Housing markets play a crucial role in economies and the collapse of real-estate bubble usually destabilizes financial system causes economic recessions. We investigate systemic risk spatiotemporal dynamics US housing market (1975–2011) at state level based on Random Matrix Theory (RMT). identify richer information largest eigenvalues deviating from RMT predictions for than stock find that component signs eigenvectors contain either geographical or extent differences house price growth rates...

Volatile organic chemicals (VOCs), a common environment pollutant, have been associated with some autoimmune diseases, but it has not clarified if VOC exposure affects sleep, and so, which VOCs affect sleep. Our study aimed to evaluate the relationship of individual sleep disorders duration. primary analytical techniques were logistic regression models multinomial models. After rigorous verification, specific N-acetyl-S-(2-carboxyethyl)-L-cysteine (CEMA), mandelic acid (MA), phenylglyoxylic...

Understanding the statistical properties of recurrence intervals (also termed return in econophysics literature) extreme events is crucial to risk assessment and management complex systems. The probability distributions correlations for many systems have been extensively investigated. However, impacts microscopic rules a system on macroscopic its are less studied. In this letter, we adopt an order-driven stock model address issue returns. We find that scaled simulated returns power-law...

We present the symmetric thermal optimal path (TOPS) method to determine time-dependent lead-lag relationship between two stochastic time series. This novel version of previously introduced TOP alleviates some inconsistencies by imposing that should be invariant with respect a reversal series after change sign. means that, if `$X$ comes before $Y$', this transforms into `$Y$ $X$' under reversal. show proposed bootstrap test lacks power and leads too often lack rejection null there is no...

The latest global financial tsunami and its follow-up economic recession has uncovered the crucial impact of housing markets on systems. Chinese stock market experienced a markedly fall during China's economy also slowed down by about 2\%-3\% when measured in GDP. Nevertheless, diverse cities seemed to continue almost nonstop mania for more than ten years. However, structure dynamics are less studied. Here we perform an extensive study analyzing representative key based both linear nonlinear...

Urban land intensive use is an important part of regional planning and plays role in the sustainable development cities. However, research on how to measure urban intensity still controversial. This paper gives a perspective multi-objective decision explore criterion process urbanization. The theory factor substitution was applied analyze mechanism different urbanization stage. Additionally, matching degree model (MDM), curve estimation model, programming were employed case study Wuhan...

We present the symmetric thermal optimal path (TOPS) method to determine time-dependent lead-lag relationship between two stochastic time series. This novel version of previously introduced TOP alleviates some inconsistencies by imposing that should be invariant with respect a reversal series after change sign. means that, if ‘X comes before Y’, this transforms into ‘Y X’ under reversal. show proposed bootstrap test lacks power and leads too often lack rejection null there is no correlation...

Understanding how industrial land is spatially allocated across regions crucial for formulating more optimised policies and regional development strategies, especially in industrialising countries. By exploiting a unique county-level cadastral dataset covering the whole China from 2009 to 2018, this paper analyzes spatiotemporal allocation of potential spatial mismatch China. We find that constituted largest single type urban use (27%) its absolute area allocative share expanded during...

The rational matching of urban land and population has become an important prerequisite for sustainable development. In this paper, the traditional scale elasticity model was improved, combined with gravity model, spatial interaction between expansion change in 618 cities China during period 2006–2021 investigated. geographical detector method used to reveal what drives them. main results were as follows: (1) China’s rate 1.83 times faster than growth 2006–2021. After implementation New-type...

Anti-Müller hormone (AMH) plays an important role in reproductive development and has a wide potential clinical application value. Phthalates have been widely found human living environment negative effects on reproduction. This study aimed to explore the relationship between urinary phthalate metabolites serum AMH level general male population. Cross-sectional analyses were performed with population of 489 men aged more than 12 years who participated National Health Nutrition Examination...

Using methods of system analysis and patent analysis, some gratifying progress about the industrial chain, scale, R&D ability, low cost had been made in solar energy industry China. But there are questions such as internal external challenges, enterprise innovation ability needing to be improved further, output quality not being high, emerging domestic market yet developed etc. Therefore, effective countermeasures just like strengthening multilateral communication, building independent...
