Knockdown of HSDL2 inhibits lung adenocarcinoma progression via down-regulating AKT2 expression
Authors: Shi Yujia , Mao Zhengdao , Huang Yanhua , Sun Yun , Cao Qi , Yin Xiaowei , Huang Jianan , Zhang Qian
Published: March 2020

The aims of the present study are to investigate the role of hydroxysteroid dehydrogenase-like 2 (HSDL2) in the progression of lung adenocarcinoma and illuminate the underlying molecular mechanisms. ShRNA targeting HSDL2 gene (siHSDL2) was utilized to knockdown (KD) HSDL2 expression. In vitro and in vivo experiments were carried out to investigate the effect of siHSDL2 on the progression of lung adenocarcinoma. Microarray hybridization and gene expression analysis were used to investigate effect of siHSDL2 on mRNA expression profile in lung cancer cell line H1299. Our data demonstrated that HSDL2 was up-regulated in lung adenocarcinoma tissue samples (P<0.001). Patients with high HSDL2 expression in cancer tissues had a worse overall survival (P<0.001). HSDL2 KD not only inhibited the proliferation, cell cycle, apoptosis, clone-formation, invasion and migration of lung adenocarcinoma cells in vitro (P<0.05), but also suppressed the growth and metastasis in vivo (P<0.05). HSDL2 KD resulted in up-regulation of 681 genes and down-regulation of 276 genes. HSDL2 KD down-regulated the protein expression and phosphorylation of protein kinase B β (AKT2) (P<0.001 and P<0.001, respectively) and protein expression of baculoviral IAP repeat-containing 3 (BIRC3; P=0.001), and up-regulated the phosphorylation of ERK (P<0.001). Rescue experiments showed that AKT2 overexpression reversed the suppression effect of siHSDL2 on cell proliferation (P<0.001), invasion (P<0.001) and migration (P<0.001) significantly. HSDL2 functions as an oncogene to promote the growth and metastasis of lung adenocarcinoma via promoting the expression of AKT2.
Language and Inhibition: Predictive Relationships in Children With Language Impairment Relative to Typically Developing Peers
Authors: Larson Caroline , Kaplan David , Kaushanskaya Margarita , Weismer Susan Ellis
Published: March 2020

Background

This study examined predictive relationships between two indices of language—receptive vocabulary and morphological comprehension—and inhibition in children with specific language impairment (SLI) and typically developing (TD) children.

Methods

Participants included 30 children with SLI and 41 TD age-matched peers (8–12 years). At two time points separated by 1 year, we assessed receptive vocabulary and morphological comprehension via standardized language measures and inhibition via a Flanker task. We used Bayesian model averaging and Bayesian regression analytical techniques.

Results

Findings indicated predictive relationships between language indices and inhibition reaction time (RT), but not between language indices and inhibition accuracy. For the SLI group, Year 1 inhibition RT predicted Year 2 morphological comprehension. For the TD group, Year 1 morphological comprehension predicted Year 2 inhibition RT.

Conclusions

This study provides preliminary evidence of a predictive relationship between language and inhibition, but this relationship differed between children with SLI and those with typical development. Findings suggest that inhibition RT played a larger predictive role in later morphological comprehension in children with SLI relative to the other relationships examined. Targeting inhibition skills as a part of language intervention may improve subsequent morphological comprehension.

Designing Occupational Therapy Home Programs for People With Aphasia: Aphasia-Friendly Modifications
Authors: Wallace Sarah E. , Donoso Brown Elena V. , Saylor Anna , Lapp Erica , Eskander Joanna
Published: March 2020

Purpose

The purpose of this article is to describe aphasia-friendly modification for occupational therapy assessments and home programs aimed at addressing upper extremity impairments for people post stroke.

Method

This article examines a case study example from a larger study (Wallace, Donoso Brown, Saylor, & Lapp,
2018
) that implemented aphasia-friendly material modifications into an occupational therapy home program. The participant was a 74-year-old man who survived a left hemisphere cerebrovascular attack 6 years prior to the study. The participant experienced upper extremity hemiparesis and aphasia post stroke and was appropriate for an occupational therapy home exercise program with aphasia-friendly modifications to facilitate comprehension of the home program. Aphasia-friendly modifications (e.g., gestures and visual aids) were made to assessments to support comprehension and participation. To support reading comprehension deficits during completion of the home program, the program materials had aphasia-friendly modifications, such as modified text, supportive images, and reduced cognitive load of exercises. Finally, research team members used supported conversational techniques during all study procedures.

Results

At the end of the home program, an interview with the participant revealed several outcomes regarding the home program and the aphasia-friendly modifications. The participant reported pictures and reduced text to be beneficial in understanding the instructions. He also indicated that he enjoyed completing the exercises independently (i.e., outside of a therapy office). The participant's motor function demonstrated changes in a positive direction, although not greater than the minimally detectable change for performance-based measures.

Conclusions

Aphasia-friendly modifications (e.g., modifying text, adding supportive images, and using gestures) were found to be supportive of participation in assessments for and creation of an upper extremity home program. Speech-language pathologists can support the participation of people with aphasia through interprofessional collaboration and consideration of environmental adaptations.

Authors: Xiang Mian , Yi Benshun , Tan Jianjun , Zhu Li , Zhou Anan
Published: March 2020

In this Letter, the authors investigate a modified encoding scheme of batched sparse (BATS) codes to improve the erasure floor performance. In the proposed regularised variable‐node (RBATS) codes, variable‐node degrees are regularised to maximise the minimum degree for transmission. The asymptotical decoding performance of RBATS codes is analysed by a tree‐based analysis. Furthermore, they optimise check‐node degree distribution of RBATS codes to decrease decoding overhead according to the decoding condition. It is demonstrated through simulation results that the optimised RBATS codes can not only lower the transmission overhead but also improve erasure floor performance compared with traditional BATS codes.
DeepVS: an efficient and generic approach for source code modelling usage
Authors: Hussain Yasir , Huang Zhiqiu , Zhou Yu , Wang Senzhang
Published: March 2020

The source code suggestions provided by current integrated development environment (IDEs) are mostly dependent on static type learning. These suggestions often end up proposing irrelevant suggestions for a peculiar context. Recently, deep learning‐based approaches have shown great potential in the modelling of source code for various software engineering tasks. However, these techniques lack adequate generalisation and resistance to acclimate the use of such models in a real‐world software development environment. This Letter presents DeepVS, an end‐to‐end deep neural code completion tool that learns from existing codebases by exploiting the bidirectional gated recurrent unit (BiGRU) neural net. The proposed tool is capable of providing source code suggestions instantly in an IDE by using pre‐trained BiGRU neural net. The evaluation of this work is two‐fold, quantitative and qualitative. Through extensive evaluation on ten real‐world open‐source software systems, the proposed method shows significant performance enhancement and its practicality. Moreover, the results also suggest that DeepVS tool is capable of suggesting zero‐day (unseen) code tokens by learning coding patterns from real‐world software systems.

Published: March 2020

Temperature and humidity are the main factors that cause the decomposition of Nomex paper widely used as turn‐to‐turn insulation material of mining dry‐type transformers. In this study, for understanding the effect of ambient humidity and thermal aging on the properties of Nomex paper, specimens with the initial moisture content of 7% were aged in the oven for 168, 504, 672 h at 180°C, respectively. After thermal aging, corona discharge experiments of unaged and aged specimens with different aging degrees were carried out at different relative humidity (RH) levels from 10 to 70%. The characteristic parameters of corona discharge, such as the average discharge amplitude and the number of discharges, were measured. Then, the surface conductivity and the surface potential decay rate were measured. The morphology and attenuated total internal reflectance Fourier transform infrared spectroscopy were also analysed for explaining the difference of properties between unaged and aged specimens. The experiment results indicate that the average discharge amplitude decreases with the increase of RH or the deepening of the aging degree of specimens, but the number of discharges shows the reversal tendency. The changes in the physical structure and chemical composition, which is induced by the hydrolysis reaction of Nomex paper, accelerate the surface potential decay and increase the surface conductivity.

Authors: Gao Yunlong , Yang Chengyu , Lin Kuo‐Yi , Pan Jinyan , Li Li
Published: March 2020

Fuzzy c‐means algorithms have been widely utilised in several areas such as image segmentation, pattern recognition and data mining. However, the related studies showed the limitations in facing imbalanced datasets. The maximum fuzzy boundary tends to be located on the largest cluster which is not desirable. The overall fuzzy partition results in false grouping of edge objects and weakens the compactness of cluster. It is important the clusters are delineated by the maximum fuzzy boundary. In this study, a semi‐fuzzy c‐means algorithm is proposed by combining hard partition and soft partition. This study aims to provide an effective partition for the edge objects, such that the compactness of cluster can be improved. The proposed algorithm integrates the semi‐fuzzy c‐means method with the size‐insensitive integrity‐based fuzzy c‐means algorithm. In particular, the latter algorithm has the ability to deal with imbalanced data. With the experiment validation, the proposed algorithm is robust and outperforms the two component algorithms by using synthetic and widely known benchmark datasets.

Authors: Xiang Xuezhi , Zhang Yuqi , El Saddik Abdulmotaleb
Published: March 2020

Automatic detection of pavement crack is an important task for conducting road maintenance. However, as an important part of the intelligent transportation system, automatic pavement crack detection is challenging due to the poor continuity of cracks, the different width of cracks, and the low contrast between cracks and the surrounding pavement. This study proposes a novel pavement crack detection method based on an end‐to‐end trainable deep convolution neural network. The authors build the network using the encoder–decoder architecture and adopt a pyramid module to exploit global context information for the complex topology structures of cracks. Moreover, they introduce a spatial‐channel combinational attention module into the encoder–decoder network for refining crack features. Further, the dilated convolution is used to reduce the loss of crack details due to the pooling operation in the encoder network. In addition, they introduce a lovász hinge loss function, which is suitable for small objects. They train the authors' network on the CRACK500 dataset and evaluate it on three pavement crack datasets. Among the methods they compare, their method can achieve the best experimental results.

Authors: Chu Zhenzhong , Sun Bo , Zhu Daqi , Zhang Mingjun , Luo Chaomin
Published: March 2020

In this study, a motion control algorithm based on deep imitation reinforcement learning is proposed for the unmanned underwater vehicles (UUVs). The algorithm is called imitation learning (IL) twin delay deep deterministic policy gradient (DDPG) (TD3). It combines IL with DDPG (TD3). In order to accelerate the training process of reinforcement learning, the supervised learning method is used in IL for behaviour cloning from the closed‐loop control data. The deep reinforcement learning employs actor–critic architecture. The actor part executes the control strategy and the critic part evaluates current control strategy. The training efficiency of IL‐TD3 is compared with DDPG and TD3. The simulation results show that the training results of IL‐TD3 converge faster and the training process is more stable than both of them, the convergence rate of IL‐TD3 algorithm during training is about double that of DDPG and TD3. The control performance via IL‐TD3 is superior to PID in UUVs motion control tasks. The average track error of IL‐TD3 is reduced by than PID control. The average tracking error under thruster fault is almost the same as under normal condition.

Published: March 2020

Interleaved DC–DC converters are extensively employed in high‐power applications to reduce input/output current ripple, elements current stress, and improve reliability. In order to eliminate the switching losses in interleaved converters, zero voltage transition (ZVT) technique can be used. This study presents a new compact ZVT cell appropriate for interleaved converters. This cell employs a low number of elements while imposing no extra voltage and current stresses on the converter main semiconductors. The proposed cell is applied to an interleaved boost converter to achieve full soft switching feature. The resulting ZVT interleaved boost converter is completely analysed and its design procedure is provided. Also, the converter is compared with the latest prominent counterparts presented in literature. Besides, its operation and theoretical analysis are validated by a 200 W and 100 kHz prototype. Finally, the proposed ZVT cell is applied to other types of interleaved converters and a family of ZVT interleaved converters is introduced.

Published: March 2020

With the increasing demand for volume reduction and efficiency improvement, very high frequency (VHF) power converters (30–300 MHz) have attracted great interest. Under such high operating frequency conditions, the value and volume of passive components can be greatly reduced, and the power density can be improved. However, many concerns and challenges accompany the increasing operating frequency, such as high switching loss, high magnetic components loss and high driving circuit loss. Including various topologies of the VHF converter, this study reviews the state‐of‐the‐art technology involved in the VHF power converter, also encompassing the inverter stage and matching network stage. Secondly, different magnetic components and semiconductor devices were evaluated under the VHF operating condition. Thirdly, the high‐efficiency driving methods, such as the resonant driving method and self‐resonant driving method, were demonstrated. A guideline for converter design and system optimisation of the VHF converter and related technologies, including all components and systems, is illustrated in this study. Finally, the future research hot spots and challenges have been pointed out as guidance for further advanced VHF power conversion techniques.
High step‐up DC–DC converter with three capacitors clamped circuits for reduced out capacitor stress
Authors: Ai Jian , Lin Mingyao , Liu Tongmin
Published: March 2020

In this study, a novel converter which integrates three capacitor clamped circuits and coupled inductor is proposed for high voltage gain. Compared with classical clamped circuit, these clamped circuits which are composed of one diode and three capacitors are used to improve voltage gain and achieve a continuous input current in this proposed converter. The proposed converter has four different clamped circuits, which can be divided into two types, including horizontal clamped and vertical ways. Moreover, each type of new clamped circuit corresponds to two different clamped circuits. This makes the designer have more selections to recycle the energy stored in leakage inductor. Besides, one of the three capacitors is connected in series with the output capacitor to efficiently reduce the voltage stress across the output capacitor, and voltages of both of them are less than half output voltage. Finally, in these converters, a converter based on three capacitor clamped circuit as a representative is analysed in detail. A prototype circuit is established in the laboratory to demonstrate the performances of this converter.
Stand‐alone multiple input photovoltaic inverter for maximum power extraction and voltage regulation under mismatched atmospheric conditions
Authors: Hema Chander Allamsetty , Sahu Lalit Kumar , Ghosh Subhojit
Published: March 2020

In this study, a single‐phase multi‐input photovoltaic (PV) inverter has been proposed for simultaneously achieving maximum power extraction and load voltage regulation under various operating scenarios involving weather intermittency and dynamic loading. This is achieved by maintaining the PV modules in series for similar atmospheric conditions and by allowing isolated operation of individual modules during mismatched atmospheric conditions among different modules. The weather‐dependent operation of the modules allows efficient extraction of maximum power from all the modules by avoiding the modules to operate at the least maximum power point (MPP) among them, which has been a limitation of classical techniques aiming at MPP with multiple modules. A comprehensive analysis of the proposed inverter topology and its associated synchronous reference frame‐based control scheme has been carried out by considering a wide range of operating scenarios in terms of (i) maintaining the operation closer to MPP under varying irradiance levels and temperature; (ii) regulated output voltage for load variation. The appropriateness of the scheme has been compared with the existing state‐of‐the‐art topologies. In addition to the MATLAB simulation, validation has been carried out on a 300 W laboratory prototype.
