A fiber-optic capillary (FOCap) gas chromatography detector was employed to measure eluting volatile organic compounds (VOCs) through the localized surface plasmon resonance (LSPR) of thiolate monolayer-protected nanoparticles. The 1-octanethiol silver nanoparticles (C8-AgNP) were synthesized through reduction with sodium borohydride. The inner wall surface of the FOCap detector is modified with (3-mercaptopropyl)...
Nowadays, more and more methods have been proposed to solve the problem of face detection based on computer implementation. Due to the variations in background, illumination, pose and facial expressions, the problem of machine face detection is complex. Recently, deep learning approaches achieve an impressive performance on face detection. In this paper, a model named Multi-Scale Fusion Convolutional...
In this paper, we study single pursuer and single evader pursuit-evasion game with different sensing radius and unequal maximum moving speeds. Both players are restricted in a closed area. The pursuer is assumed to move according to a greedy strategy. We propose an escape strategy for the evader to avoid being driven to the corner and to escape. We obtain that when the pursuer moves faster, the evader...
This paper is aimed at the uncertain dynamics and kinematics of the master-slave manipulators for nonlinear bilateral teleoperation system in the presence of constant time delays and external disturbances in the task space. On the basis of neural networks adaptive control methods, we propose an integral-type neural networks adaptive sliding-mode controller to solve the problem of dynamic uncertainties...
Random dopant fluctuation (RDF) is one of fluctuation sources in sub-7-nm semiconductor technology node. In this paper, we estimate the timing and power fluctuations on 10- nm-gate gate-all-around (GAA) silicon nanowire (NW) complementary metal-oxide-semiconductor (CMOS) circuit induced by various random discrete dopants (RDDs) from channel (with/without doping), source/drain (S/D) extensions and...
Magnetic is a promising technical for positioning in the GNSS denied scenarios such as parking lot and tunnel, since the magnetic field exists everywhere on the earth. In this paper, for vehicle navigation, an odometry assisted magnetic matching algorithm is proposed, in which the magnetometer and the odometry of vehicle are used. The proposed scheme consists of two phases: offline phase and online...
This paper presents a wirelessly-powered and free-floating implantable optogenetic stimulating (FF-WIOS) implant with negligible footprint and high power transfer efficiency (PTE). FF-WIOS ASIC with embedded μLED and reflective lens is expected to stimulate the target cortical neuronal ensembles at high temporal and spatial resolution with minimal damage and no tethering effects. To improve the PTE,...
Epilepsy is a typical neurological disorder. To find the characteristics of epilepsy, scalp level connectivity is one of the interests that widely studied before. However, another aspect about the scalp representative channels, which presents the synchronous regions, has not yet been investigated. In this work, we focus on study the scalp responses of epilepsy by connectivity and representative channels...
We perform experimentally validated statistical device simulation to explore characteristic fluctuation induced by random discrete dopants (RDDs) inside the source / drain extensions of undoped gate-all-around silicon nanowire MOSFETs. The engineering findings of this study indicate that both the DC and dynamic characteristic fluctuation caused by RDDs of the drain extension has relatively smaller...
The application of the spaceborne stripmap range sweep synthetic aperture radar (SS-RSSAR) is limited by its fixed azimuth beam pointing. In this paper a more advanced spaceborne azimuth-range sweep synthetic aperture radar (ARSSAR) is proposed to illuminate the region of interest (ROI) by simultaneously sweeping the beam in range and in azimuth. In this case, more balances of the azimuth resolution...
Identifying cis-regulatory modules (CRMs) is one of the important challenges in molecular biology, and the current computing methods are still the main way to find CRMs. However, these methods generally have a problem of high false positive rate, and one of the ways to reduce the false positive rate is the parameter optimization. Overcoming the deficiency of traditional CRMs identification methods,...
In this paper, we present the design, fabrication and the function of a soft actuator embedded with Low-Melting-Point Alloy (LMPA). By melting the metal via joule heating, the phase of the metal transformed from the solid state to the liquid state, by which the stiffness of the actuator changed over nearly an order of magnitude. Through a reheating-recrystallizing circle, the actuator can self-healing...
Reinforcement learning through an agent to learn policy use trial and error method to achieve the goal, but when we want to apply it in a real environment, how to dividing state space becomes difficult to decide, another problem in reinforcement learning, agent takes an action in the learning process according to the policy, we will encounter how to balance exploitation and exploration, to explore...
We have successfully exploited multi-dimensional spaces of concentrations of the interstitial species, Si and Ge, geometries and compositions of the starting SiGe nano-pillar, and sources of Si interstitials (the Si3N4 and Si encapsulation layers) to create new classes of exciting optical and electronic devices such as single-electron tunneling devices, wavelength-tunable photodetectors, and MOSFETs.
In this work we study the random telegraph noise (RTN) characteristics of short-channel gate-all-around (GAA) poly-Si junctionless (JL) nanowire (NW) transistors. The test devices were fabricated with I-line-based lithography in combination with novel spacer-etching techniques for aggressively shrinking the channel dimension. Based on the tiny nanowire channel and short-channel length, we are able...
We report a monolithic wafer-level fabrication method for a hemispherical reflector coupled light-emitting-diode (LED) array using isotropic etching of silicon. These neural stimulators collect the backside as well as the front side emission of the μ-LEDs and thus provide higher intensity, which is imperative for opsin expressions in optogenetics experiments. Aluminum was used as the reflective layer...
As a large number of electrical and electronic equipment is introduced into the car, the reliability and safety of MCU becomes increasingly important. When the vehicle safety failure occurs, it must enter a safe driving state to ensure that the vehicle is traveling in the safest mode, so it is necessary to analyze the functional safety of MCU. Based on the road safety standard ISO 26262 and the running...
We experimentally demonstrated that the inclusion of Ge dots into the gate stack of a Si MOSFET provides extremely high photoresponsivity over 1,000A/W and superior photoresponse linearity of at least 7 decades for 400–1300nm illumination, depending on whether the Ge-dot photoMOSFET operates in the inversion or accumulation modes. Remarkably a very large photocurrent gain of 103–108A/A and a significantly...
Ge-dot/SiO2/SiGe-channel photoMOSFETs are demonstrated on Si substrate. A decrease in the dot size and gate oxide thickness significantly enhances the photoresponsivity (9000A/W) with 6nW under 850nm illumination, and improves response time (0.48ns) and power consumption.
With the advent of genetically-encoded optical tools to trigger or report neuronal activity, new designs for multielectrode arrays (MEAs) used in neural interfacing incorporate both optical and electrical modes of stimulating or recording neural activity. Likewise, the need to improve upon the biocompatibility of implanted MEAs has moved the field towards the use of softer, more compliant materials...
