A low-power baseband receiver IC for frequency-hopped spread spectrum applications (2002)

A baseband receiver IC which will be incorporated into a monolithic CMOS 900 MHz frequency-hopped spread spectrum (FH/SS) transceiver is described. The chip performs noncoherent binary/quaternary frequency shift keying (FSK) demodulation, equal-gain diversity combining of dual antenna branches, and symbol and frequency synchronization. The chip also accommodates variable data rates from 2-160 kbps, programmable hop rates, and tunable bandwidth of loop filters. The die area of this 1-/spl mu/m CMOS chip is 5.4 mm /spl times/5.4 mm with a power consumption of less than 6 mW from a 3-V supply.
Cyclic AMP and Ca2+-activated K+ transport in a human colonic epithelial cell line. (1985)

Addition of either vasoactive intestinal peptide (VIP) or the Ca2+ ionophore, A23187, to confluent monolayers of the T84 epithelial cell line derived from a human colon carcinoma increased the rate of 86Rb+ or 42K+ efflux from preloaded cells. Stimulation of the rate of efflux by VIP and A23187 still occurred in the presence of ouabain and bumetanide, inhibitors of the Na+,K+-ATPase and Na+,K+,Cl- cotransport, respectively. The effect of A23187 required extracellular Ca2+, while that of VIP correlated with its known effect on cyclic AMP production. Other agents which increased cyclic AMP production or mimicked its effect also increased 86Rb+ efflux. VIP- or A23187-stimulated efflux was inhibited by 5 mM Ba2+ or 1 mM quinidine, but not by 20 mM tetraethylammonium, 4 mM 4-aminopyridine, or 1 microM apamin. Under appropriate conditions, VIP and A23187 also increased the rate of 86Rb+ or 42K+ uptake. Stimulation of the initial rate of uptake by either agent required high intracellular K+ and was not markedly affected by the imposition of transcellular pH gradients. The effect of A23187, but not VIP or dibutyryl cyclic AMP, was refractory to depletion of cellular energy stores. A23187-stimulated uptake was not significantly affected by anion substitution, however, stimulation of uptake by VIP required the presence of a permeant anion. This result may be due to the simultaneous activation of a cyclic AMP-dependent Cl- transport system. The kinetics of both VIP- and A23187-stimulated uptake and efflux were consistent with a channel-rather than a carrier-mediated K+ transport mechanism. The results also suggest that cyclic AMP and Ca2+ may activate two different kinds of K+ transport systems. Finally, both transport systems have been localized to the basolateral membrane of T84 monolayers, a result compatible with their possible regulatory role in hormone-activated electrogenic Cl- secretion.
Detection and recognition of correction utterance in spontaneously spoken dialog (2003)

Recently, the performance of speech recognition was drastically improved, and the products with the interface based on speech recognition have been realized. However, when we communicate with computers through a speech interface, misrecognition is inevitable, and it is difficult to recover from it because of the immaturity of the interface. Users try to recover from misrecognition by a repetition of the same content. So, the detection of user’s repetition is helpful for a system to detect its misunderstanding, and to recover from the misrecognition. In this paper, we assume the utterance which includes repetitions a correction and propose a method to detect correction utterances in spontaneously spoken dialog using a word spotting based on DTW (dynamic time warping) and N -best hypotheses overlapping measure. As a result, we achieved recall rate of 92.7% and precision of 89.1%. Moreover, we tried to improve recognition accuracy using the detection. Using the choice of vocabulary and grammar setup based on the detection, we achieved improvement in recognition performance from 42.7% to 50.0% for correction utterance and from 70.5% to 77.9% for non-correction utterance.
Effect of intravenous alfuzosin on urethral pressure in patients with neurogenic bladder dysfunction (1996)

In order to assess the ability of a single intravenous (i.v.) injection of alfuzosin, a selective alpha-1 blocker, in reducing high urethral tone in patients with symptomatic neurogenic bladder dysfunction (NBD), 163 patients (mean maximal urethral pressure [MUP] 108 +/- 46 cm H2O) were enrolled in a double-blind, placebo-controlled, parallel-group trial and were randomly allocated to receive 0.5 mg (n = 45), 1 mg (n = 41), 2 mg (n = 39) alfuzosin or placebo (n = 38). The decrease in MUP was dose-dependent and statistically significant (P < or = 0.05) for 1 and 2 mg alfuzosin (respectively, 43 +/- 28 cm H2O and 46 +/- 27 cm H2O decreases vs. baseline) in comparison with placebo (23 +/- 30 cm H2O). The 2 mg dose level was the most effective leading to a > or = 30 or 50% decrease in MUP in, respectively, 69 and 44% of patients. The safety of all three alfuzosin dose levels was satisfactory and comparable to placebo. I.v. alfuzosin induces, in a dose-related manner, a clinically significant decrease in urethral pressure in patients with NBD and high urethral tone, and may be safely used as a pharmacological test as part of an urodynamic investigation.
Deep brain stimulation for treatment-resistant depression (2014)

Major depressive disorder (MDD) is a prevalent, disabling and costly neuropsychiatric syndrome. MDD is defined by episodes of low mood (nearly all day, every day) or anhedonia (inability to experience pleasure) combined with several other emotional, somatic and cognitive symptoms, including decreased or increased sleep, decreased or increased appetite, low energy, increased or decreased psychomotor activity, decreased cognitive function, guilt and a reduced desire to live (manifesting as thoughts of death, suicidal ideation or suicide attempts) (Box 15.1) [1]. MDD is one of the most common medical disorders, with a lifetime US prevalence of at least 17% and a 1-year prevalence of at least 7% [2]. Depression is the leading cause of years lost due to disability worldwide and the third overall contributor to worldwide burden of disease; however, depression is currently the primary contributor to burden of disease in high- and middle-income countries [3]. MDD is associated with an increased risk for suicide, but may also increase all-cause mortality [4].
[MicroRNA differential expression profile during differentiation of embryonic stem cells towards hepatocytes induced by sodium butyrate]. (2008)

During the course of embryonic stem cells differentiation towards hepatocytes induced by sodium butyrate, histone deacetylase and its relevant microRNAs may play important roles in cell differentiation.
Binding of APC to the Human Homolog of the <b> <i>Drosophila</i> </b> Discs Large Tumor Suppressor Protein (1996)

The adenomatous polyposis coli gene (APC) is mutated in familial adenomatous polyposis and in sporadic colorectal tumors, and its product binds to the adherens junction protein beta-catenin. Overexpression of APC blocks cell cycle progression. The APC-beta-catenin complex was shown to bind to DLG, the human homolog of the Drosophila discs large tumor suppressor protein. This interaction required the carboxyl-terminal region of APC and the DLG homology repeat region of DLG. APC colocalized with DLG at the lateral cytoplasm in rat colon epithelial cells and at the synapse in cultured hippocampal neurons. These results suggest that the APC-DLG complex may participate in regulation of both cell cycle progression and neuronal function.
Do changes in lifestyle engagement moderate cognitive decline in normal aging? Evidence from the Victoria Longitudinal Study. (2011)

The results support the dual contention that (a) lifestyle engagement may buffer some of the cognitive changes observed in late life, and (b) persons who are exhibiting poorer cognitive performance may also relinquish some lifestyle activities.
A Comparison of Bus Architectures for Safety-Critical Embedded Systems (2003)

Abstract. Embedded systems for safety-critical applications often integrate multiple “functions ” and must generally be fault-tolerant. These requirements lead to a need for mechanisms and services that provide protection against fault propagation and ease the construction of distributed fault-tolerant applications. A number of bus architectures have been developed to satisfy this need. This paper reviews the requirements on these architectures, the mechanisms employed, and the services provided. Four representative architectures (SAFEbus TM, SPIDER, TTA, and FlexRay) are briefly described. 1
RANTES, Macrophage‐Inhibitory Protein 1𝛂, and the Eosinophil Product Major Basic Protein Are Released into Upper Respiratory Secretions during Virus‐Induced Asthma Exacerbations in Children (1999)

The presence of cytokines and the toxic eosinophil granule product major basic protein (MBP) was investigated in nasal aspirates from children with naturally occurring virus-induced asthma exacerbations and compared with levels in nasal aspirates taken from the same children when asymptomatic. Increased levels of MBP accompanied by increased levels of the chemokines RANTES and macrophage-inhibitory protein 1alpha were observed in nasal aspirates from children during the virus-induced exacerbations. Granulocyte-macrophage colony-stimulating factor was mostly undetectable in samples obtained during both symptomatic and asymptomatic periods. Interleukin-5 levels were low, but tended to increase in samples from symptomatic children. These data confirm that the eosinophil product MBP and the eosinophil chemoattractant chemokines RANTES and macrophage-inhibitory protein 1alpha are increased in upper respiratory viral infections associated with asthma exacerbations and suggest an important role for these chemokines in regulating eosinophil influx and activation. These chemokines may represent targets for therapeutic intervention in virus-induced asthma exacerbations.
Eigenschaften einiger Störstellenkomplexe von Zink in Silizum (1982)

Mit den Methoden DLTS und TSCa werden die Eigenschaften einiger Ionenpaare zwischen den Donatoren und Doppeldonatoren der 3d-Gruppe und dem Doppelakzeptor Zink untersucht. Für die Donatoren Cr+, Fe+ werden Akzeptorniveaus in hoher Konzentration – wahrscheinlich verursacht durch die Paare (Cr+Zn−−), (Fe+Zn−−) – bei Ec − 0,10 eV, Ec − 0,47 eV beobachtet. Die Einfangkoeffizienten für Elektronen liegen bei r ≈ 3 × 10−8 (Cr, T = 77 K) und 2 × 10−9 cm3s−1 (Fe, T = 250 K). Ein zweites Niveau mit niedriger Konzentration bei Ec − 0,58 eV (Cr) oder Ev + 0,17 eV (Fe) wird möglicherweise durch Paare der Form (DZn−−) oder durch substituierte Ionen verursacht. Für die Doppeldonatoren V++, Mn++ werden Donatorniveaus bei Ev − 0,29 eV, Ev + 0,18 eV mit Löcher-Einfangkoeffizienten bei 1 × 10−8 (V, T = 200 K), 2 × 10−8 cm3 s−1 (Mn, T = 90 K) beobachtet. Aus einer ersten Ermittlung der Massenwirkungskonstante für den (VZn)-Komplex folgt als Bindungsenergie 2,7 eV. Dieser hohe Wert kann mit der Paarstruktur (V++Zn−−) erkärt werden. The properties of some ion pairs between donors or double donors of the 3d group and the double acceptor zinc are investigated by DLTS and TSCa techniques. For the donors Cr+, Fe− acceptor levels with high concentrations are found at Ec − 0.10 eV, Ec − 0.47 eV possibly caused by the pairs (Cr+Zn−−), (Fe+Zn−−). The capture coefficients for electrons lies at r ≈ 3 × 10−8 (Cr, T = 77 K) and 2 × 10−9 cm3s−1 (Fe, T = 250 K). A second level with a lower concentration at Ec − 0.58 eV (Cr) or Ev + 0.17 eV (Fe) is possibly caused by pairs of the structure (D+2Zn−) or the substitutional ions. For the double donors V++, Mn++ donor levels at Ev + 0.29 eV, Ev + + 0.18 eV with capture coefficients for holes of about 1 × 10−8 (V, T = 200 K), 2 × 10−8 cm3 s−1 (Mn, T = 90 K) are observed. From a first estimation of the equilibrium constant for the (VZn)-complex a binding energy of 2.7 eV is determined. It appears that this high value can be explained with the pair structure (V++Zn−).
A novel formulation of an ophthalmic beta-adrenoceptor antagonist. (1992)

To minimize ocular discomfort while maintaining efficacy, a delivery system for a topical cardioselective beta-adrenoceptor antagonist, betaxolol was developed. Betaxolol was formulated at 0.25% concentration in a cationic exchange resin, as a suspension. A polyacrylic acid polymer was added to increase viscosity and to increase residence time in the cul-de-sac. No significant settling was observed throughout a four-week observation period. Thus, resuspension of the formulation by frequent shaking was not required for uniformity. In rabbits, the ocular bioavailability of 0.25% betaxolol suspension was equivalent to that of 0.5% betaxolol solution.

Effect of Sorption on Mineralization of Low Concentrations of Aromatic Compounds in Lake Water Samples (1982)

Montmorillonite-benzylamine complexes were formed immediately upon addition of 20 pg to 20 mug of amine per ml of suspensions containing the clay. The extent of amine sorbed was a linear function of equilibrium amine concentration in lake water. Increases in the clay concentration decreased the percentage of the organic compound that was mineralized at amine levels of 20 pg to 200 ng, but not at 20 mug/ml. A larger percentage of the chemical was released from the complex during mineralization in the presence of high clay concentrations than in the presence of low clay concentrations. The rates of desorption and mineralization increased linearly with benzylamine levels up to 200 ng/ml. Montmorillonite did not enhance mineralization rates at amine levels of 200 ng/ml or lower, but it was stimulatory at 20 mug/ml. Except at high amine and clay concentrations, mineralization was more rapid than desorption during the early periods of decomposition when the amine concentration in solution was relatively high. However, relative to the microbial demand, desorption was more rapid during later periods of decomposition when the amine level in solution was very low. Mineralization of benzoate was not usually affected by montmorillonite, kaolinite, or glass beads. More than 90% of the carbon from benzylamine and benzoate was often mineralized when the substrate concentration was 250 ng/ml or less. After incubation of the chemical in lake water, none of the radioactivity from benzylamine was in the particulate fraction containing natural sediment and microbial cells. The data indicate that clay may have a significant effect on the microbial decomposition of low concentrations of certain organic compounds.
Cloning of the Thaumatin I cDNA and Characterization of Recombinant Thaumatin I Secreted by <i>Pichia pastoris</i> (2007)

Thaumatin is a sweet-tasting protein comprising a mixture of some variants. The major variants are thaumatins I and II. Although the amino acid sequence of thaumatin I was known and the nucleotide sequence of cDNA of thaumatin II was elucidated, the nucleotide sequence of thaumatin I has been controversial. We have cloned two thaumatin cDNAs from the fruit of Thaumatococcus daniellii Benth. One is the same nucleotide sequence as that of thaumatin II already reported, and the other is a novel nucleotide sequence. The amino acid sequence deduced from the novel cDNA was the same amino acid sequence as that of thaumatin I, the only exception being the residue at position 113 (Asp instead of Asn), indicating that the novel thaumatin cDNA is that for thaumatin I. This thaumatin I cDNA was transformed into Pichia pastoris X-33, and the recombinant thaumatin I expressed was purified and characterized. The threshold value of sweetness of the recombinant thaumatin I was the same as that of the plant thaumatin I, although several unexpected amino acid residues were attached to the N-terminal of the recombinant thaumatin I. These indicate that the N-terminal portion of thaumatin is not critical for the elicitation of sweetness.
Turbo Equalization of Non-Linear Satellite Channels Using Soft Interference Cancellation (2008)

Satellite communication channels can be well described as non-linear functions with memory. The Volterra series representation provides accurate modeling of satellite channel dynamics, and thus, it constitutes a widely used approach to mathematically describe them. In this work, iterative correction of the non-linear distortion introduced by such channels is considered, by employing a soft interference canceller operating in a turbo equalization framework.
Hypnosis as a window on regression. (1988)

A family of test adequacy criteria for database-driven applications (2003)

Although a software application always executes within a particular environment, current testing methods have largely ignored these environmental factors. Many applications execute in an environment that contains a database. In this paper, we propose a family of test adequacy criteria that can be used to assess the quality of test suites for database-driven applications. Our test adequacy criteria use dataflow information that is associated with the entities in a relational database. Furthermore, we develop a unique representation of a database-driven application that facilitates the enumeration of database interaction associations. These associations can reflect an application's definition and use of database entities at multiple levels of granularity. The usage of a tool to calculate intraprocedural database interaction associations for two case study applications indicates that our adequacy criteria can be computed with an acceptable time and space overhead.
Stereo disparity calculation in real-world scenes with Informative Image Partitioning (2010)

Despite their presence in almost all real-world navigational environments, finding stereo disparity in large, weakly textured regions is a difficult task. In this paper, we present a method which constructs a novel segmentation of an image into separate planar regions prior to disparity calculation. This segmentation allows us to fit planar models to disparity estimates calculated using a graph cut approach within each segment, producing smooth, accurate disparity maps in ordinarily difficult areas. Our method achieves good results using intensity features in a variety of indoor and outdoor navigational scenes. A comparison of our results with other benchmark approaches is presented, in which the advantages of our technique can be clearly seen.
INNERVATION BOTH OF PERI‐ORBITAL STRUCTURES AND OF THE HEART BY THE CERVICAL SYMPATHETIC NERVES IN MOUSE, RAT, GUINEA‐PIG, RABBIT AND CAT (1975)

1 In anaesthetized rats electrical stimulation of the intact cervical sympathetic nerve produced frequency-dependent lower eyelid contractions and tachycardia. 2 The tachycardia was caused by excitation of efferent fibres since it was equally evident in the pithed rat preparation, and the right nerve was more effective than the left. By contrast, no differences were seen between the responses to right and left vagal stimulation in either rats or rabbits. 3 Guanethidine inhibited both cardiac and eyelid responses, propranolol only the former and phentolamine only the latter, therby revealing the adrenergic nature of the nerves. Hexamethonium caused partial inhibition and the block was intensified by atropine. 4 The inferior eyelid of mice, guinea-pigs and rabbits as well as the nictitating membrane of rabbits and cats were contracted by cervical sympathetic nerve stimulation. In these species too, tachycardia occurred; this was more pronounced with the right than the left sympathetic nerve. The order of cardiac responsiveness was mouse greater than rat greater than guinea-pig greater than rabbit greater than cat. 5 In guinea-pigs histamine-induced bronchoconstriction was reduced by cervical sympathetic nerve stimulation. 6 That discrete cardiac pathways exist in the cervical sympathetic nerves is suggested by the reproducibility of the effects within any one species. The accessibility of the nerves greatly simplifies the examination of drugs in vivo on two different structures innervated by the sympathetic nervous system.
An iron-antagonized fungistatic agent that is not required for iron assimilation from a fluorescent rhizosphere pseudomonad (1988)

Fluorescent rhizosphere Pseudomonas sp. strain NZ130 promotes plant growth, and may do so in part because of its production of a growth inhibitory factor that is active against phytopathogenic fungi. Analysis of the inhibitory factor that is active against the phytopathogen Pythium ultimum showed that its activity is antagonized at iron concentrations above 10 microM. The iron-antagonized inhibitor was separated from the fluorescent siderophore of this pseudomonad by gel filtration. Mutants that lacked either the iron-antagonized inhibitor or the fluorescent siderophore were isolated. Results of complementation analysis of these mutants by use of a cosmid library indicated that distinct DNA sequences are required for the production of each factor. Analysis of isogenic mutant strains showed that the genetic requirements for the production of the iron-antagonized inhibitor and the fluorescent siderophore are different, and that only the fluorescent siderophore is required for iron assimilation. Fusions of these same sequences to a beta-galactosidase gene were used to show that the regions required for the production of both the fluorescent siderophore and the iron-antagonized inhibitor were iron-regulated.
High-resolution holographic image projection at visible and ultraviolet wavelengths (1988)

Holograms of resolution test masks have been recorded in photoresist using visible and ultraviolet lasers. Reconstructed images have been projected onto and recorded in photoresist by lithography. Speckle-free submicron resolution has been achieved using simple and inexpensive optical systems and using lasers with limited coherence. Using these techniques with excimer lasers single-shot recording with exposure time of ~20 ns and multishot reconstruction with exposure time </= 1 s are possible for image fields up to 10 cm in diameter.
Line codes and repeater fault location schemes for optical transmission systems (1982)

Abstract In this report, the line code structures of optical transmission systems are compared from the viewpoint of providing bit sequence independence (BSI). Repeater fault location schemes are also studied. Initially, we shall describe what considerations should be made to avoid consecutive identical codes as well as pseudo‐synchronism in accordance with the inherent meaning of BSI, and we shall show a specialized code pattern to be considered for protecting pseudo‐synchronism and a frame format to avoid pseudo‐synchronism. Furthermore, we shall show the repeater fault location schemes for the phase‐difference‐detection type of CMI code transmission system and the m BIP code transmission system with odd parity, and we shall indicate how simple they are to realize. Then the transmission line code schemes of the 100 Mb/s optical cable transmission system are compared, and it is concluded that the preferable frame format is that in which frame synchronization pulses are inserted at positions different from the parity bits based on the 7 BIP code. In addition, experimental studies of the characteristics of the timing system in the repeater of the DF‐100M system [1] will indicate the appropriateness of the design jitters and the selection of the frame format of the repeater.
