Technology Demonstration of ATR with a Ramjet Test Facility

To investigate characteristics of an Air Turbo Ramjet (ATR) propulsion system in flight conditions, an ATR technology demonstrator was developed and Direct Connect (DC) test was conducted with simulated flight conditions from sea level to 12km (40kft) in altitude and Mach 0 to 3.0 in flight speed. The compression ratio of the turbo unit exceeded 1.0 even in high Mach number conditions, augmenting the thrust mainly generated by the ram combustor. The demonstrator still generated sufficient thrusts in subsonic flight conditions, indicating the ram combustor maintained reasonable efficiencies with a help of compression of the incoming air by the turbo unit. The compressor was able to be driven at the maximum mechanical rotation speed at any DC test conditions. Thus, capability of ATR propulsion was successfully demonstrated.
Circuits for Blind ADC-based CDRs and Frequency Detectors

This thesis presents three contributions in the area of clock and data recovery (CDR). Two of these three contributions focus on the design of frequency detection mechanisms for reference-less half-rate clock and data recovery circuits, while the third one focuses on the design of blind ADC-based CDRs. While conventional CDR architectures for phase and frequency detection are dual loop, the interaction between the frequency detection loop and the phase detection loop can interfere with phase locking. Furthermore, the frequency detector, typically deactivated after lock, occupies area. This thesis introduces two new architectures for reference-less CDRs which perform frequency detection by adjusting the phase error of the phase detector. This enables the phase detector to deal with frequency offset, as well as phase offset. The feasibility of these two 10Gb/s CDRs are demonstrated through chip fabrications in Fujitsu 65nm CMOS technology and measurement results. The third contribution of this thesis is in the area of blind ADC-based CDRs. While the design simplicity of these CDRs significantly reduces their time to market, their high power consumption limits their application. This thesis studies the architecture of these CDRs with the goal of minimizing their power consumption. We will show that for ii a given analog power consumption, the optimum oversampling ratio is 2.8 (≈3). The digital CDR is also redesigned to lower the power consumption of digital equalization. A 5Gb/s CDR was fabricated in Fujitsu 65nm CMOS technology and measurement results show a factor of 2 of power reduction, with improved performance.
Acupuncture treatment of hypertension with insomnia

Abstract Introduction: Hypertension patients often suffered from insomnia problems which lowered the quality of life. Studies have shown that acupuncture is effective to treat perimenopausal and cancer-related insomnia. However, there is a lack of randomized controlled trials to support the effectiveness of acupuncture on insomnia of hypertension patients. Methods and analysis: This study is a randomized, double-blind (patients and evaluators), and placebo-controlled clinical trial to investigate the effect of acupuncture in hypertension patients’ insomnia management. We will recruit 158 hypertension patients suffering from insomnia in Bao’an People's Hospital, Shenzhen and randomly assign them into treatment group (antihypertensive drugs + acupuncture) and control group (antihypertensive drugs + sham acupuncture) in a 1:1 ratio. The patients will receive acupuncture 3 times a week for 12 weeks, and then a 6-months follow-up will be conducted after the treatment. The primary outcome is the Pittsburgh Sleep Quality Index. The secondary outcomes include sleep parameters, blood pressure dropping, sleeping pill dosage, Rating Depression Scale score, and Self-Rating Anxiety Scale score. The primary outcome will be evaluated at baseline, 4, 8, and 12 weeks, and 1, 3, and 6 months following the end of treatment. The secondary outcomes will be assessed at baseline and 12 weeks of the treatment period.
Rapid Quality Evaluation of Camellia Oleifera Seed Kernel Using a Developed Portable NIR With Optimal Wavelength Selection

Moisture content is one of the factors measured to evaluate the quality of Camellia oleifera seeds. High quality C. oleifera seeds used for trading must have a low moisture content, specifically not more than 15% on a dry basis (db). Moisture content analysis requires a prolonged laboratory investigation so that the development of fast and effective determination methods is helpful. The objective of this paper was to develop a low-cost portable NIR reflectance spectrometer collaborating with an android application for the rapid prediction of the moisture content in C. oleifera seeds. To calibrate the prediction model, an effective chemometric algorithm, based on partial least squares regression was established, and models based on wavelength selection algorithms such as backward interval partial least squares (biPLS) and partial least squares coupled with variable importance projection (VIP-PLS) were implemented as an improved version of PLS. Both algorithms (biPLS and VIP-PLS) improved the predictive performance and accuracy of the model. The experimental results showed that the biPLS model with the 1st derivative transformation provided the best prediction for measuring the moisture content of C. oleifera seeds with a coefficient of determination (R2) value of 0.927, standard error of prediction (SEP) of 0.848%db, bias of −0.067%db, function slope of 1.005, and ratio of performance deviation (RPD) of 3.696. Finally, the device was tested according to the ISO 12099:2017(E) standard and confirmed the reliability of the device for in-field use.
EFFECT OF BASKETBALL SHOES OF DIFFERENT WEIGHTS ON PERFORMANCE IN A GAME-LIKE SCENARIO

Lighter shoes have been shown to improve running economy; however this same phenomenon has not been investigated in basketball shoes. The purpose of this study was to investigate the physiological effects of basketball shoes of different masses during an on-court, game like scenario. Twelve male basketball players participated in this study. One shoe that was modified to have three different masses (Light, Medium, and Heavy) was evaluated in this study. Subjects completed a basketball-specific 20 minute fieldbased work protocol (Basketball-20) in each shoe on three different days while five physiological variables of interest were collected. The light shoe condition resulted in significantly lower oxygen consumption, ventilation, and rate of energy expenditure than the medium and heavy conditions.
Reinforced Palmprint Reconstruction Attacks in Biometric Systems

Biometric signals can be acquired with different sensors and recognized in secure identity management systems. However, it is vulnerable to various attacks that compromise the security management in many applications, such as industrial IoT. In a real-world scenario, the target template stored in the database of a biometric system can possibly be leaked, and then used to reconstruct a fake image to fool the biometric system. As such, many reconstruction attacks have been proposed, yet unsatisfactory naturalness, poor visual quality or incompleteness remains as major limitations. Thus, two reinforced palmprint reconstruction attacks are proposed. Any palmprint image, which can be easily obtained, is used as the initial image, and the region of interest is iteratively modified with deep reinforcement strategies to reduce the matching distance. In the first attack, Modification Constraint within Neighborhood (MCwN) limits the modification extent and suppresses the reckless modification. In the second attack, Batch Member Selection (BMS) selects the significant pixels (SPs) to compose the batch, which are simultaneously modified to a slighter extent to reduce the matching number and the visual-quality degradation. The two reinforced attacks can satisfy all the requirements, which cannot be simultaneously satisfied by the existing attacks. The thorough experiments demonstrate that the two attacks have a highly successful attack rate for palmprint systems based on the most state-of-the-art coding-based methods.
Triply Periodic Channels Enable Soft Pneumatic Linear Actuator with Single Material and Scalability

In this letter, we propose a new class of soft pneumatic linear actuators with single-material, uniaxial deformation, high energy density, and scalability, purely based on periodic curved air channels. The shape of channels is implicitly parameterized by modified triply periodic minimal surfaces (mTPMS) that partition the space into two intertwined sub-domains of open-cell topology. The period ratio of mTPMS that controls the stiffness along primary directions is identified as a key design variable, by tuning which the actuator may deliver linear, areal, and volumetric actuation modes. This work mainly investigates the linear motion mode. The actuator's deformation behavior and energy density have no scale effect when the gravity is ignored, and thus the optimal design is readily scalable. Based on a unit cell with periodic boundary conditions, we develop a finite element analysis model to predict the effect of the period ratio and the thickness-related isovalue on the actuator's deformation behavior, and further perform parametric optimization. The mTPMS-based actuators of complex geometry are 3D printed and exhibit linear motions up to nominal strain of 48.6%, blocking force of 45.9 N, and energy density of 1.25 kJ/m^3. We demonstrate a preliminary application of the linear actuators as artificial muscles by an antagonistic arrangement. This work explores the geometry-actuation integrated design of pneumatic metamaterials, and represents an important step toward the blueprint of ‘`materials as machines’' for applications envisioned across different scales.
Construction of Depression Knowledge Graph Based on Biomedical Literature

Depression is a common mood disorder, which has the characteristics of high prevalence, high recurrence rate, high disability rate and high mortality rate. There are a large number of medical literature on depression, but the number is large and disorderly, which will undoubtedly increase the burden of biomedical researchers and medical workers to obtain knowledge, and is not conducive to the research on the pathogenesis and treatment of depression. Therefore, we construct a knowledge graph of depression based on biomedical literature to assist the study of depression. We use medical abstracts as the main data source and extract knowledge from them by using SemRep, which is a biomedical information extraction system. Secondly, we use another information extraction tool named OpenIE to correct the data extracted by SemRep. Then, by fusing the extracted knowledge with structured data extracted from SemMedDB, we finally get 8,840 triples which include 3,055 entities and 30 relationships. We store them into the graph database Neo4j to visualize the knowledge graph.
Performance analysis of a basin-type solar still during harmattan

Abstract. This study investigates the variational effect of climate factors on the productivity of a basin-type solar still during the harmattan season under the tropical savanna climate. The study was extended to examine the influences of selected climatic, operational, and design (COD) parameters on productivity. Additionally, the efficiency of solar still in removing water impurities during harmattan was also investigated. Explorative data and statistical analysis, and laboratory testing methods were used for these investigations. Results show that seasonal effects of harmattan can either increase or lower productivity. The effect of wind speed on productivity was not clearly defined during the harmattan season. Although high irradiation is essential for increased productivity, its effect is modified by other factors. Water temperature is the most significant to productivity amongst selected factors studied via the design of experiment (DOE). Moreover, the effect of harmattan on the water quality produced was not established. The main contribution of this work is the insights generated for both qualitative and quantitative reliability performance of a basin-type solar still under prevailing climate conditions.
Product Innovativeness Strategy with Crowdsourcing

This study focuses on the manufacturer’s strategy of product innovation when a set of potential consumers are involved in product innovation through crowdsourcing. Two models are built for developing incremental and radical products to capture the manufacturer’s optimal strategy in a supply chain which includes one supplier, one manufacturer, and some potential consumers. In addition, the effort compensation mechanism has been designed to improve the profits of the manufacturer and supplier, and consumer surplus. Finally, the innovativeness strategy is explored based on the manufacturer providing compensation for crowdsourcing consumers. The results show the following: (1) if the degree of preference dispersion is low, the percentage of crowdsourcing consumers is large, or the degree of knowledge spillover is high, the manufacturer prefers radical innovation. It also implies the negative relationship between the manufacturer’s profit and innovation level. Otherwise, the manufacturer prefers incremental innovation, which implies the positive correlation between the manufacturer’s profit and innovation level; (2) under the optimal product innovativeness strategy, supplier’s profit and consumer surplus also are improved; (3) under certain conditions, offering compensation for crowdsourcing consumers is Pareto improvement strategy for the manufacturer, the supplier, and crowdsourcing consumers.
Continuous and intermittent theta burst stimulation to the visual cortex do not alter GABA and glutamate concentrations measured by magnetic resonance spectroscopy

Theta burst stimulation (TBS), a form of repetitive transcranial magnetic stimulation (rTMS), uses repeated high‐frequency bursts to non‐invasively modulate neural processes in the brain. An intermittent TBS (iTBS) protocol is generally considered “excitatory,” while continuous TBS (cTBS) is considered “inhibitory. ” However, the majority of work that has led to these effects being associated with the respective protocols has been done in the motor cortex, and it is well established that TMS can have variable effects across the brain.
A random graph of moderate density

We analyse a randomly growing graph model in which the average degree is asymptotically equal to a constant times the square root of the number of vertices, and the clustering coefﬁcient is rather small. In every step, we choose two vertices uniformly at random, check whether they are connected or not, and we either add a new edge or delete one and add a new vertex of degree two to the graph. This dependence on the status of the connection chosen vertices makes the total number of vertices random after n steps. We prove asymptotic normality for this quantity and also for the degree of a ﬁxed vertex (with normalization n 1 / 6 ). We also analyse the proportion of vertices with degree greater than a ﬁxed multiple of the average degree, and the maximal degree.
Mechanical Amplifier for Giant Magnetostrictive Materials and Piezoelectric Materials

Giant magnetostrictive materials( GMM) and piezoelectric( PZT) materials have been significantly used in commercial products as well as military applications,with high energy density,long life,and electric drive advantages. Although these materials have high force and large bandwidth capabilities,their use has been limited due to their small stroke. The use of mechanical amplifiers is an effective way to overcome this problem. This article will review recent literatures of three main kinds of design methodologies of mechanical amplifiers for GMM and PZT materials. It is proposed that the flexure-hinged displacement amplifiers,Hydraulic displacement amplifiers and Flexural frame displacement amplifiers are suitable for piezoelectric materials,miro-electro-mechanical systems and Giant Magnetostrictive materials,respectively.
Continuous Scoring of Depression From EEG Signals via a Hybrid of Convolutional Neural Networks

Depression score is traditionally determined by taking the Beck depression inventory (BDI) test, which is a qualitative questionnaire. Quantitative scoring of depression has also been achieved by analyzing and classifying pre-recorded electroencephalography (EEG) signals. Here, we go one step further and apply raw EEG signals to a proposed hybrid convolutional and temporal-convolutional neural network (CNN-TCN) to continuously estimate the BDI score. In this research, the EEG signals of 119 individuals are captured by 64 scalp electrodes through successive eyes-closed and eyes-open intervals. Moreover, all the subjects take the BDI test and their scores are determined. The proposed CNN-TCN provides mean squared error (MSE) of 5.64±1.6 and mean absolute error (MAE) of 1.73±0.27 for eyes-open state and also provides MSE of 9.53±2.94 and MAE of 2.32±0.35 for the eyes-closed state, which significantly surpasses state-of-the-art deep network methods. In another approach, conventional EEG features are elicited from the EEG signals in successive frames and apply them to the proposed CNN-TCN in conjunction with known statistical regression methods. Our method provides MSE of 10.81±5.14 and MAE of 2.41±0.59 that statistically outperform the statistical regression methods. Moreover, the results with raw EEG are significantly better than those with EEG features.
Fabrication of a Covalent Triazine Framework Functional Interlayer for High-Performance Lithium–Sulfur Batteries

The shuttling effect of polysulfides is one of the major problems of lithium–sulfur (Li–S) batteries, which causes rapid capacity fading during cycling. Modification of the commercial separator with a functional interlayer is an effective strategy to address this issue. Herein, we modified the commercial Celgard separator of Li–S batteries with one-dimensional (1D) covalent triazine framework (CTF) and a carbon nanotube (CNT) composite as a functional interlayer. The intertwined CTF/CNT can provide a fast lithium ionic/electronic transport pathway and strong adsorption capability towards polysulfides. The Li–S batteries with the CTF/CNT/Celgard separator delivered a high initial capacity of 1314 mAh g−1 at 0.1 C and remained at 684 mAh g−1 after 400 cycles−1 at 1 C. Theoretical calculation and static-adsorption experiments indicated that the triazine ring in the CTF skeleton possessed strong adsorption capability towards polysulfides. The work described here demonstrates the potential for CTF-based permselective membranes as separators in Li–S batteries.

First evidence of insecticidal potential of molecules produced during the parasitic phase of the endoparasitoid Cotesia flavipes

Immature endoparasitoids develop inside their hosts. Consequently, endoparasitoids need to circumvent the action of the immune system and reprogram the physiology of their hosts to develop successfully. For this, parasitoids release host regulation‐related molecules into their host’s hemolymph produced by the parasitoid itself or expressed in specific host cells infected by parasitoid symbiotic viruses. In addition to their roles in host regulation, these molecules may also present biotechnological potentials, such as for insecticidal purposes in crop protection. We performed a survey for the biotechnological potential of compounds present in the hemolymph serum with and without circulating cell contents of Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae) as insecticides in feeding assays. Hemolymph serum from D. saccharalis larvae at 6 days after the start of the parasitism with and without circulating cell contents were collected and spread over artificial diet or over sugarcane leaves for feeding assays with D. saccharalis neonates. Hemolymph serum with or without circulating cell contents from non‐parasitized D. saccharalis larvae at the same age were used as controls. Subsequently, hemolymph serum plus circulating cell contents was fractioned using molecular filters and fractions with different molecular weight range were used for feeding assays with D. saccharalis neonates. Feeding larvae with leaf disks amended with hemolymph serum plus circulating cell contents from parasitized hosts resulted in an increase of ca. 30% in the mortality of D. saccharalis neonates. After fractioning hemolymph serum plus circulating cell contents, feeding assays with the >100 or 3–10 kDa fractions did not result in the previously observed increase in larval mortality, but resulted in a reduction of leaf consumption by neonates. Finally, we selected a parasitism‐specific protein band observed in the hemolymph >100 kDa fraction for mass spectrometry identification. This parasitism‐specific protein was similar to hymenopteran apolipophorins‐I. We conclude that there is an insecticidal potential in the hemolymph serum plus circulating cell contents of D. saccharalis larvae parasitized by C. flavipes and further investigations will be performed to identify, characterize, and uncover the biotechnological application of these molecules.
