Friction Surfacing Cladding (FSC) is a relatively new solid state process to deposit thin metallic clad layers on substrates. It employs a hollow rotating tool that supplies the clad material. Frictional and viscous heating take place that soften the clad material and enhance the bonding of the clad material to the substrate. Thin layers of commercially pure aluminium can be deposited well on a...

Double-clad photonic crystal fiber and double-clad fiber have been widely used in multiphoton-excited fluorescence or second-harmonic generation (SHG) endoscopy. We provide a useful comparison of two fibers used in nonlinear optical microendoscopy. While a double-clad fiber is found to have a higher percentage of the output power from its core, which results in the efficient utilization of the ...

PURPOSE OF REVIEW Chronic lung allograft dysfunction (CLAD) was recently introduced as an overarching term covering different phenotypes of chronic allograft dysfunction, including obstructive CLAD (bronchiolitis obliterans syndrome), restrictive CLAD (restrictive allograft syndrome) and graft dysfunction due to causes not related to chronic rejection. In the present review, we will highlight t...

BACKGROUND Bronchiolitis obliterans syndrome (BOS) with small-airway pathology and obstructive pulmonary physiology may not be the only form of chronic lung allograft dysfunction (CLAD) after lung transplantation. Characteristics of a form of CLAD consisting of restrictive functional changes involving peripheral lung pathology were investigated. METHODS Patients who received bilateral lung tr...

OBJECTIVES Living-donor lobar lung transplantation (LDLLT) has been established as a life-saving procedure for critically ill patients who cannot wait for cadaveric lung transplantation. Chronic lung allograft dysfunction (CLAD) is the main cause of late morbidity and mortality in lung transplantation. Studies on CLAD in cadaveric lung transplantation have been extensively reported, but few rep...

Friction stir processing (FSP) was used as a cladding method for the fabrication of a AA2024 clad layer on a AA1050 sheet. Crossover multi pass FSP with 50% overlap was considered as the cladding method. Effects of the number of FSP passes and post heat treatment on the microstructure and properties of clad layers were evaluated. Microstructural evolutions during the FSP and heat treatment were...

Continuous loop averaging deconvolution (CLAD) is one of the proven methods for recovering transient auditory evoked potentials (AEPs) in rapid stimulation paradigms, which requires an elaborated stimulus sequence design to attenuate impacts from noise in data. The present study aimed to develop a new metric in gauging a CLAD sequence in terms of noise gain factor (NGF), which has been proposed...
