On the gravitational angular momentum of rotating sources

description: The gravitational energy-momentum and angular momentum satisfy the algebra of the Poincare group in the full phase space of the teleparallel equivalent of general relativity. The expression for the gravitational energy-momentum may be written as a surface integral in the three-dimensional spacelike hypersurface, whereas the definition for the angular momentum is given by a volume integral. It turns out that in practical calculations of the angular momentum of the gravitational field generated by localized sources like rotating neutron stars, the volume integral reduces to a surface integral, and the calculations can be easily carried out. Similar to previous investigations in the literature, we show that the total angular momentum is finite provided a certain asymptotic behaviour is verified. We discuss the dependence of the gravitational angular momentum on the frame, and argue that it is a measure of the dragging of inertial frames.

description: We could say that Burroughs is the death's head spoiling the group portrait of American literature, and Naked Lunch is a blot on the literary landscape, a stain on the canon of not only mainstream realist fiction but of postmodern fiction, too. Naked Lunch just doesn't fit, is neither properly in nor out of the picture, neither comfortably inside the canon nor comfortably absent from it.

description: Four cohorts of the scyphozoan jellyfish Pelagia noctiluca were grown in the laboratory and compared to in situ growth observations in the Ligurian Sea from 1969 and 2013. For the first time P. noctiluca was grown from eggs through to reproductive adults. The maximum lifespan in laboratory was 17 months. P. noctiluca were observed to release gametes at a minimum size of 3 cm bell diameter. Laboratory growth under regular feeding conditions showed initial growth followed by stagnation until dietary conditions were altered. Maximal growth rates were up to 20% d-1 for early stages and 2-5% d-1 for adults. Maximal growth rates were comparable between field and laboratory observations.

description: Aurelia aurita ecology is well known. However, critical periods of its life cycle have been overlooked, such as polyps, which are crucial in shaping blooms intensity. Thau lagoon, a coastal lagoon in Northwestern Mediterranean, offers an ideal framework to investigate the life cycle of the species. Here we study the benthic and pelagic dynamics of A. aurita in Thau lagoon over a 4-year period, focusing on the sources of population growth and mortality. Field surveys were conducted to assess benthic population distribution, settlement surfaces, density and budding. Pelagic abundances and growth were also monitored. Mortality was assessed by complementary methods consisting in molecular analysis of fish gut contents and predation experiments using Sparus aurata. The results of this study show that the dynamics of the species is mainly shaped by temperature, while the benthic phase further benefits from habitat modification. In situ, Sarpa salpa was confirmed as a predator of A. aurita, while in laboratory S. aurata consumed all development stages. However, selectivity experiments demonstrated that high quality preys were preferred. Overall, these results shed light on driving factors shaping jellyfish blooms and contribute to the mounting acknowledgment that jellyfish are not dead end in food webs.
The assessment of ten passive solar buildings in Tasmania

Year: 2023

description: As many future home owners and professionals in the building industry are looking for existing solar buildings to find out information on features such as their appearance, price ranges, and the effectiveness of solar heating design, this thesis intends to provide that information and will assess a variety of passive solar buildings in Tasmania. This thesis will catalogue ten Tasmanian passive solar buildings and particularly highlight the following factors: a) the theoretical concepts of using passive solar designs; b) the appearance and architectural layout of the passive solar buildings; c) how, and how effectively, the passive solar system works; d) the problems (if any) related to the actual construction and maintenance of the solar systems; and e) the owner's own personal experience living and using such a solar building. The thesis is presented in two major parts. The first part, consisting of Chapter Two and Three, introduces some theoretical aspects of passive solar design and briefly reviews several other surveys of solar buildings. Chapter Two looks at aspects of thermal comfort and shows why space heating is such an important factor in Tasmania. This is then related to the various key components of passive solar design as they apply in the State. Chapter Three demonstrates that the technique of cataloguing existing solar buildings is a valid and useful means of advancing the state of the art in solar design, but that regional differences in climate, building practice, and lifestyle mean that these catalogues should be prepared for a particular region to be most effective. The second part of this thesis catalogues and evaluates ten passive solar buildings, all situated in Tasmania. Documentation of each of these buildings is presented in two parts, first, the technical aspects of the building are explained and, secondly, an owner analysis of the building's performance is given.
Cross-entropy optimiser: a new tool to study precession in astrophysical jets

description: Evidence of jet precession in many galactic and extragalactic sources has been reported in the literature. Much of this evidence is based on studies of the kinematics of the jet knots, which depends on the correct identification of the components to determine their respective proper motions and position angles on the plane of the sky. Identification problems related to fitting procedures, as well as observations poorly sampled in time, may influence the follow up of the components in time, which consequently might contribute to a misinterpretation of the data. In order to deal with these limitations, we introduce a very powerful statistical tool to analyse jet precession: the cross-entropy method for continuous multi-extremal optimisation. Only based on the raw data of the jet components (right ascension and declination offsets from the core), the cross-entropy method searches for the precession model parameters that better represent the data. In this work we present a large number of tests to validate this technique, using synthetic precessing jets built from a given set of precession parameters. Aiming to recover these parameters, we applied the cross-entropy method to our precession model, varying exhaustively the quantities associated to the method. Our results have shown that even in the most challenging tests, the cross-entropy method was able to find the correct parameters within 1%-level. Even for a non-precessing jet, our optimization method could point out successfully the lack of precession.

description: We have studied the diet and the feeding behaviour of Carybdea marsupialis using different approaches. Gut contents analyses revealed copepods, mysids, and gammarids, as the main prey items, followed by polychaete, and larvae and juveniles of fish. Diet composition and proportion of empty/non empty stomachs, and prey selectivity index varied between day and night. We also present, and discuss, data on carbon and nitrogen stable isotope analysis to provide more information about the trophic role of this species. Finally, we estimated the potential predation impacts on zooplankton and fish larvae of this blooming organism by combining the results of our experiments with quantitative data on the abundance of C. marsupialis and their prey.

description: We report here the first study of proper motions of fast filaments in the young, oxygen-rich supernova remnant G292.0+1.8, carried out using a series of [O III] 5007 A emission-line images taken over a period of more than 21 years. Images taken at seven epochs from 1986 to 2008, all from telescopes at the Cerro Tololo Inter-American Observatory, show oxygen-emitting filaments, presumably ejecta fragments, throughout most of the remnant. We have measured the proper motions for 67 discrete filaments through two-dimensional correlations between images from different epochs. While the motions are small, mostly 20 to 100 milli-arcsec, they are nevertheless measurable through a robust technique of averaging measurements from many epoch pairs. The data are qualitatively consistent with a free-expansion model, and clearly show systematic motions outward from a point near the center of the radio/X-ray shell. Global fits using this model indicate an expansion center at R.A.(2000.0) = 11:24:34.4, Dec.(2000.0) = -59:15:51, and a kinematic age of 2990+-60 years. The young pulsar PSR J1124-5916 is located 46 arcsec southeast of the expansion center. Assuming that it was launched by the supernova, we expect the pulsar to be moving southeastward at 16 milli-arcsec, or a transverse velocity of 440 km/s. We find the fastest ejecta along an axis oriented roughly N-S in the plane of the sky, suggesting that a bipolar explosion produced G292.0+1.8, as appears to have been the case for Cas A.

description: This poster session provides an example of how Google Calendar can be utilized to facilitate the timely and productive assessment of subscription e-resources. At Columbia University Libraries, we have constructed a program that feeds acquisitions data from our library management system into our shared Google Calendar. For each fund code, a calendar is generated, listing each payment as an event and following that event by reminders that occur at predetermined intervals prior to the next renewal date. By streaming renewal information into a familiar and user-friendly system, we are aiming to promote widespread librarian involvement in the process of timely e-resource assessment. The coding used to feed acquisitions data into Google Calendar was worked out by Nada O'Neal and is available at: https://github.com/nadaoneal/gapps_python_whatever.

We are able to change the relative phases of the wave functions in the interfering paths and induce phase jumps of pi in the Aharonov-Bohm oscillations by changing the voltage applied to the side gate or the back gate. The observed data can be well interpreted within existing models for 'dirty metals' giving a phase coherence length of the order of 1 micrometer at a temperature of 500mK.
Fast search for Dirichlet process mixture models

Publisher: name: arXiv
Year: 2009
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: Dirichlet process (DP) mixture models provide a flexible Bayesian framework for density estimation. Unfortunately, their flexibility comes at a cost: inference in DP mixture models is computationally expensive, even when conjugate distributions are used. In the common case when one seeks only a maximum a posteriori assignment of data points to clusters, we show that search algorithms provide a practical alternative to expensive MCMC and variational techniques. When a true posterior sample is desired, the solution found by search can serve as a good initializer for MCMC. Experimental results show that using these techniques is it possible to apply DP mixture models to very large data sets.
Mismatch negativity to stimulus omission?
Creators: name: Gourley, MV
Publisher: name: University Of Tasmania
Year: 2023

description: The present experiment explored the effects of stimulus omission on mismatch negativity elicitation under varying conditions of attention. Fifty subjects were divided into five groups based on attentional focus during stimulus presentation. The three experimental groups (all of whom received 10% omitted stimuli) included a Reading (ignore all stimuli) Group, a Counting (attend to omitted stimulus) Group, and a Passive Attend (attend to stimuli alone) Group. The two Control Groups (all of whom received 100% standard stimuli) comprised a Reading (ignore all stimuli) Group and a Passive Attend (attend to all stimuli alone) Group. Stimuli were presented to the subjects in a single channel binaural auditory oddball paradigm. Subjects responses to the rare tones and also to the tone prior to the rare (pre) and following the rare (post) were monitored using EEG electrodes at three vertex sites (Fz, Cz, and Pz). Results indicated, (in contrast to orienting responses to omission), that there was little evidence of any mismatch negativity to omitted stimuli in any of the attentional conditions employed within the experiment. The results did not provide any support for N‚àö¬ß‚àö¬ßt‚àö¬ßnen's (1990) suggestion that MMN may be an integral component of, or at least associated with, the OR since both appear to be preattentive neuronal mismatch mechanisms. The results did however suggest that refractory effects occurred in Post responses to the standard stimulus immediately following an omission. In addition, there was some evidence of dishabituation in the Post responses of the Reading (Ignore) Group. Only the Counting Group exhibited a significant P300 in response to the omitted stimuli predominantly at the Cz and Pz sites. The relationship between attention and mismatch negativity and its unique response to omission are considered in light of the current findings.
Examining Student Thinking Through Video Analysis
Creators: name: Preston, Michael D.
Publisher: name: Columbia University
Year: 2010
Subjects: Educational technology

description: For preservice teachers, videos of children interacting with other children or with teachers can serve as more than a repository of "virtual kids." An inquiry-based approach to watching such video, supported by tools that allow for frequent and close viewing, provides an opportunity for prospective teachers to develop their skills of observation and interpretation before entering the classroom. Furthermore, the in-depth study of videos— particularly if the videos capture situations that reveal something about children's thinking—creates a context in which teachers can act as researchers by gathering evidence, developing hypotheses, and coordinating this information as a guide for further inquiry and teaching. Over time, close and repeated viewing and analysis of video helps shift focus away from the teacher and to the child, and allows for a richer conception of the relationship between children's performance and understanding, to help better inform teaching. Research suggests that a "cognitively rich environment" can aid in the development of the skills of observation, interpretation and argument (Kuhn, 2001a; Kuhn, Shaw, & Felton, 1997). To support teachers' learning about children's thinking, and to help teachers develop these skills, the Columbia Center for New Media Teaching and Learning (CCNMTL) and Prof. Herbert Ginsburg of Teachers College, Columbia University, created a web-based video analysis system called VITAL, or "Video Interactions for Teaching and Learning." The VITAL software is a course management system with tools for enabling students to view, analyze, and write about video. The work preservice teachers perform in VITAL has a number of potential implications for teacher development: first, it grounds learning in the empirical, and second, it offers the opportunity to practice skills of observation, interpretation, and reasoning in preparation for entering the classroom. The immediate goal of the VITAL method is to help preservice teachers (or students from any discipline) become more likely to gather their own evidence of understanding and to encourage them, through repeated viewing and manual interaction with the video content, to be deliberate in validating what they see and in explaining the connections between their evidence and claims about learning. A long-range goal of the method is to help teachers develop a more conditional notion of "the truth" that encourages them to entertain alternative hypotheses and promotes further inquiry and new ideas for teaching. This process represents a recursive, iterative response to new events; gathering more information creates the need for new evidence. By practicing these activities in a controlled setting, teachers can then prepare for classroom-based formative assessment.
Comparative reproductive biology of the Tasmanian freshwater crayfishes Astacopsis gouldi Clark, Astacopsis franklinii, Gray and Parastacoides tasmanicus Clark (Decapoda: parastacidae)
Creators: name: Hamr, P
Publisher: name: University Of Tasmania
Year: 2023

description: The reproductive biology and life history of the Tasmanian freshwater crayfishes in the endemic genera Astacopsis and Parastacoides were studied in the field and laboratory from April 1985 to May 1987. A. gouldi and A. franklinii are open water species associated with riverine and lacustrine habitats from highlands to coastal plains. The burrowing, semiterrestrial P. tasmanicus occurs in wet heathlands, water courses and highland lakes in the wetter cooler, western half of the state. The three species were studied in representative, relatively undisturbed habitats. The habitats of all three species were typified by low water temperatures, high rainfall and fluctuating water levels. Reproductive morphology and anatomy of Astacopsis and Parastacoides was described in detail. Male and female gonads differ from those of northern hemisphere crayfishes, resembling anatomically the gonads of the Palinuridae. The male gonopores show considerable complexity and variation among genera. Female genitalia undergo significant changes in morphology at the onset of sexual maturity. Sexual dimorphism is developed to a greater degree in Astacopsis than in Parastacoides. Secondary sexual characters are more numerous in females of both genera and perform important functions in spawning and incubation of eggs. Data on seasonal reproduction, growth, population structure and density were obtained from regular sampling and mark recapture programs. Size at maturity and reproductive condition were determined by changes in reproductive morphology and gonad condition. In both genera males reach sexual maturity at a smaller size than females. Females, upon reaching maturity, exhibit a biennial breeding and molting cycle which is a unique strategy, apparently a result of the cooler climate conditions in Tasmania. In Astacopsis, mating and spawning take place in autumn, eggs are carried over winter, hatch mid to late the following summer and young remain attached until late summer to early autumn. Parastacoides mates and spawns in autumn, eggs are carried over winter, hatch early the following summer and postlarvae remain attached until mid summer. The larval development and morphology of Astacopsis and Parastacoides was described. Marked differences between the two genera were found and the \primitive\" larval development of Astacopsis differed significantly from that described for other freshwater crayfishes. Growth rates although faster in juveniles are relatively slow in adults of both genera. In reproductive adults of both sexes molting frequency is low (apparently biennial). This results in maturity being reached late and at a relatively large size as well as in overall longer life spans as compared to most other freshwater crayfishes."

Starra and trough tank : iron-formation-hosted gold-copper deposits of North-West Queensland, Australia
Creators: name: Davidson, GJ
Publisher: name: University Of Tasmania
Year: 2023

description: Starra and Trough Tank are stratabound Cu-Au deposits hosted by stratiform magnetite-hematite iron formation in the Mount Isa Eastern Succession, Australia. They are part of the rift-related Middle Proterozoic Mary Kathleen Group, deposited in a shallow to evaporitic setting, and subsequently deformed and metamorphosed. The location of Starra (consisting of 4 geographically separate orebodies), on the margin of a major Greenschist facies shear zone (ore metamorphism estimated at 500 - 550¬¨‚àû C, 3.5 - 4.5 kbar) has led to a more complex structural history than that experienced by surrounding rocks. Both structural/metamorphic and syngenetic ore genesis models have been proposed for the ores. Trough Tank is far less stained, but was metamorphosed to upper Amphibolite grade (680 - 720¬¨‚àû C, -4 kbar). Structural events in the Starra region are identified as (1) Starra Shear development during D1a extension, (2) peak-metamorphic D2(Main Phase) deformation, producing upright, north-trending, isoclinal folds, (3) retrogressional left lateral strikeslip on the Starra Shear, producing adjacent steeply-plunging medium-scale folds (D2(Late Phase)), (4) D3 northwest-trending fold and kink domains, and (5) D4 reverse movement on the Starra Shear and nearby Mount Dore Fault Zone. A new stratigraphic sub-division for the base of the Staveley Formation is proposed. Lowermost is the Harley Member, a strongly deformed chloritic unit with a tholeiitic tuff component. This is conformably overlain by the low-Nb-Zr-Y felsic Mariposa Creek Member, in turn conformably overlain by the Starra Iron-formation Member, and undifferentiated calcareous metasediments. To the south and east, the mineralised horizon strike-equivalents are massive hematitic ironstones, conglomerate-bearing ironstone, Hamersley-style banded iron formations (BLFs), and tourmalinites, all intercalated with shallow marine and fluvial-marine sediments. The local ore environment is interpreted as a deeper section of the basin.

Streptococcus pneumoniae

description: Initial reports in May 2009 of the novel influenza strain H1N1pdm estimated a case fatality rate (CFR) of 0.6%, similar to that of seasonal influenza. In July 2009, however, Argentina reported 3056 cases with 137 deaths, representing a CFR of 4.5%. Potential explanations for increased CFR included virus reassortment or genetic drift, or infection of a more vulnerable population. Virus genomic sequencing of 26 Argentinian samples representing both severe and mild disease indicated no evidence of reassortment, mutations associated with resistance to antiviral drugs, or genetic drift that might contribute to virulence. Furthermore, no evidence was found for increased frequency of risk factors for H1N1pdm disease. We examined nasopharyngeal swab samples (NPS) from 199 cases of H1N1pdm infection from Argentina with MassTag PCR, testing for 33 additional microbial agents. The study population consisted of 199 H1N1pdm-infected subjects sampled between 23 June and 4 July 2009. Thirty-nine had severe disease defined as death (n = 20) or hospitalization (n = 19); 160 had mild disease. At least one additional agent of potential pathogenic importance was identified in 152 samples (76%), including Streptococcus pneumoniae (n = 62); Haemophilus influenzae (n = 104); human respiratory syncytial virus A (n = 11) and B (n = 1); human rhinovirus A (n = 1) and B (n = 4); human coronaviruses 229E (n = 1) and OC43 (n = 2); Klebsiella pneumoniae (n = 2); Acinetobacter baumannii (n = 2); Serratia marcescens (n = 1); and Staphylococcus aureus (n = 35) and methicillin-resistant S. aureus (MRSA, n = 6). The presence of S. pneumoniae was strongly correlated with severe disease. S. pneumoniae was present in 56.4% of severe cases versus 25% of mild cases; more than one-third of H1N1pdm NPS with S. pneumoniae were from subjects with severe disease (22 of 62 S. pneumoniae-positive NPS, p = 0.0004). In subjects 6 to 55 years of age, the adjusted odds ratio (OR) of severe disease in the presence of S. pneumoniae was 125.5 (95% confidence interval [CI], 16.95, 928.72; p<0.0001). The association of S. pneumoniae with morbidity and mortality is established in the current and previous influenza pandemics. However, this study is the first to demonstrate the prognostic significance of non-invasive antemortem diagnosis of S. pneumoniae infection and may provide insights into clinical management.

description: The spectrum of the singly ionized sodium ion, Na II, has been photographed in the region between 350 Ɣ and 9000 Ɣ using as sources a condensed electrodeless discharge and a condensed spark in helium. Exposures were taken on a 3-meter normal-incidence vacuum grating spectrograph, on a 21-foot concave grating spectrograph, on a Hilger E-478 large interchangeable quartz and glass prism spectrograph, and Fabry-Perot interferometer. The term system has been revised and much extended. Five hundred and twenty-seven lines (with twenty doubly identified) are classified as combinations between sixty-two odd levels and seventy-one even levels. The ionization limits, 2s² 2p⁵(²P₃⁄₂) and 2s² 2p⁵ (²P₁⁄₂), have been redetermined as 381390.2 cm⁻¹ and 382756.6 cm⁻¹ (±2.0 cm⁻¹).

description: We have collected spectra of about 2000 red giant branch (RGB) stars in 19 Galactic globular clusters (GC) using FLAMES@VLT (about 100 star with GIRAFFE and about 10 with UVES, respectively, in each GC). These observations provide an unprecedented, precise, and homogeneous data-set of Fe abundances in GCs. We use it to study the cosmic scatter of iron and find that, as far as Fe is concerned, most GCs can still be considered mono-metallic, since the upper limit to the scatter in iron is less than 0.05 dex, meaning that the degree of homogeneity is better than 12%. The scatter in Fe we find seems to have a dependence on luminosity, possibly due to the well-known inadequacies of stellar atmospheres for upper-RGB stars and/or to intrinsic variability. It also seems to be correlated with cluster properties, like the mass, indicating a larger scatter in more massive GCs which is likely a (small) true intrinsic scatter. The 19 GCs, covering the metallicity range of the bulk of Galactic GCs, define an accurate and updated metallicity scale. We provide transformation equations for a few existing scales. We also provide new values of [Fe/H], on our scale, for all GCs in the Harris' catalogue.

description: The explosive growth of remote access electronic resources (e-resources) has added to the workload of libraries' cataloging departments. In response to this challenge, librarians developed various ways of providing access to electronic collections, but few dealt with the processing of free remote access e-resources, such as electronic books, Web sites, and databases. This paper will consider the various approaches taken by cataloging agencies to process Internet resources in all formats. It will then go on to describe Columbia University Libraries' approach to cataloging free Internet resources using a combination of selector input data, an automated form able to convert the information into MARC records, access level records, and cataloging expertise.

description: Background: Several coronaviruses establish persistent infections in vitro and in vivo, however it is unknown whether persistence is a feature of the severe acute respiratory syndorme coronavirus (SARS-CoV) life cycle. This study was conducted to investigate viral persistence. Methods: We inoculated confluent monolayers of Vero cells with SARS-CoV at a multiplicity of infection of 0.1 TCID50 and passaged the remaining cells every 4 to 8 days for a total of 11 passages. Virus was titrated at each passage by limited dilution assay and nucleocapsid antigen was detected by Western blot and immunofluoresence assays. The presence of viral particles in passage 11 cells was assessed by electron microscopy. Changes in viral genomic sequences during persistent infection were examined by DNA sequencing. Results: Cytopathic effect was extensive after initial inoculation but diminished with serial passages. Infectious virus was detected after each passage and viral growth curves were identical for parental virus stock and virus obtained from passage 11 cells. Nucleocapsid antigen was detected in the majority of cells after initial inoculation but in only 10%-40% of cells at passages 2-11. Electron microscopy confirmed the presence of viral particles in passage 11 cells. Sequence analysis at passage 11 revealed fixed mutations in the spike (S) gene and ORFs 7a-8b but not in the nucleocapsid (N) gene. Conclusions: SARS-CoV can establish a persistent infection in vitro. The mechanism for viral persistence is consistent with the formation of a carrier culture whereby a limited number of cells are infected with each round of virus replication and release. Persistence is associated with selected mutations in the SARS-CoV genome. This model may provide insight into SARS-related lung pathology and mechanisms by which humans and animals can serve as reservoirs for infection.

description: We present a deep circular polarization image of the Orion BN/KL nebula in the Ks band and correlations of circular polarization, linear polarization, and H-Ks color representing extinction. The image of circular polarization clearly reveals the quadrupolar structure around the massive star IRc2, rather than BN. H-Ks color is well correlated with circular polarization. A simple relation between dichroic extinction, color excess, circular and linear polarization is derived. The observed correlation between the Stokes parameters and the color excess agrees with the derived relation, and suggests a major contribution of dichroic extinction to the production of circular polarization in this region, indicating the wide existence of aligned grains.
