We consider constraint-based methods for causal structure learning, such as the PC-, FCI-, RFCIand CCDalgorithms (Spirtes et al. (2000, 1993), Richardson (1996), Colombo et al. (2012), Claassen et al. (2013)). The first step of all these algorithms consists of the PCalgorithm. This algorithm is known to be order-dependent, in the sense that the output can depend on the order in which the variab...

Pattern recognition techniques form the heart of most, if not all, incoherent linear shift-invariant systems. When an object is recorded using a camera, information sampled by point spread function (PSF) system, replacing every with PSF in sensor. The sharp Kronecker Delta-like when numerical aperture (NA) large no aberrations. NA small, and system has aberrations, appears blurred. In case know...

background: safety climate is a description of employees' safety sharedconcepts about safety management. assessment of safety climate is one of therequirements for promoting safe behaviors in the workplace. nordic safetyclimate questionnaire (nosacq-50) is a valid tool for measuring safety climatethat its reliability and validity has been investigated in different languages.the aimof this study...

The taxonomy of Antarctic fishes has been predominantly based on morphological characteristics rather than on genetic criteria. A typical example is the Notothenia group, which includes N. coriiceps Richardson, 1844, N. neglecta Nybelin, 1951 and N. rossii Richardson, 1844. The Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP) technique was used to determine whet...

We introduce a mutation algorithm for puzzles that is a threedirection analogue of the classical jeu de taquin algorithm for semistandard tableaux. We apply this algorithm to prove our conjectured puzzle formula for the equivariant Schubert structure constants of two-step flag varieties. This formula gives an expression for the structure constants that is positive in the sense of Graham. Thanks...

The multigrid solution of coupled porous media and Stokes flow problems is considered. The Darcy equation as the saturated porous medium model is coupled to the Stokes equations by means of appropriate interface conditions. We focus on an efficient multigrid solution technique for the coupled problem, which is discretized by finite volumes on staggered grids, giving rise to a saddle point linea...

Stochastic Gradient Markov Chain Monte Carlo (SG-MCMC) algorithms have become increasingly popular for Bayesian inference in large-scale applications. Even though these methods have proved useful in several scenarios, their performance is often limited by their bias. In this study, we propose a novel sampling algorithm that aims to reduce the bias of SG-MCMC while keeping the variance at a reas...
