Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

open access: yesHigh Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Research Progress on Electrical Insulation Under Superimposed Voltage With High‐Frequency Harmonics in New‐Type Power Systems

open access: yesHigh Voltage, EarlyView.
ABSTRACT A new‐type power system serves as a critical technical support for the integration of new energy, and its secure and stable operation is of great importance. However, the extensive utilisation of power electronic devices leads to power equipment insulation being subjected to electrical stresses of high‐frequency harmonics, which can easily ...

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

open access: yesIntegrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

open access: yesIntegrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.

What Outcomes Matter in Vital Pulp Therapy? Current Concepts and Challenges

open access: yesAustralian Dental Journal, EarlyView.
ABSTRACT Vital pulp therapy (VPT) has re‐emerged as a practical and biologically sound alternative for managing deep caries and carious pulp exposures. Although its clinical use is now widespread, the outcomes used to judge the success of VPT remain inconsistent and often difficult to compare across studies.

Biocompatibility With Osteogenic Potential of Premixed Bioceramic Cements for Use in Apical Surgery

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study investigated the biocompatibility and osteogenic potential of premixed bioceramic cements (PBCs)—CeraPutty, EndoCEM MTA Premixed, Well‐Root PT, and One‐Fil PT Injectable—as alternatives to mineral trioxide aggregate for retrograde filling in endodontic microsurgery.

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...

Influence of Delivery Method of Hydraulic Calcium Silicate Cement‐Based Sealer on Void Formation: A Micro‐Computed Tomography Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to compare three delivery methods of a hydraulic calcium silicate cement‐based sealer by quantifying voids using the single‐cone technique. Forty‐eight human mandibular molars were instrumented and scanned using micro‐computed tomography.

Effect of Kinematics and Speed on Filling Material Removal, Canal Transportation, and Apical Extrusion During Retreatment of Curved Canals

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the effects of kinematics (reciprocating vs. continuous rotation) and rotational speed (350 vs. 1200 rpm) on filling removal, canal transportation, and apical extrusion during retreatment of curved root canals. Vertucci type II mesial roots of mandibular molars were prepared, filled, and scanned by micro‐computed ...
