Monte Carlo simulation of phase separation during thin-film codeposition (1993)

The results of Monte Carlo simulation of phase separation during binary film coevaporation are presented for a range of deposition conditions. The model employed assumes that phase separation occurs through surface interdiffusion during deposition, while the bulk of the film remains frozen. Simulations were performed on A-B alloy films having compositions of 10 and 50 vol % solute. For both film compositions, the lateral scale of the domains at the film surface evolves to a steady-state size during deposition. A power-law dependence of the steady-state domain size on the inverse deposition rate is obtained. Simulation microstructures at 50 vol % compare favorably with those obtained in a previous experimental study of phase separation during coevaporation of Al-Ge films of the same composition. Results of simulations performed at 10 vol % are compared with the predictions of a theoretical model based on the above assumptions. The power-law exponent obtained from simulations at 10 vol % is different than that predicted by the theoretical model. The reasons for this difference are discussed.
Modified Forms of Human Growth Hormone with Increased Biological Activities (1974)

A proteolytically modified form of human growth hormone, isolated from a pituitary extract, had a growth promoting potency of 6.9 IU/mg in the tibial line assay. The prolactin activity of the material, measured by the crop sac assay, was 14.5 IU/mg. Peptide mapping indicated that residues 135–146 were missing from the large disulfide loop of the protein. Data are presented also for two other modified forms of the hormone. One lacked residues 135–140; the other was missing residues 135–145 together with a number of amino acids COOH-terminal to the cleavages. These latter two forms also showed a marked increase in prolactin activity and some potentiation of growth stimulating ability. All three forms were indistinguishable from intact growth hormone by radioimmunoassay and did not react with antiserum to human prolactin. These results indicate that the most active form of human growth hormone, as measured by the tibial line and crop sac assays, is not the intact hormone. (Endocrinology 94: 883, 1974)

Nature of mixed iron and aluminium gels as affected by Fe/Al molar ratio, pH and citrate (1998)

Abstract The nature and mineralogy of mixed Al and Fe(III) gels (initial Fe/Al molar ratios (Ri) of 1.0 and 2.5) formed at pH values ranging from 4.0 to 10.0, both in the presence and absence of citric acid (citrate/Fe + AI molar ratio (Rcit) of 0.01 and 0.1) and aged for a long period at room temperature and at 50°C have been studied. The complexes showed considerable differences in the mineralogy of the precipitation products. The samples formed at Ri = 1.0 contained ferrihydrite at pH 4.0, ferrihydrite + gibbsite at pH 5.0-7.0, and hematite + Al(OH) 3 polymorphs + ferrihydrite at pH 9.0-10.0. The samples formed at Ri = 2.5 had greater quantities of poorly crystallized ferrihydrite. Large amounts of Fe+Al (25-82%) were solubilized from the samples aged for 60 days at 50°C by ammonium oxalate. The addition of increasing concentrations of citrate to the gel suspensions containing equimolar amounts of Fe and AI strongly inhibited the formation of Al(OH) 3 polymorphs both at pH 5.0 or 8.5 by promoting the formation of short-range ordered materials. Citrate added initially to Fe-Al solutions (R*cit = 0.1) completely inhibited formation of crystals even after 135 days at 50°C.
Evidence Supporting the Use of Recombinant Activated Factor VII in Congenital Bleeding Disorders (2011)

Recombinant activated factor VII ([rFVIIa] NovoSeven) was introduced in 1996 for the treatment of haemophilia patients with inhibitors (HPIs) to factor VIII or IX. This article reviews the evidence for the use of rFVIIa in congenital bleeding disorders. English-language databases were searched in September 2009 for reports of randomised controlled trials (RCTs) evaluating the effect of rFVIIa on haemostasis in congenital bleeding disorders. Eight RCTs comprising 256 HPIs were identified. The evidence for the use of rFVIIa in HPIs in terms of dose, clinical setting, modes of administration, efficacy and adverse events was weak, given the limited number of patients included and the heterogeneity of the RCTs. Overall, the haemostatic efficacy of rFVIIa varied from 25 to 100% in the studies reviewed; &lt;1% of the patients receiving rFVIIa developed a thromboembolic adverse event. The authors suggest that the addition FVIIa therapy to HPIs should be based on the patients ability to generate thrombin and form a clot, rather than being based on weight alone. Assays reflecting thrombin generation, such as whole-blood thrombelastography, have the potential to significantly improve the treatment of these patients.

Noise Makers Need to Know Where to be Silent &#150; Producing Schedules That Find Bugs (2006)

A noise maker is a tool that seeds a concurrent program with conditional synchronization primitives, such as yield(), for the purpose of increasing the likelihood that a bug manifest itself. We introduce a novel fault model that classifies locations as "good", "neutral", or "bad," based on the effect of a thread switch at the location. Using the model, we explore the terms under which an efficient search for real-life concurrent bugs can be conducted. We accordingly justify the use of probabilistic algorithms for this search and gain a deeper insight of the work done so far on noise- making. We validate our approach by experimenting with a set of programs taken from publicly available multi-threaded benchmarks. Our empirical evidence demonstrates that real-life behavior is similar to one derived from the model.

Hurdles to Cardioprotection in the Critically Ill (2019)

Cardiovascular disease is the largest contributor to worldwide mortality, and the deleterious impact of heart failure (HF) is projected to grow exponentially in the future. As heart transplantation (HTx) is the only effective treatment for end-stage HF, development of mechanical circulatory support (MCS) technology has unveiled additional therapeutic options for refractory cardiac disease. Unfortunately, despite both MCS and HTx being quintessential treatments for significant cardiac impairment, associated morbidity and mortality remain high. MCS technology continues to evolve, but is associated with numerous disturbances to cardiac function (e.g., oxidative damage, arrhythmias). Following MCS intervention, HTx is frequently the destination option for survival of critically ill cardiac patients. While effective, donor hearts are scarce, thus limiting HTx to few qualifying patients, and HTx remains correlated with substantial post-HTx complications. While MCS and HTx are vital to survival of critically ill cardiac patients, cardioprotective strategies to improve outcomes from these treatments are highly desirable. Accordingly, this review summarizes the current status of MCS and HTx in the clinic, and the associated cardiac complications inherent to these treatments. Furthermore, we detail current research being undertaken to improve cardiac outcomes following MCS/HTx, and important considerations for reducing the significant morbidity and mortality associated with these necessary treatment strategies.
Structural Evidence That the Polymerization Rate Dictates Order and Intrinsic Strain Generation in Photocured Methacrylate Biomedical Polymers (2019)

The influence of reaction rate on the evolving polymer structure of photo-activated dimethacrylate biomedical resins was investigated using neutron and in situ synchrotron X-ray scattering with simultaneous Fourier-transform-near-infrared spectroscopy. Previous studies have correlated the degree of reactive group conversion with mechanical properties, but the impact of polymerization rate on the resultant polymer structure is unknown. Here, we demonstrate that the medium-range structural order at the functional end groups of these materials is dependent on the reaction rate. Accelerating polymerization increases correlation lengths in the methacrylate end groups but reduces the medium-range structural order per converted vinyl bond when compared with more slowly polymerized systems. At faster rates of polymerization, the conformation of atoms at the reacting end group can become fixed into the polymer structure at the onset of autodeceleration, storing residual strain. Neutron scattering confirms that the structural differences observed are reproduced at longer length scales. This effect is not as prominent in systems polymerized at slower rates despite similar final degrees of reactive group conversion. Results suggest that current interpretations of these materials, which extrapolate mechanical properties from conversion, may be incomplete. Accelerating polymerization can introduce structural differences, which will dictate residual strain and may ultimately explain the discrepancies in the predictive modeling of the mechanical behavior of these materials using conventional techniques.
Accurate, Dense, and Robust Multi-View Stereopsis (2007)

This paper proposes a novel algorithm for calibrated multi-view stereopsis that outputs a (quasi) dense set of rectangular patches covering the surfaces visible in the input images. This algorithm does not require any initialization in the form of a bounding volume, and it detects and discards automatically outliers and obstacles. It does not perform any smoothing across nearby features, yet is currently the top performer in terms of both coverage and accuracy for four of the six benchmark datasets presented in [20]. The keys to its performance are effective techniques for enforcing local photometric consistency and global visibility constraints. Stereopsis is implemented as a match, expand, and filter procedure, starting from a sparse set of matched keypoints, and repeatedly expanding these to nearby pixel correspondences before using visibility constraints to filter away false matches. A simple but effective method for turning the resulting patch model into a mesh appropriate for image-based modeling is also presented. The proposed approach is demonstrated on various datasets including objects with fine surface details, deep concavities, and thin structures, outdoor scenes observed from a restricted set of viewpoints, and "crowded" scenes where moving obstacles appear in different places in multiple images of a static structure of interest.
Detuning effects in parametric amplifiers (1965)

Some detuning effects in parametric amplifiers have been observed when the pump frequency is above and below the optimum value. A possible explanation of these effects is suggested.
Effects of vitamin A deficiency on cell proliferation and morphology of trachea of the hamster (1990)

Regulation by vitamin A of cell proliferation and differentiation of epithelial tissues is well-established. Deficiency of vitamin A in experimental animals leads to the development of hyperplasia and squamous metaplasia. The objective of the present study was to examine, for young hamsters, the effects of variable levels of the vitamin in the liver and trachea, on cell proliferation and morphology of tracheal epithelium and on body weights. Newly born litters were maintained on vitamin A-supplemented and vitamin A-deficient diets, and various parameters were examined at different ages. Retinol and retinyl palmitate levels were determined by high performance liquid chromatography. For animals on the supplemented diet, concentrations of liver retinyl palmitate and retinol increased progressively with age, reaching highest levels of approximately 84 and 1.9 micrograms g liver, respectively, at 28 d. In contrast, in animals on the vitamin A-deficient diet, the retinyl palmitate and retinol levels decreased progressively, reaching the lowest levels of approximately 0.32 and 0.09 micrograms/g, respectively. No significant reduction in retinol was observed in the trachea of animals maintained on the deficient diet for at least 20 d: their tracheas were depleted of retinol at 28 d. No vitamin A-associated differences were, however, observed in the labelling indices, growth fraction or in the morphology of the tracheal epithelium. Both the control and vitamin A-deficient animals gained weight progressively until 36 d of age, although the weight of animals in the latter group remained below those in the former group. These results show that mild-to-severe deficiency of vitamin A had no effects on cell proliferation or tracheal morphology of the hamster. The hyperplasia and squamous metaplasia in the trachea occurs only at an extreme vitamin A-deficiency when the tissue levels of the vitamin are depleted.
An approximate square criterion for H.264/AVC intra mode decision (2008)

In this paper, we propose an approximate square criterion for H.264/AVC intra mode decision. The sum of square difference (SSD) criterion achieves the best video quality but takes much high computation due to the square operation. A sum of approximate square difference (SASD) criterion is proposed to maintain the video quality and reduce the computation. By applying the characteristic of the SSD criterion, simulation results show the rate-distortion performance of the SASD criterion is close to that of the SSD method. For the hardware implementation, synthesized results show that the proposed approximate square operation respectively reduces 75% and 61% in the area cost and timing delay than that of the square function.
Bifidobacterium magnum sp. nov., a Large, Acidophilic Bifidobacterium Isolated From Rabbit Feces (1974)

Among 130 strains of bifidobacteria isolated from the feces of rabbits, 26 were distinctive in: (i) having large cellular dimensions (4 to 5 by 17 to 20 μm); (ii) requiring an initial pH of 5.3 to 5.5 for optimum growth; and (iii) having a need for Tween 80 for optimal development in Trypticase-phytone-yeast extract-glucose medium. The other characters of these 26 strains, such as their temperature and oxygen relationships, catalase production, nitrate reduction, end products from glucose fermentation, enzymes of the hexose catabolic pathway, the percent of guanine plus cytosine in the deoxyribonucleic acid (DNA), etc., are similar to those of most bifidobacteria. However, DNA-DNA hybridization studies revealed little or no polynucleotide sequence similarity to any other members of the genus Bifidobacterium. We therefore regard these 26 strains as constituting a new species, for which we propose the name Bifidobacterium magnum. The type strain of this new species is RA3 (= ATCC 27540).
Source separation techniques applied to linear prediction (2000)

The prediction filters are well known models for signal&#13;\nestimation, in communications, control and many others&#13;\nareas. The classical method for deriving linear&#13;\nprediction coding (LPC) filters is often based on the&#13;\nminimization of a mean square error (MSE).&#13;\nConsequently, second order statistics are only required,&#13;\nbut the estimation is only optimal if the residue is&#13;\nindependent and identically distributed (iid) Gaussian.&#13;\nIn this paper, we derive the ML estimate of the&#13;\nprediction filter. Relationships with robust estimation of&#13;\nauto-regressive (AR) processes, with blind&#13;\ndeconvolution and with source separation based on&#13;\nmutual information minimization are then detailed. The&#13;\nalgorithm, based on the minimization of a high-order&#13;\nstatistics criterion, uses on-line estimation of the residue&#13;\nstatistics. Experimental results emphasize on the&#13;\ninterest of this approach.
Distributed Data Mining in Peer-to-Peer Networks (2006)

Peer-to-peer (P2P) networks are gaining popularity in many applications such as file sharing, e-commerce, and social networking, many of which deal with rich, distributed data sources that can benefit from data mining. P2P networks are, in fact, well-suited to distributed data mining (DDM), which deals with the problem of data analysis in environments with distributed data, computing nodes, and users. This article offers an overview of DDM applications and algorithms for P2P environments, focusing particularly on local algorithms that perform data analysis by using computing primitives with limited communication overhead. The authors describe both exact and approximate local P2P data mining algorithms that work in a decentralized and communication-efficient manner

Carbon nanofiber growth in plasma-enhanced chemical vapor deposition (2008)

A theoretical model to describe the plasma-assisted growth of carbon nanofibers (CNFs) is proposed. Using the model, the plasma-related effects on the nanofiber growth parameters, such as the growth rate due to surface and bulk diffusion, the effective carbon flux to the catalyst surface, the characteristic residence time and diffusion length of carbon atoms on the catalyst surface, and the surface coverages, have been studied. The dependence of these parameters on the catalyst surface temperature and ion and etching gas fluxes to the catalyst surface is quantified. The optimum conditions under which a low-temperature plasma environment can benefit the CNF growth are formulated. These results are in good agreement with the available experimental data on CNF growth and can be used for optimizing synthesis of related nanoassemblies in low-temperature plasma-assisted nanofabrication.
Highly Reflective GaN-Based Air-Gap Distributed Bragg Reflectors Fabricated Using AlInN Wet Etching (2009)

We report the fabrication of four-period GaN-based air-gap distributed Bragg reflectors (DBRs) using wet etching of sacrificial AlInN layers. The epitaxial structure grown by Molecular Beam Epitaxy consists of four GaN/Al0.83In0.17N pairs. The sacrificial AlInN layers are selectively under-etched in hot nitric acid to form the air-gap DBR in micro-bridges. Micro-reflectivity spectra exhibiting flat and well defined stop-bands are observed, with peak reflectivities >99% at 590 nm and ∼74% at 400 nm. The full-width half maximum of the widest stop-band is 170 nm in agreement with transmission matrix simulations. Such devices are robust and offer an attractive basis for GaN-based microlasers and microcavities.
RNA-based aptamers as high affinity ligands for tumor cell surface epitopes" (2009)

Structured single-stranded nucleic acids, or aptamers, bind target molecules ranging from small chemical compounds to cells and tissues with high affinity and specificity. Thanks to their unique characteristics (low size, good affinity for the target, no immunogenicity, chemical structures that can be easily modified to improve their in vivo applications), aptamers are perfectly suitable to different areas of biotechnology. Currently, several aptamers are in the clinical pipeline for applications and their functional repertoire has expanded with aptamers as reagents for the targeted delivery. Here we demonstrate that aptamers are efficient tools to bind/inhibit important cell surface epitopes and can be used in clinical diagnosis and therapy. We have developed and validated an in vitro evolution-based approach, named differential whole cell SELEX, to generate a panel of high affinity RNA-based aptamers as ligands for a specific cancer cell phenotype (in two different tumor model systems, glioma and NSCLC). We demonstrate that such an approach can be effective for the generation of functional oligonucleotide ligands that are potentially suitable for diagnostic and therapeutic applications.
