Dynamic functional modules in co-expressed protein interaction networks of dilated cardiomyopathy (2010)

We propose a novel framework to analyze the interaction networks in different biological states. It successfully reveals network modules closely related to heart failure; more importantly, these network dynamics provide new insights into the cause of dilated cardiomyopathy. The revealed molecular modules might be used as potential drug targets and provide new directions for heart failure therapy.
The Recurrence of Helicobacter pylori Infection: Incidence and Variables Influencing It. A Critical Review (2005)

The rate of H. pylori recurrence after eradication of the microorganism seems to be relatively low, at least in developed countries, where the mean annual reinfection rate is of approximately 3% per patient-year of follow-up, although the risk of reinfection in some developing regions is considerably higher. Several findings suggest that recrudescence rather than reinfection is likely to be responsible for most cases of recurrence: (i) the recurrences decrease with time and decline sharply after the first year, and (ii) studies using molecular fingerprinting techniques (polymerase chain reaction [PCR]) confirm that the identified microorganisms (before and after therapy) are usually genetically identical. The lower the efficacy of an antibiotic therapy, the greater the likelihood that recurrence occur, again suggesting that in these cases temporary "clearance" has been achieved rather than true eradication. The value of the (13)C-urea breath test after treatment is higher in those patients who suffer a recurrence; therefore, selection of a lower cut-off value may be helpful to maintain the diagnostic accuracy of posttreatment breath test, and thus preventing recrudescences. The observation of a pattern of histological (active) gastritis without the concomitant finding of H. pylori must raise the suspicion of a diagnostic error. Some studies suggest that recurrence is relatively infrequent, even if the patient's spouse is H. pylori-positive, suggesting that the patient's partner does not act as a reservoir for the reinfection. However, other investigators achieve contrary results, although a common exogenous source of H. pylori (for both partner's infection and patient's reinfection) cannot be ruled out. The oral cavity may be a potential source for recrudescence of gastric infection after successful therapy. When peptic ulcer reappears (sometimes with bleeding recurrence) or gastric MALT (mucosa-associated lymphoid tissue) lymphoma relapses after previous H. pylori eradication, recolonization of the gastric mucosa by the organism has almost always occurred.
Control for railways - active suspensions and other opportunities (2011)

The renewed importance of railways worldwide has stimulated a need for innovation applied to the system as a whole over a range of disciplines, and control engineering is one of the important disciplines for the industry. This paper summarises the possibilities of using advanced control in general, and discusses the opportunities and challenges for the railway vehicles in particular.
Angular Remanence and Anisotropy Orientation Distribution in Nickel Films on LiNbO3 (2021)

Nickel thin films (100 nm) deposited on <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$128^{\circ } Y$ </tex-math></inline-formula> -cut: LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> exhibits a well-defined, uniaxial, magnetic anisotropy after annealing at 325 °C. Simulating the magnetization of these films using a temperature-dependent Stoner–Wohlfarth (SW) model indicates that the films have a very narrow angular distribution of anisotropy axis orientations. Here, we report a direct measurement of the angular distribution of anisotropy orientation by measuring the angular remanence after magnetic saturation. When magnetized to saturation in any direction away from the hard axis, these samples remain nearly uniformly magnetized, with the easy axis remnant magnetization very close to the saturation magnetization (> <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$0.97M_{S}$ </tex-math></inline-formula> ). When the angle ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\alpha$ </tex-math></inline-formula> ) between the saturating field and the hard axis is <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\vert \alpha \vert &lt; 1$ </tex-math></inline-formula> °, the easy axis remanence drops dramatically, indicating that the sample is no longer uniformly magnetized and has broken up into domains. When magnetized on the hard axis, the easy axis remanence approaches zero. The angular range over which the easy axis remanence drops significantly is a measure of the angular distribution of the anisotropy axes. The full-width at half-maximum (FWHM) of the easy axis remanence as a function of angle <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$(\alpha)$ </tex-math></inline-formula> is approximately 0.44° for annealed nickel thin films on <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$128^{\circ } Y$ </tex-math></inline-formula> -cut: LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> . The angular remanence is modeled numerically, assuming an ensemble of SW particles with a distributed anisotropy orientation. The magnetic domain structure of the films is confirmed by magneto-optic Kerr effect imaging.
Research is needed to inform environmental management of hydrothermally inactive and extinct polymetallic sulfide (PMS) deposits (2020)

Polymetallic sulfide (PMS) deposits produced at hydrothermal vents in the deep sea are of potential interest to miners. Hydrothermally active sulfide ecosystems are valued for the extraordinary chemosynthetic communities that they support. Many countries, including Canada, Portugal, and the United States, protect vent ecosystems in their Exclusive Economic Zones. When hydrothermal activity ceases temporarily (dormancy) or permanently (extinction), the habitat and associated ecosystem change dramatically. Until recently, so-called “inactive sulfide” habitats, either dormant or extinct, received little attention from biologists. However, the need for environmental management of deep-sea mining places new imperatives for building scientific understanding of the structure and function of inactive PMS deposits. This paper calls for actions of the scientific community and the emergent seabed mining industry to i) undertake fundamental ecological descriptions and study of ecosystem functions and services associated with hydrothermally inactive PMS deposits, ii) evaluate potential environmental risks to ecosystems of inactive PMS deposits through research, and iii) identify environmental management needs that may enable mining of inactive PMS deposits. Mining of some extinct PMS deposits may have reduced environmental risk compared to other seabed mining activities, but this must be validated through scientific research on a case-by-case basis.
Performance and characterization of building integrated photovoltaic panels (2003)

Buildings consume more than two-thirds of the electricity in the United States. The incorporation of photovoltaics into buildings, referred to as building integrated photovoltaics (BIPV), offers an aesthetically pleasing means of displacing centrally located utility generated power with distributed renewable energy. Building integrated photovoltaics replace conventional building elements such as roof tiles, asphalt shingles, facade elements, and shading devices with photovoltaic modules that perform the same functions but also provide electrical power. A barrier to BIPV implementation is the lack of validated predictive tools to quantify the achievable energy savings. Building owners, architects, and designers need these predictive tools in order to make informed decisions about the economic viability of a proposed BIPV project. The Building and Fire Research Laboratory at the National Institute of Standards and Technology (NIST) is providing high quality experimental data for the development, validation, and improvement of computer simulation tools. Among the computer simulation tools available for predicting the performance of photovoltaic (PV) systems are IV Curve Tracer, developed by Sandia National Laboratories, and PHANTASM, authored by the University of Wisconsin. This paper describes NIST's BIPV "test bed" a facility that is used to measure the annual performance of different types of BIPV panels. Measurements are presented that compare the performance of four different cell technologies and document the effect of installing thermal insulation at the interior surface of BIPV panels. The annual performance of each BIPV panel is evaluated relative to its performance at standard rating conditions.
pH-responsive protein microcapsules fabricated via glutaraldehyde mediated covalent layer-by-layer assembly (2008)

Bovine serum albumin (BSA) hollow microcapsules were fabricated through glutaraldehyde (GA) mediated covalent layer-by-layer assembly. The GA cross-linking of the adsorbed BSA on the colloidal particles enabled their surfaces to be covered by reactive aldehyde groups, which reacted with BSA molecules to result in another covalently linked layer. Repeating of this cycle could then yield particles coated with BSA multilayers. Hollow microcapsules well dispersed in water were obtained after core removal. The good integrity and morphology of the BSA capsules were confirmed and characterized by confocal laser scanning microscopy, scanning electron microscopy and scanning force microscopy. The obtained BSA microcapsules possess reversible pH response, i.e., the capsules are permeable to macromolecules below pH 4 or above pH 10, while impermeable in between. The mechanisms of permeability transition were discussed. Using this property, dextran, with a molecular weight of ~155 kDa, was successfully loaded.
Power-Handling Capability of Superconducting Transmit Bandpass Filter When Number of Bulk Resonators Is Increased (2016)

We designed three-and five-pole HTS filters with superconducting bulk resonators. We used MW-Studio software to simulate the frequency responses and current densities of these HTS filters. We estimated that the power-handling capability of the five-pole bulk filter was about 1.7 times higher than that of the three-pole bulk filter from the simulation results. We fabricated these HTS filters and measured their frequency responses and power-handling capabilities at 20 K. The five-pole bulk filter showed sharper skirt characteristic that is approximately 2.1 times than that of the three-pole bulk filter, and the power-handling capabilities of the three-and five-pole bulk filters were 41.7 and 114 W, respectively. Therefore, we clarified that the five-pole bulk filter was more suitable for a steep skirt characteristic and a high power-handling capability than the three-pole bulk filter.
Edge Computing and Adaptive Fault-Tolerant Tracking Control Algorithm for Smart Buildings: A Case Study (2020)

The development and integration of technologies such as the Internet of Things (IoT) or edge computing devices is contributing to the formation of an increasingly digital, intelligent and connected world. As a result, there is a massive flow of data in different sectors of human activity. One example is intelligent buildings, where thousands of components, devices, systems and suppliers interact. In this context, failures in control and monitoring systems are frequent. To analyze this situation, this paper presents as a case study the problem of fault-tolerant robust adaptive monitoring control with state prediction performance for a class of IoT temperature systems subject to uncertainties of precision states and external disturbances. The authors propose a new control strategy based on consensus game theory and prediction of future precision states to reduce tracking error and improve algorithm efficiency. The authors present the development of a new algorithm that improves the functioning of monitoring and control of parcel networks. This has the purpose of increasing the energy efficiency of the same and ensure the effectiveness of our adaptive temperature control algorithm, compared to existing results. With the simulation presented in this research, it is possible to conclude that a new fault tolerant error tracking algorithm ensures robust monitoring of the reference model. It was shown that the predicted temperature signal is limited by a small range close to the collected temperature data. A case study result is provided to demonstrate the effectiveness of the proposed fault-tolerant adaptive monitoring control algorithm.
Modulating Isoprenoid Biosynthesis Increases Lipooligosaccharides and Restores Acinetobacter baumannii Resistance to Host and Antibiotic Stress (2020)

Acinetobacter baumannii is a leading cause of ventilator-associated pneumonia and a critical threat due to multidrug resistance. The A. baumannii outer membrane is an asymmetric lipid bilayer composed of inner leaflet glycerophospholipids and outer leaflet lipooligosaccharides. Deleting mlaF of the maintenance of lipid asymmetry (Mla) system causes A. baumannii to become more susceptible to pulmonary surfactants and antibiotics and decreases bacterial survival in the lungs of mice. Spontaneous suppressor mutants isolated from infected mice contain an ISAba11 insertion upstream of the ispB initiation codon, an essential isoprenoid biosynthesis gene. The insertion restores antimicrobial resistance and virulence to ΔmlaF. The suppressor strain increases lipooligosaccharides, suggesting that the mechanism involves balancing the glycerophospholipids/lipooligosaccharides ratio on the bacterial surface. An identical insertion exists in an extensively drug-resistant A. baumannii isolate, demonstrating its clinical relevance. These data show that the stresses bacteria encounter during infection select for genomic rearrangements that increase resistance to antimicrobials.
Factors Affecting the Clearance and Biodistribution of Polymeric Nanoparticles (2008)

Nanoparticle (NP) drug delivery systems (5-250 nm) have the potential to improve current disease therapies because of their ability to overcome multiple biological barriers and releasing a therapeutic load in the optimal dosage range. Rapid clearance of circulating nanoparticles during systemic delivery is a critical issue for these systems and has made it necessary to understand the factors affecting particle biodistribution and blood circulation half-life. In this review, we discuss the factors which can influence nanoparticle blood residence time and organ specific accumulation. These factors include interactions with biological barriers and tunable nanoparticle parameters, such as composition, size, core properties, surface modifications (pegylation and surface charge), and finally, targeting ligand functionalization. All these factors have been shown to substantially affect the biodistribution and blood circulation half-life of circulating nanoparticles by reducing the level of nonspecific uptake, delaying opsonization, and increasing the extent of tissue specific accumulation.
Nematode-Applied Technology for Human Tumor Microenvironment Research and Development (2022)

Nematodes, such as <i>Caenorhabditis elegans</i>, have been instrumental to the study of cancer. Recently, their significance as powerful cancer biodiagnostic tools has emerged, but also for mechanism analysis and drug discovery. It is expected that nematode-applied technology will facilitate research and development on the human tumor microenvironment. In the history of cancer research, which has been spurred by numerous discoveries since the last century, nematodes have been important model organisms for the discovery of cancer microenvironment. First, microRNAs (miRNAs), which are noncoding small RNAs that exert various functions to control cell differentiation, were first discovered in <i>C. elegans</i> and have been actively incorporated into cancer research, especially in the study of cancer genome defects. Second, the excellent sense of smell of nematodes has been applied to the diagnosis of diseases, especially refractory tumors, such as human pancreatic cancer, by sensing complex volatile compounds derived from heterogeneous cancer microenvironment, which are difficult to analyze using ordinary analytical methods. Third, a nematode model system can help evaluate invadosomes, the phenomenon of cell invasion by direct observation, which has provided a new direction for cancer research by contributing to the elucidation of complex cell-cell communications. In this cutting-edge review, we highlight milestones in cancer research history and, from a unique viewpoint, focus on recent information on the contributions of nematodes in cancer research towards precision medicine in humans.

OLDER DRIVERS' PERCEPTIONS OF PROBLEMS IN FREEWAY USE (1990)

Using a focus group technique of meeting with older drivers to discuss their concerns about driving on freeways, was found that older drivers freeways just about as frequently as younger drivers. It was also found that as they grow older, drivers tend to be more selective as to when they the freeway in order to avoid peak congeston periods and night driving. Concerning what problems older drivers experience with regard to freeways, was determined that the following head the list: fear of big trucks, speeding drivers, short merge lanes, weaving merge lanes, and discourteous drivers. Another major concern of older drivers was found to be personal security--the fear of breaking down on a freeway, missing an exit and not being able to get back, and the lack of roadside security items such as paved shoulders on which to pull off the road and emergency call-boxes. Older drivers stressed that with freeway driving they face a use or lose it situation, meaning that they had to continue to freeways on a regular basis in order to retain their driving ability and confidence.
Energy efficient proportionally fair uplink offloading for IP Flow Mobility (2014)

The continuous increase of mobile data demand has led to mobile data offloading as a solution for the network congestion problem. The majority of the state-of-the-art is focused on the downlink offloading, while the change of mobile user habits, like mobile content creation and uploading, makes uplink offloading a rising issue. In this work we focus on the uplink offloading using Ip Flow Mobility (IFOM). IFOM allows a LTE mobile User Equipment (UE) to maintain two concurrent data streams, one through LTE and the other through WiFi access technology, that presents uplink limitations due to the inherent fairness design of IEEE 802.11 DCF. In this paper, we propose a weighted Proportionally Fair Bandwidth (PFB) allocation algorithm, for the WiFi access, in conjunction with a pricing-based rate allocation for the LTE uplink, aiming to improve the energy efficiency of the UEs that operate under the concurrent use of access technologies that IFOM provides. We present a theoretical analysis of the proposed schemes and evaluate their performance in terms of energy efficiency through simulations.
Relationship Between Heart Rate and Oxygen Kinetics During Constant Workload Exercise (1995)

The results of this study suggest that oxygen kinetics and exertional symptoms are improved by an abrupt increase in pacing rate at the onset of exercise to a value that is appropriate for metabolic demand as compared with the DDD pacing mode in patients with normal sinus node function. In contrast, an overly aggressive chronotropic response was not associated with improved oxygen kinetics or exertional symptoms.
Optimizing the Waterflooding Performance of a Carbonate Reservoir with Internal Control Valves (2013)

Abstract Intelligent digital oilfield (iDOF) operations include the transfer, monitoring, visualization, analysis, and interpretation of real-time data. Enabling this process requires a significant investment to upgrade surface, subsurface, and well instrumentation and also the installation of a sophisticated infrastructure for data transmission and visualization. Once upgraded, the system is then capable of transferring massive quantities of data, converting it into real information at the right time. The transformation of raw data into information is achieved through intelligent, automated work processes, which are referred to here as "smart flows." Smart flows assist engineers in their daily well surveillance activities, helping make them more productive and improve decision making. A major oil and gas operator in the Middle East has invested in such an infrastructure and is developing a set of smart flows for key activities and workflows for its production operations, with the ultimate goal of improved asset performance. In response to early water breakthrough, a study was commissioned to investigate whether smart completions that use down-hole internal control valves (ICVs) could provide a range of fluid-flow control options to enhance reservoir sweep efficiency, reduce produced water, and increase well life. This paper describes the strategy and process to identify production and injection wells best suited for intelligent well completions in the Sabriyah field, Mauddud reservoir. The goal is to control zonal injection and production rates to reduce uneven water fronts, sweep and produce bypassed oil, postpone water breakthrough, and extend well life, thus boosting oil production while optimizing water handling at the surface. The study demonstrates excellent potential for down-hole control to significantly improve operations in the water injection areas.
