    Harmonic analysis of irradiation asymmetry for cylindrical implosions driven by high-frequency rotating ion beams

    Cylindrical implosions driven by intense heavy ions beams should be instrumental in a near future to study High Energy Density Matter. By rotating the beam by means of a high frequency wobbler, it should be possible to deposit energy in the outer layers of a cylinder, compressing the material deposited in its core. The beam temporal profile should however generate an inevitable irradiation asymmetry likely to feed the Rayleigh-Taylor instability (RTI) during the implosion phase. In this paper, we compute the Fourier components of the target irradiation in order to make the junction with previous works on RTI performed in this setting. Implementing a 1D and 2D beam models, we find these components can be expressed exactly in terms of the Fourier transform of the temporal beam profile. If TT is the beam duration and Ω\Omega its rotation frequency, "magic products" ΩT\Omega T can be identified which cancel the first harmonic of the deposited density, resulting in an improved irradiation symmetry.Comment: 19 pages, 8 figures, to appear in PR

    Joseph E. Stiglitz, Rewriting the Rules of the American Economy, An Agenda for Growth and Shared Prosperity

    Abstract. The rules of game are fair if they are fair for all the economic agents; but if rules favor certain segment of society more than the others, then not to change rules would be grossly unfair. The rules that exacerbate the gap between the rich and the poor and make equality of opportunities conspicuously absent are not fair at all.  These unfair rules give birth to poverty and inequality and the issue of poverty and inequality is of utmost importance. For instance, in April 2013, the Board of Executive Director of the World Bank adopted two goals: end global extreme poverty and promote shared prosperity. The World Bank Group published a comprehensive report titled ‘Talking on Inequality’ in 2016.Keywords. American economy, Economic growth.JEL. A10

    EAST: Energy Efficient Adaptive Scheme for Transmission in Wireless Sensor Networks

    Full text link
    In this paper, we propose Energy-efficient Adaptive Scheme for Transmission (EAST) in WSNs. EAST is IEEE 802.15.4 standard compliant. In this approach, open-loop is used for temperature-aware link quality estimation and compensation. Whereas, closed-loop feedback helps to divide network into three logical regions to minimize overhead of control packets on basis of Threshold transmitter power loss (RSSIloss) for each region and current number of neighbor nodes that help to adapt transmit power according to link quality changes due to temperature variation. Simulation results show that propose scheme; EAST effectively adapts transmission power to changing link quality with less control packets overhead and energy consumption compared to classical approach with single region in which maximum transmitter power assigned to compensate temperature variation

    βC1 of chili leaf curl betasatellite is a pathogenicity determinant

    <p/> <p>Background</p> <p>Cotton leaf curl disease in the Indian subcontinent is associated with several distinct begomoviruses that interact with a disease-specific DNA satellite named Cotton leaf curl Multan betasatellite (CLCuMB). However, we have recently reported that Chili leaf curl betasatellite (ChLCB) is also occasionally found associated with the disease in Pakistan. The question as to whether ChLCB contributes to the development of disease symptoms such as leaf curling and enations remain to be answered. We have previously shown that the expression of βC1 of CLCuMB develops all symptoms of cotton leaf curl disease in <it>Nicotiana benthamiana </it>when expressed from PVX vector.</p> <p>Findings</p> <p>The role of ChLCB in the induction of typical disease symptoms was studied by its expression from PVX vector in <it>N. benthamiana</it>. The expression of βC1 from PVX vector developed severe leaf curl symptoms and leaf-like enations that resemble the phenotype induced by βC1 of CLCuMB.</p> <p>Conclusions</p> <p>The results presented here show that the expression of βC1 of ChLCB from PVX vector exhibit phenotype typical of cotton leaf curl and therefore ChLCB may contribute to the disease symptoms.</p

    The growth of vehicle every year give impact to traffic intersection performance. The impact of trrafic such as vehicle queueing , traffic jam , rise in delay time and also increase travel time could be caused by traffic control system no effective because the increasing by traffic volumeThis research is conducted in one of Major Street in Palu, namely at Samratulangi – Sudirman Street street is the intersection between Hj. Hayyun – Cik Ditiro Street.In this research, the analyzed by using Manual Kapasitas Jalan Indonesia ( MKJI).From result of analysis by using MKJI , got intersection performance at condition of morning peak reside at service of level C with queue length is equal to 38,73, in the peak day has level of service F with queue length is equal to 65,04 m and afternoon peak with level of service E where the queueing length is 70,07 m. According to value of level of service on the this intersection had shown that traffic control system 2 (two) stage was not effective agai
