Algorithms on dynamic priority scheduling for heterogeneous traffic in ATM (2002)

Double minimum laxity threshold (MLT), double queue length threshold (QLT), and hysteresis QLT algorithms are proposed as dynamic priority scheduling techniques for advanced processing of multiple class traffic. The performance of the proposed algorithm is analyzed by computer simulation. According to the simulation results, it can be shown that the proposed algorithms enhance the processing performance versus the conventional algorithm for two or more classes of delay sensitive traffic and for two or more classes of non-real-time traffic.
Nonuniformity correction algorithm based on Gaussian mixture model (2011)

As an important tool to acquire information of target scene, infrared detector is widely used in imaging guidance field. Because of the limit of material and technique, the performance of infrared imaging system is known to be strongly affected by the spatial nonuniformity in the photoresponse of the detectors in the array. Temporal highpass filter(THPF) is a popular adaptive NUC algorithm because of its simpleness and effectiveness. However, there still exists the problem of ghosting artifact in the algorithms caused by blind update of parameters, and the performance is noticeably degraded when the methods are applied over scenes with lack of motion. In order to tackle with this problem, a novel adaptive NUC algorithm based on Gaussian mixed model (GMM) is put forward according to traditional THPF. The drift of the detectors is assumed to obey a single Gaussian distribution, and the update of the parameters is selectively performed based on the scene. GMM is applied in the new algorithm for background modeling, in which the background is updated selectively so as to avoid the influence of the foreground target on the update of the background, thus eliminating the ghosting artifact. The performance of the proposed algorithm is evaluated with infrared image sequences with simulated and real fixed-pattern noise. The results show a more reliable fixed-pattern noise reduction, tracking the parameter drift, and presenting a good adaptability to scene changes.
Traction force of smooth muscle cell during growth on a rigid substrate (2014)

This paper reports on the sensor for traction force measurement of a smooth muscle cell during cell growth on a rigid substrate, specially designed for horizontal and vertical directional forces. For quantitative measurement, the cells are cultured only on the sensor pads using a cover chip. The length of the sensor is 1130μm. The size of the sensor pad is 125μm×15μm×5μm (length×width× thickness). The gaps between the sensor pads are 3μm. We confirmed that the cells spread on the two sensor pads at least. We measured the traction forces of bovine aortic smooth muscle cells (BAOSMCs, CAB35405) using the proposed sensor. When the three cells spread on the pads, the measured traction forces in x and z direction increased 30nN and 20nN for 8 min, respectively.
Developing interactive information systems with the User Software Engineering methodology (1986)

User software engineering (USE) is a methodology, supported by automated tools, for the systematic development of interactive information systems. The USE methodology gives particular attention to effective user involvement in the early stages of the software development process, concentrating on external design and the use of rapidly created and modified prototypes of the user interface. The USE methodology is supported by an integrated set of graphically based tools. The USE methodology and the tools that support it are described.
Synthetic Multimeric Heptyl Mannosides as Potent Antiadhesives of Uropathogenic <i>Escherichia coli</i> (2009)

Urinary tract infections caused by uropathogenic Escherichia coli presents a serious communal and nosocomial health problem initiated by bacterial adhesion to the bladder cells. E. coli expresses fimbriae with a mannose-binding adhesin, FimH, at the tip. Heptyl alpha-D-mannoside (HM) is a nanomolar inhibitor of this lectin, preventing adhesion of type 1-piliated E. coli and reducing bacteria levels in a murine cystitis model. Herein, we described the synthesis of multimeric heptyl-mannosides with valencies ranging from one to four by copper-catalyzed azide alkyne cycloaddition (CuAAC). Biological evaluation of the multivalent compounds revealed an increase in potency compared to HM. Inhibition of bladder cell binding highlighted a promising tetravalent derivative with inhibitory concentrations 6000- and 64-fold lower than mannose and HM respectively.

Room localization for distant speech recognition (2014)

The problem of room localization is to determine where, in a multi-room environment, a person is producing a speech utterance.In our work, we are exploiting the information gained from a network of microphones installed all over a house, where the lack of calibration of the microphone energies creates an additional challenge.This paper compares room localizers based on different features (such as energy and cross-correlation between microphones) and classifiers (such as neural networks and discriminative analysis).In order to evaluate the different room localizers in terms of word accuracy this paper also presents a complete distant speech recognition system which tries to take advantage of synergy between the different components without using any oracle information.Finally, the system is analyzed in terms of computational and time resources.
Studies on the antinociceptive effects of sodium nitroprusside and molsidomine in mice. (1998)

The participation of nitric oxide (NO) in antinociceptive activity of molsidomine and sodium nitroprusside (SNP) was studied in mice using the writhing test. Molsidomine (300 and 150 mg/kg) and SNP (1.52-0.38 mg/kg) induced antinociception that was antagonized by naloxone. L-arginine (500-62.5 mg/kg) did not produce antinociceptive effects, whereas N omega-nitro-L-arginine methyl ester (L-NAME) (37.5-150 mg/kg) induced antinociception which was suppressed by naloxone. Methylene blue did not change the molsidomine- and SNP-induced antinociception, but significantly intensified that produced by L-NAME. L-arginine increased antinociceptive effect of molsidomine but not that of SNP. Antinociceptive activity of L-NAME was partially reversed by L-arginine. D-arginine failed to influence these effects. The present findings suggest that the NO-cGMP pathway is not involved in the mechanism of molsidomine- and SNP-induced antinociception in the writhing test in mice.
Application of a Molecularly Imprinted Polymer for the Extraction of Kukoamine A from Potato Peels (2011)

A molecularly imprinted polymer (MIP) for the purification of N(1),N(12)-bis(dihydrocaffeoyl)spermine (kukoamine A) was computationally designed and tested. The properties of the polymer were characterized. The protocol of the solid phase extraction (SPE) of kukoamine A from potato peels was optimized. A HPLC-MS method for the quantification of kukoamine A was developed and used for all optimization studies. The capacity of the MIP in relation to kukoamine A from the potato peels extract was estimated at 54 mg/g of the polymer. The kukoamine A purified from potato extract using MIP was exceptionally pure (≈ 90%). Although the corresponding blank polymer was less selective than the MIP for the extraction of kukoamine A from the potato extract, it was shown that the blank polymer could be effectively used for the purification of the crude synthetic kukoamine (polymer capacity = 80 mg of kukoamine A/g of the adsorbent, kukoamine A purity ≈ 86%). Therefore, selective adsorbents could be computationally designed for other plant products, allowing their purification in quantities that would be sufficient for more detailed studies and potential practical applications.
Glare suppression by coherence gated negation (2016)

Imaging of a weak target hidden behind a scattering medium can be significantly confounded by glare. We report a method, termed coherence gated negation (CGN), that uses destructive optical interference to suppress glare and allow improved imaging of a weak target. As a demonstration, we show that by permuting through a set range of amplitude and phase values for a reference beam interfering with the optical field from the glare and target reflection, we can suppress glare by an order of magnitude, even when the optical wavefront is highly disordered. This strategy significantly departs from conventional coherence gating methods in that CGN actively 'gates out' the unwanted optical contributions while conventional methods 'gate in' the target optical signal. We further show that the CGN method can outperform conventional coherence gating image quality in certain scenarios by more effectively rejecting unwanted optical contributions.
<title>Review of active methods for acoustic echo cancellation</title> (1993)

One of the technical goals in underwater acoustics is to design coatings to reduce the acoustic echo from submerged structures to avoid detection versus active sonar systems. At sufficiently high frequencies, this can be done using passive materials. At low frequencies, however, the task is more difficult, and active systems are under consideration. The purpose of this paper is to summarize the different principles of acoustic active control that can be considered and to point out advantages and difficulties, with a few examples. They include: (1) piezoelectric (pseudo-passive) coatings; (2) control of the impedance of a piezoelectric transducer; (3) distributed array of local sensor/actuator systems; (4) combined sensor and actuator arrays.
Sugar and Heavy Atom Effects of Glycoconjugated Chlorin Palladium Complex on Photocytotoxicity (2012)

Palladium(II) complexes of glycoconjugated porphyrin and pyrrolidine-fused chlorin were prepared to examine sugar and heavy atom effects on in vitro photocytotoxicity. Cellular uptake into HeLa cells was enhanced by introducing sugar units regardless of other features, such as the central ion (free base or palladium(II) ion) and the ring structure (porphyrin or chlorin). The palladium(II) complex of glycoconjugated pyrrolidine-fused chlorin (PdPC2) exerted an excellent degree of photocytotoxicity not only on HeLa cells, but also on metastatic B16-BL6 cells, weakly metastatic B16F1 cells, and metastatic 4T1 cells. However, free-base glycoconjugated pyrrolidine-fused chlorin (PC2) also exerted similar or much higher photocytotoxicity rather than PdPC2. Therefore, the palladium(II) ion did not improve the in vitro photocytotoxicity of PC2. The enhanced singlet oxygen generation of palladium(II) complexes (i.e., the heavy atom effect) was confirmed at least in O(2)-saturated D(2)O. In addition, the formation of hydrogen peroxide and hydroxyl radical were also detected in O(2)-saturated phosphate buffered saline. However, the reactive oxygen species (ROS) generation efficiency, which is the product of the (relative) quantum yield of each ROS and the light absorbing ability, did not fit the trends of photocytotoxicity seen for the photosensitizers. In our glycoconjugated photosensitizers tested, the best indicator of the photocytotoxicity was found to be the light absorbing ability (namely, the oscillator strength in the wavelength region applied in the photocytotoxicity test). These results indicated that photochemical characteristics of glycoconjugated photosensitizers were notably susceptible to the microenvironment. The biological characteristics, such as the sugar effect, were a much more reliable approach to improving the photocytotoxicity of photosensitizers.

Series-parallel generation of m-sequences (1975)

An equivalence class of machines is identified which generate maximal length sequences as a non-overlapping series of k-bit words. This is achieved at the expense of a k-fold increase in combinational logic but with no increase in the number of storage elements required.
Sealed-tube ignitron rectifiers (1942)

IN the past decade the advantages of the rectifier, when compared to other forms of conversion equipment, have led to the development of multianode steel tank and glass-bulb rectifiers. The desirable structural features and operating characteristics, however, have not been fully realized when pump-evacuated tanks and fragile glass-bulb rectifiers have been applied to small conversion units of low-voltage rating. Development of a means of starting or igniting <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> a cathode spot, each positive half cycle, on a pool of mercury has stimulated the design of a practicable half-wave or single-anode rectifier. The low density of ionization during the inverse cycle so reduced the shielding necessary to prevent arcback and, in consequence, the arc losses, that these rectifiers could be efficiently applied in the lower-voltage (250 volts d-c) fields.
Induction of micronucleus in NSC19 motoneuron cell line by genotoxic chemicals. (1997)

Micronucleus is formed when chromosomal fragments behave independently of remaining chromosomes during the division of cells damaged by genotoxic agents, and the frequency of micronucleus is considered to reflect genotoxic damage to cells. In order to obtain a simple, fas and low-cost assay system to evaluate genotoxicity in the nervous system, we utilize the micronucleus test in a NSC19 mouse neuroblastoma x spinal motoneuron hybrid cell line which was exposed to 4-nitroquinoline-N-oxide (4NQO). There was a significant increase in number of micronuclei in NSC19 cells following 24 hr exposure to 4NQO. Two other genotoxic chemicals, cytosine beta-D-arabinofuranoside (AraC) and ethylmethanesulfate (EMS), similarly increased the frequency of micronucleated cells in a dose-dependent manner. The micronucleus test described in the present study is useful as a short-term genotoxicity evaluation system for cells of nervous system origin.

A central thrust of these efforts exploits the synergistic relationship between SAR and MTI radar. Used together, they offer comprehensive coverage of the battlefield.
2D Nanoclay for Biomedical Applications: Regenerative Medicine, Therapeutic Delivery, and Additive Manufacturing (2019)

Clay nanomaterials are an emerging class of 2D biomaterials of interest due to their atomically thin layered structure, charged characteristics, and well-defined composition. Synthetic nanoclays are plate-like polyions composed of simple or complex salts of silicic acids with a heterogeneous charge distribution and patchy interactions. Due to their biocompatible characteristics, unique shape, high surface-to-volume ratio, and charge, nanoclays are investigated for various biomedical applications. Here, a critical overview of the physical, chemical, and physiological interactions of nanoclay with biological moieties, including cells, proteins, and polymers, is provided. The state-of-the-art biomedical applications of 2D nanoclay in regenerative medicine, therapeutic delivery, and additive manufacturing are reviewed. In addition, recent developments that are shaping this emerging field are discussed and promising new research directions for 2D nanoclay-based biomaterials are identified.
WHOLE BODY TRANSMISSION-EMISSION SCANNING WITH WHOLE BODY CAMERA (1975)

Whole body transmission-emission scanning was carried out using a whole body camera. A disk source 30 cm in diameter filled with 99mTc was used for transmission scanning. Correct interpretation of emission scanning requires accurate anatomical orientation of the images. The value of whole body transmission-emission scanning is emphasized.
Experiments in the Contextual Recognition of Cursive Script (1975)

In this paper a structure for a contextual cursive script recognition system is presented. This system makes use of letter context to determine word length, letter segmentation, and character identity to achieve contextual recognition at the word level. The system consists of a character recognizer that presents a set of best alternatives for each character to a contextual postprocessor whose task it is to determine the correct word.
Reactivity of nitric oxide with nickel ions in A-type zeolite (1980)

Nitric oxide adsorption over nickel-exchanged A-type zeolites has been investigated by gravimetry, e.s.r. and i.r. spectroscopy. Depending upon the nickel content of the zeolite and its dehydration process, four different nickel—nitrosyl complexes have been observed. They differ in structure as well as stability. Spin concentrations and gravimetric measurements agree well with an overall stoichiometry of one NO molecule per nickel ion in all cases.In zeolites containing less than one nickel ion per unit cell, two isolated Ni+—NO+ complexes have been detected by e.s.r. The nickel is tetrahedrally coordinated. These species are stable as the gas-phase NO is removed and show an i.r. absorption at 1876 cm–1.As nickel loading reaches two ions per unit cell, binuclear nickel—nitrosyl complexes are formed in the sodalite units. A bent (Ni+—NO+)2 complex with a central NO is detected on fully dehydrated zeolites (giso= 2.26; vNO= 1876–1882 cm–1). A different binuclear species (giso= 2.30) appears on zeolites which have been dehydrated in a gas flow; this unstable complex is though to have a (Ni+—NO+)2O structure, involving a bridging extra-framework oxygen. E.s.r. intensities give the relative proportions of the various species.
Turbo MAP decoder design for IS-2000 system (2002)

In the IMT-2000 specifications, the turbo code can be used for one of the channel coding methods. Especially in the data transmission requiring high data rates, this scheme can be adopted. We design a turbo MAP decoder for IS-2000 which is one of the IMT-2000 specifications. Design parameters and structures are generated by various simulation results. A modified window framing method is adopted and the log-MAP algorithm is replaced with MAX log-MAP algorithm. This hardware can decode for every data rates specified in IS-2000.
