Predicate projection in a bimodal spatial reasoning system (2007)

Spatial reasoning is a fundamental aspect of intelligent behavior, which cognitive architectures must address in a problem-independent way. Bimodal systems, employing both qualitative and quantitative representations of spatial information, are efficient and psychologically plausible means for spatial reasoning. Any such system must employ a translation from the qualitative level to the quantitative, where new objects (images) are created through the process of predicate projection. This translation has received little scrutiny. We examine this issue in the context of a bimodal spatial reasoning system integrated with a cognitive architecture (Soar). As part of this system, we define an expressive language for predicate projection that supports general and flexible image creation. We demonstrate this system on multiple spatial reasoning problems in the ORTS real-time strategy game environment.
LED lighting flicker and potential health concerns: IEEE standard PAR1789 update (2010)

The IEEE Standards Working Group, IEEE PAR1789 “Recommending practices for modulating current in High Brightness LEDs for mitigating health risks to viewers” has been formed to advise the lighting industry, ANSI/NEMA, IEC, EnergyStar and other standards groups about the emerging concern of flicker in LED lighting. This paper introduces power electronic designers for LED lighting to health concerns relating to flicker, demonstrates that existing technologies in LED lighting sometimes provide flicker at frequencies that may induce biological human response, and discusses a few methods to consider when trying to mitigate unintentional biological effects of LED lighting. The paper represents on-going work in IEEE PAR1789 that is vital to designing safe LED lamp drivers.
Effect of Upstream Reading Frames on Translation Efficiency in Simian Virus 40 Recombinants (1986)

In a previous report (S. Subramani, R. Mulligan, and P. Berg, Mol. Cell. Biol. 1:854-864, 1981), it was shown that mouse dihydrofolate reductase (DHFR) could be efficiently expressed from simian virus 40 recombinant viruses containing the DHFR cDNA in different locations in the viral late region. This was true even in the case of the SVGT7dhfr26 recombinant, which had the DHFR coding sequence 700 to 800 nucleotides from the 5' end of the mRNA, where it was preceded by the VP2 and VP3 initiator AUGs and a number of other noninitiator AUGs. To investigate the process of internal translation initiation in mammalian cells, we constructed a series of SVGT7dhfr recombinants in which the upstream VP2 and VP3 reading frame was terminated in various positions relative to the DHFR initiation codon. The efficient production of DHFR in infected CV1 cells depended on having the terminators of the VP2-VP3 reading frame positioned upstream or nearby downstream from the DHFR initiation codon. These results reinforce the notion that mammalian ribosomes are capable of translational reinitiation.
The AP-1 binding site in the feline immunodeficiency virus long terminal repeat is not required for virus replication in feline T lymphocytes (1993)

Sequences of 31 bp containing putative AP-1 and AP-4 binding sequences in the U3 region of the feline immunodeficiency virus (FIV) long terminal repeat (LTR) were deleted and the basal promoter activity of the LTR was measured by the chloramphenicol acetyltransferase (CAT) assay. The activity of the FIV LTR was reduced in Felis catus whole foetus 4 (fcwf-4) cells and Crandell feline kidney cells by this deletion. Cotransfection of murine c-Fos or c-Jun expression plasmids with the FIV LTR-CAT reporter plasmid into fcwf-4 cells revealed that FIV LTR could be activated by c-Fos but not c-Jun in the cells. The mutated LTR was introduced into an infectious molecular clone of FIV and the replication rate and the cytopathogenic activity of the mutant were compared with those of the wild-type in two feline CD4-positive T lymphoblastoid cell lines. It was found that the rate and activity of the mutant were almost the same as those of the wild-type. From these data, we conclude that the 31 bp fragment is important for achieving maximal expression of the FIV genome, but not required for the replication of FIV in feline T lymphocytes.

The new method described is useful for the screening of cereals in industrial quality control.
MIXOTROPHIC GROWTH MODIFIES THE RESPONSE OF <i>SPIRULINA (ARTHROSPIRA) PLATENSIS</i> (CYANOBACTERIA) CELLS TO LIGHT (2000)

Spirulina (Arthrospira) platensis (Nordstedt) Geitler cells grown under mixotrophic conditions exhibit a modified response to light. The maximal photosynthetic rate and the light saturation value of mixotrophic cultures were higher than those of the photoautotrophic cultures. Dark respiration and light compensation point were also significantly higher in the mixotrophically grown cells. As expected, the mixotrophic cultures grew faster and achieved a higher biomass concentration than the photoautotrophic cultures. In contrast, the growth rate of the photoautotrophic cultures was more sensitive to light. The differences between the two cultures were also apparent in their responses to exposure to high photon flux density of 3000 μmol·m<sup>-</sup><sup>2</sup> ·s<sup>-</sup><sup>1</sup> . The light-dependent O<sub>2</sub> evolution rate and the maximal efficiency of photosystem II photochemistry declined more rapidly in photoautotrophically grown than in mixotrophically grown cells as a result of exposure to high photon flux density. Although both cultures recovered from the high photon flux density stress, the mixotrophic culture recovered faster and to a higher extent. Based on the above results, growth of S. platensis with a fixed carbon source has a significant effect on photosynthetic activity.
3D Printing of Liquid Crystal Elastomeric Actuators with Spatially Programed Nematic Order (2018)

Liquid crystal elastomers (LCEs) are soft materials capable of large, reversible shape changes, which may find potential application as artificial muscles, soft robots, and dynamic functional architectures. Here, the design and additive manufacturing of LCE actuators (LCEAs) with spatially programed nematic order that exhibit large, reversible, and repeatable contraction with high specific work capacity are reported. First, a photopolymerizable, solvent-free, main-chain LCE ink is created via aza-Michael addition with the appropriate viscoelastic properties for 3D printing. Next, high operating temperature direct ink writing of LCE inks is used to align their mesogen domains along the direction of the print path. To demonstrate the power of this additive manufacturing approach, shape-morphing LCEA architectures are fabricated, which undergo reversible planar-to-3D and 3D-to-3D' transformations on demand, that can lift significantly more weight than other LCEAs reported to date.
Properties of Al<i>x</i>Ga1−<i>x</i>N films prepared by reactive molecular beam epitaxy (1982)

Single-crystal films of the solid solution AlxGa1−xN of the entire composition range have been fabricated on sapphire and silicon substrates by reactive molecular beam epitaxy (MBE) at 700 °C. The properties of the films have been studied by the reflection high energy electron diffraction technique, x-ray diffraction, and electrical and optical measurements. The lattice constant of the film is not a linear function of the composition, and the fundamental absorption edge also shows nonlinear dependence on the composition. The narrow intense peak of the cathodoluminescence concerned with the band to band or shallow impurity band transition, varies from 3.4 to 6 eV with the composition, which suggests the feasibility of AlxGa1−xN films grown by reactive MBE for optical devices in the ultraviolet spectral region.
Penalty-free, 100 Gbit/s optical transmission of< 2 pssupercontinuum transform-limited pulses over 40 km (1995)

100 Gbit/s, < 2 ps transform-limited supercontinuum optical pulses are transmitted for the first time at three wavelengths over 40 km with less than 1 dB power penalty, maintaining a small time-bandwidth product of less than 0.2. The new source can be applied to ultrafast TDM/WDM transmission and signal processing approaching 1 Tbit/s.
Fast and Incremental Method for Loop-Closure Detection Using Bags of Visual Words (2008)

In robotic applications of visual simultaneous localization and mapping techniques, loop-closure detection and global localization are two issues that require the capacity to recognize a previously visited place from current camera measurements. We present an online method that makes it possible to detect when an image comes from an already perceived scene using local shape and color information. Our approach extends the bag-of-words method used in image classification to incremental conditions and relies on Bayesian filtering to estimate loop-closure probability. We demonstrate the efficiency of our solution by real-time loop-closure detection under strong perceptual aliasing conditions in both indoor and outdoor image sequences taken with a handheld camera.
EtherIP: Tunneling Ethernet Frames in IP Datagrams (2002)

This document describes the EtherIP, an early tunneling protocol, to provide informational and historical context for the assignment of IP protocol 97. EtherIP tunnels Ethernet and IEEE 802.3 media access control frames in IP datagrams so that non-IP traffic can traverse an IP internet. The protocol is very lightweight, and it does not provide protection against infinite loops.
METALLURGICAL STABILITY OF SEVERAL BORIDE DISPERSION SYSTEMS (1960)

The metallurgical stability (compatibility) of 80 different boride-metal systems was determined experimentally. Specifically, the compatibility of some MB/sub 2/ borides (HfB/sub 2/, TiB/sub 2/, VB/sub 2/, ZrB/sub 2/), MB/sub 4/ borides (B/sub 4/C, YB/sub 4/), and MB/sub 6/ bo rides (CaB/sub 6/, EuB/sub 6/, SmB/sub 6/, and YB/sub 6/) with the metals Ti, Zr. Fe, stainless steel (304), Ni, Cu, Ag, and Al, respectively, was determined using the methods of x ray diffraction and metallography. Determinations were made on disperse powder samples at temperatures and times consistent with anticipated fabrication parameters. (auth)
X-ray absorption spectra of graphene from first-principles simulations (2010)

Near edge x-ray absorption fine-structure spectra of graphenes are calculated using hybrid density-functional theory with the equivalent core hole approximation, aiming to resolve the ongoing debate on the interpretation of corresponding experimental spectra. Effects of size, stacking, edges, and defects on the spectra have been analyzed in detail for both $\text{C}\text{ }1s\text{\ensuremath{-}}{\ensuremath{\pi}}^{\ensuremath{\ast}}$ and $\text{C}\text{ }1s\text{\ensuremath{-}}{\ensuremath{\sigma}}^{\ensuremath{\ast}}$ transitions. The infinite graphene sheet has been modeled by graphene nanoribbons of different size. The size dependence and convergence of the spectra have been revealed. It is found that the $\ensuremath{\pi}\text{\ensuremath{-}}\ensuremath{\pi}$ interaction between layers have mainly effects on the $\text{C}\text{ }1s\text{\ensuremath{-}}{\ensuremath{\pi}}^{\ensuremath{\ast}}$ transitions in two different energy regions. The stacking effect smears out the double-peaks structure of the first main ${\ensuremath{\pi}}^{\ensuremath{\ast}}$ peak around 285 eV and results in blueshift of the second ${\ensuremath{\pi}}^{\ensuremath{\ast}}$ structure by almost 2 eV. The calculations show that the $\ensuremath{\pi}$ spectrum of hydrogen saturated edge carbons is redshifted with respect to the central ones and that a new weak ${\ensuremath{\sigma}}^{\ensuremath{\ast}}$ peak around 288 eV appears. The presence of defects can also introduce new spectral features in both $\ensuremath{\pi}$ and $\ensuremath{\sigma}$ regions.
Aryl Thiol Substrate 3-Carboxy-4-Nitrobenzenethiol Strongly Stimulating Thiol Peroxidase Activity of Glutathione Peroxidase Mimic 2, 2'-Ditellurobis(2-Deoxy-β-Cyclodextrin) (2004)

Artificial glutathione peroxidase (GPx) model 2, 2'-ditellurobis(2-deoxy-beta-cyclodextrin) (2-TeCD) which has the desirable properties exhibited high substrate specificity and remarkably catalytic efficiency when 3-carboxy-4-nitrobenzenethiol (ArSH) was used as a preferential thiol substrate. The complexation of ArSH with beta-cyclodextrin was investigated through UV spectral titrations, fluorescence spectroscopy, 1H NMR and molecular simulation, and these results indicated that ArSH fits well to the size of the cavity of beta-cyclodextrin. Furthermore, 2-TeCD was found to catalyze the reduction of cumene peroxide (CuOOH) by ArSH 200,000-fold more efficiently than diphenyl diselenide (PhSeSePh). Its steady-state kinetics was studied and the second rate constant kmax/KArSH was found to be 1.05 x 10(7) M(-1) min(-1) and similar to that of natural GPx. Moreover, the kinetic data revealed that the catalytic efficiency of 2-TeCD depended strongly upon the competitive recognition of both substrates for 2-TeCD. The catalytic mechanism of 2-TeCD catalysis agreed well with a ping-pong mechanism, in analogy with natural GPx, and might exert its thiol peroxidase activity via tellurol, tellurenic acid, and tellurosulfide.
Trading-off among accuracy, similarity, diversity, and long-tail (2013)

Improving recommendation accuracy is the mostly focused target of recommendation systems, while it has been increasingly recognized that accuracy is not enough as the only quality criterion. More concepts have been proposed recently to augment the evaluation dimensions, such as similarity, diversity, long-tail, etc. Simultaneously considering multiple criteria leads to a multi-task recommendation. In this paper, a graph-based recommendation approach is proposed to effectively and flexibly trade-off among them.
WHAT SAFETY INITIATIVES HAVE BEEN INTRODUCED IN RESPONSE TO (2013)

With any new technology in aviation come new regulations, policies and concerns about safety related to the implementation of this new technology. The purpose of this research is to explain what aviation safety initiatives have been introduced in response to the use of glass cockpits in general aviation. The method that will be used to explore this topic and answer this question will be a literature review of already published information on glass cockpits. This information will be taken from aviation-related articles, reports, studies and websites. Discussion about policy changes that have been developed due to the introduction and continued use of glass cockpit technology will be explained, including studies completed by aviation organizations to compare this technology to conventional aviation cockpit panels and their results. Studies show that training is an important factor to this topic. Increased training means more time and more money will need to be put forth by those learning to fly and teaching to fly, as well as by those building and bettering aviation technologies, all in order to continue to make flight a possibility.
Chemical Nucleation for CVD Diamond Growth (2001)

A new nucleation method to form diamond by chemically pretreating silicon (111) surfaces is reported. The nucleation consists of binding covalently 2,2-divinyladamantane molecules on the silicon substrate. Then low-pressure diamond growth was performed for 2 h via microwave plasma CVD in a tubular deposition system. The resulting diamond layers presented a good cristallinity and the Raman spectra showed a single very sharp peak at 1331 cm(-1), indicating high-quality diamonds.

Cumulative Damage in Fretting Fatigue of Pinned Joints Subjected to Narrow Band Random Loading (1970)

Summary Fatigue tests have been made in constant amplitude loading and in narrow band random loading on FV520B steel lugs of width 27 mm loaded by means of a pin 12·7 mm in diameter. The test frequency was 220 Hz, a mean tensile stress of 309 N/mm 2 was used and tests extended for endurances of up to 10 9 cycles. For endurances up to 10 6 cycles there was good agreement between constant amplitude and random loading results with both stresses expressed in root mean square values. Beyond this endurance, the random loading results lay below those obtained in constant amplitude loading. Predictions made using the Palmgren-Miner cumulative damage hypothesis in conjunction with the endurance curve in constant amplitude loading gave good agreement with the results in random loading over the whole range of endurances tested.
The differential geometric modelling of compressor blades (2005)

Surface splining is used to obtain a differential geometric model for complicated smooth surfaces, e.g., refurbished compressor blades. Modifications to standard parametric splining techniques are introduced to improve the accuracy of the modelling scheme, to maintain stability, and to clear the way for real-time automation. The differential geometry underlying the model can be used to assist in deburring, surface finishing and tool-position control.
A survey of service discovery protocols for mobile ad hoc networks (2008)

With the enlargement of the network size and application scope of mobile ad hoc networks, the variety and number of service needed by such networks become more and more. Furthermore, in this dynamic environment, different nodes offering different services may enter and leave the network at any time. Efficient and timely service discovery becomes a new task of mobile ad hoc network. Discovery of services is a crucial feature for the usability of mobile ad hoc networks. In this paper, we survey the researches of recent years on service discovery, classify the existing service discovery protocols of mobile ad hoc networks. Moreover, we analyze and compare these protocols. Based on the analysis, further research issues that still need investigation are listed.
Split-Array, C-2C Switched-Capacitor Power Amplifiers (2018)

This paper presents a 13-b C-2C split-array (SA) multiphase switched-capacitor power amplifier (SAMP-SCPA) implemented in 65-nm CMOS. The SAMP-SCPA was designed for 16-b resolution to offer extra states for linearization/calibration using digital pre-distortion (DPD). Resolution limits for SA SCPAs are presented. The SAMP-SCPA allows for the improvement of the SCPA resolution while minimizing the impact on the input power required driving it. A prototype SAMP-SCPA, occupying 0.85 mm $\times $ 2 mm, delivers a peak output power of 24 dBm with a peak system efficiency (SE) of 40% at 1.8 GHz. When amplifying a long-term evolution (LTE) signal, the average output power and SE are 18.8 dBm and 21.6%, respectively, with an adjacent channel leakage ration (ACLR) <; -30 dBc and error vector magnitude (EVM) of 2.65% rms. The increased resolution allows output power to be traded off for improved linearity and a low power mode demonstrates an EVM as low as 1% rms.

Coatomer, the Coat Protein of COPI Transport Vesicles, Discriminates Endoplasmic Reticulum Residents from p24 Proteins (2006)

In the formation of COPI vesicles, interactions take place between the coat protein coatomer and membrane proteins: either cargo proteins for retrieval to the endoplasmic reticulum (ER) or proteins that cycle between the ER and the Golgi. While the binding sites on coatomer for ER residents have been characterized, how cycling proteins bind to the COPI coat is still not clear. In order to understand at a molecular level the mechanism of uptake of such proteins, we have investigated the binding to coatomer of p24 proteins as examples of cycling proteins as well as that of ER-resident cargos. The p24 proteins required dimerization to interact with coatomer at two independent binding sites in gamma-COP. In contrast, ER-resident cargos bind to coatomer as monomers and to sites other than gamma-COP. The COPI coat therefore discriminates between p24 proteins and ER-resident proteins by differential binding involving distinct subunits.

Photoreceptor Orientation (1981)

Retinal photoreceptor orientation was found to be disturbed in the region bordering an area of choroidal atrophy in the eye of a human observer. This disturbance was inferred from the locations of the peaks of psychophysical Stiles-Crawford functions. These peak locations progressively shifted from a normal location near the center of the pupil to well beyond the nasal pupillary margin as the retinal test location approached the visible lesion. We conclude that this disturbance of photoreceptor orientation reflects the operation of tractional forces that interfere with the reorientation of the receptors toward the pupil in a sizable area of the retina surrounding the traction-inducing lesion.
