A Scalable Architecture for Harvest-Based Digital Libraries - The ODU/Southampton Experiments
No full textThis paper discusses the requirements of current and emerging applications based on the Open Archives Initiative (OAI) and emphasizes the need for a common infrastructure to support them. Inspired by HTTP proxy, cache, gateway and web service concepts, a design for a scalable and reliable infrastructure that aims at satisfying these requirements is presented. Moreover it is shown how various applications can exploit the services included in the proposed infrastructure. The paper concludes by discussing the current status of several prototype implementations

Immanus trolaki Beaver & Sittichaya & Liu 2019, n. comb.
No full textImmanus trolaki (Schedl) n. comb. Xyleborus trolaki Schedl, 1939: 350. Ambrosiodmus trolaki (Schedl): Wood & Bright, 1992: 681. Diagnosis: Elytral declivity steeply truncate with a distinct marginal costa laterally, but not in upper part of declivity, its face opaque, covered with fine, setose granules on both striae and interstriae so that they are not easily distinguished. Second interstriae not raised on declivity with two large tubercles in mid-declivity. Anterior margin of pronotum with 6‒8 separate asperities. Small species, 4.0 mm long. Taxonomy: The senior author has examined a paralectotype (BMNH). The species has the characters of Immanus, and is therefore transferred to that genus from Ambrosiodmus. Distribution: East and West Malaysia. Biology: Recorded from Lophopetalum (Celastraceae) and Cinnamomum (Lauraceae) (Schedl 1939).Published as part of Beaver, R. A., Sittichaya, W. & Liu, Y., 2019, A review of the genus Immanus Hulcr & Cognato with a key to species (Coleoptera: Curculionidae: Scolytinae: Xyleborini), pp. 378-386 in Zootaxa 4585 (2) on page 385, DOI: 10.11646/zootaxa.4585.2.11, http://zenodo.org/record/263727
Mouse models of gallstone disease
No full textPURPOSE OF REVIEW: The establishment of mouse models of gallstones, and the contribution of mouse models to genetic studies of gallstone disease, as well as the latest advances in the pathophysiology of gallstones from mouse experiments are summarized. RECENT FINDINGS: The combined uses of genomic strategies and phenotypic studies in mice have successfully led to the identification of many Lith genes, which pave the way for the discovery of human LITH genes. The physical-chemical, genetic, and molecular biological studies of gallstone disease in mice with knockout or transgene of specific target genes have provided many novel insights into the complex pathophysiological mechanisms of this very common hepatobiliary disease worldwide, showing that interactions of five primary defects play a critical role in the pathogenesis of cholesterol gallstones. Based on mouse studies, a new concept has been proposed that hepatic hypersecretion of biliary cholesterol is induced by multiple Lith genes, with insulin resistance as part of the metabolic syndrome interacting with cholelithogenic environmental factors to cause the phenotype. SUMMARY: The mouse model of gallstones is crucial for elucidating the physical-chemical and genetic mechanisms of cholesterol crystallization and gallstone formation, which greatly increase our understanding of the pathogenesis of this disease in humans
