Fragmentation functions in nuclear media
(American Physical Society, 2010-03)
We perform a detailed phenomenological analysis of how well hadronization in nuclear environments can be described in terms of effective fragmentation functions. The medium modified fragmentation functions are assumed to ...
Relative effects of fragment size and connectivity on bird community in the Atlantic Rain Forest: Implications for conservation
(ELSEVIER SCI LTD, 2008)
It is known that large fragment sizes and high connectivity levels are key components for maintaining species in fragments; however, their relative effects are poorly understood, especially in tropical areas. In order to ...
Beauty before age: landscape factors influence bird functional diversity in naturally regenerating fragments, but regeneration age does not
Effective ecological restoration actions should be able to recover ecosystem processes that influence community development in the long term. However, there is scarce information on how landscape factors promote or accelerate ...
Role of heavy quarks in light hadron fragmentation
(American Physical Society, 2016-08)
We investigate the role of heavy quarks in the production of light flavored hadrons and in the determination of the corresponding nonperturbative hadronization probabilities. We define a general mass variable flavor number ...
Fragmentation drives tropical forest fragments to early successional states: A modelling study for Brazilian Atlantic forests
(ELSEVIER SCIENCE BV, 2011)
Land use leads to massive habitat destruction and fragmentation in tropical forests. Despite its global dimensions the effects of fragmentation on ecosystem dynamics are not well understood due to the complexity of the ...
Global analysis of fragmentation functions for eta mesons
(American Physical Society, 2011-02)
Fragmentation functions for eta mesons are extracted at next-to-leading order accuracy of QCD in a global analysis of data taken in electron-positron annihilation and proton-proton scattering experiments. The obtained ...
Pattern of tree species diversity in riparian forest fragments of different widths (SE Brazil)
(Kluwer Academic PublDordrechtHolanda, 1997)
Uncertainties in pion and kaon fragmentation functions
(American Physical Society, 2012-10)
We present a detailed assessment of uncertainties in parton-to-pion and parton-to-kaon fragmentation functions obtained in recent global QCD analyses of single-inclusive hadron production data at next-to-leading order ...
Fragment size, vegetation structure and physical environment control grassland functioning: a test based on artificial neural networks
Questions: How do fragment-level characteristics affect remnant grassland functioning in a highly transformed landscape? Are artificial neural networks (ANNs) a better statistical tool to model variations in grassland ...
Parton-to-kaon fragmentation revisited
(American Physical Society, 2017-05)
We revisit the global QCD analysis of parton-to-kaon fragmentation functions at next-to-leading-order accuracy using the latest experimental information on single-inclusive kaon production in electron-positron annihilation, ...
