Generation and evolution of the terahertz vortex beam (2013)

Based on the complementary V-shaped antenna structure, ultrathin vortex phase plates are designed to achieve the terahertz (THz) optical vortices with different topological charges. Utilizing a THz holographic imaging system, the two dimensional complex field information of the generated THz vortex beam with the topological number l=1 is directly obtained. Its far field propagation properties are analyzed in detail, including the rotation, the twist direction, and the Gouy phase shift of the vortex phase. An analytic Laguerre-Gaussian mode is used to simulate and explain the measured phenomena. The experimental and simulation results overlap each other very well.
Resistance to activated protein C: a major cause of inherited thrombophilia. (1997)

Blood coagulation proteins play a major role in the development of pathological venous and arterial thrombosis. Inherited disorders of thrombosis are due to deficiencies of the anticoagulant proteins antithrombin, protein C, and protein S in 10% to 15% of individuals that present with venous thrombosis. A recently described cause of venous thrombosis is characterized by a poor response to activated protein C. In 90% of cases the activated protein C resistance is attributable to a mutation in the factor V gene (factor V Leiden). Activated protein C resistance is found in up to 7% of the Caucasian population but essentially unseen in other races. Activated protein C resistance is associated with a 5 to 10X increased risk of venous thrombosis in individuals that are heterozygous for the defect and a 50 to 100X increased risk in those individuals that are homozygous for factor V Leiden. Activated protein C resistance can be detected in the laboratory by modifications of the activated partial thromboplastin time assay. This assay is easy to perform and can be automated for a variety of instruments. Confirmation of the mutation of the factor V gene is accomplished through polymerase chain reactions that require DNA extraction from the patient's blood sample. Global assays that reflect the functionality of the protein C pathway have recently been introduced to the marketplace.
Fuel Cell Hybrid Taxi Well-to-Wheel Life-Cycle Analysis (2010)

In a collaboration led by hydrogen fuel cell developer Intelligent Energy, a fleet of classic London cabs fitted out with hydrogen fuel cell power systems will be produced, with the objective of having a small fleet ready for full road trials in time for the 2012 Olympics. This research develops the Well-to-Wheel (WTW) Life-Cycle Analysis (LCA) for two hydrogen powered vehicle powertrain options (fuel cell plug-in hybrid vehicle, PHEV-FC; and fuel cell hybrid vehicle, HEV-FC), in comparison to the conventional ICE Diesel Taxi and a full electric vehicle (EV). In terms of energy pathways, the introduction of these different vehicle technologies is associated with alternative energy sources in a Taxi fleet so the following fuel pathways are compared: diesel, considering the average European diesel fuel characteristics; electricity, considering the 2008 UK electricity generation mix; and hydrogen, considering the compressed hydrogen option from centralized natural gas reforming. This Well-to-Wheel analysis combines the Tank-to-Wheel (TTW), which accounts for the emissions and fuel consumption that result from moving the vehicle through its drive cycle, with the Well-to-Tank (WTT), which accounts for the fuel production stage. For the European certification driving cycle (NEDC), the PHEV-FC Taxi resulted in the lower WTW energy and CO2 emissions results (2.99 MJ/km and 159 g/km), followed by the HEV-FC Taxi (3.28 MJ/km and 174 g/km), and by the EV (3.21 MJ/km and 173 g/km), compared to the ICE Diesel (3.60 MJ/km and 280 g/km). For a more demanding London driving cycle a 33, 28, 54 and 154% increase in the WTW energy consumption and CO2 emissions is observed for the PHEV-FC Taxi, HEV-FC Taxi, EV and ICE Diesel respectively.
THE THERMODYNAMICS OF EXTRACTION OF SOME LANTHANIDE AND OTHER IONS BY DINONYLNAPHTHALENESULPHONIC ACID (1990)

ABSTRACT The thermodynamics of extraction of some lanthanide ions and bismuth, aluminium, calcium and zinc ions from perchloric acid into solutions of dinonylnaphthalenesulphonic acid have been studied. Extraction of the trivalent ions is dominated by the entropy of complexing. Electrostriction of large complex micelles by the complexed ion is postulated in order to account for the entropy effect. In the case of divalent ions, the enthalpy of dehydration of the ion is more important. A strategy for improving the separation factors is proposed.

The spectral structure of tes processes (1994)

TES (Transform-Expand-Sample) is a versatile class of stochastic sequences consisting of marginally uniform autoregressive schemes with modulo-1 reduction, followed by various transformations. TES modeling aims to fit a TES model to empirical records by simultaneously capturing both first-order and second-order properties of the empirical data In this paper we study the spectral properties of general TES processes and their component innovation sequences, thus generalizing the results reported in Jagerman and Melamed [9]. We derive formulas for the power spectral density function and the spectral distribution function which are suitable for efficient numerical computation, and exemplify them for TES processes with uniform and exponential marginals. The results contribute to the understanding of TES sequences as models of autocorrelated sequences, particularly in a Monte Carlo simulation context
Low thermal expansion material (LTEM) cleaning and optimization for extreme ultraviolet (EUV) blank deposition (2013)

With the insertion of extreme ultraviolet lithography (EUVL) for high volume manufacturing (HVM) expected in the next few years, it is necessary to examine the performance of low thermal expansion materials (LTEMs) and assess industry readiness of EUV substrates. Owing to the high cost of LTEM, most of the development work so far has been done on fused silica substrates. Especially in developing cleaning technology prior to multilayer deposition, fused silica substrates have been used extensively, and defect trends and champion blank data have been reported using multilayer deposition data on fused silica substrates. In this paper, the response of LTEMs to cleaning processes prior to multilayer deposition is discussed. Cleaning processes discussed in this paper are developed using fused silica substrates and applied on LTEM substrates. The defectivity and properties of LTEM to fused silica are compared. Using the dense scan feature of the substrate inspection tool capable of detecting defects down to 35 nm SiO<sub>2</sub> equivalent size and appropriate defect decoration techniques to decorate small defects on substrates to make them detectable, cleaning technologies that have the potential to meet high demands on LTEM for EUVL are developed and optimized.
Process Simulation Development of Coal Combustion in a Circulating Fluidized Bed Combustor Based on Aspen Plus (2011)

A process simulation model has been developed to simulate and predict the condition of three kinds of coal combustion in a 30 kW circulating fluidized bed combustor based on Aspen Plus with considering gas−solid hydrodynamics via Aspen Plus in-line FORTRAN codes and combustion reaction kinetics via some external FORTRAN subroutines simultaneously. The related mathematical models in the process simulation, such as a gas−solid hydrodynamics model in the CFB riser, equivalent pyrolysis model of coal, and combustion kinetics model of coal pyrolysis products, have been presented in detail. The profiles of voidage and gas pressure along the height of riser are discussed and preliminarily predicted by the developed model in this paper. It can be concluded from the results of the process simulation model that increasing gas superficial velocity can lead to a decrease of voidage in the dense region and lower acceleration region, and a slight increase of voidage in the upper acceleration region and completely fluidized region. Furthermore, increasing gas superficial velocity can also effectively increase the total pressure drop of the riser. Therefore, a larger inlet pressure is required when more primary air is introduced into the riser bottom.
Changes in Dimensionality and Fractal Scaling Suggest Soft-Assembled Dynamics in Human EEG (2017)

Humans are high-dimensional, complex systems consisting of many components that must coordinate in order to perform even the simplest of activities. Many behavioral studies, especially in the movement sciences, have advanced the notion of <i>soft-assembly</i> to describe how systems with many components coordinate to perform specific functions while also exhibiting the potential to re-structure and then perform other functions as task demands change. Consistent with this notion, within cognitive neuroscience it is increasingly accepted that the brain flexibly coordinates the networks needed to cope with changing task demands. However, evaluation of various indices of soft-assembly has so far been absent from neurophysiological research. To begin addressing this gap, we investigated task-related changes in two distinct indices of soft-assembly using the established phenomenon of EEG repetition suppression. In a repetition priming task, we assessed evidence for changes in the correlation dimension and fractal scaling exponents during stimulus-locked event-related potentials, as a function of stimulus onset and familiarity, and relative to spontaneous non-task-related activity. Consistent with predictions derived from soft-assembly, results indicated decreases in dimensionality and increases in fractal scaling exponents from resting to pre-stimulus states and following stimulus onset. However, contrary to predictions, familiarity tended to increase dimensionality estimates. Overall, the findings support the view from soft-assembly that neural dynamics should become increasingly ordered as external task demands increase, and support the broader application of soft-assembly logic in understanding human behavior and electrophysiology.
RBT-Km: K-Means clustering for Multiple Sequence Alignment (2010)

This paper presents a novel approach for solving the Multiple Sequence Alignment (MSA) problem. K-Means clustering is combined with the Rubber Band Technique (RBT) to introduce an iterative optimization algorithm, namely RBT-Km, to find the optimal alignment for a set of input protein sequences. In this technique, the MSA problem is modeled as a Rubber Band, while the solution space is modeled as plate with several poles corresponding locations in the input sequences that are most likely to be correlated and/or biologically related. K-Means clustering is then used to discriminate biologically related locations from those that may appear by chance. RBT-Km is tested with one of the well-known benchmarks in this field (BALiBASE 2.0). The results demonstrate the superiority of the proposed technique even in the case of formidable sequences.
Convective drying of lemon peel assisted by power ultrasound: influence of ultrasonic power applied (2007)

The effects associated to the introduction of acoustic energy into a medium may influence food drying processes due to the reduction of mass transfer resistance. In particular, power ultrasound may be useful for drying heat sensitive materials since it permits drying to be increased without significantly heating the material. The main aim of this work was to determine the influence of power ultrasound on lemon peel drying, by evaluating the effect of the ultrasonic power applied. Lemon peel, a by-product of lemon processing, is a source of valuable heat sensitive products. An aluminium vibrating cylinder, which is able to create a high intensity ultrasonic field in the gas medium, was used as drying chamber. The cylinder is driven at its centre by a power ultrasonic vibrator at 21.7 kHz. Convective drying kinetics of lemon peel slabs (thickness 7± 1 mm) were carried out at 40 oC and 1 m/s. Experiments were performed without ultrasound application (AIR) and also by applying different ultrasonic power levels: 10, 20, 30, 40, 50, 60, 70, 80 and 90 W. A diffusion model considering external resistance to mass transfer was used to model drying kinetics. Results showed that drying kinetics of lemon peel were affected by the application of power ultrasound. Drying rate increased as the ultrasonic power applied got higher. From the modelling, a linear relationship was found between effective diffusivity (De, m 2 /s) or mass transfer coefficient (k, kg w/m 2 /s) and the ultrasonic power applied (W). Therefore, power ultrasound increased both external and internal resistance to mass transfer, the improvement being proportional to the ultrasonic power applied.
Optimum synchronization of frames with unknown, variable lengths on gaussian channels (2005)

In this paper, we study frame synchronization based on the sync word in the general case when the frame size is unknown and possibly variable on a frame by frame basis. We assume a Gaussian channel with binary symbols and coherent decoding, where soft values are provided to the frame synchronizer. According to the hypothesis testing theory, the optimum likelihood ratio test (LRT) is derived using the Neyman-Pearson lemma. Then, the performance of the test is analytically assessed. The obtained closed form expressions allow also the derivation of the receiver operating characteristic (ROC) curves for the LRT synchronizer, showing that a remarkable gain is obtained with respect to synchronization based on a correlation metric.
SU‐FF‐T‐54: Quantification of CT Artifact Reduction of Second Generation Intracavitary Brachytherapy Applicator (2009)

Purpose: A second generation CT‐friendly applicator with movable shields has been developed for cervical carcinoma intracavitary brachytherapy (ICBT). We report on a method to quantify the reduction in CT artifact in a phantom study using this applicator. Methods and Material: A gynecological phantom was fabricated to mimic a realistic patient anatomy and to fit a standard intrauterine tandem (45 degrees) and 20‐mm diameter colpostats. Once the applicator is inserted, packing using gauze was inserted around the colpostats to reduce air cavity. The phantom with the applicator set was scanned using a CT simulator (AcQSimCT, Philips) using axial mode (2.5 mm slice, 120 kVp, 110mAs). To eliminate image artifacts, two non‐overlapping, 30° gantry tilt axial CT scanning series which met at the middle of the ovoid were used. Shields were moved before each series scan to the opposite side of the ovoid. A second CT scan without moving the shields was performed to compare artifacts. The image sets were then rigidly aligned globally using mutual information. A region of interest inside the phantom from the slice with greatest CT artifacts visually was picked for quantitative analysis. The CT number from each voxel was tallied and summary statistics were calculated. Because the images are aligned, we could determine the difference in CT numbers between corresponding voxels from both images. Results: Visually, the CT scan set with shields moved out of the way were almost completely free of artifacts. The average %diff between all the voxels was 0.6%±42% (2σ), with maximum %diff of 1,039% for voxels with the largest artifact. Conclusions: The new applicator provides artifact‐free CT imaging without compromising the shields. We found the CT protocol with tilted gantry is easy to perform using CT simulators available in the radiation oncology department.

Detection of anger with and without control for affective computing systems (2009)

Feedback from affective computing interfaces should improve awareness and self-regulation of negative emotional states, such as anger. The aim of this study was to identify cardiovascular and electroencephalography-based indicators of anger, in combination with level of control. Forty participants were split into four experimental groups: anger/no control, anger/control, neutral/no control and neutral/control. Anger (anger state vs. neutral state) was manipulated via verbal mood induction. In addition, participants were exposed to a computer-based problem-solving task where the keyboard either worked correctly (control) or malfunctioned (no control). Various psychophysiological variables (including blood pressure, cardiovascular impedance, electroencephalography and facial electromyography), in addition to self-report variables, were obtained. Statistical analyses of self-report variables indicated that manipulation of anger and control was successful. Blood pressure and electroencephalography were found to be sensitive to the anger with no control state. Implications of the study are discussed in relation to the development of biocybernetic systems to monitor different categories of anger.
Density-Dependent Predation, Habitat Variation, and the Persistence of Marine Bivalve Prey (2001)

The persistence of prey encountering intense predation varies by species, prey density, and habitat type; however, the collective impact of these factors has rarely been tested experimentally in natural marine systems. Using the thin-shelled clams Mya arenaria and Macoma balthica as prey, and the main epibenthic predator of whole adult clams, the blue crab Callinectes sapidus, we conducted a series of experiments in Chesapeake Bay tributaries that (1) links field abundance and distribution of bivalve prey species with habitat-specific mortality patterns; (2) represents the first comprehensive field test of species-specific, habitat-specific, and density-dependent mortality for subtidal, soft-bottom, deep-burrowing prey; and (3) thereby enables development of a conceptual model to be used as a heuristic tool linking predator–prey dynamics, habitat type, and evolutionary defense tactics for marine benthos. In 15 years of field monitoring, Mya was more common in sand than mud habitats, and Macoma was widely distributed and at higher densities than Mya in mud and sand. In field experiments, mortality of both Mya and Macoma was density dependent in those habitats where the clams are common. The blue crab population in the field exhibited a type III “guild functional response” on Mya in sand, and on Macoma in both mud and sand. Mortality was lower in sand than mud for Mya, and similar in mud and sand for Macoma, correlating with the high abundances of Mya in sand and Macoma in sand and mud. The persistence of large juvenile and adult bivalves when confronted with intense predation derived substantially from a low-density refuge from predation that varied in a species-specific manner with habitat type, demonstrating the species-specific importance of density and habitat to clam survival. We developed a conceptual model detailing the relative importance of behavior, morphology, habitat features, and the basic components of predator–prey interactions to the survival of bivalve molluscs. At one extreme are bivalve molluscs, such as oysters, that emphasize morphological refuges that increase the predator's handling time. At the other extreme are bivalves, such as Mya and Macoma, that reduce predator encounter rates. The model is intended to be used as a heuristic tool to develop testable hypotheses.

Hacia una propuesta para la selección de parámetros adecuados para una red inalámbrica con restricciones temporales (2014)

Las redes de área local inalámbricas juegan un rol destacado en diversos escenarios actuales, que se presentan en industrias, empresas y también a nivel doméstico (domótica). La incorporación de esta tecnología en sistemas embebidos aplicados a monitoreo, instrumentación y control es de gran importancia por la facilidad y flexibilidad que brindan para su instalación y despliegue. El estándar IEEE 802.11 define el conjunto de protocolos más comúnmente utilizado en este tipo de redes, estando sus principales funciones en las capas físicas y de con-trol de acceso al medio. Los mecanismos y procedimientos implementados en estas dos capas determinan fuertemente el rendimiento y posibilidades de aplicación de la red. El presente trabajo tiene los siguientes objetivos: (a) presentar los resultados obtenidos de una serie de ensayos realizados a fin de determinar las mejores condiciones de operación de las dos capas mencionadas, teniendo en cuenta los requerimientos típicos para una red inalámbrica de dispositivos embebidos, y (b) definir lineamientos tendientes a establecer pautas para la mejor operación de la red en función de los requerimientos impuestos. Para reali-zar algunos de estos ensayos se utilizaron módulos RCM5600W, basados en microcontrolador Rabbit 5000, con interfaz WiFi 802.11b/g.
Measurement of the Ultrafast Spectral Diffusion of the Optical Transition of Nitrogen Vacancy Centers in Nano-Size Diamond Using Correlation Interferometry (2013)

Spectral diffusion is the phenomenon of random jumps in the emission wavelength of narrow lines. This phenomenon is a major hurdle for applications of solid state quantum emitters like quantum dots, molecules, or diamond defect centers in an integrated quantum optical technology. Here, we provide further insight into the underlying processes of spectral diffusion of the zero-phonon line of single nitrogen vacancy centers in nano-size diamond by using a novel method based on photon correlation interferometry. The method works although the spectral diffusion rate is several orders of magnitude higher than the photon detection rate and thereby improves the time resolution of previous experiments with nano-size diamond by 6 orders of magnitude. We study the dependency of the spectral diffusion rate on the excitation power, temperature, and excitation wavelength under off-resonant excitation. Our results bring insight into the mechanism of spectral diffusion and suggest a strategy to increase the number of spectrally indistinguishable photons emitted by diamond nanocrystals.
