Dactylotrochus cervicornis (≤ Tridacophyllia cervicornis Moseley, 1881), which occurs in Indo-Pacific waters between 73 and 852m, was originally described as an astraeid but was later transferred to the Caryophylliidae. Assumed to be solitary, this species has no stolons and only one elongated fossa, and is unique among azooxanthellate scleractinians in often displaying extremely long thecal extensions that are septate and digitiform. Based on both molecular phylogenetic analyses (partial mitochondrial CO1 and 16S rDNA, and partial nuclear 28S rDNA) and morphological characteristics, we propose the transfer of D. cervicornis from the Caryophylliidae to the Agariciidae, making it the first extant representative of the latter family that is solitary and from deep water (azooxanthellate). The basal position of D. cervicornis within the agariciids implied by our analyses strengthens the case for inclusion of fossil species that were solitary, such as Trochoseris, in this family and suggests that the ancestor of this scleractinian family, extant members of which are predominantly colonial and zooxanthellate, may have been solitary and azooxanthellate. © 2012 CSIRO.

Ethics and Information Technology | Year: 2011

We argue that the notion of trust, as it figures in an ethical context, can be illuminated by examining research in artificial intelligence on multi-agent systems in which commitment and trust are modeled. We begin with an analysis of a philosophical model of trust based on Richard Holton's interpretation of P. F. Strawson's writings on freedom and resentment, and we show why this account of trust is difficult to extend to artificial agents (AAs) as well as to other non-human entities. We then examine Margaret Urban Walker's notions of "default trust" and "default, diffuse trust" to see how these concepts can inform our analysis of trust in the context of AAs. In the final section, we show how ethicists can improve their understanding of important features in the trust relationship by examining data resulting from a classic experiment involving AAs. © 2010 Springer Science+Business Media B.V.

Aquaporins (AQPs) are water channel proteins facilitating movement of water across the cell membrane. Recent insect studies clearly demonstrate that AQPs are indispensable for cellular water management under normal conditions as well as under stress conditions including dehydration and cold. In the present study we cloned an AQP cDNA from the Antarctic midge Belgica antarctica (Diptera, Chironomidae) and investigated water transport activity of the AQP protein and transcriptional regulation of the gene in response to dehydration and rehydration. The nucleotide sequence and deduced amino acid sequence of the cDNA showed high similarity to AQPs in other insects and also showed characteristic features of orthodox AQPs. Phylogenetic analysis revealed that Belgica AQP is a homolog of dehydration-inducible AQP of another chironomid, Polypedilum vanderplanki. A swelling assay using a Xenopus oocyte expression system verified that Belgica AQP is capable of transporting water, but not glycerol or urea. The AQP mRNA was detected in various organs under non-stressed conditions, suggesting that this AQP plays a fundamental role in cell physiology. In contrast to our expectation, AQP transcriptional expression was not affected by either dehydration or rehydration. © 2011 Elsevier Ltd.

The movement of water and small solutes is integral to the survival of freezing and desiccation in insects, yet the underlying mechanisms of these processes are not fully known. Recent evidence suggests that aquaporin (AQP) water channels play critical roles in protecting cells from osmotic damage during freezing and desiccation. Our study sequenced, functionally characterized and measured the tissue abundance of an AQP from freeze-tolerant larvae of the gall fly, Eurosta solidaginis (Diptera: Tephritidae). The newly characterized EsAQP1 contains two NPA motifs and six transmembrane regions, and is phylogenetically related to an AQP from the anhydrobiotic chironomid Polypedilum vanderplanki. Using a Xenopus laevis oocyte swelling assay, we demonstrated that EsAQP1 increases water permeability to nine times that of simple diffusion through the membrane. In contrast to its high water permeability, EsAQP1 was impermeable to both glycerol and urea. The abundance of EsAQP1 increased from October to December in all tissues tested and was most abundant in the brain of winter larvae. Because the nervous system is thought to be the primary site of freezing injury, EsAQP1 may cryoprotect the brain from damage associated with water imbalance. The sequence, phylogenetic relationship, osmotic permeability, tissue distribution and seasonal abundance of EsAQP1 further support the role of AQPs in promoting freezing tolerance. © 2011.

Wendell Wallach and Colin Allen have authored a book titled 'Moral Machines: Teaching Robots Right from Wrong', which examines a wide range of theoretical and practical questions affecting AMAs (artificial moral agent). In Chapter 1, the authors describe the criteria essential for something to be a good AMA. In Chapter 2, Wallach and Allen draw an important distinction between operational morality and functional morality, which they also contrast with full-blown moral agency. Also in Chapter 2, Wallach and Allen draw an important distinction between reasoning about ethics and ethical decision making. Chapter 3 considers the question of whether humans want computers to make moral decisions, and it also asks whether AMAs could lead humans to abdicate responsibility to machines. In Chapter 4, Wallach and Allen question whether artificial agents (AAs) can be genuine moral agents, especially if AAs lack critical human qualities.

Hypersonic flows of argon, nitrogen, oxygen, and carbon dioxide near a toroidal ballute have been investigated numerically using the Direct Simulation Monte-Carlo (DSMC) technique under transition rarefied-gas flow conditions (Knudsen numbers from 0.005 to 10). Strong influences of the geometrical factor (a ratio of the distance between the axis of symmetry and the torus disk center, and the torus radius) and the Knudsen number on the flow structure (the shape of shock waves and the stagnation point location), skin friction, pressure distribution, and drag have been found. © 2010 by the International Council of Aeronautical Sciences - ICAS.

The discovery of RNAi, in which double-stranded RNA (dsRNA) suppresses the translation of homologous mRNA, has had a huge impact on evolutionary genetics by enabling the analysis of loss-of-function phenotypes in organisms in which classical genetic analysis is laborious or impossible. In this chapter, we discuss an RNAi method via simple dsRNA injection in the red flour beetle, Tribolium castaneum. Tribolium is gaining popularity in evolutionary genetics due in part to the ease of RNAi application. We describe procedures for dsRNA synthesis and injection and provide a description of the injection apparatus. In addition, we detail two methods to validate the efficacy of RNAi (real-time PCR and western blot analyses). Although this chapter focuses mainly on Tribolium, many of the molecular biology and injection procedures described here are applicable to other organisms with some modifications. A few notes regarding dsRNA injection in other species are also included.

The problem of redistribution of translational and rotational energy has been solved for diatomic gases within the framework of the Chapman-Enskog method and the Parker model in the general case of the arbitrary energy exchange ratio. The nonequilibrium gasdynamic equations, transport coefficients and relaxation time have been found for rotational-translational processes in a diatomic gas. The calculations of relaxation time, viscosity, thermal conductivity, and diffusion coefficients are carried out in the temperature range from 200 K to 10,000 K for nitrogen. The calculated parameters and coefficients are compared with the values obtained by the Mason-Monchick approximate method as well as data from experiments in ultrasonic, shock-wave, and vacuum devices. The correlation of the theoretical and experimental data is satisfactory. The applicability of one- and two-temperature relaxation models is discussed. The numerical solutions of the obtained system of the Navier-Stokes equations are analyzed for the cases of nitrogen flow in underexpanded jets and supersonic rarefied gas flow near a sphere. © 2011 American Institute of Physics.

The Direct Simulation Monte-Carlo (DSMC) technique is used for numerical analysis of rarefied-gas hypersonic flows near a blunt plate, wedge, two side-by-side plates, disk, torus, and rotating cylinder. The role of various similarity parameters (Knudsen and Mach numbers, geometrical and temperature factors, specific heat ratios, and others) in aerodynamics of the probes is studied. Important kinetic effects that are specific for the transition flow regime have been found: non-monotonic lift and drag of plates, strong repulsive force between side-by-side plates and cylinders, dependence of drag on torus radii ratio, and the reverse Magnus effect on the lift of a rotating cylinder. The numerical results are in a good agreement with experimental data, which were obtained in a vacuum chamber at low and moderate Knudsen numbers from 0.01 to 10. © 2011 American Institute of Physics.
