The growth of the Web in recent years has resulted development various online platforms that provide healthcare information services. These contain an enormous amount information, which could be beneficial for a large number people. However, navigating through such knowledgebases to answer specific queries consumers is challenging task. A majority might non-factoid nature, and hence, traditional keyword-based retrieval models do not work well cases. Furthermore, many scenarios, it desirable...

Answering questions in many real-world applications often requires complex and precise information excerpted from texts spanned across a long document. However, currently no such annotated dataset is publicly available, which hinders the development of neural question-answering (QA) systems. To this end, we present MASH-QA, Multiple Answer Spans Healthcare Question consumer health domain, where answers may need to be multiple, non-consecutive parts text We also propose MultiCo, architecture...

Program translation aims to translate source code from one programming language another. It is particularly useful in applications such as multiple-platform adaptation and legacy migration. Traditional rule-based program methods usually rely on meticulous manual rule-crafting, which costly both terms of time effort. Recently, neural network based have been developed address this problem. However, the absence high-quality parallel data main bottlenecks impedes development models. In paper, we...

There has been a recent surge of interest in automating software engineering tasks using deep learning. This article addresses the problem code generation, which goal is to generate target given source different language or natural description. Most state-of-the-art learning models for generation use training strategies primarily designed language. However, understanding and generating requires more rigorous comprehension syntax semantics. With this motivation, we develop an encoder-decoder...

Augmented reality (AR) technology can superimpose the virtual image generated by computer onto real operating field to present an integral enhance surgical safety. The purpose of our study is develop a novel AR-based navigation system for craniofacial surgery. We focus on orbital hypertelorism correction, because surgery requires high preciseness and considered tough even senior surgeon.Twelve patients with were selected. preoperative computed tomography data imported into 3-dimensional...

Entity linking is the task of mentions named entities in natural language text, to a curated knowledge-base. This significant importance biomedical domain, where it could be used semantically annotate large volume clinical records and literature, standardized concepts described an ontology such as Unified Medical Language System (UMLS). We observe that with precise type information, entity disambiguation becomes straightforward task. However, fine-grained information usually not available...

Background: An augmented reality tool allows for visual tracking of real anatomic structures in superposition with volume-rendered computed tomographic or magnetic resonance imaging scans and thus can be used navigated translocation important during operation. In this feasibility study, ARToolKit was mandibular angle oblique split osteotomy to define the cutting planes according an operative plan. Methods: We overlay plan on model a mandible made by rapid prototyping technology, technology...

A novel multifocus color image fusion algorithm based on the quaternion wavelet transform (QWT) is proposed in this paper, aiming at solving blur problem. The method uses a multiresolution analysis procedure transform. performance of scheme assessed by some experiments, and experimental results show that effective performs better than existing methods.

Abstract Genioplasty is the main way to treat diseases such as chin asymmetry, dysplasia and overdevelopment, which involve three-dimensional direction abnormalities of chin. Since this kind surgery mainly uses intraoral incisions, narrow surgical field incisions surrounding important neurovascular tissues make it easy for complications, occur during osteotomy process, results in greater risks. The first craniofacial-plastic robot (CPSR-I) system developed complete precise positioning...

In perforator flap transplantation, dissection of the is an important but difficult procedure because high variability in vascular anatomy. Preoperative imaging techniques could provide substantial information about anatomy; however, it cannot direct guidance for surgeons during operation. this study, a navigation system (NS) was established to overlie map on surgical sites further guide transplantation.The NS based computed tomographic angiography and augmented reality techniques. A virtual...

Abstract The authors have developed a novel augmented reality (AR)-based navigation system (NS) for craniofacial surgery. In this study, the aimed to measure precision of and further analyze primary influencing factors precision. drilling holes into mandibles ten beagle dogs was performed under AR-based NS, analyzed by comparing deviation between preoperational plan surgical outcome. NS successfully applied quickly precisely drill in mandibles. mean positional preoperative design...

IEEE 802.11 standard leaves client to determine AP association selection and initiate handoff. This often leads sub-optimal results in enterprise WLAN with a large number of users. Therefore, network operators expects the ability dominate handoff initiation so that better AP/client can be achieved. In addition, procedure involves time-consuming packets exchange. Although many methods have been proposed simplify procedures, there is at least hundreds milliseconds during which client's data...

Background: As three-dimensional technology becomes more ubiquitous, many plastic surgical applications have emerged. The authors investigate a scanning and printing system for facial soft tissue reconstruction in conjunction with an anterolateral thigh dermal adipofascial flap the treatment of Parry-Romberg syndrome. Methods: Seven patients atrophy zygomatic, buccal, mandibular areas were included. Three-dimensional each patient's face was analyzed computer-aided design (CAD) to quantify...

Double eyelidplasty has 3 key factors: motor power, connecting tissue, and skin adhesion.To create natural double eyelid, new anatomy structure should be rebuilt according to physiological eyelid in these aspects.Levator aponeurosis is used as "connecting tissue" transmit dynamic "motor power" of levator muscle upper "skin adhesion" induced between a plane manner. Postoperation evaluation includes stability asymmetry, fold curve, scar formation.A total 119 patients were operated on this...

Today's enterprise WLAN is facing challenges as the rapid growth of user scale and traffic load. Users often experience slow or even intermittent connection in crowded area. This mainly due to interference among densely-deployed access points (APs). In this paper, we took advantages emerging idea SDN OpenFlow technology mitigate WLAN. Specifically, proposed an OpenFlow-based framework for framework, a central controller takes control over all APs via interface. By installing appropriate...

The repair of fronto-orbital nasal bone defects may be a troublesome problem to plastic surgeons. This report aims present the results reconstruction with prefabrication epoxied maleic acrylate/hydroxyapatite compound (EH compound) using 3-dimensional (3D) imaging data and computer-assisted manufacturing techniques, sometimes combined autogenous defect. Helical computed tomography were used create 3D model patient's skull. On basis these data, individual shape implant was created by...

To suit the needs of data collection, routing protocols in WSN are normally required to form a collection tree where flows from source nodes sink nodes. These protocols, such as CTP and Multihop LQI, generally target at reducing packet delivery cost without considering load balancing issues. We argue that is crucial for WSNs because imbalance may cause certain nodes, which we call hot spots, run out energy faster than expected. The lead holes prominently degrade performance network. In this...
