Longitudinal epiphyseal bracket [PDF]

Journal of Children's Orthopaedics, 2013
Longitudinal epiphyseal bracket or bracket epiphysis is an uncommon disorder of growth. Alternatively known as a delta phalanx, it is due to an anomalous secondary ossification center that extends longitudinally along the diaphysis. Although rare, longitudinal epiphyseal bracket most commonly manifests in the hands as clinodactyly and in the feet as ...

Biquandle bracket quivers

Journal of Knot Theory and Its Ramifications, 2023
Biquandle brackets define invariants of classical and virtual knots and links using skein invariants of biquandle-colored knots and links. Biquandle coloring quivers categorify the biquandle counting invariant in the sense of defining quiver-valued enhancements which decategorify to the counting invariant.

Robot cable-compliant devices [PDF]

, 1990
A cable compliant robotic joint includes two U configuration cross section brackets with their U cross sections lying in different planes, one of their brackets being connected to a robot arm and the other to a tool.

Classification and Casimir Invariants of Lie-Poisson Brackets

, 1999
We classify Lie-Poisson brackets that are formed from Lie algebra extensions. The problem is relevant because many physical systems owe their Hamiltonian structure to such brackets. A classification involves reducing all brackets to a set of normal forms,

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.

Comparison of the Conventional and Laser Etching on the Bonding of the Orthodontic Brackets: An Original Research

Journal of Pharmacy and Bioallied Sciences
Background: Acid etching enamel improves resin–enamel adhesion and adhesive characteristics, but has pros and cons. The effects of laser etching on the bonding of orthodontic brackets vary depending on the wavelength, power output, exposure duration, and

Motivational Goal Bracketing [PDF]

SSRN Electronic Journal, 2009
It is a puzzle why people often evaluate consequences of choices separately (narrow bracketing) rather than jointly (broad bracketing). We study the hypothesis that a present-biased individual, who faces two tasks, may bracket his goals narrowly for motivational reasons.

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

Laser Applications in Metal Orthodontic Bracket Debonding: A Systematic Review

Applied Sciences
Objective: The aim of this systematic review was to evaluate the effectiveness and safety of various laser wavelengths for debonding orthodontic metal brackets compared to traditional plier-based methods. The primary outcomes assessed were enamel damage,

Gauged Lie-Poisson structures [PDF]

, 1984
A global formula for Poisson brackets on reduced cotangent bundles of principal bundles is derived. The result bears on the basic constructions for interacting systems due to Sternberg and Weinstein and on Poisson brackets involving semi-direct products
