We have theoretically and experimentally investigated the dynamics of frequency comb generation insilicon-based microresonators. In this system, the parametric gain associated with the nonlinear process offour-wave mixing leads to parametric oscillation and generation of signal/idler sidemodes.This report describes our results that further develop the parametric comb technology. We ...
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...
We demonstrate phase stable, mJ-level parametric amplification of pulse pairs originating from a Ti:Sapphire frequency comb laser. The amplifier-induced phase shift between the pulses has been determined interferometrically with an accuracy of approximately 10 mrad. Typical phase shifts are on the order of 50-200 mrad, depending on the operating conditions. The measured phase-relation can be as...
Supramolecular self-assembly of block copolymers in aqueous solution has received ever-increasing interest over the past few decades due to diverse biological and technological applications in drug delivery, imaging, sensing and catalysis. In addition to relative block lengths, molecular weights and solution conditions, chain architectures of block copolymers can also dramatically affect their ...
Artificial intelligence is the path choice for development of industry and enterprise intelligence. In era intelligence, artificial its supporting data technologies are increasingly becoming driving force development, but these new data-dependent smart platforms enabling models still unclear. Thus further comb analysis evolution path, big can assign rules enterprise, relying on intensive, super...
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...
Two proctophyllodid species described by Herbert F. Berla were studied, re-described and their generic status was re-evaluated. A new genus, Lamellodectes gen. nov. (Proctophyllodidae: Pterodectinae), is erected to accommodate Pterodectes ocelatus Berla, 1960 from the White-collared Foliage-gleaner, Anabazenops fuscus (Vieillot) (Furnariidae), and a new species, L. distinctus sp. nov., from the...
The meter of a musical excerpt provides high-level rhythmic information and is crucial to many Music Information Retrieval tasks. We investigate the use of a computationally efficient approach to metrical analysis based on psycho-acoustically motivated decomposition of the audio signal. A twostage comb filter-based approach, originally proposed for double/ triple meter estimation, is extended t...

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...
