Preparation of High-Viscosity Polypropylene Ultrafine Fiber Membranes by Centrifugal Spinning with Synergistic Jet-Guided and Cyclone-Assisted Stretching

工程科学与技术
ObjectiveUnstable melt feeding, severe splashing, and insufficient fiber stretching during centrifugal spinning of high-viscosity polymers considerably limit fiber quality and process continuity.

AI‐Assisted Morphometric Analysis and Molecular Phylogeny for a Dactylogyrid (Monopisthocotyla) Skin Parasite of an Ornamental Crenuchid Fish From Brazil

Acta Zoologica, EarlyView.
ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.

Re-intervention Utility After Endoscopic Ultrasound-Guided Hepaticogastrostomy Using a Partially Covered Stent with Anchoring Flange

Digestive Diseases and Sciences
Abstract Background and Aim: A long self-expandable metal stent (SEMS) with a sufficient intragastric portion is typically preferred for endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS). However, this type of stent can complicate endoscopic re-intervention for recurrent biliary obstruction (RBO).

Finite Element Analysis of Dentoalveolar Stress in Combat Sports Using Hybrid and Conventional Mouthguards

Dental Traumatology, EarlyView.
ABSTRACT Aim This study aimed to contribute to the development of modern mouthguards by evaluating the stresses generated by hook and uppercut punches applied during combat sports on dentoalveolar structures and mouthguards, the protective effectiveness of different mouthguard designs, and the resulting deformations using three‐dimensional finite ...

A novel technique for managing infected mandibular reconstruction plates with 3D printed guide flange prostheses

Oral Oncology Reports
The technique explores an innovative application of 3D printing technology in the creation of a guide flange prosthesis for a patient who had undergone hemi-mandibulectomy and was experiencing complications due to an infected mandibular reconstruction plate.

Comparison of Mesoscale Crack Advance and Process Zone Element Approaches for Simulating Ductile Crack Trajectories in Steel

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Rigorous application of continuum damage mechanics (CDM) models coupled with crack propagation schemes can predict crack branching or zigzag trajectories near the crack tip, even when the macroscopic crack growth is straight. This arises from oscillations in the local damage field and is consistent with experimental observations of ductile ...

Fatigue Assessment of Welded Joints Subjected to Multiaxial Loading Conditions through the Effective Critical Plane Approach

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Reliable fatigue design of welded components under multiaxial loading demands local criteria able to capture both the stress gradient at the weld notches and the influence of a complex loading condition including non proportionality of the stress‐strain load history. The Effective Critical Plane (ECP) approach, based on a stress averaging over

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Uncoupled multimodal wave reflection from guide termination with different flanges: Experimental and numerical investigation

Acta Acustica
Reflection of propagating modes is studied at the exit of a cylindrical acoustic wave guide from both an experimental and a numerical point of view. The plane mode and several purely azimuthal higher modes are extracted by means of modal decomposition and the uncoupled reflection coefficients of each mode are obtained using two microphonic antennas for

Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei)

Journal of Anatomy, EarlyView.
This article demonstrates that the teeth and rostral denticles of an extinct clade of sawfish‐like skates display an extremely derived enameloid microstructure, similar to what is known among sharks. The presence of tooth‐like enameloid microstructure in dermal denticles opens new perspectives about the origins and development of chondrichthyan ...
