Apical Extrusion of Debris Produced during Continuous Rotating and Reciprocating Motion

open access: yesThe Scientific World Journal, 2015
This study aimed to analyse and compare apical extrusion of debris in canals instrumented with systems used in reciprocating and continuous motion. Sixty mandibular premolars were randomly divided into 3 groups (n=20): the Reciproc (REC), WaveOne (WO ...

Genetic Algorithm for Space Debris and Space Objects Attitude Motion Reconstruction Through Optical Measurements [PDF]

open access: yes, 2023
Space debris has recently become a major problem in the planning and execution of space missions. Due to the recent widespread placement of satellite mega- constellations in Low Earth Orbits (LEO), where most of the catalogued debris is located, the need

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Lab‐Scale Fabrication Process Selection for Soft Robotics: Benchmarking, Tradeoffs, and Guidelines for Formative Manufacturing of Soft Silicone Components

open access: yesAdvanced Intelligent Systems, EarlyView.
Fabrication shapes soft robot performance, but benchmarking data and selection guidelines remain scarce. We fabricate silicone actuators using two molding techniques and three mold types, characterizing them with cycle testing, microscopy, profilometry, and 3D imaging. Applying our lab‐scale, soft robotics‐specific fabrication evaluation criteria shows

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

Structural compatibility between β‐lactams and substrate binding pockets of IMP‐1 and NDM‐1 determines the substrate spectrum

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Chemical structures of three β‐lactam classes and the substrate‐binding pockets (SBPs) of B1 metallo‐β‐lactamases (MBLs) were compared. Structural compatibility between β‐lactams and MBL SBPs correlates with enzymatic activity, providing insights into the substrate spectrum of MBLs and β‐lactam resistance.

Innovation of plant‐derived extracellular vesicles and interdisciplinary research: From discovery to biomedical applications

open access: yesBMEMat, EarlyView.
Plant‐derived extracellular vesicles offer numerous advantages and are regarded as highly promising candidates in the field of biomedicine. Abstract Extracellular vesicles (EVs) are double‐membrane vesicular structures that can be secreted by nearly all living cells.

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

open access: yesDeep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.
