description: The Johansen-Ledoit-Sornette (JLS) model of rational expectation bubbles with finite-time singular crash hazard rates has been developed to describe the dynamics of financial bubbles and crashes. It has been applied successfully to a large variety of financial bubbles in many different markets. Having been developed for more than one decade, the JLS model has been studied, analyzed, used and criticized by several researchers. Much of this discussion is helpful for advancing the research. However, several serious misconceptions seem to be present within this collective conversation both on theoretical and empirical aspects. Several of these problems appear to stem from the fast evolution of the literature on the JLS model and related works. In the hope of removing possible misunderstanding and of catalyzing useful future developments, we summarize these common questions and criticisms concerning the JLS model and offer a synthesis of the existing state-of-the-art and best-practice advices.

Design and application of combined multiphoton microscopy and optical coherence tomography system
Creators: name: Zhou, Yifeng
Publisher: name: University of British Columbia
Year: 2012

description: Optical coherence tomography (OCT) is a non-invasive optical tomographic technique based on the principle of interferometry. It can capture micrometer-resolution, three-dimensional images of tissues over millimeter field-of-view at a fast speed. Multiphoton microscopy (MPM) is an emerging imaging modality based on the excitation of nonlinear signals from fluorescent molecules and the induction of second harmonic generation (SHG). It is capable of en-face high-resolution imaging with sub-micron resolution. Although OCT and MPM are essential imaging tools for disease diagnosis, each one of them has shortages, such as the low resolution of OCT and the low depth penetration of MPM. The purpose of this study is to design a multimodal imaging system by combining MPM and OCT into a single platform so that the two modalities can complement and overcome the shortages of each other. The design consists of two parts: hardware and software. For hardware, the two modalities are integrated into a single platform, sharing the laser source, the controlling scanners and the sample arm. In addition, the OCT has a reference arm for interference and a custom-built spectrometer for signal detection, whereas the MPM uses two photomultiplier tubes (PMT) for photon detection. For software, two user interfaces are specially designed to control beam scanning and data acquisition of the MPM and OCT respectively. The performance of this mutlimodal system is demonstrated by imaging biological samples. The results indicate that our system is capable of multiscale imaging of multilayered tissues with clear structures. One of the important applications of the multimodal system is measuring the refractive index (RI) and thickness of biological tissues. This capability is demonstrated on fish cornea. The results show our system is capable of imaging as well as quantitative characterization of RI and thickness of multilayered biological tissues. This system can potentially be a powerful tool for disease detection and surgery treatment.

description: Background
                In traditional models of essential tremor, the inferior olivary nucleus was posited to play a central role as the pacemaker for the tremor. However, recent data call this disease model into question.

                Case presentation
                Our patient had progressive, long-standing, familial essential tremor. Upper limb tremor began at age 10 and worsened over time. It continued to worsen during the nine-year period he was enrolled in our brain donation program (age 85 – 94 years), during which time the tremor moved from the moderate to severe range on examination. On postmortem examination at age 94, there were degenerative changes in the cerebellar cortex, as have been described in the essential tremor literature. Additionally, there was marked degeneration of the inferior olivary nucleus, which was presumed to be of more recent onset. Such degeneration has not been previously described in essential tremor postmortems. Despite the presence of this degeneration, the patient’s tremor not only persisted but it continued to worsen during the final decade of his life.

                Conclusions
                Although the pathophysiology of essential tremor is not completely understood, evidence such as this suggests that the inferior olivary nucleus does not play a critical role in the generation of tremor in these patients.

description: We show that the Modified Newtonian Dynamics (MOND) regime can be fully recovered as the weak-field limit of a particular theory of gravity formulated in the metric approach. This is possible when Milgrom's acceleration constant is taken as a fundamental quantity which couples to the theory in a very consistent manner. As a consequence, the scale invariance of the gravitational interaction is naturally broken. In this sense, Newtonian gravity is the weak-field limit of general relativity and MOND is the weak-field limit of that particular extended theory of gravity. We also prove that a Noether's symmetry approach to the problem yields a conserved quantity coherent with this relativistic MONDian extension.

NP in hadronic tree-level affects determination of gamma

description: We show how current state of the art experimental and theoretical determinations allow for sizable New physics (NP) effects in the non-leptonic Wilson coefficients C_1 and C_2. We argue that power corrections in the QCD factorization formalism play an important role in reducing the regions for these potential NP contributions. We evaluate the impact of these NP corrections in the determination of the angle CKM $\gamma$ as well as on the B mixing observable $\Delta \Gamma_d$.
Middle Anglo-Saxon Continental Wares in Norfolk

description: Medieval Ceramics: Journal of the Medieval Ceramics Research Group, 32, 1-9
description: During the Middle Anglo-Saxon period, the distribution of imported ceramics in Norfolk provides an excellent opportunity to identify settlements and to reconstruct regional economies. An analysis of their distribution suggests that the contrasting distributions might indicate contrasting trading networks comprising unregulated mercantile exchange within the coastal zone and ecclesiastical or secular controlled exchange and consumption further inland. In addition, certain wares may have been considered only a minor valuable within the emergent centre of Norwich, prior to re� distribution inland where they attained a higher status. This potential new model - of diverse control over ceramic distribution- stands in opposition to the more rigid anthropologically influenced models of exclusive royal control over exchange pioneered by Hodges (1982) and can serve as a hypothesis for future testing.

description: We present a simple physically motivated picture for the mildly non-linear regime of structure formation, which captures the effects of the bulk flows. We apply this picture to develop a method to significantly reduce the sample variance in cosmological N-body simulations at the scales relevant to the Baryon Acoustic Oscillations (BAO). The results presented in this paper will allow for a speed-up of an order of magnitude (or more) in the scanning of the cosmological parameter space using N-body simulations for studies which require a good handle of the mildly non-linear regime, such as those targeting the BAO. Using this physical picture we develop a simple formula, which allows for the rapid calculation of the mildly non-linear matter power spectrum to percent level accuracy, and for robust estimation of the BAO scale.

description: As in much of the world, mental health law in Israel has evolved over the past half-century toward greater protection of patients’ liberty and an increased emphasis on due process. Part of that process in Israel involved taking decisions about prolonged involuntary hospitalization out of the hands of treating psychiatrists and turning them over to independent review panels. Argo and colleagues examined outcomes of discharge decisions made by these panels compared with treating psychiatrists. In this brief commentary, we describe related trends in mental health law in other countries, especially the U.S., consider countervailing perspectives on the role of review panels, and suggest how the Argo et al. study might be followed up with additional research.
Carcinoma of the Gallbladder: Current State and Future Directions in Diagnosis and Treatment

description: Gallbladder cancer (GBC) was first reported in 1777 (Lazcano-Ponce et al., 2001). Today it is most often found in two situations, which are late stage with constitutional symptoms and positive imaging findings, and early stage, incidentally diagnosed after cholecystectomy for other disease. The incidence of GBC has declined over the last few decades and the survival time is also better than in the past. With the improvement of treatment and imaging techniques, the future promises more late stage cases will survive longer and more early stage cases will be discovered. We are optimistic this will lead to increased survival times on the whole and eliminate the current fear of GBC as a highly mortal cancer (Gourgiotis et al., 2008).

Starting from static baryons in the helicity eigenstates, we generalize their wavefunctions to the non-static and relativistic regime. A new representation for gamma matrices in the SU(2) collective space is constructed and the corresponding Dirac equation is obtained. Furthermore, we extend the analysis of Adkins et al. concerning vector current vacuum expectation values for baryon states to arbitrary momenta and calculate baryon elastic form factors in a general framework exhibiting vector meson dominance.

description: Medieval Ceramics: Journal of the Medieval Ceramics Research Group, 32, 10-27
description: Pottery with a surface decoration employing different colours of slip to imitate marble and other semi-precious stones was made in Tuscany from about 1570 to 1650. Marbleized pottery is in many ways a typical product of the Counterreformation It was certainly made in Pisa and recent discoveries have revealed that it was also produced in several other towns along the Arno river between Florence and the Tyrrhenian coast. This paper proposes to explore three main aspects of Tuscan marbleized pottery: why it was made, where it was made and how it was made.
Polymer–surfactant interaction for controlling the rheological properties of aqueous surfactant solutions

description: Controlling viscosity of aqueous surfactant solutions is very important for practical formulations. This can be done by having polymers interact with surfactants, thereby forming interconnected physical networks, where main ways of interaction are electrostatic and hydrophobic forces. Polymer–surfactant interactions are long established for viscosity control, but there are many ongoing activities. They are driven by wanting more biocompatible systems, which depend intricately on the choice of surfactant and polymer, and general predictions are not simple for such systems. Surfactants form spherical or wormlike micelles or vesicles. By choice of (co)polymers one can construct systems responsive to external parameters, like temperature or pH, for having tailored rheological properties. Here we describe recent developments with a focus on systems of low concentration, being interesting for applications. In summary, rheological control of polymer–surfactant systems is a versatile topic and a field of colloid science with high relevance for practical formulations.
title: DEPRECATED: GATS Impacts on Entry Modes and Defensive Marketing Strategies in the Egyptian Banking Sector
Creators: name: Lotayif, Mansour Salman Mohamad Abdel-Maguid
Publisher: name: University of Plymouth
Year: 2004

description: This research examines the effects of GATS agreements, both on entry modes and defensive marketing strategies in the Egyptian banking sector. The research population is the Egyptian banking sector, employing a total of 83179, from which a representative sample (equal to 800 responses) was selected. As the research aims are diversified, this sample was divided into two main groups i.e. local banks and foreign branches, investigated using different questionnaires. The latter population includes all the foreign branches working in the Egyptian market; the former includes all banks working in Egypt regardless of their ownership status. Four objectives have been pursued in this research: - (1) Exploring GATS impacts on the Egyptian banking sector as well as identifying variables that affect their perception; (2) Identifying the appropriate defensive marketing strategies for each entry mode and evaluating the marketing practices of the Egyptian banking sector; (3) Identifying pattems of relationships between defensive marketing strategies and four sets of variables (demographics, objectives, rivals, and rivals' competitive advantages); and (4) Determining the factors that affect the selection of each entry mode. Regarding the first research objective, the findings reveal that GATS agreements have positive impacts on the Egyptian banking sector, with significant relationships observed between the perception of GATS impacts and the respondents backgrounds. Secondly, an "Entry Modes- Defensive Marketing Strategies Model" was designed, recommending specific defensive marketing strategies for each bundle of entry modes. Thirdly, strong and significant relationships appear, between selected defensive marketing strategies and four sets of variables i.e. demographics, bank's objectives, perceived competitors, and competitors' competitive advantages. Finally, the selection of entry modes is affected by both bank and target market characteristics. The latter include political stability as well as instability, language differences, religious similarities, values differences, severe competition, and moderate levels of competition; the former include greater as well as less financial resources, and less international experience. The applicability and suitability of these findings for other similar Afiican and Middle East countries are identified.

description: Background
                Over 900 travel-associated Zika virus cases have been identified in New York City (NYC), New York. A survey was administered in NYC adapted from the Knowledge, Attitudes, and Practices (KAP) survey on Zika virus developed by the World Health Organization (WHO).

                Methods
                A standardized, self-administered, anonymous questionnaire was administered to a convenience sample in Manhattan and the Bronx from June 30th, 2016 to October 21st, 2016. Responses were grouped into six domains based on the content and structure of the questions and were summarized using descriptive statistics or converted into a continuous knowledge score and assessed for associations with pregnancy status and travel history using linear regression.

                Results
                There were 224 respondents with a mean age of 33 (SD ± 11.6) with 77% (170/224) female and 24% (51/224) pregnant. The majority (98% (213/217)) were unable to identify all of the symptoms associated with acute Zika virus infection and all modes of transmission (97% (213/219)). Most participants (85% (187/219)) identified mosquitoes as a mode of transmission. 95% (116/122) reported an association between Zika virus and microcephaly. The most concerning aspect of Zika virus in 46% (91/200) was the risk of disabilities to babies, and risk of sexual transmission (25% (49/200)). When asked what precautions pregnant persons should to reduce the risk of transmission when traveling to a Zika endemic region, only 27% (50/185) identified using condoms during intercourse or refraining from intercourse while pregnant. Knowledge of Zika transmission is significantly positively associated with pregnancy status, but not with travel history.

                Conclusion
                Our results indicate an overall poor understanding of Zika virus symptoms and possible complications, transmission modes, and current recommended prevention guidelines. Pregnancy is positively associated with Knowledge of Zika Transmission, but not other knowledge scores. Reported travel history to Zika endemic regions is not significantly associated with Zika knowledge. There is a need for implementing future public health interventions that particularly focus on protection against Zika transmission, that Zika is sexually transmitted, and risks that the Guillain-Barré Syndrome poses a risk to adults.

description: This study aims to develop an implicit measure of alexithymia using reaction times to emotional stimuli. Participants will be presented with facial expression images representing neutral, positive, and negative emotions. Participants will be asked to press a button as soon as they know how the image makes them feel. They do not need to indicate any emotion, simply press a button when they know. We will record the reaction time (RT) it takes for participants to report experiencing an emotional response to each image. To assess the validity of this implicit measure, participants’ reaction times will be correlated with their scores on two established self-report measures: the 20-item Toronto Alexithymia Scale (TAS-20) and the Depression, Anxiety, and Stress Scales (DASS-21). Methodology: A cross-sectional design will be employed with an expected sample size of 200 adult participants (aged 18+), recruited via Prolific. All participants will receive monetary compensation for their participation. There will be appr 100 trials, a third of them will be neutral expressions, a third of them will be positive expressions and a third will be negative expressions. We will first conduct Pearson correlations to explore associations between TAS-20 scores, DASS-21 depression subscale scores, and reaction times for neutral, positive, and negative stimuli. Subsequently, three linear regression analyses will be performed—one for each stimulus type—with TAS-20 and depression scores as predictors and reaction time as the dependent variable. This will help determine whether reaction times are more strongly associated with alexithymia or depressive symptoms and whether this relationship might be stronger for a particular type of emotional expression.

description: This Guidebook is designed to serve as a practical reference source to help open source software programs serving cultural and scientific heritage organizations plan for long-term sustainability, ensuring that commitment and resources will be available at levels sufficient for the software to remain viable and effective as long as it is needed.

One of the most significant themes of this Guidebook is that sustainability is not a linear process, with set beginning and end points. Program sustainability shifts and evolves over time across a number of phases and facets. The phases speak to where a program is in its lifecycle: getting started, growing, or stable but not static. The facets describe the different components of sustainability, each of which is critical to overall program health, but may have different timelines, goals, and resource needs. The facets deemed
most critical by the Guidebook’s authors and contributors are:  Governance, Technology, Resources (Financial and Human), and Community Engagement.

Sections of the Guidebook will: define the phases and facets of sustainability; identify goals, characteristics, and common roadblocks for each phase in each facet; provide guidance for moving an OSS program to the next phase in a given facet, with the understanding that the same program may be in different phases along different facets of sustainability; and highlight case studies and additional resources to help a program’s research and decision-making process.

The Guidebook is intended for a broad audience. While certain paths may be of more interest than others, we would recommend reading through each of the facets before returning to the one that aligns most closely with a specific role, e.g., governance for a program manager, technology for a technical lead, engagement for a community manager, or resources for an administrator. The worksheet in Appendix A can help identify the specific phase a program is in along each facet.

The open source landscape is wide and varied. Bringing open source programs serving cultural and scientific heritage together under one shared umbrella can provide us all with the power to better advocate for our needs, develop shared sustainability strategies, and provide our communities with the information needed to assess and contribute to the sustainability of the programs they depend on.

description: Cellular imaging is a rapidly growing field as novel tracers and imaging techniques are developed. Magnetic particle imaging (MPI) detects superparamagnetic iron oxide (SPIO) particles, which can be used to label cells., The type of SPIO has a critical role in determining MPI sensitivity and resolution. For cell tracking applications, the ideal SPIO should label cells efficiently and retain its sensitivity after cellular uptake. VivoTraxTM, a commercially available and commonly used SPIO for MPI, was recently re-released as VivoTrax+ with an improved size distribution enriched for larger particles. In this study, VivoTrax+ is shown to enhance cellular labeling and improve in vitro/in vivo sensitivity. Importantly, the sensitivity of both SPIO significantly decreased after cellular internalization. The results from this study emphasize the importance of translating SPIO performance in vivo to maintain its utility for cell tracking applications. Int. J. Mag. Part.

description: Using high sensitivity magneto-optical imaging we find evidence for a jump in local vortex density associated with a vortex liquid to solid phase transition just above the lower critical field in a single crystal of Bi2Sr2CaCu2O8. We find the regions of the sample where the jump in vortex density occurs are associated with low screening currents. In the field - temperature vortex phase diagram we identify phase boundaries demarcating a dilute vortex liquid phase and the vortex solid phase. The phase diagram also identifies a coexistence regime of the dilute vortex liquid and solid phases and shows the effect of pinning on the vortex liquid to solid phase transition line. We find the phase boundary lines can be fitted to the theoretically predicted expression for the low-field portion of the phase boundary delineating a dilute vortex solid from a vortex liquid phase. We show that the same theoretical fit can be used to describe the pinning dependence of the low-field phase boundary lines provided a dependence of the Lindemann number on pinning strength is considered.

The Medieval and Later Pottery From Niddrie Near Edinburgh

description: Medieval Ceramics: Journal of the Medieval Ceramics Research Group, 32, 54-71
description: A combination of principal components and discriminant analysis was used to interpret the ICP analyses on Niddrie pottery, following the approach used for Scottish redware (Haggerty et al 2011) and Scottish white gritty ware (Jones et al 2002/3). The patterns in the chemical analysis data of the Niddrie pottery were used to select suitable material from the respective ICP databases on Scottish pottery to compare against them. The ICP analysis of pottery from Niddrie Burn has shown definite patterns allowing probable identifications of the general location of the sources of the pottery. Of the SPMOW and SPMRW sherds, many showed an Upper Forth composition, specifically linking them to kiln material from Stenhouse and Throsk. One sherd (GH06) seemed to definitely have the Throsk element pattern, while another (GH09) fell just outside the Stenhouse/Throsk group but appears to be an Upper Forth sherd. In contrast three appeared to be from East of the city: two SPMOW sherds (GH04 and GH05) and one SPMRW (GH15) seemed associated with the West Pans kilns. Sherd (GH08) was unusual with only half the iron content and a higher alumina compared to the rest of the redware sherds and did not conform to the composition of any of the pottery from the kiln sites tested, so at present its origin is unknown. In contrast, all the SWGW appeared to originate in East Lothian, though without an exact match with the analysed sherds from sites in the region. There was some consistency in the composition sub-groups found among the Niddrie SWGW, and although the nearest composition was to pottery from Archerfield, there was some indication that a Colstoun sub-group had been made of similar clay to most of the Niddrie SWGW. Very similar graphs were obtained for statistical tests on the same groups of ICP analyses of Scottish pottery which had been published in earlier investigations.
Progressive expression of anger : communicative anger in contexts of counterpublics
Creators: name: Kojic, Mladen
Publisher: name: University of British Columbia
Year: 2012

description: This paper investigates Audre Lord’s intuitive claim that anger is a progressive emotion, developing the theoretical context that underwrites this critical insight. Drawing on Martha Nussbaum’s work on emotions, the paper argues that anger is a cognitive and evaluative emotion, containing assertoric propositions which are amenable to discourse. Beginning form the cognitivist view of emotions, the normative grammar of a progressive expression of anger is brought into the preview of Jürgen Habermas’ discourse ethics. Despite the strategic nature of anger as an assertion of particularistic grievance, the work of Arash Abizadeh expands communicative action to encompass speech acts with perlocutionary aims, repositioning the propositional content of anger as the motivationally efficacious component of discursive engagement. This however is only achieved within the bounded space of institutions nurturing of civic engagement through the medium of talk. The later part of the paper develops the dialectic between the institutional space of the public sphere and that of its counterpublics, where diffuse experiences of anger are conditioned and refined by the plurality of perspectives comprising counterpublics for the purpose of therapeutic grievance airing, identity confirming discourse, and the dialogical development of political interests.

Motivated by this, aspects of hysteresis during unzipping of DNA under a periodic drive in non-equilibrium conditions are studied. A steady state phase diagram of a driven DNA is proposed which is experimentally verifiable. As a two state system, we also compare the results of DNA with that of an Ising magnet under an asymmetrical variation of magnetic field.

description: Composite Higgs models are only now starting to be probed at the Large Hadron Collider by Higgs searches. We point out that new resonances, abundant in these models, can mediate new production mechanisms for the composite Higgs. The new channels involve the exchange of a massive color octet and single production of new fermion resonances with subsequent decays into the Higgs and a Standard Model quark. The sizable cross section and very distinctive kinematics allow for a very clean extraction of the signal over the background with high statistical significance.

Following their Trade Without Interruption: Evidence of the Flemish Potters and Early Tin-Glazed Ware Production in Norwich
Creators: name: Goffin, Richenda
Publisher: name: Archaeology Data Service
Year: 2023

description: Medieval Ceramics: Journal of the Medieval Ceramics Research Group, 32, 72-86
description: This paper presents some preliminary findings on pottery and kiln related material found in the infill of a well excavated close to the location of the original tin-glazed earthenware production centre set up in Norwich by Jasper Andries and Jacob Jansen in AD 1567. The ceramic material is discussed in relationship to other early groups of tin-glazed wares both in the Netherlands and in London. The possibility that the Dutch potters were also producing redwares is also investigated.

description: We treat three types of measures of the quantum walk (QW) with the spatial perturbation at the origin, which was introduced by [1]: time averaged limit measure, weak limit measure, and stationary measure. From the first two measures, we see a coexistence of the ballistic and localized behaviors in the walk as a sequential result following [1,2]. We propose a universality class of QWs with respect to weak limit measure. It is shown that typical spatial homogeneous QWs with ballistic spreading belong to the universality class. We find that the walk treated here with one defect also belongs to the class. We mainly consider the walk starting from the origin. However when we remove this restriction, we obtain a stationary measure of the walk. As a consequence, by choosing parameters in the stationary measure, we get the uniform measure as a stationary measure of the Hadamard walk and a time averaged limit measure of the walk with one defect respectively.

description: Background
                The Doris Duke Charitable Foundation’s African Health Initiative supported the implementation of Population Health Implementation and Training (PHIT) Partnership health system strengthening interventions in designated areas of five countries: Ghana, Mozambique, Rwanda, Tanzania, and Zambia. All PHIT programs included health system strengthening interventions with child health outcomes from the outset, but all increasingly recognized the need to increase focus to improve health and outcomes in the first month of life. This paper uses a case study approach to describe interventions implemented in newborn health, compare approaches, and identify lessons learned across the programs’ collective implementation experience.

                Methods
                Case studies were built using quantitative and qualitative methods, applying the World Health Organization Health Systems Strengthening Framework, and maternal, newborn and child health continuum of care framework. We identified the following five primary themes in health systems strengthening intervention strategies used to target improvement in newborn health, which were incorporated by all PHIT projects with varying results: health service delivery at the community level (Tanzania), combining community and health facility level interventions (Zambia), participatory information feedback and clinical training (Ghana), performance review and enhancement (Mozambique), and integrated clinical and system-level improvement (Rwanda), and used individual case studies to illustrate each of these themes.

                Results
                Tanzania and Zambia included significant community-based components, including mobilization and sensitization for increased uptake of essential services, while Ghana, Mozambique, and Rwanda focused more efforts on improving the quality of services delivered once a patient enters a health facility. All countries included aspects that improved communication across levels of the health system, whether through district-wide data sharing and peer learning networks in Mozambique and Rwanda, or improved referral processes and systems in Tanzania, Zambia, and Ghana.

                Conclusion
                Key lessons learned include the importance of focusing intervention components on addressing drivers of neonatal mortality across the maternal and newborn care continuum at all levels of the health system, matching efforts to improve service utilization with provision of high quality facility-based services, and the critical role of leadership to catalyze improvements in newborn health.
Medial and Lateral Entorhinal Cortex Differentially Excite Deep versus Superficial CA1 Pyramidal Neurons

description: Although hippocampal CA1 pyramidal neurons (PNs) were thought to comprise a uniform population, recent evidence supports two distinct sublayers along the radial axis, with deep neurons more likely to form place cells than superficial neurons. CA1 PNs also differ along the transverse axis with regard to direct inputs from entorhinal cortex (EC), with medial EC (MEC) providing spatial information to PNs toward CA2 (proximal CA1) and lateral EC (LEC) providing non-spatial information to PNs toward subiculum (distal CA1). We demonstrate that the two inputs differentially activate the radial sublayers and that this difference reverses along the transverse axis, with MEC preferentially targeting deep PNs in proximal CA1 and LEC preferentially exciting superficial PNs in distal CA1. This differential excitation reflects differences in dendritic spine numbers. Our results reveal a heterogeneity in EC-CA1 connectivity that may help explain differential roles of CA1 PNs in spatial and non-spatial learning and memory.
The Order on Projections in C*-Algebras of Real Rank Zero

description: We prove a number of fundamental facts about the canonical order on projections in C*-algebras of real rank zero. Specifically, we show that this order is separative and that arbitrary countable collections have equivalent (in terms of their lower bounds) decreasing sequences. Under the further assumption that the order is countably downwards closed, we show how to characterize greatest lower bounds of finite collections of projections, and their existence, using the norm and spectrum of simple product expressions of the projections in question. We also characterize the points at which the canonical homomorphism to the Calkin algebra preserves least upper bounds of countable collections of projections, namely that this occurs precisely when the span of the corresponding subspaces is closed.
Generation of mesoscopic entangled states in a cavity coupled to an atomic ensemble

description: We propose a novel scheme for the efficient production of "NOON states" based on the resonant interaction of a pair of quantized cavity modes with an ensemble of atoms. We show that in the strong-coupling regime the adiabatic evolution of the system tends to a limiting state that describes mesoscopic entanglement between photons and atoms which can easily be converted to a purely photonic or atomic NOON state. We also demonstrate the remarkable property that the efficiency of this scheme increases exponentially with the cavity cooperativity factor, which gives efficient access to high number NOON states. The experimental feasibility of the scheme is discussed and its efficiency is demonstrated numerically.

description: In recent years our understanding of the native medieval pottery industries of Scotland has under� gone a trans-formation due to the application of finance, science and common sense. However there is still a large part of the country where this is not the case and the hapless pottery specialist is presented with assemblages that are dominated by local products that do not appear to change to any great extent over at least a thousand years. This paper will consider the best way forward for understanding such a widespread pottery tradition using currently available scientific techniques for sourcing and dating. Finally discussion will turn to the knotty problem of how to attract the level of funding that will be required to adequately tackle a problem of such scale.

description: Aims. We intend to compile a new galaxy group and cluster sample of the latest available SDSS data, adding several parameter for the purpose of studying the supercluster network, galaxy and group evolution, and their connection to the surrounding environment. Methods. We used a modified friends-of-friends (FoF) method with a variable linking length in the transverse and radial directions to eliminate selection effects and to find reliably as many groups as possible. Using the galaxies as a basis, we calculated the luminosity density field. Results. We create a new catalogue of groups and clusters for the SDSS data release 8 sample. We find and add environmental parameters to our catalogue, together with other galaxy parameters (e.g., morphology), missing from our previous catalogues. We take into account various selection effects caused by a magnitude limited galaxy sample. Our final sample contains 576493 galaxies and 77858 groups. The group catalogue is available at http://www.aai.ee/~elmo/dr8groups/ and from the Strasbourg Astronomical Data Center (CDS).
