Network growth for enhanced natural selection [PDF]

Physical Review E, 2009
Natural selection and random drift are competing phenomena for explaining the evolution of populations. Combining a highly fit mutant with a population structure that improves the odds that the mutant spreads through the whole population tips the balance in favor of natural selection.

Automatic tree crown segmentation using dense forest point clouds from Personal Laser Scanning (PLS)

International Journal of Applied Earth Observations and Geoinformation, 2022
Among digital-based technologies to monitor forest ecosystems, personal laser scanning (PLS) has high potential to characterize even complex deciduous and rainforests.

Natural Resource Abundance and Economic Growth [PDF]

SSRN Electronic Journal, 2004
This paper explores whether natural resource abundance leads, other things equal, to slower growth rates. We distinguish between natural resource dependence (RD) and the natural resource endowment (RE). We estimate three models, using World Bank data on national capital stocks.

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Natural Resources, Economic Growth and Geography [PDF]

SSRN Electronic Journal, 2018
Worldwide materials extraction increased by a factor of 8.4 over the course of the 20th century. In the meantime, global GDP and population increased by factors of about 22 and 4, respectively. This reveals that one of the key factors driving the increase in the exploitation of the resources was the growth in world population, although mitigated by the

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Les évolutions démographiques 1999-2007 de la France métropolitaine : continuités ou ruptures ?

Espace populations sociétés, 2011
Since 2004, France adopted a new census method. So, comparing the population of France in 1999 and in 2007 is not pertinent because the figures were calculated according to different census methods.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

THE GROWTH AFTERMATH OF NATURAL DISASTERS [PDF]

Journal of Applied Econometrics, 2011
SUMMARYThis paper traces the yearly response of gross domestic product growth—both aggregated and disaggregated into its agricultural and non‐agricultural components—to four types of natural disasters: droughts, floods, earthquakes, and storms. The paper uses a methodological approach based on pooling the experiences of various countries over time.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
