Stability and Resilience of Distributed Information Spreading in Aggregate Computing (2021)

Spreading information through a network of devices is a core activity for most distributed systems. As such, self-stabilizing algorithms implementing information spreading are one of the key building blocks enabling aggregate computing to provide resilient coordination in open complex distributed systems. This paper improves a general spreading block in the aggregate computing literature by making it resilient to network perturbations, establishes its global uniform asymptotic stability and proves that it is ultimately bounded under persistent disturbances. The ultimate bounds depend only on the magnitude of the largest perturbation and the network diameter, and three design parameters trade off competing aspects of performance. For example, as in many dynamical systems, values leading to greater resilience to network perturbations slow convergence and vice versa.
P3‐197: ADNI structural imaging markers are applicable to a community‐based Chinese cohort (2012)

While volumetric assessments of the brain can provide insights into atrophy for specific regions of interests, anatomical shape patterns characterizing both regional abnormalities and their precise localizations are often overlooked. Through analysis of the shapes of subcortical brain structures, this study aims to investigate the patterns of brain atrophy between a highly selective North American cohort and a community-based Asian cohort. Datasets used were from the Alzheimer Disease Neuroimaging Initiative (ADNI) and the Memory, Aging and Cognition Centre (MACC) study respectively, both large studies which have acquired structural MRI measures for the identification of biomarkers for dementia. We hypothesize that imaging markers derived from ADNI are applicable to the MACC population, regardless of their differences in vascular risk factors and cerebrovascular disease. Out of the 299 subjects analyzed, 189 were from ADNI (AD=56,NC=133) and 110 were from MACC (AD=23, NC=87). Shape changes of subcortical brain structures (hippocampus, amygdala, caudate, globus pallidus, putamen, thalamus) and lateral ventricles were characterized using computational anatomic mapping methods (Large Deformation Diffeomorphic Metric Mapping (LDDMM)-surface mapping algorithm). Data reduction (Multi-dimensional scaling) was employed to produce low dimensional embeddings of the shape signatures, which were in turn used as features in a soft-margin support vector machine (SVM). An SVM model was first created using the ADNI cohort before using the MACC cohort as a replication dataset for validation. Both ADNI and MACC cohorts showed similar patterns in brain atrophy, with classification rates of agreement varying from 70–80% between NC and AD. When the classifier trained from ADNI was applied to MACC, comparable sensitivities and specificities were observed in the hippocampus shape (classification rate 75%, specificity 75%, sensitivity 74%), amygdale shape (classification rate 76%, specificity 76%, sensitivity 78%) and ventricles shape (classification rate 77%, specificity 78%, sensitivity 74%). Results were improved when the shape signatures from individual structures were combined, resulting in higher classification rates (hippocampi and ventricles: specificity 82%, sensitivity 74%; hippocampi, ventricles, amygdala: specificity 79%, sensitivity 74%). Despite vascular risk differences between the ADNI and MACC cohorts, structural imaging markers extracted from the ADNI cohort are found to be applicable to a community-based Asian cohort.
Polymerizable phospholipids and their polymeric liposomes (1986)

Abstract Phospholipids containing polymerizable itaconate moieties were synthesized and their formation of liposomes was studied. Although the itaconate phospholipids alone form rather unstable liposomes by ultrasonication, mixtures with other phospholipids such as dipalmitoyl phosphatidylcholine, bis(2,4‐octadienoyl) phosphatidylcholine or cholesterol, form stable and single‐wall, small sized liposomes. The polymerizability of itaconate phospholipids and the stabilization of such mixed liposomes are discussed.
Zinc and copper, by high sensitivity-low energy ion scattering (2021)

Low energy ion scattering (LEIS) is an extremely surface sensitive technique that can quantitatively analyze the outermost atomic layer of a material. In LEIS and high sensitivity-low energy ion scattering (HS-LEIS), straightforward quantitation is available using reference and/or standard materials. Here, we present the HS-LEIS spectra of zinc obtained with 3 keV 4He+ and 4 keV 20Ne+ projectile ions. Zinc is an important material with a wide range of applications. Thus, these spectra should be useful standards/references for future applications. A high purity zinc foil was used for these measurements after the removal of the oxide layer. As a reference for the instrumental sensitivity, the spectra for Cu from a high purity foil are also included with this submission. Atomic sensitivity and relative sensitivity factors for Zn and Cu are reported.
Amino Acid Profiles of 44 Soybean Lines and ACE‐I Inhibitory Activities of Peptide Fractions from Selected Lines (2015)

Abstract Soybeans are cultivated in the United States chiefly for cooking oil, while the residue after oil extraction (soybean meal) is mostly used in animal feed formulations. High protein content in the defatted soybean meals led to the extraction of pure protein and its application in food products. We selected 44 soybean lines to determine their moisture and protein contents, and their amino acid composition was investigated. Soybean lines with high protein content, one high yielding (R95‐1705), and two high oleic acid (N98‐4445A, S03‐543CR), were selected for protein isolate preparation, hydrolysis using alcalase and gastro‐intestinal (GI) resistance. Furthermore, the GI resistant hydrolysates were fractionated and tested for angiotensin‐I‐converting enzyme (ACE‐I) inhibition activity. The amino acid analysis showed high methionine in the high protein and fatty acid lines (R05‐4494 and R05‐5491), and high cysteine content in one of the high oleic acid soybean line CRR05‐188 in comparison to the check lines (UA‐4805 and 5601‐T). The protein isolate with the highest purity (90–93 %) was derived from the selected lines N98‐4445A and S03‐543CR, and hydrolyzed using alcalase enzyme. The protein hydrolysates (500 µg/mL) showed inhibition of the ACE‐I by 49 %. The results from this study will promote the use of high oleic acid soybeans as a source of protein and peptides with functional activities.
Simple fixed-effects inference for complex functional models (2017)

We propose simple inferential approaches for the fixed effects in complex functional mixed effects models. We estimate the fixed effects under the independence of functional residuals assumption and then bootstrap independent units (e.g. subjects) to conduct inference on the fixed effects parameters. Simulations show excellent coverage probability of the confidence intervals and size of tests for the fixed effects model parameters. Methods are motivated by and applied to the Baltimore Longitudinal Study of Aging, though they are applicable to other studies that collect correlated functional data.
Accelerated Echo Planar J-Resolved Spectroscopic Imaging in Prostate Cancer and A Hybrid Dictionary Learning-Total Variation Reconstruction (2023)

Prospectively undersampled 5D echo-planar J-resolved spectroscopic imaging (EP-JRESI) data were acquired in 9 prostate cancer patients and 3 healthy controls. The 5D data was reconstructed using Dictionary learning (DL), Total Variation (TV), Perona-Malik (PM) and a hybrid DLTV method combining DL and TV. DLTV uses the gradient sparsity of TV and the learned dictionary-based sparsity of DL to further increase the transform sparsity of the data. The DLTV method unambiguously resolved 2D J-resolved peaks including myo-inositol, citrate, creatine, spermine and choline with an improved reconstruction that facilitates higher acceleration factors, leading to significant reduction in scan time.
Experimental determination of the specific opacity function for the Ba+HI→BaI(v=0)+H reaction (1992)

Through the use of laser-induced fluorescence spectroscopy, product rotational population distributions were recorded for the Ba(1S0)+HI(X 1Σ+)→BaI(X2 Σ+,v=0)+H(2S1/2) reaction under well-defined, crossed-beam conditions. In this kinematically constrained reaction, orbital angular momentum of the reagents Lreag is channeled almost exclusively into rotational angular momentum of the products Jprod. Consequently, ‖Jprod‖≂μvrelb, where μ is the reduced mass of the reactants, vrel is their relative velocity, and b is the impact parameter of the reactive collision. For relative velocity distributions with mean values ranging from 860 to 1000 m s−1, the BaI v=0 rotational distributions were found to peak sharply at high J values (≳420). Nonlinear least-squares analysis showed the specific opacity function (impact parameter distribution) for the formation of vibrationless BaI product to be exceptionally narrow (∼0.3 Å FWHM) with a pronounced maximum at the highest energetically allowed impact parameter ∼4.5 Å.

A new micro jerk sensor with viscous coupling (2003)

We propose a new method for detection of jerk (derivative of acceleration) which is suitable for the MEMS (micro electro mechanical system) sensor. The sensor has two vibrators that arc connected with viscous coupling, and the sensor converts the jerk to the displacement of the second vibrator. In this paper, we explain a new principle of the jerk detection with a two degrees freedom sensor model and analyze the behavior of the sensor model to the viscosity.
Galactoglucomannan oligosaccharide supplementation affects nutrient digestibility, fermentation end-product production, and large bowel microbiota of the dog1 (2010)

A galactoglucomannan oligosaccharide (GGMO) obtained from fiberboard production was evaluated as a dietary supplement for dogs. The GGMO substrate contained increased concentrations of oligosaccharides containing mannose, xylose, and glucose, with the mannose component accounting for 35% of DM. Adult dogs assigned to a 6 × 6 Latin square design were fed 6 diets, each containing a different concentration of supplemental GGMO (0, 0.5, 1, 2, 4, and 8%) that replaced dietary cellulose. Total tract DM and OM apparent digestibilities increased (P < 0.001) linearly, whereas total tract CP apparent digestibility decreased (P < 0.001) linearly as dietary GGMO substrate concentration increased. Fecal concentrations of acetate, propionate, and total short-chain fatty acids increased (P ≤ 0.001) linearly, whereas butyrate concentration decreased (P ≤ 0.001) linearly with increasing dietary concentrations of GGMO. Fecal pH decreased (P ≤ 0.001) linearly as dietary GGMO substrate concentration increased, whereas fecal score increased quadratically (P ≤ 0.001). Fecal phenol (P ≤ 0.05) and indole (P ≤ 0.01) concentrations decreased linearly with GGMO supplementation. Fecal biogenic amine concentrations were not different among treatments except for phenylethylamine, which decreased (P < 0.001) linearly as dietary GGMO substrate concentration increased. Fecal microbial concentrations of Escherichia coli, Lactobacillus spp., and Clostridium perfringens were not different among treatments. A quadratic increase (P ≤ 0.01) was noted for Bifidobacterium spp. as dietary GGMO substrate concentration increased. The data suggest positive nutritional properties of supplemental GGMO when incorporated in a good-quality dog food.
Prediction of heated jet radiation with account of turbulent fluctuations (1997)

The results of the investigations of turbulent fluctuation influence on heat radiation of hydrocarbon fuel combustion jets are presented. These results show that temperature fluctuations are one of the basic factors forming radiation fields on non-reactive jets. The approach used is based on optically thin pulsation approximation that allow to account for temperature fluctuation contribution using local averaging of optical characteristics in radiation transfer equation. Such averaging may be completed using model probability density functions (PDF) of temperature and concentration. Several PDF models were verified on the basis of measured and calculated jet IR radiance comparison.
[Effect of intraoperative blood loss on the function of natural killer cells in tumors of the upper gastrointestinal tract]. (1996)

The activity of natural killer cells was measured perioperatively in 39 patients with esophageal and gastric cancer and was correlated with intraoperative blood loss. The activity of natural killer cells in all patients sank significantly (p < 0.05) on the fourth postoperative day to their original values. In the 24 patients with an intraoperative blood loss of more than 700 ml, the activity of the natural killer cells decreased significantly (p < 0.05) on the fourth postoperative day, in contrast to those 15 patients with an intraoperative blood loss of less than 500 ml; intraoperative blood loss and activity of natural killer cells show a correlation of R2 0.82.
Accelerating Unstructured Volume Rendering with Joint Bilateral Upsampling (2009)

We present an image-space acceleration technique that allows real-time direct volume rendering of large unstructured volumes. Our algorithm operates as a simple post-process and can be used to improve the performance of any existing volume renderer that is sensitive to image size. Using a joint bilateral upsampling filter, images can be rendered efficiently at a fraction of their original size, then upsampled at a high quality using properties that can be quickly computed from the volume. We show how our acceleration technique can be efficiently implemented with current GPUs and used as a post-process for a wide range of volume rendering algorithms and volumetric datasets.
An extension of UML by protocols for multi-agent interaction (2002)

Recently, a cooperation has been established between the foundation of intelligent physical agents (FIPA) and the object management group aiming to increase acceptance of agent technology in industry by relating to de facto standards (object-oriented software development) and supporting the development environment throughout the full system life cycle. As a first result of this cooperation, Bauer (1999) proposed agent UML, an extension of the unified modeling language (UML), a de facto standard for object-oriented analysis and design. In this paper, we describe the heart of agent UML, i.e., mechanisms to model protocols for multi-agent interaction. Particular UML extensions described in this paper include protocol diagrams, agent roles, multi-threaded lifelines, extended UML message semantics, nested and interleaved protocols, and protocol templates.
N-polar GaN Electronics (2007)

In this paper, we discuss recent developments in our work on N-polar GaN heterostructure transistors. While most work in GaN devices has been on Ga-polar films, the opposite direction of polarization provides advantages that could be useful for different device applications. We will first discuss implications of the reversed polarization on transistor design.
The First Step into the Brain: Uptake of NIO‐PBCA Nanoparticles by Endothelial Cells in vitro and in vivo, and Direct Evidence for their Blood–Brain Barrier Permeation (2008)

By using fluorescent polysorbate 80 coated poly(n-butylcyanoacrylate) (PBCA) nanoparticles in an in vivo study, direct evidence was found for the presence of nanoparticles entering the brain and retina of rats. The nanoparticles, prepared with a miniemulsion process, were labeled in situ with a fluorescent dye and coated with polysorbate 80. After preparation the particle size, zeta potential, and the molecular weight distribution were determined. BMEC cells were used as an in vitro model for the BBB. The cells showed significant uptake of the particles, but no transcytosis could be observed in vitro. After applying the particles to the animals at two concentrations, cryosections of the brains and retinas were prepared. Regarding the sections of the rats that received the lower dose, co-localization of the applied fluorescent particles and the stained endothelial cells could be detected in the brain and retina, indicating particle internalization in the endothelial cells. Applied at higher doses, the particles could be detected within the brain and retina with few co-localized signals, suggesting passage through the blood-brain and blood-retina barriers.
Selective Laser Sintering of Multilayer, Multimaterial Circuit Components (2006)

Selective laser sintering (SLS) is presented for the creation of multilayer circuit components compatible with microwave frequencies. SLS is a one step process that uses a laser to pattern and fully sinter screen printable inks without the use of any high temperature post processing. For the first time, this process is demonstrated for multiple layers of material with varying properties, such as metals and dielectrics. Sequentially sintering conventional thick film materials is used to create functional layers, both conductive and dielectric, in a layer by layer fashion, forming metal-insulator-metal (MIM) capacitors and spiral inductors on soda-lime glass

Magnetic field assisted nanoparticle dispersion (2008)

Magnetohydrodynamic nanoparticle dispersion is an energy efficient method to deaggregate nanoparticles, combining hydrodynamic forces of turbulent flow with Lorentz forces generated by a magnetic field.
Vimentin fibers orient traction stress (2017)

The intermediate filament vimentin is required for cells to transition from the epithelial state to the mesenchymal state and migrate as single cells; however, little is known about the specific role of vimentin in the regulation of mesenchymal migration. Vimentin is known to have a significantly greater ability to resist stress without breaking in vitro compared with actin or microtubules, and also to increase cell elasticity in vivo. Therefore, we hypothesized that the presence of vimentin could support the anisotropic mechanical strain of single-cell migration. To study this, we fluorescently labeled vimentin with an mEmerald tag using TALEN genome editing. We observed vimentin architecture in migrating human foreskin fibroblasts and found that network organization varied from long, linear bundles, or "fibers," to shorter fragments with a mesh-like organization. We developed image analysis tools employing steerable filtering and iterative graph matching to characterize the fibers embedded in the surrounding mesh. Vimentin fibers were aligned with fibroblast branching and migration direction. The presence of the vimentin network was correlated with 10-fold slower local actin retrograde flow rates, as well as spatial homogenization of actin-based forces transmitted to the substrate. Vimentin fibers coaligned with and were required for the anisotropic orientation of traction stresses. These results indicate that the vimentin network acts as a load-bearing superstructure capable of integrating and reorienting actin-based forces. We propose that vimentin's role in cell motility is to govern the alignment of traction stresses that permit single-cell migration.
Mechanical, Rheological and Thermal Properties of Polystyrene/1-Octadecanol Modified Carbon Nanotubes Nanocomposites (2014)

The results of the studies on the functionalization of multi-walled carbon nanotubes (MWCNT) with 1-octadecanol and its usage as reinforcing filler in the bulk polymerization of styrene are reported in this article. Both unmodified and modified CNTs were utilized in different loadings, however, without any initiator. The resulting composites were characterized by using mechanical testing, differential scanning calorimetry, thermogravimetric analysis and melt rheology. The tensile tests show the addition of 0.5wt% of CNT-C18 results in 19.5% increment of Young's modulus. The DSC study shows a decrease in Tg values of prepared PS/CNT nanocomposite. The rheological study was conducted at 190°C and shows that addition of pure CNT increased the viscoelastic behavior of the PS matrices, while the CNT-C18 act as plasticizer. Thermogravimetric analysis shows that the incorporation of CNT into PS enhanced the thermal properties significantly.
Metal-on-Metal Hip Arthroplasty Does Equally Well in Osteonecrosis and Osteoarthritis (2008)

Many previous reports suggest total hip arthroplasty performs suboptimally in young patients with osteonecrosis. We retrospectively compared the performance of metal-on-metal articulation in a select group of 107 patients with 112 hips (98 uncemented and 14 cemented stems) 60 years of age or younger with either osteonecrosis (27 patients, 30 hips) or primary osteoarthritis (80 patients, 82 hips). We evaluated all patients with patient-generated Harris hip score forms and serial radiographs. Five mechanical complications were caused by impingement, two with pain, two dislocations, and one liner dissociation. At a minimum followup of 2.2 years (mean, 5.5 years; range, 2.2-11.7 years), we observed no osteolysis or aseptic loosening in the osteonecrosis group, whereas one osteoarthritic hip had cup revision for loosening (none showed evidence of osteolysis). None of the stems were loose. Patients with osteonecrosis or primary osteoarthritis were similar in clinical and radiographic performance. The patients with metal-on-metal hip arthroplasty for osteonecrosis had no revisions for aseptic loosening, but did have one liner change in a cup for painful impingement.
