Identification of the Noise Model in the Time Series of GNSS Stations Coordinates Using Wavelet Analysis

Remote Sensing, 2018
Analysis of the time series of coordinates is extremely important in geodynamic research. Indeed, the correct interpretation of coordinate changes may facilitate an understanding of the diverse geophysical processes taking place in the earth’s ...

Mapping Opencast Iron Mine and Mine Solid Waste Based on a New Spectral Index From Medium Spatial Resolution Satellite Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Opencast iron mine and mine solid waste (OIM-MSW) are closely associated with a wide range of environmental issues, such as destroying soil structure, affecting air quality, and damaging biodiversity.

Measuring the spectral running from cosmic microwave background and primordial black holes

, 2018
We constrain the spectral running by combining cosmic microwave background (CMB) data, baryon acoustic oscillation (BAO) data and the constraint from primordial black holes (PBHs).

Small field inflation and the spectral index

Journal of Cosmology and Astroparticle Physics, 2014
It is sometimes stated that $n_s = 0.98$ in hybrid inflation; sometimes that it predicts $n_s >1$. A number of authors have consider aspects of Planck scale corrections and argued that they affect these predictions. Here we consider these systematically, describing the situations which can yield $n_s =0.96$, and the extent to which this result ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Regularized energy-dependent solar flare hard x-ray spectral index

, 2005
The deduction from solar flare X-ray photon spectroscopic data of the energy dependent model-independent spectral index is considered as an inverse problem.

The Spectral Index Distribution of EGRET Blazars: Prospects for GLAST [PDF]

, 2007
The intrinsic distribution of spectral indices in GeV energies of gamma-ray--loud blazars is a critical input in determining the spectral shape of the unresolved blazar contribution to the diffuse extragalactic gamma-ray background, as well as an ...

RUNNING OF THE SPECTRAL INDEX IN NONCOMMUTATIVE INFLATION

International Journal of Modern Physics A, 2005
We study the cosmological implications of the space–space noncommutative inflation and present formulae for the spectral index and its running. Our results show that deviations from the spectral index and its running depend on the space–space noncommutativity length scale.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
