Terminal Security Configuration Optimization under Edge Computing

Journal of Physics: Conference Series, 2020
Abstract It is an important task of system security management to configure terminal security policy reasonably in edge computing (EC) to implement necessary security protection for terminals and EC system. Therefore, this paper analyses the security goals and requirements of terminal access for multi-service EC systems under the power ...

Role of hydroxylation for the atomic structure of a non-polar vicinal zinc oxide

Communications Chemistry, 2021
Under-coordinated corner and edge sites often dictate oxide properties, however, information about their atomic-scale structure and chemical nature is often missing. Here, a combined experimental and theoretical study of the ZnO( $$10\bar{1}4$$ 10 1 ¯ 4 )

Self-Termination of Borophene Edges

JACS Au
Due to boron's unique bonding nature, planar boron materials, including borophenes, boron nanoclusters, and nanoribbons, show very puzzling features, especially the superior stability of the free-standing planar boron edges. Here, we present a systematic investigation of the bonding configurations of various edges of borophene.

Cycle-based formulations in Distance Geometry

Open Journal of Mathematical Optimization, 2023
The distance geometry problem asks to find a realization of a given simple edge-weighted graph in a Euclidean space of given dimension $K$, where the edges are realized as straight segments of lengths equal (or as close as possible) to the edge weights ...

Edge state on hydrogen-terminated graphite edges investigated by scanning tunneling microscopy [PDF]

Physical Review B, 2006
The edge states that emerge at hydrogen-terminated zigzag edges embedded in dominant armchair edges of graphite are carefully investigated by ultrahigh-vacuum scanning tunneling microscopy (STM) measurements. The edge states at the zigzag edges have different spatial distributions dependent on the $ $- or $ $-site edge carbon atoms.

Impact of Gamma Ray Irradiation on the Blocking Characteristics of Edge Termination on 4H-SiC and a Novel Anti-Ionizing Radiation Technology

IEEE Journal of the Electron Devices Society
The impact of gamma ray irradiation on the blocking characteristics of edge termination on 4H-SiC has been investigated. The dominant mechanism for the degradation of breakdown voltage (VBD) is the trapping of net positive charges in the field oxide (FOX)

Electrical Transport Characteristics of Vertical GaN Schottky-Barrier Diode in Reverse Bias and Its Numerical Simulation

Energies, 2023
We investigated the temperature-dependent reverse characteristics (JR-VR-T) of vertical GaN Schottky-barrier diodes with and without a fluorine-implanted edge termination (ET).

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Local chemical bonding and structural properties in Ti_{3}AlC_{2} MAX phase and Ti_{3}C_{2}T_{x} MXene probed by Ti 1s x-ray absorption spectroscopy

Physical Review Research, 2020
The chemical bonding within the transition-metal carbide materials MAX phase Ti_{3}AlC_{2} and MXene Ti_{3}C_{2}T_{x} is investigated by x-ray absorption near-edge structure (XANES) and extended x-ray absorption fine-structure (EXAFS) spectroscopies. MAX

Geometrical Mesh Improvement Properties of Delaunay Terminal Edge Refinement [PDF]

, 2006
The use of edge based refinement in general, and Delaunay terminal edge refinement in particular are well established for adaptive meshing, but largely on a heuristic basis. In this paper, we present some theoretical results on geometric improvement, and it limitations, for these methods.
