The perturbations of the ionosphere which are observed prior to significant earthquakes (EQs) have long been investigated and could be considered promising for short-term EQ prediction. One way to monitor ionospheric perturbations is by studying VLF/LF electromagnetic wave propagation through the lower ionosphere between specific transmitters and receivers. For this purpose, a network of eight ...

Macroalgae communities constitute one of the ecological quality elements for the evaluation of the ecological quality status (EQS) of coastal and transitional waters, required to implement the WFD. While these algae are natural components of estuarine systems and play important roles in several estuarine processes, macroalgal blooms are of ecological concern because they can reduce the habitat ...

In lung transplantation, cold preservation is an important process. However, the mechanical changes in the airway and tissue during cold preservation, especially before reperfusion, are unknown. To test the hypothesis that the mechanical changes in the airway and lung parenchyma start during cold preservation, we investigated the mechanical properties of the rat lung as a whole organ and in exc...

The primary objective of the paper is to quantify the mass scattering and absorption efficiencies (MSE and MAE) of different aerosol source types observed at urban (Barcelona-BCN; MAE only), regional background (Montseny-MSY), and remote background (Montsec-MSA) sites in the northwestern (NW) Mediterranean region. To accomplish this, the authors applied a multi-linear regression model (MLR; Eqs...

15 second of the hydrodynamical Eqs. 11. Clearly, this result may open new perspectives for the theoretical prediction and the experimental search for coherent behaviors of anharmonic quantum systems.

A theoretical model of adolescent behavior is examined separately for males and females (N = 722). The model hypothesizes that depression and self-derogation may lead to a lack of purpose in life, which, in turn, may lead to suicide ideation and substance use. Confirmatory factor analyses and structural equation procedures were used to examine the model, using Bentler's (1984) EQS computer prog...

TETRAD n, a fully automated successor to the TETRAD program, is intended to aid in the respecification of underspecified linear causal models, or structural equation models. The performance of TETRAD II is compared with the automatic respecification procedures in the EQS and LISREL VI programs using 360 simulated data sets from nine different linear models containing "latent" or unmeasured vari...

Predicting the susceptibility of a specific part landslide (SSPL) involves predicting likelihood that (e.g., entire landslide, source area, or scarp) will form in given area. When SSPL, samples are far less than non-landslide samples. This class imbalance makes it difficult to predict SSPL. paper proposes an advanced artificial intelligence (AI) model based on dice-cross entropy (DCE) loss func...

where N is the total number of neurons. The synapses defined by Eqs. (2) and (3) are linear: The changes M;J induced by the addition of a new pattern have a fixed magni«de, IJJJ p'Q'/N + 1/N, which is independent of previous mcHlor1cs. The statistical mechanics of Hopfield's model, Eqs. (1)-(3), has been recently studied2 in the limit of N ~ ~. Three classes of metastable states have been found...
