Modern to millennium-old greenhouse gases emitted from freshwater ecosystems of the eastern Canadian Arctic (2015)

Abstract. Ponds and lakes are widespread across the rapidly changing permafrost environments. Aquatic systems play an important role in global biogeochemical cycles, especially in greenhouse gas (GHG) exchanges between terrestrial systems and the atmosphere. The source, speciation and emission of carbon released from permafrost landscapes are strongly influenced by local specific conditions rather than general environmental setting. This study reports on GHG ages and emission rates from aquatic systems on Bylot Island in the eastern Canadian Arctic. Dissolved and ebullition gas samples were collected during the summer season from different types of water bodies located in a highly dynamic periglacial valley: polygonal ponds, collapsed ice-wedge trough ponds, and larger lakes overlying unfrozen soils (talik). The results showed strikingly different ages and fluxes depending on aquatic system types. Polygonal ponds were net sinks of dissolved CO2, but variable sources of dissolved CH4. They presented the highest ebullition fluxes, one or two orders of magnitude higher than from other ponds and lakes. Trough ponds appeared as substantial GHG sources, especially when their edges were actively eroding. Both types of ponds produced modern to hundreds of years old (&lt;550 yr BP) GHG, even if trough ponds could contain much older carbon (&gt;2000 yr BP) derived from freshly eroded peat. Lakes had small dissolved and ebullition fluxes, however they released much older GHG, including millennium-old CH4 (up to 3500 yr BP) sampled from lake central areas. Acetoclastic methanogenesis dominated at all study sites and there was minimal, if any, methane oxidation in gas emitted through ebullition. These findings provide new insights on the variable role of permafrost aquatic systems as a positive feedback mechanism on climate.
Signature Killer: Caravaggio and the Poetics of Blood (2012)

Blood is one of the most powerful metaphors in art and literature. In his 1608 altarpiece for the Knights of Malta, The Beheading of Saint John the Baptist, Caravaggio signed his name “in the blood” of the executed saint. This witty and violent gesture, fruit of the predicament that had brought him to the island—murder, exile, and the chance for redemption—engages in a number of personal and political discourses, some inspired by his honorary knighthood. The signature, which builds on self-fashioning themes explored in Caravaggio's earlier paintings, also makes a bold contribution to the poetics of concettismo.
Antazoline for rapid termination of atrial fibrillation during ablation of accessory pathways (2013)

Antazoline safely and rapidly converts AF into sinus rhythm during ablation of AP. The drug does not block AP completely, enabling continuation of ablation. The drug converting AF into more organized atrial activity (atrial flutter/tachycardia) before sinus rhythm resumption.
Functional Evaluation in the Rat Sciatic Nerve Defect Model (2013)

Toe contractures occurred more frequently in rats with better nerve recovery, and interfered with evaluation of the motor recovery using the sciatic functional index method. Ankle angle in toe-off phase measured from video gait analysis is a useful parameter that reflects functional recovery of the muscle force.
Electrical Conductive Corundum-Structured α-Ga2O3Thin Films on Sapphire with Tin-Doping Grown by Spray-Assisted Mist Chemical Vapor Deposition (2012)

We report the fabrication of electrical conductive tin-doped α-Ga2O3 thin films on c-plane sapphire substrates. The mist chemical vapor deposition method brought tin-doped α-Ga2O3 thin films with high crystallinity without noticeable other phases, as highlighted by the full-width of X-ray diffraction ω-scan rocking curves as small as 40 arcsec, for the tin atomic density in the film upto ∼1020 cm-3. The resistivity decreased by more doping of tin, and the α-Ga2O3 thin film with minimum resistivity exhibited n-type conductivity with the Hall mobility of 2.8 cm2 V-1 s-1 and the carrier density of 2.7 ×1019 cm-3.
Enhanced growth rates of nanodroplets in the free molecular regime: The role of long-range interactions (2016)

Recently, Pathak et al. Citation(2013) conducted a series of non-isothermal D2O nanodroplet growth studies in the free molecular regime. They found that under highly non-equilibrium conditions, the condensation (qc) and evaporation coefficients (qe) can differ from each other and from the expected value of 1. Here, we confirm these observations by analyzing comparable experiments using n-propanol. We show that the best agreement with the non-isothermal Hertz–Knudsen growth law corresponds to setting (qc, qe) = (1, 0.6) or (qc, qe) = (1.3, 1). The approach of retarded evaporation yields values close to those observed by Pathak et al. for D2O, but is difficult to justify theoretically. Enhancing the condensation coefficient is consistent with long-range attractive interactions between the vapor molecules and droplets in the nanometer size range.© 2016 American Association for Aerosol Research
Investigation of effects of fucoidan polysaccharides extracted from twospecies of Padina on the wound-healing process in the rat (2017)

Seaweeds contains different types of polysaccharides with high abilities. The aim of this study was to determine the potential of fucoidan polysaccharides for wound-healing properties. Fucoidans of two species of Padina (P. tetrastromatica and P. boergesenii), collected from the Persian Gulf northern coastal area, were extracted and analyzed using high-performance anion-exchange chromatography. Purified fucoidans were used to prepare a 2% topical ointment. Under aseptic conditions, two identical paravertebral full-thickness skin wounds (either by burn or excision) were made in 40 anesthetized male rats allocated into 4 groups. Either fucoidan ointments or the vehicle (ointment base) were applied to rats' wounds twice daily for 14 days. In addition to the examination of wound area reduction (days 3, 7, 10, and 14) and histopathological assays (days 7 and 10), tissue specimens were taken to the laboratory. Fucoidans obtained from both seaweeds induced significant wound area reduction compared to the vehicle at some time points after treatment. Histopathological examinations showed improvement in some healing signs including angiogenesis, collagen fiber formation, and epidermis formation. In conclusion, both species of Padina have significant wound-healing effects and fucoidan polysaccharides are the active constituents for this healing property. However, fucoidan obtained from P. boergesenii showed superior effects in this regard.
Safety of datalog queries over infinite databases (1989)

A query is safe with respect to a set of constraints if for every database that satisfies the constraints the query is guaranteed to yield a finite set of answers. We study here the safety problem for Datalog programs with respect to finiteness constraints. We show that safety can be viewed as a combination of two properties: weak safety, which guarantees the finiteness of intermediate answers, and termination, which guarantees the finiteness of the evaluation. We prove that while weak safety is decidable, termination is not. We then consider monadic programs, i.e., programs in which all intensional predicates are monadic, and show that safety is decidable in polynomial time for monadic programs. While we do not settle the safety problem, we show that a closely related problem, the decision problem for safety with respect to functional dependencies, is undecidable even for monadic programs.
The Bcl‐2 family member Bfl‐1/A1 is strongly repressed in normal and malignant plasma cells but is a potent anti‐apoptotic factor for myeloma cells (2004)

Terminal B-cell differentiation is a multi-step process, from short-lived plasmablasts to mature long-lived plasma cells (PC). The anti-apoptotic Bcl-2 family member Bfl-1/A1 plays a critical role in the survival of mature B cells. However, its potential involvement at the later stages of B-cell development remains highly controversial. Our aim was thus to clarify the place of Bfl-1/A1 in the biology of normal PC and in the pathogenesis of multiple myeloma (MM), the major PC dyscrasia. Using gene expression profiling and quantifiable reverse transcription polymerase chain reaction experiments, we found a similar down-regulation of Bfl-1/A1 in both normal immature plasmablasts and mature PC when compared with B cells. In myeloma cells, the level of Bfl-1/A1 was low and Bfl-1/A1 was not a nuclear factor kappaB-inducible gene. Collectively, these data demonstrate that Bfl-1/A1 is not involved in the prolonged survival of normal mature PC, and that Bfl-1/A1 deregulation is not a common oncogenic event in MM. However, overexpression of Bfl-1/A1 by retroviral transduction promoted autonomous survival of an interleukin-6-dependent myeloma cell line and rendered it less sensitive to dexamethasone. Thus, Bfl-1/A1 transduction could be an interesting tool to obtain myeloma cell lines from primary samples and to favour the in vitro generation of antibody-secreting, long-lived normal PC.
Plate flat heat pipe and liquid-cooled coupled multistage heat dissipation system of Li-ion battery (2018)

A thermal management system with the capability of achieving excellent heat dissipation is essential to the development of battery pack for transportation devices. To meet the temperature uniformity requirements of the battery pack, the plate flat heat pipe and liquid-cooled coupled multistage heat dissipation system had been introduced. In this article, the research status of thermal management systems in battery pack was introduced. And the heat generation and heating power of the Li-ion cell were studied. Then, the structure model of plate flat heat pipe system was proposed. Finally, the enhanced heat conduction effect of the thermal management system proposed in this article was comprehensively analyzed. Through the analysis of the results, in high discharge rates, the thermal management system proposed in this article could meet the temperature uniformity requirements of battery pack; also, the internal difference would reduce by 30.20%.
Imaging of Turbid Media with a Spatial Filter (2022)

A buried object inside a turbid medium was imaged using a continuous-wave laser of 5-mW output power and a spatial filter. The spatial filter consists of a lens of 4-cm focal length and a pinhole of 10-μm diameter. A lock-in amplifier was used to reduce the noise. An absorbing rod of 2-mm diameter was buried in the center of a 5-cm thick cuvette filled with polystyrene spheres solution. The object was detected with a contrast of 99% when the turbid medium was 20 mean free path thick, and 10% when 30 mean free path thick.
Is protein‐deficient diabetes mellitus a pancreatitis? (1999)

The significance of these changes is not clear, but they may represent an ongoing pancreatic disease and may, indeed, be the earliest changes of chronic pancreatitis.
Random noise in switching DC-DC converter: verification and analysis (2003)

System parameter variations due to random noise may significantly alter predicted performance of a power converter. In this paper, an experimental setup to verify the existence of noise and its statistical properties in a switching pulse-width modulated (PWM) DC-DC converter is presented. We present a converter model that captures the effect of these inherent random noises on the overall behavior of a practical converter. We also propose a performance index quantifying the converter performance under the influence of random noise.
Basic Function and Applications of Polyglycerol Dendrimers (2017)

ポリグリセロールデンドリマー（PGD）やハイパーブランチポリグリセロール（HPG）は，親水性の特徴を示すのみならず，水中では弱い疎水性の特徴を示す。この弱い疎水性環境とPGD，HPDの枝分かれ度の違いに起因するナノ空間によって，様々なサイズの塩基性低分子化合物を認識するホスト分子として機能することが明らかになってきた。一方，親水性の特徴から，血液からの診断目的で使用されるバイオセンサ表面にPGDやGDを固定化すると，血液中のタンパク質の吸着を抑制する効果が期待されるが，疎水場の提供によってむしろ抗体を吸着する選択的なタンパク質吸着制御の可能性が示された。PGD及びHPDは，枝分かれ度とナノ空間の違いに起因する分子間相互作用に選択性を付与するユニークな特徴が期待される。
Critical Assessment of Small Molecule Identification 2016: automated methods (2017)

The improvement in (semi-)automated fragmentation methods for small molecule identification has been substantial. The achieved high rates of correct candidates in the Top 1 and Top 10, despite large candidate numbers, open up great possibilities for high-throughput annotation of untargeted analysis for "known unknowns". As more high quality training data becomes available, the improvements in machine learning methods will likely continue, but the alternative approaches still provide valuable complementary information. Improved integration of experimental context will also improve identification success further for "real life" annotations. The true "unknown unknowns" remain to be evaluated in future CASMI contests.

Similarity indexing with the SS-tree (2002)

Efficient indexing of high dimensional feature vectors is important to allow visual information systems and a number other applications to scale up to large databases. We define this problem as "similarity indexing" and describe the fundamental types of "similarity queries" that we believe should be supported. We also propose a new dynamic structure for similarity indexing called the similarity search tree or SS-tree. In nearly every test we performed on high dimensional data, we found that this structure performed better than the R*-tree. Our tests also show that the SS-tree is much better suited for approximate queries than the R*-tree.
Total Thyroidectomy vs Thyroid Lobectomy for Localized Papillary Thyroid Cancer in Children: A Propensity-Matched Survival Analysis (2021)

This study suggests that the extent of thyroidectomy does not influence survival for pediatric patients with early-stage PTC and that TL might be adequate in this patient population.
The effect of naloxone‐3‐glucuronide on colonic transit time in healthy men after acute morphine administration: a placebo‐controlled double‐blinded crossover preclinical volunteer study (2008)

Orally administered NX3G is able to reverse the morphine-induced delay of CTT in humans without being detected in peripheral blood samples. Therefore, NX3G may improve symptoms of constipation in-patients using opioid medication without affecting opioid-analgesic effects.
An Investigation of Catalogued Product Development Information at a Major Consumer Products Company (2001)

Abstract A study of product development practices at a major consumer product manufacturer, referred to as Company X, was undertaken to compare its methods to an earlier effort in modeling the flow of information in product design, referred to as the Design Information Flow Model. The model considers the recognized need in industry for the seamless capture, storage, and retrieval of design information. The research at Company X focused on the front end of product design, that is, the conceptual phase. It was learned that design, as defined by the Information Flow Model, is well represented at the front end of the company’s design process. However, this validation effort succeeded in uncovering certain voids, particularly in later states of the model. It was also learned that product documentation quality and quantity at Company X vary from project to project, indicating an important aspect to consider in our efforts to enhance computer-aided product design is the user.
Advanced display technologies: An Investigation of the emerging and developing technologies related to the generation beyond print-on-paper (2003)

The purpose of this paper is to present information about new display technologies that are competing with print. Display technology continues to mature, as in the case of full-color OLED, which has been incorporated into its first consumer product, The Kodak EasyShare LS 633 digital camera. Digital ink pioneer E Ink, through its partnership with Philips Electronics, will introduce its first commercial product in early 2004. Gyricon Media, the inventor of the electronic paper category, has opened its first manufacturing plant. In addition, new flexible display technologies have been introduced, such as SiPix Microcup, and the electronic display form-factor has been scaled up considerably by companies such as Magink and NOVUS. These companies are poised to produce large-format electronic displays that rival the size of traditional 30-sheet billboards. Developments continue to evolve in displays of all sizes, from those the size of cell phone to those on the sides of buildings.
A new intravascular membrane oxygenator to augment blood gas transfer in patients with acute respiratory failure. (1991)

The IVOX (intravascular oxygenator) is an intracorporeal, hollow-fibre membrane oxygenator and carbon dioxide (CO2) removal device. The IVOX is surgically placed into the vena cava via a femoral or jugular venotomy. Oxygen (O2) is pulled through the hollow fibers by a vacuum pump controlled by a flow meter. There is no extracorporeal circulation of blood. Gas exchange occurs as the patient's blood flows over several hundred hollow fibers. Inlet and outlet gas conduits exit a small skin incision for inflow of O2 and outflow of CO2. Studies in sheep and humans show that the IVOX can support approximately 30% of gas exchange requirements. The position of the IVOX in the vena cava does not affect hemodynamics or cause thromboembolic complications. It can remain in place for up to 22 days without affecting hematologic or blood chemistry parameters. The IVOX is currently undergoing clinical trials at selected medical centers in patients with acute respiratory failure.
Design Method of Vibrationally Optimum Tooth Flank Form for Involute Helical Gears with Scattering in Pressure Angle and Helix Angle Deviation. (2000)

The detail in geometrical shape of each tooth flank of mass-production gears is usually not the same. Even a slight deviation of tooth flank form of several micrometers has a big influence on the running vibration/noise of the transmisstion gear box. The influence of the scattering in tooth flank form on the vibrational characteristics of gears must therefore be taken into consideration at the design stage to achieve low vibration gears. In this report, the influence of typical types of scattering, i.e.inpressure angle deviation and helix angle deviation, on the vibrational excitation is clarified in terms of the relationship between vibrational excitation and actual contact ratio. Those types of scattering decrease the actual contact ratio of a gear pair from that value of the tooth flank form designed on a draft. Gears with scattering in tooth flank form can run silenter, when some less amount of tooth flank form modification than the optimum one for gears without the scattering is given. The design algorithm for optimum modification of tooth flank form with scattering is proposed.

Solution structure of a pentachromium(ii) single molecule magnet from DFT calculations, isotopic labelling and multinuclear NMR spectroscopy (2017)

The structure of pentachromium(ii) extended metal atom chain [Cr<sub>5</sub>(tpda)<sub>4</sub>Cl<sub>2</sub>] (2), which behaves as a single molecule magnet at low temperature, was investigated by Density Functional Theory (DFT) calculations and spectroscopic studies without the constraints of a crystal lattice (H<sub>2</sub>tpda = N<sup>2</sup>,N<sup>6</sup>-bis(pyridin-2-yl)pyridine-2,6-diamine). DFT studies both in the gas phase and including CH<sub>2</sub>Cl<sub>2</sub> solvent effects indicate that an unsymmetric structure (C<sub>4</sub> point group), with pairs of formally quadruply-bonded metal ions and one terminal metal center, is slightly more stable (2.9 and 3.9 kcal mol<sup>-1</sup>) than a symmetric structure (D<sub>4</sub> point group). Isotopically-labelled samples (2-d<sub>8</sub> and 2-d<sub>16</sub>) have then been prepared to aid in molecular symmetry determination by combined <sup>1</sup>H and <sup>2</sup>H NMR studies in dichloromethane solution. The spectra are strongly suggestive of a symmetric (D<sub>4</sub>) framework, indicating fast shuttling between the two unsymmetric forms over the timescale of NMR experiments. Procedures for a high-yield Pd-free synthesis of H<sub>2</sub>tpda and for site-selective post-synthetic H/D exchange of aromatic H<sub>2</sub>tpda hydrogens are also reported.
Thaxtomin A affects CESA-complex density, expression of cell wall genes, cell wall composition, and causes ectopic lignification in Arabidopsis thaliana seedlings (2009)

Thaxtomin A, a phytotoxin produced by Streptomyces eubacteria, is suspected to act as a natural cellulose synthesis inhibitor. This view is confirmed by the results obtained from new chemical, molecular, and microscopic analyses of Arabidopsis thaliana seedlings treated with thaxtomin A. Cell wall analysis shows that thaxtomin A reduces crystalline cellulose, and increases pectins and hemicellulose in the cell wall. Treatment with thaxtomin A also changes the expression of genes involved in primary and secondary cellulose synthesis as well as genes associated with pectin metabolism and cell wall remodelling, in a manner nearly identical to isoxaben. In addition, it induces the expression of several defence-related genes and leads to callose deposition. Defects in cellulose synthesis cause ectopic lignification phenotypes in A. thaliana, and it is shown that lignification is also triggered by thaxtomin A, although in a pattern different from isoxaben. Spinning disc confocal microscopy further reveals that thaxtomin A depletes cellulose synthase complexes from the plasma membrane and results in the accumulation of these particles in a small microtubule-associated compartment. The results provide new and clear evidence for thaxtomin A having a strong impact on cellulose synthesis, thus suggesting that this is its primary mode of action.
Influence of Gd(3+)Doping on Properties of NaY(MoO(4))(2):Eu(3+) Phosphors (2011)

Eu(3+)-doped NaY(MoO(4))(2) and Na(Y, Gd)(MoO(4))(2) phosphors were prepared via microemulsion-hydrothermal method. X-ray diffraction (XRD), scanning electron microscopy (SEM) and fluorescence spectroscopy were used to characterize the samples. The XRD of as-prepared samples were in agreement with the PDF # 82-2369 of NaY(MoO(4))(2). SEM images showed that the as-prepared particles had a diameter size ranging from 0.5 to 0.8 mu m. The critical activator molar concentration (Eu(3+)) in NaY(MoO(4))(2) : Eu(3+) was 4%, and the luminescent intensity of Na(Y, Gd)(MoO(4))(2) : 4%Eu(3+)was maximum when Y : Gd molar ratio at 0.5 : 0.5. Excited by 276, 395 and 465 nm, Na(Y(0.48), Gd(0.48))(MoO(4))(2) : 4%Eu(3+)exhibited pale pink, yellow and orange-red respectively. The sample of Na(Y, Gd)(MoO(4))(2) : Eu(3+) could become a valuable luminescent material for white LED.
