The paper presents a NO/sub x/ detector made by thick film technology. The two plated electrodes using a conductive Pd-Ag ink were deposited on one side of the alumina substrate. A thick-film heater material is pasted on the other side of the substrate the sensitive film, was produced, by a TiO/sub 2/-Al/sub 2/O/sub 3/ resistive ink. The device electrical resistance decrease from 200 K/spl Omega/ in pure air to 36 K/spl Omega/ in a 2000 ppm NO/sub x/ atmosphere for a working temperature of 450/spl deg/C.
Unmet medical needs and therapeutic goals in the treatment of type 2 diabetes. (2003)

One of the main goals in the treatment of type 2 diabetes mellitus is to produce near-normal glucose levels to prevent the development of diabetic complications. Available treatments do not succeed in restoring normoglycemia in the long term. The recently improved knowledge of key pathogenic mechanisms of type 2 diabetes has led to a multitude of new molecular targets. The main goal is the maintenance of beta-cell function, as its decline is the major reason for impairment in glucose tolerance over time. Other tissues or systems may also be interesting targets. No single drug is likely to reverse all aspects of the disease, but the main aim is to provide more effective, better tolerated and better patient-tailored combinations.
Desiccation of callus enhances somatic embryogenesis and subsequent shoot regeneration in sugarcane (2009)

Callus cultures were established in three commercial sugarcane varieties, viz., CoJ 64, CoJ 83 and CoJ 86, from spindle leaf segments on Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D; 4 mg/L) and 6-benzylaminopurine (BAP; 0.5 mg/L). The calli were sub-cultured on MS+2,4-D (2 mg/L)+BAP (0.5 mg/L)+agar (0.8% w/v) medium (control) and MS+2,4-D (2 mg/L)+BAP (0.5 mg/L)+agar (1.6% w/v) medium (treatment) to study the effect of desiccation caused by double agar on somatic embryogenesis. Per cent somatic embryogenesis observed in treatment-calli of sugarcane varieties CoJ 64, CoJ 83 and CoJ 86 was 90, 90.63 and 89.66, respectively; while in control-calli the corresponding figures were 66.67, 64.52 and 63.33. Likewise, shoot regeneration from desiccated calli on MS+BAP (0.5 mg/L) medium was also higher over non-desiccated control, i.e., 84.27, 86.52 and 83.13% as compared to 54.35, 56.25 and 50.38%, respectively in CoJ 64, CoJ 83 and CoJ 86. Thus, this fairly simple double agar medium provided an alternative method for improving somatic embryogenesis and, hence, regeneration frequency of sugarcane callus.
Ultrasonic velocities in pure hydrocarbons and mixtures (1991)

Ultrasonic velocities were measured in hydrocarbons of n-alkanes, 1-alkenes, and naphthenes as a function of temperature, using the ultrasonic pulse transmission method. The velocities of all the hydrocarbons measured decrease with increasing temperature approximately linearly, although the rate of decrease is different for different hydrocarbons. The data also show that hydrocarbons of the same homologous series with higher carbon content have higher bulk moduli (or lower compressibilities) and the measured velocities V in mixtures of these pure hydrocarbons obey a simple physical mixing law V=Σi=1nXiVi, where Xi is the volume fraction and Vi is the velocity, respectively, of the ith component.
The frequency domain analysis of a novel extended tension leg platform (2016)

Tension leg platform (TLP) is a kind of offshore structures for oil or gas exploration in deep-water which has its special feature as partly compliant and partly rigid. Extended tension leg platform (ETLP) is the third generation of TLP which made an improvement on the basis of typical TLP structure. Extended structure is the most notable feature of ETLP which could increase the distance of groups of tethers and magnify the restoring moment. A novel ETLP which consists of four columns and a ring pontoon is proposed in this paper. Four box beams are welded onto each other and formed a ring pontoon. It makes the extended structures to be parts of the pontoons. This design decreases the number of blocks and welds needed for construction, which means the construction cost and period can be reduced, and the structure intensity and fatigue reliability can be enhanced. In this paper, a frequency domain numerical analysis is carried out using HydroD module of SESAM software. The natural periods, the hydrodynamic parameters and motion amplitude response function or response amplitude operator (RAO) of novel ETLP are obtained. The results indicate the natural periods of novel ETLP can satisfy the requirement of API. The novel ETLP has a reasonable hydrodynamic performance, and the asymmetry structure has a negligible impact on yaw performance. The novel ETLP provides an alternative for the structure design of deepwater floating platform, and is significant for launching and optimizing the devising of TLP in future.
Predominant induction of gelsolin and actin-binding protein during myeloid differentiation. (1988)

Three actin-associated proteins, actin-binding protein, gelsolin, and profilin, influence gelation, solation, and polymerization, respectively, of actin in vitro. As assessed with specific cDNA probes and immunoaffinity reagents, a 7-50-fold increase in gelsolin, 3-5-fold increase in actin-binding protein, and less than 2-fold increases in actin and profilin protein and mRNA levels accompanied tetradecanoylphorbolacetate-induced differentiation of the myeloid cell lines U937 and HL60 into macrophage-like cells. Such induction in actin-binding protein or gelsolin did not occur in K562 cells, which respond minimally to tetradecanoylphorbolacetate, or following 1,25-dihydroxyvitamin D3-induced monocyte-like differentiation of U937, which results in a less motile phenotype. These observations suggest that increases in gelsolin and actin-binding protein are essential to the expression of many regulated motile functions which takes place during differentiation of myeloid cells.
Hard Real-Time Hybrid Garbage Collection with Low Memory Requirements (2006)

Real-time garbage collection algorithms are usually criticised for their high memory requirements. Even when consuming nearly 50% of CPU time, some garbage collectors ask for at least twice the memory as really needed. This paper explores the fundamental reason for this problem and proposes a new performance indicator for the evaluation of real-time garbage collection algorithms. Use of this performance indicator motivates an algorithm that combines both reference counting and mark-and-sweep techniques. In the presence of our collector, a garbage collected hard real-time system can achieve the correct balance of time-space tradeoff with less effort. In order to provide both temporal and spatial guarantees needed by a hard real-time application, an offline analysis is developed and integrated into the response time analysis framework. Moreover, the use of dual priority scheduling of the garbage collection tasks allows spare capacity in the system to be reclaimed whilst guaranteeing deadlines
Vision Aided Stabilization and the Development of a Quad-Rotor Micro UAV (2007)

Micro Unmanned Air Vehicles are well suited for a wide variety of applications in agriculture, homeland security, military, search and rescue, and surveillance. In response to these opportunities, a quad-rotor micro UAV has been developed at the Robotic Vision Lab at Brigham Young University. The quad-rotor UAV uses a custom, low-power FPGA platform to perform computationally intensive vision processing tasks on board the vehicle, eliminating the need for wireless tethers and computational support on ground stations. Drift stabilization of the UAV has been implemented using Harris feature detection and template matching running in real-time in hardware on the on-board FPGA platform, allowing the quad-rotor to maintain a stable and almost drift-free hover without human intervention.
Mutational Analysis of ABCG2:  Role of the GXXXG Motif (2004)

ABCG2 (BCRP/MXR/ABCP) is a half-transporter associated with multidrug resistance that presumably homodimerizes for function. It has a conserved GXXXG motif in its first transmembrane segment, a motif that has been linked with dimerization in other proteins, e.g., glycophorin A. We substituted either or both glycines of this GXXXG motif with leucines to evaluate the impact on drug transport, ATP hydrolysis, cross-linking, and susceptibility to degradation. All mutants also carried the R482G gain-of-function mutation, and all migrated to the cell surface. The mutations resulted in lost transport for rhodamine 123 and impaired mitoxantrone, pheophorbide a, and BODIPY-prazosin transport, particularly in the double leucine mutant (G406L/G410L). Basal ATPase activity of the G406L/G410L mutant was comparable to the empty vector transfected cells with no substrate induction. Despite impaired function, the mutants retained susceptibility to cross-linking using either disuccinimidyl suberate (DSS) or the reducible dithiobis(succinimidyl propionate) (DSP) and demonstrated a high molecular weight complex under nonreducing conditions. Mutations to alanine at the same positions yielded fully functional transporters. Finally, we exposed cells to mitoxantrone to promote folding and processing of the mutant proteins, which in the leucine mutants resulted in increased amounts detected on immunoblot and by immunofluorescence. These studies support a hypothesis that the GXXXG motif promotes proper packing of the transmembrane segments in the functional ABCG2 homodimer, although it does not solely arbitrate dimerization.
SIED: software implemented error detection (2004)

This paper presents a new error detection technique called software implemented error detection (SIED). The proposed method is based on a new control check flow scheme combined with software redundancy. The distinctive advantage of the SIED approach over other fault tolerance techniques is the fault coverage. SIED is able to cope with faults affecting data and the program control flow. By-applying the proposed approach on several benchmark programs, we evaluate the error detection capabilities by means of several fault injection experiments. Experimental results underline very good error detection capabilities for the obtained hardened version of selected benchmark programs.
Bonding Technique Using Micro-Scaled Silver-Oxide Particles for <I>In-Situ</I> Formation of Silver Nanoparticles (2008)

We investigated a new bonding technique utilizing micro-scaled silver-oxide (Ag2O) particles. The results of our investigations revealed that bonding between electrodes using for semiconductor modules can be accomplished by adding myristyl alcohol to silver-oxide particles, followed by heating the mixture in air at 300°C under a pressure of 2.5 MPa. Since this bonding technique produces silver particles with a size of a few nanometers when the silver oxide is reduced by the presence of the alcohol, low-temperature sintering and bonding can be achieved.
Heat‐Killed Lactic Acid Bacteria Enhance Immunomodulatory Potential by Skewing the Immune Response toward Th1 Polarization (2011)

Heat-killed lactic acid bacteria not only possess immunomodulatory functions but also provide the advantages of longer product shelf life, easier storage, and more convenient transportation. To establish appropriate heat treatments for the industrial preparation of probiotics with immunomodulatory effects, 4 different heat treatments were used to kill 11 strains of lactic acid bacteria. Comparisons among the strains and with viable forms were carried out in terms of immunomodulatory activity and adhesion to Caco-2 cells. Field-emission scanning electron microscope (FE-SEM) was employed to observe morphological changes in bacteria after heating. Among the 11 viable strains, Lactobacillus gasseri AI-88 was the strongest inducer of interferon-gamma (IFN)-γ and interleukin (IL)-12p70 production. However, after heat treatments its stimulatory ability was attenuated. Heat-killed Enterococcus faecalis YM-73 and Lactobacillus salivarius AP-32 strains showed enhanced stimulation of IFN-γ and IL-12p70 secretion and coincidental decrease in IL-13 production. The adhesion of lactic acid bacteria to Caco-2 cells decreased with increases in temperature. However, heat exposure did not influence immunomodulatory activity. With rising temperature, roughness and unevenness of bacterial cell surfaces increased significantly. The results indicated that heat-killed E. faecalis YM-73 and L. salivarius AP-32 have immunomodulatory ability via increased Th1-associated cytokines and reduced Th2-associated cytokines, switching the immune response from a Th2 toward a Th1 response. These 2 heat-killed strains have the potential for development as commercial products.
TGSum: Build Tweet Guided Multi-Document Summarization Dataset (2016)

The development of summarization research has been significantly hampered by the costly acquisition of reference summaries. This paper proposes an effective way to automatically collect large scales of news-related multi-document summaries with reference to social media's reactions. We utilize two types of social labels in tweets, i.e., hashtags and hyper-links. Hashtags are used to cluster documents into different topic sets. Also, a tweet with a hyper-link often highlights certain key points of the corresponding document. We synthesize a linked document cluster to form a reference summary which can cover most key points. To this aim, we adopt the ROUGE metrics to measure the coverage ratio, and develop an Integer Linear Programming solution to discover the sentence set reaching the upper bound of ROUGE. Since we allow summary sentences to be selected from both documents and high-quality tweets, the generated reference summaries could be abstractive. Both informativeness and readability of the collected summaries are verified by manual judgment. In addition, we train a Support Vector Regression summarizer on DUC generic multi-document summarization benchmarks. With the collected data as extra training resource, the performance of the summarizer improves a lot on all the test sets. We release this dataset for further research.
Detection and tracking of traffic signs using a recursive Bayesian decision framework (2011)

In this paper we propose a new method for the automatic detection and tracking of road traffic signs using an on-board single camera. This method aims to increase the reliability of the detections such that it can boost the performance of any traffic sign recognition scheme. The proposed approach exploits a combination of different features, such as color, appearance, and tracking information. This information is introduced into a recursive Bayesian decision framework, in which prior probabilities are dynamically adapted to tracking results. This decision scheme obtains a number of candidate regions in the image, according to their HS (Hue-Saturation). Finally, a Kalman filter with an adaptive noise tuning provides the required time and spatial coherence to the estimates. Results have shown that the proposed method achieves high detection rates in challenging scenarios, including illumination changes, rapid motion and significant perspective distortion.
Soft handoff analysis of CDMA systems using novel switched-beam smart antennas with polarization diversity (2002)

A novel switched-beam structure is proposed to provide both beam and polarization diversities. Comparing to the conventional switched-beam structure, a 2.2 dB gain in signal to interference ratio is derived from soft handoff simulations in cellular CDMA systems.

During the recent years, proton beam therapy practice has been dramatically advanced from passive-scattering (PS) to Pencil Beam Scanning (PBS) technique [1]. Such evolution not only has improved t...
A study on tree matching model and algorithm towards metadata (2010)

This paper presents an approach for automated mapping metadata according to the characteristics of metadata. A metadata tree matching model is constructed with tree matching theory. First, the metadata should be transformed as a rooted unordered tree. Then, node and structural matching could be conducted. Finally, we get metadata node pairs matched successfully. Accordingly a metadata tree matching algorithm is proposed based on tree path matching. The matching model and algorithm can be applied in automated mapping of heterogeneous metadata, which could construct the foundation of information resource integration, management and interaction.
The florence 2D/3D hybrid face dataset (2011)

This article describes a new dataset under construction at the Media Integration and Communication Center and the University of Florence. The dataset consists of high-resolution 3D scans of human faces along with several video sequences of varying resolution and zoom level. Each subject is recorded under various scenarios, settings and conditions. This dataset is being constructed specifically to support research on techniques that bridge the gap between 2D, appearance-based recognition techniques, and fully 3D approaches. It is designed to simulate, in a controlled fashion, realistic surveillance conditions and to probe the efficacy of exploiting 3D models in real scenarios.
Molecular dynamics and free-energy calculations applied to affinity maturation in antibody 48G7 (1999)

We investigated the relative free energies of hapten binding to the germ line and mature forms of the 48G7 antibody Fab fragments by applying a continuum model to structures sampled from molecular dynamics simulations in explicit solvent. Reasonable absolute and very good relative free energies were obtained. As a result of nine somatic mutations that do not contact the hapten, the affinity-matured antibody binds the hapten >10(4) tighter than the germ line antibody. Energetic analysis reveals that van der Waals interactions and nonpolar contributions to solvation are similar and drive the formations of both the germ line and mature antibody-hapten complexes. Affinity maturation of the 48G7 antibody therefore appears to occur through reorganization of the combining site geometry in a manner that optimizes the balance of gaining favorable electrostatic interactions with the hapten and losing those with solvent during the binding process. As reflected by lower rms fluctuations in the antibody-hapten complex, the mature complex undergoes more restricted fluctuations than the germ line complex. The dramatically increased affinity of the 48G7 antibody over its germ line precursor is thus made possible by electrostatic optimization.
The cold drawing of high polymers (1954)

Abstract Like many other polymers, amorphous polyethyleneterephthalate cold draws in the shoulders of a neck when stretched at room temperature. The draw ratio across the shoulders is not a constant for the polymer, but is found to depend on the temperature and speed of stretching, and on the initial specimen cross-section and birefringence. A local temperature rise is also observed in the shoulders. Isothermal load-extension curves have therefore been measured from 20 to 140°C, and from them an adiabatic load-extension curve has been calculated. This has a negative slope range which appears to be unstable. An alternative process of extension at constant tension in a shoulder, coupled with exchanges of heat along the specimen by conduction, appears to be possible at a lower tension than that needed for pure adiabatic extension. For this second process the length of the shoulder, the tension at which it operates, and the draw ratio across it, can be calculated from the simple adiabatic curve and are found to agree with experimental data within a factor of two. This theory is then used to discuss cold drawing in some other polymers.
Effect of atomization variables on powder characteristics in the high-pressured water atomization process (1990)

High-pressured water atomization is a viable production method for fine metal powders used for metal injection moulding and for additives in sintered parts. The atomization mechanism using two types of water jet nozzle (Cone and V-jet nozzle) under high pressure up to 70MPa was studied. The pulverizing capability under high-pressured water atomization strongly depends on a gas stream induced by the ejecting effect of water jets, which surround the melt stream. A mean particle diameter of less than 10 μm can be obtained by the V-jet nozzle.
Hollow Silica Spheres: Synthesis and Mechanical Properties (2009)

Core-shell polystyrene-silica spheres with diameters of 800 nm and 1.9 microm were synthesized by soap-free emulsion and dispersion polymerization of the polystyrene core, respectively. The polystyrene spheres were used as templates for the synthesis of silica shells of tunable thickness employing the Stöber method [Graf et al. Langmuir 2003, 19, 6693]. The polystyrene template was removed by thermal decomposition at 500 degrees C, resulting in smooth silica shells of well-defined thickness (15-70 nm). The elastic response of these hollow spheres was probed by atomic force microscopy (AFM). A point load was applied to the particle surface through a sharp AFM tip, and successively increased until the shell broke. In agreement with the predictions of shell theory, for small deformations the deformation increased linearly with applied force. The Young's modulus (18 +/- 6 GPa) was about 4 times smaller than that of fused silica [Adachi and Sakka J. Mater. Sci. 1990, 25, 4732] but identical to that of bulk silica spheres (800 nm) synthesized by the Stöber method, indicating that it yields silica of lower density. The minimum force needed to irreversibly deform (buckle) the shell increased quadratically with shell thickness.
Etching of Thermal Oxides in Low Pressure Anhydrous  HF  /  CH 3 OH  Gas Mixture at Elevated Temperature (1993)

Etching of thermal oxides in gas mixture at the pressure from 100 to 500 Torr and wafer temperatures from 25 to 120°C is studied using a commercial cluster tool compatible reactor. Pressure and temperature are selected to control condensation of reactants on the etched surfaces, and hence, the thermal oxide etch rate. Using this etching mode, controlled etching of thermal oxides at rates up to 200 Å/min was achieved without any water vapor intentionally added to the input gases.
