Eurogeomars Field Campaingn: Sample Analysis of Organic Matter and Minerals (2010)

A strategic search for life on Mars re- quires a thorough interdisciplinary preparation phase that includes the optimization of sample analysis tech- niques, instrument development and calibration and extensive terrestrial field tests at Mars analog sites. In this paper, we report on the results of chemical, physi- cal and astrobiological measurements of samples col- lected during the EuroGeoMars campaign at Utah Mars Desert Research Station (MDRS) in February 2009 (see Figure 1). EuroGeoMars MDRS campaign: The goal of the EuroGeoMars campaign (from 24 January to 28 Feb- ruary 2009) sponsored by ESA, NASA and ILEWG (1) was to demonstrate instruments from the ExoGeo- Lab pilot project (2), support the interpretation of on- going planetary missions, validate a procedure for Martian surface in-situ and return science, and study human performance aspects (3). Several science and exploration instruments were either brought from Europe or by US collaborators.

Stimulus-Dependent Synchronization of Neuronal Assemblies (1993)

We study theoretically how an interaction between assemblies of neuronal oscillators can be modulated by the pattern of external stimuli. It is shown that spatial variations in the stimuli can control the magnitude and phase of the synchronization between the output of neurons with different receptive fields. This modulation emerges from cooperative dynamics in the network, without the need for specialized, activity-dependent synapses. Our results further suggest that the modulation of neuronal interactions by extended features of a stimulus may give rise to complex spatiotemporal fluctuations in the phases of neuronal oscillations.
Generation of free ubiquitin chains is up-regulated in stress and facilitated by the HECT domain ubiquitin ligases UFD4 and HUL5 (2012)

Polyubiquitin chains serve a variety of physiological roles. Typically the chains are bound covalently to a protein substrate and in many cases target it for degradation by the 26S proteasome. However, several studies have demonstrated the existence of free polyubiquitin chains which are not linked to a specific substrate. Several physiological functions have been attributed to these chains, among them playing a role in signal transduction and serving as storage of ubiquitin for utilization under stress. In the present study, we have established a system for the detection of free ubiquitin chains and monitoring their level under changing conditions. Using this system, we show that UFD4 (ubiquitin fusion degradation 4), a HECT (homologous with E6-AP C-terminus) domain ubiquitin ligase, is involved in free chain generation. We also show that generation of these chains is stimulated in response to a variety of stresses, particularly those caused by DNA damage. However, it appears that the stress-induced synthesis of free chains is catalyzed by a different ligase, HUL5 (HECT ubiquitin ligase 5), which is also a HECT domain E3.
A New Labdane Diterpenoid from <i>Renealmia</i> <i>a</i><i>lpinia</i> Collected in the Suriname Rainforest (1999)

Continuation of a previous study on Renealmia alpinia resulted in the isolation of the new labdane diterpenoid 3, together with two known diterpenoids. The structure of the new diterpenoid was determined by a combination of NMR techniques and HRFABMS.
Multilayer Image Grid Reconstruction Technology: Four-Dimensional Interactive Image Reconstruction of Microsurgical Neuroanatomic Dissections (2006)

MIGRT uniquely focuses on capturing anatomic content that preserves natural appearances, including procedure, texture, and color, which is far superior and preferable to images and a reconstructed image environment based on artificial or animated concepts. MIGRT shows time-dependent changes in procedures, provides depth perception by stereoscopy or unique sequential motion, and allows simultaneous interactivity at each step of the procedure.
QoS-constrained physical layer optimization for correlated flat-fading wireless channels (2004)

In next generation data networks, joint optimization of physical layer parameters and scheduling layer parameters will be necessary to meet the demands of quality of service (QoS)-constrained traffic like video traffic. Until now, such optimization problems considered only simple and non-realistic Markov chain models to represent physical layer channel dynamics. In this paper, we consider the incorporation of realistic channel models in a Markov decision process (MDP) formulation for the QoS-constrained optimization of the physical layer. The channel random process is transformed into an extended Markovian setup through hidden Markov models (HMM) and the solution of the resulting optimization problem is shown to be a partially observable Markov decision process (POMDP). The optimal scheduling agent bases its decision on a parameter that summarizes complete system history until the decision instant. This parameter can he computed at each decision instant based only on newly available information, avoiding the need to record all the past states.
1054 Noninvasive Qp/Qs ratio measurement with phase-contrast cine MRI in patients with atrial septal defect: comparison with heart catheterization (2008)

The correlation analysis showed a good overlap between measurements (Qp: r = 0.65, p = 0.0004; Qs: r = 0.64, p = 0.0005; Qp/Qs ratio: r = 0.68, p = 0.0002), also confirmed by regression analysis (R2 = 0.42, p < 0.001 for Qp; R2 = 0.41, p = 0.001 for QS; R2 = 0.46, p < 0.001 for Qp/Qs ratio), and by the Bland-Altman statistical analysis for method comparison (see Figure 1). The interobserver variability was low.
Development and piloting of a food‐based intervention to increase vitamin E intake in pregnant women in a randomized controlled trial (2016)

Low maternal vitamin E intake during pregnancy is associated with childhood asthma and a trial is required to test whether increasing maternal vitamin E intake reduces childhood asthma. This study investigated whether such a trial is possible using food to increase vitamin E intake. Three soup varieties with enhanced vitamin E content (16-19 mg/can) from food ingredients were developed. Near identical retail versions (vitamin E 1-4 mg/can) acted as placebo. In a pilot double-blind randomized controlled trial, pregnant women were randomized 1:1 to enhanced or placebo soups (three tins/week) from 12 weeks gestation to delivery. Vitamin E intake was quantified at 12, 20, and 34 weeks gestation. Qualitative interviews were conducted. 59 women were randomized (29 enhanced, 30 placebo), 28 completed the trial, (15 enhanced, 13 placebo). In women completing the trial, vitamin E intake of the placebo group remained unchanged; 7.09 mg/d (95% CI 5.41-8.77) at 12 weeks, 6.41 mg/d (5.07-7.75) at 20 weeks, and 6.67 mg/d (5.38-7.96) at 34 weeks gestation; vitamin E intake of the enhanced group increased from 6.50 mg/d (5.21-7.79) at 12 weeks to 14.9 mg/d (13.3-16.4) at 20 weeks and 15.2 mg/d (12.9-17.5) at 34 weeks, <i>P </i>< 0.001. Qualitative interviewing provided clear guidance on improving adherence. Although 31 women withdrew at median 19 weeks gestation (interquartile range 16-25), the intervention was consumed by women for 80% of weeks between 12 and 34 weeks gestation and for 63% of weeks between 12 weeks gestation and delivery. In a pilot double-blind randomized controlled trial (RCT) it is possible to increase maternal vitamin E intake using food ingredients, a further food product is required to improve adherence.
Computer-aided detection of colonic polyps with level set-based adaptive convolution in volumetric mucosa to advance CT colonography toward a screening modality (2009)

Computer-aided detection of colonic polyps with level set-based adaptive convolution in volumetric mucosa to advance CT colonography toward a screening modality Hongbin Zhu1, Chaijie Duan1, Perry Pickhardt2, Su Wang1, Zhengrong Liang1,31Department of Radiology, 3Department of Computer Science, State University of New York, Stony Brook, NY, USA; 2Department of Radiology, University of Wisconsin Medical School, Madison, WI, USAAbstract: As a promising second reader of computed tomographic colonography (CTC) screening, the computer-aided detection (CAD) of colonic polyps has earned fast growing research interest. In this paper, we present a CAD scheme to automatically detect colonic polyps in CTC images. First, a thick colon wall representation, ie, a volumetric mucosa (VM) with several voxels wide in general, was segmented from CTC images by a partial-volume image segmentation algorithm. Based on the VM, we employed a level set-based adaptive convolution method for calculating the first- and second-order spatial derivatives more accurately to start the geometric analysis. Furthermore, to emphasize the correspondence among different layers in the VM, we introduced a middle-layer enhanced integration along the image gradient direction inside the VM to improve the operation of extracting the geometric information, like the principal curvatures. Initial polyp candidates (IPCs) were then determined by thresholding the geometric measurements. Based on IPCs, several features were extracted for each IPC, and fed into a support vector machine to reduce false positives (FPs). The final detections were displayed in a commercial system to provide second opinions for radiologists. The CAD scheme was applied to 26 patient CTC studies with 32 confirmed polyps by both optical and virtual colonoscopies. Compared to our previous work, all the polyps can be detected successfully with less FPs. At the 100% by polyp sensitivity, the new method yielded 3.5 FPs/dataset. Keywords: colonic polyps, level set, adaptive convolution, middle-layer enhanced integration, volumetric mucosa, support vector machine, computer-aided detection, CT colonography
Synthetic pheromones as a management technique – dispensers reduce <i>Linepithema humile</i> activity in a commercial vineyard (2015)

Our results showed that pheromone dispensers can significantly reduce Argentine ant foraging in grapevines if they are positioned appropriately. This technique could potentially reduce the abundance of associated mealybugs and potentially attendant virus vectoring areawide.

Grafting reactions onto poly(organophosphazenes). IV. Light‐induced graft copolymerization of organic polymers containing free acid or basic functionalities onto poly[bis(4‐benzylphenoxy)phosphazene] (1995)

Abstract The light‐induced graft copolymerization of acrylic acid, methacrylic acid, and 4‐vinylpyridine onto poly[bis(4‐benzylphenoxy)phosphazene] films to prepare new grafted phosphazene copolymers containing acid and basic functionalities is reported. The process was carried out in monomer/methanol mixtures in the presence of benzophenone or benzoin ethyl ether as photosensitizers by selective excitation of these last species. The yield of the grafting processes was evaluated as a function of the monomer concentration in the reaction medium, type of photoinitiator, and characteristics of the grafted organic monomers. The acid functions inserted in poly[bis(4‐benzylphenoxy)phosphazene]‐ g ‐poly(meth)acrylic acid grafted copolymers, and the basic groups of the poly[bis(4‐benzylphenoxy)phosphazene]‐ g ‐poly‐4‐vinylpyridine substrates were allowed to interact with basic and acid dyes, respectively, to form permanently colored polymeric films. The photoactivity of these films as substrates for the photosensitized production of singlet oxygen was tested. © 1995 John Wiley & Sons, Inc.

Studies on the haemostatic defect in a complicated syndrome. An inverse Scott syndrome platelet membrane abnormality? (1995)

The Stormorken syndrome is a multifacetted syndrome including a bleeding tendency. No deviations were found in the coagulation- or fibrinolytic systems. Platelet number was low normal, and size abnormal, whereas EM findings were unremarkable. Survival time was half normal. Clot retraction was initially rapid, but clearly decreased, whereas prothrombin consumption was also initially rapid, but complete. Membrane GP's were normal, so was AA metabolism, PI-cycle, granule storage and secretion, and c-AMP function, whereas 5-HT uptake and storage was decreased. Optical platelet aggregation was low normal with all physiological agonists. The only clearly abnormal finding was that coagulant activity was present on non stimulated platelets at the same level as kaolin-stimulated normal platelets. This indicated a platelet abnormality which should lead to a thrombogenic, not to a haemorrhagic trait. This paradox may have its origin in rheology, because when challenged with in vivo shear rates in an ex vivo perfusion chamber, platelet cohesion was abnormally low. Further studies to better delineate the membrane abnormality are underway.
An investigation of holographic correctors for astronomical telescopes (1993)

Fixed telescopes are considerably less expensive than tiltable ones but can only access a limited region of the sky. To extend their field of view, we have investigated the use of holographic elements. We have used the scalar approximation to compute holographic correctors for a 4-m diameter f/4 parabolic primary mirror. We identify a few critical areas of research. The computation of the reference wave needed for our holographic correctors is presently limited by computing power, because of the large parameters of the mirror at optical wavelengths. Our computations show that it is possible to achieve an excellent correction with a single CGH for monochromatic light at the recording wavelength

Stress-induced anisotropy of graphitelike amorphous carbon (2007)

Ellipsometry spectra of graphitelike amorphous carbon films on Si reveal a strong anisotropy of the optical constants in the 0.7–9.5eV photon-energy range. The films are optically uniaxial, with the optical axis oriented normal to the surface. This birefringence can be explained by ordering of the hexagonal graphene planes perpendicular to the substrate due to tensile stress, which was confirmed by transmission electron microscopy. All films show two peaks in the optical absorption, corresponding to the ordinary and extraordinary absorption peaks in graphite.
Comparison Perioperative Factors During Minimally Invasive Pre-Psoas Lateral Interbody Fusion of the Lumbar Spine Using Either Navigation or Conventional Fluoroscopy (2017)

Compared with C-ARM techniques, using navigation can eliminate RE to surgeon and decrease RE to the patient, and it had no significant effect on operating time, estimated blood loss, length of hospitalization, or perioperative complications in the patients with OLIF procedure. This study shows that navigation is a safe alternative to fluoroscopy during the OLIF procedure in the treatment of degenerative lumbar conditions.
<title>Design and manufacture of a prototype 4-waveband scanning thermal imager</title> (1990)

The Multiband Electro-Optical Scanner is an experimental laboratory demonstrator, the purpose of which is to investigate the feasibility of missile detection using a scanning thermal imager in a number of discrete wavebands. The demonstrator utilizes three mid-IR wavebands and one FIR waveband to discriminate spectrally between real targets and false background clutter. The narrow instantaneous fields of view of these four detectors are scanned using broadband reflective optics common to all four beams, to provide a field of 3.5 x 10 deg. The signals from two reference blackbody sources are injected once per frame to provide radiometric calibration. The system design is described, illustrating the impact of optomechanical design on systems considerations.

An additional mechanism of growth restriction in T cell line H9 of human immunodeficiency virus type 1 isolates from asymptomatic homosexual men (1996)

The replicative properties of human immunodeficiency virus type 1 (HIV-1) isolates from asymptomatic carriers (asymptomatic isolates) and AIDS patients (AIDS isolates) were examined in the human T lymphocyte cell line H9. In agreement with earlier reports the replication of asymptomatic isolates was restricted whereas AIDS isolates replicate well in H9 cells. PCR analysis of H9 cells infected with asymptomatic isolates showed transient gag DNA synthesis for up to 48 h post-infection. This transient DNA synthesis was much lower than the amount of DNA synthesized by the AIDS isolates. The reduction in DNA synthesis reflects a restriction during virus entry. We further analysed transient DNA synthesis by the asymptomatic isolates to investigate possible post-entry restriction mechanisms. The transiently synthesized DNA was present only in the unintegrated form and was not transported in to the nucleus, suggesting an additional restriction mechanism for asymptomatic isolates in H9 cell lines at a step post-DNA synthesis and prior to or during nuclear translocation of newly synthesized viral DNA.
Low-noise backward-wave amplifiers (1958)

The characteristics of backward-wave amplifiers are briefly reviewed and related to general receiver problems which exist in broad-band high-power systems. It is emphasized that a backward-wave amplifier of sufficiently low noise figure offers potential solution to several of these problems and would be more useful in some cases than a conventional low-noise traveling-wave tube. The problems encountered in noise reduction in backward-wave amplifiers are discussed and compared with those for forward-wave amplifiers. Gain, bandwidth, and noise-figure characteristics of experimental S-band tubes are presented. Very low noise figures have been achieved for tuning ranges up to half an octave with minimum programming of the gun potentials. A noise figure of 3.7 db at the center of the tuning range has been attained and was reproducible after several hundred hours of operation. This node figure is well below the usual theoretical minimum and is made possible by the unique geometry of the annular cathode and gun. The results to date indicate that the backward-wave type of amplifier is feasible for receiver applications and may satisfy the increasingly apparent need for rapidly tunable selective preamplification.
Intervenção coronária percutânea no mundo real: tão eficiente quanto nos estudos publicados, mas será que o aumento do uso de stents farmacológicos pode melhorar ainda mais os resultados? (2009)

present their collective ex-perience with percutaneous coronary intervention(PCI) from a single center over a 12 year period. Thiseffort is commendable as it provides a snapshot ofreal-world practice not subject to inclusion or exclusioncriteria or selection bias that invariably occurs withprospective clinical trials and multicenter registries.Two thirds of the patient’s treated had complex typeB2/C lesions and more than half of the patients pre-sented with unstable angina or acute myocardialinfarction. In this unselected consecutive series, theprocedural success was a remarkable 97.1% with earlystent thrombosis rate of only 0.39%. The 30-dayoutcomes are in line or better than the results in themost recently published large-scale multicenterobservational registries of coronary PCI
