CDMA mobile communication system performance analysis tools for network parameter planning (2002)

This paper presents a CDMA mobile system performance analysis tools (CPAT) for network parameter planning. In real traffic distributed environment, the CPAT collects the radio link related data as well as handoff related messages, and analyzes the CDMA system performance. The mobile loopback call, which is recommended as a service option standard, is used for logging data during the system test. The analysis tools consist of the analysis data processor (ADP) and the statistical analysis tool (SAT). The ADP analyzes the radio link related performance such as frame error rate, cell received Eb/No of reverse link, as well as reverse link power control, etc. The SAT provides softer/soft/hard handoff statistics such as number of handoff and handoff duration per mobile station, and handoff statistics per cell.
Symmetry and structure of reflection matrices of celestial bodies with particulate surfaces (2016)

The polarization of electromagnetic radiation reflected by a particulate surface is determined by a four by four reflection matrix. Symmetry relations are quite common for such reflection matrices. The reciprocity and mirror symmetry relations are combined to derive a third symmetry relation. These three relations are used to simplify reflection matrices for a variety of special directions of incident and reflected radiation. We show that some elements of the reflection matrix can vanish or equal other elements that have the same or opposite sign. Several applications of the results for studies of particulate surfaces and atmospheres above them are pointed out.
Current surgical treatment of valvular heart disease. (1995)

Surgery for valvular heart disease has undergone important refinements during the past several years. The general indications for valvular surgery are the presence of symptoms that interfere with the patient's lifestyle and that cannot be controlled with medical therapy, and indications of a threat to continued survival, such as angina, dyspnea, effort syncope or progressive impairment of ventricular contractility. Infective endocarditis may also be an indication for valvular surgery in patients with congestive heart failure, recurrent embolism, persistent infection despite antibiotic therapy, large vegetations or progressive conduction defects. Surgical procedures for the treatment of valvular heart disease include reconstruction techniques and valve replacement procedures. Reconstructive surgery minimizes the amount of materials that must be implanted. Advances in myocardial preservation have reduced the risk of such complex cardiac surgical procedures as multiple valve replacements and valve replacements combined with coronary artery bypass surgery. Follow-up care is important to monitor valve function, fluid balance and anticoagulation.
Structure and function of milk allergens (2001)

Proteins (CMP) involved in milk allergy are numerous and heterogeneous, with very few structural or functional common features. This heterogeneity is complicated by their genetic polymorphism, resulting in several variants for each protein. These variants are characterized by point substitutions of amino acids or by deletions of peptide fragments of varying size or by post-translational modifications such as phosphorylation or glycosylation. All of these modifications may affect allergenicity. No common molecular structure can be associated with allergenicity, although some homologous regions such as casein phospho-peptides can explain an IgE cross-reactivity. Three-dimensional structure is an important feature in CMP allergenicity but denatured and linear epitopes are also involved. Epitopes are numerous and widely spread along the CMP molecule. They may be located in hydrophobic parts of the molecule where they are inaccessible for IgE antibodies in the native conformation of the protein but become bioavailable after digestive processes. Peptides as short as ca. 12-14 amino acid residues may account for a significant part of the allergenicity of the whole molecule, which justifies the need to be careful before proposing any CMP hydrolysate for highly allergenic children.
Automation in clinical microbiology. (1992)

Automation was introduced into the clinical microbiology laboratory in the 1960s but initially met with limited success. Today, instruments are an integral part of many clinical laboratories and are used for microbial detection, identification, and susceptibility testing; detection of positive blood cultures; screening urine samples for potential pathogens; and assaying levels of antimicrobial agents in body fluids. Automation has allowed more rapid diagnosis and elimination of the subjective interpretation of many manual tests. In addition, in some cases, automated tests are more sensitive and specific than manual techniques. However, automated testing often is more expensive than manual testing and is associated with the possibility of mechanical failure. Automation will continue to be an important part of the clinical microbiology laboratory and in the future will include more molecular biology technologies, such as the polymerase chain reaction. Perhaps practical applications of flow cytometry will be identified.
Aircraft Aerodynamic Parameter Detection Using Micro Hot-Film Flow Sensor Array and BP Neural Network Identification (2012)

Air speed, angle of sideslip and angle of attack are fundamental aerodynamic parameters for controlling most aircraft. For small aircraft for which conventional detecting devices are too bulky and heavy to be utilized, a novel and practical methodology by which the aerodynamic parameters are inferred using a micro hot-film flow sensor array mounted on the surface of the wing is proposed. A back-propagation neural network is used to model the coupling relationship between readings of the sensor array and aerodynamic parameters. Two different sensor arrangements are tested in wind tunnel experiments and dependence of the system performance on the sensor arrangement is analyzed.
Conditional Independence of Events (1979)

In setting up a probability model for a system under study, the modeler utilizes all available prior knowledge about the system to determine probability assignments to appropriate events. This knowledge may be obtained from systematic statistical study, or from mathematical deductions based on assumptions supported by experience or experiment, or, less formally, from the judgment of a decision maker. These probability assignments serve to determine a prior probability measure. The probability P(A) of an event A provides a measure of the likelihood of the occurrence of this event.

Nonspecific, Nested Suppression PCR Method for Isolation of Unknown Flanking DNA (2000)

We report the development of a simple, sensitive and robust two-step PCR method for the isolation of unknown sequences flanking characterized regions of genomic DNA or cDNA. The method requires 100 bp or less of a known sequence upstream of an oligonucleotide primer binding site. A first round of suppression PCR is conducted at low stringency with a polymerase lacking exonuclease activity to generate a mixture of products including fragments of the desired flanking sequence that are often greater than 1 kb in length. The desired fragments are then amplified from the mixture in a second round of suppression PCR using an extended oligonucleotide in combination with a polymerase exhibiting exonuclease activity. These fragments are subsequently identified by hybridization with the 100 bp of known sequence or simply by cloning and sequencing. The method is widely applicable and allows isolation of novel cDNA from very low abundance transcripts.
Deployment of the GMPLS control plane for grid applications in experimental high-performance networks (2006)

In this article we present a review of the latest activities in recent experimental high-performance optical networks such as ultrascience network (USN), dynamic resource allocation via GMPLS optical network (DRAGON), and circuit-switched high-speed end-to-end transport architecture (CHEETAH). We compare the control and management approaches adopted in each of these networks and analyze their capabilities vis-a-vis the functional requirements of grid computing applications. Grid computing is increasingly on the rise to meet the massive processing and storage demands of a new class of e-science physics applications that may generate and require the processing of data sets reaching terabytes per day. The requirements of these applications challenge the limitations of the networking technologies that are in place today. In particular, the area of network management and control is undergoing significant developments in order to meet the demands of these applications. It is the purpose of this article to share our experiences in the deployment of the GMPLS control plane in these experimental optical networks. It is our belief that these and similar efforts will result in significant progress toward enabling connection-oriented high-performance networking. This new paradigm will encompass grid computing applications as well as commercial, health, and entertainment services, thus making it useful to the public at large.
Diabetes, Intermittent Claudication, and Risk of Cardiovascular Events: The Framingham Study (1989)

The impact of diabetes on intermittent claudication was examined in 1813 men and 2504 women with 34-yr follow-up data in the Framingham study. For both sexes, diabetes was associated with a two- to threefold excess risk of intermittent claudication compared with its absence. A pronounced excess risk was also observed in subjects on oral hypoglycemic therapy and in women receiving insulin. Although diabetes was often associated with an atherogenic-risk profile, controlling for age and several concomitant risk factors failed to eliminate the association with intermittent claudication. Those who developed both intermittent claudication and diabetes were at an especially high risk of incident cardiovascular events. In women, the risk of coronary heart disease, stroke, and cardiac failure was increased 3-4 times when diabetes and intermittent claudication occurred together compared with when either condition existed alone. In diabetic men, the presence of intermittent claudication doubled the risk of stroke, and cardiac failure was approximately 3 times more likely in subjects with both conditions compared with either alone. We conclude that diabetes is an important risk factor for intermittent claudication, which in turn confers a serious prognosis for subsequent cardiovascular outcomes in the patient with diabetes.

A hybrid algorithm for finding minimal unsatisfiable subsets in over-constrained CSPs (2011)

Minimal Unsatisfiable Subsets (MUSes) are the subsets of constraints of an overconstrained constraint satisfaction problem (CSP) that cannot be satisfied simultaneously and therefore are responsible for the conflict in the CSP. In this paper, we present a hybrid algorithm for finding MUSes in overconstrained CSPs. The hybrid algorithm combines the direct and the indirect approaches to finding MUSes in overconstrained CSPs. Experimentation with random CSPs reveals that the hybrid approach is not only quite efficient but when operating under a time bound it finds a more representative set of MUSes. © 2011 Wiley Periodicals, Inc.
Modeling and Parameter Identification of Harmonic Drive Systems (1998)

The unique performance features of harmonic drives, such as high gear ratios and high torque capacities in a compact geometry, justify their widespread industrial application. However, harmonic drive can exhibit surprisingly more complex dynamic behavior than conventional gear transmission. In this paper a systematic way to capture and rationalize the dynamic behavior of the harmonic drive systems is developed. Simple and accurate models for compliance, hysteresis, and friction are proposed, and the model parameters are estimated using least-squares approximation for linear and nonlinear regression models. A statistical measure of variation is defined, by which the reliability of the estimated parameter for different operating condition, as well as the accuracy and integrity of the proposed model is quantified. By these means, it is shown that a linear stiffness model best captures the behavior of the system when combined with a good model for hysteresis. Moreover, the frictional losses of harmonic drive are modeled at both low and high velocities. The model performance is assessed by comparing simulations with the experimental results on two different harmonic drives. Finally, the significance of individual components of the nonlinear model is assessed by a parameter sensitivity study using simulations.

This cortisol rise was deduced to be caused by sleep deprivation as a result of rapidly rotating shift patterns.
Determination of growth-coupling strategies and their underlying principles (2019)

Maximizing the minimally guaranteed production rate at a medium growth rate is an attractive principle for the identification of strain designs that couple growth to target metabolite production. Moreover, it allows for controlling the inevitable compromise between growth coupling strength and the retaining of microbial viability. With regard to the corresponding metabolic principles, generating a dependency between the supply of global metabolic cofactors and product synthesis appears to be advantageous in enforcing strong GC for any metabolite. Deriving such strategies manually, is a hard task, due to which we suggest incorporating computational metabolic network analyses in metabolic engineering projects seeking to determine GC strain designs.

RF LDMOSFET with graded gate structure (2003)

This paper describes a new RF LDMOS with a graded structure. It enables a very thin gate oxide to be used in the channel region to achieve high transconductance, but at the gate edges, the polysilicon is lifted off to more than 3 times that thickness, and thus the parasitic capacitance values C/sub gd/ and C/sub gs/ are significantly reduced. This improves the RF output power, gain and the cut-off frequency. Due to the release of the electric field in the gate edge, a sufficiently high breakdown voltage can be realized with very thin gate oxide.
Preclinical Assessment of Inflammatory Pain (2015)

While acute inflammation is a natural physiological response to tissue injury or infection, chronic inflammation is maladaptive and engenders a considerable amount of adverse pain. The chemical mediators responsible for tissue inflammation act on nociceptive nerve endings to lower neuronal excitation threshold and sensitize afferent firing rate leading to the development of allodynia and hyperalgesia, respectively. Animal models have aided in our understanding of the pathophysiological mechanisms responsible for the generation of chronic inflammatory pain and allowed us to identify and validate numerous analgesic drug candidates. Here we review some of the commonly used models of skin, joint, and gut inflammatory pain along with their relative benefits and limitations. In addition, we describe and discuss several behavioral and electrophysiological approaches used to assess the inflammatory pain in these preclinical models. Despite significant advances having been made in this area, a gap still exists between fundamental research and the implementation of these findings into a clinical setting. As such we need to characterize inherent pathophysiological pathways and develop new endpoints in these animal models to improve their predictive value of human inflammatory diseases in order to design safer and more effective analgesics.
Tension control of a two drum winder using paper tension estimation (2005)

Sheet tension control is crucial in the paper winding process in order to get properly formed shipping roll(s) produced on the winder. Typically, the tension loop uses load cells as tension sensors, which are expensive and require frequent maintenance and calibration. This paper develops two new tension estimators for a two drum, electric braking generator, production winder, based on unwinding and rewinding variables, respectively. The estimators consider all the essential dynamic, friction, and inertial variation effects. Both estimators are evaluated in typical trapezoidal winder operating cycles. Multiple sensitivity analyses show that the proposed estimators are robust to normal parameter variations, and give stable and precise sheet tension control without the use of load cell tension loops
Evidence for the Direct Effect of Adrenergic Drugs on the Cerebral Vascular Bed of the Unanesthetized Goat (1973)

Despite considerable research, the question of whether adrenergic drugs exert direct effects on the cerebral circulation has remained unresolved. With the development of a method for monitoring continuously the entire blood flow to one hemisphere in the unanesthetized goat, we have been able to study this problem directly. The effects of epinephrine, norepinephrine, and isoproterenol administered by close intra-arterial injection were investigated in 15 goats in which an electromagnetic flowmeter had been implanted previously on the internal maxillary artery, which, in this animal, provides the sole blood supply to a hemisphere. Both epinephrine and norepinephrine (0.1 to 5.0 µg) produced dose-dependent reductions in cerebral blood flow, a decrease of 55 ± 3% (SEM) occurring with the highest dose. Alpha receptor blockade of the ipsilateral hemisphere with phenoxybenzamine totally or partially abolished this cerebral vasoconstriction. Isoproterenol (0.01 to 1.0 µg) produced dose-dependent increases in cerebral blood flow, an increment of 75 ± 6% occurring with the highest dose. Beta blockade with propranolol totally or partially abolished the cerebral vasodilation induced by isoproterenol. Thus, epinephrine, norepinephrine, and isoproterenol exert powerful direct effects on the cerebral circulation of the unanesthetized goat, and these effects appear to be mediated by alpha and beta receptors.
Viscoelastic Properties of Homopolymers and Diblocic Copolymers of Polybutadiene and Polyisoprene. (1978)

Three diblock copolymers of cis-1-4 polyisoprene (IR) and 1-4 polybutadiene (BR) have been studied in dynamic mechanical experiments, transmission electron microscopy and thermomechanical analysis. The block copolymers had molar ratios of 1/2, 1/1 and 2/1 for the isoprene and butadiene blocks. Homopolymers of polybutadiene and polyisoprene with various diene microstructures were also examined using similar experimental methods. Results indicate that in all three copolymers the polybutadiene and polyisoprene blocks are essentially compatible, whereas blends of homopolymers of similar molecular weights and microstructures were incompatible.

Overview of cardiac pathology in relation to anthracycline cardiotoxicity. (1978)

A review is presented of cardiac pathologic changes associated with acute and chronic toxicity of anthracyclines. These changes consist of cardiac dilatation, degeneration and atrophy of the muscle cells, and interstitial edema and fibrosis. The degeneration of cardiac muscle cells is a complex phenomenon that involves the myofibrils, the nucleus, the mitochondria and the membrane systems of the T-tubules, the sarcoplasmic reticulum, and the intercellular junctions. The pathogenesis of these alteration is discussed in terms of the biochemical effects of anthracyclines.
