Controlled stochastic model of a communication system with multiple sources (1991)

A stochastic model of buffering in a data communication system is considered, with source and sink transmission parameters depending on the number of active sources. For models in this control setting the authors analyze an effective numerical method for evaluating the equilibrium distribution of buffer content. The theoretical basis of the method is established first. Then, it is shown that the method has the same complexity, in terms of the total number of sources, as known analytical methods for the model with constant parameters. Asymptotics for tail probabilities at high buffer levels and under heavy load are also derived, and the complexity of their computation is compared with that of evaluating explicit formulas. In comparison to earlier results this approach reduces the complexity of computing the probability of overflow and its asymptotic estimates. The speed-up stems from the application of interpolation schemes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Volumetric Media Streaming for Augmented Reality (2018)

Volumetric media, popularly known as holograms, need to be delivered to users using both on-demand and live streaming, for new augmented reality (AR) and virtual reality (VR) experiences. As in video streaming, hologram streaming must support network adaptivity and fast startup, but must also moderate large bandwidths, multiple simultaneously streaming objects, and frequent user interaction, which requires low delay. In this paper, we introduce the first system designed specifically for streaming volumetric media. The system reduces bandwidth by introducing 3D tiles, and culling them or reducing their level of detail depending on their relation to the user's view frustum and distance to the user. To allocate bits among different tiles across multiple objects, we introduce a simple greedy yet provably optimal algorithm for rate-utility optimization, whose utility measures is based not only on the underlying quality of the representation, but on the level of detail relative to the user's viewpoint and device resolution. Simulation results show that the proposed algorithm provides superior quality compared to existing video-streaming approaches adapted to hologram streaming, in terms of utility and user experience over variable, throughput-constrained networks.

The Effect of a Spanish Virtual Pain Coach for Older Adults: A Pilot Study (2012)

Preliminary data indicate that the Spanish virtual pain coach might assist Spanish-speaking older adults to talk with their practitioner about their osteoarthritis pain and obtain opioid treatment changes, but that pain and depressive symptoms continue unchanged 1 month later. Additional refinement and testing is required for the Spanish-speaking virtual pain coach to determine acceptability and outcomes for assisting Spanish-speaking older adults to communicate about their pain with their primary care practitioner.
Fusion of Enhanced and Synthetic Vision System Images for Runway and Horizon Detection (2018)

UAV network operation enables gathering and fusion from disparate information sources for flight control in both manned and unmanned platforms. In this investigation, a novel procedure for detecting runways and horizons as well as enhancing surrounding terrain is introduced based on fusion of enhanced vision system (EVS) and synthetic vision system (SVS) images. EVS and SVS image fusion has yet to be implemented real-world situations due to signal misalignment. We address this through a registration step to align the EVS and SVS images. Four fusion rules combining discrete wavelet transform (DWT) sub-bands are formulated, implemented and evaluated. The resulting procedure is tested on real EVS-SVS image pairs and pairs containing simulated turbulence. Evaluations reveal that runways and horizons can be detected accurately even in poor visibility. Furthermore, it is demonstrated that different aspects of the EVS and SVS images can be emphasized by using different DWT fusion rules. The procedure is autonomous throughout landing, irrespective of weather. We believe the fusion architecture developed holds promise for incorporation into head-up displays (HUDs) and UAV remote displays to assist pilots landing aircraft in poor lighting and varying weather. The algorithm also provided a basis rule selection in other signal fusion applications.

X-ray Structure Analysis of a Dicopper Complex of a New Binucleating Ligand Containing a para-Xylyl Connecting Group; Large Cu…Cu Separation in [(CuCl2C18H20N3)2]·2H2O (1981)

Abstract Bimetallic coordination complexes containing two copper ions in close proximity are currently under extensive study. These structural units are known to be important in biological reactions involving molecular oxygen1 including oxygen transport,2 oxygen activation in the copper monooxygenase tyrosinase3 and the reduction of O2 in the copper oxidases.4 Examination of model systems is necessary to help elucidate the nature and mechanism of action of the copper containing active sites. In addition, model systems are of interest in studies of metal-metal interactions,5 mixed valence compounds6 and redox catalysts.6 and redox catalysts.7
Effect of caustic refining, solvent refining and steam refining on the deacidification and color of rice bran oil (1985)

Abstract Degummed rice bran oil was deacidified by caustic, solvent and steam refining processes. The steam refining process was optimized through a series of experiments with varying refining times (1–5 hr), temperatures (220–280 C) and amounts of steam (4–20%), at a pressure of 4 mmHg. The most significant factors affecting the degree of deacidification were the refining temperature and amount of steam. The correlation coefficient between quadratic equation obtained and experimental results was 0.96. Acid value and color of steam refined oil were not as good as those of caustic refined oil, but steam refining showed better retention of natural antioxidants than caustic or solvent refining. Steam refining is preferred for deacidification of rice bran oil because of reduced neutral oil loss and elimination of soap production. The important criteria in selecting a deacidification process are known to be the degree of deacidification, neutral oil loss, effect on bleaching and production of soapstock (2,8–10). In comparing caustic refining, solvent refining and steam refining, caustic refining of degummed rice bran oil resulted in satisfactory acid values and color but showed the worst result in neutral oil loss and produced large amounts of soapstock. Solvent refining was not shown to be efficient because of poor deacidification, high losses of neutral oil and darkening of color. Steam refining also was less effective than caustic refining in deacidification and bleaching. However, the degree of deacidification could be improved by development of a process to remove all the free fatty acids (8), and the color problem could be eliminated by including a preliminary bleaching step before steam distillation (10). The application of steam refining to rice bran oil will result in many advantages such as reduced neutral oil loss, no production of soap, and the production of high purity, industrial fatty acids.

Evaluation of Sulfonamides in the Protection of Phenylisoserine for the Semisynthesis of Taxol&#174; (2004)

The 4-nitrophenylsulfonyl, the benzothiazolsulfonyl and the anthracenesulfonyl protecting groups were evaluated in the protection of the phenylisoserine side chain, as part of a semisynthesis of paclitaxel. The mechanism for the cleavage of the anthracenesulfonyl group using thiols was also examined, and found to proceed by an addition elimination pathway, which is in contrast to the reported reductive mechanism. The use of the siamyldimethylsilyl group for protection of baccatin III is discussed and compared with the triethylsilyl group.
EVOLUTION AND SUBSTRATE SPECIFICITY OF CORONAVIRAL AND TOROVIRAL RECEPTOR-DESTROYING ENZYMES*□ S (2005)

Many viruses achieve reversible attachment to sialic acid (Sia) by encoding envelope glycoproteins with receptor-binding and receptor-destroying activities. Toroviruses and group 2 coronaviruses bind to O-acetylated Sias, presumably via their spike proteins (S), whereas other glycoproteins, the hemagglutinin-esterases (HE), destroy Sia receptors by de-O-acetylation. Here, we present a comprehensive study of these enzymes. Sialate-9-O-acetylesterases specific for 5-N-acetyl-9-Oacetylneuraminic acid, described for bovine and human coronaviruses, also occur in equine coronaviruses and in porcine toroviruses. Bovine toroviruses, however, express novel sialate-9-O-acetylesterases, which prefer the di-O-acetylated substrate 5-N-acetyl-7(8),9-di-O-acetylneuraminic acid. Whereas most rodent coronaviruses express sialate-4-O-acetylesterases, the HE of murine coronavirus DVIM cleaves 9-O-acetylated Sias. Under the premise that HE specificity reflects receptor usage, we propose that two types of Sias serve as initial attachment factors for coronaviruses in mice. There are striking parallels between orthomyxo- and nidovirus biology. Reminiscent of antigenic shifts in orthomyxoviruses, rodent coronaviruses exchanged S and HE sequences through recombination to extents not appreciated before. As for orthomyxovirus reassortants, the fitness of nidovirus recombinant offspring probably depends both on antigenic properties and on compatibility of receptor-binding and receptor-destroying activities.
Utilization of soybean meal as an alternative protein source in the Mediterranean yellowtail, Seriola dumerili (2005)

The availability of defatted soybean meal as a substitute for&#13;\nfish meal was evaluated in juvenile (450 g on average) yellowtail fed diets containing several levels of soybean meal&#13;\n(from 20 to 50%). After 153 days, liveweight averages were&#13;\n980, 925, 795 and 670 g for fish fed diets in which fish meal&#13;\nwas partially substituted with 20, 30, 40 and 50% soybean&#13;\nmeal, and feed conversion ratios were 2.79, 3.09, 4.57 and&#13;\n6.52, respectively. Regression analysis showed a negative&#13;\neffect of inclusion of soybean, although fish fed diets containing 20% and 30% of soybean did not present statistical&#13;\ndifferences and grew significantly more, and had a better feed&#13;\nconversion ratio, than fish fed 40 or 50% diets. Likewise,&#13;\nmuscle protein level was lower and lipid content was higher&#13;\nin fish fed 20 or 30% soybean. No differences were obtained&#13;\nfor protein digestibility coefficients of experimental diets.
Support Vector Regression Technique for Multimedia Quality Control in Multicast Networks (2013)

Multimedia quality control has become an important research field especially with the increased QoS requirements. In this paper, we propose a novel measurement and machine learning mixed approach for real-time multimedia quality control for multicast networks. Most of current adaptive multimedia quality control schemes are based on measurements of available network resources (whether active or passive measurements) or the use of network traffic models and they are reactive in nature. The proposed scheme is based on statistical learning techniques, such as Support Vector Regression (SVR), mixed with network measurements to predict packet loss rate in the near future and thus is a pro-active scheme. The prediction scheme triggers the rate control mechanism to pre-adjust the multimedia sending rate before network conditions start deteriorating. We use packet dispersion technique to measure end-to-end queuing delay combined with video display buffer information to train the acquired dataset for prediction in real time. The performance of the proposed scheme is evaluated over a set of network simulations. The results show that it is effective and exhibits superior performance compared to traditional measurement-based schemes.
Group Ratio Round-Robin: An O(1) Proportional Share Scheduler (2003)

Proportional share resource management provides a flexible and useful abstraction for multiplexing time-shared resources. However, previous proportional share mechanisms have either weak proportional sharing accuracy or high scheduling overhead. We present Group Ratio Round-Robin (GR3), a proportional share scheduler that can provide high proportional sharing accuracy with O(1) scheduling overhead. Unlike many other schedulers, a low-overhead GR3 implementation is easy to build using simple data structures. We have implemented GR3 in Linux and measured its performance against other schedulers commonly used in research and practice, including the standard Linux scheduler, Weighted Fair Queueing, Virtual-Time Round-Robin, and Smoothed Round-Robin. Our experimental results demonstrate that GR3 can provide much lower scheduling overhead and better scheduling accuracy in practice than these other approaches for large numbers of clients.
Role for aldehyde dehydrogenase in survival of progenitors for murine blast cell colonies after treatment with 4-hydroperoxycyclophosphamide in vitro. (1988)

We have studied the effects of 4-hydroperoxycyclophosphamide (4-HC) on murine hemopoietic progenitors. We found dose-dependent killing and differential sensitivities of colony forming cells with burst forming units-erythrocyte being most sensitive and colony-forming units-granulocyte/erythrocyte/macrophage/megakaryocyte most resistant. We also tested the effects of 4-HC on more primitive murine progenitors which were identifiable in our assay system when the addition of interleukin-3 was delayed until Day 7. We found that the sensitivities of the progenitors for blast cell colonies are similar to those of colony-forming units-granulocyte/erythrocyte/macrophage/megakaryocyte and that late-appearing blast cell colonies were particularly resistant to 4-HC. In order to study the mechanism of differential sensitivities of murine progenitors to 4-HC, we examined the sensitivities of murine progenitors to 4-HC after brief incubation with diethylaminobenzaldehyde, an inhibitor of aldehyde dehydrogenase. Progenitors for granulocyte/macrophage colonies, granulocyte/erythrocyte/macrophage/megakaryocyte colonies, and blast cell colonies became more sensitive to 4-HC and the differential sensitivities of the progenitors disappeared following this treatment. We also tested the sensitivities of the progenitors to phenylketophosphamide, an analogue of 4-HC which is resistant to inactivation by aldehyde dehydrogenase. Various colony-forming units exhibited a similar dose response to this compound. These data indicate that intracellular levels of aldehyde dehydrogenase might play an important role in differential sensitivities of murine colony-forming units to 4-HC.
Photoelectrochemical Reduction of Carbon Dioxide at Si(111) Electrode Modified by Viologen Molecular Layer with Metal Complex (2012)

Abstract Photoelectrochemical carbon dioxide reduction was carried out at a p-type Si(111) electrode modified with a viologen molecular layer and [AuCl4]− or [PdCl4]2−. It was proven that the reduction reaction was mediated by viologen moiety and while CO2 reduction was dominant at the Si(111) electrode modified with [PdCl4]2− in the potential region where viologen moiety was in the first reduced state, it became dominant at the electrode modified with [AuCl4]− when viologen moiety became the second reduced state. FT-IR measurement confirmed the formation of formic acid/formate ion at the [PdCl4]2−/viologen-modified Si electrode.
The role of MHC- and non-MHC-associated genes in determining the human immune response to malaria antigens (1996)

Individual susceptibility to malaria infection, disease and death is influenced by host genotype, parasite virulence and a number of environmental factors including malaria-specific immunity. Immune responses are themselves determined by a combination of host genes and environmental effects. The extent to which host genotype limits the spectrum of possible immune responses may influence the outcome of infection and has consequences for vaccine design. Associations have been observed between human major histocompatibility complex (MHC) genotype and susceptibility to severe malaria, but no similar associations have been observed for mild malarial disease or for specific antibody responses to defined malaria antigens. Epidemiological studies have shown that, in practice, neither T helper cell nor antibody responses to malaria parasite are limited by host MHC genotype, but have revealed that genes lying outside the MHC may influence T cell proliferative responses. These genes have yet to be identified, but possible candidates include T cell receptor (TcR) genes, and genes involved in TcR gene rearrangements. More importantly, perhaps, longitudinal epidemiological studies have shown that the anti-malarial antibody repertoire is selective and becomes fixed in malaria-immune individuals, but is independent of host genotype. These findings suggest that the antibody repertoire may be determined, at least in part, by stochastic events. The first of these is the generation of the T and B cell repertoire, which results from random gene recombinations and somatic mutation and is thus partially independent of germline genes. Secondly, of the profusion of immunogenic peptides which are processed and presented by antigen presenting cells, a few will, by chance, interact with T and B cell surface antigen receptors of particularly high affinity. These T and B cell clones will be selected, will expand and may come to dominate the immune response, preventing the recognition of variant epitopes presented by subsequent infections-a process known as original antigenic sin or clonal imprinting. The immune response of an individual thus reflects the balance between genetic and stochastic effects. This may have important consequences for subunit vaccine development.
An inductor-less LTE receiver using an 8-path filter for TX leakage suppression (2014)

In this paper, an inductor-less mobile radio receiver is proposed. An 8-path band pass filter is employed at the input of the receiver to provide TX leakage suppression. The receiver is designed for LTE and UMTS lower bands and tested for worst case duplex distance of 32 MHz. The filter can be programmed to trade the noise degradation for TX suppression. For 0.3 dB noise degradation, IIP2 and IIP3 improvements can reach 17 and 11 dB respectively. The receiver has been fabricated in a 28 nm CMOS technology.
Evidence-Based Practice and Activity-Based Therapy for Recovery of Posture, Standing, and Walking (2011)

Abstract This chapter reviews physical rehabilitation for posture, standing, and walking from an historical perspective, and provides a context for the emergence of locomotor training as an activity-based therapy after spinal cord injury (SCI) and stroke by implementing evidence-based practice. The chapter is not intended to be a comprehensive review of the functional consequences after injury or insult or a review of all the available rehabilitation strategies for SCI or stroke. Rather, it is intended to be a discussion within the framework of introducing locomotor training as a new strategy to augment already successful therapeutic approaches. The review presented is not a discourse of accepted clinical practices but is a summary of evidence from studies in individuals after SCI or stroke related to functional deficits affecting mobility, posture, standing, and walking.

ESTIMATING FOOD TEMPERATURES DURING VARIOUS PROCESSING OR HANDLING TREATMENTS (1971)

SUMMARY— A procedure was developed for predicting the transient temperature of a solid food exposed to time variable ambient temperatures. Duhamel's theorem was applied to the empirical formulas used for calculating the temperature of a food subjected to a step change in its ambient temperature. The formulas contain two constants: f, the slope index of a heating or cooling curve of a food; and j, the intercept coefficient of the heating or cooling curve. With the procedure developed transient temperature can be estimated without regard to the geometric shape of the food provided the f and j values are known. A table is presented to reduce computations involved in the procedure. Sample calculations are given for a fresh orange, a fresh carrot and a canned food product.
