description: A series of multi-anvil experiments have been conducted to define the iron-rich liquidus of the ironnickel- sulfur (Fe-Ni-S) system at 20 GPa, the estimated pressure of the Martian core-mantle boundary (CMB), across its entire temperature range. Due to the fineness of quenched liquid features at high temperatures and low S concentrations, spatial analysis techniques, in additional to electron microprobe analysis, were used to determine the compositions of some quenched liquid phases. The maximum concentration of S in the Fe(Ni) solid is only 0.6 wt.%, comparable to the Fe-S binary system, but far lower than prior results for the Fe-Ni-S system at 20 GPa. We attribute this to the tendency of FeNi alloys to form body-centered cubic (BCC) structures when at high Ni contents, in contrast with face-centeredcubic (FCC) structures when Ni contents are low. Our liquidus curve is nearly ideal, featuring a maximum temperature depression of 80 C from 10 to 16 wt. % S, the likely range of Martian core composition. The slight negative departure from ideal behavior contrasts with the positive departure of liquidii previously applied to the Martian core without sufficient experimental constraints. Unlike existing liquidii at 23 GPa, which predict a fully molten core for a narrow range of sulfur content between 14 and 15 wt. % S, our result is consistent with a molten state for all proposed core compositions, and establishes a new minimum CMB temperature of 1200 C. Extrapolating our liquidus to high pressures and comparing it to calculated areotherms, we find that three core crystallization regimes are possible. For a Martian core with 10 to 12 wt. % S, crystallization takes the form of iron snow, while for cores with 13 to 16 wt. % S, solidification occurs near the center of the planet in the form of Fe3S crystallization. At 13 wt. % S, Fe3S would crystallize everywhere in the core, introducing a new scenario with uncertain and potentially interesting consequences for the Martian dynamo.

DEEP UNSUPERVISED DESPECKLING WITH UNBIASED RISK ESTIMATION
Publisher: name: IEEE Signal Processing Society
Year: 2025

description: Despeckling of Synthetic Aperture Radar (SAR) images has seen significant progress in recent years, largely driven by advancements in deep learning techniques. However, many of these approaches face challenges when applied to new SAR datasets, primarily due to their dependence on ground truth images, which are often unavailable for real-world sensors. In this paper, we address this limitation by extending the concept of unbiased risk estimation in the presence of Gamma-distributed multiplicative speckle. Specifically, we demonstrate that it is possible to train deep denoising networks without relying on ground truth data using our estimator. We introduce a new formulation of the Multiplicative Unbiased Risk Estimator (MURE) and present a computationally efficient Monte Carlo-based method that enables accurate estimation of the modified MURE cost, facilitating effective unsupervised training of deep neural networks from large datasets consisting solely of noisy SAR images. Experimental results on both synthetic datasets and real Sentinel-1 SAR images validate the suitability of our method for real-world applications. Even without ground truth, our method achieves performance that closely matches the Oracle-based denoiser and proves superior to the out-of-domain performance of popular supervised SAR despeckling methods. This supplementary material contains proof of some key results in the main paper.

description: The Pea Ridge (PR) deposit is one of several iron oxide deposits hosted by a sequence of 1.45-1.48 Ga rhyolite tuffs of the St. Francois Mountain terrane in southeastern Missouri, USA. The deposit is characterized dominantly by magnetite and overprinted by secondary hematite. There is no consensus on how the deposit formed, with working hypotheses that include circulating basinal brines, meteoric fluids, magmatic-hydrothermal fluids, and immiscible iron oxide melt. In this study, we quantified the abundances of Ti, V, Ca, Al, and Mn for three generations of magnetite at Pea Ridge. Type 1 contains ( 1 sigma) 8.41 1.24 wt. % Ti (range 5.7-12.4 wt. %), 790 360 ppm V (range 120-1400 ppm), 290 130 ppm Al (range 140-955 ppm), and 170 70 ppm Mn (range 80-430 ppm). Type 2 magnetite contains ( 1 sigma) 0.456 0.3 wt. % Ti (range 0.038-1.569 wt. %), 680 220 ppm V (range 280-1030 ppm), 444 500 ppm Al (range 130-2710 ppm) and 310 190 ppm Mn (range 80-640 ppm). Type 3, the modally dominant generation of magnetite, contains ( 1 sigma) 390 680 ppm Ti (range 60-6730 ppm), 486 130 ppm V (range 90-1070 ppm), 520 850 ppm Al (range 130-8980 ppm), and 440 150 ppm Mn (range 80-910 ppm). When plotted on the [Ca+Al+Mn] vs. [Ti+V] discriminant diagram, Type 1 magnetite is comparable to igneous magnetite, whereas Type 2 and Type 3 scatter across the BIF, IOCG, and Kiruna fields. It is important to note that the stable Fe and O isotope ratios for the same magnetite samples from Pea Ridge (i.e., aggregates of magnetite grains that include Types 1, 2 and 3) are unequivocally magmatic in origin. In this thesis, it is suggested that Type 1 magnetite represents the original magnetite mineralization, which retains the magmatic Fe- and O-isotope signatures, and that post-mineralization dissolution and reprecipitation resulted in Types 2 and 3 magnetite with lower Ti concentrations and wide scatter in V, Ca, Al, and Mn. Evidence for post-mineralized hydrothermal alteration is evinced by Oisotope data from zircon and quartz. The new data presented here support magmatic and magmatic-hydrothermal models for Pea Ridge.

description: The quasi-linear bands in the topologically trivial skutterudite insulator CoSb$_3$ are studied under adiabatic, symmetry-conserving displacement of the Sb sublattice. In this cubic, time-reversal and inversion symmetric system, a transition from trivial insulator to topological point Fermi surface system occurs through a critical point in which massless (Dirac) bands are {\it degenerate} with massive bands. Spin-orbit coupling does not alter the character of the transition. The mineral skutterudite (CoSb$_3$) is very near the critical point in its natural state.

description: Enhanced physical weathering rates in subglacial systems promote high levels of comminution, transport, and deposition of fine-grained sediment within the subglacial drainage network. The impact of shifts in sediment loads due to variations in meltwater flux, and their effects on downstream ecosystems, remains poorly quantified and places a fundamental importance on our ability to characterize subglacial depositional environments. Here, for the first time, we assess the seasonal evolution of the subglacial suspended sediment using coupled radiogenic strontium (87Sr/868 Sr) and neodymium (143Nd/1449 Nd) isotopic ratios with elemental ratios, and in-situ measurements. Weathering rates in fluvial and riverine systems have been traditionally assessed using radiogenic isotopic tracers: 143Nd/144Nd ratios relate to the crustal age whereas 87Sr/8611 Sr ratios relates to both age and preferential mineral dissolution. Relative shifts in these ratios allow us to characterize distinct sediment transport networks. We apply this technique to the Lemon Creek Glacier (LCG), Alaska, USA and the Athabasca Glacier (AG), Alberta, CA. At the LCG, the 143Nd/144Nd values range from εNd of -4.6 (0.9) to -8.7 (0.2), which suggests a poorly mixed sediment flux. However, the greatest period of variability may correlate with the drainage of a supraglacial lake and suggests caution should be exerted in timescale 143Nd/14418 Nd provenance studies that may be affected by climatic disturbances. In contrast, limited variation is observed within the AG 143Nd/14419 Nd seasonal record. A consistent, direct relation between the Rb/Sr elemental ratio and the 87Sr/8620 Sr ratio enables us to unravel incongruent weathering trends in the radiogenic Sr record. Correlation between the 87Sr/8622 Sr and total discharge suggests the process is partially controlled by mantling of the bedrock, which can be detected using post-comminution ages. While the subglacial structure may be enabled by the subglacial till beneath the AG, our study supports the use of Sr-Nd as a new proxy in the subglacial environment.

Our method involves development of a differential calculus of functions on the set of generalized Young diagrams.

description: We present clumps of dust emission from Herschel observations of the Large Magellanic Cloud (LMC) and their physical and statistical properties. We catalog cloud features seen in the dust emission from Herschel observations of the LMC, the Magellanic type irregular galaxy closest to the Milky Way, and compare these features with HI catalogs from the ATCA+Parkes HI survey. Using an automated cloud-finding algorithm, we identify clouds and clumps of dust emission and examine the cumulative mass distribution of the detected dust clouds. The mass of cold dust is determined from physical parameters that we derive by performing spectral energy distribution fits to 250, 350, and 500 micronm emission from SPIRE observations using DUSTY and GRASIL radiative transfer calculation with dust grain size distributions for graphite/silicate in low-metallicity extragalactic environments. The dust cloud mass spectrum follows a power law distribution with an exponent of gamma=-1.8 for clumps larger than 400 solar mass and is similar to the HI mass distribution. This is expected from the theory of ISM structure in the vicinity of star formation.

description: G54.1+0.3 is a Crab-like pulsar wind nebula (PWN) with the highest $γ$-ray to X-ray luminosity ratio among all the nebulae driven by young rotation-powered pulsars. We model the spectral evolution of the PWN and find it difficult to match the observed multi-band data with leptons alone using reasonable model parameters. In lepton-hadron hybrid model instead, TeV photons come mainly from $π^0$ decay in proton-proton interaction and the observed photon spectrum can be well reproduced. The newly discovered infrared loop and molecular cloud in or closely around the PWN can work as the target for the bombardment of the PWN protons.

description: In pervasive computing environments, Location- Based Services (LBSs) are becoming increasingly important due to continuous advances in mobile networks and positioning technologies. Nevertheless, the wide deployment of LBSs can jeopardize the location privacy of mobile users. Consequently, providing safeguards for location privacy of mobile users against being attacked is an important research issue. In this paper a new scheme for safeguarding location privacy is proposed. Our approach supports location K-anonymity for a wide range of mobile users with their own desired anonymity levels by clustering. The whole area of all users is divided into clusters recursively in order to get the Minimum Bounding Rectangle (MBR). The exact location information of a user is replaced by his MBR. Privacy analysis shows that our approach can achieve high resilience to location privacy threats and provide more privacy than users expect. Complexity analysis shows clusters can be adjusted in real time as mobile users join or leave. Moreover, the clustering algorithms possess strong robustness.

description: A formalism for the electromagnetic production of hypernuclei is developed where the cross section is written as a contraction between a leptonic tensor and a hadronic tensor. The hadronic tensor is written in a model-independent way by expanding it in terms of a set of five nuclear structure functions. These structure functions are calculated by assuming that the virtual photon interacts with only one bound nucleon. We use the most recent model for the elementary current operator which gives a good description of the experimental data for the corresponding elementary process. The bound state wave functions for the bound nucleon and hyperon are calculated within a relativistic mean-field model. We calculate the unpolarized triple differential cross section for the hypernuclear production process e + 12C --> e + K+ + 12_Lambda{B} as a function of the kaon scattering angle. The nuclear structure functions are calculated within a particle-hole model. The cross section displays a characteristic form of being large for small values of the kaon scattering angle with a smooth fall-off to zero with increasing angle. The shape of the cross section is essentially determined by the nuclear structure functions. In addition, it is found that for the unpolarized triple differential cross section one structure function is negligible over the entire range of the kaon scattering angle.

How bear lost his tail : an Indigenous perspective on inclusive deliberative democratic theory as applied to the Canadian societal context
Creators: name: Norris, Matthew
Publisher: name: University of British Columbia
Year: 2018

description: There exists a deep societal divide in Canada between Indigenous and settler societies. A divide which has continuously reared its head through demonstrations of violence, rage, or impassioned dismissal of the pursuit of justice for historical wrongs. As Indigenous voices for justice rise, Canada’s federal and provincial governments respond with policy and legislative change to address Indigenous unrest. Despite the introduction of numerous policies, legislation, and initiatives in an attempt to appease Indigenous voices, Canada has continuously failed to address the foundations of Indigenous calls for justice and has failed to address the disparities between Indigenous communities’ and non-Indigenous communities’ quality-of-life indicators, which in turn are a direct ramification of the injustices perpetuated against Indigenous peoples to which they demand recognition, recompense and reconciliation. When viewed through the lens of deliberative democratic theory the existence of deep societal division and the continual marginalization of particular social groups, appears counterintuitive when one considers the concentrated effort to promote their political inclusion, equality and publicity of Indigenous groups. In investigating this occurrence this thesis will conduct a review of Iris Marion Young’s model of deliberative democratic theory with a specific focus on Young’s four pillars of deliberative democratic theory for the pursuit of social justice, followed by an engagement with Frantz Fanon’s work on the psycho-afflictive disorders settler-colonial societies inflict and are reliant upon. By doing so this thesis will argue that settler colonialism creates, entrenches and makes invisible the systems which are responsible for the social delineations between us and them, between settler society and Indigenous societies, and between have and have nots. Further I argue that deliberative democratic theory, through its varied social justice mechanisms, is incapable of addressing the fundamental and structural mechanisms colonialism has created, which ensure the marginalization, disempowerment and dispossession of Indigenous peoples, systems on which the legitimacy of the colonial state relies. To overcome such shortfalls, Young’s pillar of ‘reasonableness’ must be actively pursued through a commitment and concrete action to unearth and challenge the foundations of settler-colonialism and to refute the divisionary policies on which the polity that is Canada has been built.

description: The Hirsch index (commonly referred to as h-index) is a bibliometric indicator which is widely recognized as effective for measuring the scientific production of a scholar since it summarizes size and impact of the research output. In a formal setting, the h-index is actually an empirical functional of the distribution of the citation counts received by the scholar. Under this approach, the asymptotic theory for the empirical h-index has been recently exploited when the citation counts follow a continuous distribution and, in particular, variance estimation has been considered for the Pareto-type and the Weibull-type distribution families. However, in bibliometric applications, citation counts display a distribution supported by the integers. Thus, we provide general properties for the empirical h-index under the small- and large-sample settings. In addition, we also introduce consistent nonparametric variance estimation, which allows for the implemention of large-sample set estimation for the theoretical h-index.

A general figure of merit for thick and thin transparent conductive carbon nanotube coatings

description: We suggest a wavelength-dependent figure of merit for transparent conducting nanotube networks, composed of the sheet resistance and the optical density. We argue that this would be more useful than other suggestions prevailing in the literature, because it relies on more realistic assumptions regarding the optical parameters of real nanotubes: it takes into account the fact that the dc resistivity depends on the concentration of free carriers, while the visible absorption is caused by bound carriers. Based on sheet resistance measurements and wide-range transmission spectra, we compare several commercial nanotube types and find correlation between metal enrichment and figure of merit. A simple graphical approach is suggested to determine if the required optical and transport properties can be achieved by varying the thickness of the nanotube layer or a more aggressive treatment is needed. The procedure can be extended to oxide coatings as well.

description: Low temperature magnetization M measurements down to 70~mK have been performed through the superconducting upper critical field H_c2 of CeCoIn5 with the field H parallel to the c axis of the tetragonal crystal. The crossing through the upper critical field H_c2(0) is marked by a sign change in the temperature dependence of M(T). A Fermi liquid law of the magnetization is observed in the superconducting phase while in the paramagnetic state above H_c2 a quasi-linear temperature dependence is obeyed. The specific heat below H_c2 is therefor dominated by the increase of γ(H), the linear term of the specific heat, and is marked by a singularity at H_{c2} (0). No indication of the so called Q-phase was observed below H_c2 (in contrast to the case with H applied in the basal plane).

description: Based on a new approximation method, namely pseudospectral method, a solution for the three order nonlinear ordinary differential laminar boundary layer Falkner-Skan equation has been obtained on the semi-infinite domain. The proposed approach is equipped by the orthogonal Hermite functions that have perfect properties to achieve this goal. This method solves the problem on the semi-infinite domain without truncating it to a finite domain and transforming domain of the problem to a finite domain. In addition, this method reduces solution of the problem to solution of a system of algebraic equations. We also present the comparison of this work with numerical results and show that the present method is applicable.

Diffusion with Stochastic Resetting

Publisher: name: arXiv
Year: 2011
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study simple diffusion where a particle stochastically resets to its initial position at a constant rate r. A finite resetting rate leads to a nonequilibrium stationary state with non-Gaussian fluctuations for the particle position. We also show that the mean time to find a stationary target by a diffusive searcher is finite and has a minimum value at an optimal resetting rate r^*. Resetting also alters fundamentally the late time decay of the survival probability of a stationary target when there are multiple searchers: while the typical survival probability decays exponentially with time, the average decays as a power law with an exponent depending continuously on the density of searchers.

The Horizon Europe CRM-geothermal project: Deliverable 3.4 - Report: Proof-of-concept oxalogenesis-oxalotrophy pathway for biorecovery of Li and Sr

description: In this report we present the data supporting the feasibility of implementing a pathway combining fungal oxalogenesis and bacterial oxalotrophy for the biorecovery of Li from deep geothermal fluids. While we provide data only for Li, we also provide a theoretical background on how Sr could be targeted using the same approach. The biorecovery approach consists of the following steps: 1) Oxalic acid (OA) production by a fungal strain, 2) Fluid filtration with oxalic acid in order to remove impurities such as Ca, and 3) Li immobilization as Li-carbonates via fluid alkalinization by bacterial oxalotrophy.

The data obtained under laboratory condition demonstrate the feasibility of the pathway. A strain of the fungus A. niger was able to produce OA at concentrations that are compatible with the next step in the pathway, i.e. at least 10 g/L. Fluid cleaning with OA in order to remove Ca (and other elements) via oxalate precipitation was possible for brines containing up to 54 g Ca/L which corresponds to the high salinity synthetic brine that the project partners agreed upon as experimental test solution. Finally, while actual Li2CO3 precipitation was not experimentally achieved yet, a simple geochemical model indicated that given a Li concentration of at least 400 ppm, Li2CO3 precipitation via oxalotrophy is theoretically possible. In addition, a sequential system has been proofed in order to allow the oxalotrophic bacteria to resume growth and alkalinize its medium.

As a result, in order to combine the three steps of the pathway at a pilot scale we propose to set up a sequential system. For this, further experiments will concentrate on optimizing OA production by our best OA producing strain A. niger, increasing Li concentration in the Ca-cleaned fluid via biosorption, and optimizing the stages of the sequential system in order to maximize Ca removal vs Li recovery as Li2CO3.

description: This paper aims to compare rational Chebyshev (RC) and Hermite functions (HF) collocation approach to solve the Volterra's model for population growth of a species within a closed system. This model is a nonlinear integro-differential equation where the integral term represents the effect of toxin. This approach is based on orthogonal functions which will be defined. The collocation method reduces the solution of this problem to the solution of a system of algebraic equations. We also compare these methods with some other numerical results and show that the present approach is applicable for solving nonlinear integro-differential equations.

Seismic velocity structure under Vancouver Island from travel time inversion : insight from Low Frequency Earthquakes
Creators: name: Savard, Geneviève
Publisher: name: University of British Columbia
Year: 2018

description: The Cascadia subduction zone is a warm subduction zone where Episodic Tremor and Slow Slip (ETS), a phenomenon with debated governing physical mechanisms, is observed. The eventual development of an accurate physical model of ETS relies on a comprehensive set of seismic and geodetic observations. Low Frequency Earthquakes (LFE) are one of the seismic signatures that accompany slow slip and possess discernible phase arrivals that can be used for traveltime inversion methods. I first address the issue of detecting LFEs by developing an automated algorithm that exploits cross-station waveform similarity. The algorithm detects thousands of events per ETS episode in southern Vancouver Island that reveal pronounced spatiotemporal clustering and complex propagation patterns that compare favourably with independent ob- servations in Cascadia. This method allows us to build a significantly improved catalogue of LFE templates that we next employed for local double-difference earthquake tomography with the aim of resolving structures in the vicinity of ETS and metamorphic controls on its generation. In southern Vancouver Island, tomographic images reveal high Poisson’s ratios associated with a dipping low‐velocity zone (LVZ) inferred to be overpressured, upper oceanic crust of the Juan de Fuca plate where LFEs and other slow‐slip phenomena occur. We also observe a low Poisson’s ratio anomaly ( ∼0.225) in the forearc continental crust above the mantle wedge coinciding with high Vp and high levels of clustered microseismicity. We develop a conceptual model where quartz concentration is produced by metasomatism in the forearc crust and catalyzed by a focussed ingress of slab-derived fluids at high pore pressure. In northern Vancouver Island, we also observe the LVZ and a low Poisson’s ratio anomaly in a similar position, but no associated microseismic activity. Distinct, parallel lineaments that trend slightly oblique to the strike of the megathrust are resolved within seismicity concentrations of the Nootka Fault Zone immediately offshore Nootka Island. We speculate that these features may represent faulting developed as a result of high strains associated with slab bending, amplified in the vicinity of the newly formed plate boundary. We also find possible evidence for a deep-seated, seismogenic fault near the Explorer Plate edge.

Los encapuchados se acercan desde varias direcciones. Meten cócteles molotov en los depósitos. Otros vigilan desde las calles cercanas, distribuidos en círculos concéntricos. La policía aparece una hora después. Detienen a dos jóvenes, hombre y mujer, que viven cerca de donde arde un camión. En la fachada del edificio, los encapuchados han escrito: LAS BRIGADAS PROSUBLIME SON DE TODOS Y NO SON DE NADIE. ESTÁN DESPUÉS DE IRSE" (comienzo del cuento).

description: We discuss the subject of Unextendible Product Bases with the orthogonality condition dropped and we prove that the lowest rank non-separable positive-partial-transpose states, i.e. states of rank 4 in 3 x 3 systems are always locally equivalent to a projection onto the orthogonal complement of a linear subspace spanned by an orthogonal Unextendible Product Basis. The product vectors in the kernels of the states belong to a non-zero measure subset of all general Unextendible Product Bases, nevertheless they can always be locally transformed to the orthogonal form. This fully confirms the surprising numerical results recently reported by Leinaas et al. Parts of the paper rely heavily on the use of Bezout's Theorem from algebraic geometry.

description: FEUTURE Working Paper

This Working Paper aims to embed FEUTURE’s analysis of drivers of EU-Turkey relations in a historical context. It does so by outlining and discussing several narratives which represent influential interpretations of EU-Turkey relations at different times in history. It is argued that narratives on EUTurkey relations became increasingly competitive in the course of time, both within EU and Turkey as well as between them. The paper maps these changes of narratives in light of different historical milestones and phases. The periodization also serves to outline trends of conflict, cooperation and convergence as manifested in the political discourse. Thereby, the paper also serves as starting point for the ensuing qualitative analysis of a vast set of sources, representing the debates in Turkey and the EU.
