Fast Computation of Kernel Estimators (2010)

The computational complexity of evaluating the kernel density estimate (or its derivatives) at m evaluation points given n sample points scales quadratically as O(nm)—making it prohibitively expensive for large datasets. While approximate methods like binning could speed up the computation, they lack a precise control over the accuracy of the approximation. There is no straightforward way of choosing the binning parameters a priori in order to achieve a desired approximation error. We propose a novel computationally efficient ε-exact approximation algorithm for the univariate Gaussian kernel-based density derivative estimation that reduces the computational complexity from O(nm) to linear O(n+m). The user can specify a desired accuracy ε. The algorithm guarantees that the actual error between the approximation and the original kernel estimate will always be less than ε. We also apply our proposed fast algorithm to speed up automatic bandwidth selection procedures. We compare our method to the best available binning methods in terms of the speed and the accuracy. Our experimental results show that the proposed method is almost twice as fast as the best binning methods and is around five orders of magnitude more accurate. The software for the proposed method is available online.

Time course of plasma histamine and tryptase following food challenges in children with suspected food allergy. (1993)

This study was undertaken to investigate the kinetics of histamine and tryptase in the circulation of patients with food allergy and to determine whether the measurements of plasma histamine and tryptase concentrations after food challenges provided additional predictive markers for the diagnosis and evaluation of food allergy. Twenty-one open food challenges were performed on 13 patients with suspected food allergy. Plasma histamine and tryptase concentrations were measured during 4 hours after challenge. In the group of patients with immediate reactions after challenges, the mean plasma histamine concentration rose significantly at 120 and 240 minutes after the challenge, and the mean plasma tryptase concentration was increased significantly at 240 minutes after challenge. Plasma histamine and tryptase concentrations were measured during 24 hours after 8 open food challenges in 7 other patients with suspected food allergy. In each patient with a nonimmediate reaction, plasma histamine concentrations were increased at the onset of symptoms after challenge, but no plasma tryptase concentrations increased. The elevation of plasma histamine and tryptase in patients with immediate reactions following food challenge indicates mast cell activation. On the other hand, the elevation of plasma histamine without elevated plasma tryptase in the patients with nonimmediate reactions following food challenge may indicate basophil activation rather than mast cell activation. Plasma histamine and tryptase measurements after food challenge may be useful in the detection and evaluation of food allergy.
Factors Influencing the Collagenase Digestion Phase of Human Islet Isolation (2007)

Substantial advances in human islet isolation technology have occurred during the past decade. However, it is still difficult to recover the entire quantity of islets contained in a pancreas. A major obstacle to successful human islet isolation has been the variability of the collagenase digestion phase of islet isolation. Future advances in enzyme technology will make it possible to optimally liberate islets with enzyme blends "tailor-made" for each individual donor pancreas. Such innovative strategies will be advantageous in improving islet isolation efficiency, recovery, viability, and ultimately posttransplant function.
Thermal study on the copolymers of phthalonitrile and phenylnitrile‐functional benzoxazines (1999)

Ortho-, meta-, and para-phenylnitrile–functional benzoxazines are polymerized at different compositions with phthalonitrile-functional monomers providing copolybenzoxazines of high thermal stability and easy processability. The most positive effect on these properties is obtained on copolymerizing phthalonitrile- and ortho-phenylnitrile–functional benzoxazines. Thermal decomposition of these polybenzoxazines is studied by thermogravimetry (TGA). It is demonstrated that only 30 mol % of phthalonitrile-functional benzoxazine added to the ortho-phenylnitrile–substituted monomer improves char yield significantly from 59 to 77 wt %, which is the value of neat phthalonitrile-based polybenzoxazine. Glass transition temperature (Tg) also dramatically increases from 180°C for neat ortho-phenylnitrile polymer to 294°C for the copolymer with 30 mol % of phthalonitrile-functional monomer. Additionally, the high melt viscosity of phthalonitrile-functional benzoxazines is dramatically decreased upon blending with phenylnitrile-functional monomer. © 1999 John Wiley & Sons, Inc.

Dynamic Cloud Resource Reservation via Cloud Brokerage (2013)

Infrastructure-as-a-Service clouds offer diverse pricing options, including on-demand and reserved instances with various discounts to attract different cloud users. A practical problem facing cloud users is how to minimize their costs by choosing among different pricing options based on their own demands. In this paper, we propose a new cloud brokerage service that reserves a large pool of instances from cloud providers and serves users with price discounts. The broker optimally exploits both pricing benefits of long-term instance reservations and multiplexing gains. We propose dynamic strategies for the broker to make instance reservations with the objective of minimizing its service cost. These strategies leverage dynamic programming and approximate algorithms to rapidly handle large volumes of demand. Our extensive simulations driven by large-scale Google cluster-usage traces have shown that significant price discounts can be realized via the broker.
Passive harmonic mode-locking in all-fibre soliton laser: energy states and stability aspects (1994)

The behavior of a passively mode-locked soliton laser, under different energy states, is studied by using a numerical simulation. The shorter pulse obtainable is determined, pointing out the soliton properties of the output pulses. In the case of harmonic mode-locking, power quantisation related to the number of existing pulses in the cavity, is obtained and repetition rate instability is detected. It is found that by introducing a narrow band optical filter in the cavity and by optimising the filter bandwidth, this instability is substantially reduced.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Analysis of wide color gamut of green/red bilayered freestanding phosphor film-capped white LEDs for LCD backlight (2015)

In this study, we propose green/red bilayered freestanding phosphor film-capped white light-emitting diodes (W-LEDs) using InGaN blue LEDs and narrowband red and green phosphors to realize a wide color gamut in a liquid crystal display (LCD) backlight system. The narrowband K2SiF6:Mn4+ (KSF) red and SrGa2S4:Eu2+ (SGS) green phosphors are synthesized using a facile etching synthetic process and flux-aided solid state reaction under a H2S atmosphere, respectively, and the freestanding phosphor films are fabricated using a delamination method with water-soluble polymer, polystyrene sulfonic acid, PEDOT/PSS, and interlayered phosphor film. Various phosphor concentrations of green/red bilayered freestanding phosphor film-capped W-LEDs exhibit a correlated color temperature (CCT) and luminous efficacy range of 11,390 K ~6,540 K and 99 lm/W ~124 lm/W, respectively, with an applied current of 60 mA. The W-LED with green (12.5 wt%)/red (40 wt%) bilayered phosphor film, which exhibited luminous efficacy of 105 lm/W at the CCT of 8,330 K, is selected and the color gamut of the bare LED and phosphor RG and the filtered RGB triangle is calculated to be more than ~95% and ~86.4%, respectively, relative to the NTSC in the 1931 CIE color coordinates space.
Estimation of the elastic stiffness coefficient <i>c</i>13 of fixed tendon and fixed myocardium (1995)

Recent studies from our laboratory have detailed the anisotropy of velocity of quasilongitudinal-mode ultrasonic waves through formalin fixed samples of normal human myocardium and bovine Achilles tendon. Results of these studies were used to determine the elastic stiffness coefficients c33, corresponding to the propagation of longitudinal-mode waves parallel to the fiber axis of the tissue, and c11, corresponding to the propagation of longitudinal-mode waves perpendicular to the fiber axis. For a tissue possessing a unidirectional arrangement of fibers with a random transverse distribution, three additional coefficients, c13, c44, and c12, are needed to describe its linear mechanical properties completely. Direct ultrasonic measurements of these coefficients in solids typically require the propagation of transverse-mode waves through the sample. Such measurements are difficult to perform in soft tissues because transverse-mode ultrasonic waves are very highly attenuated by the tissue. This study therefore employs a technique to estimate c13 based on measurements of the velocity of quasilongitudinal-mode ultrasonic waves for numerous angles of propagation relative to the fiber axis of the tissue. Analysis of data obtained from formalin fixed bovine Achilles tendon and human myocardium yield estimated values for c13 of 3.17 and 2.46 GPa, respectively.

Pervasive computing technologies for retail in-store shopping (2005)

Retailers are constantly in search for ways to enhance customer satisfaction so as to differentiate with the competition and increase revenue. This paper describes an in-store commerce server implementation that leverages pervasive computing technologies to redefine the in-store shopping experience. The server evolves the existing point-of-sale systems into a store integration platform complete with reusable in-store solution building blocks. The paper illustrates how customer touch points such as cart-mounted Web pads can be supported to enable location-sensitive, personalized shopping assistance, and incremental self-checkout. New collaborative shopping paradigms can be created by service-oriented process choreography with other sales channels.
A novell wireless forklift positioning system for indoor and outdoor use (2008)

Precise tracking of industrial transportation means - e.g. automatic guided vehicles, cranes, forklifts, etc. - is becoming increasingly important for optimizing logistics processes and storage management. Real time forklift tracking can supplement or replace RFID systems in applications where flexible storage is wanted, where real time information is needed or when item tagging is inappropriate due to costs or physical constrains. In this paper a high performance 5.8 GHz wireless forklift positioning system is introduced. Round-trip time-of-flight (RTOF) measurements provide a set of 1D distance values between an arbitrary number of mobile and fixed secondary radar units attached to the forklift and to the infrastructure, respectively. With an optimized geometry based heuristic localization method the position and orientation of the forklift is derived. The proposed method can deal with faulty RTOF measurements, e.g. due to multipath distortions, and it enables a robust and reliable localization. The proposed RTOF system concept allows a minimal complexity of the infrastructure since no backbone network and no dedicated synchronization scheme is needed. An indoor test campaign with a forklift in a steel mill proved a measurement uncertainty of position and orientation below ±5 cm and ±10°, respectively, even without the use of any assisting inertial or dead reckoning sensors. This outstanding performance makes the system ideally suited for various applications in production, logistics and storage.

Enhanced Stat3 Activation in POMC Neurons Provokes Negative Feedback Inhibition of Leptin and InsulinSignaling in Obesity (2009)

Leptin-stimulated Stat3 activation in proopiomelanocortin (POMC)-expressing neurons of the hypothalamus plays an important role in maintenance of energy homeostasis. While Stat3 activation in POMC neurons is required for POMC expression, the role of elevated basal Stat3 activation as present in the development of obesity has not been directly addressed. Here, we have generated and characterized mice expressing a constitutively active version of Stat3 (Stat3-C) in POMC neurons (Stat3-C(POMC) mice). On normal chow diet, these animals develop obesity as a result of hyperphagia and decreased POMC expression accompanied by central leptin and insulin resistance. This unexpected finding coincides with POMC-cell-specific, Stat3-mediated upregulation of SOCS3 expression inhibiting both leptin and insulin signaling as insulin-stimulated PIP(3) (phosphatidylinositol-3,4,5 triphosphate) formation and protein kinase B (AKT) activation in POMC neurons as well as with the fact that insulin's ability to hyperpolarize POMC neurons is largely reduced in POMC cells of Stat3-C(POMC) mice. These data indicate that constitutive Stat3 activation is not sufficient to promote POMC expression but requires simultaneous PI3K (phosphoinositide 3-kinase)-dependent release of FOXO1 repression. In contrast, upon exposure to a high-fat diet, food intake and body weight were unaltered in Stat3-C(POMC) mice compared with control mice. Taken together, these experiments directly demonstrate that enhanced basal Stat3 activation in POMC neurons as present in control mice upon high-fat feeding contributes to the development of hypothalamic leptin and insulin resistance.

Detection, pathogenesis, and therapy of respiratory syncytial virus infections (1988)

Respiratory syncytial virus (RSV) infection is a major cause of serious lower respiratory disease in infancy and early childhood. The unique pathogenesis of lower respiratory illness due to RSV offers some intriguing clues to the role of the human immune system in both protection against and development of respiratory illness. More than any other virus, rapid diagnostic techniques have been especially successful in identifying RSV infection. Many of these techniques could be easily adaptable to diagnosis of influenza virus infection and other agents. Finally, ribavirin therapy of RSV infection represents one of the few instances in which antiviral therapy has been shown to be effective for respiratory illnesses. Fundamental observations in these areas in the case of RSV infection open up new and exciting pathways for investigation of respiratory infection due to other viral, chlamydial, and mycoplasmal agents.
Statistical properties of measured X-ray intensities affected by counting loss (2008)

The statistical properties of X-ray intensities measured with counting systems have been experimentally investigated. A formula of statistical variance for the intermediately extended dead-time model is proposed and compared with the experimentally evaluated variance obtained from repeated measurements based on Chipman's foil method applied to X-ray detection systems of laboratory and synchrotron powder diffractometers. It has been found that the variance of the observed intensities is smaller than the average of count, as has been suggested by conventional theoretical models for counting loss. It is shown that the statistical errors can be predicted by applying an intermediately extended dead-time model including dead-time τ and degree of extension ρ as fixed parameters.
