Due to the inability of manufacturing a single monolithic mirror at the 10-meter scales,segmented mirrors have become indispensable tools in modern astronomical research.However,to match the imaging performance of the monolithic counterpart,the sub-mirrors must maintain precise co-phasing.Piston error critically degrades segmented mirror imaging quality,necessitating efficient and precise detection.To ad-dress the limitations that the conventional circular-aperture diffraction with two-wavelength algorithm is sus-ceptible to decentration errors,and the traditional convolutional neural networks(CNNs)struggle to capture global features under large-range piston errors due to their restricted local receptive fields,this paper pro-poses a method that integrates extended Young’s interference principles with a Vision Transformer(ViT)to detect piston error.By suppressing decentration error interference through two symmetrically arranged aper-tures and extending the measurement range to±7.95μm via a two-wavelength(589 nm/600 nm)algorithm.This approach exploits ViT’s self-attention mechanism to model global characteristics of interference fringes.Unlike CNNs constrained by local convolutional kernels,the ViT significantly improves sensitivity to inter-ferogram periodicity.The simulation results demonstrate that the proposed method achieves a measurement accuracy of 5 nm(0.0083λ0)across the range of±7.95μm,while maintaining an accuracy exceeding 95%in the presence of Gaussian noise(SNR≥15 dB),Poisson noise(λ≥9 photons/pixel),and sub-mirror gap er-ror(Egap≤0.2)interference.Moreover,the detection speed shows significant improvement compared to the cross-correlation algorithm.This study establishes an accurate,robust framework for segmented mirror error detection,advancing high-precision astronomical observation. 展开更多

With the transformation from websites to Internet platforms, Chinese young netizens (born in 1990-2005) have become key subjects in the evolution of cyber-nationalism. Based on survey data, this study classifies their nationalism into four types and explores its transformation alongside globalization cognition. The result shows that moderate nationalism is the mainstream. This has raised their attention to globalization, with greater focus on relations between China and developing countries, and nations along the Belt and Road Initiative. Their personal experiences and cultural exposure foster a more inclusive global vision, shaping the evolution of nationalism and global dialogue. 展开更多

Background:Early Hearing Detection and Intervention(EHDI)plays a critical role in improving language,cognitive,and socio-emotional outcomes for infants with hearing loss.In Nigeria,however,EHDI implementation remains limited by fragmented service delivery,uneven technological capacity,and sociocultural factors that delay timely diagnosis.This study explored the perspectives of paediatric audiologists and parents to provide a comprehensive understanding of the opportunities and challenges influencing early hearing care across diverse Nigerian settings.Methods:A mixed-methods design was employed across audiology facilities selected systematically from four Nigerian geopolitical zones.Twenty-five paediatric audiologists and twenty-three parents of children with congenital hearing loss participated.Quantitative data were collected using a structured questionnaire assessing awareness,diagnostic access,and intervention experiences.Qualitative data were obtained through semi-structured interviews and two focus group discussions.Thematic analysis followed Braun and Clarke's six-step framework,with dual coding,external auditing,and member validation to enhance credibility.Results:Quantitative findings demonstrated broad agreement on the diagnostic value of otoacoustic emissions(OAEs)and automated auditory brainstem responses(AABRs),the developmental benefits of early intervention,and the importance of active parental involvement.However,respondents identified persistent barriers including high costs of screening and therapy,poor public awareness of early hearing loss symptoms,and a critical shortage of trained personnel,and unequal distribution of diagnostic tools,particularly in rural and northern regions.Thematic analysis further underscored disparities in diagnostic capacity,sociocultural interpretations of deafness that delay clinical consultation,and economic constraints that hinder continuity of care.While families who accessed early intervention reported improved communication,social engagement,and learning readiness in their children,systemic gaps continue to limit widespread success.Conclusions:Despite growing technological capacity and awareness of EHDI benefits,significant structural,financial,and sociocultural challenges continue to impede timely diagnosis and intervention in Nigeria.Strengthening national policies,ensuring equitable distribution of diagnostic tools,expanding professional training,subsidising services,implementing culturally sensitive awareness campaigns and integration of Universal Newborn Hearing Screening into routine postnatal care are essential to improving outcomes for deaf infants. 展开更多

Triacylglycerol(TAG)components in human milk,infant formulas with different fat sources,and plant oils(palm oil,flaxseed oil,sunflower oil,corn oil,soybean oil,coconut oil,low erucic acid rapeseed oil,and high oleic acid rapeseed oil)were analyzed and compared using ultraperformance supercritical fluid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPSFC-Q-TOF-MS).Distinct TAG profiles were identified by lipidomics,principal component analysis(PCA),and heatmap visualization.Human milk was characterized by a high abundance of medium-and long-chain triacylglycerols(MLCTs),saturated-unsaturated-unsaturated(SUU)-type TAGs(sn-2 palmitic acid).In contrast,plant oils lacked MLCTs and SUU-type TAGs,containing mainly TAGs esterified long-chain polyunsaturated fatty acid.Breast milk contains about 27%MLCT,about 50%SUU-type triacylglycerols(which contain about 34%UPU-type triacylglycerols),which is significantly different from plant oils,structured fats and infant formulas.These findings provide a clear basis for optimizing the fat blend in infant formula to better mimic the unique TAG profile of human milk,thereby improving energy delivery and nutrient absorption for infants. 展开更多

Both linoleic acid(18:2 n-6,LA)andα-linolenic acid(18:3 n-3,ALA)are essential fatty acids for infants.The contents of LA and ALA,and their ratio exhibited significant changes in human milk over the past 4 decades,which were not well summarized.Here,we summarized these values in 9898 human breast milk samples of 6664 mothers from 50 countries in 81 studies.A literature search was conducted using PubMed,Embase,and Web of Science between January 1980 and October 2023.The 95%confidence interval of LA/ALA ratio across lactation and gestation ranged from 14.24 to 31.26.The LA content was higher in China and Turkey(>20%)whereas the ALA content was below 1%in Africa.The LA/ALA ratio in countries along the Mediterranean coast exceeded 20 or even 30.LA and ALA contents increased significantly(P<0.01)while the ratio remained stable over the last 40 years.Multivariate meta-regression results showed that regions significantly(P<0.01)determined the LA,ALA,and LA/ALA ratio.Especially,maternal diet could definitely explain the variation while the effects of gestational age,lactation period was not significant.Clinical trials demonstrated that decreasing the LA/ALA ratio increased docosahexaenoic acid(22:6 n-3,DHA)status,reduced arachidonic acid(20:4 n-6,AA)contents,exerted no effect on the visual function of infants,and reached no consensus on growth.The current review aims to provide an overview on the LA and ALA contents and their ratio in human breast milk to raise concern in infant formula. 展开更多

Objective To assess the effectiveness of complementary food supplements with protein and multi-micronutrients on hemoglobin and anemia in infants and young children. Methods In 5 poor counties of Gansu, 984 children aged 6-12 months were enrolled and divided into two groups. In addition to the usual home-made complementary food, all the children were fed one sachet of either Formula Ⅰ or Formula Ⅱ supplements each day. Protein and micronutrients were provided in Formula Ⅰ, while the same energy intake was secured in Formula Ⅱ as in Formula Ⅰ. A massive dose of vitamin A was supplemented to all the children every 6 months. Hemoglobin test was done at the same time. Results Prevalence of anemia was about 35% in both Formula Ⅰ and Formula Ⅱ group at baseline, and there were no differences in hemoglobin concentration between the two groups, During the 6-month and 12-month supplementation, hemoglobin of children in Formula Ⅰ group was higher than that in Formula Ⅱ group (P〈0.05), and hemoglobin increase in Formula Ⅰ group was significantly higher than that in Formula Ⅱ group (P〈0.001). After 6- and 12-mouth supplementation, the prevalence of anemia in Formula Ⅰ group dropped to 19.1% and 8.2% respectively, and it was 28.0% and 12.4% in Formula 2 group. The prevalence of anemia in Formula Ⅰ group was significantly lower than that in Formula Ⅱ group (P〈0.05). After adjusting age and hemoglobin level at baseline, the hemoglobin increase at age of 24 months in formula 1 group was higher (10.7 g/L vs 7.9 g/L, P〈0.0001). Conclusion Micronutrient fortified complementary food supplements, with large-dose vitamin A, is effective for children aged 6-12 months in terms of iron deficiency prevention. 展开更多

Objective To understand the status and problems of complementary feeding and to explore the strategy of improving complementary feeding for infants and young children in China. Method Data of urban and rural children were selected from the China Food and Nutrition Surveillance System (CFNSS) dataset to describe the status of complementary feeding and growth of children. Logistic Regression was used to analyze the relationship between child growth and the complementary feeding pattern. Results Applications of foods that come from animals, vegetable/fruit and dairy product in complementary feeding were negatively correlated to the prevalence of stunting and underweight. Attributable risk (AR) of no application of vegetable/fruit in complementary feeding to stunting was 30.2%, to underweight 35.4%; AR of no application of foods from animal products in complementary feeding to stunting was 28.2%, to underweight 11.7%; and the AR of no application of diary products in complementary feeding to stunting was 27.4%, to underweight was 15.9%. Conclusion Complementary feeding contributed to the improvement of infants and young children growth in China. There is an urgent need to develop health education in the public on infants and young children complementary feeding, in the mean time, it is pressing to pay attention and take actions to develop and promote affordable, acceptable, and accessible fortified complementary food in rural areas of China. 展开更多

Since infant and young child feeding practices play an important role in ameliorating childhood nutrition, an exploratory and descriptive study has thus been conducted employing a previously developed questionnaire at Ad-din shisu Hospital, Jashore, Bangladesh to obtain better insights about the breastfeeding and complementary feeding practices among infant and young child feeding caregivers. Out of 260 babies, 54% were female and 46% were male. Nearly all caregivers were found having the idea that breast milk is the best food for newborn babies. Around 81.9% of caregivers think that breast milk contains all the nutrients the baby needs to flourish, but in case of protection from disease, only 18.1% of caregivers think that it protects the baby from certain diseases. Around 46.9% mothers practiced early initiation of breastfeeding and they offered breast milk to their newborn right away (within one hour) after delivery, 53.5% lactating mothers had proper knowledge about breastfeeding methods, 39.6% mothers never practiced burping after breastfeeding, 66.4% mothers had normal delivery, 33.6% mothers had caesarian section, 99% mothers offered colostrums to their babies and only 1% of them didn’t give the colostrums. Besides, 88.8% continued breastfeeding up to 24 months or more along with 83.8% caregivers starting complementary feeding from six months, 55.4% caregivers said baby’s immune system is less developed, so they get attacked by infection easily and 44.6% caregivers said “their tummies are vulnerable to infection”, and 48.8% of the caregivers followed the type of hygiene required. Our findings revealed information on the knowledge, attitude, and practices of the caregiver’s towards breastfeeding and complementary feeding. 展开更多

Only about 25% of babies are exclusively breast fed until six months of age in developing countries though they are at a greater risk of infection and infant mortality. The Global Strategy for Maternal, Infant and Young Child Feeding (MI- YCF) Strategy developed by WHO/UNICEF in 2002 was to revitalize world attention to the impact of feeding practices on the nutritional status, growth, development, health and survival of infants and children. The data for this case study was collected through key informant interviews, observations and review of Save the Children nutrition programme reports and surveys. This information was then organized to produce a detailed description of the maternal, infant and young child nutrition programme in Habaswein and Wajir South districts or sub-counties. The maternal and infant young child nutrition (MIYCN) programme was launched in Habaswein and Wajir South districts in January 2012. The MIYCN programme followed recommendations of a Knowledge, Practice and Coverage (KPC) survey report in July 2012. To date, the programme has formed 48 Mother-to-mother Support Groups (MTMSGs), which are actively promoting the uptake of the recommended MIYCN practices in the community. MIYCN indicators have been markedly improved between July 2011 and February 2013 when surveys were conducted. The uptake of kitchen gardening has picked up significantly at Meri site and some mothers now have a changed attitude towards unskilled home deliveries and are conducting referrals for skilled births. The marked improvements in the performance of MIYCN indicators between July 2011 and February 2013 inWajir South and Habaswein districts can be partly attributed to the MIYCN programme established in January 2012. However, a randomized community trial is still required to provide conclusive results on the impact of care support groups on maternal, infant and young child feeding in this region. 展开更多
