A practical guide to help you manage your hypertensive patients. (1978)

Collagen is an important component of the extracellular matrix (ECM) and plays an important role in normal tissue maturation and in pathological processes such as atherosclerosis and myocardial infarction. The diagnostics of the latter diseases using MRI could strongly benefit from the use of collagen-specific contrast agents. The current study aimed to develop a bimodal liposomal MR contrast agent that was functionalized with CNA35, a collagen adhesion protein of the Staphylococcus aureus bacterium. The liposomes were characterized in terms of CNA35 protein conjugation and loading. The overall morphology was assessed with DLS and cryo-TEM, while cryo-TEM tomography was used to visualize the protein coverage of the liposomes. The binding properties of the contrast agent were investigated using a fluorescence assay based on the rhodamine content of the liposomes. The bulk relaxivity was determined using regular relaxometry while the MR-properties of liposomes in their bound state were studied using NMR depth profiling. This CNA35 functionalized contrast agent and the set of in vitro experiments we performed indicate the potential of this technology for in vivo molecular imaging of collagen.

Generation reliability impacts of industry-owned distributed generation sources (2004)

The successful integration of industry-owned distributed generation (DG) sources into the power systems of deregulated electric utilities involves fundamental long-term issues, conflicting objectives and important uncertainties. Presently, corporate financial difficulties, public environmental concern and deregulation of electric utility industry are making base load thermal and nuclear plants more and more difficult to build. As a result, industry-owned distributed generator is a source of electrical energy commonly considered as a part of the solution to this problem. Most of the available literature on DG has focused on its economic and interconnection impacts on a utility or on a ratepayer, or on an owner of distributed generating unit. What is missing from existing DG analysis is a relatively simple and understandable method examining the generation reliability impacts of industry-owned DG sources on utility systems. This paper presents industry schedule related models for modeling distributed generators for use in conventional generating capacity reliability assessment. The developed models are illustrated using the Institute of Electrical and Electronics Engineers (IEEE) Reliability Test System (RTS).
Interstitial Subcutaneous Emphysema complicating Pulmonary Tuberculosis (1941)

protected from the acid gastric contents. The attainmient of a low acid level is only one method of realizing this; such an effect is most completely attained by neutralization of the gastric juiceas soon as it is secreted, a process which can only be carried out effectively at present by means of the continuous intragastric drip apparatus. This, however, is not a practicable method for the vast majority of cases, and should be re-served for those of especial severity.
Carboxylic and <i>O</i>-acetyl moieties are essential for the immunostimulatory activity of glucuronoxylomannan: a novel TLR4 specific immunostimulator from <i>Auricularia auricula-judae</i> (2018)

This study established the comprehensive repeating unit structure of immunologically active glucuronoxylomannan (AAPS) from wood ear mushroom, Auricularia auricula-judae. We identified Toll-like receptor 4 (TLR4) as a critical receptor involved in AAPS-induced macrophage activation to secrete pro-inflammatory cytokines. Molecular modeling data and chemical modifications of AAPS revealed that both carboxylic and acetyl moieties of AAPS are equally essential in TLR4 binding to exert in vitro immunostimulatory activity.
Recent advances in the management and prophylaxis of respiratory syncytial virus infection (2001)

Respiratory syncytial virus (RSV) infection is an important cause of morbidity, particularly in prematurely born infants who have had chronic lung disease. Current therapy is essentially supportive. Overall, the results of randomized trials do not support the use of bronchodilators, corticosteroids or Ribavirin. Nitric oxide and exogenous surfactant may improve the respiratory status of those infants who require ventilatory support. Nosocomial infection can be reduced by appropriate handwashing. There is no safe and effective vaccine for use in infants. Immunoprophylaxis reduces hospitalization and requirement for intensive care. Palivizumab, a humanized monoclonal antibody, is preferred to RSV immune globulin as the immunoprophylactic agent. Immunoprophylaxis should be reserved for infants at highest risk of severe respiratory syncytial virus infection. if this strategy is to be used most cost-effectively.
Cyclitols. Part XXII. Synthesis of some mannosyl- and mannosylmannosyl-myoinositols, and of galactinol (1966)

Two diastereoisomeric α-D-mannopyranosylmyoinositols have been synthesised in poor yield from (±)-1,4,5,6-tetra-O-acetylmyoinositol by the Königs–Knorr reaction. Each compound was then converted into the 1 → 6-linked mannosylmannosyl derivative. Galactinol [1-O-α-D-galactopyranosyl-(1R)-myoinositol] was synthesised in a similar way. Acid reversion of mannose gives mainly α-(1 → 6)-linked oligosaccharides.
The Relationship of Alterations in Systolic Time Intervals to Ejection Fraction in Patients with Cardiac Disease (1970)

The relationships between the systolic time intervals determined from simultaneous recordings of the electrocardiogram, the phonocardiogram, the carotid arterial pulse tracing, and direct measures of left ventricular performance as assessed angiographically by measurement of left ventricular stroke volume (SV), end-diastolic volume (EDV), and ejection fraction (EF) were studied in 68 patients with a wide variety of cardiac diseases. The systolic intervals, the pre-ejection period (PEP), the left ventricular ejection time (LVET), and the ratio PEP/LVET, each correlated significantly with angiographically determined EF and EDV. Closest correlation was observed between PEP/LVET and EF (r = -0.90). The systolic intervals correlated only slightly with the angiographically determined SV. These data lend additional evidence supporting the use of systolic time intervals as a non-invasive measure of left ventricular performance in patients with cardiac disease.
Access Point Design with a Genetic Algorithm (2012)

The interest in deploying local wireless networks has increased in the corporate environment, in recent years, as a result of several improvements in their features. Nevertheless, there are some problems caused by inadequate positions of access points (APs) which overload some cells of the total area to be covered. Some strategies of AP positioning aim only at covering the environment. Some aspects, such as, the number of users per AP and reducing the distance from the users to an AP, could be objective function parameters in the network optimization problem. This article presents a novel model to AP design, where the area covered and the users connected are maximized, and the number of APs is minimized. Two different algorithms to deal with the AP design are presented, the greedy search heuristic and a genetic algorithm. Three experimental studies with different areas to be covered were conducted. in all of them, both algorithms reached their targets, i.e., all the grid area was covered and all users were served.
Galvanic Skin Response as a Measure of Soldier Stress (2007)

Abstract : In the ever-increasing realm of Soldier systems, one factor remains fairly constant: the human factor. The use of multiple high-tech and increasingly complex systems is intended to add capabilities to Soldiers and to reduce stress and workload. However, these systems may add increased levels of stress and workload onto Soldiers who are already at heightened levels of each because of the environments in which the systems are employed. To gauge what levels of stress and workload are being impinged upon these Soldiers, researchers have used a small number of tools at their disposal. The two primary tools used are self-report surveys and salivary amylase. Surveys are quick and cheap but subjective, while salivary amylase tests are objective but time-consuming, intrusive, and expensive. As requirements increase to incorporate larger numbers of high-tech and more complex systems with Soldier-in-the-loop (SIL) systems, researchers will need a method to gather stress data in an accurate, timely, and less intrusive manner. This report discusses the use of a third method to measure Soldier stress: galvanic skin response (GSR). The first step of this process compared the survey method with the GSR method to determine if GSR data are similar to survey stress data in terms of statistics and trends. The ultimate goal of the research (this phase and ensuing research) is to determine if the GSR method is a suitable middle ground between the survey method and the salivary amylase method. GSR has the potential to provide researchers with a tool for objectively measuring Soldier stress that is quick, effective, and unobtrusive during research, training, and operational conditions. Stress levels were tested with soldiers using a head-tracked sensor suite (HTSS), aided target recognition technology, and a crew-aiding behavior interface. Results of the survey-GSR comparison and recommendations for ensuing research are presented.

A Tunable CMOS UWB Pulse Generator (2006)

A tunable ultra-wideband (UWB) pulse generator is designed and simulated with standard 0.18-μm CMOS technology. By using a voltage controlled delay line (VCDL) technique, the proposed UWB pulse generator can adjust the pulse width, adding flexibility for use with different UWB applications. Moreover, each peak of the proposed UWB pulse is separately controlled so that it complies with the FCC regulation. The proposed UWB pulse generator achieves the fifth-order derivative of the Gaussian pulse and can tune the pulse width from 0.38-ns to 4-ns. In particular, the maximum and minimum pulse widths comply with 3 - 10 GHz and sub-GHz FCC regulations, respectively.
A 6.25-Gbps 4-tap low-power decision feedback equalizer in 0.13&#x00B5;m CMOS technology (2013)

A half-rate 4-tap decision feedback equalizer (DFE) is implemented in 0.13μm CMOS technology for low-power I/O links. Modified current-mode logic (CML) latches with PMOS loads are used in the new proposed DFE to achieve better power and area efficiency. The proposed DFE consumes only 1.914mW from a 1.2V supply when equalizing 6.25Gb/s data passing through a simulated low-pass channel with 18 dB of loss at 3.125 GHz, which is 39.5% lower than the traditional design with resistor loaded CML latches.
Glottal pulse alignment in voiced speech for pitch determination (1993)

A method for phase tracking the glottal pulses in voiced speech to obtain pitch estimates is described. The phase alignment of the glottal pulses is accomplished by correlating the speech waveform with a time-varying adaptive filter matched to previous glottal pulses. The correlation is scored by a pseudometric which is constructed to be invariant under affine transformations of the incoming waveform. The instantaneous pitch period estimates obtained by the glottal pulse alignment algorithm are comparable with hand-marking.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characterization of heat eluates of human malignant tissues. (1979)

Eluates of 13 malignant and 17 normal tissues were prepared at 56 degrees C using the continuous flow technique. Albumin was detected in all the eluates. IgG, IgA, C3 or haptoglobin were detected in most of the malignant and some of the normal tissues. Carcinoembryonic antigen, beta 2-microglobulin, alpha 1-antitrypsin or alpha 1-antichymotrypsin were detected in some of the eluates of the malignant tissues only. IgM, IgD, C1q, C4, Cl-INH, alpha 1-macroglobulin, beta 2-lipoprotein, fibrinogen and alpha 1-foetoprotein were not detected in any of the eluates. The ratio of the concentration of albumin to the concentration of IgG was similar in extracts and eluates of all the normal tissue and in 3 of the malignant tissues indicating non-specific binding of IgG.
Multi-agent system vulnerability detector for a secured E-learning environment (2016)

Information and communication systems have several security vulnerabilities. In addition, conventional security software requires tuning effort and may not be able to detect many web attacks. For this reasons, security becomes a worldwide objective to many technological systems including Learning Management Systems (LMSs) such as Moodle. In this work, we propose a secured multi agent system (MAS) with an interceptor IIS module (IIISM) which denies malicious user access by adding a security layer to any web application including the LMS Moodle environment. The IIISM extends the IIS Server and listens to any http request targeting the web application and the LMS Moodle. While, the analysis and the design of the MAS architecture are based on the Gaia methodology, the agents were implemented using the JADE agents' middleware. This security layer overcomes the hacker attack based on the SQL injection and the cross site scripting for Moodle environment. In a first scenario, a student is requesting a course, the MAS validate this request, and the web page is displayed normally. A second scenario presents the URL and form based for the SQL injection attack by a hacker. The MAS agents detect the attack and and they respond by a denial of access to this malicious user. Moreover, this proposed security layer can be easily extended to include other security detection modules which correspond to common web vulnerabilities.
Enhancing the Electrocatalytic Property of Hollow Structured Platinum Nanoparticles for Methanol Oxidation Through A Hybrid Construction (2014)

The integration of different components into a hybrid nanosystem for the utilization of the synergistic effects is an effective way to design the electrocatalysts. Herein, we demonstrate a hybrid strategy to enhance the electrocatalytic property of hollow structured Pt nanoparticles for methanol oxidation reaction. This strategy begins with the preparation of bimetallic Ag-Pt nanoparticles with a core-shell construction. Element sulfur is then added to transform the core-shell Ag-Pt nanostructures into hybrid nanodimers consisting of Ag2S nanocrystals and remaining Pt domains with intact hollow interiors (Ag2S-hPt). Finally, Au is deposited at the surface of the Ag2S domain in each hetero-dimer, resulting in the formation of ternary Ag2S-Au-hPt nanocomposites with solid-state interfaces. The ternary nanocomposites exhibit enhanced electrocatalytic property toward methanol oxidation due to the strong electronic coupling between Pt and other domains in the hybrid particles. The concept might be used toward the design and synthesis of other hetero-nanostructures with technological importance.
Real-Time Vehicle Signal Lights Recognition with HDR Camera (2016)

Light signal recognition is one of the key issues in autonomous vehicle. Unlike normal object detection and recognition, which can be done by using different sensors, light signal recognition is naturally a computer vision problem. Although commercialized ADAS (Advanced Driving Assistance System) products, such as mobileye, could be used for rear-end collision warning, a cost-effective approach is still needed. In this paper, we have developed a novel two-stage approach to detect vehicles and recognize signal lights from a single image in real-time. Distinct from current state-of-the-art light recognition algorithms, we adopted a HDR (High Dynamic Range) camera instead of a color camera. Taking advantage of the different dynamic range of a HDR camera, the detection of a vehicle and the recognition of the signal light have been done in bright and dark channels, respectively. Furthermore, unlike previous approaches where pair taillight has to be extracted explicitly, we use detected vehicle region instead. On a large database, "Lights Patterns" (LPs) are learned by a multi-layer perception neural network. The robustness and efficiency of the proposed approach has been verified by the experimental results conducted on some real on-road videos.
Agent-based load balancing on homogeneous minigrids: macroscopic modeling and characterization (2005)

In this paper, we present a macroscopic-characterization of agent-based load balancing in homogeneous minigrid environments. The agent-based load balancing is regarded as agent distribution from a macroscopic point of view. We study two quantities on minigrids: the number and size of teams where agents (tasks) queue. In macroscopic modeling, the load balancing mechanism is characterized using differential equations. We show that the load balancing we concern always converges to a steady state. Furthermore, we show that load balancing with different initial distributions converges to the same steady state gradually. Also, we prove that the steady state becomes an even distribution if and only if agents have complete knowledge about agent teams on minigrids. Utility gains and efficiency are introduced to measure the quality of load balancing. Through numerical simulations, we discuss the utility gains and efficiency of load balancing in different cases and give a series of analysis. In order to maximize the utility gain and the efficiency, we theoretically study the optimization of agents' strategies. Finally, in order to validate our proposed agent- based load balancing mechanism, we develop a computing platform, called simulation system for grid task distribution (SSGTD). Through experimentation, we note that our experimental results in general confirm our theoretical proofs and numerical simulation results from the proposed equation system. In addition, we find a very interesting phenomenon, that is, agent-based load balancing mechanism is topology-independent.
Shield Construction for Extended Field Therapy of Hodgkin's Disease (1969)

Recent trends toward higher doses and larger volumes in the treatment of lymphomas require careful shielding of adjacent normal tissues. The purpose of this discussion is to present the method used in the Radiation Therapy Department of the Presbyterian-St. Luke's Hospital, Chicago, for building lead shielding tailored to the individual patient. This method is accurate, uses inexpensive materials and tools, and is relatively simple. Protection of vital, normal structures in patients undergoing extended field therapy was provided by a variety of standard lead blocks of various sizes and shapes. None of these gave optimal or even very satisfactory protection. It quickly became apparent that shielding custom-tailored to the individual patient would be necessary to provide satisfactory shielding of normal structures. Templates for the lead shields are produced by the following method: With the patient and the shield-supporting satellite placed at identical distances from the focal spot as they will be from the source during therapy, a simulator film is taken with a film beneath the patient and a 1/2-inch chicken-wire grid placed immediately above the satellite (Fig. 1, A). This produces a roentgenogram of the patient with a magnified image of the grid superimposed (Fig. 2, A). A second roentgenogram is made with the film placed on the satellite immediately under the same chicken-wire grid (Fig. 1, B). This produces a filn showing only an unmagnified grid (Fig. 2, B). The area to be protected is then outlined by the radiotherapist on the simulator film of the patien with the superimposed magnified grid (Fig. 3, A) This outline is then reproduced on the plain filn with the unmagnified grid, using it as a reference (Fig. 3, B). This outline, reduced in size, represents the true size of the lead shields and can be used directly as the template for building the lead blocks. Initially, this template was used to cut the lead shield out of a solid lead block either by band-sawing, jigsawing, or milling. The extremely poor cutting qualities of lead, even when hardened by small percentages of various other metals, makes this method frustratingly slow and sometimes even dangerous. We have long since switched to our current method which employs the low melting point of lead. The template is taped to a 2-inch thick Styrofoam sheet, and an outline is cut out on a fine jigsaw. We have used the Dremel hobby jigsaw which has an adequate capacity for this purpose and makes a cut sufficiently fine to turn essentially right-angled corners. Styrofoam is used in making the patterns because it is easily dug out of the mold; a wood pattern might work well, but great care would be necessary in removing it from the plaster to avoid fracturing the mold. Two-inch-thick patterns, Styrofoam or otherwise, will yield lead blocks something slightly less than 2 inches thick which represent something over 4 mm h.v.l. shielding for cobalt-60 teletherapy.
Resolving CP Design Restrictions at an Australian Wharf: a Novel Marine Impressed Current CP System (2010)

Abstract This paper presents resolutions to cathodic protection (CP) design restrictions at an Australian 1km long steel-pile container wharf, requiring a 3,500A impressed current CP (ICCP) system. Rectifier locations were confined to ends of the wharf, while all cablework from rectifiers to anodes and piles had to be mounted underneath the dock. In a traditionally designed ICCP system using transformer-rectifier units (TRUs) and low-voltage/high-current DC distribution, these restrictions would result in cable cross-sections of up to 120mm2 per anode leg. Instead, a novel DC power distribution system was utilized, consisting of parallel channels of high-voltage/low-current Power Supply units (PSUs) feeding adjustable constant current into Current Multiplier DC/DC converters located close to anodes. Thus, power cables leading from PSUs could all be 1.0÷2.5mm2 twin-core cables, distributing 2A@300Vdc max towards each anode, where Current Multipliers transform it into 45A@9Vdc max. A single-anode prototype was developed as a proof-of-concept trial system, and then a full 77-anode ICCP system was constructed for the complete wharf corrosion protection. Major parameter values of the installed distribution cable network were considerably reduced – the average cable cross-section size by a factor of 30, the total cable weight by 12, and the total cable material and installation costs by 15÷20. Total system power consumption from AC-mains was cut down by 55%.

Structure‐Property Relations for Pyrolytic Graphite (1964)

The mechanical and physical properties of pyrolytic graphite are closely related to the structure produced during its deposition. It is shown how various features of the deposited structure can be predicted with some accuracy. These features include the structure of isolated nodules, the influence of various substrate conditions, and the effects of continuous nucleation. The effect of these structures on properties is discussed and the relation of the residual stress state to the deposition conditions is explained.
