Electrical Resistivity Surface for FeO‐Fe <sub>2</sub> O <sub>3</sub> ‐P <sub>2</sub> O <sub>5</sub> Glasses (1975)

The dc electrical properties and microstructure of x (FeO‐Fe 2 O 3 )‐(100 – x )P 2 O 5 glasses were investigated up to a maximum of x = 75 mol%. Results indicate that, in general, the minimum resistivity of the glass does not occur at equal Fe 2+] and Fe 3+] concentrations, although for the special case where x = 55 mol% the minimum does occur at Fe 2+] /Fe total = 0.5, as reported by other investigators. Evidence presented shows that the position of the minimum resistivity is a function of total iron content. The minimum shifts to glasses richer in Fe 2+] at higher total iron concentrations.

The good response after radiation therapy group in the DLD-1 colon cancer xenograft nude mouse model exhibited a higher pretreatment K(trans) and showed an early reduction in K(trans), demonstrating a more homogenous distribution.
Whats in a Satellite Albedo Product? (2006)

Land surface albedo is one of the key drivers of the Earth's terrestrial surface energy budget. Surface Albedo products derived from satellite observations are increasingly being used as input to climate modelling. The derivation of surface albedo is a multidimensional challenge, whereas the sensor-specific calculation relies not only on the configuration of the observation, but also on angular models for inter- and extrapolation of the reflectance quantities to illumination and view angles not sampled by the satellite observations, as well as spectral conversion algorithms. While either combining albedo data from different sources or comparing studies relying on different albedo products, the above factors contribute to a bias and consequently to additional uncertainties. It is thus important to provide all relevant information of the albedo product generation, helping users to reduce uncertainties and enabling to link the different types of albedo in a physically consistent way. We are presenting a standardized description, exemplified using a selection of operational satellite products (i.e., MODIS, MISR). This effort will be continued through adding surface albedo products from instruments such as MERIS, POLDER, VEGETATION, and geostationary satellites.
Soft-Switching Characterization of Medium-Voltage IGBT Power Modules and Press-Pack Diodes in a 1 kHz Mega-Watt dc/dc Resonant Converter (2018)

6.5kV IGBT power modules and line frequency press-pack diodes are proposed for a new mega-watt, medium voltage, resonant converter intended for DC wind turbines. The challenge of characterizing losses in softswitching semiconductors - without building the full circuit - is overcome by a proposed test circuit and procedure that minimizes cost and complexity, yet subjects the device under test to similar use as in the target application. The paper describes the test method, and results obtained with it.
Reconfigurable anisotropy and functional transformations with<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mi>VO</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:math>-based metamaterial electric circuits (2015)

We demonstrate an innovative multifunctional artificial material that combines exotic metamaterial properties and the environmentally responsive nature of phase-change media. The tunable metamaterial is designed with the aid of two interwoven coordinate-transformation equations and implemented with a network of thin-film resistors and vanadium dioxide (${\mathrm{VO}}_{2}$). The strong temperature dependence of ${\mathrm{VO}}_{2}$ electrical conductivity results in a significant modification of the resistor network behavior, and we provide experimental evidence for a reconfigurable metamaterial electric circuit that not only mimics a continuous medium, but is also capable of responding to thermal stimulation through dynamic variation of its spatial anisotropy. Upon external temperature change, the overall effective functionality of the material switches between a ``truncated cloak'' and a ``concentrator'' for electric currents. Possible applications may include adaptive matching resistor networks, multifunctional electronic devices, and equivalent artificial materials in the magnetic domain. Additionally, the proposed technology could also be relevant for thermal management of integrated circuits.

Accelerometer‐Derived Time Intervals during Various Pacing Modes in Patients with Biventricular Pacemakers: Comparison with Normals (2007)

Shortening of the IVCT measured by an accelerometer is a consistent time interval change due to biventricular pacing that probably reflects more rapid acceleration of left ventricular ejection. The accelerometer may be useful to assess immediate efficacy of biventricular pacing during device implantation and optimize programmable time intervals such as AV and interventricular (VV) delays.
Toxoplasma gondii catalase: are there peroxisomes in Toxoplasma? (2000)

The intracellular protozoan parasite Toxoplasma gondii, like all members of the phylum Apicomplexa, is known to possess many organelles: in addition to mitochondria and the compartments of the secretory pathway, there is a reduced chloroplast (the apicoplast) and the phylum-specific components of the apical complex: dense granules, micronemes and rhoptries. Conspicuously missing so far are microbodies, organelles that can be found in nearly all eukaryotic organisms. Microbodies show a large variation with regard to their size, number and contents, depending on the organism and cell type. One marker enzyme of this single membrane-bound organelle is catalase, which is responsible for the degradation of hydrogen peroxide to water and oxygen. The EST project in T. gondii revealed the existence of two overlapping clones which showed similarity with catalase, and these were used to clone the corresponding gene. The predicted sequence of T. gondii catalase has -AKM at the C terminus, which falls within the consensus of the PTS1 peroxisomal targeting signal. Southern blot analysis confirmed the presence of a single copy gene. Northern and western blot analyses showed that the catalase gene is transcribed and translated. Immunofluorescence assays using an antibody raised against a catalase peptide identified a distinct structure towards the apical end, but other catalase-specific antibodies failed to confirm this localisation. Cell fractionations indicated that the majority of the enzyme was in the cytosol. The fusion of the C-terminal twelve amino acids, including AKM, or the canonical peroxisomal targeting signal, -SKL, to GFP resulted in predominantly cytosolic localization in T. gondii. There was therefore no evidence for membrane-bound peroxisomes in Toxoplasma.

Speech‐induced changes in corticospinal excitability (1996)

The aim of the experiments was to investigate the effects of speech on the excitability of corticospinal pathways to human hand muscles. Single transcranial magnetic stimuli were given randomly over the hand area of either the left or right motor cortex of 10 right-handed and 3 left-handed normal volunteers. Electromyographic responses were recorded in the relaxed first dorsal interosseous muscle while the subjects (a) read aloud a piece of text, (b) read silently, (c) spoke spontaneously, or (d) made sounds without speaking. The only consistent effect across subjects occurred during task a, which significantly increased the size of responses evoked in the dominant hand of all subjects, but had either no effect (8 subjects) or a smaller effect in the nondominant hand. Tasks b and d had no reliable effect, whereas task c tended to increase response size in both hands. Control measurements suggest that the effects in task a were caused by changes in cortical rather than spinal excitability. This is the first demonstration of lateralized speech effects on the excitability of cortical arm areas. The results provide a useful adjunct to other tests of cerebral dominance, using only single- rather than repetitive-pulse cortical stimulation.
Delayed Sleep Phase Syndrome (1981)

We describe a new syndrome called "delayed sleep phase insomnia." Thirty of 450 patients seen for a primary insomniac complaint had the following characteristics: (1) chronic inability to fall asleep at a desired clock time; (2) when not on a strict schedule, the patients have a normal sleep pattern and after a sleep of normal length awaken spontaneously and feel refreshed; and (3) a long history of unsuccessful attempts to treat the problem. These patients were younger than the general insomniac population and as a group did not have a specific psychiatric disorder. Six patients' histories are described in detail, including the successful nonpharmacological chronotherapy regimen (resetting the patients' biological clock by progressive phase delay). Delayed sleep phase insomnia is proposed to be a disorder of the circadian sleep-wake rhythm in which the "advance" portion of the phase response curve is small.

Cytotoxicity of human serum for Leishmania donovani amastigotes: antibody facilitation of alternate complement pathway-mediated killing (1985)

Mechanisms that mediate recovery from leishmanial infection have not been fully characterized but are generally believed to involve interactions between T lymphocytes and macrophages. A major role for serum-mediated effector mechanisms in the protection of humans from reinfection with Leishmania, however, has not been ruled out. In this report, amastigotes of L. donovani were incubated with dilutions of serum from normal subjects and from patients with kala-azar. Normal serum was cytotoxic for parasites at a dilution of greater than or equal to 1:20. Cytotoxicity did not occur in the presence of EDTA, was abolished by heating serum to 56 degrees C for 30 min, and was not diminished by prior adsorption of normal serum with parasites at 0 degree C. Killing proceeded normally in the presence of magnesium-ethylene glycol-bis(beta-aminoethyl ether)-N, N-tetraacetic acid, however, and was fully effected by C2-deficient serum. These studies indicated that killing of amastigotes, unlike that of promastigotes, was mediated via the alternate pathway of serum complement. In further studies, cytotoxicity of normal serum was enhanced three- to fivefold by factors in patient serum. This enhanced cytotoxicity also proceeded via the alternate complement pathway. Factors that enhanced cytotoxicity were characterized as parasite-specific immunoglobulin G: they eluted with immunoglobulin G on column chromatography, were adsorbed by immobilized staphylococcal protein A, and were not removed from the parasite surface by extensive washing. Thus, infection of individuals with L. donovani resulted in the production of a new, qualitatively and quantitatively distinct immune mechanism directed against the amastigote form of the parasite, namely, antibody-directed, alternate complement pathway-mediated cytotoxicity. These results provide a mechanistic framework for a role of humoral factors in human resistance to reinfection with L. donovani.

Evidence for a little ice age and recent warming from a borehole temperature data inversion procedure (2004)

In this article, we apply our analytical theory, published earlier in this journal, to obtain information on the earth surface temperature history from some borehole temperature data. Compared to the results of the five different methods applied to the same temperature data, our method seems to be easier, assumption-free, and yields internally consistent results. The results suggest a cooling a few centuries ago, followed by a continuing warming up to these days, in agreement with a little ice age scenario.
Experimental investigation of muon-catalyzed t + t fusion (2009)

The muon-catalyzed fusion (μCF) process in tritium was studied by the μCF collaboration on the muon beam of the JINR Phasotron. The measurements were carried out with a liquid tritium target at the temperature 22 K and density approximately 1.25 of the liquid hydrogen density (LHD). Parameters of the μCF cycle were determined: the ttμ muonic molecule formation rate λ ttμ = 2.84(0.32) μs−1, the ttμ fusion reaction rate λ f = 15.6(2.0) μs−1, and the probability of muon sticking to helium ω tt = 13.9(1.5)%. The results agree with those obtained earlier by other groups, but better accuracy was achieved due to our unique experimental method.

An AI Approach to Ground Station Autonomy for Deep Space Communications (1998)

This paper describes an architecture for an autonomous deep space tracking station (DS-T). The architecture targets fully automated routine operations encompassing scheduling and resource allocation, antenna and receiver predict generation. track procedure generation from service requests, and closed loop control and error recovery for the station subsystems. This architecture has been validated by the construction of a prototype DS-T station, which has performed a series of demonstrations of autonomous ground station control for downlink services with NASA's Mars Global Surveyor (MGS).
Achieving Net Feedback Gain in the Butterfly Network with a Full-Duplex Bidirectional Relay (2012)

A symmetric butterfly network (BFN) with a full-duplex relay operating in a bi-directional fashion for feedback is considered. This network is relevant for a variety of wireless networks, including cellular systems dealing with cell-edge users. Upper bounds on the capacity region of the general memoryless BFN with feedback are derived based on cut-set and cooperation arguments and then specialized to the linear deterministic BFN with really-source feedback. It is shown that the upper bounds are achievable using combinations of the compute-forward strategy and the classical decode-and-forward strategy, thus fully characterizing the capacity region. It is shown that net rate gains are possible in certain parameter regimes.
A Proposal of Knowledge Acquisition Support System with a Presentation of Inferred Modifications and Its Application to Decision of Priorities of Assembling Products (1993)

順序構造モデルによるファジィ推論は、各入力ごとに推論規則を記述し、推論規則間の順序関係を規定することで推論結果の調整を行う手法であり、人間の経験的推論規則との対応がとりやすいという特徴を持つ。この推論により生産現場における作業着手手順決定問題を解くには、各製品の完成予定日、部品欠品数、所要作業時間等の種々の要因に関する推論規則に対して生産管理のベテランが持つ重視度を獲得しなければならない。しかし、生産管理者がこれらの重視度を明確に意識しているとは限らないため、重視度の抽出は手数の要る作業となっている。本論文では、作業着手手順決定問題において、生産管理者の持つ上記重視度を獲得すべき知識と見なし、新たに PRIMITIVE 曲線を提案し、この曲線をもとに重視度の修正案をファジィ推論により求める知識獲得支援システムを提案する。本手法の有効性を確認するため、生産現場の具体例をもとに、仮想的に重視度獲得の実験を行う。
Er luminescence centers in GaAs grown by migration-enhanced epitaxy (1993)

Er-doped GaAs has been grown by migration-enhanced epitaxy. The samples were grown at 300, 400, and 500 °C. Secondary ion mass spectroscopy measurements showed that the Er concentration in the grown epitaxial layer does not depend on the growth temperature between 300 and 500 °C. All samples showed luminescence due to the Er intra-4f-shell transition from the 4I13/2 excited state to the 4I15/2 ground state, but the spectra change drastically when the growth temperature is increased from 300 °C to 400 or 500 °C. The photoluminescence spectra of the samples grown above 400 °C are simpler than that of the sample grown at 300 °C. The spectrum of the sample grown at 300 °C became broad after annealing, whereas the spectra of the samples grown at 400 °C and above showed only changes in the relative intensity of the main luminescence lines. Some thermally stable Er luminescence centers seem to be preferentially formed at 400 and 500 °C.
Effects of the Androgen Antagonist Flutamide and the Serotonin Reuptake Inhibitor Citalopram in Bulimia Nervosa (2005)

Prompted by previous studies suggesting that bulimia nervosa in women may be associated with elevated serum levels of testosterone, we have evaluated the possible effect of androgen antagonism in this condition. To this end, women meeting the DSM-IV criteria of bulimia nervosa, purging type, were treated in a one-center study with the androgen receptor antagonist flutamide (n = 9), the serotonin reuptake inhibitor citalopram (n = 15), flutamide plus citalopram (n = 10), or placebo (n = 12) for 3 months using a double-blind design. Self-rated global assessment of symptom intensity suggests all active treatments to be superior to placebo. The reduction in binge eating compared with baseline was statistically significant in both groups given flutamide but not in the groups given citalopram only or placebo. A moderate and reversible increase in serum transaminase levels led to discontinuation in two subjects in the flutamide group. It is concluded that blockade of androgen receptors may reduce some of the symptoms of bulimia nervosa in women.
Fibrin-derived vasoactive peptides release histamine. (1983)

Two fibrin-derived peptides. Ala-Arg-Pro-Ala-Lys and Ser-Gln-Leu-Gln-Lys-Val-Pro-Pro-Glu-Trp-Lys, increase microvascular permeability in rat skin. In the present investigation it is shown that they release histamine from rat mast cells and that their effect on microvascular permeability can be inhibited by previous histamine depletion of the skin or treatment with an antihistamine, the H1-blocker mepyramine maleate. It is concluded that histamine release contributes to the permeability-increasing effect of these peptides as well as of the structurally similar peptides bradykinin, substance P and neurotensin.
Ligand Dynamics of Drug-Loaded Microporous Zirconium Terephthalates-Based Metal–Organic Frameworks: Impact of the Nature and Concentration of the Guest (2014)

Impact of encapsulation of model drug molecules bearing different chemical features (caffeine or ibuprofen) over the molecular dynamics of a series of functionalized zirconium terephthalate UiO-66(Zr) type metal–organic frameworks was investigated by dielectric relaxation spectroscopy. If the rotational motions of the ligands are more significantly perturbed by the guest dimension and loading rather than their chemical features, the dynamics strongly depends on the nature of the functional group of the terephthalate ligand, as shown typically when comparing the amino- or bromo-functionalized forms. While for UiO-66(Zr)–NH2 the dynamics of the ligands is partially enhanced in the presence of both drugs, the scenario differs for the bromo form which shows a slower dynamics. This is discussed from a qualitative analysis of the global interactions within these solids as a matter of the ligand/framework and ligand/guest molecules pairs of interactions.
