Variation in Bioactive Compounds and Antioxidant Activity of Rubus Fruits at Different Developmental Stages

Blackberry and raspberry have high nutritional, health value, and are popular with consumers for their unique flavors. To explore the relationships between nutrient accumulation, antioxidant substance contents in blackberry and raspberry fruits, and fruit growth and development, seven Rubus cultivars were selected, and contents of the main active substance were determined. “Clode Summit” had the highest soluble sugar and fructose contents, “Chester”—the highest total phenol content, and “Bristol’—the highest anthocyanin content. Generally, the contents of flavonoids and total phenols showed a downward trend with the development of fruit in seven Rubus cultivars, and the content of anthocyanins increased rapidly in the later stage of development. Pearson correlation analysis showed extremely significant correlation between antioxidant activity and the contents of vitamin E, total phenols, and flavonoids. Flavonoids were extremely significantly positively correlated with the content of total phenols, and the contents of flavonoids and anthocyanins in various cultivars were highly negatively correlated. Considering the different nutritional ingredients and active antioxidant substance contents, “Clode Summit”, “Bristol”, and “Chester” are recommended for raw consumption, processing, and medicinal purposes, respectively. These results provide a reference for comparing the main active substance contents in different Rubus cultivars and their changes across fruit development stages.

Temporal and Spatial Patterns of Sediment Microbial Communities and Driving Environment Variables in a Shallow Temperate Mountain River

Microbial communities in sediment play an important role in the circulation of nutrients in aquatic ecosystems. In this study, the main environmental factors and sediment microbial communities were investigated bimonthly from August 2018 to June 2020 at River Taizicheng, a shallow temperate mountain river at the core area of the 2022 Winter Olympics. Microbial community structure was analyzed using 16S rRNA genes (bacteria 16S V3 + V4 and archaea 16S V4 + V5) and high-throughput sequencing technologies. Structure equation model (SEM) and canonical correspondence analysis (CCA) were used to explore the driving environmental factors of the microbial community. Our results showed that the diversity indices of the microbial community were positively influenced by sediment nutrients but negatively affected by water nutrients. Bacteroidetes and Proteobacteria were the most dominant phyla. The best-fitted SEM model indicated that environmental variables not only affected community abundance directly, but also indirectly through influencing their diversity. Flavobacterium, Arenimonas and Terrimonas were the dominant genera as a result of enriched nutrients. The microbial community had high spatial–temporal autocorrelation. CCA showed that DO, WT and various forms of phosphorus were the main variables affecting the temporal and spatial patterns of the microbial community in the river. The results will be helpful in understanding the driving factors of microbial communities in temperate monsoon areas.
Long-term hydrothermal Scheduling with aggregate and individual Reservoirs

This thesis is a comparative analysis of two commensurable models used in long-term hydrothermal scheduling. The first model is the EMPS model, which is the most prevalent tool for long-term planning in the Norwegian power industry. The second model is known as the SOVN model, which is currently under development at SINTEF Energy Research. A tighter market coupling to the continental European power system with an increasing penetration of intermittent and non-storable renewable energy, requires models that better represent the flexibility of the Nordic hydropower system, since the reservoir aggregation of the EMPS model has proven inadequate to fully handle this. SOVN aims to circumvent this through a detailed simulation of the hydropower system, where the production at each individual power plant is optimized through a complex SLP algorithm using Benders decomposition. Moreover, the SOVN model does not require the same substantial user input as EMPS, which can help minimizing some of the uncertainty of the results. The first part of this thesis covers the Nordic hydropower system, power system economics and the general framework for long-term hydrothermal scheduling. In the two subsequent chapters the EMPS and SOVN models are thoroughly introduced, both conceptually and mathematically. The analytical part of this thesis is initiated with a review of the case scenarios and power system data: The analysis addresses a confined power system in Northern Norway, where adjacent markets are represented as exogenous price files. The first part of the analysis examines the influence on the performance of SOVN by changing the settings in the SOVN.ctrl file. The remaining analysis investigates the power system in extreme surplus situations, by introducing increased wind power development in the region, given as discrete scenarios between 265 and 4,835 MW installed capacity. In the most moderate of these cases, the share of unregulated production, i.e. production with zero opportunity cost, in EMPS and SOVN is 28.71% and 7.81%, respectively. With 4,835 MW installed wind energy these shares are increased to 44.06% and 9.28%. That is, not only does SOVN minimize its forced production, it also reduces the impact of surplus situations on its operational liberty. Consequently, spillage in SOVN is also significantly reduced: The total percentage of spillage to optional production in the three southernmost subareas, is more than 6% in EMPS and approximately 1% in SOVN. Power surplus results in lower wholesale prices for both models, and bottlenecks in the grid evoke price gaps between adjacent market. In the most extreme case, SOVN reduces the mean price gap with 3.04e/MWh
Effect of R&D Subsidies on External Collaborative Networks and the Sustainable Innovation Performance of Strategic Emerging Enterprises: Evidence from China

Building external collaboration networks is key to the sustainable innovation performance of strategic emerging industries (SEIs) in the context of open innovation. R&D subsidy policies in China are typically designed to support R&D investment, though the question remains whether this policy tool can stimulate sustainable innovation performance by building external collaborative networks for enterprises. At present, few studies discuss the behavioral additionality of subsidies in the context of emerging economies, and relevant studies are mainly conducted from the single perspective of input additionality. This paper integrates the input, output, and behavioral additionality of R&D subsidies into the same framework and investigates the relationships among R&D subsidies, external collaborative networks, R&D investment, and the sustainable innovation performance of strategic emerging enterprises (SEEs) among Chinese SEIs listed enterprises in 2010–2019, mainly using the panel fixed effects regression model. The results show that R&D subsidies in China promote sustainable innovation performance and that this effect is mediated by external collaborative networks and R&D investment. Additionally, R&D subsidies negatively moderate the indirect effect of external collaborative networks on sustainable innovation performance, and the moderating effects of R&D subsidies under heterogeneous samples differ in sign, statistical significance, and impact magnitude. Based on the conclusions, policy-makers must comprehensively consider the multiple effects of R&D subsidies, develop more sophisticated policy tools for network coordination, and implement differentiated subsidy policies to align with open innovation in the future.
Factors Affecting Psychological and Health-Related Quality-of-Life Status in Children and Adolescents with Congenital Heart Diseases

Congenital heart disease (CHD), a severe cardiac defect in children, has unclear influences on young patients. We aimed to find the impacts of differently structure heart defects and various treatments on psychology and health-related quality of life (HRQoL) in CHD children and adolescents. CHD patients aged between 6 and 18 years old visited our hospital from 1 May 2018 to 31 September 2018, and their principal caregivers were asked to participate. We used two validated questionnaires, Children Depression Inventory-TW (CDI-TW) and Child Health Questionnaire—Parent Form 50 (CHQ-PF 50), to evaluate CHD patients’ psychological and HRQoL conditions. Participants were grouped based on their cardiac defects and previous treatments. We analyzed the results via summary independent-samples t-test with post hoc Bonferroni correction and multivariant analysis. Two hundred and seventy-seven children and their principal caregivers were involved. There was no apparent depressive condition in any group. Single cardiac defect patients exhibited similar HRQoL to controls; simultaneously, those with cyanotic heart disease (CyHD), most multiple/complex CHDs children and adolescents, and those who received invasive treatments had poorer HRQoL. CyHD impacted the most on patients’ psychological and HRQoL status. Patients with sole cardiac defect could live near-normal lifes; on the other hand, CyHD had the worst effects on patients’ psychology and HRQoL.
Methodology for Measuring the Frequency Dependence of Multipath Channels Across the Millimeter-Wave Spectrum

Millimeter-wave (mmWave) communications promise Gigabit/s data rates thanks to the availability of large swaths of bandwidth between 10–100 GHz. Although cellular operators prefer the lower portions of the spectrum due to popular belief that propagation there is more favorable, the measurement campaigns to confirm this – conducted by ten organizations thus far – report conflicting results. Yet it is not clear whether the conflict can be attributed to the channel itself – measured in different environments and at different center frequencies – or to the differences in the organizations’ channel sounders and sounding techniques. In this paper, we propose a methodology to measure mmWave frequency dependence, using the 26.5–40 GHz band as an example. The methodology emphasizes calibration of the equipment so that the measurement results represent the channel alone (and not the channel coupled with the channel sounder). Our results confirm that free-space propagation is indeed frequency invariant – a well understood phenomena but to our knowledge reported nowhere else at mmWave to date. More interestingly, we found that specular paths – the strongest after the line-of-sight path and so pivotal to maintaining connectivity during blockage – are the least invariant compared to weaker diffracted and diffuse paths.
Analysis of the Active Measurement Systems of the Thoracic Range of Movements of the Spine: A Systematic Review and a Meta-Analysis

(1) Objective: to analyze current active noninvasive measurement systems of the thoracic range of movements of the spine. (2) Methods: A systematic review and meta-analysis were performed that included observational or clinical trial studies published in English or Spanish, whose subjects were healthy human males or females ≥18 years of age with reported measurements of thoracic range of motion measured with an active system in either flexion, extension, lateral bending, or axial rotation. All studies that passed the screening had a low risk of bias and good methodological results, according to the PEDro and MINORS scales. The mean values and 95% confidence interval of the reported measures were calculated for different types of device groups. To calculate the differences between the type of device measures, studies were pooled for different types of device groups using Review Manager software. (3) Results: 48 studies were included in the review; all had scores higher than 7.5 over 10 on the PEDro and MINORs methodological rating scales, collecting a total of 2365 healthy subjects, 1053 males and 1312 females; they were 39.24 ± 20.64 years old and had 24.44 ± 3.81 kg/m2 body mass indexes on average. We summarized and analyzed a total of 11,892 measurements: 1298 of flexoextension, 1394 of flexion, 1021 of extension, 491 of side-to-side lateral flexion, 637 of right lateral flexion, 607 of left lateral flexion, 2170 of side-to-side rotation, 2152 of right rotation and 2122 of left rotation. (4) Conclusions: All collected and analyzed measurements of physiological movements of the dorsal spine had very disparate results from each other, the cause of the reason for such analysis is that the measurement protocols of the different types of measurement tools used in these measurements are different and cause measurement biases. To solve this, it is proposed to establish a standardized measurement protocol for all tools.
A Review of the Relationship between Heart Rate Monitoring, Training Load, and Injury in Field-Based Team Sport Athletes

Outdoor, field-based team sports have been a staple of American and international cultures throughout recorded history and are currently played by millions of athletes around the globe. In modern competition, it is critical for athletes and support staff such as coaches, strength and conditioning specialists, and medical personnel to cooperate to optimize competitive readiness and performance. Important variables that can enhance or reduce physiological adaptations related to these areas include the relationship between the prescribed training workload and potential injuries. Therefore, it is important to understand and modify these aspects to fit the unique needs of individual athletes and specific teams. Recent advancements in technology now allow aspects of performance to be monitored in real time via methods that are reliable, cost effective, and noninvasive. The purpose of this literature review is to summarize and elucidate the available information on the potential relationship between heart rate monitoring and training load and how it may be used to prevent, predict, or detect an injury among athletes who participate in field-based sports. Overall, results indicate that while such technology has been used to describe and prescribe training workload, little research has been done to monitor the relationship between these variables and proclivity for or recovery from injury. Future longitudinal studies that encapsulate and address the highly dynamic nature and relationship of these variables are needed to better understand how they interact. Such an understanding may allow personnel such as coaches and staff to better support athletes on and off the field.
LC Passive Wireless Sensor System Based on Two Switches for Detection of Triple Parameters

This paper presents the LC-type passive wireless sensing system for the simultaneous and independent detection of triple parameters, featuring three different capacitive sensors controlled by two mechanical switches. The sensor coil was connected with three different capacitors in parallel and two mechanical switches were in series between every two capacitors, which made the whole system have three resonant frequencies. The readout coil was magnetically coupled with the sensor coil to interrogate the sensor wirelessly. The circuit was simulated advanced design system (ADS) software, and the LC sensor system was mathematically analyzed by MATLAB. Results showed that the proposed LC sensing system could test three different capacitive sensors by detecting three different resonant frequencies. The sensitivity of sensors could be determined by the capacitance calculated from the detected resonant frequencies, and the resolution of capacitance was 0.1 PF and 0.2 PF when using the proposed sensor system in practical applications. To validate the proposed scheme, a PCB inductor and three variable capacitors were constructed with two mechanical switches to realize the desired system. Experimental results closely verified the simulation outputs.
Multi-Scale Influence of Flexible Submerged Aquatic Vegetation (SAV) on Estuarine Hydrodynamics

Bottom friction is an important process in coastal and estuarine environments because it can reduce wave heights and moderate tidal currents. When modeling large systems with spatially varying hydraulic properties, bottom friction values are commonly derived from land use classification products. However, estimation of bottom friction for vegetated areas can be more challenging due to the complicated and time-varying geometry of the roughness elements. This is particularly true of flexible, buoyant submerged aquatic vegetation (SAV) species, such as seagrasses and kelps, that deform under waves and currents. In this study we incorporate a dynamic friction model that includes the temporal variation in SAV drag forces into a depth-integrated coupled circulation-wave model. In vegetated areas, the bottom friction is continuously updated based on plant geometry, water depth, and combined wave-current velocities. Taking a multi-scale approach, we use the model to investigate the impact of SAV dynamics on both the localized and the integrated bay-wide hydrodynamics of a riverine and tidally influenced estuary. First, we investigate SAV modification of velocity fields and its implications for sediment transport and circulation pathways. Then, we show how SAV can modify tidal behavior throughout the estuary.
Contemporary review of stock market liquidity studies in emerging countries

This study presents a review of stock market liquidity in emerging countries. Specifically, it highlights the factors that lead to the occurrence of a liquid market in emerging countries. Following a study by Ding, Ni, and Zhong (2016), this study argues that firms are motivated to have liquid stock to enable them to raise funds at a lower cost, so as to exploit growth opportunities. This paper contributes additional knowledge in terms of understanding stock market liquidity and offers some suggestions for future research. A systematic literature review (SLR) was adopted on stock market liquidity and its related causes and effects, encompassing the years 2010 to 2021. Based on the SLR, it is noted that the features and practices of firms, as well as the policies and regulations that are imposed by regulatory bodies and governments in emerging countries, are important. The limitation of this study is that only four micro-environmental factors and two macro-economic factors were reviewed. Therefore, it is suggested that in the future, researchers should focus on other factors, such as financial performance and political connection. The identification of factors in this study highlighted the gaps in current practices, thus, motivating future research to scrutinise issues relating to stock market liquidity more intensively
Efficacy of Vernonia cinerea (L) Less for smoking cessation: An updated meta-analysis of randomized controlled trials

Vernonia cinerea (VC) has been used for smoking cessation. A previous meta-analysis (MA) reported the efficacy of VC in smoking cessation. However, there have been updated randomized controlled trials (RCTs) on the efficacy of VC for smoking cessation, and the previous MA lacked pooled adverse events (AEs) related to VC. The objective of this study was to systematically review and perform an updated MA on the efficacy of VC for smoking cessation continuous abstinence rate (CAR), prevalence abstinence (PAR), and AE. The research articles were retrieved via electronic databases including PubMed, Science Direct, Web of Science, Thai-Journal Citation Index Center (TCI), and ThaiLis. Ten RCTs published prior to 2019 were included in this study. The number of participants in the studies ranged from 35 to 172, and the follow-up duration for the primary outcomes was 2-12 weeks. Our updated MA found that VC could significantly improve CAR2 (RR=1.54; 95% CI = 1.06, 2.23), CAR4 (RR=1.65; 95% CI = 1.25, 2.17), CAR 8 (RR=1.85; 95% CI = 1.25, 2.75), CAR12 (RR=2.56; 95% CI = 1.66, 3.95), and CAR16 (RR=2.21; 95% CI = 1.03, 4.73). Moreover, VC improved PAR2 (RR=1.47; 95% CI = 1.06, 2.04), PAR4 (RR=1.35; 95% CI = 1.02, 1.79), PAR8 (RR=1.60; 95% CI = 1.11, 2.31), and PAR12 (RR=1.70; 95% CI = 1.25, 2.30). There was no significant difference in the AE between the two groups. The study substantiates claims that VC products are effective in assisting with smoking cessation.
Influence of Formulation Factors, Process Parameters, and Selected Quality Attributes on Carvedilol Release from Roller-Compacted Hypromellose-Based Matrix Tablets

The importance of roller compaction is recently increasing. This study evaluates the combined effects of formulation factors, process parameters, and selected quality attributes on drug release from roller-compacted hypromellose-based matrix tablets containing carvedilol as a model drug. The influence of selected factors was statistically assessed and good predictive models were developed for various time points of the release profile. The results show that the release profile is mostly affected by the particle size distribution of granules and roll speed. This indicates that the roller compaction process has a major impact on drug release, which is also formulation dependent. A higher d50 and lower d90 value of spatial filtering technique-based particle size distribution results, a lower roll speed, increased hypromellose content, using microcrystalline cellulose as a filler, and higher tablet hardness, resulted in a decrease in the drug release rate. On the other hand, the effect of the roll pressure, size of screen apertures, and d10 values on drug release was insignificant. The significance of the factors was further explained by granule shape, their porosity, and friability evaluation, and by compressibility and compactibility studies of compression mixtures. Additionally, the spatial filtering technique demonstrated to be a promising tool in controlling the roller compaction process.
