Agouti C57BL/6N embryonic stem cells for mouse genetic resources. [PDF]

open access: yes, 2009
We report the characterization of a highly germline competent C57BL/6N mouse embryonic stem cell line, JM8. To simplify breeding schemes, the dominant agouti coat color gene was restored in JM8 cells by targeted repair of the C57BL/6 nonagouti mutation ...

Influence des changements d’utilisation des terres sur les débits du bassin versant du Massili à Gonsé (Burkina Faso)

open access: yesVertigO, 2023
This study aims to determine the contribution of land use changes on runoff in the Massili basin in Gonsé. The study methodology is based on the analysis of the temporal variability of rainfall (1975-2019) and discharge (1975-2019) and the diachronic ...

Construction Procurement: Modelling Bidders’ Learning in Recurrent Bidding [PDF]

open access: yes, 2015
Construction remains a significant area of public expenditure. An understanding of the process of changes in construction pricing, and how the process can be manipulated through the release of bidding feedback information is vital, in order to best ...

Caractérisation de la variabilité temporelle récente des précipitations annuelles au Sénégal (Afrique de l'Ouest)

open access: yesPhysio-Géo, 2014
The wet years of the 1990s have reduced the extent of the area affected by drought. But studies have shown that the rainfall deficit persisted in the Sahelian regions until the end of the 1990s. P. OZER et al., in 2003, thought that the continuity of the

Quantifying Intra-Catchment Streamflow Processes and Response to Climate Change within a Climatic Transitional Zone: A Case Study of Buffalo Catchment, Eastern Cape, South Africa

open access: yesMathematics, 2022
The complexity of streamflow processes inhibits significant information about catchment performance and its sensitivity to climate change. Little is known about the severity of climate change within the coastal area of the monsoon–subtropical zone of ...

Exploring Photometric Redshifts as an Optimization Problem: An Ensemble MCMC and Simulated Annealing-Driven Template-Fitting Approach [PDF]

open access: yes, 2015
Using a grid of $\sim 2$ million elements ($\Delta z = 0.005$) adapted from COSMOS photometric redshift (photo-z) searches, we investigate the general properties of template-based photo-z likelihood surfaces.

Spatial and temporal characteristics of extreme precipitation in Ganjiang River Basin in the past 50 years

open access: yes暴雨灾害, 2020
The annual maximum (AM) and peak over threshold (POT) series were used to estimate the spatial and temporal characteristics of extreme precipitation over the past 50 years in Ganjiang River Basin based on the daily precipitation data from 13 hydrometric ...

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Classification using distance nearest neighbours [PDF]

open access: yes, 2010
This paper proposes a new probabilistic classification algorithm using a Markov random field approach. The joint distribution of class labels is explicitly modelled using the distances between feature vectors.
