Electron emission from metal surfaces excited by intense femtosecond pulses (1993)

Summary form only given. In order to understand quantitatively the electron yield and energy distribution and to develop a useful diagnostic technique, the authors present a combined experimental, analytical theory, and particle simulation investigation of femtosecond pulse induced electron emission from Al, Ag and W surfaces. Al [110], Ag [111], and W [100] samples in an ultrahigh vacuum chamber (P < 1 /spl times/ 10/sup -10/ torr) were excited by 90 fs, 2.0 eV laser pulses. In the analytical theory an effective space-charge potential barrier was added to the inner potential for the removal of an electron in the Richardson thermionic emission rate equation. Particle-in-cell computer simulation results confirm the analytic model. New emission mechanisms are shown to appear as a solid density plasma is formed and surface integrity is lost.

Survey of Winter Wheat (Triticum aestivum) Stubble Fields Sprayed with Herbicides After Harvest in 1986 (1989)

A survey of 146 fields was conducted to investigate herbicide performance in winter wheat-producing areas of southwestern Nebraska during August and September of 1986. Only 55% of the fields received an excellent rating for weed control and stubble quality; one third rated as unacceptable. Weed control after wheat harvest was improved by planting ‘Bounty 310’, ‘Siouxland’, ‘Vona’, and ‘Centura’ winter wheat cultivars rather than ‘Mustang’, ‘Hawk’, ‘Pioneer 2656’, and ‘Wings'. Fertilizing winter wheat in the fall, planting wheat at the optimum date, high wheat stem density, using a winter wheat-corn-fallow rotation, not spraying herbicides after wheat harvest on days that it rained or air temperature exceeded 35 C, and spraying weeds when they were small also improved weed control in wheat stubble. Nine months after wheat harvest, fields treated with atrazine before July 16 had more volunteer wheat than fields treated later.
Faster Cognitive Decline in Dementia due to Alzheimer Disease with Clinically Undiagnosed Lewy Body Disease (2019)

Abstract Neuropathology has demonstrated a high rate of comorbid pathology in dementia due to Alzheimer’s disease (ADD). The most common major comorbidity is Lewy body disease (LBD), either as dementia with Lewy bodies (AD-DLB) or Alzheimer’s disease with Lewy bodies (AD-LB), the latter representing subjects with ADD and LBD not meeting neuropathological distribution and density thresholds for DLB. Although it has been established that ADD subjects with undifferentiated LBD have a more rapid cognitive decline than those with ADD alone, it is still unknown whether AD-LB subjects, who represent the majority of LBD and approximately one-third of all those with ADD, have a different clinical course. Subjects with dementia included those with “pure” ADD (n = 137), AD-DLB (n = 64) and AD-LB (n = 114), all with two or more complete Mini Mental State Examinations (MMSE) and a full neuropathological examination. Linear mixed models assessing MMSE change showed that the AD-LB group had significantly greater decline compared to the ADD group (β = −0.69, 95% CI: −1.05, −0.33, p&lt;0.001) while the AD-DLB group did not (β = −0.30, 95% CI: −0.73, 0.14, p = 0.18). Of those with AD-DLB and AD-LB, only 66% and 2.1%, respectively, had been diagnosed with LBD at any point during their clinical course. The probable cause of LBD clinical detection failure is the lack of a sufficient set of characteristic core clinical features. Core DLB clinical features were not more common in AD-LB as compared to ADD. Compared with clinically-diagnosed AD-DLB subjects, those that were clinically undetected had significantly lower prevalences of parkinsonism (p = 0.046), visual hallucinations (p = 0.0008) and dream enactment behavior (0.013). Clinical identification of ADD with LBD would allow stratified analyses of ADD clinical trials, potentially improving the probability of trial success.

Optimisation-based motion planning with obstacles and priorities (2017)

The goal of this work is to explore ways of generating state trajectories for dynamical systems subject to computational constraints, obstacles and priority assignment. The algorithms are developed for a miniature unmanned aerial vehicle (UAV) in a modular fashion and include (1) a genetic algorithm (GA) for solving the travelling salesman problem (TSP) with respect to priorities and obstacle avoidance, (2) a projective algorithm (PA) for finding the shortest paths around obstacles, (3) a quadratic program (QP) for minimum-snap polynomial trajectory generation subject to equality constraints to guarantee avoidance of static obstacles. Combined, the algorithms enable simple and computationally efficient motion planning with support in both R2 and R3 exemplified in a real-time implementation.
k-Space tutorial: an MRI educational tool for a better understanding of k-space (2008)

A main difference between Magnetic Resonance (MR) imaging and other medical imaging modalities is the control over the data acquisition and how it can be managed to finally show the adequate reconstructed image. With some basic programming adjustments, the user can modify the spatial resolution, field of view (FOV), image contrast, acquisition velocity, artifacts and so many other parameters that will contribute to form the final image. The main character and agent of all this control is called k-space, which represents the matrix where the MR data will be stored previously to a Fourier transformation to obtain the desired image.This work introduces 'k-Space tutorial', a MATLAB-based educational environment to learn how the image and the k-space are related, and how the image can be affected through k-space modifications. This MR imaging educational environment has learning facilities on the basic acceleration strategies that can be encountered in almost all MR scanners: scan percentage, rectangular FOV and partial Fourier imaging. It also permits one to apply low- and high-pass filtering to the k-space, and to observe how the contrast or the details are selected in the reconstructed image. It also allows one to modify the signal-to-noise ratio of the acquisition and create some artifacts on the image as a simulated movement of the patient - with variable intensity level - and some electromagnetic spikes on k-space occurring during data acquisition.

Ab initio static polarizability and first hyperpolarizability of model polymethineimine chains. II. Effects of conformation and of substitution by donor/acceptor end groups (1997)

An ab initio coupled Hartree–Fock study has been carried out on polymethineimine (PMI) oligomers with an increasing number of unit cells (up to N=20) to determine the effect of conformational differences, and of end-capping by a strong donor-acceptor pair, on the static electronic longitudinal polarizability (αL) and first hyperpolarizability (βL). For the unsubstituted polymer the differences in βL per unit cell among the four conformations examined—trans-transoı̈d (TT), cis-transoı̈d (CT), trans-cisoı̈d (TC) and helical (HEL)—are large. βL/N is positive for the CT polymer, in contrast with the other conformers and with μL/N, which is negative in all cases. The TC polymer has the largest |βL|/N despite having a relatively small αL/N. Substitution of a strong acceptor (NO2) at the carbon end of an oligomer and a strong donor (NH2) at the nitrogen end results in a large increase of βL/N for small/medium N. In the case of the TT and, particularly, the CT conformer this leads to a maximum in |βL|/N vs N at N=4–6, which is substantially greater in magnitude than the one at N=∞. The latter is unaffected by substitution. We compare the [βL(N)/N]max obtained at intermediate N for substituted PMI chains with those calculated for linear polyenes and other π-conjugated oligomers. The shape of all the βL/N vs N curves obtained is fit to a function which yields parameters characterizing the delocalization along the backbone, the unit cell asymmetry, and the asymmetry of the chain ends.
Granular flow, segregation and agglomeration in bladed mixers (2010)

A large number of industrial processes involve the transport, mixing and storage of particulate systems. While prevalent in industry, particulate processes are commonly plagued by problems due to the complex rheology of these systems. In this work, the behavior of granular materials in a bladed mixer, an industrially relevant geometry, was investigated using computational and experimental techniques. Experimental flows were characterized via Particle Image Velocimetry and image analysis. Discrete element simulations were carried out to examine the effect of a wide range of system parameters. Particulate flows in bladed mixers were found to be periodic with complex flow patterns developing throughout the particle bed. Cohesionless flows were initially studied. For monodisperse flows, two distinct flow regimes were observed: a quasi-static regime where blade speed provides the time scale for momentum transfer and an intermediate regime where stresses scale linearly with blade speed. Particle and wall roughness were found to significantly affect bladed mixer flows. Systems with higher roughness are characterized by enhanced particle motion and mixing. Simple scaling relationships were observed for monodisperse flows in the quasi-static regime. Particle velocities and diffusivities were found to scale linearly with mixer size and blade speed, while stresses scaled linearly with particle bed weight. In polydisperse flows, size segregation was found to occur due to sieving. However, it was found that the extent of segregation can be reduced by introducing intermediate particle sizes in between the smallest and largest particles. Finally, wet particle flows were examined. At low moisture contents, enhanced particle velocities and mixing kinetics were observed in comparison to dry flows. However, at higher moisture contents, particle velocities and mixing rates were observed to decrease. Wet particle flows were characterized by the formation of particle agglomerates. Agglomerate formation led to an increase in particle bed roughness which significantly influenced macroscopic and microscopic flow properties. These findings contribute to the understanding of granular behavior in complex systems. Improved understanding of granular flows will enable the development of first-principles based models which can assist in the design and scale-up of bladed mixer operations and the identification of critical processes parameters.

Surface Coating of a Metal Mesh Device Sensor With Gold to Improve the Separation and Sensing of Mammalian Cells (2016)

Separation and detection of particular cells from culture media and clinical specimens is important for cell engineering and clinical examination. In this paper, we developed a metal mesh device (MMD) in which a thin nickel mesh with periodic microstructures consisting of square apertures plays a pivotal role in cellular fractionation and sensing. The mesh aperture in our 100-THz MMD had a side length of 1.8 μm. This size of aperture was suitable for optically sensing mesh-captured particles by detecting transmittance of the corresponding electromagnetic waves, and simultaneously functioned as a sieve to separate microspheres according to their size. HeLa cells could be selectively captured by filtration through the 100-THz MMD, and the captured cells were detected by infrared transmittance changes. Coating of the mesh with gold improved sensing capability by sharpening of the transmittance peak. Most (98%) HeLa cells captured on the gold-coated mesh were viable and proliferated normally when re-cultured. When a mixture consisting of HeLa cells and an excess number of erythrocytes was filtered, HeLa cells were captured on the mesh, whereas erythrocytes were not, even though the average size of erythrocytes was much larger than the mesh aperture. Thus, gold-coated mesh may be useful for separating solid tumor-derived circulating cancer cells from erythrocytes, a major blood cell type. In addition, metal mesh-aided recovery of mammalian cells from cultures without cellular damage may facilitate the large-scale culture in cell biotechnology, because centrifugation, a laborious process for harvesting cells, becomes dispensable.
The Stability Challenge on the Pathway to Low and Ultra‐Low Platinum Loading for Oxygen Reduction in Fuel Cells (2015)

We report the influence of catalyst loading on rates of platinum degradation in acidic electrolyte at room temperature. A piezoelectric printer is used to deposit spotted arrays of a commercially available catalyst comprised of Pt nanoparticles on a porous carbon support. The kinetically controlled oxygen reduction reaction (ORR) activity at different loadings is measured using an electrochemical scanning flow cell (SFC), and found to be quite stable over the range of loadings studied. This behaviour, however, contrasts sharply with rates of both transient and quasi-steady-state platinum dissolution. These are shown using downstream inductively coupled plasma mass spectrometry (ICP-MS) analytics, to increase as loading becomes lower. This dichotomy between activity and stability has direct implications for the development of improved catalyst materials, as well as for the achievement of current targets for reduced loadings of noble metals for fuel cells and other energy storage devices.

Isolation and characterization of a Pseudomonas aeruginosa gene, ptxR, which positively regulates exotoxin A production (1996)

Exotoxin A production in Pseudomonas aeruginosa is a complicated and highly regulated process that involves several genes. In this report, we describe the isolation of a new toxA regulatory gene (ptxR) which affects exotoxin A production in P. aeruginosa. In an iron-deficient medium, the presence of a plasmid carrying ptxR in P. aeruginosa PAO1 resulted in a four-to fivefold increase in exotoxin A synthesis. No effect was observed on the levels of elastase, phospholipase C, exoenzyme S, and alkaline protease. Using subcloning and complementation experiments, ptxR was localized to a 2.1 kb Kpnl-Bg/II fragment. Nucleotide sequence analysis revealed the presence of an open reading frame which encodes a 34.97 kDa protein (PtxR). The size of the predicted PtxR compares closely with the 34 kDa PtxR that was synthesized in Escherichia coli using the T7 expression system. The deduced amino acid sequence of PtxR is homologous to that of several members of the LysR family of transcriptional activators. The amino-terminus region of PtxR contains a putative helix-turn-helix DNA-binding motif. Specific ptxR-deletion mutants in P. aeruginosa strains PAO1 and PA103 were constructed. In comparison with their parent strains, both mutants showed a significant reduction in the level of exotoxin A activity. However, upon extensive subculturing, the level of exotoxin A produced by the PAO1::ptxR mutant was similar to that of PAO1. Transcriptional studies, using both toxA-lacZ fusion and RNA analysis, confirmed that ptxR increases toxA and regA transcription. These results suggest that ptxR regulates (through regA) exotoxin A production at the transcriptional level.

Nanosecond-pulsed spark discharge plasma in liquid nitrogen: synthesis of polynitrogen from NaN 3 (2019)

Abstract Nanosecond-pulsed plasma ignited in liquid nitrogen is a unique tool for the synthesis of unconventional materials due to a combination of energetic properties of the discharge itself (high densities of reactive species, pressures and radiation) with the low temperature of the surrounding dense liquid. Here, we report on applications of such plasma for synthesis of a polymeric nitrogen compound, preliminarily identified as neutral or ionic N 6 , from sodium azide precursors.
Collision-free coordination of a group of unicycle mobile robots (2009)

We propose a method for collision-free coordination of a group of unicycle mobile robots. A supervisory system assigns to each robot its reference path, together with the desired velocity profile as a function of the position along the path. While the collisions of the robots are not acceptable, the reference paths and velocity profiles do not necessarily prevent the collisions. Feedback controllers of individual robots coordinate their motions along the assigned paths such as to ensure collision-free movements. These controllers realize globally asymptotic stable tracking of the reference trajectories under constraints on the actuator inputs. The controllers proposed here offer several advantages with respect to those in the literature, such as better suppression of tracking errors due to more freedom in controller tuning and relaxed constraints on the reference velocities. The coordination method and the feedback control design have been successfully validated in experiments. These ca be used for the realization of autonomous transportation tasks in warehouses, harbors, factories, etc.

Effects of the increase of side erase band width on off-track capability of high frequency magnetic recording (1996)

Method of measuring side erase band width with a spinstand has been improved using narrow-band overwrite filter read-back track profile, which provides a sharp vertex and two straight side lines. The resultant measurements are in good agreement with those obtained from '747' tests. Effects of the increase of the side erase band width caused from high frequency magnetic recording has been investigated. The impact on the off-track capability due to increase of side erase band width of high frequency magnetic recording is discussed.
An Improved Cu-Based Catalyst System for the Reactions of Alcohols with Aryl Halides (2007)

The use of 3,4,7,8-tetramethyl-1,10-phenanthroline (Me(4)Phen) as a ligand improves the Cu-catalyzed cross-coupling reactions of aryl iodides and bromides with primary and secondary aliphatic, benzylic, allylic, and propargylic alcohols. Most importantly, by employing this catalyst system, the need to use an excessive quantity of the alcohol coupling partner is alleviated. The relatively mild conditions, short reaction times, and moderately low catalyst loading allow for a wide array of functional groups to be tolerated on both the electrophilic and nucleophilic coupling partners.
Efeito da farinha da casca de maracujá no peso e no índice glicêmico de ratos (2014)

The fiber intake isan alternative to weight control. The objective of this experiment was to determine the effect of pectin, present in passion fruit peel, on weight change and glucose. Have been used 35 male Wistar rats divided into four groups. The Control group received water and food (n=09); The passion fruit group received food plus passion fruit peel (n=09); The hyper caloric group received cafeteria diet (n=08); The hyper caloric+ passion fruit group received caloric diet increased with passion fruit peel (n=09), over 21 days. The weight of the animals was measured once a week and blood glucose was measured in the first week and at the end of the experiment. The difference in weight was analyzed with ANOVA, a criterion, followed by Bonferroni’s test; was adopted significance level of 5% (p&lt;0.05). Was observed reduction in weight gain in the passion fruit group in comparison with the control group and increased weight gain in the hyper caloric and hypercaloric+passion fruit groups, between the beginning of the experiment and the 1st week of treatment. Between the 2nd and 3rd week of treatment, the hyper caloric grouph adan increase in body weight compared witht he other groups. The weight gain in the passion fruit group and hypercaloric+passion fruit group did not differ from the control group. The glycemia (mg/dl) at the end of the experiment was higher in hyper caloric and hyper caloric+passion fruit group than in the control and passion fruit groups. We conclude that the passion fruit peel flour associated with hyper caloric diet reduced weight gain, but insufficient to reduce glycemia.
Investigation of Polyimidesiloxanes for Use as Adhesives by Electron Spectroscopy for Chemical Analysis (1997)

Abstract Angle-dependent electron spectroscopy for chemical analysis (ESCA) was used to examine the air facing surface (20–100 Å thick) composition of polyimidesiloxanes with different processing variations, and of varying polydimethylsiloxane (PDMS) content and block length (number of PDMS repeat unit varies from 1 to 9). Polyimide was clearly detected (due to the nitrogen content) in the 20–100 Å surface regions. This shows that a small amount of PDMS and short PDMS segment lengths in polyimidesiloxanes give a surface region with both PDMS and polyimide present. The surface composition, particularly that in the ca. 100 Å region, was correlated to the peel strength of polyimidesiloxane melt pressed to a metal substrate. Our results suggest that both PDMS and polyimide are essential components to rendering a needed peel strength. PDMS, having a good diffusive ability, readily reaches the substrate upon being pressed, achieving intimate contact, while imide groups interact with the substrate, presumably through chemical bonding; these two factors act synergistically to result in a high peel strength. In addition, the interaction mechanism and the failure mechanism involved in bonding polyimidesiloxane and metal substrate were also elucidated based on the ESCA results.
