Draposa gen. nov. is proposed for eight wolf spider species from the Indomalayan Region, all of which were previously placed in the genus Pardosa: Draposa atropalpis (Gravely,1924) comb. nov., D. lyrivulva (Bösenberg & Strand, 1906) comb. nov. (=Pardosa leucopalpis Gravely, 1924 syn. nov.), D. nicobarica (Thorell, 1891) comb. nov., D. oakleyi (Gravely, 1924) comb. nov., D. porpaensis (U. A. Gaj...

This paper presents in-plane electrostatic comb-drive actuators with stroke as large as 245 μm that is achieved by employing a novel Clamped Paired Double Parallelogram (C-DPDP) flexure mechanism. For a given flexure beam length, comb gap, and actuation voltage, this is currently the largest comb-drive actuator stroke reported in the literature. The C-DP-DP flexure mechanism design offers high ...

The species of the subfamily Opiinae (Hymenoptera: Braconidae) from Hunan (Oriental China) are revised and illustrated. Thirty-six new species are described: Apodesmia bruniclypealis Li & van Achterberg, sp. n., Apodesmia melliclypealis Li & van Achterberg, sp. n., Areotetes albiferus Li & van Achterberg, sp. n., Areotetes carinuliferus Li & van Achterberg, sp. n., Areotetes striatiferus Li & v...

Part 1 of these studies described poly(methyl methacrylate-r-polyoxyethylene methacrylate) P(MMA-r-POEM) comb polymers that present Arg-Gly-Asp (RGD) peptides at a surface in nanoscale clusters on a protein-resistant background for control of cell adhesion. Here in part 2, we examine surface segregation of these peptide-modified and unmodified comb polymers blended with polylactide (PLA) as a s...

Cavity-enhanced direct frequency comb spectroscopy combines broad spectral bandwidth, high spectral resolution, precise frequency calibration, and ultrahigh detection sensitivity, all in one experimental platform based on an optical frequency comb interacting with a high-finesse optical cavity. Precise control of the optical frequency comb allows highly efficient, coherent coupling of individua...

Taxonomy and distribution of the genus Pterydrias Reitter, 1895 (Coleoptera: Ripiphoridae: Ripidiinae) are revised. Based on examination of the type material, the genus Pterydrias is confirmed as a senior synonym of the genus Eorhipidius Iablokoff-Khnzorian, 1986. Pterydrias debilis Reitter, 1895 is redescribed and illustrated, and its type locality is corrected to Haifa, Israel. The following ...

Frequency tunable comb resonators have been successfully designed and demonstrated based on a closed-form approach of a curved comb finger contour. Experimentally, the resonant frequency of a laterally driven comb resonator with 186 pairs of curved finger contour has been reduced by 55% from the initial frequency of 19 kHz under a bias voltage of 150 V. The corresponding effective stiffness has...

In this paper, we study the aperiodic comb signal from the point of view of the Fourier Transform. The comb is very important in the theory of ideal sampling. The knowledge of its properties is crucial for the establishment of suitable interpolation schemes. Here, we present sufficient conditions so that the Fourier Transform of an aperiodic comb is an aperiodic comb. We use this result to prop...
