The endemic Australian genus Neodialineura Mann is revised to include 13 species. Three species are previously described: N. nitens (White) and N. saxatilis (White) from southern mainland Australia and Tasmania, and N. striatithorax Mann from eastern Australia. Ten species are described as new, including N. ataxia sp. nov., N. atmis sp. nov., N. bagdad sp. nov, N. bifaria sp. nov., N. litura sp. nov., N. polygramma sp. nov., N. signum sp. nov., N. spinosasp. nov., N. tessella sp. nov. and N. trichidion sp. nov. This revision serves as an empirical example for modernising the process of documenting global biodiversity by making taxonomic description and key development more efficient by avoiding redundancy in data handling and using digital media. Complete taxonomic descriptions were generated using online specimen and image datab...
A new species of the North American genus Pseudatrichia Osten Sacken is described. Pseudatrichia bezarki sp. nov. is described based on a male and female reared from wood-boring beetle galleries in Pinus sp. from Arizona (United States).
This paper discusses the following key messages. Taxonomy is (and taxonomists are) more important than ever in times of global change. Taxonomic endeavour is not occurring fast enough: in 250 years since the creation of the Linnean Systema Naturae, only about 20% of Earth’s species have been named. We need fundamental changes to the taxonomic process and paradigm to increase taxonomic productivity by orders of magnitude. Currently, taxonomic productivity is limited principally by the rate at which we capture and manage morphological information to enable species discovery. Many recent (and welcomed) initiatives in managing and delivering biodiversity information and accelerating the taxonomic process do not address this bottleneck. Development of computational image analysis and feature extraction methods is a crucial missing cap...
Late in life the writer and scholar Ueda Akinari (1734-1809) suffered the loss of two individuals near to him, as well as his eyesight. He recounts his suffering in a distinctive manner, by creating an exchange of letters between himself and his deceased wife, Koren, generated in the context of a dream encounter with his recently departed caregiver. This essay examines Akinari's "Yomotsu fumi (よもつ文、Letter from the Nether Realm)", and analyses the content of the work, in particular the use of the Daoist classic Liezu (c. 4th century CE). The essay argues against a reading of Akinari's text as a passive record of a dream, even a highly vivid one, and rather proposes an interpretation of the text as a carefully crafted literary construct, complete with references to Chinese philosophical texts in addition to references from the Japanese c...
This atlas is a response to the increasing demand for weld metals of high toughness at low temperatures with the appropriate microstructures. These diagrams will assist welding engineers, welding metallurgists and welding-consumables designers in industry as well as those investigating steel weld metal phase transformation kinetics.
This paper evaluates the energy savings potential of multi-cell cooling tower optimal sequencing control methods. Annual tower fan energy usage is calculated for a counter-flow tower with multiple variable-speed fans. Effectiveness-NTU tower model is employed to predict the cooling tower performance at various conditions. Natural convection when the fan is off is accounted by using an assumed airflow rate. The energy savings at five cities representing different typical climates are studied using typical meteorological year data. The results show that, if the tower capacity can be increased by 50% and 100% by running extra tower cells, the annual total fan power usage can be reduced by 44% and 61%, respectively. A cumulative saving percent curve is generated to help estimate the annual total savings percent when extra cooling tower cap...
Signal transduction pathways play important roles in cell differentiation, proliferation, and survival. Specific protein-protein interactions mediate the assemblies of protein complexes in response to different signals therefore regulate the proper transmission of cellular signals. Inappropriate protein-protein interactions within signalling pathways can lead to many diseases, including cancer. Proteomics-based approaches, which enable the quantitative investigation of protein-protein interactions involved in signalling networks, provide us with techniques to define the molecules controlling various signalling pathways. The small GTPase Rap1 belongs to the Ras family and shares high similarity with Ras protein. Rap1 cycles between an inactive GDP-bound state and an active GTP-bound state. This cycle is regulated by guanine nucleotide e...
