TOF Depth Map Super-resolution Using Compressive Sensing (2013)

Although Time-of-Flight (TOF) camera can provide real-time depth information from a real scene, the resolution of depth map captured by TOF camera is rather limited compared to HD color cameras, and thus it cannot be directly used in 3D reconstruction. In order to handle this problem, this paper proposes a novel compressive sensing (CS) based depth map super-resolution method, which transforms a low resolution depth map to a high resolution depth map. Different from previous depth map SR methods, this algorithm uses a model-based CS as reconstruction theory, and this method also builds a TOF camera sampling model which is used in depth map SR. Experimental results show that the proposed method outperforms state-of-the-art methods for depth map super-resolution.
A zero-current-switching PWM flyback converter with a simple auxiliary switch (1999)

A simple and effective approach of turning an isolated hard-switched converter design into a soft-switched one is presented. By adding an auxiliary winding, switch and small capacitor to the conventional pulsewidth modulation (PWM) isolated flyback converter, all switches and diodes are softly turned on and off. No extra active or passive voltage clamp circuit is needed to suppress voltage stress on the switching devices that were usually found in classical converters. A zero-current-switching (ZCS) PWM flyback converter topology with multiple outputs is analyzed and examined. The proposal inherently utilizes the leakage inductance of the "flyback" transformer to achieve ZCS of all switching devices. A complete steady-state DC analysis and the operating principle are described. The performance of an 80 W experimental converter prototype with dual-voltage outputs is included.
Dependency Analysis and Improved Parameter Estimation for Dynamic Composite Load Modeling (2016)

Dynamic load modeling by fitting the input-output measurements during fault events is crucial for power system dynamic studies. The WECC composite load model (CMPLDW) has been developed recently to better represent fault-induced delayed-voltage-recovery (FIDVR) events, which are of increasing concern to electric utilities. However, the model nonlinearity and large number of parameters of the CMPLDW model pose severe identifiability issues and performance degradation for the measurement-based load modeling approach using the classical nonlinear least-squares (NLS) objective. This paper will first present a general framework that can effectively analyze and visualize the parameter dependence of complex dynamic load models with large numbers of parameters under FIDVR. Furthermore, we propose to improve the parameter estimation performance by regularizing the NLS error objective using a priori information about parameter values. Effectiveness of the proposed dependence analysis and parameter estimation scheme is validated using both synthetic and real measurement data during faults. Albeit focused on CMPLDW, the proposed approaches can be readily used for composite load modeling in general.

Fitting Tweedie's compound poisson model to insurance claims data (1994)

Abstract We discuss the estimation and inference problems for the Tweedie compound Poisson process and its application to tarification. For data in the form of the total claim and number of claims for a given time interval and a given exposure, the Tweedie process corresponds to a Poisson process of claims and gamma distributed claim sizes. The model has three parameters, namely the mean claim rate, a dispersion parameter and a shape parameter, and the exposure enters as a weight via the dispersion parameter. The Tweedie process is an exponential dispersion model for fixed value of the shape parameter, and hence regression models for the claim rate may be fitted as in generalized linear models. The shape parameter is estimated by maximum likelihood, and inference is based on the likelihood ratio test, rather than the usual analysis of deviance. A GLIM 4 program for estimation in the model is presented.
Imatinib Reverses Doxorubicin Resistance by Affecting Activation of STAT3-Dependent NF-κB and HSP27/p38/AKT Pathways and by Inhibiting ABCB1 (2013)

Despite advances in cancer detection and prevention, a diagnosis of metastatic disease remains a death sentence due to the fact that many cancers are either resistant to chemotherapy (conventional or targeted) or develop resistance during treatment, and residual chemoresistant cells are highly metastatic. Metastatic cancer cells resist the effects of chemotherapeutic agents by upregulating drug transporters, which efflux the drugs, and by activating proliferation and survival signaling pathways. Previously, we found that c-Abl and Arg non-receptor tyrosine kinases are activated in breast cancer, melanoma, and glioblastoma cells, and promote cancer progression. In this report, we demonstrate that the c-Abl/Arg inhibitor, imatinib (imatinib mesylate, STI571, Gleevec), reverses intrinsic and acquired resistance to the anthracycline, doxorubicin, by inducing G2/M arrest and promoting apoptosis in cancer cells expressing highly active c-Abl and Arg. Significantly, imatinib prevents intrinsic resistance by promoting doxorubicin-mediated NF-κB/p65 nuclear localization and repression of NF-κB targets in a STAT3-dependent manner, and by preventing activation of a novel STAT3/HSP27/p38/Akt survival pathway. In contrast, imatinib prevents acquired resistance by inhibiting upregulation of the ABC drug transporter, ABCB1, directly inhibiting ABCB1 function, and abrogating survival signaling. Thus, imatinib inhibits multiple novel chemoresistance pathways, which indicates that it may be effective in reversing intrinsic and acquired resistance in cancers containing highly active c-Abl and Arg, a critical step in effectively treating metastatic disease. Furthermore, since imatinib converts a master survival regulator, NF-κB, from a pro-survival into a pro-apoptotic factor, our data suggest that NF-κB inhibitors may be ineffective in sensitizing tumors containing activated c-Abl/Arg to anthracyclines, and instead might antagonize anthracycline-induced apoptosis.
Querying the trajectories of on-line mobile objects (2001)

Position data is expected to play a central role in a wide range of mobile computing applications, including advertising, leisure, safety, security, tourist, and traffic applications. Applications such as these are characterized by large quantities of wirelessly Internet-worked, position-aware mobile objects that receive services where the objects' position is essential. The movement of an object is captured via sampling, resulting in a trajectory consisting of a sequence of connected line segments for each moving object. This paper presents a technique for querying these trajectories. The technique uses indices for the processing of spatiotemporal range queries on trajectories. If object movement is constrained by the presence of infrastructure, e.g., lakes, park areas, etc., the technique is capable of exploiting this to reduce the range query, the purpose being to obtain better query performance. Specifically, an algorithm is proposed that segments the original range query based on the infrastructure contained in its range. The applicability and limitations of the proposal are assessed via empirical performance studies with varying datasets and parameter settings.
Sitagliptin and metformin combination therapy for the treatment of Type 2 diabetes (2011)

Insulin secretion and insulin sensitivity are impaired in Type 2 diabetes. Metformin improves insulin sensitivity by inhibiting hepatic glucose release. It is the preferred drug for first-line treatment in Type 2 diabetes. Sitagliptin, the first marketed dipeptidyl peptidase-IV inhibitor, improves insulin and glucagon secretions of the pancreatic β- and α-cells, respectively, in a strictly glucose-dependent manner by raising endogenous active glucagon-like peptide-1 concentrations. The combination of metformin and sitagliptin thus offers a beneficial and complementary addition of important drug actions on insulin resistance and insulin secretion. Metformin and sitagliptin are also available as a fixed-dose combination. This article reviews the published clinical studies on both substances and their combination, and evaluates the potential benefit of the metformin plus sitagliptin combination.
Nanopatterned Surface Effect on the Epitaxial growth of InGaN/GaN Multi-quantum Well Light Emitting Diode Structure (2009)

The authors fabricated a nanopatterned surface on a GaN thin film deposited on a sapphire substrate and used that as an epitaxial wafer on which to grow an InGaN/GaN multi-quantum well structure with metal-organic chemical vapor deposition. The deposited GaN epitaxial surface has a two-dimensional photonic crystal structure with a hexagonal lattice of 230 nm. The grown structure on the nano-surface shows a Raman shift of the transverse optical phonon mode to <TEX>$569.5\;cm^{-1}$</TEX>, which implies a compressive stress of 0.5 GPa. However, the regrown thin film without the nano-surface shows a free standing mode of <TEX>$567.6\;cm^{-1}$</TEX>, implying no stress. The nanohole surface better preserves the strain energy for pseudo-morphic crystal growth than does a flat plane.
EEG Power Spectra of Children with Dyslexia, Slow Learners, and Normally Reading Children with ADD During Verbal Processing (1994)

EEG power spectra were studied in two poor reader groups (with dyslexia and slow learning) and a normally reading clinic control group (with attention deficit disorder) as the children viewed strings of words and letters (seven categories). The children ranged in age from 7.5 to 12 years; 33 were girls, 86 were boys. Bilateral temporal and parietal sites and four midline sites were used. The major difference between groups was in the low beta band, where the ADD group had greater power at the parietal and midline sites. Also, the slow learner group had marginally greater low beta at the left than right temporal site, with the opposite trend found for the dyslexic and ADD groups. Across groups, power was greater at the right than at the left parietal site in the delta and alpha bands and at the right than at the left temporal site in the low beta band. Stimulus category effects were modest, with some alpha suppression to word strings, relative to letter strings, found in the poor readers. In correlational analyses, the combination of greater low beta and less theta power significantly predicted better reading and spelling. Results indicate that the adequate readers more actively processed the stimuli than did the poor readers.
High copy number of highly similar mariner-like transposons in planarian (Platyhelminthe): evidence for a trans-phyla horizontal transfer. (1995)

Several DNA sequences similar to the mariner element were isolated and characterized in the platyhelminthe Dugesia (Girardia) tigrina. They were 1,288 bp long, flanked by two 32 bp-inverted repeats, and contained a single 339 amino acid open-reading frame (ORF) encoding the transposase. The number of copies of this element is approximately 8,000 per haploid genome, constituting a member of the middle-repetitive DNA of Dugesia tigrina. Sequence analysis of several elements showed a high percentage of conservation between the different copies. Most of them presented an intact ORF and the standard signals of actively expressed genes, which suggests that some of them are or have recently been functional transposons. The high degree of similarity shared with other mariner elements from some arthropods, together with the fact that this element is undetectable in other planarian species, strongly suggests a case of horizontal transfer between these two distant phyla.

Shoulder Rumble Strip Effectiveness: Drift-Off-Road Accident Reductions on the Pennsylvania Turnpike (1997)

To help decrease the number of accidents caused by drowsy drivers, engineers for the Pennsylvania Turnpike developed, and installed on the highway shoulder, an innovative rumble-strip called the Sonic Nap Alert Pattern (SNAP). A distinct warning sound and vibration are produced when tires roll on the strips. When drowsy or inattentive drivers’ vehicles drift to the right, the tires cross this pattern of recessed grooves along the shoulder of the roadway. Various lengths and depths of grooves were tested to select a design with enough sound and vibration to be perceptible in a truck cab and yet not too severe for cars or motorcycles. Design features, testing, and initial results were presented at the TRB Annual Meeting in January 1994. After installation of SNAP, drift-off-road accidents per month decreased by 70 percent. This study reviews those initial results, adds traffic exposure to compare accident rates per vehicle-distance-traveled, adjusts for a decline in all accidents during the years considered, and revises the initially reported accident reduction to 65 percent. Follow-on results are developed for all reportable accidents from 1990 to 1995, singling out those that could be directly affected by SNAP. About 12 percent of all accidents were considered fully susceptible to SNAP treatment. A reduction of 60 percent in treatable accidents, or a decline in rate by 1.43 per 100 million vehicle kilometers, (2.3 accidents per 100 million vehicle miles) was documented for 53 segments totaling 560 km (348 mi) of roadway.
Optical Networking: Past, Present, and Future (2008)

Over the past 25 years, networks have evolved from being relatively static with fairly homogeneous traffic to being more configurable and carrying a heterogeneous array of services. As the applications are ultimately the driver of network evolution, the paper begins with a brief history of circuit, packet, and wave services, along with the development of the corresponding transport layers. The discussion then moves to the evolution of network-node architecture, with an emphasis on the optical-electrical-optical and optical-bypass paradigms. Scalability and cost-effectiveness in meeting network demands are two key factors in the discussion. The evolution of networking equipment, along with the development of the optical control plane, has facilitated a configurable optical layer. The enabling technologies, along with their ramifications, are discussed. Finally, the paper speculates on how capacity might evolve in the future, to handle the undoubtedly new services that are on the horizon.

Optimal distribution for four-station TDOA location system (2010)

At least four stations are needed in time difference of arrival (TDOA) position system locating the moving target in 3D space. Positioning precision is influenced by the distribution of location stations importantly. Firstly a positioning precision model is established and the factors affecting the positioning precision are analyzed in line-of-sight (LOS) environments by studying the principle of TDOA location system. Then they are simulated for eight different models that the 3D curves of position errors and geometric dilution of precision (GDOP) contour maps of four-station. Detailed data showed coverage value of every distribution of location stations. Finally, in this paper, we demonstrated the optimal distribution principle of four-station in 3D space for the moving target based on the links between location precision and the distribution of location stations.
Insomnia and Its Treatment (1985)

Data for this report come from a nationally representative probability sample survey of noninstitutionalized adults, aged 18 to 79 years. The survey, conducted in 1979, found that insomnia afflicts 35% of all adults during the course of a year; about half of these persons experience the problem as serious. Those with serious insomnia tend to be women and older, and they are more likely than others to display high levels of psychic distress and somatic anxiety, symptoms resembling major depression, and multiple health problems. During the year prior to the survey, 2.6% of adults had used a medically prescribed hypnotic. Typically, use occurred on brief occasions, one or two days at a time, or for short durations of regular use lasting less than two weeks. The survey also found a small group of hypnotic users (11% of all users; 0.3% of all adults) who reported using the medication regularly for a year or longer. If we include anxiolytics and antidepressants, 4.3% of adults had used a medically prescribed psychotherapeutic drug that was prescribed for sleep; 3.1% had used an over-the-counter sleeping pill. The majority of serious insomniacs (85%) were untreated by either prescribed or over-the-counter medications.
Bessel-Gaussian electron beams of cylindrically symmetric spin polarization (2011)

Bessel-Gaussian cylindrically symmetric electron beams in spin polarization are reported for the first time. They are shown to be the eigenstates of total angular momentum in the z-direction. But they are neither the eigenstates of spin nor the eigenstates of orbital angular momentum in that direction. Copyright (C) EPLA, 2011
[Definition and significance of the area at risk in myocardial infarct and the ischemic border zone in acute myocardial infarct]. (1986)

Early localisation of infarction, estimation of infarct size and visualisation of metabolic and structural changes is of great importance for the management of acute myocardial infarction. This paper is based on an experimental model using a combination of in-vivo and in-vitro methods that allow the evaluation of the area at risk of infarction, the border zone and its changes over time. The purpose of the study was to characterize the topography and the time course of the border zone. The border zone forms an approximately 2 mm wide margin at the lateral edges of the infarct, with increasing width of the border zone along the subepicardium. Increasing duration of ischemia is associated with a dynamic sequence of events, not only within the area at risk of infarction but also in the peri-ischemic border zone, leading to an expansion of the subepicardial margin due to improved collateral blood flow over time. The area at risk of infarction is characterized by early distinct metabolic changes that were visualized as soon as 90 to 120 seconds following coronary artery occlusion. After 6 hours of occlusion almost the entire area at risk shows signs of irreversible injury due to severe hypoperfusion. The border zone, in contrast, is characterized by only moderate metabolic changes due to greater collateral perfusion (45 to 80% of the regional blood flow in the non-ischemic vascular bed). Several interventions were chosen and evaluated for their effects on the dynamic course of events within the area at risk of infarction and in the border zone. Interventions that have strong myocardial protective effects such as the combination of alpha- and beta-blockade, the application of specific O2-carriers (Perfluorocarbons) and pressure controlled retrograde perfusion via the coronary sinus ("PICSO"), not only reduce infarct size by 20 to 40% of the myocardium at risk of infarction, but also induce substantial topographic, functional and metabolic changes within the border zone.
Integrating the Development of Data Mining and Data Warehouses via Model-driven Engineering (2008)

Abstract. Data mining is one of the most important analysis techniques to automatically extract knowledge from large amount of data. Nowadays, data mining is based on low-level specifications of the employed techniques typically bounded to a specific analysis platform. Therefore, data mining lacks a modelling architecture that allows analysts to consider it as a truly software-engineering process. Bearing in mind this situation, we propose a model-driven approach which is based on (i) a conceptual modelling framework for data mining, and (ii) a set of model transformations to automatically generate both the data under analysis (that is deployed via data-warehousing technology) and the analysis models for data mining (tailored to a specific platform). Thus, analysts can concentrate on understanding the analysis problem via conceptual data-mining models instead of wasting efforts on low-level programming tasks related to the underlying-platform technical details. These time consuming tasks are now entrusted to the model-transformations scaffolding. The feasibility of our approach is shown by means of a hypothetical data-mining scenario where a time series analysis is required.
