Enhanced Surface Plasmon Resonance on a Smooth Silver Film with a Seed Growth Layer (2010)

This paper reports an effective method to enhance the surface plasmon resonance (SPR) on Ag films by using a thin Ni seed layer assisted deposition. Ag films with a thickness of about 50 nm were deposited by electron beam evaporation above an ultrathin Ni seed layer of approximately 2 nm on both silicon and quartz substrates. The root-mean-square (rms) surface roughness and the correlation length have been reduced from >4 nm and 28 nm for a pure Ag film to approximately 1.3 and 19 nm for Ag/Ni films, respectively. Both experimental and simulation results show that the Ag/Ni films exhibit an enhanced SPR over the pure Ag film with a narrower full width at half-maximum. Ag films with a Ge seed layer have also been prepared under the same conditions. The surface roughness can be reduced to less than 0.7 nm, but narrowing of the SPR curve is not observed due to increased absorptive damping in the Ge seed layer. Our results show that Ni acts as a roughness-diminishing growth layer for the Ag film while at the same time maintaining and enhancing the plasmonic properties of the combined structures. This points toward its use for low-loss plasmonic devices and optical metamaterials applications.
Airway hyperresponsiveness and inflammation induced by toluene diisocyanate in guinea pigs. (1985)

We examined the changes in airway responsiveness to increasing doses of an acetylcholine aerosol in anesthetized and ventilated guinea pigs 2, 6, or 24 h after exposure to 2 ppm toluene diisocyanate (TDI) or 2 h after exposure to air or 1 ppm TDI. Pulmonary resistance (RL) after the animals inhaled a buffered saline aerosol was used as baseline and was similar for air and TDI groups. The concentration of acetylcholine calculated to cause a 200% increase in RL was significantly lower for animals studied at 2 h (0.68%) or at 6 h (0.77%), but not at 24 h (2.39%), after TDI than for air animals (3.07%). The increase in airway responsiveness in the TDI-exposed animals was associated with histologic changes in the trachea and intrapulmonary airways. Exposure to 2 ppm TDI caused a patchy loss of cilia, shedding of epithelial cells into the airway lumen, and an influx of inflammatory cells into the trachea and other airways. In the lamina propria of the trachea, the concentration of extravascular polymorphonuclear leukocytes (PMN) was 13- to 26-fold greater in animals studied 2 or 6 h after exposure to 2 ppm TDI or at 2 h after 1 ppm TDI than in animals exposed to air. The concentration of PMN in the epithelium was significantly increased only in animals examined 2 h after 2 ppm TDI. Exposure to TDI also caused an influx of eosinophils into the tracheal mucosa. This influx occurred later and was more persistent than the influx of PMN. These results indicate that a single exposure to TDI can cause an increase in airway responsiveness that is associated with epithelial injury and acute airway inflammation.
Open-label study of the safety and effectiveness of long-term therapy with extended-release tramadol in the management of chronic nonmalignant pain (2007)

Individualized dose titration and limiting once-daily therapy with tramadol ER to the maximum recommended daily dose of 300 mg may balance tolerability and analgesic effects of tramadol ER in patients with chronic, nonmalignant pain.
Blood pressure estimation from pulse wave velocity measured on the chest (2013)

Recently, monitoring of blood pressure fluctuation in the daily life is focused on in the hypertension care area to predict the risk of cardiovascular and cerebrovascular disease events. In this paper, in order to propose an alternative system to the existed ambulatory blood pressure monitoring (ABPM) sphygmomanometer, we have developed a prototype of small wearable device consisting of electrocardiogram (ECG) and photopelthysmograph (PPG) sensors. In addition, it was examined whether blood pressure can be estimated based on pulse wave transit time (PWTT) only by attaching that device on the surface of the chest. We indicated that our system could also sense tendency of time-dependent change of blood pressure by measuring pulse of vessel over the sternum while its propagation distance is short.

Color Operation with BGP Label Unicast (2019)

This document specifies how to carry colored path advertisement via an
enhancement to the existing protocol BGP Label Unicast. It would allow
backward compatibility with RFC8277. The targeted solution is to use
stack of labels advertised via BGP Label Unicast 2.0 for end to end
traffic steering across multiple IGP domains. The operation is similar
to Segment Routing. This proposed protocol will convey the necessary
reachability information to the ingress PE node to construct an end to

PARTICLE SYNTHESIS, CHARACTERIZATION, AND PROPERTIES OF FILLED POLYMER SYSTEMS (2006)

This dissertation presents results on the reinforcement of an elastomer system using different types of fillers and comparing the resulting mechanical properties of compounds made with these fillers.The analytic approach uses two classical models with which fillers are thought to reinforce elastomers.The first mechanism being based on filler structure while the second involves the interaction of the filler with an elastomer.Two new types of fillers are investigated: a fumed silicacarbon composite and a layered silicate.These fillers are compounded into elastomers using formulations that are standard in the tire industry for tire tread compounds.This work builds off of previous studies that use techniques such as microscopy and gas adsorption to characterize filler structure by adding the use of small-angle x-ray scattering to characterize fillers based on three structural levels.Classical rubber elasticity principles with recent fractal model analysis are used to describe how the structural levels of the fillers relate to elastomer reinforcement.Analysis of the SAXS data gives information about the size of the primary particle and of the aggregate formed by these primary particles.It is found, through analyzing the SAXS data, that the ratio of these two structural sizes gives the degree of aggregation or the number of particles in an aggregate..The measurement and analysis of the degree of aggregation and how it correlates with measured mechanical properties of compounds is presented in this dissertation.The results from the USAXS and the mechanical testing of elastomers showed that the degree of aggregation, z, helps to identify what is a 'reinforcing' filler.Higher degree of aggregation correlated with better mechanical properties.While other studies have shown the effects of surface modifications, filler concentration, and surface area, the studies in this dissertation conclude that the degree of aggregation is an important parameter that can predict the reinforcing behavior of aggregated silica fillers.
AtHMA3, a P1B-ATPase Allowing Cd/Zn/Co/Pb Vacuolar Storage in Arabidopsis  (2008)

The Arabidopsis (Arabidopsis thaliana) Heavy Metal Associated3 (AtHMA3) protein belongs to the P1B-2 subgroup of the P-type ATPase family, which is involved in heavy metal transport. In a previous study, we have shown, using heterologous expression in the yeast Saccharomyces cerevisiae, that in the presence of toxic metals, AtHMA3 was able to phenotypically complement the cadmium/lead (Cd/Pb)-hypersensitive strain ycf1 but not the zinc (Zn)-hypersensitive strain zrc1. In this study, we demonstrate that AtHMA3 in planta is located in the vacuolar membrane, with a high expression level in guard cells, hydathodes, vascular tissues, and the root apex. Confocal imaging in the presence of the Zn/Cd fluorescent probe BTC-5N revealed that AtHMA3 participates in the vacuolar storage of Cd. A T-DNA insertional mutant was found more sensitive to Zn and Cd. Conversely, ectopic overexpression of AtHMA3 improved plant tolerance to Cd, cobalt, Pb, and Zn; Cd accumulation increased by about 2- to 3-fold in plants overexpressing AtHMA3 compared with wild-type plants. Thus, AtHMA3 likely plays a role in the detoxification of biological (Zn) and nonbiological (Cd, cobalt, and Pb) heavy metals by participating in their vacuolar sequestration, an original function for a P1B-2 ATPase in a multicellular eukaryote.

Effects of Adsorbents Used as Supports for Titanium Dioxide Loading on Photocatalytic Degradation of Propyzamide (1996)

Photodecomposition in aqueous solution of 3,5-dichloro-N-(3-methyl-1-butyn-3-yl)benzamide, whose popular name is propyzamide, was investigated using naked TiO2 and TiO2-loaded adsorbent supports as photocatalysts. The adsorbent supports used were zeolite (mordenite), silica, and activated carbon. The use of adsorbent supports was found to enhance the rate of mineralization of propyzamide and to reduce the concentration of solution-phase intermediates. The experimental results suggest that the adsorbent support concentrates a target substrate of low solution-phase concentration on its surface, providing the substrate-rich environment at the adsorbent/TiO2 interface. This concentration effect results in an enhanced rate of propyzamide mineralization. The intermediates are also retained on the adsorbent support and subsequently decomposed, thereby reducing the concentration of possibly toxic intermediates in the bulk solution.
Smelly Maps: The Digital Life of Urban Smellscapes (2021)

Smell has a huge influence over how we perceive places. Despite its importance, smell has been crucially overlooked by urban planners and scientists alike, not least because it is difficult to record and analyze at scale. One of the authors of this paper has ventured out in the urban world and conducted ``smellwalks'' in a variety of cities: participants were exposed to a range of different smellscapes and asked to record their experiences. As a result, smell-related words have been collected and classified, creating the first dictionary for urban smell. Here we explore the possibility of using social media data to reliably map the smells of entire cities. To this end, for both Barcelona and London, we collect geo-referenced picture tags from Flickr and Instagram, and geo-referenced tweets from Twitter. We match those tags and tweets with the words in the smell dictionary. We find that smell-related words are best classified in ten categories. We also find that specific categories (e.g., industry, transport, cleaning) correlate with governmental air quality indicators, adding validity to our study.
Longitudinal in Vivo Analysis of the Region-Specific Efficacy of Parathyroid Hormone in a Rat Cortical Defect Model (2008)

PTH has been shown to enhance fracture repair; however, exactly when and where PTH acts in this process remains to be elucidated. Therefore, we conducted a longitudinal, region-specific analysis of bone regeneration in mature, osteopenic rats using a cortical defect model. Six-month-old rats were ovariectomized, and allowed to lose bone for 2 months, before being subjected to bilateral 2-mm circular defects in their femoral diaphyses. They were then treated for 5 wk with hPTH1-38 at doses of 0, 3, 10, or 30 microg/kg . d and scanned weekly by in vivo quantitative computed tomography. Quantitative computed tomography analyses showed temporal, dose-dependent increases in mineralization in the defects, intramedullary (IM) spaces, and whole diaphyses at the defect sites. Histomorphometry confirmed PTH stimulation of primarily woven bone in the defects and IM spaces, but not the periosteum. After necropsy, biomechanical testing identified an increase in strength at the highest PTH dose. Serum procollagen type I N-terminal propeptide concentration showed a transient increase due to drilling, but procollagen type I N-terminal propeptide also increased with PTH treatment, whereas tartrate-resistant acid phosphatase unexpectedly decreased. Analyses of lumber vertebra confirmed systemic efficacy of PTH at a nonfracture site. In summary, PTH dose dependently induced new bone formation within defects, at endocortical surfaces, and in IM spaces, resulting in faster and greater bone healing, as well as efficacy at other skeletal sites. The effects of PTH were kinetic, region specific, and most apparent at high doses that may not be entirely clinically relevant; therefore, clinical studies are necessary to clarify the therapeutic utility of PTH in bone healing.
Slower processing, weaker beta 2-M association, and lower surface expression of H-2Ld are influenced by its amino terminus. (1986)

To determine why Ld antigens are expressed on the cell surface at levels three to four times lower than Dd or Kd antigens, pulse-chase experiments were used to compare their rates of biosynthesis and processing. Electrophoresis on sodium dodecyl sulfate gradient polyacrylamide gels resolved immunoprecipitates of each of these histocompatibility complex class I molecules into a slower and faster species. During the chase period, the faster migrating species appeared to be converted to the slower migrating species in a time-dependent manner. However, the conversion of Ld from the faster to the slower migrating species proceeded significantly more slowly than did the conversion of either Dd or Kd. Endoglycosidase H sensitivity and cell surface radiolabeling were used to determine the glycosylation state and cell location of each species of Ld and Dd. The results from these experiments, along with the pulse-chase studies and cytofluorometric analyses, suggest that Ld possesses a much slower rate of processing from a faster migrating, high mannose-bearing species to a slower migrating, complex oligosaccharide-bearing species found on the cell surface. Analysis of the beta 2-microglobulin (beta 2-m) association confirmed that Ld is associated with less beta 2-m than Dd. To localize the structures on class I molecules influencing their surface expression, rate of processing, and beta 2-m association, the Ddm1 molecule was analyzed. The Ddm1 molecule of the mutant B10.D2-H-2dm1 has previously been shown to be a chimeric Dd (amino-terminal)/Ld (carboxyl-terminal) polypeptide. The surface expression, processing and beta 2-m association of Ddm1 were found to be similar to Dd rather than Ld, suggesting that each of these phenomena are influenced by protein structure in the amino terminus.

Hierarchical Networks and the Subnetwork Partition Problem. (1985)

Abstract This paper describes the problem of having a network organized hierarchically, and having a subnetwork becoming physically partitioned. It describes how to detect partitions, how to identify individual partitions, how to locate nodes within a partition, how to route to a given partition, and how to route through a partitioned subnetwork.
Bondage of children: a chronicle of the long suffering (2016)

Although Cuba's indigenous systems of slavery have been extensively described in the historical literature, comparatively little attention has been paid to analyzing its long term impact on economic and political development. Based on data collected from anthropological records we conduct an econometric analysis. We find that indigenous slavery is robustly and negatively associated with current income levels, but not with income levels immediately after independence. We explore one channel of transmission from indigenous slavery to income growth consistent with this changing effect over time and find evidence that indigenous slavery impeded the development of capable and accountable states in Cuba Language: en
Does Infection Play a Role in Breast Capsular Contracture? (1981)

The formation of capsular contracture around silicone implants continues to be the most common complication of augmentation mammaplasty. To date, the etiologic factors in the formation of capsular contractures have remained inconclusive. In the present study, the role of subclinical infection with S. epidermidis as a cause of capsular contracture was evaluated in 16 rabbits using miniature silicone implants. All the implants on the side contaminated with varying concentrations of S. epidermidis developed breast capsular contractures. Using Baker's classification, they were graded III or IV, while the controls were all considered to be either grade I or II. Grossly, the capsules on the contaminated side were firm, fibrous, and 2 to 3 times thicker than the controls, and this was confirmed histologically using micrometry. Implants contaminated with 10(7) bacteria uniformly extruded. The present study seems to indicate that subclinical infection with Staphylococcus epidermidis may be one of the causes of capsular contracture around breast implants.
Drug combinations as rational antihypertensive therapy (1974)

The goal of antihypertensive therapy is to restore blood pressure to normal with as few side effects as possible. Usually this is best accomplished by skillfully combining two or more drugs in the regimen. A diuretic should be the cornerstone on which the regimen is built; for many patients with mild hypertension, a diuretic will be the only drug needed. Selection of drugs should be influenced by severity of hypertension and by the presence of complications and preexisting symptoms or conditions that, though unrelated to hypertension, might be aggravated by certain drugs. Combination tablets should be employed in selected patients only.
Correlation between Hypomethylation of DNA and Expression of Globin Genes in Friend Erythroleukemia Cells (1977)

This report identifies L-ethionine as an inducer of differentiation in murine erythroleukemia cells. When Friend erythroleukemia cells are grown in the presence of 4mM L-ethionine, globin mRNA accumulates and in 4-5 days, 25-30% of the cells in the culture contain hemoglobin. Incubation of the cells with bromodeoxyuridine prevents both ethionine-induced accumulation of globin mRNA and erythroide differentiation. At the concentration where L-ethionine acts as an inducer of FL cell differentiation it inhibits methylation of DNA and tRNA in vivo but does not prevent macromolecular synthesis or cell division. To establish whether a link existed between inhibition of a specific methyltransferase and activation of globin synthesis in FL cells, we examined the degree of hypomethylation of DNA and tRNA from FL cells induced to differentiate with dimethylsulfoxide and butyrate. In contrast to the tRNA from ethionine-treated cells, tRNA from cells induced by butyrate or Me2SO cannot be methylated in vitro using homologous enzymes. DNA isolated from cells exposed to any of the three inducers, however, was significantly hypomethylated when compared with DNA from uninduced cells. These data suggest that methylation of DNA may play a role in the regulation of gene expression.
Numerical Solution of the Planar Hydrostatic Foil Bearing (1979)

The steady state problem of the planar hydrostatic foil bearing is analyzed and solved numerically. Two techniques of solution are used. One method is simulation in time with asymptotic approach to steady state. This is achieved by a preprocessor which automatically sets up the numerical computer program. The second method is an iterative shooting technique. The results agree well with one another. Curves of pressure and typical film thickness versus flow are presented.
VFD control methodologies in High Pressure Grinding drive systems (2012)

High Pressure Grinding Roll (HPGR) technology is a reliable workhorse in the cement industry. Because of its generally overall lower cost per ton of material processed, HPGR applications have been growing in popularity in recent years in the mineral processing industry. HPGRs can be combined with variable frequency drives (VFD) to provide added process flexibility and reduce roll wear rates. This flexibility and reduced wear can increase uptime and overall mill throughput. The nature of the HPGR mill design with its independent grinding rolls requires an innovative solution for the control of the rolls when driven by a VFD. This paper reviews available drive control methods to determine a solution that will promote low roll wear and maximum grinding efficiency.
Efficient Charging Pad for Unmanned Aerial Vehicle Based on Direct Contact (2018)

Recently there has been significant interest in the development of autonomously Unmanned Aerial Vehicles (UAVs), especially the rotor-based robots, which are highly maneuverable and can vertically take-off and land. However, the discharge characteristics and charge storage capacity limitations of their lithium-ion battery can restrict their flight time endurance. The utilization of an automatic drone charging station is therefore desirable for these robots. This paper proposes a fully automatic contact-based charging station for UAVs to recharge UAV's and thereby solve the UAV's flight endurance limitations. The ground station comprises square-shaped copper plates of consecutively polarized positively and negatively in the form of a chess board with specific dimensions to ensure electrical contact when landing. The design methodology employed with the charging station accounts for the variations of the orientation of the UAV after landing on the platform. Furthermore, this innovation employs an autonomous recharging process after touchdown. Subsequently, this technology relaxes usual flight time constraints and improves overall mission times. The UAV equipped with a suitable hardware circuit the onboard circuit consists of six bridge diode rectifiers to modulate the polarity of the four UAV's contact terminals that allows autonomous recharge regardless of the yaw angle between UAVs and the charging pad platform, this, in turn, simplifies landing protocols. The result shows that the charging circuit successfully charged the UAV battery until 12.5v.
