Long-range correlations in rectal temperature fluctuations of healthy infants during maturation. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Control of breathing, heart rate, and body temperature are interdependent in infants, where instabilities in thermoregulation can contribute to apneas or even life-threatening events.

Biodiversity as a Dominant Force in Shaping Ethnic Music Styles 生物多样性:塑造民族音乐风格的主导力量

open access: yesIntegrative Conservation, EarlyView.
Our findings show that plant, bird, and mammal diversity considerably shape musical features such as vocal range and ornamental sounds, more so than geography or lifestyle. Our study provides the first empirical evidence linking biodiversity to ethnic music styles. Protecting biodiversity, the musical and cultural will be protected.

Developmental dynamics of symptoms of emotional problems in childhood and adolescence: A longitudinal network analysis

open access: yesJCPP Advances, EarlyView.
This study examined how emotional symptoms co‐develop from childhood to adolescence using longitudinal data from over 11,000 children and adolescents. Network analyses revealed reciprocal links between core symptoms of anxiety and depression, with no significant differences between males and females.

Transdiagnostic symptom networks in adolescent psychopathology: A longitudinal panel network analysis

open access: yesJCPP Advances, EarlyView.
Abstract Background Understanding symptom patterns of emerging psychopathology is essential for early detection and intervention. Network analysis offers a promising approach by conceptualizing emerging psychopathology as dynamic interactions between symptoms over time.

Self-Similar Models: Relationship between the Diffusion Entropy Analysis, Detrended Fluctuation Analysis and Lévy Models

open access: yesMathematics, 2020
Financial and geophysical data, like many other low and high frequency time series, are known to exhibit some memory effects. These memory effects may be long or short, permanent or temporal depending on the event that is being modeled.

Complexity signatures in the geomagnetic H component recorded by the Tromsø magnetometer (70° N, 19° E) over the last quarter of a century [PDF]

open access: yesNonlinear Processes in Geophysics, 2014
Solar disturbances, depending on the orientation of the interplanetary magnetic field, typically result in perturbations of the geomagnetic field as observed by magnetometers on the ground.

Maternal depression across childhood and offspring young adult depression and anxiety: Testing adolescent emotion dynamics as transdiagnostic mechanisms

open access: yesJCPP Advances, EarlyView.
Abstract Background Early exposure to maternal depression can increase risk for offspring mental health problems across the lifespan. Less is known about the transdiagnostic pathways through which maternal depression influences offspring mental health risk in young adulthood.

Analysis of the structural complexity of Crab Nebula observed at radio frequency using a multifractal approach

open access: yesJournal of Physics: Complexity
The Crab Nebula is an astrophysical system that exhibits complex morphological patterns at different observing frequencies. We carry out a systematic investigation of the structural complexity of the nebula using publicly available imaging data at radio ...

Degradation of Seasonally Frozen Ground in the Three–River Source Region and Its Correlation Impact Within Precipitation–Runoff Process

open access: yesInternational Journal of Climatology, EarlyView.
This study reveals how climate change alters the water cycle in the Three Rivers Source region by degrading its important ‘solid groundwater’ (seasonally frozen ground). We found that runoff response varies by watershed and the role of permafrost decreases sharply, making water supply more dependent on rainfall and becoming increasingly vulnerable ...
