Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Simultaneous Optimal Transport
优化运输 矢量值度量 Wasserstein距离概念
2023/4/14
We propose a general framework of mass transport between vector-valued measures, which will be called simultaneous mass transport. The new framework is motivated by the need to transport resources of ...
Today, at the Moriond conference, the ATLAS and CMS collaborations have both presented the observation of a very rare process: the simultaneous production of four top quarks. They were observed using ...
Mass extinction of land and sea biodiversity 250 million years ago not simultaneous（图）
Mass extinction land sea biodiversity 250 million years ago simultaneous
2019/12/13
Some 250 million years ago, simultaneous mass extinctions of marine and terrestrial life occurred in an event known as the End-Permian. Or so scientists believed.New research led by Colby College geol...
Ultrasonic wave extraction and simultaneous analysis of polycyclic aromatic hydrocarbons (PAHs) and phthalic esters in soil
Polycyclic aromatic hydrocarbons Phthalic Acid Esters Ultrasonic assistant extraction technique
2018/3/23
A method is developed for detection of polycyclic aromatic hydrocarbons (PAHs) and Phthalic Acid Esters (PAEs) in soil samples. Ultrasonic Wave Extraction under airtight circumstances is adopted to ex...
Simultaneous determination of 58 major and trace elements in volcanic glass shards from the INTAV sample mount using femtosecond laser ablation-inductively coupled plasma-mass spectrometry
volcanic glass tephra LA-ICP-MS element abundance femtosecond lasert
2017/4/10
Four volcanic glass samples on the INternational focus group on Tephrochronology And Volcanism (INTAV) sample
mount described by Kuehn et al. (2011) were analyzed to establish a new methodology for m...
ON SIMULTANEOUS LINEARIZATION OF DIFFEOMORPHISMS OF THE SPHERE
DIFFEOMORPHISMS SIMULTANEOUS LINEARIZATION
2015/9/29
Let R1, R2 . . . Rm be rotations generating SOd+1, d ≥
2, and f1, f2 . . . fm be their small smooth perturbations. We show
that {fα} can be simultaneously linearized if and only if the assocated ran...
Simultaneous ionospheric E- and F-layer perturbations caused by some major earthquakes in India
ionosphere E- and F-layers earthquakes-magnetic storm foF2 and foEs
2015/9/2
The variation in nighttime ionospheric E- and F-region critical frequencies (foEs and foF2) is examined for the months of August 1988, September 1993 and May 1997 in which major earthquakes (6
Selection and Estimation for Large-Scale Simultaneous Inference
Large-Scale Simultaneous Inference Selection
2015/8/20
Modern scientific technology is providing a new class of simultaneous inference
problems for the applied statistician, where there are hundreds or thousands or even
more hypothesis tests to co...
Large-Scale Simultaneous Hypothesis Testing: The Choice of a Null Hypothesis
Null Hypothesis Simultaneous Hypothesis Testing
2015/8/20
Current scientific techniques in genomics and image processing routinely produce hypothesis testing problems with hundreds or thousands of cases to consider simultaneously.
This poses new di...
Simultaneous Inference: When Should Hypothesis Testing Problems Be Combined?
Simultaneous Inference Testing Problems
2015/8/20
Modern statisticians are often presented with hundreds or thousands of hypothesis
testing problems to evaluate at the same time, generated from new scientific technologies such as microarrays, ...
Structured and simultaneous Lyapunov functions for system stability problems
Lyapunov function system robustness quadratic lyapunov function the numerical values
2015/8/13
It is shown that many system stability and robustness problems can be reduced to the question of when there is a quadratic Lyapunov function of a certain structure which establishes stability of dx/dt...
Policies for simultaneous estimation and optimization
Policy uncertainty systems linear systems secondary costs system parameters the gaussian distribution the impulse response system
2015/8/11
Policies for the joint identification and control of uncertain systems are presented. The discussion focuses on the case of a multiple input, single output linear system, with no dynamics and quadrati...
Simultaneous Imaging of Phytoplankton and Zooplankton Distributions
Phytoplankton Zooplankton Distributions
2015/8/6
Understanding the dynamics of the relationship between phytoplankton and higher trophic levels is necessary for understanding the transfers of matter and energy through planktonic food webs. There hav...
Nitrogen Removal from Milking Center Wastewater via Simultaneous Nitrification and Denitrification Using a Biofilm Filtration Reactor
Nitrogen Loading Rate Simultaneous Nitrification and Denitrification
2016/5/18
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which should be separately managed from livestock manure due to the negative impacts of manure nutrients a...
Simultaneous determinations of fluorine, chlorine, and sulfur in rock samples by ion chromatography combined with pyrohydrolysis
pyrohydrolysis halogen sulfur ion chromatography geological reference material
2017/4/10
We present a simplified method for simultaneous determinations of fluorine (F), chlorine (Cl), and sulfur (S) contents
and isotopic abundances in rock samples. After using pyrohydrolysis to extract F...
