Published: November 2019

AbstractByproducts such as orange peel have potential uses because of their bioactive compounds, which are important for their potential to reduce the risk factors of diseases caused by aging. The lack of effective techniques and the high levels of pollution produced by the conventional extraction of bioactive compounds using organic solvents have highlighted the need to enhance the ‘green chemistry’ trend. This study evaluates the use of ultrasound to extract bioactive compounds from orange peel. The antioxidant capacity, phenolic content, ascorbic acid, total carotenoids, and HPLC profile of phenolic compounds from orange peel extracts were obtained by a physicochemical evaluation. The results demonstrate that the optimal conditions for the ultrasound-assisted extraction of bioactive orange peel compounds were a power of 400 W, a time of 30 min, and 50% ethanol in water. These conditions were used to obtain a total carotenoid concentration of 0.63 mg ß-carotene/100 g, vitamin C concentration of 53.78 mg AA/100 g, phenolic concentration of 105.96 mg GAE/100 g, and antioxidant capacity of ORAC = 27.08 mM TE and TEAC = 3.97 mM TE. The major phenolic compound identified in all orange peel extracts was hesperidin, with a maximum concentration of 113.03 ± 0.08 mg/100 g.
Emerging roles of the long non-coding RNA 01296/microRNA-143-3p/MSI2 axis in development of thyroid cancer

Published: November 2019

Abstract
Thyroid cancer (TC) is an endocrine malignancy with rising incidence. Long non-coding RNAs (lncRNAs) can serve as diagnostic and prognostic biomarkers for TC. Thus, we studied roles of LINC01296 in TC progression. Initially, the Gene Expression Omnibus (GEO) database was used to detect the differentially expressed genes in human TC samples and the potential mechanism. Expression of LINC01296 and miR-143-3p in TC tissues and cells was measured. The transfection of TC cells was conducted with si-LINC01296, si-Musashi 2 (MSI2), mimic or inhibitor of miR-143-3p to determine their effects on TC cell proliferation, migration, invasion, apoptosis and the AKT/STAT3 signaling pathway. Finally, in vivo assay was performed to verify role of miR-143-3p in tumorigenesis of TC cells in nude mice. LINC01296 was predicted to bind to miR-143-3p to modulate MSI2 expression, thus regulating the occurrence and development of TC. LINC01296 was up-regulated, while miR-143-3p was down-regulated in TC cells and tissues. LNC01296 specifically bound to miR-143-3p and MSI2 was a target of miR-143-3p. Besides, LINC01296 silencing or miR-143-3p overexpression inhibited migration, invasion, proliferation and advanced apoptosis of TC cells. Additionally, silenced LINC01296 or overexpressed miR-143-3p reduced phosphorylated STAT3/STAT3, phosphorylated AKT/AKT, B-cell lymphoma-2 (Bcl-2) and CyclinD1 levels but elevated BCL2-associated X (Bax), Cleaved Caspase3 and Caspase3 levels. Also, tumorigenesis of TC cells in nude mice was inhibited with the silencing of LINC01296. In summary, LINC01296/miR-143-3p/MSI2 axis regulated development of TC through the AKT/STAT3 signaling pathway.

Authors: de Ronde-Brons Inge , Soede Wim , Dreschler Wouter 
Published: November 2019

Purpose
The aim of the study was to evaluate the application of a modified version of the Amsterdam Inventory for Auditory Disabilities and Handicap to inventory self-reported hearing difficulties pre and post hearing aid fitting in 6 dimensions: detection, speech in silence, speech in noise, localization, discrimination, and noise tolerance.

Method
Questionnaires pre and post hearing aid fitting were collected during regular practice of hearing aid provision. Data of 740 subjects are presented; 337 already used hearing aids, and 403 were new users.

Results
Group-averaged scores improved due to hearing aid fitting for all 6 dimensions. Based on a criterion previously defined for the Amsterdam Inventory for Auditory Disabilities and Handicap questionnaire, 66% of subjects had a significant individual improvement in sum score. Experienced users showed lower improvement in scores, whereas their aided prescores were, on average, not better than the (unaided) score of 1st users.

Conclusions
The questionnaire can be applied as a structured approach to inventory hearing problems in 6 dimensions prior to hearing aid fitting and to systematically evaluate the effects of hearing aid fitting after a trial period. The data presented here can serve as normative data for comparison of individual subjects in clinical practice.
On the cognitive grounding of agent-deprofiling constructions as a case of pretense constructions
Authors: Ruiz de Mendoza Ibáñez Francisco J. , Miró Sastre Ignasi 
Published: November 2019

Abstract

Agent-deprofiling constructions have the function of drawing the language user’s attention to the
non-agentive elements of a predication, while endowing one of these elements with agent-like qualities. Members of this family are
the inchoative, middle, instrument-subject, location-subject, and cause-subject constructions.
These constructions have been discussed in the literature, especially in projectionist accounts of language, without adequately
accounting for their relatedness, which in our view can best be done by investigating their grounding in cognition. The present
article addresses this issue by considering agent-deprofiling constructions as belonging to the class of what we term
pretense constructions. Pretense constructions provide non-descriptive, or re-construed, representations of
states, situations, or events. Because of their re-construed nature, which involves metaphor and/or metonymy, in these
configurations there is no one-to-one match between the semantic and syntactic functions of their elements. We discuss how this
reorganization of the semantic and syntactic function of constructional elements produces specific meaning implications that can
be motivated by underlying metaphoric and metonymic shifts, sometimes working in cooperation.

Authors: Ravagli Enrico , Mastitskaya Svetlana , Thompson Nicole , Aristovich Kirill , Holder David 
Published: November 2019

Abstract

Objective: The main objective of this study was to investigate which injection pattern led to the best imaging of fascicular compound activity in fast neural EIT of peripheral nerve using an external cylindrical 2  ×  14-electrodes cuff. Specifically, the study addressed the identification of the optimal injection pattern and of the optimal region of the reconstructed volume to image fascicles. Approach: The effect of three different measurement protocol features (transversal/longitudinal injection, drive electrode spacing, referencing configuration) over imaging was investigated in simulation with the use of realistic impedance changes and noise levels. Image-based metrics were employed to evaluate the quality of the reconstructions over the reconstruction domain. The optimal electrode addressing protocol suggested by the simulations was validated in vivo on the tibial and peroneal fascicles of rat sciatic peripheral nerves (N  =  3) against MicroCT reference images. Main results: Injecting current transversally, with spacing of  ⩾4 electrodes apart (⩾100°) and single-ring referencing of measurements, led to the best overall localization when reconstructing on the edge of the electrode array closest to the reference. Longitudinal injection protocols led to a higher SNR of the reconstructed image but poorer localization. All in vivo EIT recordings had statistically significant impedance variations (p   <  0.05). Overall, fascicle center-of-mass (CoM) localization error was estimated at 141  ±  56 µm (−26  ±  94 µm and 5  ±  29° in radial coordinates). Significant difference was found (p   <  0.05) between mean angular location of the tibial and peroneal CoMs. Significance: This study gives the reader recommendations for performing fast neural EIT of fascicular compound activity using the most effective protocol features.

HOMOM/PE Hybrid Algorithm Based Calculation on Ground-Wave of the HF Antennas over Irregular Terrain
Authors: Wang Li-feng , Zhang Zhi-gang 
Published: November 2019

Abstract
The parabolic equation model usually uses a gaussian pattern to fit the actual antenna’s pattern in free space to set the initial field, and then uses the image theory to deal with the effect of ground on the antennas. However, this method of setting the initial field cannot consider the specific HF antenna, and the image theory is only applicable to the radio wave propagation of antennas working in the microwave bands and above. The HF antenna is erected low, and the irregular terrain or the buildings around the antenna and their media parameters will affect the current distribution on the antenna, resulting in a large difference with the radiation pattern in the free space. The traditional method of fitting the pattern is no longer accurate. Aiming at the problem of radio wave propagation of HF antennas in the actual installation environment by parabolic equation method, a hybrid algorithm based on higher order-method of moment and parabolic equation method (HOMOM-PE) is proposed. The hybrid algorithm divides the whole calculation region into two regions, which is the inner zone and the outer zone. The inner zone is the zone that has a great influence on the antenna current distribution. In this area, HOMOM is used to model the antenna and the terrain together, and the influence of the complex terrain near the antenna on the antenna is strictly calculated. The PE algorithm is used to calculate the long-distance propagation, and the initial field data is derived from the electromagnetic vector distribution calculated in the inner region. The hybrid algorithm combines the antenna radiation and the wave propagation directly, which solves the problem of the initial field setting of the actual HF antenna under the complicated terrain conditions.
Isolation Improvement of an Overlapped Two-element MIMO Antenna
Authors: Li Wenchao , Qian Kewei 
Published: November 2019

Abstract
An overlapped two-element antenna structure with excellent compactness is proposed. Extraordinarily strong mutual coupling is effectively mitigated by a decoupling network with simple coupled microstrip lines connected to the antennas in shunt. Simulation example and results are demonstrated. The isolation improvement is better than 8 dB (from about 2 dB to over 10 dB) in most of the Wi-Fi 2.4 GHz band. Four lumped components networks are utilized to maintain the good impedance matching before and after decoupling, and the return loss is higher than 7 dB over the band of interest. Remarkable decrease in envelope correlation coefficient (ECC) in most of the working band is achieved. All these performances prove the presented antenna structure and decoupling scheme a promising option for those mobile terminals and wireless communication devices which have high data rate and compact volumes.

Abstract
Satellite laser communication technology is a communication method that uses laser beam as information transmission carrier to transmit information data in space. It has many advantages such as large communication capacity, long transmission distance, high bandwidth, no spectrum permission, etc,widely used at present. The beacon light direction of its typical satellite laser communication system is realized by rough tracking servo turntable platform carrying optical components, so,there are a series of shortcomings such as turntable vibration, corner error and system inertia etc. Currently, a new technology, Non-Mechanical Beam Steering (NMBS) technology, in mid-wave infrared (MWIR) which has emerged, is expected to break through above shortcomings and provide possibilities for the transmission of beacon light in satellite laser communication. This paper focuses on the application of non-mechanical beam pointing technology in satellite laser communication system. We objectively analyzed the basic principles of the Non-Mechanical Beam Steering chip work, and the feasibility of using Non-Mechanical Beam Steering to transmit beacon light in satellite laser communication theoretically. It will open up a new way for the development of microsatellite laser communication technology in the future.

Secondly, the route time difference theorem is proposed, and the calculation steps and rules of the delay analysis method considering the logical relationship between engineering processes are given. Finally, the substation main structure construction project is selected as an example analysis, and compared with other methods, which effectively proved that the validity and feasibility of the proposed delay analysis method. The method of delay responsibility allocation proposed in this paper also provides ideas and directions for the subsequent research on delay assignment of similar construction projects.

Published: November 2019

Abstract
As an important weapon, missiles cannot be ignored in its fighting capacity. Therefore, the performance testing of the missile is particularly important. The hardware in the loop simulation test using missile test equipment on the ground can reduce the cost and improve the utilization rate; it is of great significance for the development of national defence construction. In the process of missile testing, the parts under the force of deformation will reduce the accuracy of the device, therefore the light pipe support needs sufficient strength and stiffness. In this paper, the finite element method was used to analyse the structure of the optical tube support seat, and the orthogonal test was used to optimize it. The test results were analysed by the range and variance to find out the optimal level combination and the significant influence of each factor in the result. At end, the appropriate structure of the program was determined. Comparing with the original structure, the strength and rigidity of the optical tube support seat have been greatly improved. Device accuracy has also been improved.

Published: November 2019

Abstract
In order to meet the needs of large plane’s flatness error measurement and aim at the time-consuming, laborious, expensive and inefficient problems, a flatness error measurement system of large plane based on laser dots was designed. The measurement system scanned the plane by the distance sensor which was driven by a double degree-of-freedom rotating platform. The Euler angles of distance sensor and the displacement data between the distance sensor and the measured plane were collected by the data acquisition card. Then the measurement system obtained the spatial coordinate values of laser dots through data processing. Eventually, the actual surface was reconstructed and the flatness error was calculated. The measurement results showed that the system could accurately reflect the actual surface and had great significance in promoting the industrial application of large plane’s flatness error detecting device.

Published: November 2019

Abstract
New energy generation has the characteristics of nonlinearity, randomness and fluctuation, which may cause many kinds of power quality problems, such as harmonics, voltage fluctuation, frequency offset and phase jump, so synchronization technology under disturbance becomes one of the key factors. At present, there are many summaries about three-phase phase-locked loop (PLL), three-phase frequency-locked loop (FLL) and single-phase PLL, but few summaries about single-phase FLL. Therefore, single-phase FLL based on second-order generalized integrator (SOGI) is summarized in this paper, including SOGI-FLL, cascaded SOGI-FLL (CSOGI-FLL) and multiple SOGI-FLL (MSOGI-FLL).The simulation models are established in Matlab/Simulink. The performance of FLLs are compared with square error integral index (ISE), maximum frequency deviation and adjusting time in ideal condition, voltage sag condition, frequency offset condition, phase jump condition, the amplitude of fluctuation is used to compare the four PLLs under harmonic condition. The application scopes of different FLLs are summarized to flexible selection in actual working condition.
