A study on an algorithm of multisensor data fusion (2002)

Multisensor data fusion seeks to combine data from multiple sensors to perform inferences that may not be possible from a single sensor alone. The two main processes in multisensor data fusion system are the tracking and data fusion algorithms. A new hierarchical algorithm for the multisensor data fusion is proposed in the paper. The realization architecture for the new track fusion equations is also presented. The simulation results included in the paper indicate that the method is effective to the multisensor multitarget tracking problem.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Transform based and search aware text compression schemes and compressed domain text retrieval (2005)

In recent times, we have witnessed an unprecedented growth of textual in-formation via the Internet, digital libraries and archival text in many applications. While a good fraction of this information is of transient interest, useful information of archival value will continue to accumulate. We need ways to manage, organize and transport this data from one point to the other on data communications links with limited bandwidth. We must also have means to speedily find the information we need from this huge mass of data. Sometimes, a single site may also contain large collections of data such as a library database, thereby requiring an efficient search mechanism even to search within the local data. To facilitate the information retrieval, an emerging ad hoc standard for uncompressed text is XML which preprocesses the text by putting additional user defined metadata such as DTD or hyperlinks to enable searching with better efficiency and effectiveness. This increases the file size considerably, underscoring the importance of applying text compression.
A study on optimal termination target of synchronous H-ARQ for the next generation cellular system (2008)

In 3.9G cellular systems, which have many specific components, operators have to manipulate many parameters of each component. One of the critical parameters is the termination target of H-ARQ. It is supposed that the termination target influences system performance in terms of both throughput and delay because the termination target involves a trade-off between the gain of high modulation order and the loss of continuous resource assignment by H-ARQ. The link-level performance of turbo coded H-ARQ has already been reported, however, the influence of the termination target on system performance is still to be fully studied. The purpose of this study is to determine the optimal termination target and to examine which parameter influences sector throughput. It was found that the optimal termination target depends on the propagation model and average SINR. By selecting the optimal termination target, the system throughput can achieve 20 % gain compared to a system using a non-optimal termination target.
“Click” synthesis of small molecule–peptide conjugates for organelle-specific delivery and inhibition of lysosomal cysteine proteases (2010)

A click chemistry approach for the synthesis of small molecule inhibitor-peptide conjugates to achieve organelle-specific delivery has been developed. Biological testing showed that the inhibitor-Tat conjugate was successfully delivered to the lysosomes, leading to potent inhibition of lysosomal cysteine proteases in cultured cells.
An Engineered Kinetic Amplification Mechanism for Single Nucleotide Variant Discrimination by DNA Hybridization Probes (2016)

Even a single-nucleotide difference between the sequences of two otherwise identical biological nucleic acids can have dramatic functional consequences. Here, we use model-guided reaction pathway engineering to quantitatively improve the performance of selective hybridization probes in recognizing single nucleotide variants (SNVs). Specifically, we build a detection system that combines discrimination by competition with DNA strand displacement-based catalytic amplification. We show, both mathematically and experimentally, that the single nucleotide selectivity of such a system in binding to single-stranded DNA and RNA is quadratically better than discrimination due to competitive hybridization alone. As an additional benefit the integrated circuit inherits the property of amplification and provides at least 10-fold better sensitivity than standard hybridization probes. Moreover, we demonstrate how the detection mechanism can be tuned such that the detection reaction is agnostic to the position of the SNV within the target sequence. in contrast, prior strand displacement-based probes designed for kinetic discrimination are highly sensitive to position effects. We apply our system to reliably discriminate between different members of the let-7 microRNA family that differ in only a single base position. Our results demonstrate the power of systematic reaction network design to quantitatively improve biotechnology.

The artificial silicon retina in retinitis pigmentosa patients (an American Ophthalmological Association thesis). (2010)

ASR-implanted RP patients experienced prolonged neurotrophic rescue of vision. CGAT and CCT extended the range of acuity and color vision testing in low vision patients. ASR implantation may improve and prolong vision in RP patients.
The critical role of leukotriene B<sub>4</sub> in antigen‐induced mechanical hyperalgesia in immunised rats (2003)

1. We investigated the mediators responsible for mechanical hypersensitivity induced by antigen challenge in rats immunised with ovalbumin (OVA). 2. Challenge with OVA (12.5-100 micro g, intraplantar) caused a dose- and time-dependent mechanical hypersensitivity, which peaked 3 h after, decreased thereafter and reached control levels 24 h later. 3. Levels of TNFalpha, IL-1beta and cytokine-induced neutrophil chemoattractant 1 (CINC-1) were increased in paw skin after antigen challenge. 4. OVA-evoked hypersensitivity was partially inhibited (about 51%) by pretreatment with anti-TNFalpha, IL-1beta and IL-8 sera or with IL-1 receptor antagonist (IL-1ra), but not anti-NGF serum. Pretreatment with thalidomide (45 mg kg(-1)) or pentoxifylline (100 mg kg(-1)) also partially inhibited the hypersensitivity at 1-3 h after challenge. 5. Pretreatment with indomethacin (5 mg kg(-1)) or atenolol (1 mg kg(-1)) reduced the OVA-induced hypersensitivity at 1 and 3 h, but not at 5 h after challenge, while the combination of B(1) and B(2) bradykinin receptor antagonists was ineffective over the same times. 6. Pretreatment with MK886 (5-lipoxygenase-activating protein inhibitor, 3 mg kg(-1)), CP 105696 (LTB(4) receptor antagonist; 3 mg kg(-1)) or dexamethasone (0.5 mg kg(-1)) inhibited the hypersensitivity from 1 to 5 h. Furthermore, LTB(4) levels were increased in the paw skin of challenged rats. 7. In conclusion, our results suggest that the TNFalpha-, IL-1beta- and CINC-1-driven release of prostaglandins, sympathetic amines and LTB(4) mediates the first 3 h of mechanical hypersensitivity induced by antigen challenge in rats. At 5 h after OVA administration, although TNFalpha has some role, LTB(4) is the critical nociceptive mediator.
Near-Minimum Bit-Error Rate Equalizer Adaptation for PRML Systems (2007)

Receivers for partial response maximum-likelihood systems typically use a linear equalizer followed by a Viterbi detector. The equalizer tries to confine the channel intersymbol interference to a short span in order to limit the implementation complexity of the Viterbi detector. Equalization is usually made adaptive in order to compensate for channel variations. Conventional adaptation techniques, e.g., LMS, are, in general, suboptimal in terms of bit-error rate (BER). In this paper, we present a new equalizer adaptation algorithm that seeks to minimize the BER at the Viterbi detector output. The algorithm extracts information from the sequenced amplitude margin (SAM) histogram and incorporates a selection mechanism that focuses adaptation on particular data and noise realizations. The selection mechanism is based on the reliability of the add compare select (ACS) operations in the Viterbi detector. From a complexity standpoint, the algorithm is essentially as simple as the conventional LMS algorithm. Moreover, we present a further simplified version of the algorithm that does not require any hardware multiplications. Simulation results, for an idealized optical storage channel, confirm a substantial performance improvement relative to existing adaptation algorithms.
Copper wiring encapsulation at semi-global level to enhance wiring and dielectric reliabilities for next-generation technology nodes (2009)

The semi-global level is rather different from the intermediate level in terms of wiring scale and types of interlayer dielectrics, which has an impact on the encapsulation capability of MnO. The difference in both levels, therefore, requires major changes of the processes such as the deposition conditions of CuMn seed and capping film. We successfully enhanced wiring and dielectric reliability at the semi-global level as well as at the intermediate level in 45-nm-node technology. For electromigration and dielectric stability, MnO segregated along the outline of the Cu wiring increases activation energy and voltage acceleration factor by 54 and 47%, respectively. These increases effectively enhance the maximum current density and the expected interlayer dielectric lifetime by factors of 28 and 70, compared to those of a control sample.
Influence of excitation power and temperature on photoluminescence in InGaN/GaN multiple quantum wells (2012)

Excitation power and temperature dependences of the photoluminescence (PL) spectra are studied in InGaN/GaN multiple quantum wells (MQWs). The excitation power dependences of the PL peak energy and linewidth indicate that the emission process of the MQWs is dominated first by the Coulomb screening effect and then by the localized states filling at low temperature, and that the nonradiative centers are thermally activated in low excitation range at room temperature. The anomalous temperature dependences of the peak energy and linewidth are well explained by the localized carrier hopping and thermalization process, and by the exponentially increased density of states with energy in the band tail. Moreover, it is also found that internal quantum efficiency is related to the mechanism conversion from nonradiative to radiative mechanism, and up to the carriers escaping from localized states.
Hyperlactataemia and Metabolic Acidosis during Haemofiltration Using Lactate-Buffered Fluids (1991)

We have investigated the effect of an exogenous lactate load given during machine haemofiltration treatment in 22 patients with acute renal failure and 12 patients with chronic renal failure, without any overt evidence of liver disease. Hyperlactataemia occurred in all patients, but the expected changes in acid base status, an increase in bicarbonate and a reduction in arterial hydrogen ions were observed in less than 40% of the treatments in the acute renal failure group. Ultrafiltrate losses of lactate and bicarbonate could not alone explain the changes in acid-base status. There was a positive correlation between the increase in arterial lactate and hydrogen ion concentrations, r = 0.52, p less than 0.01. Lactate accumulation in patients at, or close to, their threshold for lactate utilisation may result in further depression of cardiac function and peripheral lactate utilisation. Hyperlactataemia due to use of lactate-based dialysis/haemofiltration solutions in critically ill patients may result in a worsening of the acid-base status, and arterial pH should be monitored so that bicarbonate solutions can be substituted if the changes are progressive.
8-channel WDM silicon photonics transceiver with SOA and semiconductor mode-locked laser (2018)

We demonstrate an integrated 8 by 14 Gbps dense wavelength division multiplexed silicon photonics transceiver that makes use of an external mode-locked laser as a light source and a single semiconductor optical amplifier for post-modulation signal amplification. Remaining components necessary for modulation, filtering and (de‑)multiplexing are monolithically integrated in a single chip. In all system experiments, all eight channels are jointly operated with independent data streams in order to include impairments arising out of nonlinear effects inside the SOA while benchmarking the system performance. The transmitter, measured with a commercial reference receiver, supports on-off keying data transmission with an uncorrected BER ranging between 1e-5 and 5e-7 for all channels in back-to-back configuration and between 8e-4 and 1e-5 after 10 km transmission (both PRBS 2<sup>31</sup>-1). The three best channels of the full link consisting in the silicon photonics transmitter operated with the silicon photonics receiver in back-to-back configuration maintain a BER better than the targeted 5e-5. Based on link budget modeling, we expect this target to be reached for all 8 channels pending improvement of the receiver offset compensation loop.
Hydrous metal oxide-supported catalysts (1990)

This report describes the development of the following new catalytic materials based on hydrous metal oxide (HMO) ion exchange materials: Na-Ti, Nb, Zr, and mixtures of hydrated silica with hydrous Ti-oxide. HMO's provide a versatile system for the preparation of heterogeneous catalysts. The preparation chemistry allows synthesis of catalysts that can be tailored to particular processes with respect to both chemical and physical properties. Bulk catalysts with surface areas over 300 m{sup 2}/g and pore volumes up to 0.4 cc/g as well as thin films of the HMO materials can be prepared on supports having a wide range of catalytically important physical properties. This report, the first of two parts, presents research performed to date regarding the preparation chemistry, and physical and chemical properties of HMO materials which may be used to develop heterogeneous catalysts for direct coal liquefaction processes. During the course of this work, new ideas for research areas relative to direct coal liquefaction were briefly explored. Two of them that merit further work, catalyst-anchored hydrogen donors and alkoxide-derived crystalline titanate compounds, are briefly described. 25 refs., 34 figs., 8 tabs.
Bradykinin potentiates cytokine‐induced prostaglandin biosynthesis in osteoblasts by enhanced expression of cyclooxygenase 2, resulting in increased RANKL expression (2007)

Kinin B1 and B2 receptors synergistically potentiate IL-1- and TNFalpha-induced PG biosynthesis in osteoblasts by a mechanism involving increased levels of COX-2, resulting in increased RANKL. The synergistic stimulation is dependent on NF-kappaB and MAP kinases. These mechanisms might help to explain the enhanced bone resorption associated with inflammatory disorders, including that in rheumatoid arthritis.
Cingulin and paracingulin show similar dynamic behaviour, but are recruited independently to junctions (2010)

Cingulin (CGN) and paracingulin (CGNL1) are structurally related proteins that regulate Rho family GTPases by recruiting guanine nucleotide exchange factors to epithelial junctions. Although the subcellular localization of cingulin and paracingulin is likely to be essential for their role as adaptor proteins, nothing is known on their in vivo localization, and their dynamics of exchange with the junctional membrane. To address these questions, we generated stable clones of MDCK cells expressing fluorescently tagged cingulin and paracingulin. By FRAP analysis, cingulin and paracingulin show a very similar dynamic behaviour, with recovery curves and mobile fractions that are distinct from ZO-1, and indicate a rapid exchange with a cytosolic pool. Interestingly, only paracingulin, but not cingulin, is peripherally localized in isolated cells, requires the integrity of the microtubule cytoskeleton to be stably anchored to junctions, and associates with E-cadherin. In contrast, both proteins require the integrity of the actin cytoskeleton to maintain their junctional localization. Although cingulin and paracingulin form a complex and can interact in vitro, the junctional recruitment and the dynamics of membrane exchange of paracingulin is independent of cingulin, and vice-versa. In summary, cingulin and paracingulin show a similar dynamic behaviour, but partially distinct localizations and functional interactions with the cytoskeleton, and are recruited independently to junctions.

Color control of a lighting system using RGBW LEDs (2010)

A lighting system is proposed to render objects under a variety of colored illumination. The proposed system is constructed with a LED unit, white diffusion filters, dimmers, and a personal computer as a controller. The LED unit is composed of four kinds of color LED lamps which are 12 red (R), 14 green (G), 12 blue (B) and 10 white (W) colors. The LED lamps have a linear input-output relationship and a larger color gamut than Adobe RGB. Since the lighting system has an independent white light source, white illumination can be produced using the white light source and a mixture of RGB primary sources. Therefore, to determine illumination color we have to solve a mapping problem from 3D color space to 4D space of RGBW digital values. This paper proposes an effective algorithm for determining the digital control signals of the RGBW lights, so that colored light is generated with arbitrary (x, y) chromaticity and luminance value Y. The performance of proposed method is examined in an experiment, where the accuracy of the colored light is evaluated with regard to the CIE color difference.
THE EFFECTS OF A VANED DIFFUSER PROFILE ON THE PERFORMANCE OF AN INTEGRATED HEART-LUNG ASSIST DEVICE (2003)

The integrated heart-lung assist device (IHLAD) has a composite structure of a centrifugal pump and a cylindrically located hollow fiber bundle to realize quick setting-up and improved mobility. Implementation of a vaned diffuser between the centrifugal pump and the hollow-fiber unit remarkably enhanced the gas-exchange efficiency. In this study, the optimum profile of the vaned diffuser was investigated especially to reduce the blood damage. A visualization using high-speed video was applied to identify flow phenomena having close relationships with hemolysis. Periodic alternating flow known as rotating stall was observed, which could augment hemolysis by the increased chances for blood cells to pass through the intensive flow area such as diffuser tips. To reduce rotating stall, vane number was reduced from 7 to 5. The effect of vane profile modification was evaluated by hemolysis testings at 5 L/min against the pressure head of 300 mmHg. The amount of hemolysis in the form of NIH was 0.177 for 7 vanes and 0.040 for 5 vanes. The attempt to reduce rotating stall was also carried out by changing the gap between the impeller and the diffuser vanes. Hemolysis testings were performed to compare the test rigs having several gap clearances (0.5, 1,2,3 mm). The gap size of 2 mm indicated the lowest NIH value of 0.007 while the current 3 mm showed NIH of 0.009. In conclusion, the performance of IHLAD in terms of hemolysis could be successfully improved by optimization of flow passages of the vaned diffuser.
Modelling of Lamb waves for damage detection in metallic structures: Part II. Wave interactions with damage (2003)

Lamb waves have shown great potential for structural health monitoring. The technique is based on guided ultrasonic waves introduced into a structure at one point and sensed at a different location. Damage in a structure is identified by a change in the output signal. However, previous studies show that even simple structural configurations can lead to complex response signals. Therefore a knowledge and understanding of wave propagation can ease the interpretation of damage detection results. This paper reports an application of the local interaction simulation approach for Lamb wave propagation modelling in metallic structures. The focus of the analysis is on two-dimensional wave interactions with slot-type defects. The method shows the potential for complex modelling of acousto-ultrasonic waves in damage detection applications.
A synthetic review of notoedres species mites and mange (2016)

Notoedric mange, caused by obligately parasitic sarcoptiform Notoedres mites, is associated with potentially fatal dermatitis with secondary systemic disease in small mammals, felids and procyonids among others, as well as an occasional zoonosis. We describe clinical spectra in non-chiropteran hosts, review risk factors and summarize ecological and epidemiological studies. The genus is disproportionately represented on rodents. Disease in felids and procyonids ranges from very mild to death. Knowledge of the geographical distribution of the mites is highly inadequate, with focal hot spots known for Notoedres cati in domestic cats and bobcats. Predisposing genetic and immunological factors are not known, except that co-infection with other parasites and anticoagulant rodenticide toxicoses may contribute to severe disease. Treatment of individual animals is typically successful with macrocytic lactones such as selamectin, but herd or wildlife population treatment has not been undertaken. Transmission requires close contact and typically is within a host species. Notoedric mange can kill half all individuals in a population and regulate host population below non-diseased density for decades, consistent with frequency-dependent transmission or spillover from other hosts. Epidemics are increasingly identified in various hosts, suggesting global change in suitable environmental conditions or increased reporting bias.
