An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Experimental investigation of fault reactivation mechanism and related seismic responses induced by hydraulic fracturing in mining areas

Meitan xuebao
Fault reactivation in mining areas can cause significant hazards, including rock bursts and mining-induced seismic events. Water injection and fracturing shows a great potential for fault reactivation regulation and seismicity mitigation.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Fault location method for hybrid MTDC system based on LCC signal injection strategy

Scientific Reports
A fault location method based on line commutation converter (LCC) signal injection strategy for hybrid multi-terminal direct current (MTDC) system is proposed to deter-mine the fault location after the permanent fault occurs and facilitate the line ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Assessing multi-version systems through fault Injection [PDF]

, 2001
Multi-version design (MVD) has been proposed as a method for increasing the dependability of critical systems beyond current levels. However, a major obstacle to large-scale commercial usage of this approach is the lack of quantitative characterizations ...

MEFISTO: A Series of Prototype Tools for Fault Injection into VHDL Models

, 2003
The early assessment of the fault tolerance mechanisms is an essential task in the design of dependable computing systems. Simulation languages offer the necessary support to carry out such a task. Due to its wide spectrum of application and hierarchical

Efficient Simulation of Structural Faults for the Reliability Evaluation at System-Level [PDF]

, 2010
In recent technology nodes, reliability is considered a part of the standard design ¿ow at all levels of embedded system design. While techniques that use only low-level models at gate- and register transfer-level offer high accuracy, they are too ...

Identify Silent Data Corruption Vulnerable Instructions Using SVM

IEEE Access, 2019
Silent data corruption (SDC) is the most insidious and harmful result type of soft error. Identify program vulnerable instructions (PVIns) that are likely to cause SDCs is extremely significant on selective software-based protection techniques.

Dynamic Sealing Behavior of Sand Self-Juxtaposition Windows on a Trap-Bounding Fault in a Natural Gas Storage Site

Lithosphere, 2022
An understanding of across-fault seals is essential for planning an injection/production strategy for a fault-bounded gas storage site. In addition, it is more likely to permit lateral leakage for a fault with sand self-juxtaposition windows.
