Application of IR/SEM and Other Modern Instruments for Mineral Identification
Yankuang ceshi, 2014 Due to the limitations of resolution and magnification for the traditional optical microscope, qualitative analysis for fine particles is inaccurate and quantitative analysis of minerals contains errors, which makes it impossible to obtain accurate nano ...

Convolutional Neural Network for Earthquake Detection and Location [PDF]
arXiv, 2017 The recent evolution of induced seismicity in Central United States calls for exhaustive catalogs to improve seismic hazard assessment. Over the last decades, the volume of seismic data has increased exponentially, creating a need for efficient algorithms to reliably detect and locate earthquakes.

The Anatomical Record, EarlyView.Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Unimodal part of the magnitude-frequency distribution of earthquakes according to the USGS catalog [PDF]
arXiv, 2019 In this paper, we used the Global Catalog of the National Earthquake Information Center US Geological Survey (NEIC USGS) for analysis of the magnitude-frequency distribution of earthquakes. We selected the unimodal part of the distribution and proposed an empirical formula that approximates this part in a wide range of magnitudes.

The Anatomical Record, EarlyView.Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Bayesian Nonparametric Nonhomogeneous Poisson Process with Applications to USGS Earthquake Data [PDF]
arXiv, 2019 Intensity estimation is a common problem in statistical analysis of spatial point pattern data. This paper proposes a nonparametric Bayesian method for estimating the spatial point process intensity based on mixture of finite mixture (MFM) model. MFM approach leads to a consistent estimate of the intensity of spatial point patterns in different areas ...

The Anatomical Record, EarlyView.Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.
