On the existence of earthquake precursors

open access: yesAnnals of Geophysics, 1999
Earthquake prediction based on precursors can aim to provide fully quantified, time-varying, synoptic forecasts, which do not depart from physical and geological principles, and are amenable to formal testing.

EZH2 identifies the precursors of human natural killer cells with trained immunity

open access: yesCancer Biology & Medicine, 2021
Objective: Trained immunity of natural killer (NK) cells has shown great potential in the treatment of cancers by eliciting enhanced effector responses to restimulation by cytokines or cancer cells for long time periods after preactivation.

A Precursor of Market Crashes [PDF]

open access: yes, 2005
In this paper, we quantitatively investigate the properties of a statistical ensemble of stock prices. We focus attention on the relative price defined as $ X(t) = S(t)/S(0) $, where $ S(0) $ is the initial price.

Ionospheric VTEC anomalies before Ms7.1 Yushu earthquake

open access: yesGeodesy and Geodynamics, 2011
Vertical total electron content is examined to check whether the Ms7.1 Yushu earthquake on April 14, 2010, may have caused any anomalous ionospheric changes. The result shows two TEC increases over the epicenter vicinity on April 1 and 5; these anomalies

Precursor of Inflation

open access: yes, 2013
We investigate a nonsingular initial state of the Universe which leads to inflation naturally. The model is described by a scalar field with a quadratic potential in Eddington-inspired Born-Infeld gravity.

GRB Precursors in the Fallback Collapsar Scenario [PDF]

open access: yes, 2007
Precursor emission has been observed in a non-negligible fraction of gamma-ray bursts.The time gap between the precursor and the main burst extends in some case up to hundreds of seconds, such as in GRB041219A, GRB050820A and GRB060124.

Precursor flares in OJ 287

open access: yes, 2012
We have studied three most recent precursor flares in the light curve of the blazar OJ 287 while invoking the presence of a precessing binary black hole in the system to explain the nature of these flares.

Influence of calcination conditions on structural and solid‐state kinetic properties of iron oxidic species supported on SBA‐15 [PDF]

open access: yes, 2019
Iron oxidic species supported on silica SBA-15 were synthesized with various iron loadings using two different FeIII precursors. The effect of varying powder layer thickness during calcination on structural and solid-state kinetic properties of FexOy/SBA-
