A dynamical system approach to data assimilation in chaotic models
Creators: name: Pilolli, Massimo <1966>

description: The Assimilation in the Unstable Subspace (AUS) was introduced by Trevisan and Uboldi
in 2004, and developed by Trevisan, Uboldi and Carrassi, to minimize the analysis and forecast
errors by exploiting the flow-dependent instabilities of the forecast-analysis cycle system, which
may be thought of as a system forced by observations. In the AUS scheme the assimilation is
obtained by confining the analysis increment in the unstable subspace of the forecast-analysis
cycle system so that it will have the same structure of the dominant instabilities of the system.
The unstable subspace is estimated by Breeding on the Data Assimilation System (BDAS). AUS-
BDAS has already been tested in realistic models and observational configurations, including a
Quasi-Geostrophicmodel and a high dimensional, primitive equation ocean model; the experiments
include both fixed and“adaptive”observations. In these contexts, the AUS-BDAS approach greatly
reduces the analysis error, with reasonable computational costs for data assimilation with respect,
for example, to a prohibitive full Extended Kalman Filter.
This is a follow-up study in which we revisit the AUS-BDAS approach in the more basic, highly
nonlinear Lorenz 1963 convective model. We run observation system simulation experiments in a
perfect model setting, and with two types of model error as well: random and systematic. In the
different configurations examined, and in a perfect model setting, AUS once again shows better
efficiency than other advanced data assimilation schemes. In the present study, we develop an
iterative scheme that leads to a significant improvement of the overall assimilation performance
with respect also to standard AUS. In particular, it boosts the efficiency of regime’s changes
tracking, with a low computational cost.
Other data assimilation schemes need estimates of ad hoc parameters, which have to be tuned
for the specific model at hand. In Numerical Weather Prediction models, tuning of parameters —
and in particular an estimate of the model error covariance matrix — may turn out to be quite
difficult. Our proposed approach, instead, may be easier to implement in operational models.

Towards a Supersymmetric Generalization of the Schwarzschild Black Hole

description: The Wheeler-DeWitt (WDW) equation for the Kantowski-Sachs model can also be understood as the WDW-equation corresponding to the Schwarzschild black hole due to the well known diffeomorphism between these two metrics. The WDW-equation and its solutions are ``ignorant'' of the coordinate patch one is using, only by imposing coordinate conditions we can differentiate between cosmological and black hole models. At that point, the foliation parameter $t$ or $r$ will appear in the solution of interest. In this work we supersymmetrize this WDW-equation obtaining an extra term in the potential with two possible signs. The WKB method is then applied, given rise to two classical equations. It is shown that the event horizon can never be reached because, very near to it the extra term in the potential, for each one of the equations, is more relevant than the one that corresponds to Schwarzschild. One can then study the asymptotic cases in which one of the two terms in the Hamiltonian dominates the behavior. One of them corresponds to the usual Schwarzschild black hole. We will study here the other two asymptotic regions; they provide three solutions. All of them have a singularity in $r=0$ and depending on an integration constant $C$ they can also present a singularity in $r=C^2$. Neither of these solutions have a Newtonian limit. The black hole solution we study is analyzed between the singularity $r=C^2$ and a maximum radius $r_m$. We find an associated mass, considering the related cosmological solution inside $r=C^2$, and based on the holographic principle an entropy can be assigned to this asymptotic solution.

Rehistoricizing the Nile Waters Agreement, 1948–1963 The view from the British Colonial Office and its afterlife
Creators: name: Doyle-Raso, John
Publisher: name: International Journal of Water Governance
Year: 2022

description: This article examines the final years of colonialism and the establishment of independent government in East Africa, particularly Uganda. It finds that the British broke from the Nile Wa- ters Agreement by not only ceasing to recognize it but by also circumventing the process for ensuring treaty compliance. They did so on behalf of foreign investors seeking irrigation water. Furthermore, this article shows why the colonial government in Uganda integrated the proposal to flood Lake Albert – which would displace many Ugandans – into discussions about the treaty. The government based this decision on Cold War politics, the personal biases of its advisers and technocratic designs for resettling the region. To contextualize the lack of scholarly analysis re- garding these issues, this article examines how former colonial officials became diplomats, then scholars, who downplayed their treaty breakage and their roles supporting the proposal to flood Lake Albert. Providing further context for the lack of analysis regarding Uganda, it shows how the independent Ugandan government navigated the ambiguous situation that the British left. It also finds that scholars have reproduced the Lake Albert proposal without considering its local signifi- cance. I conclude that although the colonial breakage from the Nile Waters Agreement left the in- dependent governments with no relationship to it, the present role of the Ugandan government in Nile governance is part of a resurgence of foreign investments in East Africa. Outsider control of Lake Victoria is becoming entrenched even as the influence of the Nile Waters Agreement wanes.

description: The direct detection of gravitational waves will provide valuable astrophysical information about many celestial objects. The most promising sources of gravitational waves are neutron stars and black holes. These objects emit waves in a very wide spectrum of frequencies determined by their quasi-normal modes oscillations. In this work we are concerned with the information we can extract from f and p$_I$-modes when a candidate leaves its signature in the resonant mass detectors ALLEGRO, EXPLORER, NAUTILUS, MiniGrail and SCHENBERG. Using the empirical equations, that relate the gravitational wave frequency and damping time with the mass and radii of the source, we have calculated the radii of the stars for a given interval of masses $M$ in the range of frequencies that include the bandwidth of all resonant mass detectors. With these values we obtain diagrams of mass-radii for different frequencies that allowed to determine the better candidates to future detection taking in account the compactness of the source. Finally, to determine which are the models of compact stars that emit gravitational waves in the frequency band of the mass resonant detectors, we compare the mass-radii diagrams obtained by different neutron stars sequences from several relativistic hadronic equations of state (GM1, GM3, TM1, NL3) and quark matter equations of state (NJL, MTI bag model). We verify that quark stars obtained from MIT bag model with bag constant equal to 170 MeV and quark of matter in color-superconductivity phase are the best candidates for mass resonant detectors.

description: "Hard" massive black hole (MBH) binaries embedded in steep stellar cusps can shrink via three-body slingshot interactions. We show that this process will inevitably be accompanied by a burst of stellar tidal disruptions, at a rate that can be several orders of magnitude larger than that appropriate for a single MBH. Our numerical scattering experiments reveal that: 1) a significant fraction of stars initially bound to the primary hole are scattered into its tidal disruption loss cone by gravitational interactions with the secondary hole, an enhancement effect that is more pronounced for very unequal-mass binaries; 2) about 25% (40%) of all strongly interacting stars are tidally disrupted by a MBH binary of mass ratio q=1/81 (q=1/243) and eccentricity 0.1; and 3) two mechanisms dominate the fueling of the tidal disruption loss cone, a Kozai non-resonant interaction that causes the secular evolution of the stellar angular momentum in the field of the binary, and the effect of close encounters with the secondary hole that change the stellar orbital parameters in a chaotic way. For a hard MBH binary of 10^7 solar masses and mass ratio 0.01, embedded in an isothermal stellar cusp of velocity dispersion sigma*=100 km/s, the tidal disruption rate can be as large as 1/yr. This is 4 orders of magnitude higher than estimated for a single MBH fed by two-body relaxation. When applied to the case of a putative intermediate-mass black hole inspiraling onto Sgr A*, our results predict tidal disruption rates ~0.05-0.1/yr.

Precise Positions of Methanol Masers

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The Australia Telescope Compact Array (ATCA) has been used to determine positions for many southern methanol maser sites, with accuracy better than 1 arcsec. The results are presented here as a catalogue of more than 350 distinct sites, some of them new discoveries, and many others with positional precision 10 times better than existing published values. Clusters of 2 or 3 sites are occasionally found to account for single previously listed sources. This in turn reveals that the velocity range for each individual site is sometimes smaller than that of the originally tabulated (blended) source. Only a handful of examples then remain with a velocity range of more than 16 km/s at a single compact (less than 2 arcsec) site. The precise methanol positions now allow apparent coincidences with OH masers to be confidently accepted or rejected; this has led to the important conclusion that, where a 1665-MHz OH maser lies in a massive star formation region, at more than 80 percent of the OH sites there is a precisely coincident methanol maser. The methanol precision achieved here will also allow clear comparisons with likely associated IR sources when the next generation of far-IR surveys produce precise positions.

description: Non-Hermitian parity-time ($\mathcal{PT}$) and anti-parity-time ($\mathcal{APT}$)-symmetric systems exhibit novel quantum properties and have attracted increasing interest. Although many counterintuitive phenomena in $\mathcal{PT}$- and $\mathcal{APT}$-symmetric systems were previously studied, coherence flow has been rarely investigated. Here, we experimentally demonstrate single-qubit coherence flow in $\mathcal{PT}$- and $\mathcal{APT}$-symmetric systems using an optical setup. In the symmetry unbroken regime, we observe different periodic oscillations of coherence. Particularly, we observe two complete coherence backflows in one period in the $\mathcal{PT}$-symmetric system, while only one backflow in the $\mathcal{APT}$-symmetric system. Moreover, in the symmetry broken regime, we observe the phenomenon of stable value of coherence flow. We derive the analytic proofs of these phenomena and show that most experimental data agree with theoretical results within one standard deviation. This work opens avenues for future study on the dynamics of coherence in $\mathcal{PT}$- and $\mathcal{APT}$-symmetric systems.

description: The vicinity of the unidentified EGRET source 3EG J1420-6038 has undergone extensive study in the search for counterparts, revealing the energetic young pulsar PSR J1420-6048 and its surrounding wind nebula as a likely candidate for at least part of the emission from this bright and extended gamma-ray source. We report on new Suzaku observations of PSR J1420-6048, along with analysis of archival XMM Newton data. The low background of Suzaku permits mapping of the extended X-ray nebula, indicating a tail stretching ~8' north of the pulsar. The X-ray data, along with archival radio and VHE data, hint at a pulsar birthsite to the North, and yield insights into its evolution and the properties of the ambient medium. We further explore such properties by modeling the spectral energy distribution (SED) of the extended nebula.

description: Electronic properties of the single crystal of GdV6Sn6, where non-magnetic V-kagome layers are separated by magnetic Gd-triangular lattice, are investigated. GdV6Sn6 exhibits unique magnetotransport properties at low-temperature such as non-linear Hall resistivity and increase of resistance R in magnetic field H as R ~ H^0.75 up to 56 T with Shubnikov-De Haas oscillations. Investigation of the non-magnetic analogue YV6Sn6 and the first principles calculations reveal these properties are relevant to the bands arising from the V-kagome layer. A magnetic transition at 5 K in GdV6Sn6 modifies the transport properties, pointing to a coupling between Gd-spins on the triangular lattice and carriers in the V-kagome layer.

description: We explore the nature of the classical propagation of light through media with strong frequency-dependent dispersion in the presence of a gravitational field. In the weak field limit, gravity causes a redshift of the optical frequency, which the slow-light medium converts into a spatially-varying index of refraction. This results in the bending of a light ray in the medium. We further propose experimental techniques to amplify and detect the phenomenon using weak value measurements. Independent heuristic and rigorous derivations of this effect are given.

description: Neuroendocrine neoplasms (NENs) are a diverse group originating from endocrine cells/their precursors in pancreas, small intestine, or lung. The key serum marker is chromogranin A (CgA). While commonly elevated in patients with NEN, its prognostic value is still under discussion. Secretion/posttranslational proteolytic cleavage of CgA results in multiple bioactive fragments, which are essential regulators of the cardiovascular and immune system. miR-223, regulator of Nrlp3 inflammasome and neutrophil activation, was recently found to have decreased in patients with NEN. We performed flow cytometry of circulating neutrophils in a patient cohort (n = 10) with NEN, microdissection and histology of tumor tissue. Subsequently, in vitro transfections using the well-established human pancreatic NEN cell line (BON), and co-culture experiments with primary macrophages and neutrophils were performed. Serum miR-223 in patients correlated with the expression of the neutrophil activation marker CD15 in circulating cells. Neutrophilic CD62L/CD63 showed good discrimination compared to healthy controls. Immune cell-derived miR-155, miR-193 and miR-223 colocalize with neutrophil in the extra-tumoral tissue alongside Nlrp3-associated caspase-1 activation. miR-223 knockdown in BON decreased the CgA intracellularly, increased in cellular granularity and caspase-1 activation. Plasmin inhibitor a2-aP reverted those effects. Western Blot showed fragmented CgA following miR-223 knockdown, which altered the inflammatory potential of neutrophils. Our data hence provide initial insights into an immunoregulatory mechanism via miR-223 and CgA in NEN cells, as regulation of miR-223 in NEN may affect tumor-associated inflammation.

description: Magnetic properties of an antiferromagnetic double perovskite oxide Ba2CaReO6, where Re6+ (5d1) ions with large spin-orbit coupling are arranged on the face-centered-cubic lattice, are investigated using pulsed high magnetic field up to 66 T. Magnetization and magnetostriction measurements have revealed a magnetic field induced phase transition at around 50 T. The phase transition accompanies a jump of magnetization and longitudinal magnetostriction of approximately 2 10^(-4) with the change of power law behavior, indicating sizable coupling between the electronic degrees of freedom and the lattice. The high field phase exhibits a magnetic moment approximately 0.2 μB, which is close to the values observed in 5d1 double perovskite oxides with non-collinear magnetic structure. We argue that Ba2CaReO6 is an antiferromagnet that sits close to the phase boundary between the collinear and non-collinear phases, providing the target material for investigating the interplay between spin-orbital entangled electrons and magnetic field.

description: Genetic variants associated with human diseases are often located outside the protein coding regions of the genome. Identification and functional characterization of the regulatory elements in the non-coding genome is therefore of crucial importance for understanding the consequences of genetic variation and the mechanisms of disease. The past decade has seen rapid progress in high-throughput analysis and mapping of chromatin accessibility, looping, structure, and occupancy by transcription factors, as well as epigenetic modifications, all of which contribute to the proper execution of regulatory functions in the non-coding genome. Here, we review the current technologies for the definition and functional validation of non-coding regulatory regions in the genome.

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We examine the fate of fast electrons (with energies E>10 eV) in a thermal gas of primordial composition. To follow their interactions with the background gas, we construct a Monte Carlo model that includes: (1) electron-electron scattering (which transforms the electron kinetic energy into heat), (2) collisional ionization of hydrogen and helium (which produces secondary electrons that themselves scatter through the medium), and (3) collisional excitation (which produces secondary photons, whose fates we also follow approximately). For the last process, we explicitly include all transitions to upper levels n<=4, together with a well-motivated extrapolation to higher levels. In all cases, we use recent calculated cross-sections at E<1 keV and the Bethe approximation to extrapolate to higher energies. We compute the fractions of energy deposited as heat, ionization (tracking HI and the helium species separately), and excitation (tracking HI Lyman-alpha separately) under a broad range of conditions appropriate to the intergalactic medium. The energy deposition fractions depend on both the background ionized fraction and the electron energy but are nearly independent of the background density. We find good agreement with some, but not all, previous calculations at high energies. Electronic tables of our results are available on request.

We prove that, in both cases, the only solution is AdS_5 x S^5 itself.

description: The study examined the availability and utilization of educational facilities and academic achievement of public secondary school students in Lagos State, Nigeria. Eight research questions and six null hypotheses guided the study. The study is a correlational survey adopting the ex-post-facto research design method. The population of the study was 19982 comprising all the 676 Principals of the public secondary schools, 1352 Vice Principals, and 17954 teachers from the six Education Districts of Lagos State. The cluster and simple random sampling technique was used to obtain a sample size of 999 secondary school teachers, vice principals and principals for the study. Two self-developed instruments, the checklist and SS2 promotion examination results were used to collect data for this study. The validity of the instrument was established through face and content validity. Reliability for the availability and utilization of educational facilities checklist was tested using the test, retest method. The test yielded a co-efficient of 0.82, data collected from the field was presented in tables and analyzed using the statistical tools of percentage, mean, and standard deviation to answer the research questions. Items with mean value of less than 2.50 were rejected. To test the hypotheses, the Pearson moment correlation coefficient (r) method was used, acceptance decision was determined at 0.05 level of significance. The extent of availability of educational facilities for academic achievement of public secondary school students in Lagos was high; The extent of utilization of educational facilities for academic achievement was high and there is a significant correlation between the availability and utilization of educational facilities and students’ academic achievement of Public Secondary School Students in Lagos State. Based on the findings, it was recommended that training should be organized for teachers and students on the benefits of utilizing available resources effectively. Government should implement a system for regularly assessing the conditions and functionality of educational facilities, this will help to identify areas of improvement ensuring that available facilities are well maintained for their optimal utilization for students’ academic achievement.

description: The nitrate-based compounds are seriously poisonous to the environment, ecology, and human life. The environmental systems are contaminated with the propagation of nitrate-based compounds. To keep all the sources of water safe, there is a need to monitor the contaminated ions regularly as water pollution is a major concern globally. Therefore, the correct application of methods for the detection and quantification of nitrate from environmental samples is a crucially important task in analytical chemistry. On the other hand, with no less importance, the developing new routes for removal of this pollutant from the environmental system is a striking purpose for the scientists. This manuscript provides an overview of the importance of monitoring and detecting nitrate-based compounds in environmental samples, as well as removing them to ensure safety of water resources. Various modern analytical chemistry methods for detecting and quantifying nitrate, such as spectrophotometric method, infrared spectroscopy, atomic absorption spectroscopic method, nuclear magnetic resonance method, chromatography, biosensors, and Raman spectroscopy method are reviewed and discussed in depth. The review also highlights the significance of developing new removal routes for nitrate contaminants in the environment. This review covers the main characteristics, fundamental concepts, recent trends, and future perspectives of these modern detection and removal techniques. By including all these elements in this review, it can give readers a comprehensive understanding of the discussed issues and will serve as a valuable contribution to the scrutinised fields.
Unconventional rotational responses of hadronic superfluids in a neutron star caused by strong entrainment and a $Σ^-$ hyperon gap

description: I show that the usual model of the rotational response of a neutron star, which predicts rotation-induced neutronic vortices and no rotation-induced protonic vortices, does not hold (i) beyond a certain threshold of entrainment interaction strength nor (ii) in case of nonzero $Σ^-$ hyperon gap. I demonstrate that in both these cases the rotational response involves creation of phase windings in electrically charged condensate. Lattices of bound states of vortices which are caused these effects can (for a range of parameters) strongly reduce the interaction between rotation-induced vortices with magnetic-field carrying superconducting components.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I review the development of ideas regarding the angular momentum evolution of solar-type stars, from the early 60's to the most recent years. Magnetic fields are the central agent that dictates the rotational evolution of solar-type stars, both during the pre-main sequence, through star-disk magnetic coupling, and during the main sequence, through magnetized winds. Key theoretical developments as well as important observational results are summarized in this review.

description: Under a particular choice of the Ernst potential, we solve analytically the Einstein-Maxwell equations to derive a new exact solution depending on five parameters: the mass, the angular-momentum (per unit mass), the electromagnetic-field strength, k, the parameter-p and the Kerr-NUT parameter, l. This (Petrov Type D) solution is cylindrically-symmetric and represents the curved background around a charged, rotating cosmic string, surrounded by gravitational and electromagnetic waves, under the influence of the Kerr-NUT parameter. A C-energy study in the radiation zone suggests that both the incoming and the outgoing radiation is gravitational, strongly focused around the null direction and preserving its profile. In this case, the absence of the k-parameter from the C-energy implies that, away from the linear defect the electromagnetic field is too weak to contribute to the energy-content of the cylindrically-symmetric space-time under consideration. In order to explain this result, we have evaluated the Weyl and the Maxwell scalars near the axis of the linear defect and at the spatial infinity. Accordingly, we have found that the electromagnetic field is concentrated (mainly) in the vicinity of the axis, while falling-off prominently at large radial distances. However, as long as k differs from unity, the non-zero Kerr-NUT parameter enhances those scalars, both near the axis and at the spatial infinity, introducing some sort of gravitomagnetic contribution.

description: We proudly relaunch the International Journal of Water Governance. Free to read, free to publish in and peer reviewed as ever, it is now also open to practitioner contributions and commentaries. We (non-exhaustively) lay out some of our key water governance concerns and interests in the interrelationships between nature, society and technology that produce water governance, such as emerging ideas and imaginaries, ‘institutional spaghetti’, representation, recognition and (re)distribution as well as sociotechnical systems. We invite a range of potential approaches but would encourage power-sensitivity in the analysis. Your contributions are most welcome, whether insightful overviews or groundbreaking ideas, no matter how contrarian, as long as they are well argued and based in fact!

Metal-insulator transition through a semi-Dirac point in oxide nanostructures: VO$_2$ (001) layers confined within TiO$_2$

description: Multilayer (TiO$_2$)$_m$/(VO$_2$)$_n$ nanostructures ($d^1$ - $d^0$ interfaces with no polar discontinuity) show a metal-insulator transition with respect to the VO$_2$ layer thickness in first principles calculations. For $n$ $\geq$ 5 layers, the system becomes metallic, while being insulating for $n$ = 1 and 2. The metal-insulator transition occurs through a semi-Dirac point phase for $n$ = 3 and 4, in which the Fermi surface is point-like and the electrons behave as massless along the zone diagonal in k-space and as massive fermions along the perpendicular direction. We provide an analysis of the evolution of the electronic structure through this unprecedented insulator-to-metal transition, and identify it as resulting from quantum confinement producing a non-intuitive orbital ordering on the V $d^1$ ions, rather than being a specific oxide interface effect. Spin-orbit coupling does not destroy the semi-Dirac point for the calculated ground state, where the spins are aligned along the rutile c-axis, but it does open a substantial gap if the spins lie in the basal plane.

description: A black hole (BH) hyperaccretion system might be born after the merger of a BH and a neutron star (NS) or a binary NS (BNS). In the case of a high mass accretion rate, the hyperaccretion disk is in a state of neutrino-dominated accretion flow (NDAF) and emits numerous anisotropic MeV neutrinos. Only a small fraction of these neutrinos annihilates in the space outside of the disk and then launch ultrarelativistic jets that break away from the merger ejecta to power gamma-ray bursts. Mergers and their remnants are generally considered sources of gravitational waves (GWs), neutrinos, and kilonovae. Anisotropic neutrino emission and anisotropic high-velocity material outflows from central BH-NDAF systems can also trigger strong GWs and luminous disk-outflow-driven (DOD) kilonovae, respectively. In this paper, the anisotropic multimessenger signals from NDAFs with outflows, including DOD kilonovae, MeV neutrinos, and GWs, are presented. As the results, the typical AB magnitude of the DOD kilonovae is lower than that of AT 2017gfo at the same distance, and it decreases with increasing viewing angles and its anisotropy is not sensitive to the outflow mass distribution but mainly determined by the velocity distribution. Since neutrinos with $\gtrsim 10~\rm MeV$ are mainly produced in the inner region of the disk, they will be dramatically deflected to a large viewing angle by relativity effects. Moreover, the strains of GWs induced by anisotropic neutrinos increase with increasing viewing angles. The accumulation of multimessenger detection of the BH-NS/BNS mergers with different viewing angles might further verify the existence of NDAFs with outflows.
