HEM Data Processing - A Practical Overview (2000)

The theory of frequency-domain helicopter electromagnetic (HEM) surveys is relatively straightforward, but in practice there are many issues to deal with, both in hardware development and in the software to handle the data processing and analysis (DPA).This paper gives an overview of standard HEM data processing and analysis techniques. This is not new technology, and is intended only to fill a perceived gap in the literature by summarising existing basic DPA procedures for typical HEM datasets.Assuming that the inphase (IP) and quadrature (Q) data for each frequency has been calibrated to parts per million (ppm) during data acquisition, the main procedures are as follows.DATA PROCESSINGApply standard geophysical pre-processing techniques such as parallax (lag) corrections.Remove non-geological noise from the raw data using appropriate filters.Apply drift corrections (zero level corrections). Remove system and instrumentation drift from all EM channels.Archive data and analysis results along with complete documentation of all archived parameters and necessary metadata.DATA ANALYSISCalculate apparent resistivities and depths.Pick anomalies for conductive target body location and analysis. Requires an EM interpreter, but automatic picking provides a first pass.Analyse anomaly targets. Calculate apparent conductances and depths to conductors.Presentation of results; various combinations of:Standard geophysical maps - survey lines etc.;Apparent resistivity and depth maps;Profile maps of IP, Q, resistivity, anomalies;Classified anomaly symbol maps with annotations e.g. Identification letters, apparent depths, etc.);Detailed multichannel profile plots for each survey line.Conductivity depth sections.Anomaly report.
Graded transcriptional response to different concentrations of a single transactivator (1998)

Threshold mechanisms of transcriptional activation are thought to be critical for translating continuous gradients of extracellular signals into discrete all-or-none cellular responses, such as mitogenesis and differentiation. Indeed, unequivocal evidence for a graded transcriptional response in which the concentration of inducer directly correlates with the level of gene expression in individual eukaryotic cells is lacking. By using a novel binary tetracycline regulatable retroviral vector system, we observed a graded rather than a threshold mechanism of transcriptional activation in two different model systems. When polyclonal populations of cells were analyzed at the single cell level, a dose-dependent, stepwise increase in expression of the reporter gene, green fluorescent protein (GFP), was observed by fluorescence-activated cell sorting. These data provide evidence that, in addition to the generally observed all-or-none switch, the basal transcription machinery also can respond proportionally to changes in concentration of extracellular inducers and trancriptional activators.
A novel sequence in the type IV collagen promoter binds nuclear proteins from Engelbreth-Holm-Swarm tumor. (1992)

The production of extracellular matrix proteins is an important element of tumor formation, and alterations in matrix protein metabolism may be critical to the process of tumor metastasis. Abundant expression of type IV collagen, the major structural protein of the basement membrane, is characteristic of the Engelbreth-Holm-Swarm (EHS) mouse sarcoma. In the present study, we evaluated mechanisms of transcriptional regulation of type IV collagen genes by analysing nuclear factors that bind to the promoter region. Gel mobility-shift assays indicated that specific proteins from EHS tumor bound the promoter and generated several unique shift patterns. The specific sequences to which these proteins bound were determined using DNAase I protection assays. DNA-binding proteins protected two regions from DNAase I digestion. The first region was similar to a GC box, the binding site for the transcription factor Sp1. The other footprint was a 30-bp region that contained the novel sequence motif, 'CCCTCCC' present in several other extracellular matrix promoters. Nuclear extracts isolated from tissues that variably express type IV collagen bound to this protected sequence with distinctly different shift patterns. Furthermore, in highly expressing tissues, unlabeled oligonucleotides containing the 'CCCTCCC' motif effectively inhibited nuclear protein binding with the entire promoter. Thus, it is likely that a novel protein or protein complex binds to these sequences. Furthermore, these sequences appear to be unique to the genes that encode basement membrane proteins, suggesting a specific role in their regulation.
Virtual machine consolidation in cloud data centers using ACO metaheuristic (2014)

In this paper, we propose the AVVMC VM consolidation scheme that focuses on balanced resource utilization of servers across different computing resources (CPU, memory, and network I/O) with the goal of minimizing power consumption and resource wastage. Since the VM consolidation problem is strictly NP-hard and computationally infeasible for large data centers, we propose adaptation and integration of the Ant Colony Optimization (ACO) metaheuristic with balanced usage of computing resources based on vector algebra. Our simulation results show that AVVMC outperforms existing methods and achieves improvement in both energy consumption and resource wastage reduction. © 2014 Springer International Publishing Switzerland.
Adding tuples to Java: a study in lightweight data structures (2005)

Abstract Java classes are very flexible, but this comes at a price. The main cost is that every class instance must be dynamically allocated. Also, their access by reference introduces pointer de‐references and complicates program analysis. These costs are particularly burdensome for small, ubiquitous data structures such as coordinates and state vectors. For such data structures a lightweight representation is desirable, allowing such data to be handled directly, similar to primitive types. A number of proposals introduce restricted or mutated variants of standard Java classes that could serve as lightweight representation, but the impact of these proposals has never been studied. Since we have implemented a Java compiler with lightweight data structures we are in a good position to do this evaluation. Our lightweight data structures are tuples . As we will show, using tuples can result in significant performance gains: for a number of existing benchmark programs we gain more than 50% in performance relative to our own compiler, and more than 20% relative to Sun's Hotspot 1.4 compiler. We expect similar performance gains for other implementations of lightweight data structures. With respect to the expressiveness of Java, lightweight variants of standard Java classes have little impact. In contrast, tuples add a different language construct that, as we will show, can lead to substantially more concise program code. Copyright © 2005 John Wiley & Sons, Ltd.
Sequence-modification based collision-free motion planning of multiple robots workcell (2016)

This work is inspired by the problem of planning multiple robots in a shared workspace. The goal is to find out a sequence order for coordinating the paths of robots so as to avoid collisions among them and deadlocks, that is, situations where each robot is waiting for the other to proceed. We assume that the workcell is known and the paths of robots can be planned in advance and all the robots move synchronously. These assumptions are good models of many tasks. The coordination is achieved by introducing improved A* heuristic algorithm for continuous state sequence planning in high dimensional space. The proposed method consist of two steps: 1) path planning for the robots, which taking into account avoidance of collision between the robots and the environment; 2) calculating all the possible colliding state and translating the coordinating problem into scheduling the path segments. Experimental cases are shown for the proposed algorithm and for their implementations. The results of the planning method can be applied to the industrial applications.
Enteral Feeding Misconnections: An Update (2009)

Enteral misconnections are defined as inadvertent connections between enteral feeding systems and nonenteral systems such as intravascular lines, peritoneal dialysis catheters, tracheostomy tube cuffs, medical gas tubing, and so on. Sentinel event data and causative factors are outlined along with potential solutions to prevent such medical errors. The solutions can be grouped into 3 areas: (1) education, awareness, and human factors; (2) purchasing strategies; and (3) design changes. Updates on safety innovations and programs are presented.
Artificial Intelligence-Aided Receiver for a CP-Free OFDM System: Design, Simulation, and Experimental Test (2019)

Orthogonal frequency division multiplexing (OFDM), usually with sufficient cyclic prefix (CP), has been widely applied in various communication systems. The CP in OFDM consumes additional resource and reduces spectrum and energy efficiency. However, channel estimation and signal detection are very challenging for CP-free OFDM systems. In this paper, we propose a novel artificial intelligence (AI)-aided receiver (AI receiver) for a CP-free OFDM system. The AI receiver includes a channel estimation neural network (CE-NET) and a signal detection neural network based on orthogonal approximate message passing (OAMP), called OAMP-NET. The CE-NET is initialized by the least-square channel estimation algorithm and refined by a linear minimum mean-squared error neural network. The OAMP-NET is established by unfolding the iterative OAMP algorithm and adding several trainable parameters to improve the detection performance. We first investigate their performance under different channel models through extensive simulation and then establish a real transmission system using a 5G rapid prototyping system for an over-the-air (OTA) test. Based on our study, the AI receiver can estimate time-varying channels with a single training phase. It also has great robustness to various imperfections and has better performance than those competitive algorithms, especially for high-order modulation. The OTA test further verifies its feasibility to real environments and indicates its potential for future communications systems.
Foot-Eye Calibration for Mobile Robots (2007)

To establish a complete mobile robot system based on visual navigation,a footeye calibration method is proposed for mobile robots.A planar mirror with some given marker points is employed as an intermediary to calibrate the Euclidean transformations between camera coordinate frame and specular image coordinate frame,between camera coordinate frame and mirror coordinate frame,between specular image coordinate frame and mirror coordinate frame and between robot-centered coordinate frame and mirror coordinate frame.Subsequently,rigid transformation from camera coordinate frame to robot-centered coordinate frame is established,realizing the foot-eye calibration for mobile robots.Experimental results indicate that the presented method is simple and effective.Since it is free of expensive physical setup and complex procedure,it is suitable for field operating.
Low-complexity waveform coding via alphabet and sample-set partitioning (2002)

We propose a new low-complexity entropy-coding method to be used for coding waveform signals. It is based on the combination of two schemes: (1) an alphabet partitioning method to reduce the complexity of the entropy-coding process; (2) a new recursive set partitioning entropy-coding process that achieves rates smaller than first order entropy even with fast Huffman adaptive codecs. Numerical results with its application for lossy and loss-less image compression show the efficacy of the new method, comparable to the best known methods.
Investigation of on-chip high temperature annealing of PMOS dosimeters (1996)

Radiation sensitive pMOS dosimeters can measure only to a maximum dose which is determined by the type, sensitivity and irradiation conditions of the RADFET. On reaching the maximum dose, the dosimeters normally have to be replaced. The aim of this work is to study the feasibility of using on-chip poly-resistor heaters to anneal the dosimeters back to their pre-irradiation threshold voltage. This study shows that on-chip heating is a viable option to achieve post-irradiation annealing, and that the fading characteristics obtained agree with those of oven annealing from a previous study which was carried out on the NMRC RADFETs.
Elevated Serum Levels of Interferon‐γ–Inducible Protein–10 in Patients Coinfected with Hepatitis C Virus and HIV (2007)

Coinfection with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) is associated with an accelerated course of HCV infection and a faster progression to severe liver disease. We have investigated whether the development of liver disease in coinfected patients is associated with specific chemokine and cytokine production. Four cohorts--HCV/HIV-coinfected patients, HCV-monoinfected patients, HIV-monoinfected patients, and healthy control subjects--were studied. Serum levels of the 10-kDa interferon- gamma -inducible protein (IP-10) were higher in all 3 groups of infected patients than in control subjects (P<.0001). HCV/HIV-coinfected patients had significantly higher IP-10 levels than monoinfected patients. In HCV-monoinfected patients, liver fibrosis scores and liver enzyme levels were positively correlated with IP-10 levels. Elevated IP-10 levels are associated with and may contribute to liver damage in both HCV-monoinfected and HCV/HIV-coinfected patients.
Formation and Reversion of Streptomycete Protoplasts: Cultural Condition and Morphological Study (1974)

SUMMARY: Cultural conditions for forming and stabilizing protoplasts of Streptomyces griseus and S. venezuelae were studied by reference to the number of protoplasts formed, leakage from protoplasts and reversion rate. Effective formation and stabilization of the protoplasts was accomplished by using a hypertonic medium containing 10 mm-MgCl2 and 25 mm-CaCl2. Electron microscopy showed that the protoplasts of S. griseus, when prepared in the above medium, formed vesicles on the cytoplasmic membrane or out of the protoplasts, but when prepared in a medium with 3 mm-MgCl2 and 3 mm-CaCl2 they provided few such vesicles. The reversion of protoplasts to the normal filamentous state was examined by the growth on various synthetic agar media. A high reversion rate was obtained by incubating the protoplasts on a hypertonic agar medium containing 20 or 50 mm-MgCl2, 50 or 20 mm-CaCl2, 0·44 or 0·22 mm-phosphate and 0·01 % Casamino acids. Combinations of appropriate concentrations of MgCl2 and CaCl2 were significantly effective in the reversion as well as in the stability of protoplasts. The concentration of phosphate should be adjusted to 0·44 or 0·22 mm. Casamino acids enhanced both growth and reversion rates. The reversion of protoplasts of Streptomyces griseus was followed by using phase-contrast microscopy. The protoplasts incubated on medium R1 enlarged to about 40 µm and then generated filamentous hyphae from the periphery.
Bactericidal activity of antimicrobial coated polyurethane sleeves for external fixation pins (2003)

This study was conducted to assess the potential of gentamicin coated polyurethane sleeves to inhibit bacterial colonization on external fixation pins and wires. These antimicrobial sleeves have been designed to be fitted over the pins and wires, at the time of surgery, as a prophylactic approach to combat the major complication of external fixation treatment, pin tract infection. Elution testing was conducted to estimate the amount of gentamicin released into the pin tract. These gentamicin concentrations were compared to the gentamicin minimal inhibitory concentration (MIC) level for common pin tract pathogens. Elution testing revealed that the gentamicin coated polyurethane sleeves released significant quantities of the antibiotic for up to 26 weeks. The initial bolus release was characterized by predicted pin tract gentamicin concentrations of >80 microg/ml at the 2 h and 1 day elution time points. These amounts of gentamicin, delivered directly to the pin tract, are far beyond those that could be achieved via oral or intravenous administration. Furthermore, the expected concentration of gentamicin in the pin tract remained above the National Committee for Clinical Laboratory Standards (NCCLS) MIC breakpoint of 4 microg/ml, [Performance standards for antimicrobial susceptibility testing: twelfth informational supplement M100-S12, NCCLS, Wayne, PA, 2002], for at least 20 weeks. Data from the SENTRY antimicrobial surveillance program (1997-2002) established a high level of bactericidal activity for gentamicin, with 83.1% of the common pin tract pathogen isolates found to be susceptible to the antibiotic. The initial burst and subsequent long-term sustained local delivery of effective amounts of gentamicin from the antimicrobial sleeves would be expected to inhibit bacterial colonization on external fixation pins and wires. This inhibition of bacterial colonization should substantially reduce the incidence of pin tract infection, and improve the overall outcome and cost effectiveness of external fixation fracture management.
An application framework for implicit sentiment human-centered tagging using attributed affect (2013)

In this paper, a novel framework for implicit sentiment image tagging and retrieval is presented, based on the concept of attributed affect. The user's affective response is recorded and analyzed to provide an appropriate affective label, while eye gaze is monitored in order to identify a specific object depicted in the scene, which is attributed as the cause of the user's current state of core affect. Through this procedure, automatic tagging of content, as well as retrieval based on personal preferences is possible. Our experiments show that our framework successfully channels behavioral tags (in the form of affective labels) to the data tagging and retrieval loop, even when applied in the context of a cost-efficient, widely available hardware setup, that uses a single low resolution webcam mounted on a standard modern computer system.
MASS-PRODUCTION OF BIOCATALYST-ENTRAPPING ALGINATE GEL PARTICLES BY A FORCED OSCILLATION METHOD (1993)

Abstract A forced oscillation method applying reverse-piezo electric effect has been proposed for mass-production of biocatalyst-entrapping polymer gel particles. A jet of aqueous alginate solution flowing out through an orifice was disintegrated into droplets by an oscillating pressure which was exerted by a ceramic plate vibrated by the reverse-piezo electric effect. The droplets formed were immediately solidified into gel particles in calcium chloride solution. The particle production rate by the method was up to 270 particles s−1 or 1 × 10−6m3.s−1 The size of the particles produced were down to I mm depending on the applied frequency. The smallest matrix size of the gel's polymer network was estimated to be around 5 nm. The method was applied for immobilization of yeast cells. The diameter of immobilized particles was 2.5 mm. The immobilized yeast grew well in the particle. The damage of yeast cells caused by the immobilization was not remarkable
Heads Up and Camera Down: A Vision-Based Tracking Modality for Mobile Mixed Reality (2008)

Anywhere Augmentation pursues the goal of lowering the initial investment of time and money necessary to participate in mixed reality work, bridging the gap between researchers in the field and regular computer users. Our paper contributes to this goal by introducing the GroundCam, a cheap tracking modality with no significant setup necessary. By itself, the GroundCam provides high frequency, high resolution relative position information similar to an inertial navigation system, but with significantly less drift. We present the design and implementation of the GroundCam, analyze the impact of several design and run-time factors on tracking accuracy, and consider the implications of extending our GroundCam to different hardware configurations. Motivated by the performance analysis, we developed a hybrid tracker that couples the GroundCam with a wide area tracking modality via a complementary Kalman filter, resulting in a powerful base for indoor and outdoor mobile mixed reality work. To conclude, the performance of the hybrid tracker and its utility within mixed reality applications is discussed.

Meta-analysis of amyloid-cognition relations in cognitively normal older adults (2013)

Based on this meta-analytic survey of the literature, increased amyloid burden has small but nontrivial associations with specific domains of cognitive performance in individuals who are currently cognitively normal. These associations may be useful for identifying preclinical Alzheimer disease or developing clinical outcome measures.
New ultra-wideband filters based on tuning forks shape and CSRRs (2014)

In this work, the tuning forks (TFs) shape and complementary split ring resonators (CSRRs) are the tools used to present new UWB microwave filters. Two tuning forks are printed on the upper side of the microstrip line covering the host transmission lines. The filter bandwidth containing tuning forks is ultra-wide and equal to 11.8GHz operating at 6.1GHz center frequency. A novel method to upgrade the matching between the host transmission lines and the CSRRs is proposed as well. The bandwidths of the developed filters containing tuning forks with the presence of different CSRRs at different designs are 10, 6.8, 5.5 and 4.7GHz at 5.4, 3.6, 3 and 2.55GHz center frequency, respectively. The negative permittivity metamaterial is made of CSRRs which are etched in the lower side of the microstrip line. These metamaterial filters combine negative characteristics of permeability and permittivity which are created by using TF and CSRRs components respectively to create an UWB response with better performance and size reduction. The simulation results showed that the filters have composite right/left handed (CRLH) behavior with insertion losses less than 1dB and suitable average rejections.
