Role of 12-oxo-phytodienoic acid and β-glucan Elicitor in Prevention of Fungal Infection in Mnium cuspidatum

The moss, Mnium cuspidatum and the fungus, Pythium irregulare, were used to study the role of the plant hormone, 12-oxo-phytodienoic acid (OPDA) and the elicitor, β-glucan in the prevention of fungal infection. Each compound was applied before the inoculation of a fungal cube and a combination of qualitative and quantitative analyses were done in order to determine the degree of infection within the moss. It was found that P. irregulare does infect and kill the cells of M. cuspidatum through chloroplast degradation, stem browning and appressoria injections within 24 hours. The pre-application of OPDA or β-glucan were unable to prevent or lessen the fungal infection. In future experiments, it is recommended that a cellophane cover be applied before the application of the moss and fungi so that the fungi does not grow into the medium and the moss does not soften from contact with the agar gel

Potential Economic Consequences of Local Nonconformity to Regional Land Use and Transportation Plans Using a Spatial Economic Model

To achieve the greenhouse gas (GHG) reduction targets that are required by California’s global warming legislation (AB32), the state of California has determined that recent growth trends in vehicle miles traveled (VMT) must be curtailed. In recognition of this, Senate Bill 375 (SB375) requires regional governments to develop land use and transportation plans or Sustainable Community Strategies (SCSs) that will achieve regional GHG targets largely though reduced VMT. Although the bill requires such a plan, it does not require local governments to adopt general plans that conform to this plan. In California, it is local, not regional, governments that have authority over land development decisions. Instead, SB375 relies on democratic participatory processes and relatively modest financial and regulatory incentives for SCS implementation. As a result, it is quite possible that some local governments within a region may decide not to conform to their SCS. In this study, a spatial economic model (PECAS) is applied in the Sacramento region (California, U.S.) to understand what the economic and equity consequences might be to jurisdictions that do and do not implement SCS land use plans in a region. An understanding of these consequences provides insight into jurisdictions’ motivations for compliance and thus, strategies for more effective implementation of SB375

Generalized parity measurements

Measurements play an important role in quantum computing (QC), by either providing the nonlinearity required for two-qubit gates (linear optics QC), or by implementing a quantum algorithm using single-qubit measurements on a highly entangled initial state (cluster state QC). Parity measurements can be used as building blocks for preparing arbitrary stabilizer states, and, together with 1-qubit gates are universal for quantum computing. Here we generalize parity gates by using a higher dimensional (qudit) ancilla. This enables us to go beyond the stabilizer/graph state formalism and prepare other types of multi-particle entangled states. The generalized parity module introduced here can prepare in one-shot, heralded by the outcome of the ancilla, a large class of entangled states, including GHZ_n, W_n, Dicke states D_{n,k}, and, more generally, certain sums of Dicke states, like G_n states used in secret sharing. For W_n states it provides an exponential gain compared to linear optics based methods.Comment: 7 pages, 1 fig; updated to the published versio

Engineering entanglement for metrology with rotating matter waves

Entangled states of rotating, trapped ultracold bosons form a very promising scenario for quantum metrology. In order to employ such states for metrology, it is vital to understand their detailed form and the enhanced accuracy with which they could measure phase, in this case generated through rotation. In this work, we study the rotation of ultracold bosons in an asymmetric trapping potential beyond the lowest Landau level (LLL) approximation. We demonstrate that while the LLL can identify reasonably the critical frequency for a quantum phase transition and entangled state generation, it is vital to go beyond the LLL to identify the details of the state and quantify the quantum Fisher information (which bounds the accuracy of the phase measurement). We thus identify a new parameter regime for useful entangled state generation, amenable to experimental investigation

Entanglement of superconducting charge qubits by homodyne measurement

We present a scheme by which projective homodyne measurement of a microwave resonator can be used to generate entanglement between two superconducting charge qubits coupled to this resonator. The non-interacting qubits are initialised in a product of their ground states, the resonator is initialised in a coherent field state, and the state of the system is allowed to evolve under a rotating wave Hamiltonian. Making a homodyne measurement on the resonator at a given time projects the qubits into an state of the form (|gg> + exp(-i phi)|ee>)/sqrt(2). This protocol can produce states with a fidelity as high as required, with a probability approaching 0.5. Although the system described is one that can be used to display revival in the qubit oscillations, we show that the entanglement procedure works at much shorter timescales.Comment: 17 pages, 7 figure

Differences Between Women-Owned Home-Based & Office-Based Businesses: An Exploratory Study

In this paper, the differences between women-owned home-based and office-based businesses are explored through an empirical study of 150 attendees of small business workshops and conferences.  Home-based  and office-based  business  locations  are compared  based  on  an analysis of the following  variables: prior industry and managerial experience, business plan development, length of time spent planning the business, adequacy of starting capital, income level, self-reported  success  rating ,    and financial   and personal   satisfaction  levels.    Frequency data  were  assembled   and  characteristics   identified.   Cross-tabulations   and  Chi  Square analysis  of  expected  and  actual  related factors   was  performed   with  significant  factors identified. Results of this exploratory study suggest that women entrepreneurs with home­ based businesses have less employees, work fewer  hours, are more likely to hold second jobs, are not involved in international business activity, and are most often located in suburban and rural geographical  areas.   Although  there were no significant  differences  in the business planning  activities  between  home-based  and  office-based  women  entrepreneurs,  the study results indicate that home-based businesses generate  less income, are not perceived  to be as successful, and  are not as financially  satisfying  to the entrepreneur  as are office-based businesses
