Abstract:
Topological materials with band-crossing points exhibit interesting electronic characteristics and have special applications in electronic devices. However, to further facilitate the experimental detection of the signatures of these band crossings, topological materials with a large linear energy range around the band-crossing points need to be found, which is challenging. Here, via first-principle approaches, we report that the previously prepared P6/mmm-type CrB2 material is a topological metal with one pair of 1D band-crossing points, that is, nodal lines, in the kz= 0 plane, and one pair o

Abstract:
This paper describes a robust algorithm for detecting zebra crossings to provide information for intelligent vehicles’ autonomous navigation in urban environment. First, transform images framed by the camera to the top view by an Inverse Perspective Mapping (IPM); extract the region of interest (ROI) from IPM image by local threshold segmentation. Then, extract datum band from RIO by analysis of every region’s length, direction, as well as mutual relations between the bands; finally, extract all bands belonging to the zebra crossing. The zebra crossing’s distance and direction are easily calcu

Abstract:
The presence of one-dimensional (1D) nodal lines, which are formed by band crossing points along a line in the momentum space of materials, is accompanied by several interesting features. However, in order to facilitate experimental detection of the band crossing point signatures, the materials must possess a large linear energy range around the band crossing points. In this work, we focused on a topological metal, YB2, with phase stability and a P6/mmm space group, and studied the phonon dispersion, electronic structure, and topological nodal line signatures via first principles.

Abstract:
An oriented 2-component link is called band-trivializable, if it can be unknotted by a single band surgery. We consider whether a given 2-component link is band-trivializable or not. Then we can completely determine the band-trivializability for the prime links with up to 9 crossings. We use the signature, the Jones and Q polynomials, and the Arf invariant. Since a band-trivializable link has 4-ball genus zero, we also give a table for the 4-ball genus of the prime links with up to 9 crossings. Furthermore, we give an additional answer to the problem of whether a (2n + 1)-crossing 2-bridge kno

The dilute nitrides on GaAs (e.g. Ga(In)NxAs1-x where typically x < 5%) have provided a large amount of interesting physics and led to the development of improved telecommunication lasers. In the last 5 years, novel dilute nitride materials (such as GaN(As)P) have grown in popularity due to applications such as monolithic growth on silicon and improved device characteristics in red-amber-yellow solid state illumination. The Band Anti-Crossing model, using a single weighted nitrogen level (found through photocurrent spectroscopy), is found to successfully predict the band gap energy in GaNP/GaP

Provided certain conditions are satisfied, the zero crossings of a signal constitute a sampling set. Indeed we have shown that images can be reconstructed from such a set. Considering this or other sampling theorems, two fundamental issues must be addressed. First, the existence of a broad class of signals satisfying the conditions in which recovery is guaranteed, and second, the existence of practical stable reconstruction algorithms. In the case of zero crossing the above conditions are not necessarily satisfied. The sine-wave-crossing (SWC) approach overcomes these difficulties. The theoret

Abstract:
This short pedagogical movie illustrates an effect in nuclear physics called backbending which was first observed in the study of the rotational behavior of rapidly rotating rare-earth nuclei in Stockholm, Sweden in 1971. The video contains a mechanical analog utilizing rare-earth magnets and rotating gyroscopes on a turntable along with some historic spectra and papers associated with this landmark discovery together with its explanation in terms of the Coriolis induced uncoupling and rotational alignment of a specific pair of particles occupying high-j intruder orbitals. Thus backbending rep

Abstract:
This work product aims to develop protocols and approaches for desktop reviews of potential interactive threats as part of a waterway crossing program assessment. This work is currently being performed by pipeline operators and generally consists of the review and analysis of publicly available and operator-provided information (such as aerial imagery, LIDAR data sets, inertial measurement unit (IMU) data, bathymetric surveys, United States Department of Agriculture soil reports, United States Geological Survey geologic maps and hazard mapping, and state agency hazard mapping) to qualitatively

Abstract:
This report discusses the use of Synthetic Aperture Radar (SAR) satellites for monitoring above ground pipelines and buried pipeline Rights-Of-Way (ROWs) using Interferometric Synthetic Aperture Radar (InSAR) techniques. The main thrust of the research was to evaluate the suitability of above-ground pipeline support members as InSAR measurement points, and to adapt existing techniques to allow for precise monitoring of jacking and subsidence caused by permafrost degradation and dynamics. The study site at Prudhoe Bay, Alaska includes more than 60,000 horizontal pipeline supports. The known loc

Abstract:
Evaluating risks for hydrotechnical threats at pipeline waterway crossings is important to maintaining pipeline integrity. Establishing standards and best practices for evaluating the risks associated with scour, bank erosion, and channel avulsion is essential to developing a consistent process that can be applied across a network of pipeline crossings and provide data to make decisions about prioritizing mitigation and monitoring. A multi-step process including inventory, screening, desktop analysis, and site visit can be applied to compile regional and local data from existing sources as wel

The goal of the work described herein is to provide PRCI and the pipeline industry further understanding of the current capabilities and limitations of combined SAR and high resolution optical satellite imagery for the monitoring of pipeline ROWs which span river crossings. Four Areas of Interests (AOIs) with pipeline ROWs that span river crossings were selected for analysis: South Saskatchewan River, Saskatchewan, Canada operated by SaskEnergy Incorporated; Thompson Creek, Louisiana, USA operated by Colonial Pipeline Company; Gila River, Arizona, USA operated by Kinder Morgan Incorporated; an

Abstract:
Flood related channel bed erosion, bank migration, and channel avulsions can represent a significant threat to pipeline integrity. Because there is well over 100,000 miles of liquid petroleum pipelines across the United States, the number of pipeline water crossings at risk from potential flood related forces is equally large. However, the vast majority of these pipeline water crossings are located on small rivers and streams that do not represent a significant threat to pipeline integrity. Conversely, understanding which rivers have the potential to impact pipeline integrity is critical for p
