Sequence retrieval by contents through spatio temporal indexing (2002)

Sequence retrieval by contents can be supported with effective user interaction by indexing frame sequences through a symbolic representation of their contents. A language for the symbolic representation of the contents of image sequences is presented. This language incorporates and extends concepts of temporal logic so as to deal in a uniform way with both temporal and spatial features of digital video sequences. A prototype system which relies on the above language and supports retrieval by contents of image sequences through visual interaction is also briefly described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
An Antigenic Marker for Human Thymic Lymphocytes (1973)

Abstract Murine thymocytes and thymus-derived lymphocytes possess antigens not normally represented on most other tissues. Antigens of the TL (1), Ly (2), and θ (3) systems can be detected by isoimmunizations with mouse strains differing at the appropriate genetic locus. By immunization of rabbits with mouse lymphoid cells, followed by appropriate absorption procedures, reagents have been produced which can also identify and selectively lyse several different lymphocyte populations (4–6). The availability of immunologic reagents for detecting antigenic differences has greatly facilitated investigations of functional differences among subpopulations of mouse lymphocytes. Similar reagents have not been available previously for the study of human lymphocyte subpopulations. We have investigated the usefulness of absorbed heterologous antihuman thymocyte serum for the detection of antigenic heterogeneity in human lymphoid cells. Thymus cells were obtained from fetuses and from infants under 1 year of age. Rabbits were injected in the foot pads with 109 cells emulsified with complete Freund's adjuvant. They were given an intravenous injection of 10 9 cells on day 14 and were bled on day 21. Those sera showing a high titer of complement dependent antibody against human peripheral blood lymphocytes were pooled, and the gamma, globulin was precipitated with ammonium sulfate. The precipitate was made up to a concentration of 8 mg/ml in saline containing 30% v/v human albumin. All sera were Millipore filtered and stored at –20°C.
Implementation of sub-10 ns serial access mode to a standard 64-Mb DRAM (2002)

Presents a simple architecture achieving high-speed serial read/write operations as an additional function mode for low-cost standard DRAMs (dynamic random-access memories). In the architecture, an on-chip double-bank interleaved data processing scheme is coupled with a preceding column selecting method, and consequently a twice-higher bandwidth than that in a conventional fast-page mode can be obtained with a few extra circuits. Implementing the architecture on an experimental 64-Mb DRAM, sub-10-ns serial access has been demonstrated with only a 3% area penalty.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
TCP SPC: Statistic Process Control for Enhanced Transport over Wireless Links (2008)

In this paper, we propose a novel TCP congestion control algorithm, named TCP SPC, which improves upon the performance of TCP Reno in wireless networks. TCP SPC exploits statistic process control (SPC) methods that have been used effectively in a variety of monitoring and control applications other than TCP. A TCP SPC sender uses RTT statistics to judge the network status, whereby the congestion window can be adjusted more intelligently. Comparing with conventional TCP, TCP SPC is more robust to sporadic losses due to wireless channel errors. Such errors often cause conventional TCP to over react, leading to unnecessary congestion window reduction. TCP SPC controls the congestion window in a way that is completely transparent to intermediate nodes and the destination. Therefore, it is compatible with any TCP implementation at the destinations. In this paper, we introduce TCP SPC and its implementation in a simulation environment. The simulation results show that TCP SPC can significantly improve throughput and fairness, especially in wireless networks with high-error links.
Alkaline phosphatase isoenzymes resolved by electrophoresis on lectin-containing agarose gel. (1986)

Abstract With this electrophoretic method the liver, biliary, and bone isoenzymes of alkaline phosphatase are clearly separated on agarose gels. Wheat-germ lectin, incorporated in the gel matrix, binds the bone isoenzyme selectively, forming a precipitate near the origin. Neither liver nor biliary isoenzyme is affected. Activity staining with an indigogenic dye substrate reveals the liver isoenzyme migrating nearest the anode, followed by the biliary and bone isoenzymes. Results are generally similar to those of electrophoresis on cellulose acetate. However, the lectin-agarose gels better resolve the liver and bone isoenzymes, and heat treatment of samples is not required before electrophoresis.
Quinazoline antifolates inhibiting thymidylate synthase. Variation of the amino acid (1986)

Five new analogues (1c-g) of the antifolate N10-propargyl-5,8-dideazafolic acid (1a) are described in which the benzoyl-L-glutamate moiety was replaced by benzoic acid (desglutamyl-N10-propargyl-5,8-dideazafolic acid), benzoyl-L-aspartate, 4-phenylbutyrate, benzoylglycine, and benzoyl-L-alanine. The esters of the appropriate 4-aminophenyl (benzoyl) starting materials were sequentially alkylated upon nitrogen, first with a propargyl halide and then with 2-amino-6-(bromomethyl)-4-hydroxyquinazoline hydrobromide. Saponification of the antifolate esters so produced gave the desired analogues. The new derivatives (1c-g) and also the known diethyl ester of 1a (1b) were tested for their inhibition of purified L1210 thymidylate synthase (TS) and for their inhibition of the growth of L1210 cells in culture. The TS inhibition of the analogues 1b-g was estimated by calculating the inverse relative potency, defined as the ratio IC50(compound)/IC50(1a). The results obtained were as follows: greater than 62, 84, 9, 333, 21, and 5, respectively. All were thus less inhibitory than 1a. None of the compounds improved upon 1a in inhibiting the growth of L1210 cells in culture.
Minimum-structure enkephalin analogs incorporating L-tyrosine, D (or L)-phenylalanine, and a diamine spacer (1989)

In order to test the theory that high mu-activity of opioid peptides could be elicited by the presence of an amino-terminal L-Tyr residue and a Phe aromatic ring held in the proper relative spatial disposition, a novel series of hybrid retro peptides were prepared in which L-Tyr was linked to N-acyl Phe through a variety of diamine spacers. These compounds were evaluated for opioid agonist and antagonist activity in the guinea pig ileum (GPI) in vitro assay. Analogues containing a 1,2-ethanediamine spacer, which conferred a Tyr-Phe separation distance closest to that found in Phe3 opioid peptides, were more potent agonists than the corresponding analogues containing a 1,3-propanediamine spacer. Agonist activity was observed for both L-Phe and D-Phe analogues, consistent with the known activity for both Phe stereochemistries for certain Phe3 opioid peptide analogues. Concerning the diamine spacer, conformational constraints imposed by 4-aminopiperidine and 4-(aminomethyl)piperidine as well as the presence of a hydroxyl group eliminated activity, but the presence of gem-dimethyl substitution next to the nitrogen attached to Tyr increased activity substantially for the D-Phe derivatives. Removal of the N-acetyl group from Phe did not eliminate activity. Naloxone Ke values determined for six of the most potent analogues are indicative of predominantly mu-agonism, but the D-Phe compounds 3a and 6a (1.4-2.1 nM) appear to be more mu-selective than the L-Phe compounds 2b, 3b, 5b, and 6b (3.3-4.4 nM), even though the latter are more potent agonists. Compounds 3a and 3b, which were found to be 10 and 21 times more potent, respectively, than morphine in the GPI, are two of the most structurally simple yet potent opioid peptide analogues described to date.
Nitroimidazoles, XIV: Synthesis of 4‐Nitroimidazoles with 1‐Substituents Containing Acid, Ester or Phenol Functions, and Radiosensitizing Efficiency of Some of These Compounds (1992)

1,4-Dinitroimidazole and 1,4-dinitro-2-methylimidazole were reacted with aminocarboxylic acids and their esters, aminosulfonic acids, and aminophenol to obtain the corresponding 1-substituted-4-nitroimidazoles. The radiosensitizing efficiency of some esters of 2-(4-nitro-1-imidazolyl)alkanecarboxylic acids was tested.
Activation of the extracellular signal-regulated kinase pathway is differentially required for TCR-stimulated production of six cytokines in primary T lymphocytes. (1998)

The extracellular signal-regulated kinase (ERK) signaling pathway is strongly activated in response to TCR stimulation in normal T cells. However, the extent to which activation of the ERK pathway is necessary for TCR-stimulated cytokine production is not clear. We have addressed this question by use of two separate methods to interfere with TCR activation of the ERK cascade. The first approach utilized transient expression of a catalytically inactive form of mitogen-activated/ERK 1 (CI-MEK1), while the second involved using the MEK1- and MEK2-specific inhibitor PD98059 to block ERK activation by the TCR. In order to assess the requirement for ERK activation in T cell cytokine production, we have measured the effect of ERK inhibition upon the production of six cytokines, IL-3, IL-4, IL-5, IL-10, granulocyte macrophage colony stimulating factor (GM-CSF) and IFN-gamma, by newly activated normal mouse T cells in response to TCR stimulation. The results of experiments using both methods to block ERK activation have revealed a requirement for intact ERK signaling for the full elicitation of TCR-stimulated cytokine production. Dose-response analyses using the MEK inhibitor PD98059 showed that the TCR-stimulated production of all cytokines measured was affected by this treatment. However, the production of IL-3 and IL-4 was only partially dependent upon ERK activation, whereas IL-5, IL-10, IFN-gamma and GM-CSF production was severely affected by diminished ERK activation. We conclude that the ERK pathway is differentially involved in the activation of different cytokine genes in normal T cells.
Advanced Aloha with SIC for Beaconing in a MANET (2011)

Beaconing, the broadcast of information from one user of a network to all others within a certain neighborhood is required for a number of applications. This paper focuses on beaconing in a wireless, infrastructureless network with mobile users. In such a scenario, we analyze the performance of Advanced Aloha, the combination of Aloha with strong protection of messages against interference. Such protection is achieved through coding and other measures. Together with successive interference cancellation, it allows to resolve collisions. Analytical results will be presented for perfect interference cancellation. These include the maximum amount of messages per area and time for which a given communication range may be achieved, as well as the resulting maximum spectral efficiency at a receiver. Signal propagation according to a path loss exponent is taken into account together with a radio horizon limiting node visibility. Notably, this leads to results applicable to freespace propagation in contrast to other work ignoring the radio horizon.
Parameters that control pulsed electron beam ablation of materials and film deposition processes (2003)

Conditions for ablation of materials and film deposition were analyzed for a pulsed (∼100 ns) electron beam produced by a channel-spark source. For dielectric materials, we found the existence of an optimal source voltage related to the saturation of the pulse current. Our analysis indicates a larger ablated mass, smaller optimal deposition rates (∼0.25 Å/pulse), and a larger optimal target to substrate distance relative to pulsed laser deposition process.
T <sub>1</sub> cortical hypointensities and their association with cognitive disability in multiple sclerosis (2010)

Although T( 1) hypointense NLs may be present in a relatively high proportion of multiple sclerosis patients, the impact that they have in cognitive impairment is not independent from white matter disease.
Data in Society (2019)

Statistical data and evidence-based claims are increasingly central to our everyday lives. This book charts the recent explosion in sources of data, including those precipitated by global development and technological change. It sets out changes and controversies related to data harvesting and construction, dissemination and data analytics by a range of private, governmental and social organisations in multple settings.
Programmable synaptic weights for an aVLSI network of spiking neurons (2006)

We describe a spiking neuronal network which allows local synaptic weights to be assigned to individual synapses. In previous implementations of neuronal networks, the biases that control the parameters of a particular synapse are global to all synapses of the same type regardless of the target neuron. In this new implementation, the parameters for a synapse are set by on-chip digital-analog-converter (DAC) circuits, and the DACs are updated before the selected synapses are activated. Results from the fabricated chip show that the local weights are programmable and the DACs settle in the order of microseconds. These on-chip DACs allow the user to program a selected synaptic weight for connections between neurons and they can also be used for mismatch calibration.
Increase in bicycloprostaglandin E<sub>2</sub> metabolite in congestive heart failure in response to captopril (1989)

Vasodilating prostaglandins may be increased in patients with chronic congestive heart failure (CHF) to balance out the effects of vasoconstricting forces. Significant increases in plasma levels of bicycloprostaglandin E2 metabolite (PGEm), a chemically stable degradation product of the vasodilating prostaglandin E2, were found in response to captopril (39.4 +/- 7.8 vs. 46.2 +/- 8.2 pg/ml; p less than 0.01). With chronic captopril treatment bicyclo-PGEm remained elevated for 12 h after the last dose after 1 and 2 months (75.5 +/- 5.5; p less than 0.05 and 72.1 +/- 6.3 pg/ml; p less than 0.05, respectively). Upon readministration of captopril during chronic captopril treatment the significant increase of bicyclo-PGEm in response to captopril was sustained, as were changes in plasma renin activity, angiotensin II, and blood pressure. Plasma catecholamines were unchanged with captopril or decreased slightly, vasopressin remained moderately increased throughout. Taken together, the results suggest that vasodilating prostaglandin E2 production might play a part in captopril's beneficial action in chronic congestive heart failure.
Design and simulation of high magnetic gradient device for effective bioparticles trapping (2012)

In this work, a design and simulation of high magnetic gradient device for effective bioparticles trapping is reported. The planar square-shaped microcoil and a V-shaped nickel iron (NiFe) alloy core is designed to guide and confine the magnetic flux lines through its small tip area and thus enhance the magnetic flux density and its gradient. The effects of core structure and coil parameters are analyzed using Finite element analysis (FEA) of two dimensional axial symmetry modeling. The simulation results revealed that the V-shaped magnetic core has significantly increased the magnetic flux density, its gradient and the magnetic force affecting on the beads sample. The highest magnetic flux density value, Bnorm is 66 mT is achieved for microcoil turns of N = 20, thickness of h = 5 μm, width and spacing of w = s = 50 μm and on tip surface area of 1 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Furthermore, a maximum magnetic force value of Fm = 1700 pN which is much higher than the drag force experienced by the magnetic beads in the microchannel has also been observed. Therefore, a promising effective trapping of the magnetic beads in the microfluidic channel is enable with this high magnetic gradient device design.
A Liquid‐Metal‐Based Magnetoactive Slurry for Stimuli‐Responsive Mechanically Adaptive Electrodes (2018)

Electrical communication between a biological system and outside equipment allows one to monitor and influence the state of the tissue and nervous networks. As the bridge, bioelectrodes should possess both electrical conductivity and adaptive mechanical properties matching the target soft biosystem, but this is still a big challenge. A family of liquid-metal-based magnetoactive slurries (LMMSs) formed by dispersing magnetic iron particles in a Ga-based liquid metal (LM) matrix is reported here. The mechanical properties, viscosity, and stiffness of such materials rapidly respond to the stimulus of an applied magnetic field. By varying the intensity of the magnetic field, regulation within a factor of 1000 of the Young's modulus from ≈kPa to ≈MPa, and the ability to reach GPa with more dense iron particles inside the LMMS are demonstrated. With the advantage of high conductivity of the LM matrix, the functions of the LMMS are not only limited to the soft implanted electrodes or penetrating electrodes in biosystems: the electrical response based on the LMMS electrodes can also be precisely tuned by simply regulating the applied magnetic field.
The effect of deuterium passivation at different steps of CMOS processing on lifetime improvements of CMOS transistors (1999)

We have investigated the effect of deuterium sintering for reliability lifetime improvement of CMOS transistors with nitride sidewall spacers. SIMS measurements show that lifetime improvements of wafers with deuterium sintering at the Metal-1 and Metal-4 steps are directly related to the deuterium incorporation at the SiO/sub 2//Si interface.
Synthesis and Characterization of Highly Luminescent CdSe−Core CdS/Zn<sub>0.5</sub>Cd<sub>0.5</sub>S/ZnS Multishell Nanocrystals (2005)

We report on the preparation and structural characterization of CdSe nanocrystals, which are covered by a multishell structure from CdS and ZnS. By using the newly developed successive ion layer adhesion and reaction (SILAR) technique, we could gradually change the shell composition from CdS to ZnS in the radial direction. Because of the stepwise adjustment of the lattice parameters in the radial direction, the resulting nanocrystals show a high crystallinity and are almost perfectly spherical, as was investigated by X-ray diffraction and electron microscopy. Also, due to the radial increase of the respective valence- and conduction-band offsets, the nanocrystals are well electronically passivated. This leads to a high fluorescence quantum yield of 70-85% for the amine terminated multishell particles in organic solvents and a quantum yield of up to 50% for mercapto propionic acid-covered particles in water. Finally, we present experimental results that substantiate the superior photochemical and colloidal stability of the multishell particles.

Applying adjustable-speed drives to three-phase induction NEMA frame motors (1997)

Band Structure of GaP<sub>1-x</sub>N<sub>x</sub>(x= 0.25, 0.5, 0.75) Ordered Alloys: Semiempirical Tight-Binding Calculation (1998)

A semiempirical tight-binding calculation of the electronic structure of GaP 1- x N x ordered alloys ( x =0.25, 0.5, and 0.75) has been performed. The bowing parameter of the band gap is extremely large (7.6 and 3.2 eV for the \varGamma– X and the \varGamma–\varGamma transitions, respectively), which explains the experimental band gap reduction with increasing x when x <0.03 as observed by photoluminescence (PL) measurements [S. Miyoshi, H. Yaguchi, K. Onabe, R. Ito and Y. Shiraki: Appl. Phys. Lett. 63 (1993) 3506]. We have clarified that the large bowing originates from the large valence band (VB) offset between GaP and GaN (3.66 eV by Harrison's rule). The calculated band lineup of the GaP 1- x N x alloy indicates that not only the GaP 1- x N x –GaP heterojunction but also the GaP 1- x N x –GaN heterojunction will show a type-II transition. The electronic structures of GaAs 1- x P x and GaAs 1- x Sb x ordered alloys have also been calculated, and the values were consistent with the experimental band gap. The consistency confirms the validity of our calculation. The calculation is also applied to the electronic structure of a GaAs 1- x N x ordered alloy ( x =0.25, 0.5, and 0.75) which is also found to have large bowing parameters (4.0, 8.5, and 6.2 eV for the \varGamma–\varGamma, \varGamma– X , and \varGamma– L transitions, respectively) probably due to the large VB offset between GaAs and GaN.
Microbial Alteration of Subsurface Natural Gas Accumulations (1984)

Bacterial alteration of subsurface reservoired hydrocarbon accumulations extends into the range of the C1-C4 gaseous hydrocarbons, preferentially attacking the wet gas components in most instances. During the initial stages of bacterial gas alteration, propane seems to be selectively attacked, resulting in anomalous propane carbon isotopic compositions as well as unusual carbon isotopic distributions among the wet gas components. Extensive bacterial alteration appears to be capable of removing all but traces of the wet gas components, resulting in a dry gas that could be confused with overmature dry gas whose wet components have undergone extensive thermal cracking. Recognition of microbial alteration in subsurface reservoired hydrocarbon gas accumul tions is important for both correlation purposes and maturity estimates.
