REIT-Based Property Return Indices: <i>A New Way to Track and Trade Commercial Real Estate</i> (2009)

Using REIT return data, bond data, and property holding data, the authors construct property market segment-specific indices of asset returns. The authors show that these <i>pure-play</i> indices can be employed to make pure, targeted investments in the commercial real estate market while retaining the liquidity, transparency, and pricing efficiency benefits of the well-developed public market in REITs. These pure-play indices compare favorably with existing property market return indices, displaying volatilities similar to transaction-based indices, such as the Moody’s/REAL Commercial Property Price Index, but tending to lead the private market in time. The pure-play indices can be generated at a daily frequency without significant noise and at various levels of market segment granularity and, notably, have led the transactions-based direct property market indices during the recent market downturn. The authors’ findings suggest that the REIT-based pure-play indices may provide a unique, new information source about the commercial property market, as well as a unique capability to facilitate targeted investments, construct hedges, and potentially support derivatives trading. <b>TOPICS:</b>In markets, real estate, options
Simultaneous, Full-Surface Visualizations of Transition and Separation Using Liquid Crystal Coatings (1997)

To capitalize the unique shear-direction-indicating capabilities of liquid crystal coatings, two opposing-view, synchronized, color video cameras need to be deployed: one with an oblique, downstream-facing view of the test surface and the other with an oblique, upstream-facing view. Present understanding dictates that the test surface be planarlike, i.e., no regions of extreme curvature, and that it be uniformly illuminated from above.
Multimodal Perception of Histological Images for Persons Who Are Blind or Visually Impaired (2017)

Lack of suitable substitute assistive technology is a roadblock for students and scientists who are blind or visually impaired (BVI) from advancing in careers in science, technology, engineering, and mathematics (STEM) fields. It is challenging for persons who are BVI to interpret real-time visual scientific data which is commonly generated during lab experimentation, such as performing light microscopy, spectrometry, and observing chemical reactions. To address this problem, a real-time multimodal image perception system was developed to allow standard laboratory blood smear images to be perceived by BVI individuals by employing a combination of auditory, haptic, and vibrotactile feedback. These sensory feedback modalities were used to convey visual information through alternative perceptual channels, thus creating a palette of multimodal, sensory information. Two sets of image features of interest (primary and peripheral features) were applied to characterize images. A Bayesian network was applied to construct causal relations between these two groups of features. In order to match primary features with sensor modalities, two methods were conceived. Experimental results confirmed that this real-time approach produced higher accuracy in recognizing and analyzing objects within images compared to conventional tactile images.
Human-Aware Motion Deblurring (2019)

This paper proposes a human-aware deblurring model that disentangles the motion blur between foreground (FG) humans and background (BG). The proposed model is based on a triple-branch encoder-decoder architecture. The first two branches are learned for sharpening FG humans and BG details, respectively; while the third one produces global, harmonious results by comprehensively fusing multi-scale deblurring information from the two domains. The proposed model is further endowed with a supervised, human-aware attention mechanism in an end-to-end fashion. It learns a soft mask that encodes FG human information and explicitly drives the FG/BG decoder-branches to focus on their specific domains. Above designs lead to a fully differentiable motion deblurring network, which can be trained end-to-end. To further benefit the research towards Human-aware Image Deblurring, we introduce a large-scale dataset, named HIDE, which consists of 8,422 blurry and sharp image pairs with 65,784 densely annotated FG human bounding boxes. HIDE is specifically built to span a broad range of scenes, human object sizes, motion patterns, and background complexities. Extensive experiments on public benchmarks and our dataset demonstrate that our model performs favorably against the state-of-the-art motion deblurring methods, especially in capturing semantic details.
Current-Induced Domain Wall Motion in Perpendicularly Magnetized Co/Ni Nanowire under In-Plane Magnetic Fields (2012)

We have investigated current-induced domain wall (DW) motion in a perpendicularly magnetized Co/Ni nanowire under in-plane (hard-axis) and perpendicular (easy-axis) external magnetic fields. The DW velocity was found to be almost independent of them in the range of ±50 Oe. The result shows that reliable device operation against an external magnetic field disturbance can be achieved using the present system.

Enhanced synchronization range from non-linear micromechanical oscillators (2015)

In this paper, we report that the synchronization range of micro-oscillators increases with increasing drive force when operating the oscillators in the non-linear regime. This enhancement is contrary to the same observation for oscillators operating in the linear regime where the synchronization range decreases with increasing drive force. This creates the ability to synchronize multiple oscillators operating in the non-linear regime across a greater frequency range to accommodate larger frequency deviations between devices caused by fabrication variances. We have observed the increased synchronization range in both mechanical hardening and electrostatic softening non-linear micro-oscillators.

Anisotropy enhanced dual magnetic layer design for high-density perpendicular recording (2005)

In this study, we employed anisotropy enhanced dual magnetic layer design, which improves signal-to-noise ratio (SNR) as well as adjacent track erasure (ATE) over the current single layer CoCrPtO media. The dual magnetic layer, consisting of a lower CoCrPtO layer and an upper CoCrPtB layer were deposited on SUL/Ta/Ru layer structure along with the single layer CoCrPtO and CoCrPtB media.
A Single Amino Acid Change in Rabies Virus Glycoprotein Increases Virus Spread and Enhances Virus Pathogenicity (2005)

Several rabies virus (RV) vaccine strains containing an aspartic acid (Asp) or glutamic acid (Glu) instead of an arginine (Arg) at position 333 of the RV glycoprotein (G) are apathogenic for immunocompetent mice even after intracranial inoculation. However, we previously showed that the nonpathogenic phenotype of the highly attenuated RV strain SPBNGA, which contains a Glu at position 333 of G, is unstable when this virus is passaged in newborn mice. While the Glu(333) remained unchanged after five mouse passages, an Asn(194)-->Lys(194) mutation occurred in RV G. This mutation was associated with increased pathogenicity for adult mice. Using site-directed mutagenesis to exchange Asn(194) with Lys(194) in the G protein of SPBNGA, resulting in SPBNGA-K, we show here that this mutation is solely responsible for the increase in pathogenicity and that the Asn(194)-->Lys(194) mutation does not arise when Asn(194) is exchanged with Ser(194) (SPBNGA-S). Our data presented indicate that the increased pathogenicity of SPBNGA-K is due to increased viral spread in vivo and in vitro, faster internalization of the pathogenic virus into cells, and a shift in the pH threshold for membrane fusion. These results are consistent with the notion that the RV G protein is a major contributor to RV pathogenesis and that the more pathogenic RVs escape the host responses by a faster spread than that of less pathogenic RVs.

CORROSION PROTECTION OF REINFORCEMENT IN MODIFIED HIGH-ALUMINA CEMENT CONCRETE (1996)

The aim was to evaluate contamination by bone-dust and formaldehyde when using a band-saw for preparations of the base of the skull and the cervical vertebral spine (stationary band-saw, 1400 upm, saw blade with 160 saw teeth/m; distances 19-26 cm, time intervals 55-90 s). The asservation of bone particles was done with adhesive microscopic slides and calcium-specific staining by alizarin-red. The quantification of air contamination was carried out with micrometry and a particle-counter. Dräger-tubes 0.2/9 were utilized for estimation of formaldehyde. The band-saw did not produce high amounts of bone-dust with suspension power. Nevertheless, 75% of the particles ranged below 5 microns in size and were respirable. Contamination decreased with an increasing height above the floor. A massive flow of particles was observed during the first minutes of sawing. The bone-dust spread some metres away. The formaldehyde levels ranged throughout between 0.5 and also over 5 ppm (MAK = 0.5 ppm). This fact makes clear an intensive contamination of the air. Therefore, a ventilation directed to the floor is necessary when a band-saw is used, as well as breathing masks and safety-goggles.
Global Energy Fairing of B-Spline Curves in Path Planning Problems (2007)

The paper is concerned with path planning for mobile robots. Specifically, the discussion is related to the following problem: Given an ordered sequence of points on the plane, construct a path that fits these points and satisfies certain smoothness requirements. These requirements may be different in different problems and imply basically that the constructed path is to be realizable. Such a problem arises, e.g., when it is required to follow in an automated mode a path stored as a discrete set of points, which, e.g., were collected by a GPS receiver installed on a car when it followed this path for the first time. Due to errors inherent in the data points, the shape of the curve approximating the desired path turns out often inappropriate. The shape of the curve can be improved by applying the so-called fairing, which consists in moving the original data points with the aim to minimize some fairness criterion. Adequate small variations of the data points preserve the proximity of the resulting path to the original data points and make it fairer. In the paper, a new global fairing method is proposed. It reduces the problem of constructing a fair cubic B-spline curve to solving a quadratic programming problem with simple constraints. The fairing criterion is based on minimizing jumps of the spline third derivative. The discussion is illustrated by numerical examples of fairing two actual paths constructed by data points collected by a GPS/GLONASS receiver mounted on a moving vehicle.
Combinatorial Mutasynthesis of Flavonoid Analogues from Acrylic Acids in Microorganisms (2007)

Flavonoids are plant secondary metabolites often used as nutraceutical supplements, but a growing number of unnatural flavonoids are being investigated as therapeutic agents. Cultures of Saccharomyces cerevisiae expressing recombinant flavonoid enzymes, including 4-coumaroyl:CoA ligase (4CL), chalcone synthase (CHS), chalcone isomerase (CHI), and flavanone 3beta-hydroxylase (FHT), produced novel flavanones and dihydroflavonols when fed with a number of aromatic acrylic acids. The flavonoid network also exhibited broad substrate specificity by converting muconic acid into a unique polypropanoid.

Robust wireless location over fading channels (2003)

This paper develops an estimation algorithm for the time and amplitude of arrival of a known transmitted sequence over a single-path fading channel. The algorithm is optimized to enhance robustness to fast channel fading and low signal-to-noise ratio (SNR) conditions, which are common in wireless location applications. The paper also presents a noise and fading bias correction technique for amplitude of arrival estimation that improves the estimation accuracy significantly. The proposed algorithm is then applied to the case of code-division multiple-access (CDMA) wireless location finding for which the paper gives simulation results that demonstrate significant estimation accuracy improvement over known algorithms.
Automatic moire contouring (1984)

A method of automatically reconstructing the 3-D surface of an object from a 2-D moire pattern has been extended to interpret ambiguous fringe patterns by displacing the object. Potential applications of the surface reconstruction technique include inspection, cad/cam, microscopy, and robot vision. The digitized binary image was segmented into labeled fringes, the contours were detected, and the surface was reconstructed. A coin was used as an example to illustrate the procedure. The feasibility of using automatic moire contouring to inspect surfaces is discussed.
Five New Discodermolide Analogues from the Marine Sponge<i>Discodermia</i>Species (2002)

Discodermolide (1) and five new discodermolide analogues trivially named 2-epi-discodermolide (2), 2-des-methyldiscodermolide (3), 5-hydroxymethyldiscodermolate (4), 19-des-aminocarbonyldiscodermolide (5), and 9(13)-cyclodiscodermolide (6) have been isolated from marine sponges belonging to the genus Discodermia collected from the Caribbean Sea. The isolation, structure elucidation, and biological activities of 2-6 are described. The natural analogues, which were isolated in trace amounts, exhibited significant variation of cytotoxicity against the cultured murine P-388 leukemia and A-549 human adenocarcinoma cells and suggested the importance of the C(7) through C(17) moiety for potency against cultured tumor cell lines.
Downlink multi-user interference alignment in compound MIMO-X channels (2011)

In this paper, we elaborated on a new interference alignment technique for downlink multi-user system in a MIMO-X channel with multiple antennas. We considered two transmitters, each equipped with M antennas, and L users, each equipped with K antennas. Here, we consider a MIMO-X scenario that some users are receiving transmissions from both transmitters. The proposed approach is focused on rank-1 transmission to each user while each transmitter only needs to know the CSI for its serving users and each user only needs to know its corresponding channels to the transmitters.
Metamaterial-Based Terahertz Imaging (2015)

This paper presents the design of an innovative, low-cost, uncooled, metamaterial-based terahertz (THz) focal plane array (FPA). A single pixel is composed of a resonant metamaterial absorber and micro-bolometer sensor integrated in a standard 180 nm CMOS process. The metamaterial is made directly in the metallic and insulating layers available in the six metal layer CMOS foundry process. THz absorption is determined by the geometry of the metamaterial absorber which can be customized for different frequencies. The initial prototype consists of a 5 ×5 pixel array with a pixel size of 30 μm ×30 μm and is readily scalable to more commercially viable array sizes. The FPA imaging capability is demonstrated in a transmission and reflection mode experiment by scanning a metallic object hidden in a manila envelope.
A CMOS low power current-mode polyphase filter (2009)

A new CMOS polyphase filter based on current followers is presented. Adoptions of such relatively simple building blocks and a filter structure employing minimum number of active elements, have lead to low power solution. The proposed filter is used to construct a 6th-order polyphase fully differential filter suitable for Bluetooth low-IF receiver. Experimental results show that the proposed design satisfies the selectivity and dynamic range specifications of Bluetooth while consuming relatively low power of 2.38mW.
Determination of Weight Percent Oxygen in Commercial Gasoline: A Comparison between FT-Raman, FT-IR, and Dispersive Near-IR Spectroscopies (1996)

The weight percent oxygen in commercial gasoline samples has been determined by using partial least-squares (PLS) regression analysis combined with either FT-Raman, FT-IR, or dispersive near-IR spectroscopy. Calibration models were constructed with the use of 33 MTBE oxygenated commercial gasolines. The minimum standard errors of validation with the use of leave-one-out validation are 0.156, 0.188, and 0.119 wt % oxygen for FT-Raman, FT-IR, and near-IR, respectively. An independent test set of 36 MTBE oxygenated commercial gasolines was used to further validate the PLS models. The minimum standard errors of prediction for the test set are 0.155, 0.143, and 0.131 wt % oxygen for FT-Raman, FT-IR, and near-IR, respectively. The wt % oxygen in all samples ranges from 0.2 to 3.262%.
Evaluation of a novel CT image reconstruction algorithm with enhanced temporal resolution (2011)

We present an evaluation of a novel algorithm that is designed to enhance temporal resolution in CT beyond the short-scan limit by making use of a histogram constraint. A minimum scan angle of 180° plus fan angle is needed to acquire complete data for reconstructing an image. Conventionally, this means that a temporal resolution of half the gantry rotation time is achievable in the isocenter and that an enhancement of temporal resolution can only be accomplished by a faster gantry rotation or by using a dual-source system. In this work we pursue a different approach, namely employing an iterative algorithm to reconstruct images from less than 180° of projections and using a histogram constraint to prevent the occurrence of limited-angle artifacts. The method is fundamentally different from previously published approaches using prior images and TV minimization. Furthermore, motion detection is used to enhance dose usage in those parts of the image where temporal resolution is not critical. We evaluate the technique with patient and phantom scans as well as using simulated data. The proposed method yields good results and image quality, both with simulated and with clinical data. Our evaluations show that an enhancement of temporal resolution to a value equivalent to about 120° of projections is viable, which corresponds to an enhancement of temporal resolution by about 30%. Furthermore, by employing motion detection, a substantial noise reduction can be achieved in those parts of the image where no motion occurs.
Scattering Properties of Individual Hedgehog Particles (2018)

“Hedgehog” particles (HPs) possess a micrometer-sized dielectric spherical core which is densely coated with nanoscale metal oxide spikes. This unique surface topography, resembling the appearance of a hedgehog, provides the particles with the exclusive physiochemical property to stably disperse in both polar and nonpolar solvents without the necessity of changing the surface chemistry. Optical extinction measurements of HP ensembles in aqueous solution indicate a broad spectral response in the visible range. However, there remains a dearth of fundamental knowledge about the cause of the broad optical resonance, as it can be a consequence of shape polydispersity in the many-particle system or intrinsic to each individual HP. In this paper, we present the first experimental study of the dark-field scattering of individual hydrophilic and hydrophobic HPs. Our measurements disclose that the expansive optical response in the visible spectral range is truly characteristic for the far-field scattering of a single HP. Our results also uncover how intrinsic particle features, such as spike length, as well as environmental changes affect the scattering of individual HPs. In particular, by changing the atmosphere around a hydrophilic HP from air to nitrogen and by completely immersing in water by employing a 3D optical trap, we discovered that the scattering from a hydrophilic HP is strongly modulated by excess water in its interstitial shell.
Transfer of the inflammatory disease of HLA-B27 transgenic rats by bone marrow engraftment. (1993)

We have previously produced lines of rats transgenic for HLA-B27 and human beta 2-microglobulin (h beta 2m) that develop a progressive inflammatory disease sharing many clinical and histologic features with the B27-associated human spondyloarthropathies, including gut and male genital inflammation, arthritis, and psoriasiform skin lesions. Other transgenic lines that express lower levels of B27 and h beta 2m remain healthy. To investigate the cellular basis for the multisystem inflammatory disease in these rats, we transferred lymphoid cell populations from disease-prone transgenic lines to irradiated disease-resistant transgenic and nontransgenic recipients. In recipients of cells from two different disease-prone lines, successful transfer required engraftment of bone marrow cells. Transfer of disease with fetal liver cells suggested that neither mature effector cells nor active disease in the donors was necessary for induction of disease in the recipients. Remission of the spontaneous disease in irradiated transgenic rats was induced by engraftment of nontransgenic bone marrow. These results suggest that the expression of HLA-B27 in bone marrow-derived cells alone is sufficient for the development of B27-associated disease, and that disease transfer requires engraftment of a bone marrow precursor cell for which mature cells in spleen or in lymph node cannot substitute.
