Atomic nuclei have only two ingredients, protons and neutrons, but the relative number of these ingredients makes a radical difference in their properties. Certain configurations of protons and neutro...
In early July, Comet NEOWISE approached the sun for the first time in nearly 4,500 years. For observers in the Northern Hemisphere, it is now faintly visible toward the Northwest after sunset. When vi...
New dinosaur with heart-shaped tail offers clues to evolution of Africa's ecosystems（图）
New dinosaur heart-shaped tail evolution of Africa ecosystems
2019/11/22
A dinosaur that wore its "heart" on its tail is providing new clues to how ecosystems evolved on the African continent during the Cretaceous Period some 100 million years ago, according to researchers...
Generalizations of Banaszczyk's transference theorems and tail bound
lattice techniques number theory
2018/3/6
We generalize Banaszczyk's seminal tail bound for the Gaussian mass of a lattice to a wide class of test functions. We therefore obtain quite general transference bounds, as well as bounds on the numb...
第四届重尾统计模型及其应用研讨会第一次通知（The 4th International Workshop on Statistical Modeling of Heavy-Tail Phenomena with Applications）
第四届 重尾统计模型及其应用 研讨会 第一次
2018/1/11
众所周知，金融、保险、网络等领域普遍存在的重尾现象引起了越来越多国内外学者的关注和重视。该领域的理论和应用已经成为应用概率统计界一个日益重要的学术分支。为加强国内外学者的交流和研究，推动本土学术活动的国际化，由苏州大学相关团队发起，经中国概率统计学会批准，第一届重尾统计模型及其应用研讨会曾于2012年在南京师范大学召开。此后，苏州大学和浙江工商大学于2014和2016年分别与中国概率统计学会联合举...

The 4th International Workshop Statistical Modeling of Heavy-Tail Phenomena with Applications
2017/12/20
Heavy-tailed distribution theory, alongside with extreme value theory, provide a framework and an indispensable set of tools aiming to analyze the data's atypical behaviors. The eld is driven by and ...
Lizard: Cut off the Tail! Practical Post-Quantum Public-Key Encryption from LWE and LWR
Post-Quantum Cryptography Public-Key Encryption Learning with Rounding (LWR)
2016/12/7
The Learning with Errors (LWE) is one of the most promising primitive for post-quantum cryptography due to its strong security reduction from the worst-case of NP-hard problems and its lightweight ope...
Complete Mitochondrial Genome Sequences of Chinese Indigenous Sheep with Different Tail Types and an Analysis of Phylogenetic Evolution in Domestic Sheep
Mitochondrial DNA Mitogenome Sheep Phylogenetic Mitochondrial Control Region
2016/5/20
China has a long history of sheep (Ovis aries [O. aries]) breeding and an abundance of sheep genetic resources. Knowledge of the complete O. aries mitogenome should facilitate the study of the evoluti...

Molecular forensics
2015/12/11
Millions of seahorses a year are traded internationally, with many eventually sold at retail shops as
curios, as aquarium pets, and especially for use in traditional medicine. The entire genus is now...

dimension reduction l1 norm Johnson-Lindenstrauss (JL) lemma Cauchy random projections
2015/8/21
For1 dimension reduction in the l1 norm, the method of Cauchy random projections multiplies the original data matrix A ∈ Rn×D with a random matrix R ∈ RD×k (k D) whose entries are i.i.d. samples of ...
Nonparametric Estimation of Tail Probabilities for the Single-Server Queue
Nonparametric Estimation Tail Probabilities Single-Server Queue
2015/7/8
We consider the estimation of tail probabilities in queues via the nonparametric estimator constructed by simple computing the observed fraction of time that the queue is out in the tail. We show that...
