TL;DR: In this article, the authors analyzed the Newtonian equation with memory and the fractional generalization of this model is investigated and exact solutions within Caputo and Riemann-Liouville fractional derivatives are reported.
Abstract: In this study we analyzed the Newtonian equation with memory. One physical model possessing memory effect is analyzed in detail. The fractional generalization of this model is investigated and the exact solutions within Caputo and Riemann–Liouville fractional derivatives are reported.

TL;DR: In this article, the effects of temperature and relative sea level on decomposition rate and stabilization of organic matter (OM) in tidal wetlands worldwide were investigated. But the results showed that OM stabilization was lower in low, more frequently flooded vs. high, less frequently flooded zones.
Abstract: . Tidal wetlands, such as tidal marshes and mangroves, are hotspots for carbon
sequestration. The preservation of organic matter (OM) is a critical process
by which tidal wetlands exert influence over the global carbon cycle and at
the same time gain elevation to keep pace with sea-level rise (SLR). The
present study assessed the effects of temperature and relative sea level on
the decomposition rate and stabilization of OM in tidal wetlands worldwide,
utilizing commercially available standardized litter. While effects on
decomposition rate per se were minor, we show strong negative effects of
temperature and relative sea level on stabilization, as based on the fraction
of labile, rapidly hydrolyzable OM that becomes stabilized during deployment.
Across study sites, OM stabilization was 29 % lower in low, more frequently
flooded vs. high, less frequently flooded zones. Stabilization declined by
∼ 75 % over the studied temperature gradient from 10.9 to
28.5 ∘C . Additionally, data from the Plum Island long-term
ecological research site in Massachusetts, USA, show a pronounced reduction in
OM stabilization by > 70 % in response to simulated coastal
eutrophication, confirming the potentially high sensitivity of OM
stabilization to global change. We therefore provide evidence that rising
temperature, accelerated SLR, and coastal eutrophication may decrease the
future capacity of tidal wetlands to sequester carbon by affecting the
initial transformations of recent OM inputs to soil OM.

TL;DR: In this paper, the authors report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April 1 and August 10, including the first detailed characterization of the synchrotron peak with Swift and NuSTAR.
Abstract: We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April 1 and August 10, including the first detailed characterization of the synchrotron peak with Swift and NuSTAR. During the campaign, the nearby BL Lac object was observed in both a quiescent and an elevated state. The broadband campaign includes observations with NuSTAR, MAGIC, VERITAS, the Fermi Large Area Telescope, Swift X-ray Telescope and UV Optical Telescope, various ground-based optical instruments, including the GASP-WEBT program, as well as radio observations by OVRO, Metsahovi, and the F-Gamma consortium. Some of the MAGIC observations were affected by a sand layer from the Saharan desert, and had to be corrected using event-by-event corrections derived with a Light Detection and Ranging (LIDAR) facility. This is the first time that LIDAR information is used to produce a physics result with Cherenkov Telescope data taken during adverse atmospheric conditions, and hence sets a precedent for the current and future ground-based gamma-ray instruments. The NuSTAR instrument provides unprecedented sensitivity in hard X-rays, showing the source to display a spectral energy distribution (SED) between 3 and 79 keV consistent with a log-parabolic spectrum and hard X-ray variability on hour timescales. None (of the four extended NuSTAR observations) show evidence of the onset of inverse-Compton emission at hard X-ray energies. We apply a single-zone equilibrium synchrotron self-Compton (SSC) model to five simultaneous broadband SEDs. We find that the SSC model can reproduce the observed broadband states through a decrease in the magnetic field strength coinciding with an increase in the luminosity and hardness of the relativistic leptons responsible for the high-energy emission.
