Improvements of a Failure Database for Marine Diesel Engines Using the RCM and Simulations

Energies, 2019
Diesel engines are widely used in marine transportation as a direct connection to the propeller and as electrical principal or auxiliary generator sets. The engine is the most critical piece of equipment on a vessel platform; therefore, the engine’ ...

Anatomic Transtibial Tunnel Placement Using an Initial 6‐mm Drill Bit for Anterior Cruciate Ligament Reconstruction

Arthroscopy Techniques, EarlyView.
Abstract Precise anatomic tunnel placement is essential for restoring native knee biomechanics and minimizing graft failure in anterior cruciate ligament reconstruction. We describe a tibial tunnel drilling technique designed to enhance tunnel placement accuracy, reduce intra‐articular trauma, and preserve native tibial footprint remnants when ...

A Hoveyda–Grubbs‐Type Olefin Metathesis Catalyst Bearing a Fluorinated Unsymmetrical NHC Ligand

European Journal of Inorganic Chemistry, EarlyView.
A fluorinated unsymmetrical NHC ruthenium complex was synthesised and employed as a catalyst for olefin metathesis reactions. The modification of the steric and electronic properties of the NHC ligand through the introduction of fluorine substituents results in improved activity but lower selectivity compared to the analogous non‐fluorinated NHC ...

Responsive stimulation of the thalamus for idiopathic generalized epilepsy: Results of the randomized controlled NAUTILUS trial through 18 months

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to evaluate the safety and effectiveness of responsive thalamic stimulation as adjunctive therapy for drug‐resistant idiopathic generalized epilepsy (IGE) with generalized tonic–clonic seizures (GTCSs). Methods NAUTILUS is a prospective, multicenter, single‐blind, randomized sham‐controlled pivotal trial ...

Designing Orthogonal‐Arc Trajectories for Horizontal Wells to Reduce Drilling Cost in Development of Shale Oil/Gas Reservoirs

Energy Science &Engineering, EarlyView.
Designing 3‐dimensional (3D) horizontal well trajectories is critical for enhancing drilling efficiency in shale reservoirs. This paper proposes an innovative Orthogonal‐Arc Trajectory (OAT) for 3D horizontal wells, which employs a single constant curvature in the curved section.

Design of a Physical Layer Encryption Scheme for Rate Compatible Modulation

IEEE Access, 2020
Spectral efficiency and transmission security are both essential metrics for wireless communication. Rate compatible modulation (RCM) is an adaptive transmission scheme to improve the spectral efficiency. However, the mapping matrix of RCM is fixed. Once

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

Food Chemistry International, EarlyView.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%
