    In:  Supplement to: Kluger, Max Oke; Moon, Vicki G; Kreiter, Stefan; Lowe, David J; Churchman, G J; Hepp, Daniel A; Seibel, David; Jorat, Ehsan M; Mörz, Tobias (2017): A new attraction-detachment model for explaining flow sliding in clay-rich tephras. Geology, 45(2), 131-134, https://doi.org/10.1130/G38560.1
    Publication Date: 2020-01-17
    Description: Altered pyroclastic (tephra) deposits are highly susceptible to landsliding, leading to fatalities and property damage every year. Halloysite, a low-activity clay mineral, is commonly associated with landslide-prone layers within altered tephra successions, especially in deposits with high sensitivity, which describes the post-failure strength loss. However, the precise role of halloysite in the development of sensitivity, and thus in sudden and unpredictable landsliding, is unknown. Here we show that an abundance of mushroom cap?shaped (MCS) spheroidal halloysite governs the development of sensitivity, and hence proneness to landsliding, in altered rhyolitic tephras, North Island, New Zealand. We found that a highly sensitive layer, which was involved in a flow slide, has a remarkably high content of aggregated MCS spheroids with substantial openings on one side. We suggest that short-range electrostatic and van der Waals interactions enabled the MCS spheroids to form interconnected aggregates by attraction between the edges of numerous paired silanol and aluminol sheets that are exposed in the openings and the convex silanol faces on the exterior surfaces of adjacent MCS spheroids. If these weak attractions are overcome during slope failure, multiple, weakly attracted MCS spheroids can be separated from one another, and the prevailing repulsion between exterior MCS surfaces results in a low remolded shear strength, a high sensitivity, and a high propensity for flow sliding. The evidence indicates that the attraction-detachment model explains the high sensitivity and contributes to an improved understanding of the mechanisms of flow sliding in sensitive, altered tephras rich in spheroidal halloysite.

    Notes: Summary Estradiol-17β and progesterone at physiological concentrations in vivo induced a reduction in lysosomal stability in the digestive cells of Mytilus edulis. Estradiol-17β (10−8 M) also reduced lysosomal stability within 15min in vitro. Lysosomal stability was determined cytochemically as the labilisation period for latent N-acetyl-β-hexosaminidase and this was shown to be inversely related to microdensitometric measurements of staining intensity for this enzyme. Estradiol-17β did not appear to induce complete labilisation or cytochemical activation of lysosomal hexosaminidase and a second, much longer labilisation period could be determined for this hormone. The effects of estradiol-17β were partially counteracted by cortisol (10−2 M). There was an increase in PAS staining of secondary lysosomes and an increase in alcian blue staining of residual bodies in digestive cells of animals exposed to estradiol-17β, while no changes could be observed in basophil cells. The significance of these results is discussed in terms of the physiological role of digestive cells and their possible function as target cells for estradiol-17β and progesterone.

    Notes: Abstract Systemic clearance of atrial natriuretic peptide (ANP) is in part due to neutral endopeptidase (NEP) proteolysis and natriuretic peptide receptor-C (NPR-C) mediated endocytosis. Biological responses to ANP are primarily mediated by the membrane guanylyl cyclase-A/natriuretic peptide receptor-A (NPR-A). Analogs of ANP selective for NPR-A and/or resistant to NEP may have increased activity in those tissues where NPR-C and NEP are coexpressed with NPR-A. The analog of ANP termed vANP; [(R3D, G9T, R11S, M12L, G16R)ANP] is selective for human NPR-A with at least 10,000 fold reduction in affinity for human NPR-C. We report that rat NPR-A is insensitive to 10 nM vANP, demonstrating the limitations of this species in evaluating human therapeutic candidates. As an alternative approach we tested the binding and potency of receptor-selective and NEP-resistant ANP analogs in rhesus monkey tissues. Competition binding studies with a simplified version of vANP, sANP [(G9T, R11S, G16R)rANP], in rhesus monkey kidney and lung membrane preparations shows displacement of 125I-ANP from only a fraction of the total ANP receptor population, 30 and 85%, respectively. The remaining ANP binding sites can be occupied with the NPR-C selective ligand cANP(4-23). These data strongly suggest that only two classes of ANP receptor are present in these membrane preparations, NPR-A and NPR-C. The NEP resistant sANP derivative called sANP(TAPR) was 8 fold more potent (ED50 = 0.6 nM) than rANP (ED50 = SnM) in stimulating cGMP production in the lung membrane preparation. Our results demonstrate that the rhesus monkey natriuretic peptide receptors reflect the pharmacology of the human receptors, and that this species may be suitable to determine the role of NPR-C and NEP in peptide clearance and attenuating functional responses.

    Notes: Abstract In this paper we show, for the first time, how Radial Basis Function (RBF) network techniques can be used to explore questions surrounding authorship of historic documents. The paper illustrates the technical and practical aspects of RBF's, using data extracted from works written in the early 17th century by William Shakespeare and his contemporary John Fletcher. We also present benchmark comparisons with other standard techniques for contrast and comparison.

    Notes: Abstract While edge detection is an important first step for many vision systems, the linked lists of edge points produced by most existing edge detectors lack the higher level of curve description needed for many visual tasks. For example, they do not specify the tangent direction or curvature of an edge or the locations of tangent discontinuities. In this paper, a method is presented for describing linked edge points at a range of scales by selecting intervals of the curve and scales of smoothing that are most likely to represent the underlying structure of the scene. This multiscale analysis of curves is complementary to any multiscale detection of the original edge points. A solution is presented for the problem of shrinkage of curves during Gaussian smoothing, which has been a significant impediment to the use of smoothing for practical curve description. The curve segmentation method is based on a measure of smoothness minimizing the third derivative of Gaussian convolution. The smoothness measure is used to identify discontinuities of curve tangents simultaneously with selecting the appropriate scale of smoothing. The averaging of point locations during smoothing provides for accurate subpixel curve localization. This curve-description method can be implemented efficiently and should prove practical for a wide range of applications including correspondence matching, perceptual grouping, and model-based recognition.
