Surface Sensitivity of Electron Energy Loss Spectroscopy and Secondary-Ion Mass Spectrometry of Organic Films (1994)

Electron energy loss spectroscopy (EELS) and secondary-ion mass spectrometry (SIMS) are particularly useful for the study of surfaces because they give information about a very shallow depth (of order nm) of the sample. Precisely what these depths are in organic solids has been difficult to measure because the surface needs to be highly regular. We used Langmuir-Blodgett layers on silicon wafers. The films proved to be well packed and smooth. The chemical nature of the films was arranged to place "markers" at specific depths, which aided in the analysis of the data. We derive remarkably small information depths: less than 0.4 nm for EELS and 2 nm for SIMS.
Waste to liquid fuels: potency, progress and challenges (2015)

The valorization of municipal solid waste (MSW) into liquid fuels is a multi-beneficial global option for ensuring environmental and energy sustainability. The paper critically reviewed a wide range of recent literature on the potency, progress, and challenges associated with MSW upgrading into liquid fuels. Concise details on the various upgrading technologies involved such as gasification, pyrolysis, and syngas-to-fuels (i.e., syngas to gasoline and diesel) via a Fischer–Tropsch process were documented. Emphasis was critically given to the recent literature updates. The paper explored the role of heterogeneous catalyst systems in achieving the various processes with special considerations for optimizing fuel yield. Prospective technologies such as plasma gasification and nanoscale catalyst design with potentials to revolutionize the industry were also discussed. Copyright © 2015 John Wiley & Sons, Ltd.
Usage of Air Monitoring and Biomarkers of Isocyanate Exposure to Assess the Effect of a Control Intervention (2008)

Exposure to isocyanates is known to have respiratory effects in workers and therefore it is essential to monitor the occupational exposure. An earlier study of a continuous foaming plant using toluene diisocyanate (TDI) showed that the exposure to isocyanates can be high. Since then several preventive actions were implemented at the plant. The aim of this study was to observe the effect of these actions measured by air and biological monitoring. Four workers were monitored in the year 2000 and six in 2005, with air measurements during the continuous foaming process, and with measurements of biomarkers in one plasma sample each year and with two urinary samples being collected in the year 2000 and one in 2005. The median TDI air concentrations in 2005 were approximately 20% of the 2000 levels and the median levels of biomarkers in 2005 were approximately 10% of the 2000 levels. According to our measurements the preventive action had a real effect to decrease the exposure to TDI. As the workers both before and after the preventive actions used personal protective equipment, the use of biomarkers was necessary to assess the real gain in the preventive actions.
Ki‐ras activation and expression in transformed mouse lung cell lines (1990)

The Ki-ras proto-oncogene is activated by specific point mutations and is the transforming gene often identified in rodent and human lung tumors. An in vitro model to aid in the study of the consequences of Ki-ras activation and expression in mouse lung is needed. Accordingly, we have examined cell lines derived from chemically induced mouse lung tumors as well as spontaneous transformants of untreated mouse lung epithelial cells. The specific Ki-ras-activating gene mutations and the level of mRNA expression were examined for each cell line. Polymerase chain reaction and oligonucleotide hybridization were used to demonstrate that five of seven transformed lung cell lines contain codon 61 Ki-ras-activating mutations, resulting in an arginine substitution for wild-type glutamine. One transformed line contained this activating mutation and had also lost, or contained an altered, wild-type codon 61 Ki-ras allele. No codon 12 Ki-ras mutations were observed. Two transformed and two nontransformed epithelial lung cell lines contained only the wild-type codon 12 and 61 Ki-ras alleles. Northern blot analysis demonstrated that the Ki-ras mRNA was present in all the cell lines and was overexpressed in some, but not all, of the transformed lung cell lines. Those transformed lines with the highest levels of Ki-ras mRNA also expressed more H4-histone mRNA, suggesting that these cells have a greater proliferation rate. The level of Ki-ras mRNA increased during the proliferation of the nontransformed lung cells but then decreased upon reaching confluency. In contrast, the level of Ki-ras mRNA in the transformed lung cells was high during both growth and confluency, suggesting a potential defect in the regulation of Ki-ras in these cells. These lung cell lines will help provide a better understanding of the regulation of both the Ki-ras proto-oncogene and oncogene in the lung.

Arbitrary Viewpoint Video Synthesis From Multiple Uncalibrated Cameras (2004)

We propose a method for arbitrary view synthesis from uncalibrated multiple camera system, targeting large spaces such as soccer stadiums. In Projective Grid Space (PGS), which is a three-dimensional space defined by epipolar geometry between two basis cameras in the camera system, we reconstruct three-dimensional shape models from silhouette images. Using the three-dimensional shape models reconstructed in the PGS, we obtain a dense map of the point correspondence between reference images. The obtained correspondence can synthesize the image of arbitrary view between the reference images. We also propose a method for merging the synthesized images with the virtual background scene in the PGS. We apply the proposed methods to image sequences taken by a multiple camera system, which installed in a large concert hall. The synthesized image sequences of virtual camera have enough quality to demonstrate effectiveness of the proposed method.
A Capacitorless LDO Regulator With Fast Feedback Technique and Low-Quiescent Current Error Amplifier (2013)

This brief presents an ultralow quiescent class-AB error amplifier (ERR AMP) of low dropout (LDO) and a slew-rate (SR) enhancement circuit to minimize compensation capacitance and speed up transient response designed in the 0.11-μm 1-poly 6-metal CMOS process. In order to increase the current capability with a low standby quiescent current under large-signal operation, the proposed scheme has a class-AB-operation operational transconductance amplifier (OTA) that acts as an ERR AMP. As a result, the new OTA achieved a higher dc gain and faster settling time than conventional OTAs, demonstrating a dc gain improvement of 15.8 dB and a settling time six times faster than that of a conventional OTA. The proposed additional SR enhancement circuit improved the response based on voltage-spike detection when the voltage dramatically changed at the output node.
Fabrication of Atomically Precise Nanopores in Hexagonal Boron Nitride (2017)

We demonstrate the fabrication of individual nanopores in hexagonal boron nitride (hBN) with atomically precise control of the pore size. Previous methods of pore production in other 2D materials create pores of irregular geometry with imprecise diameters. By taking advantage of the preferential growth of boron vacancies in hBN under electron beam irradiation, we are able to observe the pore growth via transmission electron microscopy, and terminate the process when the pore has reached its desired size. Careful control of beam conditions allows us to nucleate and grow individual triangular and hexagonal pores with diameters ranging from subnanometer to 6nm over a large area of suspended hBN using a conventional TEM. These nanopores could find application in molecular sensing, DNA sequencing, water desalination, and molecular separation. Furthermore, the chemical edge-groups along the hBN pores can be made entirely nitrogen terminated or faceted with boron-terminated edges, opening avenues for tailored functionalization and extending the applications of these hBN nanopores.

Alternative anti-CD20 antibody versus desensitization for lymphoma patients with drug hypersensitivity reactions requiring discontinuation of rituximab, obinutuzumab, or ofatumumab. (2020)

8062 Background: Immunotherapy with anti CD20 is often associated with mild easily manageable infusion reactions. In rare cases, patients experience severe drug hypersensitivity reactions (DHR) serum sickness or anaphylaxis. These in turn may lead to discontinuation of the drug. In our experience, switching to a different anti-CD20 agent is a feasible alternative to discontinuation or desensitization protocols. Methods: From our pharmacology database we identified all the patients that received rituximab and/or obinutuzumab, and/or ofatumumab, and/or all the patients who received a flat dose of less than 50 mL of the same drugs and were followed at our institution. From the medical record, we identified all the cases where the anti-CD20 antibody was changed due to allergy, serum sickness or other types of DHR, and all those who received minimal doses of anti-CD20 in the context of a desensitization protocol. DHRs were evaluated either by an allergist, or by retrospective review following the World Allergy Organization guidelines. Our primary comparison, was to assess the proportion of pts able to completed planned infusion of abs using either approach (Fisher’s exact Test). Results: Among 343 patients receiving at least two different anti-CD20 antibodies or a flat dose of &lt; 50 mL, we identified 44 patients experiencing severe DHRs needing intervention. At the time of the reaction, 16 (36%) received the anti-CD20 as single agent, 24 (54%) in combination with chemotherapy, 4 (9%) in combination with ibrutinib or lenalidomide. In 9 (20%) patients the reaction was defined as anaphylactoid (8 rituximab; 1 obinutuzumab) and in 8 (18%) patients, all receiving rituximab, as serum sickness. Episodes of DHR were addressed with either desensitization (n = 29) or change of anti-CD20 agent (n = 25), 9 patients received both of these approaches, one patient switched anti-CD20 antibodies twice. Overall, 21 desensitizations were successful (72.4%), 8 failed; 23 changes of anti-CD20 were successful (92%) and 2 failed (p = 0.09). Conclusions: In patients with DHR use of an alternative anti-CD20 antibody is safe and is an alternative or complementary approach to anti-CD20 desensitization.

Palladium-catalysed heteroannulation with terminal alkynes: synthesis of phthalides 1 (1998)

The palladium–copper-catalysed heteroannulation of o-iodobenzoic acid 3 with terminal alkynes 4–18 leads to the synthesis of (Z)-3-alkylidenephthalides 19–33 as the major products. In certain cases, the formation of isocoumarins 34–37 is also observed.
Evaluating Strength and Stiffness of Unreinforced Masonry Infill Structures (2002)

Abstract : Masonry has been used for hundreds of years around the world in construction projects ranging from simple roadways to complex arch designs. Masonry is also commonly used in frame building structures as infill to either protect the inside of the structure from the environment or to divide inside spaces. During the design and analysis of steel/reinforced concrete frame structures, infill has commonly been ignored. Contrary to common practice, masonry infills do influence the overall behavior of structures when subjected to lateral forces. The influence of infills on overall behavior of the structure has been found to change with the direction in which the load is applied. This report gives guidelines on evaluating the lateral load capacity of infilled panels for in-plane and out-of-plane loading. Further guidelines account for the effect of out-of-plane loading on in-plane capacity. This report is a complement to applicable provisions in FEMA 310 with respect to seismic evaluation of buildings. These guidelines should prove useful for engineering evaluations of the lateral strength of buildings with respect to wind or earthquake forces. The guidelines give the engineer a strength-based alternative to FEMA 273 a performance-based method, which should also result in safe and economical construction.
Determining the fundamental matrix with planes: instability and new algorithms (2002)

The fundamental matrix is a key concept when working with uncalibrated images and multiple viewpoints. It contains all the available geometric information and enables recovery of the epipolar geometry from uncalibrated perspective views. The problem of its determination from points which lie in several planes is discussed. In that case, there is an homography between coordinates of points in the two images. The use of different criteria to compute the homography is investigated. A very simple and important relation between the homography matrices obtained from the observation of planar surfaces and the fundamental matrix is then established. Using simulations and real images to validate this analysis, it is shown that as a first consequence of this relation, the general methods to compute the fundamental matrix are unstable when the points lie close to planes. New algorithms are proposed to exploit this situation through the use of the previous relation. Their performance is compared to the performance of the general algorithm using a large number of noisy synthetic data and real images.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Introduction of Vigilante Players in Cognitive Networks with Moving Greedy Players (2015)

We propose adding a vigilante player and using non-traditional game strategy for decision making to improve the performance of a cognitive radio network. To date, the application to cognitive radio networks of a hybrid player such as a vigilante, which is both cooperative and non- cooperative, has not been significantly studied. We use a novel play strategy (i.e., altruism) to police a wireless network. Using this new player, we present and test a series of predictive algorithms that show an improvement in wireless channel utilization over traditional collision- detection algorithms. Our results demonstrate the viability of using this novel strategy to inform and create more efficient cognitive radio networks.
Locally Refinable Splines over Box-Partitions (2012)

We address progressive local refinement of splines defined on axes parallel box-partitions and corresponding box-meshes in any space dimension. The refinement is specified by a sequence of mesh-rectangles (axes parallel hyperrectangles) in the mesh defining the spline spaces. In the 2-variate case a mesh-rectangle is a knotline segment. When starting from a tensor-mesh this refinement process builds what we denote an LR-mesh, a special instance of a box-mesh. On the LR-mesh we obtain a collection of hierarchically scaled B-splines, denoted LR B-splines, that forms a nonnegative partition of unity and spans the complete piecewise polynomial space on the mesh when the mesh construction follows certain simple rules. The dimensionality of the spline space can be determined using recent dimension formulas. Oppdragsgiver: SINTEF ; Research Council of Norway
Underdetermined DOA estimation in the presence of mutual coupling for sparse circular array (2017)

In this paper, we present a simplified mutual coupling matrix (MCM) for Sparse Circular Arrays (SCA) that is used for underdetermined direction of arrival (DOA) estimation. The array type used in this paper is composed of dense and sparse parts that obtains very low mutual coupling (MC). This leads to a banded-like MCM. By incorporating the MCM in the DOA estimation problem, SCA is capable of DOA estimation for more source than sensors. Simulation results shows that we obtain better performance.
Electronic health record alerts enhance mass screening for chronic hepatitis B (2020)

To measure the effect of an electronic health record (EHR) alert on chronic hepatitis B (CHB) screening among at-risk Asian and Pacific Islanders (API). API patients who had not yet completed hepatitis B surface antigen (HBsAg) testing were identified by a novel EHR-based population health tool. At-risk API patients in Cohort 1 (primarily privately insured) and Cohort 2 (includes Medicare and/or Medicaid) were randomized to alert activation in their electronic medical charts or not. In total, 8299 API were found to be deficient in HBsAg completion at baseline within our health system. In Cohort 1, 1542 patients and 1568 patients were randomized to the alert and control respectively. In Cohort 2, 2599 patients and 2590 patients were randomized to the alert and control respectively. For both cohorts combined, 389 HBsAg tests were completed in the alert group compared to 177 HBsAg tests in the control group (p < 0.0001; OR = 2.3; 95% CI 1.94-2.80), but there was no increased detection of HBsAg positivity from the alert (15 versus 13 respectively, p = 0.09; OR = 0.5; 95% CI 0.24-1.09). Our results demonstrate that personalized, automated electronic alerts increase screening for CHB, but more comprehensive measures are needed to detect HBsAg positive patients.NIH Trial Registry Number: NCT04240678.
Sound generation and control of thermoacoustic instabilities by nanosecond plasma discharges (2016)

Sound generation by nanosecond repetitively pulsed plasma discharges is investigated experimentally. High voltage pulses of 10 nanosecond duration provide rapid heating of the air. A high-frequency pulse train between 20 and 30 kHz is burst modulated to generate low-frequency components. The generation of pressure waves from the modulated discharge pulse train is characterized based on acoustic measurements in an impedance tube. Different combinations of modulation frequency, electrode gap distance, modulation duty cycle and pulse repetition frequency are studied in terms of electric energy and acoustic source amplitude. The measurement results suggest that overall, the amplitude of the pressure wave components at the modulation frequency can be well estimated based on the electrical power using an analytical expression for acoustically compact unsteady heating. As an application of sound generation by low-frequency modulated NRP discharges, feedback control is applied to suppress thermoacoustic instabilities in a Rijke tube. The pressure oscillation amplitude is reduced by more than two orders of magnitude when the plasma discharges are suitably synchronized with the self-excited fluctuations.
The DLR bimanual haptic device with optimized workspace (2011)

Abstract-This article accompanies a video that presents a bimanual haptic device composed of two DLR/KUKA Light weight Robot (LWR) arms. The LWRs have similar dimensions to human arms, and can be operated in torque and position control mode at an update rate of 1kHz. The two robots are mounted behind the user, such that the intersecting workspace of the robots and the human arms becomes maximal. In order to enhance user interaction, various hand interfaces and additional tactile feedback devices can be used together with the robots. The presented system is equipped with a thorough safety architecture that assures safe operation for human and robot. Additionally, sophisticated control strategies improve performance and guarantee stability. The introduced haptic system is well suited for versatile applications in remote and virtual environments, especially for large unsealed movements.
C17orf37 regulates prostate cancer cell migration and invasion by NF‐kB mediated downstream target genes (2008)

C17orf37/MGC14832 is located in the hot spot locus of human chromosomal region 17q12‐21 next to ErbB2. Earlier we have characterized C17orf37 protein, and have shown the protein expression significantly higher in prostate cancer cells and tissue specimens compared to normal prostate cells. By gene knock down studies, we have found C17orf37 regulates prostate cancer cell migration and invasion by modulating certain key proteins involved in the process like MMP‐9, uPA and VEGF. Here we hypothesize that C17orf37 acts as a membrane bound signaling molecule and facilitates migration and invasion of prostate cancer cells by NF‐kB mediated downstream target genes. Our results show that knockdown of C17orf37 in DU‐145 prostate cancer cells by increasing concentration of gene specific siRNA significantly reduced the DNA binding activity of NF‐kB in a dose dependent manner. Furthermore, C17orf37 knockdown also decreased the activated phosphorylated Akt to inactive form suggesting C17orf37 must be located upstream of Akt. Imaging DU‐145 and LNCaP prostate cancer cells by total internal reflection fluorescence microscopy we have observed C17orf37 on the membrane of these cells and this observation is supported by the fact that C17orf37 has a potential prenylation motif. By Fluorescence Lifetime Imaging Microscopy based FRET assys we have located the C17orf37 interacts with annexin A2 mostly in the membrane and perinuclear region. Currently we are investigating the functional significance of C17orf37 and annexin A2 interaction and the downstream signaling cascade that regulates migration and invasion in prostate cancer cells.

On the Transmitted Power in Generalized Partial Response (1976)

The advantages with regard to noise enhancement of certain suboptimum nonlinear techniques for "equalization" of linear distortion on channels used for digital data transmission have recently received considerable attention. These nonlinear schemes fall into two classes: decision feedback and nonlinear precoding. Yet each of these methods has an associated peculiarity which has impeded attempts to give firm bounds on performance. Thus, for decision feedback error propagation has caused the analytical pains, while for nonlinear precoding of an <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</tex> -level alphabet the unknown increase in transmitter power has been culpable. The former problem has recently received successful attention by one of the present authors and some colleagues. Here we address the concomitant problem for nonlinear precoding and its extension to quadrature amplitude modulation (QAM) and show that the transmitted normalized power <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">P</tex> satisfies <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(L^{2} - 1)/3 \leq P \leq (L^{2} - 1)/3 + 1</tex> .
