Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Unpredictable Root Canal Morphology: Expect the Unexpected

Advances in Human Biology, 2015
Background: A maxillary first molar with more than four canals is an interesting example of anatomic variations, especially when two of these canals are detected, with separate apical foramen in the distal root.

Sol–Gel Thin Films for the Protection of Ancient Glass Artifacts: A Performance Comparison Between Inorganic and Hybrid Silica Compositions

Advanced Materials Interfaces, EarlyView.
This study explores the development of sol–gel coatings for archaeological glass conservation. By formulating silica‐based solutions with low acid concentrations and applying them via dip coating, protective films are prepared at room temperature. Analysis reveals that hybrid coatings with methyl and octyl groups provide superior protection against ...

The relation between parameter curves and lines of curvature on canal surfaces [PDF]

arXiv, 2012
A canal surface is the envelope of a moving sphere with varying radius, defined by the trajectory C(t) (spine curve) of its center and a radius function r(t). In this paper, we investigate when parameter curves of the canal surface are also lines of curvature. Last of all, for special spine curves we obtain the radius function of canal surfaces.

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

Advanced Materials Technologies, EarlyView.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

Ultrastructural analysis of uninstrumented root canal areas following various irrigation regimens [PDF]

Stomatološki glasnik Srbije, 2016
Introduction During endodontic treatment smaller or larger areas of root canal wall remain non-instrumented. This can affect prognosis of endodontic treatment as some bacteria may be left behind.

Stratification and enumeration of Boolean functions by canalizing depth [PDF]

arXiv, 2015
Boolean network models have gained popularity in computational systems biology over the last dozen years. Many of these networks use canalizing Boolean functions, which has led to increased interest in the study of these functions. The canalizing depth of a function describes how many canalizing variables can be recursively picked off, until a non ...

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

Advanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.
