Parallel Operation of Voltage Source Converters without Filter Inductors: Control of the Circulating Current

Scalable large-scale power systems can be managed by paralleling of multiple power converters, possibly arranged in interleaved configurations. State-of-the-art in reduction of the circulating current indicates the ubiquitous use of filter inductors, which are placed at each parallel converter output. This paper presents a new control algorithm to remove those filters, relying only on the natural parasitic inductance at each connection point. Multiple cells in parallel are modeled to investigate the transient behavior of the load signals and their group dynamics in case of a large number of units. A two-step control strategy is proposed: a narrow-bandwidth communication interface is used to synchronize coarsely the units, then a high-speed closed-loop control on the converter current tracks the difference in samples taken by the Double Edge Sampler (DES). Correction is achieved by means of high-resolution parametric delays, cascaded to the traditional PWM modulator. Each converter controls its own current without the need of information from his neighbors. The potential of this technology is envisioned in the automotive field, where modular powertrains can be designed for different vehicle targets. The effects of the proposed approach can improve power per unit of volume and weight, thanks to the removal of the bulky output filters.
Image Synthesis With Efficient Defocus Blur for Stereoscopic Displays

Image synthesis for stereoscopic displays shall carefully control its depth of field to enhance perception while reduce visual fatigue due to accommodation-vergence mismatch. Existing approaches suffer from either lower quality due to occluding contour error, or high computational complexity. To meet above demands, this paper proposes a perceptual oriented defocus blur that reduces complexity with the depth layer processing and improves quality with transparency degree oriented superposition and edge enhancement. The simulation results show that the proposed approach has better quality than the conventional defocus blur methods and achieves similar quality compared to the deep learning based methods but with much lower complexity.
Inventory Placement Mapping using Bluetooth Low Energy Beacon Technology for Warehouses

Inventory management is the key to an efficient supply chain. Numerous kinds of inventories are stored in a warehouse where locating goods can be troublesome for the employees. Specifically, in corrugated box company, inventories of paper rolls are placed in a huge warehouse where there are hundreds of paper rolls stock ranging from different weights and sizes. Finished goods are also stored in a warehouse awaiting delivery, placed in between hundreds of other customers' orders where delivery schedule varies from one another. Thus, the positioning of the goods is not permanent and is changing along with the incoming orders. The research aims to explore BLE beacons for the most effective solution in handling inventory placement problems. Common tracking technologies for inventories include barcodes, QR codes, and RFID. The fourth industrial revolution drives the application of IoT, Bluetooth low energy (BLE) beacons are one of the examples in the area. It is the successor of the previous Bluetooth technology, which is more eminent in energy saving. In warehouses, BLE beacons are positioned to determine zone mapping in organizing the floor plan, assists in indoor navigation for guiding employees, and support asset tracking with beacon tags for identification and goods tracing.
Insidious Transmission of a Stress-Related Neuroadaptation

Stress is highly pervasive in humans, impacting motivated behaviors with an enormous toll on life quality. Many of the effects of stress are orchestrated by neuropeptides such as corticotropin-releasing factor (CRF). It has previously been shown that in stress-naïve male mice, CRF acts in the core of the nucleus accumbens (NAc) to produce appetitive effects and to increase dopamine release; yet in stress-exposed male mice, CRF loses its capacity to modulate NAc dopamine release and is aversive. In the current research, we tested whether this effect is comparable in females to males and whether the neuroadaptation is susceptible to social transmission. We found that, like in males, CRF increased dopamine release in stress-naïve but not stress-exposed female mice. Importantly, this persistent physiological change was not accompanied by overt behavioral changes that would be indicative of depression- or anxiety-like phenotype. Nonetheless, when these mice were housed for 7 days with stress-naïve conspecifics, the cage mates also exhibited a loss of dopamine potentiation by CRF. These data demonstrate the asymptomatic, yet pervasive transmission of stress-related neuroadaptations in the population.
Performance Analysis and Resource Allocations for a WPCN With a New Nonlinear Energy Harvester Model

Wireless powered communication networks (WPCNs) are commonly analyzed by using the linear energy harvesting (EH) model. However, since practical EH circuits are non-linear, the use of the linear EH model gives rise to distortions and mismatches. To overcome these issues, we propose a more realistic, nonlinear EH model. The model is based upon the error function and has three parameters. Their values are determined to best fit with measured data. We also develop the asymptotic version of this model. For comparative evaluations, we consider the linear and rational EH models. With these four EH models, we investigate the performance of a WPCN. It contains a multiple-antenna power station (PS), a signal-antenna wireless device (WD), and a multiple-antenna information receiving station (IRS). The WD harvests the energy broadcast by the PS in the PS-WD link, and then it uses the energy in the WD-IRS link to transfer information. We analyze the average throughput of delay-limited and delay-tolerant transmission modes as well as the average bit error rate (BER) of binary phase-shift keying (BPSK) and binary differential phase-shift keying (BDPSK) over the four EH modes. As well, we derive the asymptotic expressions for the large PS antenna case and the effects of transmit power control. Furthermore, for the case of multiple WDs, we optimize energy beamforming and time allocation to maximize the minimum rate of the WDs. Finally, the performances of four EH models are validated by Monte-Carlo simulations.
Gender Matters: Workplace Bullying, Gender, and Mental Health

The aim of this study was to examine the role of gender in the process of workplace bullying. In particular, we examined how gender affects reported prevalence rates and health consequences of bullying. In addition, we pay particular attention to if the measurement method – self-labelling or behavioural experience methods – affects potential gender differences. A longitudinal study, with two measurement points 18 months apart, was conducted in Sweden (n = 1854 at T1; n = 1096 at T2). It was a probability sample out of a population of all 3.3 million people in Sweden working at workplaces with ten or more employees. The results showed a slightly higher tendency for women to self-label as bullied (8% vs. 6%), while a higher proportion of men than women could be labelled as bullied based on the negative acts they had been exposed to (21% vs. 14%). Exposure to negative acts was associated with more subsequent mental health problems for both men and women, whereas self-labelling was associated with mental health problems for men only. Mental health problems at baseline also increased the risk of bullying for both men and women; however, the measurement method affected if the effect was stronger for men or women. Overall, the study advances our understanding of the role of gender in bullying, in particular highlighting the importance of the measurement method for understanding such gender differences.
Hyperspectral Unmixing Via Nonconvex Sparse and Low-Rank Constraint

In recent years, sparse unmixing has attracted significant attention, as it can effectively avoid the bottleneck problems associated with the absence of pure pixels and the estimation of the number of endmembers in hyperspectral scenes. The joint-sparsity model has outperformed the single sparse unmixing method. However, the joint-sparsity model might cause some aliasing artifacts for the pixels on the boundaries of different constituent endmembers. To address this shortcoming, researchers have developed many unmixing algorithms based on low-rank representation, which makes good use of the global structure of data. In addition, the high mutual coherence of spectral libraries strongly affects the applicability of sparse unmixing. In this study, adopting combined constraints imposing sparsity and low rankness, a novel algorithm called nonconvex joint-sparsity and low-rank unmixing with dictionary pruning is developed In particular, we impose sparsity on the abundance matrix using the <inline-formula><tex-math notation="LaTeX">$\ell _{2,p}$</tex-math></inline-formula> mixed norm, and we also employ the weighted Schatten <inline-formula><tex-math notation="LaTeX">$p$</tex-math></inline-formula>-norm instead of the convex nuclear norm as an approximation for the rank. The key parameter <inline-formula><tex-math notation="LaTeX">$p$</tex-math></inline-formula> is set between 0.4 and 0.6, and a good quality sparse solution is generated. The effectiveness of the proposed algorithm is demonstrated on both simulated and real hyperspectral datasets.
Dynamic Wrist Flexion and Extension Fatigue Induced via Submaximal Contractions Similarly Impairs Hand Tracking Accuracy in Young Adult Males and Females

We evaluated the effects of muscle fatigue on hand-tracking performance in young adults. Differences were quantified between wrist flexion and extension fatigability, and between males and females. Participants were evaluated on their ability to trace a pattern using a 3-degrees-of-freedom robotic manipulandum before (baseline) and after (0, 1, 2, 4, 6, 8, and 10 mins) a submaximal-intensity fatigue protocol performed to exhaustion that isolated the wrist flexors or extensors on separate days. Tracking tasks were performed at all time points, while maximal voluntary contractions (MVCs) were performed at baseline, and 2, 6-, and 10-mins post-task termination. We evaluated movement smoothness (jerk ratio, JR), shape reproduction (figural error, FE), and target tracking accuracy (tracking error, TE). MVC force was significantly lower in females (p < 0.05), lower than baseline for all timepoints after task termination (p < 0.05), with no muscle group-dependent differences. JR did not return to baseline until 10-mins post-task termination (most affected), while FE returned at 4-mins post-task termination, and TE at 1-min post-task termination. Males tracked the target with significantly lower JR (p < 0.05), less TE (p < 0.05), and less FE (p < 0.05) than females. No muscle group-dependent changes in hand-tracking performance were observed. Based on this work, hand tracking accuracy is similarly impaired following repetitive submaximal dynamic wrist flexion or extension. The differences between male and female fatigability was independent of the changes in our tracking metrics.
Correlation Between Plasma CircRNA-089763 and Postoperative Cognitive Dysfunction in Elderly Patients Undergoing Non-cardiac Surgery

In our previous experiment, we found that there were abnormal levels of circRNA-089763 in the plasma exosomes of patients with postoperative cognitive dysfunction (POCD) after cardiac surgery. Therefore, the aim of this study was to further investigate the relationship between plasma circRNA-089763 level and POCD in elderly patients after non-cardiac surgery. A prospective cohort study was conducted to select elderly patients undergoing elective non-cardiac surgery. A total of 72 patients were enrolled in this study, and cognitive functions were assessed 1 day before and 3 days after surgery by a series of neuropsychological measurements. Next, patients were divided into POCD and non-POCD (NPOCD) groups according to the Z score method. Blood was collected the day before and 3 days after surgery, and the plasma circRNA-089763 level was detected by quantitative real-time polymerase chain reaction (qRT-PCR). Then, the difference and correlation in plasma circRNA-089763 levels between the POCD and NPOCD groups were analyzed. On the third day after surgery, the incidence of POCD was 30.56%. The relative level of circRNA-089763 in the POCD group was 2.41 times higher than that in the NPOCD group (t = 4.711, p < 0.001), patients in POCD group had higher age (t = 5.971, p < 0.001), higher American Society of Anesthesiologists classification (χ2 = 14.726, p < 0.001), less years of education (t = 2.449, p = 0.017), more intraoperative blood loss (t = 3.196, p = 0.002), and higher visual analog scale (VAS) scores (t = 10.45, p < 0.001). The binary logistic regression analysis showed that the circRNA-089763 level, age, and intraoperative blood loss were independently associated with POCD (OR: 2.75, 95% CI: 1.261–5.999, p = 0.011; OR: 1.32, 95% CI: 1.114–1.565, p = 0.001; OR: 1.017, 95% CI: 1.004–1.03, p = 0.011). These results demonstrated that the circRNA-089763 plasma level was related to POCD after non-cardiac surgery in elderly patients.

Self‐reliant rovers for increased mission productivity

Achieving consistently high levels of productivity has been a challenge for Mars surface missions. While the rovers have made major discoveries and dramatically increased our understanding of Mars, they require a great deal of interaction from the operations teams, and achieving mission objectives can take longer than anticipated when productivity is paced by the ground teams' ability to react. We have conducted a project to explore technologies and techniques for creating self‐reliant rovers (SRR): rovers that are able to maintain high levels of productivity with reduced reliance on ground interactions. This paper describes the design of SRR and a prototype implementation that we deployed on a research rover. We evaluated the system by conducting a simulated campaign in which members of the Mars Science Laboratory (Curiosity rover) science team used our rover to explore a geographical region. The evaluation demonstrated the system's ability to maintain high levels of productivity with limited communication with operators.
Molecular Identification of Secreted Effector Genes Involved in African Fusarium oxysporum f.sp. elaeidis Strains Pathogenesis During Screening Nigerian Susceptible and Tolerant Oil Palm (Elaeis guineensis Jacq.) Genotypes

Fusarium wilt is caused by Fusarium oxysporum f. sp. elaeidis, and constitutes a severe threat to the oil palm industry in Africa. This study is aimed at surveying, identifying the secreted effector genes responsible for virulence during pathogenesis, and investigating the level of genetic diversity and cluster resolutions of alleles accountable for virulence in pathogenic strains of F. oxysporum f.sp. elaeidis from African countries. Fifty-eight fungal strains were isolated from acute and chronic Fusarium wilt diseased oil palms in Nigeria, Ghana and Cameroon. Morphological and sequencing analysis of the Internal Transcribed Spacer (ITS) region grouped all strains into nine dominant strains with a majority (41.37%) belonging to F. oxysporum, followed by F. solani (20.68%), F. equiseti (20.68%), F. verticilliodes (5.17%), F. proliferatum (3.44%), F. chlamydosporum (3.44%), F. nelsonii (1.72%), Fomes fomentarius, and Penicillium simplicissimum (1.72%). Disease incidence and severity showed varying levels of virulence with some Fusarium strains causing severe symptoms while others exhibited slight symptoms. ISSR evaluation disclosed a considerable level of genetic diversity among pathogenic F. oxysporum f.sp. elaeidis strains. Molecular characterization using defense gene primers revealed that the oil palm genotypes screened did not amplify defense genes. During pathogenesis, Fusarium strains produced GMC oxidoreductases, hypothetical proteins, FOIG 16629, FOXG 14258, and Pyranose dehydrogenase 3-like proteins using virulent effector gene primers. Polymerase Chain Reaction analysis using specific gene primers revealed that PRK02106, beta and BetA effector genes were secreted explicitly by F. oxysporum f.sp. elaeidis (4) and F. oxysporum f.sp. elaeidis (CRT) strains while screening tolerant oil palm genotypes. During screening susceptible oil palm genotypes, F. oxysporum f.sp. elaeidis (4) and F. oxysporum f.sp. elaeidis (CRT) strains produced FGGY_L-XK1, PRK10939, FGGY_N1, XylB1, XylB2, FGGY_L-XK2, XylB3, FGGY_N2, and XylB4 effector genes. Identifying these effector genes will provide the platform to study the basis of pathogenesis which will help breeders to modify breeding techniques for the improvement of oil palm genotypes in order to reduce oil palm loss in plantations and enhance food security.
Change of ATP content in Echinochloa crus-galli var. praticola seeds during imbibition and storage.

1. Echinochloa crus-galli var. praticola seeds were imbibed for 0, 6, 12, 24, 36, 48, 60 and 72 hours and then measured for their ATP content. ATP level increased very rapidly after seed imbibition for 6 hours, becoming almost constant after 36 hours. The highest ATP content was observed at 72 hours of imbibition.2. ATP content during the storage period of E. crus-galli var. praticola which had been harvested between 1972 and 1986 was examined and the relationship with viability sought. It was found that: 1) ATP content progressively decreased with increasing storage period over 3 years after harvest and reached an undetectable in seeds eleven years after harvest. 2) Only those seeds harvested in 1980 to 1986 germinated, with 1984 seeds showing the highest percentage. 3) A very close relationship was found between ATP content and germination rate, suggesting that the mechanisms responsible for ATP production and consumption function with 48 hours of imbibition.

Quasi-Passive Indoor Optical Wireless Communication Systems

Optical wireless communications (OWCs) have been widely studied to provide high-speed wireless services in indoor environments, and the combination of beam steering with localization has been explored to extend the coverage area and to provide user mobility. However, beam steering typically consumes continuous power, even when the user is stationary. In this paper, we propose and demonstrate a quasi-passive indoor OWC system with zero power consumption when the user is stationary or quasi-stationary. It also supports the generation of multiple signal beams for multi-user access. 10 Gb/s transmission is demonstrated and users at different locations are served simultaneously. Experimental results show that no power penalty is observed compared to traditional systems consuming continuous power. The proposed quasi-passive system provides a multi-user access and low-power consumption solution for indoor applications.
An Analysis of the Impact of XBRL Filings Towards Information Asymmetry in Indonesia

This study aims to examine whether XBRL filings by Indonesian companies could reduce information asymmetry, measured by the bid-ask spread. Among others, XBRL filings is expected to result in higher accuracy, validity and transparency of data, cost efficiency, as well as lower information asymmetry in the capital market. A total of 6-year period, which consists of pre-XBRL period (2012-2014) and post-XBRL period (2016-2018) from 65 companies were observed. Control variables included in this study are firm size, stock price and trading volume. The data analysis method used in this study is multiple regression analysis. Contrary to the hypothesis proposed, the result of multiple regression analysis shows no evidence that XBRL adoption reduces information asymmetry in Indonesia. This could be due to the fact that Indonesia is still in early stage of XBRL reporting and considered as early adopters. It might take several years before stakeholders could benefit from XBRL filings in corporate financial reporting.
