AIM This study sets out to test the biocompatibility of titanium clips in liver, in the presence of radiofrequency. Biocompatibility is assessed at various distances from the RF electrode and different points in time. METHOD It is an experimental study conducted on pigs and makes use of histological changes that occur at the liver-titanium interface in presence of RF to test hypotheses. The t...

BACKGROUND AND PURPOSE Various laparoscopic devices have been described for suture anchoring during solidorgan parenchymal closure. Application of these devices expedites the closure of parenchymal defects and minimizes ischemia time. We compared different technologies as suture anchors for parenchymal closure. MATERIALS AND METHODS A tensometer was used to determine the amount of tension nec...

Participants listened to words while viewing film clips (audio off). Film clips were classified as neutral, positively valenced, negatively valenced, and arousing. Memory was assessed in three ways: recall of film content, recall of words, and context recognition. In the context recognition test, participants were presented a word and determined which film clip was showing when the word was ori...

PURPOSE We investigated the feasibility of using surgical clips as markers for tumor localization and their effect on the imaging evaluation of treatment responses after neoadjuvant chemotherapy (NAC). METHODS A total of 16 breast cancers confirmed by needle biopsy in 15 patients were included in this study from October 2012 to June 2014. Under ultrasonography (US)-guidance, the surgical clip...

Systems like CLIPS [NASA] addressed this problem in part by defining what is essentially a user callable reasoning library and allowing the library to call user-defined functions or programs. Still, there was a relatively strong separation between the CLIPS knowledge space and the user program's knowledge space. CLIPS knowledge and user program knowledge could not be directly shared and interch...

The speech to song illusion is a perceptual phenomenon where listeners perceive the transformation of certain speech clips into song after approximately ten consecutive repetitions of the clips. Both perceptual and acoustic features of the audio clips have been studied in previous experiments. Though the perceptual effects are clear, the features driving the illusion are only known to relate to...

This paper describes different molecular junctions with different alligator clips connected to gold electrodes at nanometre-scale. Our objective was to determine the charge transport characteristics of these junctions and determine the optimum alligator clip pair. We scrutinised anthracenedithiol (ADT), anthracenediamine (ADA) and anthracenethiolamine (ATA) and computed their conductance parame...

E-learning has acquired a prime place in many discussions recently. A number of research efforts around the world are trying to enhance education and training through improving e-learning facilities. This paper briefly explains one such attempt aimed at designing a system to support video clips in e-learning and explains how profiles of the presenters in video clips can be used to improve the u...
