Determination of Displacements from Holograms Using Simply Applied Methods that are Comparable to Speckle Techniques. (1978)

A system of equations is developed which relates the general displacement field from usual and image-plane double exposure holograms of objects illuminated by collimated or point light sources. By defining a coordinate system in the direction of the holographic plate and requiring that the object be several plate diameters from the plate, certain simplifications in the system of equations can be made to decouple the displacement components. As a result, the in-plane components can be independently determined from the apparent fringe shift observed from the holographic plate. The out-of-plane component can then be solved from a linear equation using the in-plane components. All three components of displacement can be simultaneously determined from a single film plate, regardless of the proportion of in- to out-of-plane components. The method is validated by comparisons with speckle results and theoretical analyses. (Author)
Fractal Energy Spectrum of a Polariton Gas in a Fibonacci Quasiperiodic Potential (2014)

We report on the study of a polariton gas confined in a quasiperiodic one-dimensional cavity, described by a Fibonacci sequence. Imaging the polariton modes both in real and reciprocal space, we observe features characteristic of their fractal energy spectrum such as the opening of minigaps obeying the gap labeling theorem and log-periodic oscillations of the integrated density of states. These observations are accurately reproduced solving an effective 1D Schrödinger equation, illustrating the potential of cavity polaritons as a quantum simulator in complex topological geometries.
Asymmetrical Motor Behavior in Animal Models of Human Diseases (1996)

This chapter will address primarily the behavioral characterization of lesion effects in the central nervous system (CNS). Animal models of Parkinson’s (PD) and Huntington’s disease (HD) will be discussed with emphasis on the novel “elevated body swing test” (EBST) in characterizing the behavioral deficits following unilateral CNS lesions. Advantages of the drug-free EBST paradigm over the conventional drug-induced rotational test in unilaterally lesioned rats will be presented. Because basal ganglia dysfunction underlies the pathophysiology of these two clincial disorders, it is appropriate to begin with an introduction of the basal ganglia.

Perception of missing fundamentals in zebra finches and Bengalese finches. (2000)

Perception of missing fundamental is widespread in vertebrate animals but seldom it is discussed with the relationship with vocal signals used by the animals.We tested the perception of missing fundamentals in two species of closely related finches with widely different vocal signals.Zebra finches and Bengalese finches were trained, in a Go-Nogo operant task, to discriminate between two harmonic complexes that were constructed by adding integer multiples of a 400Hz or a 652Hz.Both stimuli produced the perception of missing fundamentals to human listeners.After the birds learned the task, 4 sine waves, the fundamental frequency of each of the training stimuli and the geometric average frequency of each, were presented as probe stimuli along with the original training stimuli.Both species responded more to the missing fundamental of the Go stimuli than to that of Nogo stimuli.However, both species of birds responded more to the geometric averages of the stimuli than to the missing fundamentals.Thus, in these birds, the perception of the spectral pitch is dominant over the perception of the periodicity pitch and this tendency was not dependent upon the types of vocalizations each species produced.
Polarization holography for optical data storage (Conference Presentation) (2018)

The conventional holography is based on recording of intensity of holographic fringes. An alternative polarization stage recording approach is proposed to increasing storage capacity of holographic memory.
Laboratory Study on Precipitation of Calcium Sulphate in Berea Sandstone Cores (2005)

Abstract Scale deposition is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Mixing of these waters could cause precipitation of CaSO4, BaSO4 and/or SrSO4. To generate reaction kinetics data, the rate of calcium sulphate deposition in porous rock was measured while flooding Berea core samples of uniform properties with supersaturated brine. The brine was formulated by mixing a Ca+2-rich solution with a SO4−2-rich solution at the core inlet. The rate of CaSO4 scale formation was estimated by monitoring the core effluent's Ca+2 ion concentration. Several parameters were varied including temperature, pressure, degree of brine super-saturation, and flooding velocity. The results indicated increased rate of CaSO4 precipitation at higher temperatures, higher flood velocities, and greater brine super-saturation, whereas pressure had a slight effect on CaSO4 deposition. The results were utilized to build a general reaction rate equation to predict CaSO4 deposition in Berea sandstone for a given temperature, brine super-saturation, and flooding velocity.
The Temperature Field Digitization of Radiation Images in Blast Furnace Raceway (2006)

This article applies digital image processing techniques to the research for the algorithm of peep-temperature-field of flame image. Embarking on the factors which produce errors, the traditional bicolorimetric temperature measurement method is obtained proofreading. Then this algorithm is applied to the research on establishment of the temperature fields for gas combustion flame image in the small experiment table as well as radiative image in blast furnace raceway in some steel corporation. By the laboratory research we obtain that coefficient of correction equals to 33.4 and error value between the measured temperature and calculated temperature is in the scope of 5.0%. The result shows that the temperature fields of gas combustion flame image and those of radiative image in raceway reflect accurately the actual temperatures respectively as well as a series of changes for flame temperature information caused by varying working conditions. Therefore, it lays foundations for furnace operators to provide visualized image information and accurate temperature information.
Uncertainty Propagation from Sensing to Modeling and Control in Buildings - Technical Report (2013)

A fundamental problem in the design of closed-loop Cyber-Physical Systems (CPS) is in accurately capturing the dynamics of the underlying physical system. To provide optimal control for such closed-loop systems, model-based controls require accurate physical plant models. It is hard to analytically establish (a) how data quality from sensors affects model accuracy, and consequently, (b) the effect of model accuracy on the operational cost of model-based controllers. We present the Model-IQ toolbox which, given a plant model and real input data, automatically evaluates the effect of this uncertainty propagation from sensor data to model accuracy to controller performance. We apply the Model-IQ uncertainty analysis for model-based controls in buildings to demonstrate the cost-benefit of adding temporary sensors to capture a building model. Model-IQ's automated process lowers the cost of sensor deployment, model training and evaluation of advanced controls for small and medium sized buildings. Model-IQ provides recommendation of sensor placement and density to trade-off the cost of additional sensors with energy savings by the improved controller performance. Such end-to-end analysis of uncertainty propagation has the potential to lower the cost for CPS with closed-loop model based control. We demonstrate this with real building data in the Department of Energy's HUB.
Design and Synthesis of Semi-Artificial Myoglobin Possessing DNA-Binding Peptides on Heme Propionates (2005)

Abstract Peptides possessing the DNA-binding capability were successfully introduced into myoglobin by a cofactor-reconstitution strategy. We have designed and synthesized an artificial iron–protoporphyrin IX (heme)–peptide conjugate, Heme(br)2, which has covalently conjugated GCN4 basic region peptides at the heme propionate groups as an artificial DNA-binding site. The peptide Heme(br)2 was inserted into apomyoglobin to give a peptide-conjugated myoglobin, Mb(br)2. The UV–vis and circular dichroism spectra of Mb(br)2 were comparable to those of native myoglobin, suggesting that the heme environment and three-dimensional structure of Mb(br)2 were almost identical to those of native myoglobin. The size exclusion chromatography indicated that the Mb(br)2 existed as a monomeric form in an aqueous solution and interacted with its target DNA sequence [c-AMP responsive element (CRE)]. The fluorescence study also revealed that the Mb(br)2 bound CRE DNA effectively with 1/1 stoichiometry [affinity constant; 8.4 (±0.8) × 107 M−1]. Additionally, the CRE DNA-binding enhanced the peroxidase-like activity of Mb(br)2, possibly due to the partial structural perturbation around the heme active-site. These results demonstrate that the chemical modification of prosthetic group with functional peptides can provide a new strategy for the design of semi-artificial proteins with engineered function.

Development of 18F-labeled fibronectin-mimetic peptide for positron emission tomography imaging of 51 integrin expression (2014)

Objective: α5β1 Integrin is a major transmembrane receptor for the extracellular matrix protein fibronectin. It plays important roles in tumor angiogenesis, progression, invasion, and metastasis, relates to the resistance to chemotherapy or ionizing radiation, and correlates with the poor prognosis in several types of cancers. The present study was aimed to develop a fibronectin-mimetic peptide (FMP)-based radioligand and to evaluate its potential for positron emission tomography (PET) imaging of α5β1 integrin expression. Methods: FMP was synthesized based on the reported α5β1-specific peptide sequence (1) and conjugated with the NOTA chelate for labeling with fluorine-18 (18F) using a facile method based on chelation of [18F]aluminum fluoride (2). A negative control probe was also produced by replacement of “G” with “A” in the primary binding motif, Arg-Gly-Asp (RGD) structured in FMP. In vitro cell binding and blocking assays, dynamic PET scans, biodistribution assays, and autoradiography were performed using α5β1-positive B16F10 and α5β1-negative SW48 cell lines and murine tumor models. Results: Both FMP and FMP control could be radiolabeled with a reasonable yield of 20% and with the radiochemical purity of 99%. The radiolabeled peptide was found acceptably stable in murine serum in vitro for at least 1 hr. The relative cell binding ratios of 18F-FMP to α5β1-positive cells obviously increased with increasing of the cell density, while negligible binding was observed with α5β1-negative cells as well as with the negative control probe. The cellular binding of 18F-FMP could be competitively inhibited by unlabeled NOTA-FMP and FMP in a similarly dose-dependent manner. In vivo α5β1-positive B16F10 tumors could be clearly visualized by small animal PET within 2030 min post-injection of 18F-FMP. Dynamic PET showed rapid and predominant clearance of 18F-FMP by urinary excretion, with negligible levels of radioactivity accumulation in normal tissues. Biodistribution studies demonstrated that the tumor uptake of 18F-FMP was significantly higher in α5β1-positive tumors versus α5β1-negative tumors, and as expected the accumulation levels of radioactivity in α5β1-positive tumors was found significantly higher with 18F-FMP versus its negative control. Autoradiography studies of tumor sections further demonstrated the specificity of tissue binding of 18F-FMP. Conclusion: A α5β1-specific fibronectin-mimetic peptide was successfully functionalized as a PET probe for noninvasive visualization and quantitative evaluation of the expression levels of α5β1 integrin in tumors. Our study indicates that 18F-FMP is worth being further optimized by improving its binding activity and pharmacokinetic properties.
Selective Terminal Alkyne Metathesis: Synthesis and Use of a Unique Triple Bonded Dinuclear Tungsten Alkoxy Complex Containing a Hemilabile Ligand (2007)

Abstract The in situ synthesis of new alkyne metathesis catalysts is described, with particular emphasis on the search for tris‐alkoxytungsten‐based terminal alkyne metathesis. In that context, hemilabile, ether‐containing alkoxy ligands have proved to be suitable and have led to the design and use of a sterically hindered hemilable ligand for the synthesis of a well‐defined binuclear, triple‐bonded W≡W complex. This complex is shown to be a highly active and selective catalyst precursor for terminal alkyne metathesis, and allows the unprecedented metathesis of phenylacetylene.
Underwater Suction Gripper for Object Manipulation with an Underwater Robot (2021)

The diversity of end-effectors for manipulation enables a robot to grasp objects with various shapes. As underwater manipulation becomes more common, various types of end-effectors for underwater robots are required. In this paper, we develop an underwater suction gripper (USG) for object manipulation. By using a thruster, the suction force is easily controlled by the electric drive, and the resulting size and weight allow the proposed gripper to be installed on a robot. In the experiments, we evaluate the grasping performance of the USG quantitatively. Furthermore, we installed the USG on an actual underwater robot to perform a manipulation task. The results showed that the USG can perform the pick-and-place task in a shorter and easier grasping motion compared to a typical 2-finger gripper. The implementation code can be found here: https://github.com/kumahika/usg
Current and Future Developments in the Treatment of Virus-Induced Hypercytokinemia (2017)

Emerging pathogenic viruses such as Ebola and Middle Eastern Respiratory Syndrome coronavirus (MERS-CoV) can cause acute infections through the evasion of the host's antiviral immune responses and by inducing the upregulation of inflammatory cytokines. This immune dysregulation, termed a cytokine storm or hypercytokinemia, is potentially fatal and is a significant underlying factor in increased mortality of infected patients. The prevalence of global outbreaks in recent years has offered opportunities to study the progression of various viral infections and have provided an improved understanding of hypercytokinemia associated with these diseases. However, despite this increased knowledge and the study of the infections caused by a range of emerging viruses, the therapeutic options still remain limited. This review aims to explore alternative experimental strategies for treating hypercytokinemia induced by the Ebola, avian influenza and Dengue viruses; outlining their modes of action, summarizing their preclinical assessments and potential clinical applications.
Human Proinsulin C-peptide from a Precursor Overexpressed in &lt;italic&gt;Pichia pastoris&lt;/italic&gt; (2006)

In this article we report the production of human proinsulin C-peptide with 31 amino acid residues from a precursor overexpressed in Pichia pastoris. A C-peptide precursor expression plasmid containing nine C-peptide genes in tandem was constructed and used to transform P. pastoris. Transformants with a high copy number of the C-peptide precursor gene integrated into the chromosome of P. pastoris were selected. In high-density fermentation in a 300 liter fermentor using a simple culture medium composed mainly of salt and methanol, the C-peptide precursor was overexpressed to a level of 2.28 g per liter. A simple procedure was established to purify the expression product from the culture medium. The purified C-peptide precursor was converted into C-peptide by trypsin and carboxypeptidase B joint digestion. The yield of C-peptide with a purity of 96% was 730 mg per liter of culture. The purified C-peptide was characterized by mass spectrometry, N- and C-terminal amino acid sequencing, and sodium dodecylsulfate-polyacrylamide gel electrophoresis.

Effects of Cryogenic Aging on a Rapid Prototyped (RP) Polymer (2002)

Little research has been done on the post-processing (aging) of rapid prototyped (RP) polymers at temperatures below 123K (–238˚F). Test specimens of RP thermosetting resin (DSM-Somos 8110) were fabricated and cryogenically aged from 10-25 hours. The tensile strength and impact toughness were measured. This work will study the effect of cryogenic aging on yield strength of Somos 8110. This paper will also discuss our interpretation of the data based on fractography.
Transaction Mining for Fraud Detection in ERP Systems (2010)

Despite all attempts to prevent fraud, it continues to be a major threat to industry and government. Traditionally, organizations have focused on fraud prevention rather than detection, to combat fraud. In this paper we present a role mining inspired approach to represent user behaviour in Enterprise Resource Planning (ERP) systems, primarily aimed at detecting opportunities to commit fraud or potentially suspicious activities. We have adapted an approach which uses set theory to create transaction profiles based on analysis of user activity records. Based on these transaction profiles, we propose a set of (1) anomaly types to detect potentially suspicious user behaviour, and (2) scenarios to identify inadequate segregation of duties in an ERP environment. In addition, we present two algorithms to construct a directed acyclic graph to represent relationships between transaction profiles. Experiments were conducted using a real dataset obtained from a teaching environment and a demonstration dataset, both using SAP R/3, presently the predominant ERP system. The results of this empirical research demonstrate the effectiveness of the proposed approach.
Utilization of one-line laser scanner for scale estimation of three-dimensional reconstructed model using camera images (2018)

In this paper, we propose a method to estimate the scale of a point cloud model through matching one-line range information with a scale-less three-dimensional model restored from camera images. Range data is obtained with a laser scanner attached to the camera used for image acquisition. Scale estimation is realized by comparing the shape represented by the measurement of the laser scanner and the point cloud, and scale estimates from multiple observations are integrated according to the histogram. The effectiveness of the proposed method was evaluated by experiments.
Oxidation of Alcohols Using Nanocatalysts (2013)

This chapter provides an overview of the heterogeneous catalysts that have been developed for the aerobic oxidation of alcohols. Several advanced heterogeneous nanocatalysts including ruthenium, palladium, and gold active species were shown to have high activity and selectivity for the oxidation of a wide range of alcohols under an atmospheric pressure of oxygen or air. These catalysts were also proven to be reusable without any loss of activity or selectivity. The chapter highlights future issues in the modern aerobic oxidation of alcohols. Bimetallic nanoparticles have attracted enormous attention due to their unique synergistic catalytic properties that cannot be obtained in monometallic nanoparticles.
Avian Macrophages: Contribution to Cellular Microenvironment and Changes in Effector Functions Following Activation (1993)

The capacity of macrophages to generate metabolites and monokines having effector and regulatory functions can result in a major impact on their cellular microenvironment. Macrophage products synthesized in response to bacterial lipopolysaccharide stimulation include reactive oxygen and nitrogen intermediates as well as tumor necrosis factor (TNF). These secreted products of macrophages exhibit bioactivity either locally or systemically. Although the mechanism of action of avian monokines such as TNF-like factor may be similar to their mammalian counterparts, chicken TNF seems to lyse cells of chicken origin and not of mammalian origin. Furthermore, the generation and activity of products such as TNF is directly influenced by environmental stressors such as heat and toxins.
ShapeShifting Screen Media: A Declarative Computational Model for Interactive Reconfigurable Moving Image Narratives (2007)

This paper presents an approach and a computational model, implemented in a software system, for the creation and delivery of interactive moving image productions made with filmed material that level the aesthetic and editing quality of existing linear film and television programmes. They have been validated through a number of productions, notably through a dramatic production delivered on a national television channel in 12 episodes. The focus of the paper is on the declarative formal language, called Narrative Structure Language (NSL), which we developed for the representation of such narratives, and on an accompanying reasoning engine.
Design flow for embedded FPGAs based on a flexible architecture template (2008)

Modern digital signal processing applications have an increasing demand for computational power while needing to preserve low power dissipation and high flexibility. For many applications, the growth of algorithmic complexity is already faster than the growth of computational power provided by discrete general purpose processors. A typical approach to address this problem is the combination of a processor core with dedicated accelerators. Since changes in standards or algorithms can change the demands on the accelerators, an attractive alternative to highly customised VLSI- macros is the use of reconfigurable embedded FPGAs (eFPGAs). First commercial products combining a general purpose processor core and an embedded FPGA recently emerged (e.g. Stretch S6000 Menta eFPGA- augmented CPUs). For many digital signal processing applications, a significantly improved efficiency in terms of power dissipation, throughput and chip area can be achieved by tailoring both the processor core and the reconfigurable accelerator to the given application domain. In this work, a methodology to design highly customisable eFPGA-architectures starting from a high level description is presented. The design framework elaborated during this work enables a physically optimised VLSI-design of the specified eFPGA and aims to support simulation of the according eFPGA-macros both on a functional and netlist-level by providing an elementary configuration tool based on the same high level description as the eFPGA-architecture.
