A resonant pulse gate drive for high frequency applications (2003)

The analysis and implementation of a resonant pulse gate drive are discussed. The resonant gate drive is based on a simple charge pulse circuit which has conduction and logic losses. The pulse charging and discharging instances are controlled by the user, and hence this circuit is applicable to pulse width modulation (PWM) schemes as well as resonant converters. Theoretical analysis of the circuit shows its operation. Detailed equations are presented which describe the inherent losses of the circuit. Experimental results are shown to verify the operation and loss mechanisms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
110 km 256-QAM digital microwave over fiber link (2003)

A 110 km digital microwave fiber-optic link has been designed and demonstrated with 256 QAM at 20 GHz. The design approach, involving the management of loss, dispersion, and Brillouin threshold throughout the link is discussed.
Construction and control of massive hydraulic miniature-actuator-sensor array (2006)

Massive actuator arrays have found applications in robotics, pharmaceutics, aerospace, etc. Compared with either electrically or pneumatically powered actuator arrays, a hydraulic array has the advantages of higher force density (i.e. force / actuation volume), better controllability, and simpler remote control accessibility. This paper presents approaches to construct and control a massive hydraulic miniature actuator array. The massive hydraulic actuator array was originally constructed for project “Digital Clay” (a novel hydraulic actuated human machine interface device) as a tangible human and machine interaction media. A pin-rod planar actuator array is investigated in this work. In this paper, designs of the practical kinematical structure are discussed, proposed control methods for the actuator array are introduced and experiment results are presented.

GaN HEMT Based High Power and High Efficiency Doherty Amplifiers with Digital Pre-Distortion Correction for WiBro Applications (2011)

This paper presents high power and high efficiency Doherty amplifiers for 2.345 GHz wireless broadband (WiBro) applications that use a Nitronex 125-W (<TEX>$P_{3dB}$</TEX>) GaN high electron mobility transistor (HEMT). Two- and three-way Doherty amplifiers and a saturated Doherty amplifier using Class-F circuitry are implemented. The measured result for a center frequency of 2.345 GHz shows that the two-way Doherty amplifier attains a high <TEX>$P_{3dB}$</TEX> of 51.5 dBm, a gain of 12.5 dB, and a power-added efficiency (PAE) improvement of about 16 % compared to a single class AB amplifier at 6-dB back-off power region from <TEX>$P_{3dB}$</TEX>. For a WiBro OFDMA signal, the Doherty amplifier provides an adjacent channel leakage ratio (ACLR) at 4.77 MHz offset that is -33 dBc at an output power of 42 dBm, which is a 9.5 dB back-off power region from <TEX>$P_{3dB}$</TEX>. By employing a digital pre-distortion (DPD) technique, the ACLR of the Doherty amplifier is improved from -33 dBc to -48 dBc. The measured result for the same frequency shows that the three-way Doherty amplifier, which has a <TEX>$P_{3dB}$</TEX> of 53.16 dBm and a gain of 10.3 dB, and the saturated Doherty amplifier, which has a <TEX>$P_{3dB}$</TEX> of 51.1 dBm and a gain of 10.3 dB, provide a PAE improvement of 11 % at the 9-dB back-off power region and 7.5 % at the 6-dB back-off region, respectively, compared to the two-way Doherty amplifier.
The Illustrated Wavelet Transform Handbook: Introductory Theory and Applications in Science, Engineering, Medicine and Finance, Second Edition (2016)

This second edition of The Illustrated Wavelet Transform Handbook: Introductory Theory and Applications in Science, Engineering, Medicine and Finance has been fully updated and revised to reflect recent developments in the theory and practical applications of wavelet transform methods.
The book is designed specifically for the applied reader in science, engineering, medicine and finance. Newcomers to the subject will find an accessible and clear account of the theory of continuous and discrete wavelet transforms, while readers already acquainted with wavelets can use the book to broaden their perspective. 
One of the many strengths of the book is its use of several hundred illustrations, some in colour, to convey key concepts and their varied practical uses. Chapters exploring these practical applications highlight both the similarities and differences in wavelet transform methods across different disciplines and also provide a comprehensive list of over 1000 references that will serve as a valuable resource for further study.
Paul Addison is a Technical Fellow with Medtronic, a global medical technology company. Previously, he was co-founder and CEO of start-up company, CardioDigital Ltd (and later co-founded its US subsidiary, CardioDigital Inc) - a company concerned with the development of novel wavelet-based methods for biosignal analysis. He has a master’s degree in engineering and a PhD in fluid mechanics, both from the University of Glasgow, Scotland (founded 1451). His former academic life as a tenured professor of fluids engineering included the output of a large number of technical papers, covering many aspects of engineering and bioengineering, and two textbooks: Fractals and Chaos: An Illustrated Course and the first edition of The Illustrated Wavelet Transform Handbook. At the time of publication, the author has over 100 issued US patents concerning a wide range of medical device technologies, many of these concerning the wavelet transform analysis of biosignals. He is both a Chartered Engineer and Chartered Physicist.
Survival probability in ataxia telangiectasia (2005)

Ataxia telangiectasia is a rare, multiorgan neurodegenerative disorder with enhanced vulnerability to cancer and infection. Median survival in two large cohorts of patients with this disease, one prospective and one retrospective, is 25 and 19 years, with a wide range. Life expectancy does not correlate well with severity of neurological impairment.

T-cell receptor analysis by flow cytometry (2001)

I read with interest the article by van den Beemd et al. (1). The authors provided interesting data pertaining to the use of T-cell receptor (TCR) beta chains in healthy individuals. We published a similar study of normal individuals using monoclonal antibodies (2) and the data are comparable. Both studies illustrated the varied manner in which these data may be presented. We examined VB expression as a percentage of cell type and as absolute numbers of cells expressing various TCR VB chains. van den Beemd et al. presented data as a percentage of each subset divided by the percentage of cells that were alpha-beta positive. Each approach has particular advantages and disadvantages. The complementary data presented by the two studies expand our knowledge of TCR VB usage in normal individuals. We studied variations in TCR VB usage by individual donors over time, whereas van den Beemd et al. presented data related to TCR VB usage in different age groups. Both studies pointed out that defining the TCR VB repertoire in normal individuals is crucial to our understanding of aberrations in disease processes. The assessment of T-cell neoplasms may benefit from these studies (3, 4). Additionally, a myriad of other diseases, including HIV (5), may display alterations in TCR VB that are useful in diagnosis or monitoring. In conclusion, the study of TCR variable regions by flow cytometry has the potential to yield important clinical information. Continuing studies on normal individuals, such as the one by van den Beemd et al., should enhance the foundation for the potential application of flow cytometric analysis of TCR VB in the clinical laboratory.
Polynomial Threshold Elements? (2005)

It is a well known fact that the XOR function is not a linear threshold function.This is one of the reasons for the limited performance of neural networks models in which every node is a Linear Threshold (LT) element.A common solution to this problem is to consider generalized networks in which every node is performing a polynomial threshold function.A polynomial threshold (PT) element computes the sign of a polynomial (instead of a linear form in an LT element) with the restriction that the number of terms in the polynomial is "small."In order to evaluate the idea of generalized networks I will address the following fundamental question: what is the power of a PT element with respect to LT elements?The answer is that we do not gain much by using Prs instead of Lrs.A "small" two-layer network of Lrs can compute strictly more than a single PT element.In order to answer this question I have developed a novel technique that is based on Harmonic Analysis and derived lower bounds on the number of terms in such a representation.I will discuss this technique and use it to exhibit a Boolean function that can be qomputed by a "small" two-layer network of Lrs but can not be computed by a single PT element. 8-3
Emerging Roles of Anacardic Acid and Its Derivatives: A Pharmacological Overview (2011)

Anacardic acid (AA) is a bioactive phytochemical found in nutshell of Anacardium occidentale. Chemically, it is a mixture of several closely related organic compounds, each consisting of salicylic acid substituted with an alkyl chain. The traditional Ayurveda depicts nutshell oil as a medicinal remedy for alexeritic, amebicidal, gingivitis, malaria and syphilitic ulcers. However, the enduring research and emerging evidence suggests that AA could be a potent target molecule with bactericide, fungicide, insecticide, anti-termite and molluscicide properties and as a therapeutic agent in the treatment of the most serious pathophysiological disorders like cancer, oxidative damage, inflammation and obesity. Furthermore, AA was found to be a common inhibitor of several clinically targeted enzymes such as NFκB kinase, histone acetyltransferase (HATs), lipoxygenase (LOX-1), xanthine oxidase, tyrosinase and ureases. In view of this, we have made an effort to summarize the ongoing research on the therapeutical role of AA and its derivatives. The current MiniReview sheds light on the pharmacological applications, toxicity and allergic responses associated with AA and its derivatives. Although the available records are promising, much more detailed investigations into the therapeutical properties, particularly the anti-cancer and anti-inflammatory activities, are urgently needed. We hope the present MiniReview will attract and encourage further research on elucidating and appreciating the possible curative properties of AA and its derivatives in the management of multifactorial diseases.
The Hidden Costs of Divorce (1997)

Senator Lodge agrees that the Russian treaty cannot continue unless Russia abides by the terms. Arbitration could strengthen the American position but this would only be an interpretation and the Russians would not change their position. Lodge met with a delegation of Jewish Americans who were reasonable and appreciated Theodore Roosevelt's efforts. They simply believed that arbitration could never be successful. The campaign in Massachusetts appears promising and Lodge is relieved to hear of Edith Kermit Carow Roosevelt's condition.
Metal pad roll instability in liquid metal batteries (2017)

The increasing deployment of renewable energies requires three fundamental\nchanges to the electric grid: more transmission lines, a flexibilisation of the\ndemand and grid scale energy storage. Liquid metal batteries (LMBs) are\nconsidered these days as a promising means of stationary energy storage. Built\nas a stable density stratification of two liquid metals separated by a liquid\nsalt, LMBs have three main advantages: a low price, a long life-time and\nextremely high current densities. In order to be cheap, LMBs have to be built\nlarge. However, battery currents in the order of kilo-amperes may lead to\nmagnetohydrodynamic (MHD) instabilities, which - in the worst case - may\nshort-circuit the thin electrolyte layer. The metal pad roll instability, as\nknown from aluminium reduction cells, is considered as one of the most\ndangerous phenomena for LMBs. We develop a numerical model, combining fluid-\nand electrodynamics with the volume-of-fluid method, to simulate this\ninstability in cylindrical LMBs. We explain the instability mechanism similar\nto that in aluminium reduction cells and give some first results, including\ngrowth rates and oscillation periods of the instability.\n
Immunoadjuvant activities of cell walls, their water-soluble fractions and peptidoglycan subunits, prepared from various gram-positive bacteria, and of synthetic n-acetylmuramyl peptides. (1975)

1. The cell walls from some 20 species of gram-positive bacteria, with only few exceptions, were found to be definitely adjuvant-active in both stimulation of increased serum antibody levels and induction of delayed-type hypersensitivity to ovalbumin when administered to guinea pigs in the form of a water-in-oil emulsion. 2. By the use of various cell wall lytic enzymes, the immunoadjuvant principles were solubilized with the full retention of adjuvant activities observed with the cell walls of S. aureus, Str. pyogenes, Str. mutans, L. plantarum, C. diphtheriae, Myc. smegmatis and A. viscosus. N-acetylmuramyl peptide monomers (either L-Lys or meso-Dap type) were shown to be the unit chemical structure responsible for the manifestation of adjuvant activities to stimulate both antibody-mediated and cell-mediated immune responses. 3. Several N-Acetylmuramyl peptides were prepared by condensation of benzyl N-acetyl-4,6-O-benzylidene-alpha-muramide with each peptide benzyl ester by means of dicyclohexylcarbodiimide-N-hydroxysuccinimide method and removal of the protecting groups by hydrogenolysis. N-acetylmuramyl-L-alanyl-D-isoglutamine was identified as the minimum structural entity essential for the immunoadjuvant activities characteristic of bacterial cell walls. Neither synthetic N-acetylmuramyl-L-alanine nor L-alanyl-D-isoglutaminyl-L-lysyl-D-alanin was found to be active.
On the performance of ultra-wide-band signals in Gaussian noise and dense multipath (2001)

An ultra-wide-band (UWB) signal is characterized by a radiated spectrum with a very wide bandwidth around a relatively low center frequency. In this paper, we study the reduced fading margin property of UWB signals. To evaluate the fading margin, we compare the performance of UWB signals in an environment with only additive white Gaussian noise (AWGN) versus the performance of UWB signals in a dense multipath environment with AWGN. The assumption here is that the presence of multipath causes a small increase in the signal-to-noise ratio required to achieve reasonable levels of bit error rate. A numerical example confirms this assumption, more specifically, the example shows that to achieve a bit error rate equal to 10/sup -5/, we require about 13.5 dB in the AWGN case and about 15 dB in the multipath case, resulting in a fading margin of just 1.5 dB. This small fading margin can be understood by the ability of the UWB signal to resolve the dense multipath.

<i>Mycobacterium avium</i> Invades the Intestinal Mucosa Primarily by Interacting with Enterocytes (2001)

ABSTRACT Previous studies have demonstrated that Mycobacterium avium can invade intestinal epithelial cells both in vitro and in vivo. When given to mice orally, M. avium preferentially interacts with the intestinal mucosa at the terminal ileum. We evaluated the mechanism(s) of M. avium binding and invasion of the intestinal mucosa using three different systems: (i) electron microscopy following administration of M. avium into an intestinal loop in mice, (ii) quantitative comparison of the bacterial load in Peyer's patch areas of the terminal ileum versus areas that do not contain Peyer's patches, and (iii) investigation of the ability of M. avium to cause disseminated infection following oral administration using B-cell-deficient mice, lacking Peyer's patches, in comparison with C57BL/6 black mice. By all approaches, M. avium was found to invade the intestinal mucosa by interacting primarily with enterocytes and not with M cells.
Age- and stage-specific regulation patterns in the hematopoietic stem cell hierarchy (2001)

The molecular mechanisms that regulate self-renewal and differentiation of very primitive hematopoietic stem and progenitor cells in vivo are still poorly understood. Despite the clinical relevance, even less is known about the mechanisms that regulate these cells in old animals. In a forward genetic approach, using quantitative trait linkage analysis in the mouse BXD recombinant inbred set, this study identified loci that regulate the genetic variation in the size of primitive hematopoietic cell compartments of young and old C57BL6 and DBA/2 animals. Linked loci were confirmed through the generation and analysis of congenic animals. In addition, a comparative linkage analysis revealed that the number of primitive hematopoietic cells and hematopoietic stem cells are regulated in a stage-specific and an age-specific manner.
Cost-effectiveness of the introduction of specialized oral care with laser therapy in hematopoietic stem cell transplantation (2013)

Oral mucositis (OM) is one of the side effects of hematopoietic stem cell transplantation (HSCT), resulting in major morbidity. The aim of this study was to determine the cost-effectiveness of the introduction of a specialized oral care program including laser therapy in the care of patients receiving HSCT with regard to morbidity associated with OM. Clinical information was gathered on 167 patients undergoing HSCT and divided according to the presence (n = 91) or absence (n = 76) of laser therapy and oral care. Cost analysis included daily hospital fees, parenteral nutrition (PN) and prescription of opioids. It was observed that the group without laser therapy (group II) showed a higher frequency of severe degrees of OM (relative risk = 16.8, 95% confidence interval -5.8 to 48.9, p < 0.001), with a significant association between this severity and the use of PN (p = 0.001), prescription of opioids (p < 0.001), pain in the oral cavity (p = 0.003) and fever > 37.8°C (p = 0.005). Hospitalization costs in this group were up to 30% higher. The introduction of oral care by a multidisciplinary staff including laser therapy helps reduce morbidity resulting from OM and, consequently, helps minimize hospitalization costs associated with HSCT, even considering therapy costs.

Dendritic cells modulate platelet activity in IVIg-mediated amelioration of ITP in mice (2010)

Intravenous immunoglobulin (IVIg) is an effective treatment against immune thrombocytopenia (ITP). Previous studies suggested that IVIg exerts this ameliorative role through 2 different leukocyte subsets. Dendritic cells (DCs) modulate the immunosuppression in an adoptive cell transfer model, and phagocytes up-regulate their inhibitory IgG Fc receptors (FcγR)IIB expression and thereby ameliorate the inflammatory response and platelet clearance. However, whether or not regulatory mechanisms exist among DCs, phagocytes, and platelets is still largely unknown. In this study we present findings that IVIg-primed splenic CD11c(+) DCs (IVIg-DCs) primarily mediate their anti-inflammatory effects at the level of the platelet rather than the phagocyte. IVIg-DCs did not ameliorate ITP in Fcgr2b(-/-), Fcgr3(-/-), nor P-Selp(-/-) mice, implicating the potential involvement of these pathways in IVIg action. As platelets are a component of DC regulatory circuits, these findings may suggest an alternative perspective for the use of IVIg treatment.
Generating revocable fingerprint template using minutiae pair representation (2010)

With the growing concern for secure and private information protection, several issues pertaining to the traditional biometric authentication system such as the reissuance of biometric template and template security have been raised. To resolve these limitations, many new concepts of revocable biometrics have been introduced. However, the design of a template protection scheme that fulfils all the security and privacy criteria, namely revocability, non-invertibility, and anonymity, is still a challenging task. In this paper, we present a secure fingerprint template protection scheme by using minutiae pair representation that extends the concept of revocable biometrics. The proposed method integrates template with its discriminative helper data to achieve acceptable equal error rate (EER) of near 0%. Apart from performance, the security and privacy issues such as revocability and non-invertibility are also discussed.
