description: Context. The high-frequency quasi-periodic oscillations (HF QPOs) in neutron star and stellar-mass black hole X-ray binaries may be the result of a resonance between the radial and vertical epicyclic oscillations in strong gravity. Aims. In this paper we investigate the resonant coupling between the epicyclic modes in a torus in a strong gravitational field. Methods. We perform numerical simulations of axisymmetric constant angular momentum tori in the pseudo-Newtonian potential. The epicyclic motion is excited by adding a constant radial velocity to the torus. Results. We verify that slender tori perform epicyclic motions at the frequencies of free particles, but the epicyclic frequencies decrease as the tori grow thicker. More importantly, and in contrast to previous numerical studies, we do not find a coupling between the radial and vertical epicyclic motions. The appearance of other modes than the radial epicyclic motion in our simulations is rather due to small numerical deviations from exact equilibrium in the initial state of our torus. Conclusions. We find that there is no pressure coupling between the two axisymmetric epicyclic modes as long as the torus is symmetric with respect to the equatorial plane. However we also find that there are other modes in the disc that may be more attractive for explaining the HF QPOs.

description: Cranioplasty is the surgical process where a skull defect resulting from previous surgery or injury is repaired using an implant that restores the original protective and aesthetic function of the skull. Implications range from decompressive craniectomies to performing brain surgery. Although the patient’s autologous bone is routinely used as the implant material, it may not always be possible due to infection, fracture or bone tumour. Using autologous bone also poses significant risk of requiring a secondary surgery due to bone resorption [1]. Artificial patient-specific implants (PSI) created using computed-assisted design reduce overall patient risks as well as operating time [2]. Developing automatic skull reconstruction methods will increase the availability of PSIs as well as enable their design and subsequent manufacturing directly inside the operating room. Prior to the first AutoImplant Challenge (AutoImplant 2020, held in conjunction with MICCAI 2020 https://autoimplant.grand-challenge.org/), automatic design of cranial implant has been a under-researched area, due to a lack of proper formulation of the problem from a technical perspective. In AutoImplant 2020, we formulated cranial implant design as a volumetric shape completion and 3D shape learning task. Based on the
 formulation, various data-driven approaches, such as deep learning and statistical shape model can be employed in solving the problem. AutoImplant 2021 is a substantial extension to the AutoImplant 2020 challenge, where only synthetic defects were used for training and evaluation. In AutoImplant 2021, real clinical defective skulls from craniotomy and skulls with traumatic defects will be used in the evaluation phase, each serving as a separate track (task). The original AutoImplant 2020 task will serve as a third track of AutoImplant 2021. Using real cases for evaluation will guarantee the clinical usability of the winning algorithms.

description: MICCAI endorsed event A distinct feature of malignant tumors compared to normal tissue or benign tumors is the invasiveness of transformed cells. Malignant tumor cells can invade vessels, nerves, stroma (through the basement membrane), lymph nodes, and other distant organs. Metastasis to lymph nodes and distant organs is a unique feature of malignant tumors, and it affects patient survival. Nerves are normal structures which connect the brain to peripheral organs, and transmit electrical signals which are responsible for voluntary and non-voluntary motor control and sensory perception. Nerves and blood vessels are the main pathways through which malignant cells can move from a primary site to other organs. Perineural invasion by malignant tumor cells has been reported as an independent indicator of poor prognosis in cancers. The College of American Pathologists recommended the inclusion of perineural invasion in pathology reports for resected specimens of malignant tumors. Detection of perineural invasion in small nerves on glass slides is a labor-intensive task. Histologically, perineural invasion is composed of nerve and tumor cells attached to the nerve, and the nerve may be completely enclosed within the tumor mass. The morphology of nerves is the same in all organs, but tumor cells have various forms according to the histologic type and organs they are present in, thus modelling cancer in every organ is difficult. In the case of similar histology among the different cancers, it is challenging to determine whether an algorithm can be made for common histologic elements even if the background organs are different. This challenge aims to promote the development of a common algorithm for automatic detection of perineural invasion in resected specimens of multi-organ cancers. This challenge will have a technical impact in the following fields: detection of composite target (nerve and tumor) and common modeling for target images in multiple backgrounds. This challenge will provide a good opportunity to overcome the limitations of current diseaseorgan- specific modeling and develop a technological approach to the universality of histology in multiple organs.
Self-identity, class, and social stratification in the movie Parasite
Creators: name: Chan, Yat
Publisher: name: No Publisher Supplied
Year: 2021

description: The movie Parasite displays a story of three families moving between classes. The movement and lens of the characters show how the living environment represents their social position and how classism and social stratification is implemented within their society. To confirm and prove that classism does exist across all strata of society, this thesis analyzes the storyline and dialogue of Parasite, the production design, cinematography, sounds, original score, visual effects, and film editing. This analysis is guided by the following questions:How does topography in the movie Parasite reveal classism in the South Korean society?How are these landscape representations of social hierarchies generalized in contemporary societies around the world? These questions are answered through a detailed movie analysis of Parasite. By viewing the movie and researching the meaning behind the characters’ travel between the three houses where they live, it displays the topographical evidence of classism in South Korea. From the neighborhood, streets, entry, house, and views outside the house, to the cleanliness and smells inside the house, these character movements through the landscape creates an excellent study of social stratification. Since production design is different than architecture, the houses in Parasite consist of objects and scenery that are symbolic of class in South Korea and beyond. Moreover, these cinematic landscapes serve as focal points that make the audience reflect back on their living environment and the way it has been, and continues to be, shaped by years of social stratification that operates unconsciously in people, which, for the most part, they fail to notice until it is pointed out.

description: The completeness of the Gaia catalogues heavily depends on the status of that space telescope through time. Stars are only published with each of the astrometric, photometric and spectroscopic data products if they are detected a minimum number of times. If there is a gap in scientific operations, a drop in the detection efficiency or Gaia deviates from the commanded scanning law, then stars will miss out on potential detections and thus be less likely to make it into the Gaia catalogues. We lay the groundwork to retrospectively ascertain the status of Gaia throughout the mission from the tens of individual measurements of the billions of stars, by developing novel methodologies to infer both the orientation and angular velocity of Gaia through time and gaps and efficiency drops in the detections. We have applied these methodologies to the Gaia DR2 variable star epoch photometry -- which are the only publicly available Gaia time-series at the present time -- and make the results publicly available. We accompany these results with a new Python package scanninglaw (https://github.com/gaiaverse/scanninglaw) that you can use to easily predict Gaia observation times and detection probabilities for arbitrary locations on the sky.

The politics of possession: Louis Shotridge and the Tlingit collections of the University of Pennsylvania Museum
Creators: name: Milburn, Maureen Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: For twenty years, from 1912-1932, Louis Shotridge (Stoowukáa V), a Tlingit nobleman of the Chilkat Kaagwaantaan clan, was employed by the University of Pennsylvania Museum in Philadelphia as field collector, curator, and exhibit preparator. In this position, Shotridge was given full responsibility for the selection and acquisition of a collection of Northwest Coast objects. During this time, Shotridge grew to perceive his collections and their attendant documentation as a testament to Tlingit social structures and ancestral histories as well as the moral and ethical values of the Tlingit clans and the legitimating identities of clan leaders. While trained by Franz Boas in ethnographic method, Shotridge remained grounded in existing Tlingit social systems, combined with then-current Native American idealism and political objectives. Thus while he traveled through Tlingit territory collecting objects and recording their clan histories, he was also active in the Alaska Native Brotherhood. In his lifetime, Shotridge was respected both by Tlingit peoples and by the anthropological community. Yet more recently, anthropological and popular writers have vilified Shotridge as a traitor, making him emblematic of a continuing colonial discourse constructed to preserve boundaries which recognize only the "pure products" of the "primitive" Native American. Instead of continuing such dichotomous constructions, this thesis more carefully evaluates the circumstances under which objects were acquired and recontextualized within a Western institutional museum setting in the early part of this century. Rather than glossing over questions of hybridity, this thesis is particularly concerned with the ways certain individuals penetrate societal boundaries, under what circumstances, to what purposes and within what contexts such associations are initiated, sanctioned, legitimated or contested. By discussing and contextualizing Shotridge's life and ethnographic activity, this thesis argues for a broader understanding of Native American political circumstances, values, and struggles within a framework of post-colonial relations. Consideration of these various perspectives provides a clearer view of historical representation and ownership of objects, issues which continue to inform contemporary concerns regarding possession and the meaning of objects within both anthropology museum and tribal contexts.

description: It is now a firmly established fact that all family lepton numbers are violated in Nature. In this paper we discuss the implications of this observation for future searches for rare tau decays in the supersymmetric see-saw model. Using the two loop renormalization group evolution of the soft terms and the Yukawa couplings we show that there exists a lower bound on the rate of the rare process mu --> e gamma of the form BR(mu --> e gamma) > C BR(tau --> mu gamma) BR(tau --> e gamma), where C is a constant that depends on supersymmetric parameters. Our only assumption is the absence of cancellations among the high-energy see-saw parameters. We also discuss the implications of this bound for future searches for rare tau decays. In particular, for large regions of the mSUGRA parameter space, we show that present B-factories could discover either tau --> mu gamma or tau --> e gamma, but not both.

description: The control of large-scale quantum information processors based on arrays of trapped ions requires a means to route and focus multiple laser beams to each of many trapping sites in parallel. Here, we combine arrays of fibres, 3D laser-written waveguides and diffractive microlenses to demonstrate the principle of a micro-optic interconnect suited to this task. The module is intended for use with an ion microtrap of 3D electrode geometry. It guides ten independent laser beams with unique trajectories to illuminate a pair of spatially separated target points. Three blue and two infrared beams converge to overlap precisely at each desired position. Typical relative crosstalk intensities in the blue are $3.6 \times 10^{-3}$ and the average insertion loss across all channels is $8~$dB. The module occupies $\sim 10^4$ times less volume than a conventional bulk-optic equivalent and is suited to different ion species.

description: By measuring the Hall coefficient R_H up to 1000 K in La_2CuO_4, Pr_{1.3}La_{0.7}CuO_4, and La_{2-x}Sr_xCuO_4 (LSCO), we found that the temperature (T) dependence of R_H in LSCO for x = 0 - 0.05 at high temperature undoubtedly signifies a gap over which the charge carriers are thermally activated, which in turn indicates that in lightly-doped cuprates strong charge fluctuations are present at high temperature and the carrier number is not a constant. At higher doping (x = 0.08 - 0.21), the high-temperature R_H(T) behavior is found to be qualitatively the same, albeit with a weakened temperature dependence, and we attempt to understand its behavior in terms of a phenomenological two-carrier model where the thermal activation is considered for one of the two species. Despite the crude nature of the model, our analysis gives a reasonable account of R_H both at high temperature and at 0 K for a wide range of doping, suggesting that charge fluctuations over a gap remain important at high temperature in LSCO deep into the superconducting doping regime. Moreover, our model gives a perspective to understand the seemingly contradicting high-temperature behavior of R_H and the in-plane resistivity near optimum doping in a consistent manner. Finally, we discuss possible implications of our results on such issues as the scattering-time separation and the large pseudogap.

description: Sapotaceae is a very representative family that consists of large, long-lived, animal-dispersed, shade-tolerant trees typical of mature forests, and several timber species. Previously included in Pouteria, the genus Peteniodendron is distributed in South America and comprises four species commonly known as abiurana: P. durlandii (Pdu), P. jariense (Pja), P. pallens (Ppa), and P. virescens (Pvi). In central Amazonia, the species coexist in terra-firme forests as canopy trees with many morphological resemblances in the early stages. We tested if fruit and seed traits were effective in distinguishing the species. Fruits were collected in two protected areas north of Manaus: Ducke Reserve and BDFFP permanent plots. We weighted (precision of 0.001 g) and measured (precision of 0.01 mm) the length, thickness, and width of at least 30 fruits and 30 seeds from each tree per species whenever possible. We analyzed the trait data using a custom R script. Fruit—Pdu: ellipsoid, 2.7–10.5 g and 25.1–36.5×17.6–22.2×16.8–20.7 mm; Pja: globose, 4.6–8.9 g and 28.9–32.8×17.3–24.6×17.2–21.5 mm; Ppa: globose, 4.2–13.6 g and 24–38.5×19.1–29.1×17.9–28.2 mm; Pvi: ovoid, 13.3–34.9 g and 38.9–53.4×26–38.6×25.6–37.4 mm. Seed—Pdu: ovoid, 1.2–1.8 g and 21.1–26.5×9.5–11.9×8.6–10.2 mm; Pja: ovoid to ellipsoid, 1–1.7 g and 19.7–22.7×8.7–11.1×8.1–9.8 mm; Ppa: ovoid, 1–2.1 g and 19.9–25.8×10.1–12.3×9.1–10.7 mm; Pvi: ellipsoid, 1.1–3.3 g and 20.8–29.2×9.8–16.7×7–13.7 mm. Fruit weight, thickness, and width were more effective in separating species than seed traits. Pvi showed the least overlap in fruit traits compared to congeners. More significant overlap was observed between Pdu and Pja, reflecting their close evolutionary relationship. It is the first time that fruit and seed of Peteniodendron species have been compared. Fruit biometry has proven to be an effective tool for species identification and represents genetic variability, important for forest restoration projects with native trees.
A model of rotating convection in stellar and planetary interiors: II -- gravito-inertial wave generation

description: Gravito-inertial waves are excited at the interface of convective and radiative regions and by the Reynolds stresses in the bulk of the convection zones of rotating stars and planets. Such waves have notable asteroseismic signatures in the frequency spectra of rotating stars, particularly among rapidly rotating early-type stars, which provides a means of probing their internal structure and dynamics. They can also transport angular momentum, chemical species, and energy from the excitation region to where they dissipate in radiative regions. To estimate the excitation and convective parameter dependence of the amplitude of those waves, a monomodal model for stellar and planetary convection as described in Paper I is employed, which provides the magnitude of the rms convective velocity as a function of rotation rate. With this convection model, two channels for wave driving are considered: excitation at a boundary between convectively stable and unstable regions and excitation due to Reynolds-stresses. Parameter regimes are found where the sub-inertial waves may carry a significant energy flux, depending upon the convective Rossby number, the interface stiffness, and the wave frequency. The super-inertial waves can also be enhanced, but only for convective Rossby numbers near unity. Interfacially excited waves have a peak energy flux near the lower cutoff frequency when the convective Rossby number of the flows that excite them are below a critical Rossby number that depends upon the stiffness of the interface, whereas that flux decreases when the convective Rossby number is larger than this critical Rossby number.

We also confirm that the appearance of the S-wave bound state is accompanied by an abrupt sign change of the S-wave scattering length even in finite volume through numerical simulations. This distinctive behavior may help us to discriminate the loosely bound state from the lowest energy level of the scattering state in finite volume simulations.

description: When the first cases of COVID-19 infection started to be detected the profound difference between patients in terms of severity of disease quickly became evident. A vast majority of patients remained asymptomatic and eventually healed while some, despite lacking initial symptom, eventually worsen and a few fell ill quite rapidly. While facing a new disease, COVID-19 pneumonia was approached based on medical knowledge translated from the most similar illness but, a year later since the beginning of the outbreak in Northern Italy, knowledge has evolved. This text has the intent to offer a comprehensive view of COVID-19 pneumonia and its treatment options as a continuum of the same but complex disease, from the early to the late phase.
title: A new look at an old friend: A geometric morphometric approach to examining morphological diversity and investigating human-canid relationships in New World prehistory
Creators: name: Ameen, CE
Publisher: name: University of Liverpool Repository
Year: 2018

description: Identifying domesticates in the archaeological record is one of the major goals of zooarchaeology, and as the first known domesticate, significant attention has been given to investigating dogs in archaeological research. Less attention has been paid to the morphological variation exhibited by prehistoric dogs after their do- mestication. Since the New World lacks the large scale husbandry of economically important livestock animals, dogs are arguably the most significant domesticate in American prehistory, and are the only domesticate shared by almost all cultures. Advances in geometric morphometric (GMM) techniques have improved our abil- ity to investigate the subtle biological variations between wild and domestic ani- mals. This thesis uses advanced GMM techniques to identify domesticates from prehistoric archaeological assemblages. These methods are then used to examine the morphological variability of dogs in New World prehistory. This post-domestic variation might inform on the diverse and fluid cultural relationships between hu- mans and the domestic dog. The results of this thesis are presented as a series of case studies which first offer a comprehensive investigation of the underlying morphological variability of the dogs’ wild ancestor, the grey wolf. Then, specimens from over 80 prehistoric archaeological sites across the New World are first identified as either wild or domestic, and then examined for temporal, geographic and cultural trends on both continents. Results indicate that prehistoric dogs exhibit significant shape and size differences in association with temporal and geographic contexts, which are correlated with changes in dog husbandry practices through- out prehistory. Morphological data combined with other complimentary scientific approaches (namely stable isotope and DNA analysis), show significant implications for understanding the human past using dogs as a proxy for human movements and migrations. A synthesis of these interrelated case studies provides a framework for future investigations into the individual life-ways and life-histories of prehistoric dogs as well as methods for interpreting their position in human society using a suite of interrelated analytical techniques.

An alternative formulation arises by introducing the enhanced Teichmueller space of S: We prove that any two points of the latter are related by a unique right earthquake. The proof rests on the geometry of ``multi-black holes'', which are 3-dimensional anti-de Sitter manifolds, topologically the product of a surface with boundary by an interval.

description: Recent exoplanet statistics indicate that photo-evaporation has a great impact on the mass and bulk composition of close-in low-mass planets. While there are many studies addressing photo-evaporation of hydrogen-rich or water-rich atmospheres, no detailed investigation regarding rocky vapor atmospheres (or mineral atmospheres) has been conducted. Here, we develop a new 1-D hydrodynamic model of the UV-irradiated mineral atmosphere composed of Na, Mg, O, Si, their ions and electrons, includin molecular diffusion, thermal conduction, photo-/thermo-chemistry, X--ray and UV heating, and radiative line cooling (i.e., the effects of the optical thickness and non-LTE). The focus of this paper is on describing our methodology but presents some new findings. Our hydrodynamic simulations demonstrate that almost all of the incident X-ray and UV energy from the host-star is converted into and lost by the radiative emission of the coolant gas species such as Na, Mg, Mg$^+$, Si$^{2+}$, Na$^{3+}$ and Si$^{3+}$. For an Earth-size planet orbiting 0.02~AU around a young solar-type star, we find that the X-ray and UV heating efficiency is as small as $1 \times 10^{-3}$, which corresponds to 0.3~$\Mearth$/Gyr of the mass loss rate simply integrated over all the directions. Because of such efficient cooling, the photo-evaporation of the mineral atmosphere on hot rocky exoplanets with masses of $1\Mearth$ is not massive enough to exert a great influence on the planetary mass and bulk composition. This suggests that close-in high-density exoplanets with sizes larger than the Earth radius survive in the high-UV environments.

description: The basic results of a new theory of regular functions of a quaternionic variable have been recently stated, following an idea of Cullen. In this paper we prove the minimum modulus principle and the open mapping theorem for regular functions. The proofs involve some peculiar geometric properties of such functions which are of independent interest.

Process POVM: A mathematical framework for the description of process tomography experiments

description: In this paper we shall introduce the mathematical framework for the description of measurements of quantum processes. Using this framework the process estimation problems can be treated in the similar way as the state estimation problems, only replacing the concept of positive operator valued measure (POVM) by the concept of process POVM (PPOVM). In particular, we will show that any measurement of qudit channels can be described by a collection of effects (positive operators) defined on two-qudit system. However, the effects forming a PPOVM are not normalized in the usual sense. We will demonstrate the usage of this formalism in discrimination problems by showing that perfect channel discrimination is equivalent to a specific unambiguous state discrimination.

Community-based sustainability and the construction of difference on Galiano Island, British Columbia
Creators: name: Rowson, Juliet Mary
Publisher: name: University of British Columbia

description: The 'community-based sustainability ideal' is a North American brand of sustainability which envisions place-based communities as the ideal forum for the achievement of sustainability. There are three linchpins to the ideal: place, community, and sustainability. According to the ideal, community is place-based, and is the site in which the goals of ecological integrity, economic well-being and social cohesion can best be advanced, rendering it the ideal locus for sustainability. As such, the three linchpins are seamlessly bound together as a 'common sense' package. I argue, however, that these linchpins are thus-far ill-conceived because they romanticize local social relations, systematically erasing any sense that there may be difference and conflict generated in place-based communities attempting sustainability. My position is that any desirable and attainable vision of community-based sustainability must be grounded in the discursive realities of the present. Given that difference and conflict are unlikely to disappear from place-based communities in the foreseeable future, these issues must therefore be explicitly incorporated in any vision of community-based sustainability. To this end, I deconstruct the representations of place, commumty and sustainability embedded in the 'community-based sustainability ideal' and suggest an alternative, less problematic way in which community-based sustainability can be imagined. My arguments are filtered through, and shaped by, a case study of Galiano Island, British Columbia, which constitutes a place-based community attempting sustainability. The thesis argues that the 'community-based sustainability ideal' should be reworked such that place is de-essentialized, so that it is possible to recognize multiple, conflicting representations of place. Similarly, the assumption that commumty members are united through a shared unity of purpose needs to be challenged so that difference and conflict are recognized as integral aspects of community. Finally, sustainability advocates need to acknowledge that there is not one, but multiple ways in which sustainability can be interpreted in place-based communities. From here, advocates of community-based sustainability are in a position to suggest how differences can be articulated and positions negotiated, such that workable, desirable visions of sustainability can be pursued.

description: We present rest-frame optical spectroscopic observations of 24 Hot Dust-Obscured Galaxies (Hot DOGs) at redshifts 1.7-4.6 with KECK/NIRES. Our targets are selected based on their extreme red colors to be the highest luminosity sources from the WISE infrared survey. In 20 sources with well-detected emission we fit the key [O III], H$β$, H$α$, [N II], and [S II] diagnostic lines to constrain physical conditions. Of the 17 targets with a clear detection of the [O III]$\rm λ$5007A emission line, 15 display broad blueshifted and asymmetric line profiles, with widths ranging from 1000 to 8000 $\rm km\ s^{-1}$ and blueshifts up to 3000 $\rm km\ s^{-1}$. These kinematics provide strong evidence for the presence of massive ionized outflows of up to $8000\ \rm M_\odot\ yr^{-1}$, with a median of $150\ \rm M_\odot\ yr^{-1}$. As many as eight sources show optical emission line ratios consistent with vigorous star formation. Balmer line star-formation rates, uncorrected for reddening, range from 30--1300 $\rm M_\odot\ yr^{-1}$, with a median of $50\ \rm M_\odot\ yr^{-1}$. Estimates of the SFR from SED fitting of mid and far-infrared photometry suggest significantly higher values. We estimate the central black hole masses to be of order $10^{8-10}\rm\ M_\odot$, assuming the present-day $\rm M_{BH}-σ_*$ relation. The bolometric luminosities and the estimated masses of the central black holes of these galaxies suggest that many of the AGN-dominated Hot DOGs are accreting at or above their Eddington limit. The combination of ongoing star formation, massive outflows, and high Eddington ratios suggest Hot DOGs are a transitional phase in galaxy evolution.

description: We present diffraction-limited (FWHM ~ 0.3arcsec) Gemini/T-ReCS mid-infrared (MIR: N-band or narrow-band at 8.7micron) imaging of four Luminous Infrared Galaxies (LIRGs) drawn from a representative local sample. The MIR emission in the central few kpc is strikingly similar to that traced by Pa-alpha, and generally consists of bright nuclear emission and several compact circumnuclear and/or extranuclear HII regions. The central MIR emission is dominated by these powerful HII regions, consistent with the majority of AGN in this local sample of LIRGs contributing a minor part of the MIR emission. The luminous circumnuclear HII regions detected in LIRGs follow the extrapolation of the 8micron vs. Pa-alpha relation found for M51 HII knots. The integrated central 3-7kpc of galaxies, however, present elevated 8micron/Pa-alpha ratios with respect to individual HII regions, similar to the integrated values for star-forming galaxies. Our results show that the diffuse 8micron emission, not directly related to the ionizing stellar population, can be as luminous as that from the resolved HII regions. Therefore, calibrations of the star formation rate for distant galaxies should be based on the integrated 8micron emission of nearby galaxies, not that of the HII regions alone.

description: In cell-free massive multiple-input multiple-output (MIMO) the fluctuations of the channel gain from the access points to a user are large due to the distributed topology of the system. Because of these fluctuations, data decoding schemes that treat the channel as deterministic perform inefficiently. A way to reduce the channel fluctuations is to design a precoding scheme that equalizes the effective channel gain seen by the users. Conjugate beamforming (CB) poorly contributes to harden the effective channel at the users. In this work, we propose a variant of CB dubbed enhanced normalized CB (ECB), in that the precoding vector consists of the conjugate of the channel estimate normalized by its squared norm. For this scheme, we derive an exact closed-form expression for an achievable downlink spectral efficiency (SE), accounting for channel estimation errors, pilot reuse and user's lack of channel state information (CSI), assuming independent Rayleigh fading channels. We also devise an optimal max-min fairness power allocation based only on large-scale fading quantities. ECB greatly boosts the channel hardening enabling the users to reliably decode data relying only on statistical CSI. As the provided effective channel is nearly deterministic, acquiring CSI at the users does not yield a significant gain.
