Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Mixed-binary Convex Quadratic Optimization and Its Applications in Inference with Sparsity
二元凸 二次优化 稀疏推理
2023/4/14
Sparsity is a naturally occurring characteristic in many real-world applications including signal denoising, outlier detection, and finance. On one hand, sparsity assumption allows people to tackle in...
Astronomers discover a rare “black widow” binary, with the shortest orbit yet（图）
“黑寡妇”双星 恒星 伴星环 银河系
2023/6/9
The flashing of a nearby star has drawn MIT astronomers to a new and mysterious system 3,000 light years from Earth. The stellar oddity appears to be a new “black widow binary” — a rapidly spinning ne...
Research done at Cornell has uncovered from gravitation wave data the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and...

NSF latest LIGO-Virgo binary black hole merger
2017/12/19
Scientists supported by the National Science Foundation (NSF) recently announced the detection of the merger of two relatively "light" black holes, 7 and 12 times the mass of the sun, respectively, at...
Binary near-Earth asteroid formation:Rubble pile model of tidal disruptions
Asteroids Dynamics Rotational dynamics Tides solid body
2015/12/25
We present numerical simulations of near-Earth asteroid (NEA) tidal disruption resulting in bound, mutually orbiting systems. Using a rubble pile model we have constrained the relative likelihoods for...

Many researchers agree on the basic architecture of the "world model" where knowledge about the
world required for organization of agent's intelligent behavior is represented. However, most proposals...

Estimators for the Entropy Rate of Binary Hidden Markov Processes(英文)
Binary hidden Markov process entropy rate bound estimator,algorithm
2015/5/28
The entropy rate of a hidden Markov process (HMP) is important in theory and practical applications, but it is hard to get an analytical expression or obtain a numerical estimator. In this paper, a ne...

Robustness of an Odds-ratio Test in a Stratified Group Sequential Trial with a Binary Outcome Measure
Binary outcome Odds-ratio Stratification
2015/3/18
Many clinical trials compare two or more treatment groups by using a binary outcome measure.
For example, the goal could be to determine whether the frequency of pain episodes is
significantly reduc...
VARIABLE O VI AND N V EMISSION FROM THE X-RAY BINARY LMC X-3: HEATING OF THE BLACK HOLE COMPANION*
Cosmic Origins
2014/12/22
Based on high-resolution ultraviolet spectroscopy obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) and the Cosmic Origins Spectrograph, we present new detections of O VI and N V emissio...
THE SINGLE-DEGENERATE BINARY ORIGIN OF TYCHO'S SUPERNOVA AS TRACED BY THE STRIPPED ENVELOPE OF THE COMPANION
X-ray arc Tycho's supernova
2014/12/20
We propose that a nonthermal X-ray arc inside the remnant of Tycho's supernova (SN) represents the interaction between the SN ejecta and the companion star's envelope lost in the impact of the explosi...
A SEARCH FOR RADIO PULSARS IN THE NORTHERN SKY: DISCOVERY OF A PULSAR IN A UNIQUE BINARY SYSTEM
Search Radio pulsar The sky The pulsar. A binary system
2014/12/10
A sensitive search for pulsars has been conducted using the 92-meter transit telescope of the National Radio Astronomy Observatory. Nearly 50% of the sky north of +20(DEGREES) declination was searched...
