An approach version of fuzzy metric spaces including an ad hoc fixed point theorem
(Springer, 2015-02-27)
In this paper, inspired by two very different, successful metric theories such us the real view-point of Lowen's approach spaces and the probabilistic field of Kramosil and Michalek's fuzzymetric spaces, we present a family ...
Mass spectrometry coupled to imaging techniques: The better the view the greater the challenge
(Frontiers Research Foundation, 2015-01-21)
These are definitively exciting times for membrane lipid researchers. Once considered just as the cell membrane building blocks, the important role these lipids play is steadily being acknowledged. The improvement occurred ...
Income tax progressivity, growth, income inequality and welfare
(Springer, 2015-03)
This paper analyzes the effects of personal income tax progressivity on long-run economic growth, income inequality and social welfare. The quantitative implications of income tax progressivity increments are illustrated ...
On the Stability and Equilibrium Points of Multistaged SI (n) R Epidemic Models
(Hindawi Publishing, 2015)
This paper relies on the concept of next generation matrix defined ad hoc for a new proposed extended SEIR model referred to as SI(n)R-model to study its stability. The model includes n successive stages of infectious ...
Photosynthetic responses of trees in high-elevation forests: comparing evergreen species along an elevation gradient in the Central Andes
(Oxford University Press, 2015)
Plant growth at extremely high elevations is constrained by high daily thermal amplitude, strong solar radiation and water scarcity. These conditions are particularly harsh in the tropics, where the highest elevation ...
Looking at the Camp: Paleolithic Depiction ofa Hunter-Gatherer Campsite
(Public Library Science, 2015-12-02)
Landscapes and features of the everyday world were scarcely represented in Paleolithic art, especially those features associated with the human landscape (huts and campsites). On the contrary, other figurative motifs ...
Insight on how fishing bats discern prey and adjust their mechanic and sensorial features during the attack sequence
(Nature Publishing Group, 2015-07-21)
Several insectivorous bats have included fish in their diet, yet little is known about the processes underlying this trophic shift. We performed three field experiments with wild fishing bats to address how they manage to ...
Can environmental constraints determine random patterns of plant species co-occurrence?
(Wiley Blackwell, 2015-03)
Plant community ecologists use the null model approach to infer assembly processes from observed patterns of species co-occurrence. In about a third of published studies, the null hypothesis of random assembly cannot be ...
Iron-Catalyzed Direct α-Arylation of Ethers with Azoles
(Royal Society of Chemistry, 2015-07-14)
The direct α-arylation of cyclic and acyclic ethers with azoles has been achieved, which features a novel iron-catalyzed cross-dehydrogenative coupling (CDC) process. This practical oxidative method allowed the efficient ...
Peripheral Brain-Derived Neurotrophic Factor (BDNF) As a Biomarker in Bipolar Disorder: a Meta-Analysis of 52 Studies
(Biomed Central, 2015-11-30)
Background: The neurotrophic hypothesis postulates that mood disorders such as bipolar disorder (BD) are associated with a lower expression of brain-derived neurotrophic factor (BDNF). However, its role in peripheral blood ...
