A new sensor system for simultaneously detecting the position and incident angle of a light spot (2003)

The present paper describes a newly devised sensor, which has the ability to detect the two-dimensional position and the one-dimensional angle of a light spot simultaneously. Ordinary laser-based measurement systems utilize CCD or PSD sensors. These conventional sensors can detect only a light spot's position. When the sensor can detect the incident angle of a light spot as well as the position, the sensor has a wide range of applicability. The sensor consists of two linear array-type sensors whose depth positions are slightly different. We have designed and built a prototype sensor system. We experimentally verified the practicable accuracy of the present sensor system. We also applied the present sensor system to two typical laser-based measurement systems: 2-D position measurement, and 3-D shape measurement for specular objects. Experimental results show that the sensor system was applicable to a laser-based measurement system.
Monocyte derived dendritic cells generated by IFN-α acquire mature dendritic and natural killer cell properties as shown by gene expression analysis (2007)

Our results suggest that IFN-DC not only stimulate adaptive but also mediate innate antitumor immune responses. Therefore, IFN-DC should be evaluated in clinical vaccination trials. In particular, this could be relevant for patients with diseases responsive to a treatment with IFN-alpha such as Non-Hodgkin lymphoma or chronic myeloid leukemia.
Potential-Induced Enantioselective Uptake of Amino Acid into Molecularly Imprinted Overoxidized Polypyrrole (2000)

Overoxidized polypyrrole films templated with L-glutamate have been utilized for enantioselective detection of L- and D-glutamic acid. Various important fabrication factors controlling the performance of the overoxidized polypyrrole films have been investigated using fluorescence spectrometry in conjugation with the electrochemical quartz crystal microbalance technique. The measured fluorescence intensity was related to the concentration of glutamate taken up into the films. It was found that L-glutamate was inserted approximately 30 times higher into the film than D-glutamate. Several key parameters such as applied potential and pH of amino acid solution were varied to achieve the optimum sensor response. The sensor templated with L-glutamic acid also exhibited excellent selectivity over several other L- and D-amino acids. Higher enantioselectivity of overoxidized polypyrrole film than that for previously reported imprinted polymers can be attributed to the potential-induced uptake/release of targeted molecules.

Improving Automation in Map Updating Based on National Laser Scanning, Classification Trees, Object-Based Change Detection and 3D Object Reconstruction (2007)

Previously, several countries have performed countrywide laser scanning, but mainly for DTM purposes. This paper discusses the possibility to use countrywide collection of laser data, possibly multi-temporal laser data, for updating Topographic and forest databases, especially concerning the detection of the changed buildings or trees and reconstructing them from laser scanner data. Knowledge obtained in both the EuroSDR comparison of building extraction and EuroSDR/ISPRS test on tree extraction is applied in order to predict the obtainable quality. Some examples to use change detection are given. Rough concepts for implementation of the ALS surveys are depicted. The use of high-density cross-strips could be used for both strip adjustment and quality control. The intensity of the collected laser data is proposed to be calibrated. We also propose to use classification tree techniques together with existing methods in order to automatically classify laser point clouds.
Human tracking in the complicated background by Particle Filter using color-histogram and HOG (2010)

Human tracking based on computer vision, is a challenging and crucial problem in intelligent video surveillance system. As is known to all, human motion is usually non-linear and non-Gaussian, many prevalent frameworks are not appropriate, such as Kalman Filter, etc. Nevertheless, the Particle Filter could still have good performance even when the system is nonlinear and non-Gaussian. This paper is based on Particle Filter, too. In many cases, the Particle Filter always uses single-human-feature (such as color-histogram, edge gradient, Histogram of Oriented Gradients (HOG), etc) to track human objects. But using single-human-feature will lose a lot of information in the process of tracking human objects. In order to avoid this drawback, this paper proposes to fuse the information of color-histogram and HOG to track. This method keeps both color and shape information, consequently, it is more robust and steady. Experiment results demonstrate that this method is effective to improve the performance of tracking.
Are maintenance expert systems practical now? (1985)

This paper examines the question of whether Artificial Intelligence expert system technology can be effectively applied to real world maintenance problems. Expert maintenance systems Installed to date are reviewed and the ACE (Automated Cable Expertise) knowledge-based expert system presently marketed by AT&T is described in detail. ACE provides timely trouble-shooting reports and management analyses (or telephone cable maintenance). Many design decisions faced during the construction of ACE were guided by experience gained In the development of previous expert systems. The most significant departure from "standard" expert system architectures, however, is ACE's use of a conventional data base management system as its primary source of Information Its primary sources of knowledge are the expert maintenance personnel, who previously were users of the database system I and prImers on maintenance analysis strategy The coupling of "data base" and "knowledge-base" demonstrates In a forceful way the manner In which an expert system can significantly enhance the throughput and quality of automatic maintenance support systems. Based on the success of these maintenance expert systems, explosive growth of knowledge-based expert maintenance programs is predicted. Forthcoming maintenance expert systems will assist In the repair of high capital cost equipment, for which down time is expensive or unacceptable, or for which competent repair personnel are In short supply.
The effects of omega-3 and omega-6 fatty acids on in vitro prostate cancer growth. (1996)

Dietary intake of essential fatty acids (EFA) may play a role in prostate cancer cell proliferation. Epidemiological studies have demonstrated that men whose dietary intake is high in omega-3 fatty acid (FA) composition have a lower incidence of clinical prostate cancer, suggesting that external factors such as diet may play an important role in development and growth of prostate cancer. Furthermore, in prostate cancer cell lines, omega-6 and omega-3 FAs have demonstrated promotional and inhibitory effects respectively. To investigate the effects of dietary fats on nontumorigenic prostate cell growth we conducted in vitro studies with human metastatic PC-3, LNCaP and TSU prostate cell lines, the rat metastatic Mat-Ly-Lu cell line and rat non-metastatic epithelial cell lines EPYP1, EPYP2 and EPYP3. Cell lines were treated with linoleic acid (LA), an omega-6 FA (n-6), as well as linolenic (LLA) and eicosapentaenoic (EPA) acids, which are both omega-3 FAs (n-3). All cell lines were treated with 10% and 0.5% serum supplemented media plus fatty acid for comparison. Our results demonstrate that linoleic acid(n-6) has promotional effects at doses of 1-100ng/ml in all cell lines with the exception of EPYPl. Experiments with linolenic acid (n-3) demonstrated consistent growth promotion in all cell lines examined with the exception of the EPYP2 cell line in which there was no significant effect. EPA had no effect in culture media supplemented with 10% serum, while in media containing 0.5% serum this FA demonstrated significant promotion in all human lines. Previous studies have indicated that EPA should inhibit human prostate cancer growth in vitro, however our results demonstrated promotion at low concentrations (lng/ml). At higher concentrations, EPA did inhibit prostate cell growth. These data indicate low levels of dietary fat, regardless of composition, may play a role in prostate cancer proliferation and could be an avenue for therapeutic intervention.
Selective oxidation and reduction of methionine residues in peptides and proteins by oxygen exchange between sulfoxide and sulfide. (1986)

Treatment of amino acids, peptides, and proteins with aqueous solution of dimethyl sulfoxide (Me2SO) and hydrochloric acid (HCl) resulted in the oxidation of methionine to methionine sulfoxide. In addition to methionine, SH groups are also oxidized, but this reaction proceeds after a lag period of 2 h. Other amino acids are not modified by aqueous Me2SO/HCl. The reaction is strongly pH-dependent. Optimal conditions are 1.0 M HCl, 0.1 M Me2SO, at 22 degrees C. The reaction exhibits pseudo-first order kinetics with Kobs = 0.23 +/- 0.015 M-1 min-1 at 22 degrees C. Incubation of methionine sulfoxide with dimethyl sulfide and HCl resulted in the conversion of methionine sulfoxide to methionine. This reaction is fast (t1/2 = 4 min at room temperature) and quantitative at relatively anhydrous condition (i.e. at H2O:concentrated HCl:dimethyl sulfide ratio of 2:20:1). Quantitative conversions of methionine sulfoxide back to methionine are obtained in peptides and proteins as well, with no observable other side reactions in amino acids and proteins. The wide applications of this selective oxidation and reduction of methionine residues are demonstrated and discussed.
How polarization-sensitive interneurones of crickets see the polarization pattern of the sky: a field study with an opto-electronic model neurone (1999)

Many insects gain directional information from the polarization pattern of the sky. Polarization vision is mediated by the specialized ommatidia of the dorsal rim area of the compound eye, which contains highly polarization-sensitive photoreceptors. In crickets Gryllus campestris, polarized light information conveyed by the dorsal rim ommatidia was found to be processed by polarization-opponent interneurones (POL-neurones). In this study, a field-proof opto-electronic model of a POL-neurone was constructed that implements the physiological properties of cricket POL-neurones as measured by previous electrophysiological experiments in the laboratory. Using this model neurone, both the strength of the celestial polarization signal and the directional information available to POL-neurones were assessed under a variety of meteorological conditions. We show that the polarization signal as experienced by cricket POL-neurones is very robust, both because of the special filtering properties of these neurones (polarization-antagonism, spatial low-pass, monochromacy) and because of the relatively stable e-vector pattern of the sky.
Simultaneous separation and quantification of free and metal-chelated protoporphyrins in blood by three-dimensional HPLC. (1994)

In this new method for simultaneous separation and quantification of free and metal-chelated porphyrins in blood, the porphyrins are extracted from blood samples with a mixture of diisopropylamine:water:methanol (25:100:900, by vol) and separated by HPLC elution. The data are collected in three-dimensional form with a microcomputer. This method permits a high recovery of protoporphyrin (PP) and Zn-chelated PP as well as heme from blood. By this method, the amounts of these analytes in erythrocytes from normal or abnormal subjects can be determined more accurately than by conventional methods.
Branch predictor guided instruction decoding (2006)

Fast instruction decoding is a challenge for the design of CISC microprocessors. A well-known solution to overcome this problem is using a trace cache. It stores and fetches already decoded instructions, avoiding the need for decoding them again. However, implementing a trace cache involves an important increase in the fetch architecture complexity. In this paper, we propose a novel decoding architecture that reduces the fetch engine implementation cost. Instead of using a special-purpose buffer like the trace cache, our proposal stores frequently decoded instructions in the memory hierarchy. The address where the decoded instructions are stored is kept in the branch prediction mechanism, enabling it to guide our decoding architecture. This makes it possible for the processor front-end to fetch already decoded instructions from memory instead of the original non-decoded instructions. Our results show that an 8-wide superscalar processor achieves an average 14% performance improvement by using our decoding architecture. This improvement is comparable to the one achieved by using the more complex trace cache, while requiring 16% less chip area and 21% less energy consumption in the fetch architecture.
2,5‐Di(<i>tert</i>‐butyl)‐1,4‐benzohydroquinone — a novel inhibitor of liver microsomal Ca<sup>2+</sup> sequestration (1987)

Treatment of rat liver microsomes with 2,5-di(tert-butyl)-1,4-benzohydroquinone caused a dose-related inhibition (Ki congruent to 1 microM) of ATP-dependent Ca2+ sequestration. This was paralleled by a similar impairment of the microsomal Ca2+-stimulated ATPase activity. In contrast, the hydroquinose failed to induce Ca2+ release from Ca2+-loaded liver mitochondria (supplied with ATP), and inhibited neither the mitochondrial F1F0-ATPase nor the Ca2+-stimulated ATPase activity of the hepatic plasma membrane fraction. The inhibition of microsomal Ca2+ sequestration was not associated with any apparent alteration of membrane permeability or loss of other microsomal enzyme activities or modification of microsomal protein thiols. These findings suggest that 2,5-di(tert-butyl)-1,4-benzohydroquinone is a potent and selective inhibitor of liver microsomal Ca2+ sequestration which may be a useful tool in studies of Ca2+ fluxes in intact cells and tissues.
Fibrin/Schwann Cell Matrix in Poly-Epsilon-Caprolactone Conduits Enhances Guided Nerve Regeneration (2004)

The goal of this study was to investigate if a three dimensional matrix, loaded homogeneously with Schwann cells and the neurotrophic factor LIF (leukemia inhibitory factor), enhances regeneration in a biodegradable nerve guidance channel as compared to non-structured cell suspensions. Therefore a 10 mm nerve gap in the buccal branch of the rat's facial nerve was bridged with tubular PCL (poly-epsilon-caprolactone) conduits filled with no matrix, Schwann cells, the three dimensional fibrin/Schwann cell matrix or the fibrin/Schwann cell matrix added with LIF Four weeks after the nerve defects were bridged histological and morphometric analyses of the implants were performed. In conclusion, the three dimensional fibrin/Schwann cells matrix enhanced the quantity and the quality of peripheral nerve regeneration through PCL conduits. The application of LIF prevented hyperneurotization. Therefore, tissue engineered fibrin/Schwann cells matrices are new invented biocompatible and biodegradable devices for enhancing peripheral nerve regeneration as compared to non-structured cell suspensions without neurotrophic factors.

The expression of Fc receptors for immunoglobulin G in human rectal epithelium (1991)

The rectal mucosa is one of the routes of transmission of the HIV virus, although the mechanism of transmission is unknown. We carried out an immunohistological investigation of human rectal epithelium to detect CD4 glycoprotein and Fc receptors (FcR) for immunoglobulin G which may be involved in HIV infection. CD4 was not detected by monoclonal antibodies (MAb) in normal rectal epithelial cells, although CD4+ mononuclear cells were found in the lamina propria of the rectum. FcR3 and FcR2 were, however, detected in surface or crypt epithelial cells of rectal mucosa, using MAb to CD16 and CD32, respectively. In addition, CD16 messenger RNA (mRNA) was found in surface and crypt epithelial cells by in situ hybridization using an RNA probe. FcR3 and FcR2 were also detected in fetal recto-colonic tissue by immunohistology, suggesting that these are constitutive receptors. FcR3 and FcR2 gene transcripts were then demonstrated in fetal recto-colonic tissue using the polymerase chain reaction to amplify a portion of FcR3 and FcR2 coding sequences in complementary DNA (cDNA) prepared from fetal RNA. These findings suggest the possibility that rectal transmission of HIV-antibody complexes might be facilitated by the expression of FcR3 and FcR2 in rectal epithelial cells.
A 14 b 35 MS/s SAR ADC Achieving 75 dB SNDR and 99 dB SFDR With Loop-Embedded Input Buffer in 40 nm CMOS (2015)

This paper presents a 14 bit 35 MS/s successive approximation register (SAR) ADC that achieves a nearly constant 74.5 dB peak SNDR up to Nyquist and an SFDR of 90/99 dB for inputs near Nyquist and at low-frequencies, respectively. The ADC employs a loop-embedded input buffer that shields the large sampling capacitor from the input and thereby eases the ADC drive requirements significantly. Since the buffer's nonlinearity is cancelled by the SAR operation, a pair of basic source followers can be used, adding only 12.5 mW (23% of the total power) to the power budget. The ADC includes a bandgap reference and a self-calibrated current steering DAC to close the SAR loop, which eliminates the need for a low-impedance off-chip reference. The design occupies 0.236 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> in 40 nm CMOS and consumes a total power of 54.5 mW from its 1.2/2.5 V supplies, leading to an SNDR-based Schreier FOM of 159.5 dB at Nyquist.

Hierarchical Retargetting of Fine Facial Motions (2004)

Abstract We present a novel technique for retargetting captured facial animation to new facial models. We use dense motion data that can express fine motions such as wrinkles. We use a normal mesh, which is a special multi‐resolution mesh, to represent source and target models. A normal mesh is defined by the base mesh and sequence of normal offsets from it. Our retargetting consists of two steps: base mesh and detail mesh retargetting. For base mesh retargetting, we use an example‐based technique to take advantage of the intuition of the user in specifying the similarity between source and target expressions. In detail mesh retargetting, the variations of normal offsets in the source mesh are hierarchically computed and transferred to the target mesh. Our retargetting scheme is able to produce robust and delicate results for unusual target models from highly detailed motion data.
