Hydrological Processes, Volume 40, Issue 4, April 2026.Warm ENSO phase events weaken Asian monsoons, reducing precipitation and TWS in northern and southern ICP, while central ICP's bowl‐shaped topography increases TWS. Seasonally, the Indian Monsoon brings abundant rainfall during May–September, which lags into TWS by 2 months.

Humidity's influence on visible region refractive index structure parameter $C_n^2$ [PDF]
, 2006 In the infrared and visible bandpass, optical propagation theory conventionally assumes that humidity does not contribute to the effects of atmospheric turbulence on optical beams. While this assumption may be reasonable for dry locations, we demonstrate

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Comparison of methods for the identification of mesoscale wind speed fluctuations
Meteorologische Zeitschrift, 2017 Mesoscale wind speed fluctuations influence the characteristics of offshore wind energy. These recurring wind speed changes on time scales between tens of minutes and six hours lead to power output fluctuations. In order to investigate the meteorological

Recognizing Parkinson’s disease gait patterns by vibes algorithm and Hilbert-Huang transform
, 2021 Parkinson’s disease (PD) is the second most common neurodegenerative disorder all over the world. There are resting tremor, bradykinesia, and rarely dystonia, all of which are motor symptoms, among the manifestations of PD.

IRIS RECOGNITION BASED ON HILBERT–HUANG TRANSFORM
Advances in Adaptive Data Analysis, 2009 As a reliable approach for human identification, iris recognition has received increasing attention in recent years. This paper proposes a new analysis method for iris recognition based on Hilbert–Huang transform (HHT). We first divide a normalized iris image into several subregions.

Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract Obtaining broadband ground motion simulations consistent with observed records is essential for seismic modeling, and the key to achieving this lies in a physically reasonable source representation. Only a scientifically constrained broadband source can effectively generate broadband ground motions.

Extreme-Point Symmetric Mode Decomposition Method for Data Analysis
, 2013 An extreme-point symmetric mode decomposition (ESMD) method is proposed to improve the Hilbert-Huang Transform (HHT) through the following prospects: (1) The sifting process is implemented by the aid of 1, 2, 3 or more inner interpolating curves, which ...

Cognitive Radio Sensing Using Hilbert Huang Transform
Wireless Engineering and Technology, 2010 Vast segments of the frequency spectrum are reserved for primary (licensed) users. These legacy users often un-der-utilize their reserved spectrum thus causing bandwidth waste. The unlicensed (secondary) users can take advantage of this fact and exploit the spectral holes (vacant spectrum segments). Since spectrum occupancy is transient in nature it is
