Phosphinic Acid Based Linkers: Building Blocks in Metal–Organic Framework Chemistry (2018)

Abstract Metal–organic frameworks (MOFs) are a chemically and topologically diverse family of materials composed of inorganic nodes and organic linkers bound together by coordination bonds. Presented here are two significant innovations in this field. The first is the use of a new coordination group, phenylene‐1,4‐bis(methylphosphinic acid) (PBPA), a phosphinic acid analogue of the commonly used terephtalic acid. Use of this new linker group leads to the formation of a hydrothermally stable and permanently porous MOF structure. The second innovation is the application of electron‐diffraction tomography, coupled with dynamic refinement of the EDT data, to the elucidation of the structure of the new material, including the localization of hydrogen atoms.
Holographic data storage with arbitrarily misaligned data pages (2002)

An improved postprocessing algorithm that can compensate for arbitrary misregistrations between a detector array and the coherent image of a pixelated two-dimensional data page is described. Previously [Opt. Lett. 26, 542 (2001)], an algorithm was reported in which both linear and quadratic interpixel cross-talk contributions are reallocated to the appropriate neighboring pixels. However, page misalignments close to +/-0.5 pixels could not be corrected to an acceptable bit-error rate because of propagation in the iterative procedure. An improved algorithm is reported in which an intentional magnification error is introduced optically and then corrected during postprocessing. Experimental results from a pixel-matched megapel volume holographic system are presented, showing that the dependence of bit-error rate on transverse detector alignment is entirely removed. This improved procedure can completely bypass constraints on page registration, optical distortion, and material shrinkage that currently hamper page-oriented holographic storage systems.
HuR Is Required for IL-17–Induced Act1-Mediated CXCL1 and CXCL5 mRNA Stabilization (2013)

IL-17, a major inflammatory cytokine plays a critical role in the pathogenesis of many autoimmune inflammatory diseases. In this study, we report a new function of RNA-binding protein HuR in IL-17-induced Act1-mediated chemokine mRNA stabilization. HuR deficiency markedly reduced IL-17-induced chemokine expression due to increased mRNA decay. Act1-mediated HuR polyubiquitination was required for the binding of HuR to CXCL1 mRNA, leading to mRNA stabilization. Although IL-17 induced the coshift of Act1 and HuR to the polysomal fractions in a sucrose gradient, HuR deficiency reduced the ratio of translation-active/translation-inactive IL-17-induced chemokine mRNAs. Furthermore, HuR deletion in distal lung epithelium attenuated IL-17-induced neutrophilia. In summary, HuR functions to couple receptor-proximal signaling to posttranscriptional machinery, contributing to IL-17-induced inflammation.
Performance of Turbo Coding With Improved Interference Estimation on the CDMA Space Time Transmit Diversity Forward Link (2006)

This paper proposes an approach to improve turbo code performance on the space time transmit diversity (STTD) code-division multiple-access (CDMA) forward link through better estimation of the channel state information (CSI) required by the mobile turbo decoder. An improved CSI estimation scheme that accounts for the unique nature of CDMA STTD intracell interference is presented. It is compared to a standard CSI estimation scheme that assumes all STTD interference and noise can be represented as additive white Gaussian noise at the mobile receiver input. An STTD CDMA forward link simulation shows that link performance is significantly improved when the mobile turbo decoder uses the more accurate CSI provided by improved estimation. However, the degree of improvement depends on the turbo decoding algorithm, mobile velocity, and whether the base station is using STTD or single-antenna transmission
Dynamic scheduling of network updates (Extended version) (2014)

We present Dionysus, a system for fast, consistent network updates in software-defined networks. Dionysus encodes as a graph the consistency-related dependencies among updates at individual switches, and it then dynamically schedules these updates based on runtime differences in the update speeds of different switches. This dynamic scheduling is the key to its speed; prior update methods are slow because they pre-determine a schedule, which does not adapt to runtime conditions. Testbed experiments and data-driven simulations show that Dionysus improves the median update speed by 53–88% in both wide area and data center networks compared to prior methods.
Ceramics in the NbB{sub 2}-CrB{sub 2} (1995)

Phase equilibria and properties of ceramics in the NbB{sub 2}-CrB{sub 2} system were studied. Continuous solid solutions were found showing high activation energy (96 kcal/mol) of formation which is due to large disparity of atomic radii between Cr and Nb. Pure NbB{sub 2} and CrB{sub 2} ceramics were prepared by hot pressing at 2,100 and 1,800 C, respectively, at 20 MPa for 0.5 hour. Both materials exhibited closed porosity which was eliminated by the addition of Al{sub 2}O{sub 3} and SiC. Thermogravimetric studies showed different mechanisms of oxidation of the diborides. The presence of Al{sub 2}O{sub 3} and SiC improved the oxidation resistance, hardness, and fracture toughness of CrB{sub 2} ceramics. The additives increased the hardness of NbB{sub 2} ceramics but did not significantly affect their toughness.
Club Shaft Weight in Putting Accuracy and Perception of Swing Parameters in Golf Putting (2007)

This study assessed how shaft weight influenced golf putting accuracy and subjective perception of swing parameters. Three putters of different shaft weight (100, 420, and 610 gm) were tested by 24 club players. Distance and deviation in direction were measured, and subjective ratings of the putters recorded. Subjects hit the ball further with lighter shafts. The mean distance hit was 100.2, 99.3, and 98.1% of the target distance for the normal, medium, and heavy putter shafts, respectively. Subjectively, the medium heavy putter was rated best on "overall feeling" and it was also rated better than the normal on"feeling of stability in the downswing." The heaviest putter was rated as too heavy by 23 of 24 subjects. There were no significant differences between the putter clubs in distance and directional putting accuracy. The major findings are that the golfers putted 2.1% longer with the 100 gm shaft than with the 610 gm shaft and that the perception of overall feeling of the putter club was not related to performance.
Intraoperative measurement of cochlear microphonic (CM) caused by direct excitation of ossicles with transducer (2018)

Cochlear microphonic (CM) is known to faithfully correspond to the frequency and level of sound pressure applied to the cochlea. If the CM is measured and compared before and after the treatment during an otologic surgery, the improvement of hearing of patients can be evaluated, and the risk of reoperation can be decreased. However, in some operations the sound transmission mechanism of the middle ear is temporarily disabled, and sound pressure cannot be applied to the cochlea with a speaker. In this study, a system for measuring the CM during surgery was constructed. The system consists of a vibration probe, electrodes, amplifier, and controller. The ossicles are vibrated by the vibration probe instead of sound from speaker, and the CM signals generated by the vibration are measured. The CM amplitude increased in proportion to the input voltage to the vibrator in the vibration probe as is the case with sound stimulation. This result suggests that the intraoperative assessment of improvement of hearing is possible by using the vibration probe.
JPEG-matched MRC compression of compound documents (2002)

Mixed raster content (MRC) is an ITU document compression standard (T.44) specifying both a model for multilayer representation of a compound document, and a set of allowable standardized coders for the individual layers. The model requires decomposition of a document into two image layers and a binary mask layer, but the standard does not recommend any procedure for this task. For best compression results, the decomposition method should be optimized for the layer encoders. In this paper, a high performance MRC compound document codec is presented, where the layer decomposition scheme is matched to the JPEG encoder with arithmetic coding for the foreground and background image layers. JBIG is used to code the mask layer. Integrated noise removal routines enable handling of scanned documents along with electronic ones. Resolution scalable decoding features are also implemented. The page segmenter yields a segmentation mask, which serves to separate text and other features.
Optimisation of Screw Expanders for Power Recovery From Low Grade Heat Sources (2013)

To obtain the best power output in wet vapour plant used in low grade heat utilisation depends not only on the conflicting requirements of high heat recovery and high working fluid temperatures but also on the dryness fraction of the fluid entering the expander, the screw expander size, rotor profile and speed and built-in volume ratio. It is shown in this paper how the optimisation methods and associated numerical procedures can be used to obtain the best combination of the often conflicting requirements imposed upon the screw expander in order to achieve its target, the maximum power output for given flow of the heating medium and its inlet and outlet temperatures. Measurements are performed with an expander in a steam power plant to obtain experimental results to validate performance estimation used in the optimisation process.
Optimization of Ultrafast Chirped-Pulse Amplification with Large Nonlinearity (2006)

The mechanism of chirped-pulse amplification performance improvement with interplay of nonlinearity and third-order dispersion is successfully interpreted with a simple theoretical model. One can extract design parameters optimizing the output performance according to the model
A Physical and Mechanical Model Able to Predict the Stress Field in Wood over a Wide Range of Drying Conditions (2004)

Abstract Drying is an essential operation of the wood industry. Computational models of wood drying appeared several decades ago. They started with just mass transfer in one dimension. Nowadays, comprehensive models exist, that can deal with three dimensions and comprehensive physical and mechanical formulation. Provided a comprehensive approach is usual (species characterization, mathematical modeling, computational simulation, and model validation), the computational model is a tool that is now used not only to improve existing procedures but also to imagine and tune innovative processes. Two examples are proposed, that allows the importance of the mechanical characterization to be exhibited: –To take advantage of the viscoelastic behavior of wood, and its hydro-thermal activation, to reduce significantly the drying time with the same quality of the dried product.–To compare the efficiency of two different drying schedules with informative conclusions.

Kinect-Like Depth Data Compression (2013)

Unlike traditional RGB video, Kinect-like depth is characterized by its large variation range and instability. As a result, traditional video compression algorithms cannot be directly applied to Kinect-like depth compression with respect to coding efficiency. In this paper, we propose a lossy Kinect-like depth compression framework based on the existing codecs, aiming to enhance the coding efficiency while preserving the depth features for further applications. In the proposed framework, the Kinect-like depth is reformed first by divisive normalized bilateral filter (DNBL) to suppress the depth noises caused by disparity normalization, and then block-level depth padding is implemented for invalid depth region compensation in collaboration with mask coding to eliminate the sharp variation caused by depth measurement failures. Before the traditional video coding, the inter-frame correlation of reformed depth is explored by proposed 2D+T prediction, in which depth volume is developed to simulate 3D volume to generate pseudo 3D prediction reference for depth uniqueness detection. The unique depth region, called active region is fed into the video encoder for traditional intra and inter prediction with residual coding, while the inactive region is skipped during depth coding. The experimental results demonstrate that our compression scheme can save 55%-85% in terms of bit cost and reduce coding complexity by 20%-65% in comparison with the traditional video compression algorithms. The visual quality of the 3D reconstruction is also improved after employing our compression scheme.
Hypoxia, HIF-1, and the Pathophysiologi of Common Human Diseases (2006)

Hypoxia plays a fundamental role in the pathophysiology of common causes of mortality, including ischemic heart disease, stroke, cancer, chronic lung disease, and congestive heart failure. In these disease states, hypoxia induces changes in gene expression in target organs that either fail to result in adequate adaptation or directly contribute to disease pathogenesis. Hypoxia-inducible factor 1 (HIF-1) is a transcriptional activator that is expressed in response to cellular hypoxia and mediates multiple cellular and systemic homeostatic responses to hypoxia. Recent studies have provided evidence that important pathophysiological responses to hypoxia in pulmonary hypertension, myocardial ischemia, and cancer are mediated by HIF-1. Pharmacologic and gene therapy strategies designed to modulate HIF-1 activity may represent a novel and effective therapeutic approach to these common disorders.
Short rare MUC6 minisatellites-5 alleles influence susceptibility to gastric carcinoma by regulating gene (2010)

The human MUC6 gene, which is reported to be expressed in the stomach and gall bladder, is clustered on chromosome 11p15.5 with other secreted mucins. In this study, the genomic structure of MUC6 has been analyzed and five VNTR (minisatellites; MS1-MS5) were identified. These minisatellites were analyzed in genomic DNA extracted from 1,103 controls, 470 gastric cancer patients, and multigenerational families. Five novel minisatellites were found to be polymorphic and transmitted through meiosis by Mendelian inheritance in families. We evaluated allelic variation in these minisatellites to determine if such variation affected the susceptibility to gastric cancer. A significant association (odds ratio [OR]=7.08) between short rare MUC6-MS5 alleles and relative risks were observed for gastric cancer (95% confidence interval [CI], 1.43-35.19; P=0.005). To investigate the function of minisatellite alleles of MUC6-MS5, we examined the effects on gene expression from luciferase reporters when inserted with minisatellites. Interestingly, when the shortest allele (7TR) was inserted in the promoter, the expression level decreased over 20-fold (P<0.001) in normal and cancer cell lines. Furthermore, the cancer-specific rare allele (TR8) also showed decreased expression levels in cancer cells. Therefore, we suggest that the short rare MUC6-MS5 alleles may be related to cancer development by the regulation of MUC6 expression.
Conversion of methane to ethylene (1997)

A lithium aluminate – MgO catalyst has been found to convert methane to ethylene with a high selectivity. The rate of conversion increased when a MoO 3 co-catalyst was used to remove the poisoning products. It is shown that for optimum conversion and selectivity to ethylene, the oxygen pressure should be at an intermediate value, high enough to provide active sites but low enough to avoid ethylene oxidation. Thus the oxygen should be "bled-in" along the catalyst bed. In demonstration of these concepts we have shown a 28.6% CH 4 conversion with 63.2% ethylene selectivity and 9.8% ethane, producing a C 2 yield of about 21.4%. Keywords: methane oxidation, methane conversion, ethylene production, oxidation catalyst, aluminate catalyst.
Simultaneous Identification of Two Cyclohexanone Oxidation Genes from an Environmental <i>Brevibacterium</i> Isolate Using mRNA Differential Display (2000)

The technique of mRNA differential display was used to identify simultaneously two metabolic genes involved in the degradation of cyclohexanone in a new halotolerant Brevibacterium environmental isolate. In a strategy based only on the knowledge that cyclohexanone oxidation was inducible in this strain, the mRNA population of cells exposed to cyclohexanone was compared to that of control cells using reverse transcription-PCR reactions primed with a collection of 81 arbitrary oligonucleotides. Three DNA fragments encoding segments of flavin monooxygenases were isolated with this technique, leading to the identification of the genes of two distinct cyclohexanone monooxygenases, the enzymes responsible for the oxidation of cyclohexanone. Each monooxygenase was expressed in Escherichia coli and characterized. This work validates the application of mRNA differential display for the discovery of new microbial metabolic genes.
Defects and strain relaxation in silicon-germanium-on-insulator formed by high-temperature oxidation (2004)

SiGe layers were grown on silicon-on-insulator substrates and oxidized at temperatures from 1200 to 1300 °C to form silicon-germanium-on-insualtor (SGOI) layers. Strain relaxation of the SGOI film is shown to be dislocation mediated and the residual strain scaled with the final SGOI thickness in a manner consistent with equilibrium theory. Stacking faults (SF) are observed in the relaxed SGOI layer and their density increases exponentially with decreasing film thickness. In films below ∼500Å, the SF density becomes comparable with the dislocation density which may be responsible for differences between equilibrium and measured residual strain in thin SGOI layers.
Evaluation of Green, Red, and Near Infrared Bands for Predicting Winter Wheat Biomass, Nitrogen Uptake, and Final Grain Yield (2004)

Abstract Presently normalized difference vegetative indexes (NDVI) based on red (RNDVI) or green (GNDVI) reflectance are commonly used to evaluate plant health, biomass, and nutrient content. This study was conducted to determine which of these two indexes is more correlated with biomass, forage nitrogen (N) uptake, and final grain yield of winter wheat. Three experimental sites were established in Oklahoma in the fall of 2001 at Stillwater. Spectral reflectance measurements were taken at Feekes growth stage 4, 6, and 10.5 followed by winter wheat forage harvest. When evaluated at specific stages of growth, RNDVI was consistently more highly correlated with biomass than GNDVI. Green NDVI and RNDVI were more highly correlated with forage N uptake than with dry biomass at each stage of growth, but neither index appeared to have a comparative advantage over the other. Both indexes were highly correlated with final grain yield and grain N uptake across all locations. Neither index appeared to have a sizeable advantage over the other, suggesting that either will perform equally well when predicting forage N uptake, grain yield, and grain N uptake in winter wheat. Red NDVI does appear to be a better predictor of forage biomass, specifically at earlier stages of growth.
Temperature and Volumetric Fraction Measurements in a Hot Gas Laden With Water Droplets (2003)

Two temperatures can be detected in a hot gas laden with water droplets. The lower one is the temperature read by a sensor immersed in the flow. This measurement is affected by significant evaporative cooling resulting in readings much below the real gas temperature. The higher one is the temperature of the gas. The difference between these two temperatures is proportional to the water volumetric fraction in the flow. On this basis, a new technique for the measurement of the water volumetric fraction is proposed. The results are compared with a conventional measurement technique based on optical methods. A novel approach to the gas temperature measurement is also introduced. The sensing device is kept at temperatures exceeding the Leidenfrost transition and therefore it is insensitive to the presence of the water droplets. Independent measurement techniques developed at the Evaporative Cooling Sensor Accuracy Test (ECSAT) facility provide the data to validate the measurements obtained with the Above Leidenfrost Temperature and Evaporative Cooling (ALTEC) sensor.
Real‐time blood‐flow imaging system using ultrasonic doppler techniques (1988)

Abstract Blood flow information has been available without negatively affecting human tissues since ultrasonic Doppler techniques were introduced in medical diagnosis. But difficulties with conventional techniques include the acquisition and display of two‐dimensional data in real‐time. To overcome such difficulties, we developed a real‐time two‐dimensional blood‐flow imaging system using a complex autocorrelation technique which could display flow direction, mean flow velocity, and flow variance. In this system, blood‐flow data are displayed in color and superimposed over a black/white tomographic image (tissue form image). This paper describes an outline of the principle, the configuration of the new system and relevant experimental results. It also discusses problems that arise in employing the technique. Clinical evaluation at hospitals which use the system has proven that the system is very useful for the diagnosis of various diseases.

Vapor phase detection of hydrogen peroxide with ambient sampling chemi/chemical ionization mass spectrometry (2010)

In this paper, we demonstrate a mass spectrometric method for sensitive and rapid detection of gaseous hydrogen peroxide (H2O2) using an ambient sampling chemi/chemical ionization source. Metastable helium atoms (He*) were used as the primary ionizing agents and were generated from a dielectric barrier discharge (DBD) source. A gaseous sample of ambient air was drawn into an enclosed ionization chamber and subsequently mixed with metastable species at sub-atmospheric pressure. O2− ions produced from the ionization of ambient air readily react with H2O2 to form the stable [H2O2 + O2]− cluster ion. A detection limit of 0.8 ppbv was achieved by coupling the ion source to a commercial time-of-flight mass spectrometer. The construction of the ion source is simple, and vapors from bulky objects can also be analyzed directly by placing the sample close to the sampling nozzle. The versatility of this ion source for the application in rapid security screening is demonstrated by non-invasive detection of an aqueous solution of hydrogen peroxide concealed in closed beverage bottles.
