Structural variation is important in disease etiology and ecological adaptation. Prior work has focused on using either only short paired-end reads or a hybrid approach that combines long and short reads to detect structural variants. Few methods have focused solely on using long reads. Here, we aim to detect a specific type of structural variation, large inversions, using only raw PacBio long reads...
A multimodal optical imaging system combining all optical photoacoustic tomography and optical coherence tomography angiography is developed for human skin imaging. Various different types of skin disorders can be imaged by this system.
Vection is an illusion sensation of self-motion provoked by watching visual oscillation. Traditionally, vection perception has been qualified using frequency responses. Indeed, the concept of frequency response is a common way to quantify the responses of visual oculomotor functions such as optokinetic nystagmus (OKN) and vestibular ocular reflex (VOR). This study explores whether frequency is the...
Exploitation and using of clean and renewable energy to improve the domestic energy structure is important for building smart city. Photovoltaic (PV) power generation is a good choose, and modules inspection is an important direction of PV power generation. The manual inspection is a common way but is not feasible for large-scale PV systems in practice due to low efficiency, high error rate and long...
ITER is a large scale fusion experimental device under construction in Cadarache (France) intended to prove the viability of fusion as an energy source. Ion Cyclotron Resonance Heating (ICRH) system is one of the three heating systems which will supply total heating power of 20 MW (40-55 MHz) up to one hour of operation. Radio-Frequency (RF) contacts are integrated within the antennas for assembly...
We describe a scanning thermal microscope that uses a fluorescent nanocrystal as a temperature probe. The nanocrystal is made of an inorganic fluoride material doped with erbium ions. The temperature is determined by measuring the fluorescence intensity ratio between two adjacent fluorescence lines. We first visualized the heating of a Cr stripe, and observed two different heat transfer channels,...
A new system is proposed to reduce the transmission delay of visual and non-visual medical records by using edge caching and Dynamic Vision Sensing (DVS) technologies. The results of simulation show that the proposed scheme can decrease the transmission delay by 36.35% to 86.88% compared to a system with edge caching only.
Resolving and identifying the structure and composition of atoms in a solid material at atomic resolution has been a long-standing goal of analytical microscopy. Controlling crystalline interfaces at the atomic scale is now actively being research in the broader range of materials science and device engineering fields. However, the atomic resolution of electron optics instrument was limited by the...
Can venture capital (VC) firms transform a weak innovation ecosystem into a productive and robust one? While the literature has found VC firms' catalyst role in innovation in developed markets, we know little about whether and how they affect innovation in an emerging market, where formal legal- and market institutions and networks of professional intermediaries for them to play a catalyst role are...
With the increasing size of the wind farms, the impact of the wake effect on the energy yields and lifetime consumption of wind turbine can no longer be neglected. In this paper, the affecting factors like the wind speed and wind direction are investigated in terms of the single wake and multiple wakes. As the power converter is the most fragile component among the turbine system, its lifetime estimation...
FDSOI is one of the alternative device architectures chosen to extend CMOS scaling for high-k metal gate. FDSOI is ideal for applications needing a balanced trade-off among power, performance and cost, such as the Internet of Things (IoTs). One of the challenges in FDSOI integration is to obtain a low gate to source drain capacitance (overlap capacitance or DC capacitance). To enable this, low k spacer...
In this work, we report the development and realization of ultrahigh-frequency, high-performance nano interdigital transducers (n-IDTs) for generation of surface acoustic wave (SAW) on aluminum nitride (AlN)/diamond/Si substrates, where the metal fingers are embedded in the AlN film. The well-defined n-IDTs' resolution down to 200 nm were obtained using electron beam lithography, inductively coupled...
The three stage experiments including without assistance, uniaxial ultrasonically assisted and biaxial ultrasonically assisted machining systems on quartz glass milling were constructed in this study in order to verify the assisted effect on cutting performance and to compare the merit and limitations among them. First of all, the milling experiment without assistance was performed to investigate...
The intermittency in wind power can face electrical network with some challenges such as power quality, frequency deviation and reliability of the system. So estimated power fluctuation in wind farm has to be known in order to reach to the grid integration requirements. In this paper the wind farm power fluctuation is investigated by considering the three factors; wake effect, turbulence and spatial...
DC bias flux density exists in many types of electrical machines such as permanent-magnet synchronous machines (PMSM), brushless DC machines (BLDC) and switched reluctance motors (SRM), etc.
Two dimensional (2-D) inter-symbol-interference (ISI), consisting of ISI in the down track direction and inter-track interference (ITI) along the cross-track direction, is a major factor that severely degrades the performance of ultra-high density magnetic recording systems.
dv/dt Immunization is one of the main issues for MOSFETs cascode with GaN HEMT. This paper presents a method to numerate dv/dt immunization limit of LV MOSFET. This method applies to LV MOSFET in cascode GaN FET and MOSFET in switching-mode application. Dv/dt immunization limit of recent LV MOSFET is presented in this paper.
Convolution is a fundamental operation in many applications, such as computer vision, natural language processing, image processing, etc. Recent successes of convolutional neural networks in various deep learning applications put even higher demand on fast convolution. The high computation throughput and memory bandwidth of graphics processing units (GPUs) make GPUs a natural choice for accelerating...
Broad area lasers having narrower rear-facet width compared to front-facet have been fabricated to achieve suppression of higher order mode in the lateral direction. Consequently, slow-axis divergence has been reduced by over two times at current density >3kA/cm2 making possible fiber-coupled power >200 W from 105µm and 0.15NA beam.
