Abstract—In this letter, a flexible memory simulator - NVMain 2.0, is introduced to help the community for modeling not only commodity DRAMs but also emerging memory technologies, such as die-stacked DRAM caches, non-volatile memories (e.g., STT-RAM, PCRAM, and ReRAM) including multi-level cells (MLC), and hybrid non-volatile plus DRAM memory systems. Compared to existing memory simulators, N…
This paper analyzes the motion planning of a custom-built all position autonomous mobile welding robot. It proposes a novel motion planning method that allows the robot to complete fillet seamwelding while the vehicle turns around the right angle seam simultaneously. The global optimal solution is obtained through model modification. Note to Practitioners—This paper ismotivated by the proble…
Abstract. In this work, a novel macro–microporous architecture is successfully constructed in a honeycomb-like structure by directly using rape seed shell via impregation-activation route. This approach permits the high specific surface area (SSA) and a unique hierarchical porous structure which consists of interconnected macroporous skeleton and a significant microporosity. The unique ho…
Abstract Silica nanowires were synthesized through a selfsupplied vapor–liquid–solid (VLS) mechanism. Unlike randomly entangled nanowires on the substrate, highly ordered nanowire arrays have been successfully fabricated using a sandwich-like configuration to define and enhance the local gas-flow. As-synthesized nanowires were characterized to be amorphous silicon dioxide with Au as cata…
A general two-step approach has been developed for the synthesis of very small and sintering-resistant bimetallic gold-silver nanoparticles on inert supports including commercial silica and alumina. In this approach, gold particles were formed in the first step on amino-functionalized silica or alumina support. Our density functional theory (DFT) calculations on selected model clusters show …
In the large Cucurbitaceae genus Cucumis, cucumber (C. sativus) is the only species with 2n = 2x = 14 chromosomes. The majority of the remaining species, including melon (C. melo) and the sister species of cucumber, C. hystrix, have 2n = 2x = 24 chromosomes, implying a reduction from n = 12 to n = 7. To understand the underlying mechanisms, we investigated chromosome synteny among cucumber, C.…
