Acquiring robot skills via reinforcement learning (1994)

Skill acquisition is a difficult , yet important problem in robot performance. The authors focus on two skills, namely robotic assembly and balancing and on two classic tasks to develop these skills via learning: the peg-in hole insertion task, and the ball balancing task. A stochastic real-valued (SRV) reinforcement learning algorithm is described and used for learning control and the authors show how it can be used with nonlinear multilayer ANNs. In the peg-in-hole insertion task the SRV network successfully learns to insert to insert a peg into a hole with extremely low clearance, in spite of high sensor noise. In the ball balancing task the SRV network successfully learns to balance the ball with minimal feedback.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Mycoflora and Ochratoxin A Control in Wheat Grain Using Natural Extracts Obtained from Wine Industry By-Products (2012)

The aim of this study was to evaluate the effect of some natural extracts obtained from grape pomace (GPE) and grape seeds (GSE) as compared to a synthetic food, antioxidant-butylated hydroxytoluene (BHT), in order to control fungal population and ochratoxin A (OTA) production in naturally contaminated wheat. The results showed that the addition of these extracts was efficient with OTA content decreasing. On treatment with these extracts the loss of OTA content after 14 days was in the range 7.8-28.3% relative to the control sample, but increased up to 26.48-37% after 28 days. The highest loss in OTA content was recorded for treatment with GPE at the 500 ppm level. Regarding the fungal development, the obtained results show that the total fungal populations were significantly reduced by using natural extracts. The most efficient extract was GPE. Both BHT and GPE inhibit the growth of Penicillium verrrucosum, for all doses, but less with Aspergillus genera. GPE affects the growth of other types of moulds such as Rhizopus microsporus, Fusarium graminearum, Alternaria infectoria and Cladosporium herbarum. Our data suggested that GPE and GSE are able to provide fungicidal and fungistatic protection and to control the OTA accumulation in wheat, at least in a similar manner to BHT.
Revision, extension, and evaluation of a binaural speech intelligibility model (2010)

This study presents revision, extension, and evaluation of a binaural speech intelligibility model (Beutelmann, R., and Brand, T. (2006). J. Acoust. Soc. Am. 120, 331-342) that yields accurate predictions of speech reception thresholds (SRTs) in the presence of a stationary noise source at arbitrary azimuths and in different rooms. The modified model is based on an analytical expression of binaural unmasking for arbitrary input signals and is computationally more efficient, while maintaining the prediction quality of the original model. An extension for nonstationary interferers was realized by applying the model to short time frames of the input signals and averaging over the predicted SRT results. Binaural SRTs from 8 normal-hearing and 12 hearing-impaired subjects, incorporating all combinations of four rooms, three source setups, and three noise types were measured and compared to the model's predictions. Depending on the noise type, the parametric correlation coefficients between observed and predicted SRTs were 0.80-0.93 for normal-hearing subjects and 0.59-0.80 for hearing-impaired subjects. The mean absolute prediction error was 3 dB for the mean normal-hearing data and 4 dB for the individual hearing-impaired data. 70% of the variance of the SRTs of hearing-impaired subjects could be explained by the model, which is based only on the audiogram.

Behavioral biometrics for persistent single sign-on (2011)

Driven by the rapid development of ubiquitous and pervasive computing, personalized services and applications are deployed to support our lives. Accordingly, the number of interfaces and devices (smartphone, tablet computer, etc.) provided to access and consume these services is growing continuously. To simplify the complexity of managing many accounts with different credentials, Single Sign-On (SSO) solutions have been introduced. However, a single password for many accounts represents a single-point-of-failure. Furthermore, once initiated SSO session is a high potential risk when the working station is left unlocked and unattended. In this paper, we present a conception of a Persistent Single Sign-On (PSSO) for ubiquitous home environments by involving the capabilities of Behavioral Biometrics to check the identity of the user continuously in an unobtrusive manner.

A CMOS 40 MHz 8 b 105 mW two-step ADC (2003)

To meet the demand for digital signal processing of wideband video signals, a 40-MHz, 8-b ADC (analog/digital converter) with 105-mW power consumption on a 4.88-mm/sup 2/ chip has been developed using a 1.4- mu m standard-cell CMOS process. To obtain 8-b fast conversion, the ADC uses a sample-and-hold comparator with an averaging feature for differential linearity for high-speed sampling and high-frequency inputs and an expanded fine comparison to increase conversion speed. The block diagram of the converter is shown together with two techniques employed to increase conversion speed. The DC linearity of the converter at a 40-MHz conversion rate is shown. The limit of differential linearity is less than +or-0.5 least significant bit for 8 b. The measured power consumption as a function of sampling frequency and supply voltage is also shown. For 40-MHz sampled at a supply voltage of 5 V, the power consumed is 105 mW. For 14.3-MHz sampling at 3.5 V, the consumption drop to 27 mW.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Aircraft dynamic navigation for unmanned aerial vehicles (2014)

This thesis describes the investigation of an Aircraft Dynamic Navigation (ADN) approach, which incorporates an Aircraft Dynamic Model (ADM) directly into the navigation filter of a fixed-wing aircraft or UAV. The result is a novel approach that offers both performance improvements and increased reliability during short-term GPS outages. This is important in allowing future UAVs to achieve routine, unconstrained, and safe operations in commercial environments. The primary contribution of this research is the formulation Unscented Kalman Filter (UKF) which incorporates a complex, non-linear, laterally and longitudinally coupled, ADM, and sensor suite consisting of a Global Positioning System (GPS) receiver, Inertial Measurement Unit (IMU), Electronic Compass (EC), and Air Data (AD) Pitot Static System.
Energy Source Aware Target Cell Selection and Coverage Optimization for Power Saving in Cellular Networks (2010)

The spread of mobile connectivity is generating major social and economic benefits around the world, while along with the rapid growth of new telecommunication technologies like mobile broadband communication and M2M (Machine-to-Machine) networks, larger number of various base stations will be employed into the network, which will greatly increase the power expense and CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> emission. In order to degrade the system power expense, variety of researches on new energy and novel transmission technology are put in agenda. In this paper, instead of reducing the absolute power expense, the research focuses on guiding more power consumption into green source energy, which implying that the UEs (User Equipment), especially the cell edge UEs, will have preferential access to the BSs (Base Station) with natural energy supply. To realize the tendentious connection, two detailed approaches are proposed, the HO (Hand Over) parameter tuning for target cell selection and power control for coverage optimization. The system evaluation shows that, by proper setting of parameters in HO and power control, both of the two approaches can achieve good balance between energy saving effect and system throughput impact.
TRPM8 in the negative regulation of TNFα expression during cold stress (2017)

Transient Receptor Potential Melastatin-8 (TRPM8) reportedly plays a fundamental role in a variety of processes including cold sensation, thermoregulation, pain transduction and tumorigenesis. However, the role of TRPM8 in inflammation under cold conditions is not well known. Since cooling allows the convergence of primary injury and injury-induced inflammation, we hypothesized that the mechanism of the protective effects of cooling might be related to TRPM8. We therefore investigated the involvement of TRPM8 activation in the regulation of inflammatory cytokines. The results showed that TRPM8 expression in the mouse hypothalamus was upregulated when the ambient temperature decreased; simultaneously, tumor necrosis factor-alpha (TNFα) was downregulated. The inhibitory effect of TRPM8 on TNFα was mediated by nuclear factor kappa B (NFκB). Specifically, cold stress stimulated the expression of TRPM8, which promoted the interaction of TRPM8 and NFκB, thereby suppressing NFκB nuclear localization. This suppression consequently led to the inhibition of TNFα gene transcription. The present data suggest a possible theoretical foundation for the anti-inflammatory role of TRPM8 activation, providing an experimental basis that could contribute to the advancement of cooling therapy for trauma patients.
Causal association of electromagnetic signals using the Cayley–Menger determinant (2009)

In complex electromagnetic environments it can often be difficult to determine whether signals received by an antenna array emanated from the same source. The failure to appropriately assign signal reception events to the correct emission event makes accurate localization of the signal source impossible. In this paper we show that as the received signal events must lie on the light-cone of the emission event the Cayley–Menger determinate calculated from using the light-cone geodesic distances between received signals must be zero. This result enables us to construct an algorithm for sorting received signals into groups corresponding to the same far-field emission.
Attenuated Inflammatory Response in Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) Knock-Out Mice following Stroke (2013)

Although we initially expected an exaggerated pro-inflammatory response following ablation of TREM2, our data support a contradictory scenario that the sub-acute inflammatory reaction after stroke is attenuated in TREM2-KO mice. We therefore conclude that TREM2 appears to sustain a distinct inflammatory response after stroke.
Milton's God: Authority in “Paradise Lost” (1972)

ABSTRACT Milton's God consistently evokes an unfavorable reaction in the modern reader, the result not so much of our emotional response to Christianity as of our antipathy to absolute authority. This response is ironic because Milton too opposed authority, but only usurped human authority, since from the perspective of Adam all men are brothers. Paradise Lost presents, in contrast to the abuse of authority in the world, a vision of God's ideal justice, corresponding to the vision of bliss in Eden. The manner of Milton's God has offended, but he speaks as he must: with absolute certitude, with spareness and logic, without recourse to metaphor or sensuous appeal. Nevertheless, his speeches are transcendentally poetic. The Father has been accused of lacking love, but the love which the Son embodies originates with the Father, and is the necessary basis in Paradise Lost for just power. Although the Father reveals little directly of what he is, he is defined by his Son and by his creatures: man, the animals, the physical universe. The human love of Adam and Eve, apparently in contention with divine love, actually depends on it for its existence. So the Father is defined by everything he creates; and what he creates is beautiful and good.
Biased Bilayer Graphene: Semiconductor with a Gap Tunable by the Electric Field Effect (2007)

We demonstrate that the electronic gap of a graphene bilayer can be controlled externally by applying a gate bias. From the magnetotransport data (Shubnikov-de Haas measurements of the cyclotron mass), and using a tight-binding model, we extract the value of the gap as a function of the electronic density. We show that the gap can be changed from zero to midinfrared energies by using fields of less, approximately < 1 V/nm, below the electric breakdown of SiO2. The opening of a gap is clearly seen in the quantum Hall regime.
Rhizobium meliloti genes involved in sulfate activation: the two copies of nodPQ and a new locus, saa. (1992)

The nitrogen-fixing symbiont Rhizobium meliloti establishes nodules on leguminous host plants. Nodulation (nod) genes used for this process are located in a cluster on the pSym-a megaplasmid of R. meliloti. These genes include nodP and nodQ (here termed nodPQ), which encode ATP sulfurylase and APS kinase, enzymes that catalyze the conversion of ATP and SO(4)2- into the activated sulfate form 3'-phosphoadenosine 5'-phosphosulfate (PAPS), an intermediate in cysteine synthesis. In Rhizobium, PAPS is also a precursor for sulfated and N-acylated oligosaccharide Nod-factor signals that cause symbiotic responses on specific host plants such as alfalfa. We previously found a highly conserved second copy of nodPQ in R. meliloti. We report here the mapping and cloning of this second copy, and its location on the second megaplasmid, pSym-b. The function of nodP2Q2 is equivalent to that of nodP1Q1 in complementation tests of R. meliloti and Escherichia coli mutants in ATP sulfurylase and adenosine 5'-phosphosulfate (APS) kinase. Mutations in nodP2Q2 do not have as severe an effect on symbiosis or plant host range as do those in nodP1Q1, however, possibly reflecting differences in expression and/or channeling of metabolites to specific enzymes involved in sulfate transfer. Strains mutated or deleted for both copies of nodQ are severely defective in symbiotic phenotypes, but remain prototrophic. This suggests the existence in R. meliloti of a third locus for ATP sulfurylase and APS kinase activities. We have found a new locus saa (sulfur amino acid), which may also encode these activities.
Using UAV for unmanned agricultural harvesting equipment route planning and harvest volume measuring (2017)

The method of unmanned harvesting equipment route planning with the use of unmanned aerial vehicle is proposed. The problem of harvest volume measuring is solved on the basis of statistical processing of digital image spectral characteristics for each region with the use of neural networks.
Electromagnetic ground-wave field of vertical antennas for communication at 1 to 30 MHz (1998)

Radio communication over the spherical surface of the Earth and sea makes use of vertical antennas in the frequency range from 1 to 30 MHz. For distances that extend beyond the approximation of a planar Earth, use must be made of the ground-wave. Following a description of antennas used on shipboard, their radiated fields are analyzed in the planar- and spherical-Earth regions. The latter involves new formulas for the field of vertical dipoles over the spherical surface of the sea.
Stress control of polycrystalline 3C-SiC films in a large-scale LPCVD reactor using 1,3-disilabutane and dichlorosilane as precursors (2006)

Control of residual stress and strain gradient of polycrystalline SiC films deposited via low-pressure chemical vapor deposition on 100 mm Si wafers is achieved by varying dichlorosilane (DCS) and 1,3-disilabutane (DSB) fractions in the inlet gas mixture. For films deposited at 800 °C and 45 sccm DSB, stress decreases from 1.2 GPa tensile with no added DCS to 240 MPa tensile with 40 sccm DCS added to the inlet gas stream. The lowest magnitude strain gradient achieved is 3.1 × 10−5 µm−1 with 20 sccm DCS added. Electron probe microanalysis indicates that the films change from being slightly carbon-rich in the absence of DCS to successively more silicon-rich with the addition of DCS.
Mutation of Arginine 44 of GAT-1, a (Na+ + Cl−)-coupled γ-Aminobutyric Acid Transporter from Rat Brain, Impairs Net Flux but Not Exchange (2000)

The gamma-aminobutyric acid (GABA) transporter GAT-1 is a prototype of a large family of neurotransmitter transporters that includes those of dopamine and serotonin. GAT-1 maintains low synaptic concentrations of neurotransmitter by coupling GABA uptake to the fluxes of sodium and chloride. Here we identify a stretch of four amino acid residues predicted to lie in the juxtamembrane region prior to transmembrane domain 1 in the cytoplasmic amino-terminal tail of GAT-1, which is critical for its function. Two residues, arginine 44 and tryptophan 47, are fully conserved within the transporter family, and their deletion abolishes GABA transport in the HeLa cell expression system used. Tryptophan 47 can be replaced only by aromatic residues without loss of activity. Arginine 44 is essential for activity. Only when it is replaced by lysine, low activity levels (around 15% of those of the wild type) are observed. Using a reconstitution assay, we show that mutants in which this residue is replaced by lysine or histidine exhibit sodium- and chloride-dependent GABA exchange similar to the wild type. This indicates that these mutants are selectively impaired in the reorientation of the unloaded transporter, a step in the translocation cycle by which net flux and exchange differ. The high degree of conservation in the consensus sequence RXXW suggests that this region may influence the reorientation step in related transporters as well.
