Architecture of FPGA Embedded Multiprocessor Programmable Controller (2014)

This paper presents the design and implementation of a multiprocessor programmable controller in field-programmable gate array (FPGA). The novelty of the proposed solution is that it combines two approaches used so far in the domain of FPGA implementations of control algorithms, i.e., program based and hardware coded, and applies multiple processors in a single FPGA chip. The controller is programmed according to the IEC 61131-3 standard and runs control tasks in parallel. Performance tests of the prototype show that it is able to execute control programs significantly faster than industrial programmable logic controllers.
Regulation of Neurotrophin mRNA Expression in the Rat Brain by Glucocorticoids (1992)

Northern blot analysis was used to examine the effects of glucocorticoids on neurotrophin mRNA expression in the rat cerebral cortex and hippocampus. The results show that 3 days after adrenalectomy the mRNA levels for nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) decreased significantly in both these regions. In adrenalectomized animals given dexamethasone replacement the mRNA levels for the three neurotrophins were restored to control levels. The effect of a single dose of dexamethasone (5 mg/kg) administered i.p. to intact animals on the expression of neurotrophins was also examined. NGF and NT-3 mRNAs showed a 2.5-fold and a 1.4-fold increase, respectively, during the first 4 h after the injection. The increase was followed by a decrease, with levels approximately 50% of control 24 and 48 h after the injection. In contrast, the level of BDNF mRNA did not change during the first 10 h after the injection, but decreased to 70% of control 48 h after the injection. These data indicate that glucocorticoids regulate neurotrophin mRNA expression both in the cortex and in the hippocampus, and suggest further that the known effects of glucocorticoids on neuronal survival in the brain could be due to changes in the levels of neurotrophins in the brain.
Remoting Peripherals using Memory-Mapped Networks (1998)

Memory-mapped networks such as Scalable Coherent Interconnect (SCI) [5] and Memory Channel [4] offer a new method for constructing network peripherals by remoting a host&apos;s IO bus. This paper details our experiences from building such an endpoint, and examines how greater support may be provided. 1 Introduction At ORL we have experimented with an exploded workstation configuration, where low-cost multimedia peripherals known as network end-points are attached directly to an ATM network. End-points include video [3], audio, compact liquid-crystal display [1] and storage devices [2]. Whilst our experience of directly networked peripherals has been encouraging, there were some shortcomings: ffl The backend of a networked peripheral must be heavily re-engineered to interface with the network. This development effort means that networked peripherals are usually behind the state of the art. ffl The use of networked peripherals requires driver reimplementation, even if the peripheral is sup...

Tester stehen oft vor der Aufgabe, Testfälle aus textuellen Anforderungsdokumenten zu erstellen. In der Regel sind diese natürlichsprachlichen Anforderungen nicht formal genug, um daraus automatisch Testfälle zu generieren. In diesem Papier stellen wir ein Werkzeug vor, mit welchem textuelle Anwendungsfallbeschreibungen interaktiv aufbereitet werden können, so dass die anschließende automatisierte Testfallgenerierung möglich wird. Des Weiteren werden die in dem Werkzeug verwendeten Metamodelle beschrieben.
MR Neurography: Advances (2013)

High resolution and high field magnetic resonance neurography (MR neurography, MRN) is shown to have excellent anatomic capability. There have been considerable advances in the technology in the last few years leading to various feasibility studies using different structural and functional imaging approaches in both clinical and research settings. This paper is intended to be a useful seminar for readers who want to gain knowledge of the advancements in the MRN pulse sequences currently used in clinical practice as well as learn about the other techniques on the horizon aimed at better depiction of nerve anatomy, pathology, and potential noninvasive evaluation of nerve degeneration or regeneration.
Analysis on the definition of polarization-dependent loss (2007)

Based on the theory of Mueller matrix of optical devices with both polarization dependent loss (PDL) and birefringence, the definition of polarization loss (PDL) is analyzed. The newly formulated equations for PDL are generalized for input light with arbitrary degree of polarization (DOP). Theoretical derivation shows that the overall polarization states should contain all the polarization states with random DOP. The magnitude of PDL has connection with the input DOP. The direction of PDL vector is only decided by the Mueller matrix.

Particle filter and smoother for indoor localization (2013)

We present a real-time particle filter for 2D and 3D hybrid indoor positioning. It uses wireless local area network (WLAN) based position measurements, step and turn detection from a hand-held inertial sensor unit, floor plan restrictions, altitude change measurements from barometer and possibly other measurements such as occasional GNSS fixes. We also present a particle smoother, which uses future measurements to improve the position estimate for non-real-time applications. A light-weight fallback filter is run in the background for initialization, divergence monitoring and possibly re-initialization. In real-data tests the particle filter is more accurate and consistent than the methods that do not use floor plans. An example is shown on how smoothing helps to improve the filter estimate. Moreover, a floor change case is presented, in which the filter is capable of detecting the floor change and improving the 2D accuracy using the floor change information.
Evaluation of expanded polytetrafluoroethylene (ePTFE) <i>versus</i> polydioxanone (PDS) for the repair of dura mater defects (1999)

A comparative animal experimental study was performed to test the potential application of expanded polytetrafluoroethylene (ePTFE) vs. polydioxanone (PDS) as dural substitutes. Sixty male Sprague-Dawley rats underwent a right frontoparietal craniotomy, opening of the dura mater, and a small cortical lesion. The dural defect was covered with a piece of ePTFE or PDS. Animals were sacrificed at 30 days or 90 days. Following decalcification, heads including scalp, skull, and underlying brain were sectioned, stained with hematoxylin-eosin, and histologically analyzed. Dural defects repaired with ePTFE, showed minimal reactive changes and no adhesions to the brain surface. No foreign body type giant cell reaction was seen, and the graft became enclosed in a thin sheet of connective tissue. Dural defects repaired with PDS, showed some giant cell infiltration and ingrowth of collagen fibers. Both substitutes provided satisfactory biological function and biocompatibility. Expanded PTFE advantages included relative suppression of tissue ingrowth, ensheathment by connective tissue, and a high tearing strength. Although both materials show promise for use in dural grafting, further clinical studies are necessary to determine their potential applications as a human dural substitute.
BOLD cardiovascular magnetic resonance at 3.0 tesla in myocardial ischemia (2010)

<title>Sideband generators for submillimeter-wave applications</title> (1999)

Sideband generation is a method for producing tunable sources in the far IR frequency range by mixing a tunable microwave source with a fixed laser source to produce tunable sidebands. A 36 element array of planar Schottky diodes was used to mix the output of a CO<SUB>2</SUB> pumped laser at 1.6 THz with a 1-20 GHz microwave source to generate 5.9 (mu) W of DSB power for a conversion efficiency of 28 dB. The array produces sidebands by modulating the amplitude of the laser with a low duty cycle and no matching network which is not the optimal condition. For unmatched conditions at 180 degree phase modulation by a square wave with a 50 percent duty cycle will provide 4 dB SB conversion efficiency. This can be implemented by resonating an inductor with a varactor to obtain a short circuit and then modulating away form resonance for an open circuit. A proof of principle demonstration was implemented in waveguide at 80 GHz which resulted in 9 dB conversion efficiency for sinusoidal phase modulation and about 3 GHz bandwidth. This technique will be attempted at 1.6 THz in waveguide.
Inhibition of Human Breast Cancer Cell Growth and Enzymatic Activity by a Fermented Nutraceutical (2009)

Human breast cancer cell lines MCF-7 (ER-positive) and Hs578T (ER-negative) were cultured and one lot incubated for 48 h with 5-50 mug/ml of a fermented phytocompound (MK: Manda-Koso, Innoshima, Japan). In vitro, it appeared a dose-dependent decrease of cell viability (5-57%) in MK group in both cell lines (P < 0.001, plateau: 30 microg/ml), decreased beta-galactosidase activity, enhanced apoptosis, and inversely increased Bax/Bcl2 ratio (P < 0.01) with an upregulation of p53 (P < 0.05). In the in vivo model, Balb-c mice were inoculated with tumor cells and the treatment group was fed with 20 mg of MK. Tumor weight in MK-fed group was time-course reduced by 22% to 51% at 2 and 4 weeks, respectively (P < 0.05) with increased survival (P < 0.05). Tumour tissue of MK-fed mice showed a downregulated Bcl-2 with increased Bax/Bcl-2 ratio, reduced PCNA, and activated caspase 3. Although more studies are ongoing to foster the clinical applicability of MK integrated within a rational chemopreventive and therapeutic strategy, a p53-mediated mechanism is likely to play a relevant role, besides its reported antioxidant capacity, NK cell activity enhancement, cancer-cytostatic activity properties.
MoS<sub>2</sub> Quantum Dot-Interspersed Exfoliated MoS<sub>2</sub> Nanosheets (2014)

We report the synthesis of heterodimensional nanostructures of MoS2 quantum dots interspersed in few-layered sheets of MoS2, using a liquid exfoliation technique in organic solvents. This unique hybrid morphology results from the optimized experimental conditions involving bath sonication followed by ultrasound probe sonication. We show that such heterodimensional hybrid materials could easily be extracted from the solvent as precipitates when post-treated with less polar volatile solvents such as chloroform. Such tailored MoS2 nanostructures, when directly used as electrodes for hydrogen evolution reaction, showed excellent electrocatalytic activity with low overpotential. Hence, we believe this could lead to large-scale synthesis of liquid-exfoliated layered nanostructures for their potential applications.
Crc Is Involved in Catabolite Repression Control of the <i>bkd</i> Operons of <i>Pseudomonas putida</i> and <i>Pseudomonas aeruginosa</i> (2000)

Crc (catabolite repression control) protein of Pseudomonas aeruginosa has shown to be involved in carbon regulation of several pathways. In this study, the role of Crc in catabolite repression control has been studied in Pseudomonas putida. The bkd operons of P. putida and P. aeruginosa encode the inducible multienzyme complex branched-chain keto acid dehydrogenase, which is regulated in both species by catabolite repression. We report here that this effect is mediated in both species by Crc. A 13-kb cloned DNA fragment containing the P. putida crc gene region was sequenced. Crc regulates the expression of branched-chain keto acid dehydrogenase, glucose-6-phosphate dehydrogenase, and amidase in both species but not urocanase, although the carbon sources responsible for catabolite repression in the two species differ. Transposon mutants affected in their expression of BkdR, the transcriptional activator of the bkd operon, were isolated and identified as crc and vacB (rnr) mutants. These mutants suggested that catabolite repression in pseudomonads might, in part, involve control of BkdR levels.
Lowering the UV Absorbance Detection Limit in Capillary Zone Electrophoresis Using a Single Linear Photodiode Array Detector (1998)

A new approach for lowering the UV absorbance detection limit in capillary electrophoresis is presented. This approach involves the use of a photodiode array in which each of the diodes in the array is treated as an independent detector. Over the course of a run, therefore, an electropherogram is generated for each diode in the array. Averaging the electropherograms generated from 1500 diodes in a diode array resulted in a signal-to-noise ratio 85 times that of an electropherogram generated from any one diode in the array. These signal-to-noise improvements are discussed, and the detection limits are compared to the detection limits obtained from a commercial single-point detector. The array detector improves the detection limit by a factor of 3.8 (±0.4).
Architecture Concepts and Technical Issues for an Open, Interoperable Automated Demand Response Infrastructure (2007)

This paper presents the technical and architectural issues associated with automating Demand Response (DR) programs. The paper focuses on a description of the Demand Response Automation Server (DRAS), which is the main component used to automate the interactions between the Utilities and their customers for DR programs. Use cases are presented that show the role of the DRAS in automating various aspects of DR programs. This paper also describes the various technical aspects of the DRAS including its interfaces and major modes of operation. This includes how the DRAS supports automating such Utility/Customer interactions as automated DR bidding, automated DR event handling, and finally real-time pricing.
Surface-enhanced Raman scattering effects of gold nanorods prepared by polycarbonate membranes (2013)

Using a polycarbonate membrane (PCM) as a template, and combining with the electrochemical deposition method, we prepare gold nanorods each with about 36 nm in diameter and 1 μrm in length. We measure transmission spectra, and find that the resonant absorption peak is at around 540 nm. Subsequently, the enhancement effects of the nanorods are investigated with 514 nm and 633 nm laser excitations. Comparing the spectra under resonant condition with those under non-resonant condition, we conclude that the field enhancement effect under the resonant excitation is more prominent than under the non-resonant excitation. The enhancement factor under the resonant excitation is increased to 7 times of the factor under the non-resonant excitation. Comparing with similar researches, we achieve the following two improvements: 1) with a resonant excitation, we significantly increase the enhancement factor of gold nanorods; 2) we eliminate the fluorescence of PCM molecules, thus make the template method more feasible for transparent surface-enhanced Raman scattering substrate applications.
Mentha piperita (Peppermint) (2010)

PEPPERMINT (Mentha piperita) is a popular herb that can be used in numerous forms (ie, oil, leaf, leaf extract, and leaf water). Peppermint oil has the most uses, and use data on the oil are considered relevant to the leaf extract formulations as well. This herbal preparation is used in cosmeceuticals, personal hygiene products, foods, and pharmaceutical products for both its flavoring and fragrance properties. Peppermint oil possesses a fresh sharp menthol odor and a pungent taste followed by a cooling sensation. It also has a variety of therapeutic properties and is used in aromatherapy, bath preparations, mouthwashes, toothpastes, and topical preparations. Topical preparations of peppermint oil have been used to calm pruritus and relieve irritation and inflammation. Their frequent application to impaired skin could contribute to the sensitization rates seen. Numerous allergic contact dermatitis reactions to peppermint oil have been described, many of which are linked to both perioral and intraoral disorders. Although peppermint oil is known for its many properties, its role as a sensitizer should be recognized so as to aid in the diagnosis of both dermatitis and oral conditions and to allow the initiation of proper avoidance measures.
Dielectric cell separation of fine needle aspirates from tumor xenografts (2008)

As an approach to isolating tumor cells from fine needle biopsy specimens, we investigated a dielectric cell preparation method using an in vivo xenographic tumor model. Cultured human MDA-MB-435 tumor cells were grown as solid tumors in nude mice and fine needle aspiration biopsies were conducted. Biopsied cells were suspended in sucrose medium and collected on slides patterned with microelectrode arrays (electrosmears) energized by electrical signals in the range 10 to 960 kHz. The unlabeled cells adhered to characteristic regions of the slides in accordance with their morphology as a result of dielectric forces. Tumor cells were trapped between 40 and 60 kHz and were separated according to whether they were mitotic, large and complex, or small. Damaged tumor cells were captured at between 60 and 120 kHz; granulocytes between 70 and 90 kHz; lymphocytes between 85 and 105 kHz; healthy erythrocytes between 140 and 180 kHz, and damaged erythrocytes above 180 kHz. Using intrinsic cell characteristics, the electrosmear presented cell subpopulations from fine needle aspiration biopsy specimens in a manner that is compatible with automated slide-based analysis systems. The approach has the potential to facilitate the analysis of the role of cell subpopulations in disease.
Label-free aptamer-based sensor using abasic site-containing DNA and a nucleobase-specific fluorescent ligand (2009)

A label-free adenosine sensor with emissive response is designed based on an AP site-containing aptamer/DNA duplex and a small fluorescent molecule 2-amino-5,6,7-trimethyl-1,8-naphthyridine (ATMND).
Sizing the Holin Lesion with an Endolysin-β-Galactosidase Fusion (2003)

Double-stranded DNA phages require two proteins for efficient host lysis: the endolysin, a muralytic enzyme, and the holin, a small membrane protein. In an event that defines the end of the vegetative cycle, the lambda holin S acts suddenly to permeabilize the membrane. This permeabilization enables the R endolysin to attack the cell wall, after which cell lysis occurs within seconds. A C-terminal fusion of the R endolysin with full-length beta-galactosidase (beta-Gal) was tested for lytic competence in the context of the late-gene expression system of an induced lambda lysogen. Under these conditions, the hybrid R-beta-Gal product, an active tetrameric beta-Gal greater than 480 kDa in mass, was fully functional in lysis mediated by the S holin. Western blot analysis demonstrated that the lytic competence was not due to the proteolytic release of the endolysin domain of the R-beta-Gal fusion protein. The ability of this massive complex to be released by the S holin suggests that S causes a generalized membrane disruption rather than a regular oligomeric membrane pore. Similar results were obtained with an early lysis variant of the S holin and also in parallel experiments with the T4 holin, T, in an identical lambda context. However, premature holin lesions triggered by depolarization of the membrane were nonpermissive for the hybrid endolysin, indicating that these premature lesions constituted less-profound damage to the membrane. Finally, a truncated T holin functional in lysis with the endolysin is completely incompetent for lysis with the hybrid endolysin. A model for the formation of the membrane lesion within homo-oligomeric rafts of holin proteins is discussed.

Capturing the Design Space of Sequential Space-Filling Layouts (2012)

We characterize the design space of the algorithms that sequentially tile a rectangular area with smaller, fixed-surface, rectangles. This space consist of five independent dimensions: Order, Size, Score, Recurse and Phrase. Each of these dimensions describe a particular aspect of such layout tasks. This class of layouts is interesting, because, beyond encompassing simple grids, tables and trees, it also includes all kinds of treemaps involving the placement of rectangles. For instance, Slice and dice, Squarified, Strip and Pivot layouts are various points in this five dimensional space. Many classic statistics visualizations, such as 100% stacked bar charts, mosaic plots and dimensional stacking, are also instances of this class. A few new and potentially interesting points in this space are introduced, such as spiral treemaps and variations on the strip layout. The core algorithm is implemented as a JavaScript prototype that can be used as a layout component in a variety of InfoViz toolkits.
A new medical microrobot for minimal invasive surgery (2001)

A new medical microrobot to drive endoscopes into endocoeles is presented. The structure of the microrobot is very simple; it consists of a right spirally grooved micromotor, a left spirally grooved cylinder and a flexible coupling. When the micromotor rotates, a hydrodynamic mucus film is formed because highly viscous mucus exists in endocoeles. The mucus film can prevent direct contact between the microrobot and the endocoele, and the injury to organic tissues may be avoided. The locomotion speed and the hydrodynamic mucus film thickness formed when the microrobot drives endoscopes into endocoeles have been calculated according to hydrodynamic lubrication theory. The results indicate that the microrobot can be suspended to drive endoscopes quickly into endocoeles. This has been confirmed by experiments.
Availability of coding based replication schemes (2003)

The availability of a coding-based replication scheme where simple voting is used to maintain correctness of replicated data is evaluated. It is shown that the storage requirement for maintaining the data with a given availability is reduced significantly. The ways that some of the extensions of the voting scheme can be modified to manage this coding-based replication are also described. The availability of these is evaluated, and the reduction in the storage space requirements achieved is studied.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
