Energy management system (EMS) is able to coordinate the generation and load to ensure economic and reliable operation and improve performance metrics of microgrids (MGs). However, most the previous studies have focused mainly on the optimal dispatch of the gas turbines and/or energy storage systems inside a normal MG. Very few works have been carried out to address the potential power outage in MGs. In this study, a novel optimal approach in the EMS based on online forecasts is proposed to minimise the system-wide outages of MG, specifically through pre-emptive load shedding. Online distributed generations' output forecasts are updated to predict the state of system and characterise potential upcoming outages. Proper control strategies based on receding horizon methods are introduced in this study. Outage mitigation actions using pre-emptive load shedding are then performed to avoid power outages or minimise the duration of unavoidable outages. The effectiveness of proposed approach can be demonstrated in the presence of various fluctuations, which can be easily integrated in the EMS for both islanded and grid-connected MGs.

This study was conducted in Hezhang County, Bijie City, Guizhou Province. The soil in the zinc smelting area has been contaminated with cadmium, lead, and zinc. Therefore, these elements are the focus of this research. Rice husk biochar was used as the passivation material. The Fourier infrared spectrum was utilized to study the biochar’s morphology, element content, mineral composition, structure, and surface functional groups. Moreover, the physical and chemical properties of the biochar were analyzed to explore its passivation effect. Biochar is beneficial in the cleaning of cadmium, lead, and zinc minerals and can be used for the passivation of heavy metals in contaminated soil. This study aims to understand the detailed mechanism behind this process and provide experimental data and ideas for pollution control. The results indicate that the biochar contains many functional groups, including -OH, C-H, C-O, C=O, C=C, and C-O-C. It also consists of a significant quantity of potassium salt, calcite, and quartz. Biochar has a noticeable pore structure, and as the pyrolysis temperature increases, the pore structure becomes more developed and thinner, with a smooth surface. The main minerals in the soil are quartz, mica, zeolite, illite, and chlorite. The aromatic degree of biochar increased with pyrolysis temperature. In contrast, the aromatic degree and polarity first increased and then decreased. The 0.2-0.45 mm biochar exhibited the best passivation effect on cadmium, lead, and zinc.

Interparental conflict, a stronger and cannot be hidden family risk factor, is easily perceived by LBC and further affects LBC's internalizing and externalizing problem behaviors. Moreover, in LBC's families, interparental conflict are more likely to occur due to the poor economic status and the low quality of communication and interaction between parents. However, no research has examined the relationship between perceived interparental conflict and LBC's internalizing and externalizing problem behaviors. Besides, previous research of the association between parents and children's problem behaviors have been largely restricted to the unidirectional effect of parental traits on children. This study aimed to examine the reciprocal relationships between perceived interparental conflict and LBC's internalizing and externalizing problem behaviors following a three-wave longitudinal design. A total of 660 LBC (442 boys and 218 girls) aged 8-11 years (Mage = 9.58, SDage = 0.67 at T1) in China completed a battery of questionnaires at three time points. The results indicated that perceived interparental conflicts positively predicted LBC's internalizing and externalizing problem behaviors. In turn, LBC's internalizing problem behaviors exacerbated the perception of interparental conflicts. Furthermore, perceived interparental conflict mediated the longitudinal relation between LBC's internalizing problem behaviors and externalizing problem behaviors. The findings provide evidence for the accumulating disadvantage for LBC that results from the mutual reinforcement of perceived interparental conflict and problem behaviors over time.

In LBC's families, a large proportion of fathers migrated to other cities for work. Migrated fathers' involvement also has crucial impacts on children's development, but previous studies focused less on it. Thus, using the longitudinal data of two waves, current study examined the relationship between fathers' involvement and the LBC's mental health from the perspective of the Dual-Factor Model of Mental Health and its underlying mechanism. A total of 613 LBC at primary schools in China completed questionnaires twice about fathers' involvement, paternal and maternal attachment, life satisfaction, prosocial behavior, internalizing problems, and externalizing problems. The results showed that the total effects of fathers' involvement on LBC's life satisfaction and prosocial behavior were significant, while those on problem behaviors were insignificant. Also, father-child attachment played a mediating role in the association between fathers' involvement and the positive indicators of LBC's mental health. Meanwhile, mother-child attachment mediated the relationships between fathers' involvement and LBC's problem behaviors. The study not only highlights the positive influence of fathers' involvement on LBC as well as the relations among different subsystems in the family but also implies the different effects of paternal and maternal attachment on LBC's mental health, which brings inspiration for improving the mental health of LBC in China.

This study used the Actor-Partner Interdependence Model to examine how parents' adult attachment influences their their own and the partners' co-parenting and parent-child relationships. Participants were from a cross-sectional sample of 1313 Chinese heterosexual married couples (fathers' Mage = 39.74, SD = 5.61; mothers' Mage = 37.55, SD = 5.04) whose biological children were pupils (Mage = 10.25, SD = 2.35). Results revealed that: (a) Couple members' actor effects from adult attachment avoidance to positive and negative co-parenting and parent-child closeness and conflict were found both significant; (b) The actor effects from adult attachment anxiety to negative co-parenting and parent-child conflict were found significant, whereas only partner effect from attachment avoidance to positive co-parenting and from attachment anxiety to parent-child conflict were significant. The results highlight the negative effects of parents' attachment avoidance and anxiety on their partners' parenting function. [ABSTRACT FROM AUTHOR]

The market demand for optoelectronic devices is increasing, leading to a need for low‐cost, high‐performance image sensors that can operate effectively in challenging environments such as darkness and fog. The emerging 2D transition metal dichalcogenides (TMDs) have garnered significant interest due to their exceptional optoelectronic properties and compatibility with silicon (Si) complementary metal oxide semiconductor (CMOS) technology. However, the large‐scale synthesis of TMD films and uniform preparation of photodiode arrays remain challenging. This paper reports a synthesis method for heteroepitaxial growth of 2H‐ molybdeum diyelluride (MoTe2) semiconducting films on 3D wafer‐level Si substrates. Using this method, arrays of 2H‐MoTe2/Si heterojunction photodiodes are prepared that demonstrate excellent uniformity and 100% device yield. The photodiodes exhibit satisfactory optoelectronic properties, including a small dark current maintained within a range of 1–3 nA and a maximum responsivity of 521.1 mAW−1 under near‐infrared light at 800 nm, with rise and fall times of less than 4 ms. To demonstrate the image‐sensing capabilities of the photodiode array under visible and near‐infrared (NIR) light illumination, a complete imaging system is designed.The MoTe2/Si photodiode arrays examined in this study offer a practical solution for integrating Si‐based readout circuits and photodetector arrays on a single chip.

Objective To establish a simple model for arteriosclerosis (AS) screening to provide a viable tool for the timely identification of AS risk among residents aged 40-65 years. Methods Data were obtained from the Sleep and Chronic Diseases Program in Fuquan City. The original dataset was divided into a training subset and a validation subset (80%: 20%). LASSO and logistic regression models were used to screen variables, perform multivariate regression analyses. Internal validation was performed using the Bootstrap method. Nomogram Plot was constructed, and risk score thresholds were determined based on ROC curves to classify high-risk populations. Results RS Model was established to include age, gender, napping, sleep efficiency, sleep disorders, hypertension and diabetes, with AUC = 74.80% and a model risk score threshold = 84.20. PHC Model was established to include age, gender, napping, sleep efficiency, systolic blood pressure, fasting blood glucose, and pulse variables, with AUC = 82.80% and a risk score threshold of 78.00. Decision curves showed that both models performed well in terms of calibration and actual benefits for health management. Conclusion The two AS screening models exhibit acceptable accuracy and differentiation. Therefore, it can be applied in residents' self-health management and in primary care organizations' screening work in a large scale. [ABSTRACT FROM AUTHOR]

2D semiconductors have emerged as candidates for next‐generation electronics. However, previously reported 2D transistors which typically employ the gate‐first process to fabricate a back‐gate (BG) configuration while neglecting the thorough impact on the dielectric capping layer, are severely constrained in large‐scale manufacturing and compatibility with complementary metal–oxide–semiconductor (CMOS) technology. In this study, dual‐gate (DG) field‐effect transistors have been realized based on wafer‐scale monolayer MoS2 and the gate‐last processing, which avoids the transfer process and utilizes an optimized top‐gate (TG) dielectric stack, rendering it highly compatible with CMOS technology. Subsequently, the physical mechanism of TG dielectric deposition and the corresponding controllable threshold voltage (VTH) shift is investigated. Then the fabricated TG‐devices with a large on/off ratio up to 1.7 × 109, negligible hysteresis (≈14 mV), and favorable stability. Additionally, encapsulated TG structured photodetectors have been demonstrated which exhibit photo responsivity (R) up to 9.39 × 103 A W−1 and detectivity (D*) ≈2.13 × 1013 Jones. The result paves the way for future CMOS‐compatible integration of 2D semiconductors for complex multifunctional IC applications. [ABSTRACT FROM AUTHOR]
