description: Src tyrosine kinases and spleen tyrosine kinase (Syk) have recently been shown to contribute to sustained platelet aggregation on collagen under arterial shear. In the present study, we have investigated whether Src and Syk are required for aggregation under minimal shear following activation of glycoprotein VI (GPVI) and have extended this to C-type lectin-like receptor-2 (CLEC-2) which signals through the same pathway. Aggregation was induced by the GPVI ligand collagen-related peptide (CRP) and the CLEC-2 ligand rhodocytin and monitored by light transmission aggregometry (LTA). Aggregation and tyrosine phosphorylation by both receptors were sustained for up to 50 min. The addition of inhibitors of Src, Syk or Bruton’s tyrosine kinase (Btk) at 150 sec, by which time aggregation was maximal, induced rapid loss of tyrosine phosphorylation of their downstream proteins, but only Src kinase inhibition caused a weak (~10%) reversal in light transmission. A similar effect was observed when the inhibitors were combined with apyrase and indomethacin or glycoprotein IIb-IIIa (GPIIb-IIIa) antagonist, eptifibatide. On the other hand, activation of GPIIb-IIIa by GPVI in a diluted platelet suspension, as measured by binding of fluorescein isothiocyanate-labeled antibody specific for the activated GPIIb-IIIa (FITC-PAC1), was reversed on the addition of Src and Syk inhibitors showing that integrin activation is rapidly reversible in the absence of outside-in signals. The results demonstrate that Src but not Syk and Btk contribute to sustained aggregation as monitored by LTA, possibly as a result of inhibition of outside-in signaling from GPIIb-IIIa to the cytoskeleton through a Syk-independent pathway. This is in contrast to the role of Syk in supporting sustained aggregation on collagen under arterial shear.

description: We report a weak line at 3.52+/-0.02 keV in X-ray spectra of M31 galaxy and the Perseus galaxy cluster observed by MOS and PN cameras of XMM-Newton telescope. This line is not known as an atomic line in the spectra of galaxies or clusters. It becomes stronger towards the centers of the objects; is stronger for Perseus than for M31; is absent in the spectrum of a deep "blank sky'' dataset. Although for each object it is hard to exclude that the feature is due to an instrumental effect or an atomic line, it is consistent with the behavior of a dark matter decay line. Future (non-)detections of this line in multiple objects may help to reveal its nature.

'They Seem Like a Good Bunch': Liberal Party Support for Violent Croatian Nationalism in Australia 1949-1972
Creators: name: Lee, Alexander
Publisher: name: The Australian National University
Year: 2022

description: The phenomenon of violent Croatian nationalism during the Cold War over the years 1949-1972 was a bitter partisan chapter of Australia's political history. The issue, a small number of emigre Croatians prepared to use violence to achieve their political goals, grew into a significant political controversy in Australia and became a microcosm for the deep political chasm between Australia's major political parties during the Cold War. When violent Croatian nationalists in Australia began to commit acts of violence, the Liberal Party-led government that presided over this period faced fierce criticism. They were accused of inaction, allowing their ideological support for Croatian nationalism to cloud their judgment, and hypocrisy in not prosecuting this issue with the same fervour they had demonstrated in repressing left wing and communist movements. The opposition Labor Party and other elements of the political left became increasingly outraged as acts of suspected Croatian nationalist violence occurred and re-occurred over this period with little reaction from the Liberal-led government. The purpose of this thesis is to examine the role of the Liberal Party in the endurance of this issue in Australia. It considers what they did and did not do to address the violent Croatian nationalist problem in Australia. It does not seek to condemn nor vindicate the Liberal Party and its policies on this issue, rather, to understand and contextualise them. In doing so it reveals a chapter of Australian history far richer and more nuanced than the partisan literature from the period conveyed. This thesis returns to the wealth of rarely examined primary source documents that clearly lay the progression of this issue from the post-war migrant wave that brought a significant number of Croatian nationalists to Australia, to the fall of the Liberal-led government in December 1972 amidst the worst outbreak of nationalistic Croatian violence in Australia. Thus-far this issue has never been considered in isolation in the Australian context, but significant efforts understand Croatian emigre violence have been made in recent years. Further, this thesis connects to diverse range of scholarship considering migration, security, political history, and terrorism studies. The historical record reveals that the Liberal Party was not active supporters of violent Croatian nationalists, but were rhetorically supportive, reluctant to concede that there was any problem, and consistently took light touch policy options that did little to dissuade violent Croatian nationalists in Australia. This conclusion is not only evident in the primary sources, but it is also the conclusion that the Liberal Party cabinet reached in the final weeks of its government.
POST-INDUSTRIAL URBAN AREAS IN THE CONTEXT OF RUINATION, DEMOLITION AND URBAN REGENERATION IN A POST-SOCIALIST CITY: EXPERIENCES OF ŁÓDŹ, POLAND

description: Since the beginning of 1990’s Łódź has become one of the largest and the fastest shrinking cities in Poland and Central-Eastern Europe (Jaroszewska & Stryjakiewicz, 2014). This is the result of political transformation in Poland at the turn of the 1980’s and 1990’s, which caused the collapse of Łódź economy based on textile industry monoculture. The radical population change has triggered highly dynamic transformations in Łódź urban fabric and produced numerous ruins, voidances, not used houses and dwellings, abandoned and vacant land in a contemporary city, especially in its central, historical districts. Furthermore, one of the key role in the process of ruination of Łódź 19th-century urban tissue played the communists who ruled the city without any respect to its urban heritage for almost 50 years from the end of World War II. That was an intentional and ideologically motivated policy. In contrast, new capitalist circumstances of urban development in Poland since political and economic transformation in 1989 have freed private property developer’s ”game of urban space” that has strengthened urban sprawl and decapitalization of historical, especially post-industrial buildings in Łódź downtown. The aim of our research is to identify qualities of post-industrial urban areas in the downtown of Łódź in the period of 1989-2016 and then the role of ruined and abandoned post-industrial buildings in urban regeneration process.

How social movements engage with public deliberation: A multifaceted approach
Creators: name: Guillen Grillo, Sergio
Publisher: name: The Australian National University
Year: 2022

description: This thesis empirically examines how a social movement as a plural, multifaceted body, engages with an ample range of spaces for deliberation. The study centers on the social movement's practices and aspirations when engaging with a variety of spaces for public expression and involvement in decision-making, ranging from Municipal Councils, to Technical Advisory Commissions, to Community Agricultural Festivals. It examines the questions how do social movements engage with public deliberation?, and what are the implications of this engagement for the theory and practice of deliberative democracy?. The empirical research in this thesis is based on an interpretive study of the Costa Rican Movement Against Genetically Modified Organisms (or Movement Against Transgenics MaT) and its practices of engagement with deliberative spaces at the national and local levels between 1999 and 2015. The research project examines this case as an information-rich, revelatory and extreme case of social movement engagement with formal local government decision-making on complex and divisive issues. This thesis proposes three contributions to bridge the study of social movements and public deliberation. First, it takes a broad situated approach to studying how social movements make sense of their practices of engagement with public deliberation, without a restricting it to a pre-conceived role. Second, my analysis expressly recognizes that the activists within the movement do not have a unified perspective about the movement's engagement with public deliberation, or a singular approach for how to relate to outsiders and antagonists. Hence, I have introduced an analytical framework that supports the classification of the specific orientations for this movement according to their features and practices. Finally, the third contribution showcases the diverse ways through which social movements engage with public deliberation. The movement's diversity manifests in a set of loosely converging orientations, each of which assembles a set of compatible aspirations and practices in pursuit of the broader movement goals, namely: 1) partisan resistance, 2) trans-partisan inquiry; and 3) generative empowerment. Grounded on these findings, this work provides concrete insights about how the plurality of orientations can be deployed by deliberative democracy scholars to examine the questions of recognition and inclusion of marginalized perspectives, and the diverse modes of protest and expression. I conclude by recommending possible policy measures that could draw on these findings to enrich the assessment of the country's democratic landscape, gain further insights from activist research, and foster greater leadership in deliberative engagement by key actors in biotechnology and biosafety governance.

description: By using a solution ansatz we partially decouple the metric and the Stuckelberg sectors of the minimal massive gravity (MMGR). In this scheme for a diagonal physical metric we find the general solutions for the scalars of the theory and the particular fiducial (background) metric which leads to these solutions. Then we adopt this general formalism to construct the derivation of new Friedmann-Lemaitre-Robertson-Walker (FLRW) cosmologies of the theory in the presence of a so-called effective ideal fluid which arises from our solution ansatz as a modifying, non-physical source for the Einstein and the corresponding Friedmann equations.

description: Introduction: Birth spacing is the time gaps between two consecutive life births. Optimal spacing until the next pregnancy is generally understood to refer to resting period that allows the mother time to recover from pregnancy, and labour. Family planning programs have advocated three and more year’s intervals between births for infant and child health and survival. Recent research found that the health of mothers and infants with the birth interval of 3 to 5 years is safer than 2 years or less.

Objectives: To assess Prevalence of Suboptimal Child Spacing Practice and Its Associated Factors Among Women of Childbearing Age in Serbo Town,Jimma Zone Southwest Ethiopia, 2017 Ethiopia, from March to April 2017.

description: Pulmonary hypertension (PH) is defined by increased mean pulmonary artery pressure, and the clinical classification includes five etiologies, of which we investigated subgroup 1, pulmonary arterial hypertension (PAH) and subgroup 4, chronic thrombotic and/or embolic disease (CTEPH). Platelets participate in both innate and adaptive immune responses and could possibly contribute to the suggested systemic inflammation associated with PAH. In this study, we utilized flow cytometry to analyze platelet activation and platelet-monocyte (PMA) and granulocyte (PGA) aggregates in PAH and CTEPH patients and healthy control subjects. The plasma concentration of proinflammatory cytokines was measured by multiplex electrochemiluminescence. Our main finding is that circulating platelets are activated in the circulation and form aggregates with both monocytes and granulocytes in patients with idiopathic PAH (IPAH), associated PAH (APAH) and pulmonary hypertension due to CTEPH. There was a strong correlation between the platelet activation, assessed as P-selectin, and the number of aggregates formed. IL-6, IL-8, IL-10 and TNF-α were increased in all PH subgroups as compared to healthy controls, and PMAs were associated with circulating IL-6, IL-8 and IL-10, whereas PGAs were associated with IL-6. The increased concentrations of platelet-leukocyte aggregates found in PAH/CTEPH patients might thus contribute to the inflammatory state in PH.

description: The guarantee of the right to health protection, with the priority of suppressing health inequalities, is a main goal of the Portuguese National Health Service. In this context, the health care access equity in mainland Portugal continues to be a challenge for public health policies, with a littoral territory where health services are concentrated and interior depopulated zones, stripped of health services and condemned to a physical and social isolation. Based on year 2011 data from PORDATA , the present work studies how mortality is related to health services distribution - namely hospital infrastructures, health centres and health professionals - and with population characteristics related to illiteracy and ageing. The results show a strong association between mortality and health services distribution, highlighting that mortality increases with the decrease of health services distribution, worsening when related to population illiteracy and ageing. Results reveal the importance to draw up local level public policies, focused on the socio-cultural specificities of the territories, which are mainly materialized in a distribution of health services closer to isolated populations according to their needs.

description: We present a method for proving that a semigroup is finitely based and find some new sufficient conditions under which a monoid is finitely based. As an application, we find a class of finite monoids where the finite basis property behaves in a complicated way with respect to the lattice operations but can be recognized by a simple algorithm. The method results in a short proof of the theorem of E. Lee that every monoid that satisfies xtxysy = xtyxsy and xytxsy = yxtxsy is finitely based. Also, the method gives an alternative proof of the theorem of F. Blanchet-Sadri that a pseudovariety of n-testable languages is finitely based if and only if n < 4.

description: After launch of the Make in India scheme in 2014, Automobile sector in the country is receiving close attention of the policymakers. On one hand, as the country aspires to emerge as a major exporter of various automobile categories (two, three and four-wheelers, including passenger as well as commercial vehicles) and auto-components, the market is protected by tariff barriers. On the other hand, the sector is integrated with the world through India’s Regional Trade Agreement (RTA) deals, in anticipation of increased market access and consequent export opportunities. However, as India’s tariff level is at a relatively higher plane vis-à-vis partner countries, the possibility of rising imports in the aftermath of the trade agreement cannot be ruled out. In addition, the absence of harmonization of technical standards can also impede the market access for Indian exports, even in the aftermath of deep tariff reforms. The global auto-sector standard harmonization is done under the wings of the United Nations Economic Commission for Europe (UNECE) forums. While India has joined the UNECE 1998 agreement with effect from April 2006, difference in the UNECE forum participation pattern among its current and potential RTA partners might put a dampening effect on India’s future exports. The WITS-SMART tariff reform simulation analysis for ten partner countries indicate that India needs to contemplate on the UNECE membership question closely and evaluate its options judiciously to maximize potential benefits.

description: In this paper we show that the Germani-Kehagias model of Higgs inflation (or New Higgs Inflation), where the Higgs boson is kinetically non-minimally coupled to the Einstein tensor is in perfect compatibility with the latest Planck and BICEP2 data. Moreover, we show that the tension between the Planck and BICEP2 data can be relieved within the New Higgs inflation scenario by a negative running of the spectral index. Regarding the unitarity of the model, we argue that it is unitary throughout the evolution of the Universe. Weak couplings in the Higgs-Higgs and Higgs-graviton sectors are provided by a large background dependent cut-off scale during inflation. In the same regime, the W and Z gauge bosons acquire a very large mass, thus decouple. On the other hand, if they are also non-minimally coupled to the Higgs boson, their effective masses can be enormously reduced. In this case, the W and Z bosons are no longer decoupled. After inflation, the New Higgs model is well approximated by a quartic Galileon with a renormalizable potential. We argue that this can unitarily create the right conditions for inflation to eventually start.

description: The transverse Ising magnet Hamiltonian describing the Ising chain in a transverse magnetic field is the archetypal example of a system that undergoes a transition at a quantum critical point (QCP). The columbite CoNb$_2$O$_6$ is the closest realization of the transverse Ising magnet found to date. At low temperatures, neutron diffraction has observed a set of discrete collective spin modes near the QCP. We ask if there are low-lying spin excitations distinct from these relatively high energy modes. Using the heat capacity, we show that a significant band of gapless spin excitations exists. At the QCP, their spin entropy rises to a prominent peak that accounts for 30$\%$ of the total spin degrees of freedom. In a narrow field interval below the QCP, the gapless excitations display a fermion-like, temperature-linear heat capacity below 1 K. These novel gapless modes are the main spin excitations participating in, and affected, by the quantum transition.

description: We classify all two-dimensional, unitary, rational conformal field theories with two primaries, central charge $c<25$, and arbitrary Wronskian index. In mathematical parlance, we classify all strongly regular vertex operator algebras (VOAs) with central charge $c<25$ and exactly two simple modules. We find that any such theory is either one of the Mathur-Mukhi-Sen (MMS) theories $\mathsf{A}_{1,1}$, $\mathsf{G}_{2,1}$, $\mathsf{F}_{4,1}$, or $\mathsf{E}_{7,1}$, or it is a coset of a chiral algebra with one primary operator (also known as a holomorphic VOA) by such an MMS theory. By leveraging existing results on the classification of holomorphic VOAs, we are able to explicitly enumerate all of the aforementioned cosets and compute their characters. This leads to 123 theories, most of which are new. We emphasize that our work is a bona fide classification of RCFTs, not just of characters. Our techniques are general, and we argue that they offer a promising strategy for classifying chiral algebras with low central charge beyond two primaries.

description: We present a class of exact scalar-tensor black holes for a shift-symmetric part of the Horndeski action. The action includes a higher order scalar tensor interaction term. We find that for a static and spherically symmetric space-time, the scalar field, if time dependent, can be non-trivial and regular thus circumventing in an interesting way no-hair arguments for gallileons. Furthermore, within this class we find a stealth Schwarzschild and a partially self-tuned de-Sitter Schwarzschild black hole, both exhibiting a non trivial and regular space and time dependent scalar. In the latter solution the bulk vacuum energy is screened from a necessarily smaller geometric effective de Sitter vacuum via an integration constant associated to the time dependent scalar field.

description: Recent evidence indicates that the accumulation of endogenous DNA damage can induce senescence and limit the function of adult stem cells. It remains elusive whether deficiency in DNA damage repair is associated with the functional alteration of mammary stem cells. In this article, we reported that senescence was induced in mammary epithelial cells during aging along with increased expression of p16Ink4a (p16), an inhibitor of CDK4 and CKD6. Loss of p16 abrogated the age-induced senescence in mammary epithelial cells and significantly increased mammary stem cell function. We showed that loss of Brca1, a tumor suppressor that functions in DNA damage repair, in the mammary epithelium induced senescence with induction of p16 and a decline of stem cell function, which was rescued by p16 loss. These data not only answer the question as to whether deficiency in DNA damage repair is associated with the functional decline of mammary stem cells, but also identify the role of p16 in suppressing Brca1-deficient mammary stem cell function.

description: Parity-violating fluids in two spatial dimensions can appear in a variety of contexts such as liquid crystal films, anyon fluids, and quantum Hall fluids. Nonetheless, the consequences of parity-violation on the solutions to the equations of motion are largely unexplored. In this paper, we explore phenomenological consequences of parity-violation through simple, illustrative examples. Although incompressible velocity fields are essentially unchanged by parity violation, we discuss examples where parity violation plays a role at boundaries, or in the dynamics of temperature. We then discuss new types of compressible flows which only exist in a parity-violating fluid, including new sound waves, and solitons in the dissipationless limit. We conclude with a discussion of some curious features in Rayleigh-Bénard convection of a parity-violating fluid.

description: There is currently substantial effort being invested into creating efficient thermoelectric nanowires based on topological insulator chalcogenide-type materials. A key premise of these efforts is the assumption that the generally good thermoelectric properties that these materials exhibit in bulk form will translate into similarly good or even better thermoelectric performance of the same materials in nanowire form. Here, we calculate thermoelectric performance of topological insulator nanowires based on Bi2Te3, Sb2Te3 and Bi2Se3 as a function of diameter and Fermi level. We show that the thermoelectric performance of topological insulator nanowires does not derive from the properties of the bulk material in a straightforward way. For all investigated systems the competition between surface states and bulk channel causes a significant modification of the thermoelectric transport coefficients if the diameter is reduced into the sub-10 um range. Key aspects are that the surface and bulk states are optimized at different Fermi levels or have different polarity as well as the high surface to volume ratio of the nanowires. This limits the maximum thermoelectric performance of topological insulator nanowires and thus their application in efficient thermoelectric devices.

description: This paper studies the fundamental limits of the minimum average length of lossless and lossy variable-length compression, allowing a nonzero error probability $ε$, for lossless compression. We give non-asymptotic bounds on the minimum average length in terms of Erokhin's rate-distortion function and we use those bounds to obtain a Gaussian approximation on the speed of approach to the limit which is quite accurate for all but small blocklengths: $$(1 - ε) k H(\mathsf S) - \sqrt{\frac{k V(\mathsf S)}{2 π} } e^{- \frac {(Q^{-1}(ε))^2} 2 }$$ where $Q^{-1}(\cdot)$ is the functional inverse of the standard Gaussian complementary cdf, and $V(\mathsf S)$ is the source dispersion. A nonzero error probability thus not only reduces the asymptotically achievable rate by a factor of $1 - ε$, but this asymptotic limit is approached from below, i.e. larger source dispersions and shorter blocklengths are beneficial. Variable-length lossy compression under an excess distortion constraint is shown to exhibit similar properties.

description: Guaranteed upper-lower bounds on homogenized coefficients, arising from the periodic cell problem, are calculated in a scalar elliptic setting. Our approach builds on the recent variational reformulation of the Moulinec-Suquet (1994) Fast Fourier Transform (FFT) homogenization scheme by Vondřejc et al. (2014), which is based on the conforming Galerkin approximation with trigonometric polynomials. Upper-lower bounds are obtained by adjusting the primal-dual finite element framework developed independently by Dvořák (1993) and Wieckowski (1995) to the FFT-based Galerkin setting. We show that the discretization procedure differs for odd and non-odd number of grid points. Thanks to the Helmholtz decomposition inherited from the continuous formulation, the duality structure is fully preserved for the odd discretizations. In the latter case, a more complex primal-dual structure is observed due to presence of the trigonometric polynomials associated with the Nyquist frequencies. These theoretical findings are confirmed with numerical examples. To conclude, the main advantage of the FFT-based approach over conventional finite-element schemes is that the primal and the dual problems are treated on the same basis, and this property can be extended beyond the scalar elliptic setting.

description: Recent evidence indicates that the accumulation of endogenous DNA damage can induce senescence and limit the function of adult stem cells. It remains elusive whether deficiency in DNA damage repair is associated with the functional alteration of mammary stem cells. In this article, we reported that senescence was induced in mammary epithelial cells during aging along with increased expression of p16Ink4a (p16), an inhibitor of CDK4 and CKD6. Loss of p16 abrogated the age-induced senescence in mammary epithelial cells and significantly increased mammary stem cell function. We showed that loss of Brca1, a tumor suppressor that functions in DNA damage repair, in the mammary epithelium induced senescence with induction of p16 and a decline of stem cell function, which was rescued by p16 loss. These data not only answer the question as to whether deficiency in DNA damage repair is associated with the functional decline of mammary stem cells, but also identify the role of p16 in suppressing Brca1-deficient mammary stem cell function.

description: Die Software-Architektur Dokumentation (SAD) ist ein integrales Artefakt eines Software Projektes. Die SAD trägt zum fortwährenden Erfolg eines Software Projektes bei, indem sie ein gemeinsames Verständnis der Software Architektur gewährleistet, wichtige Entwurfsentscheidungen dokumentiert und einer Erosion der Software vorbeugt. Um die Qualität von SADs zu verbessern und nachgelagerte Aufgaben zu unterstützen, ist eine automatische Klassifizierung dieser Entwurfsentscheidungen erstrebenswert. In dieser Arbeit implementieren und evaluieren wir einen Ansatz zur automatischen Identifikation und Klassifizierung von Entwurfsentscheidungen auf der Grundlage einer feingranularen Taxonomie, bei der wir eine hierarchische Klassifikationsstrategie mit dem Einsatz von Transfer-Lernen durch vortrainierter Sprachmodelle kombinieren. Der Beitrag dieser Arbeit besteht darin, den Vorteil einer hierarchischen Klassifikationsstrategie für die automatische Klassifikation von Entwurfsentscheidungen gegenüber einem nicht-hierarchischen Ansatz zu untersuchen. Außerdem untersuchen und vergleichen wir die Effektivität der vortrainierten Sprachmodelle RoBERTa, XLNet, BERTOverflow und GPT-3 für diese Aufgabe. In unserer Evaluation schnitten die Ansätze mit vortrainierten Sprachmodellen im Allgemeinen besser ab als die Baseline-Ansätze. Wir konnten jedoch keinen klaren Vorteil der hierarchischen Ansätze gegenüber den nicht-hierarchischen Ansätzen in Kombination mit den Sprachmodellen feststelle. Letztlich sind die Ergebnisse dieser Arbeit durch die Größe und das Ungleichgewicht unseres Datensatzes limitiert und erfordern daher weitere Forschung mit einem größeren Datensatz.

description: This article explores the concept of life-space intervention, and proposes four dimensions of a single, unified life-space: The physical dimension, where young people's lives unfold; the mental dimension, reflecting how young people make sense of their life-space; the relational dimension, assigning 'space' to young people's relationships; and, the virtual dimension, constituted by technology-based platforms for the construction of identity as well as by the imagination and fantasies held by young people. The implications of this conceptualization of a multi-dimensional single life-spaced are discussed in relation to being present with young people, and the agency-structure dilemma is explored in relation to generating change in the lives of young people.

description: If we have a system of binary variables and we measure the pairwise correlations among these variables, then the least structured or maximum entropy model for their joint distribution is an Ising model with pairwise interactions among the spins. Here we consider inhomogeneous systems in which we constrain (for example) not the full matrix of correlations, but only the distribution from which these correlations are drawn. In this sense, what we have constructed is an inverse spin glass: rather than choosing coupling constants at random from a distribution and calculating correlations, we choose the correlations from a distribution and infer the coupling constants. We argue that such models generate a block structure in the space of couplings, which provides an explicit solution of the inverse problem. This allows us to generate a phase diagram in the space of (measurable) moments of the distribution of correlations. We expect that these ideas will be most useful in building models for systems that are nonequilibrium statistical mechanics problems, such as networks of real neurons.
