Beach morphodynamics under sequences of high and low energy wave conditions
Creators: name: Eichentopf, Sonja
Publisher: name: Imperial College London
Year: 2020

description: This thesis studies the morphodynamic evolution of beach profiles under high and low energy wave conditions using large-scale laboratory and long-term field measurements. This work presents an important contribution towards a better understanding of beach profile evolution under varying wave conditions, including storm sequences and the relevance of the antecedent beach morphology. First, beach profile evolution is studied using several large-scale data sets comprising one high energy (storm) followed by one low energy wave condition. These data support the traditional understanding of high and low energy wave conditions leading to beach erosion and recovery, respectively. However, existing literature has postulated that several storms in quick succession (storm sequences) have a greater potential for erosion, as the beach has less time to recover. Consequently, the RESIST data set is studied to explore beach profile evolution under storm sequence conditions. This data set comprises three storm sequences, which each consist of two storms followed by subsequent low energy conditions. Overall, in contrast to previous findings, no enhanced beach erosion due to storm sequencing is observed. The beach evolves towards an equilibrium configuration that is specific to each wave condition. This implies that the same wave condition can generate bulk onshore or offshore sediment transport, depending on the antecedent beach morphology. The antecedent morphology is shown to be very important for the hydrodynamic-morphological coupling that leads to an equilibrium configuration: while a large breaker bar promotes wave energy dissipation, sheltering the beach and limiting shoreline erosion, a beach profile with a small bar allows waves to propagate further onshore, resulting in erosion of the large swash berm. Finally, the occurrence and influence of storm sequencing on beach profile evolution are studied using long-term field measurements from Hasaki Beach, Japan. Hasaki Beach is subjected to frequent storms that often cluster in sequences. Despite a tendency for storms and storm sequences with larger power to cause more erosion, the present data set does not demonstrate increased beach erosion by storm sequences. In fact, it is shown that some storms and storm sequences can also result in recovery of the beach. Following these findings, the tendency of the beach to evolve towards equilibrium and the importance of the antecedent beach morphology are demonstrated.

As an application, we prove Hardy inequality with an extra term for the fractional Laplacian on the interval with the optimal constant. As a result, we obtain the fractional Hardy inequality with best constant and an extra lower-order term for general domains, following the method developed by M. Loss and C.

description: The aviation industry as well as the industries that benefit and are linked to it are ripe for innovation in the form of Big Data analytics. The number of available big data technologies is constantly growing, while at the same time the existing ones are rapidly evolving and empowered with new features. However, the Big Data era imposes the crucial challenge of how to effectively handle information security while managing massive and rapidly evolving data from heterogeneous data sources. While multiple technologies have emerged, there is a need to find a balance between multiple security requirements, privacy obligations, system performance and rapid dynamic analysis on large datasets. The current paper aims to introduce the ICARUS Secure Experimentation Sandbox of the ICARUS platform. The ICARUS platform aims to provide a big data-enabled platform that aspires to become an 'one-stop shop' for aviation data and intelligence marketplace that provides a trusted and secure 'sandboxed' analytics workspace, allowing the exploration, integration and deep analysis of original and derivative data in a trusted and fair manner. Towards this end, a Secure Experimentation Sandbox has been designed and integrated in the ICARUS platform offering, that enables the provisioning of a sophisticated environment that can completely guarantee the safety and confidentiality of data, allowing to any interested party to utilise the platform to conduct analytical experiments in closed-lab conditions.

description: The transmission of a Gaussian source over a block-fading multiple antenna channel in the presence of a feedback link is considered. The feedback link is assumed to be an error and delay free link of capacity 1 bit per channel use. Under the short-term power constraint, the optimal exponential behavior of the end-to-end average distortion is characterized for all source-channel bandwidth ratios. It is shown that the optimal transmission strategy is successive refinement source coding followed by progressive transmission over the channel, in which the channel block is allocated dynamically among the layers based on the channel state using the feedback link as an instantaneous automatic repeat request (ARQ) signal.

description: When an electron or a hole is added into an orbital of an adsorbed molecule the substrate electrons will rearrange in order to screen the added charge. This results in a reduction of the electron addition/removal energies as compared to the free molecule case. In this work we use a simple model to illustrate the universal trends of this renormalization mechanism as a function of the microscopic key parameters. Insight of both fundamental and practical importance is obtained by comparing GW quasiparticle energies with Hartree-Fock and Kohn-Sham calculations. We identify two different polarization mechanisms: (i) polarization of the metal (image charge formation) and (ii) polarization of the molecule via charge transfer across the interface. The importance of (i) and (ii) is found to increase with the metal density of states at the Fermi level and metal-molecule coupling strength, respectively.

description: The unprecedented volume, diversity and richness of aviation data that can be acquired, generated, stored, and managed provides unique capabilities for the aviation-related industries and pertains value that remains to be unlocked with the adoption of the innovative Big Data Analytics technologies. Despite the large efforts and investments on research and innovation, the Big Data technologies introduce a number of challenges to its adopters. Besides the effective storage and access to the underlying big data, efficient data integration and data interoperability should be considered, while at the same time multiple data sources should be effectively combined by performing data exchange and data sharing between the different stakeholders. However, this reveals additional challenges for the crucial preservation of the information security of the collected data, the trusted and secure data exchange and data sharing, as well as the robust data access control. The current paper aims to introduce the ICARUS big data-enabled platform that aims provide a multi-sided platform that offers a novel aviation data and intelligence marketplace accompanied by a trusted and secure analytics workspace. It holistically handles the complete big data lifecycle from the data collection, data curation and data exploration to the data integration and data analysis of data originating from heterogeneous data sources with different velocity, variety and volume in a trusted and secure manner.

description: We report results of our analysis of the Kepler superaperture LC data of the open cluster NGC6791 to search for pulsating sdB stars. We checked all pixels and we found only three sdB stars to be pulsating, KIC2569576 (B3), KIC2438324 (B4) and KIC2437937 (B5). These stars were known to be pulsators before, though we extended data coverage detecting more frequencies and features in their amplitude spectra, i.e. new multiplets and more complete period spacing sequences that we used for identifying geometry of the pulsation modes. The multiplet splittings were also used to derive rotation periods. The remaining known sdBs do not show any pulsation-related light variation down to our detection thresholds. We analyzed already existing spectroscopic observations taken with the HECTOSPEC at the MMT telescope in Smithsonian Arizona and with the GMOS at the Gemini North telescope, and fitted atmospheric parameters using the Balmer lines. Four stars, B3-B6, show atmospheric parameters that are consistent with g-mode dominated sdBs. We detected hints of radial velocity variability in B3, B5, and B6, indicating these three stars may be in binaries.

Quantum-Criticality in Dissipative Quantum Two-Dimensional XY and Ashkin-Teller Models: Application to the Cuprates

description: In a recent paper [V. Aji and C.M. Varma, Phys. Rev. Lett. {\bf 99}, 167003 (2007) \cite{aji1}] we have shown that the dissipation driven quantum phase transition of the 2D xy model represents a universality class where the correlations at criticality is local in space and power law in time. Here we provide a detailed analysis of the model. The local criticality is brought about by the decoupling of infrared singularities in space and time. The former leads to a Kosterlitz Thouless transition whereby the excitations of the transverse component of the velocity field (vortices) unbind in space. The latter on the other hand leads to a transition among excitations (warps) in the longitudinal component of the velocity field, which unbind in time. The quantum Ashkin-Teller model, with which the observed loop order in the Cuprates is described maps in the critical regime to the quantum xy model. We also discuss other models which are expected to have similar properties.

description: In 2017, the first image of the center of the M87 galaxy was captured by the Event Horizon Telescope (EHT). It revealed a ring morphology and a size consistent with theoretical expectations for the light pattern around a weakly accreting supermassive black hole of ~6.5 billion solar masses. In parallel to the EHT measurements, an extensive multi-wavelength (MWL) campaign with ground- and space-based facilities from radio all the way up to the TeV energy range was organized. In this note we will give an overview of the results from this campaign. M87 was found to be in a historically low state. At X-ray energies the emission from the core dominates over HST-1. We present the most complete simultaneous, MWL spectrum of the active nucleus to date.

description: Recent observational evidence has demonstrated that white dwarf (WD) mergers are a highly efficient mechanism for mass accretion onto WDs in the galaxy. In this paper, we show that WD mergers naturally produce highly-magnetized, uniformly-rotating WDs, including a substantial population within a narrow mass range close to the Chandrasekhar mass ($M_{\rm Ch}$). These near-$M_{\rm Ch}$ WD mergers subsequently undergo rapid spin up and compression on a $\sim 10^2$ yr timescale, either leading to central ignition and a normal SN Ia via the DDT mechanism, or alternatively to a failed detonation and SN Iax through pure deflagration. The resulting SNe Ia and SNe Iax will have spectra, light curves, polarimetry, and nucleosynthetic yields similar to those predicted to arise through the canonical near-$M_{\rm Ch}$ single degenerate (SD) channel, but with a $t^{-1}$ delay time distribution characteristic of the double-degenerate (DD) channel. Furthermore, in contrast to the SD channel, WD merger near-$M_{\rm Ch}$ SNe Ia and SNe Iax will not produce observable companion signatures. We discuss a range of implications of these findings, from SNe Ia explosion mechanisms, to galactic nucleosynthesis of iron peak elements including manganese.

description: We reanalyse the measurements of parallax, proper motion, and line-of-sight velocity for 18 masers in high mass star-forming regions presented by Reid et al. (2009). We use a likelihood analysis to investigate the distance of the Sun from the Galactic centre, R_0, the rotational speed of the local standard of rest, v_0, and the peculiar velocity of the Sun, vsol, for various models of the rotation curve, and models which allow for a typical peculiar motion of the high mass star-forming regions. We find that these data are best fit by models with non-standard values for vsol or a net peculiar motion of the high mass star-forming regions. We argue that a correction to vsol is much more likely, and that these data support the conclusion of Binney (2009) that V_sol should be revised upwards from 5.2 km/s to 11 km/s. We find that the values of R_0 and v_0 that we determine are heavily dependent on the model we use for the rotation curve, with model-dependent estimates of R_0 ranging from 6.7 \pm 0.5kpc to 8.9 \pm 0.9kpc, and those of v_0 ranging from 200 \pm 20 km/s to 279 \pm 33 km/s. We argue that these data cannot be thought of as implying any particular values of R_0 or v_0. However, we find that v_0/R_0 is better constrained, lying in the range 29.9-31.6 km/s/kpc for all models but one.

SOFT POWER REVISITED: HOW ATTRACTION WORKS IN INTERNATIONAL RELATIONS
Creators: name: PATALAKH, ARTEM
Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: This thesis problematises the bases of soft power, that is, causal mechanisms connecting the agent (A) and the subject (B) of a power relationship. As the literature review reveals, their underspecification by neoliberal IR scholars, the leading proponents of the soft power concept, has caused a great deal of scholarly confusion over such questions as how to clearly differentiate between hard and soft power, how attraction (soft power?s primary mechanism) works and what roles structural and relational forces play in hard/soft power. In an effort to ascertain the bases, I address this issue not from the viewpoint of A?s policies or resources, like do IR neoliberal scholars, but in terms of B?s psychological perception of A. Employing social psychological accounts, I argue that attraction can be produced in three distinct ways, namely 1) through B?s identification with A (?emotional? attraction), 2) via B?s appreciation of A?s competence/knowledge in a particular field (?rational? attraction) and 3) by means of the activation of B?s internalised values which contextually prescribe B to act in A?s favour (?social? attraction). Importantly, depending upon the way attraction is produced, it is peculiar in a number of characteristics, the main of which are power scope, weight and durability. Insights from social psychology also show that unlike soft power, hard power requires not only B?s relevant perception of the A-B relationship (as coercive or rewarding), but also A?s capability to actualise a threat of punishment and/or a promise of reward. I argue this difference can be fairly treated as definitional rather than empirical, which implies that coercion and reward necessarily have both relational and structural dimensions, whereas for attraction, a structural one alone suffices, while a relational one may or may not be present. Having explicated the soft power bases, I illustrate each of them using three ?most likely? case studies, namely Serbia?s policies towards Russia (emotional attraction), Kazakhstan?s approach to relations with the EU (rational attraction) and Germany?s policies vis-�-vis Israel (social attraction).

description: Using a first principles linear response approach, we study the magnetic exchange interactions J for a series of superconducting cuprates. We reproduce the observed spin-wave dispersions together with other experimental trends, and show that different cuprates have similar J's regardless their T$_{c}$. The nearest neighbor J is not sensitive to the hole-doping, which agrees with recent experiments. For the undoped cuprates, the second nearest neighbor J is ferromagnetic, but changes its sign with hole-doping. We also find that, in contrast to the hopping integral, the exchange interaction is not sensitive to the position of apical oxygen. To see the effect of the long--range nature of the exchange on the superconducting T$_{c}$, we study the dynamical spin susceptibility $χ(q,ω)$ within the t--J model using a dynamical cluster approximation.

THE DEVELOPMENTAL LOGIC OF ENHANCEROPATHIES CAUSED BY KMT2D AND YY1 HAPLOINSUFFICIENCY THROUGH PATIENT-DERIVED DISEASE MODELING PLATFORMS
Creators: name: GABRIELE, MICHELE
Publisher: name: Universit� degli Studi di Milano

description: The human brain is generated by developmental events orchestrated by fine-tuned transcriptional events. The vulnerability of this process is highlighted by the fact that environmental insults in early stages of development, or germline mutations in chromatin remodelers, often lead to neurodevelopmental disorders. An historical challenge for studying neurodevelopmental disorders has been the lack of reliable human platforms. Nowadays, technological advancements allowed us to use human cellular models to study the neurons and the molecular implications of specific mutations. In this work is described a human modeling platform of Kabuki Syndrome, caused by germline mutations in the enzyme KMT2D, which is involved in enhancer activation, and of Gabriele-de Vries syndrome, caused by mutations in YY1, which mediates DNA looping between gene promoters and enhancers. These two diseases thus belong to the class of enhanceropathies. Using induced pluripotent stem cells and their differentiation in disease-relevant cell types such as neural crest stem cells and cortical excitatory neurons, it was possible to identify molecular and functional phenotypes unique to Kabuki syndrome that contribute to the understanding of its molecular pathogenesis. Moreover, starting from genetic observations of individuals with intellectual disabilities who lacked a molecular diagnosis, YY1 was identified as the mutated gene responsible for a novel neurodevelopmental disorder, which is caused by an improper regulation of transcriptional enhancers. The synergic study of enhanceropathies may lead to the identification of altered gene regulatory networks, convergent to common targets, responsible for shared clinical features, thus paving the way for the identification of shared actionable pathways.
Resistance and accommodation in a racial polity : responses of Indian South Africans
Creators: name: Adam-Moodley, Kogila
Publisher: name: University of British Columbia
Year: 2010

description: This thesis attempts to analyse the ways in which, a minority responds to varying situations of oppression in a racially structured environment. In order to explicate what constitutes oppression, an historical survey of major legislation affecting Indians in South Africa is outlined. This reveals different techniques used by the dominant group to ward off challenges to its power by counter elites, from direct suppression to neutralisation and co-optation. The reactions of Indians to these changes,and the impact of these responses on their relationship with the dominant group as well as with other subordinate groups at the political, economic, educational and social level guides the focus of this investigation. More specifically, the political behaviour of Indians is examined, (a) in alliance and conflicts with other subordinate groups, particularly Africans, (b) in developing complementary interests with some members of the superordinate group, (c) in. intra-' communal class or status-group based divisions and factions, and (d) in political introversion and inactivity through cultural exclusivism and cultural immersion. Research procedures used during three periods of field work in Natal included the recording of 86 informal interviews, the content analysis of various official and private documents on Indian affairs^nd the collection of essays written by 65 Indian university students as so-called "future autobiographies". The major literature on race relations and minority behaviour in other societal contexts is critically reviewed regarding the applicability of its concepts and models to the South African case. The political behaviour of Indians would seem to indicate how the dialectic of resistance and acquiescence operates in particular historical circumstances. Indeed, neither class consciousness nor ethnicity in themselves constitute satisfactory concepts for generalizations and predictions. Which bond is successfully activated would seem to depend on the specific historical context and perceptions of interest. These proved to have undergone considerable changes, according to the emerging social stratification of the group, despite the common experience of racial discrimination. Predominant Indian political reactions under future majority rule in an African-dominated government would above all depend on the as yet unpredictable policies at that stage, the degree of animosity experienced, and the kind of security awarded to the vulnerable and, therefore, ambivalent, suspicious -"strangers" in between.

description: Am Sonntag, den 24. Oktober 2021, wurde der simbabwischen Autorin und Filmemacherin Tsitsi Dangarembga der Friedenspreis des Deutschen Buchhandels verliehen. In ihren Werken setzt sie sich literarisch und cineastisch mit der Situation von Frauen in Simbabwe auseinander. Auch im realen Leben erhebt sie ihre Stimme.

Ihr frauen- und menschenrechtliches Engagement im postkolonialen Simbabwe, einem 1980 unabhängig gewordenen Staat im südlichen Afrika (Marx 2017), gilt politisch Verfolgten, die unter einem repressiven Regime (Schäfer 2012) sowie einer seit Jahren andauernden ökonomischen Abwärtsspirale täglich um ihre Existenz kämpfen müssen. Drakonische Gesetze und deren willkürliche Auslegung brachten insbesondere während der Corona-Krise und einem von Militär und Polizei kontrollierten Lockdown viele zivilgesellschaftliche Aktive in bereits überfüllte und völlig desolate Gefängnisse (Schäfer 2020).

Mit einem persönlichen Protest gegen die institutionalisierte Korruption forderte Tsitsi Dangarembga am 31. Juli 2020 Situationsverbesserungen (siehe Interview im ZDF). Umgehend wurde sie festgenommen, ihr wird Anstiftung zu öffentlicher Gewalt vorgeworfen. Im Dezember muss sie sich wieder vor Gericht verantworten, es ist die zehnte Anhörung.

Approaching a strong fourth family

description: A heavy fourth family is an example of new physics which is well defined and familiar in some respects, but which nevertheless has radical implications. In particular it eliminates a light Higgs description of electroweak symmetry breaking. We discuss an early signal for heavy quarks at the LHC in the form of an excess of "$W$-jets", and as well show how $W$-jets may be useful in the reconstruction of the heavy quark masses. We argue that fourth family quarks can be distinguished from vector-like quarks of a similar mass at roughly the same time that a same sign lepton signal becomes visible. Given the large mass of the fourth neutrino we describe how a picture for neutrino mass emerges in the absence of right-handed neutrinos, and how it suggests the existence of a remnant flavor gauge symmetry. Based on talk given at "Second Workshop on Beyond 3 Generation Standard Model -- New Fermions at the Crossroads of Tevatron and LHC", January 2010, Taipei Taiwan.

description: We describe active asteroid 331P/Gibbs (2012 F5) using archival Hubble Space Telescope data taken between 2015 and 2018. 331P is an outer main-belt active asteroid with a long-lived debris trail that formed in 2011. Embedded in the debris trail we identify 19 fragments with radii between 0.04 and 0.11 km (albedo 0.05 assumed) containing about 1 percent of the mass of the primary nucleus. The largest shows a photometric range (1.5 magnitudes), a V-shaped minimum and a two-peaked lightcurve period near 9 hours, consistent with a symmetric contact binary (Drahus and Waniak 2016). Less convincing explanations are that 331P-A is a monolithic, elongated splinter or that its surface shows hemispheric 4:1 albedo variations. The debris trail is composed of centimeter sized and larger particles ejected with characteristic 10 cm s$^{-1}$ speeds following a size distribution with index q = 3.7+/-0.1 to 4.1+/-0.2. The HST data show that earlier, ground-based measurements of the nucleus were contaminated by near-nucleus debris, which cleared by 2015. We find that the primary nucleus has effective radius 0.8+/-0.1 km and is in rapid rotation (3.26+/-0.01 hour, range 0.25 magnitudes, minimum density 1600 kg/m3 if strengthless. The properties of 331P are consistent with a) formation about 1.5 Myr ago by impact shattering of a precursor body (Novakovic et al. 2014) b) spin-up by radiation torques to critical rotation c) ejection of about 1 percent of the nucleus mass in mid-2011 by rotational instability and d) subsequent evolution of the fragments and dispersal of the debris by radiation pressure.

description: The effects of two SAR inducers (benzothiadiazole and chitosan) were investigated on volatile isoprenoid (mono- and sesquiterpene) and phytosterol (?-sitosterol, stigmasterol and campesterol) content in a grapevine cultivar (Groppello, autochthonous of Lombardy) and in its respective experimental wines. The efficacy of plant activators has been also assayed on the control of the potentially toxigenic grape mycoflora, by measuring the mycotoxin levels in wines.
Non-BCS behavior of optical properties across the cuprate phase diagram

description: The finite-frequency optical properties of the underdoped cuprates, in both the normal and superconducting state, display features which go beyond a Fermi liquid and a BCS description. We provide an understanding of these properties within a simplified analytical model, which has been evolved out of the Hubbard model and ideas based on a resonating valence bond spin liquid. We find that: 1) in underdoped samples, the missing area integrals reveal a second energy scale due to the pseudogap, not present at optimum or overdoping; 2) the real part of the optical self-energy shows a large sharp peak, that emerges with the opening of the pseudogap which exists within the superconducting state and persists in the normal state; and 3) the amount of optical spectral weight which is transferred to the condensate is greatly reduced by the presence of the pseudogap as compared to the Fermi liquid case. These non-BCS features of the superconducting state are in good qualitative agreement with a body of experimental work on different cuprate systems and provide strong evidence from optical conductivity that they are all a manifestation of the pseudogap energy scale.

description: Accretion and ablation, i.e. the addition and removal of mass at the surface, is important in a wide range of physical processes including solidification, growth of biological tissues, environmental processes, and additive manufacturing. The description of accretion requires the addition of new continuum particles to the body, and is therefore challenging for standard continuum formulations for solids that require a reference configuration. Recent work has proposed an Eulerian approach to this problem, enabling the side-stepping of the issue of constructing the reference configuration. However, this raises the complementary challenge of determining the stress response of the solid, which typically requires the deformation gradient that is not immediately available in the Eulerian formulation. To resolve this, the approach introduced the elastic deformation as an additional kinematic descriptor of the added material, and its evolution has been shown to be governed by a transport equation. In this work, the method of characteristics is applied to solve concrete simplified problems motivated by biomechanics and manufacturing. Specifically, (1) for a problem with both ablation and accretion in a fixed domain, and (2) for a problem with a time-varying domain, the closed-form solution is obtained in the Eulerian framework using the method of characteristics without explicit construction of the reference configuration.

description: Image sensors with nondestructive charge readout provide single-photon or single-electron sensitivity, but at the cost of long readout times. We present a smart readout technique to allow the use of these sensors in visible-light and other applications that require faster readout times. The method optimizes the readout noise and time by changing the number of times pixels are read out either statically, by defining an arbitrary number of regions of interest (ROI) in the array, or dynamically, depending on the charge or energy of interest (EOI) in the pixel. This technique is tested in a Skipper CCD showing that it is possible to obtain deep sub-electron noise, and therefore, high resolution of quantized charge, while dynamically changing the readout noise of the sensor. These faster, low noise readout techniques show that the skipper CCD is a competitive technology even where other technologies such as Electron Multiplier Charge Coupled Devices (EMCCD), silicon photo multipliers, etc. are currently used. This technique could allow skipper CCDs to benefit new astronomical instruments, quantum imaging, exoplanet search and study, and quantum metrology.

Abstract:To learn words, humans extract statistical regularities from speech. Multiple species use statistical learning, also to process speech, but the neural underpinnings of speech segmentation in non-humans remain largely unknown. Here we investigated computational and neural markers of speech segmentation in dogs, a phylogenetically distant mammal that efficiently navigates humans’ social and linguistic environment. Using EEG, we compared ERPs for artificial words previously presented in a continuous speech stream with different distributional statistics. Results revealed an early effect (220-470 ms) of transitional probability, and a late component (590-790 ms) modulated by both word frequency and transitional probability. Using fMRI, we searched for brain regions sensitive to statistical regularities in speech. Structured speech elicited lower activity in the basal ganglia, a region involved in sequence learning; and repetition enhancement in the auditory cortex. Speech segmentation in dogs, similarly to humans, involves complex computations, engaging both domain-general and modality-specific brain areas.
Quantum superadditivity in linear optics networks: sending bits via multiple access Gaussian channels

description: We study classical capacity regions of quantum Gaussian multiple access channels (MAC). In classical variants of such channels, whilst some capacity superadditivity-type effects such as the so called {\it water filling effect} may be achieved, a fundamental classical additivity law can still be identified, {\it viz.} adding resources to one sender is never advantageous to other senders in sending their respective information to the receiver. Here, we show that quantum resources allows violation of this law, by providing two illustrative schemes of experimentally feasible Gaussian MACs.
