Summary: Mechanical stratigraphy plays a crucial role in the growth of normal faults, controlling their geometry and kinematics. This study examines normal faults formed in a deep-water clastic succession offshore Angola, and finds that the presence of a mass-transport complex (MTC) influences the growth patterns of the faults. Faults that offset the MTC have greater throw and propagate downward, while faults that terminate at the MTC have smaller throw. These findings highlight the significant control of mechanical stratigraphy on fault development.

Summary: The study uses high-resolution 3D seismic and borehole data in the Broad Fourteens Basin of the Southern North Sea to investigate the relationship between lithology and fault throw distribution, as well as to understand the reactivation and growth histories of faults developed due to tectonic inversion. Two distinct tiers of faults are identified, and their geometry is analyzed in detail.

Summary: Fault damage zones play a dominant role in the mechanical, hydraulic and seismological properties of faults. This study investigates the development of damage related to slip on rough faults and earthquake ruptures. The results suggest that the extent and distribution of damage are influenced by fault roughness, slip amount and dynamic rupture characteristics.

Summary: The aspect ratio of filler particles significantly affects the mechanical properties of particle-reinforced polymer composites, with increasing aspect ratio and concentration leading to higher elastic and dynamic moduli. However, beyond a certain particle loading threshold, these properties start to decrease. The mechanical reinforcement in the system mainly comes from efficient load transfer between particles and the matrix in the particle orienting direction, as shown by the failure of the percolation model and the Cox model to adequately fit the data. The thermal stability of the composite films is enhanced with the addition of MOF particles due to their high thermal degradation temperature and restricted polymer chain mobility.

Summary: This paper proposes an impedance-based scheme for discrimination between faults at the end of the line and adjacent line faults, accelerating the operation of distance relays zone-2. The algorithm is independent of external factors and accurately identifies fault locations, achieving precise fault location under various simulation conditions.

Summary: This study compares the relationship between earthquake magnitude and rupture length to assess the hazard of active faults, providing recommendations for seismic hazard modeling in Indonesia. It suggests considering different weighting between published earthquake scaling relationships when constructing a logic tree for seismic hazard modeling.

Summary: Research indicates that spherical tokamaks offer a faster, more economical, and more compact solution compared to large aspect ratio tokamaks. However, plasma studies on compact, low aspect ratio tokamaks have been limited so far, restricting the data available for extrapolating to large scale ST plasmas.

Summary: This study investigates the vertical and horizontal displacement transfer mechanisms across a relay zone adjacent to the Moab Fault. Photogrammetry and 3D modeling techniques were used to analyze the relay-bounding faults and subordinate faults within the relay zone. It was found that horizontal displacement transfer occurs through a shallow dipping relay ramp, while vertical displacement transfer is facilitated by antithetic faults within the relay ramp.

Summary: This study theoretically analyzes the effects of orientation angles and aspect ratios of nanofiber fillers on the breakdown behavior and dielectric properties of composites. The results show that a higher inclination of the nanofiber fillers leads to a higher nominal breakdown strength, due to obstruction of conductive channels. However, the dielectric constant shows an opposite trend. Additionally, a higher aspect ratio of the nanofiber fillers helps achieve a higher breakdown strength with a slight sacrifice of the dielectric constant.

Summary: SiC particle and SiC whisker-reinforced Cu composites were prepared using pulse intermittent deposition and spark plasma sintering. The formation of core-shell structures solved the agglomeration problem and increased the bonding strength of the interface. The Cu-coated SICW exhibited significantly higher strength, plasticity, and thermal conductivity, and the externally applied load was effectively transferred. This study provides an advanced approach for designing high-performance metal-matrix composites with tailored aspect ratios of discontinuous second phases.

Summary: This study estimates the seismic site response in the Binchuan basin in Yunnan Province, Southwest China using data from a dense linear array of seismometers. The results show that earthquakes with larger epicentral distances produce stronger spatial variability in peak ground velocity (PGV). The PGV values are overall larger in the middle of the array than the two sides, especially in the horizontal directions. The study also finds that ground motions inside the low-velocity zone (LVZ) are up to 20 times larger than outside, and a more localized zone enclosing the fault surface trace has larger factors of amplification.

Summary: In this study, the effect of bacterial cellulose nanocrystals (BCNCs) with different aspect ratios on the properties of sodium alginate (SA) films was investigated. It was found that BCNCs with higher aspect ratios were more effective in enhancing the Young's modulus of the films. However, the reinforcing efficiency decreased as the BCNC concentration increased.

Summary: This study investigates the hydrodynamic characteristics of an elastically-mounted elliptic cylinder at low mass and damping ratios. The results show that the streamlined profile of the cylinder delays vortex shedding and reduces vorticity. However, the hydrodynamic characteristics become more complicated for larger aspect ratios.
