Publisher: name: Columbia University
Year: 2010
Subjects: Computer science

description: The world needs special-purpose accelerators to meet future constraints on computation and power consumption. Choosing appropriate accelerator architectures is a key challenge. In this work, we present a pintool designed to help evaluate the potential benefit of accelerating a particular function. Our tool gathers cross-procedural data usage patterns, including implicit dependencies not captured by arguments and return values. We then use this data to characterize the limits of hardware procedural acceleration imposed by on-chip communication and storage systems. Through an understanding the bottlenecks in future accelerator-based systems we will focus future research on the most performance-critical regions of the design. Accelerator designers will also find our tool useful for selecting which regions of their application to accelerate.

description: As was demonstrated in earlier studies, turbulence can result in a negative contribution to the effective mean magnetic pressure, which, in turn, can cause a large-scale instability. In this study, hydromagnetic mean-field modelling is performed for an isothermally stratified layer in the presence of a horizontal magnetic field. The negative effective magnetic pressure instability (NEMPI) is comprehensively investigated. It is shown that, if the effect of turbulence on the mean magnetic tension force vanishes, which is consistent with results from direct numerical simulations of forced turbulence, the fastest growing eigenmodes of NEMPI are two-dimensional. The growth rate is found to depend on a parameter beta_* characterizing the turbulent contribution of the effective mean magnetic pressure for moderately strong mean magnetic fields. A fit formula is proposed that gives the growth rate as a function of turbulent kinematic viscosity, turbulent magnetic diffusivity, the density scale height, and the parameter beta_*. The strength of the imposed magnetic field does not explicitly enter provided the location of the vertical boundaries are chosen such that the maximum of the eigenmode of NEMPI fits into the domain. The formation of sunspots and solar active regions is discussed as possible applications of NEMPI.

Imagery of female Daoists in Tang and Song poetry
Creators: name: Liu, Yang
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation involves a literary study that aims to understand the lives of female Daoists who lived from the eighth to the twelfth centuries in China. Together with an examination of the various individual qualities manifested in their poetry, this study includes related historical background, biographical information and a discussion of the aspirations and cultural life of the female clergy. Unlike some of the previous scholarship that has examined Daoist deities and mythical figures described in hagiographical texts and literary creations, or on topics such as the Divine Mother of the West and miscellaneous goddesses and fairies, this work takes the perspective of examining female Daoists as historical persons who lived in real Daoist convents. As such, this work concentrates on the assorted images of female Daoists presented in their own poetic works, including those of Yu Xuanji, Li Ye, Yuan Chun, Cao Wenyi and Sun Bu-er. Furthermore, this thesis also examines poetic works about female Daoists written by male literati from both inside and outside the Daoist religion. I do this in order to illustrate how elite men, the group with whom female Daoists interacted most frequently, appreciated and portrayed these special women and their poetry. I believe that a study of their works on Daoist women will not only allow us a better understanding of the nature and characters of female Daoists, but will also contribute to our knowledge of intellectual life in Tang and Song society. An investigation of their varied representation at different historical junctures illustrates the multifarious images of Tang Daoist nuns and the strong commitment that the Song Daoist priestesses made to their religious enterprise, as well as the divergent perspectives and responses that the male intellectuals of the time had for this unique group of women.

description: Observations of high-redshift supernovae (SNe) open a novel opportunity to study the massive star population in the early Universe. We study the detectability of superluminous SNe with upcoming optical and near-infrared (NIR) surveys. Our calculations are based on the cosmic star formation history, the SN occurence rate, the characteristic colour and the light curve of the SNe that are all calibrated by available observations. We show that 15-150 SNe up to z ~ 4 will be discovered by the proposed Subaru/Hyper Suprime-Cam deep survey: 30 deg^2 survey with 24.5 AB mag depth in z-band for 3 months. With its ultra-deep layer (3.5 deg^2 with 25.6 AB mag depth in z-band for 4 months), the highest redshift can be extended to z ~ 5. We further explore the detectability by upcoming NIR survey utilizing future satellites such as Euclid, WFIRST, and WISH. The wide-field NIR surveys are very efficient to detect high-redshift SNe. With a hypothetical deep NIR survey for 100 deg^2 with 26 AB mag depth at 1-4 um, at least ~ 50 SNe will be discovered at z>3 in half a year. The number of the detected SNe can place a strong constraint on the stellar initial mass function or its slope especially at the high-mass end. Superluminous SNe at high redshifts can be distinguished from other types of SNe by the long time-scale of their light curves in the observer's frame, the optical colours redder than other core-collapse SNe and the NIR colours redder than any other types of SNe.

description: We present MINESTRONE, a novel architecture that integrates static analysis, dynamic confinement, and code diversification techniques to enable the identification, mitigation and containment of a large class of software vulnerabilities in third-party software. Our initial focus is on software written in C and C++; however, many of our techniques are equally applicable to binary-only environments (but are not always as efficient or as effective) and for vulnerabilities that are not specific to these languages. Our system seeks to enable the immediate deployment of new software {e.g., a new release of an open-source project) and the protection of already deployed (legacy) software by transparently inserting extensive security instrumentation, while leveraging concurrent program analysis, potentially aided by runtime data gleaned from profiling actual use of the software, to gradually reduce the performance cost of the instrumentation by allowing selective removal or refinement. Artificial diversification techniques are used both as confinement mechanisms and for fault-tolerance purposes. To minimize the performance impact, we are leveraging multi-core hardware or (when unavailable) remote servers that enable quick identification of likely compromise. To cover the widest possible range of systems, we require no specific hardware or operating system features, although we intend to take advantage of such features where available to improve both runtime performance and vulnerability coverage.

A Central Excess of Stripped-Envelope Supernovae within Disturbed Galaxies

description: This paper presents an analysis of core-collapse supernova distributions in isolated and interacting host galaxies, paying close attention to the selection effects involved in conducting host galaxy supernova studies. When taking into account all of the selection effects within our host galaxy sample, we draw the following conclusions: i) Within interacting, or 'disturbed', systems there is a real, and statistically significant, increase in the fraction of stripped-envelope supernovae in the central regions. A discussion into what may cause this increased fraction, compared to the more common type IIP supernovae, and type II supernovae without sub-classifications, is presented. Selection effects are shown not to drive this result, and so we propose that this study provides direct evidence for a high-mass weighted initial mass function within the central regions of disturbed galaxies. ii) Within 'undisturbed' spiral galaxies the radial distribution of type Ib and type Ic supernovae is statistically very different, with the latter showing a more centrally concentrated distribution. This could be driven by metallicity gradients in these undisturbed galaxies, or radial variations in other properties (binarity or stellar rotation) driving envelope loss in progenitor stars. This result is not found in 'disturbed' systems, where the distributions of type Ib and Ic supernovae are consistent.

description: We show that the evolution of magnetic fields in a primordial plasma, filled with Standard Model particles, at temperatures T > 10 MeV is strongly affected by the quantum chiral anomaly -- an effect that has been neglected previously. Although reactions equilibrating left and right-chiral electrons are in deep thermal equilibrium for T < 80 TeV, an asymmetry between these particle develops in the presence of strong magnetic fields. This results in magnetic helicity transfer from shorter to longer scales. This also leads to an effective generation of lepton asymmetry that may survive in the plasma down to temperatures T ~ 10 MeV, which may strongly affect many processes in the early Universe. Although we report our results for the Standard Model, they are likely to play an important role also in its extensions.

description: Dynamic taint analysis (DTA) is a technique used for tracking information flow by propagating taint propagation across memory locations during program execution. Most implementations of DTA are based on dynamic binary instrumentation (DBI) frameworks or whole-system emulators/virtual machine monitors. The boundary of information tracking with DBI frameworks is a single process, while system emulators can cover a host, including the OS. Using system emulators, it may be possible to consider taint propagation across multiple processes executing locally, within the emulator. However, there is an increasing need for tracking information flow across single-system boundaries and across the whole enterprise. We describe a proof-of-concept architecture for tracking multiple mixed-information flows among several processes across a distributed enterprise. Our DTA tool is based on PIN, a DBI framework by Intel, and the concatenated DTA processing is realized with per-host flow managers. We have tested our prototype with typical enterprise applications. As a motivating example, we track information leakage due to a SQL injection attack from a web-based database server query. Our work is of an exploratory nature, aiming to expose our early findings and identify areas where additional research is needed in improving usability and performance.
Competitively Evolving Decision Trees Against Fixed Training Cases for Natural Language Processing

description: Competitive fitness functions can generate performance superior to absolute fitness functions [Angelineand Pollack 1993], [Hillis 1992]. This chapter describes a method by which competition can be implemented when training over a fixed (static) set of examples. Since new training cases cannot be generated by mutation or crossover, the probabilistic frequencies by which individual training cases are selected competitively adapt. We evolve decision trees for the problem of word sense disambiguation. The decision trees contain embedded bit strings; bit string crossover is intermingled with subtree-swapping. To approach the problem of overlearning, we have implemented a fitness penalty function specialized for decision trees which is dependent on the partition of the set of training cases implied by a decision tree.

Characterizing Self-healing Software Systems

Publisher: name: Columbia University
Year: 2007
Subjects: Computer science

description: The introduction of self-healing capabilities to software systems could offer a way to alter the current, unfavorable imbalance in the software security arms race. Consequently, self-healing software systems have emerged as a research area of particular interest in recent years. Motivated by the inability of traditional techniques to guarantee software integrity and availability, especially against motivated human adversaries, self-healing approaches are meant to complement existing approaches to security. In this paper, we provide a first attempt to characterize self-healing software systems by surveying some of the existing work in the field. We focus on systems that effect structural changes to the software under protection, as opposed to block-level system reconfiguration. Our goal is to begin mapping the space of software self-healing capabilities. We believe this to be a necessary first step in exploring the boundaries of the research space and understanding the possibilities that such systems enable, as well as determining the risks and limitations inherent in automatic-reaction schemes.

description: We demonstrate an ultrafast reversible modulation of resonant terahertz (THz) response in strongly photoexcited metamaterials. The transient spectral-temporal response of the dipole transition ~1.6 THz exhibits a distinct non-monotonic variation as a function of pump fluence. The transition energy shift, strength, spectral width and density-dependent ultrafast relaxation manifest a remarkable re-emergence of the resonances after initial quenching. Our simulation, incorporating the first-order diffraction from the photoinduced transient grating, reproduces the salient features, providing a new avenue for designing nonlinear and frequency-agile THz modulators.

description: This study analyses the interplay of migration narratives as they traverse the media, politics, and policy-making arenas in Spain. More specifically, it examines how narratives on migration, circulate within the mass media and the political debate and subsequently influence policy-making processes. Building on the 'narrative policy framework' (Jones and McBeth 2010), the 'communicative' and 'coordinative' spheres of policy-making (Schmidt 2008) and the distinction between 'lay' and 'technocratic' styles of narratives (Boswell and Smellie 2023), this study tries to elucidate the dynamics of narrative circulation by focusing on three case studies: a) the European migration crisis in 2015 and the EU relocation scheme; b) the Ukrainian refugees after the start of the war in 2022; and c) the crisis of the rescue boat Aquarius in the Mediterranean in 2018. Results point to a common pattern of decoupling between the communicative sphere (media and political narratives) and the coordinative sphere (policy-making narratives) in the three cases. Yet, this does not mean that policy-making on migration is not affected by narratives. However, these are not so related to the specific events, but to the master narratives that have been present in all the governments (be them left-wing or centre-right oriented) increasingly influenced by a securitarian turn. On the other hand, there is a trend to produce more technocratic narratives based on facts as we come closer to the policy-making sphere and we move away from the media debates which are more dominated by lay narratives oriented to the wider public.

description: We describe the mbuf tag API, a mechanism for tagging data as they flow through the network stack. Originally introduced in OpenBSD, mbuf tags were initially intended for use by the IPsec stack. The API has matured enough to be used by several other kernel components, and formed the basis for the FreeBSD mbuf tags. We present the API, discuss its various uses in the OpenBSD network stack, and describe some plans for future work. Our goal is to demonstrate the flexibility of this relatively simple mechanism and expose it to other kernel developers.

description: Energetic gamma rays (GeV to TeV photon energy) have been detected toward several supernova remnants (SNR) associated with molecular clouds. If the gamma rays are produced mainly by hadronic processes rather than leptonic processes like bremsstrahlung, then the flux of energetic cosmic ray (CR) nuclei (>1 GeV) required to produce the gamma rays can be inferred at the site where the particles are accelerated in SNR shocks. It is of great interest to understand the acceleration of the CR of lower energy (<1 GeV) accompanying the energetic component. These particles of lower energy are most effective in ionizing interstellar gas, leaving an observable imprint on the interstellar ion chemistry. A correlation of energetic gamma radiation with enhanced interstellar ionization can thus support the hadronic origin of the gamma rays and constrain the acceleration of ionizing CR in SNR. We propose a method to test the hadronic origin of GeV gamma rays from SNR associated with a molecular cloud. We use observational gamma ray data for each of these SNR known, modeling the observations to obtain the underlying proton spectrum assuming that the gamma rays are produced by pion decay. Assuming that the acceleration mechanism does not only produce high energy protons, but also low energy protons, this proton spectrum at the source is then used to calculate the ionization rate of the molecular cloud. Ionized molecular hydrogen triggers a chemical network forming molecular ions. The relaxation of these ions results in characteristic line emission, which can be predicted. We show that the ionization rate for at least two objects is more than an order of magnitude above Galactic average for molecular clouds, hinting at an enhanced formation rate of molecular ions. There will be interesting opportunities to measure crucial molecular ions in the infrared and submillimeter-wave parts of the spectrum.

Punjabi immigrant women’s narratives of mental health and health care utilization
Creators: name: Jhangiani, Surita
Publisher: name: University of British Columbia
Year: 2011

description: Indian Punjabis constitute a large proportion of the immigrant population in the Lower Mainland of BC. By 2031, it is anticipated that South Asians will be the largest visibility minority group in Canada (Statistics Canada, 2005). As a result, the mental health needs of this population may soon have a large impact on mental health providers. The present study investigated how Punjabi immigrant women constructed the meaning of mental health through the following research questions: 1) How do Punjabi immigrant women define concepts related to mental health and illness?; 2) How are mental health services accessed and utilized by the participants?; 3) In what ways do the existing mental health services meet or fail to meet the needs of the participants?; 4) How can these services be made more culturally accessible?; and 5) How is mental health defined by prominent mental health organizations? Drawing from feminist post-colonial theory and utilizing a critical qualitative approach, the first segment of this study was a narrative analysis of qualitative interviews that enabled an understanding of the participants’ views of mental health and experiences accessing mental health services and; the second segment of the study critically analyzed documents pertaining to the meaning of mental health as defined by three prominent mental health organizations. The results of this study suggested that the participants’ conceptions of mental health shared some similarities with Western models. The meanings that the participants constructed for various concepts, and their underlying metaphors, however, differed from Western models of mental health. Further, cultural conventions and perceptions often affected how participants’ viewed mental health issues and the type of help they sought. Recommendations, limitations and challenges, and future directions are discussed. As critical research, the results of this study contribute to the ongoing development of a culturally responsive approach to health care provision.

description: Recent farm financial stress has hit the Midwest the hardest because farming there is specialized and the Midwest's overall economy has not rebounded from the 1980-82 recessions. Though the number of farmers working off the farm is growing nationally, more plentiful nonfarm jobs in the Northeast and South have helped offset farmers' financial stress. Economically diversified and densely settled areas with younger residents have fared best, while heavily farming-dependent areas have fared worst and lost population. This report contains indepth comparisons of rural America's current economic health by region and by reliance on farming.

description: Transition state theory was introduced in the 1930s to account for chemical reactions. Central to this theory is the idea of a potential energy surface (PES). It was assumed that such a surface could be constructed using eigensolutions of the Schrödinger equation for the molecular (Coulomb) Hamiltonian but at that time such calculations were not possible. Nowadays quantum mechanical ab-initio electronic structure calculations are routine and from their results PESs can be constructed which are believed to approximate those assumed derivable from the eigensolutions. It is argued here that this belief is unfounded. It is suggested that the potential energy surface construction is more appropriately regarded as a legitimate and effective modification of quantum mechanics for chemical purposes

description: The design principle of maximizing local autonomy except when it conflicts with global robustness has led to a scalable Internet with enormous heterogeneity of both applications and infrastructure. These properties have not been achieved in the mechanisms for specifying and enforcing security policies. The STRONGMAN (for Scalable TRust Of Next Generation MANagement) system [9], [10] offers three new approaches to scalability, applying the principle of local policy enforcement complying with global security policies. First is the use of a compliance checker to provide great local autonomy within the constraints of a global security policy. Second is a mechanism to compose policy rules into a coherent enforceable set, e.g., at the boundaries of two locally autonomous application domains. Third is the "lazy instantiation" of policies to reduce the amount of state that enforcement points need to maintain. In this paper, we focus on the issues of scalability and heterogeneity.

A Not-So-Fundamental Limitation on Studying Complex Systems with Statistics: Comment on Rabin (2011)

description: Although living organisms are affected by many interrelated and unidentified variables, this complexity does not automatically impose a fundamental limitation on statistical inference. Nor need one invoke such complexity as an explanation of the "Truth Wears Off" or "decline" effect; similar "decline" effects occur with far simpler systems studied in physics. Selective reporting and publication bias, and scientists' biases in favour of reporting eye-catching results (in general) or conforming to others' results (in physics) better explain this feature of the "Truth Wears Off" effect than Rabin's suggested limitation on statistical inference.

Augusteische Mythen – private Staatsreliefs?
Creators: name: Sporleder, Rolf Frank
Publisher: name: Humboldt-Universität zu Berlin
Year: 2020
Subjects: subject: 930 Geschichte des Altertums bis ca. 499, Archäologie

description: Rolf Frank Sporleder [Augusteische Mythen – private Staatsreliefs? Eine kritische Analyse mythologischer Szenen auf Kleinkunst] geht der Frage nach, inwieweit bestimmte mythologische Szenen als Allegorien auf oder Vergleich zu Augustus Biografie und der Ereignisgeschichte verstanden werden können. Dabei diskutiert Sporleder einschlägige Fallbeispiele der Kleinkunst, für die eine solche Deutung vorgeschlagen wird. Es wird dabei diskutiert, inwieweit die Selbstrepräsentation des Augustus, die aus dem öffentlichen Raum wohl bekannt ist, sich auch auf die private Sphäre erstreckte.
Measurement of the jet fragmentation function and transverse profile in proton-proton collisions at a center-of-mass energy of 7 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The jet fragmentation function and transverse profile for jets with 25 GeV < ptJet < 500 GeV and etaJet<1.2 produced in proton-proton collisions with a center-of-mass energy of 7 TeV are presented. The measurement is performed using data with an integrated luminosity of 36 pb^-1. Jets are reconstructed and their momentum measured using calorimetric information. The momenta of the charged particle constituents are measured using the tracking system. The distributions corrected for detector effects are compared with various Monte Carlo event generators and generator tunes. Several of these choices show good agreement with the measured fragmentation function. None of these choices reproduce both the transverse profile and fragmentation function over the full kinematic range of the measurement.

description: Das Poster stellt den Stand der Implementierung von FAIR-Prinzipien an der Charité – Universitätsmedizin Berlin im Jahr 2021 dar. Das Projekt wurde durch Berlin University Alliance gefördert. Die Ergebnisse wurden in das bestehende Charité Dashboard on Responsible Research integriert. Das Poster zu den Daten aus dem Jahr 2020 ist unter 10.5281/zenodo.7245695 zu finden. Für die Analyse wurden Forschungsdaten untersucht, die gemeinsam mit im Jahr 2021 erschienenen Artikeln veröffentlicht wurden, und die öffentlich in Datenrepositorien zugänglich sind. Für jedes Repositorium, das im Artikel zitiert wurde, wurde ein Identifier (URL oder DOI) an das Screening-Tool F-UJI gesendet. F-UJI berechnet anhand von Metriken und Tests einen Score, der die prozentuale Erfüllung der einzelnen FAIR-Prinzipien pro Datensatz anzeigt. Die interaktiven Charts sollen Wissen über die FAIR-Prinzipien und ihr Monitoring vermitteln und ein Bewusstsein dafür schaffen, welche Voraussetzungen "FAIRe" und somit nachhaltig nachnutzbare Daten erfüllen müssen. Das Poster präsentiert unter anderem wie hoch der Grad der Erfüllung verschiedener FAIR-Prinzipien in diesem Sample insgesamt ist, und wie sich dies je nach Repositorium unterscheidet.

A Twistor Description of Six-Dimensional N=(1,1) Super Yang-Mills Theory

description: We present a twistor space that describes super null-lines on six-dimensional N=(1,1) superspace. We then show that there is a one-to-one correspondence between holomorphic vector bundles over this twistor space and solutions to the field equations of N=(1,1) super Yang-Mills theory. Our constructions naturally reduce to those of the twistorial description of maximally supersymmetric Yang-Mills theory in four dimensions.

Laughter Detection in Meetings
Creators: name: Kennedy, Lyndon S.

Subjects: Electrical engineering

description: We build a system to automatically detect laughter events in meetings, where laughter events are defined as points in the meeting where a number of the participants (more than just one) are laughing simultaneously. We implement our system using a support vector machine classifier trained on mel-frequency cepstral coefficients (MFCCs), delta MFCCs, modulation spectrum, and spatial cues from the time delay between two desktop microphones. We run our experiments on the 'Bmr' subset of the ICSI Meeting Recorder corpus using just two table-top microphones and obtain detection results with a correct accept rate of 87% and a false alarm rate of 13%.

description: Simone Mulattieri [„Probantur quam maxime mellei coloris” (Plin. nat. 36, 12, 61). Der kulturelle Transformationsprozess von Alabastergefäßen in augusteischer Zeit] untersucht die semantischen Qualitäten eines besonderen Rohstoffes, dem Gestein Alabaster. Obwohl bereits die Etrusker eine Alabasterart in Latium abbauten, wird das Material ab augusteischer Zeit aus Ägypten importiert und für Urnen gebraucht. Mulattieri wertet nicht nur archäologische Zeugnisse, sondern auch Schriftquellen aus, um der Frage nachzugehen, wieso unter Augustus ein besonderes Interesse für dieses ausgerechnet aus Ägypten stammende Material entstand.
