Random coefficient autoregressive processes describe Brownian yet non-Gaussian diffusion in heterogeneous systems

open access: yes, 2019
Many studies on biological and soft matter systems report the joint presence of a linear mean-squared displacement and a non-Gaussian probability density exhibiting, for instance, exponential or stretched-Gaussian tails.

TGU-Net: A Temporal Generative U-Net Framework for Real-Time Traffic Anomaly Detection

open access: yesSmart Cities
Traffic anomaly detection plays a crucial role in improving road safety and enabling timely responses to abnormal events. Recent research has explored generative and predictive models to enhance detection accuracy; however, the dynamic and complex nature

Analysis of ionospheric structure influences on residual ionospheric errors in GNSS radio occultation bending angles based on ray tracing simulations [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
The Global Navigation Satellite System (GNSS) radio occultation (RO) technique is widely used to observe the atmosphere for applications such as numerical weather prediction and global climate monitoring.

Stochastic and Discrete Time Models of Long-Range Turbulent Transport in the Scrape-Off Layer

open access: yes, 2004
Two dimensional stochastic time model of scrape-off layer (SOL) turbulent transport is studied. Instability arisen in the system with respect to the stochastic perturbations of both either density or vorticity reveals itself in the strong outward bursts ...

Tilt measurements at Vulcano Island

open access: yesAnnals of Geophysics, 2007
A network of tiltmeters has been operational on Vulcano Island for numerous years. At present, the network comprises five functioning borehole stations, four of which are installed at 8-10 m and allow recording very stable, high precision signals with ...

Unique Pre-Earthquake Deformation Patterns in the Spatial Domains from GPS in Taiwan

open access: yesRemote Sensing, 2020
Most earthquakes are considered to be caused by stress accumulating in and subsequently releasing from the crust. To extract non-linear and non-stationary earthquake-induced signals associated with stress accumulation, the Hilbert−Huang transform ...

$ZZ\gamma$ and $Z\gamma\gamma$ anomalous couplings in $\gamma p$ collision at the LHC

open access: yes, 2013
We study the sensitivity of anomalous $ZZ\gamma$ and $Z\gamma\gamma$ vertex couplings $h_3^{\gamma,Z}$ and $h_4^{\gamma,Z}$, which would be powerful sign of new physics, via the subprocess $\gamma q\to Z q$ of the main reaction $pp\to p\gamma p\to Z q X$

An image segmentation based algorithm for imaging of slow slip earthquakes

open access: yesGeodesy and Geodynamics, 2018
Laboratory experiments next to a variety of observations, especially in subduction zones, have explored the existence of a premonitory stable slow slip growth phase preceding large earthquakes.

Impact of Individual Anomalous Noise Events on the Monitoring of Traffic Noise in Urban Areas

open access: yes, 2020
At least one million healthy life years are lost every year from traffic-related noise in the western part of Europe according to the World Health Organization. Other diseases have been linked with environmental noise, such as sleep disturbance, heart illnesses or tinnitus. The Environmental Noise Directive 2002/49/EC (END) and the CNOSSOS-EU framework

Experimental study of direct photon emission in K- --> pi- pi0 gamma decay using ISTRA+ detector

open access: yes, 2004
The branching ratio in the charged-pion kinetic energy region of 55 to 90 MeV for the direct photon emission in the K- --> pi- pi0 gamma decay has been measured using in-flight decays detected with the ISTRA+ setup operating in the 25 GeV/c negative ...
