description: Group IV and V monolayers are the promising state-of-the-art 2D materials owing to their high carrier mobility, tunable bandgaps, and optical linear dichroism along with outstanding electronic and thermoelectric properties. Furthermore, recent studies reveal the stability of free-standing 2D monolayers by hydrogenation. Inspired by this, we systematically predict and investigate the structure and properties of various hydrogen saturated silicon phosphide (H-Si-P) monolayers, based on first-principles calculations. According to the results, H-Si-P monolayers belong to indirect bandgap semiconductors with a highly stable structure. Their bandgaps and band edge positions assessed using accurate hybrid functional are shown to be effectively adjusted by applying a biaxial strain. Furthermore, the absorption spectra of these monolayers, simulated in the context of time-dependent density functional theory, exhibit their excellent potential for solar energy conversion and visible-light-driven photocatalytic water splitting. In this respect, this work provides valuable guidance for finding more 2D semiconductors and nanostructures for nanoelectronic and optoelectronic applications, as well as for photocatalytic water splitting.

description: In recent years, a growing trend toward the decentralized financial system (DeFi) driven by blockchain and technological innovation put more emphasize on understanding of how the traditional financial system can encounter the ongoing and changing demands of a society evolving toward 4.0 and increasingly aiming to meet environmental, social, and governance sustainability criteria. To this aim, this paper provides a broad overview of blockchain technology, explores the DeFi ecosystem in the context of the current financial system, establishes a connection between DeFi and open banking, and offers some policy recommendations. Specifically, we aim to present all aspects of the corporate governance that can be improved through the adoption of decentralized form of blockchain technology to realize the full potential of the fourth industrial revolution. However, we also present the key drawbacks of blockchain that stakeholders should be aware of before implementing this technology. This paper further proposed a conceptual framework for adoption of blockchain technology capturing the complex relationships that exist between institutional, market and technical factors.  In this regard, we demonstrate how organisations and regulators can leverage blockchain to improve business operations, enhance efficiency and reduce operational costs. We also conclude that DeFi still is a niche market with certain risks, but it has great potential in terms of efficiency, transparency, accessibility, and interoperability. As such, it may contribute to the development of a more reliable and transparent financial infrastructure.

description: In this work, we studied the variable stars in the open cluster NGC 1912 based on the photometric observations and $Gaia$ DR2 data. More than 3600 CCD frames in B, V, R filters were reduced, and we obtained the light curves that span about 63 hours. By analyzing these light curves, we detected 24 variable stars, including 16 periodic variable stars, seven eclipsing binaries and one star whose type is unclear. Among these 24 variable stars, 11 are newly-discovered, which are classified as six gamma Doradus stars, one delta Scuti star, three detached binaries and one contact binaries. We also confirmed 13 previously known variable stars. Based on cluster members identified by Cantat-Gaudin et al. (2018), we inferred cluster memberships for these detected variable stars. Using Gaia DR2 data, we plotted a new color-magnitude diagram for NGC 1912, and showed the nature of variable cluster members in kinematical properties and heliocentric distance. Among the 24 variable stars, seven variables are probable cluster members, which show homogeneity in kinematic characters and space position with the established cluster members. Four of the seven variable cluster members are the previously discovered stars, consisting of two gamma Dor stars and two delta Sct stars. The remaining three variable cluster members, which are all gamma Dor stars, are firstly detected in this work. The main physical parameters of these variable cluster members estimated from the color-magnitude diagram are log(age/yr)=8.75, [Fe/H]=-0.1, m-M=10.03 mag, and E(B-V)=0.307.

description: Nitrogen is a biosignature gas that cannot be maintained in its Earth-like ratio with CO$_2$ under abiotic conditions. It has also proven to be notoriously hard to detect at optical and infrared wavelengths. Fortunately, the ultraviolet region, which has only recently started being explored for terrestrial exoplanets, may provide new opportunities to characterise exoplanetary atmospheric nitrogen. In this work, the future prospects for detecting atomic nitrogen absorption lines in the transmission spectrum of an Earth-like planet orbiting in the habitable zone of a Sun-like star with LUVOIR are explored. Using the non-local thermodynamic equilibrium spectral synthesis code Cloudy, we produce a far-ultraviolet atomic transmission spectrum for an Earth-Sun-like system, and identify several nitrogen features, including both N I and N II lines. We calculate the number of transits required for 1$σ$ and 3$σ$ detections of the planetary N{\sc i} $\lambda1200$ triplet signal with the G120M grating of the LUMOS spectrograph designed for LUVOIR, as a function of distance to the system and stellar ultraviolet emission. The minimum number of transit observations necessary for 1$σ$ and 3$σ$ detections of atomic N are 188 and 1685, respectively, for a system located at a distance of one pc with 100 times the Solar ultraviolet flux. Given that the orbital period of an Earth-Sun system is one year, it is not feasible to detect atomic N in the transmission spectrum for these systems. Future studies in this direction should therefore focus on Earth-like planets orbiting in the habitable zone of M dwarfs.

description: We calculate the dynamic structure factor S (omega, q) of spinless fermions in one dimension with quadratic energy dispersion k^2/2m and long range density-density interaction whose Fourier transform f_q is dominated by small momentum-transfers q << q_0 << k_F. Here q_0 is a momentum-transfer cutoff and k_F is the Fermi momentum. Using functional bosonization and the known properties of symmetrized closed fermion loops, we obtain an expansion of the inverse irreducible polarization to second order in the small parameter q_0 / k_F. In contrast to perturbation theory based on conventional bosonization, our functional bosonization approach is not plagued by mass-shell singularities. For interactions which can be expanded as f_q = f_0 + f_0^{2} q^2/2 + O (q^4) with finite f_0^{2} we show that the momentum scale q_c = 1/ | m f_0^{2} | separates two regimes characterized by a different q-dependence of the width gamma_q of the collective zero sound mode and other features of S (omega, q). For q_c << q << k_F we find that the line-shape in this regime is non-Lorentzian with an overall width gamma_q of order q^3/(m q_c) and a threshold singularity at the lower edge.

description: Tagged magnetic resonance imaging (MRI) is a widely used imaging technique for measuring tissue deformation in moving organs. Due to tagged MRI's intrinsic low anatomical resolution, another matching set of cine MRI with higher resolution is sometimes acquired in the same scanning session to facilitate tissue segmentation, thus adding extra time and cost. To mitigate this, in this work, we propose a novel dual-cycle constrained bijective VAE-GAN approach to carry out tagged-to-cine MR image synthesis. Our method is based on a variational autoencoder backbone with cycle reconstruction constrained adversarial training to yield accurate and realistic cine MR images given tagged MR images. Our framework has been trained, validated, and tested using 1,768, 416, and 1,560 subject-independent paired slices of tagged and cine MRI from twenty healthy subjects, respectively, demonstrating superior performance over the comparison methods. Our method can potentially be used to reduce the extra acquisition time and cost, while maintaining the same workflow for further motion analyses.

Legitimacy through public participation in risk policy making : a case study of water quality objectives for tritium in Ontario
Creators: name: Petersen, Fiona
Publisher: name: University of British Columbia
Year: 2009

description: The dominant social values and perceptions of the 1970s, which guided the development of institutional and procedural frameworks for risk policy making in Canada, have changed since that time. Over the last decade, the public has signalled problems with the perceived legitimacy of frameworks for risk policy making which involve closed negotiations between government and industry, and which rely heavily on the recommendations of a select group of scientific experts. Consequently, decision makers are adopting participatory policy making processes in attempts to restore public perceptions of legitimacy. This thesis examines the nature of public participation in risk policy making and evaluates the extent to which this type of approach, as it is designed in the context of a case study, addresses problems of legitimacy. On analyzing submissions from a public consultation on a drinking water guideline for tritium, it was found that decision makers failed to recognize the prevalence of legitimacy concerns, and thus did not design the process of public participation to address these issues. In employing a process of public involvement which resulted in no significant redistribution of influence over decision making, and in assuming that public concerns could be allayed by providing more technical information regarding risk assessment techniques, decision makers failed to recognize the changing social context for decision making on risk issues. If present trends in public values and perceptions continue, policy domains like that of radiation health protection, which employ closed, science-based decision processes, will be confronted with more pronounced problems of legitimacy which call for radical changes to both the social and the scientific assumptions which underlie risk policy making.

description: The calibration and analysis of polarization observations in Very Long Baseline Interferometry (VLBI) requires the use of specific algorithms that suffer from several limitations, closely related to assumptions in the data properties that may not hold in observations taken with new-generation VLBI equipment. Nowadays, the instantaneous bandwidth achievable with VLBI backends can be as high as several GHz, covering several radio bands simultaneously. In addition, the sensitivity of VLBI observations with state-of-the-art equipment may reach dynamic ranges of tens of thousands, both in total intensity and in polarization. In this paper, we discuss the impact of the limitations of common VLBI polarimetry algorithms on narrow-field observations taken with modern VLBI arrays (from the VLBI Global Observing System, VGOS, to the Event Horizon Telescope, EHT) and present new software that overcomes these limitations. In particular, our software is able to perform a simultaneous fit of multiple calibrator sources, include non-linear terms in the model of the instrumental polarization and use a self-calibration approach for the estimate of the polarization leakage in the antenna receivers.

description: Optical sensing is one of the key-enablers of modern diagnostics. Especially label-free imaging modalities hold great promise as they eliminate labeling procedures prior to analysis. However, scattering signals of nanometric particles scale with their volume-square. This unfavorable scaling makes it extremely difficult to quantitatively characterize intrinsically heterogeneous clinical samples, such as extracellular vesicles, as their signal variation easily exceeds the dynamic range of currently available cameras. Here, we introduce off-axis k-space holography that circumvents this limitation. By imaging the back-focal-plane of our microscope we project the scattering signal of all particles onto all camera pixels thus dramatically boosting the achievable dynamic range to up-to 110 dB. We validate our platform by detecting, and quantitatively sizing, metallic and dielectric particles over a 200x200 $μ$m field-of-view and demonstrate that independently performed signal calibrations allow correctly sizing particles made from different materials. Finally, we present quantitative size-distributions of extracellular vesicle samples.
Supersymmetry, Naturalness, and Signatures at the LHC

description: Weak scale supersymmetry is often said to be fine-tuned, especially if the matter content is minimal. This is not true if there is a large A term for the top squarks. We present a systematic study on fine-tuning in minimal supersymmetric theories and identify low energy spectra that do not lead to severe fine-tuning. Characteristic features of these spectra are: a large A term for the top squarks, small top squark masses, moderately large tanβ, and a small μparameter. There are classes of theories leading to these features, which are discussed. In one class, which allows a complete elimination of fine-tuning, the Higgsinos are the lightest among all the superpartners of the standard model particles, leading to three nearly degenerate neutralino/chargino states. This gives interesting signals at the LHC -- the dilepton invariant mass distribution has a very small endpoint and shows a particular shape determined by the Higgsino nature of the two lightest neutralinos. We demonstrate that these signals are indeed useful in realistic analyses by performing Monte Carlo simulations, including detector simulations and background estimations. We also present a method that allows the determination of all the relevant superparticle masses without using input from particular models, despite the limited kinematical information due to short cascades. This allows us to test various possible models, which is demonstrated in the case of a model with mixed moduli-anomaly mediation. We also give a simple derivation of special renormalization group properties associated with moduli mediated supersymmetry breaking, which are relevant in a model without fine-tuning.

description: It is a commonly held belief that a consistent dimensional reduction ansatz can be equally well substituted into either the higher-dimensional equations of motion or the higher-dimensional action, and that the resulting lower-dimensional theories will be the same. This is certainly true for Kaluza-Klein circle reductions and for DeWitt group-manifold reductions, where group-invariance arguments guarantee the equivalence. In this paper we address the question in the case of the non-trivial consistent Pauli coset reductions, such as the S^7 and S^4 reductions of eleven-dimensional supergravity. These always work at the level of the equations of motion. In some cases the reduction ansatz can only be given at the level of field strengths, rather than the gauge potentials which are the fundamental fields in the action, and so in such cases there is certainly no question of being able to substitute instead into the action. By examining explicit examples, we show that even in cases where the ansatz can be given for the fundamental fields appearing in an action, substituting it into the higher-dimensional action may not give the correct lower-dimensional theory. This highlights the fact that much remains to be understood about the way in which Pauli reductions work.

description: Background: The Ireland North and South Report Card on Physical Activity (PA) for Children and Adolescents aims to monitor progress in PA participation across a range of internationally established indicators.Methods: Data were collated for 11 indicators and graded following the harmonised Active Healthy Kids Global Alliance report card process. Six representative studies (sample size range n = 898 to n = 15,557) were primarily used in the grading, with many indicators supplemented with additional studies and reports. Data collected since the implementation of COVID-19 public health measures in March 2020 were excluded.Results: Grades were awarded as follows: ‘Overall physical activity’, C-; ‘Organised Sport and Physical Activity’, C; ‘Active Play’, INC; ‘Sedentary Behaviours’, C-; ‘Physical Fitness’, INC; ‘Family and Peers’, D+; ‘School’, C-; ‘Physical Education’, D; ‘Community and Environment’, B+ and ‘Government’, B. Separate grades were awarded for disability as follows; ‘Overall physical activity’, F; ‘Organised Sport and Physical Activity’, D; ‘Sedentary Behaviours’, C-; ‘Family and Peers’, C; ‘School’, C- and ‘Government’, B. ‘Active Play’, ‘Physical Fitness’, ‘Physical Education’ and ‘Community and Environment’ were all graded INC for disability. Since the last report card in 2016, four grades remained the same, three increased (‘Overall physical activity’, ‘School’ and ‘Physical Education’) and two (‘Family and Peers,’ and ‘Government’) were awarded grades for the first time. Conclusion: Grades specific to children and adolescents with disability were generally lower for each indicator. While small improvements have been shown across a few indicators, PA levels remain low across many indicators for children and adolescents.

description: The manganese tellurate Li2MnTeO6 consists of trigonal spin lattices made up of Mn4+ (d3, S = 3/2) ions. The magnetic properties of this compound were characterized by several experimental techniques, which include magnetic susceptibility, specific heat, dielectric permittivity, electron spin resonance (ESR), nuclear magnetic resonance (NMR) and neutron powder diffraction (NPD) measurements, and by density functional calculations (DFT). The magnetic susceptibility chi(T) demonstrates very unusual behavior. It isdescribed by the Curie-Weiss law at high temperature with Curie-Weiss temperature of Theta = -74 K, exhibits no obvious anomaly indicative of a long-range magnetic ordering at low magnetic fields. At high magnetic fields, however, the character of chi(T) changes showing a maximum at about 9 K. That this maximum of chi(T) reflects the onset of an antiferromagnetic order was confirmed by specific heat measurements, which exhibit a clear lambda-type anomaly at TN around 8.5 K even at zero magnetic field, and by 7Li NMR and dielectric permittivity measurements. The magnetic structure of Li2MnTeO6, determined by neutron powder diffraction measurements at 1.6 K, is described by the 120-degree non-collinear spin structure with the propagation vector k = (1/3, 1/3, 0). Consistent with this finding, the spin exchange interactions evaluated for Li2MnTeO6 by density functional calculations are dominated by the nearest-neighbor antiferromagnetic exchange within each triangular spin lattice. This spin lattice is strongly spin frustrated with f = |Theta|/TN around 8 and exhibits a two-dimensional magnetic character in a broad temperature range above TN.

description: We extract the $Q$-$\bar Q$ potential by using the thermodynamic quantities obtained in lattice gauge calculations. The potential is tested and found to give dissociation temperatures that agree well with those from lattice gauge spectral function analysis. Using such a $Q$-$\bar Q$ potential, we examine the quarkonium states in a quark-gluon plasma and determine the `quark drip lines' which separate the region of bound color-singlet $Q\bar Q$ states from the unbound region. The characteristics of the quark drip lines severely limit the region of possible bound $Q\bar Q$ states with light quarks to temperatures close to the phase transition temperature. Bound quarkonia with light quarks may exist very near the phase transition temperature if their effective quark mass is of the order of 300-400 MeV and higher.

description: Wavefront sensing from an extended object is a challenging task since the phase to be sensed is disturbed by the phase generated from the structure of the extended object. To address this problem, a general wavefront sensor was proposed. The hardware of the sensor consists of a field lens, a collimating lens, a lenslet array, and a camera. The idea for its algorithm is to eliminate the phase caused by the extended object and reconstruct the point spread function through each lenslet. As a result, the scenario of wavefront sensing from an extended object has been converted to the conventional one from a point source. Numerical simulations and experiments both verify the feasibility and the accuracy of the proposed sensor.

We investigate the prospects of measuring the polarizability functions for pion-Compton c.m. energies from threshold up to 1 GeV. A meson-exchange model is used for the pion-Compton amplitude.

In such a state vortices do not form a simple lattice but arrange themselves in clusters, within which the vortices are partially delocalized, tunneling between classically degenerate configurations. We demonstrate that this exotic quantum many-body state is selected by an order-from-disorder mechanism for a special combination of the vortex filling and lattice geometry that has a macroscopic number of classically degenerate ground states.

description: Single photons from solid-state quantum emitters are playing a crucial role in the development of photonic quantum technologies. Higher order states, such as N-photon Fock-states allow for applications e.g. in quantum-enhanced sensing. In this study, we utilize the dispersion of a hot cesium vapor at the D1 lines to realize a temporal delay for one and two-photon Fock-states as a result of the slow-light effect. Single photons are generated on-demand from an InGaAs quantum dot, while their quantum interference at a beam splitter is used to generate a two-photon Fockstate. We verify the successful propagation and temporal delay of both the one and two-photon Fock-states, while a significant delay (5x initial photon length) with simultaneous high transmission (~90 %) is achieved.

description: Electron-positron pair cascades developed in the extreme electromagnetic fields of neutron star polar caps are considered a key source of magnetospheric plasma in these objects. We use a simplified model that maps the Quantum Electrodynamics processes governing the pair cascades to analytically and numerically model the development of the pair cascade, and show that large-amplitude oscillations of the electric field are inductively driven by the resulting plasma. A plasma instability arises in these oscillations, and particles accelerated in growing electric field perturbations can drive secondary pair bursts that damp the large-amplitude oscillations. An analytical model is proposed to describe this interplay between the pair production and kinetic collective plasma processes. All analytical results are shown to be in excellent agreement with particle-in-cell simulations.

description: We present chemical abundances for planetary nebulae and H II regions in the Local Group dwarf irregular galaxy NGC 6822 based upon spectroscopy obtained at the Canada-France-Hawaii Telescope using the Multi-Object Spectrograph. From these and similar data compiled from the literature for planetary nebulae in the Magellanic Clouds, Sextans A, Sextans B, and Leo A, we consider the origin and evolution of the stellar progenitors of bright planetary nebulae in dwarf irregular galaxies. On average, the oxygen abundance observed in the bright planetary nebulae in these galaxies coincides with that measured in the interstellar medium, indicating that, in general, the bright planetary nebulae in dwarf irregulars descend primarily, though not exclusively, from stars formed in the relatively recent past. We also find that the ratio of neon to oxygen abundances in these bright planetary nebulae is identical to that measured in the interstellar medium, indicating that neither abundance is significantly altered as a result of the evolution of their stellar progenitors. We do find two planetary nebulae, that in Sextans A and S33 in NGC 6822, where oxygen appears to have been dredged up, but these are the exception rather than the rule. In fact, we find that even nitrogen is not always dredged up, so it appears that the dredge-up of oxygen is uncommon for the abundance range of the sample.

description: Measurements of cosmic microwave background (CMB) anisotropies by interferometers offer several advantages over single-dish observations. The formalism for analyzing interferometer CMB data is well developed in the flat-sky approximation, valid for small fields of view. As the area of sky is increased to obtain finer spectral resolution, this approximation needs to be relaxed. We extend the formalism for CMB interferometry, including both temperature and polarization, to mosaics of observations covering arbitrarily large areas of the sky, with each individual pointing lying within the flat-sky approximation. We present a method for computing the correlation between visibilities with arbitrary pointing centers and baselines and illustrate the effects of sky curvature on the l-space resolution that can be obtained from a mosaic.

description: Anti-reflective coatings (ARCs) are used on the vast majority of solar photovoltaic (PV) modules to increase power production. However, ARC longevity can vary from less than 1 year to over 15 years depending on coating quality and deployment conditions. A technique that can quantify ARC degradation non-destructively on commercial modules would be useful both for in-field diagnostics and accelerated aging tests. In this paper, we demonstrate that accurate measurements of ARC spectral reflectance can be performed using a modified commercially-available integrating-sphere probe. The measurement is fast, accurate, non-destructive and can be performed outdoors in full-sun conditions. We develop an interferometric model that estimates coating porosity, thickness and fractional area coverage from the measured reflectance spectrum for a uniform single-layer coating. We demonstrate the measurement outdoors on an active PV installation, identify the presence of an ARC and estimate the properties of the coating.

Gastric evacuation rates in Rainbow Trout (Oncorhynchus mykiss) fed different diets

description: The passage time of ingested food through the digestive tract affects the appropriate timing of meals and the amount of feed that can be consumed. The rate of digestion of dietary components and the efficiency with which nutrients are absorbed may also be affected by passage time. The present study examined the effects of different dietary concentrations of fibre, lipid and gelatin on the rate of food passage in rainbow trout reared in fresh and salt water. Different ingredients were added to diets in two separate experiments. Feed conversion rates for these diets were determined. The effect of these ingredients on the rate of passage was determined through timed dissections of the stomach and intestine of rainbow trout. The contents were weighed and, in experiment 2, the water content determined. In experiment 1, feeding trials involving three experimental diets and one control diet were conducted. The control diet contained 8% lipid and no fibre additions. The experimental diets were: a 20% lipid diet, 12% pectin diet and a 12% cellulose diet. The pectin diet resulted in poor feed consumption and growth, indicating that an attribute of the diet, taste or texture, was disliked by the fish. The high lipid diet had the best feed conversion while the diet containing cellulose resulted in poor feed conversion. In Experiment 2, both a fresh water and a salt water location were used. Four different dietary treatments were imposed on fish in the fresh water location: a basal diet (control); the basal diet containing 10% gelatin; the basal diet containing an additional %10 of oil ; and, a basal diet containing 10% cellulose and an additional 8% of oil . At the salt water location, diets were similar except the omission of the diet containing gelatin. The effects of the dietary additions on the movement of ingesta through the stomach and intestine were determined for each diet at each site . The percentages of water in the ingesta in the stomachs were compared to determine if there were differences when fish are grown in a saltwater environment as compared to when they are grown i n a freshwater environment. In both experiment 1 and experiment 2, the addition of cellulose to the basal diet, (Diet 4) increased the rate of passage during the initial 12 hours after feeding. Consumption of the diet containing cellose was greater than that of the other experimental diets. An increased consumption of diets with a cellulose addition concurs with the findings reported in the literature . The increased evacuation rate, however, is contrary to previous findings. The high lipid diets evacuated slowly for the first 6 hours and then rapidly after that time. There was a significantly higher water concentration in the stomach contents in the fish reared in salt water than in the fish reared in fresh water. The drinking of salt water by fish affects the rate of evacuation from the stomach, decreasing the time the ingesta takes to pass through the gastrointestinal tract.
Interacting holographic dark energy model and generalized second law of thermodynamics in non-flat universe

description: In the present paper we consider the interacting holographic model of dark energy to investigate the validity of the generalized second laws of thermodynamics in non-flat (closed) universe enclosed by the event horizon measured from the sphere of the horizon named $L$. We show that for $L$ as the system's IR cut-off the generalized second law is respected for the special range of the deceleration parameter.

Remarks. The type locality for A. armata is Singapore (Hardwicke & Gray 1827) (Table 1), based on two specimens from Hardwicke’s collection and one from Argent’s collection (Gray 1845). Flower (1899) expressed doubts of A. armata occurring in Singapore citing ambiguity with the location of some of Hardwicke’s specimens and that no further specimens were reported. Lim & Chou (1990) and Baker & Lim (2008) followed Flower’s (1899) opinion and listed A. armata as doubtful in their checklists. In Peninsular Malaysia, A. armata occurs at the upper elevations of hilly and mountainous dipterocarp forest up to 810 m (Grismer 2011a, b). However, in the Seribuat Archipelago, it can be found at all elevations (Grismer 2011a). Given the uncertainty of the localities of the Hardwicke and Argent specimens, and its habitat requirements in Peninsular Malaysia, we classify A. armata as erroneous. Consequently, we suggest the type locality should be changed to Penang, Malaysia, where the subsequent specimens were collected by Cantor (Cantor 1847; Boulenger 1885).

description: We verify explicitly that UV/IR mixing for noncommutative gauge theory can be understood in terms of an induced gravity action, as predicted by the identification [1] of gravity within matrix models of NC gauge theory. More precisely, we obtain the Einstein-Hilbert action by integrating out a scalar field in the adjoint. It arises from the well-known UV/IR mixing of NC gauge theory, which is carefully re-analyzed and interpreted in terms of gravity. The matrix model therefore contains gravity as an IR effect, due to UV/IR mixing.
