Iterative based image and video denoising by fractional block matching and transform domain filtering

This paper presents an iterative algorithm for image and video denoising which is based on fractional block-matching and transform domain filtering. We propose fractional motion estimation technique to find the most accurate similar blocks for each block of an image which improves sparsity enabling effective image denoising. By taking the advantage of blocks similarity and wavelet transform domain filtering along with weighted average function (WAF) in an iterative based manner, we achieve a higher level of sparsity and a better exploiting of blocks similarity redundancies of noisy images that increase the chance of preserving details and edges in the restored image. Since our algorithm is iterative, we can tradeoff between image denoising degree and computational complexity. In addition, we develop a video denoising algorithm based on the proposed image denoising algorithm. The simulation results of images and videos contaminated by additive white Gaussian noise demonstrate that our algorithm substantially achieves better denoising performance compared with previously published algorithms in terms of subjective and objective measures.
Did the bank of Japan’s purchases of exchange-traded funds affect stock prices? A synthetic control approach

ABSTRACT This study investigates the effect of the Bank of Japan’s large-scale exchange-traded fund purchasing programme since 2013 on stock prices using a synthetic control method. We use the stock price indexes of 27 OECD countries as a control group and estimate the time-series data of the synthetic stock price index of Japan. The index in Japan increased gradually relative to the synthetic Japanese index from 2013. This result suggests that the Bank of Japan’s intervention in the stock market is distorting stock prices and should be reconsidered.
Ir-oriented nanocrystalline assemblies with high activity for hydrogen oxidation/evolution reactions in an alkaline electrolyte

In this study, we report successful synthesis of ultrafine worm-like Ir-oriented nanocrystalline assemblies (ONAs) and their further use as efficient electrocatalysts towards the HOR/HER in an alkaline medium. Due to the fast mass/charge transfer rate as well as the appearance of the long segments of low-index crystalline planes, the as-synthesized Ir ONAs exhibit a remarkable performance for the HOR/HER in an alkaline electrolyte.
Electroluminescence of superatom-like Ge-core/Si-shell quantum dots by alternate field-effect-induced carrier injection

We have fabricated high-density superatom-like Si–Ge-based quantum dots (Si-QDs with Ge core) and studied their luminescence properties. Electroluminescence was observed from the Si-QDs with Ge core at room temperature in the near-infrared region by the application of square-wave pulsed bias of ±1 V at 500 kHz, which was attributed to radiative recombination between quantized states in the Ge core with deep potential well for holes caused by field-effect-induced alternate electron/hole injection from the substrate. The results lead to the development of Si-based light-emitting devices that are highly compatible with ultra-large-scale integration processing, which was found difficult to realize in silicon photonics.
COVID-19 first lockdown as a unique window into language acquisition: What you do (with your child) matters.

The COVID-19 pandemic, and the resulting closure of daycare centers worldwide, led to unprecedented changes in children’s learning environments. This period of increased time at home with caregivers, with limited access to external sources (e.g., daycares) provides a unique opportunity to examine the associations between the caregiver-child activities and children’s language development. The vocabularies of 1742 children aged 8-36 months across 13 countries and 12 languages were evaluated at the beginning and end of the first lockdown period in their respective countries (from March to September 2020). Children who had less passive screen exposure and whose caregivers read more to them showed larger gains in vocabulary development during lockdown, after controlling for SES and other caregiver-child activities. Children also gained more words than expected (based on normative data) during lockdown; either caregivers were more aware of their child’s development or vocabulary development benefited from intense caregiver-child interaction during lockdown.
Measuring Internet Gaming Disorder and Gaming Disorder: A Qualitative Content Validity Analysis of Validated Scales

Numerous instruments have been developed to measure gaming-related health problems based on “internet gaming disorder” (IGD) in the third section of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) and “gaming disorder” (GD) in the International Classification of Diseases (11th rev.). However, the criteria in the manuals tend to be operationalized in numerous diverse ways, which can make screening outcomes incomparable. A content validity analysis is needed to reassess the relationships between the diagnostic criteria and the items that operationalize them. The IGD and GD criteria were divided into sematic components. A qualitative content validity analysis was carried out for all items employed by the 17 instruments that claim to measure either construct by their criteria in English. In all but one instrument, the operationalizations did not include all criterion components. There were two main reasons found for this: the components had simply been left out or had been alternatively modified into other components. Criteria that were vaguely described in the manuals were sources of lower content validity items. The study implies that many of the problems in IGD and GD measurement derive from criteria operationalization and original manual descriptions. The conclusion provides practical recommendations that researchers can apply to improve the content validity of their measurement.

A novel aptasensor for malathion blood samples detection based on DNA–silver nanocluster

Pesticides have drawn great attention because of their bad effects on health and the environment. Among these, organophosphates were the most widely used in China and malathion is the most common. Direct or indirect contact with malathion does harm to our nervous, respiratory and digestive systems. Thus, accurate detection of malathion in biological samples is very useful to ensure the safety of human health, especially in agricultural countries. In this paper, a sensitive and selective aptasensor based on DNA–silver nanocluster probes has been proposed for the simple and efficient detection of malathion in biological samples. First its feasibility was verified when the UV-vis absorbance apparently decreased with inclusion of malathion and the response differed from that with other chemicals. Then under optimized conditions, a concurrent decrease in absorbance with the addition of malathion from 0 μg mL−1 to 25 μg mL−1 was achieved with a limit of detection of 25 pg mL−1. The linear equations between the UV-vis absorbance spectrum and the concentration of malathion were y = 10.167x + 1.051, R2 = 0.986 (range from 0.000025 μg mL−1 to 0.025 μg mL−1) and y = 0.0136x + 1.431, R2 = 0.995 (range from 0.25 μg mL−1 to 25 μg mL−1). Moreover, investigations in blood samples were conducted to test the biocompatibility of the aptasensors for the sake of practical applications in forensic research. The detection results of the proposed method were almost consistent with those of conventional high-performance liquid chromatography (HPLC). In view of its simplicity, low cost, selectivity, sensitivity and reliability, the aptasensor introduced in our work may potentially be a better way to detect malathion in forensic toxicology examination.
Molecular simulations of the structure and thermal transport of high alumina aluminosilicate molten core glass fiber

Correspondence Stephen H. Garofalini, Department of Materials Science and Engineering, Rutgers University, Piscataway, NJ. Email: shg@rutgers.edu Abstract The atomistic structure and phonon transport in aluminosilicate glasses made via an interfacial mixing model of the Molten Core process were studied using molecular dynamics simulations. In the simulations, silica glass was brought in contact with different size alumina crystals (to afford core glasses with 4, 18, 24, 29, and 41 mole% alumina concentrations), followed by a melt-quench process to enable mixing of the phases. The atomistic structure of the resulting glasses and radius of gyration calculations of resultant Al-O-Al connected clusters were evaluated. Variation in the 1-dimensional thermal transport in each glass was also determined and showed that increased alumina concentration in the glasses resulted in increased transport of thermal energy. Results of the structural analyses showed a double peak in the Al-Al pair distribution function, with the short-distance peak indicative of edge-sharing Al-O-Al-O bonding and a longer distance peak of Al-O-Al bonding that is not indicative of edge-sharing structures. The ratio of the first Al-Al peak to the second Al-Al peak varied inversely with the thermal transport behavior. An increased radius of gyration of Al-O-Al connectivity occurred with increasing alumina concentration, providing a mechanism for the increased thermal transport. Nanosegregation was also observed. Interconnectivity between Al ions created isolated Al-O-Al bonded clusters at low alumina concentrations with lower thermal transport than the high alumina glasses, whereas the latter showed a percolated network of Al-O-Al bonds that increased thermal transport.
Quality Assessment of Microbial Load in Raw Poultry Meat from Retail Meat Outlets of Bikaner

Poultry, or domestic birds, are raised for their meat and eggs and are important source of edible animal protein that accounts 30% of global meat consumption. The popularity of poultry meat has been on the rise during the last two decades and is the most popular meat from any single livestock species. Poultry is a food that has been highly appreciated by man since time immemorial and it is a good source of protein, vitamin B12 and minerals, such as iron, selenium and zinc. Poultry meat is also rich in the omega-3 fats and is an important provider of the essential polyunsaturated fatty acids (PUFA), and animal protein (FAO, 2010).
The Effects of Oxidative Stress on Calcineurin Activity and DJ-1 Subcellular Localization

Oxidative stress and mutations in DJ-1, a redox sensitive protein, are linked to Parkinson's Disease. The protective mechanism of DJ-1 is unclear. I hypothesized that: 1) DJ-1 mediates protection by translocating to mitochondria after oxidative stress and, 2) when DJ-1 is downregulated, apoptotic pathways regulated by calcineurin are also downregulated. In PC12 cells and rat cortical neurons, oxidative stress resulted in the upregulation of DJ-1 and increased DJ-1 in the nucleus, but did not increase mitochondrial translocation of DJ-1. In cortical neurons and wildtype mouse embryonic fibroblasts, H2O2 induced cleavage of CnA into an inactive fragment. DJ-1 knockout fibroblasts had less nuclear localization of the transcription factor NFATc4, a substrate of calcineurin involved in apoptosis. H2O2 increased CnA cleavage in DJ-1 knockout fibroblasts, but NFATc4 localization was unchanged. These results suggest that the downregulation of apoptotic pathways regulated by calcineurin may be a compensatory response to the downregulation of DJ-1.

Chemical analysis of dietary supplements

The increased use of dietary supplements in today's society has been attributed to the general public's greater awareness of what constitutes a healthy diet. The elemental content (Ca, Cd, Cr, Co, Cu, Fe, Mg, Mn, Mo, Ni, Pb and Zn) of seventy-four dietary supplements (tablets, capsules and powders) was analysed by inductively coupled plasma mass spectrometry (ICP-MS). Different digestion methods (wet open vessel and microwave) were developed for the dissolution of dietary supplements, utilising both concentrated nitric acid and hydrogen peroxide. Both digestion procedures were found to give no significant statistical difference between the experimental results and certified values at a 99% confidence limit (Paired t-test) for all element values in two certified reference materials, namely NIES Rice Flour and IGGE Tea. For both certified reference materials, there was. The elemental content of the dietary supplements ranged from 0.1-200 mg/g for macro essential elements (Ca, Fe and Mg), 1-500 mug/g for trace essential elements (Cr, Co, Cu, Mn. Mo, Ni and Zn) and 0.4-10 mug/g for non-essential elements (Cd and Pb), all on a dry weight basis. Comparison of experimental results with commercial label values for dietary supplements showed: (1) calculated Ca and Mg concentrations were systematically lower than the label values; and (2) the experimental results for the other essential elements were in good agreement. The essential element contribution of base materials was investigated, though the results were inconclusive. Dietary supplements containing fat-soluble vitamins were analysed for retinol acetate, ergocalciferol (D2), cholecalciferol (D3), tocopherol (E), tocopherol acetate and phylloquinone (K1) using a modified simultaneous high performance liquid chromatography (HPLC) method. For each vitamin, a recovery of >90% was obtained with the use of a direct solvent extraction procedure. An in vitro study into the bioavailability of iron and zinc in yeast-based supplements was accomplished. This study provided results suggesting that iron supplements containing vitamin C were more bioavailable than yeast or tablet-based supplements that contained no vitamin C. Zinc bioavailability was observed to be greater in multi-component and yeast-based dietary supplements.
Community-Based Interventions for Cardiovascular Disease Prevention in Low-and Middle-Income Countries: A Systematic Review

Objectives: To synthesize evidence on the effectiveness of community-based interventions for cardiovascular disease (CVD) prevention in low- and middle-income countries (LMICs) to inform design of effective strategies for CVD prevention. Methods: We searched MEDLINE, EMBASE, CINAHL, Cochrane register of controlled studies and PSYCINFO databases for studies published between January 2000 and June 2019. Other studies were identified from gray literature sources and review of reference lists of included studies. The primary outcomes for the review were those aimed at primary prevention of CVD targeting physical activity, diet, smoking and alcohol consumption. Results: Database searches yielded 15,885 articles and 94 articles were identified through snowball searching. After screening, the articles from LMICs were 32 emanating from 27 studies: 9 cluster randomized trials, eight randomized controlled trials and 10 controlled before and after studies. Community-based interventions successfully improved population knowledge on CVD and risk factors and influenced physical activity and dietary practices. Evidence of interventions on smoking cessation and reduced alcohol consumption was inconsistent. Conclusion: This evidence should inform policy makers in decision-making and prioritizing evidence-based interventions.
Effect of Perceived Organizational Support on Fatigue of Chinese Nurses during the COVID-19 Pandemic: Resilience as a Mediator

As working for the nurse is believed to be one of the most stressful professions, nurses are particularly at risk of experiencing fatigue. Especially during the COVID-19 pandemic, fatigue among nurses may affect physical and mental health seriously, which is attracting increasing attention of researchers and clinical practitioners to find effective prevention measures to alleviate nurses' fatigue. This study aims to investigate the mediational effect of resilience on the relationship between nurses' perceived organizational support and fatigue. A total of 476 nurses from secondary and above hospitals in Hebei province, China during March and April in 2020, were investigated with Perceived Organizational Support Scale, Resilience Scale and Work Fatigue Inventory. Structural equation modeling was conducted to explore the mechanisms of nurses' perceived organizational support on fatigue. Results revealed that perceived organizational support can decrease the nurses' mental/physical/emotional fatigue through the mediating role of resilience. These findings guide for hospital managers to identify effective prevention strategies to alleviate the fatigue of clinical nurses.

Surveillance Video Key Frame Extraction Based on Center Offset

: With the explosive growth of surveillance video data, browsing videos quickly and effectively has become an urgent problem. Video key frame extraction has received widespread attention as an effective solution. However, accurately capturing the local motion state changes of moving objects in the video is still challenging in key frame extraction. The target center offset can reflect the change of its motion state. This observation proposed a novel key frame extraction method based on moving objects center offset in this paper. The proposed method utilizes the center offset to obtain the global and local motion state information of moving objects, and meanwhile, selects the video frame where the center offset curve changes suddenly as the key frame. Such processing effectively overcomes the inaccuracy of traditional key frame extraction methods. Initially, extracting the center point of each frame. Subsequently, calculating the center point offset of each frame and forming the center offset curve by connecting the center offset of each frame. Finally, extracting candidate key frames and optimizing them to generate final key frames. The experimental results demonstrate that the proposed method outperforms contrast methods to capturing the local motion state changes of moving objects.
