description: Regional studies on the origin and fate of organic carbon (OC) in marine sediments are scarce due to limited spatial data coverage and the complex interplay among biological, physicochemical, and geological processes that can influence OC content and geochemical signatures on different spatial scales. Yet, such studies are vital to constrain global carbon inventories for ocean sediments.

To shed light on the controls on the origin, distribution, and fate of sedimentary OC in continental margins and adjacent deep-sea basins, we investigate the geochemical and sedimentological characteristics of organic matter (OM) in the semi-enclosed Western Mediterranean Sea. Here, we analyze 149 core-top samples from the Western Mediterranean Sea and the adjacent Atlantic Ocean sector and explore the spatial distribution of OC content, OC-ẟ13C, OC-Δ14C, C/N, grain size, and mineral surface area, among others.

Most geochemical parameters depict a clear SW-NE gradient between the westernmost and the easternmost basins. This gradient reverses in the Gulf of Lions (NW Mediterranean). Thus, OC is younger and of primarily marine origin in samples from the Atlantic sector and the Alboran Sea (SW Mediterranean). In the Algerian Basin, the Balearic Sea, and the Algero-Provencal Basin the influence of terrestrial OC input increases towards the NE characterized by the presence of highly 13C- and 14C-depleted (aged) sedimentary OC. Finally, samples from the Gulf of Lions show a larger influence of fresh and young OC compared to other northeastern basins.

The interplay between marine primary productivity and delivery of terrestrial OC is the main factor that determines the observed gradient. Primary productivity decreases from the southwestern basins towards the NE and increases again northeasternmost basin, the Gulf of Lions. By contrast, the terrestrial OC carbon delivered by rivers and channeled to the deeper basin by canyons has an increasing influence on sedimentary OC toward the NE.

When explored from a sedimentological context, our results reveal that lateral transport of OC and OM protection by mineral surfaces potentially act as secondary controls on the OC fate in surface sediments of the Western Mediterranean Sea.

This integrated study contributes to a better knowledge of the interplay of biological, chemical, and hydrological factors that influence the amount and geochemical characteristics of sedimentary OC in the land-sea continuum and the deeper ocean, a fundamental consideration to constraining global carbon inventories.

description: The Parker Solar Probe was launched on 2018 August 12 and completed its second orbit on 2019 June 19 with perihelion of 35.7 solar radii. During this time, the Energetic particle Instrument-Hi (EPI-Hi, one of the two energetic particle instruments comprising the Integrated Science Investigation of the Sun, ISOIS) measured seven proton intensity increases associated with stream interaction regions (SIRs), two of which appear to be occurring in the same region corotating with the Sun. The events are relatively weak, with observed proton spectra extending to only a few MeV and lasting for a few days. The proton spectra are best characterized by power laws with indices ranging from -4.3 to -6.5, generally softer than events associated with SIRs observed at 1 au and beyond. Helium spectra were also obtained with similar indices, allowing He/H abundance ratios to be calculated for each event. We find values of 0.016-0.031, which are consistent with ratios obtained previously for corotating interaction region events with fast solar wind < 600 km s-1. Using the observed solar wind data combined with solar wind simulations, we study the solar wind structures associated with these events and identify additional spacecraft near 1 au appropriately positioned to observe the same structures after some corotation. Examination of the energetic particle observations from these spacecraft yields two events that may correspond to the energetic particle increases seen by EPI-Hi earlier.

description: Managing the forested landscape in Malaysia and Indonesia for timber extraction while also conserving the endangered orangutan that inhabit some of the remaining forests in this region is a challenge. Heavy logging is a common feature of the Indonesian and Malaysian timber industries. It is profitable but detrimental to the survival of this primate species. A type of logging which appears to be compatible with maintaining orangutans in the forested landscape is light logging. It involves extracting fewer logs and ensures that the logged area is minimally damaged. However, switching to a light logging regime involves a financial opportunity cost, a cost which is an obstacle to the widespread adoption of this type of logging by businesses and the state. This paper reviews the case study of a unique light logging experiment conducted in the Deramakot Forest Reserve, in one of the orangutan’s strongholds, the Malaysian state of Sabah. The Deramakot experiment claims to generate revenue from low-impact logging while also sustaining its population of orangutans. Here, we survey the importance of the timber industry to Sabah, the profitability of the Deramakot scheme, the orangutan conservation aspect of this scheme, and the influence of the politico-bureaucratic factor or public economics on sustaining the domestic light-logging agenda. Then, this paper attempts to answer the question of whether economic returns could be balanced with orangutan conservation given the light and heavy logging regimes, bearing in mind the opportunity costs associated with these. More specifically, using the data that has been made available from the Deramakot case study, this paper employs a mathematical model to analyse whether the foregone profits of pursuing light logging is higher than setting aside strict protected areas while more intense logging the remaining forests, subject to the goal of maintaining a desired orangutan population size. The results reveal that, under certain conditions, the option of conserving the orangutan under mainly light logging is economically more attractive for a scenario involving Sabahan forests than the option of strictly protecting orangutan habitats and heavily logging the forests without significant orangutan populations. This finding contributes to the question asked by conservationists of how forests should be partitioned to satisfy both economic and conservation needs.

description: Each year, rivers export more than one teragram of carbon out of Switzerland as dissolved inorganic carbon (DIC), integrating diverse atmospheric, terrestrial, and aquatic carbon sources over their catchments. However, the contributions of the different carbon sources to riverine DIC – and thus the implications of DIC dynamics for the global carbon balance and climate – remain uncertain. Building upon the 50-year dataset from the national long-term river monitoring network of Switzerland (NADUF), we attempt to predict the vertical CO2 fluxes between rivers and the atmosphere, and to quantify catchment-scale DIC production through rock weathering, leaching of soil-respired CO2, and mineralization of organic carbon during fluvial transport. Supported by the national network of groundwater monitoring sites (NAQUA) and soil sampling sites covering Switzerland, a Bayesian mixing model disentangles the sources of riverine DIC using measured data of carbon and water isotopes (14C, 13C, 2H, 18O), as well as ion concentrations. The exchanges between river DIC and atmospheric CO2 across the air–water interface are predicted with a diffusion model, validated with measurements of the CO2 flux and isotopes from in situ floating-chamber experiments. Our predictions of the DIC source contributions and the net CO2 flux from rivers help to elucidate the role of DIC in the carbon balance of alpine and perialpine river catchments, and contribute towards closing the national carbon budget of Switzerland.

The Financial and Political Opportunity Costs of Orangutan Conservation in the Face of Oil-Palm Expansion

description: This paper examines the opportunity costs of conserving the forest habitats of the endangered orangutan (Pongo pygmaeus spp.) of Indonesia and Malaysia in the face of a highly profitable alternative land use, the conversion of these habitats for the production of palm oil. It shows that one component of the financial opportunity cost of conserving orangutan habitat, the business opportunity cost (profits foregone), was high in both Malaysia and Indonesia in the case of oil-palm development. It is argued that this would be difficult to offset under the payments-for-ecosystem-services (PES) approach. However, the government opportunity cost of conservation in Indonesia, such as the land-tax revenue foregone by local governments by conserving rather than leasing out orangutan habitats for agricultural use, are sometimes lower than the business opportunity cost of conservation. It is suggested that targeting government opportunity costs to conserve unleased forests could potentially offer lower-cost opportunities for conserving orangutan habitats. If, however, political and institutional realities are taken into account, there might exist another type of opportunity cost of conservation— a political one— that could impede the success of the PES approach. Some oil-palm companies in Borneo offer financial inducements in the form of kickbacks and other types of political donations to government officials to obtain land for growing oil palm. This ‘government decisionmaker’s opportunity cost’ has not been addressed in the PES literature, which typically compares potential ecosystem payments with the commercial profits that would have to be sacrificed as a result of conserving forests. The impact of this political opportunity cost on oil-palm expansion is discussed. It is suggested that solutions to this conservation problem cannot be restricted to the monetary valuation method but must also involve alternative political economic interventions.

description: In this paper is presented an abstract theory of quantum processors and controllers, special kind of quantum computational network defined on a composite quantum system with two parts: the controlling and controlled subsystems. Such approach formally differs from consideration of quantum control as some external influence on a system using some set of Hamiltonians or quantum gates. The model of programmed quantum controllers discussed in present paper is based on theory of universal deterministic quantum processors (programmable gate arrays). Such quantum devices may simulate arbitrary evolution of quantum system and so demonstrate an example of universal quantum control. Keywords: Quantum, Computer, Control, Processor, Universal

description: Light experiences a non-uniformly moving medium as an effective gravitational field, endowed with an effective metric tensor $\tilde{g}^{μν}=η^{μν}+(n^2-1)u^μu^ν$, $n$ being the refractive index and $u^μ$ the four-velocity of the medium. Leonhardt and Piwnicki [Phys. Rev. A {\bf 60}, 4301 (1999)] argued that a flowing dielectric fluid of this kind can be used to generate an 'optical black hole'. In the Leonhardt-Piwnicki model, only a vortex flow was considered. It was later pointed out by Visser [Phys. Rev. Lett. {\bf 85}, 5252 (2000)] that in order to form a proper optical black hole containing an event horizon, it becomes necessary to add an inward radial velocity component to the vortex flow. In the present paper we undertake this task: we consider a full spiral flow, consisting of a vortex component plus a radially infalling component. Light propagates in such a dielectric medium in a way similar to that occurring around a rotating black hole. We calculate, and show graphically, the effective potential versus the radial distance from the vortex singularity, and show that the spiral flow can always capture light in both a positive, and a negative, inverse impact parameter interval. The existence of a genuine event horizon is found to depend on the strength of the radial flow, relative to the strength of the azimuthal flow. A limitation of our fluid model is that it is nondispersive.

description: We consider the time evolution of the radiation field (R) and a two-level atom (A) in a resonant microcavity in terms of the Jaynes-Cummings model with an initial general pure quantum state for the radiation field. It is then shown, using the Cauchy-Schwarz inequality and also a Poisson resummation technique, that {\it perfect} coherence of the atom can in general never be achieved. The atom and the radiation field are, however, to a good approximation in a pure state $|ψ>_A\otimes|ψ>_R$ in the middle of what has been traditionally called the ``collapse region'', independent of the initial state of the atoms, provided that the initial pure state of the radiation field has a photon number probability distribution which is sufficiently peaked and phase differences that do not vary significantly around this peak. An approximative analytic expression for the quantity $\Tr[ρ^2_{A}(t)]$, where $ρ_{A}(t)$ is the reduced density matrix for the atom, is derived. We also show that under quite general circumstances an initial entangled pure state will be disentangled to the pure state $|ψ>_{A\otimes R}$.

description: In this paper we consider periodic orbits of planar linear Filippov systems with a line of discontinuity. Unlike many publications researching only the maximum number of crossing periodic orbits, we investigate not only the number and configuration of sliding periodic orbits, but also the coexistence of sliding periodic orbits and crossing ones. Firstly, we prove that the number of sliding periodic orbits is at most 2, and give all possible configurations of one or two sliding periodic orbits. Secondly, we prove that two sliding periodic orbits coexist with at most one crossing periodic orbit, and one sliding periodic orbit can coexist with two crossing ones.

description: Surface wave tomography uses measured dispersion properties of surface waves to infer the spatial distribution of subsurface properties such as shear-wave velocities. These properties can be estimated vertically below any geographical location at which surface wave dispersion data are available. As the inversion is significantly non-linear, Monte Carlo methods are often used to invert dispersion curves for shear-wave velocity profiles with depth to give a probabilistic solution. Such methods provide uncertainty information but are computationally expensive. Neural network based inversion provides a more efficient way to obtain probabilistic solutions when those solutions are required beneath many geographical locations. Unlike Monte Carlo methods, once a network has been trained it can be applied rapidly to perform any number of inversions. We train a class of neural networks called mixture density networks, to invert dispersion curves for shear-wave velocity models and their non-linearised uncertainty. Mixture density networks are able to produce fully probabilistic solutions in the form of weighted sums of multivariate analytic kernels such as Gaussians, and we show that including data uncertainties in the mixture density network gives more reliable mean velocity estimates when data contains significant noise. The networks were applied to data from the Grane field in the Norwegian North sea to produce shear-wave velocity maps at several depth levels. Post-training we obtained probabilistic velocity profiles with depth beneath 26,772 locations to produce a 3D velocity model in 21 seconds on a standard desktop computer. This method is therefore ideally suited for rapid, repeated 3D subsurface imaging and monitoring.

Algebraic Rainich theory and antisymmetrisation in higher dimensions

description: The classical Rainich(-Misner-Wheeler) theory gives necessary and sufficient conditions on an energy-momentum tensor $T$ to be that of a Maxwell field (a 2-form) in four dimensions. Via Einstein's equations these conditions can be expressed in terms of the Ricci tensor, thus providing conditions on a spacetime geometry for it to be an Einstein-Maxwell spacetime. One of the conditions is that $T^2$ is proportional to the metric, and it has previously been shown in arbitrary dimension that any tensor satisfying this condition is a superenergy tensor of a simple $p$-form. Here we examine algebraic Rainich conditions for general $p$-forms in higher dimensions and their relations to identities by antisymmetrisation. Using antisymmetrisation techniques we find new identities for superenergy tensors of these general (non-simple) forms, and we also prove in some cases the converse; that the identities are sufficient to determine the form. As an example we obtain the complete generalisation of the classical Rainich theory to five dimensions.

description: We study the chemical evolution of Zr, La, Ce and Eu in the Milky Way discs and bulge by means of chemical evolution models compared with recent spectroscopic data. We consider detailed chemical evolution models for the Galactic thick disc, thin disc and bulge, which have been already tested to reproduce the observed [$α$/Fe] vs [Fe/H] diagrams and metallicity distribution functions for the three different components, and we apply them to follow the evolution of neutron capture elements. In the [Eu/Fe] vs [Fe/H] diagram, we observe and predict three distinct sequences corresponding to the thick disc, thin disc and bulge, similarly to what happens for the $α$-elements. We can nicely reproduce the three sequences by assuming different timescales of formation and star formation efficiencies for the three different components, with the thin disc forming on a longer timescale of formation with respect to the thick disc and bulge. On the other hand, in the [X/Fe] vs [Fe/H] diagrams for Zr, La and Ce, the three populations are mixed and also from the model point of view there is an overlapping between the predictions for the different Galactic components, but the observed behaviour can be also reproduced by assuming different star formation histories in the three components. In conclusions, it is straightforward to see how different star formation histories can lead to different abundance patterns and also looking at the abundance patterns of neutron capture elements can help in constraining the history of formation and evolution of the major Galactic components.

description: We experimentally investigate the influence of the orientation of optically pumped magnetometers in Earth's magnetic field. We focus our analysis to an operational mode that promises femtotesla field resolu-tions at such field strengths. For this so-called light-shift dispersed Mz(LSD-Mz) regime, we focus on the key parameters defining its performance. That are the reconstructed Larmor frequency, the transfer function between output signal and magnetic field amplitude as well as the shot noise limited field resolution. We demonstrate that due to the use of two well balanced laser beams for optical pumping with different helicities the heading error as well as the field sensitivity of a detector both are only weakly influenced by the heading in a large orientation angle range.

description: Agricultural policy in the United States over the last fifteen years has increasingly included conservation aspects starting with the Conservation Reserve Program, Conservation Compliance, Swampbuster, and Sodbuster provisions of the 1985 Farm Bill. Another development is that the Soil Conservation Service has been renamed the Natural Resource Conservation Service, reflecting its expanded mandate. While regulation of nonpoint source pollution has been left to state governments, there are recent developments toward bringing agricultural pollution under federal control. In the future we will see a mix of federal and state policies, increasingly relying on regulation and economic incentives as well as new technologies. A policy of phased implementation of policy instruments is proposed.

A rigorous form of the classical connection between gravity in three dimensions and two-dimensional conformal field theory is employed, where the fundamental degrees of freedom are described in terms of two dependent SL(2,C) currents. In contrast to the BTZ case, however, quantization does not give the Bekenstein-Hawking entropy connected to the cosmological horizon of Kerr-de Sitter space.

description: We study collective behavior of locally-coupled limit-cycle oscillators with scattered intrinsic frequencies on $d$-dimensional lattices. A linear analysis shows that the system should be always desynchronized up to $d=4$. On the other hand, numerical investigation for $d= 5$ and 6 reveals the emergence of the synchronized (ordered) phase via a continuous transition from the fully random desynchronized phase. This demonstrates that the lower critical dimension for the phase synchronization in this system is $d_{l}=4$

The THz emission can be either enhanced or suppressed, or even the polarity can be reversed, by introducing a magnetization gradient in the thickness direction of the ferromagnet. Unlike spintronic THz emitters reported previously, it does not require additional non-magnetic layer or Rashba interface.

description: Consistent aggregation assures that behavioral properties which apply to disaggregate relationships also apply to aggregate relationships. The agricultural economics literature is reviewed which has tested for consistent aggregation or measured statistical bias and/or inferential errors due to aggregation. Tests for aggregation bias and errors of inference are conducted using indices previously tested for consistent aggregation. Failure to reject consistent aggregation in a partition did not entirely mitigate erroneous inference due to aggregation. However, inferential errors due to aggregation were small relative to errors due to incorrect functional form or failure to account for time series properties of data.
Leitbilder für die Renaturierung von Flussauen schaffen

Year: 2020

description: Nur ein Bruchteil der Flussauen in Deutschland ist noch annähernd naturnah erhalten. Inzwischen gibt es in Mitteleuropa kaum noch Auensysteme, die uns zeigen können, welchen ökologischen Zustand wir überhaupt anstreben wollen. Ohne Zugeständnisse, insbesondere was die Flächenverfügbarkeit anbetrifft, wird sich am schlechten Zustand der Auen nichts ändern. Grundsätzlich sind Auensysteme hoch dynamische Systeme, die sich hervorragend regenerieren. Eine multifunktionale Nutzung durch verschiedene Wirtschaftsakteure ist dabei durchaus möglich. ■ Der Zustand von 90 Prozent der Auen ist deutlich bis stark verändert. ■ Auen stellen aber eine Vielzahl von Ökosystemleistungen zur Verfügung. ■ Es mangelt an konsensuellen Leitbildern, die es ermöglichen könnten, unter den derzeitigen Rahmenbedingungen ökologisch intakte Fluss- und Auenökosysteme wieder herzustellen. ■ Immerhin gibt es gute Beispiele für einen besseren Umgang mit Flüssen und Auen.

description: A method for determination of bound state energies for an asymmetric quantum well with an arbitrary shape of the bottom is suggested. It is shown that how the equation determining the energy levels can be easily derived if one knows the electron transmission and reflection amplitudes corresponding to the part of potential inside the well. The results are applied to three difference test problems.

Gravitational waves and cosmic magnetism; a cosmological approach

description: We present the formalism for the covariant treatment of gravitational radiation in a magnetized environment and discuss the implications of the field for gravity waves in the cosmological context. Our geometrical approach brings to the fore the tension properties of the magnetic force lines and reveals their intricate interconnection to the spatial geometry of a magnetised spacetime. We show how the generic anisotropy of the field can act as a source of gravitational wave perturbations and how, depending on the spatial curvature distortion, the magnetic tension can boost or suppress waves passing through a magnetized region.

BloatLibD: Detecting Bloated Libraries in Java Applications
Creators: name: Kapur, Ritu
Publisher: name: figshare
Year: 2021
Subjects: Applied Computer Science

description: Third-party libraries (TPLs) provide ready-made implementations of various software functionalities and are frequently used in software development. However, as software development progresses through various iterations, there often remains an unused set of TPLs referenced in the application’s distributable. These unused TPLs become a prominent source of software bloating and are responsible for excessive consumption of resources, such as CPU cycles, memory, and mobile devices’ battery-usage. Thus, the identification of such bloat-TPLs is essential. We present a rapid, storage-efficient, obfuscation-resilient method to detect the bloat-TPLs. Our approach’s novel aspects are i) Computing a vector representation of a .class file using a model that we call Jar2Vec. The Jar2Vec model is trained using the Paragraph Vector Algorithm. ii) Before using it for training the Jar2Vec models, a .class file is converted to a normalized form via semantics-preserving transformations. iii) A Bloated Library Detector (BloatLibD) developed and tested with 27 different Jar2Vec models. These models were trained using different parameters and >30000 .class files taken from >100 different Java libraries available at MavenCentral.com. BloatLibD achieves an accuracy of 99% with an F1 score of 0.968 and outperforms the existing tools, viz., LibScout, LiteRadar, and LibD with an accuracy improvement of 74.5%, 30.33%, and 14.1%, respectively. Compared with LibD, BloatLibD achieves a response time improvement of 61.37% and a storage reduction of 87.93%. Our program artifacts are available at https://bit.ly/2WFALXf.

description: Research on bacteriophages, the viruses infecting bacteria, has fueled the development of modern molecular biology and inspired their therapeutic application to combat bacterial multidrug resistance. However, most work has so far focused on a few model phages which impedes direct applications of these findings in clinics and suggests that a vast potential of powerful molecular biology has remained untapped. We have therefore recently composed the BASEL collection of Escherichia coli phages (BActeriophage SElection for your Laboratory) which made a relevant diversity of phages infecting the E. coli K-12 laboratory strain accessible to the community. These phages are widely used, but their assorted diversity had remained limited by the E. coli K-12 host. We have therefore now genetically overcome the two major limitations of E. coli K-12, its lack of O-antigen glycans and the presence of resident bacterial immunity. Restoring O-antigen expression resulted in the isolation of diverse additional viral groups like Kagunavirus, Nonanavirus, Gordonclarkvirinae, and Gamaleyavirus, while eliminating all known antiviral defenses of E. coli K-12 additionally enabled us to isolate phages of genus Wifcevirus. Even though some of these viral groups appear to be common in nature, no phages from any of them had previously been isolated using E. coli laboratory strains and they had thus remained largely understudied. Overall, 36 new phage isolates have been added to complete the BASEL collection. These phages were deeply characterized genomically and phenotypically with regard to host receptors, sensitivity to antiviral defense systems, and host range. These results highlighted dominant roles of the O-antigen barrier for viral host recognition and of restriction-modification systems in bacterial immunity. We anticipate that the completed BASEL collection will propel research on phage-host interactions and their molecular mechanisms, deepening our understanding of viral ecology and fostering innovations in biotechnology and antimicrobial therapy.

description: We present the results of a detailed study of how isocurvature axion fluctuations are converted into adiabatic metric perturbations through axion decay, and discuss the constraints on the parameters of pre-big bang cosmology needed for consistency with present CMB-anisotropy data. The large-scale normalization of temperature fluctuations has a non-trivial dependence both on the mass and on the initial value of the axion. In the simplest, minimal models of pre-big bang inflation, consistency with the COBE normalization requires a slightly tilted (blue) spectrum, while a strictly scale-invariant spectrum requires mild modifications of the minimal backgrounds at large curvature and/or string coupling.

description: Wetlands on private land generate both private and social values. The nature of these values is dependent on the biophysical status of the wetlands. Changes in land management can alter the biophysical status of wetlands and hence the values generated by wetlands. Land managers change management according to the private values they receive from their wetlands. However land management changes also affect social values. Bio-economic modelling of changes to wetland management incorporates the biological and economic impacts at a landscape scale. In turn the bio-economic modelling can be used to determine appropriate incentives at the farm scale to facilitate wetland protection on private land. In this paper we discuss the development of a bio-economic model for two case study areas: the Upper South East of South Australia; and, the Murrumbidgee River floodplain between Wagga Wagga and Hay.
