External quality assessment (EQA) of Neisseria gonorrhoeae antimicrobial susceptibility testing in primary laboratories in Germany

open access: yesBMC Infectious Diseases, 2020
Worldwide, an increase in antimicrobial resistance (AMR) of Neisseria gonorrhoeae has been observed. Until now, no protocol for an external quality assessment (EQA) has been available for Germany.

Quasi-Particle Theory of Shear and Bulk Viscosities of Hadronic Matter

open access: yes, 2010
A theoretical framework for the calculation of shear and bulk viscosities of hadronic matter at finite temperature is presented. The framework is based on the quasi-particle picture.

Semantic Bidirectionalization Revisited [PDF]

open access: yes, 2014
A bidirectional transformation is a pair of mappings between source and view data objects, one in each direction. When the view is modified, the source is updated accordingly with respect to some laws.

Multicenter external quality assessment program for PCR detection of Mycobacterium ulcerans in clinical and environmental specimens.

open access: yesPLoS ONE, 2014
BackgroundMycobacterium ulcerans is the causative agent of Buruli ulcer (BU), a necrotizing disease of the skin, soft tissue and bone. PCR is increasingly used in the diagnosis of BU and in research on the mode of transmission and environmental reservoir

Large Language Model‐Based Chatbots in Higher Education

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of large language models (LLMs) in higher education can facilitate personalized learning experiences, advance asynchronized learning, and support instructors, students, and researchers across diverse fields. The development of regulations and guidelines that address ethical and legal issues is essential to ensure safe and responsible adaptation

Viscosity coefficients for hadron and quark-gluon phases

open access: yes, 2010
The shear ($\eta$) and bulk ($\zeta$) viscosities are calculated in a quasiparticle relaxation time approximation. The hadron phase is described within the relativistic mean field based model with scaled hadron masses and couplings.

Combined Dip‐Coating and Spray Coating Techniques for Modifying PVDF Membranes With PDMS and TiO2 for Photocatalytic Membrane Distillation

open access: yesJournal of Applied Polymer Science, EarlyView.
Main steps of membrane modification to impart hydrophobic character and its characterization for photocatalytic vacuum membrane distillation. ABSTRACT Membrane modification or functionalization techniques are widely studied to develop membranes with tailored properties for specific applications. This work investigates the combination of two methods—dip‐

An efficient high-order Nystr\"om scheme for acoustic scattering by inhomogeneous penetrable media with discontinuous material interface [PDF]

open access: yes, 2015
This text proposes a fast, rapidly convergent Nystr\"{o}m method for the solution of the Lippmann-Schwinger integral equation that mathematically models the scattering of time-harmonic acoustic waves by inhomogeneous obstacles, while allowing the ...
