Evaluation of Battery System for Frequency Control in Interconnected Power System with a Large Penetration of Wind Power Generation (2006)

Recently, a lot of distributed generations such as wind power generation are going to be installed into power systems. However, the fluctuation of these generator outputs affects the system frequency. Therefore, introduction of battery system to the power system has been considered in order to suppress the fluctuation of the total power output of the distributed generation. For frequency analysis, we use the interconnected 2-area power system model. It is assumed that a small control area with a large penetration of wind power plants is interconnected into a large control area. In this system, the tie line power fluctuation is very large as well as the system frequency fluctuation. It is shown that the installed battery can suppress these fluctuations and that the effect of battery on suppression of fluctuations depends on the battery capacity. Then, the required battery capacity for suppressing the tie line power deviation within a given level is calculated.
Spatial Deep Learning for Wireless Scheduling (2019)

The optimal scheduling of interfering links in a dense wireless network with full frequency reuse is a challenging task. The traditional method involves first estimating all the interfering channel strengths and then optimizing the scheduling based on the model. This model-based method is, however, resource intensive and computationally hard because channel estimation is expensive in dense networks; furthermore, finding even a locally optimal solution of the resulting optimization problem may be computationally complex. This paper shows that by using a deep learning approach, it is possible to bypass the channel estimation and to schedule links efficiently based solely on the geographic locations of the transmitters and the receivers due to the fact that in many propagation environments, the wireless channel strength is largely a function of the distance-dependent path-loss. This is accomplished by unsupervised training over randomly deployed networks and by using a novel neural network architecture that computes the geographic spatial convolutions of the interfering or interfered neighboring nodes along with subsequent multiple feedback stages to learn the optimum solution. The resulting neural network gives a near-optimal performance for sum-rate maximization and is capable of generalizing to larger deployment areas and to deployments of different link densities. Moreover, to provide fairness, this paper proposes a novel scheduling approach that utilizes the sum-rate optimal scheduling algorithm over judiciously chosen subsets of links for maximizing a proportional fairness objective over the network. The proposed approach shows highly competitive and generalizable network utility maximization results.
Fc-Glycosylation Influences Fcγ Receptor Binding and Cell-Mediated Anti-HIV Activity of Monoclonal Antibody 2G12 (2010)

Interactions between the Fc segment of IgG and FcγRs on a variety of cells are likely to play an important role in the anti-HIV activity of Abs. Because the nature of the glycan structure on the Fc domain is a critical determinant of Fc-FcγR binding, proper Fc glycosylation may contribute to Ab-mediated protection. We have generated five different glycoforms of the broadly HIV-1-neutralizing mAb 2G12 in wild-type and glycoengineered plants and Chinese hamster ovary cells. Plant-derived 2G12 exhibited highly homogeneous glycosylation profiles with a single dominant N-glycan species. Using flow cytometry with FcγR-expressing cell lines, all 2G12 glycoforms demonstrated similar binding to FcγRI, FcγRIIa, and FcγRIIb. In contrast, two glycoforms derived from glycoengineered plants that lack plant-specific xylose and core α1,3-fucose, and instead carry human-like glycosylation with great uniformity, showed significantly enhanced binding to FcγRIIIa compared with Chinese hamster ovary or wild-type plant-derived 2G12. Using surface plasmon resonance, we show that binding of 2G12 to FcγRIIIa is markedly affected by core fucose, irrespective of its plant-specific α1,3 or mammalian-type α1,6 linkage. Consistent with this finding, 2G12 glycoforms lacking core fucose (and xylose) mediated higher antiviral activity against HIV-1 or simian immunodeficiency virus as measured by Ab-dependent cell-mediated virus inhibition. This is, to our knowledge, the first demonstration that specific alterations of Fc glycosylation can improve antiviral activity. Such alterations may result in better immunotherapeutic reagents. Moreover, biasing vaccine-induced immune responses toward optimal Fc glycosylation patterns could result in improved vaccine efficacy.
Demodulation of Feedback Signal for Wireless Charging Systems According to the Qi Standard (2018)

In wireless device charging systems according to the Wireless Power Consortium's Qi standard communication from the power receiver to the power transmitter is required. Communication signal is modulated to the power signal with the backscatter modulation. This article presents the problems which arise in implementation of a demodulation of this signal on an ARM microprocessor, the STM32F407VG is used here. Appropriate measures provide minimum number of transfer errors and communication packet loss. A programming code implementation with a fast loop for signal processing and a slow loop for packet identification is proposed. It can be used in the development of devices for wireless charging, according to the Qi standard.
FEHash: Full Entropy Hash for Face Template Protection (2020)

In this paper, we present a hashing function for the application of face template protection, which improves the correctness of existing algorithms while maintaining the security simultaneously. The novel architecture constructed based on four components: a self-defined concept called padding people, Random Fourier Features, Support Vector Machine, and Locality Sensitive Hashing. The proposed method is trained, with one-shot and multi-shot enrollment, to encode the user's biometric data to a predefined output with high probability. The predefined hashing output is cryptographically hashed and stored as a secure face template. Predesigning outputs ensures the strict requirements of biometric cryptosystems, namely, randomness and unlinkability. We prove that our method reaches the REQ-WBP (Weak Biometric Privacy) security level, which implies irreversibility. The efficacy of our approach is evaluated on the widely used CMU-PIE, FEI, andFERET databases; our matching performances achieve 100% genuine acceptance rate at 0% false acceptance rate for all three databases and enrollment types. To our knowledge, our matching results outperform most of state-of-the-art results.

Gut microbiota and host metabolism in liver cirrhosis (2015)

The gut microbiota has the capacity to produce a diverse range of compounds that play a major role in regulating the activity of distal organs and the liver is strategically positioned downstream of the gut. Gut microbiota linked compounds such as short chain fatty acids, bile acids, choline metabolites, indole derivatives, vitamins, polyamines, lipids, neurotransmitters and neuroactive compounds, and hypothalamic-pituitary-adrenal axis hormones have many biological functions. This review focuses on the gut microbiota and host metabolism in liver cirrhosis. Dysbiosis in liver cirrhosis causes serious complications, such as bacteremia and hepatic encephalopathy, accompanied by small intestinal bacterial overgrowth and increased intestinal permeability. Gut dysbiosis in cirrhosis and intervention with probiotics and synbiotics in a clinical setting is reviewed and evaluated. Recent studies have revealed the relationship between gut microbiota and host metabolism in chronic metabolic liver disease, especially, non-alcoholic fatty liver disease, alcoholic liver disease, and with the gut microbiota metabolic interactions in dysbiosis related metabolic diseases such as diabetes and obesity. Recently, our understanding of the relationship between the gut and liver and how this regulates systemic metabolic changes in liver cirrhosis has increased. The serum lipid levels of phospholipids, free fatty acids, polyunsaturated fatty acids, especially, eicosapentaenoic acid, arachidonic acid, and docosahexaenoic acid have significant correlations with specific fecal flora in liver cirrhosis. Many clinical and experimental reports support the relationship between fatty acid metabolism and gut-microbiota. Various blood metabolome such as cytokines, amino acids, and vitamins are correlated with gut microbiota in probiotics-treated liver cirrhosis patients. The future evaluation of the gut-microbiota-liver metabolic network and the intervention of these relationships using probiotics, synbiotics, and prebiotics, with sufficient nutrition could aid the development of treatments and prevention for liver cirrhosis patients.
Persistent homology: an introduction and a new text representation for natural language processing (2013)

Persistent homology is a mathematical tool from topological data analysis. It performs multi-scale analysis on a set of points and identifies clusters, holes, and voids therein. These latter topological structures complement standard feature representations, making persistent homology an attractive feature extractor for artificial intelligence. Research on persistent homology for AI is in its infancy, and is currently hindered by two issues: the lack of an accessible introduction to AI researchers, and the paucity of applications. In response, the first part of this paper presents a tutorial on persistent homology specifically aimed at a broader audience without sacrificing mathematical rigor. The second part contains one of the first applications of persistent homology to natural language processing. Specifically, our Similarity Filtration with Time Skeleton (SIFTS) algorithm identifies holes that can be interpreted as semantic tie-backs in a text document, providing a new document structure representation. We illustrate our algorithm on documents ranging from nursery rhymes to novels, and on a corpus with child and adolescent writings.
Scalable Learning-Based Sampling Optimization for Compressive Dynamic MRI (2020)

Compressed sensing applied to magnetic resonance imaging (MRI) allows to reduce the scanning time by enabling images to be reconstructed from highly undersampled data. In this paper, we tackle the problem of designing a sampling mask for an arbitrary reconstruction method and a limited acquisition budget. Namely, we look for an optimal probability distribution from which a mask with a fixed cardinality is drawn. We demonstrate that this problem admits a compactly supported solution, which leads to a deterministic optimal sampling mask. We then propose a stochastic greedy algorithm that (i) provides an approximate solution to this problem, and (ii) resolves the scaling issues of [1], [2]. We validate its performance on in vivo dynamic MRI with retrospective undersampling, showing that our method preserves the performance of [1], [2] while reducing the computational burden by a factor close to 200. Our implementation is available at https://github.com/t-sanchez/stochasticGreedyMRI.
A Highly Desensitized, Wide-Band Monolithic Amplifier (1966)

An all-diffused monolithic feedback triple with a maximum bandwidth of 50 MHz, 40 dB of feedback, and gain adjustable from 34 dB to 52 dB is described. Harmonic distortion is less than 0.15 percent at 0.5 MHz and gain variation is less than /spl plsmn/0.25 dB from -55/spl deg/C to +125/spl deg/C. Detailed analysis of the amplifier performance is carried out and an accurate design technique based upon transistor models is developed. A distributed base model is introduced which results in prediction of open loop gain and phase to within 10 percent of measured values at all frequencies below 200 Mc/s.
mTOR-regulated senescence and autophagy during reprogramming of somatic cells to pluripotency: A roadmap from energy metabolism to stem cell renewal and aging (2011)

Molecular controllers of the number and function of tissue stem cells may share common regulatory pathways for the nuclear reprogramming of somatic cells to become induced Pluripotent Stem Cells (iPSCs). If this hypothesis is true, testing the ability of longevity-promoting chemicals to improve reprogramming efficiency may provide a proof-of-concept validation tool for pivotal housekeeping pathways that limit the numerical and/or functional decline of adult stem cells. Reprogramming is a slow, stochastic process due to the complex and apparently unrelated cellular processes that are involved. First, forced expression of the Yamanaka cocktail of stemness factors, OSKM, is a stressful process that activates apoptosis and cellular senescence, which are the two primary barriers to cancer development and somatic reprogramming. Second, the a priori energetic infrastructure of somatic cells appears to be a crucial stochastic feature for optimal successful routing to pluripotency. If longevity-promoting compounds can ablate the drivers and effectors of cellular senescence while concurrently enhancing a bioenergetic shift from somatic oxidative mitochondria toward an alternative ATP-generating glycolytic metabotype, they could maximize the efficiency of somatic reprogramming to pluripotency. Support for this hypothesis is evidenced by recent findings that well-characterized mTOR inhibitors and autophagy activators (e.g., PP242, rapamycin and resveratrol) notably improve the speed and efficiency of iPSC generation. This article reviews the existing research evidence that the most established mTOR inhibitors can notably decelerate the cellular senescence that is imposed by DNA damage-like responses, which are somewhat equivalent to the responses caused by reprogramming factors. These data suggest that fine-tuning mTOR signaling can impact mitochondrial dynamics to segregate mitochondria that are destined for clearance through autophagy, which results in the loss of mitochondrial function and in the accelerated onset of the glycolytic metabolism that is required to fuel reprogramming. By critically exploring how mTOR-regulated senescence, bioenergetic infrastructure and autophagy can actively drive the reprogramming of somatic cells to pluripotency, we define a metabolic roadmap that may be helpful for designing pharmacological and behavioral interventions to prevent or retard the dysfunction/exhaustion of aging stem cell populations.
Precise blood flow imaging in ultrasonic power Doppler imaging based on motion compensation (2010)

A novel method of motion compensated power Doppler imaging (MC-PDI) has been investigated and found to improve the spatial and contrast resolution of ultrasonic power Doppler imaging (PDI), which is widely used to visualize blood flow velocity. The tissue motion in neighboring frames sequentially obtained is measured with a block matching technique, and then several power Doppler (PD) images are averaged compensating for deviation in the tissue. Image quality with and without motion compensation (MC) was quantitatively evaluated using a Doppler phantom. The feasibility of MC-PDI was demonstrated using a tumor in rabbit liver. The resulting images indicated that slight liver motion could be effectively reduced and the blood vessels could be clearly imaged without blurring in MC-PDI.
A CDMA-based radio access design for UMTS (1995)

The major challenge for the CODIT (code division testbed) project is to design a concept that can support a range of new services with a bit range of up to 2 Mb/s. The concept must be flexible enough to meet the requirements of future services envisioned for UMTS. The required task of the project is to investigate a concept based on spread spectrum techniques. The system that is being developed in the project is based on direct sequence CDMA. New innovative techniques are being developed in the project, where the solutions go far beyond the CDMA concepts proposed for second generation systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Experimental study on optimization parameters of a supersonic jet ejector thrust augmentor. (1973)

The experimental data were aimed at obtaining the effect of jet mixing, the effective length/diameter of the ejector tube, the entrance length shape factor, the shape loading, and the optimum primary jet location. The total augmented thrust is proportional to the diameter of the ejector. The data show that for a practical design the entrance lip shape and the stream lines around the lip are also important in order to optimize the percentage augmentation.
Optical Modes in Two-dimensionally Ordered Dielectric Spheres (2000)

We have experimentally observed the optical modes of periodic two-dimensionally ordered polystyrene spheres with a diameter of 5.15 µm using the attenuated total reflection method. The dispersion relation of such optical modes clearly shows that there are two types of propagating modes in the ordered spheres. We point out that one of the two optical modes is related to the guided modes in optical fibers and the periodicity of the spheres plays an important role in its excitation mechanism. The other mode propagates along spherical surfaces.
InP DHBT Very High Speed Power-DACs for Spectrally Efficient Optical Transmission Systems (2011)

This paper reports on very high speed large swing digital-to-analog converter (DAC) suiting the generation of spectrally efficient optical transmission signals. 2-bit and 3-bit DACS with up to 4 Vpp swing, operating up to 50 GBaud, have been fabricated using our InP DHBT technology (F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> ~280 GHz, F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MAX</sub> ~270 GHz, BV <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CE0</sub> ~5 V).

Impact of 2-Methyl-2-Adamantyl Group Used for 193-nm Single-Layer Resist (1996)

To use a TMAH (tetramethylanmonium hydroxide aqueous solution) developer with a resist based on adamantylmethacrylates, we proposed a cleavable adamantyl ester by protonic acid. We found that a 2-methyl-2-adamantyl ester was cleavable by protonic acid and poly(2MAdMA) (2-methyl-2-adamantylmethacrylate) worked as a chemically amplified resist with good sensitivity. We achieved high resolution by improving the adhesion. The 2MAdMA-MAA (methacrylic acid) resist achieved 0.165μm L/S with 3.0mJ/cm2 in ArF evaluation using a dilute TMAH developer. We could use a 2.38% TMAH developer by introducing 2MAdMA to the strongly polar acid labile protect group, OCMA (3-oxocyclohecylmethacrylate) or MLMA (mevalonic lactone methacrylate), which had good adhesion. We obtained fine patterns below 0.20μm at below 10mJ/cm2 in ArF evaluation with 2.38%TMAH developer. We achieved a minimum resolution with 0.15 pm L/S patterns and a D.O.FE of 0.6pm at 0.18μm L/S patterns using a 2MAdMA-MLMA resist.
Synthesis and characterisation of methine dyes derived from condensation of 4‐nitrophenylacetonitrile with aromatic aldehydes (2004)

A range of methine dyes has been synthesised by condensation of electronegative active methylene compound, 4‐nitrophenylacetonitrile with substituted benzaldehydes. The electronic absorption spectroscopic properties of the dyes were investigated. It was found that in general, substituents on the aromatic aldehyde moiety had a significant effect on the visible absorption maxima of the dyes.
Determination and optimization of mode matching into optical cavities by heterodyne detection (2000)

We report on a novel high-sensitivity method to characterize and improve mode matching into optical cavities. This method is based on heterodyne detection of cylindrical transverse cavity modes. A specially designed annular-segmented photodiode is used to measure the amplitude of nonresonant modes reflected by the cavity. Our measurements allow us to optimize cavity mode matching to nearly 99.98% and will play an important diagnostic role in gravitational-wave detectors.
<title>Generalized hit-miss operators</title> (1990)

The morphological operations of a hit-miss transform opening and closing are generalized in a number of ways. The new operations have been applied to a variety of binary image analysis problems that involve pattern detection and reconstruction. Generalized openings are developed by replacing erosions with hit-miss transforms. These new openings are shown to be anti-extensive idempotent and center-independent. Similarly generalized closings are developed and related to openings by duality. Additionally the hit-miss transform is further generalized by replacing the erosions with blur and rank order transforms in order to improve the robustness of pattern matches. The set of invariance properties of these new transforms can be widened by forming generalized openings from them.
Collective Synthesis and Biological Evaluation of Tryptophan‐Based Dimeric Diketopiperazine Alkaloids (2015)

A concise two one-pot synthesis of WIN 64821, eurocristatine, 15,15'-bis-epi-eurocristatine, ditryptophenaline, ditryptoleucine A, WIN 64745, cristatumin C, asperdimin, naseseazine A, and naseseazine B is detailed, based on a unique bioinspired dimerization reaction of tryptophan derivatives in aqueous acidic solution and a one-pot procedure for the construction of diketopiperazine rings. Total yields of these alkaloid syntheses were from 10 up to 27 %. In addition, 1'-(2-phenylethylene)-ditryptophenaline was synthesized by using three one-pot operations. The studies detailed herein provided synthesized natural products for inhibitory activities of ubiquitin-specific protease 7 (USP7) and foam cell formation in macrophages. The newly listed biological evaluation for tryptophan-based dimeric diketopiperazine alkaloids discovered 15,15'-bis-epi-eurocristatine, 1'-(2-phenylethylene)-ditryptophenaline, and WIN 64745 as new drug candidates.
