NEW HAMPSHIRE TENTHREDINIDÆ
Authors: Macgillivray Alex. D. 
Published: February 2010

The new species described below were contained in a collection of saw-flies recently from Mrs. Annie Trumbull Slosson, and were collected on Mount Washington and at Franconia, New Hampshire. The collection was of interest on account of the number of species it contained which are evidently related to a boreal fauna.Macrophya mixta,n. sp.—♀ Black, with the following parts white: two spots on the clypeus, the labrum, a spot on each mandible, two spots on the occiput pseudocaudad of the ocelli, a narrow line on collar and tegulæ, the anterior coxæ at apex and a narrow line at side, the middle and posterior coxæ at apex, the trochanters, the distal halves of the anterior femora, the anterior tibiæ beneath, the knees of the middle, all the tarsi except the base of the first segment and the apices of the others, a large spot on the posterior coxæ.
THE COLEOPTERA OF CANADA
Authors: Wickham H. F. 
Published: February 2010

The species included here are of rather short, cylindrical form, sometimes suggesting in shape the Cryptocephalini, though easily separated, so far as our genera are concerned, by the shorter and stouter antennæ. Most of them are Southern or Western in distribution, and the few genera recorded from within our limits may be known among themselves by these characters:—A. Front coxæ contiguous.

None of the species herein described or listed are as much as 10 mm. long.I. Marginal cell truncate: The species of this section are not true Andrena, but will form a distinct genus, apparently as near to Prosapis as to Andreua. Two of the larger species, A. asclepiadis, Ckll., and A. mexicanorum, Ckll., are congeneric. I have before me also a species from Texas.
THE COLEOPTERA OF CANADA
Authors: Wickham H. F. 
Published: February 2010

Most of the members of this tribe are of at least moderate size, and are often quite ornately coloured. In form they are usually robust and convex, while lacking the rotundity of the Cryptocephalini. The genera of Eastern Canada may be arranged thus, the characters used being in the main drawn from the Leconte and Horn “Classification”:—A. Anterior coxal cavities closed, metasternum long; reddish-yellow above, with black stripes. Entomoscelis.

DESCRIPTION OF TWO REMARKABLE ABERRATIONS OF COLIAS PHILODICE
Authors: Brainerd Dwight 
Published: February 2010

We were fortunate in taking a very peculiar pair of Colias philodice this summer. They were captured at Edgartown, Mass., in a litrle salt marsh, August 10th and 14th respectively, and, though hatched during the hot wave, we believe are blood relations — part of a sport brood.Many specimens were examined at the time, but no other departures from the type found.
SOME ANTS AND MYRMECOPHILOUS INSECTS FROM TORONTO
Authors: King Geo. B. 
Published: February 2010

During the summer of 1896 I received specimens of ants collected by Mr. R. J. Crew, of Toronto, in exchange for such Coleoptera as I could find for him in my locality. He writes me that he noticed no insects with the ants other than the Coleopteta and some aphids in a nest of ants, but did not capture any.I have found, however, upon looking them over, they contain several very interesting species of various orders: some truly myrmecophilous, some occasional, while others were brought into the nests by the ants, to be used by them for food; this will apply to a number of Hemiptera collected by Formica subsericea, Say.

SOME NEW AND LITTLE-KNOWN DORYDINI (Jassinæ)
Authors: Baker C. F. 
Published: February 2010

Spangbergiella vulnerata, Uhler.—There are two specimens of this species in the National Museum collection from New York, and another in Fitch collection from Arkansas.Spangbergiella Lynchii, Berg.—Signoret quotes the description of this species in his Essai sur les Jassides and says: “This species might well be the S. vulneratus.” Berg takes this suggestion as the final disposition of the species, and reduces Lynchii to a synonym of vulnerata. I have a specimen of what is undoubtedly this species, from the Herbert H. Smith collection taken at Corumba. While it is very near vulnerata. still I think it should retain its place as a good species.
THE HIND WINGS OF THE DAY BUTTERFLIES
Authors: Grote A. Radcliffe 
Published: February 2010

I wish to offer here a few remarks on the structure of the hind wings of the diurnals especially, in extension of my recent paper on the Butterflies of Hildesheim.The first point relates to the fact that the hind wings are more specialized as compared with the primaries. The probable explanation I offer is, that the hind wings bear more of the weight of the body (abdomen), and that they regulate the downward stroke of the fore wings.

Authors: Sim So Hee , Lee Sang Ick , Park Ji Hoon , Chung Young Keun 
Published: February 2010

AbstractFrom cyclohexadienyl alkynes with a terminal alkyne unit, double cyclopropanated products were obtained in reasonable to high yields. For cyclohexadienyl alkynes substituted at the alkyne unit, cyclopropanated products were obtained in high yields. When a keto carbonyl group was introduced to cyclohexadienyl alkynes with a substituted alkyne, Alder‐ene‐type products were obtained in reasonable to high yields.

Mixture Bayesian regularization method of PPCA for multimode process monitoring
Authors: Ge Zhiqiang , Song Zhihuan 
Published: February 2010

AbstractThis article intends to address two drawbacks of the traditional principal component analysis (PCA)‐based monitoring method: (1) nonprobabilistic; (2) single operation mode assumption. On the basis of the monitoring framework of probabilistic PCA (PPCA), a Bayesian regularization method is introduced for performance improvement, through which the effective dimensionality of the latent variable can be determined automatically. For monitoring processes with multiple operation modes, the Bayesian regularization method is extended to its mixture form, thus a mixture Bayesian regularization method of PPCA has been developed. To enhance the monitoring performance, a novel probabilistic strategy has been proposed for result combination in different operation modes. In addition, a new mode localization approach has also been developed, which can provide additional information and improve process comprehension for the operation engineer. A numerical example and a real industrial application case study have been used to evaluate the efficiency of the proposed method. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Multiscale dynamic Monte Carlo/continuum model of drying and nonideal polycondensation in sol‐gel silica films
Authors: Li Xin , Rankin Stephen E. 
Published: February 2010

AbstractThe process of forming sol‐gel silica thin films involves multiple length and time scales ranging from molecular to macroscopic, and it is challenging to fully model because the polymerization is nonideal. A multiscale model is described to link macroscopic flow and drying (controlled by process parameters) to film microstructure (which dictates the properties of the films). In this modeling strategy, dynamic Monte Carlo (DMC) polymerization simulations are coupled to a continuum model of drying. The entire DMC simulation is treated as a particle of sol whose position and composition are tracked using a diffusion/evaporation finite difference method. By simulating swarms of particles starting from different positions in the film, the multiscale model predicts different drying/gelation phenomena, and predicts the occurrence of gradients of concentration and gelation in the films which can lead to the formation of a gel skin near the top surface of the film. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Synthesis of Poly(vinyl alcohol)/C60 and Poly(N‐vinylpyrrolidone)/C60 Nanohybrids as Potential Photodynamic Cancer Therapy Agents
Authors: Hurtgen Marie , Debuigne Antoine , Mouithys‐Mickalad Ange , Jérôme Robert , Jérôme Christine , Detrembleur Christophe 
Published: February 2010

AbstractWell‐defined poly(vinyl acetate) (PVAc) and poly(N‐vinylpyrrolidone)‐co‐poly(vinyl acetate) (PNVP‐co‐PVAc) chains end‐capped by Co(acac)2 (acac=acetylacetonate) and prepared by cobalt‐mediated radical polymerization (CMRP) are grafted onto a fullerene. Homolytic CoC bond cleavage of the polymer chain ends at 30 °C releases the polymeric radicals that add onto C60, thereby leading to the corresponding PVAc/C60 and PNVP‐co‐PVAc/C60 nanohybrids. The [polymer–Co(acac)2]/[C60] molar ratio was varied to adjust the structure of the nanohybrids, and more particularly the number of grafted arms. Finally, the potential of the hydrosoluble PVOH/C60 nanohybrids, which result from the methanolysis of the ester groups of PVAc/C60, and of the PNVP‐co‐PVAc/C60 nanohybrids as photosensitizers for photodynamic therapy (PDT), was approached. First, photobleaching tests demonstrated the ability of these nanohybrids to produce singlet oxygen upon irradiation, which can play a role in cell damage. Second, cell viability assays demonstrated that both types of nanohybrids are deprived of intrinsic cytotoxicity in the dark, whereas they promoted significant cell mortality when subjected to light treatment. The selective response of these materials to irradiation makes them promising compounds for PDT.
A Note on Variance Estimation of the Aalen–Johansen Estimator of the Cumulative Incidence Function in Competing Risks, with a View towards Left‐Truncated Data
Authors: Allignol Arthur , Schumacher Martin , Beyersmann Jan 
Published: February 2010

AbstractThe Aalen–Johansen estimator is the standard nonparametric estimator of the cumulative incidence function in competing risks. Estimating its variance in small samples has attracted some interest recently, together with a critique of the usual martingale‐based estimators. We show that the preferred estimator equals a Greenwood‐type estimator that has been derived as a recursion formula using counting processes and martingales in a more general multistate framework. We also extend previous simulation studies on estimating the variance of the Aalen–Johansen estimator in small samples to left‐truncated observation schemes, which may conveniently be handled within the counting processes framework. This investigation is motivated by a real data example on spontaneous abortion in pregnancies exposed to coumarin derivatives, where both competing risks and left‐truncation have recently been shown to be crucial methodological issues (Meister and Schaefer (2008), Reproductive Toxicology 26, 31–35). Multistate‐type software and data are available online to perform the analyses. The Greenwood‐type estimator is recommended for use in practice.
Study of nobiletin binding to bovine serum albumin by capillary electrophoresis–frontal analysis and circular dichroism
Authors: Yi Lian , Li Hailing , Deng Qingqing , Yuan Zhongzheng 
Published: February 2010

AbstractA very recent epidemiological study provided strong support for nobiletin (NOB) as a potential candidate chemopreventive agent against cancer. From the pharmacology point of view, drug–protein interactions are determining factors in therapeutic, pharmacodynamic and toxicological drug properties. In this work, for the first time, detection of NOB at near‐physiological conditions was accomplished by means of capillary electrophoresis–frontal analysis (CE‐FA), and then the binding constants of NOB with bovine serum albumin (BSA) at the same conditions were determined. Complexation of NOB–BSA led to a decrease of the height for free NOB with increasing concentration of BSA. These results revealed the presence of a single class of binding site on BSA, and provided the binding constant of 103/m, showing the strong affinity of NOB for BSA. Furthermore, circular dichroism spectra showed that, when the molar ratio of NOB to BSA was up to 2:1, NOB did not affect the overall protein conformation significantly and the protein thus retained a native‐like structure. These results may provide important information for preclinical studies of nobiletin in pharmaceutical research. Copyright © 2010 John Wiley & Sons, Ltd.
Cloning and Characterization of the Ravidomycin and Chrysomycin Biosynthetic Gene Clusters
Authors: Kharel Madan K. , Nybo S. Eric , Shepherd Micah D. , Rohr Jürgen 
Published: February 2010

AbstractThe gene clusters responsible for the biosynthesis of two antitumor antibiotics, ravidomycin and chrysomycin, have been cloned from Streptomyces ravidus and Streptomyces albaduncus, respectively. Sequencing of the 33.28 kb DNA region of the cosmid cosRav32 and the 34.65 kb DNA region of cosChry1‐1 and cosChryF2 revealed 36 and 35 open reading frames (ORFs), respectively, harboring tandem sets of type II polyketide synthase (PKS) genes, D‐ravidosamine and D‐virenose biosynthetic genes, post‐PKS tailoring genes, regulatory genes, and genes of unknown function. The isolated ravidomycin gene cluster was confirmed to be involved in ravidomycin biosynthesis through the production of a new analogue of ravidomycin along with anticipated pathway intermediates and biosynthetic shunt products upon heterologous expression of the cosmid, cosRav32, in Streptomyces lividans TK24. The identity of the cluster was further verified through cross complementation of gilvocarcin V (GV) mutants. Similarly, the chrysomycin gene cluster was demonstrated to be indirectly involved in chrysomycin biosynthesis through cross‐complementation of gilvocarcin mutants deficient in the oxygenases GilOII, GilOIII, and GilOIV with the respective chrysomycin monooxygenase homologues. The ravidomycin glycosyltransferase (RavGT) appears to be able to transfer both amino‐ and neutral sugars, exemplified through the structurally distinct 6‐membered D‐ravidosamine and 5‐membered D‐fucofuranose, to the coumarin‐based polyketide derived backbone. These results expand the library of biosynthetic genes involved in the biosyntheses of gilvocarcin class compounds that can be used to generate novel analogues through combinatorial biosynthesis.
