Large Deflection Electrostatic Spiral Actuator with Twisted-beams (2006)

In this paper, we propose a large-deflection electrostatic spiral-actuator with novel twisted-beams fabricated by surface micromachining. The stress-induced or bimetal-like actuators have merits of simple structure and fabrication steps with relatively large stroke. The novel stress-induced actuator presented here is composed of “twisted-beams", which have not only out-of-plane curvature but also rotation along its longitudinal direction. When the twisted-beams are used as components of a spiral actuator, the total stroke of the actuator becomes a sum of each deflection of the beams, and the stroke is much larger than conventional stressinduced spiral actuators. The experimental results of the spiral actuator show the maximum deflection of about 750 μm, which is extremely large for stress-induced-actuators.
Approaches to the Design of Semisynthetic Metal‐Dependent Catalytic Antibodies (2007)

The binding site of the Fab fragment of antibody MOPC315 was chemically modified with cyclam (1,4,8,11-tetraazacyclotetradecane) and 1,10-phenanthroline. In the presence of the metal ions cobalt(II), copper(II), gallium(III), iron(II), nickel(II), zinc(II), these semisynthetic antibodies did not catalyse the hydrolysis of amides or phosphate ester substrates, or the oxidation of a 1-hydroxy-2-alkene or of 3,4-dihydrobenzamide substrates. Hydrolysis of a coumarin ester substrate was catalysed by the Fab derivatized with a cyclam moiety with a kcat of 0.063 min-1 and Km of 11.7 microM; the presence of metal ions was not required for catalysis.

Monoclonal Antibodies as Probes for the Molecular Structure and Biological Function of Melanoma-Associated Antigens (1985)

A considerable amount of data that accumulated during the last two decades suggested that antigenic changes on the cell surface often accompany neoplastic transformation. This information has led to attempts by a large number of investigators to identify and characterize antigens associated with human tumor cells to gain a more basic understanding of malignant transformation and to develop new immunologic approaches to the diagnosis, prognosis, and therapy of cancer.
Design of an MRI compatible robot for finger rehabilitation (2012)

Studying the brain's recovery process after a stroke during the rehabilitation therapy (ReT) can help to provide important information leading to new rehabilitation treatment and also may help physiotherapists to tailor an optimized training plan for each patient. However, there are few devices that could be used as daily training rehabilitation tool and also can be used for studying the brain activity during ReT. Therefore, in our research, we developed an MRI compatible robot for finger rehabilitation, which possesses the required functions both. The mechanics of this robot were designed to be adjustable to different persons' finger phalanges, and also the gap between one finger to another can be easily changed. By using an ultrasonic motor as its actuator, the device has been designed to be portable, with a high torque output. It enables the client to do extension and flexion rehabilitation exercises in two degrees of freedom (DOF) for each finger. Finally, experiments have been carried out to evaluate the performance of the device.
Development Of Microstructure In Thin Films (1988)

We have modelled the microstructures that result from grain nucleation and growth-to-impingement in two dimensions, using various nucleation and growth conditions. Nucleation conditions include simultaneous nucleation at a fixed number of sites, continuous nucleation at a constant rate per unit of untransformed area, cases in which the nucleation rate declines with time, and cases in which nucleation is excluded in a zone surrounding each pre-existing grain. The growth rate for each grain is taken to be a simple function of the grain radius, either increasing with radius, decreasing with radius, or remaining constant. These different conditions result in markedly different structures, with different geometric and topological properties. We have also modelled the effect of grain boundary migration and grain growth following impingement.

LE " UNBALANCED SCORECARD " OU L'ANALYSE DE LA DIFFERENCIATION DES SYSTEMES DE MESURE DE LA PERFORMANCE (2003)

A partir des résultats d'une recherche empirique basée sur une enquête réalisée auprès de 83 entreprises, cet article montre que les systèmes de mesure de la performance sont, à la différence de ce que suggère le balanced scorecard, souvent " déséquilibrés ". La mesure de la performance tend à devenir plus " équilibrée " lorsque la taille de l'entreprise augmente et lorsque l'environnement organisationnel est complexe et incertain.

[Newer antimycotics. I. Derivatives of phenyl-hydrazine (author's transl)]. (1975)

The author produced a number of derivatives of phenyl-hydrazine and its analogues, investigated their antimicrobial efficiency in vitro, and discussed the association of chemical structure with the fungistatic effect in the series of phenyl-hydrazine-derivatives. From the author's results it can be concluded that the halogen-substituted phenyl-hydrazines and their N-(acetyl)-derivatives exert a moderate fungistatic effect (Tab. 1). In the series of N-aryl-sulphonyl-N'-phenyl-hydrazines only the compounds derived from 3,4-dichloro-phenyl-hydrazine proved to be effective; the other representatives of this type were fully ineffective (Tab. 1). The majority of the halogen-substituted N-aroyl-N'-phenyl-hydrazines exerted a relatively strong fungistatic activity with a broad spectrum of efficiency (Tab. 2). On the contrary, their analogues having a -CO-NH- group in place of the -CO-NH-NH-group, were fully inactive (Tab. 3). From the investigated derivatives of phenyl-hydrazine, the N-benzoyl-, N-(2-chloro-benzoyl)-, N-(4-chloro-benzoyl)- and N-furoyl-derivatives of 3- and 4-chloro-phenyl-hydrazine, furthermore the N-benzoyl- and N-furoyl-derivatives of 3,4-dichloro-phenyl-hydrazine were most effective (Tab. 2). The acute toxicity in the mouse of these effective compounds was relatively small; they were found to be significantly less toxic than tetramethyl-thiuramdisulfide (Tab. 4). On the basis of an intensive fungistatic efficiency and small toxicity of the halogen-substituted N-aroyl-N'-phenyl-hydrazines, it seems that a number of representatives of these types of chemical compounds could be given a role in the chemotherapy of superficial human and animal dermatomycoses, and also in the chemoprophylaxis of certain phytomycoses.
Segmented telescopes for coronagraphs (2004)

Use of a deployable telescope will be essential if the full science objectives of the Terrestrial Planet Finder mission are to be achieved with a visible coronagraph, since the largest monolithic mirrors that can be launched into space do not have the spatial resolution required to search the habitable zone around more than ~40 of the nearest stars. Current launch vehicle fairings limit the size of monolithic telescope mirrors to ~4 meters in diameter, or ~3.5-m x 10-m if the mirror is launched standing upright, and the telescope is unfolded after reaching orbit. By comparison, a telescope with two 3.5 x 7 meter segments could be launched and deployed autonomously to provide a 14-m elliptical aperture, and a telescope with six 4-m flat-flat hexagonal segments could be launched and deployed autonomously to provide a near-circular 12-m aperture with a single ring of segments (or 20-m if a second ring is added). Future NASA missions such as LifeFinder and planet imager will also require segmented, deployable telescopes to achieve the necessary collecting area. This paper discusses the issues associated with the use of segmented optics for coronagraphs and potential solutions.
Tumor-Enzymänderungen nach zytostatischerBehandlung eines menschlichen Darmtumorsim Goldhamster (1969)

Es wurde die spezifische Aktivität von Glukose-6-phosphatdehydrogenase (G6PDH ; EC 1.1.1.49) und Laktatdehydrogenase (LDH ; EC 1.1.1.27) bei Tumoren bestimmt, die eine Behandlung mit Actinomycin C (Sanamycin®, Bayer) und Cyclophosphamid (Endoxan®, Asta) erhielten. Als Tumor wurde das in der Backentasche unkonditionierter Goldhamster wachsende menschliche Kolonkarzinom, H. Ad. No. 1, verwendet. Durch Actinomycin wurde die spezifische Aktivität der Tumor-G6PDH regelmässig und signifikant gehemmt. Dieser Effekt zeigte sich als dosisabhängig und tumorspezifisch, da die spezifische Aktivität der Leber-G6PDH unverändert blieb. Auch die Aktivität der LDH wurde gehemmt, jedoch weniger konstant als die der G6PDH. Tumorwachstumshemmende Dosen von Cyclophosphamid hatten weder auf die G6PDH noch auf die LDH einen hemmenden Effekt. Die Ergebnisse zeigen, dass die G6PDH ein der Actinomycin-Therapie gegenüber besonders empfindliches Enzym ist, dessen Hemmung der starken wachstumshemmenden Wirkung auf H. Ad. No. 1 durch diese Verbindung zu entsprechen scheint. Da Cyclophosphamid bei wachstumshemmenden Dosen keine Enzymhemmung zeigte, hat es den Anschein, dass dieser Effekt nicht eine Folge der Antitumorwirkung an sich ist, sondern vielmehr in Zusammenhang steht mit dem besonderen Wirkungsmechanismus von Actinomycin, das die DNA-abhängige RNA-Synthese unterbricht. Da die LDH nur gelegentlich gehemmt wurde, ist weiterhin anzunehmen, dass bei dem untersuchten Tumor dem Pentosezyklus eine grössere Bedeutung zukommt als der anaeroben Glykolyse.
Effective Software Self-Test Methodology for Processor Cores (2002)

Software self-testing for embedded processor cores based on their instruction set, is a topic of increasing interest since it provides an excellent test resource partitioning technique for sharing the testing task of complex systems-on-chip (SoC) between slow, inexpensive testers and embedded code stored in memory cores of the SoC. We introduce an efficient methodology for processor cores self-testing which requires knowledge of their instruction set and Register Transfer (RI) level description. Compared with functional testing methodologies proposed in the past, our methodology is more efficient in terms of fault coverage, test code size and test application time. Compared with recent software based structural testing methodologies for processor cores, our methodology is superior in terms of test development effort and has significantly smaller code size and memory requirements, while virtually the same fault coverage is achieved with an order of magnitude smaller test application time.

Resin/fiber thermo-oxidative interactions in PMR polymide/graphite composites (1979)

The amounts of resin weight loss and fiber weight loss in four PMR-polyimide graphite fiber composites were calculated from the composite weight losses and the fiber/resin ratios of the composites after long term thermo-oxidative aging in 600 F air. The accelerating effect of graphite fiber on resin weight loss, compared to neat resin weight loss, indicated the presence of a deleterious resin/fiber thermo-oxidative interaction, presumably due to fiber impurities. Similarly, the decelerating effect of the protective matrix resin on fiber weight loss, compared to bare fiber weight loss, was also demonstrated. The amount of hydrazine-indigestible resin and the amount of loose surface graphite fiber that formed during 600 deg F exposure of the composites were quantitatively determined. The indigestible residual resin was also qualitatively studied by scanning electron microscopy.
Urbano V: Vacanze romane (2011)

Matcha addition decreased the relative crystallinity and provided with a refreshing flavor for all types of rice cakes. Matcha also significantly enhanced the phenolic content and the oxidant defense of cakes. Compared with the other two types of rice cakes, the one made of glutinous rice are with the lowest starch digestibility. Adding matcha to rice cakes inhibited the <i>in vitro</i> starch digestion, and a significant decrease in the expected glycemic index (eGI) and an increase in resistant starch (RS) were observed. Besides, according to the results of sensory evaluation, an optimized formulation of matcha rice cake was expected to contain 1.6% matcha, 82% water and steamed for 39 min. These findings suggest that matcha could be a favorable food additive to improve both the flavour and nutritional value of steamed rice cake.

Osteoclast formation together with interleukin-6 production in mouse long bones is increased by insulin-like growth factor-I (1992)

Insulin-like growth factor-I (IGF-I) is a potent stimulator of bone formation. Whether this growth factor also induces bone resorption has not been studied in detail. We used two organ culture systems to examine the direct effect of IGF-I on bone resorption. Fetal mouse radii/ulnae, containing mature osteoclasts, showed no response to IGF-I, indicating that osteoclastic activity is not influenced by IGF-I. Fetal mouse metacarpals/metatarsals, containing just osteoclast precursors and progenitors, showed an increase in resorption in response to IGF-I, indicating that IGF-I stimulates the formulation of osteoclast precursors/progenitors and thereby increases the number of osteoclasts. Interleukin-6 (IL-6) has been hypothesized to be a mediator of bone resorptive agents such as parathyroid hormone (PTH). Both radii/ulnae and metacarpals/metatarsals reacted to IGF-I with an increase in IL-6 production. IL-6 production by UMR-106 osteogenic osteosarcoma cells was positively modulated by IGF-I, indicating that osteoblasts are likely to be the cells responsible for increased IL-6 production by the bones, and that IL-6 might be a mediatory of IGF-I-stimulated bone resorption.
Detection of human polyomavirus proteins, T‐antigen and agnoprotein, in human tumor tissue arrays (2010)

Expression of the human polyomavirus JCV genome in several experimental animals induces a variety of neural origin tumors. The viral proteins, T-antigen and Agnoprotein, contribute to the oncogenesis of JCV by associating with several tumor suppressor proteins and dysregulating signaling pathways, which results in uncontrolled cell proliferation. In addition, T-antigen and Agnoprotein have been associated with DNA damage and interfering with DNA repair mechanisms. In this study, we have utilized commercially available tissue arrays of human tumors of various origins and demonstrated the expression of both T-antigen and Agnoprotein in some, but not all, tumors of neural and non-neural origin. Most notably, more than 40% of human glioblastomas and greater than 30% of colon adenocarcinomas express viral proteins. The detection of viral transforming proteins, T-antigen and Agnoprotein in the absence of viral capsid proteins suggests a role for JCV in the development and/or progression of human tumors. These results invite further large-scale investigation on the role of polyomaviruses, particularly JCV in the pathogenesis of human cancer.

West Nile virus: recent experience with the model virus approach. (2004)

During recent West Nile Virus (WNV) epidemics in the USA, virus transmissions through transfusion of blood components have been observed, also raising concerns about the safety of plasma derivatives. To verify the safety margins of these products, as initially shown using model viruses very similar to WNV, virus inactivation procedures incorporated into their manufacturing processes were re-investigated using WNV directly. The results show that WNV behaves exactly as had been predicted based on available data for similar ("model") viruses, i.e. it is readily inactivated by e.g. pasteurisation of human albumin, solvent-detergent treatment of intravenous immunoglobulin and factor VIII, vapour heating of factor VIII inhibitor by-passing activity, and incubation of intravenous immunoglobulin at low pH. Our investigation thus verifies the safety margins of plasma derivatives against Flaviviruses in general, and now WNV in particular. Also, use of the model virus concept was confirmed to be well capable of predicting the behaviour of a certain virus based on available data for closely related viruses.
Detection and discrimination of moving stimuli: the effects of color, luminance, and eccentricity (1994)

Psychophysical detection and direction discrimination thresholds for 1c/o, 1-Hz Gabors are plotted in a Weberian long-middle-wavelength-sensitive cone contrast plane. The shape of these threshold contours suggests linear cone contributions to additive (delta L/Lb + delta M/Mb) and opponent (delta L/Lb - delta M/Mb) postreceptoral mechanisms. The opponent mechanism dominates thresholds at the fovea, but sensitivity decreases rapidly with eccentricity in comparison with the additive mechanism. Cone contributions to the mechanisms vary in a small and nonsystematic manner across the retina. The experiments show that the additive mechanism is directionally sensitive at detection threshold. At all eccentricities studied (0-24 degrees), 0.3-log-unit suprathreshold contrasts are necessary for the opponent mechanism to signal direction of motion.
Discrimination of five-component tonal complexes differing in crest factor (1986)

Hartman et al. [J. Acoust. Soc. Am. 79, 1915–1925 (1986)] presented data on discrimination of tonal complexes differing only in number of spectral components within a fixed bandwidth. The Hartmann et al. data suggested that discrimination could be based upon perception of temporal fluctuations in the intensity levels of the sounds, or upon the detail of the spectral structure of the complexes. The present experiment assessed discrimination of tonal complexes that differed in only the phase relationships among five fixed frequency components. The phase relationships established a range of crest factors (peak/rms amplitude) for the complexes. When presented at equal loudness, the tonal complexes were easily discriminable by a musically trained subject, and were discriminable by all subjects with training. The data from the current study support a model of discrimination based only upon the temporal fluctuations in the complex envelopes. Discrimination between tonal complexes can be made for complexes differing either in rate or depth of such fluctuations, as long as the fluctuations are within the limits of temporal integration of the car.
Blood myeloid dendritic cell reduction and differences between myocarditis and dilated cardiomyopathy (2013)

Aims: The role of dendritic cells (DCs) in cardiomyopathies is unknown yet. Dilated cardiomyopathy (DCM) is often preceded by myocarditis, hence the two conditions often clinically overlap. In order to investigate the role of DCs in diagnosing myocarditis/DCM, we prospectively investigated the circulating DC precursors (DCPs) as well as mature DCs in endomyocardial biopsies (EMBs) from patients with acute myocarditis and newly diagnosed DCM. Methods: Blood myeloid (mDCPs) and plasmacytoid (pDCPs) DC precursors were flow cytometrically analyzed in patients with newly onset heart failure (HF) and biopsy proven DCM (n=43, mean EF 29±10%) and patients with MRI confirmed myocarditis (n=23). Individuals with excluded heart disease were used as controls (n=52). Left-ventricular EMBs were performed when clinically indicated (n=45) and were immunohistologically analyzed for the presence of mature myeloid DCs (CD83+) and tissue fibrosis (Sirius red). Analyses of circulating DCPs were performed initially and at repeated follow-up intervals of 6 months. Correlation analysis was performed between circulating DCPs and mature DCs in EMBs, as well as clinical, echocardiographic and invasive left-ventricular parameters. Results: Relative and absolute numbers of circulating mDCPs were reduced in patients with myocarditis compared to controls (0.065% vs 0.2%,p<0.001). Following clinical recovery of myocarditis, circulating mDCPs tended to normalise (0.015% vs 0.2%,p=0.008). Circulating mDCPs of DCM patients were at initial presentation unchanged compared to controls (0.18% vs 0.2%,p=0.258), but were significantly reduced at 6- and 12-month-follow-up (0.16% vs 0.2%,p=0.047 and 0.14% vs 0.2%,p=0.021). No statistical significance was observed for pDCPs. Correlation analysis revealed inverse correlation of blood mDCPs with myocardial mature DCs in EMBs (r=-0.522,p=0.026). We also found an inverse correlation of blood mDCPs with cTNI (r=-0.826,p<0.001), CRP (r =-0.388,p=0.014), invasively measured EF (r=-0.383,p=0.026), but not BNP (p=0.921). Blood mDCPs positively correlated with tissue fibrosis (r=0.395,p=0.05), mitral and tricuspid regurgitation (r=0.395,p=0.012 and r=0.47,p=0.002). Conclusions: Circulatory mDCs migrated into the myocardium of these patients. While their peripheral reduction was acute in myocarditis, it was delayed and chronic/progressive in DCM. Thus, inflammatory processes in DCM were not causative, but rather secondary to structural myocardial changes. DCs could prove to be discriminatory between myocarditis and DCM in early diagnosis.
