description: Realistic attosecond wave packets have complex profiles that, in dispersive conditions, rapidly broaden or split into multiple components. Such behaviors are encoded in sharp features of the wave packet spectral phase. Here, we exploit the quantum beating between one- and two-photon transitions in an attosecond photoionization experiment to measure the photoelectron spectral phase continuously across a broad energy range. Supported by numerical simulations, we demonstrate that this experimental technique is able to reconstruct sharp fine-scale features of the spectral phase, continuously as a function of energy and across the full spectral range of the pulse train, thus beyond the capabilities of existing attosecond spectroscopies. In a proof-of-principle experiment, we retrieve the periodic modulations of the spectral phase of an attosecond pulse train due to the individual chirp of each harmonic.

description: Automated vehicles have received much attention recently, particularly the DARPA Urban Challenge vehicles, Google's self-driving cars, and various others from auto manufacturers. These vehicles have the potential to significantly reduce crashes and improve roadway efficiency by automating the responsibilities of the driver. Still, automated vehicles are expected to crash occasionally, even when all sensors, vehicle control components, and algorithms function perfectly. If a human driver is unable to take control in time, a computer will be responsible for pre-crash behavior. Unlike other automated vehicles--such as aircraft, where every collision is catastrophic, and guided track systems, which can only avoid collisions in one dimension--automated roadway vehicles can predict various crash trajectory alternatives and select a path with the lowest damage or likelihood of collision. In some situations, the preferred path may be ambiguous. This study investigates automated vehicle crashing and concludes the following: (1) automated vehicles will almost certainly crash, (2) an automated vehicle's decisions preceding certain crashes will have a moral component, and (3) there is no obvious way to effectively encode complex human morals in software. A three-phase approach to developing ethical crashing algorithms is presented, consisting of a rational approach, an artificial intelligence approach, and a natural language requirement. The phases are theoretical and should be implemented as the technology becomes available.

description: Oxidative stress has been identified as an underlying factor in the development of insulin resistance, β-cell dysfunction, impaired glucose tolerance and type 2 diabetes mellitus and it also play major role in kidney stone formation. The present study is aimed to elucidate the in vitro nephroprotective activity of two isoflavonoid glycosides, tectorigenin 7-O-β-D-glucosyl-(1→6)-β-D-glucoside (1) and tectorigenin 7-O-β-D-glucosyl-4′-O-β-D-glucoside (2) isolated from the n-BuOH fraction of Iris spuria L. (Zeal) rhizome MeOH extract against oxalate and high glucose-induced oxidative stress in NRK-49F cells. The results revealed that compounds 1 and 2 significantly increased the antioxidant enzyme activities and decreased MDA levels in both oxalate and high glucose stress. Treatment with these phytochemicals effectively down-regulated expression of crystal modulator genes and pro-fibrotic genes in oxalate and high glucose-mediated stress respectively. This study indicates cytoprotective, antioxidant, anti-urolithic and anti-diabetic effects of compounds 1 and 2 against oxalate and high glucose stress.

description: Multifractal fluctuations in the time dynamics of seismicity data have been analyzed. We investigated the interspike intervals (times between successive earthquakes) of one of the most seismically active areas of central Italy by using the Multifractal Detrended Fluctuation Analysis (MF-DFA). Analyzing the time evolution of the multifractality degree of the series, a loss of multifractality during the aftershocks is revealed. This study aims to suggest another approach to investigate the complex dynamics of earthquakes.

description: The dry powder of MC fruits was extracted by maceration, ultrasonication, liquid-liquid partition and soxhlation. The in vitro antidiabetic and antioxidant assays were used to screen extracts and fractions. Refluxed and liquid partitioned extracts were fractionated using petroleum ether and ethyl acetate and purified with the help of preparative HPLC to give 2 phytoconstituents M1 and M2 respectively. Compound M1 (1) was identified as charantin and Compound M2 (2) was identified as momordicinin using spectral studies. Momordicinin showed potent α-amylase inhibitory activity with IC50 15.86μg/ml which was reported for the first time.

description: The relationship between physical observables defined in lattice models and the associated (quasi-)primary scaling operators of the underlying field-theory is revisited. In the context of local scale-invariance, we argue that this relationship is only defined up to a time-dependent amplitude and derive the corresponding generalizations of predictions for two-time response and correlation functions. Applications to non-equilibrium critical dynamics of several systems, with a fully disordered initial state and vanishing initial magnetization, including the Glauber-Ising model, the Frederikson-Andersen model and the Ising spin glass are discussed. The critical contact process and the parity-conserving non-equilibrium kinetic Ising model are also considered.

description: Since Johann Herder's original eighteenth-century use of the concept culture to critique civilisation's universalising trajectory, the concepts culture and civilisation have evolved in relations of interdependent and complementary opposition, in diverse contexts over time. This thesis explores the development of the relationship between these two concepts, linking their evolution within anthropological thought to the historical and contemporary contexts of their usage in Minahasa, northern Sulawesi, Indonesia. The role of culture and civilisation is examined in both colonial and post-colonial contexts, within discourses promulgated by church and state, and everyday discourse. The geneaology of their usage is traced through nineteenth century missionary and colonial administrative discourse in Minahasa, when civilisation was a key utilitarian concept, into the twentieth-century attention to culture within discourses of Indonesian nationalism and the GMIM (The Christian Evangelical Church in Minahasa) in northern Sulawesi. This thesis examines how the people of the town of Lolah, within Minahasa, use contemporary Indonesian equivalents of the culture-civilisation nexus -the concepts kebudayaan and moderen to make sense of, and orient themselves, in their negotiation of socio-economic, spiritual and cultural change. This is explored through my informants' reflections upon historical processes of change, and contemporary efforts to reconcile certain cultural traditions -articulated as menggali kembali budaya (to dig up and bring back culture) - with a modern Christian worldview. This thesis considers how the concepts culture and civilisation, in complementary opposition, have developed as technologies of the self, related to the development of pastoral power, in the production of civilised/modern, Christian subjects in Minahasa. In this context, culture and civilisation are appreciated as concepts with meta-effects, meaningfully realised in everyday life, producing what they delimit and define: culture and civilisation.
Service oriented approach to high performance scientific computing

description: Service Oriented Architectures (SOA) are used in business circles to harness the distributed resources of an enterprise, with relative ease and convenience. SOA is perceived to deliver programmability, scalability and efficiency under heterogeneity. The scientific community is always aspired to have a similar convenient approach to solve "not so embarrassingly parallel" scientific problems with expected levels of high performance, especially in heterogeneous conditions. One of the major challenges in parallelizing scientific algorithms is their apparent interdependency of tasks (atomic units of parallel works) which results in too fine granularity. The computational advantages in parallelizing those scientific algorithms can be overshadowed by costs involved in communications between non-optimal fine-grained tasks, in a SOA environment. The aim of this PhD research is to overcome these challenges and to empower scientists and researchers with SOA tools to develop high performance scientific applications with relative ease that can perform well under heterogeneous environments. The research has produced a scalable and heterogeneity-oblivious SOA middleware - ANU-SOAM. It implements a popular enterprise SOA middleware API (IBl\II-Platform Symphony API) and thus ensures programmability. It offers better performance under heterogeneous conditions by implementing load balancing and scheduling techniques. Along with its compute services it provides a Data Service which helps application programmers to develop codes that can effectively circumvent the interdependency of tasks and thereby reduce communications to ensure high performance outcomes. The Data Service achieves this by allowing data to be stored, accessed, modified and synchronized (using add, get, put and sync functionalities) at host and compute nodes according to the application logic. It is also observed that the programming model supported by the Data Service can help ANU-SOAM applications to access compute resources in a "Cloud IaaS" over high latency networks (like the Internet) with much lower overheads compared to the conventional SOA programming models.

description: We present the first cosmological simulations of primordial magnetic fields derived from the constraints by the Cosmic Microwave Background observations, based on the fields' gravitational effect on cosmological perturbations. We evolved different primordial magnetic field models with the {\enzo} code and compared their observable signatures (and relative differences) in galaxy clusters, filaments and voids. The differences in synchrotron radio powers and Faraday Rotation measure from galaxy clusters are generally too small to be detected, whereas differences present in filaments will be testable with the higher sensitivity of the Square Kilometre Array. However, several statistical full-sky analyses, such as the cross-correlation between galaxies and diffuse synchrotron power, the Faraday Rotation structure functions from background radio galaxies, or the analysis of arrival direction of Ultra-High-Energy Cosmic Rays, can already be used to constrain these primordial field models.

Remittances as informal social insurance : a case study of Vietnam

description: Like other developing countries, Vietnam's social security system is not universal as well as regressive and inefficient. It does not cover everyone, especially the poor and vulnerable. In response a large proportion of the population must rely on migration and migrant remittances. Do remittances play an informal social insurance role via poverty reduction, inequality reduction and unexpected shock effects relief? Are remittances crowed out by public transfers? This dissertation will answer these two questions. Chapter 1 explains why the questions are important. Chapter 2 overviews changes in Vietnamese socio-economy leading to large migration flows, explores the weakness of current social security arrangements and explains why remittances become important. This chapter also gives an analytical analysis of the role of remittances in poverty reduction and inequality reduction in comparison with public transfers. The role of remittances in the case of unexpected household negative shocks is tested in Chapter 3. This chapter solves two econometric problems (time-invariant unobservable variables and endogeneity) by applying the first-differencing method and the instrumental variable approach. Chapter 4 tests whether crowding out effects on remittances by public transfers can become a problem. A non-linear functional form is applied instead of linear functional form to test the relationship between remittances and recipient's pre-remittance income. Chapter 5 summarizes all the results from chapters 2, 3 and 4 and gives recommendations. -- provided by Candidate.

description: We theoretically consider the amplification of THz radiation in a superlattice Bloch oscillator. The main dilemma in the realization of THz Bloch oscillator is finding operational conditions which allow simultaneously to achieve gain at THz frequencies and to avoid destructive space-charge instabilities. A possible solution to this dilemma is the extended Limited Space-Charge Accumulation scheme of Kroemer (H. Kroemer, cond-mat/0009311). Within the semiclassical miniband transport approach we extend its range of applicability by considering a difference in the relaxation times for electron velocity and electron energy. The kinetics of electrons and fields establishing a stationary signal in the oscillator is also discussed.

description: B20-type compounds, such as MnSi and FeGe, host helimagnetic and skyrmion phases at the mesoscale, which are canonically explained by the combination of ferromagnetic isotropic interactions with weaker chiral Dzyaloshinskii-Moriya ones. Mysteriously, MnGe evades this paradigm as it displays a noncollinear magnetic state at a much shorter nanometer scale. Here we show that the length scale and volume-dependent magnetic properties of MnGe stem from purely isotropic exchange interactions, generally obtained in the paramagnetic state. Our approach is validated by comparing MnGe with the canonical B20-helimagnet FeGe. The free energy of MnGe is calculated, from which we show how triple-q magnetic states can stabilize by adding higher-order interactions.

description: We report a ^{59}Co Knight shift measurement in a single crystal of the cobalt oxide superconductor Na_{x}CoO_2\cdot1.3H_2O (T_c=4.25 K). We find that the shift due to the spin susceptibility, K^s, is substantially large and anisotropic, with the spin shift along the a-axis K^s_a being two times that along the c-axis K^s_c. The shift decreases with decreasing temperature (T) down to T\sim100 K, then becomes a constant until superconductivity sets in. Both K^s_a and K^s_c decrease below T_c. Our results indicate unambiguously that the electron pairing in the superconducting state is in the spin singlet form.

description: Cephalopod squid, Uroteuthis (Photololigo) duvaucelii is consumed as culinary delicacy along the southwest part of Asian continent. Ethyl acetate:methanol extract of U. duvaucelii was chromatographically fractionated to yield C19 furano-norditerpenoid (1) along with irregular C15 sesquiterpenoid (2) and C20 diterpenoid compounds (3). In vitro anti-inflammatory and antioxidant analyses were utilised to evaluate their bio-potentials. The C19 furano-norditerpenoid was reported for significantly effective 2,2-diphenyl-1-picrylhydrazyl radical inhibition (IC50 0.60 mg/mL) than other compounds and α-tocopherol (IC50 ≥ 0.64 mg/mL). The 2,2’-azino-bis-3-ethylbenzothiozoline-6-sulfonic acid inhibition and ferrous ion chelating potentials were higher for compounds 1 and 2 (IC50 ∼ 0.69 and ∼0.84 mg/mL, respectively) compared to α-tocopherol (IC50 0.76–0.95 mg/mL). The studied compounds displayed comparable inhibitory activities with synthetic ibuprofen against pro-inflammatory inducible 5-lipoxygenase (IC50 ∼ 0.92 mg/mL). The lower hydrophobicity and steric variables were directly correlated with their antioxidative and anti-inflammatory properties. The studied compounds could be utilised as natural antioxidants and anti-inflammatory functional food ingredients.

description: We present DEGARI (Dynamic Emotion Generator And ReclassIfier), an explainable system for emotion attribution and recommendation. This system relies on a recently introduced commonsense reasoning framework, the TCL logic, which is based on a human-like procedure for the automatic generation of novel concepts in a Description Logics knowledge base. Starting from an ontological formalization of emotions based on the Plutchik model, known as ArsEmotica, the system exploits the logic TCL to automatically generate novel commonsense semantic representations of compound emotions (e.g. Love as derived from the combination of Joy and Trust according to Plutchik). The generated emotions correspond to prototypes, i.e. commonsense representations of given concepts, and have been used to reclassify emotion-related contents in a variety of artistic domains, ranging from art datasets to the editorial contents available in RaiPlay, the online platform of RAI Radiotelevisione Italiana (the Italian public broadcasting company). We show how the reported results (evaluated in the light of the obtained reclassifications, the user ratings assigned to such reclassifications, and their explainability) are encouraging, and pave the way to many further research directions.

Emerging whole from Native-Canadian relations: mixed ancestry narratives: a thesis
Creators: name: Marsden, Dawn
Publisher: name: University of British Columbia
Year: 2009

description: After hundreds of years of contact, the relationships between the people of Native Nations and the Canadian Nation are still filled with turmoil. This is common knowledge. What isn't well known, are the personal consequences for children who have Native and non-Native ancestors. This thesis is written with the assistance of eight people of mixed ancestry, who share their experiences, ideas, strategies and dreams, to help others who are dealing with similar issues. This thesis has been organized around the dominant themes and commonalities that have emerged out of eight interviews, into four sections: CONTEXT, CHALLENGES, STRATEGIES & GIFTS. The context that mixed ancestry individuals are born into is complex. Euro-Canadian designs on Native lands and resources resulted in policies that had, and continue to have, a devastating effect on Native people. Legal manipulations of Native identity, in particular, have resulted in the emergence of hierarchies of belonging. Such hierarchies are maintained by enduring stereotypes of "Indianness" and "Whiteness". For some mixed ancestry individuals, negotiating the polarized hierarchies of Native and Canadian societies can result in feelings of being split, and the need to harmonize aspects of the self, with varying social environments. Various strategies are used to deal with such issues, internally and externally. Ultimately, through choices, strategies and transformations, it is possible to transcend the challenges of mixed ancestry, and to lead more fulfilling lives. My hope is that this thesis will be of assistance to people of mixed ancestry and to those trying to understand the complexities of Native- Canadian relations, at least to the point of inspiring more discussions and research.

description: We investigate monogamy relations and upper bounds for generalized $W$-class states related to the Rényi-$α$ entropy. First, we present an analytical formula on Rényi-$α$ entanglement (R$α$E) and Rényi-$α$ entanglement of assistance (REoA) of a reduced density matrix for a generalized $W$-class states. According to the analytical formula, we show monogamy and polygamy relations for generalized $W$-class states in terms of R$α$E and REoA. Then we give the upper bounds for generalized $W$-class states in terms of R$α$E. Next, we provide tighter monogamy relations for generalized $W$-class states in terms of concurrence and convex-roof extended negativity and obtain the monogamy relations for R$α$E by the analytical expression between R$α$E and concurrence. Finally, we apply our results into quantum games and present a new bound of the nonclassicality of quantum games restricting to generalized $W$-class states.

description: Heartbeat stars are eccentric binaries exhibiting characteristic shape of brightness changes during periastron passage caused by tidal distortion of the components. Variable tidal potential can drive tidally excited oscillations (TEOs), which are usually gravity modes. Studies of heartbeat stars and TEOs open a new possibility to probe interiors of massive stars. There are only a few massive (masses of components $\gtrsim 2 $M$_\odot$) systems of this type known. Using TESS data from the first 16 sectors, we searched for new massive heartbeat stars and TEOs using a sample of over 300 eccentric spectroscopic binaries. We analysed TESS 2-min and 30-min cadence data. Then, we fitted Kumar's analytical model to the light curves of stars showing heartbeats and performed times-series analysis of the residuals searching for TEOs and periodic intrinsic variability. We found 20 massive heartbeat systems, of which seven show TEOs. The TEOs occur at harmonics of orbital frequencies in the range between 3 and 36, with the median value equal to 9, lower than those in known Kepler systems with TEOs. The most massive system in this sample is the quadruple star HD 5980, a member of Small Magellanic Cloud. With the total mass of $\sim$150 M$_{\odot}$ it is the most massive system showing a heartbeat. Six stars in the sample of the new heartbeat stars are eclipsing. Comparison of the parameters derived from fitting Kumar's model and from light-curve modelling shows that Kumar's model does not provide reliable parameters. Finally, intrinsic pulsations of $β$ Cep, SPB, $δ$ Sct, and $γ$ Dor-type were found in nine heartbeat systems. This opens an interesting possibility of studies of pulsation-binarity interaction and the co-existence of forced and self-excited oscillations.

description: Brane-World models suggest modification of Newton's law of gravity on the 3-brane at submillimeter scales. The brane-world induced corrections are in higher powers of inverse distance and appear as additional terms with the Newtonian potential. The average inter-particle distance in white dwarf and neutron stars are $10^{-10} cms$ and $10^{-13} cms$ respectively, and therefore, the effect of submillimeter corrections needs to be investigated. We show, by carrying out simple manybody calculations, that the mass and mass-radius relationship of the white dwarf and neutron stars are not effected by submillimeter corrections. However, our analysis shows that the correction terms in the effective theory give rise to force akin to surface tension in normal liquids.

description: The order $α_s^2 α$ mixed QCD and weak corrections to top quark pair production by quark antiquark annihilation are computed, keeping the full dependence on the $t$ and $\bar t$ spins. We determine the contributions to the cross section and to single and double top spin asymmetries at the parton level. These results are necessary ingredients for precise standard model predictions of top quark observables, in particular of top spin-induced parity-violating angular correlations and asymmetries at hadron colliders.

description: We review recent developments in the understanding of meson properties as solutions of the Bethe-Salpeter equation in rainbow-ladder truncation. Included are recent results for the pseudoscalar and vector meson masses and leptonic decay constants, ranging from pions up to c\bar{c} bound states; extrapolation to b\bar{b} states is explored. We also present a new and improved calculation of F_π(Q^2) and an analysis of the πγγtransition form factor for both π(140) and π(1330). Lattice-QCD results for propagators and the quark-gluon vertex are analyzed, and the effects of quark-gluon vertex dressing and the three-gluon coupling upon meson masses are considered.

description: We consider an obliquely reflected Brownian motion $Z$ with positive drift in a quadrant stopped at time $T$, where $T:=\inf \{ t>0 : Z(t)=(0,0) \}$ is the first hitting time of the origin. Such a process can be defined even in the non-standard case where the reflection matrix is not completely-$\mathcal{S}$. We show that in this case the process has two possible behaviors: either it tends to infinity or it hits the corner (origin) in a finite time. Given an arbitrary starting point $(u,v)$ in the quadrant, we consider the escape (resp. absorption) probabilities $\mathbb{P}_{(u,v)}[T=\infty]$ (resp. $\mathbb{P}_{(u,v)}[T

Phase space and quark mass effects in neutrino emissions in a color superconductor

description: We study the phase space for neutrino emissions with massive quarks in direct Urca processes in normal and color superconducting quark matter. We derive in QCD and the NJL model the Fermi momentum reduction resulting from Fermi liquid properties which opens up the phase space for neutrino emissions. The relation between the Fermi momentum and chemical potential is found to be $p_{F}\approxμ(1-κ)$ with $κ$ depending on coupling constants. We find in the weak coupling regime that $κ$ is a monotonously increasing function of the chemical potential. This implies quenched phase space for neutrino emissions at low baryon densities. We calculate neutrino emissivities with massive quarks in a spin-one color superconductor. The quark mass corrections are found to be of the same order as the contributions in the massless case, which will bring sizable effects on the cooling behavior of compact stars.

Impersonation-as-a-Service: Characterizing the Emerging Criminal Infrastructure for User Impersonation at Scale

Publisher: name: arXiv
Year: 2020
Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: In this paper we provide evidence of an emerging criminal infrastructure enabling impersonation attacks at scale. Impersonation-as-a-Service (ImpaaS) allows attackers to systematically collect and enforce user profiles (consisting of user credentials, cookies, device and behavioural fingerprints, and other metadata) to circumvent risk-based authentication system and effectively bypass multi-factor authentication mechanisms. We present the ImpaaS model and evaluate its implementation by analysing the operation of a large, invite-only, Russian ImpaaS platform providing user profiles for more than $260'000$ Internet users worldwide. Our findings suggest that the ImpaaS model is growing, and provides the mechanisms needed to systematically evade authentication controls across multiple platforms, while providing attackers with a reliable, up-to-date, and semi-automated environment enabling target selection and user impersonation against Internet users as scale.

Quantum-mechanical generation of gravitational waves in braneworld

description: We study the quantum-mechanical generation of gravitational waves during inflation on a brane embedded in a five-dimensional anti-de Sitter bulk. To make the problem well-posed, we consider the setup in which both initial and final phases are given by a de Sitter brane with different values of the Hubble expansion rate. Assuming that the quantum state is in a de Sitter invariant vacuum in the initial de Sitter phase, we numerically evaluate the amplitude of quantum fluctuations of the growing solution of the zero mode in the final de Sitter phase. We find that the vacuum fluctuations of the initial Kaluza-Klein gravitons as well as of the zero mode gravitons contribute to the final amplitude of the zero mode on small scales, and the power spectrum is quite well approximated by what we call the rescaled spectrum, which is obtained by rescaling the standard four-dimensional calculation following a simple mapping rule. Our results confirm the speculation raised in Ref. \cite{Kobayashi:2003cn} before.

Embedding Meta-Textual Information for Improved Learning to Rank

description: Neural approaches to learning term embeddings have led to improved computation of similarity and ranking in information retrieval (IR). So far neural representation learning has not been extended to meta-textual information that is readily available for many IR tasks, for example, patent classes in prior-art retrieval, topical information in Wikipedia articles, or product categories in e-commerce data. We present a framework that learns embeddings for meta-textual categories, and optimizes a pairwise ranking objective for improved matching based on combined embeddings of textual and meta-textual information. We show considerable gains in an experimental evaluation on cross-lingual retrieval in the Wikipedia domain for three language pairs, and in the Patent domain for one language pair. Our results emphasize that the mode of combining different types of information is crucial for model improvement.
