background : retakes of intra oral radiographs happen frequently in dental practice although radiographic courses train dental students in consecutive semesters. to reduce the patient exposure as much as possible it is mandatory to reduce the number of retakes both in radiology clinics and educational centers. materials and methods : 3188 periapical radiographs taken by bisect-angle technique w...

Background: Male infertility is a Multifactorial syndrome encompassing a wide variety of disorders. In more than half of infertile men, the cause of their infertility is unknown (idiopathic) and could be congenital or acquired. Globozoospermia, also called round-headed spermatozoa, is a rare disease with incidence< 0.1% among male infertile patients. The most prominent feature of globozoospermi...

Background: Successful IVF process is limited by factors such as oocyte quality. Oocyte quality can be defined as its abilities to be fertilized, mature and give rise to normal offspring and it is dependent on nuclear maturation and cytoplasm maturation. Damage to mitochondrial DNA (mtDNA) has been described in oocytes in IVF failure women that decrease cytoplasmic quality because Mitochondria ...

Taking a test has been shown to produce enhanced retention of the retrieved information. On tests, however, students often encounter questions the answers for which they are unsure. Should they guess anyway, even if they are likely to answer incorrectly? Or are errors engrained, impairing subsequent learning of the correct answer? We sought to answer this question in 3 experiments. In Experimen...

Error correction in automatic speech recognition (ASR) aims to correct those incorrect words sentences generated by ASR models. Since recent models usually have low word error rate (WER), avoid affecting originally tokens, should only modify words, and therefore detecting is important for correction. Previous works on either implicitly detect through target-source attention or CTC (connectionis...

Incorrect knowledge can be a problem for any intelligent system. Soar is a proposal for the underlying architecture that supports intelligence. It has a single representation of long-term memory and a single learning mechanism called chunking. This paper investigates the problem of recovery from incorrect knowledge in Soar. Recovery is problematic in Soar because of the simplicity of chunking: ...
