The utilization of solar power is one the most effective approaches to achieve goal energy conservation and emission reduction for industrial areas. However, temperature collected heat in a typical non-concentrating collector normally lower than 90 degrees Celsius, which indeed dissatisfies demand required this industry. Thus, order obtain an efficient source heat, condensed heating technology will be put into practice accordance with features low density intermittence corresponding power....

Information awareness about COVID-19 spread through multiple channels can stimulate individuals to vaccinate protect themselves and reduce the infection rate. However, may lose competency over time due decreasing quality of information fading awareness. This paper introduces programs, which not only change people from unaware aware state, but also state. Then an SEIRM/V mathematical model is derived study influence programs on individual vaccination behavior. We evaluate dynamical evolution...

The vaccines are considered to be important for the prevention and control of coronavirus disease 2019 (COVID-19). However, considering limited vaccine supply within an extended period time in many countries where COVID-19 booster shot taken new developed suppress mutation virus, designing effective vaccination strategy is extremely reduce number deaths infections. Then, simulations were implemented study relative reduction morbidity mortality allocation strategies by using proposed model...

The widespread use of effective COVID-19 vaccines could prevent substantial morbidity and mortality. Individual decision behavior about whether or not to be vaccinated plays an important role in achieving adequate vaccination coverage herd immunity.This research proposes a new susceptible-vaccinated-exposed-infected-recovered with awareness-information (SEIR/V-AI) model study the interaction between information dissemination. Information creation rate sensitivity are introduced understand...

Journal impact factor is widely used in research evaluation. By using the 2016 Citation Reports, we find that high journals publish more publications than expected and low less expected. Our findings may be useful to optimize journal based evaluation system.

Abstract In this paper, we propose a new susceptible–vaccinated–exposed–infected–recovered with unaware–aware (SEIR/V‐UA) model to study the mutual effect between epidemic spreading and information diffusion. We investigate dynamic processes of Kinetic equation derive expression for stability by eigenvalues Jacobian matrix. Then, validate Monte Carlo method numerical simulation on two‐layer scale‐free network. With outbreak COVID‐19, spread in China prompted drastic measures transmission...

We propose and demonstrate a reconfigurable logic gate based on single spin-orbit torque magnetic tunnel junction (SOT-MTJ) device operated by unipolar voltage inputs. The SOT-MTJ used in the can be switched between high low resistance state when large small amplitude pulses inject to it. Based this switching characteristic, gates of XOR, XNOR NOT are designed realized different with same sign. Compared spin logics bipolar current signals as inputs, our implementation uses much less...

China's strict "dynamic zero-COVID" policy resulted in low infection and mortality rates due to public cooperation top-down authority involvement. However, the abrupt abandonment of this on December 7, 2022, led a surge infections, strained medical resources, decreased trust authorities. This study aims investigate shift from pandemic fatigue cognitive dissonance its impact authorities post-policy change. Conducted mainland China March 8 23, 2023, used an online snowball sampling method...

In this paper, we propose a nonlinear coupled model to study the two interacting processes of awareness diffusion and epidemic spreading on same individual who is affected by different neighbor behavior status multiplex networks. We achieve topology scenario kinds factors, one perception factor that can change interplay between layers networks other neighbors’ infection rate in each layer. According microscopic Markov chain approach (MMCA), analyze dynamical evolution system derive...

The aim of this study is to describe blood lead levels (BLLs) and the prevalence elevated (EBLLs) in children aged 0-6 years old analyze BLL trend from 2009 2013 China.A total 124,376 were recruited for January 1st December 31st 2013. Their analyzed using atomic absorption spectrometry.The median was 64.3 μg/L (IQR: 49.6-81.0), range 4.3-799.0 μg/L. Blood significantly higher boys (66.0 μg/L) than girls (61.9 (P<0.001). overall BLLs≥100 10.54% Hunan Province. Between 2013, EBLLs (≥100...

Key points A more general and continuous form of ‘A short history SHELX’ phenomenon has been found. The Review Particle Physics (RPP) series, which is called the bible in particle physics field, highly cited by other research papers. RPP found different journals affected host journal's impact factor publication size. provides a big or small, but temporary, boost to its factor.

Cross-axis effect, which is inherent to anisotropic magnetoresistive sensor (referred as AMR sensor), would have an impact on accurate measurement of magnetic field. For non-orthogonal system, model and compensation algorithm cross-axis effect for three-axis were established. Taking proton precession magnetometer a standard, non-magnetic rotary table used outdoor experiments. According test data, Newton-Raphson iteration method was utilized calculate parameters. The results showed that...

In order to investigate scale-free network invulnerability, the entire by two indicators effectiveness E(G) and average path length L(G), reconnection policy of system was studied. Based on previous research that maximum nodes in are attacked neighboring disconnected, strategy with only remaining or according Euclidean distance is proposed. shortest node degree there four strategies. Firstly, BA model complex established based theory. Secondly, this basis, Random, Degree, SLP, SLP-Degree...

Power allocation is a key issue for the application of relays in communication system.With proper power strategy, performance entire system can be improved and overheads relay would reduced. However, most cases, uniform (UPA) strategy still widely utilized, which wastes limited resources thus degrades quality service (QoS). Therefore, this paper, we will compare optimal (OPA) with UPA decode-and-forward (DF) station. Moreover, direct transmit link between source destination considered. As...

Abstract The development of health literacy in China is relatively slow, and there are fewer scales, which difficult to measure. Therefore, this study aims promote the through translation application European Health Literacy Survey Questionnaire (HLS-EU-Q47). scale was translated into Chinese, back-translated, culturally adapted finally subjected psychometric evaluation. A multi-stage stratified sampling method used select 2504 residents test reliability validity a questionnaire on literacy....

In this paper, we consider frequency planning of orthogonal division multiple access (OFDMA) based cellular networks, with two-hop decode-and-forward relay stations (RSs). We develop a new framework for the mathematical modeling problem, which aims at suppressing multi-links interference and enhancing spectral efficiency. The concept incidence coloring from modern graph theory is utilized to recast original problem guide solution perspective.

Population movements had a significant impact on the spread of COVID-19, and vaccination is considered most effective means for humans to face viral infections. This study identifies optimal control strategy COVID-19 prevention control, explores short-term long-term migration proportion vaccine allocation between two regions. We proposed establish SIR (Susceptible-Infectious-Recovered) model determine stability by calculating disease free equilibrium Jacobi matrix model. then established...

Post-traumatic stress symptoms (PTSS) and post-traumatic growth (PTG) might develop after a major trauma, but their neurological bases are largely unknown. Here, we used structural magnetic resonance imaging acquired prepandemic to explore the neuroanatomical correlates in 115 college students. The PTSS PTG scores were collected during epidemic. We found that was positively associated with gray matter volume (GMV) medial prefrontal cortex, negatively correlated GMV dorsolateral cortex. Our...
