New York University mathematical physicist Alan Sokal published in the postmodern humanities journal Social Text a parody entitled “Transgressing the Boundaries: Toward a Transformative Hermeneutics of Quantum Gravity” [1]. His point in doing so was to test whether the field of “cultural studies of science” was seriously lacking in “intellectual standards”. His article is nonsense from start to...

To cite: Sahni VA, Khorasani R. BMJ Qual Saf 2016;25:569–571. Diagnostic errors in radiology reports can result in patient harm, lead to unnecessary additional testing or interventions, or otherwise diminish the quality of care delivery. 2 In this issue, Lauritzen et al retrospectively evaluated the impact of a quality assurance process using double reads on changes made to abdominal CT reports...

abstract         sasanian dynasty, who governed as the last and the most glorious dynasty before islam in iran, has had an important role in enrichment of sasanian silver works and we owe the majority of silver works to this era. metalwork is one of the oldest arts iniranian civilization. the prominent metalwork crafts‚ left from different ages‚ acknowledge this fact. the art of this era has di...

Proper visualization of scientific data is important for understanding spatial relationships. Particularly in the field of structural biology, where researchers seek to gain an understanding of the structure and function of biological macromolecules, it is important to have access to visualization programs which are fast, flexible, and customizable. We present KiNG, a Java program for visualizi...

We propose a new method to correct short reads using de Bruijn graphs, and implement it as a tool called Bcool. As a first step, Bcool constructs a corrected compacted de Bruijn graph from the reads. This graph is then used as a reference and the reads are corrected according to their mapping on the graph. We show that this approach yields a better correction than kmer-spectrum techniques, whil...

The wide applications of next-generation sequencing (NGS) technologies in metagenomics have raised many computational challenges. One of the essential problems in metagenomics is to estimate the taxonomic composition of a microbial community, which can be approached by mapping shotgun reads acquired from the community to previously characterized microbial genomes followed by quantity profiling ...
