近日，地球物理著名期刊《Geophysical Research Letters》刊发了我校地空学院袁悦锋博士后、朱培民教授和肖龙教授，联合长江大学、宁波财经大学合作者的研究成果——New constraints on the young lava flow profile in the northern Mare Imbrium。该研究通过重新分析嫦娥三号低频雷达浅层数据，推测出月球雨海北部年轻...
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...
New constraints for site-effect characterization from seismic noise analysis in southern Italy. San Fele case study
Ambient noise Shear wave velocity profile Array measurements Seimic hazard
2015/8/28
In the framework of ground-motion amplification analysis for southern Italy, the main target of this study is to provide new constraints on one-dimensional, shallow-velocity profiles for a site in the...
New constraints on dike injection and fault slip during the 1975–1984 Krafla rift crisis, NE Iceland
New constraints dike injection fault slip Krafla rift crisis, NE Iceland
2014/4/15
Correlation of KH9 spy and SPOT5 satellite images, airphotos, digital elevation model differencing, electronic distance measurement, and leveling survey data is used to constrain the deformation resul...
Features in the primordial spectrum: new constraints from WMAP7+ACT data and prospects for Planck
Features primordial spectrum constraints WMAP7+ACT data prospects Planck
2011/10/19
We update the constraints on possible features in the primordial inflationary density perturbation spectrum by using the latest data from the WMAP7 and ACT Cosmic Microwave Background experiments. The...
Accurate Measurement in the Field of the Earth of the General-Relativistic Precession of the LAGEOS II Pericenter and New Constraints on Non-Newtonian Gravity
General-Relativistic Pericenter Constraints on Non-Newtonian Gravity
2011/9/14
The pericenter shift of a binary system represents a suitable observable to test for possible deviations from the Newtonian inverse–square law in favor of new weak interactions between macroscopic obj...
New Constraints from Pb-Evaporation Zircon Ages of the Méiganga Amphibole-Biotite Gneiss, Central Cameroon, on Proterozoic Crustal Evolution
Metasediment 207Pb/206Pb Ages Crustal Evolution
2013/3/6
The amphibole biotite gneiss (ABGn) in the Méiganga area forms part of a meta volcano-sedimentary sequence of the Adamawa Yade domain (AYD), Central African Fold Belt (CAFB). This sequence shows affin...
Reassessing The Fundamentals: New Constraints on the Evolution, Ages and Masses of Neutron Stars
neutron —pulsars general —X-rays binaries —stars statistics
2011/3/25
The ages and masses of neutron stars (NSs) are two fundamental threads that make pulsars accessible to other sub-disciplines of astronomy and physics. A realistic and accurate determination of these t...
Comment on "New constraints of a light CP-odd Higgs boson and related NMSSM Ideal Higgs Scenarios" by Dermisek and Gunion (arXiv:1002.1971 [hep-ph])
light CP-odd Higgs boson NMSSM Ideal Higgs
2010/3/16
In two recent papers (arXiv:1002.1971 [hep-ph] and arXiv:0911.2460 [hep-ph]) Dermisek and Gunion provide new constraints on a light CP-odd Higgs boson in the framework of the NMSSM (or similar models)...
New Constraints on the Primordial Magnetic Field
primordial magnetic field numerical analysis
2010/3/19
We present the newest statistical and numerical analysis of the matter and cosmic microwave background power spectrum with effects of the primordial magnetic field (PMF) included. New limits to the PM...
Airborne observations of total RONO2: new constraints on the yield and lifetime of isoprene nitrates
Airborne observations yield lifetime isoprene nitrates
2009/3/13
Formation of isoprene nitrates (INs) is an important free radical chain termination step ending production of ozone and possibly affecting formation of secondary organic aerosol. Isoprene nitrates als...
New constraints on the gas age-ice age difference along the EPICA ice cores, 0–50 kyr
age-ice EPICA ice cores
2008/11/5
Gas is trapped in polar ice sheets at ~50–120 m below the surface and is therefore younger than the surrounding ice. Firn densification models are used to evaluate this ice age-gas age difference (Δag...
In this paper, we propose a feasible QP-free
method for solving nonlinear inequality
constrained optimization problems. A new working set is proposed
to estimate the active set. Specially, to deter...
