Smart Operation Control of Power and Heat Demands in Active Distribution Grids Leveraging Energy Flexibility
Authors: Sinha Rakesh , Chaydhary Sanjay , BAK-JENSEN Birgitte , Golmohamadi Hessam
Published: May 2024

Demand flexibility plays a crucial role in mitigating the intermittency of renewable power sources. This paper focuses on an active distribution grid that incorporates flexible heat and electric demands, specifically Heat Pumps (HPs) and Electric Vehicles (EVs). Additionally, it addresses Photovoltaic (PV) power generation facilities and electrical batteries to enhance demand flexibility. To exploit demand flexibility from both heat and electric demand, along with the integration of PVs and batteries, Control and Communication Mechanisms (CCMs) are formulated. These CCMs integrate demand flexibility into the distribution grids to get economic benefits for private households and at the same time facilitate voltage control. Concerning EVs, the paper discusses voltage-based droop control, scheduled charging, priority charging, and up-/down-power regulation to optimize the charging and discharging operations. For heat demands, the on-off operation of the HPs integrated with Phase Change Material (PCM) storage is optimized to unlock heat-to-power flexibility. The HP controllers aim to ensure as much self-consumption as possible and provide voltage support for the distribution grid while ensuring the thermal comfort of residents. Finally, the developed CCMs are implemented on a small and representative community of active distribution grid with 8 houses using Power Factory software and DigSILENT Simulation Language (DSL). This scalable size of the active distribution network facilitates to carefully study symbiotic interaction among the flexible load, generation, and different houses thoroughly. The simulation results confirm that the integration of flexible demands into the grid using the designed CCMs results in the grid benefiting from stabilized voltage control, especially during peak demand hours.

Stunting is a prolonged state of chronic malnutrition. This disorder is characterized by having a body length-for-age or body height-for-age measurement that falls below the -2 standard deviation established by the World Health Organization (WHO). The etiology of stunting is multifaceted, encompassing factors such as nutrition, feeding practices, infectious illnesses, and household income. Maternal understanding of nutrition, including dietary factors, is also associated with the occurrence of stunting. This study aimed to establish the relationship between feeding habits and maternal knowledge of nutrition with the prevalence of stunting in the operational region of the Gedongan Health Center, located in Mojokerto City. This study is an observational analytical study employing a cross-sectional design. The study’s population consisted of all women with children residing in the working area of the Gedongan Health Center. This study encompassed 144 participants who completed the Child Feeding Questionnaire (CFQ) regarding eating practices and a questionnaire assessing maternal knowledge of nutrition. The objective was to examine the relationship between these factors to height and age. The chi-square test results indicate a statistically significant association between feeding practices and stunting (p = 0.0001) and maternal knowledge about nutrition and stunting (p = 0.0001). The survey revealed that most children had been provided with appropriate feeding patterns, and most moms had a commendable nutritional understanding. The study’s findings indicate a noteworthy relationship between feeding behaviors and mothers’ nutrition knowledge.

Acute respiratory distress syndrome (ARDS) poses a significant health risk due to long-term exposure to carbon monoxide-containing kitchen fumes. Installation of a cooker hood or kitchen smoke extractor with an automated fan is crucial for prevention. This study employed a research and development approach to evaluate the effectiveness of utilizing the NodeMCU ESP8266, MQ-7 sensor, 16x2 I2C LCD, and overall system configuration. Experimental results revealed the MQ-7 sensor's rapid response to smoke intensity changes, with an average 3.77-second response time and a range of detection up to 10cm. Relay testing for fan speed control, using three voltage inputs (5V, 9V, and 12V), categorized conditions as SLOW (PPM>10), MED (PPM <11 & >20), and HIGH (PPM>21). The tests demonstrated optimal performance, as the system successfully adjusted fan speeds based on varying smoke intensity levels, ensuring a healthy air quality environment.
Seismo-Tectonics, Crustal Velocity Structure and Moho Depth beneath the Dharwar Craton, India
Authors: Ande Ravi , Hazari Mousumi
Published: May 2024

The cross-correlation of continuous ambient noise data gathered from 35 broad-band seismographs over 18 months (February 2019 to August 2021), we produce Rayleigh-wave group velocity maps in the 5–28 s range. We supplement this with longer period data (40–70 s) from the earthquake source. Combining combined group velocity measurements with the tele-seismic receiver functions gathered at 50 stations—15 of which were operational from 1998 to 2012—was necessary to construct a shear velocity image of the crust. The crustal thickness of the late Archean (2.7 Ga) Eastern Dharwar Craton (EDC) is 34–38 km, but the crustal thickness of the mid-Archean and Proterozoic terrains is 40–50 km. The Western Dharwar Craton (WDC) is located 50 km away in the mid-Archean (3.36 Ga) greenstone region, which has the thickest crust. The average crustal velocity beneath the EDC is 3.70–3.78 km s-1, while the Moho depth and average crust velocity beneath the WDC are 3.80–3.95 km s-1. The thickness (Vs 3.8-4.2 km s1) of the lower crust varies significantly lateral, ranging from 10-15 km in the EDC to 20-30 km in the WDC. The lowest part of the crust (Vs 4.0 km s1) is thin (5 km) beneath the EDC, in contrast to the WDC, where the crust is thicker (10–27 km). We anticipate an intermediately composed crust beneath the EDC, akin to those of other cratons. The exposed WDC crust from the mid-Archean exhibits an unusual thickness and a greater mafic composition, in contrast to worldwide observations. We interpret this significant mafic crust as an undeformed geological section dating to 3.36 Ga. The EDC's very flat Moho, felsic to intermediate crust composition, and thin basal layer suggest that it was a reworked terrain during the late Archean.

Precipitation is an important factor influencing the date of leaf senescence (DFS), which in turn affects carbon uptake of terrestrial ecosystems. However, the temporal patterns of precipitation frequency (Pfreq) and its impact on DFS remain largely unknown. Using both long-term carbon flux data and satellite observation of DFS across the Northern Hemisphere, here we show that, after excluding impacts from of temperature, radiation and total precipitation, declining Pfreq drives earlier DFS from 1982 to 2022. A decrease in Pfreq intensified drought stress by reducing root-zone soil moisture and increasing atmospheric dryness, and limit the photosynthesis necessary for sustained growth. The enhanced drought acclimation also explained the positive Pfreq-DFS relationship. We found plants experiencing decreased Pfreq showed a more rapid response to drought, as represented by a shorter drought response lag, a measure of the time between a drought event and the most severe reduction in vegetation growth. In particular, increased evapotranspiration with shorter drought response lag was observed, further implying an enhanced water acquisition strategy representing drought acclimation as showing in strengthening roots system to deeper water resources. Finally, we found 30 current state-of-art Earth system models largely failed to capture the sensitivity of DFS to changes in Pfreq and incorrectly predicted the direction of correlations for approximately half of the northern global lands, in both historical simulations and future predictions under various shared socioeconomic pathways (SSPs). Our results therefore highlight the critical need to include precipitation frequency, rather than just total precipitation, into models to accurately forecast plant phenology under future climate change.

Published: May 2024

The magnitude of benefit of Mediterranean diet in cancer prevention and mortality in older adults is still unclear, therefore we conducted a systematic review and meta-analysis. Outcomes considered were cancer incidence and cancer mortality. In studies evaluating cancer incidence as a time-to-event endpoint and adherence as quantiles, HR was 0.885 (95% CI 0.773–1.013, I2 = 44%). Including ORs, exploratory pooled effect size was 0.876 (0.794–0.966, I2 = 34%), consistently with results of studies evaluating ORs for adherence as one-point increase (OR 0.744, 0.570–0.972, I2 = 90%). No clear benefit was observed on cancer mortality, with pooled HR of 0.935 (0.800-1.093, I2 = 0%). Significant interaction was observed for ORs according to cancer type but not between medium and high adherence for both outcomes. Our findings suggest that MD plays a protective role in cancer incidence in advanced age, but no clear effect on cancer mortality was observed.

Published: May 2024

Portions of this work were included in an oral presentation held at the Annual Meeting of the Neurological Surgeons in San Francisco, USA on October 16th, 2022.
Objective:
Spinal metastases can be associated with varying degrees of mechanical instability. The Spinal Instability Neoplastic Score (SINS) was developed to assess neoplastic-induced spinal instability. This study aimed to compare the quality of life and overall survival of patients who underwent surgical instrumentation and radiation therapy versus those who only received radiation therapy for spinal metastases. Additionally, controversy continues as to whether vertebral body replacement is mandatory.
Methods:
This study aimed to compare the quality of life and overall survival of patients who underwent surgical instrumentation or vertebral body replacement and radiation therapy compared to those who only received radiation therapy for spinal metastases. The study design was a matched-paired analysis according to the SINS score, gender, age, histology and Karnofsky Performance Index. We included all patients who received dorsal instrumentation with a carbon-PEEK system between January 2020 and December 2021. As a comparison group, we chose patients from 2018 who were treated conservatively.
Results:
42 patients were identified in each group. The median age was 67 SD +/- 14.6 and 40% were female. The most common histology was plasmacytoma observed in 31% of cases, followed by bronchial cancer in 19%. Instable and potentially unstable fractures were observed in 76% and 24% of patients, respectively. The overall survival rate was 69% and 80% in the radiation therapy and surgery / radiation therapy groups, respectively. When analyzing quality of life, we selected walking ability as the main feature. At the follow-up time point, 100% of patients in the intervention group were able to walk, noting that 12% (n=5) were in the state of incomplete paraparesis (ASIA C) at the time of surgery. In the control group, walking ability was present in 79% of cases at the follow-up time point, with an initial ASIA score distribution of 95% ASIA E and 5% ASIA D.
Conclusion:
A tailored surgical approach according to the SINS score leads to longer overall survival and higher rates of preservation of walking ability in patients with spinal metastases. There is also evidence that primary 360 degree stabilization is not necessary in the oncological setting.

Methods
A two-round online Delphi study was conducted with an inter-disciplinary panel of musculoskeletal researchers from Australia and Aotearoa New Zealand, representing various career stages and roles, including clinician researchers and consumers with lived experience of musculoskeletal conditions. Round 1 involved panellists nominating 3–10 topics about musculoskeletal trial design and conduct that they believe would be important to include in an e-learning course about musculoskeletal clinical trials. Topics were synthesised and refined. Round 2 asked panellists to rate the importance of all topics (very important, important, not important), as well as select and rank their top 10 most important topics. A rank score was calculated whereby higher scores reflect higher rankings by panellists.
Results
Round 1 was completed by 121 panellists and generated 555 individual topics describing their musculoskeletal trial learning needs. These statements were grouped into 37 unique topics for Round 2, which was completed by 104 panellists. The topics ranked as most important were: 1) defining a meaningful research question (rank score 560, 74% of panellists rated topic as very important); 2) choosing the most appropriate trial design (rank score 410, 73% rated as very important); 3) involving consumers in trial design through to dissemination (rank score 302, 62% rated as very important); 4) bias in musculoskeletal trials and how to minimise it (rank score 299, 70% rated as very important); and 5) choosing the most appropriate control/comparator group (rank score 265, 65% rated as very important).
Conclusions
This Delphi study generated a ranked list of clinical trial learning needs of musculoskeletal researchers. Findings can inform training courses and professional development to improve researcher capabilities and enhance the quality and conduct of musculoskeletal clinical trials.
Research on dual-robot cooperative path planning for multi-material additive manufacturing
Authors: Li Mingyu , Li Pengcheng , Wei Delan , Lin Jiamei , Wei Xuewen , Tian Wei , Liao Wenhe
Published: May 2024

To improve the efficiency of multi-material additive manufacturing and enhance the safety of multi-robot cooperative printing with uncertain execution delay, a dual-robot cooperative path planning method is proposed for the layer-by-layer printing mode. In the proposed algorithm, the description of the printing region is reconstructed by simply using the rectangular envelope region and two-dimensional directed line segment, and the adjacency list of the printing region is established to guide the optimization direction. Therefore, redundant information about the printing region is effectively removed, which is conducive to the optimization of the problem. A multi-round cooperation strategy with multiple synchronous starting points is proposed to accommodate uncertain execution delays by separating the space of the dual-robot printing area, so as to avoid the potential collision risk of dual-robot. To further optimize the printing efficiency, local strategies are used to reduce the makespan. Hence, a better printing order can be obtained, and states of cooperative and non-cooperative printing processes can be unified. In addition, the corresponding NC control strategy is designed for the industrial application of the cooperative strategy. The simulation result shows that this method can effectively reduce the makespan of dual-robot cooperative additive manufacturing, and accommodate the uncertain execution delay of the dual-robot.
Particle density and critical point for studying site percolation by finite size scaling
Authors: Xu Dian , Wang Shanshan , Gao Feng , Li Wei , Shen Jianmin
Published: May 2024

Machine learning has recently achieved remarkable success in studying phase transitions. It is generally believed that the latent variables of unsupervised learning can capture the information related to phase transitions, which is usually achieved through the so-called order parameter. In most models, for instance the Ising, the order parameters are simply the particle number densities. The percolation, the simplest model which can generate a phase transition, however, has a unique order parameter which is not particle number density. In this paper, we use unsupervised learning to study the relationship between particle number density, critical point, and latent variables in the site percolation model. It is found that if the input of learning is the original configuration, then the output of unsupervised learning does not convey any information related to the phase transition. Therefore, the maximum cluster is employed in order to effectively capture the critical point of the model. Unsupervised learning yields reliable results consistent with Monte Carlo simulations. We also propose a method called Fake Finite Size Scaling (FFSS) to calculate the critical value, which improves the accuracy of fitting to a great extent.
Logarithmic norm minimization of quaternion matrix decomposition for color image sparse representation
Authors: Cai Xiaomin , Ke Yi-Fen , Ma ChangFeng , Xie Yajun , Liao Ri-Wei
Published: May 2024

In this paper, incorporating the quaternion matrix framework, the logarithmic norm of quaternion matrices is employed to approximate rank. Unlike conventional sparse representation techniques for matrices, which treat RGB channels separately, quaternion-based methods maintain image structure by representing color images within a pure quaternion matrix. Leveraging the logarithmic norm, factorization and truncation techniques can be applied for proficient image recovery. Optimization of these approaches is facilitated through an alternate minimization framework, supplemented by meticulous mathematical scrutiny ensuring convergence. Finally, some numerical examples are used to demonstrate the effectiveness of the proposed algorithms.
Navigating Educational Paradigms: Examining Challenges and Perspectives of Critical Pedagogy Implementation in Ghanaian Elementary Schools
Authors: Nyamekye Ernest
Published: May 2024

Current educational reforms in Africa aim to cultivate problem-solving and critical-thinking skills among early-childhood learners through a democratic educational approach. Ghana's newly adopted standards-based curriculum prioritizes the constructivist theory of learning. However, socio-cultural norms and teachers' perceptions in Ghana may hinder this goal. This study delves into teachers' and pupils' perspectives on implementing critical pedagogy to achieve educational aims. Employing an exploratory case study design, four public elementary schools in Cape Coast were involved, engaging 12 teachers and 20 pupils. Findings indicate teachers' reluctance towards critical pedagogy, viewing it as a challenge to their authority and a potential instigator of disobedience among pupils. Conversely, pupils perceive themselves as lacking the right to critique societal norms due to established conventions. This research offers insights for policymakers to address these challenges.

Published: May 2024

It is of great significance for the engineering popularization of CO2-ECBM technology to evaluate the potential of CCUS source and sink and study the matching of pipeline network of deep unworkable seam. In this study, the deep unworkable seam was taken as the research object. Firstly, the evaluation method of CO2 storage potential in deep unworkable seam was discussed. Secondly, the CO2 storage potential was analyzed. Then, the matching research of CO2 source and sink was carried out, and the pipe network design was optimized. Finally, this study puts forward suggestions on the design of pipeline network from the perspective of time and space scales. The results show that the average annual CO2 emissions of coal-fired power plants vary greatly, and the total emissions are 58.7608 million tons. The CO2 storage potential in deep unworkable seam is huge with a total amount of 762 million tons, which can store CO2 for 12.97 years. During the 10-year period, the deep unworkable seam can store 587.6 million tons of CO2, and the cumulative length of pipeline is 251.6129 km with requiring a cumulative capital of 4.26*1010 dollars. In the process of CCUS source-sink matching, the cumulative saving mileage of carbon sink is 98.7502 km, and the cumulative saving cost is 25.669 billion dollars with accounting for 39.25% and 60.26% of the total mileage and cost, respectively. Based on the three-step approach, the whole line of CO2 source and sink in Huainan coalfield can be completed by stages and regions, and all CO2 transportation and storage can be realized. CO2 pipelines include gas collection and distribution branch lines, intra-regional trunk lines, and interregional trunk lines. Based on the reasonable layout of CO2 pipelines, a variety of CCUS applications can be simultaneously carried out, intra-regional and inter-regional CO2 transport network demonstrations can be built, and integrated business models of CO2 transport and storage can be simultaneously built on land and sea.

Objective
o investigate the impact of guideline-directed medical therapy (GDMT) during hospitalization on the prognosis of heart failure patients after acute anterior myocardial infarction.
Methods
From May 2017 to September 2022, 317 heart failure patients treated at a single center after acute anterior myocardial infarction were retrospectively investigated and analyzed based on whether GDMT during hospitalization for preventing ventricular remodeling (using at least one type of RAAS inhibitor, β receptor blocker, MRA, or SGLT2 inhibitor) was used. Patients who underwent percutaneous coronary intervention (PCI) were divided into two groups: the GDMT group (n=236) and the non-GDMT group (n=81), with a follow-up period of 12 months after PCI. The primary endpoint was the composite endpoint of all-cause death and all-cause readmission during follow-up.
Results
The incidence of primary endpoint events (10.2% vs. 19.8%, P=0.025), cardiac mortality and cardiac readmission composite events (7.2% vs. 14.8%, P=0.013), all-cause readmission events (9.3% vs. 19.8%, P=0.013), and cardiac readmission events (6.4% vs. 14.8%, P=0.019) in the GDMT group were lower than those in the non-GDMT group. Cox regression analysis revealed that the incidence of primary endpoint events, cardiac mortality and cardiac readmission composite endpoint events, all-cause readmission events, and cardiac readmission events in patients in the GDMT group were 0.397 times (HR 0.397; 95% CI0.207-0.759; P=0.005), 0.348 times (HR 0.348; 95% CI0.162-0.746; P=0.007), 0.377 times (HR 0.377; 95% CI0.195-0.730; P=0.004) and 0.320 times (HR 0.320; 95% CI0.146-0.700; P=0.004), respectively, than that in patients in the non-GDMT group. The benefits of primary endpoint events mainly come from readmission events.
Conclusion For heart failure patients who undergo PCI with acute anterior myocardial infarction, the GDMT during hospitalization reduces the incidence of readmission. And it is important to actively initiate GDMT as early as possible.
Text Comprehension Difficulties and Embodied Memory Processes

The purpose of the present study was to investigate further the semantic processing impairments of less skilled comprehenders. It tested the hypothesis that this difficulty results from an alteration in the multimodal integration mechanism involved in knowledge emergence as described within multi-trace memory models. To test this assumption, Brunel et al.’s (2010) Experiment 2 was adapted for 27 skilled comprehenders and 32 less skilled comprehenders’ adolescents from the 7th and the 8th Grades. The experiment was divided into an integration phase and an experimental phase. During the integration phase, participants had to categorise two geometric shapes, one of which was systematically presented simultaneously with a white noise. To determine whether the white noise has been integrated as a feature of the shape, the experimental phase used a priming paradigm in which the shapes categorised previously were used as primes. The targets were objects that are usually associated with a sound or not. Participants had to categorise the targets’ size. The analysis that was carried out on the correct response times revealed that only skilled comprehenders showed the priming effect observed in adults in Brunel et al.: they were faster to categorise noisy objects when preceded by sound primes than by silent primes. These results suggest that less skilled comprehenders did not integrate the sound with the shape into memory during the integration phase, resulting later in difficulties in the emergence of the trace from memory. These findings are discussed within both embodied and memory-based approaches to reading comprehension.

Spotted Hyena Optimizer (SHO) is a population-based metaheuristic algorithm inspired by the spotted hyenas’ social behavior, and it is developed for solving global optimization problems. SHO has shown superior performance over its competitive metaheuristic algorithms in solving benchmark function optimization problems and engineering design problems. However, it suffers premature convergence in local optima due to its lack of exploration while solving multi-modal optimization problems. This article proposes an improved SHO, namely quantum SHO (QSHO), inspired by quantum computing. The QSHO implements a quantum computing mechanism to promote its exploration ability. The novel method is tested on well-known IEEE CEC2013 and IEEE CEC2017 benchmark suits with 30 and 50 dimensions and four real-world engineering optimization problems. The results of QSHO are compared with that of Classical SHO, improved SHO (ISHO), Modified SHO (MSHO), Oppositional SHO with mutation operator (OBL-MO-SHO), SHO with space transformation search (STS-SHO), Quantum Salp Swarm Algorithm (QSSA), and Chimp Optimization Algorithm (ChOA). The results are analyzed using the Wilcoxon Signed Rank Test (WSRT) and Friedman Test. The empirical results show that QSHO statistically outperforms other compared algorithms for both benchmark problem suits with both 30 and 50 dimensions. In addition, we have assessed the QSHO in four real-world engineering optimization problems and the QSHO statistically outperforms the competitive algorithms.
A descriptive, prospective cohort study of the somatic and psychological health impacts of immigration detention on asylum seekers and refugees
Authors: Sherif Bafreen , Hocking Debbie , Rees Susan , Sundram Suresh
Published: May 2024

Background
It is estimated that there are over 130 million forcibly displaced people worldwide, including refugees and asylum seekers. Some countries, such as Australia, have attempted to contain unplanned humanitarian flows using immigration detention. Globally, studies have consistently demonstrated the deleterious somatic and mental health impacts of immigration detention, with high levels of distress documented among detained refugees and asylum seekers. However, the cumulative and persistent effects of indeterminate immigration detention on the prospective somatic and mental health of refugees and asylum seekers are unclear and poorly quantified.
Method
This prospective, mixed-methods cohort study will recurrently assess the somatic and mental health of adult asylum seekers and refugees (ASR) with an experience of Australian Government-sponsored immigration detention greater than 28 days. ASR ≥ 18 years old released from immigration detention will be assessed at 0, 3, 6, and 12 months and annually thereafter for up to 10 years. Five self-report scales (HSCL-25, HTQ, WHODAS 2.0, BPI-SF, and PHQ-15) and the MINI Structured psychiatric interview will measure symptoms of depression, anxiety, post-traumatic stress, pain intensity and severity, somatic symptoms, and functional impairment. This study will describe the health profiles of individuals who were subjected to an indeterminate period of immigration detention. It will also identify emergent psychological disorders associated with detention, engagement in treatment, and the functional status of this cohort. Additionally, pre-existing health records will be accessed to identify current and previous health status and assess changes in these health indices.
Discussion
This is a cohort study with no comparable population described previously in the literature. As such, the data will provide invaluable information regarding the temporal health impacts of immigration detention associated with insecure visa status. These data may be used to inform health service planning and future policy formulation in national and international contexts with the potential to improve health outcomes for asylum seekers and refugees in host countries.
