Control of Four-Wheel-Steering Vehicle Using GA Fuzzy Neural Network (2008)

In order to improve the handling and stability of four-wheel-steering (4WS) vehicle, a new 4WS intelligent control system with genetic algorithm (GA) fuzzy neural network (FNN) was put forward. According to the tire cubic formula, a vehicle nonlinear dynamics model was built. Then a vehicle model based on back-propagation (BP) network was identified from the vehicle dynamics. Next a fuzzy neural network controller was designed. Speed, steering angle of front wheel and lateral acceleration were taken as its input variables and steering angle of rear wheel was taken as its output variable. At last GA was used to optimize the fuzzy neural network controller. The results of computer simulation demonstrate that the 4WS intelligent control system with GA fuzzy neural network can markedly reduce the side slip angle and the yaw rate compared with linear 4WS control law and 2WS control law, the entire control system is robust, and the optimization by GA improves the control performance of controller and the design efficiency.
Nitric oxide synthase in skeletal muscle fibers: a signaling component of the dystrophin-glycoprotein complex. (1999)

The present review deals with the anatomical distribution, physiological importance, and pathological implications of the neuronal-type nitric oxide synthase (nNOS) in skeletal muscle. Throughout the body, nNOS is located beneath the sarcolemma of skeletal muscle fibers. In rodents, nNOS is enriched in type IIb muscle fibers, but is more homogenously distributed among type II and type I fibers in humans and subhuman primates. It is accumulated on the postsynaptic membrane at the neuromuscular junction. An increased concentration of nNOS is noted at the sarcolemma of muscle spindle fibers, in particular nuclear bag fibers, which belong to type I fibers. The association of nNOS with the sarcolemma is mediated by the dystrophin-glycoprotein complex. Specifically, nNOS is linked to alpha 1-syntrophin through PDZ domain interactions. Possibly, it also directly binds to dystrophin. The activity and expression of nNOS are regulated by both myogenic and neurogenic factors. Besides acetylcholine, glutamate has also been shown to stimulate nNOS, probably acting through N-methyl-D-aspartate receptors, which are colocalized with nNOS at the junctional sarcolemma. Functional studies have implicated nitric oxide as a modulator of skeletal muscle contractility, mitochondrial respiration, carbohydrate metabolism, and neuromuscular transmission. A clinically relevant aspect of nNOS is its absence from the skeletal muscle sarcolemma of patients with Duchenne muscular dystrophy (DMD). A concept is presented which suggests that, as a consequence of the disruption of the dystrophin-glyoprotein complex in DMD, nNOS fails to become attached to the sarcolemma and is subject to downregulation in the cytosol.
Video scene categorization by 3D hierarchical histogram matching (2009)

In this paper we present a new method for categorizing video sequences capturing different scene classes. This can be seen as a generalization of previous work on scene classification from single images. A scene is represented by a collection of 3D points with an appearance based codeword attached to each point. The cloud of points is recovered by using a robust SFM algorithm applied on the video sequence. A hierarchical structure of histograms located at different locations and at different scales is used to capture the typical spatial distribution of 3D points and codewords in the working volume. The scene is classified by SVM equipped with a histogram matching kernel, similar to. Results on a challenging dataset of 5 scene categories show competitive classification accuracy and superior performance with respect to a state-of-the-art 2D pyramid matching methods applied to individual image frames.
An information theoretic analysis on indoor PLC channel characterizations (2009)

Power-Line is recently considered as a future medium for the high rate transmissions. But the development of Power Line Communications (PLC) highly depends on the knowledge of the channel characterizations. For this reason, a large number of attentions have been payed on the PLC channel analysis using the measurements. This paper highlights an information theoretic analysis for indoor PLC channel environment investigation, wherein, the estimated channel entropy and the power delay spectrum are expected to give us much useful information to describe the indoor PLC channels. Moreover, the study on the PLC channel degree of freedom distribution and the discussion of choosing whether wide-band or multi-band are included in this paper.
[Effect of dibasol and ascorbic acid on the antiviral activity of human interferon in cell culture]. (1979)

The antiviral effect of human lymphocytic interferon was studied in the primary culture of human embryonic fibroblasts in the presence of dibazol and ascorbic acid. It was found that dibazol and ascorbic acid in concentrations of 5 and 10 gamma/ml respectively were capable of increasing the antiviral effect of human interferon in homological cells. The assays of 13 lots of interferon showed that its average titer in the experiments with ascorbic acid was 2.5 times higher than that in the control. The assays of 21 lots of interferon showed that its average titer in the experiments with dibazol was 3 times higher than that in the control. It is suggested that an increase in the protective properties of interferon in the presence of dibazol and ascorbic acid is connected with their capacity for stimulating the intracellular production of DNA and protein. The data obtained indicate that dibazol and ascorbic acid may be recommended in the complex of therapy and prophylaxis of antiviral infections.
Detection thresholds in car following situations and peripheral vision: implications for positioning of visually demanding in-car displays (1999)

Abstract This on-road study examined the effect of the positioning of an attentionally demanding in-car task on the driver's ability to detect the approach of a decelerating car ahead. Twelve participants aged between 19 and 27 years with an average of 18 170 km life-time driving experience drove 20 and 40 m behind a vehicle which decelerated from 50 km/h at ~0.7 m/s2 without braking. Detection thresholds for nine locations of a LED display were compared with thresholds when focusing on the car ahead. A strong inverse relationship was found between time-to-collision (TTC) and eccentricity of the task to the normal line of sight, with TTC decreasing from 6 to 8 s at 0° eccentricity to 4 s at 90°. The results suggest that there are optimal locations, in terms of detecting the deceleration of a car ahead, for positioning attentionally demanding in-car devices, and that there are some differences in detection thresholds for similar eccentricities in the vertical and horizontal peripheries of the eye.

Extending the HDP-CVD technology to the 90 nm node and beyond with an in-situ etch assisted (ISEA) HDP-CVD process (2003)

High density plasma chemical vapor deposition (HDP-CVD) technology is currently not able to provide the semiconductor industry with a void-free fill process for shallow trench isolation (STI) with 100 nm gap width and aspect ratios (AR) higher than 4:1. For the first time a method is shown, which can extend the well-known HDP-CVD technology to provide void-free gap fill to gap widths below 90 nm and AR higher than 6:1. Key to this is the addition of nitrogen trifluoride (NF/sub 3/) to the conventional silane/oxygen HDP-CVD chemistry. As a result of this component, an in-situ fluorine based isotropical oxide etch, gap fill capability will be improved. Compared to other fill alternatives a very good oxide quality is obtained for this process. The incorporated F and N show only a minor impact on film quality. The integration scheme does not need to be changed. Results from fully integrated DRAM wafers showed comparable yield to conventional HDP split groups with no additional reliability risk.
Quadriceps tendon-patellar bone autograft for anterior cruciate ligament reconstruction: a technical note. (2008)

The quadriceps tendon autograft can be used for primary and revision anterior cruciate ligament (ACL) reconstruction. Despite several successful clinical reports, graft fixation issues remain, and the ideal technique for fixation continues to be controversial. We present a technique of ACL reconstruction with quadriceps tendon autograft (QTA) using a patellar bone block. The tendon end is fixed in the femoral tunnel and the bone plug in the tibial tunnel using reabsorbable interference screws. The advantages of this technique are related to the increase in stiffness of the graft, the achievement of a more anatomic fixation, and a reduction in synovial fluid leakage.

And last it shows some results of the system to track the space objects.
A 150-MHz direct digital frequency synthesizer in 1.25- μm CMOS with -90-dBc spurious performance (1991)

A monolithic CMOS direct digital frequency synthesizer (DDFS) is presented which simultaneously achieves high spectral purity and wide bandwidth. Phase noise of the output sine wave is equivalent to or better than that of the 150-MHz reference clock. The synthesizer covers a bandwidth from DC to 75 MHz in steps of 0.035 Hz with a switching speed of 6.7 ns and a tuning latency of 13 clock cycles. An efficient look-up table method for calculating the sine function reduces ROM storage requirements by a factor of 128:1. All circuit designs are fully static and are tolerant to transistor threshold shifts caused by radiation or process variations. The DDFS was fabricated in a 1.25- mu m radiation-hardened double-level metal bulk P-well CMOS process which is tolerant to over 10/sup 6/ rd(Si) of total dose radiation. The die size is 195 mil*195 mil with a device count of 35,000 transistors. Power dissipation is 950 mW at a clock rate of 100 MHz.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Two distinct Ca-dependent K currents in bullfrog sympathetic ganglion cells. (1985)

Healthy bullfrog sympathetic ganglion cells often show a two-component afterhyperpolarization (AHP). Both components can be reduced or abolished by adding Ca-channel blockers or by removing external Ca. Application of a single electrode "hybrid clamp"--i.e., switching from current- to voltage-clamp at the peak of the AHP, reveals that the slow AHP component is generated by a small, slow, monotonically decaying outward current, which we call IAHP. IAHP is blocked by Ca-removal or by apamin and is a pure K current. It is slightly sensitive to muscarine and to tetraethylammonium ion but is much less so than muscarine-sensitive (IM) and fast Ca-dependent (IC) K currents. It also can be recorded in dual-electrode voltage-clamp experiments, where it is seen as a slow, small component of the outward tail current that follows brief depolarizations to 0 mV or beyond. IC is seen as an early, fast, large component of the same tail current. Both components are blocked by Ca removal, but only the IC component is blocked by low doses of tetraethylammonium ion. Thus, bullfrog ganglion cells exhibit two quite distinct Ca-dependent K currents, which differ in size, voltage-sensitivity, kinetics, and pharmacology. These two currents also play quite separate roles in shaping the action potential.
Regulation of Carbohydrate and Fat Metabolism During and After Exercise (1996)

During vigorous exercise, carbohydrate, in the form of muscle glycogen and blood glucose, is the primary energy source, whereas fatty acids play a secondary, carbohydrate-sparing role. In the postabsorptive state, nearly all of the carbohydrate used during exercise comes from muscle and liver glycogen. The size of these glycogen stores plays a major role in determining how long vigorous endurance exercise can be performed if other causes of fatigue, such as dehydration or heat exhaustion, are avoided. In a "fight or flight" situation, individuals whose muscles are glycogen depleted are helpless, as they are unable to either run or fight. The same is true of someone who has become markedly hypoglycemic as a result of liver glycogen depletion.
Active learning for node classification in assortative and disassortative networks (2011)

In many real-world networks, nodes have class labels or variables that affect the network's topology. If the topology of the network is known but the labels of the nodes are hidden, we would like to select a small subset of nodes such that, if we knew their labels, we could accurately predict the labels of all the other nodes. We develop an active learning algorithm for this problem which uses information-theoretic techniques to choose which nodes to explore. We test our algorithm on networks from three different domains: a social network, a network of English words that appear adjacently in a novel, and a marine food web. Our algorithm makes no initial assumptions about how the groups connect, and performs well even when faced with quite general types of network structure. In particular, we do not assume that nodes of the same class are more likely to be connected to each other - only that they connect to the rest of the network in similar ways.

A two-tier user simulation model for reinforcement learning of adaptive referring expression generation policies (2009)

We present a new two-tier user simulation model for learning adaptive referring expression generation (REG) policies for spoken dialogue systems using reinforcement learning. Current user simulation models that are used for dialogue policy learning do not simulate users with different levels of domain expertise and are not responsive to referring expressions used by the system. The two-tier model displays these features, that are crucial to learning an adaptive REG policy. We also show that the two-tier model simulates real user behaviour more closely than other baseline models, using the dialogue similarity measure based on Kullback-Leibler divergence.

High-frequency isolation UPS with novel SMR (2002)

This paper concerns a newly developed 2 to 5 kVA, high-frequency isolation type UPS (uninterruptible power system). This UPS features a novel SMR (switch mode rectifier) that is applied to the input converter section and a newly developed low-loss IGBT (insulated gate bipolar transistor) that is employed in both inverter and converter sections. The SMR, as a single converter, has functions for high-frequency isolation, enhancement of input power factor and stabilization of DC output voltage. In the case of a new type of DC-clamped SMR (DCC-SMR), the number of current flowing devices in the frequency changer has been reduced to 1/2 of those compared with systems using a conventional SMR, and simplification of the snubber discharge circuit has also been achieved. Owing to the above, this newly developed UPS not only has small volume and weight, about 1/2 of that of commercial frequency isolation type UPSs, but also provides high efficiency-at least equivalent to that of the latter UPS.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Influence of Gonadoliberin on the Differentiation of Rat Gonadotrophs: An in vivo and in vitro Study (1984)

The influence of gonadoliberin (GnRH) on the differentiation of rat gonadotrophs in early fetal life was studied both in vivo and in vitro by immunocytology with anti-porcine luteinizing hormone beta (pLH beta) serum. Adenohypophysial primordia explanted from 11 to 13 days of gestation were maintained in organ culture in synthetic Parker's 199 medium enriched with insulin (0.5 microgram/ml) and transferrin (5 micrograms/ml). Cultures lasted to approximate the usual gestation period (21 days). Synthetic GnRH (10(-9) or 10(-12) M) was added to the culture medium during the first day of culture only. In contrast to a previous report, immunoreactive cells were detected in the primordia explanted either at 11 or 12 days of gestation only when cultured in the presence of GnRH. The appearance of positive localization was seen by 17 days. No differences due to GnRH dosage were observed in the mean cytoplasmic area of the cells in the different experimental groups as seen at the equivalent of 21 days. GnRH was not effective in a medium deprived of insulin. GnRH, added 6 h before the end of the culture, could also release the secretory product of gonadotrophs which recently developed the presence of immunoreactive pLH beta material. In these conditions, GnRH was shown to enter the cells as observed by immunocytochemistry on sections obtained after cryoultramicrotomy. Endogenous GnRH was also detected by the same technique in fetal pituitary glands removed from 14 to 21 days of gestation. It was always localized in agranular cells and from 18 days in some granular cells considered as gonadotrophs.(ABSTRACT TRUNCATED AT 250 WORDS)
Resource Management and Adaptive Replication for Fault-Tolerant MAS (2010)

Abstract. Distributed cooperative applications are now increasingly being designed as MAS. Such applications may be massive, open and very dynamic: new agents can join or leave, they can change roles, strate-gies, etc. This characteristics create new challenges to the traditional approaches of fault-tolerance. In this paper, we focus on a replication-based preventive approach. The aim is to dynamically and automatically adapt the agent replication strategy (e.g. number of replicas and their location), in order to maximize the MAS reliability. We describe a nego-tiation protocol, supporting adaptive replication. This protocol provides a distributed solution that uses local decision but guarantees global MAS performances. We report on experimental results using a first implemen-tation of the protocol. 1
Electroabsorption in Al<i>y</i> Ga1−<i>y</i> As–Al<i>x</i> Ga1−<i>x</i> As double heterostructures (1973)

The electroabsorption observed in AlyGa1−yAs–Alx Ga1−xAs (y &lt; x) double heterostructures is strongly polarization dependent. The absorption of the TM mode which is polarized parallel to the electric heterojunction field is larger than that of the TE mode. This dichroism increases with decreasing photon energy for photon energies smaller than the band-gap energy. The absorption is very large (up to 100 cm−1 for −10 V applied bias) for photon energies within 60 meV of the band gap. This electroabsorption effect can be used to make light intensity modulators, photodetectors, and polarizers. Very efficient intensity modulation has been demonstrated. The power necessary for 90% modulation is in the order of 0.1 mW/MHz.
Real-Time Immune Monitoring to Guide Plasmid DNA Vaccination Schedule Targeting Prostatic Acid Phosphatase in Patients with Castration-Resistant Prostate Cancer (2014)

Repetitive immunization with a plasmid DNA vaccine was safe and elicited Th1-biased antigen-specific T cells that persisted over time. Modifications in the immunization schedule based on real-time immune monitoring did not increase the frequency of patients developing effector and memory T-cell responses with this DNA vaccine.
Cache investment (2000)

Emerging distributed query-processing systems support flexible execution strategies in which each query can be run using a combination of data shipping and query shipping. As in any distributed environment, these systems can obtain tremendous performance and availability benefits by employing dynamic data caching. When flexible execution and dynamic caching are combined, however, a circular dependency arises: Caching occurs as a by-product of query operator placement, but query operator placement decisions are based on (cached) data location. The practical impact of this dependency is that query optimization decisions that appear valid on a per-query basis can actually cause suboptimal performance for all queries in the long run. To address this problem, we developed Cache Investment - a novel approach for integrating query optimization and data placement that looks beyond the performance of a single query. Cache Investment sometimes intentionally generates a “suboptimal” plan for a particular query in the interest of effecting a better data placement for subsequent queries. Cache Investment can be integrated into a distributed database system without changing the internals of the query optimizer. In this paper, we propose Cache Investment mechanisms and policies and analyze their performance. The analysis uses results from both an implementation on the SHORE storage manager and a detailed simulation model. Our results show that Cache Investment can significantly improve the overall performance of a system and demonstrate the trade-offs among various alternative policies.
