Abstract : The problem of transferring alignment between two airborne inertial navigator platforms is treated using the Kalman filter approach. The important parameters are identified and exercised over a reasonable range to establish accuracy trade-offs. Suggestions are provided for improving the accuracy of Kalman filter transfer alignment through more complex maneuvers of the carrying aircraft.
Real-time individualized virtual humans (2008)

This tutorial will present the latest techniques to model fast individualized animatable virtual humans for Real-Time applications. As a human is composed of a head and a body, we will analyze how these two parts can be modeled and globally animated as in real-life. More precisely, we will show how we can model and deform human bodies and heads. Facial animation will be also addressed from motion facial capture and voice to the simulation of interactive realistic talking virtual humans, including personality models and complete body gestures. We will describe how we can model crowds in realtime using dynamic meshes, static meshes and impostors. Techniques to introduce variety in crowds including individual animation with accessories will be explained.
Dual-wavelength phosphorimetry for determination of cortical and subcortical microvascular oxygenation in rat kidney (2005)

This study presents a dual-wavelength phosphorimeter developed to measure microvascular PO2 (microPO2) in different depths in tissue and demonstrates its use in rat kidney. The used phosphorescent dye is Oxyphor G2 with excitation bands at 440 and 632 nm. The broad spectral gap between the excitation bands combined with a relatively low light absorption of 632 nm light by tissue results in a marked difference in penetration depths of both excitation wavelengths. In rat kidney, we determine the catchments depth of the 440-nm excitation to be 700 microm, whereas the catchments depth of 632 nm is as much as 4 mm. Therefore, the measurements differentiate between cortex and outer medulla, respectively. In vitro, no difference in PO2 readings between both channels was found. On the rat kidney in vivo, the measured cortical microPO2 was on average 20 Torr higher than the medullary microPO2 over a wide PO2 range induced by variations in inspired oxygen fraction. Examples provided from endotoxemia and resuscitation show differences in responses of mean cortical and medullary PO2 readings as well as in the shape of the PO2 histograms. It can be concluded that oxygen-dependent quenching of phosphorescence of Oxyphor G2 allows quantitative measurement of microPO2 noninvasively in two different depths in vivo. Oxygen levels measured by this technique in the rat renal cortex and outer medulla are consistent with previously published values detected by Clark-type oxygen electrodes. Dual-wavelength phosphorimetry is excellently suited for monitoring microPO2 changes in two different anatomical layers under pathophysiological conditions with the characteristics of providing oxygen histograms from two depths and having a penetration depth of several millimeters.

Subband image representation employing wavelets and multi-transforms (2005)

In this paper, a technique is proposed for the efficient representation of 2-D images employing the wavelet transform and the multi-transform technique. The 2-D wavelet transform is first applied to perform a subband decomposition of the image spectrum on a logarithmic scale. The multi-transforms are then independently applied to each of the subbands. Specifically the DCT and the Haar transforms are considered in a parallel implementation. The algorithm efficiently represents each subband as combination of the Haar and DCT coefficients. These subbands are then combined to reconstruct the original image. The RMSE variation is analyzed for a monochrome image as a function of the number of retained coefficients. This is compared with results obtained employing a single transform, in conjunction with identical subbanding.

Multiple database integration in CALIDA: design and implementation (2002)

The authors discuss the issues of integration of multiple heterogeneous databases and describe a system called CALIDA, developed to access corporate data from relational databases, variable-record-type files, and flat files. The database integration model used in CALIDA contains three levels: the conceptual or language level, the logical or schema level, and physical or data level. The conceptual framework for database integration proposed in CALIDA covers a variety of heterogeneous databases. CALIDA is implemented in Interlisp-D on a Xerox 1186 workstation and accesses remote IBM mainframe resident databases via a wide-area network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optical Band Gap of Barium Titanate Nanoparticles Prepared by RF-plasma Chemical Vapor Deposition (2005)

The size dependence of the band gap for barium titanate nanoparticles prepared by RF-plasma chemical vapor deposition was investigated by measuring the diffuse reflectance spectra. The band gap of the indirect transition gradually increased, as the particle sizes decreased to less than 11.5 nm. Consequently, the band gap for particles of 6.7 nm in size was measured to be 3.47 eV, which was approximately 0.25 eV larger than that of BaTiO 3 bulk. This phenomenon was discussed on the basis of quantum confinement model.
Synthesis and biological activity of novel calcium channel blockers: 2,5-dihydro-4-methyl-2-phenyl-1,5-benzothiazepine-3-carboxylic acid esters and 2,5-dihydro-4-methyl-2-phenyl-1,5-benzodiazepine-3-carboxylic acid esters (1987)

2,5-Dihydro-4-methyl-2-phenyl-1,5-benzothiazepine-3-carboxylic acid esters, based on the structures of dihydropyridines and diltiazem, were synthesized from o-aminothiophenol and 2-(phenylmethylene)- 3-oxobutanoic acid esters. Biological evaluation in the potassium-depolarized rabbit aorta suggests that these compounds are calcium channel blockers. The in vitro activity was further confirmed by electrophysiological techniques. Structure-activity studies for the aromatic substitution showed that the 2-nitro derivative was the most potent (IC50 = 0.3 microM) compound in vitro while the ethyl ester was slightly better than the corresponding methyl ester. Replacement of sulfur with nitrogen atom provided 2,5-dihydro-4-methyl-2-(3-nitrophenyl)-1,5-benzodiazepine-3-carboxylic acid ethyl ester, which was only slightly less active than the corresponding benzothiazepine. Derivatization of the nitrogen in 2,5-dihydro-4-methyl- 2-(3-nitrophenyl)-1,5-benzothiazepine-3-carboxylic acid methyl ester with a (dimethylamino)ethyl group (present in diltiazem) provided 2,5-dihydro-5-[(dimethylamino)ethyl]- 4-methyl-2-(3-nitrophenyl)-1,5-benzo-thiazepine-3-carboxylic acid methyl ester, which was found to be equipotent to diltiazem in vitro. Radioligand binding studies using [3H]nitrendipine and [3H]diltiazem showed that the compound with the free nitrogen binds competitively into the dihydropyridine binding site while the molecule in which the nitrogen is alkylated with a (dimethylamino)ethyl group interacts competitively with both diltiazem and dihydropyridine binding sites. Our results therefore show that 2,5-dihydro-4-methyl-2-phenyl-1,5-benzothiazepine-3-carboxylic ester is a good starting point for designing dihydropyridine as well as diltiazem mimics.

Pancreatic acinar AR42J cells express functional nerve growth factor receptors (1999)

The factors regulating the differentiation of the endocrine cells of the pancreas are still unknown. In previous studies, we have demonstrated that, like neurones, various beta-cell lines express functional neurotrophin receptors. Moreover, Trk-A, the nerve growth factor (NGF) high-affinity receptor, is expressed in vivo in mature rat islets and early during development in the pancreatic ductal network that represents the source of putative stem cells. Rat pancreatic AR42J cells possess both exocrine and neuroendocrine properties. Recent studies have shown that these cells can differentiate either into acinar cells or into insulin-expressing cells. In this study, we demonstrate that AR42J cells, in common with the embryonic ductal cells, do express Trk-A. Moreover, on treatment with NGF, Trk-A is phosphorylated and early responsive genes such as NGFI-A, c-fos and c-jun are induced. These results clearly show that the Trk-A receptor expressed in AR42J is functional. AR42J cells provide a model system with which to study the role of NGF in the development of the pancreatic cells.
Science supporting the economic and environmental benefits of using wood and wood products in green building construction (2016)

The objective of this report is to summarize the scientific findings that support the environmental and economic benefits of using wood and wood products in green building construction. Despite documented advantages in many peer-reviewed scientific articles, most building professionals and members of the public do not recognize wood as a renewable resource or the role that efficient wood utilization plays in mitigating climate change and promoting healthy forests. Research and development of wood products and building systems also are lagging behind that of other materials. Both scientific advancement in the areas of life cycle analysis and development of new technologies for improved and extended wood utilization are needed to continue to advance wood as a green construction material. We provide three research and technology transfer recommendations that will allow USDA to help to achieve its climate change objectives while creating jobs, bolstering the competitive position and long-term economic stability of the industry, and reducing U.S. dependence on foreign oil.

Miller factor for gate-level coupling delay calculation (2000)

In coupling delay computation, a Miller factor of more than 2/spl times/ may be necessary to account for active coupling capacitance when modeling the delay of deep submicron circuitry in the presence of active coupling capacitance. We propose an efficient method to estimate this factor such that the delay response of a decoupling circuit model can emulate the original coupling circuit. Under the assumptions of zero initial voltage, equal charge transfer, and 0.5V/sub DD/ as the switching threshold voltage, an upper bound of 3/spl times/ for maximum delay and a lower bound of -1/spl times/ for minimum delay can be proven. Efficient Newton-Raphson iteration is also proposed as a technique for computing the Miller factor or effective capacitance. This result is highly applicable to crosstalk coupling delay calculation in deep submicron gate-level static timing analysis. Detailed analysis and approximation are presented. SPICE simulations are demonstrated to show high correlation with these approximations.
[20-Hydroxyecdysone--plant adaptogen: an anabolic effect, possible use in sports nutrition]. (2013)

In the review the presentation about plant adaptogens--biologically active compounds is given. Its administration can help to achieve non-specific state of high resistance. The hypothetical mechanism of action: adaptogens are prostressors, reducing excessive increase of stress mediators in the following stress exposure. The features of adaptogenic effect of phytoecdysteroids, polyhydroxylated sterols, which are analogs of hormones of molting and metamorphosis of arthropodas, and are structurally similar to glucocorticoids on the example of the most widely studied phytoecdysteroid--20-hydroxyecdysone--are described. The results of studies of anabolic action of 20-hydroxyecdysone in experiments on laboratory animals and the possible explanation (existing in the modern scientific literature) of the mechanism of this phenomenon are discussed. Scientific publication testifying on the application of phytoecdysteroids to remove chronic fatigue syndrome, reducing nerve and muscle fatigue, improve memory and attention processes are presented. The prospects of using the 20-hydroxyecdysone in the composition of food supplements and specialized products for athletes are discussed.
Simulators for formal languages, automata and theory of computation with focus on JFLAP (2013)

This report discusses simulators in automata theory and which one should be best for use in laboratory assignments. Currently, the Formal Languages, Automata and Theory of Computation course (FABER) at Mälardalen University uses the JFLAP simulator for extra exercises. To see if any other simulators would be useful either along with JFLAP or standalone, tests were made with nine programs that are able to graphically simulate automata and formal languages. This thesis work started by making an overview of simulators currently available.After the reviews it has become clear to the author that JFLAP is the best choice for majority of cases. JFLAP is also the most popular simulator in automata theory courses worldwide.To support the use of JFLAP for the course a manual and course assignments are created to help the student to getting started with JFLAP. The assignments are expected to replace the current material in the FABER course and to help the uninitiated user to get more out of JFLAP.
Triggering Dectin-1-Pathway Alone Is Not Sufficient to Induce Cytokine Production by Murine Macrophages (2016)

β-glucans (BG) are abundant polysaccharides of the Saccharomyces cerevisiae cell wall (Sc CW), an industry byproduct. They have immuno-stimulatory properties upon engagement of dectin-1 (Clec7a), their main receptor on particular immune cells, and they actually become of great interest because of their preventive or therapeutic potentials. Zymosan, a crude extract of Sc CW was studied as a prototypic BG, despite its miscellaneous PAMPs content. Here, we examined the response of murine wild type or Clec7a-/- bone marrow-derived macrophages (BMDM) to products with increasing BG content (15, 65 or 75%) and compared their effects with those of other dectin-1 ligands. The enrichment process removed TLR ligands while preserving dectin-1 activity. The most enriched extracts have very low NFκB activity and triggered low amounts of cytokine production in contrast with crude products like zymosan and BG15. Furthermore, MyD88-/- BMDM did not produce TNFα in response to crude Sc CW extracts, whereas their response to BG-enriched extracts was unaffected, suggesting that BG alone are not able to initiate cytokine secretion. Although Sc CW-derived BG stimulated the late and strong expression of Csf2 in a dectin-1-dependent manner, they remain poor inducers of chemokine and cytokine production in murine macrophages.
Photoreactions of <i>N</i>-Methyl-1,8-naphthalimide with Methylbenzenes: [3+3]-Additions and Water-Incorporated Additions (1999)

Abstract Novel [3+3]-additions and water (methanol)-incorporated additions were observed in the photoreactions of N-methyl-1,8-naphthalimide with methylbenzenes, such as xylenes, mesitylene, and durene, in acetonitrile. A mechanism for the reactions is proposed on the basis of the fluorescence quenching examinations, calculations of ΔG associated with the electron transfer, and deuteration studies.
Rho family GTPases (2012)

Rho GTPases comprise a family of molecular switches that control signal transduction pathways in eukaryotic cells. A conformational change induced upon binding GTP promotes an interaction with target (effector) proteins to generate a cellular response. A highly conserved function of Rho GTPases from yeast to humans is to control the actin cytoskeleton, although, in addition, they promote a wide range of other cellular activities. Changes in the actin cytoskeleton drive many dynamic aspects of cell behaviour, including morphogenesis, migration, phagocytosis and cytokinesis, and the dysregulation of Rho GTPases is associated with numerous human diseases and disorders.
Analog VLSI neural networks: implementation issues and examples in optimization and supervised learning (1992)

Time-critical neural network applications that require fully parallel hardware implementations for maximal throughput are considered. The rich array of technologies that are being pursued is surveyed, and the analog CMOS VLSI medium approach is focused on. This medium is messy in that limited dynamic range, offset voltages, and noise sources all reduce precision. The authors examine how neural networks can be directly implemented in analog VLSI, giving examples of approaches that have been pursued to date. Two important application areas are highlighted: optimization, because neural hardware may offer a speed advantage of orders of magnitude over other methods; and supervised learning, because of the widespread use and generality of gradient-descent learning algorithms as applied to feedforward networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Longitudinal study of leukocyte functions in homosexual men seroconverted for HIV: rapid and persistent loss of B cell function after HIV infection (1989)

The early effects of infection with human immunodeficiency virus (HIV) were investigated in homosexual men who had seroconverted for anti-HIV antibodies. Leukocyte functional activities were determined in longitudinally collected peripheral blood mononuclear cell samples. During the first 10 months following seroconversion, anti-CD3 monoclonal antibody-induced T cell proliferation, monocyte accessory function and T helper activity on B cell differentiation in a pokeweed mitogen-driven system were not affected. In contrast, from the moment of seroconversion on, B cells of seroconverted men failed to produce immunoglobulin in the pokeweed mitogen-driven system. This defect was not restored by addition of normal CD4+ T cells. Immunoglobulin synthesis induced by Staphylococcus aureus and interleukin 2 decreased gradually, until it was completely lost 10 months after seroconversion. In addition, proliferation in response to anti-IgM or Staphylococcus aureus by B cells from HIV seroconverted men was decreased. The lack of inducible in vitro B cell activity was not accompanied by elevated spontaneous Ig synthesis by B cells of the seroconverted men. In the second group of men studied during the 2nd year following seroconversion, T helper activity on normal B cell differentiation significantly decreased, whereas anti-CD3-induced T cell proliferation and monocyte accessory function were not significantly affected. Our results demonstrate that in almost all HIV-infected individuals B cell functional defects are the first leukocyte abnormalities observed preceding defects in T helper activity.
Assessment of kininases in rheumatic diseases and the effect of therapeutic agents (1987)

Bradykinin is degraded in human plasma by a carboxypeptidase to yield desArg9-bradykinin (DBK) which is then digested by angiotensin-converting enzyme (ACE) to the pentapeptide Arg-Pro-Pro-Gly-Phe and the tripeptide Ser-Pro-Phe. We have studied the rate of kinin degradation by each of these enzymes in patients with rheumatoid arthritis (RA) and with systemic lupus erythematosus (SLE), compared with the degradation rate in degenerative joint disease and normal subjects. Carboxypeptidase activity was the same in all individuals, but ACE activity was increased in the RA and SLE patients. We examined the effects of aspirin, sodium salicylate, auranofin, penicillamine, and corticosteroids on kinin metabolism, and all of these were marked inhibitors of ACE; however, only penicillamine had any demonstrable inhibition of carboxypeptidase. These observations suggest rapid degradation of DBK in patients with untreated RA and SLE, whereas drugs utilized in therapy have the opposite effects. Studies to examine the role of DBK in disease manifestations are in progress.
Effect of Serologic Status and Cesarean Delivery on Transmission Rates of Herpes Simplex Virus From Mother to Infant (2003)

Neonatal HSV infection rates can be reduced by preventing maternal acquisition of genital HSV-1 and HSV-2 infection near term. It can also be reduced by cesarean delivery and limiting the use of invasive monitors among women shedding HSV at the time of labor.
