Os grandes sistemas técnicos e o espaço geográfico. Revisão de posições e articulações conceituais [PDF]

, 2016
El estudio de las modernas redes de infraestructura en términos de “grandes sistemas técnicos” fue inaugurado por Hughes y desarrollado por analistas sociales de la técnica como Joerges, Mayntz y Gras.

Detecting extirpation: A localized approach to a global problem

PLANTS, PEOPLE, PLANET, EarlyView.
The global biodiversity crisis stems from a cascading series of extirpations driving species toward extinction. Addressing this crisis requires methods for early detection of extinction at local scales, where communities can mobilize conservation efforts.

Engineering compact Physalis peruviana (goldenberry) to promote its potential as a global crop

PLANTS, PEOPLE, PLANET, EarlyView.
Goldenberry (Physalis peruviana) produces sweet, nutritionally rich berries, yet like many minor crops, is cultivated in limited geographical regions and has not been a focus of breeding programs for trait enhancement. Leveraging knowledge of plant architecture‐related traits from related species, we used CRISPR/Cas9‐mediated gene editing to generate a

Radiatively inefficient accretion flows induced by gravitational-wave emission before massive black hole coalescence

, 2010
We study an accretion flow during the gravitational-wave driven evolution of binary massive black holes. After the binary orbit decays due to an interaction with a massive circumbinary disk, the binary is decoupled from the circumbinary disk because the ...

Compact massive objects in Virgo galaxies: the black hole population [PDF]

, 2008
We investigate the distribution of massive black holes (MBHs) in the Virgo cluster. Observations suggest that AGN activity is widespread in massive galaxies (M>1e10 solar masses), while at lower galaxy masses star clusters are more abundant, which might ...

Prioritizing bat roosts for conservation with a global multicriteria bat roost priority index based on community science

Conservation Biology, EarlyView.
Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

Conservation Biology, EarlyView.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...

Efficient Merger of Binary Supermassive Black Holes in Merging Galaxies

, 2011
In spherical galaxies, binary supermassive black holes (SMBHs) have difficulty reaching sub-parsec separations due to depletion of stars on orbits that intersect the massive binary - the final-parsec problem.

Low-frequency gravitational-wave science with eLISA/NGO [PDF]

, 2012
We review the expected science performance of the New Gravitational-Wave Observatory (NGO, a.k.a. eLISA), a mission under study by the European Space Agency for launch in the early 2020s. eLISA will survey the low-frequency gravitational-wave sky (from 0.
