We have used the spin-precession technique to measure the ${\ensuremath{\Sigma}}^{\ensuremath{-}}$ magnetic moment (${\ensuremath{\mu}}_{\ensuremath{\Sigma}}$). A ${\ensuremath{\Sigma}}^{\ensuremath{-}}$ beam with a polarization of 22% was produced by a 400-GeV proton beam striking a Cu target at nominal production angles of \ifmmode\pm\else\textpm\fi{}3 mrad. We simultaneously recorded 21 000 ${\ensuremath{\Sigma}}^{\ensuremath{-}}\ensuremath{\rightarrow}n{e}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ decays and 650 000 ${\ensuremath{\Sigma}}^{\ensuremath{-}}\ensuremath{\rightarrow}n{\ensuremath{\pi}}^{\ensuremath{-}}$ decays at ${\ensuremath{\Sigma}}^{\ensuremath{-}}$ beam momenta of 253 and 308 GeV/c. We find ${\ensuremath{\mu}}_{\ensuremath{\Sigma}}=\ensuremath{-}1.166\ifmmode\pm\else\textpm\fi{}0.014\ifmmode\pm\else\textpm\fi{}0.010$ nuclear magnetons, where the quoted errors are statistical and systematic, respectively.

Electrohydrodynamic Ion Source (1969)

An electrohydrodynamic (EHD) technique is used to generate ions from liquid metals. Liquid metal is fed to the tip of a capillary needle emitter with a voltage difference applied between the emitter and an extractor electrode to produce an intense electric field at the liquid surface. Electrostatic forces overcome surface tension forces to produce ions by field emission. When using liquid cesium, time-of-flight mass analysis showed the ion current to be primarily Cs+ with a small percentage of Cs2+ and Cs3+. Electron currents of over 1 mA have been produced by operating the emitter at 2 kV negative. Besides cesium, alkali ion beams have been generated using NaK/cesium alloy and sodium. Calculations show that liquid metals of low work functions appear more suitable for production of atomic ions while higher work functions metals may produce multiatomic ions and charged droplets in addition to atomic ions.
Efficiency of OPU-IVEP-ET of fresh and vitrified embryos in buffaloes. (2013)

The present study aims to report ovum pickup (OPU), in vitro embryo production (IVEP) and embryo transfer (ET) outcomes of fresh and vitrified buffalo embryos. For this purpose, 36 buffalo donors were submitted to 11 OPU sessions (n = 201). A total of 998 oocytes (5.0 +/- 0.5/donor/session) and 584 viable oocytes (2.9 +/- 0.3/donor/session) were recovered. Viable oocytes (grades 1, 2 and 3) were subjected to IVM, IVF (D0) and IVC. On D2, 54.5% of cleavage rate was obtained. Embryo yield on D7 was 44.9% (grade 1: 229 embryos, grade 2: 5 embryos and grade 3: 28 embryos). From this total, 115 fresh (grades 1 to 3) and 70 vitrified embryos (only grade 1) were transferred into recipients previously synchronized with fixed time embryo transfer (FTET) protocol. Vitrification was performed using the cryotop method. Pregnancy diagnosis in fresh and in vitrified groups were, respectively: 43.5% (50/115) and 37.1% (26/70) on 30 days after embryo transfer, and 41.7% (48/115) and 31.4% (22/70) on 60 days after embryo transfer. In conclusion, our results demonstrate the possibilities for commercial use of the techniques of OPU, IVEP and ET of fresh and vitrified embryos in buffaloes.
Fast Formation of Conductive Material by Simultaneous Chemical Process for Infilling Through-Silicon Via (2012)

It is necessary to develop a fast and inexpensive fabrication process of vertical electric wiring by through-silicon via (TSV) technology for advanced three-dimensional semiconductor devices. In this research, a fast-forming conductive composite was successfully developed by simultaneous deposition of conductive organic polymer (polypyrrole) and metal (silver) from the liquid phase, accelerated by photoirradiation. The growth rate of the composite was 38 nm·s-1, which is more than 10 times higher than that of copper by conventional plating. The electric conductivity of the composite was 2.1×104 Ω-1·cm-1, which is on the same level as general metal conductors. In addition, the effects of reaction conditions on the growth rate and the conductivity of the composites were revealed. From these results, the infilling time of the TSV was expected to shorten from the present 2–10 h to 5–10 m.

Studies on the cytotoxic effect of Newcastle disease virus (NDV) on Ehrlich ascites tumor cells. II. The mechanism and significance of in vitro recovery from the effect of NDV. (1957)

Summary The findings of Moore and co-workers (1, 2) were confirmed in that Ehrlich ascites tumor cells recovered the capacity to propagate in mice when suspensions of NDV and tumor cells were held at 21–23°C for 4 hr in vitro . It was demonstrated that “recovery” of Ehrlich ascites tumor cells from the action of NDV occurred only when conditions existed which permitted elution of virus from tumor cells. At 37°C, recovery was prevented by the establishment of a stable union between virus and tumor cell. The union involved loss of the ability of virus-cell complexes to combine with specific viral antibody. This loss took place within 10 min after the virus cell mixture was brought to 37°C. These data suggested that the killing of tumor cells by NDV did not occur solely as a result of the reaction of virus with the tumor cell surface.
High-Mobility Group Box 1-Induced Complement Activation Causes Sterile Inflammation (2018)

High-mobility group box 1 (HMGB1), a well-known danger-associated molecular pattern molecule, acts as a pro-inflammatory molecule when secreted by activated immune cells or released after necrotic cell damage. HMGB1 binds to immunogenic bacterial components and augments septic inflammation. In this study, we show how HMGB1 mediates complement activation, promoting sterile inflammation. We show that HMGB1 activates the classical pathway of complement system in an antibody-independent manner after binding to C1q. The C3a complement activation product in human plasma and C5b-9 membrane attack complexes on cell membrane surface are detected after the addition of HMGB1. In an acetaminophen (APAP)-induced hepatotoxicity model, APAP injection reduced HMGB1 levels and elevated C3 levels in C1q-deficient mouse serum samples, compared to that in wild-type (WT) mice. APAP-induced C3 consumption was inhibited by sRAGE treatment in WT mice. Moreover, in a mouse model of brain ischemia-reperfusion injury based on middle cerebral arterial occlusion, C5b-9 complexes were deposited on vessels where HMGB1 was accumulated, an effect that was suppressed upon HMGB1 neutralization. We propose that the HMGB1 released after cell necrosis and in ischemic condition can trigger the classical pathway of complement activation to exacerbate sterile inflammation.
Detective quantum efficiency for photon-counting hybrid pixel detectors in the tender X-ray domain: application to Medipix3RX (2015)

Synchrotron-radiation-based X-ray imaging techniques using tender X-rays are facing a growing demand, in particular to probe the K absorption edges of low-Z elements. Here, a mathematical model has been developed for estimating the detective quantum efficiency (DQE) at zero spatial frequency in the tender X-ray energy range for photon-counting detectors by taking into account the influence of electronic noise. The experiments were carried out with a Medipix3RX ASIC bump-bonded to a 300 µm silicon sensor at the Soft X-ray Spectroscopy beamline (D04A-SXS) of the Brazilian Synchrotron Light Laboratory (LNLS, Campinas, Brazil). The results show that Medipix3RX can be used to develop new imaging modalities in the tender X-ray range for energies down to 2 keV. The efficiency and optimal DQE depend on the energy and flux of the photons. The optimal DQE values were found in the 7.9-8.6 keV photon energy range. The DQE deterioration for higher energies due to the lower absorption efficiency of the sensor and for lower energies due to the electronic noise has been quantified. The DQE for 3 keV photons and 1 × 10(4) photons pixel(-1) s(-1) is similar to that obtained with 19 keV photons. Based on our model, the use of Medipix3RX could be extended down to 2 keV which is crucial for coming applications in imaging techniques at modern synchrotron sources.
Über α‐Halogenäther, XVII. Umsetzung von Brenzcatechin‐dichlormethylenäther mit <i>O</i>‐ und <i>N</i>‐funktionellen Verbindungen (1964)

Abstract Brenzcatechindichlormethylenäther (I) reagiert mit Alkoholen je nach Reaktionsbedingungen zu 2.2‐Dialkoxy‐1.3‐benzodioxolen oder Alkylchloriden; Carbonsäuren bzw. Carbonsäureanhydride geben mit I Carbonsäurechloride, Äthylenoxyd wird in Dichloräthan übergeführt. Die Struktur eines bei alkalischer Hydrolyse von I entstehenden Produktes wurde aufgeklärt. Carbonylverbindungen tauschen den Sauerstoff gegen zwei Halogenatome aus, ebenso setzen sich Formiate zu Dichloräthern um. Säureamide werden zu Nitrilen dehydratisiert, disubstituierte Säureamide geben entweder Säureamiddichloride oder werden gespalten in Nitril und Alkylchlorid. Mit primären Aminen erhält man je nach Bedingungen Benzdioxolonimide oder trisubstituierte Guanidine. Sekundäre Amine geben Acetale tetrasubstituierter Harnstoffe. Bei tertiären Aminen wurden Entalkylierungen beobachtet.

<scp>AAIRS</scp> Score Overview: The Acute Asthma Intensity Research Score (2015)

Pediatric acute asthma exacerbations are responsible for 640,000 emergency department (ED) visits each year and are the most frequent reason for childhood hospitalization in the United States.1 Expert panel guidelines recommend that treatment and hospitalization decisions be made based on assessment of severity and response to treatment. However, these guidelines specify severity assessment that includes spirometry for peak expiratory flow measurement (FEV1), measures that are generally unavailable or difficult for pediatric patients to perform during exacerbations.2-4 The Acute Asthma Intensity Research Score (AAIRS) is a 17-point (0 to 16, with 16 most severe) bedside severity score that uses readily evaluated physical signs (Figure 1) and that has been validated against the criterion standard %-predicted FEV1.5, 6 We are not aware of training videos published in the peer review literature for acute asthma severity scores. The accompanying video (video clip S1, available at: https://vimeo.com/122443037) follows the course of a young child with a moderately severe asthma exacerbation over several hours of ED care to demonstrate the seven physical signs comprising the AAIRS and how they are to be evaluated for AAIRS scoring. The protocol under which the AAIRS was developed was approved by our institutional review board, and development of the training video was a quality improvement initiative requested by our clinical leadership.

Immunology: Diversity of the blocking effects of antisperm antibodies on fertilization in human and mouse (1996)

The blocking effects of complement-dependent sperm immobilizing antibodies in the sera of infertile women and monoclonal antisperm antibodies against humans and mice on fertilization were investigated. The hemizona assay (HZA) and sperm penetration assay (SPA) were used to study the inhibitory effects of sera from 22 infertile patients positive for sperm immobilizing antibodies. Use of these tests allowed us to differentiate whether the antibody blocked sperm-zona pellucida tight binding and/or sperm penetration into the ooplasm. The zona pellucida penetration assay (ZPA) was also used to study the effects of four monoclonal antibodies (mAbs) on human sperm penetration into the zona pellucida. Seven mAbs against murine spermatozoa were tested for their inhibitory effects on in-vitro fertilization (IVF) and HZA in mice. Of 22 patient sera with sperm immobilizing antibodies, 21 (95.5%) inhibited HZA attachment and penetration, whereas this did not occur in any of 13 patient sera without these antibodies. However, 19 of 22 (86.4%) patient sera with sperm immobilizing antibodies and eight of 13 (61.5%) patient sera without these antibodies inhibited the SPA. Two (2C6, 1G12) of four mAbs against human spermatozoa showed strong inhibitory effects in all the assays (HZA, ZPA and SPA). One mAb (3B10) did not inhibit HZA but blocked ZPA and SPA. Another mAb (H6-3C4) seemed to have no inhibitory effects on fertilization. Two (Vx 5 and Vx 8) of seven mAbs against murine spermatozoa inhibited IVF in mice but did not block mouse HZA. These findings suggest that antisperm antibodies block fertilization at specific stages. Some of them may inhibit sperm capacitation and thus prevent all processes of fertilization that follow. Some other antibodies may not affect capacitation and sperm binding to zona pellucida but inhibit the acrosome reaction, followed by the blocking of sperm penetration through zona pellucida and ooplasm.

A 389MIPS application processor for 3G cellular phones is implemented in a 0.13/spl mu/m dual-V, process. This dual-issue superscalar CPU with DSP runs at 216MHz at 1.2V and provides a resume-standby mode with a quick recovery feature using data retention of memory. The leakage current is estimated to be 98/spl mu/A when the power supply is internally cut off.
Kinks in the presence of rapidly varying perturbations (1994)

The dynamics of sine-Gordon kinks in the presence of rapidly varying periodic perturbations of different physical origins is described analytically and numerically. The analytical approach is based on asymptotic expansions, and it allows one to derive, in a rigorous way, an effective nonlinear equation for the slowly varying field component in any order of the asymptotic procedure as expansions in the small parameter ${\mathrm{\ensuremath{\omega}}}^{\mathrm{\ensuremath{-}}1}$, \ensuremath{\omega} being the frequency of the rapidly varying ac driving force. Three physically important examples of such a dynamics, i.e., kinks driven by a direct or parametric ac force, and kinks on a rotating and oscillating background, are analyzed in detail. It is shown that in the main order of the asymptotic procedure the effective equation for the slowly varying field component is a renormalized sine-Gordon equation in the case of the direct driving force or rotating (but phase locked to an external ac force) background, and it is the double sine-Gordon equation for the parametric driving force. The properties of the kinks described by the renormalized nonlinear equations are analyzed, and it is demonstrated analytically and numerically which kinds of physical phenomena may be expected in dealing with the renormalized, rather than the unrenormalized, nonlinear dynamics. In particular, we predict several qualitatively new effects which include, e.g., the perturbation-induced internal oscillations of the 2\ensuremath{\pi} kink in a parametrically driven sine-Gordon model, and the generation of kink motion by a pure ac driving force on a rotating background.
Staurosporine‐induced apoptosis of immortalized mouse proximal tubule cells is modulated by bcl‐2 expression level (1997)

Mouse terminal proximal tubule (S3)cells treated with staurosporine (STS) underwent morphological and biochemical changes characteristic of apoptosis. Treatment of S3 cells with STS, H-7, PMA, herbimycin A or genistein caused DNA fragmentation. STS inhibited the activity of protein kinase C but not of cdc-2 kinase in S3 cells. No change in cell cycle distribution was observed in S3 cells treated with STS. However, treatment of S3 cells with STS resulted in a decrease in the level of bcl-2 mRNA expression in the cells. Overexpression of bcl-2 inhibited the degree of STS-induced apoptosis of S3 cells. In conclusion, STS induces apoptosis of mouse S3 cells via inhibition of various protein kinases including protein kinase C, and the apoptosis is modulated by the bcl-2 expression level.
Controlled polymer synthesis in homogeneous and heterogeneous processes (2001)

Research in polymer synthesis can be oriented toward method or structure. This review is intended to document both approaches. Recent examples from our own work as well as future prospectives will be presented. A general concern is to work out the impact from organic and supramolecular chemistry. Examples of method oriented work are (i) a unique polycondensation via carbon sulfur-bond formation providing hybrid structures of, e.g., polyphenylenesulfide and polyaniline; (ii) a triazoline additive establishing a novel self-regulation process in controlled radical polymerization; (iii) a metallocene catalyzed polyolefin synthesis which is performed by using “smart”, reversibly cross-linked polymer resins as support; and (iv) hydrogen-bonded aggregates suggesting new emulsifiers for emulsion polymerization thus leading to functional nanoparticles. Examples of structure oriented work are (i) rod-coil block copolymers (1D case) as a “covalently bound combination” of rigid and flexible segments whereby a key synthetic concern is the chemical modification and quantitative end-functionalization of polyphenylene chains; (ii) discs (2D case) as molecularly defined graphite subunits which are obtained via a remarkably mild intramolecular cyclodehydrogenation; and (iii) dendrimers (3D case) as shape-persistent nanoparticles whose high degree of structural precision results from a new cycloaddition-deprotection protocol.

Structural and Morphological Characterization of the PP-0559 Kaolinite from the Brazilian Amazon Region (2002)

We report a structural and morphological characterization of the natural kaolinite PP-0559, from the Brazilian Amazon region, with the aim to contribute to the understanding of this clay mineral in environmental redox reactions. The triclinic structure was confirmed by transmission electron microscopy and electron diffraction studies. It exhibits oriented crystals, with diameters between 0.2 and 2 mum and about 50 nm of thickness. The anisotropic crystals after orientation were studied by electron paramagnetic resonance as a function of the applied magnetic field. The main EPR absorption lines of the substitutional Fe+3 impurity and radiation induced paramagnetic centers were studied as possible oxidizing centers of kaolinite.
MOTORCYCLE BRAKING TEST PROCEDURES AND PERFORMANCE (1980)

Motorcycle braking test procedures and results are presented from an experiment made to quantify motorcycle accident avoidance qualities. Both straight line and combined cornering and braking maneuvers were used. Test conditions included various initial speeds, turn radii, surface skid numbers, and levels of braking effort for two instrumented motorcycles. The effect of braking on transient yaw response in turns is demonstrated. Overall, the results show that repeatable safety related response and performance measures can be obtained using the prescribed procedures with expert test riders.
Automatic test generation using genetically-engineered distinguishing sequences (2002)

A fault-oriented sequential circuit test generator is described in which various types of distinguishing sequences are derived, both statically and dynamically, to aid the test generation process. A two-phase algorithm is used during test generation. The first phase activates the target fault, and the second phase propagates the fault effects (FE's) from the flip-flops with assistance from the distinguishing sequences. This strategy improves the propagation of FE's to the primary outputs, and the overall fault coverage is greatly increased. In our new test generator, DIGATE, genetic algorithms are used to derive both activating and distinguishing sequences during test generation. Our results show very high fault coverages for the ISCAS89 sequential benchmark circuits and several synthesized circuits.
