Comparison of the Effective Radius of Sterically Stabilized Latex Particles Determined by Small-Angle X-ray Scattering and by Zero Shear Viscosity (1998)

The influence of an adsorbed layer of a surfactant on the flow behavior of a latex is considered. The system studied consists of a poly(styrene) core latex without chemically bound charges (diameter: 146 nm) and a layer of poly(ethylene oxide) chains (length: 80 ethylene oxide units) affixed to the surface of the particles through adsorption of the surfactant Lutensol AT80 (C16-18EO80). Both the core latex as well as the latex covered by surfactant have been studied by small-angle X-ray scattering (SAXS). The hydrodynamic thickness of the layer was determined by rheology to be 11.7 nm whereas SAXS gives an extension of the layer of approximately 12 nm. The result demonstrates that realistic hydrodynamic radii of latex particles result from viscosimetric measurements. Relative viscosities measured at higher volume fractions compare favorable with a recent experimental master curve proposed for suspensions of hard spheres (Meeker, S. P.; Poon, W. C. K.; Pusey, P. N. Phys. Rev. E 1997, 55, 5718).
A SAW-less receiver front-end with low power active self-interference canceler (2015)

A receiver front-end based on an active self-interference canceler is presented. The active canceler combines programmable gain and phase in a single stage and was co-designed with a highly-linear LNA, achieving low noise and low power. A cross-modulation mechanism of Self Interference (SI) canceler was identified and strongly suppressed thanks to internal resistive feedback, enabling high effective IIP3 with respect to TX leakage. TX leakage of up to -4dBm of power is suppressed by over 30dB at the input of the LNA, with benefits for the entire receiver in terms of IIP3, IIP2 and reciprocal mixing. The LNA+canceler, designed in a 40nm CMOS technology, consumes <;25mW has a NF of 2.2-3.1dB and an IIP3 of 38dBm with -8dBm TX leakage.

Thermal Stability of PIII Deposited Hard-Coatings with Compositions Between Diamond-Like Carbon and Amorphous Silicon-Carbonitride (2007)

By increasing the addition of Si and N to diamond-like carbon (DLC), the amorphous ceramic silicon-carbonitride (SiCN) can be obtained. An advantage of SiCN compared to DLC is its high thermal stability, represented by a crystallisation temperature of 1 500 °C and its increased oxidation resistance. To investigate the thermal stability of a-SiCN:H thin films, samples with different carbon contents have been produced by plasma immersion ion implantation and deposition (PIII&D). The films have been annealed at temperatures up to 1 000 °C in O2 as well as Ar. By examining the chemical composition, bonding structure and mechanical properties, a distinct carbon fraction could be determined, which marks the transition from (doped) a-C:H with low thermal stability to a-SiCN:H with high temperature resistance.
Automatic Temperature Regulation and Recording in Precision Adiabatic Calorimetry (1957)

In connection with a precision adiabatic calorimeter used for heat-capacity measurements up to 500°C, there is described apparatus for automatically controlling and recording the temperature difference between the calorimeter and its surroundings and for evaluation of the heat leak by electronic integration of the time-temperature difference function.
Spare Parts Supply Chain Shipment Decision Making in a Deterministic Environment (2017)

Determining the optimal lot size is a well discussed problem across many industries. This paper suggests a deterministic approach to shipment decision taking in a deterministic environment of spare parts supply chain. The model considered a deterministic forecast for the incoming faulty units. An objective function was modeled by taking in consideration three main elements: the number of malfunctioned units, the shipping cost and the storage cost. A deterministic forecast allowed calculating the cost effective schedule of shipments and its lot sizes. The purpose of this paper it to study the reverse logistics supply chain of a typical telecom devices company (that offers warranty/repairing services) and try to reduce its transportation and handling costs in order to bring added-value to the customer and by doing so, expand the competitive advantage of the company.
A Quantitative Test For Form Closure Grasps (2005)

Grasp and manipulation planning of slippery objects often relies on the 'lform'closure grasp, which can he maintained regardless of the external force applied to the object. Despite its importance, a quantita- tive test ,for form closure valid for any number of contact points is not availuhle. The primary contribution of this paper is the introduction of such a test formulated as a lineor program, of which the optimal objective value provides a measure of how far a grasp is from losing ,form While the test is formulated for frictionless grasps, we discuss how it can be modified to identify grasps with 'yrictional fortn closure.

Dyads for Photoinduced Charge Separation Based on Platinum Diimine Bis(acetylide) Chromophores:  Synthesis, Luminescence and Transient Absorption Studies (2003)

The platinum diimine bis(acetylide) chromophore was utilized to explore photoinduced intramolecular reductive quenching with phenothiazine donors in chromophore-donor dyad complexes. Compounds of the general formula Pt(X(2)-bpy)(C triple bond C-p-C(6)H(4)CH(2)(D))(2) (where D = phenothiazine (PTZ) or trifluromethylphenothiazine (TPZ) and X = (t)Bu or CO(2)Et) were synthesized from the corresponding Pt(X(2)-bpy)Cl(2) and aryl acetylene by a CuI-catalyzed coupling reaction. Solvent dependence was explored for the system with X = (t)Bu in MeCN, CH(2)Cl(2), EtOAc, and toluene. Electron transfer quenching of the (3)MLCT excited state of the platinum diimine bis(acetylide) takes place in MeCN leaving no intrinsic emission from the excited state, but in toluene both the PTZ and TPZ dyad complexes exhibit no emission quenching. Picosecond pump-probe transient absorption (TA) experiments were used to monitor decay of the (3)MLCT excited state and electron transfer to form the charge-separated (CS) state. Electrochemical measurements were used to estimate the driving force for charge recombination (CR), with deltaE(CR) based on the reduction potential corresponding to Pt(X(2)-bpy)(C triple bond C-Ar)(2) --> Pt(X(2)-bpy(*)(-))(C triple bond C-Ar)(2) and the oxidation corresponding to donor --> donor(*)(+). Kinetic information from the TA measurements was used to correlate rate and driving force with the electron transfer reactions. Concomitant with the decay of the (3)MLCT excited state was the observation of a transient absorption at ca. 500 nm due to formation of the PTZ or TPZ radical cation in the CS state, with the rate of charge separation, k(CS), being 1.8 x 10(9) to 2 x 10(10) s(-1) for the three dyads explored in MeCN and 1:9 CH(2)Cl(2)/MeCN. The fastest rate of CR occurs for X = CO(2)Et and D = PTZ, the compound with smallest deltaE(CR) = 1.71 V. The rate of CR for dyads with X = (t)Bu and D = PTZ or TPZ was estimated to be 1.7-2.0 x 10(8) s(-1) in MeCN. The slower rate corresponds to a greater driving force for CR, deltaE(CR) = 2.18 and 2.36 V for D = PTZ and TPZ, respectively, suggesting that the driving force for charge recombination places it in the Marcus inverted region.
Nonlinear elasticity and pressure-dependent wave speeds in granular media (1990)

Abstract Following is an analysis of the small-strain nonlinear elasticity of granular media near states of zero stress, as it relates to the pressure-dependent incremental linear elasticity and wave speeds. The main object is elucidation of the p½ dependence of incremental elastic moduli on pressure p, a dependence observed in numerous experiments but found to be at odds with the p½ scaling predicted by various micromechanical models based on hertzian contact. After presenting a power-law continuum model for small-strain nonlinear elasticity, the present work develops micromechanical models based on two alternative mechanisms for the anomalous pressure scaling, namely: (1) departures at the single-contact level from the hertzian contact, due to point-like or conical asphericity; (2) variation in the number density of hertzian contacts, due to buckling of particle chains. Both mechanisms result in p½pressure scaling at low pressure and both exhibit a high-pressure transition to p½ scaling at a characteristic transition pressure p*. For assemblages of nearly equal spheres, a non-hertzian contact model for mechanism (1) and percolation-type model for (2) yield estimates of p* of the form p* = cμˆ∝3. Here c is a non-dimensional coefficient depending only on granular-contact geometry, while α ≪ 1 is a small parameter representing spherical imperfections and μˆ is an appropriate elastic modulus of the particles. Then, with R representing particle radius and h a characteristic spherical tolerance or asperity height, it is found that α = (h/R)½ for mechanism (1) as opposed to α = h/R for (2). Limited data from the classic experiments of Duffy & Mindlin on sphere assemblages tend to support mechanism (1), but more exhaustive experiments are called for. In addition to the above analysis of reversible elastic effects, a percolation model of inelastic ‘shake-down’ or consolidation is given. It serves to describe how prolonged mechanical vibration, leading to the replacement of point-like or inactive contacts by stiffer Hertz contacts may change the pressure-scaling behaviour of particulate media. The present analysis suggests that pressure-dependence of elasticity may provide a useful means of characterizing the state of consolidation and stability of dense particulate media.
Effect of BRCA1 and BRCA2 on the Association Between Breast Cancer Risk and Family History (1998)

Among women with a moderate family history of breast cancer, i.e., predicted noncarriers of BRCA1 and/or BRCA2 mutations, family history remains a factor in predicting breast cancer risk. In families with breast and ovarian cancers, the aggregation of these two cancers appears to be explained by BRCA1/BRCA2 mutation-carrier probability.
Relationship among cohesion, adhesion, and bond strength: From multi-scale investigation of asphalt-based composites subjected to laboratory-simulated aging (2019)

Identifying the properties of the bond strength between aggregates and asphalt binders is critical to understand the strength and fracture behavior of asphalt mixture. Some efforts have been made on the effect of aging on the bonding property of the asphalt binder. However, there is no consensus result and the mechanism that drives the change of bonding property remains unclear. The objective of this study is to investigate the influence of aging on the bonding property, and to explain the reason lies behind. To achieve this goal, four neat asphalt binders were treated with short-term aging and long-term aging. The bond strength and the adhesion force were measured by binder bond strength test on a macro scale and atomic force microscope on a micro scale, respectively. Based on the result obtained in this study and previous publications along with the adhesion theories, it is found that a moderate aging contributes to the bond strength while a sever aging does not necessarily improve the bond strength. The change of bond strength under an aging condition can be explained by the cohesion force in asphalt binders and the adhesion force between asphalt binders and aggregates. Based on the results, it can be concluded that the cohesion force increases with aging time as a result of asphaltenes association. The adhesion force increases initially and then decreases, and the wettability is thought to be responsible for the reduction of adhesion force. The adhesion reduction can be observed on the three phases (catana phase, peri phase, para phase) of the asphalt binders, which leads to the adhesion reduction on the whole asphalt binders. These findings help to provide a better understanding of the change of bonding property of asphalt binders during an aging process, which contributes to the improvement of bond strength by enhancing the wettability of each phase in asphalt binders appropriately. The results have practical significance and can help to optimize the materials production process. Keywords: Binder bond strength, Adhesion, Cohesion, Aging, Asphalt binder, Atomic force microscope
Variations in the force applied to flexion tests of the distal limb of horses (1997)

A pressure-sensitive device was developed to measure the force applied to flexion tests of the distal limb of horses. The mean force applied by a group of experienced clinicians was 150 N which results in a moment on the flexed fetlock joint of about 28.5 Nm. The coefficient of variation of the force applied by one experienced clinician was only about 12 per cent, but the coefficient of variation between clinicians was considerably higher (20 per cent), irrespective of whether the clinicians were considered to be experienced or not. The mean force applied by a group of women examiners (114 N) was significantly lower than that applied by the group of male examiners. It is concluded that the flexion test used in the clinical examination of the locomotor system of the horse should be better standardised.
The utilization of casein and amino acids by Streptococcus sanguis P4A7 in continuous culture (1990)

Streptococcus sanguis P4A7 was grown in glucose limited conditions in continuous culture at pH 7.0 in a chemically defined medium containing either free amino acids or casein as the organic nitrogen source. Apart from aspartate and threonine, which were poorly utilized at the higher dilution rates, all amino acids in the free-amino-acid medium were utilized to various extents. At the higher dilution rates, aspartate actually increased in concentration, probably due to deamidation of asparagine. The amino acid most utilized at all dilution rates was arginine, with up to 99% of the amino acid being consumed. Both casein and its alpha s1-casein fraction supported growth at a level only slightly lower than that obtained with the free-amino-acid medium, provided that either cysteine or thioglycollate was present. With the exception of tyrosine, nearly all of the amino acyl residues of alpha s1-casein were utilized to some degree. In general, the higher the concentration of each amino acid in the medium (whether free or as part of alpha s1-casein) the higher the extent of utilization by S. sanguis P4A7. Only 50% of the arginyl residues (0.16 mM) of alpha s1-casein were utilized compared with 99% of free arginine (1.5 mM) under similar conditions, suggesting that only 50% of the alpha s1-casein arginine was accessible to the organism.(ABSTRACT TRUNCATED AT 250 WORDS)
Monolayer-Protected Gold Nanoparticles by the Self-Assembly of Micellar Poly(ethylene oxide)-<i>b</i>-Poly(ε-caprolactone) Block Copolymer (2006)

A study is presented of the preparation of gold nanoparticles incorporated into biodegradable micelles. Poly(ethylene oxide)-b-poly(epsilon-caprolactone) (PEO-b-PCL) copolymer was synthesized by ring-opening polymerization, and the hydroxyl end group of the PCL block was modified with thioctic acid using dicyclohexyl carbodiimide as the coupling reagent. The PEO-b-PCL-thioctate ester (TE) thus obtained was used in a later step to form monolayer protected gold nanoparticles via the thioctate spacer. Gold nanoparticles stabilized with the PEO-b-PCL block (named Au/Block (x/y), where x/y is the mole feed ratio between HAuCl4 and PEO-b-PCL-TE) were prepared and analyzed. Au/Block (1/1), Au/Block (2/1), and Au/Block (3/1) nanoparticles were found to form stable dispersions in the organic solvents commonly used to dissolve the unlabeled block copolymer. The average diameter of the nanoparticles was determined by transmission electron microscopy (TEM) and found to be 6+/-2 nm. Au/Block (4/1) nanoparticle dispersions in organic solvents, on the other hand, were not stable and produced large gold clusters (50-100 nm). Cluster formation was attributed to the low grafting density of the block copolymer, which facilitates agglomeration. For Au/Block (12/1), along the same trend, only an insoluble product was isolated. Micelles in water were prepared by the slow addition of the dilute Au/Block solution in dimethylformamide into a large excess of water with vigorous stirring. Au/Block (1/1) and Au/Block (2/1) formed nanosized structures of 5-7 nm. TEM images of stained Au/Block (1/1) micelles, made in water, clearly showed the formation of core-shell structures. Au/Block (3/1) micelles, on the other hand, were not stable and large agglomerates a few microns in size were observed. The study focuses on the synthesis, characterization, and aggregation behavior of gold-loaded PEO-b-PCL block copolymer micelles, a potential system for drug delivery in conjunction with tissue and subcellular localization studies.
Endothelin-1 Is Increased in the Breath Condensate of Patients with Non-Small-Cell Lung Cancer (2004)

These findings suggest that the measurement of ET-1 in the breath condensate of patients with NSCLC could be proposed as a marker for early detection of NSCLC as well as for monitoring reduction or progression of the neoplasm in the follow-up of treated patients.
A Trellis-Structured Neural Network (1987)

We have developed a neural network which consists of cooperatively interconnected Grossberg on-center off-surround subnets and which can be used to optimize a function related to the log likelihood function for decoding convolutional codes or more general FIR signal deconvolution problems. Connections in the network are confined to neighboring subnets, and it is representative of the types of networks which lend themselves to VLSI implementation. Analytical and experimental results for convergence and stability of the network have been found. The structure of the network can be used for distributed representation of data items while allowing for fault tolerance and replacement of faulty units.
Impairment of Tubular Secretion of Urate in Renal Transplant Patients on Cyclosporine (1995)

The prevalence of hyperuricemia was investigated in 214 kidney allograft recipients, 81 were on azathioprine and steroids and 133 on cyclosprine (CyA) and low-dose steroids or on triple therapy. All had stable renal function, serum creatinine < 2.5 mg/dl, and a follow-up between 12 and 120 months. At the time of the study, blood and urine samples were obtained to perform tests of renal function. The renal handling of urate was evaluated by a combined pyrazinamide and probenecid test in 35 selected patients (12 normouricemic on azathioprine, 9 normouricemic on CyA and 14 hyperuricemic on CyA). The prevalence of hyperuricemia was higher in the group of patients on CyA (19.7 vs. 66.9%, p < 0.001), as well as the concentration of serum urate (6.1 +/- 1.9 vs. 7.6 +/- 1.7, p < 0.001), and serum creatinine (1.2 +/- 0.3 vs. 1.4 +/- 0.4, p < 0.001). In patients on CyA, multivariate analysis showed that the most important predictive variables of hyperuricemia were: serum creatinine, FEurate, diuretic use and CyA blood levels (r = 0.73, p < 0.0001). Thirteen patients on CyA (9.9%) had at least one episode of gouty arthritis. Those patients were older than the hyperuricemic patients without gout (45.7 +/- 6.7 vs. 37.1 +/- 13.5 years, p < 0.01), had worse renal function (serum creatinine 1.9 +/- 0.4 vs. 1.5 +/- 0.4 mg/dl, p < 0.01), and higher prevalence of hypertension (100 vs. 63.1%, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
N‐linked sialyated sugar receptors support haematopoietic cell‐osteoblast adhesions (2004)

Haematopoietic progenitor cells proliferate and develop predominantly when they adhere to bone marrow stromal cells such as osteoblasts. Therefore, changes in adhesion may be a common mechanism by which stem cells survive, mature and properly traffic between the bone marrow and the circulation. To characterize these adhesion molecules, we reduced the bone marrow cavity to a simple adhesion assay between KG1a (a CD34+ haematopoietic cell line) and osteosarcoma monolayers (MG-63 or SaOS-2). The data demonstrated that adhesion was mediated by cell-to-cell rather than cell-to-matrix contact, was sensitive to trypsin, calcium chelators and glycosylation inhibitors. Selective pretreatment attributed the constitutive binding to N-linked glycans on KG1a. When carboprocessing was inhibited later at the high mannose intermediate (via deoxymannojirimycin), adhesion was retained. Surprisingly, binding of KG1a to SaOS-2 increased past constitutive levels as doses of tunicamycin or deoxymannojirimycin dropped. Selective pretreatment suggested that this 'inducible' binding resides with molecule(s) on SaOS-2. If the terminal sialic acid was digested (via neuraminidase), this induced response was duplicated. These data, verified in primary cells, suggest that the initial tethering between blood and bone cells in this model is probably due to heavily glycosylated, rapidly processed protein(s) on both cell types.
Webcam clip art (2009)

Webcams placed all over the world observe and record the visual appearance of a variety of outdoor scenes over long periods of time. The recorded time-lapse image sequences cover a wide range of illumination and weather conditions -- a vast untapped resource for creating visual realism. In this work, we propose to use a large repository of webcams as a "clip art" library from which users may transfer scene appearance (objects, scene backdrops, outdoor illumination) into their own time-lapse sequences or even single photographs. The goal is to combine the recent ideas from data-driven appearance transfer techniques with a general and theoretically-grounded physically-based illumination model. To accomplish this, the paper presents three main research contributions: 1) a new, high-quality outdoor webcam database that has been calibrated radiometrically and geometrically; 2) a novel approach for matching illuminations across different scenes based on the estimation of the properties of natural illuminants (sun, sky, weather and clouds), the camera geometry, and illumination-dependent scene features; 3) a new algorithm for generating physically plausible high dynamic range environment maps for each frame in a webcam sequence.
