A new bracket system: Control 21™ Part II: Tooth movement

open access: yesAustralasian Orthodontic Journal, 2001
The Control 21™ bracket system has several attributes that overcome many of the friction, binding, notching and management problems encountered with other bracket systems.

Some observations regarding brackets and dissipation [PDF]

open access: yesarXiv
Some ideas relating to a bracket formulation for dissipative systems are considered. The formulation involves a bracket that is analogous to a generalized Poisson bracket, but possesses a symmetric component. Such a bracket is presented for the Navier-Stokes equations.

Direct Visualization and Quantitative Insights into the Formation and Phase Evolution of Cu Nanoparticles via In Situ Liquid Phase 4D‐STEM

open access: yesAdvanced Science, EarlyView.
By integrating in situ liquid phase transmission electron microscopy (LP‐TEM) with 4D scanning transmission electron microscopy (4D‐STEM), this work not only reveals the morphology and phase evolution of Cu nanoparticles during electrodeposition and electrooxidation processes but also demonstrates the possibility of mapping the grain size and phase ...

ASSESSMENT OF BRACKET BOND FAILURE DURING FIXED ORTHODONTIC TREATMENT BASED ON A QUESTIONNAIRE DISTRIBUTED TO ORTHODONTISTS

open access: yesRomanian Journal of Oral Rehabilitation
Introduction. The aim of this study was to evaluate the frequency of bracket bond failure and to identify the risk factors as well as the most frequently affected teeth. A secondary objective of the study was to establish whether white spot lesions (WSL),

Self‐Oscillation in Active Wires with Asymmetric Willis‐Type Viscosity

open access: yesAdvanced Science, EarlyView.
This study suggests a self‐oscillation strategy enabled by a new set of material parameters, namely the asymmetric Willis‐type viscosity, to bias and independently control oscillation mode shapes as well as frequencies. The exemplified active wire can benefit the development of autonomous materials to construct soft motors, agitators, pumps, and ...

Multivariate analyses of molecular genetic associations between childhood psychopathology and adult mood disorders and related traits

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, Volume 192, Issue 1-2, Page 3-12, January-March 2023., 2023
Abstract Ubiquitous associations have been detected between different types of childhood psychopathology and polygenic risk scores based on adult psychiatric disorders and related adult outcomes, indicating that genetic factors partly explain the association between childhood psychopathology and adult outcomes. However, these analyses in general do not

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

open access: yesAdvanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.
