Behavioral modeling and digital predistortion of Power Amplifiers with memory using Two Hidden Layers Artificial Neural Networks (2010)

This paper presents a novel Two Hidden Layers Artificial Neural Networks (2HLANN) model for behavioral modeling and linearization of RF Power Amplifiers (PAs). Starting with a feedback loop principle model of a PA, an appropriate neural networks structure is deduced. This structure was then optimized to form a real valued and feed-forward 2HLANN based model capable of predicting the nonlinear behavior and the memory effects of wideband PAs. The validation of the proposed model in mimicking the behavior of a Device Under Test (DUT) is carried out in terms of its accuracy in predicting the output spectrum, dynamic AM/AM and AM/PM characteristics and the normalized mean square error. In addition, the 2HLANN model was used to linearize two 250 Watt peak-envelope-power Doherty PAs (DPAs) driven with 20 MHz bandwidth signals. The linearization of these DPAs using the 2HLANN enabled attaining an output power of up to 46.8 dBm and an average efficiency of up to 47.5% coupled with an Adjacent Channel Power Ratio higher than 50 dBc. When compared to a number of previously published behavioral and DPD schemes, the 2HLANN model demonstrated an excellent modeling accuracy and linearization capability.
Polyetherimide: A New Membrane‐Forming Polymer for Biomedical Applications (2002)

Membranes for biohybrid organs such as the biohybrid liver support system have to face 2 different environments, namely blood and tissue cells. Accordingly, the respective membrane surfaces must have optimal properties in terms of biocompatibility for blood or tissue. Flat membranes prepared by a phase inversion process from polyetherimide were modified by binding of tris-(hydroxymethyl)-aminomethane to obtain a surface with hydroxyl groups by binding of polyethylene imine to attach a hydrophilic macromolecule with amine groups useful as a spacer for later bonding of further ligands and by attachment of heparin. The binding of the different ligands was successful as monitored by different physicochemical methods. The blood response of plain polyetherimide was comparable to that of polyacrylonitrile, and it could be further improved by the binding of heparin. The tissue compatibility of polyetherimide and its different modifications was compared with commercial cell culture substrate membranes (Millicell) and found to be comparable for polyetherimide and even better after the modification with tris-(hydroxymethyl)-aminomethane. In conclusion, polyetherimide seems to be an interesting material for the production of membranes for application in biohybrid organ systems.
Correlation between carbohydrate structures on the envelope glycoprotein gp120 of.HIV-1 and HIV-2 and syncytium inhibition with lectins (1989)

The binding of 13 different lectins to gp120 partially purified from two HIV-1 isolates and one HIV-2 isolate was studied by in situ staining on electrophoretically separated and electroblotted HIV antigens. The lectins concanavalin A, wheat germ agglutinin, Lens culinaris agglutinin, Vicia faba agglutinin, Pisum sativum agglutinin and phytohaem(erythro)agglutinin bound to gp120 of all three isolates. The carbohydrate of gp120 recognized by lectins was thus arranged in at least four types of glycans: a high mannose type glycan, a bisected hybrid or complex type glycan, a biantennary fucosylated complex type glycan and a triantennary bisected complex type glycan. Only lectins which bound at least one of the four types of glycans were capable of inhibiting fusion of HIV-infected cells with CD4 cells by a carbohydrate-specific interaction with the HIV-infected cells. Thus, several different glycan structures may be implicated in CD4-gp120 binding.
Fully Packaged Carbon Nanotube Supercapacitors by Direct Ink Writing on Flexible Substrates (2017)

The ability to print fully packaged integrated energy storage components (e.g., supercapacitors) is of critical importance for practical applications of printed electronics. Due to the limited variety of printable materials, most studies on printed supercapacitors focus on printing the electrode materials but rarely the full-packaged cell. This work presents for the first time the printing of a fully packaged single-wall carbon nanotube-based supercapacitor with direct ink writing (DIW) technology. Enabled by the developed ink formula, DIW setup, and cell architecture, the whole printing process is mask free, transfer free, and alignment free with precise and repeatable control on the spatial distribution of all constituent materials. Studies on cell design show that a wider electrode pattern and narrower gap distance between electrodes lead to higher specific capacitance. The as-printed fully packaged supercapacitors have energy and power performances that are among the best in recently reported planar carbon-based supercapacitors that are only partially printed or nonprinted.
Liver-directed therapies in metastatic colorectal cancer. (2014)

Colorectal cancer (CRC) is a major health concern in the United States (US) with over 140,000 new cases diagnosed in 2012. The most common site for CRC metastases is the liver. Hepatic resection is the treatment of choice for colorectal liver metastases (CLM), with a 5-year survival rate ranging from 35% to 58%. Unfortunately, only about 20% of patients are eligible for resection. There are a number of options for extending resection to more advanced patients including systemic chemotherapy, portal vein embolization (PVE), two stage hepatectomy, ablation and hepatic artery infusion (HAI). There are few phase III trials comparing these treatment modalities, and choosing the right treatment is patient dependent. Treating hepatic metastases requires a multidisciplinary approach and knowledge of all treatment options as there continues to be advances in management of CLM. If a patient can undergo a treatment modality in order to increase their potential for future resection this should be the primary goal. If the patient is still deemed unresectable then treatments that lengthen disease-free and overall-survival should be pursued. These include chemotherapy, ablation, HAI, chemoembolization, radioembolization (RE) and stereotactic radiotherapy.

Boosted metric learning for 3D multi-modal deformable registration (2011)

Defining a suitable metric is one of the biggest challenges in deformable image fusion from different modalities. In this paper, we propose a novel approach for multi-modal metric learning in the deformable registration framework that consists of embedding data from both modalities into a common metric space whose metric is used to parametrize the similarity. Specifically, we use image representation in the Fourier/Gabor space which introduces invariance to the local pose parameters, and the Hamming metric as the target embedding space, which allows constructing the embedding using boosted learning algorithms. The resulting metric is incorporated into a discrete optimization framework. Very promising results demonstrate the potential of the proposed method.
Reduction of membrane fouling using a helical baffle for cross flow microfiltration (2004)

The introduction of turbulence promoters such as helical baffles were shown to enhance permeate flux during crossflow microfiltration. Helical inserts reduce hold-up in the feed channel; increase fluid velocity and wall shear rates and produce secondary flows or instabilities. The aim of this work was to investigate the influence of helical baffles on permeate flux during the microfiltration of titanium dioxide (TiO2) dispersions and bakers yeast solutions. Tubular, single channel ceramic membranes with nominal pore size of 0.2Âµm were used. Variations of the helical baffle geometries, which are the number of turns per baffle length, were investigated. It is found that the insertion of helical baffles increased the permeate flux. In some cases, the increase was more than 100%. The effect of number of turns per baffle length shows that the permeate flux increases with the number of turns but decreases when the number of turns is more than 4 turns per 50 mm baffle length. Thus, the optimum number of turn is 4 turns per 50mm.
Performance of DNS as location manager for wireless systems in IP networks (2005)

Domain name system (DNS) can be deployed in the network as a location manager (LM) for mobility management. The suitability of domain name system (DNS) as an LM can be measured by how successfully it can serve to locate a mobile host. In this paper, we developed an analytical model to measure the performance of DNS as LM for mobility management techniques with IP diversity support based on success rate which takes into account the radius of the subnet, the residence time of MH in that subnet, latency in the network and the overlapping distance of two neighboring subnets. Our analysis shows that for a reasonable overlapping distance, DNS can serve as an LM with very high success rate even under some high network latency.
Effects of Phenobarbital on Bilirubin Metabolism and Its Response to Phototherapy in the Jaundiced Gunn Rat (1985)

Jaundiced Gunn rats, treated with phenobarbital (60 mg per kg i.p. for 7 to 10 days) showed 25 and 36% decreases in mean plasma bilirubin levels in two experiments (p less than 0.01). Kinetic studies with tracer 14C-bilirubin revealed that there was no change in bilirubin turnover or total pool size due to phenobarbital, but a 49% increase in the hepatic pool and a 27% decrease in the cutaneous pool of bilirubin. The increase in the hepatic pool accounted for over 90% of the bilirubin lost from the plasma. Such pretreatment with phenobarbital did not alter the decline in plasma bilirubin or total bilirubin pool due to subsequent phototherapy. Phenobarbital followed by phototherapy produced a significantly greater reduction in plasma bilirubin levels than either treatment alone. These studies demonstrate that phenobarbital does decrease plasma bilirubin in Gunn rats primarily by shifting the pigment to the liver, and suggests that combined treatment with phenobarbital and phototherapy might be of value in patients with congenital hyperbilirubinemia due to glucuronyl transferase deficiency.
Modular hardware infrastructure for autonomous underwater vehicles (2005)

Autonomous underwater vehicles (AUVs) are taking on increasingly visible and valuable roles in oceanographic research institutions, the offshore industry, and the military (Podder et al., 2004 and Yongkuan, 2002). AUV research, especially at the university level, is hindered by the lack of flexible and affordable platforms suitable for a wide range of applications. This paper presents an electrical and mechanical infrastructure developed to improve the flexibility and modularity of research AUVs. External devices can be added or replaced with minimal vehicle modification. A power backplane offers built-in monitoring and switching for all electronic devices. A signal backplane allows new electronics to be quickly integrated into the existing system. Easily detachable segments make the entire system mechanically modular.
Solder joints inspection using a neural network and fuzzy rule-based classification method (2000)

In this paper, we described an approach in automation, the visual inspection of solder joint defects of surface mounted components on a printed circuit board, using a neural network with fuzzy rule-based classification method. Inherently, the solder joints have a curved, tiny, and specular reflective surface. This presents the difficulty in taking good images of the solder joints. Furthermore, the shapes of the solder joints tend to greatly vary with their soldering conditions, and are not identical with each other, even though some of the solder joints belong to a set of the same soldering quality. This problem makes it difficult to classify the solder joints according to their properties. To solve this intricate problem, a new classification method is here proposed which consists of two modules: one based upon an unsupervised neural network, and the other based upon a fuzzy set theory. The novel idea of this approach is that a fuzzy rule table reflecting the knowledge of criteria of a human inspector, is utilized in order to correct any possible misclassification made by the neural network module. The performance of the proposed approach was tested on numerous samples of printed circuit boards in commercially available computers, and then compared with that of a human inspector. Experimental results reveal that the proposed method is superior to the neural network classification method alone, in terms of its accuracy of classification.
Part 12: Cardiac Arrest in Special Situations (2010)

Part 12.1: Cardiac Arrest Associated With AsthmaAsthma is responsible for more than 2 million visits to the emergency department (ED) in the United States each year, with 1 in 4 patients requiring admission to a hospital. 1Annually there are 5,000 to 6,000 asthma-related deaths in the United States, many occurring in the prehospital setting. 2 Severe asthma accounts for approximately 2% to 20% of admissions to intensive care units, with up to one third of these patients requiring intubation and mechanical ventilation. 3This section focuses on the evaluation and treatment of patients with near-fatal asthma.Several consensus groups have developed excellent guidelines for the management of asthma that are available on the World Wide Web
Contact Technical Fundamentals of Feeder Clamps and their Influence on Design, Assembly and Maintenance (1985)

The permanent current-carrying capacity of feeder-clamps, particularly of feeder clamps for A1 conductors, is determined by a number of parameters, among which contact force, permanent elasticity, contact area, contact protection and safe assembly are the most important ones. The construction of typical clamps for bare as well as for insulated cabel conductors and overhead line conductors is carried out in the light of basic results. The differences between the assembly pressure necessary to produce the contact and the operating pressure necessary to maintain this contact are shown under the influence of heat cycles. The clamp elasticity of the residual contact force of the clamp resulting from the elasticity and its importance with regard to a maintenance-free life of the clamps are dealt with in particular. In a short summary the latest state of the IEC standards for testing feeder clamps is described and the focal points with regard to the measuring technique and its respective laboratory equipment are pointed out. The object of the paper is to make evident the practical utility of proven theories for planning, selection and use of feeder clamps, particularly of feeder clamps for aluminium conductors of all known construction types.
A Novel Virtual Force Approach for Node Deployment in Wireless Sensor Network (2012)

The effectiveness of wireless sensor networks (WSN) depends on the coverage and connectivity provided by node deployment, which is one of the key topics in WSN. In this paper, a modified virtual force-based node self-deployment algorithm for nodes with mobility is proposed. In the virtual force-based approach, all nodes are seen as points subject to repulsive and attractive force exerted among them, nodes can move according to the calculated force. In the proposed approach, Delaunay triangulation is formed with these nodes, adjacent relationship is defined if two nodes are connected in the Delaunay diagram. Force can only be exerted from those adjacent nodes within the communication range. Simulation results showed that the proposed approach has higher coverage rate and faster convergence time than traditional virtual force algorithm.

Single procedure for detection, confirmation, and quantification of benzodiazepines in serum by liquid chromatography with photodiode-array detection (1991)

We developed a reversed-phase chromatographic procedure for detecting benzodiazepines and other drugs in serum. A liquid-liquid extraction step with hexane/ethyl acetate isolates the drugs from serum; absolute recoveries are generally greater than 85%. Reconstituted extracts are chromatographed on a 4-microns (particle size) C18 column; 14 drugs and an internal standard (flunitrazepam) are separated in 8 min. Peak detection, purity checking, and identification are performed with a computerized photodiode-array detector. Run-to-run imprecision (CV) for many benzodiazepines is less than 3%. In a study of 126 specimens from Emergency Department patients, the procedure showed excellent agreement with a gas-chromatographic method involving either mass-spectrometric or flame-ionization detection. This single procedure provides rapid and accurate detection, quantification, and confirmation of benzodiazepines in serum.
Implementing Syndromic Surveillance: A Practical Guide Informed by the Early Experience (2003)

Syndromic surveillance refers to methods relying on detection of individual and population health indicators that are discernible before confirmed diagnoses are made. In particular, prior to the laboratory confirmation of an infectious disease, ill persons may exhibit behavioral patterns, symptoms, signs, or laboratory findings that can be tracked through a variety of data sources. Syndromic surveillance systems are being developed locally, regionally, and nationally. The efforts have been largely directed at facilitating the early detection of a covert bioterrorist attack, but the technology may also be useful for general public health, clinical medicine, quality improvement, patient safety, and research. This report, authored by developers and methodologists involved in the design and deployment of the first wave of syndromic surveillance systems, is intended to serve as a guide for informaticians, public health managers, and practitioners who are currently planning deployment of such systems in their regions.
Total chemical synthesis of a functional interacting protein pair: The protooncogene H-Ras and the Ras-binding domain of its effector c-Raf1 (2003)

Generation of biological function by chemical methods is potentially of great importance for the understanding and targeting of physiological processes. Chemical synthesis of proteins offers the ability to alter the properties of target protein molecules in a tailor-made fashion. In the present work it is demonstrated that this methodology can be expanded to the elucidation of protein-protein interactions as exemplified by the complete chemical synthesis of the protooncogene product H-Ras as well as of the Ras-binding domain (RBD) of its effector c-Raf1. The 166-aa polypeptide chain of H-Ras was synthesized by native chemical ligation of three unprotected peptide segments. Similarly, the 81-aa RBD was prepared by ligation of two peptide segments. Both RBD and Ras displayed functional and spectroscopic properties indistinguishable from their recombinant forms as judged by CD spectroscopy and from transient kinetic measurements of the Ras-RBD interaction as well as from nucleotide replacement reactions in Ras. An unnatural amino acid bearing a nitrobenzofurazan side chain was introduced into position 91 of the RBD, providing unique fluorescence properties. The association transient of nitrobenzofurazan labeled with Ras.guanosine 5'-beta,gamma-imidotriphosphate showed a slow phase that had not been detected in earlier work by using other signals.
Membrane expression of platelet calpain (1990)

Platelet calpain has many platelet substrates, including external membrane proteins. We thus investigated whether platelet calpain II was associated with platelet membranes in unstimulated and thrombin- activated platelets. A monospecific, goat polyclonal antibody was reared to purified platelet calpain II. Sixteen whole platelet lysates were found to contain 4.5 +/- 0.7 micrograms calpain antigen II per 10(8) platelets (mean +/- SEM) as determined by a competitive enzyme- linked immunosorbent assay. Using the dipeptide fluorogenic substrate, Suc-Leu-Tyr-MCA, 17 human platelet lysates contained 3.6 +/- 0.4 micrograms calpain activity per 10(8) platelets. Platelet calpain II was associated with the Triton X-100 insoluble platelet cytoskeletons from both unstimulated and thrombin-activated platelets. When compared with the total cell content of platelet calpain II, calpain antigen (10% to 13%) and calpain activity (24% to 28%) was associated with platelet cytoskeletons in unstimulated and thrombin-activated platelets, respectively. On immunoblot, the heavy chain (80 Kd) of calpain II was detected in platelet cytoskeletons. Subcellular fractionation studies on both unstimulated and thrombin-activated platelets, revealed that half of the total platelet calpain II antigen was associated with cytosol, and the other half was associated with the membrane fraction. Platelet calpain II was not seen on the surface of unstimulated, paraformaldehyde fixed platelets by immunofluorescence. However, on thrombin-activated platelets, rim immunofluorescence was seen, indicating that activated platelets externalize their calpain. This observation was confirmed by the finding that about 2,000 molecules per platelet of an 125I-anti-calpain II Fab' specifically bound to thrombin-activated but not unstimulated platelets. Both dibucaine (1 mmol/L) and platelet activating factor (1.86 mumol/L) in the absence of external Ca++, but not collagen (5 micrograms/mL) or ionophore A23187 (2.5 mumol/L) in the absence of external Ca++, were also able to externalize platelet calpain II antigen, as indicated by a similar level of specific 125I-anti-calpain II Fab'-platelet binding. These combined studies indicate that platelet calpain II is a major protein, comprising 2% of total platelet protein, a substantial portion of which is membrane-associated. When platelets are activated by thrombin and platelet activating factor, calpain II antigen also becomes present on the external platelet surface.
Miniature electron-optical columns (1991)

Miniaturized electron-optical systems based on a field emission microsource and a microlens for probe forming have been studied. The performance of systems with dimensions (length and diameter) in the submillimeter to millimeter range can exceed that of a conventional system over a wide range of potentials (100 V to 10 kV) and working distances (up to 10 mm). Electron-optical studies show that not only can a significant reduction in size be achieved but the performance in terms of resolution and especially beam current can also be greatly improved. A key component of the miniaturized system is the field emission microsource which provides an improvement of two to three orders of magnitude in effective brightness over the conventional field emission source. Among the options, the STM aligned field emission (SAFE) microsource appears most promising and a selective scaling approach has been developed to allow this source to operate over a wide range of potentials. Preliminary experimental studies of the microsource have been conducted.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High-Speed Monolithic Multipliers for Real-Time Digital Signal Processing (1978)
