Research ArticleOpen accessEvery word in the titleA Light-Weight Service Discovery Protocol for Ad Hoc NetworksRanwa Al Mallah, Alejandro QuinteroProblem statement: In mobile ad hoc networks devices do not rely on a fixed infrastructure and thus have to be self-organizing. This gives rise to various challenges to network applications. Existing service discovery protocols fall short of accommodating the complexities of the ad-hoc environment. However, the performance of distributed service discovery architectures that rely on a virtual backbone for locating … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,343 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Exposure to Various Durations of Light on Serum Insulin-Like Growth Factor-I in Prepubertal Holstein HeifersL.J. Spicer, B.A. Buchanan, L.T. Chapin, H.A. TuckerOur objective was to determine if prolonged exposure to various durations of light (i.e., photoperiod) would affect serum IGF-I concentrations in heifers. Thus, 16 Holstein heifers, 2 to 4 mo of age, were exposed during a 5-wk pretreatment period to 12 h of cool-white fluorescent light (L) at an intensity of 1200 lux and 12 h of dark (D).

Research ArticleOpen accessEvery word in the titlePoly(3,4-Ethylenedioxythiophene):Poly(4-Styrenesulfonate) Anode for ITO-Free Organic Light-Emitting DiodesKeanchuan Lee, Martin WeisOrganic Light-Emitting Diodes (OLEDs) devices using flexible substrates are envisioned for flexible, low-cost and roll-to-roll mass production. However, transparent conductive oxides such as indium tin oxide (ITO) do not fit the requirements of flexible devices, fabricated without vacuum-based technology. Hence, conductive polymer poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) has been proposed as an alternative approach to transparent conductive electrodes. The secondary doping of PEDOT:PSS … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Jan 2018 · 7,599 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUSING LIGHT TO SEE NEUTRONS AND ACCESSING THE 2D HIGH RESOLUTION: BAROTRON: A NEW PULSE FOR NEUTRON SCATTERINGPatrick Baroni, Laurence NoirezSince first years of exploitation in 1960-70, neutron scattering has emerged as a unique and non-destructive means to probing inside matter properties at the nanometer length scales.
