Distributed shared memory in a loosely coupled distributed system (1988)

Implementation experiences with a distributed shared-memory system implemented in a loosely coupled distributed system are described. The goal was to investigate the feasibility of distributed shared memory (DSM) in an operating system kernel. The organization of the DSM described resembles a cross-processor segmented paging system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
[G-banding and high resolution chromosome study of a human lung adenocarcinoma cell line LGC-7910]. (1990)

G-banding and high resolution chromosome banding techniques were used in studying a human lung adenocarcinoma cell line LGC-7910. One hundred cells were counted at Passage 150. Ten, twelve and ten cells were analyzed at Passages 150, 173 and 183, respectively. The model number of chromosome in this cell line was 67-69. A number of marker chromosomes related to complex chromosomal rearrangement was observed. The analysis of chromosomes at the different passages showed a stability during subculture of the cell line. It was found that the cell line had partial deletion of the short arm on chromosome 7 (with breakpoint at 7p15.3-p13), rearrangement of the arm on chromosome 1 (with breakpoint at 1p13.1) and increase in chromosome 7 number. The results suggested that such chromosome alteration be related to the expression of activated oncogenes during carcinogenesis.
Implicit Numerical Solution for a Normal Shock. (1983)

Abstract : There are basically two techniques used to solve the Navier-Stokes equations for fluid flow. These techniques are implicit and explicit methods. Both methods along with characteristic boundary conditions for solving quasi-one-dimensional nozzle flow are presented. Two types of characteristic boundary conditions, those of Steger and McKenna, were tested for each scheme. Solutions of isentropic supersonic flow and flow with shocks were obtained for a diverging nozzle. The behavior of each boundary condition on both implicit and explicit schemes were the same. They deviated from the theoretical values by less than one percent. A test to determine the utility of each scheme was run by allowing the exit boundary conditions to change in the hope of forcing the shock to move upstream or downstream. The shock would not move in the implicit scheme for either boundary condition. The explicit scheme could move the shock, but only when Steger's boundary condition was used. (This is the one which specified only pressure.) (Author)

Analyzing the effects of free water modeling by deep learning on diffusion MRI structural connectivity estimates in glioma patients (2020)

Diffusion-weighted MRI makes it possible to quantify subvoxel brain microstructure and to reconstruct white matter fiber trajectories with which structural connectomes can be created. However, at the border between cerebrospinal fluid and white matter, or in the presence of edema, the obtained MRI signal originates from both the cerebrospinal fluid as well as from the white matter partial volume. Diffusion tractography can be strongly influenced by these free water partial volume effects. Thus, including a free water model can improve diffusion tractography in glioma patients. Here, we analyze how including a free water model influences structural connectivity estimates in healthy subjects as well as in brain tumor patients. During a clinical study, we acquired diffusion MRI data of 35 glioma patients and 28 age- and sex-matched controls, on which we applied an open-source deep learning based free water model. We performed deterministic as well as probabilistic tractography before and after free water modeling, and utilized the tractograms to create structural connectomes. Finally, we performed a quantitative analysis of the connectivity matrices. In our experiments, the number of tracked diffusion streamlines increased by 13% for high grade glioma patients, 9.25% for low grade glioma, and 7.65% for healthy controls. Intra-subject similarity of hemispheres increased significantly for the patient as well as for the control group, with larger effects observed in the patient group. Furthermore, inter-subject differences in connectivity between brain tumor patients and healthy subjects were reduced when including free water modeling. Our results indicate that free water modeling increases the similarity of connectivity matrices in brain tumor patients, while the observed effects are less pronounced in healthy subjects. As the similarity between brain tumor patients and healthy controls also increased, connectivity changes in brain tumor patients may have been overestimated in studies that did not perform free water modeling.
Processing of staphylococcus aureus and zymosan particles by human leukocytes measured by flow cytometry (1984)

Staphylococcus aureus were labeled with fluorescein-isothiocyanate (FITC), stained by ethidium bromide (EB), and measured by flow cytometry (FCM). Bacteria were identified by their FITC-fluorescence and discriminated from the leukocyte cell nuclei by the much higher EB fluorescence and lower coefficient of variation of the latter. Following phagocytosis, both the bacterial FITC- and EB-fluorescence decayed. The mean FITC-fluorescence was reduced about 20% after 15 min and 30-50% after 60 min. Zymosan particles were labeled by FITC and incubated with leukocytes for 15 min. Phagocytes were sorted by FCM and the zymosan particles were liberated by sonication. Their forward angle light scatter was reduced by about 50.6 +/- 2.1% and the FITC-fluorescence by 8.7 +/- 1.0% (mean +/- SD). The reduced FITC-fluorescence and light scatter suggests degradation of proteins, and the decay of EB-fluorescence degradation of DNA, but the specificity remains to be established. By this method phagocytes from a patient with systemic lupus erythematosus seemed to have a selective defect in DNA degradation, whereas phagocytes from a patient with acute myelogenous leukemia had a low capacity to degrade bacterial proteins. This technique offers opportunities for automatic measurements of bacteria and zymosan particle degradation by phagocytes.

Long-Term Effects of Feeding Monensin on Methane Production in Lactating Dairy Cows (2007)

The objective of this study was to determine the long-term effects of feeding monensin on methane (CH4) production in lactating dairy cows. Twenty-four lactating Holstein dairy cows (1.46 +/- 0.17 parity; 620 +/- 5.9 kg of live weight; 92.5 +/- 2.62 d in milk) housed in a tie-stall facility were used in the study. The study was conducted as paired comparisons in a completely randomized design with repeated measurements in a color-coded, double-blind experiment. The cows were paired by parity and days in milk and allocated to 1 of 2 treatments: 1) the regular milking cow total mixed ration (TMR) with a forage-to-concentrate ratio of 60:40 (control TMR; placebo premix) vs. a medicated TMR (monensin TMR; regular TMR + 24 mg of Rumensin Premix/kg of dry matter) fed ad libitum. The animals were fed and milked twice daily (feeding at 0830 and 1300 h; milking at 0500 and 1500 h) and CH4 production was measured prior to introducing the treatments and monthly thereafter for 6 mo using an open-circuit indirect calorimetry system. Monensin reduced CH4 production by 7% (expressed as grams per day) and by 9% (expressed as grams per kilogram of body weight), which were sustained for 6 mo (mean, 458.7 vs. 428.7 +/- 7.75 g/d and 0.738 vs. 0.675 +/- 0.0141, control vs. monensin, respectively). Monensin reduced milk fat percentage by 9% (3.90 vs. 3.53 +/- 0.098%, control vs. monensin, respectively) and reduced milk protein by 4% (3.37 vs. 3.23 +/- 0.031%, control vs. monensin, respectively). Monensin did not affect the dry matter intake or milk yield of the cows. These results suggest that medicating a 60:40 forage-to-concentrate TMR with 24 mg of Rumensin Premix/kg of dry matter is a viable strategy for reducing CH4 production in lactating Holstein dairy cows.
Automatic Centering Unit for the Registration of a Three-Tube Color Television Camera (1972)

Precise centering of the several images of a color television camera is difficult to maintain for long periods. A digital system is described which detects and corrects the centering errors from the video signals of normal scenes. In this system the video is converted to short pulses representing high-level, sharp edges of objects and the horizontal centering errors are then detected by comparing these pulses for relative time differences. Vertical errors are detected by a similar system which operates from line to line on signals recreated from the pulses by line-strobing. These signals contain vertical errors only. High-quality integrating stores are used to extract the average corrective powers from the error signals. The dc voltages thus obtained are then used to modify the appropriate centering control voltages.
Cloning, analysis, and overexpression of the gene encoding isobutylamine N-hydroxylase from the valanimycin producer, Streptomyces viridifaciens (1997)

The flavoprotein isobutylamine N-hydroxylase (IBAH) catalyzes the oxidation of isobutylamine to isobutylhydroxylamine, a key step in the biosynthesis of the azoxy antibiotic valanimycin. By using oligonucleotide primers designed from peptide sequence information derived from native IBAH, a fragment of the gene (vlmH) encoding IBAH was amplified by PCR from a genomic library of the valanimycin-producing organism, Streptomyces viridifaciens MG456-hF10. The gene fragment was then employed as a probe to clone the entire vlmH gene from an S. viridifaciens genomic library. Overexpression of the vlmH gene in Escherichia coli gave a soluble protein that was purified to homogeneity. The purified protein exhibited the catalytic activity expected for IBAH. The deduced amino acid sequence of IBAH exhibited the greatest similarity to the Sox/DszC protein from Rhodococcus sp. strain IGT38, a flavoprotein involved in the oxidation of dibenzothiophene to the corresponding sulfone. Significant similarities were also found between the amino acid sequence of IBAH and those of the acyl coenzyme A dehydrogenases.
Characterization of Thermal Hyperalgesia, c-fos Expression, and Alterations in Neuropeptides After Mechanical Irrigation of the Dorsal Root Ganglion (1995)

This experimental model reliably produced a disorder resembling an acute phase sciatica and should help further advance the understanding of pathomechanisms of spinal pain after irritation of the dorsal root ganglion in humans.
In vitro model of rapid intravenous fluid administration (2003)

Intravenous (IV) fluid delivery requires physical intrusion into the vein of a living subject which results in a complex interaction between the rigid artificial catheter and the compliant vein. To study this interaction and to determine the contribution of vein resistance to the overall flow rate of fluid delivery, a laboratory apparatus was built to simulate fluid delivery into an in vitro model of the brachial or cephalic vein. Experiments were conducted with different physical and physiological parameters in order to determine their role in rapid fluid administration. The results showed that central vein resistance or increased tissue pressure reduce infusion flow rate.
Improving the energy effectiveness of domestic refrigerators by the application of mixed refrigerants (1978)

A critical review of U.S. and foreign literature on the use of a mixture of refrigerants rather than a single one in a refrigeration unit indicates that energy can be conserved in properly arranged systems. An independent analytical study performed under the current contract using a 50% mixture of R-12 and R-114 in a two-evaporator refrigerator typical of domestic refrigerators showed an energy saving of 12%. The cycle explored was a non-optimized one, so greater energy savings are theoretically possible. The application of refrigerant mixtures to domestic refrigerators would not be a panacea, but would require a redesign of the refrigeration circuit and a resizing of the compressor. There would be a number of problems to be explored and solved before a successful application could be achieved, but the prospects look favorable at this time. One of the most useful next steps would be to continue to expand the knowledge base on refrigerant mixtures that would be made available to the manufacturers of refrigerators.
Integrated Analysis of Myocardial Blush and ST-Segment Elevation Recovery After Successful Primary Angioplasty (2002)

Rapid inspection of general aviation aircraft for security threats and contraband (2014)

In the US, inbound international general aviation flights need to be inspected daily. The objects of interest include explosives, weapons, currency, and contraband. An imaging system capable of seeing through the skin of the aircraft to identify suspicious items would considerably speed up the inspection process. For inspection of shipping containers, cars, trucks, and other vehicles, AS&E has fielded many hundreds of X-ray backscatter systems composed mostly of the Z Backscatter® Van and the Z Portal® system. Due to their complicated shapes, large variation in profiles and sizes, and particular operational settings, aircraft require a specialized type of scanner which has been developed by AS&E. Initial feasibility experiments have demonstrated that the X-ray backscatter method is very effective for detecting objects of interest inside aircraft of different types and sizes. Analysis of images illustrating the imaging tradeoffs is presented. In designing a product for this task the challenges are not limited to X-ray imaging. Due to operational issues, special considerations are needed for collision avoidance, zero-turn-radius, shape-following scanning, adaptive detection area, and video overlay. This paper details the requirements and tradeoffs involved in the system design, along with an overview of the prototype and its performance.
Localization of ovine placental lactogen in sheep placentomes by electron microscope immunocytochemistry (1981)

Ovine placental lactogen immunoreactivity was localized by the indirect immunocytochemical technique using peroxidase-antiperoxidase. The peptide hormone-like material was localized exclusively in the binucleate cell granules and Golgi region in the fetal chorionic epithelium and in granules of similar size and shape scattered throughout the contiguous syncytial layer of placentomes from sheep at 70, 114, 127 and 142 days of pregnancy. This localization supports the suggestion that in the sheep placentome the syncytial layer is formed by migration and fusion of the fetal chorionic binucleate cells.
Porous Polyethersulfone-Supported Zeolitic Imidazolate Framework Membranes for Hydrogen Separation (2012)

ZIF-8 thin layer has been synthesized on the asymmetric porous polyethersulfone (PES) substrate via secondary seeded growth. Continuous and dense ZIF-8 layer, containing microcavities, has good affinity with the PES support. Single gas permeance was measured for H2, N2, CH4, O2, and Ar at different pressure gradients and temperatures. Molecular sieving separation has been achieved for selectively separating hydrogen from larger gases. At 333 K, the H2 permeance can reach ∼4 × 10–7 mol m–2 s–1 Pa–1, and the ideal separation factors of H2 from Ar, O2, N2, and CH4 are 9.7, 10.8, 9.9, and 10.7, respectively. Long-term hydrogen permeance and H2/N2 separation performance show the stable permeability of the derived membranes.
3D Human Pose Estimation Using RGBD Camera (2021)

This work addresses a method to map the estimated 2D pose from a color image to 3D pose and obtain more accurate 3D keypoints. In this paper, the RGBD camera is used to simultaneously acquire color images and depth images. AlphaPose is used to estimate the 2D keypoints of the target, and the 2D keypoints are mapped to the corresponding depth maps to obtain the corresponding 3D keypoint. We adopt the parametric human body model, SMPL, as the 3D prior of the human body. The SMPL model and the data of point cloud are aligned by optimizing the global orientation and translation of the SMPL as well as optimizing the error of the SMPL vertices and the point cloud of the human body. The experimental results show that our method can effectively improve the accuracy of the existing 3D human pose and position estimation methods.
An aperture imaging system with instant decoding and tomographic capabilities. (1973)

A system for electronically decoding images from a coded aperture device is presented. The aperture is a single annulus in a thin lead (1/16-in.) plate and the coded images are stored in a commercial scan converter. Decoding is performed instantly (% see) by reading the image with an electron beam which scans in a helical fashion. Changing the diameter of the helix allows tomographic reconstruction.
New Dynamic Jiles-Atherton Hysteresis Model for Giant Magnetostrictive Material (2011)

To set-up a rate-dependent dynamic hysteresis model, eddy current loss in giant magnetostrictive material is represented by the loss in eddy current impedance. By combining static Jiles-Atherton hysteresis model, the equivalent circuit of giant magnetostrictive material is built, the relationship between eddy current impedance and magnetic field and magnetization is derived and the maximum eddy current impedance of the material is clculated. Effective magnetic permeability is applied to estimate the eddy current impedance as exciting rate or frequency gets high. Simulation and experiment results of exciting frequencies at 5Hz,10Hz,20Hz, are compared, showing experiment results are coincident with simulation ones, in term of magnitude order and tilt direction. It is demonstrated that effective permeability is feasible for eddy current impedance estimation and eddy current impedance-based dynamic Jiles-Atherton hysteresis model is able to reflect practical dynamic hysteresis.
Digital Fourier optics (1996)

Analog Fourier optical processing systems can perform important classes of signal processing operations in parallel, but suffer from limited accuracy. Digital-optical equivalents of such systems could be built that share many features of the analog systems while allowing greater accuracy. We show that the digital equivalent of any system consisting of an arbitrary number of lenses, niters, spatial light modulators, and sections of free space can be constructed. There are many possible applications for such systems as well as many alternative technologies for constructing them; this paper stresses the potential of free-space interconnected active-device-plane-based optoelectronic architectures as a digital signal processing environment. Implementation of the active-device planes through hybridization of optoelectronic components with silicon electronics should allow the realization of systems whose performance exceeds that of purely electronic systems.
Clinicopathological and prognostic significance of leucine-rich repeats and immunoglobulin-like domains protein 1 (LRIG1) in malignant tumors: A meta-analysis (2018)

<b>Background:</b> Accumulating studies have demonstrated that the expression of leucine-rich repeats and immunoglobulin-like domains protein1 (LRIG1) is associated with various types of tumors. However, the conclusions of previous studies are not completely consistent. Thus, we conducted this meta-analysis to further explore the authentic value of LRIG1 in cancer outcome and clinical significance. <b>Methods:</b> We systematically searched electronic databases including PubMed, Web of Science, Embase, Chinese National Knowledge Infrastructure and Wanfang database. The hazard ratios (HRs), odds ratio (OR) and 95 % confidence intervals (CI) were calculated for effect measures. <b>Results:</b> 16 qualified studies involving 2043 patients with cancer were enrolled. High LRIG1 expression was associated with a good prognosis in malignant tumors (HR: 0.49, 95% CI=0.39-0.59). Furthermore, positive expression rate of LRIG1 was distinctly lower in cancer tissues than that in normal tissues (OR: 0.09, 95% CI=0.05-0.17). Positive LRIG1 expression was definitely related with smaller tumor size (OR: 1.64, 95% CI=1.11-2.42), early tumor stage (OR: 3.67, 95% CI=1.87-7.21), well degree of differentiation (OR: 4.35, 95% CI=2.12-8.93) and negative recurrence (OR: 0.29, 95% CI=0.16-0.53). <b>Conclusions:</b> LRIG1 expression was associated with a good prognosis in terms of overall survival (OS) and might act as a predictive factor for characteristics of cancer patients.
Regioselective Ortho-Lithiation of Halopyridines and Synthesis of 3-Bromo-2,6-dimethoxy-4-diphenylphosphinopridine (2004)

Regioselective ortho-Lithiation of halopyridines was studied. Then 3-bromo-2,6-dimethoxy-4-diphenyiphosphinopridine was synthesized using 2,6-dimethoxypydine as a raw material through bromation, ortho-lithiation and electrophilic substitution. The whole yield may reach 57.9%.
The different effects of sodium bicarbonate and aluminium hydroxide on the absorption of indomethacin in man (1977)

Summary The influence of oral sodium bicarbonate and aluminium hydroxide on the absorption of indomethacin has been studied in normal volunteers. While sodium bicarbonate appeared to increase indomethacin absorption, aluminium hydroxide markedly reduced both the rate and extent of absorption. The buccal absorption of indomethacin over the pH range 5-9 was also studied in normal volunteers, and showed that the percentage absorption increased markedly as the pH was reduced. The clinical importance both of pH-partition and of adsorption are discussed in the context of antacid interactions. It is concluded that caution must be exercised when prescribing an antacid with other orally-administered drugs.
Kubelka-Munk Theory and the MTF of Paper (2003)

An experimental analysis of paper optical scattering is reported. The Kubelka-Munk parameters for scattering, S, absorption, K, thickness, L, and background reflectance, Rg, were measured for a variety of papers. Measurements were made of reflectance and transmittance using integrating sphere techniques, and the Kubelka-Munk Eqs. were inverted numerically to generate the corresponding S and K values. The modulation transfer function, MTF, of each paper sample was also measured by projecting a sharp edge onto the paper and measuring the resulting edge spread function. The MTF was calculated as the modulus of the Fourier transform of the derivative of the edge function. The inverse of the frequency at which the MTF = 0.5 was used as an index of the MTF and called κp. Values of κpwere compared to values of the Kubelka-Munk parameters. Through a combination of theory and empirical observation, a model was developed to relate κp to S, K, and L for Rg = 0. The results strongly indicate that an additional parameter is required in order to rationalize the observed MTF of papers. This additional parameter is suggested to be the scattering homogeneity of the paper.
