Structure, diffusion and rheology of Brownian suspensions by Stokesian Dynamics simulation (2000)

The non-equilibrium behaviour of concentrated colloidal dispersions is studied using Stokesian Dynamics, a molecular-dynamics-like simulation technique for analysing suspensions of particles immersed in a Newtonian fluid. The simulations are of a monodisperse suspension of Brownian hard spheres in simple shear flow as a function of the Péclet number, Pe , which measures the relative importance of hydrodynamic and Brownian forces, over a range of volume fraction 0.316 [les ] ϕ [les ] 0.49. For Pe < 10, Brownian motion dominates the behaviour, the suspension remains well-dispersed, and the viscosity shear thins. The first normal stress difference is positive and the second negative. At higher Pe , hydrodynamics dominate resulting in an increase in the long-time self-diffusivity and the viscosity. The first normal stress difference changes sign when hydrodynamics dominate. Simulation results are shown to agree well with both theory and experiment.
Photo-Definable Nanocomposite for Wafer Level Packaging (2005)

A novel nanocomposite photo-definable material which can act both as a photoresist and a stress redistribution layer applied on the wafer level was synthesized and studied. In the experiments, the 20nm silica fillers are modified by silane coupling agent through the hydrolysis and condensation reaction and then incorporated into the epoxy matrix. A photo-sensitive initiator is added into the formulation which can release the cations after UV exposure and initiate the epoxy crosslinking reaction. The photo-crosslinking reaction of the epoxy makes it a negative tone photoresist. The curing reaction of the nanocomposites is monitored by the differential scanning calorimeter (DSC) with photocalorimetric accessory (PCA). The thermal mechanical properties of photo-cured nanocomposites thin film are measured. The addition of nano-size silica fillers not only reduces the thermal expansion and improves the mechanical property of the epoxy, but also has less influence on the optical property of the epoxy, which insures the occurrence of the photo reaction in epoxy.
Verapamil-Induced Hyperprolactememia Complicated by a Pituitary Incidentaloma (1995)

The failure to identify the hyperprolactinemic effect of verapamil may have resulted in performing unnecessary radiologic procedures in this patient. This case highlights the importance of obtaining a medication history in patients with hyperprolactinemia.
Interactive analysis of hierarchical image segmentation (2002)

At IGARSS'98 the authors described segmentation approach based on region growing and spectral clustering. This approach produces a hierarchical set of image segmentations in which the regions may consist of non-spatially connected objects. The authors describe a "Region Labeling Tool" that can be used produce customized image labelings. They demonstrate the Region Labeling Tool in a land cover analysis of a Landsat TM data set over the Baltimore, MD and Washington, DC area. They have seen that a key benefit of using the Region Labeling Tool with hierarchical segmentations is that a much fuller utilization of the spectral and spatial information content of imagery is obtained than possible with most other analysis techniques.
Two-color infrared full-Stokes imaging polarimeter development (1999)

Infrared polarization imaging shows great potential to improve system performance in a variety of tactical applications. Previous IR polarization imaging has highlighted the possible utility of polarization as a way to easily separate manmade objects from natural backgrounds. If the polarization signatures are indeed robust across a wide variety of tactical imaging conditions, polarization stands to significantly improve our ability to automatically detect and cue targets. Man-in-the-loop applications stand to benefit as well: in search scenarios both the time to detect and false alarm rate could be substantially reduced. The possible benefits of polarization imaging require a more complete study of target and background phenomenology before polarization imaging can seriously be considered as a candidate tactical sensor. In order to accurately quantify the target and background signatures and to address questions such as optimal waveband and choice of Stokes vector components sensed, the U.S. Army Night Vision and Electronic Sensors Directorate (NVESD) is developing a breadboard infrared (IR) polarization imaging capability. This paper covers the sensor design, choice of polarization elements, problems with their fabrication, alignment, calibration and use. Different polarization sensing approaches are compared and their tactical utility is addressed. Sample imagery is then presented.
A Framework of Constraint Preserving Update Schemes for Optimization on Stiefel Manifold (2013)

This paper considers optimization problems on the Stiefel manifold $X^{\mathsf{T}}X=I_p$, where $X\in \mathbb{R}^{n \times p}$ is the variable and $I_p$ is the $p$-by-$p$ identity matrix. A framework of constraint preserving update schemes is proposed by decomposing each feasible point into the range space of $X$ and the null space of $X^{\mathsf{T}}$. While this general framework can unify many existing schemes, a new update scheme with low complexity cost is also discovered. Then we study a feasible Barzilai-Borwein-like method under the new update scheme. The global convergence of the method is established with an adaptive nonmonotone line search. The numerical tests on the nearest low-rank correlation matrix problem, the Kohn-Sham total energy minimization and a specific problem from statistics demonstrate the efficiency of the new method. In particular, the new method performs remarkably well for the nearest low-rank correlation matrix problem in terms of speed and solution quality and is considerably competitive with the widely used SCF iteration for the Kohn-Sham total energy minimization.
Proactive Management of Water Quality in Aquifer Storage Transfer and Recovery (2016)

This paper reports the status of an ongoing effort to ensure the quality of water produced at an Aquifer Storage Transfer and Recovery (ASTR) site in South Korea. ASTR is one of the managed aquifer recharge techniques in which water is intentionally recharged to suitable aquifers for subsequent recovery. Surface water injected to an aquifer is converted into water of drinkable quality by natural process. In an ASTR project being developed in the densely populated delta area of the Nakdong River basin, a new framework is being implemented in which water safety is addressed through the analysis and control of biological, chemical, and physical hazards from intake, pretreatment, injection and recovery, to distribution and consumption of water. The task is done by the incorporation of Hazard Analysis and Critical Control Point (HACCP) to the ASTR process. Originated from the food industry, HACCP identifies, evaluates, and controls hazards to ensure the safety of the product. Principles of HACCP were applied to the ASTR water production system. Hazard analysis revealed that most hazardous events were due to the chemicals transported in the basin. Risk assessment was conducted to identify the sources of chemicals which pose a potential threat to the water quality of the ASTR site. Such information will be valuable for the proactive management of chemicals at the basin scale. Critical control points (CCP) were determined by the decision tree method, and critical limits for water quality parameters at CCPs were established subsequently.\n

Evaluation of the Morphology and Biocompatibility of Natural Silk Fibers/Agar Blend Scaffolds for Tissue Regeneration (2018)

This study was aimed to develop a tissue engineering scaffold by incorporation of Bombyx mori silk fiber (BMSF) and agar. This promised the improvement in enhancing their advantageous properties as well as limiting their defects without occurring chemical reactions or crosslink formation. The morphology and chemical structure of scaffolds were observed using scanning electron microscope (SEM) observation and Fourier transform infrared (FT-IR) spectra. The SEM results show that scaffolds containing BMSF have microporous structures, which are suitable for cell adhesion. Agar scaffolds, by contrast, had much more flat morphology. FT-IR spectra confirm that no modifications to BMSF happened in scaffolds, which indicates that there was no chemical reaction or crosslink formation between silk and agar in this process. Furthermore, the biocompatibility of scaffolds was performed in the mouse’s subcutaneous part of the dorsal region for 15 days, followed by Haematoxylin and Eosin (H&E) staining. H&E staining results demonstrate that scaffolds had good biocompatibility and there was no sign of the body rejection in all of samples. The results from animal study show that SA scaffolds have the most stable structure for cell adhesion compared with those single materials.
Kinetics of solute leachate from imbibing Caesalpinia echinata Lam. (Brazilwood) seeds (2014)

The electrical conductivity of leachates from imbibing seeds has been used as a vigor test for several species. The adaptation of this methodology to different species requires knowledge on the leaching kinetics of electrolytes. For Brazilwood seeds, the classic method was not satisfactory and rapid tests are essential because they have low storage capacity at room temperature. Leaching kinetics during seed imbibition is a function of physiological quality, presence or absence of seed coat, imbibing temperature and the initial moisture content of seed. In this study, the electrolyte leaching rate of six different categories of seeds, from two regions, was evaluated in seeds with and without seed coat and incubated with different moisture contents and at different temperatures. The results showed that the electrolyte leaching rate in Brazilwood seeds is independent of the physiological quality, the presence or absence of seed coat and imbibition temperature, but these factors changed the total amount of electrolytes leached. The leaching rate increased in the first few minutes of imbibition, suggesting that the adjustment of the methodology must consider the reduction in imbibition time, reduction in temperature, use of a controlled and slower pre-imbibition, and replacement of the imbibition solution after the first few minutes.

Cognitive Deficit Caused by Regional Depletion of Dopamine in Prefrontal Cortex of Rhesus Monkey (1979)

Depletion of dopamine in a circumscribed area of association cortex in rhesus monkeys produces an impairment in spatial delayed alternation performance nearly as severe as that caused by surgical ablation of the same area. This behavioral deficit can be pharmacologically reversed with dopamine agonists such as L-dopa and apomorphine. These data provide direct evidence that dopamine plays an important role in a specific cortical function.
Development and Control of an Autonomously Obstacle-Navigation Inspection Robot for Extra-High Voltage Power Transmission Lines (2006)

This paper presents a mobile robot suspended on power transmission lines based on a novel movement mechanism with two manipulators and a body. After the inspection robot configuration is described, the kinematics of the inspection robot and the process of obstacle-navigation are analyzed in details. In order to achieve autonomously control the task-oriented integrated control architecture is adopted, and the architecture is a multi-agent system coordinate and organized by distribute blackboard. To achieve auto obstacle-navigation control, camera-in-hand system is adopted to realize power transmission line pose locating. With the power line locating algorithm, a dynamic position based look-and-move control structure is implemented to achieve line-grasping control. Experiments result shows that the robot can realize auto obstacle-navigation control and proves the valid of the control method

Operating Schedule of Battery Energy Storage System in a Time-of-Use Rate Industrial User With Wind Turbine Generators: A Multipass Iteration Particle Swarm Optimization Approach (2007)

This paper presents a new algorithm for the solution of nonlinear optimal scheduling problems. This algorithm is called ldquomultipass iteration particle swarm optimizationrdquo (MIPSO). A new index called ldquoiteration bestrdquo is incorporated into ldquoparticle swarm optimizationrdquo (PSO) to improve solution quality. The concept of multipass dynamic programming is applied to further modify the PSO to improve computation efficiency. The MIPSO algorithm is used to solve the optimal operating schedule of a battery energy storage system (BESS) for an industrial time-of-use (TOU) rate user with wind turbine generators (WTGs). The effects of wind speed uncertainty and load are considered in this paper, and the resulting optimal operating schedule of the BESS reaches the minimum electricity charge of TOU rates users with WTGs. The feasibility of the new algorithm is demonstrated by a numerical example, and MIPSO solution quality and computation efficiency are compared to those of other algorithms.
PREPARATION OF URANIUM DIOXIDE FOR USE IN CERAMIC FUELS. PART I. BATCH PRECIPITATION OF AMMONIUM DIURANATE (1958)

BS>Experiments were made to determine a suitable method for making ammonium diuranate (ADu) which could be reduced in hydrogen to give a readily sinterable U0/sub 2/. The factors in precipitation with ammonium hydroxide which tended to give a readily sinterable powder were high ammonium hydroxide concentration, high temperature, high pH, and relatively fast addition of the hydroxide to the uranyl nitrate solution. Precipitation with gaseous ammonia gave a readily sinterable material under almost all conditions, but the UO/sub 2/ produced had to be sintered at a slower rate to prevent breaking of the pellets during sintering. Simple tapdensity and Blaine air-permeability tests made on either the ammonium diuranate or the uranium dioxide gave an indication of the sinterability of the material. Precipitation conditions are specified for production of ammonium diuranate powder, which when reduced, pressed and sintered, will give a sintered density above 10.4 g/cm/sup 3/ (95% of theoretical).

Bipartite Matching with Linear Edge Weights (2016)

Consider a complete weighted bipartite graph G in which each left vertex u has two real numbers intercept and slope, each right vertex v has a real number quality, and the weight of any edge (u, v) is defined as the intercept of u plus the slope of u times the quality of v. Let m (resp., n) denote the number of left (resp., right) vertices, and assume that m geq n. We develop a fast algorithm for computing a maximum weight matching (MWM) of such a graph. Our algorithm begins by computing an MWM of the subgraph induced by the n right vertices and an arbitrary subset of n left vertices; this step is straightforward to perform in O(n log n) time. The remaining m - n left vertices are then inserted into the graph one at a time, in arbitrary order. As each left vertex is inserted, the MWM is updated. It is relatively straightforward to process each such insertion in O(n) time; our main technical contribution is to improve this time bound to O(sqrt{n} log^2 n). This result has an application related to unit-demand auctions. It is well known that the VCG mechanism yields a suitable solution (allocation and prices) for any unit-demand auction. The graph G may be viewed as encoding a special kind of unit-demand auction in which each left vertex u represents a unit-demand bid, each right vertex v represents an item, and the weight of an edge (u, v) represents the offer of bid u on item v. In this context, our fast insertion algorithm immediately provides an O(sqrt{n} log^2 n)-time algorithm for updating a VCG allocation when a new bid is received. We show how to generalize the insertion algorithm to update (an efficient representation of) the VCG prices within the same time bound.
An Anthracene‐Appended β‐Cyclodextrin‐Based Dyad: Study of Self‐Assembly and Photoinduced Electron‐Transfer Processes (2007)

The self-assembly of a beta-cyclodextrin (beta-CD)-based supramolecular dyad is reported, in which the donor anthracene moiety is covalently linked to the smaller rim of the beta-CD and the acceptor pyromellitic diimide (PMDI) is encapsulated within the beta-CD cavity. Encapsulation of the PMDI into the beta-CD cavity was studied by a variety of techniques, which suggested that PMDI is encapsulated so as to position the aromatic part at the centre of the cavity with the 2-propyl end at the narrower rim among the overhanging primary OH groups and the N-ethylpyridinium end situated at the wider rim exposed to water. Photoinduced electron transfer (PET) in the system was studied by fluorescence quenching and laser flash photolysis techniques. At [PMDI]<10(-4) M, the equilibrium is in favour of the free molecules, and under these conditions fluorescence quenching is negligible and diffusion-mediated electron transfer involving the triplet excited state of anthracene predominates. At higher concentrations of PMDI, the equilibrium is largely in favour of the supramolecular dyad and intra-ensemble PET processes predominate. The experimentally determined electron-transfer rate constant agrees very well with that calculated by using the Marcus equation. It was observed that a fraction of the ion pairs survived for more than 200 micros.
Optimal design of IIR frequency-response-masking filters using second-order cone programming (2003)

The frequency-response-masking (FRM) technique proposed by Lim (1986) has proven effectiveness for the design of very sharp digital filters with reduced implementation complexity compared to other options. In this paper, we propose a constrained optimization method for the design of basic and multistage FRM filters where the prototype filters are of infinite-impulse response (IIR) with prescribed pole radius. The design is accomplished through a sequence of linear updates for the design variables with each update carried out using second-order cone programming. Computer simulations have demonstrated that the class of IIR FRM filters investigated in the paper offers an attractive alternative to its finite-impulse response counterpart in terms of filter performance, system delay, and realization complexity.
SOI: opportunities and challenges for sub-0.25 mu m VLSI (2003)

It is argued that, as VLSI minimum feature size is reduced down to the 0.25- mu m regime and below, utilization of silicon-on-insulator (SOI) as the substrate offers a number of key advantages over bulk silicon. Scaling of the room-temperature CMOS is rapidly approaching its limits. SOI devices in the 0.25- mu m regime and below show significant performance improvements compared with bulk CMOS. This suggests that SOI substrates could provide the highest performance room-temperature CMOS, provided a number of outstanding problems are solved. SOI also has a clear advantage over bulk for low-temperature (77 K) operation at a reduced voltage. In bipolar technology, SOI allows realization of devices with no parasitic junction capacitance, sub-0.25 mu m emitter widths, easy isolation, and CMOS-like density. Ease of isolation on SOI allows easy integration of MOS and bipolar devices.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
