Soft Switching for Strongly Coupled Wireless Power Transfer System With 90° Dual-Side Phase Shift

To increase the power density of a wireless power transfer (WPT) system, the coupling of coils can be strong. However, in a strongly coupled series–series WPT system with a diode rectifier, currents can be distorted and discontinuous, and first harmonic approximation is no longer valid. The inverter is likely to work in hard switching, leading to extra noise, decreased efficiency, and a potential hazard for a safe operation. Through time-domain analysis, this article reveals that with a dual-side 90° phase shift, the hard switching of the inverter can be avoided, the power level can be enhanced, and the discontinuous conduction mode can be avoided to eliminate noises. The factors impacting the soft switching operations of the inverter and the rectifier are analyzed. To achieve 90° dual-side phase shift, the conventional approach of using the receiver voltage/current, which can be distorted and discontinuous in strongly coupled WPT systems, for phase synchronization is no longer suitable. A new set of coils, namely driving coils, is used for phase synchronization so that dual-side phase shift can be implemented independent from power transfer. Experimental results have validated the effectiveness of the analysis.
Conflicting messages of electoral protest: The role of systemic and elite discontent in the Italian 2016 constitutional referendum

The vote NO (a defeat for the proponents) of the 2016 Italian referendum has been broadly attributed to a wave of protest politics sweeping Western democracies. Given that the government of Matteo Renzi proposed and supported the referendum, the resulting vote against government interests raises a crucial theoretical question: to what extent does the referendum vote reflect the characteristics of a protest vote? To disentangle the meaning and impact of protest, we distinguish two dimensions: the ‘system discontent’ and the ‘elite discontent’, referring to both general and focalized images: general sentiments towards the representational aspects of political institutions as compared to focused sentiments towards government performances. The circumstances surrounding the referendum provide a crucial test for whether these two forms of protest can be at odds with one another. We expect and find that elite discontented voters tend to reject this referendum. Vice versa, system discontent increased support for the referendum, as it would reform political institutions to which voters had negative sentiments. Findings suggest that analyses of political psychology and behaviour identify the conceptual foundations for protest and ask whether forms of protest work in parallel or at odds. Protest attitudes and their effects should be thought of as multidimensional.
Detection of specific noncovalent protein-fullerenols complexes by matrix-assisted laser desorption ionization mass spectrometry

Matrix-assisted laser desorption ionization (MALDI) mass spectrometry is difficult for the characterization of noncovalent complexes hitherto because of the limitations in acidic matrix, sample preparation, laser-induced polymerization and adduct formation with matrix. Under our experimental conditions, sinapinic acid is used as a matrix, the specific noncovalent interactions of protein with fullerenols were observed by MALDI mass spectrometry. Some mass spectrometric features, such as mass shifts, broad adduct peaks and stoichiometries, showed that the specific non-covalent complexes between protein and fullerenols have been formed at a ratio of 1 : 4 for hemoglobin-fullerenols or 1 : 1 for myoglobin-fullerenols. The results implied that fullereneols could be used to protect partly hemoglobin from decomposition in acidic media, and therefore, it is possible to realize the molecular weight determination of a quaternary protein by MALDI mass spectrometry via the addition of specific organic compound in the matrix.
Pseudocapacitance-tuned high-rate and long-term cyclability of NiCo2S4 hexagonal nanosheets prepared by vapor transformation for lithium storage

The high conductivity of bimetallic thiospinel NiCo2S4 endows energy storage devices with very fascinating performance. However, the unsatisfactory rate capability and long-term cyclability of this material series significantly limit their large-scale practical applications such as in electric vehicles and hybrid electric vehicles. Herein, we successfully synthesized NiCo2S4 hexagonal nanosheets with a large lateral dimension of ∼1.35 μm and a thickness of ∼30 nm through a vapor transformation method. The dynamic transformation process of the NiCo2S4 polycrystalline nanosheets from NiCo-hydroxide has been revealed in detail. Originating from their two-dimensional thin-sheet structure with a high aspect ratio, the induced extrinsic capacitive contribution as high as 91% makes them an ideal candidate for high-capacity and high-rate lithium-ion anodes. The NiCo2S4 nanosheets deliver a reversible capacity of 607 mA h g−1 upon 800 cycles at a current density of 2 A g−1. This outstanding long cycle performance sheds light on the structural design of electrode materials for high-rate lithium-ion batteries.

Three new Entoloma species of the Cyanula clade from (sub)alpine habitats in Northern Norway and Sweden

Three Entoloma species belonging to the Cyanula clade from (middle-) northern boreal and alpine areas are described as new to science. Entoloma montanum, E. nordlandicum, and E. septentrionale, recorded from the Holmvassdalen area at Grane, North- ern Norway while E. montanum shows a wide distribution in Northern Scandinavia and the Caucasus. Entoloma nordlandicum, however, has recently been recorded also from the Netherlands. The three species are phylogenetically well defined based on analysis of the nrDNA ITS region and they are distant from their closest relatives. Morphological descriptions of each species are given, as well as their ecology, distribution and relationships towards similar species are discussed.
Homelessness prevention and determinants of housing among first-time and recurrent emergency shelter users in Canada

Abstract Primary and secondary prevention initiatives stop people from becoming homeless and help them exit quickly when they do. This study uses administrative data from emergency shelters in Canada from 2010–2016 to compare homelessness pathways and housing outcomes between first-time and recurrent shelter users. It uses a multinomial logit model to identify factors that influence the likelihood of exiting into housing following a shelter stay. The findings demonstrate that first-time users are over two times more likely to exit into newly acquired housing than recurrent users, and that the pathways into and out of homelessness vary significantly between the two groups. The findings suggest that the composition of existing prevention strategies do not sufficiently meet the needs of first-time users experiencing financial and substance use challenges. For recurrent users, federal policies that promote Housing First initiatives increase exits into housing. However, duration of previous homelessness negatively influences housing outcomes, reinforcing the need for early intervention prevention initiatives.
A questionnaire based survey to assess knowledge, attitude and practice regarding nicotine replacement therapy (NRT) among dental students in Navi Mumbai

The purpose of this study was to assess the knowledge, attitude and practice among the dental students including interns and postgraduate students towards Nicotine Replacement Therapy(NRT). This is a cross sectional survey done among 300 randomly chosen dental students from dental colleges in Navi Mumbai by distributing a self-prepared questionnaire about the awareness and use on NRT. Later, descriptive analysis was done on the data collected. Eighty four percent of the dental students were aware of NRT. Significant awareness was seen among the dental students, but only 28% of the dental students had the practice of always prescribing patients with NRT, 40% of the dental students prescribed NRT sometimes and the remaining 32% never prescribed NRT for tobacco cessation. The awareness on NRT and the practice of prescribing patients with NRT for tobacco cessation was not proportionate.
Integrated analysis of iron metabolic-related genes in hepatocellular carcinoma

Background Iron is a nutrient essential for hemoglobin synthesis, DNA synthesis, and energy metabolism in all mammals. Iron metabolic involved in numerous types of cancers including hepatocellular cancer. In this study, we aim to identify prognostic model that based on iron metabolic-related genes that could effectively predict the prognosis for HCC patients. Methods The RNA microarray and clinical data of HCC patients that obtained from The Cancer Genome Atlas (TCGA) database. We identify the clusters of HCC patients with different clinical outcome performed by consensus clustering analysis. Four iron metabolic-related genes (FLVCR1, FTL, HIF1A, HMOX1) were screen for prognostic model by performed the Cox regression analysis. The efficacy of prognostic model was validated by the International Cancer Genome Consortium (ICGC) database. Meantime, the expressions value of FLVCR1, FTL, HIF1A, HMOX1 was performed using Oncomine database, the Human Protein Atlas and Kaplan Meier-plotter. Result The patients with low-risk score have better prognosis than high risk score both in TCGA cohort and ICGC cohort. The prognostic model showed well performance for predicting the prognosis of HCC patients than other clinicopathological parameters by OS-related ROC curves. Conclusion Our survival models that based on Iron metabolic can be independent risk factors for hepatocellular carcinoma patients.
Expression and distribution of neuroglobin and hypoxia-inducible factor-1α in the diencephalon of young yaks

The diencephalon is a region of the vertebrate neural tube that gives rise to posterior forebrain structures and contains, among others, the epithalamus, thalamus, and hypothalamus. High-altitude is a component of the physical environment to which animals adapt (10). High-altitude environments present many physiological challenges for mammals because the increasing altitude is characterized by decreasing oxygen availability in the environment without major changes in tissue requirements. In 2000, Burmester et al. (1) observed that Ngb is expressed in the vertebrate nervous system. Zhao et al. (21) reported that Ngb is highly expressed in the brain of mice with traumatic brain injury, whereas in humans Ngb is significantly expressed in the hypothalamus, amygdala, and pontine tegmental nuclei (14). In the hypothalamus and cerebrum of sheep, Ngb shows a lower expression (8). Oxygen (O2) is vital for respiration, which is a process that transfers energy from glucose to cells. To adapt to this condition, evolutionarily conserved responses must be engaged. In mammals and other non-vertebrate species, the primary transcriptional factor that responds to hypoxic stress is mediated by a dimeric protein called the hypoxiainducible factor (Hif-1α). Hif-1α is an important transcription factor that regulates oxygen consumption and morphological changes in response to varying oxygen concentrations. Frank et al. (9) reported that Hif-1α targets genes in the adult rat brain and promotes cell survival in hypoxic tissues. A study conducted by Joana et al. ascertained that Hif-1α expression in the hypothalamus regulates cellular responses to inflam* This research project was funded by the National Natural Science Foundation of China (Grant No. 31760305).

Housing prices and speculation dynamics: a study of Auckland housing market

ABSTRACT Many housing markets across the globe have experienced upward trends in real estate prices during the past two decades. The dynamics between housing prices and speculation have been analysed by existing housing literature, but this study has a few features that may deepen the understanding of this topic. This research uses transaction-level data, focuses on only investor-purchase records, distinguishes leveraged transactions from unleveraged ones and adopts a new proxy for property speculation. Furthermore, the price elasticity of housing supply has been examined as the price responsiveness is important for understanding the topic in a supply-constrained market. We build a stock adjustment model to estimate the elasticity and a vector error-correction model to conduct Granger causality tests, impulse response analyses and a variance decomposition analysis. The findings uncover a feedback loop in a market with inelastic housing supply: investors’ speculative behaviour lifts Auckland housing prices which in turn spur further housing speculation.
Beneficial Effects of Liposome Containing Arthrocen (ROCEN)) on Atopic Dermatitis in Mice

Objective: Atopic dermatitis (AD) is a chronic inflammatory skin disease caused mainly by the immune stimulus. The current study aimed to investigate the effects of liposome containing arthrocen (ROCEN) and its comparison with betamethasone (Beta) on mice subjected to AD. Methods: First of all, the risk assessment of ROCEN sensitization was done, then mice were subjected to oxazolone (Oxa) for chronic AD induction and treatment. Scratching and wiping behaviors related to dermatitis were evaluated in animals treated topically with ROCEN. The histological and immunohistochemistry analysis of interleukin-8 (IL-8) and tumor necrosis factor-α (TNF-α) were conducted to the dorsal skin of treated rats. Results: The results showed that cutaneous administration of ROCEN on sensitized mice for 5 weeks, alleviated significantly scratching and wiping symptoms, erythema, scaling, and edema in animals’ skin. Moreover, histological indices showed that ROCEN reduced effectively leucocyte infiltration and improved skin healing parameters in AD mice. Immunohistochemically markers of IL-8 and TNF-α were hindered significantly by ROCEN in dermal tissues of mice. Conclusion: ROCEN potentiated alleviation of the AD symptoms rather than betamethasone drug in an experimental model.
Survival Benefits of Outpatient Cardiac Rehabilitation after Acute Myocardial Infarction: Propensity Analysis Using Japanese Administrative Database

Survival benefit of outpatient cardiac rehabilitation (CR) after acute myocardial infarction (AMI) has recently been contested under the current real-world clinical practice. We investi‐ gated whether outpatient CR was associated with lower mortality and morbidity risks among Japanese AMI patients. We analyzed patients who were admitted for AMI and received both percutaneous coronary intervention and inpatient CR from January 2011 to December 2014, using a nationwide administrative database in Japan (final date of follow-up: July 31, 2016). We compared patients who received outpatient CR and who did not, and the primary outcome was a com‐ posite of all-cause death and recurrence of AMI after the landmark time-point of day 180 after discharge. We applied Cox proportional hazards model to estimate outcomes, and propensity-score matching was applied to adjust for baseline imbalances. [0.87, 2.27] years), 730 (12.9%) participated in outpatient CR at least once within 180 days of discharge. Of 1,458 propensity-score matched patients, outpatient CR participation was associated with lower but statistically non-significant risks among the pri‐ mary outcome (1.38 vs. 2.12 per 100 patient-years; HR = 0.71; 95%CI, 0.32 to 1.61). Among Japanese patients who admitted for AMI and received both percutaneous coronary intervention and inpatient CR, outpatient CR was underutilized, and associated with a statistically non-significant mortality and morbidity benefits. Further study is necessary to reaffirm the real-world effectiveness of outpatient CR under the current real-world clinical practice.
Numerical Study of Scramjet Combustor with Tandem Dual Cavity for Nonreactive Jets

In the past decades flame out is a major phenomenon that paves way for high fuel consumption in scramjet combustion. For enhancing mixing and flame holding characteristics, different types of cavities are introduced in a scramjet combustion chamber which can hold air for a bit and acts like an atomizer. For increasing combustion efficiency and burnout ratios recirculation is maintained by using cavity and ramp angle techniques. In this paper numerical analysis has been carried out for two dimensional non-reacting flows in the combustor of scramjet engine with tandem dual cavity that creates high turbulent kinetic energy for ensuring combustion instability. This work is an enlightened approach for predicting the flow phenomenon that induces re-circulations after implementing various tandem dual cavities with varying length to diameter ratio and ramp angle. These in turn overcome low mixing rates due to compressibility effects at high convective Mach number.
Critical Role of Preferential Flow in Field‐Scale Pathogen Transport and Retention

A stochastic stream tube model was extended to simulate field‐scale pathogen transport and fate. Single‐ or dual‐permeability versions of the model were developed that included filtration theory. Pathogen transport and fate are highly dependent on the field‐scale velocity distribution. Physical nonequilibrium effects are coupled with retention, the velocity PDF, and exchange.
