description: The primary contribution of this thesis is to develop a series of hydroeconomic models to act as solution-oriented tools to conduct integrated groundwater management and provide fresh policy insights. Using spatially detailed economic and hydrologic data from a real-world aquifer, this thesis examines key groundwater management problems and suggests policies that might be used to control such systems. The thesis consists of three main essays focusing on issues in groundwater spatial dynamics and the design of optimal regulations. The first essay explores the importance of including well location decisions in spatially differentiated groundwater models to provide robust estimates of the gains from optimal management. Using a spatially differentiated and dynamic model of endogenous well location, this essay compares optimal and competitive extraction paths and well location decisions under alternative hypotheses as to the spatial distribution of groundwater. The second essay presents an integrated assessment of first and second-best management tools to regulate extraction from spatially heterogeneous aquifers. The trade-offs involved in each policy choice between welfare gains, redistribution effects, hydrological sustainability and implementation costs are examined. The essay also considers new approaches to groundwater management and analyses coordination between users via a generalisation of unitisation. Although decentralised profit-sharing systems have arisen organically for the exploitation of other spatially heterogeneous resources such as fisheries, no theoretical or empirical studies have formalised decentralised unitisation schemes in a modeling framework of groundwater extraction. The third essay investigates the use of multiple instruments for optimal groundwater management under the risk of occurrence of irreversible saltwater intrusion. This essay quantifies the trade-off between risk and efficiency involved in different instrument combinations implemented in an uncertain world. Using a numerical solution to a stochastic dynamic optimisation problem, the use of multiple policy instruments in aquifer management is justified in economic terms.

description: Including {\it world-sheet orientation-reversing automorphisms} $\hat{h}_σ \in H_-$ in the orbifold program, we construct the operator algebras and twisted KZ systems of the general WZW {\it orientation orbifold} $A_g (H_-) /H_-$. We find that the orientation-orbifold sectors corresponding to each $\hat{h}_σ \in H_-$ are {\it twisted open} WZW strings, whose properties are quite distinct from conventional open-string orientifold sectors. As simple illustrations, we also discuss the classical (high-level) limit of our construction and free-boson examples on abelian $g$.

Dynamics of the Globular Cluster System Associated with M49 (NGC4472): Cluster Orbital Properties and the Distribution of Dark Matter

description: We have measured radial velocities for 196 globular clusters (GCs) around M49, the brightest member of the Virgo Cluster. Combined with published data, they bring the total number of GCs with measured radial velocities in this galaxy to 263. Using this sample, we extract the projected kinematics of the full sample of GCs, and of the separate metal-poor and metal-rich subsamples. In agreement with previous results for the global GC kinematics based on smaller datasets, we find that the GC system as a whole exhibits a slow overall rotation that is due almost entirely to a net rotation of the metal-poor GC subsystem alone. In a spatial average, the metal-rich GCs shows essentially no rotation. We note, however, the presence of a well defined grouping of 10 metal-rich GCs that are located at opposite poles along the galaxy's major axis and which appear to be rotating at nearly 300 km/s about the minor axis. This grouping may be the relic of a past merger or accretion event. Using a Jeans-equation analysis, we show that the GC radial velocities alone point unequivocally (and independently of X-ray observations) to the need for a massive dark halo associated with M49 and the Virgo B subcluster around it. We also show that the GC system as a whole is consistent with an almost perfectly isotropic velocity ellipsoid. M49 is now the second elliptical galaxy (after M87) for which we have been able to demonstrate velocity isotropy in the globular cluster system overall, when no division based on GC color or metallicity is attempted. Thus, the data for these two galaxies lend support the general assumption of isotropy when using GC kinematics to study the dark-matter distribution in early-type galaxies. (ABRIDGED)

description: We report on the results of the longest uninterrupted observation of the Anomalous X-ray Pulsar 1RXS J1708-4009 obtained with the BeppoSAX satellite in August 2001. In the phase-resolved spectrum, corresponding to the rising part of the pulse, we found an absorption-like feature at 8.1 keV (significance level of 4 sigma), most likely due to cyclotron resonant scattering. The centroid energy converts to a magnetic field of 9x10^{11} G and 1.6x10^{15} G in the case of electrons and protons, respectively. If confirmed, this would be the first detection of a cyclotron feature in the spectrum of an anomalous X-ray pulsar. We discuss here the results also in ligh of recent theoretical models for these class of sources.

 Material examined. NW Madagascar, BENTHEDI, Stn CH 90, 3700 m: 1 M 20.9 mm (MNHN-Ga1576).
 Remarks. The specimen examined agrees with the specimens from the Atlantic Ocean (Macpherson & Segonzac 2005). However, the specimen from Madagascar has no epipods in P1, which are present in the Atlantic Ocean material. Additional specimens from the Indian Ocean may clarify the taxonomic value of this difference.
 Distribution. Atlantic Ocean, from North Carolina (type locality) to the Bay of Biscay, Azores, Canary Islands, Middle Atlantic Bight, Caribbean Sea and off Namibia, between 2679 and 5315 m (Smith 1885, A. Milne-Edwards & Bouvier 1899, Bouvier 1922, Gordon 1955, Sivertsen & Holthuis 1956, Pequegnat & Pequegnat 1971, T¸rkay 1975, Wenner 1982, Macpherson & Segonzac 2005). Recently the species has been cited in the Tasman Sea, at 3580 m (Baba 2005). The present material is the first record in the Indian Ocean.

description: Recently, the advent of deep learning has spurred interest in the development of physics-informed neural networks (PINN) for efficiently solving partial differential equations (PDEs), particularly in a parametric setting. Among all different classes of deep neural networks, the convolutional neural network (CNN) has attracted increasing attention in the scientific machine learning community, since the parameter-sharing feature in CNN enables efficient learning for problems with large-scale spatiotemporal fields. However, one of the biggest challenges is that CNN only can handle regular geometries with image-like format (i.e., rectangular domains with uniform grids). In this paper, we propose a novel physics-constrained CNN learning architecture, aiming to learn solutions of parametric PDEs on irregular domains without any labeled data. In order to leverage powerful classic CNN backbones, elliptic coordinate mapping is introduced to enable coordinate transforms between the irregular physical domain and regular reference domain. The proposed method has been assessed by solving a number of PDEs on irregular domains, including heat equations and steady Navier-Stokes equations with parameterized boundary conditions and varying geometries. Moreover, the proposed method has also been compared against the state-of-the-art PINN with fully-connected neural network (FC-NN) formulation. The numerical results demonstrate the effectiveness of the proposed approach and exhibit notable superiority over the FC-NN based PINN in terms of efficiency and accuracy.

description: The February 6th Kahramanmaraş Earthquakes devastated Turkey and Syria, claiming 51,000 lives and destroying 160,000 buildings. With 300-kilometer fracture lines, 7.8 Mw. and 7.5 Mw. quakes left 180,000 in container homes. Hatay, a southern Turkish city, faced significant damage, with 80% of remaining buildings set for demolition. Months later, people still live in tents and public parks, facing uncertainty. This study explores earthquake-resilient landscape design, focusing on the relationship between public space, drinking water, food, and housing crises, addressing how the landscape can become a refuge in Hatay. The graduate project delves into the recovery process, meeting earthquake victims’ needs, and restoring the relationship with the Asi River.

description: In the fast growing two-dimensional (2D) materials family, anisotropic 2D materials, with their intrinsic in-plane anisotropy, exhibit a great potential in optoelectronics. One such typical material is black phosphorus (BP), with a layer-dependent and highly tunable band gap. Such intrinsic anisotropy adds a new degree of freedom to the excitation, detection and control of light. Particularly, hyperbolic plasmons with hyperbolic q-space dispersion are predicted to exist in BP films, where highly directional propagating polaritons with divergent densities of states are hosted. Combined with a tunable electronic structure, such natural hyperbolic surfaces may enable a series of exotic applications in nanophotonics. In this review, the anisotropic optical properties and plasmons (especially hyperbolic plasmons) of BP are discussed. In addition, other possible 2D material candidates (especially anisotropic layered semimetals) for hyperbolic plasmons are examined. This review may stimulate further research interest in anisotropic 2D materials and fully unleash their potential in flatland photonics.

description: For the first time the neutron-rich hydrogen isotope $\rm ^{6}H$ was produced in an electron scattering experiment in the reaction $\rm ^{7}Li(e,~e'pπ^{+})^{6}H$ using the spectrometer facility of the A1 Collaboration at the Mainz Microtron accelerator. By measuring the triple coincidence between the scattered electron, the produced proton, and $π^{+}$, the missing mass spectrum of $\rm ^{6}H$ was obtained. A clear peak above $^3$H+n+n+n energy threshold was seen resulting in a ground state energy of $\rm ^{6}H$ at $2.3\pm0.5({\rm stat.})\pm0.4({\rm syst.})$ MeV with a width of $1.9\pm1.0({\rm stat.})\pm0.4({\rm syst.})$ MeV. This work challenges the understandings of multi-nucleon interactions and presents a new method to study light neutron-rich nuclei with electron scattering experiments.

description: In this paper, we review several important features of the out-of-equilibrium dynamics of spin glasses. Starting with the simplest experiments, we discuss the scaling laws used to describe the isothermal aging observed in spin glasses after a quench down to the low temperature phase. We report in particular new results on the sub-aging behaviour of spin glasses. We then discuss the rejuvenation and memory effects observed when a spin glass is submitted to temperature variations during aging, from the point of view of both energy landscape pictures and of real space pictures. We highlight the fact that both approaches point out the necessity of hierarchical processes involved in aging. Finally, we report an investigation of the effect of small temperature variations on aging in spin glass samples with various anisotropies which indicates that this hierarchy depends on the spin anisotropy.

description: A perturbative calculation of the correlator of three parallel open Wilson lines is performed for the U(N) theory in two non-commutative space-time dimensions. In the large-N planar limit, the perturbative series is fully resummed and asymptotically leads to an exponential increase of the correlator with the lengths of the lines, in spite of an interference effect between lines with the same orientation. This result generalizes a similar increase occurring in the two-line correlator and is likely to persist when more lines are considered provided they share the same direction.

description: MASCARA-4 b is a hot Jupiter in a highly-misaligned orbit around a rapidly-rotating A3V star that was observed for 54 days by the Transiting Exoplanet Survey Satellite (\tess). We perform two analyses of MASCARA-4 b using a stellar gravity-darkened model. First, we measure MASCARA-4 b's misaligned orbital configuration by modeling its \tess~photometric light curve. We take advantage of the asymmetry in MASCARA-4 b's transit due to its host star's gravity-darkened surface to measure MASCARA-4 b's true spin-orbit angle to be $104^{\circ+7^\circ}_{-13^\circ}$. We also detect a $\sim4σ$ secondary eclipse at $0.491\pm0.007$ orbital phase, proving that the orbit is slightly eccentric. Second, we model MASCARA-4 b's insolation including gravity-darkening and find that the planet's received XUV flux varies by $4$\% throughout its orbit. MASCARA-4 b's short-period, polar orbit suggests that the planet likely underwent dramatic orbital evolution to end up in its present-day configuration and that it receives a varying stellar irradiance that perpetually forces the planet out of thermal equilibrium. These findings make MASCARA-4 b an excellent target for follow-up characterization to better understand orbital evolution and current-day of planets around high-mass stars.

description: We investigate the interplay of two highly localized, nearly degenerate electronic states, namely, a zero-energy edge mode in a graphene nanoribbon on the one hand and an Abrikosov-Suhl resonance located at a Kondo impurity on the other. On-surface synthesis of the ribbon structures in combination with intercalation of single atom Kondo impurities by atomic manipulation in a scanning tunneling microscope junction offer full control of the atomic geometry of the system. Density functional theory provides the microscopic description to scrutinize the electronic features observed in experiment. We find the interaction of the two localized states and the resulting signatures of Kondo physics to be very sensitive to the placing of the atom, suggesting its use as a laboratory to study the interplay of the Kondo effect with other zero-bias anomalies as well as to tailor these states by controlling the atomic-scale coupling.

An ordinary relativistic gas can serve as the matter source for the 2-2-hole solution of quadratic gravity, and this leads to a calculable area-law entropy. Here we show that it also leads to an estimate of the damping of a gravitational wave as it travels to the center of the 2-2-hole and back out again. We identify two frequency dependent effects that greatly diminish the damping. Spinning 2-2-hole solutions are not known, but we are still able to consider some spin dependent effects. The frequency and spin dependence of the damping helps to determine the possible echo resonance signal from the rotating remnants of merger events. It also controls the fate of the ergoregion instability.

description: In a celebrated paper, Dyson shows that the spectrum of an n\times n random Hermitian matrix, diffusing according to an Ornstein-Uhlenbeck process, evolves as n noncolliding Brownian motions held together by a drift term. The universal edge and bulk scalings for Hermitian random matrices, applied to the Dyson process, lead to the Airy and Sine processes. In particular, the Airy process is a continuous stationary process, describing the motion of the outermost particle of the Dyson Brownian motion, when the number of particles gets large, with space and time appropriately rescaled. In this paper, we answer a question posed by Kurt Johansson, to find a PDE for the joint distribution of the Airy process at two different times. Similarly we find a PDE satisfied by the joint distribution of the Sine process. This hinges on finding a PDE for the joint distribution of the Dyson process, which itself is based on the joint probability of the eigenvalues for coupled Gaussian Hermitian matrices. The PDE for the Dyson process is then subjected to an asymptotic analysis, consistent with the edge and bulk rescalings. The PDEs enable one to compute the asymptotic behavior of the joint distribution and the correlation for these processes at different times t_1 and t_2, when t_2-t_1\to \infty, as illustrated in this paper for the Airy process. This paper also contains a rigorous proof that the extended Hermite kernel, governing the joint probabilities for the Dyson process, converges to the extended Airy and Sine kernels after the appropriate rescalings.

Potrebbero esserci due stelle esotiche – erroneamente scambiate per buchi neri – all’origine di Gw 190521, un evento di onde gravitazionali annunciato nel settembre 2020 da Ligo e Virgo. Uno scenario che risolverebbe il problema della massa proibitiva (nel caso fossero buchi neri) di uno degli oggetti in collisione, e costituirebbe la prima prova dell’esistenza di bosoni ultraleggeri proposti anche come costituenti della materia oscura

description: We present a formulation of the initial state of heavy ion collisions that generalizes the 2+1D boost invariant IP-Glasma \cite{Schenke:2012wb} to 3+1D through JIMWLK rapidity evolution of the pre-collision Wilson lines. The rapidity dependence introduced by the JIMWLK evolution leads us to modify the initial condition for the gauge fields, and to solve Gauss' law iteratively in order to allow for temporal evolution on a 3-dimensional lattice. While the transverse physics of QGP has been studied nearly exhaustively, the effect of longitudinal fluctuations introduced by the JIMWLK evolution has yet to be studied in detail phenomenologically. Hence, we couple our 3+1D IP-Glasma model to MUSIC+UrQMD, for completely 3+1D simulations of heavy ion collisions. Specifically, we consider Pb-Pb collisions at $\sqrt{s} = 2.76\, {\rm TeV}$ and study the rapidity dependence of the charged hadron $v_n(η)$ via the $η$-dependent flow factorization ratios $r_n(η_a,η_b)$ as measured by CMS \cite{Khachatryan:2015oea}, as well as the charged hadron multiplicity $dN_{ch}/dη$.

description: Progress in electron-beam spectroscopies has recently enabled the study of optical excitations with combined space, energy and time resolution in the nanometer, millielectronvolt and femtosecond domain, thus providing unique access into nanophotonic structures and their detailed optical responses. These techniques rely on $\approx$ 1-300 keV electron beams focused at the sample down to sub-nanometer spots, temporally compressed in wavepackets a few femtoseconds long, and in some cases controlled by ultrafast light pulses. The electrons undergo energy losses and gains, also giving rise to cathodoluminescence light emission, which are recorded to reveal the optical landscape along the beam path. This review portraits these advances, with a focus on coherent excitations, emphasizing the increasing level of control over the electron wave functions and ensuing applications in the study and technological use of optically resonant modes and polaritons in nanoparticles, 2D materials and engineered nanostructures.

On the electrical conductivity of metals with a rough surface

description: We discuss surface roughness effects on the conduction of electrons in metals using both the quantal Kubo-Greenwood formalism and the semi-classical Fuchs-Sondheimer method. The main purpose here is to compare these methods and clarify a few subtle conceptual issues. One of such issues is concerned with the conditions under which the broken translation symmetry along a rough surface may be restored. This symmetry has often been presumed in existing work but not always with proper justifications. Another one relates to the physical meaning of a phenomenological parameter (denoted by $p$) intuitively introduced in the semi-classical theory. This parameter, called the specularity parameter or sometimes the \textit{Fuchs} parameter, plays an important role in the experimental studies of surface roughness but has so far lacked a rigorous microscopic definition. The third issue arises as to the domain of validity for the electrical conductivity obtained in those methods. A misplacement of the domain may have resulted in erroneous analysis of surface effects in a variety of electrodynamic phenomena including surface plasma waves.

description: The dwarf galaxies comparable to the LMC and SMC, with stellar masses $7.5 <{\rm log}(M_{\ast}/M_{\odot})<9.5$, are found in a diversity of environments and have long quenching timescales. We need to understand how this phenomenon is connected to the dwarfs' halo properties and their locations in the large-scale structure of the universe. We study the star-formation rates of dwarfs in the TNG50 simulation of the IllustrisTNG project across different environments, focusing on field dwarfs in host halos with virial masses of $9 < {\rm log}(M_{200}/M_{\odot}) < 11.5$, in contrast to dwarf satellites in hosts with ${\rm log}(M_{200}/M_{\odot}) \geq 11.5$. Our field dwarf sample is heterogeneous, consisting of primary (central) galaxies, with smaller numbers of secondaries and dwarf galaxies that are on backsplash orbits around massive galaxies. We study how the quenched fraction and star-formation histories depend on the dwarfs' large-scale environment and find that only $\sim 1\%$ of the most isolated dwarfs are quenched. The vast majority of the quenched field dwarfs are backsplash dwarfs located in the neighborhood of cluster-scale halos. We discover a two-halo galactic conformity signal that arises from the tendency of the quenched dwarfs, particularly the backsplash sample, to have a quenched massive galaxy as a neighbor. We attribute the low quenched fractions of the simulated LMC/SMC analogs in the field to the locations of their low-mass hosts in the sparse large-scale environment, which predominate over the relatively small number of backsplash and quenched primary dwarfs in denser environments.

description: The pressure dependence of light-induced effects in single-crystalline BiFeO$_3$ is studied by optical spectroscopy. At low pressures, we observe three light-induced absorption features with energies just below the two crystal field excitations and the absorption onset, respectively. These absorption features were previously ascribed to excitons, possibly connected with the ultra-fast photostriction effect in BiFeO$_3$. The pressure-induced redshift of the absorption features follows the pressure dependence of the corresponding crystal field excitations and absorption onset, suggesting the link between them. Above the structural phase transition at $P_{\mathrm{c1}}\approx{}3.5$ GPa the three absorption features disappear, suggesting their connection to the polar phase in BiFeO$_3$. The pressure-induced disappearance of the photo-induced features is irreversible upon pressure release.

Eppur è piatto? Così l’universo torna euclideo

Per misurare la curvatura dell’universo, bisogna trovare il righello giusto. È quanto sono riusciti a fare tre cosmologi usando i “cronometri cosmici”: un insieme di galassie massicce e passive lontane fino a dieci miliardi di anni luce. Grazie al ticchettio dell’espansione dell’universo scandito da questi cronometri, è possibile misurare la curvatura: nonostante i precedenti risultati del satellite Planck, risulterebbe piatto.
