DELPHI style extraction and validation of compact model for a multichip module package (2015)

DELPHI style compact model generation for single chip packages is an electronics industry standard proposed by the JEDEC council. Such compact network models are boundary condition independent and ensure that junction temperatures are predicted within 10% [7] compared to the predicted detailed package temperatures. These models replace detailed modeling of packages in system level CFD simulations. With the recent trend of packing more and more functionality onto a single package, multi-chip modules (MCM) kind of packages are becoming more prevalent. MCM packages have more than one functional block (chip) and the DELPHI methodology is no longer applicable directly to MCM packages. In this paper, an extended method has been proposed to extract DELPHI style network models for a multi-chip module packages. ANSYS Icepak is used to model and validate the new method by comparing its temperature predictions with a detailed package. The proposed method uses a combination of the JEDEC proposed method and a linear superposition technique to predict junction temperatures of MCM packages. Linear superposition method takes in to account the interdependency of chips with each other, whereas the DELPHI method is based on a boundary condition-independent technique. Also, an additional study is also carried out to understand the effect of proximity of chips and its impact on the comparisons with the detailed CFD model.

Validation of a novel resistance monitoring technique for corn rootworm (Coleoptera: Chrysomelidae) and event DAS‐59122‐7 maize (2008)

Abstract Rootworm control tactics have recently expanded to include transgenic maize, which express insecticidal proteins from Bacillus thuringiensis (Bt) to reduce larval injury and protect yield potential. Exceptional root protection, increased grower efficiency and improved safety have led to rapid adoption of this technology in the USA. As a result, there is a recognized need for resistance management programmes aimed at delaying rootworm resistance. An essential component of resistance management programmes is the development and implementation of effective resistance monitoring techniques. Five test populations of Diabrotica virgifera virgifera (LeConte) were used to evaluate the sensitivity of two techniques used to describe population susceptibility to the Bt proteins expressed in event DAS‐59122‐7 maize: a diet bioassay employing purified proteins applied to artificial diet and a novel technique using sub‐lethal measures of larval development on seedling maize. Test populations included Rochelle‐US, an unselected susceptible colony, three populations composed of 5%, 25% or 50% Rochelle‐S mixed with Rochelle‐US, and the Rochelle‐S selected colony. Rochelle‐S was derived from the same founding population as Rochelle‐US, but selected for survival on DAS‐59122‐7 maize. Selections identified a minor trait conferring increased tolerance, and greenhouse plant efficacy evaluations confirmed that after 10 generations of selection with no random mating, Rochelle‐S caused significantly more root injury to DAS‐59122‐7 than Rochelle‐US. Rochelle‐S present at 5% of the test population resulted in measurable but not significant increase in injury to DAS‐59122‐7 maize. The diet bioassay was relatively insensitive to the susceptibility differences between the Rochelle‐US and Rochelle‐S populations. Neither LC 50 nor EC 50 estimates produced statistically significant differentiation between test populations with 0%, 5%, 25% or 50% Rochelle‐S. The sub‐lethal assay clearly identified differences between Rochelle‐S and Rochelle‐US and an increased rate of larval development was measurable when the test population contained only 5% of Rochelle‐S.
Montgomery thyroplasty implant system. (1997)

A standardized system has been developed to treat unilateral vocal cord paralysis by medialization of the paralyzed cord. The Montgomery Thyroplasty Implant System consists of a medialization implant, measuring devices, and surgical instruments. The surgical instruments are used to locate, measure, and create a window in the thyroid lamina in which the implant is placed. The measuring devices are used to predetermine the correct implant size. There are five sizes for males (8 to 12 mm) and five for females (6 to 10 mm), with the size representing the distance of medialization. The implant consists of a firm, three-tiered base that locks the implant in the cartilage, and a soft, triangular top that serves to medialize the cord. The standardization of the base allows for revision or reversal at a later date without disturbing the window. The thyroplasty system and surgical procedures are described. Preliminary results of 176 patients who have undergone the Montgomery Thyroplasty Implant System procedure are presented.

Pre-Stack Depth Imaging Via Simultaneous Joint Inversion of Seismic, Gravity and Magnetotelluric Data (2007)

C004 Pre-Stack Depth Imaging Via Simultaneous Joint Inversion of Seismic Gravity and Magnetotelluric Data M. De Stefano (Geosystem SRL) & D. Colombo* (Geosystem SRL) SUMMARY The problem of velocity model building for depth-imaging applications (i.e. Pre-Stack Depth Migration) is approached from the point of view of simultaneous Joint Inversion of multiple geophysical domains. For this purpose a general formulation of the joint inversion problem is provided which integrates geological constraints within a data-driven procedure. The method is then applied to synthetic (long offset) seismic data where seismic travel-time residuals (first-break and post-migration Common Image Gather residuals) are jointly inverted with
Ultra Wide Band Erbium-Doped Silica Fiber Amplifier with 80 nm of Bandwidth (1997)

The design of wavelength-division-multiplexed (WDM) systems and optical networks is currently constrained by the limited bandwidth available from erbium-doped fiber amplifiers (EDFAs) because of their nonuniform gain spectra.
Development of the Los Alamos solid-state optical refrigerator (1998)

Laser-induced cooling of a solid by net anti-Stokes fluorescence, first experimentally demonstrated in 1995, can be the basis of a new type of cryocooler, an optical refrigerator. This article describes the physics and design issues of a practical optical refrigerator for operation at 77 K. In particular, the Los Alamos Solid-State Optical Refrigerator (LASSOR) which we are developing would have an operating efficiency comparable to commercial small cryocoolers, be completely vibration-free and operate for years without maintenance.
VersaMatch: Ontology Matching with Weak Supervision (2023)

Ontology matching is crucial to data integration for across-silo data sharing and has been mainly addressed with heuristic and machine learning (ML) methods. While heuristic methods are often inflexible and hard to extend to new domains, ML methods rely on substantial and hard to obtain amounts of labeled training data. To overcome these limitations, we propose VersaMatch , a flexible, weakly-supervised ontology matching system. VersaMatch employs various weak supervision sources, such as heuristic rules, pattern matching, and external knowledge bases, to produce labels from a large amount of unlabeled data for training a discriminative ML model. For prediction, VersaMatch develops a novel ensemble model combining the weak supervision sources with the discriminative model to support generalization while retaining a high precision. Our ensemble method boosts end model performance by 4 points compared to a traditional weak-supervision baseline. In addition, compared to state-of-the-art ontology matchers, VersaMatch achieves an overall 4-point performance improvement in F1 score across 26 ontology combinations from different domains. For recently released, in-the-wild datasets, VersaMatch beats the next best matchers by 9 points in F1. Furthermore, its core weak-supervision logic can easily be improved by adding more knowledge sources and collecting more unlabeled data for training.
Development and characterization of hydrocarbon polyol polyurethane and silicone magnetorheological polymeric gels (2004)

Abstract Magnetorheological polymeric gels (MRPG) have been developed for use in semi‐active magnetorheological fluid (MRF) dampers and other magnetorheological (MR) devices. The novel MRPGs are prepared by suspending iron particles in polymeric gels. Off‐state (i.e, no applied magnetic field) viscosity and settling behavior can be controlled through the selection of polymeric gels. In this study, tunable rheological properties were investigated with a piston‐driven flow type rheometer with a shear rate varying from 20 s −1 to 6,000 s −1 . Silicone MRPG (with 84.5 wt % iron particles) has controllable viscosity and a high shear yield stress over a wide range of shear rates. Silicone MRPG (79.5 wt % iron particles) has the lowest viscosity of those studied. Polyurethane MRPG has the lowest settling rate. The order of addition of magnetic particles and polymer during the polymerization process affects the MRPG final off‐state apparent viscosity (80% increase in apparent viscosity for silicone MRPG polymerized after adding iron particles). This indicates that polymer gels modify the surface properties of the magnetic particles, causing interaction among particles. The dynamic shear yield stress is higher for fluids with better dispersion stability. Polyurethane MRPG, which has the lowest settling rate, has a high dynamic yield stress (23 kPa at 350 mT). Both dynamic and static shear stress values of the MRPGs were found to be similar in magnitude (5–8 kPa at 120 mT for silicone MRPG with 84.5 wt % iron particles and polyurethane MRPG), indicating that MRPGs can provide consistent performance in devices. © 2004 Wiley Periodicals, Inc.

Frequency compensation for in-ear noise dosimetry (2023)

Personal noise dosimeters (PNDs) are used in the prevention of noise induced hearing loss (NIHL) by monitoring noise exposure. Exposure of a worker is typically estimated by measuring the noise level at the shoulder location and subtracting the estimated protection provided by any worn hearing protection devices. Current noise dosimeters in the marketplace are deficient because the noise level at the shoulder does not necessarily represent the noise exposure in the ear canal due to shadowing, canal resonances and other acoustical phenomena. Moreover, workers often deliberately insert earplugs to shallow canal depths to better hear their environments, and earmuff attenuation is inconsistent due to variations in head geometry. Thus, the estimated hearing protection is often in error. In-ear personal noise dosimeters (iPNDs) can solve these problems because they incorporate a microphone within a hearing protection earplug that measures the actual noise level in an ear canal. However, the acoustics of the in-ear measurement are quite different compared to the shoulder measurement, and in-ear measurements must be frequency compensated to achieve valid results. This paper discusses in-ear noise dosimetry, why frequency compensation is needed and how to compensate the microphone signal. [This work was funded by a CDC SBIR grant.]
Dynamic Radio Resource Management for OFDMA-Based Relay Enhanced Cellular Network (2011)

Relay technology is one of the technologies that will enhance user experience in the next generation cellular networks. One of the goals (and characteristics) of successful cellular network design is availability of services to all subscribed users irrespective of their location. Designing a good Radio Resource Management (RRM) is essential in achieving that goal. In this paper we propose a dynamic resource partitioning in the OFDMA-based Relay Enhanced Networks. We study performance of the proposed RRM scheme with fairness and maximum throughput objectives and show that it has superior performance in comparison with conventional RRM schemes.
Detecting controversy on the web (2013)

A useful feature to facilitate critical literacy would alert users when they are reading a controversial web page. This requires solving a binary classification problem: does a given web page discuss a controversial topic? We explore the feasibility of solving the problem by treating it as supervised k-nearest-neighbor classification. Our approach (1) maps a webpage to a set of neighboring Wikipedia articles which were labeled on a controversiality metric; (2) coalesces those labels into an estimate of the webpage's controversiality; and finally (3) converts the estimate to a binary value using a threshold. We demonstrate the applicability of our approach by validating it on a set of webpages drawn from seed queries. We show absolute gains of 22% in F_0.5 on our test set over a sentiment-based approach, highlighting that detecting controversy is more complex than simply detecting opinions.
Continuous Air Monitoring Using Inductively Coupled Plasma Atomic Emission Spectrometry: Correction of Spectral Interferences Arising from CN Emission (1998)

Introduction of sample stream air into an argon inductively coupled plasma permits continuous monitoring of hazardous air pollutant metals in combustion flue gases. Along with entrained particulates and metal vapors, various molecular components of the flue gas are introduced into the plasma. These species, and reaction products thereof, also undergo excitation resulting in complex emission spectra of appreciable intensity. Serious spectral interferences arise for several metal elements, from molecular emission bands associated with the stable CN radical and other polyatomic species. Failure to account for these interferences can significantly degrade accuracy particularly at low flue gas metal concentrations. Reported here is an effective method for measurement and correction of CN spectral interferences affecting the on-line detection of hazardous air pollutant metals that incorporates conventional polychromator hardware and existing instrument software capabilities. A demonstration of the ability of this method to achieve virtually complete correction of these interferences under both laboratory and field conditions is presented.
Simplified Generation of High-Angular-Momentum Light Beams (2007)

A simplified method of generating a beam of light having a relatively high value of angular momentum (see figure) involves the use of a compact apparatus consisting mainly of a laser, a whispering- gallery-mode (WGM) resonator, and optical fibers. The method also can be used to generate a Bessel beam. ( Bessel beam denotes a member of a class of non-diffracting beams, so named because their amplitudes are proportional to Bessel functions of the radii from their central axes. High-order Bessel beams can have high values of angular momentum.) High-angular-momentum light beams are used in some applications in biology and nanotechnology, wherein they are known for their ability to apply torque to make microscopic objects rotate. High-angular-momentum light beams could also be used to increase bandwidths of fiber-optic communication systems. The present simplified method of generating a high-angular-momentum light beam was conceived as an alternative to prior such methods, which are complicated and require optical setups that include, variously, holograms, modulating Fabry-Perot cavities, or special microstructures. The present simplified method exploits a combination of the complex structure of the electromagnetic field inside a WGM resonator, total internal reflection in the WGM resonator, and the electromagnetic modes supported by an optical fiber. The optical fiber used to extract light from the WGM resonator is made of fused quartz. The output end of this fiber is polished flat and perpendicular to the fiber axis. The input end of this fiber is cut on a slant and placed very close to the WGM resonator at an appropriate position and orientation. To excite the resonant whispering- gallery modes, light is introduced into the WGM resonator via another optical fiber that is part of a pigtailed fiber-optic coupler. Light extracted from the WGM resonator is transformed into a high-angular- momentum beam inside the extraction optical fiber and this beam is emitted from the polished flat output end. By adjusting the geometry of this apparatus, it is possible to generate a variety of optical beams characterized by a wide range of parameters. These beams generally have high angular momenta and can be of either Bessel or Bessel-related types.
Diesel Exhaust Emissions Control for Light Duty Vehicles (2003)

<div class="htmlview paragraph">The objective of this paper is to present the results of diesel exhaust aftertreatment testing and analysis done under the FreedomCAR program. Nitrogen Oxides (NOx) adsorber technology was selected based on a previous investigation of various NOx aftertreatment technologies including non-thermal plasma, NOx adsorber and active lean NOx. Particulate Matter (PM) emissions were addressed by developing a catalyzed particulate filter. After various iterations of the catalyst formulation, the aftertreatment components were integrated and optimized for a light duty vehicle application.</div> <div class="htmlview paragraph">This compact exhaust aftertreatment system is dual leg and consists of a sulfur trap, NOx adsorbers, and catalyzed particulate filters (CPF). During regeneration, supplementary ARCO ECD low-sulfur diesel fuel is injected upstream of the adsorber and CPF in the exhaust. Steady state and transient emission test results with and without the exhaust aftertreatment system (EAS) are presented. Results of soot filter regeneration by injecting low-sulfur diesel fuel and slip of unregulated emissions, such as NH<sub>3</sub>, are discussed. Effects of adsorber size and bypass strategy on NOx conversion efficiency and fuel economy penalty are also presented in this paper. The results indicate that if the supplementary fuel injection is optimized, NH<sub>3</sub> slip is negligible. During the FTP cycle, injection of low sulfur diesel fuel can create temperature exotherms high enough to regenerate a loaded CPF. With the optimized NOx adsorber regeneration strategies the fuel injection penalty can be reduced by 40 to 50%. Results for various other issues like low temperature light off, reductant optimization, exhaust sulfur management, system integration and design trade-off, are also presented and discussed in this paper.</div>
High Density Fabrication Process for Single Flux Quantum Circuits (2023)

We implemented, optimized and fully tested over multiple runs a superconducting Josephson junction fabrication process tailored for the integrated digital circuits that are used for control and readout of superconducting qubits operating at millikelvin temperatures. This process was optimized for highly energy efficient single flux quantum (ERSFQ) circuits with the critical currents reduced by factor of ~10 as compared to those operated at 4.2 K. Specifically, it implemented Josephson junctions with 10 uA unit critical current fabricated with a 10 uA/um2 critical current density. In order to circumvent the substantial size increase of the SFQ circuit inductors, we employed a NbN high kinetic inductance layer (HKIL) with a 8.5 pH/sq sheet inductance. Similarly, to maintain the small size of junction resistive shunts, we used a non-superconducting PdAu alloy with a 4.0 ohm/sq sheet resistance. For integration with quantum circuits in a multi-chip module, 5 and 10 um height bump processes were also optimized. To keep the fabrication process in check, we developed and thoroughly tested a comprehensive Process Control Monitor chip set.
A Wide Dynamic Range CMOS Image Sensor with Gated Charge Storage and a Multiple Sampling Technique (2006)

A wide dynamic range CMOS image sensor which has a photodiode and a gated storage diode in each pixel is proposed. The storage diode outputs with short accumulation time are read out for multiple times, and the photodiode output and the multiple-sampled storage diode outputs are synthesized in an external system. A separation gate is used to control the charge flow to the storage diode. The proposed technique allows very wide dynamic range imaging with less motion artifact. The operation of the proposed pixel device structure is simulated and an experimental CMOS image sensor is implemented in 0.18 mum CMOS image sensor technology.
WebTalk: mining Websites for automatically building dialog systems (2004)

The task of creating customized spoken dialog applications has traditionally been known to be expensive, requiring significant resources and a certain level of expertise. This is clearly an obstacle in porting and scaling dialog systems especially those required for customer care and help desk applications. This paper describes WebTalk - a technique for automatically creating spoken and text-based customer-care dialog applications solely based on a company's Website. Our goal is to create task oriented dialog services by automatically learning the task knowledge and mining information present on corporate Websites. In this paper, we discuss the motivation and the feasibility of creating such a technique and present an overview of the main components of WebTalk. We address some of the challenges and present methods for evaluating such a system.
In Vitro Selection of RNA Aptamers to a Protein Target by Filter Immobilization (2000)

This unit describes the selection of aptamers from a pool of single-stranded RNA by binding to a protein target. Aptamers generated from this selection experiment can potentially function as protein inhibitors, and may find applications as therapeutic or diagnostic reagents. A pool of dsDNA is used to generate a ssRNA pool, which is mixed with the protein target. Bound complexes are separated from unbound reagents by filtration, and the RNA:protein complexes are amplified by a combination of reverse transcription, PCR, and in vitro transcription.
