Mohr and Henderson have presented new algorithms for arc and path consistency in [1]. Though the underlying ideas of their algorithms are correct, the path consistency algorithm PC-3 is in error. In this paper we point out the errors in this algorithm and give a correct one. The time complexity and space complexity of the revised algorithm are also analyzed.

Most weak memory consistency models are incapable of supporting a solution to mutual exclusion using only read and write operations. Processor Consistency–Goodman’s version is an exception. Ahamad et al.[1] showed that Peterson’s mutual exclusion algorithm is correct for PC-G, but Lamport’s bakery algorithm is not. In this paper, we derive a lower bound on the number and type (singleor multi-wr...

We suggest that the conventional need for overwhelming amounts of astrophysical dark matter should be regarded as a warning to standard gravity rather than as merely a challenge to it, and show that the systematics of galactic rotation curve data can just as readily point in the direction of the equally covariant conformal gravity alternative. In particular we identify an apparent imprint of th...

The effects of eritadenine, a constituent of the Lentinus edodes mushroom, and ethanolamine, the base constituent of phosphatidylethanolamine (PE), on fatty acid desaturase activities and lipid profiles were investigated comparatively in rats. Rats were fed a control diet or a diet supplemented with either eritadenine (0.05 g/kg) or ethanolamine (8 g/kg) for 14 d. Eritadenine and ethanolamine h...

ABSTRACT We investigate the presence of hub-filament systems in a large sample 146 active proto-clusters, using H13CO+ J = 1-0 molecular line data obtained from ATOMS survey. find that filaments are ubiquitous and very common dense core scales (?0.1 pc) to clump/cloud (?1–10 pc). The proportion proto-clusters containing decreases with increasing dust temperature (Td) luminosity-to-mass ratios (...

BACKGROUND Palliative care (PC) is no longer offered with preference to cancer patients (CA), but also to patients with non-malignant, progressive diseases. Taking current death statistics into account, PC in Europe will face a growing number of patients dying from non-cancer diseases (NCA). More insights into specialized palliative home care (SPHC) in NCAs are needed. METHODS Retrospective a...

PURPOSE Accurate detection of clinically significant prostate cancer (PC) and correct risk attribution are essential to individually counsel men with PC. Multiparametric MRI (mpMRI) facilitates correct localization of index lesions within the prostate and MRI-targeted prostate biopsy (TPB) helps to avoid the shortcomings of conventional biopsy such as false-negative results or underdiagnosis of...

The ordinary Portland cement (PC) manufacturing process emits toxic carbon dioxide into the environment. Minimizing consumption in construction industry is a major scholarly priority. This paper studies comparison of reinforced concrete and geopolymer beams, which rice husk ash (RHA) used as partial replacement for cement. study aims to determine optimum mix proportion with RHA (PC-RHA) (GC-RHA...
