description: Governance by disclosure has been the longstanding expectation for global environmental governance bodies but increases in federal regulations have caused changes to perceptions and practices of transparency. Using interviews with executive directors for the UN Global Compact and its national secretariats, the dissertation introduces a relational approach to transparency by highlighting three prominent relationship types in the network of the United Nations Global Compact. The first relationship between the UNGC to corporations can be perceived in terms of partnerism, and transparency here is practiced as embedded disclosure. The second relationship is between governments and corporations and can be perceived as co-optive; here, transparency is practiced as mandatory disclosure. The third relationship is between corporate actors, where the relationship is perceived as co-opetitive, and transparency is practiced as selective disclosure. The implications of this relational perspective of transparency include (1) transparency is understood as multidimensional, (2) transparency recursively shapes the network, and (3) transparency distorts power asymmetries. Although there is a longstanding tradition of environmental reporting among corporate actors, there are reasons to assume that environmental reporting has changed in an era of visibility. This dissertation then uses an extended case study of IKEA environmental reporting and sustainability communication practices to advance the notion of a constant report, a kind of sustained sustainability campaign where information is constant, relentless, and highly visible. I derive six characteristics of the constant report, including (1) the constant report is visible; (2) the constant report is networked; (3) the constant report is pluralistic; (4) the constant report is personalized; (5) the constant report is promotional; (6) the constant report is performative. This has important implications for digital ubiquity on environmental reporting, exploring a concept called authentic babble to denote the simultaneous authenticity and performativity that occurs within environmental reporting today.

description: Neutrons produced by cosmic muon interactions are important contributors to backgrounds in underground detectors when searching for rare events. Typically such neutrons can dominate the background, as they are particularly difficult to shield and detect. Since actual data is sparse and not well documented, simulation studies must be used to design shields and predict background rates. Thus validation of any simulation code is necessary to assure reliable results. This work compares in detail the predictions of the FLUKA simulation code to existing data, and uses this code to report a simulation of cosmogenic backgrounds for typical detectors embedded in a water tank with liquid scintillator shielding.

description: Turbulent gas motion inside galaxy clusters provides a non-negligible non-thermal pressure support to the intracluster gas. If not corrected, it leads to a systematic bias in the estimation of cluster masses from X-ray and Sunyaev-Zel'dovich (SZ) observations assuming hydrostatic equilibrium, and affects interpretation of measurements of the SZ power spectrum and observations of cluster outskirts from ongoing and upcoming large cluster surveys. Recently, Shi & Komatsu developed an analytical model for predicting the radius, mass, and redshift dependence of the non-thermal pressure contributed by the kinetic random motions of intracluster gas sourced by the cluster mass growth. In this paper, we compare the predictions of this analytical model to a state-of-the-art cosmological hydrodynamics simulation. As different mass growth histories result in different non-thermal pressure, we perform the comparison on 65 simulated galaxy clusters on a cluster-by-cluster basis. We find an excellent agreement between the modelled and simulated non-thermal pressure profiles. Our results open up the possibility of using the analytical model to correct the systematic bias in the mass estimation of galaxy clusters. We also discuss tests of the physical picture underlying the evolution of intracluster non-thermal gas motions, as well as a way to further improve the analytical modeling, which may help achieve a unified understanding of non-thermal phenomena in galaxy clusters.

Internal structure of exotic hadrons by high-energy exclusive reactions

subject: FOS: Physical sciences

description: We propose to use high-energy exclusive reactions for probing internal structure of exotic hadron candidates. First, the constituent counting rule of perturbative QCD can be used for finding internal configurations of an exotic hadron candidate. It is because the number of constituents ($n$), which participate in the exclusive reaction, is found by the scaling behavior of the cross section $dσ/dt \propto 1/s^{n-2}$ at large momentum transfer, where $s$ is the center-of-mass energy squared. As an example, we show that the internal structure of $Λ\, (1405)$ should be found, for example, by the reaction $π^- + p \to K^0 + Λ(1405)$. Second, the internal structure of exotic hadron candidates should be investigated by hadron tomography with generalized parton distributions (GPDs) and generalized distribution amplitudes (GDAs) in exclusive reactions. Exotic nature should be reflected in the GPDs which contain two factors, longitudinal parton distributions as indicated by the constituent counting rule and transverse form factors as suggested by the hadron size. The GDAs should be investigated by the two-photon process $γ^* γ\to h\bar h$, for example $h=f_0$ or $a_0$, in electron-positron annihilation. Since the GDAs contain information on a time-like form factor, exotic nature should be found by studying the $h\bar h$ invariant mass dependence of the cross section. The internal structure of exotic hadron candidates should be clarified by the exclusive reactions at facilities such as J-PARC and KEKB.

On the exact formulation of multi-configuration density-functional theory: electron density versus orbitals occupation

Subjects: subject: Chemical Physics (physics.chem-ph)
subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The exact formulation of multi-configuration density-functional theory (DFT) is discussed in this work. As an alternative to range-separated methods, where electron correlation effects are split in the coordinate space, the combination of Configuration Interaction methods with orbital occupation functionals is explored at the formal level through the separation of correlation effects in the orbital space. When applied to model Hamiltonians, this approach leads to an exact Site-Occupation Embedding Theory (SOET). An adiabatic connection expression is derived for the complementary bath functional and a comparison with Density Matrix Embedding Theory (DMET) is made. Illustrative results are given for the simple two-site Hubbard model. SOET is then applied to a quantum chemical Hamiltonian, thus leading to an exact Complete Active Space Site-Occupation Functional Theory (CASSOFT) where active electrons are correlated explicitly within the CAS and the remaining contributions to the correlation energy are described with an orbital occupation functional. The computational implementation of SOET and CASSOFT as well as the development of approximate functionals are left for future work.

description: We show the derivation of the self-duality relation of abelian higher-form gauge field strength in the topologically nontrivial spacetime background. The so-called Pasti-Sorokin-Tonin action for the self-dual abelian gauge field assumes that the spacetime topology is trivial to derive the self-duality relation using a gauge transformation of the action. In this paper we find a new gauge transformation of the same theory and show that this new gauge transformation enables us to derive the self-duality relation even in the topologically nontrivial spacetime background.

description: Spatial modeling of wireless networks via analytical means has been considered as a widely practiced mechanism for inference. As a result, some geometrical deployment models have been proposed in literature. Although practical in certain simulation instances, these models do not always produce inhomogeneous nodal geometries in an effective and simple manner for practical deployment situations. Therefore, we conceptualized a flexible approach for realizing random inhomogeneity by proposing the area-specific deployment (ASD) algorithm, which takes into account the clustering tendency of users. Overall, the developed spatial-level network tool has the distinct advantage of automatically producing infinitely many random realizations of users' geometry by simply entering three parameters to the simulator: the size of the cellular network, the number of deployment layers, and the overall quantity of nodes.

description: Seismic engineering, a vital field at the intersection of science, engineering, and disaster mitigation, relies on Ground Motion Prediction Equations (GMPEs) to assess earthquake risk and design resilient structures. This article delves into the intricate science behind GMPEs, shedding light on their core principles. GMPEs draw from historical seismic data, geological insights, and mathematical modeling to predict ground motions during earthquakes. They are the result of interdisciplinary collaboration and continue to evolve with advances in data collection and computational capabilities. GMPEs find diverse applications, from seismic hazard analysis to earthquake early warning systems, guiding land-use planning and retrofitting decisions. They play a pivotal role in reducing uncertainties in ground motion predictions and have region-specific models tailored to geological variations. Open-source GMPE models promote knowledge sharing, contributing to global efforts to enhance seismic resilience. This article empowers professionals and enthusiasts with a deeper appreciation of GMPEs' role in safeguarding structures, communities, and lives in the face of seismic threats.

description: Future arcminute resolution polarization data from ground-based Cosmic Microwave Background (CMB) observations can be used to estimate the contribution to the temperature power spectrum from the primary anisotropies and to uncover the signature of reionization near $\ell=1500$ in the small angular-scale temperature measurements. Our projections are based on combining expected small-scale E-mode polarization measurements from Advanced ACTPol in the range $3001500$, leading to a measurement of the amplitude of matter density fluctuations, $σ_8$, at $1\%$ precision. Alternatively, by exploring the reionization signal encoded in the patchy kSZ measurements, we bound the time and duration of the reionization with $σ(z_{\rm re})=1.1$ and $σ(Δz_{\rm re})=0.2$. We find that these constraints degrade rapidly with large beam sizes, which highlights the importance of arcminute-scale resolution for future CMB surveys.

Optimisation of numerically modelling rotating wheels in CFD
Creators: name: Heath, Nicholas
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Vehicle wheels can contribute up to 30% of total vehicle aerodynamic drag which directly increases fuel consumption and emissions, highlighting the importance of accurate aerodynamic modelling. Flow structures created by detailed rotating wheels remain difficult to predict and analyse due to geometrical complexities and limitations of experimental studies, with previous numerical investigations often simplifying the geometries of vehicle wheels. A comprehensive numerical investigation was conducted using various techniques to model wheel rotation on the DrivAer model with standard wheels and detailed wheels. It was found that modelling rotation produced lift and drag reductions of up to 150% and 6.9% respectively with the standard wheel compared to the static wheel case, and reductions of up to 272% and 9.3% respectively for the detailed wheel. Key differences in flow structures were observed between static and rotating cases and also between the various rotation modelling techniques, with characteristic vortices and flow separation varying in position and magnitude greatly. The difference in lift and drag prediction between different rotation modelling techniques varies as much as ΔCL = 0.056 and ΔCD = 0.022 respectively for the detailed wheel. Unsteady simulations also revealed transient features which were not captured by the steady-state models.

description: Aims. The co-evolution of galaxies and super massive black holes (SMBHs) requires that some sort of feedback mechanism is operating during the active galactic nuclei (AGN) phases. AGN driven winds are the most likely candidates for such feedback mechanism, but direct observational evidence of their existence and of their effects on the host galaxies are still scarce and their physical origin is still hotly debated. Methods. X-shooter observations of a sample of X-ray selected, obscured quasars at z$\sim$1.5, selected on the basis of their observed red colors and X-ray-to-optical flux ratio, have shown the presence of outflowing ionized gas identified by broad [OIII] emission lines in 6 out of 8 objects, confirming the efficiency of the selection criteria. Here we present slit-resolved spectroscopy for the two brightest sources, XID2028 and XID5321, to study the complex emission and absorption line kinematics. Results. We detect outflow extended out to $\sim$ 10 kpc from the central black hole (BH), both as blueshifted and redshifted emission. Interestingly, we also detect kpc scale outflows in the [OII] emission lines and in the neutral gas component, traced by the sodium D and magnesium absorption lines, confirming that a substantial amount of the outflowing mass is in the form of neutral gas. Conclusions. The measured gas velocities and the outflow kinetic powers, inferred under reasonable assumptions on the geometry and physical properties of these two systems, favor an AGN origin for the observed winds.

description: The presence of the anomalous top quark flavour changing neutral current (FCNC) interactions leads to the production of same-sign top quarks in proton-proton collisions. The results of a search for events with same-sign dileptons and b-jets conducted by CMS collaboration with 10.5 $fb^{-1}$ of data collected in pp colisions at $\sqrt{s}=8$ TeV are used to obtain the constraints on the strength of top quark FCNC interactions. The 95$%$ confidence level upper limits on the branching ratios of top quark decays to a light quark $q=u,c$ and a gauge or a Higgs boson are set to be ${\cal B}R(t\rightarrow u γ) < 1.27%$, ${\cal B}R(t\rightarrow u Z) < 0.8% $, ${\cal B}R(t\rightarrow u g) < 1.02% $ and ${\cal B}R(t\rightarrow u H) < 4.21% $. The sensitivity of future searches in the same-sign top quark channel is also presented.

description: The Epoch of Reionization (EoR) represents a milestone in the evolution of our Universe. Star-forming galaxies that existed during the EoR likely emitted a significant fraction (~5-40%) of their bolometric luminosity as Lyman Alpha (Lya) line emission. However, neutral intergalactic gas that existed during the EoR was opaque to Lya emission that escaped from galaxies during this epoch, which makes it difficult to observe. The neutral intergalactic medium (IGM) may thus reveal itself by suppressing the Lya flux from background galaxies. Interestingly, a `sudden' reduction in the observed Lya flux has now been observed in galaxies at z >6. This review contains a detailed summary of Lya radiative processes: I describe (i) the main Lya emission processes, including collisional-excitation & recombination (and derive the famous factor `0.68'), and (ii) basic radiative transfer concepts, including e.g. partially coherent scattering, frequency diffusion, resonant versus wing scattering, optically thick versus 'extremely' optically thick (static/outflowing/collapsing) media, and multiphase media. Following this review, I derive expressions for the Gunn-Peterson optical depth of the IGM during (inhomogeneous) reionization and post-reionization. I then describe why current observations appear to require a very rapid evolution of volume-averaged neutral fraction of hydrogen in the context of realistic inhomogeneous reionization models, and discuss uncertainties in this interpretation. Finally, I describe how existing & futures surveys and instruments can help reduce these uncertainties, and allow us to fully exploit Lya emitting galaxies as a probe of the EoR.

Wasteland rehabilitation in rural landscape: a design project in the Verona plain

Year: 2018

description: This contribution presents a design exploration for the rehabilitation of a dumpsite in the mu-nicipality of Isola Rizza, Verona (Italy). In the Verona plain, a former district of brick production left in its wake a cluster of water basins and wastelands that are today distinctive of the land-scape and object of a territorial dispute among landowners, public administrations, and the lo-cal community. A project for the rehabilitation of one of those wastelands, converted into a dumpsite, has been recently developed. It considers the idea of re-organizing the circulation of waste materials and soil involved in the remediation to implement a public park. Although the project has been facing the little consideration given by local regulations to integrated design, it clearly shows the capacity of systemic design to tackle rehabilitation challengering potential spaces integrated with the local ecological and slow mobility networks.

description: A general theoretical framework for investigating nonlinear dynamics of phase space zonal structures is presented in this work. It is then, more specifically, applied to the limit where the nonlinear evolution time scale is smaller or comparable to the wave-particle trapping period. In this limit, both theoretical and numerical simulation studies show that non-adiabatic frequency chirping and phase locking could lead to secular resonant particle transport on meso- or macro-scales. The interplay between mode structures and resonant particles then provides the crucial ingredient to properly understand and analyze the nonlinear dynamics of Alfvén wave instabilities excited by non-perturbative energetic particles in burning fusion plasmas. Analogies with autoresonance in nonlinear dynamics and with superradiance in free electron lasers are also briefly discussed.
Rethinking the Spaces of Waste Management Infrastructure: towards integrated urban strategies to avoid urban solid waste in contemporary city
Creators: name: Massaro, Saverio
Publisher: name: Ri-Vista
Year: 2018

description: This paper examines the issue of solid waste management in urban contexts, by an architectural perspective. In light of the emerging waste crisis, this paper proposes to redesign and gradually reintroduce waste management facilities in the urban tissue. The capacity to learn from trash can help to design a new generation of facilities, aiming to recover suburban areas and to re-establish a lost ecological balance. The paper underlines the need to radically reconsider the spatial articulation and the organizational structure of the current waste management infrastructure, through an integrateed approach aiming to define a decentralized and distributed urban model. Finally the paper explores heuristic potentials for architectural design, identifying hybrid figures and finding key actions to intervene in the contemporary city, inspired by the notion of ‘unblackboxing’.

Ground state octupole correlation energies with effective forces

description: The ground state octupole correlation energy is computed with the D1M variant of the Gogny force in different theoretical frameworks and analyzed in detail. First I consider the correlation energy gained at the mean field level by breaking reflection symmetry. Next I consider the energy gain coming from symmetry (parity) restoration and finally I analyze the ground state correlation energy after configuration mixing with axially symmetric octupole states. The impact of the latter on theoretical binding energies indicates that octupole correlations do not affect in a significant way the trend and systematic of binding energies and therefore can not improve the performance of theoretical models in this respect. In particular, the too-large "shell gaps" predicted by self-consistent mean field models and relevant in astrophysics scenarios are not altered by the octupole correlations.

description: Wigner's famous 1939 classification of positive energy representations, combined with the more recent modular localization principle, has led to a significant conceptual and computational extension of renormalized perturbation theory to interactions involving fields of higher spin. Traditionally the clash between pointlike localization and the the Hilbert space was resolved by passing to a Krein space setting which resulted in the well-known BRST gauge formulation. Recently it turned out that maintaining a Hilbert space formulation for interacting higher spin fields requires a weakening of localization from point- to string-like fields for which the d=s+1 short distance scaling dimension for integer spins is reduced to d=1 and and renormalizable couplings in the sense of power-counting exist for any spin. This new setting leads to a significant conceptual change of the relation of massless couplings with their massless counterpart. Whereas e.g. the renormalizable interactions of s=1 massive vectormesons with s<1 matter falls within the standard field-particle setting, their zero mass limits lead to much less understood phenomena as "infraparticles" and gluon/quark confinement. It is not surprising that such drastic conceptual changes in the area of gauge theories also lead to a radical change concerning the Higgs issue.

description: We explore the arguments presented in the past linking changes in the angular momentum $modulus$, $|{\bf L}|$, of the Sun's barycentric orbit, with the discharges of Po River in Europe and Paraná River in South America, looking for any evidence regarding to a possible underlying physical mechanism. We clarify the planetary effect on solar torque presenting new analyses and results; we also improve prior results on Paraná River's cycles finding significant spectral lines around 6.5 yr, 7.6 yr, 8.7 yr, and 10.4 yr. We show that the truly important dynamical parameter in this issue is the {\it vectorial} planetary torque. Moreover, following the variations of ${\bf L}$ respect to the Sun's spin axis of rotation (i.e., a LS relationship), we found virtually the same Paraná River discharge peaks: 6.3 yr, 7.7 yr, 8.6 yr and 9.9 yr. An analisys based on Magnitude Squared Coherence and Wavelet Coherence between Paraná River discharge and our LS relationship shows significant, although intermittently, coherence near 8-yr periodicities. Wavelet Coherence also shows big and significant regions of coherence inside 12-19 yr band. Our results ruled out classical tidal effects in this problem; but suggest that, if these rivers are trully related to solar barycentric motion, the physical origin of this connection might be related to a working solar spin-orbit interaction.

description: Recently IceCube collaboration has reported first evidence for the astrophysical neutrinos. Observation corresponds to the total astrophysical neutrino flux of the order of $3 \cdot 10^{-8}$ $GeV/cm^2/s/sr$ in a PeV energy range. Active Galactic Nuclei (AGN) are natural candidate sources for such neutrinos. To model the neutrino creation in AGNs we study photopion production processes on the radiation field of the Shakura-Sunyaev accretion disks in the black hole vicinity. We show that this model can explain detected neutrino flux and avoids, at the same time, existing constraints from the gamma-ray and cosmic ray observations.

Afteruse of Landfills. Methodological approach, project requisites and relationship with the surrounding area
Creators: name: Artuso, Anna

Publisher: name: Ri-Vista
Year: 2018

description: Sanitary landfills still today represent one of the most widely applied methods of waste management. However, the characteristics of this type of plant represent a particular challenge for the environment due to the potential release of pollutants, for the surrounding area as the plant may affect local organization and functions, and for the landscape as both the size and the morphology of a landfill may establish new relationships with the landscape. In the case of older landfills, reclamation measures are frequently required, although these can be undertaken to enable co-existence with modern waste disposal operations based on an integrated system of waste management, and should be included by land-use urban planning as a place of mutual interest to the community. The modern landfills designed to reduce the impact produced on the environment and the territory, may provide an opportunity to intervene with large scale projects. Based on these premises, it would be interesting to focus on the possibility of future reclamation of the landfills under construction during the design stage by applying an approach that takes into account future use from a technical and, economical perspective from the outset.

Tilted loop currents in cuprate superconductors
Creators: name: Yakovenko, Victor M.
Publisher: name: arXiv
Year: 2014
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The paper briefly surveys theoretical models for the polar Kerr effect (PKE) and time-reversal symmetry breaking in the pseudogap phase of cuprate superconductors. By elimination, the most promising candidate is the tilted loop-current model, obtained from the Simon-Varma model by tilting one triangular loop up and another one down toward the apical oxygens. The model is consistent with the PKE, spin-polarized neutron scattering, and optical anisotropy measurements. Spontaneous currents in this model flow between the in-plane and apical oxygens in such a manner that each oxygen belongs to one current loop. This loop-current pattern is similar to the spin order in the magnetoelectric antiferromagnet Cr2O3, where the PKE is observed experimentally. By analogy, it should be possible to train the PKE sign in the cuprates magnetoelectrically. Several experiments are proposed to confirm the loop-current order: the magnetic-field-induced polarity, the nonlinear anomalous Hall effect, and the second-harmonic generation.

A recovered landfill in the construction of a metropolis: The Valdemingómez project, over time
Creators: name: Alba, Israel
Publisher: name: Ri-Vista
Year: 2018

description: The project for the recovery and transformation of the Valdemingómez landfill in Madrid required the application of complex environmental engineering processes, as well as new architectural strategies. Today, it is a place which can be incorporated, with full guarantees, into the city structure, as long as it is viewed as a monumental public space. It is recovered ground which is capable of becoming a new, free metropolitan space that can respond to the current and future needs of society, especially if it remains as such over time. The architectural project which was undertaken involved the proposal of new strategies for creating an area which will be open, flexible and dynamic throughout time, in a search for equilibrium between city and nature. The Valdemingómez landfill constitutes an example of a proposed model of continuity between the forest and the surrounding area; a pseudo botanical garden with indigenous species seeking integration into the Parque Regional del Sureste(Southeast Regional Park). It was transformed into a free, public area with pedestrian paths and bicycle lanes, along with woods and wetlands which have helped to create small, localized ecosystems. Within it, one can observe the life of both nature and the city.

The Architecture of Waste. Designing new avenues for public engagement with trash
Creators: name: Muller, Jeannine
Publisher: name: Ri-Vista
Year: 2018

description: The system of waste processing currently exists as a linear process: trom cities of high densities to sprawling landscapes of waste, but as cities grow and densify, critical systems of waste infrastructure must be re-evaluated. Instead of today’s isolated and linear processes, urban and waste ecologies can become an interconnected and cyclical system. Current practic-es call for industrial processes to be pushed to the periphery of cities, thereby severing the rela-tionship between the urban environment we inhabit and the one that is required to support the way we live. If architects and designers become engaged in the conversation of waste manage-ment and other industrial processes that support the demands of the city, they can begin to re-pair the physical and mental separation of waste and public activity while introducing cultural, economic, and environmental value in waste infrastructure.

Year: 2018

description: Hiriya, a closed domestic waste landfill, is situated on the wide river plain in the southeast of Tel Aviv. The impressive landmark is part of the future Ariel Sharon Park. It is getting rehabilitated since 2004. Aim is to preserve its captivating silhouette and to develop the landscape of and around the mountain by using construction techniques that take into consideration the waste tip’s instability and make use of local materials whilst incorporating the region’s traditional land uses and specific climatic conditions. The artificial appearance of the landscape and its origins become a part of a positive experience of the site – a convergence of nature and culture.

Precision of future experiments measuring primordial tensor fluctuation

description: Recently the second phase of Background Imaging of Cosmic Extragalactic Polarization (BICEP2) claimed a detection of the tensor-to-scalar ratio ($r$) of primordial fluctuation at $5σ$ confidence level. If it is true, this large and measurable amplitude ($r \simeq 0.2$) of B-mode polarization indicates that it is possible to measure the shape of CMB B-mode polarization with future experiments. We forecast the precision of $r$ and the tensor spectral index $n_{\rm t}$ measurements, with $n_{\rm t}$ as a free parameter, from a {\it Planck}-like experiment, and from Spider and POLARBEAR given the current understanding of their experimental noise and foreground contamination. We quantitatively determine the signal-to-noise of the measurement in $r$-$n_{\rm t}$ parameter space for the three experiments. The forecasted signal-to-noise ratio of the B-mode polarization somewhat depends on $n_{\rm t}$, but strongly depends on the true value of $r$.

Tidal disruption of a star in the Schwarzschild spacetime: relativistic effects in the return rate of debris

description: Motivated by an improved multi-wavelength observational coverage of the transient sky, we investigate the importance of relativistic effects in disruptions of stars by non-spinning black holes (BHs). This paper focuses on calculating the ballistic rate of return of debris to the black hole as this rate is commonly assumed to be proportional to the light curve of the event. We simulate the disruption of a low mass main sequence star by BHs of varying masses ($10^5,10^6,10^7 M_\odot$) and of a white dwarf by a $10^5 M_\odot$ BH. Based on the orbital energy as well as angular momentum of the debris, we infer the orbital distribution and estimate the return rate of the debris following the disruption. We find two signatures of relativistic disruptions: a gradual rise as well as a delayed peak in the return rate curves relative to their Newtonian analogs. Assuming that the return rates are proportional to the light curves, we find that relativistic effects are in principle measurable given the cadence and sensitivity of the current transient sky surveys. Accordingly, using a simple model of a relativistic encounter with a Newtonian parametric fit of the peak leads to an overestimate in the BH mass by a factor of $\sim {\rm few}\times0.1$ and $\sim {\rm few}$ in the case of the main sequence star and white dwarf tidal disruptions, respectively.
