Spatiotemporal Landslide Activity Derived from Tree-rings: The Tieliku Mingsui Landslide, Northern Taiwan
Spatiotemporal landslide activity records are reconstructed for the Tieliku Mingsui landslide. Periods and the extent of scar activity at the foot of the landslide body are estimated from satellite and aerial photo records. The location of landslide features at the densely forested head of the landslide body are surveyed in the field using a VBS-RTK survey and periods of activity are inferred from growth disturbances recorded in 14 conifer and broadleaf trees growing adjacent to the features. Together, image and growth disturbance records produce a detailed spatiotemporal landslide activity record that spans 34 years and includes 8 years of activity. A comparison of landslide activity records with rainfall data collected near the landslide reveals that years of landslide activity coincide with years of high summer season and event accumulated rainfall

Paper-Based Microfluidics for Disease Diagnostics
Accurate diagnosis is the most important step in identifying and curing diseases. There are no accurate low cost disease diagnostic tools available for developing countries. The use of microfluidic paper-based analytical devices and colorimetric analysis of an assay response could solve these issues. Several colorimetric liver assays have been demonstrated to have linear standard curves, covering the diagnostically relevant range of analyte concentrations, when printed on paper.
A digital component is also presented to increase point-of-care assay throughput, diagnostic accuracy, and seamless data handling. The use of the HP Cloud provides novel uses of aggregate non-identifying health information for epidemiological studies
The Full Event Interpretation -- An exclusive tagging algorithm for the Belle II experiment
The Full Event Interpretation is presented: a new exclusive tagging algorithm
used by the high-energy physics experiment Belle II. The experimental setup of
Belle II allows the precise measurement of otherwise inaccessible meson
decay-modes. The Full Event Interpretation algorithm enables many of these
measurements. The algorithm relies on machine learning to automatically
identify plausible meson decay chains based on the data recorded by the
detector. Compared to similar algorithms employed by previous experiments, the
Full Event Interpretation provides a greater efficiency, yielding a larger
effective sample size usable in the measurement.Comment: 11 pages, 7 figures, 1 tabl
Diasporas and secessionist conflicts : the mobilization of the Armenian, Albanian and Chechen diasporas
This article examines the impact of diasporas on secessionist conflicts, focusing on the Albanian, Armenian and Chechen diasporas and the conflicts in Kosovo, Karabakh and Chechnya during the 1990s. How do diasporas radicalize these conflicts? I argue that despite differences in diaspora communal characteristics and the types of the secessionist conflicts, a common pattern of mobilization develops. Large-scale diasporic support for secessionism emerges only after independence is proclaimed by the local elites. From that point onwards diasporas become engaged in a conflict spiral, and transnational coalitions are formed between local secessionist and diaspora groups. Depending on the organizational strength of the local strategic centre and the diasporic institutions, these coalitions endure or dissipate. Diasporas exert radicalization influences on the conflict spiral on two specific junctures â when grave violations of human rights occur in the homeland and when local moderate elites start losing credibility that they can achieve the secessionist goal

Activinâlike kinaseâ3 activity is important for kidney regeneration and reversal of fibrosis
Molecules associated with TGF-β superfamily such as BMPs and TGF-β are key regulators of inflammation, apoptosis and cellular transitions. Here, we demonstrate that the BMP receptor activinâlike kinase 3 (Alk3) is elevated early in response to kidney injury and its deletion in the tubular epithelium leads to enhanced TGF-β1 / Smad3 signaling, epithelial damage and fibrosis, suggesting a protective role for Alk3 mediated signaling. Structureâfunction analysis of Alk3 / BMP / BMPRII ligandâreceptor complex coupled with synthetic organic chemistry led us to construct a library of small peptide agonists of BMP signaling that function via Alk3 receptor. One such peptide agonist, THRâ123, suppressed inflammation, apoptosis epithelialâtoâmesenchymal transition program, and reversed fibrosis in mouse models of acute and chronic injury. Combining THRâ123 and angiotensinâconverting enzyme inhibitor, captopril, exhibited additive therapeutic benefit in controlling fibrosis. Our studies demonstrate that BMP signaling agonists constitute a new line of therapeutic agents with a potential utility in the clinic to induce regeneration, repair and reverse fibrosis
Breed differences in development of anti-insulin antibodies in diabetic dogs and investigation of the role of dog leukocyte antigen (DLA) genes
Administration of insulin for treatment of diabetes mellitus in dogs can stimulate an immune response, with a proportion of animals developing anti-insulin antibodies (AIA). For an IgG antibody response to occur, this would require B cell presentation of insulin peptides by major histocompatibility complex (MHC) class II molecules, encoded by dog leukocyte antigen (DLA) genes, in order to receive T-cell help for class switching. DLA genes are highly polymorphic in the dog population and vary from breed to breed. The aim of the present study was to evaluate AIA reactivity in diabetic dogs of different breeds and to investigate whether DLA genes influence AIA status.
Indirect ELISA was used to determine serological reactivity to insulin in diabetic dogs, treated with either a porcine or bovine insulin preparation. DLA haplotypes for diabetic dogs were determined by sequence-based typing of DLA-DRB1, -DQA1 and -DQB1 loci. Significantly greater insulin reactivity was seen in treated diabetic dogs (n = 942) compared with non-diabetic dogs (n = 100). Relatively few newly diagnosed diabetic dogs (3/109) were found to be AIA positive, although this provides evidence that insulin autoantibodies might be involved in the pathogenesis of the disease in some cases. Of the diabetic dogs treated with a bovine insulin preparation, 52.3% (182/348) were AIA positive, compared with 12.6% (75/594) of dogs treated with a porcine insulin preparation, suggesting that bovine insulin is more immunogenic. Breeds such as dachshund, Cairn terrier, miniature schnauzer and Tibetan terrier were more likely to develop AIA, whereas cocker spaniels were less likely to develop AIA, compared with crossbreed dogs. In diabetic dogs, DLA haplotype DRB1*0015--DQA1*006--DQB1*023 was associated with being AIA positive, whereas the haplotype DLA-DRB1*006--DQA1*005--DQB1*007 showed an association with being AIA negative. These research findings suggest that DLA genes influence AIA responses in treated diabetic dogs
