Topical tar: Back to the future  

SciTech Connect

The use of medicinal tar for dermatologic disorders dates back to the ancient times. Although coal tar is utilized more frequently in modern dermatology, wood tars have also been widely employed. Tar is used mainly in the treatment of chronic stable plaque psoriasis, scalp psoriasis, atopic dermatitis, and seborrheic dermatitis, either alone or in combination therapy with other medications, phototherapy, or both. Many modifications have been made to tar preparations to increase their acceptability, as some dislike its odor, messy application, and staining of clothing. One should consider a tried and true treatment with tar that has led to clearing of lesions and prolonged remission times. Occupational studies have demonstrated the carcinogenicity of tar; however, epidemiologic studies do not confirm similar outcomes when used topically. This article will review the pharmacology, formulations, efficacy, and adverse effects of crude coal tar and other tars in the treatment of selected dermatologic conditions.

Black Holes at Future Colliders and Beyond: a Topical Review  

E-print Network

One of the most dramatic consequences of low-scale (~1 TeV) quantum gravity in models with large or warped extra dimension(s) is copious production of mini black holes at future colliders and in ultra-high-energy cosmic ray collisions. Hawking radiation of these black holes is expected to be constrained mainly to our three-dimensional world and results in rich phenomenology. In this topical review we discuss the current status of astrophysical observations of black holes and selected aspects of mini black hole phenomenology, such as production at colliders and in cosmic rays, black hole decay properties, Hawking radiation as a sensitive probe of the dimensionality of extra space, as well as an exciting possibility of finding new physics in the decays of black holes.

1. Abstract In this paper, we investigate the effects of future tests on aircraft structural safety, focusing on the numbers of coupon tests and structural element tests. The mean failure stress is assumed to be predicted by a failure criterion (e.g. Tsai-Wu), and the initial distribution of this mean failure stress reflects the uncertainty in the analysis procedure that uses

Reliability based design including future tests and multiagent approaches  

NASA Astrophysics Data System (ADS)

The initial stages of reliability-based design optimization involve the formulation of objective functions and constraints, and building a model to estimate the reliability of the design with quantified uncertainties. However, even experienced hands often overlook important objective functions and constraints that affect the design. In addition, uncertainty reduction measures, such as tests and redesign, are often not considered in reliability calculations during the initial stages. This research considers two areas that concern the design of engineering systems: 1) the trade-off of the effect of a test and post-test redesign on reliability and cost and 2) the search for multiple candidate designs as insurance against unforeseen faults in some designs. In this research, a methodology was developed to estimate the effect of a single future test and post-test redesign on reliability and cost. The methodology uses assumed distributions of computational and experimental errors with re-design rules to simulate alternative future test and redesign outcomes to form a probabilistic estimate of the reliability and cost for a given design. Further, it was explored how modeling a future test and redesign provides a company an opportunity to balance development costs versus performance by simultaneously designing the design and the post-test redesign rules during the initial design stage. The second area of this research considers the use of dynamic local surrogates, or surrogate-based agents, to locate multiple candidate designs. Surrogate-based global optimization algorithms often require search in multiple candidate regions of design space, expending most of the computation needed to define multiple alternate designs. Thus, focusing on solely locating the best design may be wasteful. We extended adaptive sampling surrogate techniques to locate multiple optima by building local surrogates in sub-regions of the design space to identify optima. The efficiency of this method was studied, and the method was compared to other surrogate-based optimization methods that aim to locate the global optimum using two two-dimensional test functions, a six-dimensional test function, and a five-dimensional engineering example.

Theory including future not excluded: Formulation of complex action theory II  

NASA Astrophysics Data System (ADS)

We study a complex action theory (CAT) whose path runs over not only past but also future. We show that, if we regard a matrix element defined in terms of the future state at time TB and the past state at time TA as an expectation value in the CAT, then we are allowed to have the Heisenberg equation, Ehrenfest's theorem, and the conserved probability current density. In addition, we show that the expectation value at the present time t of a future-included theory for large TB - t and large t - TA corresponds to that of a future-not-included theory with a proper inner product for large t - TA. Hence, the CAT with future explicitly present in the formalism and influencing in principle the past is not excluded phenomenologically, because the effects are argued to be very small in the present era. Furthermore, we explicitly derive the Hamiltonian for the future state via a path integral, and confirm that it is given by the Hermitian conjugate of the Hamiltonian for the past state.

Including Impacts of Climate Change in Long-Range Forecasts of Future Tuolumne River Streamflow  

NASA Astrophysics Data System (ADS)

Future streamflow is assessed for the Tuolumne River, a representative watershed in Sierra Nevada Mountains in California that provides 85% of the San Francisco Public Utility Commission's water supply for 2.5 million Bay Area residents and water to 8000 agricultural customers and over 200,000 electrical customers of the Turlock and Modesto Irrigation Districts. The Hydrocomp Forecasting and Analysis Model (HFAM) is a hydrologic simulation model which provides probabilistic inflow forecasts based on a continuous long-term simulation of a watershed driven by a historical meteorological database. The HFAM model is used to assess potential changes in the timing and volume of streamflow by driving the model with a long-term meteorological database that has been altered to represent the future climate in a specific year, for a given climate change scenario. In the Tuolumne, historical trends show increases to daily minimum temperatures but not to daily maximum temperatures. A static meteorological database that represents the current climate condition is generated by removing trends from historical data. Climate change scenarios for paired changes in temperature and precipitation were developed based on the range of predictions by global climate models. For each future climate condition, hourly temperature increases to the static database are calculated that are consistent with historical trends in daily minimum temperatures, while retaining a reasonable daily range in temperatures. Changes in future seasonal and annual probabilistic inflow forecasts are given for the Tuolumne River for each climate change scenario. The results show the importance of using probabilistic methods to assess climate change rather than mean values because impacts are more significant in low streamflow years.

Present-day and future global bottom-up ship emission inventories including polar routes.  

PubMed

We present a global bottom-up ship emission algorithm that calculates fuel consumption, emissions, and vessel traffic densities for present-day (2006) and two future scenarios (2050) considering the opening of Arctic polar routes due to projected sea ice decline. Ship movements and actual ship engine power per individual ship from Lloyd's Marine Intelligence Unit (LMIU) ship statistics for six months in 2006 and further mean engine data from literature serve as input. The developed SeaKLIM algorithm automatically finds the most probable shipping route for each combination of start and destination port of a certain ship movement by calculating the shortest path on a predefined model grid while considering land masses, sea ice, shipping canal sizes, and climatological mean wave heights. The resulting present-day ship activity agrees well with observations. The global fuel consumption of 221 Mt in 2006 lies in the range of previously published inventories when undercounting of ship numbers in the LMIU movement database (40,055 vessels) is considered. Extrapolated to 2007 and ship numbers per ship type of the recent International Maritime Organization (IMO) estimate (100,214 vessels), a fuel consumption of 349 Mt is calculated which is in good agreement with the IMO total of 333 Mt. The future scenarios show Arctic polar routes with regional fuel consumption on the Northeast and Northwest Passage increasing by factors of up to 9 and 13 until 2050, respectively. PMID:20088494

Colorectal endoscopic submucosal dissection: present status and future perspective, including its differentiation from endoscopic mucosal resection.  

PubMed

Endoscopic submucosal dissection (ESD) allows en bloc resection of a lesion, irrespective of the size of the lesion. ESD has been established as a standard method for the endoscopic ablation of malignant tumors in the upper gastrointestinal (GI) tract in Japan. Although the use of ESD for colorectal lesions has been studied via clinical research, ESD is not yet established as a standard therapeutic method for colorectal lesions because colorectal carcinoma has unique pathological, organ specific characteristics that differ radically from those of the esophagus and stomach, and scope handling and control is more difficult in the colorectum than in the upper GI tract. Depending on the efficacy of endoscopic mucosal resection (EMR) and the clinicopathological characteristics of the colorectal tumor, the proposed indications for colorectal ESD are as follows: (1) lesions difficult to remove en bloc with a snare EMR, such as nongranular laterally spreading tumors (particularly the pseudo depressed type), lesions showing a type VI: pit pattern, and large lesions of the protruded type suspected to be carcinoma; (2) lesions with fibrosis due to biopsy or peristasis; (3) sporadic localized lesions in chronic inflammation such as ulcerative colitis; and (4) local residual carcinoma after EMR. Colorectal ESD is currently in the development stage, and a standard protocol will be available in the near future. We hope that colorectal tumors will be efficiently treated by a treatment method appropriately selected from among EMR, ESD, and surgical resection after precise preoperative diagnosis based on techniques such as magnifying colonoscopy.

REVIEWS OF TOPICAL PROBLEMS: Experimental tests of general relativity: recent progress and future directions  

NASA Astrophysics Data System (ADS)

Einstein's general theory of relativity is the standard theory of gravity, especially where the needs of astronomy, astrophysics, cosmology, and fundamental physics are concerned. As such, this theory is used for many practical purposes involving spacecraft navigation, geodesy, and time transfer. We review the foundations of general relativity, discuss recent progress in tests of relativistic gravity, and present motivations for the new generation of high-accuracy tests of new physics beyond general relativity. Space-based experiments in fundamental physics are presently capable of uniquely addressing important questions related to the fundamental laws of nature. We discuss the advances in our understanding of fundamental physics that are anticipated in the near future and evaluate the discovery potential of a number of recently proposed space-based gravitational experiments.

Skin penetration and metabolism of topically applied chemicals in six mammalian species, including man: an in vitro study with benzo(a)pyrene and testosterone  

SciTech Connect

Because viable skin possesses enzyme activities, including those involved in the metabolism of xenobiotics, the extent to which cutaneous metabolism may influence the percutaneous fate of topically applied chemicals in the skin was examined in mammalian skin maintained as short-term organ cultures. Skin samples from mouse, rat, rabbit, guinea pig, marmoset, and man were examined. The results from studies with benzo(a)pyrene (BP) and testosterone showed that, in all species, metabolic viability was a major factor involved in the in vitro skin permeation of surface-applied chemicals. Permeation was accompanied by extensive cutaneous first pass metabolism; both parent compounds and a full spectrum of metabolites were found in the receptor fluid from viable skin preparations. However, in previously frozen nonviable skin preparations, essentially only unchanged parent compounds were detected in the receptor fluid. Permeation of BP and testosterone was highest in mouse skin, and significant species variations in the metabolite profiles were observed. Studies with mouse skin also demonstrated that induction of cutaneous drug-metabolizing enzymes can result in a two- to threefold increase in the in vitro permeation of topical BP, and a significant reduction in permeation was observed when KCN was added to the perfusion medium. These results indicate that diffusional and metabolic processes are intimately involved in the percutaneous fate of surface-applied chemicals. The relative importance of these processes is dependent upon the physicochemical properties of the compounds and the metabolic capabilities of the skin toward the compounds in question. Furthermore, these findings suggest that meaningful in vitro studies on skin absorption should consider both diffusion and cutaneous biotransformation of the applied compound.

Mechanism of Human Tooth Eruption: Review Article Including a New Theory for Future Studies on the Eruption Process  

PubMed Central

Human eruption is a unique developmental process in the organism. The aetiology or the mechanism behind eruption has never been fully understood and the scientific literature in the field is extremely sparse. Human and animal tissues provide different possibilities for eruption analyses, briefly discussed in the introduction. Human studies, mainly clinical and radiological, have focused on normal eruption and gender differences. Why a tooth begins eruption and what enables it to move eruptively and later to end these eruptive movements is not known. Pathological eruption courses contribute to insight into the aetiology behind eruption. A new theory on the eruption mechanism is presented. Accordingly, the mechanism of eruption depends on the correlation between space in the eruption course, created by the crown follicle, eruption pressure triggered by innervation in the apical root membrane, and the ability of the periodontal ligament to adapt to eruptive movements. Animal studies and studies on normal and pathological eruption in humans can support and explain different aspects in the new theory. The eruption mechanism still needs elucidation and the paper recommends that future research on eruption keeps this new theory in mind. Understanding the aetiology of the eruption process is necessary for treating deviant eruption courses. PMID:24688798

The role of natural gas as a primary fuel in the near future, including comparisons of acquisition, transmission and waste handling costs of as with competitive alternatives  

PubMed Central

Natural gas comprises about a quarter of the United States’ energy use. It is more environmentally friendly than oil and coal due to lower carbon dioxide (CO2) emissions per unit, less costly per unit of energy and more readily available domestically in abundant supply. However, due to a number of barriers in the political, infrastructural, pricing and other arenas, the use of natural gas as a significant energy source in the United States has been limited. In our paper, we highlight the favorable qualities of natural gas and its benefits for the consumer, producer, and environment, having compared the costs of the various components of the natural gas business such as drilling and transport to that of coal and oil. Moreover, we touch upon the major issues that have prevented a more prevalent use of the gas, such as the fact that the infrastructure of natural gas is more costly since it is transported though pipelines whereas other energy sources such as oil and coal have flexible systems that use trains, trucks and ships. In addition, the powerful lobbies of the coal and oil businesses, along with the inertia in the congress to pass a national climate change bill further dampens incentives for these industries to invest in natural gas, despite its various attractive qualities. We also include discussions of policy proposals to incentive greater use of natural gas in the future. PMID:22540989

The future of land warfare  

SciTech Connect

Sophisticated new technology and vastly increased firepower mean that future land battles are likely to be very different to those of the past. The Iran-Iraq war and the British experience in the Falklands have shown, however, that factors such as terrain, morale and surprise continue to be of vital importance. This book is a consideration of the likely nature of (and possibilities for) land warfare during the next twenty-five years. It discusses the elements of modern warfare including weapons developments, intelligence, logistics and tactics. The book concludes with speculative predictions of future conflicts. Topics covered include hell on earth: war in the 1970s and 1980s; factors affecting air-land warfare; geography, demography and the major land powers; nuclear; biological; chemical or conventional; operational art of major land powers; weapons platforms, protection, electronic warfare (including laser and charged particle beam weapons); command, control, communications and intelligence; and the nature of future land warfare.

Topical Drug Delivery for Chronic Rhinosinusitis  

PubMed Central

Chronic rhinosinusitis is a multifactorial disorder that may be heterogeneous in presentation and clinical course. While the introduction of endoscopic sinus surgery revolutionized surgical management and has led to significantly improved patient outcomes, medical therapy remains the foundation of long-term care of chronic rhinosinusitis, particularly in surgically recalcitrant cases. A variety of devices and pharmaceutical agents have been developed to apply topical medical therapy to the sinuses, taking advantage of the access provided by endoscopic surgery. The goal of topical therapy is to address the inflammation, infection, and mucociliary dysfunction that underlies the disease. Major factors that impact success include the patient’s sinus anatomy and the dynamics of the delivery device. Despite a growing number of topical treatment options, the evidence-based literature to support their use is limited. In this article, we comprehensively review current delivery methods and the available topical agents. We also discuss biotechnological advances that promise enhanced delivery in the future, and evolving pharmacotherapeutical compounds that may be added to rhinologist’s armamentarium. A complete understand of topical drug delivery is increasingly essential to the management of chronic rhinosinusitis when traditional forms of medical therapy and surgery have failed. PMID:23525506

NASA Astrophysics Data System (ADS)

This study examines the effect of increasing the visual complexity used in computer assisted instruction in general chemistry. Traditional recitation instruction was used as a control for the experiment. One tutorial presented a chemistry topic using 3-D animation showing molecular activity and symbolic representation of the macroscopic view of a chemical phenomenon. A second tutorial presented the same topic but simultaneously presented students with a digital video movie showing the phenomena and 3-D animation showing the molecular view of the phenomena. This experimental set-up was used in two different experiments during the first semester of college level general chemistry course. The topics covered were the molecular effect of heating water through the solid-liquid phase change and the kinetic molecular theory used in explaining pressure changes. The subjects used in the experiment were 236 college students enrolled in a freshman chemistry course at a large university. The data indicated that the simultaneous presentation of digital video, showing the solid to liquid phase change of water, with a molecular animation, showing the molecular behavior during the phase change, had a significant effect on student particulate understanding when compared to traditional recitation. Although the effect of the KMT tutorial was not statistically significant, there was a positive effect on student particulate understanding. The use of computer tutorial also had a significant effect on student attitude toward their comprehension of the lesson.

Identifying Key Priorities for Future Palliative Care Research Using an Innovative Analytic Approach  

PubMed Central

Using an innovative approach, we identified research priorities in palliative care to guide future research initiatives. We searched 7databases (2005–2012) for review articles published on the topics of palliative and hospice–end-of-life care. The identified research recommendations (n = 648) fell into 2 distinct categories: (1) ways to improve methodological approaches and (2) specific topic areas in need of future study. The most commonly cited priority within the theme of methodological approaches was the need for enhanced rigor. Specific topics in need of future study included perspectives and needs of patients, relatives, and providers; underrepresented populations; decision-making; cost-effectiveness; provider education; spirituality; service use; and inter-disciplinary approaches to delivering palliative care. This review underscores the need for additional research on specific topics and methodologically rigorous research to inform health policy and practice. PMID:25393169

Topical Botulinum Toxin  

PubMed Central

Nanotechnology is a rapidly growing discipline that capitalizes on the unique properties of matter engineered on the nanoscale. Vehicles incorporating nanotechnology have led to great strides in drug delivery, allowing for increased active ingredient stability, bioavailability, and site-specific targeting. Botulinum toxin has historically been used for the correction of neurological and neuromuscular disorders, such as torticollis, blepharospasm, and strabismus. Recent dermatological indications have been for the management of axillary hyperhydrosis and facial rhytides. Traditional methods of botulinum toxin delivery have been needle-based. These have been associated with increased pain and cost. Newer methods of botulinum toxin formulation have yielded topical preparations that are bioactive in small pilot clinical studies. While there are some risks associated with topical delivery, the refinement and standardization of delivery systems and techniques for the topical administration of botulinum toxin using nanotechnology is anticipated in the near future.

[Fifty years of research on tuberculosis. Lessons I have learnt during 50 years and topics to be investigated in the future].  

PubMed

I have engaged in the research on tuberculosis for 50 years, and lessons I have learnt during this period could be summarized in the following ten topics. First is great research achievements by our predecessors on the establishment of so-called primary infection theory on the pathogenesis of TB, planning of TB control principles based on the theory and development of new technologies used for TB control, such as mass miniature X-ray examination and BCG vaccination in 1920s and 1930s. TB control law was enforced in 1951, and the modern TB programme was initiated. Second, the field is a treasure house of interesting data. Several interesting data on TB soon after the World War II in Tokyo and a rural area were collected and analyzed from the mass health examination. Third, looking at the increase of tuberculin positivity with age, it was found that the tuberculin negativity decreased as the exponential function of age, and the current concept of the annual risk of TB infection was already developed in late 1940s. It was 18.1% in male and 11.6% in female in Tokyo in late 1940s. Based on this concept, age specific TB mortality was analyzed by the type of TB, and the rates of miliary TB and TB meningitis were similar to the rate of newly infected to the total population, while the rate of all forms could be divided into early and late death as shown in Fig. 1. Fourth, I suffered from TB by myself from 1951 to 1953, receiving first thoracoplasty in two stages under local anaesthesia, then right upper lobectomy and segmentectomy of superior segment of right lower lobe. From this experience, I learnt a lot about the psychology and suffering of TB patients. Fifth, the importance of recognition of real magnitude of the problem in such a disease as TB in which many TB cases did not aware of their disease. The answer to this was the first TB prevalence survey in 1953 using stratified random sampling method, and based on the results of the survey, the mass health examination originally focussed on youth was expanded to the total adult population of Japan. Sixth, TB could be reduced rapidly by applying appropriately planned control programme. In big enterprises, the application of intensive case-finding programme brought about the rapid decline of severe TB cases, contributed to the increase of the productivity of the enterprises, thus to the rapid increase of GDP of whole Japan, and the growing spiral between the improvement of health and the economic development was formed by successful TB control. In addition to the mass health examination, BCG vaccination and spread of appropriate treatment in the original TB control law, the registration and case management system and the more extensive application of hospitalization for infectious cases were introduced in early 1960s. Observing the proportion of TB care expenditure to the national medical expenditure, it was 28% in 1954, and it dropped down to 0.4% in recently as shown in Fig. 2. The decline of TB in Japan during 1950s and 1960s was one of fastest in the world. Seventh, there had been marked differences in the prevalence of TB as well as the coverage and quality of TB programmes in several areas of Japan though it was often said that Japan is homogeneous country. To know the real status in various areas of Japan, a chart to express graphically the magnitude of TB and coverage and quality of TB programmes was developed (Fig. 3), and it was finally refined to the current form. Eighth difficulty in changing existing programmes, and we are grateful for kind cooperation of Niigata Prefecture for making several new attempts. Ninth, it has been needed to observe TB problems from global standpoint, and it was actually done through participation to the bilateral cooperation projects on TB control and conducting the international training courses sponsored by JICA. Tenth, TB is a pertinacious disease. As shown in Fig. (ABSTRACT TRUNCATED) PMID:10944893

Topical microbicides and HIV prevention in the female genital tract.  

PubMed

Worldwide, HIV disproportionately affects women who are often unable to negotiate traditional HIV preventive strategies such as condoms. In the absence of an effective vaccine or cure, chemoprophylaxis may be a valuable self-initiated alternative. Topical microbicides have been investigated as one such option. The first generation topical microbicides were non-specific, broad-spectrum antimicrobial agents, including surfactants, polyanions, and acid buffering gels, that generally exhibited contraceptive properties. After extensive clinical study, none prevented HIV infection, and their development was abandoned. Second generation topical microbicides include agents with selective mechanisms of antiviral activity. Most are currently being used for, or have previously been explored as, drugs for treatment of HIV. The most advanced of these is tenofovir 1% gel: the first topical agent shown to significantly reduce HIV infection by 39% compared to placebo. This review summarizes the evolution of topical microbicides for HIV chemoprophylaxis, highlights important concepts learned, and offers current and future considerations for this area of research.

Topical drug classification.  

PubMed

Current definitions of lotions, gels, creams and ointments vary depending on literature source, market history or traditional use. This often leads to confusion when deciding which dosage form to prescribe and/or purchase. The existing classification of topical dosage forms needs to be re-examined to ensure that definitions for different dosage forms are based on consistent scientific principles and that dosage forms can be distinguished from one another. The purpose of this study is to obtain a scientifically based, systematic classification of dosage forms for topical drugs. A variety of prescription and over-the-counter topical products currently marketed as lotions, gels, creams, and ointments are evaluated using different techniques including rheology (viscosity and shear rate versus shear stress), loss on drying (LOD), specific gravity, surface tension, thermogravimetric analysis (TGA), water absorption, dilution properties, microscopic evaluation, transmittance of visible light, appearance and composition. Rheology is the most discriminating property separating creams and lotions. Water plus volatiles (as measured by LOD) and composition separate ointments and creams. Composition and thermal behavior separate gels from the other dosage forms. Based on these findings, new definitions and a decision tree are presented to assist in the determination of the appropriate nomenclature for a topical dosage form. PMID:15847995

Topics in String Phenomenology  

E-print Network

We consider two questions in string ``phenomenology.'' First, are there any generic string predictions? Second, are there any general lessons which string theory suggests for thinking about low energy models, particularly in the framework of supersymmetry? Among the topics we consider are the squark and slepton spectrum, flavor symmetries, discrete symmetries including $CP$, and Peccei-Quinn symmetries. We also note that in some cases, discrete symmetries can be used to constrain the form of supersymmetry breaking.

Present and future applications of magnetic nanostructures grown by FEBID  

NASA Astrophysics Data System (ADS)

Currently, magnetic nanostructures are routinely grown by focused electron beam induced deposition (FEBID). In the present article, we review the milestones produced in the topic in the past as well as the future applications of this technology. Regarding past milestones, we highlight the achievement of high-purity cobalt and iron deposits, the high lateral resolution obtained, the growth of 3D magnetic deposits, the exploration of magnetic alloys and the application of magnetic deposits for Hall sensing and in domain-wall conduit and magnetologic devices. With respect to future perspectives of the topic, we emphasize the potential role of magnetic nanostructures grown by FEBID for applications related to highly integrated 2D arrays, 3D nanowires devices, fabrication of advanced scanning-probe systems, basic studies of magnetic structures and their dynamics, small sensors (including biosensors) and new applications brought by magnetic alloys and even exchange biased systems.

Resources for the Future: Wholesale Electricity Markets and Policy  

NSDL National Science Digital Library

In this article, Tim Brennan, a senior fellow at Resources for the Future, provides an overview of Wholesale Electricity Markets and Policy. Based in Washington, D.C., Resources for the Future (RFF), is an "independent institute dedicated exclusively to analyzing environmental, energy, and natural resource topics." (See also Scout Report from August 23, 1998.) The article is adapted from a book by Brennan published by RFF. In the article, Brennan discusses the challenges and benefits of "replacing regulation with competition" and provides an overview of the electricity market. He concludes that "while reasons for optimism exist, policy-makers should always keep in mind that electricity's crucial nature and unique characteristics may render it unsuitable for extensive competition."

The Effects of Projected Future Demand Including Very Light Jet Air-Taxi Operations on U.S. National Airspace System Delays as a Function of Next Generation Air Transportation System Airspace Capacity  

NASA Technical Reports Server (NTRS)

This paper presents the results from a study which investigates the potential effects of the growth in air traffic demand including projected Very Light Jet (VLJ) air-taxi operations adding to delays experienced by commercial passenger air transportation in the year 2025. The geographic region studied is the contiguous United States (U.S.) of America, although international air traffic to and from the U.S. is included. The main focus of this paper is to determine how much air traffic growth, including VLJ air-taxi operations will add to enroute airspace congestion and determine what additional airspace capacity will be needed to accommodate the expected demand. Terminal airspace is not modeled and increased airport capacity is assumed.

NASA Technical Reports Server (NTRS)

In the "Path to the Future" presentation held at NASA's Langley Center on March 31, 1999, NASA's Administrator Daniel S. Goldin outlined the future direction and strategies of NASA in relation to the general space exploration enterprise. NASA's Vision, Future System Characteristics, Evolutions of Engineering, and Revolutionary Changes are the four main topics of the presentation. In part one, the Administrator talks in detail about NASA's vision in relation to the NASA Strategic Activities that are Space Science, Earth Science, Human Exploration, and Aeronautics & Space Transportation. Topics discussed in this section include: space science for the 21st century, flying in mars atmosphere (mars plane), exploring new worlds, interplanetary internets, earth observation and measurements, distributed information-system-in-the-sky, science enabling understanding and application, space station, microgravity, science and exploration strategies, human mars mission, advance space transportation program, general aviation revitalization, and reusable launch vehicles. In part two, he briefly talks about the future system characteristics. He discusses major system characteristics like resiliencey, self-sufficiency, high distribution, ultra-efficiency, and autonomy and the necessity to overcome any distance, time, and extreme environment barriers. Part three of Mr. Goldin's talk deals with engineering evolution, mainly evolution in the Computer Aided Design (CAD)/Computer Aided Engineering (CAE) systems. These systems include computer aided drafting, computerized solid models, virtual product development (VPD) systems, networked VPD systems, and knowledge enriched networked VPD systems. In part four, the last part, the Administrator talks about the need for revolutionary changes in communication and networking areas of a system. According to the administrator, the four major areas that need cultural changes in the creativity process are human-centered computing, an infrastructure for distributed collaboration, rapid synthesis and simulation tools, and life-cycle integration and validation. Mr. Goldin concludes his presentation with the following maxim "Collaborate, Integrate, Innovate or Stagnate and Evaporate." He also answers some questions after the presentation.

Future perspectives on space psychology: Recommendations on psychosocial and neurobehavioural aspects of human spaceflight  

NASA Astrophysics Data System (ADS)

Recently the psychological effects of space flight have gained in attention. In uncovering the psychological challenges that individuals and teams can face, we need research options that integrate psychosocial aspects with behavioral, performance, technical and environmental issues. Future perspectives in Space Psychology and Human Spaceflight are reviewed in this paper. The topics covered include psychosocial and neurobehavioural aspects, neurocognitive testing tools, decision making, autonomy and delayed communications, well being, mental health, situational awareness, and methodology. Authors were members of a European Space Agency (ESA) Research Topical Team on Psychosocial and Behavioral Aspects of Human Spaceflight. They discuss the different topics under a common perspective of a theoretical and practical framework, showing interactions, relationships and possible solutions for the different aspects and variables in play. Recommendations for every topic are offered and summarized for future research in the field. The different proposed research ideas can be accomplished using analogs and simulation experiments, short- and long-duration bed rest, and in-flight microgravity studies. These topics are especially important for future Moon and Mars mission design and training.

Letters to Future Generations  

NSDL National Science Digital Library

UNESCO (United Nations Educational, Cultural, and Scientific Organization), an organization composed of 188 Member States, attempts to contribute expertise across all of the sciences to enrich both today and tomorrow's world. In developing Letters to future generations, essays written by 22 world leaders and thinkers, UNESCO has done just that. Addressed to people living in 2050, the letters share reflections and concerns on topics ranging from beauty to biological infections. Kofi Annan, Secretary General of the UN, suggests "a culture of peace," while Rita Colwell, of the National Science Foundation, discusses the benefits of a diverse scientific culture, and Hubert Reeves, an astrophysicist, entreats us to be environmentally aware so we can ensure that a future generation will greet the 21st century. To paraphrase philosopher Fernando Savater, while UNESCO's Letters to future generations may not be a new idea, this "mental registry" is nonetheless thought-provoking.

The Future of Virtual Worlds  

NASA Astrophysics Data System (ADS)

This book, like the May 2008 conference in World of Warcraft, ends with projections toward what the future might hold for virtual worlds. Every chapter thus far has included speculations about future directions, even while standing on data from the past. This last chapter, like the final session of the conference on which it is based, incorporates comments from dozens of participants into a stream of ideas. We have edited selected comments together with the panel's contributions. Our intention is to provide a portal from this book into a wider virtual community comprising researchers and residents in virtual worlds. The discussion surveys many recent lines of development, some of which have already been surveyed in scientific and historical literature, or by journalists (Au 2008; Castronova 2007; Guest 2007; Ludlow and Wallace 2007). Yet, many of the topics here have not received such attention. Considered as a set of socio-technical innovations, virtual worlds are not just about technical possibilities; they also inspired the participants to consider the economic bases for investing in those possibilities and the novel cultural, social, and artistic forms virtual worlds might offer.

The Topical Evolution: Free Ions, Orthomolecular Agents, Phytochemicals, and Insect-Produced Substances  

PubMed Central

Significance: A variety of topical antiseptic substances have been used historically to treat open wounds with suspected tissue infection or that are slow to heal. However, the effectiveness of these substances in treating infected or recalcitrant wounds remains controversial. Recent Advances: Newly formulated topical antiseptics delivered through differing dressing technologies, such as ionic substances, hold the potential to limit the development of and treat antibiotic-resistant microbes in open wounds. Other topically delivered substances, such as insect-derived substances, orthomolecular agents, and phytochemicals, also present opportunities to optimize wound healing by decreasing tissue bioburden and facilitating the wound healing process. Critical Issues: Limited systemic perfusion of open wounds in individuals with certain diagnoses, such as peripheral arterial disease or necrotizing infection and the increasing number of antibiotic-resistant wound pathogens, suggests a continued role for topically applied antiseptic agents. Likewise, the failure of wounds to heal when treated with standard of care therapy opens the door to innovative treatment approaches that include the natural substances described in this article. Future Directions: Evidence for the use of select topical antiseptic agents from each of the aforementioned categories will be discussed in this article. Additional well-controlled clinical studies are needed to provide definitive recommendations for many of these topical agents. PMID:25126473

Delivery of topical antibiotics: pharmacokinetics and clinical problems.  

PubMed

Despite major advances in new therapeutic agents to treat pneumonia, pneumonia remains a major cause of morbidity and mortality in hospitalized patients. Topical antibiotics offer many potential advantages in the treatment and prevention of nosocomial pneumonia. These include a high delivery of the drug to the site of infection and the potential for little systemic absorption and, as a result, reduced side effects. The potential disadvantages include failure of topical therapy to reach all diseased areas of the lung and the emergence of resistant organisms. Failure of many of the previous clinical studies has been ascribed to these potential disadvantages. However, little attention has been paid in previous clinical studies to actual dosage and regional distribution of aerosolized antibiotics in the lung and the pharmacokinetics of the aerosol after deposition. One major exception to this has been the use of aerosolized pentamidine, in which careful attention has been paid to nebulizer design, dosage to the lung, regional distribution, and pharmacokinetics. It should serve as the model for the testing of topical antibiotics therapy in the future. PMID:1754736

Organization's Orderly Interest Exploration: Inception, Development and Insights of AIAA's Topics Database  

NASA Technical Reports Server (NTRS)

Since 2003, AIAA's Computer Systems and Software Systems Technical Committees (TCs) have developed a database that aids technical committee management to map technical topics to their members. This Topics/Interest (T/I) database grew out of a collection of charts and spreadsheets maintained by the TCs. Since its inception, the tool has evolved into a multi-dimensional database whose dimensions include the importance, interest and expertise of TC members and whether or not a member and/or a TC is actively involved with the topic. In 2005, the database was expanded to include the TCs in AIAA s Information Systems Group and then expanded further to include all AIAA TCs. It was field tested at an AIAA Technical Activities Committee (TAC) Workshop in early 2006 through live access by over 80 users. Through the use of the topics database, TC and program committee (PC) members can accomplish relevant tasks such as: to identify topic experts (for Aerospace America articles or external contacts), to determine the interest of its members, to identify overlapping topics between diverse TCs and PCs, to guide new member drives and to reveal emerging topics. This paper will describe the origins, inception, initial development, field test and current version of the tool as well as elucidate the benefits and insights gained by using the database to aid the management of various TC functions. Suggestions will be provided to guide future development of the database for the purpose of providing dynamics and system level benefits to AIAA that currently do not exist in any technical organization.

High Priority Future Research Needs for Obstructive Sleep Apnea Diagnosis and Treatment  

PubMed Central

Study Objectives: To identify and prioritize future research needs (FRN) topics for diagnosis and treatment of obstructive sleep apnea (OSA). Methods: Twenty-one panel members represented six stake-holder categories: patients and the public, providers; purchasers of health care, payers, policymakers, and principal investigators. Building on a recently completed comparative effectiveness review, stakeholders nominated and discussed potential FRN topics. Stakeholders then nominated their top priority FRN topics based on the Agency for Healthcare Research and Quality Effective Health Care Program Selection Criteria. From these nominations, the highest priority FRN topics were determined and were elaborated upon to include possible study designs to address the topics. Results: Thirty-seven topics were discussed and prioritized. The nine highest priority FRN topics included: cost-effectiveness of management strategies, defining age- and sex-specific criteria for OSA, evaluating routine preoperative screening for OSA, evaluating involvement of a sleep medicine specialist in diagnosis of OSA, evaluating clinical prediction rules, assessing the effect of treating sleep disordered breathing and long-term clinical outcomes, comparing treatments for patients who do not tolerate positive airway pressure, evaluating strategies to improve treatment compliance, and evaluating the association between sleep apnea severity and long-term clinical outcomes. Conclusions: While there are numerous specific research questions with low or insufficient strength of evidence for OSA management, OSA patients, their healthcare providers, and society at large would benefit from refocusing research efforts into the prioritized research questions and away from simple comparisons of short-term outcomes between specific interventions.

Haloprogin: a Topical Antifungal Agent  

PubMed Central

Haloprogin was shown to be a highly effective agent for the treatment of experimentally induced topical mycotic infections in guinea pigs. Its in vitro spectrum of activity also includes yeasts, yeastlike fungi (Candida species), and certain gram-positive bacteria. The in vitro and in vivo antifungal activity of haloprogin against dermatophytes was equal to that observed with tolnaftate. The striking differences between the two agents were the marked antimonilial and selective antibacterial activities shown by haloprogin, contrasted with the negligible activities found with tolnaftate. Addition of serum decreased the in vitro antifungal activity of haloprogin to a greater extent than that of tolnaftate; however, diminished antifungal activity was not observed when haloprogin was applied topically to experimental dermatophytic infections. Based on its broad spectrum of antimicrobial activity, haloprogin may prove to be a superior topical agent in the treatment of dermatophytic and monilial infections in man. PMID:5422306

Additional EIPC Study Analysis: Interim Report on High Priority Topics  

SciTech Connect

Between 2010 and 2012 the Eastern Interconnection Planning Collaborative (EIPC) conducted a major long-term resource and transmission study of the Eastern Interconnection (EI). With guidance from a Stakeholder Steering Committee (SSC) that included representatives from the Eastern Interconnection States Planning Council (EISPC) among others, the project was conducted in two phases. Phase 1 involved a long-term capacity expansion analysis that involved creation of eight major futures plus 72 sensitivities. Three scenarios were selected for more extensive transmission- focused evaluation in Phase 2. Five power flow analyses, nine production cost model runs (including six sensitivities), and three capital cost estimations were developed during this second phase. The results from Phase 1 and 2 provided a wealth of data that could be examined further to address energy-related questions. A list of 13 topics was developed for further analysis; this paper discusses the first five.

Future land use plan  

SciTech Connect

The US Department of Energy`s (DOE) changing mission, coupled with the need to apply appropriate cleanup standards for current and future environmental restoration, prompted the need for a process to determine preferred Future Land Uses for DOE-owned sites. DOE began the ``Future Land Use`` initiative in 1994 to ensure that its cleanup efforts reflect the surrounding communities` interests in future land use. This plan presents the results of a study of stakeholder-preferred future land uses for the Brookhaven National Laboratory (BNL), located in central Long Island, New York. The plan gives the Laboratory`s view of its future development over the next 20 years, as well as land uses preferred by the community were BNL ever to cease operations as a national laboratory (the post-BNL scenario). The plan provides an overview of the physical features of the site including its history, topography, geology/hydrogeology, biological inventory, floodplains, wetlands, climate, and atmosphere. Utility systems and current environmental operations are described including waste management, waste water treatment, hazardous waste management, refuse disposal and ground water management. To complement the physical descriptions of the site, demographics are discussed, including overviews of the surrounding areas, laboratory population, and economic and non-economic impacts.

Retapamulin: a newer topical antibiotic.  

PubMed

Impetigo is a common childhood skin infection. There are reports of increasing drug resistance to the currently used topical antibiotics including fusidic acid and mupirocin. Retapamulin is a newer topical agent of pleuromutilin class approved by the Food and Drug Administration for treatment of impetigo in children and has been recently made available in the Indian market. It has been demonstrated to have low potential for the development of antibacterial resistance and a high degree of potency against poly drug resistant Gram-positive bacteria found in skin infections including Staphylococcus aureus strains. The drug is safe owing to low systemic absorption and has only minimal side-effect of local irritation at the site of application. PMID:23793314

Tribological Limitations in Gas Turbine Engines: A Workshop to Identify the Challenges and Set Future Directions  

NASA Technical Reports Server (NTRS)

The following report represents a compendium of selected speaker presentation materials and observations made by Prof O. Pinkus at the NASA/ASME/Industry sponsored workshop entitled "Tribological Limitations in Gas Turbine Engines" held on September 15-17, 1999 in Albany, New York. The impetus for the workshop came from the ASME's Research Committee on Tribology whose goal is to explore new tribological research topics which may become future research opportunities. Since this subject is of current interest to other industrial and government entities the conference received cosponsorship as noted above. The conference was well attended by government, industrial and academic participants. Topics discussed included current tribological issues in gas turbines as well as the potential impact (drawbacks and advantages) of future tribological technologies especially foil air bearings and magnetic beatings. It is hoped that this workshop report may serve as a starting point for continued discussions and activities in oil-free turbomachinery systems.

[Topical therapy of rosacea].  

PubMed

Metronidazole and azelaic acid are the only topical medications approved for rosacea. All other topical treatments for rosacea and its special forms are used off-label. Topical steroids are not indicated in rosacea, because of their side effects (induction of steroid rosacea, high risk of facial skin atrophy, and high risk of rebound after cessation of therapy). Topical as well as systemic steroids are allowed only as initial and short term therapy for acute forms of rosacea (e.g. rosacea fulminans). Papular and pustular rosacea is the major indication for topical therapy. Sebaceous gland and connective tissue hyperplasia in glandular-hypertrophic rosacea as well as erythema in erythematous rosacea do not respond well to topical measures. A new active substance, the alpha-2-adrenoreceptor agonist brimonidine, will be approved soon for the topical treatment of erythema in rosacea. All severe forms of rosacea should initially be treated with a combination of topical and systemic agents. After improvement of the clinical symptoms, topical treatment alone is usually adequate to maintain the control. PMID:23780475

Topical Resiquimod Protects against Visceral Infection with Leishmania infantum chagasi in Mice  

PubMed Central

New prevention and treatment strategies are needed for visceral leishmaniasis, particularly ones that can be deployed simply and inexpensively in areas where leishmaniasis is endemic. Synthetic molecules that activate Toll-like receptor 7 and 8 (TLR7/8) pathways have previously been demonstrated to enhance protection against cutaneous leishmaniasis. We initially sought to determine whether the TLR7/8-activating molecule resiquimod might serve as an effective vaccine adjuvant targeting visceral leishmaniasis caused by infection with Leishmania infantum chagasi. Resiquimod was topically applied to the skin of mice either prior to or after systemic infection with L. infantum chagasi, and parasite burdens were assessed. Surprisingly, topical resiquimod application alone, in the absence of vaccination, conferred robust resistance to mice against future intravenous challenge with virulent L. infantum chagasi. This protection against L. infantum chagasi infection persisted as long as 8 weeks after the final topical resiquimod treatment. In addition, in mice with existing infections, therapeutic treatment with topical resiquimod led to significantly lower visceral parasite loads. Resiquimod increased trafficking of leukocytes, including B cells, CD4+ and CD8+ T cells, dendritic cells, macrophages, and granulocytes, in livers and spleens, which are the key target organs of visceralizing infection. We conclude that topical resiquimod leads to systemic immune modulation and confers durable protection against visceralizing L. infantum chagasi infection, in both prophylactic and therapeutic settings. These studies support continued studies of TLR-modulating agents to determine mechanisms of protection and also provide a rationale for translational development of a critically needed, novel class of topical, preventative, and therapeutic agents for these lethal infections.

Hot topics in noise  

NASA Astrophysics Data System (ADS)

Our world continues to be a noisy place and the challenge to ``increase and diffuse knowledge of noise propagation, passive and active noise control, and the effects of noise'' remains. In the last several years, noise in the classroom has emerged as one of the hotter topics: Considerable progress has been made in the underpinning research, the formulation of recommendations, and the process of educating society on the social and personal impact of inadequate acoustical conditions in classrooms. The establishment of the ANSI S12.60-2002 standard for classroom acoustics was a milestone event. Noise in cities and the understanding of our soundscapes are subjects of ongoing significance. The development of standards and regulations is a continuing process, with urban community noise regulations, aviation noise, and the preservation of natural quiet in national parks being of current concern. New methods to reduce noise are under development and include passive and active methods of noise control, techniques for modeling the performance of noise barriers, and approaches for designing product sound quality.

Epilepsy care: image of the future.  

PubMed

A number of factors have contributed to improvements in the care of epilepsy during the past decade, including the International League Against Epilepsy classifications, therapeutic antiepileptic drug (AED) monitoring and the concept of monotherapy, new AEDs with novel mechanisms of action, and new insights into etiology that suggest novel therapies. Pharmacologically "clean" AEDs acting on a single known mechanism will be an important element in the future care of patients with epilepsy. Augmentation of GABAergic inhibition is being successfully exploited by AEDs, and there remains much room for further pharmacologic innovation. The potential role of AEDs acting specifically on the GAT-1 or GAT-4 subgroup of gamma-aminobutyric acid transporters is a topic of current research. Specifically acting AEDs designed to have a single and known mode of action will permit true monotherapy, one AED with one target as opposed to one AED with several targets, and may open the way to rational polytherapy, i.e., designed use of one AED per mechanism in epilepsies with multifactorial causation. New research demonstrating a possible autoimmune basis for some forms of epilepsy illustrates the potential for novel nonpharmacologic approaches, and the role of prevention must also be emphasized. The image of the future is an optimistic one. PMID:8595790

Topical anaesthetics, often used by anaesthetists, dentists and dermatologists, have increasingly been recognised for their utility in paediatrics. With topical anaesthetics, the 'ouchless' paediatric practice becomes an achievable goal. The primary drawback to their use is the length of time for anaesthetic effect, but planning ahead and making use of newer formulations and adjuncts can overcome this barrier. This update will review topical anaesthetic formulations available, adjuncts to reduce the time to anaesthesia, adverse effects, common indications and products on the horizon. PMID:24990195

Climate Change Impacts on Forest Succession and Future Productivity  

NASA Astrophysics Data System (ADS)

Change in ecosystem carbon (C) dynamics with forest succession is a long-studied topic in ecology, and secondary forests currently comprise a significant proportion of the global land base. Although mature forests are generally more important for conserving species and habitats, early successional trees and stands typically have higher rates of productivity, including net ecosystem productivity (NEP), which represents carbon available for sequestration. Secondary forests undergoing successional development are thus major players in the current global carbon cycle, yet how forests will function in the future under warmer conditions with higher atmospheric carbon dioxide (CO2) concentrations is unknown. Future forest C dynamics will depend, in part, on future species composition. Data from "Forests of the Future" research in a number of global change experiments provide insights into how forests may look in terms of dominant species composition, and thus function, in a future world. Studies at Free-Air Carbon Dioxide (FACE) experiments at Duke Forest and other facilities, plus climate warming experiments such as those at the Harvard Forest, suggest a common underlying principle of vegetation responses to environmental manipulation: Namely, that shade-tolerant woody species associating with arbuscular mycorrhizal (AM) fungi show greater growth stimulation than ectomycorrhizal-associating (ECM) trees which are more common in temperate and boreal forests (Fig. 1 of relative growth rates standardized by pre-treatment rates). This may be due in part to the role of AM fungi in obtaining soil phosphorus and inorganic forms of nitrogen for plant associates. In combination, these results suggest a shift in future forest composition towards less-productive tree species that generally acquire atmospheric CO2 at lower annual rates, as well as a competitive advantage extended to woody vines such as poison ivy. Due to higher atmospheric CO2 and warmer temperatures, forests of the future may become less-productive than those of today.

The future of human spaceflight  

NASA Astrophysics Data System (ADS)

After the Apollo Moon program, the international space station represents a further milestone of humankind in space. International follow-on programs like a manned return to the Moon and a first manned Mars Mission can be considered as the next logical step. More and more attention is also paid to the topic of future space tourism in Earth orbit, which is currently under investigation in the USA, Japan and Europe due to its multibillion dollar market potential and high acceptance in society. The wide variety of experience, gained within the space station program, should be used in order to achieve time and cost savings for future manned programs. Different strategies and roadmaps are investigated for space tourism and human missions to the Moon and Mars, based on a comprehensive systems analysis approach. By using DLR's software tool FAST ( Fast Assessment of Space Technologies), different scenarios will be defined, optimised and finally evaluated with respect to mission architecture, required technologies, total costs and program duration. This includes trajectory analysis, spacecraft design on subsystem level, operations and life cycle cost analysis. For space tourism, an expected evolutionary roadmap will be described which is initiated by short suborbital tourism and ends with visionary designs like the Space Hotel Berlin and the Space Hotel Europe concept. Furthermore the potential space tourism market, its economic meaning as well as the expected range of the costs of a space ticket (e.g. 50,000 for a suborbital flight) will be analysed and quantified. For human missions to the Moon and Mars, an international 20 year program for the first decades of the next millennium is proposed, which requires about 2.5 Billion per year for a manned return to the Moon program and about $2.6 Billion per year for the first 3 manned Mars missions. This is about the annual budget, which is currently spend by the USA only for the operations of its Space Shuttle fleet which generally proofs the affordability of such ambitious programs after the build-up of the International Space Station, when corresponding budget might become again available.

Tribological Limitations in Gas Turbine Engines: A Workshop to Identify the Challenges and Set Future Directions. Revised  

NASA Technical Reports Server (NTRS)

The following report represents a compendium of selected speaker presentation materials and observations made by Prof. O. Pinkus at the NASA/ASME/Industry sponsored workshop entitled "Tribological Limitations in Gas Turbine Engines" held on September 15-17, 1999 in Albany, New York. The impetus for the workshop came from the ASME's Research Committee on tribology whose goal is to explore new tribological research topics which may become future research opportunities. Since this subject is of current interest to other industrial and government entities the conference received cosponsorship as noted above. The conference was well attended by government, industrial, and academic participants. Topics discussed included current tribological issues in gas turbines as well as the potential impact (drawbacks and advantages) of future tribological technologies especially foil air bearings and magnetic bearings. It is hoped that this workshop report may serve as a starting point for continued discussions and activities in oil-free turbomachinery systems.

Ganciclovir ophthalmic gel 0.15% for the treatment of acute herpetic keratitis: background, effectiveness, tolerability, safety, and future applications  

PubMed Central

Eye disease due to herpes simplex virus (HSV) is a leading cause of ocular morbidity and the number one infectious cause of unilateral corneal blindness in the developed parts of the globe. Recurrent keratitis can result in progressive corneal scarring, thinning, and vascularization. Antiviral agents employed against HSV have primarily been nucleoside analogs. Early generation drugs included idoxuridine, iododesoxycytidine, vidarabine, and trifluridine. While effective, they tended to have low bioavailability and measurable local cellular toxicity due to their nonselective mode of action. Acyclovir 0.3% ointment is a more selective agent, and had become a first-line topical drug for acute HSV keratitis in Europe and other places outside of the US. Ganciclovir 0.15% gel is the most recently approved topical treatment for herpes keratitis. Compared to acyclovir 0.3% ointment, ganciclovir 0.15% gel has been shown to be better tolerated and no less effective in several Phase II and III trials. Additionally, topical ganciclovir does not cause adverse systemic side effects and is therapeutic at lower concentrations. Based on safety, efficacy, and tolerability, ganciclovir 0.15% gel should now be considered a front-line topical drug in the treatment of dendritic herpes simplex epithelial keratitis. Topics of future investigation regarding other potential uses for ganciclovir gel may include the prophylaxis of recurrent HSV epithelial keratitis, treatment of other forms of ocular disease caused by herpesviruses and adenovirus, and ganciclovir gel as an adjunct to antitumor therapy.

Using NASA Space Imaging Technology to Teach Earth and Sun Topics  

NASA Astrophysics Data System (ADS)

We teach an experimental college-level course, directed toward elementary education majors, emphasizing "hands-on" activities that can be easily applied to the elementary classroom. This course, Physics 240: "The Sun-Earth Connection" includes various ways to study selected topics in physics, earth science, and basic astronomy. Our lesson plans and EPO materials make extensive use of NASA imagery and cover topics about magnetism, the solar photospheric, chromospheric, coronal spectra, as well as earth science and climate. In addition we are developing and will cover topics on ecosystem structure, biomass and water on Earth. We strive to free the non-science undergraduate from the "fear of science" and replace it with the excitement of science such that these future teachers will carry this excitement to their future students. Hands-on experiments, computer simulations, analysis of real NASA data, and vigorous seminar discussions are blended in an inquiry-driven curriculum to instill confident understanding of basic physical science and modern, effective methods for teaching it. The course also demonstrates ways how scientific thinking and hands-on activities could be implemented in the classroom. We have designed this course to provide the non-science student a confident basic understanding of physical science and modern, effective methods for teaching it. Most of topics were selected using National Science Standards and National Mathematics Standards that are addressed in grades K-8. The course focuses on helping education majors: 1) Build knowledge of scientific concepts and processes; 2) Understand the measurable attributes of objects and the units and methods of measurements; 3) Conduct data analysis (collecting, organizing, presenting scientific data, and to predict the result); 4) Use hands-on approaches to teach science; 5) Be familiar with Internet science teaching resources. Here we share our experiences and challenges we face while teaching this course.

Phototriggerable Liposomes: Current Research and Future Perspectives  

PubMed Central

The field of cancer nanomedicine is considered a promising area for improved delivery of bioactive molecules including drugs, pharmaceutical agents and nucleic acids. Among these, drug delivery technology has made discernible progress in recent years and the areas that warrant further focus and consideration towards technological developments have also been recognized. Development of viable methods for on-demand spatial and temporal release of entrapped drugs from the nanocarriers is an arena that is likely to enhance the clinical suitability of drug-loaded nanocarriers. One such approach, which utilizes light as the external stimulus to disrupt and/or destabilize drug-loaded nanoparticles, will be the discussion platform of this article. Although several phototriggerable nanocarriers are currently under development, I will limit this review to the phototriggerable liposomes that have demonstrated promise in the cell culture systems at least (but not the last). The topics covered in this review include (i) a brief summary of various phototriggerable nanocarriers; (ii) an overview of the application of liposomes to deliver payload of photosensitizers and associated technologies; (iii) the design considerations of photoactivable lipid molecules and the chemical considerations and mechanisms of phototriggering of liposomal lipids; (iv) limitations and future directions for in vivo, clinically viable triggered drug delivery approaches and potential novel photoactivation strategies will be discussed.

Mapping topics and topic bursts in PNAS.  

PubMed

Scientific research is highly dynamic. New areas of science continually evolve; others gain or lose importance, merge, or split. Due to the steady increase in the number of scientific publications, it is hard to keep an overview of the structure and dynamic development of one's own field of science, much less all scientific domains. However, knowledge of "hot" topics, emergent research frontiers, or change of focus in certain areas is a critical component of resource allocation decisions in research laboratories, governmental institutions, and corporations. This paper demonstrates the utilization of Kleinberg's burst detection algorithm, co-word occurrence analysis, and graph layout techniques to generate maps that support the identification of major research topics and trends. The approach was applied to analyze and map the complete set of papers published in PNAS in the years 1982-2001. Six domain experts examined and commented on the resulting maps in an attempt to reconstruct the evolution of major research areas covered by PNAS. PMID:14978278

Future advances.  

PubMed

Future advances in the auditory systems are difficult to predict, and only educated guesses are possible. It is expected that innovative technologies in the field of neuroscience will be applied to the auditory system. Optogenetics, Brainbow, and CLARITY will improve our knowledge of the working of neural auditory networks and the relationship between sound and language, providing a dynamic picture of the brain in action. CLARITY makes brain tissue transparent and offers a three-dimensional view of neural networks, which, combined with genetically labeling neurons with multiple, distinct colors (Optogenetics), will provide detailed information of the complex brain system. Molecular functional magnetic resonance imaging (MRI) will allow the study of neurotransmitters detectable by MRI and their function in the auditory pathways. The Human Connectome project will study the patterns of distributed brain activity that underlie virtually all aspects of cognition and behavior and determine if abnormalities in the distributed patterns of activity may result in hearing and behavior disorders. Similarly, the programs of Big Brain and ENIGMA will improve our understanding of auditory disorders. New stem-cell therapy and gene therapies therapy may bring about a partial restoration of hearing for impaired patients by inducing regeneration of cochlear hair cells. PMID:25726297

The future: genes, physical activity and health.  

PubMed

The assigned title for the Lindhard presentation was to examine the future of genes, physical activity and health. The current review is a summary of this presentation. Caution is expressed that technology is improving so rapidly that a future view is limited to a few years as opposed to the 100 years passing since Lindhard's achievements. The near futuristic opportunities and challenges for four major topic topics are reviewed here. Concerns are expressed over current usage of the terms 'control' group and 'non-responders' in exercise research. Our view is that 'control' needs to be differentiated between its usage for treatments of exercise to restore natural functions in individuals with less than healthy levels of physical activity and the inherited genome's expectation for physical activity levels to maintain normal function. For the second discussed topic, it is proposed that the term 'non-responders' should be replaced by the term 'low sensitivity' as there may be no such human who is a non-responder to every exercise adaptation. The third futuristic topic is exercise prescription as envisioned for individualized medicine. However, numerous limitations and challenges exist to truly optimal exercise medicine at the level of one individual. Finally, preventative physical activity medicine is discussed. Physical activity as a therapy now exists to prevent most of the chronic diseases. The future needs to understand the molecular basis for how the body becomes dysfunctional when its level of physical activity does not match the norm of physical activity that selected our inherited genome.

Seborrheic dermatitis is a multifactorial skin disease characterized by a chronic course with periods of exacerbation and remission. Although topical corticosteroids have been the mainstay of treatment, alternative therapies are often needed to avoid protracted use of topical corticosteroid therapy in order to avert side effects and to sustain control of the disorder. Topical pimecrolimus, a calcinuerin inhibitor, is a safe alternative for seborrheic dermatitis and is more ideal for long-term use. More specifically, topical pimecrolimus not only has an attractive safety profile with no risk of many of the potential side effects seen with topical corticosteroids, but also has favorable efficacy data, including more data on long-term use. This is a review of literature evaluating the efficacy and safety profile of topical pimecrolimus 1% cream for the treatment of seborrheic dermatitis. PMID:23441238

Future Climate Analysis  

SciTech Connect

This report documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain, Nevada, the site of a repository for spent nuclear fuel and high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this report provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the following reports: ''Simulation of Net Infiltration for Present-Day and Potential Future Climates'' (BSC 2004 [DIRS 170007]), ''Total System Performance Assessment (TSPA) Model/Analysis for the License Application'' (BSC 2004 [DIRS 168504]), ''Features, Events, and Processes in UZ Flow and Transport'' (BSC 2004 [DIRS 170012]), and ''Features, Events, and Processes in SZ Flow and Transport'' (BSC 2004 [DIRS 170013]). Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one available forecasting method for establishing upper and lower bounds for future climate estimates. The selection of different methods is directly dependent on the available evidence used to build a forecasting argument. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. While alternative analyses are possible for the case presented for Yucca Mountain, the evidence (data) used would be the same and the conclusions would not be expected to drastically change. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog. Other alternative approaches could include simulation of climate over the 10,000-year period; however, this modeling extrapolation is well beyond the bounds of current scientific practice and would not provide results with better confidence. A corroborative alternative approach may be found in ''Future Climate Analysis-10,000 Years to 1,000,000 Years After Present'' (Sharpe 2003 [DIRS 161591]). The current revision of this report is prepared in accordance with ''Technical Work Plan for: Unsaturated Zone Flow Analysis and Model Report Integration'' (BSC 2004 [DIRS 169654]).

Through a Glass Darkly: Glimpses into the Future of Mass Spectrometry  

PubMed Central

The paper has three parts, (i) a brief overview of the main achievements made using mass spectrometry across all the fields of science, (ii) a survey of some of the topics currently being pursued most activity, including both applications and fundamental studies, and (iii) some hints as to what the future of mass spectrometry might hold with particular emphasis on revolutionary changes in the subject. Emphasis is given to ambient methods of ionization and their use in disease diagnosis and to their use in combination with miniature mass spectrometers for in-situ measurements. Special attention goes to the chemical aspects of mass spectrometry, including its emerging role as a preparative method based on accelerated bimolecular reaction rates in solution and on ion soft landing as a means of surface tailoring. In summary, the paper covers the proud history, vibrant present and expansive future of mass spectrometry. PMID:24349920

PREFACE: CEWQO Topical Issue CEWQO Topical Issue  

NASA Astrophysics Data System (ADS)

This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and Sascha Wallentowitz), 2004 (Trieste, Italy, by Naseem Rahman and Sascha Wallentowitz), 2005 (Bilkent, Ankara, by Alexander Shumovsky), 2006 (Vienna, by Helmut Rauch), 2007 (Palermo, Italy, by Antonino Messina) and 2008 (Belgrade, by Mirjana Bozic). The CEWQO series developed in two directions following the rapid development of quantum optics and the transitional development of the scientific collaboration of Central European researchers with researchers from old and new emerging Central European countries, and from all over the world. The topics discussed at CEWQO 08 were divided into ten groups that aimed to cover the broad scope of modern quantum optics: Fundamental aspects of quantum optics and quantum mechanics Single photons and photon pairs Cavity and circuit QED Atoms in intense fields Neutron, atom and molecular quantum optics Quantum gases and fluids Coherence, entanglement and decoherence Optical properties of condensed matter and nanostructures Open quantum systems and chaos Quantum information processing Central European Workshops on Quantum Optics realize and are consistent with a wider idea, and a social, economical, cultural and political program promoted since 1989 by the Central European Initiative (CEI), the main goal of which was to help transition countries in Central Europe to become closer to the EU. The resulting support of the CEI, first obtained thanks to the scientific reputation, organizing activities, and efforts of Helmut Rauch, has been very important for the organization of the CEWQO in recent years, particularly in 2008. The support of the Sixth and Seventh Framework Programs of the European Commission was also very important. A short review of papers in this topical issue A principal role in this topical issue is played by the photon. Vuletic et al describe the mapping of the photon-polarization state onto a single collective-spin excitation (magnon) shared between two atomic ensembles. A heralded quantum memory based on this mapping is demonstrated. Dodonov derives a formula which predicts a photon generation rate in a cavity due to

A View on Future Building System Modeling and Simulation  

SciTech Connect

This chapter presents what a future environment for building system modeling and simulation may look like. As buildings continue to require increased performance and better comfort, their energy and control systems are becoming more integrated and complex. We therefore focus in this chapter on the modeling, simulation and analysis of building energy and control systems. Such systems can be classified as heterogeneous systems because they involve multiple domains, such as thermodynamics, fluid dynamics, heat and mass transfer, electrical systems, control systems and communication systems. Also, they typically involve multiple temporal and spatial scales, and their evolution can be described by coupled differential equations, discrete equations and events. Modeling and simulating such systems requires a higher level of abstraction and modularisation to manage the increased complexity compared to what is used in today's building simulation programs. Therefore, the trend towards more integrated building systems is likely to be a driving force for changing the status quo of today's building simulation programs. Thischapter discusses evolving modeling requirements and outlines a path toward a future environment for modeling and simulation of heterogeneous building systems.A range of topics that would require many additional pages of discussion has been omitted. Examples include computational fluid dynamics for air and particle flow in and around buildings, people movement, daylight simulation, uncertainty propagation and optimisation methods for building design and controls. For different discussions and perspectives on the future of building modeling and simulation, we refer to Sahlin (2000), Augenbroe (2001) and Malkawi and Augenbroe (2004).

Topics In Primitive Roots  

E-print Network

This monograph considers a few topics in the theory of primitive roots g(p) modulo a prime p>=2. A few estimates of the least primitive roots g(p) and the least prime primitive roots g^*(p) modulo p, a large prime, are determined. One of the estimate here seems to sharpen the Burgess estimate g(p) number 3 > 0, to the smaller estimate g(p) 2. The expected order of magnitude is g(p) 1 constant. The corresponding estimates for least prime primitive roots g^*(p) are slightly higher. Anotrher topic deals with an effective lower bound #{p > x/log x for the number of primes p number x >1. The current results in the literature claim the lower bound #{p > x/(log x)^2, and have restrictions on the minimal number of fixed integers to three or more.

Dave Young's Chemical Topics  

NSDL National Science Digital Library

This collection of articles from Dave Young of Cytoclonal Pharmaceutics covers select topics in computational chemistry (e.g., molecular vibrations, pharmaceuticals, spin contamination), magnetochemistry, states of matter, and Gaussian, Mopac, and Unix computer languages. The articles are plucked from Young's publication Computational Chemistry: A Practical Guide for Applying Techniques to Real World Problems, scheduled to be published by John Wiley & Sons this spring. the articles are intended to be introductory and don't go into topics in depth, but some of the discussions are actually fairly advanced. The introductory section features a nice discussion of the terms "theoretical" and "computational" chemistry, with a warning of the pitfalls of relying too much on strictly computational methods. This is an interesting, informative resource for teachers of college-level chemistry.

EDITORIAL: The present and future  

NASA Astrophysics Data System (ADS)

Neural engineering has grown substantially in the last few years and it is time to review the progress of the first journal in this field. Journal of Neural Engineering (JNE) is a quarterly publication that started in 2004. The journal is now in its third volume and eleven issues, consisting of 114 articles in total, have been published since its launch. The editorial processing times have been kept to a minimum, the receipt to first decision time is 41 days, on average, and the time from receipt to publication has been maintained below three months. It is also worth noting that it is free to publish in Journal of Neural Engineering—there are no author fees—and once published the articles are free online for the first month. The journal has been listed in Pubmed® since 2005 and has been accepted by ISI® in 2006. Who is reading Journal of Neural Engineering? The number of readers of JNE has increased significantly from 8050 full-text downloads in 2004 to 14 900 in 2005 and the first seven months of 2006 have already seen 12 800 downloads. The top users in 2005 were the Microsoft Corporation, Stanford University and the University of Michigan. The list of top ten users also includes non-US institutions: University of Toronto, University of Tokyo, Hong Kong Polytechnic, National Library of China and University College London, reflecting the international flavor of the journal. What are the hot topics in neural engineering? Based on the number of downloads and citations for 2004-2005, the top three topics are: (1) Brain-computer interfaces (2) Visual prostheses (3) Neural modelling Several other topics such as microelectrode arrays, neural signal processing, neural dynamics and neural circuit engineering are also in the top ten. Where are Journal of Neural Engineering articles cited? JNE articles have reached a wide audience and have been cited in of some of the best journals in physiology and neuroscience such as Nature Neuroscience, Journal of Neuroscience, Trends in Neuroscience, Journal of Physiology, Proceedings of the National Academy of Science as well as in engineering and physics journals such as Annals of Biomedical Engineering, Physical Review Letters and IEEE Transactions on Biomedical Engineering. However, the number of citations in clinical journals is limited. What is special about Journal of Neural Engineering? JNE has published two special issues: (1) The Eye and the Chip (visual prostheses) (vol. 2, (1), 2005) and (2) Sensory Integration: Role of Internal Models (vol. 2, (3), 2005). These special issues have attracted a lot of attention based on the number of article downloads. JNE also publishes tutorials intended to provide background information on specific topics such as classification, sensory substitution and cortical neural prosthetics. A series of tutorials from the 3rd Neuro-IT and Neuroengineering Summer School has been published with the first appearing in vol. 2 (4), 2005. What is in the future for Journal of Neural Engineering? The goal of any journal should be to provide a particular field with the best venue for scientists and engineers to make their work available and noticeable to the rest of the community. In particular, attracting a strong readership base and high quality manuscripts should be the first priority. Providing accurate, reliable and speedy reviews should be the next. With an international board of experts in the field of neural engineering, a solid base of reviewers, readers and contributors, JNE is in a strong position to continue to serve the neural engineering community. However, this is still a small community and growth is essential for continued success in this area. There are two areas of expansion of great interest for the field of neural engineering currently poised between basic science on one hand and clinical implementation on the other: translational neuroscience and therapeutic neural engineering. We should strive to bridge the gap between basic neuroscience, clinical science and engineering by attracting contributions from neuroscientists and clinicians w

Teaching Climate Change to Future Teachers Using 'Real' Data: Challenges and Opportunities (Invited)  

NASA Astrophysics Data System (ADS)

A climate-literate public is essential to resolving pressing problems related to global change. Future elementary teachers are a critical audience in climate and climate change education, as they will introduce children in early grades (USA grades K-8, children ages 5-14) to fundamentals of the climate system, natural and anthropogenic drivers of climate change, and impacts of global change on human and natural systems. Here we describe challenges we have encountered in teaching topics of the carbon cycle, greenhouse gases, past climate, recent anthropogenic change, and carbon footprints to future elementary teachers. We also describe how we have met (to varying degrees of success) these challenges in an introductory earth science course that is specifically designed for this audience. Two prominent challenges we have encountered are: the complex nature of the scientific content of climate change, and robust misconceptions held by our students about these topics. To address the first challenge, we attempt to adjust the scientific content to a level appropriate for future K-8 teachers, without sacrificing too much accuracy or critical detail. To address the second challenge, we explicitly discuss alternate conceptions of each topic. The use of authentic data sets can also address both of these challenges. Yet incorporating 'real' climate and paleoclimate data into the classroom poses still an additional challenge of instructional design. We use a variety of teaching approaches in our laboratory-based course including student-designed experiments, computer simulations, physical models, and authentic data sets. We have found that students strongly prefer the physical models and experiments, because these are 'hands-on' and perceived as easily adaptable to the K-8 classroom. Students often express dislike for activities that use authentic data sets (for example, an activity using graphs of CO2 and methane concentrations in Vostok ice cores), in particular because they have difficulty interpreting graphs. To respond to this concern, we couple physical models/experiments with data sets in a guided inquiry teaching format in order to satisfy those students who prefer 'hands-on' learning yet tie the models to the real world. Pre/post testing of students shows that this method is effective in most topics, yet future teachers still struggle with identifying natural versus anthropogenic drivers of climate change. We continue to address these challenges in future course modifications.

TOPICAL REVIEW: Advances and challenges in computational plasma science  

NASA Astrophysics Data System (ADS)

Scientific simulation, which provides a natural bridge between theory and experiment, is an essential tool for understanding complex plasma behaviour. Recent advances in simulations of magnetically confined plasmas are reviewed in this paper, with illustrative examples, chosen from associated research areas such as microturbulence, magnetohydrodynamics and other topics. Progress has been stimulated, in particular, by the exponential growth of computer speed along with significant improvements in computer technology. The advances in both particle and fluid simulations of fine-scale turbulence and large-scale dynamics have produced increasingly good agreement between experimental observations and computational modelling. This was enabled by two key factors: (a) innovative advances in analytic and computational methods for developing reduced descriptions of physics phenomena spanning widely disparate temporal and spatial scales and (b) access to powerful new computational resources. Excellent progress has been made in developing codes for which computer run-time and problem-size scale well with the number of processors on massively parallel processors (MPPs). Examples include the effective usage of the full power of multi-teraflop (multi-trillion floating point computations per second) MPPs to produce three-dimensional, general geometry, nonlinear particle simulations that have accelerated advances in understanding the nature of turbulence self-regulation by zonal flows. These calculations, which typically utilized billions of particles for thousands of time-steps, would not have been possible without access to powerful present generation MPP computers and the associated diagnostic and visualization capabilities. In looking towards the future, the current results from advanced simulations provide great encouragement for being able to include increasingly realistic dynamics to enable deeper physics insights into plasmas in both natural and laboratory environments. This should produce the scientific excitement which will help to (a) stimulate enhanced cross-cutting collaborations with other fields and (b) attract the bright young talent needed for the future health of the field of plasma science.

Discovering Health Topics in Social Media Using Topic Models  

PubMed Central

By aggregating self-reported health statuses across millions of users, we seek to characterize the variety of health information discussed in Twitter. We describe a topic modeling framework for discovering health topics in Twitter, a social media website. This is an exploratory approach with the goal of understanding what health topics are commonly discussed in social media. This paper describes in detail a statistical topic model created for this purpose, the Ailment Topic Aspect Model (ATAM), as well as our system for filtering general Twitter data based on health keywords and supervised classification. We show how ATAM and other topic models can automatically infer health topics in 144 million Twitter messages from 2011 to 2013. ATAM discovered 13 coherent clusters of Twitter messages, some of which correlate with seasonal influenza (r?=?0.689) and allergies (r?=?0.810) temporal surveillance data, as well as exercise (r?=?.534) and obesity (r?=??.631) related geographic survey data in the United States. These results demonstrate that it is possible to automatically discover topics that attain statistically significant correlations with ground truth data, despite using minimal human supervision and no historical data to train the model, in contrast to prior work. Additionally, these results demonstrate that a single general-purpose model can identify many different health topics in social media. PMID:25084530

Topic in Depth - Aerodynamics  

NSDL National Science Digital Library

Aerodynamics is the study of what makes things go fast, right? More specifically, itâ??s the study of the interaction between bodies and the atmosphere. This topic in depth highlights some fun websites on the science of aerodynamics, for beginners to researchers. If youâ??ve been watching Wimbeldon lately, you might have been wondering about the aerodynamics of tennis. Or maybe you were riding your bike the other day and wondering how you could pick up a little more speed next time. These sites can help explain.

Creating the Future  

NSDL National Science Digital Library

This activity lets students create and write scenarios for the future related to hazardous waste pollution and its cleanup in the United States. Students describe their scenarios using one of a variety of formats; for example, a newspaper opinion/editorial article, a short story, a play, or a poem. Students will illustrate the facts that many familiar products contain hazardous substances; that hazardous substance is a broad term that includes many chemicals and materials, including poisonous or toxic chemicals; that improper use and disposal of these products can result in the production of hazardous waste that can pollute our environment; and that becoming more aware of the hazardous substances we encounter every day and of the types of hazardous waste they produce, is the first step in learning how to properly handle and dispose of them, thereby protecting ourselves and our environment.

Topics in complex nonlinear systems  

NASA Astrophysics Data System (ADS)

In the dissertation, I include two topics of my research in nonlinear dynamic systems. In the first topic, we use numerical optimization techniques to investigate the behavior of the success rates for two- and three-qubit entangling gates, first for perfect fidelity, and then extended to imperfect gates. We find that as the perfect fidelity condition is relaxed, the maximum attainable success rates increase in a predictable fashion depending on the size of the system, and we compare that rate of increase for several gates. Finally, we propose an experiment to test our imperfect LOQC gates using number-resolving photon detectors. We suggest a relatively simple physical apparatus capable of producing CZ gates with controllable fidelity less than 1 and success rates higher than the current theoretical maximum (S=2/27) for perfect fidelity. These experimental setups are within the reach of many experimental groups and would provide an interesting experiment in photonic quantum computing. In the second topic, we quantitatively study nonlinear effects on the evolution of surface gravity waves on the ocean, to explore systematically the effects of various input parameters on the probability of rogue wave formation. The fourth-order current-modified nonlinear Schrodinger equation (CNLS4) is employed to describe the wave evolution. First, we show that when the average wave steepness is small and nonlinear wave effects are subleading, the wave height distribution is well explained by a single "freak index" parameter, which describes the strength of (linear) wave scattering by random currents relative to the angular spread of the incoming random sea. When the average steepness is large, the wave height distribution takes a very similar functional form, but the key variables determining the probability distribution are the steepness, and the angular and frequency spread of the incoming waves. Then, we obtain quantitative predictions for the wave height distribution as a function of those key environmental conditions. Additionally, we explore the spatial dependence of the wave height distribution, associated with the buildup of nonlinear development. Finally, even greater probability of extreme wave formation is predicted when linear and nonlinear effects are acting together.

Topical Nonsteroidal Anti-Inflammatory Drugs for Macular Edema  

PubMed Central

Nonsteroidal anti-inflammatory drugs (NSAIDs) are nowadays widely used in ophthalmology to reduce eye inflammation, pain, and cystoid macular edema associated with cataract surgery. Recently, new topical NSAIDs have been approved for topical ophthalmic use, allowing for greater drug penetration into the vitreous. Hence, new therapeutic effects can be achieved, such as reduction of exudation secondary to age-related macular degeneration or diabetic maculopathy. We provide an updated review on the clinical use of NSAIDs for retinal diseases, with a focus on the potential future applications. PMID:24227908

Topicality and Impact in Social Media: Diverse Messages, Focused Messengers  

PubMed Central

We have a limited understanding of the factors that make people influential and topics popular in social media. Are users who comment on a variety of matters more likely to achieve high influence than those who stay focused? Do general subjects tend to be more popular than specific ones? Questions like these demand a way to detect the topics hidden behind messages associated with an individual or a keyword, and a gauge of similarity among these topics. Here we develop such an approach to identify clusters of similar hashtags in Twitter by detecting communities in the hashtag co-occurrence network. Then the topical diversity of a user’s interests is quantified by the entropy of her hashtags across different topic clusters. A similar measure is applied to hashtags, based on co-occurring tags. We find that high topical diversity of early adopters or co-occurring tags implies high future popularity of hashtags. In contrast, low diversity helps an individual accumulate social influence. In short, diverse messages and focused messengers are more likely to gain impact. PMID:25710685

Topical NSAIDs for acute pain in adults  

PubMed Central

Background Use of topical NSAIDs to treat acute musculoskeletal conditions is widely accepted in some parts of the world, but not in others. Their main attraction is their potential to provide pain relief without associated systemic adverse events. Objectives To review the evidence from randomised, double-blind, controlled trials on the efficacy and safety of topically applied NSAIDs in acute pain. Search methods We searched MEDLINE, EMBASE, The Cochrane Library, and our own in-house database to December 2009. We sought unpublished studies by asking personal contacts and searching on-line clinical trial registers and manufacturers web sites. Selection criteria We included randomised, double-blind, active or placebo (inert carrier)-controlled trials in which treatments were administered to adult patients with acute pain resulting from strains, sprains or sports or overuse-type injuries (twisted ankle, for instance). There had to be at least 10 participants in each treatment arm, with application of treatment at least once daily. Data collection and analysis Two review authors independently assessed trial quality and validity, and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Forty-seven studies were included; most compared topical NSAIDs in the form of a gel, spray, or cream with a similar placebo, with 3455 participants in the overall analysis of efficacy. For all topical NSAIDs combined, compared with placebo, the number needed to treat to benefit (NNT) for clinical success, equivalent to 50% pain relief, was 4.5 (3.9 to 5.3) for treatment periods of 6 to 14 days. Topical diclofenac, ibuprofen, ketoprofen, and piroxicam were of similar efficacy, but indomethacin and benzydamine were not significantly better than placebo. Local skin reactions were generally mild and transient, and did not differ from placebo. There were very few systemic adverse events or withdrawals due to adverse events. There were insufficient data to reliably compare individual topical NSAIDs with each other or the same oral NSAID. Authors’ conclusions Topical NSAIDs can provide good levels of pain relief, without the systemic adverse events associated with oral NSAIDs, when used to treat acute musculoskeletal conditions.

A Review of Topical Diclofenac Use in Musculoskeletal Disease  

PubMed Central

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed medications for the treatment of musculoskeletal disorders. Osteoarthritis is the most common form of arthritis in humans and its prevalence rises with age. Oral NSAIDs have potential associated toxicities that must be monitored for and can limit the use of these drugs in certain populations including people of older age. Topical NSAIDs are now being recognized as an option for the treatment strategy of osteoarthritis. We review the efficacy and safety of one of the most common topical NSAIDS, topical diclofenac, for the treatment of osteoarthritis.

Current topics in sports-related head injuries: a review.  

PubMed

We review the current topic in sports-related head injuries including acute subdural hematoma (ASDH), concussion, and chronic traumatic encephalopathy (CTE). Sports-related ASDH is a leading cause of death and severe morbidity in popular contact sports like American football in the USA and judo in Japan. It is thought that rotational acceleration is most likely to produce not only cerebral concussion but also ASDH due to the rupture of a parasagittal bridging vein, depending on the severity of the rotational acceleration injury. Repeated sports head injuries increase the risk for future concussion, cerebral swelling, ASDH or CTE. To avoid fatal consequences or CTE resulting from repeated concussions, an understanding of the criteria for a safe post-concussion return to play (RTP) is essential. Once diagnosed with a concussion, the athlete must not be allowed to RTP the same day and should not resume play before the concussion symptoms have completely resolved. If brain damage has been confirmed or a subdural hematoma is present, the athlete should not be allowed to participate in any contact sports. As much remains unknown regarding the pathogenesis and pathophysiology of sports-related concussion, ASDH, and CTE, basic and clinical studies are necessary to elucidate the crucial issues in sports-related head injuries.

However, predicting the future importance of scientific articles and authors is challenging due to the dynamic nature of literature networks and evolving research topics. Different from most previous studies aiming to rank the current importance of literatures and authors, we focus on \\emph{ranking the future popularity of new publications and young researchers} by proposing a unified ranking model to combine various available information. Specifically, we first propose to extract two kinds of text features, words and words co-occurrence to characterize innovative papers and authors.

Fueling the Future with Fungal Genomics  

SciTech Connect

Fungi play important roles across the range of current and future biofuel production processes. From crop/feedstock health to plant biomass saccharification, enzyme production to bioprocesses for producing ethanol, higher alcohols or future hydrocarbon biofuels, fungi are involved. Research and development are underway to understand the underlying biological processes and improve them to make bioenergy production efficient on an industrial scale. Genomics is the foundation of the systems biology approach that is being used to accelerate the research and development efforts across the spectrum of topic areas that impact biofuels production. In this review, we discuss past, current and future advances made possible by genomic analyses of the fungi that impact plant/feedstock health, degradation of lignocellulosic biomass and fermentation of sugars to ethanol, hydrocarbon biofuels and renewable chemicals.

Planetary protection implementation on future Mars lander missions  

NASA Technical Reports Server (NTRS)

A workshop was convened to discuss the subject of planetary protection implementation for Mars lander missions. It was sponsored and organized by the Exobiology Implementation Team of the U.S./Russian Joint Working Group on Space Biomedical and Life Support Systems. The objective of the workshop was to discuss planetary protection issues for the Russian Mars '94 mission, which is currently under development, as well as for additional future Mars lander missions including the planned Mars '96 and U.S. MESUR Pathfinder and Network missions. A series of invited presentations was made to ensure that workshop participants had access to information relevant to the planned discussions. The topics summarized in this report include exobiology science objectives for Mars exploration, current international policy on planetary protection, planetary protection requirements developed for earlier missions, mission plans and designs for future U.S. and Russian Mars landers, biological contamination of spacecraft components, and techniques for spacecraft bioload reduction. In addition, the recent recommendations of the U.S. Space Studies Board (SSB) on this subject were also summarized. Much of the discussion focused on the recommendations of the SSB. The SSB proposed relaxing the planetary protection requirements for those Mars lander missions that do not contain life detection experiments, but maintaining Viking-like requirements for those missions that do contain life detection experiments. The SSB recommendations were found to be acceptable as a guide for future missions, although many questions and concerns about interpretation were raised and are summarized. Significant among the concerns was the need for more quantitative guidelines to prevent misinterpretation by project offices and better access to and use of the Viking data base of bioassays to specify microbial burden targets. Among the questions raised were how will the SSB recommendations be integrated with existing Committee on Space Research (COSPAR) policy and how will they apply to and affect Mars '94, Mars '96, MESUR Pathfinder, and MESUR Network missions? One additional topic briefly considered at the workshop was the identification of some issues related to planetary protection considerations for Mars sample return missions. These issues will form the basis for a follow-on joint U.S./Russian workshop on that subject.

Hypertrophic cardiomyopathy in 2013: Current speculations and future perspectives  

PubMed Central

Hypertrophic cardiomyopathy (HCM), the most variable cardiac disease in terms of phenotypic presentation and clinical outcome, represents the most common inherited cardiomyopathic process with an autosomal dominant trait of inheritance. To date, more than 1400 mutations of myofilament proteins associated with the disease have been identified, most of them “private” ones. This striking allelic and locus heterogeneity of the disease certainly complicates the establishment of phenotype-genotype correlations. Additionally, topics pertaining to patients’ everyday lives, such as sudden cardiac death (SCD) risk stratification and prevention, along with disease prognosis, are grossly related to the genetic variation of HCM. This review incorporates contemporary research findings and addresses major aspects of HCM, including preclinical diagnosis, genetic analysis, left ventricular outflow tract obstruction and SCD. More specifically, the spectrum of genetic analysis, the selection of the best method for obstruction alleviation and the need for a unique and accurate factor for SCD risk stratification are only some of the controversial HCM issues discussed. Additionally, future perspectives concerning HCM and myocardial ischemia, as well as atrial fibrillation, are discussed. Rather than enumerating clinical studies and guidelines, challenging problems concerning the disease are critically appraised by this review, highlighting current speculations and recommending future directions.

The future of epidemiology.  

PubMed

In this article, the authors discuss current challenges and opportunities in epidemiology that will affect the field's future. Epidemiology is commonly considered the methodologic backbone for the fields of public health and outcomes research because its practitioners describe patterns of disease occurrence, identify risk factors and etiologic determinants, and demonstrate the usefulness of interventions. Like most aspects of science, epidemiology is in rapid flux. Several factors that are influencing and will continue to influence epidemiology and the health of the public include factors fundamental to framing the discipline of epidemiology (i.e., its means of communication, its methodologies, its access to data, its values, its population perspective), factors relating to scientific advances (e.g., genomics, comparative effectiveness in therapeutics), and factors shaping human health (e.g., increasing globalism, the environment, disease and lifestyle, demographics, infectious disease).

Predicting the earth's future  

NASA Technical Reports Server (NTRS)

The development of earth system models that will simulate the past and present and provide predictions of future conditions is essential now that human activities have the potential to induce changes in the planetary environment. Critical aspects of global change include its pervasiveness and ubiquity, its distribution in several distinct time-scale bands, and the interactions between the atmosphere, ocean, land surface, and the terrestrial and marine biospheres. A model of the earth system on the scale of decades to centuries, developed by the Earth System Science Committee (NASA) with the strategy of dividing by time scale rather than discipline, is presented and the requirements for observations to support the implementation of the model are reviewed.

NASA Astronauts on Soyuz: Experience and Lessons for the Future  

NASA Technical Reports Server (NTRS)

The U. S., Russia, and, China have each addressed the question of human-rating spacecraft. NASA's operational experience with human-rating primarily resides with Mercury, Gemini, Apollo, Space Shuttle, and International Space Station. NASA s latest developmental experience includes Constellation, X38, X33, and the Orbital Space Plane. If domestic commercial crew vehicles are used to transport astronauts to and from space, Soyuz is another example of methods that could be used to human-rate a spacecraft and to work with commercial spacecraft providers. For Soyuz, NASA's normal assurance practices were adapted. Building on NASA's Soyuz experience, this report contends all past, present, and future vehicles rely on a range of methods and techniques for human-rating assurance, the components of which include: requirements, conceptual development, prototype evaluations, configuration management, formal development reviews (safety, design, operations), component/system ground-testing, integrated flight tests, independent assessments, and launch readiness reviews. When constraints (cost, schedule, international) limit the depth/breadth of one or more preferred assurance means, ways are found to bolster the remaining areas. This report provides information exemplifying the above safety assurance model for consideration with commercial or foreign-government-designed spacecraft. Topics addressed include: U.S./Soviet-Russian government/agency agreements and engineering/safety assessments performed with lessons learned in historic U.S./Russian joint space ventures

The future of cerebral surgery: a kaleidoscope of opportunities.  

PubMed

The emerging future of cerebral surgery will witness the refined evolution of current techniques, as well as the introduction of numerous novel concepts. Clinical practice and basic science research will benefit greatly from their application. The sum of these efforts will result in continued minimalism and improved accuracy and efficiency of neurosurgical diagnostic and therapeutic methodologies.Initially, the refinement of current technologies will further enhance various aspects of cerebral surgery. Advances in computing power and information technology will speed data acquisition, storage, and transfer. Miniaturization of current devices will impact diverse areas, such as modulation of endoscopy and endovascular techniques. The increased penetrance of surgical technologies such as stereotactic radiosurgery, neuronavigation, intraoperative imaging, and implantable electrodes for neurodegenerative disorders and epilepsy will enhance the knowledge and experience in these areas and facilitate refinements and advances in these technologies. Further into the future, technologies that are currently relatively remote to surgical events will fundamentally alter the complexity and scale at which a neurological disease may be treated or investigated. Seemingly futuristic concepts will become ubiquitous in the daily experience of the neurosurgeon. These include diverse fields such as nanotechnology, virtual reality, and robotics. Ultimately, combining advances in multiple fields will yield progress in diverse realms such as brain tumor therapy, neuromodulation for psychiatric diseases, and neuroprosthetics. Operating room equipment and design will benefit from each of the aforementioned advances. In this work, we discuss new developments in three parts. In Part I, concepts in minimalism important for future cerebral surgery are discussed. These include concrete and abstract ideas in miniaturization, as well as recent and future work in microelectromechanical systems and nanotechnology. Part II presents advances in computational sciences and technological fields dependent on these developments. Future breakthroughs in the components of the "computer," including data storage, electrical circuitry, and computing hardware and techniques, are discussed. Additionally, important concepts in the refinement of virtual environments and the brain-machine interface are presented, as their incorporation into cerebral surgery is closely linked to advances in computing and electronics. Finally, Part III offers insights into the future evolution of surgical and nonsurgical diagnostic and therapeutic modalities that are important for the future cerebral surgeon. A number of topics relevant to cerebral surgery are discussed, including the operative environment, imaging technologies, endoscopy, robotics, neuromodulation, stem cell therapy, radiosurgery, and technical methods of restoration of neural function. Cerebral surgery in the near and distant future will reflect the application of these emerging technologies. As this article indicates, the key to maximizing the impact of these advancements in the clinical arena is continued collaboration between scientists and neurosurgeons, as well as the emergence of a neurosurgeon whose scientific grounding and technical focus are far removed from those of his predecessors.

Topicality and Social Impact: Diverse Messages but Focused Messengers  

E-print Network

Are users who comment on a variety of matters more likely to achieve high influence than those who delve into one focused field? Do general Twitter hashtags, such as #lol, tend to be more popular than novel ones, such as #instantlyinlove? Questions like these demand a way to detect topics hidden behind messages associated with an individual or a hashtag, and a gauge of similarity among these topics. Here we develop such an approach to identify clusters of similar hashtags by detecting communities in the hashtag co-occurrence network. Then the topical diversity of a user's interests is quantified by the entropy of her hashtags across different topic clusters. A similar measure is applied to hashtags, based on co-occurring tags. We find that high topical diversity of early adopters or co-occurring tags implies high future popularity of hashtags. In contrast, low diversity helps an individual accumulate social influence. In short, diverse messages and focused messengers are more likely to gain impact.

Precession electron diffraction - a topical review.  

PubMed

In the 20?years since precession electron diffraction (PED) was introduced, it has grown from a little-known niche technique to one that is seen as a cornerstone of electron crystallography. It is now used primarily in two ways. The first is to determine crystal structures, to identify lattice parameters and symmetry, and ultimately to solve the atomic structure ab initio. The second is, through connection with the microscope scanning system, to map the local orientation of the specimen to investigate crystal texture, rotation and strain at the nanometre scale. This topical review brings the reader up to date, highlighting recent successes using PED and providing some pointers to the future in terms of method development and how the technique can meet some of the needs of the X-ray crystallography community. Complementary electron techniques are also discussed, together with how a synergy of methods may provide the best approach to electron-based structure analysis. PMID:25610633

Topics in statistical mechanics  

SciTech Connect

This thesis deals with four independent topics in statistical mechanics: (1) the dimer problem is solved exactly for a hexagonal lattice with general boundary using a known generating function from the theory of partitions. It is shown that the leading term in the entropy depends on the shape of the boundary; (2) continuum models of percolation and self-avoiding walks are introduced with the property that their series expansions are sums over linear graphs with intrinsic combinatorial weights and explicit dimension dependence; (3) a constrained SOS model is used to describe the edge of a simple cubic crystal. Low and high temperature results are derived as well as the detailed behavior near the crystal facet; (4) the microscopic model of the lambda-transition involving atomic permutation cycles is reexamined. In particular, a new derivation of the two-component field theory model of the critical behavior is presented. Results for a lattice model originally proposed by Kikuchi are extended with a high temperature series expansion and Monte Carlo simulation. 30 references.

Topics on String Phenomenology  

E-print Network

These lectures present some topics of string phenomenology and contain two parts. In the first part, I review the possibility of lowering the string scale in the TeV region, that provides a theoretical framework for solving the mass hierarchy problem and unifying all interactions. The apparent weakness of gravity can then be accounted by the existence of large internal dimensions, in the submillimeter region, and transverse to a braneworld where our universe must be confined. I review the main properties of this scenario and its implications for observations at both particle colliders, and in non-accelerator gravity experiments. In the second part, I discuss a simple framework of toroidal string models with magnetized branes, that offers an interesting self-consistent setup for string phenomenology. I will present an algorithm for fixing the geometric parameters of the compactification, build calculable particle physics models such as a supersymmetric SU(5) Grand Unified Theory with three generations of quarks and leptons, and implement low energy supersymmetry breaking with gauge mediation that can be studied directly at the string level.

Unsupervised texture segmentation based on latent topic assignment  

NASA Astrophysics Data System (ADS)

We present an effective solution for unsupervised texture segmentation by taking advantage of the latent Dirichlet allocation (LDA) model. LDA is a generative topic model that is capable of hierarchically organizing discrete data including texts and images. We propose a new texture model by connecting texture primitives to the topic of LDA. The model is able to extract the characteristic features of a texture primitive and group them into a topic based on their frequencies of co-occurrence. Here, the feature descriptor is the connection of Haar-like features of multiple sizes. The segments of an image are finally obtained by identifying the homogeneous regions in the corresponding topic assignment map. The evaluation results for synthetic texture mosaics, remote sensing images, and natural scene images are illustrated.

The future of anaesthesiology  

PubMed Central

There was an era when bark of mandrake plant, boiled in wine was used to administer anesthesia. Ether, after reigning the kingdom of anaesthesiology for more than a century, came to be superseded by newer and newer agents. Anaesthesiology has witnessed tremendous developments since infancy. The introduction of advanced airway adjuncts, labour analgesia, patient controlled analgesia, fibreoptics, Bispectral Index monitors, workstations, simulators and robotic surgeries are only to name a further few. Anaesthesia for robotic surgery received much impetus and is still a dream to come true in many countries. But then, the rapid spin in technology and fast sophistication of medical field has even surpassed this. The next event to venture is entry of robots into human body made possible by a culmination of intricate medicine and fine technology that is Nanotechnology. This article briefly introduces the field of nanotechnology in relation to its potential benefits to the field of anaesthesiology. As with any new tecnique or application, nanotechnology as applied to anaesthesiology has tremendous potential for research and exploration. This article therefore orients the reader's mind towards the immense potential and benefits that can be tapped by carrying out further studies and experimentations.The literature was searched using databases, peer reviewed journals and books for over a period of one year (till December 2011). The search was carried out using keywords as nanotechnology, robotics, anesthesiology etc. Initially a master database was formed including human as well as animal studies. Later on the broad topic area was narrowed down to developments in nanotechnology as applied to anesthesiology. Further filtering of search results were done based on selection of researches and developments relating to local, regional and general anesthesia as well as critical care and pain and palliative care.

The future of memory  

NASA Astrophysics Data System (ADS)

In the not too distant future, the traditional memory and storage hierarchy of may be replaced by a single Storage Class Memory (SCM) device integrated on or near the logic processor. Traditional magnetic hard drives, NAND flash, DRAM, and higher level caches (L2 and up) will be replaced with a single high performance memory device. The Storage Class Memory paradigm will require high speed (< 100 ns read/write), excellent endurance (> 1012), nonvolatility (retention > 10 years), and low switching energies (< 10 pJ per switch). The International Technology Roadmap for Semiconductors (ITRS) has recently evaluated several potential candidates SCM technologies, including Resistive (or Redox) RAM, Spin Torque Transfer RAM (STT-MRAM), and phase change memory (PCM). All of these devices show potential well beyond that of current flash technologies and research efforts are underway to improve the endurance, write speeds, and scalabilities to be on-par with DRAM. This progress has interesting implications for space electronics: each of these emerging device technologies show excellent resistance to the types of radiation typically found in space applications. Commercially developed, high density storage class memory-based systems may include a memory that is physically radiation hard, and suitable for space applications without major shielding efforts. This paper reviews the Storage Class Memory concept, emerging memory devices, and possible applicability to radiation hardened electronics for space.

Topical timolol for small hemangiomas of infancy.  

PubMed

Propranolol has become the treatment of choice of large and complicated infantile hemangiomas. There is a controversy concerning the safety of systemic propranolol. Here we show that topical use of the beta-blocker timolol can also inhibit the growth and promote regression of infantile hemangiomas. In this case series we treated 11 infantile hemangiomas in nine children including six preterm babies with the nonselective betablocker timolol. A timolol containing gel was manufactured from an ophthalmic formulation of timolol 0.5% eyedrops. This gel was applied using a standardized occlusive dressing (Finn-Chambers) containing approximately 0.25?mg of timolol. In all infants topical timolol was associated with growth arrest, a reduction in redness and thickness within the first 2?weeks. Seven hemangiomas showed almost complete resolution, and four became much paler and thinner. No data are available on the transdermal absorption of timolol. Even supposing complete absorption of timolol from the occlusive dressing, a maximum dose of 0.25?mg of timolol would result per day and hemangioma. Regression of infantile hemangiomas treated using 0.5% timolol gel in this case series occurred earlier than spontaneous regression which is generally not observed before the age of 9-12?months. The promising results need to be verified in prospective randomized trials on topical beta blocker administration for infantile hemangiomas which should address dose, duration, and mode of application.

``Family Guides" to Hot Topics in Space Science and Astronomy  

NASA Astrophysics Data System (ADS)

We have undertaken the development, field testing, and dissemination of a new series of "Family Guides" on hot topics in space science and astronomy. Each Guide includes an innovative collection of puzzles, pictures, poetry, and projects, all designed to stimulate enjoyable co-learning, inquiry-based experiences between kids aged 6-12 and the caring adults in their lives. Family Guides generally intend to raise awareness and understanding of Earth's place in the wondrous Universe in which we live. The Guides endeavor to be accessible to those who are not familiar with astronomy. They coach adults how to lead inquiry with kids without knowing all the answers. They provide background on questions commonly asked by children and they challenge common misconceptions. The Guides also provide leads to more information and useful products related to family learning. Guide content is related to national science education standards and is valuable to home-schooled students as well as to educators who run family education programs or after-school programs. Although primarily intended for use in informal educational settings, many classroom teachers have expressed interest in the Guide's activities as engagement pieces for more formal lessons. We released the field test version of the Family Guide to the Sun in late summer 2003. In December 2003 we released the field test version of the Family Guide to Mars in time for use with educational programs associated with the Mars Exploration Rover landings. Future projects include Guides to Saturn and to the Search for Life Elsewhere. This paper will provide details of the Guides' contents and early results from field testing in various educational settings. We are still exploring the best ways to publish and effectively disseminate the Guides.

Current topical and systemic therapies for itch.  

PubMed

Itch is a common distressing symptom which may be caused by multifactorial aetiologies including inflammatory skin diseases, systemic diseases, neuropathic conditions and psychogenic disorders. Itch is a term used synonymously with pruritus and is defined as acute if it lasts less than 6 weeks or chronic if it persists for more than 6 weeks. It can have the same impact on the quality of life as chronic pain and shares many of the same pathophysiological pathways. Depending on the aetiology of the itch, different pathogenic mechanisms have been postulated with a number of mediators identified. These include histamine, leukotrienes, proteases, neuropeptides, cytokines and opioids, which may activate peripheral itch-mediating C-fibres via receptors on the nerve terminals and central neuronal pathways. Therefore, there is no single universally effective anti-itch treatment available. First-line treatments for itch include topical therapies, such as emollients, mild cleansers (low pH), topical anaesthetics, steroids, calcineurin inhibitors and coolants (menthol). Treatment with systemic therapies can vary according to the aetiology of the chronic itch. Non-sedating antihistamines are helpful in conditions such as urticaria where the itch is primarily histamine mediated. Although the itch of eczema is not mediated by histamine, sedating antihistamines at night are helpful to break the itch-scratch cycle. Chronic itch may also be treated with other systemic therapies, such as anticonvulsants, antidepressants as well as mu-opioid antagonists, kappa-opioid agonists and phototherapy, depending on the cause of the itch. This article summarises the topical and systemic therapies available with our current understanding of the pathophysiology of itch. PMID:25861788

Formulation, pharmacokinetics and pharmacodynamics of topical microbicides  

PubMed Central

The development of safe topical microbicides that effectively prevent human immunodeficiency virus (HIV) infection is a major goal in curbing the human immunodeficiency virus pandemic. A number of past failures resulting from mucosal toxicity or lack of efficacy have informed the field. Products that caused toxicity to the female genital tract mucosa, and thereby increased the likelihood of HIV acquisition, included nonoxynol 9, cellulose sulfate, and C31 G vaginal gel Savvy®. Topical products that were ineffective in preventing HIV infection include BufferGel®, Carraguard®, and PRO 2000®. Antiretroviral drugs such as tenofovir and dapivirine formulated into microbicide products have shown promise, but there is much to learn about ideal product formulation and acceptability, and drug distribution and disposition (pharmacokinetics). Current formulations for water-soluble molecules include vaginally or rectally applied gels, vaginal rings, films and tablets. Dosing strategies (e.g. coitally dependent or independent) will be based on the pharmacokinetics of the active ingredient and the tolerance for less than perfect adherence. PMID:22306523

Neoclassical Transport Including Collisional Nonlinearity  

SciTech Connect

In the standard {delta}f theory of neoclassical transport, the zeroth-order (Maxwellian) solution is obtained analytically via the solution of a nonlinear equation. The first-order correction {delta}f is subsequently computed as the solution of a linear, inhomogeneous equation that includes the linearized Fokker-Planck collision operator. This equation admits analytic solutions only in extreme asymptotic limits (banana, plateau, Pfirsch-Schlueter), and so must be solved numerically for realistic plasma parameters. Recently, numerical codes have appeared which attempt to compute the total distribution f more accurately than in the standard ordering by retaining some nonlinear terms related to finite-orbit width, while simultaneously reusing some form of the linearized collision operator. In this work we show that higher-order corrections to the distribution function may be unphysical if collisional nonlinearities are ignored.

Critical review of topical management of oral hairy leukoplakia  

PubMed Central

Oral hairy leukoplakia (OHL) is a disease associated with Epstein-Barr virus and human immunodeficiency virus infections. OHL is usually an asymptomatic lesion, but in some cases treatment is recommended to reestablish the normal characteristics of the tongue, to eliminate pathogenic microorganisms, to improve patient comfort and for cosmetic reasons. Proposed treatments for this condition include surgery, systemic antiviral treatment and topical management. Topical treatment is an inexpensive and safe therapy that is easy to apply, noninvasive, free of systemic adverse effects and effective over a long period of time. The aim of this study was to present a review of the literature for topical therapy for OHL. Gentian violet, retinoids, podophyllin, acyclovir and podophyllin associated with topical antiviral drugs were used to treat OHL. Reports with this focus are limited, and since 2010, no new studies have been published that discuss the efficacy of topical treatments for OHL. Podophyllin with acyclovir cream was found to be effective, causing regression of lesions with no recurrences. Additional searches are necessary to provide clinical evidence of topical management effectiveness. PMID:25032199

Reliability evaluation of electric power generation systems including the effects of energy limitation  

SciTech Connect

Most of the reliability studies, both single and multi-area, ignore the effect of the energy limitations. The limitation on available energy for the generating units can, however, have a significant effect on system reliability. This dissertation develops new analytical models for the reliability evaluation of electric power generation systems including the effects of energy limitation, so the reliability evaluation provides more realistic results for system planning and operation. In single area generation systems, energy limitation is modeled by using peak shaving method (PSM) and conditional convolution, with the equivalent load model. In multi-area generation systems, a probabilistic power flow model is used. The peak shaving method is extended to multi-area evaluation using cluster loads to model energy limitation. A controlled maximum flow method is proposed to reduce the sets generated in the recursive state space decomposition. The proposed methods are described and tested by using IEEE-RTS (Reliability Test System) and EPRI synthetic system. Future research topics are recommended.

Analysis of Smart Composite Structures Including Debonding  

NASA Technical Reports Server (NTRS)

Smart composite structures with distributed sensors and actuators have the capability to actively respond to a changing environment while offering significant weight savings and additional passive controllability through ply tailoring. Piezoelectric sensing and actuation of composite laminates is the most promising concept due to the static and dynamic control capabilities. Essential to the implementation of these smart composites are the development of accurate and efficient modeling techniques and experimental validation. This research addresses each of these important topics. A refined higher order theory is developed to model composite structures with surface bonded or embedded piezoelectric transducers. These transducers are used as both sensors and actuators for closed loop control. The theory accurately captures the transverse shear deformation through the thickness of the smart composite laminate while satisfying stress free boundary conditions on the free surfaces. The theory is extended to include the effect of debonding at the actuator-laminate interface. The developed analytical model is implemented using the finite element method utilizing an induced strain approach for computational efficiency. This allows general laminate geometries and boundary conditions to be analyzed. The state space control equations are developed to allow flexibility in the design of the control system. Circuit concepts are also discussed. Static and dynamic results of smart composite structures, obtained using the higher order theory, are correlated with available analytical data. Comparisons, including debonded laminates, are also made with a general purpose finite element code and available experimental data. Overall, very good agreement is observed. Convergence of the finite element implementation of the higher order theory is shown with exact solutions. Additional results demonstrate the utility of the developed theory to study piezoelectric actuation of composite laminates with pre-existing debonding. Significant changes in the modes shapes and reductions in the control authority result due to partially debonded actuators. An experimental investigation addresses practical issues, such as circuit design and implementation, associated with piezoelectric sensing and actuation of composite laminates. Composite specimens with piezoelectric transducers were designed, constructed and tested to validate the higher order theory. These specimens were tested with various stacking sequences, debonding lengths and gains for both open and closed loop cases. Frequency changes of 15% and damping on the order of more than 20% of critical damping, via closed loop control, was achieved. Correlation with the higher order theory is very good. Debonding is shown to adversely affect the open and closed loop frequencies, damping ratios, settling time and control authority.

Future trends in synergetics  

NASA Astrophysics Data System (ADS)

After a brief description of the goals of synergetics, basic concepts of this interdisciplinary field, such as order parameters and the slaving principles, are sketched. Close to instability points the dynamics of a complex system can be reduced to low dimensional dynamics, where fluctuations can be included. First steps towards the extension of the slaving principle towards delay equations and towards situations far away from instability points are outlined. While the problem of pattern formation has been at the focus of synergetics, new lines of research are the analysis of observed patterns and pattern recognition. The principle of the synergetic computer requires further elaborations. Teaching robots, using concepts of synergetics, may be an important task. New kinds of devices that may return to analogue processes seem to be feasible; here the parallelism of processes will be in the foreground of future research. First steps into this direction were done by studies of lasers and new kinds of semiconductor devices. According to this author’s opinion, physics will play an increasingly important role in medicine, especially in medical diagnosis. Here synergetics can be of help for instance in analysing MEG and EEG recordings, where first steps are reported. A challenging problem remains in how far physical devices can mimick brain functions. Pattern recognition by the synergetic computer and related devices as well as learning by robots are only first steps. It is hoped that the concept of order parameters and the slaving principle will be of use here also.

Food allergy affects 3.9% of US children and is increasing in prevalence. The current standard of care involves avoidance of the triggering food and treatment for accidental ingestions. While there is no current curative treatment, there are a number of therapeutic strategies under investigation. Allergen specific therapies include oral and sublingual immunotherapy with native food protein as well as recombinant food proteins. Allergen non-specific therapies include a Chinese herbal formula (FAHF-2) and the use of anti-IgE monoclonal antibody therapy. Although none of these treatments are ready for clinical use, these therapeutic strategies present promising options for the future of food allergy. PMID:22894951

Topical Antimicrobials for Burn Infections – An Update  

PubMed Central

The relentless rise in antibiotic resistance among pathogenic bacteria and fungi, coupled with the high susceptibility of burn wounds to infection, and the difficulty of systemically administered antibiotics to reach damaged tissue, taken together have made the development of novel topical antimicrobials for burn infections a fertile area of innovation for researchers and companies. We previously covered the existing patent literature in this area in 2010, but the notable progress made since then, has highlighted the need for an update to bring the reader up to date on recent developments. New patents in the areas of topically applied antibiotics and agents that can potentiate the action of existing antibiotics may extend their useful lifetime. Developments have also been made in biofilm-disrupting agents. Antimicrobial peptides are nature’s way for many life forms to defend themselves against attack by pathogens. Silver has long been known to be a highly active antimicrobial but new inorganic metal derivatives based on bismuth, copper and gallium have emerged. Halogens such as chlorine and iodine can be delivered by novel technologies. A variety of topically applied antimicrobials include chitosan preparations, usnic acid, ceragenins and XF porphyrins. Natural product derived antimicrobials such as tannins and essential oils have also been studied. Novel techniques to deliver reactive oxygen species and nitric oxide in situ have been developed. Light-mediated techniques include photodynamic therapy, ultraviolet irradiation, blue light, low-level laser therapy and titania photocatalysis. Passive immunotherapy employs antibodies against pathogens and their virulence factors. Finally an interesting new area uses therapeutic microorganisms such as phages, probiotic bacteria and protozoa to combat infections. PMID:24215506

Topical rubefacients for acute and chronic pain in adults  

PubMed Central

Background Rubefacients (containing salicylates or nicotinamides) cause irritation of the skin, and are believed to relieve various musculoskeletal pains. They are available on prescription, and are common components in over-the-counter remedies. A non-Cochrane review in 2004 found limited evidence for efficacy. Objectives To review current evidence for efficacy and safety of topically applied rubefacients in acute and chronic painful musculoskeletal conditions in adults. Search methods Cochrane CENTRAL, MEDLINE, EMBASE, the Oxford Pain Relief Database, and reference lists of articles were searched; last search December 2008. Selection criteria Randomised, double blind, placebo or active controlled clinical trials of topical rubefacient for musculoskeletal pain in adults, with at least 10 participants per treatment arm, and reporting outcomes at close to 7 (minimum 3, maximum 10) days for acute conditions and 14 (minimum 7) days or longer for chronic conditions. Data collection and analysis Two review authors independently assessed trials for inclusion and quality, and extracted data. Relative benefit or risk and number needed to treat to benefit or harm (NNT or NNH) were calculated with 95% confidence intervals (CI). Acute and chronic conditions were analysed separately. Main results Six placebo and one active controlled studies (560 and 137 participants) in acute pain, and seven placebo and two active controlled studies (489 and 90 participants) in chronic pain were included. All used topical salicylates. The evidence in acute conditions was not robust; using only better quality, valid studies, there was no difference between topical rubefacient and topical control, though overall, including lower quality studies, the NNT for clinical success compared with placebo was 3.2 (95% CI: 2.4 to 4.9). In chronic conditions the NNT was 6.2 (95% CI: 4.0 to 13) compared with topical placebo. Adverse events and withdrawals occurred more often with rubefacients than placebo, but analyses were sensitive to inclusion of individual studies, so not robust. There were insufficient data to draw conclusions against active controls. Authors’ conclusions The evidence does not support the use of topical rubefacients containing salicylates for acute injuries, and suggests that in chronic conditions their efficacy compares poorly with topical non-steroidal antiinflammatory drugs (NSAIDs). Topical salicylates seem to be relatively well tolerated in the short-term, based on limited data. There is no evidence at all for topical rubefacients with other components. PMID:19588430

Topics in elementary particle physics  

NASA Astrophysics Data System (ADS)

The author of this thesis discusses two topics in elementary particle physics: n-ary algebras and their applications to M-theory (Part I), and functional evolution and Renormalization Group flows (Part II). In part I, Lie algebra is extended to four different n-ary algebraic structure: generalized Lie algebra, Filippov algebra, Nambu algebra and Nambu-Poisson tensor; though there are still many other n-ary algebras. A natural property of Generalized Lie algebras — the Bremner identity, is studied, and proved with a totally different method from its original version. We extend Bremner identity to n-bracket cases, where n is an arbitrary odd integer. Filippov algebras do not focus on associativity, and are defined by the Fundamental identity. We add associativity to Filippov algebras, and give examples of how to construct Filippov algebras from su(2), bosonic oscillator, Virasoro algebra. We try to include fermionic charges into the ternary Virasoro-Witt algebra, but the attempt fails because fermionic charges keep generating new charges that make the algebra not closed. We also study the Bremner identity restriction on Nambu algebras and Nambu-Poisson tensors. So far, the only example 3-algebra being used in physics is the BLG model with 3-algebra A4, describing two M2-branes interactions. Its extension with Nambu algebra, BLG-NB model, is believed to describe infinite M2-branes condensation. Also, there is another propose for M2-brane interactions, the ABJM model, which is constructed by ordinary Lie algebra. We compare the symmetry properties between them, and discuss the possible approaches to include these three models into a grand unification theory. In Part II, we give an approximate solution for Schroeder's equations, based on series and conjugation methods. We use the logistic map as an example, and demonstrate that this approximate solution converges to known analytical solutions around the fixed point, around which the approximate solution is constructed. Although the closed-form solutions for Schroeder's equations can not always be approached analytically, by fitting the approximation solutions, one can still obtain closed-form solutions sometimes. Based on Schroeder's theory, approximate solutions for trajectories, velocities and potentials can also be constructed. The approximate solution is significantly useful to calculate the beta function in renormalization group trajectory. By "wrapping" the series solutions with the conjugations from different inverse functions, we generate different branches of the trajectory, and construct a counterexample for a folk theorem about limited cycles.

Topics in Leptogenesis  

SciTech Connect

Baryogenesis via leptogenesis provides an appealing mechanism to explain the observed baryon asymmetry of the Universe. Recent refinements in the understanding of the dynamics of leptogenesis include detailed studies of the effects of lepton flavor and of the role possibly played by the lepton asymmetries generated in the decays of the heavier singlet neutrinos N2,3. In this talk I present short a review of these recent developments in the theory of leptogenesis.

Safe futures for Java

A future is a simple and elegant abstraction that allows concurrency to be expressed often through a relatively small rewrite of a sequential program. In the absence of side-effects, futures serve as benign annotations that mark potentially concurrent regions of code. Unfortunately, when computation relies heavily on mutation as is the case in Java, its meaning is less clear, and

Topical Corticosteroid Addiction and Phobia  

PubMed Central

Corticosteroids, one of the most widely prescribed topical drugs, have been used for about six decades till date. However, rampant misuse and abuse down the years has given the drug a bad name. Topical steroid abuse may lead to two major problems which lie at the opposing ends of the psychosomatic spectrum. Topical steroid addiction, a phenomenon that came to be recognized about a decade after the introduction of the molecule is manifested as psychological distress and rebound phenomenon on stoppage of the drug. The rebound phenomenon, which can affect various parts of the body particularly the face and the genitalia has been reported by various names in the literature. TC phobia which lies at the opposite end of the psychiatric spectrum of steroid abuse has been reported particularly among parents of atopic children. Management of both conditions is difficult and frustrating. Psychological counseling and support can be of immense help in both the conditions. PMID:25284851

The need to include animal protection in public health policies  

PubMed Central

Many critical public health issues require non-traditional approaches. Although many novel strategies are used, one approach not widely applied involves improving the treatment of animals. Emerging infectious diseases are pressing public health challenges that could benefit from improving the treatment of animals. Other human health issues, that overlap with animal treatment issues, and that warrant further exploration, are medical research and domestic violence. The diverse nature of these health issues and their connection with animal treatment suggest that there may be other similar intersections. Public health would benefit by including the treatment of animals as a topic of study and policy development. PMID:23803712

Necrobiosis lipoidica (NL) is a chronic inflammatory skin disease that is difficult to treat. The etiology is unknown, but vascular abnormalities and immunologic factors have been implicated. We treated a patient with long-standing NL with multiple vascular risk factors (diabetes mellitus, protein S-deficiency, and antiphospholipid syndrome) with topical tacrolimus, a non-steroidal immunomodulator that causes no skin atrophy. After 12 weeks of topical tacrolimus (0.1%) ointment, our patient already showed a good remission with a significant decrease in inflammatory signs. PMID:20953573

Primary focal hyperhidrosis affects 3% of the US population; about the same number as psoriasis. More than half of these patients have primary focal axillary hyperhidrosis: sweating that is beyond what is anticipated or necessary for thermoregulation. Most topical therapies are based on aluminum salts, which work by a chemical reaction that forms plugs in the eccrine sweat ducts. Topical anticholinergics may also be used. Instruction on proper methods and timing of antiperspirants enhances effect and may be effective alone or in combination with other treatments in patients with hyperhidrosis. PMID:25152341

The Future of Modified Fibers  

SciTech Connect

The future of fiber technology for medical and specialty applications depends largely on the future needs of our civilization. It has been said that unmet needs drive the funding that sparks ideas. In this regard recent emphasis on United States homeland security has encouraged new bio-fiber research, resulting in the development of anti-bacterial fibers for producing clothing and filters to eliminate pathogens and enzyme-linked fibers to facilitate decontamination of nerve toxins from human skin [1]. Magnetic fibers may also have future security applications including fiber-based detectors for individual and material recognition. Interest in smart and interactive textiles is increasing with a projected average annual growth rate of 36% by 2009 [2]. More specific markets including medical textiles and enzymes will grow even more rapidly. Among the medical textiles are interactive wound dressings, implantable grafts, smart hygienic materials, and dialysis tubing. Some of the medical and specialty fibers inclusive of these types of product areas are discussed in this book. A recent review of the surface modification of fibers as therapeutic and diagnostic systems relevant to some of these new product areas has been published by Gupta [3]. In his review he examined current technology for medical textile structures [3] with a focus on woven medical textile materials.

This paper highlights some recent accomplishments regarding CFD numerical algorithm constructions for generation of discrete approximate solutions to classes of Reynolds-averaged Navier-Stokes equations. Following an overview of turbulent closure modeling, and development of appropriate conservation law systems, a Taylor weak-statement semi-discrete approximate solution algorithm is developed. Various forms for completion to the final linear algebra statement are cited, as are a range of candidate numerical linear algebra solution procedures. This development sequence emphasizes the key building blocks of a CFD RNS algorithm, including solution trial and test spaces, integration procedure and added numerical stability mechanisms. A range of numerical results are discussed focusing on key topics guiding future research directions.

IT-enabled Community Health Interventions: Challenges, Opportunities, and Future Directions

Rising health information technology (HIT) adoption and the increasing interoperability of health data have propelled the role of IT in community-wide health transformations. Disseminating the challenges and opportunities that the early adopters of community-wide HIT interventions have experienced is critical for empowering the growing demand for community-based health systems. This special issue of eGEMs addresses that need. This issue includes a variety of community-based HIT projects covering topics such as governance, informatics, and learning health systems. These projects represent a diverse set of stakeholders, a wide selection of data sources, and multiple information platforms to collate or exchange data. We hope that this special issue of eGEMs will be the first of several future issues dedicated to community-wide HIT transformations.

Recent developments in neurofibromatoses and RASopathies: management, diagnosis and current and future therapeutic avenues.  

PubMed

Neurofibromatosis type 1 (NF1) was the first RASopathy and is now one of many RASopathies that are caused by germline mutations in genes that encode components of the Ras/mitogen-activated protein kinase (MAPK) pathway. Their common underlying pathogenetic etiology causes significant overlap in phenotypic features which includes craniofacial dysmorphology, cardiac, cutaneous, musculoskeletal, GI and ocular abnormalities, and a predisposition to cancer. The proceedings from the symposium "Recent Developments in Neurofibromatoses (NF) and RASopathies: Management, Diagnosis and Current and Future Therapeutic Avenues" chronicle this timely and topical clinical translational research symposium. The overarching goal was to bring together clinicians, basic scientists, physician-scientists, advocate leaders, trainees, students and individuals with Ras pathway syndromes to discuss the most state-of-the-art basic science and clinical issues in an effort to spark collaborations directed towards the best practices and therapies for individuals with RASopathies.

Five Years From Now: Correlates of Older People's Expectation of Future Quality of Life.  

PubMed

Few studies have explored older people's expected future quality of life (QoL), despite evidence that perceptions of one's future influence healthy aging. Research on this topic should embrace a range of potential influences, including perceptions of one's neighborhood and region. This study examined expected QoL in a random sample of the population of Dalarna, a Swedish region. A self-completion questionnaire assessed demographic characteristics, current neighborhood and regional evaluations, self-evaluations, expectations for the future, and current and expected QoL. In total, 786 people aged ?65 years participated. A sequential multiple regression model explained 44% of the variance in older people's expected QoL, with self-reported health (sr (2) = .03), Expected Regional Opportunity (sr (2) = .03), and Perceived Regional Status (sr (2) = .02) having the strongest associations with expected QoL. Research on the importance of one's neighborhood to QoL in older people should encompass people's perceptions of their region, to better inform social policy for healthy aging. PMID:25651549

Constructed wetlands, 1991-2011: a review of research development, current trends, and future directions.  

PubMed

This study explores a bibliometric approach to quantitatively evaluate global scientific constructed wetlands research, and statistically assess current trends, and future directions using the Science Citation Index Expanded (SCI-EXPANDED) database from 1991 to 2011. Articles referencing constructed wetlands were analyzed by accessing the following: publication language, output characteristics, publication performance by country and institution, author keywords, title words, and KeyWords Plus. Synthetically analyzing three keyword types, we concluded that the dominant constructed wetlands research hotspots from 1991 to 2011 included water, nutrients, plants, and flow. These four hotspots remained the most dominant research areas throughout our study period, and are predicted to remain the top research emphases in the near future. "Soil" also exhibited a notable increase since 2005, and is likely to become another notable area of research interest in the future. "Phytoremediation" and "horizontal" were not identified in 1991-1995, but exhibited marked increases from 136th (0.5%) and 169th (0.7%) in 1996-2000, to 9th (3.8%) and 11th (4.3%) in 2006-2011, respectively. Therefore, given the heightened attention during the last 15 years, these topics are likely to become a primary research focus in upcoming years. PMID:23134766

The future of organic photovoltaics.  

PubMed

Increasing global demand for energy, along with dwindling fossil fuel resources and a better understanding of the hidden costs associated with these energy sources, have spurred substantial political, academic, and industrial interest in alternative energy resources. Photovoltaics based on organic semiconductors have emerged as promising low-cost alternatives for electricity generation that relies on sunlight. In this tutorial review we discuss the relevance of these organic photovoltaics beginning with some of the economic drivers for these technologies. We then examine the basic properties of these devices, including operation and materials requirements, in addition to presenting the development of the field from a historical perspective. Potential future directions are also briefly discussed. This tutorial review is intended to be an essential overview of the progress of the field, in addition to aiding in the discussion of the future of OPV technologies. PMID:25198769

Constructing topic models of Internet of Things for information processing.  

PubMed

Internet of Things (IoT) is regarded as a remarkable development of the modern information technology. There is abundant digital products data on the IoT, linking with multiple types of objects/entities. Those associated entities carry rich information and usually in the form of query records. Therefore, constructing high quality topic hierarchies that can capture the term distribution of each product record enables us to better understand users' search intent and benefits tasks such as taxonomy construction, recommendation systems, and other communications solutions for the future IoT. In this paper, we propose a novel record entity topic model (RETM) for IoT environment that is associated with a set of entities and records and a Gibbs sampling-based algorithm is proposed to learn the model. We conduct extensive experiments on real-world datasets and compare our approach with existing methods to demonstrate the advantage of our approach. PMID:25110737

Including birefringence into time evolution of CMB: current and future constraints  

NASA Astrophysics Data System (ADS)

We introduce birefringence effects within the propagation history of CMB, considering the two cases of a constant effect and of an effect that increases linearly in time, as the rotation of polarization induced by birefringence accumulates during photon propagation. Both cases result into a mixing of E and B modes before lensing effects take place, thus leading to the fact that lensing is acting on spectra that are already mixed because of birefringence. Moreover, if the polarization rotation angle increases during propagation, birefringence affects more the large scales that the small scales. We put constraints on the two cases using data from WMAP 9yr and BICEP 2013 and compare these results with the constraints obtained when the usual procedure of rotating the final power spectra is adopted, finding that this dataset combination is unable to distinguish between effects, but it nevertheless hints for a non vanishing value of the polarization rotation angle. We also forecast the sensitivity that will be obtained using data from Planck and PolarBear, highlighting how this combination is capable to rule out a vanishing birefringence angle, but still unable to distinguish the different scenarios. Nevertheless, we find that the combination of Planck and PolarBear is sensitive enough to highlight the existence of degeneracies between birefringence rotation and gravitational lensing of CMB photons, possibly leading to false detection of non standard lensing effects if birefringence is neglected.

Feeding a future world.  

PubMed

This article provides an overview of future prospects for feeding the world's growing population. The discussion focuses on obstacles such as limited agricultural land, degraded soil and water, and water shortages. The evidence suggests that sustainability is declining, especially in poor, food-deficit countries with growing populations. The world is segregated into the haves, the poor have-nots, and the rich have-nots. North America, Europe, and Australia have enough cropland to feed their populations. The poor have-nots are located mostly in sub-Saharan Africa, 7 countries each in the Middle East and Latin America, 6 in Oceania, and the rest in Central and South Asia. The poor have-nots amount to 3 billion out of 6 billion total population. The rich have-nots include countries such as Japan and Singapore, plus China, Indonesia, Peru, Chile, and Saudi Arabia and other Gulf states. The rich have-nots must import food. The world grain harvest is no longer tripling. Per person yields have declined. Increasing food productivity must rely on existing lands. The size of family farms has declined. Almost 2 billion hectares of crop and grazing land is degraded. Yields from irrigated land that are 33% of world food supply have declined. In 1990, 28 countries with 335 million people faced chronic water shortages or scarcity. Water is being polluted. Fish stocks are being depleted. Genetic diversity is being lost. In 182 food deficit countries, population growth must be slowed, and agriculture must be sustainable. Food is neither produced nor consumed equitably. Malnutrition is caused by poverty. Food security cannot be achieved if land and water become increasingly degraded or lost. PMID:12348766

Looking back, to the future of circulating tumor cells.  

PubMed

Detection and analysis of circulating tumor cells (CTCs) from patients with metastatic malignancies have become active areas of research in recent years. CTC enumeration has already proven useful in establishing prognosis for patients with metastatic breast, colon, and prostate cancer. More recently, studies are going beyond enumeration, exploring the CTCs as a means to better understand the mechanisms of tumorigenesis, invasion, and metastasis and the value of CTC characterization for prognosis and tailoring of treatment. Analysis of CTC subpopulations, for example, is highlighting the importance of the epithelial to mesenchymal transition (EMT), a process which may be crucial for allowing tumors to invade into and grow at sites distant from the original tumor site. Similarly, the detection of CTCs expressing markers of stemness may also have important implications for treatment resistance. Genomic analysis of CTC and CTC subpopulations may allow for selection of novel therapeutic targets to combat treatment resistance. CTCs become a particularly valuable biospecimen resource when tissue biopsies are unavailable or not feasible and liquid biopsies allow for serial monitoring. Lastly, cultures of patient-derived CTCs may allow for an evaluation of therapeutic strategies performed ex vivo and in real time. This review article will focus on these developments, starting with the CTC pathogenesis, going on to discuss the different platforms available for CTC isolation and their use to date in these arenas, then will explore multiple topics including the existing data concerning CTC subpopulations and their clinical relevance, genomic characterization, and lastly, avenues for future research.

Flow and Noise Control: Review and Assessment of Future Directions  

NASA Technical Reports Server (NTRS)

Technologies for developing radically new aerovehicles that would combine quantum leaps in cost, safety, and performance benefits with environmental friendliness have appeared on the horizon. This report provides both an assessment of the current state-of-the-art in flow and noise control and a vision for the potential gains to be made, in terms of performance benefit for civil and military aircraft and a unique potential for noise reduction, via future advances in flow and noise technologies. This report outlines specific areas of research that will enable the breakthroughs necessary to bring this vision to reality. Recent developments in many topics within flow and noise control are reviewed. The flow control overview provides succinct summaries of various approaches for drag reduction and improved maneuvering. Both exterior and interior noise problems are examined, including dominant noise sources, physics of noise generation and propagation, and both established and proposed concepts for noise reduction. Synergy between flow and noise control is a focus and, more broadly, the need to pursue research in a more concurrent approach involving multiple disciplines. Also discussed are emerging technologies such as nanotechnology that may have a significant impact on the progress of flow and noise control.

The future of research in female pelvic medicine.  

PubMed

Female pelvic medicine and reconstructive surgery (FPMRS) was recently recognized as a subspecialty by the American Board of Medical Specialties (ABMS). FPMRS treats female pelvic disorders (FPD) including pelvic organ prolapse (POP), urinary incontinence (UI), fecal incontinence (FI), lower urinary tract symptoms (LUTS), lower urinary tract infections (UTI), pelvic pain, and female sexual dysfunction (FSD). These conditions affect large numbers of individuals, resulting in significant patient, societal, medical, and financial burdens. Given that treatments utilize both medical and surgical approaches, areas of research in FPD necessarily cover a gamut of topics, ranging from mechanistically driven basic science research to randomized controlled trials. While basic science research is slow to impact clinical care, transformational changes in a field occur through basic investigations. On the other hand, clinical research yields incremental changes to clinical care. Basic research intends to change understanding whereas clinical research intends to change practice. However, the best approach is to incorporate both basic and clinical research into a translational program which makes new discoveries and effects positive changes to clinical practice. This review examines current research in FPD, with focus on translational potential, and ponders the future of FPD research. With a goal of improving the care and outcomes in patients with FPD, a strategic collaboration of stakeholders (patients, advocacy groups, physicians, researchers, professional medical associations, legislators, governmental biomedical research agencies, pharmaceutical companies, and medical device companies) is an absolute requirement in order to generate funding needed for FPD translational research.

EDITORIAL: International Workshop on Current Topics in Monte Carlo Treatment Planning  

NASA Astrophysics Data System (ADS)

The use of Monte Carlo particle transport simulations in radiotherapy was pioneered in the early nineteen-seventies, but it was not until the eighties that they gained recognition as an essential research tool for radiation dosimetry, health physics and later on for radiation therapy treatment planning. Since the mid-nineties, there has been a boom in the number of workers using MC techniques in radiotherapy, and the quantity of papers published on the subject. Research and applications of MC techniques in radiotherapy span a very wide range from fundamental studies of cross sections and development of particle transport algorithms, to clinical evaluation of treatment plans for a variety of radiotherapy modalities. The International Workshop on Current Topics in Monte Carlo Treatment Planning took place at Montreal General Hospital, which is part of McGill University, halfway up Mount Royal on Montreal Island. It was held from 3-5 May, 2004, right after the freezing winter has lost its grip on Canada. About 120 workers attended the Workshop, representing 18 countries. Most of the pioneers in the field were present but also a large group of young scientists. In a very full programme, 41 long papers were presented (of which 12 were invited) and 20 posters were on display during the whole meeting. The topics covered included the latest developments in MC algorithms, statistical issues, source modelling and MC treatment planning for photon, electron and proton treatments. The final day was entirely devoted to clinical implementation issues. Monte Carlo radiotherapy treatment planning has only now made a slow entrée in the clinical environment, taking considerably longer than envisaged ten years ago. Of the twenty-five papers in this dedicated special issue, about a quarter deal with this topic, with probably many more studies to follow in the near future. If anything, we hope the Workshop served as an accelerator for more clinical evaluation of MC applications. The remainder of the papers in this issue demonstrate that there is still plenty of work to be undertaken on other topics such as source modelling, calculation speed, data analysis, and development of user-friendly applications. We acknowledge the financial support of the National Cancer Institute of Canada, the Institute of Cancer Research of the Canadian Institutes of Health Research, the Research Grants Office and the Post Graduate Student Society of McGill University, and the Institute of Physics Publishing (IOPP). A final word of thanks goes out to all of those who contributed to the successful Workshop: our local medical physics students and staff, the many colleagues who acted as guest associate editors for the reviewing process, the IOPP staff, and the authors who generated new and exciting work.

Public money and human purpose: The future of taxes  

SciTech Connect

Most countries use taxes and subsidies that undermine the well-being of both the taxpayers and the environment. But there are some positive-and now proven alternatives. One of the most powerfull tools that a government can use to guide its economy is its tax code. What politicians often overlook is that even though taxes are inevitable distortionary ones are not. In fact some taxes do no harm to the economy and other such as pollution taxes actually help it to work better. However there is a chronic tendency to undertax destructive activities such as pollution and resource depletion activities which can threaten long term economic security. By making environmental destruction cheap or even free governments let people and businesses ignore the costs they imposed on others and on the future. This article explores the possibilities of turning today`s taxing philosophy and subsidizing priorities completely around. To shore up economic security and brake economic decline good activities need to be taxed less. To preserve the environmental viability of modern economies over the long term, bad activities need to be taxed more. The topics discussed include the following: What should Tax codes do: (1) shift from taxing income and sales to taxing exploitation or resources, when that exploitation generates windfall profits; (2) Calibrate the new taxes so polluters and depleters will feel the costs of the harm they do others of their own and future generations; (3) shape the tax code to help people participate and survive in the modern economy; What Will Fiscal Reform Do To Businesses? 2 tabs.

Tales of future weather  

NASA Astrophysics Data System (ADS)

Society is vulnerable to extreme weather events and, by extension, to human impacts on future events. As climate changes weather patterns will change. The search is on for more effective methodologies to aid decision-makers both in mitigation to avoid climate change and in adaptation to changes. The traditional approach uses ensembles of climate model simulations, statistical bias correction, downscaling to the spatial and temporal scales relevant to decision-makers, and then translation into quantities of interest. The veracity of this approach cannot be tested, and it faces in-principle challenges. Alternatively, numerical weather prediction models in a hypothetical climate setting can provide tailored narratives for high-resolution simulations of high-impact weather in a future climate. This 'tales of future weather' approach will aid in the interpretation of lower-resolution simulations. Arguably, it potentially provides complementary, more realistic and more physically consistent pictures of what future weather might look like.

The MY NASA DATA Project: Preparing Future Earth and Environmental Scientists, and Future Citizens  

NASA Astrophysics Data System (ADS)

For the past 5 years, the MY NASA DATA (MND) project at NASA Langley has developed and adapted tools and materials aimed at enabling student access to real NASA Earth science satellite data. These include web visualization tools including Google Earth capabilities, but also GPS and graphing calculator exercises, Excel spreadsheet analyses, and more. The project team, NASA scientists, and over 80 classroom science teachers from around the country, have created over 85 lesson plans and science fair project ideas that demonstrate NASA satellite data use in the classroom. With over 150 Earth science parameters to choose from, the MND Live Access Server enables scientific inquiry on numerous interconnected Earth and environmental science topics about the Earth system. Teachers involved in the project report a number of benefits, including networking with other teachers nationwide who emphasize data collection and analysis in the classroom, as well as learning about other NASA resources and programs for educators. They also indicate that the MND website enhances the inquiry process and facilitates the formation of testable questions by students (a task that is typically difficult for students to do). MND makes science come alive for students because it allows them to develop their own questions using the same data scientists use. MND also provides educators with a rich venue for science practice skills, which are often overlooked in traditional curricula as teachers concentrate on state and national standards. A teacher in a disadvantaged school reports that her students are not exposed to many educational experiences outside the classroom. MND allows inner city students to be a part of NASA directly. They are able to use the same information that scientists are using and this gives them inspiration. In all classrooms, the MND microsets move students out of their local area to explore global data and then zoom back into their homes realizing that they are a part of the global Earth System. These armchair explorers learn to unite datasets in a region to learn about places like and unlike where they live. In a world that's becoming smaller and smaller with the aid of technology, projects like MND prepare our students for their global future. A teacher located in an area of California strongly impacted by pollution and potential climate changes noted that this project makes available data that are very relevant to issues that will affect her students' lives. She points out that not all scientific information they currently see is in a form that is understandable to an educated citizen, and that the experience with MND will enable her students to have better than average skills not only for deciphering scientific maps and graphs; but also for creating maps and graphics that successfully convey information to others.

Burst topic discovery and trend tracing based on Storm  

NASA Astrophysics Data System (ADS)

With the rapid development of the Internet and the promotion of mobile Internet, microblogs have become a major source and route of transmission for public opinion, including burst topics that are caused by emergencies. To facilitate real time mining of a large range of burst topics, in this paper, we proposed a method to discover burst topics in real time and trace their trends based on the variation trends of word frequencies. First, for the variation trend of the words in microblogs, we adopt a non-homogeneous Poisson process model to fit the data. To represent the heat and trend of the words, we introduce heat degree factor and trend degree factor and realise the real time discovery and trend tracing of the burst topics based on these two factors. Second, to improve the computing performance, this paper was based on the Storm stream computing framework for real time computing. Finally, the experimental results indicate that by adjusting the observation window size and trend degree threshold, topics with different cycles and different burst strengths can be discovered.

Topical nonsteroidal anti-inflammatory drugs for the treatment of pain due to soft tissue injury: diclofenac epolamine topical patch.  

PubMed

The objective of this article is to review published clinical data on diclofenac epolamine topical patch 1.3% (DETP) in the treatment of acute soft tissue injuries, such as strains, sprains, and contusions. Review of published literature on topical nonsteroidal anti-inflammatory drugs (NSAIDs), diclofenac, and DETP in patients with acute soft tissue injuries was included. Relevant literature was identified on MEDLINE using the search terms topical NSAIDs, diclofenac, diclofenac epolamine, acute pain, sports injury, soft tissue injury, strain, sprain, and contusion, and from citations in retrieved articles covering the years 1978-2008. Review of published, randomized clinical trials and meta-analyses shows that topical NSAIDs are significantly more effective than placebo in relieving acute pain; the pooled average relative benefit was 1.7 (95% confidence interval, 1.5-1.9). In a limited number of comparisons, topical and oral NSAIDs provided comparable pain relief, but the use of topical agents produced lower plasma drug concentrations and fewer systemic adverse events (AEs). The physical-chemical properties of diclofenac epolamine make it well suited for topical use. In patients with acute soft tissue injuries treated with DETP, clinical data report an analgesic benefit within hours of the first application, and significant pain relief relative to placebo within 3 days. Moreover, DETP displayed tolerability comparable with placebo; the most common AEs were pruritus and other application site reactions. Review of published literature suggests that DETP is generally safe and well tolerated, clinically efficacious, and a rational treatment option for patients experiencing acute pain associated with strains, sprains, and contusions, and other localized painful conditions.

FUTURE CLIMATE ANALYSIS  

SciTech Connect

This Analysis/Model Report (AMR) documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain (YM), Nevada (Figure l), the site of a potential repository for high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this AMR provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the infiltration model (USGS 2000) and for the total system performance assessment for the Site Recommendation (TSPA-SR) at YM. Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one method, among many, of establishing upper and lower bounds for future climate estimates. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog.

[The future of vascular medicine].  

PubMed

In the future vascular medicine will still have a great impact on health of people. It should be noted that the aging of the population does not lead to a dramatic increase in patient numbers, but will be associated with a changing spectrum of co-morbidities. In addition, vascular medical research has to include the intensive care special features of vascular patients, the involvement of vascular medicine in a holistic concept of fast-track surgery, a geriatric-oriented intensive monitoring and early geriatric rehabilitation. For the future acceptance of vascular medicine as a separate subject area under delimitation of cardiology and radiology is important. On the other hand, the subject is so complex and will become more complex in future specialisations that mixing of surgery and angiology is desirable, with the aim to preserve the vascular surgical knowledge and skills on par with the medical and interventional measures and further develop them. Only large, interdisciplinary guided vascular centres will be able to provide timely diagnosis and therapy, to deal with the growing multi-morbidity of the patient, to perform complex therapies even in an acute emergency and due to sufficient number of cases to present with well-trained and experienced teams. These requirements are mandatory to decrease patients' mortality step by step. PMID:25313887

Future Climate Analysis  

SciTech Connect

This Analysis/Model Report (AMR) documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain (YM), Nevada (Figure 1), the site of a potential repository for high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this AMR provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the infiltration model (USGS 2000) and for the total system performance assessment for the Site Recommendation (TSPA-SR) at YM. Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one method, among many, of establishing upper and lower bounds for future climate estimates. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog. Revision 00 of this AMR was prepared in accordance with the ''Work Direction and Planning Document for Future Climate Analysis'' (Peterman 1999) under Interagency Agreement DE-AI08-97NV12033 with the U.S. Department of Energy (DOE). The planning document for the technical scope, content, and management of ICN 01 of this AMR is the ''Technical Work Plan for Unsaturated Zone (UZ) Flow and Transport Process Model Report'' (BSC 2001a). The scope for the TBV resolution actions in this ICN is described in the ''Technical Work Plan for: Integrated Management of Technical Product Input Department''. (BSC 2001b, Addendum B, Section 4.1).

Technological developments and future perspectives on graphene-based metamaterials: a primer for neurosurgeons.  

PubMed

Graphene, a monolayer atomic-scale honeycomb lattice of carbon atoms, has been considered the greatest revolution in metamaterials research in the past 5 years. Its developers were awarded the Nobel Prize in Physics in 2010, and massive funding has been directed to graphene-based experimental research in the last years. For instance, an international scientific collaboration has recently received a €1 billion grant from the European Flagship Initiative, the largest amount of financial resources ever granted for a single research project in the history of modern science. Because of graphene's unique optical, thermal, mechanical, electronic, and quantum properties, the incorporation of graphene-based metamaterials to biomedical applications is expected to lead to major technological breakthroughs in the next few decades. Current frontline research in graphene technology includes the development of high-performance, lightweight, and malleable electronic devices, new optical modulators, ultracapacitors, molecular biodevices, organic photovoltaic cells, lithium-ion microbatteries, frequency multipliers, quantum dots, and integrated circuits, just to mention a few. With such advances, graphene technology is expected to significantly impact several areas of neurosurgery, including neuro-oncology, neurointensive care, neuroregeneration research, peripheral nerve surgery, functional neurosurgery, and spine surgery. In this topic review, the authors provide a basic introduction to the main electrophysical properties of graphene. Additionally, future perspectives of ongoing frontline investigations on this new metamaterial are discussed, with special emphasis on those research fields that are expected to most substantially impact experimental and clinical neurosurgery in the near future.

NASA's Future X-ray Missions: From Constellation-X to Generation-X  

NASA Technical Reports Server (NTRS)

Among the most important topics in modern astrophysics are the formation and evolution of supermassive black holes in concert with galaxy bulges, the nature of the dark energy equation of state, and the self-regulating symmetry imposed by both stellar and AGN feedback. All of these topics are readily addressed with observations at X-ray wavelengths. NASA's next major X-ray observatory is Constellation-X, which is being developed to perform spatially resolved high-resolution X-ray spectroscopy. Con-X will directly measure the physical properties of material near black holes' last stable orbits and the absolute element abundances and velocities of hot gas in clusters of galaxies. The Con-X mission will be described, as well as its successor, Generation-X (anticipated to fly approx.1 decade after Con-X). After describing these missions and their driving science areas, the talk will focus on areas in which Chandra observing programs may enable science with future X-ray observatories. These areas include a possible ultra-deep Chandra imaging survey as an early Universe pathfinder, a large program to spatially resolve the hot intracluster medium of massive clusters to aid dark energy measurements, and possible deep spectroscopic observations to aid in preparatory theoretical atomic physics work needed for interpreting Con-X spectra.

Hyperphagia: Current Concepts and Future Directions Proceedings of the 2nd International Conference on Hyperphagia  

PubMed Central

Objective Hyperphagia is a central feature of inherited disorders (e.g., Prader–Willi Syndrome) in which obesity is a primary phenotypic component. Hyperphagia may also contribute to obesity as observed in the general population, thus raising the potential importance of common underlying mechanisms and treatments. Substantial gaps in understanding the molecular basis of inherited hyperphagia syndromes are present as are a lack of mechanistic of mechanistic targets that can serve as a basis for pharmacologic and behavioral treatments. Design and Methods International conference with 28 experts, including scientists and caregivers, providing presentations, panel discussions, and debates. Results The reviewed collective research and clinical experience provides a critical body of new and novel information on hyperphagia at levels ranging from molecular to population. Gaps in understanding and tools needed for additional research were identified. Conclusions This report documents the full scope of important topics reviewed at a comprehensive international meeting devoted to the topic of hyperphagia and identifies key areas for future funding and research.

Topical treatment of alopecia areata.  

PubMed

It has been shown previously that alopecia areata can be treated with dinitrochlorobenzene (DNCB) and other contact allergens. Whether these agents work by inducing immunologic stimulation or simply a nonspecific inflammatory reaction has not been definitively demonstrated. To test the relative importance of these two mechanisms, we have randomly studied 22 patients with alopecia areata to whom either DNCB or croton oil was applied topically. Sixty-three percent of patients without spontaneous regrowth of hair regrew hair after DNCB application. None of those treated with croton oil regrew hair when treated later with DNCB. Therefore, a proved contact allergen was shown to be required for therapeutic success. Patient acceptance of the induced contact dermatitis was excellent. In light of recent data on the mutagenicity of DNCB to bacteria, other contact allergens for topical immunotherapy are being sought. PMID:7259216

Cooperating with the future  

NASA Astrophysics Data System (ADS)

Overexploitation of renewable resources today has a high cost on the welfare of future generations. Unlike in other public goods games, however, future generations cannot reciprocate actions made today. What mechanisms can maintain cooperation with the future? To answer this question, we devise a new experimental paradigm, the `Intergenerational Goods Game'. A line-up of successive groups (generations) can each either extract a resource to exhaustion or leave something for the next group. Exhausting the resource maximizes the payoff for the present generation, but leaves all future generations empty-handed. Here we show that the resource is almost always destroyed if extraction decisions are made individually. This failure to cooperate with the future is driven primarily by a minority of individuals who extract far more than what is sustainable. In contrast, when extractions are democratically decided by vote, the resource is consistently sustained. Voting is effective for two reasons. First, it allows a majority of cooperators to restrain defectors. Second, it reassures conditional cooperators that their efforts are not futile. Voting, however, only promotes sustainability if it is binding for all involved. Our results have implications for policy interventions designed to sustain intergenerational public goods.
