We present channel multiplexing with a single optical intensity modulator by incorporating tandem optical single-sideband modulation and orthogonal multiplexing technique with DSP-assisted coherent detection. Quality factor above 6 is demonstrated experimentally for all BPSK channels.
In this paper, a biologically inspired 3D slithering gait for a snake-like robot is designed and implemented for the purpose of target tracking. First, by balancing the forward speed and the stability of the robot, a straight slithering gait is modelled, under which the robot can march straight, fast, and stably. Then, for the purpose of steering, the straight slithering gait is modified into a biased...
Based on cellular automata model, the impact of information suggestion on the traffic flow of a three-route system has been studied. In the model, we assume that a speed limit bottleneck exists on one route. When vehicles drive past this bottleneck, their speed will be reduced to 0. By simulation, it was found that a big traffic jam appears before this bottleneck. To alleviate this kind of traffic...
The solderability of component termination finishes degrades upon storage due to the combined effects of surface contamination, oxidation, corrosion and/or intermetallic compound (IMC) formation at the interface between substrate and finishes. Such solderability degradation impinges on the shelf-life of the electronics components and hence demands an in-depth understanding to ensure high reliability...
This paper reports characterization and analysis of diode string electrostatic discharging (ESD) protection structures fabricated in a foundry 28nm CMOS technology. Comprehensive measurements were conducted using very-fast transmission line pulse (VFTLP) tester for Charged Device Model (CDM) ESD protection. The analysis results reveal the I-V insights critical to practical ESD protection designs.
In this paper, a new routing strategy named as Distributed Multiple Path (DMP) routing strategy is proposed. To yield a high-efficiency transmission performance, the proposed DMP routing strategy utilizes the information of static network topology, as well as that of dynamic network transmission status. Specifically, for each of the routing Origin-Destination (O-D) node pairs, the DMP routing strategy...
The next few years promises drastic improvements to global navigation satellite systems. USA is modernizing GPS, Russia is GLONASS, Europe is moving ahead with its own Galileo System, and China is expanding its BeiDou system from a regional navigation system to a full constellation global navigation satellite system known as BeiDou-2/Compass. Chinese BeiDou satellite navigation system constellation...
The relentless technology scaling calls for reduced supply voltage for dynamic power suppression. On the other hand, transistor threshold voltage cannot be scaled at the same pace to avoid excessive leakage power. Consequently, the noise margin is significantly reduced, leading to the deployment of various noise management systems that handle runtime voltage emergencies. Most of these systems rely...
Based on the market demand and the competition pressure, using the value chain theory and multi level structural analysis model as the main direction of drug control, and analysis the dual reconstruction properties proceeding from numerical fitting of a resource and a variety of resources. Finally, on the basis of the analysis of the integrated management organization mode, the reconstruction is put...
Objective: The clinicopathologic features of central area and lateral neck lymph nodes metastasis were retrospectively analyzed in order to better understand the characteristics of cervical lymph node metastasis, and provide an objective reasonable choice basis of surgical treatment cervical lymph node for the surgeons. Methods: All patients from January 2008 to July 2010 in our hospital were collected,...
A 27-year-old man complained discontinuous nausea and vomit. He had a disease course spanning over 2 years, during which he had a sever weight loss (about 30kg). A diagnosis of gastric retention was made at the first visit. At the second time he was treated as anemia, hypoproteinemia and kidney stone. This time with resection of the goiter at the right chest, the patient was in remission of the symptoms...
Objective To determine the incidence and significance of delphian lymph node metastasis in papillary thyroid cancer(PTC) and evaluate the clinical significance of delphian lymphnode metastasis in PTC patients. Methods We reviewed themedical records of 182 patients with pathologically confirmedPTC who underwent thyroid surgery and were detected delphian lymph nodes between September 2013 and January...
Objective:To explore the effect of intraoperative parathyroid hormone (IOPTH) monitoring in parathyroid-ectomy for Primary hyperparathyroidism. Method:The clinical data of 41 PHPT patients who received IOPTH monitoring (IOPTH group) during surgery from January 2009 to December 2014 were retrospectively analyzed. The clinical manifestation, examination and changes of parathyroid hormone and Calcium...
Multiple combined with recurrence parathyroid carcinoma is rarely reported in literature. Compared with solitary parathyroid carcinoma, it is no doubt that multiple combined with recurrence parathyroid carcinoma would increase the difficulty of diagnosis, increase misdiagnosis and the risk of reoperation. A 64 years old male patient was diagnosed of parathyroid carcinoma in our department in july...
Objective: Discussing the ultrasonic and pathologic features of Diffuse Sclerosing Variant of Papillary Thyroid Carcinoma (DSVPTC) in order to raise awareness of this disease. Methods:To collect ultrasonic and pathologic features of 47 cases of DSVPTC which confirmed pathologically referred to Department of Thyroid Surgery, the First Hospital of Jilin University from 2008 to 2015. Results: Diffuse...
Objective: The Purpose of this article was to share experience in the treatment of postoperative chylous leakage in thyroid cancer radical resection and central lymph node dissection patients, and provide a reference for clinicians. Method: A retrospective analysis 5145 cases of patients information from October 2009 to October 2015 whom underwent thyroid radical resection and central lymph node dissection...
Background: The most serious complication of thyroidectomy and parathyroidectomy is recurrent laryngeal nerve (RLN) injury. Recurrent laryngeal nerve is known to have many anatomical variations. The non-recurrent inferior laryngeal nerve(NRLN) is an extremely rare asymptomatic but important anatomical variation, and it is very susceptible to damage during surgery. In this study, we investigated the...
The incidence of diffuse sclerosing variant of papillary thyroid cancer (DSVPTC) is relatively low, it is a uncommon type of papillary thyroid cancer. Current literature mostly focused on its ultrasound appearance, and the reports on its CT features of the disease are rare. Because of no significant tumor mass effect, this disease is easy to be misdiagnosed, so it is essential to improve the understanding...
Patients with severe salivary gland dysfunction is common due to Sjogrens syndrome or radiotherapy because of head and neck cancer. These patients often have dry mouth, taste loss, severe tooth decay, pain, inflammation of the oral mucosa. Nowadays, as the biological sciences development, a variety of new treatments continue to emerge. Wherein the gene therapy has become a research hotspot. This Technique...
Fast enumeration (FE) is a way of efficiency improvement in explicit enumeration. Since its development in 2013, FE gains much attention in the solution of integer programming problems. An integer programming problem is a mathematical optimization or feasibility programming in which some or all of the variables are restricted to be integers. In many cases, the problems can be divided into integer...
