    The Bologna process is to improve the quality of education, mobility, diversity and the competitiveness and involves three fundamental changes: transform of the structure of titles, changing in methods of teaching and implementation of the systems of quality assurance. Once that the new degrees have been implemented with this structure, and began at E.T.S. of Agriculture Engineering (ETSIA) at Madrid from 2010-2011 course, the main aim of this work is to deeply study the changes in teaching methodology as well as progressively implementation of the educational planning of the three new degrees: Engineering and Agronomic Graduate, Food Industry Engineering Graduate and Agro-environmental Graduate. Each one of them presents 240 ECTS with a common first course and will have access to an official Master in Agronomic Engineering. As part as an educational innovation project awarded by the Technical University of Madrid (UPM) to improve educational quality, the second course has been designed with the main objective to continue the educative model implemented last course. This model identifies several teaching activities and represents a proper teaching style at ETSIA-UPM. At the same time, a monitoring and development coordination plans have been established. On the other hand, a procedure to extinguish the earlier plans of Agriculture Engineering was also defined. Other activities related to this Project were the information improvement of the grades, in particular at High Schools centers, improving the processes of reception, counseling and tutoring and mentoring. Likewise, cooperative working workshops and programs to support the teaching of English language were implemented. Satisfaction surveys and opinion polls were done to professors and students involved in first course in order to test several aspects of this project. The students surveys were analyzed taking in account the academic results and their participation in mentoring activities giving a highly

    Full Text Available In recent decades some countries of the Middle East have offered facilities to attract international students to pursue their higher education within their higher education institutions. The purpose of this study is to understand the difficulties faced by these students while conducting their studies abroad, and in doing so, to broaden the awareness of the challenges they face to complete their research. The participants of this qualitative study are international PhD students studying at a Middle Eastern public university. The university has reported increasing enrollment of international students, particularly from Africa in the last few years. Data were collected using a set of semi-structured interviews that drew out information on critical incidents that characterized the kind of difficulties students had faced in their studies. The data collected was further analyzed using a qualitative software package, NVivo (QSR International, 11. Six main themes came out from the content analysis of the interviews, which are the role of the adviser, student features, funding issues, family engagement, research and psychological obstacles which provide a holistic picture of student perspectives on the factors that influence degree progress. While these students might have faced difficulties mentioned in existing literature, this study argues that the participants have indicated experiencing psychological obstacles that were not described in earlier studies, such as the state of mind they were in as a result of being worried for family members due to war or violence in their home countries, and drop in currency exchange rates and difficulties in acquiring money due to international sanctions imposed against their countries. This study provides important thoughts on the factors that impact the degree progress of international PhD students from Africa, while at the same time revealing a serious gap in the advisers’ role which can contribute to the

  8. Degree program changes and curricular flexibility: Addressing long held beliefs about student progression

    Science.gov (United States)

    Ricco, George Dante

    In higher education and in engineering education in particular, changing majors is generally considered a negative event - or at least an event with negative consequences. An emergent field of study within engineering education revolves around understanding the factors and processes driving student changes of major. Of key importance to further the field of change of major research is a grasp of large scale phenomena occurring throughout multiple systems, knowledge of previous attempts at describing such issues, and the adoption of metrics to probe them effectively. The problem posed is exacerbated by the drive in higher education institutions and among state legislatures to understand and reduce time-to-degree and student attrition. With these factors in mind, insights into large-scale processes that affect student progression are essential to evaluating the success or failure of programs. The goals of this work include describing the current educational research on switchers, identifying core concepts and stumbling blocks in my treatment of switchers, and using the Multiple Institutional Database for Investigating Engineering Longitudinal Development (MIDFIELD) to explore how those who change majors perform as a function of large-scale academic pathways within and without the engineering context. To accomplish these goals, it was first necessary to delve into a recent history of the treatment of switchers within the literature and categorize their approach. While three categories of papers exist in the literature concerning change of major, all three may or may not be applicable to a given database of students or even a single institution. Furthermore, while the term has been coined in the literature, no portable metric for discussing large-scale navigational flexibility exists in engineering education. What such a metric would look like will be discussed as well as the delimitations involved. The results and subsequent discussion will include a description of

    Objectives. To characterize pharmacy/MBA professionals during their entry-level and current positions and to describe their attitudes and perceptions toward their combined degree. Methods. A cross-sectional survey of University at Buffalo (UB) alumni who obtained both pharmacy and MBA degrees was used. An electronic survey was developed through collaboration with the UB School of Management and administered in winter 2015. Results. A total of 68/115 (59% response rate) pharmacy/MBA professionals responded to the survey. Post-graduate training was completed by 24% of respondents, and most commonly it was a residency program. After adjusting for inflation to 2014 dollars, the median entry-level salary for pharmacy/MBA professionals was $140,123 (mean = $144,327) and this increased to $179,947 (mean = $205,623) for those in their current position. Practice settings for entry-level professionals included pharmaceutical industry (25%) and chain pharmacies (18%). Most respondents believed that a combined degree helped in career advancement (85%) and made them more competitive in the job market (90%). Conclusion. Pharmacy/MBA professionals are well-compensated, work in a wide-range of professional settings, and have a high-level of satisfaction with their combined degree.

    Patients with mild cognitive impairment (MCI) are at high risk for developing Alzheimer's disease (AD), while some of them may remain stable over decades. The underlying mechanism is still not fully understood. In this study, we aimed to explore the connectivity differences between progressive MCI (PMCI) and stable MCI (SMCI) individuals on a whole-brain scale and on a voxel-wise basis, and we also aimed to reveal the differential dynamic alteration patterns between these two disease subtypes. The resting-state functional magnetic resonance images of PMCI and SMCI patients at baseline and year-one were obtained from the Alzheimer's Disease Neuroimaging Initiative dataset, and the progression was determined based on a 3-year follow-up. A whole-brain voxel-wise degree map that was calculated based on graph-theory was constructed for each subject, and then the cross-sectional and longitudinal analyses on the degree maps were performed between PMCI and SMCI patients. In longitudinal analyses, compared with SMCI group, PMCI group showed decreased long-range degree in the left middle occipital/supramarginal gyrus, while the short-range degree was increased in the left supplementary motor area and middle frontal gyrus and decreased in the right middle temporal pole. A significant longitudinal alteration of decreased short-range degree in the right middle occipital was found in PMCI group. Taken together with previous evidence, our current findings may suggest that PMCI, compared with SMCI, might be a "severe" presentation of disease along the AD continuum, and the rapidly reduced degree in the right middle occipital gyrus may have indicative value for the disease progression. Moreover, the cross-sectional comparison results and corresponding receiver-operator characteristic-curves analyses may indicate that the baseline degree difference is not a good predictor of disease progression in MCI patients. Overall, these findings may provide objective evidence and an indicator

    Full Text Available Abstract Background The factors influencing curve behavior following bracing are incompletely understood and there is no agreement if scoliotic curves stop progressing with skeletal maturity. The aim of this study was to evaluate the loss of the scoliotic curve correction in patients treated with bracing during adolescence and to compare patient outcomes of under and over 30 Cobb degrees, 10 years after brace removal. Methods We reviewed 93 (87 female of 200 and nine patients with adolescent idiopathic scoliosis (AIS who were treated with the Lyon or PASB brace at a mean of 15 years (range 10–35. All patients answered a simple questionnaire (including work status, pregnancy, and pain and underwent clinical and radiological examination. The population was divided into two groups based on Cobb degrees ( 30°. Statistical analysis was performed to test the efficacy of our hypothesis. Results The patients underwent a long-term follow-up at a mean age of 184.1 months (±72.60 after brace removal. The pre-brace scoliotic mean curve was 32.28° (± 9.4°; after treatment, the mean was 19.35° and increased to a minimum of 22.12° in the 10 years following brace removal. However, there was no significant difference in the mean Cobb angle between the end of weaning and long term follow-up period (p = 0.105. The curve angle of patients who were treated with a brace from the beginning was reduced by 13° during the treatment, but the curve size lost 3° at the follow-up period. The groups over 30° showed a pre-brace scoliotic mean curve of 41.15°; at the end of weaning, the mean curve angle was 25.85° and increased to a mean of 29.73° at follow-up; instead, the groups measuring ≤ 30° showed a pre-brace scoliotic mean curve of 25.58°; at the end of weaning, it was reduced to a mean of 14.24° and it increased to 16.38° at follow-up. There was no significant difference in the mean progression of curve magnitude between the ≤ 30° and

    Vertex degree of many network models and real-life networks is limited to non-negative integer. By means of measure and integral, the relation of the degree distribution and the cumulative degree distribution in discrete case is analyzed. The degree distribution, obtained by the differential of its cumulative, is only suitable for continuous case or discrete case with constant degree change. When degree change is not a constant but proportional to degree itself, power-law degree distribution and its cumulative have the same exponent and the mean value is finite for power-law exponent greater than 1. -- Highlights: → Degree change is the crux for using the cumulative degree distribution method. → It suits for discrete case with constant degree change. → If degree change is proportional to degree, power-law degree distribution and its cumulative have the same exponent. → In addition, the mean value is finite for power-law exponent greater than 1.

    Full Text Available People have tended to load their different conceptions of democracy with their own political ideals; in this paper it is argued that normative and definitional questions should rather be separated, so that political philosophers and political scientists may adopt the same concept of democracy, even if they disagree normatively or politically. Moreover, it is argued that we should replace an absolute notion of democracy by a relativized notion, which allows for different degrees of democraticity. This facilitates the separation of normative and conceptual issues and it is convenient in contexts in which “democratic deficits” are discussed – as e.g. when democracy is to be implemented on a supranational level. Moreover, it has the consequence that democratic deficits are not necessarily bad. DOWNLOAD THIS PAPER FROM SSRN: http://ssrn.com/abstract=1837342

The aim of nuclear physics today is to understand the interaction dynamics in nuclei of particles whose existence is known by high energy physics. This lecture aims at defining the frontier of current comprehension in this field by some examples. First quarks and gluons are presented. Proofs of existence of pinpoint particles inside the nucleus are given. Then a direct proof of the concept validity of the nucleon orbit in the nucleus is given. Mesonic freedom degrees are also studied. Some experience examples in which meson exchange exist clearly are shown. At last, the role of subnucleonic effects in the nuclear reactions is shown [fr

    Making UK undergraduate physics degrees longer must have seemed like a good idea at the time. Back in the early 1990s the standard three-year Bachelor's physics degree (four years in Scotland) was under pressure at both ends. The A-level curriculum - one of the requirements for entry onto a degree course - was being increasingly modularized, and dumbed down. Physics students were arriving at university less well prepared than in the past and there was an increasing awareness that graduates of five-year continental degree courses were better equipped for a professional scientific career than those in the UK. At the same time, local education authorities in the UK were required to provide full funding for a first degree, whether for three or four years.

    According to the foundationalist picture, shared by many rationalists and positivist empiricists, science makes cognitive progress by accumulating justified truths. Fallibilists, who point out that complete certainty cannot be achieved in empirical science, can still argue that even successions of false theories may progress toward the truth. This proposal was supported by Karl Popper with his notion of truthlikeness or verisimilitude. Popper's own technical definition failed, but the idea that scientific progress means increasing truthlikeness can be expressed by defining degrees of truthlikeness in terms of similarities between states of affairs. This paper defends the verisimilitude approach against Alexander Bird who argues that the "semantic" definition (in terms of truth or truthlikeness alone) is not sufficient to define progress, but the "epistemic" definition referring to justification and knowledge is more adequate. Here Bird ignores the crucial distinction between real progress and estimated progress, explicated by the difference between absolute (and usually unknown) degrees of truthlikeness and their evidence-relative expected values. Further, it is argued that Bird's idea of returning to the cumulative model of growth requires an implausible trick of transforming past false theories into true ones.

    Wahlberg, Ayo

    2007-01-01

    In recent years, sociological examinations of genetics, therapeutic cloning, neuroscience and tissue engineering have suggested that 'life itself' is currently being transformed through technique with profound implications for the ways in which we understand and govern ourselves and others...... in much the same way that mortality rates, life expectancy or morbidity rates can. By analysing the concrete ways in which human progress has been globally measured and taxonomised in the past two centuries or so, I will show how global stratifications of countries according to their states...

  1. Progressivity Enhanced

    Directory of Open Access Journals (Sweden)

    Marko Hren

    2013-09-01

    Full Text Available Rather than a scientific text, the author contributes a concise memorandum from the originator of the idea who has managed the campaign for the conversion of the military barracks into a creative cluster between 1988 and 2002, when he parted ways with Metelkova due to conflicting views on the center’s future. His views shed light on a distant period of time from a perspective of a participant–observer. The information is abundantly supported by primary sources, also available online. However, some of the presented hypotheses are heavily influenced by his personal experiences of xenophobia, elitism, and predatorial behavior, which were already then discernible on the so-called alternative scene as well – so much so that they obstructed the implementation of progressive programs. The author claims that, in spite of the substantially different reality today, the myths and prejudices concerning Metelkova must be done away with in order to enhance its progressive nature. Above all, the paper calls for an objective view on internal antagonisms, mainly originating in deep class divisions between the users. These make a clear distinction between truly marginal ndividuals and the overambitious beau-bourgeois, as the author labels the large part of users of Metelkova of »his« time. On these grounds, he argues for a robust approach to ban all forms of xenophobia and self-ghettoization.

  3. Malthusian Progress

    DEFF Research Database (Denmark)

    Weisdorf, Jacob Louis

    is a theoretical demonstration that, even though a Malthusian society is inherently stagnant in the sense that sustained economic growth is absent, scattered advances in technology can permanently raise the long-term wage rate. The key reason why new technology can have a short-term as well as a long-term (i.......e. permanent) effect on the wage rate is the fact that a technological development can influence the degree to which the standard of living impacts upon birth and death rates. The second contribution of the dissertation is the empirical illustration that pre-industrial England, in spite of its Malthusian...... reallocation between sectors, and human capital investments – are features of development that are incompatible with the idea of Malthusian stagnation. These opponents also reject the idea that Malthusian forces drove English wage rates down to a biological minimum. The contest between the Malthusian and anti...

This paper sets up four different models of an imperfect labour market in order to identify the degree of tax......All modern labour market theories capable of explaining involuntary unemployment as an equilibrium phenomenon imply that increased income tax progressivity reduces unemployment, but they also imply that higher progressivity tends to reduce work effort and labour productivity. This suggests...

    The Astronautics Program (http://astronautics.usc.edu) of the University of Southern California (USC) offers a full set of undergraduate and graduate degree programs in Aerospace Engineering with emphasis in Astronautics. The Bachelor of Science degree program in Astronautics combines basic science and engineering classes with specialized astronautics classes. The Master of Science degree program in Astronautics offers classes in various areas of space technology. The Certificate in Astronautics targets practicing engineers and scientists who enter space-related fields and/or who want to obtain training in specific space-related areas. Many specialized graduate classes are taught by adjunct faculty working at the leading space companies. The Master of Science degree and Certificate are available through the USC Distance Education Network (DEN). Today, the Internet allows us to reach students anywhere in the world through webcasting. The majority of our graduate students, as well as those pursuing the Certificate, work full time as engineers in the space industry and government research and development centers. The new world of distance learning presents new challenges and opens new opportunities. We show how the transformation of distance learning and particularly the introduction of webcasting transform organization of the program and class delivery. We will describe in detail the academic focus of the program, student reach, and structure of program components. Program development is illustrated by the student enrollment dynamics and related industrial trends; the lessons learned emphasize the importance of feedback from the students and from the space industry.

    Continuous recording of vital physiological variables and sequential MR imaging were performed simultaneously during continuous expansion of an epidural rubber balloon over the left hemisphere in anaesthetised dogs. Balloon expansion led to a progressive and slgithly nonlinear rise in intracranial CSF pressures and a full in local perfusion pressures. Changes in systemic arterial pressure, pulse rate, and respiration rate usually appeared at a balloon volume of 4% to 5% of the intracranial volume (reaction volume), together with a marked transtentorial pressure gradient and MR imaging changes consistent with tentorial herniation. Respiratory arrest occurred at a balloon volume of approximately 10% of the intracranial volume (apnoea volume), which was associated with occulsion of the cisterna magna, consistent with some degree of foramen magnum herniation. Increase in tissue water was observed beginning at approximately the reaction volume, presumably due to ischaemic oedema, due to the fall in perfusion pressures. (orig.)

    Kim, Hyunju; Toroczkai, Zoltan; Erdos, Peter L; Miklos, Istvan; Szekely, Laszlo A

    2009-01-01

    Degree-based graph construction is a ubiquitous problem in network modelling (Newman et al 2006 The Structure and Dynamics of Networks (Princeton Studies in Complexity) (Princeton, NJ: Princeton University Press), Boccaletti et al 2006 Phys. Rep. 424 175), ranging from social sciences to chemical compounds and biochemical reaction networks in the cell. This problem includes existence, enumeration, exhaustive construction and sampling questions with aspects that are still open today. Here we give necessary and sufficient conditions for a sequence of nonnegative integers to be realized as a simple graph's degree sequence, such that a given (but otherwise arbitrary) set of connections from an arbitrarily given node is avoided. We then use this result to present a swap-free algorithm that builds all simple graphs realizing a given degree sequence. In a wider context, we show that our result provides a greedy construction method to build all the f-factor subgraphs (Tutte 1952 Can. J. Math. 4 314) embedded within K n setmn S k , where K n is the complete graph and S k is a star graph centred on one of the nodes. (fast track communication)

The main result is that every infinite sequence S with constructive Hausdorff dimension dim_H(S) and constructive packing dimension dim_P(S) is Turing equivalent to a sequence R with dim_H(R) 0. Furthermore, if dim_P(S) > 0, then dim_P(R) >= 1 - epsilon. The reduction thus serves as a *randomness extractor* that increases the algorithmic randomness of S, as measured by constructive dimension. A number of...

  15. Measurement of the oxidation of spent fuel between 140/degree/ and 225/degree/C by thermogravimetric analysis

    International Nuclear Information System (INIS)

    1988-09-01

    A series of PWR spent fuel samples from Turkey Point Unit 3 have been oxidized at temperatures between 140/degree/ and 225/degree/C in air atmospheres with dew points between 14.5/degree/ and /minus/70/degree/C, using a thermogravimetric analysis system (TGA). Tests lasted between 400 and 2100 hours. At the conclusion of a test, the atmosphere was sampled to determine the release of fission gas during testing, and the fuel samples were analyzed for microstructural changes. It appears that the mechanism for oxidation of spent fuel to U/sub 3/O/sub 7/ takes place in two steps that occur somewhat simultaneously. Oxygen migrates along the grain boundaries, which are oxidized and enlarged. The grains oxidize by the inward progression of a layer of U/sub 4/O/sub 9/ saturated with oxygen. A simplified model of the mechanism, which considers oxygen diffusion through the product layer as the rate-controlling step, yields an activation energy of 27 /plus minus/ 4 kcal/mol. Moisture, between dew points of /minus/70/degree/ to +14.5/degree/C, i.e., water vapor partial pressures varying over four orders of magnitude, had no significant effect on the oxidation rate. 34 refs., 12 figs., 6 tabs

    2012-10-01

    In the present work, we have compared the resistance of the 90 Degree-Sign , 180 Degree-Sign , and 360 Degree-Sign domain walls in the presence of external magnetic field. The calculations are based on the Boltzmann transport equation within the relaxation time approximation. One-dimensional Neel-type domain walls between two domains whose magnetization differs by angle of 90 Degree-Sign , 180 Degree-Sign , and 360 Degree-Sign are considered. The results indicate that the resistance of the 360 Degree-Sign DW is more considerable than that of the 90 Degree-Sign and 180 Degree-Sign DWs. It is also found that the domain wall resistance can be controlled by applying transverse magnetic field. Increasing the strength of the external magnetic field enhances the domain wall resistance. In providing spintronic devices based on magnetic nanomaterials, considering and controlling the effect of domain wall on resistivity are essential.

    The Chinese government launched a comprehensive healthcare reform to tackle challenges to health equities. Medical education will become the key for successful healthcare reform. We describe the current status of the Chinese medical degree system and its evolution over the last 80 years. Progress has been uneven, historically punctuated most dramatically by the Cultural Revolution. There is a great regional disparity. Doctors with limited tertiary education may be licensed to practice, whereas medical graduates with advanced doctorates may have limited clinical skills. There are undefined relationships between competing tertiary training streams, the academic professional degree, and the clinical residency training programme (RTP). The perceived quality of training in both streams varies widely across China. As the degrees of master or doctor of academic medicine is seen as instrumental in career advancement, including employability in urban hospitals, attainment of this degree is sought after, yet is often unrelated to a role in health care, or is seen as superior to clinical experience. Meanwhile, the practical experience gained in some prestigious academic institutions is deprecated by the RTP and must be repeated before accreditation for clinical practice. This complexity is confusing both for students seeking the most appropriate training, and also for clinics, hospitals and universities seeking to recruit the most appropriate applicants. The future education reforms might include: 1) a domestic system of 'credits' that gives weight to quality clinical experience vs. academic publications in career advancement, enhanced harmonisation between the competing streams of the professional degree and the RTP, and promotion of mobility of staff between areas of excellence and areas of need; 2) International - a mutual professional and academic recognition between China and other countries by reference to the Bologna Accord, setting up a system of easily comparable and

    International Nuclear Information System (INIS)

    2009-01-01

    The debate on degree education for radiographers began in earnest in the mid-1970s. Initially the debate hinged around whether a degree education was necessary for radiographers. One argument was that it was felt that a degree would separate academic and clinical training but eventually when degrees were introduced practical skills were assessed formally for the first time; something that had not been achieved with the Diploma of the College of Radiographers (DCR). The DCR itself became a barrier to degree education as the College of Radiographers (CoR) insisted that it was the only qualification recognised for state registration and as such would have to remain embedded as a distinct qualification within a degree. A major breakthrough came when the Council for National Academic Awards (CNAA) recognised the DCR at the same level as an ordinary degree. Around the same time the CoR published its Degree Rationale which announced a change in policy by not insisting that the DCR was sacrosanct. Developments followed rapidly and the first honours degree in radiography was validated in 1989 despite opposition from scientific officers at the Department of Health. Degrees were approved for state registration and radiography became a graduate profession by 1993 following years of debate and after overcoming opposition from both within and external to the profession.

    Unpolarized light is invariant with respect to any SU(2) polarization transformation. Since this fully characterizes the set of density matrices representing unpolarized states, we introduce the degree of polarization of a quantum state as its distance to the set of unpolarized states.

    In this paper we describe a novel approach for comparing users' spatial cognition when using different depictions of 360- degree video on a traditional 2D display. By using virtual cameras within a game engine and texture mapping of these camera feeds to an arbitrary shape, we were able to offer users a 360-degree interface composed of four 90-degree views, two 180-degree views, or one 360-degree view of the same interactive environment. An example experiment is described using these interfaces. This technique for creating alternative displays of wide-angle video facilitates the exploration of how compressed or fish-eye distortions affect spatial perception of the environment and can benefit the creation of interfaces for surveillance and remote system teleoperation.

  16. Progress in fusion

    International Nuclear Information System (INIS)

    1959-01-01

    Controlled thermonuclear fusion is now the biggest challenge before atomic science, not only because of the exceedingly difficult nature of the problem but also because of the virtually limitless benefit that, it is expected, will eventually flow from its solution. It might be pointed out that if some of the early optimism is now inevitably moderated, that is only because there is now a better understanding of the difficulties and, consequently, of the basic scientific and technical problems. The basic problem, as is now widely known, is to heat heavy hydrogen gas to a temperature at which the nuclei will fuse by moving so fast as to overcome their mutual electrical repulsion, and simultaneously to keep the gas in a state of extreme density so that the nuclei may collide against each other, fuse, release-energy in the form of heat, and thus set in a kind of thermal chain reaction. The temperature required is of a fantastically high order, but the scientists are confident that it can be obtained by fantastically powerful electrical discharges. More difficult seems to be the task of making the superheated gas, or the plasma as it is called when completely ionized, to behave obligingly. It must remain in a state of extreme density even when it is heated to a temperature of many millions of degrees. As a matter of fact, it must be contained, so to speak, by itself; it must not touch the walls of its material container and thereby lose some of its heat and, on top of that, evaporate the container. The pinch effect produces a kind of magnetic bottle for containing the plasma, but the trouble seems to be that it is difficult to make the bottle stable and leak-proof. The next task will be to ensure that the output of energy from this fusion is greater than the input of energy to heat the plasma. Intensive research and experiment on these problems have been going on in several countries, notably in the UK, the USA, and the USSR. In all the countries most advanced in

    After years of discussion, debate, and study, the respiratory care curriculum has evolved to a minimum of an associate degree for entry into practice. Although programs are at liberty to offer the entry-level or advanced level associate degree, most are at the advanced level. The most popular site for sponsorship of the associate degree in respiratory care is the community college. The basis for community college sponsorship seems to be its comprehensive curriculum, which focuses on a strong academic foundation in writing, communication, and the basic sciences as well as supporting a career-directed focus in respiratory care. Issues facing the community college are tied to literacy, outcomes, assessment, placement,cooperation with the community, partnerships with industry, and articulation arrangements with granting institutions granting baccalaureate degrees. Community colleges must produce a literate graduate capable of thriving in an information-saturated society. Assessment and placement will intensify as the laissez-faire attitudes toward attendance and allowing students to select courses without any accountability and evaluation of outcome become less acceptable. Students will be required to demonstrate steady progress toward established outcomes. Maintaining relations and cooperation with the local community and the health care industry will continue to be a prominent role for the community college. The challenge facing associate degree education in respiratory care at the community college level is the ability to continue to meet the needs of an expanding professional scope of practice and to provide a strong liberal arts or general education core curriculum. The needs for a more demanding and expanding respiratory care curriculum and for a rich general education core curriculum have led to increased interest in baccalaureate and graduate degree education. The value of associate degree education at the community college level is well established. It is

    The future challenges to medical and biological engineering, sometimes referred to as biomedical engineering or simply bioengineering, are many. Some of these are identifiable now and others will emerge from time to time as new technologies are introduced and harnessed. There is a fundamental issue regarding "Branding the bio/biomedical engineering degree" that requires a common understanding of what is meant by a B.S. degree in Biomedical Engineering, Bioengineering, or Biological Engineering. In this paper we address some of the issues involved in branding the Bio/Biomedical Engineering degree, with the aim of clarifying the Bio/Biomedical Engineering brand.

    This paper discusses the advantages of progress testing. A utopia is described where medical schools would work together to develop and administer progress testing. This would lead to a significant reduction of cost, an increase in the quality of measurement and phenomenal feedback to learner and school. Progress testing would also provide more freedom and resources for more creative in-school assessment. It would be an educationally attractive alternative for the creation of cognitive licensing exams. A utopia is always far away in the future, but by formulating a vision for that future we may engage in discussions on how to get there.

To date, there have been limited attempts to identify individual differences in motivation that drive the undergraduate degree choice. We identified that people choose university degrees for four reasons: career concerns (Career, intrinsic interest (Interest in the subject, an opportunity to help others (Helping and because they are looking for an easy option into higher education (Loafing. We investigated whether these motivation apply to the choice of undergraduate degree in two samples: (1 undergraduate (N = 989 and (2 prospective (N = 896 students. We developed the Motivations Influencing Course Choice (MICC questionnaire to measure these motivations. Scales of Helping, Career, Loafing and Interest showed good psychometric properties, showed validity with respect to general life goals and personality traits, and predicted actual and prospective degree choices. We demonstrated that medical degrees were chosen due to a mixture of Helping and Career, while engineering degrees were associated with Career and low interest in the degree. The choice of art and humanities degrees was driven by Interest and low concern about future career, accompanied with high Loafing. We also demonstrated gender differences: females were high in Helping (both samples and Interest (only in undergraduate sample motivation, while males scored higher in Career (only in undergraduate sample and Loafing (both samples. The findings can feed into both theoretical accounts of proximal motivation as well as help to improve degree programmes at universities and provide better career advice.

    2006-01-01

    The study of nuclear reaction dynamics and thermodynamics with nuclear degrees of freedom has progressed dramatically in the past 20 years, from inclusive charge distributions to exclusive isotopically resolved fragment observables and from schematic phenomenological break-up models to sophisticated quantum many-body transport theories. A coherent and quantitative understanding of reaction mechanisms and of the underlying nuclear matter equation of state is emerging from the analysis of experimental data and from the theoretical modeling of heavy ion reactions. In addition, the accumulated evidence for phenomena related to the liquid-gas phase transition of nuclear matter has triggered interdisciplinary activities and the transfer of useful methods. In the near future, the availability of radioactive beam facilities is expected to provide unique opportunities for extending our knowledge of the dynamic properties and the nuclear phase diagram towards exotic nuclear systems with important astrophysical implicat...

  5. High-Degree Neurons Feed Cortical Computations.

    2016-05-01

    Full Text Available Recent work has shown that functional connectivity among cortical neurons is highly varied, with a small percentage of neurons having many more connections than others. Also, recent theoretical developments now make it possible to quantify how neurons modify information from the connections they receive. Therefore, it is now possible to investigate how information modification, or computation, depends on the number of connections a neuron receives (in-degree or sends out (out-degree. To do this, we recorded the simultaneous spiking activity of hundreds of neurons in cortico-hippocampal slice cultures using a high-density 512-electrode array. This preparation and recording method combination produced large numbers of neurons recorded at temporal and spatial resolutions that are not currently available in any in vivo recording system. We utilized transfer entropy (a well-established method for detecting linear and nonlinear interactions in time series and the partial information decomposition (a powerful, recently developed tool for dissecting multivariate information processing into distinct parts to quantify computation between neurons where information flows converged. We found that computations did not occur equally in all neurons throughout the networks. Surprisingly, neurons that computed large amounts of information tended to receive connections from high out-degree neurons. However, the in-degree of a neuron was not related to the amount of information it computed. To gain insight into these findings, we developed a simple feedforward network model. We found that a degree-modified Hebbian wiring rule best reproduced the pattern of computation and degree correlation results seen in the real data. Interestingly, this rule also maximized signal propagation in the presence of network-wide correlations, suggesting a mechanism by which cortex could deal with common random background input. These are the first results to show that the extent to

    The current impact of adolescent obesity on educational attainment is not clear. The objectives of our study were to determine whether adolescent obesity is associated with college degree attainment and how this association may have changed over time. We used data from a contemporary national cohort of over 4,000 persons who were adolescents (aged 14-18) in 1997 to assess the relationship between adolescent obesity and education. To assess for changes in this relationship over time, we also analyzed an older, similarly structured cohort of over 3,000 persons who were adolescents (aged 16-18) in 1981. Our primary outcome was college degree completion. We found that in the older cohort (adolescents in 1979), there were no differences in college degree attainment by adolescent weight status before and after adjustment. However, unadjusted analysis of the contemporary cohort (adolescents in 1997) demonstrated that those who were normal weight as adolescents had a higher prevalence of college degree attainment at follow-up compared to obese adolescents (24% vs. 10%). After adjustment for socio-demographic variables (age, sex, race, height, parental income-to-poverty ratio, parental education, aptitude test scores), obese adolescents were less likely to have attained a college degree compared to normal weight peers (adjusted risk ratio 0.61 95% confidence interval 0.38-0.83). Expectations for a future college degree did not vary by weight status and did not explain this observation. In conclusion, adolescent obesity is associated with lower likelihood of college completion. This relationship was not observed in an older cohort of adolescents.

However, taking gravity into account (as for, instance, in the study of neutron stars), most authors do not take into account the relation between hyperbolic geometry and spin and derive an Einstein equation which implicitly takes into account only boson degrees of freedom. In this work we introduce a consistent quantum general relativistic formalism which allows us to study the effects of the existence of fermion degrees of freedom. (author)

    Full-disk observations taken with the Michelson Doppler Imager (MDI) on board the Solar and Heliospheric Observatory (SOHO) spacecraft, or the upgraded Global Oscillations Network Group (GONG) instruments, have enough spatial resolution to resolve modes up to {iota} = 1000 if not {iota} = 1500. The inclusion of such high-degree modes (i.e., {iota} {<=} 1000) improves dramatically inferences near the surface. Unfortunately, observational and instrumental effects cause the characterization of high degree modes to be quite complicated. Indeed, the characteristics of the solar acoustic spectrum are such that, for a given order, mode lifetimes get shorter and spatial leaks get closer in frequency as the degree of a mode increases. A direct consequence of this property is that individual modes are resolved only at low and intermediate degrees. At high degrees the individual modes blend into ridges and the power distribution of the ridge defines the ridge central frequency, masking the underlying mode frequency. An accurate model of the amplitude of the peaks that contribute to the ridge power distribution is needed to recover the underlying mode frequency from fitting the ridge. We present a detailed discussion of the modeling of the ridge power distribution, and the contribution of the various observational and instrumental effects on the spatial leakage, in the context of the MDI instrument. We have constructed a physically motivated model (rather than an ad hoc correction scheme) that results in a methodology that can produce unbiased estimates of high-degree modes. This requires that the instrumental characteristics are well understood, a task that has turned out to pose a major challenge. We also present our latest results, where most of the known instrumental and observational effects that affect specifically high-degree modes were removed. These new results allow us to focus our attention on changes with solar activity. Finally, we present variations of mode

    Progressive visual agnosia was discovered in the 20th century following the discovery of classical non-progressive visual agnosia. In contrast to the classical type, which is caused by cerebral vascular disease or traumatic injury, progressive visual agnosia is a symptom of neurological degeneration. The condition of progressive visual loss, including visual agnosia, and posterior cerebral atrophy was named posterior cortical atrophy (PCA) by Benson et al. (1988). Progressive visual agnosia is also observed in semantic dementia (SD) and other degenerative diseases, but there is a difference in the subtype of visual agnosia associated with these diseases. Lissauer (1890) classified visual agnosia into apperceptive and associative types, and it in most cases, PCA is associated with the apperceptive type. However, SD patients exhibit symptoms of associative visual agnosia before changing to those of semantic memory disorder. Insights into progressive visual agnosia have helped us understand the visual system and discover how we "perceive" the outer world neuronally, with regard to consciousness. Although PCA is a type of atypical dementia, its diagnosis is important to enable patients to live better lives with appropriate functional support.

    2010-01-01

    We examine various second-degree difference equations which have been proposed over the years and according to their authors' claims should be integrable. This study is motivated by the fact that we consider that second-degree discrete systems cannot be integrable due to the proliferation of the images (and pre-images) of the initial point. We show that in the present cases no contradiction exists. In all cases examined, we show that there exists an underlying integrable first-degree mapping which allows us to obtain an appropriate solution of the second-degree one.

  16. Interpretability degrees of finitely axiomatized sequential theories

    2004-01-01

    The Astronautics Program (http://astronautics.usc.edu) of the University of Southern California (USC) offers a full set of undergraduate and graduate degree programs in Aerospace Engineering with emphasis in Astronautics. The Bachelor of Science and Master of Science degree programs in Astronautics combine basic science and engineering classes with specialized classes in space technology. The Certificate in Astronautics targets practicing engineers and scientists who enter space-related fields and/or who want to obtain training in specific space-related areas. Many specialized graduate classes are taught by adjunct faculty working at the leading space companies. The Master of Science degree and Certificate are available entirely through the USC Distance Education Network (DEN). Today, the Internet allows us to reach students anywhere in the world through webcasting. The majority of our graduate students, as well as those pursuing the Certificate, work full time as engineers in the space industry and government research and development centers while earning their degrees. The new world of distance learning presents new challenges and opens new opportunities. Distance learning, and particularly the introduction of webcasting, transform the organization of the graduate program and class delivery. We describe in detail the program's academic focus, student reach, and structure of program components. Program development is illustrated by the student enrollment dynamics and related industrial trends; the lessons learned emphasize the importance of feedback from the students and from the space industry.

    Health care has become very complex and is in a constant state of change. As a result of the evolving change and increasing complexity, a more educated nursing workforce is needed (Dracup K. Master's nursing programs. American Association of Colleges of Nursing. 2015; Institute of Medicine. The Future of Nursing: Leading Change, Advancing Health. 2010). It is now becoming necessary for registered nurses to earn an advanced degree to work at the highest level of their practice authority (Dracup K. Master's nursing programs. American Association of Colleges of Nursing. 2015; Institute of Medicine. The Future of Nursing: Leading Change, Advancing Health. 2010.). Preparing to reenter college may be an overwhelming prospect for some registered nurses seeking an advanced degree. However, there are some simple strategies that may help sort out the many degree options, financial obligations, decisions about brick and mortar versus online learning, commitment to degree completion, and changing career paths. This article will provide the registered nurse valuable information that will assist in the exciting process of returning to college.

  16. Pions and other hadronic degrees of freedom in nuclei

    International Nuclear Information System (INIS)

    Brockmann, B.; Weise, W.

    1985-01-01

    As ≥E and or ≥q is increased up to several hundreds of MeV, the explicit mesonic degrees of freedom become directly visible. The pion, in particular, is of fundamental importance. With its small mass of m/sub π/ = 140 MeV it is by far the lightest of all mesons. It is the generator of the long range nucleon-nucleon interaction. The pion Compton wavelength psi/sub π/ = Κm/sub π/c = 1.4 fm, defines the length scale of nuclear physics. As mesons become important, nucleons begin to reveal their intrinsic structure. Inseparably connected with pionic degrees of freedom is the role of the Δ(1232), the spin 3/2-isopin 3/2 isobar reached from the nucleon by a strong spin-isopin transition at an excitation energy ΔE = M/sub Δ/ - M ≅ 300 MeV, the Δ-nucleon mass difference. This paper, the position is taken that the nucleus consists of nucleons and their excited states (primarily the ≥ (1232)) which communicate by exchange of mesons (in particular: the pion). Such a description has turned out to be quite successful in correlating various phenomena and data at intermediate energies, remarkably though without the need, so far, for explicit reference to underlying quark degrees of freedom. This progress has gone parallel with the similarly successful meson exchange phenomenology of nucleon-nucleon forces at long and intermediate distances (r ≥ 0.8 fm)

    in patient care, they have not dealt specifically with the role, structure, and content of the progress notes. As a consequence, CSCW research has not yet taken fully into account the fact that progress notes are coordinative artifacts of a rather special kind, an open-ended chain of prose texts, written...... sequentially by cooperating physicians for their own use as well as for that of their colleagues. We argue that progress notes are the core of the medical record, in that they marshal and summarize the overwhelming amount of data that is available in the modern hospital environment, and that their narrative...... format is uniquely adequate for the pivotal epistemic aspect of cooperative clinical work: the narrative format enables physicians to not only record ‘facts’ but also—by filtering, interpreting, organizing, and qualifying information—to make sense and act concertedly under conditions of uncertainty...

  2. Chronic progressive multiple sclerosis

    1991-01-01

    A long-lasting immunological suppression action seems to be produced by total lymphoid irradiation; some authors emphasize the favorable effect of this treatment on chronic progressive multiple sclerosis. In order to evaluate the actual role of TLI, 6 patients affected with chronic progressive multiple sclerosis were submitted to TLI with shaped and personalized fields at the Istituto del Radio, University of Brescia, Italy. The total dose delivered was 19.8 Gy in 4 weeks, 1.8 Gy/day, 5d/w; a week elapsed between the first and the second irradiation course. Disability according to Kurtzke scale was evaluated, together with blood lymphocyte count and irradiation side-effects, over a mean follow-up period of 20.8 months (range: 13-24). Our findings indicate that: a) disease progression was not markedly reduced by TLI; b) steroid hormones responsivity was restored after irradiation, and c) side-effects were mild and tolerable

  8. Nuclear diffuseness as a degree of freedom

    Science.gov (United States)

    Myers, W. D.; ŚwiaŢecki, W. J.

    1998-12-01

    The response of the nuclear energy to changes in neutron and proton surface diffusenesses is investigated using the Thomas-Fermi model. Algebraic expressions are provided for the energy cost of changing the two diffusenesses away from their equilibrium values. This will make it possible to generalize the macroscopic-microscopic calculations of nuclear masses and deformation energies by the inclusion of the neutron and proton diffusenesses as degrees of freedom (to be varied along with the shape degrees of freedom). One result, which is suggested by the relatively low cost in macroscopic energy of increasing the diffuseness of a heavy nucleus by 10% (about 4 MeV), is that superheavy nuclei near Z=126, N=184 may have a fair chance of becoming stabilized by shell effects. An appendix introduces an improved measure of surface diffuseness, with certain advantages over the conventional Süssmann width b.

    International Nuclear Information System (INIS)

    Pastore y Piontti, Ana L.; Braunstein, Lidia A.; Macri, Pablo A.

    2010-01-01

    We study the effects of the degree-degree correlations on the pressure congestion J when we apply a dynamical process on scale free complex networks using the gradient network approach. We find that the pressure congestion for disassortative (assortative) networks is lower (bigger) than the one for uncorrelated networks which allow us to affirm that disassortative networks enhance transport through them. This result agree with the fact that many real world transportation networks naturally evolve to this kind of correlation. We explain our results showing that for the disassortative case the clusters in the gradient network turn out to be as much elongated as possible, reducing the pressure congestion J and observing the opposite behavior for the assortative case. Finally we apply our model to real world networks, and the results agree with our theoretical model.

  10. Effective hadron degrees of freedom in nuclei

    International Nuclear Information System (INIS)

    Mulders, P.J.

    1988-01-01

    This paper discusses several topics. The first one is the importance of a consistent treatment of extended nucleons and the subsequent requirement of accounting for quark antisymmetrization. It will probably be possible to account for these effects through quark exchange currents in much of the same way as meson exchange currents at lower values of Q 2 . In order to obtain more definite answers on intrinsic properties of nucleons and other hadronic degrees of freedom in nuclei it is important to establish to which extent hadronic degrees of freedom behaving like quasi-free nuclear constituents can be used to describe the nuclear response in inclusive and semi-inclusive electron scattering at intermediate energies

  12. Isobar degrees of freedom in nuclei

    International Nuclear Information System (INIS)

    Muether, H.

    1979-01-01

    A report is given on some recent investigations of the influence of isobar degrees of freedom on the ground state properties of finite nuclei like e.g. 16 O. The nucleon-nucleon (NN) interaction is constructed in the freamework of an extended one-boson-exchange (OBE) model using non-covariant, time-dependent perturbation theory. The explicit consideration of fourth-order iterative diagrams involving NΔ and ΔΔ intermediate states gives an effective NN interaction in the nuclear many-body system which is less attractive than those which are obtained treating these terms phenomenologically. Therefore the binding energy calculated in the Brueckner-Hartree-Fock approximation is smaller if these effects of isobar degrees of freedom are taken into account. This repulsive effect of isobar configurations is partly counterbalanced by the attraction obtained for three-nucleon terms with intermediate NNΔ states. (Auth.)

  13. The physical gravitational degrees of freedom

    International Nuclear Information System (INIS)

    Anderson, E; Barbour, J; Foster, B Z; Kelleher, B; Murchadha, N O

    2005-01-01

    When constructing general relativity (GR), Einstein required 4D general covariance. In contrast, we derive GR (in the compact, without boundary case) as a theory of evolving three-dimensional conformal Riemannian geometries obtained by imposing two general principles: (1) time is derived from change; (2) motion and size are relative. We write down an explicit action based on them. We obtain not only GR in the CMC gauge, in its Hamiltonian 3 + 1 reformulation, but also all the equations used in York's conformal technique for solving the initial-value problem. This shows that the independent gravitational degrees of freedom obtained by York do not arise from a gauge fixing but from hitherto unrecognized fundamental symmetry principles. They can therefore be identified as the long-sought Hamiltonian physical gravitational degrees of freedom

To assess for changes in this relationship over time, we also a...

  18. Depth and degree of melting of komatiites

    Science.gov (United States)

    Herzberg, Claude

    1992-04-01

    High pressure melting experiments have permitted new constraints to be placed on the depth and degree of partial melting of komatiites. Komatiites from Gorgona Island were formed by relatively low degrees of pseudoinvariant melting involving L + Ol + Opx + Cpx + Gt on the solidus at 40 kbar, about 130 km depth. Munro-type komatiites were separated from a harzburgite residue (L + Ol + Opx) at pressures that were poorly constrained, but were probably around 50 kbar, about 165 km depth; the degree of partial melting was less than 40 percent. Secular variations in the geochemistry of komatiites could have formed in response to a reduction in the temperature and pressure of melting with time. The 3.5 Ga Barberton komatiites and the 2.7 Ga Munro-type komatiities could have formed in plumes that were hotter than the present-day mantle by 500 deg and 300 deg, respectively. When excess temperatures are this size, melting is deeper and volcanism changes from basaltic to momatiitic. The komatiities from Gorgona Island, which are Mesozoic in age, may be representative of komatiities that are predicted to occur in oceanic plateaus of Cretaceous age throughout the Pacific (Storey et al., 1991).

    Full Text Available Purpose — the purpose of this article is to extend discussion towards the need and importance of joint degree programs in modern universities, introducing the perspective of the employers toward this question. Design/methodology/approach — the research was conducted to analyze the demand of joint degree programs from the perspective of employers, identify weak and strong aspects, opinion and demand for graduates of such programs. To achieve this purpose, a combination of theoretical and empirical methods was chosen: document analysis (previous studies, statistics was conducted and an online qualitative survey was organized. Findings — The analysis of articles, studies and statistics points out the challenges and threats faced by universities nowadays, forcing higher education institutions to find new ways to raise the quality of studies and raise the interest of employers to choose graduates from MRU, as well as the satisfaction of employers with their choice of employees. Theoretical analysis pointed out these challenges and requirements for the modern employee, summarised the challenges in preparation of IT field specialists. The conducted research results showed that the diploma of joint degree programs would not be treated as an advantage of possible employee from the perspective of employers in case some important aspects will not be taken into consideration by program creators. On the other hand, undeniably there are strong sides, such as knowledge in the fields of foreign language, international experience, innovativeness and creativeness of employees that would be treated as an advantage in the process of selection for positions of any technical support related positions. Research limitations/implications — employers, whose business activities are closely related to information technology, have been invited as experts. In addition, these experts have a good understanding of the specifics of joint degree programs. The received

    Full Text Available På baggrund af en kvalitativ interviewundersøgelse af undervisere ved Aarhus Universitet lavet i 2012, tematiserer artiklen, hvordan undervisere udvikler deres faglige og pædagogiske kompetencer i forhold til at kunne skabe progression inden for innovation og entreprenørskab forstået enten som didaktik, arbejdsformer i faglige forløb eller som fag på universitetet. I arbejdet med progression er det en udfordring at integrere de nye faglige dimensioner i det kernefaglige felt. Den seneste model for progression inden for innovation og entreprenør-skab siger, at det er den lærendes generelle erfaringsniveau, der er den afgørende progressionsskabende faktor (Progressionsmodellen, Fonden for Entreprenørskab, 2013b. Samtidig skelner international forskning inden for studiekompetenceområdet mellem niveauer, hvor indlejret viden er det mest avancerede kompetenceniveau (Barrie, 2002.Ifølge progressionsmodellen og den nævnte kompetenceforskning er erfaring og dybt integreret læring altså centrale dimensioner i progression. Men hvad er underviserens rolle heri? Underviserens professionelle udviklingsarbejde forekommer at være underbelyst i forhold til, at underviseren er den legitime garant for integrationen af nye faglige dimensioner og for den studerendes kompetenceniveau. Interviewundersøgelsen forholder sig til spørgsmålet om progression gennem de deltagende underviseres beskrivelse af betydningslag i entreprenørskabsbegrebet koblet til de praksisformer i undervisningen, der knytter sig hertil samt et indblik i undervisernes refleksioner over deres kompetenceudviklingsprocesser. Artiklens bidrag til progression er at se underviserens motivation og kompetenceudvikling som forudsætninger herfor.     Based on a qualitative study of five teachers in the Faculty of Arts at Aarhus University that took place during 2012, the article thematizes how teachers develop their professional and educational qualifications in innovation and

    "A human capital framework is utilized to examine the economic progress of nine nationality groups of foreign workers [in Kuwait] using data from the 1983 national Labor Survey. The sources of earnings' variations of particular interest to us included different degrees of education and experience transferability, occupational affiliation and ethnic background. In general, the results derived from the analysis suggest that 1) foreign workers achieve a discernible economic progress as their residence lengthens; 2) the rate of economic progress varies depending on worker's education, home and Kuwait-specific experience, occupational status and ethnic background; and 3) about one third of the earnings inequality is due to unexplained factors including discrimination." excerpt

    To define variables for the evaluation of keratoconus progression and to determine cut-off values. In this retrospective cohort study (2010-2016), 265 eyes of 165 patients diagnosed with keratoconus underwent two Scheimpflug measurements (Pentacam) that took place 1 year apart ±3 months. Variables used for keratoconus detection were evaluated for progression and a correlation analysis was performed. By logistic regression analysis, a keratoconus progression index (KPI) was defined. Receiver-operating characteristic curve (ROC) analysis was performed and Youden Index calculated to determine cut-off values. Variables used for keratoconus detection showed a weak correlation with each other (eg, correlation r=0.245 between RPImin and Kmax, pKPI). KPI was defined by logistic regression and consisted of a Pachymin coefficient of -0.78 (p=0.001), a maximum elevation of back surface coefficient of 0.27 and coefficient of corneal curvature at the zone 3 mm away from the thinnest point on the posterior corneal surface of -12.44 (both pKPI: D-index had a cut-off of 0.4175 (70.6% sensitivity) and Youden Index of 0.606. Cut-off for KPI was -0.78196 (84.7% sensitivity) and a Youden Index of 0.747; both 90% specificity. Keratoconus progression should be defined by evaluating parameters that consider several corneal changes; we suggest D-index and KPI to detect progression. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Two bubble column sequencing batch reactors fed with an artificial wastewater were operated at 20 degrees C, 30 degrees C, and 35 degrees C. In a first stage, stable granules were obtained at 20 degrees C, whereas fluffy structures were observed at 30 degrees C. Molecular analysis revealed high abundance of the operational taxonomic unit 208 (OTU 208) affiliating with filamentous bacteria Leptothrix spp. at 30 degrees C, an OTU much less abundant at 20 degrees C. The granular sludge obtained at 20 degrees C was used for the second stage during which one reactor was maintained at 20 degrees C and the second operated at 30 degrees C and 35 degrees C after prior gradual increase of temperature. Aerobic granular sludge with similar physical properties developed in both reactors but it had different nutrient elimination performances and microbial communities. At 20 degrees C, acetate was consumed during anaerobic feeding, and biological phosphorous removal was observed when Rhodocyclaceae-affiliating OTU 214 was present. At 30 degrees C and 35 degrees C, acetate was mainly consumed during aeration and phosphorous removal was insignificant. OTU 214 was almost absent but the Gammaproteobacteria-affiliating OTU 239 was more abundant than at 20 degrees C. Aerobic granular sludge at all temperatures contained abundantly the OTUs 224 and 289 affiliating with Sphingomonadaceae indicating that this bacterial family played an important role in maintaining stable granular structures.

    In this talk, I would like to examine our present view on non-nucleonic degrees of freedom with a few typical experimental results obtained recently both with hadronic and electromagnetic probes at intermediate energies. It is the first generation of experimental data which has probed mesonic degrees of freedom with a spatial resolution of the order of 0.5 fm. This has made possible for example the measurement of the size of the pion-nucleon interaction region. This is very stimulating progress and we begin to have a coherent overview on the various reaction mechanisms which are induced by hadronic and electromagnetic probes

    Electron spin attracts much attention as an alternative to the electron charge degree of freedom for low-power reprogrammable logic and non-volatile memory applications. Silicon appears to be the perfect material for spin-driven applications. Recent progress and challenges regarding spin-based devices are reviewed. An order of magnitude enhancement of the electron spin lifetime in silicon thin films by shear strain is predicted and its impact on spin transport in SpinFETs is discussed. A relatively weak coupling between spin and effective electric field in silicon allows magnetoresistance modulation at room temperature, however, for long channel lengths. Due to tunneling magnetoresistance and spin transfer torque effects, a much stronger coupling between the spin (magnetization) orientation and charge current is achieved in magnetic tunnel junctions. Magnetic random access memory (MRAM) built on magnetic tunnel junctions is CMOS compatible and possesses all properties needed for future universal memory. Designs of spin-based non-volatile MRAM cells are presented. By means of micromagnetic simulations it is demonstrated that a substantial reduction of the switching time can be achieved. Finally, it is shown that any two arbitrary memory cells from an MRAM array can be used to perform a logic operation. Thus, an intrinsic non-volatile logic-in-memory architecture can be realized.

    NASA's Lewis Research Center is actively involved in the development of monolithic microwave and millimeter-wave integrated circuits (MMICs). The approach of the program is to support basic research under grant or in-house, while MMIC development is done under contract, thereby facilitating the transfer of technology to users. Preliminary thrusts of the program have been the extension of technology to higher frequencies (60 GHz), degrees of complexity, and performance (power, efficiency, noise figure) by utilizing novel circuit designs, processes, and materials. A review of the progress made so far is presented.

    Radiologists serve in leadership roles throughout their career, making leadership education an integral part of their development. A maxim of leadership style is summarized by 360-Degree Leadership, which highlights the ability of a leader to lead from any position within the organization while relying on core characteristics to build confidence from within their team. The qualities of leadership discussed can be learned and applied by radiologists at any level. These traits can form a foundation for the leader when faced with unfavorable events, which themselves allow the leader an opportunity to build trust. Copyright © 2017 American College of Radiology.

A recent extension by Karrer and Newman [Karrer and Newman...... corrected stochastic block model as a nonparametric Bayesian model, incorporating a parameter to control the amount of degree correction that can then be inferred from data. Additionally, our formulation yields principled ways of inferring the number of groups as well as predicting missing links...

  12. Importance of small-degree nodes in assortative networks with degree-weight correlations

    Science.gov (United States)

    Ma, Sijuan; Feng, Ling; Monterola, Christopher Pineda; Lai, Choy Heng

    2017-10-01

    It has been known that assortative network structure plays an important role in spreading dynamics for unweighted networks. Yet its influence on weighted networks is not clear, in particular when weight is strongly correlated with the degrees of the nodes as we empirically observed in Twitter. Here we use the self-consistent probability method and revised nonperturbative heterogenous mean-field theory method to investigate this influence on both susceptible-infective-recovered (SIR) and susceptible-infective-susceptible (SIS) spreading dynamics. Both our simulation and theoretical results show that while the critical threshold is not significantly influenced by the assortativity, the prevalence in the supercritical regime shows a crossover under different degree-weight correlations. In particular, unlike the case of random mixing networks, in assortative networks, the negative degree-weight correlation leads to higher prevalence in their spreading beyond the critical transmissivity than that of the positively correlated. In addition, the previously observed inhibition effect on spreading velocity by assortative structure is not apparent in negatively degree-weight correlated networks, while it is enhanced for that of the positively correlated. Detailed investigation into the degree distribution of the infected nodes reveals that small-degree nodes play essential roles in the supercritical phase of both SIR and SIS spreadings. Our results have direct implications in understanding viral information spreading over online social networks and epidemic spreading over contact networks.

    Full Text Available Abstract Progressive posterior cortical dysfunction (PPCD is an insidious syndrome characterized by prominent disorders of higher visual processing. It affects both dorsal (occipito-parietal and ventral (occipito-temporal pathways, disturbing visuospatial processing and visual recognition, respectively. We report a case of a 67-year-old woman presenting with progressive impairment of visual functions. Neurologic examination showed agraphia, alexia, hemispatial neglect (left side visual extinction, complete Balint's syndrome and visual agnosia. Magnetic resonance imaging showed circumscribed atrophy involving the bilateral parieto-occipital regions, slightly more predominant to the right . Our aim was to describe a case of this syndrome, to present a video showing the main abnormalities, and to discuss this unusual presentation of dementia. We believe this article can contribute by improving the recognition of PPCD.

    2014-03-01

    A feature of a network known to affect its structural and dynamical properties is the presence of correlations amongst the node degrees. Degree correlations are a measure of how much the connectivity of a node influences the connectivity of its neighbours, and they are fundamental in the study of processes such as the spreading of information or epidemics, the cascading failures of damaged systems and the evolution of social relations. We introduce a method, based on novel mathematical results, that allows the exact sampling of networks where the number of connections between nodes of any given connectivity is specified. Our algorithm provides a weight associated to each sample, thereby allowing network observables to be measured according to any desired distribution, and it is guaranteed to always terminate successfully in polynomial time. Thus, our new approach provides a preferred tool for scientists to model complex systems of current relevance, and enables researchers to precisely study correlated networks with broad societal importance.

  16. High degree-of-freedom dynamic manipulation

    Murphy, Michael P.; Stephens, Benjamin; Abe, Yeuhi; Rizzi, Alfred A.

    2012-06-01

    The creation of high degree of freedom dynamic mobile manipulation techniques and behaviors will allow robots to accomplish difficult tasks in the field. We are investigating the use of the body and legs of legged robots to improve the strength, velocity, and workspace of an integrated manipulator to accomplish dynamic manipulation. This is an especially challenging task, as all of the degrees of freedom are active at all times, the dynamic forces generated are high, and the legged system must maintain robust balance throughout the duration of the tasks. To accomplish this goal, we are utilizing trajectory optimization techniques to generate feasible open-loop behaviors for our 28 dof quadruped robot (BigDog) by planning the trajectories in a 13 dimensional space. Covariance Matrix Adaptation techniques are utilized to optimize for several criteria such as payload capability and task completion speed while also obeying constraints such as torque and velocity limits, kinematic limits, and center of pressure location. These open-loop behaviors are then used to generate feed-forward terms, which are subsequently used online to improve tracking and maintain low controller gains. Some initial results on one of our existing balancing quadruped robots with an additional human-arm-like manipulator are demonstrated on robot hardware, including dynamic lifting and throwing of heavy objects 16.5kg cinder blocks, using motions that resemble a human athlete more than typical robotic motions. Increased payload capacity is accomplished through coordinated body motion.

  17. The True Gravitational Degrees Of Freedom

    International Nuclear Information System (INIS)

    Murchadha, N. o

    2011-01-01

    More than 50 years ago it was realized that General Relativity could be expressed in Hamiltonian form. Unfortunately, just like electromagnetism and Yang-Mills theory, the Einstein equations split into evolution equations and constraints which complicates matters. The 4 constraints are expressions of the gauge freedom of the theory, general covariance. One can cleanly pose initial data for the gravitational field, but this data has to satisfy the constraints. To find the independent degrees of freedom, one needs to factor the initial data by the constraints. There are many ways of doing this. I can do so in such a way as to implement the model suggested by Poincare for a well-posed dynamical system: Pick a configuration space and give the free initial data as a point of the configuration space and a tangent vector at the same point. Now, the evolution equations should give a unique curve in the same configuration space. This gives a natural definition of what I call the true gravitational degrees of freedom. (author)

    Full Text Available Networks have an important place in our daily lives. Internet networks, electricity networks, water networks, transportation networks, social networks and biological networks are some of the networks we run into every aspects of our lives. A network consists of centers connected by links. A network is represented when centers and connections modelled by vertices and edges, respectively. In consequence of the failure of some centers or connection lines, measurement of the resistance of the network until the communication interrupted is called vulnerability of the network. In this study, neighbor rupture degree which is a parameter that explores the vulnerability values of the resulting graphs due to the failure of some centers of a communication network and its neighboring centers becoming nonfunctional were applied to some middle graphs and neighbor rupture degree of the $M(C_{n},$ $M(P_{n},$ $M(K_{1,n},$ $M(W_{n},$ $M(P_{n}\\times K_{2}$ and $M(C_{n}\\times K_{2}$ have been found.

    The precise relation between the gauge transformations in lagrangian and hamiltonian form is derived for any gauge theory. It is found that in order to define a lagrangian gauge symmetry, the coefficients of the first class constraints in the hamiltonian generator of gauge transformations must obey a set of differential equations. Those equations involve, in general, the Lagrange multipliers. Their solution contains as many arbitrary functions of time as there are primary first class constraints. If n is the number of generations of constraints (primary, secondary, tertiary...), the arbitrary functions appear in the general solution together with their successive time derivatives up to order n-1. The analysis yields as by-products: (i) a systematic way to derive all the gauge symmetries of a given lagrangian; (ii) a precise criterion for counting the physical degrees of freedom of a gauge theory directly from the form of gauge transformations in lagrangian form. This last part is illustrated by means of examples. The BRST analog of the counting of physical degrees of freedom is also discussed. (orig.)

  20. Device for measuring a burnup degree

    1979-01-01

    Purpose: To measure the burnup degree at high efficiency and accuracy. Constitution: The outer metal wall of fuel assemblies is heated under gamma radiation with long half life gamma rays in inverse proportion to the burnup degree and issues infrared radiation in proportion to the intensity of the gamma rays. An image pick-up tube is opposed to one surface of the fuel assemblies to detect the radiated infrared rays. Since the output signal from the pick-up tube is subjected to the absorptive damping by the distance between the pick-up tube and the fuel assembly, as well as water filled in the gap therebetween, it is corrected through a main amplifier comprising a signal correction circuit composed of a characteristic section inverse to the absorption property and a characteristic section inverse to the square of the distance. The corrected output signal is displayed on a display unit such as CRT or recorded in a film or a magnetic tape. (Furukawa, Y.)

  1. Epidemic spreading on preferred degree adaptive networks.

    We study the standard SIS model of epidemic spreading on networks where individuals have a fluctuating number of connections around a preferred degree κ. Using very simple rules for forming such preferred degree networks, we find some unusual statistical properties not found in familiar Erdös-Rényi or scale free networks. By letting κ depend on the fraction of infected individuals, we model the behavioral changes in response to how the extent of the epidemic is perceived. In our models, the behavioral adaptations can be either 'blind' or 'selective'--depending on whether a node adapts by cutting or adding links to randomly chosen partners or selectively, based on the state of the partner. For a frozen preferred network, we find that the infection threshold follows the heterogeneous mean field result λ(c)/μ = / and the phase diagram matches the predictions of the annealed adjacency matrix (AAM) approach. With 'blind' adaptations, although the epidemic threshold remains unchanged, the infection level is substantially affected, depending on the details of the adaptation. The 'selective' adaptive SIS models are most interesting. Both the threshold and the level of infection changes, controlled not only by how the adaptations are implemented but also how often the nodes cut/add links (compared to the time scales of the epidemic spreading). A simple mean field theory is presented for the selective adaptations which capture the qualitative and some of the quantitative features of the infection phase diagram.

    A rare case of progressive pseudorheumatoid dysplasia (PPD) in a 9-year-old girl is presented. Clinically, chronic painless swollen joints, accompanied by progressive motion restriction and progressive walking difficulties, were found. Radiologically, there was enlargement of the epimetaphyseal portions of the large joints, metacarpal heads, and phalanges, and generalized platyspondyly with irregular delineation of the endplates of the vertebral bodies. The radioclinical features at the peripheral joints were originally misdiagnosed as juvenile rheumatoid arthritis (JRA), and the structural spinal abnormalities were neglected and interpreted as Scheuermann's disease. However, the absence of active inflammatory parameters argues against JRA, whereas the low age of onset of the irregularities at the vertebral endplates is an argument against the diagnosis of Scheuermann's disease. The combination of the dysplastic abnormalities of the spine, with platyspondyly and Scheuermann-like lesions at an unusually low age of onset, and radiological features mimicking JRA of the peripheral joints, is the clue to the diagnosis of this rare autosomal-recessive disease. This case is the first to document the MRI features of PPD of the spine. (orig.)

    There has been very considerable progress in the past few years on the theory of two conservative, coupled, nonlinear oscillators. This is a very general theory, and applies to many equivalent systems including approximate models of particle accelerators. A typical problem of this class has a solution that is so complicated that it is impossible to find an expression for the state of the system that is valid for all time. However, recent results are making it possible to determine the next most useful type of information. This is the asymptotic behavior of individual orbits in the limit of very long times. It is just the information that is desired in many situations. For example, it determines the stability of the motion. They key to our present understanding is renormalization. The present state of the art has been described in Robert MacKay's thesis, for which this is an advertisement

    2005-01-01

    The Finkelstein-Misner metrical kinks of general relativity are homo topically nontrivial light cone configurations that can occur on space-time hypersurfaces. The number of kinks corresponds to the winding number of a timelike vector field that that is determined from the metric. This paper uses the usual Euclidean integral formula for degree of mapping as a starting point and so produces a covariant formula that can be applied to counting general relativistic kinks in any dimension. The kink number is calculated for some simple-to-visualize examples in 2 + 1 dimensions. These include hypersurfaces of differing topologies and so have relevance to mechanisms of topology change in semi-classical theories of quantum gravity

    2016-01-01

    The recent emphasis on a realist ontology that cannot be overshadowed by subjectivist or relativist perspectives seems to have a number of consequences for psychology as well. My attempt here is to analyse the relationship between happiness as a state of the individual and the states of the external world and the brain events related to (or, in some hypotheses, causally responsible for) its occurrence. It can be maintained that different degrees of realism are suitable to describe the states of happiness and this fact might have relevant psychological implications, namely for the so-called positive psychology. This is especially true now that there are methods available to induce subjective states of happiness unrelated to the external conditions usually taken to be linked to such states.

    The ATLAS Zero Degree Calorimeter (ZDC) at the Large Hadron Collider (LHC) is a set of two sampling calorimeters modules symmetrically located at 140m from the ATLAS interaction point. The ZDC covers a pseudorapidity range of |eta| > 8.3 and it is both longitudinally and transversely segmented, thus providing energy and position information of the incident particles. The ZDC is installed between the two LHC beam pipes, in a configuration such that only the neutral particles produced at the interaction region can reach this calorimeter. The ZDC uses Tungsten plates as absorber material and rods made of quartz interspersed in the absorber as active media. The energetic charged particles crossing the quartz rods produces Cherenkov light which is then detected by photomultipliers and sent to the front end electronics for processing, in a total of 120 individual electronic channels. The Tungsten plates and quartz rods are arranged in a way to segment the calorimeters in 4 longitudinal sections. The first section (...

    2017-06-01

    We propose algorithms to approximate directed information graphs. Directed information graphs are probabilistic graphical models that depict causal dependencies between stochastic processes in a network. The proposed algorithms identify optimal and near-optimal approximations in terms of Kullback-Leibler divergence. The user-chosen sparsity trades off the quality of the approximation against visual conciseness and computational tractability. One class of approximations contains graphs with speci ed in-degrees. Another class additionally requires that the graph is connected. For both classes, we propose algorithms to identify the optimal approximations and also near-optimal approximations, using a novel relaxation of submodularity. We also propose algorithms to identify the r-best approximations among these classes, enabling robust decision making.

    The investigation of submesoscale eddies and fronts is one of the leading oceanographic topics at the Ocean Sciences Meeting 2016. In order to observe these small and short-lived phenomena, planes equipped with high-resolution cameras and fast vessels were deployed during the Submesoscale Experiments (SubEx) leading to some of the first high-resolution observations of these eddies. In a future experiment, a zeppelin will be used the first time in marine sciences. The relevance of submesoscale processes for the oceans and the work of the eddy hunters is described in the fascinating 9-minute long 360 degree fulldome production Clockwork Ocean. The fully animated movie is introduced in this presentation taking the observer from the bioluminescence in the deep ocean to a view of our blue planet from space. The immersive media is used to combine fascination for a yet unknown environment with scientific education of a broad audience. Detailed background information is available at the parallax website www.clockwork-ocean.com. The Film is also available for Virtual Reality glasses and smartphones to reach a broader distribution. A unique Mobile Dome with an area of 70 m² and seats for 40 people is used for science education at events, festivals, for politicians and school classes. The spectators are also invited to participate in the experiments by presenting 360 degree footage of the measurements. The premiere of Clockwork Ocean was in July 2015 in Hamburg, Germany and will be worldwide available in English and German as of fall 2015. Clockwork Ocean is a film of the Helmholtz-Zentrum Geesthacht produced by Daniel Opitz and Ralph Heinsohn.

    McGhie-Anderson, Rose Lavine

    The purpose of this study was to gain an understanding of the social processes associated with the decision of diploma and associate degree nurses to advance academically. Advanced nursing education needs to be pursued along the continuum of the nursing career path. This education process is indispensable to the role of nurses as educator, manager, nurse leader, and researcher who will effect policy changes, assume leadership roles as revolutionary thinkers, and implement paradigmatic shifts. Data were collected from two groups of participants using face-to-face, semistructured interviews. Group 1 consisted of diploma and associate degree nurses; Group 2 consisted of baccalaureate, masters, and doctoral degree nurses who have progressed academically. Emerging from the thick, rich data were core categories of rewarding, motivating, and supporting as critical factors that influence professional advancement. This qualitative study elucidated that professional advancement was the social process that grounds. The emergent theory was the theory of professional advancement.

    Full Text Available Iron ore exploited in Brazil can be classified into several lithological types which have distinct features. The progress of mining over time leads to scarcity of high grade iron ores, leading to the exploitation of poor, contaminated and compact ores. There is a growing trend of application of process flowsheets involving grinding to promote mineral liberation, essential condition for concentration processes. Several authors have correlated metamorphism processes of banded iron formations to mineralogical features observed on itabirites from the Iron Quadrangle, mainly the crystals size. This paper presents the implications of such variation in defining the mesh of grinding. Mineralogical characterization and grinding, desliming and flotation tests have been carried out with samples from two regions of the Iron Quadrangle subjected to different degrees of metamorphism. It was found a trend of reaching satisfactory liberation degree in coarser size for the itabirite of higher metamorphic degree, which has larger crystals. The flotation tests have confirmed the mineralogical findings.

Current diagnostic criteria require the language dysfunction to remain isolated for at least two years, and to remain the salient feature as the disease progresses, usually to involve other domains such as behavior, executive functions, and judgment. Although PPA in its early stages can usually be differentiated from probable Alzheimer’s disease (PRAD and the behavioral variant of frontotemporal lobar degeneration by the absence of significant changes in memory and behavior, and the preservation of activities daily living, progression of the disease often leads to deficits more consistent with the latter. Underlying etiologies remain heterogeneous: the neuropathological characteristics associated with frontotemporal lobar degeneration, cortocobasal degeneration, and motor neuron disease are usually found. There is a strong genetic susceptibility with affliction of first-degree relatives with similar disease in up to 40 to 50% in some series. Pathogenic mutations in genes coding for the proteins tau and progranulin have been isolated. These are leading to a better understanding of the neuropathological mechanisms and hopefully targeted disease-modifying therapy. Current therapy is limited to improving mood symptoms and targeting behavior changes as they develop. Referral to specialized centers where speech therapy, counseling, and education

    A new family of exact solutions to the wave equation representing relatively undistorted progressive waves is constructed using separation of variables in the elliptic cylindrical coordinates and one of the Bateman transforms. The general form of this Bateman transform in an orthogonal curvilinear cylindrical coordinate system is discussed and a specific problem of physical feasibility of the obtained solutions, connected with their dependence on the cyclic coordinate, is addressed. The limiting case of zero eccentricity, in which the elliptic cylindrical coordinates turn into their circular cylindrical counterparts, is shown to correspond to the focused wave modes of the Bessel-Gauss type.

    Three patients with slowly progressive fluent aphasia are reported. One of the patients presented with memory disturbance. They were characterized clinically by having selective deficits in vocabulary, which resulted in impairment of confrontation naming, and auditory comprehension. MRI showed an atrophy not only in the left temporal lobe (including the superior, middle and inferior temporal gyri), hippocampus, parahippocampual gyrus, and fusiform gyrus, but also in the left parietal lobe. I-123 IMP SPECT and F-18 FDG PET were used to determine regional cerebral blood flow and regional cerebral metabolic rate, respectively. In addition to the decreased tracer uptake in the left temporal and/or parietal lobe, a decreased uptake was seen in the bilateral basal ganglia, the inner side of the temporal lobe (including the bilateral hippocampus), the right anterior temporal lobe, and the left thalamus. These findings may deny the previous thought that lesions are localized in slowly progressive fluent aphasia. Furthermore, noticeable difficulty in naming, i.e., patients unable to recognize the right answer, are considered attributable to widespread lesions from the whole left temporal lobe, including the hippocampus, to the right temporal lobe.

    Computational methods have been widely applied to toxicology across pharmaceutical, consumer product and environmental fields over the past decade. Progress in computational toxicology is now reviewed. A literature review was performed on computational models for hepatotoxicity (e.g. for drug-induced liver injury (DILI)), cardiotoxicity, renal toxicity and genotoxicity. In addition various publications have been highlighted that use machine learning methods. Several computational toxicology model datasets from past publications were used to compare Bayesian and Support Vector Machine (SVM) learning methods. The increasing amounts of data for defined toxicology endpoints have enabled machine learning models that have been increasingly used for predictions. It is shown that across many different models Bayesian and SVM perform similarly based on cross validation data. Considerable progress has been made in computational toxicology in a decade in both model development and availability of larger scale or 'big data' models. The future efforts in toxicology data generation will likely provide us with hundreds of thousands of compounds that are readily accessible for machine learning models. These models will cover relevant chemistry space for pharmaceutical, consumer product and environmental applications. Copyright © 2013 Elsevier Inc. All rights reserved.

  17. Annual progress report

    Progress has been made in calculation of cross-sections for dielectronic and radiative recombination when hot electrons are incident on partially stripped impurity ions. Calculations were completed for the cases of 1 keV and 10 keV electrons incident on ions of arbitrary Z with ionization state consistent with a 1 keV plasma temperature. It was found that dielectronic recombination dominates radiative recombination by a factor of 100 at 1 keV incident electron energy to a factor of 1000 at 10 keV incident electron energy. The work is now being extended to other plasma temperatures and is being improved by more accurate calculation of the matrix elements involved. Progress was also made in the calculation of accurate bremsstrahlung and higher order radiative processes which also occur when hot electrons are incident on partially stripped impurity ions. Formal expressions for the matrix elements have been obtained for cross-sections in a fully relativistic partial wave analysis for bremsstrahlung radiation both with and without electron excitation of the target ion. Final evaluation now awaits the evaluation of the relativistic radial integrals involved in these matrix elements. (U.S.)

  18. Ghrelin and cancer progression.

    Ghrelin is a small peptide with 28 amino acids, and has been characterized as the ligand of the growth hormone secretagogue receptor (GHSR). In addition to its original function in stimulating pituitary growth hormone release, ghrelin is multifunctional and plays a role in the regulation of energy balance, gastric acid release, appetite, insulin secretion, gastric motility and the turnover of gastric and intestinal mucosa. The discovery of ghrelin and GHSR expression beyond normal tissues suggests its role other than physiological function. Emerging evidences have revealed ghrelin's function in regulating several processes related to cancer progression, especially in metastasis and proliferation. We further show the relative GHRL and GHSR expression in pan-cancers from The Cancer Genome Atlas (TCGA), suggesting the potential pathological role of the axis in cancers. This review focuses on ghrelin's biological function in cancer progression, and reveals its clinical significance especially the impact on cancer patient outcome. Copyright © 2017 The Authors.

    Fatty liver is one of the most commonly found disease by abdominal ultrasonography. The status of fatty liver is classified into mild, moderate and severe degrees. The study was conducted to investigate the clinical significance of fatty liver using ultrasonography. Test set consisted of 2,185 patients who visited D healthcare center in Daejeon to receive an abdominal ultrasonic test from January to December 2007. Out of the 2185 patients, 524 patients was diagnosed as fatty liver (290 male and 234 female patients). They were divided into three groups, group I for mild degree. II for moderate degree, and III for severe degree, depending on the echo of liver parenchyma, the sound attenuation, and the visibility of intrahepatic blood vessels and diaphragm. Then the correlation of obesity indices, liver function tests and metabolic syndrome was analyzed for males and females separately. As for the degree of fatty liver, 350 cases (66.8%) were classified as group I, 153 cases (29.2%) as group II, and 21 cases (4.1%) as group III. In addition, severe degree of fatty liver was more frequently found in males than in females. The mean ages of three groups for males were 46.1, 44.5, and 39.1, and those for females were 48.8, 50.2, 52.4, respectively. Males with lower mean ages have severely of fatty liver for both males and females. The results in this study show that the classification into three degrees of fatty liver in ultrasonography practice is helpful to treat and observe the progress of fatty liver. In addition, careful examination is required to measure the severity of fatty liver as well as detection of it. A standardized method to classify the degree of fatty liver is also needed for more objective measurement.

    In order to preserve and to improve the quality of nuclear engineering education and training in Europe, as well to ensure the safe and economic operation of nuclear power plants, the European Nuclear Engineering Network Program (ENEN) started in 2002. It is a program aiming to establish and maintain a set of criteria for specific curricula of nuclear engineering education, in particular, for an European Master Degree in Nuclear Engineering (EMNE). The ENEN program is financed by the FP5 and has the wide support of IAEA, OECD and EU Commission departments dealing with the nuclear engineering knowledge management. The promising results up to now determined the creation of the Asian Nuclear Engineering Network (ANEN) in July 2003 and of the World Nuclear University (WNU) starting in September 2003. The paper presents the future structure of EMNE which will allow the harmonization of the curricula of the universities of Europe until the Bologna Convention will be fully accepted and operational in all European countries. The ENEN program has taken into consideration the curricula of 22 universities and research centres from 15 different European countries and proposed a feasible scheme which allows the undergraduates with a weak to strong nuclear background to continue their graduate education in the nuclear engineering field towards EMNE. As one of the contractors of this program, University 'Politehnica' of Bucharest brings its contribution and actively takes part in all activities establishing the EMNE. (author)

  8. Constraining the roughness degree of slip heterogeneity

    KAUST Repository

    Causse, Mathieu

    2010-05-07

    This article investigates different approaches for assessing the degree of roughness of the slip distribution of future earthquakes. First, we analyze a database of slip images extracted from a suite of 152 finite-source rupture models from 80 events (Mw = 4.1–8.9). This results in an empirical model defining the distribution of the slip spectrum corner wave numbers (kc) as a function of moment magnitude. To reduce the “epistemic” uncertainty, we select a single slip model per event and screen out poorly resolved models. The number of remaining models (30) is thus rather small. In addition, the robustness of the empirical model rests on a reliable estimation of kc by kinematic inversion methods. We address this issue by performing tests on synthetic data with a frequency domain inversion method. These tests reveal that due to smoothing constraints used to stabilize the inversion process, kc tends to be underestimated. We then develop an alternative approach: (1) we establish a proportionality relationship between kc and the peak ground acceleration (PGA), using a k−2 kinematic source model, and (2) we analyze the PGA distribution, which is believed to be better constrained than slip images. These two methods reveal that kc follows a lognormal distribution, with similar standard deviations for both methods.

    Modern tendencies of higher education require development of master programs providing achievement of learning outcomes corresponding to quickly variable job market needs. ITMO University represented by Applied and Computer Optics Department and Optical Design and Testing Laboratory jointly with Warsaw University of Technology represented by the Institute of Micromechanics and Photonics at The Faculty of Mechatronics have developed a novel international master double-degree program "Optical Design" accumulating the expertise of both universities including experienced teaching staff, educational technologies, and experimental resources. The program presents studies targeting research and professional activities in high-tech fields connected with optical and optoelectronics devices, optical engineering, numerical methods and computer technologies. This master program deals with the design of optical systems of various types, assemblies and layouts using computer modeling means; investigation of light distribution phenomena; image modeling and formation; development of optical methods for image analysis and optical metrology including optical testing, materials characterization, NDT and industrial control and monitoring. The goal of this program is training a graduate capable to solve a wide range of research and engineering tasks in optical design and metrology leading to modern manufacturing and innovation. Variability of the program structure provides its flexibility and adoption according to current job market demands and personal learning paths for each student. In addition considerable proportion of internship and research expands practical skills. Some special features of the "Optical Design" program which implements the best practices of both Universities, the challenges and lessons learnt during its realization are presented in the paper.

  10. Neural mechanisms mediating degrees of strategic uncertainty.

    In social interactions, strategic uncertainty arises when the outcome of one's choice depends on the choices of others. An important question is whether strategic uncertainty can be resolved by assessing subjective probabilities to the counterparts' behavior, as if playing against nature, and thus transforming the strategic interaction into a risky (individual) situation. By means of functional magnetic resonance imaging with human participants we tested the hypothesis that choices under strategic uncertainty are supported by the neural circuits mediating choices under individual risk and deliberation in social settings (i.e. strategic thinking). Participants were confronted with risky lotteries and two types of coordination games requiring different degrees of strategic thinking of the kind 'I think that you think that I think etc.' We found that the brain network mediating risk during lotteries (anterior insula, dorsomedial prefrontal cortex and parietal cortex) is also engaged in the processing of strategic uncertainty in games. In social settings, activity in this network is modulated by the level of strategic thinking that is reflected in the activity of the dorsomedial and dorsolateral prefrontal cortex. These results suggest that strategic uncertainty is resolved by the interplay between the neural circuits mediating risk and higher order beliefs (i.e. beliefs about others' beliefs). © The Author(s) (2017).

    The present invention provides a small-sized and convenient device for measuring a burnup degree of spent fuels, which can be installed without remodelling an existent fuel storage pool. Namely, a gamma-ray detecting portion incorporates a Cd-Te detector for measuring intensity ratio of gamma-rays. A neutron detecting portion incorporates a fission counter tube. The Cd-Te detector comprises a neutron shielding member for reducing radiation damages and a background controlling plate for reducing low energy gamma-rays entering from a collimator. Since the Cd-Td detector for use in a gamma-ray spectroscopy can be used at a normal temperature and can measure even a relatively strong radiation field, it can measure the intensity of gamma-rays from Cs-137 and Cs-134 in spent fuels accurately at a resolving power of less than 10 keV. Further, in a case where a cooling period is less than one year, gamma-rays from Rh-106 and Nb-95 can also be measured. (I.S.)

    A progressive batch hydrolysis process is disclosed for producing sugar from a lignocellulosic feedstock. It comprises passing a stream of dilute acid serially through a plurality of percolation hydrolysis reactors charged with feed stock, at a flow rate, temperature and pressure sufficient to substantially convert all the cellulose component of the feed stock to glucose. The cooled dilute acid stream containing glucose, after exiting the last percolation hydrolysis reactor, serially fed through a plurality of pre-hydrolysis percolation reactors, charged with said feedstock, at a flow rate, temperature and pressure sufficient to substantially convert all the hemicellulose component of said feedstock to glucose. The dilute acid stream containing glucose is cooled after it exits the last prehydrolysis reactor.

    We report a case of slowly progressive amusia and aprosody in association with orofacial and eyelid apraxias. The patient was independent in daily living activities. Insight, judgment, and behavior were intact. Her language was normal, and she demonstrated no limb, dressing, or constructional apraxia. She had no prosopagnosia, no visuospatial disturbances, and no memory impairment. Imaging studies (computed tomography, magnetic resonance imaging, single photon emission computed tomography) indicated a selective disorder of the right frontal and temporal regions. Review of the literature shows an increasing number of reports of this degenerative syndrome affecting the left dominant hemisphere and language areas, whereas cases of the syndrome affecting the right hemisphere are rare. To our knowledge, this is the first case in which aprosody and amusia were associated with a focal cortical degeneration.

    Recent progress in the study of muon colliders is presented. An international collaboration consisting of over 100 individuals is involved in calculations and experiments to demonstrate the feasibility of this new type of lepton collider. Theoretical efforts are now concentrated on low-energy colliders in the 100 to 500 GeV center-of-mass energy range. Credible machine designs are emerging for much of a hypothetical complex from proton source to the final collider. Ionization cooling has been the most difficult part of the concept, and more powerful simulation tools are now in place to develop workable schemes. A collaboration proposal for a muon cooling experiment has been presented to the Fermilab Physics Advisory Committee, and a proposal for a targetry and pion collection channel experiment at Brookhaven National Laboratory is in preparation. Initial proton bunching and space-charge compensation experiments at existing hadron facilities have occurred to demonstrate proton driver feasibility.

  1. Degree and connectivity of the Internet's scale-free topology

    2011-01-01

    This paper theoretically and empirically studies the degree and connectivity of the Internet's scale-free topology at an autonomous system (AS) level. The basic features of scale-free networks influence the normalization constant of degree distribution p(k). It develops a new mathematic model for describing the power-law relationships of Internet topology. From this model we theoretically obtain formulas to calculate the average degree, the ratios of the k min -degree (minimum degree) nodes and the k max -degree (maximum degree) nodes, and the fraction of the degrees (or links) in the hands of the richer (top best-connected) nodes. It finds that the average degree is larger for a smaller power-law exponent λ and a larger minimum or maximum degree. The ratio of the k min -degree nodes is larger for larger λ and smaller k min or k max . The ratio of the k max -degree ones is larger for smaller λ and k max or larger k min . The richer nodes hold most of the total degrees of Internet AS-level topology. In addition, it is revealed that the increased rate of the average degree or the ratio of the k min -degree nodes has power-law decay with the increase of k min . The ratio of the k max -degree nodes has a power-law decay with the increase of k max , and the fraction of the degrees in the hands of the richer 27% nodes is about 73% (the ‘73/27 rule’). Finally, empirically calculations are made, based on the empirical data extracted from the Border Gateway Protocol, of the average degree, ratio and fraction using this method and other methods, and find that this method is rigorous and effective for Internet AS-level topology.

    2004-05-05

    A two-stage 68 degrees C/55 degrees C anaerobic degradation process for treatment of cattle manure was studied. In batch experiments, an increase of the specific methane yield, ranging from 24% to 56%, was obtained when cattle manure and its fractions (fibers and liquid) were pretreated at 68 degrees C for periods of 36, 108, and 168 h, and subsequently digested at 55 degrees C. In a lab-scale experiment, the performance of a two-stage reactor system, consisting of a digester operating at 68 degrees C with a hydraulic retention time (HRT) of 3 days, connected to a 55 degrees C reactor with 12-day HRT, was compared with a conventional single-stage reactor running at 55 degrees C with 15-days HRT. When an organic loading of 3 g volatile solids (VS) per liter per day was applied, the two-stage setup had a 6% to 8% higher specific methane yield and a 9% more effective VS-removal than the conventional single-stage reactor. The 68 degrees C reactor generated 7% to 9% of the total amount of methane of the two-stage system and maintained a volatile fatty acids (VFA) concentration of 4.0 to 4.4 g acetate per liter. Population size and activity of aceticlastic methanogens, syntrophic bacteria, and hydrolytic/fermentative bacteria were significantly lower in the 68 degrees C reactor than in the 55 degrees C reactors. The density levels of methanogens utilizing H2/CO2 or formate were, however, in the same range for all reactors, although the degradation of these substrates was significantly lower in the 68 degrees C reactor than in the 55 degrees C reactors. Temporal temperature gradient electrophoresis profiles (TTGE) of the 68 degrees C reactor demonstrated a stable bacterial community along with a less divergent community of archaeal species.

    1999-01-01

    Attempts to derive the NN forces from the quark and gluon degrees of freedom have been made so far in the framework of the nonrelativistic quark-cluster model (QCM). The justification of such a model is based on the remarkable success in describing the static properties of single hadrons. In the earlier calculations, the NN s-wave phase shifts obtained with the QCM show that the model produces repulsive NN forces at short distances, which constitutes a success for the model, but fails to provide the intermediate range attraction indispensable for binding nucleons in nuclei. This drawback is amended within the context of these models, at the expense of introducing by hand intermediate-range attraction through meson-exchange potentials between quarks or/and between nucleons (quark clusters). This procedure improves the results for the phase shifts and it is often concluded that the QCM provides a good description of the short-range (SR) part of the NN potential. In our opinion, the above procedure does not provide a rigorous test of the validity of the quark-cluster model. In order to get a clear-cut conclusion one should consider the QCM in association with an accurate and well founded model for the long-medium-range (LR+MR) forces. For these reason we study a NN interaction model which satisfies this requirement. In this model, the LR+MR parts are given by the Paris NN potential and the SR part by the QCM. The quality of the model is then tested by confronting directly its predictions with data on observables rather then, as it is usually done, with phase shifts. We compute all the observables for pp and np scattering at energies below the pion production threshold for different QCM versions corresponding to different qq interactions. The results are then compared with the existing world set data. Preliminary results show that the agreement with experiment is not good. (authors)

    While tendon degeneration has been known to be an important cause of rotator cuff disease, few studies have objectively proven the association of tendon degeneration and rotator cuff disease. The purpose of this study was to investigate changes of tendon degeneration with respect to the stage of rotator cuff disease. A total of 48 patients were included in the study: 12 with tendinopathy, 12 with a partial-thickness tear (pRCT), 12 with a full-thickness tear (fRCT), and 12 as the control. A full-thickness supraspinatus tendon sample was harvested en bloc from the middle portion between the lateral edge and the musculotendinous junction of the tendon using a biopsy punch with a diameter of 3 mm. Harvested samples were evaluated using a semi-quantitative grading scale with 7 parameters after haematoxylin and eosin staining. There was no significant difference in age, gender, symptom duration, and Kellgren-Lawrence grade between the groups except for the global fatty degeneration index. All of the seven parameters were significantly different between the groups and could be categorized as follows: early responders (fibre structure and arrangement), gradual responder (rounding of the nuclei), after-tear responders (cellularity, vascularity, and stainability), and late responder (hyalinization). The total degeneration scores were not significantly different between the control (6.08 ± 1.16) and tendinopathy (6.67 ± 1.83) (n.s.). However, the score of pRCT group (10.42 ± 1.31) was greater than that of tendinopathy (P rotator cuff disease progresses from tendinopathy to pRCT, and then to fRCT. The degree of degeneration of tendinopathy was not different from that of normal but aged tendons, and significant tendon degeneration began from the stage of pRCT. The clinical relevance of the study is that strategies and goals of the treatment for rotator cuff disease should be specific to its stage, in order to prevent disease progression for tendinopathy and pRCT, as

    In September 2008 the Nursing and Midwifery Council (NMC) approved plans to change pre-registration nursing education in England to an all-graduate qualification in 2015. In 2001 the Department of Health announced a similar decision for social work qualifying education and the first graduate-only qualifying programmes began in 2003-2004. This article presents findings from a national in-depth evaluation of the social work degree in England and describes ways in which efforts have been made to improve the quality of social workers, raise the status of the profession and link practice and theory as part of the transformation to a degree level qualification. Messages for nurse educators are drawn in the light of the professions' commonalities. Copyright 2009 Elsevier Ltd. All rights reserved.

As a result, two accepted claims or theories belonging to two different sciences may not necessarily carry the same degree of truthfulness. Examining the different methodologies of deriving claims in the sciences of ʿaqīdah (Islamic Creed, fiqh (Islamic Jurisprudence and physics, the study shows that ʿaqīdah provides a holistic understanding of the universe. Physics falls short of interpreting physical phenomena unless these phenomena are looked at through the ʿaqīdah holistic view. Left to itself, error may creep into laws of physics due to the methodology of conducting the physical experiments, misinterpreting the experimental results, or accepting invalid assumptions. As for fiqh, it is found that apart from apparent errors, fiqh views cannot be falsified. It is, therefore, useful to consider ʿaqīdah as a master science which would permit all other sciences to live in harmony.

  7. Dynamically prioritized progressive transmission

    1992-04-01

    Retrieval of image data from a centralized database may be subject to bandwidth limitations, whether due to a low-bandwidth communications link or to contention from simultaneous accesses over a high-bandwidth link. Progressive transmission can alleviate this problem by encoding image data so that any prefix of the data stream approximates the complete image at a coarse level of resolution. The longer the prefix, the finer the resolution. In many cases, as little at 1 percent of the image data may be sufficient to decide whether to discard the image, to permit the retrieval to continue, or to restrict retrieval to a subsection of the image. Our approach treats resolution not as a fixed attribute of the image, but rather as a resource which may be allocated to portions of the image at the direction of a user-specified priority function. The default priority function minimizes error by allocating more resolution to regions of high variance. The user may also point to regions of interest requesting priority transmission. More advanced target recognition strategies may be incorporated at the user's discretion. Multispectral imagery is supported. The user engineering implications are profounded. There is immediate response to a query that might otherwise take minutes to complete. The data is transmitted in small increments so that no single user dominates the communications bandwidth. The user-directed improvement means that bandwidth is focused on interesting information. The user may continue working with the first coarse approximations while further image data is still arriving. The algorithm has been implemented in C on Sun, Silicon Graphics, and NeXT workstations, and in Lisp on a Symbolics. Transmission speeds reach as high as 60,000 baud using a Sparc or 68040 processor when storing data to memory; somewhat less if also updating a graphical display. The memory requirements are roughly five bytes per image pixel. Both computational and memory costs may be reduced

    We can summarize the IPY goals as: (a) make major advances in polar knowledge and understanding; (b) leave a legacy of new or enhanced observational systems, facilities and infrastructure; (c) excite a new generation of polar scientists and engineers, and (d) elicit exceptional interest and participation from polar residents, schoolchildren, the general public, and decision-makers, worldwide. This talk reports on the progress and prospects in each of those areas from an overall international view; separate talks will describe details of future researcher and the IPY outreach efforts. To achieve major advances in knowledge, IPY has entrained the intellectual resources of thousands of scientists, many more than expected, often from 'non- polar' nations, and representing an unprecedented breadth of scientific specialties; integration of those efforts across disciplines to achieve integrated system-level understanding remains a substantial challenge. Many national and international organizations prepare plans to sustain new and improved observational systems, but clear outcomes and the necessary resources remain elusive. International outreach networks gradually build breadth and strength, largely through IPY Polar Science Days and other internationally- coordinated IPY events. A new Association of Polar Early Career Scientists (APECS) devotes talent and energy to shaping the future of polar research. These activities and networks may, with time and with continued international coordination, achieve an exceptional level of interest and participation. In all areas, much work remains.

  15. CERN: LHC progress

    The push for CERN's next major project, the LHC proton collider to be built in the 27-kilometre LEP tunnel, is advancing on a wide front. For the machine itself, there has been considerable progress in the detailed design. While the main thrust is for proton-proton collisions, heavy ions are also on the LHC collision menu. On the experimental side, proposals are coming into sharper focus. For the machine, the main aim is for the highest possible proton collision energies and collision rates in the confines of the existing LEP tunnel, and the original base design looked to achieve these goals in three collision regions. Early discussions on the experimental programme quickly established that the most probable configuration would have two collision regions rather than three. This, combined with hints that the electronics of several detectors would have to handle several bunch crossings at a time, raised the question whether the originally specified bunch spacing of 15 ns was still optimal

    As society's appetite for information continues to grow, so does our need to process this information with increasing speed and versatility. Many believe that the one-size-fits-all solution of digital electronics is becoming a limiting factor in certain areas such as data links, cognitive radio, and ultrafast control. Analog photonic devices have found relatively simple signal processing niches where electronics can no longer provide sufficient speed and reconfigurability. Recently, the landscape for commercially manufacturable photonic chips has been changing rapidly and now promises to achieve economies of scale previously enjoyed solely by microelectronics. By bridging the mathematical prowess of artificial neural networks to the underlying physics of optoelectronic devices, neuromorphic photonics could breach new domains of information processing demanding significant complexity, low cost, and unmatched speed. In this article, we review the progress in neuromorphic photonics, focusing on photonic integrated devices. The challenges and design rules for optoelectronic instantiation of artificial neurons are presented. The proposed photonic architecture revolves around the processing network node composed of two parts: a nonlinear element and a network interface. We then survey excitable lasers in the recent literature as candidates for the nonlinear node and microring-resonator weight banks as the network interface. Finally, we compare metrics between neuromorphic electronics and neuromorphic photonics and discuss potential applications.

    Objective: To define the clinical spectrum and etiology of progressive myoclonic epilepsies (PMEs) in Italy using a database developed by the Genetics Commission of the Italian League against Epilepsy. Methods: We collected clinical and laboratory data from patients referred to 25 Italian epilepsy centers regardless of whether a positive causative factor was identified. PMEs of undetermined origins were grouped using 2-step cluster analysis. Results: We collected clinical data from 204 patients, including 77 with a diagnosis of Unverricht-Lundborg disease and 37 with a diagnosis of Lafora body disease; 31 patients had PMEs due to rarer genetic causes, mainly neuronal ceroid lipofuscinoses. Two more patients had celiac disease. Despite extensive investigation, we found no definitive etiology for 57 patients. Cluster analysis indicated that these patients could be grouped into 2 clusters defined by age at disease onset, age at myoclonus onset, previous psychomotor delay, seizure characteristics, photosensitivity, associated signs other than those included in the cardinal definition of PME, and pathologic MRI findings. Conclusions: Information concerning the distribution of different genetic causes of PMEs may provide a framework for an updated diagnostic workup. Phenotypes of the patients with PME of undetermined cause varied widely. The presence of separate clusters suggests that novel forms of PME are yet to be clinically and genetically characterized.

  19. Resistance to technological progress

    This article deals with the tolerance test the constitutional system (Basic Law) of the Federal Republic of Germany is currently put to as a consequence of the resistance to the power structure of this country, which is expressed in the name of protection and defense for the environment and world peace. This biopacifistic resistance movment, the author says, has nothing to do with the legal right to resist, as laid down in art. 20 (4) of the Basic Law. According to the author, this attitude is an offspring of fear of the hazards of technological progress, primarily of nuclear hazards. Practical resistance, the author states, is preceded by theoretical resistance in speech: De-legitimation of the democratic legality, of the parliamentary functions, of the supreme power of the government, and denial of the citizens duty of obedience. The author raises the question as to whether this attitude of disobedience on ecological grounds marks the onset of a fourth stage of development of the modern state, after we have passed through stages characterised by fear of civil war, of tyranny, and of social privation and suffering. There are no new ideas brought forward by the ecologically minded movement, the author says, for re-shaping our institutions or constitutional system. (HP) [de

    Amyotrophic lateral sclerosis (ALS) presents with varying degrees of brain degeneration that can extend beyond the corticospinal tract (CST). Furthermore, the clinical course and progression of ALS varies widely. Brain degeneration detected using structural MRI could reflect disease progression. On study registration, 3-Tesla volumetric MRI and diffusion tensor imaging scans were obtained at baseline in 38 healthy controls and 67 patients with sporadic ALS. Patients had Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) scores of ≥36 and did not have the chromosome 9, open reading frame 72 repeat expansion. Six months later, changes in ALSFRS-R (ΔALSFRS-R) scores were calculated and patients were grouped into three categories, namely, patients with slow progression with ΔALSFRS-R scores ≤3 (n=19), intermediate progression with ΔALSFRS-R scores =4, 5 and 6 (n=36) and rapid progression with ΔALSFRS-R scores ≥7 (n=12). We analysed voxel-based morphometry and tract-based spatial statistics among these subgroups and controls. In comparison with controls, patients with ALS showed grey matter atrophy and decreased fractional anisotropy beyond the motor cortex and CST, especially in the frontotemporal lobes and basal ganglia. Moreover, the degree of change was highly proportional to ΔALSFRS-R at the 6-month assessment. A more rapid disease progression and poorer functional decline were associated with greater involvement of the extra-motor cortex and basal ganglia, suggesting that the spatial extent of brain involvement can be an indicator of the progression in ALS. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  10. The Thermochronologist's Progress

    Zeitler, P. K.

    2011-12-01

    We owe our current understanding of thermochronology less to a series of revolutionary insights than to a somewhat uneven intellectual pilgrimage that over fifty years has progressed in fits and starts. Though hampered at times by overenthusiasm, oversimplification, and misunderstandings, on balance the field advanced thanks to a blend of curiosity-driven research, tool-building motivated by new ideas about Earth science, and improvements in technology. But now that we've exploited most radiogenic systems and the major minerals that host them, and now that our models can devour CPU time along with the best of them, are we done? Have we reached peak thermochron? The answer of course is no, and papers in this session will demonstrate what new technologies and techniques might have to offer in the coming years. However, I will argue that the discipline as a whole has matured to a point where if thermochronology is to remain a mainstream tool as opposed to a weekend sport, we need to get serious about several challenges. The most fundamental challenge is that current geodynamic models (and even more complex models we can envision coding) have outpaced our meagre stockpile of kinetic calibrations, our understanding of detailed isotope systematics, and our ability to generate data with sufficient throughput. These issues will not be addressed adequately through the business-as-usual approach that brought us to our current knowledge, and some community effort will probably be needed to coordinate the hard work that will be required. But any serious attempt to answer important questions with accurate thermal histories that have low and well-defined uncertainties will require that we actually know the kinetics for the specific samples we are analyzing, that we fully understand scatter in the data, that we work with the large sample numbers that are required for some problems like landscape evolution, and that inversion tools fully explore the important aspects of both the

    Medulloblastoma is the most common central nervous system tumour in children aged 0–4 years, with 75% of cases occurring in patients <16 years, and rare in adults. The intent of this audit is to review a single centre's experience and to compare outcomes with other centres' outcomes. This Ethics approved retrospective audit evaluates the paediatric population aged <16 years who received radiotherapy as their initial or salvage treatment at the Prince of Wales Hospital Cancer Centre between 1972 and 2007. The primary and secondary end-points were progression-free survival (PFS) and cancer-specific survival (CSS), with comparisons made between patients treated before and after 1990, and the impact of high- and low-risk disease. There were 80 eligible patients, 78 who had radiotherapy at initial presentation, and 2 at the time of recurrence. Median age was 6.5 years, 52 were boys and 28 were girls. Seventy-eight patients had a surgical procedure and ultimately received craniospinal radiotherapy. Of these 78 patients, 32 (40%) had a macroscopically complete resection. The 5-year PFS was 69.7%. The 5-year PFS for patients treated pre and post 1990 was 66.1% and 71.8%, respectively. The 5-year CSS for high- and low-risk patients was 61.1% and 78.4%, respectively. Ultimately, 33% of patients were dead due to disease. This audit demonstrates those children referred to this facility for treatment have comparable survival to that of other major centres.

    Fusion research is undertaken all over the world with the objective of realising an environmentally responsible source of energy with essentially unlimited and widely distributed fuel reserves. The results of the worldwide efforts made in recent years are now embodied in ITER, the International Thermonuclear Experimental Reactor, designed to produce at least 500 MW of fusion power with a power gain of ten. ITER will test for the first time the interaction of fusion plasma physics with power station technology. In this international framework, during 2004 Fusion Technical and Scientific Unit of ENEA obtained important results in several keys areas. At the Frascati Tokamak Upgrade the lower hybrid microwave system was fully exploited to study the generation and control of the plasma current, and the electron cyclotron heating system reached full power (1.5 MW). With the simultaneous injection of the two waves, good energy confinement regimes with internal transport barriers were obtained at the highest plasma densities ever achieved. Advanced scenario regimes were also addressed in the activities of ENEA at JET. The engineering design of the IGNITOR machine was finalised, and significant progress was made in understanding the plasma physics regimes. Among the technology activities, the qualification of the deposition process of a copper liner on carbon fibre composite (CFC) hollow tiles may be mentioned as the most important achievement. This innovative pre brazed casting process is a competitive candidate for the fabrication of the CFCbased ITER divertor components. ENEA participated in the European activity for the definition and production on an industrial scale of an advanced Nb3Sn strand for the ITER superconducting central solenoid and toroidal field coils. Contributions were also made to the design of the final conductor layout and the characterisation tests. Inertial fusion studies continued along the previous lines, namely, the study of the implosion

    Fusion research is undertaken all over the world with the objective of realising an environmentally responsible source of energy with essentially unlimited and widely distributed fuel reserves. The results of the worldwide efforts made in recent years are now embodied in ITER, the International Thermonuclear Experimental Reactor, designed to produce at least 500 MW of fusion power with a power gain of ten. ITER will test for the first time the interaction of fusion plasma physics with power station technology. In this international framework, during 2004 Fusion Technical and Scientific Unit of ENEA obtained important results in several keys areas. At the Frascati Tokamak Upgrade the lower hybrid microwave system was fully exploited to study the generation and control of the plasma current, and the electron cyclotron heating system reached full power (1.5 MW). With the simultaneous injection of the two waves, good energy confinement regimes with internal transport barriers were obtained at the highest plasma densities ever achieved. Advanced scenario regimes were also addressed in the activities of ENEA at JET. The engineering design of the IGNITOR machine was finalised, and significant progress was made in understanding the plasma physics regimes. Among the technology activities, the qualification of the deposition process of a copper liner on carbon fibre composite (CFC) hollow tiles may be mentioned as the most important achievement. This innovative pre brazed casting process is a competitive candidate for the fabrication of the CFCbased ITER divertor components. ENEA participated in the European activity for the definition and production on an industrial scale of an advanced Nb3Sn strand for the ITER superconducting central solenoid and toroidal field coils. Contributions were also made to the design of the final conductor layout and the characterisation tests. Inertial fusion studies continued along the previous lines, namely, the study of the implosion

    LIFE-II inertial confinement fusion power plant design study uses a liquid fall, in the form of jets to protect the first structural wall from neutron damage, x rays, and blast to provide a 30-y lifetime. This is a progress report of an incomplete and ongoing study. HYLIFE-I used liquid lithium. HYLIFE-11 avoids the fire hazard of lithium by using a molten salt composed of fluorine, lithium, and beryllium (Li 2 Be 4 ) called Flibe. Access for heavy-ion beams is provided. Calculations for assumed heavy-ion beam performance show a nominal gain of 70 at 5 MJ producing 350 MJ, about 5.2 times less yield than the 1.8 GJ from a driver energy of 4.5 MJ with gain of 400 for HYLIFE-I. The nominal 1 GWe of power can be maintained by increasing the repetition rate by a factor of about 5.2, from 1.5 to 8 Hz. A higher repetition rate requires faster re-establishment of the jets after a shot, which can be accomplished in part by decreasing the jet fall height and increasing the jet flow velocity. Multiple chambers may be required.In addition, although not considered for HYLIFE-I there is undoubtedly liquid splash that must be forcibly cleared because gravity is too slow, especially at high repetition rates. Splash removal can be accomplished by either pulsed or oscillating jet flows. The cost of electricity is estimated to be 0.10 $/kW· in constant 1990 dollars, about twice that of future coal and light water reactor nuclear power. The driver beam cost is about one-half the total cost

    Clean Air Hamilton is the new name of the Hamilton-Wentworth Air Quality Initiative and its implementation committee, which began in 1995 as a collaborative, multi-sectoral effort to identify and examine important air quality issues and to implement strategies to reduce many of the harmful emissions that endanger human health. During the year 2000 Clean Air Hamilton focused on nine program areas. Strategies were initiated to (1) reduce single occupancy auto trips, (2) purchase low emission vehicles, (3) model transportation emissions, (4) reduce smog-causing emissions, (5) plant trees, (6) provide advice on air quality related land use and transportation issues for consideration in city-wide planning, (7) promote public awareness through social marketing, (8) study fugitive road dust, and (9) reduce transboundary air pollution. A number of indicators to measure progress in efforts to improve air quality have been developed; many of these indicators show significant improvements which, taken collectively, show a positive trend toward cleaner air. The report highlights major accomplishment of Clean Air Hamilton; reports trends in ambient air quality data; assesses human health impacts of air quality, and recommends strategies for further improvements. Among major improvements, inhalable particulate (PM10) levels have decreased by about 20 per cent since 1991; sulphur dioxide levels dropped by 40 per cent since 1989 at industrial sampling sites and 20 per cent at the downtown sampling site; the air pollution index has remained under the advisory level of 32 at all API stations in Hamilton since June 1996. Benzene levels in air decreased by over 50 per cent near the Dofasco plant compared to the five-year composite average from 1994-1998. Given these accomplishments, participants in Clean Air Hamilton believe that while there is much room for improvement, the efforts to date have been worthwhile and provide encouragement for the future. 14 figs., 4 appendices

    The Institute of Medicine (IOM) Future of Nursing report, identified eight recommendations for nursing to improve health care for all Americans. The Texas Team for Advancing Health Through Nursing embraced the challenge of implementing the recommendations through two diverse projects. One group conducted a broad, online survey of leadership, practice, and academia, focusing on the IOM recommendations. The other focused specifically on academic progression through the use of CABNET (Consortium for Advancing Baccalaureate Nursing Education in Texas) articulation agreements. The survey revealed a lack of knowledge and understanding of the IOM recommendations, prompting development of an online IOM toolkit. The articulation agreements provide a clear pathway for students to the RN-to-BSN degree students. The toolkit and articulation agreements provide rich resources for implementation of the IOM recommendations.

    The authors studied gastric emptying (GE) in patients with peripheral manifestations of progressive systemic sclerosis (PSS) using a radionuclide method. 18 patients underwent esophageal manometry and a GE study using chicken liver labeled in vivo with Tc-99m sulfur colloid as a marker of solid emptying. GE was also measured in 13 normal volunteers. 4 PSS patients with normal esophageal motility also had normal GE. The GE of 14 PSS patients with abnormal esophageal motility was significantly (p < 0.05) delayed; with 67.4% retention of isotope after 2 hours compared to 49.8 in normals. The authors conclude that GE of solids is slow in approximately 2/3 of PSS patients with abnormal esophageal motility but is normal if the esophagus is uninvolved; Delayed GE may contribute to the severity of gastroesophageal reflux in PSS patients and the degree of dysphasgia; and Metoclopramide accelerates GE in PSS patients and should have a valuable therapeutic role

    Many real-world networks exhibit correlations between the node degrees. For instance, in social networks nodes tend to connect to nodes of similar degree and conversely, in biological and technological networks, high-degree nodes tend to be linked with low-degree nodes. Degree correlations also affect the dynamics of processes supported by a network structure, such as the spread of opinions or epidemics. The proper modelling of these systems, i.e., without uncontrolled biases, requires the sampling of networks with a specified set of constraints. We present a solution to the sampling problem when the constraints imposed are the degree correlations. In particular, we develop an exact method to construct and sample graphs with a specified joint-degree matrix, which is a matrix providing the number of edges between all the sets of nodes of a given degree, for all degrees, thus completely specifying all pairwise degree correlations, and additionally, the degree sequence itself. Our algorithm always produces independent samples without backtracking. The complexity of the graph construction algorithm is {O}({NM}) where N is the number of nodes and M is the number of edges.

    The Doctor of Philosophy is the highest academic degree that can be obtained in universities. Graduate Education Program in Medicine in Mexico is divided into 2 major categories: Medical Specialty and Master studies/Doctor of Philosophy. The objective of this study was to demonstrate the importance of master's degrees and Doctor of Philosophy in general surgery. A literature search in PubMed and Medline among others, from 1970 to 2015 with subsequent analysis of the literature reviews found. The physicians who conducted doctoral studies stand out as leaders in research, teaching and academic activities. Dual training with a doctorate medical specialty is a significant predictor for active participation in research projects within the best educational institutions. It is important to study a PhD in the education of doctors specialising in surgery, who show more training in teaching, research and development of academic activities. Currently, although there is a little proportion of students who do not finish the doctoral program, the ones who do are expected to play an important role in the future of medical scientific staff. It has been shown that most doctors with Doctor of Philosophy have wide range of career options. The importance of doctoral studies in the formation of general surgery is due to various reasons; the main one being comprehensively training physician scientists who can develop in clinical, teaching and research.

    Within the coming decade, the demand for well-trained pharmacists is expected to only increase, especially with the aging of the United States (US) population. To help fill this growing demand, the University of California, Irvine (UCI) aims to offer a unique pre-pharmacy degree program and has developed a Bachelor of Science (BS) degree in Pharmaceutical Sciences to help achieve this goal. In this commentary, we share our experience with our curriculum and highlight its features in an effort to encourage other institutions to enhance the learning experience of their pre-pharmacy students. The efforts of the UCI Department of Pharmaceutical Sciences has resulted in UCI being consistently ranked as one of the top feeder institutions by the Pharmacy College Application Service (PharmCAS) in recent years. The UCI Pharmaceutical Sciences Bachelor of Science offers a unique pre-pharmacy educational experience in an effort to better prepare undergraduates for the rigors of the doctorate of pharmacy curriculum.

    We use OECD members' data to ascertain that new-born technological inventions increase the degree of inequality but that this declines as the technology disperses into the overall economy (e.g., Galor and Tsiddon, 1997; Weil, 2005). Therefore, we show explicitly that Kuznets curve does not converge to a single inverted U-curve but fluctuates through technological progress as a sine curve.

    In CJD the current work continued concerning EXFOR compilation and fulfillment of NRDC-2000 Recommendations and Actions. Much efforts were applied for restoring CJD Web page. Evaluation works were also in process. Compilation into EXFOR continues on steadily. Since March 2000 up to April 2001 four TRANS tapes containing 69 Entries were prepared and sent to other centers. 25 new EXFOR Entries were compiled. An analysis and an evaluation are made for the threshold reactions cross sections leading to production of the long-lived radioactive nuclides on the irradiation of steel by thermonuclear neutron spectrum. Fifty excitation functions were evaluated. Many of them are considerably different from available evaluations of other libraries. During two years, together with JAERI, comparative analysis was performed of (n,2n) and (n,3n) reactions for 150 fission products from available evaluated data libraries. The result of analysis will be published this year. The joint work on consistent evaluation of some (n,2n) and (n,np) excitation functions for even-even isotopes was made on the basis of empirical systematics. The work was completed on evaluation of the spectra and production cross sections of gamma-rays in inelastic interactions of 14-Mev neutrons with the number of nuclei: Li-6, Li-7, Al, Ti, Cr, Fe, Cu, Pb, Bi, U-235. CJD continues the work on evaluation of neutron data for minor actinides. This year Am-242m will be evaluated, and Np-237, Am-241, Am-243, Cm-243, Cm-244 will be tested and improved. Full file of Bi was prepared. Full files for Pb isotopes are in process of preparation. There exist a plan to analyze full files for isotopes of Cr, Fe, Ni from existing evaluated data libraries, to select more reliable cross sections, and to create improved files for these isotopes. Together with the Theoretical Department the work is in progress on the determination of uncertainties of existing evaluated data and development of covariance matrices for some important

  10. Resonant x-ray scattering in manganites: study of the orbital degree of freedom

    2002-01-01

    The orbital degree of freedom of electrons and its interplay with spin, charge and lattice degrees of freedom are some of the central issues in colossal magnetoresistive manganites. The orbital degree of freedom has until recently remained hidden, since it does not couple directly to most experimental probes. Development of synchrotron light sources has changed the situation; by the resonant x-ray scattering (RXS) technique the orbital ordering has successfully been observed. In this article, we review progress in the recent studies of RXS in manganites. We start with a detailed review of the RXS experiments applied to the orbital-ordered manganites and other correlated electron systems. We derive the scattering cross section of RXS, where the tensor character of the atomic scattering factor (ASF) with respect to the x-ray polarization is stressed. Microscopic mechanisms of the anisotropic tensor character of the ASF are introduced and numerical results of the ASF and the scattering intensity are presented. The azimuthal angle scan is a unique experimental method to identify RXS from the orbital degree of freedom. A theory of the azimuthal angle and polarization dependence of the RXS intensity is presented. The theoretical results show good agreement with the experiments in manganites. Apart from the microscopic description of the ASF, a theoretical framework of RXS to relate directly to the 3d orbital is presented. The scattering cross section is represented by the correlation function of the pseudo-spin operator for the orbital degree of freedom. A theory is extended to the resonant inelastic x-ray scattering and methods to observe excitations of the orbital degree of freedom are proposed. (author)

    The main goal of this work has been to study the effect of the textural properties of coal chars, obtained from partially burned coal, on their reactivity to oxygen. A low volatile bituminous coal was used to prepare chars, with different levels of burn-off, in a bench-scale fluidised bed reactor. Textural characterisation of the samples was accomplished by measuring true (helium) and apparent (mercury) densities, and mercury porosimetry. An increase in the burn-off degree gave rise to a densification of the chars. Porosity development greatly changed during progressive burning of the samples. DTG burning profiles and isothermal gasification were utilised to estimate the reactivities of the precursor coal and its partially burned chars. Reactivity reached a maximum value at an intermediate burn-off and strongly decreased at higher burn-off degrees. (orig.)

    Full Text Available As a unique and versatile undergraduate degree program, a Bachelor of Science in Pharmaceutical Sciences (BSPS is offered by a number of colleges/schools of pharmacy. These provide a bachelor's degree concentrated in pharmaceutical sciences, and can be a non-Doctor of Pharmacy option, possibly before progressing to graduate degree studies. Recently implemented at the University of Toledo College of Pharmacy and Pharmaceutical Sciences (UTCPPS, one such BSPS major is Cosmetic Science and Formulation Design. This new undergraduate major was created to serve the needs of the cosmetic and personal care industry, with a great need identified for well-trained new professionals with basic knowledge in the sciences and business. This Cosmetic Science and Formulation Design major was added to four other BSPS majors at UTCPPS. Introduced in 2013, this major is the only functioning undergraduate degree in Cosmetic Science and Formulation Design in the United States. Preliminary job placement data provides promising evidence that this undergraduate major has helped graduates launch a career in the cosmetic and personal care, or pharmaceutical industries. Based on our experience from the past three years, we believe that this cosmetic science major has been worth its resource investment. We hope others designing new undergraduate pharmaceutical sciences programs might integrate advice from this experience into their impending programs.   Type: Idea Paper

    Measurements of the fracture toughness of the production-scale heat (832665) of V-4Cr-4Ti have been performed at 25{degrees}C and {minus}196{degrees}C using compact tension (CT) specimens. Test specimens were vacuum annealed at either 1000{degrees}C for 1 hour (HT1) or 1050{degrees}C for two hours (HT2). Specimens given the HT1 treatment were annealed after final machining, whereas the HT2 specimens received the 1050{degrees}C anneal at Teledyne Wah Chang prior to final machining. Following machining HT2 specimens were then vacuum annealed at 180{degrees}C for two hours to remove hydrogen. Specimens treated using HT1 had a partially recrystallized microstructure and those treated using HT2 had a fully recrystallized microstructure. The fracture toughness at 25{degrees}C was determined by J-integral tests and at {minus}196{degrees}C by ASTM E 399 type tests. Toughness values obtained at {minus}196{degrees}C were converted to J-integral values for comparison to the 25{degrees}C data. The 25{degrees}C fracture toughness was very high with none of the specimens giving valid results per ASTM criteria. Specimens fractured by microvoid coalescence. The fracture toughness at {minus}196{degrees}C was much lower than that at 25{degrees}C and the fracture surface showed predominantly cleavage features. The present results show a transition from ductile to brittle behavior with decreasing test temperature which is not observed from one-third scale Charpy impact tests. The fracture toughness at {minus}196{degrees}C was still quite high, however, at about 75 kJ/m{sup 2}. Delaminations in planes normal to the thickness direction were seen at both test temperatures. Fracture surfaces inside the delaminations exhibited nearly 100% cleavage facets. The cause of the brittle delaminations was not determined, but will be a subject for further investigation.

    Although it is not yet visible, much progress has been made on the Astronomy Genealogy Project (AstroGen) since it was accepted as a project of the Historical Astronomy Division (HAD) three years ago. AstroGen will list the world's astronomers with information about their highest degrees and advisors. (In academic genealogy, your thesis advisor is your parent.) A small group (the AstroGen Team) has compiled a database of approximately 12,000 individuals who have earned doctorates with theses (dissertations) on topics in astronomy, astrophysics, cosmology, or planetary science. These include nearly all those submitted in Australia, Canada, the Netherlands, and New Zealand, and most of those in the United States (all through 2014 for most universities and all through 1990 for all). We are compiling more information than is maintained by the Mathematics Genealogy Project (MGP). In addition to name, degree, university, year of degree, and thesis advisor(s), all provided by MGP as well, we are including years of birth and death when available, mentors in addition to advisors, and links to the thesis when it is online and to the person's web page or obituary, when we can find it. We are still struggling with some questions, such as the boundaries of inclusion and whether or not to include subfields of astronomy. We believe that AstroGen will be a valuable resource for historians of science as well as a source of entertainment for those who like to look up their academic family trees. A dedicated researcher following links from AstroGen will be able to learn quite a lot about the careers of astronomy graduates of a particular university, country, or era. We are still seeking volunteers to enter the graduates of one or more universities.

    This report documents the activities within the CBM project in 2007. Significant progress has been made in the optimization of the simulation software, the layout and development of detectors, the design of front-end electronics, and the concepts for data acquisition. The simulation and analysis routines have been completely integrated into the software framework (FAIRoot and CBMroot), and can be used now easily by users outside GSI. A breakthrough has been achieved in the development of fast algorithms for track and vertex reconstruction which have been improved in speed by a factor of 10{sup 5}. These fast routines permit to perform high-statistics simulations for detailed detector layout optimization. Full event reconstruction based on realistic detector properties and particle multiplicities as given by microscopic transport models are routinely used in the feasibility studies. A version of the Silicon Tracking System is now implemented in the simulation software comprising 8 detector layers based on microstrip technology only, including the readout cables, and the mechanical detector structure. The studies of open charm detection have been extended to D{sub s}{sup +} and {lambda}{sub c}, taking into account a realistic layout of the Silicon Pixel Microvertex detector. The identification of electrons has been optimized by improved ring recognition algorithms and transition radiation simulations. The Ring Imaging Cherenkov (RICH) detector has been redesigned, resulting in a reduction by a factor of two in mirror size and number of readout channels without reducing the pion rejection capability. The muon detection system has been optimized with respect to the number of detector layers. The muon simulations take into account detector inefficiencies and a segmentation of the muon chambers into pads according to a nominal occupancy of 5% for central Au+Au collisions. Studies for a dimuon trigger show promising results. Radiation dose simulations using the FLUKA

These fast routines permit to perform high-statistics simulations for detailed detector layout optimization. Full event reconstruction based on realistic detector properties and particle multiplicities as given by microscopic transport models are routinely used in the feasibility studies. A version of the Silicon Tracking System is now implemented in the simulation software comprising 8 detector layers based on microstrip technology only, including the readout cables, and the mechanical detector structure. The studies of open charm detection have been extended to D s + and Λ c , taking into account a realistic layout of the Silicon Pixel Microvertex detector. The identification of electrons has been optimized by improved ring recognition algorithms and transition radiation simulations. The Ring Imaging Cherenkov (RICH) detector has been redesigned, resulting in a reduction by a factor of two in mirror size and number of readout channels without reducing the pion rejection capability. The muon detection system has been optimized with respect to the number of detector layers. The muon simulations take into account detector inefficiencies and a segmentation of the muon chambers into pads according to a nominal occupancy of 5% for central Au+Au collisions. Studies for a dimuon trigger show promising results. Radiation dose simulations using the FLUKA transport code have been

  17. Characteristics of regents college nontraditional nuclear technology degrees

    DeSain, G.W.

    1989-01-01

    In 1971, the Board of Regents of The University of The State of New York created Regents College Degrees to assess academic knowledge of working adults and award college degrees based on demonstrated knowledge rather than time spent in a college classroom. It was founded on a basic premise that seemed radical to some but which is now widely accepted: What a person knows is more important than how or where that knowledge was acquired. Regents College degrees, therefore, are a different concept of a college: one that is an assessing institution rather than a teaching institution. It has no campus and offers no courses. Students can combine college credits from a variety of different sources int an accredited degree program. Staff and faculty evaluate that credit according to the requirements of the particular degree program. When all requirements are met, the Board or Regents of The University of The State of New York confers the degree

  18. Does a bachelor’s degree pay off?

    DEFF Research Database (Denmark)

    Neugebauer, Martin; Weiss, Felix

    Academic education is generally rewarded by employers, but what happens to graduates if they are trained for two years less and have to compete with vocationally trained labor market entrants in a similar field of study? Focusing on Germany, we analyze labor market entries of individuals eligible...... for higher education, who either opted for newly introduced short bachelor’s degrees, or for well-established vocational degrees. Based on Microcensus data, we find that bachelor’s degrees from classical universities are associated with higher earnings and more prestigious jobs than initial vocational...... training degrees, and with higher prestige (but similar earnings) than further vocational degrees. However, bachelor’s degrees from universities are also related to higher risks of unemployment or fixed-term employment. Universities of applied sciences, which combine academic and practical training, offer...

    M. S. Omelkova

    2013-01-01

    Full Text Available In this paper we consider some families of smooth rational curves of degree 2, 3 and 4 on a smooth Fano threefold X which is a linear section of the Grassmanian G(1, 4 under the Pl¨ucker embedding. We prove that these families are irreducible. The proof of the irreducibility of the families of curves of degree d is based on the study of degeneration of a rational curve of degree d into a curve which decomposes into an irreducible rational curve of degree d−1 and a projective line intersecting transversally at a point. We prove that the Hilbert scheme of curves of degree d on X is smooth at the point corresponding to such a reducible curve. Then calculations in the framework of deformation theory show that such a curve varies into a smooth rational curve of degree d. Thus, the set of reducible curves of degree d of the above type lies in the closure of a unique component of the Hilbert scheme of smooth rational curves of degree d on X. From this fact and the irreducibility of the Hilbert scheme of smooth rational curves of degree d on the Grassmannian G(1, 4 one deduces the irreducibility of the Hilbert scheme of smooth rational curves of degree d on a general Fano threefold X.

    2009-05-01

    Exploring the inception and growth of associate degree nursing education informs our understanding of what led to such explosive growth so that most of the nursing workforce is currently educated at the associate degree level. The success of associate degree nursing programs led to many divisive years in nursing education of differentiation of practice debates that were hardly productive. Work world practices and patient needs are creating pressures on community colleges to join forces with universities to increase the percentage of baccalaureate-educated nurses. Associate degree nursing education continues to evolve to meet the demands of a higher educated nursing workforce.

    Emphysema is one of the most widespread diseases in subjects with smoking history. The gold standard method for estimating the severity of emphysema is a lung function test, such as forced expiratory volume in first second (FEV1). However, several clinical studies showed that chest CT scans offer...... more sensitive estimates of emphysema progression. The standard CT densitometric score of emphysema is the relative area of voxels below a threshold (RA). The RA score is a global measurement and reflects the overall emphysema progression. In this work, we propose a framework for estimation of local...... emphysema progression from longitudinal chest CT scans. First, images are registered to a common system of coordinates and then local image dissimilarities are computed in corresponding anatomical locations. Finally, the obtained dissimilarity representation is converted into a single emphysema progression...

    2013-07-01

    The doctor of philosophy (PhD) degree in nursing science prepares nurses to be scientists through a rigorous program of scholarship and research. Nurses who complete this degree are recognized globally as researchers who are expected to pursue a career of intellectual inquiry. Today, the internationally small cohort of PhD-prepared nurses contributes empirically to the generation and development of nursing science. There is currently a shortage of doctorally prepared nurses to meet the increased demands for researchers and educators in schools of nursing and experts in patient care. The Institute of Medicine has recommended doubling the number of doctorally prepared nurses by 2020 and has emphasized that nurses achieve higher levels of education and training through an improved educational system that promotes seamless academic progression. However, in the United States, the overall PhD completion rate is only 57%. This article reports on the process undertaken by a collegial support group of students in a PhD in nursing science program who encouraged each other's progress through the dissertation process within a calendar year.

  11. Shrinkage Degree in $L_{2}$ -Rescale Boosting for Regression.

    Science.gov (United States)

    Xu, Lin; Lin, Shaobo; Wang, Yao; Xu, Zongben

    2017-08-01

    L 2 -rescale boosting ( L 2 -RBoosting) is a variant of L 2 -Boosting, which can essentially improve the generalization performance of L 2 -Boosting. The key feature of L 2 -RBoosting lies in introducing a shrinkage degree to rescale the ensemble estimate in each iteration. Thus, the shrinkage degree determines the performance of L 2 -RBoosting. The aim of this paper is to develop a concrete analysis concerning how to determine the shrinkage degree in L 2 -RBoosting. We propose two feasible ways to select the shrinkage degree. The first one is to parameterize the shrinkage degree and the other one is to develop a data-driven approach. After rigorously analyzing the importance of the shrinkage degree in L 2 -RBoosting, we compare the pros and cons of the proposed methods. We find that although these approaches can reach the same learning rates, the structure of the final estimator of the parameterized approach is better, which sometimes yields a better generalization capability when the number of sample is finite. With this, we recommend to parameterize the shrinkage degree of L 2 -RBoosting. We also present an adaptive parameter-selection strategy for shrinkage degree and verify its feasibility through both theoretical analysis and numerical verification. The obtained results enhance the understanding of L 2 -RBoosting and give guidance on how to use it for regression tasks.

  1. Where are the black-hole entropy degrees of freedom?

    International Nuclear Information System (INIS)

    Das, Saurya; Shankaranarayanan, S

    2007-01-01

    Understanding the area proportionality of black-hole entropy (the 'area law') from an underlying fundamental theory has been one of the goals of all models of quantum gravity. A key question that one asks is: where are the degrees of freedom giving rise to black-hole entropy located? Taking the point of view that entanglement between field degrees of freedom inside and outside the horizon can be a source of this entropy, we show that when the field is in its ground state, the degrees of freedom near the horizon contribute most to the entropy, and the area law is obeyed. However, when it is in an excited state, degrees of freedom far from the horizon contribute more significantly, and deviations from the area law are observed. In other words, we demonstrate that horizon degrees of freedom are responsible for the area law

    The 360 Degree Evaluation Model is one means to provide a comprehensive view of clinical competency and readiness for progression in an online nursing program. This pilot project aimed to evaluate the effectiveness of implementing a 360 Degree Evaluation of clinical competency of graduate advanced practice nursing students. The 360 Degree Evaluation, adapted from corporate industry, encompasses assessment of student knowledge, skills, behaviors and attitudes and validates student's progression from novice to competent. Cohort of advanced practice nursing students in four progressive clinical semesters. Graduate advanced practice nursing students (N = 54). Descriptive statistics and Jonckheere's Trend Test were used to evaluate OSCE's scores from graded rubric, standardized patient survey scores, student reflection and preceptor evaluation. We identified all students passed the four OSCEs during a first attempt or second attempt. Scaffolding OSCE's over time allowed faculty to identify cohort weakness and create subsequent learning opportunities. Standardized patients' evaluation of the students' performance in the domains of knowledge, skills and attitudes, showed high scores of 96% in all OSCEs. Students' self-reflection comments were a mix of strengths and weaknesses in their self-evaluation, demonstrating themes as students progressed. Preceptor evaluation scores revealed the largest increase in knowledge and learning skills (NONPF domain 1), from an aggregate average of 90% in the first clinical course, to an average of 95%. The 360 Degree Evaluation Model provided a comprehensive evaluation of the student and critical information for the faculty ensuring individual student and cohort data and ability to analyze cohort themes.

    One could argue from a business prospective that colleges and universities are not working hard enough to train students for life in the business and civic world, at either the undergraduate or graduate levels. What is it that employers are looking for in students? How different are the skills and attributes employers are looking for between undergraduate and graduate students? How unique are the geosciences in this respect? At the undergraduate level recruiters have spoken loud and clear about what they want. According to the dean of the business school here at the University of Arizona, recruiters at the undergraduate degree level in business base less than half of their hiring decision on specific content knowledge in the discipline, and correspondingly more than half on the so-called soft skills ... ability to apply knowledge in new situations, ability to think critically, ability to communicate with others in both written and oral forms, ability to work in teams, ability to work with a diverse set of employees and customers (especially, but not limited to, the global job market), etc. How true is this at the graduate level, where students have typically spent 4-6 years specializing in a discipline? Is there a set of fundamental knowledge that employers are looking for at the graduate level? Are the so-called soft skills correspondingly less important? I will present results from a survey of graduate programs and industry recruiters addressing these questions, and highlight the areas of overlap and difference between undergraduates and graduates looking for jobs. I will concentrate specifically on jobs in the oil industry and on both masters and Ph.D. programs.

    The Dual Degree Partnership in Nursing (DDPN) is a unique articulation model created in 2005 between two nursing programs that provides a seamless pathway for students to earn both an associate's degree and a bachelor's degree in nursing while benefiting from the strengths of each program. Archival data has been systematically collected for a decade on admission, progression, retention, satisfaction, graduation, and NCLEX-RN pass rates to measure the reliability, validity, and integrity of this DDPN model for nursing education. The findings demonstrate consistent performance and positive outcomes on all factors measured, which have been benchmarked against available state and national results. This innovative approach to academic progression in nursing is replicable and serves as a prototype to educate more nurses at the baccalaureate level, which directly contributes to the Institute of Medicine's goal of 80% of RNs having a minimum of a bachelor's degree by 2020.

    Full Text Available Purpose: The purpose of this study was to determine whether practicing athletic trainers (ATs were using the stepwise progression to make return-to-play (RTP decisions after concussion and to determine what factors influenced their decision to use the stepwise progression. Methods: A total of 166 ATs (response rate = 16.6% completed a 21-item questionnaire that evaluated participant demographics, methods of concussion management, and RTP decision-making using the stepwise progression. Descriptive statistics and a logistic regression were completed to analyze data. Results: Factors such as education level (p = 0.05 and number of concussions treated (p = 0.05 predicted use of the stepwise progression, whereas sex (p = 0.17, employment setting (p = 0.17, state law (p = 0.86, and years practicing (p = 0.17 did not predict whether ATs were following the stepwise progression. Conclusion: The majority of the ATs from this study are employing the stepwise progression to safely return athletes to play after sustaining a concussion. This demonstrates that ATs are providing a standard of care for concussed athletes across various athletic training settings; however, having a graduate degree and treating more concussions per year are predictors of whether an AT follows all steps of the stepwise progression.

    Equinus in patients with cerebral palsy results from at least two factors: excessive contracture of the triceps surae and muscle retraction. Tendon surgery and progressive lengthening techniques using plaster walking boots can provide variable improvement in retraction. We compared the effect of this technique when applied with or without prior 40 degrees C warming in the same patients. We also assessed the efficacy of this treatment method in terms or degree of retraction, patient age, puberty maturity, and sex. This series included 70 muscles in 52 patients with cerebral palsy aged 2 years 11 months to 21 years (mean 8 years 3 months). Common features in these patients were: - equinus mainly explained by triceps retraction, - no history of prior surgery on the triceps tendon, - knee flexion less than 15 degrees in the upright position, - easily reduced lateral deformation of the foot, - absence of mediotarsal dislocation, - triceps stretching could be achieved without triggering unacceptably intense contracture. The retraction of the triceps surae was measured from the maximal passive dorsal flexion angle of the foot, before and after applying each stretching boot. The difference between these measurements gave the gain obtained with the plaster boot. Protocol R- (stretching with plaster boot) consisted in a series of slow stretchings for 10 minutes before making the boot which was worn 7 days. Recurrent retraction in these same patients warranted another treatment within a delay of 3 to 17 months (mean delay 8.7 months). The same treatment then followed protocol R+ where the stretching was preceded by immersion of the segment in a 40 degrees C water bath for 10 minutes. Mean gain obtained with protocol R+ (warming) was 6.8 degrees knee extended and 7.1 degrees knee flexed. These differences were highly significant in both cases (p knee extended and for 32 muscles, knee flexed. The gain was not related to age, sex or puberty maturity. It was not related to the

    Regents College, created by the Board of Regents of the University of The State on New York in 1971, has been offering, since January 1985, AS and BS degrees in nuclear technology. The impetus for establishing the nuclear technology degrees came from nuclear utility management and had to do with the US Nuclear Regulatory Commission proposed rule regarding degreed operators on shift. There are a variety of ways to earn credits in Regents College degree programs: (1) college courses taken for degree-level credit from regionally accredited colleges; (2) courses sponsored by business, industry, or government that have been evaluated and recommended for credit by the New York National or American Council on Education (ACE's) Program on Noncollegiate Sponsored Instruction (PONSI); (3) military education that has been evaluated by ACE PONSI; (4) approved college-proficiency examinations; and (5) special assessment: an individualized examination of college-level knowledge gained from experience or independent study. Nuclear technology students primarily use college course work, evaluated military education, and proficiency examinations to complete degree programs. However, an increasing number of utilities are having training programs PONSI evaluated, resulting in an increased use of these courses in the nuclear technology degrees. Quality control is a function of several factors described in the paper

  12. Maximizing the Spread of Influence via Generalized Degree Discount.

    It is a crucial and fundamental issue to identify a small subset of influential spreaders that can control the spreading process in networks. In previous studies, a degree-based heuristic called DegreeDiscount has been shown to effectively identify multiple influential spreaders and has severed as a benchmark method. However, the basic assumption of DegreeDiscount is not adequate, because it treats all the nodes equally without any differences. To consider a general situation in real world networks, a novel heuristic method named GeneralizedDegreeDiscount is proposed in this paper as an effective extension of original method. In our method, the status of a node is defined as a probability of not being influenced by any of its neighbors, and an index generalized discounted degree of one node is presented to measure the expected number of nodes it can influence. Then the spreaders are selected sequentially upon its generalized discounted degree in current network. Empirical experiments are conducted on four real networks, and the results show that the spreaders identified by our approach are more influential than several benchmark methods. Finally, we analyze the relationship between our method and three common degree-based methods.

  13. Cyclic efforts to improve completion rates of masters’ degree students in nursing

    Full Text Available Supervisors at Higher Education Institutions are challenged to shorten throughput of Master’s degree students in nursing as researchers are needed to improve the art and science of the nursing profession. Globally the completion time for a postgraduate degree in the health sciences varies between 4.7 and 5.5 years. The purpose of the study was to describe strategies that were implemented to shorten completion time and attrition rate of postgraduate students. A cyclic technical, scientific collaborative mode within an action research methodology was used to identify factors impeding completion time in this study. Contrary to other studies, supervision was not an inhibiting factor in this study. Physical, technical, academic and financial aspects were identified by postgraduate students through questionnaires and informal discussion groups with supervisors as well as progress reports. Strategies were implemented to address these. Following implementation of all strategies, 42% of the postgraduate students in the School of Nursing completed their Master’s degree within two years. This implies a 34% improvement. Although the completion rate improved it was still unsatisfactory and new challenges were identified during the second cycle, for example, the number of inexperienced supervisors increased and they needed mentoring. Speed mentoring is a possible solution to the problem.

    The effects of ionizing radiation at doses of 0.5 and 1.0 kGy were evaluated in mango cultivar Tommy Atkins when harvested at maturation stage showing yellow flesh and skin color more red than green, representing four degree of maturation at commercial scale. The fruits were stored for 21 days at 12 degree C and sensory evaluated after that period as its external appearance, internal appearance, acidic taste, sweet taste, mellow flavor, aroma, texture and succulence of the flesh, by a team of ten trained judges. Physic chemical analysis of the main characteristics of fruits quality were also performed in the pulp at the end of storage. The results of sensory analysis revealed that the doses used did not damaged the sensory characteristics of mango fruit and that they received a dose of 0.5 kGy showed higher acceptance for most sensory attributes evaluated. The physic chemical characteristics showed no significant differences between the doses, except the amount of ascorbic acid that decreased progressively with increasing doses. Application of this method is viable for mango cultivar Tommy Atkins when taken with a higher degree of maturity and was safe for the external market and sensory acceptable. (author)

    1989-11-01

    Rates of progression of renal failure were calculated for a group of 277 patients who had five or more clinic visits. The goals of therapy in the absence of ongoing immunological processes were control of blood pressure to diastolic pressures less than 85 mm Hg and serum phosphate less than 1.60 mmol/L (5 mg/dL). The mean rate of progression expressed as the slope of the reciprocal creatinine versus time was -0.0054 +/- 0.0009 dL/mg/mo (mean +/- SEM), and the median was -0.00315 dL/mg/mo. Approximately 25% of these patients had rates of progression less than -0.001 dL/mg/mo. The rate of progression was inversely correlated with the creatinine concentration at entry (P less than 0.004) and with the frequency of clinic visits (P less than 0.01). The "renal survival" time from a creatinine of 880 mumol/L (10 mg/dL) to dialysis was 10.0 +/- 1.2 months (mean +/- SEM). These data provide rates of progression for a group of patients without specific dietary intervention but with vigorous control of blood pressure and phosphorus.

  17. The master degree: A critical transition in STEM doctoral education

    Science.gov (United States)

    Lange, Sheila Edwards

    The need to broaden participation in the nation's science, technology, engineering, and mathematics (STEM) undergraduate and graduate programs is currently a matter of national urgency. The small number of women and underrepresented minorities (URM) earning doctoral degrees in STEM is particularly troubling given significant increases in the number of students earning master's degrees since 1990. In the decade between 1990 and 2000, the total number of master's recipients increased by 42%. During this same time period, the number of women earning master's degrees increased by 56%, African Americans increased by 132%, American Indians by 101%, Hispanics by 146%, and Asian Americans by 117% (Syverson, 2003). Growth in underrepresented group education at the master's level raises questions about the relationship between master's and doctoral education. Secondary data analysis of the Survey of Earned Doctorates (SED) was used to examine institutional pathways to the doctorate in STEM disciplines and transitions from master's to doctoral programs by race and gender. While the study revealed no significant gender differences in pathways, compared to White and Asian American students, URM students take significantly different pathways to the doctorate. URM students are significantly more likely to earn the bachelor's, master's, and doctoral degrees at three different institutions. Their path is significantly more likely to include earning a master's degree en route to the doctorate. Further, URM students are more likely to experience transition between the master's and doctoral degrees, and the transitions are not limited to those who earn master's degrees at master's-only institutions. These findings suggest that earning a master's degree is more often a stepping stone to the doctorate for URM students. Master's degree programs, therefore, have the potential to be a valuable resource for policymakers and graduate programs seeking to increase the diversity of URM students

  18. Protograph LDPC Codes with Node Degrees at Least 3

    Divsalar, Dariush; Jones, Christopher

    2006-01-01

    In this paper we present protograph codes with a small number of degree-3 nodes and one high degree node. The iterative decoding threshold for proposed rate 1/2 codes are lower, by about 0.2 dB, than the best known irregular LDPC codes with degree at least 3. The main motivation is to gain linear minimum distance to achieve low error floor. Also to construct rate-compatible protograph-based LDPC codes for fixed block length that simultaneously achieves low iterative decoding threshold and linear minimum distance. We start with a rate 1/2 protograph LDPC code with degree-3 nodes and one high degree node. Higher rate codes are obtained by connecting check nodes with degree-2 non-transmitted nodes. This is equivalent to constraint combining in the protograph. The condition where all constraints are combined corresponds to the highest rate code. This constraint must be connected to nodes of degree at least three for the graph to have linear minimum distance. Thus having node degree at least 3 for rate 1/2 guarantees linear minimum distance property to be preserved for higher rates. Through examples we show that the iterative decoding threshold as low as 0.544 dB can be achieved for small protographs with node degrees at least three. A family of low- to high-rate codes with minimum distance linearly increasing in block size and with capacity-approaching performance thresholds is presented. FPGA simulation results for a few example codes show that the proposed codes perform as predicted.

Intranasal Insulin Therapy for Alzheimer Disease and Amnestic Mild Cognitive Impairment: A Pilot Clinical Trial. Arch Neurol . 2011 Sep 12. Alzheimer's disease is associated with brain insulin deficiency and insulin resistance, similar to the problems in diabetes. If insulin could be supplied to the brain in the early stages of Alzheimer's, subsequent neurodegeneration might be prevented. Administering systemic insulin to elderly non-diabetics poses unacceptable risks of inadvertant hypoglycemia. However, intranasal delivery directs the insulin into the brain, avoiding systemic side-effects. This pilot study demonstrates both efficacy and safety of using intranasal insulin to treat early Alzheimer's and mild cognitive impairment, i.e. the precursor to Alzheimer's. Significant improvements in learning, memory, and cognition occured within a few months, but without intranasal insulin, brain function continued to deteriorate in measurable degrees. Intranasal insulin therapy holds promise for halting progression of Alzheimer's disease.

    We have studied the effects of degree correlation on congestion pressure in scale-free gradient networks. It is observed that the jamming coefficient J is insensitive to the degree correlation coefficient r for assortative and strongly disassortative scale-free networks, and J markedly decreases with an increase in r for weakly disassortative scale-free networks. We have also investigated the effects of degree correlation on the topology structure of scale-free gradient networks, and discussed the relation between the topology structure properties and transport efficiency of gradient networks.

    The inversion degree of a series of nanocrystalline samples of CoFe 2 O 4 ferrites has been evaluated by a combined study, which exploits the saturation magnetization at 4.2 K and 57 Fe Moessbauer spectroscopy. The samples, prepared by sol-gel autocombustion, have different thermal history and particle size. The differences observed in the saturation magnetization of these samples are explained in terms of different inversion degrees, as confirmed by the analysis of the components in the Moessbauer spectra. It is notable that the inversion degrees of the samples investigated are set among the highest values reported in the literature.

    Tracking Clean Energy Progress 2013 (TCEP 2013) examines progress in the development and deployment of key clean energy technologies. Each technology and sector is tracked against interim 2020 targets in the IEA Energy Technology Perspectives 2012 2°C scenario, which lays out pathways to a sustainable energy system in 2050. Stark message emerge: progress has not been fast enough; large market failures are preventing clean energy solutions from being taken up; considerable energy efficiency remains untapped; policies need to better address the energy system as a whole; and energy-related research, development and demonstration need to accelerate. Alongside these grim conclusions there is positive news. In 2012, hybrid-electric vehicle sales passed the 1 million mark. Solar photovoltaic systems were being installed at a record pace. The costs of most clean energy technologies fell more rapidly than anticipated.

    A woman aged 77 years was transferred to our neurocritical care unit for evaluation and treatment of rapidly progressive motor weakness and encephalopathy. Examination revealed an ability to follow simple commands only and abnormal movements, including myoclonus, tongue and orofacial dyskinesias, and opsoclonus. Imaging study findings were initially unremarkable, but when repeated, they demonstrated enhancement of the cauda equina nerve roots, trigeminal nerve, and pachymeninges. Cerebrospinal fluid examination revealed mildly elevated white blood cell count and protein levels. Serial electrodiagnostic testing demonstrated a rapidly progressive diffuse sensory motor axonopathy, and electroencephalogram findings progressed from generalized slowing to bilateral periodic lateralized epileptiform discharges. Critical details of her recent history prompted a diagnostic biopsy. Over time, the patient became completely unresponsive with no further abnormal movements and ultimately died. The differential diagnosis, pathological findings, and diagnosis are discussed with a brief review of a well-known yet rare diagnosis.

    The author discusses international progress in fusion research during the last three years. Much of the technical progress has been achieved through international collaboration in magnetic fusion research. This progress has stimulated political interest in a multinational effort, aimed at designing and possibly constructing the world's first experimental fusion reactor. This interest was reflected in recent summit-level discussions involving President Mitterand, General Secretary Gorbachev, and President Reagan. Most recently, the European Community (EC), Japan, the United States, and the U.S.S.R. have decided to begin serious preparation for taking the next step toward practical fusion energy. These parties have agreed to begin the design and supporting R and D for an International Thermonuclear Experimental Reactor (ITER) under the auspices of the International Atomic Energy Agency (IAEA). The initiation of this international program to prepare for a fusion test reactor is discussed

    Forecasting technological progress is of great interest to engineers, policy makers, and private investors. Several models have been proposed for predicting technological improvement, but how well do these models perform? An early hypothesis made by Theodore Wright in 1936 is that cost decreases as a power law of cumulative production. An alternative hypothesis is Moore's law, which can be generalized to say that technologies improve exponentially with time. Other alternatives were proposed by Goddard, Sinclair et al., and Nordhaus. These hypotheses have not previously been rigorously tested. Using a new database on the cost and production of 62 different technologies, which is the most expansive of its kind, we test the ability of six different postulated laws to predict future costs. Our approach involves hindcasting and developing a statistical model to rank the performance of the postulated laws. Wright's law produces the best forecasts, but Moore's law is not far behind. We discover a previously unobserved regularity that production tends to increase exponentially. A combination of an exponential decrease in cost and an exponential increase in production would make Moore's law and Wright's law indistinguishable, as originally pointed out by Sahal. We show for the first time that these regularities are observed in data to such a degree that the performance of these two laws is nearly the same. Our results show that technological progress is forecastable, with the square root of the logarithmic error growing linearly with the forecasting horizon at a typical rate of 2.5% per year. These results have implications for theories of technological change, and assessments of candidate technologies and policies for climate change mitigation. PMID:23468837

    Full Text Available Objectives: The aim of the study was the epidemiological analysis and evaluation of selected clinical and sociodemographic factors in Polish patients with primary progressive multiple sclerosis. Methods: The study included patients from 7 provinces in central and eastern Poland registered in the Registry of Patients with Multiple Sclerosis on 31 December 2016. The incidence of various forms of the disease was compared, and clinical, demographic and social disparities between relapsing-remitting and primary progressive multiple sclerosis were analysed. Results: Of 3,199 registered patients, 2,188 persons (66.2% had the relapsing-remitting form of multiple sclerosis, 774 (24.2% had the secondary progressive type and 307 (9.6% suffered from primary progressive disease. The first symptoms of primary progressive multiple sclerosis appeared almost 10 years later than in patients with the relapsing-remitting type (39.2 ± 11.4 vs. 29.8 ± 9.8. The period from the first symptoms to diagnosis was more than twice as long in patients with primary progressive multiple sclerosis (5.8 ± 3.4 as in those with relapsing-remitting disease (2.4 ± 1.6. The average degree of disability in the Expanded Disability Status Scale was similar and amounted to 3.2 ± 2.1 for relapsing-remitting and 3.6 ± 2.4 for primary progressive multiple sclerosis. The relapsing-remitting form was observed more often in women (2.4:1, and the primary progressive form appeared with equal frequency in both sexes (1:1. Disease-modifying treatment was received by 34% of patients with relapsing-remitting and in only 1.9% of patients with primary progressive multiple sclerosis. Conclusions: The primary progressive form affects approximately 10% of Polish patients with multiple sclerosis. The first symptoms appear at about 40 years of age with equal frequency in both sexes, and its diagnosis takes more than twice as much time as in the case of relapsing-remitting multiple

    2016-12-01

    Full Text Available We explore the effective degrees of freedom in the early Universe, from before the electroweak scale at a few femtoseconds after the Big Bang until the last positrons disappeared a few minutes later. We look at the established concepts of effective degrees of freedom for energy density, pressure, and entropy density, and introduce effective degrees of freedom for number density as well. We discuss what happens with particle species as their temperature cools down from relativistic to semi- and non-relativistic temperatures, and then annihilates completely. This will affect the pressure and the entropy per particle. We also look at the transition from a quark-gluon plasma to a hadron gas. Using a list a known hadrons, we use a “cross-over” temperature of 214 MeV, where the effective degrees of freedom for a quark-gluon plasma equals that of a hadron gas.

    2012-10-01

    We report the success of a unique articulation Dual Degree Partnership in Nursing (DDPN) model. The process used to establish and implement this approach is described. Unlike typical 2+2 agreements between associate degree (AD) and bachelor degree (BS) nursing education programs, the DDPN is designed with a 1+2+1 sequence. Intended to attract high school students, this model provides the opportunity to earn two degrees (AD and BS) while experiencing a 4-year campus living and learning environment. This configuration was accomplished without compromising the integrity of either of the established programs. After collecting data over the past 6 years, this model demonstrates popularity with the traditional-aged student, as well as success from an academic perspective. Statistics on retention, graduation, and NCLEX® pass rates indicate the feasibility and success of the model. Based on the findings, the potential for replication is promising for other colleges interested in a similar collaboration. Copyright 2012, SLACK Incorporated.

  9. Mixed-Degree Spherical Simplex-Radial Cubature Kalman Filter

    Directory of Open Access Journals (Sweden)

    Shiyuan Wang

    2017-01-01

    Full Text Available Conventional low degree spherical simplex-radial cubature Kalman filters often generate low filtering accuracy or even diverge for handling highly nonlinear systems. The high-degree Kalman filters can improve filtering accuracy at the cost of increasing computational complexity; nevertheless their stability will be influenced by the negative weights existing in the high-dimensional systems. To efficiently improve filtering accuracy and stability, a novel mixed-degree spherical simplex-radial cubature Kalman filter (MSSRCKF is proposed in this paper. The accuracy analysis shows that the true posterior mean and covariance calculated by the proposed MSSRCKF can agree accurately with the third-order moment and the second-order moment, respectively. Simulation results show that, in comparison with the conventional spherical simplex-radial cubature Kalman filters that are based on the same degrees, the proposed MSSRCKF can perform superior results from the aspects of filtering accuracy and computational complexity.

    Firefighters experience significant heat stress while working with heavy gear in a hot, humid environment. This study compared the cooling effectiveness of immersing the forearms and hands in 10 and 20 degrees C water. Six men (33 +/- 10 yr; 180 +/- 4 cm; 78 +/- 9 kg; 19 +/- 5% body fat) wore firefighter 'turn-out gear' (heavy clothing and breathing apparatus weighing 27 kg) in a protocol including three 20-min exercise bouts (step test, 78 W, 40 degrees C air, 40% RH) each followed by a 20-min rest/cooling (21 degrees C air); i.e., 60 min of exercise, 60 min of cooling. Turn-out gear was removed during rest/cooling periods and subjects either rested (Control), immersed their hands in 10 or 20 degrees C water (H-10, H-20), or immersed their hands and forearms in 10 or 20 degrees C water (HF-10, HF-20). In 20 degrees C water, hand immersion did not reduce core temperature compared with Control; however, including forearm immersion decreased core temperature below Control values after both the second and final exercise periods (p hand immersion produced a lower core temperature (0.8 degrees C above baseline) than all other conditions (1.1 to 1.4 degrees C above baseline) after the final exercise period (p Hand and forearm immersion in cool water is simple, reduces heat strain, and may increase work performance in a hot, humid environment. With 20 degrees C water, forearms should be immersed with the hands to be effective. At lower water temperatures, forearm and/or hand immersion will be effective, although forearm immersion will decrease core temperature further.

  15. Are UK undergraduate Forensic Science degrees fit for purpose?

    Science.gov (United States)

    Welsh, Charles; Hannis, Marc

    2011-09-01

    In October 2009 Skills for Justice published the social research paper 'Fit for purpose?: Research into the provision of Forensic Science degree programmes in UK Higher Education Institutions.' The research engaged employers representing 95% of UK Forensic Science providers and 79% of UK universities offering Forensic Science or Crime Scene degree programmes. In addition to this, the research collected the views of 430 students studying these degrees. In 2008 there were approximately 9000 people working in the Forensic Science sector in the UK. The research found that the numbers of students studying Forensic Science or Crime Scene degrees in the UK have more than doubled since 2002-03, from 2191 in to 5664 in 2007-08. Over the same period there were twice as many females as males studying for these degrees. The research concluded that Forensic Science degree programmes offered by UK universities were of a good quality and they provided the student with a positive learning experience but the content was not relevant for Forensic Science employers. This echoed similar research by the former Government Department for Innovation, Universities and Skills on graduates from wider science, technology, engineering and mathematics degree programmes. The research also found that 75% of students studying Forensic Science or Crime Scene degrees expected to have a career in the Forensic Science sector, meaning that ensuring these courses are relevant for employers is a key challenge for universities. This paper reflects on the original research and discusses the implications in light of recent government policy. Copyright © 2011 Forensic Science Society. Published by Elsevier Ireland Ltd.

    The value of a college degree is often quantified as the difference in earnings between those with and without a degree. The research presented here operationalizes this idea in two important ways. First, since future income and tuition are uncertain, a contingent claims model is developed and the appropriate discount rate for valuing future earnings is, therefore, endogenized given an economy that does not permit arbitrage. Second, the model is sensitive to the valuation of the real option t...

Patients and methods: This prospective, interventional and observational case series included 294 patients scheduled for cataract removal by phacoemulsification technique. Patients with nuclear cataracts of grade 4 and 5 nuclear opalescence of Lens Opacities Classification System III were included in the study. Patients were consecutively allocated to phaco chop technique with 0-degree (0-degree group, n=147 and combined bevel up and down position using 30-degree phaco tip (combined bevel up/down group, n=147. The 0-degree group had phacoemulsification with 0-degree phaco tip, while the 30-degree group had chopping of the nucleus with bevel down phaco tip and emulsification of nuclear fragments was accomplished with bevel up tip. EPT, CDE, NET and intraoperative complications were noted and compared between the groups using analysis of variance. Results: Average EPT, CDE and NET were lower in the 30-degree group than in the 0-degree group. However, no statistically significant difference was found in EPT (P=0.0733, CDE (P=0.0663 and NET (P=0.0633 between the two groups. No serious intraoperative complications were noted. The anterior chamber was maintained throughout the procedure in both groups. No patients had wound burn and miosis during the procedure. None of the patients developed bullous keratopathy, uveitis and cystoid macular edema during the follow-up period. Conclusion: Combined bevel up and down 30-degree tip can yield effective hard nucleus phacoemulsification. Bevel down tip of 30-degree helps in effective chopping and bevel up tip assists in emulsification of the nuclear fragments. Although combined bevel up and down 30

    Aim To determine whether matrix metalloproteinase-9 (MMP-9) may be a useful adjunctive tool for predicting unfavorable biological behavior of papillary thyroid carcinoma (PTC) by evaluating the expression profile and proteolytic activity of MMP-9 in PTC by different techniques and correlating the findings with clinicopathological prognostic factors. Methods Immunohistochemical localization of MMP-9 was analyzed with antibodies specific for either total or active MMP-9. Activation ratios of MMP-9 were calculated by quantifying gel zymography bands. Enzymatic activity of MMP-9 was localized by in situ zymography after inhibiting MMP-2 activity. Results Immunostaining of total and active MMP-9 was observed in tumor tissue and occasionally in non-neoplastic epithelium. Only active MMP-9 was significantly associated with extrathyroid invasion, lymph-node metastasis, and the degree of tumor infiltration (P zymography revealed a correlation between the MMP-9 activation ratio and nodal involvement, extrathyroid invasion, and the degree of tumor infiltration. In situ zymography showed that gelatinases exerted their activity in tumor parenchymal and stromal cells. Moreover, after application of MMP-2 inhibitor, the remaining gelatinase activity, corresponding to MMP-9, was highest in cancers with the most advanced degree of tumor infiltration. Conclusions This is the first report suggesting that the evaluation of active MMP-9 by immunohistochemistry and determination of its activation ratio by gelatin zymography may be a useful adjunct to the known clinicopathological factors in predicting tumor behavior. Most important, in situ zimography with an MMP-2 inhibitor for the first time demonstrated a strong impact of MMP-9 activity on the degree of tumor infiltration during PTC progression. PMID:24778099

    Steven Pinker, a cognitive psychologist and linguist at Harvard and a savant of big ideas, is one of the latest to take on the idea of progress. He does it under the aegis of "enlightenment," which comes down to a kind of holy trinity of reason, science, and humanism. His new book, Enlightenment Now: The Case for Reason, Science, Humanism, and Progress, is ambitious and cantankerous and heady with hope. On the whole, Pinker makes a good case for the benefits of progress, but with an overdose of feel-good prose. His greatest failure comes in exaggerating the threats to science and in avoiding some problems altogether. He ignores its complexity, its shadows, its creation of new problems raised by its solutions to old ones. Pinker has a particular animus against bioethics, and he misses what has been, I would argue, at the heart of bioethics from its beginning fifty or so years ago. Bioethics was prompted by a new class of medical dilemmas that require a difficult balancing of harms and benefits. Most of them are still with us, and most of them are the result of the progress of postwar medical research and fast-changing clinical practices. © 2018 The Hastings Center.

    Progressive supranuclear palsy (PSP) is a Parkinson-plus syndrome characterized clinically by supranuclear ophthalmoplegia, pseudobulbar palsy, axial rigidity, bradykinesia, postural instability and dementia. Presence of dementia and lack of cortical histopathology suggest the derangement of cortical function by pathological changes in subcortical structures in PSP, which is supported by the pattern of behavioral changes and measurement of brain metabolism using positron emission tomography. This study was done to examine whether there are specific changes of regional cerebral perfusion in PSP and whether there is a correlation between severity of motor abnormaility and degree of changes in cerebral perfusion. We measured regional cerebral perfusion indices in 5 cortical and 2 subcortical areas in 6 patients with a clinical diagnosis of PSP and 6 healthy age and sex matched controls using Tc-99m-HMPAO SPECT. Compared with age and sex matched controls, only superior frontal regional perfusion index was significantly decreased in PSP (p<0.05). There was no correlation between the severity of the motor abnormality and any of the regional cerebral perfusion indices (p>0.05). We affirm the previous reports that perfusion in superior frontal cortex is decreased in PSP. Based on our results that there was no correlation between severity of motor abnormality and cerebral perfusion in the superior frontal cortex, nonmotoric symptoms including dementia needs to be looked at whether there is a correlation with the perfusion abnormality in superior frontal cortex

  7. Progress on nuclear modifications of structure functions

    Kumano S.

    2016-01-01

    Full Text Available We report progress on nuclear structure functions, especially on their nuclear modifications and a new tensor structure function for the deuteron. To understand nuclear structure functions is an important step toward describing nuclei and QCD matters from low to high densities and from low to high energies in terms of fundamental quark and gluon degrees of freedom beyond conventional hadron and nuclear physics. It is also practically important for understanding new phenomena in high-energy heavy-ion collisions at RHIC and LHC. Furthermore, since systematic errors of current neutrinooscillation experiments are dominated by uncertainties of neutrino-nucleus interactions, such studies are valuable for finding new physics beyond current framework. Next, a new tensor-polarized structure function b1 is discussed for the deuteron. There was a measurement by HERMES; however, its data are inconsistent with the conventional convolution estimate based on the standard deuteron model with D-state admixture. This fact suggests that a new hadronic phenomenon should exist in the tensor-polarized deuteron at high energies, and it will be experimentally investigated at JLab from the end of 2010’s.

  8. Progression of scoliosis in patients with spastic quadriplegia after the insertion of an intrathecal baclofen pump.

    Ginsburg, Glen M; Lauder, Anthony J

    2007-11-15

    Medical and radiographic review of 19 consecutive patients with spastic quadriplegia before and after intrathecal baclofen pump insertion with special attention paid to progression of scoliosis. Many orthopedic surgeons who treat spastic quadriplegic patients have noticed a trend of marked scoliosis progression after the administration of intrathecal baclofen (ITB) via subcutaneous pump and catheter. The purpose of this study is to quantify scoliosis progression in this patient population before and after baclofen administration and compare this to published natural history data. The authors had noted rapid progression of scoliosis in spastic quadriplegic patients after intrathecal baclofen pump insertion. This had been noted at other centers, but no significant statistical analysis had been done comparing prepump to postpump scoliosis progression in these patients. To document the magnitude and rate of scoliosis progressions after the placement of an ITB pump, the charts and radiographs of 19 consecutive nonambulatory patients with spastic quadriplegia and an ITB pump were reviewed. To document the rate of scoliosis progression, each patient had at least 2 pre and 2 postpump insertion spinal radiographs made. All radiographs were made with the patients in the supine position without orthoses. A board-certified orthopedic surgeon reviewed these radiographs. Skeletal maturity was assessed using Risser grading. Catheter tip location and rate of baclofen administration were recorded. For 19 patients with complete radiographic data, average Cobb angles were 10.2 degrees before pump insertion and 25 degrees at an average of 20.9 months after pump insertion (P quadriplegia and ITB pump. The authors are now performing spinal fusions for curves that exceed 40 degrees to 50 degrees in the presence of an ITB pump as recommended by previous reviews of scoliosis and accompanying quadriplegia.

    Patients with progressive multiple sclerosis (MS) often have cognitive impairment in addition to physical impairment. The burden of cognitive and physical impairment progresses over time, and may be major determinants of quality of life. The aim of this study was to assess to which degree quality of life correlates with physical and cognitive function in progressive MS. This is a retrospective study of 52 patients with primary progressive ( N  = 18) and secondary progressive MS ( N  = 34). Physical disability was assessed using the Expanded Disability Status Scale, Timed 25 Foot Walk (T25FW) test and 9-Hole Peg Test (9HPT). Cognitive function was assessed using Symbol Digit Modalities Test (SDMT), Paced Auditory Serial Addition Test, and Trail Making Test B (TRAIL-B). In addition, quality of life was assessed by the Short Form 36 (SF-36) questionnaire. Only measures of cognitive function correlated with the overall SF-36 quality of life score and the Mental Component Summary score from the SF-36. The only physical measure that correlated with a measure of quality of life was T25FW test, which correlated with the Physical Component Summary from the SF-36. We found no other significant correlations between the measures of cognitive function and the overall physical measures but interestingly, we found a possible relationship between the 9HPT score for the nondominant hand and the SDMT and TRAIL-B. Our findings support inclusion of measures of cognitive function in the assessment of patients with progressive MS as these correlated closer with quality of life than measures of physical impairment.

    Chemical sensor is made of up transducer that transfers the part and signal recognizing the measurement objects. Biosensor that normally transfers the amount of chemicals into electrical signal is a sensor in which living materials like enzyme, microorganism or antigen, antibody and so forth are used in the recognition part. Recently, the structure or the function of the living materials is clarified gradually with the significant progress in biofeedback, however, the synthesis of artificial material having same function as that of living materials is extremely difficult. Accordingly, it is very practical to develop high degree sensor function by using living materials with developed function in material recognition part, an important element of the sensor. In this report, solid state biosensor using electrode as a transducer is focused, and specially, recent research progress regarding the amperometric measurement which measures oxidation/reduction current is discussed. 35 refs., 8 figs., 1 tab.

  12. [Burnout effect on academic progress of Oncology medical residents].

    González-Ávila, Gabriel; Bello-Villalobos, Herlinda

    2014-01-01

    In the formative period of the courses taken in medical specializations, new and greater responsibilities are accepted by physicians in personal and academic spheres. The interaction of several factors that encompass the practice of these physicians could surpass their capacity to cope, causing on these professionals a high level of stress and professional exhaustion, which will affect their academic development. The objective of this research was to establish if the occupational stress of these medical residents affects their academic progress. We administered the Spanish version of the Maslach Burnout Inventory (MBI) to 52 residents of three specializations in Oncology (Medical Oncology, Surgical Oncology, and Radio-Oncology). These residents accepted voluntarily at the same time of their third cognitive exam. The prevalence of burnout syndrome was 13.5 %, with a high frequency among medical residents of first degree. Medical Oncology residents showed a higher emotional exhaustion and lower personal fulfillment. Considering the three specializations, the academic progress was higher in the third year, with a significant difference to Surgical Oncology and Medical Oncology (p = 0.026 and 0.015, respectively). No significant difference was found between burnout syndrome, academic progress and sociodemographic characteristics. The presence of burnout syndrome does not affect the academic progress of Oncology medical residents.

    This final chapter of the book lists advances in elementary particle theory from 1950 to 1964 in an order of progressive understanding of ideas rather than chronologically. Starting with quantum field theory and the important discoveries within it, the author explains the connections and items missing in this decade, but understood later. The second part of the chapter takes the same pattern, but deals with basic interactions (strong, electromagnetic, weak and gravitational) and elementary particles, including quarks. By 1985, theory had developed to such a degree that it was hoped that the long-sought-after unified field theory of all elementary particles and interactions of nature might be close at hand. (UK)

    This study isolated the effects of dorsal, facial, and whole-head immersion in 17 degrees C water on peripheral vasoconstriction and the rate of body core cooling. Seven male subjects were studied in thermoneutral air (approximately 28 degrees C). On 3 separate days, they lay prone or supine on a bed with their heads inserted through the side of an adjustable immersion tank. Following 10 min of baseline measurements, the water level was raised such that the water immersed the dorsum, face, or whole head, with the immersion period lasting 60 min. During the first 30 min, the core (esophageal) cooling rate increased from dorsum (0.29 ± 0.2 degrees C h-1) to face (0.47 ± 0.1 degrees C h-1) to whole head (0.69 ± 0.2 degrees C h(-1)) (p whole-head immersion (114 ± 52% h(-1)) than in either facial (51 ± 47% h-1) or dorsal (41 ± 55% h(-1)) immersion (p whole-head (120.5 ± 13 kJ), facial (86.8 ± 17 kJ), and dorsal (46.0 ± 11 kJ) immersion (p whole head elicited a higher rate of vasoconstriction, the face did not elicit more vasoconstriction than the dorsum. Rather, the progressive increase in core cooling from dorsal to facial to whole-head immersion simply correlates with increased heat loss.

  15. A Degree Distribution Optimization Algorithm for Image Transmission

    Science.gov (United States)

    Jiang, Wei; Yang, Junjie

    2016-09-01

    Luby Transform (LT) code is the first practical implementation of digital fountain code. The coding behavior of LT code is mainly decided by the degree distribution which determines the relationship between source data and codewords. Two degree distributions are suggested by Luby. They work well in typical situations but not optimally in case of finite encoding symbols. In this work, the degree distribution optimization algorithm is proposed to explore the potential of LT code. Firstly selection scheme of sparse degrees for LT codes is introduced. Then probability distribution is optimized according to the selected degrees. In image transmission, bit stream is sensitive to the channel noise and even a single bit error may cause the loss of synchronization between the encoder and the decoder. Therefore the proposed algorithm is designed for image transmission situation. Moreover, optimal class partition is studied for image transmission with unequal error protection. The experimental results are quite promising. Compared with LT code with robust soliton distribution, the proposed algorithm improves the final quality of recovered images obviously with the same overhead.

  16. A critical reflection on subjectivity in examination of higher degrees

    Directory of Open Access Journals (Sweden)

    Collins C Ngwakwe

    2015-11-01

    Full Text Available This paper is a critical reflection on seemingly embedded subjectivity in external examination of higher degrees. The paper is significant given that education is a vital pillar of sustainable development; hence, identification of obscure obstacles to this goal is imperative for an equitable and sustainable education that is devoid of class, race and gender. Adopting a critical review approach, the paper rummaged some related researches that bemoan apparent subjectivity amongst some examiners of higher degrees. Findings show a regrettable and seemingly obscured subjectivity and/or misjudgement that constitute an impediment in higher degrees examination process. Thus the paper highlights that whilst it is understandable that misjudgement or error is innate in every human endeavour including higher degree examination, however an error caused by examiner’s partisanship and/or maladroitness in the research focus may be avoidable. In conclusion, the paper stresses that prejudice or ineptitude in higher degree examination should be bridled by inter alia implementing the policy of alternative assessor; checking the pedigree of examiner’s assessment experience and an opportunity for the supervisor/s to present a rebuttal in circumstances where one examiner’s opinion is fraught with apparent subjectivity.

  17. Geometric evolution of complex networks with degree correlations

    2018-03-01

    We present a general class of geometric network growth mechanisms by homogeneous attachment in which the links created at a given time t are distributed homogeneously between a new node and the existing nodes selected uniformly. This is achieved by creating links between nodes uniformly distributed in a homogeneous metric space according to a Fermi-Dirac connection probability with inverse temperature β and general time-dependent chemical potential μ (t ) . The chemical potential limits the spatial extent of newly created links. Using a hidden variable framework, we obtain an analytical expression for the degree sequence and show that μ (t ) can be fixed to yield any given degree distributions, including a scale-free degree distribution. Additionally, we find that depending on the order in which nodes appear in the network—its history—the degree-degree correlations can be tuned to be assortative or disassortative. The effect of the geometry on the structure is investigated through the average clustering coefficient 〈c 〉 . In the thermodynamic limit, we identify a phase transition between a random regime where 〈c 〉→0 when β 0 when β >βc .

    This article reports the results of research into the activities of lactic acid concentrations in the body fluids of children with progressive encephalopathies (PE) in comparison to patients with non-progressive encephalopathies (NPE) and those with non-progressive encephalopathies with concomitant epilepsy (NPEE). The study was designed to determine whether there is difference between the serum and CSF lactic acid concentrations in children with progressive encephalopathies (PE), static (non-progressive) encephalopathies (NPE) and non progressive encephalopathies with concomitant epilepsy (NPEE), and whether the clinical status correlates with the concentration of these biochemical markers in children with PE. The assessment involved 138 children of both sexes, whose age ranged between 8 months and 15 years, diagnosed and treated in the Neurology Department at the Pediatric Clinic of the Silesian Medical Academy in Katowice between 1995 and 1997. Lactate concentrations were determined in serum and cerebro-spinal fluid and analyzed statistically. The findings showed higher serum and CSF concentrations in children with PE than in patients who manifested non-progressive forms of encephalopathy. The degree of clinical symptom aggravation in PE children was likewise analyzed and compared to the values of lactate concentrations in body fluids; however, no correlation was found between these parameters. Children with progressive encephalopathies present higher lactate concentrations in serum and cerebrospinal fluid than patients with static (non-progressive) encephalopathy.

    Recent progress on the design and fabrication of the RFCC (RF and superconducting Coupling Coil) module for the international MICE (Muon Ionization Cooling Experiment) are reported. The MICE ionization cooling channel has two RFCC modules, each having four 201- MHz normal conducting RF cavities surrounded by one superconducting coupling coil (solenoid) magnet. The magnet is designed to be cooled by three cryocoolers. Fabrication of the RF cavities is complete; preparation for the cavity electro-polishing, low power RF measurements, and tuning are in progress at Lawrence Berkeley National Laboratory (LBNL). Fabrication of the cold mass of the first coupling coil magnet has been completed in China and the cold mass arrived at LBNL in late 2011. Preparations for testing the cold mass are currently under way at Fermilab. Plans for the RFCC module assembly and integration are being developed and are described.

Coal is noted to be a potentially heavy pollution source, and the presence of environmentally acceptable methods of use such as fluidized-bed combustion and gasification and liquefaction reached the prototype stage in 1981, MHD power generation was achieved in two U.S. plants, with severe corrosion problems remaining unsolved for the electrodes. Solar flat plate collectors sales amounted to 20 million sq ft in 1981, and solar thermal electric conversion systems with central receivers neared completion. Solar cells are progressing toward DOE goals of $.70/peak W by 1986, while wind energy conversion sales were 2000 machines in 1981, and the industry is regarded as maturing. Finally, geothermal, OTEC, and fusion systems are reviewed.

    The progress of the field of Heavy Ion Fusion has been documented in the proceedings of the series of International Symposia that, in recent years, have occurred every second year. The latest of these conferences was hosted by Gesellshaft fuer Schwerionenforshung (GSI) in Darmstadt, West Germany, June 28-30, 1988. For this report, a few highlights from the conference are selected, stressing experimental progress and prospects for future advances. A little extra time is devoted to report on the developments at the Lawrence Berkeley Laboratory (LBL) which is the center for most of the HIFAR program. The Director of the HIFAR program at LBL is Denis Keefe, who presented the HIF report at the last two of the meetings in this series, and in whose place the author is appearing now. 4 refs., 1 fig

  5. Progressive Supranuclear Palsy: an Update.

    Progressive supranuclear palsy (PSP) is a 4R tau neuropathologic entity. While historically defined by the presence of a vertical supranuclear gaze palsy and falls in the first symptomatic year, clinicopathologic studies identify alternate presenting phenotypes. This article reviews the new PSP diagnostic criteria, diagnostic approaches, and treatment strategies. The 2017 International Parkinson and Movement Disorder Society PSP criteria outline 14 core clinical features and 4 clinical clues that combine to diagnose one of eight PSP phenotypes with probable, possible, or suggestive certainty. Evidence supports the use of select imaging approaches in the classic PSP-Richardson syndrome phenotype. Recent trials of putative disease-modifying agents showed no benefit. The new PSP diagnostic criteria incorporating the range of presenting phenotypes have important implications for diagnosis and research. More work is needed to understand how diagnostic evaluations inform phenotype assessment and identify expected progression. Current treatment is symptomatic, but tau-based therapeutics are in active clinical trials.

  7. Persistence of Women in Online Degree-Completion Programs

    Directory of Open Access Journals (Sweden)

    Terry Müller

    2008-06-01

    Full Text Available Although online courses at postsecondary institutions promise adults access, flexibility, and convenience, many barriers to online learning remain. This article presents findings from a qualitative case study, which explored the phenomenon of undergraduate and graduate women learners’ persistence in online degree-completion programs at a college in the Northeast of the United States. Research questions asked why women learners persisted or failed to persist, and how factors supporting or hindering persistence influenced learners. Interviews with a purposeful sample of 20 participants revealed the complexity of variables affecting learners’ persistence to graduation. Findings suggested that multiple responsibilities, insufficient interaction with faculty, technology, and coursework ranked highest as barriers to women’s persistence. Strong motivation to complete degrees, engagement in the learning community, and appreciation for the convenience of an online degree-completion option facilitated persistence.

  8. Population equations for degree-heterogenous neural networks

    Science.gov (United States)

    Kähne, M.; Sokolov, I. M.; Rüdiger, S.

    2017-11-01

    We develop a statistical framework for studying recurrent networks with broad distributions of the number of synaptic links per neuron. We treat each group of neurons with equal input degree as one population and derive a system of equations determining the population-averaged firing rates. The derivation rests on an assumption of a large number of neurons and, additionally, an assumption of a large number of synapses per neuron. For the case of binary neurons, analytical solutions can be constructed, which correspond to steps in the activity versus degree space. We apply this theory to networks with degree-correlated topology and show that complex, multi-stable regimes can result for increasing correlations. Our work is motivated by the recent finding of subnetworks of highly active neurons and the fact that these neurons tend to be connected to each other with higher probability.

  9. Master's degree in nuclear engineering by videotaped courses

    1991-01-01

    In 1986, a group of northern midwest utilities met with faculty from the nuclear engineering department at the University of Wisconsin (UW) to discuss the possibility of offering graduate courses by videotape for academic credit and earning a master's degree. Four years later, two utility employees from Northern States Power (NSP) and Wisconsin Electric Power Companies (WEPCO) graduated from the University of Wisconsin with master's degrees earned entirely by taking videotape graduate courses at their individual nuclear power plant sites. Within these 4 years, more than a dozen videotaped graduate courses were developed by the faculty of the department in a formalized master's degree program in nuclear engineering and engineering physics. This paper outlines the program's development and its current features

  10. Hadronic degrees of freedom in relativistic heavy-ion collisions

    International Nuclear Information System (INIS)

    Otsuka, Naohiko

    2001-01-01

    Relativistic heavy-ion collisions at AGS energies are studied by using an new developed hadronic cascade model, HANDEL which includes a few hadronic degrees of freedom. The spectra of hadron-hadron, hadron-nucleus and nucleus-nucleus reactions at AGS energies are well reproduced by HANDEL. It is confirmed that the infinite matter described by HANDEL has particle fractions which are expected from grand canonical ensemble. When we compare the thermal evolution of Au+Au collision from HANDEL with the result from JAM which has larger hadronic degree of freedoms, we find both models give similar evolution of temperature, against naive expectation. We argue that this results can be interpretated if the particles in formation time works as the additional effective hadronic degrees of freedom. (author)

    2005-12-01

    The development of the Bioinformatics MS degree program at the University of Illinois, the challenges and opportunities associated with such a process, and the current structure of the program is described. This program has departed from earlier University practice in significant ways. Despite the existence of several interdisciplinary programs at the University, a few of which grant degrees, this is the first interdisciplinary program that grants degrees and formally recognises departmental specialisation areas. The program, which is not owned by any particular department but by the Graduate College itself, is operated in a franchise-like fashion via several departmental concentrations. With four different colleges and many more departments involved in establishing and operating the program, the logistics of the operation are of considerable complexity but result in significant interactions across the entire campus.

  12. Optimal satisfaction degree in energy harvesting cognitive radio networks

    International Nuclear Information System (INIS)

    Li Zan; Liu Bo-Yang; Si Jiang-Bo; Zhou Fu-Hui

    2015-01-01

    A cognitive radio (CR) network with energy harvesting (EH) is considered to improve both spectrum efficiency and energy efficiency. A hidden Markov model (HMM) is used to characterize the imperfect spectrum sensing process. In order to maximize the whole satisfaction degree (WSD) of the cognitive radio network, a tradeoff between the average throughput of the secondary user (SU) and the interference to the primary user (PU) is analyzed. We formulate the satisfaction degree optimization problem as a mixed integer nonlinear programming (MINLP) problem. The satisfaction degree optimization problem is solved by using differential evolution (DE) algorithm. The proposed optimization problem allows the network to adaptively achieve the optimal solution based on its required quality of service (Qos). Numerical results are given to verify our analysis.

    Raschke, Mathias; Schläpfer, Markus; Trantopoulos, Konstantinos

    2014-01-01

    Dynamical processes on complex networks such as information exchange, innovation diffusion, cascades in financial networks or epidemic spreading are highly affected by their underlying topologies as characterized by, for instance, degree–degree correlations. Here, we introduce the concept of copulas in order to generate random networks with an arbitrary degree distribution and a rich a priori degree–degree correlation (or ‘association’) structure. The accuracy of the proposed formalism and corresponding algorithm is numerically confirmed, while the method is tested on a real-world network of yeast protein–protein interactions. The derived network ensembles can be systematically deployed as proper null models, in order to unfold the complex interplay between the topology of real-world networks and the dynamics on top of them.

    2018-04-01

    In order to eliminating the artifacts and "staircase effect" of total variation in Compressive Sensing MRI, high degree total variation model is proposed for dynamic MRI reconstruction. the high degree total variation regularization term is used as a constraint to reconstruct the magnetic resonance image, and the iterative weighted MM algorithm is proposed to solve the convex optimization problem of the reconstructed MR image model, In addtion, one set of cardiac magnetic resonance data is used to verify the proposed algorithm for MRI. The results show that the high degree total variation method has a better reconstruction effect than the total variation and the total generalized variation, which can obtain higher reconstruction SNR and better structural similarity.

    This paper adapts Kuhn's conceptual framework to developmental episodes in the theory and practice of medicine. Previous attempts to understand the reception of Ignaz Semmelweis's work on puerperal fever in Kuhnian terms are used as a starting point. The author identifies some limitations of these attempts and proposes a new way of understanding the core Kuhnian notions of "paradigm," "progress," and "revolution" in the context of a socially embedded technoscience such as medicine.

    Tax reform proposals in the spirit of the 'flat tax' model typically aim to reduce three parameters: the average tax burden, the progressivity of the tax schedule, and the complexity of the tax code. We explore the implications of changes in these three parameters on entrepreneurial activity, measured by counts of firm births. The Swiss fiscal system offers sufficient intra-national variation in tax codes to allow us to estimate these effects with considerable precision. We find that high ave...

  7. Polarimetric purity and the concept of degree of polarization

    Science.gov (United States)

    Gil, José J.; Norrman, Andreas; Friberg, Ari T.; Setälä, Tero

    2018-02-01

    The concept of degree of polarization for electromagnetic waves, in its general three-dimensional version, is revisited in the light of the implications of the recent findings on the structure of polarimetric purity and of the existence of nonregular states of polarization [J. J. Gil et al., Phys Rev. A 95, 053856 (2017), 10.1103/PhysRevA.95.053856]. From the analysis of the characteristic decomposition of a polarization matrix R into an incoherent convex combination of (1) a pure state Rp, (2) a middle state Rm given by an equiprobable mixture of two eigenstates of R, and (3) a fully unpolarized state Ru -3 D, it is found that, in general, Rm exhibits nonzero circular and linear degrees of polarization. Therefore, the degrees of linear and circular polarization of R cannot always be assigned to the single totally polarized component Rp. It is shown that the parameter P3 D proposed formerly by Samson [J. C. Samson, Geophys. J. R. Astron. Soc. 34, 403 (1973), 10.1111/j.1365-246X.1973.tb02404.x] takes into account, in a proper and objective form, all the contributions to polarimetric purity, namely, the contributions to the linear and circular degrees of polarization of R as well as to the stability of the plane containing its polarization ellipse. Consequently, P3 D constitutes a natural representative of the degree of polarimetric purity. Some implications for the common convention for the concept of two-dimensional degree of polarization are also analyzed and discussed.

    By using lactose colored with erythrocin, we examined the effect of particle size on mixing degree during the preparation of triturations with a mortar and pestle. We used powders with different distributions of particle sizes, i.e., powder that passed through 32-mesh but was trapped on a 42-mesh sieve (32/42-mesh powder), powder that passed through a 42-mesh sieve but was trapped on a 60-mesh sieve (42/60-mesh powder), powder that passed through a 60-mesh sieve but was trapped on a 100-mesh sieve (60/100-mesh powder), and powder that passes through a 100-mesh sieve (> 100-mesh powder). The mixing degree of colored powder and non-colored powder whose distribution of particle sizes was the same as that of the colored powder was excellent. The coefficient of variation (CV) value of the mixing degree was 6.08% after 40 rotations when colored powder was mixed with non-colored powder that both passed through a 100-mesh sieve. The CV value of the mixing degree was low in the case of mixing of colored and non-colored powders with different particle size distributions. After mixing, about 50% of 42/60-mesh powder had become smaller particles, whereas the distribution of particle sizes was not influenced by the mixing of 60/100-mesh powder. It was suggested that the mixing degree is affected by distribution of particle sizes. It may be important to determine the mixing degrees for drugs with narrow therapeutic ranges.

    Successful development of Heavy Ion Fusion (HIF) will require scientific and technology advances in areas of targets, drivers and chambers. Design work on heavy ion targets indicates that high gain (60-130) may be possible with a -3-6 MJ driver depending on the ability to focus the beams to small spot sizes. Significant improvements have been made on key components of heavy ion drivers, including sources, injectors, insulators and ferromagnetic materials for long-pulse induction accelerator cells, solid-state pulsers, and superconducting quadrupole magnets. The leading chamber concept for HIF is the thick-liquid-wall HYLEE-II design, which uses an array of flibe jets to protect chamber structures from x-ray, debris, and neutron damage. Significant progress has been made in demonstrating the ability to create and control the types of flow needed to form the protective liquid blanket. Progress has also been made on neutron shielding for the final focus magnet arrays with predicted lifetimes now exceeding the life of the power plant. Safety analyses have been completed for the HYLEE-II design using state-of-the-art codes. Work also continues on target fabrication and injection for HE. A target injector experiment capable of > 5 Hz operation has been designed and construction will start in 2002. Methods for mass production of hohlraum targets are being evaluated with small-scale experiments and analyses. Progress in these areas will be reviewed

  10. Information Loss from Technological Progress

    International Nuclear Information System (INIS)

    Townsend, P D

    2014-01-01

    Progress in electronics and optics offers faster computers, and rapid communication via the internet that is matched by ever larger and evolving storage systems. Instinctively one assumes that this must be totally beneficial. However advances in software and storage media are progressing in ways which are frequently incompatible with earlier systems and the economics and commercial pressures rarely guarantee total compatibility with earlier systems. Instead, the industries actively choose to force the users to purchase new systems and software. Thus we are moving forward with new technological variants that may have access to only the most recent systems and we will have lost earlier alternatives. The reality is that increased processing speed and storage capacity are matched by an equally rapid decline in the access and survival lifetime of older information. This pattern is not limited to modern electronic systems but is evident throughout history from writing on stone and clay tablets to papyrus and paper. It is equally evident in image systems from painting, through film, to magnetic tapes and digital cameras. In sound recording we have variously progressed from wax discs to vinyl, magnetic tape and CD formats. In each case the need for better definition and greater capacity has forced the earlier systems into oblivion. Indeed proposed interactive music systems could similarly relegate music CDs to specialist collections. The article will track some of the examples and discuss the consequences as well as noting that this information loss is further compounded by developments in language and changes in cultural views of different societies

  12. Predictors of Associate's Degree Completion in Engineering and Engineering Technologies

    Science.gov (United States)

    Reys-Nickel, Lynsey L.

    The purpose of this ex post facto study was to describe completers and non-completers of associate's degree programs in engineering and engineering technologies and determine whether and to what extent completion in these programs is a function of selected student-related variables and institutional variables. Data from the 2004/2009 Beginning Postsecondary Students Longitudinal Study (BPS: 04/09) of associate's degree completers and non-completers in engineering and engineering technologies were accessed and analyzed through PowerStats, a web-based data analysis tool from National Center for Education Statistics (NCES). Descriptive data indicated that, proportionally, engineering and engineering technologies completers were mostly White, married, middle income, employed part-time, enrolled full-time, did not hold a high school diploma or certificate, completed Trigonometry/Algebra II, had a father who's highest education level was an associate's degree, but did not know their mother's highest level of education, completed remedial coursework, and started college with the goal of earning an associate's degree. While more males enrolled in the programs, males and females demonstrated similar completion rates, proportionally--with females showing a slightly higher percentage of completion. Results from the logistic regression further indicated that the variables significant to completion in associate's degree programs in engineering and engineering technologies were gender and enrollment size. Findings suggested that female students were more likely to earn the degree, and that the larger the institution, the more likely the student would become a completer. However, since a major limitation of the study was the small weighted sample size, the results of the study are inconclusive in terms of the extent to which the findings can be generalized to the population of students in associate's degree programs in engineering and engineering technologies. This study fills a

    We discuss the role of degrees of freedom different from the magnetic dipole in NpO 2 . Electric-quadrupole degrees of freedom appear to produce a large splitting of the main crystal-field (CEF) transition, due to the formation of mixed CEF-phonon states. A phase transition occurs at 25 K, and its phenomenology is inconsistent with a magnetic-dipole or an electric-quadrupole order parameter (OP). A magnetic-octupole of Γ 2 symmetry appears to be the best candidate OP. Such quantity can be detected in principle in a neutron diffraction experiment. The corresponding form factor is discussed.

    The models of f(R) gravity belong to an important class of modified gravity models where the late time cosmic accelerated expansion is considered as the manifestation of the large scale modification of the force of gravity. f(R) gravity models can be expressed in terms of a scalar degree of freedom by explicit redefinition of model's variable. Here we report about the study of the features of cosmological parameters and hence the cosmological evolution using the scalar degree of freedom of the f(R) = ξR n gravity model in the Friedmann-Lemaître-Robertson-Walker (FLRW) background

Approximately half of all U.S. medical schools offer combined MD-MBA degrees, and numerous executive MBA programs exist for physicians in practice. Physicians who enter management are considered change agents for healthcare improvement, yet they receive little support and encouragement from their medical teachers and practicing colleagues. This situation can be rectified by placing greater value on the role of business-trained physicians and subsidizing their tuition for business school.

    We study the effect of isospin degree of freedom, incident energy as well as system mass on the behavior of transverse momentum spectra, dN/p t dp t , of neutrons and protons. We find that most of the nucleons suffer soft collisions. The effect of isospin degree of freedom on transverse spectra diminishes with the increase in the incident energy. In Fermi energy region, transverse momentum spectra of both protons and neutrons show sensitivity toward the density dependence of symmetry energy. (author)

    We reconsider the options for cosmological holography. We suggest that a global and time-symmetric version of the Fischler-Susskind bound is the most natural generalization of the holographic bound encountered in AdS and De Sitter space. A consistent discussion of cosmological holography seems to imply an understanding of the notion of ''number of degrees of freedom'' that deviates from its simple definition as the entropy of the current state. The introduction of a more adequate notion of degree of freedom makes the suggested variation of the Fischler-Susskind bound look like a stringent and viable bound in all 4-dimensional cosmologies without a cosmological constant

  20. THE DEVELOPMENT OF A 1990 GLOBAL INVENTORY FOR SO(X) AND NO(X) ON A 1(DEGREE) X 1(DEGREE) LATITUDE-LONGITUDE GRID

    Sulfur and nitrogen oxides emitted to the atmosphere have been linked to the acidification of water bodies and soils and perturbations in the earth's radiation balance. In order to model the global transport and transformation of SO(sub x) and NO(sub x), detailed spatial and temporal emission inventories are required. Benkovitz et al. (1996) published the development of an inventory of 1985 global emissions of SO(sub x) and NO(sub x) from anthropogenic sources. The inventory was gridded to a 1(degree) x 1(degree) latitude-longitude grid and has served as input to several global modeling studies. There is now a need to provide modelers with an update of this inventory to a more recent year, with a split of the emissions into elevated and low level sources. This paper describes the development of a 1990 update of the SO(sub x) and NO(sub x) global inventories that also includes a breakdown of sources into 17 sector groups. The inventory development starts with a gridded global default EDGAR inventory (Olivier et al, 1996). In countries where more detailed national inventories are available, these are used to replace the emissions for those countries in the global default. The gridded emissions are distributed into two height levels (0-100m and and gt;100m) based on the final plume heights that are estimated to be typical for the various sectors considered. The sources of data as well as some of the methodologies employed to compile and develop the 1990 global inventory for SO(sub x) and NO(sub x) are discussed. The results reported should be considered to be interim since the work is still in progress and additional data sets are expected to become available
