description: We propose a method for the fast generation of a quantum register of addressable qubits consisting of ultracold atoms stored in an optical lattice. Starting with a half filled lattice we remove every second lattice barrier by adiabatically switching on a superlattice potential which leads to a long wavelength lattice in the Mott insulator state with unit filling. The larger periodicity of the resulting lattice could make individual addressing of the atoms via an external laser feasible. We develop a Bose-Hubbard-like model for describing the dynamics of cold atoms in a lattice when doubling the lattice periodicity via the addition of a superlattice potential. The dynamics of the transition from a half filled to a commensurately filled lattice is analyzed numerically with the help of the Time Evolving Block Decimation algorithm and analytically using the Kibble-Zurek theory. We show that the time scale for the whole process, i.e. creating the half filled lattice and subsequent doubling of the lattice periodicity, is significantly faster than adiabatic direct quantum freezing of a superfluid into a Mott insulator for large lattice periods. Our method therefore provides a high fidelity quantum register of addressable qubits on a fast time scale.

Sustainability and hydro development in the Columbia River Basin
Creators: name: Toller, Susan B.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the concept of sustainability and the implications of large-scale hydroelectric development for the sustainability of communities in the Canadian portion of the Columbia River Basin. A literature review of sustainability provides a background for discussion and a working definition of sustainability is proposed for consideration throughout the study. An overview of the Canadian experience with hydro development and its ecological, social and economic impacts provides a context within which to consider issues related to sustainability. The Columbia River Basin is the setting of a case study of sustainability and hydro development in British Columbia. The Kootenay region has been affected by extensive hydro projects since the early 1900s on the Kootenay River and most significantly by large dams built on the Columbia system as a result of the Columbia River Treaty. Communities in the Kootenays have borne a large share of the impacts of these dams. The resulting degradation of fisheries, wildlife and forests has jeopardized the integrity of the region’s resource base and its capability to enhance the quality of life of those living within the Columbia River drainage basin. Future hydroelectric planning should address the sustainability of the ecological, social and economic systems affected by this land use change and ensure that local communities are included in project decision-making. Increased awareness of the consequences of large-scale hydro projects during planning stages may enable sustainable development to occur.

description: Physically motivated gravitational wave signals are needed in order to study the behaviour and efficacy of different data analysis methods seeking their detection. GravEn, short for Gravitational-wave Engine, is a MATLAB software package that simulates the sampled response of a gravitational wave detector to incident gravitational waves. Incident waves can be specified in a data file or chosen from among a group of pre-programmed types commonly used for establishing the detection efficiency of analysis methods used for LIGO data analysis. Every aspect of a desired signal can be specified, such as start time of the simulation (including inter-sample start times), wave amplitude, source orientation to line of sight, location of the source in the sky, etc. Supported interferometric detectors include LIGO, GEO, Virgo and TAMA.

description: The goal of the EU-funded UNICORE project is to develop a common code-base and toolchain that will enable software developers to rapidly create secure, portable, scalable, high-performance solutions starting from existing applications. The key to this is to compile an application into very light-weight virtual machines – known as unikernels – where there is no traditional operating system, only the specific bits of operating system functionality that the application needs. The resulting unikernels can then be deployed and run on standard high-volume servers or cloud computing infrastructure. In order to provide highest levels of flexibility during the Unikernels creation, it is necessary to define interfaces to interact with the internal components of the OS kernel. These interfaces will be used to expose existing OS kernel elements as a set of micro-libs (-libs). This decomposition of existing OS kernel components into -libs will define APIs to interact with Unikernels. E.g., APIs to schedulers, timer facilities, memory management, network stacks, etc. This deliverable will thus define library categories, and describe their associated APIs along with semantics annotations, in order to provide support for as many applications as possible. In addition, this deliverable will also identify the libraries that UNICORE will need to support the widest possible range of applications, along with a workplan as to how to quickly implement them. This deliverable is the first milestone in a series of three. Further improvements and information will be made through other milestones of this deliverable.
Nonlinear Debye screening in strongly-coupled plasmas

description: An ubiquitous property of plasmas is the so-called Debye shielding of the electrostatic potential. Important aspects of Debye screening concern, in particular, the investigation of non-linear charge screening effects taking place in strongly-coupled plasmas, that imply a reduction of the effective charge characterizing the Debye-Hückel potential. These effects are particularly relevant in dusty plasmas which are characterized by high-Z particles. The investigation of the effective interactions of these particles has attracted interest in recent years especially for numerical simulations. In this work we intend to analyze the consistency of the traditional mathematical model for the Debye screening. In particular, we intend to prove that the 3D Poisson equation involved in the DH model does not admit strong solutions. For this purpose a modified model is proposed which takes into account the effect of local plasma sheath (i.e., the local domain near test particles where the plasma must be considered discrete). Basic consequences of the model are discussed, which concern the asymptotic properties of the solutions determined both for weakly and strongly coupled plasmas. As an application the charge screening effect in strongly coupled plasmas is investigated and an explicit expression of the effective charge for the asymptotic DH potential is determined.

Measuring the absolute photo detection efficiency using photon number correlations

description: We present two methods for determining the absolute detection efficiency of photon-counting detectors directly from their singles rates under illumination from a nonclassical light source. One method is based on a continuous variable analogue to coincidence counting in discrete photon experiments, but does not actually rely on high detector time resolutions. The second method is based on difference detection which is a typical detection scheme in continuous variable quantum optics experiments. Since no coincidence detection is required with either method, they are useful for detection efficiency measurements of photo detectors with detector time resolutions far too low to resolve coincidence events.

On the double natured solutions to the two-temperature external soft photon comptonized accretion disks
Creators: name: Filho, Cesar Meirelles
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We have analyzed pair production in the innermost region of a two-temperature external soft photon comptonized accretion disk. We have shown that, if the viscosity parameter is greater than a temperature and r dependent critical value, the solution to the disk equation is double valued: one, advection dominated and the other, radiation dominated. When the viscosity parameter is below this critical value, the accretion rate has to be confined within a region limited by a minimum and a maximum accretion rates in order to have two steady state solutions. These critical accretion rates are shown to be dependent on r, on the temperature and on the viscosity parameter . Depending on the combination of the parameters, the advection dominated solution may not be physically consistent.

Neither Contextuality nor Nonlocality Admits Catalysts

description: We show that the resource theory of contextuality does not admit catalysts, i.e., there are no correlations that can enable an otherwise impossible resource conversion and still be recovered afterward. As a corollary, we observe that the same holds for nonlocality. As entanglement allows for catalysts, this adds a further example to the list of "anomalies of entanglement," showing that nonlocality and entanglement behave differently as resources. We also show that catalysis remains impossible even if, instead of classical randomness, we allow some more powerful behaviors to be used freely in the free transformations of the resource theory.

description: This volume covers Leg 68 of the cruises of the Drilling Vessel Glomar Challenger. The sixty-eighth cruise of Glomar Challenger was devoted to using the newly developed Hydraulic Piston Corer (HPC) to recover undisturbed, continuous sequences of unlithified sediment. We returned to the vicinities of two rotary-drilled sites (83 and 154). The stratigraphy of these sites indicated that uninterrupted sections of late Neogene and Quaternary sediment should exist at these locations. The ship left Curacao, Dutch Antilles, on 13 August 1979, cored for 11 days at Site 502, and transited from the Caribbean through the Panama Canal. Site 503, in the eastern equatorial Pacific was cored for seven days, and we then finally transited to Salinas, Ecuador. The general objectives of this cruise were to use the newly developed HPC to recover two undisturbed, continuous records of the late Neogene and Quaternary, one from the western Caribbean and the other from the eastern equatorial Pacific, and to test the coring capabilities of the HPC. The HPC had been successfully used only once before (Leg 64, Site 480), and it recovered a spectacular section of laminated (or varved) diatomites from the Gulf of California. This initial success inspired strong interest among the paleoceanographic community in using the HPC to continuously core high priority sites that were thought to have continuous records, to be pelagic or at least to contain a high biogenic component, and to be optimally located for answering important paleoceanographic questions. Previous attempts to obtain detailed records at some of these locations were plagued by spot coring, poor recovery, and badly disturbed sediment.

description: Οι μεταφορές αποτελούν μια υπηρεσία η οποία ικανοποιεί την καθημερινή ανάγκη των ανθρώπων για μετακίνηση. Η ανάγκη αυτή, στα πλαίσια της οικονομικής και τεχνολογικής ανάπτυξης παρουσιάζει αυξητικές τάσεις και έχει οδηγήσει έτσι στη συμφόρηση των συγκοινωνιακών υποδομών. Γι αυτό το λόγο οι συγκοινωνιολόγοι προσπαθούν να βρουν τρόπους επίλυσης των κυκλοφοριακών προβλημάτων μέσω της επίτευξης ισορροπίας μεταξύ της προσφοράς και της ζήτησης για μεταφορές. Οι σηματοδοτημένοι κόμβοι αποτελούν μια κρίσιμη παράμετρο η οποία έχει πολύ σημαντικό ρόλο στην αποτελεσματική λειτουργία του αστικού οδικού συστήματος. Ως σημεία καθυστέρησης μέσα σε ένα οδικό δίκτυο, γίνεται συνεχής προσπάθεια ώστε να επιτευχθεί η ορθή λειτουργία τους και για το λόγο αυτό ο προσδιορισμός βασικών παραμέτρων της κυκλοφορίας στη περιοχή των κόμβων έχει γίνει αντικείμενο εκτενούς έρευνας τις τελευταίες δεκαετίες. Στη συγκεκριμένη εργασία γίνεται μια προσπάθεια προσδιορισμού της ροής κορεσμού σε επτά διαφορετικούς κόμβους του αστικού δικτύου της Θεσσαλονίκης μέσω μετρήσεων. Η συλλογή των δεδομένων πραγματοποιείται με τη μεθοδο της βιντεοσκόπησης και η ανάλυσή τους ακολουθεί με τρεις διαφορετικές μεθόδους ( 4ο με 12ο, 4ο με τελευταίο και 5ο με τελευταίο όχημα στην ουρά). Τα αποτελέσματα των μεθόδων συγκρίνονται μεταξύ τους αλλά κυρίως με τη μέθοδο εκτίμησης της ροής κορεσμού που προτείνεται από το Highway Capacity Manual με εφαρμογή συντελεστών προσαρμογής κατάλληλων στις κυκλοφοριακές συνθήκες της πόλης.
description: Transport is a service that serves the daily human need for moving. This need, in the context of economic and technological development is increasing and therefore leads to congestion the transport infrastructure. For this reason, Transportation Engineers are trying to find ways of resolving traffic problems by achieving a balance between supply and demand for transport. Signalized intersections form a critical parameter which has a very important role in the effective operation of the urban road system. Being friction points in a road network, continuous effort has being made in order to achieve their proper operation and for this reason identifying the key traffic parameters of their operation, has been the subject of extensive research in recent times. In this thesis an attempt is made in order to determine the saturation flow through measurements in seven different signalized intersections in Thessaloniki. The data collection is performed by the method of videotaping and their analysis follows with three different methods (4th to 12th, 4th to last and 5th to the last vehicle of the queue). The results of all methods are compared with each other but mainly with the Highway Capacity Manual’s method of determining saturation flow through the application of adjustment factors appropriate to the city’s traffic conditions.

description: We study analytically and numerically the properties of one-dimensional chain of cold ions placed in a periodic potential of optical lattice and global harmonic potential of a trap. In close similarity with the Frenkel-Kontorova model, a transition from sliding to pinned phase takes place with the increase of the optical lattice potential for the density of ions incommensurate with the lattice period. Quantum fluctuations lead to a quantum phase transition and melting of pinned instanton glass phase at large values of dimensional Planck constant. The obtained results are also relevant for a Wigner crystal placed in a periodic potential.

description: We use time-resolved X-Photon Correlation Spectroscopy to investigate the slow dynamics of colloidal gels made of moderately attractive carbon black particles. We show that the slow dynamics is temporally heterogeneous and quantify its fluctuations by measuring the variance $χ$ of the instantaneous intensity correlation function. The amplitude of dynamical fluctuations has a non-monotonic dependence on scattering vector $q$, in stark contrast with recent experiments on strongly attractive colloidal gels [Duri and Cipelletti, \textit{Europhys. Lett.} \textbf{76}, 972 (2006)]. We propose a simple scaling argument for the $q$-dependence of fluctuations in glassy systems that rationalizes these findings.

title: Andean women's oppositional filmmaking : on and off-screen practices and politics
Creators: name: Seguí, Isabel
Publisher: name: University of St Andrews
Year: 2019

description: This thesis examines the work of three women, active in the production of oppositional cinema in the Andes in the last third of the 20th century: Beatriz Palacios, María Barea and Domitila Chungara. A focus on women’s contributions is crucial for the examination of political film practices and politics in artisanal production contexts. However, to date, the privileging of auteurist and formalist approaches in Latin American political cinema scholarship —which foreground the products over the processes— has overshadowed women’s involvement and, also, the active and creative participation of indigenous and working-class subjects. To correct this gap and to restore the emancipatory and collective dimension of these cinematic practices —consistent with the decolonial principles of Latin American Third Cinema— I focus on women’s labour in production, distribution, and exhibition. To allow for the excavation of this hidden and complex scenario, I use oral histories, personal archives, and interviews—counter-sites to the domain of state archives, cinephilic journals, and auteurist scholarship. Inscribing Palacios, Barea and Chungara’s practices and politics into official history contributes not only to recover their figures but to situate the research field of Andean political cinema in a more rigorous framework of understanding.

description: The status of exclusive two-body and three-body baryonic B decays is reviewed. The threshold enhancement effect in the dibaryon invariant mass and the angular distributions in the dibaryon rest frame are stressed and explained. Weak radiative baryonic B decays mediated by the electromagnetic penguin process $b\to sγ$ are discussed. Puzzles with the correlation observed in $B^-\to p\bar pK^-$ decay and the unexpectedly large rate observed for $B\toΛ_c\barΛ_cK$ are examined. The former may indicate that the $p\bar p$ system is produced through some intermediate states, while the latter implies the failure of naive factorization for $Λ\barΛK$ modes and may hint at the importance of final-state rescattering effects.

description: We use imaging polarimetry taken with the HST/ACS/HRC to explore the three dimensional structure of the circumstellar dust distribution around the red supergiant VY Canis Majoris. The polarization vectors of the nebulosity surrounding VY CMa show a strong centro-symmetric pattern in all directions except directly East and range from 10% - 80% in fractional polarization. In regions that are optically thin, and therefore likely have only single scattering, we use the fractional polarization and photometric color to locate the physical position of the dust along the line-of-sight. Most of the individual arc-like features and clumps seen in the intensity image are also features in the fractioanl polarization map. These features must be distinct geometric objects. If they were just local density enhancements, the fractional polarization would not change so abruptly at the edge of the feature. The location of these features in the ejecta of VY CMa using polarimetry provides a determination of their 3D geometry independent of, but in close agreement with, the results from our study of their kinematics (Paper I).

Nurses perceptions of their role working with people with severe mental handicaps in the community
Creators: name: Church, Lorna Jean
Publisher: name: University of British Columbia
Year: 2009

description: In British Columbia, people with mental handicaps are moving from institutions to living in the community and the British Columbia government has recently hired nurses to supervise the health care needs of these people. A body of knowledge on which to base the specific roles for nurses working with this client population is virtually non-existent. The purpose of this study was to explore and describe nurses’ perceptions of their role in working with individuals with severe mental handicaps in the community. This was a qualitative, descriptive study. Sampling was theoretical and twelve respondents were conveniently chosen. Data were collected through tape recorded, semi-structured interviews which were transcribed verbatim and analyzed using a process of inductive content analysis. Three distinct categories of nurse functions (with subcategories) emerged from the data: Collaboration, support, and teaching/learning. Collaboration included activities where the nurses worked with others and was divided into components of consultation, liaison, and team participation. Support included activities related to maintaining the health of or meeting the needs of clients and maintaining caregivers in their roles; it was comprised of advocating, assessing, documenting, planning, providing direct care, and relationship building. Teaching/learning encompassed activities related to teaching others and self-learning. Collaboration and teaching/learning were stated to be major roles by all of the nurses. The support components deemed to be important were advocacy, assessment, planning and relationship building. Most nurses were doing case management activities and saw this as their future focus. Travelling and documenting consumed much time and observation; communication, time management, and interpersonal skills were important for each aspect of the nurse’s role. The most difficult part of the job for most nurses was advocating for clients while collaborating with caregivers at the same time. A major frustration was expressed when nurses identified the clients’ health to be at risk but felt they were not listened to by caregivers. Nurses with advanced educational qualifications and experience working with individuals with severe mental handicaps appeared to be the most comfortable in the collaborative and teaching roles. Ongoing inservice education and support are required for nurses working with this client population and it is realistic to consider a baccalaureate degree as a minimum requirement for this job.

description: Aims. The purpose of this study is to examine the prediction that the deuterated H3+ ion, H2D+, can be found exclusively in the coldest regions of molecular cloud cores. This is also a feasibility study for the detection of the ground-state line of ortho-H2D+ at 372 GHz with APEX. Methods. The 1(10)-1(11) transition of H2D+ at 372 GHz was searched towards selected positions in the massive star forming cloud OriB9, in the dark cloud L183, and in the low- to intermediate mass star-forming cloud R CrA. Results. The line was detected in cold, prestellar cores in the regions of OriB9 and L183, but only upper limits were obtained towards other locations which either have elevated temperatures or contain a newly born star. The H2D+ detection towards OriB9 is the first one in a massive star-forming region. The fractional ortho-H2D+ abundances (relative to H2) are estimated to be about 1.0E-10 in two cold cores in OriB9, and 3.0E-10 in the cold core of L183. Conclusions. The H2D+ detection in OriB9 shows that also massive star forming regions contain very cold prestellar cores which probably have reached matured chemical composition characterized, e.g., by a high degree of deuterium fractionation. Besides as a tracer of the interior parts of prestellar cores, H2D+ may therefore be used to put contraints on the timescales related to massive star formation.

description: The issue of female madness as an act of defiance against patriarchal society is examined in the pioneering – yet overlooked by the male-dominated canon – plays Leonore; or, the World’s Own (1857) by Julia Ward Howe, Trifles (1916) by Susan Glaspell, Machinal (1928) by Sophie Treadwell, and ‘night, Mother (1983) by Marsha Norman. The four playwrights focus on the devastating impact of socially-constructed gender notions on women’s mental and physical health, and challenge the dominant patriarchal ideology which perpetuates female dependence and suffering. Additionally, they call attention to female madness as a product of the emergence of social sciences and demonstrate the unexpected ways in which women often function when they succeed in assuming the subject position in life. Female violence in the plays is approached from a feminist viewpoint and recognized as women’s desperate attempt to become visible within a hostile establishment that condemns them to a marginal, slave-like existence. Finally, despite writing at different times, the four playwrights underscore the imperative need for sociocultural transformation, and question whether women can ever really be ontologically satisfied or “sane” within a ruthless, male-accommodating system.

Οι τέσσερις συγγραφείς εστιάζουν στην καταστροφική επίδραση των κοινωνικά κατασκευασμένων αντιλήψεων περί φύλου στηv ψυχική και σωματική υγεία της γυναίκας και αμφισβητούν την κυρίαρχη πατριαρχική ιδεολογία, η οποία ευθύνεται για τη διαιώνιση του γυναικείου πόνου. Επιπλέον, οι συγγραφείς επισημαίνουν την εμφάνιση της ιδέας της γυναικείας «τρέλας» παράλληλα με αυτή των κοινωνικών επιστημών και παρουσιάζουν τη συχνά απρόβλεπτη συμπεριφορά των γυναικών όταν αναλαμβάνουν το ρόλο του υποκειμένου. Η γυναικεία βία προσεγγίζεται στα θεατρικά από φεμινιστική οπτική και αναγνωρίζεται ως απέλπιδα προσπάθεια των γυναικών να γίνουν ορατές μέσα σε ένα εχθρικό περιβάλλον που τις καταδικάζει στο περιθώριο. Τέλος, παρότι έγραψαν σε διαφορετικές εποχές, οι τέσσερις θεατρικές συγγραφείς τονίζουν την επιτακτική ανάγκη για κοινωνικοπολιτισμική αλλαγή και διερωτώνται αν οι γυναίκες μπορούν να είναι ποτέ πραγματικά οντολογικά πλήρεις ή ψυχικά υγιείς μέσα σε ένα αδίστακτο φαλλοκρατικό σύστημα.

description: After 3 1/2 years, the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) is moving into its final stages. The United States and several other nations have presented separate proposals for comprehensive agricultural trade reform. The U.S. proposal seeks to make major reforms in import access, export competition. Internal support policies, and sanitary and phytosanitary measures. If implemented, this proposal would produce higher world market prices, lower taxpayer costs, and, in some key countries, significantly lower consumer prices.

description: A number of different methods have been proposed to identify unanticipated burst sources of gravitational waves in data arising from LIGO and other gravitational wave detectors. When confronted with such a wide variety of methods one is moved to ask if they are all necessary, i.e. given detector data that is assumed to have no gravitational wave signals present, do they generally identify the same events with the same efficiency, or do they each 'see' different things in the detector? Here we consider three different methods, which have been used within the LIGO Scientific Collaboration as part of its search for unanticipated gravitational wave bursts. We find that each of these three different methods developed for identifying candidate gravitational wave burst sources are, in fact, attuned to significantly different features in detector data, suggesting that they may provide largely independent lists of candidate gravitational wave burst events.

A phenomenological study on the experiences of aging parents caring for their adult son/daughter with a disability
Creators: name: Petrica, Joni Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: With the continued movement toward deinstitu tionalization, and community—based health care, professionals will see a rise in the number of aging parents caring for their adult son/daughter with a disability. Little research exists to understand the needs of aging parents, and what is available reflects quantitative studies that primarily focus on parents’ feelings of stress and burden, and their future planning concerns for the adult child. In order to discover and describe the totality of aging parents’ experiences caring for an adult child with a disability, this study used a phenomenological approach to elicit qualitative information. Both mothers and fathers were interviewed, and the results indicated that the presence of a child with a disability in the lives of these parents has contributed positively to parents’ sense of self, their perceptions of themselves as parents, and the meanings and interpretations they give to their lives in spite of - or as a result of — having cared for a disabled child. Parents’ accounts of their experiences with professionals also suggested the value of social workers listening to parents’ needs and concerns in the context of a lifetime of struggles and demands, achievements and accomplishments. In this way, social workers are better able to help parents address their own developmental needs of aging by providing sensitive and timely programs and services that address parents’ unique challenges raising an adult child with a disability.

description: We present $K$-band spectra of the near infrared counterparts to IRS2E and IRS2W which is associated with the ultracompact HII region W51d, both of them embedded sources in the Galactic compact HII region W51 IRS2. The high spatial resolution observations were obtained with the laser guide star facility and Near infrared Integral Field Spectrograph (NIFS) mounted at the Gemini North observatory. The spectrum of the ionizing source of W51d shows the photospheric features NIII (21155 Å) in emission and HeII (21897 Å) in absorption which lead us to classify it as an young O3 type star. We detected CO overtone in emission at 23000 Åin the spectrum of IRS2E, suggesting that it is a massive young object still surrounded by an accretion disc, probably transitioning from the hot core phase to an ultracompact HII region.

description: Im Vergleich zum Vorjahr konnte im Jahr 2018 im NRZ für gramnegative Krankenhauserreger erneut ein deutlicher Anstieg der Einsendungen und der Carbapenemase-Nachweise verzeichnet werden. Wie im Epidemiologischen Bulletin 31/2019 berichtet wird weist Enterobacterales mit OXA-48 weiterhin die Carbapenemase mit der höchsten Prävalenz auf, in P. aeruginosa ist VIM-2 und in A. baumannii OXA-23 nach wie vor die am häufigsten nachgewiesene Carbapenemase. In allen beobachteten Speziesgruppen sind eine zunehmende Diversifizierung von Carbapenemasen und eine Zunahme von Fällen mit mehr als einer Carbapenemase zu beobachten. Auffällig ist der starke Anstieg von NDM-5- oder OXA-244-produzierenden E. coli, deren Nachweiszahlen sich im Vergleich zu 2017 nahezu verdoppelt bzw. verdreifacht haben. Dies zeigt, dass die intensivierte, molekulare Surveillance von Carbapenemasen in Deutschland unabdingbar ist, um derartige Entwicklungen rechtzeitig zu erfassen, ihre Hintergründe zu verstehen und daraus geeignete Präventionsmaßnahmen ableiten zu können.
Superstring standard model from Z_{12-I} orbifold compactification with and without exotics, and effective R-parity

description: We construct a supersymmetric standard model in the context of the $Z_{12-I}$ orbifold compactification of the heterotic string theory. The gauge group is $SU(3)_c\times SU(2)_L\times U(1)_Y\times U(1)^4\times[SO(10)\times U(1)^3]'$. We obtain three chiral families, $3\times\{Q,d^c,u^c,L,e^c,ν^c\}$, and Higgs doublets. There are numerous neutral singlets many of which can have VEVs so that low energy phenomenology on Yukawa couplings can be satisfied. In one assignment (Model E) of the electroweak hypercharge, we obtain the string scale value of $sin^2θ_W^0={3/8}$ and another exactly massless {\it exphoton} (in addition to the photon) coupling to exotic particles only. There are color triplet and anti-triplet exotics, $α$ and $\barα$, $SU(2)_L$ doublet exotics, $δ$ and $\barδ$, and $SU(3)_c\times SU(2)_L$ singlet but $Y={2/3},-{1/3},-{2/3},{1/3}$ exotics, $ξ,η,\barξ, \barη$. We show that all these vector-like exotics achieve heavy masses by appropriate VEVs of neutral singlets. One can find an effective R-parity between light (electroweak scale) particles so that proton and the LSP can live sufficiently long. In another assignment (Model S) of the electroweak hypercharge, there does not appear any exotic particle but $sin^2θ_W^0={3/14}$.

Magnetic Field Confinement in the Corona: The Role of Magnetic Helicity Accumulation

description: A loss of magnetic field confinement is believed to be the cause of coronal mass ejections (CMEs), a major form of solar activity in the corona. The mechanisms for magnetic energy storage are crucial in understanding how a field may possess enough free energy to overcome the Aly limit and open up. Previously, we have pointed out that the accumulation of magnetic helicity in the corona plays a significant role in storing magnetic energy. In this paper, we investigate another hydromagnetic consequence of magnetic-helicity accumulation. We propose a conjecture that there is an upper bound on the total magnetic helicity that a force-free field can contain. This is directly related to the hydromagnetic property that force-free fields in unbounded space have to be self-confining. Although a mathematical proof of this conjecture for any field configuration is formidable, its plausibility can be demonstrated with the properties of several families of power-law, axisymmetric force-free fields. We put forth mathematical evidence, as well as numerical, indicating that an upper bound on the magnetic helicity may exist for such fields. Thus, the accumulation of magnetic helicity in excess of this upper bound would initiate a non-equilibrium situation, resulting in a CME expulsion as a natural product of coronal evolution.

description: Average production costs and returns per planted acre of rice are presented for 1988 with and without the direct effects of Government programs. When the direct effects of programs Are included in the estimates, gross returns, production costs, and net returns are all higher. This analysis is the first time the U.S. Department of Agriculture (USDA) has prepared such estimates for any commodity because the necessary data were not available in the past. Such data are available only for rice.
