Year: 2022

description: In our role as editors, in this introduction we draw on and extend the work of the historian Carlo Ginzburg (esp. 1980, 1989, 2013) to set out what we see as some of the main characteristics of investigative methods as a distinctive if heterogeneous field of research practices in their own right and explore their relevance in, to and for the social sciences. With reference to the ten contributions that make up the collection, we identify five such characteristics. As we perceive them, investigative methods have: 1. particularity, specificity or concreteness of focus; 2. the objects of investigation which provide that focus are typically unavailable to direct observation meaning investigations must take at least part of their lead from ‘trace’ data as a critical source of evidence that can be repurposed to access and reconstruct them indirectly; 3. that trace data acquires significance not on its own but by being linked to other data in bespoke evidentiary chains, catenaries or assemblages worked up as part of the investigation in question; 4. where the investigative targets are particularly complex, the process of data gathering, assessment and analysis is typically distributed and collaborative, something which demands its own methods; and 5. the ultimate aim is not just to know or understand the objects of investigation better, important as that is, but to intervene, whether by challenging an existing account or by opening up space for action on the issues the investigation has identified (something which itself can take many forms in relation to the contemporary politics of evidence). Based on this ideal-typical rendering of these practices, we argue the kinds of investigative methods detailed in our ten contributions can offer powerful contributions to contemporary research repertoires in the social sciences by offering a distinctive approach to knowledge making, increasingly through creative work with digital data and technologies that puts them to previously unanticipated ends.
A comparison of transpiration rates from three semi-arid tree species in response to partial stand clearing

Transpiration

description: As precipitation and temperature patterns continue to shift in response to climate change, total water availability including soil and surface waters are likewise altered. In central and west Texas, a common land management practice thought to increase surface water quantities and spring flow is the removal of Juniperus ashei commonly referred to as ashe juniper or cedar. Vegetative cover impacts the local water cycle through multiple feedback mechanisms including extraction of soil water by roots, and transpiration of water vapor back into the atmosphere. Through transpiration, plants exchange water for carbon from the atmosphere. This study aims to determine changes in transpiration rates pre- and post partial removal of ashe juniper (J. ashei) in a semi-arid forest located near Rocksprings, Texas using micrometeorological and sap flux data. We compared transpiration rates between three tree species - pinyon pine (Pinus remota), lacey oak (Quercus laceyi), and ashe juniper (J. ashei) under a variety of environmental conditions. Sap flow data revealed that ashe juniper used less water per day than the pines but more than the oaks. Transpiration rates increased after juniper removal with pines still transpiring the most water followed by juniper, and oaks using the least. Additionaly, it was found that pine trees located at lower elevations transpired more than individuals at higher elevations. By contrast, oak and juniper trees showed higher transpirations rates at higher elevations. An enhanced understanding of vegetation-climate interactions will provide key information for land management best practices to ensure resource resilience in the face of changing climate.
On Distributed Linear Estimation With Observation Model Uncertainties

description: We consider distributed estimation of a Gaussian source in a heterogenous bandwidth constrained sensor network, where the source is corrupted by independent multiplicative and additive observation noises, with incomplete statistical knowledge of the multiplicative noise. For multi-bit quantizers, we derive the closed-form mean-square-error (MSE) expression for the linear minimum MSE (LMMSE) estimator at the FC. For both error-free and erroneous communication channels, we propose several rate allocation methods named as longest root to leaf path, greedy and integer relaxation to (i) minimize the MSE given a network bandwidth constraint, and (ii) minimize the required network bandwidth given a target MSE. We also derive the Bayesian Cramer-Rao lower bound (CRLB) and compare the MSE performance of our proposed methods against the CRLB. Our results corroborate that, for low power multiplicative observation noises and adequate network bandwidth, the gaps between the MSE of our proposed methods and the CRLB are negligible, while the performance of other methods like individual rate allocation and uniform is not satisfactory.

description: The Doss-Sussmann (DS) approach is used for simulating the Cox-Ingersoll-Ross (CIR) process. The DS formalism allows for expressing trajectories of the CIR process by solutions of some ordinary differential equation (ODE) that depend on realizations of the Wiener process involved. Via simulating the first-passage times of the increments of the Wiener process to the boundary of an interval and solving an ODE, we approximately construct the trajectories of the CIR process. From a conceptual point of view the proposed method may be considered as an exact simulation approach.
Monte Carlo study of a superlattice mixed spins under a crystal and external magnetic fields

description: In this paper, we study the effect of both an external and crystal magnetic fields for a superlattice with mixed spins (1/2, 1), using Monte Carlo simulations. The ground state phase diagrams, in the external magnetic field, coupling constant and the crystal magnetic field planes, were established. The effect of increasing temperatures has also been established showing the behavior of the magnetizations and susceptibilities, for fixed crystal field values. In particular, the obtained results as well as in the ground state phase diagrams, as for non null temperature are obtained for fixed external magnetic and crystal field values. On the other hand, the effect of the temperature on the hysteresis loops is presented showing that the decreasing temperature effect is to increase the absolute values of the corresponding coercitif magnetic field.

A Look at What Is (and Isn't) Known About Quasar Broad Line Regions and How Narrow-Line Seyfert 1 Galaxies Fit In
Creators: name: Gaskell, C. Martin
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)

description: The evidence is reviewed that the Broad Line Region (BLR) probably has two distinct components located at about the same distance from the central black hole. One component, BLR II, is optically-thick, low-ionization emission at least some of which arises from a disc and the other, BLR I, is probably optically-thin emission from a more spherically symmetric halo or atmosphere. The high Fe II/H-beta ratios seen in Narrow-Line Seyfert 1 galaxies (NLS1s) are not due to strong Fe II emission, as is commonly thought, but to unusually weak Balmer emission, probably caused by higher densities. NLS1s probably differ from non-NLS1s because of the higher density of gas near the black hole. This produces a higher accretion rate, a denser BLR, and a view of the central regions that is more face-on.

Investigating the amplitude and rotation of the phase spiral in the Milky Way outer disc

description: Context: With the data releases from the astrometric space mission Gaia, the exploration of the structure of the Milky Way has developed in unprecedented detail and unveiled many previously unknown structures in the Galactic disc and halo. One such feature is the phase spiral where the stars in the Galactic disc form a spiral density pattern in the $Z-V_Z$ plane. Aims: We aim to characterize the shape, rotation, amplitude, and metallicity of the phase spiral in the outer disc of the Milky Way. This will allow us to better understand which physical processes caused the phase spiral and can give further clues to the Milky Way's past and the events that contributed to its current state. Methods: We use Gaia data release 3 (DR3) to get full position and velocity data on approximately 31.5 million stars, and metallicity for a subset of them. We then compute the angular momenta of the stars and develop a model to characterise the phase spiral in terms of amplitude and rotation at different locations in the disc. Results: We find that the rotation angle of the phase spiral changes with Galactic azimuth and Galactocentric radius, making the phase spiral appear to rotate about $3^\circ$ per degree in Galactic azimuth. Furthermore, we find that the phase spiral in the $2200 - 2400$ kpc km s$^{-1}$ range of angular momentum is particularly strong compared to the phase spiral that can be observed in the solar neighbourhood. The metallicity of the phase spiral appears to match that of the Milky Way disc field stars. Conclusions: We created a new model capable of fitting several key parameters of the phase spiral. We have been able to determine the rotation rate of the phase spiral and found a peak in the phase spiral amplitude which manifests as a very clear phase spiral when using only stars with similar angular momentum.

description: Starting from an innocent Ramsey-theoretic question regarding directed paths in tournaments, we discover a series of rich and surprising connections that lead into the theory around a fundamental problem in Combinatorics: the Ruzsa-Szemeredi induced matching problem. Using these relationships, we prove that every coloring of the edges of the transitive n-vertex tournament using three colors contains a directed path of length at least n−−√⋅elog∗n which entirely avoids some color. We also expose connections to a family of constructions for Ramsey tournaments, and introduce and resolve some natural generalizations of the Ruzsa-Szemeredi problem which we encounter through our investigation.
Intraseasonal Oscillation of Land Surface Moisture and its role in the maintenance of land ITCZ during the active phases of the Indian Summer Monsoon

description: What is the role of soil moisture in maintaining the land ITCZ during the active phase of the monsoon? This question has been addressed in this study by using ERA5 reanalysis datasets, and then we evaluate the question in the CFS model-free run. Like rainfall, soil moisture also show intraseasonal oscillation. Furthermore, the sub-seasonal and seasonal features of soil moisture are different from each other. During the summer monsoon season, the maximum soil moisture is found over western coastal regions, central parts of India, and the northeastern Indian subcontinent. However, during active phases of the monsoon, the maximum positive soil moisture anomaly was found in North West parts of India. soil moisture also play a pre-conditioning role during active phases of the monsoon over the monsoon core zone of India. When it is further divided into two boxes, the north monsoon core zone, and the south monsoon core zone, it is found that the preconditioning depends on that region's soil type and climate classification. Also, we calculate the moist static energy (MSE) budget during the monsoon phases to show how soil moisture feedback affects the boundary layer MSE and rainfall. A similar analysis is applied to the model run, but it cannot show the realistic preconditioning role of soil moisture and its feedback on the rainfall as in observations. We conclude that to get proper feedback between soil moisture and precipitation during the active phase of the monsoon in the model, the pre-conditioning of soil moisture should be realistic.
Containers of power : fibre forms from Northeast Arnhem Land Australia
Creators: name: Hamby, M Louise

Year: 2001

description: This thesis is a study of fibre container forms primarily made by women today in Arnhem Land. It investigates a complex set of relationships between the forms, mainly baskets, bags and mats, their makers and users, their functions, their morphology, their manufacture, and history. It does this within the cultural context of Yolηu cosmology with emphasis on the belief system and relationship of the forms to other items of material culture. Although the majority of the contemporary material for this study is from Gapuwiyak in eastern Arnhem Land it draws upon work from the entirety of Arnhem Land, historical and contemporary. My theoretical approach is one in which I consider these objects as having cultural biographies. It also examines the resonances of terminology and symbolism between the human and bathi corpus. In this context the processes that are involved in their making and use are essential in establishing the position of bathi in the community. In this thesis I argue that bathi are powerful and meaningful objects for makers and users and are one of the key means by which to access and understand Aboriginal cosmology from northeast Arnhem Land.
A numerical investigation of velocity-pressure reduced order models for incompressible flows

description: This report has two main goals. First, it numerically investigates three velocity-pressure reduced order models (ROMs) for incompressible flows. The proper orthogonal decomposition (POD) is used to generate the modes. One method computes the ROM pressure solely based on the velocity POD modes, whereas the other two ROMs use pressure modes as well. To the best of the authors' knowledge, one of the latter methods is novel. The second goal is to numerically investigate the impact of the snapshot accuracy on the ROMs accuracy. Numerical studies are performed on a two-dimensional laminar flow past a circular obstacle. It turns out that, both in terms of accuracy and efficiency, the two ROMs that utilize pressure modes are clearly superior to the ROM that uses only velocity modes. The numerical results also show a strong correlation of the accuracy of the snap shots with the accuracy of the ROMs.

description: The trace anomaly for a conformally invariant scalar field theory on a curved manifold of positive constant curvature with boundary is considered. In the context of a perturbative evaluation of the theory's effective action explicit calculations are given for those contributions to the conformal anomaly which emerge as a result of free scalar propagation as well as from scalar self-interactions up to second order in the scalar self-coupling. The renormalisation-group behaviour of the theory is, subsequently, exploited in order to advance the evaluation of the conformal anomaly to third order in the scalar self-coupling. In effect, complete contributions to the theory's conformal anomaly are evaluated up to fourth-loop order.

description: Excited states of a single donor in bulk silicon have previously been studied extensively based on effective mass theory. However, a proper theoretical description of the excited states of a donor cluster is still scarce. Here we study the excitations of lines of defects within a single-valley spherical band approximation, thus mapping the problem to a scaled hydrogen atom array. A series of detailed full configuration-interaction and time-dependent hybrid density-functional theory calculations have been performed to understand linear clusters of up to 10 donors. Our studies illustrate the generic features of their excited states, addressing the competition between formation of inter-donor ionic states and intra-donor atomic excited states. At short inter-donor distances, excited states of donor molecules are dominant, at intermediate distances ionic states play an important role, and at long distances the intra-donor excitations are predominant as expected. The calculations presented here emphasise the importance of correlations between donor electrons, and are thus complementary to other recent approaches that include effective mass anisotropy and multi-valley effects. The exchange splittings between relevant excited states have also been estimated for a donor pair and for a three-donor arrays; the splittings are much larger than those in the ground state in the range of donor separations between 10 and 20 nm. This establishes a solid theoretical basis for the use of excited-state exchange interactions for controllable quantum gate operations in silicon.

description: This note is devoted to the derivation of quantitative estimates for linear elliptic equations with coefficients that are not exactly ε-periodic and the ellipticity constant may degenerate for vanishing ε. Here ε>0 denotes the ratio between the microscopic and the macroscopic length scale. It is shown that for degenerating and non-degenerating coefficients the error between the original solution and the effective solution is of order √ε. Therefore suitable test functions are constructed via the periodic unfolding method and a gradient folding operator making only minimal additional assumptions on the given data and the effective solution with respect to the macroscopic scale.

This new class of problems is called as it singularly perturbed problems in case of exchange of stabilities. The main results are concerned with the asymptotic behavior of the solutions of initial value, boundary value and initial-boundary value problems as the perturbation parameter tends to zero. The report is based essentially on papers of the authors and their colleagues published in the last six to seven years in the frame of cooperation between the Department of Mathematics of the Faculty of Physics of the Lomonosov Moscow State University and the Department of Dynamical Systems of the Weierstrass Institute for Applied Analysis and Stochastics in Berlin.

description: In der vorliegenden Arbeit werden verschiedene Aspekte der Modellierung eines speziellen Biegetests von Gallium-Arsenid-Wafern diskutiert. Wafer sind dünne Kreisscheiben aus einkristallinem Material, aus denen in der Mikro- und Optoelektronikindustrie eingesetzt wird. Bei den hierzu notwendigen Herstellungsprozessen treten mechanische Beanspruchungen auf, die zum Bruch führen können. Der Biegetest dient dem Wafer-Hersteller zur Ermittlung der Bruchfestigkeit und zur Homogenitätsanalyse.
 In der Arbeit werden unter anderem experimentell gegebene Last-Durchbiegungskurven unter Verwendung der von Kármán'schen Plattentheorie numerisch mit hoher Genauigkeit verifiziert. Das Kontaktproblem, welches bei der Lastaufbringung mit einer Druckkugel entsteht, wird durch Hertz'sche Pressung modelliert. In diesem Zusammenhang werden insbesondere anisotrope Effekte untersucht. Es werden numerisch berechnete isotrope Ersatzkonstanten zur Lösung des elastischen Biegeproblems angegeben, die sich nicht aus einer klassischen Mittelungstheorie, z.B. nach Voigt oder Reuss, herleiten lassen. Die von Kármán'sche Theorie wird zuerst auf klassischem Wege durch Formulierung bestimmter Kleinheitsannahmen aus dem 3D-Problem hergeleitet. Diese Annahmen werden anschließend durch formal asymptotische Entwicklung der Verschiebungen gerechtfertigt. Die numerische Umsetzung des Biegeproblems wird mit Hilfe von reduzierten Hermite-Dreieckselementen realisiert. Das resultierende nichtlineare Finite-Element-Schema wird vollständig beschrieben. Dabei wird bei der Formulierung der Randbedingungen auf dem frei drehbaren Stützrand dem Babuska-Plattenparadox Rechnung getragen, so dass hier trotz Verwendung geradliniger Plattenelemente zur Approximation eines krummlinigen Stützrandes Konvergenz erreicht wird.
 Die numerischen Untersuchungen zeigen, dass in der Umgebung der Kontaktfläche, die unter der Druckkugel entsteht, die Voraussetzungen zur Gültigkeit der Plattentheorie verletzt sind. Deshalb werden am Schluss der Arbeit analytische Lösungen für den isotropen linearen Fall nach der 2D-Theorie gemäß Kirchhoff und der 3D-Theorie für dicke Platten unter Verwendung der Ansätze von Papkowitsch und Neuber verglichen. Insbesondere wird die Größe des Fehlers der berechneten Maximalspannungen in Abhängigkeit vom Kontaktradius bei Verwendung einer 2D-Theorie untersucht.

description: This paper discloses the results of a geologic investigation of an area lying on the south rim of the Llano basin. A map is presented showing the stratigraphy and structure of this area. The historical events of the region were deformation and igneous intrusion antedating Upper Cambrian, doming in Paleozoic time, and faulting in or preceding Strawn time. The major faults trend northeast-southwest. The formations represented are the Edwards, Comanche Peak, and Basement Sands of the Cretaceous; the Cap Mountain and Hickory of Upper Cambrian age; and granites and metamorphics of pre-Cambrian age. Although stock raising and farming are the principal sources of income, the region is potentially rich in building material and minerals. An excellent climate, a sufficient annual rainfall, and a scenic panorama make this part of the "hill country" exceedingly livable

description: We study a restricted class of self-avoiding walks (SAW) which start at the origin (0, 0), end at $(L, L)$, and are entirely contained in the square $[0, L] \times [0, L]$ on the square lattice ${\mathbb Z}^2$. The number of distinct walks is known to grow as $λ^{L^2+o(L^2)}$. We estimate $λ= 1.744550 \pm 0.000005$ as well as obtaining strict upper and lower bounds, $1.628 < λ< 1.782.$ We give exact results for the number of SAW of length $2L + 2K$ for $K = 0, 1, 2$ and asymptotic results for $K = o(L^{1/3})$. We also consider the model in which a weight or {\em fugacity} $x$ is associated with each step of the walk. This gives rise to a canonical model of a phase transition. For $x < 1/μ$ the average length of a SAW grows as $L$, while for $x > 1/μ$ it grows as $L^2$. Here $μ$ is the growth constant of unconstrained SAW in ${\mathbb Z}^2$. For $x = 1/μ$ we provide numerical evidence, but no proof, that the average walk length grows as $L^{4/3}$. We also consider Hamiltonian walks under the same restriction. They are known to grow as $τ^{L^2+o(L^2)}$ on the same $L \times L$ lattice. We give precise estimates for $τ$ as well as upper and lower bounds, and prove that $τ< λ.$

Electromagnetic Gauge Invariance of Chiral Hybrid Quark Models

description: In this work, we investigate the question, whether the conventional analysis of the electromagnetic form factors of the nucleon, evaluated in the framework of the cloudy bag model (CBM) or other chirally invariant hybrid quark models utilizing the same philosophy, is gauge invariant. In order to address that point, we first formulate the CBM in a style that resembles the technique of loop integrals. Evaluating the self energy and the electromagnetic form factors of the nucleon in that manner and comparing with the standard analysis where nonrelativistic perturbation theory is used, allows us to show that our approach is appropriate and to point out, what approximations are made in the standard derivation of the model. {}From the form of those loop integrals, we then show that additional diagrams are needed to preserve electromagnetic gauge invariance and we assess the corresponding corrections.

description: The chemical potential u of an electron system is a fundamental property of a solid. A precise measurement of u plays a crucial role in understanding the electron interaction and quantum states of matter. However, thermodynamics measurements in micro and nanoscale samples are challenging because of the small sample volume and large background signals. Here, we report an optical readout technique for u of an arbitrary two-dimensional (2D) material. A monolayer semiconductor sensor is capacitively coupled to the sample. The sensor optical response determines a bias that fixes its chemical potential to the band edge and directly reads u of the sample. We demonstrate the technique in AB-stacked MoTe2/WSe2 moire bilayers. We obtain u with DC sensitivity about 20 ueV/sqrt(Hz), and the compressibility and interlayer electric polarization using AC readout. The results reveal a correlated insulating state at the doping density of one hole per moire unit cell, which evolves from a Mott to a charge-transfer insulator with increasing out-of-plane electric field. Furthermore, we image u and quantify the spatial inhomogeneity of the sample. Our work opens the door for high spatial and temporal resolution measurements of the thermodynamic properties of 2D quantum materials.

The infrared luminosities and temperatures, opacities and sizes of the emitting dust components are derived. A comparison between the observed infrared spectra and the optical emission line fluxes of a sample of 16 NLS1 galaxies suggests that these objects suffer different degrees of dust absorption according to the inclination of the line of sight with respect to the dust distribution.

description: The pion - nucleon scattering phase shifts in $s$ and $p$ waves are analyzed using PKU unitarization approach that can separate the phase shifts into different contributions from poles and branch cuts. It is found that in $S_{11}$ and $P_{11}$ channels, there exist large and positive missing contributions when one compares the phase shift from known resonances plus branch cuts with the experimental data, which indicates that those two channels may contain sizable effects from $N^*(1535)$ and $N^*(1440)$ shadow poles. Those results are obtained using tree level results of the $πN$ amplitude.

description: A graph is called diameter-k-critical if its diameter is k, and the removal of any edge strictly increases the diameter. In this paper, we prove several results related to a conjecture often attributed to Murty and Simon, regarding the maximum number of edges that any diameter-k-critical graph can have. In particular, we disprove a longstanding conjecture of Caccetta and H¨aggkvist (that in every diameter-2-critical graph, the average edge-degree is at most the number of vertices), which promised to completely solve the extremal problem for diameter-2-critical graphs. On the other hand, we prove that the same claim holds for all higher diameters, and is asymptotically tight, resolving the average edge-degree question in all cases except diameter-2. We also apply our techniques to prove several bounds for the original extremal question, including the correct asymptotic bound for diameter-k-critical graphs, and an upper bound of ( 1/6 +o(1))n2 for the number of edges in a diameter-3-critical graph.

description: In the field of Sequential Decision Making (SDM), two paradigms have historically vied for supremacy: Automated Planning (AP) and Reinforcement Learning (RL). In the spirit of reconciliation, this article reviews AP, RL and hybrid methods (e.g., novel learn to plan techniques) for solving Sequential Decision Processes (SDPs), focusing on their knowledge representation: symbolic, subsymbolic, or a combination. Additionally, it also covers methods for learning the SDP structure. Finally, we compare the advantages and drawbacks of the existing methods and conclude that neurosymbolic AI poses a promising approach for SDM, since it combines AP and RL with a hybrid knowledge representation.

description: An oscillatory pattern in the smoothed quantum spectrum, which is unique for single-particle motions in a reflection-asymmetric superdeformed oscillator potential, is investigated by means of the semiclassical theory of shell structure. Clear correspondence between the oscillating components of the smoothed level density and the classical periodic orbits is found. It is shown that an interference effect between two families of the short periodic orbits, called supershell effect, develops with increasing reflection-asymmetric deformations. Possible origins of this enhancement phenomena as well as quantum signatures of period-multipling bifurcations are discussed in connection with stabilities of the classical periodic orbits.

The Analytic Bootstrap in Fermionic CFTs

description: We apply the method of the large spin bootstrap to analyse fermionic conformal field theories with weakly broken higher spin symmetry. Through the study of correlators of composite operators, we find the anomalous dimensions and OPE coefficients in the Gross-Neveu model in $d=2+\varepsilon$ dimensions and the Gross-Neveu-Yukawa model in $d=4-\varepsilon$ dimensions, based only on crossing symmetry. Furthermore a non-trivial solution in the $d=2+\varepsilon$ expansion is found for a fermionic theory in which the fundamental field is not part of the spectrum. The results are perturbative in $\varepsilon$ and valid to all orders in the spin, reproducing known results for operator dimensions and providing some new results for operator dimensions and OPE coefficients.

description: Text Classification is the most essential and fundamental problem in Natural Language Processing. While numerous recent text classification models applied the sequential deep learning technique, graph neural network-based models can directly deal with complex structured text data and exploit global information. Many real text classification applications can be naturally cast into a graph, which captures words, documents, and corpus global features. In this survey, we bring the coverage of methods up to 2023, including corpus-level and document-level graph neural networks. We discuss each of these methods in detail, dealing with the graph construction mechanisms and the graph-based learning process. As well as the technological survey, we look at issues behind and future directions addressed in text classification using graph neural networks. We also cover datasets, evaluation metrics, and experiment design and present a summary of published performance on the publicly available benchmarks. Note that we present a comprehensive comparison between different techniques and identify the pros and cons of various evaluation metrics in this survey.

description: For more than twenty years, strong Fe II emission lines have been observed in Active Galactic Nuclei and in particular in Narrow Line Seyfert 1 galaxies. A quick overview of the observations and of the models proposed to interpret the Fe II spectrum is given. The influence of atomic data and of physical parameters are discussed, and it is shown that the strengths of the Fe II lines cannot be explained in the framework of photoionization models. A non-radiative heating, for instance due to shocks, with an overabundance of iron, can help to solve the problem. A comparison with other objects emitting intense Fe II lines favors also the presence of strong outflows and shocks. We suggest some issues in the context of AGN evolution.

description: It is a well-known phenomenon in set theory that problems in in- finite combinatorics involving singular cardinals and their successors tend to be harder than the parallel problems for regular cardinals. Examples include the behaviour of cardinal exponentiation, the extent of the tree property, the extent of stationary reflection, and the existence of non-free almost-free abelian groups. The explanation for this phenomenon lies in inner model theory, in particular core models and covering lemmas.

description: In this article, we derive conditions for the existence of solutions to state-constrained continuity inclusions in Wasserstein spaces whose right-hand sides may be discontinuous in time. These latter are based on a fine investigation of the infinitesimal behaviour of the underlying reachable sets, through which we show that up to a negligible set of times, every admissible velocity of a continuity inclusion can be approximately realised as the metric derivative of a solution of the dynamics, and vice versa. Building on these results, we are able to establish necessary and sufficient geometric conditions for the viability and invariance of stationary and time-dependent constraint sets which involve a suitable notion of contingent cones in Wasserstein spaces, and presented in ascending order of generality. We then close the article by exhibiting two prototypical examples of constraints sets appearing in applications for which one can compute relevant subfamilies of contingent directions.

description: Next generation surveys will provide us with an unprecedented number of detections of supernovae Type Ia and gravitational wave merger events. Cross-correlations of such objects offer novel and powerful insights into the large-scale distribution of matter in the universe. Both of these sources carry information on their luminosity distance, but remain uninformative about their redshifts; hence their clustering analyses and cross-correlations need to be carried out in luminosity distance space, as opposed to redshift space. In this paper, we calculate the full expression for the number count fluctuation in terms of a perturbation to the observed luminosity distance. We find the expression to differ significantly from the one commonly used in redshift space. Furthermore, we present a comparison of the number count angular power spectra between luminosity distance and redshift spaces. We see a wide divergence between the two at large scales, and we note that lensing is the main contribution to such differences. On such scales and at higher redshifts the difference between the angular power spectra in luminosity distance and redshift spaces can be roughly 50$\%$. We also investigate cross-correlating different redshift bins using different tracers, i.e. one in luminosity distance space and one in redshift, simulating the cross-correlation angular power spectrum between background gravitational waves/supernovae and foreground galaxies. Finally, we show that in a cosmic variance limited survey, the relativistic corrections to the density-only term ought to be included.

description: It is proposed a simple non linear incremental modelling of the axi-symmetric compression of granular materials and powders. It describes the main features of undrained compression and of oedometric compression using the results of compression tests at constant lateral stress . It generalises the concept of characteristic state. It shows that trajectories arriving at a given critical state shall pertain to a single surface in the (v,q,p) space, which confirms the recent result demonstrating that Hvorslev's and Roscoe's surfaces are part of the same surface. Effects of induced anisotropy are discussed; comparison with classical camclay model is performed.
