Over the last few years, there have been numerous discussions on the American Society for Microbiology’s clinical listservs (DivC, and ClinMicroNet) regarding sterility testing of cell and gene therapy products and environmental monitoring and gloved fingertip testing for hospital pharmacies. Clinical microbiology laboratories have often been asked to assist with testing due to the on-site proximity of laboratory equipment and microbiological expertise within the hospital environment. The role of the clinical microbiology laboratory in this setting, however, is questionable due to major differences in test requirements and regulatory oversight. Here, we provide a side-by-side comparison of clinical versus current good manufacturing practices microbiology laboratories to provide guidance to those that are currently assisting with or have been asked to assist with sterility testing of manufactured biopharmaceutical products that have become common frontline treatments in modern medicine.

Serious wear phenomena occur in mining machinery under complex working conditions, and the wear of machine parts is primarily caused by the synergistic effect of adhesive wear, abrasive wear, corrosive wear, etc. However, the existing friction and wear testing equipment cannot be used to carry out wear tests under complex working conditions. To simultaneously meet the test requirements of adhesive wear, abrasive wear, and corrosive wear, a novel sliding friction and wear tester that can simulate complex working conditions was developed in the present research. The tester is composed of a loading mechanism, a speed-regulating mechanism, a corrosion chamber, and a control and display system. Wear tests of the middle plate of a scraper conveyor, a key equipment of coal mining, were carried out to verify the consistency and effectiveness of the tester. The test results were consistent, and those under the same test conditions were similar with a maximum standard deviation of 2.4 mg. The wear condition of the middle plate specimens was close to the actual wear condition of the middle plate. Moreover, the surfaces of the middle plate specimens after grinding exhibited obvious adhesive, abrasive, and corrosive wear characteristics, and the wear degrees of the specimens under the same test conditions were similar. The quality loss of the middle plate specimens was found to increase with the increase of coal gangue percentage, and the main wear mechanism was the synergistic action of abrasive, adhesive, and corrosive wear.

Recently a number HVdc circuit breakers (CBs) based on various dc current interruption principles have been developed and a few are put in operation. However, due to a lack of practical experience, no clearly defined requirements that the HVdc CBs should satisfy exist. To define and refine justified test requirements, a thorough understanding of the interactions between the internal components of the HVdc CB and the stresses on these components under real dc fault current interruption condition is necessary. In this paper, an experimental dc CB based on the active current injection technique is setup in a high-power laboratory to investigate the performances of the main components; namely, the vacuum interrupter (VI) and the metal oxide surge arrester (MOSA). The performances of three different designs VIs are investigated and it is found out that each of the VIs behave completely different. The key parameters having impact on current interruption performance of the VIs are identified and analyzed in detail. Moreover, the performance of a MOSA, designed for HVdc CB application, is also investigated by applying energy per volume ranging between $\text{70}\!-\!\text{220}\;\text{J/}\text{cm}^\text{3}$ at temperature as high as $\text{250}$ °C. In order to find out the performance limit of the MOSA for this application, successive high-energy tests are performed until electro-mechanical failures occur in the MO varistors. Various failure modes such as fracturing and puncture are observed. The detailed analysis of these failure mechanisms during destructive tests and the root causes are presented.

Tuberculosis (TB) is an infectious disease that threatens >10 million people annually. Despite advances in TB diagnostics, patients continue to receive an insufficient diagnosis as TB symptoms are not specific. Many existing biodiagnostic tests are slow, have low clinical performance, and can be unsuitable for resource‐limited settings. According to the World Health Organization (WHO), a rapid, sputum‐free, and cost‐effective triage test for real‐time detection of TB is urgently needed. This article reports on a new diagnostic pathway enabling a noninvasive, fast, and highly accurate way of detecting TB. The approach relies on TB‐specific volatile organic compounds (VOCs) that are detected and quantified from the skin headspace. A specifically designed nanomaterial‐based sensors array translates these findings into a point‐of‐care diagnosis by discriminating between active pulmonary TB patients and controls with sensitivity above 90%. This fulfills the WHO's triage test requirements and poses the potential to become a TB triage test., A noninvasive method for tuberculosis (TB) detection from skin is introduced in this paper. The method harnesses nanomaterial‐based sensors that are sensitive to patterns of volatile biomarkers that are linked with the illness. The results present TB‐related changes in the pattern with above 90% sensitivity detecting active TB patients with the sensors, demonstrating the potential to evolve into a new TB triage test.

This paper provides an approach for selective black-box model-based regression testing for web applications, emphasizing testing proper mitigation of external failures in web applications. This approach uses an existing model of web applications, FSMWeb, and extends its test generation capabilities to include selective regression testing of fail-safe behavior. It classifies existing tests as reusable, retestable, and obsolete. The approach reduces the number of tests compared to a full retest between 3% to 81% depending on the type of changes in the example and by over 99% in the case study. Removing reusable requirements reduced test requirements between 49% to 65% in the case study. The approach also uses partial regeneration for new tests wherever possible.

We introduce a distributed control method for coordinating multiple vehicles in the framework of an automated valet parking (AVP) system. The control functionality is distributed between an infrastructure server, called parking area management (PAM) system, and local autonomous vehicle control units. Via a vehicle-to-infrastructure (V2I) communication interface, model predictive control (MPC) decisions of the vehicles are shared with the coordination unit in the PAM. This unit in turn computes a coupling feedback which is shared with the vehicles. The control system is integrated in an automated test-system to cope with the high test requirements and short development cycles of highly automated systems. Evaluations conducted with the test-system show the functionality of the proposed distributed control method for multi-vehicle coordination. Results indicate safe coordination, and an efficiency increase compared to an uncoordinated method in an AVP simulation environment.

The integration of HVDC GIS equipment into offshore wind converter station may also comprise a HVDC GIS cable connection assembly. For HVDC cable systems test requirements are already existing and are successfully applied in the industry. When suggesting testing methods for an interface device, such as the DC cable connection assembly, the differences need to be considered. This paper describes the different test philosophies in the suggested HVDC GIS dielectric testing and existing HVDC cable system testing. The electric field profiles are compared in an exemplified HVDC cable termination under different load conditions and are related to executed qualification tests according to the testing philosophy of HVDC cable systems. The resulting differences due to the different testing philosophies are discussed. This work may serve as input to the discussion of testing approaches for equipment at the interface between DC gas-insulated equipment and HVDC cables

International audience; Endocrine-disrupting chemicals (EDCs) substantially cost society as a result of increases in disease and disability but—unlike other toxicant classes such as carcinogens—have yet to be codified into regulations as a hazard category. This Series paper examines economic, regulatory, and policy approaches to limit human EDC exposures and describes potential improvements. In the EU, general principles for EDCs call for minimisation of human exposure, identification as substances of very high concern, and ban on use in pesticides. In the USA, screening and testing programmes are focused on oestrogenic EDCs exclusively, and regulation is strictly risk-based. Minimisation of human exposure is unlikely without a clear overarching definition for EDCs and relevant pre-marketing test requirements. We call for a multifaceted international programme (eg, modelled on the International Agency for Research in Cancer) to address the effects of EDCs on human health—an approach that would proactively identify hazards for subsequent regulation.

The current implementation of automated mobile apps testing generally relies on internal program information, such as reading code or GUI layout files, capturing event streams. This paper proposes an approach of automated mobile apps testing from a completely visual perspective. It uses computer vision technology to enable computer to judge the internal functions from the external GUI information of mobile apps as we humans do and generates test strategy for execution, which improves the interactivity, flexibility, and authenticity of testing. We believe that this vision-based testing approach will further help alleviate the contradiction between the current huge test requirements of mobile apps and the relatively lack of testers.
