In this paper, we present a novel depression dis-order classification algorithm, named weighted discriminative dictionary learning (WDDL), based on functional magnetic resonance imaging (fMRI) data. The underlying relationship between samples and dictionary atoms is exploited by introducing an adaptive weighting scheme. Tested on fMRI data of 29 patients with depression and 29 healthy controls, our...
We consider long-haul sensor networks where sensors are remotely deployed over a large geographical area to perform certain tasks, such as tracking and/or monitoring of one or more dynamic targets. A remote fusion center fuses the information provided by these sensors to improve the accuracy of the final estimates of certain target characteristics. In this work, we pursue artificial neural network...
This paper reports a new scalable behavioral modeling technique for silicon controlled rectifier (SCR) based electrostatic discharge (ESD) protection structures using Verilog-A language. Accurate models were developed for various low-triggering voltage SCR ESD (LVSCR) protection structures implemented in a foundry 180nm RF process, which were validated by circuit simulation and ESD measurement.
This paper reports a new scalable behavioral modeling technique for novel nano crossbar ESD protection structures using Verilog-A language. Accurate models for nano crossbar ESD protection structures with different sizes were developed, which were validated by circuit level simulation and transmission line pulsing ESD measurement.
This paper reviews recent advances in 3D on-chip electrostatic discharge (ESD) protection design for integrated circuits (IC). Traditional ESD protection relies on PN-junction-based structures, which have inherent disadvantages including fixed ESD triggering and parasitic effects. New ESD protection mechanisms and structures, including nano crystal dots and nano crossbar concepts, provide alternative...
Based on practice, this essay presents a concise and practical method on development of small and medium software. Combining process management and document management, the author rationally uses QA(Quality Assurance), CVS(Concurrent Versions System), Checksheet and other management mechanisms to include the compilation of different documents and codes into an unified process. The author shows the...
This paper reports a tunable low triggering voltage, dual-directional SCR ESD protection structure in CMOS for RF ICs. A new embedded gate-coupling technique is used to reduce and adjust its triggering voltage. Experiment shows a low discharging resistance of ~0.26Ω, low leakage current of ~0.19nA, low parasitic capacitance of ~150fF and ultra fast response time of ~100pS. This structure achieves...
Electrostatic discharge (ESD) protection becomes essential to advanced integrated circuits (IC). Very fast IEC-ESD failure and protection design are emerging challenges for contemporary ICs, particularly for consumer and portable electronics. This paper presents a new mixed-mode IEC-ESD simulation-design method, which involves process, device, circuit and system level simulation to accurately address...
In this paper, CDA&A, a program for develop the professional acquisition and analysis software for engineering measurement written with Lab Windows/CVI. CDA&A includes many features of general interest to generate the professional measurement software (PMS), such as data acquisition, data display, data processing, and file operations. As the program is written using Lab Windows/CVI, a C-programming...
The structure, working principle and fabrication of a humidity sensor based on carbon nanotubes (CNTs) were presented. The sensor resistance was sensitive to humidity. Schrödinger equation associated to the potential barrier between two CNTs was set up and solved. The analysis results indicated that the fluctuation of sensor resistance was caused by instability of CNTs, and the testing frequencies...
This paper reports design of a novel low-parasitic ultra-low-triggering voltage dual-directional LTdSCR ESD protection structure in foundry CMOS.

This article proposes that when aviation product receives laboratory reliability verification test, the selection of statistical plans is undertaken according to the product features. With considering the effect of selecting statistical plans according to aviation product features, analysis and related suggestion are given when performing reliability verification test on the aviation product in lab.
The AC breakdown voltages of a fluorocarbon were measured under three states, including in gaseous state, in boiling two phase flow state and in liquid state. Because the insulating medium in two phase flow could be used in some electrical apparatus, the author measured the breakdown voltage of two phase flow under various pressures in the vessel, various water contents in the coolant. The results...
