Wettability State and Phase Distributions During Steam Injection with and without Chemical Additives: An Experimental Analysis Using Visual Micromodels (2020)

Summary Phase change plays an essential role in wettability during steam injection, and oil becomes the wetting phase in the steam zone. This study investigates this unfavorable phenomenon using visual data obtained from micromodel experiments and how the wettability can be reversed using chemicals. All measurements were conducted at temperatures up to 200°C on glass-bead micromodels. The models were initially saturated with brine solution and then displaced by two types of mineral oils (450 and 111,600 cp at 25°C). Steam was then constantly injected into the micromodels to evaluate the effect of phase change and wettability status on residual saturation development. Next, chemical additives, screened from the previous contact-angle and thermal-stability measurements, were added to the steam to observe their ability in modifying phase distribution and wettability state. The results showed that phase distribution and residual oil saturation are critically sensitive to the steam phase. At any circumstances, wettability alteration with chemicals was possible. The shape and characteristics of the trapped oil with and without chemicals were identified through micromodel images, and suggestions were made as to the conditions (pressure, temperature, and time to apply during the injection application) at which these chemicals show optimal performance.
Implant dynamics of transcatheter aortic valve implantation in Europe (2013)

Purpose: Transcatheter aortic valve implantation (TAVI) gained Conformité Européenne (CE)-mark approval in 2007, and in subsequent years the number of patients undergoing TAVI in Europe has increased exponentially. Disparate adoption of medical technology is pervasive and results in inequitable patient access. Adoption kinetics of a novel medical technology such as TAVI has not been previously described. We sought to examine the adoption kinetics of TAVI in Western Europe Methods: TAVI adoption was investigated across 11 European nations: Germany, France, Italy, United Kingdom (UK), Spain, The Netherlands, Switzerland, Belgium, Portugal, Denmark and Ireland. Two sources of data were used: (1) lead physicians in each nation provided national registry data; and (2) the European Cardiovascular Monitor system. The penetration of TAVI in each nation was determined as a measure of actual TAVI use relative to potential use. Results: Between January 2007 and December 2011, 34,317 patients underwent TAVI in the 11 study nations. Almost half of all implants were performed in Germany (45.9%). In 2011, the highest annual increase in procedural volume was observed in France (61%) and Germany (49%), while Ireland (-15%) and Portugal (-3%) experienced a decline. We observed a wide variation in the number of TAVI implants per million of population. Germany (88.7) and Portugal (6.1) accounted for the highest and lowest number of TAVI implants per million of population in 2011, respectively. Among the 11 study nations, the mean number of TAVI implants per million was 32.9±24.9. The number of centres performing TAVI increased 9-fold from 37 in 2007 to 342 in 2011. In 2011, Germany (90) and Italy (87) had the highest number of TAVI centres whereas Portugal, Denmark and Ireland (3) had the lowest. Belgium had the highest number of TAVI centres per million (2·1). On average, there were 0·9±0.6 TAVI centres per million. These numbers led to an average of 41±28 TAVI implants per centre in 2011, with estimates in individual countries ranging from 10 in Ireland to 89 in Germany. In 2011, we estimate that there were 28,400 living TAVI recipients and 158,371 potential TAVI candidates in the 11 study nations. Thus, the calculated weighted average TAVI penetration rate was 17.9%. Germany (36.2%) and Portugal had the highest and lowest TAVI penetration rates, respectively. Conclusions: There is substantial variation in the adoption of TAVI and in the annual number of TAVI implants per centre across nations. TAVI remains greatly underutilised with an estimated weighted penetration rate of 17.9%.
Machine System for Harvesting Small Diameter Woody Biomass and Reducing Hazardous Fuels: A Developmental Report (2009)

This is a report on field testing and refinement of the first generation FECON Bio-Harvester, designed to swath harvest small diameter woody biomass of mixed species and size classes. The machine system consisted of a unique harvesting head, a FECON FTX440, a silage dump wagon and roll-on-roll-off bins. The cutting system consists of a rotating drum with cutting tools, followed by an auger and a material fan which blew the harvested biomass into the silage dump wagon. The harvesting head is PTO driven. The machine system was tests in natural forest understory, between rows of pine plantations and in a Pocosin ecosystem. The sites had 6 to 20 green tons per acre of small diameter woody biomass. Below are the resulting harvesting productivity and cost.

Heuristic dynamic programming for semi-active control of vibration isolation (2008)

Vibration isolation controllers are used to suppress undesirable disturbance in order to guarantee better performance in many industrial and scientific domains. To overcome the drawbacks of the conventional passive systems, a novel design based on the action dependent heuristic dynamic programming (ADHDP) is addressed in this paper for the semi-active vibration isolator. ADHDP, derived from dynamic programming, is adopted in the design of a nonlinear optimal vibration controller. This approach is the simplest category of adaptive critic designs (ACDs) which are very efficient to solve a class of nonlinear optimal control problems. Only two subnetworks are involved in ADHDP, namely the action network and the critic network. Least mean square (LMS) algorithm with variable learning rate is applied to the adaptation of these two networks. A single-stage training process is also demonstrated as a useful training strategy. Two types of vibrations are utilized to verify the effectiveness of this control design. Simulation results show that the semi-active vibration isolator is able to reduce the influence of the vibration excitation to the payload significantly in comparison with the passive system.

Immunohistochemistry using an antibody to unphosphorylated connexin 43 to identify human myometrial interstitial cells (2008)

MICs are identified consistently on the boundaries of smooth muscle bundles in both the pregnant and non-pregnant uterus and are distinct from fibroblasts. The uniform distribution of connexin 43 on the cell membrane of MICs, rather than localisation in gap junction plaques, may represent the presence of connexin hemichannels. This antibody specificity may aid future study of this potentially important cell type.
Clustering and linear placement (1972)

This paper presents two algorithms, one for clustering a set of interconnected nodes and the other for forming a linear placement of clustered interconnected nodes. The linear placement algorithm requires the output of clustering as an input. The two algorithms were designed to analyze the structure of digital logic for automatic placement of logic functions on a MOS/LSI chip as part of an automatic layout system8 and so far have only been used for that application. However, the clustering algorithm could be used to analyze any undirected graph. Both algorithms are noniterative and provide very good results with small amounts of computer time.
Surface Nanobubbles Nucleate Microdroplets (2014)

When a hydrophobic solid is in contact with water, surface nanobubbles often form at the interface. They have a lifetime many orders of magnitude longer than expected. Here, we show that they even withstand a temperature increase to temperatures close to the boiling point of bulk water; i.e., they do not nucleate larger bubbles ("superstability"). On the contrary, when the vapor-liquid contact line passes a nanobubble, a liquid film remains around it, which, after pinch-off, results in a microdroplet in which the nanobubbles continue to exist. Finally, the microdroplet evaporates and the nanobubble consequently bursts. Our results support that pinning plays a crucial role for nanobubble stability.
Time-Series Similarity Queries Employing a Feature-Based Approach (1999)

Time-series, or time-sequence, data show the value of a parameter over time. A common query with time-series data is to find all sequences which are similar to a given sequence. The most common technique for evaluating similarity between two sequences involves calculating the Euclidean distance between them. However, many examples can be given where two similar sequences are separated by a large Euclidean distance. In this paper, instead of calculating the Euclidean distance directly between two sequences, the sequences are transformed into a feature vector and the Euclidean distance between the feature vectors is then calculated. Results show that this approach is superior for finding similar sequences. 2.

Fabrication of gating nanopore towards single-biomolecule electrical identification (2012)

We developed a simple fabrication method for a gating nanopore nanostructure, which is composed of a solid-state nanopore and embodied nanogap-electrode inside the nanopore. The method by using deep reactive-ion etching technique achieved a high-yield rate and easily controlled the pore-length for the gating nanopore device. In addition, by using the gating nanopore, we investigated single-particles / biomolecules that pass through a nanopore only by change in electric current not only flowing parallel to a nanopore, but also flowing between nanogap electrodes perpendicular to the nanopore. From the ionic current intensity and its time profiles, we identify a sample single-particles/bioanalytes. The electrical measurement by using gating nanopore would be a promising methodology for single-biomolecule sensors.
Differentiation of Fungi Using Hyperspectral Imagery for Food Inspection (2005)

This paper is part of a project of using hyperspectral imagery to detect pathogens such asmycotoxin-producing fungi, in grain products, such as corn. Traditionally, corn kernels have beenexamined for evidence of bright greenish-yellow fluorescence (BGYF), indicative of the presence ofA. flavus, when illuminated with a high-intensity ultra-violet light. The BGYF approach is time andlabor intensive and somewhat inaccurate. Several previous studies have examined spectral-based,non-destructive methods for the detection of fungi and toxins. This research focuses on usingspectral image data for fungi and toxin detection. A tabletop hyperspectral imaging system, VNIR-100E, is used in the study for high spectral and high spatial resolution spectral data acquisition. Inthis paper, a total of five toxin producing fungal species were used in two experiments. They arePenicillium chrysogenum, Fusarium moniliforme, Aspergillus parasiticus, Trichoderma viride, andAspergillus flavus. All fungal isolates were cultured on agar in Petri-dishes under lab conditions andwere imaged on day 5 of growth. The objective of this study is to use hyperspectral imagery forclassification of different fungi.

Automating UI generation by model composition (2002)

Automated user-interface generation environments have been criticized for their failure to deliver rich and powerful interactive applications. To specify more powerful systems, designers require multiple specialized modeling notations. The model-composition problem is concerned with automatically deriving powerful, correct, and efficient user interfaces from multiple models specified in different notations. Solutions balance the advantages of separating code generation into specialized code generators with deep, model-specific knowledge against the correctness and efficiency obstacles that result from such separation. We present a correct and efficient solution that maximizes the advantage of separation through run-time composition mechanisms.
The effect of corneal thickness on intraocular pressure measurement in patients with corneal pathology (2004)

This study found that mean IOP measurements using the OBF pneumotonometer were significantly higher than those made using the Goldmann applanation tonometer or Tono-Pen in eyes with a variety of cornel pathologies. The OBF pneumotonometer was found to be most affected by variation in CCT. For all three instruments, the relation between IOP and CCT depended on the corneal pathology and was greatest for FED.
Joint Compensation of IQ Imbalance and Phase Noise in OFDM Systems (2006)

The joint effects of IQ imbalance and phase noise on OFDM systems are analyzed, and a compensation scheme is proposed to improve the system performance. The scheme consists of a joint channel estimation algorithm and a joint data symbol estimation algorithm. In the proposed channel estimation algorithm, the channel coefficients are jointly estimated with the IQ imbalance parameters and the phase noise components. Its performance is demonstrated to be close to the associated Cramer-Rao lower bound. In the proposed data symbol estimation algorithm, the joint compensation is decomposed into IQ imbalance compensation and phase noise compensation. It is shown both by theory and computer simulations that the proposed scheme can effectively improve the signal-to-noise ratio at the receiver. As a result, the sensitivity of OFDM receivers to the physical impairments can be significantly lowered, simplifying the RF and analog circuitry design in terms of implementation cost, power consumption, and silicon fabrication yield.
Less conservative robust Kalman filtering using noise corrupted measurement matrix for discrete linear time-varying system (2009)

In this paper, a new class of robust Kalman filtering problem is tackled for time-varying linear systems. Aside from the conventional problem settings, it is assumed that the measurement matrix be unknown and only a noise corrupted observation of it be available for state estimation. The influence of the noise contaminated measurement matrix on the Kalman filter estimate is analyzed in the sense of classical weighted least-squares criterion. Stochastic approximations of estimation errors due to noisy measurement matrix make it possible to develop a less conservative robust estimation scheme. Reinterpreting the stochastic error compensation procedure, the less conservative robust Kalman filtering problem is defined as finding a unique minimum of an indefinite quadratic cost. By solving the single stage optimization problem, the robust filter recursion is derived. As well, its existence condition is recursively checked using the estimation error covariance. It is also shown that the proposed filter is consistent in probability. A practical design example related to frequency estimation of noisy sinusoidal signal is given to verify the estimation performance of the proposed scheme.

Global analysis of cellular protein flux quantifies the selectivity of basal autophagy (2016)

In eukaryotic cells, the macroautophagy pathway has been implicated in the degradation of long-lived proteins and damaged organelles. Although it has been demonstrated that macroautophagy can selectively degrade specific targets, its contribution to the basal turnover of cellular proteins had previously not been quantified on proteome-wide scales. In a recent study, we utilized dynamic proteomics to provide a global comparison of protein half-lives between wild-type and autophagy-deficient cells. Our results indicated that in quiescent fibroblasts, macroautophagy contributes to the basal turnover of a substantial fraction of the proteome. However, the contribution of macroautophagy to constitutive protein turnover is variable within the proteome. The methodology outlined in the study provides a global strategy for quantifying the selectivity of basal macroautophagy.
The 68040 integer and floating-point units (2002)

The integer, floating-point, and on-chip memory subsystems of the Motorola 68040 microprocessor operate in parallel to achieve four times the performance of a 68020 microprocessor and ten times the performance of a 68882 floating-point coprocessor. The integer and floating-point units are described in terms of their performance, internal architecture, and methods used to obtain this performance. The 68040 integer unit (IU) is optimized to execute the most common instructions in a single cycle while maintaining user code compatibly with the 68000 family. To increase performance, the 68040 reduces both the number of arithmetic logic unit (ALU) cycles per instruction (CPI) and the ALU cycle time. The 68040 has a six-stage pipe consisting of an instruction prefetch stage, a program counter calculation and decode stage, an effective address calculation stage for operands, a data execute stage, and a write-back stage. The 68040 floating-point unit (FPU) conforms to the IEEE 754 floating-point standard via a software envelope.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
ADIperf: A Framework for Application-driven IoT Network Performance Evaluation (2022)

The Internet of Things (IoT) is the convergence of the physical and the digital worlds. It enables a large spectrum of applications such as smart building, smart tracking, smart metering, predictive maintenance, remote control, augmented reality or video surveillance. The diversity of these applications has caused a profusion of the IoT communication technologies offerings for exchanging data between IoT devices and applications. The latter technologies come with different features in terms of range, throughput, latency, scalability, energy, etc. Each technology can fit several use cases and a use case can leverage several technologies. It is complex, yet critical, for an IoT architect to evaluate the adequacy and the limits of a network technology for a targeted application and to continuously optimize its configuration as the deployment evolves. This paper introduces ADIperf, a framework to simplify and systematize the evaluation of the performance of an IoT communication technology for a given IoT use case and context. The ADIperf approach pays special attention to the energy efficiency as well as to the ability of an IoT communication technology to properly scale up with the number of end-devices, with the ultimate goal of giving guidelines and tools for IoT architects to select the technology and configure the network that fulfill their application's needs over time.
UPTAKE OF VARIOUS RADIONUCLIDES BY HYDROTHERMALLY PREPARED MOLYBDENUM PHOSPHATES (2001)

A series of molybdenum phosphates with three different structures were synthesized hydrothermally. The types include a one-dimensional polymer, (PPh4)2[(H3O)2NaMo6P4O24(OH)7]·5H2O; a microporous material with a framework structure, (TMA)2(NH4)2 [Fe2Mo12O30(H2PO4)6(HPO4)2]·nH2O; and three compounds with layered structures, [N(C3H7)4(NH4)][(MoO)4O4(PO4)2], KMo(H2O)O2PO4, and NH4Mo(H2O)O2PO4. These compounds were tested for their ability to remove the radionuclides commonly found in nuclear waste solutions (85Sr, 134Cs, 57Co, 65Zn, 59Fe, 54Mn, 51Cr, 110Ag, 236Pu, and 241Am). Experiments were carried out to determine the distribution coefficients (KDs) of the radionuclides in several “model” solutions (0.1 M HNO3, 0.1 M NaNO3, 0.1 M NaNO3/0.1 M NaOH). A well-known ammonium 12-molybdophosphate (AMP), prepared by cold synthesis, was tested in parallel for reference in acidic media. Of the tested materials, ferric molybdenum phosphate took up several radionuclides rather well in neutral and alkaline conditions and was selective for 241Am in 0.1 M HNO3 (KD = 2140mL/g). The hydrothermally prepared NH4MoPO was very selective for 134Cs, having a KD of 23,400 mL/g in 0.1 MHNO3, about half of that of AMP (44,000 mL/g). Sodium molybdenum phosphate took up both 236Pu and 241Am in 0.1 M HNO3 well, the KDs being 3350 and 8600 mL/g, respectively. Otherwise, the materials took up few of the tested radionuclides selectively as the KDs were usually below 1000 mL/g.
