A nonlinear control method of dynamic voltage restorers

Power quality and availability are becoming important issues for critical and sensitive loads. UPS is a complete solution for power quality problems, but high capital and running cost makes it an expensive solution. A series dynamic voltage restorer (DVR) provides load voltage support with a power rating equal to only a fraction of the load. At present, most of DVRs use feed-forward control because of the compensation response time requirement, this kind of control may introduce steady state error and on-site calibration problems. Although closed-loop PI regulation could not meet the dynamic response requirement, this paper demonstrates that a closed-loop nonlinear state variable control algorithm is a viable industrial solution. Practical issues, such as fault type analysis and controller design method, are included in the paper. The dynamic performance is analyzed and verified through simulation and experimental tests on a 2 kVA prototype.
Study on Spatial-Temporal Change of Urban Green Space in Yangtze River Economic Belt and Its Driving Mechanism

Urban green space plays an important role in beautifying the environment, improving the quality of life of residents, and promoting sustainable urban development. Rapid urbanization has led to great changes in the spatial structure and layout of urban green space. It is urgent to put forward the sustainable development strategy of green space through the research on the change of urban green space. Based on the geographical spatial differences of urban green space and integrating the factors of economy, society, industry, land use, and the environment, we constructed a research framework of “space-supply-demand” integration of urban green space by GI and geodetector methods, and we conducted an empirical study on the spatial–temporal changes of urban green space and its driving mechanism in prefecture-level cities along the Yangtze River Economic Belt in China. First, the urban green space along the Yangtze River Economic Belt is concentrated in spatial distribution, while uneven development appears in urban greening among the zones. Second, the influence of different factors on urban green space change varies greatly and can be divided into three types: key factors, important factors, and auxiliary factors. The driving mechanism of the spatial distribution of urban green space supply and demand is quite different, but urban population and commercial service facilities land are their key influence factors, having a comprehensive influence on the spatial–temporal changes of urban green space. Third, the factors are classified into three categories of high, medium, and low levels according to the mean of interacting forces; in particular, the factors of per capita GDP, utility land, industrial smoke (dust) emissions, and other factors have a very strong interactive effect with other factors. Fourth, according to the spatial distribution characteristics of urban green space and its driving mechanism, this paper puts forward planning and policy suggestions, providing reference for other areas to deal with the green space change.
Tightly coupled inhibitory and excitatory functional networks in the developing primary visual cortex

Intracortical inhibition plays a critical role in shaping activity patterns in the mature cortex. However, little is known about the structure of inhibition in early development prior to the onset of sensory experience, a time when spontaneous activity exhibits long-range correlations predictive of mature functional networks. Here, using calcium imaging of GABAergic neurons in the ferret visual cortex, we show that spontaneous activity in inhibitory neurons is already highly organized into distributed modular networks before visual experience. Inhibitory neurons exhibit spatially modular activity with long-range correlations and precise local organization that is in quantitative agreement with excitatory networks. Furthermore, excitatory and inhibitory networks are strongly co-aligned at both millimeter and cellular scales. These results demonstrate a remarkable degree of organization in inhibitory networks early in the developing cortex, providing support for computational models of self-organizing networks and suggesting a mechanism for the emergence of distributed functional networks during development.
Healthy diet, depression and quality of life: A narrative review of biological mechanisms and primary prevention opportunities

Unipolar depressive disorder (UDD) affects more than 264 million people worldwide and was projected well before the severe acute respiratory syndrome coronavirus 2 pandemic to be the leading cause of disability-adjusted life years lost in 2030. It is imperative for leading economies to implement preventive strategies targeted towards UDD, given consistent policies are currently lacking. Recently established similarities between the aetiological hypotheses of depression and cardiometabolic diseases are shifting paradigms within this field. It is believed that dietary practices could potentially reduce the incidence of depression; similar to their effects on metabolism. Thus, the aim of this review was to compile current evidence on healthy dietary patterns as suitable contributors towards primary prevention strategies against UDD. Most of the well-known biological mechanisms behind depression have been positively associated with healthful diets and dietary patterns to varying degrees. Interestingly, a common factor of UDD is the production and overall effects of inflammatory cytokines, such as interleukin-6, tumor necrosis factor-α, and C-reactive protein. These compounds have been associated with depressive symptoms, disturbances in neuroendocrine function, leaky gut, monoamine activity and brain function, while also being key factors in the development of cardiometabolic diseases. The Mediterranean diet (MD) in particular, is well supported by first-level evidence regarding its preventive qualities against metabolic and cardiovascular diseases and thus considered a model for healthy eating by various organizations. In one of the few clinical trials investigating these associations, the PREDIMED trial, individuals with diabetes assigned to a MD supplemented with mixed tree nuts experienced a 41% relative risk reduction for developing depression. Lastly, there is a need to include health related quality of life as an indicator of physical and mental well-being, considering its putative associations with depression and suicide risk. Going forward, focusing on clinical trials, using precise nutritional assessments, and identifying nutritional biomarkers which may be related to depression are needed to fully support the implementation of dietary recommendations in the field of psychiatry.
Genetic parameters of the traits recorded in the performance test of dual-purpose bulls

e data on 1 144 performance tested Czech Pied bulls born from 1991 to 1997 were analysed. e test started at 111 days of bulls' age and lasted until the age of 420 days. Simulation analysis was carried out for the age of bulls at the end of the test 210, 300, 330, 365, and 420 days. Genetic parameters were estimated for different test periods and the relationships between the periods were analysed. e heritability coefficients for live weights of young bulls recorded at different age ranged from h 2 = 0.20 to h 2 = 0.46. For average daily gains in different periods according to the simulated termination of the test, the estimated heritability coefficients ranged from h 2 = 0.20 to h 2 = 0.59. e genetic correlations between the test termination at 300 days of age and the termination at 330, 365 or 420 days ranged from r g = 0.88 to r g = 0.99 for live weight and from r g = 0.61 to r g = 0.91 for average daily gain. ese results support the idea to reduce considerably the duration of performance test in young bulls.
Physiological measurements in smart clothing: a case study of total body water estimation with bioimpedance

A wearable physiological bioimpedance measurement system has been designed and implemented. Measured bioimpedance values can be utilized for total body water (TBW) estimation. This information can be useful for, eg, athletes whose performance weakens due to dehydration. The system is integrated into a sport suit and its functionality has been tested by performing walking, fitness cycling and running tests. Also reference tests in a sauna have been performed. Altogether, nine persons have been participating in tests. During long-term exercising, TBW values were decreased. However, more tests are needed in order to analyse the measurement results accurately.
FEM/DEM Modelling of Hard Body Impact on the Laminated Glass

Laminated glass is widely used for structural members in industry. Among all loading types, impact is one of the most adverse forms due to its dynamic effect. In order to investigate how laminated glass fractures under hard body impact and the subsequent fragmentation, the combined finite-discrete element method (FEM/DEM) was employed in this paper. This method discretises a single discrete element in finite elements, giving a more accurate estimate of the contact forces and deformation of the elements. This paper presents the transient responses of a laminated glass beam under impact by using a simple mixed-mode (I + II) elasto-plastic fracture model developed for the FEM/DEM program. The results from this mixed-mode model has been compared and validated with that from Mode I fracture model. A parametric study on the laminated glass is performed based on the mixed-mode model, showing its better energy absorption capacity than monolithic glass and the influence of the interfacial strength on the damage behaviour, demonstrating that laminated glass is safer than the monolithic glass. It also shows that the FEM/DEM modelling and the new mixed-mode (I+II) model is applicable and provides realistic simulations.
Framework of Success Criteria for Design/Build Projects

Success has always been the ultimate goal of every activity, and a construction project is no exception. Due to the ambiguous definition of project success and the different perceptions of participants toward this concept, it may be difficult to tell whether a project is successful as there is a lack of consensus. Time, cost, and quality have long been the success criteria used to evaluate the performance of a construction project. However, such a list has been criticized as not being comprehensive. Even studies of the project success of a particular construction method, such as the design/build procurement system, are lacking in most previous research considering construction projects in general. This paper sets out to establish criteria for project success for a design/build project in construction, first by identifying relevant measures of project success for a construction project in past studies, with particular emphasis on design/build projects, and then by establishing a comprehensive assessment fr.
Hepatitis C infection and chronic kidney disease among Hispanics/Latinos

Supplemental Digital Content is available in the text Abstract Viral infections, including hepatitis C, can cause secondary glomerular nephropathies. Studies suggest that hepatitis C virus infection (HCV+) is a risk factor for chronic kidney disease (CKD) but evidence of this relationship is lacking among Hispanics/Latinos. We examined the association between HCV+ and incident CKD in a prospective cohort of Hispanics/Latinos enrolled in the Hispanic Community Health Study/Study of Latinos. HCV+ was defined by detectable HCV antibodies with additional confirmation through HCV RNA or recombinant immunoblot assay testing. Incident CKD was defined by an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 or sex-specific threshold for albuminuria measured during follow-up. We used Poisson regression to estimate incidence rate ratios (IRR) of CKD and changes in eGFR- or albuminuria-based risk stages, separately. We used linear regression to estimate associations with continuous, annualized changes in eGFR and albuminuria. Over a follow-up period of 5.9 years, 712 incident CKD events occurred among 10,430 participants. After adjustment for demographic characteristics and comorbidities, HCV+ was not associated with incident CKD, defined by eGFR and albuminuria thresholds (IRR 1.29, 95% Confidence Interval 0.61, 2.73). HCV+ was significantly associated with higher eGFR risk stages (IRR 2.39, 95% CI 1.47, 3.61) with most participants transitioning from stage G1 to G2. HCV+ was associated with a continuous, annualized eGFR decline of −0.69 mL/min/m2/year (95% CI −1.23, −0.16). This large, cohort study did not find evidence of a strong association between HCV+ and new-onset CKD among Hispanics/Latinos. HCV infection may not be associated with risk of CKD among Hispanics/Latinos, although treatment with direct-acting antivirals is recommended for all HCV+ individuals, including those with established CKD or end-stage kidney disease.
Vision-Based Augmented Reality System for Middle Ear Surgery: Evaluation in Operating Room Environment

Supplemental Digital Content is available in the text Hypothesis: Augmented reality (AR) solely based on image features is achievable in operating room conditions and its precision is compatible with otological surgery. Background: The objective of this work was to evaluate the performance of a vision-based AR system for middle ear surgery in the operating room conditions. Methods: Nine adult patients undergoing ossicular procedures were included in this prospective study. AR was obtained by combining real-time video from the operating microscope with the virtual image obtained from the preoperative computed tomography (CT)-scan. Initial registration between the video and the virtual CT image was achieved using manual selection of six points on the tympanic sulcus. Patient-microscope movements during the procedure were tracked using image-feature matching algorithm. The microscope was randomly moved at an approximated speed of 5 mm/s in the three axes of space and rotation for 180 seconds. The accuracy of the system was assessed by calculating the distance between each fiducial point selected on the video image and its corresponding point on the scanner. Results: AR could be obtained for at least 3 minutes in seven out of nine patients. The overlay fiducial and target registration errors were 0.38 ± 0.23 mm (n = 7) and 0.36 ± 0.15 mm (n = 5) respectively, with a drift error of 1.2 ± 0.5 μm/s. The system was stable throughout the procedure and achieved a refresh rate of 12 fps. Moderate bleeding and introduction of surgical instruments did not compromise the performance of the system. Conclusion: The AR system yielded sub-millimetric accuracy and remained stable throughout the experimental study despite patient-microscope movements and field of view obtrusions.
Determination of cytokine profile and associated genes of the signaling pathway in HNSCC

Abstract Head and neck squamose cell carcinoma (HNSCC) is an aggressive group of tumors that are generally heterogeneous. Despite treatment advances, disease-free survival has not significantly improved. Therefore, it is of great importance to understand the molecular etiology of HNSCC and genetic alterations in the signal pathways in order to develop new therapeutic approaches. In this study, firstly we used a cytokine array to analyze the secretomes of HNSCC patients and healthy controls. In the next step, the results from the cytokine sequence were validated by qRT-PCR and western blot, including genes in the associated signaling pathway. In array analysis, the levels of EGF, IGF-1, IGFBP-1, and PDGFBB were significantly higher in patients than in the controls. The results of qRT-PCR analyses showed that expression levels of PDGFRB gene were significantly up-regulated (p = 0.006) and PTEN (p > 0.001) were significantly down-regulated in tumors compared with normal tissues. When groups (early vs. advanced) were compared, higher expression of IGFBP-1 was observed in the larynx (p = 0.045) and larynx + oral cavity tumors (p = 0.010) in an advanced stage. In western blot analysis, pEGFR, pIGF-IR, pIR-β, pPDGFRB, and pAKT levels were upregulated, and pPTEN was downregulated in tumors. Based on our observations, determining the interactions of EGFR, PDGFRB, IGF-1R and PTEN or the activation of each might represent a promising new and innovative treatment approach in HNSCC patients. It seems clear that, in most cancers, effective targeted therapy may be involved the blockade of each one or multiple targets.
Association between a usual source of care and influenza vaccination rates among pregnant women

Pregnant women and infants less than 6 months of age have a higher risk of complications from influenza. Vaccination is recommended for pregnant women to decrease risk of infection and hospitalizations between both the women themselves and infants. However, vaccination rates remain low in pregnant women. The objective of this study was to determine the association between having a usual source of care and seasonal influenza vaccination rates among women who were pregnant between 2012 and 2016.

Long-Term Outcomes of Transarterial Radioembolization for Large Single Hepatocellular Carcinoma: A Comparison to Resection

Visual Abstract The surgical treatment for large hepatocellular carcinoma (HCC) remains controversial because of a high risk of recurrence after resection. This study aimed to compare long-term outcomes of transarterial radioembolization (TARE) with resection for patients with large HCC. Methods: This retrospective cohort study included 557 patients who were initially treated with either resection (n = 500) or TARE (n = 57) for large (≥5 cm), single nodular HCC at 2 tertiary centers in Korea. Patients with major portal vein tumor thrombosis or extrahepatic metastasis were excluded. The primary endpoint was overall survival (OS), and secondary endpoints were time to progression (TTP), time to intrahepatic progression (TTIP), and safety. Results: The resection group was younger (median, 60 vs. 69 y) and had a smaller tumor size (median, 7.0 vs. 10.0 cm) (all P < 0.05). After baseline characteristics were balanced using inverse-probability-of-treatment weighting, the OS (hazard ratio [HR], 0.98; 95% CI, 0.40–2.43; P = 0.97), TTP (HR, 1.10; 95% CI, 0.55–2.20; P = 0.80), and TTIP (HR, 1.45; 95% CI, 0.72–2.93; P = 0.30) of the TARE group was comparable to the resection group. TARE was not an independent risk for OS (adjusted HR, 1.04; 95% CI, 0.42–2.59; P = 0.93), TTP (adjusted HR, 0.98; 95% CI, 0.50–1.95; P = 0.96), or TTIP (adjusted HR, 1.30; 95% CI, 0.65–2.58; P = 0.46). The TARE group had a shorter hospital stay and fewer adverse events than the resection group. Conclusion: Compared with surgical resection for large single nodular HCC, TARE showed a comparable OS, TTP, and TTIP and a better safety profile.
Do skin suits affect the average skating speed

We analyze the effectiveness of speed skating suits to allow for increases in average skating speed. We used the full set of speed skating results of the 2002 Olympic Winter Games of Salt Lake City and modeled the average skating speed of both male and female speed skaters at distances from 500 to 10 000 m. Speed correlates with the physical characteristics of the skaters, past performance, and technical equipment, like speed skating suits that reduce drag. Nike's Swift Skin suit seems to outperform other suits in terms of results, but once corrected for selection bias, we found that none of the suits outperform the others.

Moving Vehicle Detection Using Time Domain Statistical Features

The Hearing Impaired People (HIP) cannot distinguish the sound from a moving vehicle approaching from their behind. Since, it is difficult for hearing impaired to hear and judge sound information and they often encounter risky situations while they are in outdoor. If HIPs can successfully get sound information through some machine interface, dangerous situation will be avoided. Generally the profoundly deaf people do not use any hearing aid which does not provide any benefit. This paper presents, simple statistical features are used to classify the vehicle type and its distance based on sound signature recorded from the moving vehicles. An experimental protocol is designed to record the vehicle sound under different environment conditions and also at different speed of vehicles. Basic statistical features such as the standard deviation, Skewness, Kurtosis and frame energy have been used to extract the features. Probabilistic neural network (PNN) models are developed to classify the vehicle type and its distance. The effectiveness of the network is validated through stimulation.
