Lost node recovery in a city-wide wireless sensor network using adaptive preselect filtering (2009)

In this paper, we describe our efforts to combat lost nodes in wireless sensor networks. Often times, the wireless sensor network is limited by interference. Specifically, in a practical setting it was found that lost nodes were caused by location of the sensor nodes in relative proximity to cellular broadcasting stations. This effect was modeled and combated using adaptable front end filtering to show the impact of an intelligent front end system as opposed to the more traditional static preselect filtering commonly applied. Using real system parameters, greater than 10% improvement in the packet reception rate compared to a static filter was achieved by adjusting the filtering to the surrounding environment. Only slight tuning was needed to be able to achieve the result and this indicates the traditional method of using a static preselect filter is suboptimal.
Induction generator model in phase coordinates for fault ride-through capability studies of wind turbines (2007)

A phase coordinates induction generator model with time varying electrical parameters as influenced by magnetic saturation and rotor deep bar effects, is presented in this paper. The model exhibits a perphase formulation, uses standard data sheet for characterization of the electrical parameters, is developed in C-code and interfaced with Matlab/Simulink through an S-Function. Saturation uses a direct non-linear magnetizing inductance versus input voltage function. Deep-bar effect is evaluated using voltage reliant correction factors to make both rotor resistance and leakage inductance dependent on the rotor speed. The investigation compares the behaviour of three models in the presence of external faults, namely the “classical„ DQ model, a phase coordinates model with constant parameters and the proposed phase coordinates model with time varying rotor and magnetic electrical parameters. Case studies are conducted in a representative sized system and results show aptness of the proposed model over other two models. This approach is also constructive to support grid code requirements.
Thermodynamic Theory of Light Ion Beam Propagation in a Plasma (1983)

Propagation of a light ion beam in a plasma is investigated theoretically. The basic principle determining the steady state of the beam transport in a plasma is ascertained from the view points of the theory of the irreversible processes. As a preliminary work to discuss the collisional plasma, we consider a state in which the entropy production vanishes and obtain an extended result of Chen and Davidson to include the current due to the drift of the plasma electrons. Two extreme cases are considered: ( i ) No rotation of the beam around the axis of symmetry or complete neutralization of azimuthal beam current by the plasma electron. ( i i ) Complete balancing of the electrostatic repulsive force on a beam ion and the magnetically pinching force due to the axial beam current. It is shown that the distribution of ions in a rotational ion beam is given by the Bennett type, provided the current is over-neutralized azimuthally.
Development of Robot Remote Teaching System Based on Estimated Wrist Position by Inertial Sensor (2021)

Japanese society is rapidly aging, and its birthrate is low, leading to a reduction of the working population. Therefore, industrial robots are increasingly expected to serve as substitutes for human beings. Conventional teaching methods with robots include remote teaching and direct teaching. These teaching methods have problems in terms of difficulty teaching sensibly and teacher safety. In order to solve these problems, sensuous but remote teaching is ideal for the teacher. In this research, We propose a remote and sensuous teaching system by inertial sensors. We extracted the target position and posture information of the robot to be taught using inertial sensors and applied our system to the actual robot. In this paper, We attach one inertial sensor to trapezius, upper arm and forearm to estimate the trajectory of the wrist. And the 6 DoF robot arm remote teaching system was built. To verify the effectiveness of this system, wrist estimation position accuracy verification experiment, trajectory following experiment, position control experiment, and comparison experiment with other teaching device have conducted. As a result, the effectiveness of remote teaching system by inertial sensors was shown.
Improving drug delivery technology for treating neurodegenerative diseases (2016)

Current treatments do not fully address the biological, drug and therapeutic factors faced. This has led to the development of vogue treatments such as nose-to-brain technologies, bio-engineered systems, fusion protein chaperones, stem cells, gene therapy, use of natural compounds, neuroprotectants and even vaccines. However, failure of these treatments is mainly due to the BBB and non-specific delivery in the brain. In order to increase neuroavailability various advanced drug delivery systems provide promising alternatives that are able to augment the treatment of Alzheimer's disease and Parkinson's disease. However, much work is still required in this field beyond the preclinical testing phase.
EVIDENCE THAT THE ANTIBIOTIC CIPROFLOXACIN COUNTERACTS CYCLOSPORINE-DEPENDENT SUPPRESSION OF CYTOKINE PRODUCTION1 (1994)

The fluoroquinolone antibiotic ciprofloxacin (cipro) has been reported to upregulate interleukin 2 and interferon-gamma production in lectin-stimulated lymphocytes. The aim of this study was to elucidate whether cipro and the immunosuppressive agent CsA have antagonistic action on cytokine synthesis. Accumulation of IL-2 and IFN-gamma protein and mRNA were analyzed in polyclonally (PHA or Con A) or alloantigen-stimulated human peripheral blood lymphocytes. CsA added simultaneously with PHA partially blocked cytokine synthesis. The present study also shows that cipro supplemented with CsA and PHA resulted in significant higher concentrations of IL-2 (up to 60 times) and IFN-gamma (4.3 times) as compared with PHA and CsA alone. Similar results were obtained with primary mixed lymphocyte reactions. In parallel, a greater amount of IL-2 and IFN-gamma mRNA was observed in lymphocytes incubated with both cipro and CsA as compared with CsA alone. Our results reveal that CsA-dependent inhibition of both IL-2 and IFN-gamma expression is counteracted by high concentrations of cipro. These findings may be of importance in clinical transplantation.

A Non-Contact Imaging-Based Approach to Detecting Stage I Pressure Ulcers (2006)

This paper describes a non-contact imaging-based method to detect stage I pressure ulcers over a wide range of melanin levels. Two approaches were explored: the first used broad and narrow band visible spectrum imaging, and the second used near infrared (NIR) imaging. Preliminary results are presented together with results of numerical analysis of different erythema indices derived from the visible spectrum images. The results have shown that a low-cost imaging-based approach to detecting pressure ulcers is feasible and can yield promising results when applied to subjects with darker skin pigmentation.
A Solution-Phase Chemical Approach to a New Crystal Structure of Cobalt (1999)

Kinetic control of crystal growth in the presence of a coordinating ligand is critical for the formation of a new structure of elemental cobalt (ε-cobalt, the unit cell with the two different types of cobalt atoms is shown), which was discovered upon analyzing the metallic powder produced by the thermal decomposition of [Co2(CO)8] in solution in the presence of trioctylphosphane oxide [TOPO, Eq. (1)].
Quantum Mechanical/Molecular Mechanical Modeling Finds Diels−Alder Reactions Are Accelerated Less on the Surface of Water Than in Water (2010)

Quantum and molecular mechanics calculations for the Diels-Alder reactions of cyclopentadiene with 1,4-naphthoquinone, methyl vinyl ketone, and acrylonitrile have been carried out at the vacuum-water interface and in the gas phase. In conjunction with previous studies of these cycloadditions in dilute solution, a more complete picture of aqueous environmental effects emerges with implications for the origin of observed rate accelerations using heterogeneous aqueous suspensions, "on water" conditions. The pure TIP4P water slab maintains the bulk density and hydrogen-bonding properties in central water layers. The bulk region merges to vacuum over a ca. 5 A band with progressive diminution of the density and hydrogen bonding. The relative free energies of activation and transition structures for the reactions at the interface are found to be intermediate between those calculated in the gas phase and in bulk water; i.e., for the reaction with 1,4-naphthoquinone, the DeltaDeltaG(++) values relative to the gas phase are -3.6 and -7.3 kcal/mol at the interface and in bulk water, respectively. Thus, the results do not support the notion that a water surface is more effective than bulk water for catalysis of such pericyclic reactions. The trend is in qualitative agreement with expectations based on density considerations and estimates of experimental rate constants for the gas phase, a heterogeneous aqueous suspension, and a dilute aqueous solution for the reaction of cyclopentadiene with methyl vinyl ketone. Computed energy pair distributions reveal a uniform loss of 0.5-1.0 hydrogen bond for the reactants and transition states in progressing from bulk water to the vacuum-water interface. Orientational effects are apparent at the surface; e.g., the carbonyl group in the methyl vinyl ketone transition structure is preferentially oriented into the surface. Also, the transition structure for the 1,4-naphthoquinone case is buried more in the surface, and the free energy of activation for this reaction is most similar to the result in bulk water.
Quantification of Genetically Modified Soybean by Quenching Probe Polymerase Chain Reaction (2005)

Quenching probe (QProbe) polymerase chain reaction (PCR) is a simple and cost-effective real-time PCR assay in comparison with other real-time PCR assays such as the TaqMan assay. We used QProbe-PCR to quantify genetically modified (GM) soybean (Roundup Ready soybean). We designed event-specific QProbes for Le1 (soy endogenous gene) and RRS (recombinant gene), and we quantified certified reference materials containing 0.1, 0.5, 1, 2, and 5% GM soybean. The TaqMan assay was also applied to the same samples, and the results were compared. The accuracy of QProbe-PCR was similar to that of TaqMan assay. When GM soybean content was 0.5% or more, the relative standard deviations of QProbe-PCR were less than 20%. QProbe-PCR is sensitive enough to monitor labeling systems and has acceptable levels of accuracy and precision.
Structured light enhanced entoptic stimuli for vision science applications (2023)

The dichroic macular pigment in the Henle fiber layer in the fovea enables humans to perceive entoptic phenomena when viewing polarized blue light. In the standard case of linearly polarized stimuli, a faint bowtie-like pattern known as the Haidinger's brush appears in the central point of fixation. As the shape and clarity of the perceived signal is directly related to the health of the macula, Haidinger's brush has been used as a diagnostic marker in studies of early stage macular degeneration and central field visual dysfunction. However, due to the weak nature of the perceived signal the perception of the Haidinger's brush has not been integrated with modern clinical methods. Recent attempts have been made to increase the strength of the perceived signal by employing structured light with spatially varying polarization profiles. Here we review the advancements with the structured light stimuli and describe the current challenges and future prospects.

Surface water retardation around single-chain polymeric nanoparticles: critical for catalytic function? (2015)

A library of water-soluble dynamic single-chain polymeric nanoparticles (SCPN) was prepared using a controlled radical polymerisation technique followed by the introduction of functional groups, including probes at targeted positions. The combined tools of electron paramagnetic resonance (EPR) and Overhauser dynamic nuclear polarization (ODNP) reveal that these SCPNs have structural and surface hydration properties resembling that of enzymes.

Proteomic Analysis of the Palmitate-induced Myotube Secretome Reveals Involvement of the Annexin A1-Formyl Peptide Receptor 2 (FPR2) Pathway in Insulin Resistance* (2015)

Elevated levels of the free fatty acid palmitate are found in the plasma of obese patients and induce insulin resistance. Skeletal muscle secretes myokines as extracellular signaling mediators in response to pathophysiological conditions. Here, we identified and characterized the skeletal muscle secretome in response to palmitate-induced insulin resistance. Using a quantitative proteomic approach, we identified 36 secretory proteins modulated by palmitate-induced insulin resistance. Bioinformatics analysis revealed that palmitate-induced insulin resistance induced cellular stress and modulated secretory events. We found that the decrease in the level of annexin A1, a secretory protein, depended on palmitate, and that annexin A1 and its receptor, formyl peptide receptor 2 agonist, played a protective role in the palmitate-induced insulin resistance of L6 myotubes through PKC-θ modulation. In mice fed with a high-fat diet, treatment with the formyl peptide receptor 2 agonist improved systemic insulin sensitivity. Thus, we identified myokine candidates modulated by palmitate-induced insulin resistance and found that the annexin A1- formyl peptide receptor 2 pathway mediated the insulin resistance of skeletal muscle, as well as systemic insulin sensitivity.
Effects of radiation-induced carbon contamination on the performance of an EUV lithographic optic (2003)

Carbon deposition in EUVL is known to occur when optical surfaces in a hydrocarbon environment are exposed to EUV light. Carbon contamination on EUV optical elements affects both the absorption and phase of the reflected light. Because the carbon deposition alters the phase structure of the reflected EUV light it effectively alters the figure of these optics and, thus, the aberrations as well. Absorption by deposited carbon not only reduces throughput but also leads to apodisation of the pupil, which in turn affects imaging performance.
Evolutional agents: field oriented programming language, Flage (2002)

We propose two new concepts, evolutional agent and field. The main purpose of the work is to provide a framework for building software which adapts to changes of requirements autonomously. In open networks, the adaptability to changes of requirements or environments is essential, while there are many free applications and components to serve various requirements. Focusing on this point, we introduce concurrent objects with meta-base architecture, agents, and fields, another kind of object. In our model, adaptive agents, called evolutional agents, adapt to changes by traversing a network and acquiring components as their own functions. Fields are receptacles of software components in networks. Agents evolve into enhanced ones by traveling to fields and acquiring components from the fields. Flage is a framework for building the software architecture based on these concepts.
Backyard benefits? A cross-sectional study of yard size and greenness and children’s physical activity and outdoor play (2021)

In our study of young children residing in higher socio-economic areas of Melbourne yard characteristics did not appear to have a major impact on children's physical activity. Larger studies with greater variation in yard characteristics and identification of activity location are needed to better understand the importance of home outdoor spaces and guide sustainable city planning.
Mixing RIS-Assisted Sources with FSO Link (2020)

This letter proposes and evaluates the performance of reconfigurable intelligent surface (RIS)-assisted source multiuser mixed radio frequency (RF)/free space optical (FSO) relay network with opportunistic user scheduling. Closed-form analytical approximations are derived for the outage probability and average symbol error probability (ASEP) assuming Rayleigh and Gamma-Gamma fading models for the RF and FSO channels, respectively. Moreover, to gain more insight into the system behavior, the system is studied at the high signal-to-noise ratio (SNR) regime whereby the diversity order and coding gain are derived and analyzed. The results illustrate that the system performance is dominated by the worst hop and that the diversity order is equal to Gd = min(KN,alpha,beta,zeta^2), where K is the number of RF users, N is the number of reflecting elements at each user, alpha and beta are the atmospheric turbulence parameters of the FSO link, and zeta^2 is a measure for the alignment quality of the FSO link. In addition, findings show that for the same diversity order, N is more impactful on the system performance than K through the coding gain Gc.
225 km repeaterless 10 Gb/s transmission over uncompensated SSMF using duobinary modulation and Raman amplification (2002)

In this paper, we investigate the maximum transmission distance using optical duobinary modulation in combination with Raman amplification without any inline amplifiers or dispersion compensating devices. We demonstrate 225 km error free transmission on standard single mode fiber (SSMF) which is, to the best of our knowledge, the longest reported distance for dispersion uncompensated 10 Gb/s repeaterless transmission experiments on SSMF.
The unique implications of brood selection for genetic programming (2002)

In nature it is common for organisms, as quoted from (Kozlowski and Steams, 1989), to "produce many offspring and then neglect, abort, resorb, or eat some of them, or allow them to eat each other." This phenomenon is known variously as soft selection, brood selection, spontaneous abortion, and a host of other terms depending upon both semantics and the stage of ontogeny and/or development at which the culling of offspring takes place. The bottom line of this behavior in nature is the reduction of parental resource investment in offspring who are potentially less fit than others. The use of brood selection in genetic programming was first suggested in (Altenberg, 1993, 1994) as a method to select for representations of CTP with greater evolvability under recombination. We show that brood selection has benefits to artificial genetic systems analogous to those it confers upon biological genetic systems, specifically in terms of conservation of CPU investment and memory investment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Life Evaluation of a Lanthanum Hexaboride Hollow Cathode for High-Power Hall Thruster (2017)

Lanthanum hexaboride hollow cathodes have been in development in the United States for electric thruster applications for nearly 15 years. The life of the lanthanum-hexaboride insert in these hollow cathodes is projected to range from 10 kh to over 100 kh based on insert evaporation calculations. A detailed investigation of the life of a 1.5 cm outside-diameter lanthanum-hexaboride hollow cathode has been made. This cathode can provide discharge currents between 5 and 100 A and has an estimated lifetime in excess of 50 kh depending on discharge current and mass flow rate. The insert evaporation rate is determined from a 4000 h discharge wear test of a laboratory model cathode, where insert weight-loss measurements were made at the start, middle, and end of the test. Detailed insert temperature and plasma measurements are used in a one-dimensional disk evaporation model that accommodates the insert temperature profiles found with different discharge currents, flow rates, and cathode orifice diameters, to predict the insert life. The results suggest that insert outgassing is significant early in life, and lanthanum redeposition reduces the net evaporation rate and extends the cathode life.
Technique for monolithically integrating GaAs/AlGaAs lasers of different wavelengths (1989)

Lasers that operate at wavelengths differing by 40 nm have been fabricated from two different regions of a single wafer by a process using molecular‐beam epitaxy. The process consists of controlling the thicknesses of the quantum wells in the regions which form the active areas of the lasers. The control is accomplished by manipulating the Ga sticking coefficient through local variations of the substrate temperature during the growth process. This process could lead to a variety of important developments in GaAs‐based technology such as multiwavelength optical interconnects.
Topical Chlorhexidine Diphosphanilate (WP-973) in Burn Wound Sepsis (1984)

We studied the diphosphanilate salt of chlorhexidine (WP-973), as a 2% cream, for therapeutic activity in two rat models of fatal burn wound infection. Control treatments were infection and placebo cream; infection only; infection and 1% sulfadiazine silver; and burning only. Activity against Pseudomonas aeruginosa or Proteus mirabilis was tested in surface-inoculated rats with 20% scalds. Treatments were initiated 24 hours or four hours, respectively, after inoculation. Pseudomonas-infected rats were treated once a day for ten days. Proteus-infected rats were treated once a day for five days. In these experimental models, chlorhexidine diphosphanilate was equal to silver sulfadiazine, an established topical chemotherapeutic agent. In vitro activity was examined using bacteremia isolates from 65 burned patients. Using agar diffusion trench plates, chlorhexidine diphosphanilate was active against all strains. No evidence of cross-resistance between sulfonamide and chlorhexidine diphosphanilate or its components was observed.

Processing and Properties of Advanced Ceramic Abradable Coatings (2007)

Abstract Abradable seals have been used in jet engines since the late 1960's. Today abradable seals are seeing applications not only in low pressure and high pressure sections of the compressor but also in the high pressure turbine module of jet engines and are gaining ever more attention in industrial gas turbines. Thermal spraying is a relative simple and cost effective means to apply abradable seals. These work by minimizing gaps between rotating and stationary components by allowing the rotating parts to cut into the stationary ones. The types of coatings employed are zirconia based abradable material systems with polymer and, in some cases, hexagonal boron nitride additions. The coatings are designed to work at service temperatures of up to 1200 °C. The objective of this paper is to review various types of commercial and experimental ceramic abradable systems and to assess their performance profiles. The paper will review yttria stabilized zirconia based systems with modified polymer additions and with variable particle sizes of the ceramic phase. Alternative stabilizers and their influence on key coating properties such as thermal shock resistance and abradability will be studied. The paper will also review the influence of plasma spray parameters on coating properties and study the general influence of coating porosity on coating erosion properties and abradability.
