FS-ALOHA++, a collision resolution algorithm with QoS support for the contention channel in multiservices wireless LAN (2003)

FIFO by sets ALOHA (FS-ALOHA) is a collision resolution algorithm for the uplink contention channel in multiservices wireless LANs. FS-ALOHA builds sets with the requests generated by the mobiles on a per-frame basis and serves them using slotted ALOHA with a FIFO discipline. In this paper the overall performance (throughput and delay) of FS-ALOHA is improved by serving the sets in groups. Furthermore, FS-ALOHA++ is provided with a threshold mechanism allowing the support of two distinct traffic classes, a high priority class with low delay requirements and a best-effort, low priority class. The performance of FS-ALOHA++ is analyzed via simulation.

Randomized routing of virtual connections in essentially nonblocking log N-depth networks (1995)

An optimal N/spl times/N circuit switching network with /spl theta/(N/spl times/N) bandwidth has a lower bound of /spl theta/(N/spl middot/log N) hardware, which includes all crosspoints, bits of memory and logic gates, and a lower bound of /spl theta/(logN) set-up time. To date no known self-routing circuit switching networks with explicit constructions achieve these lower bounds. The authors consider a randomized routing algorithm on a class of circuit switching networks called "extended dilated banyans". It is proven that the blocking probability of an individual connection request is O[log/sub b/ N/spl middot/(k/d)/sup d/], where d is the dilation factor and k is a constant. With a dilation of /spl theta/(log log N) and a loading <1 the blocking probability is shown to approach zero, yielding an "essentially nonblocking" network. The hardware complexity of these networks depends upon the internal node implementation. A space division node yields a network with /spl theta/(N/spl middot/log N/spl middot/log log N) hardware and /spl theta/(log N/spl middot/log log N) set-up time. A time division node, in which the bits from each connection are dynamically concentrated in time using a "time-bit-concentrator" circuit, yields a network with an asymptotically optimal O(N/spl middot/log N) hardware and a slightly suboptimal /spl theta/(log N/spl middot/log log N) set-up time. Both implementations improve upon the best known explicit constructions of self-routing circuit switching networks with /spl theta/(N) bandwidth, and the TDM construction meets Shannon's lower bound on the cost of such networks. It is shown that extended dilated banyans can carry significantly more traffic than the Batcher-banyan switch and its variants.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Profiling Solute Carrier Transporters in the Human Blood–Brain Barrier (2013)

The neuroprotective function of the blood-brain barrier (BBB) presents a major challenge for drug delivery to the central nervous system (CNS). Critical to this function, BBB membrane transporters include the ATP-binding cassette (ABC) transporters, which limit drug penetration across the BBB, and the less-well-studied solute carrier (SLC) transporters. In this work, expression profiling of 359 SLC transporters, comparative expression analysis with kidney and liver, and immunoassays in brain microvessels (BMVs) identified previously unknown transporters at the human BBB.
A New Correlation to Calculate Oil-Water Interfacial Tension (2012)

Abstract The oil-water interfacial tension (IFT) is by all means important in capillary pressure estimation and fluid-fluid and fluid-rock interactions analysis. Observations from experimental data indicate that oil-water IFT is a function of pressure, temperature, and compositions of oil and water. A reliable correlation to estimate oil-water IFT is highly desire. Unfortunately to our best knowledge no correlation that uses the compositions of oil and water as inputs is available. Our work is to fill this gap. In this research, we collected data from former studies and investigations and developed a correlation for oil-water IFT. In the proposed correlation oil-water IFT is a function of system pressure, temperature, and compositions of oil and water. Error analysis was conducted to check the accuracy of the equation by comparing the calculated values with the experimental data. The results indicated that the new correlation predicts reliable oil-water IFTs. Our correlation calculates the oil-water IFT from system pressure, temperature, and compositions of oil and water. It addresses the effect of composition of oil on IFT, which is not presented in existing correlations. Therefore it can not only be applied in the calculation of capillary pressure in the compositional simulation, but also be used in daily petroleum engineering calculation such as waterflooding analysis.
Hearing every footstep: Noise sensitivity in individuals following traumatic brain injury (2012)

Noise sensitivity is an important and under-researched symptom that can result from traumatic brain injury (TBI). Interpretative phenomenological analysis (IPA) was used to analyse the experiences of noise sensitivity of six individuals with TBI. The results revealed four major themes through which participants described a process of having to find information for themselves to understand what they were experiencing and their changed relationship with sounds. The participants also described feeling overwhelmed as they struggled to cope with the changes to their lives and being able to plan and take some control over their lives. The findings are of importance for both health professionals involved in rehabilitation and individuals recovering from TBI.
A white LED backlight driving IC with 3-bit dimming controller (2011)

This paper presents a white LED backlight driving chip with 3-bit dimming controller and duty-variable power MOS which can be modified with the voltage-mode pulse width modulation (PWM). In the proposed chip, a 3-bit digital-to-analog converter (DAC) and a ramp generator are used to provide eight pulses with variable width through a voltage comparator. Thus, a 3-bit dimming controller can be implemented with those duty cycles for white LED backlight driver. In this paper, the proposed chip is designed and implemented with TSMC 0.35 µm 2P4M CMOS process. The simulation results of the switching DC-DC boost converter show that the output voltage, output current, and chip area are 20 V, 20 mA, and 1.45×1.28 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , respectively, at the supply voltage of 3.7 V. The output voltage of 20 V can drive five white LEDs because that a white LED works with a driving voltage of 3.5 V and a driving current of 20 mA.
Porcine mitral valve interstitial cells in culture. (1988)

There are connective tissue cells present within the interstitium of the heart valves. This study was designed to isolate and characterize mitral valve interstitial cells from the anterior leaflet of the mitral valve. Explants obtained from the distal part of the leaflet, having been scraped free of surface endocardial cells, were incubated in medium 199 supplemented with 10% fetal bovine serum. Cells grew out of the explant after 3 to 5 days and by 3 weeks these cells were harvested and passaged. Passages 1 to 22 were characterized in several explant sets. The cells showed a growth pattern reminiscent of fibroblasts. Growth was dependent on serum concentration. Cytoskeletal localization of actin and myosin showed prominent stress fibers. Ultrastructural studies showed many elongated cells with prominent stress fibers and some gap junctions and few adherens junctions. There were as well cells with fewer stress fibers containing prominent Golgi complex and dilated endoplasmic reticulum. In the multilayered superconfluent cultures, the former cells tended to be on the substratum of the dish or surface of the multilayered culture, whereas the latter was generally located within the layer of cells. Extracellular matrix was prominent in superconfluent cultures, often within the layers as well. Labeling of the cells with antibody HHF 35 (Tsukada T, Tippens D, Gordon D, Ross R, Gown AM: Am J Pathol 126:51, 1987), which recognizes smooth muscle cell actin, showed prominent staining of the elongated stress fiber-containing cells and much less in the secretory type cells. These studies show that interstitial mitral valve cells can be grown in culture and that either two different cell types or one cell type with two phenotypic expressions is present in culture.
Expression of the Tobacco <i>Ext 1.4</i> Extensin Gene Upon Mechanical Constraint and Localization of Regulatory Regions (2001)

Abstract: The regulation of the Ext 1.4 gene encoding a tobacco ( Nicotiana tabacum L.) extensin was studied in response to mechanical constraints. Transgenic plants carrying chimeric Ext 1.4 promoter/GUS (β‐glucuronidase)/ nos terminator or Ext 1.4 3′‐end constructs were obtained. Expression of gene fusions was found in tissues where mechanical stresses occur, e.g., during germination, as well as in root and stem tissues. Chimeric genes were successively and transiently expressed in different tissues during germination, i.e., at the tip of the root and then in the hypocotyl, during their growth through the seed coat. Moreover, they were expressed in cortical cells surrounding the emergence of adventitious and lateral roots and developmentally‐regulated in nodes. The expression of Ext 1.4 could be induced by imposing mechanical constraints due to curving of either the stems or roots. Expression then occurred in cells where it does not normally occur, i.e., in cortical cells of internodes and in the distal piliferous zone of roots. Accumulation of RNAs occurs several days after the start of the constraint. Promoter regions involved in regulation of expression of Ext 1.4 in stems, roots, and in seedlings upon mechanical constraint could be localized. Moreover, the 3′ non‐coding region was shown to modulate expression in roots. These results suggest that the regulation of Ext 1.4 following mechanical stress is dependent on both tissue‐specific and mechanical‐responsive elements.
Dosimetric advantages of intensity modulated radiation therapy in locally advanced lung cancer (2017)

IMRT significantly decreased unnecessary dose to critical organs with equivalent coverage of planning target volumes. IMRT may therefore improve the tolerability of therapy.
HRRI: a high resolution radioimager for fast, direct quantification in in situ hybridization experiments. (1994)

We present a high-speed, high-resolution beta imager. It has been developed to be used in in situ hybridization experiments, either instead of or in complement with autoradiographic film and emulsions that are currently used for these experiments. It allows the user to locate and perform quantitative analyses of (3H-, 14C-, 35S-, 32P-, 125I-) labeled molecules with a 15-microns spatial resolution on a 1.2 cm2 area. We have combined recent techniques (specific scintillator thin sheets and intensified charge-coupled device [CCD]) so that this imager offers a wide dynamic range and real-time acquisition. Several biological applications will be discussed.

Bottom-Up Self-Organization of Unpredictable Demand and Supply under Decentralized Power Management (2008)

In the DEZENT project we had established a distributed base model for negotiating electric power from widely distributed (renewable) power sources on multiple levels in succession. Negotiation strategies would be intelligently adjusted by the agents, through (distributed) reinforcement learning procedures. The distribution of the negotiated power quantities (under distributed control as well) occurs such that the grid stability is guaranteed, under 0.5 sec. The major objective in this paper was to deal, on the same level of granularity, with short-term power balance fluctuation, in terms of a peak demand and supply management exhibiting highly dynamic, self-organizing, autonomous yet coordinated algorithms under fine-grained distributed control. Our extensive experiments show very clearly that these short-term fluctuations could be leveled down by 70 - 75 %. In this way we have tackled, for the quickly increasing renewable power systems, a crucial problem of its stability, in a novel way that scales very easily due to the completely decentralized control.
Palladium-Catalyzed <i>anti</i>-Hydrothiolation of 1-Alkynylphosphines (2007)

The Tomato Fruit Cell Wall (1990)

A nonsoftening tomato (Lycopersicon esculentum L.) variety, dg, was examined to assess the physiological basis for its inability to soften during ripening. Total uronic acid levels, 18 milligrams uronic acid/100 milligrams wall, and the extent of pectin esterification, 60 mole%, remained constant throughout fruit development in this mutant. The proportion of uronic acid susceptible to polygalacturonase in vitro also remained constant. Pretreatment of heat-inactivated dg fruit cell walls with tomato pectinmethylesterase enhances polygalacturonase susceptibility at all ripening stages. Pectinesterase activity of cell wall protein extracts from red ripe dg fruit was half that in extracts from analogous tissue of VF145B. Polygalacturonase activities of cell wall extracts, however, were similar in both varieties. Diffusion of uronic acid from tissue discs of both varieties increased beginning at the turning stage to a maximum of 2.0 milligrams uronic acid released/gram fresh weight at the ripe stage. The increased quantity of hydrolytic products released during ripening suggests the presence of in situ polygalacturonase activity. Low speed centrifugation was employed to induce efflux of uronide components from the cell wall tree space. In normal fruit, at the turning stage, 2.1 micrograms uronic acid/gram fresh weight was present in the eluant after 1 hour, and this value increased to a maximum of 8.2 micrograms uronic acid/gram fresh weight at the red ripe stage. However, centrifuge-aided extraction of hydrolytic products failed to provide evidence for in situ polygalacturonase activity in dg fruit. We conclude that pectinesterase and polygalacturonase enzymes are not active in situ during the ripening of dg fruit. This could account for the maintenance of firmness in ripe fruit tissue.
Multimodal Image Registration Using a Variational Approach (2003)

This paper presents an approach to obtain a deformation which matches two images acquired from different medical imaging modalities. This problem arises in the investigation of human brains. Two distance functionals for the images are proposed with different pros and cons. These functionals are to be minimized. We add a smoothing term to the minimization problem which retains certain desired elastic features in the solution. At each minimization step an approximate solution for the linearized problem is computed with a multigrid method as an inner iteration. Furthermore, we use a multiresolution minimization approach to obtain a suitable initial guess. Finally, we present some experimental results for registration problems of synthetic images and for a real computer tomography (CT)--magnetic resonance imaging (MRI) registration.
Control of metal-insulator transition temperature in VO2 thin films grown on RuO2/TiO2 templates by strain modification (2019)

Ruthenium dioxide (RuO2) is an ideal buffer layer for vanadium dioxide (VO2) heterostructures due to its high electrical conductivity and matching crystal structure with metallic VO2. VO2 thin films were deposited on single crystal TiO2 (001) substrates with RuO2 buffer layers via pulsed laser deposition. The metal-insulator transition temperature (TMIT) in VO2 films can be controlled by the epitaxial strain between the VO2 film and RuO2 buffer layer by adjusting the buffer layer thickness (10 - 50 nm). We observed a decrease in the TMIT of VO2 films from 59 °C to 24 °C as the RuO2 thickness decreased from 50 nm to 10 nm. Additionally, we show that the RuO2 buffer layer can sustain an intermediate strain state in VO2 films up to 100 nm in thickness with a subsequently lower TMIT (30 °C). The 10 nm thick RuO2 buffer layer can reduce the TMIT in VO2 films by providing a pathway to relieve the strain through grain boundaries.

Calcitonin gene‐related peptide (CGRP) is a potent non‐endothelium‐dependent inhibitor of coronary vasomotor tone (1987)

1 Ring segments of bovine left circumflex coronary artery were pre-contracted with 5-hydroxytryptamine or phenylephrine and then exposed to increasing concentrations of calcitonin gene-related peptide (CGRP) and other drugs. 2 CGRP administration resulted in dose-dependent inhibition of induced tone. Maximal relaxation to CGRP was 89 +/- 5% and the concentration required to achieve 50% maximal relaxation (EC50) was 2.11 +/- 1.35 X 10(-9)M. 3 CGRP-induced relaxation was not affected by removal of endothelial cells nor was it significantly altered by incubation of coronary vessels with atropine, propranolol, phentolamine (all 10(-6)M) or indomethacin (10(-5)M). 4 From these data we conclude that CGRP is a potent inhibitor of coronary artery vasomotor tone which appears to act directly on vascular smooth muscle rather than through the release of a secondary mediator. These data support the possibility that CGRP may play a role in non-adrenergic, non-cholinergic regulation of coronary artery tone.
ROAD WEATHER INFORMATION SYSTEMS: ENABLING PROACTIVE MAINTENANCE PRACTICES IN WASHINGTON STATE (2002)

Washington State Department of Transportation's (WSDOT's) program has significantly integrated and expanded the capabilities of road weather information systems (RWISs) in the state, enabling proactive winter maintenance practices and better-informed winter travel decisions. The report reviews the potential benefits of a comprehensive, integrated RWIS, including cost-efficient snow and ice control strategies and improved safety and mobility. Use of, and attitudes toward, RWIS by WSDOT maintenance personnel are examined, and barriers to the expanded use of RWIS technologies are identified. Public response to the rWeather traveler information website is evaluated. Recommendations are presented for more fully utilizing RWIS capabilities.
Energy-Efficient Processor for Blind Signal Classification in Cognitive Radio Networks (2013)

Blind modulation classification is of vital importance in spectrum surveillance applications and future heterogeneous wireless networks. In standardized wireless systems, modulation classification can be performed through exhaustive search of known signal features. Most commonly used classifiers are based on the detection of cyclostationary features, which are second-order moments of a signal, related to its carrier and symbol rate. However, when the signal parameters are unknown, an exhaustive search for cyclostationary features is energy inefficient due to high computational complexity. In this paper, we present a reconfigurable processor architecture that can blindly classify any linearly modulated signal (M-QAM, M-PSK, M-ASK, and GMSK) in addition to multi-carrier signals and spread spectrum signals. The contributions of this work are twofold. First, we analyze the complexity tradeoffs among different dependent signal processing kernels in order to minimize the total processing time and energy. Second, we optimize the processor architecture by the co-design methodology to enhance block reusability and reconfigurability. The proposed processor has been verified and synthesized in a 40-nm CMOS technology with core area of 0.06 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and power dissipation of 10 mW under 0.9 V supply voltage at 500 MHz. Under a 500 MHz wide-band signal at 10 dB SNR, a complete blind classification process consumes 10.37 μJ to meet 95% of classification accuracy.
Clinical applications of hematopoietic growth factors. (1994)

In the past eight years, the hematopoietic growth factors have been used in a variety of clinical settings. They have proven to be effective in stimulating marrow proliferation, increasing circulating blood cell counts, and stimulating various host defense mechanisms. Others are in earlier stages of clinical studies, and their full therapeutic potential remains to be evaluated. New therapies are expected to emerge at a rapid pace.
Hexacyanometalate Salt Complexes as Catalysts for Epoxide Polymerizations (1973)

The discovery, compositions, and physical and catalytic properties of a new class of complexes of certain hexacyanometalate salts are reported here. A typical example consists of the nonstoichiometric complex Zn3[Co(CN)6]2 · x[glyme] · yZnCl2 · zH2O. These complexes are catalysis for preparing high-molecular-weight, amorphous, polypropylene oxide); poly(propylene ether) polyol having a narrow molecular-weight distribution; and polyesters from the copolymerization of epoxides and cyclic anhydrides. The data presented indicate that these catalysts operate according to a coordinate mechanism.
The refractive index of InP and its temperature dependence in the wavelength range from 1.2 {micro}m to 1.6 {micro}m (1996)

Measurements of the refractive index of InP in the wavelength range from 1.2 {micro}m to 1.6 {micro}m have been carried out with a relative accuracy of 2 {times} 10{sup {minus}4}. The refractive indices are determined from the measured transmission wavelengths of an n{sup {minus}}/n{sup +}-InP demultiplexer and their temperature dependence. The refractive indices are found to vary linearly with temperature with a coefficient between 2.3 and 1.9 {times} 10{sup {minus}4}/K. The results are compared with data from literature.
Über das Selbstverständnis der Pädagogik als Wissenschaft (2011)

Was ist Pädagogik? Eine der vielleicht wichtigsten Fragen wissenschaftlicher Pädagogik ist die nach ihrem Wissenschaftscharakter und nach ihrem eigenen Selbstverständnis. Denn nicht zuletzt wird daran ihre Bedeutung für die pädagogische und gesellschaftliche Praxis gemessen und ihre Stellung gegenüber den anderen Wissenschaften ausgewiesen. Angesichts der Erwartungen und der Kritik, mit der sich wissenschaftliche Pädagogik immer wieder konfrontiert sieht, angesichts der Vielzahl unterschiedli...
