Graph mining is an important category of graph algorithms that aim to discover structural patterns such as cliques and motifs in a graph. While great deal work has been done recently on computation PageRank, systems support for scalable still limited. Existing Arabesque focus distributed computing need large amounts compute memory resources.We built RStream, the first single-machine, out-of-core system leverages disk store intermediate data. At its core are two innovations: (1) rich...
Abstract Layered silicene with deformed buckled structure attracts great interest as a next generation 2D Dirac thermoelectric material beyond conventional layered materials. However, the difficulty of modulating atomic positions in prevents its realization. This study proposes method to deform by controlling intercalated atoms, which can dramatically enhance properties. Silicene is epitaxial CaSi 2 thin films, Ca‐intercalated silicenes, on Si(111) substrates, related composition Ca....
Abstract We constructed a fuel‐flexible fuel cell consisting of an alkaline anion exchange membrane, palladium anode, and platinum cathode. When alcohol was used with potassium hydroxide added to the stream oxygen oxidant, following maximum power densities were achieved at 60 °C: ethanol (128 mW cm −2 ), 1‐propanol (101 2‐propanol (40 ethylene glycol (117 glycerol (78 propylene (75 ). also observed density 302 when formate as under same conditions. However, removed from stream, decreased 9...
ABSTRACT The health and resilience of the Great Barrier Reef ecosystems are affected by complex dynamics interconnected processes. A systems thinking approach can aid to comprehensively understand past, current future system behaviour, thereby informing effective decision‐making. qualitative conceptual model was developed based on theory critical literature reviews, giving consideration non‐linear feedbacks that determine structure behaviour system. indicates feedback is governed...
Fluoride ion (F − ) contamination of groundwater has become a global issue. As potential adsorbents for F removal, layered double hydroxides (LDHs) have moderate affinities . Moreover, the preparation of...
Abstract The direct formate fuel cell (DFFC) has recently been demonstrated as a viable alkaline liquid (DLFC) that does not require addition of hydroxide to the stream for operation. In this work, we report DFFC can produce significant power at low temperatures without added hydroxide, especially when compared with other DLFCs powered by alcohols. Using oxygen cathode, 1 M HCOOK achieves maximum density 106 mW cm –2 50 °C and 64 23 °C. air same 76 27 These densities were achieved stream....
Wrinkles are unavoidable byproducts of graphene growth during chemical vapor deposition. They form because the different thermal expansion coefficients and underlying substrate. Micrometer-sized wrinkles known to affect electronic properties due their shape strain variations they create. However, as finds more applications in nanoscale devices, it is necessary investigate physical nature nanometer dimensions. Here, we analyze distribution doping a wrinkle having 1.9 nm width using...

This post hoc, exploratory analysis assessed the study’s 2...
The adsorption of nitric oxide (NO) on various metal phthalocyanines (MPc, M = Mn, Fe, Co) has been studied using first-principles calculations based density functional theory (DFT). In this study, we investigated the fully optimized geometries and electronic structure MPc. We found that structures atoms are essential in shaping ground-state near Fermi level. These states defined mostly by d orbitals transition-metal and, to some degree, nitrogen carbon inner rings. numerical showed NO...
Psychological distress is prevalent in patients with cancer, negatively affecting their treatment and quality of life. Clinical guidelines recommended screening all cancer routinely for psychological problems using simple measures such as the Distress Thermometer (DT) Problem List (PL). This study first research Vietnam to identify optimal DT cutoff point screen relationship PL items among patients.300 were recruited from 10 departments at National Cancer Hospital (K hospital) completed PL....

Although they were discovered almost a century ago, atropisomers are only now having their heyday. Uncovered by James Kenner and George Hallatt Christie at the University of Sheffield in 1922, this exotic class chiral compounds revealed itself to duo deceptively simple molecule. The compound, dubbed 6,6′-dinitro-2,2′-diphenic acid, consists two aromatic rings lashed together carbon-carbon bond that is flanked carboxylic acid nitro group jutting from each ring. In typical molecules, linked...
