Measurements of 810 nm transmittance changes in leaves, simultaneously with Chl fluorescence, CO(2) uptake and O(2) evolution, were carried out on potato (Solanum tuberosum L.) leaves with altered expression of plastidic NADP-dependent malate dehydrogenase. Electron transport rates were calculated: J(C) from the CO(2) uptake rate considering ribulose-1,5-bisphosphate (RuBP) carboxylation and ox...

Photosystem I (PSI) is a pigment-protein complex located in the thylakoid membrane of cyanobacteria and chloroplasts of algae and higher plants, which functions as a plastocyanin (or cytochrome c6)-ferredoxin oxidoreductase. The reducing potential of ferredoxin is utilized for a variety of biochemical processes such as the reduction of NADP, or the assimilation of nitrate or sulfate. In higher ...

The generation of transmembrane ion gradients by Oxalobacter formigenes cells metabolizing oxalate was studied. The magnitudes of both the transmembrane electrical potential (delta psi) and the pH gradient (internal alkaline) decreased with increasing external pH; quantitatively, the delta psi was the most important component of the proton motive force. As the extracellular pH of metabolizing c...

For a nonincreasing function $\psi$, let $\textrm{Exact}(\psi)$ be the set of complex numbers that are approximable by rational to order $\psi$ but no better order. In this paper, we obtain Hausdorff dimension and packing when $\psi(x)=o(x^{-2})$. We also prove lower bound is greater than $2-\tau/(1-2\tau)$ $\tau=\limsup_{x\to\infty}\psi(x)x^2$ small enough.

Working in the nonrelativistic-QCD factorization framework at next-to-leading order ${\ensuremath{\alpha}}_{s}$, we fit relevant color octet long-distance matrix elements of $\ensuremath{\psi}(2S)$ meson, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{1}S}_{0}^{[8]})⟩$, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}S}_{1}^{[8]})⟩$, and $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}P}_{0}^{[8]})⟩$, to...

Root hydraulic conductivity (L(p)) and leaf osmotic potential at full turgor (Psi(pi,o)) were measured in young, drought-stressed and nonstressed peach (Prunus persica (L.) Batsch), olive (Olea europaea L.), citrumelo (Poncirus trifoliata Raf. x Citrus paradisi Macf.) and pistachio (Pistachia integerrima L.). Drought stress caused a 2.5- to 4.2-fold reduction in L(p), depending on species, but ...

Recent studies suggest that the degree of mitochondrial dysfunction in cerebral ischemia may be an important determinant of the final extent of tissue injury. Although loss of mitochondrial membrane potential (psi(m)), one index of mitochondrial dysfunction, has been documented in neurons exposed to ischemic conditions, it is not yet known whether astrocytes, which are relatively resistant to i...

Private set intersection (PSI) has a wide range of applications such as privacy-preserving data mining. With the advent of cloud computing it is now desirable to take advantage of the storage and computation capabilities of the cloud to outsource datasets and delegate PSI computation. In this paper we design OPSI, a protocol for delegated private set intersection on outsourced datasets based on...

Working in the nonrelativistic-QCD factorization framework at next-to-leading order ${\ensuremath{\alpha}}_{s}$, we fit relevant color octet long-distance matrix elements of $\ensuremath{\psi}(2S)$ meson, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{1}S}_{0}^{[8]})⟩$, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}S}_{1}^{[8]})⟩$, and $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}P}_{0}^{[8]})⟩$, to...
