A dual Padding Method for ischial pressure sore reconstruction with an inferior gluteal artery perforator fasciocutaneous flap and a split inferior gluteus maximus muscle flap.
Archives of plastic surgery, 2019Co-Authors: Gordon K. Lee, Saehoon Yoon, Eui Cheol JeongAbstract:BACKGROUND Various surgical management Methods have been proposed for ischial sore reconstruction, yet it has the highest recurrence rate of all pressure ulcer types. A novel approach combining the advantages of a perforator-based fasciocutaneous flap and a muscle flap is expected to resolve the disadvantages of previously introduced surgical Methods. MethodS Fifteen patients with ischial pressure ulcers with chronic osteomyelitis or bursitis, who underwent reconstructive procedures with an inferior gluteal artery perforator (IGAP) fasciocutaneous flap and a split inferior gluteus maximus muscle flap from January 2011 to June 2016, were analyzed retrospectively. The split muscle flap was rotated to obliterate the deep ischial defect, managing the osteomyelitis or bursitis, and the IGAP fasciocutaneous flap was rotated or advanced to cover the superficial layer. The patients' age, sex, presence of bursitis or osteomyelitis, surgical details, complications, follow-up period, and ischial sore recurrence were reviewed. RESULTS All ischial pressure ulcers were successfully reconstructed without any flap loss. The mean duration of follow-up was 12.9 months (range, 3-35 months). Of 15 patients, one had a recurrent ulcer 10 months postoperatively, which was repaired by re-advancing the previously elevated fasciocutaneous flap. CONCLUSIONS The dual-flap procedure with an IGAP fasciocutaneous flap and split inferior gluteus maximus muscle flap for ischial pressure ulcer reconstruction is a useful Method that combines the useful characteristics of perforator and muscle flaps, providing thick dual Padding with sufficient vascularization while minimizing donor morbidity and vascular pedicle injury.

Conductive cotton fabric through thermal reduction of graphene oxide enhanced by commercial antioxidants used in the plastics industry
Cellulose, 2019Co-Authors: Maciej Jedrzejczyk, M. Svyntkivska, Tomasz Makowski, Urszula Mizerska, Witold Fortuniak, Stefan Brzeziński, Ewa Piorkowska, D. KowalczykAbstract:Electrical conductivity was imparted to a cotton fabric through thermal reduction of graphene oxide. The reduction was enhanced by commercial antioxidants used in the plastics industry. The cotton fabric was coated with GO by the Padding Method and dipped in antioxidant solution. After drying, the antioxidant assisted reduction of GO was conducted at 220 °C in air. The electrical properties and hydrophobicity of thus-modified fabric were examined. The structure of materials was analyzed by atomic force microscopy and scanning electron microscopy. Application of the antioxidants permitted to reach lower values of surface electrical resistivity of the fabric. After the reduction all fabric samples became hydrophobic.Graphical abstract

Superhydrophobic properties of cotton woven fabrics with conducting 3D networks of multiwall carbon nanotubes, MWCNTs
Cellulose, 2014Co-Authors: T. Makowski, D. Kowalczyk, Witold Fortuniak, S. Brzezinski, D. Jeziorska, A. TraczAbstract:This article presents the findings concerning the preparation and properties of cotton woven fabrics with a conductive network made of multiwall carbon nanotubes deposited on the fiber surface by the Padding Method. The next stage of treatment consisted of imparting superhydrophobic properties to the fabrics in solution with methyltrichlorosilane (MTCS) in a waterless medium. The tests performed show that the state of surface and water content in cotton fibers exerts a significant influence on the hydrophobic properties of the analyzed samples. In order to explain the differences in hydrophobic properties, the morphology of the cotton fabric surface was examined using samples with various water contents. The formation mechanism of MTCS coatings on cotton fabric has been proposed.

video based compression for plenoptic point clouds
Data Compression Conference, 2020Co-Authors: Shan LiuAbstract:In this paper, we first extend the video-based point cloud compression (V-PCC) to support the plenoptic point cloud compression by generating multiple attribute videos. Then based on the observation that these videos from multiple views have very high correlations, we propose encoding them using multiview high efficiency video coding. We further propose a block-based Padding Method that unifies the unoccupied attribute pixels from different views to reduce their bit cost.

A Dedicated Greedy Short Path Padding Solution Method for Error Resilient Circuit Designs
IEEE Access, 2020Co-Authors: Zhijian Chen, Xiaoyan Xiang, Taotao ZhuAbstract:Resilient circuits represent promising approaches for improving both circuit performance and tolerance for dynamic variations. However, the short path Padding problem becomes severe during the implementation, resulting in significant area overhead and even frequency degradation, which might nullify the benefits of resilience. The present work addresses this issue by proposing a progressive resilient design Methodology, including a clock period prediction Method that can accurately access the minimum clock period possible in an early stage and a short path Padding Method, based on the greedy heuristic algorithm to reduce both the total Padding delay and the runtime. The runtime for the Padding stage is further minimized by introducing an accelerated Padding Method that decreases the number of point visits required during the greedy Padding process. The proposed Methodology is applied to several benchmark circuits, decreasing averagely 26.1% in the total number of Padding buffers and 38.1% in the runtime, compared to a present state of the art Methodology. Thus, this proposal not only avoids iterations of Padding assignments by early period prediction, but also is a feasible and effective short path Padding Methodology for resilient circuits.
