Application of Nanomagnetic Particles in Hyperthermia Cancer Treatment (2006)

This research focuses on developing uniform particles with a Curie temperature that is similar to the therapeutic one for the purpose of cancer treatment. Such particles will self-regulate the temperature of the tumor during magnetic hyperthermia (MH), thus avoiding the use of temperature controls. MH is based on a defined transfer of power onto magnetic nanoparticles in an alternate magnetic field that is determined by the frequency, magnetic field’s strength, materials and the size of the particles, which result in localized generation of heat. This heat will either destroy the tumor cells directly or results in a synergic reinforcement of radiation efficacy, depending on the equilibrium temperature set in the tumor tissue. MH involves the local deposition of tumor cell specific magnetic nanoparticles and an external alternating current magnetic field applicator system. Nanoferrite particles can be easily applied interstitially for minimum invasive application. In this study more uniform nanoparticles have been manufactured and they were tested for their Curie temperature for self–regulated MH. Materials which have been investigated for such procedure are Gd-Zn ferrite, MnZnFe2O4 and La3/4Sr1/4MnO3 and many others. Finally, the concept of discrete magnetic heating is addressed.

Managing the complexity of communication: regulation of gap junctions by post-translational modification (2013)

Gap junctions are comprised of connexins that form cell-to-cell channels which couple neighboring cells to accommodate the exchange of information. The need for communication does, however, change over time and therefore must be tightly controlled. Although the regulation of connexin protein expression by transcription and translation is of great importance, the trafficking, channel activity and degradation are also under tight control. The function of connexins can be regulated by several post translational modifications, which affect numerous parameters; including number of channels, open probability, single channel conductance or selectivity. The most extensively investigated post translational modifications are phosphorylations, which have been documented in all mammalian connexins. Besides phosphorylations, some connexins are known to be ubiquitinated, SUMOylated, nitrosylated, hydroxylated, acetylated, methylated, and γ-carboxyglutamated. The aim of the present review is to summarize our current knowledge of post translational regulation of the connexin family of proteins.

Mechanochemical Strengthening of a Multi-mechanophore Benzocyclobutene Polymer (2015)

The mechanical stresses that materials experience during use can lead to aging and failure. Recent developments in covalent mechanochemistry have provided a mechanism by which those stresses can be channeled into constructive, rather than destructive, responses, including strengthening in materials. Here, the synthesis and mechanical response of a polymer containing multiple benzocyclobutene (BCB) mechanophores along its backbone are reported. When solutions of the BCB polymer were exposed to the normally destructive elongational flow forces generated by pulsed ultrasonication, the number of intermolecular bond-forming reactions was greater than the number of bond-breaking reactions, leading to a net increase in polymer molecular weight. The molecular weight increase could be turned into gelation by introducing a bismaleimide cross-linker that reacts with the <i>ortho</i>-quinodimethide intermediate generated by mechanically assisted ring opening of the BCB mechanophores and using polymer concentrations in excess of the critical overlap concentration. Unlike a previous mechanically induced gelation of a mechanophore-based polymer, the BCB cross-linking requires no ionic components and represents an attractive, second platform for stress-strengthening materials.
Bladder-cancer incidence in relation to vegetable and fruit consumption: A prospective study of atomic-bomb survivors (2000)

We examined the relation between consumption of 22 dietary items and subsequent bladder-cancer incidence in a cohort of atomic-bomb survivors in Japan. Subjects were 38,540 people (14,873 men and 23,667 women) who responded to a mail survey carried out between 1979 and 1981 and who had no known cancer diagnosed before the start of follow-up (1 January 1980 for men, 1 February 1981 for women). Consumption frequencies for 22 dietary items were ascertained with pre-coded answers. As of the end of 1993, there were 114 (83 men and 31 women) incident cases of bladder cancer among 450,326 person-years at risk. Statistical analysis was done using Poisson regression for grouped survival data Consumption of green-yellow vegetables and fruit were protectively associated with risk. Adjusted for gender, age, radiation exposure, smoking status, educational level, body-mass index and calendar time, the relative risk (RR) for those consuming green-yellow vegetables 2-4 times per week and almost everyday was 0.62 [95% confidence interval (CI) 0.39-0.98] and 0.54 (95% CI 0.30-0.94) respectively, as compared with those consuming once per week or less. The corresponding RR for fruit consumption was 0.50 (0.30-0.81) and 0.62 (0.39-0.99) respectively. Chicken consumption was unexpectedly associated with decreased risk, but additional adjustment for consumption did not change the relation of green-yellow vegetables or of fruit to risk. The consumption of the other dietary items, including meat and green tea, was not related to risk. The findings add to evidence that high consumption of vegetables and fruit are protective against bladder cancer.
De kosten en baten van bedrijfsbewegingsprogramma's (2004)

Dit artikel maakt de huidige stand van kennis op over de kosten en baten van bedrijfsbewegingsprogramma's. Een aantal bedrijven biedt reeds een of andere vorm van bewegingsstimulering aan. Veel andere bedrijven aarzelen echter nog om een bedrijfsbewegingsprogamma te starten. Inzicht in de kosten en baten van dergelijke programma's zou de twijfel wellicht kunnen wegnemen en werknemers kunnen aanzetten meer te gaan bewegen. De conclusie is dat het beschikbare onderzoek nog steeds methodologisch zwak is. Belangrijkste tekortkoming is het ontbreken van een gerandomiseerde gecontroleerde opzet, zodat vergelijking veelal plaatsvindt tussen deelnemers en niet-deelnemers aan het programma. Ook een standaardisatie voor de berekening van de kosten en baten ontbreekt als gevolg waarvan resultaten niet goed vergelijkbaar zijn. Desondanks lijkt op basis van de voor dit artikel geraadpleegde literatuur de conclusie gerechtvaardigd dat de baten van bedrijfsbewegingsprogramma's groter zijn dan de kosten.
Smooth motion vector resampling for standard compatible video post-processing (2005)

This paper presents a smooth motion vector resampling method that operates on a given motion vector field for video coding applications such as resolution change in transcoding or concealment of lost motion vectors. We formulate the motion resampling problem as an optimization problem, where the proposed algorithm obtains the optimal solution by minimizing a smoothness criteria imposed between adjacent motion vectors. The problem is formulated in the most general case, which enables us to explain some other resampling methods such as motion vector averaging, or linear interpolation as special cases. The simulation results show that the proposed algorithm can efficiently improve the visual quality of the video.
Reduction of DC bus capacitor ripple current with PAM/PWM converter (2003)

Electrolytic capacitors are used in nearly all adjustable speed drives (ASD) and they are one of the components most prone to failure. The main failure mechanisms include the loss of electrolyte through outgassing and chemical changes to the oxide layer. All the degradation mechanisms are exacerbated by ripple current heating. Since the equivalent series resistance (ESR) of electrolytic capacitors is a very strong function of frequency, it must be properly modeled to accurately calculate the power loss. In this paper, a method to reduce the ripple current in a constant Volts/Hertz (V/f) pulse amplitude modulation (PAM/PWM) converter driving an induction motor is investigated. The DC bus voltage amplitude is reduced in proportion to speed by a buck or current source rectifier (CSR) and the PWM modulation index is increased to achieve a reduced ripple current below base speed. It is shown that this mode of operation can lead to a significant reduction in capacitor power loss leading to increased capacitor lifetime or decreased capacitor size. The capacitor heating is analyzed using numerical and analytical techniques. Experimental results are provided to verify the analytical results.
Flow Visualisation in Co-rotating Twin Screw Extruders: Positron Emission Particle Tracking and Numerical Particle Trajectories (2011)

Abstract Co-rotating twin-screw extruders are widely used compounding machines. They are mainly configured based on extensive experience and iterative approaches to optimise output and composite quality. The visualisation technology developed in the EU-project PEPTFlow allows visualisation of composite flow in twin-screw extruders under realistic processing conditions by tracking radioactive tracer particles in the polymer melt, using a specially developed camera system. This new approach allows polymer flow to be studied in different screw elements and screw configurations under realistic compounding conditions at normal temperatures and melt pressures. The paper presents the latest developments in the camera systems as well as the different ways to use and interpret the results. Detailed analysis of residence times and residence time distributions for standard compound screw elements, like kneading discs, conveying elements and reverse elements are presented. In addition for a better understanding of the flow field inside twin-screw extruders, numerical particle tracking is done. The Stokes equation, using XFEM method, are solved and the numerical RTD's (residence time distribution) are compared for various screw designs.
DOA Estimation of Speech Signal Using Microphones Located at Vertices of Equilateral Triangle (2004)

In this paper, we propose a DOA (Direction Of Arrival) estimation method of speech signal using three microphones. The angular resolution of the method is almost uniform with respect to DOA. Our previous DOA estimation method using the frequency-domain array data for a pair of microphones achieves high precision estimation. However, its resolution degrades as the propagating direction being apart from the array broadside. In the method presented here, we utilize three microphones located at vertices of equilateral triangle and integrate the frequency-domain array data for three pairs of microphones. For the estimation scheme, the subspace analysis for the integrated frequency array data is proposed. Through both computer simulations and experiments in a real acoustical environment, we show the efficiency of the proposed method.
Detecting performance anomalies in global applications (2005)

Understanding real, large distributed systems can be as difficult and important as building them. Complex modern applications that span geographic and organizational boundaries confound performance analysis in challenging new ways. These systems clearly demand new analytic methods, but we are wary of approaches that suffer from the same problems as the systems themselves (e.g., complexity and opacity).

This paper shows how to obtain valuable insight into the performance of globally-distributed applications without abstruse techniques or detailed application knowledge: Simple queueing-theoretic observations together with standard optimization methods yield remarkably accurate performance models. The models can be used for performance anomaly detection, i.e., distinguishing performance faults from mere overload. This distinction can in turn suggest both performance debugging tools and remedial measures.

Extensive empirical results from three production systems serving real customers--two of which are globally distributed and span administrative domains-- demonstrate that our method yields accurate performance models of diverse applications. Our method furthermore flagged as anomalous an episode of a real performance bug in one of the three systems.
Optische Spektroskopie von einzelnen Dotierungsmolekülen in Festkörpern (1993)

Abstract Mit der optischen Spektroskopie von einzelnen Dotierungsmolekülen in Festkörpern steht nun erstmals eine wirklich lokale Sonde zum Studium von Wirt‐Gast‐Wechselwirkungen zur Verfügung. Aus konventionellen optisch hochauflösenden Experimenten mit vielen Molekülen erhält man nur die Ensemblemittelwerte der mikroskopischen Parameter. Experimente mit einzelnen Molekülen sind dagegen durch die selektive Empfindlichkeit des betreffenden Dotierungsmoleküls gegenüber seiner lokalen Umgebung und damit auch gegenüber externen Störungen ausgezeichnet. Derartige Experimente wurden jüngst möglich und machten eine Vielfalt neuer, faszinierender Phänomene dem Studium zugänglich. Dazu gehören spektrale Diffusion in Kristallen und Polymeren, optische Manipulation eines einzelnen Dotierungsmoleküls (spektrales Lochbrennen), Messungen des lokalen Feldes in der Umgebung des Moleküls und quantenoptische Experimente im Festkörper.
Implementation of interactive poster "SuiPo" (2007)

This paper explains an implementation of new media "SuiPo," or Suica Poster, which uses a combination of IC card ticket "Suica" and Internet accessible mobile phone. Customers can get e-mail information by touching their IC card ticket on the reader located near the poster. Two pilot tests are conducted before the service has begun. The first test revealed that many people preferred the interactive poster but the registration process was complicated. The second test was conducted after improving the registration process. The lessons learned through two pilot tests are that in addition to the easier registration process, the increased popularity of two dimensional barcode reader in mobile phone has lowered the barrier of registration process.
SAR Autofocus Using Wiener Deconvolution (2010)

This paper proposes a new approach to synthetic aperture radar (SAR) autofocus. The proposed metric-based autofocus algorithm is based on the Wiener deconvolution filter, which has the advantage of the phase error compensation as well as noise suppression. The sharpness metrics are used to measure the degree of the focus of the SAR image. To compare the performance of the metric-based SAR autofocus, we also present a detailed analysis of different sharpness metrics. Then, a guide about the optimal sharpness metric in various SAR scenes is presented. The simulation results with the real data demonstrate that the proposed algorithm has better restoration capability in comparison with conventional minimum-entropy algorithm.

Non-steroidal anti-inflammatory drugs and the chemoprevention of colorectal and oesophageal cancers. (1996)

Non-steroidal anti-inflammatory drugs and the chemoprevention of colorectal and oesophageal cancers In recent years, several areas of biological research have increasingly supported the suggestion that aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) may reduce the occurrence or progression of colorectal and, to a lesser extent, oesophageal cancer or both. This suggestion is supported by consistent biochemical, pharmacological, toxicological, clinical, and epidemiological messages. This leading article reviews the evidence and demonstrates how these diverse studies can be translated into strategies for NSAID intervention trials in cohorts at risk of colorectal and oesophageal cancer.

Bioreactors: Design and Operation (1983)

The bioreactor provides a central link between the starting feedstock and the product. The reaction yield and selectivity are determined by the biocatalyst, but productivity is often determined by the process technology; as a consequence, biochemical reaction engineering becomes the interface for the biologist and engineer. Developments in bioreactor design, including whole cell immobilization, immobilized enzymes, continuous reaction, and process control, will increasingly reflect the need for cross-disciplinary interaction in the biochemical process industry.
Reactive Oxygen Species: The Achilles' Heel of Cancer Cells? (2012)

Cancer development, progression, and metastasis are multistep processes. Accumulating evidence suggests that reactive oxygen species (ROS) are critically involved in cancer cell functions. This Forum reviews our current understanding of the important and paradoxical role of ROS in the regulation of tumor-associated cell properties, genes, and signaling pathways. The six reviews in this Forum showcase the up-to-date knowledge on how ROS modulate or interact with the p53 protein, epithelial-mesenchymal transition, tumor stromal cells, angiogenesis, and cancer stem cells, which are essential factors in cancer development and metastasis. The contributions demonstrate that ROS levels in cancer cells are tightly controlled, which brings promises and challenges in the development of novel ROS-targeted anticancer therapies. Further understanding of the biological mechanisms underlying the effects of oxidative stress on tumor growth and metastasis will contribute to the advancement of cancer biology and cancer treatment.
Deactivation of the boron–oxygen recombination center in silicon by illumination at elevated temperature (2008)

Abstract The boron–oxygen‐related recombination center responsible for the light‐induced degradation of solar cells made on boron‐doped oxygen‐contaminated silicon is deactivated by simultaneously annealing the silicon wafer in the temperature range 135–210 °C and illuminating it with white light. The recombination lifetime after deactivation is found to be stable under illumination at room temperature. The deactivation process is shown to be thermally activated with an activation energy of 0.7 eV. Based on the experimental findings, a defect reaction model is proposed explaining the deactivation of the boron–oxygen center. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
