We consider the Independent Subspace Analysis problem from the point of view of contrast functions, showing that contrast functions are able to partially solve the ISA problem. That is, basic ICA can solve the ISA problem up to within-subspace separation/analysis. We define suband super-Gaussian subspaces and extend to ISA a previous result on freedom of ICA from local optima. We also consider ...

In consultation with international schools in the East Asian region, ACER learned about the need for an assessment instrument designed for their particular populations. Although many schools were using existing external assessment for monitoring and self-evaluation, there was a general sense that, because these were primarily designed for national use, they did not cater for students from diver...

This meta-analysis was conducted to synthesize the effect of 22 primary studies which have been conducted to test the effect of the integrated skills approach (ISA) on language skills and components. Three questions guide this analyses: What is the overall effect of ISA  on language skills and sub-skills? To what extent moderator variables such as learners level of education and proficiency mod...

BACKGROUND Incomplete stent apposition (ISA) is an unusual finding of intravascular ultrasound (IVUS) that may occur both after drug-eluting stent (DES) or bare-metal stent (BMS) implantation and could be associated with late stent thrombosis. Controversy still remains about whether the risk of late-acquired ISA is increased after DES implantation. This meta-analysis aimed to clarify whether DE...

BACKGROUND We sought to determine the relationship between the size of the left atrial isolated surface area (ISA) after pulmonary vein antrum isolation for paroxysmal atrial fibrillation (AF) and rhythm outcome during a 12-month follow-up. METHODS AND RESULTS One hundred one consecutive patients with paroxysmal AF (mean age, 59±11 years; median [range] AF history, 36 [24-96] months; mean lef...

This rough diamond presents a new domain-specific language (DSL) for producing detailed models of Instruction Set Architectures, such as ARM and x86. The language’s design and methodology is discussed and we propose future plans for this work. Feedback is sought from the wider theorem proving community in helping establish future directions for this project. A parser and interpreter for the DSL...

We treat the problem of searching for hidden multidimensional independent auto-regressive processes. First, we transform the problem to Independent Subspace Analysis (ISA). Our main contribution concerns ISA. We show that under certain conditions, ISA is equivalent to a combinatorial optimization problem. For the solution of this optimization we apply the cross-entropy method. Numerical simulat...

This study assessed the relative effects of two intelligent speed adaptation (ISA) systems (informative and actively supporting) on simulated driving performance and acceptability in a sample of inexperienced and experienced drivers. Participants drove a series of simulated drives under three conditions: no ISA (control), ISA informative and ISAactively supporting. The informative systemsignifi...

Abstract This article examines the creation of International Solar Alliance (ISA), a new international organization led by India and backed primarily developing countries. Official documents wide-ranging interviews offer insights into treaty-making process. Using political economy approach to study law, analyzes politico-legal issues associated with ISA. The legal form ISA is best described as ...
