Changes in Lactacidemia and Glycemia of Automobilism Race Car Drivers after Old Stock Race Category Racing (2021)

Introduction: Few studies are available on the acute effects of motor racing on race drivers lactacidemia and blood glucose. Objective: To verify changes in lactacidemia and glycemia of race car drivers in the Old Stock Race category. Method: The concentrations of plasma lactate and glycemia of eight male race car drivers in the Old Stock Race category (OSR) were recorded thirty minutes before the start and ten minutes after the start of the race. The data were obtained during the 4th round of the 2018 Season of the OSR held at the Jos Carlos Pace race track (Interlagos / So Paulo-Brazil). For comparison between moments, paired Students t-test paired on variables with normal distribution was used, with Bonferronis post-test, adopting a 5% significance level, for all analyses. Descriptively the data were compared using the Percentage Delta and presented in graphical and tabular form.Results: It was found that the lactate concentration increased significantly after the race (2.26 + 0.76 vs. 3.56 + 0.97 mmol / L, p = 0.0101). On the other hand, there was no change in blood glucose (122 +15.3 vs. 123 + 19.8 mg / dl, p = 0.8828).Conclusion: The significant increase in lactacidemia after the race indicates that there was an anaerobic muscle requirement during the race. On the other hand, there was no change in the mean blood glucose after the race.Key Words:Motor Racing, Human Performance, Exercise, Experimental Research
Polypeptide mapping of citrus tristeza virus strains (1987)

Two coat proteins were present when purified citrus tristeza virus (CTV) virions were dissociated and examined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The larger coat protein (CP1), about 23000 MW, was present in greater quantity than the smaller coat protein (CPZ), about 21 000 MW. Coat proteins from several aphid-transmitted Florida CTV isolates having different biolo~ical activities were compared by polypeptide mapping on SDS-PAGE after dissociation and proteolytic digestIon. The polypeptide maps revealed similar patterns for all isolates with only minor differences between some isolates. Polypeptide mapping of CTV coat proteins would not be a useful general technique to detect strain differences.

Optimization of the grating efficiency in grazing incidence (1987)

A detailed numerical study of the sinusoidal and triangular groove shape grating efficiency behavior has been carried out in grazing incidence using rigorous electromagnetic theory. The optimized parameters for maximum efficiency have been found for both types of grating. The influence of the metal reflectance and the oxide layer are discussed, and some results of higher order efficiency are also presented.
Real-Time Hallucination Simulation and Sonification through User-Led Development of an iPad Augmented Reality Performance (2014)

The simulation of visual hallucinations has multiple applications. The authors present a new approach to hallucination simulation, initially developed for a performance, that proved to have uses for individuals suffering from certain types of hallucinations. The system, originally developed with a focus on the visual symptoms of palinopsia experienced by the lead author, allows real-time visual expression using augmented reality via an iPad. It also allows the hallucinations to be converted into sound through visuals sonification. Although no formal experimentation was conducted, the authors report on a number of unsolicited informal responses to the simulator from palinopsia sufferers and the Palinopsia Foundation.
A New Agent-Based Intelligent Network Architecture (2022)

The advent of 5G and the design of its architecture has become possible because of the previous individual scientific works and standardization efforts on cloud computing and network softwarization. Software-defined networking and network function virtualization started separately to find their convolution into 5G network architecture. Also, the ongoing design of the future beyond 5G (B5G) and 6G network architecture cannot overlook the pivotal inputs of different independent standardization efforts on autonomic networking, service-based communication systems, and multi-access edge computing. This article provides the design and characteristics of an agent-based, softwarized, and intelligent architecture, which coherently condenses and merges the independent proposed architectural works by different standardization working groups and bodies. This novel work is a helpful means for the design and standardization process of the future 5G and 6G network architecture.
Highly Oriented Monolayer Graphene Grown on a Cu/Ni(111) Alloy Foil (2018)

Fast-growth of single crystal monolayer graphene by CVD using methane and hydrogen has been achieved on "homemade" single crystal Cu/Ni(111) alloy foils over large area. Full coverage was achieved in 5 min or less for a particular range of composition (1.3 at.% to 8.6 at.% Ni), as compared to 60 min for a pure Cu(111) foil under identical growth conditions. These are the bulk atomic percentages of Ni, as a superstructure at the surface of these foils with stoichiometry Cu<sub>6</sub>Ni<sub>1</sub> (for 1.3 to 7.8 bulk at.% Ni in the Cu/Ni(111) foil) was discovered by low energy electron diffraction (LEED). Complete large area monolayer graphene films are either single crystal or close to single crystal, and include folded regions that are essentially parallel and that were likely wrinkles that "fell over" to bind to the surface; these folds are separated by large, wrinkle-free regions. The folds occur due to the buildup of interfacial compressive stress (and its release) during cooling of the foils from 1075 °C to room temperature. The fold heights measured by atomic force microscopy (AFM) and scanning tunneling microscopy (STM) prove them to all be 3 layers thick, and scanning electron microscopy (SEM) imaging shows them to be around 10 to 300 nm wide and separated by roughly 20 μm. These folds are always essentially perpendicular to the steps in this Cu/Ni(111) substrate. Joining of well-aligned graphene islands (in growths that were terminated prior to full film coverage) was investigated with high magnification SEM and aberration-corrected high-resolution transmission electron microscopy (TEM) as well as AFM, STM, and optical microscopy. These methods show that many of the "join regions" have folds, and these arise from interfacial adhesion mechanics (they are due to the buildup of compressive stress during cool-down, but these folds are different than for the continuous graphene films-they occur due to "weak links" in terms of the interface mechanics). Such Cu/Ni(111) alloy foils are promising substrates for the large-scale synthesis of single-crystal graphene film.
Ham-Wasserman Lecture: Role of the Plasminogen System in Fibrin-Homeostasis and Tissue Remodeling (2001)

Plasminogen can be converted to plasmin either via the tissue-type plasminogen activator (t-PA) or via the urokinase-type plasminogen activator (u-PA)/u-PA receptor (u-PAR) pathway. A dual role for these pathways is now well established: 1) t-PA is involved in fibrin homeostasis and 2) u-PA is primarily involved in cell migration and tissue remodeling. t-PA mediated activation is used for thrombolytic therapy of acute myocardial infarction and some other thromboembolic diseases. The u-PA mediated pathway, in concert with the matrix metalloproteinase (MMP) system, plays a pleiotropic role in arterial neointima formation, atherosclerosis, angiogenesis, tumor growth metastasis, and infarction. However, therapeutic interventions in the u-PA/MMP system remain to be further defined.
The effects of specific medical conditions on the functional limitations of elders in the Framingham Study. (1994)

In general, stroke, depressive symptomatology, hip fracture, knee osteoarthritis, and heart disease account for more physical disability in noninstitutionalized elderly men and women than other diseases.
Kidneys From Elderly Deceased Donors—Is 70 the New 60? (2019)

There is a growing shortage of kidney donors leading to extended transplant waiting times associated with increased mortality. To expand the donor pool, clinicians nowadays regularly accept organs from elderly donors, including those aged ≥70 years. There is only limited and conflicting data whether kidneys from these elderly donors allow for satisfactory allograft outcome rates. To asses this question, the 5-year death censored graft survival of 116,870 adult first deceased donor kidney allograft recipients that were transplanted at European centers between 1997 and 2016 and reported to the "Collaborative Transplant Study" were analyzed using Kaplan-Meier analysis and country stratified Cox regression. The combinations of the two transplant periods 1997-2006 and 2007-2016 with the donor age categories 18-49, 50-59, 60-69, and ≥70 years were considered. From 1997-2006 to 2007-2016, the median donor age increased from 50 to 55 years and the proportion of kidneys from ≥60-year-old donors rose from 24.1 to 38.8%. At the same time, the proportion of kidneys from ≥70-year-old donors more than doubled (6.7 vs. 15.4%). Between 1997-2006 and 2007-2016, the 5-year graft survival improved in all donor age categories. During 2007-2016, the 5-year death censored graft survival of kidneys from ≥70-year-old donors was comparable to that of kidneys from 60 to 69-year-old donors during 1997-2006. This was true both for younger recipients (18-64 years) and older recipients (≥65 years). Among the younger recipients, 45-64-year-old recipients showed the best death censored graft survival rates for kidneys from old donors. In the country-stratified Cox regression analysis, compared to the reference of grafts from 18 to 49-year-old donors, the hazard ratio for grafts from ≥70-year-old donors during 2007-2016 was 1.92, exactly the same as the hazard ratio for grafts from 60 to 69-year-old donors during 1997-2006. Our analysis indicates that within only one further decade (1997-2006 vs. 2007-2016) the 5-year death censored graft survival of kidneys from ≥70-year old donors improved to the level of kidneys from 60 to 69-year-old donors in the previous decade.
Grid-guided Neural Radiance Fields for Large Urban Scenes (2023)

Purely MLP-based neural radiance fields (NeRF-based methods) often suffer from underfitting with blurred renderings on large-scale scenes due to limited model capacity. Recent approaches propose to geographically divide the scene and adopt multiple sub-NeRFs to model each region individually, leading to linear scale-up in training costs and the number of sub-NeRFs as the scene expands. An alternative solution is to use a feature grid representation, which is computationally efficient and can naturally scale to a large scene with increased grid resolutions. However, the feature grid tends to be less constrained and often reaches suboptimal solutions, producing noisy artifacts in renderings, especially in regions with complex geometry and texture. In this work, we present a new framework that realizes high-fidelity rendering on large urban scenes while being computationally efficient. We propose to use a compact multiresolution ground feature plane representation to coarsely capture the scene, and complement it with positional encoding inputs through another NeRF branch for rendering in a joint learning fashion. We show that such an integration can utilize the advantages of two alternative solutions: a light-weighted NeRF is sufficient, under the guidance of the feature grid representation, to render photorealistic novel views with fine details; and the jointly optimized ground feature planes, can meanwhile gain further refinements, forming a more accurate and compact feature space and output much more natural rendering results.
Knowledge Discovery and Causality in Urban City Traffic (2013)

The increase in number of vehicles has created problems in many cities across the globe. Building comprehensive knowledge base about global city dynamics and traffic distribution is a key step to provide fundamental solution to the problems. In this paper, we examine a readily available data source; the existing infrastructure of traffic cameras around the world. We have collected real time traffic data from 2,700 public online traffic camera distributed across 10 cities in four continents for a duration of six months. Our platform allows us to automatically search public cameras, collect and process imagery data, remove outliers, and extract traffic density from those images in a highly scalable way. A time series model employing a co-integrated vector autoregression model is presented in which traffic forecasts may be produced and regions of the city not well observed may be suggested. In addition, a topological comparison of six of these networks is presented.
Introduction of molecular spacers between the crosslinks of a cellulose‐based superabsorbent hydrogel: Effects on the equilibrium sorption properties (2003)

Abstract The possibility to modulate cellulose‐based hydrogel sorption properties through the insertion of molecular spacers between the crosslinks was investigated. Starting polymers were the sodium salt of carboxymethyl cellulose, a polyelectrolyte cellulose derivative, and hydroxyethyl cellulose, a nonpolyelectrolyte derivative. Poly(ethylene glycol) with various molecular weights was linked by its free ends at two divinyl sulfone (DVS) crosslinker molecules, to increase the average distance between two crosslinking sites and thus to act as a spacer. Both the effect of the concentration and the molecular weight of the spacer on the hydrogel final sorption properties in water and water solutions were investigated. The presence of the spacer allowed us also to perform hydrogel synthesis with higher concentrations of cellulose in the reactive mixture, and the effect of the polymer concentration in the batch was analyzed. Hydrogels obtained in the presence of spacers displayed significantly higher equilibrium sorption properties than those of the ones obtained without spacers. © 2003 Wiley Periodicals, Inc.

Numerical Investigation of Shrouded Ejector-Enhanced Pulse Combustor Performance at High Pressure (2016)

A computational fluid dynamics investigation of a pressure-gain combustor system for gas turbine applications is described. The system consists of a valved pulse combustor and an ejector, housed within a shroud. The computational fluid dynamics solver is first validated by comparing its output to experimental measurements done on a pulse combustor operating at sea-level static conditions. Subsequently, the combustor inlet pressure and temperature are increased in the simulations to more closely align with those seen downstream of a compressor. Several parameters that influence combustor performance are then varied in order to demonstrate the potential benefit of optimization efforts. Emissions calculations are also performed. It is found that efficient high-pressure operation is possible and that system pressure gain of nearly 3% (at gas turbine compatible combustor temperature ratios) is achievable, with nearly smooth exit flow, having a competitive emission index. The potential for pulse combustors to achieve ultra-low levels of emissions at high-pressure conditions is also demonstrated.

A Multi-Scale Spatiotemporal Perspective of Connected and Automated Vehicles: Applications and Wireless Networking (2016)

Wireless communication is a basis of the vision of connected and automated vehicles (CAVs). Given the heterogeneity of both wireless communication technologies and CAV applications, one question that is critical to technology road-mapping and policy making is which communication technology is more suitable for a specific CAV application. Focusing on the technical aspect of this question, we present a multi-scale spatiotemporal perspective of wireless communication technologies as well as canonical CAV applications in active safety, fuel economy and emission control, vehicle automation, and vehicular infotainment. Our analysis shows that CAV applications in the regime of small spatiotemporal scale communication requirements are best supported by V2V communications, applications in the regime of large spatiotemporal scale communication requirements are better supported by cellular communications, and applications in the regime of small spatial scale but medium-to-large temporal scale can be supported by both V2V and cellular communications and provide the opportunity of leveraging heterogeneous communication resources.
Video frame rate control for non-guaranteed network services with explicit rate feedback (2002)

An adaptive video frame rate control method is proposed for the network of time-varying rate channel with explicit rate feedback. It consists of a prediction module of future channel rate and an adaptive frame discarding and skipping module. We derive an encoder buffer constraint which guarantees an end-to-end delay bound of video frames. The recursive least-squares (RLS) method is used as a tool to predict the low frequency component of channel rate. The adaptive frame discarding method prevents delay violation of frames due to the channel rate prediction error. Also, the frame skipping method adapts the encoder output rate to the channel rate while keeping a constant level of video quality. From the simulation result, it is shown that the proposed method keeps the decoded image quality nearly constant with much less number of skipped frames and no delay violating frame during the congestion period.
Flow Cytometric Isolation of Differentiated Cell-types from Embryoid Bodies (1993)

Induced differentiation of pluripotent embryonal carcinoma stem cells has been characterized as a cell culture model of early mammalian development. Since these cells can be prepared in bulk, they offer the opportunity to isolate relatively large amounts of biological material analogous to cell-types in the developing embryo; cell types that are both few in number and difficult to identify. We have established and morphologically and molecularly characterized differentiated embryoid bodies derived from the embryonal carcinoma cell line F9. Using the technique of fluorescent-activated cell sorting we were able to distinguish and isolate two differentiated cell-types from this model system based upon differences in their autofluorescence. We were then able to molecularly characterize expression of the endodermal marker alpha-fetoprotein in these isolated cell populations.
Electron Transfer Processes in Subunit I Mutants of CytochromeboQuinol Oxidase inEscherichia coli (2009)

Cytochrome bo is a terminal quinol oxidase in the aerobic respiratory chain of Escherichia coli. Subunit I binds all four redox centers, and electrons are transferred from quinols to high-spin heme o and Cu(B) through a bound uniquinone-8 and low-spin heme b. To explore the role of conserved charged amino acid residues, we examined the one-electron transfer processes in subunit I mutants. We found that all the mutants examined increased the electron transfer rate from the bound quinone to heme b more than 40-fold. Tyr288 and Lys362 are key residues in the K-channel for charge compensation of the heme o-Cu(B) binuclear center with protons. The Tyr288Phe and Lys362Gln mutants showed 100-fold decreases in heme b-to-heme o electron transfer, accompanied by large increases in the redox potential of heme o. Our results indicate that electromagnetic coupling of hemes is important for facilitated heme-heme electron transfer in cytochrome bo.
