Optical Acceleration Measurement Method with Large Non-ambiguity Range and High Resolution via Synthetic Wavelength and Single Wavelength Superheterodyne Interferometry (2018)

Interferometric optomechanical accelerometers provide superior resolution, but the application is limited due to the non-ambiguity range that is always less than half of the wavelength, which corresponds to the order of mg. This paper proposes a novel acceleration measurement method based on synthetic wavelength and single wavelength superheterodyne interferometry to address this issue. Two acousto-optical modulators and several polarizers are introduced to the two-wavelength interferometry to create four beams with different frequencies and polarization states, and two ultra-narrow bandwidth filters are used to realize the single wavelength measurement simultaneously. This technique offers the possibility to expand the non-ambiguity range without compromising the high resolution. Also, the superheterodyne phase measurement and the corresponding processing algorithm are given to enable real-time measurement. A prototype is built and the preliminary experimental results are compared with the simulation results, showing good agreement. The results prove an estimated acceleration measurement resolution of around 10 μg and a non-ambiguity range of larger than 200 mg, which is more than 100 times that of the single wavelength-based optical accelerometer.
Improved algebraic methods for circle fitting (2009)

Inspired by the circle fitting algorithm “Hyper” of Al-Sharadqah and Chernov [1], which eliminates the second order “essential bias” that excludes terms of O(σ2/N2), we extend their analysis and show that by a small modification the second order bias can be eliminated completely. By numerical experiments, we show that this results in better performance when the number N of points is small and the noise is large.
Associations between γ-glutamyl transferase, metabolic abnormalities and inflammation in healthy subjects from a population-based cohort: A possible implication for oxidative stress (2005)

GGT, an easy, universally standardized and available measurement, could represent an early marker of sub-clinical inflammation and oxidative stress in otherwise healthy individuals. Prospective studies are needed to establish if GGT could predict future diabetes in these subjects.
Catalytic dehydrogenation condensation of silyl hydrides and amines: thermal decomposition of silazanes and polysilazanes (1988)

s hydrogen to produce propene. It is difficult to estimate how much of each mechanism is contributing to the overall decomposition, since trapping of the allyl radical is not an efficient process. Likewise most likely decomposes by the two mechanisms outlined above. This conclusion is based on similar 99 SFR ^ C3H6 + 101 E a = 54.5 ± 0.5 Kcal/mol log A = 12.9 ±0.1 evidence.

New Developments in the Analysis of Scale Inhibitors (2010)

Summary Scale inhibitors (SIs) are used to control oilfield scale formation, and the ability to analyze these species is very important such that SI concentrations as low as 0.5-ppm active need to be measured accurately. If phosphorus is present in the SI molecule, then inductively-coupled-plasma (ICP) -based methods may be used for analysis. However, the oil industry's increasing requirement to be environmentally friendly means that polymeric "green" SIs are now being used more, which raises issues concerning detection techniques (i.e., ICP vs. wet-chemical techniques). ICP detection for SIs is generally easier, but if it cannot be used, then at least time-saving improvements to wet-chemical techniques are extremely beneficial. In this paper, analytical approaches are described that have been used recently to improve chemical SI assay, especially at low near-threshold levels (a few ppm active of SI). Progress is reported in five areas of SI analysis: Assay of sulfonated copolymer (VS-Co) was not possible by straightforward analysis without extensive dialysis and sample preparation. However, calibrations and repeats of accuracy similar to that of the C18 were found for VS-Co using amino-propyl (NH2) cartridges and the Hyamine method.The Oasis® 2×4 method has been applied to SI analysis, and this is able to assay all types of polymeric SIs in principle. This method has been used to detect a VS-Co SI in a wide variety of different brine salinities from distilled water (DW) to high-salinity formation waters (FW) (e.g., a Heron-type FW). Although achievable under these different conditions, there was a significant decrease in the absorbance signals recorded with increasing salinity that was not significantly improved by a higher-capacity sorbent cartridge.Various elements have been assayed in the oil phase using the ICP method. Calibrations and accurate repeats within 5 to 10% error were achieved. After solving compatibility issues, the concentration of an oil-tolerant SI was determined successfully using calibrations and accurate repeats over a range of 0 to 10 ppm and 0 to 2,500 ppm active SI.A matrix-matching Hyamine technique has been developed that allows any chloride-ion effects on the chelating process between the Hyamine and SI to be negated, allowing accurate analysis of low-polymeric SI concentrations.ICP and wet-chemical techniques have been able to accurately detect a P-tagged (phosphorus-tagged) copolymer-type SI. The ability to apply two independent analytical methods to a given species offers some important advantages when more than one SI is deployed in a field system. In this work, excellent correlation is observed between the wet-chemical and ICP assay methods for this P-tagged SI. This study updates and adds to the set of analytical methods and procedures reported for SI analysis almost 20 years ago (Graham et al. 1993, 1995a, 1995b, 1996; Sorbie et al. 1992) and are described in our Flow Assurance and Scale Team (FAST) laboratory procedures manual (Sorbie and Boak 2006).
The Role of Inventory in Delivery-Time Competition (1992)

The paper operationalizes the notion of shortage cost by considering the behavior of customers and competing firms and examines the role of inventory in response time competition. We start with a single-firm production control model in which customers are characterized by their preferences of price, quality and delivery time. The optimal production/inventory policy and the optimal choice between make-to-order and make-to-stock operations are determined in simple “newsboy”-like formulas. The basic model is then extended to an n-firm market game in which firms compete for orders from the aspect of early delivery. One could think of this setting as an oligopoly racing market. The analysis shows that competition can breed a demand for produce-to-stock, just as other economic phenomena such as economies of scale, uncertainty, or seasonality can induce make-to-stock, and that delivery-time competition increases the buyer's welfare while decreasing the producer's welfare.
The University and the Creative Arts (1962)

The following discussion on the university and the creative arts was prepared for an audience of graduate deans under conditions noted in the first two paragraphs of the text. It is admittedly one-sided: I had suggested to the Association of Graduate Schools that a professor of drama, music, or the visual arts be given a hearing on the same program. The AGS urged me to lake the role of prosecutor, with the promise that its Committee on Policies would keep the subject on its agenda and afford opportunities for rebuttal. I am confident that readers of the ART JOURNAL will lake up the debate and thus help to clarify many of the issues involved in university training in the arts—W.M.L.
Remote Sensing of Landslides—A Review (2018)

Triggered by earthquakes, rainfall, or anthropogenic activities, landslides represent widespread and problematic geohazards worldwide. In recent years, multiple remote sensing techniques, including synthetic aperture radar, optical, and light detection and ranging measurements from spaceborne, airborne, and ground-based platforms, have been widely applied for the analysis of landslide processes. Current techniques include landslide detection, inventory mapping, surface deformation monitoring, trigger factor analysis and mechanism inversion. In addition, landslide susceptibility modelling, hazard assessment, and risk evaluation can be further analyzed using a synergic fusion of multiple remote sensing data and other factors affecting landslides. We summarize the 19 articles collected in this special issue of Remote Sensing of Landslide, in the terms of data, methods and applications used in the papers.
Mechanical and Biological Interactions of Implants with the Brain and Their Impact on Implant Design (2016)

Neural prostheses have already a long history and yet the cochlear implant remains the only success story about a longterm sensory function restoration. On the other hand, neural implants for deep brain stimulation are gaining acceptance for variety of disorders including Parkinsons disease and obsessive-compulsive disorder. It is anticipated that the progress in the field has been hampered by a combination of technological and biological factors, such as the limited understanding of the longterm behavior of implants, unreliability of devices, biocompatibility of the implants among others. While the field's understanding of the cell biology of interactions at the biotic-abiotic interface has improved, relatively little attention has been paid on the mechanical factors (stress, strain), and hence on the geometry that can modulate it. This focused review summarizes the recent progress in the understanding of the mechanisms of mechanical interaction between the implants and the brain. The review gives an overview of the factors by which the implants interact acutely and chronically with the tissue: blood-brain barrier (BBB) breach, vascular damage, micromotions, diffusion etc. We propose some design constraints to be considered in future studies. Aspects of the chronic cell-implant interaction will be discussed in view of the chronic local inflammation and the ways of modulating it.
Quality and Storage of `Granny Smith' and `Greenspur' Apples on Seedling, M.26, and MM.111 Rootstock (1991)

Influences of rootstock on the quality of `Granny Smith' and `Greenspur' apples (Malus domestica Borkh.) were evaluated over an extended harvest period and after cold storage. Apples from trees on M.26 rootstock had the higher firmness, soluble solids concentration (SSC), and Ca content, but poorer external color (red blush) and a higher percentage of solar injury than fruit from trees on seedling or MM.111 rootstock. External greenness was best on apples from MM.111 rootstock. `Granny Smith' apples had higher firmness, soluble solids, acids, and carbohydrate contents, and less scald but poorer external greenness than `Green spur' apples. `Granny Smith' or `Greenspur' apples from M.26 rootstock appeared to mature earlier than those on MM.111.

Coalesced CAP: An Improved Technique for Frequency Assignment in Cellular Networks (2006)

This paper presents an elegant technique for solving the channel assignment problem (CAP) for second generation (2G) cellular mobile networks, where channel allocation is made on a quasi-fixed basis and all sessions are connection oriented. It first maps a given CAP P to a modified coalesced CAP P' on a smaller subset of cells of the network, which appreciably reduces the search space. This helps to solve the problem P' by applying approximate algorithms very efficiently, reducing the computing time drastically. This solution to P' is then used to solve the original problem P by using a modified version of the forced assignment with rearrangement (FAR) operation reported by Tcha et al. (IEEE Trans. Veh. Technol., vol. 49, p. 390, 2000). The proposed technique has been tested on well-known benchmark problems. It has produced optimal solutions for all cases with an improved computation time. For instance, it needs only around 10 and 20 s (on an unloaded DEC Alpha station 200 4/233) to get an optimal assignment for the two most difficult benchmark problems 2 and 6, respectively, with zero call blocking, in contrast to around 60 and 72 s (on an unloaded Sun Ultra 60 workstation) reported by Ghosh et al. Moreover, as a by-product of this approach, there remain, in general, many unused or redundant channels that may be used for accommodating small perturbations in demands dynamically.
Area- and Power-Efficient Architecture for High-Throughput Implementation of Lifting 2-D DWT (2012)

We have suggested a new data-access scheme for the computation of lifting two-dimensional (2-D) discrete wavelet transform (DWT) without using data transposition. We have derived a linear systolic array directly from the dependence graph (DG) and a 2-D systolic array from a suitably segmented DG for parallel and pipeline implementation of 1-D DWT. These two systolic arrays are used as building blocks to derive the proposed transposition-free structure for lifting 2-D DWT. The proposed structure requires only a small on-chip memory of (4N + 8P) words and processes a block of P samples in every cycle, where N is the image width. Moreover, it has small output latency of nine cycles and does not require control signals which are commonly used in most of the existing DWT structures. Compared with the best of the existing high-throughput structures, the proposed structure requires the same arithmetic resources but involves 1.5N less on-chip memory and offers the same throughput rate. ASIC synthesis result shows that the proposed structure for block size 8 and image size 512 512 involves 28% less area, 35% less area-delay product, and 27% less energy per image than the best of the corresponding existing structures. Apart from that, the proposed structure is regular and modular; and it can be easily configured for different block sizes.
A mutation in the large subunit ribosomal RNA gene of Tetrahymena confers anisomycin resistance and cold sensitivity. (1991)

Anisomycin, an antibiotic that specifically inhibits the peptidyl transfer function of eukaryotic ribosomes, has been used to select resistant mutants in Tetrahymena thermophila. A mutation conferring anisomycin resistance (an-r) has been localized to a 1.2-kb fragment of the large subunit ribosomal RNA (rRNA) gene by transformation via microinjection. A single base pair change was detected within this region. Nine independently isolated an-r mutants had the same base pair change. T. thermophila strains that are homozygous for this mutation are cold sensitive, unable to mate and grossly abnormal in cell morphology.
Healing of tooth extraction sockets in the streptozotocin diabetic rat model: Induction of cartilage by BMP-6 (2010)

Cartilage does not form in the tooth extraction socket of the normal rat. The aim of the study was to determine if adding BMP-6 to the extraction socket would cause chondrogenic differentiation in the diabetic rat. A group of 8-week-old rats were injected intraperitoneally with a diabetogenic agent, streptozotocin, and a control group received citrate buffer only. Three weeks later, the maxillary molar teeth were extracted and either BMP-6 or saline applied to the extraction sockets. Rats from each group were killed on days 3, 5, 7, and 9 after tooth extraction. In the diabetic rats treated with BMP-6, there was a cellular subperiosteal reaction at day 3 in the extra-alveolar tissues, which by day 7 had formed a large mass of cartilage. Cartilage was induced in the subperiosteal region of the socket extra-alveolar bone following the application of BMP-6 in the diabetic rat.
Simulation and Optimization of an Adjustable Inlet Guide Vane for Industrial Turbo Compressors (2008)

To investigate the kinematics and dynamics of an adjustable inlet guide vane mechanism (IGV) for industrial turbo compressors, an IGV was modeled as a multibody system (MBS) consisting of elastic interconnections and rigid bodies. Besides investigating the IGV kinematics, its vibrations and structural strength were also verified numerically. The kinematic analyses enabled the design to be optimized in terms of undesirable collisions between the interconnected bodies. The pressure exerted on the guide vanes, which is calculated by CFD simulations, forms a set of forces and torques for each blade. These sets were created for two different performance maps, referred to in the following as Gas I and Gas II. Calculating the desired drive torque, joint reaction forces and the driving ring’s displacements were the essential inputs for the dynamic multibody analyses performed. These investigations showed that the desired torque to drive the mechanism is governed by the sliding element’s friction forces. The gas forces were able to raise the torque by roughly 6% and 32.6% for Gas I and II, respectively. Due to uncertainties in the determination of the friction coefficients, the highest expected values were taken into account for selecting an accurate actuator for the IGV. The strength and vibration analyses were carried out using the Finite Element (FE) Method. All computed critical natural frequencies of the IGV can be empirically considered to be highly damped resonances in the actual system due to joint friction effects. Reaction forces determined by the dynamic multibody analyses were transferred as loads to the FE model. In most cases, the joint reaction forces have been so low that no further investigations were necessary. Hence, verification of strength was carried out using a contact FE analysis for the highest loading condition between the assembly and the pin, which transfers the entire drive force from a lever into the driving ring.
Control over the Wettability of an Aligned Carbon Nanotube Film (2003)

Three-dimensional anisotropic aligned carbon nanotube microstructures were constructed by the chemical vapor deposition method on silicon templates with well-defined structure. It brought about new properties of wettability. Superhydrophobic (contact angle > 150 degrees ) and very hydrophilic (contact angle < 30 degrees ) properties can both be achieved by a simple change of structural parameter.
Chronic pancreatitis (1994)

The clinical manifestations of chronic pancreatitis may be quite varied, ranging from a debilitating disease associated with excruciating pain and pancreatic exocrine and endocrine insufficiencies, to a relatively indolent course with intermittent episodes of abdominal discomfort. In the Western world, the majority of cases are due to chronic and excessive alcohol ingestion and to idiopathic forms of the disease. Additional causes may include trauma, hypercalcemia, cholelithiasis, pancreatic duct obstruction, hypertriglyceridemia, cystic fibrosis, hereditary factors, and congenital abnormalities. In some parts of the world, poorly understood nutritional dysfunctions contribute to a form of chronic pancreatitis in which pancreatic calcifications predominate. This review focuses on the natural history of chronic pancreatitis, an update on treatment modalities, new insights on the molecular alterations that occur in this condition, and the potential relationship between chronic pancreatitis and pancreatic cancer.
Laser machining characteristics in multi-layer thin film structures. (1991)

Laser machining of multi-layer thin film is promissing to become an important processing in fabrications of electronic circuits. The various factors having influence on the characteristics of multi-layer thin film machining with a laser are evaluated theoretically and experimentally. The three dimensional heat diffusion equations including laser light absorption in multi-layer thin film structure are solved numerically to give the time evolution of temperature. Experiments were performed on amorphous Si (a-Si) multi-layer thin film structure of various thickness on transparent conductive oxide(TCO)/glass substrate to verify numerical results. The samples were irradiated with a Q-switched Nd : YAG laser at λ= 1. 06 μm and at λ =0.53, μm. The experimental results on the dependence of laser wavelength, laser pulse duration and laser irradiated energy on machining characteristics are in good agreement with the calculated results.
Improving Stability of Li-Ion Batteries by Means of Transition Metal Ions Trapping Separators (2016)

Transition metal ions dissolution from positive electrodes initiates a well-known degradation mechanism in Li-ion cells, which limits their operational life. Preventing its consequences should be considered as a breakthrough in the field. We show herein that trapping Mn ions by ion-chelating polymers placed in the inter-electrode space of cells with lithium manganate spinel and Li or graphite electrodes, and greatly improves their high temperature cycling performance. Mn cations trapping separators were fabricated in-house using a commercial resin consisting of iminodiacetic acid disodium salt functional groups on a styrene divinylbenzene polymeric matrix, either by their inclusion into a separator through a phase-inversion method or by coating onto a plain commercial separator. We determined and compared the surface and cross-section morphologies, electrolyte-uptake, porosity, ionic-conductivity, and electrochemical-stability of these separators with those of a baseline separator. LMO-Li cells containing phase-inversion separators had ∼15x less Mn on the Li-electrode than cells with the baseline separator, after 100 cycles at 55°C. LMO-graphite cells with phase-inversion separators had ∼6x less Mn on the graphite-electrode, after 100 cycles at 55°C than cells with the baseline-separator. Capacity losses after cycling at 55°C were 30% and 55%, respectively, for the cells with phase-inversion and baseline separators.
Y Chromosome SNP Analysis Using the Single-Base Extension: A Hierarchical Multiplex Design (2004)

Single nucleotide polymorphisms (SNPs) are the most frequent polymorphisms described in the human genome, and their analysis is becoming an extensive routine in molecular biology, not only in the forensic field, but also in population and clinical genetics. In particular, SNPs located on the Y chromosome have a specific utility as forensic tools, and based on this fact, we have designed a strategy that allows us to identify the most frequent haplogroups in European populations. We selected 29 markers among the 245 binary polymorphisms described in the Y-Chromosome Consortium tree. The whole set was grouped into four multiplexes in a hierarchical way, allowing us to determine the final haplogroup using only one or two multiplexes. In this way, we only type in the best-case nine SNPs, and in the worst possible combination 17 SNPs, to define the haplogroup. The selected strategy to type the SNPs was a single-base extension method using the SNaPshot multiplex kit from Applied Biosystems, and detailed practical procedures are described here. With this hierarchical strategy adapted for European populations the massive typing of SNPs was avoided, and therefore the time and money involved in the study was also reduced.
