The Institutional Repositories Working Group of the Spanish Network of University and CSIC Li-braries (REBIUN, https://www.rebiun.org/grupos-trabajo/repositorios) is working on implementingthe openCOST metadata schema as there is an interest in showing information about open accesspublishing costs in a commonly agreed way. The analysis and beta implementation of the metadataschema is being advanced by the DSpace repositories subgroup and ongoing work has focused onidentifying the most relevant metadata given the data model in place in such repositories as wellas the type and granularity of OA publishing cost information collected by their institutions.

Im Netzwerk spanischer wissenschaftlicher Bibliotheken (Red de BibliotecasUniversitarias y Científicas Españolas, REBUIN) haben sich die 76Universitätsbibliotheken des Landes und die Bibliotheken des Oberster Rat fürwissenschaftliche Forschung (Consejo Superior de Investigaciones Científicas,CSIC), der größten Forschungseinrichtung Spaniens zusammengeschlossen. Um OpenAccess Kosten trotz der diversen Ausrichtung einheitlich zu erfassen unddarzustellen hat die Arbeitsgruppe „Institutional Repositories“ von REBUINbegonnen openCost für alle beteiligten Einrichtungen zu implementieren. [...]

The high global warming potential of CH4 makes the catalytic conversion of residual CH4 in exhaust gases vital for applications such as CH4 combus tion engines and turbines, power-to-gas or biomass plants. The most active heterogeneous catalyst system for complete CH4 oxidation at low temper atures (< 650K) in lean reaction gas mixtures (overstoichiometric oxygen content) is the class of Pd-based catalysts supported by (mixed) metal oxide supports. [...]

We investigate the combination of a two-level sampling algorithm with distillation techniques to compute disconnected fermionic correlation functions. The method relies on a factorization of the quark propagator into domain-local contributions that depend only on the gauge fields within overlapping temporal regions, enabling independent submeasurements of each term through a two-level sampling strategy. [...]

Dense plasma environment affects the electronic structure of ions via variations of the microscopic electrical fields, also known as plasma screening. This effect can be either estimated by simplified analytical models, or by computationally expensive and to date unverified numerical calculations. [...]

The functionalization of surfaces with therapeutically applicable nucleic acid carriers provides promising strategies in biomedical research to develop therapies that focus on local nucleic acid delivery. One such approach is the embedding of lipoplexes (LPXs) in polysaccharide-based polyelectrolyte multilayers (PEMs). [...]

The first measurement of the jet axis decorrelation in events with jets recoiling from an isolated photon is presented for lead-lead (PbPb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The jet axis decorrelation is the angular difference ($Δ{j}$) between two definitions of the jet axis. [...]

Event shape variables, constructed from the four-momenta of the final-state objects in an event, are sensitive to the predictions of quantum chromodynamics in multijet production. A measurement of five event shape variables is presented, using proton-proton collision data collected at a centre-of-mass energy of 13 TeV with the CMS detector during 2016$-$2018, corresponding to an integrated luminosity of 138 fb$^{-1}$. [...]

The azimuthal anisotropy of prompt D$^\pm_\mathrm{s}$ mesons produced in lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is measured using data obtained with the CMS detector. The dataset corresponds to an integrated luminosity of 0.58 nb$^{-1}$. [...]
