description: Tracy and Widom have evaluated the cumulative distribution of the largest eigenvalue for the finite and scaled infinite GUE in terms of a PIV and PII transcendent respectively. We generalise these results to the evaluation of $\tilde{E}_N(λ;a) := \Big < \prod_{l=1}^N χ_{(-\infty, λ]}^{(l)} (λ- λ_l)^a \Big>$, where $ χ_{(-\infty, λ]}^{(l)} = 1$ for $λ_l \in (-\infty, λ]$ and $ χ_{(-\infty, λ]}^{(l)} = 0$ otherwise, and the average is with respect to the joint eigenvalue distribution of the GUE, as well as to the evaluation of $F_N(λ;a) := \Big < \prod_{l=1}^N (λ- λ_l)^a \Big >$. Of particular interest are $\tilde{E}_N(λ;2)$ and $F_N(λ;2)$, and their scaled limits, which give the distribution of the largest eigenvalue and the density respectively. Our results are obtained by applying the Okamoto $τ$-function theory of PIV and PII, for which we give a self contained presentation based on the recent work of Noumi and Yamada. We point out that the same approach can be used to study the quantities $\tilde{E}_N(λ;a)$ and $F_N(λ;a)$ for the other classical matrix ensembles.

description: Motivation:
Unsupervised learning approaches are frequently employed to identify patient subgroups and biomarkers such as disease-associated genes. In particular, biclustering is a powerful technique often used with expression data to cluster genes along with patients. However, the genes forming biclusters are often not functionally or mechanistically related, complicating interpretation of the results. To alleviate this, we propose to restrict biclusters to genes connected in molecular interaction networks to impose functional relation and to enhance interpretability.

Results:
We developed the network-constrained biclustering approach BiGAnts. Our aim to maximize the difference in expression between two subgroups of patients under the constraint that the selected genes are connected in a molecular interaction network, hence forming an interpretable \textit{de novo} pathway.
Analyses a non-small cell lung carcinoma and breast cancer demonstrate that BiGAnts clusters patients in agreement with known cancer subtypes while discovering subnetworks of genes pointing to functional differences between these subtypes. Furthermore, we show that BiGAnts differentiates between a high and low load of tumour-infiltrating leukocytes while identifying subnetworks related to immune cell function. BiGAnts, which is also robust to noise and batch-effects, thus serves as a powerful new systems medicine tool to stratify patients while elucidating the responsible disease mechanism.

description: This thesis analyzes the nature of manufacturing employment in Java. The term of "manufacturing workers" in this study, refers to those who worked in the manufacturing sector during the pre-enumeration week. Manufacturing sector in Indonesia has grown rapidly in recent years. However, Indonesia, also Java is considered still in the threshold of industrialization. The pattern of labour force participation, as well as unemployment in the working population does not lie beyond what are usually found in developing countries in general. The characteristics of the manufacturing workers in Java are virtually the same as those of the total population in Java.. The occupational distribution of manufacturing workers in Java is what one might expect from a country with such a low educational background. The manufacturing employment in terms of its rate and utilization varies among provinces associated with differences in socio-demographic, economic and cultural of the regions.

description: The best pair problem aims to find a pair of points that minimize the distance between two disjoint sets. In this paper, we formulate the classical robust principal component analysis (RPCA) as the best pair; which was not considered before. We design an accelerated proximal gradient scheme to solve it, for which we show global convergence, as well as the local linear rate. Our extensive numerical experiments on both real and synthetic data suggest that the algorithm outperforms relevant baseline algorithms in the literature.

description: A new method for predicting inflationary cosmological perturbations, based on the Wentzel-Kramers-Brillouin (WKB) approximation, is presented. A general expression for the WKB scalar and tensor power spectra is derived. The main advantage of the new scheme of approximation is that it is valid even if the slow-roll conditions are violated. The method is applied to power-law inflation, which allows a comparison with an exact result. It is demonstrated that the WKB approximation predicts the spectral indices exactly and the amplitude with an error lower than 10%, even in regimes far from scale-invariance. The new method of approximation is also applied to a situation where the slow-roll conditions hold. It is shown that the result obtained bears close resemblance with the standard slow-roll calculation. Finally, some possible improvements are briefly mentioned.

description: Clouds affected by solar eclipses could influence the reflection of sunlight back into space and might change local precipitation patterns. Satellite cloud retrievals have so far not taken into account the lunar shadow, hindering a reliable spaceborne assessment of the eclipse-induced cloud evolution. Here we use satellite cloud measurements during three solar eclipses between 2005 and 2016 that have been corrected for the partial lunar shadow together with large-eddy simulations to analyze the eclipse-induced cloud evolution. Our corrected data reveal that, over cooling land surfaces, shallow cumulus clouds start to disappear at very small solar obscurations. Our simulations explain that the cloud response was delayed and was initiated at even smaller solar obscurations. We demonstrate that neglecting the disappearance of clouds during a solar eclipse could lead to a considerable overestimation of the eclipse-related reduction of net incoming solar radiation. These findings should spur cloud model simulations of the direct consequences of sunlight-intercepting geoengineering proposals, for which our results serve as a unique benchmark.

description: How to make compatible both boundary and gauge conditions for generally covariant theories using the gauge symmetry generated by first class constraints is studied. This approach employs finite gauge transformations in contrast with previous works which use infinitesimal ones. Two kinds of variational principles are taken into account; the first one features non-gauge-invariant actions whereas the second includes fully gauge-invariant actions. Furthermore, it is shown that it is possible to rewrite fully gauge-invariant actions featuring first class constraints quadratic in the momenta into first class constraints linear in the momenta (and homogeneous in some cases) due to the full gauge invariance of their actions. This shows that the gauge symmetry present in generally covariant theories having first class constraints quadratic in the momenta is not of a different kind with respect to the one of theories with first class constraints linear in the momenta if fully gauge-invariant actions are taken into account for the former theories. These ideas are implemented for the parametrized relativistic free particle, parametrized harmonic oscillator, and the SL(2,R) model.

The symmetry-breaking scale of the texture controls the particle hierarchy between the two branes. The TeV-scale particles are confined to the negative-tension brane where the observer sees gravity as essentially four dimensional. The effect of massive Kaluza-Klein gravitons is suppressed.

description: The most common method to measure direct current high voltage (HV) down to the ppm-level is to use resistive high-voltage dividers. Such devices scale the HV into a range where it can be compared with precision digital voltmeters to reference voltages sources, which can be traced back to Josephson voltage standards. So far the calibration of the scale factors of HV dividers for voltages above 1~kV could only be done at metrology institutes and sometimes involves round-robin tests among several institutions to get reliable results. Here we present a novel absolute calibration method based on the measurement of a differential scale factor, which can be performed with commercial equipment and outside metrology institutes. We demonstrate that reproducible measurements up to 35~kV can be performed with relative uncertainties below $1\cdot10^{-6}$. This method is not restricted to metrology institutes and offers the possibility to determine the linearity of high-voltage dividers for a wide range of applications.

Radiative transfer of hydrogen lines from supernova remnant shock waves: contributions of 2s-state hydrogen atoms

Publisher: name: arXiv
Year: 2019
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Radiative transfer in hydrogen lines in supernova remnant (SNR) shock waves is studied taking into account the population of the hydrogen atom 2s-state. Measurements of Balmer line emission, especially of H~$α$, are often relied upon to derive physical conditions in the SNR shock. On the other hand, Lyman series photons, especially Ly~$β$, are mostly absorbed by upstream hydrogen atoms. As a result, atoms are excited to the 3p state, and then emit H~$α$ by the spontaneous transition from 3p to 2s. Thus, the nature of H~$α$ depends on how many Ly~$β$ photons are converted to H~$α$ photons. Moreover, the Balmer lines can be scattered by the 2s-state hydrogen atoms, which are excited not only by collisional excitation but also by the Lyman-Balmer conversion. It is shown for example that the H~$α$ photons are scattered if the shock propagates into an H~$_{\rm I}$ cloud with a density of $\sim30~{\rm cm^{-3}}$ and a size of $\sim 1$~pc. We find that the line profile of H~$α$ becomes asymmetric resulting from the difference between line centre frequencies among the transitions from 3s to 2p, from 3p to 2s and from 3d to 2p. We also find that the broad-to-narrow ratio of H~$α$, which is often used to estimate the ion-electron temperature equilibrium, varies at most $\simeq 10$ per cent depending on the ionization degree of the upstream medium because of incomplete conversion of Lyman lines to Balmer lines.

description: In this review we examine the dynamics and gravitational wave detectability of rotating strained neutron stars. The discussion is divided into two halves: triaxial stars, and precessing stars. We summarise recent work on how crustal strains and magnetic fields can sustain triaxiality, and suggest that Magnus forces connected with pinned superfluid vortices might contribute to deformation also. The conclusions that could be drawn following the successful gravitational wave detection of a triaxial star are discussed, and areas requiring further study identified. The latest ideas regarding free precession are then outlined, and the recent suggestion of Middleditch et al (2000a,b) that the remnant of SN1987A contains a freely precessing star, spinning-down by gravitational wave energy loss, is examined critically. We describe what we would learn about neutron stars should the gravitational wave detectors prove this hypothesis to be correct.

description: Spiral structure can contribute significantly to a galaxy's luminosity. However, only rarely are proper photometric models of spiral arms used in decompositions. As we show in the previous work, including the spirals as a separate component in a photometric model of a galaxy would both allow to obtain their structural parameters, and reduce the systematic errors in estimating the parameters of other components. Doing so in different wavebands, one can explore how their properties vary with the wavelength. In this paper, second in this series, we perform decomposition of M 51 in 17 bands, from the far UV to far IR, using imaging from the DustPedia project. We use the same 2D photometric model of spiral structure where each arm is modelled independently. The complex and asymmetric spiral structure in M 51 is reproduced relatively well with our model. We analyze the differences between models with and without spiral arms, and investigate how the fit parameters change with wavelength. In particular, we find that the spiral arms demonstrate the largest width in the optical, whereas their contribution to the galaxy luminosity is most significant in the UV. The disk central intensity drops by a factor of 1.25--3 and its exponential scale changes by 5--10\% when spiral arms are included, depending on wavelength. Taking into account the full light distribution across the arms, we do not observe the signs of a long-lived density wave in the spiral pattern of M 51 as a whole.

description: Data is arguably the most valuable asset of the modern world. In this era, the success of any data-intensive solution relies on the quality of data that drives it. Among vast amount of data that are captured, managed, and analyzed everyday, geospatial data are one of the most interesting class of data that hold geographical information of real-world phenomena and can be visualized as digital maps. Geo-spatial data is the source of many enterprise solutions that provide local information and insights. In order to increase the quality of such solutions, companies continuously aggregate geospatial datasets from various sources. However, lack of a global standard model for geospatial datasets makes the task of merging and integrating datasets difficult and error-prone. Traditionally, domain experts manually validate the data integration process by merging new data sources and/or new versions of previous data against conflicts and other requirement violations. However, this approach is not scalable and is hinder toward rapid release, when dealing with frequently changing big datasets. Thus more automated approaches with limited interaction with domain experts is required. As a first step to tackle this problem, in this paper, we leverage Information Retrieval (IR) and geospatial search techniques to propose a systematic and automated conflict identification approach. To evaluate our approach, we conduct a case study in which we measure the accuracy of our approach in several real-world scenarios and we interview with software developers at Localintel Inc. (our industry partner) to get their feedbacks.

description: We consider the thermodynamic properties of $(d+1)$-dimensional spacetimes with NUT charges. Such spacetimes are asymptotically locally anti de Sitter (or flat), with non-trivial topology in their spatial sections, and can have fixed point sets of the Euclidean time symmetry that are either $(d-1)$-dimensional (called "bolts") or of lower dimensionality (pure "NUTs"). We compute the free energy, conserved mass, and entropy for 4, 6, 8 and 10 dimensions for each, using both Noether charge methods and the AdS/CFT-inspired counterterm approach. We then generalize these results to arbitrary dimensionality. We find in $4k+2$ dimensions that there are no regions in parameter space in the pure NUT case for which the entropy and specific heat are both positive, and so all such spacetimes are thermodynamically unstable. For the pure NUT case in $4k$ dimensions a region of stability exists in parameter space that decreases in size with increasing dimensionality. All bolt cases have some region of parameter space for which thermodynamic stability can be realized.

description: We experimentally demonstrate the phenomenon of electroosmotic dipole flow that occurs around a localized surface charge region under the application of an external electric field in a Hele-Shaw cell. We use localized deposition of polyelectrolytes to create well-controlled surface charge variations, and show that for a disk-shaped spot, the internal pressure distribution that arises, results in uniform flow within the spot and dipole flow around it. We further demonstrate the superposition of surface charge spots to create complex flow patterns, without the use of physical walls.

description: While diversity has become a debated issue in design, very little research exists on positive use-cases for diversity beyond scholarly criticism. The current work addresses this gap through the case of a diversity-aware chatbot, exploring what benefits a diversity-aware chatbot could bring to people and how do people interpret diversity when being presented with it. In this paper, we motivate a Q&A chatbot as a technology probe and deploy it in two student communities within a study. During the study, we collected contextual data on people's expectations and perceptions when presented with diversity during the study. Our key findings show that people seek out others with shared niche interests, or their search is driven by exploration and inspiration when presented with diversity. Although interacting with chatbots is limited, participants found the engagement novel and interesting to motivate future research.

description: In this paper, we study the problem of computing a Principal Component Analysis of data affected by Poisson noise. We assume samples are drawn from independent Poisson distributions. We want to estimate principle components of a fixed transformation of the latent Poisson means. Our motivating example is microbiome data, though the methods apply to many other situations. We develop a semiparametric approach to correct the bias of variance estimators, both for untransformed and transformed (with particular attention to log-transformation) Poisson means. Furthermore, we incorporate methods for correcting different exposure or sequencing depth in the data. In addition to identifying the principal components, we also address the non-trivial problem of computing the principal scores in this semiparametric framework. Most previous approaches tend to take a more parametric line. For example the Poisson-log-normal (PLN) model, approach. We compare our method with the PLN approach and find that our method is better at identifying the main principal components of the latent log-transformed Poisson means, and as a further major advantage, takes far less time to compute. Comparing methods on real data, we see that our method also appears to be more robust to outliers than the parametric method.

The negotiation of circumstance : New Zealand women artists, c.1890-1914

Subjects: subject: Women artists New Zealand

description: As a study of the emergence of women artists in New Zealand, c.1890-l9l4, this thesis is also a study in the ideological and material basis of Cultural production and Cultural life in the colony. It is argued here that during this period, the imperial relationship created an environment in the colony which both empowered and disabled women as Artists. The material conditions of life and work in the Art world, the way the recruitment, practice and profession of Artists was organized, enabled women to compete on terms of near equality with men. Further, the congruence that existed through ideology between Woman and Artist, meant women could accept themselves, and be accepted by others, as Artists. Art was within their sphere. However, colonial society necessitated training as a professional, in Europe and in Europe the circumstances were different. The advantageous and enabling circumstances did not exist in the same way in the Art circles of European cities. In these environments, the ideology and practice of Art differentiated more markedly between men and women. Colonial women were doubly disabled in Europe, once by their colonial origin and then again by gender. Women existed as Artists most easily within enclaves in Europe where the conditions, customs and methods of work most closely replicated those of their colonial homeland. This led however, led women away from places of influence and into marginalised expatriate networks or into perpetual studenthood. The world of New Zealand's painters was one of complex, and contradictory or ambiguous possibilities at the level of both ideology and material conditions. The model of oppression-and-resistance usually employed in women's history cannot easily deal with this, and make their lives comprehensible. Concepts must be developed to allow for the more complex effects of the way power operates both productively and repressively. The formulation of the 'negotiation of circumstance' has allowed this complexity to emerge.
Perfectly nested loops : communication and memory reuse for do-across loops

Subjects: subject: Parallel programming (Computer science)

description: The expression of problem solutions in a serial form has distinct advantages over parallel implementations from the programmer's point of view: 1. The thought process involved in constructing a program solution is more intuitive. 2. The language itself, (eg FORTRAN), can be standard across a large range of platforms. Although often under one paradigm one of the above may be true, both are seldom true simultaneously. Frequently programs which are used to solve scientific or engineering problems display a high degree of repetitiveness. This regular and repetitive nature has a high degree of inherent parallelism. The extraction and exploitation of parallelism from program structures such as loop nests has been extensively studied. A set of fundamental transforms form a basis for extracting parallelism. Some of these techniques are: data space transforms such as array expansion and scalar expansion, loop transformations such as skewing, reversal, interchange and tiling. Other methods such as ChainBased Scheduling rely on these techniques. In this thesis we examine a perfectly nested set of loops, in which some or all of those loops are Do-ACROSS loops. The loop nest is partitioned by tiling and the resulting subsets of iterations are not independent. This gives rise to several issues: 1. Communication:- what messages must be sent and what they actually contain. 2. Data Distribution:- what data is needed by which processor and what data must be shared. 3. Memory Reuse:- can memory be reused during execution, if so under what conditions. These issues are covered and answered by techniques presented in this thesis.

description: Integrated nonlinear optical devices play an important role in modern optical communications. However, conventional on-chip optical devices with homogeneous or periodic translation dimensions generally have limited bandwidth when applied to nonlinear optical applications. Up today, there lacks a general method to design compact nonlinear optical devices over a broadband continuous frequency range. In this work, we propose a general strategy based on transformation optics (TO) to design curved accelerating waveguides (CAWs) with spatially gradient curvatures able to achieve broadband nonlinear frequency conversion on chip. Through rigorous analytical calculation, we show that increasing the acceleration (i.e. gradient in the waveguide curvature) broadens the output signal spectrum in the nonlinear process. In the experiment, we take the sum-frequency generation for infrared signal upconversion (SFG-ISU) as the example and fabricated a variety of CAWs using thin-film lithium niobate on insulator (LNOI). Efficient SFG is observed over a broadband continuous spectrum. Our conformal mapping approach offers a platform for various nonlinear optical processes and works in any frequency range, including visible, infrared and terahertz bands. Apart from LNOI, our approach is also compatible with other nonlinear materials, such as silicon, silicon nitride and chalcogenide glasses etc.

Year: 2001
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We describe a new interactive database (GRDB) of geometric objects in the general area of differential geometry. Database objects include, but are not restricted to, exact solutions of Einstein's field equations. GRDB is designed for researchers (and teachers) in applied mathematics, physics and related fields. The flexible search environment allows the database to be useful over a wide spectrum of interests, for example, from practical considerations of neutron star models in astrophysics to abstract space-time classification schemes. The database is built using a modular and object-oriented design and uses several Java technologies (e.g. Applets, Servlets, JDBC). These are platform-independent and well adapted for applications developed to run over the World Wide Web. GRDB is accompanied by a virtual calculator (GRTensorJ), a graphical user interface to the computer algebra system GRTensorII used to perform online coordinate, tetrad or basis calculations. The highly interactive nature of GRDB allows for systematic internal self-checking and a minimization of the required internal records.

description: The interpretation of nanoplasmonic effects on molecular properties, such as metal-enhanced absorption or fluorescence, typically assumes a fully coherent picture (in the quantum-mechanical sense) of the phenomena. Yet, there may be conditions where the coherent picture breaks down, and decoherence effect should be accounted for. Using a state-of-the-art multiscale model approach able to include environment-induced dephasing, here we show that metal nanoparticle effects on the light absorption by a nearby molecule is strongly affected (even qualitatively, i.e., suppression vs enhancement) by molecular electronic decoherence. The present work shows that decoherence can be thought as a further design element of molecular nanoplasmonic systems.

description: Mortality rates in developing countries have shown a rapidly declining trend since the end of World War II. Countries like Malaysia, Taiwan, Mauritius, Jamaica, and Mexico have increased life expectancy at birth at an average of over a year annually between the 1940's and 1960's (Gwatkin, 1980:616). There appeared to be special causes; probably due to control of endemic disease. Many developing countries have recorded life expectancy gains three or more times as great as those achieved in Western Europe at a comparable stage in its mortality transition (Gwatkin, 1980:616).

description: Radar-based road user classification is an important yet still challenging task towards autonomous driving applications. The resolution of conventional automotive radar sensors results in a sparse data representation which is tough to recover by subsequent signal processing. In this article, classifier ensembles originating from a one-vs-one binarization paradigm are enriched by one-vs-all correction classifiers. They are utilized to efficiently classify individual traffic participants and also identify hidden object classes which have not been presented to the classifiers during training. For each classifier of the ensemble an individual feature set is determined from a total set of 98 features. Thereby, the overall classification performance can be improved when compared to previous methods and, additionally, novel classes can be identified much more accurately. Furthermore, the proposed structure allows to give new insights in the importance of features for the recognition of individual classes which is crucial for the development of new algorithms and sensor requirements.
