2024年7月14日,Trends in Biochemical Sciences杂志在线发表了中国科学院遗传与发育生物学研究所陆发隆研究组撰写的题为“Beyond simple tails: poly(A) tail-mediated RNA epigenetic regulation”的综述论文(DOI:10.1016/j.tibs.2024.06.013)。该论文总结了近年来关于RNA po...
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...
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...
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...
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 ...
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...
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...
The San Diego Supercomputer Center (SDSC) at the University of California, San Diego this week formally launched "Comet," a new petascale supercomputer designed to transform scientific research by exp...
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 ...
2MASS has provided a three-dimensional map of the >360 degree, wrapped tidal tails of the Sagittarius (Sgr) dwarf spheroidal galaxy, as traced by M giant stars. With the inclusion of radial velocity d...
Washington, D.C.--A two-person team of Carnegie's Scott Sheppard and Chadwick Trujillo of the Gemini Observatory has discovered a new active asteroid, called 62412, in the Solar System's main asteroid...

The stochastic multi-armed bandit problem is well understood when the reward distributions are sub-Gaussian. In this paper we examine the bandit problem under the weaker assumption that the distributi...
Oscillatory critical amplitudes have been repeatedly observed in hierarchical models and, in the cases that have been taken into consideration, these oscillations are so small to be hardly detectable....
Recovery and reuse of waste energy to reduce fuel dependence on petroleum fuel, and to alleviate emissions of contaminants is becoming an important policy for managing energy and the environment. In ...
Abstract: We establish new tail estimates for order statistics and for the Euclidean norms of projections of an isotropic log-concave random vector. More generally, we prove tail estimates for the nor...
