R ecent epidemiologic surveys and studies have provided important information on the prevalence, extent, severity of periodontal diseases in United States. Over 50% adults had gingivitis an average 3 to 4 teeth. Subgingival calculus was present 67% population. Adult periodontitis, measured by presence pockets ≥ mm, found about 30% population Severe 6 mm were less than 5% Attachment loss 40% Gingival recession accounted for a significant amount attachment loss. The prevalence early‐onset...
W ith the increasing number of diabetics in an aging population and controversial research reports on relationship diabetes to periodontitis, clarification as a risk factor for periodontitis would be helpful. This review notes variations type, metabolic control, duration highlights results studies that have considered these variations. Diabetics who maintained reasonably good control had not lost more teeth or experienced periodontal attachment loss than non‐diabetics, although they pockets....
Prevalence, severity, and extent of periodontal diseases as well the role in tooth mortality are described for persons 19 years older U.S. 1981. The data were collected with a household probability sample non-institutionalized living contiguous 48 states. Plaque calculus scores six index teeth. All permanent teeth present capable being assessed scored gingivitis; pocket depths measured on mesial each probe. Examinations conducted by trained dentists calibrated specific criteria. Only 15%...
The purpose of this study was to determine the prevalence 5 periodontal pathogens in individuals with diabetes mellitus. Subjects (n = 107) 20-70 years age type 1 60) or 2 47) mellitus were studied for occurrence A. actinomycetemcomitans, F. nucleatum, E. corrodens, P. gingivalis and intermedia. Subgingival plaque sampled each subject from a single site exhibiting greatest inflammation. evaluation selected bacterial based on an immunoassay utilizing specific monoclonal antibodies. 35% sites...
Optical networks are the leading platform for transfer of information due to their low loss and ability scale many channels using optical frequency modes. To fully leverage quantum properties light in this platform, it is desired manipulate higher-dimensional superpositions by orchestrating linear, beamsplitter-type interactions between several simultaneously. We propose a method achieving simultaneous, all-to-all coupling <a:math...
It has generally been assumed, based on previous epidemiologic and utilization studies as well the increasing elderly population, that there would be an need for periodontal treatment. Analysis of a more recent household survey conducted in 1981 indicates treatment periodontitis is less than estimates. These data have translated into needs through series conversion rules derived from current patterns treatment, applied to 1985 U.S. population. The total services needed scaling, surgery,...
The 4.3m Discovery Channel Telescope delivers an f/6.1 unvignetted 0.5° field to its RC focal plane. In order support guiding, wavefront sensing, and instrument installations, a Cassegrain assembly has been developed which includes facility guider sensor package (GWAVES) multiple interfaces for instrumentation. A 2-element, all-spherical, fused-silica corrector compensates curvature astigmatism over the FOV, while reducing ghost pupil reflections minimal levels. Dual roving GWAVES camera...
We report soliton-effect pulse compression of low energy ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mo>∼</mml:mo> <mml:mn>25</mml:mn> <mml:mspace width="thickmathspace"/> <mml:mrow class="MJX-TeXAtom-ORD"> <mml:mi mathvariant="normal">p</mml:mi> mathvariant="normal">J</mml:mi> </mml:mrow> </mml:math> ), picosecond pulses on a photonic chip. An ultra-low-loss, dispersion-engineered 40-cm-long waveguide is used to compress 1.2-ps by factor 18, which...
Using x-ray spectroscopy, we demonstrate the existence of 0.3–6 keV electrons in a low-pressure, low-power, magnetized plasma source, heated by an external radio-frequency antenna located at one end axisymmetric tandem mirror. X-ray measurements on low-bulk-temperature, Te,b ∼ 4 eV, hydrogen, neon, argon, and gas-mixture plasmas show spectra with high-energy tails having near-Maxwellian form Te,f up to 650 eV. The fast producing these x-rays have densities range 107–109 cm−3, 0.01%–1% bulk...
As a result of European Union funded project (DentEd), programme visits to dental schools throughout Europe has been underway since 1998. This report describes the philosophy behind DentEd, gives brief description features visitation, and covers orthodontic paediatric dentistry teaching as reported in 26 different 16 countries. It is based on submitted DentEd from small working group that looked at various aspects educational provision within two disciplines across Europe. The value this...
We propose multipartite Bragg-scattering to perform all-to-all transformation among N frequency modes, realizing a bosonic N-level system. demonstrate the = 3 case illustrating pathway towards scalability for frequency-domain optical quantum information systems.
Optical networks are the leading platform for transfer of information due to their low loss and ability scale many channels using optical frequency modes. To fully leverage quantum properties light in this platform, it is desired manipulate higher-dimensional superpositions by orchestrating linear, beamsplitter-type interactions between several simultaneously. We propose a method achieving simultaneous, all-to-all coupling N modes via N-way Bragg-scattering four-wave mixing. By exploiting...
We demonstrate the generation of a 4-photon, dual-rail cluster state with lower-bound fidelity 0.81 consisting sequences dual-color photon pairs. Our approach is extendable to general NxM states.
Using Bragg-scattering four-wave mixing, we prepare frequency-bin qubits and measure a purity of 0.92 through lossy channel, suggesting viability for quantum networks using existing telecommunications infrastructure. Such qubit obviates the polarization-compensation requirement polarization qubits.
We demonstrate frequency conversion between 1283 nm and 705 using Bragg scattering four-wave mixing in a microresonator, which represents the largest span demonstrated. Our noise measurements suggest it is suitable for quantum applications.
