description: We analyze the cosmological simulations performed in the recent work of Greif et al. (2012), which followed the early growth and merger history of Pop III stars while resolving scales as small as 0.05 R_sol. This is the first set of cosmological simulations to self-consistently resolve the rotation and internal structure of Pop III protostars. We find that Pop III stars form under significant rotational support which is maintained for the duration of the simulations. The protostellar surfaces spin from ~50% to nearly 100% of Keplerian rotational velocity. These rotation rates persist after experiencing multiple stellar merger events. In the brief time period simulated (~ 10 yr), the protostars show little indication of convective instability, and their properties furthermore show little correlation with the properties of their host minihaloes. If Pop III protostars within this range of environments generally form with high degrees of rotational support, and if this rotational support is maintained for a sufficient amount of time, this has a number of crucial implications for Pop III evolution and nucleosynthesis, as well as the possibility for Pop III pair-instability supernovae, and the question of whether the first stars produced gamma-ray bursts.

description: The National Oceanic and Atmospheric Administration has developed a tsunami forecast model for Newport, Oregon, as part of an effort to provide tsunami forecasts for United States coastal communities. The forecast model is a set of nested grids constructed by incrementally subsampling and smoothing a reference high-resolution digital elevation model. During this process, forecast model results were monitored for deviations from those computed with the more accurate, higher-resolution model. Validation and stability testing of the tsunami forecast model developed for this economically important and populous coastal community was conducted to ensure model performance and robustness across a suite of scenarios. A total of 11 historical tsunami events and 19 synthetically generated mega-tsunami (Mw 9.3) events around the Pacific basin were used for validation and stability testing of the Newport forecast model. Validation results show that model output track observed data within an expected accuracy tolerance, thus providing a quantitative estimate of the tsunami time series, inundation, and runup at Newport for tested events. In addition to robustness, reproducibility of results was verified by comparing 2009 development results with those attained during end-to-end operational system testing performed in 2013. The differences noted in this report are attributed to the Method of Splitting Tsunami numerical code updates made after the Newport model was developed (2004) and updated (2009). Of greatest significance, 2013 test results more accurately compare with observations during the 2011 Tohoku tsunami than the earlier development results. Overall, validation results combined with benchmarking show that the forecast model developed for Newport consistently generates 4 hr of tsunami simulation in significantly less than 10 min of CPU time without compromising forecast results for all scenarios tested.

description: The rapid and widespread adoption of Deep Neural Networks (DNNs) has called for ways to test their behaviour, and many testing approaches have successfully revealed misbehaviour of DNNs. However, it is relatively unclear what one can do to correct such behaviour after revelation, as retraining involves costly data collection and does not guarantee to fix the underlying issue. This paper introduces Arachne, a novel program repair technique for DNNs, which directly repairs DNNs using their input-output pairs as a specification. Arachne localises neural weights on which it can generate effective patches and uses Differential Evolution to optimise the localised weights and correct the misbehaviour. An empirical study using different benchmarks shows that Arachne can fix specific misclassifications of a DNN without reducing general accuracy significantly. On average, patches generated by Arachne generalise to 61.3% of unseen misbehaviour, whereas those by a state-of-the-art DNN repair technique generalise only to 10.2% and sometimes to none while taking tens of times more than Arachne. We also show that Arachne can address fairness issues by debiasing a gender classification model. Finally, we successfully apply Arachne to a text sentiment model to show that it generalises beyond Convolutional Neural Networks.

description: A polynomial is real-rooted if all of its roots are real. For every polynomial $f(t) \in {\mathbf R}[t]$, the Hermite-Sylvester theorem associates a quadratic form $Φ_2$ such that $f(t)$ is real-rooted if and only if $Φ_2$ is positive semidefinite. In this note, for every positive integer $m$, an $2m$-adic form $Φ_{2m}$ is constructed such that $f(t)$ is real-rooted if and only if $Φ_{2m}$ is positive semidefinite for some $m$ if and only if $Φ_{2m}(x_1,\ldots, x_n)$ is positive semidefinite for all $m$.

description: "This study examines staff perceptions of the implementation of an Enterprise Resource Planning system (ERPs) in three Australian universities. It considers the growing body of literature on the issues impacting on effective and efficacious Enterprise Resource Planning (ERP) implementations in organisations including the most recent literature on ERPs in the higher education sector. This literature identifies a number of issues that it is argued, translates from the corporate sector to the higher education sector including a number that require additional focus in this sector. It is proposed in this dissertation that effective and efficacious implementations in Australian universities require particular consideration of organisational influences related to their context and the perceptions of the users of the systems. Case study methodology was used to examine the staff perceptions of the management of ERP implementations in universities. This involved undertaking case studies in three Australian universities in the process of implementing ERP systems. The first phase of the study obtained data through a series of focus groups at one university to explore staff perceptions of the efficacy of the ERP implementation at their university. This data and the relevant literature served as a framework for the development of the research process in the second phase of the study. This phase involved conducting a series of interviews with staff that enabled the researcher to undertake a more detailed exploration of the staff perceptions of influences affecting ERP system implementations at three Australian universities. The research study identifies the influences impacting on the outcomes of these implementations of ERPs in the three Australian universities and forms the basis for the development of guidelines for the effective and efficacious management of ERP implementations in Australian universities. This set of guidelines for the management of implementations of ERPs in Australian universities is an outcome that can have applicability for the higher education sector generally." --abstract.

description: Beyond the simplest case of bipartite qubits, the composite Hilbert space of multipartite systems is largely unexplored. In order to explore such systems, it is important to derive analytic expressions for parameters which characterize the system's state space. Two such parameters are the degree of genuine multipartite entanglement and the degree of mixedness of the system's state. We explore these two parameters for an N-qubit system whose density matrix has an X form. We derive the class of states that has the maximum amount of genuine multipartite entanglement for a given amount of mixedness. We compare our results with the existing results for the N=2 case. The critical amount of mixedness above which no N-qubit X-state possesses genuine multipartite entanglement is derived. It is found that as N increases, states with higher mixedness can still be entangled.

description: Here we present datasets provided by a SCINDA GNSS receiver installed in the Lisbon airport area from November of 2014 to July of 2019. The installed equipment is a NovAtel EURO4 with a JAVAD Choke-Ring antenna. The data are in an archived format and include the general messages on quality of records (*.msg), RANGE files (*.rng), raw observables as the signal-to-noise (S/N) ratios, pseudoranges and phases (*.obs), receiver position information (*.psn), ionosphere scintillations monitor (ISMRB; *.ism) and ionospheric parameters: total electron content (TEC), rate of change of TEC index (ROTI), and the scintillation index S4 (*.scn). The presented data cover the full 2015 year. The raw data are of 1-minute resolution and available for each of the receiver-satellite pairs. The processing and the analysis of the ionosphere scintillation datasets can be done using a specific "SCINDA-Iono" toolbox for the MATLAB developed by T. Barlyaeva (2019) and available online via MathWorks File Exchange system. The toolbox calculates 1-hour means for ionospheric parameters for each of the available receiver-satellite pairs and averaged over all available satellites during the analyzed hour. Here we present the processed data for the following months in 2015: March, June, October, and December. The months were selected as containing most significant geomagnetic events of 2015. The 1-hour means for other months can be obtained from the raw data using the aforementioned toolbox. The provided datasets are interesting for the GNSS and ionosphere based scientific communities.

Structural Violence and The Socio-Economic Rights of British Afro-Caribbean Subjects in Andrea Levy's Two Novels

Year: 2023
Subjects: Afro-Caribbean, Immigrants, Structural Violence, Socio-Economic Rights, Historical Experience.

description: Abstract
Caribbean literature has generated literary productions that border on history and identity. Many of these studies view Caribbean history both as traumatic and ignoble. This history is believed to predispose the Caribbean subjects to quest for identity or perpetual search for their root. However, sufficient critical attention has not been paid to the detrimental effects of structural violence that undermine the socio-economic rights of the descendants of the Afro-Caribbean immigrants in England, a fact which complicates their sense of self and reinvigorates their search for psychic wholeness. This study, therefore, focuses on the reality of structural violence and its effects on the identity of the British Afro-Caribbean subjects. Andrea Levy, a second-generation Afro-Caribbean British writer has continued in the tradition of the Caribbean art of commitment. She, therefore, through the characters of Faith, Gilbert and Hortense, among others, whose fight to assert their black British identity leads to some kind of complications, demonstrates how the British Afro-Caibbean subjects are shortchanged in the socio-economic sphere because of their race. These Afro-Caribbean immigrants in Britain and their descendants face frustrations as they encounter the reality of 'institutionalised' structural violence which denies them their socio-economic rights as British citizens. Their belief that they are an integral part of British cultural mainstream is therefore unrealisable, hence, they are left as second-class or marginalised citizens whose socio-economic rights are deliberately constricted.

description: Using ultrafast extreme ultraviolet pulses, we performed a direct measurement of the relaxation dynamics of neutral superexcited states corresponding to the nlσ_g(c^4Σ_u^-) Rydberg series of O_2. An XUV attosecond pulse train was used to create a temporally localized Rydberg wavepacket and the ensuing electronic and nuclear dynamics were probed using a time-delayed femtosecond near-infrared pulse. We investigated the competing predissociation and autoionization mechanisms for superexcited molecules and found that autoionization is dominant for the low n Rydberg states. We measured an autoionization lifetime of 92+/-6 fs and 180+/-10 fs for (5s,4d)σ_g and (6s,5d)σ_g Rydberg state groups respectively. We determine that the disputed neutral dissociation lifetime for the ν=0 vibrational level of the Rydberg series is 1100+/-100fs.

A cross-product free Jacobi-Davidson type method for computing a partial generalized singular value decomposition (GSVD) of a large matrix pair

description: A Cross-Product Free (CPF) Jacobi-Davidson (JD) type method is proposed to compute a partial generalized singular value decomposition (GSVD) of a large regular matrix pair $(A,B)$. It implicitly solves the mathematically equivalent generalized eigenvalue problem of $(A^TA,B^TB)$ but does not explicitly form the cross-product matrices and thus avoids the possible accuracy loss of the computed generalized singular values and generalized singular vectors. The method is an inner-outer iteration method, where the expansion of the right searching subspace forms the inner iterations that approximately solve the correction equations involved and the outer iterations extract approximate GSVD components with respect to the subspaces. Some convergence results are established for the inner and outer iterations, based on some of which practical stopping criteria are designed for the inner iterations. A thick-restart CPF-JDGSVD algorithm with deflation is developed to compute several GSVD components. Numerical experiments illustrate the efficiency of the algorithm.

How to exchange data between DB Systems on Early Humans. A case study based on the SFB 806 DB and the ROCEEH ROAD system
Creators: name: Willmes, Christian
name: Bareth, Georg
Publisher: name: CRC806-Database
Year: 2015

description: In the recent past data base systems providing information on early humans and their environment are becoming more and more important and increase rapidly in number. However, this increase in different DB systems is concomitant with an increasing redundancy in the digital information stored in these database systems. Therefore, in this study we explore ways to reduce redundancies due to multiple storage of data and, hence, we show solutions to minimize the requirements to store and manage digital information in the prehistory and paleoenvironment domains.

The example is based on the database systems of the DFG financed SFB 806: “Our Way to Europe” and the Heidelberg Academy of Sciences and Humanities project entitled: “The Role Of Culture in Early Expansion of Humans (ROCEEH). We focus especially on the spatial data available in both systems as well as on the environmental information. Therefore, we examine and test exchange interfaces based on Spatial Data Infrastructure technology (OGC Standards) and metadata/schema mappings.

The poster presents currently implemented interfaces of both data base systems in terms of their main commonalities and differences. Based on this overview, we discuss ways of direct links between the DB systems. Moreover, we identify procedures that need to be developed in the future to integrate and exchange data between both systems.

We show that DB-linking activities based on the OGC standards yield valuable results and lead to a more efficient, sustainable management of these DB systems providing added values for the related research groups.

description: We estimate the resource requirements for the quantum simulation of the ground state energy of the one dimensional quantum transverse Ising model (TIM), based on the surface code implementation of a fault tolerant quantum computer. The surface code approach has one of the highest known tolerable error rates (1%) which makes it currently one of the most practical quantum computing schemes. Compared to results of the same model using the concatenated Steane code, the current results indicate that the simulation time is comparable but the number of physical qubits for the surface code is 2-3 orders of magnitude larger than that of the concatenation code. Considering that the error threshold requirements of the surface code is four orders of magnitude higher than the concatenation code, building a quantum computer with a surface code implementation appears more promising given current physical hardware capabilities.

description: This paper studies various properties of amplitudes in 3d super Yang Mills theory. First we explain how to obtain the amplitudes of 3d super Yang Mills theories from 4d super Yang Mills theories and obtain their helicity structure. Next, we use a 3d BFCW recursion relation to show that the tree amplitudes and loop integrands of maximal 3d super Yang Mills have dual conformal covariance (although not invariance, so that the amplitudes themselves are not dual conformal). Finally, we argue that the one-loop amplitudes of maximal 3d super Yang-Mills can be reduced to scalar box diagrams and evaluate these diagrams using dimensional regularization. We find that the one-loop MHV amplitudes vanish and the one-loop non-MHV amplitudes are finite.

Evaluation and modelling performance of capping layer in rail track substructure
Creators: name: Radampola, Senanie
Publisher: name: CQUniversity
Year: 2023
Subjects: classificationCode: 400508
subject: Infrastructure engineering and asset management

description: "In the design of rail track structures where the subgrade cannot achieve the desired capacity, enabling the required standard of track geometry to be maintained for the speed, axle load and tonnage to be hauled, a capping layer of granular material is placed between the natural ground or the embankment fill material and the ballast to protect the underlying weaker layers. In spite of the important role played by the capping layer, very little research has been carried out on its performance. The current practice of design of the capping layer, therefore, is based on working stress philosophy where reduced levels of stresses are assumed not to degrade the subgrade. Even on tracks containing a thick ballast layer that ensures allowable levels of working stress the subgrade has been found to have permanently deformed. Design of capping layers based on plastic deformation, therefore, appears appropriate. This thesis aims at determining the load levels that cause detrimental plastic deformation in the capping layer. The suite of material properties that characterise plastic deformations of capping layer is neither readily available nor easily determined. This thesis proposes a cheaper method of evaluating a range of capping layer material properties using penetration tests on specimens contained in California Bearing Ratio (CBR) test moulds coupled with a finite element modelling based back calculation technique. The suite of material properties thus determined are used for the simulation of the behaviour of capping layers under the boundary and loading conditions similar to those in practice. The predicted results are validated using laboratory experiments on large size capping layer specimens." -- abstract

description: This report documents the reference and forecast model development for Point Reyes, California, and its vicinity, comprising much of western Marin County. The Point Reyes headland juts out into the Pacific Ocean and it s lighthouse is a prominent navigation landmark northwest of the entrance to San Francisco Bay. A tide gauge within Drakes Bay, in the lee of the headland, provides observations for model validation from numerous historical tsunamis. While much of the study region lies within a National Seashore area, limiting the population and waterfront in frastructure, there are a number of nearby communities exposed to tsunami impact. Beaches and other natural amenities and the mild climate foster extensive recreational use, and there is a clear need for emergency preparedness. This report addresses the tsunami aspects of the natural hazard spectrum.
The predominance of women in public relations

description: Examines the reasons for the growth in numbers of women and the numerical decline of men within public relations in Perth, Western Australia and also the future trends within the profession for both women and men and what an imbalance may mean.. " As (almost) everyone in the Australian public relations industry knows, there are more women than men. On average, the numbers in Perth (and nationally) favour women by slightly more than three to one. However, the figures are alarmingly high, and, according to Australian Bureau of Statistics figures, make PR one of the most female-intensive industries in Australia. This growing imbalance may have long-term effects which have yet to be identified. This thesis, however, seeks to consider the reasons for this situation. The research aims to: 1. Examine the reasons for the growth in numbers of women and numerical decline of men within public relations in Perth, Western Australia, by considering the development of public relations and how it has impacted on the composition of the profession. 2. Examine future trends within the profession for both women and men and what an imbalance may mean. Patterns in the data clearly show that women outnumber men by almost 3:1, with statistics consistent across all groups surveyed. For example, in government PR practitioners are 71 per cent female, while in private practice (both nationally and in WA) it is 74 per cent. In WA charities the figure is 75 per cent. At the universities it varies between 72 and 87 per cent. This study examines the reason for the imbalance and whether an imbalance is good. Whether the industry (professional bodies, educators, students and practitioners) is concerned is up to it. This work provides the first study of the gender composition of the industry in Australia. As such, it should be a valuable tool in a number of areas. Like many initial studies, it raises just as many questions as answers, and it provides pathways for future study. It should lead to a wider examination of further issues. For example: does the predominance of women in PR in university courses cause concern among male students, perhaps leading them to question their continued participation? Do male students wonder whether the female dominance of PR courses will lessen their chances of employment. And what do practitioners think of an industry that is feminine?" -- abstract

description: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is caused by mutations in one of two genes, PKD1 or PKD2, which result in accumulation of cysts in the kidneys. The objective of this study was to verify the existence of possible associations between variants in cytokine genes and cytokine receptors for positions IL1A-889 (rs1800587), IL1B-511, +3962 (rs16944, rs1143634), IL1R1970 (rs2234650), IL1RA11100 (rs315952), IL4RA+1902 (rs1801275), IL12-1188 (rs3212227), IFNG+874 (rs2430561), TGFB1codon 10, codon 25 (rs1982073, rs1800471), TNF-308, -238 (rs1800629, rs361525) IL2-330, +166 (rs2069762, rs2069763), IL4-1098, -590, -33 (rs2243248, rs2243250, rs2070874), IL6-174, nt565 (rs1800795, rs1800797) and IL10-1082, -819, -592 (rs1800896, rs1800871, rs1800872) and ADPKD. The sample included 60 patients with ADPKD and 113 individuals without the disease, not related. Genotyping of variants in genes of cytokines and cytokine receptors was performed by PCR-SSP method, with the genotyping kit (Cytokine Genotyping Kit, Invitrogen ™). Of the total subjects, men frequency for cases and controls was 55% (33/60) and 63% (71/113), respectively. The samples consisted of 76.7% Caucasian, 20% African Americans and 3.3% of Asians to the group of cases, and 59.3% Caucasian, 34.5% of African Americans and 6.2% of Asians to the group of controls. Comparisons between groups showed statistically significant associations for haplotypes, genotypes and alleles. There was influence on susceptibility or resistance to the predisposition of ADPKD the following variants in genes of proinflammatory cytokines: TNF-308, -238 (GG/GG [OR = 0.44]), -238 (G/G [OR = 0.35], G/A [OR = 2.84], G [OR = 0.38] and A [OR = 2.62]) and IL2-330, +166 (GG/GG [OR = 4.93]), -330 (G/G [OR = 2.56]) and anti-inflammatory TGFB1códon 10 (C/C [OR = 2.22] and C [OR = 1.66]) and IL4-1098, -590, -33 (TCC/GCC [OR = 2.14]), -1098 (T/G [OR = 2.31]). The results showed that SNPs in cytokine genes are possible determinants in predisposition to ADPKD. This evidence may contribute to the knowledge of etiopatogenicity of ADPKD, to provide new and more accurate genetic markers associated with predisposition to disease, and the development of procedures that can minimize their impacts (social and individual) through strategies in the prevention, diagnosis, genetic counseling and treatment.

description: Controlling the momentum of carriers in semiconductors, known as valley polarization, is a new resource for optoelectronics and information technologies. Materials exhibiting high polarization are needed for valley-based devices. Few-layer WS$_2$ shows a remarkable spin-valley polarization above 90%, even at room temperature. In stark contrast, polarization is absent for few-layer WSe$_2$ despite the expected material similarities. Here, we explain the origin of valley polarization in both materials based on the interplay between two indirect optical transitions. We show that the relative energy minima at the $Λ$- and K-valleys in the conduction band determine the spin-valley polarization of the direct K-K transition. Polarization appears as the energy of the K-valley rises above the $Λ$-valley as a function of temperature and number of layers. Our results advance the understanding of the high spin-valley polarization in WS$_2$. This insight will impact the design of both passive and tunable valleytronic devices operating at room temperature.

description: We study electronic transport in junctions consisting of a superconductor electrode and two ferromagnet (F) leads in which crossed Andreev reflections (CAR) and elastic cotunnelings are accommodated. We model the system using an extended Blonder-Tinkham-Klapwijk treatment with a key modification that accounts for spin-dependent interfacial barriers (SDIB). We compute current-voltage relations as a function of parameters characterizing the SDIB, magnetization in the F leads, geometry of the junction, and temperature. Our results reveal a rich range of significantly altered physics due to a combination of interfering spin-dependent scattering processes and population imbalance in the ferromagnets, such as a significant enhancement in CAR current and a sign change in the relative difference between resistance of two cases having a antiparallel or parallel alignment of the magnetization in the F leads, respectively. Our model accounts for the surprising experimental findings of positive relative resistance by M. Colci et al. [Phys. Rev. B 85, 180512(R) (2012)] as well as previously measured negative relative resistance results, both within sufficiently large parameter regions.

However, these architectures cannot easily keep up with some of the challenges introduced by recent trends, such as the growth in the number of IoT devices, increasing awareness about the privacy and security implications of extensive data collection, and the rise of graph-structured data and Graph Representation Learning. Systems based on either direct data collection or Federated Learning contain centralized, privileged systems that may act as scalability bottlenecks and dangerous single points of failure, while requiring users to trust the privacy protections and security practices in place. The combination of these issues ultimately leads to data waste, as opportunities to extract insights from available data are missed and thus the full societal benefits of advanced data analytics and ML are not realized. In this thesis, we argue for a paradigm shift towards a completely decentralized and trustless architecture for privacy-aware Graph Representation Learning, which employs Gossip Learning and other gossip-based peer-to-peer techniques to achieve high levels of scalability and resilience while reducing the risk of privacy leaks. We then identify and pursue three key research directions necessary to achieve our vision: lifting unrealistic assumptions on Gossip Learning, identifying and developing specific use cases that are enabled or improved by gossip-based decentralization, and overcoming the obstacles to the deployment of decentralized training and inference for Graph Representation Learning models. Based on these key directions, our contributions are as follows. First, we analyze the robustness of Gossip Learning when several unrealistic but often assumed conditions are lifted. Then, we exploit Gossip Learning and gossip-based peer-to-peer protocols more in general across three use cases: the collaborative training of differentially-private Naive Bayes classifiers across organizations holding sensitive user data; the construction of decentralized, privacy-preserving data marketplaces; and the development and decentralization of early-stage IoT botnet detection systems based on Graph Representation Learning. Finally, we introduce a general framework for the fully-decentralized training of Graph Neural Networks, overcoming the typical requirement of these models to access non-local information during training and inference. The combination of these contributions removes major roadblocks towards decentralized graph learning, and also opens a new research direction aimed at further developing and optimizing the fully-decentralized training of Graph Representation Learning models.

description: A coarse-grained description for the formation and evaporation of a black hole is given within the framework of a unitary theory of quantum gravity preserving locality, without dropping the information that manifests as macroscopic properties of the state at late times. The resulting picture depends strongly on the reference frame one chooses to describe the process. In one description based on a reference frame in which the reference point stays outside the black hole horizon for sufficiently long time, a late black hole state becomes a superposition of black holes in different locations and with different spins, even if the back hole is formed from collapsing matter that had a well-defined classical configuration with no angular momentum. The information about the initial state is partly encoded in relative coefficients---especially phases---of the terms representing macroscopically different geometries. In another description in which the reference point enters into the black hole horizon at late times, an S-matrix description in the asymptotically Minkowski spacetime is not applicable, but it sill allows for an "S-matrix" description in the full quantum gravitational Hilbert space including singularity states. Relations between different descriptions are given by unitary transformations acting on the full Hilbert space, and they in general involve superpositions of "distant" and "infalling" descriptions. Despite the intrinsically quantum mechanical nature of the black hole state, measurements performed by a classical physical observer are consistent with those implied by general relativity. In particular, the recently-considered firewall phenomenon can occur only for an exponentially fine-tuned (and intrinsically quantum mechanical) initial state, analogous to an entropy decreasing process in a system with large degrees of freedom.

description: The notion of Queensland as a Smart State is the Queensland Beattie Governments response to global conditions that require a new type of worker and citizen for a new knowledge economy. The role of education in the success of the Smart State is clearly outlined in the Queensland Governments vision statements and policies, identifying teachers as a key factor in the production of this new type of worker and citizen. In this study I explore the relationship between Queenslands Smart State policy and the daily practices of teachers as they are implicated in the building of a Smart State. The study takes place during what is unquestionably the largest and most comprehensive reform effort to be imposed on Queensland schools and teachers, under the auspices of a Smart State. The research includes policy analysis of two key Smart State documents, and fieldwork involving semi-structured interviews, observations and artefact collection of the work of two primary school teachers. Using Faircloughs theories regarding the relationship between discourse and social change, it is possible to show how changes occurring in contemporary organisations are related to changes in discourse, in particular, those surrounding the discourses of a knowledge economy or globalisation. The Smart State is conceptualised in this study as regimes of discourses that may produce new practices and new ways of acting and being (Fairclough, 2001a). The interdiscursive, linguistic and semiotic strategies used in Smart State policy are analysed to show how this discourse is emerging into a hegemonic position, while identifying the dominant discourses reiterated in the policy as necessary skills for a new type of worker. These discourses are mapped onto those identified through the fieldwork of teachers daily work practices to determine if Smart State discourses are becoming apparent in teachers work. This study is significant because it makes visible the current relationship between the discourses of the Smart State and teachers daily work. In this current climate of rapid change and economic survival it is important that the operationalization of a Smart State can be attributed to teachers work as new ways of acting and interacting become a part of their daily practices.

description: A set $A$ of nonnegative integers is an asymptotic basis of order $h$ if every sufficiently large integer can be represented as the sum of $h$ not necessarily distinct elements of $A$. The asymptotic basis $A$ is minimal if removing any element of $A$ destroys every representation of infinitely many integers, and so $A\setminus \{a\}$ is not an asymptotic basis of order $h$ for all $a\in A$. In this paper, a new class of minimal asymptotic bases is constructed.

Lepton Number Violating Electron Recoils in a $U(1)_{B-L}$ Model with Non-Standard Interactions

description: We propose an $SU(3)_C\times SU(2)_L\times U(1)_{Y}\times U(1)_{B-L}$ model, in which the neutrino masses and mixings can be generated via Type-I seesaw mechanism after $U(1)_{B-L}$ breaking. A light mediator emerges and enables non-standard interaction that violates the lepton number. We show that the non-standard neutrino interaction emerges in this model, and it can lead to low energy recoil events with the solar neutrino flux. Analyses are performed with the keV range electron recoil events at recent direct detection experiments, including XENON1T, PANDAX and XENONnT. Recent direct detection observations lead to upper bound on the combined coupling strength to electron and neutrino to $\sqrt{y'_νy_e} < 0.5 \times 10^{-6}$.

description: In the new digital age, information is available in large quantities. Since information consumes primarily the attention of its recipients, the scarcity of attention is becoming the main limiting factor. In this study, we investigate the impact of advertisement pressure on a cultural market where consumers have a limited attention capacity. A model of competition for attention is developed and investigated analytically and by simulation. Advertisement is found to be much more effective when attention capacity of agents is extremely scarce. We have observed that the market share of the advertised item improves if dummy items are introduced to the market while the strength of the advertisement is kept constant.

description: The near-horizon field B of an old black hole is maximally entangled with the early Hawking radiation R, by unitarity of the S-matrix. But B must be maximally entangled with the black hole interior A, by the equivalence principle. Causal patch complementarity fails to reconcile these conflicting requirements. The system B can be probed by a freely falling observer while there is still time to turn around and remain outside the black hole. Therefore, the entangled state of the BR system is dictated by unitarity even in the infalling patch. If, by monogamy of entanglement, B is not entangled with A, the horizon is replaced by a singularity or "firewall". To illustrate the radical nature of the ideas that are needed, I briefly discuss two approaches for avoiding a firewall: the identification of A with a subsystem of R; and a combination of patch complementarity with the Horowitz-Maldacena final-state proposal.
