Subpixel edge localization and the interpolation of still images (1995)

In this paper, we present a nonlinear interpolation scheme for still image resolution enhancement. The algorithm is based on a source model emphasizing the visual integrity of detected edges and incorporates a novel edge fitting operator that has been developed for this application. A small neighborhood about each pixel in the low-resolution image is first mapped to a best-fit continuous space step edge. The bilevel approximation serves as a local template on which the higher resolution sampling grid can then be superimposed (where disputed values in regions of local window overlap are averaged to smooth errors). The result is an image of increased resolution with noticeably sharper edges and, in all tried cases, lower mean-squared reconstruction error than that produced by linear techniques.
Development of a Bench-Scale High-Pressure Fluidized Bed Reactor and Its Sequential Modification for Studying Diverse Aspects of Pyrolysis and Gasification of Coal and Biomass (2008)

This paper reviews the design, operation, and sequential modifications of a bench-scale high-pressure fluidized bed reactor system, capable of diverse pyrolysis and gasification applications, all based on the same hardware platform. The reactor is small: 34 mm i.d. and 504 mm high. The mechanical design is relatively simple and inexpensive, featuring direct electrical heating to avoid the use of a separate furnace. The reactor body is made of a high-strength alloy, with 1000 h creep resistance at maximum design conditions (1000 °C and 3.0 MPa). The design thus obviates the use of a “cold” pressure casing. The system can be operated by a single person and has demonstrated ability to generate fuel reactivity and product distribution data rapidly and cheaply, using a wide range of solid fuels. In batch operation, conversions achieved during coal pyrolysis and gasification experiments were comparable with results from a high-pressure wire-mesh reactor, indicating nearly single-particle behavior. The system has been modified for continuous feeding (∼3 g min −1), to study the effect of reaction conditions on the fate of fuel-N, during the gasification of coal and sewage sludge (to 3.0 MPa). The work showed that steam plays a primary role in the formation of NH 3 from both volatile-N and char-N. HCN concentrations were found to depend strongly on the residence time at temperature and on the extent of contact with heated bed solids. A quartz lining allowed the determination of extents of trace element emissions during gasification. Above 900 °C, enhanced depletion of Ba, Pb, and Zn in bed solids was accompanied by enrichment of fines, collected in a downstream filter. The system was subsequently modified to enable a slug of coal to be injected and bed solids discharged (1−3.0 MPa) from the fluidized bed under controlled conditions and precise solid residence times in the bed. The reactivities of the chars were measured as a function of “residence time at temperature” and were observed to decrease with increasing temperature, time, pressure, and particle size. At 1000 °C, coal char reactivities were found to diminish by nearly a factor of 4 within 10 s. The study confirmed and extended prior work carried out in a high-pressure wire-mesh reactor. The system was subsequently configured for pyrolyzing waste plastic material at low temperatures. Altering the electrode positions enabled changing the position of the heated zone, enabling trouble-free injection of polymer samples at temperatures up to 600 °C. The aim of these experiments was to investigate the potential to produce liquid fuel precursors from pure and mixed waste plastics. In its latest incarnation the system has been further modified for performing oxy-fuel gasification experiments.
Downlink admission control for multimedia services in WCDMA (2003)

A call admission control (CAC) scheme for downlink multimedia services in a WCDMA system is proposed. Admission control based on instantaneous measurements may cause capacity loss and quality of service (QoS) degradation because of abrupt fluctuations of the power level at the base station (BS). Instead, both the average power level of real-time circuit services and the average queue size of non-real-time packet services are considered in our scheme. The performance of the proposed admission control scheme is investigated by simulation results in terms of, e.g., blocking probability, outage probability, average throughput, and average queue size.
ATOMIC AND ELECTRONIC STRUCTURES OF GLASSY GeXSe1-X AROUND THE STIFFNESS THRESHOLD COMPOSITION (2001)

Anomalous x-ray scattering experiments on glassy GexSe1-x have been carried out at energies close to the Ge and Se K edges at concentrations close to the onset and completion of the rigidity percolation threshold (x = 0.195 and 0.23). The total structure factors S(Q) show rapid changes in both the position and intensity of the prepeak around 10 nm-1, while remaining almost unchanged in the other Q ranges. The differential structure factors ∆iS(Q) obtained have characteristic features of their own. A detailed comparison among them suggests that the prepeak originates from only the Ge-Ge correlation. On the basis of the concentration dependence of the spectra and the existing partial structure factors of glassy GeSe2 obtained by Petri et al., the origin of the prepeak is discussed. Valence- and conduction-band electronic density of states of glassy GexSe1-x (0 x 0.33) were also investigated by measuring the ultraviolet photoemission and inverse-photoemission spectra. They exhibit a remarkable change in their spectral features near x = 0.20. These observations in both the atomic and electronic structures are consistent with the occurrence of a percolation threshold in non-crystalline covalent network systems as predicted by Phillips and Thorpe. The threshold is characterized by the percolation of a specific Ge(Se1/2)4 molecular unit spread over the network.
Solid Solubilities of Impurity Elements in Germanium and Silicon* (1960)

The available data on solid solubilities of impurity elements in germanium and silicon are summarized in the form of solidus or solvus curves. New solubility data are presented for the lead-germanium, zinc-germanium, indium-germanium, antimony-silicon, gallium-silicon and aluminum-silicon systems. The correlation of the solid solubilities with the heats of sublimation and the atom sizes of the impurity elements is considered.

Non-Smad Transforming Growth Factor-β Signaling Regulated by Focal Adhesion Kinase Binding the p85 Subunit of Phosphatidylinositol 3-Kinase (2011)

TGF-β modulates numerous diverse cellular phenotypes including growth arrest in epithelial cells and proliferation in fibroblasts. Although the Smad pathway is fundamental for the majority of these responses, recent evidence indicates that non-Smad pathways may also have a critical role. Here we report a novel mechanism whereby the nonreceptor tyrosine focal adhesion kinase (FAK) functions as an adaptor necessary for cell type-specific responses to TGF-β. We show that in contrast to Smad actions, non-Smad pathways, including c-Abl, PAK2, and Akt, display an obligate requirement for FAK. Interestingly, this occurs in Src null SYF cells and is independent of FAK tyrosine phosphorylation, kinase activity, and/or proline-rich sequences in the C-terminal FAT domain. FAK binds the phosphatidylinositol 3-kinase (PI3K) p85 regulatory subunit following TGF-β treatment in a subset of fibroblasts but not epithelial cells and has an obligate role in TGF-β-stimulated anchorage-independent growth and migration. Together, these results uncover a new scaffolding role for FAK as the most upstream component regulating the profibrogenic action of TGF-β and suggest that inhibiting this interaction may be useful in treating a number of fibrotic diseases.
Light-actuated digital microfluidics for large-scale, parallel manipulation of arbitrarily sized droplets (2010)

We report on a new light-actuated digital microfluidics device which is capable of using on demand, `virtual' electrodes formed by a data projector to enable large-scale, parallel manipulation of arbitrarily sized droplets. The device features a thin, high-quality Al <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> film deposited via atomic layer deposition (ALD) which allows aggressive scaling of the dielectric thickness, while maintaining high device reliability. We demonstrate the splitting, merging and parallel manipulation of droplets at high actuation speeds (2 cm/s). Due to the thin ALD dielectric layer, this high actuation speed is achieved at 85x lower optical power and 5x lower voltage than our previous device.
Bacillus shacheensis sp. nov., a moderately halophilic bacterium isolated from a saline-alkali soil (2014)

A moderately halophilic bacterium, strain HNA-14(T), was isolated from a saline-alkali soil sample collected in Shache County, Xinjiang Province. On the basis of the polyphasic taxonomic data, the isolate was considered to be a member of the genus Bacillus. The organism grew optimally at 30 °C and pH 8.0. It was moderately halophilic and its optimum growth occurred at 5-10% NaCl. The diamino acid found in the cell-wall peptidoglycan was meso-diaminopimelic acid and the predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C15:0 and iso-C15:0 and the polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and two unknown phospholipids. The G+C content of the genomic DNA was 48.6 mol%. Strain HNA-14(T) exhibited a low 16S rRNA gene sequence similarity of 96% with its nearest neighbors [Bacillus clausii KSM-K16 (96.5%), Bacillus xiaoxiensis DSM 21943(T)(96.2%), Bacillus clausii DSM 8716(T) (96.1%), Bacillus patagoniensis PAT05(T) (96.1%), Bacillus lehensis MLB-2(T) (96.0%), Bacillus oshimensis K11(T) (95.9%) and Bacillus hunanensis DSM 23008(T) (95.8%)] and the phenotypic characteristics indicate that strain HNA-14(T) can be distinguished from them. Therefore, a novel species of the genus Bacillus, Bacillus shacheensis sp. nov. (type strain, HNA-14(T) = KCTC 33145 = DSM 26902) is proposed.
On computing the discrete Fourier transform (1978)

A new algorithm for computing the Discrete Fourier Transform is described. The algorithm is based on a recent result in complexity theory which enables us to derive efficient algorithms for convolution. These algorithms are then used to obtain the new Discrete Fourier Transform algorithm.
Rituximab Combined to ACVBP (R-ACVBP) as a New Inductive Treatment Followed by High-Dose Consolidative Autotransplantation (HDC) for Poor Risk Diffuse Large B-Cell Lymphoma (DLBCL) in First-Line. Preliminary Results on 119 Patients of a GELA Phase II Study. (2006)

Abstract ACVBP induction regimen followed by HDC provides a better event-free survival (EFS) and overall survival (OS) as compared to a conventional consolidative treatment in patients (pts) with aggressive non Hodgkin’s lymphoma presenting with 2 or 3 adverse age-adjusted International-Prognostic-Index (aa-IPI) who first reached complete remission. However, complete response rate (CR +CRu) after ACVBP is not superior to 65% (ASH 2005, 677a). Besides, it is established that Rituximab (R) combined with CHOP improves complete remission rate and OS in elderly pts. The objective of the study was to see if combining R (375 mg/m2) to ACVBP (Doxorubicin 75 mg/m2 d1, Cyclophosphamide 1,200 mg/m2 d1, Vindesine 2 mg/m2 and Bleomycin 10 mg d1 and d5, prednisone 60 mg/m2 d1-d5) translates into an improvement of response rate and also EFS in pts under 60y with DLBCL and aaIPI 2 or 3. Four cycles of R-ACVBP were delivered every 15 days supported by filgrastim 5 μg/kg (d6 to d13) or pegfilgrastim (6 mg at day 3). Responding pts received a consolidative BEAM and peripheral blood stem cell rescue. From 01/2004 to 12/2005, 119 DLCBL pts were enrolled. Median age was 49 years (range: 19–60), 18% with aa-IPI 3, 22% with bone marrow involvement, 96% with LDH&gt; 1N and 88% with extranodal sites&gt;1. 59 pts received filgrastim and 60 pegfilgrastim. Based on International Workshop Criteria, CR+CRu rate after induction treatment was 63%, PR rate 25%, stable disease 3% and progressive disease 1%. Deaths without progression occurred in 3% of the pts, and 6% of them could not be assessed (treatment was stopped because of toxic effects or major protocol violation). Hematologic toxicity was similar to that observed in previous GELA trials using ACVBP. Collection failure after the 3rd and/or 4th R-ACVBP cycle was observed in 15 pts (13%), 4 receiving filgrastim and 11 pegfilgrastim (7 of them being further collected with filgrastim). Among the 105 responding pts, 90 received HDC, 15 pts did not (physician’s decision for 4 PET-positive pts after 4 R-ACVBP, 8 collection failures, 2 pts because of a poor performance status after induction phase and one due to sudden death). Three patients died without progression during the HDC procedure. At the end of treatment, 81 pts (68%) were considered in complete remission, 14% in PR and 6% progressed. With a median follow-up of 15 months, two-year EFS was 72% ( CI 62–68%), OS was 79% ( CI 69–86%). We conclude that R-ACVBP induction regimen is feasible and safe on such high risk pts but it does not increase the CR rate. EFS seems encouraging; a longer follow-up is needed to see whether the addition of rituximab contributes to decrease the incidence of relapse.
High-grade sarcomas mimicking traumatic intramuscular hematomas: a report of three cases. (2004)

We reported on three patients with high-grade soft-tissue sarcomas mimicking traumatic intramuscular hematomas. Patients had an episode of trauma to the extremity, and after initial clinical and imaging evaluations they were considered to have muscular hematomas. The lesions increased in size over time, leading to further evaluations that demonstrated the actual diagnosis. We conducted a retrospective review of the clinical findings, magnetic resonance images, and computed tomography scans to assess characteristics that will help in the differential diagnosis. We conclude that intramuscular hematomas following trauma should be approached with a high degree of clinical suspicion. MRI analysis can be used as an important diagnostic tool, but the results must be seen in the context of the clinical history. MRI is not sensitive or specific enough to rule out malignancy. The diagnosis of a high-grade sarcoma must be considered in these patients and any doubt should be resolved with a biopsy.

Measurement of the nonlinear refractive index in optical fiber by the cross-phase-modulation method with depolarized pump light (1995)

Depolarized pump light is used in measurements of the nonlinear refractive index, n2, in optical fiber by the cross-phase-modulation method. High measurement repeatability within ±1% is obtained by this method. The nonlinear refractive index is determined for dispersion-shifted fiber, standard single-mode fiber, pure silica-core single-mode fiber, and dispersion-compensating fiber as 3.35 × 10−20, 2.96 × 10−20, 2.79 × 10−20, and 4.44 × 10−20 m2/W, respectively, at 1.55 μm. This shows that the nonlinear refractive indices of the optical fibers differ greatly according to glass composition.
The accuracy of retrospectively measured range of motion in knee arthroplasty. (2012)

In retrospective studies the range of motion of the knee is gathered from existing clinical notes or databases. This study aims to assess the validity of this retrospective data. The range of motion of 48 patients was assessed using a goniometer and compared to that entered in the patient notes by the examiner during a routine clinical examination, without the examiner being aware. The range of motion of a further 20 patients was subsequently assessed and compared to the findings of the same clinical examiners but this time with the examiner being aware. When the examiner was unaware of the study, the accuracy of the measured range of motion was clinically unacceptable. When the examiner was aware of this study, the accuracy of the measure was much improved. The patient's body mass index can affect the accuracy of visual estimation. Visual estimation of range of motion can be accurate and correlates well to that measured by a goniometer if the examiner attempts to be accurate. However range of motion that is routinely measured in a clinical setting and entered into the patient notes is not accurate and should not be relied on in future research.
ACTION OF INSULIN ON SUGAR PERMEABILITY IN RAT DIAPHRAGM MUSCLE (1959)

Insulin action upon sugar permeability has been examined in rat diaphragm muscle prepared so that the fibers are either intact or cut. In intact preparations, sucrose and mannitol are largely excluded from the intracellular water while D-galactose, D-xylose, and L-xylose equilibrate in a small fraction of the total cell water; the availability of cell water for D-galactose, D-xylose, and L-xylose is increased by insulin. In cut preparations, in which the cell membrane is not intact, all the sugars studied penetrate into the cell, but intracellular water is not uniformly available for subsequent permeation. Sucrose distributes in a volume of about 40 to 45 per cent of the available cell water; D-xylose, D-galactose, L-xylose, and mannitol are distributed in all or most of the cell water, but these sugars diffuse at different rates. In cut preparations insulin increases the rate of equilibration of D-galactose and D-xylose without significant effect on the other sugars studied; insulin also exerts a "directive" influence on glycogen synthesis from glucose, which cannot be explained solely in terms of accelerated sugar penetration. The significance of these observations in elucidating the locus of insulin action is discussed.
Dissipation of the herbicide active ingredient glyphosate in natural water samples in the presence of biofilms (2017)

Dissipation of the herbicide active ingredient glyphosate was investigated in natural waters. To assess combined effects, glyphosate was applied in its pure form (glyphosate isopropylammonium salt) and in preparation Roundup Classic® formulated with polyethoxylated tallowamines (POEA). Standing and running surface water samples originated from Lake Balaton and River Danube between early May and mid-June of 2015. The kinetics of dissipation of glyphosate, measured by high-performance liquid chromatography combined with UV-VIS absorbance detection or tandem mass spectrometry, was investigated under laboratory conditions in aquaria with or without the presence of biofilms. The quantity and the biofilm structure of algal biomass were determined by in vivo fluorimetry and scanning electron microscopy. The presence of POEA affected the dissipation of glyphosate, and dissipation profiles differed in the investigated natural waters. Significantly higher initial concentrations of glyphosate were measured in River Danube for treatment with formulated glyphosate (101.4 ± 6.2 µg L−1), than with glyphosate alone (79.9 ± 6.6 µg L−1), and dissipation to a residual level (57.6 ± 1.4 µg L−1) consequently took longer (approximately by 1 day). Degradation of glyphosate from the initial level (91.24 ± 5.9 µg L−1) in Lake Balaton was not detected. Phytotoxic effects of glyphosate, particularly if enhanced by a formulant on algal biomass, were observed. Thus, 5–18% and 11–33% of algal biomass reduction was determined in River Danube upon treatments with glyphosate and Roundup Classic®, respectively. Corresponding biomass decreases in Lake Balaton were 1.3–13% and 9–14%, respectively, accompanied by an overall decay in the algal biofilms. In River Danube, treatments resulted in the occurrence of 1.4–5.8% of green algae in the algal biomass in 28 days, while green algae were not detected in the untreated control. The results indicate that glyphosate is capable of modifying the structure of the algal community and to induce increased secretion of extracellular polymeric substances matrix in the biofilms assessed.
Enhancement of ultraviolet light responsivity of a pentacene phototransistor by introducing photoactive molecules into a gate dielectric (2014)

We demonstrated a new approach to fabricate an ultraviolet (UV) photodetector with a pentacene transistor structure where photoactive molecules of 6-[4′-( N , N -diphenylamino)phenyl]-3-ethoxycarbonylcoumarin (DPA-CM) were introduced into a poly(methyl methacrylate) (PMMA) gate dielectric. DPA-CM molecules strongly absorb UV light and form stable charge-separation states. When a negative gate voltage was scanned to a gate electrode of the transistor, the charge-separation states of DPA-CM molecules were converted into free electrons and holes. The free electrons traversed and subsequently reached an interface of the PMMA:DPA-CM layer and a polystyrene buffer layer, inducing accumulation of additional holes in a pentacene channel. Therefore, under 2.54 mW/cm 2 of 365 nm UV irradiation, a marked increase in drain current by 6.1 × 10 2 times were obtained from the transistor. Moreover, the phototransistor exhibited a high light responsivity of 0.12 A/W which is about one order of magnitude larger than that of a conventional pentacene phototransistor [Lucas et al., Thin Solid Films 517 , 280 (2009)]. This result will be useful for manufacturing of a high-performance UV photodetector.
