Tversky (1972) has proposed a family of models for paired-comparison data that generalize the Bradley-Terry-Luce (BTL) model and can, therefore, apply to a diversity of situations in which the BTL model is doomed to fail. In this article, we present a Matlab function that makes it easy to specify any of these general models (EBA, Pretree, or BTL) and to(More)
Reduced supply of the amino acid methionine increases longevity across species through an as yet elusive mechanism. Here, we report that methionine restriction (MetR) extends yeast chronological lifespan in an autophagy-dependent manner. Single deletion of several genes essential for autophagy (ATG5, ATG7 or ATG8) fully abolished the longevity-enhancing(More)
Linear optics quantum logic gates are the best tool to generate multiphoton entanglement. Simplifying a recent approach, we were able to implement the conditional phase gate with only one second-order interference at a polarization dependent beam splitter, thereby significantly increasing its stability. The improved quality of the gate is evaluated by(More)
— This paper is concerned with the adaptive sliding-mode control of a class of nonlinear systems in nonlinear parametric-pure-feedback form with mismatched uncertainties. Backstepping design procedure is applied, which leads to a new adaptive sliding-mode control. Gaussian radial-basis-function networks are used to approximate the unknown system dynamics. A(More)
The methylotrophic yeast Pichia pastoris (Komagataella phaffii) is one of the most commonly used expression systems for heterologous protein production. However the recombination machinery in P. pastoris is less effective in contrast to Saccharomyces cerevisiae, where efficient homologous recombination naturally facilitates genetic modifications. The lack(More)
Linear-optics quantum logic operations enabled the observation of a four-photon cluster state. We prove genuine four-partite entanglement and study its persistency, demonstrating remarkable differences from the usual Greenberger-Horne-Zeilinger (GHZ) state. Efficient analysis tools are introduced in the experiment, which will be of great importance in(More)
This paper presents results from the IST KAII Trial project ReLAX – Remote LAboratory eXperimentation trial (IST 1999-20827), and contributes with a framework for a global remote laboratory experimentation network supported by a new business model. The paper presents this new Experiment Service Provider business model that aims at bringing physical(More)
We present a simple and practical protocol for the solution of a secure multiparty communication task, the secret sharing, and its proof-of-principle experimental realization. In this protocol, a secret is split among several parties in a way that its reconstruction requires the collaboration of the participating parties. In our scheme the parties solve the(More)
