We demonstrate a stable ultrafast all-fiber laser based on filter-driven four wave mixing using a microfiber resonator which serves both as filter and a high nonlinear element.
Reflection, which is widely used in practice and abused by many security exploits, poses a significant obstacle to program analysis. Reflective calls can be analyzed statically or dynamically. Static analysis is more sound but also more imprecise (by introducing many false reflective targets and thus affecting its scalability). Dynamic analysis can be precise but often miss many true reflective targets...
With the extensive application of machine learning algorithms in bioinformatics, more and more computer researchers are beginning to focus on this field. Polyadenylation of messenger RNA (mRNA) is one of the key steps of gene expression in eukaryotes, polyadenylation site marks the end of transcription, it is of great significance to explore prediction of the site of gene sequences encoding gene....
Transmission lines are used to deliver power flow of electromagnetic wave with little dissipating loss due to non-radiated symmetrical structures. With the motivation of new design recipe of series-fed antenna arrays, transmission lines are engineered for radiation by breaking the field symmetry. Here, in this paper, we have summarized several strategies to break the field symmetry of typical transmission...
The Locator/Identifier Separation Protocol (LISP) separates classical IP addresses into two categories: one for identifying terminals, the other for routing. To associate identifiers and locators LISP needs a specific mechanism, called mapping system. This technology is still at an early stage but two experimental platforms have already been deployed in the Internet: LISP Beta Network and LISP-Lab...
For the miniaturization and multifunction of electronic devices, the vertical interconnection technology has been developed to replace the traditional planar packaging technology. The interposer connection using double-side solder bump is used as the vertical interconnection technology in this study. Three kinds of solder bumps with different diameters of 0.76mm, 1.2 mm and 2mm were prepared and mounted...
Conventional decision feedback equalizers (DFEs) suffer from the fundamental drawback of shrinking rather than increasing data eyes when consecutive 1s or 0s are present in data. To combat this drawback, a new data-transition adaptive DFE is proposed. The proposed DFE takes into account the dependence of post-cursors on the polarity of data and searches for optimal tap coefficients using a sign-sign...
Data-state decision feedback equalizers (DFEs) suffer from a fundamental drawback of deteriorating vertical eye-opening when consecutive 1s or 0s are present in data. To combat this, a new data-transition adaptive DFE termed data-transition DFE is proposed. We show that data-transition DFE does not reduce vertical eye-opening whereas data-state DFE shrinks vertical eye-opening when consecutive 1s...
Bonding front propagation driven by the work of adhesion is restricted by the air drag and mechanical deformation of wafers. Energy variation during room temperature bonding can influence the bonding initiation and front propagation dramatically. In order to evaluate the dissipated energy and elastic strain energy resulting from the air cushion and the wafer bow, both theoretical and finite element...
Different from electric current, the magnetic current can't be supported on a piece of metallic wire or similar structures. It is usually designed as an equivalent concept using electric small loops. In this paper, we have proposed a method to synthesize the magnetic current in a simple but not trivial structure, compared with the existing ways. A cavity is utilized to provide an aperture to perform...
The postMessage feature in HTML5 allows web components of different origins to communicate with each other. However, the message receivers do not differentiate the origins of a message, making information leakage possible. Being aware of this vulnerability, We examine its implication under the context of Single Sign On (SSO) mechanism. Nowadays, many websites integrate SSO to facilitate easier user...
A multiwavelength Er-doped fibre ring laser system using all fibre Lyot filter and highly nonlinear fibre was experimentally demonstrated, with degree of polarization up to 99.9% and 50 channels output.
The diagnosis of benign and malignant thyroid nodules timely and correctly is always a core problem for the clinical practice of thyroid nodules. Traditionally, preoperative diagnosis process of benign and malignant thyroid includes two stages: ultrasound check and fine needle aspiration. The malignant thyroid nodules will be further confirmed by surgery and pathology. However, such traditional diagnosis...
This work focuses on how to provide the best virtual desktop technology, virtualization performance and hardware in the computer classroom. There are using the three popular virtualization technologies in the same environment to establish the same conditions, pure performance comparison: VMware Horizon, Citrix XenDesktop, and Microsoft VDI. Test software used to the current popular software, system...
Data open sharing becomes the basis for mining the potential value of big data. Due to the different structure of different shared data sources, the upper layer application is restricted. Therefore, how to establish a unified and user friendly logical organization form is an urgent problem to be solved in the open sharing of data. This paper presents a method of data organization based on ontology...
Computer aided analysis for Failure Modes and Effects Analysis (FMEA) is an important development direction. Failure analysis (failure mode and failure mechanism analysis) is the most critical and the most difficult step in implementation of FMEA. The procedure of failure analysis is lack of formal and standardized method, which hindering the computer integrated process. In face of complex products,...
In this paper, a patch-fed slot antenna with air cavity is proposed in millimeter-wave band. The antenna is manufactured by using the silicon micromachining technology which is utilized to designed air cavity structure and mitigate dielectric loss in the millimeter-wave band. However, this technique is based on silicon processing, the large permittivity difference between the air (εr = 1) and silicon...
Dental pulp stem cells (DPSCs) are stem cellspresent in the dental pulp and have same renewal anddifferentiating properties as bone marrow cells. Hence, DPSCs canbe used for future regenerative therapies of various diseases.Previous studies show that DPSCs would lose their differentiationcapability during long-term passage when they were cultured inmedium promoting differentiation. Researchers have...
Bio-inspired electronic arrays (BIEAs) are circuits that consist of electronic cells. Their self-repairing ability results in high reliability, which brings them many potential demands in aviation field. Recent developments on self-organization and self-repairing methods of BIEA have led to a demand for fault detection as it is the premise of self-repairing. However, the conventional fault detection...
When faults happen at gas path components of gas turbines, some charged abnormal debris will be generated. An electrostatic sensor can be installed at the tail end of the exhaust pipe to monitor the abnormal debris online and further indicate the faults. However, the electrostatic sensor itself is faced with a problem of function failure because of a severe working condition of high temperature and...
