title: Eyes of identification : challenges and opportunities in leveraging highly visible, multiple-level histories
Creators: name: Rosser, Debra
name: Swain, Shurlee
Publisher: name: Strathprints - University of Strathclyde
Year: 2013

description: Histories of out of home 'care' have traditionally fallen into four categories: in-house productions, commissioned histories; academic studies and survivor narratives. Each of these is problematic. A more inclusive approach, which encourages a close relationship between historian and those who lived the experience, is offered through projects arising from Australian government enquiries into indigenous, migrant and Australian-born children in care. These projects challenge historians on two main fronts: They defy historians' 'scholarly distance' and require them to embrace alternative, often competing and personally confronting, histories as they seek to incorporate care leavers' voices in published history. A greater challenge, though, is for historians to find effective ways to intersect public history with public policy so that the undesirable legacies of the past do not recur in the futures of the children who are in out of home care today.

description: Two related but differentially expressed potential membrane proteins of Epstein-Barr virus are encoded by the same reading frame in the EcoRI D het region of the viral genome. Potential antigenic sites in the amino acid sequence of these proteins were selected by computer-aided prediction of the secondary structure and two oligopeptides corresponding to regions located in different parts of the proteins were synthesized chemically. Rabbit antisera to these peptides were used for immunoprecipitation of the native viral proteins from Epstein-Barr virus-positive cell lines from various sources. Both predicted membrane proteins could be precipitated from cell lines that had been transformed in vitro with EBV or from cell lines derived from infectious mononucleosis patients. In cell lines established from Burkitt lymphoma, only the smaller polypeptide, which lacks 138 amino acids from the amino terminus, could be identified. Using the synthetic peptides as antigens in ELISA, we detected elevated antibody titers in sera from patients with infectious mononucleosis and nasopharyngeal carcinoma.

description: In graphene growth, island symmetry can become lower than the intrinsic symmetries of both graphene and the substrate. First-principles calculations and Monte Carlo modeling explain the shapes observed in our experiments and earlier studies for various metal surface symmetries. For equilibrium shape, edge energy variations $δE$ manifest in distorted hexagons with different ground-state edge structures. In growth or nucleation, energy variation enters exponentially as $\sim e^{δE / k_{B} T}$, strongly amplifying the symmetry breaking, up to completely changing the shapes to triangular, ribbon-like, or rhombic.

description: We propose a fast method to determine the local curvature in two-dimensional (2D) systems with arbitrary shape. The curvature information, combined with elastic constants obtained for a planar system, provides an accurate estimate of the local stability in the framework of continuum elasticity theory. Relative stabilities of graphitic structures including fullerenes, nanotubes and schwarzites, as well as phosphorene nanotubes, calculated using this approach, agree closely with ab initio density functional calculations. The continuum elasticity approach can be applied to all 2D structures and is particularly attractive in complex systems with known structure, where the quality of parameterized force fields has not been established.

description: The pseudogap regime of high-temperature cuprates harbours diverse manifestations of electronic ordering whose exact nature and universality remain debated. Here, we show that the short-ranged charge order recently reported in the normal state of YBa2Cu3Oy corresponds to a truly static modulation of the charge density. We also show that this modulation impacts on most electronic properties, that it appears jointly with intra-unit-cell nematic, but not magnetic, order, and that it exhibits differences with the charge density wave observed at lower temperatures in high magnetic fields. These observations prove mostly universal, they place new constraints on the origin of the charge density wave and they reveal that the charge modulation is pinned by native defects. Similarities with results in layered metals such as NbSe2, in which defects nucleate halos of incipient charge density wave at temperatures above the ordering transition, raise the possibility that order-parameter fluctuations, but no static order, would be observed in the normal state of most cuprates if disorder were absent.

description: GDart is a software verification tool for the JVM employing dynamic symbolic execution. We implemented it in modules separated by well-defined interfaces and protocols: DSE handles symbolic exploration, while SPouT performs symbolic tracing via GraalVM. Interaction with SMT-LIB is handled by the JConstraints library. We also packaged the Z3 and CVC4 SMT solvers are in the TurnKey Maven artifacts that do not require manual software installation.

 This separation of concerns and the publication of these components as open-source software at https://github.com/tudo-aqua results in highly reusable artifacts that have been successfully employed in other projects: RALib uses JConstraints to access SMT Solvers for automaton learning and the symbolic verifier GDart-LLVM was created by replacing SPout with a symbolic tracer for LLVM IR in the existing GDart tool stack.
Functional Interdependence of Anoctamins May Influence Conclusions from Overexpression Studies

description: Anoctamin 6 (ANO6, TMEM16F) is a phospholipid (PL) scramblase that moves PLs between both plasma membrane (PM) leaflets and operates as an ion channel. It plays a role in development and is essential for hemostasis, bone mineralization and immune defense. However, ANO6 has also been shown to regulate cellular Ca2+ signaling and PM compartments, thereby controlling the expression of ion channels such as CFTR. Given these pleiotropic effects, we investigated the functional interdependence of the ubiquitous ANO6 with other commonly co-expressed anoctamins. As most expression studies on anoctamins use HEK293 human embryonic kidney cells, we compared ion currents, PL scrambling and Ca2+ signals induced by the overexpression of anoctamins in HEK293 wild-type parental and ANO6-knockout cells. The data suggest that the endogenous expression of ANO6 significantly affects the results obtained from overexpressed anoctamins, particularly after increasing intracellular Ca2+. Thus, a significant interdependence of anoctamins may influence the interpretation of data obtained from the functional analysis of overexpressed anoctamins.
Distinguishing models of reionization using future radio observations of 21-cm 1-point statistics

description: We explore the impact of reionization topology on 21-cm statistics. Four reionization models are presented which emulate large ionized bubbles around over-dense regions (21CMFAST/ global-inside- out), small ionized bubbles in over-dense regions (local-inside-out), large ionized bubbles around under-dense regions (global-outside-in) and small ionized bubbles around under-dense regions (local-outside-in). We show that first-generation instruments might struggle to distinguish global models using the shape of the power spectrum alone. All instruments considered are capable of breaking this degeneracy with the variance, which is higher in outside-in models. Global models can also be distinguished at small scales from a boost in the power spectrum from a positive correlation between the density and neutral-fraction fields in outside-in models. Negative skewness is found to be unique to inside-out models and we find that pre-SKA instruments could detect this feature in maps smoothed to reduce noise errors. The early, mid and late phases of reionization imprint signatures in the brightness-temperature moments, we examine their model dependence and find pre-SKA instruments capable of exploiting these timing constraints in smoothed maps. The dimensional skewness is introduced and is shown to have stronger signatures of the early and mid-phase timing if the inside-out scenario is correct.

description: The utilization of construction and demolition waste is useful for sustainable infrastructure development and protecting the environment. In this research, the properties of self-compacting concrete produced by replacing the natural coarse aggregates (NCA) with inferior recycled coarse aggregates (RCA) were investigated. The properties of self-compacting concrete (SCC) and self-compacting mortar (SCM) with varying replacements of RCA (0, 25, 50, and 100%) in NCA were determined. The flow, strength, early shrinkage tests, and microstructure using X-ray diffraction (XRD) and a scanning electron microscope (SEM) were investigated. The fresh property results indicated that the viscosity of freshly mixed SCC increased with higher replacement levels of RCA, thus reducing flow. The compressive strength of RCA SCC was reduced up to 30% for a 100% replacement level, while the flexural strength was reduced by about 15%. The compressive strength and flexural strength of SCMs, however, increased up to 12% and 28% for 100% replacement with RCA. The mechanical strength of SCM increases with RCA because of high fine content which reduces the porosity and makes the system denser. The early age linear shrinkage increases with RCA due to its greater water absorption. The results indicate that recycled coarse aggregate can be effectively used as the replacement of NCA in SCC to produce sustainable and eco-friendly structural concrete.

description: For data publications a description as complete as possible for the data set creation is the goal. The more devices are involved the more parameters and settings have to be documented. Electronic lab documentation can support the user to reach that goal. It is more than just an Electronic Lab Notebook (ELN). It is the integration into an ecosystem of different software. By connecting all the device interfaces all the parameters and settings can be automated documented. The scientist should enter values only once e.g. parameters in some experiment control software or project information at project proposal. Everything is collect and connected by the electronic lab documentation, which can be extended by manual notes. The documentation occurs in a structured manner, which makes the publication process easier, e.g. pre-fill from the project proposal. For the data publication the published data then includes not only the data and project information, it will be extended by all meta data known to the specific data set, which is linked within the electronic lab documentation.
Nonequilibrium dynamics of the Ising model on heterogeneous networks with an arbitrary distribution of threshold noise

description: The Ising model on networks plays a fundamental role as a testing ground for understanding cooperative phenomena in complex systems. Here we solve the synchronous dynamics of the Ising model on random graphs with an arbitrary degree distribution in the high-connectivity limit. Depending on the distribution of the threshold noise that governs the microscopic dynamics, the model evolves to nonequilibrium stationary states. We obtain an exact dynamical equation for the distribution of local magnetizations, from which we find the critical line that separates the paramagnetic from the ferromagnetic phase. For random graphs with a negative binomial degree distribution, we demonstrate that the stationary critical behavior as well as the long-time critical dynamics of the first two moments of the local magnetizations depend on the distribution of the threshold noise. In particular, for an algebraic threshold noise, these critical properties are determined by the power-law tails of the distribution of thresholds. We further show that the relaxation time of the average magnetization inside each phase exhibits the standard mean-field critical scaling. The values of all critical exponents considered here are independent of the variance of the negative binomial degree distribution. Our work highlights the importance of certain details of the microscopic dynamics for the critical behavior of nonequilibrium spin systems.

Two-channel anomalous Hall effect originating from the intermixing in Mn2 CoAl/ Pd thin films

Year: 2022

description: The anomalous Hall effect (AHE) is an electronic transport phenomenon with rich physics. In thin magnetic films and multilayers, an unusual peak observed in AHE is often identified as the topological Hall effect (THE), induced by topologically nontrivial spin textures. However, it is a challenge to determine whether this unusual peak truly originates from such spin textures or is an artifact due to inhomogeneities. In this work, we systematically study the Pd thickness and temperature dependence of the Hall effect in Mn2CoAl/Pd thin films. We observe an unusual peak in the Pd thickness dependence and rule out that the origin of the peak is from the topologically nontrivial spin textures by directly imaging the magnetic domain structures. We also build a model for the AHE based on the sum of contributions from Mn2CoAl and an intermixed CoPd alloy. These materials have opposite signs of the AHE and different coercive fields, which successfully explains the thickness and temperature behaviors of the unusual peak. Our results show that the interface mixing layer can play an important role in the interpretation of the AHE in ferromagnet/heavy metal systems.

description: The presence of IgA antibody to membrane antigen (MA) of Epstein-Barr virus (EBV) was tested in sera from 48 nasopharyngeal carcinoma (NPC) patients, 40 patients with tumors other than NPC and 46 normal individuals. The sera were preabsorbed with Staphylococcus aureus (SPA) (strain no. 1800) prior to their use in the indirect immunofluorescence test. One hundred percent of the NPC patients had the IgA/MA antibody with a GMT of 1:141. In patients with tumors other than NPC or normal individuals, IgA/MA antibodies were not detectable. The IgA/MA antibodies have been demonstrated in 6 NPC patients lacking detectable antibody levels in the indirect immunofluorescence test using nonabsorbed sera. Our data indicate that preabsorbtion of sera with SPA renders the diagnostic test significantly more sensitive for the detection of the nasopharyngeal carcinoma and can be used for trials on the prognosis of patients.

description: In the general framework of Metric-Affine theories of gravity, where the metric and the connection are independent variables, we consider actions quadratic in the Ricci scalar curvature and the Holst invariant (the contraction of the Riemann curvature with the Levi-Civita antisymmetric tensor) coupled non-minimally to a scalar field. We study the profile of the equivalent effective metric theory, featuring an extra dynamical pseudoscalar degree of freedom, and show that it reduces to an effective single-field inflationary model. We analyze in detail the inflationary predictions and find that they fall within the latest observational bounds for a wide range of parameters, allowing for an increase in the tensor-to-scalar ratio. The spectral index can either decrease or increase depending on the position in parameter space.

description: In the context of varieties of representations of arbitrary quivers, possibly carrying loops, we define a generalization of Lusztig Lagrangian subvarieties. From the combinatorial study of their irreducible components arises a structure richer than the usual Kashiwara crystals. Along with the geometric study of Nakajima quiver varieties, in the same context, this yields a notion of generalized crystals, coming with a tensor product. As an application, we define the semicanonical basis of the Hopf algebra generalizing quantum groups, which was already equipped with a canonical basis. The irreducible components of the Nakajima varieties provide the family of highest weight crystals associated to dominant weights, as in the classical case.

description: The expression of the two Epstein-Barr virus (EBV) major membrane proteins gp250/350 (MA-BLLF1) on the surface of recombinant CHO clones cannot be amplified by methotrexate (MTX) selection, perhaps due to toxic effects of these membrane proteins. After removal of sequences encoding the part of the glycoproteins responsible for membrane anchorage, the gp250/350 is secreted into the medium. Following selection with MTX, this construct allows the amplification of the expression products. Besides the possible use of these proteins in protection experiments, they can also be used as antigens for diagnosis, which opens an efficient approach for control of EBV-related neoplasias by early therapy.

The validity of the method is checked by comparing with the results of rigorous QED in simple atomic potentials. We study the effects of core relaxation, polarization of the core by the E1 field, and valence-core correlations on QED, which are shown to be important in some cases. We identify several transitions for which the QED contribution exceeds the deviation between atomic theory and experiment.

description: It is known that by introducing the Yukawa coupling between the fermion and the background scalar field, a bulk spin-half fermion can be localized on general Randall-Sundrum braneworlds generated by a kinklike background scalar. However, this localization mechanism does not work anymore for Randall-Sundrum braneworlds generated by a scalar whose configuration is an even function of the extra dimension. In this paper, we present a new localization mechanism for spin-half fermions for such a class of braneworld models, in which extra dimension has the topology $S^1/Z_2$. By two examples, it is shown that the new localization mechanism produces interesting results. In the first model with the brane generated by two scalars, the zero mode of the left-handed fermion is localized on the brane and there is a mass gap between the fermion zero mode and excited KK modes. In the second model with the brane generated by a dilaton scalar, the zero mode of the left- or right-chiral fermion can be localized on the brane and there is no mass gap.

description: We study a diffuse interface model for the flow of two viscous incompressible Newtonian fluids in a bounded domain. The fluids are assumed to be macroscopically immiscible, but a partial mixing in a small interfacial region is assumed in the model. Moreover, diffusion of both components is taken into account. In contrast to previous works, we study a model for the general case that the fluids have different densities due to Lowengrub and Truskinovski [27]. This leads to an inhomogeneous Navier-Stokes system coupled to a Cahn-Hilliard system, where the density of the mixture depends on the concentration, the velocity field is no longer divergence free, and the pressure enters the equation for the chemical potential. We prove existence of unique strong solutions for the non-stationary system for sufficiently small times.

description: In continuation of [1] we study associated primes of Matlis duals of local cohomology modules (MDLCM). We combine ideas from Helmut Zöschinger on coassociated primes of arbitrary modules with results from [1], [4], [5], [6] and obtain partial answers to questions which were left open in [1]. These partial answers give further support for conjecture (¤) from [1] on the set of associated primes of MDLCMs. In addition, and also inspired by ideas from Zöschinger, we prove some non-finiteness results of local cohomology.

description: Independent isolates of human immunodeficiency virus (HIV) exhibit a striking genomic diversity, most of which is located in the viral envelope gene. Since this property of the HIV group of viruses may play an important role in the pathobiology of the virus, we analyzed the predicted amino acid sequences of the envelope proteins of seven different HIV strains, three of which represent sequential isolates from a single patient. By using a computer program that predicts the secondary protein structure and superimposes values for hydrophilicity, surface probability, and flexibility, we identified several potential antigenic epitopes in the envelope proteins of the seven different viruses. Interestingly, the majority of the predicted epitopes in the exterior envelope protein (gp120) were found in regions of high sequence variability which are interspersed with highly conserved regions among the independent viral isolates. A comparison of the sequential viral isolates revealed that changes concerning the secondary structure of the protein occurred only in regions which were predicted to be antigenic, predominantly in highly variable regions. The membrane-associated protein gp41 contains no highly variable regions; about 80% of the amino acids were found to be conserved, and only one hydrophilic area was identified as likely to be accessible to antibody recognition. These findings give insight into the secondary and possible tertiary structure of variant HIV envelope proteins and should facilitate experimental approaches directed toward the identification and fine mapping of HIV envelope proteins.

description: Using extended coherent states, an analytical exact study has been carried out for the quantum Rabi model (QRM) with two arbitrary qubits in a very concise way. The $G$-functions with $2 \times 2$ determinants are generally derived. For the same coupling constants, the simplest $G$-function, resembling that in the one-qubit QRM, can be obtained. Zeros of the $G$-function yield the whole regular spectrum. The exceptional eigenvalues, which do not belong to the zeros of the $G$ function, are obtained in the closed form. The Dark states in the case of the same coupling can be detected clearly in a continued-fraction technique. The present concise solution is conceptually clear and practically feasible to the general two-qubit QRM and therefore has many applications.

description: Molecular biology allowed considerable improvements in diagnostic procedures by production of new and more specific sonds for the detection of traces of viruses, both on the nucleic acid and protein levels, and by determining the immune response of the host to specific antigens. Improvements in sensitivity and improved correlation to the stage of viral disease are already evident from several applications and strongly suggest a broad application of these approaches.

description: These experiments identify an Epstein-Barr virus-encoded gene product, called ZEBRA (BamHI fragment Z Epstein-Barr replication activator) protein, which activates a switch between the latent and replicative life cycle of the virus. Our previous work had shown that the 2.7-kilobase-pair WZhet piece of rearranged Epstein-Barr virus DNA from a defective virus activated replication when introduced into cells with a latent genome, but it was not clear whether a protein product was required for the phenomenon. We now use deletional, site-directed, and chimeric mutagenesis, together with gene transfer, to show that a 43-kilodalton protein, encoded in the BZLF1 open reading frame of het DNA, is responsible for this process. The rearrangement in defective DNA does not contribute to the structural gene for the protein. Similar proteins with variable electrophoretic mobility (37 to 39 kilodaltons) were encoded by BamHI Z fragments from standard, nondefective Epstein-Barr virus genomes. Plasmids expressing the ZEBRA proteins from B95-8 and HR-1 viruses were less efficient at activating replication in D98/HR-1 cells than those which contained the ZEBRA gene from the defective virus. It is not yet known whether these functional differences are due to variations in expression of the plasmids or to intrinsic differences in the activity of these polymorphic polypeptides.

description: HIV-infections can be transferred by blood and blood products, semen or organ transplants. For this reason, the WHO recommended a screening of all donors of blood, semen, tissues and organs. Those who belong to high-risk groups should be excluded from donations. If this recommendation should be also applied to cialit preserved auditory aussicles, this would probably mean the end of allogeneic transplantations of middle-ear surgery which are being performed daily. Therefore, we carried out experimental examinations with HIV-infected auditory aussicles in cialit. According to our results, it can be assumed that a virus-destruction takes place via a cialit-treatment. The same applies to solvent-dried fascia as to auditory aussicles which have been preserved in the same way. Consequently, there is no objection to further application of these allogeneic transplants in respect to HIV-infections.

description: The financial system plays a pivotal role in economic activities in any country. Thus, it is vital to determine the status and assess the financial health of the financial system and take corrective policy measures continuously. The main objective of the study is to examine the effect of bank regulation on the performance of private commercial banks. The study used balanced panel model in examining the regression model and collect data from ten private commercial banks covering the period of six (6) consecutive years, 2011-2016with a total of 60 observations. To this end, the study employed a quantitative research approach by documentary analysis based on their audited financial statement. The study used panel data techniques specifically fixed effect model on the regression analysis and used E-view8 software. The study used two dependent variables return on asset (ROA) and return on equity (ROE), six independent variables that are NBE bill purchase, legal reserve requirement, equity investment, capital requirement, capital adequacy and bank size.

description: Latency of Epstein-Barr virus infection may be generated by surviving immortalized B cells or by continuous re-infection. EBV-positive B-cell tumors have been found following bone-marrow transplantation (BMT) and were of donor type in the few cases investigated. We established a B-cell line from the bone marrow of a patient in complete remission following allogeneic BMT for aplastic anemia 18 months post-grafting. Differences in sex and isoenzymes allowed an exact determination of chimerism in our case. While the patient showed persistent complete chimerism of all cell lineages, cells grown in culture were of recipient type. They expressed B-cell markers, showed a monoclonal rearrangement of the immunoglobulin genes and carried EBV-associated antigens. As direct preparations of cells from the patient did not contain detectable recipient-type cells, it appeared likely that small numbers of EBV-transformed B cells of the recipient survived for long periods in this patient. For the development of secondary B-cell neoplasms in vivo, additional patho-physiological steps like severe graft versus host disease or T-cell suppression are obviously required because the patient was still free of lymphoma 3 years post-grafting.

description: Nucleon resonance contributions to the polarized proton $g_1$ and $g_2$ structure functions are computed from resonance electroexcitation amplitudes extracted from CLAS exclusive meson electroproduction data. Including resonances in the mass range up to 1.75 GeV, and taking into account the interference between excited states, we compare the resonant contributions with the polarized proton structure function and polarization asymmetry data from Jefferson Lab 6 GeV measurements. All resonance-like structure observed in the polarized structure functions and asymmetries can be attributed to the resonant contributions, confirming their essential role in the behavior of $g_1$ and $g_2$ in the resonant region over the entire range $Q^2 < 7.5$ GeV$^2$ covered by the measurements. Comparing the resonance contributions with the $g_1$ and $g_2$ structure functions computed from parton distribution functions extrapolated from the deep-inelastic region, we also quantify the degree to which quark-hadron duality holds for $g_1$ and $g_2$ and their moments.

description: Telecom operators should monitor the satisfaction level of their customers and the quality of their networks to take on-time network optimization, redesign and marketing, in general effective resource allocation decisions. Therefore, it is necessary to evaluate the impact of fixed wire-line broadband performances on the customers’ experience. QoE is an emerging technology, it has become an increasing research area. In this thesis, QoE is evaluated with objective and subjective methods. Most of earlier studies used subjective method to evaluate QoE, but the evaluation we used a combination of objective and subjective methods which give more realistic results. Moreover, the nobility of this thesis to the best of my knowledge is a unique combination of network quality metrics. It is based on download, upload speed and latency of QoE objective metrics which are collected from the customers’ end devices, using Testmy.net, ping-test.net tools. Furthermore, we formulate a survey questionnaire to evaluate user MOS
