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 is the beam duration and its rotation
frequency, "magic products" 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
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

Evaluating tools to support a new practical classification of diabetes: excellent control may represent misdiagnosis and omission from disease registers is associated with worse control.
To conduct a service evaluation of usability and utility on-line clinical audit tools developed as part of a UK Classification of Diabetes project to improve the categorisation and ultimately management of diabetes
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
Efketifitas Simpang Bersinyal Dengan Sistem Pengaturan Dua Fase Pada Jalan Utama Di Kota Palu (Studi Kasus: Simpang Samratulangi – Sudirman- Cik Ditiro- Haji Hayyun)
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
