A scalable electrothermal model using a three‐dimensional thermal analysis model for GaN‐on‐diamond high‐electron‐mobility transistors

A scalable eletrothermal model is necessary for a high‐power amplifier design for accurate accounting of thermal effects. Toward this end, this study presents a scalable large‐signal model of gallium‐nitride (GaN) high‐electron‐mobility transistors (HEMTs) on diamond substrates. First, a three‐dimensional (3D) thermal analysis model was established. Then, a modified eletrothemal expression was proposed to predict thermal effects including scalability. For validation, the proposed model was implemented into quasi‐physics zone division (QPZD) large‐signal model. Results show that the proposed model accurately predicts the I–V curves of devices with different gate widths, gate fingers, and ambient temperatures. Moreover, the results of the model are consistent with on‐wafer measurements of 2 × 125, 4 × 125, and 10 × 50 μm of GaN‐on‐diamond HEMTs, indicating that the proposed model accurately predicts the DC–IV curves, scattering parameters, and large‐signal performance. The findings of this study can be useful for designing microwave diamond–GaN HEMT circuits.

Modular Cross-Linked Chitosan Beads with Calcium Doping for Enhanced Adsorptive Uptake of Organophosphate Anions

Chitosan beads were cross-linked at variable composition with glutaraldehyde (GA) and epichlorohydrin (EP), respectively. The beads were post-treated by impregnation with CaCl2 solution and characterized to evaluate the structure and physicochemical effect of Ca-doping. The bead adsorption properties were studied at pH 8.5 with p-nitrophenyl phosphate (PNPP), where beads cross-linked with GA showed higher uptake relative to beads cross-linked with EP. Ca-doping of GA beads showed a four-fold greater uptake (0.97 mmol. g-1) over non cross-linked (NCL) beads (0.23 mmol. g-1). By comparison, EP-based beads with Ca-doping showed a two-fold enhancement for uptake of PNPP uptake (0.90 mmol. g-1) over NCL beads. This work illustrates the utility of cross-linking and Ca-doping as modular strategies for tuning the adsorption behaviour of chitosan-based beads. The GA5-CA cross-linked beads showed favorable adsorption–desorption properties where the uptake capacity of PNPP remained relatively constant (19.6-17.5 %) .
Estimation of Aircraft-Dependent Bumpiness Severity in Turbulent Flight

Atmospheric turbulence threatens flight safety of civil aviation aircraft by inducing aircraft bumpiness. A severity estimation method of aircraft bumpiness in turbulent flight is explored according to in-situ Eddy Dissipation Rate (EDR) indicator. With the turbulence intensity derived from EDR value, a time series of longitudinal and vertical turbulence was generated according to von Karman turbulence model. In order to obtain the vertical acceleration response of aircraft, the continuous change of aerodynamic force on the assembly of wing and horizontal tail was computed by Unsteady Vortex Lattice Method (UVLM). The computing accuracy was improved by using semi-circle division and assigning the vortex rings on the mean camber surface. Furthermore, the adverse effects of control surface deflections on bumpiness severity estimation can be effectively removed by separating turbulence-induced and aircraft maneuvers-induced aerodynamic force change. After that, the variance of vertical acceleration, as the severity indicator of aircraft bumpiness, was obtained by Welch spectrum estimation. With the refined grid level, the pitching moment change due to control surface deflections can be solved accurately by UVLM. The instantaneous acceleration change obtained by UVLM approximates recorded acceleration data with better accuracy than linear transfer function model. A further test with a set of flight data on the same airway shows that compared with in-situ EDR indicator, the proposed method gives an aircraft-dependent estimation of bumpiness severity, which can not only be used to estimate in-situ bumpiness but also be applied to forecast the bumpiness severity of other different aircrafts.
Feeling Guilty and Flattering God: The Mediating Role of Prayer

Ingratiation refers to acts of flattery, typically given by a low-power person to a high-power one, performed to gain acceptance and approval. This study investigates ingratiation in the religious setting, asking whether people feeling high levels of guilt or shame tend to manifest such ingratiating behavior toward God. The study aimed to examine the mediating role of prayer in the relationship between guilt and shame and ingratiation toward God. A total of 148 respondents (80 women and 68 men) participated in the study. The Religious Ingratiation Scale, the Content of Prayer Scale, and the Guilt and Shame Proneness Scale were applied to the research. The results showed that feeling guilty increased the tendency to ingratiation toward God. Prayer was the significant mediator in this relationship. People high in guilt tend to flatter God by offering more adoration and fewer repine prayers.
Factors predicting six-month exclusive breastfeeding among mothers in Ho Chi Minh City, Vietnam

Exclusive breastfeeding (EBF) rates continue to be low in Vietnam. This study aimed to determine the factors predicting 6-month EBF among mothers in Ho Chi Minh City, Vietnam. ,A cross-sectional study was conducted with 259 mothers of infants aged between six to nine months at well-baby clinics in Ho Chi Minh City. The questionnaires used for data collection included personal background questionnaire, perceived benefits of breastfeeding scale, breastfeeding self-efficacy scale-short form, perceived barriers to breastfeeding scale and the family support of breastfeeding scale. Descriptive statistics, bivariate and multiple logistic regression were used for data analysis. ,About 32% of the Vietnamese mothers practiced 6-month EBF. By increasing one unit of perceived benefits of breastfeeding, perceived self-efficacy in breastfeeding and family support, the mothers' likelihood to give 6-month EBF would increase 19% (AOR = 1.19, 95% CI = 1.08, 1.31), 12% (AOR = 1.12, 95% CI = 1.04, 1.19) and 10% (AOR = 1.10, 95% CI = 1.04, 1.16), while previous breastfeeding experience, maternal age and maternal education could not significantly contribute to the 6-month EBF. ,This is the first study in Vietnam using a nursing model, the health promotion model, as a framework to identify factors predicting 6-month EBF. An effective program for promoting EBF could be developed by manipulating and tailoring the predicting factors to fit the Vietnamese mothers' needs through a mother class, lactation clinic or individual approach.
Comparative Study the Impact of Single and Double Vacancy Defects in BC3 Nanosheet on the Acetaminophen Detection

Density functional theory (DFT) calculations was used to investigate the interaction between the prefect and defected boron carbide (BC3) monolayer nanosheet and conventional acetaminophen (AP) drug. The obtained findings indicate no considerable interaction between BC3 nanosheet and AP drug. Thus, perfect BC3 is not highly sensitive against AP presence regarding weak interactions. We explored if introducing single vacancy (SV) and double vacancy (DV) defect in prefect BC3 nanosheet can enhance the interaction with AP drug. The adsorption energy of AP drug on the DV-BC3 and SV- BC3 surface were calculated about -15.32 and -23.78 kcal/mol, respectively. After AP adsorption, a considerable change of bang gap and work function of DV-BC3 and SV-BC3 was observed while only the electrical bang gap of perfect BC3 was changed after AP adsorption and the work function change was negligible. It can be concluded that both defected BC3 sheets can act as both electrical and work function sensor types while the perfect BC3 can only act as an electrical sensor. The adsorption energy is remarkably changed in media with higher dielectric constant. Additionally, AP adsorption dramatically changes the magnetic properties of DV-BC3.
Determinants of Psychology Students’ Study Satisfaction

Understanding characteristics that contribute to psychology students’ academic success is important to better support them during their studies. Referring to person–environment fit theory, we examined effects of study-relevant characteristics (self-efficacy beliefs, self-assessed level of information about the study program) on subjective criteria of success (persistence with the choice of study subject, later study satisfaction) and controlled for effects of grade point average (GPA) and mathematical skills. We present a longitudinal survey study including five cohorts of first-year students (total N = 854). Mediation models (N = 254) revealed that self-efficacy and level of information at study entry predicted students’ persistence at the end of the first semester, which predicted satisfaction at the end of the second semester. In the presumed overall model we found total effects of self-efficacy and level of information, with direct and indirect effects (via persistence) on satisfaction, and no total or direct effects of GPA and mathematical skills, but an indirect effect of GPA on satisfaction. Thus, psychology students’ satisfaction substantially depends on study-relevant characteristics and less on skills. An enhancement of students’ self-efficacy beliefs and comprehensive information for those who are interested in the subject might help to increase satisfaction and thus success.
Tussocks Enduring or Shrubs Greening: Alternate Responses to Changing Fire Regimes in the Noatak River Valley, Alaska

As the Arctic warms, tundra wildfires are expected to become more frequent and severe. Assessing how the most flammable regions of the tundra respond to burning can inform us about how the rest of the Arctic may be affected by climate change. Here we describe ecosystem responses to tundra fires in the Noatak River watershed of northwestern Alaska using shrub dendrochronology, active‐layer depth monitoring, and remotely sensed vegetation productivity. Results show that relatively productive tundra is more likely to experience fires and to burn more severely, suggesting that fuel loads currently limit tundra fire distribution in the Noatak Valley. Within three years of burning, most alder shrubs sampled had either germinated or resprouted, and vegetation productivity inside 60 burn perimeters had recovered to prefire values. Tundra fires resulted in two phases of increased primary productivity as manifested by increased landscape greening. Phase one occurred in most burned areas 3–10 years after fires, and phase two occurred 16–44 years after fire at sites where tundra fires triggered near‐surface permafrost thaw resulting in shrub proliferation. A fire‐shrub‐greening positive feedback is currently operating in the Noatak Valley and this feedback could expand northward as air temperatures, fire frequencies, and permafrost degradation increase. This feedback will not occur at all locations. In the Noatak Valley, the fire‐shrub‐greening process is relatively limited in tussock tundra communities, where low‐severity fires and shallow active layers exclude shrub proliferation. Climate warming and enhanced fire occurrence will likely shift fire‐poor landscapes into either the tussock tundra or erect‐shrub‐tundra ecological attractor states that now dominate the fire‐rich Noatak Valley.
Improved Simulations of Global Black Carbon Distributions by Modifying Wet Scavenging Processes in Convective and Mixed‐Phase Clouds

In‐cloud wet scavenging dominates the wet removal of aerosols in the atmosphere, but is not well represented in climate models. Aircraft measurements of black carbon (BC) concentrations suggest that models commonly overestimate BC concentrations in the upper troposphere of the tropics by more than one order of magnitude but underestimate BC burdens in polar latitudes. In this study, we improved the in‐cloud wet scavenging parameterizations for convective clouds and mixed‐phase clouds to better characterize BC abundances in the remote atmosphere (remote oceans and polar regions) with a global model, CAM5‐ATRAS2. The modified wet scavenging processes in the model achieved a more realistic simulation of BC concentrations over both the tropics and the Arctic. The new, unified scheme for vertical transport and wet removal during deep convection generally reproduced the observed low mixing ratios (about 0.1 ng kg−1) of BC in the middle and upper troposphere over the tropics, and the Wegener–Bergeron–Findeisen process (WBF) lowered the wet removal efficiency of BC from mixed‐phase clouds and consequently increased BC burdens in the Arctic by about a factor of 2. The BC direct radiative forcings increased by 20% globally (from 0.26 to 0.31 W m−2), and more importantly by a factor of 2 in the Arctic (from 0.09 to 0.18 W m−2). Our results indicated that good agreement between modeled and observed BC concentrations could be obtained in the remote atmosphere without requiring the relatively short global BC lifetime (∼4 days) suggested by previous studies.
Study on the Influence of Cultural Contact and Tourism Memory on the Intention to Revisit: A Case Study of Cultural and Creative Districts

Cultural and creative tourism is emerging in tourism industry with the potential to be sustainable as an important carrier of traditional culture. This study adopts stimulus–response theory in a cultural integration perspective to investigate how tourists’ cultural memories, cultural contact, and attitude to culture affect their revisit intention. With the questionnaire survey responses from 651 tourists and structural equation modeling method, it was found that tourists’ cultural contact affected their revisit intentions directly and indirectly through cultural memory. Attitude to culture played critical moderating roles in the effects of tourists’ cultural contact on their cultural memory and revisit intention, but it had no significant impact on the relationship between tourists’ cultural memory and their revisit intention. This study indicates that cultural memory dominates tourists’ behavioral decisions, while attitude to culture highlights different effects at different influence paths. The findings provide marketers and managers with strategies for the sustainable development of cultural and creative districts.
Rapid Determination of Anthracene and Benzo(a)pyrene by High-Performance Liquid Chromatography with Fluorescence Detection

ABSTRACT A rapid and simple method was optimized and validated for the separation and quantification of anthracene and benzo(a)pyrene, two of the most toxic polycyclic aromatic hydrocarbons, at ultratrace levels in aqueous samples by direct injection. The determination of anthracene and benzo(a)pyrene was performed by reverse-phase high-performance liquid chromatography (HPLC) with fluorescence detection. A fractional factorial matrix and a Box–Behnken design were chosen for screening and optimization purposes, respectively. The optimized parameters that significantly influenced the system were the flow rate (1 mL min−1), mobile-phase strength (90% acetonitrile:10% deionized water), column temperature (35°C), and excitation wavelength (254 and 267 nm for anthracene and benzo(a)pyrene, respectively). The injection volume and emission wavelength were fixed at 100 µL and 416 nm, respectively. The quantification limits were 75 ng L−1 for anthracene and 30 ng L−1 for benzo(a)pyrene. The relative standard deviations for the recovery and intra and interday precision values were lower than 20%. The method allows the analysis of aqueous samples with a good resolution for anthracene and benzo(a)pyrene below values permitted by the recently developed European Directive 2013/39/EU for inland surface waters. In addition, this work provides guidelines for the simultaneous optimization of several parameters by experimental design.
Planar dynamic modelling of round link chain drives considering the irregular polygonal action and guide rail

Round link chain drives can be sorted into the transmission, parallel conveyor and non-parallel conveyor systems according to their applications and guide rail’s layouts. The polygonal action in these systems is irregular. Compared with the literature, this paper proposes a more accurate modelling approach to capture the dynamic behaviour of round link chain drives, which can consider both the irregular polygonal action and non-parallel guide rail’s layout. The dynamic models of the three types of round link chain drives are developed based on the finite segment method. The chain is divided into multiple discrete segments that are connected by Kelvin models. To account for the irregular polygonal action, the sprocket is equivalent to an irregular polygon. To consider the non-parallel guide rail’s layout in the conveyor system, the chain segment out of the guide rail and the corresponding sprocket are treated as a swinging-block mechanism. The proposed approach is applied to model a scraper conveyor. Simulation results show that the irregular polygonal action and non-parallel guide rail’s layout greatly increase the fluctuation of the chain tension force.
Activation of glucocorticoid receptors is associated with the suppression of antioxidant responses in the liver of goats fed a high-concentrate diet

Abstract This study investigated changes in oxidative stress and the relevant mechanisms in the liver of goats fed a high-concentrate (HC) diet for 5 weeks. Twelve goats were randomly assigned to a low-concentrate (concentrate-to-forage = 55:45, LC, n = 6) or HC diet (concentrate-to-forage = 90:10, n = 6), with dry matter as the base. Enzyme activity assays, real-time polymerase chain reaction and western blotting were used to evaluate antioxidant parameters and gene expression in the liver. Superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), total nitric oxide synthase activity and total antioxidant capacity (T-AOC) in the liver declined (p < .01) in HC-fed goats compared to those in LC-fed goats. The mRNA levels of GPX1, CAT and SOD1 were down-regulated (3.69, 47.37 and 27.61%, respectively) in HC-fed goats compared to those in LC-fed goats. Furthermore, glutathione S-transferase M1 (GSTM1) was upregulated (466.35%, p < .01) in the liver of HC-fed goats. The mRNA and protein levels of the nuclear factor E2-related factor 2 (NRF2) and total glucocorticoid receptor (GR) declined (p < .05) in HC-fed goats (by 28.57, 33.1, 30.85 and 34%, respectively). However, the nuclear translocation of GR increased (p < .05; by 44.75%) in HC-fed goats. Negative correlations were detected for hepatic nuclear GR protein expression with hepatic CAT activity and GPx activity. In conclusion, feeding an HC diet to goats for 5 weeks suppressed NRF2-dependent antioxidant responses and enhanced GR nuclear translocation in the liver. Highlights Feeding goats high-concentrate diets suppresses NRF2-dependent antioxidant responses in liver, downregulating NRF2 and altering SOD1, GPx and CAT activity. This suppression of NRF2-dependent antioxidant responses is associated with GR activation in the liver of goats.
Interpersonal Violence and Mental Health Outcomes: Mediation by Self-efficacy and Coping

ABSTRACT There is a compelling need to explore the mechanisms linking violence to mental health. This study tested the mediating role of self-efficacy and coping in the association between victimization and mental health. Data were obtained from 422 adults (aged 18-77; M = 30.05; SD = 10.93). Self-efficacy and maladaptive coping strategies mediated the association between physical victimization and anxiety, and the association between psychological victimization and satisfaction with life anxiety and depression. Self-efficacy and adaptive coping also mediated the association between psychological victimization and satisfaction with life. This study provides important implications for research and practice.
Income smoothing and firm value in a regulated market: the moderating effect of market risk

This study aims to examine the impact of income smoothing on the value of firms in a regulated security market, moderated by market risk. This is based on the prevalence of accounting scandals resulting in the collapse of firms which has been attributed to the opportunistic behaviors of managers. ,The ex post facto research design was employed, and as such, data were gathered from secondary sources. The quantitative approach was also used in the study. Furthermore, the system generalized method of moments (Blundell–Bond) panel estimation technique was used for analyzing the data. Income smoothing was measured using the accrual based methods, while firm value was measured using share price. ,The study found that income smoothing has a negative significant impact on firm value. The study also revealed that market risk is a significant variable that defines the relationship between income smoothing and firm value. ,Testing the moderating effect of market risk on the relationship between income smoothing and firm value is unique to this study, particularly from a regulated security market and emerging economy.
Nutritional, antioxidant, and quality characteristics of novel cookies enriched with mushroom (Cordyceps militaris) flour

ABSTRACT This study was conducted to investigate the effects of incorporating varying proportions of nutraceutical-rich mushroom (Cordycepes militaris) flour (1%, 3% and 5%) on the physicochemical, antioxidant and sensory properties of cookies. Results showed that the contents of crude protein, ash and fiber of supplemented coo kies were higher than that of control cookies. Spread ratio and hardness decreased as the C.militaris flour incorporation level increased. The color values of cookies also varied with the increasing levels of C. militaris flour. Furthermore, fortification of C. militaris flour improved the functional quality of cookies by significantly enhancing the phenolic contents and antioxidant activities (P < 0.05). Sensory evaluation of cookies indicated that the addition of 3% C. militaris flour was more acceptable. Overall, enriched cookies have more functional components and effective antioxidant capacity than plain wheat cookies. Their supplementation could provide the consumers a novel cereal-based product with health-promoting benefits.
