Blind Signal Separation: Statistical Principles
, 2003
"... Blind signal separation (BSS) and independent component analysis (ICA) are emerging techniques of array processing and data analysis, aiming at recovering unobserved signals or `sources' from observed mixtures (typically, the output of an array of sensors), exploiting only the assumption of mut ..."

A Comparative Analysis of Methodologies for Database Schema Integration
- ACM COMPUTING SURVEYS
, 1986
"... One of the fundamental principles of the database approach is that a database allows a nonredundant, unified representation of all data managed in an organization. This is achieved only when methodologies are available to support integration across organizational and application boundaries.
Metho ..."

.
Methodologies for database design usually perform the design activity by separately producing several schemas, representing parts of the application, which are subsequently merged. Database schema integration is the activity of integrating the schemas of existing or proposed databases into a global, unified

SEPARATION, WEAK EXOGENEITY, AND P-T DECOMPOSITION IN COINTEGRATED VAR SYSTEMS WITH COMMON FEATURES
"... The aim of this paper is to study the concept of separability in multiple nonstationary time series displaying both common stochastic trends and common stochastic cycles. When modeling the dynamics of multiple time series for a panel of several entities such as countries, sectors, firms, imposing so ..."

into marginal cointegrating vectors as well as separating joint short-term dynamics into marginal short-term dynamics. Second, conditions for making permanent-transitory decompositions based on marginal systems are given. Third, issues of weak exogeneity are considered. Likelihood ratio type tests
Complex contagion and the weakness of long ties
, 2005
"... Complex Contagion and the Weakness of Long Ties The strength of weak ties is that they tend to be long – they connect socially distant locations. Recent research on “small worlds ” shows that remarkably few long ties are needed to give large and highly clustered populations the “degrees of separatio ..."

"... Atom interferometry, in which atomic waves are coherently split and later recombined, has been called the Swiss Army knife of atomic physics because of its numerous applications. Atom interferometers can be used to study gravity, observe quantum effects, and measure fundamental constants. However, t ..."

, the spitting of atomic beams has always been a challenging task. Several beam splitters for atoms have been developed over the years, many of which rely on complex, high-powered lasers whose photons collide with atoms to steer them along separate beam paths. [10] As our devices get ever smaller, so do
Weak updates and separation logic
"... Separation logic provides a simple but powerful technique for reasoning about low-level imperative programs that use shared data structures. Unfortunately, separation logic supports only “strong updates”, in which mutation to a heap location is safe only if a unique reference is owned. This limits t ..."

the applicability of separation logic when reasoning about the interaction between many high-level languages (e.g., ML, Java, C#) and low-level ones since the high-level languages do not support strong updates. Instead, they adopt the discipline of “weak updates”, in which there is a global “heap type ” to enforce
On the Bisectors of Weakly Separable Sets
, 2000
"... A bisector of two sets is the set of points equidistant to them. Bisectors arise naturally in several areas of computational geometry. We show that bisectors of weakly linearly separable sets in E d share many properties with separating lines. Among these, the bisector of a restricted class of line ..."
