Commentary: Development of a new concept is achieved only step-by-step

Commentary: Sex education interventions: increasing knowledge is only a first step.

aim of sex education interventions should be to reduce the adverse outcomes of sexual intercourse. This includes unplanned pregnancies and sexually transmitted infection rates. The findings of the most recent systematic review of interventions to reduce unintended pregnancies amongst adolescents, using the results exclusively from randomized trials in developed countries , are disappointing. 1 ...

Adaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm

 A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...

A step by step organisational development framework for facilities management

Organisations who have expertise in their use of IT are invited to approach the Centre. Please contact the administrators if you wish to become a member. On behalf of the Secretary of State for Health my business is developing policy and improving performance of buildings and services within the NHS, the largest estate portfolio under Government responsibility in Europe.

From Averaging to Acceleration, There is Only a Step-size

We show that accelerated gradient descent, averaged gradient descent and the heavyball method for non-strongly-convex problems may be reformulated as constant parameter second-order difference equation algorithms, where stability of the system is equivalent to convergence at rate O(1/n), where n is the number of iterations. We provide a detailed analysis of the eigenvalues of the corresponding ...
