A new classification scheme for periodontal and peri‐implant diseases and conditions – Introduction and key changes from the 1999 classification (2018)

A classification scheme for periodontal and peri-implant diseases and conditions is necessary for clinicians to properly diagnose and treat patients as well as for scientists to investigate etiology, pathogenesis, natural history, and treatment of the diseases and conditions. This paper summarizes the proceedings of the World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions. The workshop was co-sponsored by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP) and included expert participants from all over the world. Planning for the conference, which was held in Chicago on November 9 to 11, 2017, began in early 2015. An organizing committee from the AAP and EFP commissioned 19 review papers and four consensus reports covering relevant areas in periodontology and implant dentistry. The authors were charged with updating the 1999 classification of periodontal diseases and conditions and developing a similar scheme for peri-implant diseases and conditions. Reviewers and workgroups were also asked to establish pertinent case definitions and to provide diagnostic criteria to aid clinicians in the use of the new classification. All findings and recommendations of the workshop were agreed to by consensus. This introductory paper presents an overview for the new classification of periodontal and peri-implant diseases and conditions, along with a condensed scheme for each of four workgroup sections, but readers are directed to the pertinent consensus reports and review papers for a thorough discussion of the rationale, criteria, and interpretation of the proposed classification. Changes to the 1999 classification are highlighted and discussed. Although the intent of the workshop was to base classification on the strongest available scientific evidence, lower level evidence and expert opinion were inevitably used whenever sufficient research data were unavailable. The scope of this workshop was to align and update the classification scheme to the current understanding of periodontal and peri-implant diseases and conditions. This introductory overview presents the schematic tables for the new classification of periodontal and peri-implant diseases and conditions and briefly highlights changes made to the 1999 classification. It cannot present the wealth of information included in the reviews, case definition papers, and consensus reports that has guided the development of the new classification, and reference to the consensus and case definition papers is necessary to provide a thorough understanding of its use for either case management or scientific investigation. Therefore, it is strongly recommended that the reader use this overview as an introduction to these subjects. Accessing this publication online will allow the reader to use the links in this overview and the tables to view the source papers (Table ).
Improved Method for Determination of Triglycerides in Serum (1973)

Abstract We describe a new method for determination of serum triglycerides that is based on the original method of Fletcher [Clin. Chim. Acta22, 393 (1968)]. We have modified Fletcher’s reagents so that it is possible to saponify serum triglycerides in 5 min at room temperature (about 24 °C) instead of 60-70 °C for 15 min and to produce the final color in 15 min at 60-70 °C instead of 30 min at 50 ° C. The new reagents are stable for at least two months. The correlation coefficient obtained for the two methods (n = 107 sera) was 0.98. When the t test and F test were applied to these data, no significant difference in accuracy and precision was found at the 95% confidence level. The coefficient of variation (day-to-day) for the new method is 7.0%.
3.2 multi-standard 185fs<inf>rms</inf> 0.3-to-28Gb/s 40dB backplane signal conditioner with adaptive pattern-match 36-Tap DFE and data-rate-adjustment PLL in 28nm CMOS (2015)

As processing and network speeds are accelerated to support data-rich services, the bandwidth of backplane interconnects needs to be increased while maintaining the channel length and multi-rate links. However, channel losses and impedance discontinuities increase at high data-rates, making it difficult to compensate the channel. In this work, we target serial links from auto-negotiation in 100G-KR4 of 0.3Gb/s to 32GFC of 28.05Gb/s in 40dB backplane architecture. To achieve this challenge, there are two key techniques. First, we introduce a 36-tap decision-feedback equalizer (DFE) to cancel reflections due to connectors because these reflections close the eye. To operate the 36-tap DFE, we need to fix a CDR lock-point and calculate 36-tap coefficients accurately. Thus, we develop a pattern-captured CDR with a 4b pattern filter to fix the lock-point, and a 3b pattern-matched adaptive equalizer (AEQ) to optimize 36 tap coefficients. These techniques enable our chip to compensate 40dB channel loss. Second, we target 100G-KR4/40G-KR4/10G-KR/25G-KR and 32GFC/16GFC/8GFC/4GFC. To operate across a wide range of data-rates, from 0.3 to 28.05Gb/s, with low jitter, we develop a PLL architecture with two LC-VCOs and one ring VCO with a data-rate-adjustment technique by controlling an LDO. Our test chip is fabricated in 28nm CMOS. Our signal conditioner is the demonstration to achieve the BER <;10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</sup> PRBS31 at 100G-KR4 in a 40dB chip-to-chip backplane with two connectors by using the 36-tap DFE to cancel the reflection and to operate across a wide range of data-rates from 0.3 to 28.05Gb/s.
An electrochemical array sensor with CMOS signal processing circuits integrated on a single chip (2010)

We have designed and fabricated a 2×4 electrochemical image sensor with CMOS signal processing circuits integrated on a single chip. Using a well-studied ferricyanide solution, a clear cyclic voltammetry curve was obtained from each working electrode of the array sensor. The external components used include a data generator and a data recorder. This sensor chip is an early prototype of a fully integrated system of a fast-scan electrochemical image sensor that uses microelectrodes.
Alignment-stabilized grating-tuned external-cavity semiconductor laser (1990)

We have demonstrated an alignment-stabilized cavity configuration for a grating-tuned external-cavity semiconductor laser using a cylinder lens to form a line focus on the surface of the grating. The grating in the stabilized cavity has a 350-fold greater angular misalignment tolerance than in a conventional collimated-beam cavity, while the same spectral resolution is maintained.

Demyelination induced by serum form patients with Guillain‐Barré syndrome (1984)

Sera from 16 patients with acute Guillain-Barré syndrome (GBS) and 14 healthy control subjects were injected into rat sciatic nerve and assessed for demyelinating activity by electrophysiological and histological techniques. Only fresh GBS serum, and not GBS serum stored at -20 degrees C or -70 degrees C, blocked conduction to a significantly greater extent than did fresh control serum. Conduction block developed gradually, starting within 24 hours of injection and reaching a maximum between days 3 and 6. Recovery of conduction commenced thereafter, and conduction returned to normal by day 33. Quantitative histological studies on day 6 showed that fresh GBS serum produced significantly more widespread demyelination than did stored GBS serum (p less than 0.01). Stored GBS serum showed residual demyelinating activity when compared with fresh control serum (p less than 0.01). Fresh serum obtained from 4 patients after recovery from GBS did not produce conduction block, despite it having done so during the acute phase of the disease.

Performance and reliability of mems gyroscopes at high temperatures (2010)

This paper reports the variation in the noise and signal output of a 3-axis MEMS gyroscope that results from physical degradation of the MEMS gyroscope sensor or its packaging caused by long time exposure to wide temperature cycling to high temperatures. Three different 3-axis MEMS gyroscopes were used for this analysis. This study was accomplished by measuring the signal and noise variation at stationary and rotary conditions. Both stationary and rotary tests were conducted at room temperature, and angular velocity was measured in °/s. For the rotary test measurement, the 3-axis MEMS gyroscope was placed on a precise rotary table and rotated at 60°/s (10 rpm), 120°/s (20 rpm) and 240°/s (40 rpm) for five minutes each. These MEMS gyroscopes were then subjected to thermal cycling from -25°C to 125°C for 100 hours (100 cycles).This process was repeated five times for a total of 500 hours of thermal cycling. The same stationary and rotary test measurements were conducted after every 100 hours of thermal cycling exposure to 500 hours. A permanent change in the signal was measured, which is discussed in this paper.
Metabolic Correction of Cerebral Radiation Syndrome (1999)

DNA strand breaks that occur after irradiation activate the repair enzyme adenosine diphosphoribosyl transferase, which consumes NAD as a substrate and causes depletion first of neuronal NAD and then of the ATP pool. This is considered to be the crucial link in the mechanism underlying the cerebral radiation syndrome (CRS). In this study, two ways to correct the CRS metabolically were examined: (a) prevention of depletion of NAD after irradiation by administration of the enzyme inhibitor nicotinamide and (b) shunting the NAD-dependent oxidative phosphorylation pathway of ATP resynthesis by administration of a substrate of NAD-independent oxidation, succinate. Cerebral lesions induced by radiation were modeled by irradiation of rats or rat brain homogenates with 150 Gy of X rays. The manifestations of CRS in rats (excitement, convulsions, etc.) closely resembled those seen after acute hypoxia. In brain homogenates, pyruvate tetrazolium-reductase activity decreased after irradiation and could be corrected by addition of NAD after irradiation. Succinate tetrazolium-reductase activity was not affected by irradiation. Oxygen consumption by brain homogenates after irradiation in vitro and in situ decreased, as did oxygen consumption by rats in vivo after cranio-caudal irradiation. Administration of nicotinamide or succinate prevented both the postirradiation decrease in respiration (in both rats in vivo and brain homogenates in vitro) and the development of cerebral radiation syndrome. These results help to clarify the mechanisms underlying CRS and its metabolic correction.
Natural feature tracking on a mobile handheld Tablet (2013)

This paper presents a natural feature tracking system for object recognition in real-life environments. The system is based on a local keypoint descriptor method optimized and adapted to extract salient regions within the image. Each object in the gallery is characterized by keypoints and corresponding local descriptors. The method first identifies gallery object features in new images using nearest neighbor classification. It then estimates camera pose and augments the image with registered synthetic graphics. We describe the optimizations necessary to enable real-time performance on a mobile tablet. An experimental evaluation of the system in real environments demonstrates that the method is accurate and robust.
A System for Controlling the Night Temperature of Fruit Trees1 (1968)

Abstract The influence of temperature on the growth and development of deciduous tree fruits has been inadequately investigated. In most cases only general field observations have been reported. The temperature conditions prior to and during such general observations are variable and cannnot be repeated precisely. To control temperature, limb sleeves and small chambers have been used to cover portions of limbs (2,3). Information from such devices is of limited value since they do not preclude the influence of the rest of the tree.
Synthesis and Biological Activity of Arthrographol and Related Compounds (1996)

i)-A~thrographol ( l a ) and related compounds were synthesized and their inhibitory activities against Slipoxygenase were investigated.The l'(Z)-isomer (1 b) of arthrographol was found to be three times active than arthrographol itself. Aahrographol (la) was isolated as an antibiotic and a chitin synthase inhibitor from the metabolites of ~r t h r o g r ~h i s ~i n i c o ~and Aspergillus o r y ~a e .~ Recently, arthrographol was found to be a potent inhibitor3 of 5-lipoxygenase which is the first enzyme in the course of the biological transformation of arachidonic acid to leukotrjenes causing inflammation and allergy.We describe here syntheses of(*)-atthrographo14 (la) and its isomers ( l b and 2) and their inhibitory activities against Slipoxygenase.
Longitudinal dynamics in an ffag accelerator under conditions of rapid acceleration and fixed, high RF (2004)

A signature of fixed-field acceleration is that the orbit of the beam centroid unavoidably changes with energy. The corresponding change in pathlength results in phase slip relative to the fixed-frequency accelerating waveform. Nevertheless, depending on the location of the fixed-points of the motion, synchronous or asynchronous cross-crest acceleration is possible for a limited number of turns. The possibility of asynchronous rf can be understood simply by realizing that for acceleration in a single pass, the initial cavity phases can be set to exactly compensate for the phase slip. The present work explores the influence of the path-length fixed points and of rf manipulations on the longitudinal dynamics in FFAGs.

Comparison between optical fiber birefringence induced by stress anisotropy and geometric deformation (2000)

A variational formulation-based vector perturbation model is used to compare the contribution of stress anisotropy and geometric deformation toward optical fiber birefringence. We show that relative impact of stress on birefringence and differential group delay depends significantly on the exact fiber index profile.
On Cyber Warfare Command and Control Systems (2004)

As Defense agencies and services expand their reliance on computer networks, risk to information availability and integrity increases. It is no longer adequate to rely solely on the now traditional defense-in-depth strategy. We must recognize that we are engaged in a form of warfare, cyber warfare, and deploy our resources using the strategy and tactics of warfare. Most Defense organizations have not yet developed strategies or tactics for cyber warfare. This causes security devices to be used ineffectively and responses to be untimely. Cyber warfare then becomes a one-sided battle where the attacker makes all the strikes and the target of the attack responds so slowly that the attacker usually gets away without being identified. Employing cyber warfare strategy and tactics requires a cyber warfare command and control system. Responses to cyber attacks do not require offensive measures outside our own network boundaries to be effective, but they do require timely responses. Timely offensive action taken within our own network boundaries can lead to an identification of the attacker. During the past two years we have developed a prototype cyber warfare command and control system to demonstrate that defense-in-depth can be taken to a new level that is active and anticipatory rather than passive and reactive. 1.
The derivation of clinical‐grade human embryonic stem cell lines (2006)

The pluripotent nature of human embryonic stem cells (hESC) has attracted great interest in using them as a source of cells or tissue in cell therapy. However, in order to be used in regenerative medicine, the pluripotent hESC lines should be established and propagated according to good manufacturing practice quality requirements. The cultures should be animal substance free in order to exclude the risk of infections and immunogenity. They should also be genetically and epigenetically normal. The detailed molecular mechanisms of their pluripotency are still not defined. Using human feeder cells, a medium containing only human proteins, the mechanical isolation of the inner cell mass and mechanical passaging of hESC, is a safe option until a functional defined medium containing physiological concentrations of regulatory factors is available.
A Practical Multiple Reflection Technique for Improving the Quantum Efficiency of Photomultiplier Tubes (1968)

A technique is described by which multiple reflection techniques can be used to increase the quantum efficiency of some end-on photomultiplier tubes in the red and near ir. The method can be used in practice for astronomical and other applications where field lens imaging on the cathode is required and where small cathodes are desirable. Tests of a group of unselected production model S-20 and S-1 photomultiplier tubes show quantum efficiency gains as high as factors of 3.8 and 1.8, respectively, at practical operating wavelengths.
