description: Discoveries of natural and cultural heritage, such as fossils or Indigenous artefacts/sites, are often found not by scientists, but by ordinary citizens who are unfamiliar with heritage laws However, the perceptions of these non specialist members of the community including how th ese perceptions may affect heritage conservation, have been poorly studied. To address this problem, the Found a Fossil project was created, with the release of an Australia wide survey that aimed to understand how Australians pe rceive heritage material what they may do upon its discovery, and their awareness of current heritage protections. Results show that while there is enthusiasm to report finds, confusion over the appropriate authorities to contact, a lack of transparency by government, and poorly communicated legislation a re creating barriers to heritage protection in Australia. While survey responses helped to identify concerns and problems with current heritage protections, they also illustrated potential solutions that cater to the wants and needs of local communities. This project represents the first analysis to comprehensively cover Australian perceptions of both Indigenous artefacts and fossils, and provides recommendations for future initiatives that can contribute to the improved protection and celebration of Australian heritage, and the incredible stories it can tell.

description: If the Dark Matter consists of primordial black holes (PBHs), we show that gravitational lensing of stars being monitored by NASA's Kepler search for extra-solar planets can cause significant numbers of detectable microlensing events. A search through the roughly 150,000 lightcurves would result in large numbers of detectable events for PBHs in the mass range $5 \ten{-10}\msun$ to $\aten{-4}\msun$. Non-detection of these events would close almost two orders of magnitude of the mass window for PBH dark matter. The microlensing rate is higher than previously noticed due to a combination of the exceptional photometric precision of the Kepler mission and the increase in cross section due to the large angular sizes of the relatively nearby Kepler field stars. We also present a new formalism for calculating optical depth and microlensing rates in the presence of large finite-source effects.

description: Following birth, infants must immediately process and rapidly adapt to the array of unknown sensory experiences associated with their new ex-utero environment. However, although it is known that unimodal stimuli induce activity in the corresponding primary sensory cortices of the newborn brain, it is unclear how multimodal stimuli are processed and integrated across modalities. The latter is essential for learning and understanding environmental contingencies through encoding relationships between sensory experiences; and ultimately likely subserves development of life-long skills such as speech and language. Here, for the first time, we map the intracerebral processing which underlies auditory-sensorimotor classical conditioning in a group of 13 neonates (median gestational age at birth: 38 weeks + 4 days, range: 32 weeks + 2 days to 41 weeks + 6 days; median postmenstrual age at scan: 40 weeks + 5 days, range: 38 weeks + 3 days to 42 weeks + 1 days) with blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (MRI) and magnetic resonance (MR) compatible robotics. We demonstrate that classical conditioning can induce crossmodal changes within putative unimodal sensory cortex even in the absence of its archetypal substrate. Our results also suggest that multimodal learning is associated with network wide activity within the conditioned neural system. These findings suggest that in early life, external multimodal sensory stimulation and integration shapes activity in the developing cortex and may influence its associated functional network architecture.

description: We report evidence for a striking difference between S0 galaxies in the local field and in the Virgo Cluster. While field S0 galaxies have disks whose surface-brightness profiles are roughly equally divided between the three main types (Types I, II, and III: single-exponential, truncated, and antitruncated), Virgo S0s appear to be entirely lacking in disk truncations. More specifically, the fraction of truncations in S0 galaxies with M_B < -17 is 28% +7/-6% for the field, versus 0% +4/-0% for the Virgo Cluster galaxies; the difference is significant at the 99.7% level. The discrepancy is made up almost entirely by Type I profiles, which are almost twice as frequent in the Virgo Cluster as they are in the field. This suggests that S0 formation may be driven by different processes in cluster and field environments, and that outer-disk effects can be useful tests of S0 formation models.

description: Die vorliegende Arbeit mit dem Titel Rudolf von Eichthal − Soldat, Musiker und Schriftsteller. Sein Leben und Schaffen im Spiegel seiner Tagebücher und literarischen Werke versucht eine Rekonstruktion des Werdegangs des vielseitigen und von den 1930er bis in die 1960er Jahre vielgelesenen Autors. Anhand seiner umfangreichen Verlassenschaft, die sich in der Hand-schriftensammlung der Österreichischen Nationalbibliothek befindet und 60 Tagebücher, 43 Notizbücher, Dokumente, Briefe etc. umfasst, und seiner zahlreichen Romane, Novellen- und Geschichtenbände werden die Stationen von Eichthals Leben nachgezeichnet. Dabei wird auf seine Karriere als Offizier bis nach dem 1. Weltkrieg sowie auf seine unterschiedlichen künst-lerischen Begabungen als Trompeter, Dirigent und Verfasser von literarischen Werken, die hauptsächlich in der Zeit der Habsburgermonarchie angesiedelt sind, eingegangen. Als un-politischer Schriftsteller konnte er in der Zwischenkriegszeit, während des 2. Weltkrieges und danach seine meist im Militärbereich spielenden Romane, Novellen und Geschichten publizieren. Zwei zentrale Forschungsfragen ergaben sich bei der Abfassung dieser Arbeit: Inwieweit ermöglichen Eichthals faktuale Texte (Tagebücher, Dokumente, Briefe) die Erstellung einer Biographie? Welche biographischen Erfahrungen transformiert der Autor in seine fiktionalen Texte? Dazu erfolgte zuerst eine Abgrenzung der Textquellen nach Faktualität und Fiktionalität, um eine entsprechende Zuordnung der vorhandenen schriftlichen Unterlagen vornehmen zu können. Danach wurden Tage-, Notizbücher und andere Dokumente sowie als faktual erachtete Jugenderinnerungen zur Erstellung einer Biographie Eichthals herangezogen. Der dritte Teil der Arbeit befasst sich mit einer Gegenüberstellung von biographischen Erfahrungen und deren Transformation in Romane, Novellen und Geschichten, wobei hauptsächlich auf die Romantetralogie über Erwin Spielvogel, bestehend aus Der göttliche Funke (1937), Die goldene Spange (1942), Der grüne Federbusch (1951) und Der Marschallstab (1952), sowie auf die Novelle „Casa nera“ aus Miczike (1931) und die Geschichten „Die schöne Leontine“ aus dem Soldatengeschichtenband Gott erhalte! (1966) und „Die hohe Frau“ aus dem Geschichtenband Der Steinadler (1954) zurückgegriffen wird. Zuletzt wird den Fragen nachgegangen, ob Eichthal als Vertreter des habsburgischen Mythos im Sinne von Claudio Magris zu betrachten sei und warum er heute fast völlig vergessen ist.
The classroom and the polis : political action, dialogue and the project of pedagogy

description: This study explores students’ experiences in a dialogue-based program and what these experiences reveal about the possibility of creating dialogic classroom spaces that engage the political and support the emergence of students as political actors. The case study was a semester-long, undergraduate program in a comprehensive university in western Canada. The theme for dialogue was “Indigeneity in Canada: Past, Present, and Future.” In a qualitative case study, I observed classroom interactions, wrote field notes and interviewed students and instructors over the course of thirteen weeks. Working hermeneutically, I interpreted the data by placing it in conversation with the political theory of Hannah Arendt. The students’ experiences revealed the dialogue-based classroom as a pseudo-public space repeatedly under threat from the larger social pressures of conformity, utilitarian thinking and emotional self-interest. The students’ experiences in the program tell a story marked by profound struggles for political voice, authentic relations, and a sense of equality. Confounding students struggle to appear in the dialogue was the potentially volatile psychological dimension of learning. The inherent unpredictability of the classroom as a public space cast the teacher, not as ring-leader or director, but as one who attempted to hold open the spaces so that the students could continually return, willing to take the risk that speech and action are in the public realm.

description: Generalised Teleparallel gravity, also referred to as f(T) gravity, has been recently proposed as an extended theory of gravitation able to give rise to an accelerated expansion in a matter only universe. The cosmic speed up is driven by an effective torsion fluid whose equation of state depend on the f(T) function entering the modified gravity Lagrangian. We focus on two particular choices for f(T) which share the nice property to emulate a phantom divide crossing as suggested by some recent data. We check their viability contrasting the predicted background dynamics to the Hubble diagram as traced by both Type Ia Supernovae (SNeIa) and Gamma Ray Bursts (GRBs), the measurement of the rate expansion H(z), the Baryon Acoustic Oscillations (BAOs) at different redshifts, and the Cosmic Microwave Background Radiation (CMBR) distance priors. Both f(T) models turn out to be in very good agreement with this large dataset so that we also investigate whether it is possible to discriminate among them relying on the different growth factors.

description: We investigate decoherence in quantum systems coupled via dephasing-type interactions to an arbitrary environment with chaotic underlying classical dynamics. The coherences of the reduced state of the central system written in the preferential energy eigenbasis are quantum Loschmidt echoes, which in the strong coupling regime are characterized at long times scales by fluctuations around a constant mean value. We show that due to the chaotic dynamics of the environment, the mean value and the width of the Loschmidt echo fluctuations are inversely proportional to the quantity we define as the effective Hilbert space dimension of the environment, which in general is smaller than the dimension of the entire available Hilbert space. Nevertheless, in the semiclassical regime this effective Hilbert space dimension is in general large, in which case even a chaotic environment with few degrees of freedom produces decoherence without revivals. Moreover we show that in this regime the environment leads the central system to equilibrate to the time average of its reduced density matrix, which corresponds to a diagonal state in the preferential energy eigenbasis. For the case of two uncoupled, initially entangled central systems that interact with identical local quantum environments with chaotic underlying classical dynamics, we show that in the semiclassical limit the equilibration state is arbitrarily close to a separable state. We confirm our results with numerical simulations in which the environment is modeled by the quantum kicked rotor in the chaotic regime.

The significance of the imaginary part of the weak value

description: Unlike the real part of the generalized weak value of an observable, which can in a restricted sense be operationally interpreted as an idealized conditioned average of that observable in the limit of zero measurement disturbance, the imaginary part of the generalized weak value does not provide information pertaining to the observable being measured. What it does provide is direct information about how the initial state would be unitarily disturbed by the observable operator. Specifically, we provide an operational interpretation for the imaginary part of the generalized weak value as the logarithmic directional derivative of the post-selection probability along the unitary flow generated by the action of the observable operator. To obtain this interpretation, we revisit the standard von Neumann measurement protocol for obtaining the real and imaginary parts of the weak value and solve it exactly for arbitrary initial states and post-selections using the quantum operations formalism, which allows us to understand in detail how each part of the generalized weak value arises in the linear response regime. We also provide exact treatments of qubit measurements and Gaussian detectors as illustrative special cases, and show that the measurement disturbance from a Gaussian detector is purely decohering in the Lindblad sense, which allows the shifts for a Gaussian detector to be completely understood for any coupling strength in terms of a single complex weak value that involves the decohered initial state.

description: Andrew Linzey bietet einen theologischen Entwurf einer pathozentrischen Tierethik, der die zentrale Anfrage an die säkularen pathozentrischen Entwürfe seiner Zeitgenossen Peter Singer und Tom Regan aufnimmt und überwindet. In seiner Konzeption wird der Eigenwert von Tieren nicht auf Kosten der vulnerabelsten Menschen begründet, insofern nicht primär der Nachweis bestimmter Fähigkeiten, sondern das Geliebt-Sein durch Gott entscheidend ist. Nach einer Einführung in Linzeys Person und seinem Anliegen und einer Erläuterung seiner zentralen Begriffe, im ersten Teil dieser Arbeit, wird ein kurzer Überblick über die drei einflussreichsten tierethischen Strömungen geboten. Es werden der radikale und gemäßigte Anthropozentrismus, der Biozentrismus und der Pathozentrismus vorgestellt, um Linzey besser einordnen zu können. Der Hauptteil der Arbeit beschäftigt sich mit seiner Begründung eines Eigenwerts von Tieren. Hierzu ist für ihn die trinitarische Liebe leitend, die in weiterer Folge die Darstellung prägen wird. Schöpfungstheologisch wird ein Eigenwert der Schöpfung im Allgemeinen und jedes Geschöpfes im Einzelnen aufgrund des Geliebt-Seins durch Gott in ihrem bloßen Geschöpf-Sein begründet. Pneumatologisch wird darüber hinaus der besondere, inhärente Wert aller geisterfüllten und damit auf Gottes Ruf antwort- und bundesfähigen Lebewesen begründet. Dies wird in einer ersten handlungsnormativen Konkretion mittels Theos-Rechten zu Linzeys Konzept von Tierrechten verarbeitet. Hierbei vertritt er eine exklusive Sicht, die solche moralischen Rechte auf Säugetiere und Vögel beschränkt, da bei ihnen unzweifelhaft eine zum Menschen analoge Empfindungsfähigkeit und damit auch spirituelle Fähigkeiten angenommen werden können. In einer zweiten handlungsnormativen Konkretion verdeutlicht Linzey christologisch die Bedeutung der Gottebenbildlichkeit der Menschheit als dienende Spezies und den aus dem Leben Jesu heraus aufleuchtenden großmütigen Charakter des Herrschaftsauftrags an den Menschen. Wie Eltern ihren Kindern großmütig begegnen, soll in einer Ethik der Großmütigkeit der Mensch die Tiere aufgrund ihrer Andersheit nicht weniger, sondern mehr berücksichtigen. Nach einer kritischen Würdigung des Linzey’schen Ansatzes wird anhand der Frage nach einem christlich motivierten Vegetarismus ein Anwendungsfeld näher beleuchtet.

description: [Abridged] Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that have all the properties of type 1 Seyfert galaxies but show peculiar characteristics, including the narrowest Balmer lines, strongest Fe II emission, and extreme properties in the X-rays. Line and continuum radio observations provide an optimal tool to access the (often) optically obscured innermost regions of AGN and reveal the kinematics of the gas around their central engines. We investigate the interplay between the peculiar NLS1 class of AGN and the maser phenomenon, to help us understand the nature of the maser emission in some NLS1s where water maser emission has been detected. We observed a sample of NLS1 galaxies with the Green Bank Telescope in a search for water maser emission at 22 GHz. We also reduced and analysed archival Green Bank Telescope and Very Large Array data and produced 22-GHz spectra for the five NLS1 galaxies with detected maser emission. In particular, we imaged the maser and nuclear radio continuum of NGC5506 at subarcsec scales with the Very Large Array. We discovered maser emission in two NLS1 galaxies: IGRJ16385-2057, and IRAS03450+0055. In addition to the three previously known maser detections in the NLS1s Mrk766, NGC4051, and NGC5506, this yields a water maser detection rate in NLS1 galaxies of ~7% (5/71). This value rises significantly to ~21% (5/24) when considering only NLS1 galaxies at recessional velocities less than 10000 km/s. For NGC4051 and NGC5506, we find that the water maser emission is located within 5 and 12 pc, respectively, of nuclear radio continuum knots, which are interpreted as core-jet structures.

description: Stochastic computing (SC) is an unconventional computing style that uses probabilistic bitstreams to implement algorithms like those for machine learning, digital filtering, and image processing. SC's unusual encoding enables highly fault tolerant, low power, and small datapaths. For instance, a single AND gate performs multiplication in SC. SC's advantages make it attractive for use in small devices like wearables and biomedical implants, but widespread adoption of SC has been limited due to challenges including a steep accuracy-latency trade-off and expensive interface circuits. We address these challenges using a statistical approach. First, we develop a better framework for analyzing stochastic circuit errors and then use insights from statistical analysis to design and evaluate smaller and more accurate circuits. Understanding SC's many error sources is key to developing more accurate designs. However, existing approaches to accuracy analysis fail to provide a comprehensive account of all error types. The first part of this thesis proposes a novel framework named Bayesian Analysis of Stochastic Errors (BASE). BASE is built on statistical estimation theory and identifies three key quantities that must be modeled or estimated to quantify a circuit's accuracy. BASE is used to better understand and address circuit errors and is compatible with prior methods for error analysis as well as new models that we propose in this thesis. Importantly, BASE reduces the reliance on black box simulation methods which provide limited insight and are prone to mistakes. SC's low-cost multipliers make it attractive for neural network and digital filtering applications. However, accurate addition is difficult to implement in SC and overhead from SC's data conversion circuits reduces SC's advantage for these applications. We address these problems by using insights from statistical modeling to develop new and better SC designs. Three such designs are introduced: 1) CeMux, a multiplexer adder that is significantly more accurate and smaller than its predecessors, 2) parallel sampling adders which have a flexible area-accuracy trade-off that can be tuned for the application, and 3) multiplexer-majority chains which can reduce the overhead of SC's conversion units. We apply our new designs to tasks like electrocardiogram filtering, image edge detection, and image classification with binarized neural networks as well as higher-precision neural networks.

description: Aims. In the first few minutes of a newborn neutron star's life the Hall effect and differential rotation may both be important. We demonstrate that these two ingredients are sufficient for generating a 'shear-Hall instability' and for studying its excitation conditions, growth rates, and characteristic magnetic field patterns. Methods. We numerically solve the induction equation in a spherical shell, with a kinematically prescribed differential rotation profile Ω(s), where s is the cylindrical radius. The Hall term is linearized about an imposed uniform axial field. The linear stability of individual azimuthal modes, both axisymmetric and non-axisymmetric, is then investigated. Results. For the shear-Hall instability to occur, the axial field must be parallel to the rotation axis if Ω(s) decreases outward, whereas if Ω(s) increases outward it must be anti-parallel. The instability draws its energy from the differential rotation, and occurs on the short rotational timescale rather than on the much longer Hall timescale. It operates most efficiently if the Hall time is comparable to the diffusion time. Depending on the precise field strengths B0, either axisymmetric or non-axisymmetric modes may be the most unstable. Conclusions. Even if the differential rotation in newborn neutron stars is quenched within minutes, the shear-Hall instability may nevertheless amplify any seed magnetic fields by many orders of magnitude.

description: Metabolic rewiring is a hallmark of pancreatic ductal adenocarcinomas (PDA), a lethal disease that is notoriously resistant to therapies. This is due in part to the tumor microenvironment, which is largely composed of a dense fibrotic stroma and extracellular matrix. Hyaluronic acid (HA), a linear, carbohydrate polymer and a key component of the extracellular matrix, is a major contributor to the elevated interstitial pressure, resulting in vascular collapse that impedes drug delivery and creates an aberrant nutrient landscape. To survive and proliferate in this environment, pancreatic cancer cells rewire their metabolism and scavenge from the tumor microenvironment. Nearly all pancreatic tumors harbor mutations in oncogenic Kras, which increases the glycolytic flux into the hexosamine biosynthetic pathway (HBP). As such, the HBP potentially represents a metabolic vulnerability that could reveal novel targets for disease treatment. The underlying goal of this thesis is to define the role of HBP in pancreatic cancer. This dissertation provides a comprehensive review on pancreatic cancer metabolism, tumor microenvironment, and the role of HBP in other cancers (Chapter 1). Testing for PDA dependence on the HBP revealed HA as a novel nutrient source that fuels the HBP via the N-acetyl-glucosamine salvage pathway (Chapter 2). Furthermore, future work stemming from preliminary findings will investigate whether inhibition of cell-intrinsic HBP is sufficient to sensitize pancreatic cancer to anti-PD-(L)1 therapy, an immune checkpoint blockade immunotherapy that has not been successful in PDA, despite demonstrating revolutionary success in other cancers (Chapter 3). Finally, this dissertation proposes several future directions: the elucidation of the GlcNAc salvage pathway in more physiologically relevant models, further mechanistic delineation of HA fueling the HBP, and testing whether other non-cancerous cells populating the tumor microenvironment and components of the extracellular matrix can regulate the HBP in cancer cells (Chapter 4).

description: RDBMS is the heart for both OLTP and OLAP types of applications. For both types of applications thousands of queries expressed in terms of SQL are executed on daily basis. All the commercial DBMS engines capture various attributes in system tables about these executed queries. These queries need to conform to best practices and need to be tuned to ensure optimal performance. While we use checklists, often tools to enforce the same, a black box technique on the queries for profiling, outlier detection is not employed for a summary level understanding. This is the motivation of the paper, as this not only points out to inefficiencies built in the system, but also has the potential to point evolving best practices and inappropriate usage. Certainly this can reduce latency in information flow and optimal utilization of hardware and software capacity. In this paper we start with formulating the problem. We explore four outlier detection techniques. We apply these techniques over rich corpora of production queries and analyze the results. We also explore benefit of an ensemble approach. We conclude with future courses of action. The same philosophy we have used for optimization of extraction, transform, load (ETL) jobs in one of our previous work. We give a brief introduction of the same in section four.

With this increasing demand for individuals with STEM degrees in Canada, it is more important than ever for universities to focus on enhancing students’ academic experiences (AUCC, 2007). Administrators within the Faculty of Science at the University of British Columbia (UBC) were concerned with improving the success of their students and were eager to understand what factors students perceived as influential to their academic performance. This concern fostered the orchestration of this mixed method study with data being collected via a survey (roughly 500 respondents), 24 one-on-one interviews and a four-person focus group discussion. The quantitative and qualitative data were analyzed to determine the factors that students perceived as most important to influencing their performance in science and why these factors were perceived as important. The data was also analyzed for gender differences. Students identified several academic, social and personal factors as influential but the most important factors were related to: the role of the instructor, assessment methods, study skills and habits, community, and the involvement of others. In comparison to males, females placed more emphasis on the approachability of their instructors, assessment methods, study skills and habits, the involvement of others and commuting. Based on the results of this study, recommendations were provided for administrators, faculty, and students on how they could positively affect the academic performance of undergraduates in science programs at UBC.

description: Tabled evaluation is a recognized and powerful technique that overcomes some limitations of traditional Prolog systems in dealing with recursion and redundant sub-computations. We can distinguish two main categories of tabling mechanisms: suspension-based tabling and linear tabling. While suspension-based mechanisms are considered to obtain better results in general, they have more memory space requirements and are more complex and harder to implement than linear tabling mechanisms. Arguably, the SLDT and DRA strategies are the two most successful extensions to standard linear tabled evaluation. In this work, we propose a new strategy, named DRS, and we present a framework, on top of the Yap system, that supports the combination of all these three strategies. Our implementation shares the underlying execution environment and most of the data structures used to implement tabling in Yap. We thus argue that all these common features allows us to make a first and fair comparison between these different linear tabling strategies and, therefore, better understand the advantages and weaknesses of each, when used solely or combined with the others.

description: We show that orbital currents in a CuO2 plane, if present, should be described by two independent parity and time-reversal odd order parameters, a toroidal dipole (anapole) and a magnetic quadrupole. Based on this, we derive the resonant X-ray diffraction cross-section for monoclinic CuO at the antiferromagnetic wavevector and show that the two order parameters can be disentangled. From our analysis, we examine a recent claim of detecting anapoles in CuO.

description: Dem Prosa-Werk der Kärntner Schriftstellerin Christine Lavant kam lange nicht die Aufmerksamkeit zuteil, die es verdiente. Die vorliegende Masterarbeit beleuchtet Lavants Erzählung "Aufzeichnungen aus dem Irrenhaus", geschrieben 1946 und erstmals veröffentlicht 2001, aus einer intersektionalen, gesellschaftskritischen und emanzipatorischen Perspektive. Es wird der Frage nachgegangen, wie in "Aufzeichnungen aus dem Irrenhaus" Vorstellungen eines ‚erkrankten‘ und ‚gesunden‘ Körpers de_konstruiert werden. Mittels einer genderorientieren und intersektionalen Erzähltextanalyse sowie eines grundsätzlich dekonstruktiven und diskurskritischen Ansatzes wird sich der Hervorbringung und Darstellung von vergeschlechtlichten, erkrankten und schichtenspezifisch ausdifferenzierten Körpern in Lavants Werk gewidmet. Die Differenzkategorien ‚Krankheit‘, ‚Geschlecht‘ und ‚Klasse‘ sowie die damit verbundenen Dominanz- und Herrschaftsverhältnisse stehen folglich im Zentrum der Analyse. Der literaturwissenschaftliche Zugang ist dabei ein grundsätzlich kulturwissenschaftlicher: Literatur beschreibt nicht nur Wirklichkeit, sondern erschreibt sie. In diesem Sinne wird ein besonderes Augenmerk auf das performative Potential literarische Texte gelegt und welche Rolle diesem in der Re_präsentation von Körper(lichkeit) zuteilwird. Als theoretisches Werkzeug dienen Judith Butlers Arbeiten zu Performativität, Vulnerabilität und Gender(-Normen), Pierre Bourdieus Habitus-Theorie und Michel Foucaults Ausführungen zum medizinischen Diskurs und Fragen nach Wissen/Macht.

description: In this paper, a poissoin-exponential distribution(PED) is considered as a lifetime model. Its statistical characteristics and important distributional properties are discussed by Louzada-Neto et al.[13]. The method of Maximum likelihood estimation and least square estimation of parameters involved along with reliability and failure rate functions is also studied here. In view of cost and time constraints, Progressive type-II censored data with binomial removals (PT-II CBRs) have been used. Finally, a real data example is given to show the practical applications of the paper.

description: Resonant production of a light, narrow techni-rho, followed by the decay $ρ_T \rightarrow W+π_T(jj)$ has been proposed as an explanation of the Wjj excess observed by CDF. If the $π_T$ decays to $τ+ν/τ^+ τ^-$ rather than to jets, subsequent leptonic $τ$ decay leads to $\ell^+\ell^- νν\barν\barν$, a final state that will be picked up by standard model $WW^{(*)} \rightarrow \ell^+\ell^-$ + MET Higgs searches. We point out that, for the same range of technicolor parameters required to fit the CDF Wjj excess, the correlated $\ell^+\ell^-$ + MET technicolor signal can have strength comparable to that of an intermediate-mass standard model Higgs boson, and therefore could be visible at the Tevatron or LHC.

description: Anovulation is a common presentation of infertility, yet in many cases the root cause is unknown. This is, in part, due to an incomplete understanding of how ovarian estradiol normally acts in the brain to initiate the cascade of physiological events leading up to ovulation. In spontaneously-ovulating mammals, this cascade is known as estradiol positive feedback, and involves ovarian estradiol facilitating a surge of gonadotropin-releasing hormone (GnRH) release from the hypothalamus. The neurophysiological basis for GnRH surge generation is not well-defined. Initiation of the GnRH surge is thought to involve neurons in the rostral hypothalamus that express the neuropeptide kisspeptin, a strong activator of GnRH release. In mice, these estradiol-sensitive neurons are in the anteroventral-periventricular area (AVPV). This dissertation involved study of the intrinsic electrical properties of AVPV kisspeptin neurons and their neural circuit interactions with GnRH neurons. Voltage-gated potassium currents of AVPV kisspeptin neurons were biophysically characterized and found to have different amplitude and voltage sensitivity in neurons from diestrous vs proestrous mice. Simulations of spiking activity suggested concomitant increases in T-type calcium, persistent sodium, and hyperpolarization activated currents during proestrus promote burst-firing activity. This is likely to contribute to increased kisspeptin release by these cells during the GnRH surge. Signaling between AVPV kisspeptin and GnRH neurons was studied in diestrous, proestrous, ovariectomized, and ovariectomized-estradiol-treated mice. It was found that GnRH neurons exhibit immediate and delayed increases in spike rate upon photoactivation of AVPV kisspeptin neurons. Immediate increases in spike rate were due to evoked monosynaptic excitatory GABAergic PSCs, and were absent in ovariectomized mice. Delayed increases in firing did not require a monosynaptic connection, suggesting peptidergic transmission can occur in absence of co-transmitted activators of ionotropic receptors. The evoked increase in GnRH neuron firing rate was not different between diestrous and proestrous mice, suggesting increased activation of this circuit during positive feedback is not primarily driven by modulation of synaptic strength or an increase in the efficacy of metabotropic transmission. This places increased emphasis on AVPV kisspeptin neuron spiking activity as a primary determinant of GnRH surge initiation.

description: This paper proposes a novel latent semantic learning method for extracting high-level features (i.e. latent semantics) from a large vocabulary of abundant mid-level features (i.e. visual keywords) with structured sparse representation, which can help to bridge the semantic gap in the challenging task of human action recognition. To discover the manifold structure of midlevel features, we develop a spectral embedding approach to latent semantic learning based on L1-graph, without the need to tune any parameter for graph construction as a key step of manifold learning. More importantly, we construct the L1-graph with structured sparse representation, which can be obtained by structured sparse coding with its structured sparsity ensured by novel L1-norm hypergraph regularization over mid-level features. In the new embedding space, we learn latent semantics automatically from abundant mid-level features through spectral clustering. The learnt latent semantics can be readily used for human action recognition with SVM by defining a histogram intersection kernel. Different from the traditional latent semantic analysis based on topic models, our latent semantic learning method can explore the manifold structure of mid-level features in both L1-graph construction and spectral embedding, which results in compact but discriminative high-level features. The experimental results on the commonly used KTH action dataset and unconstrained YouTube action dataset show the superior performance of our method.
