description: The role of electron-electron interactions is analyzed for Rashba-like and spin-split systems within a tight-binding single-band Hubbard model with on-site and all nearest-neighbor matrix elements of the Coulomb interaction. By Rashba-like systems we refer to the Dresselhaus and Rashba spin-orbit coupled phases; spin-split systems have spin-up and spin-down Fermi surfaces shifted relative to each other. Both systems break parity but preserve time-reversal symmetry. They belong to a class of symmetry-breaking ground states that satisfy: (i) electron crystal momentum is a good quantum number (ii) these states have no net magnetic moment and (iii) their distribution of `polarized spin' in momentum space breaks the lattice symmetry. In this class, the relevant Coulomb matrix elements are found to be nearest-neighbor exchange $J$, pair-hopping $J'$ and nearest-neighbor repulsion $V$. These ground states lower their energy most effectively through $J$, hence we name them Class $J$ states. The competing effects of $V-J'$ on the direct and exchange energies determine the relative stability of Class $J$ states. We show that the spin-split and Rashba-like phases are the most favored ground states within Class $J$ because they have the minimum anisotropy in `polarized spin'. On a square lattice we find that the spin-split phase is always favored for near-empty bands; above a critical filling, we predict a transition from the paramagnetic to the Rashba-like phase at $ J_{c1}$ and a second transition to the spin-split state at $J_{c2}>J_{c1}$. An energetic comparison with ferromagnetism highlights the importance of the role of $V$ in the stability of Class $J$ states. We discuss the relevance of our results to (i) the $α$ and $β$ phases proposed by Wu and Zhang in the Fermi Liquid formalism and (ii) experimental observations of spin-orbit splitting in \emph{Au}(111) surface states.

description: This work aims to analyse the relationship between Text and Data Mining (TDM), i.e. those techniques that allow to derive useful information from the computational analysis of data and texts, and intellectual property law, in particular copyright and database protection law. A first chapter, which will introduce the reader to the subject of TDM and some of its technical features, as well as its economic potential and practical applications and the main legal issues encountered in its use, namely intellectual property and data protection law, is followed by a second chapter that deals specifically with copyright and its relationship with technological innovation. The chapter will start by introducing the rights that copyright provides, and the justifications for them, their exceptions and the difficult balancing of interests in regulating them. In the second part of the chapter, the history of copyright will be investigated, starting from its origins, going through the different phases of its evolution, up to the present day, concluding how the initially well-considered balance of interests has been lost, gradually shifting towards the private interests of authors and publishers, to the detriment of the public interest. The third chapter focuses on the problems and obstacles to TDM and on the solutions that were provided in the European context, focusing in particular on the relationship between TDM activities and the rights and exceptions to copyright and database protection as provided by the InfoSoc Directive and Database Directive. The second part deals with the long process that finally led to the recent introduction of two exceptions for TDM by the Directive on Copyright in the Digital Single Market of 2019, thus analysing in detail these clauses, presenting their numerous criticisms and advancing some alternative solutions proposed by European scholars to the issue. The fourth chapter looks at the phenomenon from a comparative perspective, analysing and comparing the different approaches adopted by the main world powers, such as, among others, the United States, Japan and China.

description: The transport properties of finite nanotubes placed in a magnetic field parallel to their axes are investigated. Upon including spin-orbit coupling and curvature effects, two main phenomena are analyzed which crucially depend on the tube's chirality: i) Finite carbon nanotubes in a parallel magnetic field may present a suppression of current due to the localization at the edges of otherwise conducting states. This phenomenon occurs due to the magnetic-field dependent open boundary conditions obeyed by the carbon nanotube's wave functions. The transport is fully suppressed above threshold values of the magnetic field which depend on the nanotube chirality, length and on the spin-orbit coupling. ii) Reversible spin polarized currents can be obtained upon tuning the magnetic field, exploiting the curvature-induced spin-orbit splitting.

Discovery of novel androgen receptor inhibitors as prospective therapeutics for advanced prostate cancer
Creators: name: Li, Huifang
Publisher: name: University of British Columbia
Year: 2015

description: Prostate cancer (PCa) is the most commonly diagnosed cancer in men, and the second leading cause of male cancer death in North America. The androgen signalling pathway plays a central role in the development and advancement of PCa as well as in its progression to a lethal castration-resistant stage (CRPC). The human androgen receptor (AR) is a master regulator of PCa progression and survival, and a well-validated drug target for PCa. All clinically used AR inhibitors (antiandrogens) are initially effective to PCa; however, they invariably cause resistance. Thus, there is a continuing need for developing novel anti-AR drugs for the treatment of PCa and CRPC. Although the mechanism of resistance to antiandrogens is not completely clear, it involves mutation-driven antagonist-to-agonist transformation of the AR response, and the emergence of AR splice variants (ARVs) lacking the entire ligand-binding domain (LBD) of the protein. This dissertation describes the discovery and development of novel AR inhibitors directed towards the conventional androgen binding site (ABS) of the receptor, as well as the discovery of an entirely novel class of inhibitors targeting the DNA-binding domain (DBD) of the AR. Both types of AR inhibitors were identified through virtual screening and molecular modeling, followed by in vitro and/or in vivo validation of developed drug prototypes. The objective of developing novel chemotypes for ABS binders and AR DBD inhibitors is to help circumvent drug resistance problem in the field of PCa.

description: We show that the dilute Fermi gas quantum critical universality class quantitatively describes the Mott/metal crossover of the two-dimensional Hubbard model for temperatures somewhat less than (roughly half) the tunneling but much greater than (roughly twice) the superexchange energy. We calculate the observables expected to be universal near the transition --- density and compressibility --- with numerically exact determinantal quantum Monte Carlo. We find they are universal functions of the chemical potential. Despite arising from the strongly correlated regime of the Hubbard model, these functions are given by the weakly interacting, dilute Fermi gas model. These observables and their derivatives are the only expected universal static observables of this universality class, which we also confirm by verifying there is no scaling collapse of the kinetic energy, fraction of doubly occupied sites, and nearest neighbor spin correlations. Our work resolves the universality class of the intermediate temperature Mott/metal crossover, which had alternatively been proposed to be described by more exotic theories. However, in the presence of a Zeeman magnetic field, we find that interplay of spin with itinerant charge can lead to physics beyond the dilute Fermi gas universality class.

description: We consider the Gel'fand inverse problem and continue studies of [Mandache,2001]. We show that the Mandache-type instability remains valid even in the case of Dirichlet-to-Neumann map given on the energy intervals. These instability results show, in particular, that the logarithmic stability estimates of [Alessandrini,1988], [Novikov,Santacesaria,2010] and especially of [Novikov,2010] are optimal (up to the value of the exponent).

description: In 1917, as America entered into the Great War, Indigenous responses to the war effort were diverse and complex. The Great War tested Native Americans’ ambiguous position both inside and outside the American nation. Assimilationists read the massive outpouring of support for the war effort as a validation of federal Indian policies, yet failed to recognize that Indigenous people also held loyalties to their own their tribal nations, their family and kin, and their ancestral homelands. While Native Americans overwhelmingly supported the war, both at home and at the front, they recognized that universal registration and compulsory military service touched upon citizenship questions and meant an infringement on their tribal sovereignty and their guaranteed treaty rights.

For each type of possible soliton pairs stability ranges are presented in tabulated form. We also compare the numerically established stability of bright-bright, bright-dark and dark-dark solitons with our analytical prediction and with that of Painlevé-analysis of the dynamical equation. We demonstrate that tuning the inter-species scattering length away from the predicted value (keeping the intra-species coupling fixed) breaks the stability of the soliton pairs.

description: We present a comprehensive spectral-timing study of the black hole candidate MAXI J1659-152 during its 2010 outburst. We analysed 65 RXTE observations taken along this period and computed the fundamental diagrams commonly used to study black hole transients. We fitted power density and energy spectra and studied the evolution of the spectral and timing parameters along the outburst. We discuss the evolution of the variability observed at different energy bands on the basis of the relative contribution of the disc and hard components to the energy spectrum of the source. We conclude that hard emission accounts for the observed fast variability, it being strongly quenched when type-B oscillations are observed. We find that both disc and hard emission are responsible for local count-rate peaks until the system reaches the soft state. From that point, the peaks are only observed in the hard component, whereas the thermal component drops monotonically probably following the accretion rate decrease. We have also computed time-lags between soft and hard X-ray variability confirming that lags are larger during the hard-to-soft transition than during the hard state.

description: The zero temperature value of the in-plane London penetration depth, $λ_{ab}(0)$, has been measured in single crystals of Ba(Fe$_{1-x}$Co$_x$)$_2$As$_2$ as a function of the Co concentration, $x$, across both the underdoped and overdoped superconducting regions of the phase diagram. For $x\gtrsim0.047$, $λ_{ab}(0)$ has been found to have values between 120 $\pm$ 50~nm and 300 $\pm$ 50~nm. A pronounced increase in $λ_{ab}(0)$, to a value as high as 950 $\pm$ 50~nm, has been observed for $x\lesssim0.047$, corresponding to the region of the phase diagram where the itinerant antiferromagnetic and superconducting phases coexist and compete. Direct determination of the doping-dependent $λ_{ab}(0)$ has allowed us to track the evolution of the temperature-dependent superfluid density, from which we infer the development of a pronounced superconducting gap anisotropy at the edges of the superconducting dome.

description: A subset S of vertices of a graph G is called a k-path vertex cover if every path of order k in G contains at least one vertex from S. Denote by ψ_k(G) the minimum cardinality of a k-path vertex cover in G. It is shown that the problem of determining ψ_k(G) is NP-hard for each k \geq 2, while for trees the problem can be solved in linear time. We investigate upper bounds on the value of ψ_k(G) and provide several estimations and exact values of ψ_k(G). We also prove that ψ_3(G) \leq (2n + m)/6, for every graph G with n vertices and m edges.

ANIMA D3.2 - Development of indicators for night noise protection zones
Creators: name: Müller, Uwe
Publisher: name: Zenodo
Year: 2021

description: The present deliverable pursues the principle of minimizing acute effects (additional aircraft noise induced awakening reactions) so that long-term consequences (increased health risks) do not occur. For this aim, the analysis of the data from the currently only two worldwide available field studies on the impact of aircraft noise on sleep, that used the “gold standard” polysomnography for sleep and simultaneous acoustical measurements, have been improved and a pooled analysis was operated. The data were measured at one airport with continuous nocturnal aircraft noise (Cologne/Bonn) and at the other airport with a night flight ban between 11 pm and 5 am but very busy traffic in the shoulder hours (Frankfurt airport).
 The results show that the probability to awake from an aircraft overflight (aircraft noise event) with the same maximum level in both cases just differs within the reasonable confidence intervals so that the results of the exposure-response function of the pooled data promise a fairly good transferability to other airports.

Detection of Anomalous Reactor Activity Using Antineutrino Count Rate Evolution Over the Course of a Reactor Cycle

Year: 2010
Subjects: subject: Nuclear Experiment (nucl-ex)

description: This paper analyzes the sensitivity of antineutrino count rate measurements to changes in the fissile content of civil power reactors. Such measurements may be useful in IAEA reactor safeguards applications. We introduce a hypothesis testing procedure to identify statistically significant differences between the antineutrino count rate evolution of a standard 'baseline' fuel cycle and that of an anomalous cycle, in which plutonium is removed and replaced with an equivalent fissile worth of uranium. The test would allow an inspector to detect anomalous reactor activity, or to positively confirm that the reactor is operating in a manner consistent with its declared fuel inventory and power level. We show that with a reasonable choice of detector parameters, the test can detect replacement of 73 kg of plutonium in 90 days with 95% probability, while controlling the false positive rate at 5%. We show that some improvement on this level of sensitivity may be expected by various means, including use of the method in conjunction with existing reactor safeguards methods. We also identify a necessary and sufficient daily antineutrino count rate to achieve the quoted sensitivity, and list examples of detectors in which such rates have been attained.

title: Adaptive vehicular networking with Deep Learning
Creators: name: Tan, Kang
Publisher: name: University of Glasgow
Year: 2023

description: Vehicular networks have been identified as a key enabler for future smart traffic applications aiming to improve on-road safety, increase road traffic efficiency, or provide advanced infotainment services to improve on-board comfort. However, the requirements of smart traffic applications also place demands on vehicular networks’ quality in terms of high data rates, low latency, and reliability, while simultaneously meeting the challenges of sustainability, green network development goals and energy efficiency. The advances in vehicular communication technologies combined with the peculiar characteristics of vehicular networks have brought challenges to traditional networking solutions designed around fixed parameters using complex mathematical optimisation. These challenges necessitate greater intelligence to be embedded in vehicular networks to realise adaptive network optimisation. As such, one promising solution is the use of Machine Learning (ML) algorithms to extract hidden patterns from collected data thus formulating adaptive network optimisation solutions with strong generalisation capabilities. In this thesis, an overview of the underlying technologies, applications, and characteristics of vehicular networks is presented, followed by the motivation of using ML and a general introduction of ML background. Additionally, a literature review of ML applications in vehicular networks is also presented drawing on the state-of-the-art of ML technology adoption. Three key challenging research topics have been identified centred around network optimisation and ML deployment aspects. The first research question and contribution focus on mobile Handover (HO) optimisation as vehicles pass between base stations; a Deep Reinforcement Learning (DRL) handover algorithm is proposed and evaluated against the currently deployed method. Simulation results suggest that the proposed algorithm can guarantee optimal HO decision in a realistic simulation setup. The second contribution explores distributed radio resource management optimisation. Two versions of a Federated Learning (FL) enhanced DRL algorithm are proposed and evaluated against other state-of-the-art ML solutions. Simulation results suggest that the proposed solution outperformed other benchmarks in overall resource utilisation efficiency, especially in generalisation scenarios. The third contribution looks at energy efficiency optimisation on the network side considering a backdrop of sustainability and green networking. A cell switching algorithm was developed based on a Graph Neural Network (GNN) model and the proposed energy efficiency scheme is able to achieve almost 95% of the metric normalised energy efficiency compared against the “ideal” optimal energy efficiency benchmark and is capable of being applied in many more general network configurations compared with the state-of-the-art ML benchmark.

description: The ultra-luminous X-ray (ULXs) pulsar NGC 7793 P13 is one of only a handful confirmed neutron stars in an 19.5 ULX and can reach luminosities above 1040 erg/s, more than 20x its Eddington luminosity. It shows very strong pulsations with a pulse period around 415ms. We’ve been monitoring the pulsations over the last years and 21 used them to determine the orbital period to be ~65d. In addition, P13 shows a very strong long-term flux period in the X-rays and the optical/UV, with periods close to but significantly different to the orbital period. Understanding the pulse period evolution and its connection to the overall flux and flux variability will help us gain important insights into super Eddington accretion flows.

description: The fragmentation of shocked flows in a thermally bistable medium provides a natural mechanism to form turbulent cold clouds as precursors to molecular clouds. Yet because of the large density and temperature differences and the range of dynamical scales involved, following this process with numerical simulations is challenging. We compare two-dimensional simulations of flow-driven cloud formation without self-gravity, using the Lagrangian Smoothed Particle Hydrodynamics (SPH) code VINE and the Eulerian grid code Proteus. Results are qualitatively similar for both methods, yet the variable spatial resolution of the SPH method leads to smaller fragments and thinner filaments, rendering the overall morphologies different. Thermal and hydro-dynamical instabilities lead to rapid cooling and fragmentation into cold clumps with temperatures below 300K. For clumps more massive than 1 Msun/pc, the clump mass function has an average slope of -0.8. The internal velocity dispersion of the clumps is nearly an order of magnitude smaller than their relative motion, rendering it subsonic with respect to the internal sound speed of the clumps, but supersonic as seen by an external observer. For the SPH simulations most of the cold gas resides at temperatures below 100K, while the grid-based models show an additional, substantial component between 100 and 300K. Independently of the numerical method our models confirm that converging flows of warm neutral gas fragment rapidly and form high-density, low-temperature clumps as possible seeds for star formation.

In this stand-alone literature review*, the specific topic, the evolving environment of hybrid (virtual offsite and traditional ‘brick and mortar’) transnational organizations, is presented through the subtopics of organizational structure, design, management; and human resource policies and practices. The aim of the stand-alone literature review, defined as a detailed statement of what the review is intending to achieve, is to summarize, synthesize, and evaluate research regarding the impact of the hybrid (virtual offsite and traditional ‘brick and mortar’) practices in transnational organizations on structure, design, management; and human resources (Monash.edu, 2018).

* Whereas “a literature review that forms part of a research proposal or project also describes the gaps in the current knowledge that the project aims to address; a stand-alone literature review aims to summarize and evaluate the current knowledge of a specific topic” (Monash.edu, 2018).

description: All extra-solar planet masses that have been derived spectroscopically are lower limits since the inclination of the orbit to our line-of-sight is unknown except for transiting systems. It is, however, possible to determine the inclination angle, i, between the rotation axis of a star and an observer's line-of-sight from measurements of the projected equatorial velocity (v sin i), the stellar rotation period (P_rot) and the stellar radius (R_star). This allows the removal of the sin i dependency of spectroscopically derived extra-solar planet masses under the assumption that the planetary orbits lie perpendicular to the stellar rotation axis. We have carried out an extensive literature search and present a catalogue of v sin i, P_rot, and R_star estimates for exoplanet host stars. In addition, we have used Hipparcos parallaxes and the Barnes-Evans relationship to further supplement the R_star estimates obtained from the literature. Using this catalogue, we have obtained sin i estimates using a Markov-chain Monte Carlo analysis. This allows proper 1-sigma two-tailed confidence limits to be placed on the derived sin i's along with the transit probability for each planet to be determined. While a small proportion of systems yield sin i's significantly greater than 1, most likely due to poor P_rot estimations, the large majority are acceptable. We are further encouraged by the cases where we have data on transiting systems, as the technique indicates inclinations of ~90 degrees and high transit probabilities. In total, we estimate the true masses of 133 extra-solar planets. Of these, only 6 have revised masses that place them above the 13 Jupiter mass deuterium burning limit. Our work reveals a population of high-mass planets with low eccentricities and we speculate that these may represent the signature of different planetary formation mechanisms at work.

Pilot-scale microwave treatment of wastewater slurries : assessment of a 915 MHz microwave generator and custom applicator
Creators: name: Bailey, Samuel Willson
Publisher: name: University of British Columbia
Year: 2015

description: This study applied thermal-oxidative treatment to wastewater. It utilised a novel, pilot-scale microwave system with additions of hydrogen peroxide and acid. The system was instrumented to measure temperature, power and energy. This allowed aspects of process design, power draw and energy efficiency to be weighed against outcomes of treatment. Preliminary tests with salt water established procedures and expectations for the system, highlighting system sensitivity to variations in the target fluid. Primary tests treated manure and waste activated sludge, evaluating improvements in solids reduction, biogas production, dewaterability and nutrient recovery, each described by a suite of parameters, and referenced to power and energy consumed. Primary tests used various treatments, with some general trends observed. Acid solubilised inorganic constituents while fixing organics, improving settling and supernatant clarity. It had most acute effect on manure, achieving the majority of phosphorus released. Acid’s impact on phosphorus in sludge was less dramatic, though it produced a clear supernatant and good settling. For sludge, early addition of H₂O₂ and heat, or heat alone released most phosphorus and produced highest peaks in phosphate. However, results suggested that acid could be necessary to reduce suspended solids to a level required for struvite recovery. For both wastes, though especially dramatic for sludge, no acid, high heat and late addition of H₂O₂ proved best to disrupt organics and improve bulk parameters: dissolving most suspended solids; solubilising most carbon, volatile fatty acids and ammonia; and improving overall settling. This treatment indicated the most benefit for biogas production. This study shows some results similar to existing literature, though different processes may be used. This confirms a trend often noted in literature: that thermal treatments are largely reproducible, due to the dominant impact of heat. However, this study indicated that not all processes are equal in energy efficiency. Comparing continuous and semi-continuous operation, continuous runs showed slight detriment in treatment, but clear opportunity for improved energy efficiency. It increased stability in mechanical and chemical properties of target fluids, improving the stability and efficiency of microwave energy absorption.

description: The Kustin-Miller complex construction, due to A. Kustin and M. Miller, can be applied to a pair of resolutions of Gorenstein rings with certain properties to obtain a new Gorenstein ring and a resolution of it. It gives a tool to construct and analyze Gorenstein rings of high codimension. We describe the Kustin-Miller complex and its implementation in the Macaulay2 package KustinMiller, and explain how it can be applied to explicit examples.

Lithium Abundances in a Sample of Planet Hosting Dwarfs

description: This work presents a homogeneous determination of lithium abundances in a large sample of giant-planet hosting stars (N=117), and a control sample of disk stars without detected planets (N=145). The lithium abundances were derived using a detailed profile fitting of the Li I doublet at lambda 6708 A in LTE. The planet hosting and comparison stars were chosen to have significant overlap in their respective physical properties, including effective temperatures, luminosities, masses, metallicities and ages. The combination of uniform data and homogeneous analysis with well selected samples, makes this study well-suited to probe for possible differences in the lithium abundances found in planet hosting stars. An overall comparison between the two samples reveals no obvious differences between stars with and without planets. Closer examination of the behavior of the Li abundances over a narrow range of effective temperature (5700 K < Teff < 5850 K) indicates subtle differences between the two stellar samples; this temperature range is particularly sensitive to various physical processes that can deplete lithium. In this Teff range planet hosting stars have lower Li abundances (by ~0.26 dex on average) than the comparison stars, although this segregation may be influenced by combining stars from a range of ages, metallicities and masses. When stars with very restricted ranges in metallicity ([Fe/H] = 0.00 to +0.20 dex) and mass (M ~ 1.05 - 1.15 Msun are compared, however, both stars with and without planets exhibit similar behaviors in the lithium abundance with stellar age, suggesting that there are no differences in the lithium abundances between stars with planets and stars not known to have planets.

description: This study, based on an industry survey, shows that regulation by sanitary authorities cost fluid milk plants an estimated $3,895,637 in 1967. Of this total cost, $3,382,449 was for plant fees and $513,188 for other expenditures associated with plant inspections. Regulation by primary authorities accounted for 83.7 percent of the total cost and regulations by other authorities, 16.3 percent. The 1,249 plants reporting were regulated by an average of 4.8 sanitary authorities--one primary and 3.8 other. Plant inspections by these authorities averaged 23.9, of which three-fourths were primary. Significant differences existed between the sanitary requirements of authorities regulating many plants. These tended to restrict the flow of milk between markets, and lead to excessive duplication in plant inspections. Greater use of reciprocal agreements between sanitary authorities would reduce the amount and cost of duplicative regulation.
The Casimir interaction of a massive vector field between concentric spherical bodies

description: The Casimir interaction energy due to the vacuum fluctuations of a massive vector field between two perfectly conducting concentric spherical bodies is computed. The TE contribution to the Casimir interaction energy is a direct generalization of the massless case but the TM contribution is much more complicated. Each TM mode is a linear combination of a transverse mode which is the generalization of a TM mode in the massless case and a longitudinal mode that does not appear in the massless case. In contrast to the case of two parallel perfectly conducting plates, the are no TM discrete modes that vanish identically in the perfectly conducting spherical bodies. Numerical simulations show that the Casimir interaction force between the two bodies is always attractive.

description: We derive and investigate the dispersion relation for accretion disks with retarded or advanced heating. We follow the alpha-prescription but allow for a time offset (τ) between heating and pressure perturbations, as well as for a diminished response of heating to pressure variations. We study in detail solutions of the dispersion relation for disks with radiation-pressure fraction 1 - β. For τ<0 (delayed heating) the number and sign of real solutions for the growth rate depend on the values of the time lag and the ratio of heating response to pressure perturbations, ξ. If the delay is larger than a critical value (e.g., if Ωτ

description: Astronomy looks after its data better than most disciplines, and it is no coincidence that the consensus standard for the archival preservation of all types of digital assets -- the OAIS Reference Model -- emerged originally from the space science community. It is useful to highlight both what is different about astronomy (and indeed about Big Science in general), what could be improved, and what is exemplary, and in the process I will give a brief introduction to the framework of the OAIS model, and its useful conceptual vocabulary. I will illustrate this with a discussion of the spectrum of big-science data management practices from astronomy, through gravitational wave (GW) data, to particle physics.

A Geometric Algebra Perspective On Quantum Computational Gates And Universality In Quantum Computing

description: We investigate the utility of geometric (Clifford) algebras (GA) methods in two specific applications to quantum information science. First, using the multiparticle spacetime algebra (MSTA, the geometric algebra of a relativistic configuration space), we present an explicit algebraic description of one and two-qubit quantum states together with a MSTA characterization of one and two-qubit quantum computational gates. Second, using the above mentioned characterization and the GA description of the Lie algebras SO(3) and SU(2) based on the rotor group Spin+(3, 0) formalism, we reexamine Boykin's proof of universality of quantum gates. We conclude that the MSTA approach does lead to a useful conceptual unification where the complex qubit space and the complex space of unitary operators acting on them become united, with both being made just by multivectors in real space. Finally, the GA approach to rotations based on the rotor group does bring conceptual and computational advantages compared to standard vectorial and matricial approaches.
