Vegetation growth in Northern Hemisphere stunted by water constraints in warming climate
warming climate water constraints vegetation growth greenhouse gass
2021/8/4
A new study of vegetation growth in the Northern Hemisphere over the past 30 years has found that vegetation is becoming increasingly water-limited as global temperatures increase, which has the poten...

MESH MODELLING OF 3D POINT CLOUD FROM UAV IMAGES BY POINT CLASSIFICATION AND GEOMETRIC CONSTRAINTS
Surface Reconstruction Surface Normal Point cloud Mesh model
2018/6/4
The point cloud generated by multiple image matching is classified as an unstructured point cloud because it is not regularly point spaced and has multiple viewpoints. The surface reconstruction techn...
Two Types of Granites in the Western Yangtze Block and Their Implications for Regional Tectonic Evolution: Constraints from Geochemistry and Isotopic Data
I-type granite S-type granite geochemistry petrogenesis tectonic setting Western Yangtze Block
2018/4/10
In the western Yangtze Block, widespread Mesoproterozoic to Neoproterozoic rocks are the key to understanding the Precambrian tectonic-magmatic evolution of the region. However, their petrogenesis and...
Constraints on mechanisms of chondrule formation from chondrule precursors and chronology of transient heating events in the protoplanetary disk
chondrules refractory inclusions chondrule precursors transient heating
2017/4/10
The mineralogy, petrography, and oxygen-isotope compositions of porphyritic chondrules—dominant chondrule type
in most chondrite groups—suggest formation by incomplete melting of isotopically diverse...
The I-Xe chronometer and its constraints on the accretion and evolution of planetesimals
extinct radioisotopes iodine-xenon chondrites early solar system chronology
2017/4/10
We report a –1.6 ± 2.6 Myr (1s error) I-Xe age of the ungrouped achondrite NWA 7325 relative to the Shallowater
standard. We re-evaluate the calibration of the relative I-Xe dating system against the...
New constraints on shergottite petrogenesis from analysis of Pb isotopic compositional space: Implications for mantle heterogeneity and crustal assimilation on Mars
shergottite Pb isotopes Martian geochemistry crustal assimilation mantle heterogeneity
2017/4/10
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have
provided clues to understanding the geochemical evolution of the Martian mantle and id...
Nonparametric and Semiparametric Regressions Subject to Monotonicity Constraints: Estimation and Forecasting
Nonlinearity Nonparametric regression Semiparametric regression Local mono- tonicity Bagging
2016/1/25
This paper considers nonparametric and semiparametric regression models subject to monotonicity constraint. We use bagging as an alternative approach to Hall and Huang (2001). Asymptotic properties of...

Energy-Efficient Power and Rate Control with QoS Constraints:A Game-Theoretic Approach
Energy-Efficient Power Rate Control QoS Constraints Game-Theoretic Approach
2015/9/29
A game-theoretic model is proposed to study the cross-layer problem of joint power and rate control with quality of service (QoS) constraints in multiple-access networks. In the proposed game, each us...
