    1983-06-01

    A self-contained, hydraulically operated plunger pump is available to replace conventional equipment in troublesome producing situations. The Soderberg pump from EMI Pump Systems uses an oscillating hydraulic fluid column to energize the plunger, thus eliminating the need for sucker rods and pump jacks or submersible motors. An advantage to the pump's design is that it will stroke only when the pump chamber has been vented of gasses and is filled with well liquids. This reduces energy consumption. Other advantages are discussed. The new pump consists of 4 basic sections including an upper subassembly that contains the pump's intelligence, a chamber to receive well fluids, a plunger and a pressurized nitrogen gas chamber that stores energy for the pump's return stroke.

  2. Copper-phosphorus alloys offer advantages in brazing copper

    1996-05-01

    Copper-phosphorus brazing alloys are used extensively for joining copper, especially refrigeration and air-conditioning copper tubing and electrical conductors. What is the effect of phosphorus when alloyed with copper? The following are some of the major effects: (1) It lowers the melt temperature of copper (a temperature depressant). (2) It increases the fluidity of the copper when in the liquid state. (3) It acts as a deoxidant or a fluxing agent with copper. (4) It lowers the ductility of copper (embrittles). There is a misconception that silver improves the ductility of the copper-phosphorus alloys. In reality, silver added to copper acts in a similar manner as phosphorus. The addition of silver to copper lowers the melt temperature (temperature depressant) and decreases the ductility. Fortunately, the rate and amount at which silver lowers copper ductility is significantly less than that of phosphorus. Therefore, taking advantage of the temperature depressant property of silver, a Ag-Cu-P alloy can be selected at approximately the same melt temperature as a Cu-P alloy, but at a lower phosphorus content. The lowering of the phosphorus content actually makes the alloy more ductile, not the silver addition. A major advantage of the copper-phosphorus alloys is the self-fluxing characteristic when joining copper to copper. They may also be used with the addition of a paste flux on brass, bronze, and specialized applications on silver, tungsten and molybdenum. Whether it is selection of the proper BCuP alloy or troubleshooting an existing problem, the suggested approach is a review of the desired phosphorus content in the liquid metal and how it is being altered during application. In torch brazing, a slight change in the oxygen-fuel ratio can affect the joint quality or leak tightness.

  3. Combination pharmacotherapy for stopping smoking: what advantages does it offer?

    2010-04-16

    Globally, tobacco kills almost 5 million people around the world annually. Seven first-line pharmacotherapies are currently available and recommended by the United States Public Health Service (USPHS) clinical practice guideline for treating tobacco dependence, all of which have been proven to be effective for increasing tobacco abstinence rates when used as monotherapy. However, not all smokers are able to quit with single-drug therapy. Some smokers may benefit from combination therapy that includes the simultaneous use of different nicotine replacement therapies (NRTs) or medications with different mechanisms of action (e.g. NRT and bupropion). Combination therapy with different types of NRT may provide a therapeutic advantage by increasing serum nicotine concentrations, and combination therapy with different drugs may capitalize on synergy obtained from two different mechanisms of action. However, controversy exists regarding this approach. Available data suggests that combination therapy may increase abstinence rates compared with monotherapy. However, the cost effectiveness of this approach has not been clearly demonstrated.

    The use of heavy charged particles for cancer therapy has the potential for a significant improvement of the therapeutic window compared to standard X-ray treatments. This is due to the improved energy deposition profile, exhibiting a well-defined peak at a depth in target controllable by the initial energy of the beam. Particles heavier than protons in addition show an increase in biological effectiveness. Compared to protons or heavy ions, antiprotons deposit additional annihilation energy, mostly by low energy recoils, resulting in an increase of dose and also adding a component with high biological effectiveness in the target region. The relative magnitude of the physical energy deposition of antiprotons compared to protons was measured at Low Energy Antiproton Ring (LEAR) by A. Sullivan, but no study of the biological effect had been conducted prior to the Antiproton Cell Experiment (AD-4/ACE) experiment at CERN. The special conditions found at CERN present significant challenges, but also offer unique opportunities. 500 ns pulses of antiprotons are extracted from the Antiproton Decelerator (AD) at 500 MeV/c momentum. Biological cell samples are irradiated and clonogenic survival fractions are measured for various doses. To extract biological efficiency, the physical dose deposition is obtained by Monte-Carlo calculations in conjunction with shot-by-shot monitoring of the incoming beam intensity and profile using a silicon pixel detector. Also imaging of the pions resulting from antiproton annihilations in the target using silicon pixel detector technology to determine the actual range in more complex targets with strong variations in material densities was carried out. The feasibility of this technique using a novel arrangement of the detector was demonstrated. This paper describes the ACE experiment and focuses on the different detector activities within the AD-4/ACE collaboration, explaining the experimental set-up, physical and biological methods used

    1997-01-01

    Vasectomy, surgical sterilization for men, is very safe, has few side effects, and results in reported annual pregnancy rates of less than 1%. However, men in only a few countries widely adopt vasectomy as their contraceptive method of choice even though it is safer and easier to perform than female sterilization. Approximately 45 million men worldwide have been vasectomized, largely in China, Thailand, India, Korea, the UK, Canada, and the US. Vasectomy is not available in many developing countries, and even if it is available and men have heard of it, many have the misconception that vasectomy causes weakness and adversely affects male sexual function. When trying to increase the access, acceptability, and uptake of vasectomy, enough providers must be trained so that their services are readily available, sustained promotional campaigns should encourage method use, and male clinics and services should be available to help men feel comfortable. Competent counseling is essential to success. The myths and facts of vasectomy, the no-scalpel approach, and promotional campaigns are discussed.

    Additive manufacturing (AM) is a broad term encompassing 3D printing and several other varieties of material processing, which involve computer-directed layer-by-layer synthesis of materials. As the popularity of AM increases, so to do expectations of the medical therapies this process may offer. Clinical requirements and limitations of current treatment strategies in bone grafting, spinal arthrodesis, osteochondral injury and treatment of periprosthetic joint infection are discussed. The various approaches to AM are described, and the current state of clinical translation of AM across these orthopedic clinical scenarios is assessed. Finally, we attempt to distinguish between what AM may offer orthopedic surgery from the hype of what has been promised by AM.

  16. A genomic island provides Acidithiobacillus ferrooxidans ATCC 53993 additional copper resistance: a possible competitive advantage.

    PubMed

    Orellana, Luis H; Jerez, Carlos A

    2011-11-01

    There is great interest in understanding how extremophilic biomining bacteria adapt to exceptionally high copper concentrations in their environment. Acidithiobacillus ferrooxidans ATCC 53993 genome possesses the same copper resistance determinants as strain ATCC 23270. However, the former strain contains in its genome a 160-kb genomic island (GI), which is absent in ATCC 23270. This GI contains, amongst other genes, several genes coding for an additional putative copper ATPase and a Cus system. A. ferrooxidans ATCC 53993 showed a much higher resistance to CuSO(4) (>100 mM) than that of strain ATCC 23270 (<25 mM). When a similar number of bacteria from each strain were mixed and allowed to grow in the absence of copper, their respective final numbers remained approximately equal. However, in the presence of copper, there was a clear overgrowth of strain ATCC 53993 compared to ATCC 23270. This behavior is most likely explained by the presence of the additional copper-resistance genes in the GI of strain ATCC 53993. As determined by qRT-PCR, it was demonstrated that these genes are upregulated when A. ferrooxidans ATCC 53993 is grown in the presence of copper and were shown to be functional when expressed in copper-sensitive Escherichia coli mutants. Thus, the reason for resistance to copper of two strains of the same acidophilic microorganism could be determined by slight differences in their genomes, which may not only lead to changes in their capacities to adapt to their environment, but may also help to select the more fit microorganisms for industrial biomining operations.

    The aim of this study was to determine the effect of 10 days of heat acclimation with and without pre-cooling on intermittent sprint exercise performance in the heat. Eight males completed three intermittent cycling sprint protocols before and after 10 days of heat acclimation. Before acclimation, one sprint protocol was conducted in control conditions (21.8 ± 2.2°C, 42.8 ± 6.7% relative humidity) and two sprint protocols in hot, humid conditions (33.3 ± 0.6°C, 52.2 ± 6.8% relative humidity) in a randomized order. One hot, humid condition was preceded by 20 min of thigh pre-cooling with ice packs (-16.2 ± 4.5°C). After heat acclimation, the two hot, humid sprint protocols were repeated. Before heat acclimation, peak power output declined in the heat (P < 0.05) but pre-cooling prevented this. Ten days of heat acclimation reduced resting rectal temperature from 37.8 ± 0.3°C to 37.4 ± 0.3°C (P < 0.01). When acclimated, peak power output increased by ∼2% (P < 0.05, main effect) and no reductions in individual sprint peak power output were observed. Additional pre-cooling offered no further ergogenic effect. Unacclimated athletes competing in the heat should pre-cool to prevent reductions in peak power output, but heat acclimate for an increased peak power output.

  18. Accuracy Maximization Analysis for Sensory-Perceptual Tasks: Computational Improvements, Filter Robustness, and Coding Advantages for Scaled Additive Noise

    PubMed Central

    Burge, Johannes

    2017-01-01

    Accuracy Maximization Analysis (AMA) is a recently developed Bayesian ideal observer method for task-specific dimensionality reduction. Given a training set of proximal stimuli (e.g. retinal images), a response noise model, and a cost function, AMA returns the filters (i.e. receptive fields) that extract the most useful stimulus features for estimating a user-specified latent variable from those stimuli. Here, we first contribute two technical advances that significantly reduce AMA’s compute time: we derive gradients of cost functions for which two popular estimators are appropriate, and we implement a stochastic gradient descent (AMA-SGD) routine for filter learning. Next, we show how the method can be used to simultaneously probe the impact on neural encoding of natural stimulus variability, the prior over the latent variable, noise power, and the choice of cost function. Then, we examine the geometry of AMA’s unique combination of properties that distinguish it from better-known statistical methods. Using binocular disparity estimation as a concrete test case, we develop insights that have general implications for understanding neural encoding and decoding in a broad class of fundamental sensory-perceptual tasks connected to the energy model. Specifically, we find that non-orthogonal (partially redundant) filters with scaled additive noise tend to outperform orthogonal filters with constant additive noise; non-orthogonal filters and scaled additive noise can interact to sculpt noise-induced stimulus encoding uncertainty to match task-irrelevant stimulus variability. Thus, we show that some properties of neural response thought to be biophysical nuisances can confer coding advantages to neural systems. Finally, we speculate that, if repurposed for the problem of neural systems identification, AMA may be able to overcome a fundamental limitation of standard subunit model estimation. As natural stimuli become more widely used in the study of psychophysical and

    2016-01-01

    This study calculated the growing probability of additional offspring with the advantageous reversal allele in an asymmetric sharply-peaked landscape using the decoupled continuous-time mutation-selection model. The growing probability was calculated for various population sizes, N, sequence lengths, L, selective advantages, s, fitness parameters, k and measuring parameters, C. The saturated growing probability in the stochastic region was approximately the effective selective advantage, s*, when C≫1/Ns* and s*≪1. The present study suggests that the growing probability in the stochastic region in the decoupled continuous-time mutation-selection model can be described using the theoretical formula for the growing probability in the Moran two-allele model. The selective advantage ratio, which represents the ratio of the effective selective advantage to the selective advantage, does not depend on the population size, selective advantage, measuring parameter and fitness parameter; instead the selective advantage ratio decreases with the increasing sequence length.

    2008-02-12

    The influence of progesterone on the physicochemical behaviour of the o/w microemulsion consisting of the non-ionic surfactant polyoxyethylene-10-dodecyl ether, tributyrin and water was investigated. Thereby no significant influence could be detected in terms of droplet size, zeta potential, conductivity and pH by progesterone. However the chemical stability of progesterone was insufficient during the storage of 6 months. Therefore, two different polymeric agents, named silicon dioxide and polymeric emulsifier, were added to the progesterone containing microemulsions. These polymers increased the chemical stability of progesterone significantly. Moreover the polymeric additives improved the skin permeation 1.24- and 1.63-fold and decreased the skin retention in relation to the pure microemulsion. The polymer-stabilized progesterone microemulsions are interesting vehicles for skin application of progesterone.

    In recent years, several fluorenylmethoxycarbonyl (Fmoc)-functionalized amino acids and peptides have been used to construct hydrogels, which find a wide range of applications. Although several hydrogels have been prepared from mono Fmoc-functionalized amino acids, herein, we demonstrate the importance of an additional Fmoc-moiety in the hydrogelation of double Fmoc-functionalized L-lysine [Fmoc(Nα)-L-lysine(NεFmoc)-OH, (Fmoc-K(Fmoc))] as a low molecular weight gelator (LMWG). Unlike other Fmoc-functionalized amino acid gelators, Fmoc-K(Fmoc) exhibits pH-controlled ambidextrous gelation (hydrogelation at different pH values as well as organogelation), which is significant among the gelators. Distinct fibrous morphologies were observed for Fmoc-K(Fmoc) hydrogels formed at different pH values, which are different from organogels in which Fmoc-K(Fmoc) showed bundles of long fibers. In both hydrogels and organogels, the self-assembly of Fmoc-K(Fmoc) was driven by aromatic π-π stacking and hydrogen bonding interactions, as evidenced from spectroscopic analyses. Characterization of Fmoc-K(Fmoc) gels using several biophysical methods indicates that Fmoc-K(Fmoc) has several advantages and significant importance as a LMWG. The advantages of Fmoc-K(Fmoc) include pH-controlled ambidextrous gelation, pH stimulus response, high thermal stability (∼100 °C) even at low minimum hydrogelation concentration (0.1 wt%), thixotropic property, high kinetic and mechanical stability, dye removal properties, cell viability to the selected cell type, and as a drug carrier. While single Fmoc-functionalized L-lysine amino acids failed to exhibit gelation under similar experimental conditions, the pH-controlled ambidextrous gelation of Fmoc-K(Fmoc) demonstrates the benefit of a second Fmoc moiety in inducing gelation in a LMWG. We thus strongly believe that the current findings provide a lead to construct or design various new synthetic Fmoc-based LMW organic gelators for several

    Inhibition of dipeptidyl peptidase-IV (DPP-4) enzyme activity has been revealed to protect myocardium from ischemia-reperfusion through enhancing the endogenous glucagon-like peptide-1 (GLP-1) level. However, whether exogenous supply of exendin-4, an analogue of GLP-1, would still offer benefit for protecting myocardial damage from trans-aortic constriction (TAC)-induced hypertrophic cardiomyopathy in preexistence of DPP-4 deficiency (DPP-4D) remained unclear. Male-adult (DPP-4D) rats (n = 32) were randomized into group 1 [sham control (SC)], group 2 (DPP-4D + TAC), group 3 [DPP-4D + TAC + exendin-4 10 µg/day], and group 4 [DPP-4D + TAC + exendin-4 10 µg + exendin-9-39 10 µg/day]. The rats were sacrificed by day 60 after last echocardiographic examination. By day 60 after TAC, left ventricular ejection fraction (LVEF) (%) was highest in group 1 and lowest in group 2, and significantly lower in group 4 than that in group 3 (all p < 0.001). The protein expressions of oxidative stress (oxidized protein, NOX-1, NOX-2), inflammatory (MMP-9, TNF-α, NF-κB), apoptotic (Bax, cleaved caspase 3 and PARP), fibrotic (TGF-β, Smad3), heart failure (BNP, β-MHC), DNA damaged (γ-H2AX) and ischemic stress (p-P38, p-Akt, p53, ATM) biomarkers showed an opposite pattern of LVEF among the four groups (all p < 0.03). Fibrotic area (by Masson’s trichrome, Sirius red), and cellular expressions of DNA-damaged markers (Ki-67+, γ-H2AX+, CD90+/53BP1+) displayed an identical pattern, whereas cellular expressions of angiogenesis (CD31+, α-SMA+) and sarcomere length exhibited an opposite pattern compared to that of oxidative stress among the four groups (all p < 0.001). Take altogether, Exendin-4 effectively suppressed TAC-induced pathological cardiac hypertrophy in DPP-4D rat. PMID:27158369

    2011-03-01

    As electronic devices shrink in size to reduce material costs, device size and weight, thinner material thicknesses are also utilized. Feature sizes are also decreasing, which is pushing manufacturers towards single step laser direct write process as an attractive alternative to conventional, multiple step photolithography processes by eliminating process steps and the cost of chemicals. The fragile nature of these thin materials makes them difficult to machine either mechanically or with conventional nanosecond pulsewidth, Diode Pumped Solids State (DPSS) lasers. Picosecond laser pulses can cut materials with reduced damage regions and selectively remove thin films due to the reduced thermal effects of the shorter pulsewidth. Also, the high repetition rate allows high speed processing for industrial applications. Selective removal of thin films for OLED patterning, silicon solar cells and flat panel displays is discussed, as well as laser cutting of transparent materials with low melting point such as Polyethylene Terephthalate (PET). For many of these thin film applications, where low pulse energy and high repetition rate are required, throughput can be increased by the use of a novel technique to using multiple beams from a single laser source is outlined.

  11. Negotiating for more: the multiple equivalent simultaneous offer.

    PubMed

    Heller, Richard E

    2014-02-01

    Whether a doctor, professional baseball manager, or a politician, having successful negotiation skills is a critical part of being a leader. Building upon prior journal articles on negotiation strategy, the author presents the concept of the multiple equivalent simultaneous offer (MESO). The concept of a MESO is straightforward: as opposed to making a single offer, make multiple offers with several variables. Each offer alters the different variables, such that the end result of each offer is equivalent from the perspective of the party making the offer. Research has found several advantages to the use of MESOs. For example, using MESOs, an offer was more likely to be accepted, and the counterparty was more likely to be satisfied with the negotiated deal. Additional benefits have been documented as well, underscoring why a prepared radiology business leader should understand the theory and practice of MESO.

    Purpose: Early stage peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is rare. The purpose of this study was to evaluate the outcome of treatment as well as the potential role of radiation therapy in PTCL-NOS. Methods and Materials: Thirty-five patients with early stage PTCL-NOS were included. There were 13 patients with stage I disease and 22 with stage II. All patients except 1 received doxorubicin-based chemotherapy alone (n=13) or a combination of chemotherapy and radiation therapy (CMT) (n=21). Results: The 3-year overall survival (OS) and progression-free survival (PFS) rates for the entire group were 41.3% and 25.7%, respectively. The addition of radiation therapy to chemotherapy significantly improved OS and PFS in early stage PTCL-NOS. The 3-year OS and PFS rates were 49.7% and 33.3% for CMT, compared with 23.1% (P=.042) and 15.4% (P=.035) for chemotherapy alone, respectively. The prognosis for patients who achieved a complete response (CR) was significantly better than that observed in those who did not achieve a CR. Conclusions: Despite the aggressive clinical course of early stage PTCL-NOS, additional radiation therapy has a significant impact on outcome. The integration of local radiation therapy into more effective systemic therapies may further improve survival.

    Liu, Zhirong; Huang, Yongqi

    2014-01-01

    The past decade has witnessed great advances in our understanding of protein structure-function relationships in terms of the ubiquitous existence of intrinsically disordered proteins (IDPs) and intrinsically disordered regions (IDRs). The structural disorder of IDPs/IDRs enables them to play essential functions that are complementary to those of ordered proteins. In addition, IDPs/IDRs are persistent in evolution. Therefore, they are expected to possess some advantages over ordered proteins. In this review, we summarize and survey nine possible advantages of IDPs/IDRs: economizing genome/protein resources, overcoming steric restrictions in binding, achieving high specificity with low affinity, increasing binding rate, facilitating posttranslational modifications, enabling flexible linkers, preventing aggregation, providing resistance to non-native conditions, and allowing compatibility with more available sequences. Some potential advantages of IDPs/IDRs are not well understood and require both experimental and theoretical approaches to decipher. The connection with protein design is also briefly discussed.

  17. The SWIR advantage

    NASA Astrophysics Data System (ADS)

    Lane, Richard N.

    1995-09-01

    The advantage of panchromatic imaging at wavelengths between 1.1 - 2.5 micrometer [short-wave infrared (SWIR)] to that of 0.5 - 1.0 micrometer [visible and near wave infrared (NWIR)] is shown by analysis and experiment in this paper. At long ranges and under low visibility conditions, the signal-to-noise ratio and image quality in the SWIR are significantly better than in the NWIR and visible spectral bands. This effect can be utilized to great advantage in airborne reconnaissance to extend the range of coverage and to improve the interpretability of the product. Such improvements apply to ground-based and space borne systems as well. Other system benefits are derived by utilizing SWIR in place of the NWIR wavelength region. Stabilization requirements can be relaxed; larger optical fabrication, alignment, environmental and boundary layer wavefront error can be tolerated; and less degradation occurs due to atmospheric turbulence and dispersion error. SWIR systems can be fabricated with some of the same optical materials available as in the NWIR and visible systems. All these effects lead to a simpler, less-expensive, and more capable imaging system that together comprise the SWIR Advantage.

    What differentiates truly great corporate strategies from the merely adequate? How can executives at the corporate level create tangible advantage for their businesses that makes the whole more than the sum of the parts? This article presents a comprehensive framework for value creation in the multibusiness company. It addresses the most fundamental questions of corporate strategy: What businesses should a company be in? How should it coordinate activities across businesses? What role should the corporate office play? How should the corporation measure and control performance? Through detailed case studies of Tyco International, Sharp, the Newell Company, and Saatchi and Saatchi, the authors demonstrate that the answers to all those questions are driven largely by the nature of a company's special resources--its assets, skills, and capabilities. These range along a continuum from the highly specialized at one end to the very general at the other. A corporation's location on the continuum constrains the set of businesses it should compete in and limits its choices about the design of its organization. Applying the framework, the authors point out the common mistakes that result from misaligned corporate strategies. Companies mistakenly enter businesses based on similarities in products rather than the resources that contribute to competitive advantage in each business. Instead of tailoring organizational structures and systems to the needs of a particular strategy, they create plain-vanilla corporate offices and infrastructures. The company examples demonstrate that one size does not fit all. One can find great corporate strategies all along the continuum.

  2. Iron-based phosphate binders: do they offer advantages over currently available phosphate binders?

    Negri, Armando Luis; Ureña Torres, Pablo Antonio

    2015-01-01

    Increased cardiovascular morbidity and mortality has been associated with the hyperphosphatemia seen in patients with end-stage chronic kidney disease (CKD). Oral phosphate binders are prescribed in these patients to prevent intestinal absorption of dietary phosphate and reduce serum phosphate. In prospective observational cohorts they have shown to decrease all-cause and cardiovascular mortality risk. Different problems have been associated with currently available phosphate binders as positive calcium balance and impaired outcomes with calcium-based phosphate binders or increased costs with non-calcium-based phosphate binders. Iron-based phosphate binders represent a new class of phosphate binders. Several iron-based phosphate binders have undergone testing in clinical trials. Ferric citrate (JTT-751) and sucroferric oxyhydroxide (PA21) are the two iron-based binders that have passed to the clinical field after being found safe and effective in decreasing serum phosphate. Iron from ferric citrate is partially absorbed compared to sucroferric oxyhydroxide. Ferric citrate usage could result in an important reduction in erythropoiesis-stimulating agent (ESA) and IV iron usage, resulting in significant cost savings. Sucroferric oxyhydroxide was effective in lowering serum phosphorus in dialysis patients with similar efficacy to sevelamer carbonate, but with lower pill burden, and better adherence. Ferric citrate may be more suited for the treatment of chronic hyperphosphatemia in CKD patients requiring iron supplements but its use may have been hampered by potential aluminum overload, as citrate facilitates its absorption; sucroferric oxyhydroxide may be more suited for hyperphosphatemic CKD patients not requiring iron supplementation, with low pill burden.

  3. How Successful Is Medicare Advantage?

    PubMed Central

    Newhouse, Joseph P; McGuire, Thomas G

    2014-01-01

    Context Medicare Part C, or Medicare Advantage (MA), now almost 30 years old, has generally been viewed as a policy disappointment. Enrollment has vacillated but has never come close to the penetration of managed care plans in the commercial insurance market or in Medicaid, and because of payment policy decisions and selection, the MA program is viewed as having added to cost rather than saving funds for the Medicare program. Recent changes in Medicare policy, including improved risk adjustment, however, may have changed this picture. Methods This article summarizes findings from our group's work evaluating MA's recent performance and investigating payment options for improving its performance even more. We studied the behavior of both beneficiaries and plans, as well as the effects of Medicare policy. Findings Beneficiaries make “mistakes” in their choice of MA plan options that can be explained by behavioral economics. Few beneficiaries make an active choice after they enroll in Medicare. The high prevalence of “zero-premium” plans signals inefficiency in plan design and in the market's functioning. That is, Medicare premium policies interfere with economically efficient choices. The adverse selection problem, in which healthier, lower-cost beneficiaries tend to join MA, appears much diminished. The available measures, while limited, suggest that, on average, MA plans offer care of equal or higher quality and for less cost than traditional Medicare (TM). In counties, greater MA penetration appears to improve TM's performance. Conclusions Medicare policies regarding lock-in provisions and risk adjustment that were adopted in the mid-2000s have mitigated the adverse selection problem previously plaguing MA. On average, MA plans appear to offer higher value than TM, and positive spillovers from MA into TM imply that reimbursement should not necessarily be neutral. Policy changes in Medicare that reform the way that beneficiaries are charged for MA plan

    2015-01-01

    An advantage of first mention—that is, faster access to participants mentioned first in a sentence—has previously been demonstrated only in English. We report three experiments demonstrating that the advantage of first mention occurs also in Spanish sentences, regardless of whether the first-mentioned participants are syntactic subjects, and regardless, too, of whether they are proper names or inanimate objects. Because greater word-order flexibility is allowed in Spanish than in English (e.g., nonpassive object-verb-subject constructions exist in Spanish), these findings provide additional evidence that the advantage of first mention is a general cognitive phenomenon.

    In the current research, screen name was employed to explore the possible cognitive advantage for self-related online material. The results showed that one’s own screen name and real name were detected faster than famous names in both visual search and discrimination tasks. In comparison, there was no difference in visual search speed for the two kinds of self-related names. These findings extend self-advantage from the physical world to the virtual online environment and confirm its robustness. In addition, the present findings also suggest that familiarity might not be the determining factor for self-advantage. PMID:26461490

  9. Hollow Retroreflectors Offer Solid Benefits

    2001-01-01

    A technician who lead a successful team of scientists, engineers, and other technicians in the design, fabrication, and characterization of cryogenic retroreflectors for the NASA Cassini/Composite Infrared Spectrometer (CIRS) mission to Saturn, developed a hollow retroreflector technology while working at NASA Goddard Space Flight Center. With 16 years of NASA experience, the technician teamed up with another NASA colleague and formed PROSystems, Inc., of Sharpsburg, Maryland, to provide the optics community with an alternative source for precision hollow retroreflectors. The company's hollow retroreflectors are front surface glass substrates assembled to provide many advantages over existing hollow retroreflectors and solid glass retroreflectors. Previous to this new technology, some companies chose not to use hollow retroreflectors due to large seam widths and loss of signal. The "tongue and groove" facet design of PROSystems's retroreflector allows for an extremely small seam width of .001 inches. Feedback from users is very positive regarding this characteristic. Most of PROSystems's primary customers mount the hollow retroreflectors in chrome steel balls for laser tracker targets in applications such as automobile manufacturing and spacecraft assembly.

  10. Medicare Advantage: options for standardizing benefits and information to improve consumer choice.

    O'Brien, Ellen; Hoadley, Jack

    2008-04-01

    The Medicare Advantage (MA) program offers beneficiaries a choice of private health plans as alternatives to the traditional fee-for-service Medicare program. MA plans potentially provide additional value, but as plan choices have proliferated, consumers contemplating their options have had difficulty understanding how they differ. Through "standardization" more consistent types of information and a limited number of dimensions along which plans vary--MA plans could reduce complexity and improve beneficiaries' ability to make informed choices. Such standardization steps would offer more meaningful variation in the health coverage options available to beneficiaries, Medicare officials and their community partners would find it far easier to educate beneficiaries about their health plan choices, and beneficiaries would better understand what they were buying. Standardization might also strengthen the ability of the market-based Medicare Advantage program to incorporate beneficiary preferences.

    Compared to traditional research methods, using the Internet to conduct research offers a number of advantages to the researcher, which include increased access to sensitive issues and vulnerable / hidden populations; decreased data entry time requirements; and enhanced data accuracy. However, Internet research also presents certain challenges to the researcher. In this article, the advantages and challenges of Internet research methods are discussed in four principle issue areas: (a) recruitment, (b) data quality, (c) practicality, and (d) ethics. Nursing researchers can overcome problems related to sampling bias and data truthfulness using creative methods; resolve technical problems through collaboration with other disciplines; and protect participant's privacy, confidentiality and data security by maintaining a high level of vigilance. Once such issues have been satisfactorily addressed, the Internet should open a new window for Taiwan nursing research.

  12. Policy offers protection from harassment

    NASA Astrophysics Data System (ADS)

    McNutt, Marcia

    We face a number of legal and ethical issues in our work as scientists and as AGU members. To uphold the highest ethical standards in our professional activities, the Council has adopted policies on free access to published material, ethics in publishing, and misconduct in science. But what about guidelines to govern the personal behavior that constitutes harassment, sexual or otherwise?For years the AGU headquarters staff has had a policy that offers protection from harassment and rules for dealing with it, but the membership went without one until 1994. That year the Council adopted a policy that extends to the membership as well as to the staff and the vendors they encounter at meetings. The law only requires a policy to prevent harassment in the workplace, but the Council felt that a harassment policy was particularly important for members because the subtle behavior that can constitute harassment is most likely to occur at events that combine work and social interaction, such as the meetings, conferences, and training seminars that AGU members attend.

  13. Polyimide Foams Offer Superior Insulation

    NASA Technical Reports Server (NTRS)

    2012-01-01

    At Langley Research Center, Erik Weiser and his colleagues in the Advanced Materials and Processing Branch were working with a new substance for fabricating composites for use in supersonic aircraft. The team, however, was experiencing some frustration. Every time they tried to create a solid composite from the polyimide (an advanced polymer) material, it bubbled and foamed. It seemed like the team had reached a dead end in their research - until they had another idea. "We said, This isn t going to work for composites, but maybe we could make a foam out of it," Weiser says. "That was kind of our eureka moment, to see if we could go in a whole other direction. And it worked." Weiser and his colleagues invented a new kind of polyimide foam insulation they named TEEK. The innovation displayed a host of advantages over existing insulation options. Compared to other commercial foams, Weiser explains, polyimide foams perform well across a broad range of temperatures, noting that the NASA TEEK foams provide effective structural insulation up to 600 F and down to cryogenic temperatures. The foam does not burn or off-gas toxic fumes, and even at -423 F - the temperature of liquid hydrogen - the material stays flexible. The inventors could produce the TEEK foam at a range of densities, from 0.5 pounds per cubic foot up to 20 pounds per cubic foot, making the foam ideal for a range of applications, including as insulation for reusable launch vehicles and for cryogenic tanks and lines. They also developed a unique, friable balloon format for manufacturing the foam, producing it as hollow microspheres that allowed the foam to be molded and then cured into any desired shape - perfect for insulating pipes of different sizes and configurations. The team s originally unplanned invention won an "R&D 100" award, and a later form of the foam, called LaRC FPF-44 (Spinoff 2009), was named "NASA Invention of the Year" in 2007.

    2008-01-01

    Robot Systems Technology Branch engineers at Johnson Space Center created the remotely controlled Robonaut for use as an additional "set of hands" in extravehicular activities (EVAs) and to allow exploration of environments that would be too dangerous or difficult for humans. One of the problems Robonaut developers encountered was that the robot s interface offered an extremely limited field of vision. Johnson robotics engineer, Darby Magruder, explained that the 40-degree field-of-view (FOV) in initial robotic prototypes provided very narrow tunnel vision, which posed difficulties for Robonaut operators trying to see the robot s surroundings. Because of the narrow FOV, NASA decided to reach out to the private sector for assistance. In addition to a wider FOV, NASA also desired higher resolution in a head-mounted display (HMD) with the added ability to capture and display video.

    Evolutionary computation is becoming a common technique for solving difficult, real-world problems in industry, medicine, and defense. This paper reviews some of the practical advantages to using evolutionary algorithms as compared with classic methods of optimization or artificial intelligence. Specific advantages include the flexibility of the procedures, as well as their ability to self-adapt the search for optimum solutions on the fly. As desktop computers increase in speed, the application of evolutionary algorithms will become routine.

  18. Systems neuroscience in Drosophila: Conceptual and technical advantages.

    PubMed

    Kazama, H

    2015-06-18

    The fruit fly Drosophila melanogaster is ideally suited for investigating the neural circuit basis of behavior. Due to the simplicity and genetic tractability of the fly brain, neurons and circuits are identifiable across animals. Additionally, a large set of transgenic lines has been developed with the aim of specifically labeling small subsets of neurons and manipulating them in sophisticated ways. Electrophysiology and imaging can be applied in behaving individuals to examine the computations performed by each neuron, and even the entire population of relevant neurons in a particular region, because of the small size of the brain. Moreover, a rich repertoire of behaviors that can be studied is expanding to include those requiring cognitive abilities. Thus, the fly brain is an attractive system in which to explore both computations and mechanisms underlying behavior at levels spanning from genes through neurons to circuits. This review summarizes the advantages Drosophila offers in achieving this objective. A recent neurophysiology study on olfactory behavior is also introduced to demonstrate the effectiveness of these advantages.

  19. Home advantage in Greek football.

    Armatas, Vasilis; Pollard, Richard

    2014-01-01

    Home advantage as it relates to team performance at football was examined in Superleague Greece using nine seasons of game-by-game performance data, a total of 2160 matches. After adjusting for team ability and annual fluctuations in home advantage, there were significant differences between teams. Previous findings regarding the role of territorial protection were strengthened by the fact that home advantage was above average for the team from Xanthi (P =0.015), while lower for teams from the capital city Athens (P =0.008). There were differences between home and away teams in the incidence of most of the 13 within-game match variables, but associated effect sizes were only moderate. In contrast, outcome ratios derived from these variables, and measuring shot success, had negligible effect sizes. This supported a previous finding that home and away teams differed in the incidence of on-the-ball behaviours, but not in their outcomes. By far the most important predictor of home advantage, as measured by goal difference, was the difference between home and away teams in terms of kicked shots from inside the penalty area. Other types of shots had little effect on the final score. The absence of a running track between spectators and the playing field was also a significant predictor of goal difference, worth an average of 0.102 goals per game to the home team. Travel distance did not affect home advantage.

  20. The Star Rating System and Medicare Advantage Plans.

    PubMed

    Sprague, Lisa

    2015-05-05

    With nearly 30 percent of Medicare beneficiaries opting to enroll in Medicare Advantage (MA) plans instead of fee-for-service Medicare, it's safe to say the MA program is quite popular. The Centers for Medicare & Medicaid Services (CMS) administers a Star Ratings program for MA plans, which offers measures of quality and service among the plans that are used not only to help beneficiaries choose plans but also to award additional payments to plans that meet high standards. These additional payments, in turn, are used by plans to provide additional benefits to beneficiaries or to reduce cost sharing--added features that are likely to factor into beneficiaries' choice of MA plans. The Star Ratings program is also meant to drive improvements in the quality of plans, and this secondary effort seems to have been successful. Despite this success, issues with the Star Ratings system remain, including: how performance metrics are developed, chosen, and maintained; how differences among beneficiary populations (particularly with regard to the dually eligible and those receiving low-income subsidies) should be recognized; and the extent to which health plans can control the variables on which they are being measured. Because the Star Ratings approach has been extended to providers of health care as well--hospitals, nursing homes, and dialysis facilities--these issues are worth exploring as CMS fine-tunes its methods of measurement.

We assume that the genomes of the replicating organisms are two-chromosomed and diploid, and that the fitness is determined by the number of chromosomes that are identical to a given master sequence. We also assume that there is a cost to sexual replication, given by a characteristic time τseek during which haploid cells seek out a mate with which to recombine. If the mating strategy is such that only viable haploids can mate, then when τseek= 0 , it is possible to show that sexual replication will always outcompete asexual replication. However, as τseek increases, sexual replication only becomes advantageous at progressively higher mutation rates. Once the time cost for sex reaches a critical threshold, the selective advantage for sexual replication disappears entirely. The results of this talk suggest that sexual replication is not advantageous in small populations per se, but rather in populations with low replication rates. In this regime, the cost for sex is sufficiently low that the selective advantage obtained through recombination leads to the dominance of the strategy. In fact, at a given replication rate and for a fixed environment volume, sexual replication is selected for in high populations because of the reduced time spent finding a reproductive partner.

    This paper develops a simplified model for sexual reproduction within the quasispecies formalism. The model assumes a diploid genome consisting of two chromosomes, where the fitness is determined by the number of chromosomes that are identical to a given master sequence. We also assume that there is a cost to sexual reproduction, given by a characteristic time τseek during which haploid cells seek out a mate with which to recombine. If the mating strategy is such that only viable haploids can mate, then when τseek=0 , it is possible to show that sexual reproduction will always out compete asexual reproduction. However, as τseek increases, sexual reproduction only becomes advantageous at progressively higher mutation rates. Once the time cost for sex reaches a critical threshold, the selective advantage for sexual reproduction disappears entirely. The results of this paper suggest that sexual reproduction is not advantageous in small populations per se, but rather in populations with low replication rates. In this regime, the cost for sex is sufficiently low that the selective advantage obtained through recombination leads to the dominance of the strategy. In fact, at a given replication rate and for a fixed environment volume, sexual reproduction is selected for in high populations because of the reduced time spent finding a reproductive partner.

    Many managers believe that superior service should play little or no role in competitive strategy; they maintain that service innovations are inherently copiable. However, the author states that this view is too narrow. For a company to achieve a lasting service advantage, it must base a new service on a capability gap that competitors cannot or will not copy.

    Although previous research has shown that making the first offer leads to a distributive advantage in negotiations, the current research explored how the timing of first offers affects the creativity of negotiation agreements. We hypothesized that making the first offer later rather than earlier in the negotiation would facilitate the discovery of creative agreements that better meet the parties' underlying interests. Experiment 1 demonstrated that compared with early first offers, late first offers facilitated creative agreements that better met the parties' underlying interests. Experiments 2a and 2b controlled for the duration of the negotiation and conceptually replicated this effect. The last two studies also demonstrated that the beneficial effect of late first offers was mediated by greater information exchange. Thus, negotiators need to consider the timing of first offers to fully capitalize on the first offer advantage. Implications for our understanding of creativity, motivated information exchange, and timing in negotiations are discussed.

  14. Nonlocal advantage of quantum coherence

    2017-01-01

    A bipartite state is said to be steerable if and only if it does not have a single-system description, i.e., the bipartite state cannot be explained by a local hidden state model. Several steering inequalities have been derived using different local uncertainty relations to verify the ability to control the state of one subsystem by the other party. Here, we derive complementarity relations between coherences measured on mutually unbiased bases using various coherence measures such as the l1-norm, relative entropy, and skew information. Using these relations, we derive conditions under which a nonlocal advantage of quantum coherence can be achieved and the state is steerable. We show that not all steerable states can achieve such an advantage.

  15. Assessing the binocular advantage in aided vision.

    Harrington, Lawrence K; McIntire, John P; Hopper, Darrel G

    2014-09-01

    Advances in microsensors, microprocessors, and microdisplays are creating new opportunities for improving vision in degraded environments through the use of head-mounted displays. Initially, the cutting-edge technology used in these new displays will be expensive. Inevitably, the cost of providing the additional sensor and processing required to support binocularity brings the value of binocularity into question. Several assessments comparing binocular, binocular, and monocular head-mounted displays for aided vision have concluded that the additional performance, if any, provided by binocular head-mounted displays does not justify the cost. The selection of a biocular [corrected] display for use in the F-35 is a current example of this recurring decision process. It is possible that the human binocularity advantage does not carry over to the aided vision application, but more likely the experimental approaches used in the past have been too coarse to measure its subtle but important benefits. Evaluating the value of binocularity in aided vision applications requires an understanding of the characteristics of both human vision and head-mounted displays. With this understanding, the value of binocularity in aided vision can be estimated and experimental evidence can be collected to confirm or reject the presumed binocular advantage, enabling improved decisions in aided vision system design. This paper describes four computational approaches-geometry of stereopsis, modulation transfer function area for stereopsis, probability summation, and binocular summation-that may be useful in quantifying the advantage of binocularity in aided vision.

(3) Health maintenance organization (HMO) enrollment continued to grow in 2013, with over 31% of the rural MA market, while private fee-for-service (PFFS) plan enrollment decreased to less than 10% of market share. (4) Despite recent changes to MA payment, rural MA enrollment continues to increase.

  18. High School Physics Offerings by Socioeconomic Profile

    NASA Astrophysics Data System (ADS)

    2011-12-01

    This fall we have been examining physics classes in U.S. high schools by the principal's assessment of the socioeconomic profile of each school. This month we turn our focus to the distribution of high school physics enrollment across the different types of physics offered. Not only do fewer students take physics at "worse off" schools (see the October issue), but the types of physics courses students take also differs by socioeconomic profile. About 10% of the students taking physics at "worse off" schools take AP and second-year physics; almost 20% of the students at "better off" schools take these courses. At "worse off" schools, a higher proportion of students are enrolled in conceptual courses, including Physics First and regular physics taught using a conceptual textbook. The data we have presented over the last four months suggests that differences in physics taking in high school by blacks and Hispanics are driven, in part, by underlying socioeconomic factors. Other factors, such as the availability of additional seats in physics classes and the ability of teachers to attract students to physics, also impact physics taking. It is unlikely that the racial and ethnic differences in physics taking in high school will decrease unless the underlying factors are addressed.

  19. Travel and the home advantage.

    PubMed

    Pace, A; Carron, A V

    1992-03-01

    The purpose of the present study was to examine the relative contributions of various travel related variables to visiting team success in the National Hockey League. A multiple regression design was used with game outcome as the dependent variable. The independent variables of interest included, as main effects and interactions, number of time zones crossed, direction of travel, distance traveled, preparation/adjustment time, time of season, game number on the road trip, and the home stand. Visiting team success was negatively associated with the interaction of number of time zones crossed and increased preparation time between games, and was positively associated with game number on the road. It was concluded that only a small portion of the variance in the home advantage/visitor disadvantage can be explained by travel related factors.

  20. Taking advantage of natural biodegradation

    SciTech Connect

    Butler, W.A.; Bartlett, C.L.

    1995-12-31

    A chemical manufacturing facility in central New Jersey evaluated alternatives to address low levels of volatile organic compounds (VOCs) in groundwater. Significant natural attenuation of VOCs was observed in groundwater, and is believed to be the result of natural biodegradation, commonly referred to as intrinsic bioremediation. A study consisting of groundwater sampling and analysis, field monitoring, and transport modeling was conducted to evaluate and confirm this phenomenon. The primary conclusion that can be drawn from the study is that observed natural attenuation of VOCs in groundwater is due to natural biodegradation. Based on the concept that natural biodegradation will minimize contaminant migration, bioventing has been implemented to remove the vadose-zone source of VOCs to groundwater. Taking advantage of natural biodegradation has resulted in significant cost savings compared to implementing a conventional groundwater pump-and-treat system, while still protecting human health and the environment.

  1. Advantages of Oscillatory Hydraulic Tomography

    NASA Astrophysics Data System (ADS)

    2012-12-01

    Characterizing the subsurface is significant for most hydrogeologic studies, such as those involving site remediation and groundwater resource explo¬ration. A variety of hydraulic and geophysical methods have been developed to estimate hydraulic conductivity and specific storage. Hydraulic methods based on the analysis of conventional pumping tests allow the estimation of conductivity and storage without need for approximate petrophysical relations, which is an advantage over most geophysical methods that first estimate other properties and then infer values of hydraulic parameters. However, hydraulic methods have the disadvantage that the head-change signal decays with distance from the pumping well and thus becomes difficult to separate from noise except in close proximity to the source. Oscillatory hydraulic tomography (OHT) is an emerging technology to im¬age the subsurface. This method utilizes the idea of imposing sinusoidally varying pressure or discharge signals at several points, collecting head observations at several other points, and then processing these data in a tomographic fashion to estimate conductivity and storage coefficients. After an overview of the methodology, including a description of the most important potential advantages and challenges associated with this approach, two key promising features of the approach will be discussed. First, the signal at an observation point is orthogonal to and thus can be separated from nuisance inputs like head fluctuation from production wells, evapotranspiration, irrigation, and changes in the level of adjacent streams. Second, although the signal amplitude may be weak, one can extract the phase and amplitude of the os¬cillatory signal by collecting measurements over a longer time, thus compensating for the effect of large distance through longer sampling period.

    2009-09-01

    This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to standardized criteria to determine whether they offered to sell psilocybin or psilocybin spores. No attempts were made to procure the products offered for sale in order to ascertain whether the marketed psilocybin was in fact "genuine" or "counterfeit." Of the 800 links examined, 58% led to websites offering to sell psilocybin spores. Additionally, evidence that whole Psilocybe mushrooms are offered for sale online was obtained. Psilocybin and psilocybin spores were found to be widely available for sale over the Internet. Online purchase of psilocybin may facilitate illicit use of this potent psychoactive substance. Additional studies are needed to assess whether websites offering to sell psilocybin and psilocybin spores actually deliver their products as advertised.

  17. Principles and advantages of robotics in urologic surgery.

    PubMed

    Renda, Antonio; Vallancien, Guy

    2003-04-01

    Although the available minimally invasive surgical techniques (ie, laparoscopy) have clear advantages, these procedures continue to cause problems for patients. Surgical tools are limited by set axes of movement, restricting the degree of freedom available to the surgeon. In addition, depth perception is lost with the use of two-dimensional viewing systems. As surgeons view a "virtual" target on a television screen, they are hampered by decreased sensory input and a concurrent loss of dexterity. The development of robotic assistance systems in recent years could be the key to overcoming these difficulties. Using robotic systems, surgeons can experience a more natural and ergonomic surgical "feel." Surgical assistance, dexterity and precision enhancement, systems networking, and image-guided therapy are among the benefits offered by surgical robots. In return, the surgeon gains a shorter learning curve, reduced fatigue, and the opportunity to perform complex procedures that would be difficult using conventional laparoscopy. With the development of image-guided technology, robotic systems will become useful tools for surgical training and simulation. Remote surgery is not a routine procedure, but several teams are working on this and experiencing good results. However, economic concerns are the major drawbacks of these systems; before remote surgery becomes routinely feasible, the clinical benefits must be balanced with high investment and running costs.

  18. Medicare Advantage update: benefits, enrollment, and payments after the ACA.

    PubMed

    Linehan, Kathryn

    2013-07-19

    In 2012, the Medicare program paid private health plans $136 billion to cover about 13 million beneficiaries who received Part A and B benefits through the Medicare Advantage (MA) program rather than traditional fee-for-service (FFS) Medicare. Private plans have been a part of the program since the 1970s. Debate about the policy goals--Should they cost less per beneficiary than FFS Medicare? Should they be available to all beneficiaries? Should they be able to offer additional benefits?--has long accompanied Medicare's private plan option.This debate is reflected in the history of Medicare payment policy,and policy decisions over the years have affected plans' willingness to participate and beneficiaries' enrollment at different periods of the program. Recently, evidence that the Medicare program was paying more per beneficiary in MA relative to what would have been spent under FFS Medicare prompted policymakers to reduce MA payments in the Patient Protection and Affordable Care Act of 2010 (ACA). So far, plans continue to participate in MA and enrollment continues to grow, but payment reductions in 2012 through 2014 have been partially offset by payments made to plans through the quality bonus payment demonstration.This brief contains recent data on plan enrollment, availability, and benefits and discusses MA plan payment policy, including changes to MA payment made in the ACA and their actual and projected effects.

    Purpose. The RUPRI Center for Rural Health Policy Analysis reports annually on rural beneficiary enrollment in Medicare Advantage (MA) plans, noting any trends or new developments evident in the data. These reports are based on data through March of each year, capturing results of open enrollment periods. Key Findings. (1)The number of non-metropolitan beneficiaries enrolled in MA and other prepaid plans increased to 2,189,300 as of March 2016, representing 21.8 percent of all non-metropolitan Medicare beneficiaries compared with 31.5 percent of beneficiaries enrolled in MA and other prepaid plans nationally. (2) While non-metropolitan enrollment continued to increase through March 2016, the annual growth rate slowed to 5.5 percent, compared to 6.8 percent between March 2014 and March 2015. (3) Enrollment in private fee-for-service MA plans continued to decline, both nationally and in non-metropolitan counties, while enrollment in other types of MA plans increased. (4) The states with the highest percentage of non-metropolitan beneficiaries enrolled in MA plans continued to be Minnesota, Hawaii, Pennsylvania, Wisconsin, and New York, ranging from a high of 53.4 percent in Minnesota to 32.6 percent in New York. (5) Non-metropolitan beneficiary enrollment (counts) in MA plans declined in five states: Hawaii, Idaho, Ohio, Washington, and Wyoming.

  20. Evolutionary advantages of adaptive rewarding

    NASA Astrophysics Data System (ADS)

    Szolnoki, Attila; Perc, Matjaž

    2012-09-01

    Our well-being depends on both our personal success and the success of our society. The realization of this fact makes cooperation an essential trait. Experiments have shown that rewards can elevate our readiness to cooperate, but since giving a reward inevitably entails paying a cost for it, the emergence and stability of such behavior remains elusive. Here we show that allowing for the act of rewarding to self-organize in dependence on the success of cooperation creates several evolutionary advantages that instill new ways through which collaborative efforts are promoted. Ranging from indirect territorial battle to the spontaneous emergence and destruction of coexistence, phase diagrams and the underlying spatial patterns reveal fascinatingly rich social dynamics that explain why this costly behavior has evolved and persevered. Comparisons with adaptive punishment, however, uncover an Achilles heel of adaptive rewarding, coming from over-aggression, which in turn hinders optimal utilization of network reciprocity. This may explain why, despite its success, rewarding is not as firmly embedded into our societal organization as punishment.

  1. Advantages and Uses of AMTEC

    NASA Astrophysics Data System (ADS)

    Lodhi, M. A. K.

    2012-10-01

    Static conversion systems are gaining importance in recent times because of newer applications of electricity like in spacecraft, hybrid-electric vehicles, military uses and domestic purposes. Of the many new static energy conversion systems that are being considered, one is the Alkali Metal Thermal Electric Converter (AMTEC). It is a thermally regenerative, electrochemical device for the direct conversion of heat to electrical power. As the name suggests, this system uses an alkali metal in its process. The electrochemical process involved in the working of AMTEC is ionization of alkali metal atoms at the interface of electrode and electrolyte. The electrons produced as a result flow through the external load thus doing work, and finally recombine with the metal ions at the cathode. AMTECs convert the work done during the nearly isothermal expansion of metal vapor to produce a high current and low voltage electron flow. Due to its principle of working it has many inherent advantages over other conventional generators. These will be discussed briefly.

  2. Dendritic Cell Based Vaccines that Utilize Myeloid Rather than Plasmacytoid Cells Offer a Superior Survival Advantage in Malignant Glioma

    2015-01-01

    Dendritic cells (DC) are professional antigen presenting cells (APC) that are traditionally divided into two distinct subsets: myeloid DC (mDCs) and plasmacytoid DC (pDCs). pDCs are known for their ability to secrete large amount of IFN-α. Apart from IFN-α production, pDCs can also process antigen and induce T-cell immunity or tolerance. In several solid tumors, pDCs have been shown to play a critical role in promoting tumor immunosuppression. We investigated the role of pDCs in the process of glioma progression in the syngeneic murine model of glioma. We show that glioma-infiltrating pDCs are the major APC in glioma and are deficient in IFN-α secretion (p < 0.05). pDC depletion leads to increased survival of the mice bearing intracranial tumor by decreasing the number of regulatory T-cells (Treg) and by decreasing the suppressive capabilities of Tregs. We subsequently compared the ability of mDCs and pDCs to generate effective anti-glioma immunity in a GL261-OVA mouse model of glioma. Our data suggest that mature pDCs and mDCs isolated from naïve mice can be effectively activated and loaded with SIINFEKL antigen in vitro. Upon intra-dermal injection in the hind leg, a fraction of both types of DCs migrate to the brain and lymph nodes.. Compared to mice vaccinated with pDC or control mice, mice vaccinated with mDCs generated a robust Th1 type immune response, characterized by high frequency of CD4+Tbet+ T-cells and CD8+Siinfekel+ T-cells. This robust anti-tumor T-cell response resulted in tumor eradication and long-term survival in 60% of the animals (p<0.001). PMID:26026061

    We obtain a general connection between a large quantum advantage in communication complexity and Bell nonlocality. We show that given any protocol offering a sufficiently large quantum advantage in communication complexity, there exists a way of obtaining measurement statistics that violate some Bell inequality. Our main tool is port-based teleportation. If the gap between quantum and classical communication complexity can grow arbitrarily large, the ratio of the quantum value to the classical value of the Bell quantity becomes unbounded with the increase in the number of inputs and outputs.

    Digital PCR (dPCR), a new nucleic acid amplification technology, offers several potential advantages over real-time or quantitative PCR (qPCR), the current workhorse of clinical molecular virology diagnostics. Several studies have demonstrated dPCR assays for human cytomegalovirus or HIV, which give more precise and reproducible results than qPCR assays without sacrificing sensitivity. Here we review the literature comparing dPCR and qPCR performance in viral molecular diagnostic assays and offer perspective on the future of dPCR in clinical virology diagnostics.

  10. Vegetarian diets: what are the advantages?

    PubMed

    Leitzmann, Claus

    2005-01-01

    A growing body of scientific evidence indicates that wholesome vegetarian diets offer distinct advantages compared to diets containing meat and other foods of animal origin. The benefits arise from lower intakes of saturated fat, cholesterol and animal protein as well as higher intakes of complex carbohydrates, dietary fiber, magnesium, folic acid, vitamin C and E, carotenoids and other phytochemicals. Since vegetarians consume widely divergent diets, a differentiation between various types of vegetarian diets is necessary. Indeed, many contradictions and misunderstandings concerning vegetarianism are due to scientific data from studies without this differentiation. In the past, vegetarian diets have been described as being deficient in several nutrients including protein, iron, zinc, calcium, vitamin B12 and A, n-3 fatty acids and iodine. Numerous studies have demonstrated that the observed deficiencies are usually due to poor meal planning. Well-balanced vegetarian diets are appropriate for all stages of the life cycle, including children, adolescents, pregnant and lactating women, the elderly and competitive athletes. In most cases, vegetarian diets are beneficial in the prevention and treatment of certain diseases, such as cardiovascular disease, hypertension, diabetes, cancer, osteoporosis, renal disease and dementia, as well as diverticular disease, gallstones and rheumatoid arthritis. The reasons for choosing a vegetarian diet often go beyond health and well-being and include among others economical, ecological and social concerns. The influences of these aspects of vegetarian diets are the subject of the new field of nutritional ecology that is concerned with sustainable life styles and human development.

    2014-09-01

    In many experimental setups in social-sciences, psychology and economy the subjects are requested to accept or dispense monetary compensation which is usually given in discrete units. Using computer and mathematical modeling we show that in the framework of studying the dynamics of acceptance of proposals in the ultimatum game, the long time dynamics of acceptance of offers in the game are completely different for discrete vs. continuous offers. For discrete values the dynamics follow an exponential behavior. However, for continuous offers the dynamics are described by a power-law. This is shown using an agent based computer simulation as well as by utilizing an analytical solution of a mean-field equation describing the model. These findings have implications to the design and interpretation of socio-economical experiments beyond the ultimatum game.

    1993-11-01

    With each century come new and exciting technologies, but perhaps the most challenging innovations have occurred in the modern era as a result of man's quest to explore the universe. While enormous advancements have occurred during the space age, there still remain significant obstacles in deep space exploration. A practical challenge to exploration is the development of a type of propulsion suitable for deep space endeavors. The development of such a propulsion system would greatly facilitate space research, while providing additional opportunities for other classes of exploration not yet defined. Based upon current research, there exist several possibilities for future propulsion techniques. Some of the most promising research has dealt with antimatter and its usefulness in energy production. The potential of antimatter as an efficient and renewable energy source exists, yet important practical and scientific concerns must be overcome to make this technology feasible. For deep space exploration to be successful, more advanced and powerful propulsion systems need to be devised. Current rocket technology is inadequate to meet these future needs. The authors predict that antimatter propulsion will emerge as the new standard for space exploration. At least the beginnings of this new technology are expected within the next twenty years.

    As recognised by the National Institutes of Health (NIH) Precision Medicine Initiative (PMI), microarray technology currently provides a rapid, inexpensive means of identifying large numbers of known genomic variants or gene transcripts in experimental and clinical settings. However new generation sequencing techniques are now being introduced in many clinical genetic contexts, particularly where novel mutations are involved. While these methods can be valuable for screening a restricted set of genes for known or novel mutations, implementation of whole genome sequencing in clinical practice continues to present challenges. Even very accurate high-throughput methods with small error rates can generate large numbers of false negative or false positive errors due to the high numbers of simultaneous readings. Additional validation is likely to be required for safe use of any such methods in clinical settings. Custom-designed arrays can offer advantages for screening for common, known mutations and, in this context, may currently be better suited for accredited, quality-controlled clinical genetic screening services, as illustrated by their successful application in several large-scale pre-emptive pharmacogenomics programs now underway. Excessive, inappropriate use of next-generation sequencing may waste scarce research funds and other resources. Microarrays presently remain the technology of choice in applications that require fast, cost-effective genome-wide screening of variants of known importance, particularly for large sample sizes. This commentary considers some of the applications where microarrays continue to offer advantages over next-generation sequencing technologies. PMID:27600079

  7. Competitive advantage on a warming planet.

    PubMed

    Lash, Jonathan; Wellington, Fred

    2007-03-01

    Whether you're in a traditional smokestack industry or a "clean" business like investment banking, your company will increasingly feel the effects of climate change. Even people skeptical about global warming's dangers are recognizing that, simply because so many others are concerned, the phenomenon has wide-ranging implications. Investors already are discounting share prices of companies poorly positioned to compete in a warming world. Many businesses face higher raw material and energy costs as more and more governments enact policies placing a cost on emissions. Consumers are taking into account a company's environmental record when making purchasing decisions. There's also a burgeoning market in greenhouse gas emission allowances (the carbon market), with annual trading in these assets valued at tens of billions of dollars. Companies that manage and mitigate their exposure to the risks associated with climate change while seeking new opportunities for profit will generate a competitive advantage over rivals in a carbon-constrained future. This article offers a systematic approach to mapping and responding to climate change risks. According to Jonathan Lash and Fred Wellington of the World Resources Institute, an environmental think tank, the risks can be divided into six categories: regulatory (policies such as new emissions standards), products and technology (the development and marketing of climate-friendly products and services), litigation (lawsuits alleging environmental harm), reputational (how a company's environmental policies affect its brand), supply chain (potentially higher raw material and energy costs), and physical (such as an increase in the incidence of hurricanes). The authors propose a four-step process for responding to climate change risk: Quantify your company's carbon footprint; identify the risks and opportunities you face; adapt your business in response; and do it better than your competitors.

  8. Competitive advantage of PET/MRI.

    PubMed

    Jadvar, Hossein; Colletti, Patrick M

    2014-01-01

    Multimodality imaging has made great strides in the imaging evaluation of patients with a variety of diseases. Positron emission tomography/computed tomography (PET/CT) is now established as the imaging modality of choice in many clinical conditions, particularly in oncology. While the initial development of combined PET/magnetic resonance imaging (PET/MRI) was in the preclinical arena, hybrid PET/MR scanners are now available for clinical use. PET/MRI combines the unique features of MRI including excellent soft tissue contrast, diffusion-weighted imaging, dynamic contrast-enhanced imaging, fMRI and other specialized sequences as well as MR spectroscopy with the quantitative physiologic information that is provided by PET. Most evidence for the potential clinical utility of PET/MRI is based on studies performed with side-by-side comparison or software-fused MRI and PET images. Data on distinctive utility of hybrid PET/MRI are rapidly emerging. There are potential competitive advantages of PET/MRI over PET/CT. In general, PET/MRI may be preferred over PET/CT where the unique features of MRI provide more robust imaging evaluation in certain clinical settings. The exact role and potential utility of simultaneous data acquisition in specific research and clinical settings will need to be defined. It may be that simultaneous PET/MRI will be best suited for clinical situations that are disease-specific, organ-specific, related to diseases of the children or in those patients undergoing repeated imaging for whom cumulative radiation dose must be kept as low as reasonably achievable. PET/MRI also offers interesting opportunities for use of dual modality probes. Upon clear definition of clinical utility, other important and practical issues related to business operational model, clinical workflow and reimbursement will also be resolved.

  12. Family planning offered in local welfare offices.

    PubMed

    1998-04-01

    This article describes expanded access to family planning (FP) services through community welfare offices in Washington state, US. The government aim is to decrease unintended pregnancies and to help families achieve self-sufficiency. The staff must be sensitive and respectful of clients served. The team effort includes contacting clients in other community locations to offer FP education. The approach is characterized as "1-stop shopping" that includes FP, welfare, access to jobs, training, and medical coupons. Preventing unintended pregnancies is cost effective. A state (90%) investment of $40/person for contraceptives is good business compared to $400/person as a 50/50 state/federal investment in prenatal and delivery costs. The program began in 1992, by educating staff members in community services offices (CSOs) about FP issues. In 1994, the program hired registered nurses and nurse practitioners at CSOs to provide FP services. Almost all CSOs now have nurses, and there are 8 full exam clinics. A resource handbook for CSO workers and FP nurses was compiled by state and local FP personnel. CSOs typically assign 1 staff member to FP, usually on a part time basis. Close collaboration between nurses and CSO workers usually involves more creative strategies and outreach projects. For example, in 1 CSO in Washington, the FP worker offers contraceptive counseling, pregnancy tests, and sexually transmitted disease prevention. Contraceptives are provided at a separate time with local private providers or at health department clinics. CSOs continue to provide counseling regardless of referrals to private clinics. The project is growing and forming collaborations with other FP groups. These 1-stop sites offer accessible, familiar, and comfortable services.

    Soares, T.; Pinson, P.; Morais, H.

    2016-09-01

    The increasing penetration of wind generation in power systems to fulfil the ambitious European targets will make wind power producers to play an even more important role in the future power system. Wind power producers are being incentivized to participate in reserve markets to increase their revenue, since currently wind turbine/farm technologies allow them to provide ancillary services. Thus, wind power producers are to develop offering strategies for participation in both energy and reserve markets, accounting for market rules, while ensuring optimal revenue. We consider a proportional offering strategy to optimally decide upon participation in both markets by maximizing expected revenue from day-ahead decisions while accounting for estimated regulation costs for failing to provide the services. An evaluation of considering the same proportional splitting of energy and reserve in both day- ahead and balancing market is performed. A set of numerical examples illustrate the behavior of such strategy. An important conclusion is that the optimal split of the available wind power between energy and reserve strongly depends upon prices and penalties on both market trading floors.

    Creative, dynamic strategies are the ones that identify new and better ways of uniquely offering the target customers what they want or need. A business can achieve competitive advantage if it chooses a marketing strategy that sets the business apart from anyone else. Healthcare services companies have to understand that the customer should be placed in the centre of all specific marketing operations. The brand message should reflect the focus on the patient. Healthcare products and services offered must represent exactly the solutions that customers expect. The touchpoints with the patients must be well mastered in order to convince them to accept the proposed solutions. Healthcare service providers must be capable to look beyond customer's behaviour or product and healthcare service aquisition. This will demand proactive and far–reaching changes, including focusing specifically on customer preference, quality, and technological interfaces; rewiring strategy to find new value from existing and unfamiliar sources; disintegrating and radically reassembling operational processes; and restructuring the organization to accommodate new typess of work and skill.

    Rudolf Keller

    2004-08-10

    In this project, a concept to improve the performance of aluminum production cells by introducing potlining additives was examined and tested. Boron oxide was added to cathode blocks, and titanium was dissolved in the metal pool; this resulted in the formation of titanium diboride and caused the molten aluminum to wet the carbonaceous cathode surface. Such wetting reportedly leads to operational improvements and extended cell life. In addition, boron oxide suppresses cyanide formation. This final report presents and discusses the results of this project. Substantial economic benefits for the practical implementation of the technology are projected, especially for modern cells with graphitized blocks. For example, with an energy savings of about 5% and an increase in pot life from 1500 to 2500 days, a cost savings of $ 0.023 per pound of aluminum produced is projected for a 200 kA pot.

  4. Informal leadership support: an often overlooked competitive advantage.

    Peters, L H; O'Connor, E J

    2001-01-01

    As environmental pressures mount, the advantage of using the same strategies and tactics employed by competitors continues to shrink. An alternative is adapting and applying answers successfully employed in other industries to health care organizations. Working with informal influence leaders to share your change management efforts represents one such example. Informal influence leaders offer an often-overlooked source of competitive advantage--they have already earned credibility and respect from others, who regularly look to them for guidance. When sharing their views, they significantly influence the acceptance or rejection of new initiatives. Influence leaders reach into every conversation, every meeting, and every decision made in an organization. The important question is whether they will exert their leadership in support or in opposition to changes you propose. By identifying influence leaders and inviting them to join a group to discuss change initiatives, physician executives can create a positive force for change.

  5. A minimal ingroup advantage in emotion identification confidence.

    Young, Steven G; Wilson, John Paul

    2016-12-28

    Emotion expressions convey valuable information about others' internal states and likely behaviours. Accurately identifying expressions is critical for social interactions, but so is perceiver confidence when decoding expressions. Even if a perceiver correctly labels an expression, uncertainty may impair appropriate behavioural responses and create uncomfortable interactions. Past research has found that perceivers report greater confidence when identifying emotions displayed by cultural ingroup members, an effect attributed to greater perceptual skill and familiarity with own-culture than other-culture faces. However, the current research presents novel evidence for an ingroup advantage in emotion decoding confidence across arbitrary group boundaries that hold culture constant. In two experiments using different stimulus sets participants not only labeled minimal ingroup expressions more accurately, but did so with greater confidence. These results offer novel evidence that ingroup advantages in emotion decoding confidence stem partly from social-cognitive processes.

  7. Polyploidy in haloarchaea: advantages for growth and survival

    PubMed Central

    Zerulla, Karolin; Soppa, Jörg

    2014-01-01

    The investigated haloarchaeal species, Halobacterium salinarum, Haloferax mediterranei, and H. volcanii, have all been shown to be polyploid. They contain several replicons that have independent copy number regulation, and most have a higher copy number during exponential growth phase than in stationary phase. The possible evolutionary advantages of polyploidy for haloarchaea, most of which have experimental support for at least one species, are discussed. These advantages include a low mutation rate and high resistance toward X-ray irradiation and desiccation, which depend on homologous recombination. For H. volcanii, it has been shown that gene conversion operates in the absence of selection, which leads to the equalization of genome copies. On the other hand, selective forces might lead to heterozygous cells, which have been verified in the laboratory. Additional advantages of polyploidy are survival over geological times in halite deposits as well as at extreme conditions on earth and at simulated Mars conditions. Recently, it was found that H. volcanii uses genomic DNA as genetic material and as a storage polymer for phosphate. In the absence of phosphate, H. volcanii dramatically decreases its genome copy number, thereby enabling cell multiplication, but diminishing the genetic advantages of polyploidy. Stable storage of phosphate is proposed as an alternative driving force for the emergence of DNA in early evolution. Several additional potential advantages of polyploidy are discussed that have not been addressed experimentally for haloarchaea. An outlook summarizes selected current trends and possible future developments. PMID:24982654

  8. Biotechnology offers revolution to fish health management.

    PubMed

    Adams, Alexandra; Thompson, Kim D

    2006-05-01

    Biotechnology has many applications in fish health management. The application of monoclonal antibodies (mAbs) provides a rapid means of pathogen identification; antibodies to immunoglobulins from different fish species can be used to monitor the host response following vaccination; and mAbs also have the potential for screening broodstock for previous exposure to pathogens. Luminex technology exemplifies a novel antibody-based method that can be applied to both pathogen detection and vaccine development. Molecular technologies, such as the polymerase chain reaction (PCR), real time PCR and nucleic acid sequence-based amplification (NASBA), have enabled detection, identification and quantification of extremely low levels of aquatic pathogens, and microarray technologies offer a new dimension to multiplex screening for pathogens and host response. Recombinant DNA technology permits large-scale, low-cost vaccine production, moreover DNA vaccination, proteomics, adjuvant design and oral vaccine delivery will undoubtedly foster the development of effective fish vaccines in the future.

  9. Organic proxies in speleothems - New developments, advantages and limitations

    NASA Astrophysics Data System (ADS)

    Blyth, Alison J.; Hartland, Adam; Baker, Andy

    2016-10-01

    Research into organic matter in speleothems has progressed recently to encompass new analytical approaches and applications, which offer increased potential in areas such as palaeo-temperature reconstruction and high-resolution palaeo-environmental records from the Quaternary. Here we review three major areas of relevance for future work in the field - the origin, transport and transformation of the organic matter which is ultimately preserved in speleothems; the types of proxies currently available for use or in development, and their advantages and issues; and the recently developed prospect of high-resolution organic matter records derived from the analysis of organic/trace elements complexes. The continuing extension of work in these research areas offers excellent potential for organic speleothem proxies to grow as a valuable tool in palaeoenvironmental research.

    Phenylethynyl containing reactive additives were prepared from aromatic diamine, containing phenylethvnvl groups and various ratios of phthalic anhydride and 4-phenylethynviphthalic anhydride in glacial acetic acid to form the imide in one step or in N-methyl-2-pvrrolidinone to form the amide acid intermediate. The reactive additives were mixed in various amounts (10% to 90%) with oligomers containing either terminal or pendent phenylethynyl groups (or both) to reduce the melt viscosity and thereby enhance processability. Upon thermal cure, the additives react and become chemically incorporated into the matrix and effect an increase in crosslink density relative to that of the host resin. This resultant increase in crosslink density has advantageous consequences on the cured resin properties such as higher glass transition temperature and higher modulus as compared to that of the host resin.

  12. Cycad mutualist offers more than pollen transport.

    PubMed

    Marler, Thomas E

    2010-05-01

    Specialist insects share obligate mutualisms with some contemporary cycad species whereby the insect's pollination services are rewarded with a nursery in which the insect's larvae consume the postdispersal male cone. I prevented visits of the pollinator moth Anatrachyntis sp. to male Cycas micronesica (Cycadaceae) cones to show that consumption of the cone tissue by the mutualist hastened initiation of the plant's subsequent reproductive event. This is the first documented case where removal of a postdispersal cycad pollination organ speeds up subsequent reproductive events, and the current paradigm that the offering of cone tissue as a nursery is a sacrifice by the plant in return for the pollination services is therefore inaccurate. In C. micronesica, the herbivory stage of pollination mutualism confers a cryptic benefit of cone tissue disposal, which translates into an increase in ultimate lifetime reproductive effort. The plant population relies on the pollinator for moving gametes, as well as for increasing the number of male coning events. The dual benefits afforded to the plant by associating with this pollinator shows that mutualism can operate simultaneously on very different traits.

  13. THE HOME ADVANTAGE IN MAJOR LEAGUE BASEBALL.

    PubMed

    Jones, Marshall B

    2015-12-01

    Home advantage is smaller in baseball than in other major professional sports for men, specifically football, basketball, or soccer. This paper advances an explanation. It begins by reviewing the main observations to support the view that there is little or no home advantage in individual sports. It then presents the case that home advantage originates in impaired teamwork among the away players. The need for teamwork and the extent of it vary from sport to sport. To the extent that a sport requires little teamwork it is more like an individual sport, and the home team would be expected to enjoy only a small advantage. Interactions among players on the same side (teamwork) are much less common in baseball than in the other sports considered.

    We present here evidence for the existence of a citation advantage within astrophysics for papers that link to data. Using simple measures based on publication data from NASA Astrophysics Data System we find a citation advantage for papers with links to data receiving on the average significantly more citations per paper than papers without links to data. Furthermore, using INSPEC and Web of Science databases we investigate whether either papers of an experimental or theoretical nature display different citation behavior.

  15. Do neural networks offer something for you?

    SciTech Connect

    Ramchandran, S.; Rhinehart, R.R.

    1995-11-01

    The concept of neural network computation was inspired by the hope to artifically reproduce some of the flexibility and power of the human brain. Human beings can recognize different patterns and voices even though these signals do not have a simple phenomenological understanding. Scientists have developed artificial neural networks (ANNs) for modeling processes that do not have a simple phenomenological explanation, such as voice recognition. Consequently, ANN jargon can be confusing to process and control engineers. In simple terms, ANNs take a nonlinear regression modeling approach. Like any regression curve-fitting approach, a least-squares optimization can generate model parameters. One advantage of ANNs is that they require neither a priori understanding of the process behavior nor phenomenological understanding of the process. ANNs use data describing the input/output relationship in a process to {open_quotes}learn{close_quotes} about the underlying process behavior. As a result of this, ANNs have a wide range of applicability. Furthermore, ANNs are computationally efficient and can replace models that are computationally intensive. This can make real-time online model-based applications practicable. A neural network is a dense mesh of nodes and connections. The basic processing elements of a network are called neurons. Neural networks are organized in layers, and typically consist of at least three layers: an input layer, one or more hidden layers, and an output layer. The input and output layers serve as interfaces that perform appropriate scaling between `real-world` and network data. Hidden layers are so termed because their neurons are hidden to the real-world data. Connections are the means for information flow. Each connection has an associated adjustable weight, w{sub i}. The weight can be regarded as a measure of the importance of the signals between the two neurons. 7 figs.

    The Oilheat Advantages Project is the Oilheat Manufacturers Association`s first project. It involves the creation and disseminaiton of the unified, well documented, compellingly packaged oilheat story. The project invovles three steps: the first step is to pull together all the existing data on the advantages of oilheat into a single, well documented engineering report. The second step will be to rewrite and package the technical document into a consumer piece and a scripted presentation supported with overheads, and to disseminate the information throughout the industry. The third step will be to fund new research to update existing information and discover new advantages of oilheat. This step will begin next year. The inforamtion will be packaged in the following formats: The Engineering Document. This will include all the technical information including the creditable third party sources for all the findings on the many advantages of oilheat; the Consumer Booklet. This summarizes all the findings in the Engineering Document in simple language with easy to understand illustrations and graphs; a series of single topic Statement Stuffers on each of the advantages; an Overhead Transparency-Supported Scripted Show that can be used by industry representatives for presentations to the general public, schools, civic groups, and service clubs; and the Periodic publication of updates to the Oilheat Advantages Study.

    2014-05-01

    Additive manufacturing (AM) refers to an advanced technology used for the fabrication of three-dimensional near-net-shaped functional components directly from computer models, using unit materials. The fundamentals and working principle of AM offer several advantages, including near-net-shape capabilities, superior design and geometrical flexibility, innovative multi-material fabrication, reduced tooling and fixturing, shorter cycle time for design and manufacturing, instant local production at a global scale, and material, energy, and cost efficiency. Well suiting the requests of modern manufacturing climate, AM is viewed as the new industrial revolution, making its way into a continuously increasing number of industries, such as aerospace, defense, automotive, medical, architecture, art, jewelry, and food. This overview was created to relate the historical evolution of the AM technology to its state-of-the-art developments and emerging applications. Generic thoughts on the microstructural characteristics, properties, and performance of AM-fabricated materials will also be discussed, primarily related to metallic materials. This write-up will introduce the general reader to specifics of the AM field vis-à-vis advantages and common techniques, materials and properties, current applications, and future opportunities.

  20. Fast, automatically darkening welding filter offering an improved level of safety

    NASA Astrophysics Data System (ADS)

    Palmer, Stephen

    1996-03-01

    A mode of operation is introduced for the standard 90 degrees twisted nematic (TN) liquid-crystal cell when placed together with an interference filter and positioned between crossed polarizers such that a small stimulating voltage of between 2.0 and 3.0 V is required in order to attain the light state. Further incrementation of the driving electronics reverts the system back to a darker phase. Such cells offer advantages over those of the standard 90 degrees TN device operating in the normally white mode, in that the unit maintains the fast response time from the light to the dark state associated with the employment of TN cells placed between crossed polarizers. In addition, a low transmittance state is achieved when the unit is in the inactivated phase; this is an effect usually correlated with the normally black mode of operation. These cells are therefore ideal candidates for incorporation into fast, automatically darkening, welding filters that are designed to change rapidly from the light to the dark protective state, while offering an improved level of safety by not holding in a potentially hazardous light state should the controlling electronics malfunction. The requirement for this phenomenon to be observed is that the cell displays a low optical transmittance over the green wavelengths of the visible spectrum when in the inactivated phase and placed between crossed polarizers. The presence of an interference filter that possesses a peak transmittance over the central part of the visible spectrum is also necessary. It is shown that there are only two possible cell types that satisfy this criteria, and the optical properties of such cells are analyzed in some detail.

  2. Is There an Islamist Political Advantage?

    Cammett, Melani; Luong, Pauline Jones

    2014-01-01

    There is a widespread presumption that Islamists have an advantage over their opponents when it comes to generating mass appeal and winning elections. The question remains, however, as to whether these advantages—or, what we refer to collectively as an Islamist political advantage—actually exist. We argue that—to the extent that Islamists have a political advantage—the primary source of this advantage is reputation rather than the provision of social services, organizational capacity, or ideological hegemony. Our purpose is not to dismiss the main sources of the Islamist governance advantage identified in scholarly literature and media accounts, but to suggest a different causal path whereby each of these factors individually and sometimes jointly promotes a reputation for Islamists as competent, trustworthy, and pure. It is this reputation for good governance that enables Islamists to distinguish themselves in the streets and at the ballot box. PMID:25767370

    Rice is an important crop and major model plant for monocot functional genomics studies. With the establishment of various genetic resources for rice genomics, the next challenge is to systematically assign functions to predicted genes in the rice genome. Compared with the robustness of genome sequencing and bioinformatics techniques, progress in understanding the function of rice genes has lagged, hampering the utilization of rice genes for cereal crop improvement. The use of transfer DNA (T-DNA) insertional mutagenesis offers the advantage of uniform distribution throughout the rice genome, but preferentially in gene-rich regions, resulting in direct gene knockout or activation of genes within 20-30 kb up- and downstream of the T-DNA insertion site and high gene tagging efficiency. Here, we summarize the recent progress in functional genomics using the T-DNA-tagged rice mutant population. We also discuss important features of T-DNA activation- and knockout-tagging and promoter-trapping of the rice genome in relation to mutant and candidate gene characterizations and how to more efficiently utilize rice mutant populations and datasets for high-throughput functional genomics and phenomics studies by forward and reverse genetics approaches. These studies may facilitate the translation of rice functional genomics research to improvements of rice and other cereal crops.

  8. High-Temperature Coatings Offer Energy Savings

    NASA Technical Reports Server (NTRS)

    2012-01-01

    The U.S. X-Plane Program included the first-of-its-kind research in aerodynamics and astronautics with experimental vehicles, including the first aircraft to break the sound barrier; the first aircraft to fly in excess of 100,000, then 200,000, and then 300,000 feet; and the first aircraft to fly at three, four, five, and then six times the speed of sound. During the 1990s, NASA started developing a new thermal protection material to test on the X-33 and X-34 supersonic aircraft. The X-33 was intended to demonstrate the technologies needed for a new reusable launch vehicle and was projected to reach an altitude of approximately 50 miles and speeds of more than Mach 11. The X-34, a small, reusable technology demonstrator for a launch vehicle, was intended to reach an altitude of 250,000 feet and fly at speeds of Mach 8. As a result of its research and development efforts, NASA s Ames Research Center invented the Protective Ceramic Coating Material (PCCM). Applied to a surface, the thin, lightweight coating could protect the material underneath from extreme temperatures. The capability of the technology came from its emissivity, which radiated heat away from the surface it covered, thereby decreasing the amount of heat transferred to the underlying material. PCCM not only increased the capability of materials to withstand higher temperatures, it also exhibited impressive thermal shock, vibration, and acoustic performance. In addition, it proved to be resistant to abrasion and mechanical damage and was also environmentally safe, due to it being water-based and containing no solvents. Even though funding for the X-33 and X-34 ended in 2001, PCCM continued on a path of innovation.

  5. Sterilization project offers model for better care.

    PubMed

    Finger, W R

    1993-08-01

    India's experiences with sterilization indicate that quality of care is an essential feature of appropriate, voluntary family planning services. Good quality of care reduces the problems associated with services and increases client's acceptability and continuation rates. The Center for Excellence in India has established a model that emphasis matching the right method with each client's circumstances. The model first developed standards, which were based on international guidelines and expertise, and then developed and implemented a training program for providers; finally, a quality assurance system was established in order to promote compliance with standards. At present, there is not 100% agreement among international guidelines on standards for sterilization or other methods. In 1992, Family Health International (FHI) published a comparison on 8 major sets of service, delivery, guidelines, and were used around the world; FHI world wide variations in guidelines. A USAID study group is currently reviewing scientific evidence on oral contraceptives, injectables, Norplant, and IUDS. There is difficulty in reaching international consensus and even greater difficulty in changing approaches and policies of specific countries. It is much easier to institute quality of care issues at the beginning of program development or when methods are first introduced. In India, the Centers of Excellence program developed its own national standards on sterilization, and the resulting document is specifically suited to India. The standards emphasize the client's choice and human issues such as counseling and communication. Sterilization reversal, which is not always successful, will be provided, even though sterilization will be promoted as a permanent procedure. 4 regional centers have been set up through medical colleges in Delhi, Calcutta, Bombay and Madras. 12 additional state level centers will be established in the future.

  10. VLA Study Offers Clue to Galaxy Formation

    NASA Astrophysics Data System (ADS)

    2004-11-01

    Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope to study the most distant known quasar have found a tantalizing clue that may answer a longstanding cosmic chicken-and-egg question: which came first, supermassive black holes or giant galaxies? VLA Image of Quasar VLA Image of Quasar J1148+5251 CREDIT: Walter et al., NRAO/AUI/NSF (Click on Image for Larger Version) For years, astronomers have noted a direct relationship between the mass of a galaxy's central, supermassive black hole and the total mass of the "bulge" of stars at its core. The more massive the black hole, the more massive the bulge. Scientists have speculated extensively about whether the black hole or the stellar bulge formed first. Recently, some theories have suggested that the two may form simultaneously. However, the new VLA observations of a quasar and its host galaxy seen as they were when the Universe was less than a billion years old indicate that the young galaxy has a supermassive black hole but no massive bulge of stars. "We found a large amount of gas in this young galaxy, and, when we add the mass of this gas to that of the black hole, they add up to nearly the total mass of the entire system. The dynamics of the galaxy imply that there isn't much mass left to make up the size of stellar bulge predicted by current models," said Chris Carilli, of the National Radio Astronomy Observatory (NRAO), in Socorro, NM. The scientists studied a quasar dubbed J1148+5251, that, at more than 12.8 billion light-years, is the most distant quasar yet found. Discovered in 2003 by the Sloan Digital Sky Survey, J1148+5251 is a young galaxy with a bright quasar core seen as it was when the Universe was only 870 million years old. The Universe now is 13.7 billion years old. Aiming the VLA at J1148+4241 for about 60 hours, the researchers were able to determine the amount of molecular gas in the system. In addition, they were able to measure the motions of that gas

  11. Despite cost and risk, ORYX PLUS offers benchmarking bonanza.

    PubMed

    1998-02-01

    The Joint Commission's ORYX-PLUS option offers standardized measurement, risk adjustment, and reporting of outcomes not available in the less comprehensive ORYX program. This should create a wealth of truly comparable data against which to benchmark. There are additional costs: $2,500 to the Joint Commission, plus more expensive software and maintenance. This means the program is probably best suited for those systems that already have significant investments in information systems. As ORYX-PLUS eventually will issue performance report cards to the public on participants, there are the risks associated with disclosure. On the other hand, participating hospitals will be able to boast participation in a voluntary disclosure program aimed at excellence.

  12. Sustainable competitive advantage for accountable care organizations.

    PubMed

    Macfarlane, Michael Alex

    2014-01-01

    In the current period of health industry reform, accountable care organizations (ACOs) have emerged as a new model for the delivery of high-quality and cost-effective healthcare. However, few ACOs operate in direct competition with one another, and the accountable care business model has yet to present a means of continually developing new marginal value for patients and network partners. With value-based purchasing and patient consumerism strengthening as market forces, ACOs must build organizational sustainability and competitive advantage to meet the value demands set by customers and competitors. This essay proposes a strategy, adapted from the disciplines of agile software development and Lean product development, through which ACOs can engage internal and external customers in the development of new products that will provide sustainability and competitive advantage to the organization by decreasing waste in development, promoting specialized knowledge, and closely targeting customer value.

  13. Were there evolutionary advantages to premenstrual syndrome?

    PubMed Central

    Gillings, Michael R

    2014-01-01

    Premenstrual syndrome (PMS) affects up to 80% of women, often leading to significant personal, social and economic costs. When apparently maladaptive states are widespread, they sometimes confer a hidden advantage, or did so in our evolutionary past. We suggest that PMS had a selective advantage because it increased the chance that infertile pair bonds would dissolve, thus improving the reproductive outcomes of women in such partnerships. We confirm predictions arising from the hypothesis: PMS has high heritability; gene variants associated with PMS can be identified; animosity exhibited during PMS is preferentially directed at current partners; and behaviours exhibited during PMS may increase the chance of finding a new partner. Under this view, the prevalence of PMS might result from genes and behaviours that are adaptive in some societies, but are potentially less appropriate in modern cultures. Understanding this evolutionary mismatch might help depathologize PMS, and suggests solutions, including the choice to use cycle-stopping contraception. PMID:25469168

  14. Will the Latino Mortality Advantage Endure?

    PubMed Central

    Goldman, Noreen

    2016-01-01

    Persons of Mexican origin and some other Latino groups in the US have experienced a survival advantage compared with their non-Latino white counterparts, a pattern known as the Latino, Hispanic or epidemiological paradox. However, high rates of obesity and diabetes among Latinos relative to whites and continued increases in the prevalence of these conditions suggest that this advantage may soon disappear. Other phenomena, including high rates of disability in the older Latino population compared with whites, new evidence of health declines shortly after migration to the US, increasing environmental stressors for immigrants, and high risk values of inflammatory markers among Latinos compared with whites support this prediction. One powerful counterargument, however, is substantially lower smoking-attributable mortality among Latinos. Still, it is questionable as to whether smoking behavior can counteract the many forces at play that may impede Latinos from experiencing future improvements in longevity on a par with whites.

  15. Improving the design of competitive bidding in Medicare Advantage.

    PubMed

    Cawley, John H; Whitford, Andrew B

    2007-04-01

    In 2003, Congress passed the Medicare Prescription Drug, Improvement, and Modernization Act, which required that in 2006 the Centers for Medicare and Medicaid Services (CMS) implement a system of competitive bids to set payments for the Medicare Advantage program. Managed care plans now bid for the right to enroll Medicare beneficiaries. Data from the first year of bidding suggest that imperfect competition is limiting the success of the bidding system. This article offers suggestions to improve this system based on findings from auction theory and previous government-run auctions. In particular, CMS can benefit by adjusting its system of competitive bids in four ways: credibly committing to regulations governing bidding; limiting the scope for collusion, entry deterrence, and predatory behavior among bidders; adjusting how benchmark reimbursement rates are set; and accounting for asymmetric information among bidders.

  16. Solar thermal upper stage: Economic advantage and development status

    Adams, Alan M.

    1995-01-01

    A solar thermal upper stage (STUS) is envisioned as a propulsive concept for the future. The STUS will be used for low Earth orbit (LEO) to geostationary-Earth orbit (GEO) transfer and for planetary exploration missions. The STUS offers significant performance gains over conventional chemical propulsion systems. These performance gains translate into a more economical, more efficient method of placing useful payloads in space and maximizing the benefits derived from space activity. This paper will discuss the economical advantages of an STUS compared to conventional chemical propulsion systems, the potential market for an STUS, and the recent activity in the development of an STUS. The results of this assessment combined with the performance gains, will provide a strong justification for the development of an STUS.

    Theanine, γ-glutamylethylamide, is one of the major amino acid components in green tea. On the basis of the preventive effect of theanine intake after weaning on stress-induced impairment of recognition memory, the advantageous effect of theanine intake on recognition memory was examined in young rats, which were fed water containing 0.3% theanine for 3 weeks after weaning. The rats were subjected to object recognition test. Object recognition memory was maintained in theanine-administered rats 48 hours after the training, but not in the control rats. When in vivo dentate gyrus long-term potentiation (LTP) was induced, it was more greatly induced in theanine-administered rats than in the control rats. The levels of brain-derived neurotropic factor and nerve growth factor in the hippocampus were significantly higher in theanine-administered rats than in the control rats. The present study indicates the advantageous effect of theanine intake after weaning on recognition memory. It is likely that theanine intake is of advantage to the development of hippocampal function after weaning.

  19. Explaining Asian Americans' academic advantage over whites.

    PubMed

    Hsin, Amy; Xie, Yu

    2014-06-10

    The superior academic achievement of Asian Americans is a well-documented phenomenon that lacks a widely accepted explanation. Asian Americans' advantage in this respect has been attributed to three groups of factors: (i) socio-demographic characteristics, (ii) cognitive ability, and (iii) academic effort as measured by characteristics such as attentiveness and work ethic. We combine data from two nationally representative cohort longitudinal surveys to compare Asian-American and white students in their educational trajectories from kindergarten through high school. We find that the Asian-American educational advantage is attributable mainly to Asian students exerting greater academic effort and not to advantages in tested cognitive abilities or socio-demographics. We test explanations for the Asian-white gap in academic effort and find that the gap can be further attributed to (i) cultural differences in beliefs regarding the connection between effort and achievement and (ii) immigration status. Finally, we highlight the potential psychological and social costs associated with Asian-American achievement success.

  6. Enforced Clonality Confers a Fitness Advantage

    PubMed Central

    Martínková, Jana; Klimešová, Jitka

    2016-01-01

    In largely clonal plants, splitting of a maternal plant into potentially independent plants (ramets) is usually spontaneous; however, such fragmentation also occurs in otherwise non-clonal species due to application of external force. This process might play an important yet largely overlooked role for otherwise non-clonal plants by providing a mechanism to regenerate after disturbance. Here, in a 5-year garden experiment on two short-lived, otherwise non-clonal species, Barbarea vulgaris and Barbarea stricta, we compared the fitness of plants fragmented by simulated disturbance (“enforced ramets”) both with plants that contemporaneously originate in seed and with individuals unscathed by the disturbance event. Because the ability to regrow from fragments is related to plant age and stored reserves, we compared the effects of disturbance applied during three different ontogenetic stages of the plants. In B. vulgaris, enforced ramet fitness was higher than the measured fitness values of both uninjured plants and plants established from seed after the disturbance. This advantage decreased with increasing plant age at the time of fragmentation. In B. stricta, enforced ramet fitness was lower than or similar to fitness of uninjured plants and plants grown from seed. Our results likely reflect the habitat preferences of the study species, as B. vulgaris occurs in anthropogenic, disturbed habitats where body fragmentation is more probable and enforced clonality thus more advantageous than in the more natural habitats preferred by B. stricta. Generalizing from our results, we see that increased fitness yielded by enforced clonality would confer an evolutionary advantage in the face of disturbance, especially in habitats where a seed bank has not been formed, e.g., during invasion or colonization. Our results thus imply that enforced clonality should be taken into account when studying population dynamics and life strategies of otherwise non-clonal species in disturbed

    The successful dentist of the future will establish a sustainable competitive advantage in the marketplace by recognising that patients undergoing dental treatment cannot see the result before purchase, and that they therefore look for signs of service quality to reduce uncertainty. Thus the successful dentist will implement a quality programme that recognises not only that quality is defined by meeting patients' needs and expectations, but also that quality service is fundamental to successful business strategy. Finally, the successful dentist of the future will realise that the pursuit of quality is a never-ending process which requires leadership by example.

    each organ, together with external and cut-surface features. A third section allows the examiner to report other observations not requested previously, while a final section is also provided for the epicrisis and for the formulation of the final diagnosis, the same as that reported in the first form. The database is coupled with an interactive system for collecting voice comments, thereby replacing the need for tape-recorders in the autopsy room. The user can recall a dictation window, dictate a text, check spelling and insert additional text. The database is also coupled to an image acquisition system, on the assumption that moving images allow a more faithful documentation of reality. Therefore, all rooms in which autopsies are carried out on fetuses or neonates have been equipped with a fixed camera linked to a monitor and a video-recorder. A PCB, used for image digitalization, recognizes up to 16,000,000 different colors. Guided by dedicated software, image files are transferred to a computer and then saved with the autoptic report. The database can be consulted and queried in two principle ways: by key words in the contents or main disease descriptions, or by individual words or phrases contained within the complete text of the reports. The present database system for autopsy reporting has proved itself useful in a pathological anatomy service. The combined presence of images and texts renders the system useful also as a research tool. By linking to a Web site dedicated to pathologic anatomy, it will be possible to display online rare cases involving diagnostic difficulties. The system offers great advantages for present and retrospective diagnostics, as well as for research and education purposes.

  17. Rural Medicare Advantage Plan Payment in 2015.

    PubMed

    Kemper, Leah; Barker, Abigail R; McBride, Timothy D; Mueller, Keith

    2015-12-01

    Payment to Medicare Advantage (MA) plans was fundamentally altered in the Patient Protection and Affordable Care Act of 2010 (ACA). MA plans now operate under a new formula for county-level payment area benchmarks, and in 2012 began receiving quality-based bonus payments. The Medicare Advantage Quality Bonus Payment Demonstration expanded the bonus payments to most MA plans through 2014; however, with the end of the demonstration bonus payments has been reduced for intermediate quality MA plans. This brief examines the impact that these changes in MA baseline payment are having on MA plans and beneficiaries in rural and urban areas. Key Data Findings. (1) Payments to plans in rural areas were 3.9 percent smaller under ACA payment policies in 2015 than they would have been in the absence of the ACA. For plans in urban areas, the payments were 8.8 percent smaller than they would have been. These figures were determined using hypothetical pre-ACA and actual ACA-mandated benchmarks for 2015. (2) MA plans in rural areas received an average annual bonus payment of $326.77 per enrollee in 2014, but only $63.76 per enrollee in 2015, with the conclusion of the demonstration. (3) In 2014, 92 percent of rural MA beneficiaries were in a plan that received quality-based bonus payments under the demonstration, while in March 2015, 56 percent of rural MA beneficiaries were in a plan that was eligible for quality-based bonus payments.

  18. An evolutionary advantage for extravagant honesty.

    PubMed

    Bullock, Seth

    2012-01-07

    A game-theoretic model of handicap signalling over a pair of signalling channels is introduced in order to determine when one channel has an evolutionary advantage over the other. The stability conditions for honest handicap signalling are presented for a single channel and are shown to conform with the results of prior handicap signalling models. Evolutionary simulations are then used to show that, for a two-channel system in which honest signalling is possible on both channels, the channel featuring larger advertisements at equilibrium is favoured by evolution. This result helps to address a significant tension in the handicap principle literature. While the original theory was motivated by the prevalence of extravagant natural signalling, contemporary models have demonstrated that it is the cost associated with deception that stabilises honesty, and that the honest signals exhibited at equilibrium need not be extravagant at all. The current model suggests that while extravagant and wasteful signals are not required to ensure a signalling system's evolutionary stability, extravagant signalling systems may enjoy an advantage in terms of evolutionary attainability.

    The development of additive manufacturing methods has enlarged rapidly in recent years. Thereby, the work mainly focuses on the realization of mechanical components, but the additive manufacturing technology offers a high potential in the field of optics as well. Owing to new design possibilities, completely new solutions are possible. This article briefly reviews and compares the most important additive manufacturing methods for polymer optics. Additionally, it points out the characteristics of additive manufactured polymer optics. Thereby, surface quality is of crucial importance. In order to improve it, appropriate post-processing steps are necessary (e.g. robot polishing or coating), which will be discussed. An essential part of this paper deals with various additive manufactured optical components and their use, especially in optical systems for shape metrology (e.g. borehole sensor, tilt sensor, freeform surface sensor, fisheye lens). The examples should demonstrate the potentials and limitations of optical components produced by additive manufacturing.

  20. Evolutionary advantage of small populations on complex fitness landscapes.

    PubMed

    Jain, Kavita; Krug, Joachim; Park, Su-Chan

    2011-07-01

    Recent experimental and theoretical studies have shown that small asexual populations evolving on complex fitness landscapes may achieve a higher fitness than large ones due to the increased heterogeneity of adaptive trajectories. Here, we introduce a class of haploid three-locus fitness landscapes that allow the investigation of this scenario in a precise and quantitative way. Our main result derived analytically shows how the probability of choosing the path of the largest initial fitness increase grows with the population size. This makes large populations more likely to get trapped at local fitness peaks and implies an advantage of small populations at intermediate time scales. The range of population sizes where this effect is operative coincides with the onset of clonal interference. Additional studies using ensembles of random fitness landscapes show that the results achieved for a particular choice of three-locus landscape parameters are robust and also persist as the number of loci increases. Our study indicates that an advantage for small populations is likely whenever the fitness landscape contains local maxima. The advantage appears at intermediate time scales, which are long enough for trapping at local fitness maxima to have occurred but too short for peak escape by the creation of multiple mutants.

  1. Advantages and Challenges of Superconducting Accelerators

    NASA Astrophysics Data System (ADS)

    Krischel, Detlef

    After a short review of the history toward high-energy superconducting (SC) accelerators for ion beam therapy (IBT), an overview is given on material properties and technical developments enabling to use SC components in a medical accelerator for full body cancer treatment. The design concept and the assembly of a commercially available SC cyclotron for proton therapy (PT) are described and the potential advantages for applying superconductivity are assessed. The discussion includes the first years of operation experience with regard to cryogenic and magnetic performance, automated beam control, and maintenance aspects. An outlook is given on alternative machine concepts for protons-only or for heavier ions. Finally, it is discussed whether the application of superconductivity might be expanded in the future to a broader range of subsystems of clinical IBT accelerators such as SC magnets for transfer beam lines or gantries.

  2. Optical advantages in retinal scanning displays

    2000-06-01

    Virtual Retinal DisplayTM technology is a retinal scanning display (RSD) technology being developed at Microvision, Inc., for a variety of applications including microdisplays. An RSD scans a modulated light beam onto a viewer's retina to produce a perceived image. Red, green and blue light sources, such as lasers, laser diodes or LEDs combine with Microvision's proprietary miniaturized scanner designs to make the RSD very well suited for head-worn and helmet-mounted displays (HMD). This paper compares the features of RSD technology to other display technologies such as the cathode ray tubes or matrix-based displays for HMD and other wearable display applications, and notes important performance advantages due to the number of pixel- generating elements. Also discussed are some fundamental optical limitations for virtual displays used in the HMD applications.

  3. The mechanical defence advantage of small seeds.

    PubMed

    Fricke, Evan C; Wright, S Joseph

    2016-08-01

    Seed size and toughness affect seed predators, and size-dependent investment in mechanical defence could affect relationships between seed size and predation. We tested how seed toughness and mechanical defence traits (tissue density and protective tissue content) are related to seed size among tropical forest species. Absolute toughness increased with seed size. However, smaller seeds had higher specific toughness both within and among species, with the smallest seeds requiring over 2000 times more energy per gram to break than the largest seeds. Investment in mechanical defence traits varied widely but independently of the toughness-mass allometry. Instead, a physical scaling relationship confers a toughness advantage on small seeds independent of selection on defence traits and without a direct cost. This scaling relationship may contribute to seed size diversity by decreasing fitness differences among large and small seeds. Allometric scaling of toughness reconciles predictions and conflicting empirical relationships between seed size and predation.

  4. Accounting for the Down syndrome advantage?

    The authors examined factors that could explain the higher levels of psychosocial well being observed in past research in mothers of individuals with Down syndrome compared with mothers of individuals with other types of intellectual disabilities. The authors studied 155 mothers of adults with Down syndrome, contrasting factors that might validly account for the ?Down syndrome advantage? (behavioral phenotype) with those that have been portrayed in past research as artifactual (maternal age, social supports). The behavioral phenotype predicted less pessimism, more life satisfaction, and a better quality of the mother?child relationship. However, younger maternal age and fewer social supports, as well as the behavioral phenotype, predicted higher levels of caregiving burden. Implications for future research on families of individuals with Down syndrome are discussed.

    Understanding the fundamental patterns and determinants of human cooperation and the maintenance of social order in human societies is a challenge across disciplines. The existing empirical evidence for the higher levels of cooperation when altruistic punishment is present versus when it is absent systematically ignores the institutional competition inherent in human societies. Whether punishment would be deliberately adopted and would similarly enhance cooperation when directly competing with nonpunishment institutions is highly controversial in light of recent findings on the detrimental effects of punishment. We show experimentally that a sanctioning institution is the undisputed winner in a competition with a sanction-free institution. Despite initial aversion, the entire population migrates successively to the sanctioning institution and strongly cooperates, whereas the sanction-free society becomes fully depopulated. The findings demonstrate the competitive advantage of sanctioning institutions and exemplify the emergence and manifestation of social order driven by institutional selection.

    Acceleration of a common car with with a turbocharged diesel engine is compared to the same type with an electric motor in terms of kinematics. Starting from a state of rest, the electric car reaches a distant spot earlier than the diesel car, even though the latter has a better specification for engine power and average acceleration from 0 to 100 km h-1. A three phase model of acceleration as a function of time fits the data of the electric car accurately. The first phase is a quadratic growth of acceleration in time. It is shown that the tenfold higher coefficient for the first phase accounts for most of the kinematic advantage of the electric car.

  7. Longitudinal research strategies: advantages, problems, and prospects.

    PubMed

    Farrington, D P

    1991-05-01

    The single-cohort, long-term longitudinal survey has many advantages in comparison with a cross-sectional survey in advancing knowledge about offending and other types of psychopathology, notably in providing information about onset and desistance, about continuity and prediction, and about within-individual change. However, the longitudinal survey also has significant problems, notably in confounding aging and period effects, delayed results, achieving continuity in funding and research direction, and cumulative attrition. This paper suggests the use of a multiple-cohort sequential strategy (the "accelerated longitudinal design") as a way of achieving the benefits of the longitudinal method while minimizing the problems in advancing knowledge about the natural history, causes, prevention, and treatment of psychopathological disorders.

    Medulloblastomas are the most common malignant childhood brain tumors arising in the posterior fossa. Treatment improvements for these tumors have meant that there are a greater number of survivors, but this long-term patient survival has increased the awareness of resulting neurocognitive deficits. Impairments in attention, memory, executive functions, and intelligence quotient demonstrate that the cerebellum likely plays a significant role in numerous higher cognitive functions such as language, cognitive, and emotional functions. In addition, children with medulloblastoma not only have cerebellar lesions but also brain white matter damages due to radiation and chemotherapy. Functional neuroimaging, a noninvasive method with many advantages, has become the standard tool in clinical and cognitive neuroscience research. By reviewing functional neuroimaging studies, this review aims to clarify the role of the cerebellum in cognitive function and explain more clearly cognitive sequelae due to polytherapy in children with medulloblastoma. This review suggests that the posterior cerebellar lobes are crucial to maintaining cognitive performance. Clinical investigations could help to better assess the involvement of these lobes in cognitive functions.

  10. Offering Global Collaboration Services beyond CERN and HEP

    NASA Astrophysics Data System (ADS)

    Fernandes, J.; Ferreira, P.; Baron, T.

    2015-12-01

    The CERN IT department has built over the years a performant and integrated ecosystem of collaboration tools, from videoconference and webcast services to event management software. These services have been designed and evolved in very close collaboration with the various communities surrounding the laboratory and have been massively adopted by CERN users. To cope with this very heavy usage, global infrastructures have been deployed which take full advantage of CERN's international and global nature. If these services and tools are instrumental in enabling the worldwide collaboration which generates major HEP breakthroughs, they would certainly also benefit other sectors of science in which globalization has already taken place. Some of these services are driven by commercial software (Vidyo or Wowza for example), some others have been developed internally and have already been made available to the world as Open Source Software in line with CERN's spirit and mission. Indico for example is now installed in 100+ institutes worldwide. But providing the software is often not enough and institutes, collaborations and project teams do not always possess the expertise, or human or material resources that are needed to set up and maintain such services. Regional and national institutions have to answer needs, which are growingly global and often contradict their operational capabilities or organizational mandate and so are looking at existing worldwide service offers such as CERN's. We believe that the accumulated experience obtained through the operation of a large scale worldwide collaboration service combined with CERN's global network and its recently- deployed Agile Infrastructure would allow the Organization to set up and operate collaborative services, such as Indico and Vidyo, at a much larger scale and on behalf of worldwide research and education institutions and thus answer these pressing demands while optimizing resources at a global level. Such services would

    2017-04-01

    Mesenchymal stem cell (MSC) research progressively moves towards clinical phases. Accordingly, a wide range of different procedures were presented in the literature for MSC isolation from human tissues; however, there is not yet any close focus on the details to offer precise information for best method selection. Choosing a proper isolation method is a critical step in obtaining cells with optimal quality and yield in companion with clinical and economical considerations. In this concern, current review widely discusses advantages of omitting proteolysis step in isolation process and presence of tissue pieces in primary culture of MSCs, including removal of lytic stress on cells, reduction of in vivo to in vitro transition stress for migrated/isolated cells, reduction of price, processing time and labour, removal of viral contamination risk, and addition of supporting functions of extracellular matrix and released growth factors from tissue explant. In next sections, it provides an overall report of technical highlights and molecular events of explant culture method for isolation of MSCs from human tissues including adipose tissue, bone marrow, dental pulp, hair follicle, cornea, umbilical cord and placenta. Focusing on informative collection of molecular and methodological data about explant methods can make it easy for researchers to choose an optimal method for their experiments/clinical studies and also stimulate them to investigate and optimize more efficient procedures according to clinical and economical benefits.

    ATTRACT is a project that intends to provide telemedicine services over Cable Television Networks. ATTRACT is an European Commission funded project (Healthcare Telematics). The main objective of ATTRACT is to take advantage of emerging European Cable Television network infrastructures and offer cost-effective care to patients at home. This will be achieved through a set of broadband network applications that competitively provide low cost interactive health-care services at home. The applications will be based on existing or developing European Cable Television network infrastructures in order to provide all kind of users with affordable homecare services. It is ATTRACT's intention that citizens and users benefit from high quality access to home telemedical services which also implies cost savings for patients, their families and the already over burdened health institutions. In addition, the European industries will have extensive opportunities to develop, evaluate and validate broadband network infrastructures providing multimedia and interactive telemedical services at home. ATTRACT contributes to the EU telecommunications and telematics policy objectives that promote the development and validation of "applications and services" which "provide an intelligent telematic environment for the patient in institutions and other points of care that helps the patient to continue, as far as possible, normal activities and external communication".

  13. Precise Positioning with Multi-GNSS and its Advantage for Seismic Parameters Inversion

    NASA Astrophysics Data System (ADS)

    2015-12-01

    Together with the ongoing modernization of U.S. GPS and Russian GLONASS, the two new emerging global navigation satellite systems (BeiDou from China and Galileo from European Union) have already been running and multi-GNSS era is coming. Compared with single system, multi-GNSS can significantly improve the satellite visibility, optimize the spatial geometry, reduce dilution of precision and will be of great benefits to both scientific applications and engineering services. In this contribution, we focus mainly on its potential advantages for earthquake parameters estimation and tsunami early warning. First, we assess the precise positioning performance of multi-GNSS by an out-door experiment on a shaking table. Three positioning methods were used to retrieve the simulated seismic signal: precise point positioning (PPP), variometric approach for displacements analysis stand-alone engine (VADASE) and temporal point positioning (TPP). In addition to that, with respect to VADASE and TPP, we extended the original dual-frequency model to single-frequency model and then tested the algorithms. Accuracy, reliability, and continuity were evaluated and analyzed in detail accordingly. Our results revealed that multi-GNSS offer more precise and robust positioning results over GPS-only. At last, as a case study, multi-GNSS data recorded during 2014 Pisagua Earthquake were re-processed. Using co-seismic displacements from GPS and multi-GNSS, earthquake and the aftermath tsunami were inverted, respectively.

  14. Using integration technology as a strategic advantage.

    Fry, P A

    1993-08-01

    The underlying premise of the Managed Competition Act previously cited is that through managed competition providers will be forced to lower care costs while increasing the level of positive care outcomes. Because it may also be that tomorrow's hospitals will find a severe rationing of technology, what can they do to prepare? Most of the systems in place today already have built within them all the necessary potential to address this premise and technology requirement with no change, no conversion, no expense for new equipment and software, and no disruption in day-to-day operations, just a little re-engineering. Today, however, these systems are similar to a 20-mule team pulling in different directions: all the power is there, but the wagon remains motionless and totally unable to reach its objective. It takes a skilled wagonmaster to bring them together, to make the mules work as a cohesive unit, to make the power of 20 mules greater than the sum of 20 mules. So it is and will be for the hospital of tomorrow. System integration is no longer a question of whether but of when. Those hospitals that use it today as a strategic advantage will be in a better position tomorrow to use it as a competitive strategic advantage in an environment that will reward low cost and high positive care outcomes and will penalize those that cannot compete. The technology is already here and economically within reach of nearly every hospital, just waiting to be used. The question that must nag all of us who want to make the health care system of America better is, Why not make the when now? Rich Helppie, president of Superior Consultant Company, summarized the solution well: The old ways will not give way to the new overnight. The re-engineering process in healthcare must evolve. Compared to the last 20 years, however, such evolution may appear to be a massive, forthright, complete, comprehensive, drastic and rapid revolution. Survival is the name of the game, and for healthcare

    Introduction Remote video consultations between clinician and patient are technically possible and increasingly acceptable. They are being introduced in some settings alongside (and occasionally replacing) face-to-face or telephone consultations. Methods To explore the advantages and limitations of video consultations, we will conduct in-depth qualitative studies of real consultations (microlevel) embedded in an organisational case study (mesolevel), taking account of national context (macrolevel). The study is based in 2 contrasting clinical settings (diabetes and cancer) in a National Health Service (NHS) acute trust in London, UK. Main data sources are: microlevel—audio, video and screen capture to produce rich multimodal data on 45 remote consultations; mesolevel—interviews, ethnographic observations and analysis of documents within the trust; macrolevel—key informant interviews of national-level stakeholders and document analysis. Data will be analysed and synthesised using a sociotechnical framework developed from structuration theory. Ethics approval City Road and Hampstead NHS Research Ethics Committee, 9 December 2014, reference 14/LO/1883. Planned outputs We plan outputs for 5 main audiences: (1) academics: research publications and conference presentations; (2) service providers: standard operating procedures, provisional operational guidance and key safety issues; (3) professional bodies and defence societies: summary of relevant findings to inform guidance to members; (4) policymakers: summary of key findings; (5) patients and carers: ‘what to expect in your virtual consultation’. Discussion The research literature on video consultations is sparse. Such consultations offer potential advantages to patients (who are spared the cost and inconvenience of travel) and the healthcare system (eg, they may be more cost-effective), but fears have been expressed that they may be clinically risky and/or less acceptable to patients or staff, and they

  16. Prochlorococcus: advantages and limits of minimalism.

    Partensky, Frédéric; Garczarek, Laurence

    2010-01-01

    Prochlorococcus is the key phytoplanktonic organism of tropical gyres, large ocean regions that are depleted of the essential macronutrients needed for photosynthesis and cell growth. This cyanobacterium has adapted itself to oligotrophy by minimizing the resources necessary for life through a drastic reduction of cell and genome sizes. This rarely observed strategy in free-living organisms has conferred on Prochlorococcus a considerable advantage over other phototrophs, including its closest relative Synechococcus, for life in this vast yet little variable ecosystem. However, this strategy seems to reach its limits in the upper layer of the S Pacific gyre, the most oligotrophic region of the world ocean. By losing some important genes and/or functions during evolution, Prochlorococcus has seemingly become dependent on co-occurring microorganisms. In this review, we present some of the recent advances in the ecology, biology, and evolution of Prochlorococcus, which because of its ecological importance and tiny genome is rapidly imposing itself as a model organism in environmental microbiology.

  17. Competitive advantages of Caedibacter-infected Paramecia.

    Intracellular bacteria of the genus Caedibacter limit the reproduction of their host, the freshwater ciliate Paramecium. Reproduction rates of infected strains of paramecia were significantly lower than those of genetically identical strains that had lost their parasites after treatment with an antibiotic. Interference competition occurs when infected paramecia release a toxic form of the parasitic bacterium that kills uninfected paramecia. In mixed cultures of infected and uninfected strains of either P tetraurelia or of P novaurelia, the infected strains outcompeted the uninfected strains. Infection of new host paramecia seems to be rare. Infection of new hosts was not observed in either mixtures of infected with uninfected strains, or after incubation of paramecia with isolated parasites. The competitive advantages of the host paramecia, in combination with their vegetative reproduction, makes infection of new hosts by the bacterial parasites unnecessary, and could be responsible for the continued existence of "killer paramecia" in nature. Caedibacter parasites are not a defensive adaptation. Feeding rates and reproduction of the predators Didinium nasutum (Ciliophora) and Amoeba proteus (Amoebozoa, Gymnamoebia) were not influenced by whether or not their paramecia prey were infected. Infection of the predators frequently occurred when they preyed on infected paramecia. Caedibacter-infected predators may influence competition between Paramecium strains by release of toxic parasites into the environment that are harmful to uninfected strains.

    High critical temperature superconductors have zero power consumption and could be used to produce ideal electric power lines. The principal obstacle in fabricating superconducting wires and tapes is grain boundaries—the misalignment of crystalline orientations at grain boundaries, which is unavoidable for polycrystals, largely deteriorates critical current density. Here we report that high critical temperature iron pnictide superconductors have advantages over cuprates with respect to these grain boundary issues. The transport properties through well-defined bicrystal grain boundary junctions with various misorientation angles (θGB) were systematically investigated for cobalt-doped BaFe2As2 (BaFe2As2:Co) epitaxial films fabricated on bicrystal substrates. The critical current density through bicrystal grain boundary (JcBGB) remained high (>1 MA cm−2) and nearly constant up to a critical angle θc of ∼9°, which is substantially larger than the θc of ∼5° for YBa2Cu3O7–δ. Even at θGB>θc, the decay of JcBGB was much slower than that of YBa2Cu3O7–δ. PMID:21811238

    Carbon-ion radiotherapy (C-ion RT) possesses physical and biological advantages. It was started at NIRS in 1994 using the Heavy Ion Medical Accelerator in Chiba (HIMAC); since then more than 50 protocol studies have been conducted on almost 4000 patients with a variety of tumors. Clinical experiences have demonstrated that C-ion RT is effective in such regions as the head and neck, skull base, lung, liver, prostate, bone and soft tissues, and pelvic recurrence of rectal cancer, as well as for histological types including adenocarcinoma, adenoid cystic carcinoma, malignant melanoma and various types of sarcomas, against which photon therapy could be less effective. Furthermore, when compared with photon and proton RT, a significant reduction of overall treatment time and fractions has been accomplished without enhancing toxicities. Currently, the number of irradiation sessions per patient averages 13 fractions spread over approximately three weeks. This means that in a carbon therapy facility a larger number of patients than is possible with other modalities can be treated over the same period of time.

  1. Inferring causal structure: a quantum advantage

    Ried, Katja; Spekkens, Robert

    2014-03-01

    The problem of inferring causal relations from observed correlations is central to science, and extensive study has yielded both important conceptual insights and widely used practical applications. Yet some of the simplest questions are impossible to answer classically: for instance, if one observes correlations between two variables (such as taking a new medical treatment and the subject's recovery), does this show a direct causal influence, or is it due to some hidden common cause? We develop a framework for quantum causal inference, and show how quantum theory provides a unique advantage in this decision problem. The key insight is that certain quantum correlations can only arise from specific causal structures, whereas pairs of classical variables can exhibit any pattern of correlation regardless of whether they have a common cause or a direct-cause relation. For example, suppose one measures the same Pauli observable on two qubits. If they share a common cause, such as being prepared in an entangled state, then one never finds perfect (positive) correlations in every basis, whereas perfect anticorrelations are possible (if one prepares the singlet state). Conversely, if a channel connects the qubits, hence a direct causal influence, perfect anticorrelations are impossible.

    OBJECTIVE--To determine whether the increased prevalence of childhood eczema in advantaged socioeconomic groups is due to increased parental reporting. DESIGN--Comparison of parental reports of eczema with visible eczema recorded by medical officers during a detailed physical examination. SETTING--National birth cohort study. SUBJECTS--8279 children from England, Wales, and Scotland born during 3-9 March 1958 and followed up at the ages of 7, 11, and 16. MAIN OUTCOME MEASURES--Prevalence of eczema according to parental report compared with medical officer's examination at the ages of 7, 11, and 16. RESULTS--Prevalence of both reported and examined eczema increased with rising social class at the ages of 7, 11, and 16 years. The point prevalence of examined eczema at age 7 was 4.8%, 3.6%, 3.6%, 2.4%, 2.2%, and 2.4% in social classes I, II, III non-manual, III manual, IV, and V respectively (chi 2 value for linear trend 12.6, P < 0.001). This trend persisted after adjustment for potential confounders such as region and family size and was not present for examined psoriasis or acne. CONCLUSIONS--Eczema is more prevalent among British schoolchildren in social classes I and II than those in lower classes. Exposures associated with social class are probably at least as important as genetic factors in the expression of childhood eczema. PMID:8173454

  3. The advantages and disadvantages of pacifier use.

    A powerful reflex of the infant in the weeks following birth is sucking. Breastfed babies benefit from both the nutrition in mother's milk and the satisfaction of their sucking instinct. Babies that can not be breastfed due to various reasons may satisfy their sucking instinct by using pacifiers. Pacifier use and digit sucking are believed to be harmless habits. In many places of the world, and especially in developing countries, pacifier use in early childhood is very common. It is said that pacifier use eases the baby and satisfies its sucking instinct. It has been reported in several studies that pacifier use reduces the risk of Sudden Infant Death Syndrome (SIDS). The most important risks of this non-nutritive sucking habit are failure of breastfeeding, dental deformities, recurrent acute otitis media, and the possibility of accidents. The development of latex allergy, tooth decay, oral ulcers and sleep disorders are other problems encountered with pacifier use. Parents may hesitate to use pacifiers for their babies and consult nurses or midwives on this issue. In this article, the advantages and disadvantages of pacifier use are discussed with the aim of providing guidance to nurses and midwives working in the field of pediatrics and infant health.

  4. Advantages of a leveled commitment contracting protocol

    Sandholm, T.W.; Lesser, V.R.

    1996-12-31

    In automated negotiation systems consisting of self-interested agents, contracts have traditionally been binding. Such contracts do not allow agents to efficiently accommodate future events. Game theory has proposed contingency contracts to solve this problem. Among computational agents, contingency contracts are often impractical due to large numbers of interdependent and unanticipated future events to be conditioned on, and because some events are not mutually observable. This paper proposes a leveled commitment contracting protocol that allows self-interested agents to efficiently accommodate future events by having the possibility of unilaterally decommitting from a contract based on local reasoning. A decommitment penalty is assigned to both agents in a contract: to be freed from the contract, an agent only pays this penalty to the other party. It is shown through formal analysis of several contracting settings that this leveled commitment feature in a contracting protocol increases Pareto efficiency of deals and can make contracts individually rational when no full commitment contract can. This advantage holds even if the agents decommit manipulatively.

  5. Advantages of expanded universal carrier screening: what is at stake?

    Expanded universal carrier screening (EUCS) entails a twofold expansion of long-standing (preconception) carrier screening programmes: it not only allows the simultaneous screening of a large list of diseases ('expanded'), but also refers to a pan-ethnic screening offer ('universal'). Advocates mention three main moral advantages of EUCS as compared with traditional (targeted and/or ancestry-based) forms of carrier screening: EUCS will (1) maximise opportunities for autonomous reproductive choice by informing prospective parents about a much wider array of reproductive risks; (2) provide equity of access to carrier testing services; (3) reduce the risk of stigmatisation. This empirical ethics study aims to widen this account and provide a balanced picture of the potential pros and cons of EUCS. Semi-structured interviews were conducted with 17 health (policy) professionals and representatives of patient organisations about their views on carrier screening including a possible EUCS scenario. Stakeholders acknowledged the potential benefits of EUCS, but also expressed five main moral concerns: (1) Does EUCS respond to an urgent problem or population need? (2) Is it possible to offer couples both understandable and sufficient information about EUCS? (3) How will societal views on 'reproductive responsibility' change as a result of EUCS? (4) Will EUCS lead to a lower level of care for high-risk populations? (5) Will EUCS reinforce disability-based stigmatisation? While having the potential to overcome some moral limits inherent in traditional carrier screening, EUCS comes with moral challenges of its own. More research is needed to (further) anticipate the ethical and practical consequences of EUCS.

  10. [The precautionary principle: advantages and risks].

    PubMed

    Tubiana, M

    2001-04-01

    The extension of the precautionary principle to the field of healthcare is the social response to two demands of the population: improved health safety and the inclusion of an informed public in the decision-making process. The necessary balance between cost (treatment-induced risk) and benefit (therapeutic effect) underlies all healthcare decisions. An underestimation or an overestimation of cost, i.e. risk, is equally harmful in public healthcare. A vaccination should be prescribed when its beneficial effect outweighs its inevitable risk. Mandatory vaccination, such as in the case of the Hepatitis B virus, is a health policy requiring some courage because those who benefit will never be aware of its positive effect while those who are victims of the risk could resort to litigation. Defense against such accusations requires an accurate assessment of risk and benefit, which underlines the importance of expertise. Even within the framework of the precautionary principle, it is impossible to act without knowledge, or at least a plausible estimation, of expected effects. Recent affairs (blood contamination, transmissible spongiform encephalitis by growth hormone, and new variant of Creutzfeldt-Jacob disease) illustrate that in such cases the precautionary principle would have had limited impact and it is only when enough knowledge was available that effective action could be taken. Likewise, in current debates concerning the possible risks of electromagnetic fields, cellular phones and radon, research efforts must be given priority. The general public understands intuitively the concept of cost and benefit. For example, the possible health risks of oral contraceptives and hormone replacement therapy were not ignored, but the public has judged that their advantages justify the risk. Estimating risk and benefit and finding a balance between risk and preventive measures could help avoid the main drawbacks of the precautionary principle, i.e. inaction and refusal of

  17. Searching for the Advantages of Virus Sex

    NASA Astrophysics Data System (ADS)

    Turner, Paul E.

    2003-02-01

    Sex (genetic exchange) is a nearly universal phenomenon in biological populations. But this is surprising given the costs associated with sex. For example, sex tends to break apart co-adapted genes, and sex causes a female to inefficiently contribute only half the genes to her offspring. Why then did sex evolve? One famous model poses that sex evolved to combat Muller's ratchet, the mutational load that accrues when harmful mutations drift to high frequencies in populations of small size. In contrast, the Fisher-Muller Hypothesis predicts that sex evolved to promote genetic variation that speeds adaptation in novel environments. Sexual mechanisms occur in viruses, which feature high rates of deleterious mutation and frequent exposure to novel or changing environments. Thus, confirmation of one or both hypotheses would shed light on the selective advantages of virus sex. Experimental evolution has been used to test these classic models in the RNA bacteriophage φ6, a virus that experiences sex via reassortment of its chromosomal segments. Empirical data suggest that sex might have originated in φ6 to assist in purging deleterious mutations from the genome. However, results do not support the idea that sex evolved because it provides beneficial variation in novel environments. Rather, experiments show that too much sex can be bad for φ6 promiscuity allows selfish viruses to evolve and spread their inferior genes to subsequent generations. Here I discuss various explanations for the evolution of segmentation in RNA viruses, and the added cost of sex when large numbers of viruses co-infect the same cell.

  18. 2014: Rural Medicare Advantage Enrollment Update.

    PubMed

    Kemper, Leah; Barker, Abigail; McBride, Timothy; Mueller, Keith

    2015-01-01

    Key Data Findings. (1) Reclassification of rural and urban county designations (due to the switch from 2000 census data to 2010 census data) resulted in a 10 percent decline in the number of Medicare eligible Americans living in rural counties in 2014 (from roughly 10.7 million to 9.6 million). These changes also resulted in a decline in the number of MA enrollees considered to be living in a rural area, from 2.19 million to 1.95 million. However, the percentage of Medicare beneficiaries enrolled in MA and prepaid plans in rural areas declined only slightly from 20.6 percent to 20.3 percent. (2) Rural Medicare Advantage (MA) and other prepaid plan enrollment in March 2014 was nearly 1.95 million, or 20.3 percent of all rural Medicare beneficiaries, an increase of more than 216,000 from March 2013. Enrollment increased to 1.99 million (20.4 percent) in October 2014. (3) In March 2014, 56 percent of rural MA enrollees were enrolled in Preferred Provider Organization (PPO) plans, 29 percent were enrolled in Health Maintenance Organization (HMO) or Point-of-Service (POS) plans, 7 percent were enrolled in Private Fee-for-Service (PFFS) plans, and 8 percent were enrolled in other prepaid plans, including Cost plans and Program of All-Inclusive Care for the Elderly (PACE) plans. (4) States with the highest percentage of rural Medicare beneficiaries enrolled in MA and other prepaid plans include Minnesota (49.1 percent), Hawaii (41.1 percent), Pennsylvania (35.4 percent), Wisconsin (34.3 percent), New York (30.4 percent), and Ohio (30.1 percent).

Results of this study help pave the knowledge foundation for management of the behavioural healthcare to learn how to apply state-of-the-art information technology to offer higher quality, clinically proven effective services at lower costs than those of their competitors.

  20. Advantages and limitations of clear-native PAGE.

    PubMed

    Wittig, Ilka; Schägger, Hermann

    2005-11-01

    Clear-native PAGE (CN-PAGE) separates acidic water-soluble and membrane proteins (pI < 7) in an acrylamide gradient gel, and usually has lower resolution than blue-native PAGE (BN-PAGE). The migration distance depends on the protein intrinsic charge, and on the pore size of the gradient gel. This complicates estimation of native masses and oligomerization states when compared to BN-PAGE, which uses negatively charged protein-bound Coomassie-dye to impose a charge shift on the proteins. Therefore, BN-PAGE rather than CN-PAGE is commonly used for standard analyses. However, CN-PAGE offers advantages whenever Coomassie-dye interferes with techniques required to further analyze the native complexes, e.g., determination of catalytic activities, as shown here for mitochondrial ATP synthase, or efficient microscale separation of membrane protein complexes for fluorescence resonance energy transfer (FRET) analyses. CN-PAGE is milder than BN-PAGE. Especially the combination of digitonin and CN-PAGE can retain labile supramolecular assemblies of membrane protein complexes that are dissociated under the conditions of BN-PAGE. Enzymatically active oligomeric states of mitochondrial ATP synthase previously not detected using BN-PAGE were identified by CN-PAGE.

    2008-07-01

    The possibility of rehabilitating immediately an edentulous patient offers today remarkable advantages because it satisfies the patient's demands for comfort, aesthetics, and functionality and reduces the surgical stages for the professional.In the last years clinicians and companies have been concentrating their efforts in the development of new surgical techniques and biomaterials in order to speed up the osteointegration process, which fosters the functionality, that is the immediate-loading.This clinical report, based on the analysis of the literature and on the presentation of a case report, shows how satisfying results in functionality and aesthetic can be obtained by a careful diagnosis and an accurate therapeutic planning, reducing at the same time the stress for the patient and the surgical stages for the professional.In any case, it is necessary to have the rehabilitations with immediate-loaded implants directed by workers with a good knowledge and experience in surgery, periodontology, and prosthesis or by a work team able to face all the complications such advanced rehabilitations may cause.

  2. Does the end-to-end venous anastomosis offer a functional advantage over the end-to-side venous anastomosis in high-output arteriovenous grafts?

    PubMed

    1990-12-01

    This study explores the hemodynamics, mechanics, and biologic response of end-to-end versus end-to-side venous anastomoses in a canine arteriovenous graft model. Femoral polytetrafluoroethylene grafts were implanted bilaterally in a paired fashion (n = 22). Detailed local hemodynamic measurements were made by use of color Doppler ultrasound imaging at 1, 4, 8, and 12 weeks after implant. Measurements included volumetric flow rate and Doppler-derived spectral window (percent window) as a measure of turbulence. Amplitude and velocity of vessel wall movement were also measured. Volume of perivascular tissue vibration quantitated kinetic energy transfer through the vessel wall. Volumetric flow rate (end to end, 1013 +/- 70 ml/min; end to side, 1015 +/- 72 ml/min), percent window (end to end, 6.6% +/- 0.6%, end to side, 5.6% +/- 0.4%) and volume of perivascular tissue vibration (end to end, 19.6 +/- 1.2 ml, end to side, 16.3 +/- 1.8 ml) were statistically equivalent in the two graft types (end to end vs end to side p greater than 0.05). Both graft types developed venous intimal-medial thickening of a similar magnitude: end to end, 0.35 +/- 0.05 mm, end to side, 0.43 +/- 0.09 mm, normal vein 0.070 +/- 0.004 mm (analysis of variance [ANOVA] p less than 0.001, p less than 0.01 for end to end or end to side vs control, end to end vs end to side p greater than 0.05 by Student-Newman-Keuls test). The best correlations with venous intimal-medial thickening were obtained from inverse percent window (r = 0.84, p less than 0.001) and volume of perivascular tissue vibration (r = 0.68, p less than 0.001). In the end to end configuration the relative amplitude of venous wall movement decreased, and the relative velocity of wall motion increased over time. We conclude that in the circumstances of this high flow arteriovenous graft model the end-to-end venous anastomosis does not significantly differ from the end-to-side venous anastomosis in terms of flow stability, turbulence, or kinetic energy transfer. The magnitude of the hyperplastic response is statistically equivalent for the two anastomotic types, but the pattern is somewhat different, possibly providing evidence for differences in stress distribution. Differences in the relative amplitude and velocity of vessel wall movement suggest that anastomotic geometry may affect the way in which kinetic energy is dissipated at the graft/vessel interface.

    We propose that self-affirmation may endow people more psychological resources to buffer against the negative influence of rejecting unfair offers in the classic ultimatum game (UG) and further lead to a stronger tendency to reject those offers. We tested this possibility by conducting an event-related potential (ERP) study about the UG, with the ERP component P3 as an indirect indicator of psychological resources. Participants were randomly assigned to the affirmation or control condition and then completed the UG through electrophysiological recording. As expected, the behavioral data indicated that compared with unaffirmed ones, affirmed participants were more likely to reject unfair UG offers; the electrophysiological data indicated that compared to the unaffirmed, affirmed participants showed a greater P3 in response to the presentation of an offer. These findings suggest that psychological resources may play a role in rejecting others beyond the fairness concern, and additionally shed light on the neural mechanisms underlying self-affirmation.

    2013-01-01

    Background Many audiologists have observed a situation where a patient appears to understand something spoken by his/her spouse or a close friend but not the same information spoken by a stranger. However, it is not clear whether this observation reflects choice of communication strategy or a true benefit derived from the talker’s voice. Purpose The current study measured the benefits of long-term talker familiarity for older individuals with hearing impairment in a variety of listening situations. Research Design In Experiment 1, we measured speech recognition with familiar and unfamiliar voices when the difficulty level was manipulated by varying levels of a speech-shaped background noise. In Experiment 2, we measured the benefit of a familiar voice when the background noise was other speech (informational masking). Study Sample A group of 31 older listeners with high-frequency sensorineural hearing loss participated in the study. Fifteen of the participants served as talkers, and sixteen as listeners. In each case, the talker-listener pair for the familiar condition represented a close, long-term relationship (spouse or close friend). Data Collection and Analysis Speech-recognition scores were compared using controlled stimuli (low-context sentences) recorded by the study talkers. The sentences were presented in quiet and in two levels of speech-spectrum noise (Experiment 1) as well as in multitalker babble (Experiment 2). Repeated-measures analysis of variance was used to compare performance between the familiar and unfamiliar talkers, within and across conditions. Results Listeners performed better when speech was produced by a talker familiar to them, whether that talker was in a quiet or noisy environment. The advantage of the familiar talker was greater in a more adverse listening situation (i.e., in the highest level of background noise), but was similar for speech-spectrum noise and multi-talker babble. Conclusions The present data support a frequent

  7. Berkeley Program Offers New Option for Financing Residential PV Systems

    SciTech Connect

    Bolinger, Mark A

    2008-07-06

    Readily accessible credit has often been cited as a necessary ingredient to open up the market for residential photovoltaic (PV) systems. Though financing does not reduce the high up-front cost of PV, by spreading that cost over some portion of the system's life, financing can certainly make PV systems more affordable. As a result, a number of states have, in the past, set up special residential loan programs targeting the installation of renewable energy systems and/or energy-efficiency improvements and often featuring low interest rates, longer terms and no-hassle application requirements. Historically, these loan programs have had mixed success (particularly for PV), for a variety of reasons, including a historical lack of homeowner interest in PV, a lack of program awareness, a reduced appeal in a low-interest-rate environment, and a tendency for early PV adopters to be wealthy and not in need of financing. Some of these barriers have begun to fade. Most notably, homeowner interest in PV has grown in some states, particularly those that offer solar rebates. The passage of the Energy Policy Act of 2005 (EPAct 2005), however, introduced one additional roadblock to the success of low-interest PV loan programs: a residential solar investment tax credit (ITC), subject to the Federal government's 'anti-double-dipping' rules. Specifically, the residential solar ITC--equal to 30% of the system's tax basis, capped at $2000--will be reduced or offset if the system also benefits from what is known as 'subsidized energy financing', which is likely to include most government-sponsored low-interest loan programs. Within this context, it has been interesting to note the recent flurry of announcements from a number of U.S cities concerning a new type of PV financing program. Led by the city of Berkeley, Calif., these cities propose to offer their residents the ability to finance the installation of a PV system using increased property tax assessments, rather than a more

  8. Laboratory in a box: wearable sensors and its advantages for gait analysis.

    PubMed

    Najafi, Bijan; Khan, Tahir; Wrobel, James

    2011-01-01

    Until recently, many gait studies explored potential gait alteration due to various disorders in the gait lab and using camera based systems and force platforms. However, these strategies may not replicate normal outdoor walking. Using this equipment, it is more difficult to measure the variability of walking which is important for maintaining balance and responding to different walking challenges. Additionally, subjects may mask their problem or exaggerate it when they are walking in a short walking distance offered by laboratory based-technology. This study overviews some of the key advantages of wearable technology compared to laboratory-based instrument. Additionally, it explored gait patterns over ample distance of walking compared to walking distance restricted to a gait laboratory environment. Walking patterns of ten healthy young subjects were examined using a wearable sensor technology in a random order over a distance of 7 m, 14 m, and 20 m. Results suggest that participants walk significantly faster by increasing walking distance on average by 15% and 3% when walking distance was increased respectively from 7 m to 14 and from 14 m to 20 m (p<0.05). Interestingly despite a high test-retest reliability for averaged gait parameters (ICC>0.89), the test-retest reliability for gait variability was only acceptable during 20 m walking distance (ICC<0.3 for 7 m and 14 m v. ICC=0.65 for 20 m). Taken together, our findings indicate that for valid and reliable assessment of gait parameters, gait should be performed over ample walking distances. Body worn sensor technology facilitates assessing gait outside of a gait laboratory, over ample walking distance, different footwear condition, different walking surface, and in environment where mimics better true environment where the subject is active in.

  9. Assessment of potential advantages of relevant ions for particle therapy: A model based study

    Purpose: Different ion types offer different physical and biological advantages for therapeutic applications. The purpose of this work is to assess the advantages of the most commonly used ions in particle therapy, i.e., carbon ({sup 12}C), helium ({sup 4}He), and protons ({sup 1}H) for different treatment scenarios. Methods: A treatment planning analysis based on idealized target geometries was performed using the treatment planning software TRiP98. For the prediction of the relative biological effectiveness (RBE) that is required for biological optimization in treatment planning the local effect model (LEM IV) was used. To compare the three ion types, the peak-to-entrance ratio (PER) was determined for the physical dose (PER{sub PHY} {sub S}), the RBE (PER{sub RBE}), and the RBE-weighted dose (PER{sub BIO}) resulting for different dose-levels, field configurations, and tissue types. Further, the dose contribution to artificial organs at risk (OAR) was assessed and a comparison of the dose distribution for the different ion types was performed for a patient with chordoma of the skull base. Results: The study showed that the advantages of the ions depend on the physical and biological properties and the interplay of both. In the case of protons, the consideration of a variable RBE instead of the clinically applied generic RBE of 1.1 indicates an advantage in terms of an increased PER{sub RBE} for the analyzed configurations. Due to the fact that protons show a somewhat better PER{sub PHY} {sub S} compared to helium and carbon ions whereas helium shows a higher PER{sub RBE} compared to protons, both protons and helium ions show a similar RBE-weighted dose distribution. Carbon ions show the largest variation of the PER{sub RBE} with tissue type and a benefit for radioresistant tumor types due to their higher LET. Furthermore, in the case of a two-field irradiation, an additional gain in terms of PER{sub BIO} is observed when using an orthogonal field configuration

    Researchers involved in Earth observation and atmospheric monitoring have been offered a tantalizing opportunity. The satellite-communications company Iridium, which is due to launch a flotilla of 66 satellites within the next decade, has offered to put remote-sensing instruments into each one, thus creating an Earth-observing constellation that would cost many billions of dollars to build from scratch. Such a huge project would have the ability to study fastchanging phenomena by viewing the same spot on Earth every few minutes. "It does offer something that is not available by any other means," says atmospheric chemist Paul Monks of Leicester University in the UK.

    Microbial contamination is an obstacle to widespread production of advanced biofuels and chemicals. Current practices such as process sterilization or antibiotic dosage carry excess costs or encourage the development of antibiotic resistance. We engineered Escherichia coli to assimilate melamine, a xenobiotic compound containing nitrogen. After adaptive laboratory evolution to improve pathway efficiency, the engineered strain rapidly outcompeted a control strain when melamine was supplied as the nitrogen source. We additionally engineered the yeasts Saccharomyces cerevisiae and Yarrowia lipolytica to assimilate nitrogen from cyanamide and phosphorus from potassium phosphite, and they outcompeted contaminating strains in several low-cost feedstocks. Supplying essential growth nutrients through xenobiotic or ecologically rare chemicals provides microbial competitive advantage with minimal external risks, given that engineered biocatalysts only have improved fitness within the customized fermentation environment.

  1. Advantages and Disadvantages of Mammography Screening

    PubMed Central

    2011-01-01

    Summary Mammography screening is the only method presently considered appropriate for mass screening of asymptomatic women. Its frequent use, however, warrants diligent analysis of potential side effects. Radiation risk is far below the natural yearly risk of breast cancer and should not be used as an argument against screening. False-positive calls lead to additional imaging or histopathological assessment, mainly percutaneous breast biopsy. These measures are tolerated and accepted fairly well. Their number is limited by strict quality assurance and constant training. Interval cancers represent a limitation of breast screening that should prompt further research for optimization. Evaluation of overdiagnosis is a highly debated topic in the literature. According to the probably most realistic available calculations, overdiagnosis is acceptable as it is compensated by the potential mortality reduction. Nonetheless, this potential side effect warrants optimal adjustment of therapy to the patient's individual risk. The mortality reduction seen in randomized studies was confirmed by results from national screening programs. A recent case referent study indicated that improvements in mortality reduction run parallel to improved mammographic techniques. Use of less aggressive therapies is another valuable effect of screening. Awareness of potential problems, strict quality assurance, and further research should help to further develop screening programs. PMID:21779225

    There is a rising interest in developing functional electronics using additively manufactured components. Considerations in materials selection and pathways to forming hybrid circuits and devices must demonstrate useful electronic function; must enable integration; and must complement the complex shape, low cost, high volume, and high functionality of structural but generally electronically passive additively manufactured components. This article reviews several emerging technologies being used in industry and research/development to provide integration advantages of fabricating multilayer hybrid circuits or devices. First, we review a maskless, noncontact, direct write (DW) technology that excels in the deposition of metallic colloid inks for electrical interconnects. Second, we review a complementary technology, aerosol deposition (AD), which excels in the deposition of metallic and ceramic powder as consolidated, thick conformal coatings and is additionally patternable through masking. As a result, we show examples of hybrid circuits/devices integrated beyond 2-D planes, using combinations of DW or AD processes and conventional, established processes.

    2012-10-01

    This study examined whether the home advantage varies for open-air, domed, or retractable-roof baseball stadia, and whether having the roof open or closed affects the home advantage in retractable-roof baseball stadia. Data from Major League Baseball (MLB) games played between 2001 and 2009 were analyzed for whether or not the presence of a home-advantage was dependent on the type of home stadium used. Home advantage was robust for all three types of stadia. A significant effect of stadium type on home advantage was found, with a greater home advantage for teams playing home games in domed stadia relative to open-air stadia, replicating a previous study. There was a greater home advantage for teams playing home games in domed stadia relative to retractable-roof stadia. No other differences in the home advantage were found; results are discussed in terms of familiarity with the facility.

  4. Clinical advantages of dual activity in urticaria.

    PubMed

    Kontou-Fili, K

    2000-01-01

    Urticaria is a common disorder that adversely affects quality of life; work-related and recreational activities are restricted, while rest, sleep, and emotions are seriously disturbed in a significant proportion of patients. The pathogenic mechanisms vary, but cutaneous mast-cell activation with release of histamine and other vasoactive or proinflammatory mediators is thought to be the final common pathway for lesion induction in most cases. A subsequent, but incompletely understood, late-phase allergic reaction seems to prolong the inflammatory process, particularly in certain chronic forms of the disorder. Although histamine is considered an important mediator of urticaria, additional substances, including the cysteinyl leukotrienes (LTs), are putative mediators of the immediate urticarial responses and the inflammatory events that follow in some types of urticaria. A second-generation antihistamine, mizolastine, which exhibits dual activity with selective H1-receptor antagonism and, as shown in animal studies, anti-5-lipoxygenase activity, represents an advance in the treatment of urticaria. It has rapid, potent and sustained action. At the recommended 10-mg dose, mizolastine suppresses the histamine-induced wheal reaction as early as 1 h after oral administration. Compared to placebo, mizolastine significantly reduces overall patient discomfort and pruritus in patients with chronic idiopathic urticaria. Double-blind, placebo-controlled studies have also shown mizolastine to be at least as effective as other second-generation antihistamines. Furthermore, with long-term use of mizolastine over 1 year, a reduction in pruritus and the number of urticarial episodes was maintained with no evidence of tachyphylaxis or tolerance. Mizolastine has also been shown to be an effective treatment for cold-induced urticaria, causing significant delay in the whealing response to the ice-cube test and also reducing the wheal diameter.

  7. Zebrafish models of human motor neuron diseases: advantages and limitations.

    PubMed

    Babin, Patrick J; Goizet, Cyril; Raldúa, Demetrio

    2014-07-01

    Motor neuron diseases (MNDs) are an etiologically heterogeneous group of disorders of neurodegenerative origin, which result in degeneration of lower (LMNs) and/or upper motor neurons (UMNs). Neurodegenerative MNDs include pure hereditary spastic paraplegia (HSP), which involves specific degeneration of UMNs, leading to progressive spasticity of the lower limbs. In contrast, spinal muscular atrophy (SMA) involves the specific degeneration of LMNs, with symmetrical muscle weakness and atrophy. Amyotrophic lateral sclerosis (ALS), the most common adult-onset MND, is characterized by the degeneration of both UMNs and LMNs, leading to progressive muscle weakness, atrophy, and spasticity. A review of the comparative neuroanatomy of the human and zebrafish motor systems showed that, while the zebrafish was a homologous model for LMN disorders, such as SMA, it was only partially relevant in the case of UMN disorders, due to the absence of corticospinal and rubrospinal tracts in its central nervous system. Even considering the limitation of this model to fully reproduce the human UMN disorders, zebrafish offer an excellent alternative vertebrate model for the molecular and genetic dissection of MND mechanisms. Its advantages include the conservation of genome and physiological processes and applicable in vivo tools, including easy imaging, loss or gain of function methods, behavioral tests to examine changes in motor activity, and the ease of simultaneous chemical/drug testing on large numbers of animals. This facilitates the assessment of the environmental origin of MNDs, alone or in combination with genetic traits and putative modifier genes. Positive hits obtained by phenotype-based small-molecule screening using zebrafish may potentially be effective drugs for treatment of human MNDs.

  10. Dietary protein requirements and adaptive advantages in athletes.

    PubMed

    Phillips, Stuart M

    2012-08-01

    Dietary guidelines from a variety of sources are generally congruent that an adequate dietary protein intake for persons over the age of 19 is between 0·8-0·9 g protein/kg body weight/d. According to the US/Canadian Dietary Reference Intakes, the RDA for protein of 0·8 g protein/kg/d is "...the average daily intake level that is sufficient to meet the nutrient requirement of nearly all [~98 %]… healthy individuals..." The panel also states that "...no additional dietary protein is suggested for healthy adults undertaking resistance or endurance exercise." These recommendations are in contrast to recommendations from the US and Canadian Dietetic Association: "Protein recommendations for endurance and strength trained athletes range from 1·2 to 1·7 g/kg/d." The disparity between those setting dietary protein requirements and those who might be considered to be making practical recommendations for athletes is substantial. This may reflect a situation where an adaptive advantage of protein intakes higher than recommended protein requirements exists. That population protein requirements are still based on nitrogen balance may also be a point of contention since achieving balanced nitrogen intake and excretion likely means little to an athlete who has the primary goal of exercise performance. The goal of the present review is to critically analyse evidence from both acute and chronic dietary protein-based studies in which athletic performance, or correlates thereof, have been measured. An attempt will be made to distinguish between protein requirements set by data from nitrogen balance studies, and a potential adaptive 'advantage' for athletes of dietary protein in excess of the RDA.

    2004-01-01

    Published data related with comparison studies of safety, efficiency and some other properties of cold-adapted live influenza vaccine (LIV) and of inactivated influenza vaccine (IIV) are analyzed. LIV and IIV do not differ by systemic reactions after administration; however, it is not ruled out that there can be unfavorable reactions in vaccination of persons with allergy to the chicken-embryo proteins as well as in cases of persistence/reversion of cold-adapted strain observed in vaccination of persons with primary impairments of the immune system. There are no convincing data, up to now, on that LIV is superior to IIV in coping with influenza pandemics. The efficiency of LIV and IIV for children aged 3 years and more and for healthy adults is virtually identical. Additional controllable field comparative studies of LIV and IIV efficiency in immunization of elderly persons are needed. Limited data on LIV efficiency for children aged 2 months and more were obtained. The need in a 2-stage vaccination of all age group with the aim of ensuring responses to all 3 LIV components is, certainly, a LIV disadvantage. In case of IIV, the 2-stage vaccination is needed only for persons who were not ill with influenza. The intranasal LIV administration has, from the practical and psychological standpoints, an advantage before the IIV administration by syringe. The ability of LIV to protect from the drift influenza-virus variations could be its advantage before IIV; still, more research is needed to verify it. Transplantable cell lines meeting the WHO requirements could be an optimal substrate for the production of LIV and IIV. Children are the optimal age group for influenza prevention by cold-adapted LIV, whereas, IIV fits better for vaccination of adults and elderly persons.

    Precipitation-strengthened, nickel-based superalloys are widely used in the aerospace and energy industries due to their excellent environmental resistance and outstanding mechanical properties under extreme conditions. Powder-bed additive manufacturing (AM) technologies offer the potential to revolutionize the processing of superalloy turbine components by eliminating the need for extensive inventory or expensive legacy tooling. Like selective laser melting (SLM), electron beam melting (EBM) constructs three-dimensional dense components layer-by-layer by melting and solidification of atomized, pre-alloyed powder feedstock within 50-200 micron layers. While SLM has been more widely used for AM of nickel alloys like 718, EBM offers several distinct advantages, such as less retained residual stress, lower risk of contamination, and faster build rates with multiple-electron-beam configurations. These advantages are particularly attractive for turbine disks, for which excessive residual stress and contamination can shorten disk life during high-temperature operation. In this presentation, we will discuss the feasibility of fabricating disk superalloy components using EBM AM. Originally developed using powder metallurgy forging processing, disk superalloys contain a higher refractory content and precipitate volume fraction than alloy 718, thus making them more prone to thermal cracking during AM. This and other challenges to produce homogeneous builds with desired properties will be presented. In particular, the quality of lab-scale samples fabricated via a design of experiments, in which the beam current, build temperature, and beam velocity were varied, will be summarized. The relationship between processing parameters, microstructure, grain orientation, and mechanical response will be discussed.

    2014-01-01

    Additive Manufacturing of metallic components for aerospace applications offers many advantages over traditional manufacturing techniques. As a new technology, many aspects of its widespread utilization remain open to investigation. Among these are the cleaning processes that can be used for post finishing of parts and measurements to verify effectiveness of the cleaning processes. Many cleaning and drying processes and measurement methods that have been used for parts manufactured using conventional techniques are candidates that may be considered for cleaning and verification of additively manufactured parts. Among these are vapor degreasing, ultrasonic immersion and spray cleaning, followed by hot air drying, vacuum baking and solvent displacement drying. Differences in porosity, density, and surface finish of additively manufactured versus conventionally manufactured parts may introduce new considerations in the selection of cleaning and drying processes or the method used to verify their effectiveness. This presentation will review the relative strengths and weaknesses of different candidate cleaning and drying processes as they may apply to additively manufactured metal parts for aerospace applications. An ultrasonic cleaning technique for exploring the cleanability of parts will be presented along with an example using additively manufactured Inconel 718 test specimens to illustrate its use. The data analysis shows that this ultrasonic cleaning approach results in a well-behaved ultrasonic cleaning/extraction behavior. That is, it does not show signs of accelerated cavitation erosion of the base material, which was later confirmed by neutron imaging. In addition, the analysis indicated that complete cleaning would be achieved by ultrasonic immersion cleaning at approximately 5 minutes, which was verified by subsequent cleaning of additional parts.

    The technology of 3D printing is conquering the world and awakens the interest of many users in the most varying of applications. New formulation approaches for photo-sensitive thiol-ene resins in combination with various printing technologies, like stereolithography (SLA), projection based printing/digital light processing (DLP) or two-photon polymerization (TPP) are presented. Thiol-ene polymerizations are known for its fast and quantitative reaction and to form highly homogeneous polymer networks. As the resins are locally and temporally photo-curable the polymerization type is very promising for 3D-printing. By using suitable wavelengths, photoinitiator-free fabrication is feasible for single- and two photon induced polymerization. In this paper divinyl ethers of polyethylene glycols in combination with star-shaped tetrathiols were used to design a simple test-system for photo-curable thiol-ene resins. In order to control and improve curing depth and lateral resolution in 3D-polymerization processes, either additives in chemical formulation or process parameters can be changed. The achieved curing depth and resolution limits depend on the applied fabrication method. While two-/multiphoton induced lithography offers the possibility of micron- to sub-micron resolution it lacks in built-up speed. Hence single-photon polymerization is a fast alternative with optimization potential in sub-10-micron resolution. Absorber- and initiator free compositions were developed in order to avoid aging, yellowing and toxicity of resulting products. They can be cured with UV-laser radiation below 300 nm. The development at Fraunhofer ILT is focusing on new applications in the field of medical products and implants, technical products with respect to mechanical properties or optical properties of 3D-printed objects.

    Helium ion microscopy (HIM) has been used to study nanopatterns formed in block copolymer (BCP) thin films. Owing to its' small spot size, minimal forward scattering of the incident ion and reduced velocity compared to electrons of comparable energy, HIM has considerable advantages and provides pattern information and resolution not attainable with other commercial microscopic techniques. In order to realize the full potential of BCP nanolithography in producing high density ultra-small features, the dimensions and geometry of these BCP materials will need to be accurately characterized through pattern formation, development and pattern transfer processes. The preferred BCP pattern inspection techniques (to date) are principally atomic force microscopy (AFM) and secondary electron microscopy (SEM) but suffer disadvantages in poor lateral resolution (AFM) and the ability to discriminate individual polymer domains (SEM). SEM suffers from reduced resolution when a more surface sensitive low accelerating voltage is used and low surface signal when a high accelerating voltage is used. In addition to these drawbacks, SEM can require the use of a conductive coating on these insulating materials and this reduces surface detail as well as increasing the dimensions of coated features. AFM is limited by the dimensions of the probe tip and a skewing of lateral dimension results. This can be eliminated through basic geometry for large sparse features, but when dense small features need to be characterized AFM lacks reliability. With this in mind, BCP inspection by HIM can offer greater insight into block ordering, critical dimensions and, critically, line edge roughness (LER) a critical parameter whose measurement is well suited to HIM because of its' enhanced edge contrast. In this work we demonstrate the resolution capabilities of HIM using various BCP systems (lamellar and cylinder structures).

    The objective of this study was to determine if volumetric modulated arc therapy (VMAT) offers advantages over intensity modulated radiotherapy (IMRT) for complex brain gliomas and evaluate the role of an additional partial arc. Twelve patients with glioma involving critical organs at risk (OAR) were selected [six low grade brainstem glioma (BG) and six glioblastoma (GB) cases]. BGs were prescribed 54 Gy/30 fractions (frx), and GB treated to 50 Gy/30 frx to a lower dose PTV (PTV50) with a simultaneous integrated boost delivering a total dose of 60 Gy/30 frx to a higher dose PTV (PTV60). VMAT was planned with a single arc (VMAT1) and with an additional coplanar partial arc spanning 90° (VMAT2). We observed VMATI improving the PTV equivalent uniform dose (EUD) for BG cases (p=0.027), improving the V95 for the PTV50 in GB cases (p=0.026) and resulting in more conformal GB plans (p=0.008) as compare to IMRT. However, for the GB PTV60, IMRT achieved favorable V95 over VMAT1 and VMAT2 (0.0046 and 0.008, respectively). The GB total integral dose (ID) was significantly lower with VMAT1 and VMAT2 (p=0.049 and p=0.006, respectively). Both VMAT1 and VMAT2 reduced the ID, however, only at the 5 Gy threshold for BG cases (p=0.011 and 0.005, respectively). VMAT achieved a lower spinal cord maximum dose and EUD for BG cases and higher optic nerve doses, otherwise no significant differences were observed. VMAT1 yielded the fastest treatment times and least MU. We conclude that VMAT offers faster treatment delivery for complex brain tumors while maintaining similar dosimetric qualities to IMRT. Selective dosimetric advantages in terms of spinal cord sparing and lowering the ID are observed favoring the use of an additional coplanar partial arc.

  9. Disconnects between popular discourse and home advantage research: what can fans and media tell us about the home advantage phenomenon?

    PubMed

    Smith, D Randall

    2005-04-01

    Many of the factors identified as influencing the home advantage have an underlying social basis, presumably through the influence exerted by the home crowd. Beliefs in the home advantage and the causes of that advantage also have a social basis: sports coverage and fan discourse focus on some aspects of the phenomenon at the expense of others. This paper compares home advantage research with the use of the concept in media narratives and fan Intemet postings. While there are many similarities across sources, the findings suggest three major differences. Fans, and to a lesser extent the media, (1) focus almost exclusively on winning as the evidence for a home advantage, (2) see crowd noise as the main factor for the home advantage, and (3) treat the phenomenon as much more transient than is suggested by academic studies. I identify several features of the phenomenon that facilitate popular views of the home advantage and suggest how future research may benefit from incorporating those views.

  10. Health Benefits Offer Rates: Is There a Nonresponse Bias?

    PubMed Central

    Pickreign, Jeremy D; Gabel, Jon R

    2005-01-01

    Objective To determine whether a nonresponse bias exists in the offer rate for health benefits in firms with fewer than 50 workers and to present a simple adjustment to correct for observed bias. Data Sources The 2003 Employer Health Benefits Survey (EHBS) conducted by the Kaiser Family Foundation and Health Research and Educational Trust, and a follow-up survey of nonrespondents to the 2003 EHBS. Study Design We conducted a follow-up survey to the 2003 EHBS to collect health benefits offering data from firms with fewer than 50 workers. We used McNemar's test to verify that the follow-up survey provided results comparable to the EHBS, and t-tests were used to determine nonresponse bias. We applied a simple weighting adjustment to the EHBS. Data Collection The data for both the EHBS and the follow-up survey were collected by the same survey research firm. The EHBS interviews the person most knowledgeable about the firm's health benefits, while the follow-up survey interviews the first person who answers the telephone whether they are the most knowledgeable or not. Principal Findings Firms with 3–9 workers were more likely to exhibit a bias than were firms with 10–24 workers and 25–49 workers. Although the calculated bias for each size category was not significant, there is sufficient evidence to warrant caution when reporting offer rates. Conclusions Survey nonresponse in the EHBS produces an upward bias on estimates for the offer rates of small firms. Although not significant, this upward bias is because of nonresponse by small firms that do not offer health benefits. Our research is limited in that we only control for differences in the size of the firm. PMID:15762899

  11. School meals in French secondary state schools: Do national recommendations lead to healthier nutrition on offer?

    PubMed

    Bertin, Mélanie; Lafay, Lionel; Calamassi-Tran, Gloria; Volatier, Jean-Luc; Dubuisson, Carine

    2012-02-01

    To improve the dietary offering in schools, the French authorities published recommendations on nutrition in 1999, which were then revised in 2007. The aim of the present study was to assess the nutritional offering in secondary school meals and the extent to which the recommendations promote balanced nutritional offerings. In 2005, a national survey was conducted on a representative sample of secondary schools, either administrated by the Ministry of Education (ES) or the Ministry of Agriculture (AS). Information on school-catering organisation and twenty consecutive meals was collected from each of the 707 secondary schools surveyed. Nutritional composition was estimated according to the French food composition database. Univariate and multivariate analyses were used to investigate the impact of food-group frequency guidelines (FFG) on nutritional offering. It was found that 15 and 26 % of ES and AS schools, respectively, had high compliance with the FFG, at lunch. Macronutrient content was unbalanced in ES school lunches in which 42·8 % lipids, 21·5 % proteins and 35·7 % carbohydrates contributed to the energy. Nevertheless, proper offerings in Fe, Ca and vitamin C content were observed. In addition, a lower offering in lipids and a higher offering in proteins, Ca, vitamin C and Fe were found when the FFG were applied (P < 0·001). Similar results were found for AS schools. This paper confirms the effectiveness of FFG in providing nutritionally balanced school meals. However, others measures such as nutrition promotion and actions to improve children's food habits have to be introduced to make the recommendations more effective and easier to understand.

  12. Older Adults Make Less Advantageous Decisions than Younger Adults: Cognitive and Psychological Correlates

    Fein, George; McGillivray, Shannon; Finn, Peter

    2007-01-01

    This study tested the hypotheses that older adults make less advantageous decisions than younger adults on the Iowa gambling task (IGT). Less advantageous decisions, as measured by the IGT, are characterized by choices that favor larger versus smaller immediate rewards, even though such choices may result in long-term negative consequences. The IGT, and measures of neuropsychological function, personality, and psychopathology were administered to 164 healthy adults 18–85 years of age. Older adults performed less advantageously on the IGT compared with younger adults. Additionally, a greater number of older adult’s IGT performances were classified as ‘impaired’ when compared to younger adults. Less advantageous decisions were associated with obsessive symptoms in older adults and with antisocial symptoms in younger adults. Performance on the IGT was positively associated with auditory working memory and psychomotor function in young adults, and in immediate memory in older adults. PMID:17445297

  17. Plant circadian clocks increase photosynthesis, growth, survival, and competitive advantage.

    PubMed

    Dodd, Antony N; Salathia, Neeraj; Hall, Anthony; Kévei, Eva; Tóth, Réka; Nagy, Ferenc; Hibberd, Julian M; Millar, Andrew J; Webb, Alex A R

    2005-07-22

    Circadian clocks are believed to confer an advantage to plants, but the nature of that advantage has been unknown. We show that a substantial photosynthetic advantage is conferred by correct matching of the circadian clock period with that of the external light-dark cycle. In wild type and in long- and short-circadian period mutants of Arabidopsis thaliana, plants with a clock period matched to the environment contain more chlorophyll, fix more carbon, grow faster, and survive better than plants with circadian periods differing from their environment. This explains why plants gain advantage from circadian control.

  18. Unique Offerings of the ISS as an Earth Observing Platform

    NASA Technical Reports Server (NTRS)

    Cooley, Victor M.

    2013-01-01

    The International Space Station offers unique capabilities for earth remote sensing. An established Earth orbiting platform with abundant power, data and commanding infrastructure, the ISS has been in operation for twelve years as a crew occupied science laboratory and offers low cost and expedited concept-to-operation paths for new sensing technologies. Plug in modularity on external platforms equipped with structural, power and data interfaces standardizes and streamlines integration and minimizes risk and start up difficulties. Data dissemination is also standardized. Emerging sensor technologies and instruments tailored for sensing of regional dynamics may not be worthy of dedicated platforms and launch vehicles, but may well be worthy of ISS deployment, hitching a ride on one of a variety of government or commercial visiting vehicles. As global acceptance of the urgent need for understanding Climate Change continues to grow, the value of ISS, orbiting in Low Earth Orbit, in complementing airborne, sun synchronous polar, geosynchronous and other platform remote sensing will also grow.

  19. On the Shallow Processing (Dis)Advantage: Grammar and Economy

    PubMed Central

    Koornneef, Arnout; Reuland, Eric

    2016-01-01

    In the psycholinguistic literature it has been proposed that readers and listeners often adopt a “good-enough” processing strategy in which a “shallow” representation of an utterance driven by (top-down) extra-grammatical processes has a processing advantage over a “deep” (bottom-up) grammatically-driven representation of that same utterance. In the current contribution we claim, both on theoretical and experimental grounds, that this proposal is overly simplistic. Most importantly, in the domain of anaphora there is now an accumulating body of evidence showing that the anaphoric dependencies between (reflexive) pronominals and their antecedents are subject to an economy hierarchy. In this economy hierarchy, deriving anaphoric dependencies by deep—grammatical—operations requires less processing costs than doing so by shallow—extra-grammatical—operations. In addition, in case of ambiguity when both a shallow and a deep derivation are available to the parser, the latter is actually preferred. This, we argue, contradicts the basic assumptions of the shallow–deep dichotomy and, hence, a rethinking of the good-enough processing framework is warranted. PMID:26903897

  20. Advantages and challenges of dissimilar materials in automotive lightweight construction

    NASA Astrophysics Data System (ADS)

    Weberpals, Jan-Philipp; Schmidt, Philipp A.; Böhm, Daniel; Müller, Steffen

    2015-03-01

    The core of future automotive lightweight materials is the joining technology of various material mixes. The type of joining will be essential, particularly in electrified propulsion systems, especially as an improved electrical energy transmission leads to a higher total efficiency of the vehicle. The most evident parts to start the optimization process are the traction battery, the electrical performance modules and the engines. Consequently aluminum plays a very central role for lightweight construction applications. However, the physical-technical requirements of components often require the combination with other materials. Thus the joining of mixed material connections is an essential key technology for many of the current developments, for example in the areas E-Mobility, solar energy and lightweight construction. Due to these advantages mixed material joints are already established in the automotive industry and laser beam remote welding is now a focus technology for mixed material connections. The secret of the laser welding process with mixed materials lies within the different areas of the melting phase diagram depending on the mixing ratio and the cooling down rate. According to that areas with unwanted, prim, intermetallic phases arise in the fusion zone. Therefore, laser welding of mixed material connections can currently only be used with additional filler in the automotive industry.

  1. Face context advantage explained by vernier and separation discrimination acuity.

    PubMed

    Vesker, Michael; Wilson, Hugh R

    2012-01-01

    Seeing facial features in the context of a full face is known to provide an advantage for perception. Using an interocular separation perception task we confirmed that seeing eyes within the context of a face improves discrimination in synthetic faces. We also show that this improvement of the face context can be explained using the presence of individual components of the face such as the nose mouth, or head-outline. We demonstrate that improvements due to the presence of the nose, and head-outline can be explained in terms of two-point separation measurements, obeying Weber's law as established in the literature. We also demonstrate that performance improvements due to the presence of the mouth can be explained in terms of Vernier acuity judgments between eye positions and the corners of the mouth. Overall, our study shows that the improvements in perception of facial features due to the face context effect can be traced to well understood basic visual measurements that may play a very general role in perceptual measurements of distance. Deficiencies in these measurements may also play a role in prosopagnosia. Additionally, we show interference of the eyebrows with the face-inversion effect for interocular discrimination.

  2. Multi-core advantages for mask data preparation

    NASA Astrophysics Data System (ADS)

    Yeap, Johnny; Nogatch, John

    2009-04-01

    Smaller design pattern feature sizes continue to increase mask data file sizes, which increases mask data processing (MDP) times. To satisfy the need for faster turn-around-time, MDP has progressively migrated from single-computer computation, to multi-threading, and then to distributed processing on multiple computers. The availability of low cost multi-core processors can be used advantageously to reduce Mask Data Preparation runtime. Compared to single core processors, multi-core processor have higher performance, however, total available memory and I/O bandwidth need to be increased proportionally with the additional cores. Memory per core and available I/O bandwidth limit the maximum number of cores that can be effective with distributed processing. When a single job is broken down to 2 or more tasks, the granularity of the tasks influences the efficiency of the processing. Smaller tasks allow for smaller memory footprint, better distribution of tasks and increased scalability, but increase input file access time and reduce output data compaction. By choosing a combination of multi-threading and distributed processing, faster run-time and better scalability can be achieved, as compared to either technique alone. The optimal configuration depends on the number of cores per processor, number of processors and memory per core.

  3. Hiding effort to gain a competitive advantage: Evidence from China.

    PubMed

    Zhao, Li; Heyman, Gail D

    2016-06-06

    Previous studies with Western populations have shown that adolescents' tendency to downplay their academic effort is affected by two kinds of motives: ability-related motives (e.g., to appear competent) and social approval motives (e.g., to be popular). In this research, we test for the presence of additional competition-related motives in China, a culture placing strong emphasis on academic competition. Study 1 (N = 150) showed that, in response to a scenario in which a hard-working high-school junior hid effort from classmates, the most highly endorsed explanation was "to influence others to work less hard to maintain a competitive advantage." Study 2 (N = 174) revealed that competition-related explanations were endorsed relatively more often when the speaker and audience had similar academic rankings. This tendency was most evident when both speaker and audience were top performers, and when this was the case, participants' desire to demonstrate superiority over others was a positive predictor of endorsement of competition-related motives. Study 3 (N = 137) verified that competition-related motives were more strongly endorsed among Chinese participants than U.S.

  4. Epistasis and the selective advantage of sex and recombination

    NASA Astrophysics Data System (ADS)

    de Oliveira, Viviane M.; da Silva, Juliana K.; Campos, Paulo R. A.

    2008-09-01

    The understanding of the central mechanisms favoring sex and recombination in real populations is one of the fundamental issues in evolutionary biology. Based on a previous stochastic formulation for the study of sex, here we aim to investigate the conditions under which epistasis favors the fixation of the sexual mode of reproduction in a given population. In addition, we try to identify the evolutionary forces which contribute to this process. One considers a finite population model which assumes the existence of a recombination modifier allele that can activate the recombination mechanism. We have found that sex is very little favored in a scenario of antagonistic epistasis, and this advantage only occurs in a narrow range of values of the selection coefficient sd . On the other hand, synergistic epistasis favors recombination in a very broad domain. However, the major mechanism contributing to the spreading of the modifier allele depends on the range of values of sd . At large sd , background selection favors recombination since it increases the efficacy of selection, while at low sd Muller’s ratchet is the leading mechanism.

  5. [Advantages and disadvantages of outsourcing hospital microbiological testings].

    PubMed

    Komatsu, Masaru

    2011-10-01

    In Japan, laws and ordinances were enforced to relax the regulation of the clinical laboratory setting in hospitals by revising the law of medical institutions in 2001. For this reason, outsourcing hospital microbiological testing, particularly by medium- or small-sized hospitals, was encouraged. The advantage of outsourcing microbiological testing is promotion of an efficient hospital management by cost saving. In contrast, the disadvantages are as follows: deterioration of specimen quality by extension of transportation time, delay in reporting by an independent laboratory compared with that by a hospital-based laboratory; this report is generally obtained within 1 or 2 days, difficulty and lack of communication between the laboratory staff and physician, and deterioration of the value of the microbiology report and the quality of the infection control system in a hospital. In addition to performing profit-related maintenance, independent laboratories should strive hard to maintain the same quality as that of a laboratory registered in a hospital. Furthermore, the new role of independent laboratories demands them to have a system allowing instant communication of information regarding the crisis control of infectious diseases to a hospital.

  6. Securitizing receivables offers low-cost financing option.

    Securitization began in the 1980s with mortgage payments, auto loans, and credit card debt being pooled and used as collateral for securities offerings. More recently, healthcare providers have securitized accounts receivables to obtain low-cost, off-balance-sheet financing. As the need to both raise capital and contain costs grows in health care, providers likely will make increased use of this financing method.

    Objective Drug use has been linked empirically with aggression and violence among youth in national and State of Hawai`i samples. However, the nature of this link and its implications for prevention are unclear. Therefore, this paper explores the intersection of drugs with aggression and violence by using the drug offer context as the unit of analysis. Method Native Hawaiian youth are sampled because substance use rates tend to be higher and onset tends to be earlier than their non-Hawaiian peers. Fourteen sex-specific focus group discussions were held with rural Native Hawaiian middle school students (N=64). Students discussed what they thought they would do in terms of drug refusal strategies in a variety of drug offer contexts. Results While aggression and violence were perceived to be socially inappropriate, students nonetheless felt drug use would be less socially competent. Narrative analyses indicated aggression and violence were perceived to function as potential drug refusal strategies. As proximal drug resistance, aggression and violence perpetration served as an immediate deterrent to the drug offerer, and thus drug use. As distal drug resistance, victimization served as a rationale for avoiding drug using contexts. Conclusions Implications are discussed in terms of prevention policy and practice, specifically in terms of a school-based prevention curriculum. Future research in Hawaiian epistemology and gendered approaches are warranted. PMID:24564559

    ABSTRACT OBJECTIVE To evaluate whether the support offered by maternity hospitals is associated with higher prevalences of exclusive and predominant breastfeeding. METHODS This is a cross-sectional study including a representative sample of 916 infants less than six months who were born in maternity hospitals, in Ribeirao Preto, Sao Paulo, Southeastern Brazil, 2011. The maternity hospitals were evaluated in relation to their fulfillment of the Ten Steps to Successful Breastfeeding. Data were collected regarding breastfeeding patterns, the birth hospital and other characteristics. The individualized effect of the study factor on exclusive and predominant breastfeeding was analyzed using Poisson multiple regression with robust variance. RESULTS Predominant breastfeeding tended to be more prevalent when the number of fulfilled steps was higher (p of linear trend = 0.057). The step related to not offering artificial teats or pacifiers to breastfed infants and that related to encouraging the establishment of breastfeeding support groups were associated, respectively, to a higher prevalence of exclusive (PR = 1.26; 95%CI 1.04;1.54) and predominant breastfeeding (PR = 1.55; 95%CI 1.01;2.39), after an adjustment was performed for confounding variables. CONCLUSIONS We observed a positive association between support offered by maternity hospitals and prevalences of exclusive and predominant breastfeeding. These results can be useful to other locations with similar characteristics (cities with hospitals that fulfill the Ten Steps to Successful Breastfeeding) to provide incentive to breastfeeding, by means of promoting, protecting and supporting breastfeeding in maternity hospitals.

  15. Referee bias contributes to home advantage in English Premiership football.

    2007-09-01

    Officiating bias is thought to contribute to home advantage. Recent research has shown that sports with subjective officiating tend to experience greater home advantage and that referees' decisions can be influenced by crowd noise, but little work has been done to examine whether individual referees vary in their home bias or whether biased decisions contribute to overall home advantage. We develop an ordinal regression model to determine whether various measures of home advantage are affected by the official for the match and by crowd size while controlling for team ability. We examine 5244 English Premier League (EPL) match results involving 50 referees and find that home bias differs between referees. Individual referees give significantly different levels of home advantage, measured as goal differential between the home and away teams, although the significance of this result depends on one referee with a particularly high home advantage (an outlier). Referees vary significantly and robustly in their yellow card and penalty differentials even excluding the outlier. These results confirm that referees are responsible for some of the observed home advantage in the EPL and suggest that home advantage is dependent on the subjective decisions of referees that vary between individuals. We hypothesize that individual referees respond differently to factors such as crowd noise and suggest further research looking at referees' psychological and behavioural responses to biased crowds.

  17. Joint inversion of MT data with GTF and HMT data: Main advantages from a synthetic case study and real data

    2015-12-01

    In this work we assess the main advantages of complementing the standard magnetotelluric (MT) impedance tensor (Z) response with inter-station horizontal magnetic tensor (HMT) and geomagnetic transfer function (GTF) responses. Results were obtained from constraining the subsurface beneath a MT profile in a 3-D environment using distorted synthetic responses and real data. From the synthetic case study four main improvements were observed when performing joint inversion of Z, HMT and GTF data simultaneously, instead of only inverting the commonly used Zdata: (1) superior precision in the characterization of the electrical resistivity values of the anomalies below and outside the profile; (2) the potential to recover high electrical resistivity anomalies that are poorly recovered by using MT responses alone; (3) improvement in the characterization of the bottom and lateral boundaries of the anomalies with low electrical resistivity; and (4) superior imaging of the continuity of structures with low electrical resistivity. A corresponding inversion comparison was performed using real responses from Clare Basin (Co. Clare, Ireland) acquired during summer of 2014 within the IRECCSEM project (www.ireccsem.ie). A total of 140 sites were acquired, including audiomagnetotellurics (AMT) and broadband magnetotelluric (BBMT) time series data. The results obtained undertaking a joint inversion of Z, GTF and HMT data corroborate the results observed in the synthetic study. In addition, when confronted the results of the Clare Basin area with independent geological and geophysical data, the geoelectrical models show higher resolution when HMT and GTF data are included in the inversion process. The observed advantages offer new opportunities for the MT method by making the results from a MT profile in a 3-D environment more believable, supporting the possibility of high-resolution studies without necessarily expending a large amount of economical and computational resources.

    Tooth movement may be achieved by the use of sequential positioners made by altering tooth positions on set-up models to simulate progress of treatment. The principle is based upon Kesling's positioner concept of 1945, though its subsequent application to splint therapy was labour intensive and did not result in precise tooth movement. Invisalign was developed by Align Technology, Inc (Santa Clara, CA, USA) in 1997 by applying 3-D imaging technology to overcome these problems, and permitting customization on a large scale. Their system offers significant advantages, but still suffers from limitations which are discussed in this article.

    The high voltage solar array (HVSA) offers improvements in efficiency, weight, and reliability for the electric propulsion power system. The basic HVSA technology involves designing the solar array to deliver power in the form required by the ion thruster. This paper delves into conventional power processes and problems associated with ion thruster operation using SERT II experience for examples. In this light, the advantages of the HVSA concept for electric propulsion are presented. Tests conducted operating the SERT II thruster system in conjunction with HVSA are discussed. Thruster operation was observed to be normal and in some respects improved.

    The Automated Container Offering System (TACOS) is a cargo booking assistant currently being fielded in the International Traffic Directorate of the Military Traffic Management Command (MTMC). The expert system automates the selection process for type and size of SEAVAN containers, ports, carrier, and ship for containerized military cargo moving from the continental US to Europe. It is designed to perform all processing on simple cases and provide assistance to the human booker on complex cases. MTMC processes requests for {approximately}1000 containers per week on these routes. This paper is a case history which describes factors guiding development of TACOS to illustrate several themes which occur in other (military) logistics expert system projects.

Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limitations to establishing alternative energy production at airports, such as ensuring these facilities do not create wildlife attractants or other hazards. However, with careful planning, locating alternative energy projects at airports could help mitigate many of the challenges currently facing policy makers, developers, and conservationists.

    There is a great need for engineered vascular grafts among patients with cardiovascular diseases who are in need of bypass therapy and lack autologous healthy blood vessels. In addition, because of the severe worldwide shortage of organ donors, there is an increasing need for engineered vascularized tissue constructs as an alternative to organ transplants. Additive manufacturing (AM) offers great advantages and flexibility of fabrication of cell-laden, multimaterial, and anatomically shaped vascular grafts and vascularized tissue constructs. Various inkjet-, extrusion-, and photocrosslinking-based AM techniques have been applied to the fabrication of both self-standing vascular grafts and porous, vascularized tissue constructs. This review discusses the state-of-the-art research on the use of AM for vascular applications and the key criteria for biomaterials in the AM of both acellular and cellular constructs. We envision that new smart printing materials that can adapt to their environment and encourage rapid endothelialization and remodeling will be the key factor in the future for the successful AM of personalized and dynamic vascular tissue applications.

    For over four decades, it has been possible to offer prenatal diagnostic testing for fetal abnormalities. Prenatal testing is now available for a wide range of monogenic disorders as well as chromosomal abnormalities and should be provided within the ethical framework of informed consent and autonomous choice. However, there are no published guidelines for health professionals from varied disciplines who offer prenatal diagnosis (PND) in a range of possible settings including departments of maternity, obstetrics and clinical genetics. We used an Expert Group technique to develop a set of guidelines for provision of prenatal diagnostic services. Thirteen European health professionals, all experts in PND, participated in a workshop to develop the guidelines, which were then subjected to a wide consultation process. The objective of PND was defined as providing prenatal diagnostic testing services (for genetic conditions) that enable families to make informed choices consistent with their individual needs and values and which support them in dealing with the outcome of such testing. General principles, logistical considerations, clinical care and counselling topics are all described and are equally applicable to invasive and non-invasive testing. These guidelines provide a framework for ethical clinical care; however, they are flexible enough to enable practitioners to adapt them to their particular setting. Ideally, an individualised approach to each family is required to ensure autonomous choice and informed consent regarding prenatal diagnostic testing within the local ethical and legal framework.

Considerations in materials selection and pathways to forming hybrid circuits and devices must demonstrate useful electronic function; must enable integration; and must complement the complex shape, low cost, high volume, and high functionality of structural but generally electronically passive additively manufactured components. This article reviews several emerging technologies being used in industry and research/development to provide integration advantages of fabricating multilayer hybrid circuits or devices. First, we review a maskless, noncontact, direct write (DW) technology that excels in the deposition of metallic colloid inks for electrical interconnects.more » Second, we review a complementary technology, aerosol deposition (AD), which excels in the deposition of metallic and ceramic powder as consolidated, thick conformal coatings and is additionally patternable through masking. As a result, we show examples of hybrid circuits/devices integrated beyond 2-D planes, using combinations of DW or AD processes and conventional, established processes.« less

    A method has been found for enhancing the melt flow of thermoplastic polyimides during processing. A high molecular weight 422 copoly(amic acid) or copolyimide was fused with approximately 0.05 to 5 pct by weight of a low molecular weight amic acid or imide additive, and this melt was studied by capillary rheometry. Excellent flow and improved composite properties on graphite resulted from the addition of a PMDA-aniline additive to LARC-TPI. Solution viscosity studies imply that amic acid additives temporarily lower molecular weight and, hence, enlarge the processing window. Thus, compositions containing the additive have a lower melt viscosity for a longer time than those unmodified.

    New generation flexible ureterorenoscopes offer an improved deflection mechanism and a stiffer sheath compared to their predecessors. We aimed to determine if these improvements in design lead to a higher efficacy in the treatment of nephrolithiasis. Ninety patients with upper urinary tract calculi were included into a retrospective analysis. Twenty-nine cases were treated with the conventional flexible ureterorenoscope (11274 AA, Karl Storz Endoscopy, Germany) and 61 cases were treated with the new generation device (Flex-X, Karl Storz Endoscopy). Patients' and stone characteristics, intraoperative data, treatment success and complications were retrieved from the charts and compared between the two groups. Preoperative data were comparable in both groups. Whereas stone access was also comparable (97 vs. 100%; n.s.), immediate treatment success was significantly higher for the new flexible scope (70 vs. 38%; p = 0.003). For the subgroup of lower pole stones, stone access was possible in 94 versus 100% (n.s.) and treatment success was 31 versus 69% (p = 0.0004) for the conventional and the new generation device, respectively. No major complications were observed, minor complications were comparable in both groups. Our study suggests an advantage of the new generation flexible ureterorenoscopes compared to their predecessors. They offer an increased stone free rate especially in the treatment of lower pole stones. It seems therefore advisable to switch to the latest generation flexible devices.

    Most organizations focus considerable time and energy on reducing operating costs as a way to attain marketplace advantage. This strategy was not inappropriate in the past. To be competitive in the future, however, focus must be placed on other issues, not just cost reduction. The near future will be dominated by service industries, knowledge management, and virtual partnerships, with production optimization and flexibility, innovation, and strong partnerships defining those organizations that attain competitive advantage. Competitive advantage will reside in clarifying the vision and strategic plan, reviewing and redesigning work processes to optimize resources and value-added work, and creating change-ready environments and empowered workforces.

    Third generation high brightness light sources are designed to have low emittance and high current beams, which contribute to higher beam loss rates that will be compensated by Top-Off injection. Shielding for these higher loss rates will be critical to protect the projected higher occupancy factors for the users. Top-Off injection requires a full energy injector, which will demand greater consideration of the potential abnormal beam miss-steering and localized losses that could occur. The high energy electron injection beam produce significantly higher neutron component dose to the experimental floor than lower energy injection and ramped operations. High energy neutrons produced in the forward direction from thin target beam losses are a major component of the dose rate outside the shield walls of the tunnel. The convention has been to provide thicker 90° ratchet walls to reduce this dose to the beam line users. We present an alternate circular shield wall design, which naturally and cost effectively increases the path length for this forward radiation in the shield wall and thereby substantially decreasing the dose rate for these beam losses. Here, this shield wall design will greatly reduce the dose rate to the users working near the front end optical components but will challenge the beam line designers to effectively utilize the longer length of beam line penetration in the shield wall. Additional advantages of the circular shield wall tunnel are that it's simpler to construct, allows greater access to the insertion devices and the upstream in tunnel beam line components, as well as reducing the volume of concrete and therefore the cost of the shield wall.

    Over the past few years, the expansion of general-purpose graphic-processing unit (GPGPU) technology has had a great impact on computational science. GPGPU is the utilization of a graphics-processing unit (GPU) to perform calculations in applications usually handled by the central processing unit (CPU). Use of GPGPUs as a way to increase computational power in the material sciences has significantly decreased computational costs in already highly demanding calculations. A level of the acceleration and parallelization depends on the problem itself. Some problems can benefit from GPU acceleration and parallelization, such as the finite-difference time-domain algorithm (FTDT) and density-functional theory (DFT), while others cannot take advantage of these modern technologies. A number of GPU-supported applications had emerged in the past several years (www.nvidia.com/object/gpu-applications.html). Quantum Espresso (QE) is reported as an integrated suite of open source computer codes for electronic-structure calculations and materials modeling at the nano-scale. It is based on DFT, the use of a plane-waves basis and a pseudopotential approach. Since the QE 5.0 version, it has been implemented as a plug-in component for standard QE packages that allows exploiting the capabilities of Nvidia GPU graphic cards (www.qe-forge.org/gf/proj). In this study, we have examined the impact of the usage of GPU acceleration and parallelization on the numerical performance of DFT calculations. Graphene has been attracting attention worldwide and has already shown some remarkable properties. We have studied an intercalated graphene, using the QE package PHonon, which employs GPU. The term ‘intercalation’ refers to a process whereby foreign adatoms are inserted onto a graphene lattice. In addition, by intercalating different atoms between graphene layers, it is possible to tune their physical properties. Our experiments have shown there are benefits from using GPUs, and we reached an

    Additive manufacturing (AM) offers tremendous promise for the rocket propulsion community. Foundational work must be performed to ensure the safe performance of AM parts. Government, industry, and academia must collaborate in the characterization, design, modeling, and process control to accelerate the certification of AM parts for human-rated flight.

    The 93/43 European Union directive assigns to the food and catering industries the main responsibility for an integrated safety and quality assurance strategy in the food chain. Relying on hazard analysis, followed by design and adoption of control of all critical points and practices ("HACCP"). Hiatus-free compliance with such HACCP-based Codes of Good Practices is to be assessed by monitoring, recording results on process performance charts and gauging such data against experimentally established, attainable and maintainable references ranges ("standards"). Marker microorganisms are a major analytical tool for validating compliance in the sense of the EU directive. They should be expertly chosen amongst microbes usually present in food so that their, whose presence in quantities exceeding predetermined levels point to a lack of microbiological integrity of a food product. This may encompass (i) the potential presence of taxonomically, physiologically and ecologically related pathogens, markers are called index organisms; or else (ii) a lack of process integrity; in this case, markers are termed indicator organisms. The classical index organism was E. coli, introduced in the 1980's to monitor drinking water supplies. It is still used as an appropriate marker to assess the bacteriological safety of raw foods. In the 1920's the coli-aerogenes ("coliform") group was adopted as an indicator to validate the adequate processing, i.e. pasteurization of dairy products. Since the 1950's the entire Enterobacteriaceae taxon is preferred for the latter purpose because it is better defined in determinative sense and includes more organisms of significance. In some food and water supplies, processed for safety, more vigorous or more resistant organisms than the Gram-negative rods are reliable supplementary markers. These include Enterococcus spp., spores of the Clostridium genus, and bacteriophages of E. coli and Bacteroides fragilis mimicking the fate of enteric viruses under particular ecological conditions. Population surveys conducted by the authors provided ranges for epsilon-factors. Those factors were defined as the proportion between colony forming units (cfu) numbers of index organisms and the pathogenic agent to whose potential occurrence they are expected to point. Epsilon factor values obtained for thermotropic Enterobacteriaceae in relation to Salmonella spp. allow the calculation of the probability that the pathogen has been reliably eliminated by the processing of initially contaminated raw materials, when cfu's of the marker organisms remain below a reference range previously fixed.
