Reverse-field reciprocity for conducting specimens in magnetic fields (1987)

A new static-electromagnetic reciprocity principle is presented, extending ordinary resistive reciprocity to the case of nonzero magnetic fields by requiring the magnetic field to be reversed when the reciprocal measurement is made. The principle is supported by measurements on various types of specimens, including those which exhibit the quantum-Hall effect. A derivation using elementary electromagnetic theory shows that the principle will hold provided only that the specimen is electrically linear (Ohmic), and that the Onsager form for the conductivity tensor applies throughout. The principle has important implications for electrical measurements on semiconductors in applied-magnetic fields.
Induced Magnetic Ordering by Proton Irradiation in Graphite (2003)

We provide evidence that proton irradiation of energy 2.25 MeV on highly oriented pyrolytic graphite samples triggers ferro- or ferrimagnetism. Measurements performed with a superconducting quantum interferometer device and magnetic force microscopy reveal that the magnetic ordering is stable at room temperature.

Impact of Photon Lifetime on High-Speed VCSEL Performance (2011)

We investigate the impact of reduced photon lifetime on the static and dynamic performance of high-speed, oxide-confined 850-nm vertical-cavity surface-emitting lasers (VCSELs). The photon lifetime is reduced by a shallow-surface etch that lowers the reflectivity of the top mirror. From an analysis of the dependence of slope efficiency on mirror loss (etch depth) and temperature, we deduce values for the internal quantum efficiency and the internal optical loss and their dependencies on temperature. From an analysis of the dependence of the small-signal-modulation response on photon lifetime (etch depth) and temperature, we deduce values for differential gain and gain compression, and their dependencies on photon lifetime and temperature. We find a tradeoff between high resonance frequency and low damping for speed enhancement, leading to an optimum photon lifetime close to 3 ps for this particular VCSEL design that enables a modulation bandwidth of 23 GHz and error-free transmission at 40 Gb/s.
Characterizing and modeling the behavior of context switch misses (2008)

One of the essential features in modern computer systems is context switching, which allows multiple threads of execution to time-share a limited number of processors. While very useful, context switching can introduce high performance overheads, with one of the primary reasons being the cache perturbation effect. Between the time a thread is switched out and when it resumes execution, parts of its working set in the cache may be perturbed by other interfering threads, leading to (context switch) cache misses to recover from the perturbation.
A Topological Study of Textile Structures. Part I: An Introduction to Topological Methods (2009)

This paper proposes a new systematic approach for the description and classification of textile structures based on topological principles. It is shown that textile structures can be considered as a specific case of knots or links and can be represented by diagrams on a torus. This enables modern methods of knot theory to be applied to the study of the topology of textiles. The basics of knot theory are briefly introduced. Some specific matters relating to the application of these methods to textiles are discussed, including enumeration of textile structures and topological invariants of doubly-periodic structures.
Serratia odorifera a Midgut Inhabitant of Aedes aegypti Mosquito Enhances Its Susceptibility to Dengue-2 Virus (2012)

Mosquito midgut plays a crucial role in its vector susceptibility and pathogen interaction. Identification of the sustainable microflora of the midgut environment can therefore help in evaluating its contribution in mosquito-pathogen interaction and in turn vector competence. To understand the bacterial diversity in the midgut of Aedes aegypti mosquitoes, we conducted a screening study of the gut microbes of these mosquitoes which were either collected from fields or reared in the laboratory "culture-dependent" approach. This work demonstrated that the microbial flora of larvae and adult Ae. aegypti midgut is complex and is dominated by gram negative proteobacteria. Serratia odorifera was found to be stably associated in the midguts of field collected and laboratory reared larvae and adult females. The potential influence of this sustainable gut microbe on DENV-2 susceptibility of this vector was evaluated by co-feeding S. odorifera with DENV-2 to adult Ae. aegypti females (free of gut flora). The observations revealed that the viral susceptibility of these Aedes females enhanced significantly as compared to solely dengue-2 fed and another gut inhabitant, Microbacterium oxydans co-fed females. Based on the results of this study we proposed that the enhancement in the DENV-2 susceptibility of Ae. aegypti females was due to blocking of prohibitin molecule present on the midgut surface of these females by the polypeptide of gut inhabitant S. odorifera.
Utilization of Corn Co-Products in the Beef Industry: Feeding of Corn Milling Co-Products to Beef Cattle (2007)

Corn milling co-products are expected to increase dramatically in supply as the ethanol industry expands. Distillers grains, corn gluten feed, or a combination of both co-products offer many feeding options when included in pasture and feedlot diets. These co-product feeds may effectively improve cattle performance and operation profitability. When these co-products are fed in feedlot diets, adjustments to grain processing method and roughage level may improve cattle performance. Innovative storage methods for wet co-products and the use of dried co-products offer small operations flexibility when utilizing co-products. As new co-products are developed by ethanol plants, they should be evaluated with performance data to determine their product-specific feeding values.
A New Technique – Semicontinuous Rapid Flow, High Volume Exchange – For Effective Peritoneal Dialysis in Shorter Periods (1982)

During the period of study, 85 dialysis clearance periods were studied in a total of 42 dialyses. Peritoneal clearance of urea and creatinine were observed at varying flow rates of dialysing fluid ranging from 2 litres/hour to 8.5 litres/hour. Flow rates were adjusted to various speeds with indigineously designed diaphragm pump. The diaphragm pump is cheap and simple and has an electronically controlled timer. A linear correlation was observed between dialysate flow rate and peritoneal clearances. With this semicontinuous rapid flow, high volume exchange peritoneal dialysis technique described in this study, correction of serum potassium disturbance is found to be excellent even in shorter periods.
Synthesis of Nonhydrolyzable Analogues of Thiazole-4-carboxamide and Benzamide Adenine Dinucleotide Containing Fluorine Atom at the C2‘ of Adenine Nucleoside: Induction of K562 Differentiation and Inosine Monophosphate Dehydrogenase Inhibitory Activity (1997)

Thiazole-4-carboxamide adenine dinucleotide (TAD) analogue 7 containing a fluorine atom at the C2' arabino configuration of the adenine nucleoside moiety was found to be a potent inducer of differentiation of K562 erythroid leukemia cells. This finding prompted us to synthesize its hydrolysis-resistant methylenebis(phosphonate) and difluoromethylenebis(phosphonate) analogues 8 and 9, respectively. Since both TAD and benzamide adenine dinucleotide (BAD) are potent inhibitors of inosine monophosphate dehydrogenase (IMPDH), the corresponding fluorine-substituted methylenebis(phosphonate) analogue 12 of BAD was also synthesized. Thus, 9-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)adenine (13) was converted in five steps into the corresponding methylenebis(phosphonate) analogue 18. Dehydration of 18 with DCC led to the formation of the bicyclic trisanhydride intermediate 19a, which upon reaction with 2',3'-O-isopropylidenetiazofurin (20) or -benzamide riboside (21) followed by hydrolysis and deprotection afforded the desired methylene-bridged dinucleotides 8 and 12, respectively. The similar displacement of the 5'-mesyl function of 2',3'-O-isopropylidene-5'-O-mesyltiazofurin (24) with the difluoromethylenebis(phosphonic acid) derivative gave the phosphonate 25 which was coupled with 13 to afford 26. The desired difluoromethylenebis(phosphonate) analogue 9 was obtained by deprotection with Dowex 50/H+. This compound as well as beta-CF2-TAD (4) showed improved differentiation-inducing activity over beta-CH2-TAD (3), whereas analogues containing the -CH2-linkage (8 and 12) were inactive.
Near-field: A finite-difference time-dependent method for simulation of electrodynamics on small scales (2011)

We develop near-field (NF), a very efficient finite-difference time-dependent (FDTD) approach for simulating electromagnetic systems in the near-field regime. NF is essentially a time-dependent version of the quasistatic frequency-dependent Poisson algorithm. We assume that the electric field is longitudinal, and hence propagates only a set of time-dependent polarizations and currents. For near-field scales, the time step (dt) is much larger than in the usual Maxwell FDTD approach, as it is not related to the velocity of light; rather, it is determined by the rate of damping and plasma oscillations in the material, so dt = 2.5 a.u. was well converged in our simulations. The propagation in time is done via a leapfrog algorithm much like Yee's method, and only a single spatial convolution is needed per time step. In conjunction, we also develop a new and very accurate 8 and 9 Drude-oscillators fit to the permittivity of gold and silver, desired here because we use a large time step. We show that NF agrees with Mie-theory in the limit of small spheres and that it also accurately describes the evolution of the spectral shape as a function of the separation between two gold or silver spheres. The NF algorithm is especially efficient for systems with small scale dynamics and makes it very simple to introduce additional effects such as embedding.

New cosine similarity scorings to implement gender-independent speaker verification (2013)

This paper is a natural extension of our previous work on gender-independent speaker verification systems [1]. In a previous paper, we presented a solution to avoid using gender information in the Probabilistic Linear Discriminant Analysis (PLDA) without any loss of accuracy compared with a genderdependent base-line implementation. In this work, we propose two solutions to make a speaker verification system based on Cosine similarity independent of speaker gender. Our choice of the Cosine similarity is motivated by the fact that it is proved itself as a second state-of-the art - in parallel with PLDA- of i-vector based speaker verification systems. As measured by Equal Error Rate and min DCF’s, performance results on the extended telephone list coreext-coreext condition of SRE2010 1 show no performance decrease in
Multifunctional balloon catheters of the future (2011)

Cardiovascular medicine has benefited, both diagnostically and therapeutically, from dramatic advances that have occurred in catheter-based techniques. Today, as standardof-care, we routinely measure pressure and flow in vessels, cardiac chambers and across valves, image the vasculature at high resolution, and therapeutically balloon-dilate and stent arteries and other cardiovascular structures. Despite these capabilities, new catheter-based techniques continue to emerge. Interventional cardiologists are universally excited by the anticipated regulatory approval of percutaneous valve systems and other structural heart technologies. Can we go further? The answer is yes, as a result of significant advances that have occurred in material science and micro/ nanoelectronics. Recently, a class of novel materials has been developed: stretchable polymer-electronic composites [1,2]. Utilizing these materials, a new class of catheters has been constructed, containing dense arrays of sensors and therapeutic modules [3,4]. In this article we highlight the present and future status of integrating stretchable electronics with cardiovascular catheter systems.
Studies of Acyl and Thioacyl Isocyanates. IX. The Cycloaddition Reactions of Benzoyl and Thiobenzoyl Isocyanates with Anils (1972)

Abstract Thiobenzoyl isocyanates react with benzylidenanilines, benzylidenalkylamines and dianils to yield the corresponding mono- and bis (4+2) cycloadducts. Benzoyl isocyanates do not react with benzylidenanilines, but they are easily added to benzylidenebenzylamine to give the (4+2) cycloadducts in good yields. Cycloaddition of these isocyanates to anils is dependent upon the basicity of the nitrogen atom of C=N bond. Neither benzoyl isocyanates nor thiobenzoyl isocyanates are added to the C=C bond of cinnamylidenanilines, but they react with the C=N bond to afford the (4+2) cycloadducts.
Polyimide and SU-8 microfluidic devices manufactured by heat-depolymerizable sacrificial material technique (2004)

The following paper describes a sacrificial layer method for the manufacturing of microfluidic devices in polyimide and SU-8. The technique uses heat-depolymerizable polycarbonates embedded in polyimide or SU-8 for the generation of microchannels and sealed cavities. The volatile decomposition products originating from thermolysis of the sacrificial material escape out of the embedding material by diffusion through the cover layer. The fabrication process was studied experimentally and theoretically with a focus on the decomposition of the sacrificial materials and their diffusion through the polyimide or SU-8 cover layer. It is demonstrated that the sacrificial material removal process is independent of the actual channel geometry and advances linearly with time unlike conventional sacrificial layer techniques. The fabrication method provides a versatile and fast technique for the manufacturing of microfluidic devices for applications in the field of microTAS and Lab-on-a-Chip.
Role of Inhaled Steroids in Vascular Airway Remodelling in Asthma and COPD (2012)

In chronic obstructive airway diseases, such as asthma and chronic obstructive pulmonary disease (COPD), changes in bronchial microvasculature are present in response to inflammatory stimuli. Vascular changes may significantly contribute to airway wall remodelling. Angiogenesis and vascular leakage are prevalent in asthma, while vasodilation and vascular leakage dominate in COPD. An endothelial dysfunction may be present both in asthma and in COPD. Vascular changes may occur simultaneously with the thickening of the airway wall and the narrowing of the bronchial lumen. Consequently, pharmacological control of bronchial vascular remodelling may be crucial for symptom control in asthma and COPD. In asthmatic airways, inhaled steroids can downregulate vascular remodelling by acting on proangiogenic factors. Additionally, studies on combination therapy with long-acting β2-agonists and inhaled steroids have provided evidence of a possible synergistic action on components of vascular remodelling in asthma. In COPD, there is less experimental evidence on the effect of inhaled steroids on airway microvascular changes. Importantly, vascular endothelial growth factor (VEGF), the most specific growth factor for vascular endothelium, is crucially involved in the pathophysiology of airway vascular remodelling, both in asthma and COPD. The inhibition of VEGF and its receptor may be useful in the treatment of the vascular changes in the airway wall.
Distribution kinetics of targeted cytotoxin in glioma by bolus or convection-enhanced delivery in a murine model (2004)

These studies provide confirmation of a previous hypothesis that CED of IL-13 cytotoxin is superior to bolus injections not only for the safety of the normal brain but also for maintaining drug levels for a prolonged period in infused brain tumors. These findings are highly relevant and important for the optimal clinical development of IL-13 cytotoxin or any other targeted antitumor agent for GBM therapy, in which multiple routes of delivery of an agent are being contemplated.
Synthesis and CAD of permanent magnet DC brushless motors (2010)

Synthesis and CAD of permanent magnet DC brushless motors The paper presents an algorithm and software for the optimal design of permanent magnet brushless DC motors. Such motors are powered by DC voltage sources via semiconductor switches connected to the motor phase belts. The software is adjusted to the design of motors with NdFeB high energy density magnets. An attention has been given to issues important in the design of the motors, i.e., permanent magnet selection, structure of magnetic circuit, and armature windings. Particularly, precision of calculation of the permanent magnet operating point, visualization of selection process of the winding belts, and magnetic circuit dimensioning have been investigated. The authors have been trying to make the equations more specific and accurate than those presented in the literature. The user software interface allows changes in the magnetic circuit dimensions, and in the winding parameters. It is possible to examine simultaneously the influence of these changes on the calculation results. The software operates both with standard and inverted (outer rotor) motor structure. To perform optimization, a non-deterministic method based on the evolution strategy ( μ + λ ) - ES has been used.

Sequence analysis and characterization of the Porphyromonas gingivalis prtC gene, which expresses a novel collagenase activity (1992)

In order to examine the potential role of bacterial collagenases in periodontal tissue destruction, we recently isolated a gene, prtC, from Porphyromonas gingivalis ATCC 53977, which expressed collagenase activity (N. Takahashi, T. Kato, and H. K. Kuramitsu, FEMS Microbiol. Lett. 84:135-138, 1991). The nucleotide sequence of the gene has been determined, and the deduced amino acid sequence corresponds to a basic protein of 37.8 kDa. In addition, Southern blot analysis indicated that the prtC gene is conserved among the three major serotypes of P. gingivalis. The enzyme has been purified to near homogeneity from Escherichia coli clone NTS1 following Mono Q anion exchange and sequential gel filtration chromatography. The molecular mass of the purified enzyme was estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to be ca. 35 kDa, and the active enzyme behaved as a dimer following gel filtration chromatography. The collagenase degraded soluble and reconstituted fibrillar type I collagen, heat-denatured type I collagen, and azocoll but not gelatin or the synthetic collagenase substrate 4-phenylazobenzyloxycarbonyl-Pro-Leu-Gly-Pro-D-Arg. Enzyme activity was enhanced by Ca2+ and inhibited by EDTA, sulfhydryl-blocking agents, and the salivary peptide histatin. Preliminary evidence for the existence of a second collagenase expressed by strain 53977 was also obtained.
LevelSync: A hierarchical time synchronization mechanism for wireless sensor networks (2014)

Time synchronization in wireless sensor networks is a critical requirement for distributed and collaborative processing among the nodes. This paper presents a coarse grained hierarchical time synchronization scheme `LevelSync' which synchronizes nodes in a sensor network with regards to their distance from the sink or master node. A hierarchical tree is dynamically constructed during the synchronization with master node acting as the root. The master node initiates and controls the synchronization phase and is responsible for normalizing the virtual time with the corresponding UTC. Each node is assigned a level and maintains a virtual clock which runs at a frequency different than that of its physical clock. Virtual clocks run at a fixed frequency calculated by the root or reference nodes hence are free from the drifts. LevelSync decreases the number of messages required for the synchronization and the resynchronization periods. We evaluate the performance and energy efficiency of the LevelSync through simulation and compare with existing time synchronization protocols. LevelSync is computationally light, energy efficient and achieves long lasting synchronizations.
Bruton's Tyrosine Kinase is involved in innate and adaptive immunity. (2005)

Btk is a cytoplasmic tyrosine kinase, which is mainly involved in B cell receptor signalling. Gene targeting experiments revealed that Btk is important for B cell development and function. However, Btk is not only expressed in B cells, but also in most other haematopoietic lineages except for T cells and plasma cells. Recently we found that Btk is involved in Toll-like receptor signalling. Toll-like receptors play an important role in innate immunity. They are highly expressed on mast cells, macrophages and dendritic cells, which are essential for the recognition and consequently for the elimination of microbial pathogens. Therefore Btk might play an important role for the function of immunocompetent cells of innate as well as adaptive immunity.
