In this study, we describe a novel method for one-step cloning and targeted duplication of P. ananatis chromosomal fragments. According to this method, the chromosomal region of interest is subcloned in vivo via λ Red recombination into the short synthetic non-replicable DNA fragment containing the excisable antibiotic-resistance marker gene and φ80 att-P site.

We present measurements of the cross section and double-helicity asymmetry A_{LL} of direct-photon production in p[over →]+p[over →] collisions at sqrt[s]=510  GeV. The measurements have been performed at midrapidity (|η|<0.25) with the PHENIX detector at the Relativistic Heavy Ion Collider.

Article Synopsis
  • L-serine biosynthesis starts with D-3-phosphoglycerate being converted into 3-phosphohydroxypyruvate by the enzyme SerA, which can also produce D-2-hydroxyglutarate (D-2-HGA) from 2-ketoglutarate.
  • Recent discoveries have identified bacterial enzymes called D2HGDHs that convert D-2-HGA back to 2-ketoglutarate; however, little is known about these enzymes in certain bacterial families.
  • Two novel D2HGDHs were characterized, revealing their substrate specificity, optimal pH conditions, and sensitivity to metal ions, suggesting their potential use in metabolic engineering for creating microbes with specific traits.

The study of nuclei and antinuclei production has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. The first measurement of the production of _{Λ}^{3}H in p-Pb collisions at sqrt[s_{NN}]=5.02  TeV is presented in this Letter.

Employing classical isothermal molecular dynamics, we simulated coalescence of mesoscopic Au nanodroplets, containing from several thousands to several hundred thousands of atoms, and sintering of mesoscopic solid Au nanoparticles. For our atomistic simulations, we used the embedded atom method. The employed open access program large-scale atomic/molecular massively parallel simulator makes it possible to realize parallel graphical processing unit calculations.
