description: This thesis develops a framework for detecting invariance in diagnostic classification models in the presence of attribute hierarchies. The framework – called the measurement-invariance log-linear cognitive diagnostic model (MI-LCDM) – is an extension of the log-linear cognitive diagnostic model and provides a natural way to detect attribute (structural) invariance and measurement (item) invariance in a uniﬁed framework. The MI-LCDM uses notions of invariance from the factor analytic approach to test for group differences at the item and attribute level. In particular, the MI-LCDM generalizes the measurement model of the LCDM to allow for differential effects based on group membership to be tested. The structural model of MI-LCDM is parameterized as a Bayesian network, which allows attribute hierarchies to be modeled and tested for invariance. The proposed procedure is developed in the context of the Diagnosing Teachers’ Multiplicative Reasoning assessment. Results from the applied analysis indicate that the MI-LCDM is capable of detecting invariance at the attribute and item level. The analysis also revealed that a set of DTMR items exhibit partial invariance however the majority of items displayed evidence of full invariance.

description: This recording project presents original compositions for horn and piano written by Taiwanese composers. It offers a unique window into the artistic perspectives and creative voices of Taiwanese composers. Through collaborations with renowned artists like Wan-Yun Liang, Chi-Jou Cho, and Chang-An Chen, this project expands the existing repertoire while promoting Taiwanese composers on the international stage. The diverse array of pieces showcases the breadth of Taiwanese musical creativity, ranging from works influenced by traditional elements to modern experimental styles.This project, fulfilling a long-held dream of mine, showcases horn and piano pieces exclusively by Taiwanese composers. It encourages horn players to step out of their comfort zones and explore diverse genres, immersing themselves in rich music cultural expressions while bringing a fresh, innovative approach to the horn and piano literature. Each piece creates a dialogue between the composer and the musician, allowing for artistic expression while respecting the original creative intent. The recording process itself became an enriching learning experience as I carefully studied and interpreted the nuances of each unique composition.
description: This album's music crosses boundaries, encouraging communication and increasing understanding while preserving and enhancing the horn and piano repertoire by Taiwanese composers. Horn players can create a more comprehensive and engaging recital program by selectively blending pieces from this album with standard horn repertoire. This approach exposes horn players to a wide range of compositions while remaining connected to the core horn literature. Ultimately, by integrating local Taiwanese musical traditions into the horn and piano literature, this project facilitates cross-cultural exchange and promotes cross-cultural understanding.

description: Present composite spectra constructed from a sample of 242 150 Lyman a (Lyα) forest absorbers at redshifts 2.4 < z < 3.1 identified in quasar spectra from the Baryon Oscillation Spectroscopic Survey (BOSS) as part of Data Release 9 of the Sloan Digital Sky Survey III. We select forest absorbers by their flux in bins 138 km s-1 wide (approximately the size of the BOSS resolution element). We split these absorbers into five samples spanning the range of flux -0.05 ≤ F < 0.45. Tests on a smaller set of high-resolution spectra show that our three strongest absorption samples would probe circumgalactic regions (projected separation <300 proper kpc and |δ v| < 300 km s-1) in about 60 per cent of cases for very high signal-to-noise ratio. Within this subset, weakening Lyα absorption is associated with decreasing purity of circumgalactic selection once BOSS noise is included. Our weaker two Lyα absorption samples are dominated by the intergalactic medium. We present composite spectra of these samples and a catalogue of measured absorption features from H I and 13 metal ionization species, all of which we make available to the community. We compare measurements of seven Lyman series transitions in our composite spectra to single line models and obtain further constraints from their associated excess Lyman limit opacity. This analysis provides results consistent with column densities over the range 14.4 ≤ log(NHI) ≤ 16.45. We compare our measurements of metal absorption to a variety of simple single-line, singlephase models for a preliminary interpretation. Our results imply clumping on scales down to ̃30 pc and near-solar metallicities in the circumgalactic samples, while high-ionization metal absorption consistent with typical IGM densities and metallicities is visible in all samples.
Train tracks of pseudo-Anosov 3-braids and non-degenerate flype

description: In this thesis, we prove two results concerning properties of knots and braids. We focus on 3-braids which are isomorphic to the mapping class group of a 3-punctured disk, and their closures which form knots.
description: The first part of the thesis focuses on examining the slice-Bennequin inequality, which gives an upper bound for the self-linking number of a knot in terms of its four-ball genus. The $s$-Bennequin and $\tau$-Bennequin inequalities provide upper bounds on the self-linking number of a knot in terms of the Rasmussen $s$ invariant and the Ozsv\'ath-Szab\'o $\tau$ invariant. We exhibit examples in which the difference between self-linking number and four-ball genus grows arbitrarily large, whereas the $s$-Bennequin inequality and the $\tau$-Bennequin inequality are both sharp. This is the first known infinite sequence of braids with this property in the literature.
description: In the second part of the thesis, we study Agol cycles of pseudo-Anosov 3-braids using Farey sequences. An Agol cycle is a conjugacy class invariant of a pseudo-Anosov mapping class. We give a sufficient condition for two 3-braids to have equivalent or mirror equivalent Agol cycles and give infinitely many examples.
description: Since non-degenerate flypes play a significant role in knot theory, we also study behavior of Agol cycles of pseudo-Anosov 3-braids admitting flype moves.
Haunted armistice: The Great War, modern British literature, and the mourning of historical trauma.

description: The Armistice serves as the Great War's haunted point of closure in Britain. By combining literary and historical analysis with psychoanalysis and trauma theory, my interdisciplinary approach to the Great War enables a multifaceted exploration of the dynamics of unresolved mourning after catastrophic events through both general and historically specific modes of investigation. Chapter One addresses the unresolved crises of cultural and medical mediation occasioned by shell shock. I then suggest that contemporary scholarship which reformulates trauma and mourning after Freud's Beyond the Pleasure Principle (1920) effectively recalls the specters of the century's first massive trauma. Chapter Two foregrounds the scholar's participation in the cultural transmission and reception of catastrophic events through practical and theoretical formulations of trauma and mourning. In Chapter Three, diverse conceptualizations of mourning and survivorship are juxtaposed in illustration of the challenges which trauma poses to any unitary formulation of its aftermath. And adapting scholarship on the Second World War, Chapter Four considers the ways that secondary narratives of the Great War continue to engage the dynamics of historical trauma through an abiding preoccupation with the frontsoldier. In Part Two, by reclassifying the poems of Owen and Sassoon as poetic testimonies, Chapter Five privileges their urgent transmission and reception of harrowing experience and unresolved mourning. Chapter Six then contrasts the oppositional engagement of Woolf's Jacob's Room (1922) with official modes of memory-work configured after the Armistice by national commemorative sites such as the Cenotaph and the Tomb of the Unknown Warrior. In Chapter Seven, the postwar suicide of a veteran in Woolf's Mrs. Dalloway (1925) merely dramatizes that the specters of the War haunted the peace, a peace belied by numerous unresolved losses which contributed to the Second World War. Finally, Chapter Eight discusses Jones's In Parenthesis (1937) and its reconstruction of the haunted topography of the Somme, a landscape central to the War and its aftermath in Britain. In conclusion, I highlight the belated literature of historical trauma at the millennium as it continues to engage the cultural work of mourning initiated by the Great War generation.

description: Meeting global energy needs requires development of sustainable and affordable power options with minimal carbon footprint. As the world is moving away from traditional fossil-fuel-based energy sources, nuclear power emerges as a promising alternative providing reliable baseload energy without emission of greenhouse gases. While nuclear energy has been integrated in the United States energy grid since the late 1950s, the nuclear industry still faces challenges with the long-term storage and reprocessing of spent nuclear fuel, and legacy waste from the Manhattan project and plutonium production facilities. Such waste forms present a unique chemical challenge due to radiation fields inducing unexpected chemical reactions on the surface of stored materials. Radiolysis products on the surface of either spent nuclear fuel or stored nuclear waste are typically oxidized forms of uranium as peroxide- or carbonate-bearing alteration phases. As a result, there is a critical need to evaluate various mechanisms that lead to the formation of such alteration phases in the back-end of the nuclear fuel cycle, thus addressing potential challenges in the long-term storage or reprocessing efforts.
description: The objective of my thesis is to explore various synthetic pathways towards uranium alteration phases found on the surface of spent nuclear fuel and nuclear waste via generation or introduction of reactive oxygen species in the presence of hexavalent uranium. I have reported successful synthesis of uranyl peroxide species using: (i) in-situ generation of organic peroxide via autoxidation of benzaldehyde; (ii) photochemical uranyl-mediated H-abstraction in the solid state resulting in uranyl peroxide dimers; (iii/iv) mechanochemical reactivity of U(IV) and U(VI) oxides with solid alkali metal peroxides. Along with uranyl peroxide phases, we managed to (v) isolate the first uranyl superoxide (O2-●) compound that exhibits direct air capture of carbon dioxide, as well as (vi) demonstrate the behavior and thermodynamic stability of this uranyl superoxide material at elevated temperatures. This thesis presents a significant contribution to our understanding of reactions between reactive oxygen species (peroxide O22- and superoxide O2-●) and uranium, which provide a plausible mechanism for the formation of uranium-bearing alteration phases found on real-life samples of spent nuclear fuel and nuclear waste.

description: Background The capsaicin and heat responsive ion channel TRPV1 is expressed on trigeminal nociceptive neurons and has been implicated in the pathophysiology of migraine attacks. Here we investigate the efficacy of two TRPV1 channel antagonists in blocking trigeminal activation using two in vivo models of migraine. Methods Male Sprague–Dawley rats were used to study the effects of the TRPV1 antagonists JNJ-38893777 and JNJ-17203212 on trigeminal activation. Expression of the immediate early gene c-fos was measured following intracisternal application of inflammatory soup. In a second model, CGRP release into the external jugular vein was determined following injection of capsaicin into the carotid artery. Results Inflammatory up-regulation of c-fos in the trigeminal brain stem complex was dose-dependently and significantly reduced by both TRPV1 antagonists. Capsaicin-induced CGRP release was attenuated by JNJ-38893777 only in higher dosage. JNJ-17203212 was effective in all doses and fully abolished CGRP release in a time and dose-dependent manner. Conclusion Our results describe two TRPV1 antagonists that are effective in two in vivo models of migraine. These results suggest that TRPV1 may play a role in the pathophysiological mechanisms, which are relevant to migraine.
Temperature dependence of the electrical resistivity in amorphous metallic alloys.

Subjects: subject: Physics, Electricity and Magnetism.

description: The purpose of this study is to investigate the conduction electrons' interaction mechanisms over the wide temperature range in order to find possible deviations from the existing theories. The temperature dependence of the electrical resistivity of two scattering systems, the crystalline and the amorphous, in the range of 1.7--300 K is studied. In the pure crystalline metals, the nearly-free-electron model can qualitatively and quantitatively account for the temperature dependence of the electrical resistivity. In the low-temperature range, the electron-electron scattering is the dominant scattering mechanism. Above the Debye temperature, the phonon-electron scattering is the dominant scattering mechanism. The temperature dependence of the electrical resistivity for the amorphous metallic alloys can be described qualitatively by the Ziman model. The scattering mechanism of the conduction electrons of the samples can be categorized in the weak scattering limit regime. A small, but significant correction must be added to the Ziman model in order to account for the additional scattering contributions that exist in the wide temperature range. In the very-low-temperature range the electron-electron interaction effect is the major correction to the temperature dependence of the electrical resistivity. In the low-temperature range, the weak localization effect is the major correction to the temperature dependence of the electrical resistivity. In the high-temperature range, the temperature dependence of the electrical resistivity is linear with a small but significant correction. For some samples the magnetic contribution is the major correction, for others the multiphonon scattering is the major correction. For the resistivity minima at temperatures below 20 K could be due to the Kondo effect. A more plausible explanation, however, is the electron-electron interaction effect. The Ziman model with the proper corrections is found to be an adequate and successful model in accounting for the temperature dependence of the electrical resistivity of all of the studied amorphous metallic alloys.

Sleep and sleep loss on hippocampal memory and plasticity

description: Sleep facilitates memory storage, and sleep loss leads to impairments in memory, especially for types of memory that are dependent on the hippocampus. The importance of sleep for memory consolidation has been well documented, but there are questions about the mechanisms underlying this sleep-dependent process. Many labs have used different methods to try and identify these mechanisms but have achieved conflicting results. This might be because many widely used methods of sleep deprivation are reliant on exogenous stimulation to keep the animals awake, and that external stimulation is capable of producing its own effects on memory and plasticity, independent of the impact on sleep. Previous work from the lab has used exogenous methods of sleep deprivation to reveal that cAMP signaling may be the mechanism for memory consolidation in sleep. Reduced cAMP signaling cascades explain many of the deficits that are observed in sleep deprivation, including memory problems and impaired hippocampal plasticity. There remain questions about where and when these deficits initiate in the hippocampus, what components of the pathway can be rescued, and if there are differences in how the stages of sleep contribute to memory consolidation and plasticity. To address the role of sleep in memory and plasticity, this proposal aims to dive deep into the role of cAMP signaling, and study both the effects of decreasing sleep, and increasing the amount of time spent in a specific sleep stage using endogenous neural circuits to manipulate sleep/wake in the absence of external stimulation.

description: Voice over IP (VoIP), the transmission of voice over an IP network, is gaining much momentum in the industry. Its benefits over conventional telephony are numerous, but the impairments present on an IP network make implementing such a system quite a challenge. In this thesis, Voice over IP (VoIP) will be studied with a particular emphasis on the speech compression algorithms used in such a system. The desired characteristics of a speech compression algorithm for VoIP will be analyzed. These characteristics will then be used to judge how appropriate are some existing standards of speech compression algorithms for VoIP. A promising speech compression algorithm resulting from this analysis, ITU-T G.729A, will be used to analyze its ability to recover from packet loss since this is one of the main impairments of an IP network. Finally, a novel method to improve the performance of this algorithm in presence of packet loss will be described with results.

description: Pulmonary tuberculosis (PTB) results in lung functional impairment and there are no surrogate markers to monitor the extent of lung involvement. We investigated the clinical significance of S100A12 and soluble receptor for advanced glycation end-products (sRAGE) for predicting the extent of lung involvement. We performed an observational study in India with 119 newly diagnosed, treatment naïve, sputum smear positive, HIV-negative PTB patients and 163 healthy controls. All patients were followed-up for six months. Sociodemographic variables and the serum levels of S100A12, sRAGE, esRAGE, HMGB-1, TNF-α, IFN-γ and CRP were measured. Lung involvement in PTB patients was assessed by chest radiography. Compared with healthy controls, PTB patients had increased serum concentrations of S100A12 while sRAGE was decreased. S100A12 was an independent predictor of disease occurrence (OR 1.873, 95%CI 1.212–2.891, p = 0.004). Under DOTS therapy, S100A12 decreased significantly after 4 months whereas CRP significantly decreased after 2 months (p

description: We describe the structural and kinematic properties of the first compact stellar systems discovered by the Archive of Intermediate Mass Stellar Systems project. These spectroscopically confirmed objects have sizes (~6 < Re [pc] < 500) and masses (~2 × 106 < M*/M⊙< 6 × 109) spanning the range of massive globular clusters, ultracompact dwarfs (UCDs) and compact elliptical galaxies (cEs), completely filling the gap between star clusters and galaxies. Several objects are close analogues to the prototypical cE, M32. These objects, which are more massive than previously discovered UCDs of the same size, further call into question the existence of a tight mass-size trend for compact stellar systems, while simultaneously strengthening the case for a universal 'zone of avoidance' for dynamically hot stellar systems in the mass-size plane. Overall, we argue that there are two classes of compact stellar systems (1) massive star clusters and (2) a population closely related to galaxies. Our data provide indications for a further division of the galaxy-type UCD/cE population into two groups, one population that we associate with objects formed by the stripping of nucleated dwarf galaxies, and a second population that formed through the stripping of bulged galaxies or are lower mass analogues of classical ellipticals. We find compact stellar systems around galaxies in low- to high-density environments, demonstrating that the physical processes responsible for forming them do not only operate in the densest clusters.

Accumulation of persistent organic pollutants in terrestrial vegetation from the Canadian Rocky Mountains.

description: This thesis examines the accumulation of persistent organochlorine compounds in Canadian mountain environments through the sampling of air and coniferous vegetation along a 1430-meter elevation gradient in the Canadian Rocky Mountains. Results showed that lower temperatures encountered in high altitudes favor the accumulation of chemicals with higher volatility in vegetation. Air concentrations further suggest that the reason for this accumulation in elevated areas is increased atmospheric deposition from distant sources and not from temperature-induced revolatilization from local terrestrial surfaces. Seasonal decreases in plant concentrations indicate evaporative processes, and volatilization from vegetation was confirmed by calculated fugacity gradients. However, volatilization contributes very little to air concentrations and the subsequent fractionation upslope, which appears to be dominated by long-range transport. Multivariate analysis revealed that, in addition to cooler temperatures, other environmental conditions common to mountain ecosystems, such as elevated precipitation and lower pressure, promote chemical deposition onto vegetation.

Subjects: subject: Physics, Nuclear.

description: At the present time, the meaning of the cluster model and what is meant by clustering in actual nuclei has not been fully clarified. It is thought that some progress is made here in an understanding of clustering in nuclei. Along with defining the cluster model, the amount of ad hoc involved in the choice of a certain cluster model of a nucleus is given. Also presented here, is a quantitative measure of the amount of clustering occurring in the nucleus. A calculation of this measure of the degree of clustering in the Be 8 nucleus is performed with success. It is demonstrated that Be 8 is slightly ellipsoidal in shape and much less dense than a free alpha particle, The radius of the alpha particles within Be8 is calculated and compared with the radius of a free alpha particle. The separation of the alpha particles is found to be much less than the magnitude of the alpha cluster radius. This investigation also revealed certain new mathematical and physical properties of the cluster model.

description: The fatty liver index (FLI) predicts fatty liver by using BMI, waist circumference, γ-glutamyltransferase and triglycerides. We investigated the association between the FLI and the risk of type 2 diabetes and evaluated to what extent single FLI components contribute to the diabetes risk. We analysed a case-cohort study (random sub-cohort: 1922; incident cases: 563) nested within the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam study. The proportion of exposure effect (PEE) explained by single FLI components was evaluated and effect decomposition using inverse probability weighting (IPW) was applied. Women and men with a FLI ≥60 compared to those with a FLI <30 had a multivariable-adjusted Hazard Ratio (HR) of 17.6; 95% confidence interval (CI) 11.1-28.0 and HR: 10.9; 95% CI 6.22-19.2, respectively. Adjustment for BMI or waist circumference attenuated this association in men [PEEBMI (95% CI) = 53.8% (43.9%-65.8%); PEEwaist (95% CI) = 54.8% (44.2%-68.8%)]. In women, adjustment for waist circumference attenuated the association to a lesser degree than in men [PEEwaist (95% CI) = 31.1%; (21.9%-43.1%)] while BMI had no appreciable effect [PEEBMI (95% CI) = 11.0% (2.68%-21.0%)]. γ-glutamyltransferase and triglycerides showed only a small attenuation in women [PEEGGT(95% CI) = 3.11% (-0.72%-4.48%); PEETG (95% CI) = 6.36% (3.81%-9.92%)] and in men [PEEGGT = 0%; PEETG (95% CI) = 6.23% (2.03%-11.8%)]. In women, the total effect was decomposed into a direct effect and 4 indirect effects (HRBMI = 1.10; HRwaist = 1.28; HRGGT = 0.97 and HRTG = 1.03). In men, the 4 indirect effects were HRBMI = 1.25; HRwaist = 1.29; HRGGT = 0.97 and HRTG = 0.99. These data suggest that the FLI, as a proxy for fatty liver, is associated with risk of type 2 diabetes. This association is only partly explained by standard estimates of overall and abdominal body fatness, particularly among women.

description: In this thesis, the environmental values of Canada and Sweden as they are embodied in the forest policy of these two countries are examined within the framework of Beck's theory of the risk society to discover whether there is evidence to support Beck's theory of the evolution of industrialised countries from primary to reflexive modernisation. The historical, cultural and social-structural conditions underlying the development of Canadian and Swedish forest policy are also investigated in order to situate those policies in their historical and comparative context.

description: Antibiotic resistance is projected as one of the greatest threats to human health in the future and hence alternatives are being explored to combat resistance. Antimicrobial peptides (AMPs) have shown great promise, because use of AMPs leads bacteria to develop no or low resistance. In this review, we discuss the diversity, history and the various mechanisms of action of AMPs. Although many AMPs have reached clinical trials, to date not many have been approved by the US Food and Drug Administration (FDA) due to issues with toxicity, protease cleavage and short half-life. Some of the recent strategies developed to improve the activity and biocompatibility of AMPs, such as chemical modifications and the use of delivery systems, are also reviewed in this article.

This coprocessor is intended to work in microprocessor-based embedded systems where it is seen as an 8-bit memory mapped device by the system microprocessor. The coprocessor architecture is implemented and simulated using VHDL.

description: We analyze the star-forming and structural properties of 45 massive (log(M/M⊙) >10) compact star-forming galaxies (SFGs) at 2 < z < 3 to explore whether they are progenitors of compact quiescent galaxies at z ∼ 2. The optical/NIR and far-IR Spitzer/Herschel colors indicate that most compact SFGs are heavily obscured. Nearly half (47%) host an X-ray-bright active galactic nucleus (AGN). In contrast, only about 10% of other massive galaxies at that time host AGNs. Compact SFGs have centrally concentrated light profiles and spheroidal morphologies similar to quiescent galaxies and are thus strikingly different from other SFGs, which typically are disk-like and sometimes clumpy or irregular. Most compact SFGs lie either within the star formation rate (SFR)-mass main sequence (65%) or below it (30%), on the expected evolutionary path toward quiescent galaxies. These results show conclusively that galaxies become more compact before they lose their gas and dust, quenching star formation. Using extensive HST photometry from CANDELS and grism spectroscopy from the 3D-HST survey, we model their stellar populations with either exponentially declining (τ) star formation histories (SFHs) or physically motivated SFHs drawn from semianalytic models (SAMs). SAMs predict longer formation timescales and older ages ∼2 Gyr, which are nearly twice as old as the estimates of the τ models. Both models yield good spectral energy distribution fits, indicating that the systematic uncertainty in the age due to degeneracies in the SFH is of that order of magnitude. However, SAM SFHs better match the observed slope and zero point of the SFR-mass main sequence. Contrary to expectations, some low-mass compact SFGs (log(M/M⊙) =10-10.6) have younger ages but lower specific SFRs than that of more massive galaxies, suggesting that the low-mass galaxies reach the red sequence faster. If the progenitors of compact SFGs are extended SFGs, state-of-the-art SAMs show that mergers and disk instabilities (DIs) are both able to shrink galaxies, but DIs are more frequent (60% versus 40%) and form more concentrated galaxies. We confirm this result via high-resolution hydrodynamic simulations.

description: Background: Accumulation mode particles (AMP) are formed from engine combustion and make up the inhalable vapour cloud of ambient particulate matter pollution. Their small size facilitates dispersal and subsequent exposure far from their original source, as well as the ability to penetrate alveolar spaces and capillary walls of the lung when inhaled. A significant immuno-stimulatory component of AMP is lipopolysaccharide (LPS), a product of Gram negative bacteria breakdown. As LPS is implicated in the onset and exacerbation of asthma, the presence or absence of LPS in ambient particulate matter (PM) may explain the onset of asthmatic exacerbations to PM exposure. This study aimed to delineate the effects of LPS and AMP on airway inflammation, and potential contribution to airways disease by measuring airway inflammatory responses induced via activation of the LPS cellular receptor, Toll-like receptor 4 (TLR-4). Methods: The effects of nebulized AMP, LPS and AMP administered with LPS on lung function, cellular inflammatory infiltrate and cytokine responses were compared between wildtype mice and mice not expressing TLR-4. Results: The presence of LPS administered with AMP appeared to drive elevated airway resistance and sensitivity via TLR-4. Augmented TLR4 driven eosinophilia and greater TNF-α responses observed in AMP-LPS treated mice independent of TLR-4 expression, suggests activation of allergic responses by TLR4 and non-TLR4 pathways larger than those induced by LPS administered alone. Treatment with AMP induced macrophage recruitment independent of TLR-4 expression. Conclusions: These findings suggest AMP-LPS as a stronger stimulus for allergic inflammation in the airways then LPS alone.

description: As our society experiences faster and faster rates of progress, technology becomes available to solve the most complicated engineering problems. These new technologies allow to build much more complex systems than what current methodologies allow to design in an orderly and structured manner, which is necessary to permit easy system expansions, upgrading and maintenance. This is particularly true in the case of embedded and real-time systems, which have to exhibit correct functional and temporal behaviors. This thesis focuses on a design methodology for embedded systems that is intended to be used by the application specialists, instead of the computer specialists. This avoids the problems generated when interactions are necessary between the two specialists and when the design is done by those who are unfamiliar with the application, lacking detailed knowledge of the system requirements. The methodology is based on the multiactivity paradigm and uses two system prototypes: the Specification Prototype, which is a prototype of the behavioral and functional requirements specifications; and the Design Prototype, which is a prototype of the design specifications and can be used to observe its temporal characteristics, to see whether the system will meet the required timing constraints. Finally, the methodology is exemplified and its feasibility demonstrated through various tests that were run using a simulator.
Conditional inactivation of the BRCA1 tumour suppressor gene in the mouse ovarian surface epithelium in vitro and in vivo

description: Epithelial ovarian cancer (EOC) is thought to arise from the ovarian surface epithelium (OSE); however the molecular events underlying this transformation are poorly understood. Germline mutations in the BRCA1 tumor suppressor gene result in a significantly increased risk of developing EOC and a large proportion of sporadic EOCs display some sort of BRCA1 dysfunction. Using mice with conditional expression of Brca1, we inactivated Brca1 in the murine OSE and demonstrate that this inactivation results in the development of preneoplastic changes, such as hyperplasia, epithelial invaginations, and inclusion cysts, which arise earlier and are more numerous than in control ovaries. These changes resemble the premalignant lesions that have been reported in human prophylactic oophorectomy specimens from women with BRCA1 germline mutation. While tumourigenesis was not observed when Brca1 was inactivated on its own, it was found that inactivation of Brca1 accelerated tumour progression in animals in which the p53 tumour suppressor had also been inactivated in the OSE, an effect that was not observed with concomitant inactivation of the Rb tumour suppressor gene. Inactivation of Brca1 in primary cultures of murine OSE cells led to a suppression of proliferation due to increased apoptosis that could be rescued by concomitant inactivation of p53 and/or Rb, however only concomitant inactivation of p53 led to the ability of Brca1-deficient MOSE cells to grow in an anchorage-independent manner. Brca1-deficient MOSE cells displayed an increased sensitivity to the DNA damaging agent cisplatin and were modestly less sensitive to the mitotic spindle poison paclitaxel, effects which could both be modulated via inactivation of p53 and/or Rb. These observations indicate that loss of function of Brca1 in OSE cells impacts both cellular growth control and DNA-damage repair which results in altered cell behavior manifested as morphological changes in vivo that arise earlier and are more numerous than what can be attributed to ageing. It is postulated that loss of Brca1 in the OSE renders these cells susceptible to further genetic aberrations such as loss of other tumour suppressors or activation of oncogenes that could lead to transformation and tumourigenesis.

description: Using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope, the COS Science Team has conducted a high signal-to-noise survey of 14 bright QSOs. In a previous paper, these far-UV spectra were used to discover 14 'warm' (T ≥ 105 K) absorbers using a combination of broad Lyα and broad O VI absorptions. A reanalysis of a few of this new class of absorbers using slightly relaxed fitting criteria finds as many as 20 warm absorbers could be present in this sample. A shallow, wide spectroscopic galaxy redshift survey has been conducted around these sight lines to investigate the warm absorber environment, which is found to be spiral-rich groups or cluster outskirts with radial velocity dispersions σ = 250-750 km s-1. While 2σ evidence is presented favoring the hypothesis that these absorptions are associated with the galaxy groups and not with the individual, nearest galaxies, this evidence has considerable systematic uncertainties and is based on a small sample size so it is not entirely conclusive. If the associations are with galaxy groups, the observed frequency of warm absorbers ( = 3.5-5 per unit redshift) requires them to be very extended as an ensemble on the sky (1 Mpc in radius at high covering factor). Most likely these warm absorbers are interface gas clouds whose presence implies the existence of a hotter (T 106.5 K), diffuse, and probably very massive (>1011 M )⊙ intra-group medium which has yet to be detected directly.
