Exploring the relationship between perceived neglect and violence and problematic alcohol use in adolescents, undergraduate students, and clinical patients
Creators: name: Edalati Esmaeilzadeh, Hanie
Publisher: name: University of British Columbia
Year: 2015

description: The present dissertation aimed to understand how perceived maltreatment including neglect and violence places individuals at risk for problematic alcohol use through the development of a framework of vulnerability. We tested the role of dual process pathways including system 1 (alcohol automatic memory associations) and system 2 (future orientation, and alcohol outcome expectancies) processes, risky personality traits, and current perceived stress as the underlying structure between perceived maltreatment and alcohol use and problematic drinking in three groups of participants : adolescents (n = 145), undergraduate students (n = 510), and clinical patients under treatment for substance use disorders (n=100). In all three groups, perceived maltreatment was associated with higher current perceived stress, development of risky personality traits, and lower future orientation and positive or coping alcohol expectancies. Only maltreated undergraduate students indicated more alcohol-related coping memory associations. In adolescents, more alcohol feeling good expectancy, higher sensation seeking and impulsivity mediated the relationship between violence and recency of alcohol use. In undergraduate students, more alcohol-related coping memory associations, lower future orientation, and higher sensation seeking mediated the relationship between higher frequency of alcohol use and problematic drinking. Higher impulsivity also mediated the relationship between violence and problematic alcohol use in this group. The best dual processes pathway that connected violence to problematic alcohol use was via alcohol coping association and future orientation in undergraduate students, in that those with higher levels of violence showed impaired future orientation, and were more likely to shape alcohol-related coping memory associations, and that this cognitive pathway resulted in higher rates of problematic alcohol use. In general, neglected males and females exposed to violence indicated a pattern similar to internalizing problems. In contrast, a pattern of externalizing problems were increased in neglected females and males exposed to violence by adding sex to the analysis. Our findings suggest that intervention programs for problematic drinking should consider screening for experiences of violence. Maltreated individuals with alcohol problems would benefit from interventions that improve rational thinking and behavioural inhibition, and learning how to cope effectively with the stress and the experience of maltreatment.

description: The Large Magellanic Cloud (LMC) contains the nearest large extragalactic population of planetary nebulae (PNe). A shallow viewing angle and low interstellar reddening towards the LMC potentially means a larger, more complete flux-limited population can be assembled than for any other galaxy. These advantages appear to be reflected by the small gap between the catalogued ($\sim$700 PNe) and estimated ($1000\pm250$ PNe) population size. With more detailed multi-wavelength studies the catalogued number of LMC PNe may fall, potentially widening this gap. We demonstrate here that the gap can be further bridged with improved optical and near-infrared imaging surveys. We present three [O III]-selected PNe discovered from ESO WFI observations of the 30 Doradus region and one serendipitous discovery from near-infrared Vista Magellanic Cloud (VMC) survey observations. The WFI PNe have resolved [O III] and H$α$ nebulae that verify their PN nature and their [O III] fluxes place them 6--7 mag ($m_{5007}=20$--21 mag) fainter than the bright-end of the planetary nebula luminosity function (PNLF). Their faintness, small angular size and surrounding complex emission-line background explains why previous H$α$ surveys of the region did not select them. We estimate there may be as many as 50--75 similar PNe awaiting discovery in the central $5\times5$ degrees of the LMC. The VMC survey routinely detects PNe as red resolved nebulae that may allow some of this expected population to be recovered without traditional narrow-band imaging surveys. We demonstrate this potential with the first new VMC-selected PN which has a rare Wolf-Rayet [WC9]--[WC11] central star.

description: An original dispersion relation between the stationary coherent nonlinear optical responses by current and polarisation is obtained. The dispersion relation provides a new complimentary tool that can be employed to study light-induced charge transport models and facilitate experimental data analysis. It is shown that the origin of the coherent current and the dc-polarisation induced in a noncentrosymmetric crystal under illumination is related to the theory of the Berry phase and can be represented in terms of the renormalised geometric potentials. This renormalisation originates from the extra phase difference acquired by a carrier in the light field on the quantum transition between the electronic bands. The gauge invariance of the corresponding expressions for the current and the polarisation is demonstrated.

description: The Interstellar Boundary Explorer (IBEX) mission is exploring the frontiers of the heliosphere where energetic neutral atoms (ENAs) are formed from charge exchange between interstellar neutral hydrogen atoms and solar wind ions and pickup ions. The geography of this frontier is dominated by an unexpected nearly complete arc of ENA emission, now known as the IBEX 'Ribbon'. While there is no consensus agreement on the Ribbon formation mechanism, it seems certain this feature is seen for sightlines that are perpendicular to the interstellar magnetic field as it drapes over the heliosphere. At the lowest energies, IBEX also measures the flow of interstellar H, He, and O atoms through the inner heliosphere. The asymmetric oxygen profile suggests that a secondary flow of oxygen is present, such as would be expected if some fraction of oxygen is lost through charge exchange in the heliosheath regions. The detailed spectra characterized by the ENAs provide time-tagged samples of the energy distributions of the underlying ion distributions, and provide a wealth of information about the outer heliosphere regions, and beyond.

description: In this paper we apply in a systematic way a previously developed integration algorithm of the relevant Lax equation to the construction of spherical symmetric, asymptotically flat black hole solutions of N=2 supergravities with symmetric Special Geometry. Our main goal is the classification of these black-holes according to the H*-orbits in which the space of possible Lax operators decomposes, H* being the isotropy group of scalar manifold originating from time-like dimensional reduction of supergravity from D=4 to D=3 dimensions. The main result of our investigation is the construction of three universal tensors, extracted from quadratic and quartic powers of the Lax operator, that are capable of classifying both regular and nilpotent H* orbits of Lax operators. Our tensor based classification is compared, in the case of the simple one-field model S^3, to the algebraic classification of nilpotent orbits and it is shown to provide a simple and practical discriminating method. We present a detailed analysis of the S^3 model and its black hole solutions, discussing the Liouville integrability of the corresponding dynamical system. By means of the Kostant-representation of a generic Lie algebra element, we were able to develop an algorithm which produces the necessary number of hamiltonians in involution required by Liouville integrability of generic orbits. The degenerate orbits correspond to extremal black-holes and are nilpotent. We analyze these orbits in some detail working out different representatives thereof and showing that the relation between H* orbits and critical points of the geodesic potential is not one-to-one. Finally we present the conjecture that our newly identified tensor classifiers are universal and able to label all regular and nilpotent orbits in all homogeneous symmetric Special Geometries.

description: The Wigner crystal of composite fermions is a strongly correlated state of complex emergent particles, and therefore its unambiguous detection would be of significant importance. Recent observation of optical resonances in the vicinity of filling factor ν = 1/3 has been interpreted as evidence for a pinned Wigner crystal of composite fermions [Zhu et al., Phys. Rev. Lett. 105, 126803 (2010)]. We evaluate in a microscopic theory the shear modulus and the magnetophonon and magnetoplasmon dispersions of the composite fermion Wigner crystal in the vicinity of filling factors 1/3, 2/5, and 3/7. We determine the region of stability of the crystal phase, and also relate the frequency of its pinning mode to that of the corresponding electron crystal near integer fillings. These results are in good semiquantitative agreement with experiment, and therefore support the identification of the optical resonance as the pinning mode of the composite fermions Wigner crystal. Our calculations also bring out certain puzzling features, such as a relatively small melting temperature for the composite fermion Wigner crystal, and also suggest a higher asymmetry between Wigner crystals of composite fermion particles and holes than that observed experimentally.

Publisher: name: University of British Columbia
Year: 2015

description: Microfluidics technology shows a wide variety of applications in multiple research areas. Up to now, most of the microfluidic devices are fabricated in the cleanroom, using the highly sophisticated instruments. With the desire to make the microfluidic systems more accessible to chemical or biological researchers, a series of low-cost fabrication technologies for polymer-based microfluidic systems will be introduced in this research. With the help of these proposed low-cost and cleanroom-free fabrication methods for polymer-based microfluidic devices, users could easily fabricate their own microfluidic devices based on their usage. These proposed low-cost fabrication technologies covered all three steps of the microfluidic systems fabrication processes, which are microchannel fabrication, microchannel sealing (bonding) and integration technologies. For microchannel fabrication, different low-cost methods such as laser ablation and deep-UV patterning will be introduced in this research. For microchannel sealing method, the thermocompression bonding technology will be investigated in detail. For integration technologies in microfluidic systems, various kinds of low-cost integration technologies for microlenses, metal electrodes and wafer dicing will be introduced. In this research, the introduced low-cost fabrication technologies for microfluidic systems are based on different polymer materials such as poly(methyl methacrylate) (PMMA), polystyrene (PS) and polydimethylsiloxane (PDMS). The fabrication, bonding and integration methods introduced in this research can be widely adapted to different polymer materials. This research offers a flexible choice of polymer materials and fabrication technologies to maximize the utility for researchers, and could be beneficial to lower the access of microfluidics technologies in chemical and biological fields.

description: We report on the lattice evolution of BiFeO3 as function of temperature using far infrared emissivity, reflectivity, and X-ray absorption local structure. A power law fit to the lowest frequency soft phonon in the magnetic ordered phase yields an exponent β=0.25 as for a tricritical point. At about 200 K below TN~640 K it ceases softening as consequence of BiFeO3 metastability. We identified this temperature as corresponding to a crossover transition to an order-disorder regime. Above ~700 K strong band overlapping, merging, and smearing of modes are consequence of thermal fluctuations and chemical disorder. Vibrational modes show band splits in the ferroelectric phase as emerging from triple degenerated species as from a paraelectric cubic phase above TC~1090 K. Temperature dependent X-ray absorption near edge structure (XANES) at the Fe K-edge shows that lower temperature Fe3+ turns into Fe2+. While this matches the FeO wüstite XANES profile, the Bi LIII-edge downshift suggests a high temperature very complex bond configuration at the distorted A perovskite site. Overall, our local structural measurements reveal high temperature defect-induced irreversible lattice changes, below, and above the ferroelectric transition, in an environment lacking of long-range coherence. We did not find an insulator to metal transition prior to melting.

description: This article provides an overview of commemorations of the centenary of the First World War in Turkey. I first focus on the official commemorations of the battles of Sarıkamış, Gallipoli, and Kut, which were organized around isolated “victories” and “martyrdom” – consciously avoiding a complete historiography of the war. Moreover, in line with the current government’s Islamist tendencies, official centenary events aimed to overwrite secularist historiography by reducing the visibility of Mustafa Kemal and by highlighting the role of Muslim faith and solidarity under “Turkish leadership.” Official commemorations also aimed to suppress and silence the centenary of the Armenian Genocide. In the second part of the article, I discuss a few academic and artistic centenary events, that were organized by civil initiatives in 2014 and 2015 and sought to remedy the silence on the genocide, along with providing anti-militarist commemoration of the centenary.

description: In the modern era, new forms of mourning and meaning-making for fallen soldiers emerged. The human losses of the First World War were largely mourned, honoured and remembered within historically-established traditions, supplemented by only a few new forms. This “political cult of the dead” focussed equally on the “private” and the “political” body of the fallen soldier, both allowing relatives to mourn and providing a political justification. The First World War acted as a catalyst for the global spread of the political cult of the dead. The concrete formation of the commemoration of the dead was closely linked to nation- and state-building, while factors such as cultural and religious influences, conventional systems of government and colonial traditions explain its various manifestations.

Even a neutral country such as Sweden couldn’t completely escape this fact, finding itself no better off economically as a result of the war. Economic growth was severely halted towards the end of the war when international trade was cut off and recovery was put to a quick stop with a post-war recession in 1920-1921. By 1921, Sweden was no richer than it had been in 1913. The effects were felt by the population as well, with increasing prices, decreasing real wages, food and housing shortages, and rationing.

These new games sought either to tell new stories of war and conflict during the time period or to utilise the fact that it was a little-explored war in games to bring their audience something new. The success of these games was mixed; they did achieve notable results in portraying elements of the conflict not often understood by western, particularly British, audiences. However, they also reproduced many of the shortcomings of traditional media regarding imperial contribution and the causes of the war.

description: We present first-principles supercell calculations on BaTi0.74Zr0.26O3, a prototype material for relaxors with a homovalent substitution. From a statistical analysis of relaxed structures, we give evidence for four types of Ti-atom polar displacements: along the < 1 1 1 >, < 1 1 0 >, or < 1 0 0 > directions of the cubic unit cell, or almost cancelled. The type of a Ti displacement is entirely determined by the Ti/Zr distribution in the adjacent unit cells. The underlying mechanism involves local strain effects that ensue from the difference in size between the Ti4+ and Zr4+ cations. These results shed light on the structural mechanisms that lead to disordered Ti displacements in BaTi(1-x)Zr(x)O3 relaxors, and probably in other BaTiO3-based relaxors with homovalent substitution.

MPC- based mobile robots motion planning and control in uncertain dynamic environment
Creators: name: Farrokhsiar, Morteza
Publisher: name: University of British Columbia
Year: 2015

description: The main focus of this thesis is on the motion planning and control of mobile robots in dynamic unstructured environments in which the primary challenge is to formulate and deal with uncertainty. This thesis contributes to the motion planning problem in three distinct yet related aspects that can together present a model predictive approach to enhance autonomy of mobile robots in dynamic unknown environments. The first contribution of this thesis is to introduce a robust yet probing control algorithm. The proposed algorithm is based on the output-feedback tube-based model predictive control (MPC). The performance of the algorithm has been enhanced using the partially-closed loop strategy. The tube-based approach requires uncertainties to be modeled in the set-theoretic framework, whereas the partially closed-loop strategy is modeled in the probabilistic framework. A key component of the algorithm is related to proposing the relationship between these two different paradigms. The proposed framework utilizes the uncertainty fusion in the probabilistic framework and collision avoidance in the set-theoretic framework. The efficiency of the proposed algorithm is verified using thorough numerical simulations and experiments. The second contribution of this thesis is in regards with linearization of stochastic nonlinear systems. A statistical linearization method, unscented transform, is proposed to replace the analytical linearization method in MPC. The advantage and disadvantage of such replacement has been examined through extensive numerical simulations. The numerical simulation indicates that statistical linearization has two important advantages. First, the proposed approach is derivative free that is it can be applied to complex systems for which no analytical model exists. Second, it is more accurate so that it enhances performance of the planning algorithm. However, the tradeoff is that the analytical linearization is computationally less expensive. The third contribution of this thesis is related to the formulation of the robust tube-based MPC scheme for incremental smoothing and mapping known as active iSAM problem in the literature. In addition to utilizing a robust MPC scheme, the active iSAM utilizes the optimization-based method, iSAM, to solve the simultaneous localization and mapping SLAM problem. Extensive numerical simulations have been conducted to verify the performance of the algorithm.

description: We have investigated the electronic states in quasi one dimensional (1D) CuO chains by microprobe Angle Resolved Photoemission Spectroscopy. We find that the quasiparticle Fermi surface consists of six disconnected segments, consistent with recent theoretical calculations that predict the formation of narrow, elongated Fermi surface pockets for coupled CuO chains. In addition, we find a strong renormalization effect with a significant kink structure in the band dispersion. The properties of this latter effect [energy scale (~40 meV), temperature dependence and behavior with Zn-doping] are identical to those of the bosonic mode observed in CuO2 planes of high temperature superconductors, indicating they have a common origin.

description: AA Dor is an eclipsing, post common-envelope binary with an sdOB-type primary and a low-mass secondary. Eleven years ago, an NLTE spectral analysis showed a discrepancy in the surface gravity that was derived by radial-velocity and light-curve analysis, log g = 5.21 +/- 0.1 (cm/sec^2) and log g = 5.53 +/- 0.03, respectively. We aim to determine both the effective temperature and surface gravity of AA Dor precisely from high-resolution, high-S/N observations taken during the occultation of the secondary. We calculated an extended grid of metal-line blanketed, state-of-the-art, non-LTE model atmospheres in the parameter range of the primary of AA Dor. Synthetic spectra calculated from this grid were compared to optical observations. We verify Teff = 42000 +/- 1000 K from our former analyses and determine a higher log g = 5.46 +/- 0.05. The main reason are new Stark-broadening tables that were used for calculating of the theoretical Balmer-line profiles. Our result for the surface gravity agrees with the value from light-curve analysis within the error limits, thereby solving the so-called gravity problem in AA Dor.

Seismic vulnerability assessment of wall pier highway bridges in British Columbia
Creators: name: Siddiquee, Kader Newaj
Publisher: name: University of British Columbia
Year: 2015

description: British Columbia, recognized as the most earthquake prone region in Canada, has a transportation network consisting of more than 2500 highway bridges. Failure of bridges due to any future seismic event might have a catastrophic impact on the province’s highway network. Many of the bridges in this region are very old and were constructed without proper seismic detailing. Moreover, by introducing performance based design (PBD) approaches in the proposed Canadian Highway Bridge Design Code (CHBDC), probabilistic seismic assessment of existing bridges have become essential. In this study, fragility analysis is performed to assess the seismic performance of the existing wall pier highway bridges in BC which is one of the major bridge types in BC region. Fragility curves for critical bridge components and for the entire bridge system are generated which provide the probability of exceeding any specific performance level under a certain ground motion intensity. Estimation of wall pier capacity limit states for these different performance levels is also part of this study which is crucial for performance based design of wall pier bridges. In order to accurately simulate the behavior of such wall pier bridges in BC, a comprehensive bridge inventory analysis is performed to determine their dimensions, shapes, span length etc. Analytical 3D models of 180 wall pier bridges with three different soil types, as per CHBDC, are generated combining different structural and geometrical uncertainties from the inventory. From the nonlinear dynamic time history analyses of these bridge models, fragility curves for slight, minimal, repairable and near collapse damage are generated. Fragility curves highlight the elastomeric bearing as the most vulnerable component followed by wall pier and abutment back wall. While estimating the seismic vulnerability, these fragility curves can also provide resourceful information for developing a retrofitting prioritization plan for wall pier bridges in BC. Besides the information presented in the inventory will aid in establishing an efficient Bridge Management System (BMS) and a possible National Bridge Inventory for Canada.

All our results indicate that a harmonic-oscilator spectrum with universal frequency, in combination with coupled-channel effects, does a much better job than the q-barq spectrum of the funnel potential.

description: We study Fiske steps in small Bi2Sr2CaCu2O8+x mesa structures, containing only few stacked intrinsic Josephson junctions. Careful alignment of magnetic field prevents penetration of Abrikosov vortices and facilitates observation of a large variety of high quality geometrical resonances, including superluminal with velocities larger than the slowest velocity of electromagnetic waves. A small number of junctions limits the number of resonant modes and allows accurate identification of modes and velocities. It is shown that superluminal geometrical resonances can be excited by subluminal fluxon motion and that flux-flow itself becomes superluminal at high magnetic fields. We argue that observation of high-quality superluminal geometrical resonances is crucial for realization of the coherent flux-flow oscillator in the THz frequency range.

description: Recently, Dial et al. presented measurements of the tunneling density of states into the bulk of a two dimensional electron gas under strong magnetic fields. Several high energy features appear in the measured spectrum showing a distinct dependence on filling factor and a unique response to temperature. We present a quantitative account of the observed structure, and argue it results from the repulsive Coulomb interactions between the tunneling electron and states localized at disorder potential wells. The quenching of the kinetic energy by the applied magnetic field leads to an electron addition spectrum that is primarily determined by the external magnetic field and is nearly independent of the disorder potential. Using a Hartree-Fock model we reproduce the salient features of the observed structure.

description: We investigate the Berezin integral of non-compactly supported quantities. In the framework of supermanifolds with corners, we give a general, explicit and coordinate-free repesentation of the boundary terms introduced by an arbitrary change of variables. As a corollary, a general Stokes's theorem is derived - here, the boundary integral contains transversal derivatives of arbitrarily high order.

description: We study the thermodynamics and the phase structures of Reissner-Nordstrom and Born-Infeld black holes in AdS space by constructing ``off-shell'' free energies using thermodynamic quantities derived directly from the action. We then use these results to propose ``off-shell'' effective potentials for the respective boundary gauge theories. The saddle points of the potentials describe all the equilibrium phases of the gauge theories.

Mitochondrial transcription factor A (TFAM) as a novel intercellular signaling molecule of the brain : its role in glial cell activation and neuroinflammation

description: Microglia, a subtype of non-neuronal glial cells, represent the innate immune system of the brain. In Alzheimer’s disease, chronic neuroinflammation caused by dysregulated activation of microglia (termed microgliosis) contributes to neuronal cell death. Endogenous molecules including damage-associated molecular patterns (DAMPs) have been implicated as triggers of microgliosis. High mobility group box 1 (HMGB1), a well-characterized DAMP, induces inflammatory responses from several cell types when released into the extracellular space. Mitochondrial transcription factor A (TFAM), a structural and functional homolog of HMGB1, has been implicated as a possible DAMP. However, the effects of TFAM on glial and neuronal cells of the central nervous system remain unknown. This thesis demonstrates that extracellular TFAM acts as a DAMP capable of inducing pro-inflammatory and cytotoxic responses in glial cells by engaging receptors similar to those activated by HMGB1. Stimulation of THP-1 cells (microglia model) with TFAM in combination with interferon (IFN)-γ, resulted in activation of these cells, as demonstrated by a significant decrease in SH-SY5Y neuronal cell viability after their exposure to the supernatants from stimulated THP-1 cells. Similar results were obtained using the U-118 MG astrocytic cell line and primary human astrocytes. The induced neurotoxicity was accompanied by the release of monocyte chemotactic protein-1 (MCP-1), reactive oxygen species (ROS), and novel intercellular signaling agents called microparticles (MPs). These MPs, in turn, induced THP-1 cell activation in an autocrine manner. Furthermore, my data demonstrate that the receptor for advanced glycation endproducts (RAGE) and the macrophage antigen complex-1 (Mac-1) receptor are engaged by TFAM, as blocking these receptors with specific inhibitors (heparin and soluble RAGE) or antibodies attenuated glial toxicity towards neuronal cells, and decreased the secretion of MCP-1 and ROS. Lastly, TFAM expression in U-373 MG astrocytic cells and primary human astrocytes was upregulated in response to treatment with hydrogen peroxide. This research provides insight into glial activation by TFAM, and the role of endogenous intercellular signaling molecules in communication between different central nervous system cell types. Moreover, identification of the glial receptors targeted by TFAM may provide novel therapeutic targets for pathologies involving sterile neuroinflammatory processes including Alzheimer’s disease.

description: The multiple testing procedure plays an important role in detecting the presence of spatial signals for large-scale imaging data. Typically, the spatial signals are sparse but clustered. This paper provides empirical evidence that for a range of commonly used control levels, the conventional $\operatorname {FDR}$ procedure can lack the ability to detect statistical significance, even if the $p$-values under the true null hypotheses are independent and uniformly distributed; more generally, ignoring the neighboring information of spatially structured data will tend to diminish the detection effectiveness of the $\operatorname {FDR}$ procedure. This paper first introduces a scalar quantity to characterize the extent to which the "lack of identification phenomenon" ($\operatorname {LIP}$) of the $\operatorname {FDR}$ procedure occurs. Second, we propose a new multiple comparison procedure, called $\operatorname {FDR}_L$, to accommodate the spatial information of neighboring $p$-values, via a local aggregation of $p$-values. Theoretical properties of the $\operatorname {FDR}_L$ procedure are investigated under weak dependence of $p$-values. It is shown that the $\operatorname {FDR}_L$ procedure alleviates the $\operatorname {LIP}$ of the $\operatorname {FDR}$ procedure, thus substantially facilitating the selection of more stringent control levels. Simulation evaluations indicate that the $\operatorname {FDR}_L$ procedure improves the detection sensitivity of the $\operatorname {FDR}$ procedure with little loss in detection specificity. The computational simplicity and detection effectiveness of the $\operatorname {FDR}_L$ procedure are illustrated through a real brain fMRI dataset.

description: We perform 3+1 general relativistic simulations of rotating core collapse in the context of the collapsar model for long gamma-ray bursts. We employ a realistic progenitor, rotation based on results of stellar evolution calculations, and a simplified equation of state. Our simulations track self-consistently collapse, bounce, the postbounce phase, black hole formation, and the subsequent early hyperaccretion phase. We extract gravitational waves from the spacetime curvature and identify a unique gravitational wave signature associated with the early phase of collapsar formation.

The Capacity Region of Multiway Relay Channels Over Finite Fields with Full Data Exchange

description: The multi-way relay channel is a multicast network where L users exchange data through a relay. In this paper, the capacity region of a class of multi-way relay channels is derived, where the channel inputs and outputs take values over finite fields. The cut-set upper bound to the capacity region is derived and is shown to be achievable by our proposed functional-decode-forward coding strategy. More specifically, for the general case where the users can transmit at possibly different rates, functional-decode-forward, combined with rate splitting and joint source-channel decoding, is proved to achieve the capacity region; while for the case where all users transmit at a common rate, rate splitting and joint source-channel decoding are not required to achieve the capacity. That the capacity-achieving coding strategies do not utilize the users' received signals in the users' encoding functions implies that feedback does not increase the capacity region of this class of multi-way relay channels.
