A real-time scheduling policy for multimedia applications on broadcast networks (2002)

Multimedia applications have become some of the most important applications on high speed local and metropolitan area networks. One of the major characteristics of multimedia traffic is the real-time constraint of packets. Furthermore, in multimedia applications, packets of different applications may have different levels of priority. Hence, a proper scheduling policy is necessary to schedule packets with different priorities and real-time constraints. This paper presented a scheduling policy for real-time traffic with priorities on broadcast networks to reduce the probability of packet loss due to exceeding the real-time constraint. Moreover, if packet loss is unavoidable, this scheduling policy will avoid dropping the packets with high priorities.
Preclinical Development of the Novel Chk1 Inhibitor SCH900776 in Combination with DNA-Damaging Agents and Antimetabolites (2011)

Many anticancer agents damage DNA and arrest cell-cycle progression primarily in S or G(2) phase of the cell cycle. Previous studies with the topoisomerase I inhibitor SN38 have shown the efficacy of the Chk1 inhibitor UCN-01 to overcome this arrest and induce mitotic catastrophe. UCN-01 was limited in clinical trials by unfavorable pharmacokinetics. SCH900776 is a novel and more selective Chk1 inhibitor that potently inhibits Chk1 and abrogates cell-cycle arrest induced by SN38. Like UCN-01, abrogation of SN38-induced arrest enhances the rate of cell death but does not increase overall cell death. In contrast, SCH900776 reduced the growth-inhibitory concentration of hydroxyurea by 20- to 70-fold. A similar magnitude of sensitization was observed with cytarabine. A 5- to 10-fold sensitization occurred with gemcitabine, but no sensitization occurred with cisplatin, 5-fluorouracil, or 6-thioguanine. Sensitization occurred at hydroxyurea concentrations that marginally slowed DNA replication without apparent activation of Chk1, but this led to dependence on Chk1 that increased with time. For example, when added 18 hours after hydroxyurea, SCH900776 induced DNA double-strand breaks consistent with rapid collapse of replication forks. In addition, some cell lines were highly sensitive to SCH900776 alone, and these cells required lower concentrations of SCH900776 to sensitize them to hydroxyurea. We conclude that some tumors may be very sensitive to the combination of SCH900776 and hydroxyurea. Delayed administration of SCH900776 may be more effective than concurrent treatment. SCH900776 is currently in phase I clinical trials, and these results provide the rationale and schedule for future clinical trials.
Second order coherence of broadband down-converted light on ultrashort time scale determined by two photon absorption in semiconductor (2010)

We study the photon correlation properties of broadband parametric down-converted light. The measurement of the photon correlation is carried out thanks to a modified Hanbury Brown-Twiss interferometer based on two photon absorption in GaAs detector. Since this method is not affected by the phase matching conditions of the detecting apparatus (so called "final state post-selection"), the detection bandwidth can be extremely large. This is illustrated by studying, with the same apparatus, the degree of second order coherence of parametric light in both degenerate and non-degenerate cases. We show that our experiment is able to determine the coherent as well as the incoherent contributions to the degree of second order coherence of parametric light with a time resolution in the fs range scale.
THE EFFECT OF GROWTH HORMONE ON THE YIELD AND COMPOSITION OF COWS' MILK (1957)

SUMMARY Using a single injection technique, a study has been made of the effect of growth hormone (GH) on the yield and composition of cows' milk. Six lactating cows comprising three sets of identical twins each received six different injection levels during a 78-day period. Quantities of GH injected ranged from 6·25 to 200 mg in geometric progression, and responses were measured for milk yield (lb.), fat percentage, and solids-not-fat percentage, together with the derivatives of these three. Quantities of food consumed by the animals were calculated from the weights of food offered and refused, and total dry-matter intakes were derived from dry-matter estimates obtained on every 3rd day. Results from this experiment show that there is a highly significant linear relationship between log weight of GH injected (mg) and the increase in milk yield (lb.) obtained. Significant linear relationships have also been found between log weight of GH injected (mg) and the degree of change obtained in each of the following milk components: water (1b.); fat (1b.); and solids-not-fat (lb.). Further analysis of the data has shown that by increasing the quantity of GH injected, significant increases are produced in the yield of fat (lb.) relative to the yield of non-fatty-solids (lb.). This is attributed to a significant negative relationship between log weight of GH injected (mg) and the extent of the change in the solids-not-fat percentage. Administration of GH produces increases in the efficiency of conversion of food dry matter to milk and the extent of these changes is closely related to those of milk yield. The results are discussed in relation to previously published findings, and possible explanations for some of the phenomena noted are advanced.
Use of Difference near Infrared Reflectance Spectra to Extract Relevant Information from the Spectra of Agro–Food Products (1998)

This paper compares the use of log 1/ R versus standard normal variate (SNV) and Detrending (DT) transformations calculated either of two forms, SNV followed by DT (SNV+DT) or DT then SNV (DT+SNV) for their abilities to enhance interpretation of spectra and to detect areas of maximum differences in composition of two agro–food products (sunflower seed and corn) and their corresponding by-products (sunflower meal and corn gluten feed). The results obtained show that the SNV+DT and the DT+SNV transformations of the raw data make the existing chemical differences between scattering agro–food products more easily interpretable.
Measurement of Magnetic Thin Film Rotational Properties and Uniformity (1963)

A previous paper by the authors [Rev. Sci. Instr. 33, 1429 (1962)] described an instrument which relates magnetization vector position in a thin film to rf mixing behavior under a crossed-wire probe. The instrument permits nondestructive observation of small areas of the film and affords high angular resolution. This paper describes provisions for automatically indicating and recording the magnetization angle as the film is traversed by the probe. These provisions extend considerably the usefulness of the instrument in studies of film behavior and uniformity.
Advances in Hypergolic Propellants: Ignition, Hydrazine, and Hydrogen Peroxide Research (2014)

A review of the literature pertaining to hypergolic fuel systems, particularly using hydrazine or its derivatives and hydrogen peroxide, has been conducted. It has been shown that a large effort has been made towards minimizing the risks involved with the use of a toxic propellant such as the hydrazine. Substitution of hydrazines for nontoxic propellant formulations such as the use of high purity hydrogen peroxide with various types of fuels is one of the major areas of study for future hypergolic propellants. A series of criteria for future hypergolic propellants has been recommended, including low toxicity, wide temperature range applicability, short ignition delay, high specific impulse or density specific impulse, and storability at room temperature.
The design of Interior Permanent Magnet brushless motor control system based on finite element method (2010)

The rotor of IPM (Interior Permanent Magnet) brushless motor is characterized with a high-strength structure so that the magnet is protected from centrifugal separation when running at a high speed; also, as designed a non-concentrically circular rotor to increase the motor torque output, there is a reluctance torque produced by the salient poles effect in addition to the electromagnetic torque generated by the interactive reaction between the magnet and the coil; however, such a consequence will lead to an increase of the cogging torque. Thus, this research explored the salient-pole interior permanent magnet by going through the modifications of appearance dimensions of motor rotor, application of equivalent magnetic-circuit analysis and finite element method to analyze the cogging torque in a bid to make the objective toward the cogging torque reduction in interior permanent magnet brushless motor achievable.

The blood-administering assessment program described above has improved transfusion practice, reduced the number of near-miss events, and may have prevented mistransfusions.
Association of Dopamine Transporter Reduction With Psychomotor Impairment in Methamphetamine Abusers (2001)

Methamphetamine is a popular and highly addictive drug of abuse that has raised concerns because it has been shown in laboratory animals to be neurotoxic to dopamine terminals. The authors evaluated if similar changes occur in humans and assessed if they were functionally significant.Positron emission tomography scans following administration of [(11)C]d-threo-methylphenidate (a dopamine transporter ligand) measured dopamine transporter levels (a marker of dopamine cell terminals) in the brains of 15 detoxified methamphetamine abusers and 18 comparison subjects. Neuropsychological tests were also performed to assess motor and cognitive function.Methamphetamine abusers showed significant dopamine transporter reduction in the striatum (mean differences of 27.8% in the caudate and 21.1% in the putamen) relative to the comparison subjects; this reduction was evident even in abusers who had been detoxified for at least 11 months. Dopamine transporter reduction was associated with motor slowing and memory impairment.These results provide evidence that methamphetamine at dose levels taken by human abusers of the drug leads to dopamine transporter reduction that is associated with motor and cognitive impairment. These results emphasize the urgency of alerting clinicians and the public of the long-term changes that methamphetamine can induce in the human brain.
Phosphorescent Emission from Polymeric Light-Emitting Diodes Doped with Chrysene-d<sub>12</sub> (1999)

We present electroluminescence studies of chrysene-d 12 which has both high phosphorescence (ϕ Ph =25%) and high fluorescence quantum yields (ϕ Fl =40%) (at 77 K). Light-emitting diodes were fabricated utilizing a simple single layer device structure consisting of a hole-transporting polymer matrix poly(methylphenylsilane) doped with chrysene-d 12 . We show that the spectrum, temperature dependence and temporal characteristics of the electroluminescence emission indicate that it originates from the triplet excited state of chrysene-d 12 .
The subscriber loop bridge-lifting problem and some methods of solution (1961)

To the nontelephone engineer, the title of this paper may suggest difficulties involved either in raising a drawbridge or removing some dental hardware. Actually, bridge lifting is a telephone problem in exchange switching and subscriber loop layout.
Subcellular proteomics (2003)

The step from the analysis of the genome to the analysis of the proteome is not just a matter of numerical complexity in terms of variants of gene products that can arise from a single gene. A significant further level of complexity is introduced by the supramolecular organization of gene products because of protein-protein interactions or targeting of proteins to specific subcellular structures. There is currently no single proteome analysis strategy that can sufficiently address all levels of the organization of the proteome. To approach an appropriate analytical complement for the interrogation of the proteome at all of the levels at which it is organized, there emerges the need for a whole arsenal of proteomics strategies. The proteome analysis at the level of subcellular structures (that can be enriched by subcellular fractionation) represents an analytical strategy that combines classic biochemical fractionation methods and tools for the comprehensive identification of proteins. Among the key potentials of this strategy is the capability to screen not only for previously unknown gene products but also to assign them, along with other known, but poorly characterized gene products, to particular subcellular structures. Furthermore, the analysis at the subcellular level is a prerequisite for the detection of important regulatory events such as protein translocation in comparative studies. This review is meant to give an overview on recent key studies in the field of proteome analysis at the level of subcellular structures, and to highlight potentials and requirements.
Improvement of power amplifier efficiency by reactive Chireix combining, power back-off and differential phase adjustment (2006)

An interesting effect of output power back-off (OPBO) efficiency improvement is presented which is present if 2 power amplifiers (PA) utilizing a reactive output Chireix coupling are combined with input power back-off and differential phase adjustment for maximum efficiency peaking. The capability of significant efficiency improvement at power backoff is demonstrated and validated by means of simulations and measurements. The new design method delivers a power added efficiency (PAE) of 48% at 6dB OPBO and 35% at 10dB OPBO for a 25.7W Si-LDMOS PA at 2.14 GHz for a WCDMA basestation application
Genetic Variations and Haplotypes of CYP2C19 in a Japanese Population (2005)

Forty-eight single nucleotide variations, including 27 novel ones, were found in the 5'- regulatory region, all of the exons and their surrounding introns of CYP2C19 in 253 Japanese subjects (134 diabetic patients and 119 healthy volunteers). Identified novel variations were as follows: -2772G>A, 2767_-2760delGGTGAACA, -2720T>C, -2547delG, -2545G>T, -2545_-2544 delGC, and -2040C>T in the enhancer region; -778C>T, -777G>A, -529G>C, -189C>A, and -185A>G in the promoter region; 151A>G (S51G), 481G>C (A161P), 986G>A (R329H), 1078G>A (D360N), and 1119C>T (D373D) in the exons, and IVS1+128T>A, IVS3+163G>A, IVS4+271A>G, IVS5-49A>G, IVS6-210C>T, IVS6-196T>A, IVS6-32T>A, IVS7+84G>A, IVS7-174C>T, and IVS8+64C>T in the introns. Since we found no significant differences in the variation frequencies between healthy volunteers and diabetic patients, the data for all subjects were treated as one group in further analysis. The allele frequencies were 0.265 for IVS6-196T>A, 0.045 for -2772G>A and -2720T>C, 0.024 for -2040C>T, 0.014 for IVS7-174C>T, 0.010 for -529G>C, 0.006 for IVS1+128T>A and 481G>C (A161P), 0.004 for -2767_-2760delGGTGAACA and IVS6-210C>T, and 0.002 for the other 17 variations. In addition, the two known nonsynonymous single nucleotide polymorphisms, 681G>A (splicing defect, (*)2 allele) and 636G>A (W212X; (*)3 allele) were detected at 0.267 and 0.128 frequencies, respectively. No variation was detected in the known binding sites for constitutive androstane receptor and glucocorticoid receptor. Linkage disequilibrium analysis showed several close linkages of variations throughout the gene. By using the variations, thirty-one haplotypes of CYP2C19 and their frequencies were estimated. Our results would provide fundamental and useful information for genotyping CYP2C19 in the Japanese and probably other Asian populations.
Multi-table search for B-tree files (1979)

A new method of organizing index entries in nodes of a B-tree is presented. The method is designed specifically to work with variable length keys. Thus it is particularly suited to take advantage of the variable length entries that result when key compression techniques are used. The paper analyses the characteristics of compressed keys. Based on this analysis, it is shown that the method results in significant space savings, leading to reduced disk accesses during random searches of a B-tree organized file. The search algorithms are shown to be competitive with the best of previous methods for treating variable length entries.
Urban Change Detection Based on Coherence and Intensity Characteristics of SAR Imagery (2008)

In this paper, an unsupervised change-detection approach was proposed to detect new urban areas from multi-temporal SAR images. The novelty of the proposed approach is the joint use of coherence and intensity characteristics of SAR imagery. The approach involves two main steps: (a) the extraction of difference feature containing information on changed areas, and (b) the unsupervised two-dimensional (2D) thresholding. First, two difference features based on the concepts of long-term coherence and backscattering temporal variability are extracted from a series of multitemporal SAR images. Then, the resulting features that represent the INSAR signal temporal variability of changed areas are merged, and a 2D thresholding technique based on the maximum 2D Renyi’s entropy criterion is developed to obtain the change-detection results. The effectiveness of the proposed approach is confirmed with experimental results obtained from a set of six ERS-1/2 SLC SAR images acquired in Shanghai, China.

MAGNETOOPTICAL PROPERTIES OF RARE-EARTH IONS IN FERROMAGNETIC CRYSTALS (1963)

ABS>A quantitative calculation was made of the frequency dependence of the Faraday effect in europium ferrite garnet caused by exchange interaction between the rareearth and iron sublattices of the ferrite garnet. Assuming cubic symmetry of the crystal field, the peculiarities of the polarized absorption spectra and luminescence of rareearth ions in the ferromagnetic crystal were analyzed. It is shown with the aid of an external magnetic field that it is possible to modify the spectrum of rare-earth ions in a ferromagnet, which suggests the use of the method for creating a controlled laser in a ferromagnetic crystal.

Sensitivity of GNSS-R Spaceborne Observations to Soil Moisture and Vegetation (2016)

Global navigation satellite systems-reflectometry (GNSS-R) is an emerging remote sensing technique that makes use of navigation signals as signals of opportunity in a multistatic radar configuration, with as many transmitters as navigation satellites are in view. GNSS-R sensitivity to soil moisture has already been proven from ground-based and airborne experiments, but studies using space-borne data are still preliminary due to the limited amount of data, collocation, footprint heterogeneity, etc. This study presents a sensitivity study of TechDemoSat-1 GNSS-R data to soil moisture over different types of surfaces (i.e., vegetation covers) and for a wide range of soil moisture and normalized difference vegetation index (NDVI) values. Despite the scattering in the data, which can be largely attributed to the delay-Doppler maps peak variance, the temporal and spatial (footprint size) collocation mismatch with the SMOS soil moisture, and MODIS NDVI vegetation data, and land use data, experimental results for low NDVI values show a large sensitivity to soil moisture and a relatively good Pearson correlation coefficient. As the vegetation cover increases (NDVI increases) the reflectivity, the sensitivity to soil moisture and the Pearson correlation coefficient decreases, but it is still significant.
Infrared spectroscopy for chemical agent detection using tailored hypersorbent materials (2015)

We report long-wave infrared (LWIR, 5-15 μm) and mid-wave infrared (MWIR, 2.5 – 5 μm) differential absorption spectra of different nerve agent simulants and common solutes sorbed to poly(methyldi(1,1,1-trifluoro-2-trifluoromethyl- 2-hydroxypent-4-enyl)silane, HCSFA2, an NRL developed hypersorbent polymer. HCSFA2 is a strong hydrogen-bond acidic polymer which exhibits large gas-polymer partitions for a variety of hazardous chemicals with hydrogen-bond basic properties such as the phosphonate ester G-nerve agents or their simulants. The measured ATR-FTIR differential absorption spectra show complex fingerprint signal changes in the resonances for the sorbent material itself, as well as new resonances arising from chemical bonding between the solute or analyte and the sorbent or the solute itself being present in the sorbent.
Human γ δ T cell subset-proliferative response to malarial antigen in vitro depends on CD4+ T cells or cytokines that signal through components of the IL-2R (1996)

We examined the cellular and molecular basis of the proliferative response of human gamma delta T cells in cultures of PBMC stimulated with blood-stage Plasmodium falciparum malarial Ag. Flow cytometry revealed that maximal gamma delta T cell proliferation occurs after maximal CD4+ alpha beta T cell proliferation. Depletion of CD4+ T cells from PBMC before stimulation with malarial Ag markedly reduces the number of proliferating gamma delta T cells, which suggests that CD4+ T cells function in providing help to gamma delta T cells to respond to this parasite Ag. Removal of gamma delta T cells, however, did not alter the expansion of the CD4+ T cell subset. The addition of exogenous IL-2, IL-4, or IL-15 restored the capacity of gamma delta T cells to proliferate in Ag-stimulated cultures of PBMC depleted of CD4+ T cells. mAbs specific for the alpha- and beta-subunits of the IL-2 receptor inhibit the gamma delta T cell subset expansion in cultures stimulated with malarial Ag. Taken together, these findings suggest that the proliferation of gamma delta T cells in response to malarial Ag is dependent on the presence of CD4+ alpha beta T cells, but the requirement for CD4+ alpha beta T cells can be met by cytokines that use the IL-2R.
Composition of the leaf wax of Little Club wheat (1969)

Leaf wax of Little Club wheat is composed of: hydrocarbons (8–15%); esters (20–26%); alcohols (25–42%); acids (2%); β-diketone (6–10%); hydroxy β-diketones (9–16%); and unidentified material (9–12%). The esters are mainly octacosanol esters of C 14 to C 32 fatty acids but lesser amounts of esters of trans 2-tetracosenoic and trans 2-docosenoic acids also occur. The free alcohols are almost entirely octacosanol. The β-diketone is hentriacontane-14,16-dione and the hydroxy-β-diketones are a 1:1 mixture of 8- and 9-hydroxyhentriacontane-14,16-diones.
