Japan bids to catch up on gene sequencing

Catch-Up and Leapfrog between the USA and Japan

The growth process for a technological leader is different from that of a follower. While followers can grow through imitation and capital deepening, a leader must undertake original research. This suggests that as the gap between the leader and the follower narrows, the follower must undertake more formal R&D and possibly face a slower overall growth rate. This paper examines these ideas by di...

Statistics catch-up lecture

Example 1. In a genetic study, n = 2217 patients are recruited, among which 1127 have bladder cancer. After whole genome sequencing, p = 475290 single nucleatide polymorphisms (or SNPs, a possible variation of the DNA sequence at one location) are measured on each patient. We construct a matrix X = (Xij)1≤i≤n,1≤j≤p where Xij = 1 if the ith patient has a mutation at jth location and 0 otherwise....

Catch-up Growth

Catch-up growth.

Catch-up growth, defined as growth velocity above the statistical limits of normality for age or maturity during a defined period of time, is distinguished from compensatory growth since it makes up for a potential loss rather than an actual loss and is seen in the whole body as opposed to specific organs. The cellular explanation for catch-up based on the work of Winick is described and a rece...

What's up on Twitter? Catch up with TWIST!

Event detection and analysis with respect to public opinion and sentiment in social media is a broad and well-addressed research topic. However, the characteristics and sheer volume of noisy Twitter messages make this a difficult task. This demonstration paper describes a TWItter event Summarizer and Trend detector (TWIST) system for event detection, visualization, textual description, and geo-...
