Quantifying repetitive hand activity for epidemiological research on musculoskeletal disorders – Part II: comparison of different methods of measuring force level and repetitiveness (2006)

This paper focuses on comparisons between the different methods of assessing repetitive hand activities. Various methods were used to measure hand force and repetitiveness of hand activities on 733 subjects in the study described by Bao et al. (2006). Two definitions of repetitiveness were used in analysis of detailed time studies of repetitive hand activities and four parameters of the American Conference of Governmental Industrial Hygienists (ACGIH) hand activity level (HAL) and the Strain Index methods were estimated by ergonomists and used to quantify repetitiveness. Hand forces were measured or estimated using three different methods: 1) measured with a force gauge or mimicked on a force gauge (force matching); 2) estimated by ergonomists using rating scales; 3) self-reports by subjects. The jobs were also evaluated using the ACGIH HAL and Strain Index methods when different repetitiveness quantification methods were used. Results showed that different definitions of repetitive exertion might lead to measuring different physical exposure phenomena and produce very different results. There were poor correlations between the measures of repetitiveness estimated by the different methods. Correlations between force quantifications using different methods were also poor. This suggests that parameters measured by different methods might not be interchangeable. Both the ACGIH HAL and Strain Index methods identified more 'hazardous' jobs when repetitiveness was estimated by ergonomists than when it was calculated by detailed time studies of forceful hand exertions. The Strain Index method identified more 'hazardous' jobs than the ACGIH HAL method. Overall, the between-methods agreements were found to be moderate to substantial.
ISOIMMUNIZATION IN PREGNANCY (1941)

A number of transfusion accidents in pregnancy have been reported in the literature, even though the donor, frequently the husband, was in the same blood group as the patient.<sup>1</sup>In one instance analyzed by Levine and Stetson<sup>2</sup>it was assumed that the accident could be attributed to an agglutinin resulting from immunization of the mother by factors in the fetus inherited from the father. Analysis of a series of 12 cases in which atypical agglutinins could be demonstrated revealed the significant fact that these patients presented obstetric histories characterized by a number of complications such as toxemia, macerated fetus, repeated abortions, miscarriages or stillbirths.<sup>3</sup> Recently 5 additional patients with atypical agglutinins were observed, 3 of whom gave birth to infants suffering from erythroblastosis foetalis. The obstetric histories of these cases are so striking as to merit brief mention. One patient, J. L. (decigravida, sextipara), now pregnant and

Classifying urban landscape in aerial LiDAR using 3D shape analysis (2009)

The classification of urban landscape in aerial lidar point clouds is useful in 3D modeling and object recognition applications in urban environments. In this paper, we introduce a multi-category classification system for identifying water, ground, roof, and trees in airborne lidar. The system is organized as a cascade of binary classifiers, each of which performs unsupervised region growing followed by supervised, segment-wise classification. Categories with the most discriminating features, such as water and ground, are identified first and are used as context for identifying more complex categories, such as trees. We use 3D shape analysis and region growing to identify ¿planar¿ and ¿scatter¿ regions that likely correspond to ground/roof and trees respectively. We demonstrate results on two urban datasets, the larger of which contains 200 million lidar returns over 7km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . We show that our ground, roof, and tree classifiers, when trained on one dataset, perform well on the other dataset.
Distribution of Centromere-Like<i>parS</i>Sites in Bacteria: Insights from Comparative Genomics (2007)

Partitioning of low-copy-number plasmids to daughter cells often depends on ParA and ParB proteins acting on centromere-like parS sites. Similar chromosome-encoded par loci likely also contribute to chromosome segregation. Here, we used bioinformatic approaches to search for chromosomal parS sites in 400 prokaryotic genomes. Although the consensus sequence matrix used to search for parS sites was derived from two gram-positive species, putative parS sites were identified on the chromosomes of 69% of strains from all branches of bacteria. Strains that were not found to contain parS sites clustered among relatively few branches of the prokaryotic evolutionary tree. In the vast majority of cases, parS sites were identified in origin-proximal regions of chromosomes. The widespread conservation of parS sites across diverse bacteria suggests that par loci evolved very early in the evolution of bacterial chromosomes and that the absence of parS, parA, and/or parB in certain strains likely reflects the loss of one of more of these loci much later in evolution. Moreover, the highly conserved origin-proximal position of parS suggests par loci are primarily devoted to regulating processes that involve the origin region of bacterial chromosomes. In species containing multiple chromosomes, the parS sites found on secondary chromosomes diverge significantly from those found on their primary chromosomes, suggesting that chromosome segregation of multipartite genomes requires distinct replicon-specific par loci. Furthermore, parS sites on secondary chromosomes are not well conserved among different species, suggesting that the evolutionary histories of secondary chromosomes are more diverse than those of primary chromosomes.
Motion invariance and custom blur from lens motion (2011)

We demonstrate that image stabilizing hardware included in many camera lenses can be used to implement motion invariance and custom blur effects. Motion invariance is intended to capture images where objects within a range of velocities appear defocused with the same point spread function, obviating the need for blur estimation in advance of de-blurring. We show that the necessary parabolic motion can be implemented with stabilizing lens motion, but that the range of velocities to which capture is invariant decreases with increasing exposure time. We also show that, when that range is expanded through increased lens displacement, lens motion becomes less repeatable. In addition to motion invariance, we demonstrate that stabilizing lens motion can be used to design custom defocus kernels for aesthetic purposes, and can replace lens accessories.
Implementation of the near-field signal redundancy phase-aberration correction algorithm on two-dimensional arrays (2007)

Near-field signal-redundancy (NFSR) algorithms for phase-aberration correction have been proposed and experimentally tested for linear and phased one-dimensional arrays. In this paper the performance of an all-row-plus-two-column, two-dimensional algorithm has been analyzed and tested with simulated data sets. This algorithm applies the NFSR algorithm for one-dimensional arrays to all the rows as well as the first and last columns of the array. The results from the two column measurements are used to derive a linear term for each row measurement result. These linear terms then are incorporated into the row results to obtain a two-dimensional phase aberration profile. The ambiguity phase aberration profile, which is the difference between the true and the derived phase aberration profiles, of this algorithm is not linear. Two methods, a trial-and-error method and a diagonal-measurement method, are proposed to linearize the ambiguity profile. The performance of these algorithms is analyzed and tested with simulated data sets.
Microwave electromechanical resonator consisting of clamped carbon nanotubes in an abacus arrangement (2007)

We describe nanoscale electromechanical resonators capable of operating in ambient-pressure air at room temperature with unprecedented fundamental resonance frequency of $\ensuremath{\sim}4\phantom{\rule{0.3em}{0ex}}\mathrm{GHz}$. The devices are created from suspended carbon nanotubes loaded abacus style with inertial metal clamps, yielding short effective beam lengths. We examine the energy dissipation in the system due to air damping and contact loss. Such nanoabacus resonators open windows for immediate practical microwave frequency nanoelectromechanical system applications.
End-node-based congestion-aware network load balancing (2004)

Streaming services and visual communication services delivered over the Internet have become popular in recent years. In the future, broadband services using MPEG2/4 will become the dominant type. These services require transport protocols that provide high quality and high throughput from end to end of the system. We propose a new transfer method that allows the network load to be adaptively balanced according to the network's state. We also estimated the effectiveness of the proposed scheme by computer simulation.
Adaptive sampling in three dimensions for volume rendering on GPUs (2007)

Direct volume rendering of large volumetric data sets on programmable graphics hardware is often limited by the amount of available graphics memory and the bandwidth from main memory to graphics memory. Therefore, several approaches to volume rendering from compact representations of volumetric data have been published that avoid most of the data transfer between main memory and the graphics programming unit (GPU) at the cost of additional data decompression by the GPU. To reduce this performance cost, adaptive sampling techniques were proposed; which are, however, usually restricted to the sampling in view direction. In this work, we present a GPU-based volume rendering algorithm with adaptive sampling in all three spatial directions; i.e., not only in view direction but also in the two perpendicular directions of the image plane. This approach allows us to reduce the number of samples dramatically without compromising image quality; thus, it is particularly well suited for many compressed representations of volumetric data that require a computational expensive GPU-based sampling of data.
DNA Testing, Banking, and Genetic Privacy (2006)

"Who am I?” has always been a fundamental philosophical question that may require decades of reflection to answer. With the advent of DNA analysis, there is a growing public impression that the answer may be found in our genes. Various Internet sites offer descriptions of our ancestral history on the basis of our DNA, as well as testing for specific “disease genes” or general profiles that are used to recommend lifestyle changes, such as foods to be eaten or avoided. Researchers have even suggested that although the scientific evidence is speculative and at best probabilistic, many people will want to have their DNA analyzed for markers of predispositions toward certain behaviors, including risk taking, overeating, aggression, and even criminality.
Charge transfer cross section of He+ in collisional helium plasma using the plasma immersion ion implantation technique (1993)

The charge transfer collision cross section of He+ ions in a collisional helium plasma has been determined based on the ion energy distribution at the target during the plasma immersion ion implantation (PIII) process. The ion energy distribution is obtained by inferring data from a secondary-ion mass spectroscopy measurement and a simple collisional theory. The value of the charge transfer cross section in the collisional plasma was found to be higher than previously published values. The cross-section value determined by the PIII technique was used in a plasma simulation and was found to agree with our experimental observations.
Effects of rapid thermal anneal on refractive index and hydrogen content of plasma-enhanced chemical vapor deposited silicon nitride films (1996)

The objective of this paper is to understand and quantify the effects of rapid thermal anneal (RTA) on refractive index, thickness, and hydrogen content of plasma-enhanced, chemical vapor-deposited (PECVD) silicon nitride films. It is shown that RTA is more effective than identical furnace anneal. A threshold in as-deposited refractive index value is found, above which the index of a silicon nitride film increases, while the thickness and bonded hydrogen content decreases as result of the RTA. In addition, the magnitude of increase in the index is proportional to the as-deposited index value. The threshold index value increases with the increase in silicon nitride deposition temperature. A direct correlation is found between the annealing-induced increase in refractive index and the corresponding decrease in total bonded hydrogen concentration in the PECVD silicon nitride films. Finally, it is shown that the release of bonded hydrogen from the film can passivate defects in the underlying silicon substrate and increase the performance of silicon devices such as solar cells.

Scan-free direct measurement of an extremely high-dimensional photonic state (2015)

Retrieving the vast amount of information carried by a photon is an enduring challenge in quantum metrology science and quantum photonics research. The transverse spatial state of a photon is a convenient high-dimensional quantum system for study, as it has a well-understood classical analog as the transverse complex field profile of an optical beam. One severe drawback of all currently available quantum metrology techniques is the need for a time-consuming characterization process, which scales very unfavorably with the dimensionality of the quantum system. Here we demonstrate a technique that directly measures a million-dimensional photonic spatial state with a single setting of the measurement apparatus. Through the arrangement of a weak measurement of momentum and parallel strong measurements of position, the complex values of the entire photon state vector become measurable directly. The dimension of our measured state is approximately four orders of magnitude larger than previously measured. Our work opens up a practical route for characterizing high-dimensional quantum systems in real time. Furthermore, our demonstration also serves as a high-speed, extremely high-resolution unambiguous complex field measurement technique for diverse classical applications.

Effects of learning on cytochrome oxidase activity in cuttlefish brain (2001)

Using cytochrome oxidase (CO) histochemistry, the effects of instrumental conditioning in cuttlefish central nervous system were examined. The posterior superior frontal lobe showed an increase of CO labelling just after training, whereas the anterior superior frontal lobe exhibited a decrease of CO staining 24 h post-training. These findings provide the first metabolic evidence for the involvement of the superior frontal lobe in learning and memory processes in cuttlefish. It is concluded that CO histochemistry can be used to provide a functional mapping of learning-induced plasticity in cuttlefish brain.

Recent Clinical Experience with the Grid in the X-Ray Treatment of Advanced Cancer (1952)

When all sites and types of cancer are included, the cure rate from currently accepted methods of treatment does not exceed 25 per cent. This means that about 75 per cent of all cancer victims must be considered incurable and can be treated only palliatively for prolongation of useful life or relief of symptoms, or both. The value of radiotherapy as a palliative agent is not universally appreciated. There is often a lack of interest in the hopeless or incurable patient and either no active treatment is given or only meaningless token therapy. Recently, renewed interest has been displayed in the use of grids for roentgen therapy of advanced cancers. Grids have been used in roentgen therapy since 1909, when Alban Köhler (1) made his first report. Later, in 1933, Liberson (2) suggested the use of a metallic lead grid and worked out the biological and physical aspects which are, for the most part, valid to this day. Others, including Haring (3), Grynkraut (4), and Jolles (5) have also suggested the use of grids, all to the same end, to improve the dose to the tumor without compromising normal tissues. Biophysicists have repeatedly indicated a greater normal tissue tolerance to ionizing radiation through small portals in experimental animals (6), and in the recent work with grids it has been shown that this increased tolerance may be obtained through the use of large aggregates of small portals separated by relatively opaque areas. The most recent clinical report on this subject in this country was made in June 1949, by Dr. Hirsch Marks, who read a paper on the use of a grid with roentgen therapy before the Radiological Section of the American Medical Association in Atlantic City. In February 1950, Marks presented some of his treated patients at the Mount Sinai Hospital, New York. Two features which impressed us at this time were the degree of palliation obtained and the tolerance of normal tissue for doses of x-ray in excess of any hitherto employed on human material. Marks substituted a lead-rubber grid for Liberson's metallic one and employed the same grid openings throughout the treatment. Furthermore, he increased the total dose far beyond that suggested by Liberson. Marks' (7) suggested dose in February 1950 was 24,000 r in air, in daily fractions, in a over-all period of twenty-eight days, through a grid in which the proportion of closed to open spaces was 40 to 60 per cent. More recently he has recommended a total dose of 10,000 r in air with a 20 × 20-cm. grid and 12,000 r in air with a 10 × 15-cm. grid. Loevinger (8), of our physics department, made measurements with the grid which have guided us in our use of this method up to the present. From February 1950 until Sept. 1, 1951, 149 patients with cancer proved by biopsy, and established as hopeless from the point of view of surgery or conventional radiotherapy, were treated by this method.
Nodal Impedance-Based Stability Analysis of Dc Nanogrids (2018)

With the growing interest in electrification and interfacing of clean energy and energy storage, new challenges are emerging in stability analysis and control of such systems. Existing stability analysis methods work well for systems with pre-defined power flow and fixed architecture, and most lead to design criteria for source and load impedances. However, the methods presented in the literature are not suitable for analyzing dynamically changing systems, especially for online stability evaluation and monitoring. The nodal impedance-based stability analysis method presented in this paper extends the boundaries of the existing criteria and leads to a practical and effective solution for online stability evaluation and monitoring. Hardware results are provided to validate the proposed analysis method on a scaled-down nanogrid system.

Investigation of the Reaction between Ammonium Sulfide, Aldehydes, and α-Hydroxyketones or α-Dicarbonyls To Form Some Lipid−Maillard Interaction Products Found in Cooked Beef (1997)

Aqueous reaction mixtures containing α-dicarbonyls (2,3-butanedione or 2,3-pentanedione) or α-hydroxyketones (1-hydroxypropanone, 1-hydroxy-2-butanone, or 3-hydroxy-2-butanone), alkanals (C4−C10) and ammonium sulfide were heated at 140 °C for 30 min. Among the products formed were 3-thiazolines and thiazoles with C3−C9 alkyl substituents in the 2-position and methyl or ethyl in positions 4 and/or 5. Similar compounds have recently been reported in cooked beef, and their presence in the reaction mixtures confirmed the proposed route of formation, in cooked beef, from the reaction of lipid-derived aldehydes with dicarbonyls, ammonia, and hydrogen sulfide produced via the Maillard reaction. Trialkylpyridines, which had been observed in cooked beef, were also formed by the reaction of three molecules of aldehyde with one of ammonia. The mass spectra of all of these compounds are reported. Keywords: Flavor; Maillard reaction; lipids; 3-thiazolines; thiazoles; alkylpyridines
