description: The Large Survey of Space and Time (LSST) will start to carry out a massive survey which will provide data with statistical errors below the systematic uncertainty due to photometric calibration. With the massive number of objects that it will observe, the statistical errors will shrink, making systematic effects the main source of uncertainty. In this regard, measuring colours and calibrating them will be a crucial task for LSST and similar photometric cosmological surveys in their way to obtain reliable cosmological measurements. This is particularly important for obtaining cosmological information from supernovae and to compute photometric redshifts. One of the main sources of photometric uncertainty is associated with the variations on instrumental and atmospheric transmission. To deal with atmospheric effects, LSST counts with a companion telescope, the Auxiliary Telescope (AuxTel), whose purpose is to measure the atmospheric transparency and to derive colour corrections based on spectroscopic observations. In this contribution we will go through the latest improvements that we carried out on AuxTel during September 2023, the methodologies that we are developing to correct for systematic effects on its focal surface and to properly extract spectra and the progress made on our method to derive colour compensations from spectra taken with AuxTel to be applied to LSST’s photometry. This way, we aim to ensure uniformity across the sky and repeatability of the measurements across the 10 years of survey.

description: New line lists are presented for the two most abundant water isotopologues; H$_{2}$$^{16}$O and H$_{2}$$^{18}$O. The H$_{2}$$^{16}$O line list extends to 25710 cm$^{-1}$ with intensity stabilities provided via ratios of calculated intensities obtained from two different semi-empirical potential energy surfaces. The line list for H$_{2}$$^{18}$O extends to 20000 cm$^{-1}$. The minimum intensity considered for all is $10^{-30}$ cm molecule$^{-1}$ at 296~K, assuming 100\% abundance for each isotopologue. Fluctuation of calculated intensities caused by changes in the underlying potential energy are found to be significant, particularly for weak transitions. Direct comparisons are made against eighteen different sources of line intensities, both experimental and theoretical, many of which are used within the HITRAN2016 database. With some exceptions, there is excellent agreement between our line lists and the experimental intensities in HITRAN2016. In the infrared region, many H$_{2}$$^{16}$O bands which exhibit intensity differences of 5-10\% between to the most recent 'POKAZATEL' line list (Polyansky \textit{et al.}, [Mon. Not. Roy. Astron. Soc. \textbf{480}, 2597 (2018)] and observation, are now generally predicted to within 1\%. For H$_{2}$$^{18}$O, there are systematic differences in the strongest intensities calculated in this work versus those obtained from semi-empirical calculations. In the visible, computed cross sections show smaller residuals between our work and both HITRAN2016 and HITEMP2010 than POKAZATEL. While our line list accurately reproduces HITEMP2010 cross sections in the observed region, residuals produced from this comparison do however highlight the need to update line positions in the visible spectrum of HITEMP2010. These line lists will be used to update many transition intensities and line positions in the HITRAN2016 database.

In the breached pairing color superconducting phase heavy $s$-quarks, with a small Fermi surface, pair with light $u$ or $d$ quarks. The groundstate has a superfluid and a normal Fermi component simultaneously. We expect a second order phase transition, as a function of increasing density, from the breached pairing phase to the conventional color-flavor locked (CFL) phase.

description: We examine the ability of a target zone to stabilize exchange rates in the presence of two stylised forms of market inefficiency - stochastic bubbles and "fads". We show how the usual saddlepath phase diagram is modified in the presence of bubbles (both where fundamentals are deterministic and where they are stochastic), and how a credible policy to defend a target zone prevents the emergence of any such bubbles. In the case of fads, we suppose that the source of shocks driving the exchange rate from its long-run equilibrium level is the fluctuating sentiment of "noise traders". The presence of "smart money" in the market exerts a stabilizing influence upon the exchange rate even in the absence of a target zone. In the presence of a fully credible target zone, where the authorities can take the necessary actions to check the swings in market sentiment, we use results on regulated Brownian motion to characterise the exchange rate trajectory, and demonstrate that the stabilizing influence of "smart money" is increased.

description: The paper examines official Soviet estimates of the change in total output and output per worker in Soviet industry during World War II. These are shown to have understated wartime industrial performance by a significant margin. New estimates of industrial production, labour inputs and productivity are put forward. The likely contribution to maintenance of total output and labour productivity arising from the rapid structural change in favour of munitions work is also assessed. While output per hour worked in munitions branches of industry grew rapidly, the productivity of labour in civilian branches may have deteriorated before recovering to prewar levels in 1944.

description: Face à une urbanisation rapide qui soulève des enjeux complexes de gestion et de développement durable, les villes explorent continuellement des méthodes innovantes pour impliquer efficacement leurs citoyens dans les décisions qui les concernent. Toutefois, les méthodes participatives actuelles se révèlent souvent inefficaces, limitant la portée et l’efficacité de l’engagement citoyen. L’intégration de l’intelligence artificielle (IA) et du métavers dans ces processus peut ouvrir à de nouvelles perspectives : elle offre une opportunité unique de repenser la façon dont les citoyens et les pouvoirs publics fabriquent la Ville, la perçoivent, la conçoivent et la vivent.Cependant, il est crucial de reconnaître et de s’attaquer à la fracture numérique qui pourrait restreindre l’accès à ces technologies innovantes pour certaines parties de la population.

description: This paper presents a new measure of the real national income of the Soviet Union on the eve of World Mar II and during the war years. The new measure is compared with existing official and independent estimates. The heavy weight of the wartime Soviet defence burden is confirmed by the standards both of peace time and of other powers engaged in World War II. The Soviet commitment of labour resources to the war was also very heavy, but does not seem so impressive by international wartime standards. This reflects, in part, a real underlying constraint on Soviet wartime mobilisation rooted in the labour requirements of a large, low productivity agricultural sector.

description: We derive a new microscopic spin Hamiltonian for Rashba-coupled double exchange metals. The Hamiltonian consists of anisotropic interactions of the Dzyaloshinskii-Moriya (DM) and Kitaev form, in addition to the standard isotropic term. We validate the spin Hamiltonian by comparing results with those on the exact spin-fermion model, and present its phase diagram using large scale Monte Carlo simulations. In addition to ferromagnetic, planar spiral and flux states, the model hosts skyrmion crystal and classical spin-liquid states characterized, respectively, by multiple peaks and a diffuse ring pattern in the spin structure factor. The filamentary domain wall structures in the spin-liquid state are in remarkable agreement with experimental data on thin films of MnSi-type B20 metals and transition metals and their alloys.

title: Fully isogeometric modeling and analysis of nonlinear 3D beams with spatially varying geometric and material parameters
Creators: name: Weeger, Oliver
name: Yeung, Sai-Kit
name: Dunn, Martin L.
Publisher: name: Elsevier
Year: 2022

description: We present a fully isogeometric modeling and simulation method for geometrically exact, nonlinear 3D beams with spatially varying geometric and material distributions, both along the beam axis and through its cross-section. The approach is based on the modeling of 3D beams using the Cosserat rod theory and the numerical discretization using B-Spline and NURBS parameterizations in an isogeometric collocation method. Transversally varying material constitutions are represented using non-homogeneous, functionally graded beam cross-section definitions such as laminates and continuously graded cross-sections. Furthermore, to model the axial variation of material and geometry, we introduce the parameterization of cross-section properties as spline curves along the beam centerlines. This fully isogeometric modeling and analysis concept, which is based on spline parameterizations of initial beam centerline curves, kinematic unknowns and axially varying material and geometric parameters, has various practical applications enabled by advances in manufacturing technology, including multi-material 3D printing and advanced manufacturing of composites with automated fiber placement. We verify and demonstrate the modeling and simulation approach using several numerical studies and highlight its practical applicability.

Power Spectrum of Cosmic Momentum Field Measured from the SFI Galaxy Sample

description: We have measured the cosmic momentum power spectrum from the peculiar velocities of galaxies in the SFI sample. The SFI catalog contains field spiral galaxies with radial peculiar velocities derived from the I-band Tully-Fisher relation. As a natural measure of the large-scale peculiar velocity field, we use the cosmic momentum field that is defined as the peculiar velocity field weighted by local number of galaxies. We have shown that the momentum power spectrum can be derived from the density power spectrum for the constant linear biasing of galaxy formation, which makes it possible to estimate β_S = Ω_m^{0.6} / b_S parameter precisely where Ω_m is the matter density parameter and b_S is the bias factor for optical spiral galaxies. At each wavenumber k we estimate β_S(k) as the ratio of the measured to the derived momentum power over a wide range of scales (0.026 h^{-1}Mpc

description: It is pointed out that the dynamics of the order parameter at a thermal critical point obeys the precepts of the nonextensive Tsallis statistics. We arrive at this conclusion by putting together two well-defined statistical-mechanical developments. The first is that critical fluctuations are correctly described by the dynamics of an intermittent nonlinear map. The second is that intermittency in the neighborhood of a tangent bifurcation in such map rigorously obeys nonextensive statistics. We comment on the implications of this result. Key words: critical fluctuations, intermittency, nonextensive statistics, anomalous stationary states

description: Coupled micro- and nanomechanical resonators are of significant interest within a number of areas of research, ranging from synchronisation, nonlinear dynamics and chaos, to quantum sensing and transduction. Building upon our work on soft-clamped membrane resonators, here we present a study on phononic dimers, consisting of two defects embedded in a phononic crystal membrane. These devices exhibit widely tunable (2-100 kHz) inter-defect coupling strengths, leading to delocalized hybrid modes with mechanical Qf-products > 10^14 Hz at room temperature,ensuring low thermomechanical force noise. The mode splitting exhibits a strong dependence on the dimer orientation within the crystal lattice, as well as the spatial separation between the two defects. Given the importance of dynamic range for sensing applications, we characterize the relevant mechanical nonlinearities, specifically the self- and cross-Duffing parameters, as well as self and cross-nonlinear dampings. This work establishes soft-clamped resonators with engineered spatial and spectral multi-mode structure as a versatile mechanical platform both in the classical and quantum regimes. Applications in microwave-to-optical transduction and magnetic resonance force microscopy are particularly attractive prospects.
title: Multiculture, Community and Social Inclusion in New City Spaces
Creators: name: Kesten, Jamie
Publisher: name: The Open University
Year: 2012

description: This thesis is interested in understanding the new migration patterns and changing geographies of multiculture taking place in the UK outside of the larger established cities and towns by investigating Milton Keynes (MK) as a new multicultural city space. Using a case study of MK's Ghanaian and Somali communities it explores how BME communities establish themselves as part of the wider local community and examines the ways in which local policy-makers and practitioners have responded to an increasingly multicultural and ethnically diverse population. The research focuses upon local sites of community construction such as schools, provision for young people and religious centres, reflecting, among other things, the particular formal and informal roles played by these sites. The thesis finds that people within MK are not living the 'parallel lives' crisis of the community cohesion discourse, but rather 'living apart' at times and also 'living together' at others, reinforcing the significance of place-based understandings in the context of new multicultural geographies. The research found that young people of Ghanaian and Somali origin often reflected positively on the sense of community present within MK's residential areas and demonstrated processes of negotiation and of both 'mixing' and 'non-mixing' within certain distinct social and geographic contexts. It also found that, in seeking to manage the emergent multicultural population, policy-makers and practitioners generally rely on identifying community organisations (and their leaders) with whom they can liaise. In doing so they may overlook the significant diversity of experiences which exist within the Ghanaian and Somali communities (and the extent to which these are subject to change) and are therefore less likely to deliver appropriate resources and interventions. The research findings indicated that how people themselves manage multiculture is much more fluid and able to be negotiated than cohesion discourses and formal policy makers imagine and assume.

description: We study the effect of electric charge in compact stars assuming that the charge distribution is proportional to the mass density. The pressure and the density of the matter inside the stars are large, and the gravitational field is intense. This indicates that electric charge and a strong electric field can also be present. The relativistic hydrostatic equilibrium equation, i.e., the Tolman-Oppenheimer-Volkoff equation, is modified in order to include electric charge. We perform a detailed numerical study of the effect of electric charge using a polytropic equation of state. We conclude that in order to see any appreciable effect on the phenomenology of the compact stars, the electric fields have to be huge (~ 10^{21} V/m), which implies that the total charge is Q ~ 10^{20} Coulomb. From the local effect of the forces experienced on a single charged particle, it is expected that each individual charged particle is quickly ejected from the star. This in turn produces a huge force imbalance, and the gravitational force overwhelms the repulsive Coulomb and fluid pressure forces. The star can then collapse to form a charged black hole before all the charge leaves the system.

description: A system of Boundary-Domain Integral Equations is derived from the mixed (Dirichlet-Neumann) boundary value problem for the diffusion equation in inhomogeneous media defined on an unbounded domain. Boundary-domain integral equations are formulated in terms of parametrix-based potential type integral operators defined on the boundary and the domain. Mapping properties of parametrix-based potentials on weighted Sobolev spaces are analysed. Equivalence between the original boundary value problem and the system of BDIEs is shown. Uniqueness of solution of the BDIEs is proved using Fredholm Alternative and compactness arguments adapted to weigthed Sobolev spaces.

description: Only one certain classical nova eruption has ever been detected inside a globular cluster - nova 1860 A.D. (T Sco) in M80. During a survey of M87 we have detected an erupting star coincident (to within 0.08 pixels) with a globular cluster of that giant elliptical galaxy. We are able to discount variables in the foreground or background of M87. The light curve and color of the erupting star match those expected for a nova at the distance of M87. The chance superposition of an M87 field nova on the globular cluster is very unlikely but cannot be completely ruled out.Our detection hints at a globular cluster nova frequency $f \sim .004$ novae/cluster/year, much higher than previous observations have suggested.

description: This paper examines the circumstances which enable trade unions to establish wage differentials. Union wage differentials are created by the capturing of rents and the paper considers the circumstances in which rents exist to be captured and when unions are able to do so. In line with theoretical predictions, differentials are found to be very different in establishments facing competitive product market conditions and in those with some degree of product market power. In the former, high union coverage of the industry and the union strength given by a pre-entry closed shop are found to be dominant requirements, with only a very small minority of establishments satisfying even these. In contrast there is found to be considerably greater scope for unions in firms with market power and neither of the above conditions are a requirement for the existence of a differential in this case. Unions are found to be unable to create differentials in establishments which operate primarily in international markets.

description: The discovery that at least some Fast Radio Bursts (FRBs) repeat has ruled out cataclysmic events as the progenitors of these particular bursts. FRB~121102 is the most well-studied repeating FRB but despite extensive monitoring of the source, no underlying pattern in the repetition has previously been identified. Here, we present the results from a radio monitoring campaign of FRB~121102 using the 76-m Lovell telescope. Using the pulses detected in the Lovell data along with pulses from the literature, we report a detection of periodic behaviour of the source over the span of five years of data. We predict that the source is currently `off' and that it should turn `on' for the approximate MJD range $59002-59089$ (2020-06-02 to 2020-08-28). This result, along with the recent detection of periodicity from another repeating FRB, highlights the need for long-term monitoring of repeating FRBs at a high cadence. Using simulations, we show that one needs at least 100 hours of telescope time to follow-up repeating FRBs at a cadence of 0.5--3 days to detect periodicities in the range of 10--150 days. If the period is real, it shows that repeating FRBs can have a large range in their activity periods that might be difficult to reconcile with neutron star precession models.

description: The critical behavior of the three-dimensional $N$-vector chiral model is studied for arbitrary $N$. The known six-loop renormalization-group (RG) expansions are resummed using the Borel transformation combined with the conformal mapping and Padé approximant techniques. Analyzing the fixed point location and the structure of RG flows, it is found that two marginal values of $N$ exist which separate domains of continuous chiral phase transitions $N > N_{c1}$ and $N < N_{c2}$ from the region $N_{c1} > N > N_{c2}$ where such transitions are first-order. Our calculations yield $N_{c1} = 6.4(4)$ and $N_{c2} = 5.7(3)$. For $N > N_{c1}$ the structure of RG flows is identical to that given by the $ε$ and 1/N expansions with the chiral fixed point being a stable node. For $N < N_{c2}$ the chiral fixed point turns out to be a focus having no generic relation to the stable fixed point seen at small $ε$ and large $N$. In this domain, containing the physical values $N = 2$ and $N = 3$, phase trajectories approach the fixed point in a spiral-like manner giving rise to unusual crossover regimes which may imitate varying (scattered) critical exponents seen in numerous physical and computer experiments.

On the Asymptotic Completeness of the Volterra Calculus
Creators: name: Ponge, Raphael
Publisher: name: arXiv

Subjects: subject: Analysis of PDEs (math.AP)

subject: Primary 35S05

description: The Volterra calculus is a simple and powerful pseudodifferential tool for inverting parabolic equations and it has also found many applications in geometric analysis. On the other hand, an important property in the theory of pseudodifferential operators is the asymptotic completeness, which allows us to construct parametrices modulo smoothing operators. In this paper we present new and fairly elementary proofs the asymptotic completeness of the Volterra calculus.

description: In this paper we investigate the relationship between within-period preferences and the degree of intertemporal substitution. We first present a theoretical discussion which argues that the form of within-period preferences and the way these differ across consumers may have important consequences for the formulation and specification of intertemporal models. We then apply this methodology to a detailed study of disaggregate household expenditure patterns using a pooled cross-section of some 70,000 households across 15 years. Our objective is to assess the degree of intertemporal substitution across different household types avoiding aggregation bias and accounting for nonadditive within-period preferences and nonlinearity in Engel curves.

description: We introduce the framework of parameterized collections of games with and without sidepayments and provide three nonemptiness of approximate core theorems for games in parameterized collections. The parameters bound (a) the number of approximate types of players and the size of the approximation and (b) the size of nearly e®ective groups of players and their distance from exact e®ectiveness. The theorems are based on a new notion of partition-balanced pro¯les and approximately partition-balanced pro¯les. The results are applied to a new model of an economy with clubs. In contrast to the extant literature, our approach allows both widespread externalities and uniform results.

title: The Mind in Giambattista Vico's 'New Science'
Creators: name: Hepburn, Winthrop Brent
Publisher: name: The Open University
Year: 2011

description: This thesis is a reading and interpretation of Giambattista Vico's model of the human mind in the New Science. It focuses on the mind because understanding Vico's account of its origin and development is the key to assessing his overall claim of having discovered a new science of humanity. I contend that when the following three broad questions have been addressed the New Science will reveal a deeper and more complete dimension. The first is how Vico arrives at his thesis that the mind's development is a product of natural, social, and linguistic elements, rather than the emergence of innate faculties. Is this formulation coherent, and are there elements whose functions are not explained? The second is how he believed that a science of humanity was possible. Vico thought that true knowledge, or science, consisted in a synthesis of the esoteric and the practical. Was it realistic for him to suppose that these very different paradigms could coalesce and provide a backbone for scientific research? The third question is whether the accounts he gives of sacred and profane history are consistent and do not compromise his main thesis that history is human directed. Was Vico's explanation of the identity of the mind compatible with both narratives? It is intended that the development of the answers to these three questions will yield a new interpretation of the way Vico's account of the mind is understood.

The originality of this thesis lies in two main points. The first is that it proceeds with a description, in toto, of the phenomenon of mind that follows the unfolding of the phases of the ideal eternal history. Previous studies have treated the characteristics of mind in separate phases, but none to my knowledge takes the present approach of viewing the mind in its entirety as it persists throughout universal history. The second is that it explains that Vico's position throughout the New Science was that the persistence of mind is due to somatically-based activity. I point out that Vico was establishing a new paradigm for the mind in which meaning is created through connectedness to social and physical activity. This position is in stark contrast to computationist and rationalist theories of mind in which, theoretically, rational consciousness could exist apart from a physical platform. I have made use of many references to historical and contemporary sources about the mind and cognition in general. The purpose of these are, firstly, to provide an orientation to where Vico's ideas belong in the history of philosophy and, secondly, to indicate where those ideas may be situated or find resonance in contemporary theories of mind.

description: Topological metals (TMs) are a kind of special metallic materials, which feature nontrivial band crossings near the Fermi energy, giving rise to peculiar quasiparticle excitations. TMs can be classified based on the characteristics of these band crossings. For example, according to the dimensionality of the crossing, TMs can be classified into nodal-point, nodal-line, and nodal-surface metals. Another important property is the type of dispersion. According to degree of the tilt of the local dispersion around the crossing, we have type-I and type-II dispersions. This leads to significant distinctions in the physical properties of the materials, owing to their contrasting Fermi surface topologies. In this article, we briefly review the recent advances in this research direction, focusing on the concepts, the physical properties, and the material realizations of the type-II nodal-point and nodal-line TMs.

description: We prove an interior Schauder estimate for the Laplacian on metric products of two dimensional cones with a Euclidean factor, generalizing the work of Donaldson and reproving the Schauder estimate of Guo-Song. We characterize the space of homogeneous subquadratic harmonic functions on products of cones, and identify scales at which geodesic balls can be well approximated by balls centered at the apex of an appropriate model cone. We then locally approximate solutions by subquadratic harmonic functions at these scales to measure the Hölder continuity of second derivatives.

description: We introduce the concept of a parameterized collection of games with limited side payments, ruling out large transfers of utility. Under the assumption that the payo® set of the grand coalition is convex, we show that a game with limited side payments has a nonempty "-core. Our main result is that, when some degree of side-paymentness within nearly-e®ective small groups is assumed, then all payo®s in the "-core treat similar players similarly. A bound on the distance between "-core payo®s of any two similar players is given in terms of the parameters describing the game. These results add to the literature showing that games with many players and small e®ective groups have the properties of competitive markets.

Distinguishability theory for time-resolved photodetection and boson sampling

description: We study distinguishability of photons in multiphoton interference on a multiport when fast detectors, capable of precise time resolution, are employed. Such a setup was previously suggested for experimental realization of boson sampling with single photons. We investigate if fast photodetection allows to circumvent distinguishability of realistic single photons in mixed states. To this goal we compare distinguishability of photons in two setups: (a) with photons in the same average (temporal) profile on a spatial interferometer and photodetection incapable of (or with strongly imprecise) time resolution and (b) with photons in generally different average temporal profiles on the same spatial interferometer and photodetection with precise time resolution. Exact analytical results are obtained for Gaussian-shaped single photons with Gaussian distribution of photon arrival time. Distinguishability of photons in the two setups is found to be strikingly similar. For the same purity of photon states, only the same quality experimental boson sampling can be achieved using either of the two setups. The upshot of our results is that distinguishability due to mixed states is an intrinsic property of photons, whatever the photodetection scheme.
