Effects of Anisotropy Field and Easy Axis Dispersions on Squareness Ratio for HDDR-Processed Nd-Fe-B Powders (2018)

Nd-Fe-B magnetic powders produced by the hydrogenation-decomposition-desorption-recombination process have a lower squareness ratio than sintered magnets. In this paper, the anisotropy field (H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</sub> ) distribution was assumed to be a horizontally flipped lognormal distribution and the effect of the H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</sub> dispersion on the squareness ratio was investigated by using a micromagnetic simulator. As a result, the squareness ratio was very similar to the experimental demagnetization loop, when (H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</sub> ) was 5500 kA/m and σ H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</sub> /(H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</sub> ) was 30%. Moreover, we investigated the easy axis dispersion of grains on squareness ratio in consideration of soft magnetic or nonmagnetic grain boundaries. As a result, the squareness ratio for the nonmagnetic grain boundary was closer to the experimental value; however, it is difficult to describe the experimental demagnetization loop by only considering the easy axis dispersion.
Nanolasers to enable data storage beyond 10Tbit∕in.2 (2007)

A focused ion beam (FIB) fabricated nanolaser is demonstrated to be able to focus light with power of over 250nW into a 30nm spot. To fabricate a nanolaser, a 100nm thick aluminum film was deposited on the emitting edge of a diode laser. FIB was used to etch various apertures into the film. The power was measured by a scanning near-field optical microscope in the near-field regime with a 10nm separation between the probe and the air bearing surface of the nanolaser. Out of four different shapes under study, “C”-shape aperture was found to have the highest throughput.
<title>High-temperature 1.55-um vertical-cavity lasers through wafer fusion</title> (1997)

In this work we report on 64 degree celsius continuous-wave operation of a 1.5 micrometer vertical cavity laser. This laser consists of two fused Al(Ga)As/GaAs mirrors with a strain-compensated InGaAsP/InP active region. Selective lateral oxidation is used for current confinement. Minimum room temperature threshold current is as low as 0.8 mA, and maximum cw output power is as high as 1 mW at 15 degrees Celsius. Pulsed operation is achieved up to 100 degrees Celsius.
Encircled Angular Flux Representation of the Modal Power Distribution and Its Behavior in a Step Index Multimode Fiber (2016)

The optical properties of inline optical components inserted at the input to a multimode optical fiber (MMF) strongly affect the propagating modal power distribution (MPD). To realize stable systems with predictable reproducible performance and to encourage widespread use of MMF systems, improvements to the system design process and to the characterization process need to be made and new interface standards need to be defined. To this end, we have developed a new reproducible MPD measurement and representation together with its theoretical definition. By modifying the encircled flux (EF) representation, which is based on the near-field pattern of a graded-index multimode optical fiber (GI-MMF), we define the encircled angular flux (EAF) for step-index multimode optical fibers (SI-MMFs) based on their far-field patterns (FFPs). Using a SI-MMF, which is used for low cost short distance interconnects, as an example, we show the changes in the MPD along the fiber, reveal an unusual insertion loss-increasing phenomenon due to the evanescent tails of the core modes extending into the cladding, and characterize the equilibrium mode distribution (EMD) in the fiber. The EAF representation enables these phenomena to be quantified. We also propose an EAF template that consists of the target EMD and its tolerance. If device system designers use the EAF template to set the launch conditions, they can perform a fair assessment of the components, and they can design the system performance even if some components are replaced with others from a different supplier manufactured by a different method. We call this concept “Total MPD Management.”

PIM Flooding Mechanism and Source Discovery for BIER (2018)

PIM Flooding Mechanism and Source Discovery (PFM-SD) is a mechanism
for source discovery within a PIM domain. PIM signaling over BIER has
been defined, allowing for BIER to interoperate with PIM. This
document defines PFM-SD over BIER, such that PFM-SD can be used by PIM
in a PIM domain to discover sources that are reachable via BIER. Also,
this document provides PFM-SD extensions to discover the BIER ingress
router closest to the source. This can be used by BIER overlays, such
as PIM signaling over BIER, to determine which router to signal.

Interventional C-arm tomosynthesis for vascular imaging: initial results (2015)

As percutaneous endovascular procedures address more complex and broader disease states, there is an increasing need for intra-procedure 3D vascular imaging. In this paper, we investigate C-Arm 2-axis tomosynthesis (“Tomo”) as an alternative to C-Arm Cone Beam Computed Tomography (CBCT) for workflow situations in which the CBCT acquisition may be inconvenient or prohibited. We report on our experience in performing tomosynthesis acquisitions with a digital angiographic imaging system (GE Healthcare Innova 4100 Angiographic Imaging System, Milwaukee, WI). During a tomo acquisition the detector and tube each orbit on a plane above and below the table respectively. The tomo orbit may be circular or elliptical, and the tomographic half-angle in our studies varied from approximately 16 to 28 degrees as a function of orbit period. The trajectory, geometric calibration, and gantry performance are presented. We overview a multi-resolution iterative reconstruction employing compressed sensing techniques to mitigate artifacts associated with incomplete data reconstructions. In this work, we focus on the reconstruction of small high contrast objects such as iodinated vasculature and interventional devices. We evaluate the overall performance of the acquisition and reconstruction through phantom acquisitions and a swine study. Both tomo and comparable CBCT acquisitions were performed during the swine study thereby enabling the use of CBCT as a reference in the evaluation of tomo vascular imaging. We close with a discussion of potential clinical applications for tomo, reflecting on the imaging and workflow results achieved.

We report on DFB and DBR lasers formed from a wavelength insensitive multi-segmented silicon nitride waveguide. Using a five-segment waveguide, we obtain lasing in erbium-doped DBR (-3.6 dBm) and DFB (-7.3 dBm) cavities.
Preparation and characterisation of thermomechanical properties of sol-gel derived glasses in the PbO-SiO2-B2O3-ZnO system (1995)

Silicate glasses with high contents of lead oxide are for example used as optical glasses and as solder glasses. In spite of the numerous usabilities their manufacturing is sometimes difficult, since these melts are chemically aggressive, and the evaporation of lead during melting cannot be avoided. The sol-gel process may be assumed to be an alternative preparation route, since lower temperatures can be used and more homogeneous glasses can be obtained. Thus mixing problems of SiO2 and PbO due to very different densities could be avoided.
Comparative genome sequencing of Drosophila pseudoobscura : Chromosomal, gene, and cis -element evolution (2005)

We have sequenced the genome of a second Drosophila species, Drosophila pseudoobscura, and compared this to the genome sequence of Drosophila melanogaster, a primary model organism. Throughout evolution the vast majority of Drosophila genes have remained on the same chromosome arm, but within each arm gene order has been extensively reshuffled, leading to a minimum of 921 syntenic blocks shared between the species. A repetitive sequence is found in the D. pseudoobscura genome at many junctions between adjacent syntenic blocks. Analysis of this novel repetitive element family suggests that recombination between offset elements may have given rise to many paracentric inversions, thereby contributing to the shuffling of gene order in the D. pseudoobscura lineage. Based on sequence similarity and synteny, 10,516 putative orthologs have been identified as a core gene set conserved over 25-55 million years (Myr) since the pseudoobscura/melanogaster divergence. Genes expressed in the testes had higher amino acid sequence divergence than the genome-wide average, consistent with the rapid evolution of sex-specific proteins. Cis-regulatory sequences are more conserved than random and nearby sequences between the species--but the difference is slight, suggesting that the evolution of cis-regulatory elements is flexible. Overall, a pattern of repeat-mediated chromosomal rearrangement, and high coadaptation of both male genes and cis-regulatory sequences emerges as important themes of genome divergence between these species of Drosophila.
Wafer thinning and back side processing to enable 3D stacking (2012)

We report on the several processes defined and executed for generating ultra thin 3D devices. The devices used have been processed on 200mm wafers using 130nm CMOS technology with TSVs. We focus on processes like wafer thinning, backside passivation, back side RDL (Re-Distribution Layer), front side and backside μbumping. We finally present the electrical characterization of manufactured 3D stacks executed in case of two-dies stacking and three-dies stacking. Functional chains of different lengths based on the number of TSVs-μbumps forming the chain (10, 30, and 252 TSVs-μbumps) were measured.

Abstract 19081: Renal Insufficiency as a Marker for Stroke Risk in Patients with Atrial Fibrillation (2010)

Background: Renal function is closely associated with cardiovascular disease. However, there are limited data about the relationship between renal function and stroke risk in patients with atrial fibrillation. Methods: Consecutive patients who underwent cardioversion for nonvalvular atrial fibrillation or flutter between January 2000 and December 2005 were studied. Clinical and laboratory data on risk factors, renal function, and a history of stroke was collected at the time of the cardioversion. Multivariate analysis for risk factors associated with a history of stroke was adjusted for age, gender, hypertension, diabetes, and CHF. Patients with normal glomerular filtration rate (GFR) > 60 mL/min were used as the comparison group. Results: A total of 1,424 patients, with a mean age 70 ± 12 years were identified. 140 (11.7%) had a history of stroke or transient ischemic attack (TIA). Patients with renal insufficiency, defined as GFR<60 mL/min, were older, more likely to have hypertension and CHF (p<0.001)....
Forward-looking objective functions (2002)

The effectiveness of traditional CAD optimization algorithms is proportional to the accuracy of the targeted objective functions. However, behavioral synthesis tools are not used in isolation; they form a strongly connected design flow where each tool optimizes its own objective function without considering the consequences on the optimization goals of the subsequently applied tools. Therefore, efforts to optimize one aspect of a design often have unforeseen negative impacts on other phases of the design process.
Human telomerase: biogenesis, trafficking, recruitment, and activation (2015)

Telomerase is the ribonucleoprotein enzyme that catalyzes the extension of telomeric DNA in eukaryotes. Recent work has begun to reveal key aspects of the assembly of the human telomerase complex, its intracellular trafficking involving Cajal bodies, and its recruitment to telomeres. Once telomerase has been recruited to the telomere, it appears to undergo a separate activation step, which may include an increase in its repeat addition processivity. This review covers human telomerase biogenesis, trafficking, and activation, comparing key aspects with the analogous events in other species.

IL-4-Induced Eosinophil Accumulation in Rat Skin Is Dependent on Endogenous TNF-α and α4 Integrin/VCAM-1 Adhesion Pathways (1998)

Abstract IL-4 has been implicated in the pathogenesis of a number of allergic inflammatory disease states where the accumulation of eosinophils is a prominant feature. The aim of the present study was to use an isotopic in vivo model to investigate the ability of recombinant rat IL-4 in inducing eosinophil accumulation in rat skin. 111In-eosinophil accumulation in response to intradermally injected IL-4 was measured during 0 to 4 h, 24 to 28 h, and 48 to 52 h. Accumulation was detected during the first two periods, but not at the later time point. The accumulation during 24 to 28 h, which was dose dependent, was investigated in detail. Administration i.v. of an anti-rat VCAM-1 mAb, but not an anti-rat ICAM-1 mAb, inhibited the accumulation of 111In-eosinophils induced by IL-4 (maximum inhibition, 80%). Further, when the 111In-eosinophils were pretreated in vitro with an anti-β2 integrin mAb, an anti-α4 integrin mAb, or a combination of both mAbs, before their injection into recipient rats, the IL-4-induced cell accumulation was inhibited by 63, 60, and 74%, respectively. Finally, coadministration of IL-4 with the soluble TNF receptor (p55)-IgG fusion protein significantly reduced the 111In-eosinophil accumulation induced by the cytokine, and TNF-α was detected in IL-4-injected skin sites by both immunostaining and bioassay. Our results demonstrate that IL-4 is a potent inducer of eosinophil accumulation in vivo, the response being dependent on the endogenous generation of TNF-α, β2 integrins, and α4 integrin/VCAM-1 interactions.
Imaging the destruction of individual ultrasound contrast microbubbles with diagnostic ultrasound (2004)

Ultrasound imaging of ultrasound contrast agent fragmentation in a water bath was performed with the color Doppler mode of the HDI 5000 (Phillips Ultrasound). A highly diluted suspension of ultrasound contrast microbubbles (Optison®) was injected into the water bath such that individual microbubbles passed through the image plane every few seconds. Decorrelation of the signal, along with the appearance of multiple signals, suggests that single microbubble fragmentation was observed, with daughter bubbles being formed from the original microbubbles, depending on the applied acoustic pressure.
Model-Based Design for Embedded Systems (2018)

This chapter addresses reconfigurable heterogenous and homogeneous multicore system-on-chip (SoC) platforms for streaming digital signal processing applications, also called DSP applications. In streaming DSP applications, computations can be specified as a data flow graph with streams of data items (the edges) flowing between computation kernels (the nodes). Most signal processing applications can be naturally expressed in this modeling style. Typical examples of streaming DSP applications are wireless baseband processing, multimedia processing, medical image processing, sensor processing (e.g., for remote surveillance cameras), and phased array radars. In a heterogeneous multicore architecture, a core can either be a bitlevel reconfigurable unit (e.g., FPGA), a word-level reconfigurable unit, or a general-purpose programmable unit (digital signal processor (DSP) or general purpose processor (GPP)). We assume the cores of the SoC are interconnected by a reconfigurable network-on-chip (NoC). The programmability of the individual cores enables the system to be targeted at multiple application domains. We take a holistic approach, which means that all aspects of systems design need to be addressed simultaneously in a systematic way. This is key for an efficient overall solution, because an interesting optimization in a small corner of the design might lead to inefficiencies in the overall design. We introduce streaming applications and multi-core architectures We present key design criteria for streaming applications and give a multi-dimensional classification of architectures for streaming applications. For each category one or more sample architectures are presented.
Novel Immunocytokine IL12-SS1 (Fv) Inhibits Mesothelioma Tumor Growth in Nude Mice (2013)

Mesothelin is a glycosylphosphatidylinositol-anchored glycoprotein that is highly expressed on the cell surface of malignant mesothelioma. Monoclonal antibodies against mesothelin are being evaluated for the treatment of mesothelioma. Immunocytokines represent a novel class of armed antibodies. To provide an alternative approach to current mesothelin-targeted antibody therapies, we have developed a novel immunocytokine based on interleukin-12 (IL12) and the SS1 Fv specific for mesothelin. IL12 possesses potent anti-tumor activity in a wide variety of solid tumors. The newly-developed recombinant immunocytokine, IL12-SS1 (Fv), was produced in insect cells using a baculovirus-insect cell expression system. The SS1 single-chain Fv was fused to the C terminus of the p35 subunit of IL12 through a short linker (GSADGG). The single-chain IL12-SS1 (Fv) immunocytokine bound native mesothelin proteins on malignant mesothelioma (NCI-H226) and ovarian (OVCAR-3) cells as well as recombinant mesothelin on A431/H9 cells. The immunocytokine retained sufficient bioactivity of IL12 and significantly inhibited human malignant mesothelioma (NCI-H226) grown in the peritoneal cavity of nude mice and showed comparable anti-tumor activity to that of the SS1P immunotoxin. IL12-SS1 (Fv) is the first reported immunocytokine to mesothelin-positive tumors and may be an attractive addition to mesothelin-targeted cancer therapies.
Interaction of Enteropathogenic and Shiga Toxin-Producing Escherichia coli and Porcine Intestinal Mucosa: Role of Intimin and Tir in Adherence (2005)

The ileal in vitro organ culture (IVOC) model using tissues originating from colostrum-deprived newborn piglets has proven to be an effective way to study the attaching and effacing (A/E) phenotype of porcine enteropathogenic Escherichia coli (EPEC) ex vivo. The aim of this study was to investigate the role of intimin subtype and Tir in the adherence of EPEC and Shiga-toxin-producing E. coli (STEC), isolated from different animal species, to porcine intestinal IVOC. Moreover, the role of intimin in Tir-independent adherence of the human EPEC strain E2348/69 was investigated using intimin and Tir-deficient derivatives. Our results demonstrated that A/E E. coli strains (AEEC) from various animal species and humans induce the A/E phenotype in porcine ileal IVOC and that intimin subtype influences intestinal adherence and tropism of AEEC strains. We also showed that a tir mutant of EPEC strain E2348/69 demonstrates close adherence to the epithelial cells of porcine ileal IVOC segments, with microvillous effacement but with no evidence of actin polymerization or pedestal formation, and that intimin seems to be involved in this phenotype. Overall, this study provides further evidence for the existence of one or more host-cell-encoded intimin receptor(s) in the pig gut.
High resolution velocity estimation for all digital, AC servo drives (2003)

Because the position transducers commonly used (optical encoders and electromagnetic resolvers) do not inherently produce a true, instantaneous velocity measurement, some signal processing techniques are generally used to estimate the velocity at each sample instant. This estimated signal is then used as the velocity feedback signal for the velocity loop control. An analysis is presented of the limitations of such approaches, and a technique which optimally estimates the velocity at each sample instant is presented. The method is shown to offer a significant improvement in command-driven systems and to reduce the effect of quantized angular resolution which limits the ultimate performance of all digital servo drives. The noise reduction is especially relevant for AC servo drives due to the high current loop bandwidths required for their correct operation. The method demonstrates improved measurement performance over a classical DC tachometer.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Variability in Cadence During Forced Cycling Predicts Motor Improvement in Individuals With Parkinson's Disease (2012)

Variability in severity and progression of Parkinson's disease symptoms makes it challenging to design therapy interventions that provide maximal benefit. Previous studies showed that forced cycling, at greater pedaling rates, results in greater improvements in motor function than voluntary cycling. The precise mechanism for differences in function following exercise is unknown. We examined the complexity of biomechanical and physiological features of forced and voluntary cycling and correlated these features to improvements in motor function as measured by the Unified Parkinson's Disease Rating Scale (UPDRS). Heart rate, cadence, and power were analyzed using entropy signal processing techniques. Pattern variability in heart rate and power were greater in the voluntary group when compared to forced group. In contrast, variability in cadence was higher during forced cycling. UPDRS Motor III scores predicted from the pattern variability data were highly correlated to measured scores in the forced group. This study shows how time series analysis methods of biomechanical and physiological parameters of exercise can be used to predict improvements in motor function. This knowledge will be important in the development of optimal exercise-based rehabilitation programs for Parkinson's disease.
