Regulation of Tissue Oxygenation (2011)

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 in their vicinity falls to a critical level of about 1 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2. In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
Glial fibrillary acidic protein (GFAP) from goldfish: Its localisation in visual pathway (1989)

An intermediate filament fraction, isolated from goldfish brain, contains a prominent protein having a molecular weight of 51 kDa. In normal goldfish visual pathway, this protein is present in tectum and tract, but not in optic nerve. A polyclonal antibody raised to this protein clearly labels ependymal glial profiles in tectum and parallel processes in the tract, whereas optic nerve is unlabelled; Müller fibres in the retina are also labelled. A similar, but less prominent, pattern of staining is observed with antibodies, raised elsewhere, against glial fibrillary acidic protein from human and porcine. These results suggest that the 51 kDa protein is a GFAP, demonstrate the heterogeneity of astrocytes in goldfish visual pathway, and are consistent with the idea that GFAP is well conserved in vertebrate phylogeny.
Network Management and Congestion in the U.S. Telecommunications Network (1981)

Several significant steps have been taken to respond to the need for better network management for the evolving U.S. telecommunications network. The current approach provides an economical balance between automatic and manual network management capabilities. With the rapid introduction of Stored Program Controlled (SPC) switching systems and the Common Channel Interoffice Signaling (CCIS) system, more emphasis is being placed on continued improvement in automatic controls. Advances in manual network management controls and real-time surveillance capabilities have been accomplished primarily through the introduction of computer-based systems which support the operation of centralized Network Management Centers (NMC's). Also, new controls are introduced for forthcoming SPC-CCIS network services. The evolution, status, and future needs for network management of the coterminous U.S. telecommunications network are presented. An extensive bibliography is given.
A Peak Reduction Scheduling Algorithm for Storage Devices on the Low Voltage Network (2014)

Reinforcing the Low Voltage (LV) distribution network will become essential to ensure it remains within its operating constraints as demand on the network increases. The deployment of energy storage in the distribution network provides an alternative to conventional reinforcement. This paper presents a control methodology for energy storage to reduce peak demand in a distribution network based on day-ahead demand forecasts and historical demand data. The control methodology pre-processes the forecast data prior to a planning phase to build in resilience to the inevitable errors between the forecasted and actual demand. The algorithm uses no real time adjustment so has an economical advantage over traditional storage control algorithms. Results show that peak demand on a single phase of a feeder can be reduced even when there are differences between the forecasted and the actual demand. In particular, results are presented that demonstrate when the algorithm is applied to a large number of single phase demand aggregations that it is possible to identify which of these aggregations are the most suitable candidates for the control methodology.
Verification of POI and Location Pairs via Weakly Labeled Web Data (2015)

With the increased popularity of mobile devices and smart phones, location-based services (LBS) have become a common need in our daily life. Therefore, maintaining the correctness of POI (Points of Interest) data has become an important issue for many location-based services such as Google Maps and Garmin navigation systems. The simplest form of POI contains a location (e.g., represented by an address) and an identifier (e.g., an organization name) that describes the location. As time goes by, the POI relationship of a location and organization pair may change due to the opening, moving, or closing of a business. Thus, effectively identifying outdated or emerging POI relations is an important issue for improving the quality of POI data. In this paper, we examine the possibility of using location-related pages on the Web to verify existing POI relations via weakly labeled data, e.g., the co-occurrence of an organization and an address in Web pages, the published date of such pages, and the pairing diversity of an address or an organization, etc. The preliminary result shows a promising direction for discovering emerging POI and mandates more research for outdated POI.
A clinical, renal and immunological assessment of Surface Modifying Additive Treated (SMART™) cardiopulmonary bypass circuits (2005)

Biocompatible cardiopulmonary bypass (CPB) circuits aim to reduce contact activation and its physiological consequences. We investigated the hypothesis that use of Surface Modifying Additive (SMA)-treated circuits (Sorin Group Ltd) compared with non-SMA circuits would be associated with preservation of blood pressure during CPB and modulation of perioperative subclinical renal function (urinary alpha-1-microglobulin (alpha-1-m)) and plasma and urinary cytokine changes. In a study of low-risk CABG patients (n=40), randomized to SMA (n=20) versus non-SMA circuits (n=20), we found better preserved blood pressure at CPB initiation in SMA patients (p <0.05), particularly in ACE-inhibited SMA patients (n =11) versus ACE-inhibited non-SMA patients (n =10) (p <0.05). Plasma anti-inflammatory IL-10, as well as urinary alpha-1-m, were elevated 48 hours postoperatively (p <0.05). SMA patients also had lower blood loss (p <0.05). SMA circuits have some clinical benefit, especially in ACE-inhibited patients.
<title>Secure communication using chaotic synchronization</title> (1993)

Secure communication via chaotic synchronization of homogeneous driving systems of the Lorentz and Rossler type is demonstrated for AM, FM, SSB, and FSK modulations. Signal injection is additive. Actual AM, FM, SSB, and FSK signals were digitized using a 1 and 10 Mhz A/D. Analysis techniques of post chaotic modulation include the power spectrum, information dimension, Lyapunov exponents, mutual information, and metric entropy. Further inspection of the rates of convergence of the receiver subsystems gives insight into the selection of signal to driving system power ratio. Power ratios for adequate embedding for each modulation type in the chaotic signal are discussed. Differences in demodulation accuracy for the Lorentz and Rossler systems are discussed. It is seen that all modulation types can be sufficiently masked using a range of power ratio settings. However, the dynamical fidelity of the demodulated signal is compromised for some cases.
Reducing Electricity Cost of Smart Appliances via Energy Buffering Framework in Smart Grid (2012)

To reduce the long term electricity cost of smart appliances (SAs) with deferrable operation time in smart grid, we propose a novel energy buffering framework to intelligently schedule the distributed energy storage (DES) for the cost reduction of SAs in this paper. The proposed energy buffering framework determines the action policy (e.g., charging or discharging) and the power allocation policy of the DES to provide DES power to proper SAs at proper time with lower price than that of the utility grid, resulting in the reduction of the long term financial cost of SAs. Specifically, we first formulate the optimal decision problem in the energy buffering framework as a discounted cost Markov decision process (MDP) over infinite-horizon. Then, we propose an optimal scheme for the energy buffering framework to solve the discounted cost MDP based on online learning approach. Extensive simulation results show that the proposed optimal scheme for the energy buffering framework can significantly reduce the long term financial cost comparing with the baseline schemes and the myopic scheme.
Networks and complexity (2002)

nderstanding complexity and broad systems-level frameworks in the life, physical and social sciences has turned, in recent decades, to issues of network dynamics. Although network analysis has matured over many decades, as in the field of social networks [e.g., 1], only recently have classes of statistical and mathematical models been developed of sufficient breadth and power to accommodate more unified theories as well as foundational questions of dynamics and emergent structure. For example, to identify sources of similarity across hundreds of networks collected across species, Skvoretz and Faust showed how new statistical models (discussed in this issue) could be used to evaluate whether structural differences vary by classes of relations, such as influence, grooming, and agonistic encounters, as opposed to species-specific variance The growth of the World Wide Web, staggering advances in computing power and diminishing computational complexity of network algorithms, and demonstrations of the robustness and ubiquity of networks fitting small-world models [3] helped spark much of the recent cross-disciplinary explosion in network analysis and modeling. In these contributions, balancing the social with the physical and life sciences, each team or researcher was asked to reflect on the role of networks and network dynamics in their primary research areas.

Analysis of cross-talk effect in SOI analog-digital mixed integrated circuits (2002)

With two-dimensional (2D) TIMA medici simulator, the systematic analysis of cross-talk behavior is presented for SOI analog-digital mixed integrated circuits. It is found that the buried-oxide becomes transparent with the increase of frequency and the noise coupling can be decreased to a large extent by contacting the substrate to the ground. At the same time, the efficiency of different strategies for reducing cross-talk such as trench isolation, capacitive guard ring and differential structure is studied. Besides, the effect of some extrinsic parameters on the cross-talk behavior is also given. The results can serve as a guideline for designing low-noise coupling SOI analog-digital mixed IC's.

Multiphase ZVS Active Clamp Boost Converter: DC and Dynamic Current Sharing (2012)

The active clamp boost converter (ACBC) has been analyzed, and a complete model has been obtained. It has been checked that it behaves as a voltage source with high input impedance. Because of this feature, this topology is suitable for multiphase design, where different stages share the load in a passive way, without any extra mechanism or components. The design of multiphase converters is simplified, particularly for a big number of phases, as no extra information must be processed. Steady-state current sharing has been studied as well as how component tolerances affect the current distribution. A simple design guide to select different components has been detailed, and, moreover, the conditions to achieve soft switching have been revised. To test passive current sharing, a two-phase ACBC has been built. It has been tested in open loop to prove that without any control loop or extra components, the load sharing is achieved.
Lumbosacral Arachnoiditis (1978)

One hundred patients with lumbosacral adhesive arachnoiditis documented either directly at surgery or by unequivocal myelography served as the basis for this report on the pathologic process. Nomenclature for this disease, involving radiculitis, arachnoiditis, and adhesive arachnoiditis, is proposed. The entity appears not to be rare, as previously thought, but common in patients with severe back and/or leg pain and functional incapacitation due to the failed back surgery syndrome. While true incidence and relationship to a combination of causal factors remains to be accurately documented, the importance of Pantopaque in contributing to this disease process appears to be quite significant.

A Novel Control Scheme for a Unified Power Flow Controller (2006)

In this paper real, reactive power and voltage balance of the UPFC system is analyzed. Two important results related to UPFC control has been obtained. First, it is indicated that the shunt converter provides all the required reactive power during the power flow changes if the UPFC bus voltage is constant. Second, the UPFC bus voltage can be controlled both from the sending side and from the receiving side. Based on the analysis a novel coordination controller is proposed here for a UPFC. The basic control strategy is such that the shunt converter of the UPFC controls the transmission line reactive power flow and the DC link capacitor voltage. The series converter controls the transmission line real power flow and the UPFC bus voltage. The real/reactive power coordination controllers in the UPFC control system can get good performance both during transient and stable conditions. Experimental works have been conducted to verify the effectiveness of the proposed control strategy
Analysis of a Simple, Multi-Receiver GPS Spoof Detector (2013)

GPS spoofing is a hot topic of late; technical discussions vary widely based upon the assumed capabilities and a priori knowledge of the spoofer. For a single GPS receiver, various methods to detect a spoofing event have been proposed in the literature. These range from simple ideas (e.g. monitoring the power levels of the GPS signals) to more complex concepts (e.g. looking for vestigial peaks in the correlator outputs) to the comparison to non- GPS signals (e.g. an IMU). Much of this prior work has been on the conceptual level with limited experimentation; little appears to have been done to analyze the resulting detection performance. The detector of interest here monitors the GPS signals using not one, but two or more receivers with their antennas at known relative positions. The assumption is that during a spoofing event these multiple receivers will receive the same spoofer RF signal in that the satellites’ characteristics (i.e. relative times of arrival) are identical at all of the antennas. With no spoofer present, each antenna would receive a unique RF signal, consistent with its position in space. The concept of the detector, then, is that the presence of spoofing is discernible from the near equivalence of the receivers’ receptions. While one could compare these multiple receptions at the RF level, we compare the position solutions across receivers, declaring a spoofing event if the resulting position solutions are too close to each other as compared to the (known) relative locations of the antennas. The primary advantage of such an approach is that the hypothesis test does not require receiver hardware modification or even access to software GPS methods; a separate processor could easily monitor the positions output from the receivers. In this paper we analyze such a detector from a Neyman-Pearson perspective assuming Gaussian statistics on the position solution data. We consider four cases: (1) two receivers with fixed (known) locations, (2) two receivers with fixed separation and known orientation (but unknown absolute position), (3) two receivers with fixed separation and unknown orientation, and (4) a three receiver example.
Photoinduced ionization of bovine serum albumin by holographic relaxation methods (1986)

Holographic relaxation spectroscopy (HRS) has been applied to the study of bovine serum albumin labeled with isothiocyanatoazobenzene (BSA-ABITC) in solutions of low ionic strength. Below 25 mM NaCl two relaxation rates are evident, one of which corresponds to the tracer diffusion rate for BSA while the other increases as the ionic strength is decreased. In the electrophoretic HRS experiment (EHRS), two components having the mobilities μ=2.59×10−4 cm2/V s) and μ=2.21×10−4 cm2/V s) are observed, but in this case the apparent diffusion coefficients are equal. These results are consistent with a model in which the absorption of light by the azobenzene group causes BSA-ABITC to change its net charge. The coupled diffusion of BSA, ionized BSA, counterion, and coions is adequately described by a simple theory based on the model of Lee and Schurr [J. Polym. Sci. 13, 873 (1975)].
