Fully Organic Photocontrolled Deformable Mirror (2018)

Abstract A light‐driven deformable mirror based on an organic photoconductive layer is designed and realized. The requirements for the photoconductive organic material are reported showing their effect on the mirror performances. The production and characterization of the photoconductive thick layer consisting in a polystyrene matrix doped with P3HT:PCBM and an arylamine (4,4′,4″‐tris[phenyl( m ‐tolyl)amino]triphenylamine) are reported. A prototype of the mirror with a clear aperture of 12 mm is built and its performance measured in terms of reflective surface displacement. Moreover, a light valve device based on this mirror is built and characterized.
Receding horizon control of autonomous aerial vehicles (2002)

This paper presents a new approach to trajectory optimization for autonomous fixed-wing aerial vehicles performing large-scale maneuvers. The main result is a planner which designs nearly minimum time planar trajectories to a goal, constrained by no-fly zones and the vehicle's maximum speed and turning rate. Mixed-Integer Linear Programming (MILP) is used for the optimization, and is well suited to trajectory optimization because it can incorporate logical constraints, such as no-fly zone avoidance, and continuous constraints, such as aircraft dynamics. MILP is applied over a receding planning horizon to reduce the computational effort of the planner and to incorporate feedback. In this approach, MILP is used to plan short trajectories that extend towards the goal, but do not necessarily reach it. The cost function accounts for decisions beyond the planning horizon by estimating the time to reach the goal from the plan's end point. This time is estimated by searching a graph representation of the environment. This approach is shown to avoid entrapment behind obstacles, to yield near-optimal performance when comparison with the minimum arrival time found using a fixed horizon controller is possible, and to work consistently on large trajectory optimization problems that are intractable for the fixed horizon controller.
Mn–Zn ferrite with higher magnetization for temperature sensitive magnetic fluid (2003)

A growth-assisted coprecipitation process is proposed to achieve highly magnetic Mn–Zn ferrite particles. In this method, first, the particles were synthesized by coprecipitation under optimum condition. Then, further enhancement in particle size was obtained by using the already prepared particles as seed. The average crystallite size of the particles prepared by the proposed method was 12 nm. Furthermore, the magnetization at 1 T applied field was 50 emu/g compared to 37 emu/g of coprecipitated particles. It should be noted that the Curie temperature of the particles remained similar to the coprecipitated particles suggesting that the composition of the Mn–Zn ferrite particles has not been affected by the modified synthesis technique. The gradient of the magnetization-temperature curve was enhanced as a consequence of the rise in magnetization. These particles could be used for the synthesis of temperature sensitive magnetic fluid with higher magnetization and magnetization-temperature gradient.

Interleukin-5 mRNA levels in blood and bone marrow mononuclear cells from patients with the idiopathic hypereosinophilic syndrome. (1994)

High blood eosinophil counts in humans are usually due to parasitic infections, allergic processes or malignant diseases. Interleukin-5 (IL-5) is thought to be the principal eosinopoietic stimulus in most of these patients. As the causes of persistent eosinophilia in patients with the idiopathic hypereosinophilic syndrome (HES) are (by definition) unknown, a semi-quantitative assay for IL-5 mRNA in eosinophils and mononuclear cells was carried out using samples from 11 patients with HES. In three patients, unstimulated peripheral blood mononuclear cells (PBMC) and bone marrow mononuclear cells (BMMC) had markedly raised levels of IL-5 mRNA. In four of five patients studied, phorbol myristate acetate (PMA) stimulation of PBMC induced them to produce more IL-5 mRNA than four healthy subjects. In five patients, bone marrow IL-5 mRNA levels were related to blood eosinophil counts. Blood eosinophils from all six patients tested, and bone marrow granulocytes from four patients had undetectable levels of IL-5 mRNA. It was concluded that HES can be separated into two groups. One has high levels of IL-5 mRNA and/or an enhanced IL-5 mRNA response to stimulation. They may well respond to treatments which inhibit the effects of this cytokine on eosinophil progenitor cells. The second group appears to have a disease which is IL-5 independent.
Changes in cyclin/proliferating cell nuclear antigen distribution during DNA repair synthesis. (1988)

UV irradiation of quiescent human fibroblasts immediately triggers the appearance of the nuclear protein cyclin/proliferating cell nuclear antigen (PCNA) as detected by indirect immunofluorescent staining after methanol fixation. This was found to be independent of new synthesis of cyclin/PCNA by two-dimensional gel analysis and cycloheximide treatment. The intensity of the immunofluorescent staining of cyclin/PCNA observed in UV-irradiated cells corresponded with the UV dose used and with the DNA repair synthesis detected by autoradiography. The nuclear staining remains as long as DNA repair activity is detected in the cells. By extracting the UV-irradiated quiescent cells with Triton X-100 and fixing with formaldehyde, it was possible to demonstrate by indirect immunofluorescence rapid changes in the cyclin/PCNA population after irradiation, a small proportion (5-10%) of which is tightly associated to the nucleus as determined by high salt extraction. By incubating at low temperature and depleting the ATP pools of the cells before UV irradiation, we have demonstrated that the changes in cyclin/PCNA distribution observed involve at least two different nuclear associations.
Assessment of the proficiency of the surgeon in providing basic and advanced cardiac life support. (1984)

The results of this study demonstrate a need for further improvement in the ability of selected surgeons to manage competently a cardiac arrest according to current AHA guidelines. The importance of formal training is demonstrated by the fact that prior BCLS or ACLS certification increased the likelihood that proper resuscitative measures will be used by the surgeon. In particular, greater emphasis should be placed upon standard dysrhythmia treatment protocols since we have shown that the level of the expertise of the surgeon in this area is lowest. Improvement in resuscitation skills should enhance the ability of the surgeon to treat effectively patients who are critically ill.
EXCESS ENTHALPY AND VAPOR-LIQUID EQUILIBRIA WITH THE MHV2 AND SOAVE MIXING RULES (2011)

Calculations and predictions of excess enthalpy (HE) and vapor-liquid equilibrium (VLE) were performed using the Gibbs energy mixing rules MHV2 and a modification of it by Soave. The Soave-Redlich-Kwong equation of state was combined with the UNIQUAC equation. Four sets of parameters estimated in the UNIQUAC model were used for each of seven binary systems: the first estimated from VLE data, the second and the third estimated from HE data for two versions of the UNIQUAC equation, and the fourth estimated from both HE and VLE data simultaneously. It was found that HE calculations can be performed with the mixing rules; the average relative errors fell from around 200% for the conventional mixing rule to around 60% for MHV2 combined with DECHEMA UNIQUAC parameters and was as little as 20% when the UNIQUAC parameters had been estimated from HE and VLE data simultaneously. However, the approach suffers from the same shortcomings as far as cross-prediction between HE and VLE data is concerned, as does the UNIQUAC equation used alone. There is a discrepancy between values obtained with the mixing rule and those obtained with the UNIQUAC equation directly. This discrepancy is smaller for the Soave modification of the mixing rule.
Interest of the association retinaldehyde/glycolic acid in adult acne (2009)

These data show that a combination of RAL 0.1% and GA 6% may be used in association with other topical anti-acne treatments with an excellent tolerance.
Impact of dietary n−3 FA deficiency on rat bone tissue FA composition (2003)

The effect of dietary n-3 FA deficiency on bone tissue FA composition was evaluated in growing rats. Two mixtures combining hydrogenated coconut oil with safflower oil served as the n-3-deficient dietary treatments and provided two levels of linoleic acid (LA). The n-3 treatments were formulated with added alpha-linolenic acid (LNA) from flaxseed oil (diet LNA) or LNA plus DHA, and both were balanced for LA. This study showed that bone is sensitive to changes in dietary n-3 FA and that DHA is more effective than LNA in maintaining DHA levels in these tissues.
CRB1 is essential for external limiting membrane integrity and photoreceptor morphogenesis in the mammalian retina (2003)

Mutations within the CRB1 gene have been shown to cause human retinal diseases including retinitis pigmentosa and Leber congenital amaurosis. We have recently identified a mouse model, retinal degeneration 8 (rd8) with a single base deletion in the Crb1 gene. This mutation is predicted to cause a frame shift and premature stop codon which truncates the transmembrane and cytoplasmic domain of CRB1. Like in Drosophila crumbs (crb) mutants, staining for adherens junction proteins known to localize to the external limiting membrane, the equivalent of the zonula adherens in the mammalian retina, is discontinuous and fragmented. Shortened photoreceptor inner and outer segments are observed as early as 2 weeks after birth, suggesting a developmental defect in these structures rather than a degenerative process. Photoreceptor degeneration is observed only within regions of retinal spotting, which is seen predominantly in the inferior nasal quadrant of the eye, and is caused by retinal folds and pseudorosettes. Photoreceptor dysplasia and degeneration in Crb1 mutants strongly vary with genetic background, suggesting that the variability in phenotypes of human patients that carry mutations in CRB1 may be due to interactions with background modifiers in addition to allelic variations. The Crb1rd8 mouse model will facilitate the analysis of Crb1 function in the neural retina and the identification of interacting factors as candidate retinal disease genes.
Synthesis by enzymatic catalysis. IV. Transesterification of n‐acetyl‐L‐tyrosine ethyl ester with α‐chymotrypsin in water—hexanol—aot micelles (1988)

Abstract A new type of microemulsion system (Aerosol‐OT, water, hexanol) was used to entrap an enzyme (α‐chymotrypsin) in a reverse micelle. N‐acetyl L ‐tyrosine ethyl ester can be solubilised in this medium to give N ‐acetyl L ‐tyrosine hexyl ester in a good yield (80%). This is the first report of a successful enzymatic transesterification in a micellar medium.
Ferrous Centers Confined on Core–Shell Nanostructures for Low-Temperature CO Oxidation (2012)

A noble metal (NM) can stabilize monolayer-dispersed surface oxide phases with metastable nature. The formed "oxide-on-metal" inverse catalyst presents better catalytic performance than the NM because of the introduction of coordinatively unsaturated cations at the oxide-metal boundaries. Here we demonstrate that an ultrathin NM layer grown on a non-NM core can impose the same constraint on the supported oxide as the bulk NM. Cu@Pt core-shell nanoparticles (NPs) decorated with FeO patches use much less Pt but exhibit performance similar to that of Pt NPs covered with surface FeO patches in the catalytic oxidation of CO. The "oxide-on-core@shell" inverse catalyst system may open a new avenue for the design of advanced nanocatalysts with decreased usage of noble metals.

Application of intelligent methods to automotive assembly planning (2007)

The automotive manufacturing process is one of the most complex processes in industry today. The rapid changes in the marketplace and introduction of new technologies require that the underlying manufacturing processes keep pace. The use of intelligent systems for this environment is quickly becoming a necessity. In this paper, we describe how some of these intelligent methods are used at Ford Motor Company in the automotive assembly planning domain. The following applications of intelligent systems will be described: knowledge-based labor management, ergonomics analysis, and workcell layout optimization. We will also discuss how natural language processing can assist in understanding unstructured textual data. All of these examples show how computational intelligence can be successfully applied in an industrial setting.
Nighttime chemical evolution of aerosol and trace gases in a power plant plume: Implications for secondary organic nitrate and organosulfate aerosol formation, NO3 radical chemistry, and N2O5 heterogeneous hydrolysis (2010)

Nighttime chemical evolution of aerosol and trace gases in a coal‐fired power plant plume was monitored with the Department of Energy Grumman Gulfstream‐1 aircraft during the 2002 New England Air Quality Study field campaign. Quasi‐Lagrangian sampling in the plume at increasing downwind distances and processing times was guided by a constant‐volume balloon that was released near the power plant at sunset. While no evidence of fly ash particles was found, concentrations of particulate organics, sulfate, and nitrate were higher in the plume than in the background air. The enhanced sulfate concentrations were attributed to direct emissions of gaseous H 2 SO 4 , some of which had formed new particles as evidenced by enhanced concentrations of nucleation‐mode particles in the plume. The aerosol species were internally mixed and the particles were acidic, suggesting that particulate nitrate was in the form of organic nitrate. The enhanced particulate organic and nitrate masses in the plume were inferred as secondary organic aerosol, which was possibly formed from NO 3 radical‐initiated oxidation of isoprene and other trace organic gases in the presence of acidic sulfate particles. Microspectroscopic analysis of particle samples suggested that some sulfate was in the form of organosulfates. Microspectroscopy also revealed the presence of sp 2 hybridized C = C bonds, which decreased with increasing processing time in the plume, possibly because of heterogeneous chemistry on particulate organics. Constrained plume modeling analysis of the aircraft and tetroon observations showed that heterogeneous hydrolysis of N 2 O 5 was negligibly slow. These results have significant implications for several issues related to the impacts of power plant emissions on air quality and climate.

Acute protective effects of different doses of simvastatin in the rat model of renal ischemia-reperfusion injury (2008)

It was previously shown that acute pretreatment with simvastatin (1 mg/kg) significantly protects rats from renal ischemia-reperfusion injury (I/R, 45 min + 4 h). The aim of our present study was to determine whether this beneficial effect of simvastatin was dose-related. A single dose of simvastatin of 1 or 3 mg/kg, i.v. bolus, dissolved in 10% DMSO (Sim1 and Sim3), was injected 30 min before ischemia, 30 min before reperfusion or 5 min before reperfusion (30I, 30R, and 5R, respectively). Simvastatin-treated rats were compared to the appropriate controls (I/R + DMSO and Sham + DMSO group). Sim1 and Sim3 groups were similar regarding serum concentrations of urea, creatinine, aspartate aminotransferase, and gamma-glutamiltransferase (sUr, sCre, ALT, and γGT, respectively), as well as total histological score. Both doses of the drug (Sim1 and Sim3) were more effective in the reduction of total histological score in comparison with I/R + DMSO group. Also, the higher dose of drug 3 mg/kg (Sim3) was somewhat more effective than Sim1 in the reduction of tubular necrosis score and loss of brush border. In conclusion, the acute protective effect of simvastatin in the experimental model of renal I/R injury does not seem to be dose-related, and the dose of 1 mg/kg should be chosen for further investigation.
Primitive sex chromosomes in poeciliid fishes harbor simple repetitive DNA sequences (1993)

The demonstration of the chromosomal mode of sex determination via genetic experiments as well as the absence of heteromorphic sex chromosomes affirm poeciliid fishes as a unique group among vertebrates that are endowed with the most primitive form of sex chromosomes. In many different taxa the evolutionary process involved in the differentiation of advanced sex chromosomes is outlined through sex specifically organized repetitive sequences. In this investigation hybridization of synthetic probes specific to genomic simple repeat motifs uncovers a sex-specific hybridization pattern in certain viviparous fishes of the family Poeciliidae. The hybridization pattern together with specific staining of the constitutive heterochromatin by C-banding reveals heterogamety in males (Poecilia reticulata) as well as in females (P. sphenops). In P. velifera, however, C-banding alone fails to unravel the heterogametic status. The female specific W-chromosome can be detected by simple repetitive sequence probes. Therefore, the principal significance of heterochromatization as a means of generating differentiated sex chromosomes is evident.

Sampling design for Gaussian detection problems (1997)

We propose an approach for the design of sampling schemes for Gaussian hypothesis testing problems. Our approach for this design is based on the class of Ali-Silvey (see J. Royal Stat. Soc., Series B, vol.28, p.131-43, 1996) distance measures. Closed forms for the Bhattacharyya distance, the I-divergence, the J-divergence, and the Chernoff distance between the class conditional densities are obtained for the sampling design problem in the strong signal case. A new member of the class of Ali-Silvey distance measures that is suitable for the detection problem in the weak signal case is also derived. Sampling schemes are determined to maximize those four distance measures as well as the new distance measure for the strong signal case and the weak signal case, respectively. The detection performance of our sampling schemes is compared with those of various other sampling schemes by means of numerical examples. Comparisons show that the sampling design based on Ali-Silvey distance measures result in superior performance.
Parameter identification of modified Bouc–Wen model and analysis of size effect of magnetorheological dampers (2017)

Magnetorheological damper is one of the most promising smart devices for vibration mitigation of structures subjected to dynamic loads. In order to fulfill the value of magnetorheological damping control, a feasible mechanical model of magnetorheological dampers with simplicity and sufficient accuracy is usually required in practice. It comes up, however, with a challenging issue for the modeling of large-size magnetorheological dampers due to physical constraints on the performance test. The large-size magnetorheological damper is typically modeled in up-scaling parameters associated with models of the small-size magnetorheological damper. This treatment remains open since a size effect hinges upon the intrinsic non-linearity inherent in the device. In this article, a dynamic test of a small-size magnetorheological damper is performed first. The relevance of damper force with the input current and excitation frequency is well revealed. The modified Bouc–Wen model is employed to logically represent the dynamic behaviors of magnetorheological dampers. Identification of model parameters in typical loading cases is then proceeded, of which the functional relationship against input current is established. The size effect of magnetorheological dampers is further addressed through investigating the functional relationship relevant to maximum outputs of 200, 10, and 5 kN. It is indicated that the small-size magnetorheological damper needs more number of control parameters than the large-size magnetorheological damper. Moreover, a linear current relevance of model parameters appears in the small-size magnetorheological damper, while a quadratic current relevance of model parameters appears in the large-size magnetorheological damper. Size effect of magnetorheological dampers arises to be well-marked in the range of low current and becomes unapparent in the range of high current. Besides, the validation of modified Bouc–Wen model is carried out that reveals the applicability of the model with case-optimized parameters.
