description: In magnetotransport measurements on arrays of cross-shaped antidots, we observe pronounced features in both the longitudinal and transverse magnetoresistivities $\rho$$_{xx}$ and $\rho$$_{xy}$, which cannot be understood within the simple framework of commensurability between cyclotron radius and superlattice period. These resonances can be regarded as magnetotransport fingerprints of the complex unit cell. With the help of detailed numerical calculations using classical linear response theory we can ascribe additional maxima in $\rho$$_{xx}$ to closed orbits in the dotlike potential between four antidots. A pronounced minimum in $\rho$$_{xy}$ demonstrates the significance of open trajectories.

Subjects: subject: 530 Physik

description: We investigate the low-field magnetotransport properties of a two-dimensional electron gas with a strong magnetic modulation in two directions by means of the classical Kubo theory. The magnetoresistivity shows distinct maxima, which do not correspond to pinned orbits commensurate with the superlattice constant in contrast to electrostatic antidot systems. The features in the magnetoresistivity can be ascribed to the interplay between the chaotic dynamics of the system and regular motion on open trajectories through the superlattice.
Screw Dewatering of Faecal Sludge

description: A significant inhibitor for faecal sludge management are the high emptying and transport cost
 attributed to rheologically difficult sludge types and volumes consisting of over 95% water
 (Basamykina et al., 2020; Gold et al., 2016). Onsite solid/liquid separation, which removes water
 before transport, could be the critical step in making faecal sludge management economically
 feasible. Thickening and dewatering processes represent the initial water removal stages to minimise
 sludge volume. They play a key role in preparing faecal solids for downstream processes which
 facilitate safe environmental disposal through drying or pasteurisation (Brockmann, 1973; Naidoo et
 al., 2020; Septien et al., 2018), or sustainable sanitation opportunities such as the provision of energy
 or fertiliser product from an organic and nutrient rich solid phase (Eshetu Moges et al., 2018; Forbis-
 Stokes et al., 2016; Harder et al., 2019; Onabanjo et al., 2016). As such, localised solid/liquid
 separation could enable a community accepted shift towards sustainable faecal sludge management
 (Mikhael et al., 2014). However, there is limited understanding of the material properties of faecal
 solids which ultimately govern how to design and manage solid/liquid separation processes. This
 project contributes to the transformative technologies portfolio by providing the required fundamental
 scientific knowledge of fresh faeces rheology and dewaterability to design and implement effective
 solids/liquid separation for non-sewered sanitation. This was achieved in collaboration with Shane Usher from Melbourne University, who leads research on the rheology and dewaterability of particulate matrices. We have adapted these methods for the characterisation of faeces.

description: We investigated antidot lattices with Andreev reflecting boundaries both in experiment and theory. The samples consist of arrays of niobium-filled antidots in an InAs-based heterostructure. The quality of the Nb–InAs contact could be controlled by an in situ Ar+ sputter cleaning step. In samples with a high transparency contact, we find a strong reduction of the resistance around B=0 and a suppression of the commensurability peaks. These observations can be explained in a classical Kubo approach by including Andreev reflection and assuming a magnetic-field-dependent Andreev reflection probability.

description: Using photometric data of infrared surveys, young stellar object (YSO) status is verified for 141 objects selected in our previous papers in the Cassiopeia and Camelopardalis segment of the Milky Way bounded by Galactic coordinates (l, b) = (132--158 deg, p/m 12 deg). The area includes the known star-forming regions in the emission nebulae W3, W4 and W5 and the massive YSO AFGL 490. Spectral energy distribution (SED) curves between 700 nm and 160 microns, constructed from the GSC2, 2MASS, IRAS, MSX, Spitzer and AKARI data, are used to estimate the evolutionary stages of these stars. We confirm the YSO status for most of the objects. If all of the investigated objects were YSOs, 45 % of them should belong to Class I, 41 % to class II and 14 % to Class III. However, SEDs of some of these objects can be affected by nearby extended infrared sources, like compact H II regions, infrared clusters or dusty galaxies.

The cell biology of cellulose deposition in secondary cell walls of protoxylem tracheary elements in Arabidopsis thaliana
Creators: name: Watanabe, Yoichiro
Publisher: name: University of British Columbia
Year: 2018

description: Cellulose is the most abundant polymer in nature and is a major component of both primary and secondary cell walls in plants. The cellulose produced in these different walls are synthesized by completely independent sets of non-redundant CELLULOSE SYNTHASE (CESA) enzymes. In the last decade, live cell imaging techniques have answered a number of fundamental questions regarding CESA dynamics and organization in the primary cell wall. However, attempts to repeat these experiments in cells producing secondary cell walls has been met with limited success due to the fact that cells forming secondary walls are deep inside plant organs. The development of an inducible system driving the ectopic expression of the master regulator for protoxylem tracheary element development, VASCULAR RELATED NAC-DOMAIN7 (VND7), has generated a valuable biological tool to track secondary cell wall synthesis via live-cell imaging. With these tools, I was able to directly visualize secondary cell wall-specific CESA complexes moving around the plasma membrane, and to quantify that they move at a significantly faster rate than primary cell wall-specific complexes. Additionally, bundling of the underlying cortical microtubules causes the densities of the CESA complexes to be much higher during secondary wall synthesis than during primary wall synthesis, giving a possible explanation for the rapid and abundant development of these walls. Analysis of the transition from primary to secondary cell wall production revealed that primary wall-specific CESAs are selectively targeted into distinct pre-vacuolar compartments for degradation to the lytic vacuole, while secondary cell wall-specific CESAs accumulate. Finally, cesa mutants were investigated to explore the effects of the loss of each of the three CESAs involved in secondary cell wall cellulose synthesis on both the wall patterning and localization of their interacting partners. While the loss of a CESA causes significant defects in secondary cell wall cellulose patterning, the loss of CESA7 specifically resulted in the complete loss in patterning, indicating a possible role for CESA7 in anchoring the CESA complexes to the underlying cortical microtubules. Taken together, these results refine our model of how plant cells coordinate their cellulose synthesis machinery during secondary cell wall production.
Likelihood inference for particle location in fluorescence microscopy

description: We introduce a procedure to automatically count and locate the fluorescent particles in a microscopy image. Our procedure employs an approximate likelihood estimator derived from a Poisson random field model for photon emission. Estimates of standard errors are generated for each image along with the parameter estimates, and the number of particles in the image is determined using an information criterion and likelihood ratio tests. Realistic simulations show that our procedure is robust and that it leads to accurate estimates, both of parameters and of standard errors. This approach improves on previous ad hoc least squares procedures by giving a more explicit stochastic model for certain fluorescence images and by employing a consistent framework for analysis.

description: We present calculations of the magnetoconductivity in a two-dimensional electron system including the Rashba spin-orbit interaction. Essential for these calculations is an extension of the self-consistent Born approximation which takes into account the electron spin degree of freedom. The calculated magnetoconductivity exhibits, besides the beating in the Shubnikov-de Haas oscillations, a modulation related to the spin-orbit induced crossings of Landau levels, as a consequence of spin-conserving scattering between spin-orbit coupled states.

description: An Andreev billiard was realised in an array of niobium filled antidots in a high-mobility InAs/AlGaSb heterostructure. Below the critical temperature T_C of the Nb dots we observe a strong reduction of the resistance around B=0 and a suppression of the commensurability peaks which are usually found in antidot lattices. Both effects can be explained in a classical Kubo approach by considering the trajectories of charge carriers in the semiconductor, when Andreev reflection at the semiconductor-superconductor interface is included. For perfect Andreev reflection, we expect a complete suppression of the commensurability features, even though motion at finite B is chaotic.

description: In the context of a Two-Higgs-Doublet Model in which Minimal Flavour Violation (MFV) is imposed, one can allow the presence of flavour-blind CP-violating phases without obtaining electric dipole moments that overcome the experimental bounds. This choice permits to accommodate the hinted large phase in the $B_s$ mixing and, at the same time, to soften the observed anomaly in the relation between $ε_K$ and $S_{ψK_S}$.

description: This study aims to predict the environmental, organizational, and managerial factors that determine the adoption of cloud computing in U.S. healthcare delivery systems. The premise of the analysis is that several internal and external factors determine a health provider’s transition to cloud computing. The U.S. government has funded healthcare providers through HITECH (Health Information Technology for Economic and Clinical Health) to implement electronic health records (EHR) which is considered as an important first step in transitioning to cloud computing. This study investigated whether there is a significant difference between hospitals and providers that received HITECH funding to enhance their EHR infrastructure and those that did not in terms of their external environmental complexities, internal organizational structure, and quality of healthcare services they provide. A stratified random sample was applied to select a cohort of 3,385 hospitals from the American Hospital Association (AHA) 2022 roster for the period 2018- 2021 to test the study hypothesis. The sampled hospitals were linked with claim, administrative, cost, and ICD-10 clinical data files to capture variables of interest repeatedly over the study period. The analysis modeled for selected external (location, market concentration as measured by Herfindahl Index), internal (number and composition of staff – physicians, nurses, technicians, etc.) demographic, clinical and financial factors. Quantitative methods such as generalized estimating equations (GEE), logistic regression, and generalized linear mixed model (GLMM) were applied within the framework of unified technology acceptance theory (UTAT), accounting for both discrete and continuous response variables while modeling for possible between-subject heterogeneity and within-subject correlations. The analysis is based on publicly available data sources that are systematically linked to address the research questions. The portion of the HITECH funding that is applied for cloud computing is calculated from the hospital’s EHR funding. This is one of the very few longitudinal time series studies of cloud computing in healthcare since almost all previous studies on American hospitals are cross-sectional. The findings of this study show statistically significant differences between hospitals that received government funding in terms of internal organizational structure, environmental complexity, and quality of healthcare provided. The analysis identified management and quality metrics that help to gauge continuously changing organizational needs and identify emerging trends. This study proposes specific topics that future researchers can consider promoting a successful implementation of cloud computing.

description: The use of Sonic Crystals as environmental noise barriers has certain advantages from the acoustical and the constructive point of view with regard to conventional ones. One aspect do not studied yet is the acoustic interaction between the Sonic Crystals and the ground due to, up to now, this latter is not included in the analytical models used to characterize these Sonic Crystals. We present here an analytical model, based on multiple scattering theory, to study this interaction considering the ground as a finite impedance surface. Using this model we have obtained interesting conclusions that allow to design more effectively noise screens based on Sonic Crystals. The obtained results have been compared with experimental and numerical, finding a good agreement between them.

description: Quantum dots (QDs) realized by etching or gate structures in a two-dimensional electron system may, under realistic conditions, contain an impurity atom which causes deviations of the electron structure from the ideal case. We have performed ground-state calculations for circular disk-like QDs with a parabolic confinement potential and a repulsive off-center impurity. Besides the distance of the impurity from the dot center we can vary its strength using a Coulomb potential for its shape. The essential effect of the off-center impurity is the breaking of the axial symmetry with the consequence of removing degeneracies in the single-particle spectrum which is related to shell and spin phenomena. We quantify these effects in the ground-state energy and the spin densities by applying spin-density functional theory (SDFT) in the local spin density approximation (LSDA).

description: In the German-speaking world, we have books on Scanderbeg starting from the XVI century. The primary source of the German historiography on Scanderbeg was Marin Barleti’s work “Historia de vita et gesti Scanderbegii” which was translated by, in 1533. During the XVI century, we have some works by German humanists, such as Cuspinianus “On the Origin of the Turks,” Levenklaus's “The Annales of the Ottoman Sultans” and Camerarius's “Two Detailed Commentaries on the Turks’ Affairs” in 1598, where the author also refers to the life of Scanderbeg. In the XVII century, we can mention here the work by the humanist Johannes Lassenius “The Turks’ might mocked by Deity”, based upon Barleti’s book. In XVIII we do not have original works, but only reproductions of the history written by Barleti and encyclopedic articles always referring to this book. In the XIX century, there were some monographs, the first being the book by Wilhelm Becker, ﬁrstly published in the Berlin magazine “Der Freimütige” under the title “Gjergj Scanderbeg and Murad”. Becker published this book in 1821 under a new title “Gjergj Scanderbeg and Murad, or Gjergj Scanderbeg, the fortunate forerunner of Alia Pasha of Joannina”. In 1827, an anonymous and philhellenist author with the initials G. K. published the study “Gjergj Kastrioti. A sketchy biography of the past times, compared to ours”. The third monograph was by Julius Piskos, “Scanderbeg ”, which came out in 1894. Besides these monographs we have numerous other works where we can ﬁnd indirect information on Scanderbeg, such as “The History of the Ottoman Empire”, by Cuspinianus'sin 1827, “The History of the Ottoman Empire in Europe” by Zinkeisen and published in 1840, “The Albanian element in Greece” of 1866 written by Fallmereyer. Regarding the German historiography of the XX century and that of the XXI century, we have “Mehmet the Conqueror”, by Franz Babinger, who is critical of Marin Barleti’s work, and “Scanderbeg” by Oliver Jens Schmitt, which is the most detailed study on this ﬁgure.
Improving cervical neoplasia diagnosis via novel in vivo imaging technologies and deep learning algorithms
Creators: name: Sheikhzadeh, Fahime
Publisher: name: University of British Columbia
Year: 2018

description: Two directions are explored for improving the current cervical cancer diagnosis procedure. The first investigates the future deployment of in vivo confocal imaging in the clinic, for detecting precancerous tissues, and the second proposes an algorithm for automatic interpretation of histology images (acquired by light microscopy). We acquired i) confocal microscopy images of cervical biopsies taken from 50 patients, at different tissue depths and ii) histology images of different sections cut from each biopsy. From the confocal images, we identified four features that carry enough information relevant to cell morphology and tissue architecture. We demonstrated that the relevant information in these features is comparable to that extracted from the same features in histology images. This implies that we can obtain the relevant information from confocal imaging, without having to cut a biopsy from the patient’s cervix. We then studied the confocal images and determined the grade lesion of every biopsy and found that confocal imaging resulted in less false positives than the diagnosis given by the gynecologist (based on the appearance of the cervix under colposcopy). Utilizing confocal microscopy technology in the clinic would thus decrease the number of unnecessary biopsies. We then developed a deep learning algorithm that automatically and quantitatively assesses HPV contaminated and proliferating cells in histology images of biopsy sections. The automatic assessment of this procedure is important as it plays a significant role in differentiating between disease grades but forms a challenging and complex task and demands a large amount of time when performed manually by a pathologist. We demonstrated that this algorithm could help the pathologists to differentiate between different grades of cervical precancerous tissues. Our results are also more reproducible compared to other methods (like color deconvolution) that are widely being used in the field of digital pathology. The in vivo imaging and automatic image analysis algorithms demonstrated in the thesis can potentially enable i) real time diagnosis in the clinic, and ii) fast interpretation of histology images in a reproducible and cost-effective manner. While developed for cervical neoplasia, these methods could be extended to oral cavity, skin, and other epithelial tissue cancers.

description: We present experimental and theoretical results on a new regime in quantum dots in which the filling factor two-singlet state is replaced by new spin polarized phases. We make use of spin blockade spectroscopy to identify the transition to this new regime as a function of the number of electrons. The key experimental observation is a reversal of the phase in the systematic oscillation of the amplitude of Coulomb blockade peaks as the number of electrons is increased above a critical number. It is found theoretically that correlations are crucial to the existence of the new phases.

description: Central to the gravitational wave detection problem is the challenge of separating features in the data produced by astrophysical sources from features produced by the detector. Matched filtering provides an optimal solution for Gaussian noise, but in practice, transient noise excursions or ``glitches'' complicate the analysis. Detector diagnostics and coincidence tests can be used to veto many glitches which may otherwise be misinterpreted as gravitational wave signals. The glitches that remain can lead to long tails in the matched filter search statistics and drive up the detection threshold. Here we describe a Bayesian approach that incorporates a more realistic model for the instrument noise allowing for fluctuating noise levels that vary independently across frequency bands, and deterministic ``glitch fitting'' using wavelets as ``glitch templates'', the number of which is determined by a trans-dimensional Markov chain Monte Carlo algorithm. We demonstrate the method's effectiveness on simulated data containing low amplitude gravitational wave signals from inspiraling binary black hole systems, and simulated non-stationary and non-Gaussian noise comprised of a Gaussian component with the standard LIGO/Virgo spectrum, and injected glitches of various amplitude, prevalence, and variety. Glitch fitting allows us to detect significantly weaker signals than standard techniques.

description: Recherche La partie recherche porte sur deux œuvres autofictionnelles contemporaines : Déterrer les os de Fanie Demeule et Matricide de Katherine Raymond. À partir de thèmes tels que l’anorexie et le suicide sont étudiées chez les deux auteures les notions de silence et d’enfermement entretenus par la littérature scientifique. Il s’agit de repérer dans les textes les signes corporels et les actions des protagonistes afin d’en tirer un tableau clinique. Dans le cas de l’anorexie, l’objectif principal est de mettre en lumière les méthodes d’écriture et les signes de la corporalité. Dans le cas du suicide, ce sont plutôt les limites du langage et les actions menées par le corps dans une visée terminale qui sont abordées. L’analyse aboutit à l’idée d’une « trahison des corps », selon laquelle le corps est médiateur entre l’intime et le public. De manière générale, cette recherche s’intéresse à la dichotomie entre l’étude de cas psychologique et le rôle de l’autofiction en tant que contre- narration. Création La partie création de la thèse se présente sous la forme d’un récit autofictionnel dans lequel la narratrice explore sa propre descente vers la psychopathologie tout en utilisant le silence comme manœuvre de contrôle. Dans le but de dénoncer la pression de performance, la narratrice est placée dans des espaces clos, figures de l’enfermement et de l’aliénation causée par les stéréotypes et les troubles de santé mentale. De plus, elle soumet le lecteur à l’acte performatif de la confession psychiatrique. L’histoire, divisée en deux parties, est écrite sous forme de fragments illustrant chacun un signe de performance ou un signe précis de la sémiologie psychiatrique, soit l’analyse des signes corporels et des symptômes qui mènent à un diagnostic de trouble de santé mentale. La deuxième partie, aussi en fragments, explore la vérité derrière le système psychiatrique. Principalement, il s’agit de dégager les divers mécanismes qui arrivent à relier la performance scolaire et la performance des critères sémiologiques afin de mieux saisir l’émergence des signes cliniques.

description: The microscopic interface asymmetry of (001)-grown semiconductor heterostructures that gives rise to heavy-light hole coupling even at zero in-plane wave vector k||, modifies also the subband dispersion of confined electrons. Starting from a multiband envelope formulation we apply matrix perturbation theory to derive explicit expressions caused by this interface asymmetry, which in the 2×2 conduction band Hamiltonian appear as a warping and a spin-splitting term. The warping term results in an inequivalence of the dispersion along [110] and [1-10] as required by the microscopic C2v symmetry, while the spin-splitting term has the same structure as the corresponding term derived from the zinc-blende bulk inversion asymmetry. Implications with respect to spin-relaxation will be discussed.

description: This is the next step of uncovering the relation between string theory and exotic smooth R^4. Exotic smoothness of R^4 is correlated with D6 brane charges in IIA string theory. We construct wild embeddings of spheres and relate them to a class of topological quantum Dp-branes as well to KK theory. These branes emerge when there are non-trivial NS-NS H-fluxes where the topological classes are determined by wild embeddings S^2 -> S^3. Then wild embeddings of higher dimensional $p$-complexes into S^n correspond to Dp-branes. These wild embeddings as constructed by using gropes are basic objects to understand exotic smoothness as well Casson handles. Next we build C*-algebras corresponding to the embeddings. Finally we consider topological quantum D-branes as those which emerge from wild embeddings in question. We construct an action for these quantum D-branes and show that the classical limit agrees with the Born-Infeld action such that flat branes = usual embeddings.

description: Routers are one of the important entities in computer networks specially the Internet. Forwarding IP packets is a valuable and vital function in Internet routers. Routers extract destination IP address from packets and lookup those addresses in their own routing table. This task is called IP lookup. Internet address lookup is a challenging problem due to the increasing routing table sizes. Ternary Content-Addressable Memories (TCAMs) are becoming very popular for designing high-throughput address lookup-engines on routers: they are fast, cost-effective and simple to manage. Despite the TCAMs speed, their high power consumption is their major drawback. In this paper, Multilevel Enabling Technique (MLET), a power efficient TCAM based hardware architecture has been proposed. This scheme is employed after an Espresso-II minimization algorithm to achieve lower power consumption. The performance evaluation of the proposed approach shows that it can save considerable amount of routing table's power consumption.

description: Gapped excitation spectra of Andreev states in one- and two-dimensional normal systems in contacts with superconductors are analyzed in the presence of a parallel magnetic field. It is shown that in the ballistic regime there is a specific interplay between magnetic field spin splitting and the effect of a proximity-induced screening supercurrent which preserves time-reversal symmetry for certain groups of Andreev states. In this case the thermal conductance of the system remains suppressed well below the normal-state value in a rather wide range of magnetic fields approaching the critical fields of the superconductor.
The influence of Chinese character recognition skills on English reading and spelling development
Creators: name: Garforth, Kathryn Charlotte
Publisher: name: University of British Columbia

description: The present study examined literacy skills in 78 participants who had English as a second language (ESL) in grades 2-4, who had been attending school in English since kindergarten and had a Chinese language as their first language. These participants were tested on word reading, pseudoword reading, spelling, pseudoword spelling, and phonological awareness in English as well as word reading in Chinese. This study found that participants who had ESL were able to become proficient at reading and spelling in English. The participants’ Chinese character identification ability was correlated with their phonological awareness and the spelling of English and pseudowords. However, when including both phonological awareness and Chinese reading ability in the regression equations, Chinese character identification ability was only a significant predictor of pseudoword spelling ability. These results show the importance of understanding the literacy skills of an individual who has ESL in their first language as well as the language in which they are being instructed.

description: Using the 12m APEX telescope, we have detected redshifted emission from the 157.74micron [CII] line in the z=4.4074 quasar BRI1335-0417. The linewidth and redshift are in good agreement with previous observations of high-J CO line emission. We measure a [CII] line luminosity, L_[CII] = (16.4 +/- 2.6)x10^9 Lsun, making BRI~1335-0417 the most luminous, unlensed [CII] line emitter known at high-redshift. The [CII]-to-FIR luminosity ratio of (5.3+/-0.8)x10^-4 is ~3x higher than expected for an average object with a FIR luminosity L_FIR = 3.1x10^13 Lsun, if this ratio were to follow the trend observed in other FIR-bright galaxies that have been detected in [CII] line emission. These new data suggest that the scatter in the [CII]-to-FIR luminosity ratio could be larger than previously expected for high luminosity objects. BR1335-0417 has a similar FIR luminosity and [CII]/CO luminosity compared to local ULIRGS and appears to be a gas-rich merger forming stars at a rate of a few thousand solar masses per year.

description: Autonomous Ship Reality, (part of a webinar series) was a virtual event, organised in the context of on 08th-10th of March 2023, virtually, by BS group. The series were underlying the realization of autonomous ship operation both in technical and regulatory aspects. During this virtual session, participants and speakers talked about commercial autonomous ship reality from today’s and tomorrow’s perspectives by finding answers to the following questions: • Are the technological advancements sufficient for large implementations of autonomous systems?
 • What are the regulations for autonomous ships and how can they evolve?
 • How well are we ready for cyber security resilience? The virtual session was moderated by Prof. Nikolas Ventikos from NTUA, while presenters from SINTEF, Metrostar Management Corporation, IBM and other major institutions and companies shared their thoughts about autonomous shipping concepts, trends and challenges for the operation of MASS. Mr Photis Fotis Oikonomou from DANAOS, delivered a presentation entitled:”Reaching autonomous control in vessel operation (Conditional Automation Level 3)“. His presentation can be found here.
Dedication and Leadership
Creators: name: Hyde, Douglas
Publisher: name: University of Notre Dame

description: On March 14, 1948, Douglas Hyde handed in his resignation as the news editor of the _London Daily Worker_ and wrote 'the end' to twenty years of his life as a member of the Communist Party. A week later, in a written statement, Hyde announced that he had renounced Communism and, with his wife and children, was joining the Catholic Church.\u000a\u000aThe long pilgrimage from Communism to Christ carried Douglas Hyde from complete commitment to Marxism, to a questioning uneasiness about Soviet Russia's glaring contradictions of ideology and action, to a final rejection of the Party.\u000a\u000aIn DEDICATION AND LEADERSHIP, he advances the theory that although the goals and aims of Communism are antithetical to human dignity and the rights of the individual, there is much to be learned from communist methods, cadres and psychological motivation. Hyde describes the Communist mechanics of instilling dedication, the first prerequisite for leadership. Here is the complete rationale of party technique: how to stimulate the willingness to sacrifice; the advisibility of making big demands to insure a big response; the inspirational indoctrination; and the subtle conversion methods.\u000a\u000aIn this small book, so large with implications, Douglas Hyde comments on both Communist and Catholic potential and their lack of maximum effectiveness. He advocates positive Catholic action, not just a negative anti-Communism, and he points out that the guidelines are now down for a decisive choice between total Communism and a total Christianity.\u000a\u000aHere is a realistic approach to an acute problem uncolored by emotional propaganda, and here is a realistic answer on how to inspire dedication for leadership.\u000a\u000a\u00A9 University of Notre Dame\u000a\u000aCopyright for most content is held by The University of Notre Dame.

description: We consider quasi-stationary two-dimensional magnetic reconnection in a partially ionized incompressible plasma. We find that when the plasma is weakly ionized and the collisions between the ions and the neutral particles are significant, the transition to fast collisionless reconnection due to the Hall effect in the generalized Ohm's law is expected to occur at much lower values of the Lundquist number, as compared to a fully ionized plasma case. We estimate that these conditions for fast reconnection are satisfied in molecular clouds and in protostellar disks.

description: We derive an analytic, albeit approximate, expression for the ground state energy of N Coulomb interacting anyons with fractional statistics nu, 0$\lt$=|nu|$\lt$=1, confined in a two-dimensional well (with characteristic frequency omega0) and subjected to an external magnetic field (with cyclotron frequency omegac). We apply a variational principle combined with a regularization procedure which consists of fitting a cutoff parameter to existing exact analytical results in the noninteracting case, and to numerical calculations for electrons in quantum dots in the interacting case. The resulting expression depends upon parameters of the system |nu|,N,omega0,r0,aB and omegac, where r0 represents a characteristic unit length and aB the Bohr radius. Validity of the result is critically assessed by a comparison with exact, approximate, and numerical results from the literature.
All-Sky spectrally matched UBVRI-ZY and u'g'r'i'z' magnitudes for stars in the Tycho2 catalog

description: We present fitted UBVRI-ZY and u'g'r'i'z' magnitudes, spectral types and distances for 2.4M stars, derived from synthetic photometry of a library spectrum that best matches the Tycho2 BtVt, NOMAD Rn and 2MASS JHK_{2/S} catalog magnitudes. We present similarly synthesized multi-filter magnitudes, types and distances for 4.8M stars with 2MASS and SDSS photometry to g<16 within the Sloan survey region, for Landolt and Sloan primary standards, and for Sloan Northern (PT) and Southern secondary standards. The synthetic magnitude zeropoints for BtVt, UBVRI, ZvYv, JHK_{2/S}, JHK_{MKO}, Stromgren uvby, Sloan u'g'r'i'z' and ugriz are calibrated on 20 calspec spectrophotometric standards. The UBVRI and ugriz zeropoints have dispersions of 1--3%, for standards covering a range of color from -0.3 < V-I < 4.6; those for other filters are in the range 2--5%. The spectrally matched fits to Tycho2 stars provide estimated 1-sigma errors per star of ~0.2, 0.15, 0.12, 0.10 and 0.08 mags respectively in either UBVRI or u'g'r'i'z'; those for at least 70% of the SDSS survey region to g<16 have estimated 1-sigma errors per star of ~0.2, 0.06, 0.04, 0.04, 0.05 in u'g'r'i'z' or UBVRI. The density of Tycho2 stars, averaging about 60 stars per square degree, provides sufficient stars to enable automatic flux calibrations for most digital images with fields of view of 0.5 degree or more. Using several such standards per field, automatic flux calibration can be achieved to a few percent in any filter, at any airmass, in most workable observing conditions, to facilitate inter-comparison of data from different sites, telescopes and instruments.
