A comparison between well-established parametric algorithms and the more recent Smyth algorithm for estimation of sinusoidal signals in white noise is presented. The comparison is performed through a pseudoMonte Carlo analysis on simulated data. The results obtained show that Smyth algorithm has a slightly better performance at large Signal-to Noise Ratios. However, when the SNR drops down, the...

We show that certain computational algorithms can be simulated on a quantum computer with exponential efficiency and be insensitive to phase errors. Our explicit algorithm simulates accurately the classical chaotic dynamics for exponentially many orbits even when the quantum fidelity drops to zero. Such phase-insensitive algorithms open new possibilities for computation on realistic quantum com...

This paper explores two classes of model adaptation methods for Web search ranking: Model Interpolation and error-driven learning approaches based on a boosting algorithm. The results show that model interpolation, though simple, achieves the best results on all the open test sets where the test data is very different from the training data. The tree-based boosting algorithm achieves the best p...

In order to use handwriting as a universal manmachine interface, we assume a special pen device, called data-embedding pen, which can embed binary data into handwriting as a sequence of invisible ink drops along the handwriting in a real-time manner. This paper describes the assumed hardware, applications, and required technologies of the data-embedding pen. Especially, an accurate stroke recov...

purpose: to evaluate the adverse effects of intravitreal injection of sterile chloramphenicol eye drops on corneal endothelial cells of donated corneas. methods: 100 donor corneas were enrolled in the study. one eye of each donor underwent intravitreal injection of sterile chloramphenicol eye drops following vitreous tap and the fellow eyes were served as controls. after corneo-scleral excision...

Slow slip events (SSEs) are another mode of fault deformation than the fast faulting of regular earthquakes. Such transient episodes have been observed at plate boundaries in a number of subduction zones around the globe. The SSEs near the Boso Peninsula, central Japan, are among the most documented SSEs, with the longest repeating history, of almost 30 y, and have a recurrence interval of 5 to...
