We prove a relationship between the Cleaning problem and the Balanced Vertex– Ordering problem, namely that the minimum total imbalance of a graph equals twice the brush number of a graph. This equality has consequences for both problems. On one hand, it allows us to prove the NP-completeness of the Cleaning problem, which was conjectured by Messinger et al. [7]. On the other hand, it also enab...

The authors investigated whether anomalous information in the periphery of a scene attracts saccades when the anomaly is not distinctive in its low-level visual properties. Subjects viewed color photographs for 8 s while their eye movements were monitored. Each subject saw 2 photographs of different scenes. One photograph was a control scene in which familiar objects appeared in their canonical...

In this paper, we consider the aesthetic criteria and constraints related to the layouts of UML sequence diagrams. We consider the applicability of the traditional graph drawing aesthetics in drawing sequence diagrams. Because of the special nature of sequence diagrams, many of these aesthetics are not applicable. Based on our view on how these diagrams are read or viewed, we propose some new a...

Abstract Introduction Physiomesh/Securestrap system entered market in 2013 and despite its producer assurence it become a spectacular disaster, eliminating Ethicon from resulting multi-milion dollar lawsuits. The biological reasons for faileure of the Physiomesh implant were partly explained animal models. However conlusions suggested that apart components failure was mainly due to biomechanica...

BACKGROUND In preclinical studies, the combination of chronic stress and a high sugar/fat diet is a more potent driver of visceral adiposity than diet alone, a process mediated by peripheral neuropeptide Y (NPY). METHODS In a human model of chronic stress, we investigated whether the synergistic combination of highly palatable foods (HPF; high sugar/fat) and stress was associated with elevate...

Purpose: Eventration is a rare complication after laparotomy and its treatment is actually not standardized. We retrospectively analyzed 12 patients with early postoperative eventration; 8 of 12 were treated with use of biological mesh (non-cross-linked porcine derma). Materials and Methods: We observed, from January 2009 to January 2014, 12 patients with eventration. In 4/12 patients we perfor...

To date, the reverse abdominoplasty has been reported infrequently as a procedure to improve the upper abdominal wall contour. In this report, we report on our experience with the reverse abdominoplasty and on a review of the English-language literature by using PubMed to draw conclusions regarding optimal indication for this procedure, results, and complications. Over a 3-year period, we have ...
