Modified band and loop space maintainer: Mayne's space maintainer

open access: yesInternational Journal of Pedodontic Rehabilitation, 2018
Primary teeth play a pivotal role in preventing malocclusion of permanent dentition. When there is premature tooth loss, the space should be maintained for preserving the arch form and preventing space loss. Space maintainer is the treatment of choice in such conditions. When the conventional method is not applicable, we plan for modifications. In this

Nonlinear looped band structure of Bose-Einstein condensates in an optical lattice

open access: yes, 2016
We study experimentally the stability of excited, interacting states of bosons in a double-well optical lattice in regimes where the nonlinear interactions are expected to induce "swallowtail" looped band structure.

Quantum Waveguide Transport in Serial Stub and Loop Structures [PDF]

open access: yes, 1994
We have studied the quantum transmission properties of serial stub and loop structures. Throughout we have considered free electron networks and the scattering arises solely due to the geometric nature of the problem.

Clinical evaluation of chairside band and loop space maintainers [PDF]

open access: yesEgyptian Orthodontic Journal, 2013
The use of space maintainer in the pediatric population has gained increasing attention from researchers. Chairside space maintainers are single setting technique and they are able to save practice time. The purpose of the study was to compare the clinical performance of chairside and conventional band and loop space maintainers.

Adiabatic quantum pumping in an Aharonov-Bohm loop and in a Si-like nanowire: Role of interference in real space and in momentum space

open access: yes, 2007
We study the consequences of interference effects on the current generated by adiabatic quantum pumping in two distinct one-dimensional (1D) lattice model. The first model contains an Aharonov-Bohm (AB) loop within a tight-binding chain of lattice sites.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

The PRIMA fringe sensor unit [PDF]

open access: yes, 2009
The Fringe Sensor Unit (FSU) is the central element of the Phase Referenced Imaging and Micro-arcsecond Astrometry (PRIMA) dual-feed facility and provides fringe sensing for all observation modes, comprising off-axis fringe tracking, phase referenced ...

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

The Longevity of Band and Loop and Pontic–Crown Fixed Space Maintainers in Children Aged 4 to 7 Years: A Randomized Controlled Trial

open access: yesDental Hypotheses, 2018
Introduction: The best way to prevent malocclusion and reduce the length of the arch in cases of early loss of primary teeth is placement of space maintainer.

Space Maintainers in Dentistry: Past to Present [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2013
Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic ...
