Evaluation of flattening-filter-free and flattening filter dosimetric and radiobiological criteria for lung SBRT: A volume-based analysis

open access: yesFrontiers in Oncology, 2023
IntroductionThe use of volumetric modulated arc therapy (VMAT) with flattening-filter-free (FFF) beams is becoming more prevalent in lung cancer stereotactic body radiotherapy (SBRT).

Melt crystallization of PLA/Talc in fused filament fabrication

open access: yesMaterials & Design, 2019
The fused filament fabrication (FFF) process is characterized by fast local temperature decrease. Such characteristic usually leads to lower crystallinity degree in final printed parts when semi-crystalline polymers are used.

A Lucky Case of Successful Free Fibula Osteocutaneous Flap Harvest in Peronea Arteria Magna

open access: yesArchives of Plastic Surgery, 2022
The free fibula flap (FFF) is based on the peroneal artery (PA) system, and it is well known that several anatomical variations of the lower limb vascular system exist, including peronea arteria magna (PAM).

Multivariate Monitoring Workflow for Formulation, Fill and Finish Processes

open access: yesBioengineering, 2020
Process monitoring is a critical task in ensuring the consistent quality of the final drug product in biopharmaceutical formulation, fill, and finish (FFF) processes. Data generated during FFF monitoring includes multiple time series and high-dimensional

Comparative planning of flattening-filter-free and flat beam IMRT for hypopharynx cancer as a function of beam and segment number. [PDF]

open access: yesPLoS ONE, 2014
Although highly conformal dose distributions can be achieved by IMRT planning, this often requires a large number of segments or beams, resulting in increased treatment times.

n-3 fatty acids fed to ISA brown and Shaver white breeders and their female progeny during rearing: Impact on egg production, eggshell, and select bone attributes from 18 to 42 weeks of age

open access: yesPoultry Science, 2020
The impact of feeding sources of n-3 fatty acids (FA) to ISA brown and Shaver white breeders and their female offspring during rearing on egg production, eggshell, tibia, and keel bone attributes was examined.

Market opportunities seizing capability and fish farming firm performance: A dynamic managerial capability perspective

open access: yesHeliyon, 2023
The role that owner-managers’ managerial capabilities play in agricultural firms' strategic change and performance is still unclear. A firm's market opportunities seizing capability (OSC) is a source of competitiveness and superior performance.

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.
