Spectral and spatial decorrelation of Landsat-TM data for lossless compression (1995)

Presents some new techniques of spectral and spatial decorrelation in lossless data compression of remotely sensed imagery. These techniques provide methods to efficiently compute the optimal band combination and band ordering based on the statistical properties of Landsat-TM data. Experiments on several Landsat-TM images show that using both the spectral and the spatial nature of the remotely sensed data results in significant improvement over spatial decorrelation alone. These techniques result in higher compression ratios and are computationally inexpensive.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Bit-parallel wavelength links for high-performance computer networks (1996)

This paper describes a new interconnect and local area network transmission concept for computer communications based on spectrally encoding one or more computer words into a wavelength datagram. At physical and data link level, this system resembles an optical ribbon cable, except that all the bits pass on one fiber optic waveguide. At the network level, such fiber optic link segments can be interconnected all-optically using 2x2 optical switches into ShuffleNet or other architectures that permit a photonic packet to pass from source to destination without being incumbered with the extra delay and bandlimiting associated with electronic switching and regeneration. Unique properties of such a system include low latency (<10ns), very high bandwidth (<100Gbit/s per port), precise time alignment (<10ps) of the individual word bits over km distances, and dynamic scalability to support cluster computing and distributed supercomputing. Novel system elements disclosed in this paper include: (J) a bit parallel wavelength (BPW) fiber optic link that uniquely maintains wavelength channel time alignment, (2) an innovative parallel stepped wavelength optical transmitter that time synchronizes each laser diode element at its optical output, (3) a spectral encoder/decoder that adds fault tolerance and optical message addressing capability, and (4) a technique for transmitting and maintaining time aligned multi-X solitons as parallel bits through fiber media. Applications to teraflop high performance parallel computing and DoD input/output (I/O) bound applications are described.
Phosphorescent oxygen sensors utilizing sulfur–nitrogen–phosphorus polymer matrices (1996)

Luminescent sensors based on composites comprising transition metal complexes immobilized in polymer matrices have attracted attention as oxygen sensors for both biomedical and barometric applications. Typically, phosphorescent dyes are dispersed in a polymer matrix of high gas permeability are used. Here, S–N–P polymers are used as a novel matrix material allowing the sensitivity of the sensors to be controlled over a wide range.
Joining forces in solving large-scale quadratic assignment problems in parallel (2002)

Program libraries are one way to make the cooperation between specialists from various fields successful: the separation of application-specific knowledge from application independent tasks ensures portability, maintenance, extensibility, and flexibility. This paper demonstrates the success in combining problem-specific knowledge for the quadratic assignment problem (QAP) with the raw computing power offered by contemporary parallel hardware by using the library of parallel search algorithms ZRAM. The solutions of 10 previously unsolved large standard test-instances of the QAP are presented.
Revisiting accelerator-rich CMPs (2015)

Heterogeneous Chip Multiprocessors (CMP)s, which combine processor cores with specialized HW accelerators, are one main approach to high-performance low-power computing. While it is promising for few accelerators, the scalability is a major challenge with increasing number of accelerators. Resources including memory, communication fabric and processor turn into bottlenecks and result in accelerator under-utilization and cripple the performance.
Automatic correcting method of geometric distortion in meteorological satellite noaa image (1989)

Abstract Geometric distortions contained in images of the meteorological satellite NOAA have been corrected using the calculated orbit values alone. Since the calculated orbit values usually contain errors, their precise corrections have been carried out using many ground control points (GCPs). If a position in the NOAA‐image coordinate corresponding to a GCP is covered by clouds, however, the correction is carried out manually by choosing another position which is not covered by clouds, since the displacement of the position is not certain. If there are many positions to correct manually, however, the time of manual operations increases, in addition to the occurrence of different values in the displacement of the position. This paper proposes an automatic correcting method of the geometric distortion. The method employs the sequential similarity detection algorithm for template matching using coastal‐line data including GCPs. For this operation, the pyramid structure is efficiently employed to increase the processing speed. A success or failure of template matching is determined automatically by using a correlation coefficient. From this result, the affine transformation coefficient is calculated so that the geometric distortion is corrected automatically. Transformations between the map coordinates, the ground‐surface coordinates, and the NOAA‐image coordinates are carried out by using the four‐point interpolation method so that their processing time is shortened. The effectiveness of this method is demonstrated.
A GaAs power amplifier for 3.3 V CDMA/AMPS dual-mode cellular phones (1995)

For CDMA/AMPS dual-mode cellular phones, a power amplifier operating at 3.3 V has been developed for the first time. It consists of linear GaAs power MESFET's and an output matching circuit which reduces the second and the third harmonics. The amplifier shows an output power of 31.5 dBm and a power-added efficiency of 61% for the AMPS mode. The third-order intermodulation distortion and the fifth-order one are measured to be -32 dBc and -45 dBc at an output power of 26 dBm for the CDMA mode.

Administration of MDMA to ethanol-deprived rats increases ethanol operant self-administration and dopamine release during reinstatement (2009)

Recreational use of (±)-3,4-methylenedioxymethamphetamine (MDMA, ecstasy) is often associated with other drugs, among which ethanol (EtOH) is one of the most common. However, little is known about how neurochemical sensitization produced by MDMA can modulate EtOH abuse. In this study we used EtOH operant self-administration tasks to investigate the effect of several low doses (0.33, 1.0 and 3.0 mg/kg) of MDMA in Dark Agouti rats. Motor activity was recorded after each MDMA administration. Changes in extracellular dopamine in the nucleus accumbens following a single EtOH injection (1.5 g/kg i.p.) were measured using intracerebral microdialysis in vivo after 1 wk of abstinence from EtOH, in order to mimic the dopaminergic response associated with reinstatement into EtOH consumption. Animals exposed to higher doses of MDMA (1.0 and 3.0 mg/kg) showed significantly enhanced EtOH self-administration during reinstatement and an increased EtOH-induced dopamine efflux. MDMA treatment acutely elevated motor activity after each administration in a dose-dependent manner. These findings suggest that repeated administration of MDMA, a relatively common drug of abuse, even at low doses, can alter subsequent vulnerability to EtOH consumption.
Application of urea complexes in the purification of fatty acids, esters, and alcohols. III. Concentrates of natural linoleic and linolenic acids (1953)

Summary Concentrates of natural linoleic acid (linoleic acid content, 85–95%) have been prepared in 50–72% yields from corn oil fatty acids by preferential precipitation of the saturated and monounsaturated fatty acids at room temperature as their urea complexes. By a similar procedure, concentrates of natural linolenic acid (linolenic acid content, 87–89%) have been prepared in 55–61% yields from perilla oil fatty acids by preferential precipitation of the saturated, monounsaturated, and diunsaturated fatty acids. Although concentrates of natural linolenic acid containing only 66–70% linolenic acid were obtained from linseed oil fatty acids, yields were 87–90%. A levelling‐off effect has been observed in the use of the preferential precipitation technique in raising the purity of concentrates of linoleic and linolenic acid. This parallels the experience in the purification of these acids by low‐temperature crystallization.
Modeling an electro-photographic printer, part I: monochrome systems (2007)

This paper will outline a simplified model for the development of toner dots on a reflective support. Using this model and the interaction of light between the reflective support and the dot's microstructure, the physical, optical and total dot-gain will be calculated, along with the resulting tone scales, for a variety of digital halftone patterns. The resulting tone reproduction curves and dot-gain will be compared with the classical literature on dot-gain and tone reproduction curves, more modern approaches and experimental data from the literature. A comparison to a well-defined experimental system will be shown.
Effects of Exercise, Bedrest and Napping on Performance Decrement During 40 Hours (1976)

ABSTRACT Young male Naval volunteers were denied normal noclurnal sleep and maintained on a 60‐min lreatment‐160‐min testing schedule during 40 consecutive hrs. Ten subjects bicycled, 20 subjects controlled EEG activity during bedrest, and 10 subjects napped. Eight measures of addition, auditory vigilance, mood, and oral temperature were obtained. The Bedrest group showed significant impairment on all eight measures, and thus, gave no support to lite forced‐rest theory of sleep function. The Exercise group was worse than the Nap and Bedrest groups for all measures. In spite of fragmented, reduced sleep (about 3.7 hrs per 24 hrs), the Nap group had no impairment on six of the measures. The results suggest that exercise increases the impairment due to sleep loss, and naps reduce or remove this impairment. Bedrest is not a substitute for sleep.
Mass spectrometry-based analysis of glycoproteins and its clinical applications in cancer biomarker discovery (2014)

Glycosylation is one of the most important posttranslational modifications of proteins and plays essential roles in various biological processes. Aberration in the glycan moieties of glycoproteins is associated with many diseases. It is especially critical to develop the rapid and sensitive methods for analysis of aberrant glycoproteins associated with diseases. Mass spectrometry (MS) has become a powerful tool for glycoprotein analysis. Especially, tandem mass spectrometry can provide highly informative fragments for structural identification of glycoproteins. This review provides an overview of the development of MS technologies and their applications in identification of abnormal glycoproteins and glycans in human serum to screen cancer biomarkers in recent years.
ChemInform Abstract: Metallomacrocycles: Synthesis, X‐Ray Structure, Electrochemistry, and ESR Spectroscopy of Mononuclear and Heterodinuclear Complexes. (1989)

Abstract The Ba2+‐templated (1:1) macrocyclization of dialdehydes such as (I) and (II) with 1,2‐diamino‐2‐methylpropane and o‐phenylenediamine offers a convenient route to heterodiligating ligands with two very different cavities.
Electro‐optical effects of azo dye containing liquid crystalline copolymers (1984)

Abstract The synthesis and phase behaviour of azo dye containing liquid crystalline side group copolymers are described. These Copolymers show the same electro‐optical effects as low molar mass guest‐host systems. Their macroscopic oriented nematic structure can be frozen in below the glass transition temperature resulting in a polymer film with dichroic properties. The behaviour of the copolymers (phase behaviour, surface and electric field orientation) can be improved via mixtures with low molar mass liquid crystals.
The isolation and identification of a new mutagen from fried ground beef: 2-amino-l-methyl-6-phenylimidazo[4, 5-b]pyridine (PhIP) (1986)

A new mutagenic compound has been isolated from ground beef which was fried at 300 degrees C for 5.5 min on each side. The new mutagen was purified using an aqueous acid extraction, XAD-2 adsorption-solvent elution, a series of preparative and analytical h.p.l.c. purification steps, and monitored with the Ames/Salmonella assay. This study reveals a new mutagen member of the amino-imidazoazaarene class of aromatic amines, having a mol. w of 224, and a formula of C13H12N4 as determined by high-resolution mass spectrometry. N.m.r. spectrometry supports the structure, 2-amino-1-methyl-6-phenyl-imidazo[4,5-b]pyridine (PhIP), for the new mutagen. The 1-methyl and 3-methyl synthesized isomers of PhIP were compared to the purified mutagen. The two isomers had identical mass spectra to the purified compound, but only the 1-methyl isomer showed similar u.v. and n.m.r. spectra. The two synthetic isomers were separable by h.p.l.c. and the beef derived component co-eluted with the 1-methyl-PhIP isomer. PhIP has a specific activity in the Ames/Salmonella assay of 1950 revertants/microgram. Although it is not as mutagenic as other compounds isolated from fried beef (e.g. MeIQx, 58 000 revertants/microgram) it is the most abundant mutagenic compound by mass in fried beef. PhIP is present at approximately 15 p.p.b. of the original weight of uncooked beef (accounting for 75% of the mass of genotoxic material) and contributes 18% of the total mutagenicity of the fried beef.
Structure-based virtual screening protocols. (2001)

Virtual screening techniques continue to play an important role within the pharmaceutical industry lead discovery process. A core element of these technologies encompasses the ability to virtually screen compound databases in three-dimensional (3-D) target active sites (structure-based virtual screening (SVS)). Reviewed are the latest developments within SVS, with particular emphasis on new technology and validation experiments. Examples of successful SVS application are highlighted, together with studies illustrating current technology limitations. New methods for scoring ligand-protein binding interactions are discussed, including the latest developments in ligand interaction sampling technology.
Role of cyclooxygenase (COX) in modulating vascular smooth muscle cell (VSMC) proliferation (2002)

The aim of this study was to investigate the role of COX in modulating vsmc proliferation. Serum and tumor necrosis factor- (TNF) are known to increase COX expression and activity in vsmc. TNF [1nM]-mediated, COX-2-dependent, PGI 2 and TXA 2 production increased approximately 4.5-fold and 2-fold, respectively. Addition of serum (0-5%) increased vsmc proliferation in a dose-dependent manner; addition of 5% serum for 48hr increased cell number by 3-fold. TNF potentiated the response to 5% serum by 34%, an effect that also was confirmed by evaluating the changes in S and G2/M phases of the cell cycle using laser scanning cytometry. Exposure of vsmc to 5% serum for 20hr increased the percentage of cells in S and G2/M phases by 55%; TNF increased this response by an additional 50%. Treatment with NS-398 [1M], a selective COX-2 inhibitor, prevented progression of the cell cycle induced by 5% serum and TNF5% serum. The role of COX-2 was further investigated by increasing its expression and activity using NO-donors. Papanonoate (PN; 500M), an NO donor, unlike TNF, preferentially increased PGI 2 but not TXA 2 synthesis (control: 86 17, PN: 428 54 pg 6-ketoPGF1/g protein; p0.01, n3). Sodium nitroprusside (SNP; 50M), another NO-donor, increased PGI 2 synthesis, which was blocked by NS-398 (1M)(control: 16.691.08; SNP 50 M: 53.818.90, SNPNS-398: 18.754.17 pg/g protein; p0.01, n3). SNP as well as Detanonoate (DN; 1mM) increased COX-2 protein expression, without affecting COX-1 protein expression. However, treatment with these NO-donors decreased cell number, an effect prevented by NS-398. The data indicate that NO donors preferentially stimulate PGI 2 production by vsmc. TNF, on the other hand, stimulates both PGI 2 and TXA 2 synthesis. Thus, increased COX-2 activity can lead to an increased proliferative response of vsmc in the presence of co-mitogens; whereas in the absence of a mitogen, NO inhibits vsmc proliferation in a COX-2-dependent manner.

Fundamental structural-acoustic idealizations for structures with fuzzy internals (1993)

Fundamental issues relative to structural vibration and to scattering of sound from structures with imprecisely known internals are explored, with the master structure taken as a rectangular plate in a rigid baffle, which faces an unbounded fluid medium on the external side. On the internal side is a fuzzy structure, consisting of a random array of point-attached spring-mass systems. The theory predicts that the fuzzy internal structure can be approximated by a statistical average in which the only relevant property is a function m F (Ω) which gives a smoothed-out total mass, per unit plate area, of all those attached oscillators which have their natural frequencies less than a given value Ω. The theory also predicts that the exact value of the damping in the fuzzy structure is of little importance, because the structure, even in the limit of zero damping, actually absorbs energy with an apparent frequency-dependent damping constant proportional to dm F (ω)/dω incorporated into the dynamical description of the master structure. A small finite value of damping within the internals will cause little appreciable change to this limiting value.
Understanding charge traps for optimizing Si-passivated Ge nMOSFETs (2016)

For the first time, two different types of electron traps are clearly identified in Ge nFETs with Type-A controlled by the HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> layer thickness and Type-B by the Si growth induced Ge segregation. Only Type-B are responsible for mobility degradation and they do not saturate with stress time, while the opposite applies to Type A. A PBTI model is proposed and validated for the long term prediction.
Complement Preservation in Citrated Human Blood (1970)

Total hemolytic complement activity was measured periodically in citrated samples of whole human blood stored for three weeks under usual blood bank conditions. The loss of complement was gradual; an average of 97 per cent of the total activity remained after one week and 90 per cent after three weeks.
Identifying Obstructive Sleep Apnea in Patients Presenting for Laser‐Assisted Uvulopalatoplasty (1996)

The authors report on a series of 850 patients with snoring who were evaluated for laser-assisted uvulopalatoplasty (LAUP). Stepwise multivariate linear regression was employed to correlate patient symptoms and characteristics to the respiratory disturbance index (RDI). Body mass index, falling asleep while driving, snoring every night, and stopping breathing during sleep were found to correlate strongly with an increasing RDI (variance of 25%). Logistic multivariate linear regression analysis was used to predict the outcome of apnea (RDI>10). This model selected all of the above variables, as well as age, male sex, and the total number of symptoms, as being strong predictors of apnea. A receiver operating characteristic curve was used to describe the ability of this model to predict apnea. The authors conclude that otolaryngologists play an important role in the evaluation of OSAS, especially when a snoring patient may undergo LAUP, and they present an algorithm for the evaluation of such a patient. The authors believe that the clinical assessment, including a thorough history and a complete physical examination, remains extremely important in this evaluation. At present, the authors strongly recommend referral for a PSG if there is any suspicion of OSAS.
Immune Response to Experimentally Induced Infection with Respiratory Syncytial Virus: Possible Role in the Development of Pulmonary Disease (1989)

Groups of mice were immunized intraperitoneally with HEp-2 lysate or respiratory syncytial virus (RSV)-infected HEp-2 cells with or without adjuvant(s). The animals were subsequently challenged intranasally (i.n.) with RSV and/or HEp-2 lysate and studied for RSV shedding in the lung, antigen-specific antibody response and pulmonary histopathology. A significant decrease in virus shedding was detected in each of four groups of animals immunized with a virus preparation and in two of four groups that received a HEp-2 lysate. Mice immunized with adjuvant(s) developed higher antibody-specific responses. All vaccinated animals developed pulmonary histopathology only on subsequent i.n. inoculation with RSV and/or HEp-2 lysate. Denatured extracts of purified RSV, HEp-2, BALB/c lung, cotton rat lung, Buffalo green monkey kidney and human buccal epithelium were tested for reactivity against the sera of immunized mice by an immunoblot method. Sera from all groups of immunized mice reacted with the extracts tested. The data suggest a possible role of reactivity to viral as well as non-viral components in the pathogenesis of RSV vaccine-induced pulmonary inflammation in the mouse model system.
A consideration of learning in speech recognition from the viewpoint of AI class-description learning (2003)

The learning mechanism used in a user-adaptive speech recognizer based on the subspace method is treated. Comparing the subspace learning system with the AI (artificial intelligence) learning system ARCH, the following points are made: (1) subspace learning using covariance matrix modification and KL-expansion is a kind of class-description learning, as found in ARCH. The subspace method focuses on feature extraction for powerful pattern class representation, but does not involve only pattern classification; (2) the concept of near-miss in ARCH can be simulated with the subspace method; (3) M. Minsky's recent (1985) concept 'uniframe', which represents a meaning of a class, is obtained as a subspace with KL-expansion.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
