Measurement Uncertainty Analysis of an Accelerometer Calibration Using a POC Electromagnetic Launcher (2012)

A pulse forming network (PFN), helical electromagnetic launcher (HEML), command module (CM), and calibration table (CT) were built and evaluated for the combined ability to calibrate an accelerometer. The PFN has a maximum stored nergy of 19.25 kJ bank and is fired by a silicon controlled rectifier (SCR), with appropriate safety precautions. The HEML is constructed out of G-10 fiberglass reinforced epoxy and is designed to accelerate a mass of 600 grams to a velocity of 10 meters per second. The CM is microcontroller-based running Arduino Software. The CM has a keypad input and 7 segment outputs of the PFN voltage and desired charging voltage. After entering a desired PFN voltage, the CM controls the charging of the PFN. When the two voltages are equal it sends a pulse to the SCR to fire the PFN and in turn, the HEML. The HEML projectile’s tip hits a target that is held by the CT. The CT consists of a table to hold the PFN and HEML, a vacuum chuck, air bearing, velocimeter and catch pot. The target is held with the vacuum chuck awaiting impact. After impact, the air bearing allows the target to fall freely so that the velocimeter can accurately read. A known acceleration is determined from the known change in velocity of the target. Thus, if an accelerometer was attached to the target, the measured value can be compared to the known value.
Online drug interaction surveillance (1975)

An online computer-based system to monitor prospectively for potential drug interactions in a hospital setting is described. The system, developed at Stanford University Medical Center, is fully operational and is used to inform pharmacists, nurses and physicians as to the severity and speed of onset of potential drug interactions. In addition, the system can produce prescription labels and patient-drug profiles for the pharmacy and serves as a retrieval source of drug interaction information. Each report provides information regarnding the pharmacological effect and mechanism of the interactions, as well as statements involving relevant clinical findings associated with these interactions.

Elliptic curve cryptosystems using curves of smooth order over the ring Z/sub n/ (1997)

We present a new cryptosystem based on elliptic curves over the ring Z/sub n/, where n=pq, in which the message is held in the exponent and not the group element. The security of this system is based on the difficulty of factoring n. A digital signature scheme and ID-based key exchange system are also given.
The Development of User Models for a Telecommunications Environment (1999)

This paper examines a method for the development of user models for a telecommunication computer system used during service and sales negotiations. User models enhance the requirements gathering phase of system design by capturing the diversity of the user population and capitalizing on the variety of distinguishable and categorical strategies that affect performance. The CDM method (Categorizing, Describing, and Modeling method) was developed as a technique to generate user models. In the CDM method, the user population is first categorized into a reasonable number of groups. Next, the behaviors for each group are described and are then qualitatively and quantitatively modeled. These models are subsequently used during the system design and operational process to optimize performance for all users. This paper is the second in a series designed to apply the CDM method and focuses on the latter sections of the CDM method, namely describing and modeling groups of users.
An Improved Incremental Al Prime Implicates (1992)

Prime implicates have become a widely used tool in AI. The prime implicates of a set of clauses can be computed by repeatedly resolving pairs of clauses, adding the resulting resolvents to the set and removing subsumed clauses. Unfortunately, this brute-force approach performs far more resolution steps than necessary. Tison provided a method to avoid many of the resolution steps and Kean and Tsiknis developed an optimized increment al version. Unfortunately, both these algorithms focus only on reducing the number of resolution steps required to compute the prime implicates. The actual running time of the algorithms depends critically on the number and expense of the subsumption checks they require. This paper describes a method based on a simplification of Kean and Tsiknis ’ algorithm using an entirely different data structure to represent the data base of clauses. The new algorithm uses a form of discrimination net called tries to represent the clausal data base which produces an improvement in running time on all known examples with a dramatic improvement in running time on larger examples. 1
Uniform Cellular Automata Linear Rules for Edge Detection (2013)

In this paper we discuss the application of two-dimensional linear cellular automata rules to the problems of edge detection in monochromatic images. We proposed an efficient and simple method of edge detection based on uniform cellular automata transition matrix representation. We investigate of cellular automata linear rules for edge detection by using matrix representation, in some cases they are strong and some other rules are not in fact useful for practical edge detection. All rules give computationally effective result since the computation mechanism consist only matrix multiplication. Finally, we present some results of the proposed linear rules for edge detection and compare with some classical results.
OLIMPO: A balloon-borne, arcminute-resolution survey of the sky at mm and sub-mm wavelengths (2003)

We describe OLIMPO, a balloon-borne telescope devoted to cosmological and astrophysical surveys in the mm and sub-mm range. We summarize the relevant science (principally surveys of SZ clusters, of the sub-mm cosmic background and observations of galactic and cirrus dust) and the innovative sub-systems we have developed. The test flight of the telescope is planned for July 2004; the long duration flight is planned for the end of 2005.
Typical Physicochemical Behaviors of Chitosan in Aqueous Solution (2003)

Physicochemical properties of a homogeneous series of chitosans with different degrees of acetylation and almost the same degree of polymerization were investigated in an ammonium acetate buffer. Techniques such as interferometry, static light scattering (in batch or coupled on line with a chromatographic system), and viscometry were processed. All of the results agree with a unique law of behavior only depending on the degree of acetylation of the polymer. Indeed, values of the refractive index increment, radius of gyration, second viral coefficient, and intrinsic viscosity are decreasing in the same way as DA is increasing. Three distinct domains of DA were defined and correlated to the different behaviors of chitosans: (i) a polyeletrolyte domain for DA below 20%; (ii) a transition domain between DA = 20% and 50% where chitosan loses its hydrophilicity; (iii) a hydrophobic domain for DAs over 50% where polymer associations can arise. Conformations of chitosan chains were studied by the calculations of the persistence lengths (L(p)). The average value was found to be close to 5 nm, in agreement with the wormlike chain model, but no significant variation of L(p) with the degree of acetylation was noticed.
Simple Secondary Radar for Non-Line-of-Sight Pedestrian Detection (2019)

This paper proposes a secondary radar for detection of hidden pedestrians. A transponder carried by a pedestrian responds to a radio-wave transmitted from a car. The distance between the transponder and the car can be measured by using a phase detection scheme, where the frequency detected radio-wave is doubled at the receiver.
Routes to calcified porous silicon: implications for drug delivery and biosensing (2003)

This work describes methods for the fabrication of calcium phosphate films on crystalline silicon substrates, with the long-term goal of employing such materials in either drug delivery or sensing applications. The emphasis of this particular account encompasses both film fabrication as well as surface modification strategies relevant to the sensing of bio-molecular species. For the former, a new process for calcium phosphate film formation is described entailing the use of a high energy DC spark onto silicon surfaces in the presence of Ca10(PO4)6(OH)2. For sensing purposes, routes to modification of the calcium phosphate/porous silicon surface have been achieved via the use of bifunctional bisphosphonate derivatives, with proof-of-concept demonstrated by the covalent attachment of fluorescent fluorescein tags.
High-speed sense circuit techniques for a 1-mbit BiCMOS cache SRAM (1998)

This paper describes a high-speed and low-power 1-Mbit BiCMOS cache SRAM sense circuit fabricated using a 0.5-μm BiCMOS process technology. By using the quasi-6 module structure, switching between 18- and 36-bit output can be carried out without access delay. Because of the development of a sense circuit with a low-amplitude current amplifier and equalization/write-recovery circuit, the sense delay is 0.8 ns, which is 50% faster than the conventional common collector configuration. Using this new technique, a 1-Mbit BiCMOS cache SRAM for 4.5-ns cycle operation was fabricated. © 1998 Scripta Technica, Electron Comm Jpn Pt 2, 81(8): 55–63, 1998
GeoSneakPique: Visual Autocompletion for Geospatial Queries (2021)

How many crimes occurred in the city center? And exactly which part of town is the “city center”? While location is at the heart of many data questions, geographic location can be difficult to specify in natural language (NL) queries. This is especially true when working with fuzzy cognitive regions or regions that may be defined based on data distributions instead of absolute administrative location (e.g., state, country). GeoSneakPique presents a novel method for using a mapping widget to support the NL query process, allowing users to specify location via direct manipulation with data-driven guidance on spatial distributions to help select the area of interest. Users receive feedback to help them evaluate and refine their spatial selection interactively and can save spatial definitions for re-use in subsequent queries. We conduct a qualitative evaluation of the GeoSneakPique that indicates the usefulness of the interface as well as opportunities for better supporting geospatial workflows in visual analysis tasks employing cognitive regions.
The mobility minima in pulsed-field capillary electrophoresis of large DNA (1995)

Pulsed-field capillary electrophoresis represents a new tool for rapid and highly efficient separations of large biopolymers. The method has been utilized here to study dependencies of the electrophoretic mobility upon the frequency and pulse shape of applied voltage for large, double-stranded DNA molecules (5-100 kb) migrating in neutral polymer solutions. Two different shapes of alternating electric field (sine- and square-wave impulses) were examined with the frequency values ranging from 1 to 30 Hz. The linear dependence between duration of the forward pulse (at which the DNA molecule experiences a minimum mobility) and the product N.In(N) (where N is the number of base pairs) was experienced in field-inversion gel electrophoresis, while exponential dependence was found with the sinusoidal electric field. The mobility minima were lower in field-inversion electrophoresis than with the biased sinusoidal-field technique. The DNA (5 kb concatamers) was adequately separated using a ramp of frequency in the square-wave electric field, in approximately 1 h. The migration order of DNA fragments was referenced through adding a monodisperse DNA (48.5 kb) into the sample. The band inversion phenomena were not observed under any experimental conditions used in this work.
Effects of Adsorption Group and Molecular Weight of Viscosity-Modifying Admixtures on the Properties of Cement Paste (2022)

To explore the potential application of high-performance viscosity-modifying admixtures (VMAs) is of great importance. In this work, the effects of the adsorption group and molecular weight of VMAs on the properties of fresh cement paste were studied. A series of copolymers having similar molecular weights but different adsorption groups (carboxyl, sulfonic, and quaternary ammonium groups) were compared for the first time. A series of copolymers having the same chemical structure but different molecular weights were also compared. The adsorption, fluidity, bleeding, and rheological properties of the fresh cement paste mixed with different copolymers were tested. The results show that the copolymer, having stronger adsorption group (carboxyl group) and higher molecular weight, could decrease the bleeding and fluidity while enhancing the stability of the fresh cement paste more effectively. The study may help explore ideal materials for the design and preparation of synthetic polymer VMAs.
FOXC1 is Over‐expressed and is More Stable in Triple Negative/Basal‐Like Breast Cancer (2018)

Rapidly accumulating evidence implicates forkhead box C1 ( FOXC1 ) in Triple Negative Breast Cancer (TNBC), particularly in Basal‐Like Breast cancer (BLBC). Recently additional studies have demonstrating that FOXC1 is also a major player in hepatocellular carcinoma (HCC), endometrial cancer, Hodgkin's lymphoma (HL), non‐Hodgkin's lymphoma (NHL), and others. The FOXC1 gene encodes a transcription factor that is crucial to mesodermal, neural crest, and ocular development. Loss of function mutations in FOXC1 have been shown to cause autosomal dominantly inherited Axenfeld‐Rieger's Syndrome (ARS), a developmental disorder associated in eye anomalies and glaucoma. Interestingly, while FOXC1 missense mutations that cause ARS reduce FOXC1 activity, increased FOXC1 function now appears to be often linked to more aggressive cancer phenotypes in TN/BL‐BC, HCC, HL, and NHL. We have investigated the mechanism(s) by which FOXC1 activity is increased in BLBC. Samples were obtained from TNBC tumors, Triple Positive Breast Cancer (TPBC) tumors or from breast tissue from normal patients. Using quantitative PCR, we found that FOXC1 was significantly over‐expressed in TNBC patients as compared to controls. In contrast, FOXC1 mRNA was significantly less expressed in TPBC samples as compared to either control or TNBC samples. FOXC1 protein half‐life was significantly longer in the TNBC/BLBC cell lines (HS 587T and BT 549) compared to FOXC1 protein's half‐life in HeLa cells. Studies of FOXC1 Copy‐number variation (CNV) in TNBC/BLBC cell lines reveals that cell lines that have higher levels of FOXC1 protein (HS 587T, BT‐549) have extra copies of FOXC1 . This contrasts with a cell line with lower expression of FOXC1 protein, MDA‐MB‐231, which may be explained by a deletion of FOXC1 in this TNBC cell line. Our results suggest that increased FOXC1 function in TNBC/BLBC results from over‐expression of FOXC1 in tumors of TNBC patients that appears to be the result of changes to FOXC1 stability and amplification of FOXC1 copy number. We predict that understanding the mechanism(s) underlying FOXC1's activation in cancer could aid in designing improved therapies for TNBC patients.

Batch mode micro-EDM for high-density and high-throughput micromachining (2002)

This paper examines scaling issues for electrode arrays used in micro-electro-discharge machining (micro-EDM). In particular, it explores constraints in the fabrication and usage of high aspect ratio LIGA-fabricated electrode arrays, as well as the limits imposed by the pulse discharge circuits on machining rates. A LIGA-fabricated array of 400 Cu electrodes with 20 /spl square/m diameter was used to machine through-holes in 50 /spl square/m thick stainless steel. An array of multi-layer structures that included tapered shapes was fabricated by the sequential use of three electrode arrays of varying shape. The electrode fabrication and usage for these efforts are described. With respect to the pulse discharge circuits, it is shown that the machining time can be reduced by >50% by dividing the electrode array into sections have independent control of pulse discharge timing. This is implemented by using individual RC timing circuits for each section. A correlation between electrode area per RC circuit and machining rate is described.
Electron reconstruction and identification efficiency measurements with the ATLAS detector using the 2011 LHC proton–proton collision data (2014)

Many of the interesting physics processes to be measured at the LHC have a signature involving one or more isolated electrons. The electron reconstruction and identification efficiencies of the ATLAS detector at the LHC have been evaluated using proton-proton collision data collected in 2011 at [Formula: see text] TeV and corresponding to an integrated luminosity of 4.7 fb[Formula: see text]. Tag-and-probe methods using events with leptonic decays of [Formula: see text] and [Formula: see text] bosons and [Formula: see text] mesons are employed to benchmark these performance parameters. The combination of all measurements results in identification efficiencies determined with an accuracy at the few per mil level for electron transverse energy greater than 30 GeV.
Wireless Control of Modular Multilevel Converter Submodules With Communication Errors (2021)

Wireless control of modular multilevel converter (MMC) submodules can benefit from different points of view, such as lower converter cost and shorter installation time. In return for the advantages, the stochastic performance of wireless communication networks necessitates an advanced converter control system immune to the losses and delays of the wirelessly transmitted data. This article proposes an advancement to the distributed control of MMCs to be utilized in wireless submodule control. Using the proposed method, the operation of the MMC continues smoothly and uninterruptedly during wireless communication errors. The previously proposed submodule wireless control concept relies on implementing the modulation and individual submodule-capacitor-voltage control in the submodules using the insertion indices transmitted from a central controller. This article takes the concept as a basis and introduces to synthesize the indices autonomously in the submodules during the communication errors. This new approach allows the MMC continue its operation when one, some, or all submodules suffer from communication errors for a limited time. The proposal is validated experimentally on a laboratory-scale MMC.

Data fusion and classification using a hybrid intrinsic cellular inference network (2010)

Hybrid Intrinsic Cellular Inference Network (HICIN) is designed for battlespace decision support applications. We developed an automatic method of generating hypotheses for an entity-attribute classifier. The capability and effectiveness of a domain specific ontology was used to generate automatic categories for data classification. Heterogeneous data is clustered using an Adaptive Resonance Theory (ART) inference engine on a sample (unclassified) data set. The data set is the Lahman baseball database. The actual data is immaterial to the architecture, however, parallels in the data can be easily drawn (i.e., "Team" maps to organization, "Runs scored/allowed" to Measure of organization performance (positive/negative), "Payroll" to organization resources, etc.). Results show that HICIN classifiers create known inferences from the heterogonous data. These inferences are not explicitly stated in the ontological description of the domain and are strictly data driven. HICIN uses data uncertainty handling to reduce errors in the classification. The uncertainty handling is based on subjective logic. The belief mass allows evidence from multiple sources to be mathematically combined to increase or discount an assertion. In military operations the ability to reduce uncertainty will be vital in the data fusion operation.
Extended bandwidth management mechanism among multi-OLTs (2007)

Passive optical networks (PON) is being considered as a promising solution for next generation broadband access network due to the convergence of broad bandwidth and low-cost fiber infrastructure along with its ability to successfully support IP-based multimedia applications. PON system has its individual bandwidth allocation mechanism compared with core network allocating bandwidth based on service priority level. However, no uniform bandwidth allocation mechanism from access network to care network. In this paper we propose a novel method of extended bandwidth allocation mechanism among multi-PON systems; then extended dynamic bandwidth allocation (DBA) algorithm in a Gigabit-capable PON (GPON) system for core network is presented. The bandwidth management mechanism among multi-optical line terminals (OLTs) can provide an end-to-end bandwidth guarantee for data transmission. We conduct detailed simulation experiments to study the performance and validate the effectiveness of the proposed method.
A Synthetic Small Molecule That Induces Neuronal Differentiation of Adult Hippocampal Neural Progenitor Cells (2005)

Brain power: An image-based screen of a chemical library was carried out to identify molecules that regulate the differentiation of adult rat hippocampal neural stem cells. Neuropathiazol (1) induces selective neuronal differentiation and competitively suppresses astrocyte differentiation. This compound should be a useful tool to study the processes that control stem-cell fate both in vitro and in vivo.
Cognitive Enhancers (Nootropics). Part 1: Drugs interacting with Receptors. Update 2014 (2014)

Scientists working in the fields of Alzheimer's disease and, in particular, cognitive enhancers are very productive. The review "Cognitive enhancers (nootropics): drugs interacting with receptors" was accepted for publication in July 2012. Since then, new targets for the potential treatment of Alzheimer's disease were identified. This update describes drugs interacting with 42 receptors versus 32 receptors in the first paper. Some compounds progressed in their development, while many others were discontinued. The present review covers the evolution of research in this field through March 2014.
