Indigenous noble gases in the Moon’s interior
Authors: Will Patrizia , Busemann Henner , Riebe My E. I. , Maden Colin
Published: August 2022

The origin of volatiles in the Moon’s interior is debated. Scenarios range from inheritance through a Moon-forming disk or “synestia” to late accretion by meteorites or comets. Noble gases are excellent tracers of volatile origins. We report analyses of all noble gases in paired, unbrecciated lunar mare basalts and show that magmatic glasses therein contain indigenous noble gases including solar-type He and Ne. Assimilation of solar wind (SW)–bearing regolith by the basaltic melt or SW implantation into the basalts is excluded on the basis of the petrological context of the samples, as well as the lack of SW and “excess
40
Ar” in the magmatic minerals. The absence of chondritic primordial He and Ne signatures excludes exogenous contamination. We thus conclude that the Moon inherited indigenous noble gases from Earth’s mantle by the Moon-forming impact and propose storage in the incompatible element-enriched (“KREEP”) reservoir.

Electronic devices with engineered three-dimensional (3D) architectures are indispensable for frictional-force sensing, wide-field optical imaging, and flow velocity measurement. Recent advances in mechanically guided assembly established deterministic routes to 3D structures in high-performance materials, through controlled rolling/folding/buckling deformations. The resulting 3D structures are, however, mostly formed on planar substrates and cannot be transferred directly onto another curved substrate. Here, we introduce an ordered assembly strategy to allow transformation of 2D thin films into sophisticated 3D structures on diverse curved surfaces. The strategy leverages predefined mechanical loadings that deform curved elastomer substrates into flat/cylindrical configurations, followed by an additional uniaxial/biaxial prestretch to drive buckling-guided assembly. Release of predefined loadings results in an ordered assembly that can be accurately captured by mechanics modeling, as illustrated by dozens of complex 3D structures assembled on curved substrates. Demonstrated applications include tunable dipole antennas, flow sensors inside a tube, and integrated electronic systems capable of conformal integration with the heart.

Current debate surrounds the promise of neuroscience for education, including whether learning-related neural changes can predict learning transfer better than traditional performance-based learning assessments. Longstanding debate in philosophy and psychology concerns the proposition that spatial processes underlie seemingly nonspatial/verbal reasoning (mental model theory). If so, education that fosters spatial cognition might improve verbal reasoning. Here, in a quasi-experimental design in real-world STEM classrooms, a curriculum devised to foster spatial cognition yielded transfer to improved verbal reasoning. Further indicating a spatial basis for verbal transfer, students’ spatial cognition gains predicted and mediated their reasoning improvement. Longitudinal fMRI detected learning-related changes in neural activity, connectivity, and representational similarity in spatial cognition–implicated regions. Neural changes predicted and mediated learning transfer. Ensemble modeling demonstrated better prediction of transfer from neural change than from traditional measures (tests and grades). Results support in-school “spatial education” and suggest that neural change can inform future development of transferable curricula.
Concentration-dependent transcriptional switching through a collective action of cis-elements

Published: August 2022

Gene expression specificity of homeobox transcription factors has remained paradoxical. WUSCHEL activates and represses
CLAVATA3
transcription at lower and higher concentrations, respectively. We use computational modeling and experimental analysis to investigate the properties of the cis-regulatory module. We find that intrinsically each cis-element can only activate
CLAVATA3
at a higher WUSCHEL concentration. However, together, they repress
CLAVATA3
at higher WUSCHEL and activate only at lower WUSCHEL, showing that the concentration-dependent interactions among cis-elements regulate both activation and repression. Biochemical experiments show that two adjacent functional cis-elements bind WUSCHEL with higher affinity and dimerize at relatively lower levels. Moreover, increasing the distance between cis-elements prolongs WUSCHEL monomer binding window, resulting in higher
CLAVATA3
activation. Our work showing a constellation of optimally spaced cis-elements of defined affinities determining activation and repression thresholds in regulating
CLAVATA3
transcription provides a previously unknown mechanism of cofactor-independent regulation of transcription factor binding in mediating gene expression specificity.
Plasticity in astrocyte subpopulations regulates heroin relapse
Authors: Kruyer Anna , Angelis Ariana , Garcia-Keller Constanza , Li Hong , Kalivas Peter W.
Published: August 2022

Opioid use disorder (OUD) produces detrimental personal and societal consequences. Astrocytes are a major cell group in the brain that receives little attention in mediating OUD. We determined how astrocytes and the astroglial glutamate transporter, GLT-1, in the nucleus accumbens core adapt and contribute to heroin seeking in rats. Seeking heroin, but not sucrose, produced two transient forms of plasticity in different astroglial subpopulations. Increased morphological proximity to synapses occurred in one subpopulation and increased extrasynaptic GLT-1 expression in another. Augmented synapse proximity by astroglia occurred selectively at D2-dopamine receptor–expressing dendrites, while changes in GLT-1 were not neuron subtype specific. mRNA-targeted antisense inhibition of either morphological or GLT-1 plasticity promoted cue-induced heroin seeking. Thus, we show that heroin cues induce two distinct forms of transient plasticity in separate astroglial subpopulations that dampen heroin relapse.

Published: August 2022

Developing robust microwave-field sensors is both fundamentally and practically important with a wide range of applications from astronomy to communication engineering. The nitrogen vacancy (NV) center in diamond is an attractive candidate for such purpose because of its magnetometric sensitivity, stability, and compatibility with ambient conditions. However, the existing NV center–based magnetometers have limited sensitivity in the microwave band. Here, we present a continuous heterodyne detection scheme that can enhance the sensor’s response to weak microwaves, even in the absence of spin controls. Experimentally, we achieve a sensitivity of 8.9 pT Hz

for microwaves of 2.9 GHz by simultaneously using an ensemble of

Introduction

Improving hospital oxygen systems can improve quality of care and reduce mortality for children, but we lack data on cost-effectiveness or sustainability. This study evaluated medium-term sustainability and cost-effectiveness of the Nigeria Oxygen Implementation programme.

Methods

Prospective follow-up of a stepped-wedge trial involving 12 secondary-level hospitals. Cross-sectional facility assessment, clinical audit (January–March 2021), summary admission data (January 2018–December 2020), programme cost data. Intervention: pulse oximetry introduction followed by solar-powered oxygen system installation with clinical and technical training and support. Primary outcomes: (i) proportion of children screened with pulse oximetry; (ii) proportion of hypoxaemic (SpO2<90%) children who received oxygen. Comparison across three time periods: preintervention (2014–2015), intervention (2016–2017) and follow-up (2018–2020) using mixed-effects logistic regression. Calculated cost-effectiveness of the intervention on child pneumonia mortality using programme costs, recorded deaths and estimated counterfactual deaths using effectiveness estimates from our effectiveness study. Reported cost-effectiveness over the original 2-year intervention period (2016–2017) and extrapolated over 5 years (2016–2020).

Results

Pulse oximetry coverage for neonates and children remained high during follow-up (83% and 81%) compared with full oxygen system period (94% and 92%) and preintervention (3.9% and 2.9%). Oxygen coverage for hypoxaemic neonates/children was similarly high (94%/88%) compared with full oxygen system period (90%/82%). Functional oxygen sources were present in 11/12 (92%) paediatric areas and all (8/8) neonatal areas; three-quarters (15/20) of wards had a functional oximeter. Of 32 concentrators deployed, 23/32 (72%) passed technical testing and usage was high (median 10 797 hours). Estimated 5-year cost-effectiveness US$86 per patient treated, $2694–4382 per life saved and $82–125 per disability-adjusted life year-averted. We identified practical issues for hospitals and Ministries of Health wishing to adapt and scale up pulse oximetry and oxygen.

Conclusion

Hospital-level improvements to oxygen and pulse oximetry systems in Nigerian hospitals have been sustained over the medium-term and are a highly cost-effective child pneumonia intervention.
Outcome disparities in patients with atrial fibrillation based on insurance plan and educational attainment: a nationwide, multicenter and prospective cohort trial
Authors: Apiyasawat Sirin , Thongsri Tomon , Jongpiputvanich Kulyot , Krittayaphong Rungroj
Published: August 2022

Background

Atrial fibrillation (AF) is a complex disease. The management of AF requires continuous patient engagement and integrative healthcare.

Objectives

To explore the association between adverse AF-related clinical outcomes and the following two sociodemographic factors: educational attainment and insurance plan.

Design

A nationwide, prospective, multicenter, cohort trial.

Setting

National registry of 3402 patients with non-valvular AF in Thailand.

Participants

All patients enrolled in the registry, except those with missing information on educational attainment or insurance plan. Finally, data from 3026 patients (mean age 67 years, SD 11.3; 59% male sex) were analysed.

Primary outcomes

Incidences of all-cause mortality, ischaemic stroke and major bleeding during the 36-month follow-up period. Survival analysis was performed using restricted mean survival time (RMST) and adjusted for multiple covariates. The levels of the educational attainment were as follows: no formal education, elementary (grade 1–6), secondary (grade 7–12) and higher education (tertiary education).

Results

The educational attainment of the majority of patients was elementary (N=1739, 57.4%). The predominant health insurance plans were the Civil Servant Medical Benefit Scheme (N=1397, 46.2%) and the Universal Coverage Scheme (N=1333, 44.1%). After 36 months of follow-up, 248 patients died (8.2%), 95 had ischaemic stroke (3.1%) and 136 had major bleeding (4.5%). Patients without formal education died 1.78 months earlier (adjusted RMST difference −1.78; 95% CI, −3.25 to −0.30; p=0.02) and developed ischaemic stroke 1.04 months sooner (adjusted RMST difference −1.04; 95% CI, −2.03 to −0.04; p=0.04) than those attained a level of higher education. There were no significant differences in RMSTs for all three clinical outcomes when considering the type of health insurance plan.

Conclusion

Educational attainment was independently associated with all-cause mortality and ischaemic stroke in patients with AF, but adverse clinical outcomes were not related to the types of health insurance in Thailand.

Authors: Burton Amy Leigh , Hamilton Blake , Iorfino Frank , La Monica Haley M , Scott Elizabeth M , Hickie Ian B
Published: August 2022

Objectives

The aim of this study was to determine the prevalence of disordered eating in young people attending a headspace centre, an enhanced primary care centre providing early intervention services for mental health disorders for young people aged 12–25 years, in metropolitan Sydney.

Design

Cross-sectional assessment of disordered eating symptoms and behaviours.

Setting

An enhanced primary care youth mental health service in inner urban Sydney, Australia.

Participants

A sequential cohort of 530 young people aged 14–26 years presenting to headspace Camperdown for support with mental health concerns.

Outcome measures

Participants completed a series of questionnaires online which included items assessing the presence of eating disorder symptoms and behaviours.

Results

Over one-third of young people aged 14–26 years presenting to headspace Camperdown in a 22-month period reported symptoms of disordered eating. Of these, 32% endorsed overeating behaviours, 25% endorsed dietary restriction and 8% reported purging behaviours. In total, 44% reported engaging in one of more of these behaviours on a regular basis. Almost half reported experiencing significant shape and weight concerns. Eating disorder behaviours were particularly prevalent among female and gender-diverse participants (48% of females and 46% of gender-diverse participants compared with 35% of males) and overall scores across all of the eating disorder and body image items assessed were significantly higher for female participants compared with males.

Conclusions

Disordered eating behaviours and symptoms are common among those presenting to youth mental health primary care services. Proactive screening for these behaviours presents opportunities for early detection and specific interventions.

Using historical cardiac troponins to identify patients at a high risk of myocardial infarction
Authors: Roos Andreas , Edgren Gustaf
Published: August 2022

Objective

Many patients who present with chest pain have previous measurements of high-sensitivity cardiac troponin T (hs-cTnT). The clinical usefulness of incorporating these measurements in identifying patients who are at a high risk of myocardial infarction (MI) is unknown. We investigated if the relative change between a historical hs-cTnT and the admission hs-cTnT could improve early identification of patients with a high risk of MI.

Methods

We included all patients presenting with chest pain to seven different emergency departments (EDs) in Sweden from December 2009 to December 2016, who had at least one hs-cTnT measurement at the presentation and at least one available prior measurement. We used logistic regression to investigate the diagnostic performance of using various combinations of current and historical hs-cTnT measurements in diagnosing MI within 30 days.

Results

A total of 27 809 visits were included, among whom 2686 (9.7%) had an MI within 30 days. A cut-off value for historical hs-cTnT-adjusted admission hs-cTnT with similar specificity (91.2%) as an admission hs-cTnT of ≥52 ng/L identified 4% more MIs (43% vs 39%) and had a higher positive predictive value, 42.6% (95% CI, 41.0% to 44.3%) vs 38.9% (95% CI 37.4% to 40.4%), as well as a higher positive likelihood ratio, 6.95 (95% CI 6.69 to 7.22) vs 5.95 (95% CI 5.73 to 6.18). Among patients with an admission hs-cTnT of <52 ng/L who were classified as high-risk patients when incorporating past hs-cTnT measurements, 28% suffered an MI.

Conclusions

Historical hs-cTnT levels can be used with admission hs-cTnT to improve early risk stratification of MI in the ED.

Published: August 2022

Objectives

For patients with a reduced left ventricular ejection fraction (LVEF) heart failure with reduced ejection fraction (HFrEF) and iron deficiency, administration of intravenous iron improves symptoms, exercise capacity and may in the following 12 months, reduce hospitalisations for heart failure. The Effectiveness ofIntravenous irontreatment versus standard care in patients with heart failure and iron deficiency (IRONMAN) trial evaluated whether the benefits of intravenous iron persist in the longer term and impact on morbidity and mortality.

Methods

IRONMAN is a prospective, randomised, open-label, blinded endpoint (PROBE) event-driven trial. Patients aged ≥18 years with HFrEF (LVEF ≤45%) and evidence of iron deficiency (ferritin <100 µg/L and/or TSAT <20%) were enrolled if they had either a current or recent hospitalisation for heart failure or elevated plasma concentrations of a natriuretic peptide. Participants were randomised to receive, or not to receive, intravenous ferric derisomaltose in addition to guideline-recommended therapy for HFrEF. Every 4 months, intravenous iron was administered if either ferritin was <100 µg/L or, provided ferritin was ≤400 µg/L, TSAT was <25%. The primary endpoint is a composite of total hospitalisations for heart failure and cardiovascular death. Hospitalisation and deaths due to infection are safety endpoints.

Results

Trial recruitment was completed across 70 UK hospital sites in October 2021. Participants were followed until the end of March 2022. We plan to report the results by November 2022.

Conclusions

IRONMAN will determine whether repeated doses of intravenous ferric derisomaltose are beneficial and safe for the long-term treatment of a broad range of patients with HFrEF and iron deficiency.

Shadows and thin accretion disk images of the $$\gamma $$-metric

γ

Authors: Jalali Mahdi , Fazeli Seyyed Poorya , Ebrahemzadih Mehrzad , Zakeri Hamid Reza , Rahimimoghadam Somayeh , Mojiri Samane Abd
Published: August 2022

Introduction: Carpet weaving is one of the most common occupations in Iran. Studies have shown that the majority of workers in these industries are women and these people are exposed to high occupational risks such as musculoskeletal disorders (MSDs). This study aimed to evaluate the hands activity level and upper extremity work-related musculoskeletal disorders (UEWMSDs) symptoms in female carpet weavers (FCWs).

Methods: This case-control observational study was performed on 150 FCWs of a carpet weaving workshop as a case group and 150 office staff as a control group. In order to assess the risk factors for UEWMSDs, the Hand Activity Level-Threshold Limit Value (HAL-TLV) method was used. The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was used to assess the prevalence of UEWMSDs symptoms in the past year. Data were analyzed using SPSS-V 24.

Results: The mean final scores of the HAL_TLV for the case and control groups were 1.04 and 0.15, respectively. The results of the statistical analysis showed a statistical significant difference between the mean of HAL, NPF, and HAL_TLV variables in case and control groups ([Formula: see text] [Formula: see text] 0.001). Also, the results showed a statistical significant difference between the mean scores of the incidence of discomfort in the Shoulder, Forearm, and Wrist areas in the case and control groups ([Formula: see text] [Formula: see text] 0.001).

Conclusion: The results of this study show the effect of increasing the level of hand activity on UEWMSDs symptoms. To reduce the level of hand activity and UEWMSDs symptoms in FCWs, there should be increased focus on work time, work speed, and the use of ergonomic, lightweight hand tools.
On the induced measure-theoretic entropy for random dynamical systems
Authors: Yang Kexiang , Chen Ercai , Zhou Xiaoyao
Published: August 2022

In this paper, we introduce the concepts of induced topological entropy and induced measure-theoretic entropy for random dynamical systems. By providing the topological version of induced measure-theoretic entropy, we establish the Katok entropy formula for a continuous bundle random dynamical system over an invertible ergodic system. We also consider the induced version with lower and upper pointwise dimensions, and establish a measure-theoretic entropy formula for lower and upper induced pointwise dimensions for a continuous bundle random dynamical system over an invertible ergodic system.
Multimodal Medical Image Fusion with Improved Multi-Objective Meta-Heuristic Algorithm with Fuzzy Entropy
Authors: Nagaraja Kumar N. , Jayachandra Prasad T. , Satya Prasad K.
Published: August 2022

Medical image fusion enhances the significant and the valuable information such as exact abnormality localisation of the multimodal medical images. In the field of clinical environment, medical imaging acts as an important role in helping the doctors/radiologists. The information available in the images is important during the diagnosis. This can be enhanced using the multimodal medical image fusion technique through the integration of the information from several imaging modalities. Nowadays, several methodologies are proposed for fusing the medical images. Yet, the multimodal medical image fusion remains as a challenging task owing to the deprivation of medical images at the phase of acquisition. To handle this problem, this paper plans to develop the enhanced multi-objective medical image fusion model. Before initiating the fusion process, both the images to be fused are split into high-frequency sub-bands and low-frequency sub-bands by the improved Fast Discrete Curvelet Transform (FDCuT). Here, the fusion of low-frequency sub-images is accomplished by the averaging method, and high-frequency sub-images are fused by the optimised Type-2 fuzzy entropy. Both the FDCuT and Type-2 fuzzy entropy are enhanced by the multi-objective meta-heuristic algorithm by Adaptive Electric fish optimisation (A-EFO). The multi-objective function focuses on the “Peak Signal to Noise Ratio (PSNR), Structural SIMilarity (SSIM), Feature SIMilarity (FSIM)”. The comparison of the developed methodology over the traditional approaches observes enhanced performance with respect to visual quality measures.

Published: August 2022

The physical design of a robot suggests expectations of that robot’s functionality for human users and collaborators. When those expectations align with the robot’s true capabilities, users are more likely to adopt the technologies for their intended use. However, the relationship between expectations and socially interactive robot design is not well understood. This article applies the concept of
design metaphors
to robot design and contributes the
Metaphors for Understanding Functional and Social Anticipated Affordances
dataset of 165 extant robots and the expectations users place on them. We used Mechanical Turk to crowd-source user expectation over three user studies. The first study (
N
= 382) associated crowd-sourced design metaphors to different robot embodiments. The second study (
N
= 803) assessed initial social expectations of robot embodiments. The final study (
N
= 805) addressed the degree of abstraction of the design metaphors and the functional expectations projected on robot embodiments. We performed analyses to gain insights into how design metaphors can be used to understand social and functional expectations of robots and how these data can be visualized to be useful for study designers and robot designers. Together, these results can serve to guide robot designers toward aligning user expectations with true robot capabilities, facilitating positive human–robot interaction.

Published: August 2022

By 2050, the world’s population will have increased by 34%, to more than 9 billion people, needing a 70% increase in food production. Prepare more dishes with fewer ingredients. Therefore, the critical goal of manufacturers is to increase production while being ecologically benign. Supply chain systems that do not enable direct farmer-to-consumer connection and rising input costs influence data collection, security, and sharing. Constraints on data security, manipulation, and single-point failure are unfulfilled due to a lack of centralized IoT agricultural infrastructure. To address these issues, the article proposes a blockchain-based IoT model. This study also shows one-of-a-kind energy savings. The decentralization of data storage improves the supply chain’s transparency and quality through blockchain technology, thus farmers can engage more efficiently. Blockchain technology improves supply chain traceability and security. This article provides a transparent, decentralized blockchain tracking solution and proposes an intelligent model protocol for several Internet of Things (IoT) devices that monitor crop development and the agricultural environment. A new approach has resolved the bulk of the supply chain difficulties. Smart contracts were utilized to organize all transactions in decentralized supply networks. The use of blockchain technology improves transaction quality, and customers may verify the legitimacy of an item’s authenticity and legality by using the system. A total of 100 IoT nodes were distributed randomly to each 500 m2 cluster farm. The Internet of Things nodes were used to assess soil moisture, temperature, and crop disease. Network stability period and network life of the proposed method show 90.4% accuracy. The food supply chain will be more efficient and trustworthy with an intelligent model. The immutability of ledger technology and smart contract support further increases supply chain security, privacy, transparency, and trust among all stakeholders in the multi-party system. By 2050, the world’s population will need a 70% increase in food production. The food supply chain will be more efficient and trustworthy with an intelligent model. This article provides a transparent, decentralized, and intelligent model protocol for several Internet of Things (IoT) devices.
Neural Network Model for Perceptual Evaluation of Product Modelling Design Based on Multimodal Image Recognition
Authors: Wu Jie , Jia Long
Published: August 2022

With the homogenization of product function and performance, the design technology for product appearance quality has been increasingly valued by academia and industry and has become an effective technical way to meet the continuously growing diversified and personalized needs of consumers. The appearance quality attribute of a product can be characterized or described by its appearance image. Data-driven product appearance image design is based on the quantitative data of product appearance and consumer emotional needs and completes the product appearance through computer-aided design technology and intelligent algorithms. Design innovation can help companies quickly respond to consumers’ emotional needs and effectively improve design quality and product competitiveness. When visual objects are disturbed in complex scenes, the issues such as how the human brain coordinates multisensory information processing and what neural processing mechanisms follow are still unclear. In this paper, a visual object recognition experiment in a complex scene was designed and the brain activation signals of three modalities of noise, added audio-visual (AVd), single visual noise and noise (Vd), and single-audio (A), were recorded. The properties and neural processing mechanisms of multisensory modulation of auditory stimuli during noisy image recognition were explored. Using the conjunction method combined with the classic “max criterion” rule, it was found that only when a certain amount of noise was added to the visual stimulus, the integration area changed. The product appearance has a decisive influence on the user’s product perceptual attribute preference and greatly affects the consumer’s satisfaction. The importance of product appearance image design is increasingly prominent. In addition, pattern analysis of brain activation signals confirmed that semantically consistent sounds can facilitate the recognition of noisy images and this facilitation shows a certain category selectivity when subdivided into categories. Using the analysis method of functional connectivity, a functional connectivity network containing nodes at different integration levels was constructed to explore the overall characteristics and processing patterns of the multisensory network. Through the analysis of the network connection relationship, it is found that the prefrontal cortex, STS, and lateral occipital lobe are the nodes with more aggregation in the network, and their functions are similar to the hub in the network. The brain functional network was constructed, and functional connectivity was used to explore the connection characteristics of the network and the multisensory modulation mechanism between different processing levels of the brain.

This research explored the effects of the COVID-19 pandemic on increasing the unemployment anxiety levels of graduate students at Prince Sattam Bin Abdulaziz University. To fulfill the objective of this study, 120 graduate students at the mentioned university were selected based on the convenience sampling method as the participants of the study. Sixty participants lost their jobs during the Coronavirus 2019 pandemic, but the rest had jobs. After determining the participants’ job conditions, the researchers administered Zung’s (1971) anxiety questionnaire via e-mail, Telegram, WhatsApp, Microsoft Teams, Zoom, WeChat, Google Meetings, and other social media platforms. One hundred and seven students (56 employed and 51 unemployed) completed the questionnaire and sent it back to the researchers. The parametric results divulged a notable difference between the anxiety level of the employed and unemployed groups, implying that the unemployed participants had much more anxiety during the Coronavirus 2019 pandemic. The implications of this research can be compelling for governments to take practical actions during fatal disasters such as the COVID-19 pandemic.

Nutrients in quail eggs can be affected by egg product processing technologies. However, freeze-drying would be the most suitable, but it is very costly and difficult to transfer to the quail egg production actors. This study is aimed at comparing the physicochemical and microbiological qualities of liquid, pasteurized, hot air-dried, and freeze-dried quail eggs. Liquid quail eggs were used as controls. The physicochemical and microbiological qualities were evaluated by conventional methods. The results showed that freeze-dried and hot air-dried quail eggs differed (

p
<
0.05

) from liquid and pasteurized quail eggs for all the evaluated parameters. On the other hand, pasteurized quail eggs were more concentrated (

p
<
0.05

) in dry matter (

%

) and fat (

25.8

) with a more basic pH (

) than liquid eggs. As for microbiological parameters, only total mesophilic aerobic germs were present with a significant difference (

p
<

log10 CFU/g), hot air-dried (

2.1
±

log10 CFU/g), and freeze-dried (

1.8
±

log10 CFU/g) quail eggs, but the load was much lower than the standard (5.7 log10 CFU/g). Total coliforms (0 CFU/g), Enterobacteriaceae (0 CFU/g), yeasts (0 CFU/g), molds (0 CFU/g), Salmonella, and Staphylococcus aureus were absent in all the egg products, while the standards provided 2.0 log10 CFU/g for total coliforms, 1.0 log10 CFU/g for Enterobacteriaceae, Salmonella absent in 25 g, Staphylococcus aureus absent in 1 g, and 2.0 log10 CFU/g for yeasts and molds. In conclusion, hot air-drying and pasteurization are transferable and suitable for the processing of quail eggs.

Published: August 2022

Movement object detection method is the basis and key of the modem intelligent video surveillance system. It combines advanced technologies in many fields, such as artificial intelligence, image processing, and pattern recognition, and is the research area of computer vision technology. Therefore, it is important to explore the motion detection and target recognition algorithms. The data collection method has concluded that T > 60 is absent from four different videos. The T value is traversed from 0–255 to select the largest T value as the split threshold. Through the analysis, the range of the threshold selection can be reduced to 0-60, thus improving the operational efficiency.

Authors: Chen Wenru , Yu Xiaoqing
Published: August 2022

Objective. To evaluate the diagnostic value of combined detection of color Doppler flow imaging (CDFI) and serum C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6) levels for neonatal pneumonia. Methods. In this prospective study, 30 newborns with pneumonia and 30 healthy newborns in our hospital from January 2019 to January 2020 were recruited. The healthy newborns were assigned to the control group, and the newborns with pneumonia were assigned to the experimental group. All subjects underwent CDFI and measurement of the levels of serum CRP, PCT, and IL-6. The serum indices and imaging results of the two groups were analyzed, and the specificity and sensitivity of different detection methods in the diagnosis of neonatal pneumonia were calculated and analyzed. Results. The levels of serum CRP, PCT, and IL-6 in the experimental group were significantly higher than those in the control group (

P
<
0.001

). Combined detection had a larger detection area, higher sensitivity, and a superior overall detection outcome than single detection (

P
<
0.05

). The diagnostic results of combined detection and clinical diagnosis in 30 newborns with pneumonia were similar (

P
>
0.05

). Conclusion. The combined detection of CDFI and serum CRP, PCT, and IL-6 levels in the diagnosis of neonatal pneumonia shows a promising diagnostic outcome, so it is worthy of clinical application.

For children, school-age is the best time to develop common-sense knowledge, as they need to know things by touch and direct perception. Currently, fire productions for children are the best medium for children’s learning but most of the existing children’s firefighting products have a single function and low interest, which cannot meet the growing needs of children and gradually cannot attract children’s attention. In terms of user experience, Augmented Reality (AR), as a new technology, is easy to arouse children’s interest in learning and stimulate children’s curiosity and exploration. AR technology adds computer-generated writing information, pictures, virtual 3D designs, videos, or scenes to the actual background perceived by users in real-time and accurately. It recognizes the organic incorporation of virtual and real scenes, to achieve a sensory practice outside reality. Integrating this technology into the design of children’s fire education products will play a role in teaching fun. Keeping the importance of VR technology in our society, this research paper designs a smart car by utilizing STM32F103 chip microcontroller as the key regulator core to regulator peripheral motorized drives, ultrasound, sensors, and other modules. Furthermore, the experiments demonstrate that the laboratory may be of practical benefit in developing learners’ comprehensive capacity and practical technological capabilities.

Published: August 2022

Background. T-cell malignancies (TCMs), including T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoma (TCL), are highly aggressive and have a poor prognosis. To further understand prognostic stratifications and to design targeted therapies, this study aims to explore novel, potential biomarkers based on alterations in immune costimulatory molecules (CMs) for TCMs. Methods. Peripheral blood from 25 de novo T-ALL patients in our clinical center and transcriptome data from 131 to 162 patients with peripheral TCL (PTCL) from the GSE19069 and GSE58445 dataset, respectively, were obtained to assess the expression levels of CMs and their prognostic significance. Results. Seven CMs were associated with overall survival (OS). Among these CMs, CD5 and CD6 had the highest pairwise positive correlation (R = 0.69). CD5 and CD6 were significantly down-regulated in TCM patients compared with healthy individuals (HIs), and lower CD5 and CD6 expression was associated with poor OS for both T-ALL and TCL patients, particularly for patients greater than 60 years old. Furthermore, CD5 was positively correlated with CD6 in TCM patients. Compared with patients who were CD5highCD6high, T-ALL and TCL patients who were CD5lowCD6low had poor OS. Importantly, CD5highCD6high was an independent prognostic predictor for OS in T-ALL (HR = 0.39, 95% CI: 0.23–0.65,P<0.001) and TCL (HR = 0.35, 95% CI: 0.19–0.62,P<0.001) patients. Conclusions. Low expression of CD5 and CD6 was associated with poor OS for TCM patients, and this may be a potential immune biomarker panel for prognostic stratification of TCM patients.
MULTIMOORA Method for Addressing Security Algorithms Evaluation Problem under q-Rung Orthopair Fuzzy Environment
Authors: Wang Rongguo , Li Xinmei , Lin Mingwei , Lin Zhanpeng
Published: August 2022

How to determine a suitable security algorithm for a special application scenario is a complex problem. In this paper, this complex problem is formulated as a multicriteria decision-making (MCDM) problem, and we propose a novel MULTIMOORA (multiobjective optimization on the basis of a ratio analysis plus the full MULTIpevaluation information in the security algorithms evaluation problem. The MULTIMOORA method is an excellent decision method, which owns strong robustness. However, it has not been used to process the complex information structure of q-rung orthopair fuzzy sets. Moreover, it cannot solve the problem that the extreme values negatively influence the ranking results, and it also cannot capture the interrelationship hiding behind the criteria. To overcome the above challenges, we propose novel q-rung orthopair fuzzy Dombi power Heronian mean (DPHM) operator and q-rung orthopair fuzzy Dombi power geometric Heronian mean (DPGHM) operator. Based on these two operators, the MULTIMOORA method is improved for solving the security algorithms’ evaluation problem. Finally, a practical example for evaluating five security algorithms is used to illustrate the decision process of the proposed q-rung orthopair fuzzy MULTIMOORA method.

Published: August 2022

This work aims to optimize and innovate the protection, inheritance, and dissemination of Intangible Cultural Heritage (ICH). Based on the Internet of Things (IoT), this work designs the music ICH development path under the cultural concept by integrating music ICH with the tourism industry in the smart city environment. Specifically, it innovatively proposes the integration mechanism of immersive scene design of music ICH with smart city’s tourism industry in the Internet of Things (IoT) context. Consequently, the music ICH brand equity evaluation model is built. This model can evaluate the importance of cultural and asset value of music ICH. The comprehensive evaluation index system of music ICH mainly includes four primary indexes (with eight secondary indexes): the live performance, historical value, music audience, and the tourism industry integration. In addition, at the beginning of the model iteration, the pattern recognition accuracy of the traditional model is only 67.5%. Then, the recognition accuracy of the traditional model can reach 72.5% at the 500th iteration. In contrast, the average recognition accuracy of the improved model can reach 80%, and the highest can reach 82.5%. This work can provide technical support and guarantee for formulating and optimizing music ICH protection strategies.

The optimization path of art teaching methods in universities cannot balance the contradiction and conflict between cost and benefit, which affects the educational efficiency. This paper proposes an optimization path method for art teaching methods in universities based on a multiuniverse algorithm. According to the relationship between teachers, students, and teaching materials, build an efficient art teaching knowledge dissemination model, extract the characteristics of art teaching innovation path, and make decisions on costs and benefits. Establish the art teaching path selection model based on the multiuniverse algorithm, give full play to the leading role of the university organization system through path design, and meet the personalized teaching and learning needs of teachers and students by designing the cost and cost objective function under the optimal benefit of art teaching. Using dance as an example, the art teaching path optimization approach based on a multiuniverse algorithm has an education efficiency of 1.476, which is 0.593 and 0.607 greater than the methods based on association rule and clustering algorithms. As a result, this strategy can improve the quality of art instruction while also facilitating reform and innovation in the classroom.
