Acoustic Detection of Imminent Blowout in Pilot and Swirl Stabilized Combustors (2003)

This paper describes an experimental effort to characterize the acoustic emissions of lean, premixed combustors operating near blowout conditions. Its objective is to use measurements of the flame’s acoustic signature to determine the proximity of the combustor to incipient blowout. The feasibility of the method was performed on two combustors with fundamentally different flame holding methods: externally anchored pilot and swirl-stabilized. Acoustic measurements indicate that the low frequency spectrum exhibits a strong dependence upon the degree of flame stabilization. High speed intensified camera images of the flame were also taken to get a better understanding of the unsteady flame dynamics. In the piloted burner, it became visibly obvious that the flame was approaching blowoff by increased flickering, unsteadiness, and non-symmetric flame attachment. The results from the swirl burner, however, show that the blow-off transient was characterized by short duration, localized extinction and re-ignition events. These events increase in frequency and duration as blowout is approached. Several data analysis approaches using spectral, statistical and wavelet techniques with varying degrees of sensitivity are shown to be capable of detecting precursors to blowout for both burners.
Cost-optimized design of flexible-grid optical networks considering regenerator site selection (2013)

In this paper, we aim to minimize the total network cost in flexible-grid optical networks with multiple line rates. Besides transponder cost, regenerator cost, and shared infrastructure cost, the cost of regenerator sites is also considered. We first provide the problem definition and formulate the problem as an integer linear program (ILP). We also propose a heuristic algorithm considering both selection and placement of equipment to minimize the total network cost. Simulation results show the heuristic algorithm results in up to 28% cost saving, with no significant increase in spectrum usage.
Joint Utility and Frequency for Pattern Classification (2021)

High-frequency itemset mining (HFIM) and high-utility itemset mining (HUIM) aim to discover itemsets with high occurrence and high utility, respectively, in a transaction database. A number of efficient algorithms have been developed to identify these high-utility itemsets (HUIs) or high-frequency itemsets (HFIs). Such algorithms play an increasingly important role in many occasions especially for analysis in commercial enterprises. In this paper, we propose a new model called joint utility and frequency for pattern classification, and two new algorithms, namely UFC <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gen</inf> and UFC <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">fast</inf> . Both algorithms are designed to categorize each itemset into different type of patterns by setting the minimum thresholds of utility and frequency. We compare these algorithms on two datasets. The experimental results show that both algorithms can successfully collect three different types of itemsets from all candidate itemsets based on frequency and utility, and the list-based UFC <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">fast</inf> algorithm outperforms the level-wise-based UFC <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gen</inf> algorithm in terms of execution time.

Video-based face recognition using probabilistic appearance manifolds (2003)

This paper presents a method to model and recognize human faces in video sequences. Each registered person is represented by a low-dimensional appearance manifold in the ambient image space, the complex nonlinear appearance manifold expressed as a collection of subsets (named pose manifolds), and the connectivity among them. Each pose manifold is approximated by an affine plane. To construct this representation, exemplars are sampled from videos, and these exemplars are clustered with a K-means algorithm; each cluster is represented as a plane computed through principal component analysis (PCA). The connectivity between the pose manifolds encodes the transition probability between images in each of the pose manifold and is learned from a training video sequences. A maximum a posteriori formulation is presented for face recognition in test video sequences by integrating the likelihood that the input image comes from a particular pose manifold and the transition probability to this pose manifold from the previous frame. To recognize faces with partial occlusion, we introduce a weight mask into the process. Extensive experiments demonstrate that the proposed algorithm outperforms existing frame-based face recognition methods with temporal voting schemes.
Development of a {111} Recrystallization Texture Associated WithDynamic Strain Aging During Hot Rolling in the Ferrite Region (1993)

Hot rolling in the ferrite region is applied in an extra‐low C sheet steel without cold rolling by employing dynamic strain aging. When the amount of solute C is about 10 ppm before rolling, the r‐value and {222} intensity ratio of sheet steel annealed after rolling are maxima at the rolling temperature of 773K, during which dynamic strain aging occurs. The {222} residual strain in the specimen rolled at 773K is higher than that in specimens rolled at other temperatures. It is proposed that dynamic strain aging would provide high stored energy in the {111} component of an as‐rolled specimen, with the result that the region of high stored energy would recover and nucleate rapidly so that a strong {111} recrystallization texture develops.
In Vitro Cellular Immune Responses to Recombinant Antigens of<i>Mycobacterium avium</i>subsp.<i>paratuberculosis</i> (2005)

Five recombinant antigens (Ags; 85A, 85B, 85C, superoxide dismutase [SOD], and 35-kDa protein) were purified from Mycobacterium avium subsp. paratuberculosis and evaluated for their ability to stimulate peripheral blood mononuclear cells (PMBCs) from fecal-culture-positive cows (low and medium shedders) and culture-negative healthy cows. Recombinant Ags 85A, 85B, and 85C induced significant lymphocyte proliferation as well as the production of gamma interferon (IFN-gamma), interleukin-2 (IL-2), IL-12, and tumor necrosis factor alpha (TNF-alpha), but not IL-4, from low and medium shedders. The 85 antigen complex did not stimulate PMBC proliferation from culture-negative healthy cows. The 35-kDa protein also induced significant lymphocyte proliferation as well as the production of IFN-gamma and IL-4 from low and medium shedders. CD4(+) T cells and CD25(+) (IL-2R) T cells were stimulated the most by 85A and 85B, while the 35-kDa protein primarily stimulated CD21(+) B cells involved in humoral immune responses. Interestingly, SOD was less immunostimulatory than other antigens but strongly induced gammadelta(+) T cells, which are thought to be important in the early stages of infection, such as pathogen entry. These data provide important insight into how improved vaccines against mycobacterial infections might be constructed.
Adversarial Learning in Statistical Classification: A Comprehensive Review of Defenses Against Attacks (2019)

There is great potential for damage from adversarial learning (AL) attacks on machine-learning based systems. In this paper, we provide a contemporary survey of AL, focused particularly on defenses against attacks on statistical classifiers. After introducing relevant terminology and the goals and range of possible knowledge of both attackers and defenders, we survey recent work on test-time evasion (TTE), data poisoning (DP), and reverse engineering (RE) attacks and particularly defenses against same. In so doing, we distinguish robust classification from anomaly detection (AD), unsupervised from supervised, and statistical hypothesis-based defenses from ones that do not have an explicit null (no attack) hypothesis; we identify the hyperparameters a particular method requires, its computational complexity, as well as the performance measures on which it was evaluated and the obtained quality. We then dig deeper, providing novel insights that challenge conventional AL wisdom and that target unresolved issues, including: 1) robust classification versus AD as a defense strategy; 2) the belief that attack success increases with attack strength, which ignores susceptibility to AD; 3) small perturbations for test-time evasion attacks: a fallacy or a requirement?; 4) validity of the universal assumption that a TTE attacker knows the ground-truth class for the example to be attacked; 5) black, grey, or white box attacks as the standard for defense evaluation; 6) susceptibility of query-based RE to an AD defense. We also discuss attacks on the privacy of training data. We then present benchmark comparisons of several defenses against TTE, RE, and backdoor DP attacks on images. The paper concludes with a discussion of future work.
Comparison of Growth of Campylobacteriaceae on Media Supplemented with Organic Acids and on Commercially Available Media (2006)

Experiments were conducted to compare the ability of a medium supplemented with organic acids to the ability of commercially available, non-selective media to support growth of Campylobacter spp. and Arcobacter butzleri. Liquid medium was composed of yeast extract-peptone basal broth (BB) that could be supplemented with an organic acid (OA) mixture of fumaric, lactic, malic, and succinic acids (BB + OA). Growth of cultures in BB and in BB + OA was compared to growth in Brucella broth, Mueller-Hinton broth, and Fluid Thioglycollate medium. Growth of A. butzleri and 10 of 15 Campylobacter isolates was significantly (P < 0.05) greater in BB + OA than in other broth media, while there was no significant difference in growth of the other 5 Campylobacter isolates in BB, BB + OA, Brucella broth, Mueller-Hinton broth, or Fluid Thioglycollate medium. Growth was also compared on agar media composed of BB + OA with Bacto agar and hemin (BA-hemin + OA) and on Remel Blood Agar. Results indicated that there was no significant ® difference in the number of cfu’s recovered on BA-hemin + OA and on blood agar. Findings indicate that media supplemented with organic acids may be used as alternatives to some currently available commercial media for growing and maintaining Campylobacteriaceae.
Sulfolane-Cross-Polybenzimidazole Membrane For Gas Separation (2006)

A cross-linked, supported polybenzimidazole membrane for gas separation is prepared by reacting polybenzimidazole (PBI) with the sulfone-containing crosslinking agent 3,4-dichloro-tetrahydro-thiophene-1,1-dioxide. The cross-linked reaction product exhibits enhanced gas permeability to hydrogen, carbon dioxide, nitrogen, and methane as compared to the unmodified analog, without significant loss of selectivity, at temperatures from about 20 degrees Celsius to about 400 degrees Celsius.
Easy access to efficient magnetically recyclable separation of histidine-tagged proteins using superparamagnetic nickel ferrite nanoparticle clusters (2011)

The simple and efficient separation of histidine-tagged (His-tagged) proteins using nickel ferrite (NiFe2O4) nanoparticle clusters (NPCs) is described in this article. While nanostructured materials containing Ni2+ ions for efficient separation were generally synthesized via complex synthetic procedures, the NiFe2O4 nanoparticle clusters used in this work were simply synthesized by a one-pot hydrothermal polyol process. Their large surface area (105.0 m2 g−1) and pore volume (0.32 cm3 g−1) provide sufficient sites for the separation of His-tagged proteins. The high magnetic saturation value (41.3 emu g−1) and superparamagnetic property of these nanoparticle clusters lead to a more efficient magnetically recyclable separation of His-tagged proteins. We confirmed that the binding capacity and selective separation ability seen in the first separation were strongly maintained for up to 7 cycles.
A novel fabrication process of a silicon field emitter array with thermal oxide as a gate insulator (1995)

We have successfully developed a fabrication process of a silicon field emitter array with a gate insulator formed by Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> sidewall formation and subsequent thermal oxidation. This process overcomes some problems in the conventional fabrication, such as high etch rate, low breakdown field, and gate hole expansion arising from evaporation of gate oxide. Therefore, we could improve process stability and emission performance, and also reduce gate leakage current. The optimum process conditions were determined by process simulations using SUPREM-4. The turn-on voltage of the fabricated field emitters was approximately 38 V. An anode current of 0.1 μA (1 μA) per tip was measured for a 625-tip array at the gate bias of 80 V (100 V), and the gate current was less than 0.3% of the anode current at those emission levels.
Photo-Spectrometer Realized In A Standard Cmos Ic Process (1999)

A spectrometer, comprises: a semiconductor having a silicon substrate, the substrate having integrally formed thereon a plurality of layers forming photo diodes, each of the photo diodes having an independent spectral response to an input spectra within a spectral range of the semiconductor and each of the photo diodes formed only from at least one of the plurality of layers of the semiconductor above the substrate; and, a signal processing circuit for modifying signals from the photo diodes with respective weights, the weighted signals being representative of a specific spectral response. The photo diodes have different junction depths and different polycrystalline silicon and oxide coverings. The signal processing circuit applies the respective weights and sums the weighted signals. In a corresponding method, a spectrometer is manufactured by manipulating only the standard masks, materials and fabrication steps of standard semiconductor processing, and integrating the spectrometer with a signal processing circuit.
Abstract 1484: Aldose reductase inhibition prevents breast cancer cell growth and restores breast cancer cell hormone dependency (2010)

Abstract Breast Cancer (BC) is the second leading cause of cancer deaths in the U.S. women. Hormone ablation therapy reduces the risk of cancer recurrence and improves the survival rate of most BC patients. Although BC initially responds to estrogen ablation therapy, as the cancer progresses, the cancer cells become hormone-independent and prone to metastasis, a major cause of mortality in BC patients. The few currently available drugs that restore hormone dependence are only partially effective and prohibitively costly. Hence there is an urgent need for novel therapeutic modalities. We have recently shown that aldose reductase (AR)-catalyzed GSH-lipid aldehyde conjugates such as GS-DHN induces growth factors-, cytokines- and chemokines-mediated signals that activate PKC, PLC and PI3K, which regulate transcription of NF-κB- and AP1-dependent inflammatory markers. Further, AR has been shown to be overexpressed in human breast cancers. We have investigated the efficacy of AR inhibition in preventing BC cells growth and reversing hormone dependency of BC cells. Our results indicate that pharmacological inhibition of AR or siRNA ablation of AR prevents growth factor -induced proliferation of BC cells (MCF-7) in culture. Similar results were observed when MDA-MB-231 and MDA-MB-468 BC cells were used. To further investigate how AR inhibitor prevents BC cell growth, we have examined the role of AR in resensitization of BC cells to letrozole. We found that combination of fidarestat with letrozole was very effective in inducing maximum cell death in LTLT-Ca cells when compared to fidarestat alone. The combination treatment not only restored estrogen receptor-α (ER-α) levels but also down-regulated HER2/MAPK-signaling proteins. Further, AR-siRNA - transfected MCF-7/Aro and MCF-7 cells upregulated ER-α in western blot and ER-functionality assays whereas in LTLT-Ca cells, ER-α levels were down-regulated as in fidarestat treated cells. Targeting the LTLT-Ca cells with PLG-based fidarestat nanoparticles having polyethylene glycol (PEG)-5000 as stabilizer and conjugated with FITC significantly prevented the aromatase activity in BC cells. Thus we have identified a novel role of AR in BC cell growth and estrogen-dependence of hormone insensitive BC cells and suggest the use of AR inhibitors either alone or in combination with letrozole to prevent as well as treat BC.

Sparse coding for super-resolution via K-means classification (2017)

Super-resolution techniques reconstructing a higher resolution image from one or multiple low-resolution images are helpful to visual recognition under the scenarios of insufficient acquisition resolution. Due to the limited wireless network transmission bandwidth or mobile device processing capacity, image resolution in mobile phones and other mobile devices is not as high as expected, which restricts the clarity of the image display. This kind of resolution-improvement technique shows a great value for the mobile business. wing to the graceful theoretical foundation, image super-resolution methods via sparse coding have gained much popularity since it was proposed in 2008. However, the underlying single sparse dictionary in the existing methods is difficult to adapt to complex and diversified image contents so that the promotion of representation precision heavily depends on the growth of dictionary volume. In this paper, we propose to learn a set of coupled-dictionaries corresponding to unequal content complexity by using K-means classification, and then adaptively choose an appropriate one for each input low-resolution patch during super-resolution reconstruction. The experimental results on public dataset show that our approach outperforms the classic sparse coding based methods in terms of visual effects and PSNR metrics.

A new suspension and guidance configuration for a high speed, electrodynamic suspension (EDS) maglev system is discussed. The configuration can also be used to develop an electromagnetic guideway directional switch. The performance of the system is predicted using the dynamic circuit model. General expressions of the magnetic forces based on the harmonic approximation are obtained. The principle of the electromagnetic guideway directional switch for the EDS maglev system is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Planar flexible fiber-optic interferometric acoustic sensor (1988)

A planar flexible fiber-optic interferometric acoustic sensor has been developed by wrapping optimized single-mode fibers in a planar spiral form and then embedding the fiber in a thin polyurethane layer. Both the acoustic and the acceleration responses have been found to compare favorably with those of a planar polyvinylidene fluoride sensor of similar geometry.
The inherent difficulty of timely primary-backup replication (2011)

We show that existing methods for primary-backup replication may disrupt the timing behavior of an underlying service to the extent of making it unusable. We prove that the problem is inherent to the primary-backup model.
Capturing and stylizing hair for 3D fabrication (2014)

Recently, we have seen a growing trend in the design and fabrication of personalized figurines, created by scanning real people and then physically reproducing miniature statues with 3D printers. This is currently a hot topic both in academia and industry, and the printed figurines are gaining more and more realism, especially with state-of-the-art facial scanning technology improving. However, current systems all contain the same limitation - no previous method is able to suitably capture personalized hair-styles for physical reproduction. Typically, the subject's hair is approximated very coarsely or replaced completely with a template model. In this paper we present the first method for stylized hair capture, a technique to reconstruct an individual's actual hair-style in a manner suitable for physical reproduction. Inspired by centuries-old artistic sculptures, our method generates hair as a closed-manifold surface, yet contains the structural and color elements stylized in a way that captures the defining characteristics of the hair-style. The key to our approach is a novel multi-view stylization algorithm, which extends feature-preserving color filtering from 2D images to irregular manifolds in 3D, and introduces abstract geometric details that are coherent with the color stylization. The proposed technique fits naturally in traditional pipelines for figurine reproduction, and we demonstrate the robustness and versatility of our approach by capturing several subjects with widely varying hair-styles.
