Resumen
The transport of intensity equation (TIE) is the basis of a powerful non-interferometric technique for phase retrieval. When intensity gradients are present, the generalized belief is that the solution of the TIE (i.e. the phase distribution) can be found by solving two Poisson equations. In the present paper we will demonstrate that this expression for the TIE solution holds when intensity and phase gradients are parallel (or null), but in general the usually accepted solution is not correct. We perform simulations with arbitrary intensity and phase functions in order to show the phase errors derived from the use of this expression.

Moreno-Gomez, S.",,"2006",,"As a result of the revision of taxonomic publications, herbaria specimens (IBUG, IEB, MEXU y ZEA), and field work (800 specimens collected), we register 92 families, 285 genera, and 550 tree species in the State of Colima. The families with more genera and species are Fabaceae (42 and 115, respectively), Euphorbiaceae (19 and 36), and Rubiaceae (13 and 23). The richest genera are Quercus (22), Bursera (19), Ficus (12), Lonchocarpus (11), and Senna (11). We found that only 3 species are endemic of Colima and 22 species are shared only with another state (21 with Jalisco and one with Michoacan). A total of 43.4% species are endemic to Mexico and 40.2% are widely distributed. 56.6% of the species are located in only one vegetation type. Tropical deciduous forest had the largest percentage of restricted species (37.7%) and richness (68.8%). A total of 33 species are included in some risk category. The Sierra Manantlan Biosphere Reserve, located in Colima and Jalisco, harbours 64% of tree species found in our study. Specific recommendations are given for the development of floristic studies, and tree flora conservation efforts in Colima.",,,,,,,,,"http://hdl.handle.net/20.500.12104/45472","http://www.scopus.com/inward/record.url?eid=2-s2.0-77951853016&partnerID=40&md5=692cc466faeca0ddc65efe599ecc7255",,,,,,"2",,"Revista Mexicana de Biodiversidad",,"271 295",,"77",,"Scopus",,,,,,"Cloud forest; Conservation; Endemism; Oak forest; Risk categories; Trees; Tropical dry forest; Vegetation types",,,,,,"Tree flora richness and biogeography of the State of Colima, Mexico [Riqueza y biogeografía de la flora arbárea del estado de Colima, México]",,"Article"

Dobrovinskaya, O.R.",,"2008",,"In this study, we present patch-clamp characterization of the background potassium current in human lymphoma (Jurkat cells), generated by voltage-independent 16 pS channels with a high (?100-fold) K +/Na+ selectivity. Depending on the background K + channels density, from few per cell up to ?1 open channel per ?m2, resting membrane potential was in the range of -40 to -83 mV, approaching E K = -88 mV. The background K+ channels were insensitive to margotoxin (3 nM), apamine (3 nM), and clotrimazole (1 ?M), high-affinity blockers of the lymphocyte Kv1.3, SKCa2, and IKCa1 channels. The current depended weakly on external pH. Arachidonic acid (20 ?M) and Hg 2+ (0.3-10 ?M) suppressed background K+ current in Jurkat cells by 75-90%. Background K+ current was weakly sensitive to TEA+ (IC50 = 14 mM), and was efficiently suppressed by externally applied bupivacaine (IC50 = 5 ?M), quinine (IC 50 = 16 ?M), and Ba2+ (2 mM). Our data, in particular strong inhibition by mercuric ions, suggest that background K+ currents expressed in Jurkat cells are mediated by TWIK-related spinal cord K+ (TRESK) channels belonging to the double-pore domain K+ channel family. The presence of human TRESK in the membrane protein fraction was confirmed by Western blot analysis. " 2008 Springer-Verlag.
