TL;DR: In this paper, a landslide database and distribution map was constructed using historical records, satellite images, field investigations and unmanned aerial vehicle (UAV) observations, enabling the construction of a complete landslide database, and three failure modes of landslides in the Zigui basin were used to illustrate the major factors that govern reservoir-induced landslides.

TL;DR: In this paper, a Monte Carlo simulation-based numerical model of site exploration is established to generate artificial test data, and a series of parametric analyses are performed to investigate the relationship between the level of exploration effort and the accuracy of the tunneling-induced ground settlement prediction.

TL;DR: In this article, the influence of the stratigraphic uncertainty on the behavior of the geotechnical system and its design is analyzed in a bi-objective optimization-based problem that considers the design safety and the cost simultaneously.

TL;DR: In this article, a new framework for the probabilistic analysis of tunnel longitudinal performance is presented, where the conditional random field theory is adopted to simulate the spatial variation of soil properties along the tunnel longitudinal direction, in which the soil properties at borehole locations can be explicitly considered.

TL;DR: All the progress made over the last 20 years on this topic are reviewed, including the breaking of the old dichotomy between “acute” and “chronic” Q fever and the achievement of determining the genome sequences of several strains of this species and comparative genomic analyses.
Abstract: Coxiella burnetii is the agent of Q fever, or ``query fever,'' a zoonosis first described in Australia in 1937. Since this first description, knowledge about this pathogen and its associated infections has increased dramatically. We review here all the progress made over the last 20 years on this topic. C. burnetii is classically a strict intracellular, Gram-negative bacterium. However, a major step in the characterization of this pathogen was achieved by the establishment of its axenic culture. C. burnetii infects a wide range of animals, from arthropods to humans. The genetic determinants of virulence are now better known, thanks to the achievement of determining the genome sequences of several strains of this species and comparative genomic analyses. Q fever can be found worldwide, but the epidemiological features of this disease vary according to the geographic area considered, including situations where it is endemic or hyperendemic, and the occurrence of large epidemic outbreaks. In recent years, a major breakthrough in the understanding of the natural history of human infection with C. burnetii was the breaking of the old dichotomy between ``acute'' and ``chronic'' Q fever. The clinical presentation of C. burnetii infection depends on both the virulence of the infecting C. burnetii strain and specific risks factors in the infected patient. Moreover, no persistent infection can exist without a focus of infection. This paradigm change should allow better diagnosis and management of primary infection and long-term complications in patients with C. burnetii infection.

TL;DR: In this paper, the authors studied the problem of feedback stabilization over a signal-to-noise ratio (SNR) constrained channel and showed that for either state feedback, or for output feedback delay-free, minimum phase plants, there are limitations on the ability to stabilize an unstable plant over an SNR constrained channel.
Abstract: There has recently been significant interest in feedback stabilization problems over communication channels, including several with bit rate limited feedback. Motivated by considering one source of such bit rate limits, we study the problem of stabilization over a signal-to-noise ratio (SNR) constrained channel. We discuss both continuous and discrete time cases, and show that for either state feedback, or for output feedback delay-free, minimum phase plants, there are limitations on the ability to stabilize an unstable plant over an SNR constrained channel. These limitations in fact match precisely those that might have been inferred by considering the associated ideal Shannon capacity bit rate over the same channel.

TL;DR: An extensive analysis and comparison between different ML techniques using a case study from Algeria is undertaken, noting that tree-based ensemble algorithms achieve excellent results compared to other machine learning algorithms and that the Random Forest algorithm offers robust performance for accurate landslide susceptibility mapping with only a small number of adjustments required before training the model.
