(Ecological Soc. Amer., 2015)One of the fastest growing uses of stable isotope analysis in ecology is using hydrogen isotope (delta H-2) values to characterize animal movement and migration strategies. Most studies measure delta H-2 values in metabolically ...

(Ecological Society of America, 2015)© 2015 Newsome et al. One of the fastest growing uses of stable isotope analysis in ecology is using hydrogen isotope (δ2H) values to characterize animal movement and migration strategies. Most studies measure δ2H values ...
-
(Amer Physical Soc, 2016)The particle-particle interaction potential of an N-atom cluster is expanded in n-body contributions. The expansion allows us to determine the magnitude of each one of the n-body terms, and consequently quantifies how ...
-
(Elsevier Science SA, 2018)This review focuses on the recent developments of unsymmetrically-substituted multidentate Schiff bases whose steric and electronic characteristics are easily manipulated by selecting suitable condensing aldehydes or ketones ...
-
(Elsevier, 2017)The 2001 Mw7.7 Bhuj mainshock seismic sequence in the Kachchh area, occurring during 2001 to 2012, has been analyzed using mono-fractal and multi-fractal dimension spectrum analysis technique. This region was characterized ...
-
(MDPI, 2021)This paper explores the spatial variations of the statistical scaling features of low to high latitude geomagnetic field fluctuations at Swarm altitude. The data for this study comes from the vector field magnetometer ...
-
(BioMed Central, 2015)Background: Pseudomonas aeruginosa is known to be a multidrug resistant opportunistic pathogen. Particularly, P. aeruginosa PAO1 polyphosphate kinase mutant (ppk1) is deficient in motility, quorum sensing, biofilm formation ...
-
(Nature Publishing Group, 2017)Fragile-X syndrome (FXS) patients display intellectual disability and autism spectrum disorder due to silencing of the X-linked, fragile-X mental retardation-1 (FMR1) gene. Dysregulation of cAMP metabolism is a consistent ...
-
(Wiley, 2020)Aim Antarctica's remote and extreme terrestrial environments are inhabited by only two species of native vascular plants. We assessed genetic connectivity amongst Antarctic and South American populations of one of these ...
-
(Nature, 2015)Within the volcanological community there is a growing awareness that many large-to smallscale, point-source eruptive events can be fed by multiple melt bodies rather than from a single magma reservoir. In this study, glass ...
-
(National Academy of Sciences, 2018)Bacterial endosymbionts that provide nutrients to hosts often have genomes that are extremely stable in structure and gene content. In contrast, the genome of the endosymbiont Hodgkinia cicadicola has fractured into multiple ...
-
(American Institute of Mathematical Sciences, 2019)Small non-autonomous perturbations around an equilibrium of a nonlinear delayed system are studied. Under appropriate assumptions, it is shown that the number of T-periodic solutions lying inside a bounded domain Ω ⊂ R N ...
-
(Elsevier B.V., 2017)© 2017 Elsevier B.V. A large variety of antipredator defenses are exhibited by plants, animals and microbes in nature. A deep understanding of the dynamic consequences of prey responses to predation risk is essential for ...
-
(2009-09-14)We study the dynamics of a pair of nonlinear split-ring resonators (a ‘metadimer’) excited by an alternating magnetic field and coupled magnetically. Linear metadimers of this kind have been recently used as the elementary ...

(Centro de Perfeccionamiento, Experimentación e Investigaciones Pedagógicas, 1976-08)
-
(WILEY-V C H VERLAG GMBH, 2006-01-30)Side-chain-oxidized C-28-sterol 1 and one new pregnane metabolite 2 were isolated from eastern Pacific Muricea spp. The C-24(28)-epoxide functionality is a key intermediate in the C-24-dealkylation mechanism of the conversion ...
-
(Elsevier B.V., 2017)© 2017 Elsevier B.V. FtsZ filaments localize at the middle of the bacterial cell and participate in the formation of a contractile ring responsible for cell division. Previous studies demonstrated that the highly conserved ...
-
(American Society for Microbiology, 2014)© 2014 Prados-Rosales et al.Pathogenic and nonpathogenic species of bacteria and fungi release membrane vesicles (MV), containing proteins, polysaccharides, and lipids, into the extracellular milieu. Previously, we ...
-
(W.B. Saunders, 2011)Background & Aims: Gut-associated dendritic cells (DC) metabolize vitamin A into all-trans retinoic acid (RA), which is required to induce lymphocytes to localize to the gastrointestinal tract and promotes the differentiation ...
-
(2012)GLUT4-containing vesicles cycle between the plasma membrane and intracellular compartments. Insulin promotes GLUT4 exocytosis by regulating GLUT4 vesicle arrival at the cell periphery and its subsequent tethering, docking, ...
