The Afrotropical genus-group taxa Dymantis Stål, 1861 and Eomyrochea Linnavuori, 1982 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Myrocheini) are confirmed as objective synonyms, both sharing the same type species: Dymantis subvittata Stål, 1861. As a result, Dymantis (= Eomyrochea, syn. confirm.) is downgraded to a subgenus of Myrochea Amyot and Serville, 1843 and a new genus, Neodyma...

The comb filter is one of the basic building blocks in the world of digital filtering and signal processing, and an important component in a wide variety of musical and non-musical applications ranging from anti-aliasing of images and video to the design of numerous traditional audio effects. This paper describes a technique of using nested comb filter structures in order to design computationa...

A technique is presented for generating optical frequency combs centered at arbitrary wavelengths by use of cross-phase modulation (XPM) between a femtosecond pulse train and a cw laser beam by copropagating these signals through an optical fiber. We report results from use of this method to place a 90-MHz frequency comb on an iodine-stabilized Nd:YAG laser at 1064 nm and on a frequency-doubled...

We report on frequency comb generation at 1.5 μm by injection of a CW laser in a hybridly1 mode-locked InAs/InP two-section quantum-dot laser (HMLQDL). The generated comb has > 60 modes spaced by ∼ 4.5 GHz and a -20 dBc width of> 100 GHz (23modes) at> 30 dB signal to background ratio. Comb generation was observed with the CW laser (red) detuned more than 20 nm outside the HMLQDL spectrum, spann...

In this paper, an iterative optimization algorithm, called the Comb algorithm, is presented for approximating the global solution to MAP image restoration and segementation. The Comb derives new initial conngurations based on the best local minimum found so far and leads a local search towards the global minimum. Experimental comparisons show that the Comb produces solutions of quality comparab...

Based on examination of holotypes or interpretation of original descriptions, four taxonomic changes are proposed for South American species erroneously placed in the tribe Smiliini: Flynnia, gen. n. (Thuridini) and F. fascipennis (Funkhouser), comb. n. from Bolivia; Antianthe atromarginata (Goding), comb. n. from Ecuador; Amastris pilosa (Funkhouser), comb. n. from Peru; and Thelia planeflava ...

An electrostatically driven micromirror is described. The vertical comb of a three-dimensional microstructure is realized by bending the device wafer having microstructures. By resetting the bending angle, the tuning of the vertical gap between moving and stationary combs is possible. The characteristics of the vertical comb drive actuator can be tuned, confirming the performance. key words: mi...

We have performed sub-Doppler spectroscopy on the narrow intercombination line of cold calcium atoms using the amplified output of a femtosecond laser frequency comb. Injection locking of a 657-nm diode laser with a femtosecond comb allows for two regimes of amplification, one in which many lines of the comb are amplified, and one where a single line is predominantly amplified. The output of th...

A semiconductor laser under negative optoelectronic feedback is applied to the generation of a microwave frequency comb through the nonlinear dynamics. The laser system is operated in a harmonic frequency-locked pulsing state, where its power spectrum is a microwave frequency comb that consists of multiples of a locking frequency. Every frequency component of the comb can be simultaneously stab...

We introduce a novel broadband optical frequency comb generator consisting of a parametric oscillator with an intracavity electro-optic phase modulator. The parametric oscillator is pumped by 532-nm light and produces near-degenerate signal and idler fields. The modulator generates a comb structure about both the signal and the idler. Coupling between the two families of modes results in a disp...
