Maximal Acceptable Ghost Images for Designing a Legible Windshield-Type Vehicle Head-Up Display (2017)

Windshield-type vehicle head-up displays (HUDs) are increasingly popular and stepping forward augmented reality; however, the windshield causes an annoying problem-ghost images. By now, the maximal extent of ghost images has not been determined for an HUD with an acceptable legibility. In this paper, to find the quantitative criterion of ghost images regarding subjective perceptions, we first design an HUD using a rotatable aspheric reflector and a wedge-glass windshield. Optical design of the HUD and experimental results of high-quality images are discussed. Next, eight different disparity angles between the primary and ghost images are controllably generated by rotating the aspheric reflector. Based on this HUD platform, human factor experiments utilizing a simulative automotive driving environment are conducted, in which the eight disparity angles are provided to 12 subjects under three ambient contrast ratios (ACRs). The human factor experiments demonstrate that the maximal disparity angles for an acceptable legibility under the ACRs of 3.90, 2.49, and 1.80 are 0.006°, 0.017°, and 0.024°, respectively. These maximal acceptable disparity angles are important references for quantitatively and efficiently evaluating the optomechanical system of an HUD. In addition, they can help to make vehicle laws and regulations for HUDs.

Cell cycle-mediated structural and functional alteration of P85gag-mos protein kinase activity. (1990)

We investigated cell cycle-dependent regulation of protein kinase activity encoded by the viral mos gene by using a normal rat kidney cell line (NRK-6m2) chronically infected with a temperature-sensitive mutant (ts110) of Moloney murine sarcoma virus, which produces the P85gag-mos transforming protein. In elutriation experiments, in which cells in various phases of the cell cycle are separated based upon size, a twofold increase in the specific activity of the P85gag-mos protein kinase was observed as cells progressed from G0/G1 through S and G2/M. A three- to fourfold increase in gas-mos protein kinase specific activity relative to unsynchronized cells was observed in mitotic NRK-6m2 cells synchronized by treatment with thymidine followed by colcemid or with nocodazole alone. Interestingly, the gag-mos protein was structurally altered in mitotic cells generating a protein species moving slower than P85gag-mos in SDS-polyacrylamide gels. Our findings indicate that viral mos protein kinase activity is regulated during the cell cycle via phosphorylation. We propose that the mos transforming protein functions in a pleiotropic manner, affecting both cytoplasmic and nuclear targets.
PRICING OPTIONS FROM THE POINT OF VIEW OF A TRADER (2006)

This paper is a contribution to the pricing and hedging of options in a market where the volatility is stochastic. The new concept of relative indifference pricing is further developed. This relative price is the price at which an option trader is indifferent to trade in an additional option, given that he is currently holding and dynamically hedging a portfolio of options. We find that the appropriate volatility risk premium depends on the trader's risk aversion coefficient and his portfolio position before selling or buying the additional option. We suggest two asymptotic expansions which relate the volatility risk premium to the Vega of the option portfolio. This approach provides a tool for traders to (i) integrate option pricing with risk management and (ii) quote competitive prices that depend on their aggregate risk exposure.
Disruption of Thermal Perception in a Multiple Sclerosis Patient With Central Pain (2002)

The absence of thermal grill-evoked pain is consistent with the hypothesis that in some cases of central pain the loss of the thermosensory pathway results in disruption of the normal cold inhibition of burning pain.

Dynamic flight modeling of a multi-mode flying wing quadrotor aircraft (2013)

As the demand for versatile and efficient aerial vehicles increases, the limits of current aerial vehicles become more apparent. There is a necessity for autonomous unmanned aerial vehicles (UAVs) which can execute tasks that no manned aircraft has the ability to perform. This paper focuses on vertical take off and landing (VTOL) hybrids, a category of UAVs that encompasses features from both VTOL rotorcraft and fixed-wing aircraft. While there is a multitude of unique UAVs that can perform specific tasks, an effective autonomous UAV is one that retains the versatility of VTOL and the efficiency of a winged aircraft. The research presented demonstrates the navigation, guidance, and transition modeling of a VTOL hybrid. The research presented focuses heavily on the future of navigation models concerning this vehicle, where the full potential of a VTOL hybrid will be most useful in real world situations. The models developed are low fidelity to focus on the development of a navigation algorithm.

The Reduction of Zinc using Goethite Process and Adsorption of Pb+II, Cu+II and Cr+III on Selected Precipitate (2011)

This paper deals with the problem of waste sludge from the production of zinc chloride in the company Bochemie. This sludge contains a high degree of zinc (therefore it cannot be used to charge a blast furnace) and a significant amount of dangerous waste is created. Waste sludge was treated under laboratory conditions, using the goethite precipitation process. Selected ferro-precipitate was used as immobilization agent for removing heavy metals from aqueous solutions. Lead, cooper and chromium were used as model metals. The simultaneous measurements of the heavy metals adsorption and zeta potential determination of the (adsorption) suspensions were carried out. The adsorption isotherms were found to be of typical Langmuir type; values of the heavy metals adsorption capacities have been calculated (a m = 0.76 mmol/ g for lead, 0.58 mmol/g for cooper, 0.38 mmol/ g for chromium, respectively). Shape of the adsorption isotherms was correlated with zeta potential values at the adsorption equilibrium. Addition of the heavy metals ions affects the value of -potential, making the zeta potential values more positive.
Alpha‐Klotho, a critical protein for lung health, is not expressed in normal lung (2019)

Alpha-Klotho (αKlotho), produced by the kidney and selected organs, is essential for tissue maintenance and protection. Homozygous αKlotho-deficiency leads to premature multi-organ degeneration and death; heterozygous insufficiency leads to apoptosis, oxidative stress, and increased injury susceptibility. There is inconsistent data in the literature regarding whether αKlotho is produced locally in the lung or derived from circulation. We probed murine and human lung by immunohistochemistry (IHC) and immunoblot (IB) using two monoclonal (anti-αKlotho Kl1 and Kl2 domains) and three other common commercial antibodies. Monoclonal anti-Kl1 and anti-Kl2 yielded no labeling in lung on IHC or IB; specific labeling was observed in kidney (positive control) and also murine lungs following tracheal delivery of αKlotho cDNA, demonstrating specificity and ability to detect artificial pulmonary expression. Other commercial antibodies labeled numerous lung structures (IHC) and multiple bands (IB) incompatible with known αKlotho mobility; labeling was not abolished by blocking with purified αKlotho or using lungs from hypomorphic αKlotho-deficient mice, indicating nonspecificity. Results highlight the need for rigorous validation of reagents. The lung lacks native αKlotho expression and derives full-length αKlotho from circulation; findings could explain susceptibility to lung injury in extrapulmonary pathology associated with reduced circulating αKlotho levels, for example, renal failure. Conversely, αKlotho may be artificially expressed in the lung, suggesting therapeutic opportunities.
The Pair of White Shoes (1950)

M AIss CHUs rapped on the desk for order. girls will wear white dresses, socks and shoes at the May day program. I had no white shoes. Miss Childs said, have worked hard on the Maypole dance and the sixth grade wants to make a good showing. The boys will wear Sunday suits. Miss Childs was fat, short and bug-eyed. Her eyes roamed around the room. They lighted on Martha Andrews who was skinny, had greasy black hair and wrote dirty words in the girls' rest room. Martha, do you have any white shoes? Martha never talked but whined. No, Mam, mama said I'd have to wear black ones. Miss Childs said, P.T.A. has money for shoes. Those who can't afford a pair, bring a note from your mother. We want the program to be nice.
Compact Bilinear Pooling (2015)

Bilinear models has been shown to achieve impressive performance on a wide range of visual tasks, such as semantic segmentation, fine grained recognition and face recognition. However, bilinear features are high dimensional, typically on the order of hundreds of thousands to a few million, which makes them impractical for subsequent analysis. We propose two compact bilinear representations with the same discriminative power as the full bilinear representation but with only a few thousand dimensions. Our compact representations allow back-propagation of classification errors enabling an end-to-end optimization of the visual recognition system. The compact bilinear representations are derived through a novel kernelized analysis of bilinear pooling which provide insights into the discriminative power of bilinear pooling, and a platform for further research in compact pooling methods. Experimentation illustrate the utility of the proposed representations for image classification and few-shot learning across several datasets.

Release Rate of Drugs from Ethyl Cellulose Coated Granules Containing Caffeine and Salicylic Acid (1979)

AbstractFluidized bed coating with ethyl cellulose., polyethylene glycol mixtures has been utilized for prolongation of drug release from granules containing salicylic acid and caffeine as model drugs. Drug release from the coated granules followed first order kinetics.Particle size of the active material, granule composition and extraction medium pH did not affect the rate and kinetics of drug release. Increase in coat thickness decreased the release rate whereas elevation of the ratio of polyethylene glycol to ethyl cellulose enhanced the release rate to a degree related to the polyethylene glycol concentration. The permeability constants of salicylic acid and caffeine for the ethyl cellulose-polyethylene glycol coatings were of a similar order to those measured previously using solutions of the drugs with planar barrier films.

Characterization of ScN heterojunctions (2002)

ScN metal contacts and unintentionally doped n-type ScN with p type Si, and isotype (n-n) ScN and GaN junctions are fabricated and tested. ScN films grown by plasma assisted physical vapor deposition (PAPVD) and RF-sputtering show the carrier concentration for intrinsic ScN to be between 10/sup 14/-10/sup 16/ cm/sup -3/. Values for unintentionally and intentionally doped n-type films range from 10/sup 17/ to 10/sup 20/ cm/sup -3/, and for intentionally doped (Mg) p-type from 10/sup 15/ to 10/sup 17/ cm/sup -3/. Metal contacts (Pd, Ni, Ti) are dc-sputtered on the ScN films. For the n-type PAPVD ScN, the best ohmic contact is Ti, with the contact resistance in the range 10/sup 3/ Ohm; Pd and Ni contacts are similar to Ti. For the n-type sputtered films, the best ohmic contact is Pd with resistance in the tens of Ohms range. Ti forms ohmic contacts with slightly higher resistance than Pd. Ni contacts have resistance in the range 10/sup 3/ Ohm. Both PAPVD and sputtered unintentionally doped n-type ScN show rectifying behavior with p-Si. The leakage current is less than 10/sup -5/ A at -4 V when temperature is 260-300 K. The leakage current is found to slightly increase at 340 K while the forward current drops. The turn-on voltage for this junction is found to be in the range 1.12-1.45 V. ScN/GaN isotype (n-n) heterojunctions display rectifying behavior with turn on voltages between 0.57 V and 1.25 V and leakage current at -4 V in the range of 10/sup -5/ A.
Apoptosis of astrocytes with enhanced lysosomal activity and oligodendrocytes in white matter lesions in Alzheimer's disease (2002)

Cerebral white matter lesions in Alzheimer's disease (AD) consist of subcortical degeneration and ischaemic-hypoxic changes. Glial changes are intimately associated with the white matter lesions, and regressive changes in astrocytes and loss of oligodendroglial cells have been reported. We quantitatively compared glial changes including apoptosis and enhanced lysosomal activity in the frontal and temporal white matter by using terminal dUTP nick end labelling (TUNEL) and immunohistochemistry for glial markers, lysosomes and apoptosis-regulating proteins in non-familial AD brains. The degree of myelin pallor and axonal loss varied considerably in both the frontal and temporal white matter but fibrillary gliosis in demyelinated lesions tended to be less prominent in the temporal white matter in AD cases. A morphometric study with planimetric methods for cross-sectional areas of frontal and temporal white matter revealed that the white matter of AD cases manifested atrophy with significant reduction in frontal (11.9%) and temporal (29.4%) white matter compared to normal controls. Double immunolabelling for glial fibrillary acidic protein (GFAP) and KP1 (CD68) revealed KP1-positive fragmented structures within the weakly GFAP-labelled astrocytes. These KP1-positive structures correspond to process fragmentation and cytoplasmic vacuoles, which in turn indicate enhanced lysosomal activity during regressive changes in astrocytes. The KP1-modified astrocytes were not found in Pick's disease and corticobasal degeneration. The density of apoptotic glial cells, largely oligodendroglial, was significantly higher in the temporal than in the frontal white matter, and most GFAP-positive astrocytes with regressive changes were apoptotic. GFAP-positive astrocyte density was statistically the same in the frontal and temporal white matter, but the density of KP1-modified astrocytes was higher in the temporal than in the frontal white matter. The rate of white matter shrinkage was significantly correlated with the density of apoptotic glial cells and the density of KP1-modified astrocytes in the temporal lobe in AD cases. An increase in apoptotic glial cell density was found to contribute to GFAP-positive astrocytes with regressive changes in temporal white matter, while apoptosis of vascular smooth muscle cells did not show topographical accentuation. Astrocytes labelled with beta amyloid protein were not apoptotic, and the density of apoptotic cells labelled with CD95 and caspase-3 was too low in both types of white matter to be statistically evaluated. Our results imply that regressive changes in astrocytes and glial apoptosis are, to some extent, associated with white matter lesions, particularly of the temporal lobe in AD brains. The presence of apoptotic astrocytes with evidence of regressive change could therefore be a histological hallmark for white matter degeneration in AD.
Molecular Identification of Cytosolic, Patatin-Related Phospholipases A from Arabidopsis with Potential Functions in Plant Signal Transduction (2002)

Rapid activation of phospholipase A (PLA) by auxin or plant-pathogen interaction suggests a function in signal transduction for this enzyme, but the molecular identification of a cytosolic PLA carrying out this function remains open. We isolated four cDNA sequences from Arabidopsis (ecotype Columbia), AtPLA I, AtPLA IIA, AtPLA IVA, and AtPLA IVC, which are members of the patatin-related PLA gene family in plants and which are homologous to the animal Ca(2+)-independent PLA(2) gene family. Expression was measured by reverse transcriptase-polymerase chain reaction, and AtPLA I transcripts were found preferentially in shoots, AtPLA IIA and AtPLA IVA in roots, and AtPLA IVC in flowers. Transient expression of the four PLA-green fluorescent protein fusion proteins in tobacco (Nicotiana tabacum) leaves showed they were located in the cytosol and not in the vacuoles. Surprisingly, AtPLA::green fluorescent protein was also localized to chloroplasts. The enzymatic activity of the purified recombinant AtPLA IVA toward phosphatidylcholine was dependent on Ca(2+), saturated at 0.5 mM, and had a pH optimum of about 7.0. It had both PLA(1) and PLA(2) specificity. The enzyme showed in vitro highest sensitivity toward the PLA(2) inhibitors palmitoyltrifluoromethyl ketone (PACOCF(3), K(i) approximately 30 nM), arachidonyltrifluoromethyl ketone (AACOCF(3), K(i) approximately 25 microM), and tetrahydro-3-(1-naphtalenyl)-2H-pyran-2-one (K(i) approximately 200 nM) and was also sensitive to other previously used inhibitors 5,8,11,14-eicosatetraynoic acid (K(i) approximately 3 microM) and nordihydroguajaretic acid (K(i) approximately 15 microM). The influence of these PLA(2) inhibitors on elongation in etiolated Arabidopsis seedlings was tested, and tetrahydro-3-(1-naphtalenyl)-2H-pyran-2-one and 5,8,11,14-eicosatetraynoic acid inhibited hypocotyl elongation maximally at concentrations close to their K(i) in vitro.
Diminished levels of nasal S100A7 (psoriasin) in seasonal allergic rhinitis: an effect mediated by Th2 cytokines (2012)

The present study shows an epithelial expression and excretion of S100A7 in the nose after microbial stimulation. The levels are diminished in rhinitis patients and in the presence of an allergic cytokine milieu, suggesting that the antimicrobial defense is compromised in patients with SAR.
Monitoring Pulmonary Function in Asthma and COPD: Point-of-Care Testing (2003)

Despite recent advances in medical technology, monitoring of asthma and COPD has not changed significantly. PFTs continue to be the gold standard for evaluating airway obstruction and/or restriction. Clinical trials that will evaluate outcomes such as decreased number of hospitalizations, emergency department visits, unscheduled visits to physicians, and days absent from school or work are needed to determine the utility of new monitoring technologies.
Improved melt flow and physical properties of Mitsui Toatsu's LARC-TPI 1500 series polyimide (1990)

The basic thermal properties and melt behavior of an improved form of LARC-TPI polyimide, LARC-TPI 1500, are investigated and compared with those of LARC-TPI 1000 and 2000. The LARC-TPI 1500 powders are thermally stable and melt processable. The absolute molecular weight of the polymer varies from 20,000 to 30,000, indicating recurring unit numbers of about 40-60. The melt flow properties of LARC-TPI 1500 are comparable to those of other engineering plastics, such as PEEK, PSU, and PES. The flexural modulus of injection molded parts of LARC-TPI 1500 is the highest among commercial thermoplastic polymers.
Use of Mercury Intrusion Data, Combined with Nitrogen Adsorption Measurements, as a Probe of Pore Network Connectivity (1999)

The coordination number of the pore network of a mesoporous solid can be determined from its nitrogen adsorption and desorption isotherms, using an analysis method based on percolation theory. However, measurement of these isotherms is time-consuming and problematical very close to the bulk condensation pressure of nitrogen. In this paper, we demonstrate that mercury intrusion and nitrogen desorption share the same mechanism so that the mercury intrusion curve can be used in place of the nitrogen desorption isotherm in the connectivity analysis.
