Single Production of Fourth Family Sneutrino via RPV Couplings at Linear Colliders

The single production of fourth family sneutrino $\tilde{\nu}_{4}$ via R-parity violating interactions in electron-positron collisions has been investigated. We study the decays of $\tilde{\nu}_{4}$ into different flavor dilepton $e^{\pm}\mu^{\mp}$ via R-parity violation. It is shown that R-parity violating couplings $(\lambda_{411},\lambda_{412})$ down to 0.001 will be reachable at future linear colliders which would provide better accuracy comparing to the indirect measurements as complementary to the LHC results.Comment: 11 pages, 6 figure

General entanglement

The paper contains a brief review of an approach to quantum entanglement based on analysis of dynamic symmetry of systems and quantum uncertainties, accompanying the measurement of mean value of certain basic observables. The latter are defined in terms of the orthogonal basis of Lie algebra, corresponding to the dynamic symmetry group. We discuss the relativity of entanglement with respect to the choice of basic observables and a way of stabilization of robust entanglement in physical systems.Comment: 7 pages, 1 figure,1 tabe, will be published in special issue of Journal of Physics (Conference Series) with Proceedings of CEWQO-200

Comparison of two ELISA methods for detection of antibodies against Footand- Mouth Disease virus of cattle breeds in Turkey

ΔΕΝ ΥΠΑΡΧΕΙ ΠΕΡΙΛΗΨΗ ΣΤΑ ΕΛΛΗΝΙΚΑThe study was conducted using two ELISA methods - the liquid phase blocking ELISA (LPBE) and solid phase competition ELISA (SPCE) for the detection of foot-and-mouth disease virus (FMDV) serotype A- and O-specific antibodies of different cattle breeds in Turkey. These methods were compared in 426 cattle previously vaccinated with oil-adjuvanted bivalent vaccine as well as in sera from 40 cattle with no history of foot-and-mouth disease infection or vaccination. The results were found that SPCE had a better specificity (serotype A; 100% and serotype O; 97.50%) than LPBE (serotype A 95.00% and serotype O 92.50%). Sensitivity of SPCE had also better values (serotype A; 99.30% and serotype O; 98.59%) than LPBE (serotype A; 97.89% and serotype O; 96.48%). The results of the present study showed that the SPCE method is more reliable than LPBE

Asperities and barriers on the seismogenic zone in North Chile: state-of-the-art after the 2007 Mw 7.7 Tocopilla earthquake inferred by GPS and InSAR data

The Mw 7.7 2007 November 14 earthquake had an epicentre located close to the city of Tocopilla, at the southern end of a known seismic gap in North Chile. Through modelling of Global Positioning System (GPS) and radar interferometry (InSAR) data, we show that this event ruptured the deeper part of the seismogenic interface (30–50 km) and did not reach the surface. The earthquake initiated at the hypocentre and was arrested ~150 km south, beneath the Mejillones Peninsula, an area already identified as an important structural barrier between two segments of the Peru–Chile subduction zone. Our preferred models for the Tocopilla main shock show slip concentrated in two main asperities, consistent with previous inversions of seismological data. Slip appears to have propagated towards relatively shallow depths at its southern extremity, under the Mejillones Peninsula. Our analysis of post-seismic deformation suggests that small but still significant post-seismic slip occurred within the first 10 d after the main shock, and that it was mostly concentrated at the southern end of the rupture. The post-seismic deformation occurring in this period represents ~12–19 per cent of the coseismic deformation, of which ~30–55 per cent has been released aseismically. Post-seismic slip appears to concentrate within regions that exhibit low coseismic slip, suggesting that the afterslip distribution during the first month of the post-seismic interval complements the coseismic slip. The 2007 Tocopilla earthquake released only ~2.5 per cent of the moment deficit accumulated on the interface during the past 130 yr and may be regarded as a possible precursor of a larger subduction earthquake rupturing partially or completely the 500-km-long North Chile seismic gap

Comments on glueballinos (R0 particles) and R0 searches

We propose a search strategy for the light R0 (glueballino) particle suggested by G.Farrar in connection with the light gluino scenario. The basic idea is to moderate and stop the R0 particles and then observe their decay to almost monochromatic pions - at an appropriate time delay relative to a primary collision event, where a gluino jet, likely to fragment into the R0, was produced. This technique is optimized at colliders and depends on qualitative features of the R0 hadronic interactions which we discuss in detail.Comment: LaTeX, 28 page

Hypericum perforatum plant cells reduce Agrobacterium viability during co-cultivation

Plant recalcitrance is the major barrier in developing Agrobacterium-mediated transformation protocols for several important plant species. Despite the substantial knowledge of T-DNA transfer process, very little is known about the factors leading to the plant recalcitrance. Here, we analyzed the basis of Hypericum perforatum L. (HP) recalcitrance to Agrobacterium-mediated transformation using cell suspension culture. When challenged with Agrobacterium, HP cells swiftly produced an intense oxidative burst, a typical reaction of plant defense. Agrobacterium viability started to decline and reached 99% mortality within 12 h, while the plant cells did not suffer apoptotic process. This is the first evidence showing that the reduction of Agrobacterium viability during co-cultivation with recalcitrant plant cells can affect transformation

Application of the Hybrid-Maize model for limits to maize productivity analysis in a semiarid environment

Effects of meteorological variables on crop production can be evaluated using various models. We have evaluated the ability of the Hybrid-Maize model to simulate growth, development and grain yield of maize (Zea mays L.) cultivated on the Loess Plateau, China, and applied it to assess effects of meteorological variations on the performance of maize under rain-fed and irrigated conditions. The model was calibrated and evaluated with data obtained from field experiments performed in 2007 and 2008, then applied to yield determinants using daily weather data for 2005-2009, in simulations under both rain-fed and irrigated conditions. The model accurately simulated Leaf Area Index , biomass, and soil water data from the field experiments in both years, with normalized percentage root mean square errors < 25 %. Gr.Y and yield components were also accurately simulated, with prediction deviations ranging from -2.3 % to 22.0 % for both years. According to the simulations, the maize potential productivity averaged 9.7 t ha-1 under rain-fed conditions and 11.53 t ha-1 under irrigated conditions, and the average rain-fed yield was 1.83 t ha-1 less than the average potential yield with irrigation. Soil moisture status analysis demonstrated that substantial potential yield may have been lost due to water stress under rain-fed conditions

The Conundrum of Low Achievement and Feedback for Learning

The literature on improving student engagement with assessment and feedback has a tendency to treat all students as if they are the same. Students with lower levels of attainment are generally underrepresented within empirical studies and their feedback behaviours are less well understood. The recent drive to improve student assessment and feedback literacy and the move from ‘feedback’ being information about a task to being a process of understanding and using performance information is a larger conceptual leap for some students than others. In this paper, we consider issues surrounding the transition to new modes of feedback, focusing on what is needed for those who find study difficult and persistently are disappointed by their levels of attainment, to benefit from and take advantage of our feedback pedagogies. We examine literature advocating strategies such as increasing agency, using praise, developing feedback literacy and cultivating a growth mind-set. We argue that students who underachieve may benefit from strong relationships with educators and peers; exposure to feedback rich, low stakes environments, which permit repeated integrations of practice and feedback and building feedback literacy through peer assessment activities
