A biochemical model of photosynthetic CO2 assimilation in leaves of C3 species

by G. D. Farquhar, S. Von Caemmerer, J. A. Berry - Planta , 1980
"... Abstract. Various aspects of the biochemistry of photosynthetic carbon assimilation in C3 plants are integrated into a form compatible with studies of gas exchange in leaves. These aspects include the kinetic properties of ribulose bisphosphate carboxylase-oxygenase; the requirements of the photosyn ..."

of the photosynthetic carbon reduction and photorespiratory carbon oxida-tion cycles for reduced pyridine nucleotides; the de-pendence of electron transport on photon flux and the presence of a temperature dependent upper limit to electron transport. The measurements of gas ex-change with which the model outputs may

Improving round-trip time estimates in reliable transport protocols

by Phil Karn, Craig Partridge, Bolt Beranek - ACM Transactions on Computer Systems , 1987
"... As a reliable, end-to-end transport protocol, the Transmission Control Protocol (TCP) uses positive acknowledgements and retransmission to guarantee delivery. TCP implementations are expected to measure and adapt to changing round-trip delay so that their retransmission behavior balances user throug ..."

M-TCP: TCP for Mobile Cellular Networks

by Kevin Brown, Suresh Singh - Computer Communication Review , 1997
"... Transport connections set up over wireless links are frequently plagued by problems such as { high bit error rate (BER), frequent disconnections of the mobile user, and low wireless bandwidth that may change dynamically. In this paper, we study the e ects of frequent disconnections and low variable ..."

(R)-N-Methyl-3-(3-125I-pyridin-2-yloxy)-3-phenylpropan-1-amine ([125I]PYINXT) : a novel probe for norepinephrine transporters (NET)

by B. Lakshmi, M-p. Kung, B. Lieberman, J. Zhao, R. Waterhouse, H. F. Kung
"... Alterations in the serotonin and norepinephrine neuronal functions have been observed in patients with major depression. Several antidepressants bind to both serotonin transporters (SERT) and norepinephrine transporters (NET). The ability to image NET in the human brain would be a useful step toward ..."

Abstract - Cited by 228 (5 self) - Add to MetaCart
. Anthropogenic sources of black carbon, although distributed globally, are most concentrated in the tropics where solar irradiance is highest. Black carbon is often transported over long distances, mixing with other aerosols along the way. The aerosol mix can form transcontinental plumes of atmospheric brown

Norepinephrine Transporter (NET), Serotonin Transporter (SERT), Vesicular Monoamine Transporter (VMAT2) and Organic Cation Transporters (OCT1, 2 and EMT) in Human Placenta from

by Normotensive Pregnancies, B. Bottalico, I. Larsson, J. Brodszki, E. Hern, S. R. Hansson , 2003
"... Pre-eclampsia is one of the most common causes of perinatal and maternal morbidity and mortality. High blood pressure and proteinuria are important clinical signs of pre-eclampsia. Sympathetic overactivity and elevated level of circulating vaso active substances, such as monoamines has been shown. E ..."
Abstract - Add to MetaCart
. Extracellular concentrations of monoamines are normally kept low by specific transporter proteins of which many are expressed in the placenta. In this study we used in situ hybridization and real-time PCR to study the gene expression of monoamine transporters, such as NET, SERT, VMAT2, EMT and OCT1/2, in normal

Mv routing and capacity building in disruption tolerant networks

by Brendan Burns, Oliver Brock, Brian Neil Levine, Brendan Burns, Oliver Brock, Brian Neil Levine - In Proceedings of IEEE INFOCOM , 2005
"... Disruption Tolerant Networks (DTNs) require routing algo-rithms that are different from those designed for ad hoc networks. In DTNs, transport of data through the network is achieved through the physical movement of the participants in the net-work. We address two fundamental problems of routing in ..."
