description: In a hybrid plasma solver (particle ions, fluid mass-less electrons) regions of vacuum, or very low charge density, can cause problems since the evaluation of the electric field involves division by charge density. This causes large electric fields in low density regions that can lead to numerical instabilities. Here we propose a self consistent handling of vacuum regions for hybrid solvers. Vacuum regions can be considered having infinite resistivity, and in this limit Faraday's law approaches a magnetic diffusion equation. We describe an algorithm that solves such a diffusion equation in regions with charge density below a threshold value. We also present an implementation of this algorithm in a hybrid plasma solver, and an application to the interaction between the Moon and the solar wind. We also discuss the implementation of hyperresistivity for smoothing the electric field in a PIC solver.

description: The characterization of plasticity, robustness, and evolvability, an important issue in biology, is studied in terms of phenotypic fluctuations. By numerically evolving gene regulatory networks, the proportionality between the phenotypic variances of epigenetic and genetic origins is confirmed. The former is given by the variance of the phenotypic fluctuation due to noise in the developmental process; and the latter, by the variance of the phenotypic fluctuation due to genetic mutation. The relationship suggests a link between robustness to noise and to mutation, since robustness can be defined by the sharpness of the distribution of the phenotype. Next, the proportionality between the variances is demonstrated to also hold over expressions of different genes (phenotypic traits) when the system acquires robustness through the evolution. Then, evolution under environmental variation is numerically investigated and it is found that both the adaptability to a novel environment and the robustness are made compatible when a certain degree of phenotypic fluctuations exists due to noise. The highest adaptability is achieved at a certain noise level at which the gene expression dynamics are near the critical state to lose the robustness. Based on our results, we revisit Waddington's canalization and genetic assimilation with regard to the two types of phenotypic fluctuations.

Olivine trace element geochemistry of volcanics from central and southern Africa

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Olivines from mantle derived igneous rocks, specifically kimberlites from the Kalahari craton and alkaline to ultrapotassic mafic volcanics from the western branch of the East African Rift System from two distinct volcanic fields of Toro-Ankole and Virunga, were analysed by LA-ICP- MS to determine their minor and trace element concentrations. Olivine trace element geochemistry has gained increasing attention over the last decade as even though olivine has a limited ability to uptake trace elements early crystallization gives it the ability to record the most primitive unaltered compositions of the melt. These minor and trace element characteristics are compared to the growing range of olivine datasets sourced from a range of tectonic environments as to ascertain clues to the composition and conditions of the mantle source of these melts. A crustal component is inferred to be present in leucite basanites and potassic trachybasalts from the Virunga field due to the elevated Li concentrations in olivine (9.48 ppm), well above the mantle average of 3 ppm. Elevated V/Sc in one of the ugandites from Toro-Ankole is caused by a phlogopite component in the source, and not variation in oxygen fugacity.

description: GRS 1915+105 has the largest mass function of any Galactic black hole system, although the error is relatively large. Here we present spectroscopic analysis of medium-resolution IR VLT archival data of GRS 1915+105 in the K-band. We find an updated ephemeris, and report on attempts to improve the mass function by a refinement of the radial velocity estimate. We show that the spectra are significantly affected by the presence of phase-dependent CO bandhead emission, possibly originating from the accretion disc: we discuss the impact this has on efforts to better constrain the black hole mass. We report on a possible way to measure the radial velocity utilising apparent H-band atomic absorption features and also discuss the general uncertainty of the system parameters of this well-studied object

description: It is argued that exotic mesons consisting of two quarks and two antiquarks are not ruled out in quantum chromodynamics with a large number $N$ of colors, as generally thought. They can come in two varieties: short-lived tetraquarks with decay rates proportional to $N$, which would be unobservable if $N$ were sufficiently large, and long-lived tetraquarks with decay rates proportional to 1/N. The $f_0(500)$ and $f_0(980)$ may be examples of these two varieties of exotic mesons.

description: The models for the internal structure of the newly found four-quark charmonium-like resonance $Z_c(3900)$ are discussed: the molecular model as well as the hadro-charmonium and tetraquark schemes. It is argued that it would be possible to resolve between these models by combining measurements of the quantum numbers of the resonance and of its decay rates into yet unseen channels $πψ'$, $πh_c$, $ρη_c$ and into pairs of heavy mesons $D^* \bar D$ and $D \bar D^*$. The models also predict different related four-quark states, which can be sought for in the existing and future data.

description: Proposed quantum networks require both a quantum interface between light and matter and the coherent control of quantum states. A quantum interface can be realized by entangling the state of a single photon with the state of an atomic or solid-state quantum memory, as demonstrated in recent experiments with trapped ions, neutral atoms, atomic ensembles, and nitrogen-vacancy spins. The entangling interaction couples an initial quantum memory state to two possible light-matter states, and the atomic level structure of the memory determines the available coupling paths. In previous work, these paths' transition parameters determine the phase and amplitude of the final entangled state, unless the memory is initially prepared in a superposition state, a step that requires coherent control. Here we report the fully tunable entanglement of a single 40Ca+ ion and the polarization state of a single photon within an optical resonator. Our method, based on a bichromatic, cavity-mediated Raman transition, allows us to select two coupling paths and adjust their relative phase and amplitude. The cavity setting enables intrinsically deterministic, high-fidelity generation of any two-qubit entangled state. This approach is applicable to a broad range of candidate systems and thus presents itself as a promising method for distributing information within quantum networks.

description: We draw attention to the existence of "genuine" fidelity gaps in an ancilla-assisted sequential decomposition of genuinely entangling isometry and unitary operations of quantum computing. The gaps arise upon a bipartite decomposition of a multiqubit operation in a one-way sequential recipe in which an ancillary system interacts locally and only once with each qubit in a row. Given the known "no-go" associated with such a theoretically and experimentally desirable decomposition, various figures of merit are introduced to analyze the optimal "fidelity" with which an arbitrary genuinely entangling operation may admit such a sequential decomposition. An efficient variational matrix-product-operator (VMPO) protocol is invoked in order to obtain numerically the minimal values of the fidelity gaps incurred upon sequential decomposition of genuine entanglers. We term the values of the gaps so obtained genuine in the light of possible connections to the concept of the genuine multipartite entanglement and since they are independent of the ancilla dimension and the initial states the associated unitaries act upon.

description: Cosmic-rays with energies up to $3\times10^{20}$ eV have been observed, as have as have astrophysical neutrinos with energies above 1 PeV. In this talk, I will discuss some of the unique phenomena that occur when particles with TeV energies and above interact with matter. The emphasis will be on lepton interactions. The cross-sections for electron bremsstrahlung and photon pair conversion are suppressed at high energies, by the Landau-Pomeranchuk-Migdal (LPM) effect, lengthening electromagnetic showers. At still higher energies (above $10^{20}$ eV), photonuclear and electronuclear interactions dominate, and showers become predominantly hadronic. Muons interact much less strongly, so can travel long distances through solids before losing energy. Tau leptons behave similarly, although their short livetime limits how far they can travel. The hadronic interaction cross-section is believed to continue to increase slowly with rising energy; measurements of cosmic-ray air showers support this prediction.

Understanding ocean highways: trends in surface currents and divergence in urbanized coastal margins for a predictable ocean
Creators: name: Stolarz, Timothy
Publisher: name: No Publisher Supplied
Year: 2022

description: In the New York – New Jersey Bight, research involving surface currents is available. However, research focusing on divergence is limited. This study focused on determining trends in surface current divergence in the New York – New Jersey Bight. This dataset consists of a 10-year span (2007–2016) of 5 MHz High Frequency Radar (HF Radar) surface current velocity profiles. For this study, the data was broken down into the following partitions: a 10-year mean, 10 annual means, 4 seasonal means, and 12 monthly means. For each year, the velocity means were split both seasonally and monthly, and the surface currents were then averaged during those periods, allowing for qualitative visual analysis on the resulting maps. For the purposes of this analysis, divergence values are represented as an upwelling vertical velocity and convergence values are represented as a downwelling vertical velocity [Manderson et al., 2011] in m/day.Findings indicate persistent upwelling at the head of the Hudson Shelf Valley (HSV) with average vertical velocities averaging 0.15 m/day throughout the 10-year period. In the mid-shelf, there is high inter-annual and inter-seasonal variability leading to low average values of divergence (± 0.10 m/day) due to constant shifts in the divergence or convergence. This strong variability phenomenon is seen most prominently in the cross-shelf divergence patterns of the New York – New Jersey Bight, with prevalent cross-shelf divergence in the winter, spring, and fall. In the far-shelf, there tends to be along-shelf divergence patterns between the 50 – 80 m isobath from velocities increasing as the shelf deepens toward the 200 m isobath likely due to increasing velocities of the Shelfbreak Jet. Winter is the only season to be prominently upwelling of all the seasons which can be attributed to the intense cross shelf winds found during the winter.Areas of persistent divergence such as the head of the HSV can create regions of bioproductivity leading to increases in species richness, recruitment success rates, and potential formation of harmful algal blooms. Cross-shelf ‘bridges’ of divergent flows can facilitate the cross-shelf migrations of anadromous and catadromous species along with regular cross-shelf migrators such as the bluefish.
Dynamic and resilient Meadowlands: designing the future of the New Jersey Meadowlands
Creators: name: Pullin, Henry
Publisher: name: No Publisher Supplied
Year: 2022

description: The Meadowlands are a large brackish estuarine complex located in northern New Jersey. The area is located just 6 miles from Manhattan and currently contains about 8,400 acres of open, undeveloped space that is surrounded on all sides by a dense urban environment. Centuries of anthropogenic disturbance of natural areas has resulted in the entirety of the Meadowlands transitioning into a novel ecosystem. The intent of this thesis is to understand how the Meadowlands arrived at its current state and what the future hold for the area. This is done through an investigation of the large scale and transformative changes that have occurred in this wetland area. Special attention is paid to human influence and landscape modification that has occurred throughout the Meadowlands. A design for an urban wetland park is then proposed. The proposed site planning, restoration and management methods are justified based on the analysis performed earlier in the thesis. The proposed park embraces the novel ecology of the Meadowlands and harnesses the dynamism of the Meadowlands to create a sustainable and resilient wetland park. The park proposal is made up of a “tool kit” of restoration and design interventions that has the potential to be implemented throughout the Meadowlands to solve many existing issues posed by sea level rise, storm flooding, habitat loss and fragmentation, and limited access to nature in the surrounding urban environment.

description: Many applications of speech communication and speaker identification suffer from the problem of co-channel speech. This paper deals with a multi-resolution dyadic wavelet transform method for usable segments of co-channel speech detection that could be processed by a speaker identification system. Evaluation of this method is performed on TIMIT database referring to the Target to Interferer Ratio measure. Co-channel speech is constructed by mixing all possible gender speakers. Results do not show much difference for different mixtures. For the overall mixtures 95.76% of usable speech is correctly detected with false alarms of 29.65%.

This search considers the pair production of top squarks and is sensitive across a wide range of mass differences between the top squark and the lightest neutralino. Additionally, spin-0 mediator dark-matter models are considered, in which the mediator is produced in association with a pair of top quarks. The mediator subsequently decays to a pair of dark-matter particles. No significant excess of events is observed above the Standard Model background, and limits are set at $95\%$\ confidence level. The results exclude top squark masses up to about $1$ TeV, and masses of the lightest neutralino up to about $500$ GeV. Limits on dark-matter production are set for scalar (pseudoscalar) mediator masses up to about $250~(300)$ GeV.

description: Open lattices are characterized by low volume-fraction arrangements of building blocks, low coordination number, and open spaces between building blocks. The self-assembly of these lattices faces the challenge of mechanical instability due to their open structures. We theoretically investigate the stabilizing effects of entropy in the self-assembly of open lattices from patchy particles. A preliminary account of these findings and their comparison to experiment was presented recently [X. Mao, Q. Chen, S. Granick, \textit{Nat. Mater.}, \textbf{12}, 217 (2013)]. We found that rotational entropy of patchy particles can provide mechanical stability to open lattices, whereas vibrational entropy of patchy particles can lower the free energy of open lattices and thus enables the selection of open lattices verses close-packed lattices which have the same potential energy. These effects open the door to significant simplifications of possible future designs of patchy-particles for open-lattice self-assembly.

Kurz gefasst:
Die bereits seit dem Jahr 1992 bestehende Möglichkeit, eine Teilrente zu beziehen und die Erwerbstätigkeit parallel (teilweise) fortzuführen, hat als Übergangspfad in den Ruhestand bislang kaum Anklang gefunden. Die Neuregelung macht die Kombinations- und Hinzuverdienstmöglichkeiten von Teilrente und Erwerbseinkommen deutlich attraktiver.
Das Gesetz sieht außerdem eine Ausweitung der Vorsorgemöglichkeiten im Altersübergang vor. So sind zukünftig auch die Minijobs bei vorgezogenen Altersrenten versicherungspflichtig. Außerdem werden die Rentenansprüche für erwerbstätige RentnerInnen jenseits der Regelaltersgrenze individualisiert. Während die (reinen) Arbeitgeberabgaben bislang anonym der Rentenkasse zuflossen, werden sie ab 2017 dem/der jeweiligen RentnerIn gutgeschrieben – sofern er sich an der Abgabe durch einen eigenen Beitrag beteiligt. Auf diese Weise wird ein faires Angebot geschaffen, die Rente auch in der Auszahlungsphase noch zu erhöhen.
Die Möglichkeit, im Rentenalter erwerbstätig zu sein und dabei Alterssicherung zu betrieben, bleibt jedoch all jenen vorbehalten, die dazu gesundheitlich und qualifikatorisch in der Lage sind. Die Empirie zeigt, dass im Rentenalter vor allem gut qualifizierte, gesunde Ältere vorwiegend Teilzeittätigkeiten ausüben, deren Arbeitsinhalte oft deutlich unter ihrem Qualifikationsniveau liegen. Sowohl die Hoffnung, mit der Erwerbstätigkeit im Rentenalter Absicherungslücken zu schließen, als auch die Idee, auf diese Weise dem Fachkräftemangel zu begegnen, wird daher unerfüllt bleiben.

The particles were synthesized by means of a metathesis reaction between sodium silicide (Na4Si4) and silicon tetrachloride (SiCl4) and were surface functionalized with a variety of passivating ligands. The synthesis scheme results in particles of diameter ~10 nm with long size-adjusted 29Si spin lattice relaxation (T1) times (> 600 s), which are retained after hyperpolarization by low temperature DNP.

description: A simple discrete planar dynamical model for the ideal (logical) R-S flip-flop circuit is developed with an eye toward mimicking the dynamical behavior observed for actual physical realizations of this circuit. It is shown that the model exhibits most of the qualitative features ascribed to the R-S flip-flop circuit, such as an intrinsic instability associated with unit set and reset inputs, manifested in a chaotic sequence of output states that tend to oscillate among all possible output states, and the existence of periodic orbits of arbitrarily high period that depend on the various intrinsic system parameters. The investigation involves a combination of analytical methods from the modern theory of discrete dynamical systems, and numerical simulations that illustrate the dazzling array of dynamics that can be generated by the model. Validation of the discrete model is accomplished by comparison with certain Poincaré map like representations of the dynamics corresponding to three-dimensional differential equation models of electrical circuits that produce R-S flip-flop behavior.

description: SimpleAnalysis implementation
description: The results of a search for direct pair production of top squarks and for dark matter in events with two opposite-charge leptons (electrons or muons), jets and missing transverse momentum are reported, using 139~\mbox{fb\(^{-1}\)} of integrated luminosity from proton--proton collisions at $\sqrt{s}=13$ TeV, collected by the ATLAS detector at the Large Hadron Collider during Run~2 (2015--2018). This search considers the pair production of top squarks and is sensitive across a wide range of mass differences between the top squark and the lightest neutralino. Additionally, spin-0 mediator dark-matter models are considered, in which the mediator is produced in association with a pair of top quarks. The mediator subsequently decays to a pair of dark-matter particles. No significant excess of events is observed above the Standard Model background, and limits are set at $95\%$\ confidence level. The results exclude top squark masses up to about $1$ TeV, and masses of the lightest neutralino up to about $500$ GeV. Limits on dark-matter production are set for scalar (pseudoscalar) mediator masses up to about $250~(300)$ GeV.

description: Localised states are found in many pattern forming systems. The aim of this paper is to investigate the occurrence of oscillatory localised states in two-dimensional Boussinesq magnetoconvection. Initially considering an idealised model, in which the vertical structure of the system has been simplified by a projection onto a small number of Fourier modes, we find that these states are restricted to the low $ζ$ regime (where $ζ$ represents the ratio of the magnetic to thermal diffusivities). These states always exhibit bistability with another non-trivial solution branch, in other words they show no evidence of subcritical behaviour. This is due to the weak flux expulsion that is exhibited by these time-dependent solutions. Using the results of this parameter survey, we locate corresponding states in a fully-resolved two-dimensional system, although the mode of oscillation is more complex in this case. This is the first time that a localised oscillatory state, of this kind, has been found in a fully-resolved magnetoconvection simulation.

description: We study one-dimensional Schrödinger operators $\mathrm{S}(q)$ on the space $L^{2}(\mathbb{R})$ with potentials $q$ being complex-valued generalized functions from the negative space $H_{unif}^{-1}(\mathbb{R})$. Particularly the class $H_{unif}^{-1}(\mathbb{R})$ contains periodic and almost periodic $H_{loc}^{-1}(\mathbb{R})$-functions. We establish an equivalence of the various definitions of the operators $\mathrm{S}(q)$, investigate their approximation by operators with smooth potentials from the space $L_{unif}^{1}(\mathbb{R})$ and prove that the spectrum of each operator $\mathrm{S}(q)$ lies within a certain parabola.

description: Two popular methods to reduce discretisation effects are Symanzik improvement and gauge field smearing in the Dirac operator. Tree-level $O(a^2)$-improved Wilson fermions can be obtained from $O(a)$-improved Wilson fermions by adding one dimension-6 operator to the action. For gauge field smearing one wants to avoid the situation when too much smearing leads to uncontrolled continuum extrapolations as the short distance behaviour is mutilated. We focus on the gradient flow formalism as it allows to study both smearing and physical flow. We investigate the effect of smearing on the scaling towards the continuum limit in pure gauge theory on the example of Creutz ratios, which provide a measure of the physical forces felt by the fermions. For suitable smearing strengths we also investigate the change when the Wilson gradient flow is replaced by stout smearing.

description: Ease of access to and low cost of hardware and software for 3D scanning have made 3D technologies increasingly popular in recent research. One of the possible 3D scanning approaches is photogrammetry which relies on using a data set consisting of photographs of the same physical object. In this paper are evaluated different 3D models generated from the same input data set by specialised software packages for photogrammetry. The main attributes of the 3D models are examined in comparative analyses and their differences highlighted. Furthermore, visual qualitative inspections are performed on the models and the results are compared.

description: About this story: In this StoryMap, we focus on the risk connected to the COVID-19 pandemic in São Paulo, one of the largest cities in Latin America. São Paulo ist the economic center of South America, and the richest city in Brazil. At the same time, the inequality is very high. This show the values of the Human Development Index. Its levels vary within the metropolitan region from 0,479 in Vila César to 0,965 in Berrini, Jardim Paulistano, and Vila Madalena. These districts are located in the capital and represent a rough equivalent to Yemen (Vila César) or to that of Norway (Vila Madalena), the highest ranked in 2021.

description: Many patterns have been uncovered in complex systems through the application of concepts and methodologies of complex networks. Unfortunately, the validity and accuracy of the unveiled patterns are strongly dependent on the amount of unavoidable noise pervading the data, such as the presence of homonymous individuals in social networks. In the current paper, we investigate the problem of name disambiguation in collaborative networks, a task that plays a fundamental role on a myriad of scientific contexts. In special, we use an unsupervised technique which relies on a particle competition mechanism in a networked environment to detect the clusters. It has been shown that, in this kind of environment, the learning process can be improved because the network representation of data can capture topological features of the input data set. Specifically, in the proposed disambiguating model, a set of particles is randomly spawned into the nodes constituting the network. As time progresses, the particles employ a movement strategy composed of a probabilistic convex mixture of random and preferential walking policies. In the former, the walking rule exclusively depends on the topology of the network and is responsible for the exploratory behavior of the particles. In the latter, the walking rule depends both on the topology and the domination levels that the particles impose on the neighboring nodes. This type of behavior compels the particles to perform a defensive strategy, because it will force them to revisit nodes that are already dominated by them, rather than exploring rival territories. Computer simulations conducted on the networks extracted from the arXiv repository of preprint papers and also from other databases reveal the effectiveness of the model, which turned out to be more accurate than traditional clustering methods.

description: We present a method to generate qubits of the vibrational motion of an ion. The method is developed in the non-rotating wave approximation regime, therefore we consider regimes where the dynamics has not been studied. Because the solutions are valid for a more extended range of parameters we call them generalized qubits.
