Study on Mechanism and Main Influencing Factors of Rockburst under Complex Conditions of Hard and Deep Overburden

Shock and Vibration, 2023
Xinzhuang Coal Mine is a typical kilometer-deep rockburst mine in the Ningzheng mining area of China Huaneng Group, which is still in the capital construction period.

A weak compact jet in a soft state of Cygnus X-1 [PDF]

, 2011
We present evidence for the presence of a weak compact jet during a soft X-ray state of Cygnus X-1. Very-high-resolution radio observations were taken with the VLBA, EVN and MERLIN during a hard-to-soft spectral state change, showing the hard state jet ...

Identifying the Mechanical Parameters of Hard Coating with Strain Dependent Characteristic by an Inverse Method

Shock and Vibration, 2015
The mechanical parameters of hard coating, such as storage modulus and loss factor, are affected by preparation technology significantly and have the strain dependent characteristic.

Probing three-dimensional sodiation–desodiation equilibrium in sodium-ion batteries by in situ hard X-ray nanotomography

Nature Communications, 2015
Materials degradation—the main limiting factor for widespread application of alloy anodes in battery systems—was assumed to be worse in sodium alloys than in lithium analogues due to the larger sodium-ion radius.

Evaluation of Baseflow Modeling with BlueM.Sim for Long-Term Hydrological Studies in the German Low Mountain Range of Hesse, Germany

Hydrology, 2023
So far, research with the hydrological model BlueM.Sim has been focused on reservoir management and integrated river basin modeling. BlueM.Sim is part of the official toolset for estimating immissions into rivers in Hesse (Germany) via long-term ...

Score predictor factor analysis: Reproducing observed covariances by means of factor score predictors [PDF]

Front. Psychol. 10:1895 (2019), 2019
The model implied by factor score predictors does not reproduce the non-diagonal elements of the observed covariance matrix as well as the factor loadings. It is therefore investigated whether it is possible to estimate factor loadings for which the model implied by the factor score predictors optimally reproduces the non-diagonal elements of the ...

QBiC-Pred: quantitative predictions of transcription factor binding changes due to sequence variants

Nucleic Acids Res., 2019
Non-coding genetic variants/mutations can play functional roles in the cell by disrupting regulatory interactions between transcription factors (TFs) and their genomic target sites.

Getting a head in hard soils: Convergent skull evolution and divergent allometric patterns explain shape variation in a highly diverse genus of pocket gophers (Thomomys)

BMC Evolutionary Biology, 2016
High morphological diversity can occur in closely related animals when selection favors morphologies that are subject to intrinsic biological constraints.

Hard X-Ray Variability in M82: Evidence for a Nascent Active Galactic Nucleus? [PDF]

, 1999
We report on the detection of hard (2-10 keV) X-ray variability in the starburst galaxy M82 over the course of nine ASCA observations. Long-term variability occurred on a timescale of days, with a change in flux by a factor of up to ~4, corresponding to ...

On prognostic connection between hard cosmic ray flux decrease and leaps of cardiovascular diseases in 2008–2009 in Vilnius

Acta Medica Lituanica, 2011
Data on a prognostic relationship between the hard cosmic ray flux (HCRF) and the leaps of cardiovascular diseases (CVD) in Vilnius in 2008–2009 are presented.
