Dual Frequency Comb Sampling of a Quasi-Thermal Incoherent Light Source (2010)

Dual, coherent frequency combs are used to measure the spectrum of an incoherent, quasi-thermal source through Fourier spectroscopy. The source spectrum is acquired over 1 THz bandwidth with an absolute frequency accuracy set by the combs.
Nutrient Analysis Methodology: A Review of the DINE Developmental Literature (1989)

In 1986, a collaborative effort among professional associations resulted in the publication of Worksite Nutrition: A Decision Maker's Guide (The American Diabetic Association, 1986). The booklet describes nutrient analysis methodology as a good "promotional gimmick". The development of DINE was an effort to move nutrient analysis from the gimmick level to a viable educational component level. A few examples of the innovative effects of this methodology are (1) individuals' using their own data can learn energy balance by monitoring their food intake and physical activity, (2) individuals can learn the Dietary Goals for the United States (U. S. Senate Select Subcommittee on Nutrition and Human Needs, 1977) and are able graphically to compare how their diet approximates or is different from these goals, and (3) individuals can also learn, from verifications of their own food records, which of their food selections were high in calories, total fat, saturated fat, and cholesterol, and low in complex carbohydrates and dietary fiber. Alternative healthful food choices are identified and the effects of reducing or increasing portion sizes is described. The DINE development team has been working for the past eight years to decrease nutrient analysis variability so that the procedure can be used as an effective independent measure to improve nutritional behavior. Research has been conducted related to database validity and reliability. Formative and process evaluations have been conducted to improve interactive aspects of the software and related manuals and books. DINE procedures have been modified for ease of use, in general, and specifically for elementary students and university students.
Implementing performance competitive logical recovery (2011)

New hardware platforms, e.g. cloud, multi-core, etc., have led to a reconsideration of database system architecture. Our Deuteronomy project separates transactional functionality from data management functionality, enabling a flexible response to exploiting new platforms. This separation requires, however, that recovery is described logically. In this paper, we extend current recovery methods to work in this logical setting. While this is straightforward in principle, performance is an issue. We show how ARIES style recovery optimizations can work for logical recovery where page information is not captured on the log. In side-by-side performance experiments using a common log, we compare logical recovery with a state-of-the art ARIES style recovery implementation and show that logical redo performance can be competitive.
Full-color reflective display system based on high contrast gratings (2014)

A full-color reflective display system with potentially unprecedented performances on brightness, color saturation, and contrast ratio is proposed. A three-layer architecture is employed to achieve maximum brightness, wherein the key components of every layer are reflective color filters based on high-contrast gratings that are designed and fabricated. The reflective filters exhibit both high reflectance and high color saturation. Switching of each color filter using electrowetting is proposed, and the feasibility of switching is proved. Finite-difference time-domain-based simulations are used in the design of the filters as well as to evaluate their performance. The fabrication process, which combines interference lithography, nanoimprint lithography, linewidth tuning, and reactive ion etching, is developed and optimized. The blue and the green filters are both fabricated and characterized experimentally.
Momentum Thickness Measurements for Thick Axisymmetric Turbulent Boundary Layers (2003)

Experimental measurements of the mean wall shear stress and boundary layer momentum thickness on long, thin cylindrical bodies are presented. To date, the spatial growth of the boundary layer and the related boundary layer parameters have not been measured for cases where δ/a (a=cylinder radius) is much greater than one. Moderate Reynolds numbers 104<Reθ<105 encountered in hydrodynamic applications are considered. Tow tests of cylinders with diameters of 0.61, 0.89, and 2.5 mm and lengths ranging from approximately 30 meters to 150 meters were performed. The total drag (axial force) was measured at tow speeds up to 17.4 m/sec. These data were used to determine the tangential drag coefficients on each test specimen, which were found to be two to three times greater than the values for the corresponding hypothetical flat-plate cases. Using the drag measurements, the turbulent boundary layer momentum thickness at the downstream end of the cylindrical bodies is determined, using a control volume analysis. The results show that for the smallest diameter cylinders, there is no indication of relaminarization, and a fully developed turbulent boundary layer exists. A scaling law for the momentum thickness versus length Reynolds number is determined from the data. The results indicate that the spatial growth of the boundary layers over the entire length is less than for a comparable flat-plate case.
Hematopoietic Transfer of the Anti-Cancer and Lifespan-Extending Capabilities of A Genetically Engineered Blood System (2023)

Abstract A causal relationship exists among the aging process, organ decay and dis-function, and the occurrence of various diseases including cancer. A genetically engineered mouse model, termed EklfK74R/K74R or Eklf(K74R), carrying mutation on the well-conserved sumoylation site of the hematopoietic transcription factor KLF1/ EKLF has been generated that possesses extended lifespan and healthy characteristics including cancer resistance. We show that the high anti-cancer capability of the Eklf(K74R) mice are gender-, age-and genetic background-independent. Significantly, the anti-cancer capability and extended lifespan characteristics of Eklf(K74R) mice could be transferred to wild-type mice via transplantation of their bone marrow mononuclear cells. Targeted/global gene expression profiling analysis has identified changes of the expression of specific proteins and cellular pathways in the leukocytes of the Eklf(K74R) that are in the directions of anti-cancer and/or anti-aging. This study demonstrates the feasibility of developing a novel hematopoietic/ blood system for long-term anti-cancer and, potentially, for anti-aging.
A Similarity Measure for Comparing XACML Policies (2012)

Assessing similarity of policies is crucial in a variety of scenarios, such as finding the cloud service providers which satisfy users' privacy concerns, or finding collaborators which have matching security and privacy settings. Existing approaches to policy similarity analysis are mainly based on logical reasoning and Boolean function comparison. Such approaches are computationally expensive and do not scale well for large heterogeneous distributed environments (like the cloud). In this paper, we propose a policy similarity measure as a lightweight ranking approach to help one party quickly locate parties with potentially similar policies. In particular, given a policy P, the similarity measure assigns a ranking (similarity score) to each policy compared with P. We formally define the measure by taking into account various factors and prove several important properties of the measure. Our extensive experimental study demonstrates the efficiency and practical value of our approach.
Spatial open-network formed by mixed triblock copolymers as a new medium for double-stranded DNA separation by capillary electrophoresis (2001)

A mixture of two polyoxybutylene-polyoxyethylene-polyoxybutylene (BEB) triblock copolymers (B6E46B6 and B10E271B10, respectively) was used as a new separation medium for separating double-stranded DNA (dsDNA) fragments by capillary electrophoresis (CE). The two block copolymer mixtures were designed to form mixed flower-like micelles in dilute solution and a homogeneous gel-like open-network with hydrophobic clusters as cross-linking points at higher polymer concentrations. Being a polyoxyalkylene block copolymer gel, the separation medium has some special advantages, including the temperature-dependent sol-gel transition that makes sample injection easy, and the self-coating of the inner capillary wall that makes experimental procedures simple and reproducible. Furthermore, it can shorten the elution time and further improve the separation resolution, especially for small dsDNA fragments, when compared with EPE-type separation media, e.g., F127 (E99P69E99, with P being polyoxypropylene) block copolymer gels formed by the closed packing of spherical micelles. Single base pair resolution can be achieved by using the new separation medium for dsDNA fragments up to over 100 base pairs.
Joint design of spoke trajectories and RF pulses for parallel excitation (2010)

The spoke trajectory is often used in designing multidimensional RF pulses for applications requiring thin slice selection and in-slice modulation. Ideally, a full set of spokes covering the whole k-space are desired to generate a given excitation pattern. In practice, however, only a small number of spokes can be used due to the RF pulse length limitation. The spoke locations are, therefore, critical to the performance of the resulting RF pulse and should be in principle optimized jointly with the RF pulse for a given excitation pattern and transmit sensitivities. In this work, we formulate the joint design problem as an optimal spoke selection problem based on the small-tip-angle RF pulse design. A sequential selection based algorithm with recursive cost function evaluation is proposed to seek optimized spoke locations to minimize the excitation error. Bloch equation simulations and experimental results on a 3 Tesla scanner equipped with a two-channel parallel excitation system demonstrate that the proposed method can produce significantly smaller excitation error than conventional methods with high computational efficiency.
A Solution of the Low-Speed Wheel Flutter Instability in Motorcycles (1976)

Motorcycles are subject to two dynamic steering instabilities, a low-speed ‘flutter’ at 6–8 Hz. and a high-speed ‘weave’ at 2-3 Hz, both of which are increased by adding a tail load, or by decreasing the rider mass. This paper is concerned with the low-speed instability, and describes work which resulted in the elimination of this potentially dangerous phenomenon from a current large-capacity motorcycle. The cause was found to be twofold: a fundamental castor instability at the front wheel, coupled to a resonance in the upper section of the main frame. Recommendations on future frame design are made, and fundamental limitations of the ‘telescopic’ front fork are demonstrated.

Inhibition of Prolactin Secretion by Ergolines (1974)

Peptide-containing ergot alkaloids and synthetic ergoline derivatives were administered to reserpine-treated male rats in order to evaluate their prolactin-inhibiting properties. Each compound was administered ip at a standard 50 ¼g/kg dose. The 9,10-dihydrogenated ergots, dihydroergocornine, and dihydroergocryptine were able to inhibit prolactin to the same degree as ergocornine and ergocryptine. This is significant because the 9,10-dihydrogenation process removes the toxic vasoconstrictive properties from the molecule and allows the prolactin-inhibiting ability to remain intact. In addition, dose-response studies show that minute amounts of an ergot can cause a significant reduction in prolactin secretion. The failure of ergocorninine to inhibit prolactin secretion demonstrates that the stereochemical configuration of the molecule at the 8 position is important for prolactin-inhibiting ability. Interestingly, a number of simple ergot molecules lacking the peptide side chain are able to inhibit prolactin secretion. Substitution at the 1 or 2 position as well as hydrogenation of the indole reduces the prolactin-inhibiting activity. The most active compound is D6-methyl-8βergolineacetonitrile. The high prolactin-inhibiting potency of these compounds suggests that they are able to mimic prolactin-inhibiting factor (PIF). (Endocrinology94: 1171, 1974)
JPEG2000-matched MRC compression of compound documents (2003)

The mixed raster content (MRC) ITU document compression standard (T.44) specifies a multilayer decomposition model for compound documents into two contone image layers and a binary mask layer for independent compression. While T.44 does not recommend any procedure for decomposition, it does specify a set of allowable layer codecs to be used after decomposition. While T.44 only allows older standardized codecs such as JPEG/JBIG/G3/G4, higher compression could be achieved if newer contone and bi-level compression standards such as JPEG2000/JBIG2 were used instead. We present an MRC compound document codec using JPEG2000 as the image layer codec and a layer decomposition scheme matched to JPEG2000 for efficient compression. JBIG still codes the mask. Noise removal routines enable efficient coding of scanned documents along with electronic ones. Resolution scalable decoding features are also implemented. The segmentation mask, obtained from layer decomposition, serves to separate text and other features.
Simultaneous Registration and Modeling of Deformable Shapes (2006)

Many natural objects vary the shapes as linear combinations of certain bases. The measurement of such deformable shapes is coupling of rigid similarity transformations between the objects and the measuring systems and non-rigid deformations controlled by the linear bases. Thus registration and modeling of deformable shapes are coupled problems, where registration is to compute the rigid transformations and modeling is to construct the linear bases. The previous methods [3, 2] separate the solution into two steps. The first step registers the measurements regarding the shapes as rigid and the deformations as random noise. The second step constructs the linear model using the registered shapes. Since the deformable shapes do not vary randomly but are constrained by the underlying model, such separate steps result in registration biased by nonrigid deformations and shape models involving improper rigid transformations. We for the first time present this bias problem and formulate that, the coupled registration and modeling problems are essentially a single factorization problem and thus require a simultaneous solution. We then propose the Direct Factorization method that extends a structure from motion method [16]. It yields a linear closedform solution that simultaneously registers the deformable shapes at arbitrary dimensions (2D \to 2D, 3D \to 3D, . . .) and constructs the linear bases. The accuracy and robustness of the proposed approach are demonstrated quantitatively on synthetic data and qualitatively on real shapes.
Synthesis and Characterization of Dimaleimide Fluorogens Designed for Specific Labeling of Proteins (2004)

A series of aromatic compounds were prepared bearing two maleimide groups attached directly to the fluorescent cores. The resulting derivatives do not fluoresce until the maleimide groups undergo their typical thiol addition reaction, thus removing their ability to quench fluorescence, as shown by kinetic and spectral characterization studies. In this way, the title compounds serve as fluorogens capable of detection of small thiols or appropriately sized dithiols. Recombinant alpha-helical proteins were then designed to bear two cysteine residues capable of regioselective dithiol addition reaction with the dimaleimide fluorogens, thus acting as spatially encoded substrates that form specifically labeled covalent complexes. The efficiency of this in vitro fluorescent protein-labeling reaction demonstrates the feasibility of the development of a method for the fluorescent labeling of specific recombinant proteins.
Crystalline cavities for quantum and nonlinear optics (2008)

Weakly-Supervised Degree of Eye-Closeness Estimation (2019)

Following recent technological advances there is a growing interest in building non-intrusive methods that help us communicate with computing devices. In this regard, accurate information from eye is a promising input medium between a user and computing devices. In this paper we propose a method that captures the degree of eye closeness. Although many methods exist for detection of eyelid openness, they are inherently unable to satisfactorily perform in real world applications. Detailed eye state estimation is more important, in extracting meaningful information, than estimating whether eyes are open or closed. However, learning reliable eye state estimator requires accurate annotations which is cost prohibitive. In this work, we leverage synthetic face images which can be generated via computer graphics rendering techniques and automatically annotated with different levels of eye openness. These synthesized training data images, however, have a domain shift from real-world data. To alleviate this issue, we propose a weakly-supervised method which utilizes the accurate annotation from the synthetic data set, to learn accurate degree of eye openness, and the weakly labeled (open or closed) real world eye data set to control the domain shift. We introduce a data set of 1.3M synthetic face images with detail eye openness and eye gaze information, and 21k real-world images with open/closed annotation. The dataset will be released online upon acceptance. Extensive experiments validate the effectiveness of the proposed approach.
Interlaboratory evaluation of an extraction and fluorescence method for the determination of trace beryllium in soils (2008)

Analytical methods for the determination of trace beryllium in soils are needed so that anthropogenic sources of this element can be distinguished from native (background) levels of beryllium. In this work, a collaborative interlaboratory evaluation of a new extraction and fluorescence-based procedure for determining beryllium in soil samples was carried out to fulfil method validation requirements for ASTM International voluntary consensus standard test methods. A Canadian reference material, CCRMP Till-1 soil, with a background beryllium concentration of 2.4 microg g(-1), was selected for study. This certified reference material (CRM) was spiked and homogenized with varying levels of beryllium oxide in order to give batches of material with beryllium concentrations of 4.36 +/- 0.69, 11.5 +/- 0.7, 124 +/- 7 and 246 +/- 16 microg g(-1) (+/- values are standard deviations). In the interlaboratory study (ILS), which was carried out in accordance with an applicable ASTM International standard practice (ASTM E691), samples of these spiked soils were subjected to extraction in dilute ammonium bifluoride at approximately 90 degrees C for 40 h. Fluorescence measurement of the extracted beryllium was carried out via detection using the high quantum yield fluorophore, hydroxybenzoquinoline sulfonate (HBQS). Interlaboratory precision estimates from six participating laboratories ranged from 0.048 to 0.103 (relative standard deviations) for the five different beryllium concentrations. Pooled bias estimates resulting from this ILS were between -0.049 and 0.177 for the various beryllium levels. These figures of merit support promulgation of the analytical procedure as an ASTM International standard test method.
Banding reduction in electrophotographic process (2002)

This paper proposes a new process control strategy for reducing banding artifacts in electrophotographic (EP) processes. EP banding artifact is shown to correlate to the fluctuation of the organic photoconductive (OPC) drum angular velocity. Improved regulation of the OPC drum rotational velocity under various process uncertainty and variations will significantly improve EP process stability and reduce the appearance of banding. The proposed control strategy includes two levels of OPC drum speed regulation. The first level, utilizes a loop shaping technique to incorporate a human visual system (HVS) model into the control loop to eliminate low frequency and non-periodic drum velocity fluctuation. The second level uses an internal model based repetitive controller to reduce the effect of periodic velocity fluctuations. The HVS based loop shaping design is intended to address the subjective evaluation of a printing process by incorporating human visual perception into EP process control. The experimental verification on a typical low cost 600-dpi EP engine showed significant banding reduction for spatial frequency up to 70 cycles per inch.
