Structural join is the core part of XML queries and has a significant impact on the performance of XML queries, several classical structural join algorithms have been proposed such as Stack-tree join and XR-Tree join. In this paper, we consider to answer the problem of structural join by partitioning. We first extend the relationships between nodes to the relationships between partitions in the...

Abstract We study the Borel summation of Gromov–Witten potential for resolved conifold. The Stokes phenomena associated to this are shown encode Donaldson–Thomas (DT) invariants conifold, having a direct relation Riemann–Hilbert problem formulated by Bridgeland (Invent Math 216(1), 69–124, 2019). There exist distinguished integration contours which reproduces previous proposals non-perturbative...

Abstract Following observations made in a survey campaign along the Lost River Fault (Idaho, USA) 2019, we integrate both original and previously published data to obtain detailed segmentation of fault sections that failed 1983 Borah Peak earthquake (Mw 6.9). The ruptured topographic surface with an oblique-normal faulting mechanism, activating two SW-dipping segments (Thousand Springs Warm Spr...

The energy deposition of the thermonuclear target explosion products in Inertial Confinement Fusion (ICF) reactors, i.e., ion debris and X-rays and the resulting thermal response of first wall materials, is calculated using the computer code ATEN. Models to accurately simulate the ion and X-ray energy deposition and the consequent response of the wall are implemented in the code. Simultaneous m...

The H.266/Versatile Video Coding (VVC) standard poses a great challenge for encoder design due to its high computational complexity and long encoding time. In this paper, the fast partitioning decision of coding blocks is investigated reduce save time VVC intra-frame predictive coding. A algorithm based on gradient structure similarity directional features proposed. First, average four sub-codi...

In this study, based on the numerical simulation , we investigated aerosol pollution diffusion in residential bathroom with exhaust vents at different positions and ventilation methods. The results show that setting an air outlet under side wall next to toilet can discharge pollutants time which not only shortens path of but also optimizes organization form. dry wet separation area wash separat...

To understand the seismic damage characteristics of bottom frame-wall buildings and to study their seismic performance, the seismic damage outcomes of  bottom frame-wall structures in Du jiang weir by the Wen chuan earthquake on May 12,2008, China were field observed and studied. The assesment of the seismic damage to the bottom frame-wall masonry in Du jiang weir urban showed that the damage t...
