Electromagnetic field interactions with biological systems <sup>1</sup> (1993)

This is a report on Symposia organized by the International Society for Bioelectricity and presented at the 1992 FASEB Meeting. The presentations summarized here were intended to provide a sampling of new and fruitful lines of research. The theme topics for the Symposia were cancer, neural function, cell signaling, pineal gland function, and immune system interactions. Living organisms are complex electrochemical systems that evolved over billions of years in a world with a relatively simple weak magnetic field and with few electromagnetic energy emitters. As is characteristic of living organisms, they interacted with and adapted to this environment of electric and magnetic fields. In recent years there has been a massive introduction of equipment that emits electromagnetic fields in an enormous range of new frequencies, modulations, and intensities. As living organisms have only recently found themselves immersed in this new and virtually ubiquitous environment, they have not had the opportunity to adapt to it. This gives us, as biologists, the opportunity to use these electromagnetic fields as probes to study the functioning of living systems. This is a significant opportunity, as new approaches to studying living systems so often provide the means to make great leaps in science. In recent years, a diversity of biologists have carried out experiments using electromagnetic fields to study the function of living cells and systems. This approach is now becoming quite fruitful and is yielding data that are advancing our knowledge in diverse areas of biology.

Sensitivities of Thromboplastins to Factor VII Deficiency (1971)

Plasma from a factor VII deficient patient was used to compare the sensitivities of thromboplastins from different sources. The results based on time in seconds were compared with those in abnormal control plasmas. The factor VII deficiency was detected with all thromboplastins tested; however, some showed more “sensitivity” than others. Simplastin A was the most sensitive, and the specially prepared brain thromboplastin the least sensitive, to factor VII deficiency.
SYNTHESIS AND PROPERTIES OF l(+)-2,4-DIMETHYL-2-DODECENOIC ACID (1953)

In a recent paper (1) from this laboratory, there was reported the isolation of a C&T acid, termed CzT-phthienoic acid, from a fraction of acids originally separated by Spielman and Anderson (2) from the lipides of the tubercle bacillus. Since this acid, believed to be homogeneous, was found (3) to induce the cellular response originally reported by Sabin (4) for certain acidic components of the tubercle bacillus, its structure was investigated. In a second paper (5), there was proposed for C&-phthienoic acid the partial structural formula, I, which specified all structural features
InP HBT Production Process (2001)

The need for higher performance electronics for space and defense applications has driven the development of InP heterojunction technologies. For the past 10 years, TRW has been developing InP HBT and HEMT technologies for mission critical applications [1– 3]. Consistent and continuous improvements in the basic MBE structure and process technology have enhanced device and circuit performance, producibility, and reliability such that InP is being successfully used for many space and defense applications. At TRW we have established an InP HBT high yield and manufacturable production process. The production capability of InP technologies is dependent on three core capabilities: stable epitaxial material, stable frontside process, and stable backside process.
Vision Based Control of Autonomous UAV (2016)

This master thesis investigates the problem of making an unmanned aerial vehicle(uav) follow a person or a group of persons while keeping a fixed distance tothe chosen target. The purpose of this thesis is to give a proof of concept prototypeof how such a system would work to achieve that task. The main problemconsists of controlling the uav based on visual input from a camera. With thehelp of a visual object detection and tracking system, the image coordinates ofthe targets can be found. An algorithm was developed to calculate the target’sworld position based on its image coordinates and the world position and orientationof the uav. A control system was implemented that uses that uses thepositional information to set the velocity of the uav, if its position needs to bechanged. Several strategies for handling groups of targets were investigated. Inaddition a simulator was developed that can be used to simulate the image coordinatesof a target when the world position of the target is known. The systemwas tested during live flights, using a high precision motion capture system forreference. The results were mainly positive in showing proof of concept and evenshowing a relatively high level of precision.
Prevalence of Alzheimer??s disease in a retirement community (1987)

In a white, predominantly middle class southern California retirement community, 817 adults aged 65-99 years were evaluated in 1980-1982 in a study designed to assess prevalence of early Alzheimer-type senile dementia. Based on 162 neurologically diagnosed cases, the age- and sex-adjusted prevalence of Alzheimer's disease in the target population was 15.3% (95% confidence interval = 13.0-17.5) among persons aged 65+ years and 35.8% among persons aged 80+ years. Age-adjusted correction for false negatives not detected by a screening procedure yields an estimated prevalence of 16.4% in persons aged 65+ years. Validity of the diagnostic approach was confirmed by a follow-up study. These rates far exceed past prevalence estimates for this disease. Since prevalence of mid- or later stages of Alzheimer's disease may have been underestimated, the high rates in this study may reflect a considerable community burden of early disease. Observed prevalence of Alzheimer-type senile dementia was higher among men than women after adjustment for age, 19.1% and 13.1%, respectively. The female predominance reported in many past clinical surveys may be peculiar to late disease and reflect care-seeking and care-utilization behaviors, rather than differences in incidence.
Faster integer multiplication (2007)

For more than 35 years, the fastest known method for integer multiplication has been the Schönhage-Strassen algorithm running in time O(n log n log log n). Under certain restrictive conditions there is a corresponding Ω(n log n) lower bound. The prevailing conjecture has always been that the complexity of an optimal algorithm is Θ(n log n). We present a major step towards closing the gap from above by presenting an algorithm running in time n log n, 2O(log* n).
New Photocleavable Structures. Diacylgermane-Based Photoinitiators for Visible Light Curing (2008)

As bisacylphosphine oxides are highly efficient, cleavable photoinitiators for visible light curing, we were interested in preparing diacylgermane 2. The UV–vis absorption maximum of the n−π* transition was red-shifted up to 50 nm. Photo-DSC results of 2 showed similar reactivity to bisacylphosphine oxides under broadband irradiation experiments. Irradiation with a dental LED lamp gave significantly improved initiation behavior compared to bisacylphosphine oxides and camphorquinone, especially in aqueous acidic primer formulations. Application-oriented tests in dental adhesive or composite formulations showed sufficient storage stability, high photocuring activity, excellent photobleaching behavior, and mechanical properties of the materials.
Preparation and SO<sub>2</sub> Sorption/Desorption Behavior of an Ionic Liquid Supported on Porous Silica Particles (2009)

The ionic liquid 1,1,3,3-tetramethylguanidinium lactate (TMGL) was supported onto porous silica particles via a facile impregnation−vaporization method. The TMGL-supported particles gave high porosity and large specific surface area. The SO2 sorption/desorption properties of the silica-supported TMGL (TMGL−SiO2) were evaluated, and high SO2 sorption capacity and rate were achieved. Its capacity reached 0.6 g SO2/g TMGL in 15−30 min with pure SO2 gas and 0.15 g SO2/g TMGL in 17 h with a N2/SO2 mixture gas that contained 2160 ppm SO2. The SO2 concentration was reduced to 12.6 ppm after sorption. The TMGL−SiO2 system could be reused for many sorption/desorption cycles without change in its capacity. It was also characterized by good mechanical strength and thermal stability at temperature up to 130 °C. The SO2 sorbent system appears to be useful in gas desulfurization.
A novel method for the efficient and selective identification of 5-hydroxymethylcytosine in genomic DNA (2011)

Recently, 5-hydroxymethylcytosine (5hmC) was identified in mammalian genomic DNA. The biological role of this modification remains unclear; however, identifying the genomic location of this modified base will assist in elucidating its function. We describe a method for the rapid and inexpensive identification of genomic regions containing 5hmC. This method involves the selective glucosylation of 5hmC residues by the β-glucosyltransferase from T4 bacteriophage creating β-glucosyl-5-hydroxymethylcytosine (β-glu-5hmC). The β-glu-5hmC modification provides a target that can be efficiently and selectively pulled down by J-binding protein 1 coupled to magnetic beads. DNA that is precipitated is suitable for analysis by quantitative PCR, microarray or sequencing. Furthermore, we demonstrate that the J-binding protein 1 pull down assay identifies 5hmC at the promoters of developmentally regulated genes in human embryonic stem cells. The method described here will allow for a greater understanding of the temporal and spatial effects that 5hmC may have on epigenetic regulation at the single gene level.
The moisture content of butter and methods of controlling it (1903)

Much American butter has in the past been criticised by commercial judges on account of containing too much moisture (leaky butter, as butter judges term it), when, in reality, it showed by chemical analysis only a low percentage of water. This is undoubtedly due to improper incorporation of the moisture, as much butter, apparently dry, contains a high moisture content.\nIt is also a well known fact that the amount of butter which is being made from a given amount of fat varies a great deal at the different creameries. Some makers are able to produce only 110 pounds of butter from 100 pounds of fat, while some other makers are able to produce 120 pounds of butter of equal commercial quality from the same amount of fat; that is, some are able to get an overrun of only about ten per cent, while some others obtain an overrun of about 20 per cent.
Landmark-based data location verification in the cloud: review of approaches and challenges (2017)

Data storage on the cloud is growing every day and many companies, administrations, and individuals are now outsourcing storage of their data to large-scale Cloud Service Providers (CSP). However, because of today’s cloud infrastructure virtualization, data owners cannot easily know the location where their data are stored. Even in case of the establishment of a strong Service-Level Agreement, which includes an initial guarantee regarding data location, the CSP may then move data to another location, like another country, in order to cut storage costs or for any other reasons, including backup mistakes and fraudulent use of data. Data location verification is required due to legal, privacy, and performance constraints. Recently “Where are my data located in the cloud?” has become a challenge and solutions have been proposed to verify data location, under given assumptions regarding CSP behavior. The objective of this paper is twofold: propose a comprehensive classification of the location verification approaches and discuss their vulnerabilities regarding malicious CSP attacks. Location verification solutions may be Framework-based, Hardware-based or Landmark-based. This paper addresses only landmark-based approaches for their deployment flexibility and low cost.
MDL 26,479: a potential cognition enhancer with benzodiazepine inverse agonist‐like properties (1992)

1. The present study investigated biochemical, electrophysiological and behavioural properties of the novel cognition enhancer, MDL 26,479 (5-(3-fluorophenyl)-2,4-dimethyl-3H-1,2,4-triazole-3-thione). 2. The 5-aryl-1,2,4-triazole, MDL 26,479, potently (0.22 +/- 0.05 mg kg-1) inhibited [3H]-flumazenil (Ro15-1788) binding in mouse cortex but was ineffective in vitro at displacing radioligand binding to the GABAA receptor complex. 3. Parenteral administration of MDL 26,479 (1 mg kg-1) or the benzodiazepine (BZD) inverse agonist methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM) (0.3 mg kg-1) increased cortical ex vivo binding of [3H]-hemicholinium-3 ([3H]-HC-3), a marker for cholinergic activation. This effect of MDL 26,479 was blocked by pretreatment with the antagonist flumazenil (1 mg kg-1). 4. MDL 26,479 (20 microM) and DMCM (1 microM) increased excitation in the hippocampal long-term potentiation (LTP) slice preparation; however, unlike DMCM, the effect of MDL 26,479 was not blocked by flumazenil. 5. In behavioural studies, MDL 26,479 did not exhibit adverse properties characteristic of drugs associated with the GABAA receptor complex. It lacked convulsant, anxiogenic, anxiolytic, or depressant effects. Since MDL 26,479 lacks activity with the BZD receptor in vitro we suggest that it acts via the GABAA receptor complex at another site on this receptor or in an as yet undefined manner or an active metabolite is formed in vivo. 6. Previous work showed that MDL 26,479 enhances learning acquisition in animal models.The present study suggests that at least some of the cognition enhancing properties are due to the enhancement of cortical and hippocampal cholinergic function and LTP.
Optimization of robot hand power grasps (2002)

When an object is grasped by a multifingered hand with power grasp, there are an infinite number of possible power grasp forms, provided by combinations of the hand shape, the contact positions between fingers and the object, and the joint torques of the hand. To plan a power grasp, it is necessary to know, by some prior evaluation which form is most suitable among these forms. This paper proposes a technique for automatically obtaining optimal power grasp. By analyzing the degree of freedom of the force space caused by frictional contacts between fingers and object, the conditions and mechanical properties of power grasp are described. Also, the region of feasible joint torques for power grasp is derived. Then, an optimal power grasp form is defined and its determination procedure is established.
Synthesis and structural study of neutral mononuclear and anionic binuclear 2,4,6-trifluorophenyl derivatives of palladium(<scp>II</scp>). Crystal structure of [P(CH<sub>2</sub>Ph)Ph<sub>3</sub>]<sub>2</sub>[(C<sub>6</sub>F<sub>3</sub>H<sub>2</sub>)<sub>2</sub>Pd(µ-SCN)(µ-NCS)Pd(C<sub>6</sub>F<sub>3</sub>H<sub>2</sub>)<sub>2</sub>] (1990)

Arylation of K2[PdCl4] with Mg(C6F3H2)Br in tetrahydrofuran–dioxane and subsequent addition of either benzonitrile or dibenzylideneacetone (dba) in diethyl ether leads to the formation of labile complexes [Pd(C6F3H2)2(PhCN)2] or [Pd(C6F3H2)2(dba)] respectively. A number of [Pd(C6F3H2)2L2]- type complexes [L = PEt3, AsPh3, P(OMe)3, P(OEt)3, P(OPh)3, L2= cyclo-octa-1,5-diene or NNN′N′-tetramethylethylenediamine] have been prepared by addition of the corresponding neutral ligand to chloroform solutions of [Pd(C6F3H2)2(PhCN)2]. Proton, 19F, and 31P n.m.r. data for all the square-planar palladium(II) complexes have been collected and 31P-{1H} spectra show that they are the cis isomers. The complex [Pd(C6F3H2)2(PhCN)2] reacts with NMe4Cl to give [NMe4]2[Pd2(C6F3H2)4(µ-Cl)2] and treatment of this with the appropriate alkali-metal salt (KBr, NaI, or KSCN) leads to [NMe4]2[Pd2(C6F3H2)4(µ-X)2](X = Br, I, or SCN). The behaviour of the binuclear anions in the solvents acetone and dimethyl sulphoxide has been studied by 19F n.m.r. spectroscopy. The crystal structure of [P(CH2Ph)Ph3]2[(C6F3H2)2Pd(µ-SCN)-(µ-NCS)Pd(C6F3H2)2] has been solved and refined to R= 0.040 based on 3 384 observed reflections, confirming the existence of centrosymmetric binuclear anions where the Pd atoms have square-planar co-ordination [Pd-C 2.02(1) and 1.99(1), Pd–S 2.387(5), and Pd–N 2.07(1)Å].
Somnambulism (1963)

<h3>Introduction</h3> Although sleepwalking is a common nocturnal disturbance of young children, generally regarded as a symptomatic immaturity habit, there is considerable literature in the area of child psychiatry,<sup>5,22,32,44</sup>most of which aims at differentiating somnambulism from night terrors.<sup>23,35</sup>In contrast, few studies have been done on adult somnambulism. This is partly due to the fact that the adult somnambulist is not inclined, encouraged, or forced to seek psychiatric consultation unless he is in the Armed Forces or under indictment for a crime allegedly committed during a somnambulistic state. For these reasons, forensic<sup>5,6,24,41</sup>and military psychiatrists<sup>20,21,35,39,40,42,45</sup>have written most extensively about somnambulism in late adolescence and adulthood, somnambulism in connection with homicide, and also the inherent dangers of military life to the somnambulist. It is well known in the naval service that the sleepwalker risks a
Precision Cosmic-Ray Measurements up to Within a Percent or Two of the Top of the Atmosphere (1936)

Self-recording, constant pressure, argon-filled electroscopes sent into the stratosphere by sounding balloons at San Antonio, Texas, mag. lat. 39\ifmmode^\circ\else\textdegree\fi{}N, yielded accurate readings of cosmicray intensities up to an altitude 98.3 percent of the way to the top of the atmosphere, where the pressure is but 12.9 mm of Hg. The ionization within these electroscopes passes through a definite maximum at 47.6 mm of Hg and falls 22 percent in rising to where the pressure is 12.9 mm of Hg. These results, combined with similar accurate measurements on the variation of cosmic-ray intensities as a function of latitude, both at sea level and at altitudes of 22,000 feet, indicate (1) that atmospheric cosmic-ray ionization is not produced in appreciable amount by incoming protons, and (2) that the Oppenheimer-Bethe-Heitler law of nuclear absorption is not valid for incoming electrons of a few billion $e$-volts of energy.
Energy converting devices based coupled fluidics and ion transport in nanopore systems (2014)

The multiphysical modeling and simulation of hydrodynamic pressure-driven fluidics and ionic transport in nanopore systems is presented. The physical model couples Poisson equation for electrostatics, steady-state Navier-Stokes equation for laminar flow, and steady-state Nernst-Plank equation for ionic motion. The influence of the nanopore geometry and electrical properties on the induced electrical current is quantitatively investigated. Based on our discussion, we explore the potential strategies for further improving the mechanical-to-electrical energy conversion efficiency, which would enhance the performance of nanopore based power generating devices.
Remove Rhodium Catalysts from HNBR Solution (2011)

Rhodium complex is excellent catalyst for nitrile-butadiene rubber homogeneous hydrogenation with difficulties in its recovery. A new extraction method for recovery noble metal catalysts from hydrogenated nitrile-butadiene rubber solution was investigated. Rhodium metal catalysts can be efficiently, easily removed from hydrogenated nitrile-butadiene rubber solution using amine as ligand and hydrogen peroxide as oxidant. The condition of removing noble metal catalysts from hydrogenated nitrile-butadiene rubber solution was carefully studied, including oxidant, reaction temperature, and the concentration of amine. The removal rate of the rhodium catalyst over 96% with the optimal conditions.1H-NMR characterization showed that there was no change in the structure and nitrile group of hydrogenated nitrile-butadiene rubber after rhodium catalysts were removed.
A 5.5 GHz fractional frequency-synthesizer IC (2002)

We report a GaAs-AlGaAs fractional frequency-synthesizer IC with a 5.5 GHz feedback divider, 2 GHz reference divider, 500 MHz phase-frequency detector, 1 ns charge-pump pulses, gain-normalized output current, and 18 pA/sub rms///spl radic/Hz in-band phase noise. The feedback divider allows continuously selectable divide ratios from 12 to 16383, and supports dual-modulus pulse-swallowing fractional synthesis with single-bit control. The reference divider allows continuously selectable divide ratios from 1 to 4095; an optional divide-by-four/five input prescaler extends the divide ratios to 20475. The chip consumes 1 W from +5 V and -5.2 V supplies.
Design of a Lipid Bilayer Electrical Device. Strong Chemical Structure Dependence and Molecular Mechanisms on the Phase Transition-Dependent Electrical Impedance Responses of the Device in Air (1997)

This paper describes the design and fabrication of a lipid film-modified electrical device and the relation between the chemical structure of the lipids and the impedance responses of the device in air. Eight different synthetic poly(ion-complexed) lipids including quaternary ammonium lipids, glutamic acid (Glu)-based lipids with a short or a long methylene spacer chain, and diethanolamine-based quaternary ammonium lipids with a long or a short spacer chain were synthesized. Transparent multibilayer films with crystalline-to-liquid crystalline phase transition were formed, and impedance responses for interdigitated array electrodes coated with cast films of these lipids were examined. Complex plane plot analyses together with quartz crystal microbalance and FTIR experiments have revealed molecular mechanisms for the unique impedance responses which could be classified as the following three types. Type I is the phase transition-dependent impedance responses, where the impedance changes dramatically near the phase transition temperatures of the lipid bilayer films on the electrodes. The change is derived from the increase in the mobility of the ion-conducting carrier (protons) coupled with the phase transition. The lipid devices coated with cast films of quaternary ammonium lipids with no spacer or a short spacer belong to this type. Type II is a device coated with a cast film of a diethanolamine-based quaternary ammonium lipid with a long spacer. Tc-dependent impedance response similar to that in type I is observed, but the molecular mechanism of the response is different. Type III exhibits a phase transition-independent impedance response. Electrical devices using Glu-based primary ammonium lipids and a Glu-based quaternary ammonium lipid with a long spacer as electrode modifiers give this type of response. Conformational mobility of the hydrophilic head group moieties of these lipid bilayers is maintained rigid through hydrogen bonding even at temperatures higher than the phase transition which results in this response.
SYNTHESIS OF 2′-DEOXY-2′-FLUORO- 1-β-<scp>d</scp>-ARABINOFURANOSYL URACIL DERIVATIVES: A METHOD SUITABLE FOR PREPARATION OF [<sup>18</sup>F]-LABELED NUCLEOSIDES (2002)

ABSTRACT N-glycosylation of 2,4-bis-O-(trimethylsilyl)-pyrimidine bases with 2-deoxy-2-fluoro-3,5-di-O-benzoyl-1-(Br, OBz)-α-d-arabinose derivatives are reported. 1-Bromo-arabinose provides high yield and a favorable anomeric ratio (β/α) of pyrimidine nucleoside in either MeCN or CH2Cl‒CH2Cl. This method should be suitable for the synthesis of 2′-deoxy-2′-[18F]fluoro-1-β-d-arabinofuranosyluracil derivatives.
