Collaboration and Inquiry: Cornell University Partnerships with Rural School Districts  

NASA Astrophysics Data System (ADS)

Cornell University's location provides valuable opportunities for university-community collaboration. Schools in the area tend to be rural, with limited access to resources. Two projects in place at Cornell provide opportunities for collaboration between graduate students and local K-12 schools. These programs yield benefits for K-12 students by exposing them to resources (and expertise) otherwise unavailable to them; for K-12 teachers, by providing access to knowledge and resources brought to them by the graduate students; and for the graduate students who participate in the program, by giving them opportunities to teach and design curricula. The two programs provide options for outreach that fit many schedules, teaching goals, and interests. The Graduate Student School Outreach Program (GSSOP) is open to all graduate students and local K-12 teachers. Students and teachers often participate for several years in a row. Graduate students prepare a 6-8 session "mini-course" in an area of their interest, and they are matched to local teachers with similar interests or needs. Graduate student participants are required to submit a final formatted curriculum for the lessons that they have taught, and these curricula are made available to the public on the GSSOP web site. GSSOP is currently in its twelfth year as a student-coordinated program, and its funding comes primarily from Cornell's Public Service Center and alumni donations. The Cornell Science Inquiry Partnership (CSIP) provides an opportunity for graduate students in the sciences to participate in longer-term collaborations with regional schools. CSIP is administered under the National Science Foundation GK12 initiative and is currently in its fourth year. CSIP fellows make a year-long commitment to teaching and outreach and receive a full fellowship. Fellows may work with several middle- or high-school teachers over the course of the year, and they may teach many lessons over different time scales. As in GSSOP, CSIP fellows prepare curricula that are made available to the public. CSIP courses focus on inquiry-based instruction, and fellows attend weekly seminars in which inquiry-based teaching and lesson planning strategies and theory are discussed.

Feline dermatology at Cornell University: 1407 cases (1988-2003).  

PubMed

Medical records of 1407 cats with dermatologic diagnoses made at Cornell University teaching hospital from 1988 to 2003 were tabulated. We expressed the diagnoses as counts, percentages of the cats with dermatologic disease (1407) and percentages of all cats seen at the university hospital (22,135) during the same period. A total of 1887 diagnoses were made in the 1407 cats. We compared the age, sex and breed group of our cases with all those 22,135 cats in ('1-by-c') ?(2) tests in which the hospital population was considered a standard (rather than a 'sample'). The 10 most common dermatoses, their counts, and the proportions of dermatologic diagnoses and of the total cat population that the cats with these dermatoses represented were: allergy (298; 15.8%; 1.35%), atopic dermatitis (194; 10.3%; 0.88%), bacterial folliculitis/furunculosis (189; 10.0%; 0.85%), otodectic mange (115; 6.1%; 0.52%), flea infestation (99; 5.2%; 0.45%), feline acne (74; 3.9%; 0.33%), flea-bite allergy (70; 3.7%; 0.32%), cutaneous adverse drug reaction (56; 3.0%; 0.25%), idiopathic eosinophilic-granuloma complex (55; 2.9%; 0.25%) and abscess (51; 2.7%; 0.23%). Allergies of all types, combined, accounted for 32.7% of all the feline dermatoses. Relative to the standard of the total hospital population, cats <2 years old and females (both intact and spayed) were significantly under-represented (all P?0.001) in the dermatologic case series. In contrast, Himalayans (compared with domestic short- or longhair, Persian, Siamese and other breeds) and males (both intact and neutered) were significantly over-represented (all P ?0.001).

CLEO-c Data from the Laboratory for Elementary-Particle Physics (LEPP) at Cornell University  

DOE Data Explorer

Buried 40 feet beneath Alumni Field on the Cornell University campus is the 768 meter Cornell Electron Storage Ring (CESR). CESR is an electron-positron collider that stores beams accelerated by the Cornell Synchrotron and has been in operation for years. Near 2000, a new program began at CESR, known as CESR-c/CLEO-c. The physics focus shifted from the bottom quark to the lighter charm quark. CLEO-c elucidates the weak physics behind both charm and bottom quark decays by helping to disentangle it from the confounding strong-interaction dynamics. In particular, measurements of D and Ds meson decays to leptonic and semileptonic final states are crucial tests of the Lattice QCD techniques used to compute important heavy quark processes. CLEO also studies the hadronic branching fractions of D and Ds mesons and explores spectroscopy of heavy quarkonia and related states.

Field Study in the Cornell University Science of Earth Systems Program  

NASA Astrophysics Data System (ADS)

Cornell University has granted degrees in the Science of Earth Systems since 2000. The SES program is a multi-college and multi-disciplinary effort to integrate the study of the solid earth, atmosphere, hydrosphere and biosphere. An intensive, experiential component was added to the curriculum in 2001 with the introduction of the first Hawai'i-based field course. In 2004 the winter intersession field class was expanded to a full semester-length field program supporting the SES curriculum. The Earth and Environmental Systems (EES) Field Program on Hawai'i Island is open to well-prepared undergraduate students from any college or university. While it is designed to fulfill requirements in the SES curriculum, students from majors spanning the earth sciences, life sciences and engineering have participated, thus creating a multidisciplinary student body as well as faculty. Instruction is entirely field-based. Students learn from hands-on activities across a variety of topics, including volcanology, watershed hydrology, oceanography, biogeochemistry, and cultural and historical studies. The Big Island of Hawai'i is the world's premier field site for the study of Earth system interactions. The age progression of its five hot spot volcanoes and the island's location within the band of persistent NE trade winds combined with 4000 meters of vertical relief produce a 3-dimensional matrix of dramatic topographic, environmental, and temporal gradients that can be used in a variety of ways to study the effects of environmental change on natural and anthropogenic systems. The intensive nature of field-based learning produces outcomes different from a classroom environment. The students have been removed from their comfort zone and that this does indeed make them uncomfortable. Students must confront new modes of learning, are forced to learn independently, and from each other. The unequivocal result is that the students become more capable and independent learners. Second, the projects that students undertake are embedded in a real-world context, either as part of an ongoing scientific study or as community service. Through this experience students are inspired and empowered by the opportunity to make a real and substantive contribution. They are highly motivated to learn and to achieve, and are very successful. Connecting the curriculum to the community that hosts us has been the most successful aspect of the EES program.

High-flux x-ray undulator radiation from proposed B factory storage rings at Cornell University  

SciTech Connect

Two intersecting storage rings (8 GeV, 1 A and 3.5 GeV, 2 A) have been proposed to be built at Cornell University to enhance both the production of {ital B} mesons and synchrotron radiation. Exceedingly high x-ray flux from 3-m long undulators will be the new feature of a {ital B} factory for the CHESS laboratory. The flux produced integrated over the central cone of radiation can be as much as an order of magnitude higher than from the third-generation storage rings (now under construction) operating at 0.1 A.

Spectroscopy and implosion dynamics of nested wire arrays produced on the 1 MA z-pinch generator at Cornell University  

NASA Astrophysics Data System (ADS)

Experiments with low wire number nested wire arrays from Al, Stainless steel, and combinations of these two materials have been performed on the 1 MA Cobra generator at Cornell University. The diagnostic complex included fast x-ray and EUV detectors, both time-gated and integrated x-ray pinhole cameras, x-ray and EUV spectrometers, and laser probing imaging. Modeling of time-gated spectra indicates that the electron temperature gradually increases with time in the nested wire array experiments that were analyzed, even after the current maximum, whereas the electron density shows more non-monotonic behavior. In addition, for spatially resolved, time integrated spectra from combination arrays, the results of modeling of radiation from outer and inner wires were compared. Modeling of K-shell Fe indicates the highest electron temperature, Te ˜800eV, which was reached with the pure SS304 nested array. This work was supported by NNSA/SSAA under DOE Cooperative Agreement DE-F03-02NA00057, by the NNSA under UNR grant DE-FC52 01NV14050, and by Sandia National Laboratories under DOE contract DE-AC04-94AL85000.

Universal Usability  

NASA Astrophysics Data System (ADS)

Universal usability of World Wide Web (Web) environments—that is, having 90% of households as successful users—requires universal access, usability, and universal design. Factors such as Web technology and user-centered design contribute to universal access and usability, but key to universal usability is a universal design methodology. Universal design principles for the Web follow from universal design principles for the built environment, and emphasize perceptibility, self-explanation, and tailorability for the user. Universally usable Web environments offer the benefit of expanded participation, as well as the unanticipated benefits that generally follow from innovative design initiatives. However, to achieve Web universal usability, Web designers need tools that facilitate the design of intuitive interfaces without sacrificing universal access.

Astronomers have carefully measured the changing positions of stars, leading them to believe that the Sun is located about half-way out from the center of a disk-shaped galaxy of stars, part of which can be seen as a glowing band of light that spans the sky on a very clear night. Although our Sun is a single star, most stars exist in systems of two or more stars orbiting around one another and are arranged in huge star clusters. Galaxies are isolated collections of billions of gravitationally bound stars and immense clouds of gas and dust. Galaxies are, in turn, grouped into galaxy clusters and super-clusters. The universe contains many billions of galaxies separated by immense distances of mostly empty space. Some of these distant galaxies are so far away that their light takes several billion years to reach Earth. This means that here on Earth we are seeing them as they were that long ago. Learning Outcomes:� Arrange various objects in order of size and distance, ranging from space probes and moons to galaxies and galactic clusters.� Catalogue, in simple terms, the objects within a galaxy.� Generally explain "what is within what" (planetary systems, star clusters, galaxies, etc.).� Describe the location of our solar system within the Milky Way galaxy.� Describe the limitations of using parallax, radar, and brightness to measure the distance of objects from Earth, and classify objects whose distance from Earth could be accurately measured using each type of measurement strategy.

Many Universes POSSIBLE!  

NASA Astrophysics Data System (ADS)

An innovative scientific work on the evolution of the universe unravels a fresh phenomenon about the birth and evolution of a Big Bang. We see why Big Bang is not the earliest evolutionary stage of the universe rather it is necessarily just a part of the Universe which couldn't be revered more than a womb for clusters. SYNTESIS: The Big Bang starts from a black hole i.e. prior to Big Bang there was a black hole and there is expected a number of Big Bang in the universe going similar to our Big Bang and the whole process of the expansion and contraction of the Big Bang as described in the paper.

IS THE UNIVERSE ROTATING?  

SciTech Connect

Models of a rotating universe have been studied widely since the work of Goedel, who showed an example that is consistent with general relativity. By now, the possibility of a rotating universe has been discussed comprehensively in the framework of some types of Bianchi's models, such as Type V, VII, and IX and different approaches have been proposed to constrain the rotation. Recent discoveries of some non-Gaussian properties of the Cosmic Microwave Background Anisotropies (CMBA), such as the suppression of the quadrupole and the alignment of some multipoles draw attention to some Bianchi models with rotation. However, cosmological data, such as those of the CMBA, strongly prefer a homogeneous and isotropic model. Therefore, it is of interest to discuss the rotation of the universe as a perturbation of the Robertson-Walker metric, to constrain the rotating speed by cosmological data and to discuss whether it could be the origin of the non-Gaussian properties of the CMBA mentioned above. Here, we derive the general form of the metric (up to second-order perturbations) which is compatible with the rotation perturbation in a flat LAMBDA-CDM universe. By comparing the second-order Sachs-Wolfe effect due to rotation with the CMBA data, we constrain the angular speed of the rotation to be less than 10{sup -9} rad yr{sup -1} at the last scattering surface. This provides the first constraint on the shear-free rotation of a LAMBDACDM universe.

Recognizing that the University Reactor Instrumentation Program was developed in response to widespread needs in the academic community for modernization and improvement of research and training reactors at institutions such as the University of Florida, the items proposed to be supported by this grant over its two year period have been selected as those most likely to reduce foreed outages, to meet regulatory concerns that had been expressed in recent years by Nuclear Regulatory Commission inspectors or to correct other facility problems and limitations. Department of Energy Grant Number DE-FG07-90ER129969 was provided to the University of Florida Training Reactor(UFTR) facility through the US Department of Energy's University Reactor Instrumentation Program. The original proposal submitted in February, 1990 requested support for UFTR facility instrumentation and equipment upgrades for seven items in the amount of $107,530 with $13,800 of this amount to be the subject of cost sharing by the University of Florida and $93,730 requested as support from the Department of Energy. A breakdown of the items requested and total cost for the proposed UFTR facility instrumentation and equipment improvements is presented.

Physics at Fisk University  

NASA Astrophysics Data System (ADS)

Fisk University was started in 1866 for predominantly Black students at the end of the Civil War. Its Department of Physics was started in 1931, under the chairmanship of Dr. Elmer Imes, Fisk '03, a research physicist in the field of infrared spectroscopy. Imes set the stage for Fisk's development of an infrared spectroscopy research laboratory. After Imes' untimely death in 1942, one of his early physics majors, James Lawson, chaired the Fisk Physics Department and soon obtained a research type infrared instrument from the University of Michigan. By the early 50's, five Fisk graduate students in physics published with their faculty mentors, the results of their M.A. degree research in infrared spectroscopy and read papers at the meetings of SESAPS. This active participation in SESAPS of Fisk's Black physicists was the impetus which caused SESAPS in 1954 to switch its meetings from segregated to unsegregated facilities. SESAPS then accepted the invitation of Fisk University to hold its 1955 annual meeting on the Fisk campus. But there is lots more to tell of Physics at Fisk University: research in ion optics and the solid state (like growing crystals in ``zero gravity"); research collaboration with Oak Ridge, Vanderbilt and Bordeaux, France; diversification of the physics student population; the impact of Fisk's physicists on the University's financial ``ups and downs"; etc. We will touch on all this and more!

The Biological Universe  

NASA Astrophysics Data System (ADS)

Throughout the twentieth century, from the furor over Percival Lowell's claim of canals on Mars to the sophisticated Search for Extraterrestrial Intelligence, otherworldly life has often intrigued and occasionally consumed science and the public. The Biological Universe provides a rich and colorful history of the attempts during the twentieth century to answer questions such as whether "biological law" reigns throughout the universe and whether there are other histories, religions, and philosophies outside those on Earth. Covering a broad range of topics, including the search for life in the solar system, the origins of life, UFOs, and aliens in science fiction, Steven J. Dick shows how the concept of extraterrestrial intelligence is a world view of its own, a "biophysical cosmology" that seeks confirmation no less than physical views of the universe. This book will fascinate astronomers, historians of science, biochemists, and science fiction readers.

Baby universe theory.  

NASA Astrophysics Data System (ADS)

The authors give an elementary review of the so called "the theory of baby universes" which is a series of ideas or speculations about some effects in quantum gravity, viz. the effect of a certain type of wormholes, representing the exchange of small 3-space universes called baby universes. They consider this "theory" as being physically and scientifically a very promising candidate for a theory of everything. It is, however, mathematically lacking any strong foundation at all. It solves several fine-tuning problems: First of all the cosmological constant problem, and also the strong CP-problem and the hierarchy problem. The authors also speculate that it might predict the possibility of influencing the probability distributions of the outcome of quantum mechanical measurements at one time by acts at a later time.

The Classification of Universes  

ScienceCinema

We define a universe as the contents of a spacetime box with comoving walls, large enough to contain measurable phenomena, but not much larger. This allows the construction of a local ensemble of such universes, given modest extrapolations of the observed properties of the cosmos. We then assume that further out similar universes can be constructed, but with different standard model parameters, strongly correlated with the size in a definite way, where by size is meant the Hubble scale at late times. This allows an estimate of the range of sizes supporting life as we know it. The result allows some understanding of the hierarchy problems of particle physics. Other possible implications of the assumptions made will be discussed, including a possible connection between the QCD vacuum structure and cosmological horizon structure. In all cases, our approach is as bottoms-up and as phenomenological as possible, suggesting that theories of the multiverse may eventually lay some claim of being scientific.

Universality in network dynamics  

NASA Astrophysics Data System (ADS)

Despite significant advances in characterizing the structural properties of complex networks, a mathematical framework that uncovers the universal properties of the interplay between the topology and the dynamics of complex systems continues to elude us. Here we develop a self-consistent theory of dynamical perturbations in complex systems, allowing us to systematically separate the contribution of the network topology and dynamics. The formalism covers a broad range of steady-state dynamical processes and offers testable predictions regarding the system's response to perturbations and the development of correlations. It predicts several distinct universality classes whose characteristics can be derived directly from the continuum equation governing the system's dynamics and which are validated on several canonical network-based dynamical systems, from biochemical dynamics to epidemic spreading. Finally, we collect experimental data pertaining to social and biological systems, demonstrating that we can accurately uncover their universality class even in the absence of an appropriate continuum theory that governs the system's dynamics.

Universality of geometry  

NASA Astrophysics Data System (ADS)

In models of emergent gravity the metric arises as the expectation value of some collective field. Usually, many different collective fields with appropriate tensor properties are candidates for a metric. Which collective field describes the "physical geometry"? We resolve this "metric ambiguity" by an investigation of the most general form of the quantum effective action for several metrics. In the long-distance limit the physical metric is universal and accounts for a massless graviton. Other degrees of freedom contained in the various metric candidates describe very massive scalars and symmetric second rank tensors. They only play a role at microscopic distances, typically around the Planck length. The universality of geometry at long distances extends to the vierbein and the connection. On the other hand, for distances and time intervals of Planck size geometry looses its universal meaning. Time is born with the big bang.

Visiting the Gödel universe.  

PubMed

Visualization of general relativity illustrates aspects of Einstein's insights into the curved nature of space and time to the expert as well as the layperson. One of the most interesting models which came up with Einstein's theory was developed by Kurt Gödel in 1949. The Gödel universe is a valid solution of Einstein's field equations, making it a possible physical description of our universe. It offers remarkable features like the existence of an optical horizon beyond which time travel is possible. Although we know that our universe is not a Gödel universe, it is interesting to visualize physical aspects of a world model resulting from a theory which is highly confirmed in scientific history. Standard techniques to adopt an egocentric point of view in a relativistic world model have shortcomings with respect to the time needed to render an image as well as difficulties in applying a direct illumination model. In this paper we want to face both issues to reduce the gap between common visualization standards and relativistic visualization. We will introduce two techniques to speed up recalculation of images by means of preprocessing and lookup tables and to increase image quality through a special optimization applicable to the Gödel universe. The first technique allows the physicist to understand the different effects of general relativity faster and better by generating images from existing datasets interactively. By using the intrinsic symmetries of Gödel's spacetime which are expressed by the Killing vector field, we are able to reduce the necessary calculations to simple cases using the second technique. This even makes it feasible to account for a direct illumination model during the rendering process. Although the presented methods are applied to Gödel's universe, they can also be extended to other manifolds, for example light propagation in moving dielectric media. Therefore, other areas of research can benefit from these generic improvements. PMID:18989011

Birth of inflationary universes  

SciTech Connect

A cosmological model is proposed in which the Universe is created by quantum tunneling from ''nothing'' into a de Sitter space. The tunneling is described by a de Sitter-- p Hawking--Moss instanton. After the tunneling, the model evolves along the lines of the inflationary scenario. It is argued that at any time there exist parts of the Universe which are still in the de Sitter phase, while other parts have already recollapsed. This model does not have a big-bang singularity and does not require any initial or boundary conditions.

More than ten years ago, joint Order of the Ministries of Education and Atomic Energy No. 28/33 was signed on January 16, 1991. It was titled "On Providing Staff for Research and Applied Work in Nuclear Physics, Elementary Particle Physics, Condensed Matter Physics, and High-Temperature Superconductivity." This Order initiated the specialized education on the basis of JINR of graduate students from Moscow State University (MSU), Moscow Engineering Physics Institute (MEPI), and, a little later, Moscow Institute of Physics and Technology (MIPT). On the grounds of this Order, the University Centre (the UC) was established, whose 10th anniversary was celebrated on March 21, 2001.

Imaging the early universe  

SciTech Connect

An international team of cosmologists has released the first detailed images of the universe in its infancy. The images reveal the structure that existed when the universe was a tiny fraction of its current age and 1,000 times smaller and hotter than it is today. Research carried out as part of this project is shedding light on some of cosmology's long-standing mysteries, such as the nature of the matter and energy that dominate intergalactic space and whether space is ''curved'' or ''flat.''(c) 2000 Optical Society of America.

Anisotropically inflating universes  

SciTech Connect

We show that in theories of gravity that add quadratic curvature invariants to the Einstein-Hilbert action there exist expanding vacuum cosmologies with positive cosmological constant which do not approach the de Sitter universe. Exact solutions are found which inflate anisotropically. This behavior is driven by the Ricci curvature invariant and has no counterpart in the general-relativistic limit. These examples show that the cosmic no-hair theorem does not hold in these higher-order extensions of general relativity and raises new questions about the ubiquity of inflation in the very early universe and the thermodynamics of gravitational fields.

Child Universe Production  

NASA Astrophysics Data System (ADS)

There are solutions of Israel junction conditions that describe the detachment of a region of spacetime, a bubble, from what can be called the parent spacetime. In the past these solutions have been mostly considered in the context of inflationary cosmology (the so called baby universes). We will i) briefly review these ideas, ii) show that they can be of interest under more general settings and iii) present solutions where it is possible to create a universe at arbitrarily small energy cost. This could have interesting applications for quantum gravity and particle physics, besides cosmology.

Evolution of the Universe  

NASA Astrophysics Data System (ADS)

Cosmology is in the midst of a scientific revolution that is establishing its lasting foundations. The good agreement between many different sorts of observations and the predictions of the now-standard Lambda Cold Dark Matter (LCDM) theory gives us hope that this is humanity's first picture of the history of the universe as a whole that might actually be true. An unexpected feature of this new picture is that we humans appear to be central or special in many ways -- for example, we are made of the rarest stuff in the universe (stardust); we are intermediate in size between the smallest possible size (the Planck length) and the largest size (the cosmic horizon); and we are living at a pivotal time: the period in the history of the universe when its expansion began to accelerate rather than slow down, and in the middle of the ten-billion-year lifetime of our solar system and of the billion year most habitable period of our planet, and at what must be the end of the exponential growth of human impact on the earth. This talk will review key observations that support modern cosmology, describe some symbolic ways of understanding the modern cosmos, and discuss some possible implications of a cosmic perspective for our 21st century worldview. Based on a new book, The View from the Center of the Universe: Discovering Our Extraordinary Place in the Cosmos, by Joel R. Primack and Nancy Ellen Abrams (Riverhead Books, April 2006).

Universal Test Facility  

NASA Astrophysics Data System (ADS)

A universal test facility (UTF) for Space Station Freedom is developed. In this context, universal means that the experimental rack design must be: automated, highly marketable, and able to perform diverse microgravity experiments according to NASA space station requirements. In order to fulfill these broad objectives, the facility's customers, and their respective requirements, are first defined. From these definitions, specific design goals and the scope of the first phase of this project are determined. An examination is first made into what types of research are most likely to make the UTF marketable. Based on our findings, the experiments for which the UTF would most likely be used included: protein crystal growth, hydroponics food growth, gas combustion, gallium arsenide crystal growth, microorganism development, and cell encapsulation. Therefore, the UTF is designed to fulfill all of the major requirements for the experiments listed above. The versatility of the design is achieved by taking advantage of the many overlapping requirements presented by these experiments.

Universal newborn hearing screening  

PubMed Central

The present statement reviews the evidence for universal newborn hearing screening (UNHS). A systematic review of the literature was conducted using Medline and using search dates from 1996 to the third week of August 2009. The following search terms were used: neonatal screening AND hearing loss AND hearing disorders. The key phrase “universal newborn hearing screening” was also searched. The Cochrane Central Register of Controlled Trials and systematic reviews was searched. Three systematic reviews, one controlled non-randomized trial and multiple cohort studies were found. It was determined that there was satisfactory evidence to support UNHS. The results of the available literature are consistent and indicate clear evidence that without UNHS, delayed diagnosis leads to significant harm for children and their families; with UNHS, diagnosis and intervention occur earlier; earlier intervention translates to improved language outcomes; and in well-run programs, there is negligible harm from screening.

The quintessential universe  

NASA Astrophysics Data System (ADS)

Recent evidence suggests that most of the energy in the universe consists of some form of dark energy that is gravitationally self-repulsive and that is causing the expansion rate of the universe to accelerate. We review the evidence, including recent measurements of the cosmic microwave background by the DASI, BOOMerang and MAXIMA groups. The dark energy may consist of vacuum energy density (or, equivalently, a cosmological constant), or quintessence, a time-evolving, spatially inhomogeneous component with negative pressure. A key problem is to explain the initial conditions required to have the energy density nearly coincident with the matter density today. A possible solution is ``k-essence,'' a form of quintessence with an attractor-like solution which leads to cosmic acceleration today for a very wide range of initial conditions without fine-tuning and without invoking an anthropic argument. .

Universality in oscillating flows.  

PubMed

We show that oscillating flow of a simple fluid in both the Newtonian and the non-Newtonian regime can be described by a universal function of a single dimensionless scaling parameter omega tau, where omega is the oscillation (angular) frequency and tau is the fluid relaxation time; geometry and linear dimension bear no effect on the flow. Energy dissipation of mechanical resonators in a rarefied gas follows this universality closely in a broad linear dimension (10(-6) m < L < 10(-2) m) and frequency (10(5) Hz < omega/2pi < 10(8) Hz) range. Our results suggest a deep connection between flows of simple and complex fluids. PMID:19437646

Beyond universal precautions.  

PubMed Central

Universal precautions have gained wide acceptance in the literature and are promoted by major health care regulatory bodies as a measure to prevent nosocomial transmission of bloodborne diseases. Nevertheless, Dr. James G. Wright and associates (see pages 1089 to 1095 of this issue) provide evidence of the infrequent use of universal precautions by surgeons in Toronto. Their findings are consistent with those of similar studies and point to the limitations of any safety approach that relies on the active compliance of individuals rather than on passive, environmental controls. Successful approaches to optimizing workplace safety should first emphasize passive measures for risk abatement, including firm policies, the use of safer equipment and techniques, procedural safeguards and regular monitoring. Routine voluntary screening of patients undergoing procedures that pose a high risk of contamination may improve compliance to safety procedures by health care personnel. Further study is required.

The radioactive universe.  

SciTech Connect

In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the impact of radionactivity on the evolution of the universe. We demonstrate that whether the radion overcloses the universe, constitutes the dark matter, is the inflaton, the curvaton, or does not play any role in cosmology, depends crucially on the ratio between the energy densities stored in the radion and in the inflaton at the time of inflation. We discuss the general difficulties in reconciling models with low compactification scale (i.e., TeV scale) with the simple picture of inflation.

Universal Indicator Rainbow Trout  

NSDL National Science Digital Library

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases. The initial coat of indicator changes the color of the paper (it will turn a salmon color if the paper is acidic, and green if it is considered acid-free). From there, adding acids (such as lemon juice) and bases (such as laundry detergent) will further change the color. Universal indicator responds to a wide range of acids and bases, so other home chemicals (shampoo, vinegar, etc.) could be tried to create different colors. For older learners, a paper pattern other than a "rainbow trout" (such as a rainforest bird or other colorful animal) can be used.

Universal quantum interfaces  

SciTech Connect

To observe or control a quantum system, one must interact with it via an interface. This article exhibits simple universal quantum interfaces--quantum input/output ports consisting of a single two-state system or quantum bit that interacts with the system to be observed or controlled. It is shown that under very general conditions the ability to observe and control the quantum bit on its own implies the ability to observe and control the system itself. The interface can also be used as a quantum communication channel, and multiple quantum systems can be connected by interfaces to become an efficient universal quantum computer. Experimental realizations are proposed, and implications for controllability, observability, and quantum information processing are explored.

The spacetimes corresponding to a weak version of the cosmological principle are considered. It appears that, starting from very different criteria, they were already obtained by Stephani and studied by Krasinski and Barnes. The only barotropic universes of this class are the Friedmann-Robertson-Walker ones. Among the others, some admit a general thermodynamic scheme; it is shown that, as for barotropic fluids, such a scheme also imposes additional symmetries.

The Molecular Universe  

NASA Astrophysics Data System (ADS)

During the last decade it has become more and more clear that the molecular universe is widespread and very diverse. The near and mid IR spectra of the diffuse interstellar medium of the Milky Way and other galaxies is dominated by the vibrational emission of large (50 C-atoms) Polycyclic Aromatic Hydrocarbon molecules. These emission features are also bright in many regions of massive star formation as well as in the ashes expelled by stars in their death throes. These ubiquitous molecules lock up about 1-10 % of all the available elemental carbon. It is now also clear that the Diffuse Interstellar Bands in the visible spectral range - which have presented a spectroscopic enigma since their discovery 75 years ago - are due to electronic transitions of interstellar molecules. Besides these PAHs, likely candidates include acetylenic C-chains and fullerenes. Similarly, spectroscopic studies of the rotational, millimeter and submillimeter spectra of molecular clouds - the birthsites of new stars - have revealed a rich inventory of molecules which increases at a pace of about 5 new molecules a year for the last 25 years. Molecules have now been discovered as far back as z = 4.7 when the first burst of star formation accompanied galaxy formation in the universe. Indeed, cooling by molecules probably played as key a role in star formation at that time as it does in the present universe. In the solar system, the chemical composition of comets still attests to its heritage of the interstellar cloud from which the solar system formed 4.5 billion years ago, while carbonaceous meteorites display a very diverse pattern of organic species including a wide variety of amino acids many of which are unknown in nature on Earth. This talk will review the richness of the molecular universe and the processes that play a role in the origin and evolution of these species.

The horizonless universe  

NASA Astrophysics Data System (ADS)

A closed microuniverse that inflates into a macrouniverse loses its particle horizon. The conditions for this rule to apply are discussed. A particular model illustrates how the particle horizon, which limits the range of causal connections, vanishes permanently into the antipode as a result of inflation. Such a closed universe may display in vestigial form on the scale of superclusters the polytopal structure of the original microuniverse.

Inflation in the universe  

SciTech Connect

The hot big bang cosmology, or the standard cosmology as it is appropriately known, is a highly successful model, providing a reliable and tested accounting of the Universe from 0.01 sec after the bang until today, some 15 Gyr later. However, very special initial data seem to be required in order to account for the observed smoothness and flatness of our Hubble volume and for the existence of the small primeval density inhomogeneities required for the formation of structure in the Universe. Inflation offers a means of accounting for these special initial data, which is based upon physics at sub-planck energy scales (<< m/sub pl/ approx. = 10/sup 19/ GeV) and is motivated by contemporary ideas in particle theory. Here I review the status of the 'Inflationary Paradigm'. At present essentially all inflationary models involve a very weakly-coupled (quantified by the presence of a dimensionless parameter of order 10/sup -12/ or so) scalar field which is displaced from the minimum of its potential. Regions of the Universe where the scalar field is initially displaced from its minimum undergo inflation as the scalar field relaxes, resulting in a Universe today which resembles ours in regions much larger than our present Hubble volume (approx. = 10/sup 28/ cm), but which on very large scales (>> 10/sup 28/ cm) may be highly irregular. The most conspicuous blemish on the paradigm is the lack of a compelling particle physics model to implement it. I also review some other unresolved issues, and discuss in detail the all important confrontation between inflation and observational data. Finally, I discuss the possibility that inflation leads to large-scale, primeval magnetic fields of sufficient strength to be of astrophysical interest. 123 refs., 4 figs.

Cornel West Controversy  

NSDL National Science Digital Library

Harvard University Professor, theologian, and social activist Cornel West may soon be leaving his position at Harvard for Princeton University due to strained relations with Harvard's new president, Lawrence Summers. A primary source of the conflict was West's compact disc released last summer titled 'Sketches of My Culture.' Summers, who arrived on campus in October after serving as Treasury Secretary during the latter days of the Clinton administration, criticized West during one of their private conversations. Discussing the conflict during an interview with Tavis Smily, West characterizes what transpired as "an assault on his integrity." He further states "In my 26 years of teaching this is unprecedented for me... I've never been attacked or insulted in that particular way." After Summers' apology, Harvard spokesperson, Joe Wrinn stated "President Summers and Professor West had a good conversation that cleared the air and ended with a feeling of mutual respect." However, a spokesman for West revealed that West is still considering leaving Harvard but will not make a definite decision until February at the earliest. For now, West is devoting all of his focus and energy on his health. He will soon be facing prostate cancer surgery.

Electrogustometry is a method for taste diagnosis and measurement. The EG-2 project is being developed in cooperation between Warsaw University of Technology and Military institute of Medicine in Warsaw. The device is an evolution of the recent universal electrogustometer EG-1 prototype. Due to considerations and experiences acquired during prototype usage, many enhancements have been incorporated into device. The aim was to create an easy-to-use, portable, battery powered device, enabled for fast measurements. Developed electrogustometer is using innovative, low-power microprocessor system, which control whole device. User interface is based on 5.7" graphical LCD (Liquid Crystal Display) and touchscreen. It can be directly operated by finger or with optional stylus. Dedicated GUI (Graphical User Interface) offers simple, predefined measurements and advance settings of signal parameters. It is also possible to store measurements results and patients data in an internal memory. User interface is multilanguage. Signals for patients examinations, supplied with bipolar electrode, are generated by an on-board circuit using DDS (Direct-Digital Synthesis) and DAC (Digital-to-Analog Converter). Electrogustometer is able to generate DC, sinus, triangle or rectangle signals with current amplitude from 0 to 500 pA and frequency form 0 to 500 Hz. Device is designed for manual and automeasurement modes. By using USB (Universal Serial Bus) port it is possible to retrieve data stored in internal memory and charging of built-in Li-lon battery as a source of power. PMID:21735666

Universally coupled massive gravity  

NASA Astrophysics Data System (ADS)

We derive Einstein’s equations from a linear theory in flat space-time using free-field gauge invariance and universal coupling. The gravitational potential can be either covariant or contravariant and of almost any density weight. We adapt these results to yield universally coupled massive variants of Einstein’s equations, yielding two one-parameter families of distinct theories with spin 2 and spin 0. The Freund-Maheshwari-Schonberg theory is therefore not the unique universally coupled massive generalization of Einstein’s theory, although it is privileged in some respects. The theories we derive are a subset of those found by Ogievetsky and Polubarinov by other means. The question of positive energy, which continues to be discussed, might be addressed numerically in spherical symmetry. We briefly comment on the issue of causality with two observable metrics and the need for gauge freedom and address some criticisms by Padmanabhan of field derivations of Einstein-like equations along the way.

This astronomy program is designed for middle school children in out-of-school-time settings. The program explores basic astronomy concepts (like invisible light, telescopes) and focuses on the universe outside the solar system (stars, galaxies, black holes). By offering programming on these topics outside of the classroom, where schedules are less constrained, Afterschool Universe engages students in science and keeps them interested. Afterschool Universe consists of 12 sessions, each typically requiring 45-60 minutes for implementation. The program is flexibly structured for use in a variety of settings, including astronomy days, summer camps, or year-long afterschool programming. Although sessions build concepts when attended sequentially, each session is intended to be freestanding as not all participants may attend every session. A comprehensive manual provides background information and detailed descriptions of how to conduct each activity. The manual has been written for leaders with little science background. A companion Wweb siteWeb site provides additional information and resources for the program leader. All the activities are done âin the real worldâ and do not require a computer. Suggestions for optional web-based activities are provided for locations with computers or for at-home extensions.

The Universal Ancestor  

NASA Astrophysics Data System (ADS)

A genetic annealing model for the universal ancestor of all extant life is presented; the name of the model derives from its resemblance to physical annealing. The scenario pictured starts when ``genetic temperatures'' were very high, cellular entities (progenotes) were very simple, and information processing systems were inaccurate. Initially, both mutation rate and lateral gene transfer levels were elevated. The latter was pandemic and pervasive to the extent that it, not vertical inheritance, defined the evolutionary dynamic. As increasingly complex and precise biological structures and processes evolved, both the mutation rate and the scope and level of lateral gene transfer, i.e., evolutionary temperature, dropped, and the evolutionary dynamic gradually became that characteristic of modern cells. The various subsystems of the cell ``crystallized,'' i.e., became refractory to lateral gene transfer, at different stages of ``cooling,'' with the translation apparatus probably crystallizing first. Organismal lineages, and so organisms as we know them, did not exist at these early stages. The universal phylogenetic tree, therefore, is not an organismal tree at its base but gradually becomes one as its peripheral branchings emerge. The universal ancestor is not a discrete entity. It is, rather, a diverse community of cells that survives and evolves as a biological unit. This communal ancestor has a physical history but not a genealogical one. Over time, this ancestor refined into a smaller number of increasingly complex cell types with the ancestors of the three primary groupings of organisms arising as a result.

This evidence suggests that the origin of the universe occurred approximately 13.6 billion years ago, during a point in time when the state of the universe was much hotter and more dense. The fact that light seen from almost all distant galaxies has longer wavelengths than comparable light here on earth provides evidence that the whole universe has been expanding ever since the big bang (and continues to expand today). Learning Outcomes:� Provide a basic description of the conditions at the beginning of the universe.� Give the approximate age of the universe.� Recognize the scientific account of the current state of the universe given different explanations.� Explain the evidence for an expanding universe.� Describe, in simple terms, how scientists use observations of position and motion to learn about objects in the universe.

Universality of weak selection  

NASA Astrophysics Data System (ADS)

Weak selection, which means a phenotype is slightly advantageous over another, is an important limiting case in evolutionary biology. Recently, it has been introduced into evolutionary game theory. In evolutionary game dynamics, the probability to be imitated or to reproduce depends on the performance in a game. The influence of the game on the stochastic dynamics in finite populations is governed by the intensity of selection. In many models of both unstructured and structured populations, a key assumption allowing analytical calculations is weak selection, which means that all individuals perform approximately equally well. In the weak selection limit many different microscopic evolutionary models have the same or similar properties. How universal is weak selection for those microscopic evolutionary processes? We answer this question by investigating the fixation probability and the average fixation time not only up to linear but also up to higher orders in selection intensity. We find universal higher order expansions, which allow a rescaling of the selection intensity. With this, we can identify specific models which violate (linear) weak selection results, such as the one-third rule of coordination games in finite but large populations.

Open universe from inflation  

SciTech Connect

We present a natural scenario for obtaining an open universe ({Omega}{sub 0}{lt}1) through inflation. In this scenario, there are two epochs of inflationary expansion---an epoch of ``old inflation,`` during which the inflaton field is stuck in a false vacuum, followed by an epoch of ``new inflation,`` during which the inflation field slowly rolls toward its true minimum. During the first epoch, inflation solves the smoothness and horizon problems. Then an open universe (with negative spatial curvature) is created by the nucleation of a single bubble. In effect {Omega} is instantaneously ``reset`` to zero. During the subsequent ``new`` inflation {Omega} rises toward unity. The value of {Omega} today is calculable in terms of the parameters of the potential, and we show that obtaining values significantly different from zero or unity (though within the range 0{lt}{Omega}{lt}1) does not require significant fine-tuning. We compute the spectrum of density perturbations by evolving the Bunch-Davies vacuum modes across the bubble wall into its interior.

Universality in Bacterial Colonies  

NASA Astrophysics Data System (ADS)

The emergent spatial patterns generated by growing bacterial colonies have been the focus of intense study in physics during the last twenty years. Both experimental and theoretical investigations have made possible a clear qualitative picture of the different structures that such colonies can exhibit, depending on the medium on which they are growing. However, there are relatively few quantitative descriptions of these patterns. In this paper, we use a mechanistically detailed simulation framework to measure the scaling exponents associated with the advancing fronts of bacterial colonies on hard agar substrata, aiming to discern the universality class to which the system belongs. We show that the universal behavior exhibited by the colonies can be much richer than previously reported, and we propose the possibility of up to four different sub-phases within the medium-to-high nutrient concentration regime. We hypothesize that the quenched disorder that characterizes one of these sub-phases is an emergent property of the growth and division of bacteria competing for limited space and nutrients.

Physics in Universe's Youth  

NASA Astrophysics Data System (ADS)

Using a quasar located 12.3 billion light-years away as a beacon, a team of astronomers detected the presence of molecular hydrogen in the farthest system ever, an otherwise invisible galaxy that we observe when the Universe was less than 1.5 billion years old, that is, about 10% of its present age. The astronomers find that there is about one hydrogen molecule for 250 hydrogen atoms. A similar set of observations for two other quasars, together with the most precise laboratory measurements, allows scientists to infer that the ratio of the proton to electron masses may have changed with time. If confirmed, this would have important consequences on our understanding of physics. "Detecting molecular hydrogen and measuring its properties in the most remote parts of the Universe is important to understand the gas environment and determine the rate of star formation in the early Universe", said Cédric Ledoux, lead-author of the paper presenting the results [1]. Although molecular hydrogen is the most abundant molecule in the Universe, it is very difficult to detect directly. For the time being, the only way to detect it directly in the far Universe is to search for its telltale signatures in the spectra of quasars or gamma-ray burst afterglows. This requires high spectral resolution and large telescopes to reach the necessary precision. A team of astronomers, comprised of Cédric Ledoux (ESO), Patrick Petitjean (IAP, Paris, France) and Raghunathan Srianand (IUCAA, Pune, India), is conducting a survey for molecular hydrogen at high redshift using the Ultraviolet and Visible Echelle Spectrograph (UVES) at ESO's Very Large Telescope. Out of the 75 systems observed up to now, 14 have firm detection of molecular hydrogen. Among these, one is found having a redshift of 4.224. While using the 12.3 billion light-years distant quasar PSS J 1443+2724 as a beacon, the astronomers detected several features belonging to an unseen galaxy having a redshift of 4.224. In particular, many lines from molecular hydrogen were found, breaking the record for the detection of this element in the farthest object in the Universe. This also implies that the gas in this galaxy must be rather cold, about -90 to -180 degrees Celsius. ESO PR Photo 1r/06 Molecular Hydrogen in Distant Galaxy In addition, several lines from 'metals' are also seen, allowing the researchers to deduce the amount of various chemical elements. "From the abundance of Nitrogen observed, we argue that it had to be produced in the late stage of the life of 4 to 8 solar mass stars," said Patrick Petitjean. "Thus, star-formation activity must have formed at least 200 to 500 million years before we are observing the galaxy, that is, when the Universe was about one billion years old" [2]. If the galaxy went through a phase of intense star-formation activity, it is now, at the time of the observations, in a rather quiescent state. "These observations demonstrate the possibility to perform these studies at the highest redshift with ESO's VLT", said Raghunathan Srianand. "In particular, the possibility to observe the interstellar medium of distant galaxies revealed by using gamma-ray bursts as beacons will boost this field in the near future." [3] A similar set of accurate measurements of molecular hydrogen lines was made by the astronomers [4] with UVES on the VLT towards two others quasars, Q 0405-443 and Q 0347-383. This set of data allowed the scientists to compare the ratio of the mass of a proton to that of an electron in molecular hydrogen as it is now and how it was about 12 billion years ago [5]. To this aim, they performed extremely accurate measurements of spectral lines of hydrogen molecules in the laboratory and compared the results with the same lines observed in the spectra of these quasars. These measurements show that the mass ratio of the proton and the electron may have changed, becoming 0.002% smaller in the past twelve billion years. Albeit such a change may look tiny, it would have important consequences on our understa

Plasma and the universe  

SciTech Connect

Hannes Alfven has enjoyed a long and spectacular career in which he has time and again pioneered the path that other workers were able fruitfully to exploit. One thinks of the Alven waves, the concept of gyrocenter drift and the perturbation theory based on it, and the critical velocity phenomenon in the interaction of a plasma with a neutral gas. All of these discoveries have been of fundamental importance. By no means content to rest on his laurels, Alfven has, during the last decade, contributed to science in a major sense, especially in the field of cosmogeny. For example, he has used the latest data from the Voyager spacecraft to test his detailed predictions of the structure of the Saturnian rings. Alfven's current preoccupation is with the Plasma Universe and, as may be expected, some of his concepts are receiving observational support, while others are still controversial.

Self-Accelerated Universe  

NASA Astrophysics Data System (ADS)

It is widely believed that the large redshifts for distant supernovae are due to the vacuum energy dominance, which is responsible for the anti-gravitation effect. A tacit assumption is that particles move along geodesics for the background metric. This is in the same spirit as the consensus regarding the uniform Galilean motion of a free electron. However, apart from the Galilean solution, there is a self-accelerated solution to the Lorentz-Dirac equation governing the behavior of a radiating electron. Likewise, a runaway solution to the entire system of equations, both gravitation and matter equations of motion including, may exist, which provides an alternative explanation for the accelerated expansion of the Universe.

Universal Landau pole.  

PubMed

Our understanding of quantum gravity suggests that at the Planck scale the usual geometry loses its meaning. If so, the quest for grand unification in a large non-Abelian group naturally endowed with the property of asymptotic freedom may also lose its motivation. Instead, we propose a unification of all fundamental interactions at the Planck scale in the form of a universal Landau pole, at which all gauge couplings diverge. The Higgs quartic coupling also diverges while the Yukawa couplings vanish. The unification is achieved with the addition of fermions with vector gauge couplings coming in multiplets and with hypercharges identical to those of the standard model. The presence of these particles also prevents the Higgs quartic coupling from becoming negative, thus avoiding the instability (or metastability) of the standard model vacuum. PMID:23862991

Brane Universe: Global Geometry  

SciTech Connect

The global geometries of bulk vacuum space-times in the brane-universe models are investigated and classified in terms of geometrical invariants. The corresponding Carter-Penrose diagrams and embedding diagrams are constructed. It is shown that for a given energy-momentum induced on the brane there can be different types of global geometries depending on the signs of a bulk cosmological term and surface energy density of the brane (the sign of the latter does not influence the internal cosmological evolution). It is shown that in the Randall-Sundrum scenario it is possible to have an asymmetric hierarchy splitting even with a Z{sub 2}-symmetric matching of 'our' brane to the bulk.

Some toy sheet universes  

NASA Astrophysics Data System (ADS)

Our model is based on the model studied by Langer [1] and in more detail by Langer and Žofka [2]. In these papers we studied a toy closed universe which is flat except of a thin spherical shell. The model was constructed in the framework of the Israel formalism [3]. In this approach the history of a thin shell of matter is described by the time-like hypersurface ? which divides the spacetime into two parts V- and V+. The hypersuface ? is a common boundary of V- and V+ consequently its intrinsic metric induced by the geometries in both regions must be the same. However, the extrinsic curvatures of ? in V- and V+ are in general different. The jump in projections of the extrinsic curvature tensors on ? determines the surface energy-momentum tensor of matter on ?.

Fred Hoyle's Universe  

NASA Astrophysics Data System (ADS)

Fred Hoyle was a Yorkshire truant who became the voice of British astronomy. For fifty years, he spoke out for astronomy in the newspapers, on government committees, at scientific meetings, in popular books and on the radio. He devised a never-ending history of the universe, and worked out how the elements were made. He founded a prestigious institute for theoretical astronomy and built a giant telescope, and if it rained on his summer holiday, he sat in his caravan and wrote science fiction novels for his legions of fans around the world. Fred Hoyle also claimed that diseases fall from the sky, that the big bang never happened, and that the Astronomer Royal should be abolished. When the outspoken Fred Hoyle spoke out for astronomy, some astronomers really wished he had kept his mouth shut. This book tells the behind-the-scenes story of Hoyle's widely acclaimed and deeply controversial role in the ideas, organization and public face of astronomy in post-war Britain. It chronicles the triumphs, acrimony, jealousies, rewards and bitter feuds of a field in turmoil, and meets the astronomers, contemplating cosmic questions, keeping secrets, losing their tempers, winkling information out of distant stars and, over tea on the lawn, discussing the finer points of libel law. Fred Hoyle's Universe draws on previously confidential government documents, recently released personal correspondence and interviews with Hoyle's friends, colleagues and critics, as well as with Hoyle himself, to bring you the man, the science, and the scandal behind the genial and genteel facade of the most exciting period in the history of astronomy.

Acceleration of Black Hole Universe  

NASA Astrophysics Data System (ADS)

An alternative cosmological model called black hole universe has been recently proposed by the author. According to this model, the universe originated from a hot star-like black hole, and gradually grew up through a supermassive black hole to the present state by accreting ambient materials and merging with other black holes. The entire space is structured with an infinite number of layers hierarchically. The innermost three layers are the universe that we live, the outside space called mother universe, and the inside star-like and supermassive black holes called child universes. The outermost layer has an infinite radius and limits to zero for both the mass density and absolute temperature. All layers or universes are governed by the same physics, the Einstein general theory of relativity with the Robertson-Walker metric of space-time, and tend to expand outward physically. The evolution of the space structure is iterative. When one universe expands out, a new similar universe grows up from its inside. In this study. we will analyze the acceleration of black hole universe that accretes its ambient matter in an increasing rate. We will also compare the result obtained from the black hole universe model with the measurement of type Ia supernova and the result from the big bang cosmology.

Quantization of Bianchi type universe  

NASA Astrophysics Data System (ADS)

In this paper we have used the square root formulation of the Wheeler-De Witt equation to quantize a minisuperspace consisting of the Bianchi Type-I universe and a source of radiation field. We have derived a wavefunction of the universe with a conserved current and a positive-definite probability density. We have also explored the quantization of Bianchi Type-III universe using a procedure similar to that used in the ordinary quantum theory in curved spacetime. We have given the wavefunction satisfied by the Wheeler-De Witt equation. Regarding the wavefunction as an operator in a minisuperspace we have not only avoided the difficulty of probabilistic interpretation in quantum cosmology, but also obtained the conclusion of multiple production of universe. We have estimated the mean numbers of various types of universes generated from nothing and shown the distribution of the generated universes to be Planckian.

Universal mechatronics coordinator  

NASA Astrophysics Data System (ADS)

Mechatronic systems incorporate multiple actuators and sensor which must be properly coordinated to achieve the desired system functionality. Many mechatronic systems are designed as one-of-a-kind custom projects without consideration for facilitating future system or alterations and extensions to the current syste. Thus, subsequent changes to the system are slow, different, and costly. It has become apparent that manufacturing processes, and thus the mechatronics which embody them, need to be agile in order to more quickly and easily respond to changing customer demands or market pressures. To achieve agility, both the hardware and software of the system need to be designed such that the creation of new system and the alteration and extension of current system is fast and easy. This paper describes the design of a Universal Mechatronics Coordinator (UMC) which facilitates agile setup and changeover of coordination software for mechatronic systems. The UMC is capable of sequencing continuous and discrete actions that are programmed as stimulus-response pairs, as state machines, or a combination of the two. It facilitates the modular, reusable programing of continuous actions such as servo control algorithms, data collection code, and safety checking routines; and discrete actions such as reporting achieved states, and turning on/off binary devices. The UMC has been applied to the control of a z- theta assembly robot for the Minifactory project and is applicable to a spectrum of widely differing mechatronic systems.

Hydrogen fuel - Universal energy  

NASA Astrophysics Data System (ADS)

The technology for the production, storage, transmission, and consumption of hydrogen as a fuel is surveyed, with the physical and chemical properties of hydrogen examined as they affect its use as a fuel. Sources of hydrogen production are described including synthesis from coal or natural gas, biomass conversion, thermochemical decomposition of water, and electrolysis of water, of these only electrolysis is considered economicially and technologically feasible in the near future. Methods of production of the large quantities of electricity required for the electrolysis of sea water are explored: fossil fuels, hydroelectric plants, nuclear fission, solar energy, wind power, geothermal energy, tidal power, wave motion, electrochemical concentration cells, and finally ocean thermal energy conversion (OTEC). The wind power and OTEC are considered in detail as the most feasible approaches. Techniques for transmission (by railcar or pipeline), storage (as liquid in underwater or underground tanks, as granular metal hydride, or as cryogenic liquid), and consumption (in fuel cells in conventional power plants, for home usage, for industrial furnaces, and for cars and aircraft) are analyzed. The safety problems of hydrogen as a universal fuel are discussed, noting that they are no greater than those for conventional fuels.

Viscous dark fluid universe  

SciTech Connect

We investigate the cosmological perturbation dynamics for a universe consisting of pressureless baryonic matter and a viscous fluid, the latter representing a unified model of the dark sector. In the homogeneous and isotropic background the total energy density of this mixture behaves as a generalized Chaplygin gas. The perturbations of this energy density are intrinsically nonadiabatic and source relative entropy perturbations. The resulting baryonic matter power spectrum is shown to be compatible with the 2dFGRS and SDSS (DR7) data. A joint statistical analysis, using also Hubble-function and supernovae Ia data, shows that, different from other studies, there exists a maximum in the probability distribution for a negative present value q{sub 0{approx_equal}}-0.53 of the deceleration parameter. Moreover, while previous descriptions on the basis of generalized Chaplygin-gas models were incompatible with the matter power-spectrum data since they required a much too large amount of pressureless matter, the unified model presented here favors a matter content that is of the order of the baryonic matter abundance suggested by big-bang nucleosynthesis.

Baryogenesis in the Early Universe  

SciTech Connect

The Universe we observe is baryon-antibaryon asymmetric. There is a negligible amount of primordial antimatter. The presented theoretical scenarios provide a possible mechanism of baryogenesis which could have taken place in the Early Universe, and which may explain the observed asymmetry.

Quantum entanglement of baby universes  

SciTech Connect

We study quantum entanglements of baby universes which appear in non-perturbative corrections to the OSV formula for the entropy of extremal black holes in type IIA string theory compactified on the local Calabi-Yau manifold defined as a rank 2 vector bundle over an arbitrary genus G Riemann surface. This generalizes the result for G=1 in hep-th/0504221. Non-perturbative terms can be organized into a sum over contributions from baby universes, and the total wave-function is their coherent superposition in the third quantized Hilbert space. We find that half of the universes preserve one set of supercharges while the other half preserve a different set, making the total universe stable but non-BPS. The parent universe generates baby universes by brane/anti-brane pair creation, and baby universes are correlated by conservation of non-normalizable D-brane charges under the process. There are no other source of entanglement of baby universes, and all possible states are superposed with the equal weight.

The age of universe  

NASA Astrophysics Data System (ADS)

The presence of short-lived isotope Curium-247 in the early Solar System complicates the job of dating the earliest events in the solar nebula. Primitive components in meteorites contain a detailed record of the conditions and processes in the solarnebula, the cloud of dust and gas surrounding the infant Sun. Determining accurately when the first materialsformed re-quires the lead-lead (Pb-Pb) dating method, a method based on the decay of uranium (U) isotopes toPb isotopes. The initial ratio of U-238 to U-235 is critical to determining theages correctly, and many studies have concluded that the ratio is constant for any given age. How-ever, my colleagues at Arizona State University(Frankfurt, Germany), and the Senckenberg Forschungsinstitut und Naturmuseum (also in Frankfurt) and I have found that some calcium-aluminum-rich inclusions (CAIs) in chondritic meteorites deviate from the conventional value for the U-238/U-235 ratio. This could lead to inaccuracies of up to 5 million years in the age of these objects, if no correction is made.Variations in the concentrations of thorium and neodymium with the U-238/U-235 ratio suggest that the ratio may have been lowered by the decay of curium-247, which decays to U-235 with a half-life of 15.6 million years. Curium-247 is created in certain types of energetic supernovae, so its presence suggests that a supernova added material to the pre-solar interstellar cloud between 110 and 140 million years before theSolar System began to form.

The Universe: An Introduction  

NSDL National Science Digital Library

Astronomy is a science that asks fundamental questions about the very fundament of things, the universe. How big and how far away are the planets and stars? How did they form and when? How do they move and why? Finding answers to those questions has been the highest adventure of the human mind, and yet the questions, in essence, are those of any child looking into the sky. The lessons in this issue of Smithsonian in Your Classroom address the questions, therefore, by first asking the students.In Lesson 1, the class works together to arrange pictures from space according to the studentsâ best ideas of size, distance, and age. This active introduction to the cosmos can be a pre-assessment for a unit on space science. Lesson 2 is a modeling exercise in which relationships in space are brought down to a scale of two inches. Both lessons are based on educational materials created by the Smithsonian Astrophysical Observatory, in cooperation with NASA. All images needed for the lessons can be downloaded from this page.The issue also includes a profile of Smithsonian astronomer Lisa Kaltenegger, who is in the burgeoning business of âÂÂplanet huntingâÂÂâÂÂthe discovery of planets outside of our solar system. The first âÂÂexoplanetâ was discovered in 1995. There have been hundreds of discoveries since. The work is bringing closer to the fore a question in the back of anyoneâÂÂs mind when looking at the sky: Is anyone else out there?

[Universal electrogustometer EG-1].  

PubMed

Electrogustometry has been used as a clinical tool for diagnosis and assessment of a variety of conditions. Since the lack of versatile electrogustometer for research and diagnosis, the new electrogustometer EG-1 was developed in 2006. It was done in cooperation between Warsaw University of Technology and Military Institute of Medicine in Warsaw. EG-1 allows quantitative estimation of taste perception threshold using both static and impulse electrogustometry with bipolar electrode. It is a fully autonomous, battery powered and portable instrument. Because of small size and weight, it can be easily placed in any environment. Microprocessor controlled measurement system and user-friendly interface (LCD display with simple keyboard) make EG-1 electrogustometer very handy and flexible in operation. Data obtained during measurements is stored in the internal device memory. After taste examinations measurement data can be transferred to a personal computer via inbuilt USB port for further analysis and storage. EG-1 can generate three predefined variously shaped current impulses: sinus-, saw- and rectangle-shaped. There is an optional possibility of creating own shapes of stimulus puls by the user. The electrical parameters of generated pulses are as follow: current amplitude 1-2000 microA regulated with 1 microA step, stimulus frequency 0(DC)-500 Hz regulated with 5 Hz step, controlable fulfillment factor and signal rise time (optional for automatic measurements). The operator can trigger the stimuli via a hand switch on the bipolar electrode (with gold-plated endings), via keyboard or via additional independent hand switch. Three years of experience collected during EG-1 exploitation allowed to design a new version of electrogustometer EG-2 with a touch panel and color graphical display. PMID:19886533

Entropy of viscous Universe models  

NASA Astrophysics Data System (ADS)

The cosmological event horizon entropy and the apparent horizon entropy of the ?CDM and the Bianchi type I Universe model with viscosity has been calculated numerically, and analytically in the large time limit. It is shown that for these Universe models the cosmological event horizon entropy increases with time and for large times it approaches a finite maximum value. The effect of viscosity upon the entropy is also studied and we have found that its role is to decrease the entropy. The bigger the viscosity coefficient is the less the entropy will be. Furthermore, the radiation entropy for the ?CDM Universe model with and without viscosity is investigated, and together with the cosmological event horizon entropy are used to examine the validity of the generalized second law of thermodynamics, which states that the total rate of change of entropy of the Universe is never negative, in this Universe model.

Acceleration of black hole universe  

NASA Astrophysics Data System (ADS)

Recently, Zhang slightly modified the standard big bang theory and developed a new cosmological model called black hole universe, which is consistent with Mach's principle, governed by Einstein's general theory of relativity, and able to explain all observations of the universe. Previous studies accounted for the origin, structure, evolution, expansion, and cosmic microwave background radiation of the black hole universe, which grew from a star-like black hole with several solar masses through a supermassive black hole with billions of solar masses to the present state with hundred billion-trillions of solar masses by accreting ambient matter and merging with other black holes. This paper investigates acceleration of the black hole universe and provides an alternative explanation for the redshift and luminosity distance measurements of type Ia supernovae. The results indicate that the black hole universe accelerates its expansion when it accretes the ambient matter in an increasing rate. In other words, i.e., when the second-order derivative of the mass of the black hole universe with respect to the time is positive ddot{M}(t) > 0. For a constant deceleration parameter q = -M(t) ddot{M}(t)/dot{M}(t) ˜-0.6, we can perfectly explain the type Ia supernova measurements with the reduced chi-square to be very close to unity, ? red˜1.0012. The expansion and acceleration of black hole universe are driven by external energy.

The relic cosmic background neutrinos accompanying the cosmic microwave background (CMB) photons may hide a universal lepton asymmetry orders of magnitude larger than the universal baryon asymmetry. At present, the only direct way to probe such an asymmetry is through its effect on the abundances of the light elements produced during primordial nucleosynthesis. The relic light element abundances also depend on the baryon asymmetry, parameterized by the baryon density parameter (\\eta_{\\mathrm {B}} \\equiv n_{\\mathrm {B}}/n_{\\gamma } ) and on the early-universe expansion rate, parameterized by the expansion rate factor (S \\equiv H'/H ) or, equivalently, by the effective number of neutrinos (N_{\

Universality of hypercubic random surfaces  

NASA Astrophysics Data System (ADS)

We study universality properties of the Weingarten hyper-cubic random surfaces. Since a long time the model of hypercubic random surfaces with a local restriction forbidding surface self-bendings was thought to be in a different universality class from the unrestricted model defined on the full set of surfaces. In this paper we show that both models in fact belong to the same universality class with the entropy exponent ? = 1/(2) and differ by the finite size effects which are much more pronounced in the restricted model.

Computational Capacity of the Universe  

NASA Astrophysics Data System (ADS)

All physical systems register and process information. The laws of physics determine the amount of information that a physical system can register (number of bits) and the number of elementary logic operations that a system can perform (number of ops). The Universe is a physical system. The amount of information that the Universe can register and the number of elementary operations that it can have performed over its history are calculated. The Universe can have performed 10120 ops on 1090 bits ( 10120 bits including gravitational degrees of freedom).

Complexity, universality and intermediate degrees  

NASA Astrophysics Data System (ADS)

This paper is a philosophical account of complexity versus universality. It seems sustainable to equate universal systems to complex systems or at least to potentially complex systems. Post's problem on the existence of (natural) intermediate degrees (between decidable and universal ?01) then finds its analog in the Principle of Computional Equivalence (PCE). In this abstract we address possible driving forces -if any- behind PCE. Both the natural aspects as well as the cognitive ones are investigated. We postulate a principle GNS that we call the Generalized Natural Selection principle that together with the Church-Turing thesis is seen to be equivalent in a sense to a weak version of PCE.

Universal planetary tectonics (supertectonics)  

NASA Astrophysics Data System (ADS)

Universal planetary tectonics (supertectonics) G. Kochemasov IGEM of the Russian Academy of Sciences, Moscow, Russia, kochem.36@mail.ru The wave planetology [1-3 & others] proceeds from the following: "planetary structures are made by orbits and rotations". A uniform reason makes uniform structures. Inertia-gravity waves arising in planetary bodies due to their movements in Keplerian elliptical orbits with periodically changing accelerations warp these bodies in such way that they acquire polyhedron shapes (after interference of standing waves of four directions). Strong Newtonian gravity makes bodies larger than ~400 to 500 km in diameter globular and polyhedra are rarely seen. Only geomorphologic, geologic and geophysical mapping can develop these hidden structures. But small bodies, normally less than ~ 300 to 400 km in diameter, often show parts of the polyhedra, rarely fully developed forms (the asteroid Steins and satellite Amalthea present rather perfect forms of "diamond"). Depending on warping wavelengths (they make harmonics) various Plato's figures superimposed on each other can be distinguished. The fundamental wave 1 produces a tetrahedron, intrinsically dichotomic figure in which a vertex (contraction) always is opposed to a face (expansion). From the recent examples the best is the saturnian northern hexagon (a face) opposed to the southern hurricane (a vertex). The first overtone wave 2 is responsible for creation of structural octahedra. Whole ‘diamonds" and their parts are known [4, 5]. Other overtones produce less developed (because of smaller wave amplitudes) planetary shapes complicating main forms. Thus, the first common structural peculiarity of planetary bodies is their polyhedron nature. Not less important is the second common structural peculiarity. As all globular or smaller more or less isometric bodies rotate, they have an angular momentum. It is inevitably different in tropic and extra-tropic belts having uneven radii or distances to the rotation axe. But this unevenness is undesirable because it creates tectonic stresses and increases energetic status that is against the natural tendency to minimize these physical characteristics. So, a body tends to lower angular momentum of tropics and increase it in extra-tropics. With the same angular velocity it remains only mass and radius to play in this tendency. Tropical belt is destructed (for an example, the lithosphere disintegration in solid bodies), extra-tropical belts add dense material (plumes), expand - the constructive tendency [6]. Both tectonic peculiarities-polyhedrons and constructive - destructive tendencies - are common for celestial bodies of various classes. They are characteristic for our star, planets, satellites and small bodies. That is why a term "supertectonics" seems rather suitable. References: [1] Kochemasov G.G.

Neutrinos in the early universe

The neutrinos from the Big Bang or the Cosmic Neutrino Background (CNB) carry precious information from the early epoch when our universe was only 1 s old. Although not yet directly detected, CNB may be revealed indirectly through cosmological observations due to neutrino important cosmological influence.We review the cosmological role of neutrinos and the cosmological constraints on neutrino characteristics. Namely, we discuss the impact of neutrinos in the early universe: the cosmic expansion, neutrino decoupling, the role of neutrinos in the primordial production of light elements, leptogenesis, etc. We briefly discuss the role of neutrino at later stages of the universe.Due to the considerable cosmological influence of neutrinos, cosmological bounds on neutrino properties from observational data exist. We review the cosmological constraints on the effective number of neutrino species, neutrino mass and mixing parameters, lepton number of the universe, presence of sterile neutrino, etc.

A Universe without Weak Interactions  

SciTech Connect

A universe without weak interactions is constructed that undergoes big-bang nucleosynthesis, matter domination, structure formation, and star formation. The stars in this universe are able to burn for billions of years, synthesize elements up to iron, and undergo supernova explosions, dispersing heavy elements into the interstellar medium. These definitive claims are supported by a detailed analysis where this hypothetical ''Weakless Universe'' is matched to our Universe by simultaneously adjusting Standard Model and cosmological parameters. For instance, chemistry and nuclear physics are essentially unchanged. The apparent habitability of the Weakless Universe suggests that the anthropic principle does not determine the scale of electroweak breaking, or even require that it be smaller than the Planck scale, so long as technically natural parameters may be suitably adjusted. Whether the multi-parameter adjustment is realized or probable is dependent on the ultraviolet completion, such as the string landscape. Considering a similar analysis for the cosmological constant, however, we argue that no adjustments of other parameters are able to allow the cosmological constant to raise up even remotely close to the Planck scale while obtaining macroscopic structure. The fine-tuning problems associated with the electroweak breaking scale and the cosmological constant therefore appear to be qualitatively different from the perspective of obtaining a habitable universe.

A universe without weak interactions  

SciTech Connect

A universe without weak interactions is constructed that undergoes big-bang nucleosynthesis, matter domination, structure formation, and star formation. The stars in this universe are able to burn for billions of years, synthesize elements up to iron, and undergo supernova explosions, dispersing heavy elements into the interstellar medium. These definitive claims are supported by a detailed analysis where this hypothetical ''weakless universe'' is matched to our Universe by simultaneously adjusting standard model and cosmological parameters. For instance, chemistry and nuclear physics are essentially unchanged. The apparent habitability of the weakless universe suggests that the anthropic principle does not determine the scale of electroweak breaking, or even require that it be smaller than the Planck scale, so long as technically natural parameters may be suitably adjusted. Whether the multiparameter adjustment is realized or probable is dependent on the ultraviolet completion, such as the string landscape. Considering a similar analysis for the cosmological constant, however, we argue that no adjustments of other parameters are able to allow the cosmological constant to raise up even remotely close to the Planck scale while obtaining macroscopic structure.

Universal particle flux pressure converter  

US Patent & Trademark Office Database

The design of Shaded Rotor devices to demonstrate the existence of a hypothetical Universal Particle Flux Field is presented. These devices should extract a measurable amount of energy from this Field. We believe the Universal Particle Flux Field can explain all invisible forces at a distance phenomena between masses, charged bodies, and magnetic materials. We propose that the Universal Particle Flux Field is a simultaneously convergent/divergent field, where the particle streams traverse to any point in the Universe from every other point in the Universe. The order of this Flux Field is a nearly perfect disorder, which is an order in itself. The strength of the gravitational component of this Field is conventionally denoted by "G". Two neutral masses immersed in such Flux Field will develop forces between them, which are consistent with Newton's Equation of Gravitation. This Field is also consistent with Electrostatic, and Magnetic Force Equations. A magnetic rotor is preferentially shaded with a magnetic stator so that a net torque exists on the rotor. This principle is also applied to an electrostaticly charged Shaded Rotor device. The possibilities that the Beta, the Muon, and the Tau Neutrinos are the Universal Particles and they are producing the Electrostatic, Magnetic, and Gravitational Force Fields respectively, are explored. Laboratory sized Shaded Rotor Devices can be constructed using magnetic and/or electrostatic components; detailed designs are described herein. Circumstantial evidences described herein, indicate that the Universal Gravitational Constant "G" hence the "g" of the Earth is direction and time variable, and it has significantly increased during the last several hundred million years; this may account for the demise of the Dinosaurs, and of the giant vegetation.

Traveling in the Computational Universe  

NASA Astrophysics Data System (ADS)

The concept of travel, specifically ``space travel'', cannot be separated from the concept of ``Universe'', because the Universe is where space and time acquire their significance, along with their properties, possibilities and limitations. Mankind is strongly focused on a four dimensional Universe, with its Lorentzian or Euclidean interpretation. It is still a puzzle about the fact that the four dimensional Universe seems to have a beginning, therefore there seem to be boundaries in space-time and we would like to know the nature of those boundaries and its endpoints. To better understand the deep significance of our best physical theories it could be interesting to compare our Universe with its models. It may happen that the differences between the model and reality can be made indistinguishable, to the point that it may seem acceptable to consider reality as a gigantic program, a ``mother computation'' running in a Universal Computer. The computational interpretation of reality is here adopted for introducing concepts that are common in computer science, they may offer a new insight. For instance, code and memory usage optimization techniques are common in computer science because they improve the performances at a reduced hardware cost. According to the concepts discussed in this paper, the possibility of recognizing the effects of optimization rules in a physical reality will allow us to discriminate if our reality is fundamental or the result of a large computation. Conversely, code and memory optimization has side effects, if it is present in our Universe it can produce many interesting phenomena, some seem readily recognizable, others only wait to be discovered. The science of Space Travel appears suitable for the experimental test of these conceptualizations.

Interdimensional universality of dynamic interfaces.  

PubMed

Despite the complexity and diversity of nature, there exists universality in the form of critical scaling laws among various dissimilar systems and processes such as stock markets, earthquakes, crackling noise, lung inflation and vortices in superconductors. This universality is mainly independent of the microscopic details, depending only on the symmetry and dimension of the system. Exploring how universality is affected by the system dimensions is an important unresolved problem. Here we demonstrate experimentally that universality persists even at a dimensionality crossover in ferromagnetic nanowires. As the wire width decreases, the magnetic domain wall dynamics changes from elastic creep in two dimensions to a particle-like stochastic behaviour in one dimension. Applying finite-size scaling, we find that all our experimental data in one and two dimensions (including the crossover regime) collapse onto a single curve, signalling universality at the criticality transition. The crossover to the one-dimensional regime occurs at a few hundred nanometres, corresponding to the integration scale for modern nanodevices. PMID:19360082

Tuning universality far from equilibrium.  

PubMed

Possible universal dynamics of a many-body system far from thermal equilibrium are explored. A focus is set on meta-stable non-thermal states exhibiting critical properties such as self-similarity and independence of the details of how the respective state has been reached. It is proposed that universal dynamics far from equilibrium can be tuned to exhibit a dynamical transition where these critical properties change qualitatively. This is demonstrated for the case of a superfluid two-component Bose gas exhibiting different types of long-lived but non-thermal critical order. Scaling exponents controlled by the ratio of experimentally tuneable coupling parameters offer themselves as natural smoking guns. The results shed light on the wealth of universal phenomena expected to exist in the far-from-equilibrium realm. PMID:23928853

Big questions about the universe  

NASA Astrophysics Data System (ADS)

Astronomy is not only a branch of science but also an important part of the culture and civilisations of peoples. Starting with archeoastronomy to the present day, it has always contributed to a better understanding of life, of humanity. After 400 years of modern astronomy, it still addresses major problems such as: Why there is something rather than nothing? Why is nature comprehensible to humans? How is cosmos related to humanity? Do multiverses exist? Is there life on other planets? Are we alone in the universe? Does the universe have a beginning? If so, what does it mean? How did the universe originate? All these questions are a challenge for interdisciplinary and transdisciplinary investigations, for philosophers, physicists, cosmologists, mathematicians, theologians. The new insights gained by pursuing in depth these common investigations will shape the society we live in and have important consequences on the future we are creating.

Dark matter in the universe  

NASA Astrophysics Data System (ADS)

What is the quantity and composition of material in the Universe? This is one of the most fundamental questions we can ask about the Universe, and its answer bears on a number of important issues including the formation of structure in the Universe, and the ultimate fate and the earliest history of the Universe. Moreover, answering this question could lead to the discovery of new particles, as well as shedding light on the nature of the fundamental interactions. At present, only a partial answer is at hand. Most of the radiation in the Universe does not give off detectable radiation; it is dark. The dark matter associated with bright galaxies contributes somewhere between 10 and 30 percent of the critical density; baryonic matter contributes between 1.1 and 12 percent of the critical. The case for the spatially flat, Einstein-de Sitter model is supported by three compelling theoretical arguments - structure formation, the temporal Copernican principle, and inflation - and by some observational data. If Omega is indeed unity, or even just significantly greater than 0.1, then there is a strong case for a Universe comprised of nonbaryonic matter. There are three well motivated particle dark matter candidates: an axion of mass 10 -6 eV to 10 -4 eV; a neutrino of mass 10 GeV to about 3 TeV; or a neutrino of mass 20 eV to 90 eV. All three possibilities can be tested by experiments that are either planned or are underway.

Universe Awareness For Young Children  

NASA Astrophysics Data System (ADS)

Universe Awareness (UNAWE) is an international programme that will expose economically disadvantaged young children aged between 4 and 10 years to the inspirational aspects of modern astronomy. The programme is motivated by the premise that access to simple knowledge about the Universe is a basic birth right of everybody. These formative ages are crucial in the development of a human value system. This is also the age range in which children can learn to develop a 'feeling' for the vastness of the Universe. Exposing young children to such material is likely to broaden their minds and stimulate their world-view. The goals of Universe Awareness are in accordance with two of the United Nations Millennium goals, endorsed by all 191 UN member states, namely (i) the achievement of universal primary education and (ii) the promotion of gender equality in schools. We propose to commence Universe Awareness with a pilot project that will target disadvantaged regions in about 4 European countries (possibly Spain, France, Germany and The Netherlands) and several non-EU countries (possibly Chile, Colombia, India, Tunisia, South Africa and Venezuela). There will be two distinct elements in the development of the UNAWE program: (i) Creation and production of suitable UNAWE material and delivery techniques, (ii) Training of educators who will coordinate UNAWE in each of the target countries. In addition to the programme, an international network of astronomy outreach will be organised. We present the first results of a pilot project developed in Venezuela, where 670 children from different social environments, their teachers and members of an indigenous tribe called Ye´kuana from the Amazon region took part in a wonderful astronomical and cultural exchange that is now being promoted by the Venezuelan ministry of Education at the national level.

Geometry for the accelerating universe  

SciTech Connect

The Lorentzian spacetime metric is refined to an area metric which naturally emerges as a generalized geometry in quantum string and gauge theory. Employing the area metric curvature scalar, the Einstein-Hilbert gravitational action is reinterpreted as dynamics for an area metric. The area metric cosmology of the radiation-dominated early universe does not depart from general relativity, enabling successful nucleosynthesis. But intriguingly, without the need for dark energy or fine-tuning, area metric cosmology explains the observed small acceleration of the late universe.

Can the universe afford inflation?  

SciTech Connect

Cosmic inflation is envisioned as the 'most likely' start for the observed universe. To give substance to this claim, a framework is needed in which inflation can compete with other scenarios and the relative likelihood of all scenarios can be quantified. The most concrete scheme to date for performing such a comparison shows inflation to be strongly disfavored. We analyze the source of this failure for inflation and present an alternative calculation, based on more traditional semiclassical methods, that results in inflation being exponentially favored. We argue that reconciling the two contrasting approaches presents interesting fundamental challenges, and is likely to have a major impact on ideas about the early universe.

Initial conditions for bubble universes  

SciTech Connect

The ''bubble universes'' of Coleman and De Luccia play a crucial role in string cosmology. Since our own Universe is supposed to be of this kind, bubble cosmology should supply definite answers to the long-standing questions regarding cosmological initial conditions. In particular, it must explain how an initial singularity is avoided, and also how the initial conditions for inflation were established. I argue that the simplest nonanthropic approach to these problems involves a requirement that the spatial sections defined by distinguished bubble observers should not be allowed to have arbitrarily small volumes. Casimir energy is a popular candidate for a quantum effect which can ensure this, but (because it violates energy conditions) there is a danger that it could lead to nonperturbative instabilities in string theory. I make a simple proposal for the initial conditions of a bubble universe, and show that my proposal ensures that the system is nonperturbatively stable. Thus, low-entropy conditions can be established at the beginning of a bubble universe without violating the second law of thermodynamics and without leading to instability in string theory. These conditions are inherited from the ambient spacetime.

Oscillating universe in massive gravity  

NASA Astrophysics Data System (ADS)

Massive gravity is a modified theory of general relativity. In this paper, we study, using a method in which the scale factor changes as a particle in a “potential,” all possible cosmic evolutions in a ghost-free massive gravity. We find that there exists, in certain circumstances, an oscillating universe or a bouncing one. If the universe starts at the oscillating region, it may undergo a number of oscillations before it quantum mechanically tunnels to the bounce point and then expands forever. But going back to the singularity from the oscillating region is physically not allowed. So, the big bang singularity can be successfully resolved. At the same time, we also find that there exists a stable Einstein static state in some cases. However, the universe cannot stay at this stable state past eternally since it is allowed to quantum mechanically tunnel to a big-bang-to-big-crunch region and end with a big crunch. Thus, a stable Einstein static state universe cannot be used to avoid the big bang singularity in massive gravity.
