The mass of the young planet Pictoris b through the astrometric motion of its host star [PDF]

open access: yes, 2018
The young massive Jupiters discovered with high-contrast imaging provide a unique opportunity to study the formation and early evolution of gas giant planets.

Leveraging rules on integrated 3D semantic city models for validating scenarios of urban evolution

open access: yesData-Centric Engineering
The process to better understand the intricate evolution of our urban territories requires combining urban data from different or concurrent instances of time to provide stakeholders with more complete views of possible evolutions of a city.

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Quiescent thermal emission from neutron stars in LMXBs [PDF]

open access: yes, 2015
We monitored the quiescent thermal emission from neutron stars in low-mass X-ray binaries after active periods of intense activity in x-rays (outbursts).

Hydrological responses of a watershed to historical land use evolution and future land use scenarios under climate change conditions [PDF]

open access: yesHydrology and Earth System Sciences, 2008
Watershed runoff is closely related to land use but this influence is difficult to quantify. This study focused on the Chaudière River watershed (Québec, Canada) and had two objectives: (i) to quantify the influence of historical agricultural land use ...

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

open access: yesMolecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

Tracing the Scenarios in Scenario-Based Product Design: a study to support scenario generation [PDF]

open access: yes, 2007
Scenario-based design originates from the human-computer interaction and\ud software engineering disciplines, and continues to be adapted for product development.

Cyclic cosmology from Lagrange-multiplier modified gravity

open access: yes, 2011
We investigate cyclic and singularity-free evolutions in a universe governed by Lagrange-multiplier modified gravity, either in scalar-field cosmology, as well as in $f(R)$ one.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Spectral evolution of two-layer weak geostrophic turbulence. Part I: Typical scenarios [PDF]

open access: yesNonlinear Processes in Geophysics, 1996
Long-time evolution of large-scale geophysical flows is considered in a β-plane approximation. Motions in an infinite 2-layer model ocean are treated as a system of weakly nonlinear Rossby waves (weak geostrophic turbulence). The evolution
