Performance of adaptive array antenna with arbitrary geometry in the presence of mutual coupling (2006)

The effect of the mutual coupling between the array elements on the performance of the adaptive array antennas (AAA) is investigated when the actual received voltages which include the mutual coupling are directly used to estimate the weight vector based on the adaptive algorithm. The output signal-to-interference-noise ratio (SINR), the convergence of the adaptive algorithm and the synthesized pattern are evaluated to study the effect due to the existence of the mutual coupling. It is found that the mutual coupling affects the antenna adaptive gain, but does not affect the adaptive processing. It is also found that the mutual coupling does not always degrade the iterative convergence of the adaptive algorithm. It is proved that any invertible matrix for compensating the mutual coupling cannot improve the output SINR. It is also indicated that the radiation pattern can be correctly synthesized in the presence of the mutual coupling by introducing the universal steering vector (USV) whose element corresponds to the array element pattern.
CPAM: a common power analysis methodology for high-performance VLSI design (2002)

A common power analysis methodology has been developed to estimate on-chip thermal power, identify potential electromigration problems, and minimize power supply noise. Comprehensive analysis results from CPAM provide the critical data needed to improve system performance and reliability for high-end processor design.
The impact of microglial activation on blood-brain barrier in brain diseases (2014)

The blood-brain barrier (BBB), constituted by an extensive network of endothelial cells (ECs) together with neurons and glial cells, including microglia, forms the neurovascular unit (NVU). The crosstalk between these cells guarantees a proper environment for brain function. In this context, changes in the endothelium-microglia interactions are associated with a variety of inflammation-related diseases in brain, where BBB permeability is compromised. Increasing evidences indicate that activated microglia modulate expression of tight junctions, which are essential for BBB integrity and function. On the other hand, the endothelium can regulate the state of microglial activation. Here, we review recent advances that provide insights into interactions between the microglia and the vascular system in brain diseases such as infectious/inflammatory diseases, epilepsy, ischemic stroke and neurodegenerative disorders.
Enzyme kinetic studies in cell populations using fluorogenic substrates and flow cytometric techniques (1980)

Abstract Two flow cytometers, an Ortho Cytofluorograf model 4800A and a “custom” built dual laser instrument, have been interfaced with a PDP 11/40 computer to assay the rate of accumulation of fluorescent products in populations of single cells due to enzymatic hydrolysis of fluorogenic substrates. Esterase activity assayed with fluorescein diacetate exhibited abnormal Michaelis‐Menten kinetic behavior in EMT6 cells. This was in marked contrast to normal kinetics obtained with homogenates assayed with a conventional spectrofluorimeter. Moreover, the homogenates were 4 5x less efficient at converting substrate than were intact cells. Fluorescein diacetate is lipophilic and the induced fluorescence was evenly distributed throughout intact cells. In contrast a second substrate studied, 3‐O‐methyl fluorescein phosphate, is lipophobic and highly polar and the induced fluorescence was located at the cell surface. Results obtained with this substrate suggested that membrane, but not intracellular phosphatases were being assayed. Although the reaction product appeared to be lost rapidly from the site of hydrolysis it was possible to extract K m and V max for the dephosphorylation which followed normal kinetics. The dual laser flow cytometer was built to study 4‐methylum‐belliferone based substrates (UV excitation) simultaneously with those based on fluorescein. An assay using fluorescein diacetate and 4‐methylumbelliferyl acetate simultaneously was able to discriminate between a mouse mammary tumour (EMT6) and a human colonic adenocarcinoma cell line (HT 29). Furthermore, incubation of both cell lines for up to 6 hr with these substrates maintained viability at about 90%.

Substitutions near the HA receptor binding site explain the origin and major antigenic change of the B/Victoria and B/Yamagata lineages (2022)

Influenza B virus primarily infects humans, causing seasonal epidemics globally. Two antigenic variants-Victoria-like and Yamagata-like-were detected in the 1980s, of which the molecular basis of emergence is still incompletely understood. Here, the antigenic properties of a unique collection of historical virus isolates, sampled from 1962 to 2000 and passaged exclusively in mammalian cells to preserve antigenic properties, were determined with the hemagglutination inhibition assay and an antigenic map was built to quantify and visualize the divergence of the lineages. The antigenic map revealed only three distinct antigenic clusters-Early, Victoria, and Yamagata-with relatively little antigenic diversity in each cluster until 2000. Viruses with Victoria-like antigenic properties emerged around 1972 and diversified subsequently into two genetic lineages. Viruses with Yamagata-like antigenic properties evolved from one lineage and became clearly antigenically distinct from the Victoria-like viruses around 1988. Recombinant mutant viruses were tested to show that insertions and deletions (indels), as observed frequently in influenza B virus hemagglutinin, had little effect on antigenic properties. In contrast, amino-acid substitutions at positions 148, 149, 150, and 203, adjacent to the hemagglutinin receptor binding site, determined the main antigenic differences between the Early, Victoria-like, and Yamagata-like viruses. Surprisingly, substitutions at two of the four positions reverted in recent viruses of the Victoria lineage, resulting in antigenic properties similar to viruses circulating ∼50 y earlier. These data shed light on the antigenic diversification of influenza viruses and suggest there may be limits to the antigenic evolution of influenza B virus.
An inverse signal approach to computing the envelope of a real valued signal (1998)

We address the problem of estimating the envelope of a real valued signal, s(t) that is observed for a duration of T seconds. We model s(t) using a Fourier series, by considering periodic extensions of the signal. By using an analog of the auto-correlation method of linear prediction on the Fourier coefficients of s(t) the envelope of the signal is estimated without explicitly computing the analytic signal.
Visualization and Interactive Manipulation of Color Gamuts (2002)

Several tools and techniques for the visualization of color gamuts have been presented in the past. We present a short survey on the topic, and conclude that tools with the possibility for interactive color adjustment in some color space are almost absent. Therefore, a new tool which combines the known techniques with the possibility of interactive gamut mapping is presented along with suggestions for future work. The motivation for developing the new tool is threefold: First, it will serve as an important pedagogical tool in the teaching of color engineering. Secondly, we believe that the tool will prove helpful in research related to color reproduction. Finally, we hope that the tool can be used in the production of high quality color images in the future.
A Machine Learning-Genetic Algorithm (ML-GA) Approach for Rapid Optimization Using High-Performance Computing (2018)

<div class="section abstract"><div class="htmlview paragraph">A Machine Learning-Genetic Algorithm (ML-GA) approach was developed to virtually discover optimum designs using training data generated from multi-dimensional simulations. Machine learning (ML) presents a pathway to transform complex physical processes that occur in a combustion engine into compact informational processes. In the present work, a total of over 2000 sector-mesh computational fluid dynamics (CFD) simulations of a heavy-duty engine were performed. These were run concurrently on a supercomputer to reduce overall turnaround time. The engine being optimized was run on a low-octane (RON70) gasoline fuel under partially premixed compression ignition (PPCI) mode. A total of nine input parameters were varied, and the CFD simulation cases were generated by randomly sampling points from this nine-dimensional input space. These input parameters included fuel injection strategy, injector design, and various in-cylinder flow and thermodynamic conditions at intake valve closure (IVC). The outputs (targets) of interest from these simulations included five metrics related to engine performance and emissions. Over 2000 samples generated from CFD were then used to train an ML model that could predict these five targets based on the nine input features. A robust super learner approach was employed to build the ML model, where results from a collection of different ML algorithms were pooled together. Thereafter, a stochastic global optimization genetic algorithm (GA) was used, with the ML model as the objective function, to optimize the input parameters based on a merit function so as to minimize fuel consumption while satisfying CO and NO<sub>x</sub> emissions constraints. The optimized configuration from ML-GA was found to be very close to that obtained from a sequentially performed CFD-GA approach, where a CFD simulation served as the objective function. In addition, the overall turnaround time was (at least) 75% lower with the ML-GA approach, as the training data was generated from concurrent CFD simulations and employing the ML model as the objective function significantly accelerated the GA optimization. This study demonstrates the potential of ML-GA and high-performance computing (HPC) to reduce the number of CFD simulations to be performed for optimization problems without loss in accuracy, thereby providing significant cost savings compared to traditional approaches.</div></div>
Assistant Principals’ Perceptions of the Principalship (2018)

Education research has established a significant relationship between school leadership and students’ achievement. This study considered the leadership self-efficacy and practice of public school assistant principals (AP) in the domains of facilitating a supportive collaborative learning environment, instructional leadership, school improvement, management, and family and community relations, as perceived by APs' self-report. Findings of this study suggest that,Â in addition to the strengths in the domain of facilitating a collaborative learning environment and efficacy around family and community engagement, there were explicit gaps in the instructional leadership and school improvement practices of APs that need to be addressed. The study also confirmed that there continues to be a proliferation of duties and a lack of consistent set of practices.
Missing log data interpolation and semiautomatic seismic well ties using data matching techniques (2019)

Relating well-log data, measured in depth, to seismic data, measured in time, typically requires estimating well-log impedance and a time-to-depth relationship using available sonic and density logs. When sonic and density logs are not available, it is challenging to incorporate wells into integrated reservoir studies because the wells cannot be tied to seismic. We have developed a workflow to estimate missing well-log information, automatically tie wells to seismic data, and generate a global well-log property volume using data matching techniques. We first used the local similarity scan to align all logs to constant geologic time and interpolate missing well-log information. Local similarity is then used to tie available wells with seismic data. Finally, log data from each well are interpolated along local seismic structures to generate global log property volumes. We use blind well tests to verify the accuracy of well-log interpolation and seismic well ties. Applying our workflow to a 3D seismic data set with 26 wells achieves consistent and verifiably accurate results.
Triplet Constrained Deep Feature Extraction for Hyperspectral Image Classification (2018)

Convolutional neural networks (CNNs) have demonstrated significant performance in various visual recognition problems in recent years. Recent research has shown that training multilayer neural networks can extensively improve the performance of hyperspectral image (HSI) classification. In this paper, we apply a triplet constraint property on a 3D CNN. This method directly learns a mapping from images to a Euclidean space in which distances directly correspond to a measure of spectral-spatial similarity. Once this embedding has been established, classification can be implemented with such embeddings as feature vectors. Moreover, we also augment the size of the training samples in different band groups. This produces different yet useful estimation of spectral-spatial characteristics of HSI data and contributes considerably in accurate classification. This method is evaluated on a new dataset and compared with several state-of-the-art models, which shows the promising potential of our method.
Predictable Broadcasting of Parallel Intents in Real-Time Android (2014)

Several approaches to extend the original Android implementation with real-time capabilities were presented in the last few years. Most of the research was limited to fundamental issues like real-time scheduling and non-blocking memory management. This paper demonstrates the weak predictability of Android's intra- and inter-process communication and presents a concept to improve its soft real-time capability. The proposed approach introduces a priority-based broadcast handling, instead of the original first in -- first out processing. Additionally, we reduce the size of responsible critical sections in order to improve the preemptibility and assure predictable delays for applications with real-time requirements. Our empirical evaluation highlights the improvements in comparison to the original Android implementation without loss of the performance for both global and local broadcast systems. Furthermore, the compatibility to already existing components and applications is preserved.
YNU-HPCC at SemEval 2017 Task 4: Using A Multi-Channel CNN-LSTM Model for Sentiment Classification (2017)

In this paper, we propose a multi-channel convolutional neural network-long shortterm memory (CNN-LSTM) model that consists of two parts: multi-channel CNN and LSTM to analyze the sentiments of short English messages from Twitter. Unlike a conventional CNN, the proposed model applies a multi-channel strategy that uses several filters of different length to extract active local n-gram features in different scales. This information is then sequentially composed using LSTM. By combining both CNN and LSTM, we can consider both local information within tweets and long-distance dependency across tweets in the classification process. Officially released results show that our system outperforms the baseline algorithm.

Enzymatic modification of triacylglycerols of high eicosapentaenoic and docosahexaenoic acids content to produce structured lipids (1999)

Abstract Immobilized lipase, IM60, from Rhizomucor miehei was used as a biocatalyst for the incorporation of capric acid (C10:0) into fish oil originally containing 40.9 mol% eicosapentaenoic (20:5n‐3) and 33.0 mol% docosahexaenoic (22:6n‐3) acid. Acidolysis was performed with and without organic solvent. Pancreatic lipase‐catalyzed sn ‐2 positional analysis was performed after enzymatic modification. Tocopherol analysis was performed before and after enzymatic modification. Products were analyzed by gas‐liquid chromatography. After a 24‐h incubation in hexane, there was an average of 43.0±1.6 mol% incorporation of C10:0 into fish oil, while 20:5 and 22:6 decreased to 27.8±2.2 and 23.5±1.3 mol%, respectively. The solvent‐free reaction produced an average of 31.8±8.5 mol% C10:0 incorporation, while 20:5 and 22:6 decreased to 33.2±3.3 and 28.3±3.9 mol%, respectively. The effect of incubation time, substrate molar ratio, enzyme load, and added water were also studied. In general, as the enzyme load, molar ratio, and incubation time increased, mol% C10:0 incorporation also increased. The optimal mol% C10:0 incorporation was 41.2% at 48 h for the reaction in hexane and 46.4% at 72 h for the solvent‐free reaction. The highest C10:0 incorporation (65.4 mol%) occurred at a molar ratio of 1:8 (fish oil triacylglycerols/capric acid) in hexane. For the solvent‐free reaction, the optimal mol% C10:0 incorporation (56.1 mol%) occurred at a molar ratio of 1:6. An enzyme load of 10% gave the highest mol% C10:0 incorporation (41.4 mol%) in hexane; the highest incorporation (38.3 mol%) for the solvent‐free reaction occurred at 15% enzyme load. Mol% incorporation of C10:0 declined with increasing amounts of added water. The optimal mol% C10:0 incorporation occurred at 1% added water (47.9 mol%) for the reaction in hexane, and at zero added water for the solvent‐free reaction (21.8 mol%). Fish oil containing capric acid was successfully produced and may be nutritionally more beneficial than unmodified oil.
