Robot‐Assisted Doppler Optical Coherence Tomography for Intraoperative Evaluation of Microvascular Anastomoses

Advanced Intelligent Systems, EarlyView.
This work presents a robot‐assisted Doppler optical coherence tomography system for autonomous, wide‐field intraoperative assessment of microvascular anastomoses. Machine‐vision–guided probe positioning and adaptive scan planning enable three‐dimensional structural and hemodynamic imaging over extended vessel segments.

Entropy‐Guided Convolutional Neural Network Classification of Sensor Signals for Real‐Time Surface Quality Monitoring in Direct Laser Interference Patterning

Advanced Intelligent Systems, EarlyView.
Neural‐network pipeline for real‐time DLIP surface‐quality monitoring: spectral entropy of WLI topographies is used to generate interpretable K‐means labels, which are transferred to time‐resolved photodiode traces. A compact dual‐input 1D‐CNN (signal + laser parameters) learns discriminative spatiotemporal features and predicts “OK/NOK” surface ...

VIBRATION EXPERIMENT OF COAL SHEARER CUTTING UNIT GEARBOX HOUSING IN OBLIQUE CUTTING

Jixie qiangdu, 2020
Oblique cutting is a working condition in fully mechanized mining whose main task is making it possible for long wall shearer to cut the coal seam,and it is a harsh working condition since the shearer is forced to be bent.

Pore morphology changes and quantitative analysis and evaluation of high‐rank coal samples after impact

Energy Science & Engineering
The influencing mechanism of impact loads on the pore morphology of high‐rank coal has been extensively investigated since mining safety is greatly determined by the ensuing state of gas occurrence.

Investigation of Hexagonal Honeycomb Topology for Impact Optimization in Energetic Material

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The regulation of the mechanical properties of energetic materials manufactured by traditional processes is constrained. However, the introduction of lattice structures can facilitate the regulation of mechanical properties without necessitating alterations to the materials themselves. Using finite element analysis and experimental validation,

Evaluation of Mechanical Properties of Phase‐Separated Cellulose Filler/Poly(Lactic Acid)/Elastomer Composites via Microstructure‐Informed Physics Simulation and In Situ Synchrotron X‐Ray Micro‐CT

Journal of Applied Polymer Science, EarlyView.
Phase‐separation microstructure and mechanical properties of a ternary biocomposite evaluated by integrated AFM, AFM‐informed FEM, and in situ X‐ray CT. ABSTRACT This study investigates phase‐separated cellulose filler/poly(lactic acid) (PLA)/elastomer ternary composites to enhance the mechanical performance of bioplastics. Atomic force microscopy (AFM)

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

The Anatomical Record, EarlyView.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Effect of Oblique Impact Angles on Fracture Patterns in Laminated Glass Plates Impacted by a 10 mm Steel Ball

Applied Sciences
Many studies have examined normal impacts on glass, but data on oblique impacts are limited, and, in particular, there is very limited experimental data on oblique impacts at various angles under consistent experimental conditions.
