description: Circumstellar disks are thought to experience a rapid "transition" phase in their evolution that can have a considerable impact on the formation and early development of planetary systems. We present new and archival high angular resolution (0.3" = 40-75 AU) Submillimeter Array (SMA) observations of the 880 micron dust continuum emission from 12 such transition disks in nearby star-forming regions. In each case, we directly resolve a dust-depleted disk cavity around the central star. Using radiative transfer calculations, we interpret these dust disk structures in a homogeneous, parametric model framework by reproducing their SMA visibilities and SEDs. The cavities in these disks are large (R_cav = 15-73 AU) and substantially depleted of small (~um-sized) dust grains, although their mass contents are still uncertain. The structures of the remnant material at larger radii are comparable to normal disks. We demonstrate that these large cavities are common among the millimeter-bright disk population, comprising at least 20% of the disks in the bright half of the millimeter luminosity (disk mass) distribution. Utilizing these results, we assess some of the physical mechanisms proposed to account for transition disk structures. As has been shown before, photoevaporation models do not produce the large cavity sizes, accretion rates, and disk masses representative of this sample. It would be difficult to achieve a sufficient decrease of the dust optical depths in these cavities by particle growth alone: substantial growth (to meter sizes or beyond) must occur in large (tens of AU) regions of low turbulence without also producing an abundance of small particles. Given those challenges, we suggest instead that the observations are most commensurate with dynamical clearing due to tidal interactions with low-mass companions --young brown dwarfs or giant planets on long-period orbits.

description: We have measured the neutron electric dipole moment using spin rotation in a non-centrosymmetric crystal. Our result is d_n = (2.5 +- 6.5(stat) +- 5.5(syst)) 10^{-24} e cm. The dominating contribution to the systematic uncertainty is statistical in nature and will reduce with improved statistics. The statistical sensitivity can be increased to 2 10^{-26} e cm in 100 days data taking with an improved setup. We state technical requirements for a systematic uncertainty at the same level.

description: We describe a recently introduced principle of relative locality which we propose governs a regime of quantum gravitational phenomena accessible to experimental investigation. This regime comprises phenomena in which $\hbar$ and $G_N$ may be neglected, while their ratio, the Planck mass $M_p =\sqrt{\hbar / G_N}$, is important. We propose that $M_p$ governs the scale at which momentum space may have a curved geometry. We find that there are striking consequences for the concept of locality. The description of events in spacetime now depends on the energy used to probe it. But there remains an invariant description of physics in phase space. There is furthermore a reasonable expectation that the geometry of momentum space can be measured experimentally using astrophysical observations.

The genetics of adaptation and speciation in threespine stickleback species pairs (Gasterosteus aculeatus species complex)
Creators: name: Conte, Gina Louise
Publisher: name: University of British Columbia
Year: 2015

description: Ecological speciation appears to be a common process by which new species arise and the genetics underlying the process can substantially affect its outcome. Replicate ‘benthic and limnetic’ pairs of threespine stickleback species are an ideal system with which to study the genetics underlying ecological speciation. My first question was: what genetic mechanisms link divergent natural selection to reproductive isolation during ecological speciation? In chapter 2, I present an experiment designed to determine what genetic mechanism links divergent selection on body size to assortative mating by body size in the Paxton Lake species pair. I found that body size functions as a mate signal trait and determines female mate preference via phenotype matching. This implies that genes under divergent selection are the same as those underlying both components of assortative mating, a mechanism that should facilitate ecological speciation with gene flow. My second question was: what is the genetic architecture of adaptation during ecological speciation? In chapter 4, I used QTL mapping to discover the genetic architecture underlying a large number of parallel morphological differences in the Paxton and Priest Lake species pairs and found it to be polygenic and widespread throughout the genome in both. This suggests that many loci underlying ecologically important traits have diverged (and/or divergence has persisted) during ecological speciation despite homogenizing gene flow. My third question was: how predictable are the genetics of adaptation during ecological speciation and in general? Chapters 3 and 4 describe the first studies to quantitatively address this question. In chapter 4, I found that about 50% of QTL for parallel morphological differences are parallel in the two species pairs. Also, on average, the proportional similarity of QTL use underlying individual traits is about 0.4. In Chapter 3, I present the results of a meta-analysis of the genetics underlying repeated phenotypic evolution in natural populations. Using an impartial literature review, I found that the average probability of gene reuse was 0.32 - 0.55. I also found that the probability of gene reuse declined with increasing age of the taxa compared.

description: Zipf's law states that the number of firms with size greater than S is inversely proportional to S. Most explanations start with Gibrat's rule of proportional growth but require additional constraints. We show that Gibrat's rule, at all firm levels, yields Zipf's law under a balance condition between the effective growth rate of incumbent firms (which includes their possible demise) and the growth rate of investments in entrant firms. Remarkably, Zipf's law is the signature of the long-term optimal allocation of resources that ensures the maximum sustainable growth rate of an economy.

description: A complex Hilbert space of dimension six supports at least three but not more than seven mutually unbiased bases. Two computer-aided analytical methods to tighten these bounds are reviewed, based on a discretization of parameter space and on Grobner bases. A third algorithmic approach is presented: the non-existence of more than three mutually unbiased bases in composite dimensions can be decided by a global optimization method known as semidefinite programming. The method is used to confirm that the spectral matrix cannot be part of a complete set of seven mutually unbiased bases in dimension six.

description: In this short note, we study the geometry of the eigenvariety parametrising p-adic automorphic forms for GL(1) over a number field K, as constructed by Buzzard. We show that if K is not totally real and contains no CM subfield, points in this space arising from classical automorphic forms (i.e. algebraic Grossencharacters of K) are not Zariski-dense in the eigenvariety (as a rigid space); but the eigenvariety posesses a natural formal scheme model, and the set of classical points is Zariski-dense in the formal scheme. We also sketch the theory for GL(2) over an imaginary quadratic field, following Calegari and Mazur, emphasising the strong formal similarity with the case of GL(1) over a general number field.

Producing pedagogy : examining masculinities, femininities and sexualities in/through visual digital media
Creators: name: Moore, Shannon D. M.
Publisher: name: University of British Columbia
Year: 2014

description: This dissertation explores the methodological, theoretical and pedagogical tensions of an eight-month ethnographic study within a Film classroom. Drawing on participant observation, group film discussions, and participant produced films, the chapters that follow consider the ways in which youth inhabit and make sense of masculinities/femininities and sexualities as conveyed in visual digital media, and how the very categories of youth, gender and media are constructed and disrupted in the process of video production—and through the process of research. This project challenges the notion that research captures ‘reality’ through meticulous data collection and analysis, and instead considers the way that ethnography produces the very materiality it attempts to represent (Britzman, 1995). Although methodologically encouraged by theories that promote “getting lost” (Lather, 2007), there were many moments in which modernist assumptions, institutional and discursive expectations, regulated the process of conducting and representing the research. Following a lineage of theorists who challenge the assumptions and expectations that burden empirical research (Britzman, 1995; Lather, 2006; Talburt, 2004; Youdell, 2005; 2006; 2009) and who trouble the notion of ‘what counts as data’ (Pitt & Britzman, 2003), the methodological tensions and theoretical incongruencies that arose through this project informed, and became, data. The articulation and analysis of these tensions, idiosyncrasies, and ‘failings’ as data, contributes to conversations about enacting troubling, and troubled research. Further to methodological failings, this project invites discussions of uncertainty, loss, and unknowability in order to provoke the pervasive ‘cultural myths’ of teacher (Britzman, 2003), and to contribute to larger theoretical discussions of pedagogy. Drawing on popular media and digital video production in/through/as pedagogy, this research considers the ways each might be reconceptualized. In particular, the ways in which popular media and digital video production practices invite the body and senses in/as pedagogy (Ellsworth, 2005). However, like the regulatory process of research, pervasive modernist discourses of teacher (Britzman, 2003), education (Popkewitz, 1997), knowledge, teaching and learning (Ellsworth, 2005) may restrict the pedagogical possibilities of popular media and digital video production within educational contexts. This regulatory parallel is indicative of the tangles of methodology and pedagogy amidst these chapters

description: We perform numerical simulations of the gravitational collapse of a k-essence scalar field. When the field is sufficiently strongly gravitating, a black hole forms. However, the black hole has two horizons: a light horizon (the ordinary black hole horizon) and a sound horizon that traps k-essence. In certain cases the k-essence signals can travel faster than light and the sound horizon is inside the light horizon. Under those circumstances, k-essence signals can escape from the black hole. Eventually, the two horizons merge and the k-essence signals can no longer escape.

description: We study the nonlinear evolution of density perturbations in cosmologies where the late-time accelerated expansion is driven by a quintessence field with vanishing speed of sound. For these models matter and quintessence perturbations are comoving and it is possible to write a single continuity equation for the total density fluctuations given by a weighted sum of the two components. Including the Euler equation for the common velocity field we solve the evolution equations for the nonlinear, total density power spectrum in the Time-Renormalization Group approach. In fact any cosmological observable is directly related by gravity only to the total density perturbations, with the two components being individually unobservable. We show that the clustering of quintessence perturbations induces small corrections with respect to the nonlinear evolution of power spectrum in smooth quintessence models described by the same equation of state. Such small corrections, however, contrast with the large effect of a vanishing speed of sound on the linear growth function at low redshift. For this reason, models with the same normalization of the linear density power spectrum can present significantly different nonlinear corrections depending on the value of the sound speed. Although such differences vanish in the w \rightarrow -1, ΛCDM limit, we argue that the relation between linear and nonlinear growth of structures should be properly taken into account in constraining models with inhomogeneous dark energy.

description: We examine the parametrization of the e+e- -> omega pi0 cross section in the vicinity of the phi resonance and the extraction of the branching fraction of the isospin violating process phi -> omega pi0 from experimental data.

The latter is two orders of magnitude higher than the former, which is the commonly accepted one.

description: We have investigated the main scattering mechanisms affecting mobility in graphene nanoribbons using detailed atomistic simulations. We have considered carrier scattering due to acoustic and optical phonons, edge roughness, single defects, and ionized impurities, and we have defined a methodology based on simulations of statistically meaningful ensembles of nanoribbon segments. Edge disorder heavily affects mobility at room temperature in narrower nanoribbons, whereas charged impurities and phonons are hardly the limiting factors. Results are favorably compared to the few experiments available in the literature.

Cryptographic role-based access control for secure data storage in cloud systems

subject: Other education not elsewhere classified

description: With the rapid increase in the amount of digital information that needs to be stored, there has been a growing trend in recent times to store data in the cloud because ofthe benefits it provides such as on-demand access and scalability. Cloud data storage raises the important security issue of how to control and prevent unauthorised access to data stored in the cloud. Access control is required to specify who can create the access policies as well as to determine the access mechanisms needed to control access to the stored data. One well-known access control model is the role-based access control (RBAC) model, which provides flexible controls and security management by having two mappings, users to roles and roles to privileges on data objects.
 We propose role-based encryption (RBE) schemes, which integrate cryptographic techniques with RBAC models, to enforce RBAC policies for data stored in the cloud. Using RBE schemes, the owners of data can encrypt it in such a way that only users with appropriate roles as specified by the access policy can decrypt and view the content of the data. We then describe the design of a secure RBE-based hybrid cloud storage architecture as well as a practical implementation of the proposed RBE-based architecture and its performance results.
 In large-scale RBAC systems, decentralising the administration tasks is an important issue as it is usually impractical to centralise the task of managing these users and permissions, and their relationships with roles. We propose a cryptographic administrative model AdC-RBAC to manage and enforce role-based access policies for the RBE schemes in large-scale cloud systems. The AdC-RBAC model uses cryptographic techniques to ensure that administrative tasks such as user, permission, and role management are performed only by authorised administrative roles.
 We have also demonstrated the suitability of the proposed RBE schemes and the developed architecture in two practical applications, one involving secure data storage in the cloud for a banking organisation and the other concerned with secure storage of patient-centric health records in the cloud.
 The issue of trust is critical in cloud storage systems and it is necessary to address explicitly trust issues in the enforcement of access policies in cloud data storage as often implicit assumptions are made that the various system entities behave properly. We have developed trust models that can help to reason about the behaviour of users, data owners and role managers, taking into account role hierarchy and permission inheritance. We then describe the design of trust-enhanced secure cloud data storage systems integrating trust models and RBE schemes, which reduce risk and improve the quality of cloud storage services.

description: Thermal emission from Kuiper Belt object (136108) Haumea was measured with Herschel-PACS at 100 and 160 micrometers for almost a full rotation period. Observations clearly indicate a 100-micrometer thermal lightcurve with an amplitude of a factor of ~ 2, which is positively correlated with the optical lightcurve. This confirms that both are primarily due to shape effects. A 160-micrometer lightcurve is marginally detected. Radiometric fits of the mean Herschel- and Spitzer- fluxes indicate an equivalent diameter D ~ 1300 km and a geometric albedo p_v ~ 0.70-0.75. These values agree with inferences from the optical lightcurve, supporting the hydrostatic equilibrium hypothesis. The large amplitude of the 100-micrometer lightcurve suggests that the object has a high projected a/b axis ratio (~ 1.3) and a low thermal inertia as well as possible variable infrared beaming. This may point to fine regolith on the surface, with a lunar-type photometric behavior. The quality of the thermal data is not sufficient to clearly detect the effects of a surface dark spot.

description: For reasons of both electoral competitiveness and democratic legitimacy, political parties in diverse democracies increasingly compete for the votes of immigrant and ethnic minority voters. A considerable literature has examined the effects of electoral advertising on the partisanship and turnout of targeted groups. Little attention has been given, however, to the nature of the representational offers contained in advertising that targets ethnic minorities. Do party advertisements offer descriptive representation, by featuring ethnic candidates? Do they offer geographic representation, by focusing on districts where ethnic minorities live? Do they offer to represent ethnic minorities’ specific interests or experiences? Where ethnic minorities are internally diverse, what efforts do parties make to address such diversity in their advertising? How parties answer these questions affects the scope and inclusivity of the representational offers extended to ethnic minority voters, with consequences for their political inclusion and representation. We examine how these questions have been answered in New Zealand, a country characterised by high rates of inward migration and the enfranchisement of resident non-citizens. Using data from a novel study of New Zealand political parties’ election advertisements targeting Chinese voters, we assess the quantity and character of representational offers made to this internally diverse minority group. Our findings suggest that, even as the main political parties are increasingly making specific representational offers to Chinese New Zealanders, these offers vary across the political spectrum in their quantity, scope and inclusiveness.

description: We investigate energy dissipation associated with the motion of the scalar condensate in a holographic superconductor model constructed from the charged scalar field coupled to the Maxwell field. Upon application of constant magnetic and electric fields, we analytically construct the vortex flow solution, and find the vortex flow resistance near the second-order phase transition where the scalar condensate begins. The characteristic feature of the non-equilibrium state agrees with the one predicted by the time-dependent Ginzburg-Landau(TDGL) theory. We evaluate the kinetic coefficient in the TDGL equation along the line of the second-order phase transition. At zero magnetic field, the other coefficients in the TDGL equation are also evaluated just below the critical temperature.

description: Using archival Hubble Space Telescope (HST) imaging data, we report the multiband photometric properties of 13 ultraluminous X-ray sources (ULXs) that have a unique compact optical counterpart. Both magnitude and color variation are detected at time scales of days to years. The optical color, variability, and X-ray to optical flux ratio indicate that the optical emission of most ULXs is dominated by X-ray reprocessing on the disk, similar to that of low mass X-ray binaries. For most sources, the optical spectrum is a power-law, $F_ν \propto ν^α$ with $α$ in the range 1.0 to 2.0 and the optically emitting region has a size on the order of 1e12 cm. Exceptions are NGC 2403 X-1 and M83 IXO 82, which show optical spectra consistent with direct emission from a standard thin disk, M101 ULX-1 and M81 ULS1, which have X-ray to optical flux ratios more similar to high-mass X-ray binaries, and IC 342 X-1, in which the optical light may be dominated by the companion star. Inconsistent extinction between the optical counterpart of NGC 5204 X-1 and the nearby optical nebulae suggests that they may be unrelated.

Non-invasive markers of autonomic regulation in response to normal daily activities in health and cardiovascular disease

description: With the recognition of autonomic nervous dysregulation in the development and progression of cardiovascular diseases, such as hypertension, obesity, sleep apnoea, and heart failure, non-invasive markers of autonomic function have been widely used to predict cardiovascular risks. Short term recordings (5-10minutes) of ECG and beat-to-beat finger blood pressure are easily accessible, and carry rich information on how the sympathetic and parasympathetic nerve systems modulate the heart and blood vessels. Power spectral analysis of heart rate and blood pressure variability is a well-established tool in evaluating the sympathetic and vagal modulation. The present study investigated the autonomic responses to normal daily activities using a novel experimental protocol to mimic a common behaviour in western societies – assuming upright posture after eating. The study revealed an enhanced sympathetic activation to orthostatic stress in the postprandial state (within two hours after meal ingestion) with associated pressor and tachycardiac responses in healthy young men. In older subjects, we find a higher basal sympathetic tone, and an attenuated autonomic response to orthostatic stress and meal ingestion; interestingly, meal ingestion induced distinct sympathetic and vagal responses between older men and women, suggesting an additional factor that may increase the risk of cardiovascular diseases in postmenopausal women.Vascular dysregulation may underlie the pathogenesis of open angle glaucoma, regardless of an increase in intraocular pressure (i.e. high tension glaucoma and normal tension glaucoma). The main study, using the above experimental protocol and approaches, demonstrates for the first time a systemic autonomic dysfunction in both high tension glaucoma and normal tension glaucoma patients, and that the two forms of glaucoma manifest distinct features in autonomic responses. The study provides new evidence that open angle glaucoma may be a systemic cardiovascular autonomic disorder, and glaucomatous visual defects may be an early clinical manifestation of the continuum of multiple target organ damage later in life.
title: The Relationship Between Adult Attachment, Early Maladaptive Schemas and Alcohol Use in a Student Population
Creators: name: Rawlinson, ED

Year: 2018

description: Previous research has identified a relationship between early maladaptive schemas (EMS) and substance dependence, but there is a dearth of research investigating EMS and alcohol use in non-clinical populations, despite alcohol being the most commonly misused substance in the UK population. The aim of this study was to explore if EMS mediate the relationship between adult insecure romantic attachment (attachment anxiety and attachment avoidance) and alcohol use in a student population. A cross-sectional study of 128 student participants were recruited through the University of Liverpool intranet and by poster advertisement. Participants completed self-report measures comprising of: Alcohol Use Disorders Identification Test (AUDIT), Leeds Dependence Questionnaire (LDQ), Drinking Motive Questionnaire-Revised Short Form (DMQ-R SF), Experiences in Close Relationships –Revised (ECR-R) and Young Schema Questionnaire Short Form, Third Version (YSQ-S3). Bias-corrected bootstrapping indicated that the EMS domain ‘impaired limits’ mediated the relationship between adult insecure romantic attachment (both attachment anxiety and attachment avoidance) and alcohol use. Furthermore ‘impaired limits’ and drinking to cope with depression and anxiety were serial mediators in the relationship between attachment avoidance and alcohol use, but not for attachment anxiety and alcohol use. This research highlights the relationship between EMS and avoidant coping strategies (attachment avoidance and drinking to cope) on drinking behaviour. Key Words: Alcohol, student, schema, attachment, drinking motives.

description: With <50% 5-year survival rates, oral cancer is often diagnosed at late-stage. Detection of lesions at earlier stages results in better prognosis. Continued tobacco use after cancer treatment is a risk for recurrence. However, little is known of the process from lesion identification to diagnosis, impact of smoking behavioural changes and barriers for tobacco cessation in patients with a high-risk oral lesion (HRL) diagnosis. Two survey-type questionnaires were used to collect data on tobacco usage and patient experiences leading to HRL diagnosis. Patients attending the BC Cancer Agency diagnosed with HRLs within 12 months of interview were invited to participate in Study I. Patients who also smoked ≥100 cigarettes within 5 years of questionnaire were eligible for Study II. Among 150 Study I patients, 61% were self-identified (SIG) and 39% were professionally screened (PSG; 88% by dental professionals). PSG identified significantly more precancerous lesions compared with SIG (54% vs. 23%, P = 0.0003) and was more likely to screen ever smokers (P = 0.05). SIG showed significantly higher rates of time delay from detection to diagnosis ≥3 months, compared with PSG (58% vs. 36%, P = 0.007). Frequency of dental visits strongly correlated with identification of HRLs by healthcare professionals (P = 0.004). Common symptoms for SIG were pain (77%) and non-healing ulcers (62%), which prompted patients to seek healthcare, while 71% of PSG patients were asymptomatic. Surprisingly, almost half (47%) of patients were not aware of oral cancer. Of 58 Study II patients, main tobacco cessation barriers included stress (67%), smoking enjoyment (64%), and not being ready to quit (60%). Increased nicotine intake may be associated with increased difficulties with tobacco cessation. Knowledge of health risks from tobacco usage (71%) and tobacco cessation aids (43%) were main cessation facilitators. The HRL diagnosis was a pivotal factor for patients to stop or reduce cigarette consumption. Oral cancer screening by healthcare professionals, particularly dental professionals, can facilitate identification of earlier oral lesions at risk of cancer progression. Promotion of oral cancer awareness and tobacco cessation for patients and healthcare professionals may facilitate earlier diagnosis of oral lesions and prevent recurrent lesions.
DNA:RNA hybrid genome-wide profiling and links to genomic instability

description: DNA:RNA hybrid formation is emerging as a significant cause of genomic instability in biological systems ranging from bacteria to mammals. However, the scope of cellular pathways that prevent DNA:RNA hybrids and the genomic loci prone to hybrid formation are unclear. In Saccharomyces cerevisiae, DNA:RNA hybrids were found to be prevalent in various RNA processing, DNA repair and kinetochore mutants. In particular, mRNA cleavage and polyadenylation factors were demonstrated to maintain genome integrity by preventing transcription-dependent DNA:RNA hybrid formation. Genome-wide profiling of DNA:RNA hybrids showed that highly transcribed genes are prone to hybrid formation in the absence of hybrid-mitigating enzymes. Furthermore, the hybrid profiles highlight various genetic features prone to hybrid formation and suggest potential functions for DNA:RNA hybrids in antisense transcription regulation. Together, these findings elucidate previously unrecognized pathways that mitigate DNA:RNA hybrid formation as well as the characteristics of hybrid prone genomic regions.
Two distinct quasiparticle inelastic scattering rates in the $t-J$ model and their relevance for high-$T_c$ cuprates superconductors

description: The recent findings about two distinct quasiparticle inelastic scattering rates in angle-dependent magnetoresistance (ADMR) experiments in overdoped high-$T_c$ cuprates superconductors have motivated many discussions related to the link between superconductivity, pseudogap, and transport properties in these materials. After computing dynamical self-energy corrections in the framework of the $t-J$ model the inelastic scattering rate was introduced as usual. Two distinct scattering rates were obtained showing the main features observed in ADMR experiments. Predictions for underdoped cuprates are discussed. The implicances of these two scattering rates on the resistivity were also studied as a function of doping and temperature and confronted with experimental measurements.

description: Vitamins are biologically active compounds involved in important physiological processes in the body [1]. Preparations based on them are widely used in pharmacy. Determining the content of vitamins in various vitamin preparations such as vitamin-mineral complexes, as well as biologically active additives or food matrices is a necessary condition for monitoring the quality and safety of food products.

description: Systematic local structural studies of Ba$_{1-x}$K$_x$Fe$_2$As$_2$ system are undertaken at room temperature using atomic pair distribution function (PDF) analysis. The local structure of the Ba$_{1-x}$K$_x$Fe$_2$As$_2$ is found to be well described by the long-range structure extracted from the diffraction experiments, but with anisotropic atomic vibrations of the constituent atoms ($U_{11}$ = $U_{22} \ne U_{33}$). The crystal unit cell parameters, the FeAs$_4$ tetrahedral angle and the pnictogen height above the Fe-plane are seen to show systematic evolution with K doping, underlining the importance of the structural changes, in addition to the charge doping, in determining the properties of Ba$_{1-x}$K$_x$Fe$_2$As$_2$.

description: Any person wants to perceive the world around him and understand it. To understand means to realize the essence of an object and phenomenon, as well as to see the most necessary things in them. We can say that understanding is the most complex cognitive psychological process called thinking. Before moving on to considering the creative thinking of children of primary school age, let us define what thinking is as a psychological process in general.

description: The continued democratization of DNA sequencing has sparked a new wave of development of genome assembly and assembly validation methods. As individual research labs, rather than centralized centers, begin to sequence the majority of new genomes, it is important to establish best practices for genome assembly. However, recent evaluations such as GAGE and the Assemblathon have concluded that there is no single best approach to genome assembly. Instead, it is preferable to generate multiple assemblies and validate them to determine which is most useful for the desired analysis; this is a labor-intensive process that is often impossible or unfeasible. To encourage best practices supported by the community, we present iMetAMOS, an automated ensemble assembly pipeline; iMetAMOS encapsulates the process of running, validating, and selecting a single assembly from multiple assemblies. iMetAMOS packages several leading open-source tools into a single binary that automates parameter selection and execution of multiple assemblers, scores the resulting assemblies based on multiple validation metrics, and annotates the assemblies for genes and contaminants. We demonstrate the utility of the ensemble process on 225 previously unassembled Mycobacterium tuberculosis genomes as well as a Rhodobacter sphaeroides benchmark dataset. On these real data, iMetAMOS reliably produces validated assemblies and identifies potential contamination without user intervention. In addition, intelligent parameter selection produces assemblies of R. sphaeroides comparable to or exceeding the quality of those from the GAGE-B evaluation, affecting the relative ranking of some assemblers. Ensemble assembly with iMetAMOS provides users with multiple, validated assemblies for each genome. Although computationally limited to small or mid-sized genomes, this approach is the most effective and reproducible means for generating high-quality assemblies and enables users to select an assembly best tailored to their specific needs.

description: We derive lists of proper-motions and kinematic membership probabilities for 49 open clusters and possible open clusters in the zone of the Bordeaux PM2000 proper motion catalogue ($+11^{\circ}\leδ\le+18^{\circ}$). We test different parametrisations of the proper motion and position distribution functions and select the most successful one. In the light of those results, we analyse some objects individually. The segregation between cluster and field member stars, and the assignment of membership probabilities, is accomplished by applying a new and fully automated method based on both parametrisations of the proper motion and position distribution functions, and genetic algorithm optimization heuristics associated with a derivative-based hill climbing algorithm for the likelihood optimization. We present a catalogue comprising kinematic parameters and associated membership probability lists for 49 open clusters and possible open clusters in the Bordeaux PM2000 catalogue region. We note that this is the first determination of proper motions for five open clusters. We confirm the non-existence of two kinematic populations in the region of 15 previously suspected non-existent objects.

description: The biofilm forming bacterium Staphylococcus aureus is responsible for maladies ranging from severe skin infection to major diseases such as bacteremia, endocarditis and osteomyelitis. A flow displacement system was used to grow S. aureus biofilms in four physiologically relevant fluid shear rates (50, 100, 500 and 1000 s-1) to identify proteins that are associated with biofilm. Global protein expressions from the membrane and cytosolic fractions of S. aureus biofilm cells grown under the above shear rate conditions are reported. Sixteen proteins in the membrane-enriched fraction and eight proteins in the cytosolic fraction showed significantly altered expression (p
