Histometric evaluation of periodontal surgery I. The modified Widman flap procedure (1980)

The present investigation was performed in the Rhesus monkey to determine the effect of the modified Widman flap procedure on the level of the connective tissue attachment and supporting alveolar bone. Two adult male Rhesus monkeys were used. Eighteen contralateral pairs of periodontal pockets were produced in a standardized manner. Surgical treatment of the pockets was performed around experimental teeth and the contralateral teeth were used as the unoperated controls. Twelve months following treatment the animals were sacrificed and histological sections obtained. Using the cemento-enamel junction (CEJ) as a fixed reference point, linear measurements along the root surface were made to the most apical cells of the junctional epithelium (JE), to the crest of the interproximal alveolar bone (CR), and to the apical extent of angular bony defects (AAD). These measurements from operated and unoperated pockets were then compared. The data revealed that treatment of periodontal pockets using the modified Widman flap procedure produced no gain in connective tissue attachment and no increase in crestal bone height. In angular bony defects a certain degree "bone fill" was noted. This bone repair was never accompanied by new connective tissue attachment.
Viet Nam (2017)

Abstract Viet Nam is a populous Southeast Asian economy with a particular socioeconomic and political history. At the end of the ‘American War’ in 1975 ambitions for the future were high, but despite its many potentials, the economy remained poor. International isolation played its role as did centralist policies; and the five-year plan adopted in 1976 turned out as a complete failure. Economic policies started to be reversed following economic collapse in the mid-1980s, and Viet Nam initiated its home-grown Doi Moi reform process. Accordingly, wide-ranging institutional reforms have been gradually implemented since then, including a greater reliance on market forces in the allocation of resources and the determination of prices. A shift from an economy dominated by the state and cooperative sectors to a situation where the private sector and foreign investment account for a relatively high proportion of GDP can also be noted.
Learning From New York (2012)

Problem, research strategy, and findings: High-rise public housing has been entirely discredited in the United States as a legitimate affordable housing planning strategy because of notorious failures in large cities such as St. Louis and Chicago. Missing from the planning literature is the long-term achievement record of America's largest operator of high-rise public housing, the New York City Housing Authority (NYCHA), which still operates 2,600 buildings primarily in modernist tower-in-the-park superblocks for 403,995 authorized tenants. This article assembles and analyzes historical and contemporary materials to create a portrait of functioning American tower-block public housing. The article discusses both contextual factors (New York's transit network, density, and diversity) and successful long-term management in three areas (daily operations, tenant selection, and lobbying) as key to the NYCHA's preservation of public housing. Takeaway for practice: In operations, NYCHA has maintained large front-line staffing on project grounds that play a critical role both in maintenance and social order. In tenant selection, administrators for decades have maintained greater social mixture and better finances by recruiting and retaining working families and, at the same time, enforcing social control through heavy policing. In politics, NYCHA has successfully lobbied for additional federal and city support. Long-term challenges to project preservation and current challenges in New York are also discussed. The findings raise the possibility of high-density urban towers for low-income residents in strong market cities, provided that sufficient attention is paid to design, tenancy, financing, and social control. Research support: None.

Integration of waveguides and photodetectors in SiGe for 1.3 /spl mu/m operation (1994)

The integration of single-mode rib waveguides and photodetectors in silicon using MBE-grown SiGe-layers is reported. Short photodetectors exhibit dark currents below 200 nA at 7 V reverse bias. For the fiber-waveguide-detector coupling an overall quantum efficiency of 11% has been achieved at 7 V reverse bias for /spl lambda/=1.3 μm. The maximum bandwidth is 2 GHz.
Cognitive, performance, and systems issues for augmented reality applications in manufacturing and maintenance (2002)

This paper presents cognitive studies and analyses relating to how augmented reality (AR) interacts with human abilities in order to benefit manufacturing and maintenance tasks. A specific set of applications is described in detail, as well as a prototype system and the software library that it is built upon. An integrated view of information flow to support AR is also presented, along with a proposal for an AR media language (ARML) that could provide interoperability between various AR implementations.
Bronchoscopic laser surgery (1982)

Endoscopic laser surgery for stenotic lesions of inferior respiratory tract has been performed in two ways. One is the carbon dioxide laser surgery under specially designed rigid bronchoscope and the other is Nd-YAG laser surgery through the flexible fiberscope. As for the easy maneuverbility and visibility of the operation's field, the Nd-YAG laser surgery is definitely superior to CO2 laser surgery. But the extent of the exfoliated necrotic tissue for the irradiated area could be more accurately estimated in CO2 laser than in YAG laser. Endoscopic laser surgery is the choice of treatment for the stenotic lesions of the respiratory tract. But in the case of circular cicatricial stenosis, insertion of a silicone tube using an oral approach following laser vaporization may be useful for the prevention of a recurrent. stenosis. The insertion of silicone tube using an oral approach has the following clinical merits.1) there is no tracheal opening necessary, 2) troublesome suction of secreation is not necessary, and 3) normal speech is possible immediately after surgery.
The 4D trajectory data link (4DTRAD) service - Closing the loop for air traffic control (2009)

One of the key services envisioned in support of the NextGen and SESAR concepts is the 4D Trajectory Data Link (4DTRAD) Service, which is being defined by RTCA SC-214 and EUROCAE WG78. One key principle of these concepts is the use of a closed loop clearance from takeoff to landing. The aim of 4DTRAD is to provide a data communication service for ATC clearances and a trajectory downlink application for trajectory data from the aircraft to the ground system to support enhanced trajectory modeling, coordination and constraint conformance monitoring. This data link service will enable the users to leverage advanced airborne avionics that can accurately and efficiently manage the flight of aircraft in 4 dimensions to meet ATC imposed trajectory constraints. 4DTRAD will allow optimized flight profiles while supporting dynamic demand, capacity balancing and queue management during the execution phase of the flight in the strategic conflict management layer, and for non time critical communication. Benefits include reductions in flight delay, fuel consumption, emissions, environmental noise, pilot and controller workload, and frequency congestion. The 4DTRAD service described in this paper is focused on the mid-term (approximately 2015 - 2020) which is anticipated to be a transition environment where mixed equipage is expected to be predominant. This paper presents technologies that are planned to be used and improved as part of NextGen and SESAR that will improve the predictability of the aircraft trajectories and facilitate use of optimized profile descent procedures in high density terminal areas. This paper also raises concerns about challenges in implementing this integrated solution.
Low-Power High-Drive CMOS Operational Amplifiers (1983)

Low-power CMOS op amps with high-drive capability and good settling characteristics are described. One circuit, occupying 150 mils/sup 2/ of active area and consuming 1 mW of power drives a capacitive load of up to 150 pF with greater than +-2.5 V/µs slew rates and less than 3.5 µs settling time to 0.1 percent. A somewhat larger circuit drives low-resistance (e.g., 600 Omega) and high-capacitance (1000 pF) loads with better slew rates and settling time. These circuits are suitable for applications in such systems as charge-redistribution codecs and switched-capacitor filters.
High Resolution Powder Diffraction and Structure Determination (1999)

It is clear that high-resolution synchrotrons X-ray powder diffraction is a very powerful and convenient tool for material characterization and structure determination. Most investigations to date have been carried out under ambient conditions and have focused on structure solution and refinement. The application of high-resolution techniques to increasingly complex structures will certainly represent an important part of future studies, and it has been seen how ab initio solution of structures with perhaps 100 atoms in the asymmetric unit is within the realms of possibility. However, the ease with which temperature-dependence measurements can be made combined with improvements in the technology of position-sensitive detectors will undoubtedly stimulate precise in situ structural studies of phase transitions and related phenomena. One challenge in this area will be to develop high-resolution techniques for ultra-high pressure investigations in diamond anvil cells. This will require highly focused beams and very precise collimation in front of the cell down to dimensions of 50 {micro}m or less. Anomalous scattering offers many interesting possibilities as well. As a means of enhancing scattering contrast it has applications not only to the determination of cation distribution in mixed systems such as the superconducting oxides discussed in Section 9.5.3, but also to the location of specific cations in partially occupied sites, such as the extra-framework positions in zeolites, for example. Another possible application is to provide phasing information for ab initio structure solution. Finally, the precise determination of f as a function of energy through an absorption edge can provide useful information about cation oxidation states, particularly in conjunction with XANES data. In contrast to many experiments at a synchrotron facility, powder diffraction is a relatively simple and user-friendly technique, and most of the procedures and software for data analysis are familiar to laboratory diffractionists. This is reflected in the fact that there are already dedicated instruments for powder diffraction at a number of synchrotrons sources, including the NSLS, the Synchrotrons Radiation Source, Daresbury, the Photon Factory, Tsukuba and HASYLAB. In addition, most general purpose beamlines can be adapted for powder diffraction experiments fairly easily. Dedicated beamlines are also planned or under consideration at the next generation of synchrotrons sources, the European Synchrotron Radiation Facility, Grenoble, the Advanced Photon Source, Argonne, and the SPring-8 machine at Harima. These will be high brilliance sources with a much harder radiation spectrum that will offer many new possibilities for powder diffraction experiments, especially at energies above 10 keV.

Continuous microfluidic airborne bacteria separation using dielectrophoresis (2009)

Airborne microbes such as bacteria are a threat to public health. To prevent and control such dangerous biological particles, robust and real-time detection systems are necessary. For direct and real-time detection of airborne microbes, samples must be collected and typically re-suspended in liquid prior to detection; however, environmental particles such as dust are also trapped in such samples. Therefore, the isolation of target bacteria or selective collection of microbes from unwanted non-biological particles prior to detection is of great importance. Dielectrophoresis (DEP), the translational motion of particles in non-uniform electric fields, is an emerging technique that can rapidly separate biological particles in microfluidics. In this paper, we propose a new method for the separation of airborne microbes using DEP with a simple and novel curved electrode design for separating bacteria in a solution containing beads or dust which is taken from an airborne environmental sample. As there has been little research on analyzing environmental samples using microfluidics and DEP, this work describes a novel strategy for a rapid and direct bioaerosol monitoring system.
The design and evaluation of a generic method for generating mosaicked multispectral filter arrays (2006)

The technology of color filter arrays (CFA) has been widely used in the digital camera industry since it provides several advantages like low cost, exact registration, and strong robustness. The same motivations also drive the design of multispectral filter arrays (MSFA), in which more than three spectral bands are used. Although considerable research has been reported to optimally reconstruct the full-color image using various demosaicking algorithms, studies on the intrinsic properties of these filter arrays as well as the underlying design principles have been very limited. Given a set of representative spectral bands, the design of an MSFA involves two issues: the selection of tessellation mechanisms and the arrangement/layout of different spectral bands. We develop a generic MSFA generation method starting from a checkerboard pattern. We show, through case studies, that most of the CFAs currently used by the industry can be derived as special cases of MSFAs generated using the generic algorithm. The performance of different MSFAs are evaluated based on their intrinsic properties, namely, the spatial uniformity and the spectral consistency. We design two metrics, static coefficient and consistency coefficient, to measure these two parameters, respectively. The experimental results demonstrate that the generic algorithm can generate optimal or near-optimal MSFAs in both the rectangular and the hexagonal domains.
Yield Modeling of Arbitrary Defect Outline (2006)

In integrated circuits(IC), the defects associated with photolithography are assumed to be the shape of circular discs in order to perform the estimation of yield and fault analysis. However, real defects exhibit a great variety of shapes. Based on the real outlines of the defects and the mathematical morphology, a novel yield model is presented and the critical area model is provided correspondingly. Since they avoid changing the defects into the shape of circular discs, the models predict the yield caused by the defects more accurately than the circular discs model does. Experimental results showing the model's performance are presented. It is significant that the yield is accurately estimated using the proposed model

Color correction for mobile panorama imaging (2009)

This paper presents a simple and efficient color and luminance compensation approach for image sequences for constructing panoramic images on mobile devices. In this approach, constant compensation coefficients for adjacent images are computed from the corresponding pixels in the overlapping areas of the adjacent images in the linearized RGB color space. A global adjustment for all compensation coefficients is performed so that the correction for each image is as small as possible. This can smooth color transition between adjacent images in the image sequence globally and reduce cumulative errors in the color correction process. The compensation coefficients, together with the global adjustment factor, are applied to correct color and luminance of source images in the image sequence before they are stitched into a panoramic image.
2.7 A wideband 28GHz power amplifier supporting 8×100MHz carrier aggregation for 5G in 40nm CMOS (2017)

To meet rising demand, broadband-cellular-data providers are racing to deploy fifth generation (5G) mm-wave technology, e.g., rollout of some 28GHz-band services is intended in 2017 in the USA with ~5/1Gb/s downlink/uplink targets. Even with 64-QAM signaling, this translates to an RF bandwidth (RFBW) as large as ~800MHz. With ~100m cells and a dense network of 5G access points (APs), potential manufacturing volumes make low-cost CMOS technology attractive for both user equipment (UE) and AP devices. However, the poor P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">out</sub> and linearity of CMOS power amplifiers (PAs) are a bottleneck, as ~10dB back-off is typical for meeting error-vector-magnitude (EVM) specifications. This limits communication range and PA power added efficiency (PAE), with wider RFBWs accentuating these issues further. On the other hand, sufficient element counts in the envisaged 5G phased-array modules can overcome path loss despite low P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">out</sub> per PA, e.g., by combining RFICs in an AP. CMOS PAs with wideband linearity/PAE can therefore enable economical UE/AP devices to deliver 5G data-rates.
Binding properties of monoclonal anti-IgG antibodies: analysis of binding curves in monoclonal antibody systems. (1984)

The binding properties of an immune complex-forming system comprising human IgG and mouse monoclonal antibodies against human IgG have been studied. A refined binding assay has been applied directly on ascitic fluid containing monoclonal antibody. Complete sets of binding data of a series of different monoclonal antibodies were collected and analysed by various graphical and statistical methods. Special attention was given to methods which allow determination of specific monoclonal antibody concentration as well as antibody affinity. It was found that the formation of genuine antigen: antibody complexes per se gives rise to deviations from expected linearity in commonly used binding equations. Good correlation was found between the antibody concentrations obtained by various graphical approaches, whereas the size of the association constant seemed to depend on the method in use. The binding pattern was found to be dependent on the concentration of antibody. Most reliable parameters were obtained if the product of the antibody concentration and the association constant was below 10.
Inverse halftoning using binary permutation filters (1995)

The problem of reconstructing a continuous-tone image given its ordered dithered halftone or its error-diffused halftone image is considered. We develop a modular class of nonlinear filters that can reconstruct the continuous-tone information preserving image details and edges that provide important visual cues. The proposed nonlinear reconstruction algorithms, denoted as binary permutation filters, are based on the space and rank orderings of the halftone samples provided by the multiset permutation of the "on" pixels in a halftone observation window. For a given window size, we obtain a wide range of filters by varying the amount of space-rank ordering information utilized in the estimate. For image reconstructions from ordered dithered halftones, we develop periodically space-varying filters that can account for the periodical nature of the underlying screening process. A class of suboptimal but simpler space-invariant reconstruction filters are also proposed and tested. Constrained LMS type algorithms are employed for the design of reconstruction filters that minimize the reconstruction mean squared error. We present simulations showing that binary permutation filters are modular, robust to image source characteristics, and that they produce high visual quality image reconstruction.
High‐Performance Inkjet Printed Carbon Nanotube Thin Film Transistors with High‐k HfO<sub>2</sub> Dielectric on Plastic Substrate (2012)

Inkjet printing is used to fabricate CN-TFT devices on PET substrate with 70 nm HfO2 gate dielectric. By varying the amount of printing, effective mobility can be raised to 43 cm2 V−1 s−1 with on/off ratio ≥ 104 for devices with channel length 160 μm. This demonstrates that inkjet printing is promising for fabrication of high-performance devices in flexible electronics.
High-Pressure Testing of Composite Solid Propellant Mixtures: Burner Facility Characterization (2005)

Much Research on composite solid propellants has been performed over the past few decades and much progress has been made, yet many of the fundamental processes are still unknown, and the development of new propellants remains highly empirical. Ways to enhance the performance of solid propellants for rocket and other applications continue to be explored experimentally, including the effects of various additives and the impact of fuel and oxidizer particle sizes on burning behavior. One established method to measure the burn rate of composite propellant mixtures in a controlled laboratory setting is to use a constant-volume bomb, or strand burner. To provide high-pressure burn rate data at pressures up to 360 atm, the authors have installed and characterized a new strand burner facility at the University of Central Florida. Details on the new facility and the measurement procedures are summarized. Repeatability between different batches of the same mixture has been demonstrated to be very good, and two common HTPB/Ammonium Perchlorate (AP) propellant mixtures containing 7/3 and 5/5 bimodal AP distributions were tested in the burner. The resulting burn rates are compared to data from the literature with good agreement in burn rate exponent and the impact of changing from a 7/3 to a 5/5 AP split.
