Simultaneous invention and the patent law

DEFF Research Database (Denmark)

Howells, John

inventions they often find this to challenge the idea that patent law (which rewards only the first inventor with exclusive rights) is needed to encourage invention and innovation. We review the empirical evidence alleged to show that simultaneous invention is prevalent for important inventions. In general...... is typical of important pioneer inventions in both survey evidence and alleged illustrative cases of simultaneous invention. We show this in the cases of Edison, the Wright brothers, the Selden automobile patent vis a vis Ford, Watt and the steam engine. We then point out that patent law inherently ensures...... that patent protection is not extended to near simultaneous inventions. There remain a number of simultaneous inventions discovered through interference proceedings but we find the number too small to mount a serious challenge to the general operation of patent law....

countries of the world. From the point of view of the purpose and objectives of the research, we have used the parametrical model with the allocation and assessment of such parameters, methods and indicators, which provide the integrated assessment of the dynamics of inventive and patent productivity and effectiveness allowing to reach the high level of reliability. The authors have applied the following methods: dialectic and gnoseological one, structural and logical one, structurally functional one, the method of decomposition, the method of statistical groups and index method. A transition from the traditional analysis with parameters and indicators of the high aggregated level to the level of their expedient specification has been carried out. The authors have introduced the specified new key indicators grouped by the criteria: inventive activity; patent activity and effectiveness. The article proves the rationale for a dialectic combination of the process oriented estimates, efficiency evaluations and vector (reflecting development trends estimates. The results of this research can be considered in the case of the development of management decisions by the relevant structures, which are responsible for scientific and technological, and innovation policy at all levels of the power and management.

The mathematician's mind the psychology of invention in the mathematical field

CERN Document Server

Hadamard, Jacques

1996-01-01

Fifty years ago when Jacques Hadamard set out to explore how mathematicians invent new ideas, he considered the creative experiences of some of the greatest thinkers of his generation, such as George Polya, Claude Lévi-Strauss, and Albert Einstein. It appeared that inspiration could strike anytime, particularly after an individual had worked hard on a problem for days and then turned attention to another activity. In exploring this phenomenon, Hadamard produced one of the most famous and cogent cases for the existence of unconscious mental processes in mathematical invention and other forms of creativity. Written before the explosion of research in computers and cognitive science, his book, originally titled The Psychology of Invention in the Mathematical Field, remains an important tool for exploring the increasingly complex problem of mental life. The roots of creativity for Hadamard lie not in consciousness, but in the long unconscious work of incubation, and in the unconscious aesthetic selection of ide...

Original Inventions based on Chemical scaffolds and electro-physical activity-derived biosimilars interacting with specialties in biology yielding platforms for analysis in virology and antiviral compounds

Full Text Available Background: Original inventions in developing countries, in terms of number of patents filed, granted and that are taken to useful applications as well as in terms of publications of high impact remain relatively lower [1,2] compared to that of developed nations. The reasons could be attributed to lack of importance given to basic research in funding, the number of institutes involved, limited technical support or expertise available etc [1]. Though such initiatives may take a long time to yield fruits, one of the parallel steps we considered worth was to take the original inventions from Japan, born out of basic research in one field, taken through an application-oriented inter disciplinary interactive research in healthcare, thereby paving way for novel solutions. Thus was conceived, the Inventions- Inter-Disciplinary Interactions and Solutions (IIDIAS, an academic session as a part of the one-day International stem cell meet organized every year in the month of October by Nichi-In Centre for Regenerative Medicine (NCRM, an academic Institute based in Chennai, India. In the IIDIAS session, based on original invention(s presented as a prelude in brief, original interdisciplinary interactive research work based on the original invention by NCRM and/or its collaborators are presented by the faculty of the relevant institute. That will be followed by an interactive session in which the potential solutions based on the above accomplishments would be discussed. The IIDIAS session 2014 was based on the following two inventions: A bio-film-based biosimilar invented by an electro-physicist A unique polymer invented by a chemical engineer Inventions and Interdisciplinary Interactions: Invention –I: The bio-film-based biosimilar invented by an electro-physicist: An electro physicist with the Kyoto University, Japan, Dr Nobuyuki Yamaji observed during his experiments that plants and mammalian tissues secrete a layer of fluid after getting hit by

Full Text Available At the end of Persiles’ Book IV, Cervantes discovers identity and origin of the heroes, who have been known till then as Periandro and Auristela. According with this intention, the invention of a Nordic place, as Tile —Hero’s hometown—, has a special importance, because of its Vergilian roots on Thule’s imaginary, which appears in Georgics, I, vv. 29-31. A Vergil’s quotation, which is used by Serafido, when he explains what and where Tile is, gives us the evidence. Our purpose is studying the Cervantine reelaboration of such quotation and its aesthetic function in the romance.

The glial cells of the cerebellum, and particularly astrocytes and oligodendrocytes, are characterized by a remarkable phenotypic variety, in which highly peculiar morphological features are associated with specific functional features, unique among the glial cells of the entire CNS. Here, we provide a critical report about the present knowledge of the development of cerebellar glia, including lineage relationships between cerebellar neurons, astrocytes and oligodendrocytes, the origins and the genesis of the repertoire of glial types, and the processes underlying their acquisition of mature morphological and functional traits. In parallel, we describe and discuss some fundamental roles played by specific categories of glial cells during cerebellar development. In particular, we propose that Bergmann glia exerts a crucial scaffolding activity that, together with the organizing function of Purkinje cells, is necessary to achieve the normal pattern of foliation and layering of the cerebellar cortex. Moreover, we discuss some of the functional tasks of cerebellar astrocytes and oligodendrocytes that are distinctive of cerebellar glia throughout the CNS. Notably, we report about the regulation of synaptic signalling in the molecular and granular layer mediated by Bergmann glia and parenchymal astrocytes, and the functional interaction between oligodendrocyte precursor cells and neurons. On the whole, this review provides an extensive overview of the available literature and some novel insights about the origin and differentiation of the variety of cerebellar glial cells and their function in the developing and mature cerebellum.

1987-01-01

This report is an evaluation of the Energy-Related Inventions Program (ERIP). It assess the program's effectiveness and impacts, characterizes participating inventions and inventors, and identifies correlates of successful commercialization in order to suggest possible improvements. Seventy of the 204 ERIP inventions that were studied were successfully introduced into the market, accounting for more than$200M in sales from 1976 through 1984. During 1984, 921 full-time equivalent employees were supported directly by ERIP inventors or their licensees. (Estimates of indirect economic impacts are also contained in the report.) Data on patterns of fund raising clearly show a need for assistance by programs like ERIP. Commercially successful inventors shared several traits. They had less formal education, fewer patents, more work experience in small firms, more outside funding early in their work, more shared responsibility with others for invention development, more management experience, and greater previous experience with starting new businesses. Recommendations are made regarding: (1) priorities for allocating ERIP grants; (2) improved efficiency of the NBS/DOE operations; (3) delivery of technical and commercialization assistance to grant recipients; and (4) further evaluation research

Multiple, connective intellection: the condition for invention

Directory of Open Access Journals (Sweden)

C S (Fanie de Beer

2015-11-01

Full Text Available Since this article involves invention, the conditions for inventiveness become the issue: assuming multiple reality; thinking in a special way; transgressing boundaries; acknowledging networks (in the terms of Michel Serres: communication, transduction, interference, distribution, passages between the sciences. There are, however, misplaced expectations: technology should work wonders in this regard while forgetting that humans, redefined though, remain the key to establish connections and networks between people, paradigms, disciplines, sciences and technologies. Against this background, Michel Serres’s emphasis on invention and “thinking as invention” and his a-critical anti-method – ‘connective, multiple intellection’ which is a special kind of thought – are desperately needed. Guattari’s articulation of the three ecologies and the ecosophic views he developed in this regard provides a significant amplification of the approach of ‘multiple connective intellection’. These insights can be enlightened and strongly driven home through the views of Latour with an anthropological and socio-dynamic perspective on the scientific endeavour with the articulation of the actor-network theory inherited from Serres. The thoughtful beyond-methodology of Edgar Morin with his strong noological position as the ultimate condition for inventiveness, and Gregory Ulmer with his special emphasis on invention and inventiveness, especially with the help and assistance of electronic means (video and internet, and with his work with the architect Bernard Tschumi on invention and inventiveness, are of special significance in the sphere of inventiveness, the real and final guarantee for a spirited re-enchantment of the world as well as the final demonstration that the battle for intelligence as opposed to ignorance, stupidity and barbarism can be fought with great hope to succeed.

The invention of graphene electronics and the physics of epitaxial graphene on silicon carbide

International Nuclear Information System (INIS)

De Heer, Walt A

2012-01-01

Graphene electronics was officially invented at the Georgia Institute of Technology in 2003 after experimental and theoretical research on graphene properties starting from 2001. This paper focuses on the motivation and events leading to the invention of graphene electronics, as well as on recent developments. Graphene electronics was originally conceived as a new electronics paradigm to incorporate the room-temperature ballistic and coherent properties of carbon nanotubes in a patternable electronic material. Graphene on silicon carbide was chosen as the most suitable material. Other electronics schemes, involving transferred (exfoliated and chemical vapor deposition-produced) graphitic materials, that operate in the diffusive regime may not be competitive with standard methods and may therefore not significantly impact electronics. In recent years, epitaxial graphene has improved to the point where graphene electronics according to the original concept appears to be within reach. Beyond electronics, epitaxial graphene research has led to important developments in graphene physics in general and has become a leading platform for graphene science as well.

Ghosts of inventions: Patent law's digital mediations.

Science.gov (United States)

Kang, Hyo Yoon

2018-04-01

This article examines the shifts in the material ordering of inventions in patent law organization and their effects on the meaning and scope of inventions as intellectual property. Formats and media are constitutive of the establishment and stabilization of inventions as objects of intellectual property. Modern patent law's materiality had been dominated by paper documents but ever more consists of digital images, files, and networked data. The article traces and analyzes such effects of digital media on the meaning of intellectual/intangible property and argues that inventions increasingly matter as digital data in the legal realm.

Drug Delivery Research: The Invention Cycle.

Science.gov (United States)

Park, Kinam

2016-07-05

Controlled drug delivery systems have been successful in introducing improved formulations for better use of existing drugs and novel delivery of biologicals. The initial success of producing many oral products and some injectable depot formulations, however, reached a plateau, and the progress over the past three decades has been slow. This is likely due to the difficulties of formulating hydrophilic, high molecular weight drugs, such as proteins and nucleic acids, for targeting specific cells, month-long sustained delivery, and pulsatile release. Since the approaches that have served well for delivery of small molecules are not applicable to large molecules, it is time to develop new methods for biologicals. The process of developing future drug delivery systems, termed as the invention cycle, is proposed, and it starts with clearly defining the problems for developing certain formulations. Once the problems are well-defined, creative imagination examines all potential options and selects the best answer and alternatives. Then, innovation takes over to generate unique solutions for developing new formulations that resolve the previously identified problems. Ultimately, the new delivery systems will have to go through a translational process to produce the final formulations for clinical use. The invention cycle also emphasizes examining the reasons for success of certain formulations, not just the reasons for failure of many systems. Implementation of the new invention cycle requires new mechanisms of funding the younger generation of scientists and a new way of identifying their achievements, thereby releasing them from the burden of short-termism.

THE VALUE AND ECONOMIC EFFECTS OF UNAPPLIED INVENTIONS

Directory of Open Access Journals (Sweden)

Raul Sorin V. FÂNTÂNĂ

2014-06-01

Full Text Available The accounting regulations, the guidelines for their application and other articles by accounting specialists argue that inventions created internally are not recognized as intangible assets. Only assets acquired separately can be measured reliably, based on the document justifying the purchase transaction. Other specialised papers show that it is difficult to establish the existence of this intangible asset and its credible cost. That is, it can give or calculate a value of the invention only if it can show the acceptable cost of achieving it. But all these works argue that the protection of inventions is profitable if it is the basis of a new business, if it promotes or protects the current activity. However, these papers elude - because it is uncomfortable - the situation where an invention created internally has a value only because it forecloses the market. It is curious that an invention has accounting value only when traded.

Ancient engineers' inventions precursors of the present

CERN Document Server

Rossi, Cesare

2017-01-01

This book describes the inventions and designs of ancient engineers who are the precursors of the present. The period ranges mainly from 300 B.C. to 1600 A.D. with several exceptions. Many of the oldest inventions are documented by archaeological finds, often very little known, mainly from Pompeii, Herculaneum and Stabiae and reveal a surprising modernity in their conception. Most of the inventions presented in the first four parts of the book were conceived up to the late Roman Empire and may be considered as milestones, each in their respective field. The fifth part concentrates on more recent centuries. The sixth part deals with some building construction techniques. Generally, for each of the presented inventions, three elements of research and reference are provided: written documents (the classics), iconic references (coins, bas-reliefs, etc.) and archaeological findings. The authors did not write this book for engineers only; hence they describe all the devices without assuming wide technical knowledge...

Humanisme : inventer l'avenir

Mayor, Federico

2014-06-01

Humanism: inventing the future - Humanity is still confronted by the scourges of poverty, hunger, violence and inequality. If we are to invent a better future, we must first understand the past, recalling the missed opportunities of 1918, 1945 and 1989, at the end of two world wars and a cold war. This article summarises the proposals put forward by the author on several occasions during his career. He expresses a forceful confidence in humankind's ability to take control of its destiny and shake off government that puts economic interest before universal human values. The twenty-first century should be the era of rebellion in cyberspace, one in which more women and young people are involved in decision making, heralding a future of freedom and happiness for all.

Examining the social and scientific roles of invention in science education

Science.gov (United States)

Calabrese-Barton, Angela

1998-03-01

I have been drawn to the construct of “invention” and “inventive acts” because in my research involving how homeless children construct science and the self-in-science, an overwhelming theme has been the multiple ways in which self-identity in science has been described by the children through a language of invention. Using post-modern feminism and science and technologies studies, I examine the multiple uses and definitions of “invention” in science in order to develop a theory of invention and inventive acts around the themes: invention as a social act, invention as a recursive and socially linked process, and embodied agency. I use this framework to examine the construct of “invention” in two different case studies involving the science education of urban homeless children. Finally, I link this discussion of invention and inventive acts with current international reform initiatives revolving around constructivist science teaching and learning.

Origins of Protein Functions in Cells

Science.gov (United States)

Seelig, Burchard; Pohorille, Andrzej

2011-01-01

In modern organisms proteins perform a majority of cellular functions, such as chemical catalysis, energy transduction and transport of material across cell walls. Although great strides have been made towards understanding protein evolution, a meaningful extrapolation from contemporary proteins to their earliest ancestors is virtually impossible. In an alternative approach, the origin of water-soluble proteins was probed through the synthesis and in vitro evolution of very large libraries of random amino acid sequences. In combination with computer modeling and simulations, these experiments allow us to address a number of fundamental questions about the origins of proteins. Can functionality emerge from random sequences of proteins? How did the initial repertoire of functional proteins diversify to facilitate new functions? Did this diversification proceed primarily through drawing novel functionalities from random sequences or through evolution of already existing proto-enzymes? Did protein evolution start from a pool of proteins defined by a frozen accident and other collections of proteins could start a different evolutionary pathway? Although we do not have definitive answers to these questions yet, important clues have been uncovered. In one example (Keefe and Szostak, 2001), novel ATP binding proteins were identified that appear to be unrelated in both sequence and structure to any known ATP binding proteins. One of these proteins was subsequently redesigned computationally to bind GTP through introducing several mutations that introduce targeted structural changes to the protein, improve its binding to guanine and prevent water from accessing the active center. This study facilitates further investigations of individual evolutionary steps that lead to a change of function in primordial proteins. In a second study (Seelig and Szostak, 2007), novel enzymes were generated that can join two pieces of RNA in a reaction for which no natural enzymes are known

2018-01-01

Full Text Available Requirements applied to specialists for working in the sixth wave of innovation, i.e. Industry 4.0, determines the necessity of education system improvement concerning training solution and, as a result, creation of inventive ideas. Today in our country this process is stimulated by various competitions, including financing for the implementation of results. In training programs knowledge approach still prevails. The corresponding methods, along with stimulation, are included into educational programs in leading foreign educational institutions, mostly at universities. If in previous decades mostly divergent methods were studied (morphological analysis, the focal objects method, synectics, etc., then now the leading place is taken by theory of inventive problem solving – TRIZ created in the former USSR by G.S. Altshuller in connection with the increasing leading corporations requirement for specialists in TRIZ. This fact gives Russia essential competitive advantages in the innovative way of development. For effective use of this advantage it is important to form the TRIZ-based innovative thinking beginning from school days. For this purpose authors developed new methods in TRIZ-pedagogics, uniting metasubject results (in higher education institutions – competences into the system of innovative thinking. As a result, both educational and economic effects are achieved: the intellectual property created in educational process. For schools it is the possibility of significant improvement of financing causing importance of new mechanisms of intellectual property fixation, protection and implementation. Recommendations about creation of such system are provided in the article. Purpose Defining the opportunities and ways of improving economic effectiveness of educational activities in the paradigm of inventive education.

Perceptions of the Invention Disclosure Process at a Federal Laboratory after the America Invents Act of 2011

Science.gov (United States)

Rice-Moore, Sharla V.

The America Invents Act of 2011 reformed the patent process in the United States. This study focused on the effect of one provision which allows the first inventor to file the application of patent to become the owner of the intellectual property. Prior to this, the Patent and Trademark Act of 1980 allowed small businesses, universities, and non-profit institutions to pursue ownership of intellectual property developed from federally funded research. The new regulations could influence government employees' disclosure of invention and new technology. There is limited research on the disclosure of technology process for government employees. This study examined 1,389 invention disclosure forms from March 2009 to March 2015 during three phases of the law: before it was signed, before the implementation of the first inventor to file provision in 2013, and after full enactment. The reported State of Development showed significant changes prior to implementation for large companies. The findings reveal disclosures were filed at an earlier stage of development, but no change was noted in the significance of the technology. A survey was also distributed using the framework of Organizational Justice theory. The results showed the disclosure reporting process was fair and unbiased. The research supports the efforts of management to keep employees informed about the disclosure process and the importance of technology transfer of government developed innovation. Key words: America Invents Act, Organizational Justice, patent process.

Science, technology and inventions: Children draw their own visions

Science.gov (United States)

D'Addezio, G.; Rubbia, G.; Marsili, A.

2013-12-01

Italian primary schools participated with enthusiasm to the drawing competition 'I'm a scientist too! Science and scientists from the children point of view' organized by the Laboratorio di Didattica e Divulgazione Scientifica of Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Rome, Italy. The best drawings were awarded and published in the 2011 school calendar. Children were asked to realize a drawing, choosing among three suggestions: 1) How do you imagine a scientist, and how do you imagine the daily activities of a researcher? 2) What invention do you consider the most important among all those you know? 3) What would you invent? The topic 'invention' (#3) was the most successful. In fact, among the collected 1,000 drawings, 400 drawings depict scientists, nearly 150 depict scientists with their inventions, and other 350 depict inventions alone. A classification scheme was designed in order to synthetically describe this set of images and analyze it. The Draw-A-Scientist scheme, known from literature, was maintained but modified in order to characterize both inventors and inventions. A preliminary analysis about scientists reveals a persistent gender stereotype, since most of depicted persons were male and nearly half of girls draw men scientists. The image of 'mad scientist' is still present but it is mainly related to men. Women scientists are drawn by girls; they are represented as young, not crazy, usually good-looking. There are no particular differences between boys and girls in assigning research fields to scientists. Women scientists are often depicted as assistants, but when alone they are self-confident enough to give their name to an invention or to aspire for Nobel Prize. In this work we present the preliminary analysis performed on drawings containing inventions. What do girls and boys 6 to 11 years old invent? Robots, helping in housekeeping or in doing homework; rockets, space vehicles and time machines, but also fictional machines and

Malaysian Ministry of Education highlighted in their National Higher Education Strategic plan that higher education’s need to focus adopting 21st century skills in order to increase a graduate’s employability. Current research indicates that most graduate lack of problem solving skills to help them securing the job. Realising the important of this skill hence an alternative way suggested as an option for high institution’s student to solve their problem. This study was undertaken to measure the level of problem solving skills, identify the needs of learning inventive problem solving skills and the needs of developing an Inventive problem solving module. Using a questionnaire, the study sampled 132 students from Faculty of Technical and Vocational Education. Findings indicated that majority of the students fail to define what is an inventive problem and the root cause of a problem. They also unable to state the objectives and goal thus fail to solve the problem. As a result, the students agreed on the developing Inventive Problem Solving Module to assist them.

Rapid, global demographic expansions after the origins of agriculture.

Science.gov (United States)

Gignoux, Christopher R; Henn, Brenna M; Mountain, Joanna L

2011-04-12

The invention of agriculture is widely assumed to have driven recent human population growth. However, direct genetic evidence for population growth after independent agricultural origins has been elusive. We estimated population sizes through time from a set of globally distributed whole mitochondrial genomes, after separating lineages associated with agricultural populations from those associated with hunter-gatherers. The coalescent-based analysis revealed strong evidence for distinct demographic expansions in Europe, southeastern Asia, and sub-Saharan Africa within the past 10,000 y. Estimates of the timing of population growth based on genetic data correspond neatly to dates for the initial origins of agriculture derived from archaeological evidence. Comparisons of rates of population growth through time reveal that the invention of agriculture facilitated a fivefold increase in population growth relative to more ancient expansions of hunter-gatherers.

Bringing functions together with fusion enzymes--from nature's inventions to biotechnological applications.

Science.gov (United States)

Elleuche, Skander

2015-02-01

It is a mammoth task to develop a modular protein toolbox enabling the production of posttranslational organized multifunctional enzymes that catalyze reactions in complex pathways. However, nature has always guided scientists to mimic evolutionary inventions in the laboratory and, nowadays, versatile methods have been established to experimentally connect enzymatic activities with multiple advantages. Among the oldest known natural examples is the linkage of two or more juxtaposed proteins catalyzing consecutive, non-consecutive, or opposing reactions by a native peptide bond. There are multiple reasons for the artificial construction of such fusion enzymes including improved catalytic activities, enabled substrate channelling by proximity of biocatalysts, higher stabilities, and cheaper production processes. To produce fused proteins, it is either possible to genetically fuse coding open reading frames or to connect proteins in a posttranslational process. Molecular biology techniques that have been established for the production of end-to-end or insertional fusions include overlap extension polymerase chain reaction, cloning, and recombination approaches. Depending on their flexibility and applicability, these methods offer various advantages to produce fusion genes in high throughput, different orientations, and including linker sequences to maximize the flexibility and performance of fusion partners. In this review, practical techniques to fuse genes are highlighted, enzymatic parameters to choose adequate enzymes for fusion approaches are summarized, and examples with biotechnological relevance are presented including a focus on plant biomass-degrading glycosyl hydrolases.

Origination and immigration drive latitudinal gradients in marine functional diversity.

Directory of Open Access Journals (Sweden)

Sarah K Berke

Full Text Available Global patterns in the functional attributes of organisms are critical to understanding biodiversity trends and predicting biotic responses to environmental change. In the first global marine analysis, we find a strong decrease in functional richness, but a strong increase in functional evenness, with increasing latitude using intertidal-to-outer-shelf bivalves as a model system (N = 5571 species. These patterns appear to be driven by the interplay between variation in origination rates among functional groups, and latitudinal patterns in origination and range expansion, as documented by the rich fossil record of the group. The data suggest that (i accumulation of taxa in spatial bins and functional categories has not impeded continued diversification in the tropics, and (ii extinctions will influence ecosystem function differentially across latitudes.

Context-dependent memory traces in the crab's mushroom bodies: Functional support for a common origin of high-order memory centers.

Science.gov (United States)

Maza, Francisco Javier; Sztarker, Julieta; Shkedy, Avishag; Peszano, Valeria Natacha; Locatelli, Fernando Federico; Delorenzi, Alejandro

2016-12-06

The hypothesis of a common origin for the high-order memory centers in bilateral animals is based on the evidence that several key features, including gene expression and neuronal network patterns, are shared across several phyla. Central to this hypothesis is the assumption that the arthropods' higher order neuropils of the forebrain [the mushroom bodies (MBs) of insects and the hemiellipsoid bodies (HBs) of crustaceans] are homologous structures. However, even though involvement in memory processes has been repeatedly demonstrated for the MBs, direct proof of such a role in HBs is lacking. Here, through neuroanatomical and immunohistochemical analysis, we identified, in the crab Neohelice granulata, HBs that resemble the calyxless MBs found in several insects. Using in vivo calcium imaging, we revealed training-dependent changes in neuronal responses of vertical and medial lobes of the HBs. These changes were stimulus-specific, and, like in the hippocampus and MBs, the changes reflected the context attribute of the memory trace, which has been envisioned as an essential feature for the HBs. The present study constitutes functional evidence in favor of a role for the HBs in memory processes, and provides key physiological evidence supporting a common origin of the arthropods' high-order memory centers.

Invention and Transfer of Climate Change Mitigation Technologies on a Global Scale: A Study Drawing on Patent Data

International Nuclear Information System (INIS)

Dechezlepretre, A.; Glachant, M.; Hascic, I.; Johnstone, N.; Meniere, Y.

2010-01-01

This paper uses the EPO/OECD World Patent Statistical Database (PATSTAT) to provide a quantitative description of the geographic distribution of inventions in thirteen climate mitigation technologies since 1978 and their international diffusion on a global scale. Statistics suggest that innovation has mostly been driven by energy prices until 1990. Since then, environmental policies, and climate policies more recently, have accelerated the pace of innovation. Innovation is highly concentrated in three countries - Japan, Germany and the USA - which account for 60% of total innovations. Surprisingly, the innovation performance of emerging economies is far from being negligible as China and South Korea together represent about 15% of total inventions. However, they export much less inventions than industrialized countries, suggesting their inventions have less value. More generally, international transfers mostly occur between developed countries (73% of exported inventions). Exports from developed countries to emerging economies are still limited (22%) but are growing rapidly, especially to China. (authors)

In practice, the evaluation was expected to address at least the following aspects of the promotion: The role of the public sector; The role of the private sector (inventors, financiers, companies); The evaluation of the Finnish Foundation for Inventions (FFI); The strengths and weaknesses of the present system for promoting inventions and their commercialisation. In effect, the evaluation proved to be the evaluation of a subsystem integrated within the overall Finnish National System of Innovation with its many players from the public and private sectors. An effort was made to evaluate the relationship between the different actors in this system and closer cooperation is recommended in many areas. Interviews were held with 130 individuals from 70 organisations. The evaluators address the following nine issues: (1) Improving the balance between r and d and the promotion of inventiveness/innovation; (2) Increased coherence between the different organisations; (3) The responsibility of inventors and research organisations in inventive activities and the role of support organisations; (4) A gradual shift towards private services; (5) The development of the role of FFI; (6) Improving the competence in the area of intellectual property rights; (7) Financial incentives for inventors; (8) Increasing the awareness on invention and innovation; (9) The requirement to broaden the concept of inventiveness and innovation.

In spite the instinct social&financial impact of Leg Length Discrepancy (LLD), controversial and conflicting results still exist regarding a reliable assessment/correction method. For proper management it's essential to discriminate between anatomical&functional Leg Length Discrepancy (FLLD). With the newly invented NPoS (New Postural Solution), under the umbrella of the collaboration of PRM Department, Tor Vergata University with Baro Postural Instruments srl, positive results were observed in both measuring& compensating the hemi-pelvic antero-medial rotation in FLLD through personalized bilateral heel raise using two NPoS components: Foot Image System (FIS) and Postural Optimizer System (POS). This led our research interest to test the validity of NPoS as a preliminary step before evaluating its implementations in postural disorders. After clinical evaluation, 4 subjects with FLLD have been assessed by NPoS. Over a period of 2 months, every subject was evaluated 12 times by two different operators, 48 measurements in total, results have been verified in correlation to BTS GaitLab results. Intra-Operator&inter-operator variability analysis showed statistically insignificant differences, while inter-method variability between NPoS and BTS parameters expressed a linear correlation. Results suggest a significant validity of NPoS in assessment&correction of FLLD, with high degree of reproducibility with minimal operator dependency. This can be considered a base for promising clinical implications of NPoS as a reliable cost effective postural assessment/corrective tool. V.

This report provides information on the recent commercial progress of inventions supported by the US Department of Energy's Energy-Related Inventions Programs (ERIP). It describes the results of the latest in a series of ERIP evaluation projects that have been completed since 1980. It focuses on the economic impacts of the program, notably sales and employment benefits. The period of interest is 1980 through 1990. The evaluation is based on data collected through mail and telephone surveying of 143 participants in the Program. As of October 1989, a total of 486 inventions were recommended to DOE by the National Institute for Standards and Technology, which screens all submitted inventions in terms of technical merit, potential for commercial success, and potential energy impact. By the end of 1990, at least 109 of these inventions had entered the market, generating total cumulative sales of more than $500 million. With $25.7 million in grants awarded from 1975 through 1990, and $63.1 million in program appropriations over the same period, ERIP has generated a 20:1 return in terms of sales values to grants, and an 8:1 return in sales versus program appropriations. It is estimated that 25% of all ERIP inventions had achieved sales by the end of 1990. While it is difficult to make exact comparisons between these percentages and other indicators of the success rates of technological innovations as a whole, the ERIP figures remain impressive. The commercial progress of spin-off technologies is also documented.

Macrophage origin limits functional plasticity in helminth-bacterial co-infection.

Directory of Open Access Journals (Sweden)

Dominik Rückerl

2017-03-01

Full Text Available Rapid reprogramming of the macrophage activation phenotype is considered important in the defense against consecutive infection with diverse infectious agents. However, in the setting of persistent, chronic infection the functional importance of macrophage-intrinsic adaptation to changing environments vs. recruitment of new macrophages remains unclear. Here we show that resident peritoneal macrophages expanded by infection with the nematode Heligmosomoides polygyrus bakeri altered their activation phenotype in response to infection with Salmonella enterica ser. Typhimurium in vitro and in vivo. The nematode-expanded resident F4/80high macrophages efficiently upregulated bacterial induced effector molecules (e.g. MHC-II, NOS2 similarly to newly recruited monocyte-derived macrophages. Nonetheless, recruitment of blood monocyte-derived macrophages to Salmonella infection occurred with equal magnitude in co-infected animals and caused displacement of the nematode-expanded, tissue resident-derived macrophages from the peritoneal cavity. Global gene expression analysis revealed that although nematode-expanded resident F4/80high macrophages made an anti-bacterial response, this was muted as compared to newly recruited F4/80low macrophages. However, the F4/80high macrophages adopted unique functional characteristics that included enhanced neutrophil-stimulating chemokine production. Thus, our data provide important evidence that plastic adaptation of MΦ activation does occur in vivo, but that cellular plasticity is outweighed by functional capabilities specific to the tissue origin of the cell.

Deep Brain Stimulation for Movement Disorders of Basal Ganglia Origin: Restoring Function or Functionality?

Science.gov (United States)

Wichmann, Thomas; DeLong, Mahlon R

2016-04-01

Deep brain stimulation (DBS) is highly effective for both hypo- and hyperkinetic movement disorders of basal ganglia origin. The clinical use of DBS is, in part, empiric, based on the experience with prior surgical ablative therapies for these disorders, and, in part, driven by scientific discoveries made decades ago. In this review, we consider anatomical and functional concepts of the basal ganglia relevant to our understanding of DBS mechanisms, as well as our current understanding of the pathophysiology of two of the most commonly DBS-treated conditions, Parkinson's disease and dystonia. Finally, we discuss the proposed mechanism(s) of action of DBS in restoring function in patients with movement disorders. The signs and symptoms of the various disorders appear to result from signature disordered activity in the basal ganglia output, which disrupts the activity in thalamocortical and brainstem networks. The available evidence suggests that the effects of DBS are strongly dependent on targeting sensorimotor portions of specific nodes of the basal ganglia-thalamocortical motor circuit, that is, the subthalamic nucleus and the internal segment of the globus pallidus. There is little evidence to suggest that DBS in patients with movement disorders restores normal basal ganglia functions (e.g., their role in movement or reinforcement learning). Instead, it appears that high-frequency DBS replaces the abnormal basal ganglia output with a more tolerable pattern, which helps to restore the functionality of downstream networks.

Social networks in the history of innovation and invention

CERN Document Server

Moon, Francis C

2014-01-01

This book integrates history of science and technology with modern social network theory. Using examples from the history of machines, as well as case studies from wireless, radio and chaos theory, the author challenges the genius model of invention. Network analysis concepts are presented to demonstrate the societal nature of invention in areas such as steam power, internal combustion engines, early aviation, air conditioning and more. Using modern measures of network theory, the author demonstrates that the social networks of invention from the 19th and early 20th centuries have similar characteristics to modern 21st C networks such as the World Wide Web. The book provides evidence that exponential growth in technical innovation is linked to the growth of historical innovation networks.

This article argues that mirror neurons originate in sensorimotor associative learning and therefore a new approach is needed to investigate their functions. Mirror neurons were discovered about 20 years ago in the monkey brain, and there is now evidence that they are also present in the human brain. The intriguing feature of many mirror neurons is that they fire not only when the animal is performing an action, such as grasping an object using a power grip, but also when the animal passively...

2013-12-01

Full Text Available Relation of Transparency and Economic growth is a long global debate in the society. Theoretically, policy makers, scholars and researchers argue that there is a close relation among these two variables. However, the quantitative relation and any global model is yet unrevealed. So, the main aim of this paper is to ascertain the nature, dimension and extent of the relationship between economy and Transparency as well as to invent a global model. This paper is useful for researchers, planners, policy makers and scholars who are directly or indirectly involved or willing to involve in the thrust for quantitative relation of these two variables. Literature review is the main source of information of this study. In introductory section, this paper briefly describes theoretical relationship of economy and Transparency as well as it also describes the proxy variables.GDP (2012 of different countries are used as proxy of Economy and Corruption Perception Index (CPI scores (2012 of different countries are used as proxy of level of Transparency. In methodology section this paper describes the detail methodology, sampling procedure and level of analysis. This study randomly selects 30 countries (10 from higher CPI scores+10 from moderate CPI scores+ 10 from lower CPI scores around the globe as sample. In the third section, this research presents the correlation value which divulge that there is a positive correlation (p=.047 with 95% confidence level. That reveals, if the level of transparency of any country increase, the GDP also increase accordingly. Then in this section two quantitative models are developed using linear regression analysis. First invented model is: Economy (GDP in billion US$ = [(8.983*Level of transparency -108.11]. This paper termed the first invented model as “Mahmud EcoT Model-1”. This model calibrates that one unit improvement of transparency leads 8.98 billion US$ improvement in the GDP of a country. Then taking this unit

Context-dependent memory traces in the crab’s mushroom bodies: Functional support for a common origin of high-order memory centers

Maza, Francisco Javier; Sztarker, Julieta; Shkedy, Avishag; Peszano, Valeria Natacha; Locatelli, Fernando Federico; Delorenzi, Alejandro

2016-01-01

The hypothesis of a common origin for the high-order memory centers in bilateral animals is based on the evidence that several key features, including gene expression and neuronal network patterns, are shared across several phyla. Central to this hypothesis is the assumption that the arthropods’ higher order neuropils of the forebrain [the mushroom bodies (MBs) of insects and the hemiellipsoid bodies (HBs) of crustaceans] are homologous structures. However, even though involvement in memory processes has been repeatedly demonstrated for the MBs, direct proof of such a role in HBs is lacking. Here, through neuroanatomical and immunohistochemical analysis, we identified, in the crab Neohelice granulata, HBs that resemble the calyxless MBs found in several insects. Using in vivo calcium imaging, we revealed training-dependent changes in neuronal responses of vertical and medial lobes of the HBs. These changes were stimulus-specific, and, like in the hippocampus and MBs, the changes reflected the context attribute of the memory trace, which has been envisioned as an essential feature for the HBs. The present study constitutes functional evidence in favor of a role for the HBs in memory processes, and provides key physiological evidence supporting a common origin of the arthropods’ high-order memory centers.

Musical emotions: Functions, origins, evolution

Science.gov (United States)

Perlovsky, Leonid

2010-03-01

Theories of music origins and the role of musical emotions in the mind are reviewed. Most existing theories contradict each other, and cannot explain mechanisms or roles of musical emotions in workings of the mind, nor evolutionary reasons for music origins. Music seems to be an enigma. Nevertheless, a synthesis of cognitive science and mathematical models of the mind has been proposed describing a fundamental role of music in the functioning and evolution of the mind, consciousness, and cultures. The review considers ancient theories of music as well as contemporary theories advanced by leading authors in this field. It addresses one hypothesis that promises to unify the field and proposes a theory of musical origin based on a fundamental role of music in cognition and evolution of consciousness and culture. We consider a split in the vocalizations of proto-humans into two types: one less emotional and more concretely-semantic, evolving into language, and the other preserving emotional connections along with semantic ambiguity, evolving into music. The proposed hypothesis departs from other theories in considering specific mechanisms of the mind-brain, which required the evolution of music parallel with the evolution of cultures and languages. Arguments are reviewed that the evolution of language toward becoming the semantically powerful tool of today required emancipation from emotional encumbrances. The opposite, no less powerful mechanisms required a compensatory evolution of music toward more differentiated and refined emotionality. The need for refined music in the process of cultural evolution is grounded in fundamental mechanisms of the mind. This is why today's human mind and cultures cannot exist without today's music. The reviewed hypothesis gives a basis for future analysis of why different evolutionary paths of languages were paralleled by different evolutionary paths of music. Approaches toward experimental verification of this hypothesis in

Functionalized Materials From Elastomers to High Performance Thermoplastics

Energy Technology Data Exchange (ETDEWEB)

Salazar, Laura Ann [Iowa State Univ., Ames, IA (United States)

2003-01-01

Synthesis and incorporation of functionalized materials continues to generate significant research interest in academia and in industry. If chosen correctly, a functional group when incorporated into a polymer can deliver enhanced properties, such as adhesion, water solubility, thermal stability, etc. The utility of these new materials has been demonstrated in drug-delivery systems, coatings, membranes and compatibilizers. Two approaches exist to functionalize a material. The desired moiety can be added to the monomer either before or after polymerization. The polymers used range from low glass transition temperature elastomers to high glass transition temperature, high performance materials. One industrial example of the first approach is the synthesis of Teflon(reg. sign). Poly(tetrafluoroethylene) (PTFE or Teflon(reg. sign)) is synthesized from tetrafluoroethylene, a functionalized monomer. The resulting material has significant property differences from the parent, poly(ethylene). Due to the fluorine in the polymer, PTFE has excellent solvent and heat resistance, a low surface energy and a low coefficient of friction. This allows the material to be used in high temperature applications where the surface needs to be nonabrasive and nonstick. This material has a wide spread use in the cooking industry because it allows for ease of cooking and cleaning as a nonstick coating on cookware. One of the best examples of the second approach, functionalization after polymerization, is the vulcanization process used to make tires. Natural rubber (from the Hevea brasiliensis) has a very low glass transition temperature, is very tacky and would not be useful to make tires without synthetic alteration. Goodyear's invention was the vulcanization of polyisoprene by crosslinking the material with sulfur to create a rubber that was tough enough to withstand the elements of weather and road conditions. Due to the development of polymerization techniques to make cis

Frederick Soddy's invention of isotopes in 1911

International Nuclear Information System (INIS)

Attas, M.

2011-01-01

This paper describes the history of the invention of isotopes by Frederick Soddy in 1911. The idea of the nucleus had been conceived by a physicist, Ernest Rutherford. But it took a chemist, Frederick Soddy, to make chemical sense of the zoo of recently discovered radioactive elements, by inventing the idea of isotopes. He showed how one radioactive substance transformed itself spontaneously into another, following mathematical laws of exponential growth and decay. In his book The Chemistry of the Radio-Elements, Soddy compiled complete descriptions of the physical and chemical properties of each of the radioactive substances. He organized their sequences of transmutations by the.similarities in their chemical properties, so that the emanations, for example, were all side-by-side in a chart.

DNA replication origin function is promoted by H3K4 di-methylation in Saccharomyces cerevisiae.

Science.gov (United States)

Rizzardi, Lindsay F; Dorn, Elizabeth S; Strahl, Brian D; Cook, Jeanette Gowen

2012-10-01

DNA replication is a highly regulated process that is initiated from replication origins, but the elements of chromatin structure that contribute to origin activity have not been fully elucidated. To identify histone post-translational modifications important for DNA replication, we initiated a genetic screen to identify interactions between genes encoding chromatin-modifying enzymes and those encoding proteins required for origin function in the budding yeast Saccharomyces cerevisiae. We found that enzymes required for histone H3K4 methylation, both the histone methyltransferase Set1 and the E3 ubiquitin ligase Bre1, are required for robust growth of several hypomorphic replication mutants, including cdc6-1. Consistent with a role for these enzymes in DNA replication, we found that both Set1 and Bre1 are required for efficient minichromosome maintenance. These phenotypes are recapitulated in yeast strains bearing mutations in the histone substrates (H3K4 and H2BK123). Set1 functions as part of the COMPASS complex to mono-, di-, and tri-methylate H3K4. By analyzing strains lacking specific COMPASS complex members or containing H2B mutations that differentially affect H3K4 methylation states, we determined that these replication defects were due to loss of H3K4 di-methylation. Furthermore, histone H3K4 di-methylation is enriched at chromosomal origins. These data suggest that H3K4 di-methylation is necessary and sufficient for normal origin function. We propose that histone H3K4 di-methylation functions in concert with other histone post-translational modifications to support robust genome duplication.

Cancer is the leading cause of death around the world. Anticancer activities from many functional food sources have been reported in years, but correlation between cancer prevalence and types of food with anticancer activities from crop origin center in the world as well as food source with human migration are unclear. Hunger from food shortage is the cause of early human evolution from Africa to Asia and later into Eurasia. The richest functional foods are found in crop origin centers, housing about 70% in the world populations. Crop origin centers have lower cancer incidence and mortality in the world, especially Central Asia, Middle East, Southwest China, India and Ethiopia. Asia and Africa with the richest anticancer crops is not only the most important evolution base of humans and origin center of anticancer functional crop, but also is the lowest mortality and incidence of cancers in the world. Cancer prevention of early human migrations was associated with functional foods from crop origin centers, especially Asia with four centers and one subcenter of crop origin, accounting for 58% of the world population. These results reveal that coevolution between human's anticancer activities associated with functional foods for crop origin centers, especially in Asia and Africa.

Invention profiles and uneven growth in the field of emerging nano-energy

International Nuclear Information System (INIS)

Guan, Jiancheng; Liu, Na

2015-01-01

This paper aims to synthetically investigate invention profiles and uneven growth of technological knowledge in the emerging nano-energy field, based on patents data extracted from the Derwent Innovation Index (DII) database during the time period 1991–2012. The trend analysis shows that invention in this field has experienced enormous growth and also diversification over the past 22 years. The co-occurrence network of burst technology domains reveals that technology domains constantly burst, and innovative progress in nanotechnology has tremendously contributed to energy production, storage, conversion and harvesting and so on. Nano-energy patented inventions mainly come from a combinatorial process with a very limited role of developing brand-new technological capabilities. Reusing existing technological capabilities including recombination reuse, recombination creation and single reuse is the primary source of inventions. For the impacts of technology networks' embeddedness, we find that network tie strength suppresses the growth of technological knowledge domains, and network status and convergence both facilitate the growth of technological knowledge domains. We expect that this study will provide some enlightenment for inventing or creating new knowledge in emerging fields in complex technological environment. - Highlights: • We define and utilize a unique dataset of nano-energy patents. • We identify and map the burst technological knowledge domains. • Quantitative argument is provided to prove the combinatorial invention. • Impacts of network embeddedness on growth of technology domain are examined. • Network characteristics affect the growth of technology domain

Inventing Freud.

Science.gov (United States)

Rudnytsky, Peter L

2008-06-01

Written to commemorate the 150th anniversary of Freud's birth, this paper construes Nina Coltart's statement that "if Freud did not exist it would be necessary to invent him," with its implicit comparison of Freud to God, to refer to (a) the things that Freud taught that are incontrovertibly true; (b) the unavoidable subjectivity in all judgments of Freud; and (c) the resemblances between psychoanalysis and religion. This last comparison is likewise seen to have both positive and negative aspects. Freud's ideas have inspired many people, yet he unscientifically arrogated sovereign authority over psychoanalysis. Freud's admirers are reminded of his extreme difficulty in admitting he was wrong and changing his mind when he should have known better, while his detractors are encouraged to consider the evidence supporting many of Freud's core tenets and to recognize that his discovery of psychoanalysis is indeed one of the supreme achievements in human history.

Full Text Available Inventários de fauna acessam diretamente a diversidade de uma localidade, em um determinado espaço e tempo. Os dados primários gerados pelos inventários compõem uma das ferramentas mais importantes na tomada de decisões a respeito do manejo de áreas naturais. Entretanto, vários problemas têm sido observados em diversos níveis relacionados aos inventários de fauna no Brasil e vão desde a formação de recursos humanos até a ausência de padronização, de desenho experimental e de seleção de métodos inadequados. São apresentados estudos de caso com mamíferos, répteis, anfíbios e peixes, nos quais são discutidos problemas como variabilidade temporal e métodos para detecção de fauna terrestre, sugerindo que tanto os inventários quanto os programas de monitoramento devam se estender por prazos maiores e que os inventários devem incluir diferentes metodologias para que os seus objetivos sejam plenamente alcançados.Inventories of fauna directly access the diversity of a locality in a certain period of time. The primary data generated by these inventories comprise one of the most important steps in decisions making regarding the management of natural areas. However, several problems have been observed at different levels related to inventories of fauna in Brazil, and range from the training of humans to the lack of standardization of experimental design and selection of inappropriate methods. We present case studies of mammals, reptiles, amphibians and fishes, where they discussed issues such temporal variability and methods for detection of terrestrial fauna, suggesting that both inventories and monitoring programs should be extended for longer terms and that inventories should include different methodologies to ensure that their goals are fully achieved.

The Microbiome of Seriola lalandi of Wild and Aquaculture Origin Reveals Differences in Composition and Potential Function

Carolina Ramírez

2017-09-01

Full Text Available Seriola lalandi is an economically important species that is globally distributed in temperate and subtropical marine waters. Aquaculture production of this species has had problems associated with intensive fish farming, such as disease outbreaks or nutritional deficiencies causing high mortalities. Intestinal microbiota has been involved in many processes that benefit the host, such as disease control, stimulation of the immune response, and the promotion of nutrient metabolism, among others. However, little is known about the potential functionality of the microbiota and the differences in the composition between wild and aquacultured fish. Here, we assayed the V4-region of the 16S rRNA gene using high-throughput sequencing. Our results showed that there are significant differences between S. lalandi of wild and aquaculture origin (ANOSIM and PERMANOVA, P < 0.05. At the genus level, a total of 13 genera were differentially represented between the two groups, all of which have been described as beneficial microorganisms that have an antagonistic effect against pathogenic bacteria, improve immunological parameters and growth performance, and contribute to nutrition. Additionally, the changes in the presumptive functions of the intestinal microbiota of yellowtail were examined by predicting the metagenomes using PICRUSt. The most abundant functional categories were those corresponding to the metabolism of cofactors and vitamins, amino acid metabolism and carbohydrate metabolism, revealing differences in the contribution of the microbiota depending on the origin of the animals. To our knowledge, this is the first study to characterize and compare the intestinal microbiota of S. lalandi of wild and aquaculture origin using high-throughput sequencing.

Mirror neurons: from origin to function.

Science.gov (United States)

Cook, Richard; Bird, Geoffrey; Catmur, Caroline; Press, Clare; Heyes, Cecilia

2014-04-01

This article argues that mirror neurons originate in sensorimotor associative learning and therefore a new approach is needed to investigate their functions. Mirror neurons were discovered about 20 years ago in the monkey brain, and there is now evidence that they are also present in the human brain. The intriguing feature of many mirror neurons is that they fire not only when the animal is performing an action, such as grasping an object using a power grip, but also when the animal passively observes a similar action performed by another agent. It is widely believed that mirror neurons are a genetic adaptation for action understanding; that they were designed by evolution to fulfill a specific socio-cognitive function. In contrast, we argue that mirror neurons are forged by domain-general processes of associative learning in the course of individual development, and, although they may have psychological functions, they do not necessarily have a specific evolutionary purpose or adaptive function. The evidence supporting this view shows that (1) mirror neurons do not consistently encode action "goals"; (2) the contingency- and context-sensitive nature of associative learning explains the full range of mirror neuron properties; (3) human infants receive enough sensorimotor experience to support associative learning of mirror neurons ("wealth of the stimulus"); and (4) mirror neurons can be changed in radical ways by sensorimotor training. The associative account implies that reliable information about the function of mirror neurons can be obtained only by research based on developmental history, system-level theory, and careful experimentation.

Guseinov, O.K.; Kasumov, F.K.; Yusifov, I.M.

1982-01-01

The star-formation function and the genetics of pulsar origin are discussed. It is shown that the progenitors of pulsars are main-sequence stars with masses of >5M/sub sun/ for almost all the kinds of initial mass functions discussed in the literature. Pulsars are genetically connected with supernova outbursts (mainly of type II). The probability of pulsar formation as a result of ''quiet collapse'' is extremely low. Thus, the hypothesis that pulsars are formed from objects of the extreme planar component of the Galaxy is confirmed on more complete and statistically uniform material

The Role of the Popes in the Invention of Complementarity and the Anathematization of Gender

Directory of Open Access Journals (Sweden)

Mary Anne Case

2016-03-01

Full Text Available This article examines the origins and uses by the Vatican of the theological anthropology of complementarity, arguing that the doctrine of complementarity, under which the sexes are essentially different though not unequal, is an invention of the twentieth century untraceable in earlier centuries, but developed by, among others, the Popes from Pius XII through Benedict XVI, in part as a response to feminist claims, including those recently anathematized by the Vatican under the term ‘gender.’ After exploring some difficulties with the application of the doctrine of complementarity as Catholic orthodoxy, the article concludes by compiling preliminary evidence as to the extent Pope Francis will continue his predecessors’ approach to complementarity.

HIGH ORIGIN OF SUPERFICIAL ULNAR ARTERY- A CASE REPORT

Directory of Open Access Journals (Sweden)

Anjana Jayakumaran Nair

2017-03-01

Full Text Available BACKGROUND High origin and superficially placed ulnar artery is a rare anatomical variant that usually arises either in the axilla or arm and runs a superficial course in the forearm, enters the hand and participates in the formation of superficial palmar arch. During routine dissection of cadavers in our department, we observed a unilateral case of high origin and superficial ulnar artery in a human male cadaver. It originated from the brachial artery in the lower third of arm 4 cm above its bifurcation. From its origin, it passed downwards along the medial aspect of forearm, superficial to the flexors, entered hand superficial to the flexor retinaculum and formed superficial palmar arch. The knowledge of existence of a superficial ulnar artery is important during vascular and reconstructive surgery and also in evaluation of angiographic images. Superficial position makes it more vulnerable to trauma and more accessible to cannulation.

From ecological records to big data: the invention of global biodiversity.

Science.gov (United States)

Devictor, Vincent; Bensaude-Vincent, Bernadette

2016-12-01

This paper is a critical assessment of the epistemological impact of the systematic quantification of nature with the accumulation of big datasets on the practice and orientation of ecological science. We examine the contents of big databases and argue that it is not just accumulated information; records are translated into digital data in a process that changes their meanings. In order to better understand what is at stake in the 'datafication' process, we explore the context for the emergence and quantification of biodiversity in the 1980s, along with the concept of the global environment. In tracing the origin and development of the global biodiversity information facility (GBIF) we describe big data biodiversity projects as a techno-political construction dedicated to monitoring a new object: the global diversity. We argue that, biodiversity big data became a powerful driver behind the invention of the concept of the global environment, and a way to embed ecological science in the political agenda.

Art, Science and the Invention of Things That Last

KAUST Repository

Edwards, David

2018-01-14

Aesthetic creation involves a close collaboration between discovery, invention and cultural exhibition, as well as between learning and producing value. It is typified by the patterns of creative behavior in highly innovative communities like Silicon Valley (for IT) or Boston (for biotech) where cultures of learning, experimentation, and production or commercialization coexist, and where a high degree of interdisciplinary collaboration occurs. In this lecture, David Edwards will highlight the growing movement of aesthetic creation in the arts, sciences and engineering as a path for sustaining and improving the human condition in the longest term. He will highlight aesthetic creation in the light of the culture lab model of Le Laboratoire (Paris, Cambridge) and the new World Frontiers Forum with examples of learning, pubic experimentation and value creation particularly related to the future of sensory experience.

The energy-related inventions program: Continuing benefits to the inventor community

Energy Technology Data Exchange (ETDEWEB)

Braid, R.B. Jr.; Brown, M.A.; Wilson, C.R.; Franchuk, C.A.; Rizy, C.G.

1996-10-01

This report provides information on the economic, energy, and environmental impacts of inventions supported by the Energy-Related Inventions Program (ERIP) - a technology commercialization program jointly operated by the U.S. Department of Energy (DOE) and the National Institute of Standards and Technology (NIST). It describes the results of the latest in a series of ERIP evaluation projects that have been completed since 1980. The period of interest is 1980 through 1994. The evaluation is based on data collected in 1995 through mail and telephone surveys of 211 program participants, and historical data collected during previous evaluations for an additional 253 participants. As of September 1993, a total of 609 inventions had been recommended to DOE by NIST, which screens all submitted inventions for technical merit, potential for commercial success, and potential energy impact. By the end of 1994, at least 144 (or 24%) of these inventions had entered the market, generating total cumulative sales of $961 million (in 19944). It is estimated that in 1994 ERIP inventors earned royalties of $2.3 million, and over the lifetime of the program, royalties total $28.2 million. With $47.5 million in grants awarded from 1975 through 1994 and $124 million in program appropriations over the same period, ERIP has generated a 20:1 return in terms of sales values to grants, and an 8:1 return in sales versus program appropriations. Further, it is estimated that at least 757 job-years of employment were supported by ERIP technologies in 1994, and that this resulted in a return of approximately $3.4 million in individual income taxes to the U.S. Treasury. Finally, approximately $334 million of energy expenditures were saved in 1994 as a result of the commercial success of five ERIP projects. These energy savings resulted in reduced emissions of 2.1 million metric tons of carbon in 1994 alone.

Invented spelling – a window on early literacy

Directory of Open Access Journals (Sweden)

Elżbieta Awramiuk

2014-01-01

Full Text Available A wide spectrum of research on preschool spelling development in different languages is presented. In Poland, children at kindergarten are usually at a stage of pre-literacy. Invented spelling means the writing produced by young children (aged 3–7 before they are formally taught reading and writing or are at the beginning of the learning process. Their writing is more spontaneous than learnt. The paper describes an investigation of the development of early literacy and factors influencing it, such as knowledge about orthography (spelling, early morphological awareness or teaching methods. Children’s early writing provides a window on their conceptualisation of the written language, illustrating the process of developing language awareness and spelling skills. Invented spelling, together with phonological abilities and letter knowledge is considered to be a strong predictor for later literacy skills.

Ding, Yi; Liu, Ru-De; McBride, Catherine A; Fan, Chung-Hau; Xu, Le; Wang, Jia

2018-05-07

This study examined pinyin (the official phonetic system that transcribes the lexical tones and pronunciation of Chinese characters) invented spelling and English invented spelling in 72 Mandarin-speaking 6th graders who learned English as their second language. The pinyin invented spelling task measured segmental-level awareness including syllable and phoneme awareness, and suprasegmental-level awareness including lexical tones and tone sandhi in Chinese Mandarin. The English invented spelling task manipulated segmental-level awareness including syllable awareness and phoneme awareness, and suprasegmental-level awareness including word stress. This pinyin task outperformed a traditional phonological awareness task that only measured segmental-level awareness and may have optimal utility to measure unique phonological and linguistic features in Chinese reading. The pinyin invented spelling uniquely explained variance in Chinese conventional spelling and word reading in both languages. The English invented spelling uniquely explained variance in conventional spelling and word reading in both languages. Our findings appear to support the role of phonological activation in Chinese reading. Our experimental linguistic manipulations altered the phonological awareness item difficulties.

Tree Ordination as Invented Tradition

Directory of Open Access Journals (Sweden)

Avery Morrow

2012-01-01

Full Text Available The symbolic ordination of trees as monks in Thailand is widely perceived in Western scholarship to be proof of the power of Buddhism to spur ecological thought. However, a closer analysis of tree ordination demonstrates that it is not primarily about Buddhist teaching, but rather is an invented tradition based on the sanctity of Thai Buddhist symbols as well as those of spirit worship and the monarchy. Tree ordinations performed by non-Buddhist minorities in Thailand do not demonstrate a religious commitment but rather a political one.

Using History to Teach Invention and Design: The Case of the Telephone

Science.gov (United States)

Gorman, Michael E.; Robinson, J. Kirby

This paper shows how a historical case, the invention of the telephone, can be used to teach invention and design in a way that combines engineering, social sciences, and humanities. The historical problem of transmitting speech was turned into an active learning module, in which students sought to improve patents obtained by early telephone inventors like Alexander Graham Bell and Elisha Gray, using equipment similar to what was available at the time. The result was a collaborative learning environment in which students from a wide range of majors worked in teams, eventually producing a patent application. As part of the project, they were allowed to search historical materials like the Bell notebooks, which were made available on line. This experience gave them a better understanding of the invention and design process.

We exploited the sequencing of the marmoset genome to identify 23,849 anthropoid-specific constrained (ASC) regions and confirmed their robust functional signatures. Of the ASC base pairs, 99.7% were noncoding, suggesting that novel anthropoid functional elements were overwhelmingly cis-regulatory. ASCs were highly enriched in loci associated with fetal brain development, motor coordination, neurotransmission, and vision, thus providing a large set of candidate elements for exploring the molecular basis of hallmark primate traits. We validated ASC192 as a primate-specific enhancer in proliferative zones of the developing brain. Unexpectedly, transposable elements (TEs) contributed to >56% of ASCs, and almost all TE families showed functional potential similar to that of nonrepetitive DNA. Three L1PA repeat-derived ASCs displayed coherent eye-enhancer function, thus demonstrating that the "gene-battery" model of TE functionalization applies to enhancers in vivo. Our study provides fundamental insights into genome evolution and the origins of anthropoid phenotypes and supports an elegantly simple new null model of TE exaptation. © 2014 del Rosario et al.; Published by Cold Spring Harbor Laboratory Press.

Comparative Study of the Role of Institutions in Shaping Inventive Activity in Mid-Range Emerging Economies

Directory of Open Access Journals (Sweden)

Ervits Irina

2016-12-01

Full Text Available The objective of this paper is to investigate the effects of institutions on national rates of inventive activity. Invention, part of the innovation process, is acknowledged as one of the driving forces behind economic growth, and patent statistics are frequently used as a measurable indicator of inventive output. Thus this paper explores the relationship between national patent statistics and measures of institutional quality. As a result of our research, the effect of the “threshold of inventive activity” was observed. This effect demonstrates that when countries reach a certain level of institutional development and attain a general institutional climate conducive to inventive activity, the number of patent applications begins to sharply increase. The paper contributes to the body of evidence that confirms that a combination of fundamental institutions like the rule of law or freedom of expression, which are not necessarily aimed at boosting innovation, create an overall environment conducive to patenting. We demonstrate that “mid-range emerging economies”,2 including those in Central and Eastern Europe3 (CEE, where the quality of institutions is lagging behind more developed counterparts and/or their influence is weak or sporadic, have not yet reached the threshold of inventive activity yet. However, those CEE countries that have acceded to the European Union first have made visible progress with respect to institutional quality and invention.

Japan has made 'innovation in science and technology' as one of its central pillars to ensure high growth in its next stage of economic development and its life sciences market which hosts regenerative medicine was proclaimed to be 'the best market in the world right now.' Although life science therapeutic inventions are patentable subject matter under Japanese patent law, there are nuanced obviousness and enablement challenges under Japanese patent law that can be surmounted in view of some encouraging Japanese court developments in fostering a pro-patent applicant environment in the life sciences therapeutic patent field. Nevertheless, great care must be taken when drafting and prosecuting such patent applications in the world's second most important life sciences therapeutic market.

Keys to Taking Your Nanotech Inventions to the Market

Science.gov (United States)

Rickert, Scott

Although many scientists and engineers may wish to be an owner of something they invented, and then take that something to the market, there are many obstacles to do so. Many of these roadblocks are self-imposed, and many more are there because most of us are not aware of the very strict rules that exist in the world of marketing, selling, and manufacturing in the United States. This lecture will identify a small subset of these obstacles and discuss some ways to overcome them. Belief in your goals is most important, and this belief must be shared by others, or you cannot succeed. Believe it or not, no one wants to steal your ideas or inventions. They would much rather have you take it to market yourself. This really is a lecture about winning.

The invention and early history of the CCD

International Nuclear Information System (INIS)

Smith, George E.

2009-01-01

As the first practical solid-state imaging device, the invention of the Charge Coupled Device has profoundly affected image sensing technology. They are used in a wide range of applications as both area and linear imaging devices starting with the replacement of imaging tubes used in commercial TV cameras and camcorders. The rapid increase of their use in digital cameras has initiated the demise of film photography and created vast new markets with great economic benefit for many. Other uses include a wide variety of scientific, surveillance and scanning applications. The inception of the device at Bell Labs by Willard S. Boyle and George E. Smith in 1969 was strongly influenced by several unique factors existing both within Bell Labs and the current world state of technology. These factors and their relevance will be discussed along with the train of thought leading to the invention. Early experimental devices and their initial applications were vigorously pursued and will be described. Current applications will be mentioned.

High Speed SPM of Functional Materials

Energy Technology Data Exchange (ETDEWEB)

Huey, Bryan D. [Univ. of Connecticut, Storrs, CT (United States)

2015-08-14

The development and optimization of applications comprising functional materials necessitates a thorough understanding of their static and dynamic properties and performance at the nanoscale. Leveraging High Speed SPM and concepts enabled by it, efficient measurements and maps with nanoscale and nanosecond temporal resolution are uniquely feasible. This includes recent enhancements for topographic, conductivity, ferroelectric, and piezoelectric properties as originally proposed, as well as newly developed methods or improvements to AFM-based mechanical, friction, thermal, and photoconductivity measurements. The results of this work reveal fundamental mechanisms of operation, and suggest new approaches for improving the ultimate speed and/or efficiency, of data storage systems, magnetic-electric sensors, and solar cells.

Collapse of the wave function models, ontology, origin, and implications

CERN Document Server

2018-01-01

This is the first single volume about the collapse theories of quantum mechanics, which is becoming a very active field of research in both physics and philosophy. In standard quantum mechanics, it is postulated that when the wave function of a quantum system is measured, it no longer follows the Schrödinger equation, but instantaneously and randomly collapses to one of the wave functions that correspond to definite measurement results. However, why and how a definite measurement result appears is unknown. A promising solution to this problem are collapse theories in which the collapse of the wave function is spontaneous and dynamical. Chapters written by distinguished physicists and philosophers of physics discuss the origin and implications of wave-function collapse, the controversies around collapse models and their ontologies, and new arguments for the reality of wave function collapse. This is an invaluable resource for students and researchers interested in the philosophy of physics and foundations of ...

Cognitive Function, Origin, and Evolution of Musical Emotions

Directory of Open Access Journals (Sweden)

Leonid Perlovsky

2013-12-01

Full Text Available Cognitive function of music, its origin, and evolution has been a mystery until recently. Here we discuss a theory of a fundamental function of music in cognition and culture. Music evolved in parallel with language. The evolution of language toward a semantically powerful tool required freeing from uncontrolled emotions. Knowledge evolved fast along with language. This created cognitive dissonances, contradictions among knowledge and instincts, which differentiated consciousness. To sustain evolution of language and culture, these contradictions had to be unified. Music was the mechanism of unification. Differentiated emotions are needed for resolving cognitive dissonances. As knowledge has been accumulated, contradictions multiplied and correspondingly more varied emotions had to evolve. While language differentiated psyche, music unified it. Thus the need for refined musical emotions in the process of cultural evolution is grounded in fundamental mechanisms of cognition. This is why today's human mind and cultures cannot exist without today's music.

Origin and function of myofibroblasts in kidney fibrosis.

LeBleu, Valerie S; Taduri, Gangadhar; O'Connell, Joyce; Teng, Yingqi; Cooke, Vesselina G; Woda, Craig; Sugimoto, Hikaru; Kalluri, Raghu

2013-08-01

Myofibroblasts are associated with organ fibrosis, but their precise origin and functional role remain unknown. We used multiple genetically engineered mice to track, fate map and ablate cells to determine the source and function of myofibroblasts in kidney fibrosis. Through this comprehensive analysis, we identified that the total pool of myofibroblasts is split, with 50% arising from local resident fibroblasts through proliferation. The nonproliferating myofibroblasts derive through differentiation from bone marrow (35%), the endothelial-to-mesenchymal transition program (10%) and the epithelial-to-mesenchymal transition program (5%). Specific deletion of Tgfbr2 in α-smooth muscle actin (αSMA)(+) cells revealed the importance of this pathway in the recruitment of myofibroblasts through differentiation. Using genetic mouse models and a fate-mapping strategy, we determined that vascular pericytes probably do not contribute to the emergence of myofibroblasts or fibrosis. Our data suggest that targeting diverse pathways is required to substantially inhibit the composite accumulation of myofibroblasts in kidney fibrosis.

Pinyin Invented Spelling in Mandarin Chinese-Speaking Children With and Without Reading Difficulties.

Science.gov (United States)

Ding, Yi; Liu, Ru-De; McBride, Catherine; Zhang, Dake

2015-01-01

This study examined analytical pinyin (a phonological coding system for teaching pronunciation and lexical tones of Chinese characters) skills in 54 Mandarin-speaking fourth graders by using an invented spelling instrument that tapped into syllable awareness, phoneme awareness, lexical tones, and tone sandhi in Chinese. Pinyin invented spelling was significantly correlated with Chinese character recognition and Chinese phonological awareness (i.e., syllable deletion and phoneme deletion). In comparison to good and average readers, poor readers performed significantly worse on the invented spelling task, and a difference was also found between average and good readers. To differentiate readers at different levels, the pinyin invented spelling task, which examined both segmental and suprasegmental elements, was superior to the typical phonological awareness task, which examined segments only. Within this new task, items involving tone sandhi (Chinese language changes in which the tones of words alter according to predetermined rules) were more difficult to manipulate than were those without tone sandhi. The findings suggest that this newly developed task may be optimal for tapping unique phonological and linguistic features in reading of Chinese and examining particular tonal difficulties in struggling Chinese readers. In addition, the results suggest that phonics manipulations within tasks of phonological and tonal awareness can alter their difficulty levels. © Hammill Institute on Disabilities 2014.

The nanotechnological inventions raise competitive ability of the products

Directory of Open Access Journals (Sweden)

2014-12-01

Full Text Available A brief description of the nanotechnological inventions is given. The inventions in the area of nanotechnologies and nanomaterials produce a profound effect in construction, housing and communal services and adjacent economic fields as they allow us: to obtain high strength and durability of surfaces of the details, to provide different materials with hydrophil properties, to increase efficiency of transformation of light energy into electrical one etc., and in general – to raise competitive ability of the products. For example, the method of production of solar element and a unit of solar elements (RU 2532137 comprises following stages: formation of pn-transfer in semiconductor base plate, formation of passivating layer on the light-receptive surface and/or non light-receptive surface of semiconductor base plate and formation of power robbing electrodes on the light-receptive surface and non light-receptive. A film of aluminium oxide is formed as passivating layer, its thickness is up to 40 nm, and lectrode is formed by baking conductive paste under the temperature 500–900ͦͦ°C for 1 second – 30 inutes with formation of sintered product. The sintered product penetrates through passivating layer setting electric contact between electrode and base plate. The formation of aluminium ide with specified thickness on the surface of base plate makes it possible to achieve good passivating characteristics and good electric contact between silica and electrode only by eans of baking conductive paste, that is standard technology. Moreover the baking stage which was necessary to get the effect of film passivation for aluminium oxide in the past now can be cancelled to decrease costs. The specialists may be also interested in the following nanotechnological inventions: reinforced flaked element made of natural or conglomerate stone and its multilayer protective coating (RU 2520193; fine organic suspension of carbon metal-containing nanostructures

The Invention of Tradition: Illyrian Heraldry

Directory of Open Access Journals (Sweden)

Aleksandar Palavestra

2016-02-01

Full Text Available The "Illyrian heraldry", as a phenomenon of the invented tradition, encompasses the rolls of arms - armorials, which appear in Dalmatia, Italy, Spain and Austria at the end of the XVI and beginning of the XVII century. These armorials contained Serbian and other southern Slav monarchic, territorial and family coats of arms. The authenticity, heraldic sources and origins of these armorials are extremely complex problems that can be traced back to the medieval heraldic heritage of the Serbs, on the one hand, and reveal the intricate web of political circumstances in the XVI and XVII centuries. Illyrian heraldry is also closely linked to the personal and political ambitions of the Spanish admiral, Don Pedro Ohmučević Grgurić, from Slano near Dubrovnik. One cannot, however, link the entire Illyrian heraldry movement only to the daring ambitions of Petar Ohmučević Grgurić In in the XVI and XVII centuries historical constructions, inspired for the most part by sincere Slav patriotism, emerged that proved the unity of the Illyrians and the Slavs, revealed the alleged Slav origins of famous figures (Alexander the Great, Justinian, or simply extolled the splendor and magnitude of a lost Slav kingdom, that could be restored again. Much as it was developing within the spiritual scope of the Catholic church, this "Slovine" movement found its historical basis in the medieval statehood of Serbia and Bosnia, particularly in the powerful empire of Stephan Dushan (1331-55, in the Serbian potentates, heroes, their glitter and opulence, which used to glorify the Slav world. Since the XVII century till today, despite their doubtful authenticity, the Illyrian armorials have been considered important genealogical and heraldic documents. Many families relied on the information in Illyrian heraldic collections when claiming their true, or, more often purported, ancient hereditary rights, titles and lands. The Illyrian armorials were transcribed and reprinted in

From the birth of the smokers’ clinic to the invention of Nicorette: Problematizing smoking as addiction in Sweden 1955–1971

Directory of Open Access Journals (Sweden)

Elam Mark

2014-12-01

Full Text Available AIM - To discuss how scientific confirmation of cigarette smoking as a major contemporary drug problem during the 1980s was preceded by a rising tide of clinical and pharmaceutical innovation dedicated to treating smoking as a problem of addiction. BACKGROUND - This current of innovation, commencing already in the 1950s, carried the smokers’ clinic and nicotine replacement therapies (NRTs into the world, both of which were originally invented and pioneered in Sweden. It is argued that both of these inventions were vital for advancing the problematization of smoking as a matter of nicotine addiction. While the British doctor Lennox Johnston is well-known for his early attempts to demonstrate the reality of smoking as nicotine addiction through auto-experimentation, the historical significance of Börje Ejrup’s founding of the first smokers’ clinics in Stockholm in the late 1950s has not been widely commented upon. Attempting to remedy this situation, the rise and fall of Ejrup’s clinics deploying lobeline substitution therapy as a cure for ‘nicotinism’ is outlined in the main body of the paper. FINDINGS - Although the clinical treatment of smoking as addiction lost momentum during the 1960s, the invention of Nicorette gum in southern Sweden at the end of the decade provided renewed impetus. Commencing in Helsingborg and Lund in 1970, the smokers’ clinic and NRTs entered into the long-term service of each other; a new combination that in just over a decade would succeed in propagating the reality of smoking as nicotine addiction on to a global stage.

Invention activities as preparation for learning laboratory data handling skills

Science.gov (United States)

Day, James

2012-10-01

Undergraduate physics laboratories are often driven by a mix of goals, and usually enough of them to cause cognitive overload for the student. Our recent findings align well with studies indicating that students often exit a physics lab without having properly learned how to handle real data. The value of having students explore the underlying structure of a problem before being able to solve it has been shown as an effective way to ready students for learning. Borrowing on findings from the fields of education and cognitive psychology, we use ``invention activities'' to precede direct instruction and bolster learning. In this talk I will show some of what we have learned about students' data handling skills, explain how an invention activity works, and share some observations of successful transfer.

Origin of the tail in Green's functions in odd-dimensional space-times

Science.gov (United States)

Dai, De-Chang; Stojkovic, Dejan

2013-10-01

It is well known that the scalar field Green's function in odd dimensions has a tail, i.e. a non-zero support inside the light cone, which in turn implies that the Huygens' principle is violated. However, the reason behind this behavior is still not quite clear. In this paper we shed more light on the physical origin of the tail by regularizing the term which is usually ignored in the literature since it vanishes due to the action of the delta function. With this extra term the Green's function does not satisfy the source-free wave equation (in the region outside of the source). We show that this term corresponds to a charge imprinted on the light-cone shell. Unlike the vector field charge, a moving scalar field charge is not Lorentz invariant and is contracted by a factor. If a scalar charge is moving at the speed of light, it appears to be zero in the static (with respect to the original physical charge) observer's frame. However, the field it sources is not entirely on the light cone. Thus, it is likely that this hidden charge sources the mysterious tail in odd dimensions.

Out of Africa: modern human origins special feature: human origins: out of Africa.

Science.gov (United States)

Tattersall, Ian

2009-09-22

Our species, Homo sapiens, is highly autapomorphic (uniquely derived) among hominids in the structure of its skull and postcranial skeleton. It is also sharply distinguished from other organisms by its unique symbolic mode of cognition. The fossil and archaeological records combine to show fairly clearly that our physical and cognitive attributes both first appeared in Africa, but at different times. Essentially modern bony conformation was established in that continent by the 200-150 Ka range (a dating in good agreement with dates for the origin of H. sapiens derived from modern molecular diversity). The event concerned was apparently short-term because it is essentially unanticipated in the fossil record. In contrast, the first convincing stirrings of symbolic behavior are not currently detectable until (possibly well) after 100 Ka. The radical reorganization of gene expression that underwrote the distinctive physical appearance of H. sapiens was probably also responsible for the neural substrate that permits symbolic cognition. This exaptively acquired potential lay unexploited until it was "discovered" via a cultural stimulus, plausibly the invention of language. Modern humans appear to have definitively exited Africa to populate the rest of the globe only after both their physical and cognitive peculiarities had been acquired within that continent.

Elements in the transcriptional regulatory region flanking herpes simplex virus type 1 oriS stimulate origin function.

Science.gov (United States)

Wong, S W; Schaffer, P A

1991-05-01

Like other DNA-containing viruses, the three origins of herpes simplex virus type 1 (HSV-1) DNA replication are flanked by sequences containing transcriptional regulatory elements. In a transient plasmid replication assay, deletion of sequences comprising the transcriptional regulatory elements of ICP4 and ICP22/47, which flank oriS, resulted in a greater than 80-fold decrease in origin function compared with a plasmid, pOS-822, which retains these sequences. In an effort to identify specific cis-acting elements responsible for this effect, we conducted systematic deletion analysis of the flanking region with plasmid pOS-822 and tested the resulting mutant plasmids for origin function. Stimulation by cis-acting elements was shown to be both distance and orientation dependent, as changes in either parameter resulted in a decrease in oriS function. Additional evidence for the stimulatory effect of flanking sequences on origin function was demonstrated by replacement of these sequences with the cytomegalovirus immediate-early promoter, resulting in nearly wild-type levels of oriS function. In competition experiments, cotransfection of cells with the test plasmid, pOS-822, and increasing molar concentrations of a competitor plasmid which contained the ICP4 and ICP22/47 transcriptional regulatory regions but lacked core origin sequences resulted in a significant reduction in the replication efficiency of pOS-822, demonstrating that factors which bind specifically to the oriS-flanking sequences are likely involved as auxiliary proteins in oriS function. Together, these studies demonstrate that trans-acting factors and the sites to which they bind play a critical role in the efficiency of HSV-1 DNA replication from oriS in transient-replication assays.

Function and Evolutionary Origin of Unicellular Camera-Type Eye Structure

KAUST Repository

Hayakawa, Shiho

2015-03-03

The ocelloid is an extraordinary eyespot organelle found only in the dinoflagellate family Warnowiaceae. It contains retina- and lens-like structures called the retinal body and the hyalosome. The ocelloid has been an evolutionary enigma because of its remarkable resemblance to the multicellular camera-type eye. To determine if the ocelloid is functionally photoreceptive, we investigated the warnowiid dinoflagellate Erythropsidinium. Here, we show that the morphology of the retinal body changed depending on different illumination conditions and the hyalosome manifests the refractile nature. Identifying a rhodopsin gene fragment in Erythropsidinium ESTs that is expressed in the retinal body by in situ hybridization, we also show that ocelloids are actually light sensitive photoreceptors. The rhodopsin gene identified is most closely related to bacterial rhodopsins. Taken together, we suggest that the ocelloid is an intracellular camera-type eye, which might be originated from endosymbiotic origin. © 2015 Hayakawa et al.

Neural origins of psychosocial functioning impairments in major depression.

Science.gov (United States)

Pulcu, Erdem; Elliott, Rebecca

2015-09-01

Major depressive disorder, a complex neuropsychiatric condition, is associated with psychosocial functioning impairments that could become chronic even after symptoms remit. Social functioning impairments in patients could also pose coping difficulties to individuals around them. In this Personal View, we trace the potential neurobiological origins of these impairments down to three candidate domains-namely, social perception and emotion processing, motivation and reward value processing, and social decision making. We argue that the neural basis of abnormalities in these domains could be detectable at different temporal stages during social interactions (eg, before and after decision stages), particularly within frontomesolimbic networks (ie, frontostriatal and amygdala-striatal circuitries). We review some of the experimental designs used to probe these circuits and suggest novel, integrative approaches. We propose that an understanding of the interactions between these domains could provide valuable insights for the clinical stratification of major depressive disorder subtypes and might inform future developments of novel treatment options in return.

The effects of a high-animal- and a high-vegetable-protein diet on mineral balance and bowel function of young men.

Science.gov (United States)

Van Dokkum, W; Wesstra, A; Luyken, R; Hermus, R J

1986-09-01

1. Twelve young men were given for periods of 20 d, each of three mixed diets, namely a low-protein (LP) diet (9% total energy as protein, 67% of animal origin), a high-animal-protein (HA) diet (16% total energy as protein, 67% of animal origin) and a high-vegetable-protein (HV) diet (16% total energy as protein, 67% of vegetable origin). Retention of calcium, magnesium, iron, zinc and copper as well as various bowel function indices were investigated during each dietary period. 2. Neither the HA diet nor the HV diet changed the retention of the minerals considerably. Only Fe balance decreased significantly on the HV diet. 3. Substituting the HV diet for the HA diet resulted in significant increases in faecal wet weight (17 g/d), defaecation frequency (0.12 stools/d), faecal volatile fatty acids (2.6 mmol/d) and a decrease in faecal bile acids (128 mumol/d). 4. It is concluded that a HV diet, rather than a HA diet is to be recommended with respect to bowel function, whereas the HV diet does not necessarily have a significant influence on mineral retention.

Full Text Available The young generation of today must be prepared with the knowledge and skills necessary to be able to compete globally thus boosting economic growth and prosperity. Therefore, students should not only be equipped with knowledge but they are in need of the “21st century skills”, which is the top priority and one of the main education agenda goals today. As one of the domains in the 21st century skills, inventive thinking includes elements of flexibility, self-regulation, curiosity, creativity, risk taking, higher order thinking and reasoning. In order to inculcate inventive thinking for students, the EkSTEMiT Learning Module was developed for the topic Electrochemistry; one of the most difficult topics to learn among students. EkSTEMiT Learning Module was developed based on the STEM (Science, Technology, Engineering and Mathematics integrated model. Thus, this paper will discuss the conceptual framework underlying the development of EkSTEMiT Learning Module with descriptions of learning activities designed for Electrochemistry.

2011-04-07

Fanconi anemia is characterized by congenital abnormalities, bone marrow failure, and cancer predisposition. To investigate the origin, functional role, and clinical impact of FANCA mutations, we determined a FANCA mutational spectrum with 130 pathogenic alleles. Some of these mutations were further characterized for their distribution in populations, mode of emergence, or functional consequences at cellular and clinical level. The world most frequent FANCA mutation is not the result of a mutational "hot-spot" but results from worldwide dissemination of an ancestral Indo-European mutation. We provide molecular evidence that total absence of FANCA in humans does not reduce embryonic viability, as the observed frequency of mutation carriers in the Gypsy population equals the expected by Hardy-Weinberg equilibrium. We also prove that long distance Alu-Alu recombination can cause Fanconi anemia by originating large interstitial deletions involving FANCA and 2 adjacent genes. Finally, we show that all missense mutations studied lead to an altered FANCA protein that is unable to relocate to the nucleus and activate the FA/BRCA pathway. This may explain the observed lack of correlation between type of FANCA mutation and cellular phenotype or clinical severity in terms of age of onset of hematologic disease or number of malformations.

Ethical limitations in patenting biotechnological inventions.

Science.gov (United States)

Lugagnani, V

1999-01-01

In order to connect ethical considerations with practical limits to patentability, the moral judgement should possibly move from the exploitation of the invention to the nature and/or objectives of Research and Development (R&D) projects which have produced it: in other words, it appears quite reasonable and logical that Society is not rewarding unethical R&D activities by granting intellectual property rights. As far as biotechnology R&D is concerned, ethical guidance can be derived from the 1996 Council of EuropeOs OConvention for the protection of human rights and dignity of the human being with regard to the application of biology and medicineO, whose Chapter V - Scientific research - provides guidelines on: i. protection of persons undergoing research (e.g. informed consent); ii. protection of persons not able to consent to research; iii. research on embryos in vitro. As far as the specific point of patenting biotechnology inventions is concerned, the four exclusions prescribed by Directive 98/44/EC (i.e. human cloning, human germ-line gene therapy, use of human embryos for commercial purposes, unjustified animal suffering for medical purposes) are all we have in Europe in terms of ethical guidance to patentability. In Italy, in particular, we certainly need far more comprehensive legislation, expressing SocietyOs demand to provide ethical control of modern biotechnology. However it is quite difficult to claim that ethical concerns are being raised by currently awarded biotechnology patents related to living organisms and material thereof; they largely deal with the results of genomic R&D, purposely and usefully oriented toward improving health-care and agri-food processes, products and services. ONo patents on lifeOO can be an appealing slogan of militants against modern biotechnology, but it is far too much of an over-simplified abstraction to become the Eleventh Commandment our Society.

Ancient Origin of the CARD–Coiled Coil/Bcl10/MALT1-Like Paracaspase Signaling Complex Indicates Unknown Critical Functions

Directory of Open Access Journals (Sweden)

Jens Staal

2018-05-01

Full Text Available The CARD–coiled coil (CC/Bcl10/MALT1-like paracaspase (CBM signaling complexes composed of a CARD–CC family member (CARD-9, -10, -11, or -14, Bcl10, and the type 1 paracaspase MALT1 (PCASP1 play a pivotal role in immunity, inflammation, and cancer. Targeting MALT1 proteolytic activity is of potential therapeutic interest. However, little is known about the evolutionary origin and the original functions of the CBM complex. Type 1 paracaspases originated before the last common ancestor of planulozoa (bilaterians and cnidarians. Notably in bilaterians, Ecdysozoa (e.g., nematodes and insects lacks Bcl10, whereas other lineages have a Bcl10 homolog. A survey of invertebrate CARD–CC homologs revealed such homologs only in species with Bcl10, indicating an ancient common origin of the entire CBM complex. Furthermore, vertebrate-like Syk/Zap70 tyrosine kinase homologs with the ITAM-binding SH2 domain were only found in invertebrate organisms with CARD–CC/Bcl10, indicating that this pathway might be related to the original function of the CBM complex. Moreover, the type 1 paracaspase sequences from invertebrate organisms that have CARD–CC/Bcl10 are more similar to vertebrate paracaspases. Functional analysis of protein–protein interactions, NF-κB signaling, and CYLD cleavage for selected invertebrate type 1 paracaspase and Bcl10 homologs supports this scenario and indicates an ancient origin of the CARD–CC/Bcl10/paracaspase signaling complex. By contrast, many of the known MALT1-associated activities evolved fairly recently, indicating that unknown functions are at the basis of the protein conservation. As a proof-of-concept, we provide initial evidence for a CBM- and NF-κB-independent neuronal function of the Caenorhabditis elegans type 1 paracaspase malt-1. In conclusion, this study shows how evolutionary insights may point at alternative functions of MALT1.

La voce senz’anima: origine e storia del Vocoder

Full Text Available A review of the cultural origins of the speaking machines is proposed. These origins are identified in the separation between soul and body, proposed by Descartes. The speaking machines, and then the vocoder, are substantially formed by a controlled part and an automatic part; in the voder, the synthetic speaker is directly controlled by a human being, conversely in the vocoder an authomatic process is implemented. Through historical examples such as the ‘automata’ by Mical, Kratzenstein, von Kempelen, Wheatstone, Helmoltz, until the invention of the Dudley’s vocoder, are described a growth and a stratification of devices and synthesizers applied to varied fields (signal representation, encrypted transmission, medical apparatus, cybernetic, music. The historical period treated ideally ends with Dolson’s article written in 1986, “The Phase Vocoder: A Tutorial”. Through musical examples is described the origin of control data handling in composition. The musical application of the phase vocoder describes the distinction between control and synthesis better than other technologies. Both control (parameter values and synthesis (instruments design are compositional problems that involve all the electroacoustic music composers.

Modelling Chemical Reasoning to Predict and Invent Reactions.

Science.gov (United States)

Segler, Marwin H S; Waller, Mark P

2017-05-02

The ability to reason beyond established knowledge allows organic chemists to solve synthetic problems and invent novel transformations. Herein, we propose a model that mimics chemical reasoning, and formalises reaction prediction as finding missing links in a knowledge graph. We have constructed a knowledge graph containing 14.4 million molecules and 8.2 million binary reactions, which represents the bulk of all chemical reactions ever published in the scientific literature. Our model outperforms a rule-based expert system in the reaction prediction task for 180 000 randomly selected binary reactions. The data-driven model generalises even beyond known reaction types, and is thus capable of effectively (re-)discovering novel transformations (even including transition metal-catalysed reactions). Our model enables computers to infer hypotheses about reactivity and reactions by only considering the intrinsic local structure of the graph and because each single reaction prediction is typically achieved in a sub-second time frame, the model can be used as a high-throughput generator of reaction hypotheses for reaction discovery. © 2017 Wiley-VCH Verlag GmbH & Co.

Highlights: • Our chemical analysis determines the important functional groups of cathode’s solid electrolyte interface originated from salt type additives. • Our quantum chemical calculation reveals the redox character of the additives and their candidate chemical components of the solid electrolyte interface. • Our molecular dynamics simulation reproduces the selective lithium ion translocation and protective layer formation as the solid electrolyte interface function. - Abstract: This is the study about the cathode’s solid electrolyte interface (SEI) formation mechanism of salt type additives (STAs) and its function. To address this issue, we performed several types of chemical analysis and computer simulation techniques. In order to reveal the redox nature and oxidative decomposition dynamics, the electrolyte (EL) solution dynamics by Quantum mechanics and Molecular mechanics (QM/MM) method was applied. The estimation of SEI chemical components agrees with our chemical analyses data and other group’s reports. The molecular dynamics simulation of sub micro second sampling indicates that the SEI phase induced from STAs functions as a lithium ion selective translocation media and protective coating layer against the degradation of the solvent molecules. The results give us an insight how to design additive’s chemical structure to improve longevity of the cell in the high voltage regime.

Invented Spelling, Word Stress, and Syllable Awareness in Relation to Reading Difficulties in Children.

Mehta, Sheena; Ding, Yi; Ness, Molly; Chen, Eric C

2018-06-01

The study assessed the clinical utility of an invented spelling tool and determined whether invented spelling with linguistic manipulation at segmental and supra-segmental levels can be used to better identify reading difficulties. We conducted linguistic manipulation by using real and nonreal words, incorporating word stress, alternating the order of consonants and vowels, and alternating the number of syllables. We recruited 60 third-grade students, of which half were typical readers and half were poor readers. The invented spelling task consistently differentiated those with reading difficulties from typical readers. It explained unique variance in conventional spelling, but not in word reading. Word stress explained unique variance in both word reading and conventional spelling, highlighting the importance of addressing phonological awareness at the supra-segmental level. Poor readers had poorer performance when spelling both real and nonreal words and demonstrated substantial difficulty in detecting word stress. Poor readers struggled with spelling words with double consonants at the beginning and ending of words, and performed worse on spelling two- and three-syllable words than typical readers. Practical implications for early identification and instruction are discussed.

Highly Stable Bimetallic AuIr/TiO₂ Catalyst: Physical Origins of the Intrinsic High Stability against Sintering.

It has been a long-lived research topic in the field of heterogeneous catalysts to find a way of stabilizing supported gold catalyst against sintering. Herein, we report highly stable AuIr bimetallic nanoparticles on TiO2 synthesized by sequential deposition-precipitation. To reveal the physical origin of the high stability of AuIr/TiO2, we used aberration-corrected scanning transmission electron microscopy (STEM), STEM-tomography, and density functional theory (DFT) calculations. Three-dimensional structures of AuIr/TiO2 obtained by STEM-tomography indicate that AuIr nanoparticles on TiO2 have intrinsically lower free energy and less driving force for sintering than Au nanoparticles. DFT calculations on segregation behavior of AuIr slabs on TiO2 showed that the presence of Ir near the TiO2 surface increases the adhesion energy of the bimetallic slabs to the TiO2 and the attractive interactions between Ir and TiO2 lead to higher stability of AuIr nanoparticles as compared to Au nanoparticles.

Inventing and naming America:  Place and Place Names in Vladimir Nabokov’s Lolita

Directory of Open Access Journals (Sweden)

Monica Manolescu-Oancea

2009-06-01

Full Text Available In the afterword to Lolita, Nabokov claimed that in this book he had to invent both Lolita and America after having invented Europe in his previous fiction. This paper focuses precisely on the various ways in which Nabokov “invented” America in his best-known novel. This invention is first of all the result of the author’s evolving stance on the complexity of what he called “average ‘reality’” in his works. Through a survey of Nabokov’s statements on the choice and role of place in the forewords to his Russian works and in his critical texts, I show that Lolita is indeed considered by Nabokov to be a “recreation” of American reality, to a much greater extent than his Russian works had been recreations of a given milieu. I take the metaphor of the “crazy quilt” mentioned in Lolita to suggest complexity, chromatic exuberance, hybridity. The invention of America is also the result of a process of naming. Place names will be examined, not only those which make up Quilty’s “cryptogrammic paperchase”, but also Humbert’s choice of place names. The problem of referentiality is discussed and the way recent criticism has dealt with it. Finally, the interplay between one and many is emphasized, the way in which the diversity of the “crazy quilt” is counterbalanced by the uniqueness of the mastermind having produced it. The American motto “From many make one” could be reinterpreted as “From one make many”.

Hydrotalcites: a highly efficient ecomaterial for effluent treatment originated from carbon nanotubes chemical processing

It has been reported that a mixture of carboxylated carbonaceous fragments (CCFs), so called oxidation debris, are generated during carbon nanotubes chemical processing using oxidant agents such as HNO{sub 3}. The elimination of these fragments from carbon nanotubes surface has been point out to be a crucial step for an effective functionalization of the nanotubes as well as for improving the material. However, this process can introduce a potential environmental problem related water contamination because these CCFs can be viewed as a mixture of carbonaceous polyaromatic systems similar to humic substances and dissolved organic matter (DOM). The negative aspects of humic substances and DOM to water quality and wastewater treatment are well known. Since carbon nanotubes industry expands at high rates it is expected that effluent containing oxidation debris will increase since HNO{sub 3} chemical processing is the most applied method for purification and functionalization of carbon nanotubes. In this work, we have demonstrated that Hydrotalcites (HT) are highly efficient to remove oxidation debris from effluent solution originated from HNO{sub 3}-treated multiwalled carbon nanotubes. The strategy presented here is a contribution towards green chemistry practices and life cycle studies in carbon nanotubes field.

We explore functional programming through a 16-week internship at Los Alamos National Laboratory. Functional programming is a branch of computer science that has exploded in popularity over the past decade due to its high-level syntax, ease of parallelization, and abundant applications. First, we summarize functional programming by listing the advantages of functional programming languages over the usual imperative languages, and we introduce the concept of parsing. Second, we discuss the importance of lambda calculus in the theory of functional programming. Lambda calculus was invented by Alonzo Church in the 1930s to formalize the concept of effective computability, and every functional language is essentially some implementation of lambda calculus. Finally, we display the lasting products of the internship: additions to a compiler and runtime system for the pure functional language STG, including both a set of tests that indicate the validity of updates to the compiler and a compiler pass that checks for illegal instances of duplicate names.

The current study examined how parental ethnic socialization informed adolescents’ ethnic identity development and, in turn, youths’ psychosocial functioning (i.e., mental health, social competence, academic efficacy, externalizing behaviors) among 749 Mexican-origin families. In addition, school ethnic composition was examined as a moderator of these associations. Findings indicated that mothers’ and fathers’ ethnic socialization were significant longitudinal predictors of adolescents’ ethnic identity, although fathers’ ethnic socialization interacted significantly with youths’ school ethnic composition in 5th grade to influence ethnic identity in 7th grade. Furthermore, adolescents’ ethnic identity was significantly associated with increased academic self-efficacy and social competence, and decreased depressive symptoms and externalizing behaviors. Findings support theoretical predictions regarding the central role parents play in Mexican-origin adolescents’ normative developmental processes and adjustment and, importantly, underscore the need to consider variability that is introduced into these processes by features of the social context such as school ethnic composition.

In 1967 a group of physicists from the University of Bologna, led by A Zichichi, published a proposal to search for a heavy lepton using the Frascati (e + e - ) collider. The proposal, whose key pages are reproduced in this book on the 30th anniversary of the publication, was the consequence of many years of work started at CERN, where, in addition to the original idea of searching for a heavy lepton carrying its own leptonic number, new technologies were invented to allow the detection of a signal whose identification against the high background of hadronic processes was extremely difficult.M

High-Dimensional Function Approximation With Neural Networks for Large Volumes of Data.

Science.gov (United States)

Andras, Peter

2018-02-01

Approximation of high-dimensional functions is a challenge for neural networks due to the curse of dimensionality. Often the data for which the approximated function is defined resides on a low-dimensional manifold and in principle the approximation of the function over this manifold should improve the approximation performance. It has been show that projecting the data manifold into a lower dimensional space, followed by the neural network approximation of the function over this space, provides a more precise approximation of the function than the approximation of the function with neural networks in the original data space. However, if the data volume is very large, the projection into the low-dimensional space has to be based on a limited sample of the data. Here, we investigate the nature of the approximation error of neural networks trained over the projection space. We show that such neural networks should have better approximation performance than neural networks trained on high-dimensional data even if the projection is based on a relatively sparse sample of the data manifold. We also find that it is preferable to use a uniformly distributed sparse sample of the data for the purpose of the generation of the low-dimensional projection. We illustrate these results considering the practical neural network approximation of a set of functions defined on high-dimensional data including real world data as well.

Methods and systems for performing arithmetic functions. In accordance with a first aspect of the invention, methods and apparatus are provided, working in conjunction of software algorithms and hardware implementation of class network routing, to achieve a very significant reduction in the time required for global arithmetic operation on the torus. Therefore, it leads to greater scalability of applications running on large parallel machines. The invention involves three steps in improving the efficiency and accuracy of global operations: (1) Ensuring, when necessary, that all the nodes do the global operation on the data in the same order and so obtain a unique answer, independent of roundoff error; (2) Using the topology of the torus to minimize the number of hops and the bidirectional capabilities of the network to reduce the number of time steps in the data transfer operation to an absolute minimum; and (3) Using class function routing to reduce latency in the data transfer. With the method of this invention, every single element is injected into the network only once and it will be stored and forwarded without any further software overhead. In accordance with a second aspect of the invention, methods and systems are provided to efficiently implement global arithmetic operations on a network that supports the global combining operations. The latency of doing such global operations are greatly reduced by using these methods.

Method of local pointed function reduction of original shape in Fourier transformation

International Nuclear Information System (INIS)

Dosch, H.; Slavyanov, S.Yu.

2002-01-01

The method for analytical reduction of the original shape in the one-dimensional Fourier transformation by the fourier image modulus is proposed. The basic concept of the method consists in the presentation of the model shape in the form of the local peak functions sum. The eigenfunctions, generated by the linear differential equations with the polynomial coefficients, are selected as the latter ones. This provides for the possibility of managing the Fourier transformation without numerical integration. This reduces the reverse task to the nonlinear regression with a small number of the evaluated parameters and to the numerical or asymptotic study on the model peak functions - the eigenfunctions of the differential tasks and their fourier images [ru

[Clinical Approach to Abdominal Pain as Functional Origin].

Science.gov (United States)

Ryu, Han Seung; Choi, Suck Chei

2018-02-25

Abdominal pain is a common symptom that patients refer to a hospital. Organic causes should be differentiated in patients with abdominal pain and treatment should be administered in accordance with the causes. A meticulous history taking and physical examination are highly useful in making a diagnosis, and blood tests, imaging modalities, and endoscopy are useful for confirming diagnosis. However, in many cases, patients have functional disorders with no obvious abnormal findings obtained even if many diagnostic tests are performed. Patients with functional disorders usually complain the vague abdominal pain located in the center and other portions of the abdominal area. Although the most representative disease is irritable bowel syndrome, functional abdominal pain syndrome is currently researched as a new disease entity of functional abdominal pain. As various receptors related to functional abdominal pain have been discovered, drugs associated with those receptors are used to treat the disorders, and additional new drugs are vigorously developed. In addition, medical therapy with pharmacological or non-pharmacological psychiatric treatment is effective for treating functional abdominal pain.

Origin of the p-type character of AuCl3 functionalized carbon nanotubes

KAUST Repository

Murat, Altynbek

2014-02-13

The microscopic origin of the p-type character of AuCl3 functionalized carbon nanotubes (CNTs) is investigated using first-principles self-interaction corrected density functional theory (DFT). Recent DFT calculations suggest that the p-type character of AuCl3 functionalized CNTs is due to the Cl atoms adsorbed on the CNTs. We test this hypothesis and show that adsorbed Cl atoms only lead to a p-type character for very specific concentrations and arrangements of the Cl atoms, which furthermore are not the lowest energy configurations. We therefore investigate alternative mechanisms and conclude that the p-type character is due to the adsorption of AuCl4 molecules. The unraveling of the exact nature of the p-doping adsorbates is a key step for further development of AuCl3 functionalized CNTs in water sensor applications. © 2014 American Chemical Society.

1993-01-01

The present invention concerns a high thermal load heat receiving plate such as a divertor plate of a thermonuclear device. The high thermal load heat receiving plate of the present invention has a cooling performance capable of suppressing the temperature of an armour tile to less than a threshold value of the material against high thermal loads applied from plasmas. Spiral polygonal pipes are inserted in cooling pipes at a portion receiving high thermal loads in the high temperature load heat receiving plate of the present invention. Both ends of the polygonal pipes are sealed by lids. An area of the flow channel in the cooling pipes is thus reduced. Heat conductivity on the cooling surface of the cooling pipes is increased in the high thermal load heat receiving plate having such a structure. Accordingly, temperature elevation of the armour tile can be suppressed. (I.S.)

Sur cette toile de fond, l’auteur propose une réinterprétation plus large de la notion de compétence.Social media practices encourage new approaches and visions of competence focusing on the construction of individual biography and the "invention of oneself". The new "artful skills" of "produsers" address the need to invent individual and collective responses to the sense of alienating emptiness pervading postindustrial and posttraditional societies. Combining and submission and opposition to both structuring and alienating aspects of late modernity, these produsagers actualize various tricks, tactics and immemorial schemes already mapped by various authors before the Internet. On this backdrop the author proposes a broader reinterpretation of the concept of competence.

Original high hydrocarbon groundwater represents a kind of groundwater in which hydrocarbon concentration exceeds 0.05 mg/L. The original high hydrocarbon will significantly reduce the environment capacity of hydrocarbon and lead environmental problems. For the past 5 years, we have carried out for a long-term monitoring of groundwater in shallow Triassic aquifer in Northwest Guizhou, China. We found the concentration of petroleum hydrocarbon was always above 0.05 mg/L. The low-level anthropogenic contamination cannot produce high hydrocarbon groundwater in the area. By using hydrocarbon potential, geochemistry and biomarker characteristic in rocks and shallow groundwater, we carried out a comprehensive study in Dalongjing (DLJ) groundwater system to determine the hydrocarbon source. We found a simplex hydrogeology setting, high-level water-rock-hydrocarbon interaction and obviously original hydrocarbon groundwater in DLJ system. The concentration of petroleum hydrocarbon in shallow aquifer was found to increase with the strong water-rock interaction. Higher hydrocarbon potential was found in the upper of Guanling formation (T 2 g 3 ) and upper of Yongningzhen formation (T 1 yn 4 ). Heavily saturated carbon was observed from shallow groundwater, which presented similar distribution to those from rocks, especially from the deeper groundwater. These results indicated that the high concentrations of original hydrocarbon in groundwater could be due to the hydrocarbon release from corrosion and extraction out of strata over time.

CERN Bulletin

2010-01-01

CERN has often been the incubator for the development of innovative technologies but very few people know about the capacitive touch screens invented for the consoles of the SPS Control Room in 1973. The Bulletin interviewed their inventor, Bent Stumpe, who also developed the CERN tracker ball and the computer-programmable knob.   Bent Stumpe, inventor of the CERN touch screens, tracker ball and programmable knob. Here we see him with one the first touch screens developed in 1973.   A specific goal, a lot of motivation and the technical skills to do it: that’s all you need to create something nobody else has ever done before. Back in the 1970s, the SPS was being built and its control room required the installation of thousands of buttons, knobs, switches and oscilloscopes to operate the machine. Frank Beck, newly recruited from the DD Division to be in charge of the central control hub in the SPS control room, asked Bent Stumpe for solutions to the following problem: how to bui...

2013-01-01

Full Text Available Based on two mythic figures − one belonging to classic Greece (the “Glowing Body”, and another to primitive Christianity (the “Heavenly Body” − I reflect on the symbolic logic of exclusion as enacted in four moments in the history of the Olympic Games. The first has to do with the invention of amateurism in the sporting philosophy of Coubertin, or the class exclusion. The second refers to the Anthropology Days held at the 1904 Olympic Games in Saint Louis (Missouri, or the ethnic/racial exclusion. The third is the Berlin Parade of Nations in 1936, or the national supremacy. The fourth explores the introduction of gender verification in Mexico City (1968, or the gender exclusion. In this fashion, we re-connect the imagined/imaginary configuration of the body with practices and politics which will result in an anthropological rationalization of discrimination.

Consciousness and the Invention of Morel

Directory of Open Access Journals (Sweden)

Lampros ePerogamvros

2013-03-01

Full Text Available A scientific study of consciousness should take into consideration both objective and subjective measures of conscious experiences. To this date, very few studies have tried to integrate third-person data, or data about the neurophysiological correlates of conscious states, with first-person data, or data about subjective experience. Inspired by Morel’s invention (Casares, 1940, a literary machine capable of reproducing sensory-dependent external reality, this article suggests that combination of virtual reality techniques and brain reading technologies, that is, decoding of conscious states by brain activity alone, can offer this integration. It is also proposed that the multimodal, simulating and integrative capacities of the dreaming brain render it an 'endogenous' Morel's machine, which can potentially be used in studying consciousness, but not always in a reliable way. Both the literary machine and dreaming could contribute to a better understanding of conscious states.

Bio-functions and molecular carbohydrate structure association study in forage with different source origins revealed using non-destructive vibrational molecular spectroscopy techniques.

Science.gov (United States)

Ji, Cuiying; Zhang, Xuewei; Yan, Xiaogang; Mostafizar Rahman, M; Prates, Luciana L; Yu, Peiqiang

2017-08-05

The objectives of this study were to: 1) investigate forage carbohydrate molecular structure profiles; 2) bio-functions in terms of CHO rumen degradation characteristics and hourly effective degradation ratio of N to OM (HED N/OM ), and 3) quantify interactive association between molecular structures, bio-functions and nutrient availability. The vibrational molecular spectroscopy was applied to investigate the structure feature on a molecular basis. Two sourced-origin alfalfa forages were used as modeled forages. The results showed that the carbohydrate molecular structure profiles were highly linked to the bio-functions in terms of rumen degradation characteristics and hourly effective degradation ratio. The molecular spectroscopic technique can be used to detect forage carbohydrate structure features on a molecular basis and can be used to study interactive association between forage molecular structure and bio-functions.

The Las Vegas Strip as a Genuinely Invented Global Landscape

Directory of Open Access Journals (Sweden)

Daniel Ortega

2004-12-01

Full Text Available Las Vegas, Nevada, is typically recognised as a place via a single urban gesture, that gesture being Las Vegas Boulevard, which is more commonly referred to as "The Strip". In constructing a thesis around the theme, "Here or There? Interconnections between the Global and the Local", one cannot ignore the invitation to discuss globalisation and its effects on a particular local fabric. For the purpose of this text, globalisation can be thought of as what Carmona et al describe as an intricate series of events leading to the world "becoming increasingly interconnected, with centralised decision making exploiting economies of scale and standardisation" (2003: 101. The centralised decision-making process for The Strip is evident in the strategy to develop individually themed casino resorts along Las Vegas Boulevard that respond to a competitive economy, thus creating a newly standardised landscape. If we also understand that globalisation can be thought of as the development of an interconnected world where economic, political and cultural boundaries can be easily crossed, this work can begin to define how the Las Vegas Strip is a genuinely invented global landscape. This paper addresses the "here-ness" as well as the "there-ness" of The Strip, while offering a dialectical framework for establishing a meaning of place by having 'there' placed 'here'. By employing semiological interpretations of real landscapes from around the globe (for example, Venturi et al, 1972, The Strip becomes a newly invented landscape of "simulations" (Baudrillard, 1988. As such, The Strip acts as a narrative that forms a unique place, opening the door to questions of authenticity and identity. This paper concludes by focusing on the question of "Here or There?" as an appropriate deviation from the assumed role that the post-modern landscape of the Las Vegas Strip plays. This work is intended to be a point of departure from the frequent criticism of the Las Vegas Strip as

A study of inventiveness among Society of Interventional Radiology members and the impact of their social networks.

Murphy, Kieran J; Elias, Gavin; Jaffer, Hussein; Mandani, Rashesh

2013-07-01

To investigate the nature of inventiveness among members of the Society of Interventional Radiology (SIR) and learn what influenced the inventors and assisted their creativity. The membership directory of the SIR was cross-referenced with filings at the United States Patent and Trademark Organization (USPTO) and the Patent Cooperation Treaty (PCT). The inventors were queried with an online survey to illuminate their institutions of training and practice as well as enabling or inhibiting factors to their inventiveness. Responses were analyzed through the construction of social network maps and thematic and graphical analysis. It was found that 457 members of the SIR held 2,492 patents or patent filings. After 1986, there was a marked and sustained increase in patent filings. The online survey was completed by 73 inventors holding 470 patents and patent filings. The social network maps show the key role of large academic interventional radiology departments and individual inventors in the formation of interconnectivity among inventors and the creation of the intellectual property (IP). Key inhibitors of the inventive process include lack of mentorship, of industry contacts, and of legal advice. Key enablers include mentorship, motivation, and industry contacts. Creativity and inventiveness in SIR members stem from institutions that are hubs of innovation and networks of key innovators; inventors are facilitated by personal motivation, mentorship, and strong industry contacts.

Proteome-level assessment of origin, prevalence and function of Leucine-Aspartic Acid (LD) motifs

KAUST Repository

Alam, Tanvir

2018-03-11

Short Linear Motifs (SLiMs) contribute to almost every cellular function by connecting appropriate protein partners. Accurate prediction of SLiMs is difficult due to their shortness and sequence degeneracy. Leucine-aspartic acid (LD) motifs are SLiMs that link paxillin family proteins to factors controlling (cancer) cell adhesion, motility and survival. The existence and importance of LD motifs beyond the paxillin family is poorly understood. To enable a proteome-wide assessment of these motifs, we developed an active-learning based framework that iteratively integrates computational predictions with experimental validation. Our analysis of the human proteome identified a dozen proteins that contain LD motifs, all being involved in cell adhesion and migration, and revealed a new type of inverse LD motif consensus. Our evolutionary analysis suggested that LD motif signalling originated in the common unicellular ancestor of opisthokonts and amoebozoa by co-opting nuclear export sequences. Inter-species comparison revealed a conserved LD signalling core, and reveals the emergence of species-specific adaptive connections, while maintaining a strong functional focus of the LD motif interactome. Collectively, our data elucidate the mechanisms underlying the origin and adaptation of an ancestral SLiM.

Origin of radium in high-mineralised waters

International Nuclear Information System (INIS)

Wiegand, J.W.; Sebastian, F.

2002-01-01

High-mineralised waters are showing frequently high concentrations of 226 Ra and 228 Ra, which are positively correlated with salinity. The investigated pit water is a high mineralised, reducing NaCl-brine (up to 230 g/l), which contains in coexcidence with Ba (up to 2500 ppm) and Sr, high 226 Ra concentrations (up to 63 Bq/l) and 228 Ra concentrations (up to 28 Bq/l). Feeding river systems with this water, the contact of the pit water with sulphate bearing surface water results in a precipitation of Ba and Ra as radiobaryte, with 226 Ra concentrations up to several tens of kBq/kg. The pit waters originate from a mixture of formation and meteoric waters, older than 20 Ma. High concentrations of mainly Na + and C1 - , but K + , Ca 2+ and HCO 3 - as well, are explained by dissolution of Permian salt deposits. Ba 2+ is enriched by sulphate-reducing bacteria, which destroy detrital baryte. Radium enters the water by leaching and alpha-recoil effect, but a large fraction of it is adsorbed at the surfaces of mineral grains. Mainly Ba 2+ and Sr 2+ , but univalent ions like Na + and K + as well, are desorbing Ra 2+ from the surface of minerals and take their place. Elution experiments show that beside the ion exchange of the cations, the type and amount of anions control the radium mobilisation. It seems that large anions like NO 3 - are disturbing the hydrate coat around minerals and therefore, enhance the ion exchange process. (author)

The practical Einstein experiments, patents, inventions

CERN Document Server

Illy, József

2012-01-01

Albert Einstein may be best known as the wire-haired whacky physicist who gave us the theory of relativity, but that's just one facet of this genius' contribution to human knowledge and modern science. As Jozsef Illy expertly shows in this book, Einstein had an eminently practical side as well. As a youth, Einstein was an inveterate tinkerer in the electrical supply factory his father and uncle owned and operated. His first paid job was as a patent examiner. Later in life, Einstein contributed to many inventions, including refrigerators, microphones, and instruments for aviation. In published papers, Einstein often provided ways to test his theories and fundamental problems of the scientific community of his times. He delved deeply into a variety of technological innovations, most notably the gyrocompass, and consulted for industry in patent cases and on other legal matters. Einstein also provided explanations for common and mundane phenomena, such as the meandering of rivers. In these and other hands-on exam...

Unveiling the high-activity origin of single-atom iron catalysts for oxygen reduction reaction.

2018-06-26

It is still a grand challenge to develop a highly efficient nonprecious-metal electrocatalyst to replace the Pt-based catalysts for oxygen reduction reaction (ORR). Here, we propose a surfactant-assisted method to synthesize single-atom iron catalysts (SA-Fe/NG). The half-wave potential of SA-Fe/NG is only 30 mV less than 20% Pt/C in acidic medium, while it is 30 mV superior to 20% Pt/C in alkaline medium. Moreover, SA-Fe/NG shows extremely high stability with only 12 mV and 15 mV negative shifts after 5,000 cycles in acidic and alkaline media, respectively. Impressively, the SA-Fe/NG-based acidic proton exchange membrane fuel cell (PEMFC) exhibits a high power density of 823 mW cm -2 Combining experimental results and density-functional theory (DFT) calculations, we further reveal that the origin of high-ORR activity of SA-Fe/NG is from the Fe-pyrrolic-N species, because such molecular incorporation is the key, leading to the active site increase in an order of magnitude which successfully clarifies the bottleneck puzzle of why a small amount of iron in the SA-Fe catalysts can exhibit extremely superior ORR activity.

The Democratic Invention. A Reading of Lefort.

Directory of Open Access Journals (Sweden)

Matías Sirczuk

2014-12-01

Full Text Available In this paper I will present the way in which Lefort interprets modern democracy as a new form of society in regard to the sources of law and legitimacy. Lefort is a thinker who is difficult to place within the context of contemporary political theory: he not only defends democracy against Marxism but also thinks that this form of society cannot be circumscribed within the limits of the modern state, nor be understood through the categories that the tradition of political philosophy has developed to distinguish between political regimes. Lefort combines the defense of democracy with a radical critique of the established order. He identifies the democratic invention with the institution of a dynamic that makes, by right, the radical questioning of law the source of political legitimacy.

Molecular Docking Explains Atomic Interaction between Plant-originated Ligands and Oncogenic E7 Protein of High Risk Human Papillomavirus Type 16

Directory of Open Access Journals (Sweden)

Satish Kumar

2014-12-01

Full Text Available Cervical cancer caused by Human papillomavirus (HPV is one of the leading causes of cancer mortality in women worldwide, particularly in the developing countries. In the last few decades, various compounds from plant origin such as Curcumin, Epigallocatechin gallate (EGCG, Jaceosidin, Resveratrol etc. have been used as anti cancer therapeutic agents. Different studies have shown these plant-originated compounds are able to suppress HPV infection. The E6 and E7 oncoproteins of high-risk HPV play a key role in HPV related cancers. In this study, we explored these ligands from plants origin against E7 oncoprotein of high risk HPV 16, which is known to inactivate tumor suppressor pRb protein. A robust homology model of HPV 16 E7 was built to foresee the interaction mechanism of E7 oncoprotein with these ligands using structure-based drug designing approach. Docking studies demonstrate the interaction of these ligands with pRb binding site of E7 protein by residues Tyr52, Asn53, Val55, Phe57, Cys59, Ser63, Thr64, Thr72, Arg77, Glu80 and Asp81 and help restoration of pRb functioning. This in silico based atomic interaction between these ligands and E7 protein may assist in validating the plant-originated ligands as effective drugs against HPV.

A supernova origin for dust in a high-redshift quasar.

Maiolino, R; Schneider, R; Oliva, E; Bianchi, S; Ferrara, A; Mannucci, F; Pedani, M; Sogorb, M Roca

2004-09-30

Interstellar dust plays a crucial role in the evolution of the Universe by assisting the formation of molecules, by triggering the formation of the first low-mass stars, and by absorbing stellar ultraviolet-optical light and subsequently re-emitting it at infrared/millimetre wavelengths. Dust is thought to be produced predominantly in the envelopes of evolved (age >1 Gyr), low-mass stars. This picture has, however, recently been brought into question by the discovery of large masses of dust in the host galaxies of quasars at redshift z > 6, when the age of the Universe was less than 1 Gyr. Theoretical studies, corroborated by observations of nearby supernova remnants, have suggested that supernovae provide a fast and efficient dust formation environment in the early Universe. Here we report infrared observations of a quasar at redshift 6.2, which are used to obtain directly its dust extinction curve. We then show that such a curve is in excellent agreement with supernova dust models. This result demonstrates a supernova origin for dust in this high-redshift quasar, from which we infer that most of the dust at high redshifts probably has the same origin.

High Rate of Chimeric Gene Origination by Retroposition in Plant Genomes

DEFF Research Database (Denmark)

Wang, Wen; Zheng, Hongkung; Fan, Chuanzhu

2006-01-01

Retroposition is widely found to play essential roles in origination of new mammalian and other animal genes. However, the scarcity of retrogenes in plants has led to the assumption that plant genomes rarely evolve new gene duplicates by retroposition, despite abundant retrotransposons in plants......, confirming a previously observed role of retroelements in generating plant retrogenes. Substitution analyses revealed that the vast majority are subject to negative selection, suggesting, along with expression data and evidence of age, that they are likely functional retrogenes. In addition, 42...

Emergence, Retention and Selection: A Trilogy of Origination for Functional De Novo Proteins from Ancestral LncRNAs in Primates.

Directory of Open Access Journals (Sweden)

Jia-Yu Chen

2015-07-01

Full Text Available While some human-specific protein-coding genes have been proposed to originate from ancestral lncRNAs, the transition process remains poorly understood. Here we identified 64 hominoid-specific de novo genes and report a mechanism for the origination of functional de novo proteins from ancestral lncRNAs with precise splicing structures and specific tissue expression profiles. Whole-genome sequencing of dozens of rhesus macaque animals revealed that these lncRNAs are generally not more selectively constrained than other lncRNA loci. The existence of these newly-originated de novo proteins is also not beyond anticipation under neutral expectation, as they generally have longer theoretical lifespan than their current age, due to their GC-rich sequence property enabling stable ORFs with lower chance of non-sense mutations. Interestingly, although the emergence and retention of these de novo genes are likely driven by neutral forces, population genetics study in 67 human individuals and 82 macaque animals revealed signatures of purifying selection on these genes specifically in human population, indicating a proportion of these newly-originated proteins are already functional in human. We thus propose a mechanism for creation of functional de novo proteins from ancestral lncRNAs during the primate evolution, which may contribute to human-specific genetic novelties by taking advantage of existed genomic contexts.

PHB genes are ubiquitously present in divergent species from prokaryotes to eukaryotes. Human PHB genes have been found to be associated with various diseases. Recent studies by our group and others have shown diverse function of PHB genes in plants for development, senescence, defence, and others. Despite the importance of the PHB gene family, no comprehensive gene family analysis has been carried to evaluate the relatedness of PHB genes across different species. In order to better guide the gene function analysis and understand the evolution of the PHB gene family, we therefore carried out the comparative genome analysis of the PHB genes across different kingdoms. The relatedness, motif distribution, and intron/exon distribution all indicated that PHB genes is a relatively conserved gene family. The PHB genes can be classified into 5 classes and each class have a very deep evolutionary origin. The PHB genes within the class maintained the same motif patterns during the evolution. With Arabidopsis as the model species, we found that PHB gene intron/exon structure and domains are also conserved during the evolution. Despite being a conserved gene family, various gene duplication events led to the expansion of the PHB genes. Both segmental and tandem gene duplication were involved in Arabidopsis PHB gene family expansion. However, segmental duplication is predominant in Arabidopsis. Moreover, most of the duplicated genes experienced neofunctionalization. The results highlighted that PHB genes might be involved in important functions so that the duplicated genes are under the evolutionary pressure to derive new function. PHB gene family is a conserved gene family and accounts for diverse but important biological functions based on the similar molecular mechanisms. The highly diverse biological function indicated that more research needs to be carried out

Generalizing, optimizing, and inventing numerical algorithms for the fractional Fourier, Fresnel, and linear canonical transforms

Science.gov (United States)

Hennelly, Bryan M.; Sheridan, John T.

2005-05-01

By use of matrix-based techniques it is shown how the space-bandwidth product (SBP) of a signal, as indicated by the location of the signal energy in the Wigner distribution function, can be tracked through any quadratic-phase optical system whose operation is described by the linear canonical transform. Then, applying the regular uniform sampling criteria imposed by the SBP and linking the criteria explicitly to a decomposition of the optical matrix of the system, it is shown how numerical algorithms (employing interpolation and decimation), which exhibit both invertibility and additivity, can be implemented. Algorithms appearing in the literature for a variety of transforms (Fresnel, fractional Fourier) are shown to be special cases of our general approach. The method is shown to allow the existing algorithms to be optimized and is also shown to permit the invention of many new algorithms.

Background NADPH oxidases (NOX) are ROS producing enzymes that perform essential roles in cell physiology, including cell signaling and antimicrobial defense. This gene family is present in most eukaryotes, suggesting a common ancestor. To date, only a limited number of phylogenetic studies of metazoan NOXes have been performed, with few arthropod genes. In arthropods, only NOX5 and DUOX genes have been found and a gene called NOXm was found in mosquitoes but its origin and function has not b...

Density functional theory: Its origins, rise to prominence, and future

Science.gov (United States)

Jones, R. O.

2015-07-01

In little more than 20 years, the number of applications of the density functional (DF) formalism in chemistry and materials science has grown in an astonishing fashion. The number of publications alone shows that DF calculations make up a huge success story, and many younger colleagues are surprised to learn that the widespread application of density functional methods, particularly in chemistry, began only after 1990. This is indeed unexpected, because the origins are usually traced to the papers of Hohenberg, Kohn, and Sham more than a quarter of a century earlier. The DF formalism, its applications, and prospects were reviewed for this journal in 1989. About the same time, the combination of DF calculations with molecular dynamics promised to provide an efficient way to study structures and reactions in molecules and extended systems. This paper reviews the development of density-related methods back to the early years of quantum mechanics and follows the breakthrough in their application after 1990. The two examples from biochemistry and materials science are among the many current applications that were simply far beyond expectations in 1990. The reasons why—50 years after its modern formulation and after two decades of rapid expansion—some of the most cited practitioners in the field are concerned about its future are discussed.

2017-01-01

The present invention is an improved fiber optic sensing system (FOSS) having the ability to provide both high spatial resolution and high frequency strain measurements. The inventive hybrid FOSS fiber combines sensors from high acquisition speed and low spatial resolution Wavelength-Division Multiplexing (WDM) systems and from low acquisition speed and high spatial resolution Optical Frequency Domain Reflection (OFDR) systems. Two unique light sources utilizing different wavelengths are coupled with the hybrid FOSS fiber to generate reflected data from both the WDM sensors and OFDR sensors operating on a single fiber optic cable without incurring interference from one another. The two data sets are then de-multiplexed for analysis, optionally with conventionally-available WDM and OFDR system analyzers.

Eastern Finns have higher risk of coronary heart disease (CHD) and carotid intima-media thickness than western Finns although current differences in CHD risk factors are minimal. Left ventricular (LV) mass and diastolic function predict future cardiovascular events but their east-west differences are unknown. We examined the association of eastern/western baseline origin with LV mass and diastolic function. The study population included 2045 subjects of the Cardiovascular Risk in Young Finns Study with data from the baseline survey (1980) and the latest follow-up (2011) when echocardiography was performed at the age of 34-49 years. Subjects with eastern baseline origin had in 2011 higher LV mass (139±1.0 vs. 135±1.0 g, p=0.006) and E/e'-ratio indicating weaker LV diastolic function (4.86±0.03 vs. 4.74±0.03, p=0.02) than western subjects. Results were independent of age, sex, area of examination and CHD risk factors such as blood pressure and BMI (LV mass indexed with height: porigin (135±0.9 vs. 131±0.9 ml, p=0.0011) but left atrial end-systolic volume, also indicating LV diastolic function, was not different between eastern and western subjects (43.4±0.5 vs. 44.0±0.5 ml, p=0.45). Most of the subjects were well within the normal limits of these echocardiographic measurements. In our healthy middle-aged population, geographic origin in eastern Finland associated with higher LV mass compared to western Finland. Higher E/e'-ratio suggests that subjects with eastern baseline origin might have higher prevalence of diastolic dysfunction in the future than western subjects.

The fossil record, function, and possible origins of shell color patterns in Paleozoic marine invertebrates

Energy Technology Data Exchange (ETDEWEB)

Kobluk, D.R. (Univ. of Toronto, Ontario (Canada)); Mapes, R.H. (Ohio Univ., Athens (USA))

1989-02-01

Fossil invertebrate shells and carapaces displaying preserved original color patterns are among the rarest fossils. The fossil record of color patterns extends into the Middle Cambrian where the trilobite Anomocare displays a fan-like array of stripes on the pygidium. About 180 Paleozic genera are known with patterns, including trilobites, cephalopods, gastropods, brachiopods, bivalves, crinoids, and crustaceans. Based upon an analysis of these taxa, it appears that patterns and pigments in middle and late Paleozoic invertebrates may have served several functions such as warning displays, light screening, camouflage, or waste disposal. However, the presence of color patterns in fossil invertebrates in the early Paleozoic may have developed prior to the evolution of vision sufficiently sophisticated to see them. This suggests that camouflage and warning displays were not the original functions of color patterns, and that in the earliest Paleozoic they may not have been functional. The authors propose a hypothesis that involves three developmental phases in the evolution of invertebrate color patterns: (1) the incorporation of metabolic by-products, perhaps some pigmented and some not pigmented, into shells and carapaces as a means of disposal of dietary or metabolic wastes, (2) use of these pigments and patterns as an environmental adaptation, such as light screening, and (3) display during and following the evolution of vision in predators sufficiently sophisticated to see the patterns.

High Origin of Radial Arteries: A Report of Two Rare Cases

Directory of Open Access Journals (Sweden)

Dong Zhan

2010-01-01

Full Text Available Variations in the arterial supply of the upper limb are relatively common, with reported prevalence rates ranging from 11 to 24.4%. Of these, the most commonly encountered variation in the arm is a high origin of the radial artery. However, after consecutively dissecting and examining 600 Singaporean Chinese cadavers (1,200 upper limbs, we found only two cases of this. In both cases, the brachioradial artery originated from the upper one-third of the brachial artery and continued distally as the radial artery in the forearm. The local prevalence of 0.33% of this variation is significantly lower compared against populations from other geographical regions. Although rare, recognition of the variation is of fundamental importance to clinical practice.

[Development of Inhalable Dry Powder Formulations Loaded with Nanoparticles Maintaining Their Original Physical Properties and Functions].

Okuda, Tomoyuki

2017-01-01

 Functional nanoparticles, such as liposomes and polymeric micelles, are attractive drug delivery systems for solubilization, stabilization, sustained release, prolonged tissue retention, and tissue targeting of various encapsulated drugs. For their clinical application in therapy for pulmonary diseases, the development of dry powder inhalation (DPI) formulations is considered practical due to such advantages as: (1) it is noninvasive and can be directly delivered into the lungs; (2) there are few biocomponents in the lungs that interact with nanoparticles; and (3) it shows high storage stability in the solid state against aggregation or precipitation of nanoparticles in water. However, in order to produce effective nanoparticle-loaded dry powders for inhalation, it is essential to pursue an innovative and comprehensive formulation strategy in relation to composition and powderization which can achieve (1) the particle design of dry powders with physical properties suitable for pulmonary delivery through inhalation, and (2) the effective reconstitution of nanoparticles that will maintain their original physical properties and functions after dissolution of the powders. Spray-freeze drying (SFD) is a relatively new powderization technique combining atomization and lyophilization, which can easily produce highly porous dry powders from an aqueous sample solution. Previously, we advanced the optimization of components and process conditions for the production of SFD powders suitable to DPI application. This review describes our recent results in the development of novel DPI formulations effectively loaded with various nanoparticles (electrostatic nanocomplexes for gene therapy, liposomes, and self-assembled lipid nanoparticles), based on SFD.

Dyson, Rodger W (Inventor)

2015-01-01

A flow diode configured to permit fluid flow in a first direction while preventing fluid flow in a second direction opposite the first direction is disclosed. The flow diode prevents fluid flow without use of mechanical closures or moving parts. The flow diode utilizes a bypass flowline whereby all fluid flow in the second direction moves into the bypass flowline having a plurality of tortuous portions providing high fluidic resistance. The portions decrease in diameter such that debris in the fluid is trapped. As fluid only travels in one direction through the portions, the debris remains trapped in the portions.

Drug screens based on the newly found role of dystroglycan proteolysis and restoration of dystroglycan function thereof

Science.gov (United States)

Bissell, Mina J.; Muschler, John L.

2010-02-23

The present invention provides methods and compositions for the diagnosis and treatment of cells lacking normal growth arresting characteristic. The present invention demonstrates that many tumor cells lack normal cell surface .alpha.-dystroglycan and thereby lack dystroglycan function. Dystroglycan can be lost from the cell surface by proteolytic shedding of a fragment of .alpha.-dystroglycan into the surrounding medium. Upon restoration of dystroglycan function and over-expression of the dystroglycan gene, the once tumorigenic cells revert to non-tumorigenic cells which polarize and arrest cell growth in the presence of basement membrane proteins, demonstrating that dystroglycan functions as a tumor marker and suppressor.

Singapore: The Politics of Inventing National Identity

Directory of Open Access Journals (Sweden)

Stephan Ortmann

2009-01-01

Full Text Available This study wants to shed new light on the politics of Singapore’s national identity invention. Since independence in 1965, the Singaporean government has tried to generate a sense of national identity in Singapore. While at first, the priority was on pragmatic values to promote the economic development, this changed in the late 1980s when the government became concerned with the widespread materialism within the society. As an alternative, so-called Asian values sought to provide an ideological alternative and a new basis for a stronger national identity. At the same time, average Singaporeans have developed their own unique conceptions of the city-state’s national identity, which sometimes contradict the official nation-building efforts and thus constitute a subtle form of opposition. Many Singaporeans demand greater participation in the negotiation of their Singaporean identity, which demonstrates the difficulty of constructing a sustainable authoritarian civic national identity.

Functional and evolutionary analysis of alternatively spliced genes is consistent with an early eukaryotic origin of alternative splicing

Directory of Open Access Journals (Sweden)

Penny David

2007-10-01

Full Text Available Abstract Background Alternative splicing has been reported in various eukaryotic groups including plants, apicomplexans, diatoms, amoebae, animals and fungi. However, whether widespread alternative splicing has evolved independently in the different eukaryotic groups or was inherited from their last common ancestor, and may therefore predate multicellularity, is still unknown. To better understand the origin and evolution of alternative splicing and its usage in diverse organisms, we studied alternative splicing in 12 eukaryotic species, comparing rates of alternative splicing across genes of different functional classes, cellular locations, intron/exon structures and evolutionary origins. Results For each species, we find that genes from most functional categories are alternatively spliced. Ancient genes (shared between animals, fungi and plants show high levels of alternative splicing. Genes with products expressed in the nucleus or plasma membrane are generally more alternatively spliced while those expressed in extracellular location show less alternative splicing. We find a clear correspondence between incidence of alternative splicing and intron number per gene both within and between genomes. In general, we find several similarities in patterns of alternative splicing across these diverse eukaryotes. Conclusion Along with previous studies indicating intron-rich genes with weak intron boundary consensus and complex spliceosomes in ancestral organisms, our results suggest that at least a simple form of alternative splicing may already have been present in the unicellular ancestor of plants, fungi and animals. A role for alternative splicing in the evolution of multicellularity then would largely have arisen by co-opting the preexisting process.

Metal–Organic Framework-Functionalized Alumina Membranes for Vacuum Membrane Distillation

Directory of Open Access Journals (Sweden)

Jian Zuo

2016-12-01

Full Text Available Nature-mimetic hydrophobic membranes with high wetting resistance have been designed for seawater desalination via vacuum membrane distillation (VMD in this study. This is achieved through molecular engineering of metal–organic framework (MOF-functionalized alumina surfaces. A two-step synthetic strategy was invented to design the hydrophobic membranes: (1 to intergrow MOF crystals on the alumina tube substrate and (2 to introduce perfluoro molecules onto the MOF functionalized membrane surface. With the first step, the surface morphology, especially the hierarchical roughness, can be controlled by tuning the MOF crystal structure. After the second step, the perfluoro molecules function as an ultrathin layer of hydrophobic floss, which lowers the surface energy. Therefore, the resultant membranes do not only possess the intrinsic advantages of alumina supports such as high stability and high water permeability, but also have a hydrophobic surface formed by MOF functionalization. The membrane prepared under an optimum condition achieved a good VMD flux of 32.3 L/m2-h at 60 °C. This study may open up a totally new approach for design of next-generation high performance membrane distillation membranes for seawater desalination.

The myth of DSM's invention of new categories of disorder: Houts's diagnostic discontinuity thesis disconfirmed.

Science.gov (United States)

Wakefield, J C

2001-05-01

Houts (2001) argues that increases in DSM diagnostic categories are due to the invention of new disorders that are discontinuous with old conceptions of disorder and would not have been previously diagnosed. He maintains that DSM category increases are not comparable in nature to ICD category increases, which are mainly refinements of recognized disorders. I survey categories of disorder introduced after DSM-II and assess whether they are discontinuous with old concepts and categories of disorder. Candidate categories are identified from: Houts and Follette (1998), Mentalism, mechanisms, and medical analogues: Reply to Wakefield. Journal of Consulting and Clinical Psychology; Kutchins and Kirk (1997) Making us crazy: DSM: The psychiatric bible and the creation of mental disorders. New York: Free Press; and my own list. The result is that virtually none of the candidate categories are invented, discontinuous categories. In almost every case, the newly labeled conditions were considered disorders at the time of DSM-II and would have been diagnosed under DSM-II categories. I also reexamine DSM-IV sleep disorder categories, which Houts claims are discontinuous with past diagnostic conceptions. The result is that all DSM-IV sleep disorders were recognized as disorders at the time of DSM-II, and most were recognized as mental disorders. I conclude that DSM category increases are comparable in nature to ICD category increases, and that the invention-of-disorder account cannot explain the vast majority of such increases.

Ratings of speed in real music as a function of both original and manipulated beat tempo.

Science.gov (United States)

Madison, Guy; Paulin, Johan

2010-11-01

There is an apparent contradiction between the narrow range of tempi optimal for perceptual judgment and motor synchronization and the wide range of beat tempi found in real music. The relation between listeners' perception of speed and beat tempo was therefore investigated, both for real music excerpts (ME) and metronome sequences. Tempi ranged from 42 to 200 beats per minute (BPM), and some excerpts were further tempo manipulated in four levels from ±5 to ±20%. Regression analyses showed that speed was a shallower function of original tempo for fast (>150 BPM) and slow (tempo had twice as large an effect on speed as had original tempo. In contrast, speed was an almost linear function of tempo for metronome sequences. Taken together, these results show that the non-linearity stems from properties of the musical signal, rather than being a subjective perceptual effect. They indicate an inverse relation between tempo and relative event density in real music, and demonstrate that the perception of periodic signals is affected not only by the beat level, but also by faster and slower levels.

Evolutionary origins and functions of the carotenoid biosynthetic pathway in marine diatoms.

Directory of Open Access Journals (Sweden)

Sacha Coesel

Full Text Available Carotenoids are produced by all photosynthetic organisms, where they play essential roles in light harvesting and photoprotection. The carotenoid biosynthetic pathway of diatoms is largely unstudied, but is of particular interest because these organisms have a very different evolutionary history with respect to the Plantae and are thought to be derived from an ancient secondary endosymbiosis between heterotrophic and autotrophic eukaryotes. Furthermore, diatoms have an additional xanthophyll-based cycle for dissipating excess light energy with respect to green algae and higher plants. To explore the origins and functions of the carotenoid pathway in diatoms we searched for genes encoding pathway components in the recently completed genome sequences of two marine diatoms. Consistent with the supplemental xanthophyll cycle in diatoms, we found more copies of the genes encoding violaxanthin de-epoxidase (VDE and zeaxanthin epoxidase (ZEP enzymes compared with other photosynthetic eukaryotes. However, the similarity of these enzymes with those of higher plants indicates that they had very probably diversified before the secondary endosymbiosis had occurred, implying that VDE and ZEP represent early eukaryotic innovations in the Plantae. Consequently, the diatom chromist lineage likely obtained all paralogues of ZEP and VDE genes during the process of secondary endosymbiosis by gene transfer from the nucleus of the algal endosymbiont to the host nucleus. Furthermore, the presence of a ZEP gene in Tetrahymena thermophila provides the first evidence for a secondary plastid gene encoded in a heterotrophic ciliate, providing support for the chromalveolate hypothesis. Protein domain structures and expression analyses in the pennate diatom Phaeodactylum tricornutum indicate diverse roles for the different ZEP and VDE isoforms and demonstrate that they are differentially regulated by light. These studies therefore reveal the ancient origins of several

Evolutionary origin and function of NOX4-art, an arthropod specific NADPH oxidase.

Science.gov (United States)

Gandara, Ana Caroline Paiva; Torres, André; Bahia, Ana Cristina; Oliveira, Pedro L; Schama, Renata

2017-03-29

NADPH oxidases (NOX) are ROS producing enzymes that perform essential roles in cell physiology, including cell signaling and antimicrobial defense. This gene family is present in most eukaryotes, suggesting a common ancestor. To date, only a limited number of phylogenetic studies of metazoan NOXes have been performed, with few arthropod genes. In arthropods, only NOX5 and DUOX genes have been found and a gene called NOXm was found in mosquitoes but its origin and function has not been examined. In this study, we analyzed the evolution of this gene family in arthropods. A thorough search of genomes and transcriptomes was performed enabling us to browse most branches of arthropod phylogeny. We have found that the subfamilies NOX5 and DUOX are present in all arthropod groups. We also show that a NOX gene, closely related to NOX4 and previously found only in mosquitoes (NOXm), can also be found in other taxonomic groups, leading us to rename it as NOX4-art. Although the accessory protein p22-phox, essential for NOX1-4 activation, was not found in any of the arthropods studied, NOX4-art of Aedes aegypti encodes an active protein that produces H 2 O 2 . Although NOX4-art has been lost in a number of arthropod lineages, it has all the domains and many signature residues and motifs necessary for ROS production and, when silenced, H 2 O 2 production is considerably diminished in A. aegypti cells. Combining all bioinformatic analyses and laboratory work we have reached interesting conclusions regarding arthropod NOX gene family evolution. NOX5 and DUOX are present in all arthropod lineages but it seems that a NOX2-like gene was lost in the ancestral lineage leading to Ecdysozoa. The NOX4-art gene originated from a NOX4-like ancestor and is functional. Although no p22-phox was observed in arthropods, there was no evidence of neo-functionalization and this gene probably produces H 2 O 2 as in other metazoan NOX4 genes. Although functional and present in the genomes of many

BUZZWORDS IN MODERN RUSSIAN AND CHINESE NEWSPAPERS: ORIGIN, SEMANTICS, FUNCTIONS

Directory of Open Access Journals (Sweden)

- Чэнь Хуань

2017-12-01

Full Text Available Fashion exists in all aspects of human life, including language. In this context, we refer to the phenomenon of language fashion, which became an object of linguistic study in Russia at the turn of the 20th/21st centuries. This article is concerned with the phenomenon of buzzwords in modern Russian and Chinese newspaper texts, from the perspective of comparative analysis. In the article, we clarify the meanings of language fashion and buzzwords, discuss the essential features of this linguistic phenomenon, present a classification of buzzwords, characterise the main ways of enlarging this group of lexical units, and analyse the semantic and functional features of these units. The material for analysis is drawn from newspaper texts in online versions of Russian and Chinese mass media resources, for the period 2016-2017. The results of the research show that there are common features between the buzzwords of the two languages. Firstly, from the point of view of origin, the form or meaning of the buzzwords is associated with novelty and a break with tradition. Secondly, in a semantic sense, there are lexical coincidences in the buzzwords of the two languages. Thirdly, in a functional sense, a buzzword in one or another language can act as a pro-ductive model for creating new words, and a stimulus for the realization of new ideas. The conclusion dis-cusses the prospects of studying buzzwords and language fashion in general.

SGLT1-mediated transport in Caco-2 cells is highly dependent on cell bank origin

DEFF Research Database (Denmark)

Steffansen, B; Pedersen, Maria; Laghmoch, A M

2017-01-01

The Caco-2 cell line is a well-established in vitro model for studying transport phenomena for prediction of intestinal nutrient and drug absorption. However, for substances depending on transporters such predictions are complicated due to variable transporter expression and limited knowledge about...... transporter function during multiple cell passaging and cell thawings. In the case of SGLT1, a key transporter of oral absorption of D-glucose, one reason for compromised prediction could be inadequate expression of SGLT1 in Caco-2 cells and thereby limited sensitivity in the determination of SGLT1-mediated...... permeability (PSGLT1). Here, the objective was to characterize and compare SGLT1-mediated uptake in Caco-2 cells obtained from different cell banks. SGLT1-mediated uptake of the standard SGLT1 substrate, α-MDG, in Caco-2 cells was shown to be highly dependent on cell bank origin. The most robust and reliable...

Gaze recognition in high-functioning autistic patients. Evidence from functional MRI

International Nuclear Information System (INIS)

Takebayashi, Hiroko; Ogai, Masahiro; Matsumoto, Hideo

2006-01-01

We examined whether patients with high-functioning autistic disorder (AD) would exhibit abnormal activation in brain regions implicated in the functioning of theory of mind (TOM) during gaze recognition. We investigated brain activity during gaze recognition in 5 patients with high-functioning AD and 9 normal subjects, using functional magnetic resonance imaging. On the gaze task, more activation was found in the left middle frontal gyrus, the right intraparietal sulcus, and the precentral and inferior parietal gyri bilaterally in controls than in AD patients, whereas the patient group showed more powerful signal changes in the left superior temporal gyrus, the right insula, and the right medial frontal gyrus. These results suggest that high-functioning AD patients have functional abnormalities not only in TOM-related brain regions, but also in widely distributed brain regions that are not normally activated upon the processing of information from another person's gaze.

Fundamental Issues Related to the Origin of Melatonin and Melatonin Isomers during Evolution: Relation to Their Biological Functions

Directory of Open Access Journals (Sweden)

Dun-Xian Tan

2014-09-01

Full Text Available Melatonin and melatonin isomers exist and/or coexist in living organisms including yeasts, bacteria and plants. The levels of melatonin isomers are significantly higher than that of melatonin in some plants and in several fermented products such as in wine and bread. Currently, there are no reports documenting the presence of melatonin isomers in vertebrates. From an evolutionary point of view, it is unlikely that melatonin isomers do not exist in vertebrates. On the other hand, large quantities of the microbial flora exist in the gut of the vertebrates. These microorganisms frequently exchange materials with the host. Melatonin isomers, which are produced by these organisms inevitably enter the host’s system. The origins of melatonin and its isomers can be traced back to photosynthetic bacteria and other primitive unicellular organisms. Since some of these bacteria are believed to be the precursors of mitochondria and chloroplasts these cellular organelles may be the primary sites of melatonin production in animals or in plants, respectively. Phylogenic analysis based on its rate-limiting synthetic enzyme, serotonin N-acetyltransferase (SNAT, indicates its multiple origins during evolution. Therefore, it is likely that melatonin and its isomer are also present in the domain of archaea, which perhaps require these molecules to protect them against hostile environments including extremely high or low temperature. Evidence indicates that the initial and primary function of melatonin and its isomers was to serve as the first-line of defence against oxidative stress and all other functions were acquired during evolution either by the process of adoption or by the extension of its antioxidative capacity.

Origin and concept of medicine food homology and its application in modern functional foods.

Science.gov (United States)

Hou, Yan; Jiang, Jian-Guo

2013-12-01

The viewpoints of "medicine food homology" (MFH) conform to today's food requirements of returning to a natural and green healthy life. This paper aims to introduce the concept of MFH and its origin and evolution, and analyze the relationship between food and Chinese medicine. In this review, more than 80 MFH materials approved by China's Ministry of Health are listed and their effective ingredients are summarized in detail. Their treatment mechanism in TCM and western medicine are summarized too. Moreover, some new MFH resources that have been gradually developed are also introduced. MFH materials are a treasure house of functional factors for current functional foods. Innovative ideas for the development of MFH resources in current functional foods are prospected and discussed, such as taking advantage of Chinese diet theory, building a database for MFH varieties and developing new methods and technologies. At present, modern research for the development of MFH functional foods is still in its primary stage, there is still much work required in the popularization of the MFH concept and the development of new products. Knowledge and technological innovations in this area should be accelerated in the future to promote the modernization of MFH.

Origin of secretin receptor precedes the advent of tetrapoda: evidence on the separated origins of secretin and orexin.

Directory of Open Access Journals (Sweden)

Janice K V Tam

Full Text Available At present, secretin and its receptor have only been identified in mammals, and the origin of this ligand-receptor pair in early vertebrates is unclear. In addition, the elusive similarities of secretin and orexin in terms of both structures and functions suggest a common ancestral origin early in the vertebrate lineage. In this article, with the cloning and functional characterization of secretin receptors from lungfish and X. laevis as well as frog (X. laevis and Rana rugulosa secretins, we provide evidence that the secretin ligand-receptor pair has already diverged and become highly specific by the emergence of tetrapods. The secretin receptor-like sequence cloned from lungfish indicates that the secretin receptor was descended from a VPAC-like receptor prior the advent of sarcopterygians. To clarify the controversial relationship of secretin and orexin, orexin type-2 receptor was cloned from X. laevis. We demonstrated that, in frog, secretin and orexin could activate their mutual receptors, indicating their coordinated complementary role in mediating physiological processes in non-mammalian vertebrates. However, among the peptides in the secretin/glucagon superfamily, secretin was found to be the only peptide that could activate the orexin receptor. We therefore hypothesize that secretin and orexin are of different ancestral origins early in the vertebrate lineage.

Origin of a bottom-heavy stellar initial mass function in elliptical galaxies

International Nuclear Information System (INIS)

Bekki, Kenji

2013-01-01

We investigate the origin of a bottom-heavy stellar initial mass function (IMF) recently observed in elliptical galaxies by using chemical evolution models with a non-universal IMF. We adopt the variable Kroupa IMF with the three slopes (α 1 , α 2 , and α 3 ) dependent on metallicities ([Fe/H]) and densities (ρ g ) of star-forming gas clouds and thereby search for the best IMF model that can reproduce (1) the observed steep IMF slope (α 2 ∼ 3, i.e., bottom-heavy) for low stellar masses (m ≤ 1 M ☉ ) and (2) the correlation of α 2 with chemical properties of elliptical galaxies in a self-consistent manner. We find that if the IMF slope α 2 depends on both [Fe/H] and ρ g , then elliptical galaxies with higher [Mg/Fe] can have steeper α 2 (∼3) in our models. We also find that the observed positive correlation of stellar mass-to-light ratios (M/L) with [Mg/Fe] in elliptical galaxies can be quantitatively reproduced in our models with α 2 ∝β[Fe/H] + γlog ρ g , where β ∼ 0.5 and γ ∼ 2. We discuss whether the IMF slopes for low-mass (α 2 ) and high-mass stars (α 3 ) need to vary independently from each other to explain a number of IMF-related observational results self-consistently. We also briefly discuss why α 2 depends differently on [Fe/H] in dwarf and giant elliptical galaxies.

2001-01-01

The present invention relates generally to mesoporous sorbent materials having high capacity, high selectivity, fast kinetics, and molecular recognition capability. The invention also relates to a process for preparing these mesoporous substrates through molecular imprinting techniques which differ from convention techniques in that a template molecule is bound to one end of bifunctional ligands to form a complex prior to binding of the bifunctional ligands to the substrate. The present invention also relates to methods of using the mesoporous sorbent materials, for example, in the separation of toxic metals from process effluents, paints, and other samples; detection of target molecules, such as amino acids, drugs, herbicides, fertilizers, and TNT, in samples; separation and/or detection of substances using chromatography; imaging agents; sensors; coatings; and composites.

Patents on inventions related to human embryonic stem cells: the morality clause after Brüstle v. Greenpeace.

Science.gov (United States)

Panis, Sarah

2013-09-01

This paper analyses the meaning of Article 6, para. 2, sub c of the Biotechnology Directive prohibiting patents on inventions using human embryos for industrial or commercial purposes. It first examines the evolution ofthe Court of Justice ofthe EU's interpretation of this provision (which is part of the morality clause) and focuses on its most recent decision, Brüstle v. Greenpeace. This is considered a landmark case for three reasons: firstly, because it defines for the first time the term "embryo" in patent law; secondly, because it is the Court of Justice (and not EPO) that ruled on patent law; the third reason is its very broad interpretation of the morality exclusion. The exclusion is no longer limited to embryos but is extended to (even banked) embryonic stem cells and all downstream products made with them. It then looks into the consequences for the patentability of inventions using cells derived from human embryonic stem cells, such as Brüstle's invention. The recent decision by Germany's Federal Court of Justice on the validity of Brüstle's patent emphasises the limited influence on the patentability of those inventions. After that, the paper addresses possible cuts in funding stem cell research and even legislative bans of this type of research. This is followed by an evaluation of the existence and content of the morality exclusion. After a comparative analysis with the US, which is lacking in such morality exclusion, the paper concludes that the morality clause as a whole paid its dues but the provision on the use of human embryos is questionable as there is no European consensus against the use of human embryos for industrial or commercial purposes.

The invention describes a new class of highly stable mixed conducting materials based on acceptor doped cerium oxide (CeO2-8 ) in which the limiting electronic conductivity is significantly enhanced by co-doping with a second element or co- dopant, such as Nb, W and Zn, so that cerium and the co......-dopant have an ionic size ratio between 0.5 and 1. These materials can thereby improve the performance and extend the range of operating conditions of oxygen permeation membranes (OPM) for different high temperature membrane reactor applications. The invention also relates to the manufacturing of supported...

Inventions leading to the development of the diagnostic test kit industry--from the modern pregnancy test to the sandwich assays.

Wide, Leif

The universities are encouraged by the government nowadays to stimulate innovations and also to provide the proper machinery for assisting the protection and commercialisation of innovations. A better understanding of the innovation process may help to create an atmosphere suitable for inventions at the university. Examples can be taken from successful innovations previously made at the university. During the 1960's I made a series of inventions, which ultimately led to the development of the diagnostic test kit industry. The first, which I made as an undergraduate, was a simple and reliable test kit for diagnosis of pregnancy. This was followed by the solid phase radioimmunoassay and a solid phase assay for vitamin B12; next, the dual specific non-competitive sandwich assay and the in-vitro test for diagnosis of allergy, called RAST (Radioallergosorbent test). Organon in Holland with the pregnancy test kit, and Pharmacia in Sweden with test kits for radioimmunoassay, became pioneers among the diagnostic test kit industries. Pharmacia Diagnostics later became one of the leading diagnostic test kit companies in the world and has continued to be so in the field of allergy diagnosis. Each one of these inventions started with a few unique observations leading to a technical development. The pregnancy test as well as the allergy test emerged from the development of assay methods with unique qualities with the subsequent search for appropriate applications. The foreseeing of a commercial value on a future market was a very important step. This was followed by the search for a suitable industry interested to exploit the invention with its new business opportunity i.e. apply for a patent, produce and market the products, which in my case consisted of the necessary reagents and equipments for particular diagnostic tests. Finally, an agreement had to be settled between the entrepreneur and the inventors. This report describes these inventions and particularly discusses some

Wallace H. Coulter: decades of invention and discovery.

Science.gov (United States)

Robinson, J Paul

2013-05-01

Only a few inventors can be said to have made as great an impact on mankind as Wallace Coulter. His inquisitive mind and ability to see well beyond what existed served him well for 40 years of inventing. So many of the fundamental tools that exist today in the area of hematology were derived from or driven by Coulter's inventions that he could be called the most technological innovator in the field of modern hematology. In achieving these discoveries Wallace Coulter was clearly capable of visualizing future opportunities that few others recognized. His vision was combined with an uncanny ability to translate his ideas into products. He developed a large number of tools that shaped the fields of cytometry, image analysis, and industrial materials. His understanding of the future power of computation drove him to link these technologies in a unique way. In the end, Coulter shaped the technologies that ultimately drove hematology in a new direction, one that remains on a critical pathway linking technology innovation all the way to true translational impact. It was said of Henry Ford that "[h]e has no notion that wealth has made him great, and any one who is imprest merely by his wealth bores him. In his personal contacts he likes to dodge the subject. He would prefer to talk with a machinist about machinery, or with somebody who likes birds about birds. In these contacts, he asks no deference; and if he gets it, he suspects it is mere deference to wealth, and that ends his interest."(1) The same could be said of Wallace Coulter, who, like Ford, understood the concepts of mass production and customer service. Coulter had the ability to recognize the opportunity and fulfill the need for development of a blood-cell counter that could be placed in every pathology laboratory, and in so doing transformed a field from a qualitative to a quantitative environment. Every person who has ever entered a medical lab, hospital, or doctor's office has felt the impact of Coulter

The Historical Origins and Economic Logic of 'Open Science'

CERN Multimedia

CERN. Geneva

2008-01-01

Modern "big science" projects, such as the LHC experiments in physics that are being prepared to run at CERN, embody the distinctive ethos of cooperation and mechanisms of coordination among distributed groups of researchers that are characteristic of 'open science'. Much has been written about the institutions of open science, their supporting social norms, and their effectiveness in generating additions to the stock of reliable knowledge. But from where have these institutions and their supporting ethos come? How robust can we assume them to be in the face of the recent trends for universities and research institutes in some domains of science to seek to appropriate the benefits of new discoveries and inventions by asserting intellectual property claims? A search for the historical origins of the institutions of open science throws some new light on these issues, and the answers may offer some lessons for contemporary science and technology policy-making.

In my paper I want to focus on the social constructivists and their approach of using technology to define (constructed) reality. Based on this, constructivists argue that technology can be a means to define social roles. Furthermore, I want to analyze this theory on the practical example of the photographs of women in different phases of hysteria, based on Georges Didi-Huberman’s book Invention of Hysteria (1982)

Supervised Classification High-Resolution Remote-Sensing Image Based on Interval Type-2 Fuzzy Membership Function

Directory of Open Access Journals (Sweden)

Chunyan Wang

2018-05-01

Full Text Available Because of the degradation of classification accuracy that is caused by the uncertainty of pixel class and classification decisions of high-resolution remote-sensing images, we proposed a supervised classification method that is based on an interval type-2 fuzzy membership function for high-resolution remote-sensing images. We analyze the data features of a high-resolution remote-sensing image and construct a type-1 membership function model in a homogenous region by supervised sampling in order to characterize the uncertainty of the pixel class. On the basis of the fuzzy membership function model in the homogeneous region and in accordance with the 3σ criterion of normal distribution, we proposed a method for modeling three types of interval type-2 membership functions and analyze the different types of functions to improve the uncertainty of pixel class expressed by the type-1 fuzzy membership function and to enhance the accuracy of classification decision. According to the principle that importance will increase with a decrease in the distance between the original, upper, and lower fuzzy membership of the training data and the corresponding frequency value in the histogram, we use the weighted average sum of three types of fuzzy membership as the new fuzzy membership of the pixel to be classified and then integrated into the neighborhood pixel relations, constructing a classification decision model. We use the proposed method to classify real high-resolution remote-sensing images and synthetic images. Additionally, we qualitatively and quantitatively evaluate the test results. The results show that a higher classification accuracy can be achieved with the proposed algorithm.

Two-body Dirac equation and its wave function at the origin

International Nuclear Information System (INIS)

Ito, Hitoshi

1998-01-01

We propose a relativistic bound state equation for the Dirac particles interacting through an Abelian gauge field. It reduces to the (one body) Dirac equation in the infinite limit of one of the masses and is invariant under the PCT transformation. This invariance is a consequence of a modification of the Stueckelberg-Feynman boundary condition for propagation of the negative-energy two-body states, by which the some effect of the crossed diagram is taken in the lowest ladder equation. We can correct back the modification in perturbative calculations of the weak-coupling theory by adding a counter correction term in the interaction kernel. The equation can be used for the phenomenology of the heavy flavored mesons. We get good behavior of the wave function at the origin (WFO), with which the annihilation amplitude of the pseudoscalar meson becomes finite. Some comments are mentioned for the application in the heavy quark effective theory. The talk was based on a preprint

Definition of chronic kidney disease and measurement of kidney function in original research papers: a review of the literature.

Science.gov (United States)

Anderson, Jocelyn; Glynn, Liam G

2011-09-01

Over the past decade, chronic kidney disease (CKD) has become an area of intensive clinical and epidemiological research. Despite the clarity provided by the Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines, there appears to be within the CKD research literature significant disagreement on how to define CKD and measure kidney function. The objectives of this study were to investigate the variety of methods used to define CKD and to measure kidney function in original research papers as well as to investigate whether the quality of the journal had any effect on the quality of the methodology used. This was a descriptive review and not a meta-analysis. Information was extracted from each article including publication details (including the journal's impact factor), definition of CKD, method used to estimate kidney function and quantity of serum creatinine readings used to define CKD. An electronic search of MEDLINE through OVID was completed using the search term CKD. The search was limited to articles in English published in 2009. Studies were included in the review only if they were original research articles including patients with CKD. Articles were excluded if they reported data from a paediatric population, a population solely on dialysis or if there was no full-text access through OVID. Each article was assessed for quality with respect to using KDOQI CKD definition criteria. A description of the pooled data was completed and chi-square tests were used to investigate the relation between article quality and journal quality. Analysis was carried out using SPSS (15.0) and a P-value of definitions are being used in original research articles to define CKD and measure kidney function which calls into question the validity and reliability of such research findings and associated clinical guidelines. International consensus is urgently required to improve validity and generalizability of CKD research findings.

The present invention provides new methods for the in vitro preparation of bioartificial tissue equivalents and their enhanced integration after implantation in vivo. These methods include submitting a tissue construct to a biomimetic electrical stimulation during cultivation in vitro to improve its structural and functional properties, and/or in vivo, after implantation of the construct, to enhance its integration with host tissue and increase cell survival and functionality. The inventive methods are particularly useful for the production of bioartificial equivalents and/or the repair and replacement of native tissues that contain electrically excitable cells and are subject to electrical stimulation in vivo, such as, for example, cardiac muscle tissue, striated skeletal muscle tissue, smooth muscle tissue, bone, vasculature, and nerve tissue.

Domain-specificity of creativity: a study on the relationship between Visual Creativity and Visual Mental Imagery’.

Directory of Open Access Journals (Sweden)

Massimiliano ePalmiero

2015-12-01

Full Text Available Creativity refers to the capability to catch original and valuable ideas and solutions. It involves different processes. In this study the extent to which visual creativity is related to cognitive processes underlying visual mental imagery was investigated. Fifty college students (25 women carried out: the Creative Synthesis Task, which measures the ability to produce creative objects belonging to a given category (originality, synthesis and transformation scores of pre-inventive forms, and originality and practicality scores of inventions were computed; an adaptation of Clark’s Drawing Ability Test, which measures the ability to produce actual creative artworks (graphic ability, aesthetic and creativity scores of drawings were assessed and three mental imagery tasks that investigate the three main cognitive processes involved in visual mental imagery: generation, inspection and transformation. Vividness of imagery and verbalizer-visualizer cognitive style were also measured using questionnaires. Correlation analysis revealed that all measures of the creativity tasks positively correlated with the image transformation imagery ability; practicality of inventions negatively correlated with vividness of imagery; originality of inventions positively correlated with the visualization cognitive style. However, regression analysis confirmed the predictive role of the transformation imagery ability only for the originality score of inventions and for the graphic ability and aesthetic scores of artistic drawings; on the other hand, the visualization cognitive style predicted the originality of inventions, whereas the vividness of imagery predicted practicality of inventions. These results are consistent with the notion that visual creativity is domain- and task-specific.

From Hallucination to Fiction: The Invention of Meaning in Psychosis.

Science.gov (United States)

Lippi, Silvia; Lehaire, Célia; Petit, Laetitia

2016-12-01

Taking their inspiration from a case history, the authors explore the effects of a writing workshop led by a professional writer for patients in a psychiatric hospital. This workshop allowed different modes of transference to unfold: transference to the analyst-therapist, transference to the writer who led the workshop, and transference to the other members of the group. The writing activity created conditions in which there could be a movement from hallucination to delusion-a delusion expressed in fiction through the act of writing. Psychotic patients "invent" a writing that remains unfinished and that relates to the experiences of persecution. Writing thus makes it possible for them to tolerate language, through its transformation into writing.

4,300-year-old chimpanzee sites and the origins of percussive stone technology.

2007-02-27

Archaeological research in the African rainforest reveals unexpected results in the search for the origins of hominoid technology. The ancient Panin sites from Côte d'Ivoire constitute the only evidence of prehistoric ape behavior known to date anywhere in the world. Recent archaeological work has yielded behaviorally modified stones, dated by chronometric means to 4,300 years of age, lodging starch residue suggestive of prehistoric dietary practices by ancient chimpanzees. The "Chimpanzee Stone Age" pre-dates the advent of settled farming villages in this part of the African rainforest and suggests that percussive material culture could have been inherited from an common human-chimpanzee clade, rather than invented by hominins, or have arisen by imitation, or resulted from independent technological convergence.

High-Resolution Profiling of Drosophila Replication Start Sites Reveals a DNA Shape and Chromatin Signature of Metazoan Origins

Directory of Open Access Journals (Sweden)

Federico Comoglio

2015-05-01

Full Text Available At every cell cycle, faithful inheritance of metazoan genomes requires the concerted activation of thousands of DNA replication origins. However, the genetic and chromatin features defining metazoan replication start sites remain largely unknown. Here, we delineate the origin repertoire of the Drosophila genome at high resolution. We address the role of origin-proximal G-quadruplexes and suggest that they transiently stall replication forks in vivo. We dissect the chromatin configuration of replication origins and identify a rich spatial organization of chromatin features at initiation sites. DNA shape and chromatin configurations, not strict sequence motifs, mark and predict origins in higher eukaryotes. We further examine the link between transcription and origin firing and reveal that modulation of origin activity across cell types is intimately linked to cell-type-specific transcriptional programs. Our study unravels conserved origin features and provides unique insights into the relationship among DNA topology, chromatin, transcription, and replication initiation across metazoa.

The Effects of Instruction of Creative Invention on Students' Situational Interest in Physics Lesson

Science.gov (United States)

Leung, Tim

There are a few empirical studies (Palmer, 2008; Dohn, 2010) or intervention programs (Hidi & Harackiewicz, 2000) about students' situational interest in physics lessons, although the declining interest in physics among students has been well documented in the research literature (Gardner, 1998 ; International Bureau for Education, 2001; European Commission, 2007; Oon & Subramaniam, 2011). Even in the research area of science education, yet little is known about how to trigger students' catching and holding situational interest in a physics lesson. In this study, five intervention lessons of creative invention were developed. Each lesson consists of three parts including Eberle's (1971, 1972) SCAMPER technique on the creative thinking, knowledge and concepts of physics curriculum, hands-on activities related to both SCAMPER technique and physics concepts. Two surveys were developed and used to measure the situational interest and individual interest of students in physics lessons. Qualitative conversational interviews were used to interpret the sources of situational interest of students in physics lessons. Results in this study indicate that new inventive products and television programs or films related to SCAMPER can trigger the catching interest in physics lessons. Meaningful hands-on activities related to both SCAMPER technique and physics concepts can trigger the holding interest in physics lessons. There is no significant difference in situational interest among students with different academic abilities except in the topic related to electronic components. The students with lower academic ability have greater situational interest than the students with higher academic ability in learning the topic related to electronic components. There is no significant difference in situational interest between boys and girls except in the topic related to revolving paper lantern. Girls have higher situational interest than boys in learning the topic related to revolving

lineages. We demonstrate that lineage-specific genes have high tissue specificity and low expression levels across multiple tissues and developmental stages. Finally, stress responsiveness is identified as a distinct feature of Brassicaceae-specific genes; where these LSGs are enriched for genes responsive to a wide range of abiotic stresses. Conclusion Improving our understanding of the origins of lineage-specific genes is key to gaining insights regarding how novel genes can arise and acquire functionality in different lineages. This study comprehensively identifies all of the Brassicaceae-specific genes in Arabidopsis thaliana and identifies how the majority of such lineage-specific genes have arisen. The analysis allows the relative importance (and prevalence) of different evolutionary routes to the genesis of novel ORFs within lineages to be assessed. Insights regarding the functional roles of lineage-specific genes are further advanced through identification of enrichment for stress responsiveness in lineage-specific genes, highlighting their likely importance for environmental adaptation strategies.

Why Is Hard To Patent An Invention?

Directory of Open Access Journals (Sweden)

2007-01-01

Full Text Available When employed by a company, in almost all the cases a new employee has to sign an agreement giving the company exclusive rights to any intellectual property developed as part of their work assignments. This agreement could extend beyond a change of jobs and cause conflict of interests in new employment situations. A patent is a government-granted monopoly given to an inventor as both a reward for the intellectual and financial investment, and a stimulus to innovate. As a monopoly, the patent has legal power to exclude others from exploiting the invention in any way for a period of 20 years from the time the patent application has been filed. A trademark provides instant recognition of a product or company; a service mark provides instant recognition of a service. They both have unlimited lifetime. But the owner must renew or confirm continuous use at the end of five years, and every 10 years thereafter. A trade secret is information keep secret by the owner to give him advantage over competitors. Since it is secret, a trade secret protection has unlimited lifetime.

The Invention of Infertility in the Classical Greek World:

Science.gov (United States)

Flemming, Rebecca

2013-01-01

Summary The article examines the understandings of, and responses to, reproductive failure in the classical Greek world. It discusses explanations and treatments for non-procreation in a range of ancient Greek medical texts, focusing on the writings of the Hippocratic Corpus, which devote considerable energy to matters of fertility and generation, and places them alongside the availability of a divine approach to dealing with reproductive disruption, the possibility of asking various deities, including the specialist healing god Asclepius, for assistance in having children. Though the relations between these options are complex, they combine to produce a rich remedial array for those struggling with childlessness, the possibility that any impediment to procreation can be removed. Classical Greece, rather than the nineteenth century, or even 1978, is thus the time when “infertility,” understood as an essentially reversible somatic state, was invented. PMID:24362276

Peritoneal and mediastinal highly differentiated follicular carcinoma of ovarian origin

2014-01-01

A 70-year-old female patient presented to her primary care doctor with persistent elevated alkaline phosphatase of suspected metastatic etiology. Computed tomography demonstrated epicardial and peritoneal nodules. Biopsy of one of the peritoneal nodules revealed thyroid tissue and extraovarian struma ovarii was considered. The patient had a history of remote total abdominal hysterectomy and bilateral salpingo-oophorectomy 31 years prior for endometriosis with no available pathology from that surgery. The patient recalls being told that she had a left ovarian cyst. A thyroid ultrasound was performed that demonstrated multiple nodules without concerning features; however, due to high clinical suspicion, a total thyroidectomy was performed. Upon full histological evaluation a 0.5 cm papillary microcarcinoma was found. Given the rarity of metastatic papillary cancer to the peritoneum and the small size and grade of the tumor, a diagnosis of highly differentiated follicular carcinoma of ovarian origin was favored. The patient was subsequently treated with radioiodine therapy

The market entry, sales, and employment data presented in this paper suggest that ERIP has been able to efficiently produce positive economic impacts. It is likely that the documented successes of ERIP's inventors will be even greater as their projects mature and more current commercialization information is collected. Survey data presented elsewhere indicate that the ERIP financial support, endorsement, encouragement, and commercialization education are viewed by participants as the most important benefits of the program (Brown, Morell, Snell, Soderstrom, and Friggle, 1987). Other federal, state, and local programs might profit substantially from modelling the composition and delivery of their assistance after the Energy-Related Inventions Program.

I introduce seven criteria for determining the validity of competing theories for the original function of language. I go on to present a novel explanation that meets all the criteria: language originally evolved to teach kin. I suggest that the use of symbols subsequently generated evolutionary feedback at two levels, in the form of self-modified selection pressures that favored structures in the mind that functioned to manipulate and use symbols with efficiency, and cultural selection on languages for learnability.

Herpesvirus papio contains a plasmid origin of replication that acts in cis interspecies with an Epstein-Barr virus trans-acting function.

Pesano, R L; Pagano, J S

1986-01-01

Herpesvirus papio (HVP) and Epstein-Barr virus (EBV) are closely related biologically and biochemically; lymphoblastoid cells infected with either virus contain episomal viral DNA. The putative origin of replication for EBV plasmids (oriP) has been assigned to a 1,790-base-pair fragment (cis) in the short unique region of the genome which requires a viral function supplied in trans from elsewhere in the genome (J. Yates, N. Warren, D. Reisman, and B. Sugden, Proc. Natl. Acad. Sci. USA 81:3806-3810, 1984). We report here the identification of the putative origin of replication (cis) in HVP; we assigned it to the HVP EcoRI K fragment. The results indicate that the HVP replication process requires both a cis and a trans-acting function, analogous to that found in EBV. Images PMID:3023667

It has now been determined that the unique features of the high pressure shock method, especially the shock-induced chemical synthesis technique, are fully applicable to high temperature superconducting materials. Extraordinarily high yields are achievable in accordance with this invention, e.g., generally in the range from about 20% to about 99%, often in the range from about 50% to about 90%, lower and higher yields, of course, also being possible. The method of this invention involves the application of a controlled high pressure shock compression pulse which can be produced in any conventional manner, e.g., by detonation of a high explosive material, the impact of a high speed projectile or the effect of intense pulsed radiation sources such as lasers or electron beams. Examples and a discussion are presented.

The very high energy and the very low flux of these gamma rays, posed numerous detection problems which in turn were the object of a very intense research activity. The present article tries to review the detection techniques for the high energy gamma rays of cosmic origin. In the 'Introduction' we summarize the specific problems involved in the detection of this type of radiation. 'Chapter 1' presents the classic technique based on the use of scintillation detectors. 'Chapter 2' includes the imaging atmospheric Cherenkov technique (IACT) and the sampling wavefront technique. 'Chapter 3' is dedicated to the detection of the atmospheric nitrogen. 'Chapter 4' describes issues related to the calibration of the detectors, the cross checking of the experimental data, the use of the Monte Carlo simulations and the use of the density observed at a distance of 600 m S(600), in order to estimate the primary energy. The characteristics of some future developments of the above presented techniques are included in the last chapter. (authors)

Functional enrichment analyses and construction of functional similarity networks with high confidence function prediction by PFP

Directory of Open Access Journals (Sweden)

Kihara Daisuke

2010-05-01

Full Text Available Abstract Background A new paradigm of biological investigation takes advantage of technologies that produce large high throughput datasets, including genome sequences, interactions of proteins, and gene expression. The ability of biologists to analyze and interpret such data relies on functional annotation of the included proteins, but even in highly characterized organisms many proteins can lack the functional evidence necessary to infer their biological relevance. Results Here we have applied high confidence function predictions from our automated prediction system, PFP, to three genome sequences, Escherichia coli, Saccharomyces cerevisiae, and Plasmodium falciparum (malaria. The number of annotated genes is increased by PFP to over 90% for all of the genomes. Using the large coverage of the function annotation, we introduced the functional similarity networks which represent the functional space of the proteomes. Four different functional similarity networks are constructed for each proteome, one each by considering similarity in a single Gene Ontology (GO category, i.e. Biological Process, Cellular Component, and Molecular Function, and another one by considering overall similarity with the funSim score. The functional similarity networks are shown to have higher modularity than the protein-protein interaction network. Moreover, the funSim score network is distinct from the single GO-score networks by showing a higher clustering degree exponent value and thus has a higher tendency to be hierarchical. In addition, examining function assignments to the protein-protein interaction network and local regions of genomes has identified numerous cases where subnetworks or local regions have functionally coherent proteins. These results will help interpreting interactions of proteins and gene orders in a genome. Several examples of both analyses are highlighted. Conclusion The analyses demonstrate that applying high confidence predictions from PFP

Hydrogen Production via a High-Efficiency Low-Temperature Reformer

Fuel cells are promoted by the US government as a viable alternative for clean and efficient energy generation. It is anticipated that the fuel cell market will rise if the key technical barriers can be overcome. One of them is certainly fuel processing and purification. Existing fuel reforming processes are energy intensive, extremely complicated and capital intensive; these disadvantages handicap the scale-down of existing reforming process, targeting distributed or on-board/stationary hydrogen production applications. Our project involves the bench-scale demonstration of a high-efficiency low-temperature steam reforming process. Hydrogen production can be operated at 350 to 400ºC with our invention, as opposed to >800ºC of existing reforming. In addition, our proposed process improves the start-up deficiency of conventional reforming due to its low temperature operation. The objective of this project is to demonstrate the invented process concept via a bench scale unit and verify mathematical simulation for future process optimization study. Under this project, we have performed the experimental work to determine the adsorption isotherm, reaction kinetics, and membrane permeances required to perform the process simulation based upon the mathematical model developed by us. A ceramic membrane coated with palladium thin film fabricated by us was employed in this study. The adsorption isotherm for a selected hydrotalcite adsorbent was determined experimentally. Further, the capacity loss under cyclic adsorption/desorption was confirmed to be negligible. Finally a commercial steam reforming catalyst was used to produce the reaction kinetic parameters required for the proposed operating condition. With these input parameters, a mathematical simulation was performed to predict the performance of the invented process. According to our simulation, our invented hybrid process can deliver 35 to 55% methane conversion, in comparison with the 12 and 18-21% conversion of

Byers, E Sandra; Nichols, Shana; Voyer, Susan D

2013-11-01

This study examined the sexual functioning of single adults (61 men, 68 women) with high functioning autism and Asperger syndrome living in the community with and without prior relationship experience. Participants completed an on-line questionnaire assessing autism symptoms, psychological functioning, and various aspects of sexual functioning. In general participants reported positive sexual functioning. Participants without prior relationship experience were significantly younger and more likely to be male and identify as heterosexual. They reported significantly higher sexual anxiety, lower sexual arousability, lower dyadic desire, and fewer positive sexual cognitions. The men reported better sexual function than did the women in a number of areas. These results counter negative societal perceptions about the sexuality of high functioning individuals on the autism spectrum.

Oquendo-Rodriguez, Aida L.

Professions and careers related to science and mathematics lack representation of minorities. Within these underrepresented minority populations there is no other group more affected than Latina women and girls. Women in general, are still underrepresented in many areas of our society. While women's roles are changing in today's society, most changes encourage the participation of more White/Anglo women in traditionally male roles. Latina women are still more disadvantaged than White women. There is no doubt that education is significant in increasing the participation of minorities in the fields of science and mathematics, especially for minority girls (Oakes, 1990; Rodriguez, 1993). This study explored the interests, life experiences, characteristics and motivations of Latina girls of Puerto Rican origin who are successful in science and mathematics high school courses. The study identifies factors that can influence the interest of Latina girls of Puerto Rican origin in science and mathematics career choices. This research is significant and relevant to educators and policy makers, especially to science and mathematics educators. The research is primarily descriptive and exploratory. It explores the social characteristics of Latina girls and professional women who have been successful in science and mathematics high school courses. The research offers the reader a visit to the participants' homes with descriptions and the opportunity to explore the thoughts and life experiences of Latina girls, their mothers and young Latina professionals of Puerto Rican origin. This research reveals the common characteristics of successful students found in the Latina girls of Puerto Rican origin who where interviewed.

Origin of life: hypothesized roles of high-energy electrical discharges, infrared radiation, thermosynthesis and pre-photosynthesis.

Trevors, J T

2012-12-01

The hypothesis is proposed that during the organization of pre-biotic bacterial cell(s), high-energy electrical discharges, infrared radiation (IR), thermosynthesis and possibly pre-photosynthesis were central to the origin of life. High-energy electrical discharges generated some simple organic molecules available for the origin of life. Infrared radiation, both incoming to the Earth and generated on the cooling Earth with day/night and warming/cooling cycles, was a component of heat engine thermosynthesis before enzymes and the genetic code were present. Eventually, a primitive forerunner of photosynthesis and the capability to capture visible light emerged. In addition, the dual particle-wave nature of light is discussed from the perspective that life requires light acting both as a wave and particle.

Nonlocality of the original Einstein-Podolsky-Rosen state

Cohen, O.

1997-11-01

We examine the properties and behavior of the original Einstein-Podolsky-Rosen (EPR) wave function [Phys. Rev. 47, 777 (1935)] and related Gaussian-correlated wave functions. We assess the degree of entanglement of these wave functions and consider an argument of Bell [Ann. (N.Y.) Acad. Sci. 480, 263 (1986)] based on the Wigner phase-space distribution [Phys. Rev. 40, 749 (1932)], which implies that the original EPR correlations can accommodate a local hidden-variable description. We extend Bell's analysis to the related Gaussian wave functions. We then show that it is possible to identify definite nonlocal aspects for the original EPR state and related states. We describe possible experiments that would demonstrate these nonlocal features through violations of Bell inequalities. The implications of our results, and in particular their relevance for the causal interpretation of quantum mechanics, are considered.

Alcohol use among underage youth has a major impact on public health, accidents, fatalities, and other problem behaviors. In Israel, alcohol use, binge drinking, and related problem behaviors are a growing concern. The purpose of this study was to examine underserved and underreported Ethiopian origin youth by comparing their substance use patterns and behavior with other high-risk youth. Data were collected from a purposive sample of boys of Ethiopian, former Soviet Union, and Israeli origin who were receiving treatment for drug use. Youth were asked to complete a simply worded self-report questionnaire developed for monitoring substance use and related problem behaviors. Ethiopian youth reported higher rates of family unemployment and public welfare dependence, last 30-day consumption of beer and hard liquor, serious fighting, and achievement decline when in school compared with the other youths. Findings highlight the need for ethno-cultural specific prevention and intervention efforts and further research of this high-risk, underserved group of immigrant origin youth.

Liu, Guohai; Vimalchand, Pannalal; Peng, WanWang

2015-11-13

This invention relates to gasification of high ash bituminous coals that have high ash fusion temperatures. The ash content can be in 15 to 45 weight percent range and ash fusion temperatures can be in 1150.degree. C. to 1500.degree. C. range as well as in excess of 1500.degree. C. In a preferred embodiment, such coals are dealt with a two stage gasification process--a relatively low temperature primary gasification step in a circulating fluidized bed transport gasifier followed by a high temperature partial oxidation step of residual char carbon and small quantities of tar. The system to process such coals further includes an internally circulating fluidized bed to effectively cool the high temperature syngas with the aid of an inert media and without the syngas contacting the heat transfer surfaces. A cyclone downstream of the syngas cooler, operating at relatively low temperatures, effectively reduces loading to a dust filtration unit. Nearly dust- and tar-free syngas for chemicals production or power generation and with over 90%, and preferably over about 98%, overall carbon conversion can be achieved with the preferred process, apparatus and methods outlined in this invention.

237 Np is one of the longest-lived nuclides among the actinides present in the high level waste solutions of reprocessing origin. Its separation, recovery and transmutation can reduce the problem of long term storage of the vitrified waste to a great extent. With this objective, the present work was initiated to study the extraction of neptunium into TBP under the conditions relevant to high level waste, along with uranium and plutonium by oxidising it to hexavalent state using potassium dichromate and subsequently recovering it by selective stripping. Three types of simulated HLW solutions namely sulphate bearing (SB), with an acidity of ∼ 0.3 M and non-sulphate wastes originating from the reprocessing of fuels from pressurised heavy water reactor (PHWR) and fast breeder reactor (FBR) with acidities of 3.0 M HNO 3 were employed in these studies. The extraction of U(VI), Np(VI) and Pu(VI) was very high for PHWR- and FBR-HLW solutions, whereas for the SB-HLW solution, these values were less but reasonably high. Quantitative recovery of neptunium and plutonium was achieved using a stripping solution containing 0.1 M H 2 O 2 and 0.01 M ascorbic acid at an acidity of 2.0 M. Since, cerium present in the waste solutions is expected to undergo oxidation in presence of K 2 Cr 2 O 7 , its extraction behaviour was also studied under similar conditions. Based on the results, a scheme was formulated for the recovery of neptunium along with plutonium and was successfully applied to actual high level waste solution originating from the reprocessing of research reactor fuels.

Convergent Evolution of Hemoglobin Function in High-Altitude Andean Waterfowl Involves Limited Parallelism at the Molecular Sequence Level.

Directory of Open Access Journals (Sweden)

2015-12-01

Full Text Available A fundamental question in evolutionary genetics concerns the extent to which adaptive phenotypic convergence is attributable to convergent or parallel changes at the molecular sequence level. Here we report a comparative analysis of hemoglobin (Hb function in eight phylogenetically replicated pairs of high- and low-altitude waterfowl taxa to test for convergence in the oxygenation properties of Hb, and to assess the extent to which convergence in biochemical phenotype is attributable to repeated amino acid replacements. Functional experiments on native Hb variants and protein engineering experiments based on site-directed mutagenesis revealed the phenotypic effects of specific amino acid replacements that were responsible for convergent increases in Hb-O2 affinity in multiple high-altitude taxa. In six of the eight taxon pairs, high-altitude taxa evolved derived increases in Hb-O2 affinity that were caused by a combination of unique replacements, parallel replacements (involving identical-by-state variants with independent mutational origins in different lineages, and collateral replacements (involving shared, identical-by-descent variants derived via introgressive hybridization. In genome scans of nucleotide differentiation involving high- and low-altitude populations of three separate species, function-altering amino acid polymorphisms in the globin genes emerged as highly significant outliers, providing independent evidence for adaptive divergence in Hb function. The experimental results demonstrate that convergent changes in protein function can occur through multiple historical paths, and can involve multiple possible mutations. Most cases of convergence in Hb function did not involve parallel substitutions and most parallel substitutions did not affect Hb-O2 affinity, indicating that the repeatability of phenotypic evolution does not require parallelism at the molecular level.

Full Text Available The paper discusses the use of words of foreign origin in Slovenian political discourse. At the outset, this usage is broken down into four groups: the first contains specific phrases and terminology inherent to the political domain; the second contains words of foreign origin generally present in the Slovene language (because of their high frequency of nonexclusivistic use, these words are not of interest to the scope of this investigation; the third contains various words of foreign origin used as affectional packaging for messages with the aim of stimulating the desired interpretation (framing reality; the fourth group, which is the most interesting for our research, is made up of words of foreign origin which could have a marker: + marked, + not necessary, + unwanted, but only if we accept the logic of purism. All the words in this group could be replaced - without any loss of meaning - with their Slovene equivalents. The speakerʼs motivation for using the foreign word is crucial to our discussion. In the framework of Pierre Bourdieuʼs poststructural theory as well as Austinʼs and Searleʼs speech act theory, statistical data is analysed to observe how usage frequency varies in correlation with selected factors which manifest the speakerʼs habitus. We argue that words of foreign origin represent symbolic cultural capital, a kind of added value which functions as credit and as such is an important form of the accumulation of capital.

We present a simple model that explains the origin of warm, diffuse gas seen primarily as highly ionized absorption-line systems in the spectra of background sources. We predict the observed column densities of several highly ionized transitions such as O vi, O vii, Ne viii, N v, and Mg x, and we present a unified comparison of the model predictions with absorption lines seen in the Milky Way disk, Milky Way halo, starburst galaxies, the circumgalactic medium, and the intergalactic medium at low and high redshifts. We show that diffuse gas seen in such diverse environments can be simultaneously explained by a simple model of radiatively cooling gas. We show that most such absorption-line systems are consistent with being collisionally ionized, and we estimate the maximum-likelihood temperature of the gas in each observation. This model satisfactorily explains why O vi is regularly observed around star-forming low- z L* galaxies, and why N v is rarely seen around the same galaxies. We further present some consequences of this model in quantifying the dynamics of the cooling gas around galaxies and predict the shock velocities associated with such flows. A unique strength of this model is that while it has only one free (but physically well-constrained) parameter, it nevertheless successfully reproduces the available data on O vi absorbers in the interstellar, circumgalactic, intragroup, and intergalactic media, as well as the available data on other absorption lines from highly ionized species.

The paper described multi-stimuli-responsive materials out of the technology developments for creating original high-functional materials under the system of R and D of industrial scientific technologies. These are materials which repeatedly reproduce functions such as separation, penetration and movement in response to stimuli by imitating living organisms. In relation to polymer multi-stimuli-responsive materials, various copolymers were synthesized using N-acetyl (meta) acrylamide, of which the synthesis method was established in the previous fiscal year, as a main component, and thermal responsive polymer with upper critical solution temperature which becomes a base of separation functional materials was searched for. By immobilizing it with molecular recognition ligand, measured was thermal dependence of affinity of the immobilized matter to albumin. Also studied were molecular recognition cell adhesion/separation functional materials. Concerning composite multi-stimuli-responsive materials, with the use of silica microcapsule surface-immobilized with silane coupling agent, studied were the optimum conditions for immobilizing thermo-responsive polymer to the surface of the capsule. Using motion functional materials by ion exchange resin, obtained was motion functionality which is satisfactory at the state of practical use. 94 refs., 82 figs., 16 tabs.

Invention and validation of an automated camera system that uses optical character recognition to identify patient name mislabeled samples.

Hawker, Charles D; McCarthy, William; Cleveland, David; Messinger, Bonnie L

Mislabeled samples are a serious problem in most clinical laboratories. Published error rates range from 0.39/1000 to as high as 1.12%. Standardization of bar codes and label formats has not yet achieved the needed improvement. The mislabel rate in our laboratory, although low compared with published rates, prompted us to seek a solution to achieve zero errors. To reduce or eliminate our mislabeled samples, we invented an automated device using 4 cameras to photograph the outside of a sample tube. The system uses optical character recognition (OCR) to look for discrepancies between the patient name in our laboratory information system (LIS) vs the patient name on the customer label. All discrepancies detected by the system's software then require human inspection. The system was installed on our automated track and validated with production samples. We obtained 1 009 830 images during the validation period, and every image was reviewed. OCR passed approximately 75% of the samples, and no mislabeled samples were passed. The 25% failed by the system included 121 samples actually mislabeled by patient name and 148 samples with spelling discrepancies between the patient name on the customer label and the patient name in our LIS. Only 71 of the 121 mislabeled samples detected by OCR were found through our normal quality assurance process. We have invented an automated camera system that uses OCR technology to identify potential mislabeled samples. We have validated this system using samples transported on our automated track. Full implementation of this technology offers the possibility of zero mislabeled samples in the preanalytic stage.

Traditionally, the mechanism of wheelchair with lifting and standing functions has 2 degrees of freedom, and used 2 power sources to perform these 2 motion function. The purpose of this paper is to invent new wheelchair with 1 degree of freedom to perform these 2 motion functions. Hence, we can use only 1 power source to drive the mechanism to achieve lifting and standing motion functions. The new design has the advantages of simple operation, more stability, and more safety. For traditional standing wheelchair, its’ centre of gravity moves forward when standing up and it needs 2 auxiliary wheels to prevent dumping. In this paper, by using the checklist method of Osborn, the wheelchair with 1 DOF is invented to perform lifting and standing functions. The centre of gravity of this new wheelchair after standing up still located between the front and rear wheels, no auxiliary wheels needed. Finally, the prototype is manufactured to verify the theoretical results.

Metal surfaces operated under high electric fields produce sparks even if they are held in ultra high vacuum. In spite of extensive research on the topic of vacuum arcs, the mystery of vacuum arc origin still remains unresolved. The indications that the sparking rates depend on the material motivate the research on surface response to extremely high external electric fields. In this work by means of density-functional theory calculations we analyze the redistribution of electron density on (100) Cu surfaces due to self-adatoms and in presence of high electric fields from −1 V/nm up to −2 V/nm (−1 to −2 GV/m, respectively). We also calculate the partial charge induced by the external field on a single adatom and a cluster of two adatoms in order to obtain reliable information on charge redistribution on surface atoms, which can serve as a benchmarking quantity for the assessment of the electric field effects on metal surfaces by means of molecular dynamics simulations. Furthermore, we investigate the modifications of work function around rough surface features, such as step edges and self-adatoms.

The origin, function and disappearance of the “Twelve”: Continuity from Jesus to the post-Easter community?

Directory of Open Access Journals (Sweden)

Dietrich-Alex Koch

2005-10-01

Full Text Available The group of the Twelve is mentioned 28 times in the Synoptic Gospels. However, the Evangelists were not familiar with the historical role of the Twelve. Even the pre-Easter origin of Matthew 19:28/Luke 22:30 is debatable. On the other hand 1 Corinth 15:3b-5 provides a solid basis for the assumption of a pre-Easter origin of the Twelve. They functioned as a group representing the twelve tribes of Israel as the eschatological people of God. Reaffirmed in this role by the risen Lord they had for a short time a leading role in the early Christian community in Jerusalem. But their importance soon declined because after a short time the twelve former disciples from Galilee could no longer be representative of a rapidly expanding community. In the last decades of the first century the Twelve got a new importance on the literary level of the Gospels.

Full Text Available Cataract with high myopia is research priority associated with the large amount of high myopia patients. The unaided visual acuity and the best-corrected visual acuity are partial for the visual acuity of the patients with cataract. The mechanism and clinical significance of modern visual function measurements associated with cataract and high myopia, including accommodation and convergence, stereoscopic vision, contrast sensitivity, have been introduced. These measurements could be of great value in early diagnosis of cataract, assessment of surgical indication, customized intraocular lens(IOLselection and evaluation of visual performance after IOL implantation. They could also be helpful to the analysis of postoperative impaired visual function and its management. Having an adequate understanding of the contents and significance of visual function was helpful to the improvement of cataract surgery techniques and postoperative visual acuity.

When tropical systems lose species, they are often assumed to be buffered against declines in functional diversity by the ability of the species-rich biota to display high functional redundancy: i.e., a high number of species performing similar functions. We tested this hypothesis using a ninefold richness gradient in global fish faunas on tropical reefs encompassing 6,316 species distributed among 646 functional entities (FEs): i.e., unique combinations of functional traits. We found that the highest functional redundancy is located in the Central Indo-Pacific with a mean of 7.9 species per FE. However, this overall level of redundancy is disproportionately packed into few FEs, a pattern termed functional over-redundancy (FOR). For instance, the most speciose FE in the Central Indo-Pacific contains 222 species (out of 3,689) whereas 38% of FEs (180 out of 468) have no functional insurance with only one species. Surprisingly, the level of FOR is consistent across the six fish faunas, meaning that, whatever the richness, over a third of the species may still be in overrepresented FEs whereas more than one third of the FEs are left without insurance, these levels all being significantly higher than expected by chance. Thus, our study shows that, even in high-diversity systems, such as tropical reefs, functional diversity remains highly vulnerable to species loss. Although further investigations are needed to specifically address the influence of redundant vs. vulnerable FEs on ecosystem functioning, our results suggest that the promised benefits from tropical biodiversity may not be as strong as previously thought.

High pressure/temperature was applied on samples of pristine multi-walled carbon nanotubes (MWCNT), functionalized nanotubes (f-MWCNT), and nanotubes doped with nitrogen (CN{sub x}MWNT). Cylindrical compact pellets of f-MWCNT with diameters of about 6 mm were obtained under pressure of 4.0 GPa at room temperature and at 400 °C, using graphite as pressure transmitting medium. The best pellet samples were produced using nitric and sulfuric acids for the functionalization of MWCNT. The effect of high pressure/temperature on CNT was investigated by several spectroscopy and characterization techniques, such as Raman spectroscopy, X-ray powder diffraction, X-ray photoelectron spectroscopy, N{sub 2} adsorption/desorption isotherms, and transmission electron microscopy. It was found that MWCNT maintain their main features in the compacted pellets, such as integrity, original morphology, and structure, demonstrating that high-pressure/temperature compaction can indeed be used to fabricate novel CNT self-supported materials. Additionally, the specific surface area and porosity are unchanged, which is important when using bulk CNT in adsorption processes. Raman analysis of the G’-band showed a shift to lower wavenumbers when f-MWCNT were processed under high pressure, suggesting that CNT are under tensile stress.

Sericulture is one of the great inventions of the ancient Chinese. Besides the mulberry silkworm (Bombyx mori), Chinese farmers developed rearing of the Chinese oak silkworm (Antheraea pernyi) about 400 years ago. In this paper, the historic records of the origins and dispersal of the domesticated Chinese oak silkworm in China are summarized. The first document with clearly recorded oak silkworm artificial rearing appeared in 1651, although Chinese oak silkworm was documented in about 270 AD. All of the evidence in the available historic records suggests that the domesticated Chinese oak silkworm originated in central and southern areas of Shandong Province in China around the 16th century, and then was introduced directly and indirectly by human commerce into the present habitations in China after the late 17th century. The results strongly support the hypothesis that only one geographically distinct event occurred in domestication of the modern Chinese oak silkworm.

Multiple determinants controlling activation of yeast replication origins late in S phase.

Friedman, K L; Diller, J D; Ferguson, B M; Nyland, S V; Brewer, B J; Fangman, W L

1996-07-01

Analysis of a 131-kb segment of the left arm of yeast chromosome XIV beginning 157 kb from the telomere reveals four highly active origins of replication that initiate replication late in S phase. Previous work has shown that telomeres act as determinants for late origin activation. However, at least two of the chromosome XIV origins maintain their late activation time when located on large circular plasmids, indicating that late replication is independent of telomeres. Analysis of the replication time of plasmid derivatives containing varying amounts of chromosome XIV DNA show that a minimum of three chromosomal elements, distinct from each tested origin, contribute to late activation time. These late determinants are functionally equivalent, because duplication of one set of contributing sequences can compensate for the removal of another set. Furthermore, insertion of an origin that is normally early activated into this domain results in a shift to late activation, suggesting that the chromosome XIV origins are not unique in their ability to respond to the late determinants.

Constructive Approaches for Understanding the Origin of Self-Replication and Evolution

Directory of Open Access Journals (Sweden)

Norikazu Ichihashi

Full Text Available The mystery of the origin of life can be divided into two parts. The first part is the origin of biomolecules: under what physicochemical conditions did biomolecules such as amino acids, nucleotides, and their polymers arise? The second part of the mystery is the origin of life-specific functions such as the replication of genetic information, the reproduction of cellular structures, metabolism, and evolution. These functions require the coordination of many different kinds of biological molecules. A direct strategy to approach the second part of the mystery is the constructive approach, in which life-specific functions are recreated in a test tube from specific biological molecules. Using this approach, we are able to employ design principles to reproduce life-specific functions, and the knowledge gained through the reproduction process provides clues as to their origins. In this mini-review, we introduce recent insights gained using this approach, and propose important future directions for advancing our understanding of the origins of life.

Among the production channels of the Higgs boson one contribution could become significant at high transverse momentum which is the radiation of a Higgs boson from another particle. This note focuses on the calculation of splitting functions and cross sections of such processes. The calculation is first carried out on the example $e\\rightarrow e\\gamma$ to illustrate the way splitting functions are calculated. Then the splitting function of $e\\rightarrow eh$ is calculated in similar fashion. This procedure can easily be generalized to processes such as $q\\rightarrow qh$ or $g\\rightarrow gh$.

The diffusion of patented oil and gas technology with environmental uses: A forward patent citation analysis

Duch-Brown, Néstor; Costa-Campi, María Teresa

2015-01-01

Relevant advances in the mitigation of environmental impact could be obtained by the appropriate diffusion of existing environmental technologies. In this paper, we look at the diffusion of knowledge related to environmental technologies developed within the oil and gas industry. To assess knowledge spillovers from oil and gas inventions as a measure of technology diffusion, we rely on forward patent citations methodology. Results show that there is a strong likelihood that the citing patent will be eventually linked to environmental technologies if the original oil and gas invention has already environmental uses. Moreover, both intra and intersectoral spillovers produce a “turnabout” effect, meaning that citing patents show the opposite quality level of the cited patent. Our results support the idea that more sector-specific environmental policies, with an emphasis on diffusion, would significantly improve the use of environmental technologies developed within the oil and gas industry. -- Highlights: •Knowledge spillovers from oil and gas inventions are of an intrasectoral nature. •Environmental uses in original patents diffuse to patents with environmental uses. •The “turnabout” effect converts low quality patents into high quality citing patents. •Diffusion of oil and gas inventions need more ad hoc instruments

Contextualising primate origins--an ecomorphological framework.

Science.gov (United States)

Soligo, Christophe; Smaers, Jeroen B

2016-04-01

Ecomorphology - the characterisation of the adaptive relationship between an organism's morphology and its ecological role - has long been central to theories of the origin and early evolution of the primate order. This is exemplified by two of the most influential theories of primate origins: Matt Cartmill's Visual Predation Hypothesis, and Bob Sussman's Angiosperm Co-Evolution Hypothesis. However, the study of primate origins is constrained by the absence of data directly documenting the events under investigation, and has to rely instead on a fragmentary fossil record and the methodological assumptions inherent in phylogenetic comparative analyses of extant species. These constraints introduce particular challenges for inferring the ecomorphology of primate origins, as morphology and environmental context must first be inferred before the relationship between the two can be considered. Fossils can be integrated in comparative analyses and observations of extant model species and laboratory experiments of form-function relationships are critical for the functional interpretation of the morphology of extinct species. Recent developments have led to important advancements, including phylogenetic comparative methods based on more realistic models of evolution, and improved methods for the inference of clade divergence times, as well as an improved fossil record. This contribution will review current perspectives on the origin and early evolution of primates, paying particular attention to their phylogenetic (including cladistic relationships and character evolution) and environmental (including chronology, geography, and physical environments) contextualisation, before attempting an up-to-date ecomorphological synthesis of primate origins. © 2016 Anatomical Society.

The Origin and Evolution of Interstellar Dust in the Local and High-redshift Universe

Science.gov (United States)

Dwek, Eliahu

2012-01-01

In this talk I will begin by reviewing our current state of knowledge regarding the origin and evolution of dust in the local solar neighborhood. using chemical evolution models, I will discuss their many different input parameters and their uncertainties. An important consequence of these models is the delayed injection of dust from AGB stars, compared to supernova-condensed dust, into the interstellar medium. I will show that these stellar evolutionary effects on dust composition are manifested in the infrared spectra of local galaxies. The delayed production of dust in AGB stars has also important consequences for the origin of the large amount of dust detected in high-redshift galaxies, when the universe was less that approx. 1 Gyr old. Supernovae may have been the only viable dust sources in those galaxies. Recent observations of sN1987a show a significant mass of dust in the ejecta of this SN. Is that production rate high enough to account for the observed dust mass in these galaxies? If not, what are the alternative viable sources of dust, and how do they depend on the nature of the galaxy (starburst or AGN) and its star formation history .

Around the world, the human-induced collapses of populations and species have triggered a sixth mass extinction crisis, with rare species often being the first to disappear. Although the role of species diversity in the maintenance of ecosystem processes has been widely investigated, the role of rare species remains controversial. A critical issue is whether common species insure against the loss of functions supported by rare species. This issue is even more critical in species-rich ecosystems where high functional redundancy among species is likely and where it is thus often assumed that ecosystem functioning is buffered against species loss. Here, using extensive datasets of species occurrences and functional traits from three highly diverse ecosystems (846 coral reef fishes, 2,979 alpine plants, and 662 tropical trees), we demonstrate that the most distinct combinations of traits are supported predominantly by rare species both in terms of local abundance and regional occupancy. Moreover, species that have low functional redundancy and are likely to support the most vulnerable functions, with no other species carrying similar combinations of traits, are rarer than expected by chance in all three ecosystems. For instance, 63% and 98% of fish species that are likely to support highly vulnerable functions in coral reef ecosystems are locally and regionally rare, respectively. For alpine plants, 32% and 89% of such species are locally and regionally rare, respectively. Remarkably, 47% of fish species and 55% of tropical tree species that are likely to support highly vulnerable functions have only one individual per sample on average. Our results emphasize the importance of rare species conservation, even in highly diverse ecosystems, which are thought to exhibit high functional redundancy. Rare species offer more than aesthetic, cultural, or taxonomic diversity value; they disproportionately increase the potential breadth of functions provided by ecosystems across

Autism spectrum disorder (ASD) is mainly characterized by functional and communication impairments as well as restrictive and repetitive behavior. The leading hypothesis for the neural basis of autism postulates globally abnormal brain connectivity, which can be assessed using functional magnetic resonance imaging (fMRI). Even in the absence of a task, the brain exhibits a high degree of functional connectivity, known as intrinsic, or resting-state, connectivity. Global default connectivity in individuals with autism versus controls is not well characterized, especially for a high-functioning young population. The aim of this study is to test whether high-functioning adolescents with ASD (HFA) have an abnormal resting-state functional connectivity. We performed spatial and temporal analyses on resting-state networks (RSNs) in 13 HFA adolescents and 13 IQ- and age-matched controls. For the spatial analysis, we used probabilistic independent component analysis (ICA) and a permutation statistical method to reveal the RSN differences between the groups. For the temporal analysis, we applied Granger causality to find differences in temporal neurodynamics. Controls and HFA display very similar patterns and strengths of resting-state connectivity. We do not find any significant differences between HFA adolescents and controls in the spatial resting-state connectivity. However, in the temporal dynamics of this connectivity, we did find differences in the causal effect properties of RSNs originating in temporal and prefrontal cortices. The results show a difference between HFA and controls in the temporal neurodynamics from the ventral attention network to the salience-executive network: a pathway involving cognitive, executive, and emotion-related cortices. We hypothesized that this weaker dynamic pathway is due to a subtle trigger challenging the cognitive state prior to the resting state.

Structural changes in Mcm5 protein bypass Cdc7-Dbf4 function and reduce replication origin efficiency in Saccharomyces cerevisiae.

Eukaryotic chromosomal replication is a complicated process with many origins firing at different efficiencies and times during S phase. Prereplication complexes are assembled on all origins in G(1) phase, and yet only a subset of complexes is activated during S phase by DDK (for Dbf4-dependent kinase) (Cdc7-Dbf4). The yeast mcm5-bob1 (P83L) mutation bypasses DDK but results in reduced intrinsic firing efficiency at 11 endogenous origins and at origins located on minichromosomes. Origin efficiency may result from Mcm5 protein assuming an altered conformation, as predicted from the atomic structure of an archaeal MCM (for minichromosome maintenance) homologue. Similarly, an intragenic mutation in a residue predicted to interact with P83L suppresses the mcm5-bob1 bypass phenotype. We propose DDK phosphorylation of the MCM complex normally results in a single, highly active conformation of Mcm5, whereas the mcm5-bob1 mutation produces a number of conformations, only one of which is permissive for origin activation. Random adoption of these alternate states by the mcm5-bob1 protein can explain both how origin firing occurs independently of DDK and why origin efficiency is reduced. Because similar mutations in mcm2 and mcm4 cannot bypass DDK, Mcm5 protein may be a unique Mcm protein that is the final target of DDK regulation.

Purpose: One of the technical advantages of functional magnetic resonance imaging (fMRI) is its precise localization of changes from neuronal activities. While current practice of fMRI acquisition at voxel size around 3 × 3 × 3 mm 3 achieves satisfactory results in studies of basic brain functions, higher spatial resolution is required in order to resolve finer cortical structures. This study investigated spatial resolution effects on brain fMRI experiments using balanced steady-state free precession (bSSFP) imaging with 0.37 mm 3 voxel volume at 3.0 T. Methods: In fMRI experiments, full and unilateral visual field 5 Hz flashing checkerboard stimulations were given to healthy subjects. The bSSFP imaging experiments were performed at three different frequency offsets to widen the coverage, with functional activations in the primary visual cortex analyzed using the general linear model. Variations of the spatial resolution were achieved by removing outerk-space data components. Results: Results show that a reduction in voxel volume from 3.44 × 3.44 × 2 mm 3 to 0.43 × 0.43 × 2 mm 3 has resulted in an increase of the functional activation signals from (7.7 ± 1.7)% to (20.9 ± 2.0)% at 3.0 T, despite of the threefold SNR decreases in the original images, leading to nearly invariant functional contrast-to-noise ratios (fCNR) even at high spatial resolution. Activation signals aligning nicely with gray matter sulci at high spatial resolution would, on the other hand, have possibly been mistaken as noise at low spatial resolution. Conclusions: It is concluded that the bSSFP sequence is a plausible technique for fMRI investigations at submillimeter voxel widths without compromising fCNR. The reduction of partial volume averaging with nonactivated brain tissues to retain fCNR is uniquely suitable for high spatial resolution applications such as the resolving of columnar organization in the brain

Words of foreign origin in political discourse

Full Text Available The paper discusses the use of words of foreign origin in Slovenian political discourse. At the outset, this usage is broken down into four groups: the first contains specific phrases and terminology inherent to the political domain; the second contains words of foreign origin generally present in the Slovene language (because of their high frequency of nonexclusivistic use, these words are not of interest to the scope of this investigation; the third contains various words of foreign origin used as affectional packaging for messages with the aim of stimulating the desired interpretation (framing reality; the fourth group, which is the most interesting for our research, is made up of words of foreign origin which could have a marker: + marked, + not necessary, + unwanted, but only if we accept the logic of purism. All the words in this group could be replaced - without any loss of meaning - with their Slovene equivalents. The speakerʼs motivation for using the foreign word is crucial to our discussion. In the framework of Pierre Bourdieuʼs poststructural theory as well as Austinʼs and Searleʼs speech act theory, statistical data is analysed to observe how usage frequency varies in correlation with selected factors which manifest the speakerʼs habitus. We argue that words of foreign origin represent symbolic cultural capital, a kind of added value which functions as credit and as such is an important form of the accumulation of capital.       

Microscopic Origins of the Anomalous Melting Behavior of Sodium under High Pressure

2012-03-01

X-ray diffraction experiments have shown that sodium exhibits a dramatic pressure-induced drop in melting temperature, which extends from 1000 K at ˜30GPa to as low as room temperature at ˜120GPa. Despite significant theoretical effort to understand the anomalous melting, its origins are still debated. In this work, we reconstruct the sodium phase diagram by using an ab initio quality neural-network potential. Furthermore, we demonstrate that the reentrant behavior results from the screening of interionic interactions by conduction electrons, which at high pressure induces a softening in the short-range repulsion.

The local origin of dipolar distortions in ABO{sub 3} perovskite crystals is reexamined by means of a novel approach, the Green's function method augmented by DFT computations. The ferroelectric distortions are shown to be induced by the pseudo Jahn–Teller effect (PJTE). The latter involves vibronic hybridization (admixture) of the ground state to same-spin opposite-parity excited electronic bands. Similar to numerous molecular calculations, the PJT approach provides a deeper insight into the nature of chemical bonding in the octahedral cluster [BO{sub 6}] and, in particular, reveals the local origin of its polar instability. This allows predicting directly which transition ions can create ferroelectricity. In particular, the necessary conditions are established when an ABO{sub 3} perovskite crystal with an electronic d{sup n} configuration of the complex ion [BO{sub 6}] can possess both proper ferroelectric and magnetic properties. Distinguished from the variety of cluster approaches to local properties, the Green's function method includes the influence of the local vibronic-coupling perturbation on the whole crystal via the inter-cell interaction responsible for creation of electronic and vibrational bands. Calculated Green's functions combined with the corresponding numeric estimates for the nine electronic bands, their density of states, and the local adiabatic potential energy surface (APES) confirm the eight-minimum form of this surface and feasibility of the PJT origin of the polar instability in BaTiO{sub 3}. We show also that multicenter long-range dipole–dipole interactions critically depend on the PJTE largely determining the magnitude of the local dipoles. DFT calculations for the bulk crystal and its clusters confirm that the dipolar distortions are of local origin, but become possible only when their influence on (relaxation of) the whole lattice is taken into account. The results are shown to be in full qualitative and

Revisit the Candidacy of Brain Cell Types as the Cell(s of Origin for Human High-Grade Glioma

Full Text Available High-grade glioma, particularly, glioblastoma, is the most aggressive cancer of the central nervous system (CNS in adults. Due to its heterogeneous nature, glioblastoma almost inevitably relapses after surgical resection and radio-/chemotherapy, and is thus highly lethal and associated with a dismal prognosis. Identifying the cell of origin has been considered an important aspect in understanding tumor heterogeneity, thereby holding great promise in designing novel therapeutic strategies for glioblastoma. Taking advantage of genetic lineage-tracing techniques, performed mainly on genetically engineered mouse models (GEMMs, multiple cell types in the CNS have been suggested as potential cells of origin for glioblastoma, among which adult neural stem cells (NSCs and oligodendrocyte precursor cells (OPCs are the major candidates. However, it remains highly debated whether these cell types are equally capable of transforming in patients, given that in the human brain, some cell types divide so slowly, therefore may never have a chance to transform. With the recent advances in studying adult NSCs and OPCs, particularly from the perspective of comparative biology, we now realize that notable differences exist among mammalian species. These differences have critical impacts on shaping our understanding of the cell of origin of glioma in humans. In this perspective, we update the current progress in this field and clarify some misconceptions with inputs from important findings about the biology of adult NSCs and OPCs. We propose to re-evaluate the cellular origin candidacy of these cells, with an emphasis on comparative studies between animal models and humans.

A damper was invented to remove undesirable stress pulses from an acoustic waveguide. Designed to be tunable, the damper was constructed to withstand a corrosive or otherwise hostile environment. It serves to simplify the design and enhance the performance of a water-level measurement system, of which the damper and acoustic waveguide are integral parts. An experimental damper was constructed and applied to an existing level probe and measurement system. The resulting damper, properly tuned, causes acoustic stress pulses that pass into it along the waveguide to be attenuated

In July 2008, the Global Threat Reduction Initiative and the IRT 2000 research reactor in Sofia, Bulgaria, operated by the Institute for Nuclear Research and Nuclear Energy (INRNE), safely shipped 6.4 kilograms of Russian origin highly enriched uranium (HEU) spent nuclear fuel (SNF) to the Russian Federation. The shipment, which resulted in the removal of all HEU from Bulgaria, was conducted by truck, barge, and rail modes of transport across two transit countries before reaching the final destination at the Production Association Mayak facility in Chelyabinsk, Russia. This paper describes the work, equipment, organizations, and approvals that were required to complete the spent fuel shipment and provides lessons learned that might assist other research reactor operators with their own spent nuclear fuel shipments.
