In this paper, we use evidence from our earlier review of surgical randomised controlled trials with a placebo arm to show that blinding Vest in trials of interventional procedures is feasible.We give examples of ingenious strategies that have been used to simulate the active procedure and to make the placebo control indistinguishable from the acti
The forward search (FS) is a general method of robust data fitting that moves smoothly from very robust to maximum likelihood estimation.The regression procedures are included in the MATLAB toolbox FSDA.The work on a SAS version of the FS originates from the need for the analysis of large datasets expressed by law enforcement services operating in
Self-supervised learning methods have received much attention in skeleton-based human action recognition.These methods rely on pretext tasks to utilize unlabeled data and learn an effective feature encoder.In this paper, a novel self-supervised learning method is proposed.First, we design a new pretext task called view enhanced jigsaw puzzle (VEJP)
A novel method to determine the dispersion of the quadratic electro-optic effect in nonlinear optical materials by using a silicon-on-insulator microring resonator is presented.The microring consists of a silicon slot waveguide enabling large dc electric field strength at low applied voltages.The dispersion of third-order hyperpolarizability of a l
