Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A novel and faster quantum-inspired algorithm for solving linear systems
线性系统 新颖 量子衍生算法
2023/4/17
In this talk, we introduce a modified classical algorithm to solve linear systems in a model that resembles the QRAM used by quantum linear solvers. Specifically, we demonstrate that for the linear sy...
Baltic herring larvae appear earlier and grow faster due to climate change

According to a recent research, both developmental stages in Baltic herring larvae, small and large, have shifted their timing to earlier dates.
Greenland is on track to lose ice faster this century than in any other over the past 12,000 years（图）
Greenland lose ice faster century past 12,000 years
2020/10/10
Greenland's rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes.The U.S. National Science Foundation-supported researc...
Sunlight degrades polystyrene faster than expected（图）
Sunlight polystyrene faster expected
2019/10/22
New research published by scientists at the Woods Hole Oceanographic Institution shows that polystyrene, one of the world's most ubiquitous plastics, may degrade in decades or centuries when exposed t...

2017/12/18
The world of an atom is one of random chaos and heat. At room temperatures, a cloud of atoms is a frenzied mess, with atoms zipping past each other and colliding, constantly changing their direction ...

Green Algae Hold Clues Engineering Faster-Growing Crops
2017/10/24
Two new studies of green algae — the scourge of swimming pool owners and freshwater ponds — have revealed new insights into how these organisms siphon carbon dioxide from the air for use in photosynth...

Climate grind mountains faster can be rebuilt
2015/12/7
Researchers for the first time have attempted to measure all the material leaving and entering a mountain range over millions of years and discovered that glacial erosion can, under the right circumst...
Better, faster, stronger: Evolving Geobacter species for enhanced capabilities
Biological sciences Geobacter Electron transfer
2015/1/28
The bacterial family of Geobacteraceae is comprised of many members including both Geobacter and Pelobacterspecies. The Geobacteraceae are the predominant Fe(III) reducing organisms in the subsurface ...
Study finds extreme temperature anomalies are warming faster than Earth's average
extreme temperature anomalies warming faster Earth's average
2014/12/30
BLOOMINGTON, Ind. -- It’s widely known that the Earth’s average temperature has been rising. But research by an Indiana University geographer and colleagues finds that spatial patterns of extreme temp...
FAMOUS, faster: using parallel computing techniques to accelerate the FAMOUS/HadCM3 climate model with a focus on the radiative transfer algorithm
FAMOUS faster parallel computing techniques accelerate the FAMOUS/HadCM3 climate model radiative transfer algorithm
2014/12/9
We have optimised the atmospheric radiation algorithm of the FAMOUS climate model on several hardware platforms. The optimisation involved translating the Fortran code to C and restructuring the algor...
Oceans may be acidifying faster today than in the past 300 million years
Oceans 300 million years
2014/9/12
With increasing levels of carbon dioxide accumulating in the atmosphere and moving into marine ecosystems, the world's oceans are becoming more acidic.
A non-robotic device that helps stroke survivors regain upper limb movement is expected to be commercially available in Australia within the next 12 months.
Linear independence of time-frequency translates of functions with faster than exponential decay
Gabor system exponential decay HRT conjecture linear independence timefrequency translates analytic zero divisor conjecture
2012/6/29
We establish the linear independence of time-frequency translates for functions $f$ having one sided decay $\lim_{x\to \infty} |f(x)| e^{cx \log x} = 0$ for all $c>0$. We also prove such results for f...

Faster than Nyquist but Slower Information Theory
2012/4/23
This paper presents a significant modification to the Random Demodulator (RD) of Tropp et al. for sub-Nyquist sampling of frequency-sparse signals. The modification, termed constrained random demodula...
Hubble's law and faster than light expansion speeds
Hubble's law light expansion speeds four-velocity vector
2011/8/18
Abstract: Naively applying Hubble's law to a sufficiently distant object gives a receding velocity larger than the speed of light. By discussing a very similar situation in special relativity, we argu...
