NLO PDFs from the ABMP16 fit [DESY-18-026; DO-TH 17/28; arXiv:1803.07537]   We perform a global fit of parton distribution functions (PDFs) together with the strong coupling constant $\alpha_s$ and the quark masses $m_c$, $m_b$ and $m_t$ at next-to-leading order (NLO) in QCD. The analysis applies the $\overline{\mathrm{MS}}\,$ renormalization scheme for $\alpha_s$ and all quark masses.

The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using the data collected with the CMS detector in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$.

These compounds exert structuring effects on the cellular membrane organization, regulate the gene expression, and modulate various signaling cascades and metabolic processes [...] OpenAccess: PDF PDF (PDFA); 2018-03-1812:23 [PUBDB-2018-01498] Journal Article et al The nervous and visual systems of onychophorans and tardigrades: learning about arthropod evolution from their closest relatives Journal of comparative physiology / A 203(8), 565 - 590 (2017) [10.1007/s00359-017-1186-4]   Understanding the origin and evolution of arthropods requires examining their closest outgroups, the tardigrades (water bears) and onychophorans (velvet worms). Despite the rise of molecular techniques, the phylogenetic positions of tardigrades and onychophorans in the panarthropod tree (onychophorans + tardigrades + arthropods) remain unresolved.

The many binding sites of hydantoin Physical chemistry, chemical physics 20(8), 5545 - 5552 (2018) [10.1039/C7CP06518C]   Prebiotic hydantoin and its complexes with one and two water molecules are investigated using high-resolution broadband rotational spectroscopy in the 2–8 GHz frequency range. The hyperfine structure due to the nuclear quadrupole coupling of the two $^{14}$N atoms is analysed for the monomer and the complexes.

We observed and analysed the rotational spectra of the ground state of the molecule and ten vibrationally excited states with energies between 180–500 cm$^{−1}$.

Compared to the conventional ∼ 0.8 or 1 $\mu$m near-infrared (IR) pulses, a ∼ 2  $\mu$m driver for intrapulse DFG can provide more efficient conversion into the wavelengths longer than 5 $\mu$m due to a lower quantum defect and is more suitable for the non-oxide nonlinear crystals that have a relatively low bandgap energy.

The excited-state absorption in the transient UV-visible spectra, associated with the 2,2'-bipyridine radical anion, provides a robust marker for the MLCT excited state, while the transient Kβ x-ray emission spectra provide a clear measure of intermediate and high spin metal-centered excited states.
