Inductive magnetic energy harvesting: modeling, power conversion and control.

This thesis first reviews the challenges and limitations of the existing approaches designed for inductive magnetic energy harvesting systems. An equivalent circuit model of magnetic energy harvester is developed, which takes into account the nonlinearity of the magnetic reluctance and flux. Then, using the models, a family of low threshold capacitive rectifier topologies and a center tapped boost-derived AC-DC converter are derived for better convert the AC harvesting power to DC voltage. Both of the approaches avoid using the conventional two stage structure and increases the efficiency and system output power. Two new impedance matching control algorithms for bridgeless AC-DC power conversion of magnetic harvester are presented: a Phase/RMS maximum power point tracking (MPPT) method, which controls the phase and RMS value of the converter input current without voltage reference, and a Quasi-MPPT method simplified from Phase/RMS MPPT. Experimental results are presented to validated the proposed modeling, power conversion and control approaches. Comparison with previous work shows that the proposed approaches achieve higher output power for the magnetic energy harvesting system.
Rough bibliographical notes on intrinsic images, equivariance and relighting

Direct evaluation methods include: WHDR [12]; scores on the images of [43] (but there are very few images in unrealistic illumination [6]); and scores on SINTEL frames (from [23]), as in [25] (but this rendered data is quite unlike real images as in [58], section 2). Multiimage data Emerging papers The WHDR evaluation framework was put in place by [12], who constructed a dataset (Intrinsic Images in the Wild or IIW) consisting of human judgements which compare the absolute lightness at pairs of points in real images. Each pair is labelled with one of three cases (first lighter; second lighter; indistinguishable) and a weight, which captures the certainty of labellers. One evaluates by computing a weighted comparison of algorithm predictions with human predictions; the comparison is known as the weighted human disagreement ratio (WHDR). Predictions were originally by testing ratios of estimated albedo against a standard threshold [12]. Other authors test against a threshold chosen using validation data (eg. rescaling of Retinex in [70]), or test differences in estimated log-albedo (eg [70]). The choice of predictor is significant. Differences in logalbedo are scale invariant, but this predictor may perform poorly over the full range of albedos. Two quite similar dark albedos will have the same difference in logs as two quite different light albedos. Differences in albedo are not scale invariant, and this means that the scale on which the algorithm reports albedo and the test thresholds are fungible. Some authors fix threshold, and learn scale; others fix scale and choose threshold using validation data.
The Relationship Between Despotic Leadership and Employee Outcomes: An Empirical Study from Pakistan

Through emotional exhaustion, this study empirically tests followers’ behavioral responses to autocratic leaders. The current research focuses on effects caused by despotic leadership on followers’ emotional exhaustion, which leads to employee outcomes such as interpersonal deviances and indirect aggression. The association between despotic leadership and results (employee interpersonal deviance and indirect violence) is investigated in this study. In this study, emotional exhaustion is used as a mediator. Furthermore, negative affectivity is used as a moderator between despotic leadership and emotional exhaustion. A time-lagged framework is employed with a sample of 255 respondents. Age, qualification, marital status, gender, grade, type of organization, department, and job experience are among the eight demographical questions in this study. After evaluating the data for normality, correlation analysis was performed, followed by moderation and mediation analysis. The current study explores the link between despotic leadership and emotional exhaustion among followers, arguing that a despotic leader will leave followers exhausted at work. Emotional exhaustion was also linked to interpersonal deviances, such as indirect aggression, in a significant and positive way. Employee outcomes, such as interpersonal deviances and indirect aggressiveness through emotional exhaustion, will be influenced by a despotic leader, according to the findings.
DIFNet: Boosting Visual Information Flow for Image Captioning

Current Image Captioning (IC) methods predict textual words sequentially based on the input visual information from the visual feature extractor and the partially generated sentence information. However, for most cases, the partially generated sentence may dominate the target word prediction due to the insufficiency of visual information, making the generated descriptions irrelevant to the content of the given image. In this paper, we propose a Dual Information Flow Network (DIFNet11Source code is available at: https://github.com/mrwu-mac/DIFNet) to address this issue, which takes segmentation feature as another visual information source to enhance the contribution of visual information for prediction. To maximize the use of two information flows, we also propose an effective feature fusion module termed Iterative Independent Layer Normalization (IILN) which can condense the most relevant inputs while retraining modality-specific information in each flow. Experiments show that our method is able to enhance the dependence of prediction on visual information, making word prediction more focused on the visual content, and thus achieves new state-of-the-art performance on the MSCOCO dataset, e.g., 136.2 CIDEr on COCO Karpathy test split.
Effects of Information Technology Competence on Business Performance: Empirical Evidence from Omnichannel Retailers in Vietnam

Nowadays, omnichannel is a new kind of e-commerce channel. Many retailers invest in this channel to maximize customers’ benefits as well as increase competitive advantage and business performance. To operate this channel effectively, the role of IT competence is very important. With the flexibility and integration of IT competence in omnichannel, retailers can optimize service quality and bring customer benefits that are outstanding in comparison with the traditional channel. Because of this significance, this research was carried out to evaluate the effects of IT competence on the business performance of retailers in Vietnam’s omnichannel environment through the mediating role of customer value creation and competitive advantage. A quantitative research method is used through a survey with 200 managers working in retail companies operating omnichannel in Vietnam. After collecting data, PLS-SEM software is used to analyze the relationship among these above factors in omnichannel. The results prove that there are positive effects of IT competence on other elements in the research model. All direct and indirect effects are valuable when bootstrapping. Based on the results, some managerial implications are given to managers of retail companies using omnichannel to improve customer values and increase competitive advantage and business performance in the Vietnam context.
Threats to Adversarial Training for IDSs and Mitigation

: Intrusion Detection Systems (IDS) are essential tools to protect network security from malicious trafﬁc. IDS have recently made signiﬁcant advancements in their detection capabilities through deep learning algorithms compared to conventional approaches. However, these algorithms are susceptible to new types of adversarial evasion attacks. Deep learning-based IDS, in particular, are vulnerable to adversarial attacks based on Generative Adversarial Networks (GAN). First, this paper identiﬁes the main threats to the robustness of IDS against adversarial sample attacks that aim at evading IDS detection by focusing on potential weaknesses in the struc-ture and content of the dataset rather than on its representativeness. In addition, we propose an approach to improve the performance of adversarial training by driving it to focus on the best evasion candidates samples in the dataset. We ﬁnd that GAN adversarial attack evasion capabilities are signiﬁcantly reduced when our method is used to strengthen the IDS.
Influences of multicenter bonding and interstitial elements on pseudo-twinned γ-TiAl crystal

The electronic properties of pseudo-twin boundary in γ-TiAl intermetallic and the influence of interstitial alloying atoms on them are investigated through ab initio calculation. Similar to true twin boundary, there exist three-central bonds at the pseudo-twin boundary, which are discussed by local energy scheme combined with electron localization function and quantum theory of atoms in molecules schemes. The effect of interstitial atoms C, N, H and O on slipping energy is separated into the contributions of affinity of interstitial atoms to host atoms and the multi-center bonds. In shearing process of pseudo-twin configuration, a local true twin boundary is formed in the neighbor layer of the initial pseudo-twin boundary, resulting in a plateau formed in stacking fault energy curve.
Interrogation on the Cellular Nano-Interface and Biosafety of Repeated Nano-Electroporation by Nanostraw System

Cell perforation is a critical step for intracellular drug delivery and real-time biosensing of intracellular signals. In recent years, the nanostraws system has been developed to achieve intracellular drug delivery with minimal invasiveness to the cells. Repeated cell perforation via nano-system could allow delivery of multiple drugs into cells for cell editing, but the biosafety is rarely explored. In this work, a nanostraw-mediated nano-electroporation system was developed, which allowed repeated perforation of the same set of cells in a minimally invasive manner, while the biosafety aspect of this system was investigated. Highly controllable fabrication of Al2O3 nanostraw arrays based on a porous polyethylene terephthalate (PET) membrane was integrated with a microfluidic device to construct the nanostraw-electroporation system. The pulse conditions and intervals of nano-electroporation were systematically optimized to achieve efficient cells perforation and maintain the viability of the cells. The cells proliferation, the early apoptosis activities after nanostraw-electroporation and the changes of gene functions and gene pathways of cells after repeated nano-electroporation were comprehensively analyzed. These results revealed that the repeated nanostraw-electroporation did not induce obvious negative effects on the cells. This work demonstrates the feasibility of repeated nano-electroporation on cells and provides a promising strategy for future biomedical applications.
Effects of Whole-Body Vibration Training with Different Body Positions and Amplitudes on Lower Limb Muscle Activity in Middle-Aged and Older Women

Purpose The present study was designed to investigate the electromyographic (EMG) response in leg muscles to whole-body vibration while using different body positions and vibration amplitudes. Methods: An experimental study with repeated measures design involved a group of community-dwelling middle-aged and older women (n = 15; mean age=60.8 ± 4.18 years). Muscle activity of the gluteus maximus (GM), rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), and gastrocnemius (GS) was measured by surface electromyography, which participants were performing three different body positions during three WBV amplitudes. The body positions included static semi-squat, static semi-squat with elastic band loading, and dynamic semi-squat. Vibration stimuli tested were 0 mm, 2 mm, and 4 mm amplitude and 30 Hz frequencies. And the maximum accelerations produced by vibration stimuli with amplitudes of 2 mm and 4 mm are approximately 1.83 g and 3.17 g. Results: Significantly greater muscle activity was recorded in VL, BF, and GS. When WBV was applied to training, compared with the same training without WBV (P < .05). There were significant main effects of body positions on EMGrms for the GM, RF, and VM (P < .05). Compared to static semi-squat, static semi-squat with elastic band significantly increased the EMGrms of GM, and dynamic semi-squat significantly increased the EMGrms of GM, RF and VM (P < .05). And there were significant main effects of amplitudes on EMGrms for the GM, RF, and VM (P < .05). The EMGrms of the VL, BF, and GS at 4 mm were significantly higher than 0 mm, and the EMGrms of the VL and BF at 4 mm were significantly higher than 2 mm. There was no significant body interaction between body positions and amplitudes (P > .05). Conclusions: The EMG amplitudes of most leg muscles tested were significantly greater during WBV exposure than in the no-WBV condition. The dynamic semi-squat 4 mm whole-body vibration training is recommended for middle-aged and older women to improve lower limb muscle strength and function.
Survey on the Past Decade of Technology in Animal Enrichment: A Scoping Review

Simple Summary Enrichment is important for supporting the well-being of captive animals. Enrichment increase animal quality of life through encouraging natural behaviours. As enrichment is shifting to a more centered role in animal care, technology is becoming increasingly accessible and is becoming embedded in animal enrichment in creative ways. This review explores the trends in technology usage in animal enrichment studies. Through pulling the past decade of technology enrichment work together, we discuss gaps such as needing to include a larger variety of species (extending passed mammals), ensuring enrichment designs focus primarily on the senses an animal uses to interact with the world rather than human senses, and encouraging similar study designs across animal contexts to allow for streamlined comparisons. Abstract Environmental enrichment is adding complexity to an environment that has a positive impact on a captive animal as a necessity of care. Computing technology is being rapidly weaved throughout the space in both enrichment devices as well as evaluating enrichment outcomes. In this article, we present a scoping review of 102 captive animal enrichment studies and propose a contextual lens for exploring current practices. We discuss the importance of directed growth in species inclusion, transitioning beyond anthro-centric designs, and utilizing shared methodologies.
Photonic spin Hall effect: fundamentals and emergent applications

The photonic spin Hall effect (SHE) refers to the transverse spin separation of photons with opposite spin angular momentum, after the beam passes through an optical interface or inhomogeneous medium, manifested as the spin-depend-ent splitting. It can be considered as an analogue of the SHE in electronic systems: the light’s right-circularly polarized and left-circularly polarized components play the role of the spin-up and spin-down electrons, and the refractive index gradient replaces the electronic potential gradient. Remarkably, the photonic SHE originates from the spin-orbit interaction of the photons and is mainly attributed to two different geometric phases, i.e., the spin-redirection Rytov-Vlasimirskii-Berry in momentum space and the Pancharatnam-Berry phase in Stokes parameter space. The unique properties of the photonic SHE and its powerful ability to manipulate the photon spin, gradually, make it a useful tool in precision metrology, analog optical computing and quantum imaging, etc. In this review, we provide a brief framework to describe the fundamentals and advances of photonic SHE, and give an overview on the emergent applications of this phenomenon in different scenes.
Comparison-based MPC in Star Topology

: With the large amount of data generated nowadays, analysis of this data has become eminent. Since a vast amount of this data is private, it is also important that the analysis is done in a secure manner. Comparison-based functions are commonly used in data analysis. These functions use the comparison operation as the basis. Secure computation of such functions have been discussed for median by Aggarwal et al. (EUROCRYPT’04) and for convex hull by Shelat and Venkitasubramaniam (ASIACRYPT’15). In this paper, we present a generic protocol for the secure computation of comparison-based functions. In order to scale to a large number of participants, we propose this protocol in a star topology with an aim to reduce the communication complexity. We also present a protocol for one specific comparison-based function, the k th ranked element. The construction of one of our protocols leaks some intermediate values but does not reveal information about an individual party’s inputs. We demonstrate that our protocol offers better performance than the protocol for k th ranked element by Tueno et. al. (FC’20) by providing an implementation.
Aircraft Technology Assessment Using Fleet-Level Metrics

Commercial aviation is expected to grow by 3 to 5% annually within the upcoming two decades. Its adverse impact on the environment will thus aggravate, if no countermeasures are taken. This thesis evaluates the fuel saving and emissions reduction potential of today’s most recent aircraft types and technologies by developing a methodology that quantifies their effects in view of the dynamically evolving global air transport fleet. It is found that the considered aircraft types may lead to a global efficiency gain of up to 0.8% annually until 2050. Hence, further measures are needed for a sustainable development of aviation.
Organizational Identification Moderates the Relationship Between the Job Satisfaction and Job Performance- Evidence in University Lecturers in Vietnam

Although the number of universities in Vietnam has expanded significantly in recent decades, the quality gap in the country's higher education has recently received much attention. Much qualitative research determined why more and more university graduates are out of work and university lecturers move to other jobs, which are the causes affecting job satisfaction, and work efficiency. However, there is still a lack of quantitative research to examine this issue. This study adds to the findings of previous studies. It enriches the research literature by examining Organizational definition as a variable detailing the relationship between job satisfaction and job performance among Vietnamese university lecturers. We conducted a cross-sectional survey (n = 200). Multiple linear regression and moderator regression analysis tested the proposed hypotheses. Research results show a positive and significant relationship between organizational identity, job satisfaction, and job performance of Vietnamese university lecturers. In particular, organizational identity functions as a moderating variable of the relationship between job satisfaction and job performance.
Self-Repairing Herpesvirus Saimiri Deletion Variants

Herpesvirus saimiri (HVS) is discussed as a possible vector in gene therapy. In order to create a self-repairing HVS vector, the F plasmid vector moiety of the bacterial artificial chromosome (BAC) was transposed via Red recombination into the virus genes ORF22 or ORF29b, both important for virus replication. Repetitive sequences were additionally inserted, allowing the removal of the F-derived sequences from the viral DNA genome upon reconstitution in permissive epithelial cells. Moreover, these self-repair-enabled BACs were used to generate deletion variants of the transforming strain C488 in order to minimalize the virus genome. Using the en passant mutagenesis with two subsequent homologous recombination steps, the BAC was seamlessly manipulated. To ensure the replication capacity in permissive monkey cells, replication kinetics for all generated virus variants were documented. HVS variants with increased insert capacity reached the self-repair within two to three passages in permissive epithelial cells. The seamless deletion of ORFs 3/21, 12–14, 16 or 71 did not abolish replication competence. Apoptosis induction did not seem to be altered in human T cells transformed with deletion variants lacking ORF16 or ORF71. These virus variants form an important step towards creating a potential minimal virus vector for gene therapy, for example, in human T cells.
Effect of Acupotomy Combined with Electroacupuncture Therapy on Finger Mobility and Pain Relief in Patients with Carpal Tunnel Syndrome

Objective To explore the effect of acupotomy in combination with electroacupuncture therapy on the finger mobility and pain relief in patients who had carpal tunnel syndrome (CTS). Methods The clinical data of 60 CTS patients in our hospital from November 2020 to November 2021 received retrospective analysis. With 30 cases in each group, they were randomly divided into the treatment group and the control group. The control group underwent hot compress, oral medication, and local injection during hospitalization, while the treatment group received acupotomy and electroacupuncture therapy on top of the above treatments, and the clinical effects, finger mobility, and pain relief were compared between both groups. Results The clinical indexes in the treatment group after treatment were remarkably better than those in the control group (P < 0.05), with the remarkably higher number of cured cases in the treatment group (P < 0.05). After treatment, the treatment group had remarkably higher mean total active motion (TAM) and score of the 36-item short form (SF-36) health survey and a remarkably lower mean score of visual analog scale (VAS) than those in the control group (P < 0.001). Conclusion The quality of life and finger mobility of CTS sufferers can be improved with acupotomy in conjunction with electroacupuncture therapy. In-depth research will help build better procedures for these patients because this approach lessens the discomfort and shortens the symptom duration in CTS sufferers.
Improving 3-D NAND SSD Read Performance by Parallelizing Read-Retry

With the bit density improvement and the 3-D flash techniques, modern NAND flash-memory-based solid-state disks (SSDs) dramatically increase the flash storage capacity. However, in high-density SSDs, the long read latency overheads due to massive read-retry steps have become a serious performance concern to develop flash memory in storage devices. In this article, we proposed a parallel read-retry scheme (PaRR) to utilize the read-retry characteristics among flash memory cells. Specifically, when reading the multiple data pages simultaneously, PaRR reduces the read-response time by parallelizing read-retry operations. PaRR reduces the number of read-retry operations by parallelizing read-retry steps with the different aggressive read reference voltages if simultaneously reading the data pages that exhibit virtually equivalent reliability characteristic. Our evaluation shows that PaRR improves the I/O performance by 33.77% on average compared with the state-of-the-art scheme.
