Review article: the efficacy of infliximab in Crohn’s disease — healing of fistulae (1999)

In the management of fistulae, the current therapeutic approach is the use of a combination of antibiotics and/or a combination of immunomodulatory agents. However, clinicians treating patients with fistulae, particularly those with fistulizing Crohn's disease, have little data from controlled clinical trials of these pharmacologic agents or regimens to substantiate their use in treating this complication. Therapy with the anti-tumour necrosis factor-alpha antibody, infliximab, has shown promise in treating patients with Crohn's disease and those with the disease complicated by fistulae. A recent clinical trial was designed specifically to evaluate infliximab in the treatment of fistulizing Crohn's disease. Study results demonstrated infliximab to be the first therapeutic agent to show statistical efficacy in fistulae closure in a placebo-controlled trial. Therapy with the chimeric monoclonal antibody was characterized by a rapid onset of closure and a lasting benefit of action. Two patient cases from the clinical trial are presented to exemplify the dramatic effectiveness of this novel therapeutic approach in modulating the immune response of patients with this debilitating complication of Crohn's disease.
Reverse link demodulator ASIC for CDMA cellular system (1996)

In this paper, we describe the design and implementation of a code division multiple access (CDMA) base station demodulator (CBD) ASIC for the use in the IS95-based CDMA mobile communication system. We propose a novel design method for the noncoherent OQPSK PN correlator, fast Hadamard transformer (FHT), lock detector, and time tracking loop, which are the main functional blocks of the demodulator. We also present the implementation environment for the design and verification of the demodulator ASIC. The chip has been designed using a cell-based design methodology and fabricated by double-metal 0.8-/spl mu/m CMOS technology. The die of the chip measures 8.1/spl times/8.3 mm and it contains approximately 75000 logic gates and 3000 bits of static RAM.

This double-tracer autoradiography with 3H and 14C which has high sensitivity, a high spatial resolution of 50 microns and superior linearity with a wide dynamic range of 10(4) to 10(5) allows accurate quantification of the tissue radioactivity of the two radiopharmaceuticals.
Retinal Damage in Chloroquine Maculopathy, Revealed by High Resolution Imaging: A Case Report Utilizing Adaptive Optics Scanning Laser Ophthalmoscopy (2014)

A 53-year-old Asian woman was treated with hydroxychloroquine and chloroquine for lupus erythematosus. Within a few years, she noticed circle-shaped shadows in her central vision. Upon examination, the patient's visual acuity was 20 / 25 in both eyes. Humphrey visual field (HVF) testing revealed a central visual defect, and fundoscopy showed a ring-shaped area of parafoveal retinal pigment epithelium depigmentation. Fundus autofluorescence imaging showed a hypofluorescent lesion consistent with bull's eye retinopathy. Adaptive optics scanning laser ophthalmoscope (AO-SLO) revealed patch cone mosaic lesions, in which cones were missing or lost. In addition, the remaining cones consisted of asymmetrical shapes and sizes that varied in brightness. Unlike previous studies employing deformable mirrors for wavefront aberration correction, our AO-SLO approach utilized dual liquid crystal on silicon spatial light modulators. Thus, by using AO-SLO, we were able to create a photographic montage consisting of high quality images. Disrupted cone AO-SLO images were matched with visual field test results and functional deficits were associated with a precise location on the montage, which allowed correlation of histological findings with functional changes determined by HVF. We also investigated whether adaptive optics imaging was more sensitive to anatomical changes compared with spectral-domain optical coherence tomography.

FIR compensation filter for the zero order hold D/A converter using the frequency sampling method (2002)

This paper presents a digital FIR filter for compensating the frequency response caused by the D/A's zero order hold (ZOH) characteristics at no cost of additional hardware. The FIR compensation filter is designed using the frequency sampling method. This FIR filtering is shown to adequately correct the ZOH's frequency response by the simulation results and by the DSP hardware implementation. The compensation filtering is shown to be an effective method of correcting the limitations introduced by the DSP hardware without increasing the sampling rate and without introducing the phase distortion.
Assessing the Potential of Low-Cost 3D Cameras for the Rapid Measurement of Plant Woody Structure (2013)

Detailed 3D plant architectural data have numerous applications in plant science, but many existing approaches for 3D data collection are time-consuming and/or require costly equipment. Recently, there has been rapid growth in the availability of low-cost, 3D cameras and related open source software applications. 3D cameras may provide measurements of key components of plant architecture such as stem diameters and lengths, however, few tests of 3D cameras for the measurement of plant architecture have been conducted. Here, we measured Salix branch segments ranging from 2-13 mm in diameter with an Asus Xtion camera to quantify the limits and accuracy of branch diameter measurement with a 3D camera. By scanning at a variety of distances we also quantified the effect of scanning distance. In addition, we also test the sensitivity of the program KinFu for continuous 3D object scanning and modeling as well as other similar software to accurately record stem diameters and capture plant form (<3 m in height). Given its ability to accurately capture the diameter of branches >6 mm, Asus Xtion may provide a novel method for the collection of 3D data on the branching architecture of woody plants. Improvements in camera measurement accuracy and available software are likely to further improve the utility of 3D cameras for plant sciences in the future.
A contextual algorithm for AVHRR fire detection (1996)

Abstract A contextual algorithm for fire detection with NOAA-AVHRR-LAC data was developed. Unlike ‘traditional’ fire detection algorithms (e.g., multichannel thresholds), the decision to record a fire is made by comparing a fire pixel with the pixels in its immediate neighbourhood. The algorithm is self-adaptive and therefore very consistent over large areas as well as through seasons. The algorithm appears to operate successfully in most areas of the world. This Letter presents the contextual approach and describes the algorithm.
Extremely small polarization independent phased-array demultiplexers on InP (1996)

Compact, polarization insensitive phased-array wavelength demultiplexers are demonstrated with a deep ridge waveguide. Good agreement with the modeling is found for the birefringence and the refractive index. Zero birefringence is effectively obtained around 1.53 μm. The guiding structure allows curvatures of 100 μm; thus, the grating size of the 4- and 16-channel demultiplexers is reduced to 0.33×0.30 and 1.1×1.1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , with crosstalk below -16 and -14 dB respectively. These are the smallest demultiplexers reported to date.

Expression of α and β integrins during terminal differentiation of cardiomyocytes (2000)

These results suggest that progression through the cardiomyocyte cell cycle may be dependent upon cell attachment via integrin beta1 and correlate with changes that occur in beta1 spliced variants and their respective alpha isoforms.
Temperature Measurements Using a Microoptical Sensor Based on Whispering Gallery Modes (2006)

Temperature measurements were made using a novel microoptical sensor based on dielectric microspheres that are excited by coupling light from optical fibers. The technique exploits the morphology-dependent shifts in resonant frequencies that are commonly referred to as the whispering gallery modes. A change in the temperature of the microsphere leads to a change in both the size and the index of refraction of the sphere which results in a shift of the resonant frequency. By monitoring this shift, the temperature of the environment surrounding the sphere can be determined. The whispering gallery mode shifts are observed by scanning a tunable diode laser that is coupled into the optical fiber on one end and monitoring the transmission spectrum by a photodiode on the other. When the microsphere is in contact with a bare section of the fiber, the optical modes are observed as dips in the intensity of the light transmitted through the fiber. Temperature measurements were made in both air and water using this novel technique. Measurements by the microoptical sensor were compared to those by thermocouples with good agreement between the two sets of results.
Pressureless sintering of h-BN for continuous temperature measurement of melts. (1989)

Pressureless sintered hexagonal boron nitride (h-BN) were fabricated using turbostratic BN and amorphous B as starting powders. Further, the effects of additives on bending strength and corrosion resistance of the sintered BN were studied.Bulk density and bending strength of the sintered BN with additives were significantly increased compared to the case of using pure h-BN as a starting powder. Especially in the sintered BN with 5 wt%SiC, high bending strength, -9kg/mm2, were constantly obtained in the range room temperature to 1200C°C. On the other hand, the sintered BN with 30 wt%AlN had revealed superior corrosion resistance. These materials could be applicable to the protective tube for the continuous temperature measurement of molten steel in the range 1500 to 1560C°C.
Study of tungsten oxidation in O2∕H2∕N2 downstream plasma (2008)

The surface oxidation of tungsten is a serious issue in plasma processing of advanced integrated-circuit devices where tungsten is being used as a gate electrode. In this article, we study tungsten oxidation in O2∕H2∕N2 downstream plasma at a temperature ⩽300°C. The results show that oxidation occurs rapidly in O2 downstream plasma to form stable WO3. However, oxidation can be reduced effectively by adding H2 and totally suppressed when H2 concentration in the gas feed reaches a certain low level at which the plasma is still oxygen dominant. Tungsten oxidation increases significantly with sample temperature and exposure time in O2 downstream plasma. However, H2 addition reduces both temperature and time dependences due to the coexistence and competition of oxidation and reduction processes. When N2 is also added, the efficiency of H2 in O2 downstream plasma in controlling tungsten oxidation is lowered. The findings may provide effective approaches to various applications of selective oxidation over tungsten, such as photoresist stripping and polysilicon oxidation on tungsten gate structures.

Photocrosslinkable chitosan based hydrogels for neural tissue engineering (2011)

Hydrogel based scaffolds for neural tissue engineering can provide appropriate physico-chemical and mechanical properties to support neurite extension and facilitate transplantation of cells by acting as 'cell delivery vehicles'. Specifically, <i>in situ</i> gelling systems such as photocrosslinkable hydrogels can potentially conformally fill irregular neural tissue defects and serve as stem cell delivery systems. Here, we report the development of a novel chitosan based photocrosslinkable hydrogel system with tunable mechanical properties and degradation rates. A two-step synthesis of amino-ethyl methacrylate derivitized, degradable, photocrosslinkable chitosan hydrogels is described. When human mesenchymal stem cells were cultured in photocrosslinkable chitosan hydrogels, negligible cytotoxicity was observed. Photocrosslinkable chitosan hydrogels facilitated enhanced neurite differentiation from primary cortical neurons and enhanced neurite extension from dorsal root ganglia (DRG) as compared to agarose based hydrogels with similar storage moduli. Neural stem cells (NSCs) cultured within photocrosslinkable chitosan hydrogels facilitated differentiation into tubulin positive neurons and astrocytes. These data demonstrate the potential of photocrosslinked chitosan hydrogels, and contribute to an increasing repertoire of hydrogels designed for neural tissue engineering.
MWIR continuous zoom with large zoom range (2010)

Multiple fields of view are achieved by two methods. The system can have optical groups that flip in and out to change the field of view, and/or optical groups that move axially to change the field of view. For flip in systems, the fields of view are discreet and they may have greatly different fields of view. A zoom system can have a continuous change in the field of view, but is often limited in the field of view range that can be achieved. Corning Incorporated has developed a thermal imaging zoom system with greater than 30X zoom range. With a solid fundamental design and appropriate selection of moving group focal lengths, the zoom system provides continuous changes in the field of view from the narrow field of view to the wide field of view. Corning accomplished this result in a short package with just two moving groups. The system is for the MWIR band.
Automatic modeling of switch-level networks using partial orders (MOS circuits) (1990)

It is shown how the substitution of a partial order facilitates automatic modeling in switch-level simulators that use the traditional total ordering of strengths for resolving conflicts between opposing signals while increasing the accuracy of that model. Minimization techniques are described that reduce the number of required modeling strengths to acceptable levels. As a result, the use of partially ordered strengths does not significantly degrade simulation performance. It is also shown how to rearrange the computations performed during switch-level simulation to yield a nearly twofold increase in speed for good circuit simulation. A switch-level simulator using this algorithm with partially ordered strengths has been successfully used to verify several full-custom industrial designs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Decompression incidence in air- and liquid-breathing hamsters. (1983)

The effects of hyperbaric compression on heart rate, rectal temperature, respiratory rate, bubble formation, and survival were studied in three groups of anesthetized golden hamsters (Mesocricetus auratus). Group I (15 animals) breathed air while exposed to 7 ATA of pressure for 1 h in a hyperbaric chamber; Group II (13 animals), at the same pressure level (7 ATA) and for the same time period (1 h), breathed an oxygenated fluorocarbon liquid (temperature 27 degrees C) that was open to the chamber atmosphere; Group III (10 animals), at the same pressure and time period as the other groups, were sealed in a flexible plastic bag filled with oxygenated fluorocarbon as a breathing mixture. A fourth, Group IV (12 animals), breathed oxygenated fluorocarbon for 1 h at 1 ATA. Survival after rapid decompression in each group varied, 9 animals died in Group I, 12 animals in Group II, whereas none of the animals died in either Groups III or IV. Thirty minutes after decompression postmortem examinations of all the animals demonstrated the presence of large amounts of gas bubbles in the right ventricle and some gas bubbles in the left ventricle of all the hamsters in Groups I and II. No gas bubbles were found in the hearts of the Group III animals. Group III animals, breathing a liquid unsaturated by an inert gas, survived rapid explosive decompression without the signs and symptoms of decompression sickness. Immersion in the liquid fluorocarbon produced a profound decrease in heart rate, rectal temperature, and respiration in Groups II, III, and IV.
Performances of decision feedback equalizers using neural networks under frequency selective fading channels (1992)

Evaluates the performance of decision feedback equalizers (DFE) using multilayer neural networks under frequency selective fading channels. A novel DFE is proposed. The proposed DFE uses a neural network which carries out unsupervised learning selectively in a tracking mode. The neural network used can avoid false learning caused by incorrect teacher signals by setting the appropriate threshold to decide whether the learning should be carried out or not. The fading channel to be considered is frequency selective and its statistical characteristics are Rayleigh. Simulation results show that the performance of the DFE using the conventional neural network is superior to that of the conventional DFE and also show that the performance of the proposed DFE is superior to that of the DFE using the conventional neural network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
