L ike a parachute jump, mitosis can go badly wrong unless every connection is sound. The repetitive DNA sequences located at centromeres help secure mitotic links, Bassett et al. show (1). Contradicting previous evidence that the sequences are expendable, the study indicates that they help attract proteins necessary to repair faulty chromosome connections. Centromeres ensure that mitotic spindl...

The application of automatic transformation processes during the formal development and optimization of programs can introduce encumbrances in the generated code that programmers usually (or presumably) do not write. An example is the introduction of redundant arguments in the functions defined in the program. Redundancy of a parameter means that replacing it by any expression does not change t...

CliniCal MediCine insights: PediatriCs 2016:10 In mid-2015 it was brought to our attention that an article published in 2009,1 Surgery for idiopathic scoliosis: currently applied techniques, Clinical Medicine: Pediatrics 2009;3:39–44, contained redundancies when compared with an earlier article published in Scoliosis,2 titled Surgical treatment of scoliosis: a review of techniques currently app...

Shrinkage is a well known and appealing denoising technique. The use of shrinkage is known to be optimal for Gaussian white noise, provided that the sparsity on the signal’s representation is enforced using a unitary transform. Still, shrinkage is also practiced successfully with non-unitary, and even redundant representations. In this paper we shed some light on this behavior. We show that sim...

Editorial Redundant or duplicate publication is the republishing of a previously published paper in another journal. Such activity violates publishing ethics. This is because originality is a fundamental factor in a scientific paper. Up until 2006, redundant publication had not been uncommon in the medical community, and it was a usual practice among many South Korean authors to republish paper...

The Region Connection Calculus (RCC) [41] is a well-known calculus for representing part-whole and topological relations. It plays an important role in qualitative spatial reasoning, geographical information science, and ontology. The computational complexity of reasoning with RCC5 and RCC8 (two fragments of RCC) as well as other qualitative spatial/temporal calculi has been investigated in dep...

is for the most part identical to an article by Jong Chul Kim, entitled " CT features of bladder small cell carcinoma " published in Clinical Imaging (2004;28:201-205). The corresponding author (JC Kim) has been contacted and has agreed that the two studies are the same.

All members of the ethical committee on publication of the Korean Radiological Society agreed that the two papers belong to the category of redundant publication.

We describe a time-e cient procedure for removing sequentially redundant faults from synchronous sequential circuits with synchronizing sequences. We use properties of redundant faults and propose several methods to identify subsets of redundant faults that can be removed simultaneously from the circuit. By removing several redundant faults simultaneously, the number of repetitions of the test ...

BACKGROUND For patients with senile ptosis, aesthetic blepharoplasty can be combined with ptosis surgery. However, the amount of skin excision necessary in blepharoplasty is not clearly defined by measurements of the upper eyelids. OBJECTIVES The authors preoperatively evaluate the amount of skin to be excised in blepharoplasty. METHODS Fifty patients with bilateral senile ptosis were inclu...
