GaN-based SEPIC DC-DC converters: design and performance comparisons
Creators: name: Ahmad, Viqar
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: The need for more efficient and compact DC-DC converter design has directed recent research to the use of Gallium Nitride (GaN) High Electron Mobility Transistors (HEMTs), capable of achieving higher switching speeds, in place of Silicon (Si) Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) which are nearing their theoretical maximum performance limit. The Single-ended Primary Inductor Converter (SEPIC) is one of the simplest designs of DC-DC converter with a relatively low component count, yet is capable of both buck and boost operation. A GaN-based current-regulated SEPIC, is therefore attractive for applications such as in solid state lighting; which is the prime focus of this research. This thesis reports work conducted to evaluate GaN HEMT’s performance against a Si FET with matching specifications. This comparison was carried out over a range of frequencies and duty cycles. The results of this work show a marked improvement in performance efficiency of GaN in comparison to Si over MHz frequency range. Moreover, a GaN-based SEPIC using discrete components having current regulation was developed. The underlying idea for building this circuit is to develop a regulated simple and efficient power supply, capable of being integrated for solid state lighting applications in the future.

description: In the half-filled zero-energy Landau level of bilayer graphene, competing phases with spontaneously broken symmetries and an intriguing quantum critical behavior have been predicted. Here we investigate signatures of these broken-symmetry phases in thermal transport measurements. To this end we calculate the spectrum of spin and valley waves in the $ν=0$ quantum Hall state of bilayer graphene. The presence of Goldstone modes enables heat transport even at low temperatures, which can serve as compelling evidence for spontaneous symmetry breaking. By varying external electric and magnetic fields it is possible to determine the nature of the symmetry breaking and temperature-dependent measurements may yield additional information about gapped modes.

The priming of seeds: investigations into a method of priming large quantities of seeds using salt solutions
Creators: name: Haigh, Anthony Mark
Publisher: name: Macquarie University
Year: 2022

description: Seed priming, which involves the hydration of seeds in an osmotic solution before sowing, produces seeds with improved germination performance. This study was aimed at optimizing the priming of tomato, carrot, onion and sorghum seeds by a method which could be readily scaled up for commercial use. -- Initially, to determine appropriate priming solutions, the germination responses of the four species to a range of osmotic potentials from 0 to -1.75 MPa in a range of osmotica - K₂HPO₄, K₃P0₄, KN0₃, K₂HPO₄ + KN0₃, K₃P0₄ + KN0₃ and Polyethylene glycol (PEG) - were investigated. -- The most effective priming treatment was shown to be one in which the osmoticum prevented germination without being toxi c, at a high osmotic potential. There were marked interactions between species, osmotic potential and the osmoticum used for priming. Tomato seeds were readily primed in any of the series of salt or PEG solutions . All of the solutions tried were adequate for carrot seeds. Onion seeds could be primed in either K₂HPO₄, K₃P0₄ or PEG solutions; however, all solutions were toxic to sorghum seeds or failed to prevent germination. -- The selected priming treatment was further optimized by experiments that investigated the influence of duration and temperature of priming. Priming at a lower temperature for a longer time was more beneficial than at higher temperatures. However, priming for too long a period was found to have adverse effects . Tomato seeds showed improved performance after priming for 16 t o 18 days at 15 C whereas for carrot seeds a duration of 8 to 10 days was adequate, but prolonged treatment led to reduced germination percentages. Columns of aerated solutions were found to be suitable for the priming of large quantities of tomato and carrot seeds. Air-drying of primed tomato and carrot seeds was possible without loss of germinability or priming effect. -- Limited field experiments at Yanco Agricultural Research Centre showed that primed tomato and carrot seeds emerged twice as fast as untreated seeds and had improved uniformity of emergence, particularly at low soil temperatures. These benefits from priming were maintained through to the first true leaf stage of development. -- It was concluded that it was possible to prime certain seeds in simple salt solutions by a method capable of expansion to commercial scales of operation and produce benefits to emergence which were maintained after drying to facilitate sowing using existing drilling equipment.

description: A combined mid-IR spectrum of five colliding-wind, massive, dust-producing Population I Wolf-Rayet (WR) binaries shows a wealth of absorption and emission details coming from the circumstellar dust envelopes, as well as from the interstellar medium. The prominent absorption features may arise from a mix of interstellar carbonaceous grains formed in high- (e.g., 3.4, 6.8, 7.2 $μ$m) and low-temperature (3.3, 6.9, 9.3 $μ$m) environments. The broad emission complexes around $\sim$6.5, 8.0 and 8.8 $μ$m could arise from ionized, small polycyclic aromatic hydrocarbon (PAH) clusters and/or amorphous carbonaceous grains. As such these PAH emissions may represent the long sought after precursors of amorphous Carbon dust. We also detect a strong $\sim$10.0 $μ$m emission in the spectra of WR48a and WR112, that we tentatively link to ionized PAHs. Upon examining the available archival spectra of prodigious individual WR dust sources, we notice a surprising lack of 7.7 $μ$m PAH band in the spectrum of the binary WR19, in contrast to the apparent strength of the 11.2, 12.7 and 16.4 $μ$m PAH features. Strong PAH emissions are also detected in the $λ>$10 $μ$m spectrum of another dust-producing system, WR118, pointing to the presence of large, neutral, presumably interstellar PAH molecules towards WR19 and WR118.

description: Order three elements in the exceptional groups of type G2 are classified up to conjugation over arbitrary fields. Their centralizers are computed, and the associated classification of idempotents in symmetric composition algebras is obtained. Idempotents have played a key role in the study and classification of these algebras. Over an algebraically closed field, there are two conjugacy classes of order three elements in G2 in characteristic not 3 and four of them in characteristic 3. The centralizers in characteristic 3 fail to be smooth for one of these classes.

Adaptive process model matching: improving the effectiveness of label-based matching through automated configuration and expert feedback
Creators: name: Klinkmüller, Christopher
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Process model matchers automate the detection of activities that represent similar functionality in different models. Thus, they provide support for various tasks related to the management of business processes including model collection management and process design. Yet, prior research primarily demonstrated the matchers' effectiveness, i.e., the accuracy and the completeness of the results. In this context, all data is used for the matcher development and the validity of the design decisions is not studied. A result of these shortcomings is that existing matchers yield a varying and typically low effectiveness when applied to different datasets. With that in mind, the thesis studies the effectiveness of matchers by separating development from evaluation data and by empirically analyzing the validity and the limitations of design decisions. In more detail, the thesis develops matching techniques that rely on different sources of information. First, the activity labels are considered as natural-language descriptions and the Bag-of-Words Technique is introduced. In comparison to the state of the art it achieves a high effectiveness. However, its effectiveness depends on the degree to which the underlying knowledge sources reflect the domain characteristics of the models. Moreover, it needs to be configured for each model collection which can require a huge manual effort. Second, the Order Preserving Bag-of-Words Technique analyzes control flow dependencies between activities in order to automatically configure the Bag-of-Words Technique and to maximize its effectiveness. Thus, it relieves experts from manually configuring the matchers. Third, expert feedback is used to adapt the matchers to the domain characteristics of process model collections and to further improve the effectiveness. Here, the Adaptive Bag-of-Words Technique is introduced. It analyzes expert feedback in order to continuously adjust the matching process and yields a strongly improved effectiveness. Consequently, it outperforms state-of-the-art matchers as well as the other matchers from this thesis.

description: Purpose: This study aimed to investigate the combined effects of moderate hypoxia with three different exercise modes on glucose regulation in healthy overweight adults. Methods: Thirteen overweight males (age: 31 ± 4 years; body fat 26.3 ± 3.2%) completed three exercise trials in a randomized crossover design involving 60 min cycling exercise at 90% lactate threshold (LOW), sprint interval training (20 × 4 s all-out; SIT) and lower limb functional bodyweight exercises (8 sets of 4 × 20 s; FEX) under moderate hypoxia (FiO2 = 16.5%). Post-exercise oral glucose tolerance test (OGTT) was performed following each trial. Heart rate, oxygen saturation (SpO2), physical activity enjoyment scale (PACES), and perceptual measures were recorded during each exercise session. Venous blood was collected pre-, immediately post-, and 24 h post-exercise and analysed for plasma glucose and insulin, incremental area under curve (iAUC), and circulating microRNA expression (c-miRs-486-5p, -126-5p, and -21-5p). Interstitial glucose concentrations were measured using continuous glucose monitoring (CGM). Results: Post-exercise OGTT iAUC for plasma glucose and insulin concentration were lower in SIT and LOW vs. control (p < 0.05) while post-exercise interstitial glucose iAUC and c-miRs were not different between exercise modes. Heart rate was greater in SIT vs. LOW and FEX, and FEX vs. LOW (p < 0.05), SpO2 was lower in SIT, while PACES was not different between exercise modes. Perceptual measures were greater in SIT vs. LOW and FEX. Conclusion: Acute SIT and LOW under moderate hypoxia improved post-exercise plasma insulin compared to FEX exercises. Considering SIT was also time-efficient, well tolerated, and enjoyable for participants, this may be the preferred exercise modality for improving glucose regulation in adult males with overweight when combined with moderate hypoxia.

When did the horse cross the road?: sequential effects in the go/no-go variable foreperiod paradigm
Creators: name: Wehrman, Jordan
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Timing is important to everyday functioning; performing the right action at the wrong time can be just as ineffective as performing the wrong action entirely. 'Inhibition' has been propsed to allow us to perform the correct response at the right time, and to stop that response completely if necessary. This thesis focuses on one theory linking inhibition and temporal expectancy, the 'trace-conditioning model' proposed by Los and van den Heuvel (2001). The trace-conditional model posits that imperative time points have associated traces which are reinforced/extinguished by inhibition based on events at that time point. Traces are proposed to explain the asymmetrical sequential foreperiod effect; a prior trial with a long foreperiod slows current short imperative reaction times, while a short imperative in the prior trial does not affect current trial long imperative reaction times. To further elaborate on how traces are controlled, I have performed three behavioural and one transcranial magnetic stimulation (TMS) experiment utilising varieties of the go/no-go variable foreperiod experiment as described by Los (2013). Each behavioural experiment manipulated the foreknowledge of an upcoming event, while the TMS experiment repeated Los’ study with the addition of a single TMS pulse 100ms after the short imperative time. By manipulating the foreknowledge of an upcoming event, I examined how trace-conditioning may interact with explicit information provided by cueing. TMS was applied to determine if corticospinal excitability was affected by prior trial dynamics. The behavioural experiments suggest that, while prior trial response effects were attenuated given response foreknowledge, temporal trace effects were not attenuated unless both response and temporal foreknowledge were provided. TMS results indicate prior trial timing, mediated by the current trial type, affected motor cortex excitability. I argue that these findings indicate a separation between response and temporal traces.

Semantics and pragmatics of religious formulae used by teachers in Saudi Arabian classroom talk

Subjects: Other education not elsewhere classified

description: This project investigates the use of Arabic Religious Formulae (henceforth, RFs) in Saudi Arabic teacher-student talk. It is underpinned by Speech Act Theory, Natural Semantic Metalanguage (NSM) and its offshoot, Cultural Script Theory. Ethnographic methods were used to collect data and Conversation Analysis (CA) was crucial for transcribing data, shedding further light on the cultural significance of the speech acts and RFs used in teacher-student interaction. Thirty teachers from a range of disciplines were observed and audio-taped twice. A focus group discussion was conducted after the observation period in order to gather speakers’ insights about their use of religious formulae. This triangulation reveals a wide range of communication functions and pragmatic roles that RFs can play in interactions. In addition, it identifies precisely the social and cultural embeddedness of the occurrence of RFs in Arabic teacher-student talk. The findings are original in revealing the characteristics of RFs, the way they construct speech acts, and how speakers challenge the ambiguous use of RFs. The study also contributes to our understanding of the cultural value of using RFs as part of a Saudi teacher role. iv

description: We operate a resonant exchange qubit in a highly symmetric triple-dot configuration using IQ-modulated RF pulses. At the resulting three-dimensional sweet spot the qubit splitting is an order of magnitude less sensitive to all relevant control voltages, compared to the conventional operating point, but we observe no significant improvement in the quality of Rabi oscillations. For weak driving this is consistent with Overhauser field fluctuations modulating the qubit splitting. For strong driving we infer that effective voltage noise modulates the coupling strength between RF drive and the qubit, thereby quickening Rabi decay. Application of CPMG dynamical decoupling sequences consisting of up to n = 32 π pulses significantly prolongs qubit coherence, leading to marginally longer dephasing times in the symmetric configuration. This is consistent with dynamical decoupling from low frequency noise, but quantitatively cannot be explained by effective gate voltage noise and Overhauser field fluctuations alone. Our results inform recent strategies for the utilization of partial sweet spots in the operation and long-distance coupling of triple-dot qubits.

description: We generalize the curved $N$-body problem to spheres and hyperbolic spheres whose curvature $κ$ varies in time. Unlike in the particular case when the curvature is constant, the equations of motion are non-autonomous. We first briefly consider the analogue of the Kepler problem and then investigate the homographic orbits for any number of bodies, proving the existence of several such classes of solutions on spheres. Allowing the curvature to vary in time offers some insight into the effect of an expanding universe, in the context the curved $N$-body problem, when $κ$ satisfies Hubble's law. The study of these equations also opens the possibility of finding new connections between classical mechanics and general relativity.

description: We investigate the hierarchies of half-supersymmetric branes in maximal supergravity theories. By studying the action of the Weyl group of the U-duality group of maximal supergravities we discover a set of universal algebraic rules describing the number of independent 1/2-BPS p-branes, rank by rank, in any dimension. We show that these relations describe the symmetries of certain families of uniform polytopes. This induces a correspondence between half-supersymmetric branes and vertices of opportune uniform polytopes. We show that half-supersymmetric 0-, 1- and 2-branes are in correspondence with the vertices of the $k_{21}$ , $2_{k1}$ and $1_{k2}$ families of uniform polytopes, respectively, while 3-branes correspond to the vertices of the rectified version of the $2_{k1}$ family. For 4-branes and higher rank solutions we find a general behavior. The interpretation of half-supersymmetric solutions as vertices of uniform polytopes reveals some intriguing aspects. One of the most relevant is a triality relation between 0-, 1- and 2-branes.

Subjects: subject: 330 - Wirtschaft

description: This paper critically reviews literature on the role of Mobile Instant Messaging (MIM) applications, such as WhatsApp, in supporting learning and teaching practice. Using formal qualitative synthesis as its methodology, and dialectical theory as an analytical framework, our main objective was to identify tensions, affordances, constraints, and resolution strategies in educational uses of MIM. In contrast to prior work, the analysis offers a nuanced and complex picture of the use of MIM in learning and teaching settings. Instead of facilitating the creation of educational outcomes in a straightforward manner, the realities of MIM use are socially constructed and the subject of conflictual negotiations. The educational use of MIM requires users to navigate the interdependent dialectical tensions of immediacy versus delays (temporal dimension), intimacy versus detachment (relationship dimension) and task versus ludic orientation (intellectual dimension). The findings also reveal a number of behavioural and technical resolution strategies that users deploy to manage these tensions.

Meaningful relationships in foster care: an interpretive inquiry of supervising social workers within three independent fostering providers
Creators: name: Byrne, Pennie
Publisher: name: Anglia Ruskin Research Online (ARRO)
Year: 2024

description: Background: In England, nearly half (45%) of all children and young people in mainstream foster carer are in care provided by independent foster care providers (IFPs) (Department for Education, 2022). Yet, little is known about the relationships held between children and young people and their foster carers, nor the extent of the support they receive from their IFP, and its impact on their relationships. Focusing on the role of supervising social workers (SSWs) within three English-based IFPs, this study asks the question: ‘What are the essential factors and interpersonal qualities SSWs need to assist children and their foster carers in building and maintaining a meaningful relationship?’Methodology: This study has involved interpretive qualitative semi-structured interviews with three groups of four participants; a young person over the age of 16, their foster carer(s), their allocated SSW and their social work manager from three different IFPs, making a total of 13 participants. In each context, close attention is focused on the participants' voices and their own constructions of the relationship between the young people and their foster carers and the impact that the SSW may have had on their relationships.Findings: The study was not about good versus bad social work but how the SSWs position themselves and engage with the young people and their foster carers. The study’s rich findings provide a rare view into the way SSWs within three IFPs have improved relationship outcomes for young people and their foster carers through their statutory role, personal involvement and interpersonal skills, thereby demonstrating that SSWs are not working from the sideline.Conclusions: This explorative study adds to what is currently known about the importance of attachment for children looked after and their foster carers, as well as relationship-based social work. Furthermore, it highlights the advantages of SSWs spending more time with the children being cared for by the foster carers they supervise and support. This goes beyond customary practice for SSWs in England.

description: Giant planets are thought to have cores in their deep interiors, and the division into a heavy-element core and hydrogen-helium envelope is applied in both formation and structure models. We show that the primordial internal structure depends on the planetary growth rate, in particular, the ratio of heavy elements accretion to gas accretion. For a wide range of likely conditions, this ratio is in one-to-one correspondence with the resulting post-accretion profile of heavy elements within the planet. This flux ratio depends sensitively on the assumed solid surface density in the surrounding nebula. We suggest that giant planets' cores might not be distinct from the envelope and includes some hydrogen and helium, and the deep interior can have a gradual heavy-element structure. Accordingly, Jupiter's core may not be well-defined. Accurate measurements of Jupiter's gravitational field by Juno could put constraints on Jupiter's core mass. However, as we suggest here, the definition of Jupiter's core is complex, and the core's physical properties (mass, density) depend on the actual definition of the core and on its growth history.

description: The Web has been around and maturing for 25 years. The popular websites of today have undergone vast changes during this period, with a few being there almost since the beginning and many new ones becoming popular over the years. This makes it worthwhile to take a look at how these sites have evolved and what they might tell us about the future of the Web. We therefore embarked on a longitudinal study spanning almost the whole period of the Web, based on data collected by the Internet Archive starting in 1996, to retrospectively analyze how the popular Web as of now has evolved over the past 18 years. For our study we focused on the German Web, specifically on the top 100 most popular websites in 17 categories. This paper presents a selection of the most interesting findings in terms of volume, size as well as age of the Web. While related work in the field of Web Dynamics has mainly focused on change rates and analyzed datasets spanning less than a year, we looked at the evolution of websites over 18 years. We found that around 70% of the pages we investigated are younger than a year, with an observed exponential growth in age as well as in size up to now. If this growth rate continues, the number of pages from the popular domains will almost double in the next two years. In addition, we give insights into our data set, provided by the Internet Archive, which hosts the largest and most complete Web archive as of today.

description: Inferring ecological patterns from marine survey data is difficult due to the large spatial and temporal scales at which processes operate and the challenges associated with collecting comprehensive and balanced survey data. In this thesis I use large scale survey data and cutting edge modelling techniques to examine the drivers of species distribution in the Southern Ocean at three trophic levels - primary producers, grazers and top predators. I develop a model to predict phytoplankton abundance in a 3D environment from temperature, salinity and depth. This framework is widely applicable to other marine settings regardless of their survey design and provides a robust method for dealing with complex data sets. An important grazer on phytoplankton, Antarctic krill (Euphausia superba), has previously been regarded as passively drifting with large scale current systems. I provide quantitative evidence that they actively swim, demonstrating that krill consistently aggregate around resources over an immense survey area spanning 1.3 million km2. Krill distribution is patchy, and predators must locate these dynamic swarms across vast expanses of ocean. Islands may provide predictable and reliable feeding areas due to the Island Mass Effect. I find that krill swarms at the Balleny Islands, a Southern Ocean archipelago, are three times more numerous than in the adjacent open ocean, and are also denser and more compact. Around the islands, humpback whales (Megaptera novaeangliae) aggregate in areas of high productivity, medium krill density and waters greater than 350m deep. Two chapters of this thesis required manual processing of active acoustics data for detecting krill, which is time consuming and suffers from a lack of reproducibility. To automate this process, I developed an R package which drastically reduces processing time and is useful for any scientists using acoustic data. This thesis fills knowledge gaps about the mechanisms structuring the distribution of animals in the Southern Ocean and the statistical methods and software library developed are applicable to many other problems arising in complex environments.

description: Lithium abundance A(Li) and surface rotation are good diagnostic tools to probe the internal mixing and angular momentum transfer in stars. We explore the relation between surface rotation, A(Li) and age in a sample of seismic solar-analogue (SA) stars and study their possible binary nature. We select a sample of 18 SA observed by the NASA Kepler satellite for an in-depth analysis. Their seismic properties and surface rotation are well constrained from previous studies. About 53 hours of high-resolution spectroscopy were obtained to derive fundamental parameters and A(Li). These values were combined and confronted with seismic masses, radii and ages, as well as surface rotation periods. We identify a total of 6 binary systems. A well-defined relation between A(Li) and rotation was obtained. With models constrained by the characterisation of the individual mode frequencies for single stars, we identify a sequence of three SA with similar mass (~1.1Mo) and stellar ages ranging between 1 to 9 Gyr. Within the realistic estimate of ~7% for the mass uncertainty, we find a good agreement between the measured A(Li) and the predicted A(Li) evolution from a grid of models calculated with the Toulouse-Geneva stellar evolution code, which includes rotational internal mixing, calibrated to reproduce solar chemical properties. We present A(Li) for a consistent spectroscopic survey of SA with a mass of 1.00+/-0.15Mo, and characterised through asteroseismology and surface rotation rates based on Kepler observations. The correlation between A(Li) and P_rot supports the gyrochronological concept for stars younger than the Sun. The consensus between measured A(Li) for solar analogues with model grids, calibrated onto the Sun's chemical properties suggests that these targets share the same internal physics. In this light, the solar Li and rotation rate appear to be normal for a star like the Sun.

description: I revisit the exactly solvable Kipnis--Marchioro--Presutti model of heat conduction [J. Stat. Phys. 27 65 (1982)] and describe, for one-dimensional systems of arbitrary sizes whose ends are in contact with thermal baths at different temperatures, a systematic characterization of their non-equilibrium stationary states. These arguments avoid resorting to the analysis of a dual process and yield a straightforward derivation of Fourier's law, as well as higher-order static correlations, such as the covariant matrix. The transposition of these results to families of gradient models generalizing the KMP model is established and specific cases are examined.

Syria in the mirror: the politics of belonging to Syria from Syrian diasporas in Armenia and Australia

description: With the escalation of the conflict in Syria, since 2011, religious and ethnic groups have been increasingly politicised on the basis of identity. By studying Syrian immigrant communities in Armenia and Australia, this thesis explores Syrian diasporic transnationalism, testing how politicisation of identities in Syria permeate and condition what being Syrian means in exile. The focus is on the relationship between formulations of Syrian identity at the political level, before and after the outbreak of the conflict, and those of diasporic Syrian-ness. It is argued that Syria represents a case in which communal disunity is used to equate to political dissent, and where mobilisation around religious and/or ethnic identity is a result of social, political and economic disadvantage in periods of political crisis. The Syrian diasporas in the two countries chosen for the case studies, Armenia and Australia, give shape to a simplified reproduction of the politics of belonging at stake in the Syrian homeland. This thesis contributes new empirical knowledge about the political dimension of multi-layered Syrian identity. The analysis of Syrian diasporic political identity draws on interviews with Syrian-born representatives of Syrian immigrant associations, and 84 interview-based surveys with representatives, members, and independent Syrian respondents. What emerges from an integration of empirical results, theories and secondary sources is that with the sectarianisation of the conflict, the explicit use of ethno-religious identity in political debates has a social impact on diaspora. The nature of the influence is mixed: it has led both to divisions amongst Syrian To frame the complexity and ambiguity of Syrian identity re-constructions, this thesis adopts a post-structuralist constructivist approach, which does not see group attachments and national cohesion as intrinsically dichotomous. On the contrary, this study demonstrates the need to understand under what circumstances the sub-loyalties can provide a solid basis for national cohesion. The results can help evaluate the effects of national crises of identity away from the state-centred perspective that has dominated Syrian studies.

description: Multi-frequency, multi-epoch ATCA observations of a sample of AGN resulted in the identification of 9 new candidate Giga-hertz Peaked Spectrum (GPS) sources. Here we present Long Baseline Array observations at 4.8 GHz of the four candidates with no previously published VLBI image, and consider these together with previously published VLBI images of the other five sources. We find core-jet or compact double morphologies dominate, with further observations required to distinguish between these two possibilities for some sources. One of the nine candidates, PKS 1831-711, displays appreciable variability, suggesting its GPS spectrum is more ephemeral in nature. We focus in particular on the apparent relationship between a narrow spectral width and "compact double" parsec-scale morphology, finding further examples, but also exceptions to this trend. An examination of the VLBI morphologies high-redshift (z>3) sub-class of GPS sources suggests that core-jet morphologies predominate in this class.

description: In this paper we use the quantization of fields based on Geometric Langlands Correspondence \cite{diep1} to realize the automorphic representations of some concrete series of groups: for the affine Heisenberg (loop) groups it is reduced to the construction of the affine Kac-Moody representation by the Weyl relations in Fock spaces. For the solvable and nilpotent groups following the construction we show that it is the result of applying the constructions of irreducible unitary representation via the geometric quantization and the construction of positive energy representations and finally, for the semi-simple or reductive Lie groups, using the Geometric Langlands Correspondence, we show that a repeated application of the construction give all the automorphic representations of reductive Lie groups: first we show that every representation of the fundamental group of Riemann surface into the dual Langlands groups ${}^LG$ of $G$ corresponds to a representation of the fundamental group of the surface into the reductive group $G$, what is corresponding to a quantum inducing bundle of the geometric quantization of finite dimensional reductive Lie groups and then apply the construction of positive energy representation of loop groups.
