Safe and easy hair transplantation utilizing KD spreader

Plastic and Aesthetic Research 2018年第2期5卷 1-7页

作者： Kuldeep Saxena Cosmazone Fue Hair Transplant Center Malad WestMumbai 400064India

Aim: An atraumatic insertion of graft is key to successful outcomes in this procedure but there is a definite learning curve in available techniques. Many physicians do not continue hair restoration practice because of the repeated initial failures. The goal of any technique or instrument in follicular unit extraction (FUE) is to extract an individual follicular unit without transaction and implanting it in recipient area without producing physical trauma to the follicular unit. This article describes a novel technique in which an innovative instrument, the KD spreader, that addresses all the problems faced by novice physicians during FUE hair transplantation. More importantly unique design of the instrument also solves the problem of fatigue of the operator's hands while performing the hair transplantation procedure. Methods: In this technique, the KD spreader, comprised of a shaft and a hook connected to the shaft are configured to allow the user to work efficiently. Two finger grip of the device provides efficient gripping for fatigue free operation. While performing FUE, the KD spreader provides sufficient traction at the time of scoring. During implantation of the grafts in premade coronal slits, this device provides adequate dilation and maximum visualization of the slit. Attachment of the graft holding plate reduces the chances of dehydration of the graft. Results: In this study, we have observed use of KD spreader definitely showed advantages over the conventional technique forceps. The KD spreader provides efficient gripping, maximum visualization of slit and better stretching force for the dilatation of the slit to adjust even bigger size follicular unit grafts. Conclusion: The KD spreader may improve ability of the beginners to perform FUE extraction and implantation smoothly.

The Anterior spreader Flap: A Minimally Invasive Alternative to the Auto spreader Flap in the Treatment of Patients with Nasal Valve Dysfunction

引用

International Journal of Otolaryngology and Head & Neck Surgery 2014年第4期3卷 184-189页

We present a new method of treatment for nasal valve dysfunction caused by insufficiency or stenosis in a patient who refused open septum revision despite a significant degree of septum deviation. The Anterior spreader Flap (ASF) technique was suggested as an alternative to open nasal septum revision and was performed under local anesthesia. Computational fluid dynamics (CFD) tests were performed pre- and post-operatively and our patient was asked to complete a self-assessment using a Visual Analog Scale (VAS) for nasal breathing (0 = free nasal breathing, 10 = complete nasal blockage) before and 12 months after surgery. The ASF is a minimally invasive endonasal procedure in which the caudal edge of the upper lateral cartilage is dissected from the septum, and folded inwards and fixed. The ASF allows for less airflow resistance and more free space. CFD techniques revealed a reduction in local pressure based on extended space. In addition, VAS scores improved from 9 to 2 points (right side) and from 8 to 2 points (left side). On the basis of these findings, the ASF technique can be considered a safe, minimally invasive spreader flap technique. It can easily be combined with other nasal surgical techniques, as it is necessary in most cases. In selected cases, the ASF may be performed as a single procedure in patients with nasal valve dysfunction caused by septum deviation as an alternative to open septum revision.

The Research on Adaptive Control Modeling of a Liquid Fertilizer spreader

引用

Engineering（科研） 2010年第2期2卷 113-117页

作者： Z.D. Yang 不详

This paper describes a general modeling and control approach for steering wheel variable rate liquid fertilizer applicator. An adaptive numerical modeling approach for describing the system input-output dynamics is proposed, and an optimal control that accounts for the control hardware limits is developed. Field tests have demonstrated the effectiveness of the theoretical development.

Event Detection and Identification of Influential spreaders in Social Media Data Streams

引用

Big Data Mining and Analytics 2018年第1期1卷 34-46页

作者： Leilei Shi Yan Wu Lu Liu Xiang Sun Liang Jiang School of Computer Science and Telecommunication Engineering Jiangsu University Department of Computing and Mathematics University of Derby

Microblogging, a popular social media service platform, has become a new information channel for users to receive and exchange the most up-to-date information on current events. Consequently, it is a crucial platform for detecting newly emerging events and for identifying influential spreaders who have the potential to actively disseminate knowledge about events through microblogs. However, traditional event detection models require human intervention to detect the number of topics to be explored, which significantly reduces the efficiency and accuracy of event detection. In addition, most existing methods focus only on event detection and are unable to identify either influential spreaders or key event-related posts, thus making it challenging to track momentous events in a timely manner. To address these problems, we propose a Hypertext-Induced Topic Search(HITS) based Topic-Decision method(TD-HITS), and a Latent Dirichlet Allocation(LDA) based Three-Step model(TS-LDA). TDHITS can automatically detect the number of topics as well as identify associated key posts in a large number of posts. TS-LDA can identify influential spreaders of hot event topics based on both post and user *** experimental results, using a Twitter dataset, demonstrate the effectiveness of our proposed methods for both detecting events and identifying influential spreaders.
