description: Type Ia supernovae (SNe Ia) are standardizable candles that must be modeled empirically to yield cosmological constraints. To understand the robustness of this modeling to variations in the model training procedure, we build an end-to-end pipeline to test the recently developed SALT3 model. We explore the consequences of removing pre-2000s low-$z$ or poorly calibrated $U$-band data, adjusting the amount and fidelity of SN Ia spectra, and using a model-independent framework to simulate the training data. We find the SALT3 model surfaces are improved by having additional spectra and $U$-band data, and can be shifted by $\sim 5\%$ if host galaxy contamination is not sufficiently removed from SN spectra. We find that resulting measurements of $w$ are consistent to within $2.5\%$ for all training variants explored in this work, with the largest shifts coming from variants that add color-dependent calibration offsets or host galaxy contamination to the training spectra, and those that remove pre-2000s low-$z$ data. These results demonstrate that the SALT3 model training procedure is largely robust to reasonable variations in the training data, but that additional attention must be paid to the treatment of spectroscopic data in the training process. We also find that the training procedure is sensitive to the color distributions of the input data; the resulting $w$ measurement can be biased by $\sim2\%$ if the color distribution is not sufficiently wide. Future low-$z$ data, particularly $u$-band observations and high signal-to-noise ratio SN Ia spectra, will help to significantly improve SN Ia modeling in the coming years.

Seepage scald : a case study in southeastern New South Wales

Publisher: name: The Australian National University
Year: 1989
Subjects: soil salinity, dry scald, seepage scald, soil erosion

description: Dryland salinity in Australia is usually subdivided into two categories, scald and saline seepage, however, the use of these terms has not been consistent. The existence of a groundwater discharge condition should form the basis for distinguishing different areas of dryland salinity, but areas both with and without this condition have been labelled as ‘scalds’. It is suggested that ’seepage scald’ and ‘dry scald’ be used to distinguish scalds with a groundwater discharge condition from those scalds without while retaining the descriptive qualities of the term ‘scald’. Further, it is suggested that soils labelled as saline seepages fall into the seepage scald category. This study addresses the problem of seepage scald in southeastern New South Wales. There is very little information concerning the soil and hydrological properties of these areas and a case study of the Yarralaw seepage scald was undertaken to answer questions concerning the scald’s location, the threat of scald expansion, possible offsite effects and the scald’s origin. The results of this study have application to a number of similar sites in southeastern New South Wales.

description: The discovery and characterization of exoplanetary systems is a new exciting field. At just over two decades old, it has already fundamentally reshaped our knowledge of planet and solar system formation. We now know that there is a vast diversity of planetary systems, in highly varied, even bizarre, configurations. Known planetary bodies span all masses from objects less massive and smaller than Earth to objects as large as the smallest stars or brown dwarfs. They exhibit periods of but a few hours to periods spanning millennia, from nearly perfectly circular orbits to highly elliptical, from fluffy gas giants to dense rocky worlds, from purely metallic worlds to water worlds. Exoplanets come in all sizes, compositions and varieties. These new discoveries have fundamentally changed the way we approach planetary science. With such a great diversity in exoplanets, we look extend our knowledge to including understanding their individual composition. We wish to understand the climate of these exoplanets and to resolve the differences between, for example, Earth-like and Venus-like planets.
To facilitate these discoveries several methods of exoplanery detection and characterization have been developed. Among them are indirect methods that infer the existence of exoplanets from their influence on their star, and direct methods that detect the light from the exoplanets themselves. Direct detection of exoplanets allows not only for a determination of the existence of the object, but also for the determination of its composition and climate through the measurement of its atmosphere's chemical composition. Using purely high-contrast direct imaging methods, coarse spectra can now be measured for exoplanets with a relative brightness 10⁻⁴-10⁻⁵ below that of the host star. Below this contrast level the companion is at the same level of brightness as the noise caused by optical defects and wave front errors in the observed light, called speckles.
In this thesis, I demonstrate the usage and optimization of a new novel technique, S4_Spectrum, to model and remove speckle noise from directly imaged systems. S4_Spectrum is capable of reducing 99% of the speckle noise. This allows for the detection and spectral characterization of exoplanets as faint as 10⁻⁶-10⁻⁷ times the brightness of their host stars. This represents two orders of magnitude gain in sensitivity. I present the design of one of these high-contrast systems, Project 1640, as well as the data collection method, including the data pipeline and analysis techniques. Also, I describe the S4_Spectrum technique in detail, as implemented in Project 1640, and present its operation and optimization. Additionally, I present the application of this new tool to obtain several spectral characterizations of objects found in the Project 1640 survey.
Late-Time Evolution of Charged Gravitational Collapse and Decay of Charged Scalar Hair - II

description: We study analytically the initial value problem for a charged massless scalar-field on a Reissner-Nordström spacetime. Using the technique of spectral decomposition we extend recent results on this problem. Following the no-hair theorem we reveal the dynamical physical mechanism by which the charged hair is radiated away. We show that the charged perturbations decay according to an inverse power-law behaviour at future timelike infinity and along future null infinity. Along the future outer horizon we find an oscillatory inverse power-law relaxation of the charged fields. We find that a charged black hole becomes ``bald'' slower than a neutral one, due to the existence of charged perturbations. Our results are also important to the study of mass-inflation and the stability of Cauchy horizons during a dynamical gravitational collapse of charged matter in which a charged black-hole is formed.

description: Organizations that develop and deploy artificial intelligence (AI) systems need to manage the associated risks - for economic, legal, and ethical reasons. However, it is not always clear who is responsible for AI risk management. The Three Lines of Defense (3LoD) model, which is considered best practice in many industries, might offer a solution. It is a risk management framework that helps organizations to assign and coordinate risk management roles and responsibilities. In this article, I suggest ways in which AI companies could implement the model. I also discuss how the model could help reduce risks from AI: it could identify and close gaps in risk coverage, increase the effectiveness of risk management practices, and enable the board of directors to oversee management more effectively. The article is intended to inform decision-makers at leading AI companies, regulators, and standard-setting bodies.

POD-based reduced order methods for optimal control problems governed by parametric partial differential equation with varying boundary control
Creators: name: Strazzullo, Maria
name: Vicini, Fabio
Publisher: name: arXiv
Year: 2022
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: In this work we propose tailored model order reduction for varying boundary optimal control problems governed by parametric partial differential equations. With varying boundary control, we mean that a specific parameter changes where the boundary control acts on the system. This peculiar formulation might benefit from model order reduction. Indeed, fast and reliable simulations of this model can be of utmost usefulness in many applied fields, such as geophysics and energy engineering. However, varying boundary control features very complicated and diversified parametric behaviour for the state and adjoint variables. The state solution, for example, changing the boundary control parameter, might feature transport phenomena. Moreover, the problem loses its affine structure. It is well known that classical model order reduction techniques fail in this setting, both in accuracy and in efficiency. Thus, we propose reduced approaches inspired by the ones used when dealing with wave-like phenomena. Indeed, we compare standard proper orthogonal decomposition with two tailored strategies: geometric recasting and local proper orthogonal decomposition. Geometric recasting solves the optimization system in a reference domain simplifying the problem at hand avoiding hyper-reduction, while local proper orthogonal decomposition builds local bases to increase the accuracy of the reduced solution in very general settings (where geometric recasting is unfeasible). We compare the various approaches on two different numerical experiments based on geometries of increasing complexity.

description: We consider a billiard model of a self-bound, interacting three-body system in two spatial dimensions. Numerical studies show that the classical dynamics is chaotic. The corresponding quantum system displays spectral fluctuations that exhibit small deviations from random matrix theory predictions. These can be understood in terms of scarring caused by a 1-parameter family of orbits inside the collinear manifold.

description: "In the West, Greco-Roman studies are commonly called classical studies, but not in the
East. Europeans, the heirs to Greco-Roman civilization, affixed the modifier “classical” in
admiration for their mother culture, but Asians equally had their own version of classical
literature, art, philosophy, and history. Nevertheless, Greco-Roman studies attracted Asians in
the Far East who live farthest from Greco-Roman influence and who inherited neither its
linguistic nor cultural legacy. It entered Asia in the 19th century. When Europeans and
Americans intruded into Asia in the 19th century, they brought not only the Bible and opium but
also their pedagogy. Seeing that European/American education begins from Greco-Roman
studies, Asian intellectuals who tried to learn from Europeans and adopt their culture developed
interests in these studies as well. To avoid confusion with their own classical studies, they
preferred the name Greco-Roman studies, which I shall use as well for the same reason. Among
Greco-Roman studies in East Asia, this thesis will focus on South Korean studies of Roman
history, particularly of Tiberius Gracchus’ agrarian reform. Yet, before we arrive at the moment
when Korean scholars took up this topic, let us briefly browse Korean historiography of Roman
history."

description: When a particle moves around a Kerr black hole, it radiates gravitational waves.Some of these waves are absorbed by the black hole. We calculate such absorption of gravitational waves induced by a particle of mass mu in a circular orbit on an equatorial plane around a Kerr black hole of mass M. We assume that the velocity of the particle v is much smaller than the speed of light c and calculate the energy absorption rate analytically. We adopt an analytic technique for the Teukolsky equation developed by Mano, Suzuki and Takasugi. We obtain the energy absorption rate to O((v/c)^8) compared to the lowest order. We find that the black hole absorption occurs at O((v/c)^5) beyond the Newtonian-quadrapole luminosity at infinity in the case when the black hole is rotating, which is O((v/c)^3) lower than the non-rotating case. Using the energy absorption rate, we investigate its effects on the orbital evolution of coalescing compact binaries.

description: This Special Issue of the Journal “Review of Science, Mathematics and ICT Education” is dedicated to the Educational Robotics in Primary Education. There is currently a real enthusiasm for educational robotics which is supported by the incessant emergence of new educational robots and articles published by the media. Undoubtedly, at least at the level of primary education, a new wave of technology appeared in order for concepts of programming (or "coding") sweeps to be applied, which consequently raises the question of what it can bring to teachers and learners over time. At the same time, scientific research in this field is making significant progress in recent years by providing interesting results in both basic and applied research. On the other hand, there are many challenges with obtaining data with respect to the appropriation of this type of approach by teachers. Indeed, initial and in-service training of teachers is a major challenge to develop learning activities with educational robots which help develop specific learning objectives as well as the development of high-order thinking skills.

E-commerce users' preferences for delivery options

description: Many e-commerce marketplaces offer their users fast delivery options for free to meet the increasing needs of users, imposing an excessive burden on city logistics. Therefore, understanding e-commerce users' preference for delivery options is a key to designing logistics policies. To this end, this study designs a stated choice survey in which respondents are faced with choice tasks among different delivery options and time slots, which was completed by 4,062 users from the three major metropolitan areas in Japan. To analyze the data, mixed logit models capturing taste heterogeneity as well as flexible substitution patterns have been estimated. The model estimation results indicate that delivery attributes including fee, time, and time slot size are significant determinants of the delivery option choices. Associations between users' preferences and socio-demographic characteristics, such as age, gender, teleworking frequency and the presence of a delivery box, were also suggested. Moreover, we analyzed two willingness-to-pay measures for delivery, namely, the value of delivery time savings (VODT) and the value of time slot shortening (VOTS), and applied a non-semiparametric approach to estimate their distributions in a data-oriented manner. Although VODT has a large heterogeneity among respondents, the estimated median VODT is 25.6 JPY/day, implying that more than half of the respondents would wait an additional day if the delivery fee were increased by only 26 JPY, that is, they do not necessarily need a fast delivery option but often request it when cheap or almost free. Moreover, VOTS was found to be low, distributed with the median of 5.0 JPY/hour; that is, users do not highly value the reduction in time slot size in monetary terms. These findings on e-commerce users' preferences can help in designing levels of service for last-mile delivery to significantly improve its efficiency.

description: The (1+1)-dimensional gauge model of two complex self-interacting scalar fields that interact with each other through an Abelian gauge field and a quartic scalar interaction is considered. It is shown that the model has nontopological soliton solutions describing soliton systems consisting of two Q-ball components possessing opposite electric charges. The two Q-ball components interact with each other through the Abelian gauge field and the quartic scalar interaction. The interplay between the attractive electromagnetic interaction and the repulsive quartic interaction leads to the existence of symmetric and nonsymmetric soliton systems. Properties of these systems are investigated by analytical and numerical methods. The symmetric soliton system exists in the whole allowable interval of the phase frequency, whereas the nonsymmetric soliton system exists only in some interior subinterval. Despite the fact that these soliton systems are electrically neutral, they nevertheless possess nonzero electric fields in their interiors. It is found that the nonsymmetric soliton system is more preferable from the viewpoint of energy than the symmetric one. Both symmetric and nonsymmetric soliton systems are stable to the decay into massive scalar bosons.

NLO Effects in QCD Sum-Rule Analyses of $f_{0}(500)$ as a Tetraquark state

description: QCD sum-rule studies have been useful to understand and get an insight on the structure of exotic states, such as tetraquark systems. Moreover, the majority of these studies are performed only at leading-order (LO) within the light tetraquarks systems picture, overlooking the effects of higher order corrections, thus motivating our analysis. Our study focused on the effects of next-to-leading order (NLO) contributions to the mass estimates of the lightest tetraquark state ($J^{PC} = 0^{++}$), the so-called $σ$ or $f_{0}(500)$, using ratios of QCD Laplace sum-rules. A variety of different models were used, which included multiple resonances and width effects, resulting in a final mass prediction of $0.52\,\text{GeV}< m_σ< 0.77\,\text{GeV}$. Even though the ratios of sum-rules demonstrated some insensitivity under superficially large NLO contributions, they added the beneficial feature of canceling the dependence on the anomalous dimension. Our findings were in good agreement with patterns found in Chiral Lagrangian studies regarding the four-quark structure of the $σ$ state, including the relative coupling strengths within the multiple resonance analysis.

description: Summation-by-parts (SBP) operators have been used in the finite difference framework, providing means to prove conservation and discrete stability by the energy method, predominantly for linear (or linearised) equations. Recently, there have been some approaches to generalise the notion of SBP operators and to apply these ideas to other methods. The correction procedure via reconstruction (CPR), also known as flux reconstruction (FR) or lifting collocation penalty (LCP), is a unifying framework of high order methods for conservation laws, recovering some discontinuous Galerkin, spectral difference and spectral volume methods. Using a reformulation of CPR methods relying on SBP operators and simultaneous approximation terms (SATs), conservation and stability are investigated, recovering the linearly stable CPR schemes of Vincent et al. (2011, 2015). Extensions of SBP methods with diagonal-norm operators to Burgers’ equation are possible by a skew-symmetric form and the introduction of additional correction terms. An analytical setting allowing a generalised notion of SBP methods including modal bases is described and applied to Burgers’ equation, resulting in an extension of the previously mentioned skew-symmetric form. Finally, an extension of the results to multiple space dimensions is presented.

description: High performance lead zirconate titanate (PZT) ceramics with aligned porosity for sensing applications were fabricated by an ice-templating method. To demonstrate the enhanced properties of these materials and their potential for sensor and hydrophone applications, the piezoelectric voltage constants hydrostatic parameters and AC conductivity as a function of the porosity in directions both parallel and perpendicular to the freezing temperature gradient were studied. As the porosity level was increased, PZT poled parallel to the freezing direction exhibited the highest coefficients, and hydrostatic figures of merit compared to the dense and PZT poled perpendicular to the freezing direction. This work demonstrates that piezoelectric ceramics produced with aligned pores by freeze casting are a promising candidate for a range of sensor applications and the polarisation orientation relative to the freezing direction can be used to tailor the microstructure and optimise sensitivity for sensor and hydrostatic transducer applications.

In the PAL project all developments from the work packages have been integrated in early stages in an iterative manner, providing a running system that can be used by the different stakeholders. As such, all outcomes from WP2 were immediately integrated in the PAL system. This means, for example, that the pal authoring tool (PAL control, Task 2.1) was already integrated in the PAL system when it was ready. In this document we will highlight how the final developments of robot style, action explanation, PAL inform and PAL control were integrated in the final experiment in 2018/19.

description: This dissertation explores the path of Tibet’s economic integration with China in the first half of the twentieth century. It particularly examines the borderland region of Kham that encompasses parts of present-day Sichuan, Qinghai, and Yunnan. Drawing on borderland histories and bringing together Tibetan and Chinese archival sources, it focuses on indigenous institutions and local economic practices in order to demonstrate that the twentieth-century Sino-Tibetan integration was mediated primarily by Tibetan economic institutions and actors. While previous scholarship has examined the history of Kham in relation to Chinese state-building practices, this dissertation acknowledges the equally important place of Tibetan state-building practices and their impact on the region. As a borderland, Kham was caught between two modernizing states with conflicting agendas. Understanding its economic history, I argue, requires a direct engagement with the Tibetan financial and monetary structures, taxation practices, and labor regimes that not only dominated life Kham but also conditioned the development of the Chinese state itself in the frontiers. Chinese officials frequently collided, clashed, and collaborated with local Tibetan leaders, while Chinese merchants and companies engaged in trade and partnered with and worked alongside Tibetan merchant companies, whose economic reach extended from Shanghai to Calcutta. This dissertation focuses on four main institutions to rethink this history on the Chinese borderlands by focusing on the indigenous Tibetan institutions and structures: ulak conscript labor, currency, monasteries, and merchant companies. All four of these institutions were rooted in Tibetan socio-economic practices and were critical in the transformation of Tibetan society in the Sino-Tibetan borderland. The economic interconnectedness of the twentieth century and the increased links between Tibet and China brought a simultaneous and seemingly contradictory economic trajectory to Tibet. As the Chinese presence on the plateau increased, so did the power of Tibetan economic institutions, for the Chinese government, military, and merchants had to rely on them to exist. In a politically and economically fragmented environment, Tibetan institutions challenged state building efforts and thrived by asserting their own political, religious, and economic power across the Tibetan Plateau and beyond. A history of Tibetan economy as seen and written through the eyes of the Tibetans offers a new perspective to not only rethink modern Chinese history, but also the present day in which the Tibetan institutions still continue to mediate social and economic life on the fringes of the People’s Republic of China.

An interplay between Minkowskian and Euclidean pictures turns out to be non-trivial for time-dependent Wilson loops. We find that in the S5-rotating case there appears to be no direct open-string duals for the Minkowskian Wilson loops, and their expectation values should be obtained by analytic continuation from the Euclidean-space results. In the Euclidean case, we determine the dependence of the ``quark - anti-quark'' potential on the rotation parameter, both at weak coupling (i.e. in the 1-loop perturbative SYM theory) and at strong coupling (i.e. in the classical string theory in AdS5 x S5).

description: Methods to quantify predictability properties of atmospheric flows are proposed. The ``Extended Self Similarity'' (ESS) technique, recently employed in turbulence data analysis, is used to characterize predictability properties at short and long times. We apply our methods to the low-order atmospheric model of Lorenz (1980). We also investigate how initialization procedures that eliminate gravity waves from the model dynamics influence predictability properties.

Exact Renormalization of Wave Functionals yields Continuous MERA

description: The exact renormalization group (ERG) is a powerful tool for understanding the formal properties of field theories. By adapting generalized ERG schemes to the flow of wavefunctionals, we obtain a large class of continuous unitary networks, a special case of which includes a class of Gaussian continuous Multi-scale Renormalization Ansatzes (cMERAs). The novel feature of these generalized wavefunctional ERG schemes is allowing for modifications of the dispersion relation, which drastically changes the entanglement structure of the ultraviolet states. Through our construction, we demonstrate that cMERA can be derived from a more fundamental "microscopic" principle, which amounts to the usual RG principle of path integral independence, suitably adapted to quantum states of the field theory. The establishment of such a principle may provide a path forward for exploring cMERA beyond the free field regime, and for understanding the nature of entanglement renormalization intrinsically in the continuum.

Tibetan Communities in Transition: An Ethnographic Study of State-run Formal Education and Social Change

description: State-run formal schools were established as novel educational institutions throughout the Tibetan regions in China in the 1950s. Based on a fifteen-month anthropological fieldwork in a Tibetan region in A mdo, this dissertation examines the impact of formal education on social change in Tibetan communities. Through a comprehensive analysis of: Chinese government policies; economic development; Tibetan educational models and practices; personal narratives from Tibetans of different generations; and traditional rituals, this dissertation investigates the role of formal education in Tibetan society. I argue that formal education is a main factor spurring social change in Tibetan communities. Education, through established formal institutions, integrates Tibetan communities into the national society of China, bringing close contact with non-Tibetan outsiders and binding students together with shared values and goals. This study shows that formal education is a legitimating venue through which Tibetans seek socioeconomic benefits and, as a result, education creates diversification in livelihoods and influences the dynamics of family structure, marriage patterns, identity, gender relations, and labor divisions.

Nonholonomic Mapping Principle for Classical Mechanics in Spaces with Curvature and Torsion. New Covariant Conservation Law for Energy-Momentum Tensor
Creators: name: Kleinert, Hagen
Publisher: name: arXiv
Year: 1998
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The lecture explains the geometric basis for the recently-discovered nonholonomic mapping principle which specifies certain laws of nature in spacetimes with curvature and torsion from those in flat spacetime, thus replacing and extending Einstein's equivalence principle. An important consequence is a new action principle for determining the equation of motion of a free spinless point particle in such spacetimes. Surprisingly, this equation contains a torsion force, although the action involves only the metric. This force changes geodesic into autoparallel trajectories, which are a direct manifestation of inertia. The geometric origin of the torsion force is a closure failure of parallelograms. The torsion force changes the covariant conservation law of the energy-momentum tensor whose new form is derived.

description: Critical servers can be secured against distributed denial of service (DDoS) attacks using proof of work (PoW) systems assisted by an Artificial Intelligence (AI) that learns contextual network request patterns. In this work, we introduce CAPoW, a context-aware anti-DDoS framework that injects latency adaptively during communication by utilizing context-aware PoW puzzles. In CAPoW, a security professional can define relevant request context attributes which can be learned by the AI system. These contextual attributes can include information about the user request, such as IP address, time, flow-level information, etc., and are utilized to generate a contextual score for incoming requests that influence the hardness of a PoW puzzle. These puzzles need to be solved by a user before the server begins to process their request. Solving puzzles slow down the volume of incoming adversarial requests. Additionally, the framework compels the adversary to incur a cost per request, hence making it expensive for an adversary to prolong a DDoS attack. We include the theoretical foundations of the CAPoW framework along with a description of its implementation and evaluation.

Fertility decline in West Java : analysis and interpretation

Subjects: subject: Fertility, Human Indonesia Jawa Barat

description: The aim of the study is to analyse and interpret fertility decline in West Java. While empirical data derived from various surveys and censuses are used for the analysis, the available literature supplements information for the interpretation. It is argued that the geographic setting and sociocultural environment of West Java explain the relatively high level of fertility for the province. Consistent fertility decline and significant socioeconomic differentials in fertility have been found for West Java. Yet, fertility levels of the province have always been the highest among those of the provinces of Java and Bali. The study suggests that changes and differences in a number of intermediate variables (such as age at marriage and contraceptive practice) have been largely responsible for the observed phenomena. Examination of the major components of the crude birth rate (CBR) indicates that age structure and the proportion of the population in childbearing ages have hindered the CBR decline. In contrast, marital status and marital fertility have been strongly conducive to the decline. The study also suggests that fertility decline in West Java has occurred in the presence of significant improvement in socioeconomic development.

description: The magnetic properties of metal-organic complexes are strongly influenced by conformational changes in the ligand. The flexibility of Fe-tetra-pyridyl-porphyrin molecules leads to different adsorption configurations on a Au(111) surface. By combining low-temperature scanning tunneling spectroscopy and atomic force microscopy, we resolve a correlation of the molecular configuration with different spin states and magnitudes of magnetic anisotropy. When the macrocycle exhibits a laterally-undistorted saddle shape, the molecules lie in a S=1 state with axial anisotropy arising from a square-planar ligand field. If the symmetry in the molecular ligand field is reduced by a lateral distortion of the molecule, we find a finite contribution of transverse anisotropy. Some of the distorted molecules lie in a S=2 state, again exhibiting substantial transverse anisotropy.
