Analysis of phase regeneration of DPSK/DQPSK signals based on phase-sensitive amplification (2009)

Amplification and phase regeneration can be realized using a phase-sensitive amplifier (PSA). The phase regeneration of differential phase-shift keying (DPSK) signals based on PSA is analyzed theoretically. We realize the phase regeneration of differential quadrature phase-shift keying (DQPSK) signals based on a structure using two balanced PSAs. Simulations show that nearly ideal phase regeneration can be achieved for the DPSK/DQPSK signals.
Improved delay-line based digital PWM for DC-DC converters (2011)

An improved delay-line based digital pulse-width modulator (DPWM) architecture for DC-DC converters is presented to significantly enhance the area and power efficiency. In order to reuse the delay elements, the proposed scheme utilises the rising delay and falling delay to achieve the coarse and fine resolution of the DPWM, respectively. An 8-bit DPWM employing the improved architecture was implemented in SMIC standard 0.13 µm CMOS process. Simulation results indicate that a 90% of size saving is achieved for 8-bit resolution compared to the conventional method. Owing to the decrease in the number of delay elements, power consumption is also reduced.
Extraction and optimization of B-spline PBD templates for recognition of connected handwritten digit strings (2002)

The recognition of connected handwritten digit strings is a challenging task due mainly to two problems: poor character segmentation and unreliable isolated character recognition. The authors first present a rational B-spline representation of digit templates based on Pixel-to-Boundary Distance (PBD) maps. We then present a neural network approach to extract B-spline PBD templates and an evolutionary algorithm to optimize these templates. In total, 1000 templates (100 templates for each of 10 classes) were extracted from and optimized on 10426 training samples from the NIST Special Database 3. By using these templates, a nearest neighbor classifier can successfully reject 90.7 percent of nondigit patterns while achieving a 96.4 percent correct classification of isolated test digits. When our classifier is applied to the recognition of 4958 connected handwritten digit strings (4555 2-digit, 355 3-digit, and 48 4-digit strings) from the NIST Special Database 3 with a dynamic programming approach, it has a correct classification rate of 82.4 percent with a rejection rate of as low as 0.85 percent. Our classifier compares favorably in terms of correct classification rate and robustness with other classifiers that are tested.

Detecting dominance QTL in poultry pedigrees using variance component methodology (2007)

Methods that detect QTL within commercial populations circumvent the need for expensive experimental populations and facilitate direct application of results through marker assisted selection. Variance component analysis (VCA) uses phenotypic, pedigree and marker information within a mixed linear model to simultaneously detect QTL and estimate breeding values. The inclusion of non-additive effects has potential for greater accuracy of selection and understanding of underlying mechanisms. The linear model can be extended to include higher order effects such as dominance, however, there is little information on empirical power. Here VCA was applied to real and simulated commercial broiler data to detect additive and dominant QTL effects.
Phylogenetic and Evolutionary Patterns in Microbial Carotenoid Biosynthesis Are Revealed by Comparative Genomics (2010)

Comparative genomics analyses of microbial carotenoid biosynthetic proteins indicate a much greater taxonomic diversity then that identified based on structural and biosynthetic data, and divides microbial carotenoid biosynthesis into several, well-supported phylogenetic lineages not evident previously. This phylogenetic framework is applicable to understanding the evolution of specific carotenoid biosynthetic proteins or the unique characteristics of carotenoid biosynthetic evolution in a specific phylogenetic lineage. Together, these analyses suggest a "bramble" model for microbial carotenoid biosynthesis whereby later biosynthetic steps exhibit greater evolutionary plasticity and reticulation compared to those closer to the biosynthetic "root". Structural diversification may be constrained ("trimmed") where selection is strong, but less so where selection is weaker. These analyses also highlight likely productive avenues for future research and bioprospecting by identifying both gaps in current knowledge and taxa which may particularly facilitate carotenoid diversification.
Hot-Dip Galvanizing of Q345 Steel with Pre-Plating Nickel (2003)

High strength low alloy structure steel (Q345) specimens containing 0.38 wt% Si were electroplated with 2.5～10.0 μm nickel layer firstly and then galvanized in molten Zn at 733 K for various time. Formation and growth of alloy layer on the surface of specimens was examined. The results showed that electroplating prior to galvanizing was an effective way to reduce excessive coating thickness and gray surface appearance. The thicker the electroplating Ni was, the slower the alloy layers grew. Ni\|Zn alloy layer γ' andγwas first formed on the surface of electroplating Ni deposit. After the Ni layer was consumed, Fe\|Zn alloy layer δ and Ni\|Zn alloy layers δ\-2 appeared. Then δ\-2 disappeared and the final microstructure was composed of continuous δ layer and massive ζ dispersed in the η layer. Inhibition of rapid growth of hot\|dip galvanizing coating on the high silicon steel resulted mainly from the continuous and compact Ni \|Zn alloy layer.
Visual distortion gauge based on discrimination of noticeable contrast changes (2005)

This paper presents a method to discriminate pixel differences according to their impact toward perceived visual quality. Noticeable local contrast changes are formulated firstly since contrast is the basic sensory feature in the human visual system (HVS) perception. The analysis aims at quantifying the actual impact of such changes (further divided into increases and decreases on edges) in different signal contexts. An associated full-reference distortion metric proposed next provides better match with the HVS viewing. Experiments have used two independent visual data sets and the related subjective viewing results, and demonstrated the performance improvement of the proposed metric over the relevant existing ones with various video/images and under diversified test conditions. The proposed metric is particularly effective to visual signal with blurring and luminance fluctuations as the major artifacts, and brings about the fundamental improvement when sharpened image edges are involved.
Defining Pseudorange Integrity - Overbounding (2000)

One of the most critical requirements for aviation 
applications is integrity. For Category I precision 
approach, the International Civil Aviation Organization 
(ICAO) has defined an integrity requirement of 10-7 per 
approach on the probability that the system fails in a way 
that causes misleading information. Since the 
performance of GNSS can vary dramatically depending on 
satellite geometry, mathematical bounds on the position 
error have been defined to evaluate this requirement for a 
particular approach. These bounds are the horizontal and 
vertical protection levels (HPL and VPL, respectively), 
and are defined in RTCA and ICAO documents. 

The protection level equations are constructed on the 
assumption that the individual error components 
(pseudorange errors) are exactly characterized by a zero-
mean Normal distribution, whose variance is known. 
Unfortunately, this assumption has not been validated. In 
fact, testing has indicated that there can be small residual 
means and the tails of the error distribution are not 
necessarily characterized by a Normal distribution. In 
order to generalize the integrity requirements for 
individual pseudorange error components, these effects 
must be accommodated. 
This paper proves that the assumption for a zero-mean, 
Normal error distribution can be replaced by a 
requirement that the error distribution is symmetric, 
unimodal, and whose cumulative distribution function 
(cdf) is bounded by a Normal error distribution 
(overbounded for errors less than the mean, underbounded 
for errors greater than the mean). This result is extended 
to accommodate non-zero means, which can be accounted 
for by inflating the variance of the assumed Normal error 
model. Three methods of inflating this variance are 
described.
Incorporating signature-monitoring technique in VLIW processors (2004)

This paper presents the architecture of watchdog processor using hybrid signature-monitoring technique to detect the control-flow errors occurring in the VLIW processor. The hybrid signature-monitoring technique combines the vertical signature scheme with the horizontal signature scheme. The detailed designs of the watchdog processor that include the synchronous issue between watchdog processor and VLIW processor are discussed. We then implement and validate the proposed watchdog processor in VHDL. The fault simulation is conducted to justify the error-defection coverage and latency.

Development of a Niobium target for routine production of [18F]fluoride with a MC 16 Scanditronix cyclotron (2006)

The purpose with this work has been to develop and construct a Niobium target for the production of [18F]fluoride with a MC 16 Scanditronix cyclotron. The future demand larger amounts of [18F]fluoride and to satisfy the forthcoming needs an enhanced target needs to be installed on the cyclotron. The old target could have provided the forthcoming needs but to obtain good margins it is important with a better target that benefits the full potential of a MC 16 Scanditronix cyclotron. The old target could only stand approximately half the proton beam capacity of the cyclotron.The work was carried out at the department of Medical Radiation Physics, Jubileum Institute and at the University hospital of Lund. Possible enhancements with the old target were identified and incorporated into the new target. Target parts were constructed in the hospital’s own workshop meanwhile more advanced gadgets had to be ordered from specialized firms. The material of the target chamber was carefully chosen (Niobium) according to chemical inertness, mechanical strength and activation (radioactive isotopes generated when irradiated). Mathematical calculations were applied onto real situations to estimate pressure tolerances and heat transportations. Different foil materials were investigated. Irradiation experiments, of protons into the enriched H218O-water, were performed with a MC 16 Scanditronix cyclotron.The results are very good. For one hour irradiation at 40 μA, 93 GBq F- was produced (extrapolated values) meanwhile for a two hour irradiation at 40 μA, 142 GBq F- was produced (95 % 18O-water). The following synthesis resulted in 87 GBq which correspond to a yield of 62 %. The yield for the FDG synthesis is normal and the productions are large. No discoloration of water occurred. The chemical inertness of the Niobium material has been verified.The new target has increased the production capacity of approximately 300 %, from 32 GBq for the old target, to 93 GBq for the new target (1 hour irradiation). The saturation value per micro amperes is approximately 7.30 GBq/μA. The biggest improvement originates from the new target’s capacity to benefit the full proton beam intensity capacity of the MC 16 Scanditroni
Biological Relevance of Adduct Detection to the Chemoprevention of Cancer (2004)

Adducts arise from the chemical modification of bases in DNA or amino acids in proteins by toxic chemicals. Many chemicals known to be carcinogenic in humans have been shown to form adducts or to cause oxidative damage to genomic DNA in model systems. Biomarkers of carcinogenesis reflect biological events that take place between exposure to external or endogenous carcinogens and the subsequent development of cancer. Therapeutic intervention for the purpose of cancer chemoprevention may modify these biomarkers. In this article, the potential efficacy of DNA adducts as biomarkers of carcinogenesis and chemoprevention is discussed using criteria defined for phases of biomarker development. The sensitivity of adduct detection in histologically normal tissue offers opportunities for the early detection of carcinogenesis. Extensive evidence for aflatoxin B(1) adducts as biomarkers of risk and progression of hepatic carcinogenesis and for oxidative DNA adducts as biomarkers of the development of prostate carcinogenesis is reviewed together with the clinical trials measuring these adducts as biomarkers of the efficacy of chemoprevention. Favorable modification of oxidative DNA adducts by dietary intervention and chemoprevention has been demonstrated in preclinical and clinical studies. Protein adducts and DNA adducts in blood constituents or urine may act as useful surrogates for the target organ. Additional information regarding reliability, reproducibility, specificity, and confounding variables are required at the clinical level to validate adducts as suitable biomarkers of chemoprevention. "We do not administer antihypertensive drugs to patients in clinical trials without checking their blood pressure, so why should we give antioxidants without checking that they have decreased oxidant status.

Studies on the phase separation of polyetherimide‐modified epoxy resin, 1. Effect of curing rate on the phase structure (1997)

Abstract The effect of the curing rate on the phase structure of a new polyetherimide‐modified epoxy systems was studied. Through changing cure agents and cure temperature, selecting different molecular weights and end groups of the polyetherimide (PEI) polymers, the curing rates, the phase separation processes and the morphology of the cured blends were observed employing differential scanning calorimetry, time‐resolved light scattering and scanning electron microscopy. The highly active cure agent 4,4′‐oxydianiline leads to phase separation in the early stage of spinodal decomposition and to a co‐continuous phase structure. As to the 4,4′‐diaminodiphenyl sulfone cured systems, not only the curing rate, but the mobility of the PEI molecule also affected the final morphology of the PEI‐modified epoxy resin.
Production and Application of Polyclonal and Monoclonal Antibodies (1993)

During the last 20 years, the use of antibodies has become a self-evident method for biochemists, as well as cell and molecular biologists. The reason for this is that antibodies have proven to be excellent probes for the recognition of proteins, peptides, lipids, and hormones. Particularly, the high specificity of an antibody simplifies studies concerning, for instance: 1. The synthesis, processing, and transport of proteins; 2. The discrimination of different isoforms of an enzyme; 3. The localization of proteins. Alternatively, antibodies can be used in a wide variety of quantitative studies dealing with concentrations of different types of molecules in body fluids, tissue samples, or food.
[Adhesion molecules and trophoblastic invasion]. (1995)

At the time of implantation, the extracellular matrix proteins laminin and fibronectin are abundant in the decidua and are distributed pericellularly around each individual stromal cells. First trimester human trophoblast express both laminin and fibronectin receptors, specifically the alpha 1 beta 1, alpha 5 beta 1, alpha 6 beta 1 and alpha 6 beta 4 integrin heterodimers. We have demonstrated that in vitro adhesion of first trimester human trophoblast to purified extracellular matrix proteins and to purified decidual stromal cell monolayers can be inhibited by monoclonal antibodies directed against appropriate integrin subunits and by synthetic peptides containing an RGD sequence. We have also examined the downstream events of trophoblast matrix adhesion, such as integrin mediated signal transduction and the production of metalloproteinases. The implications of these interactions are discussed.

The Data-View Model of IEC 61850 Server (2006)

IEC 61850 presents a set of models for substation automation system which is independent from any implementation. Besides models and services, a clear framework is the focus of the research when a manufacturer designs a product according to the IEC 61850. This paper presents a layered framework which consists of data, view and control. Server software is made up of the data, view, control and communication. Focused on the modularization and code reusing, view, data, control and communication were separately presented and a method of applying this framework to intelligent electronic device was discussed.
Rate Control Optimization for Temporal-Layer Scalable Video Coding (2011)

A novel frame-level rate control (RC) algorithm is presented in this paper for temporal scalability of scalable video coding. First, by introducing a linear quality dependency model, the quality dependency between a coding frame and its references is investigated for the hierarchical B-picture prediction structure. Second, linear rate-quantization (R-Q) and distortion-quantization (D-Q) models are introduced based on different characteristics of temporal layers. Third, according to the proposed quality dependency model and R-Q and D-Q models for each temporal layer, adaptive weighting factors are derived to allocate bits efficiently among temporal layers. Experimental results on not only traditional quarter common intermediate format/common intermediate format but also standard definition and high definition sequences demonstrate that the proposed algorithm achieves excellent coding efficiency as compared to other benchmark RC schemes.
Interesting nuggets and their impact on definitional question answering (2007)

Current approaches to identifying definitional sentences in the context of Question Answering mainly involve the use of linguistic or syntactic patterns to identify informative nuggets. This is insufficient as they do not address the novelty factor that a definitional nugget must also possess. This paper proposes to address the deficiency by building a "Human Interest Model" from external knowledge. It is hoped that such a model will allow the computation of human interest in the sentence with respect to the topic. We compare and contrast our model with current definitional question answering models to show that interestingness plays an important factor in definitional question answering.

Comparing data-mining algorithms developed for longitudinal observational databases (2012)

Longitudinal observational databases have become a recent interest in the post marketing drug surveillance community due to their ability of presenting a new perspective for detecting negative side effects. Algorithms mining longitudinal observation databases are not restricted by many of the limitations associated with the more conventional methods that have been developed for spontaneous reporting system databases. In this paper we investigate the robustness of four recently developed algorithms that mine longitudinal observational databases by applying them to The Health Improvement Network (THIN) for six drugs with well document known negative side effects. Our results show that none of the existing algorithms was able to consistently identify known adverse drug reactions above events related to the cause of the drug and no algorithm was superior.

Real-Time Driver Drowsiness Detection for Embedded System Using Model Compression of Deep Neural Networks (2017)

Driver's status is crucial because one of the main reasons for motor vehicular accidents is related to driver's inattention or drowsiness. Drowsiness detector on a car can reduce numerous accidents. Accidents occur because of a single moment of negligence, thus driver monitoring system which works in real-time is necessary. This detector should be deployable to an embedded device and perform at high accuracy. In this paper, a novel approach towards real-time drowsiness detection based on deep learning which can be implemented on a low cost embedded board and performs with a high accuracy is proposed. Main contribution of our paper is compression of heavy baseline model to a light weight model deployable to an embedded board. Moreover, minimized network structure was designed based on facial landmark input to recognize whether driver is drowsy or not. The proposed model achieved an accuracy of 89.5% on 3-class classification and speed of 14.9 frames per second (FPS) on Jetson TK1.
