中国科学院动物研究所专利：Recombinant broad-spectrum Metarhizium and production method and application thereof
中国科学院动物研究所 专利 broad-spectrum Metarhizium
2024/5/31
本发明提供了一种下调或不表达单胺氧化酶的重组广谱绿僵菌， 或其中色胺含量高于野生型广谱绿僵菌，重组广谱绿僵菌是菌株本身，菌株后代，菌株产生的分生孢子，菌株产生的菌丝体或它们的任意组合。 从重组广谱绿僵菌中敲除单胺氧化酶基因，显著提高了绿僵菌中色胺的浓度， 从而显著提高其杀虫效率，使野生型广谱绿僵菌的半致死时间LT50从7.33±0.445天缩短到6.136±0.488天。 本发明的重组广谱绿僵菌对...

Statement on NSF and SpaceX Radio Spectrum Coordination Agreement
NSF SpaceX Radio Spectrum Coordination Agreement
2019/6/4
In late May, SpaceX launched its first 60 Starlink satellites into orbit. SpaceX plans to launch a much larger satellite constellation into low-Earth orbit with the goal of providing terrestrial inter...
COMPENSATION OF THE IONOSPHERIC EFFECTS ON SAR INTERFEROGRAM BASED ON RANGE SPLIT-SPECTRUM AND AZIMUTH OFFSET METHODS – A CASE STUDY OF YUSHU EARTHQUAKE
InSAR Ionospheric effects Range split-spectrum Azimuth offset Ionosphere correction Yushu earthquake
2018/4/30
InSAR technique can measure the surface deformation with the accuracy of centimeter-level or even millimeter and therefore has been widely used in the deformation monitoring associated with earthquake...
Electric Field Modulation of the Fluorescence Spectrum from Rhodobacter Sphaeroides Reaction Centers
fluorescence counterstain nuclear counterstain immunocytochemistry propidium iodide cell culture
2016/5/20
The fluorescence intensity from randomly oriented Rhodobacter ( Rb.) sphaeroides photosynthetic reaction centers at 77 K increases in an applied electric field. This is ascribed to a net reduction in ...
Bacterial hole puncher could be new broad-spectrum antibiotic
Bacterial hole puncher new broad-spectrum antibiotic
2015/10/27
Bacteria have many methods of adapting to resist antibiotics, but a new class of spiral polypeptides developed at the University of Illinois targets one thing no bacterium can live without: an outer m...
The spectrum of thermally stimulated currents in rock samples from KTB drilling:preliminary results
thermally stimulated depolarization currents (TSDC) KTB drilling rocks relation parameters
2015/9/28
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...

This paper deals with the research made during the COST 296 action in the WG2, WP 2.3 in the antennas and HF spectrum management fields, focusing the Mitigation of Ionospheric Effects on Radio Systems...
A signal-strength model for gravity-field spectrum components in a local space
Earth's Gravitational Potential Local Area Spectrum Structure Spherical Cap Harmonic Analysi
2015/8/26
In the Earth gravity-field model, potential coefficients are projections of the Earth gravitational potential on the corresponding spherical harmonics by degree and order. These coefficients reflect t...
Low frequency signal spectrum analysis for strong earthquakes
VLF/LF signal propagation eartquake precursors
2015/8/24
We examined changes in the spectral composition of the low frequency (LF) subionospheric signals from the NRK transmitter (37.5 kHz) in Iceland that were received in Bari (Italy) relative to the earth...
Dynamical system state need not have spectrum
Dynamic system nonlinear dynamical systems differential equation
2015/8/13
Recently there has been much study of nonlinear dynamical systems (differential equations) which have chaotic solutions. While there is not precise definition of what a chaotic solution is, it is gene...
The directional spectrum S(k) [or S(f,θ)] measures the distribution of wave energy in wave number, k, (or frequency, f) and direction. Different contributions to local wave energy, e.g., swell from di...
