data is less sensitive. The code is implemented into a software package called WSLAP (Weak & Strong Lensing Analysis Package) which is publicly available at http://darwin.cfa.harvard.edu/SLAP/

Xenon-copper chemical bonding : Fourier transform microwave spectroscopy of XeCuX (X = F, C1)
Creators: name: Michaud, Julie M.
Publisher: name: University of British Columbia
Year: 2009

description: The rotational spectra of seven isotopomers of XeCuF and eight isotopomers of XeCuCl have been measured in the range of 7-22 GHz using a pulsed jet cavity Fourier transform microwave spectrometer. The molecules were prepared by laser ablation of a Cu metal rod with a pulsed Nd:YAG laser at 1064 nm and allowing the plasma to react with appropriate precursors (Xe and SF6 or CI2) entrained in a carrier gas of Ar. Rotational constants, centrifugal distortion constants, internuclear distances, vibration frequencies, and Xe, Cu and CI hyperfme coupling constants have been evaluated. The Xe-Cu bonds are short and the molecules are rigid. The 1 3 1Xe nuclear quadrupole coupling constants in both XeCuF and XeCuCl are large (-87.8 and -81.4 MHz, respectively). The Cu nuclear quadrupole coupling constants differ radically from those of uncomplexed CuF and CuCl molecules. Ab initio calculations have supported the experimental results with short NgM bonds and rigid molecules. Mulliken populations and MOLDEN plots have also been calculated and both are consistent with strong interactions between the noble gas and the noble metal. The local energy densities were calculated to be negative and indicate the presence of a covalent XeCu bond. Both experimental and theoretical results are consistent with those reported earlier for other noble gas - noble metal halide molecules. The evidence is convincing for chemical bonding present between the noble gas and the noble metal in all NgMX molecules.
